Interspecific predation within Odonata is a critical yet underexplored aspect of their ecological interactions. This short communication reports a novel observation of Ischnura senegalensis preying upon Agriocnemis pygmaea in rice fields at the Faculty of Agriculture, Rajarata University of Sri Lanka. Documented on March 22, 2024, during the reproductive stage of the rice field, the predatory event involved a female I. senegalensis feeding on the head of a female A. pygmaea. Predation, characterized by the use of mandibles and lasting at least 15 minutes, reveals significant predatory efficiency and behavioral specialization. This observation fills a gap in the understanding of I. senegalensis feeding behavior in Sri Lanka and contributes to the broader knowledge of Odonate predator-prey dynamics. The findings highlight the importance of these interactions in maintaining ecological balance and suggest further research into the impacts of such predatory behaviors on agricultural ecosystems.

Background Injuries, particularly unintentional ones, are a neglected public health concern and are preventable or avoidable. Children in urban slums are especially vulnerable due to hazardous living conditions, inadequate supervision, and lack of safe sojourns or play areas. Since these injuries result in seeming spontaneous recovery, appropriate care being initiated by the primary care giver is questionable. Objective To assess the burden of unintentional injuries of unintentional injuries in pre-school going children aged 2-6 years in urban slums of Bhubaneswar, Odisha. To compare the knowledge of the 1st level care post-injury among the primary care givers against standardized prescribed care. Methods A cross-sectional descriptive observational study was conducted for over 2 years in urban slums under the Bhubaneswar Municipal Corporation (BMC), the capital city of Odisha. A total of 285 children aged 2-6 years, whose mothers consented to participate, were included in the study. Data regarding the type of injury and its management, as well as, associated socio-demographic factors, were collected using a pre-designed, pre-tested questionnaire. Descriptive statistics was used to derive the burden of unintentional injuries in children. The knowledge of the 1st level of care to be given after the common injuries was assessed among all the primary caregivers to detect the treatment and care gap. Results The majority of primary respondents were mothers aged 21-30 years (82.1%), The frequency of an episode of unintentional injury (occurrence in last 3 months) in the study population was found to be 58%. The most common type of injury reported was skin lacerations or tears, common site being in the upper and lower limbs. Males were more affected as compared to females (54.64 %) The reporting of unintentional injuries among the children was found to have significant association with the occupation of the father. Fathers who were unemployed or working as unskilled labor, their child’s probability of reporting an unintentional injury was found to be high, with p value coming to be statistically significant. Conclusion The study highlights the complex interplay of sociodemographic factors influencing unintentional injuries among children in urban slums and the need to create awareness among the primary caregivers, about the immediate management, so that chronic complications may be averted. It is difficult to avert injury as this age group is agile and nowadays supervision is challenging. Still, the knowledge of management would not just empower the caregiver, but also the growing child, who can attend to their younger siblings or themselves, whenever they get injured next. Further research with larger sample sizes is warranted to validate these findings and develop effective prevention strategies.

Objective Drawing up a balance sheet of 16 years follow-up of the sole case of Diamond-Blackfan anemia diagnosed in Togo with arguments of molecular biology. Observation T.S a boy, born on 5th september 2006 has been followed up since he was three months, for Diamond-Blackfan anemia (DBA) in whom there has been found the mutation of ribosomial protein RPS19 in july 2010. It was the first observation in Subsaharian Africa. The treatment by transfusions from december 2006 to december 2022 has been associated with iron chelation through deferoxamin and promptly with corticotherapy at the dosage of 2mg/kg/day. The corticotherapy has been reduced as a consequence of corticoresistance from the fourth week, then definitely interrupted after four months. The evolution is marked by a clinical improvement with a staturo-balanced curve, and during the last control of 28th december 2022, the child was 53 kg heavy and 160 cm tall. The monthly physical tests did not reveal any signs of eventual overloading and the echocardiography of 26th december 2022 was normal. On the biological plan, the rate of the haemoglobin had been stable around 50g/l as a resultant of a transfusion each 4 to 6 weeks of red blood cell pellet. The chelation of iron had been done through deferoxamin with a monthly control of serum ferritin. That serum ferritin was 738,39ng/mg at diagnosis before the beginning of transfusions and during the follow-up, we noticed an average of 2977,3ng/ml (range 1817,1ng/ml and 4448,5ng/ml) Conclusion Thanks to the regular transfusions derived from the survey of the parameters of iron and the use of deferoxamin, we have succeded in keeping alive during sixteen years a patient who caught a disease whose evolution is unpredictable.

A Pressure Sensitive Occlusal Contact Indicator for Implant Restorations: An Observational Clinical Evaluation

Dec 2022 DOI 10.14302/issn.2473-1005.jdoi-22-4360
Millstein PhilipCorresponding author Department of Restorative Dentistry, Harvard School of Dental Medicine, Boston, MA. USA

Contact intensity is a significant factor in immoveable implant restorations. This study visually compares the use of four occlusal contact indicators one of which measures contact intensity and surface area in a single subject. The need for an occlusal contact indicator that can be used with fixed implant restorations is examined. Three contact indicators used in practice are visually compared to a novel system where pressure sensitive information and surface area can be evaluated numerically and stored. Findings suggest that intensity and surface area should be measured upon implant placement. Limitations of this observational study are discussed. Directions for future research and more systematic study are offered

Background The origin of osteoarthritis, the most common disabling disorder of older adults remains uncertain. Aim This mini review examines the possible role played by various neuromuscular deficits in the osteoarthritis etiopathogenic process. Methods and Procedures Articles that haveaddressed the current topic of interest and were located in the PUBMED,Google Scholar, and Web of Science electronic data bases as of 2017-2022 were carefully sought and examined. Results Various neuromuscular mechanisms may have a bearing on the development and progression of osteoarthritis, but the data are largely unrelated and observational in nature. Conclusion More research to examine this issue is sorely needed and could have considerable merit in light of the growing populations of older adults at risk for disabling osteoarthritis in the face of few intervention options to help them to achieve an optimal functional level.

Validity of PIRO Score as an Assessment Tool for Mortality Risk of COVID-19 Pneumonia among Patients Admitted to World Citi Medical Center from March to August 2020. A Retrospective Observational Cohort Study

D. Natividad III GracianoCorresponding author Philippines.

Introduction In December 2019, cases of serious illness causing pneumonia and death were first reported in Wuhan, China.2 The clinical features of Corona Virus Disease-19 (COVID-19) are ranging from asymptomatic to multi organ dysfunction. The disease can progress to pneumonia, respiratory failure and death.4 Thus, a tool is needed that can predict the severity and in-hospital mortality risk of a patient with COVID-19 Pneumonia. The PIRO (predisposition, insult, response, and organ dysfunction) scoring was developed for use in the emergency department to risk stratify sepsis cases.15 Eventually it was adapted in pneumonia cases to predict its severity. Objective To validate PIRO score as an assessment tool for COVID-19 mortality risk among patients with confirmed COVID-19 RT-PCR test among patients aged 19 and above admitted in World Citi Medical Center from March 2020 to August 2020 Methods This study included 93 patients aged 19 and above admitted in World Citi Medical Center with a primary diagnosis of COVID-19 Confirmed with pneumonia between March 2020 to August 2020. The patients’ charts were retrieved from the hospital medical records and case notes were reviewed. A severity assessment score was developed based on PIRO score (Predisposition comorbidities and age; Insult multilobar opacities and viremia; Response shock and hypoxemia; Organ Dysfunciton) were extracted. The patients were stratified in four levels of risk: a)Low,0-2 points; b)Mild,3 points; c)High,4 points; d)Very High,5-8 points. The PIRO score and the clinical outcome were compared. The discriminative ability of PIRO score to predict mortality risk was evaluated under receiver operating characteristic curve (AUC). Results The PIRO score had an excellent predictive ability for in-hospital mortality (AUC0.9197). Analysis of variance showed that higher levels of PIRO scores were significantly associated with higher mortality (p<0.001). Patients with Mild PIRO risk category were 98.65% less likely to expire (p<0.001, 95%CI 0.0015) and High PIRO risk category were 94.47% less likely to expire (p<0.001, 95%CI 0.0124), both compared to patients with Very high PIRO risk category. Finally, Very High PIRO risk category were more than 44 times likely to expire compared to patients with Low, Mild and High PIRO risk category (p<0.001, 95%CI 11.738). Conclusions The PIRO score is a valid risk model that can be used to predict in-hospital mortality, that can help clinicians provide timely and accurate assessment, and hence appropriate management to patients with COVID-19 Pneumonia.

Serum Ferritin Level as a Prognostic Marker of 30 days In Hospital Mortality of Coronavirus Disease 2019 (COVID 19) Pneumonia at World Citi Medical Center: A Retrospective, Observational Cohort, Single Center Study

M. Quirit AllenCorresponding author MD.

Introduction The COVID-19 pandemic continues to affect a large swath of the global population. The Philippine records four hundred seventy-four thousand sixty-four (474, 064) confirmed COVID 19 cases since December 31 2020. The COVID 19 pandemic recently highlighted the role of systemic hyperferritenemia as a major cause of death. In this study, we were able to correlate the serum ferritin level and predict 30 day in hospital mortality in COVID 19 pneumonia. Objective The aim of the study is to investigate the correlation between serum ferritin level and disease mortality in COVID19 pneumonia with subset analysis on demographics and co-morbidities of patients with COVID 19 pneumonia. Methodology We reviewed the records of all laboratory confirmed COVID 19 patients from World Citi Medical Center from April 2020 up to April 2021.A statistically significant sample size of seventy nine (79) admitted patients were used in this study. A serum ferritin level was assayed using electrochemilumenescence immunoassay with a Roche COBAS analyzer. Results Result showed that high ferritin level is associated with in hospital mortality. With ferritin level of 1437.07ng/ml, poor clinical outcome and in hospital mortality was considered. We also observed that demographics and co morbidities of patients in this study were significant to predict in hospital mortality. Further sub-analysis of co morbidities such as Hypertensive cardiovascular disease, Type 2 Diabetes Mellitus, Chronic kidney disease, Liver disease, Chronic obstructive pulmonary disease and Cerebrovascular disease showed poor outcome which were directly related to ferritin levels with p value of <0.0001. Conclusion This study has demonstrated that elevated ferritin levels were shown to correlate with 30 day in hospital mortality as well as medical comorbidities such as Hypertensive Cardiovascular disease, Type 2 Diabetes Mellitus, and chronic kidney disease have shown significant evidence for in hospital mortality.

Observations and analysis of risk factors for GDV in a single institution: a case-control study

Mar 2020 DOI 10.14302/issn.2575-1212.jvhc-20-3225
di Virgilio FabrizioCorresponding author DVM, Clinique Vétérinaire Vet24 – 59700 – Marcq en Baroeul, France

Objective To evaluate/ determine the risk factors for dogs presented with Gastric Dilation- Volvulus (GDV) to a referral veterinary centre and to compare the results with those currently reported in veterinary literature. Materials and Methods The observational case-control study comprised a population of 215 dogs that attended the referral centre between 2000 and 2018. Medical records were searched for GDV and those matching the criteria were manually reviewed. A questionnaire was completed by the owners of the dogs involved in the study (both case and control populations) in order to gain further information that could be considered relevant to GDVs. In particular, information included the dogs’ behaviour and the dogs daily activities. Results The study included 115 cases of GDV and 115 controls. Out of the GDV dogs 13% (15/115) were small breed dogs and the remaining 87% (100/115) either large or giant breeds. The following risk factors for developing a GDV have been identified: Purebred dogs over 3 years old and either large of giant breeds, weighing > 30 kg. Foreign body ingestion, diarrhoea, and grass consumption were also associated to increase the likelihood in developing GDV. Behavioural temperament was not associated with developing GDV. Clinical Significance The findings support previously identified risk factors in the development of GDV, but characteristics related to the dogs temperament warrant further investigation. Knowledge of these results will further allow clinicians to make evidence‐based recommendations to owners in attempting to prevent GDV in dogs. Furthermore this paper confirms that the risk of GDV in certain breeds and in certain conditions is always high and that GDV is still an extremely current disease.

Blondon K.Corresponding author Division of General Internal Medicine, University Hospitals of Geneva, Geneva, Switzerland

Background Medication adherence remains a challenge for patient management. Changes in the drug regimen after a hospital stay can lead to confusion or misunderstandings. We implemented a structured patient-centered interview during which a computer-generated individualized medication plan was discussed and provided to patients at discharge. Objective To explore whether a medication plan can be a quality indicator, in terms of its content (quality) and its implementation in the resident’s workflow (feasibility). Methods An observational mixed method study with interviews of 174 patients from general internal medicine wards at 1 week and 1 month after discharge, and of 91 physicians at baseline. We report the quality of the medication plan in terms of content and state of completion. We describe feasibility for residents to complete this plan, as well as patient and resident satisfaction with the plan. Results 83% of participants received a medication plan. Physicians verified renal function (83%) to adapt doses but did not regularly assess for medication interactions (43%). Incomplete plans (61%), were due to blanks when physicians considered the information irrelevant for their patients. Error rate was <3%. Patients reported low use of their plan after discharge (64% found it useful after 1 week, whereas only 37% used it when taking their medication 1 week after discharge). Conclusion Although the plans were considered useful by both patients and physicians, their implementation could have been optimized by considering the overall process (creation to patient use). Mobile apps could help fill gaps in supporting patients for medication adherence.

Padaro EssohanaCorresponding author Hematology Department, Campus Teaching Hospital, University of Lome.

Objective Rosenthal's disease (RD) is a rare constitutional hemorrhagic disorder defined by factor XI deficiency. It is clinically characterized by the presence of minimal haemorrhage. We report the first observation of RD in Togo. Observation Mrs. G. A., 45 years old with no particular pathological antecedents, was referred for anemia in a context of chronic epistaxis. It was a spontaneous anterior exteriorization epistaxis often of great abundance, rocking and which evolved episodically. The patient received several transfusions for anemia. The ear-nose-throat examination was normal and a sinus CT scan found only an inflammatory process of the right maxillary sinus. The blood count showed microcytic severe anemia (2,2g/dl). Hemostasis tests showed a prolonged aPTT (57,9 seconds). Clinical examination documented an anemic syndrome with dry skin. Iron deficiency was found. The hemostasis balance confirmed aPTT elongation. Coagulation factors activity showed normal VIII and IX level, but moderate decrease of factor XI (32%). The family survey was not possible (orphan patient). It is recommended the setting under fresh frozen plasma (FFP) in case of a new episode. Follow-up is in progress. Conclusion In the event of any hemorrhagic syndrome, the isolated elongation of the aPTT must lead to a systematic analysis of intrinsic pathway factors

Irianov Yu.M.Corresponding author Russian Ilizarov Scientific Center for Restorative Traumatology and Orthopedic, Russia

Purpose of Study: To study reparative osteogenesis and tissue integration characteristics for implanting three-dimensional mesh structures of titanium nickelide into a bone cavitary defect. Material and Methods: The authors modeled cavitary defects of femoral metaphysis experimentally in Wistar rats divided into an experimental group and control one. The study duration was 60 days in total. The methods of radiography, those of light and electron microscopy, X-ray electron probe microanalysis used. Results: Under implantation the defect was filled with cancellous bone the volumetric density of which more than 1,5-fold exceeded control values (р < 0.001). The implant had biocompatibility, osteoconductive and osteoinductive properties, it stopped inflammatory processes. The membrane protective barrier which prevented connective tissue sprouting was formed on the implant surface in the defect periosteal zone. The osteointegrative junction was formed being persisted up to the end of the experiment. Reparative osteogenesis was performed by direct intramembranous and apposition type. Conclusion: The implant of three-dimensional mesh titanium-nickelide structures has marked osteoplastic properties, and it can be successfully used in orthopedic surgery.

Aljerf LoaiCorresponding author Department of Basic Sciences, Faculty of Dental Medicine, Damascus University, Damascus, Syria

Critical conditions are usually obtained for ignition in a self-heating solid system consisting of two components generating heat independently, one component being inexhaustible and the other exhaustible by either simple first order or autocatalytic reaction. Ignition depends upon whether the exhaustible component can cause a temperature rise in excess of the upper stationary, but unstable, value possible for the inexhaustible component reacting alone. The system provides a theoretical model for some commonly occurring examples of self-heating and ignition in porous solids containing oxidisable oils. It is shown that: (a) the ignition criterion of the model, which involves a nonarbitrary critical temperature increase, has a high degree of physical reality; (b) the model is, in principle, capable of predicting ignition from primary kinetic and thermal data; (c) it is likely to be possible often to make a reliable prediction of critical size for self-ignition in a two-component system at ordinary atmospheric temperatures by a simple extrapolation from small-scale ignition data, obtained at higher temperatures, in the same way as for ignition due to a single reaction. Examination of both adiabatic and non-adiabatic flame theories showed that a 'steady state' exists only under the special condition that a heat sink exists at the initial temperature. For the general case of freely propagating, non-adiabatic flames only a quasi-steady state can be achieved.

Objective To provide data on the consistency of recommended serving sizes of single bars and bags of chocolate confectionery products sold in UK supermarkets, in terms of weight and energy content. Methods Data were obtained from supermarket websites on the weight, calorific content and recommended serving size of all products classified as single bars or bags of chocolate confectionery products in at least two of the three supermarkets with the largest share of the grocery market in the United Kingdom. Results The number of servings per product varies from 1 to 3. Recommended serving sizes vary widely in terms of weight and energy content (ranges 18-83.4g and 88-265kcal respectively). Recommended serving sizes vary even between identical products sold in different size packages. Conclusions There is potential for consumer confusion over a reasonable serving size of chocolate products, especially in the wider nutritional context of well-described portion sizes for food categories such as fruit. Alternatively, the inconsistency may derive from a reasonable attempt to make front-of-pack labelling easy for consumers to understand by using intuitive fractions of the contents.

Elshafie OmaymaCorresponding author

Objective To evaluate the treatment outcomes of patients with Differentiated thyroid cancer (DTC) who underwent total thyroidectomy followed by RAI therapy at the Sultan Qaboos Comprehensive Cancer Care and Research Centre (SQCCCRC) in Oman. Methods This is a retrospective observational clinical study conducted at SQCCCRC. The study included all patients diagnosed with DTC who were admitted to SQCCCRC between June 2021 and November 2023. A total of 255 patients were identified and met the inclusion criteria for this study. Results The mean age at diagnosis was 39.9 ± 12.4 years (range: 14–79), with 78% of patients being female. The mean BMI was 30.3 ± 6.4 kg/m², with nearly half of the cohort (48.2%) classified as obese (BMI ≥ 30). Most patients had papillary thyroid carcinoma (92.9%), while follicular and Hürthle cell carcinoma accounted for 5.9% and 0.8% of cases, respectively. Based on the American Joint Committee on Cancer (AJCC) staging, 86.3% of the patients were classified as stage I and 3.9% as stage II. Six patients (2.4%) had stage IVB disease. According to American Thyroid Association (ATA) risk stratification the majority were low-risk. Patient age was strongly associated with disease stage. The distribution of metastatic cases varied by region, with the highest proportion observed in Dhofar. Most patients (87.1%) received a single dose of radioactive iodine (RAI), with a median cumulative dose of 3.7 mCi). At six months post-treatment, 70.2% of patients had a TG level < 0.2 ng/mL. Conclusion The outcome of therapy in majority of our patients is favorable with 72% having excellent biochemical response at last follow up. None of the patients with distant metastasis achieved excellent response and a high proportion of them came from the Dhofar governorate, a targeted intervention would be of benefit. Low risk patients require special attention and may need radioactive iodine during follow up, unlike other regions and hence warrant very close follow up and further review to establish the best practice guidelines in our region.

From Pelvis to Foot: A Functional Approach to Preventing Ankle Sprains in Athletes

Jun 2026 DOI 10.14302/issn.2694-2283.jsem-26-6247
Quintero GabrielCorresponding author

Background Ankle sprains are among the most common injuries in sports, often characterized by high recurrence rates despite appropriate local treatment. Traditional approaches primarily focus on the injured joint, with limited attention to proximal biomechanical factors that may predispose athletes to injury. Objective To propose a functional, longitudinal kinetic chain model in which sacroiliac joint dysfunction may act as a predisposing factor for ankle sprain/strain injuries in athletes. Methods This paper presents a clinical hypothesis based on biomechanical reasoning and observational findings. The proposed model describes how sacroiliac joint dysfunction, particularly posterior innominate rotation (PI), may lead to pelvic obliquity and functional leg length discrepancy. These changes may induce compensatory femoral external rotation and foot toe-out, altering ground contact mechanics during gait and running. Results (Hypothesis) The altered alignment and loading pattern may increase the vertical impact force and modify the ground reaction vector on the functionally shorter limb, resulting in reduced mechanical stability at the ankle during heel strike or foot contact. Over time, this may increase susceptibility to inversion or eversion injuries, manifesting clinically as recurrent sprain/strain. Conclusion Ankle sprains in athletes may, in some cases, represent the distal expression of a proximal biomechanical imbalance. Incorporating assessment of the sacroiliac joint and the longitudinal kinetic chain into routine clinical evaluation may improve injury risk identification and contribute to more effective prevention strategies. Further research is needed to investigate this proposed relationship.

High-Throughput Complex Disease Modeling for Ethical Drug Discovery: Clinical Relevance of a NAM Platform for Cancer Biomarker Development

Faisst Arne-C.Corresponding author

The development of tumor biomarkers derived from blood, or its components, has become pivotal in advancing early cancer diagnosis. Malignant transformations induce cancer-specific alterations in the transcriptome, proteome, and secretome of tumor cells. Recent studies highlighted similar alterations in peripheral blood mononuclear cells (PBMCs) in cancer patients, which appear to mirror the state of transformation in tumor cells. These findings suggest an intercellular communication–driven mechanism rather than a systemic inflammatory response and, in addition to current ctDNA-based liquid biopsy biomarkers, point to a novel, simple, and highly robust approach for the early detection of cancer. Using this phenomenon to advance PBMC-based biomarker development, it will be essential to achieve 3D in vitro tumor models that reproduce a highly physiological tumor microenvironment (TME). Likewise, more enhanced 3D ex vivo models are required to enable the replication of cell-to-cell and organ-to-organ communication. These systems will guide the self-organization of mixed microenvironments derived from different tissues and enable them to accurately reproduce the molecular connections underlying these alterations. In this study, an innovative new modular 3D co-culturing approach was used to expose PBMCs to lung tumoroids, under physiologically relevant conditions. Changes in DNA fragmentation of PBMCs in the presence of lung cancer were quantified and used as a biomarker. To validate the predictiveness of this biomarker, our results were compared with clinical data from a clinical evaluation study. Similar to the clinical trial observations, PBMCs, when exposed to lung tumoroids, showed a significantly lower level of DNA fragmentation (37%). This modular 3D co-culturing model showed a predictiveness of the clinical data of > 90%, demonstrating its power to monitoring cell-to-cell communication effects and support the development of blood-based biomarkers.

Interactions Between Natural Nuclear Reactors and Microbial Evolutionary Processes

Feb 2026 DOI 10.14302/issn.2689-4602.jes-25-5926
Easttom ChuckCorresponding author

The impact of ionizing radiation on genetic change is well established, yet the extent to which naturally occurring radiation fields have influenced evolutionary trajectories remains incompletely understood. This study examined correlations between microbial evolution and the radiation and geochemical environments associated with natural fission reactors, with emphasis on the Oklo–Bangombé system in present-day Gabon, Africa. The current paper compares plausible doserate regimes adjacent to reactor zones with published observations of radiationinduced phenotypes, geneexpression changes, and repair strategies in model organisms and complex biotas. This study further considers indirect mechanisms (e.g., water radiolysis, redox restructuring, tracemetal mobilization) by which natural reactors could have modulated ecological selection pressures over long timescales. The synthesis supports the plausibility of three interacting pathways: (i) increased mutation supply under low, chronic dose rates; (ii) selection in oxidantrich, redoxstratified niches; and (iii) metabolic subsidies (e.g., H₂) from radiolysis that support chemotrophic guilds. Although temporal–spatial associations exist between reactor activity and biological innovations preserved in Paleoproterozoic strata of Gabon, current evidence remains correlational rather than demonstrably causal. The study further outlines testable predictions and experimental designs capable of discriminating among these mechanisms.

Efficacy and Safety of Lercanidipine Combination in Hypertensive Patients

Dec 2025 DOI 10.14302/issn.2329-9487.jhc-25-5778
S Kallistratos ManolisCorresponding author

Calcium channel blockers (CCBs) are widely used for the treatment of arterial hypertension, but they differ in terms of pharmacology, tolerability, and pleiotropic actions. Lercanidipine, a highly lipophilic third generation dihydropyridine, reduces blood pressure (BP) effectively as monotherapy and in combination without inferiority to other major antihypertensive classes. We systematically searched PubMed and the Cochrane Library (last update: September 1, 2025) and screened reference lists for additional studies. Evidence from dose finding trials, randomized controlled studies, large observational cohorts, and meta analyses shows clinically meaningful reductions in office, home, and ambulatory BP with lercanidipine, including in patients with diabetes, obesity, chronic kidney disease, or high cardiovascular (CV) risk. Fixed- dose combinations with renin angiotensin system blockers (e.g., enalapril) provide greater BP reductions than monotherapy and are associated with favorable neurometabolic profiles. Beyond BP control, lercanidipine improves central hemodynamics and arterial stiffness, favors endothelial biology, and contributes to left ventricular hypertrophy regression. Across comparative trials, lercanidipine is generally better tolerated than older dihydropyridines. Presents lower rates of vasodilatory adverse events, less sympathetic activation, while discontinuations due to adverse events are uncommon. Overall, lercanidipine particularly within single pill combinations offers effective, durable BP lowering across diverse patient profiles with a favorable safety and tolerability profile and pleiotropic benefits that extend beyond BP reduction.

Radio-Induced Maxillary Angiosarcoma: About a Case

May 2025 DOI 10.14302/issn.2379-8572.joa-25-5504
Hachemi MohamedCorresponding author

Introduction Angiosarcoma is a rare malignant tumour from fast-evolving and aggressive vascular endothelial cells that accounts for 1% of all sarcomas. The sinus location of angiosarcoma is exceptional. The clinical polymorphism of this tumour may cause a delay in diagnosis. Risk factors are not always understood. However, a history of radiation therapy for locoregional cancer and/or lymphedema is most commonly found. The prognosis remains bleak with an overall five-year survival of 35 to 40%. Objectives The authors discuss the diagnostic, therapeutic and prognostic modalities and difficulties of this tumour. Observation: The authors report a case of maxillary sinus angiosarcoma confirmed by radio-induced secondary CD34 immunohistological staining in a 40-year-old man having a history of hemangioendothelioma treated with conservative endoscopic surgery and adjuvant radiotherapy 15 months earlier. Discussion This lesion is rare in the ENT sphere and may be confused with a benign tumor in its early stages. Only histological examination with immunohistochemistry can confirm the diagnosis (factor VIII, CD34 and CD31 antigens). Treatment consists of a wide resection followed by radiotherapy, hence the need for early diagnosis in the metastatic phase, first-line treatments include doxorubicin or paclitaxel weekly. Conclusion Radio-induced angiosarcoma is a rare malignant tumour, it occurs in patients who have received conservative treatment and radiation therapy for nasosinusitis cancers. Angiosarcomas of the nasal passages remain a diagnostic and therapeutic challenge due to their local and general aggressiveness.

A Study on the Feasibility and Utility of Continuous Glucose Monitors in Elite Football

Jan 2025 DOI 10.14302/issn.2694-2283.jsem-24-5363
Harries SophieCorresponding author

Physiological performance may be limited by reduced systemic glucose availability to working muscles. Continuous glucose monitors (CGM) measure interstitial glucose every 1-15 minutes, offering a practical way to assess glucose during sporting activity. However, empirical research has predominantly focused on endurance-based sports, whereas glucose responses during professional competitive football matches remain unknown. This study evaluated the feasibility and utility of CGM in professional football. Eight professional, male outfield footballers from the English third tier participated in the study. Participants completed a 14-day food diary control period, followed by a 28-day observation period wearing CGM devices during six matches and sixteen training sessions. CGM devices remained in situ for 98% of training sessions and matches. Mean glucose concentrations were 6.5 ± 1.2 mmol/L during training sessions, 7.5 ± 2.1 mmol/L during match play, and 5.4 ± 0.3 mmol/L overnight. No significant differences were found between glucose concentrations during match play (p = 0.060) or training (p = 0.510), compared to overnight fasted glucose concentrations. There was also no difference between training and match-play glucose concentrations (p = 0.788). Glucose concentrations were highly individualised, with one player displaying minimal change throughout match play (-0.2 mmol/L) whereas another experienced increases of up to 5.8 mmol/L. Non-nutritional factors appeared to influence glucose concentrations; participants (n=3) who used nicotine pouches displayed an transient increase in blood glucose in the 10-55 minutes after administration. This study concludes that CGM use in professional football is feasible for assessing individual glucose responses to  training and match-play.

Disruption of Hydrogen Bonding Network Decreases Catalytic Diversity of Chloroperoxidase via Abolishing Both Chlorination and Dismutation Activities

Nov 2024 DOI 10.14302/issn.2690-4829.jen-24-5291
Wang XiaotangCorresponding author

The perpendicular orientation of the proximal alpha helix to the heme plane in chloroperoxidase (CPO) maximizes the influence of its intrinsic helix dipole that has been shown to reduce the “push-effect”, thereby increasing the heme redox potential and fine-tuning the catalytic capabilities of CPO. We investigated the effects of a disruption of the hydrogen bonding network between R26-N37 and A27-N33, formed by the proximal alpha helix, on the CPO structural stability and catalytic profile using site-directed mutagenesis and spectroscopy. The mutant CPO (R26A, N33A, and R26A/N33A) exhibited significant tertiary structural changes and distinct heme coordination, likely, due to destabilization of the proximal helix as a result of the disruption of the proximal hydrogen bonding network. In line with these observations, biochemical characterizations showed that all mutants displayed dramatically different activity profiles relative to that of the WT CPO. Mutant epoxidation and peroxidation activities were markedly enhanced, especially in the R26A/N33A CPO mutant. Moreover, all mutant CPO enzymes exhibited broader pH profiles in both epoxidation and peroxidation activities, including a shift in the optimal peroxidation activity towards pH 3.5 as opposed to pH 2.75. Conversely, the dismutation activity (pH 3.0-5.5) was almost completely lost while chlorination activity (pH 2.75-5.0) was virtually non-existent in all CPO mutants. Our results demonstrate the important role the R26-N37 and A27-N33 hydrogen bond pairs play in the heme coordination and tertiary structure of CPO defining its catalytic capabilities, and also suggest the importance of the proximal helix stability and orientation.

Internal Jugular Phlebectasia; A Challenging Neck Mass in Children

Oct 2024 DOI 10.14302/issn.2691-5014.jphn-24-5310
Alsaeed GihadCorresponding author

Cystic neck masses are uncommon in children, and a minority of them are soft. Internal jugular vein phlebectasia (IJVP) is a rare cause of soft neck cysts. It presents usually as a unilateral soft neck mass of changing size. In most cases it is unilateral, right sided and predominantly in males. Imaging study modalities are diagnostic and helpful for observation and follow up. In the vast majority of cases, it decreases in size with time requiring only conservative treatment. However, surgery might be necessary in large or complicated phlebectasia. IJVP is underdiagnosed or misdiagnosed especially in pediatrics, with few cases documented in medical literature. To improve awareness of presentation and management-plan of this rare case, the authors present an extremely rare case of huge left internal jugular phlebectasia in a 14 year-old boy worsened and complicated over years of wait and see approach that needed surgical treatment.

COVID-19-Induced Changes in the Fibrin Network of Pulmonary and Renal Microthrombi

Luna-Rivero CesarCorresponding author

Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection often causes coagulation disorders that affect highly vascularized organs, such as the lungs and kidneys. Objective The objective of this study was to report the histopathological findings of variations in the fibrin pattern of pulmonary and renal microthrombi in patients who died from SARS-CoV-2 infection. Methods Minimally invasive autopsies were performed on 40 patients to collect lung (n=40) and kidney (n=16) tissue samples. Histochemical and immunohistochemical staining techniques were used for histopathological analyses. Premortem laboratory data were obtained from the patients' electronic medical records. Results The lung tissue showed a patchy pattern, characterized by areas of both minimal and severe damage. The most significant histopathological finding was the detection of thrombi with fibrin structures organized into discrete star-shaped units, which were more frequently observed in areas with severe lung injury than in those with minimal lung injury (p = 0.012). Star-shaped fibrin structures were also observed in the renal glomerular capillaries. Immunohistochemical staining revealed the presence of platelets and the procoagulant proteins von Willebrand factor (VWF) and Factor VIII within the star-shaped fibrin thrombi. Patients with star-shaped fibrin thrombi had higher levels of the systemic inflammatory indicators C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio (NLR). Conclusion Our observations suggest that the inflammatory microenvironment resulting from SARS-CoV-2 infection may contribute to the formation of star-shaped fibrin units in the pulmonary and renal microthrombi.

Delving into the Ideas of Charles Darwin: A Study of His Pre-Beagle Musings, Beagle Expedition, and Subsequent Developments

Sep 2024 DOI 10.14302/issn.2689-4602.jes-24-5245
Sanghani HunarCorresponding author

Charles Darwin's exploration of the Galápagos Islands in 1835 and his subsequent formulation of the theory of evolution in 1839 were significantly influenced by his observations of land-birds, including finches, larks, owls, and mockingthrushes. Despite a primary focus on geology during his voyage on the HMS Beagle, Darwin meticulously documented various species in his field notebooks. Early observations during his youth at Edinburgh University and the Beagle expedition reflected Darwin's growing curiosity about species variation. However, it was not until his return to England and his interaction with ornithologist John Gould that Darwin began to recognize the significance of the finches he had observed in the Galápagos. This review synthesizes existing literature on Darwin's transition from geological interests to his groundbreaking insights into evolution. By examining primary sources, historical interpretations, and contemporary analyses, this paper highlights how Darwin's observations and Gould's influence shaped his revolutionary theory of species transmutation—the gradual transformation of one species into another over time. The review aims to provide a comprehensive understanding of Darwin's contributions, illustrating how his Galápagos observations and collaboration with Gould laid the foundation for modern evolutionary biology and continue to influence scientific thought on species adaptation and natural selection.

Total Daily Energy Expenditure is Overestimated by Dietary References Intake Equations Compared with Doubly Labeled Water in A Sample of Brazilian Adolescents

Aug 2024 DOI 10.14302/issn.2379-7835.ijn-24-5155
Bérgamo Silva LaraCorresponding author

Objective This report aimed to compare the total daily energy expenditure (TDEE) of adolescents measured by doubly labeled water (DLW) with the 2005 and 2023 dietary reference intake (DRI) equations proposed by the Institute of Medicine (IOM) in a sample of Brazilian adolescents. Methodology: This is a cross-sectional and observational study with a convenience sample of 15 obese and eutrophic adolescents, aged between 11 and 14 years, from public schools and the obesity outpatient clinic of the Clinics Hospital of the Ribeirão Preto Medical School – University of São Paulo (HC FMRP-USP) in Brazil. Were obtained stature and weight by conventional methods and used to calculate the body mass index (BMI) to determine the nutritional status. Fat-free mass (FFM) was measured using dual-energy X-ray absorptiometry. Energy expenditure was determined by DLW and estimated by the 2005 and 2023 DRI equations. The level of physical activity was measured with the ActivPAL™ accelerometer to classify adolescents within the equations. Results: Forty-seven percent of the sample were eutrophic and 53% were obese. The adolescents were classified as somewhat active according to the average number of daily steps. The DLW-derived TDEE and the TDEE derived from the 2005 and the 2023 predictive equations are presented as means, standard deviations, and 95% confidence intervals (CI). The 2005 and 2023 DRI equations produced significantly higher values than the DLW-determined TDEE (56.2% and 57.2%, respectively). Conclusion: Additional studies with Brazilian adolescents should be conducted to propose more accurate and specific predictive TDEE equations.

Tai-Chi Exercise Training and its Promising Therapeutic Impacts Among Older Community Dwelling Adults with Painful Knee Osteoarthritis

Marks RayCorresponding author

Knee joint osteoarthritis, a chronic condition resulting in considerable disability, particularly in later life, not only impacts life quality significantly and severely, but is also strongly associated with the persistence of intractable pain, depression, helplessness, and a high falls injury risk. This narrative overview synthesizes the knowledge base regarding painful knee osteoarthritis and what is known about Tai Chi exercise participation in the context of reducing knee joint disability and its associated risk of one or more injurious falls, as well as pain and depression. To this end, all relevant articles published in the English language on the topic were sought. While most reports rely on Eastern observations, rather than Western medicine studies, collectively, these data reveal that Tai Chi practiced widely in Asia for many centuries may have an enormous positive impact on reducing distress and increasing function and autonomy among older adults living in the community and diagnosed as having knee osteoarthritis. They specifically suggest the increasing numbers of older adults diagnosed as having knee osteoarthritis can safely practice selected Tai Chi exercises with the expectation that consistent applications will enhance mobility, reduce pain and depression, plus instability and possible injurious falls, while reducing fatigue, even if surgery is forthcoming.

Duguma ArarsaCorresponding author

Reproductive performance is an essential trait of cows in dairy cattle. The effect of different factors on reproductive performances and sex ratio difference in dairy cattle were not well documented in Ethiopia. In this research, cross-sectional study was conducted from December 2021 to June 2022 in Hawassa city to assess reproductive performances and effect of breeding methods on sex ratio difference of newborn. Questionnaires and observational study were used to collect data. In this study, the mean+SE of age at first service was 17.53+0.035 with difference of relatively one month from onset of puberty. The mean number of services per conception was higher in animals breed naturally (1.87+0.056) as compared to AI (1.69+0.049). Higher conception rate of 74.26% was obtained in age group of <4years as compared to old age >6years at rate of 4.11% with statistically significant difference (P<0.05). Animals with medium level of milk production (15-20L/day) more conceived to first service 43.14% than higher milk production group (20-25L/day) with 35.59%. The presence of reproductive problems significantly affect conception rate to first service with higher conception rate of 54.47% in negative animals and 22.41% in animals with reproductive problems. Conception rate was increased with increasing number of services in both breeding types. Sex of newborn was not significantly affected by breeding methods used and difference in the study area. Generally this research found that reproductive performances and use of AI in the study area were satisfactory even though age, level of milk production and presence of reproductive health problems had significant impacts on performances. In order to sustain and improve reproductive performances age, reproductive health problems and breeding management should be considered. Therefore, reproductive health management and application of AI for genetic improvement should be well practiced to improve dairy cattle reproductive performances.

Dangwe Temoua NaibeCorresponding author

Introduction Rheumatic heart disease is mostly common in low-income or developing parts of the world, such as Sub-Saharan Africa, with a high morbidity and mortality rate. There are few data that are available in Chad on rheumatic heart disease. Our objective was to study the clinical, echocardiographic, therapeutic, and progressive aspects of rheumatic heart disease at the Renaissance University Hospital Center and the National Reference Teaching Hospital in N’Djamena, Chad. Patient and methods This was a prospective, multicenter and observational cohort study, covering a consecutive series of patients consulted and/or hospitalized for rheumatic heart disease, documented by an echocardiogram from January 2015 to January 2021. Results Among the 4456 patients consulted and/or hospitalized, 398 cases of rheumatic heart disease (8.9%) were collected, and 364 patients had met the inclusion criteria. The mean age was 31.2 ± 14.4 years, and 193 patients (53%) were female. On admission, heart failure was present in 214 patients (58.8%), ischemic stroke in 10 patients (2.7%) and supraventricular arrhythmias such as atrial fibrillation in 94 patients (25.8%) and atrial flutter in 6 patients (1.6%). Mitral regurgitation was observed in 49.7% (n=181) of cases, aortic regurgitation in 33.2% (n=121), mitral stenosis in 31.3% (n=114), and aortic stenosis in 7.7% (n=28). At least two valvular disorders were combined in 48.4% of cases. A surgical intervention such as a heart valve replacement and/or valvuloplasty was performed in 80 patients (22.2%). At least one rehospitalization was noted in 56.9% of patients. Forty-two of the 150 patients free of heart failure at inclusion (28%) had experienced the first episode of decompensated heart failure during follow-up. On the other hand, in 119 patients (55.6%), it was the second episode of decompensated heart failure. Other progressive complications included atrial fibrillation (13.8%), thromboembolic complications (6.3%), infective endocarditis (6.0%) and prosthetic valve dysfunction (1.4%). Altogether, the mortality rate was 10.4%. It was 9.9% in non-operated patients compared to 12.5% in operated patients (p=0.49). Conclusion The present study shows that morbidity and mortality of rheumatic heart disease remain high in our context and often affect children, young adults, and women. Treatment is essentially based on cardiac surgery which is not available in Chad.

Nutrition during pregnancy is of utmost important to ensure positive pregnancy outcomes after delivery. This study examined the utilization of nutrition services provided at health facilities to pregnant women. A cross sectional study design, involving 105 pregnant women and 5 RCH providers from 2 health facilities was used. Structured questionnaires, and structured observations were used in data collection. SPSS software version 25 was used in data analysis. Results showed that, RCH providers had inadequate nutrition knowledge due to limited nutrition courses during nursing training and on job trainings/seminars. All RCH providers advised that, nutrition knowledge is important to pregnant women hence they were responsible for its delivery. In adequate staff and lack of teaching materials contributed to the poor delivery of quality nutrition education to all pregnant women as it was observed that there is variations in nutrition information given to women.   More than a half of all pregnant women (63%) started their ANC clinic during their first trimester where they received all nutrition services including education on importance of nutrition during pregnancy which helped them to be aware of the relationship between diet maternal nutrition and birth outcomes (63.8%). Most common food group that has been consumed more by pregnant women was grains, roots and tubers and plantains, while also there was high consumption of fruits and vegetables by all women as they are being more emphasized during routine clinics to prevent anemia. Also, there are some barriers that were identified by the service providers which makes their work difficult such as inadequate teaching materials like brochures, posters and jobs aids, also shortage of staff was found to be the core cause of services being provided occasionally as it is the RCH nurse who provide the education and counselling as there is no any nutritionist hired by government at the facility. Regional and district nutrition officers should coordinate and conduct on job training to health providers on issues related to nutrition in order to update their nutrition knowledge and facilitate clear, accurate and more evidence based nutrition information delivered.

The growth characteristics of Conraua goliath (Boulenger, 1906), an endemic and endangered species in Cameroon, were evaluated in its natural habitat between October 2021 and November 2022 in order to contribute to its domestication and conservation. For this purpose, 139 specimens (55 males, 55 females, and 29 individuals of undifferentiated sex) were collected by fishermen from 3 sites (Loum, Penja, and Nlonako) in the Department of Moungo, Coastal Region of Cameroon. The frogs were measured, and their growth parameters were determined after dissection and macroscopic and microscopic observations. The maximum size observed is 33.5 cm (SVL) and 2529 g body weight (BW), and the minimum size is 5.3 cm (SVL) and 12 g body weight (BW). This species is more abundant in the rainy season, in frogs between 18 and 24 cm, and has a Caucasian and uni-modal size structure. Independent of sex and season, this species has a significant and high regression coefficient between length, weight, and isometric growth pattern. However, this growth varies according to sex. It ranges from isometric in males (b = 2.82) and undifferentiated sexes (b = 2.85) to negative allometry in females (b = 2.21). The condition factor K ranges from 3.28 to 14.24 (mean: 7.80 ± 1.95) and fluctuates according to the sex and size of the frog. According to our results, this species has a large size and a high growth rate and could therefore be an excellent candidate for domestication to ensure its conservation. However, studies on reproductive characteristics are needed to complete this work.

Non-Specific Steroid Cell Tumor of The Ovary: Case Report And Review of The Literature

Dec 2022 DOI 10.14302/issn.2574-4526.jddd-22-4151
Darouichi M.Corresponding author Institute Medical Champel, 1206.Champel, Geneva, Switzerland

Steroid cell tumors of the ovary are particularly rare, secreting sex hormones, characterized by steroid cell proliferation and represent only 0.1% of all ovarian tumors. They are classified into three subtypes according to their cell of origin: stromal luteoma, Leydig cell tumors and a third subtype of unknown lineage corresponds to a not specified steroid cell tumor (SCT-NOS). This third subtype accounts for 60% of steroid cell tumors. The clinical manifestations of SCT-NOS can take many forms, including pain, abdominal distension, but perhaps the most visible presentations are those related to hormonal activity and virilization of the tumor. We present a rare case of a 48-year-old woman with vaginal bleeding and a history of trunk obesity, hirsutism for 2 years and hypothyroidism with hormone replacement therapy. Clinical examination revealed a characteristic of obesity, virilization. Serum testosterone was 3.62 µg / L and CA-125 was 40.67. Magnetic resonance imaging identified a left ovarian solid mass and histopathology confirmed a steroid cell tumor not specific. The patient underwent exploratory laparotomy and left salpingoophorectomy. Macroscopically, the mass is well circumscribed, solid, homogeneous and yellowish. Microscopically, the tumor is mainly composed of eosinophilic or vacuolar granular cytoplasm. Immunohistochemistry showed that the tumor cells were strongly positive for inhibin. The postoperative period was uneventful. Through this rare observation, we will discuss the aspects that characterize this type of tumor and present some guidelines to be used in the differential diagnosis, as well as the difficulties encountered in the clinical, radiological and therapeutic fields.

Intrathoracic foreign bodies secondary to penetrating wounds are rare in children. We report the observation of a 10-year-old patient who presented an intrapulmonary metallic foreign body following a playful accident. Its migratory aspect, highlighted by imaging, required urgent extraction which was performed by thoracotomy, with good clinical outcome. The interest of the question lies in the circumstances of the incident, the type of foreign body and the terrain.

Aim and Objective Despite the growing concerns about the relationship between exposure to radiofrequency radiation (RFR) and detrimental health effects due to the changes in biological processes of experimental animals, there is still ongoing debate on the significance of these findings in causing significant public health problems with the growing advancement in internet technology. The aim of this study is to review existing literature on the effects of high RFR on wistar rats. Method A search was conducted on Google scholar and PubMed to identify relevant peer-reviewed articles to be included into the review. Studies eligible for inclusion included free full text articles on wistar rats exposed to ≥ 2.45GHz RFR conducted in the past 5 years. Studies included in this review were written or transcribed in English language. From 286 titles, 36 eligible studies were included in the review and assessed for quality using the Strengthening the Report of Observational Studies in Epidemiology – Veterinary Extension (STROBE-Vet) quality assessment tool. Results Studies included in this review generally had good quality (>60%) based on the STROBE-Vet assessment. This review identified numerous biological changes in wistar rats exposed to high RFR including variations in biochemical, cholinergic, genetic, histopathologic, psychological, optical, and dermatological parameters. In this review, studies identified variations in protein and liver enzymes while high RFR was found to induce oxidative stress and cellular damage of exposed wistar rats compared to the unexposed groups. This was seen in the changes in protein, lipids, enzymatic and non-enzymatic antioxidants. Studies also identified changes in expression of genes and neurotransmitters with imbalance in hormones. In addition, this review identified structural changes of cells, tissues and organs indicative of apoptosis, damage and death. Exposed rats were identified to have behavioral changes indicative of anxiety and memory decline while studies identified optical and dermatologic changes in exposed rats compared to the unexposed. Conclusion With numerous biological changes identified in wistar rats exposed to high RFR, there is an increasing risk of detrimental health events giving the advancement in internet technology and limited regulations to control exposures to RFR. Therefore, studies should be conducted to identify strategies to mitigate human exposure to RFR while policies are developed and enforced to protect human health.

Introduction Worldwide, the Chronic Obstructive Pulmonary Disease (COPD) is a major public health concern; On the basis of epidemiologic data, by 2020, COPD will be the third leading cause of death worldwide. Objective To assess the frequency of Microalbuminuria and the presence of Hypoxemia in patients with COPD. Materials and Methods Study Design Cross-sectional observational study. Place of Study Department of Medicine & Respiratory Medicine in Dhaka Medical College Hospital (DMCH). Study Period Six months after approval of the protocol Study Population Patient suffering from COPD and admitted in Department of Medicine & Respiratory medicine, DMCH, Dhaka, Bangladesh. Total 100 samples were included in this study. COPD usually presents with a history of chronic cough with sputum production or exertional breathlessness which may be associated with relevant clinical findings and a post-bronchodilator FEV1/FVC less than 0.7. In most cases it is associated with smoking Results Total 100 patients of COPD were included in the study. Mean age was 58.16±5.4 years ranging from 50 to 74 years. Out of 100 patients, majority (42%) were from age group 55 to 60 years. Among all, 82% patients were male and 18% were female, of 100 patients, majority (30%) were day laborer. Only 2% were unemployed. The percentage of housewives was 18%. Other 34% were businessman and service holders. COPD severity was assessed using GOLD guideline. Out of 100 COPD patients, 38% had severe COPD (GOLD stage III). 16 % patients were in mild (Stage I) and 32% patients were in moderate stage (Stage II). The condition was very severe for 14% patients (Stage IV). Of 100 COPD patients, 30% had microalbuminuria. Among 100 COPD patients, chance of microalbuminuria increases among COPD patients with the increase of age significantly. There is smoking history of 36 pack year for COPD patients with microalbuminuria. Of 100 patients 26% were hypoxemic. The average forced expiratory volume (FEV1%) was 37.40 with standard deviation 14.48 for patients with microalbuminuria. The PaO2 and PaCO2 is 63.06 with standard deviation 7.09 and 46.09 with standard deviation 2.43 for COPD patients with microalbuminuria respectively. All of these characteristics are significant with p-value 0.00. However, the body mass index (BMI), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were not found significant. The patients who had PaO2 less than 70 mmHg were considered hypoxemic. The patients who had microalbuminuria among them 87% were hypoxemic. Only 13% patients were free from hypoxemia who had microalbuminuria. Patients without microalbuminuria had no history of hypoxemia. There is significant relation exists between hypoxemia and the presence of microalbuminuria (p<0.5). Conclusion In this study, about one-fourth of the patients have hypoxemia and more than one fourth of the patients have microalbuminuria. Stage III was more frequent among the study population but there was no association between severity grading and presence of microalbuminuria. However, significant relation is found between co-existence of both microalbuminuria and hypoxemia in COPD patients.

Background SARS-CoV-2 pandemic represented an unexpected psychological stress, being a major threat to health and limiting daily’s life, especially for the fragile population. How could the people with (pw) Multiple Sclerosis (MS) cope with this emergency? Objective To observe the pwMS’s psychological reaction in comparison with non affected persons and to evaluate the impact of lifestyle changes on psychological symptoms, due to the pandemic. Methods The study was observational, retrospective, controlled, focused on good clinical practice and conducted at Niguarda Hospital. PwMS and controls filled a web survey containing anamnestic data, habits, depression and anxiety self-questionnaires. The primary outcome was the pwMS’s psychological anxiety and depression score compared with controls. Results On April, 10 2020, 88/165 pwMS and 187 controls joined the study. Unexpectedly, no significant differences between groups were observed for depression mean score: 6.6(5.2) in pwMS and 6.2(4.8) in controls and for anxiety: 5.9(4.8) and 5.0(4.2). PwMS focused on health concern more often than controls, but they respected the restrictions more easily and benefited from practical activities more than controls. Conclusion PwMS showed a proper psychological resilience in comparison with controls. These findings might guide the clinical interviews and suggest both the areas to be supported and the strengths to be promoted in pwMS.

The diabetic is most of the time admitted in emergency for acute complications. An inventory of these complications will guide promotional programs aimed at preventing the occurrence of these complications. This study was conducted with the aim of identifying acute complications and decompensation factors in diabetics admitted in emergency to the Souro Sanou University Hospital Center (CHUSS).It was an observational study, of descriptive transversal type, with prospective collection for 4 months. It concerned diabetics admitted to the medical and surgical emergency departments of the CHUSS. A total of 90 diabetics were included in the study. The average age was 58.81 ± 14.7 years. Type 2 diabetes accounted for 85.6% of cases. The diagnosis of diabetes was known in 74.4% of cases. The reasons for consultation were dominated by impaired conscientiousness and fever, 54.4% and 50% respectively. Metabolic complications were found in 44.4% of patients. They were dominated by hypoglycemia, which accounted for 55.3% of cases. Dietary error was the main decompensation factor in cases of hypoglycemia and was reported in 71.4% of cases. Metabolic complications are common in diabetics admitted in emergency at the CHUSS. Decompensation factors are mostly preventable.

Camels imported from Africa enter Egypt at Southeast borders. Movement of life animals help spreading of transboundary diseases from endemic areas to free areas. Lappet-faced vulture in Egypt territory represents highly valuable gift of nature, it is recorded in Red sea zone of Egypt. Their numbers indicate vulture breeding rate was promising for such endangered species. The Egyptian authority played a great role in protecting this land from destructive behavior against wild life. The raven accompany lappet-faced vulture, while eating together, which indicates healthy atmosphere at their habitat. This work performed while studying the epidemiology of this region and the impact of movements of live animals coming from Africa on trans-boundary diseases. Lappet-faced vultures and Raven play major role in preventing transmission of infectious agents from camel carcasses. However, Vulture has strong digestive system that kill a wide range of harmful microorganisms. Moreover, these scavenge birds are considered dead end hosts for these diseases. The study provides vivid proof of the innate intelligence that distinguishes the raven, as well as evidence that the black bird possesses a common language among themselves and between them and the Lappet-faced vulture. Lappet-faced vulture is usually nesting at acacia trees & mountains. However some acacia trees showed defected growth as a result of the strong wind, such observation is of great importance to understand geography of such habitat. Lappet-faced vulture is endangered species and need more attention and care.

Aim There is limited published data describing the characteristics of the paediatric population prescribed semi elemental formulas. This retrospective observational audit aimed to describe the characteristics of the paediatric patients who have been prescribed a hydrolysed whey protein, medium chain triglycerides (MCT) based formula, Peptamen Junior® and the nutritional outcomes. Methods A retrospective observation audit was completed on a cohort of patients that was prescribed a semi elemental formula between 2016 and 2019 from a single tertiary paediatric medical centre. Data variables were collated such as patient characteristics, indications and modalities of administration, duration and tolerance to the formula. Results Data was collated on 375 patients with a median age of 6.2 years. The main underlying medical conditions were haematological/oncology (67%), gastrointestinal disorders (10.7%) and neurological conditions (9.4%). The most common indications for use were chemotherapy related side effects (36.2%), post bone marrow transplant (25.8%) and gastrointestinal symptoms (17.9%). The formula was rarely used as a sole source of nutrition, with 88% patients requiring accompanying forms of nutrition support. The majority of orders prescribed were of standard concentration (80.8%) and tolerance was recorded in 82.8% of patients. Conclusion The semi elemental formula Peptamen Junior® appears to be well tolerated in paediatric patients with a variety of medical conditions that have complex pathologies and may have wider scope of use in a more diverse group of medical conditions than currently indicated.

Indian Agriculture needs a Strategic Shift for Improving Fertilizer Response and Overcome Sluggish Foodgrain Production

Dec 2021 DOI 10.14302/issn.2639-3166.jar-21-4018
Gupta RajCorresponding author Centre for Advancement of Sustainable Agriculture, National Agriculture Science Centre Complex, New Delhi, 110012, India

In India, loss of fertility through soil erosion is primarily a summer monsoons mediated phenomenon. Reversing the land degradation processes contribute to water availability, soil fertility maintenance, adapting to climate change and overall food security. Whereas kharif (monsoon/rainy season crop) foodgrain production largely depends on summer monsoons, the rabi season (post-rainy season/winter crop) rainfall is too little to exert a direct influence. In spite of larger acreage under kharif foodgrain crops, total fertiliser consumption during kharif and rabi seasons is comparable. Negative rainfall anomalies (deficit) adversely affected total fertiliser consumption and their use efficiency. Despite significant differences in fertiliser application rates, the response to applied fertiliser nutrients is almost similar in the two seasons. This implies that nutrient use efficiency (NUE) has a ‘manageable’ and an ‘unmanageable’ component wherein 4R practices are difficult to implement under unfavourable kharif weather conditions. Partial factor productivity of fertilizer nutrients (PFPF) has continuously declined over decades mainly because of depletion of soil organic carbon, imbalanced use of nutrients and inability to maintain soil moisture supplies. These observations plus yield-gap analysis permitted us to conclude that past trends of declining NUE can only be reversed through a shift either in sustainable land management practices or enhancing the genetic yield potential/ biomass of crop cultivars or by combining both and making kharif crop planting independent of monsoons rains through direct dry seeding.

Background Aging is said to represent a declining state that is possibly especially compromised by sleep issues, and declining melatonin levels. Aim This review examined the idea that aging can be favorably influenced in numerous ways by the addition or maintenance of adequate melatonin levels. Specifically, the impact of melatonin on skeletal muscle was the key topic of interest. Method Reviewed were peer reviewed research and review articles specifically pertaining to healthy aging, melatonin, and muscle associated observations. Results Declining melatonin levels greatly impact multiple essential body systems and tissues. Supplements or interventions that heighten melatonin presence appear to have beneficial impacts on aging in general, and muscle function and structure, in particular. Conclusion The use of melatonin early on in the aging process is likely to produce more favorable long-term outcomes than not in cases of deficiency, and should be further investigated.

The present study was initiated to improve the farm animals’ productivity through the use of medicinal plants. More specifically, to determine in female cavies the effects of aqueous extract of avocado seed powder (AEASP) on the estrous cycle, the levels of LH, estradiol and tissues (ovarian and uterine) biomarkers of oxidative stress. For the trial, 24 female cavies with regular estrous cycles were selectedamong 40 trough observation of 4 estrous cycles. They were randomly shared into 4 groups of 6 females each, comparable in term of body weight (bw) (463.60±77.69 g). They received by gavage 1 mL/kg bw of distilled water for the control and 100, 200, 400 mg/kg bw of AEASP respectively for the groups EA100, EA200 and EA400. Subsequently, 3 estrous cycles were studied every day during all the treatment period. At the end, the cavies were slaughtered at the estrus phase; blood, ovaries and uterus were collected for analysis. As result, the AEASP significantly (p<0.05) increase the duration of the estrus phase in females of group EA100, without affecting significantly the duration of the estrous cycle as referred to the control. It significantly reduce the serum level of total cholesterol and increase (p<0.05) the serum concentration of LH in cavies of group EA100 compared to the control. AEASP significantly increase the serum concentration of estradiol in all treated females as referred to the control. It significantly increase the level of malondialdehyde (MDA) in the ovaries of the females of group EA400. In the uterine tissue, superoxide dismutase (SOD) increase significantly in the cavies of group EA200 compare to the control. We can conclude that the AEASP increase the duration of the estrus phase of cavies without affecting the duration of the estrous cycle. Subsequently, it increases the serum concentration of LH and estradiol.

Background Ethiopia confirmed its 1st case of COVID-19 on Friday 13th February 2020. The burden increased dramatically by August/2020. The conditions that led to this rise were not reviewed. Objective To exploreCOVID-19 related phenomena in Ethiopia during 2019-2020. Materials and Methods Review of journals, books, and letters to editors, e-sources, news, personal experiences, observations, and communications. Results The zoonotic source of SARS- CoV-2 (Severe Acute Respiratory Distress Syndrome- Coronavirus-2) is not confirmed. The precedent events; and exact mechanism of COVID-19 is not clear. Dynamic models were required on the time line of dynamics of COVID-19; dynamics of infectiousness of COVID-19, and mechanism of transmission of COVID-19. Incubatory carriers might have been missed. Screening based on temperature had been problematic. The time spent in the development of diagnostic test for COVID-19 might have contributed to the early spread. Uninterrupted flights to China during the epidemic by Ethiopian Airlines as well as uninterrupted domestic flights; IDP (Internally Displaced People); and others put Ethiopia (and other countries) at great risk. Demographic adjustment may not be applicable for Ethiopia due to lack of census which had to be conducted every 10 year, was conducted only in 2007. This adds to the problem of error projection. The impact of HIV (Human Immuno-Deficiency Virus Disease) and war in Ethiopia before 2000 might have had affected people who would be now old age and who would be at the most risk of death. This made the impact of COVID-19 to appear low as revealed by the lower number of COVID-related deaths in Ethiopia. There were also hesitations inconsistencies in case definitions; implementations of quarantine; and burial regulations. Conclusion Even though uninhibited foreign flight to China as well as domestic flights; inconsistencies in the implementation of regulations pertaining to COVID-19 have contributed to COVID- 19 emergence in Ethiopia, the absence of census; the demographic impact of HIV and war before 2000 might have made the impact of COVID-19 to appear low as revealed by the lower number of COVID-related deaths in Ethiopia. Recommendation Accurate and current evaluation of the impact of COVID-19 in Ethiopia may require the absence of census; demographic consequences of HIV; and war before 2000 into consideration.

As peripheral branches of the mandibular nerve, the mental nerve and facial nerve communicate with each other. However, investigations have not always been described in the classic anatomical texts. It remains unknown how nerve fibers of this communicating branch converge at the micro level. Thus, the objective of the present study was to observe in detail the macro and micro levels of the communicating branch of mental and facial nerves. We used five cadavers (10 samples) to conduct experiments in anatomical practice at Tokyo Dental College. A macroscopic observation was made, and the communicating branch of the mental and facial nerves was removed as a single mass. We created serial sections of this branch using the standard method and observed communicating branches of these two nerves under microscopy. As a result, the communicating branch of the mental and facial nerves was completely fused at the perineurium level. It has been reported that the mental nerve includes a small amount of autonomic nerve fiber. As for these findings, similar findings were observed for all 5 bodies and 10 sides. Thus, we believe that autonomic nerve fibers derived from the facial nerve converge with the mental nerve via this communicating branch.

Hernández Víctor Manuel VargasCorresponding author Female Health Clinic, Mexico

Background Women play an important role in the work setting. This leads them to put off their motherhood, sometimes preventing them from getting pregnant. Delaying pregnancy face women with low ovarian response, such as in Premature Ovarian Insufficiency (POI) or Ovarian Aging (OA). There is no current treatment, although there is evidence of improving ovarian function by inyecting mesenchymal stem cells (MSC). Materials and Methods Prospective, observational study of 17 women who attended Pronatal Clinic from 2019 to 2020. Each patient was registered in Assisted Reproductive Treatment (ART) and was enrolled in ovarian treatment with an autologous adipose tissue Mesenchymal Stem Cell (AD-MSCs) protocol. Three groups were assembled: 1) Control: AMH >1.2 ng/mL, without AD-MSCs, 2) POI/OA: female infertility due to POI/OA with AMH <1.2 ng/mL and 3) Amenorrhea: female infertility due to POI/OA with amenorrhea and AMH <1.2 ng/mL. Variables: Age, weight, height, serum AMH, endometrial thickness, follicular size and number on day 2 and 11 of the menstrual cycle, oocyte number, number of blastocysts and pregnancy rate. Results Between month 2 and 5, after AD-MSCs inyection, POI/OA group showed an increase in follicle number (2 to 9) and size (13.5 to 15.5 mm) on day 11 of the menstrual cycle, which resulted in a higher number of MII oocytes (2.6 to 4.2), and an increase in number of blastocysts (0 to 3) and endometrial thickness (8.6 to 9.4). Regarding the Amenorrhea group, a reboot in menstrual cycle was observed, although no further development of blastocyst was found. Conclusion The AD-MSCs inyection directly in the ovary allowed an increase in number of blastocysts and improved pregnancy rates in POI/OA patients.

We Hypothesize that It should be intuitively inferred that the behavior of the pandemics corresponds to the prediction of the Maxwell Boltzmann distribution, which is a direct function of population density. In a higher organizational metalevel, it is analogous to the Brownian movement effect, in which the possibility of being observed is determined by the observational power of the instrument. In this case, it corresponds to the sensibility and sensitivity of the probe as well as the prevalence of the arbitrary states. The states are formally considered as a partition in probability theory; both in the Kolmogorov and frequentist approach. All these become subsumed to the Bayes theorem applied to recursive conditional probability.

Background and Purpose Providing health care is the basic right of people(1). Diagnostic radiology is one of the main procedures in health care services and proper benefiting from this technology is brought only under well planning and management(1). Supervision of the available condition and its comparison with the recommended standards is a key role in assessing assurance from the benefit of these instruments (2). Data show that more than 80% of patients referring to these hospitals need radiology image (3).Improper service causes repetition of radiography and even wrong diagnosis, as a results threatening health of the patients (3) lack of protective barrier leads to the exposure of the staff to X-ray which is obviously carcinogen us (4). It happens that the instruments are not working properly, like of symmetry in X-ray field, defects in collimators, lack of adjusting ray field and X-ray, low quality or defective developing machine, lack of proper protective barrier, using low quality film and drugs, lack of protective barrier for children, all of which cause severe hazards for the patients and staff (4). Materials and Methods The crucial aim of medical services is to provide the public with their needs which are very important. The sensitivity of such services is to such an extent that in case of lack of care, the hazards are too high. In evaluation of health services, the first thing is to evaluate the device used. Methods, efficiency, profits and their combination for prevention and eradication of diseases are also important. Therefore to gain this goal, it is necessary the obtain results comparable with recommended standards. The purpose of this study was to access the conditions of radiology units at Mazandaran University hospitals and compare them with the standards of ICRU NCRP and ICRP. Radiology unit is the most expensive section of any hospital for its instruments, manpower and space provided. In a study conducted in 51centers on radiology staff, radiography room and protective barrier, ray leakage, the outcome were 89%, 82%, 77% and 37% respectively. It was found that the condition of these centers regarding the protective barriers is very unsuitable due to unawareness of the leakage (5, 6).Considering the mentioned necessities, in this study, the condition of radiography centers affiliated to the Mazandaran University of Medical Sciences was studied for the type and the rate of problem, in order to provide a proper solving method. Results Data were collected through, observation, interviewing and filling questionnaire. Results show that, the situations of the radiology units are for from international standard, to such an extent that it is matched clout 50%. Conclusion The results showed that, none of the dark rooms are standard, and do not have proper alarm signal. In 63% of these units there no tiling system about staff protection from radiation. Defects in radiography room, protective barrier and lack looking rays were 60%, 51% and 47% respectively. Referring to the obtained data, periodic supervision, and obeying of the standards are necessary.

Background A well-functioning drug supply management is the corner stone for any meaningful health service. However, Pharmaceutical supply systems in many developing countries have severe problems, including inefficient selection, procurement and use of drugs. The magnitude and extent of the problem is huge and chronic in the Ethiopian health care system for a long time. Objective To evaluate auditable pharmaceutical transaction service process in Seka primary hospital, Jimma zone south west Ethiopia. Evaluation Methodology Case study design involving both quantitative and qualitative methods was conducted in Seka primary hospital. The focus of this evaluation was on the process of Auditable pharmaceutical transaction service. The evaluation was focused on process part of the program with dimensions; availability, compliance and client satisfaction in the dimension of accommodation. Resource inventory, document review; key informant interviews and observations were conducted. Client satisfaction was assessed through exit interview; with sample size of 326. The qualitative data was analyzed manually using thematic analysis and quantitative data were analyzed by using SPSS version 23 software. Results In Seka primary hospital, percentage availability of the 32 selected Key medicinewas 10.7(82.0%) and there were no expired drugs found on their shelves. The availability of 17 of the required 20(85%) professionals was adequate according the Auditable pharmaceutical transaction service. The average lead time was found to be less than five days. The average counselling and dispensing time were 5:43 minutes and 1:17 minutes, respectively. The average number of drugs per prescription was 2.0. The 1154(97.9%) of drugs prescribed by generic name and 1175(99.7%) of prescribed drugs on Essential Drug List indicates prescribers ‘adherence to facility specific List. Conclusion This evaluation revealed that (based on the pre-set judgment criteria) the achievement of the Auditable pharmaceutical transaction service in Seka primary Hospital was GOOD 82.6 % (achieved 355.2 of 430 weight given), i.e. even though it is Good achievement ,there are areas that needs improvement. Areas for improvement identified were: Pre- and in-service training for all health workers involved in store room and dispensary to improve on the medium counselling time, poor record keeping and the extremely poor labelingof drugs which this all improve the overall client satisfaction.

Redefining Coronavirus: Update on the Impacts of COVID-19 in the Rural Areas of Abia State

Public health professionals working in rural communities are aware of the health disparities which result from lack of physicians, limited services, and income during the pandemic. Also they are aware that some populations are more vulnerable than others. People in the rural areas are experiencing problems on their physical, social and economic life styles because the pandemic is exacerbating some inequities. Individuals especially women and children in the rural areas are facing barriers in accessing health care services due to lack of resources and availability of health care providers in the communities. With COVID-19, women are less likely to seek services, including sexual and reproductive health services. Such services may be postponed to limit exposure to COVID-19 infection. This is particularly disturbing because in addition to the women maintaining their own health, they are also responsible for taking care of the mental, emotional and physical health needs of their families as well as all domestic responsibilities. As such, women in rural settings face special challenges as a result of these significant roles they play. Therefore, the impacts of COVID-19 are exacerbated on women by virtue of their sex and the roles they play in the family. This is a qualitative study that reviewed the reports of the 36 health care professionals under the aegis of members of COVID-19 committee working in partnership with state government to control, prevent and cushion the effects of COVID-19 in the society. This study is therefore, a summary of the observations of the COVID-19 committee members made up of 10(27.8%) females and 26(72.2%) males. The study focused on exploring how individual lifestyles in the rural areas have been affected in the face of COVID- 19 pandemic by identifying the vulnerabilities in social, political and economic systems which can amplify the impacts of the pandemic. Findings showed that preventive measures like lockdown and social distancing rules, wearing of face mask, hand washing with soap, and environmental cleanliness were not observed. The study noted that health seeking behaviours, sexual and marital life including income, education, employment and social interactions were all negatively affected. Most hospitals were battered and health care professionals boycotted the hospitals for fear of being infected. It was found that lack of health workers in the hospitals caused a good number of individuals to engage in self-medications. Also most pregnant women delivered their babies at home and few with traditional birth attendants. Some of the women who had deliveries at home experienced complications during and after delivery. Unfortunately, the report showed that governments’ financial supports to these women and their family members were insignificant as the government was more concerned with mitigating the spread of COVID-19 than assisting women to have safe deliveries. Therefore, the vulnerable groups especially women, children, and the elderly who experienced threats to their safety and wellbeing as a result of the services that were disrupted during the pandemic, should be assisted so as not to lose their lives to preventable diseases.

Background Nephrotoxicity is a complication due to the effect of some toxic chemicals on kidney. Current study planned to screen the effect of Trigonella foenumaqueous seeds extracts on EDTA induced nephrotoxicity. Trigonella foenum known for its various medicinal properties is also a natural antioxidant and a free radical scavenger with no documented evidence as a nephron-protective agent. Objective To investigate the protective effects of aqueous seed extracts of Trigonella foenum. Material and Methods The present study was used 40 male albino rats (Rattus albinus) with weight of (150 ± 10) g with divided into four groups: control gp; EDTA gp (95 mg/kg); Trigonella foenum gp (500 mg/kg) and EDTA + Trigonella f oenum gp by gastric tube daily for 4 weeks. Blood urea, creatinine, GFR, creatinine clearance, MDA and GPx analyses and microscopic examination of kidney were performed. Results In the present study, Blood samples were taken from all groups and concentration of serum urea, creatinine, GFR, Creatinine clearance, MDA and GPx were determined. Histopathological observations were observed in kidney tissue. Data were analyzed using analysis of variance (ANOVA). EDTA induced an increase in urea and creatinine as well as there was a decrease in the concentration of GFR and creatinine clearance. The level of MDA was increase while the concentration of GPx was decrease in the serum of EDTA group. The aqueous extracts of Trigonella seeds significantly prevented renal damage by normalizing increased levels of renal markers. The correction of oxidative stress biomarkers was consistent with amelioration of the histopathological changes induced by EDTA. Hence, it is suggested that ameliorative effect of aqueous extract of Trigonella foenumagainst EDTA induced nephrotoxicity. Conclusion The present data suggest that aqueous extract of Trigonella foenum exhibits reno-protective effect in EDTA induced renal damage.

Background Rational drug management has become an increasingly important topic in order to make optimal use of the drug budget to offer health services of the highest possible standard. It is important that continuous assessment for rational prescribing and use of drug have to be carried. Objective of this study was to gather data on existing drug prescription and dispensing practices and to evaluate the prescribing and dispensing indicators as described by the WHO. Method Observational, cross-sectional, prospective study was designed and conducted to evaluate the performance of hospital and community pharmacies in Khartoum state, related to rational drug use and prescribing and dispensing practices during the period from November 2018 to March 2019. 297 Hospital and community pharmacies from public and private sectors were contacted for carrying out this study survey and the collected data were analysed against WHO standards for core drug use indicators. Results The average number of drugs per encounter was 3.98 drugs. Hospital pharmacies had a higher (4.18±1.516) number of drugs prescribed than community pharmacies (3.87±1.331) with significance difference between mean of two types of pharmacies (P = 0.015). The percentage of antibiotic per prescription was (53.7%). Antibiotic prescribing was much higher (54.0%) in the hospital pharmacies compared to (48.6 %) in community pharmacies. The average percentage of injections per prescription at the facilities was found to be (57.6%). The percentage of prescription with written diagnosis was (26%.0) and the percentage of prescriptions with written dose was (78%.0). The average dispensing time was (1.75) minutes, The Percentage of drugs actually dispensed was (55.99%), the average adequacy of labelling of drugs was (30.4%). Overall prescribing and dispensing indicators were higher than WHO standard. Conclusion The degree of poly pharmacy was greater than of WHO criteria. The completeness and rationality of prescription was found suboptimal and components were missed.

Glandular-cystic bladder cystitis is a rare, benign non-tumor condition, preferentially located on the area of the bladder trigone and can simulate a malignant tumor. It is a benign reactive metaplasia of the bladder submucosa, characterized by hyperplasia of the islets of Von Brunn and cystic. It is classified among reactive epithelial anomalies of the urothelium, such as islet hyperplasia of Von Brünn, cystitis, glandular cystitis, nephrogenic metaplasia and epidermoid metaplasia. It presents a clinical diagnostic challenge having the expression of a simple recurrent cystitis and misleading the radiological diagnosis evoking a malignant tumor of the bladder. Its certainty diagnosis is histological. We report the case of a 38-year-old young man who consulted for recurrent cystitis. The CT scan showed a vegetative tissue structure of the middle and left medial vesical floor, sawtooth 3 cm long axis suspecting a tumor of the bladder. The patient underwent transurethral resection of the bladder lesion. The histological and immunohistochemical examination concluded with glandular and cystic cystitis (minor form). In the light of this observation, we will discuss the diagnostic difficulties, the pathophysiological mechanisms, the radiological aspects, the anatomopathological, therapeutic features and the prognosis of this rare condition. The literature regarding this entity has been reviewed and the differential diagnosis was discussed.

A field experiment was conducted during 2017/2018 to assess the effects of Argel (Solenostemmaargel, Del. Hayne) and Nitrogen fertilizer on the performance of two Sunflower Hybrid cultivars, with the objectives to exploit an easy, economic, and accessible organic fertilizer, the Argel in the phase of the continuous increasing prices of chemical fertilizers.. This experiment was laid out on spilt-split-plot experiment in Randomized Complete Block Design (RCBD) with four replications. Observations were taken on some agronomic traits (Plant height (m), Leaf area (LA), leaf Number (NL), Leaf Area Index (LAI) and Mean Seed Weight). The results revealed that the application of Argel and Nitrogen fertilizer have significantly increased the leaf Area (F= 7.22, P < 0.001), Plant Height (F=2.68, P < 0.2001), Leaf Number (F= 3.90, P < 0.0024), Leaf Area Index (F= 3.83, P < 0.0026) and Mean Seed Weight of both Serena and Opera cultivars respectively compared to the control. However, the different treatments of Argel and Nitrogen reflected variable degree of increase for the studied parameters. The study concludes that Argel is very promising, therefore a further study with different levels of Argel including other plant parameters is recommended.

V. K AbodunrinCorresponding author Department of Anatomy and Cell Biology, Faculty of Basic Medical Sciences, Obafemi Awolowo University (OAU)

This study evaluated the effects of aluminum sulphate exposure on the histology of adrenal gland of Wistar rats. Thirty adult Wistar rats were used for this study. The Wister rats were divided into three groups; group A was the control animals and tagged C, group B animals received 10g of alum dissolved in 1000cm3 of distilled water and were tagged T1, group C animals received 50g of alum dissolved in 1000cm3of distilled water and were tagged T2, via drinking water for duration of four weeks. Twenty-four hours after the last administration, the rats were sacrificed by cervical dislocation. The adrenal gland was excised and preserved in 10 % formosaline after which it was routinely processed for hematoxylin and eosin staining (H&E). Histological observations showed normal cell distribution in the control group but treated group revealed evidences of cellular obliteration& hemorrhagic necrosis. The results obtained from this study suggest that aluminum sulphate has a damaging effect on the structure of the adrenal gland.

Mahbuba KawserCorresponding author

Aim This cross-sectional study assessed the nutritional status of ethnic reproductive women aged between 15-40 years, comprising 85 lactating women (LW) and 86 non-pregnant-non-lactating women (NPNLW) who lived in various parts of three hilly districts (Bandarban, Khagrachari and Rangamati) of the Chittagong Hill Tracts (CHTs) of Bangladesh. Materials and Method Research tool was pretested semi-structured questionnaire for this observational study. Anthropometric indices like weight, height and mid-upper-arm-circumference (MUAC) were used in assessing the nutritional status. Results Most (44.4%) of the ethnic women were Marma, followed by Chakma (39.8%), Bam (8.2%) and Tripura (5.8%). No significant (P>0.05) differences were observed in socio-economic variables between LW and NPNLW. Overall, mean age of the women was 28 (±7.2) years; mean family income was 18,822.2 (±3091) BDT and majority (86%-87%) were reported to be food secured throughout the year. Mean Dietary calorie (2631±798 kcal) intake of both groups were up to the mark according to the recommended dietary allowances (RDAs) and most (80.3%-86%) of them also possessed good nutritional knowledge. However, no significant (P>0.05) differences were observed in dietary calorie intake and nutritional knowledge score between two groups of women. Overall, most (68.4%) of the women had normal body max index (BMI kg/m2), 11.7% were found to be undernourished or thin and 19.9% were overweight. It was noticed that better nutritional status of LW and NPNLW were significantly associated with literacy (P<0.05), occupancy in household chores (P<0.05), better income (P<0.05), food security (P<0.05), recommended calorie intake level (P<0.05) and better nutritional knowledge score (P<0.05). Conclusion This study showed that vast majority of the ethnic reproductive women of CHTs are in better nutritional status with normal BMI (kg/m2) and daily calorie intake according to RDA. Most of them were food secured and their nutritional knowledge score was also up to the mark. Better socio-economic condition, nutritional knowledge and accurate calorie intake play a vital role in achieving healthy nutritional status of the two women groups of CHTs.

The Fermi-Pasta-Ulam Quantum Recurrence in The Dynamics of an Elementary Physical Vacuum Cell and The Problem of its Polarization

Feb 2020 DOI 10.14302/issn.2642-3146.jec-20-3179
A. A Berezin.Corresponding author Independent researcher, Moscow, Russia

A model of a Quantum recurrence in the dynamics of an elementary physical vacuum cell within the framework of four coupled Shrodinger equations has been suggested. The model of an elementary vacuum cell shows that a Quantum recurrence which represents the dynamics of virtual transformations in the cell, qualitatively differs from that of Poincare and the Fermi-Pasta-Ulam. Whereas these recurrences develop in time or space, the Quantum recurrence develops in a sequence of Fourier images represented by non exponentially separating functions. The sequence experiences random energy additions but no exponential separation occurs. The Quantum recurrence can be defined as the most frequent array of Fourier images that appear in a certain quantum system during a period of its observation. Different scenarios of the Fourier images sequences interpreted as bosons (electron and positron) and fermions (photons) apearing in the solutions of the model demonstrate that during some periods of its observation they become indistinguishable. The quantum dynamics of every physical vacuum cell depends on the dynamics of many other vacuum cells interacting with it, thus the quasi periodicity (during the period of observation) of the Fourier images recurrence can have infinite periods of time and space and the amplitudes of the Fourier images can vary many orders in their magnitudes. Such recurrence times does not correspond even roughly to the Poincare recurrence time of an isolated macroscopic system. It reminds the behavior of spatially coupled standard mappings with different parameters. The amount of energy in the physical vacuum is infinite but extracting a part of it and converting, it into a time-space form requires a process of periodical transfer of the reversible microscopic system dynamics into that of a macroscopic system. This process can be realized through a resonant interaction between the classical and quantum recurrences developing in these two systems. However, a technical realization of this problem is problematic.

The medial calcaneal nerve (MCN) is the first branch of the posterior tibial nerve (PTN) in the porta pedis, enervates the skin of the heel and medial side of the foot. Heel pain is a common condition encountered by physicians, and this may have a significant clinical association with the MCN’s branching pattern. This study was to identify branching pattern variations in the medial calcaneal neurovascular bundle. This study was carried out using 60lower limbs of formalin-embalmed cadavers, using the tarsal tunnel dissection method for 30right and 30 left lower limbs. The medial calcaneal neurovascular bundle course was identified by exposing the PTN and its branches from the distal end of the leg toward the plantar surface beyond its bifurcation and resecting the skin and flexor retinaculum. Many MCN branching pattern variations (specifically concerning origins, numbers, and levels of branching) were observed. In the right foot a single branch was present in 21 specimens (70%), while two branches were observed in nine specimens (30%). In the left foot, a single branch was present in 22 specimens (73.3%) and two branches were present in 8 specimens (26.7%). In this study, two branches originate from lateral planter artery is the most common observation. This study concludes that a single MCN originating from the TN is the most common variant. Two medial calcaneal arteries (MCAs) originating from the LPA is also common.

On the Role of Cholecystokinin (CCK) in Fear and Anxiety: A Review and Research Proposal

May 2019 DOI 10.14302/issn.2644-1101.jhp-19-2766
Crespi FrancescoCorresponding author Biology, CSK, Verona, Italy

Cholecystokinin (CCK) is found in high concentrations in cortical and limbic structures including the amygdala of rodents, and evidence has been gathered supporting a role for CCK in the neurobiology of anxiety. A variety of animal models have been used to study a central state of fear or anxiety, state that appears to produce a complex pattern of behaviors highly correlated with each other. It is now well established that the amygdala in particular is a critical link in the pathway through which sensory stimuli come to acquire fear evoking properties. The purpose of the proposed experiments is to study the role of the putative neurotransmitter CCK in fear and anxiety in vivo by means of a methodology coupling electrochemical and electrophysiological measurements in various brain areas. Indeed, the association of in vivo differential pulse voltammetry (DPV) with in vivo extracellular single unit recording could be able to provide concomitant physiological and neurochemical indications and to relate them to behavioral events. To further study and support the initial observations pharmacological experiments will also be performed by means of CCK receptor agonists and antagonists. This may eventually lead to development of more effective pharmacological strategies for treating clinical anxiety disorders.

Efficacy of Commercial Symbiotic Bio-Fertilizer Consortium for Mitigating the Olive Quick Decline Syndrome (OQDS)

May 2019 DOI 10.14302/issn.2639-3166.jar-19-2780
Masoero GiorgioCorresponding author Accademia di Agricoltura di Torino, Italy

The inoculation of soil with a bio-fertilizer (BF), with arbuscular mycorrhiza fungi, characterizes a Symbiotic (S) agriculture mode, aimed at promoting the yield and health of crops through modifications in the rhizosphere as well as in the plant phenotype. The main objective of this study was to reduce the incidence of Olive Quick Decline Syndrome (OQDS, involving Xylella fastidiosasubsp.pauca) that afflicts the olive groves in Apulia (Italy). Non-inoculated control (C) plants were compared with Symbiotic (S) plants inoculated with 20 kg ha-1 of Micosat F ®, through a 15 cm deep scarification, in the groves of seven farms covering an area of 27 ha. In addition to a visual observation of 484 plants, to obtain a gradation of the disease severity, some objective rapid type methods were utilized to survey the plants and soil , namely leaf pH, NIR tomoscopy of the leaves, hay-litter-bag probes coupled with NIR spectroscopy and the prediction of soil induced respiration. The fingerprinting of the S and C types of leaves and litter-bags was ascertained by means of the use of a random forest algorithm in the classification matrices. The results on the symptoms appeared variable: they were significantly mitigated in two groves out of six, but they were aggravated in one. All the rapid measurements became essentials in a “holistic” model which was able to explain over 95% of the average mitigation / null / aggravation response to BF inoculation. The holistic model gathers differential and compositional analyses of the leaf (pH, crude protein, water) and of the soil (respiration), but depends mainly on the fingerprinting of the C and S leaves and litter-bags. Two keys were identified for a successful inoculation: a high degree of variability of the soil conditions permitting hospitality for the BF with enhancement of the microbial activity in the S soil (lowering the fingerprint of the control litter-bags) and homogeneity of the leaves (with increases in the fingerprint of the S leaves treated with BF). In short, the inoculation of diseased plants with one BF consortium is far from being the ultimate remedy to mitigate OQDS in all situations. Further studies are needed, at a field level, to clarify the soil hosting capacity and to define the mycorrhizal and / or endophytic * plant * pathogen interactions, even using rapid methods.

Introduction The cardiac localization of hydatid cyst (HC) is rare and little known. It is exceptionally primary and isolated. Myocardial ischemia remains an exceptional and unusual manifestation of this localization. We report the original observation of cardiac HC revealed by acute myocardial ischemia in a young subject. Observation A 35-year-old patient with no notable pathological history was admitted to our department via the emergency room for acute anterior chest pain. The somatic examination was without abnormalities as well as the baseline biological tests. The electrocardiogram demonstrated epicardial ischemia in the infero-lateral territory without other abnormalities. The cardiac troponin I was slightly elevated (32ng/l, N<19ng/l). Subsequent controls after 30min, 60min and 180min did not show significant variations. Subsequent investigations (CT, coro-CT, coronary angiography) led to the diagnosis of intramyocardial HC of the left ventricle, with no abnormalities of the coronary arteries. After surgical excision, the evolution was favorable with normalization of the electrocardiogram and the troponin Ic. Conclusion Cardiac localization of this parasitosis is exceptional and characterized by an important clinical polymorphism making its diagnosis a real challenge. It seems useful to discuss the diagnosis of cardiac HC in front of any unexplained electrocardiogram abnormality occurring in endemic zone.

Mohamed Alsanosy RashadCorresponding author College of Medicine, Substance Abuse Research Centre, Jazan University, Jazan, Saudi Arabia

Objectives This study was designed to assess the demographic characteristics, prevalence of metabolic syndrome (MetSy) among patients with schizophrenia in Saudi Arabia. Methods This is a disease-oriented and observational study. Schizophrenia was defined by DSM-IV criteria. MetSy were assessed based on the international criteria (NCEP-ATP III and AHA/NHLB). Results 90% of the participants are without a university degree and 56.4% are single. Chronic and acute cases of schizophrenia were 95% and 5%, respectively. The treatment of schizophrenia was combination therapy and monotherapy with percentages of 56% and 44%, respectively. Systolic and diastolic blood pressures were 121.92±11.07 mmHg and 77.29±0.45 mmHg, respectively. Surprisingly, all patients have abnormal HDL. A mean waist circumference of 90.23±14.88 cm for men, and 93.38±15.28 cm for women. The analysis of 101 patients showed a prevalence of the MetSy is 15.8%. Chi-square test of independence showed lack of independency of MetSy on type of therapy. Modeling of MetSy and risk factors was also conducted. Conclusion The metabolic syndrome is greatly established among schizophrenic patients. It signifies a vital hazard for metabolic and cardiovascular ailments. Evaluation of the incidence and examining of the related threats of the metabolic syndrome should be an element of the clinical managing of patients cured with antipsychotics.

Nicosia LucaCorresponding author Division of Breast Radiology, European Institute of Oncology IRCCS, Milan, Italy, European Institute of Oncology IEO, IRCCS, Via Giuseppe Ripamonti, 435 - 20141 Milano MI, Italy

Image guided ablations might be regarded as a promising effective and safe alternative for treatment of recurrent thyroid cancer in particular in patients with high surgical risk or refusing surgery. Furthermore, image guided ablations seems to represent a promising alternative to surgery or observation for micropapillary thyroid carcinoma, with the aim of providing an effective treatment with minimal invasiveness. Further studies are necessary to confirm the role in this setting

Evaluation of the Effects of Health Impact Assessment (Hia) Practice in Monteregie

Nour KareenCorresponding author University of Sherbrooke and CISSS Montérégie-Centre

This study explores the effects of the collaborative model of health impact assessment (HIA), as deployed in Monteregie (Quebec), on the development, adoption and implementation of municipal projects that include health considerations. Nine HIA processes were studied in nine territories and 35 individuals were interviewed. Data collection was based on the six steps of contribution analysis, and included document analysis, semi-structured interviews, and on-site observations. The study design is cross-sectional design were every HIA was analysed at least six month after completion. The individuals interviewed where those implicated into the HIA process (no matter at what point of the process). No exclusion criteria were applied considering that all points of view were important for this analysis. The Contribution Analysis (CA) was used to analyze the data. The study results emerged form by the interviews, the field observations and document analysis. They showed that the HIAs had varying results. First, the actors involved acquired new knowledge. However, the HIAs had little impact in terms of increasing the municipal actors’ awareness of health issues. Rather, it helped them acquire arguments for raising awareness among and convincing their municipal council members of the merits of certain actions and their potential positive impacts on citizens’ health. In fact, the HIAs were generally undertaken by municipal actors already aware of the importance of promoting citizen health. Second, as observed in the document, in a few of the HIAs, some recommendations were integrated into planning documents, but usually, as reported by the actor, the HIA report constituted an additional planning document and was not merged with the original planning documents. Lastly, following the HIAs, document analysis and interviews showed that most of the municipal actors continued to include health considerations in their subsequent planning of public policies and projects. Prerequisites for effective HIA include the presence of municipal actors, who are aware of the importance of their role in their local population’s health, municipal policies that include health considerations, and the municipality’s active participation in the HIA process. This study sheds light on the complexity of the factors that ensure HIA impact on municipal decision making and decisions. The particularities of each HIA process play a major role.

Objective: To evaluate the efficacy and safety of a novel tomato-based food supplement on the lower urinary tract symptoms (LUTS) of patients with benign prostatic hyperplasia (BPH). Methods: Twenty patients with BPH were enrolled in this observational study. They were assigned to consume daily a sachet of Lycoprozen® (5 grams) dissolved in water for two months. Results: All patients successfully completed the Lycoprozen scheduled regimen and the IPSS (International Prostatic Symptom Score) questionnaire before and after treatment. No side effects due to treatment were noticed. In this preliminary study, we have found that Lycoprozen® significantly reduced the LUTS severity (paired t-test, two-tailed p value < 0.0001). The IPSS mean values before and after the treatment were 16.95+6.0 SD (range 31-6) and 12.2+4.9 SD (range 20-2), respectively. Conclusions: Based on these data, Lycoprozen® may represent a suitable alternative option for the treatment of symptomatic BPH patients which worth of further testing in a phase 2 prospective randomized double blind placebo controlled study. The treatment was without side effects and acceptance among patients was high.

Metal Metalloproteinase 2 is Differentially Regulated by the Interplay between Glucose and Insulin

Nov 2018
Shiau Ming-YuhCorresponding author Department of Nursing, College of Nursing, Hungkuang University, Taichung, Taiwan.

Pre-adipocytes are the precursors with the potential to make new fat cells during adipose tissue expansion. Nevertheless, the pre-adipocytes behaviors, and their possible roles in energy homeostasis have long been overlooked. Our previous study implicates that interleukin-4 (IL-4) plays a positive metabolic role by promoting insulin sensitivity and inhibiting lipid accumulation. Besides, abundant evidence shows the involvement of matrix metalloproteinase-2 (MMP-2) in the process of adipose tissue expansion. The present study aimed at examining the cross talk among glucose, insulin and IL-4 on regulating MMP-2 expression and activity in 3T3-L1 pre-adipocytes. Effects of insulin and/or IL-4 on MMP-2 expression and activity were examined in pre-adipocytes under euglycemic or hyperglycemic environment by RT-PCR and gelatin zymography, respectively. Our results revealed that glucose level is a pre-requisite for pre-adipocytes responding to insulin and/or IL-4 treatment. In high glucose-containing environment, short-term acute insulin treatment (AI) and long-term chronic insulin exposure (CI) showed opposite regulation to MMP-2 expression and activity. Interestingly, the dominant MMPs regulatory role of CI under euglycemic condition was attenuated in cells exposed to high glucose concentration. Our results suggest pre-adipocytes may participate in the process of increasing adiposity, diabetic onset and diabetic complications through ECM alterations resulted from the insulin- and/or glucose- mediated changes of MMP-2 activity. The present study uncovers novel observations regarding pre-adipocytes behaviors.

KE BonyCorresponding author Department of Neurology, University Teaching Hospital, Alassane Ouattara University, Bouake Ivory Coast.

We report the results of a two-month descriptive observational survey to assess the knowledge about epilepsy among primary school teachers in Bouake in Ivory Coast. This study included 310 teachers who were randomly chosen from three Primary School Inspections (PSI). Almost all the teachers who were included had shown inaccurate information about epilepsy. 46.45% of the respondents thought that epilepsy was contagious and 47.74% recommanded to avoid contacting with salivary secretions of the patient during seizure. For 16.45% of them, persons living with epilepsy (PWE) could be not married and 19.7% believed that PWE could not have children due to the risk of transmission. This study highlights the urgent need of awareness campaigns among primary school teachers.

Introduction: Non epileptic seizures (NES) are little reported in our country. Case report: We report 2 observations of 4 years old girls, with normal psychomotor development, and frequent paroxystic seizures, characterized by stereotyped movements of the members, occurring during sleep onset or deep sleep. Electroencephalogram Sleep records showed brief discharges of spikes and spikes-waves. Magnetic Resonance Imaging was normal. Suspicion of NES associated with epilepsy was based on the following arguments: mild regression of the seizures frequency after using antiepileptic drug video records of the seizures strongly suggestive of masturbation seizures, masturbation seizures are triggered by the girls and stopped on order, best regression of the seizures frequency after adjunction of trihexiphenidyl. Moreover, the authors make a review of literature on the NES. Conclusion: The early diagnosis of the NES allows to avoid the inadequate treatments and an improvement of the prognosis.

The Cost of Acquiring Crossveinless-Ness in Waddington’s Assimilation

Neo-Darwinian natural selection theory indicates that sudden, drastic changes in the environment place selective pressure on genetic variants in a population. As time progresses, this pressure sculpts individuals to better fit this new environment. Waddington’s classic experiment was repeated using white-eyed (the w1118strains) flies which produced the crossveinless (cve; disturbed wing crossveins) trait from the parent generation. The F1 generation was split into two selection lines: an Upward Selection Line, that produced more cve in successive generations, and a Downward Selection Line that responded with a consistent but non-linear decline in the percentage of crossveinless. This article will introduce and enlarge observations made on flies with cve; especially the manner in which the Waddington experiment impacts the population. It seems that Waddington evaluated crossveinless just by what it is good for, but not by the price of using it. That is to say, there is an inevitable cost that needs to be paid in order to acquire crossveinless-ness (cve and the associated phenotypes).

C. Jellesma FrancineCorresponding author Research Institute Child Development and Education

Within the field of school psychology there is a gap between research and practice, caused by difficulties in translating the programs from research to the realities of the school setting. Illustrations of real-life cases may help school psychologists gain insight into the application of interventions. The purpose of this study was to describe an example of small group cognitive behavior therapy in the school setting. It concerned test anxiety with extreme blushing. A single subject case study of a nine year old Dutch boy was described. Interviews, observations and questionnaires were used for evaluation, as well as a standard national achievement test. The results indicate that the test anxiety and blushing decreased and on the achievement test three years later, performance was good.  As it concerns a case study, the results are discussed tentatively. It was concluded that the intervention was successful without alterations to the program. This study provides an illustration of research put into practice.

M. Chaudhary SanjeevCorresponding author Associate Professor, Government Medical College,Gondia

Background : DOTS is the current international strategy for tuberculosis control endorsed by the World Health Organization and the International Union against Tuberculosis and Lung Diseases. Maharashtra achieved full coverage under RNTCP in October 2003. The programme was launched in Nagpur in the last quarter of 2002. Three years after its launch, it is the ideal time to assess the performance of programme to identify the operational challenges. Methods: This is a cross sectional study carried out in 'Sadar Tuberculosis Unit' of Nagpur Municipal Corporation with the objective to study performance of some aspects of RNTCP. Programme performance was explored through laboratory records review and non participant observations of all four designated microscopy centres. DOT centres were observed for accessibility, identifiability and the facilities provided to patients visiting for treatment. Performance of some operational aspects of RNTCP was assessed using standards, norms, procedures etc described in programme guidelines. Results: It was observed that the TB unit was manned with RNTCP- trained supervisory team. Three of four microscopy centres were established in multispecialty health facilities. Adequate space for sputum microscopy was available at two centres. Laboratory technician was available at three centres. Separate tables for smearing and staining were available at three centres. Sink, staining racks, spirit lamp, binocular microscope and drugs in patient - wise boxes were available in all four centres. Laboratory registers were completely and correctly filled in all centres. No false positive or false negative error was found in rereading of AFB smears. Conclusions: It is concluded that the performance of the programme at the unit is satisfactory. Still some aspects of the programme components need to be strengthened at microscopy centres for better performance of RNTCP.

El Bardai GhitaCorresponding author Nephrology department, Hassan II University Hospital, Fez, Morocco.

Introduction: Sonographic B-lines, also known as lung comets, have been shown to correlate with the presence of extravascular lung water. The aim of this study is to assess if chest ultrasound could detect lung water imbibition and its variations induced by dialysis, an experimental model of controlled rapid fluid loss. Methods: A cross-sectional study was conducted in a hemodialysis center in the city of Fez. Lung ultrasounds, impedance measurement, and ultrasound of the inferior vena cava were achieved 30-60 minutes before and after the hemodialysis session. Results: The values, measured by the different techniques used, decrease significantly after hemodialysis (p <0.001). The values studied before and after the hemodialysis, had shown a significant correlation between the results of the impedance measurement, lung ultrasound, and the maximum and minimum of the VCI index diameter and its collapsibility. The decrease in B-lines was correlated with weight decrease during dialysis (p0.005); none of the parameters concerning the IVC were correlated with fluid removal. Conclusion: ultrasound performed at the bedside is now emerging as a reliable, easy-to-apply, and safe method for measuring both lung water and intravascular overload and their decrease after dialysis even on asymptomatic patients. These observations strongly support the use of lung ultrasound in estimating volume overload and monitoring the response to therapy in hemodialysis patients.

People living with HIV (PLWH) are at risk of developing chronic lifestyle diseases such as ischaemic heart disease (IHD). Physical inactivity is a modifiable risk factor for IHD. The level of ambulation physical activity in individuals living with HIV in a South African context is unknown. The aim of this study was to assess the physical activity levels and other risk factors for IHD in PLWH on antiretroviral therapy (ARV). An observational study was conducted from October 2010 to June 2012 at an outpatient clinic in Johannesburg, South Africa. Two hundred and five individuals who were on ARV for 6-12 months were screened. Physical activity was measured with the Yamax SW200 pedometer over a seven day period. Physical activity of the sample was reduced at 7673.2 (±4017.7) steps/ day with women walking less than men 6993.3 (±3462.6) and 10076.3 (±4885.6)respectively. Body mass index was increased to 25.6 (±5.4) kg/m2 with women noted to be overweight [26.6 (±5.5) kg/m2]. Independent predictors of being overweight were systolic blood pressure, waist and hip circumference, CD4 count and daily fruit and vegetable intake. Smoking was less common in the study population with 16.1% of the sample being current smokers and 25.9% former smokers. Individuals’ mean perceived stress levels were 19.9 (±7.8) on the Cohen’s Perceived Stress Scale. The ambulation physical activity level of individuals living with HIV requires modification to assist with reducing risk factors of IHD.

Objective: We compared preoperative data of physical examination, CT and diffusion MRI findings of temporal bone with our intraoperative observations. We investigated the diagnostic efficiency of single-shot spin echo echoplanar diffusion MRI (SS SE EPI) on primary cholesteatoma. Methods: 33 patients with chronic otitis media who had been admitted to Otolaryngology Department of Haydarpasa Numune Training and Research Hospital between June 2010 and September 2011 were involved in this study. All patients did undergo otoscopic and audiometric examination. After imaging of temporal bone by CT and diffusion MRI, patients were operated and intraoperative observations were recorded. Patients with intraoperatively approved cholesteatoma were defined as group 1 and those without cholesteatoma were defined as group 2. Perioperative and preoperative findings of physical examination, CT and MRI of all patients were compared one by one. Results: Positive physical examination findings have been superior to MRI and CT, having a sensitivity of 96%, specifity of 87.5%, positive predictive value of 96% and negative predictive value of 87.5%. In terms of effectiveness of MRI in diagnosing intraoperative cholesteatoma, we had a sensitivity of 80%, specifity of 50%, positive predictive value of 83.3% and negative predictive value of 44.4%. These values are also lower than previously reported results. Conclusion: When we had preoperative suspection of cholesteatoma on physical examination and diffusion MRI, in addition with bone tissue erosion on CT, we found that physical examination is superior to MRI and CT in terms of capability of diagnosing the disease.

Branch Retinal Vein Occlusion in Factor V Leiden Mutation

Jun 2015 DOI 10.14302/issn.2470-0436.jos-14-528
Sanjay SrinivasanCorresponding author Ophthalmology and Visual Sciences, Khoo Teck Puat Hospital, Singapore

A previously healthy 25 year old Chinese male presented with left eye blurring of vision and was diagnosed to have left eye branch retinal vein occlusion. Initial blood investigations and thrombophilia screen were negative. The patient subsequently improved with observation and conservative management, with no further events over a 2 year follow up period. The blood investigations were repeated 2 years later as part of a health check-up and he was then tested to be heterozygous for the factor V leiden mutation. This was confirmed by sequencing of his genome that identified the mutation. The laboratory was contacted to provide details regarding the testing methods and was noted to have performed the two tests via different methods. While false negative rates in genetic testing are low, we believe that there is greater need to standardize testing methods as ascertaining genetic conditions play a great role in clinical diagnosis, treatment and prognosis. Clinicians should be aware of the limitations of these tests. When clinical suspicion is high, there may be a role for repeat tests with different methods or in different laboratories.

New Regulations for Foods Offered to School Children in Chile: Barriers to Implementation

Objective: To prevent childhood obesity, the Chilean government has recently implemented food regulation laws that apply to schools. This paper reviews the literature regarding the challenges in successfully integrating policies to regulate foods offered in schools. In addition, to understand some of the potential implementation barriers, a survey was conducted to evaluate how well food regulation laws were understood and implemented in Chilean schools. Methodology: A narrative literature review was conducted regarding food regulation policies in Chilean schools and potential barriers to implementation. This informed a subsequent descriptive, qualitative survey which was conducted in the Valparaíso region of Chile to examine knowledge, practices, and potential barriers to implementation of the new regulations. Twelve randomly-selected school food kiosk owners completed a survey and structured interview. Visual observations were also performed at each food kiosk. Content analysis identified trends in food items sold and determined the depth of understanding kiosk owners have of a specific new food law, "La Composición Nutricional de los Alimentos y Su Publicidad (20.606)." Key Results: 7 articles in Spanish and 10 in English were reviewed. The literature review revealed that unhealthful food options are readily available to Chilean students in school kiosks. The results of the survey and interview indicated that the school kiosk owners surveyed have a general understanding of the food law. 10 out of 12, however, were unsure of the law's exact contents. Unhealthful food options, inconsistent with regulation 20.606 were observed in all 12 visited kiosks. Conclusion: Evidence from a literature review and the survey findings confirm that unhealthful foods persist in Chilean schools, despite government food regulations. Although the majority of the school kiosk owners acknowledge law 20.606, most lack an understanding of its exact contents and their role in promoting healthier foods in schools. Further education of vendors and school administrators is needed to enhance compliance with the new Chilean food regulations.

This double-blind randomized studyevaluates the efficiency of the Quick Liberatory Rotation maneuver (QLR) in solving signs and symptoms of Posterior Canal BPPV in a short time follow-up comparing the efficiency of QLR vs. a sham maneuver (“Fake QLR”).The study was performed at an input-output tertiary center for balance disorders.From January to September 2012, 200 patients with signs and symptoms of Posterior Canal BPPV respected the inclusion criteria in the study. The diagnosis was based on observation with binocular infrared videonystagmoscopy of the paroxysmal torsional and upbeat nystagmus evoked through the Dix-Hallpike test (DHT). Patients were divided in two groups, 100 in the group treated by QLR (Group 1) and 100 in the control group treated by “Fake QLR” (Group 2). Before the treatment, they self-evaluated a Visual Analogue Score on their vertiginous complaints (V-VAS). Patients were controlled one hour after the treatment by a blinded examiner about the first phase of the study through DHT, the Straight head-hanging positioning test and the Head Roll test in supine position and assessed again with V-VAS. Patients with a persisting positive Dix- Hallpike test were subsequently treated through QLR. The main outcome measure is the number of patients treated through QLR or “Fake QLR” with a negative DHT one hour after the first treatment. At the post-procedure check, 79 patients from Group 1 presented a negative DHT with little or no subjective symptoms, whereas all the patients of Group 2 presented persistence of a positive DHT. The presence of the secondary nystagmus during QLR (“liberatory” nystagmus) was significantly correlated with a negative DHT at the post-procedure control. In Group 1 pre- and post-treatment V-VAS differences were significant; post-treatment V-VAS differences were significant in Group 1 vs. Group 2. In a short time follow-up QLRis an effective treatmentfor Posterior Canal BPPV when compared to a sham maneuver.

Investigating the Relationship between Children, Depression, and Pain in Black Women with Sickle Cell Disease (SCD)

Medical advances in obstetrics and hematology have encouraged researchers to investigate the reproductive risk in women with Sickle Cell Disease (SCD) attempting motherhood.  However, few hematological studies have been completed focused specifically on the reproductive mental health of Black women with SCD.  Historically women with SCD have been guided away from childbirth under the premise that they were not emotionally or physically capable of managing children. One question that remains unclear, from the limited research available in this area, is whether the presence of children serves to influence mood and pain in Black women with SCD.  The current study examined the effects of the presence of children on self-reported pain and depressive symptoms and the relationship between pain and psychological functioning in African American women with SCD.  Self-reported rates of depression, pain intensity, and pain severity were evaluated in 70 African American females with SCD.  Results of Analysis of Covariance (ANCOVA) did not find differences in reported mood or pain between women with and without children.  The current study serves as an initial observation upon which replication of the current findings and future prospective studies can be conducted. The study may ultimately mature into an area of research that guides reproductive decision-making for women with SCD and their doctors.

Bioinformatic Resources for Diabetic Nephropathy

Sep 2013 DOI 10.14302/issn.2374-9431.jbd-13-226
Jayne McKnight AmyCorresponding author Nephrology Research, Centre for Public Health, Queen’s University of Belfast

The number of individuals with diabetes is increasing worldwide and a large subset of those affected will develop diabetic nephropathy. Diabetic nephropathy is the leading cause of end-stage renal disease, has serious health consequences for affected individuals, and represents a major monetary cost to healthcare providers. Technological and analytical developments have enabled large-scale, collaborative studies that are revealing risk factors associated with diabetic nephropathy. However, much of the inherited predisposition and biological mechanisms underpinning risk of this disease remain to be identified. Meta-analyses and integrated pathway studies are becoming an increasingly important part of research for diabetic nephropathy including, genetic, epigenetic, transcriptomic, proteomic research, clinical observations and the development of animal models. This report highlights current bioinformatic resources and standards of reporting to maximise interdisciplinary research for diabetic nephropathy. The identification of an -Omics profile that can lead to earlier diagnosis and / or offer improved clinical evaluation of individuals with diabetes would not only provide significant health benefits to affected individuals, but may also have major utility for the efficient use of healthcare resources.

Differences in the Alveolar Macrophage Proteome in Transgenic Mice Expressing Human SP-A1 and SP-A2

Surfactant protein A (SP-A) plays a number of roles in lung host defense and innate immunity. There are two human genes, SFTPA1 and SFTPA2, and evidence indicates that the function of SP-A1 and SP-A2 proteins differ in several respects. To investigate the impact of SP-A1 and SP-A2 on the alveolar macrophage (AM) phenotype, we generated humanized transgenic (hTG) mice on the SP-A knockout (KO) background, each expressing human SP-A1 or SP-A2. Using two-dimensional difference gel electrophoresis (2D-DIGE) we studied the AM cellular proteome. We compared mouse lines expressing high levels of SP-A1, high levels of SP-A2, low levels of SP-A1, and low levels of SP-A2, with wild type (WT) and SP-A KO mice. AM from mice expressing high levels of SP-A2 were the most similar to WT mice, particularly for proteins related to actin and the cytoskeleton, as well as proteins regulated by Nrf2. The expression patterns from mouse lines expressing higher levels of the transgenes were almost the inverse of one another – the most highly expressed proteins in SP-A2 exhibited the lowest levels in the SP-A1 mice and vice versa. The mouse lines where each expressed low levels of SP-A1 or SP-A2 transgene had very similar protein expression patterns suggesting that responses to low levels of SP-A are independent of SP-A genotype, whereas the responses to higher amounts of SP-A are genotype-dependent. Together these observations indicate that in vivo exposure to SP-A1 or SP-A2 differentially affects the proteomic expression of AMs, with SP-A2 being more similar to WT.

Pattern of Use of Highly Active Antiretroviral Therapy Regimens and Pattern of Occurrence of Adverse Drug Reactions in an Indian Human Immunodeficiency Virus Positive Patients

Jun 2013 DOI 10.14302/issn.2324-7339.jcrhap-12-174
Rajesh RadhakrishnanCorresponding author Radhakrishnan Rajesh M.Pharm, Asst Professor (Senior Grade), Department of Pharmacy Practice, Manipal College of pharmaceutical Sciences, Manipal University, Manipal- 576 104, Karnataka, India.

Background: In India, Human immunodeficiency (HIV) infected patients with highly active antiretroviral therapy (HAART) are at higher risk of developing adverse drug reactions (ADRs). Objectives: The aim of this study was to characterize the pattern of use of HAART, occurrence, incidence, severity and causality of ADRs to HAART in Indian HIV positive patients. Methods: This was a prospective observational study conducted between August 2009 and May 2012. Enrolled HIV positive patients were intensively monitored for ADRs with fixed dose antiretroviral therapy as per National AIDS Control organization (NACO).World Health Organization (WHO) definition of ADR was adopted to detect ADRs to HAART and classified based on WHO adverse reaction terminologies. Naranjo’s scale was used for causality assessment of ADRs. Preventability was assessed using Thornton and Schuman criteria and severity was assessed using the modified Hart wig and Siegel scale. Pattern of ADRs was assessed with patient demographics, ADRs characteristics, and pattern of drug and reaction characteristics. P-value <0.05 was considered as statistically significant. Results: A total of 426 ADRs to HAART were evaluated from 1982 HIV positive patients during the study period. The overall incidence of ADRs to HAART was 21.4%. Significant difference was seen in the incidence of ADRs in the age group of 41-60 years (p <0.001), CD4+T-cell counts of 350-500 cells/µl (p <0.001), females (p <0.001). Three fatal ADRs of with cutaneous drug eruptions of Steven Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) was 1.1%. Anemia (31.7%) accounted for majority of the reports followed by vomiting (15.5%), skin rash (12.9%) and peripheral neuropathy (10.7%). The suspected drug was withdrawn for the management of the ADRs in majority (27.9%) of the reports. Higher incidence rate of ADRs was noted with lamivudine (3TC) + nevirapine (NVP) + stavudine (D4T) (22.9%). In, naranjo's causality assessment, majority of the ADR reports were rated as possible (69%). Symptomatic treatment for ADRs was given in 91.8% of the reports and 86.4% of the reports the patient recovered from the suspected adverse reaction at the time of evaluation. Conclusion: In India, occurrence of ADRs to HAART in HIV infected patients was found to be higher with zidovudine induced anemia (31.7%). The higher percentage of ADRs to HAART was seen with female patients, age 41-60 years; CD4+ T-cell counts 350-500 cells/µl. Physician must focus for monitoring all lab investigations for early detection and prevention of adverse effects associated with HAART.
