Assessing the knowledge, attitude, and practice of frontline physicians in Egyptian university hospitals regarding pharyngitis and acute rheumatic fever: a cross-sectional study that calls for action.

Background: Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) remain major public health issues. Although the primary and secondary prevention of RHD through appropriate management of bacterial pharyngitis and ARF are well-described in the literature, few studies address the knowledge, attitude, and practice (KAP) of developing countries. We aimed to evaluate the KAP of the frontline physicians in Egyptian university hospitals regarding pharyngitis and ARF.

Adductor canal block versus femoral nerve block for pain control after total knee arthroplasty: A systematic review and Meta-analysis.

Background: Femoral nerve block is a widely accepted nerve block method with evident reduction in consumption of opioid painkiller and minimization of the duration of hospital stay but may cause weakness of quadriceps muscle strength. Adductor canal block is another nerve block technique that attracts the attention of scientific community nowadays because of its possible superiority over Femoral nerve block regarding mobility and muscle strength.

Methods: This is a systematic review and meta-analysis of 33 studies, aiming to compare femoral nerve block with adductor canal block following total knee arthroplasty regarding pain control and mobilization.

Poor sleep quality and reduced immune function among college students: Perceived stress and depression as mediators.

Objectives: Sleep problems are highly prevalent among college students and are linked to a multitude of detrimental consequences, among which are heightened perceived stress and symptoms of depression. The present study investigated the effect of poor sleep quality on the immune function of college students. A serial mediation model was developed to test the prediction that perceived stress and depression sequentially mediate the relationship between poor sleep quality and reduced immune function among college students.

Sleep quality, stress level and COVID-19 in university students; the forgotten dimension.

Material And Methods: A questionnaire, including the Pittsburgh sleep quality index, the insomnia severity index, the perceived stress scale and COVID-19 fear index was distributed to the undergraduate students through the online platforms of South Valley University during the period of 1st to 15th June 2020.

Gettering in PolySi/SiO Passivating Contacts Enables Si-Based Tandem Solar Cells with High Thermal and Contamination Resilience.

Multijunction solar cells in a tandem configuration could further lower the costs of electricity if crystalline Si (c-Si) is used as the bottom cell. However, for direct monolithic integration on c-Si, only a restricted number of top and bottom cell architectures are compatible, due to either epitaxy or high-temperature constraints, where the interface between subcells is subject to a trade-off between transmittance, electrical interconnection, and bottom cell degradation. Using polySi/SiO passivating contacts for Si, this degradation can be largely circumvented by tuning the polySi/SiO stacks to promote gettering of contaminants admitted into the Si bottom cell during the top cell synthesis.

Knowledge, attitudes, practices and perceived barriers towards research in undergraduate medical students of six Arab countries.

Background: The involvement of the undergraduates in the research field requires a better view of their potential and the anticipated barriers facing them. This study aims to assess the undergraduates' knowledge, attitudes, practices and perceived barriers towards research in six Arab countries.

Methods: A cross sectional study included medical students from six Arab countries, where a self-administered five-section questionnaire was used to assess the students' demographics, knowledge, attitudes, practices and perceived barriers.

Mental Health, resilience, and religiosity in the elderly under COVID-19 quarantine in Qatar.

Introduction: Corona Virus Disease 2019 (COVID-19) quarantine has been associated with depression, anxiety, and stress symptoms. We hypothesize these symptoms might even be more pronounced in the elderly, who may be particularly sensitive to social isolation. However, certain individuals might be more resilient than others due to their coping mechanisms, including religious coping.

Lithium carbonate as add-on therapy to radioiodine in the treatment on hyperthyroidism: a systematic review and meta-analysis.

Background: The main purpose is to investigate the effect of LiCO3 as an add-on therapy with radioactive iodine in increasing the cure and decreasing the T4 level compared to radioactive iodine alone. The primary outcome is the cure rate as defined by the number of hyperthyroid patients who became euthyroid or hypothyroid. The secondary outcome is the T4 level.

Quality of diabetes care in patients with schizophrenia: a case-control study in Qatar.

Background: Patients with schizophrenia are at least twice as likely to develop diabetes mellitus compared to the general population. This is of significance in Qatar given the high prevalence of obesity and diabetes. Furthermore, the lifespan of people with schizophrenia is shortened by approximately 15 years, partly due to long-term microvascular and macrovascular complications.

Beta 2 Adrenergic Receptor Genetic Polymorphisms in Bronchial Asthma: Relationship to Disease Risk, Severity, and Treatment Response.

Background: The β-adrenergic receptor gene is one of the most extensively studied genes with respect to asthma prevalence and severity. The Arg16Gly and Gln27Glu polymorphisms in the β-adrenergic receptor gene cause changes in the amino acids sequence of the receptor which may cause alteration in response to bronchodilators and the risk of asthma.

Objective: The purpose of the study was to determine the association between β-adrenergic receptor gene polymorphisms and asthma risk, severity and response to therapy.

HISTOCHEMICAL EFFECTS OF SOME BIOLOGICAL AGENTS ON CULEX PIPIENS LARVAE.

The histochemical effects of the lethal concentration that kills 50% of larvae (LC50) of three biological agents, abamectin, Bacillus thuringiensis and spinosad on the carbohydrates (polysaccharides), proteins, nucleic acids and lipids content of the midgut and fat bodies of Culex pipiens 2nd instar larvae were studied. The results showed that the three tested compounds reduced the carbohydrates (polysaccharides), proteins, RNA synthesis and lipids content after 72 hours of treatment where abamectin was the most effective followed by Bacillus thuringiensis then spinosad.

Medical treatment of small abdominal aortic aneurysm.

Conventional open repair or endovascular aneurysm repair is indicated for infrarenal abdominal aortic aneurysm (AAA) when the diameter of the latter is ≥ 5.5 cm. This therapeutic strategy is based on results of randomized trials of open repair versus ultrasound surveillance of small AAA (<5.

Unusual complications of arterial closure devices: a word of warning.

The authors describe two patients who underwent transfemoral endovascular procedures followed by the use of the Angio-seal arterial percutaneous closure device. In the first patient, distal migration of the device occurred with consequent occlusion of the ipsilateral popliteal artery 2 days post procedure. In the second patient, thrombotic occlusion of the femoral artery occurred and the patient presented with acute leg ischaemia 3 weeks post procedure.

Pharmacological therapy for patients with abdominal aortic aneurysm.

Abdominal aortic aneurysm (AAA) is a common and life-threatening disease characterized by progressive dilatation and rupture, and has a mortality rate of up to 90%. Surgical repair is recommended for large aneurysms, whereas small aneurysms are managed by 'watchful waiting'. The recently introduced AAA screening programs reduce aneurysm-related mortality; however, aneurysm detection leads to psychological problems and a reduced quality of life of patients.
