The National Burden of Influenza-Associated Respiratory Illness Across Levels of Severity in Egypt, 2016-2019.

Introduction: Influenza burden (IB) estimates are crucial for monitoring disease trends, allocating limited resources, and promoting influenza vaccination. However, IB in Egypt is poorly understood. This study estimates the mean-seasonal IB in Egypt, across levels of severity by age and regions using sentinel surveillance data between 2016 and 2019.

Efficacy of vitamin D supplementation on the incidence of preeclampsia: a systematic review and meta-analysis.

Background: Preeclampsia is a severe pregnancy complication affecting 2-8% of pregnancies globally, contributing to substantial maternal and fetal morbidity and mortality. Vitamin D deficiency has been associated with an increased risk of preeclampsia, yet the efficacy of its supplementation during pregnancy in reducing preeclampsia incidence remains uncertain.

Objectives: This systematic review and meta-analysis aimed to evaluate the impact of vitamin D supplementation on the incidence of preeclampsia and related maternal and neonatal outcomes.

Sleep Quality and Its Contributing Factors Among Patients With Obesity: A Cross-Sectional Study.

Background:  Obesity is a major public health issue associated with a range of comorbid conditions, including sleep disturbances. Poor sleep quality is common in individuals with obesity, yet the factors contributing to this relationship remain underexplored, especially in non-Western populations. This study aimed to investigate sleep quality and its contributing factors among patients with obesity in the eastern region of Saudi Arabia.

Interobserver reliability and accuracy of the visual assessment of interventricular septal flattening in pulmonary hypertension.

Background: Interventricular septal (IVS) flattening is a key echocardiographic feature of pulmonary hypertension (PH) that is associated with worse outcomes. The accuracy and interobserver reliability of visual and quantitative measures of IVS in PH patients are poorly described.

Methods: This single-center, retrospective analysis included 173 PH patients.

Relationship between homocysteine, vitamin B9, vitamin B12 levels methylenetetrahydrofolate reductase (C677T, A1298C) polymorphisms, and cryptogenic stroke in Tunisian adults´ patients: a case-control study.

Introduction: the relationship between elevated plasma homocysteine (Hcy) and stroke has been established, but this association remains indistinct in cryptogenic stroke in adults. Our aim is to investigate the association between homocysteine, vitamins B9 and B12, and cryptogenic stroke. Furthermore, to determine the correlation between methylenetetrahydrofolate reductase (MTHFR) polymorphism and biochemical levels in plasma.
