Peculiar clinical and diagnostic features of infective endocarditis in Yemen: Comparative analysis with a Western University Hospital.

The aim of this study was to describe the pattern, characteristics, and outcomes of infective endocarditis (IE) in Yemen and compare the results with the findings of a Western university hospital. Patients (pts) with a final diagnosis of IE observed in Al-Thawra Sanaa Cardiac Center were prospectively enrolled in 1-year time period. Clinical and diagnostic findings were compared to clinical and diagnostic data of 50 pts with IE observed at Sapienza University Hospital in Rome, Italy.

Characteristics and Risk Factors of Yemeni Patients Presenting with Myocardial Infarction with Nonobstructive Coronary Arteries (MINOCA).

Background: Myocardial infarction with non-obstructive coronary artery (MINOCA) is a syndrome, which requires both clinical documentation of ST-elevation myocardial infarction (STEMI) (abnormal cardiac biomarker, ischemic symptoms, and electrocardiography changes) and detection of nonobstructive coronary arteries. The purpose of this study is to determine the incidence of and characteristics of patients with MINOCA in the Yemeni population.

Methods: Consecutive patients admitted between January and June 2019 at Al-Thawra Hospital, Sana'a (Yemen), with STEMI diagnosis were enrolled in this study.

HIV stigma in the teaching hospitals in Sana'a, Yemen: a conflict and low-resource setting.

Background: HIV stigma undermines a person's wellbeing and quality of life and hinders HIV control efforts. This study examined the extent and drivers of HIV stigma in the teaching hospitals in Sana'a City, Yemen. The country has low HIV prevalence (4000 (2000-11,000) per 100,000) and limited HIV control funds, worsened by a long conflict and an economic crisis.

Reproductive and behavioural risk factors of low birth weight among newborns in Al Thawra Hospital, Sana'a, Yemen.

Background: Low birth weight can lead to infant death, especially during the first year of life.

Methods: We conducted an unmatched case-control study of 252 women who came for delivery at Al Thawra Hospital, Sana'a, Yemen, between August and October 2016.

Occupational Exposure to Needle Stick Injuries and Hepatitis B Vaccination Coverage Among Clinical Laboratory Staff in Sana'a, Yemen: Cross-Sectional Study.

Background: Laboratory staff handling blood or biological samples are at risk for accidental injury or exposure to blood-borne pathogens. Hepatitis B virus (HBV) vaccinations for laboratory staff can minimize these risks.

Prevalence of Trachoma in 47 Administrative Districts of Zambia: Results of 32 Population-Based Prevalence Surveys.

Purpose: A number of previous administrative-district-level baseline trachoma prevalence estimates in Zambia required verification. We used methodologies and systems for trachoma surveys considered to represent international best practice in order to generate reliable estimates of the prevalence of trachoma.

Methods: Between March 2016 and July 2017, we undertook 32 population-based prevalence surveys covering 47 administrative districts.

Progress Towards Elimination of Trachoma as a Public Health Problem in Eritrea: Results of a Systematic Review and Nine Population-based Prevalence Surveys Conducted in 2014.

Purpose: To assess Eritrea's progress towards elimination of trachoma as a public health problem, we reviewed and compiled current knowledge on the distribution and burden of trachoma in Eritrea, then undertook further population-based surveys where indicated, with support from the Global Trachoma Mapping Project (GTMP).

Methods: For the systematic review, undertaken in March 2014, we searched (1) PubMed, using the terms ((blind* or trachoma or trichiasis) AND Eritrea); (2) the online database of rapid assessments of avoidable blindness; (3) our own grey literature collections; and (4) the Global Atlas of Trachoma database. In June and July 2014, we conducted nine population-based prevalence surveys, for each of which 30 villages were systematically selected with probability proportional to population size; in each village, 30 households were systematically selected.

Prevalence of trachoma in Yemen: results of population-based prevalence surveys of 42 evaluation units in nine governorates.

Purpose: In suspected trachoma-endemic areas of Yemen, we sought to determine the prevalence of the sign trachomatous inflammation-follicular (TF) in children aged 1-9 years, and the potential individual and household risk factors for TF in that age group. We also sought to determine the prevalence of trichiasis in adults aged ≥15 years.

Methods: We conducted a cluster-sampled survey in each of 42 evaluation units (EUs) comprising 166 rural districts of nine Governorates (Adh Dhale'a, Al Hodeihah, Al Jawf, Hadramoot, Hajjah, Ibb, Lahj, Ma'rib, Taiz) using the Global Trachoma Mapping Project systems and methodologies.

Sex differences in management and outcomes of patients with atrial fibrillation in the Middle East: Gulf survey of atrial fibrillation events (Gulf SAFE).

Differences in the management of atrial fibrillation (AF) between men and women were investigated by using Gulf SAFE data in the Middle East. The study included 2,043 patients presenting with AF to emergency room (ER) were prospectively enrolled and followed for one-year. Women were older, have higher body mass index (BMI), comorbidities, and health complications than men.

Impact of Digoxin on Mortality in Patients With Atrial Fibrillation Stratified by Heart Failure: Findings From Gulf Survey of Atrial Fibrillation Events in the Middle East.

Objective: The use of digoxin in patients having atrial fibrillation (AF) with or without heart failure (HF) is not without controversy. The aim of this study was to examine the impact of digoxin therapy on mortality stratified by HF.

Methods: Gulf Survey of Atrial Fibrillation Events was a prospective, multinational, observational registry of consecutive patients with AF recruited from the emergency department of 23 hospitals in 6 countries in the Middle East.

Challenges in renal transplantation in Yemen.

Background Renal replacement therapy was first introduced in Yemen in 1978 in the form of hemodialysis. Twenty years later, the first renal transplantation was performed. Kidney transplantations were started in socially and financially challenging circumstances in Yemen in 1998.
