Signal averaged ECG in patients with early repolarization.

Background: Early repolarization (ER) pattern is diagnosed when the J-point is elevated on the patient's electrocardiogram. The aim of this study was to evaluate signal-averaged electrocardiography (SAECG) in patients with ER pattern.

Methods: Subjects were divided into three groups: 1-patients with normal ECG pattern (control group); 2-patients with J-point elevation in the inferior leads; and 3-patients with J-point elevation in non-inferior leads.

Epidemiological features of HIV/AIDS in the Middle East and North Africa from 1990 to 2017.

The growing trend of HIV/AIDS is a major concern in the Middle East and North Africa (MENA) regions, as its incidence in the region has increased by 31% in the last decade. The study population in the countries of the MENA region included 21 countries with a population of approximately 400 million. The Global Burden of Disease database was used to calculate the number of HIV/AIDS cases.

Epidemiology of Gastric Cancer in North Africa and the Middle East from 1990 to 2017.

Introduction: Gastric cancer is the fifth most common cancer worldwide and the third cause of cancer deaths and disability-adjusted life years (DALYs) worldwide. The countries of the Middle East and North Africa are similar in many determinants of health, but there are significant differences in the incidence of gastric cancer in these countries. Therefore, the purpose of this study was to compare the burden of gastric cancer in MENA countries with appropriate policies to reduce the incidence and mortality of gastric cancer in the region.
