Article Synopsis
  • COVID-19 poses a significant global threat, and serological surveys are essential to accurately measure how many individuals have developed antibodies to the virus, revealing the true infection rates in populations.
  • A study conducted between July and October 2020 in Saudi Arabia tested 15,873 serum samples to determine the seroprevalence of SARS-CoV-2, finding an overall rate of 17%, with the Makkah region having the highest rate at 33.3%.
  • The study identified several factors influencing seropositivity, including age, education, and region, while underscoring the need for mass vaccination efforts as most people lacked SARS-CoV-2 specific antibodies, indicating low herd immunity.*

Article Synopsis
  • - The study investigates how sociodemographic factors relate to injury-related health outcomes worldwide, specifically analyzing disability-adjusted life years (DALYs) from injuries across 195 countries from 1990 to 2017.
  • - Findings show that while most injury causes display a trend of decreasing DALY rates with higher Socio-demographic Index (SDI), certain injuries like road injuries, interpersonal violence, and self-harm deviate from this trend, indicating complex underlying factors.
  • - The research highlights the importance of understanding these injury patterns to improve health strategies and intervention efforts at both national and global levels, especially since not all injuries follow the same developmental trajectory.

Background: One of the major risk factors for cardiovascular diseases is hyperlipidemia. The primary aim of this study was to estimate the proportion of individuals between 40-75 years old that would be eligible for statin therapy based on ACC/AHA guideline as compared to ATP-III guideline in a population of patients in Saudi Arabia. We also intended to extrapolate the results to the entire Saudi population, and estimate the cost implications of the ACC/AHA treatment guideline.
