Background: IOM piloted the use of Ag RDTs for COVID-19 in Iraq, in collaboration with FIND, the Global Alliance for Diagnostics, to facilitate access to testing and understand barriers and opportunities for testing in a displacement context. The purpose was to (i) evaluate the performance metrics of the Sure Status COVID-19 Antigen Card Test in this population; (ii) compare Ag RDT results across high- and low-probability cases, vaccination status, and symptom severity; and (iii) report participant perspectives on Ag RDT use for COVID-19 and other diseases.

Methods: Secondary analysis was conducted using de-identified cross-sectional data collected from November 2022-March 2023 in four IDP camps in the Kurdistan region of Iraq.

Objective: Stroke patients with large core infarctions benefit from endovascular intervention, though only approximately 20% are functionally independent at 90 days. We studied prognostic factors for patients presenting with a large computed tomography perfusion (CTP) core.

Methods: Retrospective analysis from a health system stroke registry, including consecutive thrombectomy patients treated within 24 hours from August 2020-December 2022 with an anterior circulation large vessel occlusion and CTP core infarct ≥50 milliliters.

Health system resilience is a prerequisite for effectively managing cataclysmic events adversely affecting health outcomes. The COVID-19 pandemic reasserted the importance of having resilient health systems and called for a relook at the existing framework that measures health system resilience. Mixed methods were used in this study.

Article Synopsis
  • Aging is a key risk factor for heart disease, but research shows that the right ventricle (RV) ages differently than the left ventricle (LV), with unique structural and functional changes.
  • Researchers conducted a study using RNA sequencing to explore these differences in RV and LV from young and aged mice, revealing that while the LV typically experiences concentric remodeling and diastolic dysfunction, the aging RV shows eccentric remodeling, dilation, and impaired systolic function.
  • The study identified unique molecular mechanisms of RV aging, highlighting specific genes and pathways that could guide future therapies, emphasizing the need for treatment approaches tailored to the distinct aging processes of the RV and LV.

Introduction: The National AIDS Program in Jordan has faced numerous challenges, including insufficient funding, limited resources, and complexities brought on by refugee influxes. The absence of a reliable HIV/AIDS surveillance system further complicates tracking and responding to the epidemic. This study aimed to evaluate the performance and functionality of the National AIDS Program and the HIV/AIDS surveillance system.
