Background: Accurate mortality estimates help quantify and memorialise the impact of war. We used multiple data sources to estimate deaths due to traumatic injury in the Gaza Strip between Oct 7, 2023, and June 30, 2024.
Methods: We used a three-list capture-recapture analysis using data from Palestinian Ministry of Health (MoH) hospital lists, an MoH online survey, and social media obituaries.
Background: Emergency medicine physicians must rapidly obtain and interpret an electrocardiogram (ECG) to quickly identify life-threatening cardiac emergencies such as ST-elevation myocardial infarction (STEMI). Although ECG interpretation is a critical component of residency education, few high-powered studies exploring the accuracy of resident ECG interpretation exist.
Objectives: This study aims to evaluate whether or not the inclusion of Third Year Emergency Medicine Resident ECG interpretations is noninferior to attending-only ECG interpretations in regard to time to STEMI activation.
Background: Arabic-speaking refugees are the largest group of refugees arriving in the United States since 2008, yet little is known about their rates of healthcare access, utilization, and satisfaction after the end of the Refugee Medical Assistance (RMA) period.
Methods: This study was a cross-sectional observational study. From January to December 2019, a household survey was conducted of newly arrived Arabic-speaking refugees in Connecticut between 2016 and 2018.
Puberty is a critical period of development characterized by significant brain remodeling and increased vulnerability to immune challenges. Exposure to an immune challenge such as LPS during puberty can result in inflammation and gut dysbiosis which may lead to altered brain functioning and psychiatric illnesses later in life. However, treatment with probiotics during puberty has been found to mitigate LPS-induced peripheral and central inflammation, prevent LPS-induced changes to the gut microbiota and protect against enduring behavioural disorders in a sex-specific manner.

Exposure to stress, and especially immune challenge, during this period triggers changes in brain function resulting in the development of mental disorders in adulthood, such as depression and anxiety. Previous studies from our laboratory have shown that a single exposure to LPS (lipopolysaccharide) during puberty causes enduring depression-like behaviour in females and anxiety-like behaviours in males.

Physiologic features of the host (carrying capacity) and the fitness of the gut microbiota shape microbiota density. Therapeutic manipulation of microbiota density in mice altered host metabolic and immune homeostasis.
View Article and Find Full Text PDFPurpose: Health disparities related to breast and cervical cancer among African American and African-born Muslim women in the United States have been identified in previous literature. Our study aimed at exploring the breast and cervical screening rates and factors that influence this population's disposition to adhere to cancer screening exams.
Methods: Mixed methods were used to collect data with African American and African-born Muslim women in New York City.
