Evaluating the association of prenatal PrEP exposure with perinatal and growth outcomes from infancy through early childhood
As pre-exposure prophlaxis (PrEP) implementation continues to scale-up among pregnant populations, accruing safety data following prenatal PrEP exposure remains important. Methods Data from the PrEP Implementation for Mothers in Antenatal Care study (NCT03070600) was analyzed to evaluate the relationship between prenatal PrEP exposure and birth and infant/child outcomes. Women enrolled during pregnancy at 20 maternal…
Did California’s 2020 Medi-Cal Expansion Improve Health Insurance Coverage and Mental Health Outcomes Among Young Adults Without US Citizenship? A Population-based, Quasi-Experimental Study
In 2020, California became one of the first states to expand Medicaid (Medi-Cal) to low-income young adults, irrespective of US citizenship. The primary aim of this study was to assess whether California’s 2020 Young Adult Medi-Cal expansion improved healthcare access and mental health outcomes among low-income (<200% Federal Poverty Line) young adults aged 18-25 who…
Relationship between bacterial diversity, specific urethral bacteria and incident NGU in men who have sex with women
Nongonococcal urethritis (NGU) is a common syndrome in men that is not well understood. Prior studies have investigated factors associated with prevalent NGU, but factors associated with incident NGU have rarely been examined. We evaluated potential precursors of incident NGU in a group of men who have sex with women (MSW) attending a sexual health…
Association of Patient Characteristics with Risk of Rheumatic Heart Disease in First-Degree Relatives of Index Cases in Nepal
Rheumatic heart disease (RHD) is associated with significant morbidity and mortality, particularly in low- and middle-income countries. First-degree relatives (FDR) of RHD patients share known risk factors for RHD: poverty, poor living conditions, crowding, poor hygiene, and potential shared genetic characteristics that lead to higher RHD risk. We sought to determine whether FDR screening would…
Prioritizing Out-of-Care Case Investigations in King County, Washington
Health departments need to investigate cases of people with HIV who appear to be out of care but often have insufficient resources to investigate all cases and need a way to prioritize investigations. Methods: In this retrospective cohort analysis, we used classification and regression tree (CART) methodology to develop and validate a decision algorithm for…
Can Artificial Intelligence based Automated CT Brain Interpretation Software help Early Clinical Decision Making for Stroke Patients in Real World Resource Limited Settings with Non-Specialist Physicians? An Interrupted Time Series Study from Tezpur, Assam, India
We evaluated the impact of an AI (Artificial Intelligence) based software for automated interpretation of CT brain through a retrospective interrupted time series study at a rural hospital in Tezpur, India, that is managed by non-specialist physicians and supported by teleradiology services. We compared the diagnostic accuracy of the software to detect an abnormality against…
Association between environmental modifiable risk score and molecular subtypes in colorectal cancer patients
Colorectal cancer (CRC) is associated with several modifiable environmental risks, including dietary and non-dietary factors like calcium intake and smoking habits. It is unknown if the association between overall environmental risk and CRC is differentially associated with certain molecular subtypes.Methods: A total of 6389 cases and 6835 controls of European ancestry from 11 observational studies…

Does Racial Residential Segregation Influence Smoking Behaviors? The Multi-Ethnic Study of Atherosclerosis
Tobacco cigarette smoking remains the leading cause of preventable morbidity and mortality in the United States. Racial residential segregation (RRS) in American cities may be contributing to high rates of smoking in some communities. Yet, limited research exists investigating the association between segregation and smoking behaviors. The aim of this study was to examine the…
The role of multivitamins: an investigation into the association with colorectal cancer survival
Nutritional supplements are used by over half of United States adults, and many patients use supplements for their perceived anti-cancer benefit. Current evidence for the relationship between multivitamin use and colorectal cancer (CRC) survival is sparse. Some studies suggest that multivitamins may divert attention from healthful food-based diets or multivitamin use may be reflected in…
