Impact of Previous Infection or Vaccination on Clinical Symptoms and Viral Load of Acute SARS-CoV-2 Infection
Background: SARS-CoV-2 vaccination or previous infection can induce protective immunity. This study aims to evaluate the impact on clinical symptoms and viral load during a subsequent infection. Methods: Adults with symptoms of SARS-CoV-2 infection were prospectively enrolled into a cohort study between December 2021 and May 2023 (Omicron variant). Nasal swabs were collected for quantitative…
Atrial Cardiomyopathy and Longitudinal Outcomes in the UK Biobank
Background: Atrial cardiopathy often precedes atrial fibrillation (AF) and has emerged as an independent risk factor for cardiovascular outcomes. Previous studies assessing atrial function in relation to clinical outcomes have been small, and the importance of right-sided function is largely unknown. Methods: In 51,693 UK Biobank participants with no previous history of AF, we assessed…
Suicide, unintentional poisoning mortality, and nonfatal suicide attempts after involuntary psychiatric hospitalization
Little is known about the incidence of adverse outcomes after involuntary psychiatric hospitalization (IPH) in the United States. The objectives of this study were to use nonparametric competing risks analysis to estimate the incidences of suicide mortality, unintentional poisoning mortality, and nonfatal suicide attempt following discharge from IPH; to determine the most common methods of…
Per- and Polyfluoroalkyl Substance (PFAS) Levels in Drinking Water and Their Association with Cancer in Canines: Implications of Canines as Human Sentinels
Per- and polyfluoroalkyl substances (PFAS), known as “forever chemicals” are a range of widely used, human-synthesized chemical compounds applied in numerous capacities across the globe including food packaging, firefighting, and manufacturing products with non-stick or water-resistant properties. PFAS exposure from point-source occupational and industrial contamination has been linked to several types of human cancers including…
Impact of Menopausal Status on HPV Detection and Cervical Neoplasia in Senegalese Women
Hormonal and immunologic changes related to menopause may play a role in the detection of human papillomavirus (HPV) and cervical neoplasia, yet this relationship has not been examined in populations in West Africa, where cervical cancer remains a leading cause of cancer-related death. The purpose of this study was to assess whether menopausal status is…
Associations Between Vaginal Microbiota and Sexual Activity in Kenyan Adolescent Girls: A Focus on Lactobacillus and Limosilactobacillus Species
Background: The vaginal microbiota is a key component of genital and reproductive health. Sexual activity can influence the dominant microbes present, shifting away from colonization with key protective bacteria. This study characterized the relationship between vaginal Lactobacillus and Limosilactobacillus species and history of sexual activity. Methods: This cross-sectional study used data collected at the baseline…
Can Sidewalk and Crosswalk Availability Strengthen Association Between Physical Activity and National Walkability Index
The majority of U.S. adults do not meet the recommended amount of weekly physical activity. Urban design researchers have studied micro and macro scale features to understand if physical activity, mainly walking, can be bolstered with different initiatives. These studies have resulted in mixed findings. We used a large cross-sectional sample spanning the U.S. from…
Estimating the seroprevalence of HTLV-1 in pregnant Peruvian women based on blood bank markers: a road to elimination of mother-to-child transmission of HTLV-1 in Peru
Background: Data regarding the burden of human T-cell lymphotropic virus type 1 (HTLV-1) in pregnant Peruvian women is scarce, thus the impact of potential preventive interventions is largely unknown. Our primary aim was to estimate the prevalence of HTLV-1 in pregnant women in Peru at national and departmental levels using governmental-issued blood bank data. In…
