Hypertension, type 2 diabetes (T2D), and obesity raise an individual's risk of suffering from diseases associated with metabolic syndrome (MS). In humans, enzymes that play a role in the prevention and development of MS include angiotensin converting enzyme (ACE-1) associated with hypertension, α-amylase associated with T2D, and lipase linked to the development of obesity. Seaweeds are a rich source of bioactives consisting of proteins/peptides, polysaccharides, and lipids.

Background: Meal variety promotes overconsumption by delaying sensory-specific-satiety (SSS), the transient reduction in reward value of a recently consumed food. Despite its role in meal cessation, the neuroendocrine mechanisms underlying SSS are largely unknown.

Methods: Here, we developed a preclinical model of SSS wherein rats consume more of a different food compared to the same food presented again, leading to greater caloric intake.

Background: There is increasing need for effective incorporation of high-dimensional genetics data from individuals with varied ancestry in genome-wide association (GWAS) analyses. Classically, multi-ancestry GWAS analyses are performed using statistical meta-analysis to combine results conducted within homogeneous ancestry groups. The emergence of cosmopolitan reference panels makes collective preprocessing of GWAS data possible, but impact on downstream GWAS results in a mega-analysis framework merits investigation.

Introduction: Total pelvic exenteration (TPE) for clinical T4b colorectal cancer (CRC) is associated with significant morbidity. Short (0-30 days)- and intermediate (31-90 days)-term temporal analysis of complication onset is not well described, yet needed, to better counsel patients considering TPE.

Methods: A retrospective cohort study of consecutive patients with primary or recurrent clinical T4b pelvic CRC undergoing open TPE between 2014 and 2023 was conducted.

Background: Although highly prevalent, most perinatal mental health and substance use disorders often go unrecognized, undiagnosed, and untreated. Perinatal Psychiatry Access Programs have emerged as a successful model to increase the capacity of front-line maternal health care providers to address perinatal mental health conditions through education, consultation, and increased resources and referrals.

Methods: This model has been adapted in South Carolina to include direct access to mental health treatment in response to inadequate maternity care and mental health services, including a large proportion of rural, Medically Underserved Areas in Primary Care and Mental Health Healthcare Provider Shortage Areas throughout the state.
