Background: Visceral adipose tissue (VAT) may causally contribute to cardiovascular disease (CVD); however, evidence in Latin America is limited. Here, we evaluated the association between estimated VAT (eVAT) and incident CVD among individuals without diabetes and estimated its population-attributable fraction (PAF) using data from the Cohorts Consortium of Latin America and the Caribbean (CC-LAC).

Methods: We pooled data from 15 prospective cohorts across 7 countries (n = 23,097; 62% women [n = 14,383], median age 51 years). Baseline eVAT (in grams [g]) was estimated using the Metabolic Score for Visceral Fat (METS-VF) index, incorporating age, sex, an insulin resistance index, …

Frailty As A Framework To Understand Tuberculosis Severity, Recovery, And Sequelae, Yoscelina Estrella Martinez-Lopez, Benjamin W. Black, Jessica Lee, Brian J. Buta, Lisa Y. Armitige, William A. Fountain, Rafael Samper, Aanand D. Naik, Joanne Turner, Blanca I. Restrepo

School of Medicine Publications

Tuberculosis (TB) causes profound systemic illness, and many survivors experience long-term sequelae associated with disability and premature mortality. Current TB severity indicators capture isolated aspects of disease and may not reflect the integrated physiological impact of infection on the host. Frailty, a multidimensional syndrome characterized by reduced physiological reserve and increased vulnerability to stressors, predicts adverse outcomes and guides clinical management in geriatrics. We propose frailty as an integrative framework for understanding the systemic effects of TB across the life course, encompassing disease severity, recovery, and long-term sequelae. We discuss biological mechanisms through which Mycobacterium tuberculosis infection may erode physiological …

Epidemiology, Presentation, And Diagnosis Of Type 2 Diabetes Mellitus In Children And Adolescents, Bisher Alsabbagh, Whard Alsabbagh

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

The prevalence of type 2 diabetes mellitus (T2DM) in children and adolescents has increased substantially over recent decades, paralleling rising rates of pediatric obesity and metabolic risk. Youth-onset T2DM is characterized by significant insulin resistance accompanied by an inadequate compensatory insulin response, resulting in progressive hyperglycemia and early beta-cell dysfunction. Incidence varies widely among racial and ethnic groups, with the highest rates observed in non-Hispanic Black, Hispanic, Native American, Asian American, and Pacific Islander youth. Risk factors include obesity, family history, high-risk ethnicity, pubertal insulin resistance, prenatal metabolic exposures, and comorbid conditions such as polycystic ovary syndrome. Clinical presentation ranges …

Patterns And Outcomes In Urotrauma: An Analysis Of Fatality Trends And Contributing Factors, Neharika Penmetcha, Aun Bangash, Kelsey Baker

Research Symposium

Background: Urotrauma, involving injuries to the kidneys, ureters, and bladder, represents a critical subset of trauma cases, significantly impacting patient morbidity and mortality. Renal and urogenital injuries account for 10–20% of abdominal trauma in adults and children. Understanding urotrauma's epidemiology is vital for improving care protocols and resource allocation. Despite its impact, data on injury mechanisms, intent, and care modalities specific to urotrauma remain limited. This study investigates patterns in injury mechanisms, intent, transport modalities, and facility transfer status to identify factors influencing patient outcomes and inform trauma care improvements.

Methods: A retrospective review analyzed 3,492 trauma cases, filtered for …

The Increasing Prevalence Of Cleft Lip With Or Without Cleft Palate In The Rio Grande Valley Of Texas, Yossef Alsabawi, Aaron I. Dadzie, Tyler Torres, Elias Arellano, Paul A. Berry

Research Symposium

Background: Orofacial clefts are a subset of birth defects that include cleft lip with or without cleft palate (CLP) and cleft palate alone (CP). The treatment for orofacial clefts is surgical repair, ideally within the first six months of life. Their impacts on patients and families are various and substantial. Babies with orofacial clefts can have trouble with breastfeeding, speech, recurrent ear infections, and hearing loss as they age. Additionally, there is a significant economic burden, with the average repair costing nearly $20,000, not including the costs of medical devices, postoperative care, and rehabilitation. Additionally, children with orofacial clefts face …

Malignant Colorectal Cancer In The Rio Grande Valley: A Demographical Study, Kevin M. Camstra, Vijian Dhevan

Research Symposium

Background: There is abundant demographical data available that provides an excellent general statistical overview of colorectal cancer (CRC) within the Hispanic population in South Texas. Much is known about the overarching trends regarding incidence, prevalence, mortality and screening rates among this specific population as compared to other racial and ethnic groups at the state and national levels. Despite our understanding of these broad trends, few studies have taken a step inward to provide a closer demographical analysis of a CRC population here in the Rio Grande Valley. In this study, we narrow the scope and take a closer look …

Characterization Of Prostate Cancer In Transgender Women, Simita Gaglani, Rajveer Purohit, Ashutosh Tewari, Dara Lundon, Natasha Kyprianou

Research Symposium

Background: The risk of developing prostate cancer (PC) in transgender women is unknown. Many patients are unaware that the prostate is not removed during male-to-female surgical transition. It is unclear what the exposure of estrogens and androgen blockers in these transgender patients has on the prostate. Our aim was to examine and characterize the different presentations of PC in published cases and augment this with an additional case series from one institute.

Methods: A retrospective review of prospectively maintained medical records was performed identifying features of PC diagnoses in transgender women. These included age, duration of feminizing hormone therapy, PSA …
