Background. Aging increases the risk of tuberculosis (TB) and its adverse outcomes, but most studies are based on secondary analyses, and few are in Hispanics. Diabetes is a risk factor for TB in adults, but its contribution in the elderly is unknown. We aimed to identify the role of diabetes and other risk factors for TB in elderly Hispanics.

Methods. Cross-sectional study among newly-diagnosed TB patients, recent contacts (ReC), or community controls (CoC) totaling 646 participants, including 183 elderly (>60 years; 43 TB, 80 ReC, 60 CoC) and 463 adults (18 to 50 years; 80 TB, 301 …

The genetic determinants of fasting glucose (FG) and fasting insulin (FI) have been studied mostly through genome arrays, resulting in over 100 associated variants. We extended this work with high-coverage whole genome sequencing analyses from fifteen cohorts in NHLBI’s Trans-Omics for Precision Medicine (TOPMed) program. Over 23,000 non-diabetic individuals from five race-ethnicities/populations (African, Asian, European, Hispanic and Samoan) were included. Eight variants were significantly associated with FG or FI across previously identified regions MTNR1B, G6PC2, GCK, GCKR and FOXA2. We additionally characterize suggestive associations with FG or FI near previously identified SLC30A8, TCF7L2, and ADCY5 regions as well …

Diabetes Mellitus Correlates With Increased Biological Age As Indicated By Clinical Biomarkers, Nadine Bahour, Briana Cortez, Hui Pan, Hetal Shah, Alessandro Doria, Cristina Aguayo‑Mazzucato

School of Medicine Publications and Presentations

Chronological age (CA) is determined by time of birth, whereas biological age (BA) is based on changes on a cellular level and strongly correlates with morbidity, mortality, and longevity. Type 2 diabetes (T2D) associates with increased morbidity and mortality; thus, we hypothesized that BA would be increased and calculated it from biomarkers collected at routine clinical visits. Deidentified data was obtained from three cohorts of patients (20-80 years old)-T2D, type 1 diabetes (T1D), and prediabetes-and compared to gender- and age-matched non-diabetics. Eight clinical biomarkers that correlated with CA in people without diabetes were used to calculate BA using the Klemera …

Retrospective Study Examining Obesity Hypoventilation Syndrome In Covid+ Patients, Lily Chen, Areeb Masood, Ayman Khaddam, Alyssa Chen, Ildiko Lingvay, Henry Kwang

MEDI 9331 Scholarly Activities Clinical Years

Purpose: Coronavirus disease 2019 (COVID-19) has affected millions of people all over the world with worse proven outcomes in those with certain comorbid conditions, such as diabetes, cardiovascular disease, and pulmonary complications. The Rio Grande Valley located in South Texas with a largely Hispanic population has been hit especially hard during this pandemic with over 3,200 virus-related deaths. This region’s high population of diabetic and obese patients is likely correlated with the especially high mortality rate. While it is understood the impact that obesity has on worsening health outcomes, further research is needed to better understand whether more adverse COVID-19 …

The Increase Of Hiv-1 Infection, Neurocognitive Impairment, And Type 2 Diabetes In The Rio Grande Valley, Roberto De La Garza, Hansapani Rodrigo, Francisco Fernandez, Upal Roy

Health & Biomedical Sciences Faculty Publications and Presentations

The Human Immunodeficiency Virus (HIV-1) infection remains a persistent predicament for the State of Texas, ranking seventh among the most documented HIV cases in the United States. In this regard, the Rio Grande Valley (RGV) in South Texas is considered as one of the least investigated areas of the state with respect to HIV infection and HIV associated comorbidities. Considering the 115% increase in average HIV incidence rates per 100,000 within the RGV from 2007-2015, it is worth characterizing this population with respect to their HIV-1 infection, HIV-1 Associated Neurocognitive Disorders (HAND), and the association of treatment with combined antiretroviral …

Observing Growth Effects Of Pigment Epithelium-Derived Factor On Human Retinal Pericytes In Vitro, Anjalee Choudhury, Andrew Tsin, Zachary Perez, Fransisco Elisarraras

School of Medicine Publications and Presentations

The purpose of this study is to investigate and determine the role of PEDF in the pathogenesis of diabetic retinopathy as induced by advanced glycation end-products (AGEs). Human retinal pericytes were isolated from donors and will be measured for cell proliferation under the influence of PEDF both in the presence and absence of AGEs. Expected outcomes involve both the maintenance and increased survival of HRPs after treatment with PEDF under stimulated hyperglycemic conditions.

Type 2 diabetes (T2D) is a prevalent risk factor for tuberculosis (TB), but most studies on TB-T2D have focused on TB patients, been limited to one community, and shown a variable impact of T2D on TB risk or treatment outcomes. We conducted a cross-sectional assessment of sociodemographic and metabolic factors in adult TB contacts with T2D (versus no T2D), from the Texas-Mexico border to study Hispanics, and in Cape Town to study South African Coloured ethnicities. The prevalence of T2D was 30.2% in Texas-Mexico and 17.4% in South Africa, with new diagnosis in 34.4% and 43.9%, respectively. Contacts with T2D …

Transition From Pre-Diabetes To Diabetes And Predictors Of Risk In Mexican-Americans, Shenghui Wu, Joseph B. Mccormick, Joanne E. Curran, Susan P. Fisher-Hoch

School of Medicine Publications and Presentations

Background: No studies have examined risk factors for the transition from pre-diabetes to diabetes in populations with widespread obesity and diabetes. We determined proximal changes and factors affecting the transition among Mexican-Americans with pre-diabetes.

Methods: Participants with pre-diabetes (n=285) were recruited from our randomly sampled population-based Cameron County Hispanic Cohort. These participants were followed for an average of 27 months with repeat examination every 3 to 4 months. Metabolic health was defined as having less than 2 metabolic abnormalities (e.g., hypertension, elevated low-density lipoprotein, etc). Diabetes was identified as fasting blood glucose ≥126 mg/dL, glycated hemoglobin ≥6.5% and/or on hypoglycemic …

Quality Of Life And Depression Among Patients With Type I Diabetes: A Study Of Gender Differences, Eisha Gohil, Ruby Charak, Haroon Rashid, Priyanka Sharma

Psychological Science Faculty Publications and Presentations

Diabetes is a progressive chronic condition which places a significant burden of self management on the individual, such as daily monitoring and medications management, worry about the future and distress about the impact of diabetes on various aspects of life. It is a group of metabolic diseases characterized by elevated blood glucose levels (hyperglycemia) resulting from defects in insulin secretion, insulin action or both. The present study aimed to assess gender differences in quality of life and depression in patients suffering from type I diabetes. A sample of 70 participants (44 male and 26 female) in the age range of …

Background: Detection of type 2 diabetes (T2D) is routinely based on the presence of dysglycemia. Although disturbed lipid metabolism is a hallmark of T2D, the potential of plasma lipidomics as a biomarker of future T2D is unknown. Our objective was to develop and validate a plasma lipidomic risk score (LRS) as a biomarker of future type 2 diabetes and to evaluate its cost-effectiveness for T2D screening.

Methods: Plasma LRS, based on significantly associated lipid species from an array of 319 lipid species, was developed in a cohort of initially T2D-free individuals from the San Antonio Family Heart Study (SAFHS). The …
