Neighbourhood Social Vulnerability And Preterm Birth Risk Among Infants With Trisomy 21: A Statewide Analysis, Fatima R Sheriff, Renata H Benjamin, Qian Xiao, Jenil Patel, Charles Shumate, Alejandra Fernandez, A J Agopian

Faculty, Staff and Student Publications

Background: Residing in socioeconomically vulnerable areas is known to be associated with increased preterm birth (PTB) risk in the general population. However, the relationship between social vulnerability and PTB remains unexplored among infants with trisomy 21, who experience more than twice the PTB rate of the general population.

Objectives: The primary objective was to examine the association between maternal socioeconomic vulnerability, as measured by the SVI, and PTB among infants with trisomy 21.

Methods: We conducted a retrospective cohort study among infants with trisomy 21 born in Texas (1999-2018). We examined the association between neighbourhood vulnerability, measured by Social Vulnerability …

Maternal Health And Sociodemographic Characteristics Influence Infant Growth To 24 Months In The Tunza Mwana Cohort: A Prospective Cohort Study, David Taylor Hendrixson, Mark J Manary, Et Al.

2020-Current year OA Pubs

Upstream pathways influencing child growth are complex. Weight-for-age z-score (WAZ) reflects both ponderal and linear growth and can identify children at high mortality risk. Using data from a prospective cohort of 326 mother-child pairs in Kenya, we evaluated whether associations between maternal exposures and child growth outcomes in early and later childhood. Growth trajectories were examined using locally weighted scatterplot smoothing and piecewise linear mixed-effect models with a knot at age 3 months. Poisson regression models examined associations between maternal characteristics and child underweight (WAZ <  -2) and stunting (LAZ <  -2) before and after 3 months. Mean WAZ increased to a peak at 3 months before declining steadily through 24 months. Lower maternal education (adjusted β [aβ] -0.18; 95% CI: -0.24, -0.13), household crowding (aβ -0.2; 95% CI: -0.28, -0.11), lower wealth quintile (aβ -0.04; 95% CI: -0.06, -0.02) and multiparity (aβ -0.16; 95% CI: -0.23, -0.1) were associated with lower monthly rate of change in WAZ prior to age 3 months. Younger maternal age was associated with an increased monthly rate of change in WAZ (aβ = 0.13; 95% CI: 0.08, 0.18) before 3 months and decreased monthly WAZ (aβ -0.02; 95% CI: -0.03, -0.01) after 3 months. Preterm birth was associated with increased risk of underweight in both periods (aRR 2.77; 95% CI: 1.39-5.50). Maternal mental health, intimate partner violence and adverse childhood experiences were not significantly associated with child growth. Maternal nutritional, socio-economic and household-level factors shape early growth, emphasising the need for cross-sectoral programs to support growth.

Previous brain-wide association studies (BWAS) have linked specific environmental and behavioral variables to brain variability. In this work, we mapped 649 variables to children's brains and compared the resultant BWAS maps with each other and with neurobiological reference patterns. Socioeconomic status (SES) showed the strongest brain-wide associations. The SES associations were strongest in motor and sensory but not cognitive regions, a pattern shared across many BWAS maps, including intelligence quotient (IQ). A single, common BWAS brain pattern existed across variables that was most reflective of a child's socioeconomics. Adjusting for SES weakened brain-IQ associations, eliminating the BWAS motor and sensory …

The Effect Of Hunger On The Likelihood Of Glucose Excursions In Adults With Overweight Or Obesity: Continuous Glucose Monitoring And Ecological Momentary Assessment Observational Study, Byunggul Lim, Phrashiah Githinji, Yue Liao, Jacob Szeszulski, Alexandra L Macmillan Uribe, Rebecca A Seguin-Fowler, Jane Anderson, Chad D Rethorst

Faculty, Staff and Students Publications

Background: Maintaining stable glucose levels is important for metabolic health. Glucose excursions (GEs), which are marked increases in glucose following food intake, have been associated with a higher risk for cardiovascular disease and metabolic dysfunction. Individuals with overweight or obesity who do not have diabetes may still show impaired glucose regulation, as reflected in increased glucose variability. Hunger, as a real-time physiological cue, may be associated with subsequent glucose changes and represents a potential target for just-in-time adaptive interventions.

Objective: This study aimed to investigate the temporal relationship between self-reported hunger and subsequent glucose dynamics, including the likelihood of GE …

Faculty, Staff and Students Publications

Psychological stress can cause diminished immune response to infectious challenges. The extent this holds true during severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the modifying effect of vaccination status is untested. We explored these relationships in a non-random sample standardized to the US adult population. Across 2178 participants in the Aegis study (2021-2022), we identified 507 eligible laboratory-confirmed SARS-CoV-2 infections. We estimated the natural log of nucleocapsid-binding antibody absorbance (N-antibody) at study visits up to 225 days following a positive SARS-CoV-2 test. Linear mixed effects models were fit to estimate the association of baseline perceived stress and, separately, …

Alcohol Consumption And Molecular Subtypes Of Colorectal Cancer: Pooled Observational And Mendelian Randomization Analyses, Christos V Chalitsios, Yin Cao, Et Al.

2020-Current year OA Pubs

BACKGROUND: Alcohol consumption is associated with colorectal cancer (CRC) risk, yet its association with distinct molecular subtypes remains unclear. Clarifying this could reveal insights into alcohol's carcinogenic mechanisms.

OBJECTIVES: We examined the association between alcohol consumption and the risk of CRC subtypes defined by individual tumor markers (and marker combinations), namely microsatellite instability (MSI) status, CpG island methylator phenotype (CIMP) status, BRAF, and KRAS mutations.

METHODS: Pooled observational (n

RESULTS: Among drinkers, each additional 14 g/d of alcohol was associated with a 10% higher CRC risk [odds ratio (OR) = 1.10; 95% confidence interval (CI): 1.07, 1.13], but this association …

An Obligatory Role For Agrp Neurons In Maintaining Body Temperature During Time-Restricted Feeding, Cunjin Su, Jing Cai, Yuanzhong Xu, Benjamin R Arenkiel, Qingchun Tong

The Brown Foundation: Institute of Molecular Medicine

Homeotherms maintain a steady body temperature through thermoregulation, a process critical for survival during fasting, in which the brain has to defend energy-costly body temperature while reducing energy expenditure to conserve energy reserve; however, the neural basis for defending body temperature remains unclear. Here, we demonstrated that AgRP neuron lesion led to lethality during time-restricted feeding on chow but not on HFD, and caused no obvious impact on HFD-induced obesity or obesity-reducing responses to glucagon-like peptide-1 receptor agonism. The lesion disrupted adaptive feeding behaviors during time-restricted feeding and reduced motivational feeding on chow. Notably, the lethality was caused by hypothermia …

Faculty, Staff and Student Publications

Food insecurity and the at-home availability of vegetables and sugar-sweetened beverages both influence dietary intake. However, most research on food insecurity and the at-home availability of vegetables and sugar-sweetened beverages is cross-sectional, which is problematic as both change frequently. Therefore, this study assessed how changes in food insecurity were associated with changes in the at-home availability of vegetables and sugar-sweetened beverages among those in the intervention and control groups of TX Sprouts. Parents who participated in TX Sprouts, a gardening, cooking, and nutrition cluster-randomized trial conducted with primarily Hispanic, low-income 3rd-5th-grade students, completed surveys at baseline and at the nine-month …

A Quantitative Analysis Of Cardiovascular Adaptations To Exercise And Endurance Performance Among Male And Female Collegiate Athletes, Ronnie Wayne Eggleston Jr.

Doctoral Dissertations and Projects

Cardiovascular adaptations to exercise are prominent among endurance athletes. While heart rate is used to determine exercise prescription and to measure overall health, little research has explored the influence of sex-based differences on changes in heart rate and performance outcomes. The purpose of this study is to investigate and compare cardiovascular adaptations to exercise in male and female endurance athletes, with a focus on heart rate and performance times. A quasi-experimental longitudinal design was used with a sample of 19 (nine males, ten females) collegiate triathletes on a university club sports team. Data was collected at the beginning and end …

Maternal Low-Sodium Diet Impairs Hippocampal Neurogenesis And Cognition In Adult Mouse Offspring., Xingrao Ke, Connie C. Grobe, Justin L. Grobe, Wei Yu, John J. Reho, Kaela Varberg, Robert H. Lane, Jeffrey L. Segar

Manuscripts, Articles, Book Chapters and Other Papers

Sodium (Na) homeostasis is critical for organ and cell function. Although low maternal Na intake during gestation is associated with low offspring survival rates and birth weights, the long-term impact on neurocognitive function is not known. Identifying a relationship between perinatal Na dysregulation and adult behavioral and cognitive outcomes may be important given the prevalence of both dysnatremias and neurocognitive impairment in preterm infants. This study aimed to determine the association between maternal low Na intake (LSI) and hippocampal-dependent behaviors in mice. C57BL/6J dams were fed a standard (0.30%) or low (0.04%) Na diet from postnatal day 0 until postnatal …

2020-Current year OA Pubs

BACKGROUND: Preterm birth increases the long-term risk of diabetes and chronic kidney disease (CKD), yet its impact on diabetic kidney disease (DKD) is unclear. We previously showed that male preterm mice with diabetes develop early features of DKD, including reduced podocyte density, decreased renin expression, activation of angiogenesis pathways, and impaired endothelial-podocyte signaling. Here, we examine whether preterm birth similarly accelerates DKD progression in female mice and compare structural and transcriptomic outcomes in the females to the prior male cohort to assess sex-specific differences.

METHODS: Preterm mice were delivered by Caesarean section at 19 days post conception (dpc) and term …

Ready-to-use therapeutic and supplementary foods (RUTF/RUSF) are a primary treatment for childhood malnutrition in Community Management of Acute Malnutrition (CMAM) programs. However, measuring intervention compliance is labor intensive and unreliable. We applied FoodSeq, a fecal genomic dietary assessment biomarker, in malnourished infants (3-15 months) from Matiari, Pakistan. FoodSeq identified a significant increase in the abundance of DNA from chickpea, a primary RUSF ingredient, during RUSF administration and captured region-specific complementary feeding practices, including age-inappropriate feeding practices such as wide-spread tea consumption. Our findings highlight the potential of dietary genomics as an empirical and scalable tool for compliance monitoring and dietary …
