School of Public Health Faculty Publications

Background: Dietary management is key to preventing and controlling type 2 diabetes mellitus (T2DM). However, few studies have examined differences in Healthy Eating Index (HEI-2020) scores and components among individuals with and without diagnosed T2DM. This study aimed to assess gender differences in HEI-2020 scores and its 13 components by T2DM status. Methods: Using National Health and Nutrition Examination Survey (NHANES) data from 2011 to 2018, this cross-sectional study analyzed 19,464 adults. Diagnosed T2DM was identified via self-report or diabetes medication use. Diet quality was assessed using the HEI-2020, scored from 0 to 100, with a higher HEI score indicates …

Examining The Benefits Of A Standardized Protocol For Hyperglycemia Screening In Adult Oncology Patients: A Pilot Study, Alexa Dashko

Pacific Journal of Health

Many individuals receiving cancer directed therapy are at risk of developing hyperglycemia and new, or worsening of, diabetes due to location of their cancer, treatment regimen, and/or prolonged use of steroids. Research shows that uncontrolled hyperglycemia can have detrimental effects on individuals’ response to cancer therapy, treatment associated toxicities, quality of life and overall mortality. Despite extensive research identifying the need for routine monitoring and management of hyperglycemia in oncology patients, medical societies have yet to establish formal screening guidelines for practitioners. The aim of this pilot study was to examine the outcomes of establishing a protocol for screening and …

Children’s Nutrition Research Center Staff Publications

During weaning, the transition to solid food diversifies the gut microbiome, triggering a programmed immune response critical for long-lasting mucosal immunity. Previous work showed that the gut microbiome mediates epigenetic development in intestinal stem cells (ISCs) during suckling, but what happens during weaning is unclear. Here, genome-wide profiling revealed that weaning-driven microbiome changes shape the DNA methylome and transcriptome of murine ISCs in an IFNγ-dependent manner. Specifically, we observe demethylation of enhancer elements essential for MHC class II genes, which results in a transcriptional memory that persists through differentiation into adulthood. IFNγ blockade, or low-dose penicillin to target Gram-positive bacteria, …

Endometriosis is a chronic gynecological disorder marked by the growth of endometrial-like tissue outside the uterus, often leading to pelvic pain, inflammation, and infertility. Despite its global prevalence, diagnosis remains delayed, and effective non-surgical treatments are lacking. While recent transcriptomic studies have identified mRNA transcript changes in ectopic lesions, the contribution of alternative pre-mRNA splicing, a key posttranscriptional regulatory layer, remains largely unknown. In this study, we performed a comprehensive analysis of alternative splicing (AS) events in endometriotic lesions using transcriptomic data. We uncovered distinct alterations in alternative splicing events are associated with endometriosis, highlighting a previously underappreciated layer of …

Inverse Associations Of Serum Total Omega-6 Polyunsaturated Fatty Acids And Linoleic Acid With Biomarkers Of Inflammation: A Cross-Sectional Analysis, Kevin C Maki, Xiwei Chen, Meredith L Wilcox, Carol F Kirkpatrick, Liana L Guarneiri, Orsolya M Palacios, Erika T Beidelman, Anna Lm Macagno, David B Allison

Children’s Nutrition Research Center Staff Publications

Background: Observational evidence supports associations between higher consumption of omega-6 (n-6) polyunsaturated fatty acids (PUFAs) with reduced risks for cardiometabolic diseases. However, some have hypothesized that higher n-6 PUFA intake may be proinflammatory.

Objectives: The purpose of this cross-sectional analysis using baseline data from the Aegis cohort was to examine associations of serum total n-6 PUFA and linoleic acid concentrations with biomarkers of inflammation.

Methods: Serum concentrations of high-sensitivity C-reactive protein (hs-CRP), glycoprotein acetyls, serum amyloid A (SAA), soluble intercellular adhesion molecule-1 (sICAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) were assessed as biomarkers of inflammation. Univariate Pearson correlation coefficients …

We experienced a 45-year-old male with ADPKD who developed spontaneous retroperitoneal hemorrhages with hypertension in the right subcapsular renal space without trauma. After his condition worsened with conservative management, he was treated by renal transarterial embolization (TAE). Over the next eight years, he experienced bilateral bleeding at three different sites and underwent repeated endovascular treatment with renal TAE to stop the bleeding. After the fourth occurrence, the patient underwent hemodialysis. Although renal cysts and urinary tract bleeding occur frequently in ADPKD, retroperitoneal hemorrhage is rare; however, TAE is both effective and a good way to preserve renal function.

The arcuate nucleus of the hypothalamus plays a central role in sensing and integrating nutritional, hormonal, and neural signals that regulate feeding, energy homeostasis, growth, and reproduction, all of which show pronounced sex differences. However, the cellular mechanisms underlying these responses remain poorly understood. We performed snRNA-seq of the mediobasal hypothalamus, focusing on the arcuate nucleus, in female and male mice under different nutritional states. Analysis of 42 cell types revealed that Agrp neurons were most sensitive to nutritional changes, dopaminergic neurons showed strong sex-specific differences, and KNDy neurons were highly responsive to both sex and nutrition. Pomc neurons displayed …

Children’s Nutrition Research Center Staff Publications

Background: Digital health interventions (DHIs) can extend the reach of disease prevention interventions; however, few are evidence-based, theoretically grounded, or developed for high-risk youth and families. Co-design approaches engage end users in the design and development of the DHI, which can lead to increased accessibility and engagement.

Objective: This study aimed to describe the adaptation of an evidence-based diabetes prevention program for remote, digital delivery.

Methods: The adaptation of the in-person intervention was guided by a modified Inclusive Digital Health Intervention Design to Promote Health Equity framework and conducted in collaboration with Hispanic adolescents (n=23) with obesity (BMI ≥95th percentile) …

A Framework For Assessing The Trustworthiness Of Scientific Research Findings, Brian A Nosek, David B Allison, Kathleen Hall Jamieson, Marcia Mcnutt, A Beau Nielsen, Susan M Wolf

Children’s Nutrition Research Center Staff Publications

Vigorous debate has erupted over the trustworthiness of scientific research findings in a number of domains. The question "what makes research findings trustworthy?" elicits different answers depending on whether the emphasis is on research integrity and ethics, research methods, transparency, inclusion, assessment and peer review, or scholarly communication. Each provides partial insight. We offer a systems approach that focuses on whether the research is accountable, evaluable, well-formulated, has been evaluated, controls for bias, reduces error, and whether the claims are warranted by the evidence. We tie each of these components to measurable indicators of trustworthiness for evaluating the research itself, …

Impaired Arginine, Citrulline And Glutamine Metabolism In Type 2 Diabetes: Insights From A Stable Isotope Study, Mustafa Tosur, Raven A Wierzchowska-Mcnew, Nicolaas E P Deutz, Mariëlle P K J Engelen

Children’s Nutrition Research Center Staff Publications

Context: Arginine (Arg) is an important amino acid in T2D as a potent insulin secretagogue and precursor for nitric oxide (NO). Citrulline (Cit), the substrate for de novo Arg synthesis, is mostly produced from glutamine (Gln).

Objective: We aimed to investigate their metabolism in T2D using novel stable isotope tracer approach.

Methods: We studied 42 individuals (21 with T2D, 21 controls). After overnight fasting, blood samples were collected following pulse administration of stable amino acid tracers. Plasma concentrations and isotopic enrichments were measured by LC-MS/MS, and compartmental analyses were performed to calculate their whole-body production (WBP) rates and kinetics.

An Autopsy Case Of Extensive Aortic Thrombosis With Acute Kidney Injury As The Sole Clinical Manifestation, Risa Suenaga, Makoto Fukuda, Atsuhiko Suenaga, Yuki Ikeda, Maki Yoshihara, Megumi Nishiyama, Seiichi Kato, Motoaki Miyazono

Children’s Nutrition Research Center Staff Publications

Aortic thrombosis is a rare but life-threatening condition. It typically presents with abdominal or lower-limb ischemia. Although acute kidney injury (AKI) can accompany aortic thrombosis, AKI as the sole clinical manifestation has not been previously reported. A 69-year-old man with extensive atherosclerotic disease and chronic kidney disease presented with severe oliguria. Initial evaluation, including non-contrast computed tomography (CT), did not reveal any aortic abnormalities. Renal Doppler ultrasonography findings and markedly elevated D-dimer levels prompted contrast-enhanced CT, which demonstrated extensive thrombus formation extending from the descending thoracic aorta to the bilateral iliac arteries, with complete occlusion of both renal arteries and …

Pair-Feeding Study Designs Can Create Biases And Inflate Type I Error Rates: A Simulation Study, Wasiuddin Najam, Daniel E Kpormegbey, Deependra K Thapa, Bret Rust, Lilian Golzarri-Arroyo, Lance H Baumgard, Louis Wai-Tong Fan, Joseph G Ibrahim, Edith J Mayorga, David B Allison

Children’s Nutrition Research Center Staff Publications

Objective: Pair-feeding is a study design element where one group's food intake is provided to another group to assess whether a treatment effect is independent of food intake. Investigators often assume equivalent food intake across experimental conditions and exclude it from the statistical analysis. However, the impact of this practice on type I error (T1Er) rates has not been quantified.

Methods: We conducted a Monte Carlo simulation in which animals were assigned baseline weights and food intakes, then randomized to non-pair-fed or pair-fed groups. Daily food intake for both groups was initially drawn from the baseline food intake distribution. For …

Life-Extending Interventions Do Not Necessarily Result In Compression Of Morbidity: A Case Example Offering A Robust Statistical Approach, Deependra K Thapa, Wasiuddin Najam, Erik S Parker, Xi Rita Wang, Daniel L Smith, Ufuk Beyaztas, James F Nelson, Steven N Austad, Gary A Churchill, David B Allison

Children’s Nutrition Research Center Staff Publications

Despite extensive research on life-extending interventions, rigorous statistical techniques to determine their impact on compression of morbidity (CoM) are rarely used. We present a case example of an analytical method for examining the effect of life-extending dietary interventions on CoM by comparing the rates of decline in vitality and survival toward the end of life. Using data from previous experimental studies in mice, we calculated the average rate of vitality decline by fitting exponential decay models to individual vitality trajectories and compared this rate with the rate of survival decline estimated from Cox proportional hazards model. The results showed that, …

Type 2 diabetes (T2D) is a prevalent disease arising from complex molecular mechanisms. Here we leverage T2D genetic associations to identify causal molecular mechanisms in an ancestry-aware and tissue-aware manner. Using two-sample Mendelian randomization corroborated by colocalization across four global ancestries, we analyse 20,307 gene and 1,630 protein expression levels using blood-derived cis-quantitative trait loci (QTLs). We detect causal effects of genetically predicted levels of 335 genes and 46 proteins on T2D risk, with 16.4% and 50% replication in independent cohorts, respectively. Using gene expression cis-QTLs derived from seven T2D-relevant tissues, we identify causal links between the expression of 676 …

Enteral And Intravenous Supplementation Of Arginine And Citrulline Fail To Prevent Necrotizing Enterocolitis In Preterm Neonatal Pigs, Caitlin Vonderohe, Julia Garcia Mancebo, Valeria Melendez Hebib, Barbara Stoll, Inka Didelija, Sarah Elefson, Mahmoud Mohammad, Brooklynn Earls, Greg Guthrie, Doug Burrin

Children’s Nutrition Research Center Staff Publications

Background: Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency in preterm infants with a morality rate that approaches 50%. Arginine has been widely studied in the field of clinical nutrition as a supplement for patients experiencing critical illness because it can be metabolized into nitric oxide, an important agent for supporting immunity and microcirculation. Citrulline has received less attention but can be metabolized into arginine and has a much longer plasma half-life than arginine. We used the highly translational preterm pig model to determine the effect of intravenous and enteral supplementation of arginine and citrulline on NEC incidence in …

Children’s Nutrition Research Center Staff Publications

Background: Cardiorespiratory fitness is an integrative measure of cardiometabolic health and predictor of survival, yet little is known about its molecular underpinnings. Small molecule metabolites and lipids are increasingly recognized as exercise-stimulated signaling molecules and candidate molecular transducers of cardiorespiratory fitness.

Methods: We performed nontargeted liquid chromatography mass spectrometry-based plasma metabolomics in 654 participants (mean age, 35 years; 55% women) from the HERITAGE Family Study (Health, Risk Factors, Exercise Training, and Genetics) who had cardiorespiratory fitness (maximal oxygen uptake [VO2max]) measured by cardiopulmonary exercise testing and underwent 20 weeks of supervised endurance training. Metabolite-VO2max relationships were assessed using linear regression …

Association Between Ultraprocessed Food Consumption And Cardiovascular Disease Risk: Mesa (Multiethnic Study Of Atherosclerosis), Amier Haidar, Rishi Rikhi, Karol E Watson, Alexis C Wood, Michael D Shapiro

Children’s Nutrition Research Center Staff Publications

Background: Ultraprocessed foods (UPFs) have been linked to adverse cardiometabolic outcomes and increased atherosclerotic cardiovascular disease (CVD) (ASCVD) risk. However, prior research has largely focused on homogenous populations, lacking racial and ethnic diversity.

Objectives: The objectives are to examine the longitudinal relationship between UPF consumption and ASCVD risk and to investigate whether these associations differ by race/ethnicity, sex, or socioeconomic status.

Methods: The MESA (Multiethnic Study of Atherosclerosis) is a prospective cohort study of 6,814 U.S. adults aged 45 to 84 years, without clinically apparent CVD. UPF consumption was classified according to the Nova classification system. Multivariable cox proportional hazards …

The Impact Of Gastric Sleeve And Roux-En-Y Gastric Bypass On Chief Cell Function And Protein Digestion In Obese Patients, Garikoitz Mikel Gainza

Honors Undergraduate Theses

Obesity has become one of the largest global health concerns of the 21^st century, correlating with numerous associated diseases. To help address the growing prevalence and burden of obesity, sleeve gastrectomy and Roux-en-Y gastric bypass have become two commonly performed surgical procedures done to promote weight loss by altering the anatomical structure of the stomach and surrounding organs of the gastrointestinal system. Although the benefits of improved metabolism linked to these surgical procedures are well studied, their impact on the physiology of gastric cells, and more specifically chief cells as they relate to protein digestion post-surgery, is yet to …

Children’s Nutrition Research Center Staff Publications

Nutrition epidemiological models involve many analytic decisions, such as defining exposures, selecting which covariates to include, or configuring variables in different ways. We explored the impact of analytical decisions on conclusions in nutrition epidemiology using self-reported beef intake and incident coronary heart disease as a case study. We used REasons for Geographic and Racial Differences in Stroke (REGARDS) data, and selected covariates and their configurations from published literature to recapitulate common models used to assess associations between meat intake and health outcomes. Three model sets were designed: sets one and two used continuous and quintile-defined beef intakes, respectively, each with …

Children’s Nutrition Research Center Staff Publications

Background: A deficiency of immunosuppressive regulatory T cells, as seen in scurfy (SF) mice or in IPEX syndrome in humans, can lead to multiorgan inflammation. Oral administration of the probiotic Limosilactobacillus reuteri Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH (DSM) 17938 prolongs survival and reduces Th1- and Th2-associated inflammation in SF mice. It remains unclear how DSM 17938-educated SF-CD4+ T cells modulate T-cell-liver communication.

Methods: To characterize CD4+ T cells from SF mice orally administered DSM 17938 (Prob-SF-CD4+ T cells) and to compare them with CD4+ T cells from SF mice (SF-CD4+ T cells), cells isolated from SF spleens were …

Sleep-Disordered Breathing Subtypes And Future Diet Quality In The Multi-Ethnic Study Of Atherosclerosis, Kaitlin S Potts, Cecilia Castro-Diehl, Tianyi Huang, Alexis C Wood, Jerome I Rotter, Stephen S Rich, Tamar Sofer, Susan Redline, Heming Wang

Children’s Nutrition Research Center Staff Publications

Objectives: Sleep-disordered breathing (SDB) and diet quality impact cardiometabolic disease, but few studies have examined if SDB influences diet quality. This study estimated the association between SDB subtypes (with and without sleepiness) and future diet quality in the Multi-Ethnic Study of Atherosclerosis.

Methods: Probable SDB was characterized by self-reported physician-diagnosed sleep apnea (PDSA) or habitual snoring and subtyped by presence or absence of sleepiness. A food frequency questionnaire measured diet 1.6 years before, and 7.8 years after SDB assessment. Diet quality was measured with the Alternate Healthy Eating Index-2010 (AHEI). Mean differences in AHEI at follow-up by SDB subtypes were …

Concerns Regarding The Standard Deviation Of Individual Responses For Assessing Treatment Response Heterogeneity, Aaron R Caldwell, David B Allison, Andrew W Brown, Gary L Gadbury, Thirupathi Reddy Mokalla, R Drew Sayer, Andrew D Vigotsky

Children’s Nutrition Research Center Staff Publications

The estimation of treatment response heterogeneity (TRH) is increasingly important as medicine moves toward personalized approaches. While various statistical methods have been proposed to quantify TRH in parallel-group trials, the standard deviation of individual responses (SDIR) has gained prominence within physiological research. This method is intended to quantify individual response variation by comparing standard deviations of change scores between intervention and control groups. We acknowledge that SDIR represents an improvement over many other flawed approaches that often involve responder counting. However, SDIR has critical limitations: 1) it cannot overcome the fundamental problem of causal inference because the correlation between potential …
