The Small Gtpase Rap1 In Pomc Neurons Regulates Leptin Actions And Glucose Metabolism, Kentaro Kaneko, Weisheng Lu, Yong Xu, Alexei Morozov, Makoto Fukuda

Faculty, Staff and Students Publications

The hypothalamic leptin-proopiomelanocortin (POMC) pathway is critical for regulating metabolism. POMC neurons in the arcuate nucleus respond to leptin and play a pivotal role in mediating energy and glucose balance. However, during diet-induced obesity (DIO), these neurons often develop resistance to exogenous leptin. Recently, the small GTPase Rap1 has been implicated as an inhibitor of neuronal leptin signaling; however, its specific role within POMC neurons remains unexplored. We generated tamoxifen-inducible, POMC neuron-specific Rap1 knockout mice to selectively delete both Rap1a and Rap1b isoforms in POMC neurons. By analyzing these mice through metabolic phenotyping, immunohistochemistry, and biochemical assays, we show that …

Starting at middle age, adults often suffer from visceral adiposity and associated adverse metabolic disorders. Lineage tracing in mice revealed that adipose progenitor cells (APCs) in visceral fat undergo extensive adipogenesis during middle age. Thus, despite the low turnover rate of adipocytes in young adults, adipogenesis is unlocked during middle age. Transplantations quantitatively showed that APCs in middle-aged mice exhibited high adipogenic capacity cell-autonomously. Single-cell RNA sequencing identified a distinct APC population, the committed preadipocyte, age-enriched (CP-A), emerging at this age. CP-As demonstrated elevated proliferation and adipogenesis activity. Pharmacological and genetic manipulations indicated that leukemia inhibitory factor receptor signaling was …

The Impact Of Sensory Sensitivity On Nutritional Outcomes In Children With Neurodevelopmental Disorders, Rachel M. Qualley

Theses and Dissertations

Background/Objective: Children with neurodevelopmental disorders (NDDs) are at increased risk of malnutrition due to restrictive dietary patterns and behavioral difficulties at mealtimes. Research suggests that heightened sensory sensitivity, a characteristic accompanying several of these disorders, may be a contributing factor. However, the effects of sensory sensitivity on nutritional outcomes across distinct NDDs have not been fully explored. This review aims to examine the relationship between sensory sensitivity and nutritional status, food preferences, and eating behaviors in children with NDDs, specifically investigating how atypical sensory processing might influence dietary intake.

Methods: A literature search was conducted using Google Scholar, PubMed, …

The Impact Of An Iron-Rich Diet On Fatigue In Menstruating Women With Non-Anemic Iron Deficiency, Meagan Seraydar, Lauren Latimer, Sam Miragliatto

Department of Nutrition Student Projects

Fatigue without diagnosed anemia is prevalent in menstruating women, with iron deficiency being a potential contributor. While iron supplementation is a standard intervention, dietary sources of iron may offer a sustainable alternative. This study aims to assess the impact of an iron-rich diet on fatigue levels in menstruating women. A 12-week randomized controlled trial (RCT) will be conducted, assigning participants to either an iron-rich diet group or a control group following their usual diet without specific iron recommendations. Fatigue will be measured using the Fatigue Severity Scale (FSS) at baseline, six weeks, and twelve weeks, alongside iron status biomarkers, including …

Exploring The Acute Effects Of Sedentary Behaviors On Cardiometabolic Risk In Hispanic Adolescents With Obesity: A Randomized Crossover Study, Erica G Soltero, Osamah Salim, Yiming Mirabile, Salma M Musaad

Children’s Nutrition Research Center Staff Publications

Background/Objectives: Time spent in sedentary pursuits is associated with adverse metabolic profiles. Adolescents spend 65-75% of their day in sedentary pursuits; however, evidence among youth is less conclusive. This study examined the effects of an acute 4 h bout of sedentary behaviors on cardiometabolic outcomes and energy expenditure in Hispanic adolescents (12-16 years old) with obesity (BMI% ≥ 95th).

Methods: This study used a randomized cross-over design to engage participants (N = 12) in two sedentary conditions, an active condition where youth were engaged in two hours of 'active' sitting activities (e.g., reading and puzzles) and two hours …

The Impact Of Energy Intake And Macronutrient Distribution On Recovery Rates In Young Women With Functional Hypothalamic Amenorrhea, Hadley Day, Rebecca Lyons, Taylor Vas

Department of Nutrition Student Projects

Functional hypothalamic amenorrhea (FHA) is characterized by irregular or absent menstrual cycles due to disturbances in the hypothalamic-pituitary-ovarian (HPO) axis. Young women ages 18-25 are particularly vulnerable to FHA, which can have long-term consequences on bone health, fertility, and overall well-being. While meeting energy needs is essential for recovery, the question arises of whether different macronutrient distributions within an energy-sufficient diet influence the recovery rate. This study aims to evaluate the impact of varying macronutrient compositions on the recovery of young women with FHA. The study will be conducted using a randomized controlled trial design to examine whether diets with …

Maternal Carbohydrate-Controlled Diets And The Impact On Neonatal Hypoglycemia Rates, Jenna L. Klopping

Student Scholarly Projects

Practice Problem: Neonatal hypoglycemia has a profound impact on the diabetic maternal infant dyad and their families. The practice problem negatively affects the quality of care offered by healthcare providers, while also imposing a financial burden on the healthcare system that extends well beyond the perinatal period.

PICOT: In term infants born to diabetic mothers (P), does a regular carbohydrate-controlled diet given at least 8 hours prior to birth (I) in comparison to a clear liquid carbohydrate-controlled diet (C) reduce the incidence of neonatal hypoglycemia at two hours of life(O) across an 8-week period(T)?

Evidence: A medical nutrition diet, such …

Children’s Nutrition Research Center Staff Publications

Background: Maternal periodontal disease is associated with preterm and low-birthweight deliveries, but randomized trials of likely efficacious treatments (e.g., dental scaling and root planing) during pregnancy have not reduced these adverse outcomes. As an alternative, we hypothesized that periconception initiation of xylitol chewing gum would reduce the occurrence of preterm or low-birthweight deliveries among a historical high-prevalence population in Malawi.

Methods: We conducted an open-label, parallel-enrollment, matched-pair, cluster-randomized, controlled clinical trial across eight health centers (sites) in and around Lilongwe, Malawi. Sites were paired by anticipated delivery volume and randomized to prenatal and oral health education alone (active control) or …

Motion sickness is associated with thermoregulation and metabolic control, but the underlying neural circuitry remains largely unknown. Here we show that neurons in the medial vestibular nuclei parvocellular part (MVePC) mediate the hypothermic responses induced by motion. Reactivation of motion-sensitive MVePC neurons recapitulates motion sickness in mice. We show that motion-activated neurons in the MVePC are glutamatergic (MVePCGlu), and that optogenetic stimulation of MVePCGlu neurons mimics motion-induced hypothermia by signalling to the lateral parabrachial nucleus (LPBN). Acute inhibition of MVePC-LPBN circuitry abrogates motion-induced hypothermia. Finally, we show that chronic inhibition of MVePCGlu neurons prevents diet-induced obesity and improves glucose homeostasis …

Specifically, this document: 1) addresses the current lack of measurable high-quality metrics in cardio-oncology and their implications; 2) highlights needs and topic-specific barriers; 3) illustrates the process and application of a measurable quality metric; and 4) provides a framework to demonstrate measurable value for the growing population of patients with cancer and cardiovascular diseases.

Demographic Clinical Trial Diversity Assessment Methods: Use Of Real-World Data, Hua Chen, Nnadozie Emechebe, Sudeep Karve, Leon Raskin, Jailene Leal, Ning Cheng, Wendy Sebby, Kim Ribeiro, Samuel Crawford

Children’s Nutrition Research Center Staff Publications

Diversity in clinical trials is defined by the inclusion of clinical trial participants from various demographic groups that are representative of the broader population impacted by a disease state. Diversity in clinical trials is critical in identifying potential differences in safety and efficacy of treatments across races, ethnicities, ages, sexes, or other variables. In the United States, clinical trial diversity is often benchmarked against US Census data, which may limit the representativeness of patient demographics in clinical trials. Disease-specific, demographic estimates from real-world data (RWD) can facilitate benchmarking of clinical trials, support trial enrollment and the development of trial diversity …
