Time restricted feeding (TRF) as a form of intermittent fasting (IF) has gained popularity because its ability to reduce body mass (BM) without an emphasis on caloric restriction. However, how this dietary protocol may affect health, fitness, and performance in a relatively healthy cohort remains less clear. The purpose of this article was to systematically review the current literature concerning the effect of TRF on anthropometric, metabolic, and fitness parameters in normal-weight adults and overweight and obese individuals. A systematic search of English literature was conducted through databases including PubMed, CINAHL, and Google Scholar. The search was facilitated by using …

Recognizing Pseudohypobicarbonatemia In Patients With Hypertriglyceridemia - A Case Report, Alisha Vincent, Mohamad Hammad, Brian Clayton

Rowan-Virtua Research Day

Pseudohypobicarbonatemia is a laboratory artifact in which severe hypertriglyceridemia interferes with enzymatic bicarbonate measurements, leading to falsely low levels that can mimic metabolic acidosis. We present a case of a patient with diabetes and hyperlipidemia who was initially found to have profound hypobicarbonatemia and an elevated anion gap, raising concerns for metabolic acidosis. However, arterial blood gas analysis revealed a normal acid-base status, prompting further investigation and identification of severe hypertriglyceridemia (>1100 mg/dL) as the underlying cause. This case highlights the diagnostic challenges posed by hypertriglyceridemia-induced lab errors and underscores the importance of confirming suspected metabolic acidosis with arterial …

Implementation Of The American College Of Cardiology And American Diabetes Association Clinical Practice Guidelines For Statin Therapy In Reducing Cardiovascular Risk Among Patients With Type 2 Diabetes, Edward Eloy Iruegas

Doctor of Nursing Practice

The incidence of type 2 diabetes has significantly increased over the past decade, making it a risk factor for cardiovascular disease (Banach et al., 2022). Individuals with type 2 diabetes are four times more likely to develop atherosclerotic cardiovascular disease, accounting for up to a 75% mortality rate. Despite this, the risk for atherosclerotic cardiovascular disease remains underestimated and undertreated in this population (Banach et al., 2022). The purpose of this project was to enhance adherence to the American College of Cardiology 2019 and the American Diabetes Association 2023 clinical practice guidelines regarding statin therapy for patients with type …

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 …

The Dialysis Foot- The Impact Of Presenting Estimated Glomerular Filtration Rate On Clinical Outcomes In Patients Hospitalized With Diabetic Foot Infections, Arthur Tarricone, Tyler L Coye, Allen Gee, Bijan Najafi, Michael C Siah, Lawrence A Lavery

Center on Aging Staff Publications

To evaluate the association between presenting estimated glomerular filtration rate (eGFR) and clinical outcomes in patients hospitalized with diabetic foot infections. This retrospective cohort study included 344 patients with moderate to severe diabetic foot infections. Patients were categorized into three groups based on presenting estimated eGFR: eGFR ≥60 (eGFR >60 mL/min), eGFR 30-60 (eGFR 30-60 mL/min) and eGFR < 30 (eGFR < 30 mL/min). Outcomes assessed included wound healing, time to heal, re-infection, amputation, mortality and re-hospitalization for infection. Compared with patients with eGFR < 30, patients with eGFR ≥60 had significantly lower rates of retinopathy, peripheral arterial disease and use of beta blockers or calcium channel blockers. Glycated haemoglobin levels were inversely related to eGFR, decreasing as eGFR severity increased. Haemoglobin levels were significantly lower, and inflammatory markers (ESR and CRP) were significantly higher in patients with eGFR < 30. There were no significant differences among eGFR groups in rates of wound healing, time to heal, re-infection or amputation. However, mortality increased with decreasing eGFR (1.9% in eGFR ≥60 vs. 3.2% in eGFR 30-60 vs. 8.1% in eGFR < 30; p = 0.04). Similarly, re-hospitalization for infection at a different site also increased with decreasing eGFR (20.5% in eGFR ≥60 vs. 28.1% in eGFR 30-60 vs. 48.4% in eGFR < 30; p <  0.01). In diabetic foot infections, presenting eGFR severity did not affect rates of wound healing, time to heal, re-infection or amputation. However, decreasing eGFR was associated with increased mortality and re-hospitalization for infection at a different site. In this study, presenting eGFR was not a predictive value for wound healing or time until healing, however was associated with rehospitalization and overall mortality this diabetic foot population.

Manganese-Induced Precocious Puberty Alters Mammary Epithelial Cell Proliferation In Female Rats, Alina M. Hamilton, Vinod K. Srivastava, Jill K. Hiney, William L. Dees, Robert K. Dearth

School of Integrative Biological & Chemical Sciences Faculty Publications

Precocious puberty (PP) is an established breast cancer risk factor. In the normal mammary gland, hormone receptor-positive (HR+) cells rarely proliferate. In breast cancer, proliferating epithelial cells are often HR+. It is not known if PP can modify this population of proliferating HR+ cells. Previously, we established a manganese-induced precocious puberty (MnPP) model to study the effects of PP on mammary gland development in female rats. Here, we characterized the distribution of HR+ proliferating mammary epithelial cells in prepubertal and adult rodents, in association with precocious puberty. Female rats were exposed daily to 10 mg/kg manganese chloride or saline (control) …

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 …

Diabetes Mellitus And Associated Vascular Disease: Pathogenesis, Complications, And Evolving Treatments, Kazi Islam, Rahib Islam, Ivan Nguyen, Hassan Malik, Humza Pirzadah, Barsha Shrestha, Isabella B. Lentz, Sahar Shekoohi, Alan D. Kaye

School of Medicine Faculty Publications

Diabetes mellitus is a metabolic disorder, characterized by elevated blood sugar levels (hyperglycemia) and insulin dysregulation. This disease is associated with morbidity and mortality, including significant potential vascular complications. High levels of hyperglycemia lead to not only elevated levels of reactive oxygen species but also advanced glycation end products, which are detrimental to the vascular endothelium and reduce protective compounds such as nitric oxide and prostacyclin. This damage contributes to the development of both macrovascular and microvascular complications. The present investigation explores the pathophysiological mechanisms of diabetic vascular complications and evaluates current management strategies, including lifestyle modifications, pharmacological treatments, and …

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 …

Integrating Short-Read And Long-Read Single-Cell Rna Sequencing For Comprehensive Transcriptome Profiling In Mouse Retina, Meng Wang, Yumei Li, Jun Wang, Soo Hwan Oh, Yexuan Cao, Rui Chen

Faculty, Staff and Students Publications

The vast majority of protein-coding genes in the human genome produce multiple mRNA isoforms through alternative splicing, significantly enhancing the complexity of the transcriptome and proteome. To establish an efficient method for characterizing transcript isoforms within tissue samples, we conducted a systematic comparison between single-cell long-read and conventional short-read RNA sequencing techniques. The transcriptome of approximately 30,000 mouse retina cells was profiled using 1.54 billion Illumina short reads and 1.40 billion Oxford Nanopore Technologies long reads. Consequently, we identify 44,325 transcript isoforms, with a notable 38% previously uncharacterized and 17% expressed exclusively in distinct cellular subclasses. We observe that long-read …

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 …

Heterozygous Hereditary Vitamin D-Dependent Rickets Type 2a (Vddr2a) In A Patient Presenting With Pseudoarthrosis, Risa Goldberg, Gunjan Umarji, Serge Jabbour

Division of Endocrinology, Diabetes and Metabolic Diseases Faculty Papers

This case report is centered on an atypical presentation of Hereditary Vitamin D-dependent Rickets 2A (VDDR2A), a rare disorder caused by defects in the gene encoding the vitamin D receptor (VDR). While this disorder is primarily autosomal recessive in inheritance, this case demonstrates that a single heterozygous variant in the VDR gene could be linked to both phenotypic and laboratory manifestations of this condition. To understand the pathogenesis of this condition, one must know the typical roles of vitamin D, calcium, and parathyroid hormone (PTH) in maintaining homeostasis in the body. This case report focuses on the underlying pathogenesis of …

Vestibular Neurons Link Motion Sickness, Behavioural Thermoregulation And Metabolic Balance In Mice, Longlong Tu, Xing Fang, Yongjie Yang, Meng Yu, Hailan Liu, Hesong Liu, Na Yin, Jonathan C Bean, Kristine M Conde, Mengjie Wang, Yongxiang Li, Olivia Z Ginnard, Qingzhuo Liu, Yuhan Shi, Junying Han, Yi Zhu, Makoto Fukuda, Qingchun Tong, Benjamin Arenkiel, Mingshan Xue, Yang He, Chunmei Wang, Yong Xu

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 …

Lim

Research outputs 2022 to 2026

Deceased donor kidney allocation relies on HLA compatibility at the antigen level, as optimal matching reduces the risk of acute rejection. Whether HLA allele-level mismatches improve, the prediction of acute rejection after transplantation remains unclear. Using data from the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA) from 2017 to 2020, HLA antigenic and allelic mismatches between recipients and deceased donors were calculated with imputation of two-field allelic equivalents undertaken where required. The discordance between antigen and allele mismatches was calculated, and oblique random survival forest models were used to predict acute rejection. Predictive performance of antigen (HLA-A, -B, …

Faculty, Staff and Students Publications

Patients with undiagnosed and/or rare disorders frequently manifest dysmorphic and neurological features. There is a lack of information on the effectiveness of telehealth in the evaluation of these disorders. We thus compared an unassisted virtual physical examination (PE) with an in-person PE in undiagnosed individuals and also assessed participant telehealth satisfaction. Twenty-six individuals enrolled in the Undiagnosed Diseases Network study underwent an in-home synchronous virtual PE, and a subsequent in-person PE, by the same clinician. The participants completed surveys on telehealth usability and provider empathy. On PE, general appearance and craniofacial features showed near perfect agreement (κ = 0.81-1.00) between …

Most Elderly Patients With Subclinical Hypothyroidism Do Not Need To Be Treated, Risheng Xu, Nicola Abate, Nalini Ram, Kristina Little

Faculty, Staff and Students Publications

Whether subclinical hypothyroidism should be treated in elderly patients (≥ 65 years) is controversial. The authors argue for a personalized, wait-and-see approach rather than universal treatment, pointing out that randomized clinical trials have not shown that levothyroxine treatment makes any difference in terms of hard clinical end points, quality of life, or hypothyroid symptom relief in elderly patients with this condition.

Previous studies suggested that fecal short-chain fatty acids (SCFAs) and branched short-chain fatty acids (BCFAs) are associated with glucose regulation. However, the potential relationship between circulating SCFAs and BCFAs with incident diabetes risk in both men and women remains unidentified in prospective cohort studies. In this study, we examined a panel of nine serum SCFAs and BCFAs in 3414 subjects with incident diabetes, and matched normoglycemic controls from the China Cardiometabolic Disease and Cancer Cohort study. In fully adjusted conditional logistic regression models, total SCFAs, total BCFAs, and isovaleric acid were significantly associated with incident type 2 diabetes mellitus (T2DM) …
