Children’s Nutrition Research Center Staff Publications

Nonsyndromic hearing loss (NSHL) is a genetically diverse, highly heterogeneous condition characterised by deafness, and Gasdermin E (GSDME) variants have been identified as directly inducing autosomal dominant NSHL. While many NSHL cases associated with GSDME involve the skipping of exon 8, there is another, less understood pathogenic insertion variant specifically found in Chinese pedigrees that causes deafness, known as autosomal dominant 5 (DFNA5) hearing loss. In this study, we recruited a large Chinese pedigree, conducted whole‐exome and Sanger sequencing to serve as a comprehensive clinical examination, and extracted genomic DNA samples for co‐segregation analysis of the members. Conservation …

Human fetal membranes (amniochorion) that line the intrauterine cavity consist of two distinct cell layers; single-layer amnion epithelial cells (AEC) and multilayer chorion trophoblast cells (CTC). These layers are connected through a collagen-rich extracellular matrix. Cellular remodeling helps support membrane growth and integrity during gestation and helps to maintain pregnancy. Preterm prelabor rupture of the human amniochorionic (fetal) membrane (pPROM) is antecedent to 40% of all spontaneous preterm birth. Oxidative stress (OS) induced activation of the p38 MAPK due to various maternal risk exposures and the amniochorion cells' senescence are reported pathological features of pPROM. Our transcriptomics analysis implicated dysregulated …

The essential branched-chain amino acids (BCAAs) leucine, isoleucine, and valine play critical roles in protein synthesis and energy metabolism. Despite their widespread use as nutritional supplements, BCAAs' full effects on mammalian physiology remain uncertain due to the complexities of BCAA metabolic regulation. Here a novel mechanism linking intrinsic alterations in BCAA metabolism is identified to cellular senescence and the senescence-associated secretory phenotype (SASP), both of which contribute to organismal aging and inflammation-related diseases. Altered BCAA metabolism driving the SASP is mediated by robust activation of the BCAA transporters Solute Carrier Family 6 Members 14 and 15 as well as downregulation …

Citrulline And Adi-Peg20 Reduce Inflammation In A Juvenile Porcine Model Of Acute Endotoxemia, Caitlin Vonderohe, Barbara Stoll, Inka Didelija, Trung Nguyen, Mahmoud Mohammad, Yava Jones-Hall, Miguel A Cruz, Juan Marini, Douglas Burrin

Faculty, Staff and Students Publications

BACKGROUND: Arginine is a conditionally essential amino acid that is depleted in critically ill or surgical patients. In pediatric and adult patients, sepsis results in an arginine-deficient state, and the depletion of plasma arginine is associated with greater mortality. However, direct supplementation of arginine can result in the excessive production of nitric oxide (NO), which can contribute to the hypotension and macrovascular hypo-reactivity observed in septic shock. Pegylated arginine deiminase (ADI-PEG20, pegargiminase) reduces plasma arginine and generates citrulline that can be transported intracellularly to generate local arginine and NO, without resulting in hypotension, while maintaining microvascular patency. The objective of …

Polygenic Scores And Mendelian Randomization Identify Plasma Proteins Causally Implicated In Alzheimer’S Disease, Davis B Cammann, Yimei Lu, Jerome I Rotter, Alexis C Wood, Jingchun Chen

Faculty, Staff and Students Publications

BACKGROUND: An increasing body of evidence suggests that neuroinflammation is one of the key drivers of late-onset Alzheimer's disease (LOAD) pathology. Due to the increased permeability of the blood-brain barrier (BBB) in older adults, peripheral plasma proteins can infiltrate the central nervous system (CNS) and drive neuroinflammation through interactions with neurons and glial cells. Because these inflammatory factors are heritable, a greater understanding of their genetic relationship with LOAD could identify new biomarkers that contribute to LOAD pathology or offer protection against it.

METHODS: We used a genome-wide association study (GWAS) of 90 different plasma proteins (

RESULTS: We identified …

Children’s Nutrition Research Center Staff Publications

Background: Smith Magenis Syndrome (SMS) is a rare genetic disorder caused by RAI1 haploinsufficiency. Obesity in people with SMS is believed partially due to dysfunction of the proximal melanocortin 4 receptor (MC4R) pathway. We therefore studied effects of treatment with the MC4R agonist setmelanotide on obesity and hunger, as well as metabolic, cardiac and safety, in individuals with SMS.

Methods: People with SMS received once-daily setmelanotide injections, with the dose titrated bi-weekly to a maximum of 3 mg over ∼1 month; and a full-dose treatment duration of 3mo. The primary outcome was percent change in body weight. Secondary outcomes included …

Standardizing Nasogastric Tube Securement: A Quality Improvement Initiative, Shannon Lee Thompkins

Graduate Theses, Dissertations, and Problem Reports (ETD)

Problem: At a large academic medical center located in the northeastern United States, nasogastric tubes (NGT) were traditionally secured with tape. The institutional policy was nonspecific with no written procedure. The inconsistent use of nasal bridle securement devices (NBSD) and predominant use of tape has the potential to lead to a high rate of NGT dislodgement.

Background: NGT complication and dislodgement rates range from 2%-36% (Gimenes et al., 2019). Stabler et al. (2018) report 29%-63% NGT dislodgement rates in critically ill patients. Patients with intracranial hemorrhage dislodge NGTs in 25% of patients (Rahman et al., 2022)

Available Knowledge: Based on …
