This retrospective, single-center chart review studied the use of an in-line, immobilized lipase cartridge (ILC) in children with short bowel syndrome (SBS) at Children's Mercy Hospital. For parenteral nutrition (PN)-dependent patients, the primary endpoint was enteral feeding progression, evaluated by comparing monthly change from baseline in PN and enteral nutrition (EN) after the start of ILC use. For patients with enteral autonomy, changes from baseline in growth measure z-scores were evaluated. In 9 PN-dependent patients (with Type II or III SBS), mean PN use decreased 10.6 kcal/kg/day (15.5%) and mean EN use increased by 6.0 kcal/kg/day (39.9%) after 3.8 to …

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 21st 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 …

Egg White Hydrolysate In Hypertension: A Mechanistic Investigation Of Gut Microbiota Dependent And Independent Pathways, Emerson David Nolasco

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Cardiovascular diseases are one of the leading causes of mortality worldwide in which hypertension is a risk factor. Present pharmacological interventions require long-term adherence to the therapy and are often associated with undesirable side effects. Moreover, treatments have overlooked the role of the microbiome in the development of hypertension. Egg white hydrolysate (EWH) has exhibited antihypertensive properties with potential to be used as a natural alternative for the prevention and management of hypertension. However, EWH peptide’s effect on the gut microbiome remains yet to be elucidated. Studies have described that a portion of the ingested protein can remain undigested as …

Natural Killer Cell Effector Function Is Critical For Host Defense Against Alcohol-Associated Bacterial Pneumonia, Daniel Villageliu, Kelly C. Cunningham, Deandra R. Smith, Daren L. Knoell, Mason Mandolfo, Todd A. Wyatt, Derrick R. Samuelson

Food for Health: Publications

Alcohol use is an independent risk factor for the development of bacterial pneumonia due, in part, to impaired mucus-facilitated clearance, macrophage phagocytosis, and recruitment of neutrophils. Alcohol consumption is also known to reduce peripheral natural killer (NK) cell numbers and compromise NK cell cytolytic activity, especially NK cells with a mature phenotype. However, the role of innate lymphocytes, such as NK cells during host defense against alcohol-associated bacterial pneumonia is essentially unknown. We have previously shown that indole supplementation mitigates increases in pulmonary bacterial burden and improves pulmonary NK cell recruitment in alcohol-fed mice, which were dependent on aryl hydrocarbon …

Suspected Thiamine Deficiency Secondary To Chronic Gastrointestinal Illness: A Case Report, Abigail L. Meckley, Natalie Lagattuta, Elise Gonzalez, Chamonix Kinimaka, Jessica El-Bahri

HCA Healthcare Journal of Medicine

Introduction

Thiamine deficiency, also known as beriberi, is a nutritional disorder caused by a lack of thiamine (vitamin B1) in the diet. It can occur in 2 forms: dry beriberi, which affects the nervous system, and wet beriberi, which affects the cardiovascular system. Gastrointestinal beriberi is a subtype that affects the digestive system and can lead to multisystem involvement. In the United States (US), thiamine deficiency often arises from chronic malnutrition secondary to alcoholism, known as Wernicke-Korsakoff Syndrome.

Mechanistic investigation of host-microbe interactions in the human gut are hindered by difficulty of co-culturing microbes with intestinal epithelial cells. On one hand the gut bacteria are a mix of facultative, aerotolerant or obligate anaerobes, while the intestinal epithelium requires oxygen for growth and function. Thus, a coculture system that can recreate these contrasting oxygen requirements is critical step towards our understanding microbial-host interactions in the human gut. Here, we demonstrate Intestinal Organoid Physoxic Coculture (IOPC) system, a simple and cost-effective method for coculturing anaerobic intestinal bacteria with human intestinal organoids (HIOs). Using commensal anaerobes with varying degrees of oxygen …

Previously, we described the RNA recombinants accumulating in tissues infected with the bromoviruses BMV (Brome mosaic virus) and CCMV (Cowpea chlorotic mottle virus). In this work, we characterize the recombinants encapsidated inside the purified virion particles of BMV and CCMV. By using a tool called the Viral Recombination Mapper (ViReMa) that detects recombination junctions, we analyzed a high number of high-throughput sequencing (HTS) short RNA sequence reads. Over 28% of BMV or CCMV RNA reads did not perfectly map to the viral genomes. ViReMa identified 1.40% and 1.83% of these unmapped reads as the RNA recombinants, respectively, in BMV and …

Emerging evidence indicates that antibiotic-induced dysbiosis can play an etiological role in the pathogenesis of neuropsychiatric disorders. However, most of this evidence comes from rodent models. The objective of this study was to evaluate if antibiotic-induced gut dysbiosis can elicit changes in gut metabolites and behavior indicative of gut-brain axis disruption in common marmosets (Callithrix jacchus) – a nonhuman primate model often used to study sociability and stress. We were able to successfully induce dysbiosis in marmosets using a custom antibiotic cocktail (vancomycin, enrofloxacin and neomycin) administered orally for 28 days. This gut dysbiosis altered gut metabolite profiles, …

Faculty, Staff and Students Publications

Copper is an essential trace element that is required for the activity of many enzymes and cellular processes, including energy homeostasis and neurotransmitter biosynthesis; however, excess copper accumulation results in significant cellular toxicity. The liver is the major organ for maintaining copper homeostasis. Inactivating mutations of the copper-transporting P-type ATPase, ATP7B, result in Wilson’s disease, an autosomal recessive disorder that requires life-long medicinal therapy or liver transplantation. Current treatment protocols are limited to either sequestration of copper via chelation or reduction of copper absorption in the gut (zinc therapy). The goal of these strategies is to reduce free copper, redox …

In fungi, conserved homeobox-domain proteins are transcriptional regulators governing development. In Aspergillus species, several homeobox-domain transcription factor genes have been identified, among them, hbxA/hbx1. For instance, in the opportunistic human pathogen Aspergillus fumigatus, hbxA is involved in conidial production and germination, as well as virulence and secondary metabolism, including production of fumigaclavines, fumiquinazolines, and chaetominine. In the agriculturally important fungus Aspergillus flavus, disruption of hbx1 results in fluffy aconidial colonies unable to produce sclerotia. hbx1 also regulates production of aflatoxins, cyclopiazonic acid and aflatrem. Furthermore, transcriptome studies revealed that hbx1 has a broad effect on …

We read with interest the study by Kayisoglu et al1 comparing the gene expression between embryo-derived and adult-derived intestinal organoids. Some innate immune system genes were differentially expressed between the two organoid types, suggesting a potential role of exposure to the environment, including gut microbiota, in shaping the intestinal gene expression. In extremely preterm infants (<32 weeks gestation), microbial–host interaction at the epithelial surface has been associated with various morbidities including late onset sepsis and necrotising enterocolitis.2 Thus, preterm intestinal organoids may provide a specific and robust model for this population.

Intestinal dysbiosis increases susceptibility to infection through the alteration of metabolic profiles, which increases morbidity. Zinc (Zn) homeostasis in mammals is tightly regulated by 24 Zn transporters. ZIP8 is unique in that it is required by myeloid cells to maintain proper host defense against bacterial pneumonia. In addition, a frequently occurring ZIP8 defective variant (SLC39A8 rs13107325) is strongly associated with inflammation-based disorders and bacterial infection. In this study, we developed a novel model to study the effects of ZIP8-mediated intestinal dysbiosis on pulmonary host defense independent of the genetic effects.
