Barrett's Esophagus As A Premalignant Condition; Medical And Surgical Therapeutic Management, Vlad Denis Constantin, Adrian Silaghi, Laura Florentina Rebegea, Stana Paunica, Anca Silvia Dumitriu, Doina Andrada Mihai, Ioana Paunica, Dragos Epistatu

Journal of Mind and Medical Sciences

Barrett's esophagus (BE) represents a special clinical entity, which may have reduced symptoms, but an increased potential for malignant degeneration. The factors that lead to the appearance of Barrett's esophagus are multiple, the most important being gastro-esophageal reflux, as well as smoking and obesity. BE occurs as a result of damage of the esophageal mucosa, caused by acid/basic gastroesophageal reflux and resulting in the transformation of the epithelium from squamous to intestinal type. The diagnosis of BE is primarily based on endoscopic examination. This method has not only a diagnostic role, but also a therapeutic one through the minimally invasive …


A Case Report And A Review Of Pediatric Hepatoblastoma, Anthony D. Derenzi, Audrey Bowen Oct 2023

A Case Report And A Review Of Pediatric Hepatoblastoma, Anthony D. Derenzi, Audrey Bowen

HCA Healthcare Journal of Medicine

Introduction

Hepatoblastoma is a rare pediatric cancer. Approximately 100 cases of hepatoblastoma are reported per year. Due to the limited incidence of this disorder an internationally agreed- upon criteria was developed to classify patients as standard or high-risk. Studies involving chemotherapeutic agents, surgery, and liver transplants have been demonstrated to improve the disease-free survival rate. The combination of chemotherapeutic agents and surgery demonstrated the ability of these regimens to downgrade the initial diagnostic staging of tumors and transform previously unresectable tumors into resectable tumors.

Case Presentation

The following case of hepatoblastoma presents a 4-year-old male who presented to the emergency …

Proton Pump Inhibitor Use And Adverse Effects In South Atlantic Hospitals, Nicholas D'Angelo, Ramyar Sigarchy, Anthony Esswein, Sidra Asrar

HCA Healthcare Journal of Medicine

Background

Proton pump inhibitors (PPI) have transformed the management of acid-related gastrointestinal disorders, becoming one of the top-selling medications in the United States. There is no doubt that PPIs have a significant therapeutic impact on patients with gastroesophageal reflux disease and gastrointestinal bleeding. However, evidence is mounting that PPIs are overprescribed, leading to more patients possibly experiencing adverse effects. There is a great deal of ongoing debate surrounding the significance and impact of these adverse effects.

Methods

We conducted a study in 9 HCA hospitals in the southeastern United States to determine the number of patients who started on PPIs …

Metastatic colorectal cancer (mCRC) with mutated BRAF exhibits distinct biological and molecular features that set it apart from other subtypes of CRC. Current standard treatment for these tumors involves a combination of chemotherapy (CT) and VEGF inhibitors. Recently, targeted therapy against BRAF and immunotherapy (IT) for cases with microsatellite instability (MSI) have been integrated into clinical practice. While targeted therapy has shown promising results, resistance to treatment eventually develops in a significant portion of responsive patients. This article aims to review the available literature on mechanisms of resistance to BRAF inhibitors (BRAFis) and potential therapeutic strategies to overcome them.

Manuscripts, Articles, Book Chapters and Other Papers

The management of pediatric Peutz-Jeghers Syndrome (PJS) focuses on the prevention of intussusception complicating small intestinal (SI) polyposis. This hinges on the accurate appraisal of the polyp burden to tailor therapeutic interventions. Video Capsule Endoscopy (VCE) is an established tool to study SI polyps in children, but an in-depth characterization of polyp burden in this population is lacking. Methods: We performed a retrospective longitudinal cross-sectional analysis of VCE studies in pediatric PJS patients at our institution (CMKC) from 2010 to 2020. Demographic, clinical, and VCE findings reported by three reviewers in tandem were accrued. Polyp burden variables were modeled as …

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Cow's milk protein allergy (CMPA) is one of the most common types of food allergy in infants. Faecal pathogen cultures showed that the positive rate of Clostridium perfringens was more than 30%, which was significantly higher than that for other bacteria. Therefore, it is speculated that Clostridium perfringens colonization may be one of the pathogenetic factors for CMPA in infants. We conducted a real-world evidence study. Infants aged 0-6 months with diarrhoea and mucoid and/or bloody stools were recruited from a large tertiary hospital in China. Faecal pathogen cultures for the detection of Clostridium perfringens were confirmed by flight …

Tumor development relies on the stemness of cancer stem cells, which is regulated by environmental cues. Previous studies have shown that zyxin can inhibit the expression of genes for embryonic stem cell status. In the present study, the expression levels of zyxin protein in cancer tissues and adjacent noncancerous tissues from 73 gastric cancer patients with different clinical stages were analyzed by Western blot. We showed that the relative expression levels of zyxin in gastric cancer tissues (cancer tissues/adjacent tissues) were significantly downregulated in advanced clinical stages. Overexpression of zyxin inhibited the stemness and epithelial-mesenchymal transition (EMT) processes in gastric …

Elongation Of Very Long Chain Fatty Acids-3 (Elovl3) Is Activated By Zhx2 And Is A Regulator Of Cell Cycle Progression, Kate Townsend Creasy, Hui Ren, Jieyun Jiang, Martha L. Peterson, Brett T. Spear

Markey Cancer Center Faculty Publications

Zinc fingers and homeoboxes 2 (Zhx2) are transcriptional regulators of liver gene expression with key functions in embryonic development as well as tissue regeneration in response to damage and disease, presumably through its control of target genes. Previous microarray data suggested that elongation of very long chain fatty acids-3 (Elovl3), a member of the ELOVL family of enzymes that synthesize very long chain fatty acids (VLCFAs), is a putative Zhx2 target gene. VLCFAs are core component of ceramides and other bioactive sphingolipids that are often dysregulated in diseases and regulate key cellular processes including proliferation. Since several previously identified Zhx2 …

Background For pediatric patients with a diagnosis of inflammatory bowel disease (IBD), initiation of biologic therapy can be essential to attain disease control. Unfortunately, patients often experience delays in receiving the first dose of these medications due to the need for insurance companies to approve medication prior authorizations (PA). Physicians and support staff spend many working hours collating and transferring information regarding urgency to payors. To our knowledge, no studies exist to evaluate the factors that contribute to how quickly a medication is approved in pediatric patients. We set out here to evaluate which demographic and disease factors contribute to …

Faculty, Staff and Students Publications

BACKGROUND/AIMS: Medication non-adherence is a leading cause of transplant rejection, organ loss, and death; yet no rigorous controlled study to date has shown compelling clinical benefits from an adherence-improving intervention. Non-adherent patients are less likely to participate in trials, and therefore, most studies enroll a majority of adherent patients who do not stand to benefit from the intervention, as they do not have the condition (non-adherence) under investigation. The improving Medication Adherence in adolescent Liver Transplant recipients trial specifically targets non-adherent patients to investigate whether a remote intervention to improve adherence results in reduced incidence of biopsy-confirmed rejection.

METHODS: Improving …

BACKGROUND: Obesity is associated with an increased risk of developing cirrhosis. However, body mass index (BMI) and waist-to-hip ratio (WHR) may not be indicative of body composition parameters that predispose to cirrhosis. Bioimpedance analysis (BIA) is a noninvasive cost-efficient method for more detailed estimation of body composition.

METHODS: We examined patients with cirrhosis who underwent BIA as part of enrollment into a prospective cohort study. We examined the correlation between BIA variables, BMI, and WHR. We performed sex-adjusted and race-adjusted and race-specific multivariable logistic regression analyses to examine the association between anthropometric variables and risk factors [NAFLD, alcohol-associated liver disease …

Background: NAFLD can be associated with disease burden and stigma to patients and providers. Aims: To understand the disease burden and stigma related to NAFLD. Methods: Members of the Global NASH Council created two surveys (68-item patient and 41- items provider survey) about experiences and attitudes toward NAFLD and related terms. Results: The surveys were completed by 895 NAFLD patients (19 countries) and 629 providers (64% GI/hepatologists, 23 countries). Of all patients, 64% ever disclosed having NAFLD to family/friends; the main term used was “fatty liver” (82%) while “metabolic disease” or “MAFLD” were rarely used (never by 88%). 35% of …

Background: Pruritus—itching—is common with liver disease, but its prevalence and severity among US patients with chronic hepatitis B and C (HBV, HCV) are not well-documented. A subset of patients from the Chronic Hepatitis Cohort Study (CHeCS) were surveyed to examine pruritus prevalence, persistence, and management, and the impact on patients’ quality of life (QoL). Methods: The validated Pruritus Numeric Rating Scale (NRS) was used to assess pruritus intensity; patients who reported a score ≥ 3 in the last 30 days were invited to participate in a 6-month study using the validated SF-36 questionnaire. A general regression model (univariate followed by …

Background

European-specific policies for tuberculosis (TB) elimination require identification of key populations that benefit from TB screening.

Aim

We aimed to identify groups of foreign-born individuals residing in European countries that benefit most from targeted TB prevention screening.

Methods

The Tuberculosis Network European Trials group collected, by cross-sectional survey, numbers of foreign-born TB patients residing in European Union (EU) countries, Iceland, Norway, Switzerland and the United Kingdom (UK) in 2020 from the 10 highest ranked countries of origin in terms of TB cases in each country of residence. Tuberculosis incidence rates (IRs) in countries of residence were compared with countries …

BACKGROUND: Gastroparesis (GP) is characterized by delayed gastric emptying in the absence of mechanical obstruction.

OBJECTIVE: Genetic predisposition may play a role; however, investigation at the genome-wide level has not been performed.

METHODS: We carried out a genome-wide association study (GWAS) meta-analysis on (i) 478 GP patients from the National Institute of Diabetes and Digestive and Kidney Diseases Gastroparesis Clinical Research Consortium (GpCRC) compared to 9931 population-based controls from the University of Michigan Health and Retirement Study; and (ii) 402 GP cases compared to 48,340 non-gastroparesis controls from the Michigan Genomics Initiative. Associations for 5,811,784 high-quality SNPs were tested on …
