Special Issue, Call for Submissions

Healthcare disparities in gastroenterology and hepatology

We are pleased to announce a special issue of Gastroenterology Research to be published in April 2022 focusing on "Healthcare disparities in gastroenterology and hepatology". Disparities in healthcare access and healthcare outcomes are pervasive and predominantly affect underserved and vulnerable populations. Highlighting research to better identify and understand the factors contributing to healthcare disparities is of paramount importance to help guide future interventions to mitigate these healthcare disparities. We invite your submissions focused on all aspects of healthcare disparities in gastroenterology and hepatology.

Submission deadline: Feb 28, 2022
Publication: April 2022

  • Usefulness of the Eosinophilic Esophagitis Histologic Scoring System in Distinguishing Active Eosinophilic Esophagitis From Remission and Gastroesophageal Reflux Disease

    Eosinophilic esophagitis (EoE) is defined as esophageal dysfunction in the presence of > 15 intraepithelial eosinophils per high-power field (eos/hpf) in either the mid or distal esophagus. The current focus of EoE pathologic evaluation is the peak eosinophil count (PEC), although histologic features other than eosinophilic inflammation are also commonly observed.

  • Is the Use of Proton Pump Inhibitors a Predisposing Factor for Pyogenic Liver Abscesses?

    Proton pump inhibitors (PPIs) increase gastric pH by reducing acid production. The resulting alkaline milieu in the stomach increases the risk of bacterial translocation. This study aimed to investigate if there is a correlation between PPI use and developing pyogenic liver abscesses.

  • Clostridium difficile Infection Hospitalizations in the United States: Insights From the 2017 National Inpatient Sample

    There is a paucity of contemporary national estimates for Clostridium difficile infection (CDI) hospitalizations by age group, sex, and region in the US population. Also, there is lack of contemporary national statistics on CDI hospitalizations with comorbidities.

  • Characterization of Chronic Gastritis in Lynch Syndrome Patients With Gastric Adenocarcinoma

    Gastric cancer is one of the Lynch syndrome (LS)-associated malignancies. Previous studies have suggested that LS patients with gastric cancer also had chronic atrophic gastritis in the background mucosa, but further histologic characterization was not attempted.

  • Cirrhosis Is Associated With Worse Outcomes in Ischemic Colitis: A Nationwide Retrospective Study

    Ischemic colitis (IC) occurs when the blood supply of the large intestine becomes compromised. Cirrhosis is a disease entity in which there is a delicate balance between pro-coagulant and anti-coagulant states. Our aim was to examine the impact cirrhosis has on outcomes in patients with ischemic colitis.




A Focused Review on Recent Advances in the Diagnosis and Treatment of Viral Hepatitis
The global burden of viral hepatitis remains substantial despite advances in antiviral therapy and effective vaccines. There are five hepatitis viruses (hepatitis A, B, C, D, and E). Mortality related to hepatitis B virus and hepatitis C virus infections is among the top four global infectious diseases, together with human immunodeficiency virus infection, malaria, and tuberculosis.

Non-Invasive Assessment of Liver Fibrosis and Steatosis in End-Stage Renal Disease Patients Undergoing Renal Transplant Evaluation
Non-alcoholic fatty liver disease (NAFLD) has an increased prevalence in end-stage renal disease (ESRD) due to similar risk factors. The aim of this study was to assess non-invasive testing including transient elastography (TE) for liver stiffness (LS), controlled attenuated parameter (CAP) for steatosis, Fibrosis-4 (FIB-4) score...

Colonic Ganglioneuroma: A Rare Lesion With Extremely Different Presentations and Outcomes in Two Patients
Ganglioneuroma (GN) of the gastrointestinal tract is an extremely rare neuroectodermal tumor. Patients with ganglioneuromas have different presentations depending on the location, extent and size of the lesion. We present two cases of ganglioneuromas that had different clinical presentations and outcomes. Full Text
