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 October 2021 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: August 31, 2021
Publication: October 2021

  • 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.

  • Capsule Endoscopy Versus Colonoscopy in Patients With Previous Colorectal Surgery: A Prospective Comparative Study

    Colonic capsule endoscopy (CCE) derived from the video capsule endoscopy, initially proposed to explore the small bowel, has demonstrated high sensitivity and specificity for colonic polyp detection. The primary outcome of the study was to assess the safety, feasibility, and reliability of CCE after colorectal surgery.




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.

Efficacy and Safety of Neostigmine and Decompressive Colonoscopy for Acute Colonic Pseudo-Obstruction: A Single-Center Analysis
ACPO is characterized by acute colonic dilation in the absence of anatomical obstruction. Neostigmine is an acetylcholinesterase inhibitor recommended as first-line salvage therapy for uncomplicated ACPO. Decompressive colonoscopy is recommended if neostigmine is contraindicated or unsuccessful. Full Text

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
