COVID-19 and Long COVID

COVID-19 and Post COVID-19 Condition (Long COVID)
The COVID-19 outbreak presents the unprecedented challenge for world public and medical practitioners and health care providers, the post COVID-19 condition (or long COVID) includes long term symptoms which may persist for months or years after SARS-CoV-2 infection. We will consider submissions related to all aspects of COVID-19 and Long COVID, and process the manuscripts in priority.
Collection of COVID-19 articles.


  • The Incidence of Venous Thromboembolism and Practice of Deep Venous Thrombosis Prophylaxis Among Hospitalized Cirrhotic Patients

    Patients with liver cirrhosis have altered hepatic synthetic functions which theoretically result in reduced levels of pro-and anti-coagulant factors as well as thrombocytopenia. Initially, cirrhotic patients were thought to be at an increased risk of bleeding and a reduced risk of thrombosis.

  • Clinical Outcomes and Predictors of Thirty-Day Readmissions of Hypertriglyceridemia-Induced Acute Pancreatitis

    Hypertriglyceridemia (HTG) is a well-established cause of acute pancreatitis often leading to significant morbidity, mortality, and healthcare burden. This study aimed to describe the rate, reasons, and predictors of HTG-induced acute pancreatitis (HTG-AP) in the USA.

  • Corticosteroid and Biologic Use Not Associated With Adverse Outcomes for Inflammatory Bowel Disease Patients Hospitalized With COVID-19

    To date, studies investigating the inflammatory bowel disease (IBD) patient experience with coronavirus disease 2019 (COVID-19) have consistently reported that the observed rate of COVID-19 within this population is similar to the general population.

  • Cross-Sectional Study of Swallowing Phases in Cases of Megaesophagus Caused by Chagas Disease

    Chagas disease, caused by the flagellate protozoan Trypanosoma cruzi, is an infectious cause of secondary achalasia and megaesophagus. Moreover, the oral and pharyngeal phases of swallowing may also be affected, which may contribute to dysphagia and increase the possibility of airway aspiration during and/or after swallowing.

  • 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.




Video Capsule Endoscopy in Gastroenterology
Video capsule endoscopy (VCE) is a wireless technology used by gastroenterologists for various indications in their clinical practice. There has been significant improvement in this technology since its start about two decades ago. Specific video capsules have been made to evaluate the small bowel, colon, and esophagus.
