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.

  • Development of a Predictive Model for Common Bile Duct Stones in Patients With Clinical Suspicion of Choledocholithiasis: A Cohort Study

    Current choledocholithiasis guidelines heavily focus on patients with low or no risk, they may be inappropriate for populations with high rates of choledocholithiasis. We aimed to develop a predictive scoring model for choledocholithiasis in patients with relevant clinical manifestations.

  • Proton Pump Inhibitors Use and Increased Risk of Spontaneous Bacterial Peritonitis in Cirrhotic Patients: A Retrospective Cohort Analysis

    Since their introduction in the early 1980s, proton pump inhibitors (PPIs) have been used worldwide for a broad range of indications. Unfortunately, however, PPIs have become overly prescribed by healthcare providers, sometimes in the absence of clear indications.

  • Acute Upper Gastrointestinal Bleeding: Less Severe Bleeding in More Frail and Older Patients, Comparison Between Two Time Periods Fifteen Years Apart

    Acute upper gastrointestinal bleeding (AUGIB) remains a common medical emergency with considerable morbidity and mortality. The aim of this study was to describe the patient characteristics, diagnoses and clinical outcomes of patients presenting with AUGIB nowadays and compare these with those of patients 15 years ago.

  • 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.

Rates, Reasons, and Independent Predictors of Readmissions in Portal Venous Thrombosis Hospitalizations in the USA
Portal vein thrombosis (PVT), generally considered rare, is becoming increasingly recognized with advanced imaging. Limited data exist regarding readmissions in PVT and its burden on the overall healthcare cost. Full Text

Key Clinical Image

Flood Syndrome
Flood syndrome refers to the exsanguination of ascitic fluid following the spontaneous rupture of an umbilical hernia, and is a rare complication of liver cirrhosis with ascites. In this case report, we describe a 67-year-old patient with Flood syndrome who was initially managed conservatively in a community hospital run by primary care physicians, prior to transfer to a tertiary hospital for specialist surgical review and management.
