Gastric polyps: a retrospective cohort analysis of 23,668 endoscopies indicates changing epidemiological and phenotypic characteristics.

Introduction: Growing adoption of endoscopic procedures in clinical practice has gradually increase the detection rate of gastric polypoid lesions.

Aim: To identify the epidemiologic characteristics of gastric polyps as well as changes of these parameters during a 15-year period.

Material And Methods: We reviewed all the upper endoscopies archived in our database reporting a polypoid lesion from 2003 to 2018.

Ulcerative colitis after SARS-CoV-2 infection.

Although severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) affects mainly the respiratory system, the gastrointestinal tract is also considered a site of viral activity. We hereby present the case of a 74-year-old male patient with the diagnosis of new-onset ulcerative colitis. One month earlier, the patient presented fever, running nose, and diarrhea and was tested positive for SARS-CoV-2.

Lipidomics in non-alcoholic fatty liver disease.

Non-alcoholic fatty liver disease (NAFLD), the most common chronic liver disorder in Western countries, comprises steatosis to nonalcoholic steatohepatitis (NASH), with the latter having the potential to progress to cirrhosis. The transition from isolated steatosis to NASH is still poorly understood, but lipidomics approach revealed that the hepatic lipidome is extensively altered in the setting of steatosis and steatohepatitis and these alterations correlate with disease progression. Recent data suggest that both quantity and quality of the accumulated lipids are involved in pathogenesis of NAFLD.
