Helicobacter pylori-derived outer membrane vesicles stimulate interleukin 8 secretion through nuclear factor kappa B activation.

Background/aims: Bacteria-derived outer membrane vesicles (OMVs) are commonly associated with various biological activities and functions. Helicobacter pylori-derived OMVs are thought to contribute to pathogenesis. This study aimed to investigate the effects of H.

The Fatty Liver Index: A Simple and Accurate Predictor of Colorectal Adenoma in an Average-Risk Population.

Background: Nonalcoholic fatty liver disease, the hepatic manifestation of metabolic syndrome, is associated with increased risk of colorectal adenoma, a precursor of colorectal cancer. Because nonalcoholic fatty liver disease and colorectal adenoma share many common risk factors of metabolic syndrome, the association between these 2 pathological findings has been investigated in multiple studies, but the results have been conflicting.

Objective: The present study aimed to assess the relationship between the fatty liver index, a predictor of nonalcoholic fatty liver disease, and the prevalence of colorectal adenomas.

Abdominal Visceral to Subcutaneous Adipose Tissue Ratio Is Associated with Increased Risk of Erosive Esophagitis.

Background: To investigate the association between abdominal fat distribution represented by the visceral fat area (VFA) to subcutaneous fat area (SFA) ratio, and erosive esophagitis (EE).

Methods: Seven hundred and twenty-eight participants aged >40 years underwent physical examination, blood tests, esophagogastroduodenoscopy, and abdominal computer tomography at Chung-Ang University Hospital from 2007 to 2012.

Results: Of 728 subjects, 65 (8.

Acute Gastric Injury Caused by Undissolved Sodium Picosulfate/Magnesium Citrate Powder.

Sodium picosulfate/magnesium citrate (SPMC) is a widely used oral bowel cleansing agent considered to be relatively safe. However, partially dissolved or undissolved SPMC powder may cause severe injuries of the esophagus and stomach. We report a very rare case of acute gastric injury without esophageal damage caused by the ingestion of undissolved SPMC powder.

[Risk factors for multidrug-resistant tuberculosis in the city of Kinshasa in the Democratic Republic of Congo].

Background: The aim of this study was to determine the risk factors for multidrug-resistant tuberculosis (TB) in the city of Kinshasa in the Democratic Republic of Congo.

Methods: This was a case control study. The cases included all TB patients notified as resistant to rifampicin and isoniazid in Kinshasa from January 2012 to June 2013.
