Quality standards for the management of non-alcoholic fatty liver disease (NAFLD): consensus recommendations from the British Association for the Study of the Liver and British Society of Gastroenterology NAFLD Special Interest Group.

Non-alcoholic fatty liver disease (NAFLD) is common, affecting approximately 25% of the general population. The evidence base for the investigation and management of NAFLD is large and growing, but there is currently little practical guidance to support development of services and delivery of care. To address this, we produced a series of evidence-based quality standard recommendations for the management of NAFLD, with the aim of improving patient care.

Low-dose acetaminophen induces early disruption of cell-cell tight junctions in human hepatic cells and mouse liver.

Dysfunction of cell-cell tight junction (TJ) adhesions is a major feature in the pathogenesis of various diseases. Liver TJs preserve cellular polarity by delimiting functional bile-canalicular structures, forming the blood-biliary barrier. In acetaminophen-hepatotoxicity, the mechanism by which tissue cohesion and polarity are affected remains unclear.

Hepatic stellate cells: central modulators of hepatic carcinogenesis.

Hepatocellular carcinoma (HCC) represents the second most common cause of cancer-related death worldwide, and is increasing in incidence. Currently, our therapeutic repertoire for the treatment of HCC is severely limited, and therefore effective new therapies are urgently required. Recently, there has been increasing interest focusing on the cellular and molecular interactions between cancer cells and their microenvironment.

Genetics of ulcerative colitis.

Ulcerative colitis (UC) and Crohn's disease (CD) are related polygenic inflammatory bowel diseases (IBDs), with distinct and overlapping susceptibility loci. Recently, hypothesis-free genome-wide association (GWA) studies have revolutionized the field of complex disease genetics. Substantial advances have been achieved in defining the genetic architecture of IBD.

Video-assisted thoracoscopic surgery management of spontaneous pneumothorax--long-term results.

Objective: Although widely adopted, there is lack of immediate and long-term follow-up data for patients undergoing video-assisted thoracoscopic surgery (VATS) management of pneumothorax. Therefore, we have reviewed our experience with both primary (PSP) and secondary (SSP) spontaneous pneumothorax to assess the perioperative outcomes and long-term efficacy associated with different VATS operative strategies.

Methods: A retrospective case series review was undertaken on all patients undergoing VATS procedures for PSP or SSP over a 17-year period.
