ReviewGut Microbiota and Energy Expenditure in Health and Obesity.
The contribution of intestinal bacterial strains (gut microbiota) to the development of obesity and obesity-related disorders is increasingly recognized as a potential diagnostic and pharmacologic target. Alterations in the intestinal bacterial composition have been associated with presence of chronic low-grade inflammation, a known feature of insulin resistance and type 2 diabetes mellitus. ⋯ Moreover, fecal transplantation studies in conjunction with fecal sampling in prospectively followed cohorts will help identify causally involved intestinal bacterial strains in human obesity. Results from these studies will lead to characterization of novel diagnostic markers as well as therapeutic strategies that aim to treat obesity and obesity-related disorders.

Irritable bowel syndrome (IBS) is the most prevalent and the best studied functional gastrointestinal disorder. The etiology and the pathogenesis of IBS are still not clear; however, recent studies have implicated a role for alterations in the intestinal microbiota (dysbiosis) in the pathophysiology of the disorder. ⋯ In addition, animal studies and a few recent human clinical studies have demonstrated that compositional changes in the intestinal microbiota in IBS are associated with relevant abnormal gastrointestinal and brain-gut axis functions that are often observed in patients with IBS. This article discusses points of interest from the current research on the microbiota-gut-brain interactions in IBS and highlights the relevance of the emerging data to our understanding of the disorder and the clinical implications for patients' care.

Randomized Controlled TrialAbdominal Paracentesis Drainage Does Not Increase Infection in Severe Acute Pancreatitis: A Prospective Study.
To demonstrate the relationship between abdominal paracentesis drainage (APD) and infectious complications in moderately severe acute pancreatitis (MSAP) or severe acute pancreatitis (SAP) patients. ⋯ Our results indicate that APD did not increase the infectious complications and infection-related mortality compared with the strategy without APD in patients with MSAP or SAP.
