Randomized Controlled TrialMidodrine and clonidine in patients with cirrhosis and refractory or recurrent ascites: a randomized pilot study.
Splanchnic arterial vasodilatation and subsequent activation of anti-natriuretic and vasoconstrictive mechanisms have an important role in cirrhotic ascites. The aim of this study was to evaluate the effects of midodrine, clonidine, and their combination on systemic hemodynamics, renal function, and control of ascites in patients with cirrhosis and refractory or recurrent ascites. ⋯ These results suggest that midodrine, clonidine, and their combination plus SMT improves the systemic hemodynamics without any renal or hepatic dysfunction, and is superior to SMT alone for the control of ascites. However, the combination therapy was not superior to midodrine or clonidine alone.

Comparative StudyAnti-tumor necrosis factor therapy is associated with infections after abdominal surgery in Crohn's disease patients.
Anti-tumor necrosis factor (anti-TNF) therapy effects on postoperative complications in Crohn's disease (CD) patients are unclear. We examined a retrospective cohort to clarify this relationship. ⋯ In a tertiary referral center, use of anti-TNF therapy in CD patients ≤8 weeks before intestinal resection or any intra-abdominal surgery was independently associated with increases in infectious and surgical complications.

Review Meta AnalysisEffect of comorbidity on mortality in patients with peptic ulcer bleeding: systematic review and meta-analysis.
By systematic review and meta-analysis, we sought to assess the impact of comorbidity on short-term mortality in patients with peptic ulcer bleeding (PUB). ⋯ Underlying comorbidity is consistently associated with increased mortality in patients with PUB. The number and type of comorbidities in patients with PUB should be carefully evaluated and factored into initial management strategies.

Increased risk of pneumonia among patients with inflammatory bowel disease.
Patients with inflammatory bowel disease (IBD) may be at increased risk for infections. We aimed to determine the pneumonia risk in IBD and how specific medications affect this risk. ⋯ Patients with IBD are at increased risk for pneumonia. Medications such as corticosteroids and narcotics are particularly associated with pneumonia in this population. An emphasis upon primary prevention of pneumonia through vaccination and reduction of risk factors is warranted.

White-matter microstructural changes in functional dyspepsia: a diffusion tensor imaging study.
Recent neuroimaging studies have identified brain microstructural changes in patients with functional gastrointestinal disorders, especially in irritable bowel syndrome. However, whether the microstructure is changed in patients with postprandial distress syndrome (PDS) remains elusive. Therefore, the present study was aimed to examine the white-matter (WM) microstructural changes in patients with PDS. ⋯ Our findings have provided preliminary evidence of WM microstructural changes in patients with PDS. Part of the changes could be accounted for by a higher level of psychosocial distress in the patient group.
