ReviewAntacids for preventing oesophagogastric variceal bleeding and rebleeding in cirrhotic patients.
Ruptured gastroesophageal varices are the most severe and frequent cause of gastrointestinal bleeding in cirrhotic patients, leading to death in 5% to 8% of patients during the first 48 hours and oesophagogastric varices account for 60% to 80% of first bleeding in patients with portal hypertension. Antacids are often used for emergency treatment of bleeding oesophageal varices in patients with cirrhosis of the liver. ⋯ it is not possible to determine whether antacids are beneficially effective or harmful for preventing oesophagogastric variceal bleeding and rebleeding in cirrhotic patients since randomised clinical trials investigating it are lacking.

There is increasing evidence that capillary occlusion plays an important part in the development of diabetic retinopathy. Disaggregants, such as pentoxyfilline may influence the outcome and progression of diabetic retinopathy, but no systematic review of the literature on its efficacy and safety has been published to examine this hypothesis. ⋯ No sound research to date has examined the treatment of diabetic retinopathy with pentoxyfilline in such a way as to indicate whether this form of intervention has a significant impact on the natural history of this clinical condition. The potential role of this substance in the treatment of diabetic retinopathy remains open to debate, and it is suggested that future research focusing on patient-relevant outcomes takes the opportunity of addressing this important issue directly.

Review Meta AnalysisInformation provision for stroke patients and their caregivers.
Research shows that stroke patients and their families are dissatisfied with the information provided and have a poor understanding of stroke and associated issues. ⋯ There is evidence that information improves patient and carer knowledge of stroke, aspects of patient satisfaction, and reduces patient depression scores. However, the reduction in depression scores was small and probably clinically insignificant. Although the best way to provide information is still unclear there is some evidence that strategies that actively involve patients and carers and include planned follow up for clarification and reinforcement have a greater effect on patient mood.

Healthcare professionals frequently advise patients to improve their health by stopping smoking. Such advice may be brief, or part of more intensive interventions. ⋯ Simple advice has a small effect on cessation rates. Assuming an unassisted quit rate of 2 to 3%, a brief advice intervention can increase quitting by a further 1 to 3%. Additional components appear to have only a small effect, though there is a small additional benefit of more intensive interventions compared to very brief interventions.

Review Meta AnalysisInterventions for treating collagenous colitis.
Collagenous colitis is a cause of chronic diarrhea. Treatment has been based mainly on anecdotal evidence. This review was performed to identify therapies for collagenous colitis that have been proven in randomized trials. ⋯ Budesonide is effective for inducing and maintaining clinical and histological response in patients with collagenous colitis. The evidence for benefit with bismuth subsalicylate and for mesalamine with or without cholestyramine is weak. There is no evidence for the effectiveness of Boswellia serrata extract, prednisolone, or probiotics. These agents and other therapies require further study.
