Tobacco cessation interventions for young people.

Background: Most tobacco control programmes for adolescents are based around prevention of uptake, but teenage smoking is still common. It is unclear if interventions that are effective for adults can also help adolescents to quit. This is the second update of a Cochrane review first published in 2006.

Heart failure in primary care: qualitative study of current management and perceived obstacles to evidence-based diagnosis and management by general practitioners.

Background: Chronic heart failure is a common clinical condition with high morbidity and mortality. Despite the evidence that appropriate treatment with angiotensin-converting enzyme inhibitors can improve morbidity, primary care studies show that patients with heart failure are incorrectly diagnosed and inadequately treated.

Aim: To explore general practitioners' accounts of their management of patients with heart failure and identify the perceived obstacles to diagnosis and management.
