Second hand smoke exposure slashed after three months of smokefree England

Hospitality workers' exposure to harmful second hand smoke has fallen by 95 per cent since smokefree workplaces were introduced in England on 1 July 2007, according to new research revealed at the National Cancer Research Institute Conference in Birmingham on the three month anniversary of smokefree England.

Rosiglitazone and Pioglitazone increase risk of congestive heart failure but not the risk of cardiovascular death

Patients with type 2 diabetes* or prediabetes* are more likely to develop congestive heart failure (CHF) when given rosiglitazone or pioglitazone, as compared with controls. However these drugs did not increase the risk of cardiovascular death (CVD) for these patients.

Researchers discover one of the mechanisms that prevents the spread of colon cancer

The first step in the development of colon cancer is the formation of benign tumours, called adenomas, in the intestine. Over time, these tumours may progress to produce colon cancer if they undergo a series of mutations and genetic alterations.
