Just one or two experiences with marijuana may alter teen brains

Teens who use pot just one or two times may end up with changes to their brains, a new study finds.

There were clear differences on brain scans between teens who said they had tried cannabis a couple of times and those who completely eschewed the drug, researchers reported in the Journal of Neuroscience.

"Research using animals to study the effects of cannabis on the brain have shown effects at very low levels, so we had reason to believe that brain changes might occur at even the earliest stages of cannabis use," Orr said in an email.

With an estimated 35% of US teens using cannabis, the new findings are concerning, the researchers noted.

Too little sleep tied to increased heart disease risk

People who sleep less than six hours a night may be more likely to develop cardiovascular disease than those who sleep seven to eight hours, a Spanish study suggests.

Researchers found that compared to people who got seven to eight hours of sleep, those who slept less than six hours a night were 27% more likely to have "preclinical" atherosclerosis: structural changes and thickening in the artery walls that is not yet serious enough to cause complications.

Previous research has linked lack of sleep to traditional risk factors for heart disease like high blood sugar, high blood pressure, inflammation and obesity.

Centre to manage infectious diseases to be fully operational by May

A state-of-the-art national centre for managing infectious diseases is set to be fully operational by May.

The 330-bed National Centre for Infectious Diseases (NCID) is designed to manage an outbreak on the scale of the severe acute respiratory syndrome in 2003, said its executive director Leo Yee Sin, at a media briefing yesterday.

The NCID takes over the functions of Tan Tock Seng Hospital's Communicable Disease Centre (CDC), which closed on Dec 13 last year. Since then, the NCID has been treating patients at its outpatient clinic.

A key feature of the centre is its high-level isolation unit (HLIU) for treating high-risk pathogens, including haemorrhagic fevers caused by the Ebola virus, as well as biothreat agents such as anthrax.
