Restless legs ups heart disease, stroke risk
December 31, 2007 05:56 PM - Reuters

NEW YORK (Reuters Health) - People with restless legs syndrome, or RLS, are twice as likely as those without RLS to suffer a stroke or heart disease, and the risk is greatest in those with the most frequent and severe symptoms, according to the results of a large study. RLS is a movement disorder that causes uncomfortable sensations in the legs that worsen when a person is inactive, such as during sleep. This is not the first study to link RLS with cardiovascular disease, the study team notes in the January 1st issue of the journal Neurology. However, the prior two studies that supported an association did not use current RLS diagnostic criteria and one of them included only men.

BERLIN/PARIS (Reuters) - For years, anyone needing a nicotine fix in a German pub or French cafe didn't even have to light up -- the air was already so full of smoke that they only had to open their mouth and inhale. But that all changes on Tuesday when strict new bans take effect in two of Western Europe's final bastions for smokers, Germany and France. There was long and fierce resistance to the prohibitions on tobacco that other countries imposed.

DURHAM, N.C. - Contrary to previous studies, married patients with lung cancer do not have longer survival, according to analysis of an extensive Mayo Clinic database in the December issue of "The Oncologist." However, the results suggest some other potentially important differences among patient subgroups -- including the possibility that married patients receive a more aggressive approach to lung cancer treatment, write Dr. Aminah Jatoi and colleagues.
