Obese women who have recently given birth appear to be twice as likely as women of normal weight to have a heart attack or a stroke. HealthDay says researchers were able to prove a strong association between obesity and increased risk – although not a cause-and-effect relationship – even though heart attacks and strokes among this age group are rare.

Another finding about maternal obesity: Research appearing in Paediatric and Perinatal Epidemiology says the children of mothers who are obese before becoming pregnant have a risk of frequent wheezing that's around four times higher than children whose mothers are a normal weight. Frequent wheezing is one of the symptoms of asthma.

The vaccine that preschool-age children get to protect them against whooping cough may start losing its effectiveness a few years later, says a new study. Reuters reports that experts think the cause can be traced back to the '90s, when doctors switched the whooping cough vaccine to one that worked well in the short-term but perhaps offered less long-term protection.

England's chief medical officer says antibiotic resistance poses a "catastrophic threat," reports the Huffington Post – one that requires a global, collaborative effort to develop new medications that can treat new, emerging, stronger infections. Failing that, said the health British official, in as little as 20 years anybody undergoing "minor surgery" could "die because of an ordinary infection" that's resistant to antibiotics.

Older women in a new study who took aspirin regularly had a risk of developing a deadly skin cancer that was 21 percent lower than people who don't take the medicine. U.S. News & World Reports said while a clinical trial is needed to firm up the findings, researchers also found that the longer postmenopausal women take aspirin, the smaller their risk of cancer becomes.

A class of diabetes medication known as GLP-1s has been linked to an increased risk of pancreatitis, but new research that was presented at the American College of Cardiology's annual Scientific Sessions (press release) says it also may reduce users' risk of heart failure. Further study will be needed, said researchers.

And finally: You may be feeling that hour you lost early Sunday morning, and you certainly wouldn't be alone in that. The Los Angeles Times says the Monday after spring daylight saving time kicks in is "one of the most dangerous days of the year," citing increased likelihood of traffic accidents, workplace accidents and even heart attacks.
