Here's a look at some of the top health news being talked about around the U.S. and the world today:

• Slings worn by adults for carrying infants could carry an unreasonable risk of suffocation to the infant, the federal government is warning. The Consumer Product Safety Commission has received reports of about a dozen children who have died in the past 20 years due to suffocation and is reviewing the design of all slings, ABC News reported. In the meantime, it is cautioning all parents who use a sling.

The video below, produced by CBS News, gives a better idea of the risks being reviewed.

• Americans — including President Barack Obama — are demanding too many tests, too much screening and too many procedures, according to an editorial in the Archives of Internal Medicine published this month. The Associated Press reported that the belief that Americans are being overtreated is a growing sentiment in the health-care arena, prompting questions about widespread recommendations for prostate and breast cancer screening in recent months.

• Older patients are more likely to receive inappropriate medications when they are treated in an emergency room, a recent University of Michigan study found. A handful of medications are the most common medications that have more potential problems than potential benefits for older patients, it was reported on All Headline News.

• A new genetic test may be more effective at identifying abnormalities that would predispose a child to autism than standard genetic tests, the Palm Beach Post reported today.

• Aggressive treatment strategies that were expected to prevent heart attacks among Type 2 diabetics actually turned out to be ineffective or even harmful, according to new studies. Those strategies - treating patients to get their blood pressure to a normal range, raising levels of good cholesterol, lowering triglyceride levels or modulating sharp upswings in blood sugar after a meal - are now being questioned, the New York Times reported.
