Gene test aims at Reducing Unnecessary Angiograms

It’s not a perfect test. Yet researchers report a key step for the first gene test aimed at reducing unnecessary angiograms — expensive and somewhat risky procedures that hundreds of thousands of Americans have each year to check for clogged arteries.

A number of studies have found that while the absolute rate of suicide among bariatric surgery patients is quite low, it is still higher than the norm for the general population.

Details of the Study:

The latest study, which tracked deaths among Pennsylvania residents who underwent bariatric surgery, examined a longer period than previous research — up to 10 years following the procedure.
