Stem cells used to learn how common mutation in Asians affects heart health

Stem cells used to learn how common mutation in Asians affects heart health

Over 500 million people worldwide carry a genetic mutation that disables a common metabolic protein called ALDH2. The mutation, which predominantly occurs in people of East Asian descent, leads to an increased risk of heart disease and poorer outcomes after a heart attack. It also causes facial flushing when carriers drink alcohol. Continue reading

Better way to track emerging cell therapies using MRIs

Better way to track emerging cell therapies using MRIs

Cellular therapeutics — using intact cells to treat and cure disease — is a hugely promising new approach in medicine but it is hindered by the inability of doctors and scientists to effectively track the movements, destination and persistence of these cells in patients without resorting to invasive procedures, like tissue sampling.

Responsible use of x-rays in dentistry for children

Responsible use of x-rays in dentistry for children

Children need smaller portions — this is true when it comes to eating meals, and when addressing topics such as imaging. Continue reading

Imaging identifies asymptomatic people at risk for stroke

Imaging identifies asymptomatic people at risk for stroke

Imaging can be a cost-effective way to identify people at risk for stroke who might benefit from aggressive intervention, according to a new modeling study published online in the journal Radiology . The study looked at people with asymptomatic carotid artery stenosis, a narrowing of the major blood vessels supplying blood to the head due to atherosclerosis, or plaque buildup. Carotid artery stenosis is the primary cause of up to 20 percent of ischemic strokes, which result from an obstruction within a blood vessel and make up 85 percent of all strokes. Continue reading

New statin guidelines an improvement, study shows

New statin guidelines an improvement, study shows

New national guidelines can improve the way statin drugs are prescribed to patients at risk for cardiovascular disease, a Yale University study has found. The research, published Aug. 25 in the Journal of the American College of Cardiology , also showed the new guidelines produce only a modest increase in the number of patients being given the drugs Continue reading

Hospitals could face penalties for missing electronic health record deadline

Hospitals could face penalties for missing electronic health record deadline

Many of the nation’s hospitals struggled to meet a federally mandated electronic health records deadline, and as a result could collectively face millions of dollars in reduced Medicare payments this year, a University of Michigan study shows. More than half of U.S. hospitals were on the hook to meet a new set of “meaningful use” of electronic health records criteria — known as the stage 2 criteria — by the end of the fiscal year that ended in July Continue reading

Pictures in five seconds: Digital x-ray imaging

Pictures in five seconds: Digital x-ray imaging

Wanting to replace the medical equipment for taking X-rays, the Mexican Society of Radiology (CMR) created a system of digital x-ray imaging, which replaces the traditional plaque by a solid detector, which delivers results in five seconds. Continue reading

Mammography benefits women over 75, new study finds

Mammography benefits women over 75, new study finds

Mammography-detected breast cancer is associated with a shift to earlier stage diagnosis in older women, subsequently reducing the rate of more advanced, difficult-to-treat cases, according to a new study published online in the journal Radiology . Researchers said the findings lend support to regular mammography screening in women ages 75 and older Continue reading

Mammography benefits women over 75, new study finds

Mammography-detected breast cancer is associated with a shift to earlier stage diagnosis in older women, subsequently reducing the rate of more advanced, difficult-to-treat cases, according to a new study published online in the journal Radiology . Researchers said the findings lend support to regular mammography screening in women ages 75 and older. The value of mammography screening in older women has been subject to much debate in recent years. Continue reading

Eating baked, broiled fish weekly boosts brain health, study says

Eating baked, broiled fish weekly boosts brain health, study says

Eating baked or broiled fish once a week is good for the brain, regardless of how much omega-3 fatty acid it contains, according to researchers at the University of Pittsburgh School of Medicine. The findings, published online recently in the American Journal of Preventive Medicine , add to growing evidence that lifestyle factors contribute to brain health later in life. Scientists estimate that more than 80 million people will have dementia by 2040, which could become a substantial burden to families and drive up health care costs, noted senior investigator James T Continue reading
