A new study by researchers at the Johns Hopkins Center for Gun Policy and Research finds that the number of guns that were subsequently linked to crime sold by Badger Guns & Ammo, a Milwaukee-area gun shop, increased dramatically after Congress adopted measures likely to reduce the risks gun dealers face if they divert guns to criminals. The study is the first to examine the impact of these amendments on the diversion of guns to criminals and was recently published online in the peer-reviewed Journal of Urban Health.

Your risk of heart attack may increase during the days and weeks after the death of a close loved one, according to research reported in Circulation: Journal of the American Heart Association.

A study of 1,985 adult heart attack survivors showed that after a significant person's death, heart attack risks:

Acute kidney injury (AKI) has severe consequences, with a 25 to 80 percent risk of in-hospital death. Researchers have found a way to diagnose AKI using a urine test, enabling emergency departments to identify these high-risk patients when they first arrive at the hospital. The study will be published online on January 9, 2012, in the Journal of the American College of Cardiology.

CHICAGO – A substantial proportion of emergency department eye care in Florida is reimbursed through Medicaid or paid for out of pocket by patients, and those findings may help in strategic planning as the debate over how best to implement the nation's new health care reform law progresses, according to a study published in the Archives of Ophthalmology, one of the JAMA/Archives journals.

CHICAGO – Replacing visual acuity screenings for new Medicare enrollees with coverage of a dilated eye exam for healthy patients entering the government insurance program for the elderly "would be highly cost-effective," suggests a study being published Online First by the Archives of Ophthalmology, one of the JAMA/Archives journals.

BOSTON – A person's risk of suffering a heart attack increases by approximately 21 times in the first 24 hours after losing a loved one, according to a study lead by researchers at Beth Israel Deaconess Medical Center.

The study published Jan. 9 online in the journal Circulation found the risk of heart attack remained eight times above normal during the first week after the death of a loved one, slowly declining, but remaining elevated for at least a month.

OAK RIDGE, Tenn -- The prospect of electronics at the nanoscale may be even more promising with the first observation of metallic conductance in ferroelectric nanodomains by researchers at Oak Ridge National Laboratory.

Ferroelectric materials, which switch their polarization with the application of an electric field, have long been used in devices such as ultrasound machines and sensors. Now, discoveries about ferroelectrics' electronic properties are opening up possibilities of applications in nanoscale electronics and information storage.

CHICAGO -- A 2010 outbreak of Legionnaires' disease in Wisconsin has been linked to a decorative fountain in a hospital lobby, according to a study published in the February issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America.

Philadelphia, PA, January 9, 2012 – New research reveals that insulin applied in therapeutic doses selectively stimulates the formation of new elastic fibers in cultures of human aortic smooth muscle cells. These results advance the understanding of the molecular and cellular mechanisms of diabetic vascular disease. The study is published in the February issue of the American Journal of Pathology.

COLUMBIA, Mo. – As the U.S. economy continues to lag, many investors remain wary about taking risks with the stock market. Now, researchers at the University of Missouri have concluded that this attitude toward investment risk-taking is influenced by the age of the investor and the economic climate of the time period. Rui Yao, an assistant professor of personal financial planning in the College of Human Environmental Sciences at MU, found that willingness to take financial risks, or "risk tolerance," decreases as investors age.

A Rush University Medical Center led international research team has announced that a treatment to prevent bleeding episodes in children with hemophilia A also is effective for adolescents and adults.

Researchers have found clear associations between marijuana use in young males and cyclic vomiting syndrome (CVS), where patients experience episodes of vomiting separated by symptom free intervals.

The study, published in the January issue of Neurogastroenterology and Motility, looked at 226 patients seen at the Mayo Clinic in Rochester, New York, USA, over a 13-year period.

A registry -which includes every patient in Sweden having percutaneous coronary intervention (PCI) for the treatment of acute and stable coronary artery disease- has found that PCI implantations using a new generation of drug-eluting stents is associated with lower rates of relapse (restenosis), stent thrombosis and subsequent mortality than older generation drug-eluting stents and bare-metal stents.(1)

Reston, Va. (December 28, 2011) – In a new review of imaging studies spanning more than ten years, scientists find that a method of positron emission tomography (PET) safely and accurately detects dementia, including the most common and devastating form among the elderly, Alzheimer's disease. This research is featured in the January issue of the Journal of Nuclear Medicine.

Insurance status doesn't affect the quantity (or value) of imaging services received by patients in a hospital, in-patient setting, according to a study in the January issue of the Journal of the American College of Radiology.

Approximately 51 million Americans, or 16.7 percent of the population, were without health insurance for some or all of 2009. Lack of insurance is associated with less preventive care, delays in diagnosis and unnecessary deaths.
