Regular, moderate, coffee drinking may reduce heart failure risk

If you drink coffee regularly in moderation, you could reduce your risk of heart failure, according to new research in the American Heart Association's journal Circulation Heart Failure.

Researchers, analyzing previous studies on the link between coffee consumption and heart failure, found that moderate coffee drinking as part of a daily routine may be linked with a significantly lower risk of heart failure. In contrast, indulging excessively may be linked with an increased chance of developing serious heart problems.

Clot-busting medicine safe for use in warfarin-treated patients following stroke

DURHAM, N.C.— The clot-busting medicine, tPA (tissue plasminogen activator), is safe to use in acute stroke patients already on the home blood thinner warfarin, according to researchers from Duke Clinical Research Institute (DCRI). This study helps allay previous concerns that tPA was too dangerous to use in patients on home anticoagulation and would lead to high risk for potentially fatal intracranial bleeding.

Progress in quest to reduce use of radiation in treatment of pediatric Hodgkin lymphoma

A multicenter trial showed that nearly half of young patients with early-stage Hodgkin lymphoma can be cured without undergoing either irradiation or intensive chemotherapy that would leave them at risk for second cancers, infertility, heart and other problems later.

Musical robot companion enhances listener experience

Wedding DJs everywhere should be worried about job security now that a new robot is on the scene.

Shimi, a musical companion developed by Georgia Tech's Center for Music Technology, recommends songs, dances to the beat and keeps the music pumping based on listener feedback.

The smartphone-enabled, one-foot-tall robot is billed as an interactive "musical buddy."

"Shimi is designed to change the way that people enjoy and think about their music," said Professor Gil Weinberg, director of Georgia Tech's Center for Music Technology and the robot's creator.

Health-care law gender gap

As the Supreme Court prepares to issue its ruling on Thursday, Americans are divided along party, ideology and gender lines on a key provision of the healthcare law.

A new National Agenda Opinion Poll by the University of Delaware's Center for Political Communication reveals women are significantly more likely to support health insurance requirements than men. Additionally, Democrats and liberals overwhelmingly favor insurance mandates, whereas large majorities of Republicans and conservatives oppose them.

Policies to discourage drug trafficking should account for complexity of 'the game'

CORVALLIS, Ore. – Drug traffickers who want to leave the "game" behind often struggle to do so because they fear loss of power and status, a new study shows.

Those who do leave the illegal drug trade often do so because of a complex mixture of issues including fatherhood, drug use and abuse, and threat of punishment by authorities or fear of retaliation. Researchers concluded that traffickers need ways that allow them to leave the drug business without surrendering their entire identity.

Moffitt Cancer Center researchers test drug combinations to prevent graft vs. host disease

Researchers at Moffitt Cancer Center have conducted a clinical trial aimed at preventing graft vs. host disease (GVHD) in patients who have received hematopoietic (blood) cell transplants (HCT). The study, comparing the drug tacrolimus (TAC) in combination with either methotrexate (MTX ) or sirolimus (SIR), found that the sirolimus/tacrolimus (SIR/TAC) combination was more effective in preventing grades II-IV acute GVHD and moderate-severe chronic GVHD after allogeneic blood cell transplantation.

Immediate rewards for good scores can boost student performance

Test performance can improve dramatically if students are offered rewards just before they are given standardized tests and if they receive the incentive immediately afterward, new research at the University of Chicago shows.

Educators have long debated the value of financial and other rewards as incentives, but a series of experiments in Chicago-area schools showed that with the right kind of rewards, students achievement improved by as much as six months beyond what would be expected.

The perception of corruption in Spain is above the European average

According to a study by the Rey Juan Carlos University, data on objective corruption in Spain are higher in politics than in administrative-official institutions. However, the perception of Spaniards is a lot higher.

Researchers at the Rey Juan Carlos University (URJC) have analysed how corruption is perceived in Spain. They believe that the "echo phenomenon" is fundamental when trying to understand the origin of corruption because it creates social attitudes which lead to the unfulfillment of civic duties.

Study examines federal government payments to separate managed care programs for same patients

CHICAGO – An analysis that included 1.2 million veterans enrolled in the Veterans Affairs health care system and Medicare Advantage plan finds that the federal government spends a substantial and increasing amount of potentially duplicative funds in these separate managed care programs for the care of same individuals, according to a study appearing in JAMA. This study is being published early online to coincide with its presentation at the Annual Research Meeting of AcademyHealth.

EVINCI results could lead to 75 percent reduction of invasive procedures for patients with suspected CAD

Madrid, 26 June 2012: Preliminary findings from the EVINCI study show that the prevalence of "significant" coronary artery disease in patients with chest pain symptoms is lower than expected in Europe. In as much as 75% of this population an accurate non-invasive screening could avoid unnecessary and costly invasive procedures. The three year multicentre European trial will define the most cost effective strategy for diagnosing patients with suspected coronary artery disease.

Computer program aids blood-sugar control among critically ill

A computer-software program more effectively controlled blood-sugar levels among critically ill patients than nurse-directed care did, according to the first large clinical trial of its kind. The results will be presented at The Endocrine Society's 94th Annual Meeting in Houston.

Elderly diabetics have fewer bouts of hypoglycemia at night with new insulin

A new variety of long-lasting insulin, called insulin degludec, lowers the risk of nighttime low blood sugar in elderly diabetic adults compared with insulin glargine, a systematic review of diabetes studies has found. The meta-analysis of phase 3 clinical trials will be presented Monday at The Endocrine Society's 94th Annual Meeting in Houston.

Treating vitamin D deficiency may improve depression

Women with moderate to severe depression had substantial improvement in their symptoms of depression after they received treatment for their vitamin D deficiency, a new study finds. The case report series will be presented Saturday at The Endocrine Society's 94th Annual Meeting in Houston.

Because the women did not change their antidepressant medications or other environmental factors that relate to depression, the authors concluded that correction of the patients' underlying shortage of vitamin D might be responsible for the beneficial effect on depression.

The skinny on what makes us fat

Obesity is a disorder in which fat cells grow larger and accumulate. Certain proteins, called WNT family proteins, function to prevent fat cell formation. However, the activity of WNT proteins can be inhibited by secreted frizzled-related proteins (SFRPs), thus leading to fat cell generation. One of these SFRPs, SFRP5, is highly expressed during fat cell generation and increases during obesity. Dr.
