New study shows artery-opening procedure still widely used in spite of changed guidelines

Despite changes in standard treatment practice guidelines issued by the American College of Cardiology, American Heart Association and the European Society of Cardiology several years ago, there has been no meaningful change in the nation's practice of opening completely blocked coronary arteries with balloons and stents in the days after a heart attack, according to a new study published in the July 11, 2011, issue of Archives of Internal Medicine. The new study concludes that cardiologists in the United States are still performing this procedure late after a heart attack.

Pitt team finds way to classify post-cardiac arrest patients to better predict outcomes

PITTSBURGH, July 11 – A new method for scoring the severity of illness for patients after cardiac arrest may help to predict their outcomes, according to researchers at the University of Pittsburgh School of Medicine. Most importantly, their findings, published in the early online version of Resuscitation, also show that none of the severity categories rules out the potential for a patient's recovery.

New study may lead to quicker diagnosis, improved treatment for fatal lung disease

SALT LAKE CITY – One-fifth of all patients with pulmonary arterial hypertension suffer with the fatal disease for more than two years before being correctly diagnosed and properly treated, according to a new national study led by researchers at Intermountain Medical Center in Salt Lake City.

'Healthy' habits linked to childhood obesity in China

Teenaged boys from well-off Chinese families who say they are physically active and eat plenty of vegetables but few sweets are more likely to be overweight, according to a study led by researchers at the Keck School of Medicine of the University of Southern California (USC).

No difference in brand name and generic drugs regarding thyroid dysfunction

There is no difference between brand-name and generic drug formulations of amiodarone — taken to control arrhythmia – in the incidence of thyroid dysfunction, according to a study in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/site/embargo/cmaj101800.pdf.

Writing DNR orders takes longer, death more likely when surrogate decision-maker involved

INDIANAPOLIS – Indiana University and Regenstrief Institute researchers report that it takes significantly longer for orders to forgo resuscitation in the event of cardiac arrest to be written for patients who had that decision made for them by a surrogate decision-maker compared to patients who made their own decisions, even though patients with a surrogate were sicker and the resuscitation issue might arise sooner.

Parkinson's disease patients may benefit from virtual-reality-based therapies

Philadelphia, PA, July 11, 2011 – In people with Parkinson's Disease (PD), the inability to make quick movements limits basic functioning in daily life. Movement can be improved by various cueing techniques, such as providing visual or auditory stimuli when movements are started. In a study scheduled for publication in the August issue of the Archives of Physical Medicine and Rehabilitation, researchers report that virtual reality (VR) and physical reality exercises can be used to provide effective stimuli to increase movement speeds in PD patients.

'Resilience' of US metros measured by online index developed by UB researchers

BUFFALO, N.Y. -- Which U.S. metro region is most likely to come out of the next recession, natural disaster or other regional "shock" relatively unscathed? Rochester, Minn. A little more battered might be College Station-Bryan, Texas.

These two regions are ranked first and last, respectively, by a new online tool measuring more than 360 U.S. metros for their "regional resilience," or capacity to weather acute and chronic stresses ranging from gradual economic decline to rapid population gains to earthquakes and floods.

Carsey Institute: Lack of sick leave creates tough choices for rural workers

DURHAM, N.H. – Rural workers have less access to sick leave, forcing them to choose between caring for themselves or family members, and losing pay or perhaps even their jobs when faced with an illness, according to new research from the Carsey Institute at the University of New Hampshire.

Athletes may have different reasons for marijuana use

College athletes tend to be less likely than their non-athlete peers to smoke marijuana. But when they do, they may have some different reasons for it, according to a study in the July issue of the Journal of Studies on Alcohol and Drugs.

Past studies have shown that athletes generally smoke marijuana less often than other college students do.

"But there is still a pretty large number who choose to use it," said Jennifer F. Buckman, Ph.D., of the Center of Alcohol Studies at Rutgers University in Piscataway, New Jersey.

The perfect connection between guitar and computer

Rapidly, but expressively and with amazing ease, the guitarist's fingers move over the strings on the neck of the instrument. His fingertips move up and down and a vibrato resonates. From the guitar a cable leads to a laptop, which records the virtuoso performance in minute detail. The computer registers each vibrato, each bend precisely and almost instantaneously. Afterwards the guitarist can play back the digital recording and process it on a computer.

Vitamin D insufficiency prevalent among psoriatic arthritis suffers

New research reports a high prevalence of vitamin D insufficiency and deficiency among patients with psoriatic arthritis. Seasonal variation in vitamin D levels was not observed in patients in southern or northern locations. The findings published today in Arthritis Care & Research, a journal of the American College of Rheumatology (ACR), also show no association between disease activity and vitamin D level.

Obese patients less likely to develop and die from respiratory distress syndromes after surgery

Researchers have discovered that obese adults undergoing surgery are less frequently developing respiratory insufficiency (RI) and adult respiratory distress syndrome (ARDS), and that when they do, they are less likely to have fatal outcomes. The researchers say they have several theories of how obesity protects patients from mortality associated with RI/ARDS, and pinpointing the protective mechanism could help them develop interventions to help non-obese patients avoid adverse outcomes.

Loss of motion after knee surgery may increase osteoarthritis risk, research suggests

SAN DIEGO, CA – The onset of osteoarthritis may be related to a loss of knee motion after reconstructive ACL surgery, as noted in new research presented at the American Orthopaedic Society for Sports Medicine's Annual Meeting in San Diego, California, July 7-10, 2011. Patients who showed motion limitations after surgery were more likely to develop arthritic changes in the knee.

Clyde fish stock at 80-year high -- but most are too small to be landed

Stocks of seabed-living fish in the Firth of Clyde have reached their highest level since 1927 – according to research by academics at the University of Strathclyde.

However, the report, produced by Professor Mike Heath and Dr Douglas Speirs of the University's Marine Population Modelling Group, shows that while fish are actually more abundant than ever, the majority are too small to be landed.
