Study examines exercise testing in asymptomatic patients after coronary revascularization

2012-05-15
(Press-News.org) Asymptomatic patients who undergo treadmill exercise echocardiography (ExE) after coronary revascularization may be identified as being at high risk but those patients do not appear to have more favorable outcomes with repeated revascularization, according to a report published Online First by Archives of Internal Medicine, a JAMA Network publication. The article is part of the journal's Less is More series.

Cardiac events and recurrent ischemia (a temporary shortage of oxygen caused by impaired blood flow; identified in the study as new or worsening cardiac wall motion abnormality shown on the echocardiogram) are common after revascularization procedures, both percutaneous coronary intervention (PCI) and coronary bypass graft surgery (CABG).

Guidelines of the American College of Cardiology/American Heart Association recommend evaluation with stress imaging tests, including ExE, in symptomatic patients after revascularization, but evaluating asymptomatic patients "is more controversial," the authors note in the study background.

"Testing is considered inappropriate early after PCI ( END

Acupuncture appears linked with improvement in patients with chronic obstructive pulmonary disease

2012-05-15
According to a small clinical trial reported by investigators from Japan, acupuncture appears to be associated with improvement of dyspnea (labored breathing) on exertion, in patients with chronic obstructive pulmonary disease (COPD), according to a study published Online First by Archives of Internal Medicine, a JAMA Network publication. The management of dyspnea is an important target in the treatment of COPD, a common respiratory disease characterized by irreversible airflow limitation. COPD is predicted to be the third leading cause of death worldwide by 2020, according ...

Study examines retinal vessel diameter and CVD risk in African Americans with type 1 diabetes

2012-05-15
Among African Americans with type 1 diabetes mellitus, narrower central retinal arteriolar equivalent (average diameter of the small arteries in the retina) is associated with an increased risk of six-year incidence of any cardiovascular disease and lower extremity arterial disease, according to a report in the May issue of Archives of Ophthalmology, a JAMA Network publication. "Retinal arteriolar narrowing has long been described as one of the characteristic changes associated with hypertension and cardiovascular disease (CVD)," the authors write as background information ...

Bio-hybrid device acts as 'thermostat' to control systemic inflammation in sepsis

2012-05-15
PITTSBURGH, May 14 - A small, external bioreactor holding human cells pumped out an anti-inflammatory protein to prevent organ damage and other complications in a rat with acute inflammation caused by bacterial products in a model of sepsis, according to a report from researchers at the University of Pittsburgh School of Medicine and the McGowan Institute for Regenerative Medicine. The findings were published today in the inaugural issue of Disruptive Science and Technology. Inflammation is a necessary biological response that brings cells and proteins to the site of ...

Preventing depression requires proactive interventions by health-care system

2012-05-15
Major depressive episodes can be prevented, and to help ensure that they are, the health care system should provide routine access to depression-prevention interventions, just as patients receive standard vaccines, according to a new article co-authored by UCSF researcher Ricardo F. Muñoz, PhD. The article builds on a 2009 Institute of Medicine report on prevention of mental, emotional and behavioral disorders, which provided presented evidence that mental disorders can be prevented. The article, "Major Depression Can Be Prevented," will appear in a special section ...

Researchers say urine dipstick test is accurate predictor of renal failure in sepsis patients

Researchers say urine dipstick test is accurate predictor of renal failure in sepsis patients
2012-05-15
DETROIT – Henry Ford Hospital researchers have found that the presence of excess protein in a common urine test is an effective prognostic marker of acute renal failure in patients with severe sepsis. Researchers analyzed data from 328 sepsis patients with no previous history of protein in the urine and found the urine dipstick test predicted the presence of renal failure in 55 percent of these patients. A urine dipstick test is routinely done as part of a urinalysis to help diagnose urinary tract infections, kidney disease, diabetes and sepsis, the deadly bloodstream ...

Researchers reveal different mechanisms of pain

2012-05-15
Researchers at the University of Leeds have found a previously unknown mechanism through which pain is signalled by nerve cells – a discovery that could explain the current failings in the drug development process for painkillers and which may offer opportunities for a new approach. The team, led by Dr Nikita Gamper of the University's Faculty of Biological Sciences, is investigating the difference between persistent pain, such as toothache, and pain that results from the increased sensitivity of nerves in injured or diseased tissue (for example when we touch inflamed ...

Scientists make groundbreaking discovery of mutation-causing genetic disorder in humans

Scientists make groundbreaking discovery of mutation-causing genetic disorder in humans
2012-05-15
Scientists at A*STAR's Institute of Medical Biology (IMB), in collaboration with doctors and scientists in Jordan, Turkey, Switzerland and USA, have identified the genetic cause of a birth defect known as Hamamy syndrome . Their groundbreaking findings were published on May 13th in the prestigious journal Nature Genetics. The work lends new insights into common ailments such as heart disease, osteoporosis, blood disorders and possibly sterility. Hamamy syndrome is a rare genetic disorder which is marked by abnormal facial features and defects in the heart, bone, blood ...

Urban landscape's power to hurt or heal

2012-05-15
Research shows that street furniture, barriers, parks, public spaces and neighbourhood architecture can stir up powerful emotions in local residents. This should be taken into account in programmes designed to reduce tensions and foster community cohesion. Four cities - Amsterdam, Beirut, Belfast and Berlin were chosen as the location of the research as each has a different social history and underlying tensions. The project was undertaken by Dr Ralf Brand of the University of Manchester and was funded by the Economic and Social Research Council (ESRC). Dr Brand found ...

Researchers from UC3M monitor a chicken's brain

Researchers from UC3M monitor a chickens brain
2012-05-15
This is one of the principle conclusions of a study that has been published in the scientific journal Current Biology. Participants in the study included Evan Balaban (McGill University, Montreal), Manuel Desco (Gregorio Marañón General University Hospital of Madrid and UC3M) and Juan José Vaquero (UC3M). The researchers managed to arouse a chicken embryo by exposing it to a sound that would have meaning after its birth (for example, the sound of a chicken warning others of danger). However, their study has demonstrated that the animal does not have the same reaction when ...

Legislation to ban burqa is liberal overkill, researchers claim

2012-05-15
Banning and criminalising the Muslim face veil tests the very foundations of modern liberal society, warn researchers from Queen Mary, University of London and the University of Sussex. The paper 'Reasons to Ban? The Anti-Burqa Movement in Western Europe' examines the move to legislate against, and to criminalise face-veiling which has swept across the EU recently. The European movement against face-veiling is now widespread, with calls to implement a ban, or a ban being in place, in France, Belgium, Italy, Spain, the Netherlands, Scandinavia, and Germany. This move ...
