In psychology, there are competing speculations about bias. Some claim that if people do poorly on a test, it is because they are already perceived as being poor at it; a small white guy may do poorly at basketball, a woman may do poorly on a math test, because they believe their reputations precede them and that performance pressure ironically causes the under-performance.

Philadelphia, PA, April 16, 2013 – Atherosclerosis – sometimes called "hardening of the arteries" – is a leading cause of death and morbidity in Western countries. A cell-permeable peptide containing the NF-ĸB nuclear localization sequence (NLS) shows promise as a potential agent in controlling the development of atherosclerotic disease. This study is published in the May 2013 issue of The American Journal of Pathology.
A new study concludes that approximately half of the prescriptions of Tamiflu during the 2009-10 influenza pandemic went unused in England. The unused medication represents approximately 600,000 courses of Tamiflu at a cost of around £7.8 million to the UK taxpayer. The novel scientific method used in the study could help measure and improve the effectiveness of future pandemic flu strategies.
A new report prepared in collaboration with the International Osteoporosis Foundation (IOF) and the European Federation of Pharmaceutical Industry Associations, is the first to describe in detail the epidemiology, burden, and treatment of osteoporosis in all 27 member states of the European Union (EU27).
Combining CT imaging findings with baseline serum lactate dehydrogenase levels is showing promise as a way to predict survival in patients with metastatic melanoma being treated with anti-angiogenic therapy.
A partnership involving the public and private sector successfully addressed the mental health needs of people in the post-conflict regions of northern Uganda and could be used as a model in other post-conflict settings, according to a Health In Action article by Ugandan and US researchers published in this week's PLOS Medicine as part of an ongoing series on Global Mental Health Practice.
A common test that records the heart's electrical activity could predict potentially serious cardiovascular illness, according to a UC San Francisco-led study.
A cardiac condition called left anterior fascicular block (LAFB), in which scarring occurs in a section of the left ventricle, may not be as benign as currently thought and could increase the likelihood of heart failure, sudden cardiac death or atrial fibrillation.
Boston, MA -- Privately insured surgical patients who had a complication provided hospitals with a 330% higher profit margin than those without a complication, according to new research from Ariadne Labs, a joint center for health system innovation at Brigham and Women's Hospital (BWH) and Harvard School of Public Health (HSPH), Boston Consulting Group, Texas Health Resources, and Massachusetts Eye and Ear Infirmary. Medicare patients with a complication produced a 190% higher margin.
Findings of an analysis that included nearly 35,000 surgical discharges from a 12-hospital system suggest that the occurrence of postsurgical complications was associated with a higher per-encounter hospital contribution margin for patients covered by Medicare and private insurance but a lower one for patients covered by Medicaid and who self-paid, according to a study in the April 17 issue of JAMA.
Treatment that consisted of shock wave (procedure using high-dose ultrasound)-mediated preconditioning of the target heart tissue prior to administration of bone marrow-derived mononuclear cells was associated with significant, albeit modest improvement in left ventricular ejection fraction (a measure of how well the left ventricle of the heart pumps with each contraction) after 4 months in patients with chronic postinfarction heart failure, according to a study in the April 17 issue of JAMA.
Philadelphia, Pa. (April 16, 2013) - Lower mortality and other improved patient outcomes achieved at designated "Magnet hospitals" are explained partly—but not completely—by better nurse staffing, education, and work environment, reports a study in the May issue of Medical Care.
CHICAGO --- A study published today in the European Heart Journal found no evidence that digoxin increases mortality in patients with atrial fibrillation (AF), the opposite of results just published by another group in the same journal analyzing the same data.
Researchers from North Carolina State University and the University of North Carolina at Chapel Hill (UNC) have developed a new tool to help surgeons use X-rays to track devices used in "minimally invasive" surgical procedures while also limiting the patient's exposure to radiation from the X-rays.
The climate governs the seasonal activity of vegetation; humankind influences it. In the humid mid-latitudes, temperature is the largest influencing factor for plant growth. In predominantly dry areas, however, it is the availability of water and in the high latitudes incident solar radiation. Without a doubt, humankind also has a modifying impact on the ecosystem. Satellites have been recording how the vegetation on the Earth's surface is changing since the 1980s.
PHILADELPHIA - A study led by researchers at the Perelman School of Medicine at the University of Pennsylvania and Boston University School of Medicine has found that nearly one quarter of patients may return to the emergency department within 30 days of being discharged from a hospitalization. None of these emergency room visits that do not lead to subsequent admission are included in calculating hospital readmission rates, which are a key focus of health care cost containment and quality improvement efforts. The findings are published in Annals of Emergency Medicine.
