Official assessments of a doctor's professionalism should be considered carefully before being accepted due to the tendency for some doctors to receive lower scores than others, and the tendency of some groups of patient or colleague assessors to provide lower scores, claims new research published online in the British Medical Journal.

An international team of scientists led by Monash University researchers has uncovered how a common hospital bacterium becomes a deadly superbug that kills increasing numbers of hospital patients worldwide and accounts for an estimated $3.2 billion each year in health care costs in the US alone. Their findings appear October 13th in the Open Access journal PLoS Pathogens.

Interactive video games, already known to improve motor function in recovering stroke patients, appear to safely enhance physical therapy for patients in intensive care units (ICU), new research from Johns Hopkins suggests.

In a report published online in the Journal of Critical Care, researchers studied the safety and feasibility of using video games to complement regular physical therapy in the ICU.

Patients suffering from chronic obstructive pulmonary disease (COPD) are at a higher risk of death if they are underweight.

A new study, which will be presented September 26, 2011 at the European Respiratory Society's Annual Congress in Amsterdam, assessed the link between death rates and the weight of COPD patients. The research also assessed the link with other co-existing diseases, such as heart disease.

Scientists at la Universidad Carlos III de Madrid (UC3M -- Carlos III University in Madrid) who participate in the LOBIN consortium have developed an 'intelligent' T-shirt that monitors the human body (temperature, heart rate, etc.) and locates patients within the hospital, as if it were a GPS system that works in closed spaces. It can even determine if the subject is seated, lying down, walking or running.

Time is of the essence when it comes to stroke treatment. But a new image guided technique could help shift the criterion from one that is determined by how long after the start of symptoms a patient receives medical care, suggests a small US study published online in the Journal of NeuroInterventional Surgery.

Cognitive impairment, even when detected at an early, mild stage, is a significant predictor of decreased life expectancy.

According to a new, long-term study from Regenstrief Institute and Indiana University researchers, cognitive impairment, especially at the moderate to severe stages has an impact on life expectancy similar to chronic conditions such as diabetes or chronic heart failure. Their findings, "Cognitive Impairment: An Independent Predictor of Excess Mortality. A Cohort Study" appears in the Sept. 6, 2011 issue of Annals of Internal Medicine.

More than 60 percent of hospital nurses' and doctors' uniforms tested positive for potentially dangerous bacteria, according to a study published in the September issue of the American Journal of Infection Control, the official publication of APIC -- the Association for Professionals in Infection Control and Epidemiology.

Use of natural language processing, such as in the form of free-text searches of electronic medical records (EMRs) of clinical and progress notes of patients performed better at identifying postoperative surgical complications than the commonly used administrative data codes in EMRs, according to a study in the August 24/31 issue of JAMA.

Antibiotics can help ward off serious bacterial infections in kidney disease patients who use tubes called catheters for their dialysis treatments. But if antibiotics are used too often, "super bugs" may crop up that are resistant to the drugs.
