Breath Test To Identify Stress
Date: Mar-01-2013The perennial stress-buster - a deep breath - could become stress-detector, claims a team of researchers from the UK. According to a new pilot study, published, in IOP Publishing's Journal of Breath Research, there are six markers in the breath that could be candidates for use as indicators of stress...
Hope For First Effective Treatment For Vitiligo
Date: Mar-01-2013Loyola University Chicago Stritch School of Medicine researchers have developed a genetically modified protein that dramatically reverses the skin disorder vitiligo in mice, and has similar effects on immune responses in human skin tissue samples. The modified protein is potentially the first effective treatment for vitiligo, which causes unsightly white patches on the face, hands and other parts of the body. Loyola University Chicago has submitted a patent application for the protein, and researchers are seeking regulatory approval and funding for a clinical trial in humans. I...
Diabetes Not Found To Impact Infection Risk, Surgical Outcomes
Date: Mar-01-2013Patients with diabetes were no more likely to suffer infection, deep vein thrombosis (a deep vein blood clot) or other complications following total knee replacement (TKR) than patients without diabetes, according to new research published online, in advance of its publication in the March 2013 Journal of Bone and Joint Surgery (JBJS). The study authors sought to determine whether or not blood sugar level (glycemic control) influenced outcome in TKR. Fifty-two percent of people with diabetes have arthritis...
Molecule Discovered That Dampens Pathways That Ignite Inflammation, Clears Away Cells That Fuel Inflammation In Asthma
Date: Mar-01-2013Scientists from Brigham and Women's Hospital are on the brink of the next treatment advancement that may spell relief for the nearly nineteen million adults and seven million children in the United States suffering from asthma. The scientists discovered two new drug targets in the inflammatory response pathway responsible for asthma attacks. The study was published in Science Translational Medicine. Researchers studied the lungs and blood of 22 people with mild and severe asthma...
A Pirate Phage Commandeers The Immune System Of Bacteria
Date: Mar-01-2013A study published in the journal Nature reports that a viral predator of the cholera bacteria has stolen the functional immune system of bacteria and is using it against its bacterial host. The study provides the first evidence that this type of virus, the bacteriophage ("phage" for short), can acquire a wholly functional and adaptive immune system. The phage used the stolen immune system to disable - and thus overcome - the cholera bacteria's defense system against phages...
The Dietary Causes Of Heart Disease
Date: Mar-01-2013A 98-year-old researcher argues that, contrary to decades of clinical assumptions and advice to patients, dietary cholesterol is good for your heart - unless that cholesterol is unnaturally oxidized (by frying foods in reused oil, eating lots of polyunsaturated fats, or smoking). The researcher, Fred Kummerow, an emeritus professor of comparative biosciences at the University of Illinois, has spent more than six decades studying the dietary factors that contribute to heart disease...
Worrying Upward Trend In Obesity Rates In Canadian Adult Population
Date: Mar-01-2013Obesity rates across Canada are reaching alarming levels and continue to climb, according to a new University of British Columbia study. Published in the Canadian Journal of Public Health, the study provides the first comprehensive look at adult obesity rates across Canada since 1998, complete with "obesity maps." "Being obese or overweight significantly increases the risk of chronic illnesses, such as heart disease, diabetes, and some cancers," says study lead author, Prof. Carolyn Gotay in UBC's School of Population and Public Health...
Study Examines Huge Variation In Patient Bills For Top 10 Visits To The Emergency Room
Date: Mar-01-2013It's a basic, reasonable question: How much will this cost me? For patients in the emergency room, the answer all too often is a mystery. Emergency departments play a critical role in health care, yet consumers typically know little about how medical charges are determined and often underestimate their financial responsibility -- then are shocked when the hospital bill arrives. A new study led by UC San Francisco highlights the problem by identifying giant price swings in patient charges for the 10 most common outpatient conditions in emergency rooms across the country...
Individuals At High Risk Of Developing Type 2 Diabetes Should Address The Balance Between Sedentary Behaviour And Physical Activity
Date: Mar-01-2013New research led at the University of Leicester reveals that individuals at high risk of developing type 2 diabetes would benefit from being told to sit less and move around more often - rather than simply exercising regularly. The experts suggest that reducing sitting time by 90 minutes in total per day could lead to important health benefits. Currently, at risk patients are advised to engage in moderate-to-vigorous physical activity (MVPA) for at least 150 mins per week...
Study Offers Hope In Fight Against Common Skin Cancer
Date: Mar-01-2013Hailed as a major step forward in the effort to develop targeted cancer therapies, a recently approved drug for the most common type of skin cancer has been a mixed blessing for patients. Although the initial response is usually dramatic, the tumors often recur as the cancer becomes resistant to treatment. Now researchers at the Stanford University School of Medicine have identified a second way to block the activity of the signaling cascade, called the Hedgehog pathway, that is abnormally active in these cancers...
