The uproar that began last year when the U.S. Preventive Services Task Force stated that doctors should no longer offer regular prostate-cancer tests to healthy men continued this week when the task force released their final report.

Vigorous physical activity reduced psoriasis in women
A study of U.S. women suggests that vigorous physical activity may be associated with a reduced risk of psoriasis. Psoriasis is an immunologic disorder characterized by systemic inflammation and scaling of the skin.

Sleep apnea treatment reduces hypertension and heart disease risk
Two studies that included adults with obstructive sleep apnea examined the effectiveness of reducing the risk of cardiovascular outcomes, including high blood pressure, by treatment with continuous positive airway pressure (CPAP).

Poor quality or fake malaria drugs pose threat
Poor quality antimalarial drugs lead to drug resistance and inadequate treatment that pose an urgent threat to vulnerable populations. Emergence of malaria strains that are resistant to artemisinin drugs on the Thailand-Cambodia border make it imperative to improve the drug supply, stressed the researchers.

Moderate weight loss reduces breast cancer risk
Even a moderate amount of weight loss can significantly reduce levels of circulating estrogens that are associated with an increased risk of breast cancer, revealed by researchers at Fred Hutchinson Cancer Research Center.

Why do male avoid veggies
Why are men generally more reluctant to try vegetarian products? According to a new study in the Journal of Consumer Research, consumers are influenced by a strong association of meat with masculinity.

Z-pack antibiotic azithromycin carries heart risk
Vanderbilt researchers have discovered a rare, but important risk posed by the antibiotic azithromycin, commonly called a "Z-pack." The study found a 2.5-fold higher risk of death from cardiovascular death in the first five days of taking azithromycin when compared with another common antibiotic or no antibiotics at all.

Acupuncture improved dyspnea in patients with COPD
Acupuncture appears to be associated with improvement of dyspnea (labored breathing) on exertion, in patients with chronic obstructive pulmonary disease (COPD) revealed by researchers in a new study. 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.

Stroke risk greater for older women with atrial fibrillation
In a study that examined use of the anticoagulant medication warfarin and risk of stroke following a diagnosis of atrial fibrillation in older patients, women, especially those 75 years or older, had a higher risk of stroke than men, regardless of their risk profile and use of warfarin, suggesting that current anticoagulant therapy to prevent stroke might not be sufficient for older women.

New experimental drug reduces autism like behaviors
National Institutes of Health researchers have reversed behaviors in mice resembling two of the three core symptoms of autism spectrum disorders (ASD). An experimental compound, called GRN-529, increased social interactions and lessened repetitive self-grooming behavior in a strain of mice that normally display such autism-like behaviors, the researchers say.

Chronic migraine and daily headaches patients get little benefit from botox injections
Although botulinum toxin A ("Botox") injections are U.S. Food and Drug Administration approved for preventive treatment for chronic migraines, a review and analysis of previous studies finds a small to modest benefit for patients with chronic migraine headaches and chronic daily headaches, although botox injections were not associated with greater benefit than placebo for preventing episodic migraine or chronic tension-type headaches.

One kidney transplanted 2 times in 2 weeks
For the first time, a kidney that had been donated to a patient in need was removed and implanted into a new patient, the third individual to have the organ, after it failed in the first transplant recipient.

Violence during childhood may impact kids' DNA
Children who have experienced violence might really be older than their years. The DNA of 10-year-olds who experienced violence in their young lives has been found to show wear and tear normally associated with aging, a Duke University study has found.

Brain cancer vaccine prepared from brain tumor proves effective
A new brain cancer vaccine tailored to individual patients by using material from their own tumors has proven effective in a multicenter phase 2 clinical trial at extending their lives by several months or longer. The patients suffered from recurrent glioblastoma multiforme-which kills thousands of Americans every year.

Heart failure patients may get benefit from testosterone supplements
Testosterone supplements helped heart failure patients breathe better and exercise more. This new research analyzed four randomized clinical trials of patients with moderate to severe chronic heart failure. Patients were given commercial testosterone supplements by injection, patch or gel.

Bevacizumab with chemotherapy provides no survival benefit for lung cancer patients
Adding the drug bevacizumab (Avastin) to the standard chemotherapy regimen for non-small cell lung cancer (NSCLC) – an approach approved by the FDA in 2006 – did not lead to significantly increase survival rates for patients over the age of 65 enrolled in Medicare.

Bariatric surgery better for obese with type 2 diabetes
A study comparing a bariatric surgical procedure with conventional medical treatment in morbidly obese patients with type 2 diabetes mellitus suggests that surgery was associated with remission or improvement in diabetes-related outcomes.

IMRT Radiation optimal for localized prostate cancer
A treatment for localized prostate cancer known as Intensity Modulated Radiation Therapy (IMRT) is better than conventional conformal radiation therapy (CRT) for reducing certain side effects and preventing cancer recurrence.

Depression - now blood test can diagnose depression in teens
A breakthrough approach that allows an objective diagnosis of major depression in teens by measuring a specific set of genetic markers found in a patient's blood. The current method of diagnosing depression is subjective. It relies on the patient's ability to recount his symptoms and the physician's ability and training to interpret them.

Chin augmentation - fastest growing plastic surgery in US
Do you have double chin? Chin augmentation is the fastest growing plastic surgery trend among all major demographics -- a phenomenon which appears, in part, to be sparked by increased usage of video chat technology, an aging baby boomer population and a desire for success in the workplace.

Less sleep means higher risk of diabetes and obesity
A new study reinforces the finding that too little sleep or sleep patterns that are inconsistent with our body's "internal biological clock" may lead to increased risk of diabetes and obesity. This finding has been seen in short-term lab studies and when observing human subjects via epidemiological studies.

Whole genome breast cancer study launched by Mayo Clinic USA
The Breast Cancer Genome Guided Therapy Study (BEAUTY Project) will help physicians tailor chemotherapy to breast cancer patients based on their individual genomes and the genomes of their tumors.

Genetic changes in 3 genes linked to autism spectrum disorders
Mutations in three new genes have been linked to autism, according to new studies including one with investigators at Mount Sinai School of Medicine. All three studies include lead investigators of the Autism Sequencing Consortium (ASC).

Two genes TPH1 and TPH2 more likely to develop PTSD symptoms
Why do some persons succumb to post-traumatic stress disorder (PTSD) while others who suffered the same ordeal do not? UCLA scientists have linked two genes involved in serotonin production to a higher risk of developing PTSD.

Increasing height and body mass index linked to ovarian cancer risk
Increasing height and, among women who have never taken menopausal hormone therapy, increased body mass index are risk factors for developing ovarian cancer in women, revealed by researchers.

First stress and then inflammation is the culprit
Can removing stress from my environment make me healthy & happier? Yes, it is proven by a recent research that shows how stress influences disease and our health.
