First two weeks of football practice the most dangerous for heat-related illness Posted: 29 Aug 2016 11:13 AM PDT Football players are more likely to suffer from heat-related illness during the first two weeks of practice, especially those in the Southeastern U.S.

Use it or lose it: Stopping exercise decreases brain blood flow Posted: 29 Aug 2016 11:04 AM PDT Researchers examined cerebral blood flow in master athletes (ages 50-80 years) before and after a 10-day period during which they stopped all exercise. Using MRI brain imaging techniques, they found a significant decrease in blood flow to several brain regions important for cognitive health, including the hippocampus, after they stopped their exercise routines.

Blinding disease in canines and humans shares causative gene, pathology Posted: 29 Aug 2016 11:04 AM PDT Scientists report that they've directly compared the disease course of a blinding ciliopathy between humans and dogs and found remarkable similarities.

Majority of older adults in jail have distressing health symptoms Posted: 29 Aug 2016 09:31 AM PDT According to the study, of the older inmates, 49 percent said they experience poor or fair health, 20 percent have chronic lung disease, and 54 percent have trouble performing daily activities such as bathing, eating, using the toilet, and walking around the house. The researchers said that these rates are similar to those reported by lower income older adults who are not incarcerated.

Alzheimer's: Nicotinic receptors as a new therapeutic target Posted: 29 Aug 2016 09:31 AM PDT Studies have indicated that nicotine may be beneficial for memory function. Scientists are set out to shed further light on the properties attributed to nicotine by determining the precise structure of the nicotinic receptors in the hippocampus region of the brain. Using mouse models for Alzheimer's disease, they identified the a subunit of the nicotinic receptor as a target that, if blocked, prevents the memory loss associated with Alzheimer's.

Outpatient bloodstream infections costly for pediatric transplant and cancer patients Posted: 29 Aug 2016 09:31 AM PDT Pediatric stem cell transplant and cancer patients often are discharged from the hospital with an external central venous line for medications that parents or other caregivers must clean and flush daily to avoid potentially life-threatening infections. If an outpatient develops a bloodstream infection associated with the central line, median charges to treat it total $37,000 for a six-day hospital stay for young patients whose disease treatments have weakened their immune systems and infection-fighting abilities.

New hope for Zika treatment found in large-scale screen of existing drugs Posted: 29 Aug 2016 09:22 AM PDT Scientists report that a specialized drug screen test using lab-grown human cells has revealed two classes of compounds already in the pharmaceutical arsenal that may work against mosquito-borne Zika virus infections.

Many adults who screen positive for depression don't receive treatment Posted: 29 Aug 2016 09:21 AM PDT A new study suggests gaps exist in the treatment of depression with many individuals who screen positive for the mental health disorder not receiving treatment, according to a new article.

Artificial intelligence expedites breast cancer risk prediction Posted: 29 Aug 2016 09:21 AM PDT Researchers have developed an artificial intelligence (AI) software that reliably interprets mammograms, assisting doctors with a quick and accurate prediction of breast cancer risk. The AI computer software intuitively translates patient charts into diagnostic information at 30 times human speed and with 99 percent accuracy.

Why people with type O blood are more likely to die of cholera Posted: 29 Aug 2016 07:59 AM PDT People with blood type O get sicker from cholera than people of other blood types. Researchers have found that cholera toxin activates a key molecule more strongly in people with blood type O than type A, possibly worsening symptoms.

Peptide mutants may help to identify vulnerability in tumor cells Posted: 29 Aug 2016 07:49 AM PDT Researchers have presented an algorithm to detect mutant proteins based on mass spectrometry data and the results of exome sequencing. Using this new approach, the scientists have discovered unique genome variants, some of which are linked to cancer development. Studying mutant peptides will help to detect weaknesses in tumor cells in search for more effective drug treatments.

Patients with moderate to severe TBI twice as likely to die from an unintentional injury Posted: 29 Aug 2016 07:49 AM PDT Research examining adults with moderate to severe TBI who participated in rehabilitation showed that they were twice as likely to die from an unintentional injury that occurred following their TBI. This was in comparison to individuals in rehabilitation of similar age, sex, and race but without TBI. People who have had a moderate to severe TBI may experience changes in cognition and balance, which may put them at greater risk of subsequent unintentional injuries.

Telemedicine could improve eye exam access for people with diabetes Posted: 29 Aug 2016 06:56 AM PDT People with diabetes need vision screening every year to prevent blindness. What if the eye doctor came to them?

Doctors prescribe diabetes treatment medications 15 times more than obesity drugs Posted: 29 Aug 2016 06:56 AM PDT Obesity is a well-established major risk factor for developing diabetes, with almost 90% of people living with type 2 diabetes having obesity or overweight. Even with the close tie between obesity and type 2 diabetes, new research shows that healthcare clinicians prescribe 15 times more antidiabetes medications than those for obesity. Although six antiobesity medications are now approved by the Food and Drug Administration (FDA) for treating obesity when combined with a reduced-calorie diet and increased physical activity, this research points out that only 2% of the eligible 46% of the U.S. adult population is receiving these medications.

Melanoma: mechanisms of BRAF-inhibitor resistance deciphered Posted: 29 Aug 2016 06:43 AM PDT BRAF mutation occurs in between 40% and 50% of metastasising melanomas (skin cancers), boosting tumour growth. Patients with metastasising melanomas and who display BRAF mutation can be treated with an inhibitor that acts specifically against BRAF mutation (BRAF inhibitor in combination with MEK inhibitor). Initially the treatment is extremely effective but, after a maximum of 11 months, the patient becomes resistant to it. Researchers have now identified some of the mechanisms that might cause this resistance.

'Multiplicative' Benefit of Cholesterol and Blood Pressure-Lowering on Cardiovascular Risk Posted: 29 Aug 2016 06:43 AM PDT Long-term exposure to the combination of even modestly lower LDL cholesterol (LDL-C) and systolic blood pressure (SBP) has the potential to "dramatically reduce" a person's lifetime risk of cardiovascular disease, according to new findings.

A few extra pounds can't hurt you -- or can they? Posted: 29 Aug 2016 06:40 AM PDT Being overweight increases the chances of premature death . This statement is backed by a four-continent effort involving 239 studies and data from 10.6 million people. The study -- one of the largest to date -- runs counter to the results of a 2013 paper in the Journal of the American Medical Association, which found that being overweight actually adds to one's lifespan.

Mediterranean diet associated with lower risk of early death in cardiovascular disease patients Posted: 29 Aug 2016 06:40 AM PDT The Mediterranean diet is associated with a reduced risk of death in patients with a history of cardiovascular disease, according to results from the observational study.

Defibrillators could save many more lives if associated with basic life support education Posted: 29 Aug 2016 06:40 AM PDT Automatic external defibrillators fail to save lives when the public does not have basic life support education, according to new research. The study found that public access defibrillation programs are unevenly deployed across France, with an obvious impact on out-of-hospital cardiac arrest survival rate.

Traffic accidents increased by 50 percent in patients with implantable cardioverter defibrillator Posted: 29 Aug 2016 06:40 AM PDT The risk of traffic accidents is increased by 50 percent in patients with an implantable cardioverter defibrillator compared to age and gender matched controls, according to a Danish nationwide registry study.

iPads as effective as sedatives for children before operations Posted: 29 Aug 2016 06:40 AM PDT New research shows that allowing children to use iPads to distract them before surgery requiring general anesthesia is as effective at lowering their anxiety as conventional sedatives.

Asthma care costs UK at least £1.1 billion each year, study shows Posted: 29 Aug 2016 06:40 AM PDT Asthma costs the UK health service at least 1.1 billion pounds each year, research has estimated.

Parkinson's study could pave way for early detection test Posted: 29 Aug 2016 06:40 AM PDT A test that can detect Parkinson's disease in the early stages of the illness has moved a step closer.
