Honesty may not be the best policy for hospital safety grades, study suggests
When a child brings home a report card from school, part of their grade comes from how often they made it to class or turned in homework. But the larger part comes from how they did on tests, in class and on take-home assignments. In other words, how much they've learned, or how hard they're trying.

The life-saving treatment that's being thrown in the trash
A few hours before beginning chemotherapy, a man named Chris faces his cellphone camera with a mischievous smile and describes a perfectly absurd milestone at 1.37pm on a Wednesday. "There is no more beautiful moment in a man's life…" he says with puckish glee. Because how can you not laugh when you've been invited to bank your sperm in advance of being "Godzilla-ed" with chemotherapy and radiation, all just four days after being diagnosed with acute myeloid leukaemia at the age of 43 and given a 5 to 15 per cent chance of survival?

Health problems may increase as young people infected with HIV at birth get older
A new study has found that U.S. youth infected with HIV around the time of their birth are at higher risk throughout their adolescence and young adulthood for experiencing serious health problems, poor control of the HIV virus or death. The report, led by researchers at Massachusetts General Hospital (MGH), has been published online in JAMA Pediatrics.

Team develops 'calculator' to predict risk of early hospital readmission
Patients who are discharged after a hospital stay will want to stay away from the hospital for as long as possible. However, in Singapore, approximately 15 per cent of patients who have been discharged from hospitals will succumb to a readmission within 30 days, while globally, readmission rates within 30 days can be as high as 20 per cent.

Seven months after Rio Olympics, Zika continues to plague babies in urban slums
Many international travelers to the 2016 Summer Olympics in Rio De Janeiro, Brazil, openly considered skipping the games to avoid the threat of Zika. Despite the fears, not a single case of Zika or its major neurological complication, microcephaly, was reported by foreign visitors. The near-paranoia—and the diversion of scarce resources to protect a low-risk population—could have been avoided by heeding the lessons of previous epidemics, argues a new study from public health researchers at UC Berkeley.

Encouraging results for patients with aggressive brain cancer
Being diagnosed with a malignant brain tumor is devastating news for patients and their loved ones. Whereas some types of tumor respond well to treatment, others such as glioblastomas - the most common and aggressive brain tumors - are known to recur and progress within short times from the diagnosis. Patients diagnosed with this type of cancer, and who undergo current standard treatment, have a median survival of 16 months.

Team finds another immune system link science said didn't exist
The University of Virginia School of Medicine has again shown that a part of the body thought to be disconnected from the immune system actually interacts with it, and that discovery helps explain cases of male infertility, certain autoimmune diseases and even the failure of cancer vaccines.

Vaccine, improved treatment are keys to control of a surging HIV pandemic
Development and widespread use of a vaccine that's even partially effective against HIV, along with more progress toward diagnosis and treatment, offer the best hopes for turning the corner on a global pandemic that's still spiraling out of control, researchers reported today.

A simple fix to avoid some unnecessary coronary stents
Physician researchers at Thomas Jefferson University suspect that some cases of coronary artery spasm go unrecognized and are incorrectly treated with stents. The good news - there could be a simple fix to eliminate these unnecessary stenting procedures. The team published a case series in Catheterization and Cardiovascular Interventions describing six patients who were scheduled for angioplasty and stenting for the diagnosis of coronary artery disease (five of whom had a cardiac catheterization days prior). However, when the cardiologists gave nitroglycerin prior to placing the stent, the blockages resolved, indicating the true diagnosis of coronary artery spasm. Angioplasty was deferred and all patients were successfully treated with medication.

Fewer U.S. kids overdosing on opioids
(HealthDay)—The number of U.S. kids who overdose on prescription painkillers each year may be declining—but the incidents remain a major public health problem, new research says.

DNA labels predict mortality
Various chemical modifications in the genome determine whether genes are read or deactivated. Methyl labels in the DNA play a key role in this "epigenetic" regulation of gene activity. Life style and environmental factors influence the methylation in the genome. Scientists have already well documented links between the methylation status of specific positions in the genome and cancer as well as other diseases.

Cellular jetlag seems to favor the development of diabetes
Like almost all light-sensitive living beings, human beings follow biological rhythms set on a period of about 24 hours. The circadian clock (from Latin "circa" and "dies", which means "about a day") therefore describes the internal system that allows us to anticipate the changes of day and night by regulating nearly all the aspects of our physiology and behaviour. At a time when our biological rhythms are increasingly undermined - whether by night work, jetlag, or societal habits, - scientists begin to unveil the impact such circadian misalignments may have in the explosion of metabolic diseases. Specialists from the University of Geneva (UNIGE) and the University Hospitals of Geneva (HUG) studied pancreatic ɑ- and β- cells that are in charge of the production of insulin and glucagon, two hormones that regulate glucose levels in the blood. They discovered that already at cellular levels, these internal clocks orchestrate the timing of proper hormone secretion, thus optimizing body metabolism by anticipating the rest-activity and feeding-fasting cycles. Their misalignment would thus favor the occurrence of metabolic diseases.

For atrial fibrillation ablation, newer anticoagulant reduces major bleeds
Uninterrupted treatment with dabigatran, a non-vitamin K antagonist oral anticoagulant (NOACs), before, during and after ablation to treat atrial fibrillation significantly reduced the incidence of major bleeding events compared with uninterrupted use of the more established anticoagulant warfarin, according to research presented at the American College of Cardiology's 66th Annual Scientific Session.

Poison centers receive 32 calls a day about kids exposed to prescription opioids
A new study published online today by Pediatrics and conducted by the Center for Injury Research and Policy and the Central Ohio Poison Center at Nationwide Children's Hospital found that there were more than 188,000 calls to US Poison Control Centers for pediatric exposure to opioids from January 2000 through December 2015, averaging 32 calls a day or one every 45 minutes.

Evolocumab significantly reduces risk of cardiovascular events
Evolocumab, one of the new targeted PCSK9 inhibitor drugs that has been shown to dramatically lower levels of low-density lipoprotein (LDL), or "bad" cholesterol, also significantly lowers the risk of cardiovascular events in patients with existing heart or vascular disease already on statin therapy, according to research presented at the American College of Cardiology's 66th Annual Scientific Session.

Black Americans more likely to skip flu shot
(HealthDay)—More than half of American adults don't get an annual flu shot, and black Americans are even less likely to do so because of concerns about side effects, researchers report.

Now hear this: Loud sound may pose more harm than we thought
Matt Garlock has trouble making out what his friends say in loud bars, but when he got a hearing test, the result was normal. Recent research may have found an explanation for problems like his, something called "hidden hearing loss."
