Study uses GPS technology to predict football injuries Posted: 02 Aug 2016 07:22 PM PDT Soccer players' injuries may be predicted by looking at players' workloads during training and competition, according to new research. Researchers discovered that the greatest injury risk occurred when players accumulated a very high number of short bursts of speed during training over a three-week period.

At least 1 in 10 young people in Britain report a recent distressing sexual problem Posted: 02 Aug 2016 07:22 PM PDT Around one in 10 young men and one in eight young women in Britain who are sexually active have experienced a distressing sexual problem lasting at least three months in the past year, according to new research.

Alcohol advertising linked to adolescent drinking Posted: 02 Aug 2016 07:22 PM PDT A new study finds that exposure to several different types of alcohol marketing is positively associated with the amount and frequency of drinking among adolescents across Europe.

Where there's smoke -- and a mutation -- there may be an evolutionary edge for humans Posted: 02 Aug 2016 04:26 PM PDT A genetic mutation may have helped modern humans adapt to smoke exposure from fires and perhaps sparked an evolutionary advantage over their archaic competitors, including Neanderthals, according to a team of researchers.

Discovery of male-harming DNA mutation reinforces 'mother's curse' hypothesis Posted: 02 Aug 2016 02:18 PM PDT A male-harming DNA mutation has been discovered in Drosophila that demonstrates that the 'mother's curse' -- the possibility that moms may transmit genes to their children that harm their sons but not their daughters - holds true in animals.

Caring for elderly stroke survivors costs an estimated $40 billion per year Posted: 02 Aug 2016 02:18 PM PDT It's assumed that family and friends will help out in the event of a medical crisis, but that's not always feasible. And when stroke survivors need more than 20 hours of care per week, as a study shows, it's a large burden for their loved ones.

CDC issues travel guidance related to Miami neighborhood with active Zika spread Posted: 02 Aug 2016 12:20 PM PDT New assessments of mosquito populations and test results this past weekend by Florida public health officials, as part of a community survey in the Miami neighborhood where several Zika infections were recently confirmed, have found persistent mosquito populations and additional Zika infections in the same area. This information suggests that there is a risk of continued active transmission of Zika virus in that area. As a result, CDC and Florida are issuing travel, testing and other recommendations for people who traveled to or lived in the Florida-designated areas on or after June 15, 2016, the earliest known date that one of the people could have been infected with Zika.

Flexible wearable electronic skin patch offers new way to monitor alcohol levels Posted: 02 Aug 2016 12:13 PM PDT Engineers at the University of California San Diego have developed a flexible wearable sensor that can accurately measure a person's blood alcohol level from sweat and transmit the data wirelessly to a laptop, smartphone or other mobile device. The device can be worn on the skin and could be used by doctors and police officers for continuous, non-invasive and real-time monitoring of blood alcohol content.

Research reveals cancer pathway to spreading through the body Posted: 02 Aug 2016 12:13 PM PDT Cancer cells need oxygen to survive, as do most other life forms, but scientists had never tracked their search for oxygen in their early growth stages until now -- a step toward a deeper understanding of one way cancer spreads that could help treat the disease.

Collateral harm: Impact of Ebola, related fears on facility-based child deliveries Posted: 02 Aug 2016 12:13 PM PDT The first known household survey examining the collateral harm to pregnancy services in areas affected by the West African Ebola epidemic suggests a significant slide backwards in child and maternal health. The study, conducted in Liberia, points to the deep disruptions caused by the Ebola epidemic, even in parts of the country with relatively limited transmission.

More accurate prostate cancer prognosis Posted: 02 Aug 2016 12:13 PM PDT Men diagnosed with prostate cancer can be provided with a more accurate estimate of their risk of death from the disease, and treatment planned accordingly, according to new research.

Study finds innate immunity connection to rare, fatal childhood disease Posted: 02 Aug 2016 10:37 AM PDT Researchers have found an important innate immunity role for a gene linked to a rare, fatal syndrome in children. Their study has implications for a much more common disease: tuberculosis.

Lack of pharmacy access sends some patients back to the hospital Posted: 02 Aug 2016 10:37 AM PDT Hospital readmissions, a $17 billion annual problem, are higher in rural, remote or smaller communities that sometimes have significantly less access to pharmacies, according to a study published today that was one of the first to examine this issue.

Underreporting of Zika is rife; researchers project epidemic's spread in certain countries Posted: 02 Aug 2016 10:37 AM PDT A new study reveals a large disparity between the number of reported and projected Zika cases. The researchers, responding to a 'call to arms' to model the spread of the virus, say that while a major US outbreak isn't projected, a certain set of countries in the Americas have the right conditions for "major outbreaks."

Combat exposure may jeopardize the behavioral health of women in the military Posted: 02 Aug 2016 10:01 AM PDT In a recent study, combat exposure among Army enlisted women was associated with an increased likelihood of developing behavioral health problems post-deployment, including post-traumatic stress disorder (PTSD), depression, and at-risk drinking.

Depression screening tools not accurate for children and adolescents Posted: 02 Aug 2016 09:56 AM PDT There is insufficient evidence to show that any of the short questionnaires used by physicians to ask about symptoms of depression accurately screen 6- to 18-year-olds for the disease.

Millennials less sexually active than Gen-X peers Posted: 02 Aug 2016 09:52 AM PDT Since time immemorial, older generations have fretted over the sexual habits of young people. In today's world, however, elders might just be wondering why young people are having so little sex. Researchers analyzed data from 26,707 respondents to the General Social Survey and found that today's young people are less likely to have had sex since turning 18.

Low rate of Internet use by seniors for health purposes Posted: 02 Aug 2016 09:52 AM PDT Researchers examined trends in seniors' use of digital health technology in the US from 2011-2014.

Treatments to improve kidney outcomes for patients with septic shock Posted: 02 Aug 2016 09:51 AM PDT Early use of vasopressin to treat septic shock did not improve the number of kidney failure-free days compared with norepinephrine, according to a new study.

Drug does not improve outcomes for patients with advanced heart failure Posted: 02 Aug 2016 09:51 AM PDT Among patients recently hospitalized with heart failure and reduced left ventricular ejection fraction (LVEF; a measure of heart function), the use of the drug liraglutide did not lead to greater post-hospitalization clinical stability, according to a new study.

Off-site monitoring of cardiac telemetry and clinical outcomes Posted: 02 Aug 2016 09:51 AM PDT Among non-critically ill patients, use of standardized cardiac telemetry with an off-site central monitoring unit was associated with detection and notification of cardiac rhythm and rate changes within one hour prior to the majority of emergency response team activations, and also with a reduction in the number of monitored patients, without an increase in cardiopulmonary arrest events, according to a new study.

Effective recovery in competitive sports Posted: 02 Aug 2016 08:28 AM PDT Researchers have studied the best possible regeneration measures for athletes after strenuous training and competition phases. Using blood tests, questionnaires and performance tests, they compared the effects different recovery measures have on top athletes and investigated if effective regeneration strategies for specific types of sport do exist. Their results are meant to help athletes and coaches choose different recovery measures in practice.

Cardiac complications from energy drinks? Case report adds new evidence Posted: 02 Aug 2016 08:27 AM PDT The high levels of caffeine in energy drinks may lead to cardiac complications, suggests a case report by experts. The case adds to previous reports of adverse cardiovascular events related to consuming energy drinks, including abnormal heart rhythms (arrhythmias).

Clinical usefulness of bone turnover marker concentrations in osteoporosis Posted: 02 Aug 2016 08:27 AM PDT A new review finds lack of comparability between current clinical assays for CTX is evident, indicating possible limitations of combining such data for meta-analyses; to improve interpretation of patient results harmonization of units for reporting serum/plasma CTX (ng/L) and PINP Further study of the relationships between clinical assays for CTX and PINP and physiological and pre-analytical factors contributing to variability in BTM concentrations is required.

Patented bioelectrodes have electrifying taste for waste Posted: 02 Aug 2016 08:27 AM PDT New research shows how Geobacter bacteria grow as films on electrodes and generate electricity -- a process that's ready to be scaled up to industrial levels.

Avoiding the high calorie office snacks Posted: 02 Aug 2016 07:42 AM PDT The culture of grabbing something quick to eat amid a mounting pile of to-dos at work often leads to making the wrong decisions when searching for something to eat in the workplace. Unplanned cake offerings and the emergence of 'food altars' – central places for leftovers from work meetings or unhealthy snacks present workers with a never-ending stream of choice. A recent study reveals water to be the main redeemer of 'negative nutrition' in the workplace.

No more dry mucous membranes when flying Posted: 02 Aug 2016 07:42 AM PDT Hovering at around 20 percent, the relative humidity in aircraft is kept very low to keep condensation from building up in the cabin. The downside for passengers and the crew is that this dries out the mucous membranes. Now a vortex ring generator will direct humidified air to passengers, increasing the humidity of the air they breathe without causing the overall relative humidity to skyrocket.

Hidden tooth infections may predispose people to heart disease Posted: 02 Aug 2016 07:41 AM PDT An infection of the root tip of a tooth increases the risk of coronary artery disease, even if the infection is symptomless. Hidden dental root tip infections are very common: as many as one in four in Finland suffer from at least one. Such infections are usually detected by chance from X-rays.

Neuroscience-based Framework for Addiction Diagnosis Posted: 02 Aug 2016 07:39 AM PDT When it comes to an addictive disorder, you either have it or you don't. But this dichotomous nature of the diagnosis fails to recognize the complexity and diversity of addiction's origins and manifestation in people. A new review proposes an Addictions Neuroclinical Assessment (ANA) to incorporate more clinical information into the diagnosis of addictive disorders.

Addiction silences synapses in reward circuits Posted: 02 Aug 2016 07:39 AM PDT In addiction, cues in the environment can form strong associations with the drug of abuse. A new study suggests that alterations in silent synapses, inactive connections between neurons, could be the neural mechanism underlying the formation of these drug-related memories. The alterations were found in the nucleus accumbens, a brain region involved in reward-related learning.

Exercise results in larger brain size and lowered dementia risk Posted: 02 Aug 2016 07:37 AM PDT Regular physical activity for older adults could lead to higher brain volumes and a reduced risk for developing dementia. It particularly affected the size of the hippocampus, which controls short-term memory, and its protective effect against dementia was strongest in people age 75 and older.

Simpler way to diagnose and understand childhood pneumonia infections Posted: 02 Aug 2016 07:35 AM PDT Researchers are developing a tool to make it much easier and cheaper to diagnose pneumonia -- the number one killer of children under 5. Currently, diagnosis requires X-ray and microbiology lab facilities -- unavailable in many areas of the world.

How naive T cells decline with age Posted: 02 Aug 2016 07:33 AM PDT The loss of naive T cells with age is from deterioration in the environment that supports T cells.

New light shed on causes of autoimmune disease Posted: 02 Aug 2016 07:33 AM PDT A new study reveals a surprising twist in immune biology, suggesting that members of a cluster of microRNAs work together throughout the different stages of immune cell generation.

Vaccines fail to protect obese mice from severe influenza infections Posted: 02 Aug 2016 07:33 AM PDT A new study found that obese mice are not protected against influenza infections by vaccines that include adjuvants, raising concerns about vaccine effectiveness in obese humans who are known to be at an increased risk for severe flu.

Researchers image brain cells' reactions to concussive trauma Posted: 02 Aug 2016 07:33 AM PDT Using a laboratory device that can deliver concussive impacts to cell cultures and image the aftermath in real time, researchers are gaining new insight into how brain cells react to trauma.
