Although sexual dysfunction is not a specific symptom of posttraumatic stress disorder (PTSD), it is a frequent complaint among trauma survivors. The Journal of Sexual Medicine review finds that PTSD-related biological and cognitive processes may contribute to the development of sexual dysfunction following traumatic stress. The authors note that trauma exposure can profoundly rupture an individual's sense of safety and the ability to trust and feel connected to others. It may result in an association of arousal with threat. "It is clear that PTSD is associated with ...

WASHINGTON, D.C. - The gases used to knock out surgery patients are accumulating in the Earth's atmosphere, where they make a small contribution to climate change, report scientists who have detected the compounds as far afield as Antarctica. Over the past decade, concentrations of the anesthetics desflurane, isoflurane and sevoflurane have been rising globally, the new study finds. Like the well-known climate warmer carbon dioxide, anesthesia gases allow the atmosphere to store more energy from the Sun. But unlike carbon dioxide, the medical gases are extra potent in ...

In a recent study, females with eating disorders in late adolescence were more likely to have lower levels of educational attainment and personal income in early adulthood. They were also less likely to own a home. These associations were not seen in males. Disordered eating behaviors may set some individuals on a different trajectory whereby they do not have the same life chances or opportunities for success in adulthood. "Although the negative physical and mental health consequences of eating disorders have been well documented, much less is known about the adult ...

Sustainable rooftop technologies--including green roofs, white roofs, and solar photovoltaic panels--can provide great environmental benefits, but studies of these technologies often look only at their use in hot climates and do not assess their full environmental consequences. A new study that compares the technologies in the cold Canadian climate shows that photovoltaic panels demonstrate the highest environmental performance in all impact categories considered and is the preferred option from an environmental perspective. Green roofs result in fewer beneficial environmental ...

The number of gorillas and chimpanzees in Central Africa continues to decline due to hunting, habitat loss, and disease, combined with a widespread lack of law enforcement and corruption in the judicial process, according to the International Union for Conservation of Nature, Wildlife Conservation Society, WWF, and partners in a new conservation plan. A new report--titled "Regional Action Plan for the Conservation of Western Lowland Gorillas and Central Chimpanzees 2015-2025"--outlines the growing number of threats to these great apes across six range countries, including ...

Uninsured cancer patients are asked to pay anywhere from two to 43 times what Medicare would pay for chemotherapy drugs, according to a new study from the University of North Carolina at Chapel Hill. Researchers led by Stacie Dusetzina, an assistant professor in the Eshelman School of Pharmacy and the Gillings School of Global Public Health, reviewed newly available Medicare data on what physicians charged for chemotherapy drugs delivered intravenously in 2012. Uninsured patients who did not negotiate the billed amounts could expect to pay $6,711 for an infusion of ...

TAMPA, Fla. - Lung cancer is the second most common type of cancer and the number one cause of cancer-related mortality. It is estimated that more than 158,000 people will die from lung cancer in the United States this year. Many scientists believe that targeting a type of cell called a cancer stem cell may be necessary to completely cure lung cancer. Moffitt Cancer Center researchers discovered a novel mechanism that plays an important role in the maintenance of lung cancer stem cells. This finding may lead to new potential therapeutic targets. Cancer stem cells are ...

Among a sample of veterans in Connecticut, a substantial number had individuals listed as next of kin who were not nuclear family members, according to a study in the April 7 issue of JAMA. State default consent statutes do not universally recognize such persons as decision makers for incapacitated patients. For patients who lose capacity and have no legally appointed surrogate decision maker, most states have laws that specify a hierarchy of persons who may serve as surrogate decision makers by default. A patient's spouse is usually given priority, followed by adult ...

WASHINGTON D.C., April 7, 2015 - As we approach the miniaturization limits of conventional electronics, alternatives to silicon-based transistors--the building blocks of the multitude of electronic devices we've come to rely on--are being hotly pursued. Inspired by the way living organisms have evolved in nature to perform complex tasks with remarkable ease, a group of researchers from Durham University in the U.K. and the University of São Paulo-USP in Brazil is exploring similar "evolutionary" methods to create information processing devices. In the Journal of ...

PHILADELPHIA - In a study involving more than 31,000 women with cancer-causing mutations in the BRCA1 or BRCA2 genes, researchers at The Basser Center for BRCA, the Abramson Cancer Center, and the Perelman School of Medicine at the University of Pennsylvania identified mutations that are associated with significantly different risks of breast and ovarian cancers. Authors say the results - which show that some mutations confer higher risks of breast cancer, while other mutations show higher risks of ovarian cancer - may lead to more effective cancer risk assessment, care ...

Bodies found in a 200 year-old Hungarian crypt have revealed the secrets of how tuberculosis (TB) took hold in 18th century Europe, according to a research team led by the University of Warwick. A new study published in Nature Communications details how samples taken from naturally mummified bodies found in an 18th century crypt in the Dominican church of Vác in Hungary have yielded 14 tuberculosis genomes, suggesting that mixed infections were common when TB was at peak prevalence in Europe. The research team included collaborators from the Universities of Warwick ...

DURHAM, N.C. -- In the four years following the 2008 recession, the coal industry lost more than 49,000 jobs, while the natural gas, solar and wind industries together created nearly four times that amount, according to a new Duke University study. A county-by-county geographical analysis of the losses and gains shows that few new jobs were added in regions hardest hit by coal's decline, particularly counties in southern West Virginia and eastern Kentucky. "Our study shows it has not been a one-for-one replacement," said senior author Lincoln Pratson. "The counties ...

ROSEMONT, Ill.--A new study appearing in the April issue of The Journal of Bone & Joint Surgery (JBJS), found that most patients who underwent surgery to repair and rebuild an anterior cruciate ligament (ACL) tear, showed significant improvement in physical function at two years, which continued for at least six years following surgery. Younger patient age, lower body mass index (BMI), and having the remnants of the torn ACL completely excised during surgery, were among the strongest predictors of positive, long-term outcome. With over 200,000 incidents per year in the ...

It is well known that bumblebees and other pollinators can tell the difference between plants that will provide them with nectar and pollen and those that won't. However, until now little has been known about how the arrangement of flowers affects their decision making. Researchers from the School of Biological and Chemical Sciences at Queen Mary University of London, taught bumblebees to distinguish between two visually clearly different feeder types, one type containing food while the other did not. They found that bees were able to quickly learn the feeder types containing ...

A particular genetic mutation combined with an urban environment increases the risk of severe disease in children infected with respiratory syncytial virus (RSV), an international team of investigators has found. RSV infects half of the infants in the world every year, and 1 percent to 2 percent of infected infants are hospitalized for severe disease. The study, reported in the Journal of Clinical Investigation, identifies a specific sub-population of children who are more likely to be hospitalized because of RSV infection, said Fernando Polack, M.D., Cesar Milstein ...

With obesity on the rise in households across America, the demand for weight-loss treatments, personal trainers, and lifestyle coaches is amping up. But when it comes to physical fitness, the best incentive to get in shape might be the very person sitting across from you at the dinner table. New research finds that exercising isn't only good for you - it is also good for your spouse. According to Dr. Silvia Koton of the Department of Nursing at Tel Aviv University's Sackler Faculty of Medicine, lead investigator Dr. Laura Cobb, and their colleagues at the Johns Hopkins ...

WASHINGTON --Abdominal pain, fever and unexplained bleeding - which are commonly believed to indicate infection with the Ebola virus -- are not significantly predictive of the disease, according to the results of a study examining a new Ebola Prediction Score published online Friday in Annals of Emergency Medicine ("Derivation and Internal Validation of the Ebola Prediction Score for Risk Stratification of Patients with Suspected Ebola Virus Disease"). "Not surprisingly, contact with a suspected or confirmed Ebola patient was the strongest independent predictor of having ...

Single women seeking treatment with donor semen do not differ from cohabiting women seeking treatment with regard to sociodemographic characteristics or attitudes toward motherhood, a new study of 311 Danish women shows. For most, to be a single mother by choice is not their preferred way of parenthood, but rather a solution they need to accept as they get older. The findings may help dispel the myth that single women are in anyway less suited to motherhood than those who live with a spouse. "Various family formations are a normal part of the Danish society, but data ...

The term "sarcopenia" is most often used to describe age-related loss in muscle mass and strength, and it is commonly considered analogous to osteoporosis. Yet unlike osteoporosis, which can be diagnosed based on widely accepted clinical criteria, sarcopenia is not recognized as a clinical condition even though it can impair physical function and contribute to disability, falls, and hospitalizations. A new review addresses this concern and points to efforts aimed at developing and refining sarcopenia criteria. "For over 20 years, the lack of a consensus definition ...

The use of asbestos continues to increase in Asia despite clear health hazards. A recent Respirology review notes that with approximately 4.3 billion people and a growing population, Asia will likely see a large crop of asbestos-related lung diseases in the next few decades. Some of the cases will be benign, but it is likely that there will be many cases of mesothelioma and lung cancer. Efforts are needed to improve the recognition and diagnosis of asbestos-related lung diseases, and government and non-government groups must cooperate to take steps to prevent them. INFORMATION: ...

The number of individuals enrolled in both Medicare Advantage (MA) and the Veterans Affairs (VA) health system nearly doubled from 2004 to 2009, and such dual enrollees are expected to increase in number following the full implementation of the Affordable Care Act. Because both the VA and MA are federally funded managed care systems, expenditures are duplicated for individuals who are dually enrolled. A new Health Services Research study has found that while dual use does not appear to erode quality of care, there's also no evidence that it improves it. INFORMATION: ...

The fixed combination of the drugs tafluprost and timolol (trade name: Taptiqom) has been approved in Germany since December 2014 for adults with open-angle glaucoma or increased intraocular pressure (ocular hypertension). The combination therapy is indicated in patients who are insufficiently responsive to topical monotherapy with beta-blockers or prostaglandin analogues, and who would benefit from preservative-free eye drops. The German Institute for Quality and Efficiency in Health Care (IQWiG) examined in a dossier assessment whether this drug combination offers an ...

We age in part thanks to "friendly fire" from the immune system -- inflammation and chemically active molecules called reactive oxygen species that help fight infection, but also wreak molecular havoc over time, contributing to frailty, disability and disease. The CD33rSiglec family of proteins are known to help protect our cells from becoming inflammatory collateral damage, prompting researchers at the University of California, San Diego School of Medicine to ask whether CD33rSiglecs might help mammals live longer, too. In a study published April 7 by eLife, the team ...

Viagra and other related drugs are not a universal 'cure-all' for impotence, according to a new study from The University of Manchester and NatCen Social Research. Drugs, clinically known as oral phosphodiesterase type 5 inhibitors (PDE5i), have become the first-line medical treatment option for sufferers of erectile dysfunction (ED) - also known as impotence - since entering the UK market in 1998. An abundance of studies has demonstrated the effectiveness of such drugs. But researchers at The University of Manchester, who have studied the responses of more than 2,600 ...

Cancer researchers from the University of Zurich have identified a key signaling pathway in B-cell lymphoma, a malignant type of blood cancer. They demonstrate that the signaling pathway can be blocked using compounds that are already in clinical development. This finding might be extremely important for the diagnosis, prognosis and treatment of this disease in the future. Diffuse large B-cell lymphoma (DLBCL) is a blood cancer and the most common malignant condition of the lymphatic system. Although DLBCL is always fatal if left untreated, the cure rate after chemo-therapy ...
