Many women experience bothersome urine loss with laughing, coughing and sneezing (stress urinary incontinence) AND on their way to the bathroom (urge urinary incontinence). When women experience both types of urine leakage, their condition is called mixed urinary incontinence. It is estimated that 20 to 36 percent of women suffer from mixed urinary incontinence, which is challenging to diagnose and treat because symptoms vary and guidelines for treatment are not clear.

Improved diagnosis and management of one of the most common cancers in men – prostate cancer – could result from research at the University of Adelaide, which has discovered that seminal fluid (semen) contains biomarkers for the disease.

Research carried out by the Copenhagen Centre for Team Sport and Health in Denmark shows that untrained elderly men get markedly fitter and healthier as a result of playing football (soccer). After only 4 months of twice-weekly 1-hour training sessions, the men achieved marked improvements in maximum oxygen uptake, muscle function and bone mineralization.

Scientists at the University of York are playing a key role in the quest for a better understanding of how a recently discovered family of enzymes can degrade hard-to-digest biomass into its constituent sugars.

The enzymes – lytic polysaccharide monooxygenases (LPMOs) – are secreted by both fungi and bacteria and have the ability to 'chip away' at cellulose and other intractable materials. This allows cellulosic materials such as plant stems, wood chips and cardboard waste, as well as other tricky polysaccharides such as insect/crustacean shells, to be broken down.

Boston, MA – Researchers have found the first evidence of an intercellular bacterial infection in natural populations of two species of Anopheles mosquitoes, the major vectors of malaria in Africa. The infection, called Wolbachia, has been shown in labs to reduce the incidence of pathogen infections in mosquitoes and has the potential to be used in controlling malaria-transmitting mosquito populations.

A large new analysis of DNA from thousands of patients has uncovered several underlying gene networks with potentially important roles in autism. These networks may offer attractive targets for developing new autism drugs or repurposing existing drugs that act on components of the networks.

Furthermore, one of the autism-related gene pathways also affects some patients with attention-deficit hyperactivity disorder (ADHD) and schizophrenia—raising the possibility that a class of drugs may treat particular subsets of all three neurological disorders.

WASHINGTON, DC (June 6, 2014) — More than 11 percent of smokers who used a text- messaging program to help them quit did so and remained smoke free at the end of a six- month study as compared to just 5 percent of controls, according to a new report by researchers at Milken Institute School of Public Health at the George Washington University (Milken Institute SPH.)

Infants exposed to rodent and pet dander, roach allergens and a wide variety of household bacteria in the first year of life appear less likely to suffer from allergies, wheezing and asthma, according to results of a study conducted by scientists at the Johns Hopkins Children's Center and other institutions.

Philadelphia, PA, June 6, 2014 – Scientists have identified four biomarkers that may help resolve the difficult differential diagnosis between malignant pleural mesothelioma (MPM) and non-cancerous pleural tissue with reactive mesothelial proliferations (RMPs). This is a frequent differential diagnostic problem in pleural biopsy samples taken from patients with clinical suspicion of MPM. The ability to make more accurate diagnoses earlier may facilitate improved patient outcomes. This new study appears in the Journal of Molecular Diagnostics.

YbeY is a conserved protein that is present in most bacteria. A study published on June 5th in PLOS Pathogens examines the function of YbeY in the cholera bacterium and reveals critical roles in RNA metabolism in this and other pathogenic bacteria.

June 5, 2014 – So-called silent DNA mutations earned their title because, according to the fundamental rules of biology, they should be inconsequential. Reported on June 5 in PLOS Genetics online, University of Utah researchers experimentally proved there are frequent exceptions to the rule. The work was conducted in the bacteria, Salmonella enterica, used to study basic biological mechanisms that are often conserved in humans.

BOSTON – June 5, 2014 - People with type 1 diabetes who have developed kidney complications can slow the progression of their complications by improving control of their glycemic (blood glucose) levels over the long term.

This finding, which may change clinical practice at many institutions for this population, was drawn from a long-term observational study led by Andrzej Krolewski, M.D., Ph.D., head of Joslin Diabetes Center's Section on Genetics and Epidemiology.

Who would you rather have as a fitness partner: a paragon of athleticism and dedication who could motivate you to exceed your current level of fitness or an equal, with whom you could exchange tips and encouragement on the road to better health?

Or neither? According to a new study led by University of Pennsylvania's Damon Centola, participants in an online fitness program ignored the fitness aptitude of their potential partners.

A new screening process for tuberculosis (TB) infections in Canadian prisons could mean that more than 50 per cent of those screened won't undergo unnecessary treatment due to false positives.

According to research by Wendy Wobeser and medical resident Ilan Schwartz, a test for TB using interferon-gamma release assays (IGRA) will detect a pre-existing TB infection, or latent TB, that might not present itself for many years, or until the body becomes weakened by another source.
