National heart organizations join to combat the global hypertension epidemic

NEW YORK, N.Y., May 19, 2014: It's estimated that more than 970 million people have hypertension1 and, globally, the disease is responsible for more than nine million deaths every year, making it one of the leading causes of death worldwide.

Chronic insufficient sleep increases obesity, overall body fat in children

One of the most comprehensive studies of the potential link between reduced sleep and childhood obesity finds compelling evidence that children who consistently received less than the recommended hours of sleep during infancy and early childhood had increases in both obesity and in adiposity or overall body fat at age 7. The study from MassGeneral Hospital for Children (MGHfC) investigators, published in the June issue of Pediatrics, also finds no evidence of a specific period during which insufficient sleep has greater influence on later obesity.

Low risk prostate cancer not always low risk

More and more men who believe they have low-risk prostate cancers are opting for active surveillance, forgoing treatment and monitoring the cancer closely with prostate-specific antigen (PSA) tests, digital rectal exams and ultrasounds at regular intervals to see if their tumors are growing. Nearly 400 men are now enrolled in the UCLA Active Surveillance program, the largest in Southern California.

Shorter lives for male fruit flies forced to compete

LIVERPOOL, UK – 9 May 2014: A University of Liverpool study of fruit flies has revealed that males forced to compete with other males become less attractive to females and die young.

In the test, male fruit flies of the species Drosophila subobscura were kept either alone or in groups. The females of this species are monandrous – they only mate once in their lives, meaning that males have to get very lucky to mate at all. As a result males compete furiously for access to females.

One small chip -- one giant leap forward for early cancer detection

Today, the majority of cancers are detected on the macroscopic level, when the tumor is already composed of millions of cancer cells and the disease is starting to advance into a more mature phase. But what if we could diagnose cancer before it took hold- while it was still only affecting a few localized cells? It would be like putting a fire out while it was still just a few sparks versus after having already caught on and spread to many areas of the house.

E-cigarettes may boost resistance of drug-resistant pathogens

ATS 2014, SAN DIEGO ─ Despite being touted by their manufacturers as a healthy alternative to cigarettes, e-cigarettes appear in a laboratory study to increase the virulence of drug- resistant and potentially life-threatening bacteria, while decreasing the ability of human cells to kill these bacteria

Higher temperatures may cause greater illness among COPD patients

ATS 2014, SAN DIEGO ─ If you suffer from COPD, staying cool this summer may provide much more significant benefits than simply feeling more comfortable. A study from researchers at Johns Hopkins University says it may also keep you healthier. The study found COPD patients who were exposed to warm indoor temperatures had greater disease-related morbidity, including an increase in symptoms, a rise in the use of rescue medications and a decline in lung function. Higher outdoor temperatures were also associated with increased COPD symptoms.

Vitamin D supplementation does not improve asthma treatment, symptoms

In adults with persistent asthma and low vitamin D levels, treatment with vitamin D3 did not reduce the rate of treatment failure or exacerbation of symptoms, according to a study published by JAMA. The study is being released early online to coincide with its presentation at the American Thoracic Society International Conference.

For pregnant smokers, vitamin C supplements improve lung function of newborn

Supplemental vitamin C taken by pregnant smokers improved measures of lung function for newborns and decreased the incidence of wheezing for infants through 1 year, according to a study published by JAMA. The study is being released early online to coincide with its presentation at the American Thoracic Society International Conference.

Cedars-Sinai study identifies heart-specific protein that protects against arrhythmia

LOS ANGELES – Researchers at the Cedars-Sinai Heart Institute have identified a heart-specific form of a protein, BIN1, responsible for sculpting tiny folds in pockets that are present on the surface of heart muscle cells. The study provides the first direct evidence of a previously theoretical "fuzzy space" or "slow diffusion zone" that protects against irregular heartbeats by maintaining an ideal concentration of electrochemical molecules.

Cutoff switch may limit spread, duration of oxygen minimum zones

CORVALLIS, Ore. – A new study examining the impact of iron released from continental margin sediments has documented a natural limiting switch that may keep these ocean systems from developing a runaway feedback loop that could lead to unchecked hypoxic areas, or persistent "dead zones."

Urine test could help clinicians spot blood clots in at-risk patients

ATS 2014, SAN DIEGO ─ A new study by researchers from California and Canada indicates a simple urine test can indicate the presence of venous thromboembolism, a blood clot that has broken free from its point of origin and which travels through the bloodstream, eventually lodging in a vein. The test evaluates the levels of fibrinopeptide B (FPB), a small peptide that's released when a thrombosis forms and which is removed from the body through urine.

The results of the study will be presented at the American Thoracic Society's 2014 International Conference here.

Bacteria in mouth may diagnose pancreatic cancer

Patients with pancreatic cancer have a different and distinct profile of specific bacteria in their saliva compared to healthy controls and even patients with other cancers or pancreatic diseases, according to research presented today at the annual meeting of the American Society for Microbiology. These findings could form the basis for a test to diagnose the disease in its early stages.

Temple-led study finds no benefit in taking statin drugs for COPD exacerbation prevention

(Philadelphia, PA) – A statin drug commonly used to lower cholesterol is not effective in reducing the number and severity of flare ups from chronic obstructive pulmonary disease (COPD), according to the results of a large multicenter clinical trial designed and directed by Gerard J. Criner, MD, Director of Pulmonary and Critical Care Medicine at Temple University Hospital in Philadelphia, PA.

Painkillers may decrease susceptibility to recurring urinary infections

Women plagued by repeated urinary tract infections may be able to prevent the infections with help from over-the-counter painkillers, according to research presented at the annual meeting of the American Society for Microbiology.

Scientists at Washington University School of Medicine in St. Louis found that inhibiting COX-2, an immune protein that causes inflammation, eliminated recurrent urinary tract infections in mice. COX-2 is one of the proteins blocked by non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen.
