Blue light goggles improve sleep quality in the elderly

Sleep disturbances increase as we age. Some studies report more than half of seniors 65 years of age or older suffer from chronic sleep disturbances. Researchers have long believed that the sleep disturbances common among the elderly often result from a disruption of the body's circadian rhythms - biological cycles that repeat approximately every 24 hours.

Pressure to look 'attractive' provokes negative outcomes

People who feel pressure to look attractive are more fearful of being rejected because of their appearance than are their peers, according to a new study by researchers at the University at Buffalo and the University of Kent.

Linking microRNAs with cells that regulate the immune system could lead to new disease therapies

Linking genetic material microRNAs with cells that regulate the immune system could one day lead to new therapies for treating cancer, infections and autoimmune diseases, according to a Henry Ford Hospital study.

Taking a break from hormones doesn't improve mammograms

Some women take a short break from using postmenopausal hormone therapy before getting their breasts screened for cancer with mammography. They hope to lower their risk of being called back afterward for unnecessary extra breast imaging. But taking a short break from hormones doesn't actually work for this purpose, according to the first large-scale randomized controlled trial to address the question. The READ (Radiological Evaluation and Breast Density) trial of more than 1,700 Group Health women is in the June 2, 2009 Annals of Internal Medicine.

Impact of Medicare Part D on access to and cost sharing for specialty biologic medications for beneficiaries with rheumatoid arthritis

Biologic disease-modifying antirheumatic drugs (DMARDs) such as adalimumab, etanercept and infliximab are effective at reducing symptoms and slowing progression of rheumatoid arthritis (RA). These drugs act more quickly, require less laboratory monitoring, and are better tolerated than nonbiologic DMARDs, but they are also up to 100 times more expensive.

New method to induce protein folding

A new method to induce protein folding by taking the pressure off of proteins is up to 100 times faster than previous methods, and could help guide more accurate computer simulations for how complex proteins fold, according to research by a team of University of Illinois scientists accepted for publication in the journal Nature Methods and posted on the journal's Web site May 31.

Research looks at relationship between bone density and erosion in arthritis

Rheumatoid arthritis (RA), the most common form of inflammatory arthritis, affects almost three percent of people over age 65. RA patients experience pain, functional limitations and two forms of disabling bone disease: focal erosions and osteoporosis.

Pay-for-performance may benefit doctors who care for multiple health problems

Physicians who treat patients with multiple health problems will fare well under pay-for-performance, which bases physician reimbursement on the quality of care provided, said researchers at Baylor College of Medicine and the Michael E. DeBakey Veterans Affairs Medical Center in Houston in a report in the current issue of the journal Circulation.

Vandetanib shows clinical benefit when combined with docetaxel for lung cancer

When combined with standard chemotherapy, an international Phase III trial has shown that the oral targeted therapy vandetanib improves progression-free survival for patients with advanced non-small cell lung cancer, according to research from The University of Texas M. D. Anderson Cancer Center.

Discovery of gene that regulates tumors in neuroblastoma

Virginia Commonwealth University researchers have identified a gene that may play a key role in regulating tumor progression in neuroblastoma, a form of cancer usually found in young children. Scientists hope the finding could lead to an effective therapy to inhibit the expression of this gene.

Citalopram no more effective than a placebo for children with autism spectrum disorders

Citalopram, a medication commonly prescribed to children with autism spectrum disorders (ASD), was no more effective than a placebo at reducing repetitive behaviors, according to researchers funded by the National Institute of Mental Health (NIMH) and other NIH institutes. The study was published in the June 2009 issue of Archives of General Psychiatry.

The effectiveness of Tai Chi for chronic musculoskeletal pain conditions

The results of a new analysis have provided good evidence to suggest that Tai Chi is beneficial for arthritis. Specifically, it was shown to decrease pain with trends towards improving overall physical health, level of tension and satisfaction with health status.

Eye cancer patients want genetic testing to predict metastasis risk

If you had cancer and a genetic test could predict the risk of the tumor spreading aggressively, would you want to know - even if no treatments existed to help you?

Rapamycin epilepsy-prevention effect may be widely applicable

A drug with potential to prevent epilepsy caused by a genetic condition may also help prevent more common forms of epilepsy caused by brain injury, according to researchers at Washington University School of Medicine in St. Louis.

Exploiting cancer cell 'addiction' may lead to new therapies

A new study uncovers a gene expression signature that reliably identifies cancer cells whose survival is dependent on a common signaling pathway, even when the cells contain multiple other genetic abnormalities.

Findings in epilepsy gene in animals may guide treatment directions for infants

Researchers studying a difficult-to-treat form of childhood epilepsy called infantile spasms have developed a line of mice that experiences seizures with features closely resembling those occurring in patients with infantile seizures. These genetically engineered mice provide a new opportunity for scientists to test treatments that may benefit children.

Glioblastoma may originate in neural stem cells

University of Michigan scientists have found that a deficiency in a key tumor suppressor gene in the brain leads to the most common type of adult brain cancer. The study, conducted in mice that mimic human cancer, points the way to more effective future treatments and a way to screen for the disease early.

17 million U.S. children live over an hour away from a pediatric trauma center

More than 17 million U.S. children live more than an hour away by ground or air transportation from a life-saving pediatric trauma center, according to a new study by researchers at The Children's Hospital of Philadelphia and the University of Pennsylvania. The creation of a national inventory of pediatric trauma centers may help to identify the locations of gaps and greatly improve access to care for U.S. children, the authors said.

Smoking and genetics play role in rheumatoid arthritis

Recent genetic studies have revealed several new sites of genes that are risk factors for developing rheumatoid arthritis (RA).

Oligophrenin-1 signaling protein linked to mental retardation controls synapse maturation, plasticity

A team of neuroscientists at Cold Spring Harbor Laboratory (CSHL) has demonstrated the mechanism by which a signaling protein found throughout the brain controls the maturation and strength of excitatory synapses, the tiny gaps across which the majority of neurons communicate.
