DURHAM, N.C. -- Whether it's an on-line quiz, a $300 chromosome test or an $800 blood panel, a lot of people seem to be interested in whether they're aging faster or slower than their chronological age would suggest.

Unfortunately, they're just going to have to wait and see.

A head-to-head comparison of 11 different measures of aging, including blood and chromosome tests like those being sold commercially, has found that they don't agree with one another on how fast a given person is growing older.

MINNEAPOLIS - Using virtual reality therapy to improve arm and hand movement after a stroke is equally as effective as regular therapy, according to a study published in the November 15, 2017, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Six attributes of primary care delivery are associated with high value, according to a new study: decision support for evidence-based medicine, risk-stratified care management, careful selection of specialists, coordination of care, standing orders and protocols, and balanced physician compensation. The findings are the result of a mixed methods study of diverse primary care practices that are well positioned for the shift toward medical reimbursement based on quality and efficient resource use rather than volume.

Nov. 15, 2017 -- The American Thoracic Society (ATS) and the Japanese Respiratory Society (JRS) have published additional clinical practice guidelines regarding four specific questions related to the diagnosis of lymphangioleiomyomatosis (LAM) and management of pneumothoraces in patients with LAM.

Text message reminders are a low-cost effective strategy for increasing rates of influenza vaccination. A randomized controlled trial in Western Australia identified patients who were at high risk of serious influenza illness and had a mobile phone number on record in their physician's office. Among 12,354 eligible patients, half were randomly assigned to an intervention group, which received a vaccination reminder by text message, while the other half (control group) received no text message reminder.

A new study focused on describing genetic variations within a primary tumor, differences between the primary and a metastatic branch of that tumor, and additional diversity found in tumor DNA in the blood stream could help physicians make better treatment choices for patients with gastric and esophageal adenocarcinoma.

Many Pacific Island nations will lose 50 to 80 percent of marine species in their waters by the end of the 21st century if climate change continues unchecked, finds a new Nippon Foundation-Nereus Program study published in Marine Policy. This area of the ocean is projected to be the most severely impacted by aspects of climate change.

A study led by investigators at Massachusetts General Hospital (MGH) and University Health Network (UHN) in Toronto has identified a molecular pathway that appears to be critical to the development of fibrosis - scarring and excessive tissue deposition that result from abnormal healing responses and can compromise the function of vital organs.

Older patients who experience more discontinuity of care in general practice are at higher risk of emergency hospital admissions. In a UK study of 10,000 randomly selected patients over age 65, medical records were linked with hospital episode statistics. The study used two research approaches: a prospective cohort approach to assess the general impact of continuity of care on emergency admission, and a nested case-control approach to test if seeing a different GP from usual increases the risk of emergency admission during the following 30 days.

The blood-brain barrier - the semi-permeable membrane that surrounds the brain - offers important protection for a delicate organ, but in some cases, clinicians need to get past the barrier to deliver vital drugs to treat the brain. Researchers at Brigham and Women's Hospital are investigating a way to temporarily loosen the blood-brain barrier to deliver drugs with the assistance of microbubbles. In a new advancement, they have developed a system in preclinical models that offers a finer degree of control - and, therefore, safety - in opening the barrier.
