Dedicated palliative care consults improve outcomes

Data from a long-term care facility in the USA indicate that a dedicated palliative care consult service results in a more favorable course of treatment and clinical outcomes for residents.

Arthritis, rheumatism and total joint arthroplasty: an interview with Dr Ravi and Dr Hawker

Arthritis translates to “joint inflammation.” The most common form of arthritis is osteoarthritis (OA), which affects 12-15% of North Americans over the age of 60, and will increase in prevalence as our population ages.

Myostatin responsible for initiation of muscle loss: Study

A research study from Nanyang Technological University (NTU) has yielded important breakthroughs on how the body loses muscle, paving the way for new treatments for aging, obesity and diabetes.

Link between silent stroke and Parkinson's disease

Scientists at The University of Manchester have for the first time identified why a patient who appears outwardly healthy may develop Parkinson's disease.

BubR1 and its associated regulators promising targets for aging disorders and cancer

A new series of studies in mouse models by Mayo Clinic researchers uncovered that the aging process is characterized by high rates of whole-chromosome losses and gains in various organs, including heart, muscle, kidney and eye, and demonstrate that reducing these rates slows age-related tissue deterioration and promotes a healthier life span. The findings appear in today's online issue of Nature Cell Biology.

Germ cell removal may promote longevity

The gonad is well known to be important for reproduction but also affects animal life span. Removal of germ cells - the sperm and egg producing cells - increases longevity of the roundworm Caenorhabditis elegans. However, the underlying molecular mechanisms were a mystery. Now scientists at the Cologne-based Max Planck Institute for Biology of Ageing, have discovered that germ cell removal flips a "molecular switch" that extends the life span by using components of a "developmental clock".

Osteoporosis screening: an interview with Professor Cyrus Cooper

Osteoporosis is defined as a reduction in bone mass coupled with micro-architectural deterioration of bone tissue which predisposes to fractures. Osteoporosis manifests through an increased risk of fracture, and age-related fractures are a major public health problem.

Healthy behavior at middle age is critical to 'successful' aging

Observing a combination of healthy behaviors during middle age, including moderate exercise and alcohol intake, and not smoking, can significantly improve the chances of aging successfully, study findings show.

Scientists discover new gene mechanism that appears to regulate triglyceride levels

Scientists at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University have discovered a new gene mechanism that appears to regulate triglyceride levels.

Researchers identify how RecA protein helps broken DNA find way to bridge the gap

Every time a human or bacterial cell divides it first must copy its DNA. Specialized proteins unzip the intertwined DNA strands while others follow and build new strands, using the originals as templates. Whenever these proteins encounter a break - and there are many - they stop and retreat, allowing a new cast of molecular players to enter the scene.

Harmonic generation microscopy can help measure natural age-related changes in skin cells

Wrinkles, dryness, and a translucent and fragile appearance are hallmarks of old skin, caused by the natural aging of skin cells. But while most of us can recognize the signs of lost youth when we peer into the mirror each morning, scientists do not have a standardized way to measure the extent of age damage in skin. Now a group of Taiwanese researchers has used a specialized microscope to peer harmlessly beneath the skin surface to measure natural age-related changes in the sizes of skin cells.

In shadow of fiscal cliff, other congressional activity on health care goes on

On Capitol Hill, various members and committees are writing letters to the administration or proposing legislation.

Researchers use nanotechnological approach to transform rattan wood into implants

Could ageing and damaged bones be replaced with implants based on wood? That's the question Italian researchers from the National Research Council of Italy (CNR) writing in a forthcoming issue of the International Journal of Healthcare Technology and Management hope to answer.

Roundup: Mass. a template for controlling health care costs?; Fewer than expected use Minn. health care vouchers; Blue Shield in Calif.'s proposed rate hikes

This simple shift in how health care is paid for -- long seen as key to taming costs -- has been occurring in pockets of the country. But nowhere is it happening more systematically than in Massachusetts, the state that blazed a trail in 2006 by guaranteeing its residents health insurance. Now Massachusetts, a model for President Obama's 2010 national health care law, may offer another template for national leaders looking to control health spending.

Survey finds serious shortfalls in quality of mental health care for older adults

Large majorities of older Americans with depression, anxiety, or other mental health disorders are receiving treatment that does not meet evidence-based standards, and many do not know that depression can put their health at increased risk, according to a national survey, "Silver and Blue: The Unfinished Business of Mental Health Care for Older Adults," released today by the John A. Hartford Foundation.

Oncogene-induced senescence could play a key role in future cancer therapy

Cell aging, or cellular senescence, has an important role in the natural physiological response to tumor development. Activated oncogenes are able to induce senescence, and recent findings have suggested that oncogene-induced senescence (OIS) could play a key role in future cancer therapy.

Activated astrocytes could play a harmful role in Alzheimer's disease

A research team composed of University of Kentucky researchers has published a paper which provides the first direct evidence that activated astrocytes could play a harmful role in Alzheimer's disease.

SIRT6 protein may play a critical role in blocking cancer and controlling cellular metabolism

A new study sheds more light on how an anti-aging gene suppresses cancer growth, joint University of Michigan Health System and Harvard Medical School research shows.

AC253 drug appears to restore memory in Alzheimer's brain cells

Medical researchers at the University of Alberta have discovered a drug intended for diabetes appears to restore memory in Alzheimer's brain cells.

Roundup: NH hospital at center of hepatitis outbreak details fixes; Report finds racial gap in Colo. dental coverage; Health cuts part of Conn. budget plan

Though Exeter Hospital has fixed problems discovered after a hepatitis C outbreak last spring, federal officials say the hospital initially failed to conduct an adequate investigation. The Centers for Medicare and Medicaid Services said last week it no longer plans to terminate the hospital's Medicare funding now that multiple issues raised by inspectors have been addressed.
