$Hip and back fractures increase mortality rates in Seniors$

Hip and back fractures increase mortality rates in Seniors

If you are 50 or older and you break your hip, you have a one in four chance of dying within five years. Break your back, and you have a one in six chance of dying that soon, says a McMaster University study.

Flaw in bone's material leads to disease

The weak tendons and fragile bones characteristic of osteogenesis imperfecta, or brittle bone disease, stem from a genetic mutation that causes the incorrect substitution of a single amino acid in the chain of thousands of amino acids making up a collagen molecule, the basic building block of bone and tendon.

Universal intimate partner violence (IPV) screening may provide only modest benefits

New research suggests that universal intimate partner violence (IPV) screening in health care settings does not result in significant changes in subsequent reports of IPV or quality of life, according to a study in the August 5 issue of JAMA, a theme issue on violence and human rights.

Self-neglect and abuse in seniors linked to increased risk of death

Elderly individuals who have a report of self-neglect or abuse submitted to a social service agency have an associated increased risk of death, according to a study in the August 5 issue of JAMA, a theme issue on violence and human rights.

Regional nerve block anesthesia improve recovery, outcomes

When planning for surgery, patients too often don't consider the kind of anesthesia they will receive. In fact, the choice of anesthesia can improve recovery, even outcomes.

Workplace meditation and yoga lowers stress

Twenty minutes per day of guided workplace meditation and yoga combined with six weekly group sessions can lower feelings of stress by more than 10 percent and improve sleep quality in sedentary office employees, a pilot study suggests.

Silenced genes provide warning sign of blood cancer

In many types of cancer, parts of the genetic material of tumor cells are switched off by chemical labels called methyl groups. This kind of methyl labeling ranges among the epigenetic changes that do not change the sequence of DNA building blocks. Such labels are found particularly often in genes which act as important inhibitors of pathogenic cell growth.

Exercise for the brain may slow dementia

People who engage in activities that exercise the brain, such as reading, writing, and playing card games, may delay the rapid memory decline that occurs if they later develop dementia, according to a study published in the August 4, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology.

High levels of glutamate in brain linked to depression, low cognitive function

Researchers at the Joslin Diabetes Center and several other institutions have for the first time linked high levels of glutamate – a neurotransmitter in the brain produced from glucose – in people with type 1 diabetes to symptoms of depression and lower levels of cognitive performance. The findings may lead to a better understanding of the underlying mechanisms of these conditions in people with diabetes.

Women and minorities under-represented in trials

Enrollment demographics published in many U.S. vascular surgery randomized control trials (RCTs) under-represent women as well as race or ethnic minorities, according to a new study published in the Society for Vascular Surgery’s August 2009 issue of the Journal of Vascular Surgery.

New method selectively kills metastatic melanoma

An international team of researchers has identified a new method for selectively killing metastatic melanoma cells, which may lead to new areas for drug development in melanoma – a cancer that is highly resistant to current treatment strategies.

Carbon nanosensor sniffs out kidney disease

A carbon nanosensor “electronic nose” - first developed by Technion-Israel Institute of Technology researchers to detect cancer from breath samples - has been modified to identify chronic renal failure (CRF).

Heavy drinkers have much higher risk of developing cancer

Heavy drinkers of beer and spirits face a much higher risk of developing cancer than the population at large, says a group of Montreal epidemiologists and cancer researchers.

Links between major depression and coronary artery disease studied

Major depression and coronary artery disease are only modestly related throughout an individual’s lifetime, but studying how the two interact over time and in twin pairs paints a more complex picture of the associations between the conditions, according to a report in the August issue of Archives of General Psychiatry. For example, the association between coronary artery disease onset and major depression risk is much stronger over time than vice versa.

Discovery of novel tumor suppressor

La Jolla Institute for Allergy & Immunology researchers studying an enzyme believed to play a role in allergy onset, instead have discovered its previously unknown role as a tumor suppressor that may be important in myeloproliferative diseases and some types of lymphoma and leukemia.

Stem cell technology innovation could reduce the number of animal experiments

Researchers from the University of Bath are embarking on a project to use stem cell technology that could reduce the number of animal experiments used to study conditions such as motor neurone disease.

Elevated cholesterol levels in midlife raises risk of late-life dementia

Elevated cholesterol levels in midlife - even levels considered only borderline elevated - significantly increase the risk of Alzheimer's disease and vascular dementia later in life, according to a new study by researchers at Kaiser Permanente's Division of Research and the University of Kuopio in Finland. The study appears in the journal Dementia & Geriatric Cognitive Disorders.
