Tips to avoid heat stroke

The first sign of dangerous heat stroke can be just that – no sweat. As the temperature rises, your body’s natural cooling mechanism, sweat (or more kindly, perspiration), evaporates and helps to cool your body. But on those hot, humid cut-the-air-with-a knife days, evaporation is slowed and your body may not be able to keep itself cool.

New insights into peripheral artery disease

Walking is a painful experience for many of the eight million Americans who suffer lower extremity peripheral arterial disease, or PAD. The condition, which is associated with aging and involves progressive functional decline, can cause heaviness, tightness, cramping or sharp pain in the calf muscle. Symptoms typically disappear with rest and return when walking resumes.

Discovery of novel function of hormone found in gut that may lower glucose levels in diabetes

A research team led by Dr. Tony Lam at the Toronto General Research Institute and the University of Toronto discovered a novel function of a hormone found in the gut that might potentially lower glucose levels in diabetes.

Less is more when it comes to blood transfusions

A new study suggests that blood transfusions for hospitalized cardiac patients should be a last resort because they double the risk of infection and increase by four times the risk of death.

Epigenetic alterations may serve as markers for chronic leukemia

A new study shows that certain genes are turned off early, before clinical signs of the disease appear, in the development of chronic leukemia.

Social stress linked to visceral fat, atherosclerosis

A new study done by researchers at Wake Forest University School of Medicine shows that social stress could be an important precursor to heart disease by causing the body to deposit more fat in the abdominal cavity, speeding the harmful buildup of plaque in blood vessels, a stepping stone to the number one cause of death in the world.

New understanding on Gleevec's limitations

University of Michigan researchers have developed an animal model that provides strong evidence why imatinib, marketed as Gleevec, helps patients with chronic myeloid leukemia survive longer, but does not keep the disease from returning if treatment ends.

Cooling unconscious cardiac arrest survivors increases survival, cost effective

Cooling unconscious cardiac arrest survivors can increase survival and has a cost effectiveness comparable to other widely accepted treatments in modern health care, researchers report in Circulation: Cardiovascular Quality and Outcomes.

Depression and inflammation linked to rheumatoid arthritis pain

Researchers at Nagoya City University and Nagoya University Graduate Schools of Medicine in Japan studied the interrelationship between levels of depression symptoms, C-reactive protein (CRP) level, and pain, confirming a significant positive association between depressive symptoms and CRP level in RA.

Many countries still selling consumer paints with dangerous levels of lead

Although lead content in paint has been restricted in the United States since 1978, University of Cincinnati (UC) environmental health researchers say in major countries from three continents there is still widespread failure to acknowledge its danger and companies continue to sell consumer paints that contain dangerous levels of lead.

Emergency physicians should trust their judgment on chest pain symptoms

Their research suggests that emergency physicians should counsel with other physicians against discharge when they feel strongly about a patient for whom there is no compelling data, other than our evaluation and judgment, Chandra said.

Jefferson names endowed Professorship in transplant surgery

Cataldo Doria, M.D., Ph.D., F.A.C.S., director, Division of Transplant Surgery, in the Department of Surgery at Thomas Jefferson University Hospital, has been named the Nicoletti Family Professor of Transplant Surgery. This endowed professorship is a generous gift of Robert and Beatrice Nicoletti and their family. The family cited the care they received at Jefferson when Robert received a new kidney donated by his own daughter, as the reason for their donation.

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.

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.

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).

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.

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.

Divers who hold breath for several minutes elevate a marker for brain damage

Divers who held their breath for several minutes had elevated levels of a protein that can signal brain damage, according to a new study from the Journal of Applied Physiology. However, the appearance of the protein, S100B, was transient and leaves open the question of whether lengthy apnea (breath-holding) can damage the brain over the long term.

Will emphasis on prevention bring health costs down?

If there is one thing that both parties can agree on in the health overhaul debate, it’s the need to build a health system that promotes prevention rather than just manages disease.
