Higher levels of blood phosphate may be a previously unidentified and modifiable cardiovascular risk factor

Healthy adults with higher levels of phosphate in the blood are more likely to have increased levels of calcium in the coronary arteries-a key indicator of atherosclerosis and future cardiovascular disease risk, reports a study in the February 2009 issue of the Journal of the American Society of Nephrology (JASN).

No clear evidence that depression screening improves cardiovascular patients' health

Results of a new study call into question recent clinical guidelines issued by leading cardiovascular groups, including the American Heart Association, which recommend patients with cardiovascular disease be screened for signs of depression and treated accordingly.

Healthy life expectancy in Europe

Although life expectancy is constantly growing in the countries of the EU, living longer isn't always the same as living well, and knowing to what age someone will live in good health remains a different question altogether.

Potential new therapeutic targets for rejuvenating the aged immune system

In the November 15th issue of G&D, Dr. Kenneth Dorshkind and colleagues at the David Geffen School of Medicine (UCLA) have identified two genes - p16(Ink4a) and Arf - that sensitize lymphoid progenitor cells to the effects of aging, and confer resistance to leukemogenesis.

Gender found to be play important role as a prognostic factor in people diagnosed with lung cancer

Even though some combinations of gender, race and/or marital status can factor into the overall survival of nonoperative non-small cell lung cancer patients, gender is the most significant factor impacting overall survival, according to a study presented at the 2008 Chicago Multidisciplinary Symposium in Thoracic Oncology, sponsored by ASTRO, ASCO, IASLC and the University of Chicago.

Drug-related preference in cocaine addiction extends to images

When given a choice between viewing pictures of cocaine and a variety of other images, cocaine addicted individuals, as compared to healthy, non-addicted research subjects, show a clear preference for the drug-related images.

Doctors' questions about end-of-life legalities may result in patient pain

When treatment options dwindle or are exhausted, terminally ill-patients often opt for pain management and comfort over life-extending therapies.

Difluoromethylornithine may affect Barrett's esophagus

"While there was a suggestion that difluoromethylornithine (DFMO) may influence the extent of Barrett's dysplasia, this finding is very preliminary and further study of this agent in a larger number of patients is needed," said Frank A. Sinicrope, M.D., professor of medicine and oncology at the Mayo Clinic, Rochester, MN.

Cigarette smoke may reshape the left ventricle

Prolonged exposure to cigarette smoke can increase levels of the stress hormone norepinephrine and enzymes in the heart that have the potential to reshape the left ventricle, according to new research at the University of Illinois at Chicago.

Traditional chemotherapy agents with targeted therapies improves survival in advance-stage lung cancer

The combination of traditional chemotherapy agents with targeted therapies called monoclonal antibodies showed no safety concerns and improved survival in patients with advanced non-small cell lung cancer according to a study presented at the 2008 Chicago Multidisciplinary Symposium in Thoracic Oncology, sponsored by ASTRO, ASCO, IASLC and the University of Chicago.

Breast and prostate cancer treatment may result in bone loss

A new cross-Canada study has found that breast and prostate cancer treatment can foster bone loss.

Calcium may only protect against colorectal cancer in presence of magnesium

High magnesium intake has been associated with low risk of colorectal cancer. Americans have similar average magnesium intake as East Asian populations. If that were all that were involved, observers might expect both groups to have similar risk for colorectal cancer.

Alzheimer's gene apolipoprotein E4 slows export of amyloid-beta

The only known genetic risk factor for Alzheimer's disease slows down the brain's ability to export a toxic protein known as amyloid-beta that is central to the damage the disease causes, scientists have found.

Advanced lung cancer patients see improved, progression-free survival

Patients with advanced non-small cell lung cancer whose disease has progressed following chemotherapy have a higher rate of tumor shrinkage and a longer interval before cancer progression when bevacizumab is added to standard second-line erlotinib therapy, according to a study presented at the 2008 Chicago Multidisciplinary Symposium in Thoracic Oncology, sponsored by ASTRO, ASCO, IASLC and the University of Chicago.

$8.4 million research grant to improve patient safety in Australia

A major cross institutional research collaboration aimed at reducing the number of patients harmed in Australia has received $8.4 million in funding in the latest round of National Health and Medical Research Council (NHMRC) program grants.

Hope for treating relapse to methamphetamine abuse

"Reinstatement of drug-seeking behavior after an extended period of abstinence is the number-one cause of drug-addiction relapse," said Brookhaven neuroanatomist Stephen Dewey, who led the research team. "This animal study suggests that vigabatrin could potentially prevent human methamphetamine addicts from relapsing."

Breakthrough in cell-type analysis offers new ways to study development and disease

Like skilled assassins, many diseases seem to know exactly what types of cells to attack. While decimating one cadre of cells, diseases will inexplicably spare a seemingly identical group of neighbors. What makes cells vulnerable or not depends largely on the kinds and amounts of proteins they produce - their 'translational profile,' in the lingo of molecular biology. For this reason, scientists have struggled to parse the subtle molecular differences among the hundreds of specialized cell types that are tangled together in tissues like the brain.

Widespread public support for large genetic study

Four in five Americans support the idea of a nationwide study to investigate the interactions of genes, environment and lifestyle, and three in five say they would be willing to take part in such a study, according to a survey released today.

Sex differences narrow in death after heart attack

In recent years, women, particularly younger women, experienced larger improvements in hospital mortality after myocardial infarction than men, according to a new study.
