Advanced care planning improves end-of-life care

Advance care planning for older adults results in improved quality of care at the end of life, with less in-hospital death and the increased use of hospice services, the results of a study indicate.

Nitric oxide shuts down brain's repair mechanisms

Nitric oxide, a gaseous molecule produced in the brain, can damage neurons. When the brain produces too much nitric oxide, it contributes to the severity and progression of stroke and neurodegenerative diseases such as Alzheimer's. Researchers at Sanford-Burnham Medical Research Institute recently discovered that nitric oxide not only damages neurons, it also shuts down the brain's repair mechanisms.

Immune system can use melanoma's own proteins to kill off cancer cells

Though a small group of proteins, the family called Ras controls a large number of cellular functions, including cell growth, differentiation, and survival. And because the protein has a hand in cellular division, mutated Ras, which can be detected in one-third of all tumors, contributes to many human cancers by allowing for the rapid growth of diseased cells.

Triggers linked to migraines with aura remain nebulous

Only a small fraction of patients who suffer from migraine with aura experience an attack when they are exposed to self-reported natural triggers in an experimental setting, research shows.

Reduced nicotine metabolism is associated with a greater number of cigarettes smoked per day and increased levels of dependence in adolescent smokers, researchers report.

Poor diet provides clue to metabolic abnormalities in schizophrenia

Patients with schizophrenia commonly have a poor diet, say UK researchers who believe this may partly account for the increased incidence of metabolic abnormalities in these patients.

Hope against dangerous form of acute lymphoblastic leukemia

After an intensive three-year hunt through the genome, medical researchers have pinpointed mutations that leads to drug resistance and relapse in the most common type of childhood cancer-the first time anyone has linked the disease's reemergence to specific genetic anomalies.

Sneezing and wheezing are common among people living close to the equator

Those living near the equator may find themselves sneezing and wheezing more than usual. And the reason may not be due to increasing pollen counts.

Scientists visualise molecular changes in Bax protein that force cells to die

Scientists at the Walter and Eliza Hall Institute have for the first time visualised the molecular changes in a critical cell death protein that force cells to die.

Study shows how placental circulation can influence malarial parasite behavior and infection

Malaria in pregnancy causes a range of adverse effects, including abortions, stillbirths, premature delivery and low infant birth weight. Many of these effects are thought to derive from a placental inflammatory response resulting from interaction of infected red blood cells with the placental tissue.

Researchers create high-resolution map of gene regulatory elements in the brain

Future research into the underlying causes of neurological disorders such as autism, epilepsy and schizophrenia, should greatly benefit from a first-of-its-kind atlas of gene-enhancers in the cerebrum (telencephalon).

New drug to prevent early stages of Alzheimer's could enter clinical trials soon

A new drug to prevent the early stages of Alzheimer's disease could enter clinical trials in a few years' time according to scientists.

Inadequate health literacy among Latinos linked with poor understanding of antibiotic use

In the first study of its kind, researchers at the Columbia University School of Nursing have established that poor health literacy among Latino parents is associated with a poor understanding of the proper use antibiotics, particularly for upper respiratory infections (URIs), which can lead to an increase in antimicrobial resistance.

Scientists uncover key mechanism that links obesity and diabetes with cancer

Sugars are needed to provide us with energy and in moderate amounts contribute to our well-being. Sustained high levels of sugars, as is found in diabetics, damages our cells and now is shown that can also increase our chance to get cancer: The dose makes the poison as Paracelsus said.

State roundup: Texas lawmakers ready health budget

Texas budget writers got a briefing on the state's health care programs Wednesday, and many of the biggest questions focused on how the state can reduce fraud and what to do about ever-increasing health care costs.

Study investigates R1441G mutation of Parkinson's disease

A team from the UPV/EHU-University of the Basque Country came across a mutation of the LRRK2 gene in 2004, which is particularly prevalent among the population of Gipuzkoa. It is the R1441G mutation and is known as the Basque mutation.

HIV infection rate in MSM in England and Wales remains unchanged despite improved prevention measures

The rate of new HIV infections among men who have sex with men (MSM) in England and Wales has remained unchanged over the past decade despite an almost four-fold increase in HIV testing, rising treatment coverage, and a 20% shortening of time-to-diagnosis, according to new research published Online First in The Lancet Infectious Diseases.

Possible link between outdoor food ads and a tendency to pack on pounds

Past studies have suggested a relationship between neighborhood characteristics and obesity, as well as a connection between obesity and advertisements on television and in magazines.

Study expands and deepens biological and genetic links between CVD and schizophrenia

A new study, to be published in the Feb. 7, 2013 issue of the American Journal of Human Genetics, expands and deepens the biological and genetic links between cardiovascular disease and schizophrenia. Cardiovascular disease (CVD) is the leading cause of premature death among schizophrenia patients, who die from heart and blood vessel disorders at a rate double that of persons without the mental disorder.

Study evaluates link between sedentary time and death among breast cancer survivors

Spending a lot of time watching television after breast cancer diagnosis is not linked to death in these breast cancer survivors. It appears that after accounting for self-reported physical activity levels after diagnosis, sedentary behavior was not an independent risk factor for death.
