Researchers find animal with ability to survive climate change

Queen's researchers have found that the main source of food for many fish - including cod - in the North Atlantic appears to adapt in order to survive climate change.

Billions of Calanus finmarchicus, a plankton species, which are just a few millimetres in size, live in the waters of the North Atlantic where the research was carried out.

Trachoma in Ayod county, Sudan: 1 of the most severe burdens documented

The burden of trachoma in Ayod county, one of the most severe ever documented, is a threat to public health in Southern Sudan, according to a recent survey conducted in Jonglei state. These results, published September 24th in the open-access journal PLoS Neglected Tropical Diseases, were uncovered by experts at The Carter Center and University of Cambridge, and health officials from the government of Southern Sudan. The research determines the extent of the problem and resources needed to eliminate blinding trachoma from the county.

Isoflavone dietary supplement improves the functioning of the arteries in stroke patients

A dietary supplement containing isoflavone – a chemical found in soybeans, chickpeas, legumes and clovers – can improve artery function in stroke patients according to new research published online in Europe's leading cardiology journal, the European Heart Journal [1] today (Wednesday 24 September).

Plant antioxidant may protect against radiation exposure

PITTSBURGH, Sept. 23 – Resveratrol, the natural antioxidant commonly found in red wine and many plants, may offer protection against radiation exposure, according to a study by the University of Pittsburgh School of Medicine. When altered with acetyl, resveratrol administered before radiation exposure proved to protect cells from radiation in mouse models. The results of the research will be presented during the American Society for Therapeutic Radiology and Oncology's (ASTRO) 50th Annual Meeting in Boston.

New model predicts relapse in early breast cancer patients following endocrine therapy

Researchers have developed and validated a model that predicts relapse in women with stage 2 or 3 breast cancer who have been treated with endocrine therapy prior to surgical removal of the tumor, according to a study published online September 23 in the Journal of the National Cancer Institute. The preoperative endocrine prognostic index (PEPI) may help identify women who can safely avoid chemotherapy and those women at high risk of relapse who should be considered for aggressive therapy.

Observational study suggests hormone therapy safe for postmenopausal BRCA mutation carriers

The use of hormone therapy was associated with a reduced risk of breast cancer in postmenopausal women who carry BRCA mutations, according to a case-control study published online September 23 in the Journal of the National Cancer Institute.

Popular COPD treatment increases risk for cardiac events, cardiac death

WINSTON-SALEM, N.C. – New research out of Wake Forest University School of Medicine shows that use of the most commonly prescribed once-a-day treatment for chronic obstructive pulmonary disease (COPD) for longer than one month increases the risk of cardiovascular death, heart attack or stroke by more than 50 percent.

Study finds wide variability in survival after emergency treatment for cardiac arrest

An analysis of emergency medical services–treated cardiac arrest outcomes in 10 areas in North America finds a five-fold difference in survival rates, according to a study in the September 24 issue of JAMA.

Termination-of-resuscitation rules helps ID cardiac arrest patients with small chance of survival

Researchers have validated criteria that are used to identify patients with out-of-hospital cardiac arrest who have little or no chance of survival after resuscitation, according to a study in the September 24 issue of JAMA.

Common COPD medications linked with increased risk of CV death, heart attack

The use of inhaled anticholinergic agents (medications that help reduce bronchospasm) by patients with chronic obstructive pulmonary disease (COPD) is associated with a significantly increased risk of heart attack, stroke of cardiovascular death, according to a meta-analysis of randomized trials published in the September 24 issue of JAMA.

Saving lives more efficiently: Cardiac arrest study may help EMS and ERs

ANN ARBOR, Mich. — When someone's heart suddenly stops beating – a condition called cardiac arrest -- there's a lot that bystanders and ambulance crews can do to get it started again. But if the victim doesn't respond, when should such efforts stop?

And when should emergency crews rapidly transport a patient to a hospital with lights and sirens on, potentially endangering the lives of paramedics and other motorists and pedestrians — even though the care provided by the emergency crew is the same as what can be provided in the emergency department?

Study findings help EMS respond to cardiac arrest emergencies more safely and efficiently

When cardiac arrest patients cannot successfully be resuscitated by emergency medical services in the field, lifesaving attempts to race them to a nearby hospital via ambulance often prove to be futile. In additions, the effort potentially increases danger to other drivers, pedestrians and the EMS professionals themselves, according to findings reported in the Sept. 24, 2008 issue of the Journal of the American Medical Association.

New predictive tool can help determine treatment of breast cancer patients

A new predictive measurement, called a PEPI score, could bring good news to many women diagnosed with early stage breast cancer — a low PEPI (preoperative endocrine prognostic index) score could show that they have little risk of relapse and can safely avoid chemotherapy after surgery.

For others, a high PEPI score could warn that the risk of relapse after breast surgery is large and indicates that careful follow-up and aggressive therapy may be needed, say researchers at Washington University School of Medicine in St. Louis and collaborating institutions in Europe.

Bladder cancer detected via amplified gene in cells found in urine

HOUSTON - Counting the copies of a specific gene in cells gathered from a urine sample may provide a simple, noninvasive way to detect bladder cancer, a team led by researchers at The University of Texas M. D. Anderson Cancer Center reports in the Journal of the National Cancer Institute.

When the telltale gene, Aurora kinase A, is numerous and overexpressed in urothelial cells, errors during cell division follow, the team also found. The new cells have too few or too many chromosomes, instead of the normal pairs of 23 chromosomes.

Lack of large-scale experiments slows progress of environmental restoration

Madison, Wisc. - September 23, 2008 – A new study finds that environmental restoration research using large experimental tests has been limited. The study, published in Restoration Ecology, maintains that for restoration to progress as a science and a practice, more research should be done on whole ecosystems with large experiments.
