Insurance can help farmers to survive dry periods but it can also result in the long term in overgrazing and therefore threaten their existence if insurance companies pay out in periods of moderate drought and farmers change their management strategies as a result, according to the world's first study on the ecological effects of rain-index insurance.

CHICAGO – A survey of patients receiving treatment in a teaching facility found that patients prefer to be informed of trainee participation in their care, and consent rates appear to vary based on scenarios describing increased levels of resident participation, according to a report published Online First by Archives of Surgery, one of the JAMA/Archives journals.

Despite improvements in treating heart attack patients needing emergency artery-opening procedures, delays still occur, particularly in transferring patients to hospitals that can perform the procedure, according to a study in Circulation: Journal of the American Heart Association.

Fast response is critical for ST-segment elevation myocardial infarction (STEMI) patients. This severe heart attack is caused by a complete blockage of blood supply to the heart. More than 250,000 people suffer a STEMI each year.

The biotech industry boosted farming across the globe to the tune of almost $65 billion during the period 1996 to 2009, according to the latest analysis published in the International Journal of Biotechnology. $65 billion is the increase in net farm income, the farm level benefit after paying for the seed and its biotech traits.

More species could be saved from extinction under climate change thanks to a new model scientists have developed to guide allocation of conservation funding.

An international team led by Dr Brendan Wintle of the University of Melbourne and the ARC Centre of Excellence for Environmental Decisions is the first to develop a decision-support model that incorporates both ecological and economic information to guide conservation investment in the face of climate change.

In more than 70 per cent of legal disputes over informed consent, patients allege the doctor failed to properly explain the risks of complications, a University of Melbourne study published in the latest Medical Journal of Australia has found.

Bethesda, Md. (Sept. 19, 2011) – Roughly 5 million people in the United States live with heart failure, a condition in which the heart is unable to pump blood around the body effectively. The causes and types of heart failure vary greatly, and treatment must be tailored to each patient. In some cases, doctors will prescribe a class of diuretic drugs called aldosterone antagonists. However, these diuretics may cause dangerously high levels of potassium in the blood (hyperkalemia) of certain patients, putting them at risk for sudden cardiac death.

Researchers from Taiwan have confirmed a bidirectional relation between schizophrenia and epilepsy. The study published today in Epilepsia, a journal of the International League Against Epilepsy (ILAE), reports that patients with epilepsy were nearly 8 times more likely to develop schizophrenia and those with schizophrenia were close to 6 times more likely to develop epilepsy.
