Global survey highlights need for cancer prevention campaigns to correct misbeliefs

Tweet

GENEVA, Switzerland – Many people hold mistaken beliefs about what causes cancer, tending to inflate the threat from environmental factors that have relatively little impact while minimizing the hazards of behaviours well established as cancer risk factors, according to the first global survey on the topic.

The survey, conducted by Roy Morgan Research and Gallup International on behalf of the International Union of Against Cancer (UICC), identified key areas where misconceptions could be addressed and where lives could be saved.

Novel Trial Design Aims to Speed Drug Development

Researchers propose a novel multi-arm trial design that can test several therapies simultaneously and could speed drug development in cancer.

Scientists have gained important insights into the biological underpinnings of cancer, but this knowledge has not led to a jump in the number of therapies approved for clinical use. One possible reason for the slower than expected progress is the time required for clinical testing with current trial designs.

Angiotensin inhibitors and receptor blockers linked to lower risk of nonmelanoma skin cancer

Findings challenge common practice regarding glucose control for critically ill patients

Tweet

An analysis of randomized trials indicates that for critically ill adults, tight glucose control is not associated with a significantly reduced risk of death in the hospital, but is associated with an increased risk of hypoglycemia, calling into question the recommendation by many professional societies for tight glucose control for these patients, according to an article in the August 27 issue of JAMA.

High levels of uric acid may be associated with high blood pressure

Tweet

Reducing levels of uric acid in blood lowered blood pressure to normal in most teens in a study designed to investigate a possible link between blood pressure and the chemical, a waste product of the body's normal metabolism, said researchers at Baylor College of Medicine in a report that appears in the current issue of the Journal of the American Medical Association.

Report suggests allopurinol may lower blood pressure in teens with hypertension

Tweet

The drug allopurinol, which lowers uric acid levels, appears to reduce blood pressure in adolescents with newly diagnosed hypertension, according to a preliminary report in the August 27 issue of JAMA.
