Current use of glucocorticoids linked to atrial fibrillation, flutter Posted: 14 Oct 2009 05:00 PM PDT The current, but not previous, use of glucocorticoids is associated with an increased risk for atrial fibrillation or flutter, results of a case–control study suggest.

Smoking does not fully explain COPD link to lung cancer Posted: 14 Oct 2009 05:00 PM PDT The increased risk for lung cancer among patients with chronic obstructive pulmonary disease is not wholly attributable to smoking, study results suggest.

Winter ICU swine admissions in Australia, New Zealand analyzed Posted: 14 Oct 2009 05:00 PM PDT Results of a study conducted in Australia and New Zealand show that 722 patients infected with the H1N1 influenza were admitted to intensive care units during the 2009 winter flu season, and these patients occupied up to nearly 20% of ICU beds when the epidemic was at its peak.

Motivation mediates link between cognition and outcome in schizophrenia Posted: 14 Oct 2009 05:00 PM PDT The relationship between neurocognition, social cognition, and functional outcome in schizophrenia appears to be mediated by motivation, say US scientists who suggest the findings may help to improve social integration for patients.

Melatonin light super-sensitivity identified in bipolar I disorder Posted: 14 Oct 2009 05:00 PM PDT Patients with bipolar I disorder have melatonin super-sensitivity to light compared with healthy individuals, which may serve as an endophenotypic marker for the condition, conclude Australian researchers.

Mastectomy not overused for breast cancer treatment Posted: 13 Oct 2009 05:00 PM PDT A US study has shown that most surgeons appropriately recommend breast conserving surgery, as opposed to mastectomy, for patients with early-stage breast cancer.

MRI effective for detecting evasive anterior prostate cancer Posted: 13 Oct 2009 05:00 PM PDT Men with persistently elevated prostate-specific antigen levels but negative or small volume biopsy results should undergo magnetic resonance imaging for hard-to-detect tumors, report researchers.

Many prostate cancer patients receiving hormone therapy die of other causes Posted: 13 Oct 2009 05:00 PM PDT A large number of prostate cancer patients undergoing androgen deprivation therapy as initial treatment die from non-cancer causes, according to a UK study.

Low LDL cholesterol, albuminuria linked with elevated cancer risk in Type 2 diabetics Posted: 13 Oct 2009 05:00 PM PDT Low levels of low-density lipoprotein cholesterol and the presence of albuminuria are associated with an increased risk for cancer in Type 2 diabetes, report Chinese researchers.

Ad36 virus associated with obesity and hypertension independent of IR Posted: 13 Oct 2009 05:00 PM PDT Seropositivity for the adenovirus Ad36 is associated with obesity and essential hypertension independently of insulin resistance, show study results.

High HDL cholesterol may not be beneficial for older women Posted: 13 Oct 2009 05:00 PM PDT One third of postmenopausal, middle-aged women have subclinical atherosclerosis despite having normal-to-high high-density lipoprotein cholesterol levels and a Framingham risk score below 7%, report researchers.

Novel diabetes treatment albiglutide improves glucose control and promotes weight loss Posted: 13 Oct 2009 05:00 PM PDT A phase II study of the glucagon-like peptide 1 receptor agonist albiglutide demonstrates significant reductions in blood glucose levels and weight loss with all dosing regimens, report researchers in the journal Diabetes Care.

Low LDL cholesterol, albuminuria linked with elevated cancer risk in Type 2 diabetics Posted: 13 Oct 2009 05:00 PM PDT Low levels of low-density lipoprotein cholesterol and the presence of albuminuria are associated with an increased risk for cancer in Type 2 diabetes, report Chinese researchers.

Pre-op natriuretic peptides predict short-term noncardiac surgery outcome Posted: 13 Oct 2009 05:00 PM PDT An elevated pre-operative brain natriuretic peptide or N-terminal pro-BNP level is a powerful predictor of cardiovascular events in the first 30 days after noncardiac surgery, conclude researchers.

Major depression, microvascular dysfunction may share genetic basis Posted: 13 Oct 2009 05:00 PM PDT Findings of a twin study suggest that major depressive disorder and microvascular dysfunction are linked to each other by a shared genetic pathway.

Current glucocorticoid use linked to atrial fibrillation, flutter Posted: 12 Oct 2009 05:00 PM PDT Current glucocorticoid users are almost twice as likely to develop atrial fibrillation or flutter as people who have never used the drugs, results of a case–control study suggest.
