Warfarin sensitivity falls after valve surgery Posted: 25 Feb 2010 04:00 PM PST Research indicates that a decrease in sensitivity to warfarin in the months after heart valve surgery may place patients at risk for receiving subtherapeutic anticoagulant therapy.

High trans fat consumption increases risk for ischemic stroke Posted: 25 Feb 2010 04:00 PM PST Postmenopausal women who consume high amounts of fat, in particular trans fat, have an increased risk for ischemic stroke, report US researchers.

Far erythemogenic NB-UVB dose effective for plaque-type psoriasis Posted: 25 Feb 2010 04:00 PM PST Far erythemogenic dose of narrow-band ultraviolet B phototherapy appears to be as effective as near and suberythemogenic doses for plaque-type psoriasis, say researchers.

PCA3 does not predict short-term biopsy progression Posted: 25 Feb 2010 04:00 PM PST Short-term biopsy progression in men under active surveillance cannot be predicted by the level of PCA3 in their urine samples, research suggests.

Late rectal toxicity after prostate RT depends on dose distribution Posted: 25 Feb 2010 04:00 PM PST The incidence of late rectal toxicity after prostate radiotherapy could be reduced by considering the entire dose distribution to the rectum, researchers report.

PCA3 does not predict short-term biopsy progression Posted: 25 Feb 2010 04:00 PM PST Short-term biopsy progression in men under active surveillance cannot be predicted by the level of PCA3 in their urine samples, research suggests.

Late rectal toxicity after prostate RT depends on dose distribution Posted: 25 Feb 2010 04:00 PM PST The incidence of late rectal toxicity after prostate radiotherapy could be reduced by considering the entire dose distribution to the rectum, researchers report.

Contralateral prophylactic mastectomy improves survival for certain patients Posted: 25 Feb 2010 04:00 PM PST Contralateral prophylactic mastectomy may only offer a survival benefit to younger women with early-stage estrogen receptor-negative breast cancer, US researchers have found.

High trans fat consumption increases risk for ischemic stroke Posted: 25 Feb 2010 04:00 PM PST Postmenopausal women who consume high amounts of fat, in particular trans fat, have an increased risk for ischemic stroke, report US researchers.

Pericardial fat linked to carotid stiffness Posted: 25 Feb 2010 04:00 PM PST Pericardial fat is associated with carotid artery stiffness independently of traditional risk factors for cardiovascular disease and obesity, US researchers report.

Drug-eluting stents, CABG ‘equivalent’ in diabetic multivessel disease Posted: 25 Feb 2010 04:00 PM PST Drug-eluting stents and coronary artery bypass graft surgery are equivalent for preventing major vascular events in patients with diabetes mellitus and multivessel disease, analysis of registry data suggests.

Diabetics have more vulnerable atherosclerotic plaque than nondiabetics Posted: 25 Feb 2010 04:00 PM PST Study results show that patients with atherosclerosis and diabetes have a larger proportion of intravascular ultrasound-derived thin cap fibroatheroma, which is more vulnerable to rupture, than atherosclerotic individuals without diabetes.

Angiographic factors strongly predict ischemic outcomes in NSTE-ACS Posted: 25 Feb 2010 04:00 PM PST Angiographic parameters are more powerfully predictive of ischemic outcomes than traditional clinical parameters in non-ST-segment elevation acute coronary syndrome patients treated medically, a substudy of ACUITY indicates.

Remote ischemic preconditioning improves myocardial salvage after PCI Posted: 25 Feb 2010 04:00 PM PST Researchers report that remote ischemic preconditioning, by the induction of intermittent upper-arm ischemia, before primary percutaneous coronary intervention reduces reperfusion injury and thereby increases myocardial salvage in patients with evolving myocardial infarction.

Contralateral prophylactic mastectomy improves survival for certain patients Posted: 25 Feb 2010 04:00 PM PST Contralateral prophylactic mastectomy may only offer a survival benefit to younger women with early-stage estrogen receptor-negative breast cancer, US researchers have found.
