Thromboembolism May Recur With Residual Vein Obstruction
THURSDAY, March 24 (HealthDay News) -- In patients with provoked or unprovoked deep vein thrombosis (DVT), residual vein obstruction (RVO) is associated with a slight increase in the risk of recurrent venous thromboembolism (VTE) but does not seem to predict recurrent VTE in patients with unprovoked DVT following discontinuation of anticoagulation therapy, according to a meta-analysis published online March 7 in the Journal of Thrombosis and Haemostasis.
Reduced Hours for Trainees Has Had Little Effect in U.S.

Low-Dose Imaging Effective for Ruling Out CAD
THURSDAY, March 17 (HealthDay News) -- Low-dose coronary computed tomography (CT) appears as sensitive as catheter-based angiography and may provide a non-invasive alternative to the latter for ruling out coronary artery disease (CAD) in symptomatic patients, according to a meta-analysis published in the March 15 issue of the Annals of Internal Medicine.
Professional Values of U.S. and U.K. Doctors Examined

Short Nurse Staffing Linked to Higher Patient Mortality
WEDNESDAY, March 16 (HealthDay News) -- Patient mortality appears to be higher when nurse staffing falls eight or more hours below target level and during nursing shifts when patient turnover is high, according to research published in the March 17 issue of the New England Journal of Medicine.

Lower Survival Associated With GI Brain Metastasis
FRIDAY, March 11 (HealthDay News) -- Surgical resection and whole brain radiation therapy of gastrointestinal (GI) brain metastases is associated with prolonged survival and improved quality of life, but survival is still lower compared to metastases arising from other tumors, according to a review published online Feb. 11 in Cancer.
Interstitial Lung Abnormalities Tied to Reduced Lung Capacity
WEDNESDAY, March 9 (HealthDay News) -- Interstitial lung abnormalities on high-resolution computed tomographic (HRCT) scans appear to be associated with reduced total lung capacity and a lesser amount of emphysema among smokers, according to a study published in the March 10 issue of the New England Journal of Medicine.
HealthGrades Finds Rates of Patient Safety Events Vary
WEDNESDAY, March 9 (HealthDay News) -- Patients treated at hospitals rated with a HealthGrades Patient Safety Excellence Award have, on average, a 46 percent lower risk of experiencing a patient safety incident compared to those treated at the lowest-ranked hospitals, according to the eighth annual HealthGrades Patient Safety in American Hospitals Study published online March 9.
Ethnic Differences Seen in Academic Measures for U.K. Docs
WEDNESDAY, March 9 (HealthDay News) -- United Kingdom-trained physicians and medical students with ethnic minority backgrounds tend to underperform academically compared to their white peers, according to a meta-analysis published online March 8 in BMJ.
Pharmacological Meta-Analyses Rarely Report Disclosures

Fatty Liver Independently Linked to Type 2 Diabetes
TUESDAY, March 8 (HealthDay News) -- Ultrasound-diagnosed fatty liver is independently associated with an increased risk of type 2 diabetes mellitus (T2DM), according to a study published online Jan. 20 in the Journal of Clinical Endocrinology & Metabolism.
Cancer Patients Willing to Undergo Pre-Trial Testing
