Aims:To assess the risk of death after the occurrence of different types of non-fatal events in patients with atrial fibrillation (AF). Antithrombotic therapies in AF have primarily focused on stroke prevention and bleeding. However, strokes and bleeds differ in severity, and the level of severity may differently impact mortality.Methods and results: We analysed the risk of subsequent mortality after the occurrence of non-fatal vascular and bleeding events in the Atrial Fibrillation Clopidogrel Trial with Irbesartan for Prevention of Vascular Events (ACTIVE)-W trial. In the 3371 patients randomized to vitamin K antagonists and the 3335 patients randomized to clopidogrel plus aspirin in ACTIVE-W, the hazard ratio (HR) and 95 confidence intervals (95 CIs) for subsequent death associated with the occurrence of non-fatal stroke was 5.58 (95 CI 3.84-8.10, P < 0.0001). Both ischaemic (HR 5.29, 95 CI 3.53-7.93, P < 0.0001) and haemorrhagic strokes (HR 7.38, 95 CI 2.74-19.9, P < 0.0001) increased mortality, but transient ischaemic attacks did not. Disabling strokes (Rankin's score ≥3) increased mortality (HR 9.54; 95 CI 6.42-14.2, P< 0.0001), but non-disabling strokes did not. Severe bleeding increased mortality (HR 3.35, 95 CI 2.12-5.27, P < 0.0001), but major bleeding that was not severe according to the study definitions did not.Conclusion: Non-fatal strokes increased mortality in ACTIVE-W, but non-disabling strokes did not. Among major bleeding events, only those also classified as severe increased mortality. Future research should emphasize the prevention of disabling strokes and severe bleeds and place less emphasis on non-disabling stroke or major bleeds that are not severe. © European Society of Cardiology The Author 2010.

It has been recognized that some lean individuals unexpectedly present with non-alcoholic steatohepatitis (NASH) [1] and in contrast, morbidly obese individuals present NASH in only about 14-37% of cases [2]. Although this situation is seemingly paradoxical, the discrepancy has been mostly attributed to the pattern of obesity being predominantly visceral/truncal, or peripheral/subcutaneous. Obesity, and particularly visceral fat (VF), is considered a key player in the development of the metabolic syndrome and its complications, namely cardiovascular risk and non-alcoholic fatty liver disease (NAFLD). Indeed, waist circumference, considered an indirect measurement of VF, is one criterion in the metabolic syndrome definition. © 2010 European Association for the Study of the Liver.

To determine the potential properties of commercial polyamide 12 (PA12) used in the selective laser sintering (SLS) process, multi-walled carbon nanotubes (MWCNTs) were dispersed in the polyamide powder by mechanical mixing to prepare a composite (PA/MWCNTs). Specimens of PA12 and PA/MWCNTs were manufactured by the SLS process. Infrared spectroscopy, X-ray diffraction and dynamic mechanical analysis were used to assess the structural and mechanical properties of the materials. Stress-strain tests showed higher values for flexural modulus and ultimate strength for the composite when compared to PA12 specimens. Changes in the viscoelastic properties suggest intermolecular interaction between the PA12 and MWCNTs. Fatigue tests show an improvement in the composite strength with the addition of MWCNTs, retarding the creep failure mechanism. © 2011 Elsevier Ltd. All rights reserved.

A reputation system to evaluate work is disclosed. Answer data for each of one or more unsupervised workers is received. The answer data includes one or more answers each representing a judgment by the worker that reflects on the quality of a given work product. The reputation system determines programmatically, based at least in part on a reputation data of an owner of the work product, the answer data, and a respective reputation data of the respective unsupervised workers, which answers are correct.
