BACKGROUND Many patients with severe aortic stenosis and coexisting conditions are not candidates for surgical replacement of the aortic valve. Recently, transcatheter aortic-valve implantation (TAVI) has been suggested as a less invasive treatment for high-risk patients with aortic stenosis. METHODS We randomly assigned patients with severe aortic(More)
BACKGROUND The use of transcatheter aortic-valve replacement has been shown to reduce mortality among high-risk patients with aortic stenosis who are not candidates for surgical replacement. However, the two procedures have not been compared in a randomized trial involving high-risk patients who are still candidates for surgical replacement. METHODS At 25(More)
BACKGROUND The Placement of Aortic Transcatheter Valves (PARTNER) trial showed that among high-risk patients with aortic stenosis, the 1-year survival rates are similar with transcatheter aortic-valve replacement (TAVR) and surgical replacement. However, longer-term follow-up is necessary to determine whether TAVR has prolonged benefits. METHODS At 25(More)

BACKGROUND Transcatheter aortic-valve replacement (TAVR) is the recommended therapy for patients with severe aortic stenosis who are not suitable candidates for surgery. The outcomes beyond 1 year in such patients are not known. METHODS We randomly assigned patients to transfemoral TAVR or to standard therapy (which often included balloon aortic(More)

Negotiation researchers theorize that individual differences are determinants of bargaining processes and outcomes but have yet to establish empirically the role of individual differences. In 2 studies the authors used bargaining simulations to examine the roles of personality and cognitive ability in distributive (Study 1 ) and integrative (Study 2)(More)
BACKGROUND Previous trials have shown that among high-risk patients with aortic stenosis, survival rates are similar with transcatheter aortic-valve replacement (TAVR) and surgical aortic-valve replacement. We evaluated the two procedures in a randomized trial involving intermediate-risk patients. METHODS We randomly assigned 2032 intermediate-risk(More)
We describe a new species of the remarkable whalebone-eating siboglinid worm genus, Osedax, from a whale carcass in the shallow north Atlantic, west of Sweden. Previously only recorded from deep-sea (1500-3000 m) whale-falls in the northeast Pacific, this is the first species of Osedax known from a shelf-depth whale-fall, and the first from the Atlantic(More)
We examined an autopsy series of 14 children with shaken baby syndrome (SBS) who lacked skull fracture. Evidence of axonal injury was sought using immunohistochemical stains for neurofilament, 68-kDa neurofilament and β-amyloid precursor protein (βAPP). βAPP-positive axons were present in the cerebral white matter of all cases of SBS but were also present(More)
The Antarctic continental shelf is large, deep (500–1000m), and characterized by extreme seasonality in sea-ice cover and primary production. Intense seasonality and short pelagic foodwebs on the Antarctic shelf may favor strong benthopelagic coupling, whereas unusual water depth combined with complex topography and circulation could cause such coupling to(More)
