OBJECTIVE To add to the evidence on comparative long-term effects of insulin analog glargine versus human NPH insulin on the risk for cancer. RESEARCH DESIGN AND METHODS We identified cohorts of initiators of glargine and human NPH without an insulin prescription during the prior 19 months among patients covered by the Inovalon Medical Outcomes Research(More)
Methyl chloroform (CH3CCl3, 1,1,1,-trichloroethane) was used widely as a solvent before it was recognized to be an ozone-depleting substance and its phase-out was introduced under the Montreal Protocol. Subsequently, its atmospheric concentration has declined steadily and recent European methyl chloroform consumption and emissions were estimated to be less(More)
OBJECTIVES This study characterizes primary petroclival meningioma growth rates, before intervention, using volumetric analysis. In addition, predictors of growth are analyzed. METHODS Patients with previously untreated petroclival meningiomas were retrospectively reviewed (1999-2015). Image analysis software was used to perform volumetric analyses of(More)
C ontinuous-flow ventricular assist devices (CVADs) are more compact, less costly, and potentially more durable than pulsatile ventricular assist devices (PVADs). However, studies in animal models suggest that long-term continuous-flow support can result in hemodynamic dysfunction. This includes the disruption of the renin-angiotensin system and the(More)
OBJECTIVES To compute a benchmark for tracking readmission rates among patients enrolled in Medicare's private comprehensive Medicare Advantage (MA) plans and to develop preliminary comparisons with the fee-for-service (FFS) readmission rates. STUDY DESIGN Descriptive data presentation with analytic discussion. METHODS We computed a benchmark for(More)

In recent years, extensive research in the HCI literature has explored interactive techniques for digital fabrication. However, little attention in this body of work has examined how to involve and guide human workers in fabricating larger-scale structures. We propose a novel model of <i>crowdsourced fabrication</i>, in which a large number of workers and(More)
Education quality directly influences the effectiveness of teaching and has been widely subjected to public attention; however, the content of education quality and the interaction among the various factors are still not known. In order to effectively control education quality, the educational administration hopes to continue to improve education quality(More)
