PURPOSE To examine the comorbidity profile and update estimates of health care resource utilization for commercially insured, working-age adults with diabetic macular edema (DME) relative to a matched comparison group of diabetic adults without DME. Additional comparisons were made in the subgroup of pseudophakic patients. PATIENTS AND METHODS A retrospective matched-cohort study of commercia...

Advanced combustion systems that utilize different modes and alternative fuels have significantly improved performance emissions compared to conventional diesel or spark-ignited combustions. As an fuel, dimethyl ether (DME) has been receiving much attention as it runs effectively under low-temperature (LTC) such homogeneous charge compression ignition (HCCI) reactivity control (RCCI). Under com...

Dimethyl ether (DME) has been proposed to be a promising alternative to conventional diesel fuel because of its favorable compression ignition property (high cetane number) and its soot-free combustion. A radical chain mechanism for hydrocarbon autoignition has been proposed for DME at low temperatures. In this mechanism, the chain initiation step consists of DME undergoing hydrogen abstraction...

IMPORTANCE Diabetic macular edema (DME) is a leading cause of vision loss in persons with diabetes mellitus. Although there are national estimates for the prevalence of diabetic retinopathy and its risk factors among persons with diabetes, to our knowledge, no comparable estimates are available for DME specifically. OBJECTIVES To estimate the prevalence of DME in the US population and to iden...

Homogeneous charge compression ignition (HCCI) combustion enables higher thermal efficiency and lower NOx emission to be achieved in internal combustion engines compared to conventional combustion systems. A new concept HCCI engine system fueled with dimethyl ether (DME) with a high cetane number and methanol-reformed gas (MRG) with high anti-knock properties has been proposed by the author et ...

Introduction Emergency Medicine (EM) is a unique clinical learning environment. The American College of Graduate Medical Education Clinical Learning Environment Review Pathways to Excellence calls for "hands-on training" of disclosure of medical error (DME) during residency. Training and practicing key elements of DME using standardized patients (SP) may enhance preparedness among EM residents ...

PURPOSE To quantify dose mapping errors (DMEs) of a point-based dose mapping method for 4D lung treatment plans. METHODS Point-based dose mapping methods utilize deformation vector fields (DVFS) to interpolate dose from a deformed image. Volume-based dose mapping methods consider the volume overlap between deformed and reference voxels; defining dose as the integral energy divided by the inte...
