In December 2017, the National Academy of Neuropsychology convened an interorganizational Summit on Population Health Solutions for Assessing Cognitive Impairment in Geriatric Patients in Denver, Colorado. The Summit brought together representatives of a broad range of stakeholders invested in the care of older adults to focus on the topic of cognitive health and aging. Summit participants specifically examined questions of who should be screened for cognitive impairment and how they should be screened in medical settings. This is important in the context of an acute illness given that the presence of cognitive impairment can have significant implications for care and for the management of concomitant diseases as well as pose a major risk factor for dementia. Participants arrived at general principles to guide future screening approaches in medical populations and identified knowledge gaps to direct future research. Key learning points of the summit included: * recognizing the importance of educating patients and healthcare providers about the value of assessing current and baseline cognition; * emphasizing that any screening tool must be appropriately normalized and validated in the population in which it is used to obtain accurate information, including considerations of language, cultural factors, and education; and * recognizing the great potential, with appropriate caveats, of electronic health records to augment cognitive screening and tracking of changes in cognitive health over time.

This paper attempts to trace the movement of a sled along a track at speeds up to Mach 4.5. The sled is supported with slippers that are loosely connected to the rail in such a way that sliding is allowed relative to the stationary rail, but the aerodynamic forces acting on the vehicle create bouncing effects within its movement. The model developed makes use of a finite-difference analysis of sliding and bouncing with a one-dimensional differential equation that includes possible melting. The results from this approach are incorporated into a two-dimensional finite-element model that treats the solution incrementally in time within a quasi-steady-state fashion. The results display temperature as a function of conduction and convection including the boundary-layer and Couette conditions along the lower surface. The aerodynamics and boundary layer along the leading edge and top surface are also included. The finite difference is integrated into a finite-element analysis to evaluate sliding, bouncing, and aerodynamic effects on a slipper as it traverses a rail at high velocity. The importance of the research is to determine the temperature profile that can be incorporated into a mechanical evaluation as related to material wear. [ABSTRACT FROM AUTHOR]
