Test accuracy of short screening tests for diagnosis of delirium or cognitive impairment in an acute stroke unit setting.

Background And Purpose: Guidelines recommend cognitive screening in acute stroke. Various instruments are available, with no consensus on a preferred tool. We aimed to describe test accuracy of brief screening tools for diagnosis of cognitive impairment and delirium in acute stroke.

Decision analysis for designing marine protected areas for multiple species with uncertain fishery status.

Marine protected areas (MPAs) are growing in popularity as a conservation tool, and there are increasing calls for additional MPAs. Meta-analyses indicate that most MPAs successfully meet the minimal goal of increasing biomass inside the MPA, while some do not, leaving open the important question of what makes MPAs successful. An often-overlooked aspect of this problem is that the success of fishery management outside MPA boundaries (i.

Marine reserve networks for species that move within a home range.

Marine reserves are expected to benefit a wide range of species, but most models used to evaluate their effects assume that adults are sedentary, thereby potentially overestimating population persistence. Many nearshore marine organisms move within a home range as adults, and there is a need to understand the effects of this type of movement on reserve performance. We incorporated movement within a home range into a spatially explicit marine reserve model in order to assess the combined effects of adult and larval movement on persistence and yield in a general, strategic framework.

The pore size of polycaprolactone scaffolds has limited influence on bone regeneration in an in vivo model.

Bone tissue engineering scaffolds should be designed to optimize mass transport, cell migration, and mechanical integrity to facilitate and enhance new bone growth. Although many scaffold parameters could be modified to fulfill these requirements, pore size is an important scaffold characteristic that can be rigorously controlled with indirect solid freeform fabrication. We explored the effect of pore size on bone regeneration and scaffold mechanical properties using polycaprolactone (PCL) scaffolds designed with interconnected, cylindrical orthogonal pores.
