Exploring the impact of pulse oximeter selection within the COVID-19 home-use pulse oximetry pathways.

Background: During the COVID-19 pandemic, portable pulse oximeters were issued to some patients to permit home monitoring and alleviate pressure on inpatient wards. Concerns were raised about the accuracy of these devices in some patient groups. This study was conducted in response to these concerns.

3D ultrasound to quantify lateral hip displacement in children with cerebral palsy: a validation study.

Aim: To assess the validity of a new index, lateral head coverage (LHC), for describing hip dysplasia in a population of children with cerebral palsy (CP).

Method: LHC is derived from 3D ultrasound assessment. Twenty-two children (15 males, seven females; age 4-15y) with CP undergoing routine hip surveillance were recruited prospectively for the study.

Investigating the impact of measurement uncertainty in the radiographic surveillance of hip displacement in cerebral palsy: A Monte Carlo simulation.

Hip surveillance programmes have greatly improved the management of hip dysplasia in children with cerebral palsy. Reimer's migration percentage is the most common index for quantifying hip dysplasia from planar radiographs. However, measurement uncertainty could undermine the diagnostic accuracy.

Typological review of environmental performance metrics (with illustrative examples for oil spill response).

An intensification of interest in environmental assessment during the last 2 decades has driven corporate efforts to better document environmental goals, improve environmental management systems, and increase awareness of the environmental and ecological effects of business operations. This trend has been motivated partly by regulatory requirements (such as the Toxics Release Inventory in the United States) and partly by the inclination of some large manufacturing firms to embrace a broader social and environmental mission characterized as "sustainability" or "ecoefficiency." Moreover, the importance of measurable objectives in the US government has been recognized at least since the Government Performance Results Act of 1993, which was intended to both improve the efficiency of government and the confidence of the American public in government managers.
