Physical activity (PA) is defined as bodily movement produced by skeletal muscles with energy expenditure beyond resting levels. PA is closely related to reduced morbidity and mortality in chronic obstructive pulmonary disease (COPD). Self-report questionnaires are often subject to recall bias, correlating poorly with objectively qualified PA, and do not provide an accurate estimate of free-living energy expenditure. PA may be objectively evaluated by newly developed tri-axial accelerometers by quantifying steps or body movements over a period of time...

This article describes a family that had to deal with grief from losing a family member. They sought help for 13-yr-old Katie's prolonged pain following a sprain. The family's unresolved grief over their second child's passing continued to emerge, peeping through the small talk, the wry smiles, the daily efforts to move and do, despite physical pain. As the demands of Katie's rehabilitation stripped away reserves of politeness and energy, the family's emotional pain became more fully uncovered.The author describes the 6-week course of physical and occupational therapies, pain medicine management, and individual and family behavioral health support...

Boron presents at physiological pH in the form of boric acid (BA), a molecule that has both positive and negative effects on biological processes. In medicine, BA is used as a topical treatment for vaginal yeast infections by Candida species because of its well-documented but poorly understood effect on inhibition of growth in general and of invasive, hyphal growth in particular. The present study examines the influence of BA on carbohydrate energy metabolism of this common human pathogen. Starting from previous findings about an inhibition of key NAD-dependent enzymes by BA in vitro, we confirmed that such an inhibition occurs in permeabilized C...

Molecular breast imaging (MBI) is a nuclear medicine test that uses dedicated gamma cameras designed for imaging of the breast. Despite growing adoption of MBI, there is currently a lack of guidance on appropriate quality control procedures for MBI systems. Tests designed for conventional gamma cameras either do not apply or must be modified for dedicated detectors. Our objective was to provide practical guidance for physics testing of MBI systems by adapting existing quality control procedures for conventional systems...
