: As total knee arthroplasty (TKA) patients are getting more active, heavier and younger and structural material fatigue and delamination of tibial inserts becomes more likely in the second decade of good clinical performance it appears desirable to establish advanced pre-clinical test methods better characterizing the longterm clinical material behaviour. The questions of our study were 1) Is it possible to induce subsurface delamination and striated pattern wear on standard polyethylene TKA gliding surfaces? 2) Can we distinguish between γ-inert standard polyethylene (PEstand...

PURPOSE: To review the literature on the existent evidence considering the use of power wheel chair (PWC) for children with DMD who can still walk independently. METHODS: A systematic literature search was conducted through nine databases by the three authors independently. Both quantitative and qualitative research designs were considered for inclusion. Studies were included only if the study population consisted of ambulatory children diagnosed with DMD. Data extraction was on participant characteristics, level of walking and on outcomes in term of impairment, function and participation domains (ICF, World Health Organization, 2001) in accordance to a structured diagram by the three authors independently...

BACKGROUND: Total hip arthroplasty (THA) is one of the most common orthopaedic operations performed worldwide. Painful osteoarthritis of the hip is the primary indication for THA. Following THA, people have conventionally been provided with equipment, such as raised toilet seats and chairs, and educated to avoid activities that could cause the hip joint to be in a position of flexion over 90 degrees, or adduction or rotation past the midline. These aspects of occupational therapy have been advocated to reduce the risks of prosthesis dislocation...

This Special Communication summarizes the key points raised at the Society of Surgical Chairs mentorship panel sessions held at the 2014 and 2015 annual meetings of the society. Highlights of these expert panel discussions include senior chairs' insights into successfully dealing with increasingly complex academic medical organizations and horizontal department management expectations in the context of the arrival of the Millennial Generation into the work force. Three key tenets of effective surgery leadership that arose from these sessions deal with the importance of (1) collaboration and cooperativity, (2) humanized relationships and mentorship, and (3) operational efficiency...

Motor development-traditionally described in terms of age-related stages-is typically studied in the laboratory with participants of Western European descent. Cross-cultural studies typically focus on group differences in age-related stages relative to Western norms. We adopted a less traditional approach: We observed 5-month-olds and their mothers from six cultural groups around the world during one hour at home while they engaged in natural daily activities. We examined group differences in infants' sitting proficiency, everyday opportunities to practice sitting, the surfaces on which sitting took place, and mothers' proximity to sitting infants...

Training techniques that prepare laboratory animals to participate in testing via cooperation are useful tools that have the potential to benefit animal wellbeing. Understanding how animals systematically vary in their cooperative training trajectories will help trainers to design effective and efficient training programs. In the present report we document an updated method for training rhesus monkeys to cooperatively participate in restraint in a 'primate chair.' We trained 14 adult male macaques to raise their head above a yoke and accept yoke closure in an average of 6...

Organizations worldwide compile results from scientific studies, and grade the evidence of interventions, in order to assist policy makers. However, quality of evidence alone is seldom sufficient to make a recommendation. The Developing and Evaluating Communication Strategies to Support Informed Decisions and Practice Based on Evidence (DECIDE) framework aims to facilitate decision making and to improve dissemination and implementation of recommendations in the healthcare and public health sector. The aim of this study was to investigate whether the DECIDE framework is applicable in the public health field in Sweden...

Francis Xavier Dercum (1856-1931) is known primarily for his prominence in the field of neurology and for his identification of "Adiposis Dolorosa", known as Dercum's disease. His brilliance, however, extends well beyond neurology. Born and raised in Philadelphia to parents of American and European descent, Dercum's natural curiosity oriented his interests toward medicine and philosophy. His scholarship flourished, and much recognition came his way. He died in Benjamin Franklin's Chair, closing what would be his last session as President of the American Philosophical Society...

BACKGROUND: Although variations among institutional review boards (IRBs) have been documented for 30 years, they continue, raising crucial questions as to why they persist as well as how IRBs view and respond to these variations. METHODS: In-depth, 2-hour interviews were conducted with 46 IRB chairs, administrators, and members. The leadership of 60 U.S. IRBs were contacted (every fourth one in the list of the top 240 institutions by NIH funding). IRB leaders from 34 of these institutions were interviewed (response rate = 55%)...
