BackgroundInfection remains a leading cause of failure of hip and knee replacements. Infection burden is the ratio of implants revised for infection to the total number of arthroplasties in a specific period, measuring the steady state of infection in a registry. We hypothesized infection burden would be similar among arthroplasty registries.MethodsWe evaluated publicly reported data from 6 arthroplasty registries (Australian Orthopaedic Association National Joint Replacement Registry [AOANJRR], New Zealand Joint Registry, Swedish Hip Arthroplasty Register, Swedish Knee Arthroplasty Register, National Joint Registry of England, Wales, Northern Ireland, and the Isle of Man, and the American Joint Replacement Registry) for revisions performed with an infection diagnosis over the last 6 years.ResultsThe 2015 hip infection burden varied between registries from 0.76% (AOANJRR) to 1.24% (Swedish Hip Arthroplasty Register), and the unweighted overall average for hip infection burden was 0.97%. In 2012, 2013, and 2014, average hip infection burden held steady at 0.87%, 0.93%, and 0.94%, respectively, higher than the preceding 2 years. The 2015 knee infection burden varied from 0.88% (AOANJRR) to 1.28% (Swedish Knee Arthroplasty Register), and the unweighted average was 1.03%. In 2012, 2013, and 2014, knee infection burden was 1.04%, 1.11%, and 1.02%, respectively. These numbers were also higher than the preceding 2 years.ConclusionsInfection burden may be one measure of the overall success in registry populations as well as monitoring the steady state of infection worldwide. Despite global efforts to reduce postoperative infection, infection burden has actually increased in the selected registries over time.

IMPORTANCEMistreatment is a common experience among surgical residents and is associated with burnout. Women have been found to experience mistreatment at higher rates than men. Further characterization of surgical residents' experiences with gender discrimination and sexual harassment may inform solutions.OBJECTIVE To describe the types, sources, and factors associated with (1) discrimination based on gender, gender identity, or sexual orientation and (2) sexual harassment experienced by residents in general surgery programs across the US. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional national survey study was conducted after the 2019 American Board of Surgery In-Training Examination (ABSITE). The survey asked respondents about their experiences with gender discrimination and sexual harassment during the academic year starting July 1, 2018, through the testing date in January 2019. All clinical residents enrolled in general surgery programs accredited by the Accreditation Council for Graduate Medical Education were eligible. EXPOSURES Specific types, sources, and factors associated with gender-based discrimination and sexual harassment.MAIN OUTCOMES AND MEASURES Primary outcome was the prevalence of gender discrimination and sexual harassment. Secondary outcomes included sources of discrimination and harassment and associated individual-and program-level factors using gender-stratified multivariable logistic regression models. RESULTSThe survey was administered to 8129 eligible residents; 6956 responded (85.6% response rate)from 301 general surgery programs. Of those, 6764 residents had gender data available (3968 [58.7%] were male and 2796 [41.3%] were female individuals). In total, 1878 of 2352 female residents (79.8%) vs 562 of 3288 male residents (17.1%) reported experiencing gender discrimination (P < .001), and 1026 of 2415 female residents (42.5%) vs 721 of 3360 male residents (21.5%) reported experiencing sexual harassment (P < .001). The most common type of gender discrimination was being mistaken for a nonphysician (1943 of 5640 residents [34.5%] overall; 1813 of 2352 female residents [77.1%]; 130 of 3288 male residents [4.0%]), with patients and/or families as the most frequent source. The most common form of sexual harassment was crude, demeaning, or explicit comments (1557 of 5775 residents [27.0%] overall; 901 of 2415 female residents [37.3%]; 656 of 3360 male residents [19.5%]); among female residents, the most common source of this harassment was patients and/or families, and among male residents, the most common source was coresidents and/or fellows. Among female residents, gender discrimination was associated with pregnancy (odds ratio [OR], 1.93; 95% CI, 1.03-3.62) and higher ABSITE scores (highest vs lowest quartile: OR, 1.67; 95% CI, 1.14-2.43); among male residents, gender discrimination was associated with parenthood (OR, 1.72; 95% CI, 1.31-2.27) and lower ABSITE scores (highest vs lowest quartile: OR, 0.57; 95% CI, 0.43-0.76). Senior residents were more likely to report experien...

Purpose This study examined secondary benefits of an individualized physical activity intervention on improving dementia family caregivers’ subjective burden, depressive symptoms and positive affect. Design and Methods A community-based randomized controlled trial (RCT) was implemented with family caregivers of persons with dementia (N = 211) who received the Enhanced Physical Activity Intervention (EPAI: treatment intervention, n = 106) or the Caregiver Skill Building Intervention (CSBI: control intervention, n = 105). Interventions were delivered over 12 months, including a baseline home visit and regularly spaced telephone calls. Data were collected in person at baseline, 6 and 12-months; and telephonically at 3 and 9-months. The EPAI integrated physical activity and caregiving content while the CSBI focused only on caregiving content. Descriptive, bivariate and intention-to-treat analyses using generalized estimating equations (GEE) were performed to examine secondary benefits of the EPAI on family caregiver burden, depressive symptoms and positive affect. Results Compared to caregivers in the CSBI group, caregivers in the EPAI significantly increased their overall and total moderate physical activity and showed a positive interaction between the intervention and time for positive affect at both six (p = 0.01) and 12-months (p = 0.03). The EPAI was significantly associated with improving burden at 3 months (p = 0.03) but had no significant effect on depressive symptoms. Implications Caregiver involvement in an individualized physical activity intervention was associated with increased overall and total moderate physical activity and improved positive affect from baseline to 12 months. Improved positive affect may help caregivers to feel better about themselves and their situation, and better enable them to continue providing care for their family member for a longer time at lower risk to their own mental health.

This paper presents the efficacy of the recruitment framework used for a clinical trial with sedentary family caregivers of persons with Alzheimer’s disease. An integrated social marketing approach with principles of community-based participatory research provided the theoretical framework for organizing recruitment activities. This multi-pronged approach meant that caregivers were identified from a range of geographic locations and numerous sources including a federally funded Alzheimer’s disease center, health care providers, community based and senior organizations, and broad-based media. Study enrollment projections were exceeded by 11% and resulted in enrolling N = 211 caregivers into this clinical trial. We conclude that social marketing and community-based approaches provide a solid foundation for organizing recruitment activities for clinical trials with older adults.
