The effect of type of femoral component fixation on mortality and morbidity after hip hemiarthroplasty:A systematic review and meta-analysis

Background: Hip hemiarthroplasty is a well-established treatment of displaced femoral neck fracture, although debate exists over whether cemented or uncemented fixation is superior. Uncemented prostheses have typically been used in younger, healthier patients and cemented prostheses in older patients with less-stable bone. Also, earlier research has suggested that bone cement has cytotoxic effects and may trigger cardiovascular and respiratory adverse events. Questions/Purposes: The aim of this systematic review and meta-analysis was to compare morbidity and mortality rates after cemented and uncemented hemiarthroplasty for the treatment of displaced femoral neck fractures in elderly patients. Methods: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched seven medical databases for randomized clinical trials and observational studies. We compared cemented and uncemented hemiarthroplasty using the Harris Hip Score (HHS), as well as measures of postoperative pain, mortality, and complications. Data were extracted and pooled as risk ratios or standardized mean difference with their corresponding 95% confidence intervals in a meta-analysis model. Results: The meta-analysis included 34 studies (12 randomized trials and 22 observational studies), with a total of 42,411 patients. In the pooled estimate, cemented hemiarthroplasty was associated with less risk of postoperative pain than uncemented hemiarthroplasty. There were no significant differences between groups regarding HHS or rates of postoperative mortality, pulmonary embolism, cardiac arrest, myocardial infarction, acute cardiac arrhythmia, or deep venous thrombosis. Conclusions: While we found that cemented hemiarthroplasty results in less postoperative pain than uncemented hemiarthroplasty in older patients with femoral neck fracture, the lack of significant differences in functional hip scores, mortality, and complications was surprising. Further high-level research is needed

Self-Help Acceptance and Commitment Therapy for Carers of People with Multiple Sclerosis: A Feasibility Randomised Controlled Trial

Introduction: Acceptance and Commitment Therapy (ACT) is an established psychological therapy, but its effectiveness for carers of people with Multiple Sclerosis experiencing carer-related strain has not been established. This study assessed the acceptability and feasibility of conducting a randomised controlled trial comparing ACT self-help, telephone-supported ACT self-help, and usual care. Methods: We describe a mixed-method, parallel three-armed feasibility randomised controlled trial. Participants were carers (i.e. caregivers) of people with multiple sclerosis. The self-help group received an ACT self-help text (covered over eight weeks), the enhanced self-help group additionally received weekly telephone support. All participants completed questionnaires at baseline, three-months, and six-months post-randomisation, assessing carer strain, health-related quality of life, and ACT-related processes. A sample of participants were also interviewed. Results: Twenty-four carers were randomised. Participants found the study procedures to be acceptable, but highlighted difficulties with the self-help text and timing of the intervention. An exploratory, group-level analysis indicated effectiveness for the enhanced self-help group on carer strain (consistent across both follow-ups), with convergent qualitative reports to support this. Discussion: A full trial of ACT-based, telephone-supported self-help is warranted, including both the self-help and enhanced self-help design, following significant adaptions to the self-help itself. An internal pilot would, therefore, be recommended to further assess the feasibility after changes are incorporated
