RESUMEN
BACKGROUND: To assess the quality of clinical practice guidelines (CPGs) for chronic limb-threatening ischemia (CLTI) using the Appraisal of Guidelines for Research and Evaluation II instrument. METHODS: A systematic review of Medline, Embase, and online CPG databases was carried out. Four CPGs on CLTI were identified: Global Vascular Guidelines (GVG), European Society of Cardiology (ESC), American College of Cardiology, and National Institute for Health and Care Excellence guidelines on lower limb peripheral arterial disease. Two independent appraisers analyzed the 4 CPGs using the Appraisal of Guidelines for Research and Evaluation II instrument. CPGs were ranked across 6 domains with 23 items that ranged from 1 (strongly disagree) to 7 (strongly agree). A scaled domain score was calculated as a percentage of the maximum possible score achievable. A domain score of ≥50% and an overall average domain score of ≥80% reflected a CPG of adequate quality recommended for use. RESULTS: GVG had the highest overall score (82.9%), as an average of all domains, and ESC had the lowest score (50.2%). GVG and National Institute for Health and Care Excellence guidelines had all domains scoring >50%, while American College of Cardiology had 5 and ESC had 3. Two domains, rigor of development and applicability, scored the lowest among the CPGs. There was a lack of detail in describing systematic methods used in the literature review, how guidelines were formulated with minimal bias, and the planned procedure for updating the guidelines. Implications of guideline application and monitoring of outcomes after implementations were not explicitly discussed. CONCLUSIONS: The GVG guideline published in 2019 discussing CLTI is assessed to be of high quality and recommended for use. This review helps to improve clinical decision-making and quality of future CPGs for CLTI.

BACKGROUND: Depression is associated with inferior outcomes following hip or knee arthroplasty, though it remains unclear if this relationship is modifiable. This study examined the association between pharmacologic treatment of depression and patient-reported outcomes. METHODS: This retrospective cohort study of 1,651 total hip arthroplasty (THA) and 1,792 total knee arthroplasty (TKA) procedures between October 2012 and June 2019 used institutional registry data linked to nationwide pharmaceutical claims. The primary outcome was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) global score, with pain and function sub-scales assessed as secondary outcomes. The TKA and THA patients were analyzed separately via mixed-effect linear regression to compare patients who had depression treated with antidepressants (TKA, n = 210; THA, n = 150) to those who had untreated depression (TKA, n = 43; THA; n = 50), and those who did not have depression (TKA, n = 1,539; THA, n = 1,451). RESULTS: Among patients who had depression, not receiving preoperative antidepressant therapy was associated with smaller improvements in WOMAC global scores (TKA, adjusted mean difference [MD]: -13.1 points, 95% CI [confidence interval]: -21.4 to -4.8; THA, MD: -8.5 points, 95% CI: -15.7 to -1.2) at two years after surgery, but not at one year (TKA, MD: -5.4 points, 95% CI: -12.9 to 2.1; THA, MD: -6.3 points, 95% CI: -12.9 to 0.3). Those who did not have depression had similar improvements in WOMAC global scores to those who had treated depression at both one (TKA, MD: 0.8 points, 95% CI: -2.7 to 4.4; THA, MD: 1.8 points, 95% CI: -1.8 to 5.4) and two years (TKA, MD: -1.1 points, 95% CI: -4.9 to 2.7; THA, MD: -1.6 points, 95% CI: -5.6 to 2.3). The findings were consistent with secondary outcomes. CONCLUSION: Among patients who have depression, antidepressant therapy before TKA or THA is associated with improved outcomes. Additional studies are needed to establish the impact of interventions to address untreated depression before surgery.
RESUMEN
Current guidelines recommend the use of radiotherapy in the management of intermediate and high-grade soft-tissue sarcoma of the extremity and trunk wall. Its use in low-grade sarcoma is less clear. To date there have been no pooled data analyses regarding its role in this context. Its use is not without complications and therefore must be justified. We aim to assess the oncological impact of radiotherapy versus limb-sparing surgery alone in this subset of sarcoma. Medline, EMBASE and Cochrane's databases were searched from 1982 to present. Studies on or having a subgroup analysis of low-grade soft tissue sarcoma, with a radiotherapy and a surgery only arm were included. Outcomes included local recurrence and overall survival. Patients were at least 16 years of age with primary de-novo sarcoma who had not undergone prior resection or treatment. Those undergoing concomitant therapy were excluded. Data extraction was performed independently by two reviewers. Results were pooled using a random-effects model and presented as a forest plot. Primary outcome measures included local recurrence and overall survival. Eleven unique studies were included, consisting of two RCTs and nine non-randomized studies. Overall, there were 12 799 patients. Four studies were included in meta-analysis and the overall pooled effect showed a limited role of radiotherapy in overall survival outcomes when compared to limb-sparing surgery alone HR 1.00 [0.83-1.20] P = 0.41. Descriptive analysis suggests there is limited role of radiotherapy in improving local recurrence outcomes. This study suggests there is limited role for radiotherapy versus limb-sparing surgery alone in low-grade soft-tissue sarcoma. These findings strongly suggest there is lack of high-quality data and that further research must be undertaken prior to forming any strong conclusions regarding the management of low-grade soft-tissue sarcoma. Demonstrating a role for radiotherapy may help improve the quality of excisional margins and thus potentiate limb-sparing surgery.

Importance: Despite the increasing number of tools available to predict the outcomes of total knee arthroplasty (TKA), the effect of these predictive tools on patient decision-making remains uncertain. Objective: To assess the effect of an online predictive tool on patient-reported willingness to undergo TKA. Design, Setting, and Participants: This parallel, double-masked, 2-arm randomized clinical trial compared predictive tool use with treatment as usual (TAU). The study was conducted between June 30, 2022, and July 31, 2023. Participants were followed up for 6 months after enrollment. Participants were recruited from a major Australian private health insurance company and from the surgical waiting list for publicly funded TKA at a tertiary hospital. Eligible participants had unilateral knee osteoarthritis, were contemplating TKA, and had previously tried nonsurgical interventions, such as lifestyle modifications, physiotherapy, and pain medications. Intervention: The intervention group was provided access to an online predictive tool at the beginning of the study. This tool offered information regarding the likelihood of improvement in quality of life if patients chose to undergo TKA. The predictions were based on the patient's age, sex, and baseline symptoms. Conversely, the control group received TAU without access to the predictive tool. Main Outcomes and Measures: The primary outcome measure was the reduction in participants' willingness to undergo surgery at 6 months after tool use as measured by binomial logistic regression. Secondary outcome measures included participant treatment preference and the quality of their decision-making process as measured by the Knee Decision Quality Instrument. Results: Of 211 randomized participants (mean [SD] age, 65.8 [8.3] years; 118 female [55.9%]), 105 were allocated to the predictive tool group and 106 to the TAU group. After adjusting for baseline differences in willingness for surgery, the predictive tool did not significantly reduce the primary outcome of willingness for surgery at 6 months (adjusted odds ratio, 0.85; 95% CI, 0.42-1.71; P = .64). Conclusions and Relevance: Despite the absence of treatment effect on willingness for TKA, predictive tools might still enhance health outcomes of patients with knee osteoarthritis. Additional research is needed to optimize the design and implementation of predictive tools, address limitations, and fully understand their effect on the decision-making process in TKA.

OBJECTIVE: We aimed to evaluate the accuracy of clinical tests that are used to diagnose greater trochanteric pain syndrome (GTPS) in clinical practice. DESIGN: Diagnostic test accuracy systematic review with meta-analysis. LITERATURE SEARCH: MEDLINE, Embase, CINAHL, AMED, and SPORTDiscus were searched using key words mapped to diagnostic test accuracy for GTPS. STUDY SELECTION CRITERIA: Studies with published or derivable diagnostic accuracy data were included. DATA SYNTHESIS: Risk of bias was assessed using the QUADAS-2 tool, and certainty of evidence, via the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework. MetaDTA "R" random-effects models were used to summarize individual and pooled data including sensitivity, specificity, likelihood ratios, and pretest/posttest probabilities. RESULTS: From a database yield of 858 studies, 23 full texts were assessed. We included 6 studies for review, involving 15 tests and 272 participants (314 hips). Overall certainty of evidence ranged from very low to moderate. Meta-analysis of 6 tests revealed sequenced test clusters able to significantly shift pretest-posttest probability for or against a GTPS diagnosis. In people reporting lateral hip pain, a negative gluteal tendon (GT) palpation test followed by a negative resisted hip abduction test significantly reduced the posttest probability of GTPS from 59% to 14%. In those with a positive GT palpation test followed by a positive resisted hip abduction test, the posttest probability of GTPS significantly shifted from 59% to 96%. CONCLUSION: The value of magnetic resonance imaging for diagnosing GTPS is debated. We have identified a straightforward, clinically useful diagnostic test cluster to help confirm or refute the presence of GTPS in people reporting lateral hip pain.

Background: Suboptimal clinical trial recruitment contributes to research waste. Evidence suggests there may be gender-based differences in willingness to participate in clinical research. Identifying gender-based differences impacting the willingness of trial participation may assist trial recruitment. Objectives: To examine factors that influence the willingness of men and women to participate in clinical trials and to identify modifiable factors that may be targeted to optimise trial participation. Material and methods: Electronic databases were searched with key words relating to 'gender', 'willingness to participate' and 'trial'. Included studies were English language and reported gender-based differences in willingness to participate in clinical trials, or factors that influence a single gender to participate in clinical trials. Studies were excluded if they described the demographic factors of trial participants or if the majority of participants were pregnant. Extracted data were coded, categorized, analysed thematically and interpreted using Arksey and O'Malley's framework. Results: Sixty-three studies were included. Two main themes were identified: trial characteristics and participant characteristics. A number of gender-based differences moderating willingness to participate were observed although only one, 'concern for self' was found to influence actual trial participation rates between genders. Conclusion: The relationship between factors influencing willingness to participate in clinical trials is complex. The influence of gender on willingness to participate, while important, may be moderated by other factors including socioeconomic status, ethnicity and health condition. Exploring factors that influence willingness to participate specific to a study cohort likely offers the most promise to optimise trial recruitment of that cohort.
RESUMEN
Introduction: Bone tumors, characterized by diverse locations and shapes, often necessitate surgical excision followed by custom implant placement to facilitate targeted bone reconstruction. Leveraging additive manufacturing, patient-specific implants can be precisely tailored with complex geometries and desired stiffness, enhancing their suitability for bone ingrowth. Methods: In this work, a finite element model is employed to assess patient-specific lattice implants in femur bones. Our model is validated using experimental data obtained from an animal study (n = 9). Results: The results demonstrate the accuracy of the proposed finite element model in predicting the implant mechanical behavior. The model was used to investigate the influence of reducing the elastic modulus of a solid Ti6Al4V implant by tenfold, revealing that such a reduction had no significant impact on bone behavior under maximum compression and torsion loading. This finding suggests a potential avenue for reducing the endoprosthesis modulus without compromising bone integrity. Discussion: Our research suggests that employing fully lattice implants not only facilitates bone ingrowth but also has the potential to reduce overall implant stiffness. This reduction is crucial in preventing significant bone remodeling associated with stress shielding, a challenge often associated with the high stiffness of fully solid implants. The study highlights the mechanical benefits of utilizing lattice structures in implant design for enhanced patient outcomes.
