Background Although regional anesthesia (RA) is associated with improved pain control, reduced opioid use, and accelerated recovery after arthroplasty, racial and geographic differences have been identified in hip and knee arthroplasty, with limited data for shoulder and ankle arthroplasty. We examined differences in RA utilization for shoulder, hip, knee, and ankle arthroplasty, based on patient-level and hospital-level characteristics. Methods Using the National Inpatient Sample, we conducted a cross-sectional study of adults who underwent shoulder, hip, knee, and ankle arthroplasties from 2016 to 2020. RA was defined using procedure codes for neuraxial anesthesia and peripheral nerve blocks. Weighted descriptive statistics summarized RA utilization and compared patient-level and hospital-level characteristics using standardized mean differences (SMDs), with ≥0.10 indicating meaningful differences. Results We identified 1132 011 unweighted admissions, representing approximately 5.7 million weighted arthroplasties. RA was used in 7.0% of cases. RA utilization varied by procedure type, with the highest rates in shoulder (11.4%) and ankle arthroplasty (11.4%), followed by knee (9.1%) and hip arthroplasty (2.4%). Variation in RA utilization was observed in ankle arthroplasty based on race (SMD=0.11) and primary payer (SMD=0.12). RA use also varied by hospital size for shoulder (SMD=0.13), hip (SMD=0.29), and knee arthroplasty (SMD=0.22), by hospital location and teaching status for shoulder (SMD=0.17), hip (SMD=0.18), knee (SMD=0.19), and ankle arthroplasty (SMD=0.12), and by geographic region for shoulder (SMD=0.26), hip (SMD=0.45), knee (SMD=0.24), and ankle arthroplasty (SMD=0.17). Conclusions There is notable variation in RA use for inpatient arthroplasty across hospitals and geographic regions, with limited variation based on patient characteristics. These findings highlight the presence of system-level variation in RA use and underscore the need for further research to better understand the drivers of these patterns.

In 2024, the Journal of Wound Care ( JWC ) published best-practice guidance on wound debridement. This introduced the concept of integral debridement, defined as the combined use of complementary debridement methods on the same wound to optimise healing outcomes. This typically involves combining less invasive approaches, such as autolytic debridement, with more active adjunctive methods, including mechanical and/or sharp debridement. In 2026, JWC convened an expert panel to explore how this concept can be effectively implemented in non-specialist settings. The panel concluded that debridement is most effective when applied repeatedly throughout the healing process and introduced the concept of continuous integral debridement (CID), a cyclical four-step approach comprising cleanse, debride, cleanse and dress (CDCD). The panel propose that, when performed regularly, this will help disrupt microbial and non-microbial barriers to healing and maintain a clean wound environment. The panel consider that CID is compatible with established frameworks, such as TIME/TIMERS and the International Wound Infection Institute wound infection continuum, and complements antibiofilm strategies, including Wound Hygiene. This document provides practical guidance for integrating CID into routine wound care across all clinical settings, including recommendations on cleansing solutions, debridement methods and dressing selection, with the aim of supporting evidence-based practice and improving patient outcomes.

Abstract Aims Social isolation (SI) is associated with a higher risk of cardiovascular disease (CVD). One mechanism linking SI and CVD is accelerated biological ageing, which can be assessed using artificial intelligence-enabled electrocardiography (AI-ECG). We investigated whether longitudinal changes in SI status are associated with changes in biological ageing patterns. Methods and results A retrospective longitudinal cohort study including 17 663 individuals without significant CVD who completed ≥2 Berkman and Syme Social Network Index and had paired ECGs within 1 year of each questionnaire. Longitudinal SI status was defined by comparing baseline and follow-up SI status. Ageing trends were assessed using Δage-gap, defined as the change in the gap between AI-ECG-predicted age and chronological age from baseline to follow-up. Linear regression models predicting Δage-gap and survival analyses with Kaplan–Meier and multivariable Cox regression for all-cause mortality were performed. Persistently connected individuals were older [63.1 (52.1, 70.6) years] and had a higher prevalence of hyperlipidaemia and hypertension, yet demonstrated more favourable ageing trajectories. Similarly, those who became connected showed a non-significant attenuation of accelerated ageing. In multivariable linear regression, being persistently isolated [β = +0.412 years, P < 0.001] or becoming isolated [β = +0.438 years, P = 0.012] was associated with accelerated ageing compared to being persistently connected. In survival analyses, becoming isolated (aHR = 1.94, 95% CI = 1.53–2.46, P < 0.001) and being persistently isolated (aHR = 1.66, 95% CI = 1.40–1.96, P < 0.001) were associated with significantly higher all-cause mortality, independent of chronological age and comorbidities. Conclusion Persistent social connection is associated with slower biological ageing and lower mortality. The effects of SI on ageing and survival appear to be potentially reversible, calling for a prospective study to evaluate interventions aimed at improving both the social and biological burden of SI.

Abstract Aims Heart failure (HF), a major global health challenge, affects millions worldwide and poses substantial healthcare and economic burdens. It is estimated that a large proportion of those with early systolic dysfunction remain asymptomatic at a stage when guideline-directed medical therapies have been shown to prevent disease progression. To develop an artificial intelligence (AI) model capable of predicting abnormal left ventricular ejection fraction (EF) directly from static, non-gated, non-contrast chest computed tomography (CT) scans as a form of opportunistic screening, Methods and results Using a multi-institutional dataset of 34 058 paired non- contrast CT images and echocardiogram reports from two academic centres, we trained our model of classification for predicting left-ventricle ejection fraction (LVEF) categories: abnormal EF (EF < 50%) vs. normal on 25 948 studies. We validated the model on 8110 paired chest CT and echocardiogram results from a separate institution. The model achieved an area under the receiver operating characteristic (AUROC) curve of 0.786 on the hold-out test set and 0.762 on external validation to detect an abnormal EF (<50%). Beyond strong predictive performance, the AI model surpassed expert radiologists in both accuracy and efficiency and provided interpretable visualizations highlighting imaging features linked to reduced LVEF. Conclusion In this study, we developed and validated an AI model capable of predicting abnormal LVEF directly from static, non-gated, non-contrast chest CT scans, a novel application for an imaging modality typically used for unrelated indications as a form of opportunistic screening. This technology holds significant promise for early detection of systolic HF, reducing the diagnostic gap, and improving outcomes in asymptomatic HF patients.

Abstract Background Isocitrate dehydrogenase-1 (IDH-1) inhibitor ivosidenib and dual-IDH1/2 inhibitor vorasidenib have demonstrated clinical activity in the treatment of IDH-mutant gliomas. We evaluated the efficacy of vorasidenib in patients with prior exposure to ivosidenib. Methods Retrospective review of patients with IDH-mutant glioma treated with vorasidenib who had prior treatment with ivosidenib. Previous treatments, radiographic response, and adverse events were collected and analyzed descriptively. Results Twenty-nine patients (median age 42, 34% female) were evaluated. Tumor types included IDH-mutant astrocytoma (grade 2 n = 9, 31%; grade 3 n = 3, 10%; grade 4 n = 3, 10%) and oligodendroglioma (grade 2 n = 10, 34%; grade 3 n = 4, 14%). Treatments received prior to ivosidenib included surgical resection (n = 23, 79%), radiation (n = 16, 55%), temozolomide (n = 15, 52%), procarbazine, lomustine, vincristine (PCV, n = 2, 7%), bevacizumab (n = 3, 10%), lomustine (n = 2, 7%), and pembrolizumab (n = 1, 3%). Four patients received additional treatment in between ivosidenib and vorasidenib treatment. Ten of 16 (63%) patients who experienced disease progression on ivosidenib achieved stable disease and remain on vorasidenib, while 6 (37%) had continued progression. Eleven patients with stable disease on ivosidenib transitioned to vorasidenib following FDA approval and remained without progression. Two patients who transitioned to vorasidenib due to ivosidenib-related adverse effects (diarrhea and fatigue) experienced symptom resolution and maintained disease stability. Conclusions Vorasidenib demonstrated clinical efficacy in patients with IDH-mutant gliomas previously treated with ivosidenib. Notably, stable patients who transitioned maintained disease stability, while some of those with progressive disease achieved stabilization with vorasidenib. These findings support vorasidenib as a viable therapeutic option following ivosidenib exposure.
