Abstract Importance and Objective Upadacitinib, an oral, reversible Janus kinase inhibitor, is approved for the treatment of moderate-to-severe Crohn’s disease (CD). Limiting corticosteroid exposure is an important goal in treating CD. This posthoc analysis evaluated the corticosteroid-sparing effects of upadacitinib in patients with CD. Design and Setting This study included pooled data from two phase 3, multicenter, double-blind induction trials and one maintenance trial. Randomization was stratified by corticosteroid use at induction baseline, with a mandatory corticosteroid taper starting at induction week 4. Efficacy was evaluated by baseline corticosteroid use and by achieving corticosteroid-free outcomes through year 2 of maintenance therapy. Safety was also assessed. Results At baseline, 34.7% (234/674) and 35.7% (124/347) of upadacitinib 45 mg and placebo-treated patients were taking corticosteroids, respectively. At induction week 12 and maintenance week 52, higher rates of upadacitinib-treated patients were corticosteroid-free among all patients and among patients with baseline corticosteroid use compared with placebo; upadacitinib-treated patients achieved higher rates of corticosteroid-free outcomes, compared with placebo, including corticosteroid-free clinical remission (stool frequency/abdominal pain score [SF/APS]: 42.7% vs 16.1%; CD activity index [CDAI]: 41.2% vs 23.4%) and corticosteroid-free endoscopic response (37.0% vs 8.1%), with similar results observed among responders to upadacitinib induction therapy at maintenance week 52. Corticosteroid-free outcomes were sustained through year 2 of maintenance therapy. The safety profile was similar to the overall population, with no new safety risks identified. Conclusions and Relevance The results from pivotal studies demonstrated that upadacitinib effectively induced early and sustainable corticosteroid-free clinical remission with a manageable safety profile in patients with moderate-to-severe CD.

Abstract Perioperative low cardiac output syndrome (LCOS) remains a significant complication in adult cardiac surgery, contributing to substantial morbidity, prolonged intensive care, and increased mortality. Its incidence is expected to rise further due to the evolving complexity of referred surgical patients, often characterised by advanced age, multiple comorbidities, challenging anatomy, and impaired haemodynamics. Despite advances in pharmacological and perioperative care, outcomes for high-risk patients have not shown significant improvement, prompting interest in temporary mechanical circulatory support (tMCS) as a proactive strategy. This Expert Consensus Document from the European Association for Cardio-Thoracic Surgery (EACTS) presents the first dedicated guidance on the pre-emptive use of tMCS in high-risk adult cardiac surgical patients. Developed by a multidisciplinary task force, it emphasises structured risk stratification, early initiation, and individualised device management informed by interdisciplinary Heart Team discussions. The document proposes clinical pathways for patient selection, defines criteria for tMCS initiation, and provides practical algorithms for various scenarios, including advanced heart failure, cardiogenic shock, and post-cardiotomy LCOS. It reviews the current evidence on available tMCS devices, such as intra-aortic balloon pumps, microaxial flow pumps, veno-arterial extracorporeal life support and hybrid strategies, and addresses perioperative care, intensive care unit protocols, ethical considerations, as well as informed consent and support withdrawal. Despite promising results, substantial knowledge gaps remain, including long-term outcome data, device selection criteria, and cost-effectiveness analyses. This consensus aims to support clinical decision-making, standardise practice, and stimulate research to improve outcomes in a growing population of high-risk surgical patients.

Background. The spirometric response to standard-of-care (SOC) immunosuppressive therapy for the management of bronchiolitis obliterans syndrome (BOS) has been sparsely reported in the literature. Data from a Medicare-approved Registry were analyzed to characterize the effectiveness/durability of a wide range of SOC interventions to manage the decline of lung function and to validate the study spirometric criteria for initiation of rescue therapy. Methods. Lung transplant recipients with refractory BOS at 21 US collaborating centers were enrolled in the Registry. Data included both nonspirometric (eg, demographic, Immunosuppressive Regimens for management of BOS) and spirometric parameters (ie, forced expiratory volume in 1 s [FEV 1 ] measurements and derived indices). The utility of study FEV 1 criteria for treatment (ie, statistically significant rate of FEV 1 decline >30 mL/mo) was evaluated by comparing the spirometric course between participants who met or did not meet this criterion. Results. Only 21% of participants treated with SOC therapy had >50% decrease (76 ± 25% decrease) in the rate of FEV 1 decline. Although 51% of participants had a partial response (rate of FEV 1 decline decreased on average 71%), 49% of participants had a substantial increase (mean increase 224%). The FEV 1 criterion for treatment was able to identify 19% of participants (48/258) who achieved durable stabilization (ie, nonsignificant rate of FEV 1 <30 mL/mo) with SOC therapy. Conclusions. Patients with BOS have a widely variable response to SOC therapy. Our findings support the use of FEV 1 rate of decline to assess response to SOC therapy and to ensure appropriate assignment of participants with refractory BOS to rescue therapy treatment cohorts.

Abstract INTRODUCTION In multicenter Alzheimer's disease studies, amyloid positron emission tomography (PET) visual reads are typically performed centrally by a few experts. Incorporating a broader reader network enhances scalability and generalizability. METHODS Ten neuroimaging experts from eight Alzheimer's Disease Research Centers (ADRCs) visually read 180 amyloid PET scans (30 scans and 15 duplicate scans for each of four tracers, imaged across a wide variety of scanners), using preferred reading software without anatomical imaging or quantitation. Scans were classified as elevated or non‐elevated per tracer‐specific criteria. Inter‐ and intra‐rater agreement was assessed. RESULTS Inter‐rater agreement was substantial (Fleiss’ κ = 0.78), with full consensus on 69% of scans. Inter‐rater reliability was substantial to perfect across tracers (Fleiss’ κ = 0.70–0.87). Intra‐rater agreement was substantial to perfect (Cohen's κ = 0.79‐1). Scans with intermediate (10–40 Centiloid) quantitation had lower reader agreement. DISCUSSION A multicenter expert network achieved substantial agreement classifying amyloid PET scans. These scans provide a standard for reader training and reliability assurance in future studies. Highlights Calibration methods ensure reliable amyloid positron emission tomography (PET) visual reads across multiple raters. Substantial agreement is possible across readers using their preferred tools. Agreement is also substantial regardless of the amyloid PET tracer used. Scans with intermediate (10–40 Centiloid) quantitation have lower reader agreement. The calibration set will become a training tool for amyloid PET visual read studies.

Objective The primary lateral sclerosis ( PLS ) consensus diagnostic criteria and functional rating scale ( PLSFRS ) were recently established to facilitate and optimize future PLS clinical trials. We examined the trajectory of the PLSFRS and other functional outcome measures and biomarkers in the PLS Natural History Study ( PLS NHS ) to understand their performance in this prospective cohort. Methods The PLS NHS is a prospective, longitudinal, multicenter study of people living with PLS in different diagnostic categories: early (disease duration <2 years); probable (2–4 years); and definite PLS (4–15 years). PLSFRS scores and other functional outcome measures were collected at baseline, 3‐, 6‐, 9‐, and 12‐month follow‐up visits. Baseline characteristics were compared between the groups. The slopes of the PLSFRS and other functional outcome measures over 12 months were examined in the overall cohort and subgroups using linear mixed‐effect models. The associations between baseline characteristics and the rate of PLSFRS decline were analyzed with linear regression models. Results A total of 76 participants were included: early (n = 6); probable (n = 26); and definite (n = 44) PLS . Baseline PLSFRS total scores were highest in the early PLS group, followed by the probable and definite PLS groups. In the overall cohort, the PLSFRS total score declined by 0.33 points/month (95% confidence interval [0.27–0.39], adjusted p < 0.05). The rate of decline was steepest in the early PLS group, followed by the probable and definite PLS groups. Baseline neurofilament light chain level was associated with the rate of PLSFRS decline over 1 year ( p = 0.001). Interpretation In PLS, the rate of functional decline, as measured by the PLSFRS total score, is faster during the early phase of the disease. Neurofilament light might serve as a prognostic biomarker in PLS. ANN NEUROL 2026;99:418–428

Background: Ankle arthroscopy (AA) is a commonly used operative technique to diagnose and treat a variety of intraarticular pathologies of the ankle joint. In AA, 2 portals are commonly established to achieve visualization of the joint: the anteromedial (AM) and anterolateral (AL) portals. However, the superficial peroneal nerve (SPN) runs near the anterolateral portal site; thus, creation of the AL portal is associated with neuropraxic injuries to the SPN. When AA is combined with additional procedures, such as a Brostrom-Gould ligament repair or open reduction internal fixation (ORIF), the use of a direct lateral incision is required. We present a novel approach to combining AA with lateral adjunct procedures which avoids creation of the AL portal; the AM portal and lateral incision are used for instrumentation instead. The primary objective of this study is to compare complication rates, such as SPN injury, between the lateral incision (LI) approach and conventional arthroscopy plus a lateral incision approach. Methods: Following IRB approval, a retrospective chart review was conducted spanning a time frame from January 2020 to October 2024. Patients were included if they underwent AA plus either a Brostrom-Gould repair or ORIF (AA+) or if they underwent AA plus adjunct procedures using the lateral portal instrumentation method (LI). Ninety-four patients were initially identified; 2 were excluded per criteria. Demographic information, intraoperative details, and any postoperative complications or reoperations were recorded. Descriptive statistics were used to describe demographics and operative data, and 2-tailed Student t tests were used to identify statistical differences between group metrics. Results: Ninety-two patients were included in the study. No statistical differences were observed between cohorts in either of the intraoperative metrics considered (procedural duration and tourniquet duration; P = .44 and .89, respectively). In addition, complication and reoperation rates were not statistically different between the LI and AA+ groups ( P = .94 and .40, respectively). The rate of SPN neuropathy or neurapraxia were also compared between groups, resulting in no statistical differences ( P = .37). Conclusion: In this retrospective cohort study, we observed no differences when only anteromedial and lateral portals are used for an ankle arthroscopy with adjunct procedures compared with the traditional 3-incision approach. We hypothesize that instances of infection or wound dehiscence would decrease given a large enough cohort because of the creation of 1 fewer portal. However, given the small, underpowered sample, we cannot determine whether the lateral approach alters complication risk; larger multicenter studies are needed. Level of Evidence: Level III, retrospective cohort study.

BACKGROUND. We developed a prospective, multicenter “registry” to evaluate the effect of extracorporeal photopheresis for lung transplant recipients who develop chronic lung allograft dysfunction (CLAD) with the bronchiolitis obliterans syndrome (BOS) phenotype (CLAD/BOS) and who are refractory to conventional standard-of-care therapy. METHODS. Data from 258 lung transplant recipients enrolled in the Registry between April 2015 and April 2022 were included in this analysis. All recorded parameters (eg, demographics), including forced expiratory volume in 1 s (FEV1) measurements and indices (FEV1% baseline, FEV1 rate of decline) at several time periods, were included in multivariate linear/logistic and Kaplan-Meier analyses to evaluate potential associations with survival. RESULTS. Mortality at 6 and 12 mo after CLAD/BOS diagnosis was 5% and 14%, whereas mortality at 6 and 12 mo after enrollment was 15% and 26%, respectively. The primary cause of death in the cohort was respiratory failure or graft failure (74%). Rate of FEV1 decline (log) at enrollment was independently associated with survival (log days) from CLAD/BOS diagnosis and enrollment (r = 0.55 and r = 0.3, respectively). The rates of FEV1 decline among survivors were lower (–77 ± 89 mL/mo) compared with nonsurvivors (–148 ± 155 mL/mo) at 6 mo after enrollment (P = 0.0001). CONCLUSIONS. The rate of FEV1 decline quantified using at least 5 FEV1 measurements is a robust surrogate outcome. We plan to use these findings to revise our randomized controlled trial to facilitate risk adjustment using FEV1 rate of decline strata at enrollment and as a scientifically valid surrogate for outcome.
