Objective Mycophenolate mofetil (MMF) can stabilize or improve lung function in systemic sclerosis–related interstitial lung disease (SSc‐ILD). We hypothesized that combining MMF with pirfenidone (PFD) would produce a significantly more rapid and/or greater improvement in lung function. Methods A randomized (1:1), double‐blind, placebo (PLA)‐controlled phase 2 trial was conducted in SSc‐ILD in which patients received PFD or PLA (801 mg three times daily) along with MMF (1,500 mg twice daily) for 18 months. The primary outcome was change in percent predicted forced vital capacity (FVC‐%). Linear mixed‐effects models assessed treatment differences in a modified intention‐to‐treat population. Results Only fifty‐one of 150 intended subjects (34%) were randomized (MMF+PLA, n = 24; MMF+PFD, n = 27). The FVC‐% improved from baseline to 18 months by 2.24 ± 1.35 (least‐squares mean [LSM] ± SEM) in the MMF+PLA group and 2.09 ± 1.28 in the MMF+PFD group (LSM treatment difference −0.14; P = 0.93). Median time to achieve a ≥3% improvement in FVC‐% was numerically faster in the MMF+PFD versus MMF+PLA group (12.3 vs 17.8 months, respectively), but the difference was not significant ( P = 0.33). For secondary outcomes, only the change over 18 months in the Patient‐Reported Outcomes Measurement Information System 29‐item physical function score, favoring MMF+PFD, reached statistical significance ( P = 0.04). Although other related patient‐reported outcomes (PROs) numerically favored the MMF+PFD group, as did quantitative high‐resolution computed tomography measures of ILD, the differences between groups did not reach statistical significance. Early withdrawals from study medication and adverse events of special interest were numerically greater with MMF+PFD (n = 8 vs 2 and n = 20 vs 7, respectively). Conclusion In this underpowered study, there was no statistically significant treatment difference in overall change in FVC‐% between groups. MMF+PFD was not as well tolerated as MMF+PLA.

Abstract Objectives Pivotal trials have established the effectiveness of the Responsive Neurostimulation System (RNS® System) in treating focal epilepsy. In clinical trials, depth leads were primarily used to treat mesial temporal seizure onsets while cortical strip leads were used to treat neocortical seizure onsets. Here, we systematically analyze the safety and efficacy of stereoelectroencephalography (sEEG)‐guided depth leads to provide responsive stimulation to neocortical gray matter. Methods Patients were stratified as strong responders (>median cohort seizure reduction %), weak responders (>0% and ≤median cohort seizure reduction %), and anti‐responders (≤0%) based on percent seizure reduction at 1 year post‐implant (1‐Y). Pre‐operative T1‐weighted magnetic resonance imaging and post‐operative computed tomography images were merged, and the Euclidean distance between the sEEG epileptic focus (sEEG‐EF) and the nearest RNS System depth lead contacts was calculated. Results A total of 87 depth leads were implanted in 55 patients across neocortical brain regions. The median reduction in clinical seizures improved from 66.7% at 1‐Y to 77.5% at long‐term follow‐up (LTFU: 2.35 ± 0.95 years), with 10 patients (18.2%) achieving complete seizure freedom. Seven patients (12.7%) experienced six serious adverse events. At 1‐Y, shorter Euclidean distance between the sEEG‐EF and RNS System depth leads predicted improved seizure outcome in strong responders ( β = −0.84, p = 0.008) but not in weak responders ( β = 0.21, p = 0.9) or anti‐responders ( β = −20.34, p = 0.11). At LTFU, there was no significant relationship between Euclidean distance and seizure reduction in strong responders ( β = 0.77, p = 0.18), weak responders ( β = 2.05, p = 0.54), or anti‐responders ( β = 0.24, p = 0.99). Exploratory analyses at 1‐Y showed nominal associations between older age ( ρ = 0.32), longer epilepsy duration ( ρ = 0.27), and non‐mesial temporal sEEG‐EFs and greater seizure reduction; however, none survived Bonferroni correction (adjusted α = 0.0027; all post‐correction p > 0.0027), and no associations were observed at LTFU. Significance In this series, neocortical depth leads for RNS therapy had favorable safety and efficacy and proximity to the sEEG‐EF drove initial outcomes for strong responders to RNS therapy. Plain Language Summary In this multi‐center study, patients with difficult‐to‐treat seizures received brain‐responsive stimulation using a device called responsive neurostimulation (RNS), which delivers small electrical pulses to reduce seizures. We focused on patients treated with electrodes placed in the brain's outer regions (the neocortex) and guided by a mapping procedure called sEEG. On average, patients had their seizures cut by two‐thirds after one year and by more than three‐quarters with longer follow‐up, with about one in five becoming seizure‐free. The treatment was safe, and closer electrode placement to the seizure source helped explain early—but not long‐term—improvements.

Abstract Objective Dravet syndrome (DS) is a developmental and epileptic encephalopathy characterized by drug‐resistant seizures and developmental slowing. Although cognitive and executive function deficits have been described, their early trajectory is not well understood. Methods The prospective ENVISION natural history study (NCT04537832) assessed cognitive, executive, and adaptive function in children younger than 5 years of age with SCN1A + DS every 6 months for up to 2 years using Bayley Scales of Infant and Toddler Development, 3rd Edition (BSID‐III), Wechsler Preschool & Primary Scale of Intelligence, 4th Edition (WPPSI‐IV), Vineland Adaptive Behavior Scales, 3rd Edition (VABS‐3), Behavior Rating Inventory of Executive Function – Preschool Version (BRIEF‐P), and Pediatric Evaluation of Disability Inventory (PEDI). Results Fifty‐eight children were enrolled, with 47% younger than age 2 years. At least 80% of children did not achieve age‐appropriate milestones. Mean BSID‐III Cognitive raw scores increased minimally, with age‐equivalent gains of only 3 months over 1.5 years. Mean Cognitive Composite scores declined significantly by Month 12 (from 81.6 to 72.2; change: –11.0, 95% confidence interval [CI]: −15.3 to −6.8), signaling a widening gap compared with neurotypical development. Executive function worsened, with mean BRIEF‐P Global Executive Composite T‐scores increasing by 3.2 points/year. For some participants, scores were 5 standard deviations (SD) above the normative mean, reflecting abilities profoundly below age expectations (bottom .00003% of the population). Adaptive functioning worsened, with mean VABS‐3 Adaptive Behavior Composite decreasing from 78.7 to 68.1 over 1.5 years (change: –9.0, 95% CI: −11.9 to −6.1) and greater decline among children <2 years at enrollment, with scores decreasing by ~15 points (1 SD). Over half of children >3 years could not remove clothing independently; and when placed on a toilet, 48% could not use it. Significance Infants and young children with SCN1A + DS show significant and progressive developmental slowing across several domains, highlighting urgent need for therapies to mitigate the devastating impact on individuals and families.

ABSTRACT Background Adolescents with youth‐onset type 2 diabetes (YO‐T2D) have an increased risk for cardiometabolic complications. The impact of vertical sleeve gastrectomy (VSG) on fat distribution and cardiac morphology/function in YO‐T2D is unknown. Objectives To evaluate changes in body composition, abdominal and cardiac fat depots, and cardiometabolic health in adolescents with YO‐T2D undergoing VSG. Methods Anthropometrics, labs and imaging were used to assess participants pre‐surgery and 3–12 months post‐surgery. MRI quantified pericardial (PAT), epicardial (EAT), subcutaneous (SAT) and visceral adipose tissue (VAT), hepatic fat fraction (HFF) and cardiac morphology/function. Mixed‐effects models assessed longitudinal changes. Results By 12 months, weight decreased from 134.3 ± 5.1 to 103.3 ± 5.2 kg, VAT 1943 ± 148 to 1248 ± 150 cm 3 , HFF 23.2% ± 2.3% to 5.3% ± 2.3% and PAT and EAT by 27% and 33% (all p < 0.01). Homeostatic model assessment of insulin resistance (HOMA‐IR) improved (7.8 ± 1.2 to 1.7 ± 1.2 [ p < 0.01]). BMI, SAT, resting heart rate (RHR), left ventricular (LV) mass and cardiac output (CO) also decreased (all p < 0.05). VAT decreases correlated with decreases in HFF ( r = 0.70, p = 0.01), HOMA‐IR ( r = 0.60, p = 0.04) and CO ( r = 0.70, p = 0.03). HFF decreases correlated with decreases in BMI ( r = 0.70, p = 0.03), HOMA‐IR ( r = 0.90, p < 0.001), RHR ( r = 0.90, p = 0.002), CO ( r = 0.80, p = 0.007) and LV mass ( r = 0.70, p = 0.02). Conclusions VSG reduces ectopic and regional fat and improves associated insulin sensitivity and cardiac health in adolescents with YO‐T2D.

Abstract Background Computational phenotyping from electronic health records (EHRs) is essential for clinical research, decision support, and quality/population health assessment, but the proliferation of algorithms for the same conditions makes it difficult to identify which algorithm is most appropriate for reuse. Objective To develop a framework for assessing phenotyping algorithm fitness for purpose and reuse. Fitness for Purpose Phenotyping algorithms are fit for purpose when they identify the intended population with performance characteristics appropriate for the intended application. Fitness for Reuse Phenotyping algorithms are fit for reuse when the algorithm is implementable and generalizable—that is, it identifies the same intended population with similar performance characteristics when applied to a new setting. Conclusions The PhenoFit framework provides a structured approach to evaluate and adapt phenotyping algorithms for new contexts increasing efficiency and consistency of identifying patient populations from EHRs.

Background: Orthopaedic sports medicine fellowships are highly competitive, yet objective data defining characteristics of successful applicants remain limited. Hypothesis: It was hypothesized that greater academic productivity, top-tier residency training, and certain demographic factors would be associated with matching into a top-ranked orthopaedic sports medicine fellowship. Study Design: Cross-sectional study. Methods: We retrospectively reviewed applicants who matched into one of the top 10 orthopaedic sports medicine fellowships from 2020 to 2025, as identified by previous applicant preference rankings. Applicant data were obtained from publicly available sources and verified by 2 independent reviewers. Variables included sex, degree type, residency program ranking, geographic region, and research productivity (total publications, primary publication count, H-index, and sports-related publications). Multivariate logistic regression assessed predictors of matching into top 5 versus 6th- to 10th-ranked programs. Results: Among 226 matched applicants, 87.7% were male and 99.1% held a doctorate in medicine degree. The mean total publication count was 12.4, mean H-index was 8.2, and 30.5% trained at a top 20 orthopaedic residency. Applicants matching into top 5 programs had significantly higher research metrics than those in the 6th- to 10th-ranked programs: total publications (20.1 vs 4.7), primary publication count (6.2 vs 1.6), and sports-related publications (11.4 vs 1.9). On regression analysis, total publications, H-index, and residency ranking were independent predictors of matching into a top 5 program. Conclusion: Matching into a top orthopaedic sports medicine fellowship is associated with higher academic productivity and training at a top-tier residency program.

Introduction: Patients with transthyretin amyloid cardiomyopathy (ATTR-CM) typically have low serum transthyretin (sTTR) levels, worsening heart failure, and increased mortality. A recent study has shown the association of sTTR levels ≥20mg/dL with reduced risk of all-cause mortality and cardiovascular mortality (CVM). It has also been shown that regardless of baseline sTTR level, greater increases in sTTR levels are associated with greater improvements in cardiovascular outcomes. Acoramidis, a near-complete (≥90%) TTR stabilizer, demonstrated a rapid and sustained increase from baseline in sTTR by Day 28 and reduced risk of cardiovascular outcomes in patients with ATTR-CM. Hypothesis: Acoramidis-mediated early increase in sTTR levels ≥20 mg/dL (lower limit of normal) at Day 28 reduces risks of CVM and cardiovascular-related hospitalizations (CVH) in patients with ATTR-CM. Methods: Analyses were conducted in the ATTRibute-CM modified intention-to-treat (mITT) population (acoramidis: 409; placebo: 202). The sTTR concentrations (normal range is 20-40 mg/dL) were assessed using an immunoturbidimetric method (Abbott ARCHITECT system) in a central laboratory. The proportion of participants with sTTR levels below normal at baseline and Day 28 were determined. The relationship between sTTR levels <20 or ≥20 mg/dL, at Day 28 across the pooled acoramidis and placebo treatment groups, and subsequent risk of CVM and of CVH over 30 months were analyzed using a stratified log-rank test. Results: At baseline about 25% of study participants had sTTR levels below normal in both treatment groups. At Day 28, less than 2% of participants had sTTR levels <20 mg/dL in the acoramidis arm compared with 26% in the placebo arm ( Table 1 ). When acoramidis and placebo treatment groups were pooled based on sTTR levels <20 or ≥20 mg/dL at Day 28, participants with sTTR ≥20 mg/dL were associated with a lower risk of the composite endpoint of CVM or first CVH at Month 30 in comparison with <20 mg/dL ( p <0.0001) ( Figure 1A ). Comparable findings were observed for the individual components (CVM, first CVH) ( Figure 1B and C ). Conclusion: Across treatment groups, sTTR levels above normal range (≥20 mg/dL) at Day 28 were associated with a lower risk of cardiovascular outcomes at Month 30, when compared with sTTR levels below normal range (<20 mg/dL). Thus, these observations demonstrate that higher sTTR levels over time may have the potential for clinical benefits in both CVM and CVH.

Introduction: Acoramidis, an oral transthyretin (TTR) stabilizer achieving near-complete (≥90%) TTR stabilization, is now approved in the USA, EU, Japan, and UK for the treatment of TTR amyloid cardiomyopathy (ATTR-CM). In the 30-month phase 3 ATTRibute-CM study, acoramidis reduced all-cause mortality (ACM) or first cardiovascular-related hospitalization (CVH) vs placebo. Through Month 42 (M42) of the open-label extension (OLE; 30 months ATTRibute-CM + 12 months OLE), the clinical benefit of acoramidis was sustained, resulting in a 36% and 43% risk reduction in ACM and ACM/first CVH, respectively, compared with the placebo to acoramidis group Research Question: Are the long-term clinical benefits of acoramidis on ACM and ACM/first CVH in ATTR-CM over 42 months consistent across patient subgroups? Methods: ATTRibute-CM study design has been previously described. At the end of the 30-month double-blind period, patients enrolled into OLE continued acoramidis or switched from placebo to acoramidis; all patients received open-label acoramidis HCI 800 mg BID. Data cut was performed after 12 months in OLE. Subgroup analysis for ACM and ACM/first CVH through M42 were conducted for randomization stratification factors (genotype, NT-proBNP, and eGFR levels) and other pre-specified subgroups. ACM included death due to any cause, cardiac mechanical assist device placement, and heart transplant. CVH included CV hospitalizations (≥24 h) and urgent visits (<24 h) for decompensated heart failure requiring IV diuretics and was adjudicated by an independent Clinical Events Committee. Results: Overall, 389 patients enrolled in the OLE (263 continuous acoramidis and 126 placebo to acoramidis). The analyses of ACM/first CVH ( Figure 1 ) and ACM ( Figure 2 ) through M42 consistently favored patients initially randomized to acoramidis across all patient subgroups, including those based on sex, age, country, ATTR-CM genotype, baseline NT-proBNP, baseline eGFR, NYHA class, and NAC stage. The largest effect size for the reduction in ACM/first CVH (HR <0.50) was observed in the following subgroups: female, non-Caucasian patients, variant ATTR-CM, or NAC stage 2. Conclusions: The long-term benefit of acoramidis was consistently shown in patients initially randomized to acoramidis treatment compared with placebo to acoramidis switch after 30 months across multiple clinically relevant subgroups, underscoring the importance of early initiation of acoramidis to reduce the long-term risk of ACM or CVH.
