Background: Polydactyly surgery rates and trends are poorly characterized. The purpose of this study was to characterize national pediatric polydactyly management by examining operative and procedural trends over time, evaluating timing of treatment, identifying factors associated with interventions, and comparing costs and complications. Methods: We used the PearlDiver national administrative claims database to identify pediatric patients aged 18 and under with a diagnosis of polydactyly (2010-2023). We analyzed patients who received procedures coded as surgical correction or suture ligation, then characterized rates and factors associated with each intervention, and investigated postoperative complication rates. Results: Of 42 543 polydactyly patients, 3880 patients (9.1%) underwent surgery, and 5612 patients (13.2%) underwent procedures coded as suture ligation. Over the past decade, the incidence of polydactyly diagnosis and surgery has decreased, while rates of procedures coded as suture ligation have not changed significantly. In 2010, 12.0% of patients underwent surgery, compared to 7.3% in 2020. Patients of ages 1 to 2 years comprised the greatest proportion of the population who underwent surgical operations at 1729 patients (36.0%), and patients of ages 0 to 1 year comprised the greatest proportion of the population who underwent suture ligations at 3327 patients (51.0%) ( P < .001). Younger age at diagnosis and higher comorbidity index were associated with a greater likelihood of surgery, while greater mean family income was associated with a lower likelihood. Among treatment categories, surgery was associated with greater 1-year and total payer-reimbursed costs ( P < .05). Conclusions: We observed a declining incidence of pediatric polydactyly and polydactyly surgery. These findings may inform future guideline development and discourse for pediatric hand care.

Abstract Globally, gastric adenocarcinoma is the fourth leading cause of cancer mortality and a major cancer disparity in the United States. Chemoprevention strategies are lacking for high-risk individuals with gastric premalignant conditions (GPMC). Curcumin, the principal curcuminoid in turmeric, exerts immunomodulatory effects in the epithelium and against Helicobacter pylori, and studies suggest chemoprevention potential. We conducted a double-blind, phase IIa randomized controlled trial in high-risk populations in Puerto Rico and Honduras. We investigated the utility of a bioavailable formulation of curcumin (Meriva) among individuals with H. pylori–negative GPMC, specifically, multifocal atrophic gastritis (MAG) or gastric intestinal metaplasia (GIM). Patients were 1:1 randomized to 1,000 mg Meriva daily or placebo for a 6-month intervention with endoscopy at baseline and 6 months. Outcomes included assessment of epithelial cytokine and chemokine levels, histology, and DNA damage as assessed by γ-H2AX phosphorylation IHC. Of the 110 subjects screened, 50 participants were randomized, and 48 completed the trial. A significant reduction in gastric mucosal IL1β levels from baseline in the gastric body, the primary endpoint, was observed in the Meriva group (P = 0.032). Changes in epithelial IL8, TNFα, and inducible protein 10 levels and gastric mucosal histology and DNA damage (secondary endpoints) were similar between arms. Curcumin (Meriva) was safe, well-tolerated, and showed potential as a curcuminoid chemoprevention agent in H. pylori–negative patients with GPMC. A potential reduction in gastric inflammation as measured by gastric mucosal IL1β levels was observed. Further studies are warranted, including studies in H. pylori–positive individuals, based upon the curcuminoid direct effects on H. pylori. Prevention Relevance: Gastric adenocarcinoma is a leading cause of cancer mortality worldwide. Chemoprevention candidates for GPMCs are limited. This randomized phase IIa trial evaluated a bioavailable curcumin formulation in high-risk individuals with MAG and GIM. The results support further study of curcuminoids for gastric cancer risk reduction. See related Spotlight, p. 387 See related article by Morgan et al., p. 391

Background Recent studies have disputed the association between bisphenol A (BPA) and endometriosis. This updated meta-analysis was conducted to investigate the impact of BPA exposure on endometriosis. Methods This study evaluated BPA exposure and endometriosis risk, analyzing studies from Web of Science, PubMed, Embase, Cochrane Library, and Chinese databases (CNKI, CBM, Wanfang, VIP) through August 2025. Methodological quality was assessed via the Newcastle-Ottawa Scale (NOS) and the Agency for Healthcare Research and Quality Tool (AHRQ). Heterogeneity was quantified using I 2 statistics. Pooled odds ratios (ORs) and 95% CIs were calculated using fixed- or random-effects models according to heterogeneity. Subgroup analysis, sensitivity analysis, and publication bias assessment were supplemented to validate the overall finding. Results Seven studies comprising 2,488 participants were included in quantitative synthesis. The meta-analyses demonstrated that BPA exposure was associated with a statistically significant increase in endometriosis risk (OR = 1.36, 95% CI = 1.13–1.63, p = 0.008). Additionally, subgroup analysis indicated that BPA exposure may further elevate endometriosis risk in cases with different regions, populations, and measurement methods. Sensitivity analysis confirmed that the results of these meta-analyses were relatively robust. No publication bias was detected.

Abstract INTRODUCTION : Despite expanding use of plasma biomarkers for Alzheimer's disease (AD), minimal examination has been undertaken in early‐onset AD (EOAD). Prior analyses assessed criterion and convergent validity of common plasma biomarkers in a well‐characterized sample with sporadic EOAD. METHODS : Plasma amyloid beta (Aβ) 42/40, tau phosphorylated at threonine 231 (p‐tau231), glial fibrillary acidic protein (GFAP), and neurofilament light change (NfL) levels were obtained for 189 EOAD, 52 early‐onset non‐AD (EOnonAD), and 83 cognitively normal (CN) participants. Diagnostic group differences, convergence with imaging biomarkers, and the capacity to predict specific cognitive domains were investigated. RESULTS : After controlling for cognitive status, EOAD participants exhibited more pathologic levels of Aβ42/40, p‐tau231, and GFAP relative to EOnonAD participants. However, NfL displayed the greatest sensitivity to non‐amnestic cognitive impairment across the sample. DISCUSSION : These results establish criterion and convergent validity of plasma biomarkers in sporadic EOAD and highlight complementary roles that AD‐specific and non‐specific plasma markers may play across the course of AD care.

Abstract INTRODUCTION Naturalistic driving provides real‐world behavioral indicators of early cognitive and functional changes. This study integrated naturalistic driving GPS trajectories collected from in‐vehicle sensors with points of interest (POIs) to quantify daily environmental engagement among older adults who were cognitively normal at enrollment. METHODS Data from 438 participants enrolled in the Driving Real‐world in‐Vehicle Evaluation System Project were used to generate daily POI share vectors and model latent engagement patterns using a logistic‐normal hidden Markov model (HMM). Thirteen latent states described distinct modes of environmental interaction. From each participant's inferred state sequence, we derived mobility features – state occupancy, dwell time, transition entropy, and self‐transition probability – and examined their differences across clinical status groups and associations with Preclinical Alzheimer's Cognitive Composite (PACC) performance. RESULTS Transition entropy and several state‐specific occupancy and dwelling metrics differed across clinical groups, but none of the mobility features were significantly associated with PACC scores. DISCUSSION Mobility‐derived behavioral features differentiate clinical status groups and may reflect early functional changes preceding cognitive decline.

Background Large vessel occlusion (LVO) stroke is associated with a high risk of permanent disability. There are no reliable tools providing periprocedural information on clot characteristics, such as composition and length, that may impact first pass effect, which has been shown to improve functional outcomes. In the first study of a novel technology, we evaluated whether the Clotild Smart Guidewire System (Clotild), an impedance-based device, can provide in situ information on clot characteristics during a mechanical thrombectomy procedure. Methods This is the first-in-human, international, multicentric, single-arm trial involving LVO stroke patients. Of 45 enrolled subjects, 41 constituted the safety population; 39 was the per protocol population, of which 26 subjects with complete impedance data comprised the performance population. The latter was divided into development (11 subjects) and validation (15 subjects) populations for prediction model development and assessment. The safety endpoint assessed Clotild-related intracranial vessel perforation/dissection. Performance endpoints evaluated Clotild’s ability to perform classification of impedance measurements distinguishing substantial versus negligible local content in red blood cells (RBCs) and platelets, to detect the arterial wall and the distal end of the clot. Results The safety endpoint was met in all subjects. Performance analysis comparing the agreement between Clotild’s output and impedance experts’ readings showed an area under the receiver operating characteristic curve (AUC) of 0.97 (95% CI 0.93 to 0.99) for RBC, and 0.94 (95% CI 0.89 to 0.98) for platelet clot composition. Regarding detection, Clotild’s performance showed an AUC of 0.69 (95% CI 0.59 to 0.77) for the arterial wall, and 0.83 (95% CI 0.59 to 1.00) for the distal end of the clot. Conclusions Clotild was proven safe to acquire impedance data and to provide information on in situ clot characteristics in large vessel occlusions.

Abstract Background Coccidioidomycosis is the most prevalent endemic mycosis in the United States. Diagnosis of coccidioidomycosis can be challenging due to limitations of conventional diagnostics. Detection of fungal plasma cell-free DNA (cfDNA) is a novel noninvasive testing modality for the diagnosis of invasive fungal disease. In this study, we characterized the performance of Coccidioides plasma cfDNA polymerase chain reaction (PCR). Methods A retrospective study was conducted in patients with suspected coccidioidomycosis who underwent plasma cfDNA PCR testing and conventional fungal testing for Coccidioides immitis and Coccidioides posadasii. Patients were categorized per the EORTC/MSGERC case definitions as proven or probable for sensitivity analyses and no coccidioidomycosis for specificity analyses. Results Overall, 362 plasma samples from unique patients were included in this study. The overall sensitivity, specificity, and positive- and negative-predictive values of Coccidioides plasma cfDNA PCR at 0.04% prevalence were 57.5% (27/47; 95% CI, 42.2%–71.7%), 100% (315/315; 95% CI, 98.8%–100%), 100% (95% CI, 87.2%–100%), and 100% (95% CI, 100%–100%), respectively. The sensitivity was 33.3% (2/6; 95% CI, 4.3%–77.7%) in patients with pulmonary focal disease, 66.7% (14/21; 95% CI, 43.0%–85.4%; P≥.05) in patients with pulmonary multifocal disease, and 52.6% (10/19; 95% CI, 39.6%–77.9%; P≥.05) in patients with disseminated coccidioidomycosis. In patients with concurrent antigen results, the sensitivity of cfDNA PCR was 58.3% (14/24; 95% CI, 39.6%–77.9%) compared with 37.5% (9/24; 95% CI, 18.8%–59.4%; P≥.05) for antigen. Conclusions Coccidioides plasma cfDNA PCR is modestly sensitive but highly specific, which can be useful for rapid and noninvasive diagnosis of coccidioidomycosis.

Abstract Aims Mitral valve prolapse (MVP) is a common valvular disorder associated with ventricular arrhythmias (VAs) in a subgroup of patients, known as arrhythmic MVP (AMVP). Arrhythmic MVP patients with malignant VAs typically receive an implantable cardioverter-defibrillator (ICD) for secondary prevention. However, data regarding the incidence of appropriate ICD therapy and the type of arrhythmia recurrence in this population remain scarce. This study aimed to evaluate the incidence of appropriate ICD therapies and type of arrhythmia recurrence in AMVP patients with an ICD implanted for secondary prevention. Methods and results A systematic literature search was conducted in PubMed/MEDLINE and EMBASE databases until January 2025. Studies reporting the incidence of appropriate ICD therapy in AMVP patients were included. A total of 9 studies met the inclusion criteria, resulting in 166 AMVP patients with ICDs for secondary prevention. The mean age was 41.8 years, with 55.8% of patients being female. Over a weighted mean follow-up of 4.9 ± 3.1 years, 34.9% [95% confidence interval (CI): 28.1–42.5] of the patients experienced recurrence of VA. The pooled incidence of appropriate ICD therapies during follow-up was 8.1 per 100 person-years (95% CI: 5.6–10.5, I2: 11.7%). Regarding the type of arrhythmic recurrence, the majority of arrhythmias (53.8%, 95% CI: 44.3–63.0%) were in the form of ventricular fibrillation or polymorphic ventricular tachycardia (VT), while the remaining arrhythmias were reported as monomorphic VT. Among 67 ventricular arrhythmic episodes reported in 7 studies with available data, 65 required shock therapy, corresponding to a shock proportion of 97.0% (95% CI: 89.6–99.6%). Conclusion Arrhythmic MVP patients with ICDs for secondary prevention exhibit a high risk of recurrent arrhythmias, with recurrences in the form of polymorphic VA occurring in more than half of the cases.
