Background: Dancers are at risk of femoroacetabular impingement (FAI) owing to supraphysiologic range of motion and associated demands placed on their hips. There remains a paucity of literature on midterm outcomes in dancers who undergo primary arthroscopy and labral repair for FAI. Purpose: To determine the rate of return to dance and patient-reported outcome measures in competitive dancers after hip arthroscopy with labral repair for FAI with minimum 2-year follow-up. Study Design: Case series; Level of evidence, 4. Methods: This study included dancers with FAI undergoing primary hip arthroscopy with labral repair from 2010 to 2022. Patient-reported outcome measures were collected at 2-year minimum follow-up: modified Harris Hip Score (overall, activities of daily living, gait, pain), Hip Outcome Score (activities of daily living, sports-specific subscale), Tegner Activity Scale, visual analog scale for pain, and surgery satisfaction. Patients were evaluated for preoperative radiographic measurements, postoperative return to sport, and revision surgery. Return to dance was evaluated. Results: Thirty-seven dancers were followed for a mean 7.4 years (range, 3.2-12.2) postoperatively (36 female and 1 male; mean ± SD age, 21 ± 7 years; mean body mass index, 23.3 ± 4.5). All outcome scores significantly improved postoperatively as compared with preoperatively ( P ≤ .037). Twenty dancers (71%) returned to dance. Of those who returned to dance, 17 (85%) returned to sport at the same or higher level as compared with the preoperative level. At final follow-up, 45% of dancers who initially returned to dance continued to dance. Of the dancers who no longer participated in dance at final follow-up, 7 (65%) quit dancing for nonhip-related reasons. Mean surgery satisfaction (0-10) at final follow-up was 7.1. Four patients (10%) underwent revision hip arthroscopy with revision labral repair. Conclusion: Hip arthroscopy with labral repair in dancers results in sustained improvements in function and pain at minimum 2-year follow-up. Most dancers return to their prior levels of dance, and nearly half remain active several years later. Notably, discontinuation of dance was often unrelated to hip symptoms, underscoring the importance of counseling patients on clinical and lifestyle factors influencing return to sport.

Purpose To prospectively investigate subjective anterior groin pain, patient‐reported outcome measures, complications, reoperation rates, and hip flexion strength after arthroscopic iliopsoas fractional lengthening. Methods From 2023 to 2025, patients with persistent groin pain after total hip arthroplasty refractory to conservative management undergoing arthroscopic iliopsoas fractional lengthening were prospectively identified at 2 tertiary referral centers. Pre‐ and postoperative outcomes at a minimum 6‐month follow‐up including the Visual Analog Scale, Tegner activity scale, Single Assessment Numeric Evaluation, and subjective anterior groin pain and hip flexion strength were analyzed. Results Fifty‐nine hips in 56 patients were included (age: 64.9 ± 9.8 years, 59% women, body mass index: 30.0 ± 5.8 kg/m 2 ) and followed for 10.0 ± 6.9 months postoperatively (range: 4‐25 months). Patients experienced significant ( P < .001) postoperative improvements in the Visual Analog Scale at rest (1.4 ± 2.2 vs 2.8 ± 2.1), Visual Analog Scale with use (3.0 ± 2.9 vs 7.8 ± 1.8), Tegner activity scale (2.8 ± 1.2 vs 2.0 ± 1.0), and Single Assessment Numeric Evaluation score (73.8 ± 22.5 vs 47.7 ± 22.2). Postoperative surgical satisfaction was 8.0 ± 2.7 (scale: 0‐10). Nearly 90% of patients reported feeling much or slightly better regarding their anterior groin pain postoperatively at 2‐week (91%), 6‐week (88%), 3‐month (91%), and final follow‐up (92%). Regarding hip flexion strength, ≥66% reported feeling much or slightly better at 2‐week (73%), 6‐week (95%), 3‐month (89%), and final follow‐up (66%). Three hips (6%) underwent reoperation at the final follow‐up (1 acetabular screw removal with open revision release, 1 revision total hip arthroplasty for loosening, and 1 two‐stage exchange for nonacute periprosthetic joint infection). Conclusions Nearly 90% of patients who underwent arthroscopic iliopsoas fractional lengthening after primary total hip arthroplasty reported improved anterior groin pain, whereas two‐thirds reported increased subjective hip flexion strength throughout the follow‐up. Of note, clinically meaningful improvement in pain at rest was achieved by 50% of patients based on cohort‐specific minimal clinically important difference criteria. Level of Evidence Level IV, retrospective therapeutic case series.

ABSTRACT Many real‐world patients with advanced biliary tract cancer (BTC) are excluded by TOPAZ‐1 criteria; this study assessed cisplatin and gemcitabine plus durvalumab (CGD) efficacy and safety in these patients. Data from 1358 patients with advanced BTC treated with first‐line CGD across 55 international centers were retrospectively analyzed. Patients were classified as TOPAZ‐1‐in (meeting all inclusion criteria) or TOPAZ‐1‐out (meeting ≥ 1 exclusion criterion). Primary endpoints were overall survival (OS) and progression‐free survival (PFS); secondary endpoints included objective response rate (ORR), disease control rate (DCR), and safety. Furthermore, OS and PFS of the TOPAZ‐1‐out cohort were compared with reconstructed survival data from the phase III trial. 912 (67.1%) patients were classified as TOPAZ‐1‐in , and 446 (32.9%) as TOPAZ‐1‐out . After a median follow‐up of 14.5 months (95% CI: 13.7–36.5), OS was 16.1 months in TOPAZ‐1‐in and 12.5 months in TOPAZ‐1‐out (HR 0.69, 95% CI: 14.6–16.5, p = 0.0001); PFS was 8.2 versus 6.5 months (HR 0.73, 95% CI: 7.1–8.1, p < 0.0001). Median OS in the TOPAZ‐1‐out cohort (12.5 months) was nearly identical to the phase III trial experimental arm (12.9 months; HR 1.15, p = 0.13); for PFS the HR was 1.12 (95% CI 0.93–1.42; p = 0.09). Among TOPAZ‐1‐out patients, active infection, elevated bilirubin, and ECOG PS > 1 were linked to poorer OS, while no detrimental impact emerged for ALT/AST abnormalities, corticosteroid use, renal or hematologic parameters, or prior surgery within 6 months, suggesting treatment effectiveness was broadly maintained across clinical subgroups. Furthermore, TOPAZ‐1‐out patients experienced no significant increase in adverse events compared with the TOPAZ‐1‐in group. Real‐world data suggest CGD may be effective in TOPAZ‐1‐out patients, with no evident increase in toxicity, supporting the potential expanded use of the regimen in clinical practice.

Objective: To determine whether sleep apnea–specific hypoxic burden (SASHB) is associated with self-reported hypertension beyond conventional obstructive sleep apnea metrics in rail workers. Methods: Cross-sectional study of 84 Argentine rail workers undergoing home sleep apnea testing. Associations between SASHB and hypertension were evaluated using adjusted logistic regression. Drowsy driving was examined as an unadjusted exploratory secondary outcome. Results: Higher SASHB was independently associated with hypertension in the fully adjusted model (OR per SD 2.42; 95% CI 1.24–5.29; p=0.015). Higher SASHB was also associated with more severe self-reported drowsy driving in unadjusted exploratory ordinal analyses (OR per SD 1.78; 95% CI 1.09–3.28; p=0.035). Conclusions: SASHB may provide complementary information beyond conventional OSA metrics for cardiovascular risk assessment in occupational populations.

ABSTRACT Anti‐Spike monoclonal antibodies (mAbs) progressively lost efficacy during the COVID‐19 pandemic due to the emergence and predominance of resistant SARS‐CoV‐2 variants. By contrast, high‐titre COVID‐19 convalescent plasma (CCP) collected from vaccinated donors recently recovered from infection provides a polyclonal source of antibodies that remains effective in clearing SARS‐CoV‐2 in immunosuppressed patients, unable to mount an adequate immune response against the virus. We conducted a systematic review and individual participant data meta‐analysis to examine the effect of CCP in immunocompromised patients persistently positive for SARS‐CoV‐2 viraemia following mAb therapy, and to evaluate possible biological factors associated with a favourable outcome. Electronic databases were searched for studies published from January 2020 to January 2026. All studies including eligible cases were considered in the systematic review. Unpublished cases were also collected from investigators of the selected studies. The protocol was registered at PROSPERO (CRD420251142891). Forty‐seven cases (30 cases from 12 published studies and 17 unpublished cases) were included. In 33 out of 47 patients (70.2%) with a mAb‐resistant infection, SARS‐CoV‐2 clearance occurred following CCP transfusion, with a mean of 2.7 CCP units administered. In logistic regression, total CCP volume transfused was positively associated with SARS‐CoV‐2 clearance. In conclusion, CCP transfusion was associated with SARS‐CoV‐2 clearance in persistently positive immunocompromised patients following failure of anti‐Spike mAb therapy.

The total number of total hip arthroplasties performed each year is expected to increase significantly over the coming decades. As a result, an increasing number of young patients are undergoing total hip arthroplasty while similarly, a growing subset of active elderly patients desire to return to sports or high-impact activity after surgery. Patients are typically provided restrictions and activities to avoid following surgery. For these patients, there is no clear consensus or guidelines regarding whether they should limit their activity level postoperatively and in particular, if returning to high-impact exercise increases their risk of complications and subsequent revision surgery. This article will discuss the most common complications after total hip arthroplasty and whether patients who return to sports or a high-impact activity after surgery may be more predisposed to these complications in comparison to their more sedentary peers.

Importance Elevated low-density lipoprotein cholesterol (LDL-C) is a modifiable risk factor for cardiovascular disease, the leading cause of premature death worldwide. Assessing the LDL-C–related burden is critical for guiding prevention and treatment strategies. Objectives To estimate the global, regional, and national burden of ischemic heart disease and ischemic stroke attributable to elevated LDL-C (relative to 35-54 mg/dL) from 1990 to 2023 and to quantify the contributions of population growth, aging, risk-deleted burden, and exposure changes to burden trends. Design, Setting, and Population This comparative risk assessment, part of the Global Burden of Disease Study 2023, estimated population-level LDL-C exposure and associated health loss in 204 countries and territories. Mean LDL-C levels were estimated using spatiotemporal gaussian process regression based on 806 studies across 161 countries. Relative risks were derived from meta-analyses of 38 randomized clinical trials. Population-attributable fractions for deaths and disability-adjusted life-years (DALYs) were estimated by age and sex for adults aged 25 years or older from 1990 to 2023, with 95% uncertainty intervals. Exposure Population-level LDL-C concentrations. Main Outcomes and Measures Population-attributable fractions, counts, and rates (all ages and age standardized per 100 000) of LDL-C–attributable deaths and DALYs from ischemic heart disease and ischemic stroke, with uncertainty intervals. Results In 2023, elevated LDL-C accounted for 3.6 million deaths (95% uncertainty interval, 2.2-5.4 million; 6.0% of global mortality) and 90.7 million DALYs (95% uncertainty interval, 58.9-123.3 million; 3.2% of DALYs). Although global all-ages rates remained stable, age-standardized death and DALY rates decreased by 45.6% and 39.5%, respectively, since 1990. In 2023, age-standardized LDL-C–attributable DALY rates were highest in Eastern Europe and lowest in high-income Asia-Pacific. One-third of the global LDL-C burden occurred in India and China. Population growth and aging drove the increasing burden, with notable regional disparities in LDL-C exposure and risk-deleted DALY rates shifting toward middle-sociodemographic settings. Conclusions and Relevance Despite declining age-standardized rates, the absolute LDL-C burden has increased since 1990 due to demographic changes and has shifted toward middle-sociodemographic countries. Measurement and surveillance gaps persist. Strengthened prevention, diagnosis, and treatment access strategies are essential to mitigate the health burden of LDL-C.

ABSTRACT Surgery after response to first‐line chemoimmunotherapy may offer a potential curative option for patients with locally advanced biliary tract cancer (BTC) initially considered unresectable. However, robust real‐world evidence in this setting remains limited. We retrospectively analyzed patients with locally advanced BTC treated with first‐line cisplatin, gemcitabine, and durvalumab (CGD) across 55 centers in 12 countries. Endpoints included overall survival (OS), progression‐free survival (PFS), disease‐free survival (DFS) among resected patients, objective response rate (ORR), and the prognostic impact of surgery. A multivariable logistic regression model was developed to predict surgical conversion using baseline clinical and laboratory variables. Among 1358 screened patients, 219 had locally advanced disease and were included in the analysis. Median follow‐up was 14.5 months. ORR was 34.6%, with median PFS and OS of 10.0 and 20.7 months, respectively. Twenty‐four patients (10.9%) underwent surgical resection after systemic therapy. Median OS was 22.5 months in resected patients versus 19.9 months in those who did not undergo surgery. Median DFS after resection was 15.8 months. Pathological lymph node involvement was independently associated with shorter DFS. Larger baseline tumor size correlated with higher odds of radiological response but not with OS. An exploratory elastic‐net model retained four baseline variables and showed moderate discriminative ability for surgical conversion, with an apparent AUC of 0.72 and an optimism‐corrected AUC of 0.65. First‐line CGD enabled secondary resection in approximately 11% of patients with locally advanced BTC. A simple baseline model may support patient selection for conversion surgery, although prospective validation is needed.
