Purpose To assess the reliability, predictability, and discriminative capacity of 3 anatomic measurements, tibial tubercle‐trochlear groove (TT‐TG), tibial tubercle‐posterior cruciate ligament, and patellar tendon‐lateral trochlear ridge (PT‐LTR), where PT‐LTR may offer a complementary approach to assessing recurrent patellofemoral instability (PFI) risk. Methods Patients diagnosed with PFI before primary patellofemoral stabilization surgery at a single institution between 2022 and 2024 were included. A control group without PFI was propensity matched 1:1 for age, sex, and laterality. Magnetic resonance images were evaluated to measure TT‐TG, tibial tubercle‐posterior cruciate ligament, and PT‐LTR. A priori power analysis determined the cohort size. Statistical analyses compared differences between the PFI and control groups with Student t‐tests, receiver operating characteristic analyses, and area under the curve with resultant sensitivity, specificity, and an optimal cutoff. Results Patients included 50 knees with PFI (28 women, 22 men; mean age 18 ± 5 years). The control group included 50 knees (27 women, 23 men; mean age 18 ± 4 years). Excellent inter‐ and intra‐rater reliability (intraclass correlation coefficient > 0.7) was shown for TT‐TG and PT‐LTR in the PFI and control groups. The distances for TT‐TG, tibial tubercle‐posterior cruciate ligament, and PT‐LTR were significant predictors ( P ≤ .025) of PFI. The average PT‐LTR distance difference for the PFI and control groups was 7.0 mm ( P < .001). PT‐LTR showed an area under the curve of 0.80 and, when ≥4.6 mm, was 66% sensitive and 92% specific for PFI. Conclusions The PT‐LTR distance is a reliable and discriminative metric for identifying PFI in both pediatric and adult populations. A PT‐LTR cutoff value of 4.6 mm showed diagnostic discrimination and substantially high specificity for recurrent PFI, indicating strong ability to identify patients with instability. Level of Evidence Level III, retrospective case control study.

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.

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.

Importance Risk-reducing salpingo-oophorectomy (RRSO) is an effective option to prevent ovarian cancer in high-risk individuals, but adverse effects from premature menopause are a barrier to uptake. Interval salpingectomy with delayed oophorectomy (ISDO) may be an effective alternative. Objective To evaluate the association of ISDO vs RRSO and sexual function and menopausal symptoms. Design, Setting, and Participants This prospective, multicenter, nonrandomized (patient preference) clinical trial was performed among Women Choosing Surgical Prevention participants with a pathogenic or likely pathogenic germline variant conferring an increased risk for ovarian cancer. Patients from 9 US centers were enrolled from June 2, 2016, to October 28, 2020; chose ISDO or RRSO; and were followed up for 24 months. The analysis was performed on November 13, 2024. Interventions Participant-selected RRSO or ISDO. Main Outcomes and Measures Changes in sexual function and menopausal symptoms from baseline to 6, 12, and 24 months. Inverse probability weighting was applied to achieve covariate balance across groups. Results The analytic sample included 334 female participants (mean [95% CI] age at consent, 39.2 [38.7-.9.7] years) who underwent RRSO (n = 165) or ISDO (n = 169) and completed 6-month questionnaires. Significantly more participants experienced clinically meaningful worsening of sexual function at 6 months compared with baseline after RRSO vs ISDO (33.1% [39 of 118] vs 16.8% [17 of 101], respectively; odds ratio, 2.00 [95% CI, 1.20-3.35]) and at 12 months (39.2% [38 of 97] vs 18.3% [17 of 93], respectively; odds ratio, 1.69 [95% CI, 1.09-2.63]). This finding was no longer significant at 24 months. When restricted to the RRSO group who took hormone replacement therapy, there was no significant worsening of total sexual function scores or menopausal symptoms compared with baseline. No interval ovarian cancers were reported. Conclusions and Relevance This nonrandomized clinical trial comparing RRSO with ISDO found that ISDO was less likely to impair sexual function, which addresses an important barrier to surgical prevention in high-risk patients in premenopause. After RRSO, use of hormone replacement therapy mitigated menopausal symptoms and prevented decline in sexual function. More information is needed about the safety of ISDO.

ABSTRACT Clinical pharmacists are increasingly recognized as vital contributors to acute stroke care, yet their role remains inconsistently defined and underutilized across health care systems. This consensus statement explores the expanding presence of clinical pharmacists within interdisciplinary stroke teams, particularly in the management of both acute ischemic stroke ( AIS ) and hemorrhagic stroke. This consensus statement panel was composed of clinical pharmacists, emergency medicine physicians, and a vascular neurologist. The Grading of Recommendations, Assessment, Development, and Evaluation ( GRADE ) approach was used to assess the level of certainty and strength of recommendations. We focused on two questions regarding the clinical pharmacist's role in caring for adult patients presenting to the emergency department ( ED ) with AIS or hemorrhagic stroke. Despite the very low level of evidence, a consensus was reached for the following recommendations: (1) clinical pharmacist involvement in AIS care for adult patients presenting to the ED and (2) clinical pharmacist involvement in hemorrhagic stroke care for adult patients presenting to the ED . Based on the available literature, we believe optimizing the clinical pharmacist role is a critical factor in improving time‐sensitive treatment and equity in care delivery.

PURPOSE In large B-cell lymphoma (LBCL), use of high-dose methotrexate (HD-MTX) to prevent CNS relapse (so-called CNS prophylaxis) remains controversial. International guidelines continue to recommend HD-MTX in patients deemed ultra high risk (UHR) because of a lack of robust data specific to these subgroups. This study was designed to examine the impact of HD-MTX specifically in UHR patients. METHODS Data from two previous retrospective analyses were combined to produce a cohort of UHR patients (≥1 of the following criteria: CNS international prognostic index score 5-6; testicular, renal/adrenal, or breast involvement; ≥3 extranodal sites), treated with or without HD-MTX. The primary outcome was CNS relapse rate (isolated or concurrent with systemic relapse) measured from diagnosis with additional landmark analysis of all responding patients with no progression event at 6 months. RESULTS Analyses were performed on 1,923 patients meeting UHR criteria. No significant difference in 3-year CNS relapse rate was observed between no HD-MTX (n = 1,051) versus HD-MTX patients (n = 872), including in multivariable analyses adjusting for baseline characteristics (3-year rate, 9.3% v 8.1%; adjusted hazard ratio [HR], 1.13 [95% CI, 0.82 to 1.57]). Analyses restricted to isolated CNS relapse also confirmed no difference (5.9% v 5.7%; adjusted HR, 1.03 [95% CI, 0.69 to 1.53]). In the landmark analysis (no HD-MTX n = 782, HD-MTX n = 773), no difference in 3-year CNS relapse was observed (6.7% v 6.6%, adjusted HR, 0.95 [95% CI, 0.62 to 1.44]). CONCLUSION To our knowledge, this is the largest international comparative data set of patients with LBCL with UHR features showing no significant reduction in CNS relapse with HD-MTX in all UHR or in any individual subgroup. Despite inherent limitations of retrospective analyses, the data strongly support previous studies in suggesting HD-MTX prophylaxis has no meaningful benefit for most patients.

INTRODUCTION: Alcohol-associated hepatitis (AH) is a severe condition with high short-term mortality. Identifying key predictors of poor outcomes is critical for guiding therapeutic strategies. Mean arterial pressure (MAP), a key determinant of tissue perfusion and systemic hemodynamics, may play a pivotal role in prognosis. METHODS: We analyzed a multicenter, prospective cohort of 323 patients hospitalized with AH, with validation in an independent cohort of 290 patients. Survival was evaluated using Kaplan-Meier curves and compared with the log-rank (Mantel-Cox) test. Cox proportional hazards models were used to estimate hazard ratios for mortality, adjusted for Model for end stage liver disease score. Mechanistic insights were explored through assessment of cardiovascular biomarkers. RESULTS: A baseline MAP <80 mm Hg was associated with significantly higher mortality at both 28 days (27.3% vs 8.0%) and 90 days (40.3% vs 15.6%; P < 0.001 for both). This association persisted after adjusting for Model for end stage liver disease score, age, and baseline hepatic encephalopathy. The incidence of infections during follow-up was similar across MAP groups (27.6% vs 22.8%), but acute kidney injury occurred more frequently in the MAP <80 mm Hg group (62% vs 38%, P < 0.001). In the validation cohort, patients with MAP <80 mm Hg also demonstrated significantly lower 28-day transplant-free survival. Although B-type natriuretic peptide and plasma renin levels were altered in patients with AH, they did not correlate with MAP values. DISCUSSION: A baseline MAP <80 mm Hg is an independent predictor of short-term and mid-term mortality in patients with AH. Strategies aimed at restoring hemodynamic stability may improve outcomes in this high-risk population.

ABSTRACT As emergency department (ED) crowding and patient boarding reach critical levels nationwide, the role of the emergency medicine pharmacist (EMP) must be both defined and safeguarded. While EMPs are increasingly valued for their contributions to acute care, their responsibilities often unintentionally expand during periods of operational strain, particularly when admitted patients remain in the ED for prolonged durations. EMPs should ideally be resourced to remain focused on time‐sensitive, high‐risk medication management where their expertise is most impactful and not be used as default providers for all pharmacotherapy needs during ED boarding. This perspective outlines our position on the ideal scope of EMP practice during times of congestion, advocating for clearly defined role boundaries, strategic collaboration with other pharmacy team members, and system‐level support to prevent dilution of emergency care. EMPs must be empowered to prioritize critical ED workflows, support resuscitations, and lead initiatives in education, protocol development, and patient safety, without being overextended by responsibilities that can be absorbed by other team members.

Compared with two-dimensional MR elastography (MRE), three-dimensional MRE demonstrated better test-retest repeatability, between–field-strength reproducibility, and between-day reproducibility at 3 T for measurement of liver stiffness in adults with severe obesity but failed more frequently.
