BACKGROUND AND OBJECTIVES: Social determinants of health (SDOH), such as education, insurance, race, and income, significantly affect a patient's medical care and surgical outcomes. Additional studies characterizing the impact of SDOH on patients undergoing spine surgery are needed. Accordingly, this study evaluates the impact of SDOH on severity of symptoms at presentation and discharge disposition in patients undergoing surgical treatment of cervical myelopathy. METHODS: A retrospective single-center study identified adult patients undergoing surgical intervention for cervical myelopathy between 2016 and 2020. Cohort characteristics were collected from patient medical records. The t -test, Wilcoxon rank-sum, analysis of variance, Kruskal-Wallis, and χ 2 tests were used to compare variables when appropriate. Multivariable linear and logistic regression analyses were conducted for modified Japanese Orthopaedic Association (mJOA) and discharge disposition. All statistical analysis was performed in MATLAB R2022b (MathWorks, Natick, MA). RESULTS: A total of 480 patients were included in the study with a male predominance of n = 281 (59%) and a mean age of 62 ± 13 years. Racial demographics included 64% White (n = 308) and 36% Non-White (n = 172) patients. On univariable analysis, mJOA at presentation was significantly associated with employment status ( P < .01), annual income ( P < .01), education level ( P < .01), and insurance status ( P = .03). On multivariable analysis, annual income and education level continued to be significant predictors of presenting mJOA. On univariable analysis, discharge disposition was associated with body mass index ( P = .01), mJOA at presentation ( P < .01), employment status ( P = .05), annual income ( P < .01), education level ( P < .01), insurance ( P < .01), approach ( P < .01), and length of stay ( P < .01). On multivariable analysis, mJOA at presentation, education level, insurance, and approach continued to be significant predictors of discharge disposition. CONCLUSION: SDOH affect the severity of symptoms at presentation and discharge disposition in patients undergoing surgery for cervical myelopathy. Understanding these dynamics and uncovering additional SDOH are critical for enhancing surgical care and achieving equitable healthcare outcomes.

e23011 Background: Eligibility criteria for clinical trials are crucial for maintaining safety and study integrity. However, they often exclude patients due to medical conditions that are not relevant, leading to gaps in understanding the real-world effectiveness of treatments. Addressing potentially modifiable exclusions (PMEs) could enhance accessibility and participation in trials without compromising safety, particularly given the low rates of enrollment. Methods: We retrospectively analyzed ‘screen-failed’ patients (those who were excluded after providing consent because they did not meet the eligibility criteria or other protocol requirements) with biliary tract (BTC) or pancreatic cancer (PDAC) between August 2019 and November 2024. Screening logs and electronic health records provided clinical data. PMEs were identified and validated by two independent medical oncologists. Results: Of 585 screen-failed patients from 18 trials, 76 were excluded due to incomplete data. Among the 509 patients analyzed (367-PDAC, 142-BTC), the leading causes of screen failure were declined participation (99, 19%), comorbidities (59, 12%), suboptimal organ function (56, 11%), absence of biomarker (49, 10%), and insufficient biospecimens (36, 7%). Among patients declining participation, reasons included preference for standard care (23%), travel (22%), competing trials (5%), adverse event concerns (4%), financial issues (3%), and unknown reasons (43%). Of the 509 patients deemed ineligible for study entry at screening, we identified 69 patients (13.6%) with PMEs, primarily related to borderline laboratory abnormalities: liver function (16, 23%), kidney function (14, 20%), platelet count (8, 12%), hemoglobin (5, 7%), and white blood cell count (4, 6%). Other PMEs included previous or concurrent malignancies (6, 9%) and viral hepatitis (3, 4%). PMEs were evenly distributed across trials. Notably, all screen-failed patients proceeded to receive standard therapy. Conclusions: This analysis underscores the potential for rigid eligibility criteria to exclude stable patients who might benefit from investigational treatments. Easing specific criteria, particularly those related to laboratory abnormalities, could broaden trial accessibility. Furthermore, examining the reasons for declined participation and addressing PMEs could help develop strategies to enhance trial enrollment.

Importance Nontraumatic subarachnoid hemorrhage (SAH) represents the third most common stroke type with unique etiologies, risk factors, diagnostics, and treatments. Nevertheless, epidemiological studies often cluster SAH with other stroke types leaving its distinct burden estimates obscure. Objective To estimate the worldwide burden of SAH. Design, Setting, and Participants Based on the repeated cross-sectional Global Burden of Disease (GBD) 2021 study, the global burden of SAH in 1990 to 2021 was estimated. Moreover, the SAH burden was compared with other diseases, and its associations with 14 individual risk factors were investigated with available data in the GBD 2021 study. The GBD study included the burden estimates of nontraumatic SAH among all ages in 204 countries and territories between 1990 and 2021. Exposures SAH and 14 modifiable risk factors. Main Outcomes and Measures Absolute numbers and age-standardized rates with 95% uncertainty intervals (UIs) of SAH incidence, prevalence, mortality, and disability-adjusted life-years (DALYs) as well as risk factor–specific population attributable fractions (PAFs). Results In 2021, the global age-standardized SAH incidence was 8.3 (95% UI, 7.3-9.5), prevalence was 92.2 (95% UI, 84.1-100.6), mortality was 4.2 (95% UI, 3.7-4.8), and DALY rate was 125.2 (95% UI, 110.5-142.6) per 100 000 people. The highest burden estimates were found in Latin America, the Caribbean, Oceania, and high-income Asia Pacific. Although the absolute number of SAH cases increased, especially in regions with a low sociodemographic index, all age-standardized burden rates decreased between 1990 and 2021: the incidence by 28.8% (95% UI, 25.7%-31.6%), prevalence by 16.1% (95% UI, 14.8%-17.7%), mortality by 56.1% (95% UI, 40.7%-64.3%), and DALY rate by 54.6% (95% UI, 42.8%-61.9%). Of 300 diseases, SAH ranked as the 36th most common cause of death and 59th most common cause of DALY in the world. Of all worldwide SAH-related DALYs, 71.6% (95% UI, 63.8%-78.6%) were associated with the 14 modeled risk factors of which high systolic blood pressure (population attributable fraction [PAF] = 51.6%; 95% UI, 38.0%-62.6%) and smoking (PAF = 14.4%; 95% UI, 12.4%-16.5%) had the highest attribution. Conclusions and Relevance Although the global age-standardized burden rates of SAH more than halved over the last 3 decades, SAH remained one of the most common cardiovascular and neurological causes of death and disabilities in the world, with increasing absolute case numbers. These findings suggest evidence for the potential health benefits of proactive public health planning and resource allocation toward the prevention of SAH.

Abstract Objectives The lack of uniform terminology and abbreviations for anti-synthetase syndrome has led to significant challenges in research and clinical practice. This study aimed to establish an international consensus on a standardized nomenclature and abbreviation among a diverse group of global myositis experts and patient representatives. Methods This qualitative project was approved by the International Myositis Assessment and Clinical Studies Group (IMACS). Based on the outcomes of a literature review and preliminary survey, list of terms for nomenclature and abbreviations was finalized. Subsequently, two rounds of the Delphi survey were conducted among myositis experts and patient participants to ascertain current practices and preferences. Using Nominal Group Technique (NGT), the project steering committee developed a consensus nomenclature and abbreviation. Results A total of 241 and 132 myositis experts from six continents, 35 countries and 9 specialities participated in round 1 and round 2 of the Delphi survey, respectively. The results indicated a preference for the terms anti-synthetase syndrome, antisynthetase syndrome and anti-tRNA synthetase syndrome. The abbreviations ASS, ASyS and ASSD were most used, though ASS received notable disapproval. The steering committee, including twenty-five myositis experts and three patient representatives from diverse backgrounds and geographical locations, reached a consensus on ‘anti-synthetase syndrome’ as the preferred nomenclature and ASyS as the preferred abbreviation, with 100% and 93.1% votes, respectively. Conclusion The terms anti-synthetase syndrome and ASyS should be adopted as the standard nomenclature and abbreviation in both research and clinical practice. This standardization is expected to increase consistency within the literature.

ABSTRACTBackgroundComparisons of outcomes after transcatheter aortic valve replacement with balloon‐expandable (BEV) versus self‐expanding (SEV) valves are limited.HypothesisThis study aimed to compare clinical and hemodynamic outcomes of BEV and SEV at short‐term (30 days), midterm (1 year), and long‐term (> 1 year) endpoints.MethodsPubMed, Embase, Scopus, and Cochrane Library databases were searched until July 2024 for randomized controlled trials. Random‐effect model (DerSimonian–Laird method) was used to pool the risk ratios (RR), mean differences, and 95% confidence intervals (CI).ResultsA total of 10 studies comprising 4325 patients (2295 BEV, 2030 SEV) were included. In short‐term, cardiovascular (RR: 0.56, 95% CI: 0.36–0.87) and all‐cause mortality (RR: 0.54, 95% CI: 0.35–0.81) were lower in the BEV group. Risk of moderate to severe paravalvular leak (PVL) was lower among BEV patients in short‐term (RR: 0.28, 95% CI: 0.17–0.49) and long‐term (RR: 0.28, 95% CI: 0.1–0.79). A limited number of studies showed a greater risk of clinical valve thrombosis on BEV in midterm and long‐term. The need for permanent pacemaker implantation was lower in BEV at both short‐term (RR: 0.56, 95% CI: 0.37–0.87), and midterm (RR: 0.78, 95% CI: 0.64–0.94). The SEV group had a larger effective orifice area with lower mean transvalvular pressure gradient at all endpoints.ConclusionsBEV is associated with reduced risk of clinical outcomes in short‐term; however, most differences diminish in longer evaluations, except for moderate to severe PVL, which remains elevated for SEV. SEVs had better hemodynamic results and lower risk of clinical valve thrombosis.

Abstract Introduction Obesity, defined as an elevated Body Mass Index (BMI) &gt;30, is a prevalent public health concern with far-reaching implications for various medical procedures and outcomes. In the context of inflatable penile prosthesis placement (IPP), where patient well-being and surgical success are of paramount importance, the impact of obesity on postoperative and intraoperative complications warrants thorough investigation. Objective We aimed to investigate the impact of BMI on both postoperative and intraoperative complications in an international, multi-institutional cohort of patients who underwent IPP placement. Methods We performed a retrospective chart review of 4,398 cases. These cases were divided into two distinct groups based on BMI: less than 30 (n = 2,260) and greater than or equal to 30 (n = 2,138). The study assessed various surgical factors as well as complications, including overall complications, corporal scarring, incontinence, intraoperative complications, proximal perforation, distal perforation, proximal crossover, distal crossover, and urethral injury. Results Our analysis revealed that there were no statistically significant differences in intraoperative or postoperative complications between the two BMI categories. Notably, proximal corporal measurement was significantly higher for &gt;30 BMI group with 1858 (86.9%) compared to 1919 (84.9%) for &lt;30 BMI group, (p = &lt; 0.001). The incidence rates for overall complications (30.2% vs. 28.7%; p = 0.164), corporal scarring (18.2% vs. 16.7%; p = 0.36), incontinence (3.53% vs. 3.13%; p = 0.076), intraoperative complications (1.94% vs. 1.68%; p = 0.253), and specific complications all exhibited no significant differences. Similarly, post-operative complications, including both non-infectious (6.99% vs. 6.22%; p = 0.215) and infectious (2.61% vs. 1.87%; p = 0.165) complications, did not significantly vary between BMI categories. Conclusions Our findings indicate that BMI does not exert a statistically significant influence on postoperative and intraoperative complications in the context of high-volume prosthetic urology. In the absence of any other differences between patients of differing BMIs, the IPP industry may need to consider device specific alterations with pump tubing length in obese patients.
