ABSTRACT Objectives To investigate pharmacological treatment patterns in individuals with bipolar disorder (BD) with and without comorbid substance use disorder (SUD) and anxiety disorder (AX), we leveraged the Global Bipolar Cohort to analyze cross‐regional practices across North America, Europe, and the Pacific. Methods Fourteen cohorts contributed aggregate data on pharmacotherapy, demographics, diagnostic subtypes, and comorbidities. Proportional meta‐analyses using generalized linear mixed models were conducted to examine prescription trends and identify clinical differences. Results The sample ( N = 11,521) was 60% female and 84% Caucasian. Participants were categorized into four mutually exclusive groups based on comorbidity status: those with comorbid AX only, comorbid SUD only, both AX and SUD, or neither. The AX+SUD subgroup showed higher rates of attention‐deficit/hyperactivity disorder (ADHD), post‐traumatic stress disorder (PTSD), rapid cycling, obesity, and unemployment, reflecting a more severe clinical profile. Regional variations were notable: North American cohorts reported higher prevalence of AX and SUD than European and Pacific cohorts. Antidepressants use for AX were more common in Europe and the Pacific, while North American prescribing patterns were more variable. Benzodiazepine use was high among individuals with SUD across all regions. Lithium and first‐generation antipsychotic prescriptions varied, with higher rates observed in Europe. Conclusions Findings underscore the heterogeneity of BD and the influence of comorbid AX and SUD on illness burden and treatment. Regional prescribing variations underscore the need for context‐specific guidelines. Gaps in data on medication‐assisted treatment for SUD point to areas for future research. These insights can support more individualized and effective care for complex BD presentations.

Introduction The introduction of the purpose‐built single‐port (SP) robotic platform has allowed for the advent of regionalized minimally invasive surgical approaches for robotic radical prostatectomy (RARP), including the extraperitoneal and transvesical techniques. This study sought to develop a best practice consensus on the key principles, patient selection, surgical techniques, expected clinical outcomes, and learning curves pertaining to SP‐RARP. Methods A modified Delphi consensus was developed by a panel of experts, consisting of a 33‐item questionnaire, with each statement rated using a binary Likert scale (‘agree’ or ‘disagree’). The survey was distributed via email to all practicing SP‐RARP surgeons across the USA and Europe. Consensus was defined as ≥75% agreement on a given statement. Results A total of 53 surgeons participated in the Delphi Consensus across the two rounds. Of 33 statements, 28 (84.8%) reached agreement in the first round. The remaining consensus was achieved in the second round, involving 35 surgeons, and with one additional statement. The panel agreed that, although are no absolute contraindications to SP‐RARP, the preference towards specific SP‐RARP techniques should remain guided by the individual patients and surgical expertise. Although the SP extraperitoneal technique is recommended to pursue pelvic lymph node dissections, the panel agreed that transvesical SP‐RARP showed promise in promoting shorter hospital stay, faster recovery of urinary continence, and utility in patients with extensive prior abdominal surgery. Consensus was also reached on the need for a structured training pathway, with most recommending beginning with extraperitoneal SP‐RARP before advancing to the transvesical approach. Conclusion This Delphi consensus demonstrates broad agreement among experienced SP surgeons in the USA and Europe, forming the foundation for future research on the clinical utility and necessary training pathways for SP‐RARP. Nevertheless, empirical validation based on clinical data from large cohort studies remains important.

Abstract Background The Global Bipolar Cohort (GBC) was established to identify existing bipolar disorder (BD) cohorts worldwide and foster collaborations focused on descriptive and analytic outcomes relevant to BD. A distributed analytic framework has been implemented to engage multiple sites without the need for central data pooling. This report describes the GBC endeavor and global functional impairment patterns. Cross-cohort comparisons of functional correlates are limited by heterogeneous measures and data-sharing constraints. Large, culturally diverse comparisons are needed to distinguish broadly reproducible correlates from cohort-specific effects. Participating sites completed a 28-item descriptive survey covering diagnostic methods, cognition, genetics, treatment, functioning, and follow-up strategies. We implemented a harmonized local logistic regression model of dichotomized functional outcome and shared summary statistics only. Results We identified 69 cohorts across five continents. Thirty-seven cohorts contributed functional outcome analyses from 17,130 participants. Outcome measures included clinician-rated disability scales and social indicators such as employment and marital status. The proportion classified with poor functioning ranged from 16% to 77% (mean 50%). In 32 of 37 cohorts, the overall regression model significantly explained variance in functioning. Current depressive symptoms were the most robust and reproducible correlate of poor functional outcome: they were assessed in 29 cohorts, significant in 22 (75.8%), ranked among the top three correlates in 22, and were the top-ranked correlates in 19. Associations between depressive burden and poor functioning were observed across clinician-rated disability scales and work or social indicators, and across geographically diverse cohorts. Comorbid substance use disorder and medication-related variables were associated with poorer functioning in subsets of cohorts, whereas sex, ancestry, bipolar subtype, psychosis history, and premorbid IQ showed weak or inconsistent associations. Cognitive measures, available in a minority of regression models, showed modest and non-uniform effects. Conclusions Across heterogeneous international cohorts, current depressive symptom burden emerged as the most consistent correlate of poor functioning in bipolar disorder. These findings replicate earlier multisite work at a larger scale, show that protocol-based distributed analyses can identify reproducible clinical signals without sharing individual-level data, and support prioritizing detection and treatment of depressive symptoms when aiming to improve real-world functioning. Future work should expand longitudinal harmonization and representation of under-studied populations.

BACKGROUND: The optimal antithrombotic treatment after transcatheter left atrial appendage closure (LAAC) remains to be determined. The objective of this trial was to compare anticoagulation and antiplatelet therapy for preventing device-related thrombosis (DRT) after LAAC. METHODS: This was a prospective multicenter international randomized trial comparing 2 different antithrombotic strategies for preventing DRT after LAAC in patients with nonvalvular atrial fibrillation. Patients were randomized (1:1) to receive direct oral anticoagulants (DOACs) or dual antiplatelet therapy (DAPT; aspirin+clopidogrel) for 60 days. Patients underwent transesophageal echocardiography at 60 days, and the images were analyzed in a central echocardiography laboratory by experienced echocardiographers blinded to the allocated treatment. The primary outcome was DRT as determined by transesophageal echocardiography 60 days after LAAC in patients receiving the allocated treatment at the time of transesophageal echocardiography (per-protocol analysis). The safety outcome included all-cause mortality, stroke, bleeding, or site-reported DRT within 60 days after LAAC in all randomized patients (intention-to-treat analysis). RESULTS: A total of 510 patients (mean age 77±9 years, 35% women) were included between October 2018 and May 2025, and 253 and 257 patients were randomized to the DOAC and DAPT groups, respectively. Of these, 399 patients underwent transesophageal echocardiography and were receiving the allocated treatment at 60 days after LAAC. The primary outcome occurred in 3 patients (1.5%) in the DOAC group compared with 8 patients (4.1%) in the DAPT group (difference, −2.7% [95% CI, −6.0% to 0.6%]; P =0.110). The safety outcome occurred in 52 patients (22.5%) in the DOAC group compared with 82 patients (34.9%) in the DAPT group (difference, −12.4% [95% CI, −20.6% to −4.2%]; P =0.003), and differences were mainly driven by a lower rate of bleeding events in the DOAC group (44 patients [17.4%] versus 64 patients [24.9%]; difference, −7.5% [95% CI, −14.6% to −0.4%]; P =0.038). CONCLUSIONS: The use of DOACs after LAAC failed to reduce DRT compared with DAPT, but it was associated with an improved safety profile. The results of this study should be interpreted with caution because of statistical power issues related to the narrower-than-expected between-group differences and will need confirmation in future larger studies.

Background: Thyroid fine needle aspiration (FNA) is a widely utilized diagnostic tool for evaluating thyroid nodules. The Bethesda System for Reporting Thyroid Cytopathology (BSRTC) provides a standardized framework for classifying cytologic findings and guiding management. This study retrospectively reviews thyroid FNA cases at a large academic institution to analyze the distribution of Bethesda classifications.Methods: A retrospective review was conducted of all thyroid FNA cases done in the department of Endocrinology at a large academic institution performed from January 1st 2019 to October 3rd 2023. Thyroid FNA results were divided into categories according to the Bethesda classification system, such as benign, atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS), follicular neoplasm (FN), suspicious for malignancy, malignancy and non-diagnostic. FNA results that were not able to be classified were labelled as other.Results: A total of 3,291 thyroid FNA cases were included in the analysis. The distribution of cases across the Bethesda categories revealed a significant proportion of benign findings, with 73.6% classified as benign. This was followed by 8.1% follicular neoplasm, 6.56% Papillary Thyroid Cancer, 6.62% Non-diagnostic, 2.4% Atypical, and 2.3% Suspicious. 0.5% of FNA results were classified as other.Conclusion: Overall our cohort was found to have similar findings in terms of benign and confirmed PTC nodules compared to recent literature; however, the rate of atypical and non-diagnostic nodules was found to be lower.

Background: Data on cognition in patients with primary aldosteronism (PA) are scarce. Mild autonomous cortisol secretion (MACS), defined based on post-dexamethasone cortisol >1.8 mcg/dL, is diagnosed in 20-30% of patients with PA. The impact of MACS on the cognition of patients with PA is unclear. Objectives: 1) to assess cognition in patients with PA versus sex-matched referent subjects with hypertension, 2) determine the differences in cognition of patients with PA (with and without MACS) and patients with MACS. Methods: A cross-sectional study, 2019-2023. Cognition was assessed by National Institute of Health Toolbox Cognition Battery and reported as T-score corrected for age, sex, race, and education. Only subjects with hypertension were included. Results: Cognitive assessment was performed in 52 patients with PA (including 11 patients with both PA and MACS, median age of 51 yrs, 30, 58% women), 47 patients with MACS (median age of 57 yrs, 31, 66% women), and 52 referent subjects (median age of 66 yrs, 30, 58% women). When compared to referents, and after age adjustment, patients with PA had lower cognition: fluid composite cognition β of -6.3 (P=0.014) and total composite of -5.6 (P=0.016). When compared to patients with MACS, and after age and sex adjustment, patients with PA had a similar total composite cognition score (β=3.6, P=0.108) but a higher fluid composite score (β=4.7, P=0.044). No differences in cognition were found between patients with PA with and without MACS, possibly due to low sample size. Conclusion: Patients with PA demonstrate lower cognition when compared to referents with hypertension. Patients with PA had a higher fluid cognition compared to patients with MACS. Future studies should delineate the impact of hyperaldosteronism vs MACS on cognition of patients with PA. Presentation: Monday, July 14, 2025

Background: Bone density and structure-related disorders, such as osteoporosis and related fractures, significantly contribute to morbidity and mortality, particularly among aging populations. Monitoring temporal trends and geographic variations in mortality is essential to inform targeted public health interventions. In this study, we aimed to examine temporal and geographic variations in mortality associated with bone density and structure-related disorders in the United States from 1999 to 2022. Methods: Using ICD-10 codes M80-M85, this retrospective ecological study utilized mortality data extracted from the CDC WONDER database for the years 1999-2022. Age-adjusted mortality rates (AAMRs) were calculated and stratified by demographic variables (age, sex, and race/ethnicity) and geographic regions. Temporal trends were analyzed using Joinpoint regression to estimate annual percent changes (APCs). Geographic variations were visualized using choropleth maps, and subgroup analyses were performed to explore disparities. Statistical significance was set at p < 0.05. Results: Age-adjusted mortality rates (AAMRs) for bone density and structure-related disorders decreased overall from 1999 to 2019, with a subsequent rise observed in 2020 and 2022. Joinpoint regression revealed a significant negative trend from 2007-2016 (APC = -7.46%, p < 0.000001), followed by a positive reversal from 2019-2022 (APC = 3.78%, p = 0.013). Both males and females experienced declines in mortality, but females had a slightly higher APC of -3.10% compared to -2.82% for males. Asian/Pacific Islander groups exhibited the most pronounced decrease in mortality (APC = -11.92%, p < 0.000001) from 2009-2015, with a positive rebound in recent years. Black or African American populations had the smallest decline (APC = -1.35%). The Southern U.S. experienced the steepest decline in mortality from 2010-2016 (APC = -10.92%, p < 0.000001), followed by a strong positive trend from 2019-2022 (APC = 6.61%, p < 0.000001). Conversely, the West and Northeast regions showed milder trends with less pronounced reversals. Older age groups (65-74, 75-84) showed significant decreases in mortality, particularly the 65-74 group, which reversed to a positive trend (APC = 6.97%) from 2019-2022. The highest number of deaths occurred at the decedent’s home (3,330 in 2022). Subgroup analyses indicated significant temporal shifts in the mortality patterns across different racial/ethnic groups and geographic regions. Hispanic/Latino and Asian/Pacific Islander populations exhibited an increase in mortality rates post-2019, particularly in 2020. Conclusion: From 1999 to 2022, mortality from bone density and structure-related disorders in the U.S. exhibited significant temporal and geographic variations. These findings highlight the need for targeted public health strategies. Presentation: Monday, July 14, 2025

Abstract Disclosure: J.R. Hewlett: None. J.G. Sfeir: None. R.A. Wermers: None. J.J. Schmitz: None. Percutaneous ethanol ablation (PEA) is a non-surgical technique used in the management of hyperparathyroidism (HPT) since the 1980s. Previously published cohorts are small and/or focused on patients with primary hyperparathyroidism (PHPT) in the setting of multiple endocrine neoplasia type 1 (MEN1). New randomized controlled trial data suggests similar response rates between parathyroidectomy and PEA (98.5% vs 91.1%) for uniglandular disease, and a previously published cohort of PEA in patients with MEN1 and recurrent multiglandular PHPT at our institution reported post-PEA normocalcemia in 74.5% of patients. This retrospective cohort study examined the treatment response to PEA in those with PHPT (including MEN1) and tertiary HPT (THPT) at a single institution between 1997-2023. Those with secondary hyperparathyroidism or eucalcemic PHPT were excluded. The primary outcome was a serum calcium ≤10.1 mg/dL at 3-6 months and secondary outcomes included number and volume of ethanol injections, time to recurrence of HPT, and complications of PEA. A total of 83 patients were included. Most were women (62.7%) and the median age at diagnosis of HPT was 40 years. The majority had PHPT (90.4%), and many (86.7%) had previously undergone surgery. The most common indications for PEA were risk for hypoparathyroidism with additional surgery (72.3%) poor surgical candidacy (16.9%), and patient preference (8.4%). The mean calcium was 10.7 mg/dL (95% CI 10.56-10.85) and the mean PTH was 164 pg/mL (95% CI 120.6-208.3) prior to PEA. The mean number of ethanol injections was 3.0 (95% CI 2.6 – 3.4) and the cumulative volume of ethanol was 1.2 mL (95% CI 1.0-1.4). At 3-6 months, 68.3% of treated patients had calcium ≤10.1 mg/dL with a mean value of 9.4 mg/dL (95% CI 9.1-9.6). Of those, 42% did not have recurrence at most recent follow-up. Of those with recurrence, a post-PEA calcium ≤10.1 mg/dL at 3-6 months was associated with a longer time to recurrence than those without (36.9 months versus 3.75 months; P=0.0009). There was no significant difference between the number of times (P=0.56) or the volume (P=0.41) of ethanol injected between those with calcium of ≤10.1 mg/dL at 3-6 months and those without. Hypocalcemia was observed in 8 (9.6%; transient in 75%), hypoparathyroidism in 3 (3.6%; transient in 66.7%), laryngeal nerve injury in 2 (2.4%; transient in 50%), and hoarseness in 9 (10.8%; transient in 100%) patients. This is the largest North American cohort of patients who received PEA for HPT and represents a broader review of HPT than previously published. Our rate of post-PEA eucalcemia is lower than previously reported, however this cohort was complex with a high proportion of multiglandular disease (80.7%), MEN1 (39.8%) and prior surgeries (mean 1.7 per person; 95% CI 1.5-1.9). PEA remains a safe and effective treatment for patients with recurrent HPT, especially those at high risk of post-surgical hypoparathyroidism. Presentation: Monday, July 14, 2025

Background: Previous studies have demonstrated that C11 choline positron emission tomography/computed tomography (Choline-PET/CT) can localize abnormal parathyroid glands in the re-operative setting. This study assesses a large volume of patients with primary hyperparathyroidism (1HPT) who underwent Choline-PET/CT to confirm its utility in the setting of negative or equivocal conventional imaging. Methods: All patients who underwent Choline-PET/CT for evaluation of 1HPT from July 2017 to July 2024 at a single institution were reviewed. Inclusion criteria were patients who underwent parathyroidectomy and had lab testing to assess for cure (defined as >50% drop from baseline PTH and into normal range, or resolution of hypercalcemia at follow-up). Sensitivity, positive predictive value (PPV), false negative rate (FNR), and accuracy were compared to conventional imaging (neck ultrasound, parathyroid scan, and parathyroid four-dimensional CT (4D-CT)). Subgroup analysis was conducted comparing sensitivity of modalities among index operations, and separately in re-operations. Results: 176 patients were identified. 85 underwent parathyroidectomy, 1 patient was excluded due to lacking data to evaluate for cure. Of 91 patients who did not undergo parathyroidectomy, 45 were non-localizing on all imaging, and 46 had positive Choline-PET/CT findings but opted against surgery due to mild disease or prohibitive re-operative risk. Of the included 84 parathyroidectomy patients, 61 failed to localize on at least one conventional modality, and 15 failed to localize on all conventional studies. 67 patients (80%) achieved cure, of whom 53 were re-operations (range of 1-4 prior operations, average 1.5). Choline-PET/CT outperformed conventional modalities across sensitivity, PPV, FNR, and accuracy. Among index operations, Choline-PET/CT had significantly higher sensitivity than conventional modalities (100% vs 27% for ultrasound, 30% for parathyroid scan, 29% for 4D-CT; p values ≤0.01). This was also true in re-operations (95% for Choline-PET/CT vs 13% for ultrasound, 30% for parathyroid scan, 32% for 4D-CT; p values <0.01). Conclusion: C11 choline-PET/CT is a valuable imaging modality in the re-operative setting and demonstrates utility for index operations. It provides localization when other modalities fail and allows for a high surgical cure rate. Further investigation into its utility as a primary imaging modality is warranted.

Introduction: Tirzepatide, a dual GIP and GLP-1 receptor agonist, is an FDA-approved medication demonstrating the highest efficacy for weight loss among currently available treatments. However, the influence of sex and age on weight loss outcomes with tirzepatide remains unclear. Objective: To investigate the influence of sex and age on weight loss outcomes in patients treated with tirzepatide. Methods: This retrospective study evaluated weight loss outcomes associated with tirzepatide across sex and age groups. Patients with active malignancy, prior bariatric surgery, or concurrent anti-obesity medication were excluded. The primary endpoint was total body weight loss percentage (TBWL%) at 15 months by sex and age. The influence of age was analyzed as a categorical (≤45, 46-59, ≥60 years) and continuous variable. Secondary outcomes included TBWL% at 3, 6, 9, and 12 months by sex and age. Data were analyzed using independent t-tests, one-way ANOVA, and multivariate regression; results are reported as mean ± standard deviation. Results: The study included 1033 patients (57.1% female; mean age 56 ± 11 years; mean BMI, 37.7 ± 8 kg/m2). By age category, 18.8% (196) were ≤45 years (35.7% males, 64.3% females), 45.9% (473) were 46-59 years (42.7% males, 57.3% females), and 35.3% (364) were ≥60 years (54.7% males, 45.3% females). At all timepoints, TBWL was significantly greater in females compared to males at all timepoints. At 15 months females had a higher TBWL than males: 15.3% ± 10, n=340, vs. 10.2% ± 8, n=244, (p < 0.001). Among females, premenopausal women achieved a higher TBWL than postmenopausal women: 16.9% ± 10 vs 14.4% ± 9, p = 0.04. Analysis by age groups revealed a trend toward higher TBWL in younger patients that did not reach statistical significance (p = 0.152): ≤45 years (14.7% ± 10%), 46-59 years (12.9% ± 10%), and ≥60 years (12.7% ± 9%). After adjusting for baseline age, BMI, and diabetes status, sex remained a strong predictor for weight loss outcomes (PE= 4.5, 95% CI [2.96, 5.97], p < 0.001), following type 2 diabetes status (PE= 4.8, 95% CI [3.0, 6.7], p < 0.001). Conclusion: Sex but not age was a strong predictor of weight loss with tirzepatide. Female sex was associated with greater weight loss than male sex. These results emphasize the importance of considering sex-specific factors in weight loss strategies and warrant further investigation into the underlying biological mechanisms. Differential weight loss by menopause, underscores the role of sex hormones. Presentation: Monday, July 14, 2025
