Background: Spontaneous Coronary Artery Dissection (SCAD) is a cause of acute coronary syndrome, particularly among women, and is associated with psychological distress, including depression, anxiety, and post-traumatic stress (PTSD) symptoms. Fibromuscular dysplasia (FMD), a vascular condition that alters the arteries, is often found in patients with SCAD, adding complexity and uncertainty with a second serious diagnosis. This study examined the differences in mental health symptoms between SCAD survivors with and without FMD to better understand their unique psychosocial needs and inform interventions to enhance patient outcomes. Methods: Patients diagnosed with SCAD within the past 3 years were recruited from 6 Canadian cardiac hospitals. Participants completed questionnaires assessing socio-demographics, comorbidities, and validated psychological measures, including Patient Health Questionnaire-9 (PHQ-9) for depression, Generalized Anxiety Disorder-7 (GAD-7) for generalized anxiety, Cardiac Anxiety Questionnaire (CAQ) for cardiac-related anxiety, and PTSD Checklist (PCL-5) for PTSD symptoms. Differences in mental health outcomes between SCAD survivors with and without FMD were analyzed using t-tests for continuous variables and chi-square tests for categorical variables. Results: The study included 326 participants (92.9% female; mean age 53.3 years), with 67 participants (20.6%) having a confirmed diagnosis of FMD at the time of questionnaire completion (39.3% FMD at study completion). Post-SCAD, patients with FMD reported significantly higher scores than patients without FMD on the GAD-7 (6.4±5.9 vs. 4.7±4.9, p = .028), CAQ (29.9±13.1 vs. 26.0±12.3, p = .023), and PCL-5 (17.2±15.4 vs. 13.3± 14.0, p = .048). The proportion of SCAD survivors with FMD scoring in the clinically diagnostic range was significantly higher than those in patients without FMD: 32.8% vs. 20.8% for depression, 31.3% vs. 17.4% for anxiety, 64.2% vs. 49.2% for cardiac anxiety, and 25.4% vs. 11.6% for PTSD (all p < .05). Conclusions: Our findings suggest that SCAD survivors with comorbid FMD experience significantly higher distress —depression, generalized anxiety, cardiac-related anxiety, and PTSD symptoms—compared to those without FMD. Longitudinal research is needed to explore the role of these mental health concerns in long-term mental health and cardiac outcomes. Enhanced psychological interventions for those with FMD may be required.

Background: We investigated the impact of genetic risk factors for coronary heart disease (CHD) -polygenic risk score (PRS), familial hypercholesterolemia (FH), and family history (FamHx)- on CHD risk estimates, across the age spectrum, in two diverse cohorts of US adults -eMERGE IV (eIV) and All of Us (AoU). Methods: CHD was defined as myocardial infarction, unstable angina, and coronary revascularization. Self-identified race/ethnicity (SIRE) was used as a population descriptor. We calculated a PRS for CHD (PRS CHD , PGS004698), ascertained FH as the presence of pathogenic/likely pathogenic variants in FH genes, and defined FamHx as early-onset CHD in first-degree relatives. We employed Pooled Cohort Equations (PCE) to estimate the 10y risk of CHD for adults ≥40y and modeled the association of conventional risk factors with CHD in adults <40y. AoU served as the training set, and eIV as the testing set. We analyzed the impact of PRS CHD and FamHx on CHD risk estimates by a) using multivariable logistic regression and Cox proportional hazard models, assessing discrimination and the extent of risk reclassification; and b) net benefit analysis and decision curves to assess the performance of prediction models across actionable thresholds. Results: We analyzed data for 19348 participants from eIV (age 50±15, 68% female, 41% non-White) and 239645 participants from AoU (age 55±17, 61% female, 48% non-White). Genetic risk factors were significantly associated with CHD. PRS CHD performance varied by SIRE groups, while FamHx was consistent. The effects of PRS CHD and FamHx on CHD were independent and additive (Figure 1). In adults ≥40y, incorporating PRS CHD and FamHx into PCE improved discrimination (C-statistic increased from 0.719 to 0.753; P -diff=9.1×10 -3 , Figure 2) and reclassified risk in 19% and 20% of participants at the 7.5% and 10% 10y CHD risk thresholds, respectively. Between the 7.5% and 10% 10y CHD risk thresholds, incorporating PRS CHD and FamHx into the PCE improved the net benefit of the risk prediction models across White, Black, and Hispanic/Latino groups (Figure 3). Conclusion: PRS CHD and FamHx were independently and additively associated with CHD in two large diverse cohorts in the US. Incorporating PRS CHD and FamHx into PCE improved risk discrimination, reclassified risk in a significant portion of participants, and improved net benefit of the PCE across all three major SIRE groups, motivating the addition of these factors to clinical risk calculators.

Treatment-induced ovarian function loss is a significant concern for many young patients with breast cancer. Accurately predicting this risk is crucial for counselling young patients and informing their fertility-related decision-making. However, current risk prediction models for treatment-related ovarian function loss have limitations. To provide a broader representation of patient cohorts and improve feature selection, we combined retrospective data from six datasets within the FoRECAsT (Infertility after Cancer Predictor) databank, including 2679 pre-menopausal women diagnosed with breast cancer. This combined dataset presented notable missingness, prompting us to employ cross imputation using the k-nearest neighbours (KNN) machine learning (ML) algorithm. Employing Lasso regression, we developed an ML model to forecast the risk of treatment-related amenorrhea as a surrogate marker of ovarian function loss at 12 months after starting chemotherapy. Our model identified 20 variables significantly associated with risk of developing amenorrhea. Internal validation resulted in an area under the receiver operating characteristic curve (AUC) of 0.820 (95% CI: 0.817–0.823), while external validation with another dataset demonstrated an AUC of 0.743 (95% CI: 0.666–0.818). A cutoff of 0.20 was chosen to achieve higher sensitivity in validation, as false negatives—patients incorrectly classified as likely to regain menses—could miss timely opportunities for fertility preservation if desired. At this threshold, internal validation yielded sensitivity and precision rates of 91.3% and 61.7%, respectively, while external validation showed 92.9% and 60.0%. Leveraging ML methodologies, we not only devised a model for personalised risk prediction of amenorrhea, demonstrating substantial enhancements over existing models but also showcased a robust framework for maximally harnessing available data sources.

ABSTRACT Suicidality contributes substantially to global morbidity and mortality, yet despite its heritability, its biological etiology remains largely elusive. We conducted multi-ancestry genome-wide association study meta-analyses of suicidal ideation (259,747 cases), suicide attempt (64,993 cases), suicide death (9,197 cases), and suicidal behavior (suicide attempt/ death, 75,300 cases), across 54 cohorts (e.g., the Psychiatric Genomics Consortium, Million Veteran Program, UK Biobank). We identified 77 significant loci across meta-analyses, including 59 previously unreported for suicidality. SNP-based heritability ranged from 2.0-6.7% and there were strong, yet incomplete, genetic correlations between suicidality phenotypes (0.70-0.88). Fine-mapping prioritized putative causal SNPs and 20 credible genes. Enrichment analyses implicated synaptic pathways and neuronal populations predominantly in subcortical brain regions (e.g., amygdala excitatory, medium spiny, hippocampal CA1-3). Together, these findings establish suicidality as a polygenic set of traits with both shared and distinct genetic influences, providing a foundation for future studies of suicide biology and etiology.

Background: Patients performing self-triage for chest pain need to pick an algorithm which includes questions pertinent to chest pain to triage accurately. Objective: Our study reviews patient self-triage choices and outcomes for patients who completed an online self-triage encounter before being triaged by a nurse for chest pain. Methods: Patients who underwent telephone nurse triage for chest pain, and also had an online self-triage encounter within the prior 24 hours were reviewed for the frequency with which they chose “chest pain” as their symptom to triage for during self-triage, whether they reported chest pain during the self-triage encounter (if asked as part of the algorithm for their chosen self-triage symptom) and whether the patient had any follow up evaluation within 1 week. Results: There were 70 self-triage and nurse triage dyads during the study period where triage nurses chose “chest pain” as the primary symptom to be triaged for during the telephone triage encounter. Of these, only 5 (7.1%) patients chose the “chest pain” self-triage option during online self-triage. During the self-triage encounter, 50 (71%) reported chest pain, 10 (14%) denied chest pain and 10 chose to self-triage their symptoms with an algorithm that did not include a question on whether chest pain was present. Of the 70 total dyads 59 (84%) had a follow up emergency department (40 patients) or office visit (19 patients) documented. Conclusion: Most patients chosen to be triaged for chest pain by triage nurses did not choose the online self-triage algorithm for chest pain even though the majority did report chest pain during their self-triage encounter (when asked). This is concerning from a safety perspective as a non-chest pain self-triage option chosen by the patient may not always ask about the presence or absence of chest pain and thus could increase the risk of being triaged inaccurately. Implications for improvement of self-triage could include diagrams for patients to choose the symptom area.

Background: Data on cognition in patients with primary aldosteronism (PA) are scarce. Mild autonomous cortisol secretion (MACS), defined based on post-dexamethasone cortisol &gt;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

Objective: To determine the duration of postoperative AI and to identify factors associated with the duration of AI in patients undergoing surgery for endogenous hypercortisolism.Methods: We conducted a single center prospective cohort study, 2019-2024, of patients with endogenous hypercortisolism [Cushing syndrome (CS) or mild autonomous cortisol secretion (MACS)] treated with surgery. Associations of demographics, BMI, clinical and biochemical hypercortisolism severity, subtype of hypercortisolism, presurgical hypercortisolism duration and glucocorticoid type in relation to duration of AI were investigated. Results: The 110 patients [36% MACS, 46% pituitary CS, 15% adrenal CS, 3% ectopic CS, median age 50 years (IQR: 40-60), 82% women] who developed postsurgical AI were followed for a median duration of 26 months (IQR: 15-38). By the end of follow up, 96 patients (87%) had recovery of AI. The median time to recovery of AI was shorter in MACS vs. Overt Cushing syndrome (3.0 months (95% CI: 2.5-6.2) vs. 12.3 months (95% CI 9.0-17.3), P =0.002). Biochemical severity score (r=0.32, P=0.002) and duration of preoperative hypercortisolism symptoms (r=0.29, P=0.005), but not age, sex, BMI, clinical severity, or glucocorticoid type were associated with the duration of AI. We found no differences in the duration of AI between patients with ACTH-dependent vs ACTH-independent CS (12.3 months (95% CI: 6.0-17.2) vs 13.9 months (95% CI: 9.0-25.5), P =0.7).Conclusion: In this interim analysis, we showed that after surgical remission of endogenous hypercortisolism, duration of postoperative AI was longer in CS compared to MACS. Additionally, higher biochemical hypercortisolism severity score and a longer duration of symptoms suggestive of hypercortisolism were associated with a longer duration of postoperative AI.

Background: Hypoparathyroidism (HypoPT) is a rare endocrine disorder that requires close evaluation and follow up during pregnancy to minimize maternal and fetal complications. The primary objectives of this study are to evaluate the use of rhPTH (1-84) during pregnancy by analyzing data from the PARADIGHM disease registry, and to compare maternal and neonatal outcomes among patients who continued PTH therapy during pregnancy versus those on conventional therapy (CT). Methods: We performed a retrospective analysis of data in the PARADIGHM registry. Maternal and neonatal outcomes in women treated with rhPTH (1-84) were compared to women who received CT. Results: We analyzed 39 pregnancies of 32 women. Of those, 4 women (6 pregnancies) used rhPTH (1-84) either before or during pregnancy and 28 women (33 pregnancies) continued CT during pregnancy. The mean (SD) maternal age at enrollment was 31.7 (5.6) years. Postsurgical HypoPT was the most common etiology (68.8%). The mean gestational age at delivery was 36 (2.4) weeks (PTH-treated) vs 38.3 (3.3) weeks (CT) (p=0.162). Preterm delivery rates were higher in the PTH-treated group (50% vs. 27%, p=0.591), but this was not statistically significant. Two women had pre-eclampsia, one in each group (PTH-treated and CT). In the PTH-treated group, one pregnancy resulted in a stillbirth, and one infant was born with congenital anomalies (16.7% each). Conclusions: The safety of rhPTH (1-84) use in pregnancy cannot be determined at this time. The PTH-treated group exhibited trends towards higher rates of preterm delivery, but the rates of stillbirth, and congenital anomalies were low and comparable in both groups of women. Larger studies are necessary to determine the optimal approach to manage women with HypoPT during pregnancy. Presentation: Sunday, July 13, 2025

Meditation may be an effective intervention to alleviate the severity of GWS. Objective: To determine the acceptability of portable, wearable EEG device for guided meditation (MUSE headband) and the impact of MUSE use on GWS and quality of life 12 weeks post-surgery. Methods: We conducted a single-center prospective cohort study of adults with endogenous hypercortisolism undergoing curative surgery, 2019-2024. Patients had baseline and post-surgical assessments over 12 weeks. The study comprised of patients using MUSE for ≥ 6 weeks (MUSE cohort) and patients matched by age, sex, BMI, hypercortisolism type, and glucocorticoid type at 1:4 ratio. Quality of life and symptoms of GWS were assessed with AddiQoL, Cushing Quality of Life, and Short Form-36 mental and physical component (SF-36 MCS and PCS) questionnaires. Results: MUSE was offered to 52 patients, and 22 (42%) used MUSE for ≥ 6 weeks within 12 weeks post-surgery. At baseline, when compared to 88 matched subjects, 22 MUSE participants demonstrated a similar prevalence of comorbidities, clinical and biochemical hypercortisolism severity, but lower AddiQoL (mean 73 vs 66, P=0.031) and SF-36 MCS (mean 39 vs 33, P=0.022). At 12 weeks, these differences in quality of life were no longer present. After adjusting for age, sex, BMI, clinical severity score, and baseline quality of life, MUSE use was an independent predictor of improved SF- 36 PCS at 12 weeks post-surgery (beta 4.2, 95% CI: 0.5-7.9, P=0.026). Conclusions: Meditation intervention post-surgery may improve symptoms of GWS and accelerate recovery. Presentation: Sunday, July 13, 2025
