Background Shock‐reduction implantable cardioverter‐defibrillator programming (SRP) was associated with fewer therapies and improved survival in randomized controlled trials, but real‐world studies investigating SRP and associated outcomes are limited. Methods and Results The BIOTRONIK CERTITUDE registry was linked with the Medicare database. We included all patients with an implantable cardioverter‐defibrillator implanted between August 22, 2012 and September 30, 2021 in the United States. SRP was defined as programming to either a therapy rate cutoff ≥188 beats per minute or number of intervals to detection ≥30/40 for treatment. Among 6781 patients (mean 74±9 years; 27% women), 3393 (50%) had SRP. Older age, secondary prevention indication, and device implantation in the southern or western United States were associated with lower use of SRP. The cumulative incidence rate of implantable cardioverter‐defibrillator shocks was lower in the SRP group (5.1% shocks/patient year) compared with the non‐SRP group (7.2% shocks/patient year) (adjusted hazard ratio [HR], 0.83 [95% CI, 0.73–0.96]; P =0.005). Over a median follow‐up of 2.9 years, 739 deaths occurred in the SRP group and 822 deaths occurred in the non‐SRP group (adjusted HR, 0.97 [95% CI, 0.88–1.07]; P =0.569). SRP was associated with a lower all‐cause mortality among patients without ischemic heart disease compared with patients with ischemic heart disease (adjusted HR, 0.64 [95% CI, 0.48–0.87] versus adjusted HR, 1.02 [95% CI, 0.92–1.14]; P interaction =0.004). Conclusions Adoption of SRP is low in real‐world clinical practice. Age, clinical variables, and geographic factors are associated with use of SRP. In this study, SRP‐associated decrease in mortality was limited to patients without ischemic heart disease.

Hypertension is among the most important risk factors for cardiovascular disease, chronic kidney disease, and dementia. The artificial intelligence (AI) field is advancing quickly, and there has been little discussion on how AI could be leveraged for improving the diagnosis and management of hypertension. AI technologies, including machine learning tools, could alter the way we diagnose and manage hypertension, with potential impacts for improving individual and population health. The development of successful AI tools in public health and health care systems requires diverse types of expertise with collaborative relationships between clinicians, engineers, and data scientists. Unbiased data sources, management, and analyses remain a foundational challenge. From a diagnostic standpoint, machine learning tools may improve the measurement of blood pressure and be useful in the prediction of incident hypertension. To advance the management of hypertension, machine learning tools may be useful to find personalized treatments for patients using analytics to predict response to antihypertension medications and the risk for hypertension-related complications. However, there are real-world implementation challenges to using AI tools in hypertension. Herein, we summarize key findings from a diverse group of stakeholders who participated in a workshop held by the National Heart, Lung, and Blood Institute in March 2023. Workshop participants presented information on communication gaps between clinical medicine, data science, and engineering in health care; novel approaches to estimating BP, hypertension risk, and BP control; and real-world implementation challenges and issues.

Abstract Clonal cytopenia of undetermined significance (CCUS) represents a distinct disease entity characterized by myeloid-related somatic mutations with a variant allele fraction of ≥2% in individuals with unexplained cytopenia(s) but without a myeloid neoplasm (MN). Notably, CCUS carries a risk of progressing to MN, particularly in cases featuring high-risk mutations. Understanding CCUS requires dedicated studies to elucidate its risk factors and natural history. Our analysis of 357 patients with CCUS investigated the interplay between clonality, cytopenia, and prognosis. Multivariate analysis identified 3 key adverse prognostic factors: the presence of splicing mutation(s) (score = 2 points), platelet count of <100 × 109/L (score = 2.5), and ≥2 mutations (score = 3). Variable scores were based on the coefficients from the Cox proportional hazards model. This led to the development of the clonal cytopenia risk score (CCRS), which stratified patients into low- (score of <2.5 points), intermediate- (score of 2.5 to <5), and high-risk (score of ≥5) groups. The CCRS effectively predicted 2-year cumulative incidence of MN for low- (6.4%), intermediate- (14.1%), and high-risk (37.2%) groups, respectively, by the Gray test (P < .0001). We further validated the CCRS by applying it to an independent CCUS cohort of 104 patients, demonstrating a c-index of 0.64 (P = .005) in stratifying the cumulative incidence of MN. Our study underscores the importance of integrating clinical and molecular data to assess the risk of CCUS progression, making the CCRS a valuable tool that is practical and easily calculable. These findings are clinically relevant, shaping the management strategies for CCUS and informing future clinical trial designs.

PURPOSE Long-term outcomes of patients with stage I human epidermal growth factor receptor 2 (HER2)–positive breast cancer receiving adjuvant trastuzumab emtansine (T-DM1) remain undefined, and prognostic predictors represent an unmet need. METHODS In the ATEMPT phase II trial, patients with stage I centrally confirmed HER2-positive breast cancer were randomly assigned 3:1 to adjuvant T-DM1 for 1 year or paclitaxel plus trastuzumab (TH). Coprimary objectives were to compare the incidence of clinically relevant toxicities between arms and to evaluate invasive disease-free survival (iDFS) with T-DM1. Correlative analyses included the HER2DX genomic tool, multiomic evaluations of HER2 heterogeneity, and predictors of thrombocytopenia. RESULTS After a median follow-up of 5.8 years, 11 iDFS events were observed in the T-DM1 arm, consistent with a 5-year iDFS of 97.0% (95% CI, 95.2 to 98.7). At 5 years, the recurrence-free interval (RFI) was 98.3% (95% CI, 97.0 to 99.7), the overall survival was 97.8% (95% CI, 96.3 to 99.3), and the breast cancer-specific survival was 99.4% (95% CI, 98.6 to 100). Comparable iDFS was observed with T-DM1 irrespective of tumor size, hormone receptor status, centrally determined HER2 immunohistochemical score, and receipt of T-DM1 for more or less than 6 months. Although ATEMPT was not powered for this end point, the 5-year iDFS in the TH arm was 91.1%. Among patients with sufficient tissue for HER2DX testing (n = 187), 5-year outcomes significantly differed according to HER2DX risk score, with better RFI (98.1% v 81.8%, hazard ratio [HR], 0.10, P = .01) and iDFS (96.3% v 81.8%, HR, 0.20, P = .047) among patients with HER2DX low-risk versus high-risk tumors, respectively. CONCLUSION Adjuvant T-DM1 for 1 year leads to outstanding long-term outcomes for patients with stage I HER2-positive breast cancer. A high HER2DX risk score predicted a higher risk of recurrence in ATEMPT.

Background/Objective: Clostridioides difficile infection (CDI) is a common healthcare-associated ailment, presenting major health and economic challenges, especially for the elderly. Despite its prevalence, comprehensive data about CDI’s impact on the elderly are limited. Methods: This study used the Global Burden of Disease Study 2019 data to analyze CDI trends from 2000 to 2019, considering factors like sex, region, and sociodemographic index (SDI). Results: This study revealed that CDI caused approximately 18,181 deaths and 252,709 disability-adjusted life years (DALYs) among the elderly worldwide. The Americas showed the highest CDI burden, while the Eastern Mediterranean saw the steepest rate increase from 2000 to 2019. Regions with a high SDI also displayed substantial CDI impact. Conclusions: The escalating burden of CDI in the elderly, especially in high-SDI areas and the Americas, emphasizes an urgent need for targeted public health strategies.

Abstract We evaluate the impact of donor types on outcomes of hematopoietic cell transplantation (HCT) in myelofibrosis, using the Center for International Blood and Marrow Transplant Research registry data for HCTs done between 2013 and 2019. In all 1597 patients, the use of haploidentical donors increased from 3% in 2013 to 19% in 2019. In study-eligible 1032 patients who received peripheral blood grafts for chronic-phase myelofibrosis, 38% of recipients of haploidentical HCT were non-White/Caucasian. Matched sibling donor (MSD)–HCTs were associated with superior overall survival (OS) in the first 3 months (haploidentical hazard ratio [HR], 5.80 [95% confidence interval (CI), 2.52-13.35]; matched unrelated (MUD) HR, 4.50 [95% CI, 2.24-9.03]; mismatched unrelated HR, 5.13 [95% CI, 1.44-18.31]; P < .001). This difference in OS aligns with lower graft failure with MSD (haploidentical HR, 6.11 [95% CI, 2.98-12.54]; matched unrelated HR, 2.33 [95% CI, 1.20-4.51]; mismatched unrelated HR, 1.82 [95% CI, 0.58-5.72]). There was no significant difference in OS among haploidentical, MUD, and mismatched unrelated donor HCTs in the first 3 months. Donor type was not associated with differences in OS beyond 3 months after HCT, relapse, disease-free survival, or OS among patients who underwent HCT within 24 months of diagnosis. Patients who experienced graft failure had more advanced disease and commonly used nonmyeloablative conditioning. Although MSD-HCTs were superior, there is no significant difference in HCT outcomes from haploidentical and MUDs. These results establish haploidentical HCT with posttransplantation cyclophosphamide as a viable option in myelofibrosis, especially for ethnic minorities underrepresented in the donor registries.

Abstract Introduction Sexual well-being is an important quality of life component to women throughout life, and during menopausal transition and beyond. Female sexual response cycle includes desire, arousal, orgasm, and resolution phases. Female sexual dysfunction (FSD) encompasses all phases of sexual response cycle and can lead to distress for both the woman and her partner and warrant further investigation. Research has indicated both positive and negative associations between alcohol consumption and sexual health, our review goal is to further explore the relationship between alcohol consumption and sexual function in perimenopausal women. Objective We aim to review the current literature regarding the influence of alcohol use on sexual health during the menopausal transition and beyond. Methods The examination of alcohol consumption and its effects on sexual health in menopausal women was performed through reviewing existing literature. The literature search was completed in the Ovid MEDLINE database (1946- Present) in August 2023. 16 articles were identified in the initial search. 12 articles met our inclusion criteria and were independently reviewed by the authors. Results from these articles were summarized. The search was limited to the English language and the last 20 years (2003-current). Keywords included: menopause, pre-menopause, post menopause, perimenopause, alcohol use, alcohol related disorder, and sexual function. Results Seven out of 16 articles reviewed linked a negative association between alcohol consumption and female sexual function. Seven indicated a positive association between alcohol use and sexual function and 2 articles did not reveal an association. The findings of our review indicate a complex relationship of alcohol on women's sexual function. Studies indicating a positive association between mild alcohol consumption (equal or less than 0.21 FL oz. alcohol/day) and improved sexual function. This effect was theorized due to alcohol increasing endogenous estrogen or due to behavioral changes such as disinhibition, influencing sexual activities influenced by alcohol or subjective arousal due to drinking. Additionally, a positive association was seen between increased alcohol consumption and Female Sexual Function Index (FSFI) scores. However no significant influence on Female Sexual Distress Scale scoring was identified which is a key component to FSD. Other studies showed that excessive or prolonged alcohol consumption (more than 1.00 FL oz. alcohol per day) found to be associated with worsening sexual function and can impact all 6 domains on the FSFI (which include: desire, arousal, lubrication, orgasm, satisfaction, and pain) even after abstinence. These findings were reflected in another study that showed women (however not exclusively menopausal) who were seeking treatment for alcohol dependency diagnosis experienced low sexual desire, inability to achieve orgasm and less satisfaction. Initiating alcohol consumption at a younger age, along with an extended and more intense period of dependency, was correlated with a higher likelihood of experiencing increased sexual dysfunction. A meta-Analysis of 7 studies showed increased odds of sexual dysfunction with alcohol consumption. Another study showed that moderate alcohol consumption was found to be an independent risk factor for FSD and Genitourinary syndrome of menopause (GSM) which can lead to FSD. Conclusions The impact of alcohol on sexual health in postmenopausal women is multifaceted, based on varying levels of consumption influencing various aspects of sexual function. This relationship can also be influenced by other factors such as pre-existing sexual problems and the utilization of alcohol as a coping mechanism to reduce anxiety, release stress or to increase sexual behavior through enhancing arousal. A study indicated that menopausal symptoms may trigger a craving for alcohol, leading to increased alcohol consumption. Further research is essential to elucidate the direct and indirect effects of alcohol consumption on sexual dysfunction. In addition, the impact of abstinence from alcohol on sexual dysfunction in postmenopausal women needs to be further explored. Understanding the impact of alcohol consumption on sexual function of postmenopausal women is critical for healthcare professionals, to provide appropriate guidance and interventions. These findings highlight the need for further research and increased awareness regarding the impact of alcohol use on sexual health during in pre-menopausal, peri and postmenopausal women.

10026 Background: Childhood cancer survivors are at high risk for developing subsequent breast cancer with higher mortality than females in the general population with primary breast cancer. Whether therapeutic tradeoffs in treating primary versus subsequent breast cancer alter survival is unknown. Methods: Breast cancer treatment data were abstracted from medical records for female survivors from the CCSS and a multi-institutional sample of females with primary breast cancer matched one-to-one by demographics, diagnosis age/year, and breast cancer characteristics. Survivors’ excess mortality risk was evaluated as hazard ratios (HRs), adjusting for receipt of historically-appropriate guideline-concordant treatment established for primary breast cancer. Results: Subsequent breast cancers were diagnosed between 1981-2016 among 431 survivors, with a median diagnosis age of 40 years (IQR: 35-44). Most subsequent breast cancers were invasive (77%), with hormone receptor profiles similar to the general population (78% ER-positive; 26% HER2-positive). Guideline-concordant breast cancer treatment did not differ between survivors and controls (N = 688; 94% versus 93%), but treatment selection differed, reflecting survivors’ complex clinical history and guidelines’ multiple treatment options. Anthracyclines were used in 47% of survivors (controls 66%), mastectomy in 81% of survivors (controls 60%), and radiotherapy in 18% of survivors (controls 61%). In the subgroup treated with surgery and chemotherapy (survivors 31%, controls 26%), survivors did not have greater likelihood of dose reductions or omissions, treatment delays, or hospitalization for fever and neutropenia, but they were more likely to experience hematological toxicities (21% vs. 9%, p = 0.033) and other organ system-specific toxicities (36% vs. 11%, p < 0.001). Over one-third (38%) of survivors died during follow-up (median follow-up 9 years, IQR 6-14) after breast cancer. Strikingly higher all-cause mortality was observed among survivors than controls (HR = 3.5, 95% CI 2.2-5.6), especially after in situ disease (HR = 9.9, 95% CI 2.2-44.2). Among survivors with invasive disease, breast cancer accounted for most deaths (51%), followed by other subsequent malignancies (15%) and cardiovascular diseases (15%). Other health conditions accounted for 67% of deaths following in situ disease. Conclusions: Childhood cancer survivors with subsequent breast cancer generally receive guideline-concordant breast cancer treatment. While the treatments survivors receive differ from females with primary breast cancer, they do not experience higher rates of on-therapy treatment modifications. Despite this, they face excess mortality, primarily driven by other health conditions. Managing comorbidities is critical to enhancing long-term survival for this high-risk population.
