Objective: Underserved young adults (YA) with type 1 diabetes (T1D) experience the worst outcomes across the life span. We developed and integrated the Supporting Emerging Adults with Diabetes (SEAD) program into routine endocrinology care to address unmet social and medical challenges., Research Design and Methods: This study was designed as a longitudinal cohort study, with prospective data collection over 4 years on YA in SEAD compared with usual endocrine care. We used propensity-weighted analysis to account for differences in baseline characteristics, and multivariate regression and Cox proportional hazard models to evaluate change in outcomes over time. Primary outcomes included incidence of hospitalizations, diabetes technology uptake, and annual change in HbA1c levels., Results: We included 497 YA with T1D in SEAD (n = 332) and usual endocrine care (n = 165); mean age 25 years, 27% non-Hispanic Black, 46% Hispanic, 49% public insurance, mean HbA1c 9.2%. Comparing YA in SEAD versus usual care, 1) incidence of hospitalizations was reduced by 64% for baseline HbA1c >9% (HR 0.36 [0.13, 0.98]) and 74% for publicly insured (HR 0.26 [0.07, 0.90]); 2) automated insulin delivery uptake was 1.5-times higher (HR 1.51 [0.83, 2.77]); and 3) HbA1c improvement was greater (SEAD, -0.37% per year [-0.59, -0.15]; usual care, -0.26% per year [-0.58, 0.05])., Conclusions: SEAD meaningfully improves clinical outcomes in underserved YA with T1D, especially for publicly insured and high baseline HbA1c levels. Early intervention for at-risk YA with T1D as they enter adult care could reduce inequity in short and long-term outcomes., (© 2024 by the American Diabetes Association.)

Background: A recent trial showed that postmenopausal women diagnosed with hormone receptor-positive, human epidermal growth factor receptor-2 (HER2)-negative, lymph node-positive (1-3 nodes) breast cancer with a 21-gene recurrence score of ≤ 25 could safely omit chemotherapy. However, there are limited data on population-level long-term outcomes associated with omitting chemotherapy among diverse women seen in real-world practice., Methods: We adapted an established, validated simulation model to generate the joint distributions of population-level characteristics of women diagnosed with early-stage breast cancer in the U.S. Input parameters were derived from cancer registry, meta-analyses, and clinical trial data. The effects of omitting chemotherapy on 10-year distant recurrence-free survival, life-years, and quality adjusted life-years (QALYs) were modeled for premenopausal and postmenopausal women. QALYs were discounted at 3%. Results were evaluated for subgroups stratified by race and ethnicity. Sensitivity analyses included testing results across a range of inputs. The model was validated using the published RxPONDER trial data., Results: In premenopausal women, the 10-year distant recurrence-free survival rates were 85.3% with chemo-endocrine and 80.1% with endocrine therapy. The estimated life-years and QALYs gained with chemotherapy in premenopausal women were 2.1 and 0.6, respectively. There was no chemotherapy benefit in postmenopausal women. There was no variation in the absolute benefit of chemotherapy across racial or ethnic subgroups. However, there were differences in distant recurrence-free survival rates, life-years, and QALYs across groups. Sensitivity analysis showed similar results. The model closely replicated the RxPONDER trial., Conclusions: Modeled population-level outcomes show a small chemotherapy benefit in premenopausal women, but no benefit among postmenopausal women. Simulation modeling provides a useful tool to extend trial data and evaluate population-level outcomes., (© 2024.

Objective: Diabetic foot ulcers (DFUs) are a leading cause of morbidity and mortality, which disproportionately impacts underserved populations. This study aimed to provide data regarding the rates and outcomes of amputation in patients admitted with DFU in our health system, which cares for an ethnically diverse and underserved population., Methods: This retrospective study examined the electronic medical records of adult patients hospitalized with DFU at 3 hospitals in our health system between June 1, 2016, and May 31, 2021., Results: Among 650 patients admitted with DFU, 88% self-identified as non-White race. Male sex (odds ratio [OR], 0.62), low body mass index (OR, 0.98), and history of smoking (OR, 1.45) were significantly associated with amputation during the study period. A higher erythrocyte sedimentation rate (OR, 1.01), C-reactive protein level (OR, 1.05), and white blood cell count (OR, 1.11) and low albumin level (OR, 0.41) were found to be significantly associated with amputation versus no amputation during admission. The amputation risk during the index admission for DFU was 44%., Conclusion: Our study identified a high DFU-related amputation risk (44%) among adult patients who were mostly Black and/or Hispanic. The significant risk factors associated with DFU amputation included male sex, low body mass index, smoking, and high levels inflammation or low levels of albumin during admission. Many of these patients required multidisciplinary care and intravenous antibiotic therapy, necessitating a longer length of stay and high readmission rate., Competing Interests: Disclosure The authors have no conflicts of interest to disclose., (Copyright © 2024 AACE.

Importance: Breast cancer mortality in the US declined between 1975 and 2019. The association of changes in metastatic breast cancer treatment with improved breast cancer mortality is unclear., Objective: To simulate the relative associations of breast cancer screening, treatment of stage I to III breast cancer, and treatment of metastatic breast cancer with improved breast cancer mortality., Design, Setting, and Participants: Using aggregated observational and clinical trial data on the dissemination and effects of screening and treatment, 4 Cancer Intervention and Surveillance Modeling Network (CISNET) models simulated US breast cancer mortality rates. Death due to breast cancer, overall and by estrogen receptor and ERBB2 (formerly HER2) status, among women aged 30 to 79 years in the US from 1975 to 2019 was simulated., Exposures: Screening mammography, treatment of stage I to III breast cancer, and treatment of metastatic breast cancer., Main Outcomes and Measures: Model-estimated age-adjusted breast cancer mortality rate associated with screening, stage I to III treatment, and metastatic treatment relative to the absence of these exposures was assessed, as was model-estimated median survival after breast cancer metastatic recurrence., Results: The breast cancer mortality rate in the US (age adjusted) was 48/100 000 women in 1975 and 27/100 000 women in 2019. In 2019, the combination of screening, stage I to III treatment, and metastatic treatment was associated with a 58% reduction (model range, 55%-61%) in breast cancer mortality. Of this reduction, 29% (model range, 19%-33%) was associated with treatment of metastatic breast cancer, 47% (model range, 35%-60%) with treatment of stage I to III breast cancer, and 25% (model range, 21%-33%) with mammography screening. Based on simulations, the greatest change in survival after metastatic recurrence occurred between 2000 and 2019, from 1.9 years (model range, 1.0-2.7 years) to 3.2 years (model range, 2.0-4.9 years). Median survival for estrogen receptor (ER)-positive/ERBB2-positive breast cancer improved by 2.5 years (model range, 2.0-3.4 years), whereas median survival for ER-/ERBB2- breast cancer improved by 0.5 years (model range, 0.3-0.8 years)., Conclusions and Relevance: According to 4 simulation models, breast cancer screening and treatment in 2019 were associated with a 58% reduction in US breast cancer mortality compared with interventions in 1975. Simulations suggested that treatment for stage I to III breast cancer was associated with approximately 47% of the mortality reduction, whereas treatment for metastatic breast cancer was associated with 29% of the reduction and screening with 25% of the reduction.
