Whether these benefits are consistent across diabetes-related characteristics remains unclear. RESEARCH DESIGN AND METHODS The primary outcome was the ratio to baseline (ETR) in maximum walking distance (MWD), with pain-free walking distance (PFWD) as a key secondary end point. Both were measured at 52 weeks using a constant load treadmill. Subgroup analyses were performed by diabetes duration, BMI, HbA1c, and diabetes medications. A mixed model for repeated measurements was used, incorporating treatment, region, and subgroup as fixed factors, and baseline value as covariate, along with the treatment-by-subgroup interaction. RESULTS Among 792 participants (median diabetes duration 12.2 years, HbA1c 7.1%, and BMI 28.7 kg/m2), 35.1% used sodium–glucose cotransporter 2 inhibitors and 31.7% used insulin. Semaglutide significantly improved MWD regardless of diabetes duration (ETR of 1.15 vs. 1.13 for <10 vs. ≥10 years, P = 0.80), BMI (1.12 vs. 1.16 for <30 vs. ≥30 kg/m2, P = 0.58), HbA1c (1.13 for <7% and ≥7%, P = 0.99), or medication use. Semaglutide also improved PFWD across subgroups (P > 0.1 for all interactions). BMI reduction correlated weakly with MWD improvements and was more pronounced in the controls with higher baseline BMI. Safety outcomes were consistent across subgroups. CONCLUSIONS Semaglutide improved walking function in people with PAD and type 2 diabetes, including nonobese individuals and those with well-controlled HbA1c. Benefits were consistent across BMI and HbA1c categories, supporting effectiveness beyond weight or glycemic changes.","PeriodicalId":11140,"journal":{"name":"Diabetes Care","volume":"26 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144337510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By virtue of the many elements required for optimal care, the poor diabetes care quality and outcome metrics of the U.S. are canaries in the coal mine for the health care system. The fundamental problem with the U.S. health care system is that it does not prioritize the long-term health and well-being of all individuals and communities. Three intertwined elements are foundational for an understanding of why the U.S. health care system is built the way it is and what changes are necessary to improve it: 1) ethics and culture; 2) political economy, the underlying political and economic structures that shape our nation and thus our health system; and 3) the definition and measurement of value in health care. This article recommends that health care policies around health insurance and payment be designed to support, incentivize, and sustain effective population health models that address medical, social, psychological, and behavioral needs of all individuals and communities. Good governance is essential to assure that payer and provider market incentives are explicitly aligned to prioritize the health and well-being of individuals and communities and cost-effectiveness of care, beyond short-term financial gain for health care systems and investors. Equitable access allows for health care resource distribution according to need, enabling all individuals to have a fair and just opportunity for health.","PeriodicalId":11140,"journal":{"name":"Diabetes Care","volume":"5 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144337512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RESEARCH DESIGN AND METHODS This observational cohort study used U.K. Clinical Practice Research Datalink GOLD data linked to hospital and death records. Older adults (≥70 years) with T2D, identified between 2000 and 2017, were considered exposed if they had three consecutive HbA1c measurements <7% (53 mmol/mol) while receiving treatment with insulin or sulfonylureas. Each exposed individual was matched with to three nonexposed individuals. Outcomes included hospitalizations for falls and fractures. Flexible parametric survival models, adjusted for sociodemographic and clinical factors, and associated estimated relative (hazard ratio [HR]) and absolute risks. RESULTS Among 21,365 individuals (n = 5,833 [27.3%] in the exposed group), the adjusted relative risks of hospitalization for falls and fractures were marginally higher compared with those nonexposed (HR 1.04 [95% CI 0.96–1.11] and 1.07 [95% CI 0.97–1.17], respectively). The 10-year absolute risk values of hospitalization for falls were slightly higher in the exposed (range 15.6–36.8% in those aged 70–85 years) than nonexposed (15.1–36.0%) individuals. Absolute risk differences remained minimal (0.2–0.6% at 5 years and 0.5–0.8% at 10 years). CONCLUSIONS We found no evidence of an association between sustained HbA1c <7% while receiving insulin or sulfonylurea therapy and clinically meaningful increased risks of falls or fractures in older adults with T2D.

Herman, Shihchen Kuo","doi":"10.2337/dci24-0103","DOIUrl":"https://doi.org/10.2337/dci24-0103","url":null,"abstract":"The American Diabetes Association (ADA) publishes the “Standards of Care in Diabetes” (SOC) annually to offer clinicians, patients, and payers evidence-based guidelines for diabetes management. The 2025 SOC recommends that clinicians consider screening asymptomatic adults with diabetes for heart failure using natriuretic peptide levels, and that they screen asymptomatic adults with diabetes ≥65 years of age with any microvascular disease, foot complications, or end-organ damage from diabetes for peripheral artery disease (PAD) using ankle-brachial index (ABI) testing. This perspective evaluates those recommendations using established screening principles and the published literature. The recommendation to screen for heart failure using natriuretic peptide lacks robust evidence in several key areas. N-terminal pro-B-type natriuretic peptide, or NT-proBNP, itself performs poorly as a screening test in asymptomatic adults. Furthermore, there is ambiguity in treatment recommendations and insufficient evidence showing improved outcomes with sodium–glucose cotransporter 2 inhibitor treatment in adults with diabetes and stage B heart failure. Finally, the costs involved are high and may not be economically justifiable. Similarly, the recommendation to screen for PAD in asymptomatic adults with diabetes is not backed by rigorous scientific evidence. The evidence cited combines ABI screening with other effective screening tests and has limited generalizability. There is no guidance on how to interpret the results of ABI testing or how the information gained should be used to direct treatment. While the intent to improve health care through screening is commendable, these recommendations are inadequately supported by the principles of screening and the published literature. It is imperative that the ADA uses the greatest scientific rigor to prepare its SOC.","PeriodicalId":11140,"journal":{"name":"Diabetes Care","volume":"7 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144278335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RESEARCH DESIGN AND METHODS In a retrospective cohort study of 6,690 patients with obesity and type 2 diabetes who underwent bariatric surgery in 2012–2019 and 19,122 matched nonsurgical patients, we compared total, outpatient, inpatient, and medication expenditures 3 years presurgery and 5.5 years postsurgery, using generalized estimating equations. Expenditures were estimated in 6-month intervals. RESULTS Surgical and nonsurgical cohorts were well-matched, with 73% female, average BMI 44 kg/m2, mean age 50 years, and 32% on insulin. Estimated total expenditures were similar between surgical and nonsurgical patients up to 1 year presurgery. Total expenditures were significantly lower for surgical patients starting 1 year postsurgery and up to 5.5 years postsurgery compared with controls ($566 lower per 6-month interval at 5.5 years; 95% CI −$807, −$316).

CONCLUSIONS Changing the screening approach substantially increased diagnoses of lifestyle-treated GDM but did not impact medication-treated GDM or infant birth weight.","PeriodicalId":11140,"journal":{"name":"Diabetes Care","volume":"11 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144218875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
