RESEARCH DESIGN AND METHODS A two-arm, parallel group, pragmatic randomized controlled trial. Adults with diabetes distress (20-item Problem Areas in Diabetes [PAID] score ≥25, or ≥2 on three or more items) were recruited via the National Diabetes Services Scheme (NDSS) and randomized (1:1) via central randomization by computer to LISTEN (maximum four sessions of problem-solving therapy) or usual care (web-based resources about diabetes and emotional health). Participants completed self-report online surveys at baseline and at 8 and 26 weeks. The primary outcome was the change in diabetes distress (PAID) from baseline to 26 weeks. Secondary outcomes included psychological distress (10-item Kessler Psychological Distress Scale), general emotional well-being (World Health Organization 5-item Well-being Index) and coping self-efficacy at 8 and 26 weeks. Data were analyzed using intention-to-treat principles. RESULTS Participants (n = 429, 59% women, 40% men, 1% nonbinary; median age 54 [interquartile range 42.0–63.5]; 37% type 1 diabetes, 63% type 2 diabetes) were enrolled and randomized to the intervention (n = 216) or control group (n = 213). Over 26 weeks, there was a greater reduction in diabetes distress among the LISTEN group versus the control group (mean difference −7.2 [95% CI −11.6, −2.8]; P < 0.001; Cohen f2 = 0.03) and greater improvements in general emotional well-being and coping self-efficacy. No adverse events were reported. CONCLUSIONS LISTEN is an effective, low-intensity program, addressing the unmet needs of adults with type 1 and type 2 diabetes experiencing mild-to-moderate diabetes distress.","PeriodicalId":11140,"journal":{"name":"Diabetes Care","volume":"18 1","pages":"955-965"},"PeriodicalIF":16.2,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144104702","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}

PURPOSE To systematically review existing evidence on cost-effectiveness of semaglutide versus other T2D medications. DATA SOURCES PubMed, Embase, and the Cost-Effectiveness Analysis Registry (by 11 June 2024). STUDY SELECTION A total of 45 articles (with 119 comparisons) from 2019 onward were included, representing Europe (n = 24), North America (n = 13), and Asia (all from China) (n = 8). DATA EXTRACTION Study characteristics and model characteristics/inputs/results were extracted. Lifetime costs and quality-adjusted life-years were evaluated. Proportions for cost-effectiveness outcomes (dominant, cost-effective, not cost-effective) were calculated. Subgroup analyses by region, sponsor type, comparator type, and model assumptions were performed. In sensitivity analysis a standard willingness-to-pay threshold was applied. DATA SYNTHESIS Of the articles included, 93.3% included adoption of a lifetime horizon and 84.4% a health care perspective and 68.9% were industry sponsored. For most studies reporting quality was high (86.7%). Overall, semaglutide was dominant/cost-effective in 73.9% of all comparisons. Notably, semaglutide was found to be dominant/cost-effective in all comparisons sponsored by Novo Nordisk versus in 50.0% of these funded by nonindustry sponsors and in none funded by other industry sponsors. Additionally, semaglutide was more cost-effective in high-income countries and in studies with adoption of a broader perspective, longer horizon, and lower discount rates. Results remained consistent with conversion with a common currency unit and willingness-to-pay threshold of US$50,000. LIMITATIONS Less detailed demographic information for more granular analyses. CONCLUSIONS Semaglutide is generally cost-effective compared with other glucose-lowering medications in evaluation against within-study willingness-to-pay thresholds; however, results varied by study sponsor type, region, and model assumptions, highlighting the need for transparent and context-sensitive economic evaluations.","PeriodicalId":11140,"journal":{"name":"Diabetes Care","volume":"129 1","pages":"1032-1041"},"PeriodicalIF":16.2,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144104696","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 We defined circulating metabolomic signatures of insulin action/secretion in 446 IAs, including glucose disposal rate during low-dose insulin clamp (Mlow) and endogenous glucose production (EGP) during insulin infusion (suppression of hepatic glucose production). We then determined associations of these metabolic scores with glucose tolerance (in a separate set of ∼700 IAs) and diabetes/metabolic risk in ∼2,000 individuals (from Coronary Artery Risk Development in Young Adults [CARDIA] study). We used tissue-specific gene–metabolite mapping to pinpoint genetic pathways of type 2 diabetes (T2D) implicated by metabolomic signatures. RESULTS In young IAs (mean age 29 years; mean BMI 34.9 kg/m2) without diabetes, phenotype–metabolome associations across multiple insulin action phenotypes were linked to mechanisms of fatty acid and amino acid metabolism and inflammation (among others). Metabolite-based scores of insulin action were strongly related to incident diabetes in our discovery IA population (Mlow; 49 metabolites; standardized hazard ratio [HR] 0.49; 95% CI 0.35–0.69; P < 0.0001) and also associated with measures of insulin resistance in a distinct IA population (|ρ| ∼0.3–0.5 correlation) and in the CARDIA group (median age 33 years).

PURPOSE We performed a meta-analysis of observational cohort studies to quantify the magnitude of the association between SGLT2 inhibitor use and risk of developing MALOs for people with type 2 diabetes mellitus (T2DM). DATA SOURCES We systematically reviewed three large electronic databases from inception to January 2025. STUDY SELECTION We included active-comparator, new-user cohort studies with comparison of SGLT2 inhibitors versus other glucose-lowering medications in patients with T2DM. DATA EXTRACTION The primary outcome was incidence rate of MALOs defined as a composite of hepatic decompensation events, hepatocellular carcinoma, liver transplantation, or liver-related deaths. Secondary outcomes included each of the above as individual events. Meta-analysis was performed with random-effects models. DATA SYNTHESIS We identified eight cohort studies with aggregate data on 626,104 patients with T2DM (397,806 SGLT2 inhibitor new users and 228,298 new users of other glucose-lowering agents). During a median of 2.7 years, SGLT2 inhibitor use was associated with significantly lower risk of MALOs (random-effects hazard ratio 0.83, 95% CI 0.72–0.95; I2 = 83.1%) and liver-related deaths (0.64, 0.50–0.82; I2 = 0%). The significant risk reduction in MALOs was observed in comparisons of SGLT2 inhibitors with dipeptidyl peptidase 4 inhibitors, metformin, or pioglitazone but not glucagon-like peptide 1 receptor agonists. Sensitivity analyses did not modify these results. A funnel plot did not show significant publication bias.

RESEARCH DESIGN AND METHODS A total of 1,557 participants from the San Antonio Heart Study who were free of type 2 diabetes at baseline, had a baseline OGTT, and had a repeat OGTT after 7.5 years of follow-up were evaluated. The ability of 1-h PG concentration to predict the development of prediabetes, based on American Diabetes Association criteria, was evaluated. RESULTS Approximately one-quarter of participants with NGT (24.7%) progressed to prediabetes at 7.5 years (22.5% with 1-h PG <155 mg/dL and 42.5% with 1-h PG >155 mg/dL). The 1-h PG was the strongest predictor of developing prediabetes, and a 1-h cut point of 120 mg/dL had 61% sensitivity and 67% specificity in identifying individuals with NGT at high risk of developing prediabetes. Participants with a 1-h PG of 120–155 mg/dL and who experienced a deterioration in glucose tolerance (progression to prediabetes) at follow-up were characterized by severe insulin resistance and metabolic abnormalities characteristic of the insulin resistance syndrome. Therefore, we suggest the term pre-prediabetes for this group to emphasize their high future risk of deteriorating glucose tolerance. CONCLUSIONS An increase in 1-h PG concentration precedes the development of prediabetes and identifies individuals with a 1-h PG of 120–155 mg/dL who are at increased risk of developing prediabetes.

The cumulative effects of this changing landscape on CF–related diabetes (CFRD) are unclear. We examined trends in CFRD epidemiology over time using data from the U.S. Cystic Fibrosis Foundation Patient Registry (CFFPR). RESEARCH DESIGN AND METHODS CFFPR data from 2003 to 2018 were queried to determine annual screening, incidence, and prevalence rates of CFRD. Individuals with incident CFRD were compared with individuals without CFRD. Survival analyses were performed to estimate the cumulative hazard of CFRD given predictors of interest over the 15 years of study. Data were also grouped into three time periods (2003–2008, 2009–2013, and 2014–2018) to investigate whether the hazard of developing CFRD varied over time. RESULTS CFRD screening rates increased from 2003 to 2018, particularly in 10- to 18-year-olds. Although screening rates increased in adults, overall rates remained low. In 10- to 18-year-olds, the incidence of CFRD was stable over time, while incident cases in adults steadily decreased, approaching incident rates in adolescents. Despite this, the prevalence of CFRD has gradually increased in adults, likely reflecting increased longevity. Age, female sex, Black race, severe mutation class, liver disease, poorer lung function, pancreatic insufficiency, enteric feeds, and low and high BMI were all risk factors associated with CFRD.

In a subsample with gut microbiota data during a follow-up visit (2016–2018), we examined gut microbial species associated with serum ImP and their potential interactions with dietary intake. RESULTS Serum ImP and ImP-to-histidine ratio were positively associated with incident T2D (hazard ratio [95% CI] = 1.17 [1.00–1.36] and 1.33 [1.14–1.55], respectively, comparing highest and lowest tertiles), whereas histidine was inversely associated with incident T2D (hazard ratio = 0.75 [95% CI 0.64–0.86]). A higher amount of fiber intake was associated with lower serum ImP level and ImP-to-histidine ratio, whereas histidine intake was not associated with serum ImP level in the overall sample. Fifty-three bacterial species, including 19 putative ImP producers, were associated with serum ImP. Histidine intake was positively associated with serum ImP and ImP-to-histidine ratio only in participants with a high ImP-associated gut microbiota score (P = 0.03 and 0.02, respectively, for interaction). The associations of fiber intake with serum ImP and ImP-to-histidine ratio were partly mediated by ImP-associated gut microbiota (proportion mediated = 31.4% and 19.8%, respectively).

Randomized clinical trials have demonstrated that lifestyle modification is cost-effective in preventing diabetes. Implementation studies showed the feasibility of delivering real-world structured lifestyle modification programs adapted from the U.S. Diabetes Prevention Program trial. However, the current approach to diabetes prevention in the U.S. has been largely inadequate thus far, as evidenced by the stagnant numbers of people with prediabetes and the growing number of those with diabetes. The many gaps in the implementation of the National Diabetes Prevention Program (NDPP) can be characterized as due to macro-level barriers (failures of pay-for-performance reimbursement, an undersupply of lifestyle change programs), micro-level barriers (low and disparate reach, low referral and retention rates in the program), variable fidelity in implementation, and limitations of a one-size-fits-all intervention. All of these issues point to a need for reexamining strategies for diabetes prevention in the U.S., which is yet to show benefits or value at the population level. This article details how prediabetes is currently suboptimally addressed in clinical practice and communities in the U.S. and articulates why there is an urgent need to rethink our approach to addressing prediabetes, possibly through integration of synergistic individual- and societal-levels approaches.","PeriodicalId":11140,"journal":{"name":"Diabetes Care","volume":"12 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920104","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}
