We investigated whether initiation of SGLT2i, compared with glucagon-like peptide 1 receptor agonists (GLP-1RAs), was associated with an elevated risk of UTI and GTI in people with type 2 diabetes. RESEARCH DESIGN AND METHODS In this cohort study emulating a target trial, we included all adult metformin users initiating SGLT2i or GLP-1RAs in Denmark in 2016–2021 and used inverse-probability of treatment (IPT) weighting to balance potential confounders. We estimated IPT-weighted risk and risk ratios of community- or hospital-treated UTI and GTI, performing both intention-to-treat and on-treatment analyses. RESULTS This study included 52,414 SGLT2i initiators and 27,023 GLP-1RA initiators with a median follow-up of 2.9 to 3.9 years. The estimated risks of UTI within the first year were nearly identical: 10.0% in SGLT2i and 10.2% in GLP-1RAs in intention-to-treat analyses corresponding to a risk ratio of 0.98 (95% CI 0.94, 1.03). For GTI, the 1-year risks were elevated under SGLT2i therapy at 2.0% vs. 0.7% (risk ratio 2.95 [95% CI 2.52, 3.44]). During the 5-year follow-up, the relative UTI risk remained almost constant (0.96 [95% CI 0.94, 0.99]) whereas the GTI risk ratio with SGLT2is decreased to 1.64 (95% CI 1.49, 1.80). CONCLUSIONS In routine clinical care, SGLT2i initiation is not associated with increased risk of UTI compared with GLP-1RA initiation. However, early GTI risk is up to threefold larger in SGLT2i users.","PeriodicalId":11140,"journal":{"name":"Diabetes Care","volume":"183 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766479","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}

We paired continuous glucose monitoring (CGM) with ambulatory cognitive testing to examine bidirectional associations among adults with type 1 diabetes (T1D). RESEARCH DESIGN AND METHODS Participants wore blinded CGM and completed ambulatory tests of perceptual speed and sustained attention five or six times daily for 14 days. CGM metrics were calculated over 3-h periods (mean glucose, %time in range [70–180 mg/dL], %time in low [<70 mg/dL], %time in high [181–250 mg/dL], %time in very high [>250 mg/dL], and coefficient of variation). Immediate glucose values within 15 min of cognitive assessments were also examined. Dynamic structural equation models evaluated bidirectional relationships over sequential 3-h periods. RESULTS Among 182 diverse adults with T1D (age 40 ± 14 years, 46% male, 41% Latino, 29% White, 15% Black), more time in low glucose over 3 h was associated with slower perceptual speed at the end of that interval (P < 0.05) but not 3 h later. More time in high glucose (>250) was associated with faster perceptual speed initially but slower speed 3 h later (P < 0.05). Physical activity partially mediated the effect of high glucose on slower perceptual speed. Glycemia did not predict attention scores within persons. Lower attention and higher perceptual speed predicted higher mean glucose and more time in very high glucose over the following 3 h (P < 0.05). CONCLUSIONS These novel observations of significant bidirectional association between glycemia and cognitive performance over the course of the day among adults with T1D emphasize the importance of examining within-person longitudinal effects over different time frames.","PeriodicalId":11140,"journal":{"name":"Diabetes Care","volume":"1 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745076","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 study used an intervention comparison design with 12 intervention communities and 4 comparison communities matched according to location in urban or suburban areas. A community organization approach was used to integrate standardization of key messages and patient education protocols, along with adaptation and innovation among multiple community partners. The primary outcome was HbA1c; secondary outcomes included BMI, fasting plasma glucose (FPG), systolic and diastolic blood pressure, LDL cholesterol (LDL-C), depressive symptoms (PHQ-8), diabetes distress, and general quality of life (EQ-5D). RESULTS The analyses included 967 participants completing both the baseline and follow-up assessment. Intervention communities versus comparison communities were older (mean age 66.43 vs. 63.45 years), included more women (57.1% vs. 45.5%), and had longer diabetes duration (mean 7.95 vs. 6.40 years).

RESEARCH DESIGN AND METHODS We emulated a target trial comparing SGLT-2is and dipeptidyl peptidase 4 inhibitors (DPP-4is) based on the Yinzhou Regional Health Care Database. Cohorts of patients with type 2 diabetes mellitus who were new users of an SGLT-2i or a DPP-4i were assembled. Inverse probability of treatment weighting (IPTW) and Cox proportional hazards regression modeling were applied to estimate the hazard ratio (HR) and 95% CI of the association between use of SGLT-2is and incidence of epilepsy. RESULTS The final cohort included 24,930 new users of SGLT-2is and 28,924 initiators of DPP-4is. A total of 243 patients with incident epilepsy were found during a median follow-up of 2.0 (interquartile range 0.8–3.3) years, with the incidence of epilepsy being 174.2 and 231.5 per 100,000 person-years in users of SGLT-2is and DPP-4is, respectively. After controlling for potential confounding using IPTW, SGLT-2i use was associated with a lower incidence of epilepsy, with an HR of 0.71 (95% CI 0.52–0.97).

With the availability of glucagon-like peptide 1 receptor agonists and sodium–glucose cotransporter 2 inhibitors, basal insulin (BI) therapy is no longer the first-line option after lifestyle modification plus oral agents is insufficient. In contrast to BI, the newer medications require minor titration, lower hyperglycemia in a glucose-dependent manner, and reduce body weight. Importantly, the newer agents reduce cardiorenal events in the short term. Nonetheless, insulin therapy continues to play a key role in control of hyperglycemia and therefore long-term prevention of vascular complications. Its use is essential in many circumstances, including metabolic emergencies, new diabetes onset, latent autoimmune diabetes (LADA), pregnancy, and when other agents are less desirable due to comorbidities. BI is needed in the frequent condition of failure of other therapies to keep HbA1c to target and/or intolerance of them. There are several advantages to the combination of BI with the newer medications given their different but complementary mechanisms of action, primarily, the lower dose of each, improving adherence and outcomes while decreasing the side effects. Multiple choices for single or combination use can better meet the variety of clinical phenotypes in the heterogeneous T2DM population, using the tenets of precision medicine.","PeriodicalId":11140,"journal":{"name":"Diabetes Care","volume":"20 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143672363","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}

The Atlantic Diabetes in Pregnancy (ATLANTIC DIP) network has followed this philosophy. Women now achieve better pregnancy preparation and have lower blood glucose and lower glycated hemoglobin with improved pregnancy outcomes. Screening and follow-up for gestational diabetes mellitus (GDM) is consistent. The trial on early metformin in addition to usual care in the reduction of GDM effects (A Randomized Placebo-Controlled Trial of the Effectiveness of Metformin in Addition to Usual Care in the Reduction of Gestational Diabetes Mellitus Effects [EMERGE]) provides evidence for metformin use in pregnancies complicated by GDM as an alternative to insulin.

PURPOSE To systematically identify guidelines on inpatient hyperglycemia management. DATA SOURCES MEDLINE, Guidelines International Network, and specialty society websites were searched from 1 January 2010 to 14 August 2024. STUDY SELECTION Clinical practice guidelines pertaining to blood glucose management in hospitalized adults were included. DATA EXTRACTION Two authors screened articles and extracted data, and three assessed guideline quality. Recommendations on inpatient monitoring, treatment targets, medications, and care transitions were collected. DATA SYNTHESIS Guidelines from 10 organizations met inclusion criteria, and 5 were assessed to be of high quality per the Appraisal of Guidelines for REsearch & Evaluation II (AGREE II) instrument. All guidelines recommended monitoring blood glucose for patients with diabetes and nine for admission hyperglycemia. Eight guidelines recommended an upper blood glucose target of 180 mg/dL, five with a lower limit of 100 mg/dL and three of 140 mg/dL. Guidelines were in agreement on using capillary blood glucose monitoring, and three guidelines included discussion of continuous monitoring. Hyperglycemia treatment with basal-bolus insulin alone (n = 3) or with correction (n = 5) was most commonly recommended, while sliding scale insulin was advised against (n = 5). Guidance on use of oral diabetes medications was inconsistent. Five guidelines included discussion of transitioning to home medications. Recommendations for hypoglycemia management and diabetes management in older adults were largely limited to outpatient guidance. LIMITATIONS Non-English-language guidelines were excluded. CONCLUSIONS While there is consensus on inpatient blood glucose monitoring and use of basal-bolus insulin, there is disagreement on treatment targets and use of home medications and little guidance on how to transition treatment at discharge.","PeriodicalId":11140,"journal":{"name":"Diabetes Care","volume":"70 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143672350","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 post hoc analysis used pooled data across trials. Baseline characteristics, change from baseline to week 40/42 for efficacy parameters, and gastrointestinal (GI) adverse events (AEs) were described and analyzed by early response in terms of FSG (SURPASS-1 to -4; n = 3,676) or weight (SURPASS-1 to -5; n = 4,121) in the efficacy and safety analysis set, respectively. RESULTS Early responders in FSG (50%) were younger, with higher glycemic parameters and lower weight at baseline. Early responders in weight (31%) had lower glycemic parameters and weight at baseline, and a greater percentage were women and White. Early versus nonearly responders in FSG or weight achieved better HbA1c (−2.6% vs. −2.0% or −2.5% vs. −2.2%, respectively) and weight (−11% vs. −10% or −15% vs. −8%, respectively) responses at week 40/42 and greater improvements in blood pressure and lipids profile.
