Design: Systematic review and meta-analysis of studies reporting on AI prediction models for macrovascular complications in T2DM patients. Setting: The review included studies conducted in various healthcare settings, primarily from LMICs, upper-middle-income countries (UMICs), and high-income countries (HICs). Participants: 46 studies were included, with a total of 184 AI models. Participants were diverse in age, sex, and geographical locations, reflecting a broad range of healthcare settings. Interventions: The intervention analyzed was the application of AI models, including machine learning algorithms, to predict macrovascular complications such as stroke, CVD, and PVD. Primary and Secondary Outcome Measures: The primary outcome was the predictive performance of AI models, measured by the area under the receiver operating characteristic curve (AUROC). Secondary outcomes included subgroup analyses based on predictor types and an assessment of AI model applicability in low-resource settings. Results: Twelve included studies yielded 184 AI models with an overall AUROC of 0.753 (95%CI: 0.74-0.766; I2=99.99%; p&lt;0.001). For 80 models of cardiovascular outcomes, an AUROC of 0.741 (95%CI: 0.721-0.76; I2=99.78%; p&lt;0.001) was obtained. Meanwhile, 25 models of peripheral vascular disease and 38 models of cerebrovascular diseases obtained AUROCs of 0.794 (95%CI: 0.758-0.831; I2=97.23%; p&lt;0.001) and 0.77 (95%CI: 0.743-0.797; I2=99.73%; p&lt;0.001) respectively. Subgroup analysis revealed that models with lab-only predictors were superior to those with mixed or no-lab predictors. This signalled the lack of AI capability for history-taking and physical examination data alone, primarily available in low-resource settings. Conclusions: Artificial intelligence is promising in predicting diabetes complications. Nevertheless, future studies should explore accessible features in low-resource settings and employ external validation to ensure the robustness of the prediction models.","PeriodicalId":501419,"journal":{"name":"medRxiv - Endocrinology","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142183668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A major challenge is inter-individual variability, which limits the effectiveness of population-wide dietary interventions. To develop personalized interventions, it is critical to first predict a person's vulnerability to postprandial glucose excursions, or elevated post-meal glucose relative to a personal baseline, with minimal burden. We examined the feasibility of personalized models to predict future glucose excursions in the daily lives of 69 Chinese adults with type-2 diabetes (M age=61.5; 50% women; 2595 glucose observations). We developed machine learning models, trained on past individual context and meal-based observations, employing low-burden (continuous glucose monitoring) or additional high-burden (manual meal tracking) approaches. Personalized models predicted glucose excursions (F1-score: M=74%; median=78%), with some individuals being more predictable than others. The low burden-models performed better for those with consistent meal patterns and healthier glycemic profiles. Notably, no two individuals shared the same meal and context-based vulnerability predictors. This study is the first to predict individual vulnerability to glucose excursions among a sample of Chinese adults with type-2 diabetes. Findings can help personalize just-in-time-adaptive dietary interventions to unique vulnerability to glucose excursions in daily live, thereby helping improve diabetes management.","PeriodicalId":501419,"journal":{"name":"medRxiv - Endocrinology","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141931404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: We conducted a cross-sectional analysis of medication exposure in adults hospitalized at 16 hospitals in Ontario, Canada between 2015 and 2022. We estimated the proportion with T2DM, obesity, and cardiovascular disease. We identified the frequency of GLP-1RA use, and conducted multivariable logistic regression to identify factors associated with their use. Results: Across 1,278,863 hospitalizations, 396,084 (31%) patients had T2DM and approximately 327,844 (26%) had obesity.

The METS-IR, a novel non-insulin-based tool, is gaining attention for quantifying insulin resistance using multiple metabolic parameters. Despite its potential in predicting diabetes and its precursors, evidence on its specific relationship with diabetes is limited, especially in large-scale population validation and mechanistic exploration.\u0000Objective\u0000This study aims to analyze the association between METS-IR and type 2 diabetes (T2DM) in American adults.\u0000Methods\u0000We conducted a cross-sectional analysis of NHANES data from 2009 to 2018. Participants aged 20 years and above were included, excluding individuals with missing data on BMI, fasting blood glucose (FBG), high-density lipoprotein cholesterol (HDL-C), glycated hemoglobin (HbA1c) and diabetes status. Logistic regression analysis, subgroup analysis, and restricted cubic spline analysis were used to assess the association between METS-IR and T2DM, controlling for potential confounding factors.\u0000Results\u0000After adjusting for age, gender, race, education level, smoking status, drinking habits, depression, physical activity, hypertension, and hyperlipidemia, we found a positive association between METS-IR and the risk of T2DM. Specifically, each unit increase in METS-IR was associated with a 7% increase in the risk of T2DM (OR=1.07, 95% CI: 1.06, 1.08).
