 Objective. To estimate the incidence of type 2 diabetes (T2D) in Mexican population. Materials and methods. Population based prospective study. At baseline (1990), the population at risk (1939 non-diabetic adults 35-64 years) was evaluated with oral glucose tolerance test. Subsequent similar evaluations were done (1994, 1998, 2008). American Diabetes Association diagnostic criteria were applied. Re­sults. The period of observation was 27842 person-years, the cumulative incidence of T2D was 14.4 and 13.7 per 1000 person-years for men and women, respectively. Incidence was 15.8, 15.7 and 12.7 per 1 000 person-years for the second (1994), third (1998) and fourth (2008) follow-up phases, respectively. The mean age at diagnosis was 44 years for prevalent cases and 56 years for incident cases. Conclu­sions. This is the first estimate of long-term incidence of T2D in Mexican population. The incidence is among the highest reported worldwide. It remained with few changes throughout the study period.

AbstractAimsSerum uromodulin has recently emerged as promising biomarker for kidney function and was suggested to be associated with type 2 diabetes (T2D) in patients with coronary heart disease. Here, we analyzed the association of serum uromodulin with T2D in the population-based KORA F4/FF4 study.MethodsIn 1119 participants of the KORA F4 study aged 62 to 81 years, serum uromodulin was measured, and the association of serum uromodulin with T2D was assessed using logistic and linear regression models stratified for sex. After a mean follow-up time of 6.5 years, 635 participants where re-evaluated. Glucose tolerance status was determined by oral glucose tolerance test at baseline and at the follow-up examination except in cases of known T2D.ResultsSerum uromodulin was inversely associated with T2D in the crude analysis and after adjustment for age and body mass index in men (P < 0.001) and in women (P < 0.05). After further adjustment for estimated glomerular filtration rate, serum uromodulin was significantly inversely associated with T2D in men (P < 0.001) but not in women. Serum uromodulin was not associated with prediabetes after multivariate adjustment and did not predict T2D in men or in women after the follow-up time of 6.5 ± 0.3 years.ConclusionsIn participants of the KORA F4 study, serum uromodulin is independently associated with T2D in men but is not a predictor of future development of T2D.

Abstract We previously reported a nonrandomized case control study that showed significant improvements in BMI, HbA1c and HDL levels in 30 diabetic veterans who underwent sleeve gastrectomy (SG) through 2 yrs, compared to 23 controls receiving medical management. BMI decreased from 46 to 34 over two yrs and HbA1c from 7.3 to 5.9% in the SG group. We now report the 8 yr follow up. Since then, bariatric surgery has increasingly become an option for the management of not only obesity but also type 2 diabetes. More data is needed on long term outcomes of bariatric surgery compared to medical care. Our cohort is mainly men with more comorbidities and higher average age than typically included in other cohorts that usually include more women. Objectives: The main objective was to compare long term changes in weight, HbA1C, lipids and creatinine in SG group vs. controls. Secondary objectives analyzed were cardiovascular (CV) and mental health outcomes in SG cases and controls. Methods: Charts for diabetic veterans 18 to 80 yrs were reviewed over an 8 yr period. Data was analyzed using Friedman Test, Wilcoxon Signed Rank test with 2-tailed significance level set at p&lt;05. Results: 23 cases and 22 controls were included in the 8-year data analysis. Mean age was 56 and 96% were male. The mean BMI and HbA1C at baseline were 45 and 7.3 in SG group with 41% on insulin and 42 and 8.4 for controls with 59% on insulin. A Friedman test found significant differences in mean changes in weight for BMI, HbA1C and HDL between SG cases and controls over the 8 yrs. (chi-square = 327.48; df = 4; p&lt;0.000001). Follow up pairwise comparisons used a Wilcoxon test. HDL was higher in the SG group (p&lt;.05) in each yr. Mean change in weight and BMI was significantly better for the SG group in the first 6 yrs after SG (p&lt; .01). Nonetheless, the mean weight and BMI of SG group remained below their mean baseline weight and BMI for the full 8 year-period. The mean change in HbA1C was significantly better for the SG group in only the first 2 yrs (p&lt;0.05). LDL change was significantly worse in SG group but not in all years. There were no significant differences in creatinine. Patients who had SG had fewer CV events 8 yrs after SG (baseline OR: 4.17, yr 8 OR:0.77). However, they also had more mental health diagnoses (yr 8 OR: 1.61). Conclusion:The weight loss in the SG group, as compared to controls, lessened over time remaining statistically significant until yr 6. However, the SG group mean BMI and weight remained below baseline at 8 years. HbA1C change remained significantly better in the SG group compared to controls only during the first 2 yrs. Follow up diabetes management in SG group was less consistent than controls. HDL remained significantly higher among the SG group which may be explain the lower CV events in this group. Awareness of more mental health diagnoses among bariatric surgery patients may lead to improved management and better adherence to a healthy lifestyle.

Abstract Aims Depression in type 2 diabetes may heavily affect the course of the disease. In this study, we investigated, among new cases with type 2 diabetes, the incidence and clinical predictors of depression and determined the extent to which depression constitutes a risk factor for acute and long-term diabetes complications and mortality. Methods In this population-based retrospective cohort study, incident cases of type 2 diabetes without a prior history of depression were identified from the administrative databases of the Emilia-Romagna Region, Italy, between 2008 and 2017 and followed up until 2020. Logistic regression models were used to identify the predictors of depression. Cox regression models were used to estimate the risk of acute complications over three years, and the risk of long-term complications and mortality over ten years. Results Incident cases with type 2 diabetes were 30,815, of whom 5146 (16.7%) developed depression. The predictors of depression onset were as follows: female sex, age > 65 years, living in rural areas and comorbid diseases. Depression in type 2 diabetes was associated with a 2.3-fold risk of developing acute complications, 1.6-fold risk of developing long-term complications and 2.8-fold mortality risk. Conclusions Our findings highlight that depression is associated with an increased risk for complications in type 2 diabetes and mortality and should not be neglected. Therefore, it is important to promote screening activities and introduce targeted and personalized treatment for depression in order to reduce the risk of poor short- and long-term outcomes of diabetes.

AbstractBackground:Endocrine evaluation and long-term follow-up of seven (six male) patients with Williams-Beuren syndrome (WBS) are given.Method:Data were obtained from patients’ medical records. All patients underwent hormonal analyses and four of them underwent oral glucose tolerance test (OGTT).Results:They all had mild hypercalcemia. Three of them had overt hypothyroidism while subclinical hypothyroidism was detected in three patients. Four patients had thyroid hypoplasia and one had thyroid agenesis. Growth hormone deficiency (GHD) was determined in one patient. Impaired glucose tolerance (IGT) was found in three adolescents. All adolescents had early-onset puberty. The follow-up duration was 5.7±2.1 years. The mean growth velocity (GV) was 12.9±7.2 cm and 7.6±2 cm at the end of the first and second years of therapy, respectively. All patients had neurodevelopment retardation and were continuing to special education.Conclusions:Thyroid hypoplasia is common and agenesis can be seen in patients with WBS; therefore, thyroid hormones should be measured in the newborn period and annually. GHD should be kept in mind in patients with decreased GV. IGT might be detected in patients with WBS even in adolescence.

25 Hydroxyvitamin D

Aim. To examine whether the baseline 25-hydroxyvitamin D [25(OH)D] level was predictive of the onset of prediabetes or type 2 diabetes (T2DM) in the Chinese population. Methods. This was a 4-year follow-up study that was conducted in the Chengdu region of China as part of the China National Diabetes and Metabolic Disorders Study. The study included 490 participants that were free of prediabetes and type 2 diabetes mellitus (T2DM) at baseline and had complete data by follow-up examinations. Glucose, insulin, and 25(OH)D levels were measured at baseline and at 4 years later. Prediabetes and T2DM were defined by results obtained from an oral glucose tolerance test. Results. Over a 4-year follow-up, 95 (48.5‰) developed prediabetes and 31 (15.8‰) individuals developed diabetes. Low 25(OH)D status was significantly associated with the risk of developing prediabetes [OR 3.01 (95% CI: 1.50–6.06), P=0.002] and T2DM [OR 5.61 (95% CI: 1.73–18.27), P=0.004] after adjustment for multiple potential confounders. In a multiple linear regression analysis, low baseline levels of 25(OH)D were an independent predictor of increased insulin resistance over a 4-year period (P<0.05). Conclusions. The current prospective study suggests that low 25(OH)D levels might have contributed to the incidence of prediabetes or T2DM in Chinese individuals. This trial is registered with TR-CCH-ChiCTR-OCS-09000361.

Abstract/SummaryBackground and aims:Understanding the aetiology, clinical presentation and prognosis of type 2 diabetes (T2D) and optimizing its treatment might be facilitated by biomarkers that help predict a person’s susceptibility to the risk factors that cause diabetes or its complications, or response to treatment. The IMI DIRECT (Diabetes Research on Patient Stratification) Study is a European Union (EU) Innovative Medicines Initiative (IMI) project that seeks to test these hypotheses in two recently established epidemiological cohorts. Here, we describe the characteristics of these cohorts at baseline and at the first main follow-up examination (18-months).Materials and methods:From a sampling-frame of 24,682 European-ancestry adults in whom detailed health information was available, participants at varying risk of glycaemic deterioration were identified using a risk prediction algorithm and enrolled into a prospective cohort study (n=2127) undertaken at four study centres across Europe (Cohort 1: prediabetes). We also recruited people from clinical registries with recently diagnosed T2D (n=789) into a second cohort study (Cohort 2: diabetes). The two cohorts were studied in parallel with matched protocols. Endogenous insulin secretion and insulin sensitivity were modelled from frequently sampled 75g oral glucose tolerance (OGTT) in Cohort 1 and with mixed-meal tolerance tests (MMTT) in Cohort 2. Additional metabolic biochemistry was determined using blood samples taken when fasted and during the tolerance tests. Body composition was assessed using MRI and lifestyle measures through self-report and objective methods.Results:Using ADA-2011 glycaemic categories, 33% (n=693) of Cohort 1 (prediabetes) had normal glucose regulation (NGR), and 67% (n=1419) had impaired glucose regulation (IGR). 76% of the cohort was male, age=62(6.2) years; BMI=27.9(4.0) kg/m2; fasting glucose=5.7(0.6) mmol/l; 2-hr glucose=5.9(1.6) mmol/l [mean(SD)]. At follow-up, 18.6(1.4) months after baseline, fasting glucose=5.8(0.6) mmol/l; 2-hr OGTT glucose=6.1(1.7) mmol/l [mean(SD)]. In Cohort 2 (diabetes): 65% (n=508) were lifestyle treated (LS) and 35% (n=271) were lifestyle + metformin treated (LS+MET). 58% of the cohort was male, age=62(8.1) years; BMI=30.5(5.0) kg/m2; fasting glucose=7.2(1.4)mmol/l; 2-hr glucose=8.6(2.8) mmol/l [mean(SD)]. At follow-up, 18.2(0.6) months after baseline, fasting glucose=7.8(1.8) mmol/l; 2-hr MMTT glucose=9.5(3.3) mmol/l [mean(SD)].Conclusion:The epidemiological IMI DIRECT cohorts are the most intensely characterised prospective studies of glycaemic deterioration to date. Data from these cohorts help illustrate the heterogeneous characteristics of people at risk of or with T2D, highlighting the rationale for biomarker stratification of the disease - the primary objective of the IMI DIRECT consortium.Abbreviations:ASATAbdominal subcutaneous adipose tissueDIRECTDiabetes Research on Patient StratificationEUEuropean UnionMMTTMixed-meal tolerance testMRIMagnetic resonance imaginghpfVMHigh-pass filtered vector magnitudeIAATIntra-abdominal adipose tissueIGRImpaired glucose regulationIMIInnovative Medicines InitiativeMEmultiechoNGRNormal glucose regulationOGTTOral glucose tolerance testPAPhysical activityTAATTotal abdominal adipose tissueT2DType 2 Diabetes
