Background: Obesity is one of the most significant risk factors for type 2 diabetes (T2D), but a large number of patients with morbid obesity maintain normal glycemia for a long time. There are no definite easy-to-measure clinical features that distinguish severely obese people who will or will not develop T2D. These features may be useful in clinical practice to predict T2D development in obese patients.Aims: We aimed to identify clinical features (lifestyle factors, obesity history, concomitant diseases) that may be associated with T2D in obese patients.Materials and methods: The study was conducted at single center during 2002 and 2017 and recruited patients with BMI≥30 kg/m2 who attended bariatric surgeon. Patients weight and height were assessed by the doctor, other features were obtained from the questionnaire: overweight and obesity history (age of onset, duration, family history of obesity), lifestyle factors, T2D and concomitant diseases medical history. Patients were divided into 2 groups with regard to the presence of T2D. Data analysis was performed with Statistica 13.3.Results: The study included 170 patients with known T2D and 528 patients without history of T2D and prediabetes. Both groups had similar gender structure, as well as current and peak BMI. There were no significant differences in overweight/obesity duration, obesity family history, lifestyle factors and smoking status of patients. Obese patients without T2D were younger than T2D patients at the time of T2D onset (median age 40 and 45 years respectively). Patients without T2D started to gain weight earlier than those with T2D (median age 17 and 25 years respectively) and reached their peak BMI during 1 year before study entry, while patients with T2D went through maximum weight previously. The frequencies of concomitant diseases didn’t differ between the groups with the exception of hypertension that started later in patients with T2D (median age 51 and 47 years in patients with and without T2D respectively); also patients with T2D had gastroesophageal reflux disease (GERD) and chronic back pain less often than patients without T2D with regard to age.Conclusions: Clinical features that distinguished obese patients with and without T2D were age at the start of overweight/ obesity and concomitant disease profile (hypertension, GERD, chronic back pain) at corresponding age.

The prevalence of type 2 diabetes is escalating rapidly in Asian countries, with the rapid increase likely attributable to a combination of genetic and lifestyle factors. Recent research suggests that common genetic risk variants contribute minimally to the rapidly rising prevalence. Rather, recent changes in dietary patterns and physical activity may be more important. This nested case-control study assessed the association and predictive utility of type 2 diabetes lifestyle risk factors in participants from Malaysia, an understudied Asian population with comparatively high disease prevalence. The study sample comprised 4077 participants from The Malaysian Cohort project and included sub-samples from the three major ancestral groups: Malay (n = 1323), Chinese (n = 1344) and Indian (n = 1410). Association of lifestyle factors with type 2 diabetes was assessed within and across ancestral groups using logistic regression. Predictive utility was quantified and compared between groups using the Area Under the Receiver-Operating Characteristic Curve (AUC). In predictive models including age, gender, waist-to-hip ratio, physical activity, location, family history of diabetes and average sleep duration, the AUC ranged from 0.76 to 0.85 across groups and was significantly higher in Chinese than Malays or Indians, likely reflecting anthropometric differences. This study suggests that obesity, advancing age, a family history of diabetes and living in a rural area are important drivers of the escalating prevalence of type 2 diabetes in Malaysia.

In recent decades, type 2 diabetes is increasingly recorded in young people, adolescents and children. The most significant risk factors for type 2 diabetes in young patients are family history of the disease, overweight and obesity, and the presence of insulin resistance. The main diagnostic criteria for type 2 diabetes mellitus in young patients, in addition to the traditional ones (hyperglycemia and glycosylated hemoglobin), are a high level of C-peptide and insulin resistance in the absence of antibodies to ICA, insulin, GAD. In connection with the projected increase in the incidence of type 2 diabetes at a young age, it is necessary to pay attention to the implementation of preventive measures and timely clinical examination among groups of children and adolescents with the presence of abdominal obesity, burdened with a family history of obesity and type 2 diabetes, in order to prevent or delay the early development of disorders carbohydrate metabolism among this group at an earlier age. Given the predominance of insulin resistance in the pathogenesis of type 2 diabetes in young people, it is necessary to give priority to drugs from the metformin group when prescribing treatment. Thus, the global growth of type 2 diabetes, the tendency to "rejuvenate" diabetes, insufficient information on the prevalence, risk factors and clinical manifestations of the disease at a young age emphasize the urgency of studying this problem.

IntroductionWe sought to investigate the relationship between serum 25-hydroxyvitamin D (25(OH)D) level and the risk of type 2 diabetes mellitus (T2DM) in adults who participated in the Trøndelag Health Study (HUNT), and the possible effect modification by family history and genetic predisposition.Research design and methodsThis prospective study included 3574 diabetes-free adults at baseline who participated in the HUNT2 (1995–1997) and HUNT3 (2006–2008) surveys. Serum 25(OH)D levels were determined at baseline and classified as <50 and ≥50 nmol/L. Family history of diabetes was defined as self-reported diabetes among parents and siblings. A Polygenic Risk Score (PRS) for T2DM based on 166 single-nucleotide polymorphisms was generated. Incident T2DM was defined by self-report and/or non-fasting glucose levels greater than 11 mmol/L and serum glutamic acid decarboxylase antibody level of <0.08 antibody index at the follow-up. Multivariable logistic regression models were applied to calculate adjusted ORs with 95% CIs. Effect modification by family history or PRS was assessed by likelihood ratio test (LRT).ResultsOver 11 years of follow-up, 92 (2.6%) participants developed T2DM. A higher risk of incident T2DM was observed in participants with serum 25(OH)D level of<50 nmol/L compared with those of ≥50 nmol/L (OR 1.72, 95% CI 1.03 to 2.86). Level of 25(OH)D<50 nmol/L was associated with an increased risk of T2DM in adults without family history of diabetes (OR 3.87, 95% CI 1.62 to 9.24) but not in those with a family history (OR 0.72, 95% CI 0.32 to 1.62, p value for LRT=0.003). There was no effect modification by PRS (p value for LRT>0.23).ConclusionSerum 25(OH)D<50 nmol/L was associated with an increased risk of T2DM in Norwegian adults. The inverse association was modified by family history of diabetes but not by genetic predisposition to T2DM.

Abstract Objective MicroRNAs are known to regulate 60% of genes at post translational level. MicroRNAs including Micro RNA-29 family play a vital role in cellular activities and have validate role in numerous metabolic disorders inclusive of diabetes mellitus and its complications. While micro RNA profile changes years before the occurrence of disease. This cross-sectional study was conducted in non-diabetic adults of diabetic and non-diabetic parents to explore the early changes in expression of micro RNA-29 family as it can be served as early biomarker of type 2 diabetes in non-diabetic adults. This study was conducted from January 2019 to January 2021. Micro RNA was extracted from plasma of 50 participants and expression was compared through qPCR. While data was analyzed through SPSS version 21.0. Results 29a and 29b had lower expression in participants with family history of DM compared to those having no family history of DM (P < 0.0001). While micro RNA 29c was found to be significantly higher in participants with positive family history of type 2 diabetes as compared to those without family history of diabetes (P = 0.001).

Objective We aimed to investigate whether patients with polycystic ovary syndrome (PCOS) and a family history (FH) of type 2 diabetes mellitus (T2DM) are at increased risk of endocrinological and metabolic abnormalities, and whether this risk differs between first-degree and second-degree relatives, and between maternal and paternal transmission. Methods A total of 680 patients with PCOS were enrolled in this retrospective, single-center study. Endocrine and glycolipid metabolism parameters were compared. Results The free androgen index (FAI), and levels of fasting blood glucose (FBG), fasting insulin (FINS), homeostatic model assessment-insulin resistance (HOMA-IR), total cholesterol (TC), and low-density lipoprotein cholesterol were significantly higher, whereas sex hormone binding globulin (SHBG) levels were significantly lower in patients with PCOS and a FH of T2DM. In patients with PCOS with a FH of T2DM in first-degree relatives, age and levels of FBG, FINS, and HOMA-IR were significantly higher than those who had a FH of T2DM in second-degree relatives. A maternal history of T2DM was associated with a higher body mass index, FAI, and TG levels, and lower SHBG levels. Conclusions Patients with PCOS and a FH of T2DM have more severe hyperandrogenism and metabolic disorders, especially in those with maternal transmission.

Elevated plasma FFA cause β-cell lipotoxicity and impair insulin secretion in nondiabetic subjects predisposed to type 2 diabetes mellitus [T2DM; i.e., with a strong family history of T2DM (FH+)] but not in nondiabetic subjects without a family history of T2DM. To determine whether lowering plasma FFA with acipimox, an antilipolytic nicotinic acid derivative, may enhance insulin secretion, nine FH+ volunteers were admitted twice and received in random order either acipimox or placebo (double-blind) for 48 h. Plasma glucose/insulin/C-peptide concentrations were measured from 0800 to 2400. On day 3, insulin secretion rates (ISRs) were assessed during a +125 mg/dl hyperglycemic clamp. Acipimox reduced 48-h plasma FFA by 36% ( P < 0.001) and increased the plasma C-peptide relative to the plasma glucose concentration or ΔC-peptide/Δglucose AUC (+177%, P = 0.02), an index of improved β-cell function. Acipimox improved insulin sensitivity (M/I) 26.1 ± 5% ( P < 0.04). First- (+19 ± 6%, P = 0.1) and second-phase (+31 ± 6%, P = 0.05) ISRs during the hyperglycemic clamp also improved. This was particularly evident when examined relative to the prevailing insulin resistance [1/(M/I)], as both first- and second-phase ISR markedly increased by 29 ± 7 ( P < 0.05) and 41 ± 8% ( P = 0.02). There was an inverse correlation between fasting FFA and first-phase ISR ( r2 = 0.31, P < 0.02) and acute (2–4 min) glucose-induced insulin release after acipimox ( r2 =0.52, P < 0.04). In this proof-of-concept study in FH+ individuals predisposed to T2DM, a 48-h reduction of plasma FFA improves day-long meal and glucose-stimulated insulin secretion. These results provide additional evidence for the important role that plasma FFA play regarding insulin secretion in FH+ subjects predisposed to T2DM.
