In addition to the caloric and macronutrient composition of meals, timing of energy consumption may be important for optimal glucose metabolism. Our goal was to examine whether the habitual timing of energy intake was associated with insulin sensitivity in healthy volunteers. Volunteers without diabetes aged 21–50 years completed a 3-day food diary and underwent an oral glucose tolerance test to estimate insulin sensitivity (n = 44). From the food diary, we calculated the proportions of the total energy and macronutrients consumed in the morning and evening, and the clock time at which 25%, 50% and 75% of total energy was consumed. A greater proportion of energy intake in the morning was significantly associated with higher insulin sensitivity estimated by Matsuda Index (B = 2.8 per 10%; 95%CI: 0.3, 5.2). The time at which 25% of energy was consumed was associated with insulin sensitivity estimated by Matsuda Index (B = −1.6 per hour; 95%CI: −3.0, −0.3) and QUICKI (B = −1.4 per hour, 95%CI: −2.8, −0.1). The timing of carbohydrate consumption demonstrated similar associations. Greater energy intake earlier in the day was associated with higher insulin sensitivity in individuals without diabetes.

Background: Antithrombin 3 (AT3) is a physiological inhibitor of thrombin, and serum AT3 activity was found to be decreased at the status of type 2 diabetes (T2D). T2D was presented with an increased risk of thrombotic complications at the background of impaired insulin sensitivity. The aim of this study was to investigate the relationship between insulin sensitivity indices and serum AT3 activity in patients with T2D. Methods: We conducted a cross-sectional study in patients with T2D who consented to participate in the study at the Endocrinology Department of Affiliated 2 Hospital of Nantong University from January 2015 to June 2018. All patients received serum AT3 activity test and 75-g oral glucose tolerance test (OGTT). Basal and systemic insulin sensitivity were assessed by homeostasis model assessment of insulin resistance (HOMA-IR) and Matsuda index (ISIMatsuda), respectively, from the OGTT. And other relevant clinical data were also collected. Results: Total 1612 patients with T2D were enrolled in the study, with a mean age of 58.67±13.09 years and a median diabetes duration of 6 years (interquartile range, 1–10 years). Across ascending quartiles of serum AT3, HOMA-IR progressively decreased, while ISIMatsuda progressively increased (all p for trend <0.001). Moreover, serum AT3 was negatively correlated with HOMA-IR (r= –0.189, p<0.001) and positively correlated with ISIMatsuda (r=0.221, p<0.001). After adjusting for other metabolic risk factors, hemostatic parameters and glucose-lowering therapies by multivariate liner regression analysis, HOMA-IR (β= −0.185, t= −5.960, p<0.001) and ISIMatsuda (β= 0.197, t=6.632, p<0.001) remained independently associated with the serum AT3 activity in patients with T2D, respectively. Conclusions: Reduced basal and systemic insulin sensitivity are associated with decreased serum AT3 activity in patients with T2D.

Abstract Context Slight elevations in plasma glucose (PG) manifest in advance of diabetes onset, but abnormalities in immunoreactive insulin (IRI), proinsulin (Pro), and adiponectin dynamics during this stage remain poorly understood. Objective The objective of this work is to investigate whether IRI and Pro dynamics become abnormal as glucose tolerance deteriorates from within the normal range toward impaired glucose tolerance (IGT), as well as the relationship between PG, and these dynamics and serum adiponectin levels. Design A cross-sectional study was designed. Setting This study took place at Jichi Medical University in Japan. Participants and Measurements PG, IRI, and Pro levels were determined in 1311 young Japanese individuals (age &lt; 40 years) with normal or IGT before and at 30, 60, and 120 minutes during a 75-g oral glucose tolerance test. Participants were assigned to 4 groups according to glucose tolerance, and then background factors, adiponectin levels, insulin sensitivity (SI), and insulin secretion (β) indexes were determined. Results PG levels as well as IRI and Pro levels 60 and 120 minutes after glucose-loading increased incrementally with deteriorating glucose tolerance. All measures of β and the SI measure index of insulin sensitivity (ISI)-Matsuda decreased incrementally. Serum adiponectin levels were not significantly different among the glucose tolerance groups, but were independently and negatively correlated with fasting glucose. Conclusions Early β decreased and postloading Pro levels became excessive in a progressive manner as glucose tolerance deteriorated from within the normal range toward IGT.

Abstract Background: Serum antithrombin 3 (AT3) is a physiological inhibitor of thrombin, and AT3 activity was found to be decreased at the status of type 2 diabetes (T2D). T2D was presented with an increased risk of thrombotic complications at the background of impaired insulin sensitivity. The aim of this study was to investigate the relationship between insulin sensitivity and serum AT3 activity in patients with T2D. Methods: We recruited 1612 patients with T2D for this cross-sectional study from the Second Affiliated Hospital of Nantong University. All patients performed 75-g oral glucose tolerance test (OGTT), and basal and systemic insulin sensitivity were assessed by homeostasis model assessment of insulin resistance (HOMA-IR) and Matsuda index (ISI Matsuda ), respectively. Serum AT3, one of the hemostatic parameters, and the relevant clinical data were collected, as well as other laboratory indicators. Results: It is showed that HOMA-IR decreased, while ISI Matsuda notably increased, across ascending quartiles of serum AT3. Moreover, serum AT3 were was negatively correlated with (r = –0.189, p < 0.001) and positively correlated with ISI Matsuda (r = 0.221, p < 0.001). After adjusted for metabolic risk factors, hemostatic parameters and glucose-lowering therapies by multivariate liner regression analysis, HOMA-IR (β = −0.179, t = −5.823, p < 0.001) and ISI Matsuda (β = 0.191, t = 6.395, p < 0.001) was remained independently associated with the serum AT3 activity patients with T2D, respectively. Conclusions: Reduced basal and systemic insulin sensitivity are associated with decreased AT3 activity in patients with T2D.

To assess the correlation between main parameters of glycemic control and cardiovascular risk scores in non-diabetic persons. Risk scores were calculated by using the University of Edinburgh Risk Calculator. Risk scores are used to estimate the probability of cardiovascular disease in individuals who have not already developed major atherosclerotic disease. We correlated the results of these scores with the parameters that describes the glycaemic profile: preprandial glicaemia, HbA1c and 1 hour and 2 h post-prandial glycaemia, determined during Oral Glucose Tolerance Test (OGTT).Both fasting glycaemia and HbA1c significantly correlated with cardiovascular risk scores calculated for a period of 10 years. The recorded post-prandial glycaemic values at 1h and 2h after glucose loading didn�t significantly correlate with calculated scores, in the study group. The observed correlations underline the importance of glycaemia in the pathogenesis of cardiovascular diseases.

This cross-sectional study investigated the association of miR-1299, -126-3p and -30e-3p with and their diagnostic capability for dysglycaemia in 1273 (men, n = 345) South Africans, aged >20 years. Glycaemic status was assessed by oral glucose tolerance test (OGTT). Whole blood microRNA (miRNA) expressions were assessed using TaqMan-based reverse transcription quantitative-PCR (RT-qPCR). Receiver operating characteristic (ROC) curves assessed the ability of each miRNA to discriminate dysglycaemia, while multivariable logistic regression analyses linked expression with dysglycaemia. In all, 207 (16.2%) and 94 (7.4%) participants had prediabetes and type 2 diabetes mellitus (T2DM), respectively. All three miRNAs were significantly highly expressed in individuals with prediabetes compared to normotolerant patients, p < 0.001. miR-30e-3p and miR-126-3p were also significantly more expressed in T2DM versus normotolerant patients, p < 0.001. In multivariable logistic regressions, the three miRNAs were consistently and continuously associated with prediabetes, while only miR-126-3p was associated with T2DM. The ROC analysis indicated all three miRNAs had a significant overall predictive ability to diagnose prediabetes, diabetes and the combination of both (dysglycaemia), with the area under the receiver operating characteristic curve (AUC) being significantly higher for miR-126-3p in prediabetes. For prediabetes diagnosis, miR-126-3p (AUC = 0.760) outperformed HbA1c (AUC = 0.695), p = 0.042. These results suggest that miR-1299, -126-3p and -30e-3p are associated with prediabetes, and measuring miR-126-3p could potentially contribute to diabetes risk screening strategies.

Gestational Diabetes Mellitus (GDM) is an important public health problem. Prevalence has shown an increasing trend and varies based on diagnostic criteria used and the ethnic group studied. It is more common in Asia. Presently, there is no international consensus on the screening and diagnostic criteria for GDM. The Diabetes in Pregnancy Study Group of India (DIPSI) guidelines recommend the non-fasting 75g oral glucose tolerance test (OGTT) as a single-step screening and diagnostic test for GDM, is simple, easy and more feasible. The objective of this study was to compare whether the DIPSI criteria is equally sensitive to WHO 2018 criteria. This was a hospital based cross-sectional study done at Nepal Medical College Teaching Hospital, Kathmandu. Among 425 cases, 25 (5.88%) were diagnosed GDM, 6 (1.41%) were diagnosed only by DIPSI, 5 (1.18) only by WHO 2018 and 14 (3.29%) by both methods. The study showed that the sensitivity of DIPSI was 73.68% and specificity was 98.52%. The agreement between the DIPSI and WHO 2018 criteria ranged from 60% to 80% (Kappa value = 0.68). This study proves that DIPSI criteria is comparable to WHO 2018 criteria and can be adopted in our institution for the diagnosis of GDM as it is more feasible, easy and less expensive.

Myocardial Steatosis

Background: Myocardial steatosis, an independent predictor of diastolic dysfunction, is frequently present in type 2 diabetes mellitus. High free fatty acid flux, hyperglycemia, and hyperinsulinemia may play a role in myocardial steatosis. There are no prior studies examining the relationship between insulin sensitivity (antilipolytic and glucose disposal actions of insulin) and cardiac steatosis. Objective: Using a cross-sectional study design of individuals with and without metabolic syndrome (MetSyn), we examined the relationships between cardiac steatosis and the sensitivity of the antilipolytic and glucose disposal actions of insulin. Methods: Pericardial fat (PF) volume, intramyocardial and hepatic fat (MF and HF) content, visceral fat (VF) and sc fat content were assessed by magnetic resonance imaging in 77 subjects (49 without MetSyn and 28 with MetSyn). In a subset of the larger cohort (n = 52), peripheral insulin sensitivity index (SI) and adipocyte insulin sensitivity (Adipo-SI) were determined from an insulin-modified frequently sampled iv glucose tolerance test. The Quantitative Insulin Sensitivity Check Index was used as a surrogate for hepatic insulin sensitivity. Results: Individuals with the MetSyn had significantly higher body mass index, total body fat, and MF, PF, HF, and VF content. HF and VF, but not MF, were negatively correlated with the Quantitative Insulin Sensitivity Check Index, Adipo-SI, and SI. Stepwise regression revealed that waist circumference and serum triglyceride levels independently predicted MF and PF, respectively. Adipo-SI and serum triglyceride levels independently predict HF. Conclusion: Myocardial steatosis is unrelated to hepatic, adipocyte, or peripheral insulin sensitivity. Although it is frequently observed in insulin-resistant subjects, further studies are necessary to identify and delineate pathogenic mechanisms that differentially affect cardiac and hepatic steatosis.

The Relationship

Examining the relationship between glucose intolerance and dietary intake in genetically similar populations with different dietary patterns and rates of type 2 diabetes may provide important insights into the role of diet in the pathogenesis of this disease. The objective of the present study was to assess the relationship between dietary variables and dysglycaemia/type 2 diabetes among three populations of African origin. The study design consists of a cross-sectional study of men and women of African descent aged 24–74 years from Cameroon (n 1790), Jamaica (n 857) and Manchester, UK (n 258) who were not known to have diabetes. Each participant had anthropometric measurements and underwent a 2 h 75 g oral glucose tolerance test. Habitual dietary intake was estimated with quantitative FFQ, developed specifically for each country. The age-adjusted prevalence of undiagnosed type 2 diabetes in Cameroon was low (1·1 %), but it was higher in Jamaica (11·6 %) and the UK (12·6 %). Adjusted generalised linear and latent mixed models used to obtain OR indicated that each 1·0 % increment in energy from protein, total fat and saturated fats significantly increased the odds of type 2 diabetes by 9 (95 % CI 1·02, 1·16) %, 5 (95 % CI, 1·01, 1·08) % and 16 (95 % CI 1·08, 1·25) %, respectively. A 1 % increase in energy from carbohydrates and a 0·1 unit increment in the PUFA:SFA ratio were associated with significantly reduced odds of type 2 diabetes. The results show independent effects of dietary factors on hyperglycaemia in African origin populations. Whether modifying intake of specific macronutrients helps diabetes prevention needs testing in randomised trials.

Abstract Background: Childhood motor skills are important not only for the physical and mental health of children, but also for the prevention of future lifestyle diseases. This study aimed to investigate how motor skills among first-grade children in Japan are associated with dietary and lifestyle habits, after adjustment for various confounding factors.Methods: First-grade children (aged 6-7 years) attending three public elementary schools in Tokyo, Japan (n=884), participated in this cross-sectional study. Homeroom teachers distributed self-administered questionnaires to parents and children. Questionnaires focused on lifestyle habits and required completion of a 1-day dietary record. Motor skills were measured by the New Physical Fitness Test (NPFT). Physique was calculated using Rohrer’s index formula: weight (kg) / height (cm) 3 × 107. Multiple regression analysis was used to investigate the association between NPFT score and determinant factors. We also examined the association between NPFT score and the amount of energy derived from a healthy diet versus snacks.Results: NPFT scores were significantly and positively correlated with involvement in exercise lessons (boys, β = 0.131, P = 0.006; girls, β = 0.121P = 0.012), total energy intake (boys, β = 0.096, P = 0.041; girls, β = 0.145, P = 0.003), and outside playtime in boys (β = 0.135), and negatively correlated with Rohrer’s index in girls (β = -0.097, P = 0.047). Moreover, the amount of energy derived from a healthy diet showed positive correlations with NPFT score (boys, β = 0.120, P = 0.011; girls, β = 0.137, P = 0.005).Conclusions: Children’s motor skills were associated with the Rohrer’s index, involvement in sports lessons, outside playtime, and total energy intake, particularly that derived from a healthy diet. These results suggest that a well-balanced diet including grains, vegetables, fish and meat, fruits, and milk, is important for improving children’s motor skills.
