Introduction Schizophrenia patients are at greater risk of obesity, diabetes mellitus (DM), lipid abnormalities and cardiovascular disorders. The metabolic complications in patients are associated with several risk factors: family history of DM, lifestyle, smoking, dietary habits, physical inactivity, but also with antipsychotic medication. In literature, most publications have been focused on the effects of the second generation antipsychotics (SGA) on glucose metabolism. However, less attention has been paid to abnormality in glucoregulation, patients with schizophrenia treated with the first generation antipsychotics (FGA). Objective The present study evaluated glucose metabolism in normal weight schizophrenia patients treated with FGA. METHOD The cross-sectional study included 18 patients (FGA treated) and 20 healthy controls with neither group differences in sex distribution, age, nor in BMI. Inclusion criteria were normal BMI (20-25 kg/m2). The glucose levels, insulin levels and growth hormone levels during oral glucose tolerance test (OGTT) were measured. Results Fasting glucose and insulin levels did not differ significantly between groups. Groups differed in OGTT glucose and insulin peak and area under curve (AUC), level of significance p<0.05 (patients vs. controls: glucose peak 8.3?0.4 vs.6.9?0.5 mmol/l, glucose AUC 758?28 vs. 640?36 mU/l/120 min; insulin peak in patients 92.7?15.6 mU/l; insulin AUC 6060?1016 mU/l/120 min, insulin peak in controls 47.9?6.5 mU/l; insulin AUC 2597?256 mU/l/120 min). Conclusion Patients with schizophrenia, although with normal body mass index, are at high risk of abnormal glucose regulation. Not only SGA increase the risk of impaired glucoregulation and metabolic syndrome, but this may also be due to FGA or schizophrenia per se. .

Sagittal Abdominal Diameter

The objective was to compare associations between sagittal abdominal diameter (SAD), waist circumference, and BMI to the oral glucose tolerance test (OGTT), along with fasting glucose, HbA1c, and HOMA-IR, in a nationally representative sample of 3582 US adults. The study also analyzed the effect of multiple covariates on the anthropometric and glucose metabolism associations. A cross-sectional design was used. SAD was assessed using an abdominal caliper. All other data were collected following strict NHANES protocols. The OGTT was the primary variable used to index glucose metabolism. Fasting glucose, HbA1c, and HOMA-IR were also evaluated. Results showed that mean ± SE values were as follows: SAD: 22.3 ± 0.1 cm, waist circumference: 98.0 ± 0.4 cm, BMI: 28.6 ± 0.2 kg/m2, OGTT: 113.9 ± 1.0 mg/dL, fasting glucose: 99.6 ± 0.3 mg/dL, HbA1c: 5.4 ± 0.01%, and HOMA-IR: 3.2 ± 0.1. Compared to waist circumference and BMI, SAD consistently emerged as the best predictor of glucose metabolism, before and after adjusting for the covariates, and with the sample stratified by gender, race, or age. SAD was not a better predictor of OGTT among normal-weight adults or non-Hispanic Black adults. Due to the ease of taking SAD measurements, we recommend that healthcare providers use this simple method to more precisely predict diabetes risk, especially among overweight and obese adults.

ObjectiveTo explore inflammatory mediators in morbidly obese (MO) subjects with various categories of glucose tolerance and to study the changes in these mediators after an oral glucose load.DesignCross-sectional and experimental study.MethodsA total of 144 MO subjects were classified into three categories: normal glucose tolerance (NGT); pre-diabetes; and new onset diabetes mellitus (NODM) were included, as were 27 normal weight normoglycemic controls. Serum osteoprotegerin (OPG), visfatin, leptin, adiponectin, interleukin-1 receptor antagonist (IL-1Ra), and C-reactive protein (CRP) were analyzed during an oral glucose tolerance test (OGTT).ResultsFasting levels of leptin and IL-1Ra were consistently higher in obese persons (P<0.001 and P<0.05). MO subjects with NGT had higher CRP levels (P<0.001) and lower adiponectin levels (P<0.05) compared to controls. Yet when compared with MO subjects with NODM, those with NGT had lower CRP levels and higher adiponectin levels (both P<0.05). Baseline OPG and visfatin levels did not differ between the groups (P=0.326 and P=0.198). During OGTT, OPG levels decreased (P<0.001) and visfatin levels increased transiently (P=0.018). The response in OPG and visfatin did not differ between the groups (P=0.690 and P=0.170). There were minor changes in adiponectin and leptin levels.ConclusionsMorbid obesity and glucose intolerance were associated with lower adiponectin levels and higher CRP levels, thus supporting a relationship between obesity, glucose homeostasis, and inflammation. Oral glucose suppressed OPG levels and transiently enhanced visfatin levels independent of obesity and glucose tolerance status, indicating that glucose may be involved in the acute regulation of these proteins.

Objective: Study the association of dietary habits and other indicators of lifestyle with dysglycemia in Saudi adults. Methods: In a cross-sectional design, data were obtained from 1403 Saudi adults (⩾20 years), not previously diagnosed with diabetes. Demographics, lifestyle variables and dietary habits were obtained using a predesigned questionnaire. Fasting plasma glucose, glycated hemoglobin and 1-hour oral glucose tolerance test were used to identify dysglycemia. Regression analysis was performed to determine the associations of dietary factors and other indicators of lifestyle with dysglycemia. Results: A total 1075 adults (596 men, and 479 women) had normoglycemia, and 328 (195 men, and 133 women) had dysglycemia. Following adjustment for age, BMI and waist circumference, in men the weekly intake of 5 portions or more of red meat and Turkish coffee were associated with decreased odds of having dysglycemia odds ratio (OR) 0.444 (95% CI: 0.223, 0.881; P = .02) and 0.387 (95% CI: 0.202, 0.74; P = .004), respectively. In women, the intake of fresh juice 1 to 4 portions per week and 5 portions or more were associated with OR 0.603 (95% CI: 0.369, 0.985; P = .043) and OR 0.511 (95% CI: 0.279, 0.935; P = .029) decreased odds of having dysglycemia, respectively compared with women who did not drink fresh juice. The intake of 5 times or more per week of hibiscus drink was associated with increased odds of having dysglycemia, OR 5.551 (95% CI: 1.576, 19.55, P = .008) compared with women not using such a drink. Other lifestyle factors were not associated with dysglycemia. Conclusion: Dietary practices by studied Saudis have some impact on risk of dysglycemia, with obvious sex differences.

Data concerning metabolic consequences in women with polycystic ovary syndrome (PCOS) are delivered mainly by cross-sectional studies. In this research, we re-examined 31 Caucasian PCOS women after a median period of 120.9 months to evaluate the changes in metabolic syndrome components. Clinical examination, oral glucose tolerance test with estimations of glucose and insulin, lipids, sex hormone-binding globulin (SHBG) and sex hormones assessments were performed on two occasions. Additionally, the euglycaemic hyperinsulinaemic clamp technique was used at the baseline to assess insulin sensitivity (M-clamp value). In the end, the median age of participants was 35. We observed an increase in glucose concentrations, a decrease in insulin concentrations and no changes in insulin resistance markers. Final mean glucose, mean insulin, Matsuda index and body mass index (BMI) were correlated with baseline M-clamp value and SHBG (p < 0.01). During the follow-up, no one in the sample developed diabetes. The annualised incidence rate for conversion from normoglycaemia to prediabetes totalled 4.5%. Baseline BMI, free androgen index, fasting glucose and M-clamp value were identified as prediabetes predictors in young PCOS women (respectively, OR = 1.17, OR = 1.42, OR = 1.2, OR = 0.73, p < 0.05). Prediabetes appeared in 76.47% of the women with a final BMI of ≥ 25 kg/m2 and in 7.14% of the normal-weight women (p = 0.0001). In conclusion, we report a high rate of adverse change in glucose metabolism in overweight and obese participants, a deterioration in β-cell function and strong correlations between metabolic parameters assessed in the third and the fourth decade in PCOS women, emphasising the role of early intervention to prevent cardiometabolic diseases.

AbstractBackground:Adipokines have been implicated in obesity, insulin resistance and sleep regulation. However, the role of chemerin and progranulin, two recently described adipokines, in the context of sleep remains unclear. The aim of this study was to compare nocturnal serum chemerin and progranulin levels between overweight/obese and normal-weight adolescents and to assess variations by sex, across different sleep stages and in relation to glucose metabolism.Methods:The study sample included 34 overweight/obese and 32 normal-weight adolescents from secondary schools and the Leipzig Research Center for Civilization Diseases (LIFE) Child study cohort. We obtained longitudinal serum adipokine levels during in-laboratory polysomnography followed by an oral glucose tolerance test.Results:Overweight/obese adolescents had significantly higher mean nocturnal serum chemerin area under the curve (AUC) levels (348.2±133.3 vs. 241.7±67.7 vs. ng/mL×h, p<0.001) compared to normal-weight controls. In detail, higher chemerin AUC levels in obese/overweight subjects were exclusively due to increased levels in females. No overall difference for serum progranulin AUC was found between the groups. However, when assessing sex-specific levels, serum progranulin AUC levels were ~30% higher in overweight/obese males compared to overweight/obese females. Of note, nocturnal serum chemerin and progranulin AUC did not exhibit a correlation with markers of glucose metabolism or sleep stages.Conclusions:Collectively, we report a sexual dimorphism in nocturnal progranulin and chemerin levels, which may help explain underlying differences in energy balance and body composition between males and females in the context of obesity.

Obesity And Diabetes

Introduction Bisphenol A and several of the most commonly used phthalates have been associated with adverse metabolic health effects such as obesity and diabetes. Therefore, we analyzed these man-made chemicals in first morning urine samples from 107 healthy normal-weight Danish children and adolescents. Method This was a cross-sectional study. Participants were recruited as part of the Copenhagen Puberty Study. The subjects were evaluated by an oral glucose tolerance test (OGTT), a dual-energy X-ray absorptiometry (DXA) scan, direct oxygen uptake measurement during cycle ergometry and fasting blood samples. First morning urine was collected and phthalate metabolites and BPA were measured by liquid chromatography-tandem mass spectrometry (LC–MS/MS) with prior enzymatic deconjugation. Individual chemical concentrations were divided into tertiles and analyzed in relation to biological outcome. Results Children in the lowest tertile of urinary BPA had significantly higher peak insulin levels during OGTT (P = 0.01), lower insulin sensitivity index (P < 0.01), higher leptin (P = 0.03), triglyceride (P < 0.01) and total cholesterol levels (P = 0.04), lower aerobic fitness (P = 0.02) and a tendency toward higher fat mass index (P = 0.1) compared with children in the highest tertile for uBPA. No significant differences in anthropometrics, body composition or glucose metabolism were associated with any of the phthalate metabolites measured. Conclusion This pilot study on healthy normal-weight children suggests an inverse association between BPA and insulin resistance. Our findings contrast other cross-sectional studies showing a positive association for BPA, which may be due to confounding or reverse causation because diet is an important source of both BPA exposure and obesity.

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.
