Resistant starch ameliorated insulin resistant in patients of type 2 diabetes with obesity: a systematic review and meta-analysis

Abstract Background Resistant starch (RS) is a starch that can be fermented by the microbial flora within gut lumen. Insulin resistance (IR) is a pathophysiological condition related to diabetes and obesity. RS could reduce blood glucose and ameliorate IR in animals, but its effect in human population is controversial. Objective The authors conducted a systematic literature review to evaluate the effect of RS diet supplement on ameliorating IR in patients with T2DM and simple obesity. Methods Databases that supplemented with RS in ameliorating IR in T2DM and simple obesity were queried for studies on or before August 15, 2018. Parameters including fasting insulin, fasting glucose, body mass index (BMI), homeostatic model assessment (HOMA) etc. were extracted from studies to systemically evaluate effects of RS. Results The database search yielded 14 parallel or crossover studies that met the inclusion criteria. The results indicated that there was no significant difference in the amelioration of BMI, HOMA-%S and HOMA-%B in T2DM patients between RS and the non-RS supplementation. However, the fasting blood glucose, fasting insulin and HOMA-IR in T2DM with obesity who supplemented RS were lower than control group, and the subgroup analysis according to the dose of RS supplementation was inconsistency. There was no significant difference between RS and non-RS supplements in patients with simple obesity. Conclusion RS supplementation can ameliorate IR in T2DM, especially for the patients of T2DM with obesity, but not in simple obesity.

Abstract Background study of chemerin level in polycystic ovarian syndrome (PCO) patients and its relation to insulin resistance (IR). Upon chemerin on adipose tissue and glucose metabolism, serum chemerin has been recently studied in (PCO) women Aim We aimed to study the level of serum chemerin in PCO patients and its relation to insulin resistance. Methods The current study included 45 subjects with PCO syndrome and 45 healthy subjects as a control group. PCO subjects were divided into 27 obese PCO and 18 lean PCO. Control women were divided into 25 obese women and 20 lean women. Measurement of serum chemerin levels, fasting blood glucose (FBG),fasting insulin (FIN), total testosterone and pelvic ultrasonography Results Serum chemerin was significantly higher in the obese PCOS group (99.65 ± 13.72 ng/mL) compared with lean PCOS (87.99 ± 5,64 ng/mL) and the obese (76.82 ± 2.39 ng/mL) and non-obese (69.19 ± 8.40 ng/mL) control groups. In PCOS women, serum chemerin levels were positively correlated with Body mass index (BMI) (r = 0.835, P < 0.001), Fasting blood glucose (FBG) (r = 0.493, P < 0.005), Fasting insulin (FIN) (r = 0.913, P < 0.001), Homeostasis model assessment of insulin resistance (HOMA-IR) (r = 0.9181, P < 0.001). Conclusion There is an increase in serum chemerin level in PCOS patients with even more significant increase in patients with obese PCOS.

Abstract Background Gestational diabetes is the most common medical complication in pregnancy, and it has many side effects for the mother and the fetus. The aim of this study was to evaluate the effect of oat bran consumption on gestational diabetes. Methods This study is a randomized clinical trial that was performed on 112 women with gestational diabetes treated with diet. Participants were randomly divided into two groups of 56. Participants in both groups were given a diet for gestational diabetes. In addition to the diet, the intervention group received 30 g of oat bran daily for 4 weeks at lunch and dinner. Tests of fasting blood glucose and two-hour postprandial (2hpp) glucose were taken from both groups: before the intervention, and 2 and 4 weeks after the start of the intervention. Data analysis was performed using SPSS statistical software (version 22) using independent t-test, as well as Chi-square and Mann-Whitney tests. P values less than 0.05 were considered statistically significant. Results There was no statistically significant difference between the two groups in terms of mean blood glucose before the intervention, while 2 and 4 weeks after the intervention, mean fasting blood glucose and two-hour postprandial (2hpp) glucose decreased significantly in the intervention group compared with the control group (P < 0.001). Conclusion Based on the results of this study, the addition of oat bran to the standard diet for pregnant women with gestational diabetes reduced fasting blood glucose and two-hour postprandial (2hpp) glucose. More detailed studies with higher sample sizes are recommended to prove the effectiveness of this valuable dietary supplement. Trial registration IRCT registration number:IRCT20191220045828N1.

Abstract Objectives The objective of this study is to assess the effectiveness of a 6-month nutrition intervention to improve glycemic parameters and inflammation in prediabetic PLWH on stable ART with undetectable HIV viral load. Methods A 6-month randomized, controlled nutrition intervention was conducted in prediabetic PLWH. The study participants for the intervention were recruited from the Miami Adult Studies for HIV (MASH) cohort at the FIU-Borinquen Research Clinic. Upon their consent, the participants were randomized into the intervention group or the control group. Participants randomized in the intervention group met once a month for approximately 1 hour where they received medical nutrition therapy, nutrition counseling and nutrition education; participants randomized into the control group received educational material at baseline. Blood was drawn at baseline and at 6-month to measure fasting blood glucose (FBG) and high sensitivity C-reactive protein (hs-CRP). Results A total of 38 participants were recruited and randomized into either the intervention group (n = 20) or the control group (n = 18). We found that the FBG for the 6-month follow-up for the intervention group was significantly lower than the baseline FBG values of the same study group (paired t-test; P = 0.031). No significant difference was found in the control group between the baseline and 6-month fasting blood glucose values (P = 0.068). Moreover, no significant difference was found in pre/post C-reactive protein (CRP) levels in the intervention or control group (paired t-test; P = 0.404 and P = 0.117 respectively). There was a significant difference in CRP levels at baseline (P = 0.028) between the study groups but no difference at the 6-month follow up (Mann Whitney U test: P = 0.430). Conclusions The results from this intervention support the notion that a nutrition intervention is effective in prediabetic PLWH to lower diabetes risk by significantly lowering fasting blood glucose and may be implemented into larger scale interventions; however, no significant changes was seen in hs-CRP values between the 2 groups.

Aim: Antioxidants, such as vitamin C and vitamin E, is widely used as supplements. The aim of this study is to analyze the profile of blood glucose, serum insulin, and HOMA in active teenagers after vitamin C and vitamin E supplementation.Methods: Subjects (14-16 y.o) consisted of 12 boys and 5 girls, divided into 3 groups: control (4 boys, 2 girls), ‘moderate dose’ of vitamin C and vitamin E combination group (5 boys, 1 girls), and ‘high dose’ of vitamin C and vitamin E combination group (3 boys, 2 girls). The treatment was given for 5 days. Vitamin C and vitamin E for ‘moderate dose’ was 500mg; 200IU, and for ‘high dose’ was 1000mg; 400IU. Fasting Blood Glucose (FGB) and 1 hour BG (1hr_BG), fasting serum insulin (FSI) and 1 hour SI (1hr_SI) was collected after treatment. We also calculated the HOMA-IR and HOMA-β.Result: There was no significant difference on FBG, 1hr_BG, FSI, 1hr_SI, HOMA-IR, and HOMA-β (p≥ 0.05). However, mean FBG and 1hr_BG tended to be higher on the treatment groups. The control group had the lowest HOMA-IR and the highest HOMA-β.Conclusions: We suggest that the supplementation of vitamin C and vitamin E in active teenagers is not essential on glucose homeostasis.

Background: Although the results were conflicting, the Paleolithic diet (PD) was proposed to be effective in improvement of metabolic status. We aimed to conduct a systematic review and meta-analysis on the randomized controlled clinical trials (RCTs) evaluating the effects of PD on glycemic markers. Methods: Online databases such as PubMed, Scopus, Web of Science, and Google Scholar were searched up to December 2017 without any restrictions. The weighted mean difference (WMD) was also calculated using random effects model. Results: Eventually, eight good quality studies were included in the present systematic review and meta-analysis. The pooled analysis showed that although adherence to the PD led to reduction of fasting blood glucose (FBG) concentrations, it was no statistically significant (WMD = -0.31, 95% CI: -0.70, 0.07, P = 0.11). Moreover, compared with the control diets, the PD consumption did not significantly affect other glycemic markers such as 2-h post-prandial blood glucose (2h PBG), insulin, homeostasis model assessment for insulin resistance (HOMA-IR), and Hemoglobin A1c (HbA1c). Conclusions: Adherence to the PD had no significant effect on the glycemic markers, but reduction was observed in FBG levels.

Abstract Many studies have investigated the relationship between coffee and diabetes. Evaluation of the current evidence on the effect of coffee intake on diabetes is critical. Therefore, we aimed to investigate the potential association between green coffee extract (GCE) and fasting blood glucose (FBG), insulin and homeostatic model assessment of insulin resistance (HOMA-IR) by pooling together the results from clinical trials. PubMed, Scopus and Google Scholar were searched for experimental studies which have been published up to December 2018. Randomized controlled trials (RCTs) that investigated the effect of GCE supplementation on FBG, insulin and HOMA-IR in adults were included for final analysis. A total of six articles were included in the meta-analysis. Results revealed that GCE supplementation reduced FBG level (SMD: −0.32, 95% CI − 0.59 to − 0.05, P = 0.02) but had no effect on insulin levels (SMD: −0.22, 95% CI −0.53 to 0.09, P = 0.159). Although analysis showed that GCE supplementation cannot change the HOMA-IR status (SMD: −0.30, 95% CI −0.73 to 0.13, P = 0.172), after stratified studies by GCE dosage (< 400 mg/day versus > 400 mg/day) there was a significant decrease in HOMA-IR status in a dose greater than 400 mg. These findings suggest that GCE intake might be associated with FBG improvement.

Abstract Background: In order to recommend the optimum type of exercise for type 2 diabetes prevention, the effect of different exercise interventions on glycaemic control and insulin resistance relative indicators were compared. Methods: The studies involving the curative effect of aerobic exercise trailing (AET) or resistance trailing (RT) for prediabetes were searched with pre-established strategy . The Body Mass Index (BMI), fasting blood glucose (FBG), glycated haemoglobin (HbA1c), Insulin and homeostasis model assessment-insulin resistance index (HOMAIR) were used as outcomes indictors. Q statistic was calculated to evaluate the heterogeneity within studies. A fixed effects model was chosen for pooling data with p > 0.05, otherwise, a random effects model was chosen. The consistency test in this network meta-analysis was conducted by Node-splitting analysis. Results: A total of 12 eligible studies were included into this network meta-analysis. According to p score values, prediabetes individuals in AET group had better curative effect in BMI (p score = 0.7525), Insulin (p score = 0.6411) and HOMAIR (p score = 0.6411) value controls than in other groups, while the curative effect of RT on FBG (p score = 0.8465) and HbA1c (p score = 0.8550) values were optimum. The rank of P-scores for each indicator under above two effect models was basically consistent, indicating that our results of network meta-analysis were stable. Conclusions: AET might be a better intervene method for improving insulin resistance to prediabetes, while RT was more effective than AET, AET+RT or CT for glycaemic control in prediabetes.
