Background and aims: Several studies have shown that genetic polymorphisms of the transcription factor 7-like 2 (TCF7L2) are highly associated with the development of type 2 diabetes mellitus (T2DM) and its associated complications in several populations. The aim of our study was to investigate the association of the rs7903146 (C/T) and rs12255372 (G/T) polymorphism in the TCF7L2 gene with the risk of developing T2DM in the Moroccan population. Material and methods: A total of 150 T2DM patients and 100 healthy controls were recruited for various anthropometric, biochemical and genetic parameters. Genotyping was performed by using Real Time-PCR. The frequency of genotypes, alleles, anthropometric measures, glycemia, glycated hemoglobin (HbA1c) were evaluated in patients and control, while lipid profile was available only for T2DM group. Results: Glycemia, HbA1c and body mass index (BMI) were significantly higher in T2DM group than control. Analysis of the distribution of the TCF7L2 rs7903146 genotype and allele revealed that the TT genotype was more frequent in T2DM group (24.0%) than in healthy controls (5%) (OR = 4.08, 95% confidence interval (CI = 1.95–11.80, p < 0.0001). The T allele was more frequent in diabetic patients (45.2%) than healthy control (34.5%) and it was associated with high risk of diabetes (OR = 2.13, 95% CI = 1.12–7.31, p = 0.005). The same results were found regarding rs12255372, TT genotype frequencies were 18,7% and 6.0% in T2DM and control group, respectively (OR = 3.11, 95% CI = 1.33–7.24, p = 0.004). The T allele was over-presented in diabetics compared to controls (45.3% and 38.0%, respectively) and increases the risk of T2DM (OR = 2.01, 95% CI = 1.04–3.10, p = 0.01). However, there was no significant difference between the three genotypes of rs7903146 and rs12255372 regarding age, BMI, glycemia, HbA1c and lipid profile. Conclusion: The present study confirmed a significant association of the TCF7L2 gene (rs7903146 (C/T) and rs12255372 (G/T) polymorphisms with a higher risk to T2DM in the Moroccan population. No significant difference in respect to anthropometric and metabolic parameters between different genotypes.

Abstract Background: Type 2 Diabetes Mellitus (T2DM) is a chronic metabolic condition with various genetics and environmental influences that affects the capacity of the body to produce or use insulin resulting in hyperglycemia, which may lead to variable complications. It is one of the world’s rising health problems. There is emerging evidence that some genetic polymorphisms can impact the risk of evolving T2DM. We try to determine the relationship of (rs7903146) variant of the Transcription factor 7-like 2 (TCF7L2) gene with T2DM and its microvascular complications.Methods and Results: This case-control study included 180 subjects: 60 diabetic patients without complications, 60 diabetic patients with microvascular complications and 60 matched healthy controls. Genotypes of rs7903146 (C/T) SNP in the TCF7L2 gene were evaluated by real-time polymerase chain reaction via TaqMan allelic discrimination. Logistic regression was used to detect the most independent factor for development of diabetes and diabetic microvascular complications. Variant homozygous TT and heterozygous TC genotypes were significantly increased in diabetic without complications and diabetic with complications groups than controls (p=0.003, 0.001) respectively. The T allele was more represented in both patient groups than controls with no significant difference between patient groups. TT genotype as well as T allele was significantly associated with increased T2DM risk.Conclusion: The T allele of rs7903146 polymorphism of TCF7L2 confers susceptibility to development of T2DM. However, no significant association was found for diabetic complications.

Transcription factor 7-like 2 (TCF7L2) variants are known risk factors of type 2 diabetes (T2DM).However, this association is not consistent among different populations. The current study aimed at investigating the relationship between rs 7903146, rs 12255372 variants of TCF7L2 and susceptibility to T2DM and different metabolic parameters in a cohort of Egyptian type 2 diabetic patients. This case control study included 60 diabetic patients and 60 matched unrelated healthy controls. Genotyping was performed by using Real Time-PCR. The frequency of genotypes, alleles, anthropometric measures, glycemic indices, HOMA-IR and lipid profile were evaluated in patients and control. Regarding rs 7903146, TT genotype was more frequent in healthy controls (43.3%) than diabetic patients (20%) (OR = 0.291, 95% CI = 0.108-0.788, P = 0.015). T allele was more frequent in healthy control (61.7%) than diabetic patients (44.2%) and it was associated with lower risk of diabetes (OR = 0.492, 95% CI = 0.294-0.823, P = 0.007).However, there was no significant difference between patients with CC, CT and TT genotypes of rs7903146 regarding HbA1C (p=0.549), HOMA-IR (p=0.359), total cholesterol (p=0.482). In contrast, T allele of rs12255372 had no significant relation to diabetes risk (OR = 0.602, 95% CI = 0.361-1.005, P = 0.052). There was no statistically significant difference of frequency of any rs12255372 genotypes between cases and controls In addition, patients with GG,GT, TT genotypes of rs12255372 had no significant difference regarding HbA1C (p=0.393), HOMA-IR (p=0.985), total cholesterol (p=0.368). The study confirmed the association of TCF7L2 (rs 7903146) and T2DM, while failed to detect any association between TCF7L2 (rs 12255372) and susceptibility to T2DM. No significant difference in respect to metabolic parameters between different genotypes of rs7930146 and rs12255372.

Iron Concentrations

Recent studies have been showed important role of elevated iron levels in pathogenesis of Type 2 Diabetes mellitus (T2D) and insulin resistance. The aim of this study was to determine serum of free iron concentration in T2D patients and find out associations with lipid profile. The study included 51 participants (27 healthy control and 24 no treated diabetes patients), with ages from 45 to 65 45-65 ages and both gender. As expected, concentrations of serum iron were elevated in diabetic patients compare to healthy subjects while statistical significant difference were shown between iron levels in control group and group with good control of glycaemia (p<0.05). In addition, there was a significant positive correlation between free iron concentration and LDL cholesterol levels and negative significant correlation between iron concentrations with HDL cholesterol in diabetics (p<0.05). These findings suggest that increase serum of free iron concentrations may have an important role and influence in development of disease, especially in lipid metabolism and profile as well in risk of further complications of diabetes.

Background: The two important endocrinopathies, diabetes mellitus and thyroid dysfunction are interrelated to each other where the correlation is poorly understood. The thyroid dysfunction is more frequent in diabetics than general population. The present study was aimed to know the prevalence of thyroid dysfunction in type 2 diabetes mellitus (T2DM) and its association with controlled and uncontrolled T2DM.Methods: A retrospective study of 600 T2DM patients between 13-60 years of age with known thyroid status were included and the following parameters were examined: age, sex, body mass index (BMI), fasting blood sugar (FBS), HbA1C, free triiodothyronine (fT3), free tetraiodothyronine (fT4) and thyroid stimulating hormone (TSH).Results: The prevalence of thyroid dysfunction in T2DM patients was found to be 26.5% whereas 9% in healthy controls. Significantly elevated levels of FBS, HbA1C and TSH were observed whereas the levels of fT3, fT4 were found to be low in patients when compared to controls. Subclinical hypothyroidism (SCH) in diabetics (both controlled and uncontrolled) was more prevalent (15%) than it was found in healthy controls (5%). Similarly, overt hypothyroidism was also found to be high in diabetic patients (6%) as compared to healthy controls (2%). Significant difference (p <0.05) in the levels of TSH was found between group I (Controlled T2DM) and II (uncontrolled T2DM patients), also between groups II and III (Controls). Group II patients were found to have significant low levels of fT3 as compared to other two groups (Group I and III) (p<0.005).Conclusions: As SCH is more frequent in T2DM diabetes mellitus and untreated SCH patients have higher rate of complications, periodical screening is advised for thyroid dysfunction to prevent micro vascular and cardiovascular complications.

Abstract Study aim: This study aimed to investigate the effect of aerobic training (AT) and pomegranate juice intake (PJI) on the lipid profile in men with type 2 diabetes. Materials and methods: This randomized clinical trial was performed in middle-aged men (40–50 years old) with type 2 diabetes. Participants were randomly assigned into four groups: AT + PJI (n = 9); AT (n = 10); PJI (n = 9), and control (C) (n = 10). The AT program consisted of 60-75% of HRMax, 40-60 min/day, three days/wk for eight weeks. Participants in the PJI group consumed 240 ml of pomegranate juice (sugar or additive-free) daily for eight weeks. Lipid profile was measured at the beginning and end of the study. The data were analyzed through paired t-test and one-way analysis of variance, as well as Tukey’s post hoc test at the signification level of P<0.05. Results: AT + PJI, PJI, and AT groups demonstrated significant improvements in lipid profile compared to the C group. The results show that the AT + PJI group had significantly lower TC and LDL (p = 0.001 and p = 0.002, respectively), and significantly higher HDL (p = 0.023) compared with the PJI group. There was no significant difference between AT and PJI groups. Also, TG was significantly lower in AT+ PJI compare to the C group. Conclusions: AT + PJI is more effective than AT or PJI alone in the improvement of lipid profile in patients with type 2 diabetes.

Introduction: Sport activity leads to metabolic and physiological adaptations, which may have a beneficial role for diabetic patients. The purpose of this study was to compare the effects of low volume and high volume high-intensity interval training (HIIT) on serum leptin and some of the lipid profiles of type 2 diabetic men. Materials and Method: In this randomized clinical trial, 30 males with type 2 diabetes mellitus were divided into three groups of 10, including low volume and high volume HIIT and control groups. The low volume groups underwent intensive training for up to two minutes and a high volume group up to six minutes for 8 weeks. Blood lipid profile indicators were measured before and 48 hours after the last exercise session. The paired t-test, ANCOVA and LSD as a post hoc test were used to analyze the data. Results: There was a significant difference before and after 8 weeks of low-volume HIIT training at triglyceride (p = 0.049). However, there was no significant difference in serum leptin, cholesterol, LDL-C, and HDL-C in men with type 2 diabetes (p > 0.05). ANCOVA only found a differences between groups on BMI (F2, 26 = 3.61, p = 0.041). Also, the post hoc in two by two comparisons of HDL showed that there was a significant difference between high volume HIIT and control groups (p = 0.021) and low volume and control group (p = 0.011). The HDL-C levels in HIIT training groups increased significantly compared to controls. Discussion: Considering other proven adaptations of HIIT training on triglyceride, HDL and improving glycemic indexes is a useful and safe training for type 2 diabetic patients. Therefore, needing a very short time for this training, metabolic, functional and physiological adaptations of HIIT training, along with other exercises are recommended to improve the condition and reduce the risk of cardiovascular disease and complications of type 2 diabetes

Background: Type 2 diabetes needs a better understanding of etiological factors and management strategies based on lifestyle and constitutional factors, given its high association rate with many cardiovascular, neurological disorders, and COVID-19 infection. Purpose: The present study was undertaken to investigate the effect of Diabetes-specific integrated Yoga lifestyle Protocol (DYP) on glycemic control and lipid profiles of diabetic adults. Along with the DYP intervention, the individuals residing in Chandigarh and Panchkula union territories in the northern part of India were assessed for Ayurveda-based body–mind constitutional type. Ayurveda describes body–mind constitution as “ prakriti,” which has been discussed from two angles, namely physiological and psychological as body and mind are correlated. Methods: Cluster sampling of waitlist control study subjects was used as the sampling method for the study. A total of 1,215 registered subjects (81 diabetic) responded in randomly selected clusters in Chandigarh and Panchkula. Ayurveda physicians did Ayurveda body–mind constitutional assessment called prakriti assessment (physiological body–mind constitution assessment) in 35 participants (23 diabetic, 12 prediabetic) as a part of the study. Results: A group of 50 subjects was randomly selected for yoga intervention out of 81 diabetes mellitus adults, and 31 subjects were enrolled as waitlist controls. A significant decrease in the glycosylated hemoglobin levels from 8.49 ± 1.94% to 7.97 ± 2.20% in the intervention group was noticed. The lipid profiles of the DYP intervention and control groups were monitored. Three-month follow-up results of lipid profile diagnostic tests in intervention and control groups showed a significant difference between the two groups ( P < 0.05). Most diabetic and prediabetic individuals were found to have pitta dosha ( pitta controls all heat, metabolism, and transformation in the mind and body) as dominant constitution type. Conclusion: The study results demonstrated significant positive effects of yoga in diabetic individuals. This study has indicated the evidence for the safety and efficacy of the validated DYP for community-level interventions to prevent maladies like brain damage and stroke.

<p>In addition to known risk factors, the role of different micronutrients such as selenium in diabetes incidence has been proposed. Some previous studies have shown an association of selenium deficiency and type 2 diabetes mellitus, while other studies have not confirmed such a relationship. The aim of this study was to evaluate serum level of selenium in patients with Type 2 diabetes compared with the control group. This cross-sectional study was carried out on patients with type 2 diabetes in Zahedan, southeastern Iran. One hundred newly diagnosed type 2 diabetic patients were evaluated for serum selenium level. One hundred subjects from the general population who had normal fasting blood sugar levels were selected as the control group. The control group subjects were matched in pairs with each of patients on the basis of sex, age (± one year), and body mass index (±1). Serum level of selenium was determined by spectrometry method. Results were compared using t-test. The mean serum level of selenium in patients was 94.47±18.07 µg/L whereas in control group was 142.79±23.67 µg/L. The mean serum level of selenium was significantly different between the two groups (P&lt;0.001). Serum levels of selenium in diabetic patients with significant difference statistically were lower than the control group. In order to evaluate serum level of selenium in patients with diabetes, studies with larger sample size are required. Likewise, prospective studies along with selenium supplementation and investigating its effect on incidence of diabetes are accordingly needed.</p>

Polymorphisms of the Calpain10 and TCF7L2 genes were identified as possible type 2 diabetes susceptibility genetic markers. We conducted a case-control study to evaluate the relation between SNP43 of calpain-10 and rs12255372 and rs7903146 in the TCF7L2 with type2 diabetes in western-north of Iran. The role of these variants in Iranian population was less clear. A total of 202 patients and healthy controls were enrolled to analysis the frequency distribution of Calpain10 and TCF7L2 polymorphisms (SNP43, rs12255372 and rs7903146) using polymerase chain reaction-restriction fragment length polymorphism (PCR - RFLP) method. The frequency of allele A in controls was significantly greater than that of diabetic patients (P=0.031), whereas the difference between distribution of SNP43 genotypes (A/A, A/G, G/G) were non- significant in case and control groups. Non significant association was also observed between G/G, A/G or A/A genotypes and type 2 Diabetes. The frequency of the ?T? allele of rs12255372 (G/T) was significantly associated with type 2 diabetes (OR= 0.55, 95% confidence interval [CI], 1.11-1.51; P<0.001). No allelic association was found for rs7903146(C/T) polymorphism. The distribution of alleles in case and control groups are significantly different indicating the G allele is associated with type 2 diabetes. The rs12255372 (G/T) may be associated with type 2 diabetes.
