Abstract

OBJECTIVE: Hyperglycemia is associated with increased morbidity and mortality in diabetic patients following coronary artery bypass grafting. Tight glycemic control in perioperative period can reduce these events. The goal of this study was to determine whether combination of continuous infusion and subcutaneous glargine as a basal insulin could improve glycemic control. MATERIAL AND METHODS: Diabetic patients who were candidate for CABG were randomized to receive continuous insulin infusion with or without subcutaneous Glargine insulin for at least 72 hours which started 24 hours before surgery and continued for 48 hours after surgery. RESULTS: A total 84 subjects were required. In group A (n = 45) continuous insulin infusion was used for glycemic control and in group B (n = 39) we used continuous insulin infusion with sub‌cutaneous glargine insulin. Blood glucose level was significantly better in desirable range in group B in comparison to group A. Total mean blood glucose level in group A was 186.1 mg/dl and in group B was 174.3 mg/dl (P = 0.008). Frequency of hypoglycemia (blood glucose <70 mg/dl) was 0.66% in group A and 0.5% in group B that was similar (P = 0.530). The mean length of stay in the hospital was not different between two groups (P = 0.288). CONCLUSION: We found out that a combination of continuous insulin infusion and glargine insulin as main basal insulin can improve glycemic control in diabetic patients undergoing coronary artery bypass grafting.

Abstract

Objective: Measurement of glomerular filtration rate (GFR) is the best determinant in assessment of kidney function for diagnostic and therapeutic purposes. As extremely accurate methods of GFR measurement (i.e. Inulin clearance) are expensive and Time-consuming and due to limitations of the 24 hour urine collection method, some formula have been developed for the GFR measurement. Here we have compared the GFR calculated via CG or MDRD formulas and that measured by creatinine clearance in 24-hour urine collection method in diabetes patients with chronic kidney disease (CKD). Materials and Methods: This study was performed on 75 diabetes patients with stage 3 or 4 CKD (15-19 ml/min/1.73m2) in the nephrology clinics of the Yazd medical university. The GFR was measured via CG and MDRD formula and also via creatinine clearance in 24-hour urine collection method. Correlation test and Bland altman plot was utilized to check for the relationship between creatinine clearance and the GFR. Results: Results show a significant correlation of the GFR calculated via creatinine clearance in 24-hour urine collection with GFR calculated via CG (r= 0.75) and with MDRD (r=0.70) formulas. This correlation was even increased when serum levels of creatinine was >1.5 mg/dL or in patients with stage 4 CKD. Comparison of the differences between GFR calculated via CG or MDRD formulas and creatinine clearance in 24-hour urine collection method using Bland altman showed a lower bias (CG: 17.76 MDRD: 10.64 ml/min/1.73 m2) and narrower limits of agreement (MDRD: -11.33 – 32.62, CG: -4.68 – 40.20) to the creatinine clearance in 24-hour urine collection for the MDRD formula compared to that for the CG formula. Conclusion: CG and MDRD correlate well with creatinine clearance in 24-hour urine collection, while MDRD is more accurate in diabetes patients with stage 3 or 4 CKD.

Abstract

Abstract Objective: Previous studies have indicated the hyperglycemia-induce cell death in various tissues such as brain, kidneys, liver and especially in the testis. Recent studies have reported that diabetes can trigger male infertility. In this study we report the histological analysis of the testis tissue after diabetes type 1 induction in wistar rats. Materials and Methods: At various time intervals after diabetes type 1 induction, testicular cell was assessed in the controls and in the diabetic rats. Hyperglycemia was induced in male wistar rats by intraperitoneal injection of drug streptozotocin (STZ). At different time points (4, 6, 8 and 20 weeks) post diabetes type 1 induction, rats were euthanized and testicular tissues were removed for histological analysis. Their testes were fixed in formaldehyde (37%), embedded in paraffin and then sectioned (4µm thick). They were further deparaffinized, stained with Hematoxylin-Eosin (H&E) and DAPI, and observed under light and fluorescence microscope, respectively. Results: Histological results showed reduced cell density in testis, which indicates that diabetes type 1 and hyperglycemia conditions impair normal cell density in testis tissue. The changes in seminiferous tubules from 4 weeks to 20 weeks were also observed. The testicular histology of diabetic animals shows that the maximum reduction in cell density occurred after 20 weeks. Conclusion: The induced diabetic condition provides evidence that hyperglycemia plays an important role in pathogenesis of diabetes, and also indicated that chronic hyperglycemia eventually leads to cell death and male infertility. Probably, the consequent of inflammatory condition of hyperglycemia resulted in apoptotic-related gene products and testicular dysfunction which has an important implication for infertility, and offer new chances for therapeutic interventions.

Abstract

Objective: Patients with metabolic syndrome are prone to cardiovascular disease and diabetes. Regarding the importance of nutritional factors in management of metabolic syndrome, this study was designed to evaluate the effects of dark chocolate consumption on serum lipid profile in patients with metabolic syndrome. Materials and Methods: In this randomized clinical trial, 114 patients with metabolic syndrome, aged 30 to 60 years, without heart, renal and hepatic diseases were recruited. The eligible patients were randomly allocated to receive either dark chocolate (76% purity), 20 or 40 grams daily for two months. Total cholesterol, high-density lipoprotein (HDL), triglycerides (TG) and fasting blood glucose (FBG) were measured with enzymatic methods before and after intervention. A low-density lipoprotein (LDL) level was calculated by the Friedewald formula. Data were analyzed using SPSS version 16.0 and ANOVA test P<0.05 was considered significant. Dietary intake was measured with NUT4 software at the beginning and the end of the study. Results: There were no significant changes in dietary intakes of patients during the intervention in three groups. No significant differences were seen in mean concentration of lipid profile before and after intervention in groups (P>0.05). Conclusion: Consumption of 20-40g/day dark chocolate with 76% purity for 2 months doesn't change the lipid profile of patients with metabolic syndrome.

Abstract

Objective: The previous studies indicated that the TLRs especially Toll-like receptor 4) TLR4 (are involved in the process of diabetes. The aim of the present research was to investigate the time course expression pattern of TLR4-a main component of innate immune system- in mRNA levels in the heart tissue of diabetic male wistar rats.

Materials and Methods: In this research, adult Wistar rats (6-8 weeks old and 200-250 g weight) were mated and the pups were grown to 6-8 weeks old. Heart tissues were collected and analyzed by real-time PCR to evaluate the mRNA levels of TLR4. The mRNA levels of TLR4 in total heart tissue were evaluated in STZ-treated control rats in various times after diabetes induction.

Results: Results showed that the up-regulation of TLR4 during the time course after diabetes induction as compared to the control. The abundant expression of TLR4, a major component of innate immunity system, provides strong evidence that TLRs play important roles in the pathogenesis and expansion of diabetes and it is possible that the expression of TLRs eventually lead to cardiovascular disease.

Conclusion: The abundant expression of TLR4 which is major component of innate immunity system, provides strong evidence that TLRs play important roles in innate immunity and the pathogenesis and expansion of diabetes. It is possible that the expression of TLRs eventually lead to cardiovascular disease. The mechanisms for the increase in TLR expression and activity in diabetes have not been studied in depth. Modulating these TLRs could be beneficial in prevention of diabetic complications.

Abstract

Objective: In patients with diabetes mellitus, increased rate of lipoprotein oxidation and oxidative stress have important role in diabetic angiopathy, including nephropathy. We designed a study for comparing the level of Ox-LDL in diabetic patients with Macro-albuminuria, Micro-albuminuria, versus Normo-albuminuric.

Materials and Methods: One hundred and thirty five patients with type 2 diabetes mellitus who had been referred to the Yazd Diabetes Clinic, from 1391 through 1392, were enrolled to our study. The 24 hours urinary albumin excretion was measured and Macro-albuminuria defined as albumin excretion of greater than 300mg per day and below 30mg per day in normo-albuminuric group and between 30-300mg defined as Micro-albuminuria group. Plasma level of OX-LDL was measured.

Results: The plasma OX-LDL level in patients with Macro-albuminuria was higher than those in Normo-albuminuric group, (16.1±3.6 U/ml versus 8.6±1.7 U/ml). There was a significant correlation between the OX-LDL and urine albumin in Macro-albuminuria and Micro-albuminuria groups. There was no significant correlation between the OX-LDL and HbA1C level and diabetes duration.

Conclusion: Significantly elevated plasma OX-LDL in patients with Macro-albuminuria suggests that OX-LDL may play an important role in the progression of diabetic nephropathy.

Abstract

Objective: Nonalcoholic Fatty Liver Disease (NAFLD) is the most common form of liver disease in the world and it is one of the liver transplantation causes. The present study aimed to investigate the effect of Purslane seeds on anthropometric parameters, fasting blood glucose (FBS), and liver enzymes in patients with nonalcoholic fatty livers.

Materials and Methods: in this clinical trial, 54 patients with fatty livers were participated and randomly divided into two groups: the 1st group received 10 grams of purslane seeds per day along with a weight loss diet and the 2nd (control) group were only engaged in a weight loss diet. At the beginning and at the end of the 8th week of intervention, anthropometric parameters, FBS, liver enzymes and liver sonography were studied in both groups.

Results: After the intervention, significant reductions in weight, waist and hip circumference (P=0.01) were observed in both groups, but only the changes in hip circumference were significant between the two groups (P=0.01). Body mass index significantly reduced only in the purslane group (P<0.05). The average intake of energy, protein, carbohydrate, and fat was reduced in both groups (P<0.05). No significant changes occurred in the fasting blood glucose before and after the study in both groups; however, FBS was significantly different after 8 weeks compared with the control group (P<0.05). Purslane consumption after 8 weeks significantly reduced alanine aminotransferase (P=0.03) and aspartate aminotransferase (P=0.03) in the relevant group; yet the changes were not significant in the control group. Diet and purslane consumption were unaffected on alkaline phosphatase (ALP) levels. In both group liver steatosis decreased but in the purslane group was more significant.

Conclusion: This study showed that consumption of purslane seeds besides the diet for 8 weeks have beneficial effects on anthropometric parameters, FBS, liver enzymes and liver steatosis. Purslane consumption significantly reduced alanine aminotransferase and aspartate aminotransferase. Liver steatosis decreased in the purslane group more than control group.

Abstract

Objective Diabetes mellitus (DM) as a metabolic disorder is becoming a serious threat of health. In recent years, there has been renewed interest in the treatment against different diseases using medicinal plants. The present randomized clinical trial was carried out to evaluate the efficacy of Ziziphus in improving glucose control in women with type 2 diabetes mellitus (T2DM).

Materials and Methods: Women were randomized to treatment with Ziziphus (30 gr/day) or control group (age match). This trial was done during three months. Fasting blood sugar (FBS), 2-hour postprandial blood glucose (2hpp) and glycated hemoglobin (HbA1c) were measured before and after the intervention.

Results Ziziphus consumption was associated with significant reductions in serum levels of 2hpp glucose and HbA1c (P<0.05) in women with T2DM. As well as marginally significant effect was observed from Ziziphus of serum levels of FBS (P=0.06) after the intervention.

Conclusion: Consumption of Ziziphus for 3 months has anti-diabetic effects on women with T2DM. These findings suggest Ziziphus as a beneficial supplement for diabetic women.

Abstract

Objective: There are association between oxidative stress and incidence of some chronic diseases, such as type 2 diabetes mellitus (T2DM). Food containing antioxidant compounds, such as some spices, are the natural ways to deal with oxidative stress. The purpose of this study was to determine the effect of sumac powder (Rhus coriaria L) on the glycemic profile in patients with T2DM.
Materials and Methods: In this experimental study, 60 T2DM patients were selected and randomly divided into two groups: intervention and control groups. The intervention group received 2 packs of 3 grams sumac powder once a day for 3 months in two bowls of low-fat yoghurt for lunch and dinner and the control group received two bowls of low-fat sumac-free yoghurt  for lunch and dinner. Data collection was performed by a checklist at the beginning and end of the study and blood samples were collected. Data were analyzed using paired T-test and independent t-test. The significance level was considered at P<0.05.
Results: In this study, the fasting serum insulin levels decreased in the intervention group. But the mean changes of variables were not statistically significant between two groups. There was also no difference in other factors between the beginning and end of the study.
Discussion: This study showed that daily intake of 6 grams sumac powder for three months had no significant effect on the glycemic profile (fasting blood sugar and 2-hours post-prandial glucose and glycosylated hemoglobin A1C) and serum insulin levels of diabetic patients.
