Abstract
Background: Type 2 diabetic patients have higher risk for death from coronary heart diseases than non-diabetic patients. Studies have revealed showed intensive treatment of hyperglycemia only have a small effect on CVD risk. Other risk factors such as Lipid abnormality play a leading role in the increased CVD risk associated with diabetes. The aim of this study was to assess the quality of lipid control and treatment in type 2 diabetic patient with dyslipidemia.
Methods: We studied Data from 602 type 2 diabetic patients who had at least four regular clinic visits every year for medical care in outpatient clinics of Isfahan Endocrinology and Metabolism Research Center, 1999-2003. Patients for Classified in three groups according to lipid levels as low, moderate and high risk. ADA )American Diabetes Association) standard criteria were used for appropriate lipid control.
Results: The mean age, duration of diabetes, HbA1c and BMI were 52.2±9.5 years, 6.8±4.6 years, 9.2±1.7% and 29.4±4.2 Kg/m2 respectively at initial registration. Eighty four percent of patient had LDL cholesterol above 100 mg/dl and 71% had triglyceride level >150 mg/dl, of these patients 47.8% and 41.6% had high risk levels and only 12.4% taking statins and 21.5% taking fibrate for treatment at end of study. Among hyperlipidemic patients levels of LDL-C decreased from 170.8±35.6 mg/dl to119±30.20 (p < .001), triglyceride decreased from 273.8±126 to225.2±97 mg/dl (P<0.004) and HDL-C increased from 43.3±10.6 to 48.4±14.1mg/dl ((P<0.6). Percentage change of lipid level was -35.8%, -17.7% and +7.3% respectively. At the end of fallow-up 50.4% of patients treated with statins and 14.7% with fibrate. Finally, overall control of cholesterol and triglyceride in patients with dyslipidemia was 30% and 37% respectively.
Conclusion: Our findings showed that many of type 2 diabetic patients with dyslipidemia have inadequate control of lipid and lipoprotein. The prevalence of cardiovascular events due to hyperlipidemia in type 2 diabetic patients is high. This fact demonstrates the importance of early interventions for control and treatment these risk factors for prevention of cardiovascular complication in this patients.

Abstract
Background: The prevalence of Diabetes mellitus as the most common metabolic disorder of human is progressively increasing. Dyslipidemia is common among diabetic patients characterized by elevated plasma TG, LDL-C and reduced HDL-C levels which increase risk of cardiovascular events. Fish oil supplement which contains omega-3 has been proposed to correct the atherogenic lipid profile associated with diabetes mellitus. Doubt remain whether the net effect of fish oil supplement on lipid profiles are beneficial in diabetes. We therefore performed this randomized double-blind clinical trial to investigate this.
Methods: Ninety six patients with type 2 diabetes mellitus were randomized assigned to take 3 times daily supplementation (capsule) with either fish oil or corn oil for 8 weeks (48 patients in each group). At begining also end of study we measured laboratory variables (FBS, TG, Total cholesterol, LDL and HDL) in both groups.
Results: At begining of the study demographic and laboratory measurements were similar in both groups (P>0.05).At 8th weeks there were no statistically significant differences in variables measured except for LDL and HDL in fish oil group that leads to increase and decrease respectively. Although both groups show improvement in LDL / HDL and Total cholesterol / HDL ratios but mean charges were statistically significant in fish oil as compared with corn oil group. (P=0.001, P=0.005 respectively).
Conclusion: Fish oil supplement showed statistically significant improvement in LDL/HDL, Total cholesterol/HDL ratios as compared with corn oil. This may leads to decrease cardiovascular events.

Abstract
Background: Only limited data are available on the benefits of fruits and vegetable consumption on CVD risk factors. The aim of this study was to examine whether and to what extent intake of fruits and vegetables are inversely associated with cardiovascular (CVD) risk factors in adults.
Methods: In this population-based cross-sectional study a representative sample of 840 Tehranian adults (361 men and 479 women) aged 18-74 years were randomly selected in 1998. Usual dietary intake was assessed with the use of food frequency questionnaire. Portion sizes of consumed foods were converted from household measures to grams and analyzed by using Nutritionist III software designed for Iranian foods. Subjects were categorized based on category cut-points. : 0-1.9, 2-2.9, 3.0-3.9, and>=4 servings/d.
Results: In multivariate logistic regression after adjusting for confounders, dietary fruits and vegetable were found to be significantly and inversely associated with CVD risk factors. Adjusted odds ratio for high LDL concentrations were 1.00, 0.88, 0.81, 0.75(P for trend < 0.01) in first model which was adjusted for age, body mass index (BMI), energy intake, smoking status, dietary cholesterol, and prevalence of diabetes mellitus and coronary artery disease, a trend which was not appreciably altered by additional adjustment for education, physical activity, and saturated, polyunsaturated, total fat, Potassium and vitamin C intakes. This association was observed across categories of smoking status, physical activity, and tertiles of the Keys score.
Conclusion: Consumption of fruits and vegetables more than 4 servings a day is associated with lower concentrations of total cholesterol and LDL-C and with decrease in the risk of cardiovascular diseases.

Abstract
Background: Use of medicinal plants for attenuation of hyperglycemia and restoration of lipids to normal levels is very important. The effect of oral administration of Vaccinium myrtillus (VM) on serum glucose and lipids in diabetic rats was investigated.
Methods: Female Wistar rats were divided into 4 groups: control, VM-treated control, diabetic, and VM-treated diabetic groups. The treatment groups received oral administration of plant-mixed food (6.25%) for 4 weeks. Serum glucose, triglyceride, total cholesterol, LDL- and HDL- cholesterol levels were determined before the study, and at 2nd and 4th weeks after the study.
Results: Serum glucose level in diabetic group increased 2 and 4 weeks after the experiment as compared to data one week before the study (P<0.001) and VM treatment of diabetic rats did have a significant hypoglycemic effect (P<0.01). In addition, triglyceride level in diabetic group increased 4 weeks after the experiment in comparison with related data one week before the study (P<0.05) and there was a significant lower level of triglyceride in VM-treated diabetic rats (P<0.05). Furthermore, there was no significant changes regarding serum total cholesterol, HDL- and LDL- cholesterol levels in treated diabetic group as compared to untreated diabetic group.
Conclusion: Oral administration of VM has a significant hypoglycemic effects and leads to an appropriate changes only in triglyceride level.

Abstract
Background: There are growing concern globally regarding fast food consumption and its
related cardiometabolic outcomes. In this study we investigated whether fast food
consumption could affect the occurrence of metabolic syndrome after 3-years of follow-up in
adults or not.
Methods: This longitudinal study was conducted in the framework of Tehran Lipid and
Glucose Study on 1476 adults, aged 19-70 years old. The usual intakes of participants were
measured using a validated semi-quantitative food frequency questionnaire at baseline.
Biochemical and anthropometric measurements were assessed at baseline (2006-2008) and 3
years later (2009-2011). Multiple logistic regression models were used to estimate the
incidence of the MetS in each quartile of fast food consumption.
Results: The mean age of participants was 37.8±12.3 years old, and the mean BMI was
26.0±4.5 kg/m2
at baseline. Participants in the highest quartile of fast food consumption were
significantly younger (33.7 vs. 43.4 years, P <0.01). Higher consumption of fast food was
accompanied with more increment in serum triglyceride levels after the 3-year follow-up
(10.6±2.3 vs. 4.4±2.3 percent in the fourth and first quartile, respectively, P<0.01). After
adjustment for all of the potential confounding variables, the risk of metabolic syndrome, in
the highest quartile of fast foods compared with the lowest, was 1.85 (95% CI= 1.17-2.95).
Conclusion: We demonstrated that higher consumption of fast foods had undesirable effects
on metabolic syndrome after 3-years of follow-up in Iranian adults.

Abstract
Background: The prevalence of non-communicable disorders such as metabolic syndrome (MetS) is high in developing countries. Metabolic syndrome is a disorder of energy utilization and storage, diagnosed by a co-occurrence of three out of five of the following medical conditions: abdominal (central) obesity, elevated blood pressure, elevated fasting plasma glucose, high serum triglycerides, and low high-density cholesterol (HDL) levels. The present review aims to discover the genetic variant reported in association with MetS. Methods: The database for genotypes and phenotypes (dbGaP) and the database for genetic associations and human genome (HuGE navigator) were utilized in order to search for genes and their corresponding polymorphisms related to MetS. Additionally, an electronic literature search for other Iranian studies and the genetic aspect of TLGS was completed using PubMed. Results: For phenotype selection in PheGenI, 30 traits were chosen and after the analysis, 21 of them were in common results with MetS. After finding the common variation between traits and MetS, omitting the repeated SNPs, 173 variations were remained. Finally, results distinguished six of the most important genetic regions found to have strong association with MetS. Conclusion: Identifying major genes that are responsible for the metabolic syndrome may improve the medical care for treating individuals with metabolic syndrome, and eventually may lead to personalized medicine in which treatment is tailored genetically to the patient’s needs. The present candidate regions is a respectable start to replicate genetic studies in large affected Iranian individual which we hope leads us to improve our medical care in this field.

Abstract
Background: The scavenger receptor class B type I (SR-BI), as the high density lipoprotein cholesterol (HDL-C) receptor, is a key component in the reverse cholesterol transportation. The objective of this study was to assess the association between exon1 (G→A) polymorphism of SR-BI gene and lipid profiles among the Tehran Lipid and Glucose Study (TLGS) population.
Methods: This cross-sectional study included 774 adults (322 males and 452 females) aged 20–70 years, who were randomly selected from among TLGS population. Anthropometrical and biochemical variables for participants were measured. Selected SR-BI gene polymorphism was determined with restriction fragment length polymorphism (RFLP) using the Alu restriction enzyme.
Results: according to the results of current study, in the Tehran population, the allele frequency of SR-BI (G→A) polymorphism was 0.159 for an allele (minor allele) and 0.841 for G allele. Allele frequencies were in conformity with Hardy–Weinberg equilibrium. The result of this study showed that Subjects with the less common allele (allele A), after adjusting for age, have lower HDL-CandHDL3concentrations (p=0.046, p=0.041 respectively).
Conclusion: lipid disorders are caused by the interaction of environmental and genetic factors; therefore, exon1 (G→A) polymorphism of SR-BI gene could not be the only cause for the abnormality in the HDL-C levels. In future, this polymorphism may be use as a molecular marker for diagnosis.

Abstract
Background: Skeletal muscle as an endocrine tissue is involved in the regulation of metabolic activity, production and secretion of hormones including myokines. The aim of the present study was to investigate the effect of eight weeks of aerobic training combined with ethanol consumption on plasma lipid profile and glucose levels, triglyceride content and mayonectin, irisin and leptin gene expression in the gastrocnemius muscle in male rats.
Methods: A number of 32 rats with a weighing average of 200 ± 10 g were divided into four groups control, aerobic training, ethanol with dose of 4 g/kgbw, and ethanol +aerobic training. At the end of the period, values of lipid profile and plasma glucose, the amount of triglyceride of the gastrocnemius muscle and the relative levels of mayonectin, irisin and leptin gene expression were evaluated. Data were analyzed using two-way ANOVA.
Results: The plasma triglyceride levels in the aerobic training and ethanol+aerobic training groups were significantly decreased compared to the control group (P≤0.05). The gastrocnemius muscle triglyceride values were significantly increased in the ethanol +aerobic training (P≤0.0001) and aerobic training groups (P≤0.01) compared to the control group. The results showed that aerobic training significantly increased myonectin gene expression in aerobic training group (P≤0.05), but the expression of irisin and leptin genes did not change significantly in different groups.
Conclusion: Aerobic training during the eight-week was able to improve lipid content, especially plasma triglyceride and skeletal muscle triglyceride, and possibly regulate body metabolism by altering the levels of myokines, especially myonectin.

Abstract
Background: The release of adipokines from adipose tissue depots plays a key role in regulating metabolic homeostasis and several other physiological processes, including diabetes, obesity, and vascular diseases. This study investigated the effect of eight weeks of high intensity interval training (HIIT) on asprosin, lipid profile and insulin resistance in type 2 diabetic male rats.
Methods: 24 male Sprague Dawley rats were randomly divided into four equal groups: control (C), control traning (C+T), diabet (D) and diabet traning (D+T). Diabetes was induced by the combined method of high fat diet and low dose strepotozocin injection. The traning group performed the HIIT program on the treadmill for eight weeks. Data were analyzed using one-way ANOVA and bonferroni post hoc test at a significance level of P<0.05.
Results: The results showed increased plasma asprosin in D group compared to C (P=0.0001) and decreased in C+T group compared to C (P=0.03) and D+T group compared to D (P=0.04). There was no significant difference in HOMA-IR between the C and C+T group (P=0.9) but decreased in D+T compared to D (P=0.0001). HDL increased in D+T group compared to the D (P=0.0001) and decreased TG and LDL (P=0.001). There was no significant difference between TG and LDL in the C group compared to the C+T, but HDL increased in C+T (P=0.01).
Conclusion: Plasma asprosin increases in rats with type 2 diabetes and HIIT can reduce the complications of diabetes by improved lipid profile and reduce asprosin and insulin resistance.

Abstract
Background: Metabolic syndrome in obese children and adolescents raises the risk of cardiovascular disease and type 2 diabetes. Research suggests that exercise training may improve cardiometabolic health in this population. This meta-analysis aims to evaluate the impact of exercise on these risk factors in children and adolescents with metabolic syndrome., and behavioral outcomes in children and promoting awareness, self-care skills, and quality of life in families.
Methods: A systematic search of English and Persian articles was conducted from PubMed, Web of Science, and Scopus databases without time limits until May 2024. In data analysis, a random-effects model was used to calculate the weighted mean difference (WMD), standardized mean difference (SMD) and 95% confidence interval (CI). Also, heterogeneity of studies was assessed with the I² test.
Results: The results of 6 studies involving 1,761 participants demonstrated that exercise training led to significant reductions in body weight [WMD = −6.32 kg, P=0.001], waist circumference [WMD = −9.11 cm, P=0.001], LDL [WMD = −0.52 mmol/L, P=0.001], TC [WMD = −0.65 mmol/L, P=0.001], serum TG [WMD = -0.56 mmol/L, P=0.001)], fasting glucose [WMD = −0.19 mmol/L, P=0.03], fasting insulin [SMD = −1.01, P=0.001], and HOMA-IR [WMD = −1.60, P=0.001] compared to the control group in obese children and adolescents with metabolic syndrome.
Conclusion: Exercise interventions significantly reduce body weight, waist circumference, and blood pressure, while improving lipid profiles, including serum LDL, TC, and TG levels, in obese children and adolescents with metabolic syndrome. However, these interventions exhibited no significant impact on serum HDL concentrations. Consequently, to reduce cardiovascular risk factors and improve metabolic conditions, it is essential to implement long-term exercise interventions.

Abstract
Background: The aim of the present study was to investigate the effect of high-intensity interval training on lipid profile, fasting blood glucose, body composition, and Vo2max in patients with type 2 diabetes or obesity.
Methods: The type of research conducted is a systematic meta-analysis review. A systematic search of published articles was conducted from PubMed, Web of Science, Scopus, Sid, and Magiran databases up to January 2024. The mean difference and 95% confidence interval (CI) were calculated using a random-effects model. Heterogeneity was assessed using the (I2) test and publication bias was assessed using visual analysis of funnel plots and Egger's test.
Results: The results showed that high-intensity interval training significantly reduced body fat percentage [standard mean difference (SMD)=-0.796, P=0/001], BMI (SMD=-0.378, P=0/001), WHR (SMD=-0.424, P=0/001), LDL (SMD=-0.694, P=0/001), TC (SMD=-0.495, P=0/001), TG (SMD=-0.317, P=0/001) and fasting blood glucose (SMD=-0.557, P=0/001) in patients group compared to the control group had a significantly higher VO2max. However, high-intensity interval training significantly increased Vo2max (WMD=-0.997, P=0/001), and HDL (WMD=-0.558, P=0/001) in patients group compared to the control group.
Conclusion: Based on the results obtained, high-intensity interval training can have a positive effect on metabolic indices, body composition, and aerobic capacity in patients with type 2 diabetes or obesity and improve the condition of these individuals. Therefore, it is suggested that in medical centers for diabetic and obese patients, under the supervision of sports and medical specialists, the beneficial effects of high-intensity interval training should be utilized and used as an auxiliary strategy for the treatment and improvement of these individuals.

Abstract
Background: Dietary acid load is thought to contribute to the development of metabolic syndrome through effects on acid–base balance with evidence being inconsistent. This study aimed to examine the associations between dietary acid load indices, Dietary Acid Load (DAL), Potential Renal Acid Load (PRAL), and Net Endogenous Acid Production (NEAP) and risk of metabolic syndrome and its components in an Iranian adult cohort.
Methods: 6,482 adults aged 35-65 years were enrolled from the Mashhad Stroke and Atherosclerosis Study. Dietary intake was assessed using a validated food frequency questionnaire, and dietary acid load indices were calculated. Participants were followed for nearly 10 years. Logistic regression models were used to evaluate associations of DAL, PRAL, and NEAP with the incidence of metabolic syndrome, diabetes, hypertension, and dyslipidemia, adjusting for major confounders.
Results: Following adjustment, no significant associations were found between DAL indices and the incidence of metabolic syndrome or its components. DAL odds ratio (OR) for the highest versus lowest tertile was 0.984 [95% confidence interval (CI): 0.815–1.188; p= 0.868]. For PRAL, the OR was 1.024 (95% CI: 0.865–1.212; p= 0.782), and for NEAP, the OR was 0.902 (95% CI: 0.763–1.066; p= 0.227). None of the indices were significantly related to new cases of diabetes, hypertension, or dyslipidemia (all p> 0.05).
Conclusion: In this Iranian adult cohort, DAL indices were not associated with the risk of metabolic syndrome or its components. Further studies in populations with different dietary habits are needed to clarify potential threshold effects or effect modifiers.
