Background: Metabolic syndrome (MetS) is associated with an increased risk of cardiovascular disease and all-cause mortality. Zinc (Zn) is an essential trace element for the synthesis, storage, and release of insulin. The relationship between serum Zn and MetS is controversial. In this study we have evaluated whether serum Zn levels are associated with hsCRP level according to MetS phenotypes. Method: A total of 9493 individuals (3768 men and 5635 women) were recruited as part of the Mashhad Stroke and Heart Association Disorder (MASHAD) study. We measured the concentration of serum Zn by flame atomic absorption (Varian AA240FS) and we divided the subjects into quartile of serum Zn. We used SPSS version 18 statistical analyses for all. GraphPad Prism 6 for figures was used.Results: In this study there were significant differences between quartiles of Zn according to sex. The results showed that the level of serum hs-CRP were higher in subjects with metabolic syndrome who also had a serum Zn >95 µg/dl. In subjects with serum Zn Conclusion: Serum hs-CRP concentrations were related to MetS phenotypes. This relationship was modified by serum Zn level. According to the number of MetS components serum Zn levels decreased as the number of MetS component increased, and low serum zinc levels (Q1) showed an overall greater prevalence of MetS.

Cardiovascular disease (CVD), one of the main mortality causes worldwide is considered to be affected by general oxidative stress and inadequacy antioxidant system. Superoxide dismutase 1 (SOD1), a cytosolic antioxidant enzyme has a key role in neutralizing the excessive prooxidant by scavenging the super oxide anions. SOD1 polymorphic variants exhibit the altered activity properties. In the current study, we are aimed to investigate the association between the SOD1 polymorphism and CVD prevalence. A 6-years case control follow up study was designed to genotype the 526 participants (311 controls and 215 cases) for studying the 50 bp INS/DEL polymorphism at SOD1 promoter gene and analyze their blood lipid profile and anthropometric characteristics. Among the two possible alleles of the SOD1 gene (Wild [W] and Mutant [M]) the meaningful association was detected between the Mutants' frequency and the prevalence of CVD patients (p-value

Objective Postmenopausal women are at an increased risk of Cardiovascular Disease. We aimed to investigate whether this risk differed between individuals with a naturally occurring and other reasons for menopause within a large population-based Iranian sample. Study Design A total number of 1763 postmenopausal women (defined by amenorrhea for more than a year, or FSH > 30-40 mIU/ml), 900 of them with a natural menopause and 863 of them with other reasons for menopause caused by (hysterectomy without oophorectomy or one side oophorectomy, hysterectomy with oophorectomy or two side oophorectomy without hysterectomy) were recruited as part of the Mashhad Stroke and Heart Atherosclerotic Disorders (MASHAD) cohort study. Biochemical and hematological risk factors were measured in all the subjects and the data were analyzed by SPSS software version 20 Results There was a significant difference in the presence of cardiovascular disease in the natural menopause group compared with other reasons for menopause group (p

Background Normal weight obesity (NWO) is defined by a normal body mass index (BMI) but a high percentage body fat (%BF) composition. We aimed to examine the hypothesis that subjects having NWO are at higher risk for cardio metabolic abnormalities compared to normal body weight subjects with low body fat content. Method In this cross sectional study 2439 adults' normal body Mass Index were recruited as part of the Mashhad Stroke and Heart Atherosclerotic Disorders (MASHAD) cohort study. We measured 6 cardio-metabolic risk factors: Low-density lipoprotein cholesterol (LDL-C), triglycerides (TGs), and high-density lipoprotein cholesterol (HDL-C), fasting blood glucose (FBG), systolic and diastolic blood pressure, and serum C-reactive protein (hs-CRP). Two models were evaluated: in model A, the categorization of individuals utilized cut off values of BMI: 18.5–25 and %BF: > 25 in men and >30 in women; in model B, the cut off values used were BMI: 18.5–25 and BF% with cut-offs depending on age: 20–39 years, >19% and >32%; 40–59 years, >21% and 33% and 60–79 years, > 24% and 35% for men and women were used, respectively. Cardiovascular risk estimates were made using QRISK2. SPSS version 18(SPSS Inc. Chicago, IL, USA) was used for all statistical analyses. GraphPad Prism 6 for figures was used. Result Of the 2439 individuals with a normal BMI, 38.5% were found to be in high group and 61.5% were placed in normal weight groups for %BF in model A. In model B, 53.8% and 46.2% were found to be in the normal and high groups for %BF. The odds ratio for the presence of a metabolic abnormality for the high %BF group was 1.82 (95% CI, 1.42–2.34) and for high QRISK was 5.79 (95%CI, 4.17–8.02) after adjusted for age, in model A. In model B, the odds ratio for the presence of a metabolic abnormality for the high %BF group was 2.02 (95% CI, 1.68–2.42) and for high QRISK was 6.03 (95%CI, 4.45–8.08) after adjusted for sex. Conclusion It can be stated that if body fat analysis among normal weight individuals can have an important contribution to the prevention of cardiovascular disease and other obesity-related conditions.

BackgroundThe prevalence of depression increased about 18% during a 10-year period between 2005 and 2015. The aim of the present study was to investigate the association between serum zinc and copper, PAB, SOD and hsCRP in men with depression.MethodsIn this study, 3768 men, were recruited as part of MASHAD study. Demographic, anthropometric and metabolic data measured and recorded for all subjects. The Beck Depression Inventory (BDI) was used for assessing depression in all participants. Serum zinc and copper concentration, hs-CRP, PAB (Pro-oxidant- Antioxidant Balance), and SOD (Superoxide dismutase) were measured in all subjects.Results:The mean level of copper in males with depression is significantly lower than normal males (p 0.05). The median of hs-CRP and mean of PAB were significantly higher in depressed subjects (p Conclusion:Inflammation and copper status, not zinc concentration, are two factors that may play a role in depression in male patients.

Obesity is an important feature of the metabolic syndrome and is associated with an increased risk of type 2 diabetes mellitus, cardiovascular disease, and some cancers. The aim of this study was to determine the relationship between body fat percentage and an imbalance of the prooxidant/antioxidant balance (PAB), serum superoxide dismutase (SOD1) and inflammation (serum hs-CRP) and increase risk of metabolic syndrome and diabetes mellitus. In this study, 9154 individuals were recruited as part of the Mashhad Stroke and Heart Association Disorder (MASHAD) study. Subjects were categorized into two groups according to body fat percentage as defined >25% in male and > 30% in female, according to gender. Biochemical factors, including serum PAB, SOD1, and hs-CRP were measured in all subjects. SPSS version 18 was used for statistical analyses for all. GraphPad Prism 6 for figures was used. Of total number of subjects (9154), 6748 (73.7%) were found to have a high body fat (BF) percentage. Serum hs-CRP and PAB were significantly higher in individuals with a high BF percentage (P 0.05). BF percentage, serum PAB and serum hs-CRP were significantly higher in individuals with metabolic syndrome and diabetes versus those without metabolic syndrome and diabetes mellitus (P < 0.05), however serum SOD1 was significantly lower in individuals with metabolic syndrome (P < 0.005). Oxidative stress and inflammation are two factors that may link the presence of high BF percentage with the development of metabolic syndrome, diabetes, and cardiovascular disease. © 2018 BioFactors, 45(1):35-42, 2019.

Metabolically obese normal weight (MONW) individuals are potentially at increased risk of developing metabolic syndrome. Serum zinc and copper concentrations were assessed in individuals with MONW to determine whether MONW is associated with altered serum zinc and/or copper status. Normal weight subjects (total n = 2419; 1298 men and 1121 women), were recruited as part of Mashhad Stroke and Heart Association Disorder (MASHAD) Study cohort. They were divided into two groups according to the presence or absence of MetS, defined using IDF criteria. Serum zinc and copper concentrations were determined by atomic absorption. Of the 2419 normal weight adults, 377 had MetS. Of this group, 53.7% and 49.7% had a serum zinc 131 µg/dl (Q4) (p = 0.034), and 18.8% had a serum zinc >95 µg/dl (Q4). Logistic regression analysis was performed to determine the odds ratio (OR) for an association of serum zinc, copper and zinc to copper ratio with MetS in normal weight subjects. The subjects with a serum zinc >95 µg/dl (Q4) had 0.386 [OR: 0.614(95%CI 0.457–0.823)] lower chance of MetS (p = 0.001) and the subjects with a serum copper >131 (Q4) had OR 1.423 (95% CI: 1.09–1.857) higher chance of MetS (p = 0.009). These data remained significant after adjustment for age and sex, for serum zinc and copper, respectively. Furthermore, our results strongly suggested that zinc and copper were the independent risk factor for metabolic syndrome in normal weight subjects. There is an imbalance between serum copper and zinc concentrations among individuals with MONW when compared with normal BMI individuals without MetS. This may increase the risk of individuals with MONW developing conditions associated with this imbalance, such as diabetes and cardiovascular disease.

Depression and Anxiety are two important public health problems that are known to be associated with viral infections. The association between the intake of nutrients such as zinc and copper with symptoms of depression has been studied previously. The aim of the current study was to investigate the association between depression with human T cell lymphotropic virus type 1 (HTLV-1) infection and serum content of zinc and copper in a large Iranian population cohort. The study population consisted of 279 HTLV-1-positive patients who were identified after recruitment as part of a large cohort study: the Mashhad Stroke and Heart Association Disorder (MASHAD) study. They were divided into two groups of diagnosed with or without depression based on their symptoms. Serum zinc and copper levels of all subjects were measured using the flame atomic absorption spectrometry. The population sample comprised of 279 individuals infected with HTLV-1 of whom 192 (68.8%) were women. The mean serum zinc in the group with and without depression was 78.69 ± 13.79 μg/dl and 86.87 ± 19.44 μg/dl, respectively (p

The prevalence of hypertension (HTN) is increasing globally. It has been shown that there is an association between micronutrient deficiency and HTN. In the current study, we aimed to assess the association between HTN with serum copper and zinc concentrations in a large representative Iranian population. The participants were enrolled into the Mashhad stroke and heart atherosclerotic disorders study (MASHAD study), a cohort study that was initiated in 2010. Anthropometric indices were assessed using standard procedures. Systolic (SBP) and diastolic (DBP) blood pressures were measured using a standard mercury sphygmomanometer. Fasting blood glucose (FBG), lipid profile, uric acid and blood urea nitrogen (BUN), and hs-CRP were measured using routine methods. HTN defined as persons who had SBP ≥ 130 mmHg and/or DBP ≥ 85 mmHg and/or medication use. Flame atomic absorption (Varian AA240FS) was used to measure serum Zn and Cu concentrations. SPSS software was used for all statistical analyses. A total of 9588 participants were recruited into the MASHAD study project. Participants were divided into two groups; 5695 healthy (non-hypertensive) (mean age 45.85 ± 7.5 years) and 3893 hypertensive participants (mean age 51.18 ± 7.67 years). Systolic (p 0.001) and diastolic blood pressure (p 0.001) were significantly different for different serum copper quartiles. The participants with serum copper levels 80 μg/dl had 1.33 times greater risk of an increased blood pressure than other participants. Participants with serum copper levels 130 μg/dl had a 1.94-fold higher risk of raised blood pressure. Serum zinc was not associated with systolic blood pressure, but individuals in the first quartile level of serum zinc had a diastolic blood pressure that was significantly higher than other quartiles (p = 0.035). Serum copper is associated with blood pressure status in adults in a U-shaped relationship, with a range of serum copper between 80 and 130 μg/dl being associated with normal blood pressure.
