The relationship between serum lipid profile and selected trace elements for adult men in mosul city.

ABSTRACT: OBJECTIVES: To evaluate the correlations of the serum concentrations of copper, zinc, and manganese with lipid profile parameters of adult men in Mosul City, Iraq. METHODS: The study included 51 apparently healthy adult men as a control group aged 34-62 years (group 1), and 31 hyperlipidemic patients aged 37-60 years (group 2). Trace elements copper, zinc and manganese were determined using atomic absorption spectrometry. Concentrations of total cholesterol, triglyceride and high density lipoprotein cholesterol were determined using enzymatic method. Indirect serum concentration of low-density lipoprotein cholesterol were calculated via the Friedewald formula. Data were evaluated as mean and standard deviation by analysis of variance (ANOVA) and t-test. RESULTS: The results indicated that there is a significant lower level of serum zinc in hyperlipidemic patients compared with the control group, while copper and manganese showed no significant differences between the two groups. A significant negative correlation was found between serum zinc and total cholesterol, low-density lipoprotein cholesterol, triglyceride and low/high-density lipoprotein cholesterol ratio; while a significant positive correlation was found between serum zinc and high density lipoprotein cholesterol. In addition, a significant positive correlation between copper and triglyceride existed in the patient group, while the control group showed no such correlation. CONCLUSION: Hyperlipidemia may possibly be related to a decrease in the level of serum zinc in hyperlipidemic adult men. The data also supports the concept that zinc supplementation might be useful in improving metabolic complications in subjects with hyperlipidemia.

Project description:The prevalence of obesity has increased at an alarming rate worldwide. Metallic elements are involved in the pathogenesis of obesity and related diseases. To date, whether environmental exposure to metallic elements has effects on obesity in children and adolescents is still unclear. The aim of the current study was to investigate the association of blood metallic elements with obesity in U.S. children and adolescents. This cross-sectional study was performed with 5404 children and adolescents (6-19 years, 2745 males and 2659 females) who participated in the US National Health and Nutrition Examination Survey 2011-2014. Blood lead, mercury, selenium, manganese, copper, and zinc, as well as biochemical parameters including triglyceride (TG), cholesterol, low-density lipoprotein (LDL), and homeostasis model assessment of insulin resistance (HOMA-IR) were assessed for all subjects. Multivariate logistic regression and linear regression were applied to assess associations of metallic elements and overweight, obesity status, and serum metabolites as distinct outcomes adjusted for age, gender, ethnicity, and the poverty income ratio. When stratified by age and sex, significant associations were found between the highest quartile of copper concentrations in blood with obesity status (OR = 9.27, 95% CI: 5.43, 15.82, pfor trend < 0.001) and cholesterol (OR = 3.08, 95% CI: 1.43, 6.63, pfor trend < 0.001). The highest concentrations of manganese in the blood was associated with obesity in those aged 6-19 years (OR = 2.29, 95% CI: 1.74, 3.02, pfor trend < 0.001). Moreover, blood mercury and selenium showed positive relationships with cholesterol. Further, a negative association existed between blood zinc and obesity. The National Health and Nutrition Examination Survey data provide epidemiological evidence that blood metallic elements are positively associated with obesity in children and adolescents. However, the underlying mechanisms still need further exploration.

Project description:Aquaculture contributes to the global animal protein supply and the prevention of malnutrition and diet-related diseases (FAO (Food and Agriculture Organization of the United Nations); Fiorella et al., 2021). In particular, fish is a significant source of animal protein, fatty acids (e.g., docosahexaenoic acid, eicosapentaenoic acid), vitamins, and essential trace elements in the human diet. Nonetheless, fish bioaccumulates metals from their diet and habitat. This data article includes information on the concentrations of 4 essential and 4 non-essential trace elements in cultured rainbow trout (Oncorhynchus mykiss) and the human health risks through fish consumption in the adult population. Concentrations of four essential (Cr, Cu, Ni, and Zn) and four non-essential (As, Cd, Pb, and Hg) elements were quantified in ninety-one O. mykiss samples from an in-door production system. Total mercury (THg) levels in samples were determined by AAS, and other analyzed trace elements were measured by ICP-OES after microwave-assisted acid digestion. The highest concentrations of metals/metalloid (mg/kg wet weight) in fish muscle were Cr (0.44), Cu (4.21), Ni (1.01), As (0.47), Cd (0.045), Pb (0.65), THg (0.029), and Zn (6.21). The average concentrations of Cr and Pb exceeded their respective maximum limit. In most cases, median metal concentrations significantly (p < 0.05) differed across the fish size groups (small: 264-295 mm; medium: 300-395 mm; and large: 400-552 mm). The median concentrations of Cd, Zn, and THg in the large size group differed significantly (p < 0.05) between genders. The estimated weekly intake values of quantified elements from muscle were below the provisional tolerable weekly intakes. Non-carcinogenic risk assessment in adult consumers, being below one (THQ ≤ 1; and TTHQ ≤ 1), indicated an insignificant health hazard. The estimated incremental and cumulative cancer risks in the adult class through Cr, As, Ni, and Pb exposure were greater than the benchmark (10-5). Accordingly, high dietary intake of metals/metalloid from cultured O. mykiss posed a risk of carcinogenesis in the adult risk class.
