Abstract
Alcohol abuse is a well-known cause of imbalance in trace element levels and oxidant/antioxidant status of individuals with long time consumption. However, the levels of these parameters in the patients on the early stages of alcohol dependence without liver damage differ on various studies. The aim of our study was to measure the levels of trace elements in the serum and oxidative/antioxidative system members in the red blood cells (RBC) of early-stage alcoholic individuals and compare with control subjects. Our study included 21 male patients recently hospitalized for alcohol abuse and 25 healthy non-abusing male controls. Levels of Fe, Zn, and Cu in the serum and MDA, SOD, CAT, and GSH in the red blood cells (RBC) of the subjects were measured. Fe, Zn, and Cu levels were lower in the study group when compared to the controls. Levels of lipid peroxidation marker MDA was high, whereas the activities of antioxidant enzymes SOD and CAT were decreased in our study group. However, levels of GSH, an antioxidant compound were higher in the alcohol abuse group. RBC SOD levels were positively correlated with Fe, Cu, Zn, and CAT. There was a positive correlation between Fe-Cu, Zn-Fe, Zn-Cu, CAT-Zn, and CAT-SOD. MDA was negatively correlated with Fe, Zn, SOD, and CAT. The results obtained from present study indicate that high levels of alcohol intake are related with increased oxidative damage and decreased levels of antioxidant enzymes and trace elements. Additionally, antioxidant compensation mechanisms are still on process in the early stages of chronic alcohol exposure.

Abstract
The aim of this study was to monitor the circulating and salivary ion concentrations by total reflection X-ray fluorescence (TXRF) in futsal players submitted to the futsal-specific intermittent shuttle protocol (FISP). TXRF may allow identification of changes in ion concentrations induced by physical efforts. Saliva and blood samples of 13 male futsal players were collected before (Pre) and after (Post) the FISP. Salivary and plasma ion levels were detected by TXRF, and differences from Pre to Post (paired t test or Wilcoxon test) and correlations between both biological fluids were determined (P < 0.05). All saliva samples presented phosphorus (P), sulfur (S), chlorine (Cl), potassium (K), calcium (Ca), iron (Fe), zinc (Zn), bromine (Br), and rubidium (Rb). S, Cl, Ca, Fe, Cu, Zn, Br, and Rb were detected in all blood samples. K, Cu, Br, and Rb presented reduced secretion rate from Pre to Post samples (P < 0.05). The salivary concentrations of K (r = - 0.53) and Zn (r = 0.54) were correlated with plasmatic concentrations. After FISP, salivary secretion of S (r = - 0.76), Cl (r = - 0.64), P (r = - 0.67), Mn (r = - 0.74), and Zn (r = 0.69) were correlated with plasma levels. We concluded that TXRF may be used to monitor salivary (P, S, Cl, K, Ca, Fe, Zn, Br, and Rb) and circulating (S, Cl, Ca, Fe, Cu, Zn, Br, and Rb) levels of several elements in futsal athletes. However, an acute bout of futsal-specific physical effort did not significantly imbalance ion concentrations in saliva or plasma.

Abstract
The aim of the present study was to investigate hair essential trace elements and mineral levels in 105 pregnant normal-weight (control) and 55 overweight and obese women in the third trimester of pregnancy, as well as in their children at the age of 9 months. The hair essential trace elements and mineral levels were assessed using inductively coupled plasma mass-spectrometry. Overweight pregnant women had significantly reduced Cr (- 24%; p = 0.047) and Zn (- 13%; p = 0.008) content, as well as elevated hair Na and K levels as compared to the controls. Children from overweight and obese mothers had lower hair Mo (- 18%; p = 0.017), Se (- 8%; p = 0.043), and V (- 24%; p = 0.028) levels, as well as elevated Sr content (19%; p = 0.025). Correlation analysis revealed a significant relationship between maternal and child hair levels of Co (r = 0.170; p = 0.038), Cu (r = 0.513; p < 0.001), Mn (r = 0.240; p = 0.003), and Na (r = 0.181; p = 0.027) in the whole sample. Pre-pregnancy maternal body mass index (BMI) positively correlated with maternal hair K (r = 0.336; p < 0.001) and Na (r = 0.212; p = 0.008) and negatively correlated with V (r = - 0.204; p = 0.011) and Zn (r = - 0.162; p = 0.045) levels. The results indicate that impaired trace element and mineral metabolism may play a role in the link between maternal obesity, complications of pregnancy and child's postnatal development. Hypothetically, dietary improvement may be used as a tool to reduce these risks. However, further experimental and clinical studies are required to investigate the relationship between obesity and trace element metabolism in pregnancy.

Abstract
Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease of multifactorial origin. Studies have shown that trace elements such as zinc and copper may help maintain optimum function of the immune system and metabolism, while toxic metals such as lead may increase systemic autoimmunity. The current study aimed to assess the relationship between serum concentration of lithium (Li), vanadium (V), copper (Cu), zinc (Zn), molybdenum (Mo), cadmium (Cd), and lead (Pb) and SLE diagnosis, disease activity measured by SLE disease activity index (SLEDAI) and insulin resistance (IR). This case-control, cross-sectional study included 225 patients, 120 healthy controls, and 105 SLE patients. Serum concentration of Li, V, Cu, Zn, Mo, Cd, and Pb was measured. Serum concentrations of V (p < 0.001), Zn (p < 0.001), and Pb (p < 0.001) were lower and Mo (p < 0.001) and Li (p < 0.001) were higher in patients with SLE compared to healthy controls. SLE diagnosis was associated with higher serum Li (p < 0.001) concentration and lower V (p < 0.001), Zn (p = 0.003), and Pb (p = 0.020). Toxic metals and trace elements were not associated with disease activity. Levels of Cd were higher in patients with IR (p = 0.042). There was no significant association between IR and the other metals. The results indicate that SLE patients have different profiles of trace elements and toxic metals compared to healthy controls. While some toxic metals and trace elements were found to be associated with SLE diagnosis, they had no effect on disease activity and IR.

Abstract
INTRODUCTION Though micronutrient formulations for parenteral nutrition (PN) have been revised, the impacts of these changes on nutritional parameters, blood micronutrient levels, and safety have yet to be clarified. We examined the efficacy and safety of a new PN formulation with a micronutrient composition based on the Food and Drug Administration 2000 recommendation in surgical patients. METHODS This phase III clinical trial (JapicCTI-No. 142610) was a prospective, randomized, controlled, parallel-group, open-label, multicenter study. Two types of PN, OPF-108 (revised formula, n = 51) and ELN (previous formula mainly based on American Medical Association 1975 guidelines, n = 59), were given to patients from POD1 or 2 to POD7 after surgery. OPF-108 contains more vitamin B1, B6, C, and folic acid, a much lower dose of vitamin K, and less iron than ELN. Nutritional parameters and micronutrient profiles in blood and safety were evaluated. RESULTS Nutritional parameters on POD5 and 8 were similar between the 2 groups. Blood vitamin B1, B6, and folic acid levels on POD 5 and 8 were higher in the OPF-108 group than in the ELN group. Only OPF-108 restored vitamin C levels to within the normal range on POD5 and 8. Vitamin K levels far exceeded the upper limit of the standard range on POD5 and 8 in the ELN group, whereas OPF-108 essentially maintained these levels within the standard ranges. Serum iron levels on POD8 were nearly normal in both the OPF-108 and ELN groups. CONCLUSION Beneficial effects of the new micronutrient formulation were demonstrated in surgical patients.

Abstract
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 < 0.001). Also, the serum copper level was higher in the depressive group (116.75 ± 39.56) than in the non-depressive group (104.76 ± 30.77) (p 0.004). The association between serum zinc and copper with depression in HTLV-1-infected patients which was shown in this study could be considered in the treatment strategies in these patients.
