Cystic fibrosis (CF) patients require a stable and sufficient supply of micronutrients. Since copper is an essential micronutrient for human development, a cross-sectional study was carried out to investigate the serum copper levels, serum copper/zinc (Cu/Zn) ratios, and their relationship with nutritional indicators in a group of CF patients. Anthropometric, biochemical, and dietary measurements, an abdominal ultrasound, and respiratory and pancreatic tests were conducted. Seventeen CF patients were studied (10 females, 59%), 76.5% of whom were ∆F580. Their mean serum copper (113 ± 23 μg/dL) was normal, and there was only one teenager with hypocupremia (6%) and two children with hypercupremia (18%). A significant association between serum copper and zinc levels was discovered. The Cu/Zn ratio was higher than 1.00 for 94% of patients, which is an indicator of an inflammation status. There was no significant correlation between the serum copper concentrations and respiratory and pancreatic function, respiratory colonization, and the results of the abdominal ultrasound. Linear regression analysis showed that serum copper had a positive association with both the Z-score body mass index (BMI) and mean bone conduction speed (BCS). Therefore, since 94% of CF patients had a Cu/Zn ratio > 1.00, this factor must alert us to consider the risk of zinc deficiency and high inflammatory response. The measurement of serum zinc alone does not show one’s zinc status. However, the Cu/Zn ratio may be an indicator of zinc deficiency and the inflammatory status of CF patients.

Background: This study aims to determine and compare the levels of trace elements copper, zinc, selenium and chromium in GCF and serum of patients with periodontitis and healthy individuals. Methods: This cross sectional study includes 24 study subjects recruited from the patients reporting to the Department of Periodontics , Tagore Dental College Chennai. All the selected patients were subjected to a clinical examination done by a single examiner. The estimation of trace elements Copper, Zinc, Selenium and Chromium in GCF and serum is performed using Perkin Elmer optima 5300 Inductively Coupled Plasma Emission Spectrometer (ICPOES). Results: GCF and serum copper levels showed no significant difference in both periodontitis and healthy groups . Selenium levels tend to be the same in both groups. Serum zinc levels are more in periodontitis patients than healthy subjects (p less than 0.01). GCF chromium levels are found to be more in patients with periodontitis than healthy. Conclusions : More research is therefore needed to monitor the role of these trace elements C with an increased sample size to ascertain whether they are associated with a reduced risk of periodontitis.

Cirrhosis Of Liver

Cirrhosis of liver is one of the common medical problem in daily clinical practice and one of the leading causes of morbidity and mortality. Zinc is an essential trace elements for human and plays in many biological roles in the body. Among them, zinc deficiency is thought to be involved in metabolism of ammonia and causes hyperammonia that worsen hepatic encephalopathy. This study aimed to find out the severity of cirrhosis of liver was by Child Turcotte Pugh score and to investigate the associations between serum zinc level and severity of cirrhosis. A hospital-based cross-sectional descriptive study was performed on 78 patients with different underlying causes of cirrhosis of liver at the Medical Units of Yangon General Hospital and Yangon Specialty Hospital. Among the study population, Child grade A was found to be 28.21%, Child grade B was 30.77% and Child grade C was 41.03%. Regarding result of serum zinc level, 62.8% were low level, 28.2% were within normal level and 8.9% were high level. Mean value of serum zinc level in grade A was 0.68 mg/l, grade B was 0.54 mg/l and grade C was 0.48 mg/l (p=0.00). It was found out that there was a high prevalence of zinc deficiency in severe cirrhotic patients. The zinc level was significantly lowest among patients with Child-Pugh C as compare to those with Child-Pugh B and C. Severity of zinc deficiency should be requested for supplementation therapy in cirrhotic patients as to prevent complications such as hepatic encephalopathy, hepatocellular carcinoma and liver failure. Screening for zinc deficiency may need in these patients with more advanced cirrhosis because it seems to be a marker of advanced liver disease and it can be deducted that awareness of serum zinc level among cirrhotic patients is very important in clinical practice.

The Mean

This cross-sectional study assessed the risk of zinc deficiency in randomly selected children, aged between 7 and 11 years, living in a poor, peri-urban informal settlement in South Africa. Dietary intake of 149 respondents was evaluated by 24-hour recall and quantitative food frequency questionnaires. Anthropometric and biochemical indices of a subset of 113 were determined. Descriptive statistics, analysis of variance and Pearson correlations were computed using the Statistical Package for Social Sciences, version 14.0. Anthropometric data were analysed using the World Health Organization Anthro plus version 1.0.2 statistical software. Dietary data were analysed with FoodFinder® version 3. The mean age of the children was 9.0±1.1 years. Few zinc-rich sources appeared in the diet that was predominantly plant-based. Mean dietary zinc intake was 4.6±2.2 mg/day. The mean value of serum zinc was 66.4±21.5 µg/dL, with 46% of the children having values less than the 70 µg/dL cut-off. The findings indicate a high risk of zinc deficiency and suboptimal zinc status for the majority of this study population of children, possibly as a result of low consumption of food sources with high bioavailability of zinc, which invariably is a direct consequence of poverty and food insecurity.OpsommingDie doel van hierdie dwarsdeursnitstudie was die bepaling van die risiko van ’n sinktekort in ’n ewekansige steekproef van 7 tot 11 jaar-oue kinders, woonagtig in ’n arm, voorstedelike informele woonbuurt in Suid Afrika. Dieetinnames van 149 respondente is geëvalueer deur 24-uur herroep en kwantitatiewe voedselfrekwensie vraelyste. Antropometriese en biochemiese indikatore van ’n kleiner steekproef van 113 is ook bepaal. Beskrywende statistiek, analise van variansie en Pearsonkorrelasies is bepaal deur die Statistical Package for Social Sciences, uitgawe 14.0. Antropometriese data is geanaliseer deur die statistiese program, Anthro plus, uitgawe 1.0.2, van die Wêreld Gesondheid Organisasie. Dieetdata is met behulp van FoodFinder® uitgawe 3 geanaliseer. Die gemiddelde ouderdom van die kinders was 9.0±1.1 jaar. Min sinkryke voedselbronne is in die hoofsaaklik plantryke dieet waargeneem. Die gemiddelde sinkinname was 4.6±2.2 mg/dag en die gemiddelde serumsinkwaarde was 66.4±21.5 µg/dL, met 46% van die kinders se waardes onder die 70 µg/dL afsnypunt. Die bevindings dui op ’n hoë risiko vir sinktekort en suboptimale sinkstatus vir die meerderheid van hierdie kinders, moontlik as gevolg van die swak inname van voedselbronne met hoë biobeskikbare sink, wat gewoonlik ’n direkte gevolg van armoede en huishoudelike voedsel insekuriteit is.

Abstract 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); despite the lower level of zinc in depressed subjects, this was not significant (p > 0.05). The median of hs-CRP and mean of PAB were significantly higher in depressed subjects (p < 0.001). Logistic regression analysis was performed to determine the odds ratio (OR) for an association of serum zinc, copper, hs-CRP, SOD and PAB with depression in males. The subjects with a serum copper < 80 µg/dl (Q1) had a 1.337 (1.13–1.582) higher chance of depression and the chance of depression increased 1.021(1.013–1.029) with elevating 1 mg/l of serum hs-CRP. 1.021(1.013–1.029). These data remained the same after adjustment for each other’s. Furthermore, our results strongly suggested that hs-CRP and copper were the independent risk factors for depression in male patients.Conclusion:Inflammation and copper status, not zinc concentration, are two factors that may play a role in depression in male patients.

Background: Transfusion dependent thalassemia (TDT) patients require regular blood transfusion and iron chelator therapy to maintain their life. Iron chelator may alter serum zinc and copper level in TDT patients. Objective: To observe serum zinc and copper and ferritin levels in transfusion dependent thalassemic patients treated with iron chelator. Method: The present cross sectional study was carried out in the department of Physiology, BSMMU, Dhaka between September 2017 to February 2019. Thirty cases of TDT, aged 5-40 year were included in the study group. Age and sex matched 30 healthy subjects were also studied as control. All the TDT patients were selected from the outpatient Department of Hematology and Transfusion Medicine, BSMMU, Dhaka. Serum zinc was measured by Spectrophotometric method and serum copper and ferritin levels were measured by colorimetric method. For statistical analysis independent sample t test was used. Result: The mean serum zinc level was significantly (p<0.05) lower and serum ferritin level was significantly (p<0.001) higher in TDT compared to control. Again, mean serum copper level and Zn/Cu ratio were not significantly (p>0.05) different in study groups compared to that of control. In addition, 3.3 % TDT patients had hypozincemia and 13.3% TDT patients had hypercupremia. Conclusion: This study may conclude that low serum zinc level and high copper level may be associated with TDT patients treated by combined deferoxamine (DFO) & deferiprone (DFP) iron chelator.

Abstract Background: Cystic fibrosis (CF) lung disease is associated with chronic inflammation leading to progress in lung function. Adiponectin is a predominantly anti-inflammatory adipokine that may have a role in CF lung. This study aims to determine total sputum and total plasma adiponectin levels in clinically stable adults CF patients with CFTR I1234V mutation, compared to plasma adiponectin levels in healthy controls and to investigate their correlations with body mass index (BMI) and spirometry in patients with CF. Methods: A cross-sectional study comprises 17 CF patients and 18 healthy controls. Adiponectin levels were measured by magnetic bead-based multiplex assay. Results: The mean age of adult CF patients was 22.9 years± 3.8 (18-30) and 76.5% CF patients had pancreatic sufficiency. The mean BMI in healthy controls was slightly higher than CF patients. The mean sputum adiponectin level was significantly lower than plasma adiponectin levels in CF patients and healthy controls (p<0.001), whereas no significant difference in plasma adiponectin levels between CF patients and healthy controls. The mean sputum adiponectin level was observed to be higher in CF patients with pancreatic insufficiency. Sputum adiponectin level was correlated positively with plasma adiponectin level in CF patients (r= 0.47, p=0.06). Sputum and plasma adiponectin levels in CF patients were correlated negatively with BMI and percentage predicted forced expiratory volume in 1 second (FEV1) and Forced vital capacity (FVC). Conclusions: Sputum adiponectin may provide a minimally invasive tool in the assessment of an inflammatory status in CF patients. Further larger study to address any difference in sputum and plasma adiponectin levels among CF patients with pancreatic sufficiency versus pancreatic insufficiency.

Abstract.Objective: This study aimed firstly to assess zinc and iron status of 9–12-year-old children of Tehran and secondly to determine a cut-off for circulating biomarkers of iron status to identify children at increased risk of zinc deficiency. Research methods & procedures: In a cross-sectional study, demographic and anthropometric data from 505 boys and 467 girls aged 9–12 years from Tehran primary schools were obtained and their zinc and iron status was assessed. Results: The prevalence of zinc deficiency, anemia, and iron depletion was 12.4, 14.6, and 9.5%, respectively. Serum zinc con-centration was significantly lower in children with anemia than in their non-anemic peers (p < 0.05). There was no significant association between zinc and iron status and serum high sensitivity C-reactive protein. Zinc-deficient children, compared to those with normal serum zinc, had significantly shorter stature (139.7 (±6.9) vs 141.3 (±7.1) cm, CI: -2.97 – -0.2, p = 0.029). Serum zinc concentration was the predictor of height in the children (p = 0.004, CI: 0.01 – 0.054). A logistic regression model showed an increased risk of low serum zinc and ferritin in children who resided in economically poor regions (OR = 1.65, p = 0.043; OR = 1.92, p = 0.016, respectively). Using ROC curve and Youden index, the optimal cut-off value for serum ferritin to indicate zinc deficiency was 14.9 µg/L (sensitivity = 90%, specificity = 61%). Conclusions: Lowered zinc and iron status among the children in deprived regions is likely to be due to poor quality of diet. Moreover, children with serum ferritin lower than 14.9 µg/L must be carefully assessed for concomitant zinc deficiency.

Trace minerals are required by the body in minute quantities ranging from as little microgram to milligram per day. The trace elements known to be essential for humans and unquestionably associated with deficiency system.  Zinc is a component of all cells; it is needed for the growth and repair of tissues and is a cofactor for at least 70 different enzymes (Baumgartner, 1993). There is experimental evidences for zinc deficiency as a teratogenic agent and in humans the high rates of neural tube defects (NTD) in some regions where zinc deficiency is common (Hurley, 1981; Sever, 1989).  In animals zinc deficiency has been shown to cause central nervous system defects (Keen and Hurley, 1989). It is well known that there are interactions between zinc and other trace minerals.  Normal levels of these and good relation between them are factors conditioning human health (Janicki, 1991). The present study aims at assessing blood, serum zinc, copper and manganese levels and zinc/copper, zinc/manganese ratios of mother and their babies having NTD.DOI: http://dx.doi.org/10.3126/on.v9i1.5749

AbstractBackground and Aims: In Nigeria, community-based epidemiological data related to the prevalence of zinc deficiency in preschool children are scarce. We assessed the prevalence of zinc deficiency and the associated socio-demographic variables in children aged between 6 and 60 months, living in a Nigerian rural community.Materials and Methods: In this cross-sectional study, the serum zinc concentrations of 252 children aged between 6 and 60 months in a rural community in Nigeria were assessed, using atomic absorption spectrophotometry. The study population was selected by multistage random sampling and at least two children were selected from every household which had children in the study age group. The socio-demographic characteristics of the subjects were obtained, using an interviewer-administered questionnaire.Results: A total of 252 children were studied, 134 (53.2%) males and 118 (46.8%) females. The mean age was 32.7±17.0 months, similar for both sexes. Overall, 220 (87.3%) had low serum zinc concentrations (less than 7.65µmol/L). According to age, the highest mean serum zinc concentration was 5.43±3.52µmol/L in children aged between 6 and 12 months. Correlation between serum zinc concentration and family size or socio-economic status (SES) showed that the smaller the family size and the higher the SES, the higher the serum zinc concentration.Conclusions: The high prevalence of low serum zinc concentration indicates that zinc deficiency is a public health problem in our rural communities, requiring public health intervention.
