The Assessment of Neonatal Anthropometric Indices Association with Umbilical Cord Blood Zinc and Magnesium Levels.

The present research aims to find the association between neonatal anthropometric parameters and zinc and magnesium concentration in cord blood. The current cross-sectional report is a sub-study from the "PERSIAN Birth Cohort Study" conducted on 112 pairs of mother-neonate referring to the index hospitals for giving birth to their children during 2018-19. Umbilical cord blood was collected at delivery for the measurement of zinc and magnesium. Anthropometric indices were measured in standard protocols. Validated questionnaires were used for maternal diet in different trimesters. Dietary patterns were acquired based on exploratory factor analysis. The birth weight was reversely correlated with zinc concentration (r = -0.249, P-value = 0.008); however, the other anthropometric parameters did not show any association with zinc levels (P-value > 0.05). Similar evaluations for magnesium revealed no association between any of the anthropometric indices and this micronutrient agent (P-value > 0.05). Further evaluations represented insignificant differences in both zinc (P-value = 0.51) and magnesium levels (P-value = 0.49) between those with normal versus low birth weight. There was a negative association between the Western dietary pattern in the first trimester of pregnancy and cord blood zinc concentration (β (SE) = -0.21 (0.10); P = 0.026); while healthy and traditional dietary patterns in second and third trimesters were positively related to cord zinc concentration (all P < 0.05). This research did not document a positive statistical association of cord blood zinc and magnesium with birth weight. The association of maternal Western dietary patterns with lower cord blood zinc levels highlights the importance of healthy nutritional habits in pregnancy.

Acupuncture at Sifeng (EX-UE 10) for pediatric anorexia: A systematic review and meta-analysis

ObjectiveThe purpose of this study was to assess the efficacy and safety of acupuncture at Sifeng for pediatric anorexia. MethodsThe randomized controlled trials (RCTs) of acupuncture at Sifeng for pediatric anorexia from their beginning to October 2022 were looked up in the seven databases. The Cochrane risk of bias evaluation tool was applied to the risk of bias analysis of the included studies. A meta-analysis of the total efficiency, score of food intake reduction, time to normalize food intake, body weight, leptin levels, and blood zinc levels was performed using Review Manager 5.3 software. The GRADE criteria were applied to assess the evidence's quality. ResultsA total of 24 RCTs were included, involving 2202 children. The allocation of concealment, blinding, and selective reporting has a high or unclear risk of bias. All experiments compared acupuncture at Sifeng with traditional Chinese medicine or Western medicine. The results showed that, compared with medicine, acupuncture at Sifeng could significantly improve the total efficiency (OR=6.44, 95%CI [4.78,8.66]), lower the score of food intake reduction (MD=−0.69, 95%CI [−1.00, −0.39]), decrease leptin levels (MD=−5.19, 95%CI [−8.09, −2.29]) and time to normal food intake (MD=−2.22, 95%CI [−2.42, −2.01]), increase blood zinc (MD=0.79, 95%CI [0.21, 1.37]) and body weight (MD=1.28, 95%CI [0.85, 1.72]). Seven studies found that the treatment was safe both during and after. Based on the GRADE criteria, the quality of the evidence for the majority of indicators was extremely poor. ConclusionThe low certainty of evidence suggested that acupuncture at Sifeng was effective and safe in the therapy of pediatric anorexia. Future high-quality clinical studies are needed to provide more reliable evidence of the effectiveness and safety of the therapy.

Multi-element Exposure and Cognitive Function in Rural Elderly Chinese.

To investigate the relationship between selenium (Se) based multi-element combined exposure and cognitive function in rural elderly individuals, a cross-sectional study was conducted. The study involved 416 older adults aged 60 and above, residing in four different areas of Enshi county, China, with varying soil Se levels. Inductively coupled plasma mass spectrometry (ICP-MS) was employed to measure the concentrations of Se, copper (Cu), iron (Fe), zinc (Zn), calcium (Ca), magnesium (Mg), cadmium (Cd), arsenic (As), and lead (Pb) in whole blood. Nine standard cognitive tests were applied to assess cognitive function. Analysis of the least absolute shrinkage and selection operator regression (LASSO), covariance (ANCOVA), and generalized linear model (GLM) were utilized to investigate the relationship between element exposure and cognitive function. The results of LASSO revealed that Se, Cu, Fe, Zn, Ca, and Pb were independently identified to be associated with cognition. Both ANCOVA and GLM demonstrated that Se and Ca were correlated with cognitive function. The multi-element model showed higher composite Z scores of 0.32 (95% CI: 0.09 to 0.55) for log-transformed Se (P = 0.007), 0.75 (95% CI: 0.01 to 1.49) for log-transformed Cu (P = 0.048), and a lower score of - 0.67 (95% CI: - 1.26 to - 0.08) for log-transformed Ca (P = 0.025). Furthermore, there was evidence that Se could counteract the negative impact of Ca on cognitive function (P for interaction = 0.031). Our findings suggested that higher levels of Se and Cu were associated with better cognitive function in the elderly and Se can counteract the cognitive damage caused by Ca.

Urea molasses mineral block under various feeding systems improved nutrient digestibility, productive performance and blood biochemical profile of Yaks

BackgroundThe study aimed to investigate the effect of urea molasses mineral blocks (UMMB) on nutrient digestibility, productive performance and blood biochemical profile of indigenous yaks under various feeding systems. A total of sixteen yaks were randomly divided into four groups (n = 4 animal per group) and offered the, following feeding systems: (A) stall feeding, (B), urea molasses mineral block (UMMB) + stall feeding, (C) yard feeding and (D) UMMB + yard feeding. Trial lasted for 40 days.ResultsResults showed that nutrients intake (g) and nutrient digestibility (%) of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE) and crude fiber (CF) were significantly higher (p < 0.05) in stall and yard feeding groups with UMMB licking. Blood zinc, cobalt, hemoglobin (Hb), red blood cell (RBC), glucose and serum glutamate private transaminase (SGPT) significantly (p < 0.05) increased in stall and yard feeding with UMMB licking. Milk yield, Ca and monounsaturated fatty acid except milk composition improved significantly (p < 0.05) in stall and yard feeding groups with UMMB licking.ConclusionIt was concluded that feeding of UMMB improved utilization of low-quality roughages and best results were obtained from stall and yard feedings with UMMB licking as compared to other groups.

The Role of Non-genetic Therapies to Reduce the Incidence of Sickle Cell Crisis: A Systematic Review.

Sickle cell anemia is a hemoglobinopathy that causes complications such as Vaso-Occlusive Crisis (VOC), stroke, priapism, Acute Chest Syndromes (ACS), and bone infarcts due to blood vessel occlusion, resulting in hypoxia, ischemia, and inflammation. Preventing these incidents improves the quality of life and lowers mortality rates in Sickle Cell Disease (SCD) patients. This systematic review aims to describe the drugs, their mechanisms of action, dosages, changes in hemoglobin parameters, decrease in VOCs, delay the time for the next VOC, decrease in the length of hospital stay, and side effects associated with these drugs. This review adheres to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020 guidelines. For this review, we searched the PubMed, Google Scholar, and Cochrane databases and screened them for full free texts published in English and studied in humans in the last five years beginning in 2018. Randomized clinical trials (RCT), observational studies, meta-analyses, systemic reviews, and traditional reviews were all included in the search. According to the type of study, quality assessment tools are used, and eight papers are chosen. Full-text articles from these papers are studied, analyzed, and tabulated. We discussed seven interventions that are used to treat sickle cell disease. Voxelotor, crizanlizumab, L-glutamate, long-term blood transfusions, Zinc (Zn), Niprisan®, and Ciklavit* were found to reduce the number and severity of VOC. We discovered that VOCs containing L -glutamate reduced the length of hospitalization. Magnesium (Mg) did not affect the number and severity of VOCs. This review includes a few articles for the study. Future papers on this subject should include a large sample size and many papers. More clinical trials are required to evaluate the dosages and outcomes of using these drugs in combination to prevent VOCs.

The Blood Concentration of Metallic Nanoparticles Is Related to Cognitive Performance in People with Multiple Sclerosis: An Exploratory Analysis.

The imbalance in the concentration of metallic nanoparticles has been demonstrated to play an important role in multiple sclerosis (MS), which may impact cognition. Biomarkers are needed to provide insights into the pathogenesis and diagnosis of MS. They can be used to gain a better understanding of cognitive decline in people with MS (pwMS). In this study, we investigated the relationship between the blood concentration of metallic nanoparticles (blood nanoparticles) and cognitive performance in pwMS. First, four mL blood samples, clinical characteristics, and cognitive performance were obtained from 21 pwMS. All participants had relapse-remitting MS, with a score of ≤4.5 points in the expanded disability status scale. They were relapse-free in the three previous months from the day of collection and had no orthopedic, muscular, cardiac, and cerebellar diseases. We quantified the following metallic nanoparticles: aluminum, chromium, copper, iron, magnesium, nickel, zinc, and total concentration. Cognitive performance was measured by mini-mental state examination (MMSE) and the symbol digit modalities test (SDMT). Pearson's and Spearman's correlation coefficients and stepwise linear regression were calculated to assess the relationship between cognitive performance and blood nanoparticles. We found that better performance in SDMT and MMSE was related to higher total blood nanoparticles (r = 0.40; p < 0.05). Also, better performance in cognitive processing speed and attention (SDMT) and mental state (MMSE) were related to higher blood iron (r = 0.44; p < 0.03) and zinc concentrations (r = 0.41; p < 0.05), respectively. The other metallic nanoparticles (aluminum, chromium, copper, magnesium, and nickel) did not show a significant relationship with the cognitive parameters (p > 0.05). Linear regression estimated a significant association between blood iron concentration and SDMT performance. In conclusion, blood nanoparticles are related to cognitive performance in pwMS. Our findings suggest that the blood concentration of metallic nanoparticles, particularly the iron concentration, is a promising biomarker for monitoring cognitive impairment in pwMS.

Associations of Whole Blood Zinc Levels with Coronary Artery Calcification and Future Cardiovascular Events in CKD Patients.

This study was conducted to compare the differences of the whole blood zinc concentration in patients with chronic kidney disease (CKD) as compared to healthy controls, and to explore the correlations of the whole blood zinc level with coronary artery calcification (CAC) and cardiovascular event (CVE) in CKD patients. A total of 170 CKD patients and 62 healthy controls were recruited. The whole blood zinc concentration was determined in using atomic absorption spectroscopy (AAS) method. The degrees of CAC were evaluated by Agatston score based on computed tomography (CT). Regular follow-up visits were performed to record the incidence of CVE, and risk factors were analyzed by COX proportional hazard model and Kaplan-Meier survival curve. There were statistically significant lower zinc levels in CKD patients than in healthy population. The prevalence of CAC was 58.82% in CKD patients. Correlation analysis showed that dialysis duration, intact parathyroid hormone (iPTH), alkaline phosphatase (ALP), 25-hydroxyvitamin D3 (25(OH)D3), neutrophil-lymphocyte ratio (NLR), total cholesterol (TC), and high-sensitive C-reactive protein (Hs-CRP) were positively correlated with CAC, while albumin (ALB), hemoglobin (Hb), and zinc levels were negatively associated with CAC. Further COX proportional hazard model demonstrated that moderate to severe CAC, NLR, phosphate, 25(OH)D3, iPTH, and high-density lipoprotein (HDL) were associated with an increased risk for CVE, while zinc levels, Hb, and ALB were inversely associated with a reduced risk for CVE. Kaplan-Meier curve showed that low zinc (zinc < 86.62μmol/L) patients and moderate to severe CAC patients had lower survival respectively. Our study found the lower levels of zinc and higher prevalence of CAC in CKD patients; the low zinc is involved in the high incidence rate of moderate to severe CAC and CVE in CKD patients.

Correlation of endocrine disrupting chemicals with essential elements in biological samples of children (1–5 years) with different infectious diseases and impact on sustainable outdoor activities

Endocrine disrupting chemicals (EDCs) have been extensively explored due to their harmful effects on individual health and the environment by interfering with hormone activity and disrupting the endocrine system. However, their relationship with essential trace elements remains uncertain. This research aimed to investigate the possible correlation between essential trace elements and toxic metals, including cadmium (Cd), and lead (Pb) in children aged 1–5 years with various infectious diseases, including gastrointestinal disorders, typhoid fever, and pneumonia. The study was conducted on biological testing and specimen (scalp hair and whole blood) of diseased and non-diseased children of the same residential area and referent/control age-matched children from developed cities consuming domestically treated water. The media of biological samples were oxidized by an acid mixture before being analyzed by atomic absorption spectrophotometry. The accuracy and validity of the methodology were verified through accredited reference material from scalp hair and whole blood sample. The study results revealed that diseased children had lower mean values of essential trace elements (iron, copper, and zinc) in both scalp hair and blood, except for copper, which was found to be higher in blood samples of diseased children. This implies that the deficiency of essential residue and trace elements in children from rural areas who consume groundwater is linked to various infectious diseases. The study highlights the need for more human biomonitoring of EDCs to better comprehend their non-classical toxic properties and their concealed costs on human health. The findings suggest that exposure to EDCs could be associated with unfavorable health outcomes and emphasizes the need for future regulatory policies to minimize exposure and safeguard the health of current and forthcoming generations of children. Furthermore, the study highlights the implication of essential trace elements in maintaining good health and their potential correlation with toxic metals in the environment.

Effect of Long-Term Proton Pump Inhibitor Use on Blood Vitamins and Minerals: A Primary Care Setting Study.

Long-term proton pump inhibitor (PPI) use is frequently encountered in primary care. Its effect on micronutrient absorption is known, as vitamin B12, calcium or vitamin D insufficiency may occur in such patients. We recruited patients using a PPI (pantoprazole) for >12 months. The control group was represented by subjects attending the general practitioner not taking any PPI in the last 12 months. We excluded subjects using nutritional supplements or with diseases interfering with micronutrient blood levels. All subjects underwent blood sampling with full blood count, iron, ferritin, vitamin D, calcium, sodium, potassium, phosphate, zinc and folate. We recruited 66 subjects: 30 in the PPI group and 36 in the control group. Long-term pantoprazole users had lower red blood cell count but similar hemoglobin. We did not find any significant difference in blood iron, ferritin, vitamin B12 and folate. Vitamin D deficit was observed more frequently in the PPI group (100%) than in controls (30%, p < 0.001), with blood levels lower in pantoprazole consumers. No differences in calcium, sodium and magnesium were observed. Pantoprazole users had lower phosphate levels than controls. Finally, a non-significant trend for zinc deficiency was found in PPI users. Our study confirms that chronic PPI users may encounter alterations in some micronutrients involved in bone mineral homeostasis. The effect on zinc levels deserves further investigation.

Indian food habit & food ingredients may have a role in lowering the severity & high death rate from COVID-19 in Indians: findings from the first nutrigenomic analysis.

During the COVID-19 pandemic, the death rate was reportedly 5-8 fold lower in India which is densely populated as compared to less populated western countries. The aim of this study was to investigate whether dietary habits were associated with the variations in COVID-19 severity and deaths between western and Indian population at the nutrigenomics level. In this study nutrigenomics approach was applied. Blood transcriptome of severe COVID-19 patients from three western countries (showing high fatality) and two datasets from Indian patients were used. Gene set enrichment analyses were performed for pathways, metabolites, nutrients, etc., and compared for western and Indian samples to identify the food- and nutrient-related factors, which may be associated with COVID-19 severity. Data on the daily consumption of twelve key food components across four countries were collected and a correlation between nutrigenomics analyses and per capita daily dietary intake was investigated. Distinct dietary habits of Indians were observed, which may be associated with low death rate from COVID-19. Increased consumption of red meat, dairy products and processed foods by western populations may increase the severity and death rate by activating cytokine storm-related pathways, intussusceptive angiogenesis, hypercapnia and enhancing blood glucose levels due to high contents of sphingolipids, palmitic acid and byproducts such as CO2 and lipopolysaccharide (LPS). Palmitic acid also induces ACE2 expression and increases the infection rate. Coffee and alcohol that are highly consumed in western countries may increase the severity and death rates from COVID-19 by deregulating blood iron, zinc and triglyceride levels. The components of Indian diets maintain high iron and zinc concentrations in blood and rich fibre in their foods may prevent CO2 and LPS-mediated COVID-19 severity. Regular consumption of tea by Indians maintains high high-density lipoprotein (HDL) and low triglyceride in blood as catechins in tea act as natural atorvastatin. Importantly, regular consumption of turmeric in daily food by Indians maintains strong immunity and curcumin in turmeric may prevent pathways and mechanisms associated with SARS-CoV-2 infection and COVID-19 severity and lowered the death rate. Our results suggest that Indian food components suppress cytokine storm and various other severity related pathways of COVID-19 and may have a role in lowering severity and death rates from COVID-19 in India as compared to western populations. However, large multi-centered case-control studies are required to support our current findings.

Cadmium exposure and the risk of prostate cancer among Nigerian men: Effect modification by zinc status

BackgroundProstate cancer (PCa) may result from an interplay between many factors including exposure to trace elements. This study examined the association between cadmium exposure and PCa among Nigerian men and evaluated possible modification of this effect by zinc status. MethodsThis case-control study involved men with histologically confirmed PCa (n = 82), benign prostatic hyperplasia (BPH; n = 93) and controls (n = 98), aged between 40 and 80 years. Study participants were recruited from the main teaching hospital that draws clients from the entire Anambra State in South-Eastern Nigeria. Blood and urine samples were collected from these participants and were analyzed for trace elements using ICP-MS. Statistical models were used to assess the exposure risk for cadmium exposure as well as the mediating effect of zinc status. ResultsAmong men with prostatic disorders (case-case analysis), every 10-fold increase in urinary cadmium was associated with increased risk of PCa (adjusted odds ratios: 2.526; 95% CI: 1.096–5.821). Men in the highest blood zinc quartile had lower odds of PCa compared to the lowest quartile (AOR: 0.19; 95% CI, 0.06–0.54; p-for trend = 0.001). Zinc-specific effect was observed in this group: every 10-fold increase in urinary cadmium was associated with increased risk of PCa among men with creatinine-adjusted urinary zinc levels below the median value (AOR: 8.46; 95% CI: 1.97 –36.39) but not in those above the median value (AOR: 1.55; 95% CI: 0.45 – 5.39). ConclusionHigher exposure to cadmium may be associated with increased risk of PCa in Nigeria and probably other countries with high prevalence of Zn deficiency. These results point to the need to consider co-occurring trace metals in any effort to mitigate the toxicity of Cd in the environment.

Effects of maternal blood selenium and zinc levels on mitochondrial DNA copy number at term and in-turn their effect on the birthweight of the baby

Introduction and Aim: The micronutrients such as selenium and zinc have the antioxidant property. They are cofactors of antioxidant enzymes, regulate the inflammatory response by counterbalancing the oxidative stress. Reduced maternal selenium and zinc levels have been shown to be associated with early pregnancy loss and low birthweight. The aim is to study the effects of maternal blood selenium and zinc levels on mitochondrial DNA copy number at term and in-turn their effect on the birth weight of the baby. Methods: An Institutional ethical clearance was obtained and the present hospital based cross sectional study was conducted in the OBG department of a medical college of North Karnataka between December 2019 to February 2022. Results: A total of 150 term pregnant women participated in the study. There was a slightly increased serum level of zinc and selenium found in the term pregnant mothers who gave birth to normal birth weight babies when compared to low-birth-weight babies, though this difference was not statistically significant. Median (IQR) values of Delta CT values of Mitochondrial DNA copy number in low-birth-weight babies were 3.07(1.7-5.74) and in normal birth weight babies was 3.71 (0.83-4.4). The difference in median values was not statistically significant (p=0.57). We observed a positive correlation between the maternal zinc, selenium, and mitochondrial DNA copy number with birth weight of the baby. Though the correlation between Delta CT means and birthweight of the baby is found to be statistically significant. Conclusion: In the present study, apparently healthy pregnant women participated. The serum selenium and zinc levels were found to be within normal limits according to lab reference values. There was an increase in Mitochondrial DNA copy number in the present study and it was positively correlated with the birthweight of the baby.

Comparative analysis of biochemical, hormonal, and mineral compositions of preovulatory and cystic ovarian follicles in buffalo during the non-breeding season.

This study is a comparative analysis of the biochemical, hormonal, and mineral compositions of follicular fluid in preovulatory and cystic follicles of water buffalo (Bubalus bubalis). In total, reproductive tracts from 215 buffalo along with intact ovaries were collected randomly from an abattoir. The incidence of cystic conditions found in this study was 3.72% (8/215), involving the right ovary in 62.5% of instances and the left ovary in 37.5% of instances during the non-breeding season. Follicular fluid was aspirated from preovulatory follicles (12-15 mm diameter, oestrogen-active, follicular phase or stage IV corpus luteum on one of the two ovaries, n = 10) and cystic follicles (at least 20 mm diameter, no corpus luteum on any one of the two ovaries, n = 8). The follicular fluid samples were assayed for biochemical components (uric acid, creatinine, blood urea nitrogen, cholesterol, total protein, glucose, ascorbic acid, and alkaline phosphatase), hormones (progesterone, estradiol, and insulin), and minerals (calcium, magnesium, phosphorus, copper, zinc, and cobalt). Cystic follicles had greater (P < 0.05) concentrations of creatinine, blood urea nitrogen, cholesterol, progesterone, copper, zinc, and cobalt, and lesser (P < 0.05) concentrations of uric acid, glucose, ascorbic acid, estradiol, insulin, calcium, magnesium, and phosphorus compared with preovulatory follicles. These results indicated the marked differences in follicular fluid composition between preovulatory and cystic follicles in buffalo. Some of the changes were indicative of oxidative stress and disturbed steroidogenesis, two important mechanisms shown to be associated with cystic ovarian disease in various species. Further studies are warranted to investigate whether these differences are directly or indirectly involved in the formation of cystic follicles or are mere manifestations of the condition.

Comparison of Serum Selenium, Homocysteine, Zinc, and Vitamin D Levels in Febrile Children with and without Febrile Seizures: A Prospective Single-Center Study.

Febrile seizure is a complication that makes physicians and families uneasy when detected in children with a high fevers. This study aimed to compare children with febrile seizures and children without seizures in blood selenium, zinc, homocysteine, vitamin D, vitamin B12, and magnesium levels. The study group included sixty-one children between the ages of 1-5 who came to the pediatric emergency department with febrile seizure. The control group had 61 children with fever without seizure, who were compatible with the study group in age, sex, and elapsed time since the onset of fever. Blood samples were taken from the patients during their admission. Selenium, zinc, vitamin D, homocysteine, vitamin B12, and magnesium levels were measured, and the data of the two groups were compared. Additionally, patients in the study group had two subgroups, simple and complex febrile seizures, and their parameters were compared. Selenium, zinc, vitamin D, and vitamin B12 levels were significantly lower in the study group than in the control group (p < 0.001), and there was no significant difference in homocysteine (p = 0.990) and magnesium levels (p = 0.787) between the two groups. Moreover, no significant difference was found between those with simple and complex febrile seizures in selenium, vitamin D, homocysteine, vitamin B12, and magnesium levels. Elevated levels of selenium, zinc, vitamin D, and vitamin B12 in the blood of children with fevers help to prevent febrile seizures.

Role of Copper and Zinc in Full-term Pregnancy and İts Effect on Apgar Score

Objective: Our aim in this study; is to determine zinc, copper and copper/zinc ratios in third-trimester pregnant women with a new laboratory method.&#x0D; Methods: In this research conducted on 59 pregnant women in the last trimester, Those diagnosed with preeclampsia, preterm birth, postmaturity, and gestational diabetes were excluded from the study. In pregnant blood serums, zinc and copper levels were studied on fully automatic analyzers with a new method. The new technique kits used in the study are Rel Assay Diagnostics brand. The zinc ion reacted with 5-Br-PAPS and gave an absorbance at a wavelength of 548 nm in direct proportion to the total zinc level. The copper ion reacted with 3,5-DiBr-PAESA and showed absorbance at 572 nm in direct proportion to the total copper level. Zinc and copper measurements were made in this way by the colourimetric method. Additionally, copper/zinc ratios were calculated. In addition, determined the APGAR (Activity-Pulse-Grimace-Appearance-Respiration) score of the babies. Statistical studies of the obtained data were performed at p&lt;0.05 significance level.&#x0D; Results: Zinc and copper parameters; No statistically significant relationship was found in the analyzes performed with gestational age, gestational week, birth weight, APGAR score, gravida and the number of living children (p&gt;0.05). In addition, it was observed that there was no difference in zinc and copper/zinc ratios in the evaluations made according to the gender of the baby (p&gt;0.05). On the other hand, copper levels in pregnant women; were found to be significantly higher in female fetuses (200.72±36.36) than in males (164.17±42.47) (p&lt;0.001).&#x0D; Conclusion: Although the copper values of pregnant women with female fetuses are significantly higher, these results require more comprehensive studies. On the other hand, there is not relationship between zinc, copper and copper/zinc values and APGAR scores.

RETRACTED: A Mendelian Randomization Analysis Investigates Causal Associations between Inflammatory Bowel Diseases and Variable Risk Factors

The question of whether variable risk factors and various nutrients are causally related to inflammatory bowel diseases (IBDs) has remained unanswered so far. Thus, this study investigated whether genetically predicted risk factors and nutrients play a function in the occurrence of inflammatory bowel diseases, including ulcerative colitis (UC), non-infective colitis (NIC), and Crohn's disease (CD), using Mendelian randomization (MR) analysis. Utilizing the data of genome-wide association studies (GWASs) with 37 exposure factors, we ran Mendelian randomization analyses based on up to 458,109 participants. Univariable and multivariable MR analyses were conducted to determine causal risk factors for IBD diseases. Genetic predisposition to smoking and appendectomy as well as vegetable and fruit intake, breastfeeding, n-3 PUFAs, n-6 PUFAs, vitamin D, total cholesterol, whole-body fat mass, and physical activity were related to the risk of UC (p < 0.05). The effect of lifestyle behaviors on UC was attenuated after correcting for appendectomy. Genetically driven smoking, alcohol consumption, appendectomy, tonsillectomy, blood calcium, tea intake, autoimmune diseases, type 2 diabetes, cesarean delivery, vitamin D deficiency, and antibiotic exposure increased the risk of CD (p < 0.05), while vegetable and fruit intake, breastfeeding, physical activity, blood zinc, and n-3 PUFAs decreased the risk of CD (p < 0.05). Appendectomy, antibiotics, physical activity, blood zinc, n-3 PUFAs, and vegetable fruit intake remained significant predictors in multivariable MR (p < 0.05). Besides smoking, breastfeeding, alcoholic drinks, vegetable and fruit intake, vitamin D, appendectomy, and n-3 PUFAs were associated with NIC (p < 0.05). Smoking, alcoholic drinks, vegetable and fruit intake, vitamin D, appendectomy, and n-3 PUFAs remained significant predictors in multivariable MR (p < 0.05). Our results provide new and comprehensive evidence demonstrating that there are approving causal effects of various risk factors on IBDs. These findings also supply some suggestions for the treatment and prevention of these diseases.

Re-evaluation of locust bean gum (E 410) as a food additive in foods for infants below 16 weeks of age and follow-up of its re-evaluation as a food additive for uses in foods for all population groups.

Locust bean gum (E 410) was re-evaluated in 2017 by the former EFSA Panelon Food Additives and Nutrient sources added to Food (ANS). As a follow-up to that assessment, the Panelon Food Additives and Flavourings (FAF) was requested to assess the safety of locust bean gum (E 410) for its uses as a food additive in food for infants below 16 weeks of age belonging to food category 13.1.5.1 (Dietary foods for infants for special medical purposes and special formulae for infants). In addition, the FAF Panelwas requested to address the issues already identified during the re-evaluation of the food additive when used in food for the general population, including the safety assessment for FC 13.1.5.1 and 13.1.5.2 (Dietary foods for babies and young children for special medical purposes as defined in directive 1999/21/EC). The process involved the publication of a call for data. Based on the received data, the Panelconcluded that the technical data provided by the interested business operators support an amendment of the specifications for locust bean gum (E 410) laid down in Commission Regulation (EU) No 231/2012. The Panelidentified a reference point of 1,400mg/kg bw per day based on reduced blood zinc levels in a piglet study. It applied the margin of exposure (MoE) for the safety assessment of locust bean gum (E 410) when used as a food additive in FC 13.1.5.1 and 13.1.5.2. The Panelconcluded that a MoE above 1 would not raise a safety concern. A MoE above 1 was obtained for some of the scenarios and exposure levels for infants. For toddlers (consumers only of food for special medical purposes), the MoE was above 1 for all exposure levels.

Oral zinc supplementation in management of hepatic encephalopathy in patients with cirrhosis; A study conducted in developing country.

Objective: To evaluate the effectiveness of oral zinc supplementation in cirrhotic patients with hepatic encephalopathy. Study Design: Retrospective Cohort study. Setting: Department of Gastroenterology, Liaquat University of Medical and Health Sciences, Jamshoro. Period: 15th February 2019 to 15th August 2019. Material &amp; Methods: Adult patients of either gender suffering from hepatic cirrhosis and presenting with hepatic encephalopathy of any grade were included. Zinc acetate in a dose of 600 mg was given orally to the patients for two weeks duration. Standard lactulose treatment was also given alongside. Blood ammonia measurement was done at baseline and also after 2 weeks of treatment. Performance was assessed by utilization of number connection test (NCT) at week 1 and week 2 weeks post treatment. Results: Study included of 135 patients among which majority 95 (70.4%) of the patients were males. The mean age of the patients were 55.72 + 10.32 years. 40 (26.62%) patients were seen in Child Pugh class A, 65 (48.14%) were seen in Child Pugh class B and 30 (22.2%) were seen in Child Pugh class C. Serum ammonia levels were reduced in 110 (81.48%) patients and improved performance in NCT was seen in 90 (66.66%) patients. There was significant reduction of ammonia levels and significant improvement of NCT test in male patients (p value &lt;0.05) and in Child Pugh class A and B patients (p value &lt;0.05). Conclusion: In addition to standard therapy, inclusion of oral zinc acetate resulted in normalization of blood zinc and ammonia levels with improved performance in NCT and overall hepatic encephalopathy.
