Background Asthma is a common respiratory disorder; some data were present on the correlation between increased levels of some elements and the risk of asthma development. It was aimed to evaluate the levels of 13 selected blood and tooth elements (magnesium, phosphorus, calcium, chromium, manganese, iron, copper, zinc, strontium, molybdenum, cadmium, lead, mercury) in a well-controlled asthma group and the control group. Methods During the study period, 17 asthma patients and 26 age and gender-matched healthy children donated shed deciduous teeth having neither decay nor filling and enrolled for the study. The element levels in blood and teeth matrixes were analyzed with inductively coupled plasma mass spectrometry. Differences in blood and tooth elements in groups were evaluated with generalized linear models after adjusting confounding factors. Results After adjusting the child’s “z scores of body mass index for age”, history of iron deficiency anemia, and status of parental smoking, the generalized linear model revealed significantly lower tooth magnesium levels, lower blood zinc levels, and lower blood zinc/copper ratio in the asthma group than the control group (p = 0.042, p = 0.034, p = 0.002, respectively). Other studied elements for tooth and blood matrixes were similar in groups. Conclusion Our study revealed some differences in tooth and blood element levels in the asthma group. Further studies on zinc and magnesium levels of severe asthma cases are necessary for the interpretation of the results.

The aim was to evaluate the levels of aflatoxin M1 (AFM1), ochratoxin A (OTA), zearalenone (ZEN), deoxynivalenol (DON) in human milk, and to investigate the relation between selected mycotoxin levels in breast milk and infantile growth in exclusively-breastfed infants under four months. Mycotoxin analysis was performed with commercial ELISA kits. Infants were weighed, and z scores of weight-for-age (WAZ) were calculated with WHO standards. The first quartile of the mycotoxin levels was classified in subgroups as low-level, the last quartile as high-level, and between them as middle-level. The subgroups of AFM1, OTA, and DON had similar infants' WAZ. When cases without maternal smoke exposure were selected and WAZ at birth, infant age, and gender were adjusted, higher infant WAZ on admission was detected in high-ZEN subgroup (p = 0.033). Further cohort studies in exclusively-breastfed infants and absence of maternal smoke exposure could clarify the effect of ZEN on infant growth.

This cross-sectional study with an open-ended manner aimed (1) to evaluate the environmental risk perception levels of mothers having at least one child and living in Adana and (2) to determine their awareness of the risk factors in their environment. Of mothers, 30.2% did not know the concept of environmental risk factor. Most frequent perceived risks were violence (17%), air pollution (15.5%) and undefined pollution (15%). The most common mentioned problems in their environment were air pollution (9.9%), violence (7.9%) and municipal service problems (8.4%). Mothers living in the urban area reported more violence, air pollution and undefined pollution as environmental threats than those living in the countryside. The place of residence, the education level of the mother and the number of people in the house significantly were related with the risk perception. There is a need for studies in other regions to determine the environmental literacy of mothers.

Melamine contamination is a recent public health problem emerging globally. Present study aimed to detect the rate of melamine presence in human milk in a cohort study and to evaluate any possible differences in maternal–infant pair characteristics such as breastfeeding status, crying and sleep problems of infants, maternal postpartum depression, maternal–infant bonding, infant and maternal anthropometry, and maternal complete blood count caused by the melamine exposure. Mothers of infants born in Şanlıurfa were invited to participate in ‘Urfa Child Cohort Survey’. Overall, two breast milk samples were taken between 5 days and 15 days postpartum and between 4 weeks and 10 weeks. Randox Food’s InfiniPlex array was used to analyse the presence of melamine. Melamine was detected in 32.2% and 24.4% of the first and the second milk samples; 16.7% of mothers had two positive samples. z Scores for birth weight and z scores for height for age were detected to be significantly lower in cases with two positive samples compared to cases with negative samples. Mean maternal white blood cells counts were found to be lower in cases with repeated melamine contact. Melamine might have a detrimental effect on birth weight, infant height and maternal blood count. Further studies should be done to detect environmental contamination in different regions and countries.

Background We evaluated (a) opinion of Syrian and Turkish healthcare workers (HCWs), and perceptions and attitudes of Syrian refugee mothers, pregnant women, fathers and grandmothers on age-appropriate breastfeeding, (b) the effect of cultural characteristics, migration and pandemics on Syrian’s infant nutrition, and (c) the suggestions of HCWs and Syrian family members to improve breastfeeding practices in the Syrian refugee society in a qualitative study. Methods The qualitative study consisting of structured focus group discussions (FGDs) was held in four provinces in Turkey where Syrian refugees live intensely in September and October 2020. Seven different types of online FGDs were held with Turkish HCWs working in maternity hospitals, Syrian HCWs working in Refugee Health Centers (RHCs), Syrian pregnant women, mothers, fathers, and grandmothers. In total, we carried out 46 FGDs with 335 individuals. Thematic analysis of the transcripts in a deductive-inductive fashion was carried out with MAXQDA 11. Results Most Syrian HCWs did not get any training on breastfeeding counseling. The short duration of breastfeeding in Syrian refugees was seen to be related to the cultural characteristics, and migration. Some cultural characteristics can be summarized as “believing that breastfeeding harms mother’s health”, “adolescent marriages”, “wanting to have as many children as possible”, “giving anise to infants and not breastfeeding at night”, “prelacteal feeding”, “believing that milk is not enough”, “over controlling mother–child interaction by grandmothers, which limits the interaction”, “short pregnancy intervals”, and “not using modern family planning techniques”. We found out that migration increased the tendency for adolescent pregnancies, deepened the poverty, and decreased family social support. We did not observe any change in breastfeeding practices during pandemics. Conclusions Breastfeeding counseling programs should be designed in consideration of cultural characteristics of Syrian HCWs and family members. Continuing health education programs for family members with socially appropriate interventions to prevent adolescent marriages are important.

Background Some elements were claimed to play a role in the pathogenesis of congenital heart defects (CHD) and influence the general well-being and health of these children. Objectives We aimed to assess the levels of some elements simultaneously in the blood and teeth samples of children with cyanotic and acyanotic CHD compared with healthy children. Methods A total of 39 children with CHD (11 with cyanotic and 28 with acyanotic CHD) and 42 age- and sex-adjusted controls were enrolled. Levels of 13 elements, including magnesium, phosphorus, calcium, chromium, manganese, iron, copper, zinc, strontium, cadmium, lead, mercury, and molybdenum, were assessed using inductively coupled plasma mass spectrometry. Results Children with cyanotic and acyanotic CHD had significantly lower teeth calcium and calcium/phosphorus ratio as compared to the controls after adjusting for confounders. The mean blood iron level was found to be significantly higher in the cyanotic CHD group compared to the other groups. In addition, children with acyanotic CHD had significantly higher teeth copper levels, higher blood molybdenum and lower blood magnesium levels compared to the healthy control group. Blood cadmium and mercury levels were found to be significantly elevated in both the cyanotic and acyanotic CHD groups compared to the healthy control group. There were no differences in toxic metal levels of teeth in cases with CHD. Conclusion Monitoring adequate and balanced gestational micronutrient intake might support not only maternal health but also fetal cardiac development and infant well-being. Supplementation of magnesium should be evaluated in patients having CHD.

The aim was to evaluate the changes in aflatoxin M1 (AFM1) and ochratoxin A (OTA) levels in human breast milk (HBM) during the first five postpartum months according to the sampling season in a cohort study from Şanlıurfa. From 78 healthy lactating mothers, HBM was taken at the 5-14 days postpartum (D5-14) and the 6

Objective:The aim of the current study is to analyse the trends, determinants of prelacteal feeding (PLF) and its relations with the mode of delivery among infants Design:We pooled data from Turkey Demographic and Health Surveys (TDHS). The key outcome variable was PLF. Factors associated with PLF were analysed by using complex sample multiple logistic regression analysis, separately and merged database.Setting:TDHS in 2003, 2008, 2013 and 2018.Participants:Mother–infant dyads (n 4942).Results:PLF rates fluctuated between 29·3 and 41·4 %. The most common types of PLF were infant formula (61·1 %) followed by sugar/glucose water (24·9 %) and plain water (9·3 %). PLF rate was 1·51 times higher (95 % CI 1·28, 1·78) in cases delivered by caesarean section as compared with those delivered by vaginal route. According to the initiation time of breast-feeding after delivery, the most significant absolute change in PLF rate was observed within 1 h (10·9 % increase). Delayed initiation of breast-feeding was associated with significantly higher odds of PLF compared with the first hour (1 to < 2 h: adjusted OR (AOR) 1·29, 95 % CI 1·04, 1·61; 2–23 h: AOR 1·73, 95 % CI 1·42, 2·11; ≥24 h: AOR 11·37, 95 % CI 8·81, 14·69).Conclusions:To eliminate suboptimal breast-feeding practices, counselling on breast-feeding and delivery type during antenatal visits, postnatal breast-feeding support and social support should be provided to all mothers and families.

Maternal milk is essential for optimum growth and development of an infant. The aim was to examine the presence of pharmaceutical residuals in breastmilk. This cohort study enrolled 90 healthy mother-infant pairs at 5-14 days after delivery and a control examination was performed 4-8 weeks later. Milk samples were taken at both visits. RANDOX Infiniplex kit performed residual analysis. More than half of mothers (54.4 %) had anti-inflammatory drug residues in at least one milk sample: those were 52.2 % for tolfenamic acid and 2.2 % for meloxicam and 1.1 % for metamizole. The most frequent residue group included the beta-lactam antibiotic group, which was detected in 93.3 % of mothers' milk. The second one was the quinolone group (81.1 %). One-third of mothers expressed nitroxynil and one-fifth polymyxin in at least one sample. Almost all mothers had some unexpected drug residues in their milk. Additional studies from other countries can display maternal environmental exposures.

Background The study aimed to provide an overall picture of the general pattern of exclusive breast feeding (EBF) in sub-Saharan Africa (SSA) by examining maternal sociodemographic, antenatal and postnatal factors associated with EBF in the region, as well as explore countries variations in EBF rates. Methods We utilised cross-sectional data from the Demographic Health Surveys in 27 SSA countries. Our study sample included 25 084 infants under 6 months of age. The key outcome variable was EBF in the last 24 h. Due to the hierarchical structure of the data, a multilevel logistic regression model was used to explore factors associated with EBF. Results The overall prevalence of EBF in SSA was 36.0%, the prevalence was highest in Rwanda and lowest in Gabon. In the multilevel regression model, factors that were associated with increased likelihood of EBF included secondary and above maternal education, mothers within the ages of 25–34 years, rural residence, richer household wealth quantile, 4+ antenatal care visit, delivering in a health facility, singleton births, female infants, early initiation of breast feeding (EIBF), and younger infants. However, countries with higher gross national income per capita had lower EBF rates. Conclusions To achieve a substantial increase in EBF rates in SSA, breast-feeding interventions and policies should target all women but with more emphasis to mothers with younger age, low educational status, urban residence, poor status, multiple births, and male infants. In addition, there is a need to promote antenatal care utilisation, hospital deliveries, and EIBF.

Background Environmental factors, including elemental homeostasis, have not been studied sufficiently in neurodevelopmental disorders (NDD). This study aims to compare the status of 13 elements in blood and deciduous teeth dentine of children having an autism spectrum disorder or attention deficit hyperactivity disorder with typically developing controls. Methods Elements including calcium, phosphorus, magnesium, iron, zinc, copper, chromium, manganese, mercury, lead, cadmium, molybdenum, and strontium in both deciduous teeth and blood were analyzed by inductively coupled plasma mass spectrometry. Results Strontium levels in both blood and teeth samples were found to be significantly lower in the NDD group. Additionally, blood cadmium and mercury levels, and copper/zinc ratio were higher in the NDD group. Conclusions Our results warrant further investigation in a large series of NDD examining symptom levels and genetic variations associated with elemental homeostasis.

This study was conducted to assess the blood boron levels (BBL) in prepubertal children in the West and Central Anatolia regions of Turkey and its relationship with chosen anthropometric measurements. A multistage sampling design that combined multicluster (West Anatolia vs. Central Anatolia regions and rural vs. urban residents) and simple random sampling methods were used for the sample selection. BBL was measured using inductively coupled plasma mass spectrometry. Weight, height, mid-arm circumference, and triceps skinfold thickness were measured. Z-scores for weight-for-age, height-for-age, and body mass index (BMI)-for-age were calculated. Furthermore, arm-muscle area, arm-fat area, and fat percentage were measured. This study enrolled 2126 children, of whom 50.7% were male. The mean age was 8.9 years. The mean concentration of BBL was 15.6 μg/L (interquartile range: 11.7-19.6 μg/L). Children in urban areas had significantly higher BBL than those in rural areas (17.2 ± 5.5 vs. 11.9 ± 4.6 μg/L; p

We aimed to determine the levels of organochlorine pesticides (OCPs) in the breast milk; to assess the effect of detectable OCPs on maternal-infant characteristics and; to evaluate the relation between OCPs and the maternal psychopathologies [Brief Symptom Inventory (BSI), Postpartum Bonding Questionnaire (PBQ), Mother-to-Infant Bonding Scale (MIBS) and Edinburgh Postnatal Depression Scale (EPDS)] and infant growth. DDT, beta-hexachlorocyclohexane (HCH), aldrin and heptachlor were detected in 89.3, 70.7, 58.7 and 34.7 % of the samples, respectively. Mothers with low monthly family income had detectable DDTs less frequently. The frequencies of detectable heptachlor epoxide were significantly higher in mothers with gestational nausea. Anaemic mothers had more frequently detectable alpha-HCH. Z scores of head circumference were inversely correlated with beta-HCH and DDT levels. The heptachlor epoxide levels were positively correlated with PBQ, MIBS and indexes of BSI. No relation was detected between EPDS and OCPs. Further studies are needed for changes in maternal psychopathologies.

WOS: 000295754300007, PubMed: 22026291, Aim: To evaluate the association between anthropometric measurements and dental caries in school children. Methods: The study was conducted on 245 primary school children (50.2% boys, 49.8% girls,), aged 5 to 9 years. The prevalence and severity of dental caries was measured using the decayed, missing or filled surfaces (dmfs, DMFS) and teeth (dmft, DMFT) indices. Results: Mean dmft indices in children for boys and girls were 5.5 +/- 3.92 and 5.0 +/- 3.64, respectively. The prevalence of children with dental caries (dmft >= 1) was 84.9%. The prevalence of children with body mass index (BMI) =+1SD was 15.9% and 22.9%, respectively. Dental caries were found in 89.7% of children with low body weight (including underweight and at risk for underweight) and in 66.1% of overweight-obese children (p, Ankara Rotary Club; Dazen Laboratory, This study was supported by projects of Ankara Rotary Club and Dazen Laboratory. We are grateful to the teachers and parents.

WOS: 000296263900031, PubMed: 22010253, This study was conducted to determine the effect of hen production cycle (HPC) and the effect of egg weight (EW) at the same egg production level on egg quality, egg composition, hatchability, duckling quality, and first-week BW in Pekin ducks. For HPC, hatching eggs were obtained from different Pekin-duck breeder flocks, aged 31 wk for the first production cycle (HPC1) and 78 wk for the second production cycle (HPC2). For EW, there were 3 categories: heavy (H), medium (M), and light (L). Ten eggs from each HPC and EW group were analyzed for the determination of egg quality, and albumen and yolk compositions. Ninety eggs from each HPC and EW group were incubated for the determination of hatchability, and duckling weight and quality. After quality scoring, 20 ducklings (10 male and 10 female) from each group were weighed, and reared to 1 wk of age in a brooder machine to determine relative growth (RG). The results showed that the albumen index; Haugh unit; shell percentage; yolk moisture, ash, protein, lipids, and triglycerides; albumen moisture, ash, and protein; yolk fatty acid contents; hatching weight; duckling weights at 1 wk of age; and RG were significantly affected by HPC. Egg weight affected shell thickness, yolk and albumen indices, Haugh unit, yolk and albumen percentages, yolk to albumen ratio, shell percentage, yolk fatty acid content, hatching weight, duckling weight at 1 wk of age, and RG.

BACKGROUND: The objective of this study was to determine the effects of dietary yeast autolysate on performance, egg traits, egg cholesterol content, egg yolk fatty acid composition, lipid oxidation of egg yolk, some blood parameters and humoral immune response of laying hens during a 16 week period. A total of 225 Hyline Brown laying hens, 22 weeks of age, were allocated equally to one control group and four treatment groups. Yeast autolysate (Saccharomyces cerevisiae, InteWall) was used at levels of 1, 2, 3 and 4 g kg−1 in the diets of the first, second, third and fourth treatment groups respectively. RESULTS: Dietary treatments did not significantly affect body weight, feed intake and egg traits. Yeast autolysate supplementation increased egg production (P < 0.001) and egg weight (P < 0.001) and improved feed efficiency (P < 0.05). Yeast autolysate at levels of 2, 3 and 4 g kg−1 decreased egg yolk cholesterol level as mg g−1 yolk (P < 0.01) and blood serum levels of cholesterol and triglyceride (P < 0.05) and increased antibody titres to sheep red blood cells (P < 0.01). Total saturated fatty acids and the ratio of saturated/unsaturated fatty acids increased (P < 0.01) and total monounsaturated fatty acids (P < 0.001) decreased with yeast autolysate supplementation. CONCLUSION: Dietary yeast autolysate at levels of 2, 3 and 4 g kg−1 had beneficial effects on performance, egg cholesterol content and humoral immune response. It is concluded that 2 g kg−1 yeast autolysate will be enough to have beneficial effects in laying hens. Copyright © 2010 Society of Chemical Industry

We aimed to evaluate the maternal factors [including dietary habits, dental care, smoking, anemia, levels of breast-milk zinc (Zn) and iron (Fe), and levels of serum selenium (Se), Zn and copper (Cu)] that influence breast-milk mercury (Hg) concentrations and to investigate whether there is any relation between Hg concentrations and infant growth and development during the exclusive breastfeeding period and in the second year of life. Forty-four healthy mother-infant pairs in the 10-20-day postpartum period were enrolled in the study. Maternal history and blood samples for hemoglobin, Fe, Fe binding capacity, ferritin, Se, Zn, and Cu and breast-milk samples for Fe, Zn and Hg were taken. Infant growth and development during the exclusive breastfeeding period and in the second year of life were followed. The mean concentration of breast-milk Hg was 3.42 +/- 1.66 microg/L. Serum Se levels were negatively correlated with milk Hg levels. Multivariate analysis revealed that active/passive smoking and offal intake during pregnancy and presence of maternal anemia had an impact on increased milk Hg concentrations. Preventive strategies for mercury exposure should include management of iron deficiency anemia, cessation of smoking exposure and proper nutrition during the pregnancy period.

This study was conducted to investigate the effects of dietary dried baker’s yeast on laying performance, egg traits and some blood parameters of quails. In the experiment a total of 342 Japanese quails (Coturnix coturnix japonica) aged ten weeks were equally divided into six groups of 57 (three replicates of 19 quails each). Six levels (0, 4, 8, 12, 16 and 20%) of dried baker’s yeast were included in isonitrogenous and isocaloric diets. The experimental period lasted 14 weeks. At the end of the experiment, there were no significant differences among the groups in body weight, feed intake, protein intake, egg production, feed efficiency, egg yolk index and egg haugh unit. Blood serum levels of total protein, triglyceride and cholesterol were not affected by dietary dried baker’s yeast. Diets containing 4 and 8% of dried baker’s yeast increased the egg weight significantly (p < 0.01). The inclusion of dried baker’s yeast at the level of 20% to the diets reduced egg shell thickness and egg albumen height. It is concluded that dried baker’s yeast can be used up to 16% in the diets of laying quails without adverse effects on the measured parameters.

WOS: 000231641800009, PubMed: 16156131, This experiment was carried out to determine the effects of using L-carnitine and humate alone or in combination in quail diets on laying performance, egg traits and blood parameters. A total of 280 Japanese quails aged 10 weeks, divided into one control group and three treatment groups, were used. The diets of the first, second and third treatment groups were supplemented with 100 mg L-carnitine/kg, 1.5 g humate (Farmagulator (R) Dry Plus)/kg and 100 mg L-camitine + 1.5 g humate/kg, respectively. The experimental period lasted 16 weeks. The addition of L-camitine and sodium humate alone or in combination did not significantly affect body weight, feed consumption, egg production, feed conversion ratio, mortality, egg-shell thickness, egg yolk index and the percentages of egg-shell, albumen and yolk. Egg weight increased (P < 0.001) with L-camitine supplementation. The values of egg albumen height (P < 0.05), egg albumen index (P < 0.01) and egg Haugh unit (P < 0.05) were increased with humate supplementation. Egg cholesterol content and blood serum parameters were not affected by the supplementation of L-camitine with or without humate. The results in this study demonstrated that L-carnitine supplementation increased egg weight while humate addition increased egg albumen index and egg Haugh unit of laying quails. However, the combined administration of L-camitine and humate did not have any significant effects on the parameters measured.

The aim of the study was to evaluate how and when adolescent students washed their hands and to detect the conditions that affect hand washing in schools. Seven schools were selected in Konya, Turkey. A questionnaire assessing the answers of 'how long', 'when' (frequency of hand-washing in six conditions with a Likert scale; after toilet, before eating, after eating, entering the home, cleaning a room, when sneezed or coughed), 'how' (hand-washing techniques) and 'why' was given to students. According to self report, person who washed his hands more than or equal to 20 sec and had adequate washing techniques (with soap and water) and had washing frequency score more than 20 was defined as having 'proper basic handwash'. Of a total of 1074 students, 1021 responded. According to self reported behaviours and attitudes, soap and water were used in 99.2% of hand washes, and an alcohol preparation was used in 0.2% of cases and wet paper was used in the remaining 0.6% in the schools. The average duration of soap and water washes was 41.8 +/- 39.1 sec. Overall, 42.4% of adolescents had a proper basic handwash. In multivariate analysis female sex, living at home, high knowledge level and urban school were associated with high proper basic handwash. In addition to this, the presence of some complaints about toilets in school affected proper basic hand wash in univariate analysis. Contrary to what had been expected, a factor such as type of school (health trade school) was not found to be associated with high proper basic handwash in both multivariate and univariate analysis. As a result, adolescents have limited knowledge about indications of hand-washing and some problems adversely influenced hand-washing. To increase compliance, problems should be solved and lessons about hand-washing and communicable disease should be given.
