Impact of Heat-Killed Lactobacillus casei Strain IMAU60214 on the Immune Function of Macrophages in Malnourished Children. Nutrients 2020; 12:nu12082303. [PMID: 32751919 PMCID: PMC7468933 DOI: 10.3390/nu12082303] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Revised: 07/17/2020] [Accepted: 07/30/2020] [Indexed: 12/17/2022] Open
Abstract
Malnutrition is commonly associated with immunological deregulation, increasing the risk of infectious illness and death. The objective of this work was to determine the in vitro effects of heat-killed Lactobacillus casei IMAU60214 on monocyte-derived macrophages (MDMs) from well-nourished healthy children, well-nourished infected children and malnourished infected children, which was evaluated by an oxygen-dependent microbicidal mechanism assay of luminol-increase chemiluminescence and the secretion of tumor necrosis factor (TNF-α), interleukin (IL-1β), IL-6 and IL-10, as well as phagocytosis using zymosan and as its antibacterial activity against Salmonella typhimurium, Escherichia coli and Staphylococcus aureus. We found that reactive oxygen species (ROS), secretion cytokines (TNFα, IL-1β, IL-6 and IL-10 levels), phagocytosis and bactericidal capacity increased in all groups after pre-treatment with heat-killed L. casei IMAU60214 at a ratio of 500:1 (bacteria:MDM) over 24 h compared with MDM cells without pre-treatment. The results could indicate that heat-killed L. casei IMAU60214 is a potential candidate for regulating the immune function of macrophages.

Assessment of Micronutrient Status in Critically Ill Children: Challenges and Opportunities. Nutrients 2017; 9:nu9111185. [PMID: 29143766 PMCID: PMC5707657 DOI: 10.3390/nu9111185] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2017] [Revised: 10/19/2017] [Accepted: 10/20/2017] [Indexed: 02/06/2023] Open
Abstract
Micronutrients refer to a group of organic vitamins and inorganic trace elements that serve many functions in metabolism. Assessment of micronutrient status in critically ill children is challenging due to many complicating factors, such as evolving metabolic demands, immature organ function, and varying methods of feeding that affect nutritional dietary intake. Determination of micronutrient status, especially in children, usually relies on a combination of biomarkers, with only a few having been established as a gold standard. Almost all micronutrients display a decrease in their serum levels in critically ill children, resulting in an increased risk of deficiency in this setting. While vitamin D deficiency is a well-known phenomenon in critical illness and can predict a higher need for intensive care, serum concentrations of many trace elements such as iron, zinc, and selenium decrease as a result of tissue redistribution in response to systemic inflammation. Despite a decrease in their levels, supplementation of micronutrients during times of severe illness has not demonstrated clear benefits in either survival advantage or reduction of adverse outcomes. For many micronutrients, the lack of large and randomized studies remains a major hindrance to critically evaluating their status and clinical significance.

Abstract
BACKGROUND A rare but reversible cause of dilated cardiomyopathy occurs in infants born to vitamin D deficient mothers due to hypocalcaemia. CASE REPORT We report a case of dilated cardiomyopathy due to hypocalcaemia secondary to maternal vitamin D deficiency in an infant presented with seizure disorder and heart failure. This was a four-month old female infant with respiratory distress and acute heart failure. The cause of her cardiac failure was dilated cardiomyopathy. Concomitant community acquired pneumonia was diagnosed on chest X ray. Despite treatment, the infant's clinical condition worsened. The mother was found to be house-bound, dark skinned and veiled while going outside of home. Laboratory studies revealed hypomagnesaemia and hypocalcaemia. The vitamin D levels of both the infant and the mother were found to be low. The infant was treated for the deficiency state until her cardiac condition fully recovered. CONCLUSION This case report demonstrated the direct relationship between maternal vitamin D deficiency and the infant's acute heart failure. It also highlighted the importance of vitamin D supplementation during pregnancy in order to prevent the cardiac complication of maternal vitamin D deficiency in the infants.

Abstract
BACKGROUND Poor growth and micronutrient deficiency mainly attack older infants and young children. Some countries have adopted clinically effective measures to combat malnutrition, but the compliance and improvement in efficacy of intervention vehicles in national programs require evaluation. METHODS Baseline and follow-up cross-sectional surveys were conducted before and after a nutrition intervention program in 3 national poverty counties in China. Soybean-based complementary food supplements called Yingyangbao (YYB) in Chinese and training materials on child feeding were distributed to households with children aged 6-23 months for 18 months. Representative children were selected by probability proportional to size sampling methods to assess compliance of YYB and the intervention efficacy. A questionnaire was designed to collect data on basic characteristics of children, breastfeeding, 24-hour dietary intake, and consumption and appetite of YYB. Anthropometrics and hemoglobin were measured in the field, and anemia prevalence was evaluated. Venous blood was drawn from children aged 12-35 months to evaluate micronutrient status. Logistic regression was used to identify the risk factors for children's anemia. RESULTS Of the children involved in the follow-up survey (n = 693), the P50 (P25, P75) intake of YYB was 6.7 (3.5, 7.0) sachets weekly, and 54.7% of the children liked the taste of YYB. Compared with the baseline situation (n = 823), the proportion of children fed a diverse diet and foods rich in iron or vitamin A increased (P < 0.01) in the follow-up study. The prevalence of stunting and underweight decreased (P < 0.05), the prevalence of anemia decreased from 28.0% to 19.9% (P < 0.01), and the prevalence of vitamin B12 deficiency decreased from 26.8% to 15.4% (P < 0.01). For children aged 12-23 months, those who liked YYB and consumed 6 or more sachets of YYB weekly were at lower risk for anemia (OR = 0.34, 95% CI 0.13-0.90, P < 0.05), but the risk of stunting was associated with a non-diverse diet (OR = 1.48, 95% CI 1.06-2.07, P < 0.05). CONCLUSION The quality of diet and nutritional status of children aged 6-23 months are significantly improved by the intervention of YYB and nutrition education, and good compliance to YYB contributes to a low risk for anemia.

Abstract
Infants in developing countries are at risk of concurrent micronutrient deficiencies, because the same causative factors may lead to deficiencies of different micronutrients. Inadequate dietary intake is considered one of the major causes of micronutrient deficiencies, especially among poor and underprivileged children in developing countries. Operational strategies and distribution systems are often duplicated when supplementation programs for single micronutrients are implemented at the same time. The International Research on Infant Supplementation (IRIS) trial was conducted in four distinct populations on three continents: Africa, Latin America, and Asia. The participating countries were South Africa, Peru, Vietnam, and Indonesia. The study had a randomized, doubleblind, placebo-controlled design. Each country aimed to enroll at least 70 infants per intervention group (65 + 5 anticipated dropouts). The micronutrient vehicle was in the form of a “foodlet” (food-like tablet) manufactured as chewable tablets, which were easy to break and dissolve, and which had the same taste, color, and flavor for all countries. Children were randomly assigned to one of four 6-month intervention groups: group 1 received a daily foodlet containing multiple micronutrients; group 2 received a daily placebo foodlet containing no micronutrients; group 3 received a weekly foodlet that contained multiple micronutrients (twice the dose of the daily foodlet) and placebo foodlets on the other days of the week; group 4 received a daily foodlet containing only 10 mg of elemental iron. The IRIS Trial aimed to examine the prevalence of multi-micronutrient deficiencies in 6- to 12-month-old infants from rural populations, and to examine the efficacy of multi-micronutrient supplementation in infants from the different countries included in the study. This paper describes the general methodology of the IRIS trial and the operational differences among the country sites.

Abstract
Maternal vitamin D status during pregnancy has been associated with infant birth and postnatal growth outcomes, but reported findings have been inconsistent, especially in relation to postnatal growth and adiposity outcomes. In a mother-offspring cohort in Singapore, maternal plasma vitamin D was measured between 26 and 28 weeks of gestation, and anthropometric measurements were obtained from singleton offspring during the first 2 years of life with 3-month follow-up intervals to examine birth, growth and adiposity outcomes. Associations were analysed using multivariable linear regression. Of a total of 910 mothers, 13·2 % were vitamin D deficient (<50 nmol/l) and 26·5 % were insufficient (50-75 nmol/l). After adjustment for potential confounders and multiple testing, no statistically significant associations were observed between maternal vitamin D status and any of the birth outcomes - small for gestational age (OR 1·00; 95 % CI 0·56, 1·79) and pre-term birth (OR 1·16; 95 % CI 0·64, 2·11) - growth outcomes - weight-for-age z-scores, length-for-age z-scores, circumferences of the head, abdomen and mid-arm at birth or postnatally - and adiposity outcomes - BMI, and skinfold thickness (triceps, biceps and subscapular) at birth or postnatally. Maternal vitamin D status in pregnancy did not influence infant birth outcomes, postnatal growth and adiposity outcomes in this cohort, perhaps due to the low prevalence (1·6 % of the cohort) of severe maternal vitamin D deficiency (defined as of <30·0 nmol/l) in our population.

Abstract
Children with severe malnutrition have a dysfunction of the immune response that can significantly increase morbidity and mortality from infections. The aim of this investigation was to evaluate the effect of nutritional recovery in serum measurements of inflammatory cytokines; such as interleukin 12 (IL-12), interleukin 17 (IL-17), interferon gamma (IFN-γ) and tumor necrosis factor alpha (TNF-α). In a prospective and longitudinal study, 24 severe malnourished children aged between 1 and 2 years-old, who were part of a program of nutritional recovery, were selected based on clinical and anthropometric criteria. Serum measurements of cytokines were determined before and after dietary treatment, using the technique of sandwich Enzyme-Linked ImmunoSorbent Assay (ELISA). For comparisons, Student’s t test was used, considered p <0.05 as statistically significant. A difference was observed in the concentrations of IL-12, IL-17, IFN-γ and TNF-α before and after treatment (p <0.05), which suggests that malnutrition provokes an inflammatory state and two months of intensive nutritional support, not only promotes the clinical recovery of severe malnourished children, but also the recovery of the immune response with regard to the production of soluble mediators, such as cytokines.

Abstract
Hypocalcaemia is common in severely-malnourished children and is often associated with fatal outcome. There is very limited information on the clinical predicting factors of hypocalcaemia in hospitalized severely-malnourished under-five children. Our objective was to evaluate the prevalence, clinical predicting factors, and outcome of hypocalcaemia in such children. In this case-control study, all severely-malnourished under-five children (n=333) admitted to the Longer Stay Ward (LSW), High Dependency Unit (HDU), and Intensive Care Unit (ICU) of the Dhaka Hospital of icddr,b between April 2011 and April 2012, who also had their total serum calcium estimated, were enrolled. Those who presented with hypocalcaemia (serum calcium <2.12 mmol/L) constituted the cases (n=87), and those admitted without hypocalcaemia (n=246) constituted the control group in our analysis. The prevalence of hypocalcaemia among severely-malnourished under-five children was 26% (87/333). The fatality rate among cases was significantly higher than that in the controls (17% vs 5%; p < 0.001). Using logistic regression analysis, after adjusting for potential confounders, such as vomiting, abdominal distension, and diastolic hypotension, we identified acute watery diarrhoea (AWD) (OR 2.19, 95% CI 1.08-4.43, p = 0.030), convulsion on admission (OR 21.86, 95% CI 2.57-185.86, p = 0.005), and lethargy (OR 2.70, 95% CI 1.633-5.46, p = 0.006) as independent predictors of hypocalcaemia in severely-malnourished children. It is concluded, severely-malnourished children presenting with hypocalcaemia have an increased risk of death than those without hypocalcaemia. AWD, convulsion, and lethargy assessed on admission to hospital are the clinical predictors of hypocalcaemia in such children. Presence of these features in hospitalized children with severe acute malnutrition (SAM) should alert clinicians about the possibility of hypocalcaemia and may help undertake potential preventive measures, such as calcium supplementation, in addition to other aspects of management of such children, especially in the resource-poor settings.

Abstract
Micronutrient deficiencies exist among women of childbearing age in the United Arab Emirates but the effects of maternal micronutrient deficiency on fetal growth are not well documented. To investigate the association between micronutrients and birth weight, we measured maternal and cord blood micronutrients (vitamin A, C, D, and E) and ferritin in 84 term, singleton infants born to healthy Arab and South Asian women at Al-Ain hospital. Median serum ascorbic acid and 25-hydroxyvitamin D (25-OHD) concentrations were low in mothers and infants. In multivariate analysis, maternal serum 25-OHD correlated positively with birth weight while serum ferritin showed a negative correlation.

Abstract
Malnutrition continues to be a major health burden in developing countries. Flow cytometric estimation of the apoptotic marker CD95 in peripheral neutrophils, lymphocytes and monocytes was done for 18 infants with non-oedematous protein energy malnutrition (PEM) and 12 oedematous ones, on hospital admission and after supervised nutritional rehabilitation, and compared with 12 matched controls. CD95 counts in the 3 types of white blood cells were significantly higher in PEM infants and showed improvement after nutritional rehabilitation yet not reaching the control values. Enhanced apoptosis in the leukocytes of peripheral blood of PEM patients may be a marker of increased infection and immune disturbances. This derangement reverses upon proper nutritional rehabilitation.

Abstract
BACKGROUND In Mexico, as in other developing countries, micronutrient deficiencies are common in infants between 6 and 24 months of age and are an important public health problem. The objective of this study was to determine the prevalence of anemia and of iron, folic acid, and zinc deficiencies in Mexican children under 2 years of age who use the health care services provided by the Mexican Institute for Social Security (IMSS). METHODS A nationwide survey was conducted with a representative sample of children younger than 2 years of age, beneficiaries, and users of health care services provided by IMSS through its regular regimen (located in urban populations) and its Oportunidades program (services offered in rural areas). A subsample of 4,955 clinically healthy children was studied to determine their micronutrient status. A venous blood sample was drawn to determine hemoglobin, serum ferritin, percent of transferrin saturation, zinc, and folic acid. Descriptive statistics include point estimates and 95% confidence intervals for the sample and projections for the larger population from which the sample was drawn. RESULTS Twenty percent of children younger than 2 years of age had anemia, and 27.8% (rural) to 32.6% (urban) had iron deficiency; more than 50% of anemia was not associated with low ferritin concentrations. Iron stores were more depleted as age increased. Low serum zinc and folic acid deficiencies were 28% and 10%, respectively, in the urban areas, and 13% and 8%, respectively, in rural areas. The prevalence of simultaneous iron and zinc deficiencies was 9.2% and 2.7% in urban and rural areas. Children with anemia have higher percentages of folic acid deficiency than children with normal iron status. CONCLUSION Iron and zinc deficiencies constitute the principal micronutrient deficiencies in Mexican children younger than 2 years old who use the health care services provided by IMSS. Anemia not associated with low ferritin values was more prevalent than iron-deficiency anemia. The presence of micronutrient deficiencies at this early age calls for effective preventive public nutrition programs to address them.

Abstract
Protein-energy malnutrition promotes adaptive hormonal changes that result in stunting. A previous study showed that stunted children had increased insulin sensitivity and diminished pancreatic beta-cell function. The objectives of the present study were to analyse the glucose, insulin, homeostasis model assessment of insulin sensitivity (HOMA-S) and homeostasis model assessment of pancreatic beta-cell function (HOMA-B) levels after nutritional recovery. The recovered group (n 62) consisted of malnourished children after treatment at a nutrition rehabilitation centre. At the beginning of treatment their age was 2.41 (sd 1.28) and 2.31 (sd 1.08) years, weight-for-age Z score - 2.09 (sd 0.94) and - 2.05 (sd 0.55) and height-for-age Z score - 1.85 (sd 1.11) and - 1.56 (sd 0.90), for boys and girls respectively. The control group consisted of well-nourished children without treatment (n 26). After treatment, boys of the recovered group gained 1.29 (sd 1.06) Z scores of height-for-age and 1.14 (sd 0.99) Z scores of weight-for-age, and girls, 1.12 (sd 0.91) and 1.21 (sd 0.74) Z scores respectively. No differences were found between control and recovered groups in insulin levels for boys (P = 0.704) and girls (P = 0.408), HOMA-B for boys (P = 0.451) and girls (P = 0.330), and HOMA-S (P = 0.765) for boys and girls (P = 0.456) respectively. The present study shows that the changes observed previously in glucose metabolism and insulin were reverted in children who received adequate treatment at nutritional rehabilitation centres and showed linear catch-up.

Abstract
BACKGROUND Infants aged 6-24 mo are at high risk of iron deficiency. Numerous studies worldwide have sought to identify predictors of iron deficiency in this age group. OBJECTIVE The objectives of the study were to apply a physiologic model to identify risk factors for iron deficiency and to consider those risk factors under different conditions of iron supplementation. We predicted that factors related to iron status at birth (lower gestational age and lower birth weight), postnatal needs for iron (more rapid growth), and bioavailable iron (more cow milk) would be major risk factors. DESIGN The physiologic framework was assessed in 1657 Chilean infants (aged 12 mo) with birth weights >or=3 kg who were randomly assigned at age 6 mo to high or low iron supplementation or no added iron. Based on venous blood, the analysis used mean corpuscular volume and concentrations of hemoglobin, free erythrocyte protoporphyrin, and ferritin. Logistic regression models were used to identify predictors of iron deficiency anemia and iron deficiency without anemia. RESULTS The prevalence of iron deficiency (>or=2 abnormal iron measures) was 34.9% at age 12 mo. Of 186 infants with hemoglobin concentrations <110 g/L, 158 (84.9%) were iron deficient. The only consistent (and the strongest) predictor of iron deficiency or iron deficiency anemia was lower 6-mo hemoglobin. Factors related to poorer iron status at birth (lower birth weight, shorter gestation though full-term, or both) were predictors in the no-added-iron and high-iron groups. Otherwise, predictors varied by iron supplementation. CONCLUSION Variations in predictors of iron deficiency or iron deficiency anemia according to iron supplementation suggest that direct comparisons across studies are tenuous at best without data on early iron status and certainty that specific conditions are comparable.

Abstract
BACKGROUND The growth, development and nutrition of children in Tibet with high-altitude and unique traditional culture have recently gained attention. However, few researches are available on the nutritional status of younger children of Tibet. OBJECTIVE The objective of the study was to evaluate the nutritional status of children below 36 months old in Tibet by means of anthropometry. DESIGN The cross-sectional survey was conducted between August and September in 1999 and a sample of 1655 children below 36 months old was obtained using a stratified multistage cluster random sampling method from a total of seven districts of Tibet. Height, weight and hemoglobin concentration were measured and at the same time related sociodemographic and environmental information were collected. NCHS/CDC/WHO reference data were used to evaluate the nutritional status of the entire study children population and estimate the prevalence of stunting, underweight and wasting. RESULTS Compared with the reference of NCHS/CDC/WHO, the distributions of HAZ and WAZ shifted to the left significantly and the means of HAZ and WAZ were -1.53 and -1.05, respectively, which were significantly lower than the reference value. The distribution of WHZ, however, was close to that of the reference. The reduction of Z-scores for height and weight occurred very early in life and was greatest in the second year after birth. The prevalence of malnutrition of children was 39.0% for stunting, 23.7% for underweight and 5.6% for wasting, respectively. Rural children had prevalence of stunting of 41.4% and underweight of 24.7%, as compared with prevalence of stunting of 25.3% and underweight of 18.1% for urban children. Stunting and underweight were associated with altitudes. The mean of hemoglobin (Hb) of children was 120.4 g/l and rural children had a significantly lower Hb concentration (119.9 g/l) than urban children (123.3 g/l). The prevalence of anemia seemed higher when using different altitude corrections for Hb to estimate the prevalence, but the consequences were uneven. CONCLUSIONS For Tibetan young children, the nutritional status of the entire population is poor and the prevalence of malnutrition is higher, especially for stunting. Malnutrition is related to high altitudes. Although the Hb concentration is higher induced by high altitude, there must be quite a lot of anemic children at high altitudes. The relationship between altitude and Hb for children on the Tibetan plateau requires further study in order to determine correctly the magnitude of anemia of children.

Abstract
BACKGROUND Intervention trials have shown that zinc may be efficacious in treating acute diarrhea in children of developing countries. A double-blind placebo-controlled study was designed to evaluate the effects of zinc supplementation on the clinical course and duration of diarrhea in malnourished Turkish children. METHODS The study group comprised 40 subjects with low zinc levels (Group 1a) and 52 subjects with normal zinc levels (Group 1b). The control group was also comprised of two subgroups: 36 subjects with low zinc levels (Group 2a) and 54 subject with normal zinc levels (Group 2b). Forty-three percent of children in the study group and 40% of controls had low serum zinc levels (<14 micromol/L), and 43% of subjects in both groups had very low serum zinc concentrations (<10 micromol/L). The study group were given 20 mg zinc per day for 10 days and the control group were given 750 mg glucose per day as a placebo for 10 days. RESULTS The mean duration of diarrhea was shorter and the percentage of children with consistent diarrhea for more than 3-7 days was lower in the study subgroups than in the control subgroups. Prolonged diarrhea was present in 12% of children in the study group, and in 44% and 37% of children in the hypozincemic and normozincemic control subgroups, respectively. The was no significant difference among the four subgroups of children in the number of cases with post-enrollment diarrhea of a duration of>14 days. Stool frequency over the first 4 days after enrollment was lower in children in the study group. CONCLUSION It was concluded that zinc supplementation in malnourished children with acute diarrhea may reduce the severity and duration of diarrhea, especially in children with low zinc levels.

Abstract
OBJECTIVE To verify the influence of Low Birthweight (LBW) on child anemia and malnutrition during the first year of life. METHODS Sample population included all children under one year seen at Health Units of the municipality of Maringá, southern Brazil, in 1998. Total sample size was 587 children. LBW was defined as birthweight below 2 500 g. The analysis of growth for the weigh-for-age and height-for-age indicators was based on National Center for Health Statistics standards. For anemia diagnosis, a biochemical hemoglobin concentration dosage, using HemoCue direct colorimetric method was employed. Children with [Hb] <11,0 g/dL were considered as anemic. RESULTS Fifty-eight percent of the studied population were anemic, and 37 children (6.3%) presented LBW. Anemia was more prevalent during the second semester of life (p=0.0093). Undernutrition, as indicated by the height-for-age indicator, was high especially for children aged 0-3 months with LBW. CONCLUSIONS Although LBW rates among the studied population were similar to those of developed countries, we suggest the implementation of specific antenatal care for high-risk women, aiming at reducing LBW, an event that affects the child, hampering its growth and increasing the risk of anemia and its countless deleterious consequences.

Abstract
OBJECTIVE To determine the prevalence of hypovitaminosis D in exclusively breast-feeding infants and their mothers in a community where maternal sunshine exposure is low. STUDY DESIGN Serum levels of calcium, phosphate, alkaline phosphatase, 25-hydroxy vitamin D (25-OHD), and intact parathyroid hormone were measured in 90 unsupplemented healthy term breast-feeding Arab/South Asian infants and their mothers in summer. Maternal dietary vitamin D intake was also estimated. RESULTS The median age of infants was 6 weeks. The median serum 25-OHD concentrations in mothers (8.6 ng/mL) and infants (4.6 ng/mL) were low, and 61% of the mothers and 82% of the 78 infants tested had hypovitaminosis D (serum 25-OHD <10 ng/mL). The infants with hypovitaminosis D had elevated serum alkaline phosphatase and a tendency to higher serum intact parathyroid hormone levels. The average daily maternal vitamin D intake from commercial milk was 88 IU. CONCLUSIONS Hypovitaminosis D is common in summer in exclusively breast-feeding infants and their mothers. The results provide justification for vitamin D supplementation of breast-feeding infants and mothers in the United Arab Emirates. Low vitamin D intake probably contributed to low maternal vitamin D status.

Abstract
OBJECTIVE To estimate the prevalence of stunting, wasting and anaemia among children aged 6-59 months in the Kzyl-Orda region of Kazakhstan, and to determine the association between childhood height and haemoglobin concentration and a range of environmental and biological factors. DESIGN A cross-sectional study using a randomly selected sample. The mothers of children were interviewed, and finger-prick blood samples and anthropometric measurements were collected on both mothers and their children. Associations between haemoglobin (Hb) concentration, anthropometric measurements and questionnaire data were evaluated by multivariate analysis. SETTING Health centres in Kazalinsk, Djalagash and Zhanakorgan districts of Kzyl-Orda region, Kazakhstan. SUBJECTS Two-thousand and twenty-four children aged between 6 and 59 months born to 1501 mothers who were randomly selected from health centre records. RESULTS The overall prevalence of stunting (<-2.0 Z-scores height for age), wasting (<-2.0 Z-scores weight for height) and anaemia (Hb<11.0 g/dl) in the study children was found to be 15.8, 0.8 and 50.1%, respectively. However, analysis demonstrated considerable variation by age, with the second year of life showing the highest prevalence of both stunting and anaemia. Both childhood height and haemoglobin concentration were found to be significantly associated with a range of environmental and maternal variables. CONCLUSIONS This study demonstrates that the prevalence of both stunting and anaemia among Kazakh children in the Kzyl-Orda region is considerable, and similar to that of other Central Asian children. These findings highlight Central Asia as a region with levels of childhood nutritional status that are of concern.

Abstract
Serial anthropometry and assay of plasma iron (Fe), zinc (Zn) and copper (Cu) were done on 72 babies with birth asphyxia during the first six months of life to assess the pattern of their physical growth and trace element status, respectively. Eighty-seven non-asphyxiated babies served as controls. The mothers of babies in both groups also had their plasma assayed for Fe, Zn and Cu immediately following delivery. Asphyxiated babies were lighter than non-asphyxiated controls during the first two months of life and they also had smaller mean occipito-frontal circumference at birth. While Fe, Zn and Cu status was generally comparable in both groups, the newborn Cu concentrations were very low compared with earlier reports. No baby showed any overt signs of trace element deficiency.

Abstract
OBJECTIVES To determine the nutritional and health status of urban infants in two disadvantaged communities in the Western Cape, South Africa with special reference to micronutrient status. The results of this study will serve to plan an intervention study in these communities in the same age group. DESIGN Cross-sectional study. SETTING Two disadvantaged urban black and 'coloured' communities in the Western Cape, South Africa. SUBJECTS Sixty infants aged 6-12 months from each community. OUTCOME MEASURES Dietary intake, anthropometric measurements, micronutrient status and psychomotor development. RESULTS Stunting and underweight were more prevalent in coloured infants (18% and 7%, respectively) than in black infants (8% and 2%, respectively). Anaemia (haemoglobin (Hb) < 11 g dl(-1) was prevalent in 64% of coloured and 83% of black infants. Iron-deficiency anaemia (Hb < 11 g dl(-1) and ferritin < 10 ng ml(-1) was found in 32% of coloured infants and in 46% of black infants. Zinc deficiency was prevalent in 35% and 33% of the coloured and black infants, respectively. Marginal vitamin A deficiency (serum retinol < 20 microg dl(-1) was observed in 23% of black infants compared with 2% of coloured infants. Of black infants, 43% and of coloured infants 6% were deficient in two or more micronutrients. Six per cent of coloured infants had C-reactive protein concentrations above 5 mg l(-1) compared with 38% of the black infants. The dietary intake of micronutrients was in general lower in black infants than in coloured infants. The overall psychomotor development, assessed by the Denver Developmental Screening Test, was different between the two groups. The coloured infants scored higher in three out of the four categories as well as in their overall score. CONCLUSIONS This study shows that information on stunting and wasting only in urban disadvantaged infants is not sufficient to make recommendations about specific community intervention programmes. Information on the micronutrient status, independent of wasting and stunting, is necessary to design nutrition programmes for different communities. The study also showed a substantially higher prevalence of micronutrient deficiencies among black infants.

Abstract
Hematological parameters and the iron status of 50 randomly selected infants who were attending the research infant welfare clinic of the Institute of Child Health, Ibadan (ICHI), for routine immunization were studied. Investigations included estimations of packed cell volume (PCV), haemoglobin (Hb), serum iron (Fe), unsaturated iron-binding capacity (UIBC) and total iron-binding Capacity (TIBC). Forty percent of the infants had PCVs below 0.32, 48% had Hbs below 10 g/dl and 27% had mean corpuscular volume (MVC) less that 70fl. Thirty-seven percent of the children had serum Fe below 3.58 mmol/l, but only 4% had UIBC above 320 mmol/l. Fifty-two percent had Transferin Saturation Index (TSI) below 10%. Eighteen percent had MCV below 70fl associated with TSI below 10% and 67% of these had Hbs below 10 g/dl. The prevalence of iron deficiency anaemia in infants as shown in this study is very high. The ill effects of iron deficiency in childhood have been well documented. It is suggested that screening for anaemia should be offered at 9 months as part of a Child Survival Programme and that infants found to be anaemic should be treated. However, for cost-effectiveness and taking into consideration the high prevalence rate of iron deficiency in this age group, it might be preferable to give iron and weekly prophylactic antimalarias routinely to infants aged 9 to 15 months in lieu of screening.

Abstract
OBJECTIVE To explore relationships between malnutrition and pancreatic damage in hospitalised aboriginal children. METHODS Immunoreactive trypsinogen (IRT) concentrations were measured in two populations of hospitalised aboriginal children in Australia: 472 children aged 0-3 years, in Alice Springs (Northern Territory); and 187 children aged 0-16 years in Mount Isa (Queensland). Correlation of whole blood IRT with height and weight z-scores, four-site skinfold thickness and upper arm circumference was sought. RESULTS In Mount Isa, the geometric mean IRT concentration rose with decreasing weight z-score. The IRT concentration was otherwise unrelated to nutritional indices. Sixty percent of the 39 Mount Isa patients with gastroenteritis and 24.5% of the 358 Alice Springs patients with gastroenteritis had an IRT concentration in the upper quartile for their population, compared with 16% for patients with other diagnoses in both populations. CONCLUSIONS A high IRT concentration in patients with low weight z-scores is a confounding effect of gastroenteritis, and may result from subclinical pancreatic disease in gastroenteritis.

Abstract
Erythrocyte fatty acids and plasma vitamin E concentrations were determined in 47 grade 2 and 21 grade 3 malnourished Pakistani children (ages 4-56 months). Data were compared with those of 26 age- and sex-matched apparently healthy controls. Evaluation with three statistical approaches revealed that both grade 2 and grade 3 malnourished children had decreased erythrocyte omega6 fatty acids and to a lesser extent decreased omega3 fatty acids. These decreases were compensated for by increased omega9 fatty acids. The patients tended to have lower plasma vitamin E concentrations. We conclude that malnourished Pakistani children have low essential fatty acid status, notably those of the omega6 series. The combination of low erythrocyte 22:6omega3 and a low 22:5omega6/22:4omega6 ratio in grade 2 patients suggests low delta4-desaturation activity, which may be due to impaired peroxisomal beta-oxidation.

Abstract
Mild, growth-limiting zinc deficiency might be prevalent in otherwise healthy infants according to recent studies. We examined zinc intake and status in 91 healthy term infants from birth to 12 months, as part of the Copenhagen Cohort Study on Infant Nutrition and Growth. Zinc intake was recorded monthly and the amount of zinc absorbed was estimated. These estimates were below recently published FAO/WHO/IAEA values for basal requirements in 68%, 62% and 14% of the infants at 2, 4 and 9 months of age, respectively. Serum zinc decreased significantly (p < 0.01) from 10.6 mumol/l at 6 months to 8.4 mumol/l at 9 months of age (normal range 10-18 mumol/l). Erythrocyte metallothionein values, a tentative indicator of long-term zinc status, decreased significantly from 2 to 6 months (p < 0.001) and from 6 to 9 months (p < 0.01). Serum zinc at 9 months was positively associated with growth velocity during the period from 6 to 9 months (weight: p = 0.05; knee-heel length: p = 0.002). The results provide descriptive data on zinc intake and zinc status in healthy Danish infants. Although some of our data suggest suboptimal zinc status during late infancy, evidence for this can only be obtained through a randomized intervention study.

Abstract
A pair-matched controlled study was done with 30 children (15 males, 15 females) of mild to moderate PEM in test and equal number in control groups, aged 8-24 months old. At the beginning, in both test and control groups parents were advised to provide sufficient amount of home cooked foods so that the child received on an average 100-150 Kcal/kg/day of energy and 2-3 g/kg/day of protein. Vitamin supplements were provided to all children in both groups. In addition, the test group received a supplementation of 5.625 mg of elemental zinc daily orally while controls received a placebo. Evaluation at the end of 3 months showed that children in test group had a weight gain of 3.742 +/- 0.488 kg against 2.035 +/- 0.383 kg of the control group. Similarly, weight velocity was 5.752 +/- 0.818 g/kg/day in test group against 3.153 +/- 0.617 g/kg/day of the control group. These differences in weight gain and weight velocity were highly significant (p < 0.001). Serum zinc levels, initially and at the end of study were 87.5 +/- 9.6 micrograms/dl and 121.0 +/- 10.1 micrograms/dl, respectively in test group in comparison to 91.2 +/- 9.8 micrograms/dl and 91.0 +/- 10.1 micrograms/dl in controls. This difference was also highly significant (p < 0.001). The daily total calorie intake remained comparable in both groups. Our observations suggest that zinc supplementation during nutritional rehabilitation of mild to moderate PEM hastens the recovery.

Abstract
Babies who are small at birth or during infancy have increased rates of cardiovascular disease and non-insulin-dependent diabetes as adults. Some of these babies have low birthweights, some are small in relation to the size of their placentas, some are thin at birth, and some are short at birth and fail to gain weight in infancy. This paper shows how fetal undernutrition at different stages of gestation can be linked to these patterns of early growth. The fetuses' adaptations to undernutrition are associated with changes in the concentrations of fetal and placental hormones. Persisting changes in the levels of hormone secretion, and in the sensitivity of tissues to them, may link fetal undernutrition with abnormal structure, function, and disease in adult life.

Abstract
Haptoglobin, transferrin, alpha-1-feto-protein (AFP), alpha-1-acid glycoprotein (AAGP) and caeruloplasmin levels were estimated in 14 "small for dates" (SFD) and 31 "appropriate for dates" (AFD) babies by the single radial immunodiffusion method. The mean caeruloplasmin levels was observed to be significantly reduced in the SFD babies when compared with the AFD babies (t = 3.4582, P < 0.02). None of the other 4 acute phase proteins showed any significant differences in mean concentration between the SFD babies and the controls. The diminished caeruloplasmin levels observed in SFD babies agrees with previous reports in post-natal undernutrition. Our findings of no significant differences in the other 4 acute phase proteins between SFD and AFD babies are however at variance with previous observations of elevated levels of AFP, haptoglobin and AAGP and reduced levels of transferrin in malnourished infants.

Abstract
We investigated the serum manganese (Mn) concentration of 52 children less than two years old. 22 of them were healthy controls (C), 13 had marasmatic (M) malnutrition and 17 kwashiorkor (K). The measurements of Mn were done in an atomic absorption spectrophotometer with a graft furnace oven. The serum was diluted with 1% triton X-100. For the quantification of Mn we used the addition method. There was a significant difference between the levels of Mn measured in the M group (1,582 +/- 0.673 micrograms/L), and the K group (1,811 +/- 0.700 micrograms/L) and levels obtained in the controls (3,212 +/- 1,247 micrograms/L). When we compared the concentration of Mn by sex or age in each group, we didn't find any significant difference. We conclude that the severe malnourished children in our study present lower concentrations of Mn as compared with controls.

Abstract
We investigated the fat-soluble-vitamin status during the first year of life in 36 infants with cystic fibrosis (CF) consecutively identified by screening of newborns. At initial evaluation (at age 51.0 +/- 26.7 d) 36% of patients were hypoalbuminemic, 21% had low serum retinol, 35% had low serum 25-hydroxyvitamin D. 38% had low serum alpha-tocopherol and low ratios of serum vitamin E to total lipids, and none had elevated protein in vitamin K absence (PIVKA). Hypoalbuminemia was more common in breast-fed than in formula-fed infants. Seventy-two-hour fecal fat excretion correlated inversely with serum alpha-tocopherol. Treatment with oral pancreatic enzyme supplements, a multiple vitamin, and additional vitamin E was associated with normalization of serum albumin, retinol, and 25-hydroxyvitamin D and negative PIVKA at age 6 and 12 mo. Approximately 10% of patients remained vitamin E deficient. Biochemical evidence of fat-soluble-vitamin deficiencies is common before age 3 mo in patients with CF and, except for vitamin E, these deficiencies corrected with standard therapy.

Abstract
Zinc deficiency occurs as a genetic disorder, acrodermatitis enteropathica, or as an acquired disorder resulting from inadequate intake or malabsorption of zinc. It is now apparent that human breast milk may not always protect against the development of clinical zinc deficiency in premature and in full-term infants. In the absence of other predisposing factors, low levels of zinc in breast milk may precipitate zinc deficiency in breast-fed infants. This report confirms that breast-fed full-term infants may develop a clinical picture indistinguishable from acrodermatitis enteropathica.

Abstract
Plasma prealbumin (PA) and retinol-binding protein (RBP) concentrations were serially measured in 25 critically ill, malnourished infants requiring parenteral nutrition to determine if these visceral protein markers are useful in assessing acute protein repletion. Significant increases in both proteins (p less than 0.05) were noted as early as 5 to 7 days after institution of parenteral nutrition and continued significantly above baseline values through 2 weeks of observation. Gestational development (in infants less than 4 weeks old) and mean protein intake influenced visceral protein responses. Appropriate for gestational age neonates had more rapid and quantitatively greater PA responses (p less than 0.05) than small for gestational age neonates. Small for gestational age neonates never exceeded baseline RBP responses. Average protein intake of less than or equal to 2 g/kg/day resulted in PA and RBP concentrations below baseline and significantly lower than infants on higher protein intakes (p less than 0.05), at the end of 2 weeks. Average calorie intake of greater than 100 cal/kg/day had no differential influence on PA or RBP when compared with infants on less calories. Prealbumin values correlated with RBP values observed simultaneously (r = 0.588, p less than 0.0001). We conclude that PA and RBP are useful measures of protein repletion in critically ill infants requiring parenteral nutrition.

Abstract
The fatty acid (FA) composition of the main plasma lipids was analysed in eight well-nourished, generally healthy Nigerian children aged 14.1 +/- 7.2 months and in 17 malnourished children (8 marasmus, 9 kwashiorkor) aged 14.6 +/- 3.8 months within the first 2 days of admission at the Dept. of Child Health, University of Benin. In comparison to the control group, the malnourished children showed a marked decrease of polyunsaturated FA with low linoleic acid, mainly in sterol esters (STE), and severely reduced linoleic acid metabolites, including arachidonic acid, in all lipid fractions. omega-3-FA were not altered except for a reduction of docosapentaenoic and docosahexaenoic acids in phospholipids. Clearly increased values were found for saturated FA in STE and for the non-essential monoenoic FA in all lipid classes. This pattern indicates the presence of essential fatty acid deficiency in the malnourished children. There was no significant difference between marasmus and kwashiorkor. Eight malnourished children were followed up in the early phase of recovery during hospital treatment 14.0 +/- 3.1 days after obtaining the first sample. Linoleic acid had increased again in STE, but its metabolites were as low or even lower than before. An impaired activity of delta-6-desaturase, the rate limiting enzyme of linoleic acid metabolism, in suggested by elevated substrate-product-ratios of this enzyme in untreated children with protein energy malnutrition and in the early phase of recovery, which may be due to low insulin levels, protein and zinc deficiency. The trientetraen ratio (20:3 omega 9/20:4 omega 6) thus is not a reliable indicator of essential FA status in protein-energy malnutrition.

Abstract
The lipid metabolism and acetylating processes were studied in children with chronic nutritional disorders during their treatment. In dystrophic children significant shifts in lipid metabolism were recorded: the levels of chylomicronemia, phospholipids, total lipids decreased, while those of free fatty acids and total cholesterol increased. The coenzyme acetylating processes in the patients with nutritional disorders were also impaired. The management of dystrophic patients was attended by a progressive recovery of the lipid metabolism. The elucidation of the pathogenesis of metabolic disorders in dystrophic children would permit outlining the ways for their dietetic and drug correction.

Abstract
Thyroxine-binding prealbumin (TBPA) appears as a sensitive blood parameter for assessing various forms of protein and calorie malnutrition, ranging for subclinical protein deficit to frank kwashiorkor. More precisely, TBPA serves as a valid marker for determining both protein nutritional adequacy and the optimal ratio of energy and zinc to nitrogen intake in healthy newborns and preterm infants without infection. When inflammation is present, the decrease in TBPA blood levels reflects a deterioration in the patient's condition and its increase monitors the efficacy of dietary management. In this latter inflammatory context, it is recommended to combine the measurement of TBPA with that of the most reliable indicators of the phlogistic reaction, allowing the discrimination of both infectious and nutritional poles of the disease spectrum.

Abstract
A sample of 1326 new-born babies has been studied regarding the influence of the milk diet over some plasma-serum amino acids. The Authors have make use of the screening of the congenital errors of the protein metabolism. New-born babies were bled on the fifth or sixth day of life and their blood was analysed at first with the Guthrie test and then with automatic chromatographic determination. New-born babies have been arranged according to their gestational age, birth weight and intrauterine growth. More then 90% of the sample was formed by normal for gestational age new-born babies. We have make use of five different milk formulas: a mixed one (human milk with adapted milks), three powdered milks with three different casein-serum proteins ratio and finally cow's milk with 50% water. The best formula among these ones has been the human milk mixed with adapted milks. The completely artificial formulas, but with casein/serum proteins ratio lower or equal to one, has given rise to a few amino acid alterations, too. On the contrary, the cow's milk mixed with water and the artificial powdered milks with a casein-serum proteins ratio equal to 4.5 shouldn't be utilized in the new-born baby's diet, as they may provoke remarkable alteration in the amino acid metabolism.

Plasma and red cell fatty acids were measured in 44 children with third degree malnutrition: 22 children with marasmus, 11 children with kwashiorkor, and 11 with marasmic kwashiorkor (MK). The presence of edema, dermatosis, hair changes, and hypoalbuminemia were positively correlated with the red cell percentage linoleic acid and negatively correlated with red cell percentage arachidonic acid. Red cell percentage linoleic acid in kwashiorkor was decreased from the control value of 15.3% to 10.9%. In marasmus and MK, there were significantly greater decreases, to 7.7% and 8.0%, respectively. Red cell arachidonic acid in kwashiorkor was significantly (P less than 0.001) decreased to 9.8% (control value of 13.1%) whereas in marasmus there was no significant change. Only one sample, plasma from an infant with marasmus, had any detectable eicosatrienoic acid (20:3,omega 9). Similar changes in fatty acid composition have been reported in infants with acrodermatitis enteropathica, in an infant with biotin deficiency, and in biotin-deficient rats.

Abstract
Two newborn infants receiving long-term, fat-free parenteral nutrition developed essential fatty acid (EFA) deficiency. Biochemical evidence of EFA deficiency was documented in plasma, red blood cells, and adipose tissue and included a decrease in arachidonic and linoleic acids, an increase in 5,8,11-eicosatrienoic acid, palmitoleic and oleic acids and a trienoic/tetraenoic ratio of more than 0.4. Cutaneous application of sunflower-seed oil, a source rich in the essential fat linoleic acid, rapidly reversed the clinical and biochemical manifestations of deficiency in plasma.

Abstract
To study the effect of fat-free alimentation on essential fatty acids (EFA), their levels in plasma phospholipids, cholesterol esters, triglycerides, and free fatty acids were measured in five sick newborns. Four patients were under 32 weeks of gestation; three were small for gestational age and one was an infant of a diabetic mother. All developed biochemical evidence of EFA deficiency during the first week of life--the smallest infant did so by the second day. Biochemical evidence of EFA deficiency included a decrease in plasma lipid arachidonic and linoleic acids, an increase in 5,8,11-eicosatrienoic acid, palmitoleic, and oleic acids and a trienoic/tetraenoic ratio of more than 0.4. Oral feeding with EFA reversed these changes. The two infants showing the most severe biochemical evidence of EFA deficiency died. Neither exchange transfusion nor multiple blood transfusions prevented or corrected the development of EFA deficiency. An alternative method for efficient and safe delivery of EFA to such infants is required.
