The highest prevalence of anemia exists in the developing world where its causes are multi-factorial. Anemia is responsible for significant morbidity and mortality, particularly in less developed countries (LDCs). Understanding causes of anemia and potential mechanisms are crucial to our ability to intervene to reduce this burden. In the past ...

Due to the insidious nature of infant anaemia, this disorder frequently remains undetected and untreated by health-care workers in resource-poor settings. We assessed the accuracy of a low-cost and simple diagnostic tool, the haemoglobin colour scale (HCS), in estimating haemoglobin (Hb) values in infants between zero and four months of ...

AIM: We aimed to develop policy in relation to three areas: (i) the diagnosis of iron deficiency; (ii) maternal-infant issues and the prevention of iron deficiency; and (iii) the treatment of iron deficiency.

The iron-clearing efficiency (ICE) in rodents and primates ...

Zinc deficiency occurs in children when the demand for zinc exceeds its supply. Malnutrition, prematurity, total parenteral nutrition dependence, and burns increase the demand for zinc, whereas congenital malabsorption syndromes represent clinical situations where less zinc is supplied to the growing child. Clinical recognition of acral eczematous lesions, alopecia, and ...

To evaluate effects of Fe supplementation and sex on the prevalence of anaemia and Fe status in infants in South-East Asia, biochemical data from four parallel, randomized, double-blind trials with Fe and/or Zn supplementation in infants (n 2452) in Indonesia, Thailand and Vietnam was pooled. At recruitment (5 months of ...

A newborn boy with family history of severe ornithine transcarbamylase (OTC) deficiency was investigated prospectively and managed aggressively at birth based on an existing protocol for at risk neonates. Undetectable citrulline levels at birth suggested that the infant was affected; however, normal plasma glutamine and urine orotic acid levels confused ...

Sensitive periods for induction of behavioral impairments by developmental iron deficiency were studied in a nonhuman primate model. Rhesus monkey infants were deprived of iron prenatally (n = 14) via the dam's diet (10 microg Fe/g) or postnatally (birth-4 mo, n = 12) via infant formula (1.5 mg Fe/L). They ...

Four hundred and forty-five randomly selected hospitalised patients had their nutritional status assessed from anthropometric, haematological and biochemical data.

METHODS: We evaluated sTfR as an indicator of iron deficiency in 134 HIV-infected 9-month-old infants in ...

Exclusive breastfeeding for the first 6 mo of life followed by optimal complementary feeding are critical public health measures for reducing and preventing morbidity and mortality in young children. Clinical factors, such as birth weight, prematurity, and illness, that affect the iron and zinc requirements of younger infants are discussed. ...

Infants are at risk for iron deficiency as breast milk or formula is replaced by semisolid foods during weaning. The scope of this article is to briefly review new findings on developmental iron deficiency and the persistence of deficiency effects into adulthood. A lack of sufficient iron intake may significantly ...

The complementary feeding period is a critical stage for growth and development. Infants in developing countries and selected individuals in developed countries may benefit from micronutrient supplementation, but long-term effects are still poorly explored. We have some evidence, coming from observational studies, of the role of iron in the second ...

Serum ferritin measurements are used in clinical populations to estimate total body iron stores and the risk of subsequent iron deficiency or overload. The lack of normative newborn serum ferritin concentration data between 23 and 41 weeks has led to difficulty in establishing the incidence and degree of abnormal iron ...

Borrelia burgdorferi survives in an enzootic cycle, and Dps proteins protect DNA against damage during starvation or oxidative stress. The role of a Dps homologue encoded by Borrelia in spirochaete survival was assessed. Dps-deficient spirochaetes were infectious in mice via needle-inoculation at the dose of 10(5) spirochaetes. Larval ticks successfully ...

Both iron deficiency and iron excess during the fetal and neonatal period bode poorly for developing organ systems. Maternal conditions such as iron deficiency, diabetes mellitus, hypertension and smoking, and preterm birth are the common causes of perinatal iron deficiency. Long-term neurodevelopmental impairments and predisposition to future iron deficiency that ...

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. The objectives of the study were to apply a physiologic model to identify risk factors for iron deficiency and to consider those risk factors ...

Neutrophil dysfunction can result from oxidative burst defect or from glucose-6-phosphate dehydrogenase (G6PD) deficiency; we noted both in the same patient. A 4-month-old male infant with G6PD deficiency presented with swelling of the left middle finger, left leg, and right big toe. At 5 weeks of age he was hospitalized ...

We report ten infants (mean gestational age: 30 weeks; range: 25 to 40 weeks) with zinc deficiency dermatitis who developed erosive, impetiginized periorificial dermatitis at 10 weeks of age (corresponding to a mean gestational age of 41.4 weeks, with a range of 36-44 weeks), but who were otherwise well. Cutaneous ...

Iron deficiency (ID) is common in pregnant women and infants worldwide. Rodent models show that ID during gestation/lactation alters neurometabolism, neurotransmitters, myelination, and gene/protein profiles before and after iron repletion at weaning. Human infants with iron deficiency anemia test lower in cognitive, motor, social-emotional, and neurophysiologic development than comparison group ...

Iron deficiency is prevalent in children and infants worldwide. Zinc deficiency may be prevalent, but data are lacking. Both iron and zinc deficiency negatively affect growth and psychomotor development. Combined iron and zinc supplementation might be beneficial, but the potential interactions need to be verified. In a randomized, placebo-controlled trial ...

Iron absorption in adults is regulated by homeostatic mechanisms that decrease absorption when iron status is high. There are few data, however, regarding the existence of a similar homeostatic regulation in infants. We studied 2 groups of human milk-fed infants using (57)Fe (given as ferrous sulfate without any milk) and ...

Iron deficiency is the most common micronutrient deficiency during pregnancy, and maternal anemia has been associated with poor pregnancy outcomes. However, it is still not clear how directly maternal iron status is linked to the infant's iron status postpartum. We investigated the impact of maternal iron deficiency on the hematological ...

Phthalate dioxygenase (PDO) and its reductase are parts of a two-component Rieske dioxygenase system that initiates the aerobic breakdown of phthalate by forming cis-4,5-dihydro-4,5-dihydroxyphthalate (DHD). Aspartate D178 in PDO, located near its ferrous mononuclear center, is highly conserved among Rieske dioxygenases. The analogous aspartate has been implicated in electron transfer ...
