OBJECTIVES: To understand lay views on infant size and growth and their implications for a British population. METHODS: A systematic review of parental and other lay views about the meanings and importance of infant size and growth using Medline, PsycInfo, CINAHL, Sociological Abstracts, IBSS, ASSIA, British Nursing Index ChildData, Caredata, ...

OBJECTIVE: To describe growth of prematurely born infants and create a growth chart adequate to assess growth of infants with less than 29 completed weeks of gestation. STUDY DESIGN: Birth weight, head circumference and length measurements of 7,425 liveborn preterm infants from 1985 to 1997 were retrieved from a longitudinal ...

BACKGROUND: It is known that extremely premature infants do less well than more mature infants, and this fact has led some countries to adopt a "cutoff for viability" using birth weight or gestation. Infants affected by intrauterine growth retardation are at additional risk of poor outcome. There are few data ...

The distribution and quantity of adipose tissue are markers of morbidity risk in children and adults. Poor intrauterine growth and accelerated postnatal growth are believed to add to these risks. The aim of this study was to assess adipose tissue content and distribution at birth and 6 wk in relation ...

BACKGROUND: Slower rates of infant growth are associated with increased rates of death from ischaemic heart disease (IHD) in later life. We carried out a systematic review to assess the association between infant size or growth and leading causes of adult burden of disease to contribute to the debate on ...

This study was carried out to build statistical models for defining FGR (Fetal Growth Restriction) in weight and/or length after taking growth potential of an infant into account. From a cohort of pregnant women having given birth to 47,733 infants in 141 French maternity units, two statistical models gave individualized ...

Normal fetal nutrition is a useful guide for understanding postnatal nutrition of infants born very preterm. Fetal lipid uptake gradually increases towards term and is primarily used to produce fat in adipose tissue, with essential fatty acid uptake providing necessary structural and functional elements in membranes of cells in the ...

Measurement of aerodigestive tract length is an important determinant for accurate placement of esophageal probes and gavage tubes at the desired location. The relationship of esophageal body, upper esophageal sphincter (UES) and lower esophageal sphincter (LES) lengths with somatic growth in neonates is not well understood. Our objectives were to ...

Inadequate supply of one or more mineral elements can slow the growth of animal consumers and alter their physiology, life history and behaviour. A key concept for understanding nutrient deficiency in animals is the threshold elemental ratio (TER), at which growth limitation switches from one element to another. We used ...

Uteroplacental vascular insufficiency in humans is a common cause of intrauterine growth restriction (IUGR) and is associated with an increased incidence of perinatal asphyxia and neurodevelopmental disorders compared to normal weight newborns. Experimental models that provide an opportunity to analyze the pathogenesis of these relationships are limited. Here, we used ...

OBJECTIVE: We developed a fetal growth risk curve that delineates the birth weight values for gestational age that reflect a 2-, 2.5-, and 3-fold neonatal death risk relative to infants with normal fetal growth. STUDY DESIGN: We analyzed 18,085,052 single gestation infants (25-42 weeks) who were born to US resident ...

Growth charts are used in pediatric medicine to plot anthropomorphic measurements over time, serving as a screen for diseases related to a patient's nutritional and general health status. Whereas reference data for term infants are available from the Center for Disease Control, reference data for premature infants in a neonatal ...

This chapter reviews outcomes for children who have intrauterine growth retardation (IUGR) or small-for-gestation-age (SGA) status at birth. Such infants are at risk for increased perinatal mortality, birth adaptation complications, including perinatal acidosis, hypoglycemia, hypothermia, coagulation abnormalities, and selected immunologic deficiencies. IUGR infants also appear to be at great risk ...

OBJECTIVE: The aims were to examine the long-term functional outcome and risk of mood disorders in adulthood in individuals with foetal growth retardation. METHOD: In a prospective cohort study of 7806 individuals aged 20-30 years, using linked data from the Health Survey of Nord-Trøndelag (HUNT-2) and the Medical Birth Registry ...

BACKGROUND: We hypothesized that in premature infants, retinal vascular growth retardation between birth and postmenstrual age of approximately 30 to 32 weeks that initiates retinopathy of prematurity is paralleled by brain growth retardation. METHODS: In a prospective longitudinal study, we measured postnatal head growth, retinopathy of prematurity stage, protein and ...

Lingual tumours are uncommon in infants and harmatomas are rarely reported. A 5-month-old boy presented with a growth on the dorsum of the tongue which had been present from birth. The growth produced no respiratory or feeding difficulties. It was confirmed to be a harmatoma after complete excision. There has ...

Normal endocrine function in utero and early in childhood influences later height and weight attainment. Polychlorinated biphenyls (PCBs) are persistent environmental contaminants with suspected endocrine-disrupting properties. PCBs may mimic or inhibit hormone and endocrine processes based in part on their structural configuration, with non-ortho-substituted PCBs having a coplanar orientation and ...

Nutrient-enriched diets for preterm infants after hospital discharge (preterm formula or postdischarge formula (PDF)) results in improved growth and these differences appear to persist beyond the period of nutrient intervention. The PDF diet effect is greatest in males, possibly reflecting their higher growth rates. The critical growth epoch appears to ...

OBJECTIVE: To delineate the frequency and clinical presentation of confined placental mosaicism (CPM) among newborns with idiopathic intrauterine growth restriction (IUGR) as compared to infants with appropriate fetal growth. METHODS: 70 newborns with IUGR (birth weight < 10%) were matched by maternal age (+/-5 years) and gestational age (+/-7 days) ...

BACKGROUND: Only a few studies have dealt with postnatal growth velocity of very low birthweight (VLBW) infants. OBJECTIVE: To analyse weight growth kinetics of VLBW infants from birth to over 2 years of age. PATIENTS: A total of 262 VLBW infants were selected; inaccurate estimate of gestational age, major congenital ...

OBJECTIVES: The objectives of this study were to assess whether (1) in-hospital growth velocity is predictive of neurodevelopmental and growth outcomes at 18 to 22 months' corrected age among extremely low birth weight (ELBW) infants and (2) in-hospital growth velocity contributes to these outcomes after controlling for confounding demographic and ...

This report describes a 4-month-old male with cholestasis, hypoglycemia, and short stature. Symptoms appeared since neonatal age with jaundice, hypoglycemia, neurologic manifestations, and later with short stature. Laboratory investigation was indicative for cholestasis. Further research indicated isolated growth hormone deficiency with accompanying optic nerve hypoplasia. Unexplained hypoglycemia and cholestasis in ...

OBJECTIVE: Preeclampsia, gestational hypertension, and unexplained intrauterine growth restriction may have similar determinants and consequences. In this study, we compared determinants and perinatal outcomes associated with these obstetric conditions. STUDY DESIGN: We analyzed 39,615 pregnancies (data from the WHO Antenatal Care Trial), of which 2.2% were complicated by preeclampsia, 7.0% ...

The main purpose of this review is to discuss associations between within-litter variation in birth weight, and preweaning survival and postnatal growth in the pig, as the basis for suggesting that the developmental competence of pigs born, as well as the size of the litter, need critical consideration. Extremes of ...

Face-open nanoboxes of lead telluride and selenide have been synthesized by a simple hydrothermal method. Nano- and microcrystals of various morphologies, including microflowers, semi-microflowers, cubic nanoparticles, etc., have also been observed at different synthesis conditions. Temperature, time, and concentrations of various reactants play a major role in controlling the morphology ...

Enterobacter sakazakii can be present, although in low levels, in dry powdered infant formulae, and it has been linked to cases of meningitis in neonates, especially those born prematurely. In order to prevent illness, product contamination at manufacture and during preparation, as well as growth after reconstitution, must be minimized ...

BACKGROUND AND OBJECTIVE: It has been suggested that fetal growth restriction (FGR) is associated with fetal maturation so that, compared with appropriately grown preterm infants, mortality and some neonatal morbidities may be reduced. The evidence for this is conflicting, and severe FGR has been shown to be harmful. In addition ...

AIMS: The ponderal index describes body proportionality at birth thus distinguishing symmetric from asymmetric growth restriction. We aimed to develop ponderal index percentiles for preterm and term neonates born in a European population. METHODS: Auxologic data were obtained from neonates born from January 1990 to December 1998 from the datasets ...

BACKGROUND: Early growth in very low birth weight (VLBW) infants has been found predictive of their later outcomes. This has led to increased interest in establishing measures to optimise such growth. In facilities without the resources required to undertake long-term audits for all the high risk infants they graduate, these ...

OBJECTIVE: To determine if postnatal growth failure exerts an adverse effect on subsequent growth and neurodevelopment. STUDY DESIGN: A secondary analysis of 1018 infants who were enrolled in a randomized, clinical trial of glutamine supplementation was performed to determine whether early provision of parenteral amino acids (AA) is associated with ...

BACKGROUND: There is agreement amongst most investigators now on the fact that growth, when measured over short periods, is an irregular and non-linear process. However, many aspects related to this process still remain controversial, for example, the continuity or discontinuity of the daily changes and the degree of existence of ...

Magnesium deficiency in pregnant women is frequently seen because of inadequate or low intake of magnesium. Magnesium deficiency during pregnancy can induce not only maternal and fetal nutritional problems, but also consequences that might last in offspring throughout life. Many epidemiological studies have shown that restricted fetal growth, i.e. intrauterine ...

Intrauterine growth retardation is associated with oligonephropathy and the risk of hypertension and renal disease in adulthood. Animal study data show that nephron density is directly related to protein nutrition status during nephrogenesis. Among infants born at low gestation, postnatal growth retardation and major deficits in energy and protein intake ...

Catch-up growth has been the subject of many studies, but whether and when infants born preterm and with low birth weight achieve normal size is controversial. One of the reasons for diverse results is likely to be the difference in how the infants' ages are calculated. The aim of this ...

AIM: To determine in a cohort of very-low-birthweight (VLBW) infants the incidence of postnatal growth failure and the influence of intrauterine growth and neonatal morbidities on the risk for severe postnatal growth failure (PNGF). METHODS: The study was based on analysis of data from the Israel Neonatal Network database on ...

Understanding the factors leading to inter-annual variation in recruitment of animals with complex life cycles is a key goal for ecology and the sustainable management of animal resources, such as fisheries. We used otolith microstructure to determine larval growth rates of post-larval King George whiting, Sillaginodes punctata, in seagrass beds ...

High-quality PbS nanocrystals were produced in multigram-scale quantities through a solventless, heterogeneous, and relatively green route. The heterogeneous nature of this reaction allows one to limit the diffusion in the system, allowing for unprecedented monodispersity and quality of the product demonstrated by a full-width at half-maximum of the photoluminescence peak ...

BACKGROUND: Poor growth after preterm birth, particularly poor head growth, is associated with impaired neurodevelopmental outcome. OBJECTIVE: To evaluate weight gain and head growth between birth and term in a contemporary cohort of preterm infants, taking into account breast milk intake and illness severity. METHODS: Subjects were inborn infants <or=32 ...

Intra-annual radial growth rates and durations in trees are reported to differ greatly in relation to species, site and environmental conditions. However, very similar dynamics of cambial activity and wood formation are observed in temperate and boreal zones. Here, we compared weekly xylem cell production and variation in stem circumference ...

AIM: To examine the association between maternal post-natal depression and infant growth. BACKGROUND: Infant growth has recently been shown, in two studies from South Asia, to be adversely affected by maternal depression in the early post-partum period. It is uncertain whether a similar association obtains in developing countries outside Asia. ...

Our objective was to determine whether classification of birth weight as small, average, or large for gestational age using published fetal growth curves is predictive of a term infant's risk of hypoglycemia. This prospective, descriptive study measured and plotted birth weight measurements on six published fetal growth curves to classify ...

BACKGROUND AND AIM: Low birth-weight is known to be associated with an increase in cardiovascular risk similar to that seen with major environmental risk factors, such as cigarette smoking or hypertension. Much epidemiological evidence has linked low birth-weight with hypertriglyceridaemia. METHOD: We measured aortic wall thickness by ultrasonography and lipid ...

OBJECTIVE: Traditional measure of postnatal growth failure assessment has poor discriminatory power for long-term outcomes. Our objective was to identify measure of postnatal growth failure associated with long-term outcome in preterm infants born at < 28 weeks' gestation. PATIENTS AND METHODS: Four measures of defining postnatal growth failure at 36 ...

There is considerable evidence to show that babies born prematurely have poor postnatal growth, and the more premature the baby, the greater the impairment is likely to be and the longer it will persist. Nutrition has been shown to play an important part in this, but adequate nutrition is difficult, ...

OBJECTIVE: Infant boys show a brief activation of their hypothalamic-pituitary-gonadal axis shortly after birth, the physiological significance of which is poorly understood. The objective of the study was to investigate the correlation between endogenous testosterone levels and penile size and growth. DESIGN: Prospective, longitudinal population-based study taking place at two ...

BACKGROUND: Angiopoietin-2, an angiogenic factor, causing destabilization and postnatal remodeling of blood vessels, is upregulated by hypoxia. We hypothesized that circulating Angiopoietin-2 levels might differ in intrauterine growth restricted and appropriate for gestational age fetuses and neonates, as the former have restricted growth and development and suffer from in utero ...

Accurate definition of small for gestational age (SGA) is essential for antenatal as well as postnatal care. SGA is associated with significant antenatal and postnatal pathology. The term, however, includes constitutional smallness, and it is essential to adjust for physiological variation in order to identify those babies who are pathologically ...

BACKGROUND: Evidence-based practice guidelines for aggressive nutritional intervention by using parenteral amino acids (AAs) and minimal enteral feeding (MEF) as early as the first day of life have not been tested for benefits to bone mass. OBJECTIVE: We investigated whether early introduction of parenteral AAs and MEF improves growth and ...

CONTEXT: There is inconsistent evidence that maternal 25-hydroxyvitamin D [25-(OH)D] deficiency may impair fetal growth. OBJECTIVE: The objective of the study was to examine the relationship between maternal 25-(OH)D and PTH concentrations at less than 16 and 28 wk gestation and offspring birth size. DESIGN: This was an observational study. ...
