    Natural selection conserves mechanisms allowing women to spontaneously abort gestations least likely to yield fit offspring. Small gestational size has been proposed as an indicator of fitness observable by maternal biology. Previous research suggests that exposure to ambient stress in utero results in more "culling" of small fetuses and therefore lower rates of small-for-gestational-age (SGA). However, African American women persistently have higher rates of SGA than non-Hispanic white women, despite experiencing more ambient stress. This paper tests whether attenuation of the stress response among highly stressed African American women, as suggested by the weathering hypothesis, may help to explain this apparent inconsistency. We apply time-series modeling to over 2 million African American and non-Hispanic white male term births in California over the period of January 1989 through December 2010. We test for the parabolic (i.e., "U" shaped) relationship, implied by an attenuated stress response, between unusually strong labor market contraction and the rate of SGA among African American term male infants, and a linear relationship among non-Hispanic whites. We find the hypothesized parabolic relationship among term male African American infants. As expected, we find a linear relationship between unexpected layoffs and the rate of SGA among term male non-Hispanic whites. These results are robust to sensitivity analyses. These results may help to explain the high rates of SGA among term male African American infants, despite greater maternal exposure to ambient stress during pregnancy.

    Few studies have examined the role that small for gestational age (SGA) status plays in postoperative outcomes for low-birth-weight (LBW) infants with congenital heart disease (CHD). This study aimed to examine the effect of SGA status, gestational and chronologic age, and weight on differences in morbidities and mortalities during the immediate postoperative hospitalization period. The charts of infants with CHD weighing less than 2.5 kg who underwent operative repair during the neonatal period between 2004 and 2011 were reviewed. Infants with an isolated patent ductus arteriosus were excluded from the study. Data on hospital morbidities and mortality before discharge were collected. The study identified 136 LBW infants with a diagnosis of CHD. Among the 74 infants who underwent surgery and had complete chart records, the SGA infants had a higher gestational age at birth (36.8 vs. 32.3 weeks; p < 0.0001). The SGA and non-SGA infants did not differ in terms of survival to discharge or immediate postoperative outcomes. A lower weight at surgery was significantly associated with an increased risk of postoperative infection. In contradistinction, an older postnatal age at surgery was associated with an increased risk of preoperative infection (p < 0.0001). Additionally, lower gestational age at birth was associated with home oxygen use, higher tracheostomy rates, and discharge with a gastrostomy tube. Small for gestational age status played no protective role in the outcome for LBW infants after primary surgery for CHD. A weight of 2.4 kg or greater at the time of surgery was associated with lower rates of postoperative infections. Greater duration of time between birth and surgery was associated with a greater risk of preoperative infection. A gestational age of 32 weeks or more at birth was associated with decreased morbidities, which could influence obstetric management. PMID:24997649

    We performed this study to longitudinally compare rates of stunting, wasting and underweight among low birthweight (LBW), non-LBW, and/or small-for-gestational age (SGA) and non-SGA infants in Leyte, The Philippines and factors that predicted catch up. Birthweights of 357 infants born in Leyte, The Philippines were obtained within 48 hours of delivery and infants were evaluated at one, six and 12 months. Newborns were classified as LBW, SGA, or both. We derived length-for-age, weight-for-length and weight-for-age Z-scores using WHOAnthro. Generalized estimating equations models were used to compare the differences in prevalence and mean Z-scores for these growth and nutritional outcomes, with separate models made with LBW and SGA as distinct primary predictors. We compared the longitudinal risk of stunting, wasting and underweight during infancy among LBW versus non-LBW and SGA versus non-SGA infants, while also evaluating key potential confounding, explanatory and modifying covariates. Overall, 9.0% of infants were born prematurely, 14.0% of infants were LBW and 22.9% were SGA. LBW infants had significantly increased odds of stunting, wasting and underweight persisting to 12 months of age, and SGA infants had significantly increased odds of stunting and underweight. LBW and SGA infants had higher rates of weight-for-length gain in the first month of life. Maternal educational attainment and exclusive breastfeeding decreased the risk of stunting and undernutrition. In this setting, LBW and SGA infants have higher rates of growth stunting and undernutrition during the first year of life and do not exhibit catch-up growth by 12 months of age.

    In our search for early biomarkers for the pregnancy complicationssmall for gestational age (SGA) and preeclampsia (PE) we analysed plasma from 19-21 weeks gestation in women recruited into the SCOPE study, a prospective cohort of nulliparous women, by differential in gel electrophoresis (DIGE). DIGE revealed the differential expression of clusterin levels and its isoforms in top6-depleted plasma of women who delivered an SGA infant but remained normotensive (SGA-NT; N = 8) compared to healthy women with an uncomplicated pregnancy outcome (Controls, N = 8). Immunosorbent enzyme-linked assay (ELISA) showed that compared to plasma clusterin levels from healthy controls [71.1 (SD 12.4) µg/mL, n = 39], clusterin was decreased in SGA-NT [58.3 (SD 11.7), N = 20, P < 0.0001], increased in women with SGA and PE [81.5 (SD 14.8), N = 20, P < 0.01], but similar in PE alone [71.2 (SD 9.4)g/ml, P = 1.0]. Screening for clusterin levels and/or its different isoformsmay be useful in mid-pregnancy to identify women who subsequently develop SGA but remain normotensive or who develop preeclampsia with SGA.

    Reduced IQ, learning difficulties and poor school performance have been reported in small-for-gestational-age (SGA) subjects. However, few studies include a comprehensive neuropsychological assessment. Our aim was to study neuropsychological functioning in young adults born SGA at term. A comprehensive neuropsychological test battery was administered to 58 SGA subjects (birth weight <10th centile) born at term, and 81 term non-SGA controls (birth weight ≥10th centile). The SGA group obtained significantly (p < .01) lower scores on the attention, executive and memory domains compared to non-SGA controls and showed higher risk of obtaining scores below -1.5 SD on the memory domain (odds ratio = 13.3, 95% confidence interval: 1.57, 112.47). At a subtest level, the SGA group obtained lower scores on most neuropsychological tests, with significant differences on 6 of 46 measures: the Trail Making Test 3 (letter sequencing), the Wechsler Memory Scale mental control and the auditory immediate memory scale, the Design Fluency, the Stroop 3 (inhibition) and the Visual Motor Integration (VMI) motor coordination subtest. Young adults born SGA score more poorly on neuropsychological tests compared with non-SGA controls. Differences were modest, with more significant differences in the memory domain.

    Objective To determine whether small for gestational age (SGA) infants <27 weeks gestation is associated with mortality, morbidity, growth and neurodevelopmental impairment at 18–22 months’ corrected age (CA). Study design This was a retrospective cohort study from National Institute of Child Health and Human Development Neonatal Research Network’s Generic Database and Follow-up Studies. Infants born at <27 weeks’ gestation from January 2006 to July 2008 were included. SGA was defined as birth weight <10th percentile for gestational age by the Olsen growth curves. Infants with birth weight ≥10th percentile for gestational age were classified as non-SGA. Maternal and infant characteristics, neonatal outcomes and neurodevelopmental data were compared between the groups. Neurodevelopmental impairment was defined as any of the following: cognitive score <70 on BSID III, moderate or severe cerebral palsy, bilateral hearing loss (+/− amplification) or blindness (vision <20/200). Logistic regression analysis evaluated the association between SGA status and death or neurodevelopmental impairment. Results There were 385 SGA and 2586 non-SGA infants. Compared with the non-SGA group, mothers of SGA infants were more likely to have higher level of education, prenatal care, cesarean delivery, pregnancy-induced hypertension and antenatal corticosteroid exposure. SGA infants were more likely to have postnatal growth failure, a higher mortality and to have received prolonged mechanical ventilation and postnatal steroids. SGA status was associated with higher odds of death or neurodevelopmental impairment [OR 3.91 (95% CI: 2.91–5.25), P<0.001]. Conclusion SGA status among infants <27 weeks’ gestation was associated with an increased risk for postnatal steroid use, mortality, growth failure and neurodevelopmental impairment at 18–22 months’ CA.

    There are many established risk factors for babies who are small for gestational age (SGA) by population birth weight centiles (usually defined as <10th centile). The confirmed maternal risk factors include short stature, low weight, Indian or Asian ethnicity, nulliparity, mother born SGA, cigarette smoking and cocaine use. Maternal medical history of: chronic hypertension, renal disease, anti-phospholipid syndrome and malaria are associated with increased SGA. Risk factors developing in pregnancy include heavy bleeding in early pregnancy, placental abruption, pre-eclampsia and gestational hypertension. A short or very long inter-pregnancy interval, previous SGA infant or previous stillbirth are also risk factors. Paternal factors including changed paternity, short stature and father born SGA also contribute. Factors associated with reduced risk of SGA or increased birth weight include high maternal milk consumption and high intakes of green leafy vegetables and fruit. Future studies need to investigate risk factors for babies SGA by customised centiles as these babies have greater morbidity and mortality than babies defined as SGA by population centiles.

    In order to understand the nutritional status of preterm, small-for-gestational-age (SGA) infants in the early postnatal period, the growth and body composition of preterm, SGA infants was followed prospectively from birth to the postmenstrual age of 37-40 weeks. The infants were stratified into different groups by gestational age, clinical condition and body proportionality. In each subgroup, the growth and changes in body composition of SGA infants were compared with appropriate-for-gestational-age (AGA) infants of a comparable postmenstrual age. At birth, the SGA infants of both the 31-33 and 34-36 week gestational-age groups were smaller than AGA infants in all body measurements, including arm area (AA), arm muscle area (AMA) and arm fat area (AFA). When the preterm SGA infants had grown to the postmenstrual age of 37-40 weeks, the amount of fat they had accumulated was as much as, or more than that in term AGA infants. Yet, they had less muscle mass and their body weight, body length and head circumference were less than those in term AGA infants. This pattern of growth and the changes in body composition had been persistently observed in SGA infants of different gestational-age groups, different clinical status and different body proportionality. Differences between postnatal enteral nutrition and placental nutrition, or different energy utilization, in preterm SGA infants are hypothesized to account for these observations. The growth of less mature (31-33 weeks gestation) SGA infants and those preterm SGA infants with an eventful clinical course was suboptimal as compared with other SGA infants in the same subgroup. In this study, the weight to length ratio (WLR) was used to define the status of nutrition in preterm SGA infants: WLR < or = 2 S.D. or > 2 S.D. off the reference mean. Infants in both groups showed some catch-up growth in body weight. Yet, at near-term their body weight were still more than 2 S.D. below the mean of term AGA. In each gestational-age

    Background Inadequate maternal nutrition is regarded as one of the most important indicators of fetal growth. The aim of this study was to analyze the associated risk of having a small for gestational age (SGA) infant according to the mother's dairy intake during the first half of pregnancy. Methods A prospective cohort study was performed using 1175 healthy pregnant women selected from the catchment area of Virgen de las Nieves University Hospital, Granada (Spain). SGA was defined as neonates weighing less than the 10th percentile, adjusted for gestational age. Factors associated with SGA were analyzed using logistic regression models. Population attributable fractions of SGA according to dairy intake were estimated. Results Dairy intake among women who gave birth to SGA infants was 513.9, versus 590.3 g/day for women with appropriate size for gestational age infants (P = 0.003). An increased intake of dairy products by 100 g/day during the first half of pregnancy decreased the risk of having a SGA infant by 11.0 %, aOR = 0.89 (0.83, 0.96). A dose-response gradient between dairy intake and SGA was observed. Conclusions An inadequate intake of dairy products is associated with a higher risk of SGA. Our results suggest a possible causal relation between dairy intake during pregnancy and the weight of the newborn, although we cannot discard residual confounding. These results should be further supported by properly designed studies. PMID:26971269

    Prenatal growth restraint, if followed by postnatal overweight, confers risk for adult disease including diabetes. The mechanisms whereby neonatal nutrition may modulate such risk are poorly understood. We studied the effects of nutrition (breast-feeding [BRF] vs. formula-feeding [FOF]) on weight partitioning and endocrine state (as judged by high-molecular-weight [HMW] adiponectin and IGF-I) of infants born small for gestational age (SGA). Body composition (by absorptiometry), HMW adiponectin, and IGF-I were assessed at birth and 4 months in BRF infants born appropriate for gestational age (AGA; n = 72) and SGA infants receiving BRF (n = 46) or FOF (n = 56), the latter being randomized to receive a standard (FOF1) or protein-rich formula (FOF2). Compared with AGA-BRF infants, the catchup growth of SGA infants was confined to lean mass, independently of nutrition. Compared with AGA-BRF infants, SGA-BRF infants had normal HMW adiponectin and IGF-I levels at 4 months, whereas SGA-FOF infants had elevated levels of HMW adiponectin (particularly SGA-FOF1) and IGF-I (particularly SGA-FOF2). In conclusion, neonatal nutrition seems to influence endocrinology more readily than body composition of SGA infants. Follow-up will disclose whether the endocrine abnormalities in SGA-FOF infants can serve as early markers of an unfavorable metabolic course and whether they may contribute to design early interventions that prevent subsequent disease, including diabetes.

    Short stature associated with GH deficiency has been estimated to occur in about 1 in 4000 to 1 in 10,000 in various studies. In the last decade new genetic defects have been described in all the levels of the growth hormone-releasing hormone (GH-RH)-GH-IGF (insulin-like growth factor) axis. Genetic defects in the GHRH and in various parts of the Insulin-like growth factor system have been demonstrated. Genetic defects causing isolated GH deficiency (GHD), as well as multiple pituitary hormonal deficiencies have been analysed in detail. Signalling molecules and transcription factors leading to the development of the pituitary gland have been discovered and their function recognized. In animal models and in humans the importance of the transcription factors HESX1, PROP1, POU1F1, LHX3, LHX4, TBX19, SOX2 and SOX3 has been extensively studied. Genetic alterations of those transcription factors dictate the highly variable phenotype: from isolated hypopituitarism to multiple pituitary hormonal deficiencies with or without malformations (e.g. septo-optic dysplasia or holoprosencephaly). Small for gestational age (SGA) children are increasingly recognized to be a heterogeneous group in which new mechanisms of growth retardation and metabolic disturbances have been proposed. Since SGA is considered to be the main reason for the short stature in 10% of short adults this is a large group with a great potential for novel insights into mechanisms of growth and metabolic disturbances. A group of signalling proteins are involved in prenatal (SGA) growth retardation: IRS-1, PDK1, AKT1, and S6K1. In addition, an attractive modern theory supposes that a disturbed mother-placenta-foetus relation results in the activation of the so-called "thrifty phenotype" of which the IGF system is a vital part. The mechanisms assure short-term postnatal survival in conditions of deficient nutritional supply. However, as a consequence, the abundant postnatal nutritional supply and the "thrifty

    Dual photon absorptiometry using /sup 153/Gd in a whole-body scanner was used to measure lean body mass (LBM) in 51 newborn infants. LBM% decreased exponentially with increasing gestational age in both small for gestational age (SGA) and appropriate for gestational age (AGA) infants. In preterm SGA and AGA infants LBM was 104% and 103%, respectively, indicating that no fat was detectable. In term SGA infants LBM was 98%, which corresponded to 48 gm fat on average, and in term AGA infants LBM was 87%, which corresponded to 452 gm fat on average. The LBM%, ponderal index, and skinfold thickness were significantly different between AGA and SGA infants. Infants with clinical signs of intrauterine wastage had significantly higher LBM% than did infants without signs of weight loss. Our results on LBM% by dual photon absorptiometry agree with earlier dissection data; the clinically applicable methods of (1) height combined with weight (i.e., ponderal index), (2) skinfold thickness, and (3) scoring by clinical observations are useful for the estimation of lack of fat as an indicator of intrauterine growth retardation.

    This study was undertaken to compare amino acid concentrations in maternal and newborn infants' serum in normal pregnancy and two groups of obese women who were born themselves with normal and small for gestational age (SGA) birth weight. Maternal cholesterol, lipoproteins concentrations and maternal and infants amino acid concentrations were evaluated at the time of delivery in 28 normal pregnancies, 46 obese pregnant women with normal birth weight (Ob-AGA group) and 44 obese pregnant women born themselves SGA (Ob-SGA group). Mean birth weight of newborn infants in Ob-SGA group was significantly less than in normal and Ob-AGA groups. Cholesterol and lipoproteins were significantly elevated in obese women (more prominent in Ob-SGA group). Most amino acid concentrations and fetal-maternal amino acid gradients were significantly lower in Ob-SGA group. These data suggest significant changes in placental amino acid transport/synthetic function in obese women who were born themselves SGA.

    Objective The objective of this study was to determine the differences in urinary nephrin among controls, gravidas with preeclampsia (PE), and small-for-gestational age (SGA) infants. We also determined whether or not maternal urinary concentrations of nephrin are associated with the subsequent development of PE and SGA infants. Methods We analyzed maternal urinary levels of nephrin in women who were normal controls (n=50), women who were delivered SGA infants (n=40), and gravidas with PE (n=33) in the first, second and third trimesters. Urinary nephrin concentrations were measured with nephrin enzyme-linked immunosorbent assay kits. Results The levels of urinary nephrin were higher in gravida developing preeclampsia or SGA than in controls after adjusting serum creatinine (P<0.05 for both). Maternal urine concentrations of nephrin were higher in pregnancies complicated by SGA and PE in the third trimester (P<0.05), and also higher in pregnancies complicated by SGA in the first trimester (P<0.05). The sensitivity and specificity of nephrin in predicting SGA from normal pregnancies were 67% and 89% in the first trimester, 60% and 79% in the second trimester, and 80% and 84% in the third trimester, respectively. The sensitivity and specificity of nephrin in predicting PE from normal pregnancies were 67% and 83% in the first trimester and 73% and 79% in the third trimester, respectively. Conclusion We suggest that urinary nephrin can be used as an early marker in pregnancies at risk for developing PE and SGA infants. PMID:24327976

    To assess the influence of intrauterine growth retardation and postnatal development on heart rate variability (HRV) and cardiac reflexes, we studied 27 healthy small for gestational age (SGA) and 23 appropriate for gestational age (AGA) infants during a nap study. Resting HRV was assessed by point dispersion of Poincaré plots for overall (SDRR) and instantaneous beat-to-beat variability (SDDeltaRR) and the ratio (SDRR/SDDeltaRR). Heart rate reflex and arousal responses to a 60 degrees head-up tilt were determined. All tests/measures were repeated twice in quiet and active sleep and in prone and supine sleep positions at 1 and 3 mo of age. SGA infants exhibited higher resting sympathetic tone [SDRR/SDDeltaRR: 1.9 (95% confidence interval: 1.7, 2.0) and 1.7 (95% confidence interval: 1.5, 1.8) in SGA and AGA, respectively; P=0.046] and a tendency for a smaller tachycardic reflex response to the tilt [Deltaheart rate: 24 beats/min (95% confidence interval: 20, 28) and 30 (95% confidence interval: 25, 34)] in SGA and AGA, respectively; P=0.06]. HRV indexes were reduced in the prone compared with supine position (P<0.0001), but reflex tilt responses were unchanged with position. SGA/AGA differences were independent of sleep position. Gestational age weight status did not influence the likelihood of arousal, but prone sleeping per se reduced the odds 2.5-fold. The findings suggest reduced autonomic activity and cardiac reflexes in SGA infants. The finding that the sympathetic component of the control of HRV was higher in SGA infants could link with findings in adulthood of an association between being born SGA and a higher risk of cardiovascular disease.

    Purpose In a prospective prenatal cohort study, we examined associations of second trimester and cord plasma 25-hydroxyvitamin D (25[OH]D) with small-for-gestational age (SGA), and the extent to which vitamin D might explain black/white differences in SGA. Methods We studied 1067 white and 236 black mother-infant pairs recruited from 8 obstetrical offices early in pregnancy in Massachusetts. We analyzed 25(OH)D levels using an immunoassay and performed multivariable logistic models to estimate the odds of SGA by category of 25(OH)D level. Results Mean (standard deviation [SD]) second trimester 25(OH)D level was 60 nmol/L (21) and was lower for black (46 nmol/L [22]) than white (62 nmol/L [20]) women. 59 infants were SGA (4.5%) and more black than white infants were SGA (8.5% vs. 3.7%). The odds of SGA were higher with maternal 25(OH)D levels <25 vs. ≥25 nmol/L (adjusted odds ratio [OR] 3.17; 95% confidence interval [CI]:1.16, 8.63). The increased odds of SGA among black vs. white participants decreased from an OR of 2.04(1.04, 4.04) to 1.68(0.82, 3.46) after adjusting for 25(OH)D. Conclusions Second trimester 25(OH)D levels <25 nmol/L were associated with higher odds of SGA. Our data raise the possibility that Vitamin D status may contribute to racial disparities in SGA.

    This study compared nutrient utilization and postnatal weight gain composition in eight appropriate for gestational age (AGA: birth weight 1293 +/- 107 g; gestational age 28.8 +/- 1.4 weeks) and eight symmetrically growth-retarded (SGA: birth weight 1110 +/- 230 g; gestational age 32.7 +/- 1.9 weeks), very low-birth-weight (VLBW) infants. There was no significant difference in protein, mineral and energy intake between AGA and SGA infants. Nitrogen absorption (84 +/- 3 and 83 +/- 4%) and nitrogen retention (356 +/- 48 and 352 +/- 43 mg/kg/day) were similar in both groups. Fat absorption tended to be lower in AGA (78 +/- 15%) than in SGA (87 +/- 4%) infants. Calcium, phosphorus and magnesium absorptions were similar in AGA and SGA infants. Metabolizable energy utilization was similar in both groups; about 55% was expended and 45% stored in new tissues. Energy expenditure was 58 +/- 4 kcal/kg/day in SGA infants and 61 +/- 9 kcal/kg/day in AGA infants. Weight gain and its composition were similar in both groups. We conclude that nutrient and energy utilization are similar in AGA and symmetrically growth-retarded, VLBW infants.

    Prenatal growth restraint associates with the risk for later diabetes, particularly if such restraint is followed by postnatal formula-feeding (FOF) rather than breast-feeding (BRF). Circulating incretins can influence the neonatal programming of hypothalamic setpoints for appetite and energy expenditure, and are thus candidate mediators of the long-term effects exerted by early nutrition. We have tested this concept by measuring (at birth and at age 4 months) the circulating concentrations of glucagon-like peptide-1 (GLP-1) in BRF infants born appropriate-for-gestational-age (AGA; n=63) and in small-for-gestational-age (SGA) infants receiving either BRF (n=28) or FOF (n=26). At birth, concentrations of GLP-1 were similar in AGA and SGA infants. At 4 months, pre-feeding GLP-1 concentrations were higher than at birth; SGA-BRF infants had GLP-1 concentrations similar to those in AGA-BRF infants but SGA-FOF infants had higher concentrations. In conclusion, nutrition appears to influence the circulating GLP-1 concentrations in SGA infants and may thereby modulate long-term diabetes risk.

    The objective of the study was to assess if small- and large-for gestational age term infants have greater health care utilization during the first year of life. The sample included 28,215 singleton term infants (37-42 weeks) without major birth defects delivered from 1998 through 2007 and continuously enrolled at Kaiser Permanente Northwest for 12 months after delivery. Birth weight for gestational age was categorized into 3 levels: <10th percentile (SGA), 10-90th percentile (AGA), >90th percentile (LGA). Length of delivery hospitalization, re-hospitalizations and sick/emergency room visits were obtained from electronic records. Logistic regression models estimated associations between birth weight category and re-hospitalization. Generalized linear models estimated adjusted mean number of sick/emergency visits. Among term infants, 6.2 % were SGA and 13.9 % were LGA. Of infants born by cesarean section, SGA infants had 2.7 higher odds [95 % 1.9, 3.8] than AGA infants of staying ≥5 nights during the delivery hospitalization; of those born vaginally, SGA infants had 1.5 higher adjusted odds [95 % 1.1, 2.1] of staying ≥4 nights. LGA compared to AGA infants had higher odds of re-hospitalization within 2 weeks of delivery [OR 1.25, 95 % CI 0.99, 1.58] and of a length of stay ≥4 days during that hospitalization [OR 2.6, 95 % CI 1.3, 5.0]. The adjusted mean number of sick/emergency room visits was slightly higher in SGA (7.8) than AGA (7.5) infants (P < .05). Term infants born SGA or LGA had greater health care utilization than their counterparts, although the increase in utilization beyond the initial delivery hospitalization was small. PMID:22855007

    Although much is now known about the effects of intrauterine growth retardation (IUGR) on children born SGA with regard to anthropometric and biochemical parameters and their treatment, there are still many gaps associated with its impact on neurocognitive functions. In our experience published several years ago, IUGR has a negative effect on neurocognitive development, regardless of whether these children showed evidence of catch-up growth or not or of the socio-economic conditions that might contribute to the situation. We have now accumulated a large number of cases, many of whom have been followed longitudinally, some for up to 7 years, many having been treated with GH from the time when this therapy was first approved by the EMA. Apart from the cases mentioned, other confounding factors such as gestational age, Apgar score, neonatal comorbidity and the possible effects of GH treatment have also been included. In addition and using our own reference standards, we now present our experience, which confirms what we had already noted in the past, that IUGR is in itself a condition that often causes psychomotorintellectual impairment, may be extremely severe and tends to worsen. This negative impact of IUGR on neurocognitive development does not depend on how the child grows,spontaneous growth is better and when growth is not altered by GH therapy. Later studies will be able to confirm whether early treatment with GH throughout the 2nd year of life, or an early specific stimulation programme, or the sum of both, can improve the neurocognitive development of these children. IUGR prevention, acting on causal factors that are partly avoidable such as smoking, working conditions and stress during pregnancy (see the corresponding article in this supplement) proves once again to be the best way to stop this negative impact on the IQ of many children born SGA.

    Hepatocytes were isolated from full-term, SGA and AGA piglets at 6 or 48 hours postpartum and were incubated with 1 mM (1-{sup 14}C)-octanoate (C8), -nonanoate (C9) or-oleate (C18:1). The cells oxidized (natom 1-C/(h 10{sup 6} cells)) C9 to Co{sub 2} (12.5) and acid soluble products (28.9) faster than C8 (10.9, 20.6, respectively), and both were oxidized faster than C18:1 (3.9, 9.9) regardless of the piglet age or weight. Oleate accumulated in lipid products 8-fold faster than C8 and C9. No differences between cells from SGA and AGA piglets were detected. Recovery of 1-C in CO{sub 2} was 48% higher in incubations with cells from 48 hours old than from 6 hour old piglets. This increase was attributable to a 70% higher oxygen consumption by 48 hour old cells. Theoretical oxygen consumption rates were computed from the fatty acid flux data and compared to measured oxygen consumption. hepatocytes from SGA and AGA piglets were equally capable of satisfying more that 57% of their energy needs from fatty acid oxidation. The oxygen consumption attributable to C9 metabolism was 30% higher than observed for C8 and C18:1. All fatty acids apparently spared endogenous fuels to a greater degree in 6 hour than in 48 hour piglets.

    Objective: To examine the relationship of race and maternal characteristics and their association with cord blood vitamin D levels and small-for-gestational-age (SGA) status. Study Design: Cord blood vitamin D levels were measured in 438 infants (276 black and 162 white). Multivariable logistic regression models were used to evaluate associations between maternal characteristics, vitamin D status and SGA. Results: Black race, Medicaid status, mean body mass index at delivery and lack of prenatal vitamin use were associated with vitamin D deficiency. Black infants had 3.6 greater adjusted odds (95% confidence interval (CI): 2.4, 5.6) of vitamin D deficiency when compared with white infants. Black infants with vitamin D deficiency had 2.4 greater adjusted odds (95% CI: 1.0, 5.8) of SGA. Vitamin D deficiency was not significantly associated with SGA in white infants. Conclusion: Identification of risk factors (black race, Medicaid status, obesity and lack of prenatal vitamin use) can lead to opportunities for targeted prenatal vitamin supplementation to reduce the risk of neonatal vitamin D deficiency and SGA status.

    Information is needed on breast milk zinc concentration and amount of zinc transferred to the infant in relation to the time since birth for both appropriate-for-gestational-age (AGA) and small-for-gestational-age (SGA) infants. Breast milk zinc concentration and total milk volume were measured among mothers of AGA and SGA infants, using deuterium oxide "dose-to-mother" tracer technique and plasma zinc concentrations of mothers and infants. Forty-six mother-infant pairs (20 AGA and 26 SGA infants) were recruited from a low-income community in Bangladesh. Each mother-infant pair was studied 3 times: at 4, 12, and 24 wk postpartum. During each round, 2-wk studies of breast milk transfer were performed, using deuterium oxide dose-to-mother tracer technique. Breast milk samples were collected on days 1 and 5 of each round to determine milk zinc concentration. Mean ± SD birth weight and length were 3.02 ± 0.2 kg and 0.482 ± 0.012 m, respectively, for AGA and 2.34 ± 0.20 kg and 0.462 ± 0.011 m, respectively, for SGA infants, and both variables were different between groups (birth weight, P < 0.001; length, P < 0.001). Breast milk intake increased gradually with time postpartum in both groups. Breast milk zinc concentration decreased with increasing infant age (P < 0.001) but did not differ for mothers of AGA and SGA infants. Breast milk zinc transfer decreased significantly with age in both groups (P < 0.001) but did not differ by birth-weight category. Breast milk zinc concentration among Bangladeshi mothers and patterns of change at 24 wk were similar to those of wealthier countries, and there was no relation between infant birth-weight category and milk zinc concentration or transfer. This trial was registered at www.clinicaltrials.gov as NCT01728766.

    Background: Epidemiologic evidences suggest a strong association between low birth weight and some diseases in adult life ( hypertension, diabetes, cardiovascular diseases).Aim of this study was to evaluate the obesity/overweight prevalence in a population of children born small for gestation age, SGA children 400, 208 males and 192 females compared to a population of children born appropriate for gestational age 6818 AGA children, 3502 males and 3316 females, during childhood. Our intention was also to build the natural history of weight gain during prepubertal age in children born SGA and AGA. Design and Methods: Observational prospective longitudinal study. We followed our patients from January2001 up to December 2010; weight, height and body mass index (BMI) were evaluated in all the SGA and AGA children. BMI z-score range for defining overweight and obesity was, respectively, 1.13 to 1.7 and >1.7 according to CDC growth charts. Results: In transversal evaluation, we prove that 10-year-old SGA females are twice obese and more overweight compared to equal age AGA females. In longitudinal evaluation, we highlight different observations: SGA children obese at 2 years are still obese at 10 years; the number of obese SGA children increases gradually until the age of 10; AGA children, appear to be less obese than SGA children at 10 years. Conclusion: SGA males and females are more obese at 5 and 10 years compared to the AGA population. Primary care pediatricians, through early detection of the children at risk, can carry out an effective obesity prevention project in SGA children. PMID:27583297

    The association between maternal cadmium (Cd) exposure during pregnancy and the increased risk of fetal growth restriction (FGR) remains controversial. The present study evaluated the association between maternal serum Cd level and risk of small for gestational age (SGA) infants in a Chinese population. The present study analyzed a subsample of the C-ABCS cohort that recruited 3254 eligible mother-and-singleton-offspring pairs. Maternal serum Cd level during pregnancy was measured by graphite furnace atomic absorption spectrometry. The rate and odds ratio (OR) for SGA infant were calculated. The rate for SGA infant was 10.6% among subjects with H-Cd (≥1.06 μg/L), significantly higher than 7.5% among subjects with L-Cd (<1.06 μg/L). OR was 1.45 (95% CI: 1.11, 1.90; P = 0.007) among subjects with H-Cd. Adjusted OR for SGA infants was 1.43 (95% CI: 1.09, 1.88; P = 0.007) among subjects with H-Cd. Taken together, we observe the fact that maternal Cd exposure at middle gestational stage, elevates the risk of SGA in contrast to early gestational stage. The present results might be interesting and worth more discussing, and guarantee to further studies. PMID:26934860

    Aim: To evaluate the effect of antenatal corticosteroids (ANS) on short- and long-term outcomes in small-for-gestational age (SGA) infants. Methods: A retrospective database analysis was performed. A total of 1,931 single infants (birth weight <1,500 g) born at a gestational age between 22 weeks and 33 weeks 6 days who were determined to be SGA registered in the Neonatal Research Network Database in Japan between 2003 and 2007 were evaluated for short-term outcome and long-term outcome. Results: ANS was administered to a total of 719 infants (37%) in the short-term outcome evaluation group and 344 infants (36%) in the long-term outcome evaluation group. There were no significant differences between the ANS group and the no-ANS group for primary short-term outcome (adjusted odds ratio (OR) 0.73; 95% confidence interval (CI) 0.45-1.20; P-value 0.22) or primary long-term outcome (adjusted OR 0.69; 95% CI 0.40-1.17; P-value 0.17). Conclusions: Our results show that ANS does not affect short- or long-term outcome in SGA infants when the birth weight is less than 1500 g. This study strongly suggests that administration of ANS resulted in few benefits for preterm FGR fetuses. PMID:25897289

    AIMS—To investigate the effects of small for gestational age (SGA) in very low birthweight (VLBW) infants on growth and development until the fifth year of life.
METHODS—VLBW (< 1500 g) infants, selected from a prospective study, were classified as SGA (n = 115) on the basis of birth weight below the 10th percentile for gestational age and were compared with two groups of appropriate for gestational age (AGA) infants matched according to birth weight (AGA-BW; n = 115) or gestation at birth (AGA-GA; n = 115). Prenatal, perinatal, and postnatal risk factors were recorded, and duration and intensity of treatment were computed from daily assessments. Body weight, length, and head circumference were measured at birth, five and 20 months (corrected for prematurity), and at 56 months. General development was assessed at five and 20 months with the Griffiths scale of babies abilities, and cognitive development at 56 months with the Columbia mental maturity scales, a vocabulary (AWST) and language comprehension test (LSVTA).
RESULTS—Significant group differences were found in complications (pregnancy, birth, and neonatal), parity, and multiple birth rate. The AGA-GA group showed most satisfactory growth up to 56 months, with both the AGA-BW and SGA groups lagging behind. The AGA-GA group also scored significantly more highly on all developmental and cognitive tests than the other groups. Developmental test results were similar for the SGA and AGA-BW groups at five and 20 months, but AGA-BW infants (lowest gestation) had lower scores on performance intelligence quotient and language comprehension at 56 months than the SGA group. When prenatal and neonatal complications, parity, and multiple birth were accounted for, group differences in growth remained, but differences in cognitive outcome disappeared after five months.
CONCLUSIONS—Being underweight and with a short gestation (SGA and VLBW) leads to poor weight gain and head growth in infancy but does not

    2000-01-01

    BACKGROUND—Preterm birth is often associated with impaired growth. Small for gestational age status confers additional risk.
AIM—To determine the body water content of appropriately grown (AGA) and small for gestational age (SGA) preterm infants in order to provide a baseline for longitudinal studies of growth after preterm birth.
METHODS—All infants born at the Hammersmith and Queen Charlotte's Hospitals between 25 and 30 weeks gestational age were eligible for entry into the study. Informed parental consent was obtained as soon after delivery as possible, after which the extracellular fluid content was determined by bromide dilution and total body water by H218O dilution.
RESULTS—Forty two preterm infants were studied. SGA infants had a significantly higher body water content than AGA infants (906 (833-954) and 844 (637-958) ml/kg respectively; median (range); p = 0.019). There were no differences in extracellular and intracellular fluid volumes, nor in the ratio of extracellular to intracellular fluid. Estimates of relative adiposity suggest a body fat content of about 7% in AGA infants, assuming negligible fat content in SGA infants and lean body tissue hydration to be equivalent in the two groups.
CONCLUSIONS—Novel values for the body water composition of the SGA preterm infant at 25-30 weeks gestation are presented. The data do not support the view that SGA infants have extracellular dehydration, nor is their regulation of body water impaired.

    Objectives Construct an ethnic-specific chart and compare the prediction of adverse outcomes using this chart with the clinically recommended UK-WHO and customised birth weight charts using cut-offs for small-for-gestational age (SGA: birth weight <10th centile) and large-for-gestational age (LGA: birth weight >90th centile). Design Prospective cohort study. Setting Born in Bradford (BiB) study, UK. Participants 3980 White British and 4448 Pakistani infants with complete data for gestational age, birth weight, ethnicity, maternal height, weight and parity. Main outcome measures Prevalence of SGA and LGA, using the three charts and indicators of diagnostic utility (sensitivity, specificity and area under the receiver operating characteristic (AUROC)) of these chart-specific cut-offs to predict delivery and neonatal outcomes and a composite outcome. Results In White British and Pakistani infants, the prevalence of SGA and LGA differed depending on the chart used. Increased risk of SGA was observed when using the UK-WHO and customised charts as opposed to the ethnic-specific chart, while the opposite was apparent when classifying LGA infants. However, the predictive utility of all three charts to identify adverse clinical outcomes was poor, with only the prediction of shoulder dystocia achieving an AUROC>0.62 on all three charts. Conclusions Despite being recommended in national clinical guidelines, the UK-WHO and customised birth weight charts perform poorly at identifying infants at risk of adverse neonatal outcomes. Being small or large may increase the risk of an adverse outcome; however, size alone is not sensitive or specific enough with current detection to be useful. However, a significant amount of missing data for some of the outcomes may have limited the power needed to determine true associations. PMID:25783424

    Summary Background Babies with low birthweight (<2500 g) are at increased risk of early mortality. However, low birthweight includes babies born preterm and with fetal growth restriction, and not all these infants have a birthweight less than 2500 g. We estimated the neonatal and infant mortality associated with these two characteristics in low-income and middle-income countries. Methods For this pooled analysis, we searched all available studies and identified 20 cohorts (providing data for 2 015 019 livebirths) from Asia, Africa, and Latin America that recorded data for birthweight, gestational age, and vital statistics through 28 days of life. Study dates ranged from 1982 through to 2010. We calculated relative risks (RR) and risk differences (RD) for mortality associated with preterm birth (<32 weeks, 32 weeks to <34 weeks, 34 weeks to <37 weeks), small-for-gestational-age (SGA; babies with birthweight in the lowest third percentile and between the third and tenth percentile of a US reference population), and preterm and SGA combinations. Findings Pooled overall RRs for preterm were 6·82 (95% CI 3·56–13·07) for neonatal mortality and 2·50 (1·48–4·22) for post-neonatal mortality. Pooled RRs for babies who were SGA (with birthweight in the lowest tenth percentile of the reference population) were 1·83 (95% CI 1·34–2·50) for neonatal mortality and 1·90 (1·32–2·73) for post-neonatal mortality. The neonatal mortality risk of babies who were both preterm and SGA was higher than that of babies with either characteristic alone (15·42; 9·11–26·12). Interpretation Many babies in low-income and middle-income countries are SGA. Preterm birth affects a smaller number of neonates than does SGA, but is associated with a higher mortality risk. The mortality risks associated with both characteristics extend beyond the neonatal period. Differentiation of the burden and risk of babies born preterm and SGA rather than with low birthweight could guide

    Background The effects of moderate alcohol consumption during pregnancy on adverse pregnancy outcomes have been inconsistent. Objective To review systematically and perform meta-analyses on the effect of maternal alcohol exposure on the risk of low birth weight, preterm birth and small-size-for-gestational age (SGA). Search Strategy Using Medical Subject Headings, a literature search of MEDLINE, EMBASE, CINAHL, CABS, WHOlist, SIGLE, ETOH, and Web of Science between 1 January 1980 and 1 August 2009 was performed followed by manual searches. Selection Criteria Case control or cohort studies were assessed for quality (STROBE), 36 available studies were included. Data collection and Analysis Two reviewers independently extracted the information on low birth weight, preterm birth and SGA using a standardized protocol. Meta-analyses on dose-response relationship were performed using linear as well as first-order and second-order fractional polynomial regressions to estimate best fitting curves to the data. Main Results Compared to abstainers, the overall dose-response relationships for low birth weight and SGA had no effect up to 10 g/day (an average of about 1 drink/day) and preterm birth had no effect up to 18 g/day (an average of 1.5 drinks/day) of pure alcohol consumption; thereafter, the relationship had monotonically increasing risk for increasing maternal alcohol consumption. Moderate consumption during pre-pregnancy was associated with reduced risks for both outcomes. Conclusions Dose-response relationship indicates that heavy alcohol consumption during pregnancy increases the risks of all three outcomes while light to moderate alcohol consumption shows no effect. Preventive measures during antenatal consults should be initiated. PMID:21729235

  17. The associations of parity and maternal age with small-for-gestational-age, preterm, and neonatal and infant mortality: a meta-analysis

    PubMed Central

    2013-01-01

    Background Previous studies have reported on adverse neonatal outcomes associated with parity and maternal age. Many of these studies have relied on cross-sectional data, from which drawing causal inference is complex. We explore the associations between parity/maternal age and adverse neonatal outcomes using data from cohort studies conducted in low- and middle-income countries (LMIC). Methods Data from 14 cohort studies were included. Parity (nulliparous, parity 1-2, parity ≥3) and maternal age (<18 years, 18-<35 years, ≥35 years) categories were matched with each other to create exposure categories, with those who are parity 1-2 and age 18-<35 years as the reference. Outcomes included small-for-gestational-age (SGA), preterm, neonatal and infant mortality. Adjusted odds ratios (aOR) were calculated per study and meta-analyzed. Results Nulliparous, age <18 year women, compared with women who were parity 1-2 and age 18-<35 years had the highest odds of SGA (pooled adjusted OR: 1.80), preterm (pooled aOR: 1.52), neonatal mortality (pooled aOR: 2.07), and infant mortality (pooled aOR: 1.49). Increased odds were also noted for SGA and neonatal mortality for nulliparous/age 18-<35 years, preterm, neonatal, and infant mortality for parity ≥3/age 18-<35 years, and preterm and neonatal mortality for parity ≥3/≥35 years. Conclusions Nulliparous women <18 years of age have the highest odds of adverse neonatal outcomes. Family planning has traditionally been the least successful in addressing young age as a risk factor; a renewed focus must be placed on finding effective interventions that delay age at first birth. Higher odds of adverse outcomes are also seen among parity ≥3 / age ≥35 mothers, suggesting that reproductive health interventions need to address the entirety of a woman’s reproductive period.

    1993-04-01

    This paper follows a previous study comparing women who had repeatedly given birth to small-for-gestational-age (SGA) term infants ('repeater' mothers) with multiparous women who had had only one such infant ('non-repeater' mothers). The present investigation involves the individual matching of each woman in the above groups with a control mother whose offspring were all term non-SGA infants. The study was based on all Western Australian Caucasian women giving birth to singletons and the study population comprised 594 repeater cases with 594 matched controls and 935 non-repeater cases with 935 matched controls. Conditional logistic regression analyses indicated that demographic and paternal factors were significant predictors for recurrent SGA term birth whereas obstetric conditions, particularly preeclampsia, were important for the prediction of isolated SGA term birth. Maternal smoking, low maternal birthweight and lack of higher educational qualifications were associated with both types of SGA birth. After multivariable analyses, a strong and significant association remained between having a first infant as a teenager and recurrent SGA term birth. The tendency to repeat SGA term birth appears to be associated with social, economic and behavioural disadvantage and is unlikely to be ameliorated without fundamental changes in society.

  2. Differential effects of intrauterine and postnatal brain growth failure in infants of very low birth weight.

    Hack, M; Breslau, N; Fanaroff, A A

    1989-01-01

    We investigated the contribution of brain growth failure to outcome in infants of very low birth weight (VLBW; less than 1.5 kg) who were appropriate for gestational age (AGA; n = 379) or small for gestational age (SGA; n = 102). Growth was assessed at birth, term, and 8 and 20 months' corrected age and results of a Bayley Mental Developmental Index (MDI) and neurologic examination were evaluated at 20 months of age. Both groups had similar 20-month MDI scores (93 vs 90) and similar rates of neurologic impairment (14% vs 10%). More SGA infants (25%) than AGA infants (14%) had a subnormal head circumference at 8 months' corrected age, indicating failure to catch up in head growth. Subnormal head size at 8 months predicted the 20-month MDI score for both groups. However, multivariate analysis indicated that, whereas subnormal 8-month head size was directly associated with the MDI score in AGA children, in SGA children 8-month head size was not significantly related to the MDI score when neonatal illness, neurologic impairment, socioeconomic status, and race were controlled for. We conclude that in AGA VLBW infants, subnormal head size at 8 months results from major neonatal illness and has adverse later effects. In SGA infants, subnormal head size at 8 months has many causes, including growth retardation in utero, which may not have an adverse effect on outcome; if subnormal head size is superimposed with neonatal illness, a poorer outcome is likely.

    It is not fully known whether maternal prehypertension is associated with increased risk of adverse fetal outcomes, and it is debated whether increases in blood pressure during pregnancy influence adverse fetal outcomes. We performed a population-based cohort study in nonhypertensive women with term (≥37 weeks) singleton births (n=157 446). Using normotensive (diastolic blood pressure [DBP] <80 mm Hg) women as reference, we calculated adjusted odds ratios with 95% confidence intervals between prehypertension (DBP 80-89 mm Hg) at 36 gestational weeks (late pregnancy) and risks of a small-for-gestational-age (SGA) birth or stillbirth. We further estimated whether an increase in DBP from early to late pregnancy affected these risks. We found that 11% of the study population had prehypertension in late pregnancy. Prehypertension was associated with increased risks of both SGA birth and stillbirth; adjusted odds ratios (95% confidence intervals) were 1.69 (1.51-1.90) and 1.70 (1.16-2.49), respectively. Risks of SGA birth in term pregnancy increased by 2.0% (95% confidence intervals 1.5-2.8) per each mm Hg rise in DBP from early to late pregnancy, whereas risk of stillbirth was not affected by rise in DBP during pregnancy. We conclude that prehypertension in late pregnancy is associated with increased risks of SGA birth and stillbirth. Risk of SGA birth was also affected by rise in DBT during pregnancy. Our findings provide new insight to the relationship between maternal blood pressure and fetal well-being and suggest that impaired maternal perfusion of the placenta contribute to SGA birth and stillbirth.

  5. Predictors of Size for Gestational Age in St. Louis City and County

    PubMed Central

    2014-01-01

    Objective. To identify social, behavioral, and physiological risk factors associated with small for gestational age (SGA) by gestational age category in St. Louis City and County. Methods. A retrospective cohort study was conducted using birth certificate and fetal death records from 2000 to 2009 (n = 142,017). Adjusted associations of risk factors with SGA were explored using bivariate logistic regression. Four separate multivariable logistic regression analyses, stratified by gestational age, were conducted to estimate adjusted odds ratios. Results. Preeclampsia and inadequate weight gain contributed significantly to increased odds for SGA across all gestational age categories. The point estimates ranged from a 3.41 increased odds among women with preeclampsia and 1.76 for women with inadequate weight gain at 24–28 weeks' gestational age to 2.19 and 2.11 for full-term infants, respectively. Among full-term infants, smoking (aOR = 2.08), chronic hypertension (aOR = 1.46), and inadequate prenatal care (aOR = 1.25) had the next most robust and significant impact on SGA. Conclusion. Preeclampsia and inadequate weight gain are significant risk factors for SGA, regardless of gestational age. Education on the importance of nutrition and adequate weight gain during pregnancy is vital. In this community, disparities in SGA and smoking rates are important considerations for interventions designed to improve birth outcomes. PMID:25105127

    Clinical correlates of catch-up growth were documented in 182 very-low-birth-weight (VLBW) infants (less than 1.5 kg) followed up prospectively until a corrected age of 33 months. At birth, 147 infants had weights appropriate for gestational age (AGA), and 35 were small for gestational age (SGA). The infants in each group were categorized as small if body weight was 2 SDs below the mean for age or appropriate if body weight was within 2 SDs of the mean at birth and at corrected ages of 40 weeks and 8, 21, and 33 months. Of the 147 AGA infants, 67 (46%) weighed less than 2 SDs of the mean for age at a corrected age of 40 weeks, 40 (27%) at 8 months, 28 (19%) at 21 months, and 25 (17%) at 33 months. Of the 35 SGA infants, 32 (91%) had subnormal weight at 40 weeks, 17 (49%) at 8 months and 21 months, and 16 (46%) at 33 months. Significant correlates of poor catch-up growth in the AGA group were birth weight, gestational age, severity of neonatal complications, poor neonatal head growth, and chronic physical and neurologic sequelae. In the infants in the SGA group, the correlates of poor catch-up growth were birth weight, multiple birth, and social class.

    To examine the relative importance of intrauterine growth failure, extrauterine growth failure before or after term, and the prognostic significance of catch-up growth, 192 very low--birth weight infants (less than 1.5 kg) were followed prospectively to 8 months corrected age. One hundred fifty-four appropriate--for--gestational age (AGA) and 38 small--for--gestational age (SGA) infants were categorized into normal and subnormal (less than -2 SD) weight for age groups at term (40 weeks) and at 8 months corrected age. By term, 71 AGA infants had subnormal weight; 41 of these caught up by 8 months, and an additional 13 AGA infants failed to thrive between term and 8 months. Of the SGA infants, three caught up in weight by term, and an additional 16 caught up by 8 months. Significant correlates of subnormal weight included neonatal risk score, incidence of chronic disease, and extended hospitalization. The AGA and SGA infants who failed to thrive or failed to catch up in weight by 8 months had lower mean Bayley developmental quotients (p less than 0.005), smaller head circumferences (p less than 0.005), and a higher rate of neurosensory impairment (p less than 0.01) than the AGA infants with normal fetal and postnatal growth. Intrauterine and/or postnatal growth failure prior to term was not of sinister prognostic significance if catch up occurred thereafter.

    2013-01-01

    Several studies have shown that small for gestational age (SGA) babies have a different hormonal profile than those born with a birth weight appropriate for gestational age (AGA). Thyroid hormones play an important role in growth and neurocognitive development. Only few studies analyzed the concentrations of thyroid-stimulating hormone (TSH) and thyroxine (T4) during fetal and extrauterine life in SGA and AGA newborns, and the existing data on the possible alterations of these hormones in postnatal life are controversial. It remains to be established whether SGA newborns have different blood concentrations of thyroid hormones as compared with AGA infants and if so, whether these findings play a role in the development of obesity, short stature, hypertension, and diabetes - disorders, already known to be related with SGA birth. It has also not yet been established whether and when substitutive therapy with levothyroxine (LT4) should be initiated in preterm and full-term SGA newborns. Further trials are needed to determine the thyroid hormone profile in both preterm and full-term SGA newborns and also to evaluate the effectiveness and safety of LT4 treatment in these infants. Conflict of interest:None declared. PMID:23149390

    Objectives To characterize postnatal growth failure (PGF), defined as weight < 10th percentile for postmenstrual age (PMA) in preterm (≤27 weeks’ gestation) infants with severe bronchopulmonary dysplasia (sBPD) at specified time points during hospitalization, and to compare these in subgroups of infants who died/underwent tracheostomy and others. Study Design Retrospective review of data from the multicenter Children’s Hospital Neonatal Database (CHND). Results Our cohort (n = 375) had a mean ± standard deviation gestation of 25 ± 1.2 weeks and birth weight of 744 ± 196 g. At birth, 20% of infants were small for gestational age (SGA); age at referral to the CHND neonatal intensive care unit (NICU) was 46 ± 50 days. PGF rates at admission and at 36, 40, 44, and 48 weeks’ PMA were 33, 53, 67, 66, and 79% of infants, respectively. Tube feedings were administered to > 70% and parenteral nutrition to a third of infants between 36 and 44 weeks’ PMA. At discharge, 34% of infants required tube feedings and 50% had PGF. A significantly greater (38 versus 17%) proportion of infants who died/underwent tracheostomy (n = 69) were SGA, compared with those who did not (n = 306; p < 0.01). Conclusions Infants with sBPD commonly had progressive PGF during their NICU hospitalization. Fetal growth restriction may be a marker of adverse outcomes in this population. PMID:23690052

    Physiological ageing is accompanied by decline in immune system function and immune alteration during ageing increases susceptibility to infections. We retrospectively analysed the data for complete blood count (CBC) and lymphocyte subsets from infant to elderly age groups to determine changes during ageing. Data from dual-platform flow cytometry and CBC were analysed to determine the percentage (%) and absolute cell counts (Abs) of peripheral blood lymphocyte subsets (CD3, CD4, CD8, CD19 and CD56+16+ cells) in infants (1 month to 1 year), children (1 year to 6 years), adolescents (12 years to 18 years), adults (21 years to 50) and elderly (70 years to 92 years). Differences in plasma cytokine levels in adults and elderly were also analysed using Randox system. Comparisons among age groups from infants through adults revealed progressive declines in the percentage of total lymphocytes and absolute numbers of T and B cells. The NK cells declined from infancy to adulthood but increased in elderly participants. The percentages of T cells increased with age from infant to adulthood and then declined. Pro-inflammatory cytokines, TNF-α and IL-6, were higher in elderly people compared to adults. The elderly group had significantly higher levels of monocyte chemoattractant protein-1 (MCP-1) and lower levels of epidermal growth factor (EGF) compared to adults. Our findings confirm and extend earlier reports on age-related changes in lymphocyte subpopulations and data generated from this study is useful for clinicians and researchers, patient management in various age groups for the interpretation of disease-related changes, as well as therapy-dependent alterations.

    Infants born small for gestational age (SGA) are at increased risk of perinatal morbidity, persistent short stature, and metabolic alterations in later life. Recent studies have focused on the association between birth weight (BW) and later body composition. Some reports suggest that fetal nutrition, as reflected by BW, may have an inverse programing effect on abdominal adiposity later in life. This inverse association between BW and abdominal adiposity in adults may contribute to insulin resistance. Rapid weight gain during infancy in SGA children seemed to be associated with increased fat mass rather than lean mass. Early catch-up growth after SGA birth rather than SGA itself has been noted as a cardiovascular risk factor in later life. Children who are born SGA also have a predisposition to accumulation of fat mass, particularly intra-abdominal fat. It is not yet clear whether this predisposition is due to low BW itself, rapid postnatal catch-up growth, or a combination of both. In this report, we review the published literature on central fat accumulation and metabolic consequences of being SGA, as well as the currently popular research area of SGA, including growth aspects.

    Aims: To assess the effect of maternal diet during pregnancy on the risk of delivering a baby who is small for gestational age (SGA). Methods: Case-control study of 844 cases (SGA) and 870 controls (appropriate size for gestational age (AGA)). Only term (37+ completed weeks of gestation) infants were included. Retrospective food frequency questionnaires were completed at birth on the diet at the time of conception and in the last month of pregnancy. Results: At the time of conception, mothers of AGA infants ate significantly more servings of carbohydrate rich food and fruit, and were more likely to have taken folate and vitamin supplements than mothers of SGA infants. There was some evidence that mothers of AGA infants also ate more servings of dairy products, meat, and fish (0.05 < p < 0.1). However, after adjustment for maternal ethnicity, smoking, height, weight, hypertension, and occupation, fish intake (p  =  0.04), carbohydrate-rich foods (p  =  0.04), and folate supplementation (p  =  0.02) were associated with a reduced risk of SGA. In the last month of pregnancy, only iron supplementation was associated with a reduced risk of SGA (p  =  0.05) after adjustment for potential confounders. Conclusions: This study suggests that small variations in maternal diets within the normal range during pregnancy in developed countries are associated with differences in birth weight.

    Despite the importance of early detection to signal lifesaving treatment initiation for HIV+ infants, early infant diagnosis (EID) services have received considerably less attention than other aspects of prevention of mother to child transmission care. This study draws on baseline data from an on-going cluster randomized study of an intervention to improve EID services at six government hospitals across Kenya. Two logistic regressions examined potential predictors of "on time" (infant ≤6 weeks of age) vs. "late" (≥7 weeks) and "on time" versus "very late" (≥12 weeks) EID engagement among 756 mother-infant pairs. A quarter of the infants failed to get "on time" testing. Predictors of "on time" testing included being informed about EID by providers when pregnant, perceiving less HIV stigma, and mother's level of education. Predictors of "very late" testing (≥12 weeks of age) included not being informed about EID by providers when pregnant and living farther from services. Findings highlight the importance of ensuring that health care providers actively and repeatedly inform HIV+ mothers of the availability of EID services, reduce stigma by frequently communicating judgment free support, and assisting mothers in early planning for accessing EID services. Extra care should be focused on engaging mothers with less formal education who are at increased risk for seeking "late" EID testing. This study offers clear targets for improving services so that all HIV-exposed infants can be properly engaged in EID services, thus increasing the potential for the best possible outcomes for this vulnerable population.

    In a nationwide prospective survey on very preterm and very-low-birthweight infants in The Netherlands, the incidence of cot death in infants discharged alive was 15%. The postnatal age at death in these infants did not differ significantly from age at death in other cot death infants. Using a case-control design, possible risk factors associated with cot death were identified: lower maternal age at first pregnancy; maternal smoking during pregnancy; hypothermia of the infant immediately after birth; decreased number of white blood cells and thrombocytes in the infant on the first day of life. Intrauterine hypoxia is hypothesized as the entity common to these factors.

  18. Ontogeny of autonomic regulation in late preterm infants born at 34-37 weeks postmenstrual age.

    2006-04-01

    Late preterm infants (34-37 weeks postmenstrual age at birth) are intermediate between less mature preterm infants and infants born at 38 weeks or more in regard to autonomic brain stem maturation. Ventilatory responses to CO(2) in preterm infants born at 33 to 36 week are significantly higher than in infants born at 29 to 32 weeks both at 3 to 4 and 10 to 14 days postnatal age, but do not differ from full-term reference levels. The ventilatory response to hypoxia in preterm infants is biphasic; initial transient hyperventilation is followed by a return to baseline and then a decrease below baseline. In infants born at 32 to 37 weeks, parasympathetic maturation appears significantly less than in full-term infants based on diminished increases in high frequency heart rate variability in quiet sleep, suggesting that late preterm infants are still more susceptible to bradycardia than full-term infants. Both the presence and severity of apnea of prematurity progressively decrease the higher the postmenstrual age. Late preterm infants, however, are still at risk, with prevalence rates as high as 10% compared with about 60% in infants born at <1500 g. The incidence of apparent life-threatening events is more common in preterm infants (8-10%) than full-term infants (1% or less). In the Collaborative Home Infant Monitoring Evaluation studies, the frequency of conventional and extreme events in near term infants is intermediate between preterm infants <34 weeks at birth and full-term infants. The relative risk for at least one extreme event in late preterm infants is increased (5.6 and 7.6, respectively, P < 0.008) compared with full-term infants and remains higher until 43 weeks postmenstrual age. The rate for Sudden Infant Death Syndrome in preterm infants born at 33 to 36 weeks is 1.37/1000 live births compared with 0.69 in infants born full term. Affected late preterm infants die at a older mean postmenstrual age compared with less mature infants (48 and 46 weeks

    Poor nutrient intake during pregnancy can adversely affect both infant and maternal health. The aim was to investigate the efficacy of multiple-micronutrient supplementation during pregnancy in a socially deprived population in the developed world. We conducted a randomised, double-blind, placebo-controlled trial of multiple-micronutrient supplementation including 20 mg Fe and 400 microg folic acid, from the first trimester of pregnancy in 402 mothers, in East London, UK. Nutrient status was measured at recruitment, and at 26 and 34 weeks of gestation. Infants were weighed at birth. At recruitment the prevalence of anaemia was 13 %, vitamin D insufficiency 72 %, thiamin deficiency 12 % and folate deficiency 5 %, with no differences between groups. Only 39 % of women completed the study; rates of non-compliance were similar in both groups. Intention-to-treat analysis showed that participants receiving treatment had higher mean Hb at 26 weeks of gestation (110 (sd 10) v.108 (sd 10) g/l; P = 0.041) and 34 weeks of gestation (113 (sd 12) v.109 (sd 10) g/l; P = 0.003) and packed cell volume concentrations at 26 weeks of gestation (0.330 (sd 0.025) v. 0.323 (sd 0.026) l/l; P = 0.011) and 34 weeks of gestation (0.338 (sd 0.029) v. 0.330 (sd 0.028) l/l; P = 0.014) compared with controls. Analysis of compliant women showed supplemented women had higher median concentrations of serum ferritin, erythrocyte folate and 25-hydroxyvitamin D later in gestation than controls. In the compliant subset (n 149), placebo mothers had more small-for-gestational age (SGA) infants (eight SGA v. thirteen; P = 0.042) than treatment mothers. Baseline micronutrient deficiencies were common; the multiple-micronutrient supplement was well-tolerated and improved nutrient status. Multiple-micronutrient supplements from early pregnancy may be beneficial and larger studies are required to assess impact on birth outcomes and infant development.

  20. Assessment of cardiorespiratory stability using the infant car seat challenge before discharge in preterm infants (<37 weeks' gestational age).

    Preterm infants younger than 37 weeks corrected gestational age are at increased risk for abnormal control of respiration. The infant car seat challenge has been used as a screening tool to ensure cardiorespiratory stability before discharging preterm infants from many hospitals in Canada. While it is clear that infants placed in a car seat are more likely to experience oxygen desaturation and/or bradycardia than when they are supine, neither positioning predicts an adverse neurodevelopmental outcome or mortality post-discharge. A review of the literature yielded insufficient evidence to recommend routine use of the infant car seat challenge as part of discharge planning for preterm infants. This finding has prompted a change in recommendation from a previous Canadian Paediatric Society position statement published in 2000. PMID:27398056

    Summary Background National estimates for the numbers of babies born small for gestational age and the comorbidity with preterm birth are unavailable. We aimed to estimate the prevalence of term and preterm babies born small for gestational age (term-SGA and preterm-SGA), and the relation to low birthweight (<2500 g), in 138 countries of low and middle income in 2010. Methods Small for gestational age was defined as lower than the 10th centile for fetal growth from the 1991 US national reference population. Data from 22 birth cohort studies (14 low-income and middle-income countries) and from the WHO Global Survey on Maternal and Perinatal Health (23 countries) were used to model the prevalence of term-SGA births. Prevalence of preterm-SGA infants was calculated from meta-analyses. Findings In 2010, an estimated 32·4 million infants were born small for gestational age in low-income and middle-income countries (27% of livebirths), of whom 10·6 million infants were born at term and low birthweight. The prevalence of term-SGA babies ranged from 5·3% of livebirths in east Asia to 41·5% in south Asia, and the prevalence of preterm-SGA infants ranged from 1·2% in north Africa to 3·0% in southeast Asia. Of 18 million low-birthweight babies, 59% were term-SGA and 41% were preterm. Two-thirds of small-for-gestational-age infants were born in Asia (17·4 million in south Asia). Preterm-SGA babies totalled 2·8 million births in low-income and middle-income countries. Most small-for-gestational-age infants were born in India, Pakistan, Nigeria, and Bangladesh. Interpretation The burden of small-for-gestational-age births is very high in countries of low and middle income and is concentrated in south Asia. Implementation of effective interventions for babies born too small or too soon is an urgent priority to increase survival and reduce disability, stunting, and non-communicable diseases.

    Fetal growth restriction (FGR) is a leading cause of perinatal morbidity and mortality. FGR pregnancies are often associated with histological evidence of placental vascular thrombosis. The proteoglycans are important components and regulators of vascular homeostasis. Previous studies from our laboratory highlighted mRNA and protein expression differences in placental proteoglycan decorin (DCN), within a clinically well-characterised cohort of third-trimester idiopathic FGR compared with gestation-matched uncomplicated control pregnancies. We also showed that decorin contributes to abnormal angiogenesis and increased thrombin generation in vitro. These observations suggest that DCN gene expression may contribute to the etiology of FGR. Small for gestational age (SGA) is frequently used as a proxy for FGR and is defined as a birth weight below the 10th percentile of a birth weight curve. We therefore made use of a unique resource of first trimester tissues obtained via chorionic villus sampling during the first trimester to investigate the temporal relationship between altered DCN expression and any subsequent development of SGA. We hypothesized that placental DCN expression is decreased early in gestation in SGA pregnancies. Surplus chorionic villus specimens from 15 women subsequently diagnosed with FGR and 50 from women with uncomplicated pregnancies were collected. DCN mRNA and DCN protein were determined using real-time PCR and immunoblotting, respectively. Both DCN mRNA and protein were significantly decreased in placentae from first-trimester SGA-pregnancies compared with controls (p < 0.05). This is the first study to report a temporal relationship between altered placental DCN expression and subsequent development of SGA. PMID:27577711

    Until relatively recently, long-acting injectable (LAI) formulations were only available for first-generation antipsychotics and their utilization decreased as use of oral second-generation antipsychotics (SGA) increased. Although registry-based naturalistic studies show LAIs reduce rehospitalization more than oral medications in clinical practice, this is not seen in recent randomized clinical trials. PROACTIVE (Preventing Relapse Oral Antipsychotics Compared to Injectables Evaluating Efficacy) relapse prevention study incorporated efficacy and effectiveness features. At 8 US academic centers, 305 patients with schizophrenia or schizoaffective disorder were randomly assigned to LAI risperidone (LAI-R) or physician's choice oral SGAs. Patients were evaluated during the 30-month study by masked, centralized assessors using 2-way video, and monitored biweekly by on-site clinicians and assessors who knew treatment assignment. Relapse was evaluated by a masked Relapse Monitoring Board. Differences between LAI-R and oral SGA treatment in time to first relapse and hospitalization were not significant. Psychotic symptoms and Brief Psychiatric Rating Scale total score improved more in the LAI-R group. In contrast, the LAI group had higher Scale for Assessment of Negative Symptoms Alogia scale scores. There were no other between-group differences in symptoms or functional improvement. Despite the advantage for psychotic symptoms, LAI-R did not confer an advantage over oral SGAs for relapse or rehospitalization. Biweekly monitoring, not focusing specifically on patients with demonstrated nonadherence to treatment and greater flexibility in changing medication in the oral treatment arm, may contribute to the inability to detect differences between LAI and oral SGA treatment in clinical trials.

    Objective To evaluate the association of tenofovir disoproxil fumarate (TDF) use during pregnancy with early growth parameters in HIV-exposed, uninfected (HEU) infants. Design US-based prospective cohort study of HEU children to examine potential adverse effects of prenatal TDF exposure. Methods We evaluated the association of maternal TDF use during pregnancy with small for gestational age (SGA); low birth weight (LBW, <2.5kg); weight-for-age z-scores (WAZ), length-forage z-scores (LAZ) and head circumference-for-age (HCAZ) z-scores at newborn visit; and LAZ, HCAZ, and WAZ at age one year. Logistic regression models for LBW and SGA were fit, adjusting for maternal and sociodemographic factors. Adjusted linear regression models were used to evaluate LAZ, WAZ and HCAZ by TDF exposure. Results Of 2029 enrolled children with maternal antiretroviral information, TDF was used by 449 (21%) HIV-infected mothers, increasing from 14% in 2003 to 43% in 2010. There was no difference between those exposed to combination regimens with versus without TDF for SGA, LBW, and newborn LAZ and HCAZ. However, at age one year, infants exposed to combination regimens with TDF had significantly lower adjusted mean LAZ and HCAZ than those without TDF (LAZ: −0.17 vs. −0.03, p=0.04; HCAZ: 0.17 vs. 0.42, p=0.02). Conclusions TDF use during pregnancy was not associated with increased risk for LBW or SGA. The slightly lower mean LAZ and HCAZ observed at age one year in TDF-exposed infants are of uncertain significance but underscore the need for additional studies of growth outcomes after TDF use during pregnancy.

    Objective The hypothesis is tested that electrocortical functional connectivity (quantified by coherence) of extremely low birth weight (ELBW) infants, measured at term post menstrual age, has regional differences from that of full term infants. Methods 128 lead EEG data were collected during sleep from 8 ELBW infants with normal head ultrasound exams and 8 typically developing full term infants. Regional spectral power and coherence were calculated. Results No significant regional differences in EEG power were found between infant groups. However, compared to term infants, ELBW infants had significantly reduced interhemispheric coherence (in frontal polar and parietal regions) and intrahemispheric coherence (between frontal polar and parieto-occipital regions) in the 1–12 Hz band but increased interhemispheric coherence between occipital regions in the 24–50 Hz band. Conclusions ELBW infants at term post menstrual age manifest regional differences in EEG functional connectivity as compared to term infants. Significance Distinctive spatial patterns of electrocortical synchrony are found in ELBW infants. These regional patterns may presage regional alterations in the structure of the cortex.

    1995-09-01

    Respiratory water loss, oxygen consumption and carbon dioxide production were measured in 32 infants on their first day after birth. Gestational age was between 27 and 41 weeks. All infants were studied in incubators with 50% ambient relative humidity and an ambient temperature that allowed the infant to maintain a normal and stable body temperature. During the measurements the infants were usually asleep. Respiratory water loss was found to be highest in the most preterm infants and lower in more mature infants. Respiratory water loss per breath (mg/kg) was almost the same at all gestational ages and the higher respiratory water loss found in the most preterm as compared with the more mature infants is thus and increased with increasing gestational age. Thus, in full-term infants respiratory water loss and transepidermal water loss are of approximately equal magnitude at an ambient humidity of 50%, while respiratory water loss constitutes a smaller proportion than transepidermal water loss in very preterm infants. Respiratory water loss increases with the rate of breathing.

    The effect of mother-infant skin-to-skin contact on infants' developing social expectations for maternal behavior was investigated longitudinally over infants' first 3 months. Infants with and without skin-to-skin contact engaged with their mothers in the Still Face Task at ages 1 week, 1 month, 2 months, and 3 months. Infants with skin-to-skin contact began responding to changes in their mothers' behavior with their affect at 1 month; infants without skin-to-skin contact did so at 2 months. At 3 months, infants with skin-to-skin contact increased their non-distress vocalizations during the still face phase, suggesting social bidding to their mothers. Skin-to-skin contact accelerated infants' social expectations for their mothers' behavior and enhanced infants' awareness of themselves as active agents in social interactions.

    Objective To examine whether maternal low blood glucose (BG), low body mass index (BMI) and small stature have a joint effect on the risk of delivery of a small-for-gestational age (SGA) infant. Design Women from a perinatal cohort were followed up from receiving perinatal healthcare to giving birth. Setting Beichen District, Tianjin, China between June 2011 and October 2012. Participants 1572 women aged 19–39 years with valid values of stature, BMI and BG level at gestational diabetes mellitus screening (gestational weeks 24–28), glucose challenge test <7.8 mmol/L and singleton birth (≥37 weeks’ gestation). Main outcome measures SGA was defined as birth weight <10th centile for gender separated gestational age of Tianjin singletons. Results 164 neonates (10.4%) were identified as SGA. From multiple logistic regression models, the ORs (95% CI) of delivery of SGA were 0.84 (0.72 to 0.98), 0.61 (0.49 to 0.74) and 0.64 (0.54 to 0.76) for every 1 SD increase in maternal BG, BMI and stature, respectively. When dichotomises, maternal BG (<6.0 vs ≥6.0 mmol/L), BMI (<24 vs ≥24 kg/m2) and stature (<160.0 vs ≥160.0 cm), those with BG, BMI and stature all in the lower categories had ∼8 times higher odds of delivering an SGA neonate (OR (95% CI) 8.01 (3.78 to 16.96)) relative to the reference that had BG, BMI and stature all in the high categories. The odds for an SGA delivery among women who had any 2 variables in the lower categories were ∼2–4 times higher. Conclusions Low maternal BG is associated with an increased risk of having an SGA infant. The risk of SGA is significantly increased when the mother is also short and has a low BMI. This may be a useful clinical tool to identify women at higher risk for having an SGA infant at delivery. PMID:27633632

    Objectives: Early nutrition influences metabolic programming and long-term health. We explored the urinary metabolite profiles of 48 premature infants (birth weight < 1500 g) randomized to an enhanced or a standard diet during neonatal hospitalization. Methods: Metabolomics using nuclear magnetic resonance spectroscopy (NMR) was conducted on urine samples obtained during the first week of life and thereafter fortnightly. Results: The intervention group received significantly higher amounts of energy, protein, lipids, vitamin A, arachidonic acid and docosahexaenoic acid as compared to the control group. Enhanced nutrition did not appear to affect the urine profiles to an extent exceeding individual variation. However, in all infants the glucogenic amino acids glycine, threonine, hydroxyproline and tyrosine increased substantially during the early postnatal period, along with metabolites of the tricarboxylic acid cycle (succinate, oxoglutarate, fumarate and citrate). The metabolite changes correlated with postmenstrual age. Moreover, we observed elevated threonine and glycine levels in first-week urine samples of the small for gestational age (SGA; birth weight < 10th percentile for gestational age) as compared to the appropriate for gestational age infants. Conclusion: This first nutri-metabolomics study in premature infants demonstrates that the physiological adaptation during the fetal-postnatal transition as well as maturation influences metabolism during the breastfeeding period. Elevated glycine and threonine levels were found in the first week urine samples of the SGA infants and emerged as potential biomarkers of an altered metabolic phenotype. PMID:24824288

    2010-01-01

    A clear relationship exists between undernutrition, poorer growth and poor development in term and preterm infants. However, preterm infants are at greater risk than term infants. Undernutrition is more common and 'programmed' growth rates are almost six times faster. Thus, even short periods of nutritional deprivation may have significant effects. Recent advances have led to an improvement in early growth but very low birthweight infants remain small for gestational age at hospital discharge. Studies suggest that a 'window of opportunity' exists after hospital discharge, in that better growth between discharge and 2-3 months corrected age is paralleled by better development, and poorer growth is associated with poorer development. However, interventions aimed at improving growth and development have yielded varying results. This may partly be related to differences in study design as well as the composition of the nutrient-enriched formulas. Irrespective, one point is concerning, i.e. infant boys appear to be at a developmental disadvantage when fed a term infant formula after discharge. A single study has also suggested that dietary intervention can improve brain growth in term and preterm infants with perinatal brain injury. However, concern has been expressed about rapid 'catch-up' growth in preterm infants and the development of insulin resistance and visceral adiposity. Data from our group do not support the idea of increased or altered adiposity in preterm infants fed a nutrient-enriched formula after hospital discharge.

    Objective Birth defects are a leading cause of infant mortality in the United States. Previous reports have highlighted black-white differences in overall infant mortality and infant mortality attributable to birth defects (IMBD). We evaluated the impact of gestational age on US racial/ethnic differences in IMBD. Methods We estimated the rate of IMBD (using ICD-10 codes for the underlying cause of death) using the period linked birth/infant death data for US residents for January 2003 to December 2006. We excluded infants with missing gestational age, implausible values based on Alexander’s index of birth weight for gestational age norms, or gestational ages <20 weeks or >44 weeks; we categorized gestational age into three groups: 20–33; 34–36; and 37–44 weeks. Using Poisson regression, we compared neonatal and postneonatal mortality attributable to birth defects for infants of non-Hispanic black and Hispanic mothers with that for infants of non-Hispanic white mothers stratified by gestational age. Results IMBD occurred in 12.2 per 10,000 live births. Among infants delivered at 37–44 weeks, blacks (and Hispanics, to a lesser degree) had significantly higher neonatal and postneonatal mortality attributable to birth defects than whites. However, among infants delivered at 20–33 or 34–36 weeks, neonatal (but not postneonatal) mortality attributable to birth defects was significantly lower among blacks compared with whites. Conclusions Racial/ethnic differences in IMBD were not explained in these data by differences in gestational age. Further investigation should include an assessment of possible racial/ethnic differences in severity and/or access to timely diagnosis and management of birth defects. PMID:22908111

    The Glasgow Coma Scale (GCS) is the most frequently used tool worldwide for assessing the severity of neurologic injury after brain trauma, although applying this scale to infants and younger children can be problematic. The CHOP Infant Coma Scale, or Infant Face Scale (IFS), is a novel scale for children under 2 years of age which differs from other pediatric coma scales in the following ways: (1) it relies on objective behavioral observations; (2) it assesses cortical as well as brainstem function; (3) it parallels the GCS in scoring but is based on infant-appropriate behaviors; and (4) it can be applied to intubated patients. We report the results of a prospective study designed to compare interrater reliability between the IFS and GCS in children less than 2 years of age. Seventy-five hospitalized children less than 2 years of age were assessed simultaneously by a pair of observers, representing a spectrum of health care professionals, who scored the children using both the IFS and GCS. Interrater reliability for each pair of observers for each scale was assessed using the kappa statistic. A second series of 10 infants in the intensive care unit with specific diagnoses of acute traumatic or hypoxic/ischemic brain injury were similarly assessed. In the 75 hospitalized infants with a variety of diagnoses, interrater reliability for the GCS was in the "almost perfect," "slight," and "fair" range for the eye-opening, motor, and verbal subtests, respectively. In contrast, the IFS showed interrater reliability in the "almost perfect," "substantial," and "almost perfect" ranges for the three subtests. When applied to infants in an intensive care unit with acute traumatic brain injury or hypoxia/ischemia, the GCS interrater reliability scores were in the "fair" range, while the IFS scores were in the "almost perfect" range. The IFS demonstrates improved interrater reliability in direct comparison to the GCS, particularly in the "verbal/face" component where most

    The Bayley Scales of Infant Development were administered at 1 year of age to 54 healthy infants of adolescent mothers. Information was obtained regarding maternal cognitive and emotional maturity, child-rearing attitudes, attitudes toward the infant, and psychosocial status at one year. The average Bayley Mental Scale score was 113, and the average Bayley Motor Scale score was 105. There was a negative correlation between the Bayley Mental Scale score and maternal age and education. Bayley Motor Scale scores were predictable from a combination of maternal authoritarian attitudes, abuse potential, and infant's birth weight. Although high authoritarian attitudes in mothers have been associated with poor cognitive development at later ages, they may represent an important strength in adolescent mothers during the first year.

    Objectives To examine the association between maternal relationship status during pregnancy and infant birth outcomes. Methods Observational study of the National Longitudinal Survey of Youth 1979, a nationally representative sample of 12,686 men and women between the ages of 14 and 21. We used data from surveys of women reporting childbirth between 1979 and 2004. Relationship status was defined as relationship with an opposite-sex partner in the child's birth year. Relationship stability was defined as the consistency in relationship status in the 1 year before, of, and after the child's birth. Childbirth outcome included small-for-gestational age (SGA) infant. We applied random effects logistic regression models to assess the association between relationship status and stability and childbirth outcome-adjusting for maternal race, infant sex, history of miscarriage, employment, maternal age, multiparity, cohort-entry year, household poverty status, and tobacco use.

In fully adjusted models, term SGA infants were more commonly born to partnered women (AOR 1.81; 95 % CI 1.20-2.73) and unmarried women (AOR 1.82; CI 1.34-2.47; LRT p value 0.0001), compared to married women. SGA infants were also more commonly born in unstable relationships (AOR 1.72; 95 % CI 1.14-2.63; LRT p value 0.01) compared to stable relationships. Conclusions for Practice Maternal relationship status and stability during pregnancy is independently associated with risk of SGA infant birth. PMID:27007984

    A survey of the habitats occupied by 12 infants of one month of age revealed that approximately 10% of their day was spent in conditions of potential exposure to the major (P1) allergen of the house dust mite, Dermatophagoides pteronyssinus. A respiratory pump which reproduced the minute ventilation of an infant was placed in representative infant habitats. The P1 allergen trapped by the filter in this pump was measured as an estimate of infants' allergen intake. Detectable P1 intake was only present when there was active air disturbance (bed making and vacuuming). The average P1 intake was approximately 3 ng P1/24 hours. Comparison of this P1 intake with that which sensitizes in other situations suggests that it is usually inadequate to sensitize infants.

    Gestational weight gain is known to influence fetal growth. However, it is unclear whether the associations between gestational weight gain and fetal growth vary by trimester. In a diverse cohort of 8,977 women who delivered a singleton between 2011 and 2013, we evaluated the associations between trimester-specific gestational weight gain and infant size for gestational age. Gestational weight gain was categorized per the 2009 Institute of Medicine (IOM) recommendations; meeting the recommendations was the referent. Large for gestational age and small for gestational age were defined as birthweight > 90th percentile or <10th percentile, respectively, based on a national reference standard birthweight distribution. Logistic regression models estimated the odds of having a large or small for gestational age versus an appropriate for gestational age infant. Only gestational weight gain exceeding the IOM recommendations in the 2nd and 3rd trimesters independently increased the odds of delivering a large for gestational age infant (Odds Ratio (95% Confidence Interval): 1st: 1.17 [0.94, 1.44], 2nd: 1.47 [1.13, 1.92], 3rd: 1.70 [1.30, 2.22]). Gestational weight gain below the IOM recommendations increased the likelihood of having a small for gestational age infant in the 2nd trimester only (1.76 [1.23, 2.52]). There was effect modification, and gestational weight gain below the IOM recommendations increased the likelihood of having a small for gestational age infant in the 2nd trimester and only among women with a pre-pregnancy body mass index from 18.5–24.9 kg/m2 (2.06 [1.35, 3.15]). These findings indicate that gestational weight gain during the 2nd and 3rd trimesters is more strongly associated with infant growth. Interventions to achieve appropriate gestational weight gain may optimize infant size at birth. PMID:27442137

    In the present study, we evaluated the correlation between iron deficiency (ID) and zinc deficiency (ZD) and explored the demographic, anthropometric, and feeding-related factors associated with hypozincemia and hair zinc content in weaning infants. Infants aged 6-24 months were recruited, their feeding history was recorded, and their heights and weights were measured. Hemoglobin content, serum iron/total iron-binding capacity, and ferritin and zinc concentrations of serum and hair (using inductively coupled plasma-mass spectroscopy) were assessed. Among 101 infants, 64 (63.4 %) infants exhibited ID. The median serum zinc concentration in iron-deficient infants was lower than that in non-iron-deficient infants, respectively, 73.5 μg/dL (interquartile range [IQR], 65.0-83.8) vs. 87.0 μg/dL (IQR, 77.5-97.0; p = 0.001). The frequency of hypozincemia was also significantly higher in the iron-deficient group than in the non-iron-deficient group (21 out of 64 [32.8 %] vs. 4 out of 37 [10.8 %], respectively; p = 0.014). In multiple regression analysis, the risk of hypozincemia was significantly increased in infants with ID (p = 0.026), mildly underweight infants (weight-for-age Z score < -1; p = 0.034), and infants with mild wasting (weight-for-height Z score < -1; p = 0.028). Hair zinc concentrations (n = 81) were not significantly associated with ID status (p > 0.1); however, there was an inverse relationship between hair zinc concentrations and age of infants (r = -0.250; p = 0.024). In weaning infants, ID is a risk factor for hypozincemia. Hair zinc concentrations appeared to decrease as the age of infants increased during late infancy. Further large-scale studies are needed to validate the relationship between hypozincemia and mild degrees of weight gain impairment in this age group.

    (1) Background: Late preterm infants account for the majority of preterm births and are at risk of altered body composition. Because body composition modulates later health outcomes and human milk is recommended as the normal method for infant feeding, we sought to investigate whether human milk feeding in early life can modulate body composition development in late preterm infants; (2) Methods: Neonatal, anthropometric and feeding data of 284 late preterm infants were collected. Body composition was evaluated at term-corrected age by air displacement plethysmography. The effect of human milk feeding on fat-free mass and fat mass content was evaluated using multiple linear regression analysis; (3) Results: Human milk was fed to 68% of the infants. According to multiple regression analysis, being fed any human milk at discharge and at  term-corrected and being fed exclusively human milk at term-corrected age were positively associated with fat-free mass content(β = −47.9, 95% confidence interval (CI) = −95.7; −0.18; p = 0.049; β = −89.6, 95% CI = −131.5; −47.7; p < 0.0001; β = −104.1, 95% CI = −151.4; −56.7, p < 0.0001); (4) Conclusion: Human milk feeding appears to be associated with fat-free mass deposition in late preterm infants. Healthcare professionals should direct efforts toward promoting and supporting breastfeeding in these vulnerable infants. PMID:27782098

    Two complementary studies focused on stability of infant temperament across the 1st year and considered infant age, gender, birth order, term status, and socioeconomic status (SES) as moderators. Study 1 consisted of 73 mothers of firstborn term girls and boys queried at 2, 5, and 13 months of age. Study 2 consisted of 335 mothers of infants of different gender, birth order, term status, and SES queried at 6 and 12 months. Consistent positive and negative affectivity factors emerged at all time points across both studies. Infant temperament proved stable and robust across gender, birth order, term status, and SES. Stability coefficients for temperament factors and scales were medium to large for shorter (< 9 months) interassessment intervals and small to medium for longer (> 10 months) intervals.

Twenty-eight infants were considered eutrophic and 29 presented chronic and severe malnutrition. 2. Hair segments less than 3-cm long were cut close to the scalp in the occipital area and washed in deionized water and acetone. Zinc levels were measured by neutron-activation. 3. Hair zinc concentration decreased with age in both eutrophic and malnourished infants from 160 micrograms/g at 7 months to 90 micrograms/g at 24 months. 4. No statistically significant difference in hair zinc concentration was detected between eutrophic and malnourished infants (148 +/- 60 vs 128 +/- 57 micrograms/g hair, mean +/- SD) or between sexes.

    Whether intraventricular hemorrhage increases the risk of adverse developmental outcome among premature infants is controversial. Using brain ultrasound, we identified intraventricular hemorrhage and white matter abnormalities among 1064 infants born before 28 weeks' gestation. We identified adverse developmental outcomes at 24 months of age using a standardized neurologic examination and the Bayley Scales of Infant Development Mental and Motor Scales. In logistic regression models that adjusted for gestational age, sex, and public insurance, isolated intraventricular hemorrhage was associated with visual fixation difficulty but no other adverse outcome. Infants who had a white matter lesion unaccompanied by intraventricular hemorrhage were at increased risk of cerebral palsy, low Mental and Motor Scores, and visual and hearing impairments. Except when accompanied or followed by a white matter lesion, intraventricular hemorrhage is associated with no more than a modest increase (and possibly no increase) in the risk of adverse developmental outcome during infancy.

    AIM—To study the relation between fetal growth and markers of collagen metabolism and insulin-like growth factor binding protein-1 (IGFBP-1) in term infants.
METHODS—Cord vein plasma was obtained from 67 term infants of gestational age 37.1-41.7 weeks (39 appropriate for gestational age (AGA), 11 large for gestational age (LGA; relative birth weight ⩾ 2.0 SD), and 17 small for gestational age (SGA; relative birth weight ⩽ −2.0 SD)) for analysis of markers of metabolism of collagen type I (PICP and ICTP) and III (PIIINP) and of IGFBP-1.
RESULTS—Negative correlations existed between gestational age and PICP (r = −0.294, p = 0.0158), ICTP (r = −0.338, p = 0.0052), and PIIINP (r = −0.432, p = 0.0003). These correlations were also found in SGA infants (all p < 0.05). IGFBP-1 showed negative correlations with birth weight and relative birth weight (r = −0.644, p = 0.0001, and r = −0.693, p = 0.0001 respectively) but not with gestational age (p>0.05).
CONCLUSIONS—In the term fetus, collagen metabolism is primarily dependent on maturity and not on intrauterine growth status, whereas IGFBP-1 reflects intrauterine growth independently of maturity.

    This study investigated prosodic and structural characteristics of infant-directed speech to hearing-impaired infants as they gain hearing experience with a cochlear implant over a 12-month period of time. Mothers were recorded during a play interaction with their HI infants (N = 27, mean age 18.4 months) at 3, 6, and 12 months post-implantation. Two separate control groups of mothers with age-matched normal-hearing infants (NH-AM) (N = 21, mean age 18.1 months) and hearing experience-matched normal-hearing infants (NH-EM) (N = 24, mean age 3.1 months) were recorded at three testing sessions. Mothers produced less exaggerated pitch characteristics, a larger number of syllables per utterance, and faster speaking rate when interacting with NH-AM as compared to HI infants. Mothers also produced more syllables and demonstrated a trend suggesting faster speaking rate in speech to NH-EM relative to HI infants. Age-related modifications included decreased pitch standard deviation and increased number of syllables in speech to NH-AM infants and increased number of syllables in speech to HI and NH-EM infants across the 12-month period. These results suggest that mothers are sensitive to the hearing status of their infants and modify characteristics of infant-direct speech over time. PMID:24244108

    The aim of this study was to clarify the effects of gestational age and birth weight on outcomes of the infants. Medical records of 36 infants with trisomy 18 admitted to Tokyo Women's Medical University Hospital from 1991 to 2012 were reviewed retrospectively. We compared clinical characteristics between term infants (n = 15) and preterm infants (n = 21). There were one very‐low‐birth‐weight (VLBW) term infant (5%) and 12 VLBW preterm infants (80%). Although there were no significant differences in clinical characteristics and provided management between the two groups, none of the preterm infants achieved survival to discharge. On the other hand, 6 of 21 term infants (29%) achieved survival to discharge (P < 0.05). Similar results were obtained for comparisons between the VLBW infants and non‐VLBW infants. Multiple logistic regression analysis revealed that shorter gestational age had a more negative impact than lower birth weight to survival to discharge in infants with trisomy 18. In both preterm and term groups, the infants who died before 30 days commonly died of respiratory failure or apnea. Whereas, the infants who survived more than 30 days mostly died of heart failure. © 2015 The Authors. American Journal of Medical Genetics Part A Published by Wiley Periodicals, Inc. PMID:26307940

    This study characterized the longitudinal evolution of HPA axis functioning from 7 to 16 months of age and identified individual and environmental factors that shape changes in HPA axis functioning over time. Participants were 167 mother-infant dyads drawn from a larger longitudinal study, recruited based on maternal history of being maltreated during childhood. Salivary cortisol levels were assessed before and after age-appropriate psychosocial stressors when infants were 7 and 16 months old. Maternal observed parenting and maternal reports of infant and environmental characteristics were obtained at 7 months and evaluated as predictors of changes in infant baseline cortisol and reactivity from 7 to 16 months. Results revealed that infants did not show a cortisol response at 7 months, but reactivity to psychosocial stress emerged by 16 months. Individual differences in cortisol baseline and reactivity levels over time were related to infant sex and maternal overcontrolling behaviors, underscoring the malleable and socially informed nature of early HPA axis functioning. Findings can inform prevention and intervention efforts to promote healthy stress regulation during infancy. PMID:25783617

    Objective To test whether earlier age at weaning (age 3-6 months) may promote faster growth during infancy. Study design Weaning at age 3.0-7.0 months was reported by 571 mothers of term singletons in a prospective birth cohort study conducted in Cambridge, UK. Infant weight and length were measured at birth and at age 3 months and 12 months. Anthropometric values were transformed into age- and sex-adjusted z-scores. Three linear regression models were performed, including adjustment for confounders in a stepwise manner. Measurements at age 3 months, before weaning, were used to consider reverse causality. Results Almost three-quarters (72.9%) of infants were weaned before age 6 months. Age at weaning of 3.0-7.0 months was inversely associated with weight and length (but not with body mass index) at 12 months (both P ≤ .01, adjusted for maternal and demographic factors). These associations were attenuated after adjustment for type of milk feeding and weight or length at age 3 months (before weaning). Rapid weight gain between 0 and 3 months predicted subsequent earlier age at weaning (P = .01). Our systematic review identified 2 trials, both reporting null effects of age at weaning on growth, and 15 observational studies, with 10 reporting an inverse association between age at weaning and infant growth and 4 reporting evidence of reverse causality. Conclusion In high-income countries, weaning between 3 and 6 months appears to have a neutral effect on infant growth. Inverse associations are likely related to reverse causality. PMID:26073105

    Objective Understanding healthy brain development in utero is crucial in order to detect abnormal developmental trajectories due to developmental disorders. However, in most studies neuroimaging was done after a significant postnatal period, and in those studies that performed neuroimaging on fetuses, the quality of data has been affected due to complications of scanning during pregnancy. To understand healthy brain development between 37–41 weeks of gestational age, our study assessed the in utero growth of the brain in healthy term born babies with DTI scanning soon after birth. Methods A cohort of 93 infants recruited from maternity hospitals in Singapore underwent diffusion tensor imaging between 5 to 17 days after birth. We did a cross-sectional examination of white matter microstructure of the brain among healthy term infants as a function of gestational age via voxel-based analysis on fractional anisotropy. Results Greater gestational age at birth in term infants was associated with larger fractional anisotropy values in early developing brain regions, when corrected for age at scan. Specifically, it was associated with a cluster located at the corpus callosum (corrected p<0.001), as well as another cluster spanning areas of the anterior corona radiata, anterior limb of internal capsule, and external capsule (corrected p<0.001). Conclusions Our findings show variation in brain maturation associated with gestational age amongst ‘term’ infants, with increased brain maturation when born with a relatively higher gestational age in comparison to those infants born with a relatively younger gestational age. Future studies should explore if these differences in brain maturation between 37 and 41 weeks of gestational age will persist over time due to development outside the womb. PMID:25535959

  17. Genetic factors associated with small for gestational age birth and the use of human growth hormone in treating the disorder.

    PubMed

    2012-05-15

    The term small for gestational age (SGA) refers to infants whose birth weights and/or lengths are at least two standard deviation (SD) units less than the mean for gestational age. This condition affects approximately 3%-10% of newborns. Causes for SGA birth include environmental factors, placental factors such as abnormal uteroplacental blood flow, and inherited genetic mutations. In the past two decades, an enhanced understanding of genetics has identified several potential causes for SGA. These include mutations that affect the growth hormone (GH)/insulin-like growth factor (IGF)-1 axis, including mutations in the IGF-1 gene and acid-labile subunit (ALS) deficiency. In addition, select polymorphisms observed in patients with SGA include those involved in genes associated with obesity, type 2 diabetes, hypertension, ischemic heart disease and deletion of exon 3 growth hormone receptor (d3-GHR) polymorphism. Uniparental disomy (UPD) and imprinting effects may also underlie some of the phenotypes observed in SGA individuals. The variety of genetic mutations associated with SGA births helps explain the diversity of phenotype characteristics, such as impaired motor or mental development, present in individuals with this disorder. Predicting the effectiveness of recombinant human GH (hGH) therapy for each type of mutation remains challenging. Factors affecting response to hGH therapy include the dose and method of hGH administration as well as the age of initiation of hGH therapy. This article reviews the results of these studies and summarizes the success of hGH therapy in treating this difficult and genetically heterogenous disorder.

    The purpose of this study was to examine the association between prenatal exposure to cigarettes and heart rate during an object manipulation task at 9 months of age. Second-by-second heart rate was recorded for 181 infants who were prenatally exposed to cigarettes and 77 nonexposed infants during the manipulation of four standardized toys. A series of longitudinal multilevel models were run to examine the association of prenatal smoking on the intercept and slope of heart rate during four 90-second object manipulation tasks. After controlling for maternal age, prenatal marijuana and alcohol use, duration of focused attention and activity level, results indicated that the heart rates of exposed infants significantly increased during the object manipulation task. These findings suggest casual rather than focused attention and a possible increase in physiological arousal during object manipulation. PMID:25681531

    Delays in the motor domain have been frequently observed in preterm children, especially those born at an extremely low gestational age (ELGA;<28 weeks GA). However, early motor exploration has received relatively little attention despite its relevance for object knowledge and its impact on cognitive and language development. The present study aimed at comparing early object exploration in 20 ELGA and 20 full-term (FT) infants at 6 months of age during a 5-minute mother-infant play interaction. Object engagement (visual vs manual), visual object engagement (no act vs reach), manual object engagement (passive vs active), and active object manipulation (mouthing, transferring, banging, turn/rotating, shaking, fingering) were analyzed. Moreover, the Griffiths Mental Development Scales 0-2 years (1996) were administered to the infants. Relative to FT peers, ELGA infants spent more time in visual engagement, and less time in manual engagement, active manipulation, mouthing, and turning/rotating. Moreover, they had lower scores on general psychomotor development, eye & hand coordination, and performance abilities. Close relationships emerged between manual object engagement and psychomotor development. Clinical implications of these results in terms of early evaluation of action schemes in ELGA infants and the provision of intervention programs for supporting these abilities are discussed.

    Little research exists that addresses the differences in feeding skills between preterm (PT) infants at term and full-term (FT) infants. The purpose of this study was to quantify and examine the differences in sucking abilities of PT infants when measured at 40 weeks postconceptional age (PCA) and newly born FT infants. The sample consisted of 213 infants who were divided into three groups on the basis of their gestational age at birth (24-29 wk, 30-32 wk, and 38-42 wk). The Kron Nutritive Sucking Apparatus (KNSA) was used to examine the microstructure of sucking and feeding behaviors. There were significant differences among the three groups in several of the sucking variables: number of bursts (p = .005), intersuck interval (p = .0212), sucks per burst (p = .0003), suck width (p < .0001), intersuck width (p < .0001), mean maximum pressure (p < .0001), and intersuck width/interburst width (p = .02). The findings from this study demonstrate the importance of both maturation at birth and experience as factors influencing feeding behaviors. PMID:12177569

    Infant feeding poses many challenges, such as the rapid growth of the child and the immature nature of his or her body¿s systems. Foods that are poorly suited to such immaturity can lead to functional problems and even sometimes-serious allergies. Infant nutritional intake is also influenced by environmental, socioeconomic, and cultural factors. Of these factors, the eating habits of Tunisians, with a tendency to overconsume cereal- and sugar-based products, is of particular concern. The authors examined the nutritional intakes of 342 healthy infants aged 6-14 months from the Tunis region. The 180 boys and 162 girls were recruited in 5 primary health centers in Tunis, as well as from several suburbs. These centers were chosen at random from among the region¿s 144 centers. Energy intakes are close to those recommended for infants aged 8-14 months, yet low for those aged 6-8 months. Protein supply is about 2.5 g/kg weight/day. Lipids consumed cover more than 35% of the energy supply for infants aged 6-8 and 12-14 months. Glucidic consumption is slightly higher for babies aged 8-12 months who have an energy supply covered sometimes by more than 60% of glucid. With regard to key vitamin and mineral supplies, there are deficits in vitamins C and D, as well as in calcium. There is a good supply of iron. The observed disequilibria in nutritional intake are not alarming, but parents need to be aware of them in order to reduce the risks of deficiencies in vitamins and minerals. PMID:10392033

    In infants under 6 months of age, paracetamol overdose is usually due to dose confusion by caretakers. Recently, liquid formulations of this drug have been commercialized in larger,60-ml bottles. The syringe to measure the syrup in these new formulations is also bigger (5 cc versus 1.2-2 cc). We present six cases of 2-4-month-old infants mistakenly given an overdose of paracetamol, each from this new 60-ml formulation. These patients are especially susceptible to poisoning because of liver immaturity and require more aggressive management. To prevent this kind of poisoning, correct and clear information must be given to caregivers about drug dosage. PMID:14757024

  9. The Impact of Early Age at First Childbirth on Maternal and Infant Health

    2015-01-01

    The objective of this review was to assess whether early age at first childbirth is associated with increased risk of poor pregnancy outcomes. Early age at childbirth is variously defined in studies of its effect on maternal and infant health. In this systematic review, we limit analysis to studies of at least moderate quality that examine first births among young mothers, where young maternal age is defined as low gynaecological age (≤2 years since menarche) or as a chronological age ≤16 years at conception or delivery. We conduct meta-analyses for specific maternal or infant health outcomes when there are at least three moderate quality studies that define the exposure and outcome in a similar manner and provide odds ratios or risk ratios as their effect estimates. We conclude that the overall evidence of effect for very young maternal age (<15 years or <2 years post-menarche) on infant outcomes is moderate; that is, future studies are likely to refine the estimate of effect or precision but not to change the conclusion. Evidence points to an impact of young maternal age on low birthweight and preterm birth, which may mediate other infant outcomes such as neonatal mortality. The evidence that young maternal age increases risk for maternal anaemia is also fairly strong, although information on other nutritional outcomes and maternal morbidity/mortality is less clear. Many of the differences observed among older teenagers with respect to infant outcomes may be because of socio-economic or behavioural differences, although these may vary by country/ setting. Future, high quality observational studies in low income settings are recommended in order to address the question of generalisability of evidence. In particular, studies in low income countries need to consider low gynaecological age, rather than simply chronological age, as an exposure. As well, country-specific studies should measure the minimum age at which childbearing for teens has similar associations

  10. Age-dependent electroencephalogram (EEG) patterns during sevoflurane general anesthesia in infants

    PubMed Central

    2015-01-01

    Electroencephalogram (EEG) approaches may provide important information about developmental changes in brain-state dynamics during general anesthesia. We used multi-electrode EEG, analyzed with multitaper spectral methods and video recording of body movement to characterize the spatio-temporal dynamics of brain activity in 36 infants 0–6 months old when awake, and during maintenance of and emergence from sevoflurane general anesthesia. During maintenance: (1) slow-delta oscillations were present in all ages; (2) theta and alpha oscillations emerged around 4 months; (3) unlike adults, all infants lacked frontal alpha predominance and coherence. Alpha power was greatest during maintenance, compared to awake and emergence in infants at 4–6 months. During emergence, theta and alpha power decreased with decreasing sevoflurane concentration in infants at 4–6 months. These EEG dynamic differences are likely due to developmental factors including regional differences in synaptogenesis, glucose metabolism, and myelination across the cortex. We demonstrate the need to apply age-adjusted analytic approaches to develop neurophysiologic-based strategies for pediatric anesthetic state monitoring.

    Whether intraventricular hemorrhage increases the risk of adverse developmental outcome among premature infants is controversial. Using brain ultrasound, we identified IVH and white matter abnormalities among 1064 infants born before 28 weeks gestation. We identified adverse developmental outcomes at 24 months of age using a standardized neurological examination and the Bayley Scales of Infant Development Mental and Motor Scales. In logistic regression models that adjusted for gestational age, sex, and public insurance, isolated intraventricular hemorrhage was associated with visual fixation difficulty (odds ratio: 2.5 (95% confidence limits: 1.2, 5.1)) but no other adverse outcome. Infants who had a white matter lesion unaccompanied by intraventricular hemorrhage were at increased risk of cerebral palsy, low Mental and Motor Scores, and visual and hearing impairments. Except when accompanied or followed by a white matter lesion, intraventricular hemorrhage is associated with no more than a mild increase (and possibly no increase) in the risk of adverse developmental outcome during infancy.

    The role of maternal chronological age in prenatal and perinatal history, social support, and parenting practices of new mothers (N=335) was examined. Primiparas of 5-month-old infants ranged in age from 13 to 42 years. Age effects were zero, linear, and nonlinear. Nonlinear age effects were significantly associated up to a certain age with little or no association afterward; by spline regression, estimated points at which the slope of the regression line changed were 25 years for prenatal and perinatal history, 31 years for social supports, and 27 years for parenting practices. Given the expanding age range of first-time parents, these findings underscore the importance of incorporating maternal age as a factor in studies of parenting and child development. PMID:16942495

    Rapid growth during infancy is associated with increased risk of overweight and obesity and differences in weight gain are at least partly explained by means of infant feeding. The aim was to assess the associations between infant feeding practice in early infancy and body mass index (BMI) at 6 years of age. Icelandic infants (n = 154) were prospectively followed from birth to 12 months and again at age 6 years. Birth weight and length were gathered from maternity wards, and healthcare centers provided the measurements made during infancy up to 18 months of age. Information on breastfeeding practices was documented 0–12 months and a 24-h dietary record was collected at 5 months. Changes in infant weight gain were calculated from birth to 18 months. Linear regression analyses were performed to examine associations between infant feeding practice at 5 months and body mass index (BMI) at 6 years. Infants who were formula-fed at 5 months of age grew faster, particularly between 2 and 6 months, compared to exclusively breastfed infants. At age 6 years, BMI was on average 1.1 kg/m2 (95% CI 0.2, 2.0) higher among infants who were formula fed and also receiving solid foods at 5 months of age compared to those exclusively breastfed. In a high-income country such as Iceland, early introduction of solid foods seems to further increase the risk of high childhood BMI among formula fed infants compared with exclusively breastfed infants, although further studies with greater power are needed.

    Emerging evidence suggests that fetal environmental exposures impact on future development of obesity. The objectives of this study were to assess the relationships between (i) maternal insulin sensitivity and glucose tolerance status in pregnancy and (ii) early infant weight gain and adiposity in the first year of life. In this prospective cohort study, 301 women underwent oral glucose tolerance testing for assessment of glucose tolerance status and insulin sensitivity (IS(OGTT)) in pregnancy. Their infants underwent anthropometric assessment at 12 months of age, including determination of weight gain in the first year of life and sum of skinfold thickness (SFT), a measure of infant adiposity. Infant weight gain and sum of SFT at 12 months did not differ according to maternal glucose tolerance status. On univariate analyses, weight gain from 0 to 12 months and sum of SFT were negatively associated with maternal IS(OGTT) during pregnancy. On multiple linear regression analysis, negative independent predictors of weight gain from 0 to 12 months were maternal IS(OGTT) during pregnancy (t = -2.73; P = 0.007), infant female gender (t = -3.16; P = 0.002), and parental education (t = -1.98; P = 0.05), whereas white ethnicity was a positive independent predictor (t = 2.68; P = 0.008). Maternal IS(OGTT) (t = -2.7; P = 0.008) and parental education (t = -2.58; P = 0.01) were independent negative predictors of sum of SFT at 12 months. Independent of maternal glucose tolerance status, maternal insulin resistance during pregnancy is associated with increased infant weight gain and adiposity over the first year of life. Further longitudinal study to evaluate obesity in this group of children will increase our understanding of the contribution of the intrauterine environment to their long-term health.

    Background The Infant Aphakia Treatment Study (IATS) is a randomized trial comparing the treatment of unilateral congenital cataract with primary intraocular lens (IOL) implantation versus aphakic contact lens (CL). The purpose of this study was to compare the outcomes for infants with lens opacity associated with persistent fetal vasculature (PFV) to those without. Methods Retrospective subgroup analysis of grating visual acuity at 1 year of age and adverse events up to 1 year after surgery in eyes identified intraoperatively as having evidence of mild PFV from the IATS. Results Of 83 infants, 18 (22%: 11 CL, 7 IOL) had PFV. Median logMAR visual acuity was 0.88 for patients with PFV and 0.80 for patients without PFV (P = 0.46). One or more adverse events up to one year after surgery occurred in 12 infants (67%) with PFV and 30 infants (46%) without PFV (P = 0.18). The incidence of adverse events was significantly higher in patients with PFV compared to patients without PFV in the CL group (55% vs 20%, P = 0.049) but not in the IOL group (86% vs 71%, P = 0.65), possibly because all children receiving IOLs had higher rates of adverse events when compared to aphakic children (73% vs 29%, P < 0.001). Conclusions Aphakic infants with mild PFV treated with CL had a higher incidence of adverse events following lensectomy compared to children with other forms of unilateral congenital cataract; nevertheless, similar visual outcomes at one year after surgery were obtained.

    Ciprofloxacin is used in neonates with suspected or documented Gram-negative serious infections. Currently, its use is off-label partly because of lack of pharmacokinetic studies. Within the FP7 EU project TINN (Treat Infection in NeoNates), our aim was to evaluate the population pharmacokinetics of ciprofloxacin in neonates and young infants <3 months of age and define the appropriate dose in order to optimize ciprofloxacin treatment in this vulnerable population. Blood samples were collected from neonates treated with ciprofloxacin and concentrations were quantified by high-pressure liquid chromatography–mass spectrometry. Population pharmacokinetic analysis was performed using NONMEM software. The data from 60 newborn infants (postmenstrual age [PMA] range, 24.9 to 47.9 weeks) were available for population pharmacokinetic analysis. A two-compartment model with first-order elimination showed the best fit with the data. A covariate analysis identified that gestational age, postnatal age, current weight, serum creatinine concentration, and use of inotropes had a significant impact on ciprofloxacin pharmacokinetics. Monte Carlo simulation demonstrated that 90% of hypothetical newborns with a PMA of <34 weeks treated with 7.5 mg/kg twice daily and 84% of newborns with a PMA ≥34 weeks and young infants receiving 12.5 mg/kg twice daily would reach the AUC/MIC target of 125, using the standard EUCAST MIC susceptibility breakpoint of 0.5 mg/liter. The associated risks of overdose for the proposed dosing regimen were <8%. The population pharmacokinetics of ciprofloxacin was evaluated in neonates and young infants <3 months old, and a dosing regimen was established based on simulation. PMID:25155587

    The aim of this study was to evaluate KL-6 and CC16 levels and their correlation with neurodevelopmental outcome among very low birth weight pre-term infants at 12 months corrected age. This prospective cohort study was performed from 2011 to 2013 by enrolling pre-term neonates of gestational age ≤ 32 weeks and birth weight ≤ 1500 g. Serum KL-6 and CC16 levels were determined 7 days after birth and their correlation with neurodevelopment was evaluated using Gesell Mental Developmental Scales. Of the 86 eligible pre-term infants, 63 completed follow-up, of which 15 had bronchopulmonary dysplasia. At 12 months corrected age, 49 infants had favorable outcomes and 14 infants had poor neurodevelopmental outcome. KL-6 levels were higher and CC16 levels were lower in infants with poor neurodevelopmental outcome compared with those infants who had favourable neurodevelopmental outcome. Serum KL-6 levels less than 90.0 ng/ml and CC16 levels greater than 320.0 pg/ml at 7 days of life were found to be predictive of a favourable outcome at 12 months corrected age. These biological markers could predict neurodevelopmental outcome at 12 months corrected age in very low birth weight premature infants, and help the clinician plan early therapeutic interventions to minimize or avoid poor neurodevelopmental outcome.

    Caffeine is consumed in various forms during pregnancy, has increased half-life during pregnancy and crosses the placental barrier. Small for gestational age (SGA) is an important perinatal outcome and has been associated with long term complications. We examined the association between maternal caffeine intake and SGA using National Birth Defects Prevention Study data. Non-malformed live born infants with an estimated date of delivery from 1997-2007 (n = 7,943) were included in this analysis. Maternal caffeine exposure was examined as total caffeine intake and individual caffeinated beverage type (coffee, tea, and soda); sex-, race/ethnic-, and parity-specific growth curves were constructed to estimate SGA births. Crude and adjusted odds ratios (aORs) and 95% confidence intervals were estimated using unconditional logistic regression. Interaction with caffeine exposures was assessed for maternal smoking, vasoconstrictor medication use, and folic acid. Six hundred forty-eight infants (8.2%) were found to be SGA in this analysis. Increasing aORs were observed for increasing intakes of total caffeine and for each caffeinated beverage with aORs (adjusting for maternal education, high blood pressure, and smoking) ranging from 1.3 to 2.1 for the highest intake categories (300+ mg/day total caffeine and 3+ servings/day for each beverage type). Little indication of additive interaction by maternal smoking, vasoconstrictor medication use, or folic acid intake was observed. We observed an increase in SGA births for mothers with higher caffeine intake, particularly for those consuming 300+ mg of caffeine per day. Increased aORs were also observed for tea intake but were more attenuated for coffee and soda intake.

    Mother-infant interaction of 14 teen-age mothers and their six-month-old infants was observed in the home and compared with that of 12 women 20 years or older and their infants. A further group was designated a "noncontact" group and was seen only at the beginning and end of the first year and was a control for research intervention or experimenter effects. Teen-agers showed few significant differences from older mothers in their mothering skills as measured by simple frequency distributions of individual behaviors and social interaction. Transitional probabilities and flow of interaction matrixes also revealed few significant differences. Like previous studies, the present study found that teen-age mothers showed high warmth and physical interaction but low verbal interaction with their infants. Support of the mothers through experience in the observational sessions may have influenced the results. The possibility is noted of differences in patterns of mothering as the infant develops.

    To investigate effects of visual experience versus preprogrammed mechanisms on visual development, we used multiple regression analysis to determine the extent to which a variety of variables (that differ in the extent to which they are tied to visual experience) predict luminance and chromatic (red/green) contrast sensitivity (CS), which are mediated by the magnocellular (M) and parvocellular (P) subcortical pathways, respectively. Our variables included gestational length (GL), birth weight (BW), gender, postnatal age (PNA), and birth order (BO). Two-month-olds (n = 60) and 6-month-olds (n = 122) were tested. Results revealed that (1) at 2 months, infants with longer GL have higher luminance CS; (2) at both ages, CS significantly increases over a approximately 21-day range of PNA, but this effect is stronger in 2- than 6-month-olds and stronger for chromatic than luminance CS; (3) at 2 months, boys have higher luminance CS than girls; and (4) at 2 months, firstborn infants have higher CS, while at 6 months, non-firstborn infants have higher CS. The results for PNA/GL are consistent with the possibility that P pathway development is more influenced by variables tied to visual experience (PNA), while M pathway development is more influenced by variables unrelated to visual experience (GL). Other variables, including prenatal environment, are also discussed.

    1990-09-01

    In this prospective study of 442 infants younger than 8 weeks of age who attended a pediatric emergency department with temperature greater than or equal to 100.6 degrees F (38.1 degrees C), urinary tract infections (UTIs) were found in 33 patients (7.5%), 2 of whom were bacteremic. Clinical and laboratory data were not helpful for identifying UTIs. Of the 33 patients with UTIs, 32 had urinalyses recorded; 16 were suggestive of a UTI (more than five white blood cells per high-power field or any bacteria present). Of the 16 infants with apparently normal urinalysis results, three had an emergency department diagnosis suggesting an alternative bacterial focus of infection. If the physician had decided on the basis of apparently normal urinalysis results to forgo obtaining a urine culture, more than half of the UTIs would have been missed. Bag-collected specimens were significantly more likely to yield indeterminate urine culture results than either catheter or suprapubic specimens. In addition, uncircumcised males were significantly more likely to have a UTI than circumcised boys. These results suggest that a suprapubic or catheter-obtained urine specimen for culture is a necessary part of the evaluation of all febrile infants younger than 8 weeks of age, regardless of the urinalysis findings or another focus of presumed bacterial infection.

    Coordination between perception and action is required to interact with the environment successfully. This is already trained by very young infants who perform spontaneous movements to learn how their body interacts with the environment. The strategies used by the infants for this purpose change with age. Therefore, very early progresses in action control made by the infants can be investigated by monitoring the development of spontaneous motor activity. In this paper, an objective method is introduced, which allows the quantitative evaluation of the development of spontaneous motor activity in newborns. The introduced methodology is based on the acquisition of spontaneous movement trajectories of the feet by 3D movement analysis and subsequent calculation of specific movement parameters from them. With these movement-based parameters, it was possible to provide an objective description of age-dependent developmental steps in healthy newborns younger than 6 months. Furthermore, it has been shown that pathologies like infantile cerebral palsy influence development of motor activity significantly. Since the introduced methodology is objective and quantitative, it is suitable to monitor how newborns train their cognitive processes, which will enable them to cope with their environment by motor interaction.

    To investigate effects of visual experience versus preprogrammed mechanisms on visual development, we used multiple regression analysis to determine the extent to which a variety of variables (that differ in the extent to which they are tied to visual experience) predict luminance and chromatic (red/green) contrast sensitivity (CS), which are mediated by the magnocellular (M) and parvocellular (P) subcortical pathways, respectively. Our variables included gestational length (GL), birth weight (BW), gender, postnatal age (PNA), and birth order (BO). Two-month-olds (n = 60) and 6-month-olds (n = 122) were tested. Results revealed that (1) at 2 months, infants with longer GL have higher luminance CS; (2) at both ages, CS significantly increases over a ~21-day range of PNA, but this effect is stronger in 2- than 6-month-olds and stronger for chromatic than luminance CS; (3) at 2 months, boys have higher luminance CS than girls; and (4) at 2 months, firstborn infants have higher CS, while at 6 months, non-firstborn infants have higher CS. The results for PNA/GL are consistent with the possibility that P pathway development is more influenced by variables tied to visual experience (PNA), while M pathway development is more influenced by variables unrelated to visual experience (GL). Other variables, including prenatal environment, are also discussed. PMID:19810800

    To test the hypothesis that characteristics of perinatal infection are associated with long-term cognitive limitations among preterm infants, we analyzed data from 294 infants (142 females, 152 males) < or = 1500 g birthweight and <37 completed weeks of gestation who were examined at age 9 years. We identified 47 children (20 females, 27 males) who had a non-verbal Kaufman Assessment Battery for Children (K-ABC) scale standard value below 70, i.e. more than 2 SDs below the age-adjusted mean. The 247 children (122 females, 125 males) with a score > or = 70 served as control participants. Maternal nationality and education, and low gestational age were significantly associated with a K-ABC non-verbal standard value <70. Both neonatal brain damage (intraventricular hemorrhage) and long-term sequelae (cerebral palsy [CP], diagnosed at age 6 years) were significantly associated with a below-normal non-verbal K-ABC score. Maternal fever at birth was present in five cases (11%) and eight controls (3%; odds ratio 3.6, 95% confidence interval 1.1 to 11.4). Clinical chorioamnionitis and preterm labor and/or premature rupture of membranes (as opposed to toxemia and other initiators of preterm delivery) were also more common among cases than control participants. When adjusting for potential confounders such as gestational age, maternal education and nationality, and CP, the risk estimate for maternal fever remained unchanged (3.8, 0.97 to 14.6). We conclude that perinatal infection might indeed contribute to an increased risk for long-term cognitive deficits in preterm infants. PMID:12613769

    This study aimed to assess the nutritional status of infants aged 0 to 5 months by different feeding approaches. A cross-sectional study on infant nutrition was performed in eight cities in China. A total of 622 infants from birth to 2 months of age and 456 infants from 3 months to 5 months of age were included in this study. Mix-fed infants received breast milk and complementary foods from birth to 2 months of age. Approximately 38.2% of mix-fed infants received excessive vitamin A, and 15.6% of infants exceeded the tolerable upper intake levels (ULs) of zinc. For artificially fed infants who received only complementary foods, approximately 20% and 12.5% infants received inadequate dietary vitamin A and zinc intakes, respectively. The vitamin A and zinc intakes of half of the infants exceeded the ULs. Results showed that the usual intake distribution of the infants from 3 months to 5 months of age were similar to that of the infants from birth to 2 months of age. The common vitamin A and zinc intakes were also severely imbalanced. In addition, higher disease prevalence and lower Z scores of length-forage, weight-for-age, and weight-for-length were found in artificially fed infants and mix-fed infants compared with those in breast-fed infants. In conclusion, the usual nutrient intakes were adequate for the majority of Chinese infants, except for an important number of infants at risk for imbalance of vitamin A and zinc intakes.

    Aim: This study is aimed to investigate differences between cognitive, language and motor development of high-risk infants related to birth weight and gestational age. Material and Methods: One hundred sixty high-risk infants who were born 32 weeks, 1 500 gr and below included in this study. According to corrected age, 58 infants were 1 month, 72 were at 4 months, 82 were at 8 months and 65 were 12 months old. Infants were seperated two groups according to gestational age <30 weeks and 30–32 weeks and birth weight ≤1 000 gr and 1 001–1 500 gr. Infants motor development were assessed with Bayley-III Infant and Toddler Development Motor Scale (Bayley-III) and Neuro Sensory Motor Developmental Scale (NSMDA), cognitif and lanuage development were Bayley-III cognitive and Language scales. Assessments were applied by the same physiotherapist at 1 month, 4 months, 8 months and 12 months old infants in corrected age. Mann-Whitney U Test, 2 x 2 Chi-Square test ve Fisher’s exact tests were used to compare group data. Statistical significance was determined p<0.05. Results: Cognitive, motor and language developments were in normal ranges in all infants. There were no statistical differences in cognitive, language and motor development between groups (p>0.05). Conclusion: Results of this study showed that the motor, cognitive and language development were normal in all high risk infants and power gestational age and birth weight did not affect these parametes.

    We evaluated the growth patterns of infants born large-for-gestational-age (LGA) from birth to age 1 year compared to those born appropriate-for-gestational-age (AGA). In addition, we investigated possible epigenetic changes associated with being born LGA. Seventy-one newborns were classified by birth weight as AGA (10th–90th percentile; n = 42) or LGA (>90th percentile; n = 29). Post-natal follow-up until age 1 year was performed with clinical assessments at 3, 6, and 12 months. Genome-wide DNA methylation was analysed on umbilical tissue in 19 AGA and 27 LGA infants. At birth, LGA infants had greater weight (p < 0.0001), length (p < 0.0001), ponderal index (p = 0.020), as well as greater head (p < 0.0001), chest (p = 0.044), and abdominal (p = 0.007) circumferences than AGA newborns. LGA infants were still larger at the age of 3 months, but by age 6 months there were no more differences between groups, due to higher length and weight increments in AGA infants between 0 and 6 months (p < 0.0001 and p = 0.002, respectively). Genome-wide analysis showed no epigenetic differences between LGA and AGA infants. Overall, LGA infants had slower growth in early infancy, being anthropometrically similar to AGA infants by 6 months of age. In addition, differences between AGA and LGA newborns were not associated with epigenetic changes. PMID:26419812

    OBJECTIVES: Congenital cytomegalovirus (cCMV) is the most common congenital infection; however, the epidemiology in Canada has not been recently examined. The present prospective study pilots tools for a population-based study of cCMV infection in Canada by determining the maternal seroprevalence and risk factors, the clinical characteristics and the incidence of cCMV using a variety of diagnostic tests in a cohort of high-risk infants in northern Alberta. METHODS: All infants born at the Royal Alexandra Hospital in Edmonton, Alberta, from June 1, 2003, to May 31, 2004, were screened for the study. Eligible infants were those with very low birth weights (VLBWs) or small for gestational age (SGA). Maternal CMV serostatus was determined, and chart review and parental interviews were completed. Neonatal urine and throat cultures, and polymerase chain reaction (PCR) were performed. Dried blood spots (DBS) were tested for CMV by PCR. RESULTS: In total, 213 infants were eligible for the study. Of these, 137 entered the study (79 VLBW and 58 SGA). Some families were not contacted for participation in the study due to neonatal deaths or early discharge. The mean age of the mothers was 27.6 years; 68% of the mothers were Caucasian and 16% were Aboriginal. The maternal CMV seroprevalence was 55%. Seropositivity was significantly associated with ethnicity (First Nations [100%]; Caucasian [34%]) and country of birth (outside Canada [94%]; Canadian born [45%]). The rate of cCMV was two in 137 (1.5%), with a rate of one in 79 (1.3%) for the VLBW infants and one in 58 (1.7%) for the SGA infants. Both had positive throat or urine specimens, but only the symptomatic infant was positive on DBS. CONCLUSIONS: A cCMV screening program should be universal and routine to successfully screen all newborns. Maternal CMV seropositivity varies widely within the Canadian population. In the present pilot study, DBS PCR was not a sensitive screening tool and throat swab was the best screening

    Maternal depression and anxiety represent risk factors for the quality of early mother-preterm infant interactions, especially in the case of preterm birth. Despite the presence of many studies on this topic, the comorbidity of depressive and anxious symptoms has not been sufficiently investigated, as well as their relationship with the severity of prematurity and the quality of early interactions. The Aim of this study was to evaluate the quality of early mother-infant interactions and the prevalence of maternal depression and anxiety comparing dyads of extremely low birth weight (ELBW) and very low birth weight (VLBW) preterm infants with full-term ones. Seventy seven preterm infants (32 ELBW; 45 VLBW) and 120 full term (FT) infants and their mothers were recruited. At 3 months of corrected age, 5 min of mother-infant interactions were recorded and later coded through the Global Ratings Scales. Mothers completed the Edinburgh Postnatal Depression Scale and Penn State Worry Questionnaire. Infant levels of development were assessed through the Griffiths Mental Development Scales. A relation emerged among the severity of prematurity, depression, anxiety, and the quality of interactions. When compared with the FT group, the ELBW interactions were characterized by high maternal intrusiveness and low remoteness, while the VLBW dyads showed high levels of maternal sensitivity and infant communication. Depression was related to maternal remoteness and negative affective state, anxiety to low sensitivity, while infant interactive behaviors were impaired only in case of comorbidity. ELBW’s mothers showed the highest prevalence of depressive and anxious symptoms; moreover, only in FT dyads, low maternal sensitivity, negative affective state and minor infant communication were associated to the presence of anxious symptoms. The results confirmed the impact of prematurity on mother–infant interactions and on maternal affective state. Early diagnosis can help to plan

    Manganese nutrition of the neonate is poorly understood, due in part to a paucity of information on the amount and availability of manganese in infant foods. We have developed a suckling pup model to assess the uptake of manganese from fluid diets by using extrinsic labeling. Human milk, cow milk and infant formulas were fed by intubation to fasted rat pups and adults. Rats were killed after varying time periods, and tissues were removed and counted. A period of 6 h was found to be adequate to allow for stomach emptying while limiting tissue redistribution; 24 h was found to reflect pup manganese retention. From human milk, manganese retention was highest (greater than or equal to 80%) in pups less than or equal to 15 days of age; in older pups average retention decreased to 40%. Using d 14 pups to assess relative Mn uptake from diets, wholebody Mn uptake was highest from cow milk (approximately 89%); uptake from human and cow milk formula was similar (approximately 80%) whereas it was lower from soy formula (approximately 60%). These findings suggest that bioavailability of Mn from infant diets is very high during the suckling period. Since most formulas contain considerably more manganese than is found in human milk, Mn deficiency may be less of a concern than possible toxicity from formulas.

    Sonar biparietal diameter, femur length, abdominal circumference, femur length/abdominal circumference ratio, ponderal index, and estimated fetal weight were obtained within ten days of delivery of small-for-gestational-age (SGA) (N = 102) and non-SGA (N = 204) newborns. The effectiveness of each ultrasound variable in the antenatal recognition of the SGA fetus was assessed. An abnormal abdominal circumference was the best predictor, confirming SGA in 98% of cases. Other variables (biparietal diameter, femur length, femur length/abdominal circumference ratio, ponderal index, or estimated fetal weight) were less accurate for predicting SGA. When we determined expected results based on a 10% prevalence of SGA, negative predictive value was greater than 92% for all variables studied; however, with the exception of estimated fetal weight and femur length, positive predictive values were disappointing, including abdominal circumference (21%). This report establishes the limits of ultrasound-derived growth variables in the antenatal identification of the SGA fetus.

    The purpose of this study was to assess the onset of independent ambulation relative to possible relationships with maternal and infant characteristics. In a cross-sectional study, the health files of 1,553 Turkish children aged 12-23 months were selected by the multistage sampling method in the Nomenclature of Territorial Units for Statistics (NUTS) regions coded as low, medium and high malnutrition levels in Turkey. Children were selected from health centers by systematic sampling technique in each region. Kaplan-Meier analysis and estimated mean values were used for data description; log-rank test and the Cox multivariable regression analysis were applied for data analysis. Maternal education level, occupation, region of residence, gestational iron supplementation, child's gender, child's nutritional status, and presence of anemia in the infant during the survey period demonstrated significant relationships with walking unassisted in the univariate analysis. However, multivariable analysis showed that high maternal education, absence of parental consanguinity and appropriate weight-for-age Z score were positively associated with earlier age of walking. These findings showed the importance of improvement in girls' education, prevention of postnatal growth retardation and improvement in diet quality for children's gross motor development. In addition, counseling programs should be given to decrease the rate of parental consanguinity.

    To determine the incidence of otitis media (OM) and the bacteriology of acute otitis media (AOM) in a clinic population of young children in Pittsburgh, 138 black infants and 60 white infants were followed from birth to 2 years of age, examined at monthly intervals and whenever an upper respiratory tract infection (URI) or OM intervened. By 24 months of age the cumulative incidence of episodes of AOM was 43% and 42%, and of episodes of middle-ear effusion (MEE) was 86% and 85% in black and white infants, respectively. The average rate of episodes of AOM was 0.41 and 0.39 and of episodes of MEE was 1.68 and 1.70 in black and white infants, respectively. Tympanocentesis was performed for episodes of AOM and the following organisms were isolated from black and white infants, respectively: Streptococcus pneumoniae 43% and 43% of episodes; Moraxella catarrhalis 24% and 24%; non-typable Haemophilus influenzae 18% and 24%; and Haemophilus influenzae type b 5% and 0%. In both black and white infants first born children had less ear disease. We found no difference in the incidence of otitis media during the first 2 years of life between black and white infants.

    OBJECTIVE The objective of the study was to examine fetal/infant mortality by gestational age at term stratified by maternal age. STUDY DESIGN A retrospective cohort study was conducted using 2005 US national birth certificate data. For each week of term gestation, the risk of mortality associated with delivery was compared with composite mortality risk of expectant management. The expectant management measure included stillbirth and infant death. This expectant management risk was calculated to estimate the composite mortality risk with remaining pregnant an additional week by combining the risk of stillbirth during the additional week of pregnancy and infant death risk following delivery at the next week. Maternal age was stratified by 35 years or more compared with women younger than 35 years as well as subgroup analyses of younger than 20, 20–34, 35–39, or 40 years old or older. RESULTS The fetal/infant mortality risk of expectant management is greater than the risk of infant death at 39 weeks’ gestation in women 35 years old or older (15.2 vs 10.9 of 10,000, P < .05). In women younger than 35 years old, the risk of expectant management also exceeded that of infant death at 39 weeks (21.3 vs 18.8 of 10,000, P < .05). For women younger than 35 years old, the overall expectant management risk is influenced by higher infant death risk and does not rise significantly until 41 weeks compared with women 35 years old or older in which it increased at 40 weeks. CONCLUSION Risk varies by maternal age, and delivery at 39 weeks minimizes fetal/infant mortality for both groups, although the magnitude of the risk reduction is greater in older women.

    Influenza is a serious problem for infants <6 months of age, whose hospitalization rates for influenza and associated illness are comparable with rates in the elderly. Because influenza vaccines are not effective in this age group, the optimal evidence-based strategy is to administer trivalent inactivated influenza vaccines during pregnancy. Immunizing with trivalent inactivated influenza vaccines in the second and third trimester is well studied and safe, not only providing protection for the pregnant woman and her infant <6 months of age, but also for the fetus by decreasing the risk for low birth weight.

    Purpose To determine whether stereopsis of infants treated for monocular cataracts varies with the type of optical correction used. Design Randomized prospective clinical trial Methods The Infant Aphakia Treatment Study randomized 114 patients with unilateral cataracts at age 1 to 7 months to either primary intraocular lens (IOL) or contact lens correction. At 4.5 years of age a masked examiner assessed stereopsis on these patients using three different tests: 1) Frisby; 2) Randot Preschool; and 3) Titmus fly. Results Twenty-eight patients (25%) had a positive response to at least one of the stereopsis tests. There was no statistically significant difference in stereopsis between the two treatment groups. Frisby (contact lens, 6 (11%); IOL, 7 (13%); p=0.99), Randot (contact lens, 3 (6%); IOL, 1 (2%); p=0.62) or Titmus: (contact lens, 8 (15%); IOL, 13 (23%); p=0.34). The median age at surgery for patients with stereopsis was younger than for those without stereopsis (1.2 versus 2.4 months; p=0.002). The median visual acuity for patients with stereopsis was better than for those without stereopsis (20/40 vs. 20/252; p=0.0003). Conclusion The type of optical correction did not influence stereopsis outcomes. However, two other factors did: age at surgery and visual acuity in the treated eye at age 4.5 years. Early surgery for unilateral congenital cataract and the presence of visual acuity better than or equal to 20/40 appear to be more important than the type of initial optical correction used for the development of stereopsis.

    Temperamental regulatory competence and social communication in term and preterm infants at 12 months corrected age was studied in a randomized controlled intervention trial aimed at enhancing maternal sensitive responsiveness. Surviving infants <2000 g from a geographically defined area were randomized to an intervention (71) or a control group (69), and compared with term infants (74). The intervention was a modified version of the "Mother-Infant Transaction Program". Regulatory competence was measured with the Infant Behavior Questionnaire, and social communication with the Early Social Communication Scales. Preterm intervention infants with low regulatory competence had higher responding to joint attention than preterm control infants. A sensitizing intervention may moderate the association between temperament and social communication, and thus allow an alternative functional outlet for preterm infants low in regulatory competence. The finding may have implications for conceptualizations of the role of early sensitizing interventions in promoting important developmental outcomes for premature infants.

    Human cortical folding is believed to correlate with cognitive functions. This likely correlation may have something to do with why abnormalities of cortical folding have been found in many neurodevelopmental disorders. However, little is known about how cortical gyrification, the cortical folding process, develops in the first 2 years of life, a period of dynamic and regionally heterogeneous cortex growth. In this article, we show how we developed a novel infant-specific method for mapping longitudinal development of local cortical gyrification in infants. By using this method, via 219 longitudinal 3T magnetic resonance imaging scans from 73 healthy infants, we systemically and quantitatively characterized for the first time the longitudinal cortical global gyrification index (GI) and local GI (LGI) development in the first 2 years of life. We found that the cortical GI had age-related and marked development, with 16.1% increase in the first year and 6.6% increase in the second year. We also found marked and regionally heterogeneous cortical LGI development in the first 2 years of life, with the high-growth regions located in the association cortex, whereas the low-growth regions located in sensorimotor, auditory, and visual cortices. Meanwhile, we also showed that LGI growth in most cortical regions was positively correlated with the brain volume growth, which is particularly significant in the prefrontal cortex in the first year. In addition, we observed gender differences in both cortical GIs and LGIs in the first 2 years, with the males having larger GIs than females at 2 years of age. This study provides valuable information on normal cortical folding development in infancy and early childhood. PMID:24647943

    Children adopted from China represent the single largest group of internationally adopted children in this country. Because the adoptive families typically do not speak any Chinese language or dialect, most of these children experience an abrupt shift in their language environment. How age of adoption affects the course of English language development of children adopted from China is the focus of this study. All of the children in this study were either infants or toddlers at the time of adoption and all came from the same orphanage. The results showed that the older children (toddlers) were at both an advantage and a disadvantage when it came to English language development. The advantage of being older was that they learned faster. The disadvantage of being older was that there was more for them to learn to become age-appropriate in their English language development. There was, however, no evidence to suggest that the language switch from a Chinese- to an English-language environment was a formidable obstacle for either the infants or the toddlers.

    Weight gain, nitrogen balance, protein turnover, and energy and protein intakes were measured during the first week of life of 14 low-birth-weight (LBW) infants, 5 small-for-gestational-age (SGA) infants and 9 appropriate-for-gestational-age (AGA) infants enterally fed at rates determined by the infants ability to assimilate feed. Mean gross intakes were 334 KJ and 1.75 g/kg protein; 4 infants were increasing and 10 were losing weight at rates proportional to gross energy and protein intakes and to nitrogen balance (0.031 g protein balance/g wt gain). Rates of protein synthesis and degradation measured by an intragastric infusion of [1-13C]leucine, averaged 14.5 and 15.9 g protein.kg-1.d-1, some 50% higher than previously reported in older preterm infants and not correlated with nitrogen balance. The growth failure of these infants was not associated with inadequate overall rates of protein turnover, but appeared to reflect an influence of the insufficient energy and protein intakes on the high rates of protein turnover, inducing changes in protein balance in either direction through relatively small changes in protein synthesis and/or degradation.

    Studies of infants at risk for autism spectrum disorder (ASD) have proliferated, but few of these samples have been followed longer-term. We conducted a follow-up study, at age 5.5-9 years, of younger siblings of children with ASD (high-risk group, n = 79) or typical development (low-risk group, n = 60), originally recruited as infants. Children with ASD were excluded because of the focus on understanding the range of non-ASD outcomes among high-risk siblings. Using examiner ratings, parent ratings, and standardized assessments, we evaluated differences in clinical outcomes, psychopathology symptoms, autism symptoms, language skills, and nonverbal cognitive abilities. After adjusting for covariates, the high-risk group had increased odds of any clinically elevated/impaired score across measures relative to the low-risk group (43% vs. 12%, respectively). The high-risk group also had increased odds of examiner-rated Clinical Concerns (CC) outcomes (e.g., ADHD concerns, broader autism phenotype, speech-language difficulties, anxiety/mood problems, learning problems) relative to the low-risk group (38% vs. 13%, respectively). The high-risk group with CC outcomes had higher parent-reported psychopathology and autism symptoms, and lower directly-assessed language skills, than the Low-Risk Typically Developing (TD) and High-Risk TD groups, which did not differ. There were no differences in nonverbal cognitive skills. For some in the high-risk group, clinical concerns persisted from early childhood, whereas for others clinical concerns were first evident at school-age. Results suggest continued vulnerability in at least a subgroup of school-age children with a family history of ASD and suggest that this population may benefit from continued screening and monitoring into the school-age years.

    ABSTRACT This study investigated whether lower vagal function in preterm infants is associated with increased fundamental frequency (F 0; frequency of vocal fold vibration) of their spontaneous cries. We assessed respiratory sinus arrhythmia (RSA) during quiet sleep as a measure of vagal function, and its relationship with the F 0 of spontaneous cries in healthy preterm and term infants at term‐equivalent age. The results showed that preterm infants have significantly lower RSA, and higher overall F 0 than term infants. Moreover, lower RSA was associated with higher overall F 0 in preterm infants, whereas higher RSA was positively associated with mean and maximum F 0, and a larger F 0 range in term infants. These results suggest that individual differences in vagal function may be associated with the F 0 of spontaneous cries via modulation of vocal fold tension in infants at an early developmental stage. © 2016 The Authors.

    Low-level mercury (Hg) exposure in infancy might be harmful to the physical growth as well as neurodevelopment of children. The aim of this study was to investigate postnatal Hg exposure and its relationship with anthropometry and dietary factors in late infancy. We recruited 252 healthy Korean infants between six and 24 months of age from an outpatient clinic during the 2009/2010 and 2013/2014 seasons. We measured the weight and height of the infants and collected dietary information using questionnaires. The Hg content of the hair and blood was assessed using inductively coupled plasma mass spectroscopy. The geometric mean Hg concentration in the hair and blood was 0.22 (95% confidence interval: 0.20-0.24) µg/g and 0.94 (n = 109, 95% confidence interval: 0.89-0.99) µg/L, respectively. The hair Hg concentration showed a good correlation with the blood Hg concentration (median hair-to-blood Hg ratio: 202.7, r = 0.462, p < 0.001) and was >1 µg/g in five infants. The hair Hg concentration showed significant correlations with weight gain after birth (Z-score of the weight for age-Z-score of the birthweight; r = -0.156, p = 0.015), the duration (months) of breastfeeding as the dominant method of feeding (r = 0.274, p < 0.001), and the duration of fish intake more than once per week (r = 0.138, p = 0.033). In an ordinal logistic regression analysis with categorical hair Hg content (quartiles), dietary factors, including breastfeeding as the dominant method of feeding in late infancy (cumulative odds ratio: 6.235, 95% confidence interval: 3.086-12.597, p < 0.001) and the monthly duration of fish intake more than once per week (cumulative odds ratio: 1.203, 95% confidence interval: 1.034-1.401; p = 0.017), were significantly associated with higher hair Hg content. Weight gain after birth was not, however, significantly associated with hair Hg content after adjustment for the duration of breastfeeding as the dominant method of feeding.

    Background Preterm infants are at high risk of developing respiratory syncytial virus (RSV)-associated lower respiratory tract infection (LRTI). This observational epidemiologic study evaluated RSV disease burden and risk factors for RSV-associated LRTI hospitalization in preterm infants 33 weeks+0 days to 35 weeks+6 days gestational age not receiving RSV prophylaxis. Methods Preterm infants ≤6 months of age during RSV season (1 October 2013–30 April 2014) were followed at 72 sites across 23 countries from September 2013–July 2014 (study period). RSV testing was performed according to local clinical practice. Factors related to RSV-associated hospitalization for LRTI were identified using multivariable logistic regression with backward selection. Results Of the 2390 evaluable infants, 204 and 127 were hospitalized for LRTI during the study period and RSV season, respectively. Among these subjects, 64/204 and 46/127, respectively, were hospitalized for confirmed RSV LRTI. Study period and RSV season normalized RSV hospitalization rates (per 100 infant years) were 4.1 and 6.1, respectively. Factors associated with an increased risk of RSV-related LRTI hospitalization in multivariable analyses were smoking of family members (P<0.0001), non-hemodynamically significant congenital heart disease diagnosis (P = 0.0077), maternal age of ≤25 years at delivery (P = 0.0009), low maternal educational level (P = 0.0426), household presence of children aged 4 to 5 years (P = 0.0038), age on 1 October ≤3 months (P = 0.0422), and presence of paternal atopy (P<0.0001). Conclusions During the 2013–2014 RSV season across 23 countries, for preterm infants 33–35 weeks gestation ≤6 months old on 1 October not receiving RSV prophylaxis, confirmed RSV LRTI hospitalization incidence was 4.1 per 100 infant years during the study period and 6.1 per 100 infant years during the RSV season.

    In a study of 1,002 consecutive Malaysian male newborns, 48 (4.8%) were found to have undescended testes (UDT). The rate and laterality of the UDT were associated with lower birth weight (P < 0.001) and prematurity (P < 0.001). Boys with UDT were also more likely to have other congenital abnormalities of the external genitalia, the commonest being hydrocele. No correlation between UDT and maternal age, birth order, social class, or mode of delivery was demonstrated in this study. Although 26/34 (76.5%) of UDT achieved full spontaneous descent by 1 year of age, 1.1% of all infants whose testes remained undescended required regular long-term follow-up with surgical referral and correction at an appropriate time. A premature infant with UDT is more likely to achieve full testicular descent at 1 year of age than a term infant. PMID:9391202

    Background: Lead, mercury, cadmium and arsenic are some of the most common toxic metals to which Canadians are exposed. The effect of exposure to current low levels of toxic metals on fetal growth restriction is unknown. Objective: The aim of this study was to examine relationships between exposure to lead, mercury, cadmium and arsenic during pregnancy, and risk of small for gestational age (SGA) birth. Methods: Lead, mercury, cadmium and arsenic levels were measured in blood samples from the first and third trimesters in 1835 pregnant women from across Canada. Arsenic species in first trimester urine were also assessed. Relative risks and 95% confidence intervals were estimated using log binomial multivariate regression. Important covariates including maternal age, parity, pre-pregnancy BMI, and smoking, were considered in the analysis. An exploratory analysis was performed to examine potential effect modification of these relationships by single nucleotide polymorphisms (SNPs) in GSTP1 and GSTO1 genes. Results: No association was found between blood lead, cadmium or arsenic and risk for SGA. We observed an increased risk for SGA for the highest compared to the lowest tertile of exposure for mercury (>1.6 µg/L, RR=1.56.; 95% CI=1.04–2.58) and arsenobetaine (>2.25 µg/L, RR=1.65; 95% CI=1.10–2.47) after adjustment for the effects of parity and smoking. A statistically significant interaction was observed in the relationship between dimethylarsinic acid (DMA) levels in urinary arsenic and SGA between strata of GSTO1 A104A (p for interaction=0.02). A marginally significant interaction was observed in the relationship between blood lead and SGA between strata of GSTP1 A114V (p for interaction=0.06). Conclusions: These results suggest a small increase in risk for SGA in infants born to women exposed to mercury and arsenic. Given the conflicting evidence in the literature this warrants further investigation in other pregnant populations. - Highlights: • Metals

    The objective of this article is to describe growth of very low birth weight infants born in southern Brazil. All infants weighing < or =1500 g were followed up until 12 months corrected age (CA). Growth was recorded at 40 weeks, 6 and 12 months CA. Catch up was considered if the measures were > or =-2 SD of World Health Organization growth charts for weight and length; and of National Center for Health Statistics for head circumference. One hundred and ninety three infants born were followed up for the study. At 40 weeks CA, 57.8% patients achieved catch-up in weight and 50.9% in length. At 6 months CA, 82.2% achieved catch-up for weight and length and at 1 year CA, 92% achieved catch-up in weight and 86.9% in length. Catch-up in head circumference was achieved for 93.4%, 85.9% and 85% patients at 40 weeks, 6 months and 12 months CA, respectively. At 12 months CA, no catch-up in weight, length and head circumference was related to higher SNAPPE-II (P = 0.046) and periventricular leukomalacia (PVL) (P = 0.003); longer time to achieve full enteral nutrition at the neonatal intensive care unit (NICU) (P = 0.037), lower maternal education (P = 0.018) and PVL (P = 0,003); higher SNAPPE-II (P = 0,004), PVL (P = 0.005) and longer time to achieve full enteral nutrition at the NICU (P = 0.044), respectively. In conclusion, PVL and higher SNAPPE-II were important factors to catch-up delay. Catch-up growth was high at 12 months CA.

    Purpose To characterize the retinopathy of prematurity (ROP) and survival of infants born at gestational age (GA) of 22–25 weeks. Methods This study was a comparative case series for the total set of 78 infants ≤25 GA screened for ROP at a level IV NICU during a 21-month period. Data are presented on infants screened for ROP from 6 weeks after birth for 22 and 23 weeks’ GA infants and from 5 weeks after birth for 24 and 25 weeks’ GA. Accounting for the competing risk of mortality, we implemented Cox CR regression models to assess birth weight, GA, and admission diagnosis as potential risk factors for the following time to event outcomes: type 1 disease, aggressive posterior ROP (AP-ROP), plus disease, first presentation of ROP, and worst ROP observed. Results Risk of laser treatment (subhazard ratio [SHR] = 0.56, P = 0.007) and of plus disease (SHR = 0.49, P = 0.001) was increased among those born at lower GA. Twenty infants required laser for type 1 disease at median postmenstrual age (PMA) of 35.8 weeks (range, 33.0–42.7); infants with AP-ROP had laser at PMA of 34.5 weeks (range, 33.0–36.9), 2 weeks earlier than infants without AP-ROP at PMA 36.5 weeks (range, 33.9–42.7). The cumulative probability of receiving laser therapy approached 46% (22 or 23 weeks’ GA), 30% (24 weeks’ GA), and 18% (25 weeks’ GA). Conclusions This study confirms the 2013 screening guidelines appear to be appropriate for infants of 22 and 23 weeks’ GA when ROP screening begins at PMA 31 weeks. PMID:24924282

    Iodine is the main constituent of thyroid hormones, which in turn are required for fetal brain development. However, the relation between iodine intake during pregnancy, thyroid function, and child neurodevelopment needs further evaluation. The authors assessed the association of maternal iodine intake from diet and supplements during pregnancy and of maternal and neonatal thyroid function with infant neurodevelopment. The Mental Development Index and Psychomotor Development Index (PDI) for 691 children were obtained between 2005 and 2007 using the Bayley Scales of Infant Development at age 1 year in a prebirth cohort in Valencia, Spain. In multivariate analyses, a maternal thyrotropin level >4 μU/mL was associated with an increased risk of a PDI <85 (odds ratio = 3.5, P = 0.02). Maternal intake of ≥150 μg/day, compared with <100 μg/day, of iodine from supplements was associated with a 5.2-point decrease in PDI (95% confidence interval: -8.1, -2.2) and a 1.8-fold increase in the odds of a PDI <85 (95% confidence interval: 1.0, 3.3). When analyses were stratified by sex, this association was intensified for girls but was not observed for boys. Further evidence on the safety and effectiveness of iodine supplementation during pregnancy is needed before it is systematically recommended in iodine-sufficient or mildly deficient areas.

    In March 2014, the American Academy of Sleep Medicine (AASM) Board of Directors requested the Scoring Manual Editorial Board develop rules, terminology, and technical specifications for scoring sleep/wake states in full-term infants from birth to 2 mo of age, cognizant of the 1971 Anders, Emde, and Parmelee Manual for Scoring Sleep in Newborns. On July 1, 2015, the AASM published rules for scoring sleep in infants, ages 0–2 mo. This evidence-based review summarizes the background information provided to the Scoring Manual Editorial Board to write these rules. The Anders Manual only provided criteria for coding physiological and behavioral state characteristics in polysomnograms (PSG) of infants, leaving specific sleep scoring criteria to the individual investigator. Other infant scoring criteria have been published, none widely accepted or used. The AASM Scoring Manual infant scoring criteria incorporate modern concepts, digital PSG recording techniques, practicalities, and compromises. Important tenets are: (1) sleep/wake should be scored in 30-sec epochs as either wakefulness (W), rapid eye movement, REM (R), nonrapid eye movement, NREM (N) and transitional (T) sleep; (2) an electroencephalographic (EEG) montage that permits adequate display of young infant EEG is: F3-M2, F4-M1, C3-M2, C4-M1, O1-M2, O2-M1; additionally, recording C3-Cz, Cz-C4 help detect early and asynchronous sleep spindles; (3) sleep onsets are more often R sleep until 2–3 mo postterm; (4) drowsiness is best characterized by visual observation (supplemented by later video review); (5) wide open eyes is the most crucial determinant of W; (6) regularity (or irregularity) of respiration is the single most useful PSG characteristic for scoring sleep stages at this age; (7) trace alternant (TA) is the only relatively distinctive EEG pattern, characteristic of N sleep, and usually disappears by 1 mo postterm replaced by high voltage slow (HVS); (8) sleep spindles first appear 44–48 w

    Between May 1993, and September 1994, a randomized, blinded clinical trial was conducted to evaluate measures of growth and body composition in 63 (32 males; 31 females) healthy, low-birth-weight infants (940-2250 g) who were randomly assigned to an infant formula with docosahexaenoic acid (22:6n3, DHA, 0.2 wt%) from fish oil or to a control formula. A preterm formula with or without DHA was fed beginning at 7-10 days prior to hospital discharge through 43 weeks postmenstrual age (PMA). Then, from 43-59 weeks PMA, infants were fed a term infant formula with or without a corresponding amount of DHA. Growth (weight, length, head circumference), regional body fatness (triceps, subscapular, suprailiac skinfold thicknesses), circumferences (arm, abdominal, chest), and estimates of body composition determined by total body electrical conductivity (TOBEC) (fat-free mass [FFM]) were evaluated. Growth was slower in males fed the DHA formula. They had significantly (P < 0.05) smaller gains in weight, length, and head circumference between study enrollment to 59 weeks PMA than those fed the control formula. At 51 weeks PMA, males in the DHA group had significantly smaller head circumferences (P < 0.05) and lower FFM (P < 0.05). At 59 weeks PMA, males in the DHA group weighed less (P < 0.05), had shorter recumbent lengths (P < 0.01), smaller head circumferences (P < 0.05), and lower FFM (P < 0.01) than those fed the control formula. Energy intakes from formula (kcal/d), however, were lower at 51 weeks (P < 0.05) and 59 weeks (P < 0.05) PMA in males fed the DHA formula. Adjusted for body weight (kcal/kg/d), mean energy intakes from formula at 51 and 59 weeks PMA were not significantly different between feeding groups. The differences in recumbent length, head circumference, and FFM remained statistically significant after controlling for energy and protein intakes (P < 0.01). For all males, neither FFM nor total body fat (TBF), when expressed as a percentage of total body

    This longitudinal study of children enrolled as infants in the New York State (NYS) Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) examined predictors of obesity (body mass index ≥ 95th percentile) at 3 years of age. NYS WIC administrative data which included information from parent interviews and measured heights and weights for children were used. All 50,589 children enrolled as infants in WIC between July to December 2008 and July to December 2009 and retained in WIC through age three were included. At 3 years of age, 15.1% of children were obese. Multiple logistic regression analysis showed that children of mothers who received the Full Breastfeeding Food Package when their infant was enrolled in WIC (adjusted OR = 0.52) and children with ≤2 h screen time daily at age 3 (adjusted OR = 0.88) were significantly less likely to be obese (p < 0.001) controlling for race/ethnicity, birth weight, and birthplace. In this cohort of NYS WIC participants, maternal receipt of the Full Breastfeeding Food Package (a surrogate measure of exclusive breastfeeding) is associated with lower levels of obesity in their children at age 3. The relationships between participation in WIC, exclusive breastfeeding, and obesity prevention merit further study.

The study population consisted of 90 premature infants born between January 1, 2005, and December 31, 2011, who were tested using the ASQ (Korean) and Bayley Scales of Infant Development (BSID) (II) at a corrected age of 18-24 months. The validity of the ASQ (Korean) using cut-off values set at < -2 SD was examined by comparing it to the BSID (II) components, namely, the mental developmental index (MDI) or psychomotor developmental index (PDI), which were both set at < 85. The calculation of the sensitivities, specificities, positive predictive values, and negative predictive values of the ASQ (Korean) components revealed that they detected infants with neurodevelopmental delay with low sensitivity and positive predictive values, however, the communication domain showed moderate correlations with MDI. The failure in more than one domain of the ASQ (Korean) was significantly correlated with the failure in MDI. The ASQ (Korean) showed low validity for screening neurodevelopmentally delayed premature infants. PMID:25829813

    Between January 1974 and November 1980, 13 symptomatic infants under 1 year of age with persistent truncus arteriosus type I or II underwent surgery. Pulmonary artery banding was performed in 10 cases, with five deaths. Among the survivors, one developed severe pulmonary vascular disease and only two underwent late intracardiac repair. Primary total correction was performed in three infants and all are well, though one required conduit replacement five and a half years after the initial procedure. Recently, antibiotic sterilised homograft conduits, rather than heterografts, have been preferred as extracardiac conduits in infancy. Early intracardiac repair followed, if necessary, by later conduit replacement appears to have significant advantages over "conventional" pulmonary artery banding and late total correction.

    Studies of infant temperament are inconsistent with regard to convergence across measurement sources. In addition, little published work is available that describes temperament in minority infants. In this study, measures of temperament at three and six months were made for 24 African-American infants. Although maternal ratings of activity and…

    Close friendships become important at middle-school age and are unexplored in adolescents born prematurely. The study aimed to characterize friendship behaviors of formerly preterm infants at age 12 and explore similarities and differences between preterm and full-term peers on dyadic friendship types. From the full sample of N=186, one hundred sixty-six 12-year-old adolescents (40 born full term, 126 born preterm) invited a close friend to a 1.5 hour videotaped laboratory play session. Twenty adolescents were unable to participate due to scheduling conflicts or developmental disability. Characteristic friendship behaviors were identified by Q-sort followed by Q-factoring analysis. Friendship duration, age, and contact differed between the full-term and preterm groups but friendship activities, behaviors, and quality were similar despite school service use. Three Q-factors, leadership, distancing, and mutual playfulness, were most characteristic of all dyads, regardless of prematurity. These prospective, longitudinal findings demonstrate diminished prematurity effects at adolescence in peer friendship behavior and reveal interpersonal dyadic processes that are important to peer group affiliation and other areas of competence.

    This prospective study aimed to investigate the immune responses and safety of an influenza vaccine in vaccine-naïve infants aged 6-12 months, and was conducted from November 2010 to May 2011. Fifty-nine infants aged 6-12 months received two doses of trivalent inactivated influenza vaccine 4 weeks apart. Hemagglutination inhibition titers were measured 4 weeks after the two doses of study vaccine. Based on the assumption that a hemagglutination inhibition titer of 1:40 or greater against the antigen would be protective in adults, two doses of the study vaccine generated a protective immune response of 63.2% against influenza A(H1N1), 82.5% against influenza A(H3N2) and 38.6% against influenza B viruses in infants aged 6-12 months. The geometric mean fold rises against influenza type A and B viruses also met the European Medicines Agency criteria for flu vaccines. The solicited events within 7 days after vaccination were mild in intensity. No deaths or adverse events such as optic neuritis, cranial neuropathy, and brachial neuropathy or Guillain-Barre syndrome were reported. Two doses of inactivated influenza vaccine were well tolerated and induced a protective immune response against influenza in infants aged 6-12 months.

    For over 2 decades, dual-energy X-ray absorptiometry (DXA) has been the gold standard for estimating bone mineral density (BMD) and facture risk in adults. More recently DXA has been used to evaluate BMD in pediatrics. However, BMD is usually assessed against reference data for which none currently exists in infancy. A prospective study was conducted to assess bone mass of term infants (37 to 42 weeks of gestation), weight appropriate for gestational age, and born to healthy mothers. The group consisted of 33 boys and 26 girls recruited from the Winnipeg Health Sciences Center (Manitoba, Canada). Whole body (WB) as well as regional sites of the lumbar spine (LS 1–4) and femur was measured using DXA (QDR 4500A, Hologic Inc.) providing bone mineral content (BMC) for all sites and BMD for spine. During the year, WB BMC increased by 200% (76.0 ± 14.2 versus 227.0 ± 29.7 g), spine BMC by 130% (2.35 ± 0.42 versus 5.37 ± 1.02 g), and femur BMC by 190% (2.94 ± 0.54 versus 8.50 ± 1.84 g). Spine BMD increased by 14% (0.266 ± 0.044 versus 0.304 ± 0.044 g/cm2) during the year. This data, representing the accretion of bone mass during the first year of life, is based on a representative sample of infants and will aid in the interpretation of diagnostic DXA scans by researchers and health professionals.

    In 41 healthy human-milk-fed preterm infants the preprandial total bile acid (BA) concentrations in serum and duodenal juice were simultaneous measured during the first 60 days of life. The infants were subdivided into four groups according to their gestational age: 6 infants with a gestational age of 27 and 28 weeks, 7 infants with a gestational age of 29 and 30 weeks, 21 infants with a gestational age of 31 and 32 weeks and 7 infants with a gestational age of 33 and 34 weeks. The BA levels were enzymatically determined using 3-alpha-hydroxysteroid dehydrogenase. In the duodenal juice, cholic acid (CA), chenodeoxycholic acid (CDCA), deoxycholic acid and lithocholic acid were separately quantified by thin-layer chromatography. During the first month of life, the serum BA concentrations increased significantly with postnatal age (p < 0.01) but remained nearly constant during the second month of life. In the duodenal aspirates, the BA concentrations increased continuously up to the end of the observations period (p < 0.001). In the duodenal aspirates, the CA/CDCA ratio was high immediately after birth and decreased significantly with increasing postnatal age (p < 0.001). During the first weeks of life, the BA levels were preferentially conjugated with taurine, but in spite of the taurine-rich diet during the whole observation period the taurine/glycine ratio decreased with postnatal age (p < 0.001). In all samples of duodenal juice, the sum of primary BA was > 98% of total 3-alpha-hydroxy-BA. These data indicate that the establishment of an intestinal microbial flora necessary for intestinal BA transformation and the development of the enterohepatic BA circulation lasts some months of postnatal life. The serum BA concentration reflects hepatic synthesis, intestinal absorption, renal excretion and hepatocellular transport into bile in a very complex way which may limit the diagnostic value of serum BA during this time. Additionally, a duodenal BA concentration below 4

    This is a longitudinal study of development in coordinated mother-infant vocal interaction from 4 to 10 months (N = 41) focusing on the development of turn-taking patterns and time spent in coordinated vocal interaction. Data analyses were carried out using multistate analysis. Both mothers and infants were found to coordinate their own vocalizations with their partners' vocalizations. The infants had a predominant pattern of covocalizing, whereas the mothers had a predominant turn-taking pattern at all ages (4, 7, and 10 months). However, a significant reduction in the duration of covocalization was found between 4 and 7 months, due to less covocalizing compared to turn-taking from the infants. In addition, time spent in coordinated vocal interaction increased significantly between 4 and 7 months and a development for the infants was found from repeated vocalizations toward single vocalizations between maternal turns. Taken together, these findings indicate a developmental process of fine-tuning and increasing the turn-taking format for vocal communication, characterizing adult communication, before the development of speech. In addition, our results indicate that this development starts earlier and is more prolonged than has been hypothesized from previous research. (PsycINFO Database Record

    This study assessed the effect of delayed (1 minute after delivery) clamping of the umbilical cord on hemoglobin and ferritin levels in infants at three months of age. Mothers and their infants born through vaginal delivery, at term, and without congenital anomalies (325 pairs) were recruited at a hospital in São Paulo, Brazil, in 2006 (164 in the delayed clamping subgroup and 161 in the early clamping subgroup). Maternal hemoglobin at delivery, umbilical cord hemoglobin, and ferritin were recorded. At three months follow-up, venous blood samples were drawn from 224 (69%) infants for hemoglobin and ferritin measurement. Socioeconomic, maternal reproductive, anthropometric, and infant feeding variables were studied. Multiple linear regression models were used to analyze the data. The effect of delayed clamping at birth, measured at three months, was only significant for ferritin (p = 0.040), and the concentration was higher (23.29ng/mL) in this subgroup as compared to the early clamping subgroup. Delayed umbilical cord clamping can serve as a strategy to improve infant iron status and prevent iron deficiency.

    We report pertussis cases in 4 infants less than 6 months admitted with symptoms compatible with pertussis to the intensive care unit of the Università Cattolica del Sacro Cuore in Rome, April 2014. Realtime PCR confirmed pertussis diagnosis for the 4 infants, 2 of them were cousins, and for the household contacts of 1 of them. Analysis of pertussis toxin, its promoter and pertactin was also performed. First of all, this report emphasizes the need to investigate household contact of infants with pertussis; secondly, to evaluate the selective vaccination of household members of newborns as an effective program to reduce pertussis in infants.

  3. Very low birth weight infants: effects of brain growth during infancy on intelligence quotient at 3 years of age.

    1986-02-01

    To evaluate the role of postnatal growth on IQ at 3 years of age, 139 appropriate for gestational age, very low birth weight infants (less than 1.5 kg) born in 1977 and 1978 were studied at 40 weeks (term), and at 8, 20, and 33 months (corrected) of age. Weight, height, and head circumference were measured at each age, neurologic status was measured at 20 months, and Stanford Binet IQ at 33 months. Multiple regression analysis revealed that head circumference at 8 months of age is the best growth predictor of IQ at 3 years of age. Path analysis was performed to measure the effects of biologic and social factors measured earlier in life on IQ at 3 years. These factors explained 43% of the variance in IQ at 3 years of age. Head circumference at 8 months had a direct effect on IQ at 3 years, controlling for all other variables in the model. Neonatal risk had an indirect effect via head circumference. Neurologic impairment had direct and indirect (via head circumference) effects; race and socioeconomic status had direct effects on IQ but no effects on growth at 8 months of age. Thus, brain growth at 8 months significantly influenced 3 year IQ at 3 years of age among very low birth weight infants, even when medical and sociodemographic variables were controlled.

  4. Length velocity acceleration at 9 months of age in a representative birth cohort of Dutch infants.

    According to the ICP (infancy-childhood-puberty) growth model, statural growth can be divided into three partially superimposed components assumed to represent different physiologic mechanisms. This model predicts a sudden acceleration of length velocity (LV) at the onset of the childhood component around 9 months. The existence of such an infancy-childhood growth spurt has not yet been firmly corroborated by epidemiological studies. In the present study length measurements were made at the target ages of 1, 3, 6, 9, 12, 15, 18 and 24 months in a birth cohort of 2034 infants. In order to check whether length growth showed a continuous smooth pattern, different mathematical models were fitted to the individual growth curves. The models included Count and Guo functions, 5th order polynomial and combinations of 5th order polynomial with the logarithmic term of the Count function and the square root term of the Guo function. We showed that in boys and girls there is a small but systematic lack of fit of the mathematical modeling, due to a sudden acceleration of LV around 9 months. In addition there was an increase in variation of attained length at this age. Comparison of unbalanced ANOVA models with and without addition of dummy variables for the target ages confirmed that there was an acceleration around 9 months that, if corrected for, leads to a significantly improved model fit (likelihood ratio test p < 0.0001). In absolute terms of LV, the misfit at 9 months was not greater than 0.5 cm/year on average. We conclude that the results of this study support the existence of a late infancy growth spurt. In our opinion, however, the magnitude of the phenomenon does not legitimate construction and use of discontinuous growth references such as the ICP reference.

    An airborne gravimeter is one of the most important tools for gravity data collection over large areas with mGal accuracy and a spatial resolution of several kilometers. In August 2012, a flight test was carried out to determine the feasibility and to assess the accuracy of the new Chinese SGA-WZ strapdown airborne gravimeter in Greenland, in an area with good gravity coverage from earlier marine and airborne surveys. An overview of this new system SGA-WZ is given, including system design, sensor performance and data processing. The processing of the SGA-WZ includes a 160 s length finite impulse response filter, corresponding to a spatial resolution of 6 km. For the primary repeated line, a mean r.m.s. deviation of the differences was less than 1.5 mGal, with the error estimate confirmed from ground truth data. This implies that the SGA-WZ could meet standard geophysical survey requirements at the 1 mGal level. PMID:26057039

    2015-01-01

    The temperature control system is one of the most important subsystems of the strapdown airborne gravimeter. Because the quartz flexible accelerometer based on springy support technology is the core sensor in the strapdown airborne gravimeter and the magnet steel in the electromagnetic force equilibrium circuits of the quartz flexible accelerometer is greatly affected by temperature, in order to guarantee the temperature control precision and minimize the effect of temperature on the gravimeter, the SGA-WZ temperature control system adopts a three-level control method. Based on the design experience of the SGA-WZ-01, the SGA-WZ-02 temperature control system came out with a further optimized design. In 1st level temperature control, thermoelectric cooler is used to conquer temperature change caused by hot weather. The experiments show that the optimized stability of 1st level temperature control is about 0.1 °C and the max cool down capability is about 10 °C. The temperature field is analyzed in the 2nd and 3rd level temperature control using the finite element analysis software ANSYS. The 2nd and 3rd level temperature control optimization scheme is based on the foundation of heat analysis. The experimental results show that static accuracy of SGA-WZ-02 reaches 0.21 mGal/24 h, with internal accuracy being 0.743 mGal/4.8 km and external accuracy being 0.37 mGal/4.8 km compared with the result of the GT-2A, whose internal precision is superior to 1 mGal/4.8 km and all of them are better than those in SGA-WZ-01.

    Vaccination of pregnant women with a pertussis containing vaccine is a recommended strategy in some industrialized countries, to protect young infants from severe disease. One of the effects of the presence of high titers of passively acquired maternal antibodies in young infants is blunting of immune responses to infant vaccination. We present infant immune responses to a fourth pertussis containing vaccine dose at 15 months of age, as a follow-up of previously presented data. In a prospective cohort study, women were either vaccinated with an acellular pertussis vaccine (Boostrix(®)) during pregnancy (vaccine group) or received no vaccine (control group). All infants were vaccinated with Infanrix Hexa(®) according to the standard Belgian vaccination schedule (8/12/16 weeks, 15 months). We report results from blood samples collected before and 1 month after the fourth vaccine dose. Immunoglobulin G (IgG) antibodies against pertussis toxin (PT), filamentous hemagglutinin (FHA), pertactin (Prn), tetanus toxoid (TT) and diphtheria toxoid (DT) were measured using commercially available ELISA tests. Antibody levels were expressed in International Units per milliliter. Demographic characteristics were similar in the vaccine and control group. Before the fourth vaccine dose, significantly lower antibody titers were measured in the vaccine group compared to the control group for anti-Prn IgG (p=0.003) and anti-DT IgG (p=0.023), with a steep decay of antibody titers since post-primary vaccination. One month after the fourth dose, antibody titers were only significantly lower in the vaccine group for anti-PT IgG (p=0.006). For all antigens, there was a rise in antibody titer after the fourth vaccine dose. The present results indicate still a minor blunting effect 1 month after a fourth vaccine dose for anti-PT antibodies. However, a good humoral immune response on all measured antigens was elicited in both groups of children. The clinical significance of such blunting

All infants underwent cataract surgery between 1 and 7 months of age. Monocular acuity was assessed at 4.5 years of age by a traveling examiner using the Amblyopia Treatment Study HOTV protocol. Results. Age at cataract surgery was weakly associated with visual acuity (Spearman rank correlation coefficient = 0.19, P = 0.041) with median visual acuity better among the younger patients (28–48 days: 0.50 logMAR, 49–210 days: 1.10 logMAR, P = 0.046). Patients from families with private insurance had significantly better median visual acuity (0.60 vs. 1.40 logMAR, P = 0.0004). No other baseline characteristic revealed a significant bivariate relationship with visual acuity. A multiple linear regression relating visual acuity to all baseline characteristics demonstrated that only the availability of private insurance was statistically significant, accounting for 12% of the variance. Conclusions. This analysis concurs with previous studies that early surgery is important for good visual outcomes in patients with unilateral infantile cataracts. The fact that only one baseline variable (private insurance) contributed to the multivariate analysis, accounting for 12% of the variance, suggests that predicting visual outcome for these patients is complicated at best, and cannot be estimated from baseline characteristics alone.

    There is growing interest in studying oxytocin biology in the context of social functioning in human and non-human primates. Studies of human subjects are typically restricted to peripheral oxytocin assessments because opportunities to collect cerebrospinal fluid (CSF) are rare. A few studies have examined CSF oxytocin levels in captive adult primates, but none to our knowledge have been conducted under free-ranging conditions and inclusive of young infants. The main goal of the present study was to establish feasibility of quantifying CSF oxytocin levels in free-ranging adult female and infant rhesus monkeys living on the island of Cayo Santiago, Puerto Rico. CSF oxytocin levels were examined in relation to individuals’ demographic and reproductive characteristics, as well as in relation to plasma cortisol levels. CSF oxytocin concentrations ranged from 36.02 to 134.41 pg/ml in adult females (ages 7–26 years; N = 31) and 35.94 to 77.3 pg/ml in infants (ages 38–134 days; N = 17). CSF oxytocin levels were positively correlated with adult female age and negatively correlated with infant age. The former correlation was driven by reproductive status. CSF oxytocin levels were unrelated to dominance rank or plasma cortisol levels. In contrast to a previous study of plasma oxytocin concentrations in this population, CSF oxytocin levels did not differ significantly between lactating and non-lactating females. In summary, these findings: 1) provide feasibility data for examining CSF oxytocin biology in free-ranging nonhuman primates and 2) indicate that CSF oxytocin levels may be a biomarker of age-related central nervous system changes across lifespan development. Although our study did not report significant associations between CSF oxytocin levels and socially-relevant demographic variables, the relationships between CSF oxytocin levels and assessments of social functioning warrant future investigation.

    The prevalence of subtle handicapping conditions, such as learning disabilities, behavior problems, and recurrent illness, in a population of 88 high-risk infants was investigated when the children reached 9 years of age. Infants had had birthweights of less than 1500 grams or had required prolonged mechanical ventilation in the neonatal period.…

    In this study, based on total Western Australian singleton Caucasian births, women who had repeatedly given birth to small-for-gestational-age (SGA) term infants ('repeater' mothers) were compared with multiparous women who had had only one such infant ('non-repeater' mothers). Women with any preterm births were excluded. The study population comprised 678 repeater and 986 non-repeater mothers. Multiple logistic regression analysis indicated that weight loss or static weight in the third trimester of pregnancy, paternal smoking, low maternal birthweight, short maternal height and unknown family disease history were independent risk factors for repeater status compared with non-repeaters. The risk associated with paternal smoking was confined to mothers who were non-smokers themselves. There may have been a direct association between paternal smoking and recurrent fetal growth retardation or paternal smoking may have acted as a 'marker' for certain behavioural, environmental, social and economic factors which were not measured. Neonatal outcome was worse for the SGA infants of non-repeater mothers than for those of repeater mothers, although the latter were significantly more likely to weight less than 2500 grams.

    Objective Investigate relationships between early blood pressure (BP) changes, receipt of anti-hypotensive therapy, and 18 – 22 month corrected age (CA) outcomes for extremely preterm infants. Design Prospective observational study of infants 230/7 – 266/7 weeks gestational age (GA). Hourly BP values and anti-hypotensive therapy exposure in the first 24 hours were recorded. Four groups were defined: infants who did or did not receive anti-hypotensive therapy in whom BP did or did not rise at the expected rate (defined as an increase in the mean arterial BP of ≥5 mmHg/day). Random-intercept logistic modeling controlling for center clustering, GA, and illness severity was used to investigate the relationship between BP, anti-hypotensive therapies, and infant outcomes. Setting Sixteen academic centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. Main Outcome Measures Death or neurodevelopmental impairment / developmental delay (NIDD) at 18 – 22 months CA. Results Of 367 infants, 203 (55%) received an anti-hypotensive therapy, 272 (74%) survived to discharge, and 331 (90%) had a known outcome at 18 – 22 months CA. With logistic regression, there was an increased risk of death/NIDD with anti-hypotensive therapy versus no treatment (odds ratio: 1.836, 95% confidence interval: 1.092 – 3.086), but not NIDD alone (odds ratio: 1.53, 95% confidence interval: 0.708 – 3.307). Conclusion Independent of early BP changes, anti-hypotensive therapy exposure was associated with an increased risk of death/NIDD at 18 to 22 months CA when controlling for risk factors known to affect survival and neurodevelopment.

    This article presents normal EEG characteristics and their maturational pattern in premature infants of 24-30 weeks gestational age. Although the very premature infants with a normal outcome are not that numerous, their normal EEG pattern should be known, as EEG constitutes a basis for neurological prognosis. Background activity is first discontinuous but the discontinuity gradually decreases and the activity is completely continuous at 30 weeks of age, during active sleep. At the same time, interburst intervals become shorter so that the proportion of time without EEG activity decreases. Based on EEG activity and eyes movements, a rough sleep state differentiation appears as early as 25 weeks of gestational age and is complete at 30 weeks. The main EEG figures are high-voltage delta waves, whose frequency is slower and amplitude higher in younger infants. Temporal delta waves occur in sequences and are characteristic of the very premature infant; they progressively become smaller and less numerous and disappear around 27-28 weeks. In contrast, occipital delta waves remain numerous; they are of high voltage and usually bilaterally superimposed with fast rhythms. Both types of frontal delta waves that are seen in 24-27 weeks premature babies disappear with maturation. Bursts of synchronized delta waves, which are less numerous than localized delta waves, also disappear before 28 weeks of gestational age. Finally, diffuse theta bursts which are mainly recorded at 26-27 weeks, progressively focus on temporal areas with maturation. At 30 weeks, they are observed on temporal areas, mainly during slow-wave sleep.

We studied 22 infants less than 7 months old undergoing minor surgery. Halothane alone or minimal Halothane anesthesia associated with caudal epidural anesthesia were used. Life-Scan analysis, in spite of wide individual variations, allowed us to detect infraclinical hypoxia episodes, it provided informations about operative confort, depth of anesthesia and added in the post-operative period an objective criteria to clinical evaluation of pain. A wide use of such a monitoring is warranted in infants.

    Infants are more susceptible to infections caused by T cell- independent type 2 (TI-2) polysaccharide antigens of certain encapsulated bacteria. Immune responses against this type of antigen are related to the splenic marginal zone (MZ). However, only few data exist on the age-dependent developmental stages of the human spleen in early childhood and on their association with different diseases. Therefore, the present study aimed to investigate spleens of a large number of children at very young ages (12 days to 32 months), derived from autopsy cases. Immunohistochemical labeling was performed on paraffin sections of 34 spleens using a panel of monoclonal antibodies. The shape and size of the white pulp compartments were examined and correlated to the cause of death of the children. Results show that the development of the different compartments was statistically age-dependent, but no clear-cut time point for the maturity of each compartment was seen. Furthermore, the MZ was significantly more often missing when sudden infant death (SID) and/or infection were the cause of death, compared with other violent or traumatic reasons that served as controls. This association supports the concept that an immature state of the spleen and especially of the MZ might contribute to the increased susceptibility to bacterial infections in young infants.

  12. Malaria in infants aged less than six months - is it an area of unmet medical need?

    PubMed Central

    2012-01-01

    Despite the protection provided by several factors, including maternal antibodies, the burden of malaria in young infants may be higher than previously thought. Infants with congenital or neonatal malaria may have a different clinical presentation than older children, and diagnosis may be confused with other neonatal diseases due to an overlap of clinical manifestations. In addition, there is little information on the use of artemisinin-based combination therapy in young infants. There is the need for a more accurate estimate of the parasite prevalence and the incidence of clinical malaria in infants under 6 months old, as well as a better characterization of risk factors, pharmacokinetic profiles, safety and efficacy of currently available anti-malarial treatments, in order to develop evidence-based treatment guidelines for this population.

    In Chile between 1969 and 1974 the birth rate declined by 10 per cent and the infant mortality rate by 18.6 per cent. In 1974 there were proportionately fewer births at high birth order than in 1969. Such births carry significantly higher risk to the infant in both the neonatal and postneonatal period of life. Comparison of data from urban areas of high and low socioeconomic status yield similar findings. PMID:7352614

    Aim Increased end-tidal carbon monoxide (ETCOc) and cytokines in preterm infants are related to bronchopulmonary dysplasia and intraventricular haemorrhages. The aim was to study the predictive value of ETCOc and cytokine levels for long-term outcome. Methods This study comprised 105 very preterm infants (57 males, 48 females; gestational age range 25wk 5d–31wk 4d; birthweight 610–2100g) who were admitted to a neonatal intensive care unit between 1 February and 31 December 2002. ETCOc, plasma tumour necrosis factor alpha (TNF-α) and interleukins (IL) 6 and 8, and malondialdehyde (MDA, a marker of lipid peroxidation), were measured at days 1, 3, and 5 of life and related to outcome at 3 years 6 months of age (Griffiths Mental Developmental Scales). Results Of the 105 infants, 69 were eligible for follow-up (37 male; 32 female; bronchopulmonary dysplasia, n=12). ETCOc at 0 to 24 hours was higher in infants with adverse outcome (Griffiths developmental quotient <85, n=15) compared with favourable outcome (2.7 SD 0.7 vs 2.0 SD 0.5; p<0.05). MDA and cytokines did not differ between groups. Regression analysis with bootstrapping of independent variables (gestational age, birthweight, ETCOc, TNF-α, IL-6, IL-8, and bronchopulmonary dysplasia) showed that ETCOc was the only parameter that correlated with outcome. The sensitivity and negative predictive value of ETCOc for adverse outcome were 93% and 85% respectively. Interpretation Adverse neurodevelopmental outcome is associated with increased endogenous carbon monoxide. ETCOc less than 2.0ppm during the first day indicates a favourable outcome. PMID:21933176

    Background Indigenous infants (infants aged under 12 months) have the highest hospital admission and emergency department presentation risks in Australia. However, there have been no recent reports comparing hospital utilisation between Indigenous and non-Indigenous infants. Methods Our primary objective was to use a large prospective population-based linked dataset to assess the risk of all-cause hospital admission and emergency department presentation in Indigenous compared to non-Indigenous infants in Western Australia (WA). Secondary objectives were to assess the effect of socio-economic status (Index of Relative Socio-Economic Disadvantage [IRSD]) on hospital utilisation and to understand the causes of hospital utilisation. Findings There were 3,382 (5.4%) Indigenous and 59,583 (94.6%) non-Indigenous live births in WA from 1 January 2010 to 31 December 2011. Indigenous infants had a greater risk of hospital admission (adjusted odds ratio [aOR] 1.90, 95% confidence interval [95% CI] 1.77–2.04, p = <0.001) and emergency department presentation (aOR 2.15, 95% CI 1.98–2.33, p = <0.001) compared to non-Indigenous infants. Fifty nine percent (59.0%) of admissions in Indigenous children were classified as preventable compared to 31.2% of admissions in non-Indigenous infants (aOR 2.12, 95% CI 1.88–2.39). The risk of hospital admission in the most disadvantaged (IRSD 1) infants in the total cohort (35.7%) was similar to the risk in the least disadvantaged (IRSD 5) infants (30.6%) (aOR 1.04, 95% CI 0.96–1.13, p = 0.356). Interpretation WA Indigenous infants have much higher hospital utilisation than non Indigenous infants. WA health services should prioritise Indigenous infants regardless of their socio economic status or where they live. PMID:27120331

    Objectives It remains unclear why substantial variations in neurodevelopmental outcomes exist within small-for-gestational-age (SGA) children. We prospectively compared 5-y neurodevelopmental outcomes across SGA etiological subgroups. Methods Children born SGA (N = 1050) from U.S. Early Childhood Longitudinal Study-Birth Cohort (2001–2007) was divided into etiological subgroups by each of 7 well-established prenatal risk factors. We fit linear regression models to compare 5-y reading, math, gross motor and fine motor scores across SGA subgroups, adjusting for socio-demographic confounders. Results Compared to singleton SGA subgroup, multiple-birth SGA subgroup had lower mean reading (adjusted mean difference, -4.08 [95% confidence interval, -6.10, -2.06]) and math (-2.22 [-3.61, -0.84]) scores. These disadvantages in reading and math existed only among multiple-birth SGA subgroup without ovulation stimulation (reading, -4.50 [-6.64, -2.36]; math, -2.91 [-4.37, -1.44]), but not among those with ovulation stimulation (reading, -2.33 [-6.24, 1.57]; math 0.63 [-1.86, 3.12]). Compared to singleton SGA subgroup without maternal smoking and inadequate gestational weight gain, singleton SGA subgroup with co-occurrence of maternal smoking and inadequate gestational weight gain (GWG) had lower mean reading (-4.81 [-8.50, -1.12]) and math (-2.95 [-5.51, -0.38]) scores. These differences were not mediated by Apgar score. Conclusions Multiple-birth SGA subgroups (vs. singleton SGA) or singleton SGA subgroup with co-occurrence of smoking and inadequate GWG (vs. singleton SGA subgroup without maternal smoking and inadequate gestational weight gain) have poorer cognitive development up to 5 y.

    Although ghrelin in cord blood has been associated to birth weight, its role in fetal and postnatal growth has not been elucidated. The aim of this study was to analyze total ghrelin, acyl ghrelin (AG), and des-acyl ghrelin (DAG) in cord blood of newborns with idiopathic birth weight alterations, and to evaluate protein expression of placental GHS-R1, in order to investigate their correlation with birth weight and placental weight. We performed a cross-sectional comparative study in umbilical cord blood and placentas from healthy mothers of SGA, AGA, and LGA (small, adequate and large for gestational age) term newborns (n = 20 per group). Cord blood total ghrelin, AG, and DAG were measured by ELISA, and placental GHS-R1 expression was evaluated by Western blot. Cord blood DAG was higher in SGA compared to AGA newborns (902.1 ± 109.1 and 597.4 ± 58.2 pg/ml, respectively, p = 0.01) while LGA and AGA showed similar values (627.2 ± 76.4 pg/ml for LGA, p = 0.80). DAG negatively correlated with birthweight (r = -0.31, p = 0.02) and placental weight (r = -0.33, p = 0.02). No differences in AG or total ghrelin were found. GHS-R1 protein in placenta was not differentially expressed among SGA, AGA, and LGA. Our results suggest a role of DAG in intrauterine growth. Further studies are needed in order to elucidate the mechanisms by which DAG participates in fetal growth.

  18. Utility of clinical parameters to identify HIV infection in infants below ten weeks of age in South Africa: a prospective cohort study

    2011-01-01

    Background As HIV-infected infants have high mortality, the World Health Organization now recommends initiating antiretroviral therapy as early as possible in the first year of life. However, in many settings, laboratory diagnosis of HIV in infants is not readily available. We aimed to develop a clinical algorithm for HIV presumptive diagnosis in infants < 10 weeks old using screening data from the Children with HIV Early Antiretroviral therapy (CHER) study in South Africa. HIV-infected and HIV-uninfected exposed infants < 10 weeks of age were identified through Vertical Transmission Prevention programs. Clinical and laboratory data were systematically recorded, groups were compared using Kruskal-Wallis, analysis of variance (ANOVA), and Fisher's exact tests. Receiver Operating Characteristic (ROC) curves were compiled using combinations of clinical findings. Results 417 HIV-infected and 125 HIV-exposed, uninfected infants, median age 46 days (IQR 38-55), were included. The median CD4 percentage in HIV-infected infants was 34 (IQR 28-41)%. HIV-infected infants had lower weight-for-age, more lymphadenopathy, oral thrush, and hepatomegaly than exposed uninfected infants (Adjusted Odds Ratio 0.51, 8.8, 5.6 and 23.5 respectively; p < 0.001 for all). Sensitivity of individual signs was low (< 20%) but specificity high (98-100%). If any one of oral thrush, hepatomegaly, splenomegaly, lymphadenopathy, diaper dermatitis, weight < 50th centile are present, sensitivity for HIV infection amongst HIV-exposed infants was 86%. These algorithms performed similarly when used to predict severe immune suppression. Conclusions A combination of physical findings is helpful in identifying infants most likely to be HIV-infected. This may inform management algorithms and provide guidance for focused laboratory testing in some settings, and should be further validated in these settings and elsewhere. PMID:22103994

    Purpose A large body of literature has indicated vowel space area expansion in infant-directed (ID) speech compared with adult-directed (AD) speech, which may promote language acquisition. The current study tested whether this expansion occurs in storybook speech read to infants at various points during their first 2 years of life. Method In 2 studies, mothers read a storybook containing target vowels in ID and AD speech conditions. Study 1 was longitudinal, with 11 mothers recorded when their infants were 3, 6, and 9 months old. Study 2 was cross-sectional, with 48 mothers recorded when their infants were 3, 9, 13, or 20 months old (n = 12 per group). The 1st and 2nd formants of vowels /i/, /ɑ/, and /u/ were measured, and vowel space area and dispersion were calculated. Results Across both studies, 1st and/or 2nd formant frequencies shifted systematically for /i/ and /u/ vowels in ID compared with AD speech. No difference in vowel space area or dispersion was found. Conclusions The results suggest that a variety of communication and situational factors may affect phonetic modifications in ID speech, but that vowel space characteristics in speech to infants stay consistent across the first 2 years of life.

    2013-01-01

    Background Identifying unwell neonates, particularly in the first week of life, is often subjective. If normal values are known, calculating the weight lost or gained from birth weight can be a useful adjunct in the evaluation of the health of a neonate. Methods Serial body weights of well, term, breast fed infants who were attending for routine follow up, were recorded at the Shoklo Malaria Research Unit clinic in Maela Camp for displaced persons on the Thailand Myanmar border. Newborn examination was routine. Weight loss, expressed as percent weight lost from birth weight, and weight gain, expressed as a velocity (g/kg/day), was calculated for the first seven days of life. The results from normal birth weight infants, low birth weight infants (<2.5 kg) and small for gestational age infants (SGA) were examined. Results In the first week of life there were no significant differences in weight gained or lost across the three study groups. The maximum weight lost was 4.4% (95% CI 4.1 – 4.6%), which occurred on day three. Weight gain ranged from 13 g/kg/day [95% CI 10 – 16] on day four to 18 g/kg/day [95% CI 15 – 20] on days six and seven. Conclusions Use of these normal values for weight gain and loss, allows infants falling outside of the expected range (95% CI) to be easily identified and subsequently highlighted as needing further medical review.

    The current study examined the effects of a natural disaster (a sudden onset flood) as a stressor in pregnancy on infant fine and gross motor development at 2, 6, and 16 months of age. Whether the timing of the stressor in pregnancy or sex of the infant moderated the impact of the prenatal maternal stress on motor development was also explored. Mothers' objective experiences of the flood, emotional reactions and distress, and their cognitive appraisal of the event were assessed retrospectively. Infants' fine and gross motor skills were assessed with the Ages and Stages Questionnaire, and results showed age-related changes in the effects of prenatal maternal stress on these domains. At 2 months, higher levels of prenatal maternal stress was positively related to infant motor development, yet at 6 and 16 months of age there was a negative association, particularly if flood exposure occurred later in pregnancy and if mothers had negative cognitive appraisals of the event. Results also showed differential effects of the maternal stress responses to the floods on infants' fine and gross motor development at each age and that infant sex did not buffer these effects. © 2016 Wiley Periodicals, Inc.

    A double-blind, randomized clinical trial was conducted to determine the effects of prevention of zinc deficiency on cognitive and sensorimotor development during infancy. At 6 mo of age, infants were randomly assigned to be administered a daily liquid supplement containing 10 mg/d of zinc (zinc sulfate), 10 mg/d of iron (ferrous sulfate), and 0.5 mg/d of copper (copper oxide), or an identical daily liquid supplement containing only 10 mg/d of iron and 0.5 mg/d of copper. Various controls were implemented to ensure adherence to the supplement protocol. A battery of developmental assessments was administered from 6 to 18 mo of age that included a visual habituation/recognition memory task augmented with heart rate at 6, 9, and 12 mo of age; the Bayley Scales of Infant Development, 2nd edition (BSID2) at 6, 12, and 18 mo; the A-not-B error task at 9 and 12 mo; and free-play attention tasks at 12 and 18 mo. Only infants supplemented with zinc had the normative decline in look duration from 6 to 12 mo during habituation and a normative decline in shifting between objects on free-play multiple-object attention tasks from 12 to 18 mo of age. The 2 groups did not differ on any of the psychophysiologic indices, the BSID2, or the A-not-B error task. The findings are consistent with zinc supplementation supporting a profile of normative information processing and active attentional profiles during the first 2 y of life. This trial was registered at clinicaltrials.gov as NCT00589264. PMID:24850625

    Individuals born small for gestational age (SGA) are supposed to be at higher risk to develop cardiovascular disorders, and recent report showed that concurrent obesity influences blood pressure (BP) in SGA children. Our aim was to investigate the impact of obesity and birth weight on blood pressure values in young adult men born SGA and controls born after normal pregnancy, Normotensive, non-treated adult men were enrolled (N = 185; mean age 21.29 +/- 0.9 years). Birth parameters were obtained from medical records and SGA was defined as birth weight (BW) under 10th percentile for gestational age and obesity as BMI > 25 kg/m2. According to the presence or absence of obesity and BW the subjects were divided into four groups: (1) non-obese with normal BW (N = 50), (2) non-obese SGA (N = 67), (3) obese with normal BW (N = 40), (4) obese SGA (N = 28). BP was measured using Omron M6 and Spacelab 90207 device following the ESH/ESC guidelines. Systolic BP, 24-hour BP variability and pulse pressure were significantly higher in SGA subjects than in those with normal BW (p < 0.05). The highest 24-hour and daytime systolic BP values as well as 24-hour pulse pressure were found in the subgroup of obese SGA subjects (p < 0.001). Significant differences for the above parameters were observed between obese SGA group and non-obese SGA group (p < 0.05). Obese SGA subjects had higher 24-hour and daytime systolic BP values compared to obese normal BW group. No difference was found in BP between non-obese SGA and non-obese group with normal BW (p > 0.05). In addition to BW and shorter pregnancy duration, obesity concurrently and significantly determines systolic BP in young normotensive men and point to a need for more aggressive implementation of healthy lifestyle as early as possible.

    To evaluate the epidemiological significance of HEp-2 cell-adherent Escherichia coli isolates in diarrheal disease, we performed a study with 513 Venezuelan infants with diarrhea and 241 age-matched controls to determine the prevalence of enteropathogenic E. coli (enteroadherent E. coli, enterotoxigenic E. coli, enteroinvasive E. coli, and enterohemorrhagic E. coli) and their correlation with O:H serotypes. E. coli isolates exhibiting localized and aggregative adherence in the HEp-2 cell assay were significantly more frequently isolated from the patients (8.5 and 26.9%, respectively) than from the controls (1.7 and 15%, respectively). This difference was significant for the group 0 to 2 months of age but for older infants. Regardless of age, E. coli isolates with diffuse adherence were found at similar frequencies in both the patients and the controls. A striking correlation between classic O serogroups and localized adherence was also observed. These findings confirm the pathogenic role of E. coli with localized and aggregative adherence in diarrheal disease, as well as the epidemiological importance of O:H serotyping for characterizing localized-adhering E. coli.

    Aims To determine whether DTPP+Hib vaccination (diphtheria, tetanus, pertussis, poliomyelitis +/− haemophilus) increased the risk of sudden unexpected death (SUD) in children under 3 months of age. Methods We conducted a multicentre case-control study in the 28 French ‘SIDS Centers’. Case selection was based on death labelled sudden infant death syndrome (SIDS) of an infant aged between 30 and 90 days. Three living controls were selected, matched for sex, gestational age and born immediately after the victim in the same maternity unit. Results We identified 114 cases of SUD aged between 30 and 90 days and 341 live controls matched for age and sex and born in the same maternity unit as the case. DTPP±Hib immunization did not increase the risk of SUD (OR 1.08) (95% CI 0.49, 2.36) in children under 3 months of age when adjusted for sleeping position, illness in the week before death, maternal tobacco consumption, birth weight, type of mattress, breastfeeding and sex. However, low birth-weight (6.53 [2.29, 18.9]), multiple birth (5.1 [1.76, 15.13]), no breastfeeding (1.77 [1.1, 2.85]), prone sleeping position (9.8 [5, 8, 18, 9]), soft mattress (3.26 [1.69, 6.29]), recent illness (3.44 [1.84, 6.41]) and parental smoking (1.74 [1.2, 2.96]) were confirmed as risk factors in early SIDS. Conclusions DTPP±Hib immunization is not a risk factor for early SUD. In this population, we found the same risk factors as described for SIDS. PMID:11298074

    Tryptophan can be metabolized via 5-hydroxytryptamine=serotonin to melatonin by a series of 4 enzymes in pineal body. Lack of serotonin in body fluid in the brain during daytime can lead to several psychiatric disorders, while shortage of plasma-melatonin at night can be related to sleep disorders. The Morning-Evening (M-E) questionnaire and the original questionnaire including questions on sleep habits, mental symptoms, and contents of meals were administered to 1055 infants aged 0-6 yrs, 751 students attending an elementary school, and 473 students attending junior high school in Kochi City (33 degrees N). The index of tryptophan taken at breakfast (Trp-Index) was calculated as tryptophan amount per one meal based on the tryptophan included in each 100 g of the foods and a standard amount of food per one meal. A significant positive-correlation between M-E scores and Trp-Index was not shown by relatively older students, aged 9-15 yrs (Pearson's test, r=0.044-0.123, p=0.071-0.505), whereas a significant positive correlation was shown by infants and young elementary school students aged 0-8 yrs (r=0.180, 0.258, p<0.001). The more frequently the infants had difficulty falling asleep at bedtime and waking up in the morning, the less the Trp-Indices taken at breakfast were (Kruskall-Wallis-test, p=0.027 for difficulty falling asleep; p=0.008 for difficulty waking up). The more frequently infants became angry even by a little trigger, or depressed, the lower (more evening-typed) the M-E scores were (Kruskal-Wallis test: p

    The aim of this study was to evaluate the effectiveness of oral sucrose in decreasing pain during minor procedures in infants of 1-6 months corrected age. A blinded randomized controlled trial with infants aged 4-26 weeks who underwent venipuncture, heel lance or intravenous cannulation were stratified by corrected age into > 4-12 weeks and > 12-26 weeks. They received 2 mL of either 25% sucrose or sterile water orally 2 minutes before the painful procedure. Nonnutritional sucking and parental comfort, provided in adherence to hospital guidelines, were recorded. Pain behavior was recorded using a validated 10 point scale at baseline, during and following the procedure. Data collectors were blinded to the intervention. A total of 21 and 20 infants received sucrose and water, respectively, in the > 4-12-week age group, and 21 and 22, respectively, in the > 12-26-week age group. No statistical differences were found in pain scores between treatment and control groups at any data collection points in either age group. Infants aged > 4-12 weeks who did nonnutritional sucking showed statistically significantly lower median pain scores at 1, 2, and 3 minutes after the procedure than those who did not suck. Infants aged > 4-26 weeks exhibited pain behavior scores that indicated moderate to large pain during painful procedures; however, there was insufficient evidence to show that 2 mL 25% sucrose had a statistically significant effect in decreasing pain. Infants should be offered nonnutritional sucking in compliance with the Baby Friendly Health Initiative during painful procedures.

    Epidemiologic research on the effects of parental occupational exposures on fetal development has been limited. The National Natality and Fetal Mortality surveys obtained applicable data of probability samples of live births and fetal deaths which occurred in the US in 1980 among married women. Analyses were conducted for case groups of stillbirths (2,096 mothers, 3,170 fathers), preterm deliveries (<37 weeks completed gestation) (363 mothers, 552 fathers), and small-for gestational-age infants (218 mothers, 371 fathers) compared with controls. Occupational exposures were defined by industry of employment and by imputed exposures based on a job-exposure linkage system. For stillbirth, maternal work in the rubber, plastics, and synthetics industry and lead exposure and paternal employment in the textile industry had the largest odds ratios. Preterm birth was most strongly associated with maternal lead exposure, corroborating previous findings. Twofold increased risk of preterm delivery was found with paternal employment in the glass, clay, and stone; textile; and mining industries. Paternal exposures to x-rays and polyvinyl alcohol were associated with 1.5-fold increase in risk. The occupation of the mother was not associated with delivery of a small-for-gestational-age infant, in contrast to paternal employment in the art and textile industries. Several toxic agents were associated with risk elevation of 1.3 or greater for fathers, most notably benzene.

  14. Specific Infant Feeding Practices Do Not Consistently Explain Variation in Anthropometry at Age 1 Year in Urban United States, Mexico, and China Cohorts12

    Infant feeding practices generally influence infant growth, but it is unclear how introduction of specific foods affects growth across global populations. We studied 3 urban populations in the Global Exploration of Human Milk study to determine the association between infant feeding and anthropometry at 1 y of age. Three hundred sixty-five breastfeeding mother-infant pairs (120 US, 120 China, and 125 Mexico) were recruited soon after the infant’s birth. Enrollment required agreement to breastfeed ≥75% for at least 3 mo. Weekly, 24-h, food frequency data were conducted on infants for 1 y and exclusive breastfeeding (EBF) duration and timing of specific complementary food introduction were calculated. Weight and length were measured at age 1 y and anthropometry Z-scores calculated using WHO standards. Cohorts in the 3 urban populations (Shanghai, China; Cincinnati, USA; and Mexico City, Mexico) differed by median EBF duration (5, 14, and 7 wk, respectively; P < 0.001), timing of introduction of meat/eggs/legumes (4.8, 9.3, and 7.0 mo, respectively; P < 0.0001), and other feeding practices. By age 1 y, infants in Shanghai were heavier and longer than Cincinnati and Mexico City infants (P < 0.001). Adjusting for nonfeeding covariates, the only feeding variable associated with anthropometry was EBF duration, which was modestly inversely associated with weight-for-age but not length-for-age or BMI Z-scores at 1 y. Although feeding variables differed by cohort, their impact on anthropometry differences was not consistent among cohorts. Overall, across these urban, international, breast-fed cohorts, differences in specific feeding practices did not explain the significant variation in anthropometry. PMID:23236024

    During the second year of the "Iron-like Turkey" Project, in which all children aged 4-6 months in Turkey receive iron supplementation for 5 months, we aimed to assess the utilization of iron supplementation in the field, as well as the prevalence of anemia in healthy infants aged 12-23 months, while determining a variety of sociodemographic and nutritional factors for anemia in three of the 12 NUTS (Nomenclature of Territorial Units for Statistics) regions (regions with the highest, lowest and middle under-5 malnutrition levels). In a community-based, cross-sectional survey using a multi-staged, weighted, cluster-selected sample, children aged 12-23 months with birthweight ≥2500 g, no chronic illness, no history of blood disease, and from term and singleton pregnancy were enrolled; 1589 children met the criteria. The mean±SD age of children surveyed was 17.8±3.6 months. Of the parents, 72.4% claimed that their physician had recommended iron supplementation, and 68.8% had given supplementation to their children. Overall prevalence of anemia was 7.3%. Multivariate analysis revealed that the frequency of anemia decreased significantly in older infants, when supplementation was recommended by health providers, when an infant was breastfed longer than 6 months, and when the mother received iron supplementation during pregnancy. However, anemia prevalence increased when the infant received iron supplementation at a later age (³9 months), lived in a crowded family (³6 persons), and when the mother had a history of iron deficiency anemia. Anemic infants had significantly lower z scores of weight for age than non-anemic ones. This survey suggests that iron supplementation during pregnancy, initiation of iron supplementation in infants at 4-6 months of age, effective counseling on supplementation, subsequent compliance, support of breastfeeding, and effective training of health care personnel are effective strategies for prevention of anemia in the community.

    Background. Mother's milk is the best for the babies. Protective and preventive role of breast milk was evaluated in this study by assessing the relation of type of feeding and duration of hospital stay or morbidity. Methods. This prospective study was conducted in a tertiary care hospital and 232 infants in the age group of 14 weeks to 6 months formed the sample. There are two groups of infants, that is, one for breastfed and one for top fed infants. Statistical analysis was done and results were calculated up to 95% to 99% level of significance to find effect of feeding pattern on hospital stay due to various diseases and morbidity. Results. Prolonged hospital stay, that is, >7 days, was lesser in breastfed infants and results were statistically significant in case of gastroenteritis (p value < 0.001), bronchopneumonia (p value = 0.0012), bronchiolitis (p value = 0.005), otitis media (p value = 0.003), and skin diseases (p value = 0.047). Lesser morbidity was seen in breastfed infants with gastroenteritis (p value 0.0414), bronchopneumonia (p value 0.03705), bronchiolitis (p value 0.036706), meningitis (p value 0.043), and septicemia (p value 0.04). Conclusions. Breastfed infants have shorter hospital stay and lesser morbidity in regard to various diseases as compared to top fed infants.

    This study was conducted to explore and identify factors associated with the practice of early introduction of solid, semi-solid or soft foods among infants aged 3-5 months in four Anglophone West African countries. Data sources for the analyses were the latest Demographic and Health Survey datasets of the 4 countries, namely Ghana (GDHS, 2008), Liberia (LDHS, 2007), Nigeria (NDHS, 2013) and Sierra Leone (SLDHS, 2008). Multiple logistic regression methods were used to analyze the factors associated with early introduction of solid, semi-solid or soft foods among infants aged 3-5 months, using individual-, household- and community-level determinants. The sample consisted of 2447 infants aged 3-5 months from four Anglophone West African countries: 166 in Ghana, 263 in Liberia, 1658 in Nigeria and 360 in Sierra Leone. Multivariable analyses revealed the individual factors associated with early introduction of solid, semi-solid or soft foods in these countries. These included increased infant's age, diarrhea, acute respiratory infection and newborns perceived to be small by their mothers. Other predictors of early introduction of solid, semi-solid or soft foods were: mothers with no schooling, young mothers and fathers who worked in an agricultural industry. Public health interventions to improve exclusive breastfeeding practices by discouraging early introduction of solid, semi-solid or soft foods are needed in all 4 countries, targeting especially mothers at risk of introducing solid foods to their infants early.

    Objectives To compare the food, nutrient and ‘family meal’ intakes of infants following baby-led weaning (BLW) with those of infants following a more traditional spoon-feeding (TSF) approach to complementary feeding. Study design and participants Cross-sectional study of dietary intake and feeding behaviours in 51 age-matched and sex-matched infants (n=25 BLW, 26 TSF) 6–8 months of age. Methods Parents completed a questionnaire, and weighed diet records (WDRs) on 1–3 non-consecutive days, to investigate food and nutrient intakes, the extent to which infants were self-fed or parent-fed, and infant involvement in ‘family meals’. Results BLW infants were more likely than TSF infants to have fed themselves all or most of their food when starting complementary feeding (67% vs 8%, p<0.001). Although there was no statistically significant difference in the large number of infants consuming foods thought to pose a choking risk during the WDR (78% vs 58%, p=0.172), the CI was wide, so we cannot rule out increased odds with BLW (OR, 95% CI: 2.57, 0.63 to 10.44). No difference was observed in energy intake, but BLW infants appeared to consume more total (48% vs 42% energy, p<0.001) and saturated (22% vs 18% energy, p<0.001) fat, and less iron (1.6 vs 3.6 mg, p<0.001), zinc (3.0 vs 3.7 mg, p=0.001) and vitamin B12 (0.2 vs 0.5 μg, p<0.001) than TSF infants. BLW infants were more likely to eat with their family at lunch and at the evening meal (both p≤0.020). Conclusions Infants following BLW had similar energy intakes to those following TSF and were eating family meals more regularly, but appeared to have higher intakes of fat and saturated fat, and lower intakes of iron, zinc and vitamin B12. A high proportion of both groups were offered foods thought to pose a choking risk. PMID:27154478

    The present study examined the development of parent use of food to soothe infant distress by examining this feeding practice longitudinally when infants were 6, 12 and 18 months of age. Two measures of feeding to soothe were obtained: parent self-report and observations of food to soothe during each laboratory visit. Demographic and maternal predictors of food to soothe were examined as well as the outcome, infant weight gain. The findings showed that the two measures of food to soothe were unrelated but did reveal similar and unique relations with predictor variables such as parent feeding style and maternal self-efficacy. Only observations of the use of food to soothe were related to infant weight gain. The findings indicate that the two measures of food to soothe may be complementary and that observations of this feeding practice may capture certain relations that are not obtained through the use of self-report.

    Being born small for gestational age (SGA) is a putative risk factor for the development of later cognitive and psychiatric health problems. While the inter-uterine environment has been shown to play an important role in predicting birth weight, little is known about the genetic factors that might be important. Here we test the hypothesis that neurotransmitter-regulating genes implicated in psychiatric disorders previously shown to be associated with SGA (such as attention-deficit hyperactivity disorder) are themselves predictive of SGA. DNA was collected from 227 SGA and 319 appropriate for gestational age children taking part in the Auckland Birthweight Collaborative Study. Candidate single nucleotide polymorphisms in genes regulating activity within dopamine, serotonin, glutamate and gamma-aminobutyric acid pathways were genotyped. Multiple regression analysis, controlling for potentially confounding factors, supported nominally significant associations between SGA and single nucleotide polymorphisms in COMT, HTR2A, SLC1A1 and SLC6A1. This is the first evidence that genes implicated in psychiatric disorders previously linked to SGA status themselves predict SGA. This highlights the possibility that the link between SGA and psychiatric disorders such as attention-deficit hyperactivity disorder may in part be genetically determined - that SGA marks pre-existing genetic risk for later problems.

    Being born small for gestational age (SGA) is a putative risk factor for the development of later cognitive and psychiatric health problems. While the inter-uterine environment has been shown to play an important role in predicting birth weight, little is known about the genetic factors that might be important. Here we test the hypothesis that neurotransmitter-regulating genes implicated in psychiatric disorders previously shown to be associated with SGA (such as attention-deficit hyperactivity disorder) are themselves predictive of SGA. DNA was collected from 227 SGA and 319 appropriate for gestational age children taking part in the Auckland Birthweight Collaborative Study. Candidate single nucleotide polymorphisms in genes regulating activity within dopamine, serotonin, glutamate and gamma-aminobutyric acid pathways were genotyped. Multiple regression analysis, controlling for potentially confounding factors, supported nominally significant associations between SGA and single nucleotide polymorphisms in COMT, HTR2A, SLC1A1 and SLC6A1. This is the first evidence that genes implicated in psychiatric disorders previously linked to SGA status themselves predict SGA. This highlights the possibility that the link between SGA and psychiatric disorders such as attention-deficit hyperactivity disorder may in part be genetically determined - that SGA marks pre-existing genetic risk for later problems.

    Infant temperament and parental feeding practices may be risk factors for childhood obesity, however most studies have relied upon parent-report assessments. We tested whether infant emotional distress and maternal restrictive feeding at 12-months of age, assessed observationally at a home feeding interaction, predicted child BMI through age 6years. We conducted a prospective observational study of 86 children (34 girls and 52 boys, from 55 adoptive and 31 non-adoptive families) enrolled in the Colorado Adoption Project. Mother-infant feeding interactions were video-recorded during a home snack or meal at year 1, and child anthropometrics (length or height, and weight) were assessed at years 1 through 6. The main outcome measures were child weight-for-length at year 1 and body mass index (BMI: kg/m(2)) at years 2-6. Results of generalized linear models indicated that greater infant emotional distress at 12-months predicted greater increases in child weight status through age 6years, B=0.62 and odds ratio (OR)=1.87. In separate analyses, restrictive feeding interacted with child sex in predicting weight status trajectories (p=.012). Male infants whose mothers displayed any compared to no restriction at year 1 showed a downward BMI trajectory from 2 to 6years; for female infants, exposure to any compared to no restriction prompts predicted increasing BMI from 4 to 6years. In sum, early obesity prevention strategies should pay greater attention to infant temperament, especially distress and negative affect, and how parents respond to such cues. Additionally, 'responsive feeding' strategies that provide an alternative to restriction warrant greater research during infancy. PMID:26872074

  9. Preterm birth and behaviour problems in infants and preschool-age children: a review of the recent literature.

    The behaviour problems of children born preterm at school age are well known, but there have been few studies on the behaviour problems of preterm-born infants during infancy and at preschool age. Fourteen cohort studies published in PubMed and PsycINFO between 2000 and 2012 were reviewed with a focus on the type, occurrence, comorbidity, stability, prediction, perinatal, social, and relational risk factors for behaviour problems of preterm-born children in infancy (0-2y) and at preschool age (3-5y). The relational risk factor was considered in an additional four papers. Very-preterm, very-low-birthweight, and moderately-preterm children, in both age groups, show more behaviour problems than term-born comparison children even after perinatal and social risk factors and cognitive performance have been controlled for. Poor social/interactive skills, poor behavioural and emotional self-regulation, emotional difficulties, and reduced attention are the most common behaviour problems. Behaviour problems in infancy are predictive of later behaviour problems and they should be included in follow-up programmes.

  10. Efficacy of baby-CIMT: study protocol for a randomised controlled trial on infants below age 12 months, with clinical signs of unilateral CP

    PubMed Central

    2014-01-01

    Background Infants with unilateral brain lesions are at high risk of developing unilateral cerebral palsy (CP). Given the great plasticity of the young brain, possible interventions for infants at risk of unilateral CP deserve exploration. Constraint-induced movement therapy (CIMT) is known to be effective for older children with unilateral CP but is not systematically used for infants. The development of CIMT for infants (baby-CIMT) is described here, as is the methodology of an RCT comparing the effects on manual ability development of baby-CIMT versus baby-massage. The main hypothesis is that infants receiving baby-CIMT will develop manual ability in the involved hand faster than will infants receiving baby-massage in the first year of life. Method and design The study will be a randomised, controlled, prospective parallel-group trial. Invited infants will be to be randomised to either the baby-CIMT or the baby-massage group if they: 1) are at risk of developing unilateral CP due to a known neonatal event affecting the brain or 2) have been referred to Astrid Lindgren Children’s Hospital due to asymmetric hand function. The inclusion criteria are age 3–8 months and established asymmetric hand use. Infants in both groups will receive two 6-weeks training periods separated by a 6-week pause, for 12 weeks in total of treatment. The primary outcome measure will be the new Hand Assessment for Infants (HAI) for evaluating manual ability. In addition, the Parenting Sense of Competence scale and Alberta Infant Motor Scale will be used. Clinical neuroimaging will be utilized to characterise the brain lesion type. To compare outcomes between treatment groups generalised linear models will be used. Discussion The model of early intensive intervention for hand function, baby-CIMT evaluated by the Hand Assessment for Infants (HAI) will have the potential to significantly increase our understanding of how early intervention of upper limb function in infants at risk of

    Fetal growth restriction is found both in babies who are preterm or full-term, and in either case has important adverse effects on subsequent survival, health, growth and development. Fetal growth restriction is usually assessed by comparing the weight of the newborn with the expected weight for the child's gestational age using less than the 10th centile of a reference population for fetal growth as the threshold for being called small for gestational age (SGA). We estimate that in 2010 32.4 million babies were born SGA in low- and middle-income countries, constituting 27% of all live births. The estimated prevalence of SGA is highest in South Asia and in Sahelian countries of Africa. India has the world's largest number of SGA births, 12.8 million in 2010, due to the large number of births and the high proportion, 46.9%, of births that are SGA. The prevalence of SGA births is approximately double the prevalence of low-birthweight births (using the common indicator of <2,500 g birthweight) globally and in the world's regions. Thus, given the adverse effects of being born SGA, even weighing 2,500 g or more, it is important that maternal, neonatal and child health programs seek and use information on gestational age as well as birthweight to appropriately assess the newborn's risks and direct care.

    The current research investigates infants' perception of a novel object from a category that is familiar to young infants: key rings. We ask whether experiences obtained outside the lab would allow young infants to parse the visible portions of a partly occluded key ring display into one single unit, presumably as a result of having categorized it…

  14. Asymmetrical motor behaviour as a window to early leg preference: a longitudinal study in infants 7-12 months of age.

    2016-01-01

    This longitudinal study explored leg preference in infancy during half-kneel pulling-to-stand (PTS) and asymmetrical four-point kneeling, which is part of the typical motor repertoire of infants. The special characteristics of the half-kneel PTS as a discrete task, performed in a bilateral context provide the opportunity to explore leg preference during an asymmetrical behaviour. Twenty-seven infants were observed in their homes, every 3 weeks between the ages of 7-12 months. Leg preference was determined by the "lead-out" limb used as the infants pulled to stand from the half-kneeling position (half-kneel PTS). As a complementary measure, the leading leg during asymmetrical four-point kneeling and crawling ("asymmetrical four-point patterns") was used in the 10 infants who developed these patterns. The infants studied showed a general preference for using a leading leg during half-kneel PTS, which was mostly consistent over the study period. A strong correlation was found between leg preferences during half-kneel PTS and asymmetrical four-point patterns. The findings documented functional asymmetry in infant lower limbs during half-kneel PTS and asymmetrical four-point patterns, highlighting the importance of the tasks used to define leg preference.

  15. When infants talk, infants listen: pre-babbling infants prefer listening to speech with infant vocal properties.

    To learn to produce speech, infants must effectively monitor and assess their own speech output. Yet very little is known about how infants perceive speech produced by an infant, which has higher voice pitch and formant frequencies compared to adult or child speech. Here, we tested whether pre-babbling infants (at 4-6 months) prefer listening to vowel sounds with infant vocal properties over vowel sounds with adult vocal properties. A listening preference favoring infant vowels may derive from their higher voice pitch, which has been shown to attract infant attention in infant-directed speech (IDS). In addition, infants' nascent articulatory abilities may induce a bias favoring infant speech given that 4- to 6-month-olds are beginning to produce vowel sounds. We created infant and adult /i/ ('ee') vowels using a production-based synthesizer that simulates the act of speaking in talkers at different ages and then tested infants across four experiments using a sequential preferential listening task. The findings provide the first evidence that infants preferentially attend to vowel sounds with infant voice pitch and/or formants over vowel sounds with no infant-like vocal properties, supporting the view that infants' production abilities influence how they process infant speech. The findings with respect to voice pitch also reveal parallels between IDS and infant speech, raising new questions about the role of this speech register in infant development. Research exploring the underpinnings and impact of this perceptual bias can expand our understanding of infant language development.

    BACKGROUND: Approximately 8% of the world population resides above 1,600 m, with about 10 million people living above 2,500 m in Colombia. However, reference values for polysomnography (PSG) and oxygen saturation (Spo2) of children < 2 years old residing at high altitude are currently unavailable. METHODS: Healthy infants aged 1 to 18 months born and residing at high altitude (Bogotá: 2,640 m) underwent overnight PSG. Four age groups were defined: group 1, < 45 days; group 2, 3 to 4 months; group 3, 6 to 7 months; and group 4, 10 to 18 months. Of 122 children enrolled, 50 had three consecutive PSG tests and were analyzed as a longitudinal subcohort. RESULTS: A total of 281 PSG tests were performed in 122 infants (56% girls): group 1, 106 PSG tests; group 2, 89 PSG tests; group 3, 61 PSG tests; and group 4, 25 PSG tests. Active sleep diminished and quiet sleep increased with maturation. Apnea-hypopnea indexes (total, central, and obstructive) were highest in group 1 (21.4, 12.4, and 6.8/h total sleep time, respectively) and diminished with age (P < .001). Mean Spo2 during waking and sleep increased with age (P < .001). Nadir Spo2 values during respiratory events were lower in younger infants. Longitudinal assessments of 50 infants confirmed the temporal trends described for the cross-sectional dataset. CONCLUSIONS: Healthy infants (≤ 18 months old) born and residing at high altitude show preserved sleep architecture but higher apnea-hypopnea indexes and more prominent desaturation with respiratory events than do those living at low altitude. The current study findings can be used as reference values for infants at high altitude. PMID:25811138

    Previously we identified associations between the mother's air pollution exposure and birth weight for births in Connecticut and Massachusetts from 1999-2002. Other studies also found effects, though results are inconsistent. We explored potential uncertainties in earlier work and further explored associations between air pollution and birth weight for PM10, PM2.5, CO, NO2, and SO2. Specifically we investigated: (1) whether infants of younger (<=24 years) and older (>=40 years) mothers are particularly susceptible to air pollution's effects on birth weight; (2) whether the relationship between air pollution and birth weight differed by infant sex; (3) confounding by co-pollutants and differences in pollutants' measurement frequencies; and (4) whether observed associations were influenced by inclusion of pre-term births. Findings did not indicate higher susceptibility to the relationship between air pollution and birth weight based on the mother's age or the infant's sex. Results were robust to exclusion of pre-term infants and co-pollutant adjustment, although sample size decreased for some pollutant pairs. These findings provide additional evidence for the relationship between air pollution and birth weight, and do not identify susceptible sub-populations based on infant sex or mother's age. We conclude with discussion of key challenges in research on air pollution and pregnancy outcomes.

    The EuroHOPE very low birth weight and very low for gestational age infants study aimed to measure and explain variation in mortality and length of stay (LoS) in the populations of seven European nations (Finland, Hungary, Italy (only the province of Rome), the Netherlands, Norway, Scotland and Sweden). Data were linked from birth, hospital discharge and mortality registries. For each infant basic clinical and demographic information, infant mortality and LoS at 1 year were retrieved. In addition, socio-economic variables at the regional level were used. Results based on 16,087 infants confirm that gestational age and Apgar score at 5 min are important determinants of both mortality and LoS. In most countries, infants admitted or transferred to third-level hospitals showed lower probability of death and longer LoS. In the meta-analyses, the combined estimates show that being male, multiple births, presence of malformations, per capita income and low population density are significant risk factors for death. It is essential that national policies improve the quality of administrative datasets and address systemic problems in assigning identification numbers at birth. European policy should aim at improving the comparability of data across jurisdictions. PMID:26633869

    This study was conducted to explore and identify factors associated with the practice of early introduction of solid, semi-solid or soft foods among infants aged 3–5 months in four Anglophone West African countries. Data sources for the analyses were the latest Demographic and Health Survey datasets of the 4 countries, namely Ghana (GDHS, 2008), Liberia (LDHS, 2007), Nigeria (NDHS, 2013) and Sierra Leone (SLDHS, 2008). Multiple logistic regression methods were used to analyze the factors associated with early introduction of solid, semi-solid or soft foods among infants aged 3–5 months, using individual-, household- and community-level determinants. The sample consisted of 2447 infants aged 3–5 months from four Anglophone West African countries: 166 in Ghana, 263 in Liberia, 1658 in Nigeria and 360 in Sierra Leone. Multivariable analyses revealed the individual factors associated with early introduction of solid, semi-solid or soft foods in these countries. These included increased infant’s age, diarrhea, acute respiratory infection and newborns perceived to be small by their mothers. Other predictors of early introduction of solid, semi-solid or soft foods were: mothers with no schooling, young mothers and fathers who worked in an agricultural industry. Public health interventions to improve exclusive breastfeeding practices by discouraging early introduction of solid, semi-solid or soft foods are needed in all 4 countries, targeting especially mothers at risk of introducing solid foods to their infants early.

    Infant body composition and postnatal weight gain have been implicated in the development of adult obesity and cardiovascular disease, but there are limited prospective data regarding the association between infant adiposity, postnatal growth and early cardiovascular parameters. Increased aortic intima-media thickness (aortic IMT) is an intermediate phenotype of early atherosclerosis. The aim of the present study was to investigate the relationship between weight and adiposity at birth, postnatal growth and aortic IMT. The Barwon Infant Study (n=1074 mother-infant pairs) is a population-derived birth cohort. Infant weight and other anthropometry were measured at birth and 6 weeks of age. Aortic IMT was measured by trans-abdominal ultrasound at 6 weeks of age (n=835). After adjustment for aortic size and other factors, markers of adiposity including increased birth weight (β=19.9 μm/kg, 95%CI 11.1, 28.6; P<0.001) and birth skinfold thickness (β=6.9 μm/mm, 95%CI 3.3, 10.5; P<0.001) were associated with aortic IMT at 6 weeks. The association between birth skinfold thickness and aortic IMT was independent of birth weight. In addition, greater postnatal weight gain was associated with increased aortic IMT, independent of birth weight and age at time of scan (β=11.3 μm/kg increase, 95%CI 2.2, 20.3; P=0.01). Increased infant weight and adiposity at birth, as well as increased early weight gain, were positively associated with aortic IMT. Excessive accumulation of adiposity during gestation and early infancy may have adverse effects on cardiovascular risk.

    Motor development and cognitive development in childhood have been found to be fundamentally interrelated, but less is known about the association extending over the life course. The aim of this study was to examine the association between early motor development and cognitive performance in early old age. From men and women belonging to the Helsinki Birth Cohort Study, who were born between 1934 and 1944 and resided in Finland in 1971, 1279 participated in cognitive performance tests (CogState®, version 3.0.5) between 2001 and 2006 at an average age of 64.2 years (SD 3.0). Of these, age at first walking extracted from child welfare clinic records was available for 398 participants. Longer reaction times in cognitive tasks measuring simple reaction time (SRT), choice reaction time (CRT), working memory (WM), divided attention (DA), and associated learning (AL) indicated poorer cognitive performance. Adjustment was made for sex, age at testing, father's occupational status and own highest attained education, and occupation in adulthood. Average age of learning to walk was 12.2 months (SD 2.1). After adjusting for covariates, earlier attainment of learning to walk was associated with shorter reaction times in cognitive performance tasks (SRT 10.32 % per month, 95 % CI 0.48-21.12, p = 0.039; CRT 14.17 % per month, 95 % CI 3.75-25.63, p = 0.007; WM 15.14 % per month, 95 % CI 4.95-26.32, p = 0.003). People who learned to walk earlier had better cognitive performance in early old age. The earlier attainment of motor skills may track over to early old age and possibly reflect greater cognitive reserve in older age. PMID:25929653

    There are limited data describing infant and young child feeding practices (IYCF) in urban Tanzania. This study assessed the types of foods consumed by children under 2 years of age and maternal exposure to promotions of these foods in Dar es Salaam, Tanzania. A cross-sectional survey was conducted among 305 mothers of children less than 24 months of age who attended child health services in October and November, 2014. Among infants less than 6 months of age, rates of exclusive breastfeeding were low (40.8%) and a high proportion (38.2%) received semi-solid foods. Continued breastfeeding among 20-23-month-olds was only 33.3%. Consumption of breastmilk substitutes was not prevalent, and only 3.9% of infants less than 6 months of age and 4.8% of 6-23 month-olds were fed formula. Among 6-23-month-olds, only 38.4% consumed a minimum acceptable diet (using a modified definition). The homemade complementary foods consumed by the majority of 6-23-month-olds (85.2%) were cereal-dominated and infrequently contained micronutrient-rich ingredients. Only 3.1% of 6-23-month-olds consumed commercially produced infant cereal on the day preceding the interview. In contrast, commercially produced snack foods were consumed by 23.1% of 6-23-month-olds. Maternal exposure to commercial promotions of breastmilk substitutes and commercially produced complementary foods was low (10.5% and 1.0%, respectively), while exposure to promotions of commercially produced snack foods was high (45.9%). Strategies are needed to improve IYCF practices, particularly with regard to exclusive and continued breastfeeding, increased dietary diversity and consumption of micronutrient-rich foods, and avoidance of feeding commercially produced snack foods.

    There are limited data describing infant and young child feeding practices (IYCF) in urban Tanzania. This study assessed the types of foods consumed by children under 2 years of age and maternal exposure to promotions of these foods in Dar es Salaam, Tanzania. A cross-sectional survey was conducted among 305 mothers of children less than 24 months of age who attended child health services in October and November, 2014. Among infants less than 6 months of age, rates of exclusive breastfeeding were low (40.8%) and a high proportion (38.2%) received semi-solid foods. Continued breastfeeding among 20-23-month-olds was only 33.3%. Consumption of breastmilk substitutes was not prevalent, and only 3.9% of infants less than 6 months of age and 4.8% of 6-23 month-olds were fed formula. Among 6-23-month-olds, only 38.4% consumed a minimum acceptable diet (using a modified definition). The homemade complementary foods consumed by the majority of 6-23-month-olds (85.2%) were cereal-dominated and infrequently contained micronutrient-rich ingredients. Only 3.1% of 6-23-month-olds consumed commercially produced infant cereal on the day preceding the interview. In contrast, commercially produced snack foods were consumed by 23.1% of 6-23-month-olds.

    Preterm delivery can precipitate maternal psychological morbidities. Family Nurture Intervention (FNI) was designed to minimize these by facilitating the emotional connection between mother and infant, beginning early in the infant's neonatal intensive care unit (NICU) stay. We examined depression and anxiety symptoms of mothers of preterm infants at 4 months infant corrected age (CA). One hundred fifteen mothers who delivered between 26 and 34 weeks gestational age were randomized to receive standard care (SC) or standard care plus FNI. Mothers' self-reported depressive symptoms (Center for Epidemiologic Studies Depression Scale: CES-D) and state anxiety (Spielberger State-Trait Anxiety Inventory: STAI) symptoms were assessed at enrollment, near to term age, and 4 months (CA). At 4 months CA, mean CES-D and STAI scores were significantly lower in FNI mothers compared to SC mothers. Effectiveness of FNI can only be evaluated as an integrated intervention strategy as it was not possible to control all aspects of FNI activities. Although there was considerable loss to follow-up, analyses suggest that resulting biases could have masked rather than inflated the measured effect size for depressive symptoms. FNI may be a feasible and practicable way to diminish the impact of premature delivery on maternal depressive and anxiety symptoms.

  9. Attempting to Honor Beliefs of Jehovah’s Witnesses at the Edge of Viability in an Infant Born at 23 Weeks’ Gestational Age

    Patient: Male, 23 weeks’ gestational age newborn Final Diagnosis: 23 weeks’ extreme prematurity • intraventricular hemorrhage • anemia • respiratory distress syndrome Symptoms: Hypotension • metabolic acidosis • tachycardia Medication: — Clinical Procedure: Transfusion of packed red blood cells Specialty: Pediatrics and Neonatology Objective: Rare disease Background: Infants born at 23 weeks’ gestation have a poor prognosis and require intensive care, including blood transfusions, to survive. Generally speaking, the decision to forgo life support is acceptable. Jehovah’s Witnesses believe that life is sacred and want lifesaving interventions except for blood transfusions. Therefore, an ethical dilemma exists when a baby is born on the edge of viability to parents that are Jehovah’s Witnesses. In this case, if parents and healthcare professionals disagree on the best interests of the child, the medical team should obtain a court order from the state to intervene. Case Report: We present the case of an infant born at 23 weeks’ gestation to parents who are Jehovah’s Witnesses. The parents wanted full life-support, except for blood transfusions, to be given. The clinical team obtained a court order to transfuse the infant. The infant unfortunately died despite all efforts. Conclusions: Currently, it is nearly impossible to honor the beliefs of Jehovah’s Witnesses to provide lifesaving treatments without blood transfusions for infants born at the border of viability. If the goal is to prolong life, the standard of care for a premature infant is for a doctor to obtain a court order to override the beliefs and wishes of Jehovah’s Witness parents and transfuse blood products as medically indicated. Although bloodless techniques for high-risk surgeries are under development, care for premature infants at 23 weeks’ gestation necessitates red cell transfusions. PMID:27255268

    Background: Perfluorocarboxylic acids (PFCAs) are environmentally and biologically persistent synthetic chemicals. PFCAs include perfluorooctanoic acid (PFOA; C8) and long-chain PFCAs (C9–C20). Studies examining long-chain PFCAs and fetal and postnatal growth are limited. Objectives: We investigated the associations of prenatal exposure to long-chain PFCAs with fetal and postnatal growth. Methods: For 223 Taiwanese mothers and their term infants, we measured PFOA and four long-chain PFCAs (ng/mL) in third-trimester maternal serum; infant weight (kg), length and head circumference (cm) at birth; and childhood weight and height at approximately 2, 5, 8, and 11 years of age. For each sex, we used multivariable linear regression to examine associations between ln-transformed prenatal PFCAs and continuous infant measures, and logistic regression to examine small for gestational age (SGA). Linear mixed models were applied to prenatal PFCAs and childhood weight and height z-scores. Results: In girls, prenatal perfluorononanoic acid (PFNA), perfluorodecanoic acid (PFDeA), perfluoroundecanoic acid (PFUnDA), and perfluorododecanoic acid (PFDoDA) concentrations were inversely associated with birth weight [e.g., βbirth weight (kg) = –0.06, 95% CI: –0.11, –0.01 per 1 ln-unit PFUnDA increase]; prenatal PFDeA and PFUnDA were associated with elevated odds of SGA; and PFDeA, PFUnDA, and PFDoDA were associated with lower average childhood height z-score. In boys, prenatal PFNA, and PFDoDA were associated with reductions in height at certain ages in childhood, but not with size at birth. Conclusions: Prenatal exposure to long-chain PFCAs may interfere with fetal and childhood growth in girls, and childhood growth in boys.

    The present study aimed to explore previously unreported ethnic differences in infant feeding practices during the introduction of solid foods, accounting for maternal and birth factors, and to determine whether these feeding patterns are associated with BMI at 3 years of age. An observational study using Poisson regression was carried out to investigate the relationship between ethnicity and infant feeding practices and linear regression was used to investigate the relationship between feeding practices and BMI at 3 years of age in a subsample of 1327 infants in Bradford. It was found that compared with White British mothers, mothers of Other ethnicities were less likely to replace breast milk with formula milk before introducing solid foods (adjusted relative risk (RR) - Pakistani: 0·76 (95 % CI 0·64, 0·91), Other South Asian: 0·58 (95 % CI 0·39, 0·86), and Other ethnicities: 0·50 (95 % CI 0·34, 0·73)). Pakistani and Other South Asian mothers were less likely to introduce solid foods early ( < 17 weeks) (adjusted RR - Pakistani: 0·92 (95 % CI 0·87, 0·96) and Other South Asian: 0·87 (95 % CI 0·81, 0·93)). Other South Asian mothers and mothers of Other ethnicities were more likely to continue breast-feeding after introducing solid foods (adjusted RR - 1·72 (95 % CI 1·29, 2·29) and 2·12 (95 % CI 1·60, 2·81), respectively). Pakistani and Other South Asian infants were more likely to be fed sweetened foods (adjusted RR - 1·18 (95 % CI 1·13, 1·23) and 1·19 (95 % CI 1·10, 1·28), respectively) and Pakistani infants were more likely to consume sweetened drinks (adjusted RR 1·72 (95 % CI 1·15, 2·57)). No association between infant feeding practices and BMI at 3 years was observed. Although ethnic differences in infant feeding practices were found, there was no association with BMI at 3 years of age. Interventions targeting infant feeding practices need to consider ethnicity to identify which populations are failing to follow

    The Breastfeeding, Antiretrovirals, and Nutrition (BAN) Study randomized HIV-infected mothers and their infants to receive either maternal lipid-based nutrient supplements (LNS) during lactation or no LNS and then to 1 of 3 antiretroviral drug (ARV) arms (maternal, infant, or no drugs). Assigned interventions were provided from 0 to 28 wk and all infants (n = 1619) were given LNS during (24–28 wk) and following (28–48 wk) weaning. This paper assesses the feasibility of infant LNS as a breastmilk replacement and uses longitudinal random effects models to examine associations of interventions, morbidity, and season with weight-for-age (WAZ), length-for-age (LAZ), and BMI-for-age (BMIZ) Z-scores from 24 to 48 wk. Infant LNS adherence was high (94.1% ate it daily). From 24 to 48 wk, mean WAZ (−0.42 to −0.76 SD; P < 0.001) and LAZ (−0.93 to −1.56 SD; P < 0.001) steadily declined, whereas BMIZ remained >0 throughout. A higher LAZ was associated with assignment to the maternal LNS arm (β=0.19; P < 0.05). Lower WAZ and BMIZ were associated with seasonal food insecurity (β=−0.08 and −0.09, respectively; both P < 0.001), fever (β=−0.07 and −0.13; both P < 0.001), diarrhea (β=−0.19 and −0.23; both P < 0.001), and assignment to the infant ARV arm (β=−0.17 and −0.17; both P < 0.05). The magnitude of the season and morbidity effects was small and BAN infants had higher weights and lengths than their counterparts in the general population. High LNS adherence and the modest impact of morbidity on growth indicate that LNS is a feasible breastmilk replacement for HIV-exposed infants weaned early, but controlled trials are needed to quantify the effects of LNS on growth in this population.

    2013-01-01

    Background Spontaneous intestinal perforation (SIP) is associated with the use of postnatal glucocorticoids and indometacin in extremely low birth weight (ELBW) infants. We hypothesized: 1) an association of SIP with the use of antenatal steroids (ANS) and indometacin either as prophylaxis for IVH (P Indo) or for treatment of PDA (Indo/PDA) and 2) an increased risk of death or abnormal neurodevelopmental outcomes in infants with SIP at 18-22 months corrected age. Design/Methods We retrospectively identified ELBW infants with SIP in the Neonatal Research Network’s generic database. Unadjusted analysis identified the differences in maternal, neonatal and clinical variables between infants with and without SIP. Logistic regression analysis identified the adjusted odds ratio for SIP with reference to ANS, P Indo and Indo/PDA. Neurodevelopmental outcomes were assessed among survivors at 18 to 22 months corrected age. Results Indo/PDA was associated with an increased risk of SIP (adjusted OR 1.61; 95% CI 1.25,2.08), while P Indo and ANS were not. SIP was independently associated with an increased risk of death or NDI (adjusted OR−1.85; 95% CI 1.32,2.60) and NDI among survivors (adjusted OR−1.75, 95% CI 1.20,2.55). Conclusion Indometacin used for IVH prophylaxis and ANS were not associated with the occurrence of SIP in ELBW infants. Indometacin used for treatment of symptomatic PDA was however associated with an increased risk of SIP. ELBW infants with SIP have an increased risk of poor neurodevelopmental outcomes.

    Infants are vulnerable: their growth and their development depend largely on their nutritional status. It is important to propose for them an optimal food. The human milk is unquestionably the best choice for the infant. When breastfeeding is not possible, the choice of the milk is made among hundreds of formulas for infants. They are regulated by a European directive. The healthcare professionals have to recommend as often as possible an infant formula: low protein content, predominance of whey proteins, enrichment with long chain fatty acids, lactose, addition of pre- or probiotics. The formulas for specific indications will be recommended in case of particular situations after verification that the complaints (constipation, regurgitations, stomach pains) cannot be corrected by simple dietary measures (increasing of the intakes of meals with a concomitant reduction of the volume of the meals). The food diversification is recommended between 17 and 26 weeks according to the neuromuscular capacities of the infant. These meals must be presented with a spoon to assure a sufficient nutritional intake. In Belgium, the use is to begin with fruits. One should avoid adding biscuits or sugar. The meal of vegetables will be introduced a little later. It should consist of starchy foods, vegetables with some fat to which the meat will be added. Numerous foods (biscuits, croissants and similar products, chips) should never be part of the ordinary menu, but should be reserved for particular occasions. The education of the children should begin from this age on.

    Objective. To identify factors affecting closure of patent ductus arteriosus (PDA) in newborn infants born at 22–27 weeks gestational age (GA) during pharmacological treatment with cyclooxygenase inhibitors. Method. Infants born at 22–27 weeks of GA between January 2006 and December 2009 who had been treated pharmacologically for PDA were identified retrospectively. Medical records were assessed for clinical, ventilatory, and outcome parameters. Echocardiographic examinations during treatment were reviewed. Results. Fifty-six infants were included in the study. Overall success rate of ductal closure with pharmacological treatment was 52%. Infants whose PDA was successfully closed had a higher GA (25 + 4 weeks versus 24 + 3 weeks; P = 0.047), and a higher pretreatment left to right maximal ductal flow velocity (1.6 m/s versus 1.1 m/s; P = 0.023). Correcting for GA, preeclampsia, antenatal steroids, and age at start of treatment, a higher maximal ductal flow velocity was still associated with successful ductal closure (OR 3.04; P = 0.049). Conclusion. Maximal ductal flow velocity was independently associated with success of PDA treatment. PMID:23316351

    Background: Serum creatinine (s[Cr]) reference ranges for very-low-birth-weight (VLBW) infants must account for physiologic changes in the first months of life. Methods: We retrospectively identified a sample of 218 appropriate-for-gestational age (GA) VLBW infants without risk factors for renal impairment, and classified into one of three GA groups: 25–27, 28–29, and 30–33 wk. We observed three phases of s[Cr] change (initial, decline, and equilibrium), whose characteristics varied by GA group. We used mixed-effects regression models to estimate mean and upper 95th prediction interval of s[Cr] for each GA group from birth to 34–36 wk post menstrual age (PMA). Results: In phase I, s[Cr] increased after birth, then returned slowly to baseline. The duration of phase I and the magnitude of s[Cr] rise decreased with increasing GA. In phase II, s[Cr] declined abruptly at a rate that increased with GA. A gradual transition to phase III, a steady-state equilibrium with similar s[Cr] among GA groups, began at approximately 34–36 wk PMA. We constructed GA group-specific nomograms depicting s[Cr] behaviour across the three phases. Conclusion: The reference ranges derived from a sample of infants without risk factors for renal impairment provide a context for quantitative interpretation of s[Cr] trends in VLBW infants.

    Regulation of visual attention is essential to learning about one's environment. Children with autism spectrum disorder (ASD) exhibit impairments in regulating their visual attention, but little is known about how such impairments develop over time. This prospective longitudinal study is the first to describe the development of components of visual attention, including engaging, sustaining, and disengaging attention, in infants at high-risk of developing ASD (each with an older sibling with ASD). Non-sibling controls and high-risk infant siblings were filmed at 6, 9, 12, 15, 18, 24, and 36 months of age as they engaged in play with small, easily graspable toys. Duration of time spent looking at toy targets before moving the hand toward the target and the duration of time spent looking at the target after grasp were measured. At 36 months of age, an independent, gold standard diagnostic assessment for ASD was conducted for all participants. As predicted, infant siblings subsequently diagnosed with ASD were distinguished by prolonged latency to disengage ('sticky attention') by 12 months of age, and continued to show this characteristic at 15, 18, and 24 months of age. The results are discussed in relation to how the development of visual attention may impact later cognitive outcomes of children diagnosed with ASD. PMID:24004846

    Objectives Under the prevailing conditions of imbalanced life table and historic gender discrimination in India, our study examines crossover between life expectancies at ages zero, one and five years for India and quantifies the relative share of infant and under-five mortality towards this crossover. Methods We estimate threshold levels of infant and under-five mortality required for crossover using age specific death rates during 1981–2009 for 16 Indian states by sex (comprising of India’s 90% population in 2011). Kitagawa decomposition equations were used to analyse relative share of infant and under-five mortality towards crossover. Findings India experienced crossover between life expectancies at ages zero and five in 2004 for menand in 2009 for women; eleven and nine Indian states have experienced this crossover for men and women, respectively. Men usually experienced crossover four years earlier than the women. Improvements in mortality below ages five have mostly contributed towards this crossover. Life expectancy at age one exceeds that at age zero for both men and women in India except for Kerala (the only state to experience this crossover in 2000 for men and 1999 for women). Conclusions For India, using life expectancy at age zero and under-five mortality rate together may be more meaningful to measure overall health of its people until the crossover. Delayed crossover for women, despite higher life expectancy at birth than for men reiterates that Indian women are still disadvantaged and hence use of life expectancies at ages zero, one and five become important for India. Greater programmatic efforts to control leading causes of death during the first month and 1–59 months in high child mortality areas can help India to attain this crossover early. PMID:26683617

    Introduction We present our experience with the use of semirigid ureteroscopy for the treatment of ureteric stones in children less than or equal to 6 years of age. Material and methods The records of 21 children (12 female, 9 male) with an average age of 4.7 years (range 8 months to 6 years) treated with semirigid ureteroscopy between June 2006 and July 2010 were reviewed. In 13 ureteral units 7Fr semirigid ureteroscopy was carried out in a retrograde manner to treat stone disease, while an adult ureteroscope (9.5 fr) was used in the remaining patients. Stones were located in the upper ureter in 2 cases, middle ureter in 2 cases, and lower ureter in 17 cases. Ureteral dilation was not required in all patients. Results Stone size varied from 4 to 13 mm (mean 6 mm). The management of stones in 18 (90.7%) children was straightforward and a single ureteroscopy was required to clear the ureters. In 2 (6.2%) children, repeat ureteroscopy was undertaken to render the ureters stone free, and in 1 child (3.1%) it was not possible to remove the stone. Stones were fragmented with pneumatic lithotripsy in 12 cases and stones were removed mechanically without fragmentation in the remaining 9 cases. Intraoperative complications occurred in 2 (9.3%) children and included extravasation (1 patient), which was managed with ureteral stenting and stone upward migration (1 patient). Early postoperative complications included pyelonephritis (1 patient). Mean follow-up was 6.4 (3-36) months. Incidence of stricture at the site of stone impaction was not detected in any patients. None of the patients managed without a post-operative stent required subsequent intervention. Conclusions In the hands of an experienced surgeon, ureteroscopy in young children can be a safe and efficient treatment for ureteral stones that can be performed without ureteral dilation. Routine ureteral stenting is not a requirement when the procedure is relatively atraumatic. Further studies and longer follow-up are

    In March 2015, a ground vehicle gravimetry test was implemented in eastern Changsha to assess the repeatability and accuracy of ground vehicle SINS/GNSS gravimeter—SGA-WZ02. The gravity system developed by NUDT consisted of a Strapdown Inertial Navigation System (SINS), a Global Navigation Satellite System (GNSS) remote station on test vehicle, a GNSS static master station on the ground, and a data logging subsystem. A south-north profile of 35 km along the highway in eastern Changsha was chosen and four repeated available measure lines were obtained. The average speed of a vehicle is 40 km/h. To assess the external ground gravity disturbances, precise ground gravity data was built by CG-5 precise gravimeter as the reference. Under relative smooth conditions, internal accuracy among repeated lines shows an average agreement at the level of 1.86 mGal for half wavelengths about 1.1 km, and 1.22 mGal for 1.7 km. The root-mean-square (RMS) of difference between calculated gravity data and reference data is about 2.27 mGal/1.1 km, and 1.74 mGal/1.7 km. Not all of the noises caused by vehicle itself and experiments environments were eliminated in the primary results. By means of selecting reasonable filters and improving the GNSS observation conditions, further developments in ground vehicle gravimetry are promising. PMID:26389916

The gravity system developed by NUDT consisted of a Strapdown Inertial Navigation System (SINS), a Global Navigation Satellite System (GNSS) remote station on test vehicle, a GNSS static master station on the ground, and a data logging subsystem. A south-north profile of 35 km along the highway in eastern Changsha was chosen and four repeated available measure lines were obtained. The average speed of a vehicle is 40 km/h. To assess the external ground gravity disturbances, precise ground gravity data was built by CG-5 precise gravimeter as the reference. Under relative smooth conditions, internal accuracy among repeated lines shows an average agreement at the level of 1.86 mGal for half wavelengths about 1.1 km, and 1.22 mGal for 1.7 km. The root-mean-square (RMS) of difference between calculated gravity data and reference data is about 2.27 mGal/1.1 km, and 1.74 mGal/1.7 km. Not all of the noises caused by vehicle itself and experiments environments were eliminated in the primary results. By means of selecting reasonable filters and improving the GNSS observation conditions, further developments in ground vehicle gravimetry are promising.

    The study of twin behavior offers the opportunity to study differential patterns of social and communicative interactions in a context where the adult partner and same-age peer are equally familiar. We investigated the development of social engagement, communicative gestures, and imitation in 7- to 25-month-old twins. Twin dyads (N=20 pairs) participated in 10-min, semi-structured play sessions, with the mother seated in a chair completing paperwork for half the session, and on the floor with her children for the other half. Overall, twins engaged more with their mothers than with their siblings: they showed objects and imitated speech and object use more frequently when interacting with their mothers than with their siblings. When the mother was otherwise engaged, the twins played with toys separately, observed each other's toy play, or were unengaged. These results demonstrate that adult scaffolding of social interactions supports increased communicative bids even in a context where both familiar peers and adults are available as communicative partners.

    In a prospective-longitudinal study, prevalence rates of otitis media with effusion (OME) were analysed in 150 healthy-born and 100 high-risk-born infants, aged 0-2 years. In order to determine OME, otoscopy and tympanometry were performed at 3-monthly intervals beginning at term date. The Maastricht Otitis Media with Effusion Study (MOMES) algorithm was used to standardize the diagnosis. The distribution of relevant background characteristics was similar in both groups except for gestational age and birth weight, which were significantly lower (P < 0.001) in the high-risk-born group. The ratio of unilateral:bilateral OME was 2:3. Prevalence rates of OME were strongly associated with age (P < 0.001). During the first months of life, OME prevalence rates increased rapidly in both groups, but did not differ significantly. However, from the age of 6 months on, OME prevalence rates of the high-risk group became significantly higher compared with the normal group (P < 0.05). The peak prevalence of OME (59% in the high-risk group versus 49% in the normal group) was observed around the age of 10 months. Although gradually decreasing prevalence rates were noted in both groups with aging, the differences between high-risk and normal infants remained, at least up to 24 months. In conclusion, OME is a very prevalent, age-dependent disorder during infancy, especially in high-risk infants. Peak prevalence of OME was found in the second half of the first year of life.

    Objective Infants born small for gestational age (SGA) or preterm have increased rates of perinatal morbidity and mortality. Stressful events have been suggested as potential contributors to preterm birth (PB) and low birth weight (LBW). We studied the effect of the 2008 economic collapse in Iceland on the risks of adverse birth outcomes. Study design The study population constituted all Icelandic women giving birth to live-born singletons from January 1st 2006 to December 31st 2009. LBW infants were defined as those weighing <2500 grams at birth, PB infants as those born before 37 weeks of gestation and SGA as those with a birth weight for gestational age more than 2 standard deviations (SD's) below the mean according to the Swedish fetal growth curve. We used logistic regression analysis to estimate odds ratios [OR] and corresponding 95 percent confidence intervals [95% CI] of adverse birth outcomes by exposure to calendar time of the economic collapse, i.e. after October 6th 2008. Results Compared to the preceding period, we observed an increased adjusted odds in LBW-deliveries following the collapse (aOR = 1.24, 95% CI [1.02, 1.52]), particularly among infants born to mothers younger than 25 years (aOR = 1.85, 95% CI [1.25, 2.72]) and not working mothers (aOR = 1.61, 95% CI [1.10, 2.35]). Similarly, we found a tendency towards higher incidence of SGA-births (aOR = 1.14, 95% CI [0.86, 1.51]) particularly among children born to mothers younger than 25 years (aOR = 1.87, 95% CI [1.09, 3.23]) and not working mothers (aOR = 1.86, 95% CI [1.09, 3.17]). No change in risk of PB was observed. The increase of LBW was most distinct 6–9 months after the collapse. Conclusion The results suggest an increase in risk of LBW shortly after the collapse of the Icelandic national economy. The increase in LBW seems to be driven by reduced fetal growth rate rather than shorter gestation. PMID:24324602

    Extremely low birth weight (ELBW) infants (<1 kg) have high rates of neurodisability. Although previous studies have implicated placental lesions in adverse short-term neurologic outcomes in this population, none have assessed their effects in these children once they reach school age. We conducted a secondary analysis of placental pathology in a cohort study of inborn singleton ELBW infants born between 1992 and 1995 and evaluated for cerebral palsy (CP) and abnormal neurocognitive testing at 8 years of age (N = 129). The neurocognitive tests were the Kaufman Assessment Battery for Children (K-ABC) and 6 subtests of the NEPSY: A Developmental Neuropsychological Assessment. We found that placental lesions associated with maternal vascular underperfusion (increased syncytial knots and acute atherosis) were risk factors for CP, while villous edema was associated with low scores on both neurocognitive tests. Histologic chorioamnionitis (HCA) was not predictive of outcome in the population as a whole, but a severe fetal vascular response was associated with a lower NEPSY score in the subpopulation with HCA (N = 69). Placentas with increased syncytial knots, villous edema, and those with neither finding constituted nonoverlapping subgroups with distinct pathologic and perinatal characteristics. Among infants with villous edema (N = 25), those with neurologic impairment had lower gestational ages and more severe degrees of HCA. However, by logistic regression these other factors were not independent risk factors for abnormal neurocognitive testing, and only HCA with a severe fetal vascular response decreased the association of villous edema with low test scores for NEPSY, but not K-ABC.

    Anemia affects one-quarter of the world's population, but its etiology remains poorly understood. We determined the prevalence of anemia and studied underlying risk factors in infants (6-23 months), young school-aged children (6-8 years), and young non-pregnant women (15-25 years) in south-central Côte d'Ivoire. Blood, stool, and urine samples were subjected to standardized, quality-controlled methods. We found high prevalence of anemia, malaria, inflammation, and deficiencies of iron, riboflavin, and vitamin A but low prevalence and intensities of soil-transmitted helminth and schistosome infections. Multivariate regression analysis revealed significant associations between anemia and Plasmodium falciparum for infants, inflammation for school-aged children, and cellular iron deficiency for both school-aged children and non-pregnant women. Women with riboflavin deficiency had significantly lower odds of anemia. Our findings call for interventions to protect infants from malaria, improved intake of dietary iron, better access to health care, and health education.

    Background To elucidate the role of prenatal, neonatal and early postnatal variables in influencing the achievement of full enteral feeding (FEF) in very low birth weight (VLBW) infants and to determine whether neonatal intensive care units (NICUs) differ in this outcome. Methods Population-based retrospective cohort study using data on 1,864 VLBW infants drawn from the “Emilia-Romagna Perinatal Network” Registry from 2004 to 2009. The outcome of interest was time to FEF achievement. Eleven prenatal, neonatal and early postnatal variables and the study NICUs were selected as potential predictors of time to FEF. Parametric survival analysis was used to model time to FEF as a function of the predictors. Marginal effects were used to obtain adjusted estimates of median time to FEF for specific subgroups of infants. Results Lower gestational age, exclusive formula feeding, higher CRIB II score, maternal hypertension, cesarean delivery, SGA and PDA predicted delayed FEF. NICUs proved to be heterogeneous in terms of FEF achievement. Newborns with PDA had a 4.2 days longer predicted median time to FEF compared to those without PDA; newborns exclusively formula-fed had a 1.4 days longer time to FEF compared to those fed human milk. Conclusions The results of our study suggest that time to FEF is influenced by clinical variables and NICU-specific practices. Knowledge of the variables associated with delayed/earlier FEF achievement could help in improving specific aspects of routine clinical management of VLBW infants and to reduce practice variability.

    Objective: Preterm infants are exposed to the visual environment earlier than fullterm infants, but whether early exposure affects later development is unclear. Our aim was to investigate whether the development of visual disengagement capacity during the first 6 months postterm was associated with cognitive and motor outcomes at school age, and whether associations differed between fullterms and low-risk preterms. Method: Seventeen fullterms and ten low-risk preterms were tested in a gaze shifting task every 4 weeks until 6 months postterm. The longitudinal data were converted into single continuous variables by fitting the data with an S-shaped curve (frequencies of looks) or an inverse model (latencies of looks). Neuropsychological test results at school age were converted into composite z scores. We then performed linear regression analyses for each functional domain at school age with the variables measuring infant visual attention as separate predictors and adjusting for maternal level of education and group (fullterms versus preterms). We included an interaction term, visual attention*group, to determine whether predictive relations differed between fullterms and preterms. Results: A slower development of disengagement predicted poorer performance on attention, motor skills, and handwriting, irrespective of fullterm or preterm birth. Predictive relationships differed marginally between fullterms and preterms for inhibitory attentional control (P = 0.054) and comprehensive reading (P = 0.064). Conclusion: This exploratory study yielded no indications of a clear advantage or disadvantage of the extra visual exposure in healthy preterm infants. We tentatively conclude that additional visual exposure does not interfere with the ongoing development of neuronal networks during this vulnerable period of brain development. PMID:25340045

    Purpose Retinoblastoma is the most common primary malignant intra-ocular tumor in children. Although intra-arterial chemotherapy (IAC) by selectively infusing chemotherapy through the ophthalmic artery has become an essential technique in the treatment of advanced intra-ocular retinoblastoma in children, the outcome of IAC as primary therapy for infants less than 3 months of age remains unknown. In this retrospective study, we reviewed the outcome of IAC as primary therapy for retinoblastoma in infants less than 3 months of age. Methods We retrospectively reviewed ten retinoblastoma patients attending our center from January 2009 to September 2015 and beginning primary IAC before the age of 3 months. The patient characteristics, overall outcomes and therapy-related complications were assessed. Results The mean patient age at the first IAC treatment was 10.4 weeks (range 4.9–12.9 weeks). These eyes were classified according to the International Classification of Retinoblastoma (ICRB) as group A (n = 0), B (n = 2), C (n = 0), D (n = 9), or E (n = 2). A total of 28 catheterizations were performed, and the procedure was stopped in one patient because of internal carotid artery spasm. Each eye received a mean of 2.6 cycles of IAC (range 2–4 cycles). After IAC with a mean follow-up of 28.3 months (range 9–65 months), tumor regression was observed in 12 of 13 eyes. One eye was enucleated due to tumor progression. All patients are alive and no patient has developed metastatic disease or other malignancies. Conclusions Our experience suggests IAC as primary therapy is a feasible and promising treatment for retinoblastoma in infants less than 3 months of age. PMID:27504917

    Background: By school-age, even low-risk moderately preterm-born children show more neuro-cognitive deficits, motor impairments, academic underachievement, behavioral problems, and poor social adaptation than full-term peers. Aim: To evaluate the outcomes at school-age for moderately preterm-born children (29-33 weeks gestational age), appropriate in growth for gestational age (AGA) and medically at low-risk, randomized to Newborn Individualized Developmental Care and Assessment Program (NIDCAP) or standard care in the Newborn Intensive Care Unit. At school-age, the experimental (E) group will show better neuropsychological and neuro-electrophysiological function, as well as improved brain structure than the control (C) group. Materials and Methods: The original sample consisted of 30 moderately preterm-born infants (29 to 33 weeks), 23 (8C and 15E) of them were evaluated at 8 years of age, corrected-for-prematurity with neuropsychological, EEG spectral coherence, and diffusion tensor magnetic resonance imaging (DT-MRI) measures. Results: E-performed significantly better than C-group children on the Kaufman Assessment Battery for Children-Second Edition (KABC-II) and trended towards better scores on the Rey-Osterrieth Complex Figure Test. They also showed more mature frontal and parietal brain connectivities, and more mature fiber tracts involving the internal capsule and the cingulum. Neurobehavioral results in the newborn period successfully predicted neuropsychological functioning at 8 years corrected age. Conclusion: Moderately preterm infants cared for with the NIDCAP intervention showed improved neuropsychological and neuro-electrophysiological function as well as improved brain structure at school-age.

    The paper presented the possibility of recognition by adult the comfort and discomfort state of 3 and 6 months old infant's on the base of their vocalizations. The acoustic features of the vocalizations that are important for the recognition of the infant state of the characteristics of voice was described. It is shown that discomfort vocalizations differ from comfort ones on the basis of the average and maximum values of pitch, pitch values in the central and final part of the vocalization. A mathematical model is proposed and described a classification function signal of discomfort and comfort. Was found that the vocalizations of infants attributable adults with a probability of 0.75 and above the categories of comfort and discomfort with high reliability are recognized by the mathematical model based on a classification function.

  18. Obesity and diabetes genes are associated with being born small for gestational age: Results from the Auckland Birthweight Collaborative study

    2010-01-01

    Background Individuals born small for gestational age (SGA) are at increased risk of rapid postnatal weight gain, later obesity and diseases in adulthood such as type 2 diabetes, hypertension and cardiovascular diseases. Environmental risk factors for SGA are well established and include smoking, low pregnancy weight, maternal short stature, maternal diet, ethnic origin of mother and hypertension. However, in a large proportion of SGA, no underlying cause is evident, and these individuals may have a larger genetic contribution. Methods In this study we tested the association between SGA and polymorphisms in genes that have previously been associated with obesity and/or diabetes. We undertook analysis of 54 single nucleotide polymorphisms (SNPs) in 546 samples from the Auckland Birthweight Collaborative (ABC) study. 227 children were born small for gestational age (SGA) and 319 were appropriate for gestational age (AGA). Results and Conclusion The results demonstrated that genetic variation in KCNJ11, BDNF, PFKP, PTER and SEC16B were associated with SGA and support the concept that genetic factors associated with obesity and/or type 2 diabetes are more prevalent in those born SGA compared to those born AGA. We have previously determined that environmental factors are associated with differences in birthweight in the ABC study and now we have demonstrated a significant genetic contribution, suggesting that the interaction between genetics and the environment are important.

    Most work on listeners' ability to separate streams of speech has focused on adults. Yet infants also find themselves in noisy environments. In order to learn from their caregivers' speech in these settings, they must first separate it from background noise such as that from television shows and siblings. Previous work has found that 7.5-month-old infants can separate streams of speech when the target voice is more intense than the distractor voice (Newman and Jusczyk, 1996), when the target voice is known to the infant (Barker and Newman, 2000) or when infants are presented with an audiovisual (rather than auditory-only) signal (Hollich, Jusczyk, and Newman, 2001). Unfortunately, the paradigm in these studies can only be used on infants at least 7.5 months of age, limiting the ability to investigate how stream segregation develops over time. The present work uses a new paradigm to explore younger infants' ability to separate streams of speech. Infants aged 4.5 months heard a female talker repeat either their own name or another infants' name, while several other voices spoke fluently in the background. We present data on infants' ability to recognize their own name in this cocktail party situation. [Work supported by NSF and NICHD.

    Early exiting from the labor force and into disability pension (DP) represents a major social problem in Sweden and elsewhere. We examined how being asymmetric (A-SGA) or symmetric (S-SGA) small for gestational age predicts transitioning into DP. We analyzed a longitudinal sample of 8125 men and women from the Stockholm Birth Cohort (SBC), born in 1953 and not on DP in 1990. The SBC consists of data from various sources, including self-reported information and data from administrative registers. The follow-up period was from 1991 to 2009. Yearly information on the receipt of DP benefits from register data was operationalized as a dichotomous variable. 13 percent of the sample moved into DP during follow-up. Cox proportional hazards regression was used to examine whether disadvantageous fetal growth--A-SGA and S-SGA--predicted DP. Men and women born A-SGA had a substantially increased hazard of DP. The full model suggested a hazard ratio of 1.68 (CI: 1.11-2.54), only being affected slightly by adulthood conditions. Several childhood conditions were also associated with DP. Such factors, however, mainly affected DP risk through adulthood conditions. The effect of SGA on DP appeared particularly strong among individuals from socioeconomically disadvantaged backgrounds. The evidence presented suggests that being A-SGA influences the risk of DP, independent of childhood and adulthood conditions, and similarly for men and women. Due to A-SGA being rather infrequent, reducing the occurrence of A-SGA would, however, only have a marginal impact on the stock of DP pensioners. For the individual affected, the elevation in the risk of DP was nevertheless substantial. Other childhood conditions exercised a larger influence on the stock of DP recipients, but they mostly operated through adulthood attainment. The importance of socioeconomic resources in childhood for the long term health consequences of SGA is interesting from a policy perspective and warrants further research

    Thrombocytopenia is a common finding in small for gestational age (SGA) neonates and is thought to result from a unique pathophysiologic mechanism related to chronic intrauterine hypoxia. Our objective was to estimate the incidence and severity of early-onset thrombocytopenia in SGA neonates, and to identify risk factors for thrombocytopenia. We performed a retrospective cohort study of all consecutive SGA neonates admitted to our ward and a control group of appropriate for gestational age (AGA) neonates matched for gestational age at birth. Main outcome measures were incidence and severity of thrombocytopenia, hematological and clinical risk factors for thrombocytopenia, and bleeding. A total of 330 SGA and 330 AGA neonates were included, with a mean gestational age at birth of 32.9 ± 4 weeks. Thrombocytopenia (<150x109/L) was found in 53% (176/329) of SGA neonates and 20% (66/330) of AGA neonates (relative risk (RR) 2.7, 95% confidence interval (CI) [2.1, 3.4]). Severe thrombocytopenia (21-50x109/L) occurred in 25 neonates (8%) in the SGA and 2 neonates (1%) in the AGA group (RR 12.5, 95% CI [3.0, 52.5]). Platelet counts <20x109/L were not recorded. Within the SGA group, lower gestational age at birth (p = <0.01) and erythroblastosis (p<0.01) were independently associated with a decrease in platelet count. Platelet count was positively correlated with birth weight centiles. In conclusion, early-onset thrombocytopenia is present in over 50% of SGA neonates and occurs 2.7 times as often as in AGA neonates. Thrombocytopenia is seldom severe and is independently associated with lower gestational age at birth and erythroblastosis. PMID:27177157

    Growth restriction in utero during a period that is critical for normal growth of the brain, has previously been associated with deviations in cognitive abilities and brain anatomical and functional changes. We measured magnetoencephalography (MEG) in 4- to 7-year-old children to test if children born small for gestational age (SGA) show deviations in resting-state brain oscillatory activity. Children born SGA with postnatally spontaneous catch-up growth [SGA+; six boys, seven girls; mean age 6.3 year (SD = 0.9)] and children born appropriate for gestational age [AGA; seven boys, three girls; mean age 6.0 year (SD = 1.2)] participated in a resting-state MEG study. We calculated absolute and relative power spectra and used non-parametric statistics to test for group differences. SGA+ and AGA born children showed no significant differences in absolute and relative power except for reduced absolute gamma band power in SGA children. At the time of MEG investigation, SGA+ children showed significantly lower head circumference (HC) and a trend toward lower IQ, however there was no association of HC or IQ with absolute or relative power. Except for reduced absolute gamma band power, our findings suggest normal brain activity patterns at school age in a group of children born SGA in which spontaneous catch-up growth of bodily length after birth occurred. Although previous findings suggest that being born SGA alters brain oscillatory activity early in neonatal life, we show that these neonatal alterations do not persist at early school age when spontaneous postnatal catch-up growth occurs after birth.

    In this study, the Vaccine Adverse Event Reporting System (VAERS) database, 1990–2010, was investigated; cases that specified either hospitalization or death were identified among 38,801 reports of infants. Based on the types of vaccines reported, the actual number of vaccine doses administered, from 1 to 8, was summed for each case. Linear regression analysis of hospitalization rates as a function of (a) the number of reported vaccine doses and (b) patient age yielded a linear relationship with r 2 = 0.91 and r 2 = 0.95, respectively. The hospitalization rate increased linearly from 11.0% (107 of 969) for 2 doses to 23.5% (661 of 2817) for 8 doses and decreased linearly from 20.1% (154 of 765) for children aged <0.1 year to 10.7% (86 of 801) for children aged 0.9 year. The rate ratio (RR) of the mortality rate for 5–8 vaccine doses to 1–4 vaccine doses is 1.5 (95% confidence interval (CI), 1.4–1.7), indicating a statistically significant increase from 3.6% (95% CI, 3.2–3.9%) deaths associated with 1–4 vaccine doses to 5.5% (95% CI, 5.2–5.7%) associated with 5–8 vaccine doses. The male-to-female mortality RR was 1.4 (95% CI, 1.3–1.5). Our findings show a positive correlation between the number of vaccine doses administered and the percentage of hospitalizations and deaths. Since vaccines are given to millions of infants annually, it is imperative that health authorities have scientific data from synergistic toxicity studies on all combinations of vaccines that infants might receive. Finding ways to increase vaccine safety should be the highest priority. PMID:22531966

    Acoustic-phonetic exaggeration of infant-directed speech (IDS) is well documented, but few studies address whether these features are modified with a child's age. Mandarin-speaking mothers were recorded while addressing an adult and their child at two ages (7-12 months and 5 years) to examine the acoustic-phonetic differences between IDS and child–directed speech (CDS). CDS exhibits an exaggeration pattern resembling that of IDS—expanded vowel space, longer vowels, higher pitch, and greater lexical tone differences—when compared to ADS. Longitudinal analysis demonstrated that the extent of acoustic exaggeration is significantly smaller in CDS than in IDS. Age-related changes in maternal speech provide some support for the hypothesis that mothers adjust their speech directed toward children as a function of the child's language ability. PMID:19232142

    Supplementation with folic acid (FA) was proven to prevent neural tube defects (NTDs) and was recommended worldwide before and during early pregnancy. However, much less is known regarding the role of FA after the 12th gestational week (GW). This study aimed to investigate the related effects of continued FA supplementation after the first trimester of pregnancy on fetal growth. The study subjects came from the Ma'anshan-Anhui Birth Cohort Study (MABC) that recruited 3474 pregnant women from the city of Ma'anshan in Anhui Province in China during the period of May 2013 to September 2014. The information on use of vitamin and mineral supplements was recorded in different periods (the first/second/third trimester of pregnancy). Small-for-gestational-age (SGA) births were live-born infants that were <10th percentile of birth weight, and large-for-gestational-age (LGA) births were live-born infants that were ≥90th percentile of birth weight according to nomograms based on gender and gestational age from the latest standards. We used multivariable logistic regression to evaluate the effects of FA supplement consumption in the second/third trimester of pregnancy on the risk of LGA and SGA. In addition, propensity score analysis was also performed to examine the effects. In this prospective birth cohort study conducted in Chinese women who had taken FA in the first trimester of pregnancy, we found that continued FA supplementation with 400 micrograms/day in the second and third trimesters of pregnancy significantly increased the risk of LGA (RR = 1.98 (1.29, 3.04)). This relation was strong or monotonic after adjusting for maternal age, newborn's gender, maternal pre-pregnancy BMI, maternal education level, smoking, alcohol consumption and calcium supplementation. We did not observe that continuing FA supplementation after the first trimester of pregnancy remarkably decreased the risk of SGA. The propensity score analysis showed similar results.

    Prior research indicates that being reared in stressful environments is associated with earlier onset of menarche in girls. In this research, we examined (a) whether these effects are driven by exposure to certain dimensions of stress (harshness or unpredictability) during the first 5 years of life and (b) whether the negative effects of stress on the timing of menarche are buffered by secure infant-mother attachment. Results revealed that (a) exposure to greater harshness (but not unpredictability) during the first 5 years of life predicted earlier menarche and (b) secure infant-mother attachment buffered girls from this effect of harsh environments. By connecting attachment research to its evolutionary foundations, these results illuminate how environmental stressors and relationships early in life jointly affect pubertal timing. PMID:26980153

    Following the 2008 Wenchuan earthquake, the Chinese government instituted an infant and young and child nutrition program that included promotion of in-home fortification of complementary food with ying yang bao (YYB), a soy-based powder containing iron, 2.5 mg as iron-EDTA and 5 mg as ferrous fumarate, and other micronutrients. Ying yang bao was provided to participating families in 8 poor rural counties in Sichuan, Shaanxi, and Gansu provinces by the Ministry of Health. We assessed hemoglobin levels among infants and young children (IYC) aged 6 to 23 months at baseline in May 2010 (n = 1290) and during follow-up in November 2010 (n = 1142), May 2011 (n = 1118), and November 2011 (n = 1040), using the Hemocue method. Interviewers collected basic demographic information and child feeding practices from the children's caretakers. Altitude-adjusted hemoglobin level averaged 10.8 g/dL, and total anemia prevalence was 49.5% at baseline. Average hemoglobin was 11.3 g/dL at 6 months, 11.6 g/dL at 12 months, and 11.7 g/dL at 18 months after introduction of YYB. Moderate anemia (hemoglobin: 70-99 g/dL) decreased from 20.3% at baseline to 7.5%, 5.8%, and 7.3% after 6, 12, and 18 months of home fortification, respectively (P < .001), whereas mild anemia (hemoglobin: 100-110 g/dL) decreased from 29.0% to 16.7%, 18.1%, and 15.4%, respectively (P < .001). Among infants aged 6 to 23 months, 95% had regularly been fed YYB during the observation period. Regression analysis showed that the duration of YYB consumption and number of sachets consumed per week correlated positively with hemoglobin levels and negatively with anemia rates. Home food fortification with YYB is feasible and effective for nutrition promotion among IYC in high-risk regions of China.

    ABSTRACT Objectives: The aim of the study was to review published evidence and the opinion of practising clinicians on the prevalence and long-term health consequences of functional gastrointestinal symptoms in infants younger than 12 months. Methods: PubMed was searched from inception to November 2014 to find articles reporting the prevalence and long-term health outcomes of infantile colic, regurgitation, functional constipation, functional diarrhoea, and dyschezia in infants younger than <12 months. A questionnaire was sent to practising clinicians worldwide, and a group of 15 international experts met to discuss the likely frequency and longer-term consequences of these symptoms. Results: The literature search identified 30 studies reporting the prevalence of infantile colic (2%–73%), 13 that of regurgitation (3%–87%), 8 that of functional constipation (0.05%–39.3%), 2 that of functional diarrhoea (2%–4.1%), and 3 that of dyschezia (0.9%–5.6%). The studies varied in design, populations investigated, and definition of the symptoms. Questionnaires were received from 369 respondents. The experts agreed that the likely prevalences for colic, regurgitation, and functional constipation were 20%, 30%, and 15%, respectively. The limited data in the literature for functional diarrhoea and dyschezia suggest prevalences <10%. Infantile colic may be associated with future health problems in a subset of infants. Conclusions: Functional gastrointestinal symptoms appear to occur in a significant proportion of infants younger than 12 months and may have an impact on future health outcomes. Prospective collection of data according to agreed criteria is needed to obtain more accurate estimates of the prevalence and consequences of these symptoms. PMID:26308317

  16. Association of Maternal and Infant Salivary Testosterone and Cortisol and Infant Gender With Mother-Infant Interaction in Very-Low-Birthweight Infants.

    Male very-low-birthweight (VLBW) infants are more prone than females to health and developmental problems and less positive mother-infant interactions. Because gender differences in brain development and social relationships suggest hormonal influences on quality of mother-infant interaction, the authors explored the associations of maternal and infant salivary testosterone and cortisol levels with mother-infant interactions in the sample as a whole and by gender, after controlling for covariates. Data were collected prospectively from 62 mothers and their VLBW infants through infant record review, maternal interview, biochemical measurement of both mothers and infants, and observation of mother-infant interactions at 40 weeks postmenstrual age and at three and six months corrected age. Infants' positive interactions increased and mothers' decreased from three to six months. In generalized estimating equation (GEE) analyses, after controlling for covariates, higher maternal testosterone and infant cortisol were associated with more positive and more frequent maternal interactive behaviors. In GEE analyses by infant gender, after controlling for covariates, effects of maternal and infant hormone levels became more significant, especially on infants' interactive behaviors. Based on these preliminary findings, among VLBW infants, males with high testosterone are expected to have less positive mother-infant interactions than males with low testosterone or female infants.

    The main usefulness of video electroencephalographic (video-EEG) monitoring lies in the fact that it allows proper classification of the type of epileptic seizure and epileptic syndrome, identification of minor seizures, location of the epileptogenic zone and differentiation between epileptic seizures and non-epileptic paroxysmal manifestations (NEPM). In infants and pre-school age children, the clinical signs with which epileptic seizures are expressed differ to those of older children, seizures with bilateral motor signs such as epileptic spasms, tonic and myoclonic seizures predominate, and seizures with interruption of activity or hypomotor seizures, and no prominent automatisms are observed. In children with focal epilepsies, focal and generalised signs are often superposed, both clinically and in the EEG. NEPM may be benign transitory disorders or they can be episodic symptoms of different neurological or psychopathological disorders. NEPM are often observed in children with mental retardation, neurological compromise or autism spectrum disorders, who present epileptic seizures and epileptiform abnormalities in the baseline EEG. It then becomes necessary to determine which episodes correspond to epileptic seizures and which do not. The NEPM that are most frequently registered in the video-EEG in infants and pre-school age children are unexpected sudden motor contractions ('spasms'), introspective tendencies, motor stereotypic movements and paroxysmal sleep disorders.

    The aim of this study is to develop a specific formula for the purpose of assessing skeletal age in a sample of Italian growing infants and children by measuring carpals and epiphyses of radio and ulna. A sample of 332 X-rays of left hand-wrist bones (130 boys and 202 girls), aged between 1 and 16 years, was analyzed retrospectively. Analysis of covariance (ANCOVA) was applied to study how sex affects the growth of the ratio Bo/Ca in the boys and girls groups. The regression model, describing age as a linear function of sex and the Bo/Ca ratio for the new Italian sample, yielded the following formula: Age = -1.7702 + 1.0088 g + 14.8166 (Bo/Ca). This model explained 83.5% of total variance (R(2) = 0.835). The median of the absolute values of residuals (observed age minus predicted age) was -0.38, with a quartile deviation of 2.01 and a standard error of estimate of 1.54. A second sample test of 204 Italian children (108 girls and 96 boys), aged between 1 and 16 years, was used to evaluate the accuracy of the specific regression model. A sample paired t-test was used to analyze the mean differences between the skeletal and chronological age. The mean error for girls is 0.00 and the estimated age is slightly underestimated in boys with a mean error of -0.30 years. The standard deviations are 0.70 years for girls and 0.78 years for boys. The obtained results indicate that there is a high relationship between estimated and chronological ages. PMID:26874435

    Background An obesity subphenotype, named ‘metabolically healthy obese’ (MHO) has been recently defined to characterise a subgroup of obese individuals with less risk for cardiometabolic abnormalities. To date no data are available on participants born with small weight for gestational age (SGA) and the risk of metabolically unhealthy obesity (MUHO). Objective Assess the risk of MUHO in SGA versus appropriate for gestational age (AGA) adult participants. Methods 129 young obese individuals (body mass index ≥30 kg/m²) from data of an 8-year follow-up Haguenau cohort (France), were identified out of 1308 participants and were divided into 2 groups: SGA (n=72) and AGA (n=57). Metabolic characteristics were analysed and compared using unpaired t-test. The HOMA-IR index was determined for the population and divided into quartiles. Obese participants within the first 3 quartiles were considered as MHO and those in the fourth quartile as MUHO. Relative risks (RRs) and 95% CI for being MUHO in SGA versus AGA participants were computed. Results The SGA-obese group had a higher risk of MUHO versus the AGA-obese group: RR=1.27 (95% CI 1.10 to 1.6) independently of age and sex. Conclusions In case of obesity, SGA might confer a higher risk of MUHO compared with AGA. PMID:27580829

    Background Extremely preterm birth is associated with subsequent behavioral problems. We hypothesized that perinatal systemic inflammation, a risk factor for cerebral white matter injury and cognitive impairment, is associated with behavior problems observed at 2 years. Methods In a cohort of 600 children born before 28 weeks gestation, we measured 25 inflammation-related proteins in blood collected on postnatal days 1, 7, and 14, and identified behavior problems using parent responses to the Child Behavior Checklist for Ages 1.5–5 (CBCL/1.5-5) at two years of age. A persistent or recurrent protein elevation was defined as a concentration in the highest quartile (for gestational age and postnatal age) on at least two days approximately one week apart. Behavior problems were defined by CBCL/1.5-5 subscale scores at or above the 93rd percentile. Results A single-day elevation of ICAM-3 was associated with an increased risk of an attention problem, as were persistent or recurrent elevations of MPO, IL-6, TNF-RI, IL-8, ICAM-3, VEGF-R1, and VEGF-R2. These associations persisted among infants without white matter injury and cognitive impairment. Conclusion Among children born extremely prematurely, recurrent or persistent elevations of inflammation-related proteins in blood during in the first two postnatal weeks are associated with an attention problem at age 2 years.

    Objectives Small for gestational age (SGA) is considered as an indicator of intrauterine growth restriction, and multiple maternal and newborn characteristics have been identified as risk factors for SGA. This knowledge is mainly based on measures of average association (ie, OR) that quantify differences in average risk between exposed and unexposed groups. Nevertheless, average associations do not assess the discriminatory accuracy of the risk factors (ie, its ability to discriminate the babies who will develop SGA from those that will not). Therefore, applying measures of discriminatory accuracy rather than measures of association only, our study revisits known risk factors of SGA and discusses their role from a public health perspective. Design Cross-sectional study. We measured maternal (ie, smoking, hypertension, age, marital status, education) and delivery (ie, sex, gestational age, birth order) characteristics and performed logistic regression models to estimate both ORs and measures of discriminatory accuracy, like the area under the receiver operating characteristic curve (AU-ROC) and the net reclassification improvement. Setting Data were obtained from the Swedish Medical Birth Registry. Participants Our sample included 731 989 babies born during 1987–1993. Results We replicated the expected associations. For instance, smoking (OR=2.57), having had a previous SGA baby (OR=5.48) and hypertension (OR=4.02) were strongly associated with SGA. However, they show a very small discriminatory accuracy (AU-ROC≈0.5). The discriminatory accuracy increased, but remained unsatisfactorily low (AU-ROC=0.6), when including all variables studied in the same model. Conclusions Traditional risk factors for SGA alone or in combination have a low accuracy for discriminating babies with SGA from those without SGA. A proper understanding of these findings is of fundamental relevance to address future research and to design policymaking recommendations in a more informed

    Objective: To determine the incidence of urinary tract infections (UTIs) in infants and children (4 months to 6 years of age) with febrile diarrhea, as outpatients. Methods: This was a prospective institutional review board–approved study. patients (between 4 months and 6 years of age) were enrolled in the study who presented to the pediatric emergency room with a complaint of fever (rectal temperature 101°F or more) and diarrhea (watery stools >3 in number). The patients were evaluated for state of hydration, and also urine samples were collected. For those children not toilet trained, urine specimens were collected by bladder catheterization, and for those children toilet trained, urine specimens were obtained by midstream collection method. The urine samples obtained were sent for analysis and culture. Results: Eighty patients were enrolled in the study. The number of specimens obtained by clean catch midstream was 20, and by bladder catheterization was 60. None of the urine specimens obtained by both methods of collection grew any organism. There was no increased incidence of infections in male children whether circumcised (10/60) or uncircumcised (50/60). The mean temperature was 102.8°F (range = 101°F to 105°F). Statistics: Using in silico online 2 × 2 χ2 test by comparing both the positive and negative urine culture results, 2-tailed P value is <.0001. Conclusions: Our prospective randomized study concluded that there is no increased incidence of UTIs in infants and children (4 months to 6 years of age) with febrile diarrhea.

    We aimed to present the outcomes of PNL surgery performed in infantile patients with small renal stones who were younger than 1 year of age. A single-center prospective trial was initiated and during the period between Jan 2013 and Jan 2015, PNL was applied to 20 renal units of 16 infants (6 girls and 10 boys), including 4 patients with bilateral kidney stones. PNL was performed in patients with renal stones larger than 2 cm, as well as stones resistant to SWL or renal stones that were undetectable during SWL. The mean age of the patients was 9.55 (5-12) months. Of the 20 renal units, 1 had complete staghorn stones, 3 had partial staghorn stones, 13 had renal pelvic stones, and 3 had lower pole stones. The mean stone size was 18.5 mm (range 12-36 mm). Mean operative time for PNL was 88 (25-135 min). Mean fluoroscopy time was estimated as 3.4 min. Mean hemoglobin loss was 0.72 g/L (0.2-3). The mean hospital stay was 4.1 days (2-8 days). On postoperative day 1, a complete stone-free state was achieved in 70% of renal units (14 of 20). At the end of the first postoperative week, the remaining two patients had insignificant residual fragments of 3 mm and were followed conservatively without any specific intervention. Thus, the total SFR was 80% (16 of 20) at discharge. In infants aged less than 1 year, minimal access tract dilation during PNL, the use of smaller caliber pediatric instruments, and the realization of this procedure by surgeons with adequate experience in adults carry utmost importance. In addition, special care should be taken to avoid hypothermia and radiation exposure during PNL.

    A double-blind, randomized, placebo-controlled trial was conducted from March 2001 to March 2002 involving 309 infants who received either a processed complementary food (CF) or an unprocessed placebo from 6 to 12 mo of age. The groups were comparable in baseline characteristics. The study took place in Kilosa district, Tanzania. The processed CF contained germinated, autoclaved, and dried finger millet (65.2%), kidney beans (19.1%), roasted-peanuts (8%), and mango purée (7.7%). The same blend, but not processed, served as the placebo. Processing increased iron solubility and energy density without affecting viscosity. Mean length for age, weight for age, hemoglobin, and zinc protoporphyrin at 6 and 12 mo did not differ between the 2 groups. The results show that the processed food did not differ from the unprocessed placebo in improving growth, hemoglobin, and iron status of infants when given under the study conditions. The control group consumed equal amounts of macronutrients, and the higher energy density in this study did not seem to have any benefits. In our study, there was a very intensive follow-up; at every encounter with mothers, giving the required amounts and adding extra lipids was strongly reinforced. Under those conditions, a well-balanced complementary food with additional lipids can meet the energy needs of young children. The reduction in phytates by 34% and improvement in iron solubility to 19% due to processing might not have been enough to compensate for the rather low iron content of the complementary food.

    We aimed to present the outcomes of PNL surgery performed in infantile patients with small renal stones who were younger than 1 year of age. A single-center prospective trial was initiated and during the period between Jan 2013 and Jan 2015, PNL was applied to 20 renal units of 16 infants (6 girls and 10 boys), including 4 patients with bilateral kidney stones. PNL was performed in patients with renal stones larger than 2 cm, as well as stones resistant to SWL or renal stones that were undetectable during SWL. The mean age of the patients was 9.55 (5-12) months. Of the 20 renal units, 1 had complete staghorn stones, 3 had partial staghorn stones, 13 had renal pelvic stones, and 3 had lower pole stones. The mean stone size was 18.5 mm (range 12-36 mm). Mean operative time for PNL was 88 (25-135 min). Mean fluoroscopy time was estimated as 3.4 min. Mean hemoglobin loss was 0.72 g/L (0.2-3). The mean hospital stay was 4.1 days (2-8 days). On postoperative day 1, a complete stone-free state was achieved in 70% of renal units (14 of 20). At the end of the first postoperative week, the remaining two patients had insignificant residual fragments of 3 mm and were followed conservatively without any specific intervention. Thus, the total SFR was 80% (16 of 20) at discharge. In infants aged less than 1 year, minimal access tract dilation during PNL, the use of smaller caliber pediatric instruments, and the realization of this procedure by surgeons with adequate experience in adults carry utmost importance. In addition, special care should be taken to avoid hypothermia and radiation exposure during PNL. PMID:26002160

    We sought to evaluate the oral health status of children born small for gestational age (SGA). Children now aged 4-8 years who were born SGA (birth weight < -2 SDS) were examined using standardised criteria. The parents completed a structured oral health questionnaire. Twenty females and 25 males, mean age 72.1 months, and mean birth weight 2.1 kg, participated in the study. Poor appetite was a concern; 32 (71%) children snacked between meals and 14 (30%) used carbonated beverages more than 3 times daily. Erosion was present in 9 (20%) children. Dental decay occurred in 22 (47%) children with 92% being untreated. Eight children had more than 5 decayed teeth. It is essential that clinicians working with children born SGA include oral health within the general health surveillance and refer these children for a dental assessment within the first 2 years to support parents in establishing safe feeding patterns for their children.

    The quality of maternal-infant interaction is a critical factor in the development of infants' autonomic function and social engagement skills. In this secondary data analysis, relationships among infant and maternal affect and behavior and quality of dyadic interaction, as measured by the Parent-Child Early Relational Assessment, and infant autonomic function, as measured by heart rate variability, were examined during feeding at 2 weeks and 2 months of age in 16 healthy infants and in 15 infants with transposition of the great arteries (TGA). Contrary to previous research, at 2 weeks infant age, mothers of infants with TGA had significantly higher scores in affect and behavior than did mothers of healthy infants. The affect and behavior and quality of dyadic interaction of infants with TGA also did not differ from that of healthy infants. Although infants' social engagement skills did not differ by health condition (TGA or healthy), these skills did differ by parasympathetic nervous system function: infants better able to suppress vagal activity with challenge had more positive and less dysregulated affect and behavior, regardless of health status. These findings suggest that maternal-infant interactions for some cardiac disease subgroups may not differ from healthy dyads. Additional research is required to identify both healthy and ill infants with delayed autonomic maturation and to develop and test interventions to enhance critical interactive functions.

    Aims: To assess growth and factors associated with growth in children born small for gestational age (SGA) from two socioeconomic strata in comparison to age- and sex-matched healthy controls. Methods: Retrospective study conducted at two hospitals in Pune, 0.5–5 years, 618 children: 189-SGA from upper socioeconomic strata (USS), 217-SGA from lower socioeconomic strata (LSS), and 212 appropriate for gestational age healthy controls were randomly selected. Birth and maternal history, socioeconomic status, length/height, and weight of children were recorded. Anthropometric data were converted to Z scores (height for age Z-score [HAZ], weight for age Z-score [WAZ]) using WHO AnthroPlus software. Results: The HAZ and WAZ of the SGA group were significantly lower as compared to the controls and that of the LSS SGAs were lower than USS SGAs (P < 0.05). Thirty two percent children were stunted (HAZ <−2.0) in USS and 49% in LSS (P < 0.05). Twenty nine percent children in the USS SGA group were stunted at 2 years and 17% at 5 years. In the LSS SGA group, 54% children were stunted at 2 years and 46% at 5 years. Generalized linear model revealed normal vaginal delivery (β = 0.625) and mother's age (β =0.072) were positively associated and high SES (β = −0.830), absence of major illness (β = −1.01), higher birth weight (β = −1.34) were negatively associated for risk of stunting (P < 0.05). Conclusion: Children born SGA showed poor growth as compared to controls. Special attention to growth is necessary in children from LSS, very low birth weight babies, and those with major illnesses during early years of life. PMID:27366721

    Infant botulism is a paralytic syndrome which manifests as a result of ingesting spores of the toxin secreting bacterium Clostridium botulinum by infants. As opposed to botulism in adults, treating infant botulism with horse antiserum was not approved due to several safety issues. This restriction has led to the development of Human Botulism Immune Globulin Intravenous (BIG-IV; sells under BabyBIG). In this article we review infant botulism and the advantages of treating it with BIG-IV.

    Objectives Undernutrition during early life contributes to more than 200 million children globally not fulfilling their developmental potential. Our objective was to determine whether dietary supplementation with several formulations of lipid-based nutrient supplements (LNS), which differed in dose per day and milk content, positively affect infant development in Malawi. Methods We randomly assigned 1932 infants age 6 months to receive one of the following for 12 months: 10, 20 g, or 40 g/day milk-containing LNS, 20 g or 40 g/day milk-free LNS, or no supplement until 18 months of age (control group). We assessed motor, language, socio-emotional, and executive function at age 18 months. Primary analysis was by intention-to-treat and we also examined 13 potential effect modifiers, including the child's initial nutritional status and level of developmental stimulation. The study is registered as clinical trial NCT00945698. Results We found no significant differences between intervention groups in any scores. The difference in mean z-scores between children in the control group and children in the intervention groups ranged from -0.08 to 0.04 for motor development (p = 0.76), -0.05 to 0.01 for language development (p = 0.97), -0.15 to 0.11 for socio-emotional development (p = 0.22), and -0.02 to 0.20 for executive function (p = 0.24). We did not find that initial nutritional status, developmental stimulation, or other factors modified the effect LNS versus control group. Conclusions for Practice Our results suggest that in a population such as this one, provision of LNS from age 6 to 18 months would not affect motor, language, socio-emotional, or executive function skills at age 18 months.

    Childhood obesity is associated with many adverse health effects during childhood and is linked to an increased risk for obesity in adulthood. The objective of this study was to determine the characteristics of early childhood overweight and obesity and assess the impact of breastfeeding. Data from Hawai'i's Special Supplemental Nutrition Program for Women, Infants and Children (WIC) were analyzed for children 2 years of age born between 2005 and 2009 and their mothers. Childhood overweight and obesity was examined using a log-binomial regression model to estimate prevalence ratios. In the sample population, 12.5 % of children were overweight and 8.5 % of children were obese. Significant differences in childhood overweight and obesity were seen between breastfeeding duration and other socio-demographic groups. Children who were breastfed for 6 months or more had a lower risk of childhood obesity at age two compared to those who were never breastfed (APR 0.79, 95 % CI 0.69-0.91) with adjustment for child race/ethnicity, maternal age, trimester of prenatal care entry, maternal smoking status, and child birth weight. The prevalence of early childhood overweight and obesity is associated with shorter durations of breastfeeding. Early and continued breastfeeding support and education for mothers in the WIC program that improves duration of breastfeeding may help reduce the risk of early childhood obesity.

    2013-01-01

    Summary Vitamin D has well-defined classical functions related to calcium metabolism and bone health but also has non-classical effects that may influence other aspects of health. There has been considerable recent interest in the role of vitamin D on outcomes related to pregnancy and young child health but few efforts have been made to systematically consolidate this evidence to inform the research and policy agenda for low income countries. A systematic review was undertaken to identify intervention and observational studies of vitamin D supplementation, intake, or status (25-hydroxy-vitamin D) during pregnancy on perinatal and infant health outcomes. Data from trials and observational studies isolating the effect of vitamin D supplementation and intake were extracted and study quality was evaluated. Meta-analysis was used to pool effect estimates. We identified 5 randomized trials with outcomes of relevance to our review. All had small sample size and dosage amount, duration, and frequency varied as did the ability to correct deficiency. Pooled analysis of trials using fixed effects models suggested protective effects of supplementation on low birthweight (3 trials, Risk ratio (RR)=0.40 [95% confidence interval (CI), 0.23, 0.71]) and non-significant but suggestive effects of daily supplementation on small-for-gestational age (SGA) (2 trials, RR=0.67, [0.40, 1.11]. No effect on preterm delivery (<37 weeks) was evident (2 trials, RR=0.77 [0.35, 1.66]). Little evidence from trials exists to evaluate the effect of vitamin D supplementation during pregnancy on maternal, perinatal or infant health outcomes. Based on both trials and observational studies, we recommend that future research explore SGA, preterm delivery, pre-eclampsia, and maternal and childhood infections, as outcomes of interest. Trials should focus on populations with a high prevalence of vitamin D deficiency, explore the relevance of timing of supplementation, and the dosage used in such trials

    Background: Early auditory and speech development in home-based early intervention of infants and toddlers with hearing loss younger than 2 years are still spare in China. This study aimed to observe the development of auditory and speech in deaf infants and toddlers who were fitted with hearing aids and/or received cochlear implantation between the chronological ages of 7–24 months, and analyze the effect of chronological age and recovery time on auditory and speech development in the course of home-based early intervention. Methods: This longitudinal study included 55 hearing impaired children with severe and profound binaural deafness, who were divided into Group A (7–12 months), Group B (13–18 months) and Group C (19–24 months) based on the chronological age. Categories auditory performance (CAP) and speech intelligibility rating scale (SIR) were used to evaluate auditory and speech development at baseline and 3, 6, 9, 12, 18, and 24 months of habilitation. Descriptive statistics were used to describe demographic features and were analyzed by repeated measures analysis of variance. Results: With 24 months of hearing intervention, 78% of the patients were able to understand common phrases and conversation without lip-reading, 96% of the patients were intelligible to a listener. In three groups, children showed the rapid growth of trend features in each period of habilitation. CAP and SIR scores have developed rapidly within 24 months after fitted auxiliary device in Group A, which performed much better auditory and speech abilities than Group B (P < 0.05) and Group C (P < 0.05). Group B achieved better results than Group C, whereas no significant differences were observed between Group B and Group C (P > 0.05). Conclusions: The data suggested the early hearing intervention and home-based habilitation benefit auditory and speech development. Chronological age and recovery time may be major factors for aural verbal outcomes in hearing impaired children

    This longitudinal study reported the mid- and long-term neurodevelopmental outcome of 166 premature infants born with an extremely low birth weight (<1,000 g), all small for gestational age (<10th percentile birth weight for gestational age). Nine girls were lost to follow-up before 3 years of age, and 6 children were excluded a posteriori because of specific conditions diagnosed in the 1st year of life (severe abnormalities in 5). Of the remaining 151 children, 2% had cerebral palsy, 15% had lesser motor disturbances (reduced to 2% after psychomotor training), 8% had early severe developmental delays, and added mild and moderate delays and increasing cognitive gaps amounted to 28% in the 14th year. Visual deficits increased with age up to 63% of the older children. Seven children had deafness and 13 had hearing losses after otitis media. Language delays were observed at some stage in 31% of cases, as well as behavioral disturbances in 42% (severe problems in 12%). At last evaluation, 34% of the children were normal (12% of the older ones), 51% had minor deficiencies, 18% had moderate and 3% had major disabilities. Children entered the first grade in the 7th year in only 84% of cases, which dropped to 63% at proper level in the second grade; 47% entered high school at the proper age, 7/15 obtained the 'baccalauréat' in the 19th/20th year. The school performance was heavily dependent on the socioeconomic and cultural level of the family. PMID:12011568

    Our study was developed to ascertain reference ranges of 11-dehydrothromboxane B2 (11-dhTXB2) in the urine of healthy pediatric subjects. Urine samples were analyzed using the AspirinWorks™ assay that measures levels of 11-dehydrothromboxane B2. 128 individuals (2 months to 18 years) were identified as healthy and not receiving aspirin. When adjusted as picograms/milligrams urine creatinine, there was a negative correlation between age and level of 11-dehydrothromboxane B2 (P = 0.0001). This study confirms a negative correlation between age and level of urinary 11-dehydrothromboxane B2 and provides a set of age-specific reference ranges.

    The skin of preterm infants varies considerably in its level of maturity. To understand skin absorption in premature infants better, we report a technique for the assessment of percutaneous absorption at various gestational and postnatal ages using stable, isotope-labeled (13C6) benzoic acid. Our results indicate that in the preterm infant, this method detects enhanced skin absorption in the first postnatal days, which declines over three weeks to that expected of a full-term infant. This approach also indicates an inverse relationship between gestational age and skin absorption, as well as postnatal age and skin absorption. The reported technique is a safe and noninvasive method using a model skin penetrant for the study of percutaneous absorption in preterm infants from which basic data may be derived to add to our understanding of skin barrier function.

    The current study explores the effects of exposure to maternal voice on infant sucking in preterm infants. Twenty-four preterm infants averaging 35 weeks gestational age were divided randomly into two groups. A contingency between high-amplitude sucking and presentation of maternal voice was instituted for one group while the other group served as a yoked control. No significant differences were observed in sucking of the two groups, but the degree of pitch modulation of the maternal voice predicted an increase in the rate of infant sucking.

  3. Latin American Consensus: Children Born Small for Gestational Age

    PubMed Central

    2011-01-01

    Background Children born small for gestational age (SGA) experience higher rates of morbidity and mortality than those born appropriate for gestational age. In Latin America, identification and optimal management of children born SGA is a critical issue. Leading experts in pediatric endocrinology throughout Latin America established working groups in order to discuss key challenges regarding the evaluation and management of children born SGA and ultimately develop a consensus statement. Discussion SGA is defined as a birth weight and/or birth length greater than 2 standard deviations (SD) below the population reference mean for gestational age. SGA refers to body size and implies length-weight reference data in a geographical population whose ethnicity is known and specific to this group. Ideally, each country/region within Latin America should establish its own standards and make relevant updates. SGA children should be evaluated with standardized measures by trained personnel every 3 months during year 1 and every 6 months during year 2. Those without catch-up growth within the first 6 months of life need further evaluation, as do children whose weight is ≤ -2 SD at age 2 years. Growth hormone treatment can begin in SGA children > 2 years with short stature (< -2.0 SD) and a growth velocity < 25th percentile for their age, and should continue until final height (a growth velocity below 2 cm/year or a bone age of > 14 years for girls and > 16 years for boys) is reached. Blood glucose, thyroid function, HbA1c, and insulin-like growth factor-1 (IGF-1) should be monitored once a year. Monitoring insulin changes from baseline and surrogates of insulin sensitivity is essential. Reduced fetal growth followed by excessive postnatal catch-up in height, and particularly in weight, should be closely monitored. In both sexes, gonadal function should be monitored especially during puberty. Summary Children born SGA should be carefully followed by a multidisciplinary group

    Introduction The human placenta expresses the IGF-I and IGF-IR proteins and their intracellular signal components (IRS-1, AKT and mTOR). The aim of this study was to assess the IGF-IR content and activation of downstream signaling molecules in placentas from newborns who were classified by gestational age and birth weight. We studied placentas from 25 term appropriate (T-AGA), 26 term small (T-SGA), 22 preterm AGA (PT-AGA), and 20 preterm SGA (PT-SGA) newborns. The total and phosphorylated IGF-IR, IRS-1, AKT, and mTOR contents were determined by Western Blot and normalized by actin or with their respective total content. The effect of IGF-I was determined by stimulating placental explants with recombinant IGF-I 10-8 mol/L for 15, 30, and 60 minutes. Results The IGF-IR content was higher in T-SGA compared to T-AGA placentas, and the IRS-1 content was higher in PT-placentas compared with their respective T-placentas. The effect of IGF-I on the phosphorylated forms of IGF-IR was increased in T-SGA (150%) and PT-SGA (300%) compared with their respective AGA placentas. In addition, AKT serine phosphorylation was higher in PT-SGA compared to PT-AGA and T-SGA placentas (90% and 390% respectively). Conclusion The higher protein content and response to IGF-I of IGF-IR, IRS-1, and AKT observed in SGA placentas may represent a compensatory mechanism in response to fetal growth restriction.

    Exposure to maternal depression increases risks for altered mother-infant interactions. Serotonin reuptake inhibitor (SRI) antidepressants are increasingly prescribed to manage antenatal maternal illness. The impact of SRIs on early mother-infant interactions was unknown. Three-month-old infants of 32 depressed mothers treated with SRI medications during pregnancy and 43 non-medicated mothers were studied. Using an established face-to-face mother-infant interaction paradigm, dyad interactions were studied with and without a toy. Videotaped sessions yielded 4 measures: maternal sensitivity, dyadic organization, infant readiness to interact, and maternal interruptive behaviors. Even with prenatal SRI treatment, depressed mothers interrupted their infants more during toy play. In the absence of prenatal SRI treatment, maternal postnatal depression adversely influenced infant behavior. Higher levels of maternal depression symptoms at 3 months predicted poorer infant readiness to interact during the toy session. Conversely, in the SRI-exposed group, higher prenatal depression scores predicted greater infant readiness to interact at 3 months. Increased infant readiness with SRI exposure suggests a "fetal programming effect" whereby prenatal maternal mood disturbances shaped a future response to a postnatal depressed maternal environment.

    2013-01-01

    Background Small-for-gestational age (SGA) newborns constitute a special group of neonates who may have suffered varying degrees of intrauterine insults and deprivation. Variations in birth weight, length and Ponderal Index (PI) depend on the type and degree of intrauterine insults the babies were exposed to. The objective of the study was to determine the current prevalence of term SGA births in a Nigerian Tertiary Hospital and the current pattern of Ponderal Indices among term SGA in a population of Nigerian babies. Methods Subjects comprised of consecutive term singleton mother-baby pairs in the first 24 hours of life. It was a cross sectional study. The anthropometric parameters of each baby were recorded and the PI was also determined. Results Out of 1,052 live births during the study period (September to December, 2009), 825 were term, singleton babies. Five hundred and eight-one babies (70.4%) fall into the upper socio-economic classes 1 and II, 193 (23.4%) in the middle class and 51 (6.2%) were of the lower classes IV and V. None of the mothers indicated ingestion of alcohol or smoking of cigarette. Fifty-nine babies (7.2%) were small-for gestational age (SGA). Of the 59 SGA subjects, 26 (44.1%) were symmetrical SGA while 33 (55.9%) were asymmetrical SGA. There was no significant sex or socioeconomic predilection for either symmetrical or asymmetrical growth (p = 0.59, 0.73 respectively). Conclusion The findings showed that proportionality in SGA fetuses is a continuum, with the PI depending on the duration of intrauterine insult and the extent of its effects on weight and length before delivery.

    Maternal nutrition is recognized as one of the determinants of fetal growth. Consumption of fruits and vegetables is promoted as part of a healthful diet; however, intakes are typically lower than recommended levels. The purpose of this study was to systematically review results from studies examining the relationship between maternal consumption of fruits and vegetables during pregnancy with infant birth weight or risk for delivering a small for gestational age baby. A comprehensive search of PubMed and EMBASE was conducted and abstracts were screened using predefined criteria. Eleven relevant studies were identified and systematically reviewed, including six prospective cohort studies, three retrospective cohort studies, and two case–control studies. Seven studies were conducted in cohorts from highly developed countries. One prospective study from a highly developed area reported increased risk for small for gestational age birth by women with low vegetable intakes (odds ratio 3.1; 95% confidence interval 1.4–6.9; P=0.01); another large prospective study reported a 10.4 g increase in birth weight per quintile increase in fruit intake (95% confidence interval 6.9–3.9; P<0.0001) and increases of 8.4 or 7.7 g per quintile intake of fruits and vegetables (combined) or fruits, vegetables, and juice (combined), respectively. One retrospective study reported an association between low fruit intake and birth weight. In less developed countries, increased vegetable or fruit intake was associated with increased birth weight in two prospective studies. Overall, limited inconclusive evidence of a protective effect of increased consumption of vegetables and risk for small for gestational age birth, and increased consumption of fruits and vegetables and increased birth weight among women from highly developed countries was identified. Among women in less developed countries, limited inconclusive evidence suggests that increased consumption of vegetables or fruits may be

    Cognitive development might be influenced by parenting practices and child temperament. We examined whether the associations between parental warmth, control and intelligence quotient (IQ) may be heightened among children in difficult temperament. Participants were from the Avon Longitudinal Study of Parents and Children (n = 7,044). Temperament at 6 months was measured using the Revised Infant Temperament Questionnaire and classified into 'easy' and 'difficult'. Parental warmth and control was measured at 24 to 47 months and both were classified into 2 groups using latent class analyses. IQ was measured at 8 years using the Wechsler Intelligence Scale for Children and dichotomized (<85 and ≥85) for analyzing effect-measure modification by temperament. Linear regression adjusted for multiple confounders and temperament showed lower parental warmth was weakly associated with lower IQ score [β = -0.52 (95% CI 1.26, 0.21)], and higher parental control was associated with lower IQ score [β = -2.21 (-2.95, -1.48)]. Stratification by temperament showed no increased risk of having low IQ in temperamentally difficult children [risk ratio (RR) = 0.97 95% CI 0.65, 1.45)] but an increased risk among temperamentally easy children (RR = 1.12 95% CI 0.95, 1.32) when parental warmth was low. There was also no increased risk of having low IQ in temperamentally difficult children (RR = 1.02 95% CI 0.69, 1.53) but there was an increased risk among temperamentally easy children (RR = 1.30 95% CI 1.11, 1.53) when parental control was high. For both parental warmth and control, there was some evidence of negative effect-measure modification by temperament on the risk-difference scale and the risk-ratio scale. It may be more appropriate to provide parenting interventions as a universal program rather than targeting children with difficult temperament. PMID:27027637

    Objective To describe the development and evaluation of an observation system to assess the process of mother-infant feeding interaction relevant to infant neuro-behavioral regulation: the Mother-Infant Feeding Tool. Design Secondary analysis. Setting Special care nursery just before discharge and in the home at 1 and 4 months postterm age. Participants Forty-three mother-infant dyads. Methods Videotaped feeding interactions were examined to assess regulatory processes of mother-infant interaction. Data were collected at three times over the infant’s first 4 postterm months: before the infant’s discharge from the special care nursery and at 1 and 4 months postterm age in the home. Results Across all three data points mothers rarely talked to their infants. Conclusion Further testing is needed, but the Mother-Infant Feeding Tool shows promise in assessing very early mother-infant feeding interactions. PMID:19614885

    DiLalla, L F; Bishop, E G

    1996-11-01

    This project utilized twins to study differential mother-sibling interactions. The use of twins circumvented the traditional confounds of studying siblings of different ages or at two points in time. When the twins were 7 and 9 months of age, mothers spent 2.5 min alone with each infant in an attempt to elicit child vocalizations. The mother and infant behaviors were coded both microanalytically and globally. The infant attention behaviors were influenced primarily by unique environment, whereas the temperament behaviors were influenced by both unique environmental and genetic effects. Mothers tended to treat both children similarly, regardless of zygosity, suggesting that maternal characteristics drove the mother-infant interactions. Thus, even though identical twins were more similar on some measures than fraternal twins, mothers tended to treat both types of twins comparably regardless of infant characteristics or behaviors.

    Background Near-infrared spectroscopy (NIRS) monitoring of cerebral oxygen saturation (rSO2) has become routine in many centers, but no studies have reported the relationship of intraoperative NIRS to long-term neurodevelopmental outcomes after cardiac surgery. Methods and Results Of 104 infants undergoing biventricular repair without aortic arch reconstruction, 89 (86%) returned for neurodevelopmental testing at age 1 year. The primary NIRS variable was the integrated rSO2 (area under the curve) for rSO2 ≤ 45%; secondary variables were the average and minimum rSO2 by perfusion phase and at specific time points. Psychomotor (PDI) and Mental Development Indexes of the Bayley Scales, head circumference, neurologic examination, and abnormalities on brain MRI did not differ between subjects according to a threshold level for rSO2 of 45%. Lower PDI scores were modestly associated with lower average (r=0.23; P=0.03) and minimum rSO2 (r=0.22; P=0.04) during the 60 minute period following cardiopulmonary bypass (CPB), but not with other perfusion phases. Hemosiderin foci on brain MRI were associated with lower average rSO2 from post-induction to 60 minutes post-CPB (71±10 vs. 78±6%; P=0.01), and lower average rSO2 during the rewarming phase (72±12 vs. 83±9%; P=0.003) and during the 60 minute period following CPB (65±11 vs. 75±10%; P=0.009). In regression analyses adjusting for age ≤ 30 days, PDI score (P=0.02) and brain hemosiderin (P=0.04) remained significantly associated with rSO2 during the 60 minute period following CPB. Conclusions Perioperative periods of diminished cerebral oxygen delivery, as indicated by rSO2, are associated with one-year PDI and brain MRI abnormalities among infants undergoing reparative heart surgery.

    Abstract Recurrent wheezing (RW) has a significant impact on infants, caregivers, and society, but morbidity and related medical resource utilization (MRU) have not been thoroughly explored. The burden of RW needs to be documented with population-based data. The objective was to assess the characteristics, medical management, and MRU of RW infants identified from national claims data. Infants aged from 6 to 24 months, receiving ≥2 dispensations of respiratory drugs within 3 months, and presenting a marker of poor control (index date), were selected. During the 6 months after index date, MRU was described in the cohort and among 3 subgroups with more severe RW, defined as ≥4 dispensations of respiratory drugs, ≥3 dispensations of oral corticosteroids (OCS), or ≥1 hospitalization for respiratory symptoms. A total of 115,489 infants had RW, corresponding to 8.2% of subjects in this age group. During follow-up, 68.7% of infants received inhaled corticosteroids, but only 1.8 U (unit) were dispensed over 6 months, suggesting discontinuous use. Control was mostly inadequate: 61.7% of subjects received OCS, 80.2% antibiotics, and 71.2% short-acting beta-agonists, and medical/paramedical visits were numerous, particularly for physiotherapy. Severe RW concerned 39.0% of the cohort; 32.8% and 11.7% of infants had repeated use of respiratory drugs and OCS, respectively, and 5.5% were hospitalized for respiratory symptoms. In this real-life nation-wide study, RW was common and infants had poor control and high MRU. Interventions are needed to support adequate use of controller therapy, and to improve medical care.

    Objective. Small for gestational age (SGA) is associated with increased neonatal morbidity and mortality. At present, evidence on whether these pregnancies should be managed expectantly or by induction is lacking. To get insight in current policy we analysed data of the National Dutch Perinatal Registry (PRN). Methods. We used data of all nulliparae between 2000 and 2005 with a singleton in cephalic presentation beyond 36+0 weeks, with a birth weight below the 10th percentile. We analysed two groups of pregnancies: (I) with isolated SGA and (II) with both SGA and hypertensive disorders. Onset of labour was related to route of delivery and neonatal outcome. Results. Induction was associated with a higher risk of emergency caesarean section (CS), without improvement in neonatal outcome. For women with isolated SGA the relative risk of emergency CS after induction was 2.3 (95% Confidence Interval [CI] 2.1 to 2.5) and for women with both SGA and hypertensive disorders the relative risk was 2.7 (95% CI 2.3 to 3.1). Conclusion. Induction in pregnancies complicated by SGA at term is associated with a higher risk of instrumental deliveries without improvement of neonatal outcome. Prospective studies are needed to determine the best strategy in suspected IUGR at term. PMID:21490789

    Aim Toll-like receptors (TLR) play a crucial role in innate immunity, protecting the host from pathogens such as viruses. Genetic variations in TLRs have been associated with the severity of viral bronchiolitis in infancy and with the later occurrence of post-bronchiolitis asthma. The aim of the present study was to evaluate if there are any exploratory associations between TLR gene polymorphisms and lung function at 5 to 7 years of age in former bronchiolitis patients. Methods We performed impulse oscillometry (IOS) at the median age of 6.3 years for 103 children who had been hospitalized for bronchiolitis at less than six months of age. The main parameters evaluated were airway resistance and reactance at 5Hz in baseline and post-exercise measurements. Data on single nucleotide polymorphisms (SNP) of TLR1 rs5743618, TLR2 rs5743708, TLR6 rs5743810 and TLR10 rs4129009 (TLR2 subfamily) and TLR3 rs3775291, TLR4 rs4986790, TLR7 rs179008, TLR8 rs2407992 and TLR 9 rs187084 were available for analyses. Results The TLR4 rs4986790 wild genotype A/A was associated with a greater Rrs5 response (0.72 vs. -0.42, p = 0.03) to exercise. In TLR6 rs5743810, the minor allele T was associated with greater Rrs5 response (0.80 vs. -0.03, p = 0.04) to exercise. In TLR7 rs179008, the major allele A was associated with baseline decline in dRrs/df (-1.03 vs 0.61, p = 0.01) and increased Fres (2.28 vs. 0.89, p = 0.01) in girls. Conclusion Among the nine studied TLRs, only TLR7 rs179008 showed some exploratory associations with post-bronchiolitis lung function deficiency, and polymorphisms of TLR4 rs4986790, and TLR6 rs5743810 in particular, with airway reactivity. These findings call for further confirmatory studies. PMID:26741133

    2016-02-01

    ITSEA is an often recommended tool for assessment of social-emotional problems and competence delays in children aged 12-36 months, but concerns have been raised about low variability and age-inappropriate questions for children as young as 12 months. This study explored ITSEA's (1) psychometric properties, (2) properties concerning the detection of clinically significant problems and competence delays and (3) discriminant validity at 12 months. A total of 102 children with high versus low risk scores on marker measures of developmental status and parenting stress obtained at 6 months, were selected from a longitudinal population-based study to participate in the present study. Risk status was operationalized as Bayley III Screening Test (Bayley, 2005a. Bayley scales of infant and toddler development: Screening test manual (3rd ed.). San Antonio, TX: Pearson) Composite Subscale scores and Parenting Stress Index total score (PSI, 3rd edition, Abidin, 1995. Parenting Stress Index. Professional manual. (3rd ed.). Odessa, FL: Psychological Assessment Resources). At 12 months, ITSEA was administered to parents as a structured interview to identify guidance needs and to collect qualitative information about the items, and the assessment of developmental level and parenting stress was repeated. All ITSEA domains and subscales were found to be relevant. However, nearly all respondents needed guidance. Moreover, there were substantial floor/ceiling effects on subscale level and one item had to be discarded. ITSEA was used in combination with the Bayley-III Screener and PSI to detect cases with clinically significant scores, with ITSEA making a unique contribution to case detection. Dysregulation problems were the most frequently detected, and the differences between high-risk and low-risk group children and gender differences indicated adequate discriminant validity. The results suggest that ITSEA may be meaningfully applied even among children as young as 12 months. PMID

    Tinea capitis is a reasonably common infection among the pediatric population; however, it is still a relatively rare entity among infants less than one year of age. As such, a high index of suspicion is necessary for diagnosis among infants and an appropriate diagnostic work up should be employed in any case where a dermatophyte infection is suspected. Several methods are available for diagnosis. In addition, proper identification of the specific dermatophyte genera involved should be considered as treatment options may be altered based on the causative pathogen identified. PMID:22468173

    The purpose of this study was to examine changes in prelinguistic vocal productions during the first 20 months of life. Vocalizations were classified into 23 mutually exclusive and exhaustive types, and grouped into five ascending levels using the Stark Assessment of Early Vocal Development-Revised (SAEVD-R). Data from 30 typically developing infants, aged 0–20 months, show that older infants attained higher developmental levels on the SAEVD-R than younger infants. Infants 0–2, 3–5, and 6–8 months of age primarily produced vocalizations from Levels 1 (Reflexive), 2 (Control of Phonation), and 3 (Expansion). Infants 9–20 months of age also produced vocalizations from Level 4 (Basic Canonical Syllables). Only infants from 16–20 months of age produced Level 5 (Advanced Forms) vocalizations in significant quantities. The outcomes indicate that the SAEVD-R is a valuable instrument for evaluating prelinguistic vocal development. PMID:16728333

    Vaccination against measles, mumps, rubella and varicella (MMRV) is currently recommended in developed countries for infants from 12 months of age. However, measles vaccination at 9 months of age is recommended by the WHO in the Expanded Program on Immunization (EPI) schedule and it is therefore possible that MMR or MMRV vaccines might also be given at this age. This open-label, randomised, comparative study evaluated the immunogenicity and safety of a 2-dose schedule of ProQuad(®) (MMRV vaccine) given at a 3-month interval in healthy infants aged ≥9 months. For measles, the non-inferiority of the response rate post-Dose 2 was reached when Dose 1 was administered at 11 months (98%) compared with 12 months (99%) but was not reached when Dose 1 was administered at 9 months (95%). The response rate to measles post-Dose 1 increased with age, from 73% to 88% and 90% at 9, 11 and 12 months, respectively. For mumps, rubella and varicella, response rates were not different after Dose 1 (>95%) or Dose 2 (>99%) regardless of whether Dose 1 was administered at 9, 11 or 12 months of age. In conclusion, the age of administration of the first of a two-dose regimen of ProQuad may be lowered to 11 months. Dose 1 may be administered at 9 months if early protection is required, but it should be recognised that a second dose is required promptly with a minimum of 3-month interval between doses.

    Objective To examine the use and safety of rifampin in hospitalized infants. Study Design Observational study of clinical and laboratory adverse events among infants exposed to rifampin from 348 neonatal intensive care units managed by the Pediatrix Medical Group between 1997 and 2012. Result 2500 infants received 4279 courses of rifampin; mean gestational age was 27 weeks (5th, 95th %tile; 23, 36) and mean birth weight was 1125 g (515, 2830). Thrombocytopenia (121/1000 infant days) and conjugated hyperbilirubinemia (25/1000 infant days) were the most common laboratory adverse events. The most common clinical adverse events were medical necrotizing enterocolitis (64/2500 infants, 3%) and seizure (60/2500 infants, 2%). Conclusion The overall incidence of adverse events among infants receiving rifampin appears low; however, additional studies to further evaluate safety and dosing of rifampin in this population are needed.

    Auditory brainstem response (ABR) audiometry was performed on 76 non-selected premature infants from 32 to 40 weeks conceptional age. Follow-up ABR was completed on 45 infants at 4 months of age. The results were compared to data from selected, relatively low risk infants of comparable age. No significant differences were seen between the two groups, which indicates that normative data from non-selected premature infants can be obtained to identify ABR abnormality.

    Wharton's jelly-derived Mesenchymal Stem Cells (MSCs) isolated from newborns with intrauterine fetal growth restriction were previously shown to exert anabolic features including insulin hypersensitivity. Here, we extend these observations and demonstrate that MSCs from small for gestational age (SGA) individuals have decreased mitochondrial oxygen consumption rates. Comparing normally grown and SGA MSCs using next generation sequencing studies, we measured global transcriptomic and epigenetic profiles and identified E2F1 as an over-expressed transcription factor regulating oxidative metabolism in the SGA group. We further show that E2F1 regulates the differential transcriptome found in SGA derived MSCs and is associated with the activating histone marks H3K27ac and H3K4me3. One of the key genes regulated by E2F1 was found to be the fatty acid elongase ELOVL2, a gene involved in the endogenous synthesis of docosahexaenoic acid (DHA). Finally, we shed light on how the E2F1-ELOVL2 pathway may alter oxidative respiration in the SGA condition by contributing to the maintenance of cellular metabolic homeostasis. PMID:27631473

Finally, we shed light on how the E2F1-ELOVL2 pathway may alter oxidative respiration in the SGA condition by contributing to the maintenance of cellular metabolic homeostasis. PMID:27631473

  15. Do infants influence their quality of care? Infants' communicative gestures predict caregivers' responsiveness.

    Infants' effects on adults are a little studied but important aspect of development. What do infants do that increases caregiver responsiveness in childcare environments? Infants' communicative behaviors (i.e. smiling, crying) affect mothers' responsiveness; and preschool children's language abilities affect teachers' responses in the classroom setting. However, the effects of infants' intentional communications on either parents' or non-parental caregivers' responsiveness have not been examined. Using longitudinal video data from an infant classroom where infant signing was used along with conventional gestures (i.e. pointing), this study examines whether infants' use of gestures and signs elicited greater responsiveness from caregivers during daily interactions. Controlling child age and individual child effects, infants' gestures and signs used specifically to respond to caregivers elicited more responsiveness from caregivers during routine interactions. Understanding the effects of infants' behaviors on caregivers is critical for helping caregivers understand and improve their own behavior towards children in their care. PMID:19560826

    Sleep consolidates memory and promotes generalization in adults, but it is still unknown to what extent the rapidly growing infant memory benefits from sleep. Here we show that during sleep the infant brain reorganizes recent memories and creates semantic knowledge from individual episodic experiences. Infants aged between 9 and 16 months were given the opportunity to encode both objects as specific word meanings and categories as general word meanings. Event-related potentials indicate that, initially, infants acquire only the specific but not the general word meanings. About 1.5 h later, infants who napped during the retention period, but not infants who stayed awake, remember the specific word meanings and, moreover, successfully generalize words to novel category exemplars. Independently of age, the semantic generalization effect is correlated with sleep spindle activity during the nap, suggesting that sleep spindles are involved in infant sleep-dependent brain plasticity.

    2006-12-01

    The aim of this longitudinal study was to investigate the effect of a set of factors from multiple levels of influence: infant temperament, infant regulatory behavior, and maternal sensitivity on infant's attachment. Our sample consisted of 48 infants born prematurely and their mothers. At 1 and 3 months of age, mothers described their infants' behavior using the Escala de Temperamento do Bebé. At 3 months of age, infants' capacity to regulate stress was evaluated during Tronick's Face-to-Face Still-Face (FFSF) paradigm. At 9 months of age, mothers' sensitivity was evaluated during free play using the CARE-Index. At 12 months of age, infants' attachment security was assessed during Ainsworth's Strange Situation. A total of 16 infants were classified as securely attached, 17 as insecure-avoidant, and 15 as insecure-resistant. Mothers of securely attached infants were more likely than mothers of insecure infants to describe their infants as less difficult and to be more sensitive to their infants in free play. In turn, secure infants exhibited more positive responses during the Still-Face. Infants classified as insecure-avoidant were more likely to self-comfort during the Still-Face and had mothers who were more controlling during free play. Insecure-resistant exhibited higher levels of negative arousal during the Still-Face and had mothers who were more unresponsive in free play. These findings show that attachment quality is influenced by multiple factors, including infant temperament, coping behavior, and maternal sensitivity.

    Infant botulism is caused by the ingestion of spores of Clostridium botulinum and affects newborns and infants under 12 months of age. Ingested spores multiply and produce botulinum toxin in the digestive tract, which then induces clinical symptoms. A single French case was described in the literature prior to 1991. We describe the cases of infant botulism identified in France between 1991 and 2009. All clinical suspicions of botulism must be declared in France. Biological confirmation of the disease is provided by the National reference laboratory for anaerobic bacteria and botulism at the Pasteur Institute. During this period, 7 cases of infant botulism were identified, 1 per year from 2004 to 2008 and 2 in 2009. The median age of affected infants was 119 days and all were female. All infants presented with constipation and oculomotor symptoms. All were hospitalized and required mechanical ventilation. The infants recovered from their botulism. The diagnosis of infant botulism was biologically confirmed for all patients. One 4-month-old infant was treated with a single dose of the human-derived botulism antitoxin specific for infant botulism types A and B (BabyBIG®). The infants all had different feeding habits ranging from exclusive breast feeding to a mix of formula feeding and solid food consumption. The consumption of honey, the only documented risk food for this disease, was reported for 3 of the infants. The honey had been placed on the pacifier of 2 infants and directly in the mouth of the 3rd by the mother. Infant botulism, a form of botulism that was previously rarely recognized in France, has been reported more frequently during the last 6 years. This disease remains rare but nonetheless severe. In light of recent epidemiological data, efforts to raise awareness among parents of infants and health professionals on the danger of infant botulism and particularly, its association with honey consumption seems necessary.

  19. Pareidolia in infants.

    2015-01-01

    Faces convey primal information for our social life. This information is so primal that we sometimes find faces in non-face objects. Such illusory perception is called pareidolia. In this study, using infants' orientation behavior toward a sound source, we demonstrated that infants also perceive pareidolic faces. An image formed by four blobs and an outline was shown to infants with or without pure tones, and the time they spent looking at each blob was compared. Since the mouth is the unique sound source in a face and the literature has shown that infants older than 6 months already have sound-mouth association, increased looking time towards the bottom blob (pareidolic mouth area) during sound presentation indicated that they illusorily perceive a face in the image. Infants aged 10 and 12 months looked longer at the bottom blob under the upright-image condition, whereas no differences in looking time were observed for any blob under the inverted-image condition. However, 8-month-olds did not show any difference in looking time under both the upright and inverted conditions, suggesting that the perception of pareidolic faces, through sound association, comes to develop at around 8 to 10 months after birth.

    This study aimed to explore the effects of individualized sensory integration interventions on the sensory processing functions of preterm infants. Thirty-four preterm infants (intervention group) at a corrected age of seven months and 34 term infants (control group) were included. The preterm infants underwent an eight-week sensory integration intervention. Before and after the intervention, the preterm infants' sensory processing functions were evaluated using the Test of Sensory Functions in Infants and compared with those of term infants. Preterm infants had significantly poorer sensory processing function preintervention when compared with term infants. There was a significant improvement in preterm infants' sensory processing functions after the sensory integration intervention. In conclusion, preterm infants should be evaluated for sensory processing disorders and individualized sensory integration interventions should be implemented.

    2015-01-01

    Background Little is known on long-term survival and causes of death among individuals born small or large for gestational age. This study investigates birth weight in relation to survival and causes of death over time. Methods A national cohort of 1.7 million live-born singletons in Denmark was followed during 1979–2011, using the Danish Civil Registration System, the Medical Birth Registry and the Cause of Death Registry. Cox proportional hazards were estimated for the impact of small (SGA) and large (LGA) gestation weight and mortality overall, by age group and birth cohort. Results Compared to normal weight children, SGA children were associated with increased risk of dying over time. Though most of the deaths occurred during the first year of life, the cumulative mortality risk was increased until 30 years of age. The hazard ratios [HR] for dying among SGA children ages <2 years were: 3.47 (95% CI, 3.30–3.64) and 1.06 (95% CI, 0.60–1.87) in 30 years and older. HR for dying among SGA adults (20–29 years) were: 1.20 (95% CI, 0.99–1.46) in years 1979–1982 and 1.61 (95% CI, 1.04–2.51) in years 1989–1994. The SGA born had increased risk of dying from infection, heart disease, respiratory disease, digestive disease, congenital malformation, perinatal conditions, and accidents, suicide, and homicide. Individuals born LGA were associated with decreased mortality risk, but with increased risk of dying from malignant neoplasm. Conclusions Survival has improved independently of birth weight the past 30 years. However, children born SGA remain at significantly increased risk of dying up till they turn 30 years of age. Individuals born LGA have lower mortality risk but only in the first two years of life. PMID:26390219

    2016-01-01

    Background. Database studies have identified that public health insurance status is associated with an increased risk of severe respiratory syncytial virus (RSV) disease in US infants. However, these studies did not adjust for the presence of other risk factors and did not evaluate the risk in preterm infants. Methods. In this study, we evaluate the independent association between public insurance and severe RSV disease outcomes adjusting for other risk factors. The prospective, observational RSV Respiratory Events among Preterm Infants Outcomes and Risk Tracking (REPORT) study was conducted over 2 consecutive RSV seasons at 188 US clinical sites that enrolled preterm infants born at 32–35 wGA who had not received RSV immunoprophylaxis with palivizumab. Adjusted incidence rates per 100 infant-seasons of the RSV-associated endpoints of outpatient lower respiratory tract infection (LRI), emergency department (ED) visits, RSV hospitalizations (RSVHs), and intensive care unit admissions during peak RSV season (November–March) were compared for infants with private and public insurance. Results. Of 1642 evaluable infants enrolled in the REPORT study, 50.1% had private insurance and 49.9% had public health insurance. Adjusted rates of RSV outpatient LRIs were similar; however, rates of ED visits (hazard ratio [HR], 2.04; 95% confidence interval [CI], 1.20–3.45) were higher for subjects with public insurance, with a similar but nonsignificant trend observed for hospitalization (HR, 1.61; 95% CI, .93–2.78). Conclusions. Socioeconomic status, as evaluated by public versus private healthcare insurance, is a significant independent risk factor for ED use in US preterm infants and may contribute to increased RSVHs in this population.

    Objective Timing of delivery for the early preterm small for gestational age (SGA) fetus remains unknown. Our aim was to estimate the risk of stillbirth in the early preterm SGA fetus compared to the risk of neonatal death. Study Design We performed a retrospective cohort study of singleton pregnancies undergoing second trimester anatomy ultrasound excluding fetal anomalies, aneuploidy and pregnancies with incomplete neonatal follow-up. SGA was defined as birthweight < 10th percentile by the Alexander standard. Life-table analysis was used to calculate the cumulative risks of stillbirth/10,000 ongoing SGA pregnancies and risk of neonatal death/10,000 SGA live births for 2 week GA strata in the early preterm period (24-33 and 6/7 weeks). We further examined the composite risk of expectant management and then compared the risk of expectant management with the risk of immediate delivery. Results Of 76,453 singleton pregnancies, 7,036 SGA pregnancies meeting inclusion criteria were ongoing at 24 weeks with 64 stillbirths, 226 live births and 18 neonatal deaths between 24-33 and 6/7 weeks. As the risk of stillbirth increases with advancing GA, the risk of neonatal death falls, until the 32-33 and 6/7 week GA stratum. The relative risk of expectant management compared with immediate delivery remains <1 for each gestational age strata. Conclusion Our findings suggest the balance between the competing risks of stillbirth and neonatal death for the early preterm SGA fetus occurs at 32-33 and 6/7 weeks. These data can be useful when delivery timing remains uncertain. PMID:24746999

  12. INITIAL VALIDATION OF THE ASSESSMENT OF PARENTING TOOL: A TASK- AND DOMAIN-LEVEL MEASURE OF PARENTING SELF-EFFICACY FOR PARENTS OF INFANTS FROM BIRTH TO 24 MONTHS OF AGE.

    2016-05-01

    Parenting self-efficacy (PSE) includes parents' self-perceptions regarding their capabilities in performing the numerous and changing tasks associated with parenting a specific child (i.e., domain-specific PSE) as well as their self-perceptions in the parenting role overall (i.e., domain-general PSE). Prior literature has demonstrated PSE's relations with numerous constructs significant to mental health and the parent-infant relationship. Prior measures of PSE have been limited by focusing on only domain-specific or domain-general PSE, ignoring the importance of infant development to PSE, and other psychometric limitations. This article presents sound psychometric data for a new measure of PSE, the Assessment of Parenting Tool (APT). The APT includes task-level items on the Domain-Specific subscale (APT-DS) for each age-referenced version of the measure as well as a domain-general subscale that taps overall PSE within the first 24 months' postpartum. Initial construct validity of the measure is established, particularly for parents of infants aged 3 months and older. A stable, three-factor structure for the domain-general subscale includes "coping with being a parent," "attuned parenting," and "self-perceived model parenting." Future directions for the APT, including a revised checklist format for the domain-specific subscale, are included.

  13. Infant sleep and bedtime cereal.

    PubMed

    Macknin, M L; Medendorp, S V; Maier, M C

    1989-09-01

    We studied whether feeding infants rice cereal before bedtime promotes their sleeping through the night. One hundred six infants were randomly assigned to begin bedtime cereal feeding (1 tablespoon per ounce in a bottle) at 5 weeks or at 4 months of age. Caretakers recorded the infant's sleep from age 4 to 21 weeks for one 24-hour period per week. Sleeping through the night was defined as sleeping at least 8 consecutive hours, with the majority of time being between the hours of midnight and 6 AM. The results were also reviewed changing the requirement from 8 hours to 6 hours. There was no statistically significant trend or a consistent tendency of one group to have a higher proportion of sleepers than the other. Therefore, feeding infants rice cereal in the bottle before bedtime does not appear to make much difference in their sleeping through the night.

    Background Low- and middle-income countries continue to experience a large burden of stunting; 148 million children were estimated to be stunted, around 30–40% of all children in 2011. In many of these countries, foetal growth restriction (FGR) is common, as is subsequent growth faltering in the first 2 years. Although there is agreement that stunting involves both prenatal and postnatal growth failure, the extent to which FGR contributes to stunting and other indicators of nutritional status is uncertain. Methods Using extant longitudinal birth cohorts (n = 19) with data on birthweight, gestational age and child anthropometry (12–60 months), we estimated study-specific and pooled risk estimates of stunting, wasting and underweight by small-for-gestational age (SGA) and preterm birth. Results We grouped children according to four combinations of SGA and gestational age: adequate size-for-gestational age (AGA) and preterm; SGA and term; SGA and preterm; and AGA and term (the reference group). Relative to AGA and term, the OR (95% confidence interval) for stunting associated with AGA and preterm, SGA and term, and SGA and preterm was 1.93 (1.71, 2.18), 2.43 (2.22, 2.66) and 4.51 (3.42, 5.93), respectively. A similar magnitude of risk was also observed for wasting and underweight. Low birthweight was associated with 2.5–3.5-fold higher odds of wasting, stunting and underweight. The population attributable risk for overall SGA for outcomes of childhood stunting and wasting was 20% and 30%, respectively. Conclusions This analysis estimates that childhood undernutrition may have its origins in the foetal period, suggesting a need to intervene early, ideally during pregnancy, with interventions known to reduce FGR and preterm birth.

    Three cases of infant skeletal remains were described from the view point of personal identification. The age was exactly estimated from union of ossification centers, dental calcification and eruption. While, the sex estimation was not highly reliable, because sex differences had not clearly appeared in infant skeletons, and it was rather difficult in some cases. In infant skeletal remains, age estimation is especially important to help personal identification. The most recent photograph of a presumed person should be used for personal identification by superimposition technique since the size and proportion of infant skull constantly change as a result of its development.

    The orientation preferences of 70 infants aged 7 to 53 weeks with significant astigmatism [1.0 or more diopters (D)] were measured using a preferential looking procedure with paired gratings. The preference data show the consequences of the blurring effects of astigmatism when these are not compensatable by accommodation. Data from infant astigmats tested with optical correction look like those of nonastigmats. We have found no evidence for the development of meridional amblyopia during the first year of life.

  18. Adult brightness vs. luminance as models of infant photometry: variability, biasability, and spectral characteristics for the two age groups favor the luminance model.

    PubMed

    Teller, Davida Y; Pereverzeva, Maria; Civan, Andrea L

    2003-01-01

    When infants fail to make chromatic discriminations, do the characteristics of their performance minima coincide more closely with the properties of adult luminance matches or heterochromatic brightness matches? In addition to their spectral properties, adult luminance matches are typically characterized by relatively small individual differences, whereas brightness matches are believed to be both more variable and more biasable. Two complementary experiments were carried out on adults and 8-week-old infant subjects. Both groups were tested with small (1.5 degrees to 4 degrees ) red and blue test fields of varying luminances, embedded in a white surround. In adults, heterochromatic brightness matches were measured. Individual differences spanned about 0.5 log units, and brightness matches could be biased by as much as 0.8 log units by varying the range of test field luminances. In infants, the locations of performance minima were measured. Individual differences spanned less than 0.1 log units, the mean performance minima coincided with predictions based on V10(lambda), and the location of the performance minimum was nearly unaffected by the range of test field luminances used. Thus by all three criteria, these data suggest that infants' performance minima are mediated by luminance rather than by brightness signals. To date there remains no evidence that the infant visual system computes a brightness signal.

    2015-01-01

    Objectives. We examined potential synergistic effects of racial and socioeconomic inequality associated with small-for-gestational-age (SGA) birth. Methods. Electronic medical records from singleton births to White and Black women in 10 US states and the District of Columbia (n = 121 758) were linked to state-level indicators of structural racism, including the ratios of Blacks to Whites who were employed, were incarcerated, and had a bachelor’s or higher degree. We used state-level Gini coefficients to assess income inequality. Generalized estimating equations models were used to quantify the adjusted odds of SGA birth associated with each indicator and the joint effects of structural racism and income inequality. Results. Structural racism indicators were associated with higher odds of SGA birth, and similar effects were observed for both races. The joint effects of racial and income inequality were significantly associated with SGA birth only when levels of both were high; in areas with high inequality levels, adjusted odds ratios ranged from 1.81 to 2.11 for the 3 structural racism indicators. Conclusions. High levels of racial inequality and socioeconomic inequality appear to increase the risk of SGA birth, particularly when they co-occur. PMID:26066964

    The melatonin levels in various body fluids of the sudden infant death syndrome (SIDS) infants are compared with those of infants of comparable age who died of other causes to examine a possible relationship between pineal function and SIDS. After adjusting for age differences, cerebrospinal fluid melatonin levels are found to be significantly lower in the SIDS infants. It is suggested that diminished melatonin production may be characteristic of SIDS and could represent an impairment in the maturation of physiologic circadian organization.

    2004-09-01

    The purpose of this study was to identify the social process of infant care among Cherokee mothers. Nineteen informants, who had an infant less than 2 years of age, were interviewed. The data were analyzed using the technique of constant comparative analysis. A social process of Indian infant care among Cherokee mothers was identified. Eight concepts emerged from data analysis. The first and principal concept, being a Cherokee mother, describes the functions of being an Indian mother in Cherokee society. The other seven concepts describe the patterns of cultural care the mothers provided to their infants. These included accommodating everyday infant care, accommodating health perspectives, building a care-providing consortium, living spiritually, merging the infant into Indian culture, using noncoercive discipline techniques, and vigilantly watching for the natural unfolding of the infant. Trustworthiness and credibility of the generated theory were evaluated through multiple measures. PMID:15296577

    This study examined the effects of prenatal cocaine exposure on infant hypothalamic-pituitary-adrenal axis activity and reactivity at 7 months of infant age. Participants were 168 caregiver-infant dyads (87 cocaine exposed, 81 not cocaine exposed; 47% boys). Maternal behavior, caregiving instability, and infant growth and behavior were assessed, and children's saliva was sampled before, during, and after standardized procedures designed to elicit emotional arousal. Results revealed cocaine-exposed infants had a high amplitude trajectory of cortisol reactivity compared to non-cocaine-exposed infants. Infant gender and caregiving instability moderated this association. The findings support a dual hazard vulnerability model and have implications for evolutionary-developmental theories of individual differences in biological sensitivity to context. PMID:19467009

    O'Connor, Nina R

    2009-04-01

    Although the American Academy of Pediatrics and the American Academy of Family Physicians recommend breast milk for optimal infant nutrition, many parents still choose formula as an acceptable alternative. The wide variety of available formulas is confusing to parents and physicians, but formulas can be classified according to three basic criteria: caloric density, carbohydrate source, and protein composition. Most infants require a term formula with iron. There is insufficient evidence to recommend supplementation with docosahexaenoic acid or arachidonic acid. Soy formulas are indicated for congenital lactase deficiency and galactosemia, but are not recommended for colic because of insufficient evidence of benefit. Hypoallergenic formulas with extensively hydrolyzed protein are effective for the treatment of milk protein allergy and the prevention of atopic disease in high-risk infants. Antireflux formulas decrease emesis and regurgitation, but have not been shown to affect growth or development. Most infants with reflux require no treatment. Family physicians can use these guidelines to counsel parents about infant formula, countering consumer advertising that is not evidence-based. PMID:19378873

    The Dietary Guidelines for Americans (DGA) are the cornerstone of US government efforts to promote health and prevent disease through diet and nutrition. The DGA currently provides guidelines for ages ≥2 y. In an effort to determine the strength of the evidence to support the inclusion of infants and children from birth to age 24 mo, the partner agencies led by the Department of Health and Human Services Office of Disease Prevention and Health Promotion and the USDA Center for Nutrition Program and Policy initiated the project entitled “Evaluating the evidence base to support the inclusion of infants and children from birth to 24 months of age in the Dietary Guidelines for Americans—the B-24 Project.” This project represents the first step in the process of applying systematic reviews to the process of deciding whether the evidence is sufficient to include this age group in future editions of the DGA. This supplement includes the B-24 Executive Summary, which describes the B-24 Project and the deliberations of the 4 working groups during the process of developing priority topics for the systematic review, and a research agenda to address the critical gaps. Also included in this supplement issue is an article on the Nutrition Evidence Library methodology for developing systematic review questions and articles from the invited content presenters at the B-24 Prime meeting.

    Objective To identify factors associated with infant sleep location. Methods Demographic information and infant care practices were assessed for 708 mothers of infants ages 0 to 8 months at Women, Infants and Children centers (WIC). Generalized linear latent mixed models were constructed for the outcome, sleeping arrangement last night (bedsharing with infants vs. roomsharing without bedsharing, and versus sleeping in separate rooms). Results Two-thirds of the mothers were black. 48.6% roomshared without bedsharing; 32.5% bedshared; and 18.9% slept in separate rooms. Compared with infants who slept in separate rooms, infants who roomshared without bedsharing were more likely to be Hispanic (OR 2.58, 95%CI 1.11–5.98) and younger (3.66 and 1.74 times more likely for infants 0–1 month and 2–3 months old respectively as compared with older infants). Compared with infants who bedshared, those that roomshared without bedsharing were more likely to be 0–1 month old (1.57, 1.05–2.35), and less likely to be black (0.43, 0.26–0.70) or have a teenage mother (0.37, 0.23–0.58). Conclusions Approximately one-third of mothers and infants bedshare despite increased risk of sudden infant death syndrome (SIDS). The factors associated with bedsharing are also associated with SIDS likely rendering infants with these characteristics at high risk for SIDS. PMID:18582898

    Background Nowadays, one of the major public health problems among children is growth failure. It can be characterized in terms of either inadequate growth or the inability to maintain growth. Objectives The main objective of this study was to examine the effects of some factors on growth failure among a sample of infants less than two years old. Materials and Methods The present longitudinal archival study relied on data gathered from health files from February 2007 to July 2010 for 1,358 children under two years of age, selected from eight health centers in the east and northeast parts of Tehran, Iran. In the present study, growth failure refers to at least a 50 g decrease in an infant’s weight as recorded at each attendance in comparison to the previous measurement. The impacts of risk indicators were assessed using the Bayesian hierarchical logistic regression modeling technique. Results The highest and lowest percentage of growth failure was 5.8% and 0.1%, respectively, in the eleventh and the first month after birth. The obtained results from the Bayesian hierarchical modeling revealed that diarrhea (95% credible interval (CrI): 0.70 - 3.31), discontinuation of breastfeeding (95% CrI: 0.77 - 5.96), and respiratory infections (95% CrI: 2.07 - 4.61) were significant risk factors for growth failure. The random term at the child level was significant (95% CrI: 0.74 - 7.82), while the variation in centers was extremely small (95% CrI: 0.004 - 4.22). Conclusions It was noted that a relatively high prevalence of growth failure was observed in the study sample. For minimizing the impact of significant risk factors on growth failure, the early detection of growth failure and its risk indicators is of great importance. In addition, when the focus of the analysis is on the different nested sources of variability and the data has a hierarchical structure, using a hierarchical modeling approach is recommended to achieve more accurate results.

    If acute leukemia is the most frequent cancer in childhood (33%), it remains a very rare diagnosis in infants less than one year old, e.g. less than 5% of cases. At this age, the frequency of acute lymphoblastic leukemia (ALL) (almost all of B-lineage) is quite similar to the one of myeloblastic forms (AML). Infant leukemia frequently presents with high hyperleucocytosis, major tumoral burden and numerous extra-hematological features, especially in central nervous system and skin. Whatever the lineage, the leukemic cell is often very immature cytologically and immunologically. Rearrangements of the Mixed Lineage Leukemia (MLL) gene, located on band 11q23, are the hallmark of these immature leukemias and confer a particular resistance to conventional approaches, corticosteroids and chemotherapy. The immaturity of infants less than 1-year-old is associated to a decrease of the tolerable dose-intensity of some drugs (anthracyclines, alkylating agents) or asks questions about some procedures like radiotherapy or high dose conditioning regimen, responsible of inacceptable acute and late toxicities. The high level of severe infectious diseases and other high-grade side effects limits also the capacity to cure these infants. The survival of infants less than 1-year-old with AML is only 50% but similar to older children. On the other hand, survival of those with ALL is the same, then quite limited comparing the 80% survival in children over one year. Allogeneic stem cell transplantations are indicated in high-risk subgroups of infant ALL (age below 6 months, high hyperleucocytosis >300.10(9)/L, MLL-rearrangement, initial poor prednisone response). However, morbidity and mortality remain very important and these approaches cannot be extended to all cases. During the neonatal period, the dismal prognosis linked to the high number of primary failures or very early relapses and uncertainties about the late toxicities question physicians about ethics. It is an emergency to

    Faces convey primal information for our social life. This information is so primal that we sometimes find faces in non-face objects. Such illusory perception is called pareidolia. In this study, using infants’ orientation behavior toward a sound source, we demonstrated that infants also perceive pareidolic faces. An image formed by four blobs and an outline was shown to infants with or without pure tones, and the time they spent looking at each blob was compared. Since the mouth is the unique sound source in a face and the literature has shown that infants older than 6 months already have sound-mouth association, increased looking time towards the bottom blob (pareidolic mouth area) during sound presentation indicated that they illusorily perceive a face in the image. Infants aged 10 and 12 months looked longer at the bottom blob under the upright-image condition, whereas no differences in looking time were observed for any blob under the inverted-image condition. However, 8-month-olds did not show any difference in looking time under both the upright and inverted conditions, suggesting that the perception of pareidolic faces, through sound association, comes to develop at around 8 to 10 months after birth.

    2001-01-01

    This study of mothers and infants from the Dogon ethnic group of Mali, West Africa examined three attachment hypotheses: (1) that infant attachment security is linked to the quality of mother-infant communication, (2) that mothers of secure infants respond more sensitively to their infants than do mothers of insecure infants, and (3) that infant disorganization is linked to maternal frightened or frightening behaviors. Participants were 27 mother-infant pairs from a rural town and 15 mother-infant pairs from two agrarian villages; infants ranged in age from 10 to 12.5 months at the first assessment. The distribution of the Strange Situation classifications was 67% secure, 0% avoidant, 8% resistant, and 25% disorganized. Infant attachment security was significantly related to the quality of mother-infant communication as observed in a well-infant exam. The correlation between infant attachment security ratings and maternal sensitivity (assessed in the home) was modest and approached significance. Mothers of disorganized infants had significantly higher ratings of frightened or frightening behaviors. Maternal sensitivity predicted little of the variance in infant security; however, the addition of the frightened/frightening variable in the regression equation tripled the explained variance. The findings are discussed in light of Dogon childrearing practices and key tenets of attachment theory.

    Vaccination against measles, mumps, rubella and varicella (MMRV) is currently recommended in developed countries for infants from 12 months of age. However, measles vaccination at 9 months of age is recommended by the WHO in the Expanded Program on Immunization (EPI) schedule and it is therefore possible that MMR or MMRV vaccines might also be given at this age. This open-label, randomised, comparative study evaluated the immunogenicity and safety of a 2-dose schedule of ProQuad(®) (MMRV vaccine) given at a 3-month interval in healthy infants aged ≥9 months. For measles, the non-inferiority of the response rate post-Dose 2 was reached when Dose 1 was administered at 11 months (98%) compared with 12 months (99%) but was not reached when Dose 1 was administered at 9 months (95%). The response rate to measles post-Dose 1 increased with age, from 73% to 88% and 90% at 9, 11 and 12 months, respectively. For mumps, rubella and varicella, response rates were not different after Dose 1 (>95%) or Dose 2 (>99%) regardless of whether Dose 1 was administered at 9, 11 or 12 months of age. In conclusion, the age of administration of the first of a two-dose regimen of ProQuad may be lowered to 11 months. Dose 1 may be administered at 9 months if early protection is required, but it should be recognised that a second dose is required promptly with a minimum of 3-month interval between doses.

    The present investigation explored the question of whether walking onset is related to infant language development. Study 1 used a longitudinal design (N = 44) to assess infant locomotor and language development every 2 weeks from 10 to 13.5 months of age. The acquisition of walking was associated with a significant increase in both receptive and productive language, independent of age. Study 2 used an age-held-constant study with 12.5-month-old infants (38 crawling infants; 37 walking infants) to further explore these findings. Results from Study 2 replicated the differences in infant language development between locomotor groups. Additionally, a naturalistic observation of parent-infant interactions (20 crawling dyads; 24 walking dyads) revealed that language development was predicted by multiple factors in the social environment, but only for walking infants. Possible explanations of the findings (e.g., social, cognitive, neurological) are discussed, and topics for future research are highlighted.

    Neighborhood deprivation is consistently associated with greater risk of low birthweight. However, large birth size is increasingly relevant but overlooked in neighborhood health research, and proximity within which neighborhood deprivation may affect birth outcomes is unknown. We estimated race/ethnic-specific effects of neighborhood deprivation index (NDI) within 1, 3, 5, and 8 km buffers around Oregon Pregnancy Risk Assessment Monitoring System (n=3,716; 2004-2007) respondents’ homes on small and large for gestational age (SGA, LGA). NDI was positively associated with LGA and SGA in most race/ethnic groups. The results varied little across the four buffer sizes. PMID:25240489

    Background: Breast milk is known as the most crucial postpartum issue in metabolic and immunologic programming of neonatal health. Human milk microbial changes over Lactation. The factors influencing the milk microbiome as well as potential impact of microbes on infant health have not yet been discovered. The objective was to identify pre- and post-natal factors that can potentially influence the bacterial communities inhabiting human milk. Materials and Methods: Breast milk samples (n = 40) with all full-term breastfed infants were collected from lactating randomized. Information on personal characteristics, dietary habits, information about infants were collected after birth. The samples were plated with serial dilutions on three selective culture media man rogosa sharp and then colonies were counted. Colonies tested for catalase reaction, Gram-staining and microscopic examination. Results: The result of this study showed that the overall incidence of positive Lactobacillus in mother's milk was 87.5%. The results based on (infant gender, mode of delivery, rural or urban and lactation time) rural or urban and lactation time were significant (P < 0.05). The results showed that all of the variables were significant in this regression model (P < 0.001). The median of log10 Lactobacillus counts in rural mothers, vaginal delivery, infant male gender and Lactation time for first 3-month were meaningfully high. Conclusions: The findings of this study about the breast milk Lactobacillus potential probiotic bacteria of healthy Iranian mothers, suggested that the breast milk microbiome is significantly influenced by several factors, mode of delivery, rural or urban and lactation time.

    The aim was to demonstrate the immunogenicity and safety of a DTaP-IPV//PRP-T combined vaccine (Pentaxim(®)) compared to individual vaccines in infants in the People's Republic of China. Infants (N=792) were randomly assigned to receive DTaP-IPV//PRP-T at 2, 3 and 4 months of age (Group A) or 3, 4 and 5 months of age (Group B), or DTaP (Wuhan Institute of Biological Products), PRP-T (Act-Hib(®)) and IPV (Imovax(®) Polio) at 3, 4 and 5 months of age (Group C). Antibody titers were measured pre- and 1 month after the third vaccination; non-inferiority analyses were performed for seroprotection/seroconversion (SP/SC) rates. Safety was assessed 1 month after the primary series. SP/SC rates for the DTaP-IPV//PRP-T vaccine were high and non-inferior to the controls. Reactogenicity was low for each group and no hypotonic hyporesponsive episode or seizure was reported. In conclusion, the DTaP-IPV//PRP-T vaccine was highly immunogenic, non-inferior to the commercially available control vaccines and had a good safety profile for both primary administration schedules.

    To estimate the association between multiple domains of physical activity and risk of small-for-gestational-age (SGA) birth. We utilized data from 1,040 participants in the Latina Gestational Diabetes Mellitus Study, a prospective cohort of predominantly Puerto Rican prenatal care patients in Massachusetts. Physical activity was assessed by bilingual interviewers using a modified version of the Kaiser physical activity survey in early (mean = 15 weeks) and mid pregnancy (mean = 28 weeks). Physical activity (i.e., sports/exercise, household, occupational, and active living) in pre, early and mid pregnancy was categorized in quartiles. SGA was classified as <10th percentile of birth weight for gestational age. Pre- and early-pregnancy physical activity were not associated with SGA. In multivariable analyses, women with high total activity in mid-pregnancy had a decreased risk of SGA [risk ratio (RR) = 0.42; 95% confidence interval (CI) 0.21-0.82; p(trend) = 0.003] as compared to those with low total activity. Findings were similar for high household activity (RR = 0.69; 95% CI = 0.34-1.40; p(trend) = 0.26), active living (RR = 0.63; 95% CI = 0.35-1.13; p(trend) = 0.04), and occupational activity (RR = 0.79, 95% CI = 0.47-1.34; p(trend) = 0.26). High levels of sports/exercise were associated with an increased SGA risk without a significant dose-response association (RR = 2.14, 95% CI 1.04-4.39; p(trend) = 0.33). Results extend prior studies of physical activity and SGA to the Hispanic population.

    Weekly increments of length, weight, head circumference, and skinfold thickness in response to a series of dietary changes were measured in 108 healthy infants who weighed less than 1.3 kg at birth. The serial manipulations included prevention of late metabolic acidosis, increased caloric intake, and calcium, sodium, and phosphorus supplementation. The study comprised four phases; the infants were divided into ten groups according to dietary regimen. AGA and SGA infants were studied separately. Growth in length was primarily influenced by a change to a formula providing a higher caloric intake and a 60:40 whey protein/casein ratio. Correction of late metabolic acidosis, sodium, and phosphorus supplementation had minor additive effects on growth in length. Increased caloric intake also influenced growth of head circumference, but only in AGA infants. Only the sodium intake was shown to influence body weight increments significantly with the range of caloric intake used in the study (132 to 160 calories/kg/day).

    Objectives Compare the dietary intake of young adults born small for gestational age (SGA) versus those born appropriate for gestational age (AGA). Design Cross-sectional analysis. Setting Data at the 8-year follow-up Haguenau cohort (France). Data from 229 AGA-born adults and 172 SGA-born adults with available dietary information are presented. Methods Dietary intake was based on a food questionnaire including 19 items. The χ2 test was run to compare intake between SGA-born and AGA-born individuals. An a priori score was calculated based on the adherence to recommendations from the French Nutrition and Health Program and included 8 components with the lowest value indicating a lower adherence to recommendations. The score was then divided into quartiles. Relative risks and 95% CIs, controlling for age and sex in multivariate analysis, were calculated in order to determine the risk of belonging to the first versus the second to the fourth quartiles in SGA-born and AGA-born individuals. Results Intakes of SGA-born adults indicated that they consumed more meat, sugar and less fish than AGA-born individuals (all p<0.05). Multivariate analyses with adjustment for age and sex showed that the relative risk of belonging to the first quartile versus the other three quartiles did not disclose any significant difference in SGA-born versus AGA-born participants: RR=0.92 (95% CI 0.65 to 1.30). Conclusions Aside from the differences found by univariate analyses, no significant differences were obtained in multivariate analyses. Findings suggest that parameters of fetal programming are more associated with the development of metabolic syndrome in adulthood rather than dietary patterns. PMID:27473954

    This study evaluated the effects of head growth compromise beginning in utero and continuing, in some cases, through the first 9 months of life on the cognitive and literacy skills of school-age small-for-gestational-age (SGA) children. Seventy-one SGA children, aged 7 to 9 years (gestational ages, 24-41 weeks) and 16 full-term appropriate-for-gestational-age control children of comparable socioeconomic backgrounds and age at testing completed tests assessing intelligence, receptive language, working memory, problem solving, visual-motor integration, phonological awareness, reading, and spelling. SGA children were subdivided into head-growth pattern groups based on their head circumference at birth and at 9 months postterm. Analyses showed that SGA children with poor prenatal and postnatal head growth had the worst outcomes, followed by those with prenatal brain compromise, but good postnatal head growth. SGA children with preserved head growth in utero as well as good head growth after birth demonstrated the best outcomes, although spelling skills were deficient relative to full-term peers. The Verbal and Full Scale IQ ratings of the SGA children who had experienced brain compromise in utero declined significantly from 5 to 8 years of age. We conclude that mild intrauterine growth retardation (IUGR) has a minimal effect on the development of cognitive or academic abilities, providing that brain growth in utero is not affected. IUGR that slows brain growth in utero impairs the acquisition of some cognitive and academic abilities, even when followed by good catch-up head growth after birth, whereas poor brain growth in utero followed by little or no catch-up head growth results in widespread impairments. Findings highlight the limits to brain plasticity and emphasize the importance of optimal prenatal and postnatal brain growth.

    The purpose of the present study was to investigate whether infant temperament and previous feeding history were associated with infants' acceptance and rejection of a novel food at 12 months of age. Mother-infant dyads (n = 89) were video-recorded during a novel food (hummus, cottage cheese) feeding task. Infants' reactions (acceptance and rejection behaviors) and maternal responsiveness and affect during the interaction were coded from the recordings by teams of coders. Mothers reported on their infants' temperamental approach via the Infant Behavior Questionnaire-Revised (IBQ-R) and their infants' feeding history (previous exposure to solid foods and exclusive breastfeeding). Regression analyses revealed that infants rated lower on approach showed less acceptance of the first offer of novel food than infants rated higher on approach. Additionally, low approach infants who were previously exposed to a greater number of solid foods showed fewer rejection behaviors in response to the later offers of food. Exclusive breastfeeding for 4 months did not appear to have an effect on acceptance or rejection. Finally, greater maternal responsiveness was related to the infants' acceptance of the new food whereas lower maternal responsiveness was associated with rejection of the novel food. These results suggest that the acceptance and rejection of new foods by infants is dependent upon their temperament and previous exposure to solid foods, as well as the manner in which mothers present the novel food.

    Preeclampsia and retinopathy of prematurity (ROP) are associated with impaired angiogenesis. Previous studies on the relationship between preeclampsia and ROP have produced conflicting results. The goal of this study was to evaluate the association between maternal preeclampsia and ROP using a large population-based cohort of very-low-birth-weight (VLBW) infants from 21 neonatal departments registered in the database of the Premature Baby Foundation of Taiwan. Multivariable logistic regression analysis was used to estimate the adjusted odds ratios (OR) and 95% confidence intervals (CI) for preeclampsia with reference to ROP and severe ROP. A total of 5,718 VLBW infants (844 cases with maternal preeclampsia) were included for analysis. The overall incidences of mild and severe ROP were 36.0% and 12.2%, respectively. Univariable analysis showed lower GA and lower birth weight, vaginal delivery, non-SGA, RDS, PDA, sepsis, transfusion, and absence of maternal preeclampsia to be associated with mild and severe ROP development. However, OR (95% CI) adjusted for the variables that were significant according to univariable analysis showed the risks of developing any-stage ROP and severe ROP for maternal preeclampsia to be 1.00 (0.84-1.20) and 0.89 (0.63-1.25), respectively. The results remained unchanged in stratified analyses according to SGA status. Our data showed that maternal preeclampsia was not associated with the subsequent development of any stage or severe ROP in VLBW infants.

    Previous work has shown that preterm infants are at higher risk for cognitive/language delays than full-term infants. Recent studies, focusing on prosody (i.e. rhythm, intonation), have suggested that prosodic perception development in preterms is indexed by maturational rather than postnatal/listening age. However, because prosody is heard…

    This report is based on a review of the present situation of the sudden infant death syndrome through the presentation of four cases studied at the Unidad de Pediatría, Hospital General de México, S.S.A. All cases were in apparent good health before death. All babies were less than ten months of age. In three cases, necropsy was not performed, and the other one did not show significant abnormalities at the post-mortem examination. A complete review of the literature was made including: historical, epidemiological, genetic, clinical and pathological aspects. Special emphasis is made on the pathophysiology of the syndrome during MOR phase of sleep and muscular hypertrophy of the lungs arteriolae suggesting chronic hypoxia which are the most relevant theories in the sudden infant death syndrome. Psychological aspects and the family management by the physician and detection of possible future victims of the syndrome are finally discussed. PMID:973858

    Severe nutritional deficiencies developed in four infants from a new vegan religious community. They had received breast milk until the age of 3 months; thereafter, breast milk was supplemented with or replaced by extremely low caloric-density preparations. All of the infants had profound protein-caloric malnutrition, severe rickets, osteoporosis, and vitamin B12 and other deficiencies. One infant died, while the three others had an uneventful recovery. After discharge of the infants from the hospital, the community responded well to a modification of the infants' diet, which did not violate their vegetarian philosophy. However, they refused to give their infants vitamin B12 on a regular basis.

    Botulism is a rare neuromuscular condition, and multiple clinical forms are recognized. Infant botulism was first identified in the 1970s, and it typically occurs in infants younger than 1 year of age who ingest Clostridium botulinum spores. A specific treatment for infant botulism, intravenous botulism immunoglobulin (BIG-IV or BabyBIG®), was developed in 2003, and this treatment has substantially decreased both morbidity and hospital costs associated with this illness. This article will review the pathogenesis of infant botulism as well as the epidemiology, clinical manifestations, diagnosis, and treatment of this condition.

  6. An Opinion on "Staging" of Infant Formula: A Developmental Perspective on Infant Feeding.

    PubMed

    Lönnerdal, Bo; Hernell, Olle

    2016-01-01

    Breast milk is a dynamic fluid with compositional changes occurring throughout the period of lactation. Some of these changes in nutrient concentrations reflect the successively slowing growth rate and developmental changes in metabolic requirements that infants undergo during the first year of life. Infant formula, in contrast, has a static composition, intended to meet the nutritional requirements of infants from birth to 6 or 12 months of age. To better fit the metabolic needs of infants and to avoid nutrient limitations or excesses, we suggest that infant formulas should change in composition with the age of the infant, that is, different formulas are created/used for different ages during the first year of life. We propose that specific formulas for 0 to 3 months (stage 1), 3 to 6 months (stage 2), and 6 to 12 months (stage 3) of age may be nutritionally and physiologically advantageous to infants. Although this initially may impose some difficult practical/conceptual issues, we believe that this staging concept would improve nutrition of formula-fed infants and, ultimately, improve outcomes and make their performance more similar to that of breast-fed infants.

  7. Bilingual exposure influences infant VOT perception.

    Linking the discrimination of voice onset time (VOT) in infancy with infant language background, we examine the perceptual changes of two VOT contrasts (/b/-/p/ and /p(h)/-/p/) by Dutch monolingual and bilingual infants from 8 to 15 months of age. Results showed that language exposure and language dominance had a strong impact on monolingual and bilingual infant VOT perceptual patterns. In addition, perceptual turbulence was found at 8-9 months for bilingual infants, and stabilized perception was presented for all infants from 11 months onwards. We thus report a general input-driven developmental VOT perception in both monolingual and bilingual infants, with perceptual turbulence for bilinguals in the second half of the first year of life.

    The Sanitation Hygiene Infant Nutrition Efficacy (SHINE) trial is designed to measure the independent and combined effects of improved water, sanitation, and hygiene and improved infant feeding on child stunting and anemia in Zimbabwe. We developed and pilot-tested the infant feeding intervention delivered by 9 village health workers to 19 mothers of infants aged 7-12 months. Between September 2010 and January 2011, maternal knowledge was assessed using mixed methods, and infant nutrient intakes were assessed by 24-hour recall. We observed positive shifts in mothers' knowledge. At baseline, 63% of infants met their energy requirement and most did not receive enough folate, zinc, or calcium; none met their iron requirement. Postintervention, all infants received sufficient fat and vitamin A, and most consumed enough daily energy (79%), protein (95%), calcium (89%), zinc (89%), folate (68%), and iron (68%). The SHINE trial infant feeding intervention led to significant short-term improvements in maternal learning and infant nutrient intakes.

  10. Infant Social Development across the Transition from Crawling to Walking

    Walle, Eric A.

    2016-01-01

    The onset of walking is a developmental transition that sets in motion a cascade of change across a range of domains, including social interactions and language learning. However, research on the unfolding of such change in the infant across this transition is limited. This investigation utilized a longitudinal design to examine the effect of walking acquisition on infant social development and parent perceptions of the infant to explore how changes in these factors relate with infant language development. Parents reported on infant social behaviors and their perception of the infant, as well as motor and language development, in 2-week intervals from 10.5 to 13 months of age. Mixed linear models revealed infant initiation of joint engagement (e.g., pointing, bringing objects to the parent) and following of the parent's joint engagement cues (e.g., point following, gaze following) increased as a function of infant walking experience, particularly between 2- and 4-weeks after the onset of walking, independent of age. Additionally, the parent's perception of the infant as an individual increased between 2- and 4-weeks after the infant began to walk. Finally, the unique relations of infant walking experience, following of social cues, and the parents' perception of the infant as an individual with infant language development were examined. Infant following of joint engagement behaviors and parent perception of the infant as an individual were related to receptive, but not productive, vocabulary size. Additionally, infant walking experience remained a significant predictor of infant receptive and productive language. These findings provide insight on important factors that change as the infant begins to walk. Future research utilizing more direct assessment of these factors is described, as well as general patterning of developmental change across the transition from crawling to walking. PMID:27445923

    Dengue virus (DV) infection causes either a benign syndrome, dengue fever, or a severe syndrome, dengue haemorrhagic fever/dengue shock syndrome (DHF/DSS), that is characterized by systemic capillary leakage, thrombocytopaenia and hypovolaemic shock. DHF/DSS occur mainly due to secondary infection by a heterotype DV infection in children and adults but in infants even primary infection by DV causes DHF/DSS. Clinical manifestations of DHF/DSS are more significantly associated with death in infants compared with older children. Vertical transmission of DV and anti-DV IgG has been well reported and is responsible for the pathogenesis of DV disease and its manifestations in infants. The complex pathogenesis of DHF/DSS during primary dengue in infants, with multiple age-related confounding factors, offers unique challenges to investigators. Dengue in infants is not often studied in detail due to practical limitations, but looking at the magnitude of DHF/DSS in infants and the unique opportunities this model provides, there is a need to focus on this problem. This paper reviews existing knowledge on this aspect of DV infection and the challenges it provides.

    Aim: Debatable issues in the management of inguinal hernia in premature infants remain unresolved. This study reviews our experience in the management of inguinal hernia in premature infants. Materials and Methods: Retrospective chart review of premature infants with inguinal hernia from 1999 to 2009. Infants were grouped into 2: Group 1 had repair (HR) just before discharge from the neonatal intensive care unit (NICU) and Group 2 after discharge. Results: Eighty four premature infants were identified. None of 23 infants in Group 1 developed incarcerated hernia while waiting for repair. Of the 61 infants in Group 2, 47 (77%) underwent day surgery repair and 14 were admitted for repair. At repair mean postconceptional age (PCA) in Group1 was 39.5 ± 3.05 weeks. Mean PCA in Group 2 was 66.5 ± 42.73 weeks for day surgery infants and 47.03 ± 8.87 weeks for admitted infants. None of the 84 infants had an episode of postoperative apnea. Five (5.9%) infants presented subsequently with metachronous contralateral hernia and the same number of infants had hernia recurrence. Conclusions: Delaying HR in premature infants until ready for discharge from the NICU allows for repair closer to term without increasing the risk of incarceration. Because of low occurrence of metachronous hernia contralateral inguinal exploration is not justified. Day surgery HR can be performed in former premature infant if PCA is >47 weeks without increasing postoperative complications. PMID:25552826

    Our objective was to examine whether high blood pressure in the preconception period was associated with low birth weight (LBW) and small-for-gestational age (SGA) in Chinese women. Data were obtained from the China-US Collaborative Project for Neural Tube Defects Prevention, a large population-based cohort study. We included 43 718 singleton live births delivered at gestational ages of 28-45 weeks to women who were registered before pregnancy in 7 counties in southern China. Blood pressure was measured during registration by trained healthcare workers, and other health-related information was recorded prospectively. We used logistic regression to evaluate the associations between preconception blood pressure and the risk of LBW and SGA, adjusting for potential confounders. The prevalence of hypertension in the preconception study population was 4.62% (2019/43 718). The incidences of LBW and SGA were 2.33% and 5.05% for the hypertension group and 2.01% and 5.68% for the nonhypertension group. Compared with the nonhypertension group, the hypertension group did not show significantly increased risk for LBW overall (adjusted risk ratio =1.16, 95% confidence interval 0.86-1.57) or SGA (adjusted risk ratio =0.89, 95% confidence interval 0.73-1.09). When participants with normal blood pressure were used as the reference, the adjusted risk ratio of SGA for prehypertensive women was 1.13 (95% confidence interval 1.03-1.25). Our results do not support an association between hypertension or higher blood pressure before pregnancy and increased risk of LBW or SGA.

  6. Unnatural sudden infant death

    PubMed Central

    Meadow, R.

    1999-01-01

    AIM—To identify features to help paediatricians differentiate between natural and unnatural infant deaths.
METHOD—Clinical features of 81 children judged by criminal and family courts to have been killed by their parents were studied. Health and social service records, court documents, and records from meetings with parents, relatives, and social workers were studied.
RESULTS—Initially, 42 children had been certified as dying from sudden infant death syndrome (SIDS), and 29 were given another cause of natural death. In 24 families, more than one child died; 58died before the age of 6 months and most died in the afternoon or evening. Seventy per cent had experienced unexplained illnesses; over half were admitted to hospital within the previous month, and 15 had been discharged within 24 hours of death. The mother, father, or both were responsible for death in 43, five, and two families, respectively. Most homes were disadvantaged—no regular income, receiving income support—and mothers smoked. Half the perpetrators had a history of somatising or factitious disorder. Death was usually by smothering and 43% of children had bruises, petechiae, or blood on the face.
CONCLUSIONS—Although certain features are indicative of unnatural infant death, some are also associated with SIDS. Despite the recent reduction in numbers of infants dying suddenly, inadequacies in the assessment of their deaths exist. Until a thorough postmortem examination is combined with evaluation of the history and circumstances of death by an experienced paediatrician, most cases of covert fatal abuse will go undetected. The term SIDS requires revision or abandonment.

    2015-01-01

    Background: Brain tumors in infants have different clinical presentations, anatomical distribution, histopathological diagnosis, and clinical prognosis compared with older children. Materials and Methods: A retrospective analysis was done in patients <12 months old who were operated on for primary brain tumor in Children's Hospital Medical Center since 2008 to 2014. Results: Thirty-one infants, 20 males and 11 females, with the mean age of 7.13 months (0.5–12) were enrolled. There were 16 supratentorial and 15 infratentorial tumors. The presenting symptoms included increased head circumference (16); bulge fontanel (15); vomiting (15); developmental regression (11); sunset eye (7); seizure (4); loss of consciousness (4); irritability (3); nystagmus (2); visual loss (2); hemiparesis (2); torticollis (2); VI palsy (3); VII, IX, X nerve palsy (each 2); and ptosis (1). Gross total and subtotal resection were performed in 19 and 11 cases, respectively. Fourteen patients needed external ventricular drainage in the perioperative period, from whom four infants required a ventriculoperitoneal shunt. One patient underwent ventriculoperitoneal shunting without tumor resection. The most common histological diagnoses were primitive neuroectodermal tumor (7), followed by anaplastic ependymoma (6) and grade II ependymoma. The rate of 30-day mortality was 19.3%. Eighteen patients are now well-controlled with or without adjuvant therapy (overall survival; 58%), from whom 13 cases are tumor free (disease free survival; 41.9%), 3 cases have residual masses with fixed or decreased size (progression-free survival; 9.6%), and 2 cases are still on chemotherapy. Conclusion: Brain tumors in infants should be treated with surgical resection, followed by chemotherapy when necessary. PMID:26962338

    Background Controversy exists about how much, if any, weight obese pregnant women should gain. While the revised Institute of Medicine guidelines on gestational weight gain (GWG) in 2009 recommended a weight gain of 5–9 kg for obese pregnant women, many studies suggested even gestational weight loss (GWL) for obese women. Objectives A systematic review was conducted to summarize pregnancy outcomes in obese women with GWL compared to GWG within the 2009 Institute of Medicine guidelines (5–9 kg). Design Five databases were searched from 1 January 2009 to 31 July 2014. The Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA Statement were followed. A modified version of the Newcastle-Ottawa scale was used to assess individual study quality. Small for gestational age (SGA), large for gestational age (LGA) and preterm birth were our primary outcomes. Results Six cohort studies were included, none of which assessed preterm birth. Compared to GWG within the guidelines, women with GWL had higher odds of SGA <10th percentile (adjusted odds ratio [AOR] 1.76; 95% confidence interval [CI] 1.45–2.14) and SGA <3rd percentile (AOR 1.62; 95% CI 1.19–2.20) but lower odds of LGA >90th percentile (AOR 0.57; 95% CI 0.52–0.62). There was a trend towards a graded relationship between SGA <10th percentile and each of three obesity classes (I: AOR 1.73; 95% CI 1.53–1.97; II: AOR 1.63; 95% CI 1.44–1.85 and III: AOR 1.39; 95% CI 1.17–1.66, respectively). Conclusion Despite decreased odds of LGA, increased odds of SGA and a lack of information on preterm birth indicate that GWL should not be advocated in general for obese women. PMID:26196130

    Vietnam plans to replace the routine childhood diphtheria, pertussis and tetanus combination (DPT) vaccine with a pentavalent vaccine. The present study was performed to assess the immunogenicity and safety of the combined diphtheria, tetanus, whole-cell pertussis, hepatitis B (HepB), and Haemophilus influenzae type b (Hib) (DTwP-HepB-Hib) Quinvaxem® vaccine in children. A total of 131 infants received the Quinvaxem® vaccine at 2, 3 and 4 months. Antibody levels were measured at baseline, at one month after the third injection and one year after the first injection. Seroprotection rates were high for each vaccine antigen at one month after the third dose: 93.1% for diphtheria, 98.5% for tetanus, 99.2% for pertussis (seroconversion rate), 93.1% for HepB, and 100% for Hib (anti-PRP ≥ 0.15 µg/ml). The rate of children with protective antibodies persisting at one year after the first dose was 88.4% for diphtheria, 49.6% for pertussis, 82.2% for tetanus, 76.7% for HepB and 97.7% for Hib (anti-PRP ≥ 0.15 µg/ml). The Quinvaxem® vaccine was well tolerated and has a low rate of adverse events. Quinvaxem® given at 2, 3 and 4 months of age was immunogenic and safe for primary immunization among infants in Vietnam. PMID:26867396

    The regulation of insulin-like growth factor-binding protein 3 (IGFBP3) gene expression is complex, because it can be induced by agents that both stimulate and inhibit the proliferation. The principal aim of this study was to investigate whether p73, a member of the p53 gene family, has a role in the regulation of the IGFBP3 expression and whether this regulation occurs in a context of cell survival or death. We demonstrate that IGFBP3 is a direct TAp73α (the p73 isoform that contains the trans-activation domain) target gene and activates the expression of IGFBP3 in actively proliferating cells. As IGFBP3 plays a key role in regulating the growth hormone/insulin-like growth factor type 1 (GH/IGF1) axis, whose alterations in gene expression appear to have a role in the growth failure of children born small for gestational age (SGA), we measured the mRNA expression levels of p73 and IGFBP3 in a group of SGA children. We found that mRNA expression levels of p73 and IGFBP3 are significantly lower in SGA children compared with controls and, in particular, p73 mRNA expression is significantly lower in SGA children with respect to height. Our results shed light on the intricate GH/IGF pathway, suggesting p73 as a good biomarker of the clinical risk for SGA children to remain short in adulthood. PMID:26063735

    Using historical cohorts of healthy, acutely ill, and chronically ill infants for comparison, we sought to determine whether infants with sickle cell disease (SCD) have impaired health-related quality of life (HRQL). We conducted a cross-sectional study at 2 sites: the Medical College of Wisconsin/Children's of Wisconsin and the University of Alabama School of Medicine/Children's of Alabama. Parents of 90 infants with SCD completed the PedsQL Infant Module corresponding to their infant's age (1 to 12 mo or 13 to 24 mo) during a regular clinic visit. At 1 to 12 months, infants with SCD displayed lower Physical HRQL than healthy infants, but better HRQL than chronically ill infants. By 13 to 24 months, infants with SCD had worse HRQL in all areas than healthy infants and worse Physical and Total HRQL than acutely ill infants. Compared with chronically ill infants in this age group, infants with SCD had similar Physical HRQL and better Psychosocial and Total HRQL. By 13 to 24 months, a greater proportion of infants with SCD had impaired Physical and Total HRQL compared with infants aged 1 to 12 months. All differences were significant at the (P<0.05) level. Impaired HRQL can be detected in infants with SCD.

    This study investigated effects of profound hearing loss on mother-infant interactions before and after cochlear implantation with a focus on maternal synchrony, complexity, and directiveness. Participants included two groups of mother-infant dyads: 9 dyads of mothers and infants with normal hearing; and 9 dyads of hearing mothers and infants with profound hearing loss. Dyads were observed at two time points: Time 1, scheduled to occur before cochlear implantation for infants with profound hearing loss (mean age=13.6 months); and Time 2 (mean age=23.3 months), scheduled to occur approximately six months after cochlear implantation. Hearing infants were age-matched to infants with hearing loss at both time points. Dependent variables included the proportion of maternal utterances that overlapped infant vocalizations, maternal mean length of utterance, infant word use, and combined maternal directives and prohibitions. Results showed mothers' utterances overlapped the vocalizations of infants with hearing loss more often before cochlear implantation than after, mothers used less complex utterances with infants with cochlear implants compared to hearing peers (Time 2), and mothers of infants with profound hearing loss used frequent directives and prohibitions both before and after cochlear implantation. Together, mothers and infants adapted relatively quickly to infants' access to cochlear implants, showing improved interactional synchrony, increased infant word use, and levels of maternal language complexity compatible with infants' word use, all within seven months of cochlear implant activation.

    Premature birth is a significant cause of infant and child morbidity and mortality. In the United States, the premature birth rate, which had steadily increased during the 1990s and early 2000s, has decreased annually for four years and is now approximately 11.5%. Human viability, defined as gestational age at which the chance of survival is 50%, is currently approximately 23–24 weeks in developed countries. Infant girls, on average, have better outcomes than infant boys. A relatively uncomplicated course in the intensive care nursery for an extremely premature infant results in a discharge date close to the prenatal EDC. Despite technological advances and efforts of child health experts during the last generation, the extremely premature infant (less than 28 weeks gestation) and extremely low birth weight infant (ELBW) (< 1000 grams) remain at high risk for death and disability with 30–50% mortality and, in survivors, at least 20–50% risk of morbidity. The introduction of CPAP, mechanical ventilation, and exogenous surfactant increased survival and spurred the development of neonatal intensive care in the 1970s through the early 1990s. Routine administration of antenatal steroids during premature labor improved neonatal mortality and morbidity in the late 1990s. The recognition that chronic postnatal administration of steroids to infants should be avoided may have improved outcomes in the early 2000s. Evidence from recent trials attempting to define the appropriate target for oxygen saturation in preterm infants suggests arterial oxygen saturation between 91–95% (compared to 85–89%) avoids excess mortality. However, final analyses of data from these trials have not been published, so definitive recommendations are still pending The development of neonatal neurocognitive care visits may improve neurocognitive outcomes in this high-risk group.

    In the Western world, independent toilet training usually starts at age 18 months or later. In Asia and Africa, assisted toilet training traditionally starts between one and three months and is completed within approximately one year. This article reports a male infant who started caregiver-assisted toilet training at age 33 days in a Western family setting. During the first days, the caregiver made observations of the infant's bowel movement schedule and the cues he provided, from which she learned when to assist him to eliminate in the bathroom. During the elimination process, the infant was held in an "in-arms" position, with close contact between the infant's back and the caregiver's chest. Meanwhile, the caregiver gave vocal signals to prompt the infant to eliminate. Successful bowel training was completed at five months. This case report shows that early infant toilet training is possible in a Western family setting if the caregiver properly learns the infant's natural elimination timing and signals.

    Objective To compare the interactive behaviors of American Indian mothers and their premature infants with those of African American mothers and their premature infants. Design Descriptive, comparative study. Setting Three neonatal intensive care units and two pediatric clinics in the southeast. Participants Seventy-seven mother-infant dyads: 17 American Indian mother-infant dyads and 60 African American mother-infant dyads. Methods Videotapes of mother-infant interactions and the Home Observation for Measurement of the Environment (HOME) were used to assess the interactions of the mothers and their premature infants at six months corrected age. Results American Indian mothers looked more, gestured more, and were more often the primary caregivers to their infants than the African American mothers. American Indian infants expressed more positive affect and gestured more to their mothers, whereas African American infants engaged in more non-negative vocalization toward their mothers. African American mothers scored higher on the HOME subscales of provision of appropriate play materials and parental involvement with the infant. American Indian mothers scored higher on the opportunities for variety in daily living subscale. Conclusion Although many of the interactive behaviors of American Indian and African American mother-infant dyads were similar, some differences did occur. Clinicians need to be aware of the cultural differences in mother-infant interactions. To optimize child developmental outcomes, nurses need to support mothers in their continuation or adoption of positive interactive behaviors. PMID:23682698

  2. Young Infants Match Facial and Vocal Emotional Expressions of Other Infants

    Research has demonstrated that infants recognize emotional expressions of adults in the first half-year of life. We extended this research to a new domain, infant perception of the expressions of other infants. In an intermodal matching procedure, 3.5- and 5-month-old infants heard a series of infant vocal expressions (positive and negative affect) along with side-by-side dynamic videos in which one infant conveyed positive facial affect and another infant conveyed negative facial affect. Results demonstrated that 5-month-olds matched the vocal expressions with the affectively congruent facial expressions, whereas 3.5-month-olds showed no evidence of matching. These findings indicate that by 5 months of age, infants detect, discriminate, and match the facial and vocal affective displays of other infants. Further, because the facial and vocal expressions were portrayed by different infants and shared no face-voice synchrony, temporal or intensity patterning, matching was likely based on detection of a more general affective valence common to the face and voice.

    Infants prefer speech to non-vocal sounds and to non-human vocalizations, and they prefer happy-sounding speech to neutral speech. They also exhibit an interest in singing, but there is little knowledge of their relative interest in speech and singing. The present study explored infants' attention to unfamiliar audio samples of speech and singing. In Experiment 1, infants 4–13 months of age were exposed to happy-sounding infant-directed speech vs. hummed lullabies by the same woman. They listened significantly longer to the speech, which had considerably greater acoustic variability and expressiveness, than to the lullabies. In Experiment 2, infants of comparable age who heard the lyrics of a Turkish children's song spoken vs. sung in a joyful/happy manner did not exhibit differential listening. Infants in Experiment 3 heard the happily sung lyrics of the Turkish children's song vs. a version that was spoken in an adult-directed or affectively neutral manner. They listened significantly longer to the sung version. Overall, happy voice quality rather than vocal mode (speech or singing) was the principal contributor to infant attention, regardless of age.

    Little is known about the relationship between maternal behavior and the stability of premature infants' physiologic responses during feeding. In a secondary data analysis, we examined relationships between quality of maternal behavior and cardiorespiratory physiology during feeding in 61 premature and 53 term infants at four times over the first year of life. Measures included heart rate (HR), respiratory rate (RR), and oxygen saturation; Child Feeding Skills Checklist; and Parent-Child Early Relational Assessment. Birthweight, gestational age, and neurodevelopmental risk were covariates. Quality of maternal behavior did not predict infants' physiologic response to feeding. However, birthweight was related to infant feeding physiology among all infants over the first year of life. Stress during fetal life, which may lead to impaired intrauterine growth and low birthweight, may have longitudinal effects on cardiorespiratory functioning of premature infants. Research is needed to further investigate the biological pathways by which maternal-infant interaction supports behavioral and physiologic feeding outcomes of premature infants.

    Mothers’ own milk is the best source of nutrition for nearly all infants. Beyond somatic growth, breast milk as a biologic fluid has a variety of other benefits, including modulation of postnatal intestinal function, immune ontogeny, and brain development. Although breastfeeding is highly recommended, breastfeeding may not always be possible, suitable or solely adequate. Infant formula is an industrially produced substitute for infant consumption. Infant formula attempts to mimic the nutritional composition of breast milk as closely as possible, and is based on cow’s milk or soymilk. A number of alternatives to cow’s milk-based formula also exist. In this article, we review the nutritional information of breast milk and infant formulas for better understanding of the importance of breastfeeding and the uses of infant formula from birth to 12 months of age when a substitute form of nutrition is required.

    The infantile form of primary hyperoxaluria type-1 (PH-1) is characterized by a rapid progression to the end-stage renal disease (ESRD) due to both increased oxalate load and reduced glomerular filtration rate. In the literature, data on this form are limited. The purpose of this study is to analyze retrospectively the clinical, biological, and radiological features of children who were diagnosed with PH-1 during the 1(st) year of life. We reviewed the records of all children with PH-1 diagnosed and followed-up at our department between January 1995 and December 2013. Among them, only infants younger than 12 months of age were retrospectively enrolled in the study. Fourteen infants with the median age of two months were enrolled in the study. At diagnosis, 11 patients had ESRD. All patients had nephrocalcinosis and two of them had calculi. The diagnosis was established in nine patients on the basis of the positive family history of PH-1, bilateral nephrocalcinosis, and quantitative crystalluria. In four patients, the diagnosis was made with molecular analysis of DNA. Kidney biopsy contributed to the diagnosis in one patient. During follow-up, two patients were pyridoxine sensitive and preserved renal function. Seven among 11 patients who had ESRD died, four patients are currently undergoing peritoneal dialysis. Children with infantile PH and ESRD are at high risk of early death. Peritoneal dialysis is not a treatment of choice. Combined liver-kidney transplantation is mandatory. PMID:27215245

    We examined the effects of infant age and gender on the behaviors of infants and mothers during discipline interactions using longitudinal, naturalistic, home-based, taped observations of 16 mother-infant dyads (eight males and eight females). These observations were conducted between the child ages of 5 and 12 months and used a devised Maternal Discipline Coding System to code for the occurrence of discipline events. During discipline interactions, mothers vocalized longer, used harsher tones, and used more explanations with older compared to younger infants. Male infants were more likely than female infants to cry or whine during discipline events. Mothers of male infants used longer vocalizations, more words, and more affectionate terms than mothers of female infants. Male infants were more difficult during discipline interactions than female infants, but it appeared that mothers of males responded to this difficulty by using milder discipline techniques.

  8. Study protocol: the relation of birth weight and infant growth trajectories with physical fitness, physical activity and sedentary behavior at 8-9 years of age - the ABCD study

    PubMed Central

    2013-01-01

    Background Low birth weight and accelerated infant growth have been identified as independent risk factors for childhood and adult obesity and cardiovascular disease. This led to the ‘Developmental Origins of Health and Disease’ (DOHaD) hypothesis, stating that environmental factors during pregnancy and early postnatal life affect disease risk in later life. There is growing evidence that perinatal factors may influence adult health through the programming of energy balance regulation, including sedentary behavior and physical activity. The present study focuses on the influence of birth weight and infant growth on physical fitness, physical activity and sedentary behavior in 8-9 year old children, as this might partly explain the higher obesity and cardiovascular risk associated with low birth weight and accelerated infant growth. In addition, this study provides the opportunity for a validation study of a linguistic and cross-cultural translated physical activity questionnaire compared to accelerometer data. This article describes the study protocol for this study. Methods/Design This is a study embedded in the Amsterdam Born Children and their Development (ABCD) birth cohort. In 200 children of Dutch ethnicity, physical fitness, physical activity and sedentary behavior were assessed at age 8-9. We measured aerobic fitness using the 20 meter multistage shuttle run test, and neuromuscular fitness using the standing broad jump and handgrip strength test. Sedentary behavior and physical activity levels were measured using accelerometry. All children also completed a translated physical activity questionnaire, the scores of which will be compared to accelerometry data to assess the construct validity of the questionnaire in Dutch school-aged children. Discussion This study will be the first population-based prospective cohort study to address the association of both prenatal and postnatal growth with physical fitness and objectively-assessed physical activity and

    It is unclear why children of adolescent mothers experience more developmental problems than children of adult mothers. There has been minimal systematic investigation of whether there is a relationship between the young age of the mother and her mothering behaviors. Our data fail to demonstrate any relationship between adolescent maternal age and the counts of maternal behaviors three days following birth. Seventy-five normal primiparous mothers less than 20 years old were videotaped with their normal infants for ten minutes in a standardized laboratory setting during the three days following birth. The frequency of maternal behaviors was counted from the videotapes by trained observers. Future studies of primiparous adolescent mothers should consider the effects of maternal race/culture and socioeconomic status on their mothering behaviors. The relationship between adolescent maternal age and the vocalizations expressed by the mother to her infant should also be explored further.

    Objective The objective of this study is to measure aortic intima-media thickness (aIMT) and aortic diameter (AD) in appropriate for gestational age (AGA) fetuses, small for gestational age (SGA) fetuses, and intrauterine growth restricted (IUGR) fetuses. Methods Case-control study performed between June 2011 and June 2012. Forty-nine AGA fetuses, 40 SGA fetuses, and 35 IUGR fetuses underwent concomitant measurement of aIMT and AD at a mean gestational age of 34.4 weeks. Results Median aIMT was higher in fetuses with IUGR (0.504 mm [95%CI: 0.477-0.530 mm]), than in SGA fetuses (0.466 mm [95% CI: 0.447–0.485 mm]), and AGA fetuses (0.471 mm [95% CI: 0.454-0.488 mm]) (p = 0.023). Mean AD was significantly lower in fetuses with IUGR (4.451 mm [95% CI: 4.258–4.655 mm]), than in AGA fetuses (4.74 mm [95% CI: 4.63-4.843 mm]) (p = 0.028). Conclusions Growth restricted fetuses have a thicker aortic wall than AGA and SGA fetuses, which possibly represents preclinical atherosclerosis and a predisposition to later cardiovascular disease.

    To date, no study has evaluated changes in oral labial angle as preterm infants mature. The main purpose of this study was to document goniometer measurements of the labial angle of the mouth in preterm infants, to assess changes with development, to compare to findings in healthy term infants, and also evaluate oral motor reflexes in these groups. Seventy-eight preterm infants and 45 healthy term infants were recruited for the prospective study. Labial angle was assessed via goniometer, and oral motor reflexes and the volume of milk ingested were evaluated. There was significant difference between term and preterm infants' labial angles (P < .01). The distribution of preterm infants' angles were similar to term infants' by 36 to 40 weeks' postmenstrual age. Goniometer measurements of the oral labial angle may reveal oral motor performance in preterm infants and may be relevant for feeding skills assessment in this group of infants.

    Both horizontal and vertical binocular disparities produce depth perception in adults. In developmental studies, infants aged around 4 to 6 months were shown to perceive depth from horizontal disparity. However, infants' sensitivity to vertical disparity has not been shown clearly. To examine the sensitivity in infants, this study measured preferential looking behavior of infants aged 20 to 27 weeks. Results showed a significant preference for the stimulus with vertical disparity, providing the first evidence of infants' sensitivity to vertical disparity. The infants in the same age group did not show preference for stimulus with horizontal disparity when the stimulus were comparable to the stimulus with vertical disparity, while their sensitivity to horizontal disparity was confirmed with the stimuli used in a previous study. Our results would suggest that properties in processing horizontal and vertical disparities are different in infancy, and that the sensitivity to horizontal disparity are still premature in 27 weeks after birth.
