    The aim of this pilot research was to investigate whether infants of mothers with panic disorder (PD) would be at higher risk for prematurity and low birth weight (corrected for gestational age) than controls. Medical records were reviewed for 25 mothers with PD and 33 mothers without a lifetime history of anxiety disorders or other major psychopathology as determined by diagnostic interview. Mothers also completed questionnaires concerning demographic information and life stresses. Compared to controls, infants with PD mothers were not significantly more likely to be born prematurely or earlier than controls but did show smaller birth weight corrected for gestational age, even after accounting for possible confounding influences. Additional research is needed to confirm these preliminary findings. Studying PD mothers during pregnancy could provide insight concerning mechanisms for the development of low birth weight and psychopathology.

    Full Text Available Background: Prematurity is the most common cause of death and disability And Preterm infants, are prone to developmental complications. For this reason this study was designed for follow up of these babies until 2 years by modified DDST-2. Methods: This study was a prospective longitudinal descriptive study from March 2009 to March 2011 in clinic of sheikh and Imam Reza Hospitals, mashhad, Iran. Sample size with Confidence coefficient of 95% and power 80%, was determined 100 hundred babies. Infants were seen by a pediatrician at a follow up clinic at 1, 3, 6, 9,12,15,18, 24, months.The developmental assessment was done using Denver-2 Developmental Screening Test. Results: mean age for smiling was 4/6 ± 2/1  months which significantly differed with appropriate age (p = 0.000, mean age for telling two syllables words 11/7±  1/9 months, without significant difference of appropriate age.(p = 0.139. Average age for understanding NO was 10/4±  2/0 months that significantly differed with appropriate age(p = 0.000. The average age for telling 6 word was 17/8±  3/0, without significant difference with appropriate age (p = 0.510. Conclusion: Children with history of prematurity and low birth weight have more disability and developmental delay so they need to developmental screening tests.

    Molecular, as opposed to microscopic, detection measures the real prevalence of Plasmodium falciparum infections. Such occult infections are common during pregnancy but their impact on pregnancy outcomes is unclear. We performed a longitudinal study to describe that impact. In a cohort of 1037 Beninese pregnant women, we used ultrasound to accurately estimate gestational ages. Infection with P. falciparum, hemoglobin concentration, use of intermittent preventive treatment during pregnancy (IPTp) for malaria, and other parameters were recorded during pregnancy. Using multivariate analyses, we evaluated the impact of submicroscopic infections on maternal anemia, premature birth, and low birth weight. At inclusion, polymerase chain reaction (PCR) and microscopy detected infection in 40% and 16% of women, respectively. The proportion infected declined markedly after 2 doses of IPTp but rebounded to 34% (by PCR) at delivery. Submicroscopic infections during pregnancy were associated with lower mean hemoglobin irrespective of gravidity, and with increased anemia risk in primigravidae (odds ratio [OR], 2.23; 95% confidence interval [CI], .98-5.07). Prospectively, submicroscopic infections at inclusion were associated with significantly increased risks of low birth weight in primigravidae (OR, 6.09; 95% CI, 1.16-31.95) and premature births in multigravidae (OR, 2.25; 95% CI, 1.13-4.46). In this detailed longitudinal study, we document the deleterious impact of submicroscopic P. falciparum parasitemia during pregnancy on multiple pregnancy outcomes. Parasitemia occurs frequently during pregnancy, but routine microscopic and rapid diagnostic tests fail to detect the vast majority of episodes. Our findings imply caution in any revision of the current strategies for prevention of pregnancy-associated malaria. © The Author 2015.

    Full Text Available Background: Thyroid function disorders, particularly congenital hypothyroidism (CHT, are important endocrine dysfunctions associated with permanent morbidities. CHT is more prevalent among preterm low-birth-weight neonates compared to term infants with normal weight. Methods: This prospective cohort study was conducted on 126 very-low-birth-weight (VLBW neonates referred to the neonatal intensive care units (NICUs of two tertiary referral hospitals affiliated to Isfahan University of Medical Sciences in Isfahan, Iran during 2012-2014. On day five of birth and two, four, and six weeks after birth, blood samples were collected from the infants to determine thyroid function disorders, including transient hypothyroxinemia, neonatal hypothyroidism, transient primary neonatal hypothyroidism, and transient hyperthyrotropinemia. Results: In total, 126 infants with mean gestational age of 30.5±2.29 weeks and mean birth weight of 1246.90±193.58 g were enrolled in this study. Thyroid-stimulating hormone (TSH level of Conclusion: According to the results of this study, thyroid function disorders are relatively common in preterm VLBW neonates, and serum T4 level is correlated with gestational age in these infants. Therefore, thyroid function tests with a consistent protocol are required for premature infants. It is recommended that further research be performed on larger sample sizes to investigate the prevalence of thyroid function disorders in preterm infants.

    Objective: the present study was aimed at analyzing the value of the early diagnosis of hemodynamic changes in hemorrhages and hypoxic-ischemic events in premature, very-low-birth-weight neonates through the evaluation of images and resistance index measurement by means of transcranial Doppler ultrasonography. Materials and methods: fifty premature, very-low-birth-weight neonates were submitted to transcranial Doppler ultrasonography with sequential transfontanellar and transtemporal techniques. Results: cerebral abnormalities were detected in 32% of the neonates (22% with intracranial hemorrhage, 8% with periventricular leukomalacia, and 2% with toxoplasmosis). Among the 34 cases (68%) of neonates in whom no brain lesion was detected at transcranial Doppler ultrasonography, 18 (53%) presented changes in the resistance index. Such resistance index varied according to the time of the examination. Conclusion: there is a correlation between the presence of cerebral hemodynamic changes demonstrated by resistance index measurements and the subsequent development of hemorrhages and hypoxic-ischemic lesions. Although not being a death predictor, changes in the resistance index are associated with the severity of the clinical conditions in preterm, very-low-birth-weight neonates. (author)

    Full Text Available In this retrospective case series, we report the spectrum and outcomes of aggressive posterior retinopathy of prematurity (APROP in infants ≥1500 g birth weight. Twenty-nine eyes of 15 infants are included. All infants were referred from level I or II nurseries, received supplemental unmonitored oxygen for prolonged duration (>1 week and had multiple systemic co-morbidities. Of the 29 eyes, 10 (34.5% had zone 1 and 19 (65.5% had posterior zone 2 disease. Twenty-five (86.2% eyes had flat neovascularization and 4 (13.8% eyes had brush like proliferation. We noticed large vascular loops in 10 (34.5% eyes. After confluent laser photocoagulation, 22 (75.9% eyes had a favorable outcome. The study concludes that APROP in heavier (≥1500 g birth weight premature infants occurs mostly in posterior zone 2 with flat neovascularization and atypical features like large vascular loops. Supplemental unmonitored oxygen for prolonged duration and multiple systemic co-morbidities could be a contributing factor.

    The main determinants of the risk of mortality in the neonatal period are low birth weight and premature birth. The study sought to analyze the adequacy of prenatal care and risk factors associated with premature birth and low birth weight in a northeastern Brazilian capital. This is a case-control study. A model for adequacy of prenatal conditions composed of four indicators was created. Descriptive statistics for univariate analysis were used; as well as Wald linear trend tests, Student's t and chi-square test for bivariate analysis and multiple logistic regression for multivariate analysis with p prenatal care, variable indicator III remained significant, showing that mothers who had inadequate prenatal care had an increased chance for the occurrence of the outcome, highlighting the need for adequate public health policies of care for pregnant women in the municipality under scrutiny.

    Full Text Available Background: To understand the characteristics, ophthalmic outcomes, and risk factors of retinopathy of prematurity (ROP in patients with birth weight (BW greater than 1500 g. The applicability of the ROP screening criteria to the Taiwanese population was also examined. Methods: The study included 104 eyes from 54 ROP patients who had BW greater than 1500 g from 1981 to 2008. Demographic information, disease courses, ophthalmic outcomes, and possible systemic risk factors were recorded. The infants were divided into groups of mild and severe ROP for a risk factor analysis. Results: The mean gestational age (GA of the infants was 31 ± 1.3 weeks, and the mean BW was 1675 ± 249 g. Mild ROP regressed in 94 eyes (90%, and 10 eyes (10% developed severe ROP. After various treatments, the regression rates for prethreshold or threshold ROP (n = 8 and stage 4 ROP (n = 2 were 100% and 50%, respectively. Forty-eight patients (85% had at least three associated systemic risk factors. A multiple logistic regression analysis revealed that patients with an intraventricular hemorrhage were found to have an increased chance of developing severe ROP, especially those with BW greater than 1500 g (p = 0.015. There was also a significant association between patients who had severe ROP and an increased risk of having cerebral palsy (CP at 1.5 years of age (p = 0.013. Conclusion: The majority of patients with BW greater than 1500 g developed mild ROP. However, advanced ROP with poor visual outcome was also encountered in some patients.

    Full Text Available Abstract Background Adverse birth outcomes such as low birth weight and premature birth have been previously linked with exposure to ambient air pollution. Most studies relied on a limited number of monitors in the region of interest, which can introduce exposure error or restrict the analysis to persons living near a monitor, which reduces sample size and generalizability and may create selection bias. Methods We evaluated the relationship between premature birth and birth weight with exposure to ambient particulate matter (PM2.5 levels during pregnancy in Massachusetts for a 9-year period (2000–2008. Building on a novel method we developed for predicting daily PM2.5 at the spatial resolution of a 10x10km grid across New-England, we estimated the average exposure during 30 and 90 days prior to birth as well as the full pregnancy period for each mother. We used linear and logistic mixed models to estimate the association between PM2.5 exposure and birth weight (among full term births and PM2.5 exposure and preterm birth adjusting for infant sex, maternal age, maternal race, mean income, maternal education level, prenatal care, gestational age, maternal smoking, percent of open space near mothers residence, average traffic density and mothers health. Results Birth weight was negatively associated with PM2.5 across all tested periods. For example, a 10 μg/m3 increase of PM2.5 exposure during the entire pregnancy was significantly associated with a decrease of 13.80 g [95% confidence interval (CI = −21.10, -6.05] in birth weight after controlling for other factors, including traffic exposure. The odds ratio for a premature birth was 1.06 (95% confidence interval (CI = 1.01–1.13 for each 10 μg/m3 increase of PM2.5 exposure during the entire pregnancy period.

    2009-03-01

    Full Text Available Objective: Retinopathy of prematurity (ROP is a disease of the eye caused by disorganized growth of retinal blood vessels resulting in scarring and retinal detachment. All preterm babies are at high risk for ROP, and very low birth weight is an additional risk factor. An increased incidence of ROP is expected in Iran because of improved survival of low birth weight and premature babies, and it is obvious that pediatricians and ophthalmologists are concerned about prevention and timely treatment of ROP in these children. To asses the real situation of ROP in our NICU we studied its prevalence and risk factors. Methods: This was a retrospective analysis of premature infants with birth weight of ≤1500 grams or gestational age of ≤32 weeks, admitted April 1, 2005 to March 28, 2006, to the Neonatal Intensive Care Unit of Qaem Hospital, Mashhad, Iran. The collected data of 47 cases in this cross-sectional study are analyzed by SPSS (Mann_Whitney, t-Student. Findings: Forty five infants were included in the study. Out of these, 4 (8.5% developed ROP (inclusive all stages. Our analysis revealed that low gestational age, sepsis and respiratory distress syndrome were independent predictors for the development of ROP. Conclusion:The frequency of ROP in our hospital was lower than the range reported in developed countries, and our risk factors were a little different.

    Full Text Available ABSTRACT Purpose: To analyze ocular biometry parameters and evaluate their relationship with gestational age, birth weight, and postmenstrual age in prematurely born infants. Methods: The right eyes of 361 premature infants born before the 36th gestational week were evaluated. Birth weight, gestational week, and gender were recorded. An A-scan Biometer was used for obtaining axial measurements, including anterior chamber depth, lens thickness, vitreous length, and total axial length. Results: Gestational age and birth weight values ranged from 23 to 36 weeks and from 560 to 2,670 g, respectively. The mean gestational age and birth weight were 30.8 ± 2.8 weeks and 1,497.9 ± 483.6 g, respectively. During the first examination (4-5 weeks of postnatal age, birth weight and gestational age of the infants correlated significantly and positively with lens thickness, vitreous length, and axial length (r>0.5, p<0.001, but not with anterior chamber depth (r<0.5. Increased vitreous and axial lengths correlated significantly with increasing postmenstrual age of the infants (r=0.669, p<0.001; r=0.845, p<0.001, respectively. Conclusions: Lens thickness, vitreous length, and axial length, but not anterior chamber depth, were significantly correlated with birth weight and gestational age. All four parameters increased with increasing postmenstrual age, with higher correlations for vitreous and axial lengths than for anterior chamber depth and lens thickness. It was concluded that axial elongation resulted primarily from increasing posterior chamber length.

    Intracardiac repair for complex congenital heart defects in premature neonates with very low birth weight (VLBW) is still a challenge to pediatric cardiac surgeons. We report the successful rerouting of cardiac type total anomalous pulmonary venous return (TAPVR) in a premature newborn (36th gestational week) with VLBW (1250 g). She had severe hypoxemia and low cardiac output despite medical treatment. Rerouting surgery of TAPVR was performed under deep hypothermia circulatory arrest at the age of 20 days. The sternum was left open and approximated 2 days later. Follow-up echocardiography showed good ventricular function without pulmonary venous obstruction. The endotracheal tube was removed 7 days postoperatively. She was then discharged without complication. In conclusion, with improved cardiopulmonary bypass technique and perioperative care, open heart surgery can be performed in premature newborns with VLBW.

    Full Text Available Background: Feeding intolerance is a common problem among premature infants. There is limited information on the safety and effects of oral probiotic supplements, especially products containing Lactobacillus reuteri, and the incidence of necrotizing enterocolitis (NEC in low birth weight preterm infants. This study aimed to evaluate the effects of Lactobacillus reuteri on the gastrointestinal complications and feeding tolerance in premature infants. Methods: This randomized triple-blind clinical trial was conducted on 60 premature infants divided into two groups of intervention and placebo. Subjects in the intervention group received one drop/kg of supplementary oral probiotic with 0.5 ml of distilled water, and infants in the placebo group only received 0.5 ml of distilled water. Probiotic administration continued to reach full enteral feeding. Results: In this study, mean time to reach full enteral feeding was 12.83 and 16.75 days in the intervention and placebo groups, respectively, which was indicative of a significant difference (P=0.01. However, mean of neonatal weight at discharge had no significant difference between the two groups. In addition, 6.7% and 36.7% of infants in the intervention and placebo groups were diagnosed with NEC, respectively, which showed a significant difference (P=0.005. Also, prevalence of jaundice and sepsis was not significantly different between the study groups. Conclusion: According to the results of this study, Lactobacillus reuteri could reduce the time to reach full enteral feeding while diminishing the incidence of NEC in very low birth weight premature infants.

    Full Text Available 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.

    In this study, we describe trends in morbidity and mortality of preterm infants with less than 500mg birth weight in the changing landscape of obstetric and neonatal care. During a ten year study period between 2006 and 2016 we assessed outcome data for all neonates with less than 500mg birth weight born at our Neonatal Intensive Care Unit. We divided study subjects into two groups based on whether their birth date fell in the first half (2006-2010; n=39) versus the second half (2011-2015; n=27) of the study period comparing clinical outcomes in the two groups. We also assessed several clinical parameters for association with postnatal survival by comparing relative frequencies for each clinical parameter among surviving infants versus mortality cases. Survival rate for preterm neonates with less than 500mg birth weight born between 2006 and 2010 was 30.8%. This survival rate rose to 70.4% in the second half of the study period between 2011 and 2015 (ppremature birth was found to be predominantly associated with maternal hypertension or intrauterine growth restriction while in those who died premature birth due to premature rupture of membranes and spontaneous preterm labor were significantly more common. All surviving infants with less than 500mg birth weight were born via cesarean section whereas among those who died cesarean section had been performed in only 80% and vaginal delivery in 20% representing a significant difference between the groups (ppremature neonates with less than 500mg birth weight preterm delivery due to premature rupture of membranes and intrauterine infections represents the worse mortality risk. Steroid prophylaxis and measures to prevent and treat intrauterine infections with appropriate use of antibiotics can markedly improve survival in these cases. In premature neonates with less than 500mg birth weight survival is more favorable after cesarean section compared to vaginal delivery. Copyright © 2017. Published by Elsevier B.V.

    Full Text Available There seems to be consensus that intrauterine influences during human development have long-term implications. The hypothesis has been raised that alterations in an individual’s life cycle provoke lesions, some of them irreversible. The objectives of this study were: (1 to call attention to the problem of distance effects of neuromotor performance, prematurity and low birth weight in children and youngsters; (2 to present relevant aspects of the conceptual framework of fetal programming and its interpretive relevance for deficits in motor performance and coordination. A Pubmed database search was performed using different key words and their possible combinations. Cross-sectional, longitudinal and case-control studies evaluating motor performance and fetal programming were selected. Motor deficit levels ranged from 4% to 51% in the European population and from 4% to 56% in the North American population. A study involving the Australian population reported a motor coordination deficit of 9.5%. There is no absolute agreement regarding the extent, reversibility and significance of motor deficits in view of the wide variability in deficit levels. The mechanisms that will induce problems in the neuromotor development of children, youngsters and adults under adverse conditions of fetal development are unknown and cannot be compensated for by sensorimotor stimulation.

    To evaluate outcomes after surgical ligation (SL) of patent ductus arteriosus (PDA) in premature, extremely low birth weight (ELBW) infants. Optimal management of PDA in this specialized population remains undefined. Currently, surgical therapy is largely reserved for infants failing medical management. To date, a large-scale, risk-matched population-based study has not been performed to evaluate differences in mortality and resource utilization. Data on identified premature (Propensity score-matched analysis of 1620 SL versus 1584 non-SL found reduced mortality (15% vs 26%) and more routine disposition (48% vs 41%) for SL (P Propensity score-matched analysis demonstrates reduced mortality in premature/ELBW infants with SL for PDA. NEC and sepsis are predictors of mortality and resource utilization.

    Full Text Available Purpose. The objective of our study was to examine a possible influence of gestational age, birth weight, and Apgar score on amplitudes and latencies of P100 wave in preterm born school-age children. Materials and Methods. We examined the following group of school-age children: 28 with history of prematurity (mean age 10.56 ± 1.66 years and 25 born at term (mean age 11.2 ± 1.94 years. The monocular PVEP was performed in all children. Results. The P100 wave amplitudes and latencies significantly differ between preterm born school-age children and those born at term. There was an essential positive linear correlation of the P100 wave amplitudes with birth weight, gestational age, and Apgar score. There were the negative linear correlations of P100 latencies in 15-minute stimulation from O1 and Oz electrode with Apgar score and O1 and O2 electrode with gestational age. Conclusions. PVEP responses vary in preterm born children in comparison to term. Low birth weight, early gestational age, and poor baseline output seem to be the predicting factors for the developmental rate of a brain function in children with history of prematurity. Further investigations are necessary to determine perinatal factors that can affect the modified visual system function in preterm born children.

    Investigated the relationship between poverty and parenting in a sample of low birth weight (poverty levels, poor families scored lower on the HOME inventory (used to measure the caregiving environment) than nonpoor families. A regression model including poverty, race, site, and representative environmental, maternal, and child variables accounted for 60% of variance in total HOME scores. Poverty and maternal IQ had significant and independent effects on HOME scores, whereas maternal distress accounted for little of the variance. In a LBWPT sample, our results find a strong relationship between parenting and poverty, suggest a modest role for maternal psychological distress in this relationship, and indicate that the influence of poverty likely extends beyond commonly measured environmental, maternal, and child factors.

    We aimed to evaluate the efficacy of intravenous administration of recombinant activated factor VIIa (rFVIIa) for acute pulmonary hemorrhage treatment in very-low-birth-weight (VLBW) premature infants. This study was carried out retrospectively in premature infants with pulmonary hemorrhage that were ≤30 weeks gestational age or premature infants with pulmonary hemorrhage who were hospitalized in our neonatal intensive care unit between 01 January 2013 and 31 December 2015 were evaluated. Group 1 (n = 21) received rFVIIa support within the first 30 min of pulmonary hemorrhage plus conventional treatment, while Group 2 (n = 21) received conventional treatment only. The number of patients whose pulmonary hemorrhage was stopped within the first 2 h was significantly higher in Group 1 than Group 2 (n = 14 vs n = 4; p = 0.002). After pulmonary hemorrhage, hemoglobin values of Group 1 were higher than Group 2 (11.12 ± 1.06 vs 10.14 ± 1.59 g/dL; p = 0.024).

    Full Text Available Plasmodium vivax is the most prevalent malaria species in the American region. Brazil accounts for the higher number of the malaria cases reported in pregnant women in the Americas. This study aims to describe the characteristics of pregnant women with malaria in an endemic area of the Brazilian Amazon and the risk factors associated with prematurity and low birth weight (LBW.Between December 2005 and March 2008, 503 pregnant women with malaria that attended a tertiary health centre were enrolled and followed up until delivery and reported a total of 1016 malaria episodes. More than half of study women (54% were between 20-29 years old, and almost a third were adolescents. The prevalence of anaemia at enrolment was 59%. Most women (286/503 reported more than one malaria episode and most malaria episodes (84.5%, 846/1001 were due to P. vivax infection. Among women with only P. vivax malaria, the risk of preterm birth and low birth weight decreased in multigravidae (OR, 0.36 [95% CI, 0.16-0.82]; p = 0.015 and OR 0.24 [95% CI, 0.10-0.58]; p = 0.001, respectively. The risk of preterm birth decreased with higher maternal age (OR 0.43 [95% CI, 0.19-0.95]; p = 0.037 and among those women who reported higher antenatal care (ANC attendance (OR, 0.32 [95% CI, 0.15-0.70]; p = 0.005.This study shows that P. vivax is the prevailing species among pregnant women with malaria in the region and shows that vivax clinical malaria may represent harmful consequences for the health of the mother and their offsprings particularly on specific groups such as adolescents, primigravidae and those women with lower ANC attendance.

    It is unclear what the predictive value of very early development of gestures and language is on later language ability in prematurely born very-low-birth-weight (VLBW; birth weight ≤1500g) children. The aim of the present study was to analyse the predictive value of early gestures and a receptive lexicon measured between the ages of 0;9 and 1;3, as well as the predictive value of receptive and expressive language ability at 2;0 for language skills at 5;0 in VLBW children. The subjects were 29 VLBW children and 28 full-term children whose language development has been followed intensively between the ages of 0;9 and 2;0 using the Finnish version of the MacArthur Developmental Inventory and the Reynell Developmental Language Scales (RDLS III). At 5;0, five selected verbal subtests of the Nepsy II test and the Boston Naming Test (BNT) were used to assess children's language skills. For the first time in VLBW children, the development of gestures measured between the ages of 0;9 and 1;3 was shown to correlate significantly and positively with language skills at 5;0. In addition, both receptive and expressive language ability measured at 2;0 correlated significantly and positively with later language skills in both groups. Moreover, according to the hierarchical regression analysis, the receptive language score of the RDLS III at 2;0 was a clear and significant predictor for language skills at 5;0 in both groups. The findings particularly underline the role of early receptive language as a significant predictor for later language ability in VLBW children. The results provide evidence for a continuity between early language development and later language skills. After reading this article, readers will understand the associations between the very early (≤2 years of age) development of gestures and language (i.e. early receptive lexicon, expressive lexicon at 2;0, receptive and expressive language ability at 2;0) and the language skills at 5;0 in prematurely born

    It has been proposed that during human evolution, development of obligate bipedalism, narrow birth canal cross-sectional area and the large brain have forced an adjustment in duration of pregnancy (scaling of gestational age; Plunkett 2011). Children compared to other mammals are born with proportionally small brains (compared to adult brains), suggesting shortening of pregnancy duration during recent evolution. Prevalence of both obstructed delivery and premature birth is still exceptionally high. In near term infants, functional maturity and viability is high, and gene variants predisposing to respiratory distress syndrome (RDS) are rare. Advanced antenatal and neonatal treatment practices during the new era of medicine allowed survival of also very preterm infants (gestation premature birth. Specific genes associating with diseases in preterm infants may also contribute to the susceptibility to preterm birth. Understanding and applying the knowledge of genetic interactions in normal and abnormal perinatal-neonatal development requires large, well-structured population cohorts, studies involving the whole genome and international interdisciplinary collaboration.

  3. The last and first frontier – emerging challenges for HIV treatment and prevention in the first week of life with emphasis on premature and low birth weight infants

    Full Text Available Introduction: There is new emphasis on identifying and treating HIV in the first days of life and also an appreciation that low birth weight (LBW and preterm delivery (PTD frequently accompany HIV-related pregnancy. Even in the absence of HIV, PTD and LBW contribute substantially to neonatal and infant mortality. HIV-exposed and -infected infants with these characteristics have received little attention thus far. As HIV programs expand to meet the 90-90-90 target for ending the HIV pandemic, attention should focus on newborn infants, including those delivered preterm or of LBW. Discussion: In high prevalence settings, infant diagnosis of HIV is usually undertaken after the neonatal period. However, as in utero infection may be diagnosed at birth, earlier initiation of therapy may limit viral replication and prevent early damage. Globally, there is growing awareness that preterm and LBW infants constitute a substantial proportion of births each year. Preterm infants are at high risk for vertical transmission. Feeding difficulties, apnoea of prematurity and vulnerability to sepsis occur commonly. Feeding intolerance, a frequent occurrence, may compromise oral administration of medications. Although there is growing experience with post-exposure prophylaxis for HIV-exposed term newborn infants, there is less experience with preterm and LBW infants. For treatment, there are even fewer options for preterm infants. Only zidovudine has adequate dosing recommendations for treating term and preterm infants and has an intravenous formulation, essential if feeding intolerance occurs. Nevirapine dosing for prevention, but not treatment, is well established for both term and preterm infants.HIV diagnosis at birth is likely to be extremely stressful for new parents, more so if caring for preterm or LBW infants. Programs need to adapt to support the medical and emotional needs of young infants and their parents, where interventions may be lifesaving

    Swimmers can be exposed to high levels of trihalomethanes, byproducts of chlorination disinfection. There are no published studies on the relation between swimming and birth weight. We explored this relation in a large birth cohort, the Avon (England) Longitudinal Study of Parents and Children (ALSPAC), in 1991-1992. Information on the amount of swimming per week during the first 18-20 weeks of pregnancy was available for 11,462 pregnant women. Fifty-nine percent never swam, 31% swam up to 1 hour per week, and 10% swam for longer. We used linear regression to explore the relation between birth weight and the amount of swimming, with adjustment for gestational age, maternal age, parity, maternal education level, ethnicity, housing tenure, drug use, smoking and alcohol consumption. We found little effect of the amount of swimming on birth weight. More highly educated women were more likely to swim compared with less educated women, whereas smokers were less likely to swim compared with nonsmokers. There appears to be no relation between the duration of swimming and birth weight.

    Full Text Available The evaluation of tools to accurately identify low birth weight (LBW and/or premature newborns in resource-limited countries is a research priority. We explored the use of foot length, chest circumference, and mid-upper arm circumference (MUAC measured within 24 h as diagnostic tools for identifying newborns who are LBW, premature, or both; and compared measurements taken at birth with those taken at five days of age.An observational study was undertaken in Hoa Binh Province General Hospital, Vietnam, in ethnic minority newborns. Birth weight, foot length, chest circumference, and MUAC were measured within 24 h of birth and in a subset of 200, were repeated on day five of life. Gestational age was estimated using the New Ballard Score. Receiver Operating Characteristic curves and optimal cut-points (the point with the highest sensitivity and specificity where the sensitivity was at least 0.8 were calculated, for predicting prematurity, LBW, and both. Measurements within 24 h and at five days of life were compared.485 newborns were recruited. Chest circumference and MUAC measured within 24 h of birth were found to be highly predictive of LBW (both yielding area under the curve [AUC] of 0.98, 95% confidence interval [CI] 0.96-0.99, and performed marginally better than foot length (AUC 0.94, 95%CI 0.92-0.96. The optimal cut-points for measurements within 24 h of birth were ≤ 7.4 cm for foot length; ≤ 30.4 cm for chest circumference; and ≤ 9.0 cm for MUAC. There was statistical evidence that anthropometric measurements taken within 24 h of birth were higher than measurements on day five (p<0.02 for all anthropometric measurements but the magnitude of these differences was small (at most 2mm.All measurements taken within 24 h of birth were good predictors of LBW, prematurity and both. Differences in measurements taken within 24 h and on day five were not clinically relevant. Further research will ensure that the application of these measures is

    Full Text Available Infants born preterm are at greater risk than infants born at term for mortality and a variety of health and developmental problems. Complications include acute respiratory, gastrointestinal, immunologic, central nervous system, hearing, and vision problems, as well as longer-term motor, cognitive, visual, hearing, behavioral, social-emotional, health, and growth problems. The birth of a preterm infant can also bring considerable emotional and economic costs to families and have implications for public-sector services, such as health insurance, educational, and other social support systems. The greatest risk of mortality and morbidity is for those infants born at the earliest gestational ages. However, those infants born nearer to term represent the greatest number of infants born preterm and also experience more complications than infants born at term. Preterm birth is a complex cluster of problems with a set of overlapping factors of influence. Its causes may include individual-level behavioral and psychosocial factors, neighborhood characteristics, environmental exposures, medical conditions, infertility treatments, biological factors and genetics. Many of these factors occur in combination, particularly in those who are socioeconomically disadvantaged or who are members of racial and ethnic minority groups. The empirical investigation was carried out to draw correlation between preterm birth and eventuality. This paper deals with various issues related to the premature deliveries from socio-biological perspectives.

    The purpose of this longitudinal qualitative descriptive study was to explore American Indian (AI) mothers’ perceptions of parenting their premature infants over their first year of life in the context of their culture, including the birth and hospitalization experience. A convenience sample of 17 AI mothers and their premature infants were recruited from either a neonatal intensive care unit (NICU) or pediatric clinic in the southeast. Semistructured interviews were conducted at two time points. Through content analytic methods, three broad categories were revealed: descriptions of having a premature infant in the NICU, descriptions of parenting a premature infant, and the influence of Lumbee culture on parenting a premature infant. Certain aspects of AI culture appear to be important in having a premature infant in the NICU and in parenting a premature infant. We recommend that healthcare providers deliver culturally appropriate care that fully supports AI mothers and their premature infants. PMID:25721716

    Full Text Available Background. Low birth weight is the single most important factor that determines the chances of child survival. A recent annual estimation indicated that nearly 8 million infants are born with low birth weight in India. The infant mortality rate is about 20 times greater for all low birth weight babies. Methods. A matched case–control study was conducted on 130 low birth weight babies and 130 controls for 12 months (from August 1, 2007, to July 31, 2008 at the Central Referral Hospital, Tadong, East District of Sikkim, India. Data were analyzed using the Statistical Package for Social Sciences, version 10.0 for Windows. Chi-square test and multiple logistic regression were applied. A P value less than .05 was considered as significant. Results. In the first phase of this study, 711 newborn babies, borne by 680 mothers, were screened at the Central Referral Hospital of Sikkim during the 1-year study period, and the proportion of low birth weight babies was determined to be 130 (18.3%. Conclusion. Multiple logistic regression analysis, conducted in the second phase, revealed that low or middle socioeconomic status, maternal underweight, twin pregnancy, previous history of delivery of low birth weight babies, smoking and consumption of alcohol during pregnancy, and congenital anomalies had independent significant association with low birth weight in this study population.

    Retinopathy of prematurity is an adverse outcome of preterm birth and is a leading cause of childhood blindness. The relationship between the subtypes of preterm birth with retinopathy of prematurity is understudied. To investigate whether there is a difference in the incidence of type 1 or type 2 retinopathy of prematurity in infants with preterm birth resulting from spontaneous preterm labor, a medical indication of preterm birth, or preterm premature rupture of the membranes. A retrospective cohort study was conducted of 827 infants screened for retinopathy of prematurity who were delivered at a single tertiary care center in Colorado. All infants fulfilled the American Academy of Pediatrics 2013 screening criteria for retinopathy of prematurity defined as "infants with a birth weight of ≤1500 g or gestational age of 30 weeks or less (as defined by the attending neonatologist) and selected infants with a birth weight between 1500 and 2000 g or gestational age of >30 weeks with an unstable clinical course, including those requiring cardiorespiratory support and who are believed by their attending pediatrician or neonatologist to be at high risk for retinopathy of prematurity." Two independent reviewers masked to retinopathy of prematurity outcomes determined whether preterm birth resulted from spontaneous preterm labor, medical indication of preterm birth, or preterm premature rupture of the membranes. Discrepancies were resolved by a third reviewer. Data were analyzed with univariate and multivariable logistic regression. In our cohort, the frequency of preterm birth resulting from spontaneous preterm labor, medical indication of preterm birth, or preterm premature rupture of the membranes was 34%, 40%, and 26%, respectively. The mean gestational age (weeks, days) ± SD (range) in the cohort and across the preterm birth subtypes was as follows: entire cohort, 28 weeks, 6 days ± 2 weeks, 3 days (23 weeks, 3 days - 36 weeks, 4 days); spontaneous preterm labor

    Premature birth is associated with poor metabolic health in both sexes, potentially via earlier pubertal timing. We examined the associations of gestational age and premature birth (Premature girls reached puberty about 4 months later than girls with ≥ 41 weeks' gestation (time ratio = 1.04 [95% confidence interval = 1.01-1.06]), adjusted for mother' age of menarche, mother's place of birth, and smoking during pregnancy. Gestational age was not associated with onset of puberty in boys (test for interaction by sex, P Premature birth was not related to earlier onset of puberty; instead, premature girls had later onset of puberty. Thus, the association between premature birth and subsequent cardiovascular risk is probably not mediated through the timing of pubertal onset. It is unclear whether onset, duration, or tempo of puberty is more relevant to the detrimental consequences of early puberty. Further studies investigating intrauterine, infant, and childhood influences on the duration and tempo of puberty may help unravel the early origins of cardiovascular diseases.

    Premature birth rate and low birth weight rate are increasing in industrialized countries including USA and Japan. The Infant mortality rate (IMR) is three times and 50-75 times greater for infants born at 32-36 weeks and Premature birth is heterogeneous in origin and idiopathic in 70% of the cases. Increased utilization of assisted reproductive technology only accounts for a part of the recent trend. Evidence suggests environmental factors play a significant role, and genetic-environmental interaction is plausible. A chronic psychosocial stress of pregnant women has been postulated to be modifying the endocrine milieu thereby influencing pregnancy outcomes. In a preliminary observation in St. Louis, homeless pregnant women with high behavioral and social risks, when accommodated in a shelter home designed for these women, produced significantly less numbers of premature and low birth weight infants as compared with the general population. Furthermore, in a randomized controlled study in Washington DC, psychobehavioral intervention specifically targeting smoking (primary and secondary), intimate partner violence (IPV), and depression among black pregnant women significantly decreased the rate of miscarriage and low birth weight. These reports may have significant implication to the Japanese situation. Increasing number of Japanese women at reproductive age are exposed to smoking, may have underling psychosocial stress and may suffer from subclinical depression and/or from IPV. Detailed epidemiological studies of women before and during the reproductive age with regard to risk factors can lead to an effective intervention strategy against premature birth in Japan.

    Objective To explore the influence of early intervention on physical and intelligent development of premature infants with very low birth weight. Methods Selected 32 premature infants of very lowbirth weight treated in neonatal intensive care unit during November 2011 to October 2012 as the intervention group. To avoid the violation of medical ethics, we select another 32 premature infants with very low birth weight who were born before November 2011and aged between 9 to 15 months as the control group. The intervention group was treated with early intervention, including regular physical development evaluation, neuromotor examination and test of intelligence. The intervention group was followed-up until correction age of 1 year and the control group was only at the year of correction age of 1 year. Results The physical development in the intervention group was better than the control group at the age of 1, the mental development index (MDI) and psychomotor development index (PDI) significantly higher than those of the control group as well. The incidences of low intelligence and cerebral palsy were lower than those of the control group. The differences were statistically significant. Conclusion Early intervention is obviously effective in promoting the physical and intelligent development of very low birth weight premature infants, reducing the incidence of low intelligence and cerebral palsy, and improving the long-term living quality of the survivors. Still, the method centers on family, and therefore, is feasible and effective.

    Full Text Available Introduction: It is a known fact that there is a connection between periodontal disease and certain systemic conditions. Even though there are some contradictory results in the conducted studies, periodontal disease has been accepted as a risk factor affecting the negative terminations of pregnancy in recent years (premature birth [PB], low birth weight. This consideration is associated with a positive correlation between two conditions in some studies. The Hypothesis: Although there is such a relationship between periodontal disease and PB, the linking mechanism has not been explained as presence of the relation cannot reveal the cause-effect relationship. It should be discussed whether or not this positive connection is caused by the fact that periodontal disease is an independent risk factor for PB, or the change (hormonal, inflammatory in the systemic condition in PB cases causes a risk for periodontal disease. Evaluation of the Hypothesis: The fact that in PB cases the changes in steroid hormone levels might increase the incidence and severity of periodontal disease as in pregnancy, or there could be a common risk factor that may cause both cases, has not been revealed yet and should be taken into consideration.

    Objective To analyze the early outcomes of open heart surgery for congenital heart diseases in sixty low birth weight infants and premature infants. Methods Sixty low birth weight infants (body weight < 2 500 g) and premature infants with congenital heart diseases undergoing surgical repair from May 2003 to October 2011 were studied retrospectively in Guangdong Cardiovascular Institute. There were 43 male patients and 17 female patients with their mean gestational age of 33.5±4.1 weeks (ranging from 26 to 42 weeks) and mean age at operation of 24.9±12.5 d (ranging from 4 to 55 d). Among them there were 47 premature infants with their mean birth weight of 1 729.3±522.5 g (ranging from 640 to 2 500 g) and mean weight at operation of 1 953.2±463.6 g(ranging from 650 to 2 712 g). All the patients received preoperative treatment in newborn intensive care unit (NICU) and underwent surgical repair under general anesthesia, including 29 patients without cardiopulmonary bypass (CPB) and 31 patients with CPB . All surviving patients received postoperative monitoring and treatment in NICU, and their postoperative complications and in-hospital death were reported. Results A total of 13 patients died during hospitalization with a total in-hospital mortality of 21.7% (13/60), including 4 intra-operative deaths, 6 early deaths (within 72 h postoperatively) and 3 patients giving up postoperative treatment. CPB time was 121.0±74.7 min, aortic clamp time was 74.8±44. 7 min, and postoperative mechanical ventilation time was (136.9±138.1) h. Thirteen patients underwent delayed sternal closure. Eight patients underwent reexploation for postoperative bleeding. Ten patients had severe pneumonia, 2 patients had pulmonary hypertensive crisis, and 8 patients had low cardiac output syndrome.

    Low birth weight (LBW) is associated with infant morbidity and mortality. This is the first study of LBW in Kansas using vital statistics to determine maternal and health care system factors associated with LBW. Low birth weight. Determine if prenatal care, maternal socio-demographic or medical factors, or insurance status were associated with LBW. Birth certificate data were merged with Medicaid eligibility data and subjected to logistic regression analysis. Of the 37,081 single vaginal births, LBW rates were 5.5% overall, 10.8% for African Americans, and 5% for White Americans. Lacking private insurance was associated with 34% more LBW infants (AOR 1.34; 95% CI 1.13-1.58), increased comorbidity, and late or less prenatal care. Low birth weight was associated with maternal medical comorbidity and with previous adverse birth outcomes. Insurance status, prenatal care, and maternal health during pregnancy are associated with LBW. Private insurance was consistently associated with more prenatal care and better outcomes. This study has important implications regarding health care reform.

    Autism spectrum disorder (ASD) is common, life-long in nature, and can be very debilitating. Thus, an intensive search is on to identify the potential risk factors for the disorder. Premature birth has been identified as one potential factor that could influence potential symptoms of ASD. The sample for this study consisted of 1655 at risk children for developmental delays who were 17-37 months of age. Participants were divided into those diagnosed with ASD (n = 916) and children with atypical development only (n = 739). Premature births were almost twice as common for the atypical development group versus the ASD group. Implications of these data are discussed.

    The purpose of this study was to examine the effects of music on selected stress behaviors, weight, caloric and formula intake, and length of hospital stay. Subjects were 52 preterm and low birth weight newborns in a newborn intensive care unit (NBICU) who were in stable condition and restricted to isolettes. Subjects in the experimental and control groups were matched for equivalency based on sex, birth weight, and diagnostic criticality. Eleven males and 15 females were assigned to the control group and received routine auditory stimulation. The experimental group of 11 males and 15 females received music stimulation, which consisted of approximately 60 minutes of tape recorded vocal music, including lullabies and children's music, and routine auditory stimulation. Thirty-minute segments of the recording were played alternatively with 30 minutes of routine auditory stimulation three times daily. Exposure to music stimulation occurred only during the infants' stay in the NBICU. Results suggest music stimulation may have significantly reduced initial weight loss, increased daily average weight, increased formula and caloric intake, significantly reduced length of the NBICU and total hospital stays, and significantly reduced the daily group mean of stress behaviors for the experimental group. Data analyses suggest the length of hospital stay may be correlated with the amount of stress experienced by the neonate and not with weight gains. Theoretical and practical aspects of these results are discussed.

  6. Perspectives in the prevention of premature birth.

    2004-11-15

    Obstetric and neonatal interventions have improved the survival of preterm infants, but there has not been an equivalent reduction in long-term neurological disability. Thus, some effort must be invested in finding ways of preventing preterm birth. Numerous programmes have been promoted to address the matter of how the frequency of preterm birth could be prevented. Most interventions intended to prevent preterm labour do not have the desired effect, except for antibiotic treatment in cases of asymptomatic bacteriuria or bacterial vaginosis and progesterone administered prophylactically in high-risk women. Tocolytic drugs appear to delay delivery long enough for successful administration of corticosteroids in women in preterm labour, but without decreasing the risk of preterm birth. Some authors promote public health approaches that address all risk factors and affect the entire population of pregnant women, given that prevention programmes directed only at high-risk women have had little effect in preventing preterm births. However, the lack of progress in reducing the frequency of preterm births is also due to our limited understanding of the aetiology of preterm delivery. Although there is growing evidence that infection and neuroendocrine processes are involved, progress has remained slow. Recently, the hypothesis of a genetic predisposition to preterm delivery has been set up. Additional research exploring the pathophysiology of preterm labour is obviously needed, which will hopefully lead to the development of new therapeutic approaches.

    Objective The objective of this study was to explore the potential of the Infant/Toddler Sensory Profile (ITSP) as a screening tool for autism spectrum disorders (ASD) in prematurely born children. Methods Parents of 157 children with birth weights tools subsequently underwent clinical examination including the Autism Diagnostic Observation Schedule. Results We used classification trees to answer the question whether ITSP (or some of its subscales) could be combined with the M-CHAT and/or the CSBS-DP-ITC or its subscales into an effective ASD screening tool. Using the CSBS-DP-ITC, overall score, and the Sensation Seeking subscale of the ITSP, we obtained a screening tool that was able to identify all of the ASD children in our sample (confirmed by cross-validation). The proposed screening tool is scored as follows: 1) if the overall CSBS-DP-ITC value is <45.5, then the screening is positive; 2) if the overall CSBS-DP-ITC value is ≥45.5 and the z-score of the Sensation Seeking subscale of ITSP is ≥1.54, then the screening is positive; 3) otherwise, the screening is negative. Conclusion The use of CSBS-DP-ITC in combination with the Sensation Seeking subscale of the ITSP improved the accuracy of autism screening in preterm children. PMID:28182143

  12. BIRTH WEIGHT : A COMMUNITY PERSPECTIVE

    Full Text Available India has a dubious distinction of belonging to the top bracket of countries with a very high under-5 Mortality Rate (U5MR of above 96/1000 live births. The U5MR considered the single most significant basic indicator of health status of a community, is proportional to the Infant Mortality Rate (IMR which in turn is contributed to directly and indirectly by the incidence of low Birth Weight (LB W.About 25 million LB W are born each year consisting 17% of all live births,nearly 95% of them in developing countries. About 26% of newborns are LBW in India, and indeed over 16% in those countries with very high U5MR.Both preterm and small-for-dates almost equally make up this category of vulnerable infants predisposed to asphyxia, feeding problems, anemia and growth failure.Considering the close relationship of birth weight with perinatal and infant morbidity as well as mortality, it is crucial to identify the liigh risk groups of low birth weight babies as early as possible.Unfortunately, in a community where 80% of newborns never get to have their weight measured, this itself is a tall order. In our society, the cry of the newborn is greeted with anxious queries about the sex of the baby and not his well­being and potential for healthy survival. The basic concept of the importance of birth weight is missing even among educated families. Indeed, it is as if the weighing machine has no place in the requirements at childbirth. In the absence of this basic facility, field workers and TBAs must report to other means to identify babies at risk. Mid-arm circumference, thigh circumference, foot length, and skin-fold thickness etc. are measurements that have been correlated satisfactorily with the baby’s weight. Simple tools like coloured strips have been developed and these show promise of applicability in field situation for identification of LB W by TBAs for early referral.

    To identify the meanings attributed by mothers to hypertensive disorders of pregnancy (HDPs) and their consequences, such as premature birth and hospitalization of the infant in the neonatal intensive care unit (NICU). A qualitative study, based on the Central Nucleus Theory, with 70 women who had hypertensive disorders of pregnancy and preterm delivery. We used the technique of free word association (FWAT) with three stimuli: high blood pressure during pregnancy, prematurity and NICU. We obtained 1007 evocations, distributed as follows: high blood pressure during pregnancy (335) prematurity (333) and NICU (339). These constituted three thematic units: representation of HDPs, prematurity and the NICU. The categories death and negative aspects were inherent to the three units analyzed, followed by coping strategies and needs for care present in HDPs and prematurity. The study had death as its central nucleus, and highlighted the subjective aspects present in the high risk pregnancy and postpartum cycle. It is hoped that this research will contribute to qualifying nursing care for women confronting the problem of HDPs, so that they can cope with less impacts from the adverse effects of high risk pregnancy and birth.

    Prematurely born individuals have an increased risk for long-term neurocognitive impairments. In animal models, development of the cholinergic basal forebrain (cBF) is selectively vulnerable to adverse effects of perinatal stressors, and impaired cBF integrity results in lasting cognitive deficits. We hypothesized that cBF integrity is impaired in prematurely born individuals and mediates adult cognitive impairments associated with prematurity. We used magnetic resonance imaging-based volumetric assessments of a cytoarchitectonically defined cBF region of interest to determine differences in cBF integrity between 99 adults who were born very preterm and/or with very low birth weight and 106 term-born control subjects from the same birth cohort. Magnetic resonance imaging-derived cBF volumes were studied in relation to neonatal clinical complications after delivery and intelligence measures (IQ) in adulthood. In adults who were born very preterm and/or with very low birth weight, cBF volumes were significantly reduced compared with term-born adults (-4.5% [F1,202 = 11.82, p = .001]). Lower cBF volume in adults who were born very preterm and/or with very low birth weight was specifically associated with both neonatal complications (rpart,92 = -.35, p premature birth and links neonatal complications with long-term cognitive outcome. Data suggest that cholinergic system abnormalities may play a relevant role for long-term neurocognitive impairments associated with premature delivery.

    Full Text Available The article examines the modern data on the importance of breast milk in nursing premature babies. It is shown that the amount of breast milk in women, who gave birth prematurely, decreases rapidly, especially when it is impossible to get a baby latched on to the breast. There is a negative correlation between gestational age and duration of lactation. According to the opinion of both doctors and the majority of mothers, pumping out breast milk and using it in feeding a premature baby is an important psychological and physiological factor linking a mother and a child at the intensive care unit. Individual breast milk banks are a new safe and effective method for long-term keeping of breast milk.

    Full Text Available Delivery before 37th week of gestation is defined as preterm, independently of body mass of babies, according to the World Health Organization. Premature birth is the current problem in the world due to the high risk of neonatal morbidity and mortality and incompletely clear etiology. In our country the frequency of preterm delivery is 6%. We have retrospectively analyzed early deliveries in Health Center Kosovska Mitrovica in the period from 2009 to 2013. In this five-year period, there were totaly 3398 deliveries, of which 148 or 4.35 % were preterm delivery. The aim of this study was to investigate the incidence of premature birth in the five-year period in relation to: the total number of births in a given period, the age of the patients, the manner of completion of delivery, gestational week of pregnancy, parity and the most common causes that led to the PTP. In the analysis we have included the body weight and Apgar score of premature infants. We have used protocols of births, maternal history of disease, neonatal protocols and lists of newborns. Most of them were multiparas (41.2 %,56.7 % of pregnant women were aged of 21-30 years and pregnancy in 79.9 % of cases ended with 33 to 37 ng. Vaginal deliveries were completed in 84.4% of premature births, and caesarean in 15.6%. Twin pregnancies with preterm deliveries were represented in 10.2%. The most common weight of premature infants ranged from 2000 to 2500 grams (48.6 %. The most common causes that led to the PTP were PPROM (22.9 %, unknown causes (27. 1 %, multiple pregnancy (18.2 %, genital infection (8.7 %, cervical incompetence (6.7 %, IUGR (5.4%, PIH (4.2%, placental abruption and placenta previa (2.1 % and other (4.7% .

    Preterm birth is the second leading cause of death in children under the age of five years worldwide, but the etiology of many cases remains enigmatic. The dogma that the fetus resides in a sterile environment is being challenged by recent findings and the question has arisen whether microbes that colonize the fetus may be related to preterm birth. It has been posited that meconium reflects the in-utero microbial environment. In this study, correlations between fetal intestinal bacteria from meconium and gestational age were examined in order to suggest underlying mechanisms that may contribute to preterm birth. Meconium from 52 infants ranging in gestational age from 23 to 41 weeks was collected, the DNA extracted, and 16S rRNA analysis performed. Resulting taxa of microbes were correlated to clinical variables and also compared to previous studies of amniotic fluid and other human microbiome niches. Increased detection of bacterial 16S rRNA in meconium of infants of premature birth. This provides the first evidence to support the hypothesis that the fetal intestinal microbiome derived from swallowed amniotic fluid may be involved in the inflammatory response that leads to premature birth.

    BACKGROUND: Low birth weight is an important risk factor for hypertension and unfavorable prognoses of a number of renal diseases. It is also associated with reduced kidney size and nephron number. A differentiation between the effects of low birth weight versus being born premature or small...... growth-retarded infants (Premature children had smaller kidneys compared to mature at all ages (0 months, P= 0.001; 3 months, P= 0.007; and 18 months, P= 0.042), without any significant catch-up with age...... growth in response to formula feeding. CONCLUSION: Being small for gestational age is associated with small kidneys at birth and impaired kidney growth in early childhood.

    To study the effects of premature birth on the development of rat retinal vasculature. Experimental study. Sixty pregnant Sprague-Dawley rats were divided into four groups: bacterial lipopolysaccharide-induced preterm group (LPS group), RU-486 induced preterm group (RP group), cesarean section induced preterm group (CP group), and the normal delivery rats as the control group. The weight of rats from each group was recorded until postnatal day 21. On postnatal day 4, 7, 10 and 14 (P4, P7, P10 and P14), the retina of right eye was dissected and whole-mounted. Each premature group was divided into two subgroups based on the number of rats in each litter, the small subgroup (6-8 rats per litter, group 1) and the large subgroup (14-18 rats per litter, group 2). The development of retinal vascularization process was observed on P4, P7 and P10 (n = 6).Independent t test, one-way ANOVA and LSD-t test were used to analyzed the results. The weight of premature rats in LPS, CP and RP groups was significantly lower than that in the normal group within postnatal 21 days (LSD-t test: all P premature rats have lower weight and much slower rate of early retinal vascularization, as compared with the normal rats. Furthermore, in the premature rats, the proportion of retinal vascularization in larger litters is less than that in smaller litters. These results indicate that premature birth and larger litter size have effects on the development of rat retinal vasculature.

    Previous studies have produced conflicting results with regard to the association between birth weight and developmental stuttering. This study sought to determine whether birth weight was associated with childhood and/or adolescent stuttering in three British birth cohort samples. Logistic regression analyses were carried out on data from the Millenium Cohort Study (MCS), British Cohort Study (BCS70) and National Child Development Study (NCDS), whose initial cohorts comprised over 56,000 individuals. The outcome variables were parent-reported stuttering in childhood or in adolescence; the predictors, based on prior research, were birth weight, sex, multiple birth status, vocabulary score and mother's level of education. Birth weight was analysed both as a categorical variable (low birth weight, stuttering during childhood (age 3, 5 and 7 and MCS, BCS70 and NCDS, respectively) or at age 16, when developmental stuttering is likely to be persistent. None of the multivariate analyses revealed an association between birth weight and parent-reported stuttering. Sex was a significant predictor of stuttering in all the analyses, with males 1.6-3.6 times more likely than females to stutter. Our results suggest that birth weight is not a clinically useful predictor of childhood or persistent stuttering. Copyright © 2013 Elsevier Inc. All rights reserved.

Left undisturbed, elephants reproduce well and in approximately even numbers in the wild. We report an excess of males are born and substantial juvenile mortality occurs, perinatally, in captivity. Studbook data on captive births (CB, n=487) and premature deaths (PD, 6 months with maternal insufficient milk production, natural hazards and accidents being the main causes. European Asian and Myanmar elephants PD was biased towards males (0.71, P=0.024 and 0.56, P<0.001, respectively). The skewed birth sex ratio and high juvenile mortality hinder efforts to help captive populations become self-sustaining. Efforts should be invested to identify the mechanism behind these trends and seek solutions for them.

    We have investigated the effects of iodine (I) intake on urinary I excretion in preterm (PT) babies up to 2 months after birth and its effect on serum T4, free T4 (FT4), T3, TSH, and thyroglobulin (Tg) levels compared to those in term (T) newborns. Very premature and very sick infants were in negative I balance for the first weeks after birth. Later, these same infants, as well as the other PT and T newborns, were in positive balance; 75- 80% of the ingested I was not accounted for in the urine. The urinary I levels of PT and T neonates cannot be equated to their I intakes. T4, FT4, and T3 levels in PT and T neonates increased with postmenstrual age, whereas Tg decreased and TSH did not change. Serum FT4, T3, Tg, and TSH levels in PT neonates were affected negatively, independently from age, by a low I intake. PT birth also affected T4, FT4, and Tg negatively, independently from I intake and postmenstrual age, for at least 6-8 weeks after birth. Care should be taken to avoid I deficiency in PT neonates. However, even when I intake is adequate, PT newborns are hypothyroxinemic compared to T babies during an important period of brain development. This suggests the possible convenience of interventions that might mimic the intrauterine hormone environment and accelerate maturation.

    The objective of this paper is to analyse temporal birth weight variation, its relationship to the frequency of premature births in Portugal, and the influence of native and immigrant mothers' characteristics as well as to determine the possible existence of a pattern of temporal change in birth weight in the Iberian Peninsula as a whole. Individual mother-child data from the Portuguese National Institute of Statistics regarding live births (N = 2,661,542) permitted an analysis, for the first time, of weight at birth in Portugal from a bio-demographic perspective. The results obtained show that from 1988 to 2011 there was a gradual decline in the average weight at birth in Portugal that may be related to shifts in the duration of gestation. An initial rapid decline in the relative frequency of post-term births took place, followed by small variations from 1995 on. Logistic regressions indicated a pattern unaffected by maternal origin or the sex of the newborn. With regard to weeks of gestation, the odds values obtained were < 1 when the reference category was < 28 weeks. For this factor, no significant differences were found in relation to the mother's origin. Portuguese mothers over 35 years were associated with a higher incidence of low birth weight. Regardless of maternal origin, being a newborn of parity 1, and with the mother not in a couple, resulted in unfavourable outcomes with regard to low birth weight. On the other hand, long gestation periods and having secondary or university education constituted a protective factor.

    Full Text Available Realizou-se revisão sistemática sobre o consumo de cafeína em gestantes na ocorrência de baixo peso ao nascer e prematuridade, enfocando métodos para quantificação deste consumo e confundimentos controlados na análise. A revisão consistiu na busca de artigos publicados de 1996 a 2006 nas bases MEDLINE, LILACS e PubMed, utilizando-se as palavras-chave: "caffeine", "coffee", "low birth weight", "birth weight", "preterm", "premature" e "prematurity". Dez artigos foram selecionados. Os métodos utilizados para quantificar o consumo de cafeína foram: questionário de freqüência alimentar semiquantitativo - da dieta ou apenas de produtos cafeinados, sendo um do tipo auto-aplicado; recordatório alimentar; perguntas sobre tipo e modo de preparo; análise de amostras; e dosagens urinária e plasmática. Em três estudos revisados, o consumo elevado de cafeína associou-se com baixo peso ao nascer e/ou prematuridade. Contradições nos achados devem-se a dificuldades na mensuração do consumo de cafeína; às fontes abordadas; a variações no preparo e na quantidade consumida; e ao tamanho amostral.

    A large body of literature suggests an inverse relationship between birth weight and blood pressure in children, adolescents and adults. The most persistent findings have been observed in children with a history of low birth weight or intrauterine growth restriction, while a large number of studies carried out in populations with normally distributed birth weight have shown conflicting results. A recently reported strong direct association between high birth weight and blood pressure, and the significant positive effect of postnatal growth on blood pressure suggests that the fetal origins of adult disease hypothesis should be expanded to include the role of excessive fetal and postnatal growth. In this paper, we review recent studies on the relationship between birth weight and blood pressure in childhood, with a focus on confounding variables that may explain the conflicting results of published work in this field.

    A case-control study was made in Gunma Prefecture of 1,390 mothers of babies born weighing 2,500 grams or less and an equal number of mothers of 3,000-up to-4,000 gram babies matched by place and month of birth. A correlation was found between low-birth-weight babies and maternal age, stature, menstrual history and past history. The mother's occupation, educational career, smoking habits, amount of sleep each day, date of issue of the Mother's Handbook and the number of the periodical health examinations received can be listed as socio-medical factors. Bleeding and lower abdominal pain during pregnancy, anemia and toxemia of pregnancy are found as prenatal factors. Low-birth-weight babies are found to be correlated with multiple pregnancy, breech presentation, placenta previa and premature separation of the placenta, also.

    A premature birth can cause parental stress, anxiety and uncertainty. This study illustrates the long-term consequences of a preterm birth for family life. Retrospective study by questionnaire. Parents of 959 children, who were born in 1983 with a gestational age of less than 32 weeks or a birth weight of less than 1500 grams, were approached when their children turned 19 years old. We investigated various aspects of their family lives by means of a written questionnaire. We received completed questionnaires back from 595 parents (62%). The divorce rate was higher in families with a disabled child (26 vs. 14%). Working mothers (n = 257) and fathers (n = 506) experienced negative consequences in their workplace (36% and 2%, respectively). The risk factor was having a handicapped child. Financial problems were present in 11% of the families during the first year and 4% still experienced financial problems after 19 years; risk factors were a handicap, male gender and a low social-economic status (SES) of the parents. Of the respondents, 26% had observed a decrease in social activities and friends during the first year and 15% felt that family and friends provided insufficient support during this year. After 19 years, 4% of the respondents still experienced a negative influence on their social lives. Risk factors were a handicap, normal birth weight (no dysmaturity), male gender and low SES. 28% of parents expressed that during the first year having a preterm child was emotional challenging or difficult to accept. After 19 years, 3% still expressed an unfavourable effect of the preterm birth. Risk factors were handicap, dysmaturity and male gender. A premature birth has a great impact on the family, especially when the child has a handicap.

    Full Text Available In 17 hospitals, 13123 new births were born during 1989 in Tehran. Some well-trained personnel observed the events, filling the required questionnaires, interviewing, and collecting necessary information. Among them 730 newborns was low birth weight (less than 2500 grams which was considered as cases. Immediately after each case was born, two normal newborn were randomly selected as controls. So at the end of data collection, a total of 1460 births were considered controls. In a case-control study the effect of some risk factors during pregnancy of mothers on birth weight and death rate of newborn during first 4 weeks of their life were fully investigated. Some of the findings are as follows: The past history of miscarriages will decrease the birth weight of the newborn and thereby will increase the death rate in the first 28 days of their life. In this respect the difference between case and control was highly significant. Other variables like past history of premature birth, chronic diseases, hemorrhage and severe vomiting showed the same results.

    Birth characteristics, including weight and gestational age, may be associated with risk of Barrett's esophagus (BE), the only known precursor for esophageal adenocarcinoma; however, data are limited. To examine associations between various birth characteristics and BE, and whether these associations are mediated by known risk factors for BE. Data were obtained from a cross-sectional study among eligible Veterans Affairs patients scheduled for an upper endoscopy, and a sample identified from primary care clinics. Participants underwent an esophagogastroduodenoscopy and completed a survey that captured information on sociodemographic and clinical factors, as well as birth information. We compared 263 patients with histologically confirmed BE to 1416 controls without BE on endoscopy. Odds ratios (ORs) and 95 % confidence intervals (CIs) were calculated using multivariate logistic regression. Premature birth was independently associated with risk of BE after adjusted by age, sex, race, and other birth characteristics (OR 3.28, 95 % CI 1.22-8.79). On the other hand, large for gestational age was inversely associated with risk of BE (OR 0.46, 95 % CI 0.21-0.98). These effects were stronger for patients with long-segment BE than with short-segment BE. The associations were not mediated by gastroesophageal reflux disease symptoms, use of proton pump inhibitors, Helicobacter Pylori infection, waist-hip-ratio, height or the presence of hiatus hernia. Premature birth and large for gestational age may be associated with risk of BE in adults. These associations do not appear to be mediated through known risk factors for BE; however, additional studies are required to confirm our findings.

    Full Text Available Background In several provinces of Eastern Indonesia, the majority of births take place at home (60% and are assisted by traditional birth attendants. Most of these newborns do not have their birth weight recorded, due to lack of available weighing scales or lack of skill to perform the measurement, especially in rural areas. As such, an early identification of low birth weight cases is needed to prevent infant morbidity and mortality. Objective To assess anthropometric measurements including calf, chest, and head circumferences as a method of choice for detecting low birth weight, as substitute for actual weighing. Methods This cross-sectional study was performed at Banjar Baru, South Kalimantan, Indonesia, from January to March 2012. Subjects were full term, singleton, and live-born infants during the study period, and obtained from private clinics by a purposive sampling procedure. Calf, chest, and head circumferences were measured to identify the most suitable substitute for birth weight using Pearson’s correlation, ROC, sensitivity, and specificity. Results In this study, a correlation was shown between birth weight and all anthropometric measurements. Optimal calf, chest, and head circumference cutoff points to identify low birth weight infants were 10.3 cm, 30.7 cm, and 31.2 cm, respectively. The area under the curves (AUC showed good accuracy for all measurement types. Calf circumference had the closest estimated true prevalence to the true prevalence (8� .52% and 8.6%, respec-.52% respec- 52% respec-%8.6%, respec-.6%, 6%, respec-%, respectively compared to the other measurement types. Conclusion Calf circumference is the most suitable measurement as a substitute for birth weight, due to its estimated true prevalence. [Paediatr Indones. 2013;53:177-80.].

    Premature birth is a serious problem of public health around the world owing to the high frequency of complications and perinatal losses. According to the WHO recommendations by gestation terms the premature birth divides into: super early premature birth (SEPB) in the term of 22-27 weeks, early PB in the term of 28-33 weeks and PB in the term of 34-37 weeks. Preterm born infants make 85%, and in the neonatal mortality structure make more than 55%. It is necessary to consider that in recent years the number of women in the premature birth development risk group has increased, to which patients with a uterus scar, extragenital pathology, supporting reproductive technology treatment pregnancy are related.

  9. Children born with very low birth weight show difficulties with sustained attention but not response inhibition.

    Children born with very low birth weight perform poorly on executive function and attention measures. Any difficulties with sustained attention may underpin impairments in performance on tasks measuring higher order cognitive control. Previous sustained attention research in very low birth weight cohorts has used tasks that involve arousing stimuli, potentially spoiling the measure of sustained attention. The aim of this study was to compare the performance of very low birth weight and normal birth weight children on a well-controlled task of sustained attention. The Fixed and Random versions of the Sustained Attention to Response Task were given to 17 very low birth weight and 18 normal birth weight children. The very low birth weight group performed the Fixed and Random Sustained Attention to Response Tasks in a similar manner as the normal birth weight group on all measures except for the omission error and Slow Frequency Area under the Spectra variables on the Fixed Sustained Attention to Response Task. These measures index lapses in sustained attention that may be underpinned by declining arousal. The very low birth weight group showed no response inhibition deficits. Omission errors and slow-timescale response-time variability on predictable tasks may thus present sensitive indices of difficulties with sustained attention and arousal associated with premature birth and low birth weight.

    Background Infantile colic is a condition of unknown origin characterized by paroxysms of crying during the first months of life. A few studies have identified low birth weight (BW) as a risk factor among infants born at term, while the association between gestational age (GA) and infantile colic......, low BW was associated with infantile colic only in infants born at term (gestational weeks 37-41), but not in pre- or post-term infants. Conclusion The results indicate that low birth weight and preterm birth are independently associated with infantile colic. After adjusting for gestational age, low...... birth weight increased the risk of infantile colic in children born at term (gestational weeks 37-41)....

    Prematurity and poor weight gaining are important causes for neonatal hospitalization. The present study aimed to investigate the role of medium-chain triglyceride (MCT) oil via massage therapy as a supplementary nutritional method on the weight gain of Neonatal Intensive Care Units (NICU)-hospitalized neonates. This randomized clinical trial performed among 121 stable premature neonates hospitalized in the NICU of Qaem Educational Hospital, Mashhad, Iran. They were randomly divided into three groups: oil-massage, massage alone and control groups. These groups were compared on the basis of weight gain during a one-week interval. The three groups were matched for sex, mean gestational age, birth weight, head circumference, delivery, and feeding type (P>0.05). The mean weight gain on the 7th day in the oil massage group was 105±1.3gr and 52±0.1gr in the massage group; whereas 54±1.3gr weight loss was observed in the control group. Significant differences were observed between the oil-massage group and the other two groups, respectively (P=0.002 and P=0.000). The findings of this study suggest that transcutaneous feeding with MCT oil massage therapy in premature neonates can result in accelerated weight gain in this age group with no risk of NEC.

    Background More than half of the world's population lives in urban environments. Due to urban related factors (e.g. higher air pollution), urban residents may face higher risk of adverse health outcomes, while access to green space could benefit health. Purpose We explored associations between urban and green land-use and birth weight. Methods Connecticut, U.S., birth certificate data (2000-2006) were acquired (n=239,811), and land-use data were obtained from the National Land Cover Database. We focused on three land-uses; urban space, urban open space, and green space (i.e. forest, shrub, herbaceous, and cultivated land). We estimated fractions of greenness and urbanicity within 250 m from residence. A linear mixed effects model was conducted for birth weight and a logistic mixed effects model for low birth weight (LBW) and small for gestational age (SGA). Results An interquartile range (IQR) increment in the fraction of green space within 250 m of residence was associated with 3.2g (95% Confidence Interval [0.4, 6.0]) higher birth weight. Similarly, an IQR increase in green space was associated with 7.6% [2.6, 12.4] decreased risk of LBW. Exposure to urban space was negatively correlated with green space (Pearson correlation = −0.88), and it showed negative association with birth outcomes. Results were generally robust with different buffer sizes and controlling for fine particles (PM2.5) and traffic. Conclusions We found protective associations by green space on birth outcomes. Increasing green space and/or reducing urban space (e.g. the greening of city environments) may reduce the risk of adverse birth outcomes such as LBW and SGA. Populations living in urban environments will grow in the next half century, and allocation of green space among urban areas may play a critical role for public health in urban planning.

    To compare regional cerebellar microstructure, as measured by diffusion tensor imaging (DTI), between preterm infants at term-equivalent age and healthy term-born control neonates, and to explore associations between DTI findings and clinical risk factors. In this case-control study, DTI studies were performed in 73 premature infants born ≤32 weeks and ≤1500 g birth weight and 73 full-term-born controls from healthy pregnancies. Using a region of interest approach, fractional anisotropy (FA) and mean diffusivity (MD) were extracted in 7 cerebellar regions including the anterior vermis, the right/left superior cerebellar peduncles, the middle cerebellar peduncle, and the dentate nuclei. To validate further our DTI measurements, we measured FA and MD in the genu of the corpus callosum and splenium. FA and MD were compared between groups using analyses of multiple linear regression models. Preterm infants at term-equivalent age presented with higher FA in the dentate nuclei (premature birth are associated with altered cerebellar microstructural organization when compared with term-born control infants.

    Premature infants exhibit neurodevelopmental delay and reduced growth of the cerebral cortex. However, the underlying mechanisms have remained elusive. Therefore, we hypothesized that neurogenesis in the ventricular and subventricular zones of the cerebral cortex would continue in the third trimester of pregnancy and that preterm birth would suppress neurogenesis. To test our hypotheses, we evaluated autopsy materials from human fetuses and preterm infants of 16-35 gestational weeks (gw). We noted that both cycling and noncycling Sox2(+) radial glial cells and Tbr2(+) intermediate progenitors were abundant in human preterm infants until 28 gw. However, their densities consistently decreased from 16 through 28 gw. To determine the effect of premature birth on neurogenesis, we used a rabbit model and compared preterm [embryonic day 29 (E29), 3 d old] and term (E32, premature infants, preterm birth suppresses neurogenesis, and hypoxia-mimetic agents might restore neurogenesis, enhance cortical growth, and improve neurodevelopmental outcome of premature infants.

    Premature birth due to cervical incompetence is a major obstacle of perinatal medicine. While measures of prevention have been investigated, the mother should be transferred to a perinatal centre when delivery prematurity, IUGR,and maternal disease was performed to evaluate the relation of prolongation of gestation to the level of care. Admissions with imminent premature birth due to cervical incompetence were identified in 6 892 cases. Overall prolongation until birth was 9.6 days. When the cervical incompetence was premature newborns the organisation of perinatal care should aim at intrauterine transfer to a specialised perinatal unit.A precondition is a health system with an adequate structure of perinatal centres within 30 k min the case of obstetrical emergencies

    To investigate the impact of premature birth on long term cardio-cerebral vascular events of puerpera. Ambispective cohort study method was used and 3 659 pregnant women giving birth during October 1976 to December 2008 at Kailuan medical group were included and divided into premature birth (PTB) group (n = 226) and non-PTB (NPTB) group (n = 3 433) by the history of PTB. Incidence of cardio-cerebral vascular events (myocardial infarction, cerebral infarction and cerebral hemorrhage) was obtained during follow-up. Multivariable Cox proportional hazards regression models was used to assess the relative risk of cardio-cerebral vascular events. (1) The childbearing age, proportion of pregnancy-induced hypertension, systolic blood pressure and diastolic blood pressure before delivery were significantly higher while weight and height of newborn were significantly less in PTB group than in NPTB group (P < 0.05 or 0.01). (2) There were 71 cardio-cerebral vascular events during the follow-up of (15.19 ± 7.75) years. In PTB group, the incidence of cardio-cerebral vascular events and myocardial infarction was 3.23/1 000 person-years and 2.05/1 000 person-years, respectively, while the corresponding incidence was 1.15/1 000 person-years and 0.42/1 000 person-years, respectively in NPTB group (all P < 0.05). After adjustment for other traditional cardiovascular risk factors, the risk of total cardio-cerebral vascular events, myocardial infarction in PTB group was 2.03 fold (95% CI: 1.02-4.04, P = 0.002) and 3.11 fold (95% CI: 1.18-8.18, P < 0.001) higher than in NPTB group. PTB is an independent risk factor for total cardio-cerebral vascular events, especially myocardial infarction of puerpera.

    Full Text Available OBJECTIVES: This current study has been conducted to clarify the relationship between the mother's post-traumatic reaction triggered by premature birth and the mother-infant interactions. In this article, the precocious maternal feelings are described. METHODS: A multicenter prospective study was performed in three French hospitals. 100 dyads with 100 very premature infants and their mothers were recruited. Mothers completed, at two different times self-questionnaires of depression/anxiety, trauma and social support. The quality of interactions in the dyads was evaluated. RESULTS: Thirty-nine percent of the mothers obtained a score at HADS suggesting a high risk of depression at the first visit and approximately one-third at visit two. Seventy-five percent of the mothers were at risk of suffering from an anxiety disorder at visit one and half remained so at visit two. A "depressed" score at visits one and two correlated with a hospitalization for a threatened premature labor. We noted a high risk of trauma for 35% of the mothers and high interactional synchrony was observed for approximately two-thirds of the dyads. The mothers' psychological reactions such as depression and anxiety or postnatal depression correlate strongly with the presence of an initial trauma. At visit one and visit two, a high score of satisfaction concerning social support correlates negatively with presence of a trauma. A maternal risk of trauma is more frequent with a C-section delivery. CONCLUSIONS: Mothers' psychological reactions such as depression and anxiety correlate greatly with the presence of an initial trauma. The maternal traumatic reaction linked to premature birth does not correlate with the term at birth, but rather with the weight of the baby. Social support perceived by the mother is correlated with the absence of maternal trauma before returning home, and also seems to inhibit from depressive symptoms from the time of the infant's premature birth.

    Full Text Available Our aim was to investigate whether birth weight in mothers with diabetes mellitus type 1 is higher as compared to nondiabetic controls. Methods. A retrospective study was performed using an existing database covering the region of Flanders, Belgium. Data included the presence of diabetes type 1, hypertension, parity, maternal age, the use artificial reproductive technology, fetal- neonatal death, congenital anomalies, admission to a neonatal intensive care unit, and delivery by Caesarean section or vaginally. Results. In the period studied, 354 women with diabetes type 1 gave birth and were compared with 177.471 controls. Women with type 1 diabetes more often had a maternal age of over 35 years (16.7% versus 12.0%, P=.008, OR 1.46; 95% CI 1.09–1.95. They more frequently suffered hypertension in pregnancy (19.5% versus 4.7%, P<.0001, OR 4.91; 95% CI 3.73–6.44. Perinatal death was significantly higher in the diabetes mellitus group (3.05% versus 0.73%, P<.0001, OR 4.28; 95% CI 2.22–8.01. Caesarean section was performed almost 5 times as frequently in the diabetes versus the control group (OR 4.57; 95% CI 3.70–5.65. Birth weight was significantly higher in diabetic pregnant women from 33 until 38 weeks included, but those reaching 39 weeks and later were not different with control groups. Conclusion. In Belgium, diabetic pregnancy still carries a high risk for fetal and maternal complications; in general birth weight is significantly higher but for those reaching term there is no significant difference in birth weight.

    Although the effects of meteorological factors on the general population health are widely documented, little is known about their influence on human pregnancy and birth. The present study aims at analyzing the influence of the atmospheric conditions on premature births. One hundred and eight nine cases of premature births were included in the study, with a gestational age between 24 to 37 weeks of amenorrhea. Cases with antepartum fetal death and those with uncertain gestational age have been excluded. Daily weather data were obtained using http://www.wunderground.com site. A Pearson's product-moment correlation was run to assess the relationship between weekly preterm birth incidence and the total number of premature births and the mean maximum and minimum temperature (Tmax, Tmin), maximum and minimum average humidity (Umax, Umin), maximum and minimum atmospheric pressure mean (P max, P min), average wind speed and average quantity precipitations, calculated for one calendar week. Approximately 7.7% of all births during the study period occurred before 37 weeks of gestation, the main reason for hospitalization being premature rupture of membranes (45%). The analysis revealed a moderate positive correlation between weekly preterm birth incidence and the average temperature (r=0.306, n=52, p=0.027) and a moderate positive correlation between weekly preterm birth incidence and temperature variation (r=0.307, n=52, p=0.007). Our study found no significant statistic correlation between the humidity variation, pressure variation, and wind speed. The incidence of premature births can be influenced by variations of specific weather factors, especially during the weeks characterized by large fluctuations in temperature. The results obtained might inspire the construction of multicenter studies to investigate more thoroughly the adverse effects of some meteorological factors that can influence the outcomes of human pregnancy.

    To address the hypothesis that maternal uteroplacental insufficiency (UPI) increases severity of retinopathy of prematurity, we developed a composite rat model of UPI and oxygen-fluctuations and removed premature birth as a confounding factor. Timed-pregnant Sprague-Dawley dams underwent bilateral uterine artery ligation or anesthesia (control) at e19.5. Full-term pups developed in room air (RA) or an oxygen-induced retinopathy (OIR) model. Isolectin-stained retinal flat-mounts were analyzed for percent of areas of avascular/total retina (AVA) and of intravitreal neovascular/total retina (IVNV). Pup weights and serum and mRNA of liver and kidney VEGF, IGF-1, and erythropoietin (EPO) were determined. Multivariable mixed effects linear regressions and Pearson correlations were performed using STATA14. Postnatal growth restriction occurred in pups in UPI/RA, but not in UPI/OIR. Weight gain was similar between UPI/OIR and control/OIR pups. AVA was reduced and a trend toward reduced IVNV was seen in UPI/OIR compared to control/OIR. No difference in birth weights of UPI/OIR vs. control/OIR pups occurred. Serum and renal IGF-1 and EPO were significantly increased in UPI/OIR compared to control/OIR pups. In the absence of prematurity, UPI increased angiogenic factors in association with reduced OIR severity, suggesting that ischemia from UPI could yield protective angiogenic effects by offspring.

    Children born preterm are at increased risk for executive dysfunction, which affects learning outcomes. Picture sequencing ability is considered as executive function (EF) that requires skills in working memory and organizing the pictures. Children born preterm might have difficulties in these skills. The present study aimed to develop practical Picture Sequencing test (PS test) and examine the sequencing ability in preterm children comparing with term children. The PS test was developed to assess the child's ability to arrange pictures into a sequence. It consisted of three conditions, which were daily activities, social interaction routines, and feeling expressions. Each story had four cartoon styles cards. The child had to rearrange picture cards into the correct sequence positions. Thirty preterm children aged five to six years with gestational ages of 32 weeks and birth weights of < 1,500 grams, and thirty-five term children matched age, gender child 's education, parental education, and socioeconomic status were performed the PS test. The total scores were compared between the preterm group and the term group. The PS test scores on the daily activities domain of the preterm and term group were 18 and 25 (p = 0.03), respectively. The scores on the social interaction routines domain ofthe preterm and term group were 20 and 28 (p = 0.01) and the scores on the feeling expression domain were 18.5 and25 (p = 0.03), respectively. There was no significant correlation between perinatal complications and the PS test scores. The preterm children with IQs in the average range showed impairment in sequencing ability compared with the term children. The results underline the need for follow-up care with more comprehensive assessment of EF.

    Full Text Available OBJECTIVE To analyze if dietary patterns during the third gestational trimester are associated with birth weight.METHODS Longitudinal study conducted in the cities of Petropolis and Queimados, Rio de Janeiro (RJ, Southeastern Brazil, between 2007 and 2008. We analyzed data from the first and second follow-up wave of a prospective cohort. Food consumption of 1,298 pregnant women was assessed using a semi-quantitative questionnaire about food frequency. Dietary patterns were obtained by exploratory factor analysis, using the Varimax rotation method. We also applied the multivariate linear regression model to estimate the association between food consumption patterns and birth weight.RESULTS Four patterns of consumption – which explain 36.4% of the variability – were identified and divided as follows: (1 prudent pattern (milk, yogurt, cheese, fruit and fresh-fruit juice, cracker, and chicken/beef/fish/liver, which explained 14.9% of the consumption; (2 traditional pattern, consisting of beans, rice, vegetables, breads, butter/margarine and sugar, which explained 8.8% of the variation in consumption; (3 Western pattern (potato/cassava/yams, macaroni, flour/farofa/grits, pizza/hamburger/deep fried pastries, soft drinks/cool drinks and pork/sausages/egg, which accounts for 6.9% of the variance; and (4 snack pattern (sandwich cookie, salty snacks, chocolate, and chocolate drink mix, which explains 5.7% of the consumption variability. The snack dietary pattern was positively associated with birth weight (β = 56.64; p = 0.04 in pregnant adolescents.CONCLUSIONS For pregnant adolescents, the greater the adherence to snack pattern during pregnancy, the greater the baby’s birth weight.

    Full Text Available The present study was conducted to determine some environmental factors affecting birth weight, weaning weight and daily live weight gain of Holstein calves of a livestock facility in Izmir, Turkey. The data on 2091 calves born between the years 2005-2010 were used to assess the relevant parameters. Effects of calving year, calving month, calf gender and the interaction between calving year and calving month on calves’ birth weights were highly significant. The overall mean of birth weights was 39.6±0.15 kg. In addition, effects of calving year, calving month, gender, birth weight, weaning age, calving year x calving month, calving year x gender and calving year x calving month x gender interactions on weaning weight (WW and daily live weight gain (DLWG were highly significant. The overall means of WW and DLWG were respectively found to be 79.7±0.20 kg and 525±2.5 g. A one kilogram increase in birth weight resulted in an increase of 0.89 kg in weaning weight and a decrease of 1.26 g in daily live weight gain. Prenatal temperature-humidity index (THI affected birth weight of calves (R2=0.67. Increasing THI from 50 to 80 resulted in 3.8 kg decrease in birth weight.

    Objective The aim of this study was to investigate the nutritional status of the hospitalized premature infants with birth weight lower than 1 500 g in the different areas in China, and to analyze the related inlfuence factors of extrauterine growth restriction (EUGR). Methods The retrospective survey method was used to collect clinical data of the premature infants with birth weight lower than 1 500 g and hospital stay of more than 2 weeks in 15 hospitals between January 1, 2012 and December 31, 2012. A descriptive analysis was performed for intestinal and parenteral nutrition and weight gain, and the related inlfuence factors of EUGR were analyzed. Results A total of 572 premature infants were selected. The mean gestational age was 30.6±2.0 weeks, and the mean birth weight was 1255.7±164.8 g. The mean enteral feeding starting time after birth was 68.2±85.4 hours, and the mean age to reach oral calorie of 100 kcal/(kg·d) was 29.9±14.1 days. During hospitalization, the mean weight growth velocity after return to birth weight was 11.8±5.5 g/(kg·d). The duration of hospitalization was 42.2±20.8 days and the corrected gestational age was 36.6±2.7 weeks at the time of discharge. At birth, the percentage of birth weight below P10 was 52.6%, and below P3 was 29.0%. At the time of discharge, the percentage of weight below P10 was 80.9%, and below P3 was 63.6%. There were differences between two time points (P2周、出生体质量<1500 g的早产儿临床资料,包括住院期间的喂养方式、营养状况、并发症及诊断和治疗,并对早产儿住院期间的肠内外营养、体质量增长情况进行描述性分析,并分析EUGR的相关因素。结果入选572例早产儿,出生胎龄(30.6±2.0)周,出生体质量(1255.7±164.8)g;开始肠道喂养的时间为(68.2±85.4)h,口服能量达到100 kcal/(kg·d)(1cal=418.68J)的日龄为(29.9±14.1)d;住院期间在恢复至出生体质量后其体质量增长速度为(11.8±5.5)g

    Full Text Available Despite the fact that feeding a very low birth weight (VLBW neonate is a fundamental and inevitable part of its management, this is a field which is beset with controversies. Optimal nutrition improves growth and neurological outcomes, and reduces the incidence of sepsis and possibly even retinopathy of prematurity. There is a great deal of heterogeneity of practice among neonatologists and pediatricians regarding feeding VLBW infants. A working group on feeding guidelines for VLBW infants was constituted in McMaster University, Canada. The group listed a number of important questions that had to be answered with respect to feeding VLBW infants, systematically reviewed the literature, critically appraised the level of evidence, and generated a comprehensive set of guidelines. These guidelines form the basis of this state-of-art review. The review touches upon trophic feeding, nutritional feeding, fortification, feeding in special circumstances, assessment of feed tolerance, and management of gastric residuals, gastro-esophageal reflux, and glycerin enemas.

    To review the literature that addresses the relationship between prematurity, birth weight, and development of language in Brazilian children. A systematic review of studies published between 2003 and 2012 in English and Portuguese and indexed in PubMed, LILACS, and SciELO. The following key words were used in the searches: Prematuro, Prematuridade, Linguagem, Prematurity, Language, Speech-Language Pathology. Fifty-seven articles were retrieved, 13 of which were included in the systematic review. The results showed an association between prematurity, low birth weight, and language development. In studies that made comparisons between preterm and term infants, there was evidence that preterm infants had poorer performance on indicators of language. It was also observed that children born with lower birth weight had a poorer performance on measures of language when compared to children with higher weight and closer to 37 weeks of gestational age. Regarding the type of language assessed, expression proved to be more impaired than reception. Higher parental education and family income were indicated as protective factors for the development of language. Conversely, lower birth weight and higher degree of prematurity emerged as risk factors. Preterm birth and low birth weight poses risks for the language development of children, especially in the first years of life. Therefore, it is essential that pediatricians are aware of the language development of these children to ensure proper treatment. Copyright © 2015 Sociedade Brasileira de Pediatria.

    Objective To observe and analyze the effects of immune nutritional enhancing therapy on the prognosis of premature very low birth weight infants(VLBWI). Methods One hundred and six cases of premature VLBWI were se-lected as the research objects and randomly divided into the observation group and the control group. Fifty-three cases were included into each group. The newborn infants in the observation group were fed with breast milk combined with human milk fortifier,while newborn infants in the control group were fed with formative milk for the premature infants. The hospi-talized time and serum albumin levels,weight at discharge,hospital infection rates and the incidences of gastrointestinal dysfunction of the infants in the two groups were observed and compared. Results The differences of the hospitalized time and the weight at discharge of the infants in the two groups were not significant(P > 0. 05),while the serum albumin level of the observation group was significantly higher than that of the control group(P 0. 05). Conclusions Early application of breast feeding combined with human milk fortifier in the treatment of premature VLBWI can significantly improve the nutritional status of the infants,and contribute to the achievement of the‘catch-up growth’. Meanwhile,the effects of promoting the immune function of the premature infants of this therapy are equivalent to the application of the formula milk feeding.%目的:观察和分析免疫强化营养治疗对早产极低出生体质量儿(VLBWI)预后的影响。方法选取106例早产 VLBWI 作为研究对象,将其随机分为观察组和对照组,每组53例,观察组新生儿应用母乳加母乳强化剂的喂养方式,对照组新生儿应用早产儿配方奶进行喂养,对两组新生儿的住院时间和血清白蛋白水平、出院时体质量、住院期间感染发生率和胃肠功能紊乱发生率的情况进行观察和比较。结果两组在住院时间和出院体质

    To determine the dynamic morphologic development of the human fovea in vivo using portable spectral domain-optical coherence tomography (SD-OCT). Prospective, observational case series. Thirty-one prematurely born neonates, 9 children, and 9 adults. Sixty-two neonates were enrolled in this study. After examination for retinopathy of prematurity (ROP), SD-OCT imaging was performed at the bedside in nonsedated infants aged 31 to 41 weeks postmenstrual age (PMA) (= gestational age in weeks + chronologic age) and at outpatient follow-up ophthalmic examinations. Thirty-one neonates met eligibility criteria. Nine children and nine adults without ocular pathology served as control groups. Semiautomatic retinal layer segmentation was performed. Central foveal thickness, foveal to parafoveal (FP) ratio (central foveal thickness divided by thickness 1000 μm from the foveal center), and 3-dimensional thickness maps were analyzed. In vivo determination of foveal morphology, layer segmentation, analysis of subcellular changes, and spatiotemporal layer shifting. In contrast with the adult fovea, several signs of immaturity were observed in the neonates: a shallow foveal pit, persistence of inner retinal layers (IRLs), and a thin photoreceptor layer (PRL) that was thinnest at the foveal center. Three-dimensional mapping showed displacement of retinal layers out of the foveal center as the fovea matured and the progressive formation of the inner/outer segment band in the opposite direction. The FP-IRL ratios decreased as IRL migrated before term and minimally after that, whereas FP-PRL ratios increased as PRL subcellular elements formed closer to term and into childhood. A surprising finding was the presence of cystoid macular edema in 58% of premature neonates that appeared to affect inner foveal maturation. This study provides the first view into the development of living cellular layers of the human retina and of subcellular specialization at the fovea in premature infant eyes

    Kelly, Michelle M; Dean, Spencer

    Prematurity affects a significant portion (10-12%) of children in the Unites States, with potential for physical, psychological, neurodevelopmental, and behavioral impairments continuing long past the neonatal period. The specific aim of this research was to evaluate pediatric primary and specialty care providers' knowledge and understanding of neurodevelopmental outcomes of children born prematurely. Pediatric nurse practitioner (PNP) members of the National Association of Pediatric Nurse Practitioners participated in an online survey using the 33-item Premature Birth Knowledge Scale (PB-KS) to assess their knowledge of current neurodevelopmental outcomes of children born prematurely. Neither years of practice as a registered nurse nor as a PNP predicted performance on the PB-KS. The mean score on the PB-KS in the PNP sample was 17.8 (possible score = 0-33), with a mean accuracy of 53.9%. Higher scores on the PB-KS were correlated with higher perceived level of preparation to care for children born prematurely. To our knowledge, this is the first study to use the PB-KS with pediatric primary and specialty providers. PNPs are uniquely situated to educate and support families facing the long-term consequences of premature birth; to do so they must maintain accurate understanding of current outcomes.

    Cesarean delivery is being increasingly used by obstetricians for indicated deliveries in the second stage of labor. Unplanned extension of the uterine incision involving the cervix often occurs with these surgeries. Therefore, we hypothesized that cesarean delivery in the second stage of labor may increase the rate of subsequent spontaneous premature birth. We sought to determine if cesarean delivery in the late first stage of labor or in the second stage of labor increases the risk of a subsequent spontaneous preterm birth. We conducted a retrospective cohort study of matched first and second births from a large Canadian perinatal database. The primary outcomes were spontaneous premature birth cesarean delivery. The protocol and analysis plan was registered prior to obtaining data at Open Science Foundation. In total, 189,021 paired first and second births were identified. The risk of spontaneous preterm delivery cesarean delivery in the second stage of labor (relative risk, 1.57; 95% confidence interval, 1.43-1.73 and relative risk, 2.12; 95% confidence interval, 1.67-2.68, respectively). The risk of perinatal death in the second birth, excluding congenital anomalies, was also correspondingly increased (relative risk, 1.44; 95% confidence interval, 1.05-1.96). Cesarean delivery in second stage of labor was associated with a 2-fold increase in the risk of spontaneous preterm birth <32 weeks of gestation in a subsequent birth. This information may inform management of operative delivery in the second stage. Copyright © 2017 Elsevier Inc. All rights reserved.

    Evidence from different screening programs indicated that the rate of congenital hypothyroidism (CH) was higher in pre-term and low-birth-weight (LBW) newborns than normal ones. Incomplete development of hypothalamic-pituitary axis in this group of neonates results in the delayed rise of TSH and missing cases with CH. Hence, there is a great need for a practicable systematic screening method for proper diagnosis of CH in this group of neonates. In this review, we systematically reviewed papers with the following key words ([Congenital Hypothyroidism AND Screening AND Thyroxine AND Thyroid Stimulating Hormone AND Low Birth Weight AND Premature]) in international electronic databases including PubMed, Scopus, and Google Scholar. After quality assessment of selected documents, data of finally included papers were extracted. In this review, 1452 papers (PubMed: 617; Scopus: 714; Google scholar: 121) were identified through electronic database search. One hundred and ninety four articles were assessed for eligibility, from which 36 qualified articles were selected for final evaluation. From the reviewed articles, 38.9%, 11.11% and 8.3% recommended rescreening in this group of neonates, lowering the screening cutoff of TSH and using cutoffs according to the gestational age, respectively. Some of them (13.9%) recommended using both TSH and T4 for screening of preterm infants. After reviewing available data, we recommend repeating the screening test in pre-term, LBW and very-low- birth-weight (VLBW) infants at age of two, six and ten weeks by measuring TSH and FT4 levels simultaneously and considering TSH = 10 mU/L as the cutoff level for positive and suspicious cases.

    Full Text Available The objective of this time-series study carried out in São José dos Campos, a southeastern Brazilian city, between 01.01.2005 and 31.12.2009, was to estimate the role of maternal exposure to air pollutants and preterm births. Preterm newborns of mothers aged between 18 and 34 years, with at least eight years of schooling, singleton pregnancies and whose delivery was vaginal were included in the study. Logistic regression was used to estimate the role of particulate matter, ozone and sulfur dioxide on preterm delivery with lags of zero up to 30 days. Exposure to particulate matter was associated significantly with preterm newborns in lags of 0, 1 and 3 days; but no association was found between cumulative maternal exposure in lags of 7, 15 and 30 days and the outcome. Maternal exposure to particulate matter therefore has an acute effect on preterm births in a medium-sized Brazilian town.

    Background Birth characteristics, including weight and gestational age, may be associated with risk of Barrett’s esophagus (BE), the only known precursor for esophageal adenocarcinoma; however, data are limited. Aims To examine associations between various birth characteristics and BE, and whether these associations are mediated by known risk factors for BE. Methods Data were obtained from a cross-sectional study among eligible Veterans Affairs patients scheduled for an upper endoscopy, and a sample identified from primary care clinics. Participants underwent an esophagogastroduodenoscopy and completed a survey that captured information on sociodemographic and clinical factors, as well as birth information. We compared 263 patients with histologically confirmed BE to 1,416 controls without BE on endoscopy. Odds ratios (ORs) and 95 % confidence intervals (CIs) were calculated using multivariate logistic regression. Results Premature birth was independently associated with risk of BE after adjusted by age, sex, race, and other birth characteristics (OR 3.28, 95% CI 1.22–8.79). On the other hand, large for gestational age was inversely associated with risk of BE (OR 0.46, 95% CI 0.21–0.98). These effects were stronger for patients with long-segment BE than short-segment BE. The associations were not mediated by gastroesophageal reflux disease symptoms, use of proton pump inhibitors, Helicobacter Pylori infection, waist-hip-ratio, height or presence of hiatus hernia. Conclusions Premature birth and large for gestational age may be associated with risk of BE in adults. These associations do not appear to be mediated through known risk factors for BE; however, additional studies are required to confirm our findings. PMID:26611860

To find an overall prevalence of low birth weight babies amongst hospital births in Meerut city. 2. To identify and quantify the effects of some risk factors for low birth weight. Setting: District women Hospital of Meerut city of western U.P. Study Design: Hospital based matched case-control study. Sample size: 491 low birth weight babies as ‘cases’ and an equal number of babies of normal birth weight in ‘control’ group matched for maternal age, sex of baby, birth order and institution of delivery. Study variables: Socio-economic Status: maternal biological factors including obstetric history: antenatal factors: nutritional factors: history of abortion: toxaemia of pregnancy etc. Results: Overall proportion of low birth weight babies was found to be 21.8% amongst hospital live births and 30.9% born to mothers aged below 30 years of age. Low maternal weight, under nutrition, lack of antenatal care, short inter-pregnancy interval, toxacmia of pregnancy were independent factors increasing the risk of low birth weight significantly. Conclusions: The study suggested that a substantial proportion of low birth weight babies can be averted by improving maternal nutritional status including anemic condition, birth spacing and proper antenatal care.

    Dutton, Gordon N

    2013-08-01

    In children born prematurely, impairment of vision due to damage to the brain is more common than due to retinopathy of prematurity. Yet, the diagnosis of cerebral visual impairment may be missed. The subject of cerebral visual impairment in children is reviewed in order to explain and draw attention to the types of visual deficits and behaviours that may result as a sequel to premature birth. A wide range of sources of data has been employed to assemble this overview. The principal reference source is PubMed. The material presented highlights the origin and range of visual deficits that result from damage to the brain, related to premature birth. Deficits of primary visual functions, perceptual dysfunction, simultanagnostic visual disorders and impaired visual guidance of movement (optic ataxia), as well as disorders of visual attention and memory, can occur in a variety of combinations and degrees. The resulting behavioural outcomes are described. Identification and characterisation of impaired vision, due to prematurity associated damage to the brain, are essential. This is required so as to ensure that affected children are not inappropriately disadvantaged on account of the diagnosis being missed or inadequately acted upon, but instead, they are managed optimally, both at home and at school, so that their development is enhanced to the greatest advantage.

    Full Text Available In recent decades, steady progress in the field of physiopathology and the use of increasingly sophisticated technological procedures have resulted in an increase in the survival rates of babies born preterm. However, some of these individuals, although surviving, may at times be faced with severe consequences. Some conditions may be manifested at an early age (particularly dysmorphisms as well as neurological and ophthalmological conditions, whilst others (namely renal and cardiovascular events, evolve gradually and are manifested only years later. In a number of reports in literature it has been demonstrated how prematurity and consequent low weight at birth are risk factors for developing hypercholesterolemia, arterial hypertension, obesity, type 2 diabetes, QTc interval prolongation at basal electrocardiogram, early endothelial dysfunction, structural and functional cardiac modifications, and increased death rates from coronary heart disease. Even some drugs used in the neonatal management of preterm babies may have a detrimental effect on their future cardiac function. The aim of this narrative review was to overview the up to know few reports about metabolomics (a new and promising technique which allows the systematic study of the complete set of metabolites in a biological sample applied to the identification of a possible future cardiovascular system involvement in subjects born preterm. An outlook of the requirements for future researches has been also discussed.

    It is estimated that 8 to 26 percent of infants are born with low birth weight (LBW) worldwide. These children are at risk for medical problems in childhood and adulthood and often have poor oral health. The influence of fetal growth on birth weight and its relevance to childhood growth and future adult health is controversial. Evidence now indicates that the postnatal period is a critical time when nutrition may predispose the child to lifelong metabolic disturbance and obesity. Given the lack of consensus on optimum infant nutrition for LBW, premature, and small-for-gestational-age infants, many such infants may be suboptimally managed. This may result in rapid postnatal weight gain and ongoing health problems. The purpose of this review was to summarize medical terminology and issues related to fetal growth, morbidity associated with being born low birth weight, premature, or small for gestational age, and the importance of appropriate nutrition in such infants. Pediatric dentists can play an important role in supporting healthy feeding practices and improving long-term health in these children. Early integrated medical and dental care should be encouraged for all children with low birth weight.

    2012-04-01

    Bronchopulmonary dysplasia (BPD), also known as chronic lung disease of prematurity, is the major cause of pulmonary disease in infants. The pathophysiology and management of BPD have evolved over the past four decades as improved neonatal intensive care unit (NICU) modalities have increased survival rates. The likelihood for developing BPD increases with the degree of prematurity and reaches 25-35% in very low-birth-weight and extremely low-birth-weight infants. BPD affects many organ systems, and infants with BPD are at increased risk for rehospitalization and numerous complications following NICU discharge. The management of BPD and medically related problems, particularly during the first 2 years of life, remains a continuing challenge for parents and healthcare providers. It is important that a multidisciplinary team consisting of the neonatologist/attending physician, primary care physician, and other specialized support staff work in concert and meet regularly to provide continuity of care and accurate patient assessments.

    Full Text Available BACKGROUND: Umbilical cord milking (UCM improves blood pressure and urine output, and decreases the need for transfusions in comparison to immediate cord clamping (ICC. The immediate effect of UCM in the first few minutes of life and the impact on neonatal resuscitation has not been described. METHODS: Women admitted to a tertiary care center and delivering before 32 weeks gestation were randomized to receive UCM or ICC. A blinded analysis of physiologic data collected on the newborns in the delivery room was performed using a data acquisition system. Heart rate (HR, SpO2, mean airway pressure (MAP, and FiO2 in the delivery room were compared between infants receiving UCM and infants with ICC. RESULTS: 41 of 60 neonates who were enrolled and randomized had data from analog tracings at birth. 20 of these infants received UCM and 21 had ICC. Infants receiving UCM had higher heart rates and higher SpO2 over the first 5 minutes of life, were exposed to less FiO2 over the first 10 minutes of life than infants with ICC. CONCLUSIONS: UCM when compared to ICC had decreased need for support immediately following delivery, and in situations where resuscitation interventions were needed immediately, UCM has the advantage of being completed in a very short time to improve stability following delivery.

    Full Text Available Gastro-esophageal reflux (GER is one of the common problems of neonatal intensive care units. Although this condition does not always need to be treated, it occasionally causes clinically serious consequences. Initial management is medical; however, in some cases surgery might be required. A premature neonate with birth weight of 1370 grams was managed in our ICU. The patient was mechanical ventilator dependent due to GER. The patient needed Nissen fundoplication for successfully weaning off the ventilator.

    Full Text Available Introduction & Objective: Recent studies have presented evidence that periodontal disease in pregnant women may be a determining factor for newborn’s low birth weight. The present investigation was carried out to verify whether there is an association between maternal periodontal disease and low birth weight of newborns.Materials and Methods: This was a case-control study on 330 women, containing 110 mothers having live newborns with weight 2500 g (control group. The existence of an association between periodontal disease and newborn’s low birth weight was evaluated by means of analytic statistics that considered other risk factors for low weight. The two groups were compared with regard to urinary infection, preeclampsia, premature rupture of membrane, placenta previa, primiparous, smoking, age, height, socioeconomic status and periodontal disease.Results: There were no statistically significant differences between the case and control groups for any of the covariables (P>0.05, but there was significant differences for principal independent variable (periodontal disease P<0.05.Conclusion: Results indicated a positive association between periodontal disease and newborn’s low birth weight. Thus periodontal disease is a possible risk factor for low birth weight.

    Full Text Available Background and purpose: Low birth weight (LBW; birthweight 2500 g. or below is a public health problem, because it is associated with increased risk of morbidity and mortality. This prospective study was conducted during March 2002 - 2003, to determine the incidence of low birth weight infants and associated risk factors in neonates born at Shahid Rajaee Hospital in Tonekabone, Iran.Materials and methods: For every LBW case, maternal age, sex, gestational age, parity, route of delivery and spacing between pregnancies of low birth weight were analyzed. For control, the first baby born before and immediately after the LBW baby who weighed more than 2500 g. at birth were analyzed.Results: The results revealed that the incidence of low birth weight was 4.2 % which is lower than population of other cities and only 0.34% (7 cases of newborns weighted 1500 g. or less. The higher incidence of low birth weight was found in the primigravid (P=0.042, in cesarean section (P=0.025 and close spacing of pregnancy (P=0.033. Maternal age and sex of baby had no significant effect on the incidence of low birth weight. There were more premature deliveries in cases than controls (P=0.000.Conclusion: According to present findings, LBW incidence of albeit in Tonekabon in comparison with other cities throught the country is at acceptable level, prevention of premature delivery and conduction of health education programs for high risk groups, especially primigravid can lower the rates.

    To evaluate a possible association between neighbourhood socio-economic status and spontaneous premature birth in Alberta births. The study design was a retrospective cohort of all births in Alberta for the years 2001 and 2006. The primary outcome was spontaneous preterm birth at <37 weeks gestation. Neighbourhood socio-economic status was measured by the Pampalon Material Deprivation Index for each Statistics Canada census dissemination area. Births were linked to dissemination area using maternal postal codes. The analysis comprised 73,585 births, in which the rate of spontaneous preterm delivery at <37 weeks was 5.3%. The rates of spontaneous preterm delivery for each neighbourhood socio-economic category ranged from 4.9% (95% CI 4.5%-5.2%) in the highest category to 6.3% (95% CI 6.0%-6.7%) in the lowest (p<0.001). After controlling for smoking, parity, maternal age and year, we found that women living in the highest socio-economic status neighbourhoods had an adjusted spontaneous preterm birth rate of 5.1% (95% CI 4.7%-5.5%) compared to 6.0% (95% CI 5.6%-6.4%) for women living in the lowest (p=0.003). This study documented a modest increase in the risk of spontaneous preterm birth with low socio-economic status. The possibility of confounding bias cannot be ruled out.

    Birth weight is an important indicator of prenatal environment, and subtle variations of birth weight within the normal range have been associated with differential risk for cognitive and behavioral problems. Therefore, we aimed to determine if there are differences in birth weight between full-term children with uncomplicated new/recent-onset epilepsies and typically developing healthy controls. We further examined the relationships between birth weight and childhood/adolescent cognition, behavior, and academic achievement. One hundred eight children with new-onset/recent-onset epilepsy and 70 healthy controls underwent neuropsychological assessment. All participants were born full-term (>37 weeks) without birth complications. Parents were interviewed regarding their child's gestation, birth, and neurodevelopmental history. Birth weight of children with epilepsy was significantly lower than healthy controls (p = 0.023). Whereas birth weight (covaried with age, sex, handedness, and mother's education) was significantly associated with cognition in controls in multiple domains (intelligence, language, aspects of academic achievement), this relationship was absent in children with epilepsy. Birth weight was not associated with clinical epilepsy variables (age of onset, epilepsy syndrome) and was not predictive of a variety of other academic or psychiatric comorbidities of epilepsy. Although the origin of lower birth weight in children with epilepsy is unknown, these findings raise the possibility that abnormal prenatal environment may affect childhood-onset epilepsy. Furthermore, the positive relationship between birth weight and cognition evident in healthy controls was disrupted in children with epilepsy. However, birth weight was not related to academic and psychiatric comorbidities of childhood epilepsy.

    Objective: A large Danish birth cohort was used to test the independent and joint effects of perinatal measures associated with premature birth as predictors of the development of alcoholism in male and female subjects. Method: Subjects were born at the Copenhagen University Hospital between 1959 and 1961 (N = 9,125). A comprehensive series of measures was obtained for each of the 8,109 surviving and eligible infants before birth, during birth, shortly after birth, and at 1 year. The adult alcoholism outcome was defined as any ICD-10 F10 diagnosis (Mental and behavioral disorders due to alcohol use) or an equivalent ICD-8 diagnosis found in the Danish Psychiatric Central Research Register or the Municipal Alcohol Clinics of Copenhagen by 2007. Results: Multiple perinatal markers of premature birth independently predicted the development of an alcoholism diagnosis in male (n = 310) but not female (n = 138) subjects. Logistic regression modeling with a global prematurity score, adjusted for social status, maternal smoking, and gender, indicated a significant association of prematurity score for males (p premature birth are associated with gender-specific effects on the development of alcoholism in the male baby: small, premature, or growth-delayed male babies appear to be selectively vulnerable to alcoholic drinking years later.

    To investigate the influence of prenatal hospitalization before a premature birth, on the parental stressful experience, parental symptoms of post-traumatic stress and quality of parent-infant interaction during the hospitalization in neonatology. 51 preterm infants born and 25 full term infants control. Four groups: controls, premature without prenatal hospitalization, premature with a short (premature with a long (≥ 8 days) prenatal hospitalization. the Parental Stressor Scale: Neonatal Intensive Care Unit (PSS: NICU, Miles et al., 1993 [14]) and the Perinatal PTSD Questionnaire (PPQ, Quinnell and Hynan, 1999 [16]). When prenatal hospitalization of the mother occurred, parents acknowledged increased stress induced by the environmental factors during the infant's hospitalization. Furthermore, mothers from the group with a short prenatal hospitalization presented significantly more symptoms of post-traumatic stress. Parents presenting more symptoms of post-traumatic stress describe a significantly more difficult interaction with their infant in neonatology. This study highlights the necessity to deliver special care to women hospitalized shortly (premature baby. This group is at high risk of presenting post-traumatic stress symptoms, which could have a negative impact on the quality of parent-infant interactions. Copyright © 2012.

    OBJECTIVE: To identify the maternal body composition parameters that independently influence birth weight. STUDY DESIGN: A longitudinal prospective observational study in a large university teaching hospital. One hundred and eighty-four non-diabetic caucasian women with a singleton pregnancy were studied. In early pregnancy maternal weight and height were measured digitally in a standardised way and the body mass index (BMI) was calculated. At 28 and 37 weeks\\' gestation maternal body composition was assessed using segmental multifrequency bioelectrical impedance analysis. At delivery the baby was weighed and the clinical details were recorded. RESULTS: Of the women studied, 29.2% were overweight and 34.8% were obese. Birth weight did not correlate with maternal weight or BMI in early pregnancy. Birth weight correlated with gestational weight gain (GWG) before the third trimester (r=0.163, p=0.027), but not with GWG in the third trimester. Birth weight correlated with maternal fat-free mass, and not fat mass at 28 and 37 weeks gestation. Birth weight did not correlate with increases in maternal fat and fat-free masses between 28 and 37 weeks. CONCLUSIONS: Contrary to previous reports, we found that early pregnancy maternal BMI in a non-diabetic population does not influence birth weight. Interestingly, it was the GWG before the third trimester and not the GWG in the third trimester that influenced birth weight. Our findings have implications for the design of future intervention studies aimed at optimising gestational weight gain and birth weight. CONDENSATION: Maternal fat-free mass and gestational weight gain both influence birth weight.

    Previous studies have shown that woman's risk of breast cancer in later life is associated with her infants birth weights. The objective of this study was to determine if this association is independent of breast cancer risk factors, mother's own birth weight and to evaluate association between infants birth weight and hormonal environment during pregnancy. Independent association would have implications for understanding the mechanism, but also for prediction and prevention of breast cancer. Risk of breast cancer in relation to a first infant's birth weight, mother's own birth weight and breast cancer risk factors were evaluated in a prospective cohort of 410 women in the Framingham Study. Serum concentrations of estriol (E3), anti-estrogen alpha-fetoprotein (AFP), and pregnancy-associated plasma protein-A (PAPP-A) were measured in 23,824 pregnant women from a separate prospective cohort, the FASTER trial. During follow-up (median, 14 years) 31 women (7.6%) were diagnosed with breast cancer. Women with large birth weight infants (in the top quintile) had a higher breast cancer risk compared to other women (hazard ratio (HR), 2.5; 95% confidence interval (CI), 1.2-5.2; P = 0.012). The finding was not affected by adjustment for birth weight of the mother and traditional breast cancer risk factors (adjusted HR, 2.5; 95% CI, 1.2-5.6; P = 0.021). An infant's birth weight had a strong positive relationship with the mother's serum E3/AFP ratio and PAPP-A concentration during pregnancy. Adjustment for breast cancer risk factors did not have a material effect on these relationships. Giving birth to an infant with high birth weight was associated with increased breast cancer risk in later life, independently of mother's own birth weight and breast cancer risk factors and was also associated with a hormonal environment during pregnancy favoring future breast cancer development and progression.

    Full Text Available Premature is a newborn alive whose birth weight is equal to or less than 2500 grams, regardless of the duration of gestation. Prematurity have sometimes negative effects on child development by slowing the psychomotor development (child goes to talk later, you can recover delay until the age of 3-5 years. Some of these older children, will be clumsy. PURPOSE: To verify the importance of the adapted recovery program making a correlation between neuro-psychological assessment tests and weight of children born prematurely. HYPOTHESIS: Early systematic and continuous intervention, using adapted physical therapy methods lead to a improved neuromotor development of the premature by reaching the normal range. MATERIAL AND METHODS The study included 10 children, 6 boys and 4 girls, born prematurely. They were subjected to the test "assessment of neuro-psychological development in children 0-36 months" (it is a battery of tests that help to evaluate their development monthly and test weight. Applied therapeutic program included: exercise (performed by the game, massage, neuromotor rehabilitation methods (Bobath, Vojta, Kabat, hydrotherapy and music therapy. RESULTS AND DISCUSSION: If neuro-psychological tests, we proceeded to calculate averages scores for the 3 test, which is further correlated with children's weight. Average scores range between 7 and 10. 333, with an overall average of 9.371. In all 3 tests averages ranging from 8,575 in the initial stage, in 9386, and 10,152 in the midway point in the final stage. CONCLUSIONS: Weight, explain in smaller proportions, and other parameters and results of neuro-psychological tests children (65.6%. ANOVA models indicate statistically significant relationships between parameters and neuro-psychological testing stages, showing progressive improvement of children's performance. Following statistical interpretation can confirm the effectiveness of the recovery program implemented so we suggest to the parents

  15. Executive functions of six-year-old boys with normal birth weight and gestational age.

    Directory of Open Access Journals (Sweden)

    Desiree Yee-Ling Phua

    Full Text Available Impaired fetal development, reflected by low birth weight or prematurity, predicts an increased risk for psychopathology, especially attention deficit hyperactivity disorder (ADHD. Such effects cut across the normal range of birth weight and gestation. Despite the strength of existing epidemiological data, cognitive pathways that link fetal development to mental health are largely unknown. In this study we examined the relation of birth weight (>2500 g and gestational age (37-41 weeks within the normal range with specific executive functions in 195 Singaporean six-year-old boys of Chinese ethnicity. Birth weight adjusted for gestational age was used as indicator of fetal growth while gestational age was indicative of fetal maturity. Linear regression revealed that increased fetal growth within the normal range is associated with an improved ability to learn rules during the intra/extra-dimensional shift task and to retain visual information for short period of time during the delayed matching to sample task. Moreover, faster and consistent reaction times during the stop-signal task were observed among boys born at term, but with higher gestational age. Hence, even among boys born at term with normal birth weight, variations in fetal growth and maturity showed distinct effects on specific executive functions.

    Full Text Available Intraclass correlation coefficients were calculated for the birth weights of twins born at three southeastern Brazilian hospitals, after adjustment of the natural logarithms of these weights for gestational age, its quadratic and cubic terms, sex, and their interactions. The data indicate that fetal genetic effect on birth weight might have the opportunity to be demonstrated by children born to undernourished women. Undernourishment, acting as a selective force, might enhance the existence of genotypes that determine less need of food for normal development.Os coeficientes de correlação intraclasse foram calculados para o peso de gêmeos nascidos em três maternidades do sudeste brasileiro, depois de ajustar os logaritmos naturais desses pesos para a idade gestacional, seus termos quadrático e cúbico, sexo e interações dessas variáveis. Os dados obtidos indicaram que o efeito genético fetal sobre o peso ao nascer teria a oportunidade de ser demonstrado por recém-nascidos de mães subnutridas. A subnutrição, atuando como força seletiva, realçaria a existência de genótipos que determinam menor necessidade nutricional para o desenvolvimento normal.

    Scientific evidence is insufficient to answer the question of whether premature birth causes altered tooth-crown dimensions. To evaluate permanent tooth-crown dimensions in prematurely born children and to compare the findings with full-term born controls. Preterm children of 8-10 years of age were selected from the Swedish Medical Birth Register. One group consisted of 36 extremely preterm children (born before the 29th gestational week); the other group included 37 very preterm children (born during gestational weeks 29-32). The preterm children were compared with 41 matched full-term born children. Clinical examination and study casts were performed on all children. Permanent maxillary and mandibular first molars, central incisors, and laterals were measured with a digital sliding caliper on study casts. The tooth-crowns were measured both mesio-distal and bucco-lingual. Both the mesio-distal and bucco-lingual measurements in the maxillary and mandibular first molars had a significantly smaller width in the extremely preterm group compared with the full-term group. The central incisors and lower laterals were significantly smaller mesio-distally in the extremely preterm group compared to the full-term group. A reduction in tooth size of 4-9% was found between the extremely preterm group and the full-term group for both boys and girls. The maxillary first molars and mandibular left first molar were also smaller mesio-distally in the extremely preterm group compared to the very preterm group. The results indicate that the more preterm the birth, the smaller the tooth-crown dimensions. Independent of gestational age girls had generally smaller teeth than boys. Premature birth is associated with reduced tooth-crown dimensions of permanent incisors and first molars.

    2010-11-01

    Research suggests a relationship between birth weight and season of birth, but findings vary across countries and underlying factors are not well understood. We examine the seasonality of birth weight and explore alternative hypotheses for its etiology-exposure to environmental factors and varying socioeconomic composition of mothers-in Chile. Birth weight of approximately 5 million Chilean singleton live births 37 of 41 weeks of gestation between 1987 and 2007 were analyzed for seasonality by using regression models with month dummies and parametric sinusoidal specifications. Multivariate models with socioeconomic covariates and interactions across geographic regions examine potential factors accounting for seasonal variation. Marked 12-month and 6-month periodic cycles were found. The amplitude and phase of the seasonal variation change across geographic regions. In the low-latitude northern region, there is a spring peak and a fall nadir, while in middle-latitude colder regions, a bimodal periodicity emerges with peaks in spring and fall, a pronounced winter nadir, and smaller nadir in the summer. Socioeconomic composition of mothers is found to vary with annual periodicity, but it does not account for the seasonality in birth weight. Environmental factors rather than the socioeconomic composition of mothers likely account for seasonal variation in birth weight. The change in periodicity of birth weight across latitudes is consistent with a beneficial exposure to sunlight both early and late in the pregnancy, and a detrimental late exposure to cold temperatures only in areas with low winter temperatures.

    2017-05-01

    The current study examines the relationship between premature birth and the age at which caregivers first become concerned with their child's development in a sample of 84 toddlers with autism spectrum disorder (ASD). The participants were split into two groups: those born prematurely and those born full term. The results indicate that the age of caregiver first concern is significantly younger for those born prematurely than those born full term. The average age caregivers reported first becoming concerned about their child's development was around 7 months for participants born prematurely and around 13 months for participants born full term. Possible explanations for the results and their implications are discussed.

  6. Which factors could explain the low birth weight paradox?

    2006-08-01

    Full Text Available OBJECTIVE: Low birth weight children are unusual among well-off families. However, in Brazil, low birth weight rate was higher in a more developed city than in a less developed one. The study objective was to find out the reasons to explain this paradox. METHODS: A study was carried out in two municipalities, Ribeirão Preto (Southeastern Brazil and São Luís (Northeastern Brazil, which low birth weight rates were 10.7% and 7.6% respectively. Data from two birth cohorts were analyzed: 2,839 newborns in Ribeirão Preto in 1994 and 2,439 births in São Luís in 1997-1998. Multiple logistic regression analysis was performed, adjusted for confounders. RESULTS: Low birth weight risk factors in São Luís were primiparity, maternal smoking and maternal age less than 18 years. In Ribeirão Preto, the associated variables were family income between one and three minimum wages, maternal age less than 18 and equal to or more than 35 years, maternal smoking and cesarean section. In a combined model including both cohorts, Ribeirão Preto presented a 45% higher risk of low birth weight than São Luís. When adjusted for maternal smoking habit, the excess risk for low birth weight in Ribeirão Preto compared to São Luís was reduced by 49%, but the confidence interval was marginally significant. Differences in cesarean section rates between both cities contributed to partially explain the paradox. CONCLUSIONS: Maternal smoking was the most important risk factor for explaining the difference in low birth weight between both cities. The other factors contributed little to explain the difference in low birth weight rates.

    The objective of this study was to understand the meanings that postpartum women assign to gestational hypertension that resulted in premature birth. Participants were 70 women, with a mean age of 28 years, 85.7% of whom delivered between the 32nd and 36th gestational week. A questionnaire with subjective questions was applied to identify the meanings of gestational hypertension and premature delivery for postpartum women. Results were analyzed based on the Theory of Social Representations. We observed the construction of a negative social representation, with death as the central nucleus and negative aspects as the peripheral nuclei. The latter derive from the risks the mother and fetus were exposed to during pregnancy and later in the postpartum period with the hospitalization of the child in the neonatal intensive care unit.

    Full Text Available OBJECTIVE: To examine the association between a woman's birth weight and her subsequent fecundability. METHOD: In this prospective cohort study, we included 2,773 Danish pregnancy planners enrolled in the internet-based cohort study "Snart-Gravid", conducted during 2007-2012. Participants were 18-40 years old at study entry, attempting to conceive, and were not receiving fertility treatment. Data on weight at birth were obtained from the Danish Medical Birth Registry and categorized as <2,500 grams, 2,500-2,999 grams, 3,000-3,999 grams, and ≥ 4,000 grams. In additional analyses, birth weight was categorized according to z-scores for each gestational week at birth. Time-to-pregnancy measured in cycles was used to compute fecundability ratios (FR and 95% confidence intervals (CI, using a proportional probabilities regression model. RESULTS: Relative to women with a birth weight of 3,000-3,999 grams, FRs adjusted for gestational age, year of birth, and maternal socio-demographic and medical factors were 0.99 (95% CI: 0.73;1.34, 0.99 (95% CI: 0.87;1.12, and 1.08 (95% CI: 0.94;1.24 for birth weight <2,500 grams, 2,500-2,999 grams, and ≥ 4,000 grams, respectively. Estimates remained unchanged after further adjustment for markers of the participant's mother's fecundability. We obtained similar results when we restricted to women who were born at term, and to women who had attempted to conceive for a maximum of 6 cycles before study entry. Results remained similar when we estimated FRs according to z-scores of birth weight. CONCLUSION: Our results indicate that birth weight appears not to be an important determinant of fecundability.

    The aim of this work is to provide an overview of the recommendations in the current literature for the induction of lung maturation therapy. In particular, special attention is focused on specific situations, such as chorioamnionitis, intrauterine growth retardation and preeclampsia, which often lead to premature birth. Additionally, some aspects of antenatal steroid therapy, despite its widespread use, still require clarification. Among them is the repetitive administration of steroid therapy. On the basis of the Cochrane analysis of 2015, advantages and disadvantages for children and pregnant women are explained. Furthermore, the data on the use of antenatal steroid therapy in multiple pregnancies remain insufficient. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Research Questions: What are the bio â€" social determinants of birth weight of babies born in an urban- rural area? Objectives: 1. To study the biosocial determinants of birth weight 2. To determine which of the these affects birth weight. Design : Cross- sectional study. Setting : General hospital in Nagpur Participants: Mothers and their babies who were delivered in hospital. Study Variables : Mother’s age, parity, inter- pregnancy interval, socio-economic status, literacy status, antenatal care. Outcome Variable: Birth weight of the Infant. Statistical Analysis: Chi square test. Results: The proportion of low birth weight babies was high in teenage mothers(41.9% and those over the age of 30 years. Primi and grand multiparity were associated with higher prevalence of low birth weight babies (43.2% & 43.9% respectively. Interpregnancy interval of less than one and a half years had a high prevalence of LBW babies (44.7% but an interval of 5 years was also a risk as there were other associated risk factors like secondary sterility, tuberculosis etc. Low socio-economic status and low literacy levels were associated with significant proportion of LBW babies. Those mothers who had received adequate antenatal care gave birth to a significantly lower proportion of LBW babies than those who has not received antenatal care. Conclusion: Birthweight is determined by biosocial factors which are recognisable and some of which can be controlled.

    We examined the associations between birth weight and intelligence at 3 different adult ages. The Copenhagen Perinatal Cohort is comprised of children born in Copenhagen from 1959 to 1961. Information on birth weight and ≥1 tests of intelligence was available for 4696 members of the cohort. Intelligence was assessed at a mean age of 19 years with the Børge Priens Prøve test, at age 28 years with the Wechsler Adult Intelligence Scale, and at age 50 years with the Intelligenz-Struktur-Test 2000 R. Birth weight was significantly associated with intelligence at all 3 follow-up assessments, with intelligence scores increasing across 4 birth weight categories and declining for the highest birth weight category. The adjusted differences between those in the 5 IQ points at all 3 follow-up assessments, corresponding to one-third of a SD. The association was stable from young adulthood into midlife,and not weaker at age 50 years. Adjustment for potential confounding factors, including infant socioeconomic status and gestational age, did not dilute the associations, and associations with intelligence were evident across the normal birth weight range and so were not accounted for by low birth weight only. The association between birth weight and intelligence is stable from young adulthood into midlife. These long-term cognitive consequences may imply that even small shifts in the distribution of birth size, in normal-sized infants as well, may have a large impact at the population level.

    The study was carried out in order to verify the effects of piglets’ weight at birth on their surface temperature change (ST) after birth, and its relationship with ingestion time of colostrum. Piglets from four different sows were weighed at birth and divided into a totally randomized design with three treatments according to birth weight (PBW): T1 - less than 1.00 kg, T2 - 1.00 to 1.39 kg, and T3 - higher than or equal to 1.40 kg. The time spent for the first colostrum ingestion was recorded (TFS). Images of piglets’ surface by thermal imaging camera were recorded at birth (STB) and 15, 30, 45, 60, and 120 min after birth. The air temperature and relative humidity were recorded every 30 min and the indexes of temperature and humidity (THI) were calculated. A ST drop after 15 min from birth was observed, increasing again after sixty minutes. Positive correlations were found between the PBW and the ST at 30 and 45 min after birth. The PBW was negatively correlated with the TFS. The THI showed high negative correlations (−0.824 and −0.815) with STB and after 15 min from birth. The piglet’s surface temperature at birth was positively correlated with temperature thereof to 15 min, influencing therefore the temperatures in the interval of 45 to 120 min. The birth weight contributes significantly to postnatal hypothermia and consequently to the time it takes for piglets ingest colostrum, requiring special attention to those of low birth weight.

    This study examines the association between maternal factors and low birth weight among newborns at a tertiary hospital in Malaysia. This was a cross-sectional study where mothers were followed through from first booking till delivery. There were 666 mothers who delivered from May 2007 to March 2008. Infants' birth weight were compared with maternal age, pre-pregnancy BMI, fathers BMI, parity, ethnicity, per capita monthly income, and maternal blood pressure during pregnancy. A multiple logistic regressions was used to determine the relationship of maternal factors and low birth weight, while the ROC curve was constructed to assess the sensitivity and specificity of the predictive model. Among the significant risk factors of low birth weight were older age (35 years and above), low pre-pregnancy BMI (per capita monthly income were included in the analysis.

    Malnutrition in preterm low birth weight infants has adverse long-term metabolic, growth, and neurodevelopmental effects. In the past 3 decades, parenteral nutrition, enriched preterm formula, and fortification of human milk have been used to alleviate these adverse effects. Unfortified human breast milk does not provide sufficient nutrients for the growth and development of preterm infants at the volumes recommended; however, it is usually the only source of nutrition available for such infants in low-resource countries. Many newborns, including very low birth weight infants, are surviving in these countries because of concerted efforts to achieve the fourth millennium development goal. These efforts have not addressed the nutrition needs of sick preterm very low birth weight infants. The authors report 3 cases of severe acute malnutrition in very low birth weight newborns and suggest possible interventions.

    Both higher and lower fetal growth are associated with cardio-metabolic health later in life, suggesting that prenatal developmental programming determines long-term cardiovascular disease risk. Epigenetic mechanisms, which orchestrate fetal growth and development, may offer insight on the early programming of health and disease. We investigated whether birth weight-for-gestational is associated with DNA methylation at birth and mid-childhood, measured via the Infinium 450K array. Participants were from Project Viva, a pre-birth cohort of pregnant women and their children in Eastern Massachusetts. After exclusion of participants with maternal type 1 or 2 diabetes and gestational age birth weight-for-gestational age z-score was associated with cord blood DNA methylation at 34 CpGs (false discovery rate P birth weight, and several other CpGs map to genes relevant to fetal growth and development. Namely, higher birth weight-for-gestational age was associated with higher methylation at four CpGs at the PBX1 locus (e.g., β (95% CI) for lead signal at cg06750897 = 1.9 (1.2, 2.6)), which encodes a transcription factor that regulates embryonic development. Birth weight-for-gestational age was also associated with mid-childhood blood DNA methylation at four of the 34 CpGs identified in cord blood analyses, including sites at the PBX1 locus described. We identified CpG sites where birth weight-for-gestational age was associated with DNA methylation at birth, and for a subset of these sites, birth weight-for-gestational age was also associated with DNA methylation at mid-childhood.

    Pregnancy considerably increases iron needs in a mother and her fetus. The purpose of this study was to assess the relationship between maternal hemoglobin concentration in labor with neonatal birth weight. A population-based study in Shahid Sadughi Hospital in Yazd, Iran, was performed by comparing 1842 singleton term pregnancies of patients with and without anemia and their newborns. Maternal characteristics, including hemoglobin values, were recorded at the labor visit. Maternal anemia was defined as hemoglobin concentration lower than 10 g/dl during pregnancy. Main outcome measures included birth weight and Apgar score. Linear and logistic regression models were used to analyze data. Anemia (Hb 13 g/dl) increased the risk of low birth weight but it was not significant. The risk of a low Apgar score was significantly increased in women with anemia. The minimum incidence of low birth weight occurs in association with a hemoglobin concentration of 10-13 g/dl. Maternal anemia was significantly associated with effect on birth weight. Also Hb > 13 g/dl was also associated with an increased risk of low birth weight.

    Full Text Available BACKGROUND: Previous studies have shown that woman's risk of breast cancer in later life is associated with her infants birth weights. The objective of this study was to determine if this association is independent of breast cancer risk factors, mother's own birth weight and to evaluate association between infants birth weight and hormonal environment during pregnancy. Independent association would have implications for understanding the mechanism, but also for prediction and prevention of breast cancer. METHODS AND FINDINGS: Risk of breast cancer in relation to a first infant's birth weight, mother's own birth weight and breast cancer risk factors were evaluated in a prospective cohort of 410 women in the Framingham Study. Serum concentrations of estriol (E3, anti-estrogen alpha-fetoprotein (AFP, and pregnancy-associated plasma protein-A (PAPP-A were measured in 23,824 pregnant women from a separate prospective cohort, the FASTER trial. During follow-up (median, 14 years 31 women (7.6% were diagnosed with breast cancer. Women with large birth weight infants (in the top quintile had a higher breast cancer risk compared to other women (hazard ratio (HR, 2.5; 95% confidence interval (CI, 1.2-5.2; P = 0.012. The finding was not affected by adjustment for birth weight of the mother and traditional breast cancer risk factors (adjusted HR, 2.5; 95% CI, 1.2-5.6; P = 0.021. An infant's birth weight had a strong positive relationship with the mother's serum E3/AFP ratio and PAPP-A concentration during pregnancy. Adjustment for breast cancer risk factors did not have a material effect on these relationships. CONCLUSIONS: Giving birth to an infant with high birth weight was associated with increased breast cancer risk in later life, independently of mother's own birth weight and breast cancer risk factors and was also associated with a hormonal environment during pregnancy favoring future breast cancer development and progression.

    The Apgar score is a standardized tool for evaluating newborns in the delivery room. Despite its long history and widespread use, debate remains over its reliability of predicting neonatal outcomes, especially in extremely low-birth-weight premature infants. The aim of the study was to examine the relationship between the 5-minute Apgar score of extremely low-birth-weight infants, as it relates to survival and morbidities associated with prematurity and length of hospital stay. A retrospective query of the Alere neonatal database from 2001 to 2011 examined all infants less than 32 weeks' gestation and less than 1000-g birth weight. The 5-minute Apgar score was divided into 2 groups, score of 4 or greater or less than 4. The study compared results of the 5-minute Apgar score and associated morbidities in surviving infants. Statistical analyses included chi-square, Fisher exact test, t test, and multivariate regression. The sample consisted of 3898 infants with an 86.4% (n = 3366) survival rate. Controlling for gestational age and birth weight, surviving infants with a 5-minute Apgar score of less than 4 were more likely to demonstrate nonintact survival. Infants with a low 5-minute Apgar score have greater risk for mortality and morbidities associated with prematurity.

    Full Text Available Abstract Background Being born with low birth weight may have an impact on different aspects of mental health, psychosocial functioning and well-being; however results from studies in young adulthood have so far yielded mixed findings. The aim of this study was to assess the long-term impact in young adulthood on self-reported mental health, health-related quality of life, self-esteem and social relations by investigating differences between two low birth weight groups and a control group. Methods In a follow-up at 20 years of age, 43 preterm VLBW (birth weight ≤ 1500 g, 55 term SGA (birth weight  Results The VLBW and SGA groups reported significantly more mental health problems than controls. The VLBW group predominantly had internalizing problems, and the non-significant association with ASR Total score was reduced by the Intelligence Quotient (IQ. The SGA group had increased scores on both internalizing and externalizing problems, and the association with ASR Total score remained significant after adjusting for IQ in this group. Both low birth weight groups reported less interaction with friends and lower quality of life related to mental health domains than controls. Self-esteem scores were lower than in the control group for athletic competence (VLBW and social acceptance (SGA. Conclusion Our findings suggest that self-reported mental health and well-being in young adulthood may be adversely affected by low birth weight, irrespective of whether this is the result of premature birth or being born SGA at term.

    The incidence of low birth weight among white live-born infants from 1940 through 1978 was studied in various sections of the Love Canal. A statistically significant excess was found in the historic swale area from 1940 through 1953, the period when various chemicals were dumped in this disposal site. Potential confounding factors such as medical-therapeutic histories, smoking, education, maternal age, birth order, length of gestation, and urban-rural difference did not appear to account for this observation. Low birth weight rates were comparable to those of upstate New York from 1954 through 1978, the period when there was no deposition of chemical wastes.

    Full Text Available Introduction: Low birth weight (LBW is an important risk factor for childhood morbidity and mortality. Thus, it is an important public health concern. The study was aimed to identify the important socioeconomic, anthropometric and nutritional determinants associated with LBW. Factors included maternal household wealth status, age, literacy, nutritional status, parity, stature, gestational age and chewing betel nut or tobacco. Methods: The study included data of 4436 enrolled pregnant women in the Maternal and Infant Nutrition Intervention Matlab (MINIMat trial from November 2001 to October 2003. A random subset of (n= 3267 single live birth infants born between May 2002 and June 2004 with complete information on birth weight was analyzed. Pearson’s chi square test and logistic regression analysis were done to assess the association between the factors and LBW. Results: Almost one third of the infants were born with LBW and mean birth weight was 2693 g. Maternal poor wealth status, BMI less than 18.5, short stature (height < 152 cm and preterm (<37 weeks birth were found to be strong predictors of LBW. Women’s age, hemoglobin status and chewing tobacco or betel nut were not found to be associated with LBW. Conclusion: Women’s wealth status, literacy, maternal nutrition and prevention of preterm birth are the key factors that need to be considered to improve birth weight of infants.

    Full Text Available Low birth weight (LBW and preterm birth are one the most important causes of death in the world and therefore are considered as one of the major health problems. Global statistics demonstrates an increase in the prevalence of low birth weight in the developing countries. Low birth weight infants are exposed to complications such as major neurosensory impairements, cerebral palsy, cognitive and language delays, neuromotor developmental delay, blindness and hearing loss, behavioral and psychosocial disorders, learning difficulties and dysfunction in scholastic performances. The majority of infant's death and developmental disorders were due to disorders relating to prematurity and unspecified low birth weight. Infants weighing less than 2500 g, is a major determinant of both neonatal and infant mortality rates and, together with congenital anomalies (e.g., cardiac, central nervous system, and respiratory, contributes significantly to childhood morbidity. Various studies indicate that low birth weight infants are suffering from physiological and psychosocial disabilities, two to three times more than the other children. At school age, preterm and low birth weight infants have poorer physical growth, cognitive function, and school performance. These disadvantages appear to persist into adulthood and therefore have broad implications for society. Although the survival rates have increased dramatically and the incidence of morbidities has decreased, the complications are still considered to be associated with economical and social burdens. Most children with Low birth weight suffer from multiple disabilities. Therefore, they need special and consistent care. On demand of reducing the infant mortality rate, the need to decrease the complications in low birth weight and preterm infants should be considered by the policy makers in health care system. In this review article, we assessed current evidences on developmental outcomes of low birth weight and

    Objectives The prevalence of extreme prematurity at birth has increased, but little research has examined its impact on developmental outcomes in large representative samples within the United States. This study examined the association of extreme prematurity with kindergarteners' reading skills, mathematics skills and fine motor skills. Methods The early childhood longitudinal study-birth cohort, a representative sample of the US children born in 2001 was analyzed for this study. Early reading and mathematics skills and fine motor skills were compared among 200 extremely premature children (EPC) (gestational age sampling weights, children's age, race, sex, and general health status, and parental marital status and education among singleton children. Results At age 5 years, EPC were 2.6(95 % CI 1.7-3.8) times more likely to fail build a gate and were 3.1(95 % CI 1.6-5.8) times more likely to fail all four drawing tasks compared to TC (p values gate, 1.3[95 % CI 1.0-1.7]; failed to draw all four shapes, 1.1[95 % CI 0.8-1.6]) was not significantly different from TC. Mean early reading scale score (36.8[SE:1.3]) of EPC was 4.0 points lower than TC (p value sample of infants, the biological risk of extreme prematurity persists after adjusting for other factors related to development.

    Although human milk is generally accepted as the gold standard for the feeding of term infants, its use in the preterm and very low birth weight (VLBW) infants particularly in the initial period of birth has been more controversial. Little is known about the risks and benefits of early introduction of breast feeding on preterm VLBW infants. The primary object of this study was to evaluate the safety and benefit of early breast milk feeding in preterm VLBW newborns during their initial hospitalization periods. Therefore a prospective observational study was conducted among 37 preterm VLBW infants who were admitted to the Neonatal ward of Sir Salimullah Medical College and Mitford Hospital during the period of February 15th to July 25th, 2003. Oral feeding with breast milk was started within one hour of birth, and weight gain, feeding tolerance, nosocomial infection rate as well as other associated problems of pre-maturity, and postnatal growth curve were recorded upto 16th postnatal day. Seventy three percent of the newborns tolerate breast milk well from the very beginning, and the rest did not tolerate initially but all of them tolerate within 24 hours of birth. Infants had less initial weight loss (20 ± 10 gm) and faster recovery of birth weight. They regained their birth weight at 12th postnatal day. Hyper-bilirubinaemia was found in only 22% cases, and was observed in the group who initially didn't tolerate breast milk and was on intravenous fluid. Nobody developed symptomatic hypoglycemia or necrotizing enterocolitis (NEC). Two cases of sepsis and another two cases of minor infection like conjunctivitis and oral thrush have occurred. In conclusion it can be said that early breast milk feeding is safe in preterm VLBW infants and it helps to promote growth and reduce the need for intravenous line.

    Low birthweight (LBW) is the main known determinant of infant mortality. In spite of the sharp decrease in infant mortality rates and of the rise in survival rates for children with LBW, no important decrease in LBW rates has been observed in Neuquen, Argentina. The purpose of this study was to try to understand the risk factors for LBW, the frequency of LBW in the population, and the role of prenatal care in its prevention, as well as to develop a risk factor scale that could be used to identify women at higher risk of giving birth to a child with LBW. With this in mind we performed a cross-sectional study based on 50% of the data entered into the Perinatal Information System for 1988-1995 by the 29 hospitals in Neuquen province (46,171 births). The distribution of birthweight and the frequency of potential risk factors for LBW were examined. The relationship between such factors and LBW was studied using a logistic regression model. On the basis of the results obtained, an additive scale was drawn up and validated with the remaining 50% of the data for registered births. The highest odds ratio (OR) was seen in women who had no prenatal care (OR = 8.78; 95%CI: 6.7 to 11.4). ORs for inadequate prenatal care, lateness in attending the first prenatal visit, preeclampsia or eclampsia, hemorrhage and anomalies of the placenta or placental membranes, and a history of a previous child with LBW were greater than 2.0. The risk of having children with LBW was also higher in women over the age of 40, women under 20, single women, smoking mothers, women with an intergenesic interval of less than 18 months, and women with a body mass index of less than 20. Finally, there was a direct linear relationship between points on the risk scale and the risk of having a LBW infant.

    Fractional cerebral tissue oxygen extraction (FTOE) can be continuously monitored by simultaneous near-infrared spectroscopy (NIRS) and pulse oximetry. The objective of this study is to test the hypothesis that in very low birth weight (VLBW) infants, the more mature EEG activity is, the less variable FTOE is. A prospective study was conducted on VLBW infants (transcutaneous carbon dioxide tension. Increased maturation of EEG activity is associated with decreased variability in cerebral oxygen extraction. The implications of increased variability in FTOE on brain injury in premature infants need further exploration.

    The purpose of this study was to analyze the association between maternal Maya ancestry and the birth weight of infants born in Yucatan, Mexico, during 2013. A total of 30,435 singletons born at term (≥37 weeks) in Yucatan during 2013 were analyzed. Birth weights, gestational ages, and maternal socioeconomic data were provided by the Ministry of Health of Yucatan. Maternal Maya ancestry was defined by the presence of Maya surnames in: (1) non-Maya surnames (NM-NM), (2) one Maya surname (NM-M), and (3) two Maya surnames (M-M). Biological and socioeconomic parameters were compared between the categories of ancestry through one-way analysis of variance (ANOVA) and a multiple regression model was used to analyze the association between ancestry and infants' birth weight controlling for influence of covariates. Mean birth weight was 3,114 g (SD = 406) (NM-NM: 3,150 g [SD = 404], NM-M: 3,106 g [SD = 402], M-M: 3,088 g [SD = 408]). With the biological and socioeconomic variables statistically adjusted for, the presence of one and two maternal Maya surnames was associated with decreases in birth weight of 42 g and 63 g, respectively. None of the interactions between ancestry and other predictors was statistically significant. The lower mean birth weights of Maya infants are consistent with studies reporting poor growth and nutritional status of Maya children from Yucatan. Historically adverse socioeconomic conditions experienced by the Maya population are probably linked to the relatively lower birth weights of their infants. Am. J. Hum.

    Full Text Available Background and Objectives: Folic acid is a B vitamin which 5mg daily intake before gestation and until the tenth week of pregnancy is recommended. Since no study has been conducted in some regions of East Azerbaijan including Bostanabad, Khosroshahr and Sarab and no prevalence was spotted in country specific studies, therefore, the aim of this study was to determine the relationship between folic acid intake and infant birth weight. Material and Methods: This study was a retrospective cohort. In this study, 1939 of pregnant women who were referred to health care centers before pregnancy were selected randomly. They were divided into two groups: first group of pregnant women who regularly took folic acid before pregnancy and second group included the women who did not take folic acid supplements. Data were analyzed by SPSS 16 using T-Test and ANOVA. Results: This study was conducted on 1939 mothers who had an average age of 25.98 years and average infants birth weight was 3.209 kg. Totally, 92.9% of the mothers had regular consumption of folic acid during pregnancy. Analysis of the results showed that with increasing maternal BMI, birth weight also increased. It showed a significant relationship between regular folic acid intake and increase in infant birth weight. Conclusion : Our results showed that both high maternal pre-pregnancy weight and folic acid intake lead to higher birth weight infants.

    Full Text Available In the present study, we aimed to extend the characterization of the proposed naturalistic experimental model of piglets born with hypoxia by assessing the relationship between birth weight, intra partum asphyxia and gross indicators of neurophysiological alterations in newborn piglets. Three groups of 50 piglets each were classified according to their birth weight into normal (1000-1350 g, low (below 1000 g, and high (over 1350 g. In comparison to piglets within normal weight, those born with high birth weights showed acid-base imbalance as reflected by lower pH levels (7.03±0.01, hypercapnia (88.50±13.20 mmHg, and lactic acidosis (lactate levels: 89.40±26.30. These piglets had lower viability scores (5.40±0.60 and longer periods of time to contact the udder (52.30±8.30 than piglets with normal birth weight. In conclusion, data show that piglets with birth weight over 1350 g are at a higher risk of gross neurophysiological deficits, probably secondary to neonatal hypoxia.

    Although pregnant adolescents are at high risk of poor birth outcomes, the majority of adolescents go on to have full-term, healthy babies. Data from the National Longitudinal Study of Adolescent Health, a longitudinal study of a nationally representative sample of adolescents in grades 7-12 in the United States who were surveyed from 1994-1995 through 2008, were used to examine the epidemiology of preterm birth and low birth weight within this population. Outcomes of pregnancies were reported by participants in the fourth wave of data collection (when participants were 24-32 years of age); data were compared between female participants who reported a first singleton livebirth at less than 20 years of age (n = 1,101) and those who were 20 years of age or older (n = 2,846). Multivariable modeling was used to model outcomes; predictors included demographic characteristics and maternal health and behavior. Among black adolescents, low parental educational levels and older age at pregnancy were associated with higher birth weight, whereas low parental educational levels and being on birth control when one got pregnant were associated with higher gestational age. In nonblack adolescents, lower body mass index was associated with lower birth weight, whereas being unmarried was associated with lower gestational age. Predictors of birth outcomes may differ by age group and social context.

    Full Text Available Objective: Maternal factors such as age, health, diet, and environment are significantly associated with low birth weight. The objectives of this study were to determine the incidence, distribution and major risk factors of low birth weight in Hospital Kuala Lumpur.Materials and methods: A hospital based case–control study was done in Obstetric Ward of Maternity Hospital in Hospital Kuala Lumpur. Data was obtained using questionnaire and Performa. Out of 1021 deliveries, 330 were selected randomly as respondents that comprises of 110 cases and 220 controls. The outcome measure was low birth weight (<2500 grams.Results: The incidence of low birth weight was 10.8%. Among races, the highest occurrence of low birth weight was in Malay, while the highest age group was between 21 years old to 34 years old with majority of the respondent were married. Among the maternal socio-demographic factors, maternal height of less than 150 cm has a significant relationship with low birth weight. In addition, maternal weight of 45 kg and less and maternal weight gain during pregnancy of less than 10 kg were also found to be risk factors. However, none of the socio-demographic factors were significantly associated with low birth weight deliveries. Similarly, signs of premature delivery, maternal vaginal bleeding and fetal growth retardation (IUGR had a significant association.Conclusion: The mothers that have experienced any of the risks that were identified should be monitored and effective prevention should be taken to decrease the chances of low birth weight but not forgetting to promote a health lifestyle to the mother and father as well.

    Full Text Available Background: the low birth weight still constitutes a complex a complex health problem. It is determined by some factors and it is the most important predictive index of infantile mortality. Objective: identifying the risk factors related to low birth weight. Methods: a descriptive study was conducted. There were analyzed the 77 birth of children with inferior weigh to 2500g, occurred in 2010 at the municipality of Cienfuegos, puerperas were included, mothers of those children. The pregnancy's follow-up cards, patient’s clinical records and municipal and provincial statistics were checked. In addition to the socio-demographic characteristics, the nutritional state, numbers of pregnancies, heavy profit during pregnancy, age, toxic habits and diseases correlated to pregnancy were analyzed. Results: the index of low birth weigh oscillated between 3.6 and 6.7 per month. The 52% of low birth weight newborn’s mothers had school university level. The 74 % of mothers work. The 70.1 % were smokers and the 57, 1 % developed a gravidum hypertensive disease. Conclusions: the most associated factors to low birth weight were, the mother’s habit to smoke, as well as the diseases that affected them during pregnancy, fundamentally the hypertensive disease and the vaginal sepsis.

    Full Text Available Epidemiologic evidence provides some support for a causal association between maternal secondhand smoke (SHS exposure during pregnancy and reduction in infant birth weight. The purpose of this cross-sectional study is to examine the magnitude of this association in China, where both prevalence and dose of SHS exposure are thought to be higher than in U.S. populations. Women who gave birth in Beijing and Changchun September 2000–November 2001 were interviewed to quantify self-reported prenatal SHS exposure. Their medical records were reviewed for data on pregnancy complications and birth outcomes. Non-smoking women who delivered term babies (≥37 weeks gestation were included in the study (N = 2,770. Nearly a quarter of the women (24% reported daily SHS exposure, 47% reported no prenatal exposure, and 75% denied any SHS exposure from the husband smoking at home. Overall, no deficit in mean birth weight was observed with exposure from all sources of SHS combined (+11 grams, 95% CI: +2, +21. Infants had higher mean birth weights among the exposed than the unexposed for all measures of SHS exposure. Future studies on SHS exposure and infant birth weight in China should emphasize more objective measures of exposure to quantify and account for any exposure misclassification.

    The purpose of this study was to examine predictors of neurodevelopmental outcome in very low birth weight children without major impairment at 5 years of age, as well as to identify the contribution of early neurodevelopmental assessment to preterm children's later developmental outcomes. The participants in this study included 126 children who were prematurely born with very low birth weight. Outcomes of the childrens' later development were measured in tests that factored cognitive function, motor performance, and adaptive behavior. The results indicated that more than 50% of full-scale intelligence and 30% of both motor performance and adaptive behavior at the age of 5 can be explained by four predictors. The four predictors include preterm children's medical complications at birth, maternal education, early motor assessments, and cognitive assessments. Adding each test score obtained in early ages provides additional information to predict children's cognitive, motor, and adaptive behavior at 5 years of age. Manifold assessments conducted in multiple time periods strengthen the predictive values of later developmental outcomes. In addition, the findings of this study indicate that very low birth weight children tend to have lower adaptive behavior at 5 years old. With regard to our findings, we believe that having adaptive function is a reflection of a child's overall integrated abilities. Further study is warranted to increase understanding of this topic, as well as to be able to predict adaptive strengths and weakness and pinpoint limiting factors that may be useful for targeting behaviors in intervention.

    Back ground Anemia in pregnancy is associated with increased rates of maternal and perinatal mortality, premature delivery, low birth weight, and other adverse outcomes Materials and Methods A prospective study was conducted on 1405 Iranian pregnant women who delivered during 2015. Blood was collected from all the subjects to measure the hemoglobin (Hb) during 16-19 weeks, 22-24 weeks, and 34-36 weeks of gestation. According to the level of hemoglobin, it is divided into 4 groups. Group 1; Hb > 10.1 gm/100ml (control group), Group 2; Hb= 8.1-10 gm/100ml (mild anemia) Group 3; Hb= 6.5-8 gm/100ml (moderate anemia) Group 4; Hb 10 g/dl), considered as normal gave birth to heavier and normal babies (3.3 kg). The severity of anemia during three trimesters was closely associated with birth weight of newborns. Conclusion The low hemoglobin values during three trimesters of pregnancy were associated with low birth weight in Iran. The anemia can lead to intra uterine growth retardation. PMID:26985354

    Full Text Available INTRODUCTION. The incidence of multiple births has increased in the last decade. Perinatal mortality in triplets is significantly greater than in twin and singleton births. OBJECTIVE. The objective of this study was to describe the extent of birth weight discordance among triplets and to identify its association with an increased risk of perinatal mortality. METHOD A retrospective analysis of triplet births, for the period 1993-2003, was conducted at the Gynaecological-Obstetric Clinic "Narodni Front" in Belgrade. Birth weight discordance was defined as the difference in birth weight between the largest and the smallest triplet's weight of more than 20%. RESULTS. The rate of triplets has increased by almost 75% between the first (7.7% and the last (29.6% 5-year period of the last decade. Triplets are becoming more common because of the frequent use of assisted reproductive technology as a treatment for infertility. In the period 1993-2003, there were a total of 40 triplet live births (24 weeks and greater with incidence of 0.06%. There was no clear association between maternal age, parity, method of conception, birth gestational age, and disorders complicating pregnancy with birth discordance more than 20%. Regarding birth weight groups, statistical significance occurred only in the <999 grams group for discordant and in the 2000-2499 grams group for concordant triplets. Overall, the perinatal mortality rate in the group was 10.8%, the foetal mortality rate was 1.7% (2/120, and the neonatal (0-28 days mortality rate was 9.1% (11/120. An odds ratio of 95% confidence interval shows 3 times greater risk for adverse perinatal outcome in the discordant group. However, the difference was not significant. CONCLUSION. Increasing birth weight discordance may increase the risk of adverse perinatal outcome. Triplet pregnancies, being high risk, require intensive antenatal care in order to prevent preterm delivery and ultrasound in order to diagnose foetal

    This study examines the extent to which the relationship between area socioeconomic position (SEP) and low birth weight (LBW) varies by race and ethnicity. A cross-sectional, secondary data analysis was performed with 1992-1994 Vital Statistics and 1990 U.S. Census data for selected metropolitan areas. Low birth weight (poverty was defined as poor persons living in neighborhoods with 40% or more poverty in metropolitan areas. The results showed that the relationship between concentrated poverty and LBW varied by race and ethnicity. Concentrated poverty was significant for Latinos, even when controlling for maternal health and MSA-level factors. By contrast, maternal health characteristics, such as pre-term birth, teen birth and tobacco use, explained much of the variance in African-American and White LBW These findings extend the discussion about race, class, and health disparities to include Latinos and shows how the relationship between SEP and LBW can vary within an ethnic group.

    2002-09-01

    The differences between adolescents born pre-term (n = 50) and a matched sample of adolescents born full-term were examined in relation to fear of personal death, attachment styles, and the relation between the two variables. Findings revealed that adolescents born pre-term showed a higher level of fear of personal death and a lower frequency of secure attachment style than adolescents born full-term. In addition, secure full-term born adolescents exhibited a lower level of fear of personal death compared with insecure adolescents; whereas among those born pre-term, attachment styles did not affect the level of fear of personal death. Results are discussed in terms of the long-term impact of premature birth on affect regulation in adolescence.

    Full Text Available Objective: The purpose of this study was to determine the risk factors which predispose to the development of high grade IVH (grade 3 and 4 in very low birth weight infants. Material & Methods: In a retrospective case control clinical study files of all premature infants with birth weights less than 1500 grams admitted between April 2004 and Oct 2005 to the neonatal intensive care unit of Akbar Abadi hospital in Tehran were reviewed. 39 infants with IVH grade 3 and 4 were identified. A control group of 82 VLBW infants matched for gestational age and birth weight were selected. Prenatal data, delivery characteristics, neonatal course data and reports of cranial ultrasonography were carefully collected for both groups. Those variables that achieved significance (p<0.05 in univariate analysis entered to multivariate logistic regression analysis. Findings: A total of 325 VLBW infants were evaluated. Mortality rate was 21.5%. Of the remaining the incidence of high grade IVH was 15.5%. Multivariate logistic analysis showed that following factors are associated with greater risk of high grade IVH occurrence: Low gestational age (OR: 3.72; 95% CI: 1.65-8.38, low birth weight (OR: 3.42; 95% CI: 1.65-8.38, low Apgar score at 5 minute (OR:1.58; 95% CI:1.59-6.32, hyaline membrane disease (HMD, OR: 3.16; 95% CI: 1.42-7.45 and maternal tocolytic therapy with magnesium sulfate (OR: 4.40; 95% CI: 1.10-24.5. Conclusion: Our results showed that maternal tocolytic therapy, mechanical ventilation, low gestational age, low birth weight, apnea, and low 5 minute Apgar score increased the risk of major IVH.

    早产是导致围生儿发病和死亡的重要原因,因此研究早产预测及防治方法具有重要的临床意义.目前国内外对早产的预测研究较多,多项预测指标联合应用对早产预测临床意义较大.早产的治疗方法也越来越多,但药物治疗的效果存在争议.由于医学干预早产儿的死亡仍较难避免,因此国内外学者把目光投向早期早产预测,现就对早产有一定临床指导意义的预测指标以及治疗予以综述.%Preterm birth is a major cause of perinatal morbidity and mortality, therefore it is of great clinical significance in researching the forecast and prevention methods of preterm birth. At present,a lot of researches on preterm birth prediction are going on in China and abroad, and combined application of multiple prediction indexes has great clinical significance. Treatments of preterm birth are becoming more and more,but the medication treatment effect is still controversial. Premature death due to medical intervention is still difficult to avoid, therefore scholars in China and abroad are turning their attention to early prediction of preterm labor. Here is to make a review on the prediction indexes and treatments of a certain clinical significance.

    Full Text Available Abstract Background Few studies of the association between psychiatric disorder and premature death have adjusted for key confounders and used structured psychiatric interviews. We aimed to investigate if psychiatric disorder was associated with a higher risk of mortality and whether any excess mortality was due to suicide, or explained by other health or socioeconomic risk factors. Methods We used data from the MRC National Survey of Health and Development, a nationally representative UK birth cohort. 3283 men and women completed the Present State Examination at age 36. The main outcome measure was all-cause mortality before age 60. Results Those with psychiatric disorder at age 36 had a higher risk of death even after adjusting for potential confounders (Hazard ratio = 1.84, 95% C.I. 1.22-2.78. Censoring violent deaths and suicides led to similar results. Conclusions Psychiatric disorder was associated with excess premature mortality not explained by suicide or other health or socioeconomic risk factors.

  17. Long-term respiratory consequences of premature birth at less than 32 weeks of gestation.

    Chronic respiratory morbidity is a common adverse outcome of very premature birth, particularly in infants who had developed bronchopulmonary dysplasia (BPD). Prematurely born infants who had BPD may require supplementary oxygen at home for many months and affected infants have increased healthcare utilisation until school age. Chest radiograph abnormalities are common; computed tomography of the chest gives predictive information in children with ongoing respiratory problems. Readmission to hospital is common, particularly for those who have BPD and suffer respiratory syncytial virus lower respiratory infections (RSV LRTIs). Recurrent respiratory symptoms requiring treatment are common and are associated with evidence of airways obstruction and gas trapping. Pulmonary function improves with increasing age, but children with BPD may have ongoing airflow limitation. Lung function abnormalities may be more severe in those who had RSV LRTIs, although this may partly be explained by worse premorbid lung function. Worryingly, lung function may deteriorate during the first year. Longitudinal studies are required to determine if there is catch up growth. © 2013 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Background: Low Birth Weight (LBW babies run a higher risk of morbidity and mortality in the perinatal period. However, in our country where almost 70-80% births take place at home and peripheral hospitals, taking accurate weight is a problem due to unavailability of weighing scale and trained personnel. Hence there is a constant search for newer methods to detect LBW babies so that early interventions can be instituted. Various authors have used different surrogate anthropometric measurements from different parts of our country. In the present study, an attempt was made to validate the feasibility of using calf circumference as a predictor of LBW babies that can be used by a trained or untrained person. Objectives: To study various anthropometric measurements including calf circumference in newborns and to correlate various measurements with birth weight. Methods: The present study was conducted in the department of Social & Preventive Medicine, MLB Medical College, Jhansi (UP for a period of one year. The study included 1100 consecutively delivered neonates in the maternity ward of MLB Medical College Hospital, Jhansi (UP. The birth weight (Wt, crown heel length (CHL, crown rump length (CRL, head circumference (HC, chest circumference (CC, mid arm circumference (MAC, thigh circumference (TC and calf circumference (CC by standard techniques. All the measurements were taken by a single person throughout the study period with in 24 hours of delivery. Standard statistical methods were adopted for determination of critical limit, sensitivity, specificity and correlation coefficient of different anthropometric measurements in relation to birth weight. Results: Analysis of data indicates that out of 1100 newborns, 55.64% were low birth weight. The percentage of newborns > 2500gm was 44.36. Overall average birth weight was 2348 ± 505gm. Out of 1100 newborns, 608 (55.27% were males and 492 (44.73% were females. Average birth weight for males was 2412

    The hearing of 98 perinatal intensive care survivors with a mean birth weight of 1,540 g was assessed at a mean age of 6 1/2 years. They represented 73% of the long-term survivors with birth weights of 1,800 g or less who had been cared for in our neonatal unit during the three-year period 1971 through 1973. Nine of the 98 infants had sensorineural hearing loss, and 14 had exudative otitis media. During their neonatal period, the infants with hearing loss experienced more frequent apneic attacks, hyperbilirubinemia (serum bilirubin level, greater than 14 mg/dL), and hypothermia compared with their healthy counterparts. There was no evidence that the duration of stay in the incubator or the use of stay in the incubator or the use of ototoxic drugs had affected the hearing of these low-birth-weight infants.

    Full Text Available OBJECTIVE: The objective of this study was to evaluate whether adolescent pregnancy is a risk factor for low birth weight (LBW babies. METHODS: This was a cross-sectional study of mothers and their newborns from a birth cohort in Aracaju, Northeastern Brazil. Data were collected consecutively from March to July 2005. Information collected included socioeconomic, biological and reproductive aspects of the mothers, using a standardized questionnaire. The impact of early pregnancy on birth weight was evaluated by multiple logistic regression. RESULTS: We studied 4,746 pairs of mothers and their babies. Of these, 20.6% were adolescents (< 20 years of age. Adolescent mothers had worse socioeconomic and reproductive conditions and perinatal outcomes when compared to other age groups. Having no prenatal care and smoking during pregnancy were the risk factors associated with low birth weight. Adolescent pregnancy, when linked to marital status "without partner", was associated with an increased proportion of low birth weight babies. CONCLUSIONS: Adolescence was a risk factor for LBW only for mothers without partners. Smoking during pregnancy and lack of prenatal care were considered to be independent risk factors for LBW.

    The purpose of this study is to determine whether the score of the sense of coherence 13-item version (SOC-13) scale in the second trimester of pregnancy is associated with threatened premature birth. All the subjects gave their informed written consent before their participation in the study. A self-reported questionnaire survey was conducted on the pregnant women at approximately 18 weeks of pregnancy. The questionnaire consisted of items on demographic characteristics, perinatal abnormalities, stress perception scale (SPS), and SOC-13 scale. Approximately 30 weeks of pregnancy after the first survey, we surveyed whether any treatment had been provided for threatened premature birth during the course of the current pregnancy. The study period was from December 2007 to February 2010. One hundred and seventy-seven pregnant women participated in the study, but only the data from 151 pregnant women were analyzed. Forty-three (28.5%) pregnant women had threatened premature birth and received some treatment. Logistic regression analysis was carried out with threatened premature birth as the dependent variable and age, childbirth history, smoking habit, history of miscarriage or premature birth in previous pregnancies, SPS score, and SOC-13 scale score as the independent variables. It was shown that SOC-13 scale score affected threatened premature birth (p premature birth. This study suggests that the SOC-13 scale score in the second trimester of pregnancy could be of great value in clinical health care of pregnant women with a risk of threatened premature birth in the subsequent course of pregnancy.

    Full Text Available The newborn's weight at birth is an important measure for newborn's health in all communities. Among developed countries, 70 percent of low birth weight (LBW newborns are preterm. The corresponding figure for undeveloped countries is only 30 percent, there are also evidence of intra-uterine growth retardation among these countries. Among effective factors on LBW, maternal related factors have important role in promotion and improvement of infants and mother's health. This study is a descriptive-analytic one and was conducted cross-sectionally through a questionnair. The study population determined by simple random sampling from newborns under coverage of urban health centers in Kohgiloye and Boyerahmad province. Necessary data collected from existing medical and health records filed in the health centers. Among 285 newborns, 88.4 percent considered with normal weight, 4 percent with IBW and 11.6 percent with more than normal weight. 7.4 percent of cases were immature. 85.3 percent of the mothers in study population were in immune range of age for pregnancy and 7.6 percent of them were illiterate. Except the sex of newborn (P=0.0008 and gestational age at birth (P<0.001 none of the variables demonstrated a significant statistical relation with the birth weight. The results of this study confirm other research's findings and reveal that with improving material factors such as mother's age, employment and literacy, the factors which are effective on birth weight, will be dependent on physiological factors such as sex of newborn and gestational age at birth.

    Full Text Available Birth weight of a child is an important indicator of its vulnerability for childhood illness and chances of survival. A large number of infant deaths can be averted by appropriate management of low birth weight babies and prevention of factors associated with low birth weight. The prevalence of low birth weight babies in Nepal is estimated to be about 12-32%.Our study aimed at identifying major determinants of low birth weight among term babies in Nepal. A hospital-based retrospective case control study was conducted in maternity ward of Tribhuvan University Teaching Hospital from February to July 2011. A total of 155 LBW babies and 310 controls were included in the study. Mothers admitted to maternity ward during the study period were interviewed, medical records were assessed and anthropometric measurements were done. Risk factors, broadly classified into proximal and distal factors, were assessed for any association with birth of low-birth weight babies. Regression analysis revealed that a history of premature delivery (adjusted odds ratio; aOR5.24, CI 1.05-26.28, hard physical work during pregnancy (aOR1.48, CI 0.97-2.26, younger age of mother (aOR1.98, CI 1.15-3.41, mothers with haemoglobin level less than 11gm/dl (aOR0.51, CI0.24-1.07 and lack of consumption of nutritious food during pregnancy (aOR1.99, CI 1.28-3.10 were significantly associated with the birth of LBW babies. These factors should be addressed with appropriate measures so as to decrease the prevalence of low birth weight among term babies in Nepal.

    Adiposity in pre- and postnatal life may influence menarcheal age. Existing evidence is primarily cross-sectional, failing to address temporality, for which the role of adiposity in early life remains unclear. The current study sought to systematically review longitudinal studies evaluating the associations between birth weight and infant/childhood weight status/weight gain in relation to menarcheal age. PubMed, EMBASE, Web of Science, Global Health (Ovid) and CINAHL were systematically searched. Selected studies were limited to English-language articles presenting multi-variable analyses. Seventeen studies reporting risk estimates for birth weight (n = 3), infant/childhood weight gain/weight status (n = 4) or both (n = 10), in relation to menarcheal age were included. Lower vs. higher birth weight was associated with earlier menarche in nine studies and later menarche in one study, while three studies reported a null association. Greater BMI or weight gain over time and greater childhood weight were significantly associated with earlier menarche in nine of nine and six of seven studies, respectively. Studies suggested that lower birth weight and higher body weight and weight gain in infancy and childhood may increase the risk of early menarche. The pre- and postnatal period may thus be an opportune time for weight control interventions to prevent early menarche, and its subsequent consequences. © 2017 World Obesity Federation.

    With more and more extreme premature and very low-birth weight babies being resuscitated, umbilical central venous catheterisation is now being used more frequently in neonatal intensive care. One of the life-threatening complications is pericardial effusion and cardiac tamponade; however, it is potentially reversible when it is caught in time. The authors present a case of cardiac tamponade following umbilical venous catheterisation in a neonate. The patient was diagnosed at the appropriate time by echocardiography and urgent pericardiocentesis proved lifesaving.

Methods Data of 268 patients (group A) with premature birth were analyzed. Another 268 full-term parturients (group B) in the same period were randomly selected as the controls. The risk factors such as gestation and birth, antenatal care and complications of pregnancy were compared between two groups. Results The number of induced abortion and without regular routine prenatal tests were the premature birth-related factors. There were 124 cases(46. 2%) with a histry of induced abortion, of whom 60 cases(22. 4%) underwent induced abortion for ≥ twice in group A. There were 99 cases (36. 9%) with a histry of induced abortion,of whom 30 cases(11. 2%) underwent induced abortion for≥ twice in group B. The differences were significant between two groups(P<0. 05). The high risk factors for premature birth were preterm premature rupture of membrane, preeclampsia, multiple pregnancy and abnormal position of fetus. Conclusion Premature birth is caused by many factors. Attention should be paid to the prepartal examination and perinatal care for reducing the rate of premature birth.

    Full Text Available Background: The mothers of premature infants are at risk of psychological stress because of separation from their infants. One of the methods influencing the maternal mental health in the postpartum period is kangaroo mother care (KMC. This study was conducted to evaluate the effect of KMC of low birth weight infants on their maternal mental health. Materials and Methods: The study was conducted in the Department of Pediatrics of Isfahan University of Medical Sciences, Isfahan, Iran. Premature infants were randomly allocated into two groups. The control group received standard caring in the incubator. In the experimental group, caring with three sessions of 60 min KMC daily for 1 week was practiced. Mental health scores of the mothers were evaluated by using the 28-item General Health Questionnaire. Statistical analysis was performed by the analysis of covariance using SPSS. Results: The scores of 50 infant-mother pairs were analyzed totally (25 in KMC group and 25 in standard care group. Results of covariance analysis showed the positive effects of KMC on the rate of maternal mental health scores. There were statistically significant differences between the mean scores of the experimental group and control subjects in the posttest period (P < 0.001. Conclusion: KMC for low birth weight infants is a safe way to improve maternal mental health. Therefore, it is suggested as a useful method that can be recommended for improving the mental health of mothers.

    We tested the hypothesis that at high altitude birth weight decreases once a critical barometric pressure (Pb) is reached. Birth weight data covering the 1-year period from November 1997 to October 1998 were collected in Peru from the data files of 15 community and mining centers between sea level and 4575 m altitude. These centers are scattered along the main road that joins Lima (on the Pacific shore) to Cerro de Pasco (4330 m) and surroundings. Above approximately 2000 m (ie, at Pb below approximately 590 mm Hg, inspired O(2) partial pressure of approximately 114 mm Hg) and up to approximately 4500 m altitude birth weight declined at an average of 65 g for every additional 500 m altitude (or 105 g for every additional 50 mm Hg drop in Pb). This pattern did not differ between sexes. Averages and modal distributions of the birth weight from 2 hospitals in Cerro de Pasco (4330 m) serving different social groups were similar. Body length at birth was similar at various altitudes, with the exception of the 2 highest locations above 4500 m, where it was slightly reduced. From these data, together with additional data collected in the North of Peru (Chacas, 3360 m) and with results from other ethnic groups previously published, we conclude that the drop in birth weight at altitude is (1) apparent once the critical Pb of approximately 590 mm Hg is reached, corresponding to an altitude of approximately 2000 m, (2) proportional to the increase in altitude between approximately 2000 m and 4500 m, and (3) independent from socioeconomic factors.

    Aim: To assess the effect of various maternal characteristics in diabetic pregnancies on birthweight (BW) taking into account birthweight of an elderly sibling.  Method: We identified all pregnant diabetic women in North Jutland County. Birthweight and certain maternal characteristics including H...... for various increments in each of the 9 variables are seen in the table. All significant values are in bold face.  Conclusion: Weight of sibling is a very strong predictor of birthweight attenuating the predictive power of all other variablesapart from gestational age....... adjusted for age and sex using a Danish reference. E.g. an observed sibling weight of 3800 g with expected BW 3400 g predicts 11.8% extra weight equal to 134 grams (114x11.8) and one extra gestational day predicts an additional weight of 27 grams.  Results: The effects in terms of additional grams in BW...

    Prior to digital radiography it was possible for a radiologist to easily estimate the size of a patient on an analog film. Because variable magnification may be applied at the time of processing an image, it is now more difficult to visually estimate an infant's size on the monitor. Since gestational age and weight significantly impact the differential diagnosis of neonatal diseases and determine the expected size of kidneys or appearance of the brain by MRI or US, this information is useful to a pediatric radiologist. Although this information may be present in the electronic medical record, it is frequently not readily available to the pediatric radiologist at the time of image interpretation. To determine if there was a correlation between gestational age and weight of a premature infant with their transverse chest diameter (rib to rib) on admission chest radiographs. This retrospective study was approved by the institutional review board, which waived informed consent. The maximum transverse chest diameter outer rib to outer rib was measured on admission portable chest radiographs of 464 patients admitted to the neonatal intensive care unit (NICU) during the 2010 calendar year. Regression analysis was used to investigate the association between chest diameter and gestational age/birth weight. Quadratic term of chest diameter was used in the regression model. Chest diameter was statistically significantly associated with both gestational age (P < 0.0001) and birth weight (P < 0.0001). An infant's gestational age and birth weight can be reliably estimated by comparing a simple measurement of the transverse chest diameter on digital chest radiograph with the tables and graphs in our study.

    Accurate automated tissue segmentation of premature neonatal magnetic resonance images is a crucial task for quantification of brain injury and its impact on early postnatal growth and later cognitive development. In such studies it is common for scans to be acquired shortly after birth or later during the hospital stay and therefore occur at arbitrary gestational ages during a period of rapid developmental change. It is important to be able to segment any of these scans with comparable accuracy. Previous work on brain tissue segmentation in premature neonates has focused on segmentation at specific ages. Here we look at solving the more general problem using adaptations of age specific atlas based methods and evaluate this using a unique manually traced database of high resolution images spanning 20 gestational weeks of development. We examine the complimentary strengths of age specific atlas-based Expectation-Maximization approaches and patch-based methods for this problem and explore the development of two new hybrid techniques, patch-based augmentation of Expectation-Maximization with weighted fusion and a spatial variability constrained patch search. The former approach seeks to combine the advantages of both atlas- and patch-based methods by learning from the performance of the two techniques across the brain anatomy at different developmental ages, while the latter technique aims to use anatomical variability maps learnt from atlas training data to locally constrain the patch-based search range. The proposed approaches were evaluated using leave-one-out cross-validation. Compared with the conventional age specific atlas-based segmentation and direct patch based segmentation, both new approaches demonstrate improved accuracy in the automated labeling of cortical gray matter, white matter, ventricles and sulcal cortical-spinal fluid regions, while maintaining comparable results in deep gray matter.

    Full Text Available The purpose of our research is a long-term follow up study of children with low birth weight. Materials and methods. 115 premature children from 0 to 7 years old took part in the research process. The children gestational age was 30-35 weeks and their birth weight was less than 2500 g. All children had thorough clinical and laboratory, instrumental and psychological examination up to the age of seven. Their parents took part in questionnaire survey. Results. Development of all aspects of mentality is retarded and such retardation can be observed in the first months of life as slow learning of new things and peculiarities of psychological interrelations with the world around in the form of negative response to the influence of sensory stimuli, behavioral disorders and difficulties in social adaptation. Conclusion. Children with low birth weight are included into the high-risk group of disabling abnormalities and persistent non-disabling disorders. These children need early comprehensive rehabilitation and, at the same time, extremely careful prognosis of their further development.

  20. Immigration policy and birth weight: Positive externalities in Italian law.

    A decade ago, the political party of the Italian center-right voted a law restricting immigration. The law became effective in early 2005, when the Italian parliament approved the decree for its application, but one of its articles, granting amnesty for illegal immigrant workers, became immediately effective in July 2002. As a result, 650,000 immigrants were granted the status of foreign nationals in Italy. In this paper, we examine whether the increase in the prevalence of "regular immigrants" has led to an improvement in health outcomes of babies born to migrant women, measured in terms of birth weight. Two hitherto unexploited birth sample surveys published by Italian Institute of Statistics were used for this study. Our estimates show that regularized immigration reduced the probability of low birth weight.

    Glutamine, described as a "conditionally essential" amino acid for critically ill patients, has not been routinely added to parenteral amino acid formulations for critically ill neonates and is provided in only small quantities by the enteral route when enteral intake is low. We conducted a blinded, randomized study of enteral glutamine supplementation in 68 very low birth weight neonates randomly assigned to receive glutamine-supplemented premature formula versus premature formula alone between days 3 and 30 of life. Primary end points consisted of hospital-acquired sepsis, tolerance to subsequent enteral feedings (days with no oral intake), and duration of hospital stay. Hospital acquired sepsis was 30% (control group) and 11% (glutamine group). Logistic regression with birth weight as a covariate showed that: (1) feeding group was significant (p = 0.048) in determining the probability of developing proven sepsis over the course of hospitalization and (2) the estimated odds of developing sepsis were 3.8 times higher for infants in the control group than for those treated with glutamine. Glutamine-supplemented infants had better tolerance to enteral feedings as measured by percent of days on which feedings needed to be withheld (mean percentage of 8.8 vs 23.8, p = 0.007). Analysis of T cells demonstrated a blunting of the rise in HLA-DR+ and CD16 subsets in glutamine-supplemented infants. There were no differences in growth; in serum ammonia, urea, liver transaminase, or prealbumin concentrations; or in mean hospital stay. This study provides evidence for decreased morbidity in very-low-birth-weight neonates who receive enteral glutamine supplementation.

    Housing instability is an understudied social condition that may be a severe stressor during pregnancy. Aims of this study are to identify correlates of housing instability and to explore the association between housing instability and birth weight among pregnant teens and young mothers. Participants included pregnant women ages 14-21 from seven community hospitals and health centers in New York City (N = 623). Data were collected via structured surveys during the second trimester of pregnancy (14 to 24 weeks gestation, M = 19.35, SD = 3.20). Birth weight was obtained through labor and delivery logs. Housing instability was operationalized as two or more moves within the past year. More than one in four (28.5 %) pregnant teens and young women in this sample reported housing instability. Women who reported housing instability were less likely to be enrolled in school, have parents as main source of financial support, live in a single-family home or apartment, or be food secure; they were more likely to smoke (all p < 0.05). After adjusting for important clinical, behavioral, and demographic factors typically associated with lower birth weight, housing instability remained a significant predictor of lower birth weight (B (SE) = -83.96(35.47), p = 0.018). Results highlight the importance of housing stability during pregnancy for infant health. Future interventions and policies should ensure that women are housing stable before, during, and after pregnancy.

    The prevalence of low birth weight (LBW) is a major public health issue in India (30.0%) and is the highest among South-Asian countries. Maternal autonomy or the mother's status in the household indicates her decision-making power with respect to movement, finance, healthcare use, and other household activities. Evidence suggests that autonomy of the mother is significantly associated with the child's nutritional status. Although previous studies in India reported the determinants of LBW, literature on the association between mother's autonomy and birth weight are lacking. This study, therefore, aims to examine the influence of maternal autonomy on birth weight of the newborn. The study, a secondary data analysis, examined data from the 2005-2006 National Health and Family Survey (NFHS 3) of India. A maternal autonomy score was created through proximal component factor analysis and categorized as high, medium, and low autonomy levels. The main outcome variable included birth weight of the index child obtained from health cards and mother's recall. Descriptive and logistic regression analyses were performed. Results from the study indicate that 20.0% of the index children included in the analysis were born at LBW. Low maternal autonomy was an independent predictor of LBW (odds ratio [OR] 1.28, 95% confidence interval [CI] 1.07-1.53, p=0.007) after adjusting for other factors, and medium autonomy level was not significant. These findings clearly indicate the importance of empowering women in India to combat the high incidence of LBW.

    2012-01-01

    Full Text Available Abstract Background Healthy infants typically regain their birth weight by 21 days of age; however, failure to do so may be due to medical, nutritional or environmental factors. Globally, the incidence of low birth weight deliveries is high, but few studies have assessed the postnatal weight changes in this category of infants, especially in Africa. The aim was to determine what proportion of LBW infants had not regained their birth weight by 21 days of age after discharge from the Special Care Unit of Mulago hospital, Kampala. Methods A cross sectional study was conducted assessing weight recovery of 235 LBW infants attending the Kangaroo Clinic in the Special Care Unit of Mulago Hospital between January and April 2010. Infants aged 21 days with a documented birth weight and whose mothers gave consent to participate were included in the study. Baseline information was collected on demographic characteristics, history on pregnancy, delivery and postnatal outcome through interviews. Pertinent infant information like gestation age, diagnosis and management was obtained from the medical records and summarized in the case report forms. Results Of the 235 LBW infants, 113 (48.1% had not regained their birth weight by 21 days. Duration of hospitalization for more than 7 days (AOR: 4.2; 95% CI: 2.3 - 7.6; p value Conclusion Failure to regain birth weight among LBW infants by 21 days of age is a common problem in Mulago Hospital occurring in almost half of the neonates attending the Kangaroo clinic. Currently, the burden of morbidity in this group of high-risk infants is undetected and unaddressed in many developing countries. Measures for consideration to improve care of these infants would include; discharge after regaining birth weight and use of total parenteral nutrition. However, due to the pressure of space, keeping the baby and mother is not feasible at the moment hence the need for a strong community system to boost care of the infant. Close

    Full Text Available Objective: The present study has been conducted to investigate the role of plasma homocysteine on neonatal birth weight.Methods: This prospective cross sectional analytical study was conducted in the inpatient department of obstetrics & gynecology, Dhaka Medical College Hospital on 120 term, singleton pregnant women. Pregnant women with plasma total bomocysteine >15 µmol/L were termed as having hyperhomocysteinemia (case, n = 25, while women with plasma total homocysteine ≤15 µmol/L were considered as notmal (control, n = 95. Neonatal birth weight was the main outcome variable which was compared between case and control groups. Result: The entire women in the case group were in their 3rd decades, while 80% of the control group were in this age range and 10% was below 20 and 10% above 30 years old. The cases were older than the controls (25.6 ± 2.0 vs. 23.7 ± 4.7 years, p = 0.051 . Over three-quarters (76% of the cases were SSC level educated, while majority (84.2% of the controls was primary level educated. Eighty percent of the neonates born of mothers with hyperhomocysteinemia were of low birth weight as opposed to only 9.5% in the control group. The mothers of case-group carry nearly 40(95% of CI= 11.5 - 126.4 times higher risk of having low birth weight babies than the mothers with nonnal homocysteine level. The mean birth weight of neonates of case group was observed to be significantly higher (2.8 ± 0.4 kg than that of control group (2.2 ± 0.4 kg. Correlation between the two variables shows that as plasma homocysteine level of women increases the birth weight of neonates decreases bearing an inverse relationship between these two variables (r = - 0.326, p < 0.001 . Conclusion: Pregnant women with elevated plasma total homocysteine carry much higher risk of giving low birth weight babies than the women with normal or low level of total homocysteine. Thus, measuring total homcysteine during pregnancy is of much clinical importance as

  13. Low Birth Weight due to Intrauterine Growth Restriction and/or Preterm Birth: Effects on Nephron Number and Long-Term Renal Health

    Directory of Open Access Journals (Sweden)

    Vladislava Zohdi

    2012-01-01

    Full Text Available Epidemiological studies have clearly demonstrated a strong association between low birth weight and long-term renal disease. A potential mediator of this long-term risk is a reduction in nephron endowment in the low birth weight infant at the beginning of life. Importantly, nephrons are only formed early in life; during normal gestation, nephrogenesis is complete by about 32–36 weeks, with no new nephrons formed after this time during the lifetime of the individual. Hence, given that a loss of a critical number of nephrons is the hallmark of renal disease, an increased severity and acceleration of renal disease is likely when the number of nephrons is already reduced prior to disease onset. Low birth weight can result from intrauterine growth restriction (IUGR or preterm birth; a high proportion of babies born prematurely also exhibit IUGR. In this paper, we describe how IUGR and preterm birth adversely impact on nephrogenesis and how a subsequent reduced nephron endowment at the beginning of life may lead to long-term risk of renal disease, but not necessarily hypertension.

Fasting individuals abstain from drinking liquids and eating foods. Manypregnant women and gynecologists are concerned about the possible complicationsassociated with fasting and effects on fetal health. The aim of this study was to determine the effect of Ramadan fasting on neonatalbirth weight.Materials and Methods: The current historical cohort study was performed on pregnant women attending maternity hospitals in Kashan in 2008. Twofasting and non-fasting groups were compared. Multiple pregnancies and gestational age less than 37 weeks were considered as the exclusion criteria. In fasting and non-fasting groups, age, parity, gestational age, body mass index (BMI, mother's occupation, prenatal care attendance and intended or unintended pregnancy were matched. For the statistical analysis of the data, covariance analysis and SPSS v16.0 were used. Results: In this study, 293 cases were evaluated among whom 31.7% did notfast. In the two groups, the mean age, gestational age, parity and weight gain during pregnancy were not significantly different. The mean birth weight was 3338 g (±498 g and 3343 g (± 339 g in fasting and non-fasting groups respectively. The results showed that the mean birth weight of the neonates in fasting and non-fasting groups was not significantly different (p=0. 931 Conclusion: The results of this study indicated that there is no significant relationship between the neonatal birth weight and maternal fasting during pregnancy. Therefore we declare thatfasting for pregnant women who receive prenatal care has no effects on neonatal birth weight.

    2011-05-01

    Among obstetricians and neonatologists in administrative roles in New York City hospitals, a survey was initiated to compare the physicians' definitions of live birth and fetal death, the gestational age at which they consider infants viable, and the resuscitation practices of the neonatologists. The target survey population was 34 neonatologists, and 39 obstetricians representing 41 of the City's 43 maternity hospitals. A telephone survey was used to gather qualitative data from the physicians regarding their definitions of live birth, fetal death, and viability, and their practices regarding extremely premature births. Surveys were completed for 58 physicians, a response rate of 79% (94% for neonatologists and 67% for obstetricians). Physicians' definitions of live birth and fetal death varied, with almost a third (29%) of physicians including gestational age as part of their live birth criteria. Most of the physicians (90%) consider infants born at ≥23 weeks gestation viable. Most neonatologists (97%) said they always resuscitate infants born at ≥23 weeks gestation, and most (94%) said they would never resuscitate infants born at death. Whereas reporting requirements are based on definitions of live birth and fetal death, physicians make resuscitation and other clinical decisions regarding extremely premature infants based on definitions of viability.

    Background: Invasive fungal infections cause excessive morbidity and mortality in premature neonates and severely ill infants. Methods: Safety and efficacy outcomes of micafungin were compared between prematurely and non-prematurely born infants premature [birth weight (BW) premature, received ≥1 dose of micafungin. Among premature patients, 14.5% were low BW (1500–2499 g), 36.4% very low BW (1000–1499 g) and 49.1% extremely low BW (premature)] died. Significantly more non-premature than premature patients discontinued treatment (P = 0.003). Treatment-related adverse events were recorded in 23% of patients with no difference between groups. More extremely low BW (n = 4, 15%) and very low BW (n = 8, 40%) infants experienced treatment-related adverse events than low BW (n = 0) and there was no relation to micafungin dose or duration. For a subgroup of 30 patients with invasive candidiasis, treatment success was achieved in 73% in both premature and non-premature groups. Prophylaxis was successful in 4/5 non-premature hematopoietic stem cell transplant patients. Conclusion: Micafungin has a safe profile in premature and non-premature infants with substantial efficacy. PMID:24892849

    Full Text Available BACKGROUND Daily we see lots of still birth cases and the agony associated with it after carrying the fetus for so many months with the negative outcome it is quite disheartening. Malnutrition is quite rampant in the country as far as the females are concerned and in the name of the religion and rituals, it complicates the issue further. If the mother is malnourished, the chance of low birth weight baby is high. OBJECTIVES To correlate the prevalence of cardiac anomalies in low birth weight fetuses. MATERIAL AND METHOD The study was carried out in 40 stillbirth fetuses with detailed account of nutritional status of the mother, consanguinity, history of previous pregnancies, miscarriages, socio-economic status and exposure to drugs/radiation. The number of cases with fetus having cardiac anomalies was quite significant. RESULTS Out of total 40 stillbirth fetuses, 29 (72.5% stillbirths were from less than 2.5kg and 11 (27.5% were from more than 2.5kg. Cardiac anomalies were present in 16 and 02 cases respectively. Fused heart-01, mesocardia-01, Dextrocardia with CORV-02, Interrupted aortic arch-02, Abnormal origin of right subclavian artery-01, Tetralogy of Fallot-01, VSD-07, ASD-01, transposition of great vessels-01, persistent truncus arteriosus with tricuspid atresia, elongated hypertrophied abnormally positioned Rt. Atrium, rudimentary Rt. Ventricle-01, mal-attachment of ductus arteriosus-03, double superior vena cava-01, dilated caval system-01. CONCLUSION Considering the high incidence of cardiac anomalies in fetuses of low birth weight, we must try to create awareness and support the expectant mothers to avoid the low birth weight babies and thus the congenital anomalies.

    Full Text Available Objective: Proper nutrition during pregnancy is essential for optimal fetal growth. Investigation of the relation between pregnancy weight gain and birth weight in rural regions of Rasht, center of Guilan Province in Iran, was the purpose of this study. Methods: In this cohort study, prenatal data of 918 women who attended local health centers with singleton term pregnancies were recorded. Maternal demographic characteristics, anthropometric measurements, total pregnancy weight gain and birth weight were recorded by health workers. The women were stratified based on their pre-pregnancy body mass index (BMI into four groups: underweight women, women with normal weight, overweight women and obese women. The relation between weight gain and low birth weight (LBW, birth weight <2500 g and macrosomia (birth weight >4000 g was studied in these four groups. Data were analyzed using Chi-square test, independent t-test, Pearson correlation and logistic regression with 95% confidence intervals. Findings: More than 50% of underweight women and women with normal weight and almost 30% of overweight and obese women gained weight less than what is mentioned in the Institute of Medicine (IOM recommendations. The incidence rate of LBW was 7.1% and that of macrosomia was 5%. Mean weight gain of women with LBW was significantly less than mean weight gain of women who had an infant with a birth weight more than 2500 g (P=0.002. Women who gained weight less than the recommended range had higher rate of LBW in their infants (P=0.01 and the incidence of macrosomia in women with a weight gain above the recommended weight was higher than that in others (P=0.012. Pregnancy weight gain less than what is mentioned in the IOM guideline was the only predictor for LBW (OR=2.79, CI=1.16-6.73, P=0.02. Conclusion:Pregnancy weight gains less than what is mentioned in the IOM recommendation was a significant predictor of LBW, regardless of pre-pregnancy BMI.

    This study evaluated poor weight gain as a risk factor for infants who required treatment for retinopathy of prematurity (ROP), by comparing those born before and after the implementation of higher oxygen saturation (SpO2 ) targets at the Queen Silvia Children's Hospital, Gothenburg, Sweden. We compared infants born at less than 31 weeks, who were screened and, or, treated for ROP: 127 in 2011-2012 when SpO2 targets were 88-92% and 142 in 2015-2016 when they were 91-95%. The subjects were reviewed for birth characteristics, weekly weight and ROP treatment. Data were analysed using the weight, insulin-like growth factor-1, neonatal, ROP (WINROP) prediction tool. The 2011-12 infants who needed ROP treatment (12.6%) had significantly poorer postnatal weight gain than those who did not, but this was not seen in the treated (17.6%) and non-treated ROP groups in 2015-2016. WINROP sensitivity decreased from 87.5% in 2011-12 to 48% in 2015-2016. After the SpO2 target range was increased from 88-92% to 91-95%, postnatal weight gain was no longer a significant risk factor and WINROP lost its ability to predict ROP requiring treatment. Risk factors clearly change as neonatal care develops. This article is protected by copyright. All rights reserved. This article is protected by copyright. All rights reserved.

    Full Text Available Low birth weight (LBW (defined as a birth weight of less than 2500 grams is associated with fetal and neonatal morbidity and mortality, impaired cognitive development, and the advent of chronic diseases in later life. The global incidence of LBW is around 15,5%. The aim of this study was to identify risk factors for low birthweight in the centre of Denizli province. A case-control study was carried out and mothers of 295 newborns with birthweight between 1500-2499 g (cases and 302 newborns with birthweight between 2500-4000 g (controls were analyzed. The questionnare was applied to women using face to face technics between July,2009 and June,2010 . The questionnare included birth weight and birth lenght of newborn, the date of last pregnacy and type of last delivery, profile of mother, anthropometric measures, life styles, habits, addictions, sociodemographic and socioeconomic characteristics of mother and father of newborn. Analysis included frequency and percent distributions, means, standart deviations. In group comparisions for categorical variable, chi square test and odds ratio (OR was used. Logistic regression model was performed for some selected risk factors. P<0.05 was considered statistically significant. Statistical Package for Social Sciences (SPSS program, Version 10 was used for data entry and analysis. When backward logistic regression model was performed for some selected factors in relation to low birth weight, there was a positive relationship between multiple pregnancy [OR(95%CI 18.50 (8.54, 40.39], BMI lower than 20 kg/m2 of mother before pregnancy andemployment status [OR(95%CI 1.98 (1.23, 3.19], weight gain of 7 kg and under during pregnanacy [OR(95%CI 2.49 (1.56, 3.96], a history of giving birth to low birth weight infant [OR(95%CI 3.44 (1.69, 7.02], first- degree and second- degree relative’s histories of giving birth to low birth weight infant [OR(95%CI 4.28 (2.61, 6.94], X- ray exposure in the three months before and

    Smooth muscle cells (SMCs) participate to the regulation of peripheral arterial resistance and blood pressure. To assume their function, SMCs differentiate throughout the normal vascular development from a synthetic phenotype towards a fully differentiated contractile phenotype by acquiring a repertoire of proteins involved in contraction. In human fetal muscular arteries and umbilical arteries (UAs), no data are available regarding the differentiation of SMCs during the last trimester of gestation. The objective of this study was to characterize the phenotype of SMCs during this gestation period in human UAs. We investigated the phenotype of SMCs in human UAs from very preterm (28-31 weeks of gestation), late preterm (32-35 weeks) and term (37-41 weeks) newborns using biochemical and immunohistochemical detection of α-actin, smooth muscle myosin heavy chain, smoothelin, and non-muscle myosin heavy chain. We found that the number of SMCs positive for smoothelin in UAs increased with gestational age. Western blot analysis revealed a higher content of smoothelin in term compared to very preterm UAs. These results show that SMCs in human UAs gradually acquire a fully differentiated contractile phenotype during the last trimester of gestation and thus that premature birth is associated with not fully differentiated contractile SMCs in human UAs.

    Links between low birth weight and tobacco exposure in utero are well established, as are associations between maternal body mass index (BMI) and birth weight. This study further develops those relationships. In particular, this article analyses whether high maternal weight acts to dampen the previously established link between tobacco exposure and low birth weight. A retrospective cohort study was undertaken, reviewing the birth weights of 13,473 live singleton pregnancies born at a Sydney regional hospital between 1998 and 2003. Results demonstrated a statistically significant decline in reduced birth weight as BMI increased. That is, as body weight increases, tobacco use has a smaller effect on reducing birth weight. Inversely, the effect on reducing birth weight for each cigarette smoked by leaner women was greater. In effect, the adverse influence of tobacco use on birth weight appears to be modulated by increasing maternal BMI.

    The aim of the present study was to examine the influence of a supervised and regular program of aquatic activities throughout gestation on maternal weight gain and birth weight. A randomized clinical trial. Instituto de Obstetricia, Ginecología y Fertilidad Ghisoni (Buenos Aires, Argentina). One hundred eleven pregnant women were analyzed (31.6 ± 3.8 years). All women had uncomplicated and singleton pregnancies; 49 were allocated to the exercise group (EG) and 62 to the control group (CG). The intervention program consisted of 3 weekly sessions of aerobic and resistance aquatic activities from weeks 10 to 12 until weeks 38 to 39 of gestation. Maternal weight gain, birth weight, and other maternal and fetal outcomes were obtained by hospital records. Student unpaired t test and χ(2) test were used; P values ≤.05 indicated statistical significance. Cohen's d was used to determinate the effect size. There was a higher percentage of women with excessive maternal weight gain in the CG (45.2%; n = 28) than in the EG (24.5%; n = 12; odds ratio = 0.39; 95% confidence interval: 0.17-0.89; P = .02). Birth weight and other pregnancy outcomes showed no differences between groups. Three weekly sessions of water activities throughout pregnancy prevents excessive maternal weight gain and preserves birth weight. The clinicaltrial.gov identifier: NCT 02602106.

    Full Text Available Objective: Mortality of very low birth weight premature infants is of great public health concern. To better guide local intervention program, it is essential that current and reliable statistics be collected to understand the factors associated with mortality of these infants.Methods: Data of very low birth weight premature infants admitted to a neonatal unit during 2002-2009 was retrospectively collected. Changes in perinatal care between two halves of the study period (2002-2005 and 2006-2009 were identified. Factors associated with in-hospital mortality were found by logistic regression and a predictive score model was established.Findings: A total of 475 cases were enrolled. In-hospital mortality decreased from 29.8% in 2002-2005 to 28.1% in 2006-2009 (P>0.05. More infants born<28 gestational weeks survived to discharge in the latter epoch (38.1% vs 8.3%, P<0.05. Persistent pulmonary hypertension of newborn, pulmonary hemorrhage,birth weight <000 grams, gestational age <33 weeks, feeding before 3 postnatal days and enteral feeding were found predictors of in-hospital mortality by logistic regression. The discriminating ability of the predictivemodel was 82.4% and the cutoff point was -0.56.Conclusion: Survival of very low birth weight premature neonates was not significantly improved in 2006-2009 than 2002-2005. Infants with a score higher than -0.56 were assessed to be at high risk of in-hospital mortality. Multi-center studies of planned follow-up are needed to develop a comprehensive and applicable score system.

    Indomethacin prophylaxis or expectant treatment are common strategies for the prevention or management of symptomatic patent ductus arteriosus (sPDA). To compare the clinical responses of extremely low birth weight (ELBW) infants to indomethacin prophylaxis with that of other infants who were managed expectantly by being treated with indomethacin or surgically only after an sPDA was detected. Retrospective cohort investigation of 167 ELBW infants who received indomethacin prophylaxis (study) and 167 ELBW infants (control) treated expectantly who were matched by year of birth (1999 to 2006), birth weight, gestational age (GA) and gender. Mothers of the two groups of infants were comparable demographically and on the history of preterm labor, pre-eclampsia, antepartum steroids and cesarean delivery. Study and control infants were similar in birth weight, GA, low 5 min Apgar scores, surfactant administration, the need for arterial blood pressure control, bronchopulmonary dysplasia and neonatal mortality. Necrotizing enterocolitis, spontaneous intestinal perforations, intraventricular hemorrhage grade III to IV, periventricular leukomalacia and stage 3 to 5 retinopathy of prematurity occurred also with similar frequency in both groups of infants. In the indomethacin prophylaxis group, 29% of the infants developed sPDA, and of them 38% responded to indomethacin treatment. In the expectantly treated group, 37% developed sPDA, and of them 59% responded to indomethacin treatment. Overall, surgical ligation rate for sPDA was similar between both groups of patients. In our experience, indomethacin prophylaxis does not show any advantages over expectant early treatment on the management of sPDA in ELBW infants. Although no deleterious effects were observed, prophylaxis exposed a significant number of infants who may have never developed sPDA, to potential indomethacin-related complications.

    The aim of this review was to identify the underlying relationship between preterm birth and the development of cardiovascular diseases. Preterm birth significantly affects the elastin content and viscoelastic properties of the vascular extracellular matrix in human arteries. Inadequate elastin synthesis during early development may cause a permanent increase in arterial stiffness in adulthood. Early and permanent alterations in viscoelastic properties may lead to hypertension and cardiovascular disease development in adults born prematurely. ©2014 Foundation Acta Paediatrica.

    In Denmark 30% of females in the reproductive age regularly have shift work. 22 epidemiological papers were studied looking at associations between shift work and abortion, stillbirth, preterm birth, and birth weight. No convincing associations were observed between rotating shift work or fixed nightshift and negative pregnancy outcome. Some epidemiological support was found for a relation between fixed nightshift and late abortions/stillbirth. If fixed night work for all pregnant women is avoided, seven late abortion/stillbirths a year can be prevented. Fixed night work for pregnant women should be avoided.

    Full Text Available The early postnatal weight loss (EPWL is highly variable in the extremely low birth weight infants (birth weight <1000 g, ELBW. It is reported to be unassociated with adverse outcomes within a range of 3- 21% of birth weight. Its wide range might have contributed to this lack of association. The aim of our paper is to study the effects of maximum EPWL, graded as low, medium and large on clinical outcomes in ELBW infants. In a retrospective cohort observational study EPWL was measured as maximum weight loss from birth weight (MWL in ELBW infants and grouped as low (5-12% moderate (18.1-12% and high (18-25%. The clinical course and complications of infants were compared between the groups. Gestational age (GA was highest and surfactant administration, peak inspiratory pressure requirement, fluid intake, urinary output, oxygen dependent days and the number of oxygen dependent infants at age 28 days were lower in the low MWL compared to the high MWL group. However, all these significant P-values declined after controlling for GA. Diabetes mellitus and pregnancy associated hypertension were not noted in mothers in high MWL group, whereas 38% of mothers in low MWL group suffered from the latter (P=0.05. Maximum postnatal transitional weight loss, assessed in the range of low, moderate and high, is not associated with adverse outcomes independent of gestational age in ELBW infants. Maternal hypertension decreases EPWL in them.

    While the trajectory of self-esteem from adolescence to adulthood varies from person to person, little research has examined how differences in early developmental processes might affect these pathways. This study examined how early motor skill development interacted with preterm birth status to predict self-esteem from adolescence through the early 30s. We addressed this using the oldest known, prospectively followed cohort of extremely low birth weight (self-report, and self-esteem was reported during three follow-up periods (age 12-16, age 22-26, and age 29-36). We found that birth weight status moderated the association between early motor skills and self-esteem. Stable over three decades, the self-esteem of normal birth weight participants was sensitive to early motor skills such that those with poorer motor functioning manifested lower self-esteem, while those with better motor skills manifested higher self-esteem. Conversely, differences in motor skill development did not affect the self-esteem from adolescence to adulthood in individuals born at extremely low birth weight. Early motor skill development may exert differential effects on self-esteem, depending on whether one is born at term or prematurely.

    Extra-uterine growth retardation (EUGR) is associated with an increased risk for cardiometabolic diseases later in life. The aim of the present study was to examine the relationship between early weight change after birth in preterm infants and adiponectin (adn) multimeric complexes. Subjects included 28 preterm infants born between weeks 24 and 33 of gestation. Serum adn multimeric complexes and the anthropometric parameters were measured in preterm infants at birth and at corrected term. Bodyweight (BW) decreased during the first week of life, with birthweight restored at approximately 19 days after birth. Nineteen of the subjects had EUGR at corrected term. Total (T)-adn, high-molecular-weight (H)-adn, and the ratio of H-adn to T-adn (H/T-adn) were significantly elevated at corrected term than at birth. Postmenstrual age, birthweight, birth length and lowest BW after birth were positively correlated with H-adn and H/T-adn. Weight reduction after birth was negatively correlated with H-adn. Age to restore birthweight was negatively correlated with T-adn, H-adn and H/T-adn. Stepwise multiple regression analysis indicated age to restore birthweight as the major predictor of T-adn and H-adn. Early weight changes after birth may alter serum adn level in preterm infants at corrected term. The appropriate nutritional support in the early postnatal period could reduce the prevalence of EUGR and the future risk for cardiometabolic diseases. © 2011 The Authors.

    Full Text Available Abstract Cytomegalovirus (CMV is a DNA virus and a marker of the herpes virus groups. This virus was found only in human and the infection occurs for a long time. The transmission of CMV infection to fetus/neonates is via congenital infections or perinatal infections. Clinical manifestation of symptomatic CMV infection of the fetus has two presentations, early and second early manifestations. Diagnosis of neonatal CMV infection may be done by serologic test based on detection of IgM of CMV infection. The objective of this study is to asses clinical outcome of CMV infection of low birth weight infants delivery with long term sequelae. An observational study was conducted since March 2010 until December 2011 in Advent and Hermina Pasteur Hospital, all subjects were low birth weight infants (LBWI. The inclusion criterias are all LBWI who were delivered in those hospital or were a referred neonates. The exclusion criterias are major congenital defect, which is not related to congenital CMV infection and neonates’ death before one week of life. Every neonate was examine both their physical and peripher blood count, glucose, Ca. Liver function test done for neonates with acute hepatitis and titre IgG and IgM CMV serial, head ultrasound serial and head CT scan/MRI used for babies with intracranial bleeding and hydrocephaly.  During the period of this study there were 50 cases of LBWI, consisted of 41 preterm babies, and 30 small for gestational age babies. Clinical manifestation of acute hepatitis were found in 20% subjects, all of them with the  elevation of liver function test. Microcephaly which occured in the first untill three weeks of life were 8%. Ventricular dilatation were 10% in the first week of life and increased up to 48% after three weeks. Cases with intracranial haemorrhage were found in 6% and 10% with cerebral calcification on head while sensorineural hearing loss were 8%. All of LBWI have 100% serorespon immune IgG. IgM CMV

    The birth weight of Black neonates in the United States is consistently smaller than that of their White counterparts. Epigenetic differences between the races may be involved in such disparities. The goal of these analyses was to model the role of IGF1 methylation in mediating the association between race and birth weight. Data was collected on a cohort of 87 live born infants. IGF1 methylation was measured in DNA isolated from the mononuclear fraction of umbilical cord blood collected after delivery. Quantitative, loci-specific methylation was assessed using the Infinium HumanMethylation27 BeadArray (Illumina Inc., San Diego, CA). Locus specific methylation of the IGF1 CpG site was validated on a subset of the original sample (N = 61) using pyrosequencing. Multiple linear regression was used to examine relationships between IGF1 methylation, race, and birth weight. A formal mediation analysis was then used to estimate the relationship of IGF1 methylation to race and birth weight. Black race was associated with a 7.45% decrease in gestational age-adjusted birth weight (aBW) (P = 0.04) and Black infants had significantly higher IGF1 methylation than non-Black infants (P aBW (P = 0.02). Including IGF1 methylation as a covariate, the effect of Black race on aBW was attenuated. A formal mediation analysis showed that the controlled direct effect of Black race on aBW was -6.26% (95% CI = -14.15, 1.06); the total effect of Black race on IGF1 methylation was -8.12% (95% CI = -16.08, -0.55); and the natural indirect effect of Black race on aBW through IGF1 methylation was -1.86% (95% CI = -5.22, 0.18). The results of the mediation analysis along with the multivariable regression analyses suggest that IGF1 methylation may partially mediate the relationship between Black race and aBW. Such epigenetic differences may be involved in racial disparities observed in perinatal outcomes.

    Full Text Available Abstract Background The proportions of preterm birth (PTB, ie., delivered before 37 gestational weeks and low birth weight (LBW, ie., birth weight less than 2500 g at delivery have been rising in developed countries. We sought to examine the factors contributing to the rise in Japan, with particular focus on the effects of obstetric interventions. Methods We used a database maintained by one large regional hospital in Shizuoka, Japan. We restricted the analysis to mothers who delivered live singleton births from 1997 to 2010 (n = 19,221. We assessed the temporal trends in PTB and LBW, then divided the study period into four intervals and compared the proportions of PTB and LBW. We also compared the newborns’ outcomes between the intervals. Results PTB, in particular medically indicated PTB, increased considerably. The increase was largely explained by changes in caesarean sections. The neonatal outcomes did not worsen, and instead the Apgar scores and proportions requiring neonatal intensive care unit (NICU admission improved. In particular, the risks of NICU admission in the interval from 2007 to 2010 were decreased among all births [odds ratio (OR: 0.84; 95% confidence interval (CI: 0.75, 0.95] and medically indicated births (OR: 0.44; 95% CI: 0.29, 0.68 compared with the interval from 1997 to 2000. Conclusions Despite the increases in PTB as well as LBW, the present study suggests benefits of obstetric interventions. Rather than simple categorization of PTB or LBW, indicators such as perinatal mortality or other outcomes may be more appropriate for evaluation of perinatal health in developed countries.

    2005-01-01

    Within the past 5 years there has been an increase of premature infants surviving in the neonatal intensive care unit as well as an increasing cost for each day the infant is kept there. It is important for the premature infant to acquire the feeding skills necessary for weight gain, which lead to discharge from the hospital, and recent advancements have indicated the effectiveness in using contingent music to teach sucking skills to premature infants. The purpose of the first analysis in this study was to determine the effects of Pacifier Activated Lullaby (PAL) trials on weight gain of premature infants. During a 2-year time period, 62 infants from a sample of 188 met criteria for analysis. A one-way analysis of variance showed no significance in daily weight gain for the number of PAL trials completed. The mean weight gains for infants with 1 PAL trial = 13.85 grams, 2 trials = 26.67, 3 trials = 29.64, and 4 or more = 22.89. The Pearson product-moment correlation between the mean percent of music earned via nonnutritive sucking (NNS) and mean weight gain of all trials approached significance (p = .077, r = 0.18). In a second analysis, weight gained prior to use of PAL, during use of PAL, and post use of PAL was analyzed. Results indicated no significant difference between weight gain 1 day prior to use of PAL, the day of PAL trial, and 1 day post use of PAL. Mean weight gain for those infants who participated in 1 PAL trial was 8.49 grams for 1 day prior to use of PAL, 18.73 the day of PAL trial, and 24.81 for 1 day post use of PAL. Mean weight gain for 3 days prior to using the PAL was 10.78, 11.30 on the day of PAL trial, and 24.78 grams for 3 days post PAL use. The analyses show definite trends of greater weight gain with PAL use; however, individual variability within groups was greater than group differences leading to no significance in statistical analysis. In the third analysis the effect of proximity between premature infants' feeding schedule and PAL

    Full Text Available Abstract Background Premature ovarian failure (POF remains a clinically challenging entity because in vitro fertilisation (IVF with donor oocytes is currently the only treatment known to be effective. Methods A 33 year-old nulligravid patient with a normal karyotype was diagnosed with POF; she had a history of failed fertility treatments and had an elevated serum FSH (42 mIU/ml. Oocytes donated by her dizygotic twin sister were used for IVF. The donor had already completed a successful pregnancy herself and subsequently produced a total of 10 oocytes after a combined FSH/LH superovulation regime. These eggs were fertilised with sperm from the recipient's husband via intracytoplasmic injection and two fresh embryos were transferred to the recipient on day three. Results A healthy twin pregnancy resulted from IVF; two boys were delivered by caesarean section at 39 weeks' gestation. Additionally, four embryos were cryopreserved for the recipient's future use. The sister-donor achieved another natural pregnancy six months after oocyte retrieval, resulting in a healthy singleton delivery. Conclusion POF is believed to affect approximately 1% of reproductive age females, and POF patients with a sister who can be an oocyte donor for IVF are rare. Most such IVF patients will conceive from treatment using oocytes from an anonymous oocyte donor. This is the first report of births following sister-donor oocyte IVF in Ireland. Indeed, while sister-donor IVF has been successfully undertaken by IVF units elsewhere, this is the only known case where oocyte donation involved twin sisters. As with all types of donor gamete therapy, pre-treatment counselling is important in the circumstance of sister oocyte donation.

    Background Low birth weight (LBW) has long been used as an indicator of public health. Low birth weight is not a proxy for any dimension of other maternal or perinatal health outcomes. Low birth weight infants require special care, and have more chronic conditions, learning delays, and attention deficit hyperactivity disorders compared to infants of normal birth weight (NBW). Social competence is viewed as a primary component of healthy function and development and is an important predictor o...

    2012-01-01

    Full Text Available Systemic fungal infections have high morbidity and mortality rates in neonates, especially neonates with an extremely low birth weight (ELBW. Here, we describe a 21-day-old ELBW female infant with an amphotericin B-unresponsive congenital Candida albicans infection that was treated with caspofungin. Blood sterilization was performed during the first episode, but a second episode of candidemia occurred after the discontinuation of caspofungin. Blood sterilization was again performed during the second round of caspofungin treatment, but fungal endocarditis and renal fungal balls still developed during the second episode. Caspofungin can be considered for invasive candidiasis in premature infants, especially in life-threatening situations. As for the focal lesions, more aggressive treatments other than just parenteral antibiotics should be considered. The literature regarding caspofungin therapy for neonatal candidiasis is also reviewed.

  11. Intergenerational predictors of birth weight in the Philippines: correlations with mother's and father's birth weight and test of maternal constraint.

    Directory of Open Access Journals (Sweden)

    Christopher W Kuzawa

    Full Text Available BACKGROUND: Birth weight (BW predicts many health outcomes, but the relative contributions of genes and environmental factors to BW remain uncertain. Some studies report stronger mother-offspring than father-offspring BW correlations, with attenuated father-offspring BW correlations when the mother is stunted. These findings have been interpreted as evidence that maternal genetic or environmental factors play an important role in determining birth size, with small maternal size constraining paternal genetic contributions to offspring BW. Here we evaluate mother-offspring and father-offspring birth weight (BW associations and evaluate whether maternal stunting constrains genetic contributions to offspring birth size. METHODS/PRINCIPAL FINDINGS: Data include BW of offspring (n = 1,101 born to female members (n = 382 and spouses of male members (n = 275 of a birth cohort (born 1983-84 in Metropolitan Cebu, Philippines. Regression was used to relate parental and offspring BW adjusting for confounders. Resampling testing was used to evaluate whether false paternity could explain any evidence for excess matrilineal inheritance. In a pooled model adjusting for maternal height and confounders, parental BW was a borderline-significantly stronger predictor of offspring BW in mothers compared to fathers (sex of parent interaction p = 0.068. In separate multivariate models, each kg in mother's and father's BW predicted a 271±53 g (p25% and likely 50% would be needed to explain these differences. There was no interaction between maternal stature and maternal BW (interaction p = 0.520 or paternal BW (p = 0.545. CONCLUSIONS/SIGNIFICANCE: Each kg change in mother's BW predicted twice the change in offspring BW as predicted by a change in father's BW, consistent with an intergenerational maternal effect on offspring BW. Evidence for excess matrilineal BW heritability at all levels of maternal stature points to indirect genetic

    2009-01-01

    Children with very low birth weight (VLBW, mathematics disabilities or deficiencies (MD) and higher rates of mathematics learning disabilities (MLD) than normal birth weight term-born children (NBW, >2500 g and >36 weeks GA). MD are found even in children without global disorders in cognition or neurosensory status and when IQ is controlled, and they are associated with other learning problems and weaknesses in perceptual motor abilities and executive function. Factors related to poorer mathematics outcomes include lower birth weight and GA, neonatal complications, and possible abnormalities in brain structure. While little is known about the nature of MD in these children, studies of MLD in other neurodevelopmental disorders and in children with learning disabilities provide useful models for further investigation. Further investigation of the neuropsychological and neuropathological correlates of distinct types of mathematics difficulties is also needed. Studies along these lines will yield information about the unique features of MD in children with VLBW/VPTB and about the nature and origins of poor mathematics achievement more generally.

    We analysed at what age parents start complementary food in very low birth weight infants, determined risk factors for early introduction of complementary food (post-term age) and analysed whether the age at introduction of complementary food influences height or weight at 2 years of age. Parents of premature infants born in 2009-2011 answered questionnaires regarding introduction of complementary food in the first year of life (N=2262) and were followed up at a post-term age of 2 years (N=981). Length and weight were compared with full-term infants from the KiGGs study. Logistic and linear regression analyses were conducted to study predictors for early introduction of complementary food and the influence of age at introduction of complementary food on later height and weight. Average age at introduction of complementary food was 3.5 months post-term age. The lower the gestational age at birth, the earlier (post-term age) vegetables and meat were introduced. Age at introduction of complementary food was influenced by intrauterine growth restriction, gestational age at birth, maternal education and a developmental delay perceived by the parents. Length and weight at a post-term age of 2 years was not negatively influenced by early introduction of complementary food. VLBW infants are introduced to complementary food on average before a post-term age of 4 months. There was no negative effect of early introduction of complementary food on height and weight at 2 years of age.

    Full Text Available Poor maternal nutrition is a major contributor to the high incidence of low birth weight deliveries in developing countries. This study aimed to assess the impact of second trimester maternal dietary intake on gestational weight gain and neonatal birth weight. A longitudinal study was conducted in a tertiary care hospital in Sri Lanka. Participants were 141 pregnant women at 18–24 weeks gestation who were followed up until delivery. Maternal dietary intake was assessed using a validated Food Frequency Questionnaire at 21.1 ± 1.8 gestational weeks. Gestational weight gain was examined at the end of 28 weeks gestation and at the end of pregnancy. Energy and nutrient intakes were calculated using NutriSurvey 2007 (EBISpro, Willstaett, Germany nutrient analysis software, modified for Sri Lankan foods. The mean total gestational weight gain of women with low carbohydrate intake (229–429 g/day was 2.2 kg less than that of women with moderate carbohydrate intake (430–629 g/day (95% confidence interval (CI 0.428–4.083 kg; p = 0.016. Similarly, babies of women with low carbohydrate intake were 312 g lighter compared with those of women with a moderate carbohydrate intake (95% CI 91–534 g; p = 0.006. Our results suggest that second trimester maternal carbohydrate intake has significant impacts on total gestational weight gain and neonatal birth weight.

    To investigate the effects of state minimum wage laws on low birth weight and infant mortality in the United States. We estimated the effects of state-level minimum wage laws using a difference-in-differences approach on rates of low birth weight (minimum wage above the federal level was associated with a 1% to 2% decrease in low birth weight births and a 4% decrease in postneonatal mortality. If all states in 2014 had increased their minimum wages by 1 dollar, there would likely have been 2790 fewer low birth weight births and 518 fewer postneonatal deaths for the year.

    Full Text Available The FTO gene, located on chromosome 16q12.2, and the MAF gene, located on chromosome 16q22-23, were identified as genes harboring common variants with an impact on obesity predisposition. We studied the association of common variants with birth weight, gain of body weight, body mass index (BMI, Ponderal index and relevant neonatal outcomes in a large German cohort of infants with a birth weight below 1500 grams.The single nucleotide polymorphisms rs9939609 (FTO gene and rs1424233 (MAF gene were genotyped using allelic discrimination assays in a prospective multicenter cohort study conducted in 15 neonatal intensive care units in Germany from September 2003 until January 2008. DNA samples were extracted from buccal swabs according to standard protocols.1946 infants were successfully genotyped at FTO and 2149 infants at MAF. Allele frequencies were not significantly different from other European cohorts. The polymorphisms were in Hardy-Weinberg equilibrium. The polymorphisms did not show associations with birth weight, BMI and Ponderal Index at discharge, and weight gain, neither testing for a dominant, additive nor for a recessive model.Since an association of the polymorphisms with weight gain has been demonstrated in multiple populations, the lack of association in a population of preterm infants with regular tube feeding after birth and highly controlled feeding volumes provides evidence for the hypothesis that these polymorphisms affect food intake behavior and hunger rather than metabolism and energy consumption.

    Full Text Available Objective: to evaluate the relationship between body composition of preschool children suffering from excess weight and birth weight (BW. Methods: probabilistic sample, by conglomerates, with 17 daycare centers (of a total of 59 composing a final sample of 479 children. We used Z-score of Body Mass Index (zBMI ≥ +1 and ≥ +2, respectively, to identify preschool children with risk of overweight and excess weight (overweight or obesity. The arm muscle area (AMA and the arm fat area (AFA were estimated from measurements of arm circumference, triceps skin fold thickness. Results: the prevalence of risk of overweight was 22.9% (n=110 and excess weight was 9.3% (n=44. The risk of overweight and excess weight in children did not show correlation between BW and AFA, but it did with adjusted arm muscle area (AMAa (rp= 0.21; p= 0.0107. The analysis of the group with excess weight alone also showed a positive correlation between BW and AMAa (rp= 0.42; p= 0.0047. Conclusion: among overweight children, lower BW is associated with a lower arm muscle area in early preschool age, regardless of the fat arm area presented by them.

    2017-04-01

    Full Text Available Background/Aims: Fetal metabolism may be changed by the exposure to maternal factors, and the route to obesity may already set in utero. Cord blood metabolites might predict growth patterns and later obesity. We aimed to characterize associations of cord blood with birth weight, postnatal weight gain, and BMI in adolescence. Methods: Over 700 cord blood samples were collected from infants participating in the German birth cohort study LISAplus. Glycerophospholipid fatty acids (GPL-FA, polar lipids, non-esterified fatty acids (NEFA, and amino acids were analyzed with a targeted, liquid chromatography-tandem mass spectrometry based metabolomics platform. Cord blood metabolites were related to growth factors by linear regression models adjusted for confounding variables. Results: Cord blood metabolites were highly associated with birth weight. Lysophosphatidylcholines C16:1, C18:1, C20:3, C18:2, C20:4, C14:0, C16:0, C18:3, GPL-FA C20:3n-9, and GPL-FA C22:5n-6 were positively related to birth weight, while higher cord blood concentrations of NEFA C22:6, NEFA C20:5, GPL-FA C18:3n-3, and PCe C38:0 were associated with lower birth weight. Postnatal weight gain and BMI z-scores in adolescents were not significantly associated with cord blood metabolites after adjustment for multiple testing. Conclusion: Potential long-term programming effects of the intrauterine environment and metabolism on later health cannot be predicted with profiling of the cord blood metabolome.

    The goals of our study were (1) to estimate the trends in maternal weight gain patterns and (2) to estimate the influence of variation in maternal weight and rate of weight gain over different time periods in gestation on variation in birth weight in African-American and non-African-American gravidas. Data from a prospective cohort study in which pregnant women were monitored at multiple time points during pregnancy were analysed. Maternal weight was measured at three times during pregnancy: preconception (W(0)); 16-20 weeks gestation (W(1)); 30-36 weeks gestation (W(2)), in a cohort of 435 women with full-term singleton pregnancies. The relationship between gestational age-adjusted birth weight (aBW) and measures of maternal weight and rate of weight gain across pregnancy was estimated using a multivariable longitudinal regression analysis stratified on African-American race. The aBW was significantly associated with maternal weight measured at any visit in both strata. For African-American women, variation in aBW was significantly associated with variation in the rate of maternal weight gain in the first half of pregnancy (W(01)) but not the rate of maternal weight gain in the second half of pregnancy (W(12)); while for non-African-American women, variation in aBW was significantly associated with W(12) but not W(01). Factors influencing the relationship between aBW and maternal weight gain patterns depend on the context of the pregnancy defined by race. Clinical decisions and recommendations about maternal weight and weight gain during pregnancy may need to account for such heterogeneity.

    Full Text Available BACKGROUND: Low Birth Weight is a multi-factorial problem of health and social concern Worldwide. India accounts for 40 percent of Low birth weight (LBW babies of the developing World and more than half of those in Asia. Despite the multitude of services rendered to improve maternal health care, LBW remains a public health problem in India. Objective: To determine bio-social predictors of low birth weight amongst the institutional births in North Karnataka, India. METHODS: A prospective hospital based study was conducted in Belgaum district of north Karnataka during July 2012-March 2013. A total of 426 pregnant women registered within 20 weeks of gestation during July–September 2013; eventually delivered in the same hospital were included in the study. Birth weight was measured by a digital weighing scale of 100 gram accuracy. Data were collected through individual interviews using pretested questionnaire. Data were analyzed by SPSS (16.0 Version. Descriptive statistics and multivariate regression were applied. P value < 0.05 considered significant. RESULTS: Mean age of subjects was 23.2254±3.09 years. About 96.7% were literates. Mean age at first pregnancy was 21.37±2.70 years. Low birth weight was observed amongst 22.5% new born (Mean weight: 2089.58±268.31gm. Almost 10.0% were preterm births. Paternal education and occupation, socio-economic status, religion, maternal blood group and gestation age at delivery were found to be the independent and significant bio-social factors predicting the low birth weight. About 68.0% variations in the birth weight were explained by these predictors. CONCLUSIONS: Low paternal education and occupation (farmers/laborers, low socio-economic status, maternal blood group (A is protective and prematurity were found to be independent bio-social predicators of LBW. Programme targeting paternal education may be useful and study of biological plausibility associated with the maternal blood group is recommended.

    Full Text Available Esophageal atresia is complex congenital anomaly of respiratory tract occuring often associated with anomalies of other systems and chromosomal abnormalities. This congenital anomaly is a surgical emergency. The management mode of Esophageal atresia/ Tracheoesophageal Fistula in the premature, low birth weight neonate remains controversial. Traditionally, treatment has been based on a staged approach. The primary repair of Esophageal atresia and fistula closure is achievable in Low Birth Weight infants and offer a good treatment in the absence of additional severe malformations. Treatment of these neonates should not be limited to tertiary pediatric surgical centers, contrarily it is also achievable in secondary heath care centers. Near cooperation with neonatal intensivist and the pediatric surgeon is essential for good survival. [Cukurova Med J 2015; 40(2.000: 340-344

    Full Text Available In­tro­duc­ti­on: Patent Ductus Arteriosus (PDA, a cardiac pathology commonly seen in preterm infants, has negative effects on mortality and morbidity. Persistent patency of PDA is positively correlated with respiratory distress syndrome (RDS, prolonged respiratory support, pulmonary hemorrhage, broncopulmonary dysplasia (BPD, necrotizing enterocolitis (NEC, intraventricular hemorrhage, renal failure, neurodevelopmental impairment (cerebral palsy, retinopathy of prematurity and death. The standard treatment regimen is to close symptomatic PDA and cyclooxygenase inhibitors such as indomethacin, ibuprofen are the first choises. Our aim in this study is to report PDA rate, treatment and complications in premature infants. Materials and Methods: This study retrospectively enrolled 103 infants born <33 gestational weeks, without any major congenital anomaly or congenital heart defects between January 2010-November 2011. Echocardiograms was performed in the first week. PDA related pulmonary hemorrhage, NEC, BPD, ROP and death were demonstrated.Results: Among of 103 infants, 45 were male and 58 were female. Seventy infants were born with cesarian section and 33 were born with normal labor. The mean gestational week was 29.7±2.2, the mean gestational week of infants with PDA was 28.8±2.3. The mean birth weight of infants was 1323±375 grams. The mean Apgar score was 7.25±1.83, the scores of infants with patent ductus arteriosus were significantly low (6.7±1.9. Echocardiography was performed on the mean of 4.8±4.4 days, PDA was determined in 48 of 103 infants (%46. The mean of birth weight of infants with persistant PDA was 1162±351 grams, it was 1465±340 g in the closed group. The rate of pulmonary hemorrhage, NEC, BPD, ROP and death was significantly higher in infants with PDA compared with infants having ductal closure (p<0.05.Conclusion: The early closure of PDA in very low birth weight infants will reduce both mortality and early or late

    Full Text Available Introduction: Infants with low birth weights are provided with hospital nutrition support to enhance their survivability and body weights. However, different hospitals have different nutrition support formulas. Therefore, the effectiveness of these nutrition support formulas should be investigated. Objective: To assess the effect of hospital nutrition support on growth velocity and nutritional status of low birth weight infants at Al-Noor hospital, Saudi Arabia. Methods: A cross-sectional study was conducted between October, 2010 and December, 2012. Three hundred newborns were recruited from Al-Noor Hospital in Makkah city, Saudi Arabia. Infants were selected according to their birth weights and were divided equally into three groups; (i Low Birth Weight (LBW infants (15012500 g birth weight, (ii Very Low Birth Weight (VLBW infants (1001-1500 g birth weight and (iii Extremely Low Birth Weight (ELBW infants ( 0.05 were observed among groups. Serum calcium, phosphorus and potassium levels at discharge were higher (p < 0.05 than that at birth for ELBW and VLBW groups; while sodium level decreased in ELBW group to be within normal ranges. Albumin level was improved (p < 0.05 in ELBW group. Conclusion: Health care management for low birth weight infants in Al-Noor Hospital was not sufficient to achieve normal growth rate for low birth weight infants, while biochemical indicators were remarkably improved in all groups.

    A decline in serum progesterone or antagonism of progesterone receptor function results in preterm labor and birth. Whether characteristics of premature remodeling of the cervix after antiprogestins or ovariectomy are similar to that at term was the focus of the present study. Groups of pregnant rats were treated with vehicle, a progesterone receptor antagonist (onapristone or mifepristone), or ovariectomized on day 17 postbreeding. As expected, controls given vehicle delivered at term while rats delivered preterm after progesterone receptor antagonist treatment or ovariectomy. Similar to the cervix before term, the preterm cervix of progesterone receptor antagonist-treated rats was characterized by reduced cell nuclei density, decreased collagen content and structure, as well as a greater presence of macrophages per unit area. Thus, loss of nuclear progesterone receptor-mediated actions promoted structural remodeling of the cervix, increased census of resident macrophages, and preterm birth much like that found in the cervix at term. In contrast to the progesterone receptor antagonist-induced advance in characteristics associated with remodeling, ovariectomy-induced loss of systemic progesterone did not affect hypertrophy, extracellular collagen, or macrophage numbers in the cervix. Thus, the structure and macrophage census in the cervix appear sufficient for premature ripening and birth to occur well before term. With progesterone receptors predominantly localized on cells other than macrophages, the findings suggest that interactions between cells may facilitate the loss of progesterone receptor-mediated actions as part of a final common mechanism that remodels the cervix in certain etiologies of preterm and with parturition at term.

Aim: To report the spectrum of ROP and associated risk factors in babies weighing > 1250 g at birth in a developing country. Setting and Design: Institutional, retrospective, non-randomized, observational clinical case series. Materials and Methods : Retrospective analysis (10 years of 275 eyes (138 babies with ROP. Statistical Analysis: Qualitative data with the Chi-square test. Quantitative data using the unpaired t test or the ANOVA and further tested using multivariate logistic regression. Results: The mean birth weight was 1533.9 g (range 1251 to 2750 g and the mean period of gestation was 30.9 weeks (range 26 to 35. One hundred and twenty-four of 275 eyes (45.1% had threshold or worse ROP. Risk factors for threshold or worse disease were, ′outborn babies′ ( P < 0.001, respiratory distress syndrome ( P = 0.007 and exchange transfusion ( P = 0.003. The sensitivity of the American and British screening guidelines to pick up threshold or worse ROP in our study group was 82.4% and 77.4% respectively. Conclusions : Severe ROP is often encountered in babies weighing greater than 1250 g at birth in developing countries. Western screening guidelines may require modifications before application in developing countries.

    Full Text Available In recent decades there has been substantial progress in the technology of premature infants nursing, especially with extremely low birth weight. Adequate feeding is one of the fundamental factors of premature babies nursing. To ensure a premature baby with all necessary components for power saving in breast milk intake, breast milk fortifiers — specifically developed additives that adjust the composition of food for premature babies, are used for more than 20 years (for premature babies receiving breast milk. On the one hand, to preserve all benefits of breastfeeding, on the other — to prevent the deficit development of necessary elements for adequate growth and development of nutrients.

    Adults born preterm at very low birth weight (VLBW; blood pressure than those born at term. It is not known whether all VLBW adults are at risk or whether higher blood pressure could be attributed to some of the specific conditions underlying or accompanying preterm birth. To identify possible risk or protective factors, we combined individual-level data from 9 cohorts that measured blood pressure in young adults born at VLBW or with a more stringent birth weight criterion. In the absence of major heterogeneity, we performed linear regression analysis in our pooled sample of 1571 adults born at VLBW and 777 controls. Adults born at VLBW had 3.4 mm Hg (95% confidence interval, 2.2-4.6) higher systolic and 2.1 mm Hg (95% confidence interval, 1.3-3.0) higher diastolic pressure, with adjustment for age, sex, and cohort. The difference in systolic pressure was present in men (1.8 mm Hg; 95% confidence interval, 0.1-3.5) but was stronger in women (4.7 mm Hg; 95% confidence interval, 3.2-6.3). Among the VLBW group, blood pressure was unrelated to gestational age, maternal smoking, multiple pregnancy, retinopathy of prematurity, or bronchopulmonary dysplasia. Blood pressure was higher than that of controls among VLBW adults unexposed to maternal preeclampsia. Among those exposed, it was even higher, especially if born appropriate for gestational age. In conclusion, although female sex and maternal preeclampsia are additional risk factors, the risk of higher blood pressure is not limited to any etiologic subgroup of VLBW adults, arguing for vigilance in early detection of high blood pressure in all these individuals. © 2016 American Heart Association, Inc.

    Introduction Preterm and low birth weight tend to occur as a direct result of prenatal risky behaviors, diseases, as well as fetal exposure to harmful social and environmental factors. The present study aimed to investigate the relationship between job style and preterm low birth weight. Methods The present case-control study was conducted in the Kamali hospital, Teheran, Iran in 2014. Participants included 156 mothers having a gestational age of less than 37 weeks and infants weighing less than 2500 gm. Additionally, the control group consisted of 433 mothers with a gestational age of over 37 weeks and having infants weighing between 2500–4000 gm. The data were collected using the Mother’s Lifestyle Scale (MLS) during pregnancy based on recognized social determinants of health and those developed by the researchers. The domain of the mother’s job style was assessed using a questionnaire consisting of 18 items on topics such as working conditions, job satisfaction, and perceived employer empathy. Higher overall scores in this instrument indicate the mother’s poorer job style. The data were analyzed using SPSS version 16 and Lisrel version 8.8 through a statistical path analysis. Results The model fit indices indicated that there was found to be high favorability, demonstrated that the model fit and that there were rational relationships (CFI=1, RMSEA=0.00), and showed that on the direct path that the mother’s job style had the most adverse effect (B=−0.3) with weight gain during pregnancy showing the most positive effect (B=0.16) on PLBW. The mother’s level of education was found to be the only variable that affected PLBW negatively in both the direct and indirect paths through the mother’s job style and household income (B=−0.17). Conclusion According the path analysis model, job style has a direct influence on preterm low birth weight. Thus, special consideration should be placed on aspects surrounding a mother’s job situation in order to

    The aim of this study was to evaluate physical growth of very low birth weight (VLBW) preterm babies at a mean age of three years and to investigate the factors which affected growth. The factors including maternal problems, prenatal problems, early neonatal problems, nutrition, familial socioeconomical status and presence of chronic disease which affected catch-up growth in terms of height and weight in VLBW infants followed up in the neonatal intensive care unit (NICU) of our hospital were examined. The target height formula was used in assessment of growht in height and the contribution of genetic properties was investigated. The points of the subjects on the growth curve were plotted according to the Percentile Curve of the Turkish Children prepared by Neyzi et al. The states of the subjects with and without intrauterine growth retardation (were compared. The study was intitiated after obtaining approval from the ethics committeee of our hospital (100/25.10.2005). One hundred and seventeen preterm babies (57 females and 60 males) with a mean adjusted age of 35.8±2.39 80 of whom were appropriate for gestational age (AGA), 28 of whom were symmetrical (small gestational age) SGA and 9 of whom were asymmetrical SGA were included in the study. The mean gestational age (GA) was found to be 31±2.16 weeks and the mean birth weight (BW) was found to be 1271±226 g. The mean current height was found to be 92.06±4.90 cm. The mean weight was found to be 12.98±1.94 kg. The mean target height was calculated to be 163.66±8.1 cm (157.20 cm for the girls and 170.20 cm for the boys). It was found that 15 preterm babies (12.8%) could not achieve the target height (girls: 6%, boys: 6.8%). The risk factors related with failure to achieve target height were found to include ventilator treatment, presence of chronic disease, advanced stage intracranial bleeding (ICB), posthemorrhagic hydrocephalus, absence of breastfeeding, failure to sit at the table with the family and

    To study the associations of maternal tobacco use (smoking or use of snuff) and risk of extremely preterm birth, and if tobacco cessation before antenatal booking influences this risk. To study the association between tobacco use and spontaneous or medically indicated onset of delivery. Population-based cohort study. Sweden. All live singleton births, registered in the Swedish Medical Birth Register, 1999-2012. Odds ratios (OR) with 95% confidence intervals (CI) were calculated using multiple logistic regression analysis. Extremely preterm birth (<28 weeks of gestation), very preterm birth (28-31 weeks), moderately preterm birth (32-36 weeks). Maternal snuff use (OR 1.58; 95% CI: 1.14-2.21) and smoking (OR 1.61; 95% CI: 1.39-1.87 and OR 1.91; 95% CI: 1.53-2.39 for moderate and heavy smoking, respectively) were associated with an increased risk of extremely preterm birth. When cessation of tobacco use was obtained there was no increased risk of preterm birth. Snuff use was associated with a twofold risk increase of medically indicated extremely preterm birth, whereas smoking was associated with increased risks of both medically indicated and spontaneous extremely preterm birth. Snuff use and smoking in pregnancy were associated with increased risks of extremely preterm birth. Women who stopped using tobacco before the antenatal booking had no increased risk. These findings indicate that nicotine, the common substance in cigarettes and snuff, is involved in the mechanisms behind preterm birth. The use of nicotine should be minimized in pregnancy. Tobacco use increases risk of extremely preterm birth. Cessation is preventive. Avoid nicotine in pregnancy. © 2016 Royal College of Obstetricians and Gynaecologists.

    We examined if very low-birth-weight (VLBW) infants of multiple gestation pregnancies experience more complications and take longer to achieve clinical milestones compared with similar singletons. We performed a retrospective analysis of all infants less than 1500 g at birth in a large neonatal database. Singletons were compared with twins and higher-order multiples for demographic, morbidities, and process milestones including feeding, respiratory, thermoregulation, and length of stay. Multivariable regression analyses were performed to control for potential confounding variables. A total of 5507 infants were included: 3792 singletons, 1391 twins, and 324 higher-order multiples. There were no differences in Apgar scores, small for gestational age status, and incidence of necrotizing enterocolitis, severe retinopathy of prematurity, severe intraventricular hemorrhage, sepsis, bronchopulmonary dysplasia, or the need for surgery. Multiples had higher rates of apnea and patent ductus arteriosus than singletons. VLBW multiples achieved milestones at similar rates in most areas compared with singletons except for the achievement of full oral feedings. Length of stay, after controlling for confounding variables, did not differ between the groups. Compared with singletons, VLBW multiples had similar morbidity and achieved most feeding and thermoregulation milestones at similar rates.

    Full Text Available Abstract Background Gestational age and birth weight are the principal determinants of newborn’s health status. Chile, a middle income country traditionally has public policies that promote maternal and child health. The availability of an exhaustive database of live births has allows us to monitor over time indicators of newborns health. Methods This descriptive epidemiological study included all live births in Chile, both singleton and multiple, from 1991 through 2008. Trends in gestational age affected the rate of prevalence (% of preterm births ( Results Data from an exhaustive register of live births showed that the number of term and postterm births decreased and the number of multiple births increased significantly. Birth weights exceeding 4000 g did not vary. Total preterm births rose from 5.0% to 6.6%, with increases of 28% for the singletons and 31% for multiple births (p for trend  The overall rate of low birth weight infants ( Conclusions The gestational age and birth weight of live born child have significantly changed over the past two decades in Chile. Monitoring only overall rates of preterm births and low-birth-weight could provide restricted information of this important problem to public health. Monitoring them by specific categories provides a solid basis for planning interventions to reduce adverse perinatal outcomes. This epidemiological information also showed the need to assess several factors that could contribute to explain these trends, as the demographics changes, medical interventions and the increasing probability of survival of extremely and very preterm child.

    This research determines whether the observed decline in infant mortality with socioeconomic level, operationalized as maternal education (dichotomized as college or more, versus high school or less), is due to its "indirect" effect (operating through birth weight) and/or to its "direct" effect (independent of birth weight). The data used are the 2001 U.S. national African American, Mexican American, and European American birth cohorts by sex. The analysis explores the birth outcomes of infants undergoing normal and compromised fetal development separately by using covariate density defined mixture of logistic regressions (CDDmlr). Among normal births, mean birth weight increases significantly (by 27-108 g) with higher maternal education. Mortality declines significantly (by a factor of 0.40-0.96) through the direct effect of education. The indirect effect of education among normal births is small but significant in three cohorts. Furthermore, the indirect effect of maternal education tends to increase mortality despite improved birth weight. Among compromised births, education has small and inconsistent effects on birth weight and infant mortality. Overall, our results are consistent with the view that the decrease in infant death by socioeconomic level is not mediated by improved birth weight. Interventions targeting birth weight may not result in lower infant mortality.

    Birth weight is an important determinant for child development and survival. Birth weight has been reported to be increasing with the passing years. There is no such accurate documentation from the state of Manipur. This cross sectional study has been attempted to see the birth weight pattern in the largest referral hospital in Manipur. Birth weights of four reference years in the last 15 years have been extracted from the records and analysed. There were 19478 singleton deliveries in the four reference years. The mean birth weight showed a gradual increase in these years. There was a gain of 88.9 g in 2000 since 1986 in term deliveries. There were significant differences in the mean birth weights among the four years, even after stratifying for gestation. However, there was no significant decrease in the percentage of low birth weight babies in these years. Low birth weight showed significant association with parity, age of the mother, booking status, haemoglobin level, and literacy of the mother. Since there was no significant decrease in low birth weight babies in spite of increasing birth weight, there is a need for continued and committed effort to realize the goals of RCH.

    Full Text Available 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. 77 preterm infants (32 ELBW; 45 VLBW and 120 full term (FT infants and their mothers were recruited. At 3 months of corrected age, 5 minutes 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 behaviours 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 help to plan

    Low birth weight is associated with adverse health outcomes. If birth weight records are not available, studies may use recalled birth weight. It is unclear whether this is reliable. We performed a systematic review and meta-analysis of studies comparing recalled with recorded birth weights. We followed the Meta-Analyses of Observational Studies in Epidemiology (MOOSE) statement and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched MEDLINE, EMBASE and Cumulative Index to Nursing and Allied Health Literature (CINAHL) to May 2015. We included studies that reported recalled birth weight and recorded birth weight. We excluded studies investigating a clinical population. Two reviewers independently reviewed citations, extracted data, assessed risk of bias. Data were pooled in a random effects meta-analysis for correlation and mean difference. In total, 40 studies were eligible for qualitative synthesis (n=78,997 births from 78,196 parents). Agreement between recalled and recorded birth weight was high: pooled estimate of correlation in 23 samples from 19 studies (n=7406) was 0.90 [95% confidence interval (CI) 0.87-0.93]. The difference between recalled and recorded birth weight in 29 samples from 26 studies (n=29,293) was small [range -86-129 g; random effects estimate 1.4 g (95% CI -4.0-6.9 g)]. Studies were heterogeneous, with no evidence for an effect of time since birth, person reporting, recall bias, or birth order. In post-hoc subgroup analysis, recall was higher than recorded birth weight by 80 g (95% CI 57-103 g) in low and middle income countries. In conclusion, there is high agreement between recalled and recorded birth weight. If birth weight is recalled, it is suitable for use in epidemiological studies, at least in high income countries.

    Full Text Available People born preterm at very low birth weight (VLBW, ≤1500g have higher rates of risk factors for adult-onset diseases, including cardiovascular diseases and type 2 diabetes. These risks may be mediated through epigenetic modification of genes that are critical to normal growth and development.We measured the methylation level of an imprinted insulin-like-growth-factor 2 (IGF2 locus (IGF2/H19 in young adults born preterm at VLBW and in their peers born at term. We studied 158 VLBW and 161 control subjects aged 18 to 27 years from the Helsinki Study of Very Low Birth Weight Adults. Methylation fraction at two IGF2 differentially methylated regions (DMRs - IGF2 antisense transcript (IGF2AS, also known as IGF2 DMR0 and last exon of IGF2 (IGF2_05, also known as IGF2 DMR2 - were measured with Sequenom Epityper. We used linear regression and adjustment for covariates to compare methylation fractions at these DMRs between VLBW and control subjects.At one IGF2AS CpG site, methylation was significantly lower in VLBW than in control subjects, mean difference -0.017 (95% CI; -0.028, -0.005, P = 0.004. Methylation at IGF2_05 was not different between the groups.Methylation of IGF2AS is altered 20 years after preterm birth at VLBW. Altered methylation may be a mechanism of later increased disease risk but more data are needed to indicate causality.

    Full Text Available Background: There have been several publications from different countries on the relationship between the placental weight and birth weight of the neonate. However, such reports from Nigeria are lacking in literature. The objective of this study was to determine the relationship between the placental weight and birth weight of the neonate at term pregnancy in a Nigerian hospital. Materials and Methods: It was a cross-sectional study conducted at Usmanu Danfodiyo University Teaching Hospital Sokoto between 1 st October 2008 and 31 st March 2009. Data gestational age at delivery (in weeks, parity, mode of delivery, fetal birth weight, placental weight, fetal gender, presence or absence of maternal medical diseases were obtained from 1009 singleton term deliveries who met the inclusion criteria for the study. The data was processed using EPI-INFO version 2005 and statistical analysis performed using one-way analysis of variance. A probability of 0.05 was set for statistical significance. Results: The placental birth weight ranged from 300 to 890 g with a mean of 590±82 g while the birth weight of the neonate ranged from 2030 to 5020 g with an average of 3275±469 g. The mean gestational age at delivery was 38.8±1.1 weeks while the mean placental birth weight ratio was 18.2±2.4 Increase in birth weight of the neonate was associated with corresponding increase in placental weight. However, as the gestational age at term advances the proportion of increase in the former was greater than that of the latter. Conclusions: There is a positive correlation between placental weight and birth weight of the neonate. However, the ratio of the placental and neonatal birth weights at term decreases with advancing gestational age. Thus, prolongation of pregnancy at term may adversely affect the fetus.

    Gestation lengths and birth weights were measured in 162 pregnancies in alpacas (Lama pacos) farmed in the high country of the South Island of New Zealand. A comparison of pregnancies from spring (mid-October to mid-December) and autumn (mid-February to late April) matings showed that gestation lengths were 12.5 days longer in spring (348.9 +/- 1.4 days vs. 336.4 +/- 1.2 days; P gestation length of 0.11 days (P gestation length. After adjustment for gestation length, crias born in autumn weighed 1.0 kg more than those born in spring (8.8 +/- 0.15 kg vs. 7.8 +/- 0.18 kg: P < 0.001). Female crias weighed 0.4 kg less than males at birth (P < 0.05). The results suggest that in this environment it will be difficult to maintain spring-mated females in a 12 month breeding cycle.

    The microbiome, of which the bacterial component alone (microbiota), is estimated to include 10 times more cells than human cells of the body, blooms immediately after birth and evolves in composition and complexity throughout childhood. The gut microbiome has a profound impact on gastrointestinal tract development, maintenance of mucosal surface integrity, and contributes to the nutritional status of the host and thus plays a pivotal role in health and disease. New technologies have enabled the detailed characterization of normal microbial symbionts and dysbiosis-disease associations. This review summarizes the stepwise establishment of the intestinal microbiota, influential environmental factors, and how this may be perturbed in preterm very-low-birth-weight infants. The contribution of the microbiota to provision of energy and nutrients for intestinal development and the nutritional status of the host are reviewed. In addition, the crucial role of the gut microbiota in maintaining mucosal integrity is explored along with how its breakdown can lead to sepsis, necrotizing enterocolitis, and systemic inflammatory response syndrome. Finally, the role of enteral feeding type (human milk, formula, and nutrient fortification) in mediating these processes is discussed, and guidance is provided for nutritional strategies to promote health in these fragile infants.

    Evolving technology and scientific advancement have increased the chances of survival of the extremely premature baby; however, such survival can be associated with some severe long-term morbidities. The research investigates the caregiving and ethical dilemmas faced by neonatal nurses when caring for extremely premature babies (defined as ≤24 weeks' gestation). This article explores the issues arising for neonatal nurses when they considered the philosophical question of 'what if it was me and my baby', or what they believed they would do in the hypothetical situation of going into premature labour and delivering an extremely premature baby. Data were collected via a questionnaire to Australian neonatal nurses and semi-structured interviews with 24 neonatal nurses in New South Wales, Australia. Relevant ethical approvals have been obtained by the researchers. A qualitative approach was used to analyse the data. The theme 'imagined futures' was generated which comprised three sub-themes: 'choice is important', 'not subjecting their own baby to treatment' and 'nurses and outcome predictions'. The results offer an important and unique understanding into the perceptions of nursing staff who care for extremely premature babies and their family, see them go home and witness their evolving outcomes. The results show that previous clinical and personal experiences led the nurses in the study to choose to have the belief that if in a similar situation, they would choose not to have their own baby resuscitated and subjected to the very treatment that they provide to other babies. The theme 'imagined futures' offers an overall understanding of how neonatal nurses imagine what the life of the extremely premature baby and his or her family will be like after discharge from neonatal intensive care. The nurses' past experience has led them to believe that they would not want this life for themselves and their baby, if they were to deliver at 24 weeks' gestation or less. © The

    The new practice guideline on the treatment of extremely premature infants is discussed. The guideline advises to actively treat all children born after 24 0/7 weeks of gestation. Although there is some evidence supporting this view, it is argued that the guideline is incomplete as decisions about the treatment of such newborn infants can only be made after discussion with the parents. The guideline should also have taken into account the ethical and legal aspects of the issue. It is therefore concluded that the guideline itself is immature and premature.

    Very premature infants born in the last century following the early days of post-neonatal intensive care have demonstrated an array of physical, emotional, and mental health problems as they approach their third and fourth decades. These outcomes have been well documented by several international investigators. However, there is a paucity of information on the personal perspectives of these individuals with regard to their own quality of life, their hopes and their fears. This article will focus on the objective information from the published literature and how it differs from the personal perspectives of former very premature infants. Crown Copyright © 2016.

    To present the conceptual foundations that explain how events occurring during intrauterine life may influence body development, emphasizing the interrelation between low birth weight and risk of obesity throughout life. Google Scholar, Library Scientific Electronic Online (SciELO), EBSCO, Scopus, and PubMed were the databases. "Catch-up growth", "life course health", "disease", "child", "development", "early life", "perinatal programming", "epigenetics", "breastfeeding", "small baby syndrome", "phenotype", "micronutrients", "maternal nutrition", "obesity", and "adolescence" were isolated or associated keywords for locating reviews and epidemiological, intervention and experimental studies published between 1934 and 2014, with complete texts in Portuguese and English. Duplicate articles, editorials and reviews were excluded, as well as approaches of diseases different from obesity. Within 47 selected articles among 538 eligible ones, the thrifty phenotype hypothesis, the epigenetic mechanisms and the development plasticity were identified as fundamental factors to explain the mechanisms involved in health and disease throughout life. They admit the possibility that both cardiometabolic events and obesity originate from intrauterine nutritional deficiency, which, associated with a food supply that is excessive to the metabolic needs of the organism in early life stages, causes endocrine changes. However, there may be phenotypic reprogramming for low birth weight newborns from adequate nutritional supply, thus overcoming a restrictive intrauterine environment. Therefore, catch-up growth may indicate recovery from intrauterine constraint, which is associated with short-term benefits or harms in adulthood. Depending on the nutritional adequacy in the first years of life, developmental plasticity may lead to phenotype reprogramming and reduce the risk of obesity.

  13. The Nexus of Prematurity, Birth Defects, and Intrauterine Growth Restriction: A Role for Plac1-Regulated Pathways

    2013-01-01

    Epidemiological studies have demonstrated an increased prevalence of birth defects and intrauterine growth restriction (IUGR) among infants born prematurely suggesting they share common biological determinants. The identification of key regulatory pathways contributing to this nexus is essential to ongoing efforts to develop effective intervention strategies. Plac1 is a paternally imprinted and X-linked gene that conforms to this paradigm. Examination of a mutant mouse model has confirmed that Plac1 is essential for normal placental development and function. Moreover, it is expressed throughout the developing embryo indicating that it also has broad relevance to embryogenesis. Most notably, its absence in the developing embryo is associated with abnormal brain development and an increased risk of lethal, postnatal hydrocephalus identifying it as a novel, X-linked determinant of brain development. The essential and non-redundant roles of Plac1 in placental and neurological development represent a novel regulatory paradigm for embryonic growth and pregnancy maintenance. Regulatory pathways influenced, in part, by Plac1 are likely to contribute to the observed nexus of IUGR, prematurity, and birth defects. PMID:24600606

    The purpose of this study was to assess the validity of the candidate indicators secretory immunoglobulin A (s-IgA) and sense of coherence (SOC) as predictors of threatened premature birth. This was a panel study conducted on women in their first and latter half of pregnancy during survey period. The survey period was from December 2005 to June 2006 and from December 2007 to June 2008. The women enrolled in the study were asked to complete the survey questionnaire and provide blood samples for the determinations of physiological indicators. The questionnaire consisted of questions related to the stress perception scale (SPS), SOC score as an indicator of modifiers of stress, demographic data, complications in a previous pregnancy, and the course of the current pregnancy. We used s-IgA and high-sensitivity C-reactive protein as a physiological stress indicator and a marker of infection, respectively. Seventy-two eligible subjects were included in the analysis. Twenty-eight (38.9%) subjects had undergone treatment for threatened premature birth, and 44 (61.1%) subjects had not. In the logistic analysis, we set the course of pregnancy as a dependent variable, and age, birth history, smoking habits, a history of miscarriage, premature birth or threatened premature birth, SPS, SOC, and s-IgA in the first half of pregnancy as independent variables. We found that low serum s-IgA levels and low SOC scores in the first half of pregnancy were associated with threatened premature birth. Our results suggest that low serum s-IgA level and SOC score at an early gestational stage are significant indicators for a threatened premature birth.

    There is general agreement about the need for longitudinal studies of very low birth weight infants (VLBWI) to evaluate their postnatal growth and to generate distance and velocity charts that allow neonatologists and pediatricians to detect earlier whether a child is not growing adequately. There are no satisfactory growth charts for VLBWI. We analyzed the weight growth of 262 VLBWIs from birth to 2 years of corrected age. Individual growth profiles were fitted with a 7-constant exponential-logistic function suitable for modelling weight growth pattern. After a postnatal weight loss, all VLBWIs showed a late neonatal peak of velocity between the seventh and 21st weeks; the large majority of them also experienced an early neonatal peak between the second and the sixth weeks. Small-for-gestational-age VLBWIs with major morbidities grew less than reference appropriate-for-gestational-age VLBWIs without major morbidities: at 2 years, the difference in weight was about 860 g. The more severe growth impairment in VLBWIs with major morbidities was almost entirely due to the reduced height of the late neonatal peak of velocity. The mathematical function used in this study is expected to be a useful tool to trace model-based longitudinal distance and velocity charts specific for VLBWIs. Moreover, this function also could be used to evaluate to what extent different pathological conditions or nutritional and medical care protocols affect growth kinetics.

    This paper aims to identify health research priorities that could improve the rate of progress in reducing global neonatal mortality from preterm birth and low birth weight (PB/LBW), as set out in the UN's Millennium Development Goal 4. We applied the Child Health and Nutrition Research Initiative (CHNRI) methodology for setting priorities in health research investments. In the process coordinated by the World Health Organization in 2007-2008, 21 researchers with interest in child, maternal and newborn health suggested 82 research ideas that spanned across the broad spectrum of epidemiological research, health policy and systems research, improvement of existing interventions and development of new interventions. The 82 research questions were then assessed for answerability, effectiveness, deliverability, maximum potential for mortality reduction and the effect on equity using the CHNRI method. The top 10 identified research priorities were dominated by health systems and policy research questions (eg, identification of LBW infants born at home within 24-48 hours of birth for additional care; approaches to improve quality of care of LBW infants in health facilities; identification of barriers to optimal home care practices including care seeking; and approaches to increase the use of antenatal corticosteriods in preterm labor and to improve access to hospital care for LBW infants). These were followed by priorities for improvement of the existing interventions (eg, early initiation of breastfeeding, including feeding mode and techniques for those unable to suckle directly from the breast; improved cord care, such as chlorhexidine application; and alternative methods to Kangaroo Mother Care (KMC) to keep LBW infants warm in community settings). The highest-ranked epidemiological question suggested improving criteria for identifying LBW infants who need to be cared for in a hospital. Among the new interventions, the greatest support was shown for the development of

    To assess the global effect of preterm birth on fetal metabolism and maternal-fetal nutrient transfer, we used a mass spectrometric-based chemical phenotyping approach on cord blood obtained at the time of birth. We sampled umbilical venous, umbilical arterial, and maternal blood from mothers delivering very-low birth weight (VLBW, with a median gestational age and weight of 29 weeks, and 1210 g, respectively) premature or full-term (FT) neonates. In VLBW group, we observed a significant elevation in the levels and maternal-fetal gradients of butyryl-, isovaleryl-, hexanoyl- and octanoyl-carnitines, suggesting enhanced short- and medium chain fatty acid β-oxidation in human preterm feto-placental unit. The significant decrease in glutamine-glutamate in preterm arterial cord blood beside lower levels of amino acid precursors of Krebs cycle suggest increased glutamine utilization in the fast growing tissues of preterm fetus with a deregulation in placental glutamate-glutamine shuttling. Enhanced glutathione utilization is likely to account for the decrease in precursor amino acids (serine, betaine, glutamate and methionine) in arterial cord blood. An increase in both the circulating levels and maternal-fetal gradients of several polyamines in their acetylated form (diacetylspermine and acetylputrescine) suggests an enhanced polyamine metabolic cycling in extreme prematurity. Our metabolomics study allowed the identification of alterations in fetal energy, antioxidant defense, and polyamines and purines flux as a signature of premature birth.

    It is not well understood how grammar emerges in very-low-birth-weight (VLBW) children. The main aim of the present study was to gain information on the emergence of grammar in this group at 2 ; 0. The Finnish version of the Communicative Development Inventory was used to collect data from VLBW children (N = 156) and full-term controls (N = 146). At a group level, the grammatical skills of the VLBW children were significantly weaker than those of the controls. However, when the effect of lexicon size and premature birth on the emergence of grammar was analyzed in detail, few significant differences were found between the groups. The results suggest that even though grammar emerges more slowly for the VLBW children, it emerges in a manner comparable to that of the controls, when the effect of lexicon size is taken into consideration.

    Because previous analyses of prenatal care (PNC) utilization and risk of low birth weight (LBW) may have been influenced by selection bias, we conducted a study using longitudinal data of women with repeat pregnancies. We analyzed Washington State birth certificates of first and second live births (2003-2012). We estimated relative risk (RR) of LBW at second birth associated with Kotelchuck Index PNC level among women stratified by level of PNC in their first birth (n = 67,571). Among women with inadequate PNC prior to their first birth (n = 10,355), women with intermediate or adequate PNC before their second birth (n = 7464) had a reduced risk of LBW (adjusted RR 0.61, 95% CI: 0.48, 0.78) compared to those whose PNC level remained inadequate. Likewise, among women with intermediate or adequate PNC prior to their first birth (n = 57,216), those with inadequate PNC before the second birth (n = 7095) had higher risk of LBW (adjusted RR 1.59, 95% CI: 1.36, 1.85) compared to those who remained at intermediate or adequate PNC. Our findings support the hypothesis that PNC decreases LBW risk at second birth, independent of factors related to the utilization of PNC at first birth.

    Autonomic functioning is altered in infants born at extremely low birth weight (ELBW; 2500 g). HF in the smallest-born ELBW participants was significantly lower than in NBW controls. In both groups, greater birth weight was associated with higher HF. Among ELBW survivors, lower birth weight predicted faster heart rate and higher DBP, but neither heart rate nor DBP appeared to be well-coordinated with baroreflex activity (LF), the principal mechanism for short-term blood pressure regulation.

    Full Text Available Objective. We investigated the possible factors related to the birth weight (BW using the Japanese perinatal database. Methods. The live infants born at 37 to 41 weeks of gestation were enrolled in this study. Cases with diabetic pregnancy, preeclampsia, an anomalous fetus, and a fetus with chromosomal abnormalities were excluded. A multiple regression analysis for confounding factors and an analysis of covariance (ANCOVA for comparing the BW in 2006 and 2010 were used for the statistical analysis. Results. The BW significantly decreased from 2950.8 g in 2006 (n=27,723 to 2937.5 g in 2010 (n=38,008 in the overall population, and this decrease was similar for male and female neonates. All confounding factors, except for the mode of delivery, affected the BW. Primiparity, smoking, and a female gender were related to the decrease in BW, whereas maternal age, maternal height, weight gain during pregnancy, BMI, the use of in vitro fertilization, induction of labor, and gestational duration were related to an increased BW. The ANCOVA showed that no significant change of the BW was seen between 2006 and 2010 (the difference was 2.164 g, P=0.414. Conclusion. The gestational duration is the most important factor affecting the BW in singleton term infants.

    Risk factors for rickets of prematurity have not been re-examined since introduction of high mineral formula, particularly in ELBW infants. We analyzed the incidence and the risk factors of rickets in extremely low birth weight (ELBW) infants. As a retrospective case-control study from 2004 to 2008, risk factors were analyzed in 24 patients with rickets versus 31 patients without. The frequency of rickets in ELBW infants was 24/55 (44%). Infants with rickets were diagnosed at 48.2 ± 16.1 days of age, and improved by 85.3 ± 25.3 days. By radiologic evaluation, 29% were grade 1 rickets, 58% grade 2 and 13% grade 3. In univariate analysis, infants with rickets had significantly higher incidence of patent ductus arteriosus, parenteral nutrition associated cholestasis (PNAC), severe PNAC and moderate/severe bronchopulmonary dysplasia (BPD). In multiple regression analysis, after adjustment for gestation and birth weight, rickets significantly correlated with severe PNAC and with moderate/severe BPD. Serum peak alkaline phosphatase levels were significantly elevated in rickets (P rickets of prematurity remains high and the incidence of severe PNAC and moderate/severe BPD was significantly increased 18 and 3 times, respectively.

  5. Loss of progesterone receptor-mediated actions induce preterm cellular and structural remodeling of the cervix and premature birth.

    Directory of Open Access Journals (Sweden)

    Steven M Yellon

    Full Text Available A decline in serum progesterone or antagonism of progesterone receptor function results in preterm labor and birth. Whether characteristics of premature remodeling of the cervix after antiprogestins or ovariectomy are similar to that at term was the focus of the present study. Groups of pregnant rats were treated with vehicle, a progesterone receptor antagonist (onapristone or mifepristone, or ovariectomized on day 17 postbreeding. As expected, controls given vehicle delivered at term while rats delivered preterm after progesterone receptor antagonist treatment or ovariectomy. Similar to the cervix before term, the preterm cervix of progesterone receptor antagonist-treated rats was characterized by reduced cell nuclei density, decreased collagen content and structure, as well as a greater presence of macrophages per unit area. Thus, loss of nuclear progesterone receptor-mediated actions promoted structural remodeling of the cervix, increased census of resident macrophages, and preterm birth much like that found in the cervix at term. In contrast to the progesterone receptor antagonist-induced advance in characteristics associated with remodeling, ovariectomy-induced loss of systemic progesterone did not affect hypertrophy, extracellular collagen, or macrophage numbers in the cervix. Thus, the structure and macrophage census in the cervix appear sufficient for premature ripening and birth to occur well before term. With progesterone receptors predominantly localized on cells other than macrophages, the findings suggest that interactions between cells may facilitate the loss of progesterone receptor-mediated actions as part of a final common mechanism that remodels the cervix in certain etiologies of preterm and with parturition at term.

  6. Magnitude and Correlates of Low Birth Weight at Term in Rural Wardha, Central India

    2016-05-01

    Full Text Available Introduction: Birth weight is one of the most important determinant of the neonatal and infant survival. The goal of reducing low birth weight incidence by at least one third between 2000 and 2010 was one of the major goals in ‘A World Fit for Children’. The prevention of low birth weight is a public health priority, particularly in developing countries with high magnitude. Knowledge regarding magnitude and correlates help prevent the condition. Hence, the present study was carried out to study the magnitude and the correlates of low birth weight. Methodology: Two hundred and six newborn babies were recruited on a birth cohort from two Primary Health Centres (PHC of Wardha district to study growth in first year of life. Here, we present the baseline analysis of 172 children who were born full term to study the correlates of low birth weight babies born full term. The children were recruited within first week of their birth. Data was collected on socio-demographic profile, birth history, and maternal characteristics. Proportion of low birth weight was expressed in percentage along with 95% confidence interval. Univariate and multivariate logistic regression was used to study the correlates. Findings are expressed in odds ratios with their 95% confidence intervals. Results: The magnitude of low birth weight at term was found to be 33.1% (95% CI: 26.4%-40.4%. On univariate analysis, significant correlates of low birth weight were consumption of less than 50 iron-folic acid tables and being born to than mother. On multivariate analysis, the significant correlates were female sex of child (OR=2.856, being born to thin mother (OR=5.320, consumption of less than 50 tablets (OR=4.648, and complications of pregnancy (OR=2.917. Conclusions: The magnitude of low birth weight is very high and modifiable correlates of low birth weight are nutritional status of mother, lower consumption of IFA tablets and complications of pregnancy.

    In developing countries, where about 75% of births occur at home or in the community, logistic problems prevent the weighing of every newborn child. This study compares various anthropometric surrogates for identification of low birth weight neonates. A longitudinal community based study was done in an urban resettlement colony and 283 singleton neonates within 7 days of birth were examined for the anthropometric measurements such as head, chest, mid upper arm circumference and foot length as a screening tool for low birth weight. Chest circumference measured within 7 days of birth appeared to be the most appropriate surrogate of low birth weight with highest sensitivity (75.4%), specificity (78.4%), and positive predictive value (48.9%) as compared with other anthropometric parameters. Low birth weight neonates in absence of weighing scales can be early identified by using simple anthropometric measurements for enhanced home-based care and timely referral.

    Full Text Available Despite increasing professionalism in dog breeding, the physiological range of birth weight in this species remains unclear. Low birth weight can predispose to neonatal mortality and growth deficiencies in humans. To date, the influence of the morphotype on birth weight has never been studied in dogs. For this purpose, an Italian census of birth weight was collected from 3293 purebred pups based on maternal morphotype, size, body weight and breed, as well as on litter size and sex of pups. Multivariate analysis outcomes showed that birth weight (p < 0.001 and litter size (p < 0.05 increased with maternal size and body weight. Birth weight was also influenced by the maternal head and body shape, with brachycephalic and brachymorph dogs showing the heaviest and the lightest pups, respectively (p < 0.001. Birth weight decreased with litter size (p < 0.001, and male pups were heavier than females (p < 0.001. These results suggest that canine morphotype, not only maternal size and body weight, can affect birth weight and litter size with possible practical implications in neonatal assistance.

    To investigate the prevalence of and the perinatal risk factors related to reading difficulty in school-aged very low birth weight infants (VLBWI) with normal intelligence. Subjects were 79 Japanese children in the second to fourth grade of elementary school who had been born at very low birth weight and who regularly visited a follow-up clinic at one of four hospitals. All members had a full-scale IQ score of 80 or higher. Perinatal information was obtained retrospectively from medical records. Each subject underwent four reading tasks, testing monomoratic syllable reading, word reading, non-word reading and short sentence reading. Subjects with an SD reading time score greater than 2.0 in two or more tasks were considered to have reading difficulty (RD). Furthermore we investigated the relations between RD and perinatal factors using logistic regression analysis adjusted for potential confounding factors. Twenty-five (31.6%) out of 79 subjects had RD. We discovered that treated retinopathy of prematurity (tRoP) was a significant risk factor (adjusted OR=5.80, 95% confidence interval=1.51-22.33). The rate of RD in school-aged VLBWI was higher than the estimated prevalence of dyslexia in Japan. Even in children with normal intelligence, long-term developmental follow-up including support for reading skills is necessary for VLBWI. Further investigation is desired to elucidate the relations between visual problems and RD in school-aged children. Copyright © 2016 The Japanese Society of Child Neurology.

    A prominent theoretical view is that the brain is inherently predictive [1, 2] and that prediction helps drive the engine of development [3, 4]. Although infants exhibit neural signatures of top-down sensory prediction [5, 6], in order to establish that prediction supports development, it must be established that deficits in early prediction abilities alter trajectories. We investigated prediction in infants born prematurely, a leading cause of neuro-cognitive impairment worldwide [7]. Prematurity, independent of medical complications, leads to developmental disturbances [8-12] and a broad range of developmental delays [13-17]. Is an alteration in early prediction abilities the common cause? Using functional near-infrared spectroscopy (fNIRS), we measured top-down sensory prediction in preterm infants (born identification of infants at risk and could guide early intervention regimens.

  13. Does visceral osteopathic treatment accelerate meconium passage in very low birth weight infants?- A prospective randomized controlled trial.

    Full Text Available To determine whether the complementary approach of visceral manipulative osteopathic treatment accelerates complete meconium excretion and improves feeding tolerance in very low birth weight infants.This study was a prospective, randomized, controlled trial in premature infants with a birth weight <1500 g and a gestational age <32 weeks who received a visceral osteopathic treatment 3 times during their first week of life or no treatment.Passage of the last meconium occurred after a median of 7.5 days (95% confidence interval: 6-9 days, n = 21 in the intervention group and after 6 days (95% confidence interval: 5-9 days, n = 20, in the control group (p = 0.11. However, osteopathic treatment was associated with a 8 day longer time to full enteral feedings (p = 0.02, and a 34 day longer hospital stay (Median = 66 vs. 100 days i.e.; p=0.14. Osteopathic treatment was tolerated well and no adverse events were observed.Visceral osteopathic treatment of the abdomen did not accelerate meconium excretion in VLBW (very low birth weight-infants. However infants in the osteopathic group had a longer time to full enteral feedings and a longer hospital stay, which could represent adverse effects. Based on our trial results, we cannot recommend visceral osteopathic techniques in VLBW-infants.Clinical trials.gov: NCT02140710.

    The mothers of premature infant born 7 years ago were interviewed regarding memory of neonatal hospitalization during a 40-minute phone interview using a questionnaire exploring emotional feeling and satisfaction. The memory of a high emotional feeling was significantly associated with cranial ultrasound abnormalities in neonatal period, but not outcome. Dissatisfaction was reduced by antenatal maternal hospitalization. We speculate that medical information gathered during perinatal hospitalization explains these relationships.

    Full Text Available Abstract Background It is unclear whether the high rates of low birth weight in South Asia are due to poor fetal growth or short pregnancy duration. Also, it is not known whether the traditional focus on preventing low birth weight has been successful. We addressed these and related issues by studying births in Kaniyambadi, South India, with births from Nova Scotia, Canada serving as a reference. Methods Population-based data for 1986 to 2005 were obtained from the birth database of the Community Health and Development program in Kaniyambadi and from the Nova Scotia Atlee Perinatal Database. Menstrual dates were used to obtain comparable information on gestational age. Small-for-gestational age (SGA live births were identified using both a recent Canadian and an older Indian fetal growth standard. Results The low birth weight and preterm birth rates were 17.0% versus 5.5% and 12.3% versus 6.9% in Kaniyambadi and Nova Scotia, respectively. SGA rates were 46.9% in Kaniyambadi and 7.5% in Nova Scotia when the Canadian fetal growth standard was used to define SGA and 6.7% in Kaniyambadi and Conclusion High rates of fetal growth restriction and relatively high rates of preterm birth are responsible for the high rates of low birth weight in South Asia. Increased emphasis is required on health services that address the morbidity and mortality in all birth weight categories.

    Full Text Available Background Low birth weight (LBW has long been used as an indicator of public health. Low birth weight is not a proxy for any dimension of other maternal or perinatal health outcomes. Low birth weight infants require special care, and have more chronic conditions, learning delays, and attention deficit hyperactivity disorders compared to infants of normal birth weight (NBW. Social competence is viewed as a primary component of healthy function and development and is an important predictor of academic and financial success.Objective To examine social competence of children aged 3-5 years born with low birth weight.Methods This cross-sectional study was undertaken in Palembang in 2012. Subjects consisted of children aged 3-5 years attended a preschool in the Seberang Ulu I District, Palembang, and were divided into two groups: low birth weight (LBW and normal birth weight (NBW. Social competence was assessed by observation and Interaction Rating Scale (IRS and Parenting Style questionnaire (PSQ. Chi-square analysis was used to compare social competence between the two groups. Multivariate regression logistic analysis was used to assess for the dominant factors that may affect a child’s social competence.Results Low birth weight children aged 3 to 5 years had a 1.435 times higher risk of low social competence compared to normal birth weight children of similar age. (RP 1.435; 95%CI 1.372 to 13.507; P=0.019. Multivariate regression logistic analysis revealed that parenting style was a dominant factor affecting social competence.Conclusion Social competence in 3 to 5-year-old children born with low birth weight is lower compared to those with normal birth weight.

    Full Text Available Substantial evidence indicated that low birth weight was an independent risk factor for obesity, impaired glucose regulation, and diabetes later in life. However, investigations into the association between low birth weight and placental microbiome in full-term neonates are limited. Placentas were collected from low birth weight (LBW and normal birth weight (NBW full-term neonates (gestational age 37 w0d–41 w6d consecutively born at Peking Union Medical College Hospital. The anthropometric measurements were measured and 16S ribosomal DNAamplicon high-throughput sequencing were utilized to define bacteria within placenta tissues. It showed that birth weight, ponderal index, head circumference, and placenta weight were significantly lower in LBW than NBW neonates (p < 0.05. The operational taxonomic units (OTUs (p < 0.05 and the estimators of community richness (Chao indexes (p < 0.05 showed a significantly lower diversity in LBW than NBW neonates. There were significant variations in the composition of placenta microbiota between the LBW and NBW neonates at the phylum and genus level. Furthermore, it indicated that Lactobacillus percentage was positively associated with birth weight (r = 0.541, p = 0.025. In conclusion, our present study for the first time detected the relationship between birth weight and placental microbiome profile in full-term neonates. It is novel in showing that the placental microbiome varies in association with low birth weight in full-term neonates.

    We studied the associations of size at birth and prematurity with type 2 diabetes, insulin sensitivity and beta cell function in the Danish population-based Inter99 study (ClinicalTrials.gov NCT00289237). Information about size at birth and prematurity was identified from original midwife records in 4,744 middle-aged Danes. Type 2 diabetes status, insulin sensitivity (Matsuda index) and beta cell function (disposition index) were assessed using a 75 g oral glucose tolerance test. Participants born prematurely were compared with a group of at-term participants born small for gestational age. An increase in birthweight of 1 kg was associated with a 51% (OR 0.49, 95% CI 0.35-0.69) reduced risk of type 2 diabetes. Ponderal index, reflecting thinness at birth, was associated with type 2 diabetes to the same extent as birthweight. The prevalence of type 2 diabetes was increased to a similar degree in participants born prematurely and participants born small for gestational age, although the former had a higher ponderal index at birth. In addition, birthweight z-scores, reflecting fetal growth rate, were unrelated to the risk of type 2 diabetes and to other measures of glucose regulation in participants born prematurely. While low birthweight was inversely associated with insulin sensitivity and beta cell function, prematurity was associated solely with decreased insulin sensitivity. While the association between birthweight and risk of type 2 diabetes is mediated via combined effects on beta cell function and insulin sensitivity, prematurity seems to influence risk of type 2 diabetes via attenuated insulin sensitivity only and independently of fetal growth rates.

    2005-03-01

    Full Text Available Abstract Background Low birth weight (LBW is a public health problem linked to lack of equity in populations. Despite efforts to decrease the proportion of newborns with LBW, success has been quite limited. In recent years, studies focused on explaining how social factors influence this problem have shown that populations with greater inequities have a greater proportion of newborns with LBW. Methods The objective was to describe socioeconomic factors related to LBW adjusted by demographic, reproductive and health services variables in Mexico City. A case-control study was carried out in three hospitals with gynaecological and obstetrics services in Mexico City during the first half of 1996. During the recruiting period all children with LBW (cases, defined as newborns weighing Results We found that low socioeconomic level was the most important risk factor for LBW and was independent of other factors, including those related to reproduction and nutrition, smoking, morbidity during pregnancy, accessibility to health services and prenatal care (OR 2.68; 95% CI 1.19, 6.03. Conclusion We found that socioeconomic factors are relevant to LBW. However further research should be done in different population groups as well as developing precise ways of measuring socioeconomic factors and their role in reproductive health.

    Full Text Available At birth, elevated IGF-I levels have been linked to birth weight extremes; high birth weight and low birth weight are risk factors for adult-onset chronic diseases including obesity, cardiovascular disease, and type 2 diabetes. We examined associations between plasma IGF-I levels and birth weight among infants born to African American and White obese and nonobese women. Prepregnancy weight and height were assessed among 251 pregnant women and anthropometric measurements of full term infants (≥37 weeks of gestation were taken at birth. Circulating IGF-I was measured by ELISA in umbilical cord blood plasma. Linear regression models were utilized to examine associations between birth weight and high IGF-I, using the bottom two tertiles as referents. Compared with infants with lower IGF-I levels (≤3rd tertile, those with higher IGF-I levels (>3rd tertile were 130 g heavier at birth, (β-coefficient=230, se=58.0, P=0.0001, after adjusting for gender, race/ethnicity, gestational age, delivery route, maternal BMI and smoking. Stratified analyses suggested that these associations are more pronounced in infants born to African American women and women with BMI ≥30 kg/m2; the cross product term for IGF-I and maternal BMI was statistically significant (P≤0.0004. Our findings suggest that the association between IGF-I levels and birth weight depends more on maternal obesity than African American race/ethnicity.

    The aim of this study was to investigate the risk factors for preterm births in the Yaounde Gynaeco-Obstetric and Pediatric Hospital in Cameroon, and to describe their outcomes. We conducted a cross-sectional analytical study of hospital records over eight years. The incidence of prematurity was 26.5 % of admissions over a period of 7 years 7 months. After controlling for confounding factors, we identified attending antenatal care visits in a health centre (Odds ratio [OR] 6.19; 95% Confidence interval [CI] 1.15 - 33.22; p = 0.033), having a urinary tract infection (OR 39.04; 95% CI 17.19 - 88.62; p causes of death were neonatal infections (27.6%), neonatal asphyxia (11.9%) and congenital malformations (10.3%). We recommend enhanced prenatal care and management of pathologies which arise during pregnancy.

    Full Text Available Abstract Background Azithromycin reduces the severity of illness in patients with inflammatory lung disease such as cystic fibrosis and diffuse panbronchiolitis. Bronchopulmonary dysplasia (BPD is a pulmonary disorder which causes significant morbidity and mortality in premature infants. BPD is pathologically characterized by inflammation, fibrosis and impaired alveolar development. The purpose of this study was to obtain pilot data on the effectiveness and safety of prophylactic azithromycin in reducing the incidence and severity of BPD in an extremely low birth weight (≤ 1000 grams population. Methods Infants ≤ 1000 g birth weight admitted to the University of Kentucky Neonatal Intensive Care Unit (level III, regional referral center from 9/1/02-6/30/03 were eligible for this pilot study. The pilot study was double-blinded, randomized, and placebo-controlled. Infants were randomized to treatment or placebo within 12 hours of beginning mechanical ventilation (IMV and within 72 hours of birth. The treatment group received azithromycin 10 mg/kg/day for 7 days followed by 5 mg/kg/day for the duration of the study. Azithromycin or placebo was continued until the infant no longer required IMV or supplemental oxygen, to a maximum of 6 weeks. Primary endpoints were incidence of BPD as defined by oxygen requirement at 36 weeks gestation, post-natal steroid use, days of IMV, and mortality. Data was analyzed by intention to treat using Chi-square and ANOVA. Results A total of 43 extremely premature infants were enrolled in this pilot study. Mean gestational age and birth weight were similar between groups. Mortality, incidence of BPD, days of IMV, and other morbidities were not significantly different between groups. Post-natal steroid use was significantly less in the treatment group [31% (6/19] vs. placebo group [62% (10/16] (p = 0.05. Duration of mechanical ventilation was significantly less in treatment survivors, with a median of 13 days (1–47

    Low birth weight remains the primary cause of neonatal morbidity and mortality in the United States. We examined whether maternal happiness about a pregnancy, in addition to her report of the father's happiness, predicts birth weight and risk for low birth weight (happiness about the pregnancy was measured before 21 weeks' gestation on a scale from 1 to 10 (1 to 3 unhappy, 4 to 7 ambivalent, or 8 to 10 happy). "Mother reports partner happier" occurred when the mother perceived the father's happiness score at least 5 points greater than her own. Information on birth weights and maternal sociodemographic, medical, and psychosocial factors were obtained from surveys and medical records. Of 162 live births, 9 were low birth weight (5.6%). Compared with women who reported happiness with the pregnancy, risk for low birth weight was greater when the mother reported partner happier about the pregnancy (relative risk 10.0, 95% confidence interval, 3.1-32.4). This predictor of birth weight remained significant in multivariate linear regression analyses (coefficient = -472 g, SE = 171 g, P = .007) after adjustment for other known predictors of birth weight. Maternal report of greater partner happiness about a pregnancy is associated with birth weight and appears to define low- and high-risk subgroups for low birth weight in a low-income population. Further study in larger samples is needed to confirm our findings and to assess whether maternal report of greater partner happiness is itself a modifiable factor or is a marker for other factors that might be modified with targeted interventions.

    Full Text Available Abstract Introduction Klebsiella pneumoniae is in most cases a hospital-acquired infection and presents as pneumonia, septicemia and meningitis in patients with some predisposing factors, including prematurity, intravenous catheter, history of antibiotic therapy and intravenous nutrients. Case presentation A low-birth-weight, 33-day-old Caucasian girl with respiratory distress syndrome was admitted to our hospital. She developed septicemia, meningitis, polyarticular arthritis and osteomyelitis by nosocomial K. pneumoniae which was resistant to most antibiotics except ciprofloxacin. She was therefore treated with ciprofloxacin and co-trimoxazole for eight weeks. After completion of the treatment course, she completely improved with excellent weight gain and without any adverse effects during three years of follow-up. Conclusion In the resistant strain of K. pneumoniae, ciprofloxacin could be considered as a therapeutic option with the prospect of a good outcome, even in neonates and infants.

    2008-12-01

    A retrospective study using maternal and birth statistics from an open, captive rhesus macaque colony was done to determine the effects of parity, exposure to simian retrovirus (SRV), housing, maternal parity, and maternal birth weight on infant birth weight, viability and gestation length. Retrospective colony statistics for a 23-y period indicated that birth weight, but not gestation length, differed between genders. Adjusted mean birth weights were higher in nonviable infants. Mothers positive for SRV had shorter gestations, but SRV exposure did not affect neonatal birth weights or viability. Infants born in cages had longer gestations than did those born in pens, but neither birth weight nor viability differed between these groups. Maternal birth weight did not correlate with infant birth weight but positively correlated with gestation length. Parity was correlated with birth weight and decreased viability. Increased parity of the mother was associated with higher birth weight of the infant. A transgenerational trend toward increasing birth weight was noted. The birth statistics of this colony were consistent with those of other macaque colonies. Unlike findings for humans, maternal birth weight had little predictive value for infant outcomes in rhesus macaques. Nonviable rhesus infants had higher birth weights, unlike their human counterparts, perhaps due to gestational diabetes occurring in a sedentary caged population. Similar to the situation for humans, multiparity had a protective effect on infant viability in rhesus macaques.

    Full Text Available The aim of this study was to evaluate if the Kangaroo Mother Care (KMC interferes in the gain of weight and in the hospital length stay of the low birth weight preterm newborn (LWBPTN. For this, it was realized an analytic retrospective study, through the evaluation of the medical records of 60 LWBPTN with born weight less than 2000 g that received assistance by KMC, for a period of 2 hours per day and, 60 LWBPTN that received assistance by the Traditional Method of Care (TMC, admitted in the unity of neonatal intensive care and unity of premature of a private maternity in the city of Ribeirão Preto-SP, Brazil, comparing the gain of weight and the hospital length stay. We did not find differences statistically significant in relation to the gain of weight of the LWBPTN assisted by KMC, in relation to LWBPTN assisted by the TMC, 15,8 and 14,9 g/per day, respectively. In relation to the time of admission, we also did not find differences statistically significant, 27,3 and 26,2 days, for the LWBPTN in the KMC and TMC, respectively, although in the stratification of the sample, the LBWPTN with pregnancy age < 30 weeks or birth weight < 1500 g left the hospital 3 days earlier in the KMC. It was concluded that the KMC, in the conditions of this study, it seems not to interfere significatively in the gain of weight and in the time of admission of LWBPTN. We emphasize that the utilization of KMC in the assistance to the LWBPTN of low weight is a viable model, even for the private health institution.

    Low birth weight predicts compromised cognitive ability. We used data from the 1958 National Child Development Study (NCDS), the 1970 British Cohort Study (BCS), and the 2000–2002 Millennium Cohort Study (MCS) to analyze how this association has changed over time. Birth weight was divided into two categories, <2,500 g (low) and 2,500–4,500 g (normal) and verbal cognitive ability was measured at the age of 10 or 11 y. A range of maternal and family characteristics collected at or soon after the time of birth were considered. Linear regression was used to analyze the association between birth weight and cognitive ability in a baseline model and in a model that adjusted for family characteristics. The standardized difference (SD) in cognitive scores between low-birth-weight and normal-birth-weight children was large in the NCDS [−0.37 SD, 95% confidence interval (CI): −0.46, −0.27] and in the BCS (−0.34, 95% CI: −0.43, −0.25) cohorts, and it was more than halved for children born in the MCS cohort (−0.14, 95% CI: −0.22, −0.06). The adjustment for family characteristics did not explain the cross-cohort differences. The results show that the association between low birth weight and decreased cognitive ability has declined between the 1950s and 1970s birth cohorts and the 2000--2002 birth cohort, despite a higher proportion of the low-birth-weight babies having a very low birth weight (<1,500 g) in the more recent birth cohort. Advancements in obstetric and neonatal care may have attenuated the negative consequences associated with being born small. PMID:27994141

    Surgical skill and strategy for the correction of tetralogy of Fallot (TOF) have improved and resulted in satisfactory outcomes. However, prematurity and low birth weight continue to remain risk factors for poor outcomes. We present a case of a 2,150 g neonate born with TOF, in whom palliation was achieved with right ventricular outflow tract (RVOT) stenting. Seventy-seven days after the procedure, stenosis of RVOT below the stent was identified. At that time his body weight was 4.9 kg and total corrective surgery was deemed feasible. Eight months following surgical repair, the patient remained well without medical intervention. RVOT stenting may be a viable interim procedure while waiting for a low birth weight neonate born with TOF and prostaglandin E1 dependency to reach optimal weight to undergo corrective surgery.

    Full Text Available Abstract Background The foetal growth standards for Indian children which are available today suffer due to methodological problems. These are, for example, not adhering to the WHO recommendation to base gestational age on the number of completed weeks and secondly, not excluding mothers with risk factors. This study has addressed both the above issues and in addition provides birthweight reference ranges with regard to sex of the baby and maternal parity. Methods Data from the labour room register from 1996 to 2010 was obtained. A rotational sampling scheme was used i.e. the 12 months of the year were divided into 4 quadrants. All deliveries in January were considered to represent the first quadrant. Similarly all deliveries in April, July and October were considered to represent 2nd, 3rd and 4th quadrants. In each successive year different months were included in each quadrant. Only those mothers aged 20–39 years and delivered between 24 to 42 weeks gestational age were considered. Those mothers with obstetric risk factors were excluded. The reference standards were fitted using the Generalized Additive Models for Location Scale and Shape (GAMLSS method for Box – Cox t distribution with cubic spline smoothing. Results There were 41,055 deliveries considered. When women with risk factors were excluded 19,501 deliveries could be included in the final analysis. The male babies of term firstborn were found to be 45 g heavier than female babies. The mean birthweights were 2934 g and 2889.5 g respectively. Similarly, among the preterm babies, the first born male babies weighed 152 g more than the female babies. The mean birthweights were 1996 g and 1844 g respectively. In the case of later born babies, the term male babies weighed 116grams more than the females. The mean birth weights were 3085 grams and 2969 grams respectively. When considering later born preterm babies, the males outweighed the female babies by 111 grams. The

    Full Text Available Recent surveillance data suggest that mean birth weight has begun to decline in several developed countries. The aim of this study is to examine the changes in birth weight among singleton live births from 2002 to 2012 in Guangzhou, one of the most rapidly developed cities in China.We used data from the Guangzhou Perinatal Health Care and Delivery Surveillance System for 34108 and 54575 singleton live births with 28-41 weeks of gestation, who were born to local mothers, in 2002 and 2012, respectively. The trends in birth weight, small (SGA and large (LGA for gestational age and gestational length were explored in the overall population and gestational age subgroups.The mean birth weight decreased from 3162 g in 2002 to 3137 g in 2012 (crude mean difference, -25 g; 95% CI, -30 to -19. The adjusted change in mean birth weight appeared to be slight (-6 g from 2002 to 2012 after controlling for maternal age, gestational age, educational level, parity, newborn's gender and delivery mode. The percentages of SGA and LGA in 2012 were 0.6% and 1.5% lower than those in 2002, respectively. The mean gestational age dropped from 39.2 weeks in 2002 to 38.9 weeks in 2012. In the stratified analysis, we observed the changes in birth weight differed among gestational age groups. The mean birth weight decreased among very preterm births (28-31 weeks, while remained relatively stable among other gestational age subcategories.Among local population in Guangzhou from 2002 to 2012, birth weight appeared to slightly decrease. The percentage of SGA and LGA also simultaneously dropped, indicating that newborns might gain a healthier weight for gestational age.

    A prospective study of 199 children with birth weight less than 1,500 g was done. 86 boys and 113 girls, 141 (71%) adequate for gestational age and 58 (29%) small for gestational age. At follow-up 43 (21.6%) infants were lost to control, 17 (7%) moved to other places and 7 (3.5%) died in the first year of life. In the first year of life, infants whose birthweights were adequate for gestational age had been hospitalized more frequently and the small for dates showed higher percentage of undernutrition. After the second year of life, it was possible to know the impairment. It was found 7.4% of cerebral palsy, 2.9% of hipoacusia and 2.2% of retinopathy of prematurity, these diagnosis were most frequent in children that were adequate for gestational age. We concluded that small for dates infants are at risk of undernutrition and that those adequate for gestational age are at risk of permanent sequelae.

    Biological motion perception can be assessed using a variety of tasks. In the present study, 8- to 11-year-old children born prematurely at very low birth weight (body structure, and the ability to carry out higher order processes required for action recognition and person identification. Preterm children exhibited difficulties in all 4 aspects of biological motion perception. However, intercorrelations between test scores were weak in both full-term and preterm children--a finding that supports the view that these processes are relatively independent. Preterm children also displayed more autistic-like traits than full-term peers. In preterm (but not full-term) children, these traits were negatively correlated with performance in the task requiring structure-from-motion processing, r(30) = -.36, p children and suggest that a core deficit in social perception/cognition may contribute to the development of the social and behavioral difficulties even in members of this population who are functioning within the normal range intellectually. The results could inform the development of screening, diagnostic, and intervention tools.

    Children born prematurely at very low birth weight (<1500 g) are at increased risk for impairments affecting social functioning, including autism spectrum disorders (e.g., Johnson et al., 2010). In the current study, we used the Happé-Frith animated triangles task (Abell, Happé, & Frith, 2000) to study social attribution skills in this population. In this task, typical viewers attribute intentionality and mental states to shapes, based on characteristics of their movements. Participants included 34 preterm children and 36 full-term controls, aged 8-11 years. Groups were comparable in terms of age at test, gender, handedness, and socioeconomic status; they also performed similarly on tests of selective attention/processing speed and verbal intelligence. Relative to full-term peers, preterm children's descriptions of the animations were less appropriate overall; they also overattributed intentionality/mental states to randomly moving shapes and underattributed intentionality/mental states to shapes that seemed to be interacting socially. Impairments in the ability to infer the putative mental states of triangles from movement cues alone were most evident in children displaying more "autistic-like" traits, and this may reflect atypical development of and/or functioning in, or atypical connections between, parts of the social brain.

    BACKGROUND: Birth weight has inconsistent associations with colorectal cancer, possibly due to different anatomic features of the colon versus the rectum. The aim of this study was to investigate the association between birth weight and colon and rectal cancers separately. METHODS: 193,306 children......, born from 1936 to 1972, from the Copenhagen School Health Record Register were followed prospectively in Danish health registers. Colon and rectal cancer cases were defined using the International Classification of Disease version 10 (colon: C18.0-18.9, rectal: 19.9 and 20.9). Only cancers classified....... No significant sex differences were observed; therefore combined results are presented. Birth weight was positively associated with colon cancers with a HR of 1.14 (95% CI, 1.04-1.26) per kilogram of birth weight. For rectal cancer a significant association was not observed for birth weights below 3.5kg. Above 3...

    Prematurity is frequently seen in the neonatal intensive care unit, and trisomy 21 is an often diagnosed neonatal disorder. We report a unique case of extremely premature twins, one of whom was ultimately diagnosed with trisomy 21. We were able to examine the neonatal courses and outcomes of these twins, which were similar despite the presence of trisomy 21 in one twin. This is the first report comparing the neonatal course of an infant with trisomy 21 to an unaffected twin in patients born s...

    Congenital malaria is assumed to be a risk factor for infant morbidity and mortality in endemic areas like Maumere, Indonesia. Infected infants are susceptible to its impact such as premature labor, low birth weight, anemia, and other unspecified symptoms. The aim of this study was to investigate the prevalence of congenital malaria and the influence of mother-infant paired parasite densities on the clinical outcome of the newborns at TC Hillers Hospital, Maumere. An analytical cross sectional study was carried out in newborns which showed criteria associated with congenital malaria. A thick and thin blood smear confirmed by nested PCR was performed in both mothers and infants. The association of congenital malaria with the newborn's health status was then assessed. From 112 mother-infant pairs included in this study, 92 were evaluated further. Thirty-nine infants (42.4%) were found to be infected and half of them were asymptomatic. Infected newborns had a 4.7 times higher risk in developing anemia compared to uninfected newborns (95% CI, 1.3-17.1). The hemoglobin level, erythrocyte amount, and hematocrit level were affected by the infants' parasite densities (Pmalaria, the prevalence is almost 3 times higher than in an unselected collective. Low birth weight, anemia, and pre-term birth were the most common features. Anemia seems to be significantly influenced by infant parasite densities but not by maternal parasitemia.

    Infant birth weight, which is classified into low birth weight, normal birth weight and macrosomia, is associated with short and long-term health consequences, such as neonatal mortality and chronic disease in life. Macrosomia and low birth weight are double burden problems in developing counties, such as Ethiopia, but the paucity of evidence has made it difficult to assess the extent of this situation. As a result there has been inconsistency in the reported prevalence of low birth weight and macrosomia in Ethiopia. This study aimed to determine the incidence and predictors of low birth weight and macrosomia in Tigray, Northern Ethiopia. We conducted a cross-sectional survey among a cohort of 1152 neonates delivered in Tigray Region at randomly selected hospitals between April and July 2014. We used the birth weight category described previously as an outcome variable. Data were collected using structured questionnaire by midwives. We entered and analyzed data using STATA™ Version 11.0. Data were described using a frequency, percentage, relative risk ratio, and 95% confidence interval. Multinomial logistic regression was conducted to identify independent predictors of low birth weight and macrosomia. In this study, we found a 10.5% and 6.68% incidence of low birth weight and macrosomia, respectively. Seventy (57.8%) of all low birth weight neonates were term births. The predictors for low birth weight were: early marriage (macrosomia were: female gender (RRR: 0.58, CI: 0.35-0.9); high body mass index (RRR: 5.0, CI: 1.56-16); post-maturity (RRR: 2.23, CI: 1.06-4.6); and no maternal complication (RRR: 0.46, CI: 0.27-0.8). In this study, we found gestational age and gender of the neonate to be common risk factors for both low birth weight and macrosomia. Strengthening antenatal follow up, prevention of pre and post maturity, controlling body mass index, and improving socioeconomic status of mothers are recommendations to prevent the double burden (low birth weight

    Low birth weight is associated with increased risk for Attention-Deficit/Hyperactivity Disorder (ADHD); however, the etiological underpinnings of this relationship remain unclear. This study investigated if genetic variants in angiogenic, dopaminergic, neurotrophic, kynurenine, and cytokine-related biological pathways moderate the relationship between birth weight and ADHD symptom severity. A total of 398 youth from two multi-site, family-based studies of ADHD were included in the analysis. The sample consisted of 360 ADHD probands, 21 affected siblings, and 17 unaffected siblings. A set of 164 SNPs from 31 candidate genes, representing five biological pathways, were included in our analyses. Birth weight and gestational age data were collected from a state birth registry, medical records, and parent report. Generalized Estimating Equations tested for main effects and interactions between individual SNPs and birth weight centile in predicting ADHD symptom severity. SNPs within neurotrophic (NTRK3) and cytokine genes (CNTFR) were associated with ADHD inattentive symptom severity. There was no main effect of birth weight centile on ADHD symptom severity. SNPs within angiogenic (NRP1 & NRP2), neurotrophic (NTRK1 & NTRK3), cytokine (IL16 & S100B), and kynurenine (CCBL1 & CCBL2) genes moderate the association between birth weight centile and ADHD symptom severity. The SNP main effects and SNP × birth weight centile interactions remained significant after adjusting for multiple testing. Genetic variability in angiogenic, neurotrophic, and inflammatory systems may moderate the association between restricted prenatal growth, a proxy for an adverse prenatal environment, and risk to develop ADHD.

    Full Text Available The objective of this study was to evaluate the effect of the size class of the litter at birth on the variation in birth and weaning weights and on the survival rate of piglets from birth to weaning. For this purpose, records of individual weight at birth and weaning of piglets obtained from a database of 295 Landrace litters born between 2000 and 2010 on a pig farm in the western region of the State of Paraná were used. The litters were classified as small (up to 7 piglets, medium (8 to 13 piglets, and large (> 14 piglets according to the total number of piglets born. The data were analyzed considering the effects of the year of sow mating and size class of the litter at birth. The correlations between mean weight and variance in litter weight and size were higher for medium and large litters. The size class of the litter significantly influenced the mean weight of piglets at birth and weaning and the variance in birth weight. Piglets born in medium and large litters weighed less and exhibited greater birth weight variation and a lower survival rate until weaning than piglets born in small litters.

    This paper examined the relationship between birth weight, precipitation, and temperature in 19 African countries. We matched recorded birth weights from Demographic and Health Surveys covering 1986 through 2010 with gridded monthly precipitation and temperature data derived from satellite and ground-based weather stations. Observed weather patterns during various stages of pregnancy were also used to examine the effect of temperature and precipitation on birth weight outcomes. In our empirical model we allowed the effect of weather factors to vary by the dominant food production strategy (livelihood zone) in a given region as well as by household wealth, mother's education and birth season. This allowed us to determine if certain populations are more or less vulnerable to unexpected weather changes after adjusting for known covariates. Finally we measured effect size by observing differences in birth weight outcomes in women who have one low birth weight experience and at least one healthy birth weight baby. The results indicated that climate does indeed impact birth weight and at a level comparable, in some cases, to the impact of increasing women's education or household electricity status.

    Full Text Available Pregnancies resulting in very small or very large babies are at higher risk of obstetric complications with increased morbidity for both mother and baby. Using data from the Medical Birth Registry of Norway we have shown how human birth weight is still subject to stabilizing selection. Particular combinations of maternal/fetal immune genes have been implicated in pregnancies resulting in a low birth weight baby (<5th birth weight centile. More specifically, an inhibitory maternal KIRAA genotype with a paternally derived fetal HLA-C2 ligand. At the other end of the birth weight spectrum the presence of an activating maternal KIR2DS1 gene is associated with increased birth weight in linear or logistic regression analyses of all pregnancies >5th centile (p=0.005, OR=2.65. Thus, inhibitory maternal KIR combined with fetal HLA-C2 is more frequently associated with low birth weight, whereas activating maternal KIR with fetal HLA-C2 ligand is associated with increasing birth weight. Our findings using the MoBa cohort have replicated the association of KIR and HLA-C seen in poor placentation, and confirm the importance of maternal/fetal immune gene interactions in determining the outcome of pregnancy.

    Birth weight (BW) is a medium- and long-term risk determinant of cardiovascular risk factors. To assess the association between BW and cardiovascular risk factors in adolescents of the city of Salvador, Bahia state. Cross-sectional study with comparison of BW groups. Sample comprising 250 adolescents classified according to the BMI as follows: high-normal (≥ 50th percentile and < 85th percentile); overweight (≥ 85th percentile and < 95th percentile); and obesity (≥ 95th percentile). The risk variables compared were as follows: waist circumference (WC); arterial blood pressure; lipid profile; glycemia; serum insulin; HOMA-IR; and metabolic syndrome. The BW was informed by parents and classified as follows: low (BW ≤ 2,500g); normal (BW > 2,500g and < 4,000g); and high (BW ≥ 4,000g). One hundred and fifty-three (61.2%) girls, age 13.74 ± 2.03 years, normal BW 80.8%, low BW 8.0%, and high BW 11.2%. The high BW group as compared with the normal BW group showed a higher frequency of obesity (42.9%, p=0.005), elevated SBP and DBP (42.9%, p=0.000 and 35.7%, p=0.007, respectively), and metabolic syndrome (46.4%, p=0.002). High BW adolescents as compared with normal BW adolescents had a prevalence ratio for high SBP 3.3 (95% CI: 1.7-6.4) and obesity 2.6 (95% CI: 1.3-5.2). The WC of high BW adolescents was 83.3 ± 10.1 (p=0.038). The lipid profile showed no statistically significant differences. Our findings suggest that obesity, elevated SBP and DBP, and metabolic syndrome during adolescence might be associated with high BW.

    Observationally, lower birth weight is usually associated with poorer academic performance; whether this association is causal or the result of confounding is unknown. To investigate this question, we obtained an effect estimate, which can have a causal interpretation under specific assumptions, of birth weight on educational attainment using instrumental variable analysis based on single nucleotide polymorphisms determining birth weight combined with results from the Social Science Genetic Association Consortium study of 126,559 Caucasians. We similarly obtained an estimate of the effect of birth weight on academic performance in 4,067 adolescents from Hong Kong's (Chinese) Children of 1997 birth cohort (1997-2016), using twin status as an instrumental variable. Birth weight was not associated with years of schooling (per 100-g increase in birth weight, -0.006 years, 95% confidence interval (CI): -0.02, 0.01) or college completion (odds ratio = 1.00, 95% CI: 0.96, 1.03). Birth weight was also unrelated to academic performance in adolescents (per 100-g increase in birth weight, -0.004 grade, 95% CI: -0.04, 0.04) using instrumental variable analysis, although conventional regression gave a small positive association (0.02 higher grade, 95% CI: 0.01, 0.03). Observed associations of birth weight with academic performance may not be causal, suggesting that interventions should focus on the contextual factors generating this correlation. © The Author 2017.

    Full Text Available Background. Socioeconomic status and birth weight are prominent factors for future growing of children. Also Studies show that this criterion is associated with reduced cognitive outcomes, school achievement, and adult work capacity. So in this paper we determined the effects of some socio-economic statuses and birth weight on physical growth of children in Mashhad, Iran. Method and materials. This is a cross sectional study that determined effect of socio-economic status and birth weight on weight, heighting and BMI of school age children. Healthy six years old children who were screened before enter, to school were eligible for participating in our study between 6 June 2006 and 31 July. Weight and standing height were documented at birth and measured at 6 years old. Then, their BMI were calculated in childhood period. Data were analyzed by using SPSS software. Result. Results show that some socio-economic variables and birth weight is associated with and, perhaps, influence the variation of growth in the children. The variables which show the most consistent and significant association were birth weight, sex, economic status and education of parents. Conclusion. In this paper, we found that birth weight, economic status and education parents of neonates have directly significant effect on growth childhood period. We recommended that paying attention to these criteria for improving growth of children in our society should be considered by authorities.

    Full Text Available The objectives of this study were to comprehend the breastfeeding process from reports of mothers of premature babies and identify factors facilitating or complicating this process. A descriptive qualitative study regarding the family centered care. We conducted 12 interviews with mothers of six months premature babies of chronological age and we submitted data to content analysis. Four categories emerged: The previous breastfeeding experience in the process of breastfeeding the premature baby; Emotional context versus the breastfeeding process; The ability to manage breastfeeding the premature baby and, Successes and failures. We concluded that family and professional support, adequate management and the welcoming of individualized services in the prematurity context were majorly responsible for the breastfeeding success, being even able to surpass the previous maternal desire. Breastfeeding accompaniment after discharge is indispensable for its success with premature babies.

    Cervical incompetence it's a dilatation of the cervix during the third trimester of pregnancy that ends with the interruption of it. The incidence in Chile is about 0.1-2% of the total pregnancies and it's one of the causes of preterm birth. A 34 years old pregnant patient. Timectomized at age 18 to treat her miastenia gravis, previously trated with medication, had 4 previous preterm labours all of them under 25 weeks and vaginal births. All fetuses died postpartum. A cerclage was made during the third, fourth and fifth pregnancies. She didn't present hypertension during the gestation and no cervical diameter under 15mm. Since the fourth gestation the following tests are taken: Antifosfolipidic antibodies, APTT,PT. All the results are either normal or negative. Microbial cultures were negative. No amniocentesis was made. A McDonald cervical cerclage was made during pregnancies number 3, 4 and 5 on the 16th week to delay the labor. Also oral micronized progesterone, on a 400mg/24 hours dosis, was administered to avoid preterm birth. On the 24th week the pharmacological treatment started including Intramuscular Betamethasone, 12 mg/24 hours (2 doses), to induce lung maturity on the fetus. It is thought that the administration of progesterone could have improved the situation of the patient, because it acts as a labour repressants. The use of cerclage could have helped, but the factors that may influence the effectiveness of this method are unknown. Perhaps there is some immunologic factor associated with the miastenia gravis that alters the normal course of pregnancy.

    Full Text Available Background: This study aimed to assess the incidence and survival rates of neonates weighing less than 2500g for duration of the first 28 days in an Iranian community.Methods: In this prospective longitudinal study, all neonates with birth weight less than 2500g were selected from the list of all neonates born in the only public-sector referral hospital, for a six months period. The weight of neonates at birth along with some demographic variables was recorded on a checklist. A cohort of neonates with birth weight less than 2500g were followed for 28 days. Mortality within 28 days of birth was used as end point. Continuous variables were summarized using mean and 95% confidence intervals, while categorical variables were presented as ratios and percentages.Results: About 1750 neonates were born of which 168 neonates with birth weights less than 2500g were recorded giving a proportion of 9.6%. Of 168 neonates, 21 (12.5% had very low birth weights (VLBW (birth weights<1500g. Survival rates for the groups of LBW (1500<birth weights<2500g and VLBW neonates were 98.4% and 66.6%, respectively. Regression analysis showed birth weight has, unsurprisingly, the most effect (beta= 0.501 on the survival rate among variables studied in this research.Conclusion: The survival rate among VLBW births in our study is dramatically low (66.6%. Not only attempts must be made to reduce the incidence and prevalence of this problem but also we need to work on the related factors of neonates' survival rate in this community.

    Evaluation of policy and treatment of deliveries at the limits of viability in the Netherlands and resulting survival figures. Cohort study. Within the framework of the European 'Models of organising access to intensive care for very preterm births in Europe' (MOSAIC) study, data was collected on all 512 births in 2003 (terminations excluded) following 22-31 weeks gestation in the catchment areas of the perinatal centres in Nijmegen and Utrecht, the Netherlands. Gynaecologists and neonatologists practised a reserved policy for the active treatment of pregnancies under 25 weeks (5/77; 6%); all infants died. At 25 weeks, an active obstetric policy was used in one quarter of pregnancies, but none of the infants survived. Even at 26 weeks pregnancy, the obstetric policy was reserved and the mortality relatively high (9/31; 29%). From the neonatal deaths, 86 out of 92 (93%) were preceded by a decision either not to start or to discontinue treatment. Dutch obstetricians and neonatologists practised a reserved policy at the limits of neonatal viability. There is more need for active antenatal transfer to perinatal centres for those at the lower limit of neonatal viability to enable well-balanced decisions to take place. The parents' wishes should always be taken into account.

    Full Text Available INTRODUCTION: Birth weight is an indicator of both neonatal morbidity and mortality, maternal health, nutrition and quality of antenatal services. OBJECTIVE: To find out important anthropometric parameter(s in the newborn as related to birth weight so that newborns with low birth weight can be identified. MATERIAL AND METHODS: A prospective cross sectional, analytical, hospital based study was conducted at Amritsar on 200 term low birth weight newborn babies(<2.5 kg born during a period of 10 months and their various anthropometric measurements (HC, CC, MAC, TC, CFC were taken according to standard techniques. RESULTS: The study showed a strong correlation (p <0.001 between mid-arm circumference (r=0.834 and birth weight, followed by head circumference (r=0.816 and birth weight. Other parameters were also strongly correlated (p < 0.001. A value of <9.2 cm and <7.6 cm for mid-arm circumference showed highest validity for picking up newborns weighing <2500 gm and <2000 gm respectively. CONCLUSION: Measurement of arm circumference is easier, convenient and statistically superior to other anthropometrical parameters in detection of low birth weight newborn babies. The researchers recommend designing of a simple 'Tri-colored tape' for early detection of 'At Risk' LBW newborns in rural communities for their timely management.

    We aimed to determine the relationship between dioxin congeners in maternal breast milk and maternal glucocorticoid levels with newborn birth weight after nearly 45 years of use of herbicides in the Vietnam War. The study subjects comprised 58 mother-infant pairs in a region with high dioxin levels in the soil (hotspot) and 62 pairs from a control region. Dioxin levels in maternal breast milk were measured by HRGC-HRMS. Salivary glucocorticoid levels were determined by LC-MS/MS. Dioxin congener levels in mothers from the hotspot were found to be two to fivefold higher than those in mothers from the control region. Birth weight was inversely correlated with 2,3,7,8-TeCDD and 2,3,4,7,8-PeCDF congener levels. The rate of newborns whose birth weight was less than 2500 g was threefold higher in the hotspot (12 %) than in the control region (4 %). Salivary glucocorticoid levels in mothers with low birth weight infants were significantly higher than those in the normal birth weight group. Low
