    1990-01-01

    The physical and emotional condition of the mother delivering a premature or low birth weight infant may be quite different than that of the mother of a healthy term infant when initiating breast-feeding. Despite this difference, incidence and duration of lactation among mothers of pre-term or low birth weight infants was found to be quite good compared with that of mothers of term infants. Considerable problems, however, are encountered by premature or low birth weight infants when breast-fe...

    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.

    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.

    2006-01-01

    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 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.

    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.

    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 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.

    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.

    Phthalate exposure is widespread among pregnant women but whether it is related to fetal growth and birth weight remains to be determined. We examined whether first trimester prenatal phthalate exposure was associated with birth weight in a pregnancy cohort study. We recruited first trimester pregnant women from 2010–2012 from four centers and analyzed mother/infant dyads who had complete urinary phthalate and birth record data (N = 753). We conducted multiple linear regression to examine if prenatal log specific gravity adjusted urinary phthalate exposure was related to birthweight in term and preterm (≤37 weeks) infants, stratified by sex. We observed a significant association between mono carboxy-isononyl phthalate (MCOP) exposure and increased birthweight in term males, 0.13 kg (95% CI 0.03, 0.23). In preterm infants, we observed a 0.49 kg (95% CI 0.09, 0.89) increase in birthweight in relation to a one log unit change in the sum of di-ethylhexyl phthalate (DEHP) metabolite concentrations in females (N = 33). In summary, we observed few associations between prenatal phthalate exposure and birthweight. Positive associations may be attributable to unresolved confounding in term infants and limited sample size in preterm infants. PMID:27669283

    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 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.

    2012-01-01

    Eruption of green, discolored teeth affecting the primary dentition has been described in association with congenital viral infection, sepsis, hemolytic jaundice, and cholestasis. The purpose of this paper was to present the cases of 3 extremely low birth weight preterm infants who were noted to have green teeth at the corrected ages of 10 to 12 months. All had a history of prolonged conjugated hyperbilirubinemia during their time in neonatal intensive care. For infants with prolonged conjugated hyperbilirubinemia, extreme preterm birth and/or extremely low birth weight may be additional risk factors predisposing to the eruption of green teeth in later infancy.

    Full Text Available Objective - Recommendations for immunoprophylaxis in low-birth-weight (LBW infants born to hepatitis B surface antigen (HBsAg-positive mothers vary. We successfully immunized an HBsAg-exposed infant (birth weight: 400 g and performed a literature review on the outcome of postexposure immunoprophylaxis in HBsAg-exposed preterm and LBW infants. Methods - By use of PubMed we identified articles relevant to the topic. Studies were included if the intended vaccine schedule was completed and follow-up data were reported. Results - Antibody response was reported in 31 LBW infants (birth weight < 2,500 g and 49 infants with gestational age of < 38 weeks. Low anti-HBs antibody levels (< 100 IU/L were found in 9 (29% of the 31 LBW infants. Overall, 2 of 20 (10% preterm infants and 2 of 17 (12% LBW were HBsAg-positive on follow-up. In one study, none of the 26 exposed very LBW infants became infected. Conclusion - Due to heterogeneity in immunization schedules, lack of information on transmission rates, and the small number of included subjects, no firm conclusions can be drawn regarding the optimal postexposure prophylaxis in LBW infants. We propose that active and passive immunization at birth should be completed by three further active doses (0–1–2–12 month schedule until further prospective studies are available.

    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.

    Full Text Available Background: Neonatal deaths account for 40% of deaths under the age of 5 years worldwide. Therefore, efforts to achieve the UN Millennium Development Goal 4 of reducing childhood mortality by two-thirds by 2015 are focused on reducing neonatal deaths in high-mortality countries. The aim of present study was to determine death factors among very low-birth-weight infants by path method analysis. Materials and Methods: In this study, medical records of 2,135 infants admitted between years 2008 and 2010 in neonatal intense care unit of Alzahra Educational-Medical centre (Tabriz, Iran were analysed by path method using statistical software SPSS 18. Results: Variables such as duration of hospitalisation, birth weight, gestational age have negative effect on infant mortality, and gestational blood pressure has positive direct effect on infant mortality that at whole represented 66.5% of infant mortality variance (F = 1018, P < 0.001. Gestational age termination in the positive form through birth weight, and also gestational blood pressure in negative form through hospitalisation period had indirect effect on infant mortality. Conclusion: The results of the study indicated that the duration of low-birth-weight infant′s hospitalisation is also associated with infant′s mortality (coefficient -0.7; P < 0.001. This study revealed that among the maternal factors only gestational blood pressure was in relationship with infants′ mortality.

    This paper makes use of data collected in a randomised controlled trial that was designed to test the efficacy of postpartum breastfeeding counselling to increase exclusive breastfeeding among term low birth weight infants in Manila during the first six months. Mothers were randomised to a control group or one of two home visit interventions: by trained breastfeeding counsellors or child care counsellors without breastfeeding support training. Sixty mothers received peer breastfeeding counselling while a further 119 mothers did not. The median duration of exclusive breastfeeding among mothers who received counselling was five weeks versus two weeks among those who received no counselling (pbreastfeeding was interrupted to offer infants water, traditional herbal extracts or artificial baby milk. Mothers who interrupted exclusive breastfeeding claimed they had insufficient milk or that their infants had slow weight gain. Early and sustained breastfeeding support will enable mothers to exclusively breastfeed low birth weight infants for the first six months.

    Very low birth weight (VLBW) infants' survival has greatly increased in the last few decades thanks to the improvement in obstetrical and neonatal care. The correct evaluation of postnatal growth of these babies is nowadays of primary concern, although the definitions of their optimal nutrition and postnatal growth pattern are still controversial. It is known that VLBW infants have a specific postnatal growth pattern markedly different from that of higher birthweight full-term infants. Prospective longitudinal studies are needed to trace VLBW infants growth charts for weight, length and head circumference. These charts will be a useful tool to monitor postnatal growth of VLBW infants both during hospitalisation and after discharge, up to 2 or 3 years of age. A useful tool in VLBW infants growth evaluation could also be absolute velocity charts that, allowing a better and earlier identification of growth anomalies, could permit the observation of phenomena not yet visible on distance charts. Very low birth weight (VLBW) infants' survival has greatly increased in the last few decades thanks to the improvement in obstetrical and neonatal care. These neonates represent about 1-1.5% of all live born infants in developed countries (1) and they constitute the large majority of the population in neonatal intensive care units (NICUs). For this reason, the correct evaluation of their postnatal growth is of primary concern nowadays although the definitions of optimal nutrition and postnatal growth pattern are still controversial.

    Full Text Available We conducted a retrospective case series study to evaluate the safety of fosfluconazole prophylaxis for preventing invasive fungal infection in VLBW infants with a central vascular access. Fosfluconazole was administered intravenously at a dose of 6 mg/kg everyday during which time a central venous catheter was placed. A total of 23 infants met the criteria for enrollment in our study. No cases of fungal infection were detected during the central venous catheter placement in the group. None of the infants had an elevated β-D-glucan, and all of them were still alive at discharge. Regarding the liver and renal function, no statistically significant differences were observed before and at the end of fosfluconazole prophylaxis. The results of this study demonstrate that fosfluconazole prophylaxis in preventing invasive fungal infection was well tolerated by VLBW infants. This is a first report to describe antifungal prophylaxis using fosfluconazole for VLBW infants.

    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.

    Full Text Available Background: Adequate nutrient supply is essential for optimal postnatal growth in very low birth weight (VLBW, birth weight<1,500 g infants. Early growth may influence the risk of metabolic syndrome later in life. Objective: To evaluate growth and blood metabolic markers (adiponectin, leptin, and insulin-like growth factor-1 (IGF-1 in VLBW infants participating in a randomized nutritional intervention study. Design: Fifty VLBW infants were randomized to an enhanced nutrient supply or a standard nutrient supply. Thirty-seven infants were evaluated with growth measurements until 2 years corrected age (CA. Metabolic markers were measured at birth and 5 months CA. Results: Weight gain and head growth were different in the two groups from birth to 2 years CA (weight gain: pinteraction=0.006; head growth: pinteraction=0.002. The intervention group improved their growth z-scores after birth, whereas the control group had a pronounced decline, followed by an increase and caught up with the intervention group after discharge. At 5 months CA, adiponectin concentrations were higher in the intervention group and correlated with weight gain before term (r=0.35 and nutrient supply (0.35≤r≤0.45. Leptin concentrations correlated with weight gain after term and IGF-1 concentrations with length growth before and after term and head growth after term (0.36≤r≤0.53. Conclusion: Enhanced nutrient supply improved early postnatal growth and may have prevented rapid catch-up growth later in infancy. Adiponectin concentration at 5 months CA was higher in the intervention group and correlated positively with early weight gain and nutrient supply. Early nutrition and growth may affect metabolic markers in infancy.Clinical Trial Registration (ClinicalTrials.gov no.: NCT01103219

    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 OBJECTIVE: To compare estimates of low birth weight (LBW, preterm birth, small for gestational age (SGA, and infant mortality in two birth cohorts in Brazil. METHODS: The two cohorts were performed during the 1990s, in São Luís, located in a less developed area in Northeastern Brazil, and Ribeirão Preto, situated in a more developed region in Southeastern Brazil. Data from one-third of all live births in Ribeirão Preto in 1994 were collected (2,839 single deliveries. In São Luís, systematic sampling of deliveries stratified by maternity hospital was performed from 1997 to 1998 (2,439 single deliveries. The chi-squared (for categories and trends and Student t tests were used in the statistical analyses. RESULTS: The LBW rate was lower in São Luís, thus presenting an epidemiological paradox. The preterm birth rates were similar, although expected to be higher in Ribeirão Preto because of the direct relationship between preterm birth and LBW. Dissociation between LBW and infant mortality was observed, since São Luís showed a lower LBW rate and higher infant mortality, while the opposite occurred in Ribeirão Preto. CONCLUSIONS: Higher prevalence of maternal smoking and better access to and quality of perinatal care, thereby leading to earlier medical interventions (cesarean section and induced preterm births that resulted in more low weight live births than stillbirths in Ribeirão Preto, may explain these paradoxes. The ecological dissociation observed between LBW and infant mortality indicates that the LBW rate should no longer be systematically considered as an indicator of social development.

    Full Text Available CONTEXT AND OBJECTIVE: There are no studies on birth weights among full-term infants born by means of elective cesarean section. We aimed to study this in private and public hospitals. DESIGN AND SETTING: Retrospective study at Universidade Federal do Triângulo Mineiro, Uberaba, Brazil. METHODS: Data were collected from the municipal medical birth register of Uberaba from January to December 2000. The data obtained (maternal age, type of delivery, number of prenatal care visits and birth weight, from full-term pregnancy from the university hospital (UH, which is a tertiary hospital that only attends patients within the National Health System (SUS, were compared with data from four private hospitals (PHs that attend health insurance plans and private patients. Student's t test, chi2 test and multiple logistic regression were used for statistical analysis, with the significance level set at p < 0.05. RESULTS: In the PHs, 1,100 out of 1,354 births (81.2% were by cesarean section and in the UH, 373 out of 1,332 (28%. Birth weight increased significantly in association with increasing numbers of prenatal care visits, except for cesarean section cases in PHs. Birth weights among vaginal delivery cases in PHs were greater than in the UH (p < 0.05, but this was not observed among cesarean section cases. Multiple logistic regression showed that there was greater risk of low birth weight in PHs (odds ratio: 2.33; 95% confidence interval: 1.19 to 4.55. CONCLUSION: Elective cesarean section performed in PHs may be associated with low birth weight among full-term infants.

    Full Text Available Breast milk is a major source for acquired cytomegalovirus infection especially in premature infants and acquired CMV infection occurs in infants whose mothers were seropositive for CMV. Although most of mothers of premature infants are seropositive in Turkey, acquired life-threatening breast milk acquired CMV infection was reported occasionally. Treatment of preterm with symptomatic breast milk acquired CMV infection should be done according to the severity of clinical signs. In this report, a preterm case with a diagnosis of breast milk-acquired CMV meningitis and sepsis without multiorgan failure on the 111th day of life, who did not require antiviral therapy was presented and discussed in the context of the acquired CMV literature. In preterm babies, when there is sepsis with no apparent causes, unexplained thrombocytopenia, elevated liver transaminases and direct hyperbilirubinemia acquired CMV infection should be suspected.

    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

    Twenty-two very low birth weight infants at preschool ages of 5-6 years were studied to clarify the correlation between cognitive function and MRI findings. Cognitive function was evaluated by the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Frostig developmental test of visual perception. Ventricular enlargement, assessed by the bioccipital index (B.I.) measured on MRI, was correlated to cognitive disorders. Children with periventricular high intensity areas (T{sub 2}-weighted images) extending from the posterior periventricular region to the parietal lobe tend to highly suffer from cerebral palsy and visuoperceptual impairment. These results indicate that the disorders of cognitive function in very low birth weight infants were caused by a damage of association fibers in periventricular areas which was detectable by MRI.

    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.

    Full Text Available Very low birth weight (VLBW infants is one of the most important medical problem especially in developing countries. This issue is due to its high morbidity and mortality rate. On the other hand, the long term impact of VLBW infants are poor growth and development including physical, emotional, intelectual (IQ, and disabilities, therefore it could decrease the quality of human resources and become a burden to their family. The objective of this study was to describe the characteristics and outcome among VLBW infants born in the Sanglah Hospital. This was a retrospective study. Data were collected from medical record of all infants with VLBW delivered in Sanglah Hospital from January to Desember 2009. Uncompleted infants and mother medical records were excluded from this study. Of 64 VLBW infants enrolled into the study of which 54.7%  of this subjects was male, median of weight was 1300 g, mean gestational of age was 30.9 (SD 2.28 weeks, and mean lenght of stay was 30.9 (SD 19.7 days. The survival of VLBW infants in this study was 62.5%,  mortality in the early neonatal period was 70,8%. The percentage of VLBW infants who survive was still low and the major causes mortality were HMD (50% and sepsis (41.6%. The mortality of VLBW happened mostly in early neonatal periode.

    The aim of this study was to clarify the effects of gestational age and birth weight on outcomes of the infants. Medical records of 36 infants with trisomy 18 admitted to Tokyo Women's Medical University Hospital from 1991 to 2012 were reviewed retrospectively. We compared clinical characteristics between term infants (n = 15) and preterm infants (n = 21). There were one very-low-birth-weight (VLBW) term infant (5%) and 12 VLBW preterm infants (80%). Although there were no significant differences in clinical characteristics and provided management between the two groups, none of the preterm infants achieved survival to discharge. On the other hand, 6 of 21 term infants (29%) achieved survival to discharge (P trisomy 18. In both preterm and term groups, the infants who died before 30 days commonly died of respiratory failure or apnea. Whereas, the infants who survived more than 30 days mostly died of heart failure.

    Full Text Available BACKGROUND: Low birth weight followed by accelerated weight gain during early childhood has been associated with adverse metabolic and cardiovascular outcomes later in life. The aim of this study was to examine the impact of early infant weight gain on glucose metabolism and cardiovascular risk factors in adolescence and to study if the effect differed between adolescents born small for gestational age (SGA vs. appropriate for gestational age (AGA. METHODOLOGY/PRINCIPAL FINDINGS: Data from 30 SGA and 57 AGA healthy young Danish adolescents were analysed. They had a mean age of 17.6 years and all were born at term. Data on early infant weight gain from birth to three months as well as from birth to one year were available in the majority of subjects. In adolescence, glucose metabolism was assessed by a simplified intravenous glucose tolerance test and body composition was assessed by dual-energy X-ray absorptiometry. Blood pressures as well as plasma concentrations of triglycerides and cholesterol were measured. Early infant weight gain from birth to three months was positively associated with the fasting insulin concentration, HOMA-IR, basal lipid levels and systolic blood pressure at 17 years. There was a differential effect of postnatal weight gain on HOMA-IR in AGA and SGA participants (P for interaction = 0.03. No significant associations were seen between postnatal weight gain and body composition or parameters of glucose metabolism assessed by the simplified intravenous glucose tolerance test. In subgroup analysis, all associations with early infant weight gain were absent in the AGA group, but the associations with basal insulin and HOMA-IR were still present in the SGA group. CONCLUSION: This study suggests that accelerated growth during the first three months of life may confer an increased risk of later metabolic disturbances--particularly of glucose metabolism--in individuals born SGA.

    Full Text Available Abstract Background Little is known about the growth of VLBW infants in South Africa. The aim of this study was to assess the growth of a cohort of VLBW infants in Johannesburg. Methods A secondary analysis of a prospective cohort was conducted on 139 VLBW infants (birth weight ≤1500 g admitted to Charlotte Maxeke Johannesburg Academic Hospital. Growth measurements were obtained from patient files and compared with the World Health Organization Child Growth Standards (WHO-CGS and with a previous cohort of South African VLBW infants. The sample size per analysis ranged from 11 to 81 infants. Results Comparison with the WHO-CGS showed initial poor growth followed by gradual catch up growth with mean Z scores of 0.0 at 20 months postmenstrual age for weight, -0.8 at 20 months postmenstrual age for length and 0.0 at 3 months postmenstrual age for head circumference. Growth was comparable with that of a previous cohort of South African VLBW infants in all parameters. Conclusions Initial poor growth in the study sample was followed by gradual catch up growth but with persistent deficits in length for age at 20 months postmenstrual age relative to healthy term infants.

    We report a case where a knot developed in a urinary catheter and became lodged within the urethra of a very-low-birth-weight (VLBW) preterm infant. The catheter was removed with the assistance of a urologist. We recommend using caution when placing urinary catheters in VLBW infants and question the appropriateness of feeding tubes as catheters. Recognition on radiographs of malpositioned bladder catheters is vital to the care of these patients. All staff involved in the insertion, maintenance or removal of these catheters should be suitably trained to minimize the risk of knots and related complications. (orig.)

    Low birth weight (LBW) and fetal anaemia (FA) are common in malaria endemic areas. To investigate the incidence of infectious morbidity in infants in rural Malawi in relation to birth weight and fetal anaemia, a cohort of babies was followed for a year on the basis of LBW (<2500) and FA (cord haemoglobin < 12.5 g/dl). A matched group of normal birth weight (NBW), non-anaemic (NFA) new-borns were enrolled as controls. Morbidity episodes were recorded at 4-weekly intervals and at each extra visit made to a health centre with any illness. Infants in the NBW NFA group experienced an average of 1.15 (95% C.I. 0.99, 1.31), 1.04 (0.89, 1.19), 0.92 (0.73, 1.11) episodes per year of malaria, respiratory infection and diarrhoea respectively. Corresponding values for the LBW FA group were 0.83 (0.5, 1.16), 0.82 (0.5, 1.16) and 0.76 (0.33, 1.19). FA was not associated with a higher incidence of morbidity, but was significantly associated with a shorter time to first illness episode (p = 0.014). LBW was not a significant risk factor for higher morbidity incidence. LBW and FA were not significant risk factors for incidence of illness episodes in infants.

    With growing evidence of the adverse health effects of air pollution--especially fine particulates--investigators must concentrate on the fetus, neonate, and infant as potentially vulnerable groups. Cokeworks are a major source of smoke and sulfur dioxide. In the current study, the authors investigated whether populations residing near cokeworks had a higher risk of adverse perinatal and infant outcomes. Zones of 7.5-km radius around 22 cokeworks in Great Britain were studied, within which the authors assumed that exposure declined from highest levels within 2 km to background levels. Routinely recorded birth and death data for Great Britain during the period 1981--1992 were analyzed. Each individual record had a postcode that referred to a small geographical area of typically 15--17 addresses. The authors calculated expected numbers on the basis of regional rates, stratified by year, sex, and a small-area socio-economic deprivation score. For all cokeworks combined, the observed/expected ratio within 2 km of cokeworks was 1.00 for low-birth-weight infants; 0.94 for still births; 0.95 for infant mortality; 0.86 for neonatal mortality; 1.10 for postneonatal mortality; 0.79 for respiratory postneonatal mortality; and 1.07 for postneonatal Sudden Infant Death Syndrome. Respiratory postneonatal mortality was low throughout the entire 0--7.5-km study area. There was no statistically significant decline in risk with distance from cokeworks for any of the outcomes studied. The authors concluded that there was no evidence of an increased risk of low birth weight, stillbirths, and/or neonatal mortality near cokeworks, and there was no strong evidence for any association between residence near cokeworks and postneonatal mortality. One must remember, however, the limited statistical power of the study to detect small risks.

    Full Text Available Low birth weight (LBW infant is susceptible to health problems since the infant born, during in the hospital and continue after discharge. The purpose of this study was to identify the influence of family empowerment on the health status of LBW infant. Action research using qualitative and quantitative method was used in this study. Qualitative approach was used to identify the experience of mothers of LBW infants as a data based for intervention development, and quantitative approach was used to evaluate the influence of family empowerment program on the health status of LBW infants. There were 7 participants, 20 mothers and their infants in the intervention group and 27 in the control group involved in this study. The study showed that family empowerment was effective in improving the immunization status and follow- up care attendance, reducing the frequency of acute care visits, increasing mothers' knowledge and skill in providing care. In conclusion, mothers need information on providing a proper care for LBW, and family empowerment can significantly improve maternal knowledge and health status of LBW infants.

    Advances in neonatal intensive care have not yet reduced the high incidence of neurodevelopmental disability among very-low-birth-weight (VLBW) infants. As neurological deficits are related to white-matter injury, early detection is important. Diffusion tensor imaging (DTI) could be an excellent tool for assessment of white-matter injury. To provide DTI fractional anisotropy (FA) reference values for white-matter tracts of VLBW infants for clinical use. We retrospectively analysed DTI images of 28 VLBW infants (26-32 weeks gestational age) without evidence of white-matter abnormalities on conventional MRI sequences, and normal developmental outcome (assessed at age 1-3 years). For DTI an echoplanar sequence with diffusion gradient (b = 1,000 s/mm{sup 2}) applied in 25 non-collinear directions was used. We measured FA and apparent diffusion coefficient (ADC) of different white-matter tracts in the first 4 days of life. A statistically significant correlation was found between gestational age and FA of the posterior limb of the internal capsule in VLBW infants (r = 0.495, P<0.01). Values of FA and ADC were measured in white-matter tracts of VLBW infants. FA of the pyramidal tracts measured in the first few days after birth is related to gestational age. (orig.)

    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.

    Full Text Available Objective: the research objective was to characterize preterm infants with birth weight under 1500 g, and to identify the incidence of late-onset neonatal sepsis among this population. Methods: a prospective cohort study with a sample of 30 preterm newborns that weighed under 1500 g and were hospitalized in the NICU of the university hospital. Data were collected from January to December 2013 using a structured instrument. Results: of the 30 neonates included in the study, 14 developed late-onset neonatal sepsis with a prevalence of coagulase-negative staphylococci. Conclusions: the incidence of late-onset neonatal sepsis indicates a vulnerability in preterm infants due to immunological immaturity. These results reveal that knowledge of the profile of newborn infants admitted to the NICU and the risk factors to which they are exposed are central to the planning of nursing care for these patients. Future studies should address strategies for preventing nosocomial infection.

    Despite improvements in service delivery and patient management, low birth weight among infants has been a persistent challenge in South Africa. The study aimed to explore the relationship between depression before pregnancy and the low birth weight (LBW) of infants in post-apartheid South Africa. This study utilized data from Waves 1 and 2 of the South African National Income Dynamics Study, the main outcome being a dichotomous measure of child LBW (<2500 g) drawn from the Wave 2 child questionnaire. Depressive symptoms of non-pregnant women was the main predictor drawn from the Wave 1 adult questionnaire. Depressive symptoms were screened using the 10-item four-point Likert version of the Center for Epidemiologic Studies Depression Scale (CES-D) instrument. A total score of 10 or greater on the CES-D indicates a positive screen for depressive symptoms. An adjusted logistic regression model was used to examine the relationship between women's depression before pregnancy and infant LBW. A sample size of 651 women in Wave 1 was linked to 672 newborns in Wave 2. The results of the adjusted logistic regression model indicated depressive symptoms (CES-D ≥ 10) prior to pregnancy were associated with infant LBW (adjusted OR 2.84, 95 % CI 1.08-7.46). Another significant covariate in the model was multiple childbirths. Our finding indicates that women's depressive symptoms prior to pregnancy are associated with the low birth weight of newborns and suggests that this association may not be limited to depression present during the ante-natal phase.

    Full Text Available For many years endotracheal intubation and mechanical ventilation have been the standard of care for very low birth weight infants but, in the last decade, nasal continuous positive airway pressure (nCPAP has been described in many studies as an option for the treatment of preterm infants with respiratory distress syndrome. In fact, recent studies have shown that early nCPAP is not associated with higher rates of morbidity and mortality and does not imply more days of ventilation support when compared to traditional ventilation techniques. The authors conducted a study to compare the outcomes (in terms of mortality, morbidity and need for medical support of very low birth weight infants treated with nCPAP or endotracheal intubation and mechanical ventilation. One hundred and four newborns were enrolled in this study, 44 (42.3% were treated with nCPAP and 60 (57.7% with endotracheal intubation followed by mechanical ventilation. A subgroup analysis of newborns with gestational age between 28 and 31 weeks was also performed. It included 57 newborns with similar demographic characteristics, 29 (50.9% treated with nCPAP and 28 (49.1% with endotracheal intubation followed by mechanical ventilation. No statistically significant differences were found in the frequency of death or bronchopulmonary dysplasia. Statistically significant differences were found in the prevalence of hyaline membrane disease (p = 0.033 and surfactant administration (p = 0.021 with lower rates in the nCPAP group. No other differences were found in the prevalence of other morbidities or in the need for medical support after birth. These results suggests that nCPAP might be chosen as primary ventilatory support choice in very low birth weight preterm, when there are no contraindications to its use.

    Background. Low birth weight (LBW), an outcome of maternal undernutrition, is a major public health concern in Bangladesh where the problem is most prominent. Women's decision-making autonomy is likely an important factor influencing maternal and child health outcomes. The aim of the study was to assess the effect of women's decision-making autonomy on infant's birth weight (BW). Methods. The study included data of 2175 enrolled women (14-45 years of age) from the Maternal and Infant Nutritional Intervention in Matlab (MINIMat-study) in Bangladesh. Pearson's chi-square test, analysis of covariance (ANCOVA), and logistic regression analysis were applied at the collected data. Results. Women with lowest decision-making autonomy were significantly more likely to have a low birth weight (LBW) child, after controlling for maternal age, education (woman's and her husband's), socioeconomic status (SES) (odds ratio (OR) = 1.4; 95% confidence interval (CI) 1.0, 1.8). BW was decreased significantly among women with lowest decision making autonomy after adjusting for all confounders. Conclusion. Women's decision-making autonomy has an independent effect on BW and LBW outcome. In addition, there is a need for further exploration to identify sociocultural attributes and gender related determinants of women decision-making autonomy in this study setting.

    Renal calcifications have been described in very low birth weight (VLBW) infants, and diuretic drug-associated hypercalciuria is believed to play a role in the pathogenesis of this lesion. Hyperoxaluria is an important cause of renal stone formation in children and adults. Because parenteral nutrition solutions contain the oxalate precursors ascorbate and glycine, the relationship between total parenteral nutrition administration and oxalate excretion in VLBW infants was examined. Administration of approximately 0.5 g of total parenteral nutrition protein per kilogram per day to VLBW infants was associated with an increased urinary oxalate concentration and an increased urinary oxalate to creatinine ratio, when compared with VLBW infants receiving a glucose and electrolyte solution. A further increase in urinary oxalate concentration and oxalate to creatinine ratio was noted when total parenteral nutrition protein was increased to approximately 1.5 g of protein per kilogram per day. In VLBW infants who receive total parenteral nutrition, elevated urinary oxalate concentrations may develop and may be a factor in the pathogenesis of nephrocalcinosis in these infants.

    Full Text Available OBJECTIVES: to evaluate infant mortality in very low birth weight newborns from a public hospital in Rio de Janeiro, Brazil (2002-2006. METHODS: a retrospective cohort study was performed using the probabilistic linkage method to identify infant mortality. Mortality proportions were calculated according to birth weight intervals and period of death. The Kaplan-Meier method was used to estimate overall cumulative survival probability. The association between maternal schooling and survival of very low birth weight infants was evaluated by means of Cox proportional hazard models adjusted for: prenatal care, birth weight, and gestational age. RESULTS: the study included 782 very low birth weight newborns. Of these, (28.6% died before one year of age. Neonatal mortality was 19.5%, and earlyneonatal mortality was 14.9%. Mortality was highest in the lowest weight group (71.6%. Newborns whose mothers had less than four years of schooling had 2.5 times higher risk of death than those whose mothers had eight years of schooling or more, even after adjusting for intermediate factors. CONCLUSIONS: the results showed higher mortality among very low birth weight infants. Low schooling was an independent predictor of infant death in this low-income population sample.

    Full Text Available OBJECTIVE: To develop a homologous human milk supplement for very low-birth weight infant feeding, using an original and simplified methodology, to know the nutritional composition of human milk fortified with this supplement and to evaluate its suitability for feeding these infants. METHODS: For the production and analysis of human milk with the homologous additive, 25 human milk samples of 45mL underwent a lactose removal process, lyophilization and then were diluted in 50mL of human milk. Measurements of lactose, proteins, lipids, energy, sodium, potassium, calcium, phosphorus and osmolality were performed. RESULTS: The composition of the supplemented milk was: lactose 9.22±1.00g/dL; proteins 2.20±0.36g/dL; lipids 2.91±0.57g/dL; calories 71.93±8.69kcal/dL; osmolality 389.6±32.4mOsmol/kgH2O; sodium 2.04±0.45mEq/dL; potassium 1.42±0.15mEq/dL; calcium 43.44±2.98mg/dL; and phosphorus 23.69±1.24mg/dL. CONCLUSIONS: According to the nutritional contents analyzed, except for calcium and phosphorus, human milk with the proposed supplement can meet the nutritional needs of the very low-birth weight preterm infant.

    Full Text Available BACKGROUND: The consequences of maternal HIV infection for fetal growth are controversial. Here, we estimated the frequency of small for gestational age and gender (SGAG among neonates born to HIV-infected or uninfected mothers and assessed the contribution, if any, of maternal HIV to the risk of SGAG. METHODS: The data used were obtained from the ANRS-Pediacam cohort in Cameroon. Pairs of newborns, one to a HIV-infected mother and the other to an uninfected mother, were identified during the first week of life, and matched on gender and recruitment site from 2007-2010. SGAG was defined in line with international recommendations as a birth weight Z-score adjusted for gestational age at delivery and gender more than two standard deviations below the mean (-2SD. Considering the matched design, logistic regression modeling was adjusted on site and gender to explore the effect of perinatal HIV exposure on SGAG. RESULTS: Among the 4104 mother-infant pairs originally enrolled, no data on birth weight and/or gestational age were available for 108; also, 259 were twins and were excluded. Of the remaining 3737 mother-infant pairs, the frequency of SGAG was 5.3% (95%CI: 4.6-6.0, and was significantly higher among HIV-infected infants (22.4% vs. 6.3%; p<.001 and lower among HIV-unexposed uninfected infants (3.5% vs. 6.3%; p<.001 than among HIV-exposed uninfected infants. Similarly, SGAG was significantly more frequent among HIV-infected infants (aOR: 4.1; 2.0-8.1 and less frequent among HIV-unexposed uninfected infants (aOR: 0.5; 0.4-0.8 than among HIV-exposed uninfected infants. Primiparity (aOR: 1.9; 1.3-2.7 and the presence of any disease during pregnancy (aOR: 1.4; 1.0-2.0 were identified as other contributors to SGAG. CONCLUSION: Maternal HIV infection was independently associated with SGAG for HIV-exposed uninfected infants. This provides further evidence of the need for adapted monitoring of pregnancy in HIV-infected women, especially if they are

    Full Text Available Objective: Improved survival of preterm infants, beneficial effects of trophic feeding and limited data on timing management of enteral feeding for very low birth weight preterm infants requires more researches to determine the exact starting time and increased volumes. This study aims to compare early (72h trophic feeding with respect to important neonatal outcomes.Methods: In a cohort study from September 2007 to October 2008, a total of 170 preterm infants (1000-1500gram, 26-31 weeks consisting of 125 who received trophic feeding enterally within the first 48 hours of birth(early group and 45 fed enterally after 72 h0urs (late group, without major congenital birth defects and severe asphyxia entered the study. Bolus feeding was started in both groups at 1-2 cc/kg every 4-6 hours of human milk or preterm infant formula and was advanced 1-2 cc/kg/day if tolerated along with parenteralnutrition. Feeding intolerance, possibility of necrotizing entrocolitis (NEC, episodes of sepsis, body weight,length of NICU stay, and duration of parenteral nutrition were assessed serially.Findings: There were no statistically significant differences in the clinical and maternal characteristics ofinfants in the two groups. The time to gain birth weight (13.75±5.21 vs 20.53±6.31 (P<0.001, duration of parenteral nutrition (9.26±4.572 days vs 14.11±6.415 days (P<0.001, hospital stay (12.14±8.612 vs 21.11±1.156 (P<0.001 were significantly shorter in early compared to late feeding group; none of the twogroups experienced a high incidence of late onset sepsis (P=0.73. There was 1 case of confirmed NEC in every group.Conclusion: The benefits of early trophic feeding shown by this study strongly support its use for the preterm infants without adding to complications.

    Preterm low-birth-weight infants remain difficult to manage based on adequate laboratory tests. The aim of this study was to establish blood reference intervals (RIs) in those newborns who were admitted to and survived in the neonatal intensive care unit (NICU). A multicenter prospective study was conducted among all infants admitted to 11 affiliated NICUs from 2010 to 2013. The clinical information and laboratory data were registered in a network database designed for this study. The RIs for 26 items were derived using the parametric method after applying the latent abnormal values exclusion method. The influence of birth weight (BW) and gestational age (GA) on the test results was expressed in terms of the standard deviation ratio (SDR), as SDRBW and SDRGA, respectively. A total of 3189 infants were admitted during the study period; 246 were excluded due to a lack of blood sampling data, and 234 were excluded for chromosomal abnormalities (n = 108), congenital anomalies requiring treatment with surgical procedures (n = 76), and death or transfer to another hospital (n = 50). As a result, 2709 infants were enrolled in this study. Both the SDRGA and SDRBW were above 0.4 in the test results for total protein (TP), albumin (ALB), alanine aminotransferase (ALT), and red blood cells (RBC); their values increased in proportion to the BW and GA. We derived 26 blood RIs for infants who were admitted to NICUs. These RIs should help in the performance of proper clinical assessments and research in the field of perinatal-neonatal medicine.

    Background In very-low-birth-weight infants IGF-I plays an important role in postnatal growth restriction and is probably also involved in growth restriction in childhood. We compared IGF-I and its relation to growth in early childhood in very-low-birth-weight infants and term appropriate for gestational age born infants. Methods We included 41 very-low-birth-weight and 64 term infants. Anthropometry was performed at all visits to the outpatient clinic. IGF-I and insulin were measured in blood samples taken at 6 months and 2 years corrected age (very-low-birth-weight children) and at 3 months, 1 and 2 years (term children). Results Over the first 2 years of life growth parameters are lower in very-low-birth-weight children compared to term children, but the difference in length decreases significantly. During the first 2 years of life IGF-I is higher in very-low-birth-weight children compared to term children. In both groups there is a significant relationship between IGF-I and (change in) length and weight over the first 2 years of life and between insulin and change in total body fat. Conclusions Considering the relation of IGF-I to growth and the decrease in difference in length, higher IGF-I levels in very-low-birth-weight infants in early childhood probably have an important role in catch-up growth in length.

  8. Beyond bacteria: a study of the enteric microbial consortium in extremely low birth weight infants.

    Directory of Open Access Journals (Sweden)

    Mariam Susan LaTuga

    Full Text Available Extremely low birth weight (ELBW infants have high morbidity and mortality, frequently due to invasive infections from bacteria, fungi, and viruses. The microbial communities present in the gastrointestinal tracts of preterm infants may serve as a reservoir for invasive organisms and remain poorly characterized. We used deep pyrosequencing to examine the gut-associated microbiome of 11 ELBW infants in the first postnatal month, with a first time determination of the eukaryote microbiota such as fungi and nematodes, including bacteria and viruses that have not been previously described. Among the fungi observed, Candida sp. and Clavispora sp. dominated the sequences, but a range of environmental molds were also observed. Surprisingly, seventy-one percent of the infant fecal samples tested contained ribosomal sequences corresponding to the parasitic organism Trichinella. Ribosomal DNA sequences for the roundworm symbiont Xenorhabdus accompanied these sequences in the infant with the greatest proportion of Trichinella sequences. When examining ribosomal DNA sequences in aggregate, Enterobacteriales, Pseudomonas, Staphylococcus, and Enterococcus were the most abundant bacterial taxa in a low diversity bacterial community (mean Shannon-Weaver Index of 1.02 ± 0.69, with relatively little change within individual infants through time. To supplement the ribosomal sequence data, shotgun sequencing was performed on DNA from multiple displacement amplification (MDA of total fecal genomic DNA from two infants. In addition to the organisms mentioned previously, the metagenome also revealed sequences for gram positive and gram negative bacteriophages, as well as human adenovirus C. Together, these data reveal surprising eukaryotic and viral microbial diversity in ELBW enteric microbiota dominated bytypes of bacteria known to cause invasive disease in these infants.

    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.

    Objectives: To determine (1) whether prescribed and delivered energy and protein intakes during the first two weeks of life met Ziegler's estimated requirements for Very Low Birth Weight (VLBW) infants, (2) if actual energy during the first week of life correlated with time to regain birth weight and reach full enteral nutrition (EN) defined as 100 kcal/kg/day, (3) if growth velocity from time to reach full EN to 36 weeks' postmenstrual age (PMA) met Ziegler's estimated fetal growth velocity (16 g/kg/day), and (4) growth outcomes at 36 weeks' PMA. Study design: Observational study of feeding, early nutrition and early growth of 40 VLBW infants protein (89% [3.1 g/kg/day]) were significantly less than theoretical estimated requirements. Delivered intakes were 15% less than prescribed because of numerous interruptions in delivery and medical complications. During the second week, the delivered intakes of energy (90% [86 kcal/kg/day]) and protein (102% [3.5 g/kg/day]) improved although the differences between prescribed and delivered were consistently 15%. Energy but not protein intake during the first week was significantly related to time to reach full EN. Neither energy nor protein intake significantly correlated with days to return to birth weight. The average growth velocity from the age that full EN was attained to 36 weeks' PMA (15 g/kg/day) was significantly less than the theoretical estimated fetal growth velocity (16 g/kg/day) (pintakes were consistently less than 15% of the prescribed intakes. Growth velocity between the age when full EN was achieved and 36 weeks' PMA was 6.7% lower than Ziegler's estimate. One-third to one-half of the infants have EUGR at 36 weeks' PMA.

    Heated water pads were placed underneath very-low-birth-weight preterm infants receiving care under overhead radiant warmers with plastic heat shields to evaluate the effects on their thermal environments. The electrical input (watts) to the overhead warmer was monitored and temperatures at various locations in the environment and on the infants were recorded. The electrical input to the radiant warmers decreased significantly (P = 0.0015) with the introduction of the heated water pads. Several of the temperatures recorded during the study also showed significant changes, including increased abdominal skin temperatures in these prone infants (P = 0.007) and decreased back-to-abdomen skin temperature gradients (P = 0.007). Less marked changes included higher mattress or pad temperatures (P = 0.019), lower ambient air temperatures within the plastic heat shields (P = 0.022), and increased infant foot temperatures (P = 0.036). We believe that conduction has a significant influence on the thermal environment of the VLBW infant cared for under an overhead radiant warmer and that the use of a heated water pad can markedly alter heat transfer. The impact of conduction appears to have been previously underestimated.

    Full Text Available Background: Kangaroo Mother Care (KMC is dened as skin-to-skin contact between a mother and her newborn baby derived from practical similarities to marsupial care giving, proximately exclusive breastfeeding and early discharge from hospital. This concept was proposed as an alternative to conventional methods of care for low birth weight (LBW infants, and in replication to quandaries of earnest overcrowding in Neonatal Intensive Care Units (NICUs. KMC essentially utilizes the mother as a natural incubator Aim and Objectives: The aim was to assess the feasibility, acceptability and the effectiveness of KMC in LBW infants. It avoids agitation routinely experienced in busy ward. Material and Methods: A pilot open-labeled quasi-randomised clinical trial was conducted in Level III NICU of a teaching institution. 60 newborn infants <2500 g, meeting inclusion criteria were alternatively randomised into two groups: Kangaroo Mother Care (KMC and Conventional Methods of Care (CMC. Kangaroo mother care was practiced with minimum total period of eight hours a day intermittently for the intervention group while the controls remained in incubators or cots. Weight, head circumference, length, morbidity episodes, hospital stay, feeding patterns were monitored for all infants till postmenstrual age of 42 weeks in preterm babies or till a weight of 2500 g is achieved in term SGA babies. Results: The pilot study conrmed that trial processes were efcient, the intervention was acceptable (to mothers and nurses and that the outcome measures were appropriate; KMC babies achieved signicantly better growth at the end of the study (For preterm babies, weight, length and head circumference gain were signicantly higher in the KMC group (weight 19.28±2.9g/day, length 0.99±0.56cm/week and head circumference 0.72±0.07 cm/week than in the CMC group (P <0.001.

    BACKGROUND: Randomised trials have shown that early Bacille Calmette-Guérin (BCG) vaccine reduces overall neonatal and infant mortality. However, no study has examined how BCG affects growth. We investigated the effect on infant growth of early BCG vaccine given to low-birth-weight (LBW) infants....... METHODS: Two-thousand three hundred forty-three LBW infants were randomly allocated 1:1 to "early BCG" (intervention group) or "late BCG" (current practice).

    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.

This review assessed if probiotics, prebiotics led to improved growth and clinical outcomes in formula fed preterm infants. Methods Cochrane methodology was followed using randomized controlled trials (RCTs which compared preterm formula containing probiotic(s or prebiotic(s to conventional preterm formula in preterm infants. The mean difference (MD and corresponding 95% confidence intervals (CI were reported for continuous outcomes, risk ratio (RR and corresponding 95% CI for dichotomous outcomes. Heterogeneity was assessed by visual inspection of forest plots and a chi2 test. An I2 test assessed inconsistencies across studies. I2> 50% represented substantial heterogeneity.

    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.

    Many intervention studies in preterm infants aim to improve neurodevelopmental outcome, but short-term proxy outcome measurements are lacking. Cortical plate and subplate development could be such a marker. Our aim was to provide normal DTI reference values for the cortical plate and subplate of preterm infants. As part of an ongoing study we analysed diffusion tensor imaging (DTI) images of 19 preterm infants without evidence of injury on conventional MRI, with normal outcome (Bayley-II assessed at age 2), and scanned in the first 4 days of life. Fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values in the frontal and temporal subplate and cortical plate were measured in single and multiple voxel regions of interest (ROI) placed on predefined regions. Using single-voxel ROIs, statistically significant inverse correlation was found between gestational age (GA) and FA of the frontal (r = -0.5938, P = 0.0058) and temporal (r = -0.4912, P = 0.0327) cortical plate. ADC values had a significant positive correlation with GA in the frontal (r = 0.5427, P = 0.0164) and temporal (r = 0.5540, P = 0.0138) subplate. Diffusion tensor imaging allows in vivo exploration of the evolving cortical plate and subplate. We provide FA and ADC values of the subplate and cortical plate in very-low-birth-weight (VLBW) infants with normal developmental outcome that can be used as reference values. (orig.)

    Full Text Available Background Bloodstream infection (BSI is one of the significant causes of morbidity and mortality encountered in a neonatal intensive care unit (NICU, especially in developing countries. Despite the implementation of infection control practices, such as strict hand hygiene, the BSI rate in our hospital is still high. The use of a closed catheter access system to reduce BSI related to intravascular catheter has hitherto never been evaluated in our hospital. Objective To determine the effects of closed catheter access system implementation in reducing the BSI rate in preterm neonates with low birth weight.Methods Randomized clinical trial was conducted on 60 low birth weight preterm infants hospitalized in the neonatal unit at Cipto Mangunkusumo Hospital, Jakarta, Indonesia from June to September, 2013. Randomized subjects either received a closed or non-closed catheter access system. Subjects were monitored for 2 weeks for the development of BSI based on clinical signs, abnormal infection parameters, and blood culture. Results Closed catheter access system implementation gave a protective effect towards the occurrence of culture-proven BSI (relative risk 0.095, 95% CI 0.011 to 0.85, p=0.026. Risk of culture-proven BSI in the control group was 10.545 (95% CI 1.227 to 90.662, p=0.026. BSI occurred in 75% of neonates without risk factors of infection in the control group compared to none in the study group.Conclusions The use of a closed catheter access system reduced the BSI in low birth weight preterm infants. Choosing the right device design, proper disinfection of device and appropriate frequency of connector change should be done simultaneously.

    To test the hypothesis that increased hypoxic ventilatory responsiveness (HVR) raised maternal ventilation and arterial oxygenation during high-altitude pregnancy and related to the birth weight of the offspring, we studied 21 residents of Cerro de Pasco, Peru (4,300 m), while eight of them were 36 +/- 0 wk pregnant and 15 of them 13 +/- 0 wk postpartum. HVR was low in the nonpregnant women (mean +/- SE shape parameter A = 23 +/- 8) but increased nearly fourfold with pregnancy (A = 87 +/- 17). The increase in HVR appeared to account for the 25% rise in resting ventilation with pregnancy (delta VE observed = 2.4 +/- 0.7 l/min BTPS vs. delta VE predicted from delta HVR = 2.6 +/- 1.7 l/min BTPS, P = NS). Hyperoxia decreased ventilation in the pregnant women (P less than 0.01) to levels similar to those measured when nonpregnant. The increased ventilation of pregnancy raised arterial O2 saturation (SaO2) from 83 +/- 1 to 87 +/- 0%, and SaO2 was correlated positively with HVR in the pregnant women. The rise in SaO2 compensated for a 0.9 g/100 ml decrease in hemoglobin concentration to preserve arterial O2 content at levels present when nonpregnant. Cardiac output in the 36th wk of pregnancy did not differ significantly from values measured postpartum. The increase in HVR correlated positively with infant birth weight. An increase in HVR may be an important contributor to increased maternal ventilation with pregnancy and infant birth weight at high altitude.

  1. Catch up growth in low birth weight infants: striking a healthy balance.

    Catch-up growth in the first few months of life is seen almost ubiquitously in infants born small for their gestational age and conventionally considered highly desirable as it erases the growth deficit. However, recently such growth has been linked to an increased risk of later adiposity, insulin resistance and cardiovascular disease in both low income and high-income countries. In India, a third of all babies are born with a low birth weight, but the optimal growth pattern for such infants is uncertain. As a response to the high rates of infectious morbidities, undernutrition and stunting in children, the current policy is to promote rapid growth in infancy. However, with socio-economic transition and urbanization making the Indian environment more obesogenic, and the increasing prevalence of type 2 diabetes and cardiovascular disease, affecting progressively younger population, the long term adverse programming effect of fast/excessive weight gain in infancy on later body composition and metabolism may outweigh short-term benefits. This review discusses the above issues focusing on the need to strike a healthy balance between the risks and benefits of catch-up growth in Indian infants.

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

    We investigated the prevalence of developmental disorders in very low birth weight infants, their risk factors during the neonatal period, and the correlation between their neurological symptoms and their MRI findings. Seventy-three infants, who were followed up for more than 5 years in the developmental clinic, were enrolled. The developmental disorders included 6 patients with cerebral palsy (CP) and 6 patients with mental retardation (MR). The types of CP were as follows: spastic diplegia (3), spastic quadriplegia (2), athetotic quadriplegia (1). Intraventricular hemorrhage (IVH) and mechanical ventilation (MV) were significant risk factors for CP and MR and retinopathy was also a significant risk factor for MR. Periventricular areas of bright signal intensity on T2 (TR 2000 msec/TE 120 mse) weighted images, compatible with old, small white matter infarcts, gliosis or demyelination, were observed in only three of the seven patients. We measured the width of anterior horns, the maximum diameter of cerebrum, and the minimum thickness of white matter in occipital lobe on T1 (TR 500 msec/TE 20 msec) weighted transaxial images in eight patients (five patients with CP, three patients with MR). The maximum diameters of cerebrums and the minimum thickness of white matters were significantly smaller in patients with CP or MR than those in controls, respectively. The DQ of patients significantly correlated with the maximum diameters of cerebrums and the minimum thickness of white matters in left occipital lobe significantly correlated with DQ. (author).

    Full Text Available Abstract Background Recent reports have documented a leveling-off of survival rates in preterm infants through the 1990's. The objective of this study was to determine temporal changes in illness severity in very low birth weight (VLBW infants in relationship to the outcomes of death and/or severe IVH. Methods Cohort study of 1414 VLBW infants cared for in a single level III neonatal intensive care unit in Delaware from 1993–2002. Infants were divided into consecutive 3-year cohorts. Illness severity was measured by two objective methods: the Score for Neonatal Acute Physiology (SNAP, based on data from the 1st day of life, and total thyroxine (T4, measured on the 5th day of life. Death before hospital discharge and severe intraventricular hemorrhage (IVH were investigated in the study sample in relation to illness severity. The fetal death rate was also investigated. Statistical analyses included both univariate and multivariate analysis. Results Illness severity, as measured by SNAP and T4, increased steadily over the 9-year study period with an associated increase in severe IVH and the combined outcome of death and/or severe IVH. During the final 3 years of the study, the observed increase in illness severity accounted for 86% (95% CI 57–116% of the variability in the increase in death and/or severe IVH. The fetal death rate dropped from 7.8/1000 (1993–1996 to 5.3/1000 (1999–2002, p = .01 over the course of the study. Conclusion These data demonstrate a progressive increase in illness in VLBW infants over time, associated with an increase in death and/or severe IVH. We speculate that the observed decrease in fetal death, and the increase in neonatal illness, mortality and/or severe IVH over time represent a shift of severely compromised patients that now survive the fetal time period and are presented for care in the neonatal unit.

    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.

    Several Canadian professional organizations recently recommended that the growth of preterm infants be monitored using the World Health Organization Growth Standards (WHO-GS) after hospital discharge. The WHO-GS are a prescriptive set of growth charts that describe how term infants should grow under ideal environmental conditions. Whether preterm infants following this pattern of growth have better outcomes than infants that do not has yet to be evaluated. Our aim was to determine whether the pattern of growth of very low birth weight (VLBW) infants during the first 2 years, assessed using the WHO-GS or the traditional Centers for Disease Control and Prevention reference growth charts (CDC-RGC), is associated with neurodevelopment. Pattern of weight, length, and head circumference gain of appropriate-for-gestation VLBW preterm infants (n = 289) from birth to 18-24 months corrected age was classified, using the WHO-GS and CDC-RGC, as sustained (change in Z-score ≤1 SD), decelerated (decline >1 SD), or accelerated (incline >1 SD). Development was assessed using the Bayley Scales of Infant and Toddler Development (BSID)-III at 18-24 months corrected age. Using the WHO-GS, children with a decelerated pattern of weight gain had lower cognitive (10 points), language (6 points), and motor (4 points) scores than infants with sustained weight gain (p neurodevelopment scores on the BSID-III than a pattern of sustained growth.

    Full Text Available Background: One of the most common methods of identifying mortality risk is the Clinical Risk Index for Babies scoring system (CRIB- II. The aim of this study was assessing the value of CRIB- II in predicting mortality risk in preterm and low birth weight infants in East Azerbaijan- Iran. Materials and Methods: This prospective cohort study was carried out in 2013-2014 during 6 months in NICUs of Alzahra, Taleqani and Children hospitals of Tabriz-Iran. All infants ≤ 32 weeks’ gestational age or ≤ 1500gr birth weight were included in the study using consecutive method. After calculating CRIB- II score, the infants were followed up at 3 months of age and their outcome was determined. The data was analyzed using SPSS-13, t- test, receiver operating characteristics (ROC and area under curve (AUC and relative risk (RR. Results: Of total 215 infants, 64 infants (29.7% died in the hospital and one infant (0.4% died after discharging from the hospital. 150 (68.8% infants, were alive at 3 months age follow up. The mean of CRIB- II score in the group of dead infants was higher and statistically significant compared to the group of alive infants (P

    Background: To compare neonatal mortality and neurodevelopmental outcomes at two years of age in very low birth weight infants (≤1500 g) born by cesarean with those by vaginal delivery. Methods: In this retrospective, case-control study, we evaluated neonatal mortality, medical conditions and neurodevelopmental outcomes at two years of corrected age in 710 very low birth weight (VLBW) infants born between January 2005 and December 2010. Of the 710 infants, 351 were born by the cesarean and 359/710 by vaginal route. Results: There were no significant differences in neonatal mortality between the cesarean delivery group and vaginal delivery group [56/351 (15.9%) vs. 71/359 (19.8%), P=0.20]. VLBW infants delivered by the cesarean procedure had a higher incidence of respiratory distress syndrome than those born by the vaginal route [221/351 (63.0%) vs. 178/359 (49.6%), P Conclusions: In neither neurodevelopment nor neonatal mortality did cesarean birth offered significant advantages to VLBW infants. Moreover, the operation might be associated with an increased risk of respiratory distress syndrome for VLBW infants. The mode of delivery of VLBW infants should be largely based on obstetric indications and maternal considerations rather than perceived better outcomes for the neonate.

    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

    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.

    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.

    Neonatal sepsis remains one of the most important causes of death and co-morbidity in very-low-birth-weight (VLBW) infants. The aim of this study was to determine the current incidences of early-onset sepsis (EOS) and late-onset sepsis (LOS), the distribution of pathogens, and the impact of infection on co-morbidities in VLBW infants. We analyzed the data including sepsis episode from 2,386 VLBW infants enrolled in Korean Neonatal Network from January 2013 to June 2014. We defined EOS as a positive blood culture occurring between birth and 7 days of life and LOS after 7 days of life. Sepsis was found in 21.1% of VLBW infants. The risk of sepsis was inversely related to birth weight and gestational age. EOS was found in only 3.6% of VLBW infants, however the mortality rate was as high as 34.1%. EOS was associated with the increased odds for bronchopulmonary dysplasia and intraventricular hemorrhage. The vast majority of EOS was caused by Gram-positive organisms, particularly coagulase-negative staphylococci (30.6%). LOS developed in 19.4% of VLBW infants with a 16.1% mortality rate. Pathogens in LOS were dominated by coagulase-negative staphylococci (38.3%). Twenty-five percent and fifty percent of first LOS episode occurred after 12 days and 20 days from birth, respectively. Younger and smaller VLBW infants showed the earlier occurrence day for the 25% of first LOS episode. This study provides a recent nationwide epidemiology of sepsis in VLBW infants in Korea. Based on this study, successful strategies to reduce infections would improve survival and reduce morbidity.

    Fluorodeoxyglucose is the most commonly used radiopharmaceutical in Positron Emission Tomography, with applications in neurology, cardiology, and oncology. Despite its routine use worldwide, the radiation absorbed dose estimates from FDG have been based primarily on data obtained from two dogs studied in 1977 and 11 adults (most likely males) studied in 1982. In addition, the dose estimates calculated for FDG have been centered on the adult male, with little or no mention of variations in the dose estimates due to sex, age, height, weight, nationality, diet, or pathological condition. Through an extensive investigation into the Medical Internal Radiation Dose schema for calculating absorbed doses, I have developed a simple patient-specific equation; this equation incorporates the parameters necessary for alterations to the mathematical values of the human model to produce an estimate more representative of the individual under consideration. I have used this method to determine the range of absorbed doses to FDG from the collection of a large quantity of biological data obtained in adult males, adult females, and very low birth weight infants. Therefore, a more accurate quantification of the dose to humans from FDG has been completed. My results show that per unit administered activity, the absorbed dose from FDG is higher for infants compared to adults, and the dose for adult women is higher than for adult men. Given an injected activity of approximately 3.7 MBq kg-1, the doses for adult men, adult women, and full-term newborns would be on the order of 5.5, 7.1, and 2.8 mSv, respectively. These absorbed doses are comparable to the doses received from other nuclear medicine procedures.

    In a group of 10 low birth weight infants we measured skin temperature using infrared thermography and laser Doppler flow in central and peripheral regions of the body. After elevation of incubator humidity from 40 to 80% skin temperature of the foot rose significantly (p less than 0.01). At the same time there was a significant increase (p less than 0.05) of laser Doppler flow. Temperature and laser Doppler flow in the area of the abdomen did not show significant changes. Low birth weight infants are able to regulate peripheral blood flow after changes of ambient humidity. With the method of laser Doppler flowmetry thermoregulatory responses in the microvascular bed can be measured in these infants.

  19. Biological risk versus socio-economic advantage: low birth-weight, multiple births and income variations among Irish infants born following fertility treatments.

    The Growing Up in Ireland Infant Cohort dataset (n = 11,134) includes information on fertility treatments for over 400 infants. IVF (28.1 %) and IVF-related treatments (17.8 %) were the most frequent, but there was also a high percentage following clomiphene citrate alone (31.5 %). Infants born following fertility treatment were much more likely to be in higher income families, and this relationship was not accounted for by older mothers in wealthier families. Analysis of fertility-treatment pregnancies among Irish infants, controlling for income and maternal age, shows a greater risk of multiple birth and low birth-weight, although the latter appears to be largely related to the former especially for IVF-type treatments.

  20. 'Resuscitation' of extremely preterm and/or low-birth-weight infants - time to 'call it'?

    Since ancient times, various methods have been used to revive apparently stillborn infants; many were of dubious efficacy and had the potential to cause harm. Based largely on studies of acutely asphyxiated term animal models, clinical assessment and positive pressure ventilation have become the cornerstones of neonatal resuscitation over the last 40 years. Over the last 25 years, care of extremely preterm infants in the delivery room has evolved from a policy of indifference to one of increasingly aggressive support. The survival of these infants has improved considerably in recent years; this has not, however, necessarily been due to more aggressive resuscitation. Urban myths have evolved that all extremely preterm infants died before they were intubated, and that all such infants need to immediately intubated or they will quickly die. This has never been true. Clinical assessment of infants at birth is subjective. Also, many techniques used to support preterm infants at birth have not been well studied and there is evidence that they may be harmful. It may thus be argued that many of our well-intentioned resuscitation interventions are of dubious efficacy and have the potential to cause harm. 'Resuscitation' is an emotive term which means 'restoration of life'. Death, thankfully, is a rare presentation in the delivery room. Therefore, concerning neonatal 'resuscitation', it is time to 'call it' something else. This will allow us to dispassionately distinguish preterm infants who are dead, or nearly dead, from those who are merely at high risk of parenchymal lung disease. We may then be able to refine our interventions and determine what methods of support benefit these infants most.

    Full Text Available Infant’s birth weight, especially low birth weight (LBW, areintergenerational issues that will affect the cycle of life.Vegetarian diets are at risk because limited food consumption could cause nutrient deficiencies. This retrospective studyaims to determine the relationship between maternal nutritional status (pre-pregnancy body mass index (BMI and weight gain during pregnancy and infant’s birth weight among vegetarians in Jakarta. The total sample of 85 children aged 1 month to 5 years was selected purposively. Results showed that the mean of pre-pregnancy BMI of vegetarian mothers is 20.2 kg/m2 (±2.2 kg/m2, pregnancy weight gain is 15.5 kg (±6.4 kg and infant’s birth weight is 3212 gs (±417.7 gs. Pre-pregnancy BMI and pregnancy weight gain were significantly associated with infant’s birth weight of vegetarians. There is no relationship between pre-pregnancy BMI and pregnancy weight gain. Multivariate analysis found that pre-pregnancy BMI, protein, vitamin B12, iron, and Zn intakes and sex has relationship with infant’s birthweight. It is recommended that vegetarian mothers should get information about the importance of pre-pregnancy nutrition, optimal pregnancy weight gain, and maintaining adequate intake of protein, vitamin B12, iron, and Zn during pregnancy

    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.

    Total body bone mineral density was measured by dual energy X-ray absorptiometry in 52 children who were very low birth weight (VLBW) infants without cerebral palsy and mental retardation (postconceptional age, from 10 mo to 6 y and 6 mo). VLBW infants in this study seemed to show compensatory acceleration of total body bone development, catching up with the control group during early childhood. However, in VLBW infants with at least one of the three factors such as total parenteral nutrition for 1 week or more, assisted ventilation for 1 week or more, or oxygen therapy for 28 d or more in their early stage after birth, adequate mineral supplementation might be especially important for long-term bone development.

    Full Text Available Background. Massage therapy (MT and kangaroo mother care (KMC are both effective in increasing the weight and reducing length of hospital stay in low birth weight preterm infants but they have not been compared. Aim. Comparison of effectiveness of MT and KMC on body weight and length of hospital stay in low birth weight preterm (LBWPT infants. Method. 30 LBWPT infants using convenience sampling from Neonatal Intensive Care Unit, V.S. hospital, were randomly divided into 2 equal groups. Group 1 received MT and Group 2 received KMC for 15 minutes, thrice daily for 5 days. Medically stable babies with gestational age < 37 weeks and birth weight < 2500 g were included. Those on ventilators and with congenital, orthopedic, or genetic abnormality were excluded. Outcome measures, body weight and length of hospital stay, were taken before intervention day 1 and after intervention day 5. Level of significance was 5%. Result. Data was analyzed using SPSS16. Both MT and KMC were found to be effective in improving body weight (P = 0.001, P = 0.001. Both were found to be equally effective for improving body weight (P = 0.328 and reducing length of hospital stay (P = 0.868. Conclusion. MT and KMC were found to be equally effective in improving body weight and reducing length of hospital stay. Limitation. Long term follow-up was not taken.

    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

    Full Text Available Abstract Background Genetic variation in the innate immune system of the host may play a role in determining the risk of developing infection, as well as outcome from infection. Methods Infectious complications were retrospectively determined in 293 (233 African-American (AA, 57 Caucasian and 3 Hispanic mechanically ventilated very low birth weight (VLBW infants ( Results The IL-6 -174C allele was associated with an increased incidence of late blood stream infection (BSI in AA but not Caucasian infants. In AA infants with the C allele the incidence of late BSI was 20/29 (69% compared to 94/204 (46% in homozygous GG infants (RR 2.6, 95% CI: 1.1–6.0, p = 0.021. The IL-10 -1082A allele was associated with an increased incidence of late BSI. One or more episodes of late BSI developed in 14 (35% of 40 infants with the GG genotype, 71 (49% of 145 infants with the GA genotype and 63 (58% of 108 infants with the AA genotype (p = 0.036. Infants with the A allele (AA or GA genotypes had an incidence of late BSI that was 134/253 (53% compared to 14/40 (35% in homozygous GG infants (RR 2.1, 95% CI: 1.04–4.19, p = 0.035. The CD14 -260 C/T SNP did not alter the overall risk for BSI in ventilated VLBW infants. Multiple BSI episodes were more common in the TT genotype group (CC: 17%, CT: 11%, TT: 30%, p = 0.022. This effect was due to the strong effect of the TT genotype on the incidence of multiple BSI in AA infants (CC: 15%, CT: 11%, TT: 39%, p = 0.003. Conclusion The IL-6 -174 G/C, IL-10 -1082 G/A and CD14 -260 C/T SNPs may alter risk for BSI in ventilated VLBW 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.

    Objective To analyze the clinical data of very low birth weight infants (VLBWIs) and extremely low birth weight infants (ELBWIs) (birth weight≤1 200 g) and to provide prewarning indicators for prognostic evaluation and clinical intervention. Methods A retrospective analysis was performed on the clinical data of 108 VLBWIs and ELBWIs to investigate the maternal history of diseases during pregnancy, neonatal birth status, the process of diagnosis and treatment, and prognosis. Unconditional logistic regression analysis was used to determine prognostic factors. Results Of the 108 preterm infants, 15 had a birth weight of<800 g, 29 had a birth weight of 800-999 g, and 64 had a birth weight of 1000-1200 g. The mortality was 33.3%(36/108). Placenta previa and Apgar score≤3 at 5 minutes were the main risk factors for death within 24 hours of birth;premature rupture of membrane, Apgar score≤3 at 5 minutes, and pulmonary hemorrhage were the main risk factors for death between 24 hours and 7 days after birth;late-onset sepsis caused by invasive fungal infection was an independent risk factor for death over 7 days after birth, while pregnancy-induced hypertension syndrome was a protective factor. Conclusions The mortality in VLBWIs and ELBWIs is relatively high, and the prognostic factors vary between preterm infants of different ages. Clinicians should discuss management options for the infants on the basis of these ifndings to increase the survival of preterm infants.%目的:分析极低及超低出生体重儿(出生体重≤1200 g)的临床资料,为其预后及临床干预提供预警指标。方法回顾性分析108例极低及超低出生体重儿的母孕期病史、新生儿出生时情况、诊治经过及预后,采用非条件logistic回归分析筛选预后的影响因素。结果108例极低及超低出生体重儿,出生体重范围在<800 g,800~999 g和1000~1200 g的早产儿分别为15例、29例和64例。存活72例,死亡36

    Full Text Available BACKGROUND: The current recommendation of giving the first dose of hepatitis B vaccine to very low birth weight (VLBW infants at 30 days of chronologic age usually is not practical, because most VLBW infants are not medically stable at that age. We use an alternative body-weight-based protocol, and evaluate its efficacy in an endemic area under a universal immunization program. METHODS: The immunogenicity of the current hepatitis B vaccination strategy in 155 VLBW preterm infants was evaluated at age 2 to 13 years, with parental consent. All of the infants were born between 1995 and 2006, and received their first dose of hepatitis B vaccine when they reached 2,000-2,200 g, irrespective of chronological age. Hepatitis B immunoglobulin (HBIG was given at birth to infants born to HBsAg(+/HBeAg(+ mothers. RESULTS: All 155 of the recruited children were HBsAg and anti-HBc negative. The anti-HBs seropositivity rate (geometric mean titer was 84.1% (146.5 mIU/mL for children under 3 years, 73.5% (68.8 mIU/mL for 4- to 7-year-olds, 27.7% (55.4 mIU/mL for 8- to 11-year-olds and 20% (6.0 mIU/mL for children ≥12 years of age. More than 90% of these children received the first vaccination after 30 days of age, half (51% at 60 to 90 days, and 29 children (18.6% after 90 days of age. Of the 26 infants born to HBsAg(+ mothers, 6/6 infants of HBeAg(+ mothers received HBIG at birth, and 12/20 infants of HBeAg(- mothers received HBIG. None of the 26 infants became infected. CONCLUSIONS: Delaying hepatitis B vaccinations in VLBW preterm infants until they reach a weight of 2,000 g, with the administration of HBIG at birth for infants of HBsAg(+ mothers provided adequate immunogenicity and protection in a highly endemic area. Weight-based policy of hepatitis B vaccination is an effective and practical alternative strategy for VLBW infants.

    This study aimed to investigate current therapeutic strategies for patent ductus arteriosus (PDA) in very-low-birth-weight (VLBW) infants in Korea. A total of 2,254 VLBW infants among 2,386 from Korean Neonatal Network cohort born from January 2013 to June 2014 were included. No PDA was seen for 1,206 infants (53.5%) and the infants diagnosed or treated for PDA were 1,048 infants (46.5%). The proportion of infants with PDA was decreased according to the increase in gestational age (GA) and birthweight. Infants with PDA were divided into groups according to the therapeutic strategies of PDA: prophylactic treatment (PT, n = 69, 3.1%), pre-symptomatic treatment (PST, n = 212, 9.4%), symptomatic treatment (ST, n = 596, 26.4%), and conservative treatment (CT, n = 171, 7.6%). ST was the most preferred treatment modality for preterm PDA and the proportion of the patients was decreased in the order of PST, CT, and PT. Although ST was still the most favored treatment in GA < 24 weeks group, CT was more preferred than PST or ST when compared with GA ≥ 32 weeks group [CT vs. PST, OR 5.3, 95% CI 1.56-18.18; CT vs. ST, OR 2.9, 95% CI 1.03-8.13]. A total of 877 infants (38.9%) received pharmacological or surgical treatment about PDA, and 35.5% (801 infants) received pharmacological treatment, mostly with ibuprofen. Seventy-six infants (3.4%) received primary ligation and 8.9% (201 infants) received secondary ligation. Diverse treatment strategies are currently used for preterm PDA in Korea. Further analyses of neonatal outcomes according to the treatment strategies are necessary to obtain a standardized treatment guideline for preterm PDA.

    Full Text Available OBJECTIVE: to evaluate neonatal sepsis as a risk factor for abnormal neuromotor and cognitive development in very low birth weight preterm infants at 12 months of corrected age. METHODS: this was a prospective cohort study that followed the neuromotor and cognitive development of 194 very low birth weight preterm infants discharged from a public neonatal intensive care unit. The Bayley Scale of Infant Development (second edition at 12 months of corrected age was used. The outcomes were the results of the clinical/neurological evaluation and the scores of the psychomotor development index (PDI and mental development index (MDI of the Bayley Scale of Infant Development II. The association between neonatal sepsis and neuromotor development and between neonatal sepsis and cognitive development was verified by logistic regression analysis. RESULTS: mean birth weight was 1,119 g (SD: 247 and mean gestational age was 29 weeks and 6 days (SD: 2. Approximately 44.3%(n = 86 of the infants had neonatal sepsis and 40.7% (n = 79 had abnormal neuromotor development and/or abnormal psychomotor development index (PDI < 85 at 12 months of corrected age. On the mental scale, 76 (39.1% children presented abnormal cognitive development (MDI < 85. Children with neonatal sepsis were 2.5 times more likely to develop changes in neuromotor development (OR: 2.50; CI: 1.23-5.10. There was no association between neonatal sepsis and cognitive development impairment. CONCLUSION: neonatal sepsis was an independent risk factor for neuromotor development impairment at 12 months of corrected age, but not for mental development impairment.

    Background: With the progress of perinatal medicine and neonatal technology, more and more extremely low birth weight (ELBW) survived all over the world. This study was designed to investigate the short-term outcomes of ELBW infants during their Neonatal Intensive Care Unit (NICU) stay in the mainland of China. Methods: All infants admitted to 26 NICUs with a birth weight (BW) < l000 g were included between January l, 2011 and December 31, 2011. All the data were collected retrospectively from clinical records by a prospectively designed questionnaire. The data collected from each NICU transmitted to the main institution where the results were aggregated and analyzed. Categorical variables were performed with Pearson Chi-square test. Binary Logistic regression analysis was used to detect risk factors. Results: A total of 258 ELBW infants were admitted to 26 NICUs, of whom the mean gestational age (GA) was 28.1 ± 2.2 weeks, and the mean BW was 868 ± 97 g. The overall survival rate at discharge was 50.0%. Despite aggressive treatment 60 infants (23.3%) died and another 69 infants (26.7%) died after medical care withdrawal. Furthermore, the survival rate was significantly higher in coastal areas than inland areas (53.6% vs. 35.3%, P = 0.019). BW < 750 g and GA < 28 weeks were the largest risk factors, and being small for gestational age was a protective factor related to mortality. Respiratory distress syndrome was the most common complication. The incidence of patent ductus arteriosus, intraventricular hemorrhage, periventricular leukomalacia, bronchopulmonary dysplasia, retinopathy of prematurity was 26.2%, 33.7%, 6.7%, 48.1%, and 41.4%, respectively. Ventilator associated pneumonia was the most common hospital acquired infection during hospitalization. Conclusions: Our study was the first survey that revealed the present status of ELBW infants in the mainland of China. The mortality and morbidity of ELBW infants remained high as compared to other developed

    BACKGROUND: Human milk banking has been available in many countries for the last three decades. The milk provided from milk banking is predominantly term breast milk, but some milk banks provide preterm breast milk. There are a number of differences between donor term and donor preterm human milk. OBJECTIVES: To determine the effect of banked preterm milk compared with banked term milk regarding growth and developmental outcome in very low birth weight infants (infants weighing less than 1500 g). SEARCH STRATEGY: We used the standard methods of the Cochrane Neonatal Review Group, including a search of the Cochrane Neonatal Group specialized register and the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, January 2010). We searched the computerised bibliographic databases MEDLINE (1966 to February 2010), EMBASE (1988 to February 2010) and Web of Science (1975 to February 2010). We searched reference lists of all selected articles, review articles and the Oxford Database of Perinatal Trials. We also searched abstracts from neonatal and pediatric meetings (PAS electronic version from 2000 to 2009, ESPR hand search from 2000 to 2009). We applied no language restrictions. SELECTION CRITERIA: Randomised and quasi-randomised trials comparing banked donor preterm milk with banked donor term milk regarding growth and developmental outcomes in very low birth weight infants DATA COLLECTION AND ANALYSIS: We planned to perform assessment of methodology regarding blinding of randomisation, intervention and outcome measurements as well as completeness of follow-up. We planned to evaluate treatment effect using a fixed-effect model using relative risk (RR), relative risk reduction, risk difference (RD) and number needed to treat (NNT) for categorical data and using mean, standard deviation and weighted mean difference (WMD) for continuous data. We planned an evaluation of heterogeneity. MAIN RESULTS: No studies met the inclusion criteria. AUTHORS

    Janet M Wojcicki

    Full Text Available BACKGROUND: Latino children are at increased risk for mirconutrient deficiencies and problems of overweight and obesity. Exposures in pregnancy and early postpartum may impact future growth trajectories. OBJECTIVES: To evaluate the relationship between prenatal and postnatal maternal depressive symptoms experienced in pregnancy and infant growth from birth to 2 years of age in a cohort of Latino infants. METHODS: We recruited pregnant Latina mothers at two San Francisco hospitals and followed their healthy infants to 24 months of age. At 6, 12 and 24 months of age, infants were weighed and measured. Maternal depressive symptoms were assessed prenatally and at 4-6 weeks postpartum. Women who had high depressive symptoms at both time periods were defined as having chronic depression. Logistic mixed models were applied to compare growth curves and risk for overweight and underweight based on exposure to maternal depression. RESULTS: We followed 181 infants to 24 months. At 12 and 24 months, respectively, 27.4% and 40.5% were overweight, and 5.6% and 2.2% were underweight. Exposure to chronic maternal depression was associated with underweight (OR = 12.12, 95%CI 1.86-78.78 and with reduced weight gain in the first 2 years of life (Coef = -0.48, 95% CI -0.94-0.01 compared with unexposed infants or infants exposed to episodic depression (depression at one time point. Exposure to chronic depression was also associated with reduced risk for overweight in the first 2 years of life (OR 0.28, 95%CI 0.03-0.92. CONCLUSIONS: Exposure to chronic maternal depression in the pre- and postnatal period was associated with reduced weight gain in the first two years of life and greater risk for failure to thrive, in comparison with unexposed infants or those exposed episodically. The infants of mothers with chronic depression may need additional nutritional monitoring and intervention.

    We analyzed the characteristics associated with the growth in weight of Japanese triplets from birth to 12 years of age. The study included 376 mothers and their 1,128 triplet children, who were born between 1978 and 2006. Data were collected through a mailed questionnaire sent to the mothers asking for information recorded in medical records. For these births, data on triplets' weight growth, gestational age, sex, parity, maternal age at delivery, maternal height, and maternal body mass index were obtained from records in the Maternal and Child Health Handbooks and records in the school where children receive health check-ups. The weight deficit of the triplets compared to the general population of Japan remained between 10% and 17% until 12 years of age. Moreover, at 12 years of age, the differences of weight between the general population and triplets were approximately -4.75 kg for boys and -6.00 kg for girls. Very low birth weight had the strongest contribution to body weight until 8 years of age. After 8 years of age, maternal body mass index was a significant factor affecting the weight of triplets until 12 years of age.

    Full Text Available It was the aim of our study to evaluate the independent effect of preterm prelabor rupture of membranes (PPROM as a cause of preterm delivery on mortality during primary hospital stay and significant morbidities in very-low-birth-weight (VLBW infants < 32 weeks of gestation.Observational, epidemiological study design.Population-based cohort, German Neonatal Network (GNN.6102 VLBW infants were enrolled in GNN from 2009-2012, n=4120 fulfilled criteria for primary analysis (< 32 gestational weeks, no pre-eclampsia, HELLP (highly elevated liver enzymes and low platelets syndrome or placental abruption as cause of preterm birth.Multivariable logistic regression analyses included PPROM as potential risk factors for adverse outcomes and well established items such as gestational age in weeks, birth weight, antenatal steroids, center, inborn delivery, multiple birth, gender and being small-for-gestational-age.PPROM as cause of preterm delivery had no independent effect on the risk of early-onset sepsis, clinical sepsis and blood-culture proven sepsis, while gestational age proved to be the most important contributor to sepsis risk. The diagnosis of PPROM was associated with an increased risk for bronchopulmonary dysplasia (BPD; OR: 1.25, 95% CI: 1.02-1.55, p=0.03 but not with other major outcomes.The diagnosis of PPROM per se is not associated with adverse outcome in VLBW infants < 32 weeks apart from a moderately increased risk for BPD. Randomized controlled trials with primary neonatal outcomes are needed to determine which subgroup of VLBW infants benefit from expectant or intentional management of PPROM.

    Full Text Available OBJECTIVES: To compare mortality and morbidity in very low birth weight infants (VLBWI born to women with and without diabetes mellitus (DM. METHODS: This was a cohort study with retrospective data collection (2001-2010, n = 11.991 from the NEOCOSUR network. Adjusted odds ratios and 95% confidence intervals were calculated for the outcome of neonatal mortality and morbidity as a function of maternal DM. Women with no DM served as the reference group. RESULTS: The rate of maternal DM was 2.8% (95% CI: 2.5-3.1, but a significant (p = 0.019 increase was observed between 2001-2005 (2.4%, 2.1-2.8 and 2006-2010 (3.2%, 2.8-3.6. Mothers with DM were more likely to have received a complete course of prenatal steroids than those without DM. Infants of diabetic mothers had a slightly higher gestational age and birth weight than infants of born to non-DM mothers. Distribution of mean birth weight Z-scores, small for gestational age status, and Apgar scores were similar. There were no significant differences between the two groups regarding respiratory distress syndrome, bronchopulmonary dysplasia, intraventricular hemorrhage, periventricular leukomalacia, and patent ductus arteriosus. Delivery room mortality, total mortality, need for mechanical ventilation, and early-onset sepsis rates were significantly lower in the diabetic group, whereas necrotizing enterocolitis (NEC was significantly higher in infants born to DM mothers. In the logistic regression analysis, NEC grades 2-3 was the only condition independently associated with DM (adjusted OR: 1.65 [95% CI: 1.2 -2.27]. CONCLUSIONS: VLBWI born to DM mothers do not appear to be at an excess risk of mortality or early morbidity, except for NEC.

    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 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.

    Full Text Available Abstract Objective To determine the effects of high dietary protein and energy intake on the growth and body composition of very low birth weight (VLBW infants. Study design Thirty-eight VLBW infants whose weights were appropriate for their gestational ages were assessed for when they could tolerate oral intake for all their nutritional needs. Thirty-two infants were included in a longitudinal, randomized clinical trial over an approximate 28-day period. One control diet (standard preterm formula, group A, n = 8, 3.7 g/kg/d of protein and 129 kcal/kg/d and two high-energy and high-protein diets (group B, n = 12, 4.2 g/kg/d and 150 kcal/kg/d; group C, n = 12, 4.7 g/kg/d and 150 kcal/kg/d were compared. Differences among groups in anthropometry and body composition (measured with bioelectrical impedance analysis were determined. An enriched breast milk group (n = 6 served as a descriptive reference group. Results Groups B and C displayed greater weight gains and higher increases in fat-free mass than group A. Conclusion An intake of 150 kcal/kg/d of energy and 4.2 g/kg/d of protein increases fat-free mass accretion in VLBW 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.

    Objective:To analyze the clinical effects of glutamine assisted enteral nutrition and parenteral nutrition on improving the feeding intolerance of low birth weight infants.Methods: A total of 40 cases of low birth weight infants (LBW) in our hospital from May 2013 to June 2015 were selected, which were divided equally into the observation group and the control group according to the different nutritional intervention methods. Patients in the control group received routine enteral nutrition and parenteral nutrition while children of observed group received glutamine assisted enteral and parenteral nutrition. Differences of children’s growth and development indicators, nutritional status and levels of calcium and phosphorus, gastrin and motilin levels, mucosal barrier and immune function were compared between two groups. Results:After receiving nutritional intervention, children in the observation group had higher levels of serum leptin, GH, IGF-I and adiponectin than the control group patients, while Cor values were lower. The observation group patients who received nutritional intervention had higher TSF, AMC, TP, ALB, calcium and phosphorus levels than the control group, while the ALP values were lower; children of observation group who received nutrition intervention had higher GAS and MOT levels than the control group; children of observation group after intervention had higher peripheral blood CD3+T, CD4+T and CD4+/CD8+ levels than the control group children, while D-lactic acid and blood ammonia levels were lower.Conclusion:Glutamine assisted enteral nutrition and parenteral nutrition could improve the feeding intolerance of low birth weight infants, and it improved the nutritional status as well as growth and development of children as a whole, and thus had positive clinical significance.

    OBJECTIVE: Recent evidence suggests that high cortisol concentrations are associated with increased morbidity and mortality in very low birth weight (VLBW) infants. Neonatal illness severity and mortality risk scores are reliable in predicting morbidity and mortality. The objectives were (i) to assess the correlation between serum cortisol levels and clinical assessment of multi-organ dysfunction\\/illness severity scores (CRIB II, SNAPPE-II and neonatal multiple organ dysfunction score (NEOMOD)) in first 24 h in VLBW infants and (ii) to assess the relationship between surrogates of end organ blood flow and serum cortisol levels. STUDY DESIGN: A prospective observational cohort study. Neonates with birth weight <1500 g were eligible for enrollment. Echocardiography evaluation of superior vena cava (SVC) flow was carried out in the first 24 h life. Cortisol levels were measured simultaneously and appropriate clinical scores were calculated. RESULT: A total of 54 VLBW neonates were enrolled following parental consent. Two patients were excluded because of congenital malformations. In 14 babies the cortisol value was not simultaneously obtained. The mean birth weight was 1.08 kg, mean gestational age was 27.8 weeks. There was a significant correlation between cortisol and NEOMOD score (P=0.006). There was no correlation between cortisol and CRIB II score (P=0.34), SVC flow (P=0.49) and mean arterial blood pressure respectively (P=0.35). CONCLUSION: There was no correlation between SVC flow and cortisol values or between cortisol and mean blood pressure values. There was a significant correlation between cortisol levels and neonatal organ dysfunction score evaluated suggesting that stressed VLBW infants do mount a cortisol response.

    Full Text Available INTRODUCTION: The purpose of this study was to establish the late onset sepsis (LOS rate of our service, characterize the intestinal microbiota and evaluate a possible association between gut flora and sepsis in surgical infants who were receiving parenteral nutrition (PN. METHODS: Surveillance cultures of the gut were taken at the start of PN and thereafter once a week. Specimens for blood culture were collected based on clinical criteria established by the medical staff. The central venous catheter (CVC tip was removed under aseptic conditions. Standard laboratory methods were used to identify the microorganisms that grew on cultures of gut, blood and CVC tip. RESULTS: 74 very low birth weight infants were analyzed. All the infants were receiving PN and antibiotics when the gut culture was started. In total, 21 (28.4% infants experienced 28 episodes of LOS with no identified source. Coagulase negative staphylococci were the most common bacteria identified, both in the intestine (74.2% and blood (67.8%. All infections occurred in patients who received PN through a central venous catheter. Six infants experienced episodes of microbial translocation. CONCLUSIONS: In this study, LOS was the most frequent episode in neonates receiving parenteral nutrition who had been submitted to surgery; 28.6% of this infection was probably a gut-derived phenomenon and requires novel strategies for prevention.

    Moran, M

    2012-02-01

    BACKGROUND: Superior vena cava (SVC) flow assesses blood flow from the upper body, including the brain. Near infrared spectroscopy (NIRS) provides information on brain perfusion and oxygenation. AIM: To assess the relationship between cerebral tissue oxygenation index (cTOI) and cardiac output measures in the very low birth weight (VLBW) infant in the first day of life. METHODS: A prospective observational cohort study. Neonates with birth weight less than 1500 g (VLBW) were eligible for enrollment. Newborns with congenital heart disease, major congenital malformations and greater than Papile grade1 Intraventricular Haemorrhage on day 1 of life were excluded. Echocardiographic evaluation of SVC flow was performed in the first 24 h of life. Low SVC flow states were defined as a flow less than 40 mL\\/kg\\/min. cTOI was measured using NIRO 200 Hamamatsu. RESULTS: Twenty-seven VLBW neonates had both echocardiography and NIRS performed. The median (range) gestation was 29\\/40 (25 + 3 to 31 + 5 weeks) and median birth weight was 1.2 kg (0.57-1.48 kg). The mean (SD) TOI was 68.1 (7.9)%. The mean (SD) SVC flow was 70.36(39.5) mLs\\/kg\\/min. The correlation coefficient of cerebral tissue oxygenation and SVC flow was r = 0.53, p-value 0.005. There was a poor correlation between right and left ventricular output and cTOI which is not surprising considering the influence of intra- and extracardiac shunts. CONCLUSION: There is a positive relationship between cerebral TOI values and SVC flow in the very low birth infant on day one of life.

    Necrotizing enterocolitis (NEC) is a critical intestinal emergency condition, which mainly occurs in preterm very low birth weight (PVLBW) infants. Despite remarkable advances in the care of PVLBW infants, with considerable improvement of the survival rate in recent decades, the incidence of NEC...... and NEC-related mortality have not declined accordingly. The fast progression from nonspecific signs to extensive necrosis also makes primary prevention the first priority. Recently, increasing evidence has indicated the important role of several nutrients in primary prevention of NEC. Therefore, the aim...... of this review is to summarize some potential immunomodulatory nutrients in the prevention of NEC, including bovine colostrum, probiotics, prebiotics (e.g., human milk oligosaccharides), long chain polyunsaturated fatty acids, and amino acids (glutamine, cysteine and N-acetylcysteine, l-arginine and l...

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

    Full Text Available Background: With the progress of perinatal medicine and neonatal technology, more and more extremely low birth weight (ELBW survived all over the world. This study was designed to investigate the short-term outcomes of ELBW infants during their Neonatal Intensive Care Unit (NICU stay in the mainland of China. Methods: All infants admitted to 26 NICUs with a birth weight (BW < l000 g were included between January l, 2011 and December 31, 2011. All the data were collected retrospectively from clinical records by a prospectively designed questionnaire. The data collected from each NICU transmitted to the main institution where the results were aggregated and analyzed. Categorical variables were performed with Pearson Chi-square test. Binary Logistic regression analysis was used to detect risk factors. Results: A total of 258 ELBW infants were admitted to 26 NICUs, of whom the mean gestational age (GA was 28.1 ± 2.2 weeks, and the mean BW was 868 ± 97 g. The overall survival rate at discharge was 50.0%. Despite aggressive treatment 60 infants (23.3% died and another 69 infants (26.7% died after medical care withdrawal. Furthermore, the survival rate was significantly higher in coastal areas than inland areas (53.6% vs. 35.3%, P = 0.019. BW < 750 g and GA < 28 weeks were the largest risk factors, and being small for gestational age was a protective factor related to mortality. Respiratory distress syndrome was the most common complication. The incidence of patent ductus arteriosus, intraventricular hemorrhage, periventricular leukomalacia, bronchopulmonary dysplasia, retinopathy of prematurity was 26.2%, 33.7%, 6.7%, 48.1%, and 41.4%, respectively. Ventilator associated pneumonia was the most common hospital acquired infection during hospitalization. Conclusions: Our study was the first survey that revealed the present status of ELBW infants in the mainland of China. The mortality and morbidity of ELBW infants remained high as compared to other

    We sought to determine the association between small for gestational age (SGA), birth weight, and childhood obesity within preterm polysubstance exposed children. We sampled 312 preterm children with 11-year body mass index (BMI; age- and sex-specific) data from the Maternal Lifestyle Study (51% girls, 21.5% SGA, 46% prenatal cocaine, and 55% tobacco exposed). Multinomial regression analyzed the association between 11-year obesity (OBE) and overweight (OW) and SGA, birth weight, first-year growth velocity, diet, and physical activity variables. Overall, 24% were OBE (BMI for age ≥95th percentile) and 16.7% were OW (BMI ≥85th and <95th percentiles). In adjusted analyses, SGA was associated with OW (odds ratio [OR]=3.4, confidence interval [CI] 1.5 to 7.5). Higher birth weight was associated with OBE (OR = 1.8, CI 1.3 to 2.4) and OW (OR=1.4, CI 1.1 to 2.0). Growth velocity was associated with OBE (OR=2.7, CI 1.8 to 4.0) and OW (OR=1.6, CI 1.1 to 2.4). Low exercise was associated with OBE (OR=2.1, CI 1.0 to 4.4) and OW (OR=2.1, CI 1.0 to 4.5). There was no effect of substance exposure on obesity outcomes. Many (41%) of these high-risk preterm 11-year-olds were obese/overweight. Multiple growth-related processes may be involved in obesity risk for preterm children, including fetal programming as indicated by the SGA effect. PMID:20408111

    Full Text Available This study investigated possible prenatal and neonatal variables that may influence the prevalence of tooth enamel hypoplasia in preterm and low birth weight children (LBW and a matched control group of term children with normal birth weight (NBW. The study sample consisted of 61 children born preterm and with LBW examined at 18-34 months of age. The control group was formed by 61 infants born full term and with NBW examined at 31-35 months of age. All children were born at the Center of Integrated Attention of Women's Health (CAISM-UNICAMP. FDI criteria were followed for dental examination. Medical data was collected retrospectively from hospital records. Among preterms, 57.4% had some type of developmental defects of enamel (DDE, 52.5 % had opacities and 21.3 % presented hypoplasia. Among full-term children, 24.6% presented DDE, 24.6% had opacities and 3.3% had hypoplasia. LBW preterm infants presented a higher prevalence of hypoplasia than NBW controls. The deciduous teeth most affected by hypoplasia were maxillary incisors. There was no significant association with prenatal variables; among neonatal variables there was a significant association with respiratory distress syndrome and neurological examination at discharge with an altered result.

    Objective To estimate associations of exclusive human milk (EHM) feedings with growth and neurodevelopment through 18 months corrected age (CA) in extremely low birth weight (ELBW) infants. Study Design ELBW infants admitted from July 2011 to June 2013 who survived were reviewed. Infants managed from July 2011 to June 2012 were fed with bovine milk-based fortifiers and formula (BOV). Beginning in July 2012, initial feedings used a human milk-based fortifier to provide EHM feedings. Infants were grouped on the basis of feeding regimen. Primary outcomes were the Bayley-III cognitive scores at 6, 12, and 18 months and growth. Results Infants (n = 85; 46% received EHM) were born at 26 ± 1.9 weeks (p = 0.92 between groups) weighing 776 ± 139 g (p = 0.67 between groups). Cognitive domain scores were similar at 6 months (BOV: 96 ± 7; EHM: 95 ± 14; p = 0.70), 12 months (BOV: 97 ± 10; EHM: 98 ± 9; p = 0.86), and 18 months (BOV: 97 ± 16; EHM: 98 ± 14; p = 0.71) CA. Growth velocity prior to discharge (BOV: 12.1 ± 5.2 g/kg/day; EHM: 13.1 ± 4.0 g/kg/day; p = 0.33) and subsequent growth was similar between groups. Conclusion EHM feedings appear to support similar growth and neurodevelopment in ELBW infants as compared with feedings containing primarily bovine milk-based products.

    Full Text Available Abstract Background Very low birth weight (VLBW infants ( Methods Comprehensive lung function assessment was performed at about 50, 70, and 100 weeks of postmenstrual age in 55 sedated VLBW infants (29 with former BPD [O2 supplementation was given at 36 weeks of gestational age] and 26 VLBW infants without BPD [controls]. Mean gestational age (26 vs. 29 weeks, birth weight (815 g vs. 1,125 g, and the proportion of infants requiring mechanical ventilation for ≥7 d (55% vs. 8%, differed significantly between BPD infants and controls. Results Both body weight and length, determined over time, were persistently lower in former BPD infants compared to controls, but no significant between-group differences were noted in respiratory rate, respiratory or airway resistance, functional residual capacity as determined by body plethysmography (FRCpleth, maximal expiratory flow at the FRC (V'max FRC, or blood gas (pO2, pCO2 levels. Tidal volume, minute ventilation, respiratory compliance, and FRC determined by SF6 multiple breath washout (representing the lung volume in actual communication with the airways were significantly lower in former BPD infants compared to controls. However, these differences became non-significant after normalization to body weight. Conclusions Although somatic growth and the development of some lung functional parameters lag in former BPD infants, the lung function of such infants appears to develop in line with that of non-BPD infants when a body weight correction is applied. Longitudinal lung function testing of preterm infants after discharge from hospital may help to identify former BPD infants at risk of incomplete recovery of respiratory function; such infants are at risk of later respiratory problems.

    Full Text Available The ability to regulate emotion is a crucial process that humans utilize in order to adapt to the demands of environmental constraints. Individuals exposed to early adverse life events such as being born at an extremely low birth weight (ELBW, 501–1000 g are known to have problems regulating emotion which have been linked to the development of psychopathology in this population. Recent studies have used psychophysiological measures, such as electroencephalogram (EEG and cardiac vagal tone, to index emotion regulatory processes. The purpose of this paper was three-fold: (1 to investigate the relation between ELBW and emotion regulation issues (pathway 1, (2 to review studies investigating the relation between early emotion regulation and later internalizing problems (pathway 2; and (3 to provide a model in which two psychophysiological measures (i.e., frontal EEG asymmetry and cardiac vagal tone are suggested to understand the proposed conceptual pathways in the relation between ELBW and psychopathology.

    Full Text Available Background: Establishment and maintenance of breastfeeding in preterm low birth weight (PT LBW neonates after discharge from hospital is challenging and may be affected by multiple factors. We designed this study to find out the association of these factors with breastfeeding in our population. Objectives: To observe the rate of exclusive breasrfeeding (EBF among the PT LBW neonates at one month follow up and to identify the factors that are related with the maintenance of EBF. Materials and Methods: This observational study was conducted during the period from July 2009 to October 2011 in Enam Medical College Hospital (EMCH. Preterm infants ≤ 34 wks gestation, stayed in the NICU for >3 days and discharged home were eligible. Mothers were interviewed at one month follow-up after discharge. Infants who were given only breast milk up to 4 weeks were termed as “Exclusively breastfed (EBF” and who were given formula milk in addition were labeled as “Nonexclusively breastfed (NEBF”. Baseline information regarding maternal demography, delivery of the baby, feeding during discharge was taken from database of neonatal ward. Results: Among 89 infants, 37 (42% were female and 52 (58% were male, including 5 twins. Gestational age ranged from 29 to 34 weeks (mean 32±2, and birth weight ranged from 1100 to 2200 grams (mean 1763±20 g. At one month follow up visit 19% (17/89 were found to be NEBF and 81% were EBF. Factors significantly associated with EBF were shorter duration of hospital stay (p=0.001, method of feeding at discharge (p=0.001, mode of delivery (p=0.004, below average socio-economic status (p=0.03, maternal education (p=0.02, number of antenatal visits (p=0.02 and larger birth weight (p=0.038. Conclusion: A variety of factors may affect EBF in PT LBW babies. Extensive counseling of the mothers during antenatal visits, counseling of the family members regarding the advantages of exclusive breastfeeding is necessary. Support should be

    Full Text Available Our purpose was to determine mortality and morbidity rates and selected outcome variables for infants weighing less than 1500 g, who were admitted to the neonatal care unit of our hospital from April 2005 to February 2006.The number of VLBW admissions to the our neonatal care unit was 91, fourty one percent female and %49 were male. The mean birth weight was 1191±261 g and gestational age was 29±2.4 weeks. The mortality rate was 37.3 %. Antenatal steroids had been given to only 8% of mothers. The most important maternal risk factors were preeclampsia/eclampsia 30%, premature rupture of membranes 13%, hemorhage 8%. Respiratory distress syndrome was diagnosed 47%, surfactant was given to 40% of these infants. The major causes of death were sepsis, respiratuar distres syndrome, and extreme prematurity.Compared with reports from other developed NICU, VLBW infants at our center had higher mortality rates. We conclude that, the major cause of high mortality rate depends on low-social –cultural –education conditions associated with insufficient prenatal care, neonatal care and inaccurate neonatal transport in our region.

    Psychological stress responses may have both emotional and cortisol reactivity correlates, but there are limited data addressing the association between generalized negative and positive emotional states and cortisol reactivity to a psychological stressor among infants born very low birth weight (VLBW; cortisol) responses may provide insight into the nature of regulation difficulties identified in infants born VLBW. The purpose of this study was to assess the association between infant affective and cortisol responses to the Still Face paradigm (SF) in a cohort of six- to eight-month old infants born VLBW compared with infants born full-term (N=53 total; N=29 and N=24, respectively). Infant affect was coded in 1-s intervals while mother-infant dyads participated in the SF paradigm, and percent positive affect and percent negative affect were calculated separately for each SF episode. We had hypothesized that because infants born VLBW are at increased risk for dysregulation, they would show, compared to full-term controls, greater dysregulation in the form of less synchrony (i.e., less correlated affective and cortisol responses) across the two SF stressors (episodes 2 and 4). This hypothesis was largely supported: the associations between affective and cortisol responses were different for the two groups across the two stressors for percent positive affect (both stressor episodes 2 and 4) and percent negative affect (episode 4 only). For the full-term group, follow up correlations revealed significant negative associations between percent positive affective and cortisol responses for both stressors. Mothers' responsiveness did not explain the term group association differences between infant affective and cortisol responses across stressors. The (lack of) association of stress reactivity systems may index dysregulation or dysregulation correlates in preterm children. Understanding how this lack of coordination among stress systems relates to greater dysregulation

    Parenterally fed preterm neonates are known to be at risk for carnitine deficiency. We studied substrate utilization in low-birth-weight infants receiving total parenteral nutrition (TPN) with (A) and without (B) supplementation of 48 mg carnitine.kg-1.d-1 on days 4-7 (birth weights 1334 +/- 282 vs 1318 +/- 248 g, gestational age 32 +/- 2 vs 32 +/- 2 wk, A vs B, respectively). TPN consisted of 11 g glucose.kg-1.d-1 and 2.4 g.kg-1.d-1 of both protein and fat. Plasma carnitine concentrations at day 7 were for free carnitine 11.8 +/- 5.0 vs 164 +/- 56 mumol/L and for acyl carnitine 3.8 +/- 2.0 vs 33.9 +/- 15.4 mumol/L, respectively. Indirect calorimetry at day 7 showed a higher fat oxidation (0.21, -0.31 to +0.60 vs 1.18, 0.70 to 1.95 g. kg-1.d-1, respectively, P less than 0.02, median and interquartile range) in group B and a higher protein oxidation (0.37, 0.30-0.43 vs 0.63, 0.53-0.88 g.kg-1.d-1, P less than 0.001). The time to regain birth weight was also higher in group B (7, 5.5-9 vs 9, 7-14 d, P less than 0.05). Carnitine supplementation and calorie intake were the best explanatory variables for metabolic rate (R2 = 0.45, P less than 0.002). We conclude that carnitine supplementation of TPN in this dosage does not seem advisable.

  10. Is there any role for terlipressin in the extremely low birth weight infant with refractory septic shock?

    Full Text Available Terlipressin, a synthetic long-acting analogue of vasopressin, has been investigated as a second line vasopressor in adults and children with refractory septic shock, i.e. not responding to fluid resuscitation and high-dose catecholamine administration. Little experience is available about the safety and efficacy of terlipressin in term and preterm newborns. We report the case of an extremely low birth weight infant with severe septic shock, unresponsive to fluids, noradrenalin and hydrocortisone, in whom terlipressin was attempted as a rescue drug. Despite three doses of terlipressin, administered 6-hourly, the patient remained profoundly hypotensive and eventually died. Further studies are required before any recommendation on the use of terlipressin in term or preterm newborns with septic shock can be made.

    The use of caffeine citrate for treatment of apnea in very low birth weight infants showed short-term and long-term benefits. A systematic review and meta-analysis of the literature was undertaken to document the effect providing caffeine early (0-2 days of life) compared to providing caffeine late (≥3 days of life) in very low birth weight infants on several neonatal outcomes, including bronchopulmonary dysplasia (BPD). We searched MEDLINE, the EMBASE database, the Cochrane Library, and KoreaMed for this meta-analysis. The quality of the included studies was assessed using the Newcastle-Ottawa Scale and Jadad's scale. Studies were included if they examined the effect of the early use of caffeine compared with the late use of caffeine. Two reviewers screened the candidate articles and extracted the data from the full-text of all of the included studies. We included a total of 59,136 participants (range 58,997-59,136; variable in one study) from a total of 5 studies. The risk of death (odds ratio [OR], 0.902; 95% confidence interval [CI], 0.828 to 0.983; P=0.019), bronchopulmonary dysplasia (BPD) (OR, 0.507; 95% CI, 0.396 to 0.648; Pcaffeine group. Early caffeine use was not associated with a risk of necrotizing enterocolitis (NEC) and NEC requiring surgery. This meta-analysis suggests that early caffeine use has beneficial effects on neonatal outcomes, including mortality and BPD, without increasing the risk of NEC.

    We investigated the effects of a year-long home intervention with a sample of preterm infants randomly assigned to 1 of 3 groups: a developmental intervention, a parent-infant intervention, and a no-treatment control group. A full-term no-treatment control was also used. Both intervention approaches focused on the parent-child unit, providing training for parents to improve observational skills, emotional support, and information about community resources. However, whereas specific tasks to facilitate the child's development were provided in the developmental intervention group, the quality of the parent-infant interaction was the target for treatment in the other group. All infants were assessed at 4, 8, 12, and 16 months of age corrected for prematurity. The results suggest that although both intervention approaches were effective in modifying some aspects of the home environment and, to a lesser degree, in improving infants' cognitive development, the parent-infant interaction approach seemed to have the greater impact. These findings confirm previous observations regarding the cognitive development of preterm and full-term infants during the first 18 months of life and demonstrate changes in behavior and behavior styles in both pre- and full-term infants as they become older.

    2015-08-01

    Full Text Available Necrotizing enterocolitis (NEC is a critical intestinal emergency condition, which mainly occurs in preterm very low birth weight (PVLBW infants. Despite remarkable advances in the care of PVLBW infants, with considerable improvement of the survival rate in recent decades, the incidence of NEC and NEC-related mortality have not declined accordingly. The fast progression from nonspecific signs to extensive necrosis also makes primary prevention the first priority. Recently, increasing evidence has indicated the important role of several nutrients in primary prevention of NEC. Therefore, the aim of this review is to summarize some potential immunomodulatory nutrients in the prevention of NEC, including bovine colostrum, probiotics, prebiotics (e.g., human milk oligosaccharides, long chain polyunsaturated fatty acids, and amino acids (glutamine, cysteine and N-acetylcysteine, l-arginine and l-citrulline. Based on current research evidence, probiotics are the most documented effective method to prevent NEC, while others still require further investigation in animal studies and clinical randomized controlled trials.

    This 1998 study investigated the association between intake of fish and fish oil during pregnancy and full-term infants' size at birth in an Icelandic fishing community. Healthy women aged 20-40 years of normal weight before pregnancy (body mass index: 19.5-25.5 kg/m(2)) and at 38-43 weeks of gestation were selected randomly. Information on infant size at birth was collected from maternity records. Intake of fish and fish oil in pregnancy was ascertained (n = 491, 80.1%) by using a validated, focused, food frequency questionnaire. Infants of women in the lowest quartile of fish consumption weighed less (p = 0.036), were shorter (p fish. Infants of women in the highest quartile of fish oil intake (> or =1 tablespoon (11 ml)/day), consuming threefold the recommended dietary allowance of vitamin A and twofold that of vitamin D, were shorter (p = 0.036) and had a smaller head circumference (p = 0.003) than those of women consuming less. Infant size at birth increased with fish consumption, especially for women in the lower quartiles of consumption. Smaller birth size was linked to the highest levels of fish oil intake. Constituents of fish and fish oil might affect birth size differently depending on the amount consumed.

    We investigated the postnatal pattern of changes in adrenal size in very low-birth-weight (VLBW) infants and its relation to late-onset glucocorticoid-responsive circulatory collapse (LGCC) that may be associated with adrenal insufficiency. In 36 VLBW infants born at birth and unchanged at 3 weeks; group B (N = 24), the actual adrenal area was greater than or equal to the predicted value and decreased at 3 weeks; and group C (N = 6), the actual adrenal area was less than the predicted value and unchanged at 3 weeks. Five infants developed LGCC, and all five were in group A. These observations suggest that the life of the adrenal fetal zone might be extended beyond 3 weeks after birth in some VLBW infants and that prolonged fetal zone activity might correlate with LGCC. On the other hand, adrenal maturation might have already occurred at birth in some VLBW infants. Sonographic evaluation of adrenal size may enable prediction of subsequent LGCC in VLBW infants.

    Full Text Available Abstract Objective The aim of this study was to analyze the evolution from 1997 to 2009 of survival without significant (moderate and severe bronchopulmonary dysplasia (SWsBPD in extremely-low-birth-weight (ELBW infants and to determine the influence of changes in resuscitation, nutrition and mechanical ventilation on the survival rate. Study design In this study, 415 premature infants with birth weights below 1000 g (ELBW were divided into three chronological subgroups: 1997 to 2000 (n = 65, 2001 to 2005 (n = 178 and 2006 to 2009 (n = 172. Between 1997 and 2000, respiratory resuscitation in the delivery room was performed via a bag and mask (Ambu®, Ballerup, Sweden with 40-50% oxygen. If this procedure was not effective, oral endotracheal intubation was always performed. Pulse oximetry was never used. Starting on January 1, 2001, a change in the delivery room respiratory policy was established for ELBW infants. Oxygenation and heart rate were monitored using a pulse oximeter (Nellcor® attached to the newborn’s right hand. If resuscitation was required, ventilation was performed using a face mask, and intermittent positive pressure was controlled via a ventilator (Babylog2, Drägger. In 2001, a policy of aggressive nutrition was also initiated with the early provision of parenteral amino acids. We used standardized parenteral nutrition to feed ELBW infants during the first 12–24 hours of life. Lipids were given on the first day. The glucose concentration administered was increased by 1 mg/kg/minute each day until levels reached 8 mg/kg/minute. Enteral nutrition was started with trophic feeding of milk. In 2006, volume guarantee treatment was instituted and administered together with synchronized intermittent mandatory ventilation (SIMV + VG. The complications of prematurity were treated similarly throughout the study period. Patent ductus arteriosus was only treated when hemodynamically significant. Surgical closure of the

    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.

    Parenteral nutrition (PN) plays an important role in providing nutrients for infants unable to tolerate enteral feeds study was to look at PN prescribing in neonatal units in the United Kingdom (U.K.) and Ireland, in particular in infants < 1.5 kg. A postal questionnaire was administered to the 235 neonatal units. The response rate was 179 (76%), of which 136 (76%) used PN. The initial amount of protein prescribed was 0.1-2 g\\/kg\\/day in 102 units (91%), >2 g\\/kg\\/day in 4 (4%) and 5 (5%) used no protein. 88 (80%) started lipids with the first PN prescription. Only 5 units (5%) started with >1 g\\/kg\\/day. The maximum dose of lipids and protein both varied from 2 - >4 g\\/kg\\/day. The initial glucose infusion rate was 4-8 mg\\/kg\\/min. Interestingly only 44% of units started PN in the first 24 hours of age. Hence results show great variation in PN prescribing.

    We aimed to assess the relationship between the clinical and biochemical parameters of perfusion and superior vena cava (SVC) flow in a prospective observational cohort study of very low birth weight (VLBW) infants. Newborns with congenital heart disease were excluded. Echocardiographic evaluation of SVC flow was performed in the first 24 h of life. Capillary refill time (forehead, sternum and toe), mean blood pressure, urine output and serum lactate concentration were also measured simultaneously. Thirty-eight VLBW infants were examined. Eight patients (21%) had SVC flow less than 40 ml\\/kg\\/min. There was a poor correlation between the capillary refill time (in all sites), mean blood pressure, urine output and SVC flow. The correlation coefficient for the serum lactate concentration was r = -0.28, p = 0.15. The median serum lactate concentration was 3.5 (range 2.8-8.5) vs. 2.7 (range 1.2-6.9) mmol\\/l (p = 0.01) in low flow versus normal flow states. A serum lactate concentration of >2.8 was 100% sensitive and 60% specific for detecting a low flow state. Combining a capillary refill time of >4 s with a serum lactate concentration of >4 mmol\\/l had a specificity of 97% for detecting a low SVC flow state. Serum lactate concentrations are higher in low SVC flow states. A capillary refill time of >4 s combined with serum lactate concentrations >4 mmol\\/l increased the specificity and positive and negative predictive values of detecting a low SVC flow state.

    Full Text Available OBJECTIVE: To establish the influence of late-onset sepsis on neurodevelopment of preterm infants with very low birth weight (VLBW, according to the etiologic agent METHOD: This was a cohort of newborns with birth weight < 1,500 g and gestational age less than 32 weeks, admitted to the institutional intensive care unit (ICU with up to 48 hours of life, and followed-up at the outpatient follow-up clinic for preterm infants with VLBW until 2 years of corrected age. Exclusion criteria: death within the first 72 hours of life, congenital malformations and genetic syndromes, children with congenital infection by the human immunodeficiency virus (HIV, congenital infection (STORCH, presence of early-onset spesis and cases with more than one pathogen growth in blood cultures. Septic and non-septic infants were compared regarding neonatal outcomes and mortality. Neurodevelopment was assessed using the Bayley Scale (BSDI-II at 18 to 24 months of corrected age. RESULTS: 411 preterm infants with VLBW were eligible; the mean gestational age was 29 ± 2.2 weeks and mean birth weight was 1,041 ± 281grams. Late-onset sepsis occurred in 94 preterm infants with VLBW (22.8%. VLBW infants with Gram-positive infection showed motor deficit when compared to the non-septic group, 68.8% vs. 29.3%, respectively (OR 6; 1.6-21.8, p = 0.006; the cognitive development was similar between the groups. The overall mortality rate from infection was 26.7%; considering the pathogens, the rates were 18.7% for coagulase-negative Staphylococcus, 21.8% for Gram-positive bacteria, and 50% for Gram-negative bacteria and fungi. CONCLUSION: Neonatal sepsis has a significant influence on late neurodevelopment at 2 years of corrected age in preterm infants with VLBW, and Gram-positive infections are associated with motor deficit.

    This U.S.A.-based study examined the quantitative and qualitative characteristics of sleep, as well as the role of sleep, in the association of stress with depression, fatigue, and health-related quality of life (H-QOL) among mothers with a low-birth-weight, preterm infant in the neonatal intensive care unit at early postpartum. Fifty-five first-time mothers kept a sleep diary and filled out a battery of questionnaires. The wrist actigraphy method was also applied to collect information on maternal sleep. We tested a path model, with sleep disturbance and depression mediating the effect of stress on health-related well-being. Results showed that the majority of the study participants were stressed, depressed, fatigued, and at risk for poor physical and mental health. Poor sleep quality as perceived by mothers was significantly associated with their stress, fatigue, and poor mental and physical H-QOL. A cascading effect was found in the path model where maternal stress contributed to poor sleep quality and depression, which in turn contributed to poor mental H-QOL. In addition, poor sleep quality was associated with fatigue, which in turn contributed to poor physical and mental H-QOL. The underlying neurobiological mechanisms through which sleep affects the stress-health relation are discussed. The implications of sleep for intervention and prevention are also addressed.

    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

    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)....

    Full Text Available Abstract Background The evaluation of infant meconium as a cumulative matrix of prenatal toxicant exposure requires comparison to established biomarkers of prenatal exposure. Methods We calculated the frequency of detection and concentration of tobacco smoke metabolites measured in meconium (nicotine, cotinine, and trans-3'-hydroxycotinine concentrations and three serial serum cotinine concentrations taken during the latter two-thirds of pregnancy among 337 mother-infant dyads. We estimated the duration and intensity of prenatal tobacco smoke exposure using serial serum cotinine concentrations and calculated geometric mean meconium tobacco smoke metabolite concentrations according to prenatal exposure. We also compared the estimated associations between these prenatal biomarkers and infant birth weight using linear regression. Results We detected nicotine (80%, cotinine (69%, and trans-3'-hydroxycotinine (57% in most meconium samples. Meconium tobacco smoke metabolite concentrations were positively associated with serum cotinine concentrations and increased with the number of serum cotinine measurements consistent with secondhand or active tobacco smoke exposure. Like serum cotinine, meconium tobacco smoke metabolites were inversely associated with birth weight. Conclusions Meconium is a useful biological matrix for measuring prenatal tobacco smoke exposure and could be used in epidemiological studies that enroll women and infants at birth. Meconium holds promise as a biological matrix for measuring the intensity and duration of environmental toxicant exposure and future studies should validate the utility of meconium using other environmental toxicants.

    Background Late-onset sepsis (LOS) in very low-birth-weight (VLBW) infants is associated with significant morbidity and mortality. Objectives To determine the incidence of LOS workup, association, and predictive value of clinical indicators leading to culture-positive versus culture-negative sepsis workup. Methods All sepsis workups performed after 7 days of life, in neonates with birth weight of birth weight, corrected gestational age, and chronological age, at the time of workup. The clinical indicators leading to the performance of sepsis workup were compared between cases and controls. Results The incidence of culture-positive workup was 87/345 (25.2%) and that of LOS was 84/279 (30.1%). Among various clinical indicators, hypothermia and apnea were significantly associated with culture-positive sepsis workup (p = 0.015 and 0.004, respectively), with a positive predictive value of 81.2 and 71.4%, respectively. Conclusion In VLBW infants, one-fourth of sepsis workups resulted in a positive culture. Apnea and hypothermia were the most significant predictors of culture-positive workup after matching for GA, birth weight, chronological age, and corrected GA at the time of the workup.

    In Sweden the main exposure route for both polychlorinated biphenyls (PCB) and other persistent organochlorine compounds is through consumption of fatty fish species from the Baltic Sea (the eastern coast of Sweden). Cohorts of fishermen`s wives from the Swedish east and west coasts were established. Interviewed east and west coast cohort women ate locally caught fish at least twice as often as women from the general population. The east coast cohort women displayed during the period 1968-1989 an increased breast cancer incidence and mortality in ischemic heart disease as compared with the west coast cohort. Due to lack of individual data on exposure and confounding factors, it is not possible to conclude that the differences were caused by fish intake. Infants from the east coast cohort had during the period 1973-1991 an increased risk for low birth weight, as compared with infants from the west coast cohort. A nested case-referent study within the east coast cohort indicated an increased risk of low birth weight among infants born to mothers who reported a relatively high current intake of fish from the Baltic Sea, as well as among mothers who had grown up in a fishing village. Moreover, maternal 2,2`,4,4`,5,5`-hexachlorobiphenyl (CB-153, which was showed to be a feasible biomarker for exposure to PCB) concentrations in plasma drawn in 1995 and the estimated concentrations during the year of childbirth showed effects on the risk for having an infant with low birth weight. Employing alternative plausible kinetic models, an increased risk for low birth weight was observed at a CB-153 concentration in plasma during year of childbirth around 300-400 ng/g lipid. 117 refs, 5 figs, 4 tabs

    Full Text Available Abstract Objective: To evaluate factors associated with neonatal death within 24 hours after birth in very low birth weight preterm newborns. Methods: Prospective cohort of live births with gestational age of 230/7–316/7 weeks, birth weight of 500–1499g without malformations, in 19 public maternity hospitals in nine capitals in northeastern Brazil from July to December 2007. The 19 hospitals were assessed in relation to physical resources, equipment, human resources and aiming at quality in care initiatives. Hospital, maternal and neonatal characteristics, neonatal morbidity, neonatal procedures and interventions were compared between preterm newborns that died or survived up to 24 hours of life. The variables associated with death within 24 hours after birth were determined by logistic regression. Results: Of the 627 newborns enrolled in the study, 179 (29% died within 168 hours after birth, of which 59 (33% up to 24 hours and 97 (54% up to 48 hours after birth. The variables associated with death <24h were: weight <1000g (2.94; 1.32–6.53, 5th minute Apgar <7 (7.17; 3.46–14.88, male gender (2.99; 1.39–6.47. A better hospital structure was a protective factor for early neonatal death (odds ratio: 0.34; 95% confidence interval: 0.17–0.71. Conclusions: The high neonatal mortality on the first day of life in capital cities of Northeast Brazil is associated with biological variables such as weight and gender of the newborn, as well as low vitality at birth and a worse infrastructure of the hospital where the birth occurred.

Methods DR management protocols were surveyed in a prospective, questionnaire-based survey in 2008. Results were compared between countries and between academic and non-academic units. Protocols were compared to the 2005 ILCOR guidelines. Results In total, 190/249 units (76% replied. Protocols for DR management existed in 94% of units. Statistically significant differences between countries were found regarding provision of 24 hr in house neonatal service; presence of a designated resuscitation area; devices for respiratory support; use of pressure-controlled manual ventilation devices; volume control by respirator; and dosage of Surfactant. There were no statistically significant differences regarding application and monitoring of supplementary oxygen, or targeted saturation levels, or for the use of sustained inflations. Comparison of academic and non-academic hospitals showed no significant differences, apart from the targeted saturation levels (SpO2 at 10 min. of life. Comparison with ILCOR guidelines showed good adherence to the 2005 recommendations. Summary Delivery room management in German, Austrian and Swiss neonatal units was commonly based on written protocols. Only minor differences were found regarding the DR setup, devices used and the targeted ranges for SpO2 and FiO2. DR management was in good accordance with 2005 ILCOR guidelines, some units already incorporated evidence beyond the ILCOR statement into their routine practice.

    Perfluoroalkyl substances (PFAS) are ubiquitous, persistent chemicals that have been widely used in the production of common household and consumer goods for their nonflammable, lipophobic, and hydrophobic properties. Inverse associations between maternal or umbilical cord blood concentrations of perfluorooctanoic acid and perfluorooctanesulfonate and birth weight have been identified. This literature has primarily examined each PFAS individually without consideration of the potential influence of correlated exposures. Further, the association between PFAS exposures and indicators of metabolic function (i.e., leptin and adiponectin) has received limited attention. We examined associations between first-trimester maternal plasma PFAS concentrations and birth weight and cord blood concentrations of leptin and adiponectin using data on 1,705 mother-infant pairs from the Maternal Infant Research on Environmental Chemicals (MIREC) Study, a trans-Canada birth cohort study that recruited women between 2008 and 2011. Bayesian hierarchical models were used to quantify associations and calculate credible intervals. Maternal perfluorooctanoic acid concentrations were inversely associated with birth weight z score, though the null value was included in all credible intervals (log10 β = -0.10, 95% credible interval: -0.34, 0.13). All associations between maternal PFAS concentrations and cord blood adipocytokine concentrations were of small magnitude and centered around the null value. Follow-up in a cohort of children is required to determine how the observed associations manifest in childhood.

    Interventional radiology (IR) procedures in very low birth-weight (VLBW) infants (<1.5 kg) are challenging due to size, immaturity, comorbidities and lack of devices of suitable size. Infants are moved from the neonatal intensive care unit to the IR suite, further exposing them to risk. Our purpose was to review our experience of interventional procedures in VLBW infants, specifically complications and potential risks. VLBW infants referred for image-guided therapy between 1998 and 2005 were identified and medical records reviewed. ''Complications'' were divided into: major or minor, periprocedural or postprocedural, and intervention-/device-related, patient-related or equipment-related. Transport risk index of physiological stability (TRIPS) scores were calculated. A total of 116 infants (68 male, 48 female) underwent 176 procedures (159 vascular access-related and 17 nonvascular). Of 158 complications identified, 116 were major and 42 were minor. Major complications included hypothermia (n=33), line manipulations/removals (n=25), bleeding (n=12), thrombosis (n=4), cardiac arrest (n=3), tamponade (n=2), and multiorgan failure (n=1). Of the complications, 119 were categorized as intervention-/device-related, 32 patient-related and 7 equipment-related. There were no significant differences between pre- and postprocedural TRIPS scores. Successful completion of IR procedures in the VLBW infant is possible, but complications still occur in these fragile infants. (orig.)

    Recent nutritional research in very-low-birth-weight (VLBW) infants is focused on the prevention of protein malnutrition during the first postnatal weeks. At this early age, nutritional protein fortification depends on amino acid infusion via a central vein because of the immature gastrointestinal tract. In 2010 new guidelines on nutrition were proposed by the European Society of Paediatric Gastroenterology, Hepatology, and Nutrition nutrition committee. In particular, the relative increase in the protein fraction in the nutrition of these infants aims to prevent early postnatal weight loss, to prevent morbidity, and to stimulate neurodevelopment. On the other hand, an increasing number of follow-up studies in VLBW infants indicate that, in particular, those infants who show rapid growth after preterm birth are at risk of metabolic consequences and cardiovascular disease later in life. In this review, we describe the quest to develop a customized diet that offers optimal nutrition at several time points of growth and development during the first year of life. This diet should prevent early malnutrition, enhance neurodevelopment, and limit the increase in total body fat during the first 6 mo. We question whether one type of early diet suffices for normal neurodevelopment with a normal body composition in later life or whether we need several types of diet at various stages of development.

Fifty preterm infants less than 37 weeks with weight less than 1500 g were enrolled in the study. They received parental nutrition and feeding according to our protocol. When enteral feeding reached 100 cc/kg/day, infants were randomized into two groups: group I, Cases, n=25, where post discharge formula (PDF was used for fortification, group II, Controls, n=25 with no fortification. Infants of both groups were given 50% of required enteral feeding as premature formula. This protocol was used until infants’ weight reached 1800 g. Daily weight, weekly length and head circumference were recorded. Hemoglobin, albumin (Alb, electrolytes, blood urea nitrogen (BUN and clinical complications were documented. Human milk fortification with PDF resulted in better growth with increase in weight 16.8 and 13.78 g/kg/day (P=0.0430, length 0.76 and 0.58 cm/week (P=0.0027, and head circumference of 0.59 and 0.5 cm/week (P=0.0217 in cases and controls respectively. Duration of hospital stay was less in cases (22.76 versus 28.52 days in Controls, P=0.02. No significant changes were found in serum electrolytes, BUN, or Alb between both groups. Hemoglobin was significantly higher in Cases, P=0.04. There were no significant clinical complications. Our feeding protocol of fortification of human milk with PDF in preterm very low birth weight newborns resulted in better growth and decrease in length of hospital stay. The use of PDF could be an alternative option for fortification of mothers’ milk for preterm VLBW infants in developing countries with low resources.

    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.].

    Late-onset bloodstream infection (LOBI) is a significant problem in very low-birth-weight (VLBW) infants and can lead to increased mortality and morbidity. The incidence of LOBI in VLBW infants in our unit was >35% before 2004, much higher than 20% reported in other studies. A comprehensive infection control measure was introduced in our unit in 2005. Here we report the effects of comprehensive infection control measures on the rate of LOBI in VLBW infants. Infants in the preintervention group (born 2001 to 2004) were compared with the intervention group (born 2005 to 2008) for baseline demographics, risk factors for infection, and the rate of LOBI. LOBI was defined as a positive blood and/or cerebrospinal fluid culture after 3 days of life. Three hundred thirty-four VLBW infants were admitted to our unit during the preintervention period and 303 during the intervention period. There was no significant difference in baseline demographics and risk factors for LOBI between the two groups. The incidence of LOBI was significantly reduced from 38% before intervention to 23% after intervention ( P control measures significantly reduced the rate of LOBI in VLBW infants.

    Full Text Available OBJECTIVES: In preterm infants, postnatal myocardial adaptation may be complicated by bronchopulmonary dysplasia (BPD. We aimed to describe the development of left ventricular function by serial 2D, Doppler, and speckle tracking echocardiography (2D-STE in infants with and without BPD during the neonatal period and compare these to anthropometric and conventional hemodynamic parameters. STUDY DESIGN: Prospective echocardiography on day of life (DOL 1, 7, 14, and 28 in 119 preterm infants 10% were seen for the apical segment. While anthropometric parameters show rapid development during the first 4 weeks of life, the speckle tracking parameters did not differ statistically significantly during the neonatal period. Infants with and without BPD differed significantly (p<0.001 in the development of anthropometric parameters, conventional hemodynamic parameters except for heart rate, and 2D-STE parameters: global longitudinal systolic strain rate (GLSSR and longitudinal systolic strain for the mid left wall (LSSR. The largest differences were seen at DOL 1 and 7 in GLSSR (p<0.001 and in LSSR (p<0.01. CONCLUSIONS: Reproducible 2D-STE measurements are possible in preterm infants <1500 g. Cardiac deformation reveals early (DOL 1 and 7 ventricular changes (GLSSR and LSSR in very low birth weight infants who develop BPD.

In this non-randomized study, we aimed to determine the effect of administration of live OLB6378 on infants’ humoral immunity. Secondly, we tried to elucidate whether similar effects would be observed with administration of non-live OLB6378. Low birth weight (LBW infants weighing 1500–2500 g were divided into three groups: Group N (no intervention, Group L (administered live OLB6378 concentrate, and Group H (administered non-live OLB6378 concentrate. The interventions were started within 48 h after birth and continued until six months of age. Serum immunoglobulin G (IgG levels (IgG at one month/IgG at birth were significantly higher in Group L than in Group N (p < 0.01. Group H exhibited significantly higher serum IgG levels (p < 0.01 at one month of age and significantly higher intestinal secretory immunoglobulin A (SIgA levels (p < 0.05 at one and two months of age than Group N. No difference was observed in the mortality or morbidity between groups. Thus, OLB6378 administration in LBW infants enhanced humoral immunity, and non-live OLB6378, which is more useful as a food ingredient, showed a more marked effect than the viable bacteria.

FONTES DOS DADOS: Para essa revisão, pesquisas foram feitas na MEDLINE (1996 a outubro de 2004, no Cochrane Database, em resumos da Society for Pediatric Research e recentes conferências sobre o tema. SÍNTESE DOS DADOS: A tecnologia e os novos conhecimentos científicos têm aumentado significantemente a sobrevida de prematuros extremos. Esse aumento da sobrevida resultou em aumento da incidência de displasia broncopulmonar. Atualmente, a displasia broncopulmonar é mais freqüentemente observada em recém-nascidos OBJECTIVE: To review the main causes of new bronchopulmonary dysplasia and the strategies utilized to decrease its incidence in extremely low birth weight infants. DATA SOURCES: For this review a MEDLINE search from 1966 to October 2004, the Cochrane Database, abstracts from the Society for Pediatric Research and recent meetings on the topic were used. SUMMARY OF FINDINGS: The survival of extremely low birth weight infants has increased significantly due to improvement in both scientific knowledge and technology. This improvement in survival has therefore resulted in an increased incidence of bronchopulmonary dysplasia. The characteristics of bronchopulmonary dysplasia in extremely low birth weight infants, the so called "new" bronchopulmonary dysplasia are quite different from the classic bronchopulmonary dysplasia described by Northway. This new bronchopulmonary dysplasia has a multifactorial etiology, which includes volutrauma, atelectrauma, oxygen toxicity and lung inflammation. Therapy such as prenatal corticosteroids, exogenous surfactant, nasal continuous positive airway pressure, new mechanical ventilation modalities and gentle ventilation have been used in attempts to decrease lung injury severity.

    2004-09-01

    Full Text Available Abstract Background Enteral feeding of very low birth weight (VLBW infants is a challenge, since metabolic demands are high and administration of enteral nutrition is limited by immaturity of the gastrointestinal tract. The amino acid glutamine plays an important role in maintaining functional integrity of the gut. In addition, glutamine is utilised at a high rate by cells of the immune system. In critically ill patients, glutamine is considered a conditionally essential amino acid. VLBW infants may be especially susceptible to glutamine depletion as nutritional supply of glutamine is limited in the first weeks after birth. Glutamine depletion has negative effects on functional integrity of the gut and leads to immunosuppression. This double-blind randomised controlled trial is designed to investigate the effect of glutamine-enriched enteral nutrition on feeding tolerance, infectious morbidity and short-term outcome in VLBW infants. Furthermore, an attempt is made to elucidate the role of glutamine in postnatal adaptation of the gut and modulation of the immune response. Methods VLBW infants (gestational age

    Rapid early growth is associated with adverse metabolic outcome. The aim of this study was to determine whether there are differences in body composition (BC) between very-low-birth-weight preterm (VLBWPT) infants born appropriate for gestational age (AGA) and small for gestational age (SGA) and whether these differences relate to first-year growth. Twenty-six VLBWPT (15 AGA and 11 SGA). The BC was analyzed by dual X-ray absorptiometry at 2 years, and insulin-like growth factors (IGFs) I and II and leptin were administered weekly for 8 weeks and at 1, 3, 6, and 12 months. At 24 months, the VLBW SGA infants were lighter and had less peripheral fat and lean mass than VLBW AGA infants. In all patients, the percentage of fat mass correlated inversely with the change in weight [standard deviation scores (SDS)] from newborn to 2 and 4 weeks and the 1-month leptin and lean mass (SDS) correlated inversely with the change in weight (SDS) from newborn to 2, 4, and 8 weeks and with 4-week IGF-I and 8-week IGF-II. Lean mass (SDS) inversely correlated with 6-month IGF-I and directly correlated with 1-week and 3-month IGF-I in SGA VLBW infants only. A longer follow-up period will show whether additional differences will develop later.

    Summary Background Salivary cortisol measurement is a non-invasive method suitable for use in neonatal research. Mother-infant separation after birth represents stress and skin-to-skin contact (SSC) has numerous benefits. The aim of the study was to measure salivary cortisol in mothers and newborns before and after SSC in order to assess the effect of SSC on mothers’ and infants’ stress and to estimate the efficacy of collecting small saliva samples in newborns. Methods Salivary cortisol was measured in 35 mother-infant pairs before and after the first and the fifth SSC in small saliva samples (50 μL) using the high sensitivity Quantitative ELISA-Kit (0.0828 nmol/L) for low cortisol levels detection. Samples were collected with eye sponge during 3 to 5 minutes. Results Cortisol level in mothers decreased after SSC: the highest levels were measured before and the lowest after SSC and the differences in values were significant during both the first (pcortisol level decrease was detected in 14 (40%) and an increase in 21 (60%) newborns, and during the fifth SSC a decrease was detected in 16 (45.7%) and an increase in 19 (54.3%) newborns, without confirmed significance of the difference. Saliva sampling efficacy using eye sponge was 75%. Conclusions Cortisol level decrease in mothers proves the stress reduction during SSC, while variable cortisol levels in infants do not indicate stress reduction and imply the need for further research. The used sampling method appeared to be one of the most optimal considering the sample volume, sampling time and efficacy.

    Full Text Available Abstract Background The ACE gene contains a polymorphism consisting of either the presence (insertion, I or absence (deletion, D of a 287 bp alu repeat in intron 16. The D allele is associated with increased ACE activity in both tissue and plasma. The DD genotype is associated with risk of developing ARDS and mortality. The frequency of the D allele is higher in patients with pulmonary fibrosis, sarcoidosis and berylliosis. The role of this polymorphism has not been studied in the development of BPD in the premature newborn. Methods ACE I/D genotype was determined in 245 (194 African-American, 47 Caucasian and 4 Hispanic mechanically ventilated infants weighing less than 1250 grams at birth and compared to outcome (death and/or development of BPD. Results The incidence of the D allele in the study population was 0.58. Eighty-eight (35.9% infants were homozygous DD, 107 (43.7% were heterozygous ID and 50 (20.4% were homozygous II. There were no significant differences between genotype groups with respect to ethnic origin, birth weight, gestation, or gender. There was no effect of the ACE I/D polymorphism on mortality or development of BPD (O2 on 28 days or 36 weeks PCA. Secondary outcomes (intraventricular hemorrhage and periventricular leukomalacia similarly were not influenced by the ACE ID polymorphism. Conclusions The ACE I/D polymorphism does not significantly influence the development of BPD in ventilated infants less than 1250 grams.

    OBJECTIVE Hydrocephalus treatment in extremely low-birth-weight (ELBW) infants still represents a challenge for the pediatric neurosurgeon, particularly when the patient weighs far less than 1000 g. In such cases, the benefits in terms of neurological outcome following early treatment do not always outweigh the surgical risks, especially considering the great difference in the surgical risk before patient weight increases. To assess the efficacy and reliability of a percutaneous-tunneled, transfontanellar external ventricular drain (PTTEVD) in ELBW infants, the authors started a new protocol for the early surgical treatment of hydrocephalus. METHODS Ten cases of posthemorrhagic hydrocephalus (PHH) in ELBW infants (5 cases hydrocephalus was achieved. One patient had a single episode of CSF leakage (due to insufficient CSF removal). In another patient Enterococcus in the CSF sample was detected the day after abdominal surgery with ileostomy (infection resolved with intrathecal vancomycin). One patient died of Streptococcus sepsis, a systemic infection existing prior to drain placement that never resolved. One patient had Pseudomonas aeruginosa sepsis prior to drain insertion; a PTTEVD was implanted, the infection resolved, and the hydrocephalus was treated in the same way as with a traditional EVD, while the advantages of a quick, minimally invasive, bedside procedure were maintained. Once a patient reached 1 kg in weight, when necessary, a ventriculoperitoneal shunt was implanted and the PTTEVD was removed. CONCLUSIONS The introduction of PTTEVD placement in our standard protocol for the management of PHH has proved to be a wise option for small patients.

    Full Text Available Abstract Background Studies in adult intensive care have highlighted the importance of insulin and improved glucose control on survival, with 32% reduction in mortality, 22% reduction in intensive care stay and halving of the incidence of bacteraemia. Very low birth weight infants requiring intensive care also have relative insulin deficiency often leading to hyperglycaemia during the first week of life. The physiological influences on insulin secretion and sensitivity, and the potential importance of glucose control at this time are not well established. However there is increasing evidence that the early postnatal period is critical for pancreatic development. At this time a complex set of signals appears to influence pancreatic development and β cell survival. This has implications both in terms of acute glucose control but also relative insulin deficiency is likely to play a role in poor postnatal growth, which has been associated with later motor and cognitive impairment, and fewer β cells are linked to risk of type 2 diabetes later in life.

    The aim of this study was to determine the effect of human milk feeding during NICU hospitalization on neurodevelopment at 24 months of corrected age in very low birth weight infants. A cohort of 316 very low birth weight newborns (weight ≤ 1500 g) was prospectively enrolled in a follow-up program on admission to the Neonatal Intensive Care Unit of S. Orsola Hospital, Bologna, Italy, from January 2005 to June 2011. Neurodevelopment was evaluated at 24 months corrected age using the Griffiths Mental Development Scale. The effect of human milk nutrition on neurodevelopment was first investigated using a multiple linear regression model, to adjust for the effects of gestational age, small for gestational age, complications at birth and during hospitalization, growth restriction at discharge and socio-economic status. Path analysis was then used to refine the multiple regression model, taking into account the relationships among predictors and their temporal sequence. Human milk feeding during NICU hospitalization and higher socio-economic status were associated with better neurodevelopment at 24 months in both models. In the path analysis model intraventricular hemorrhage-periventricular leukomalacia and growth restriction at discharge proved to be directly and independently associated with poorer neurodevelopment. Gestational age and growth restriction at birth had indirect significant effects on neurodevelopment, which were mediated by complications that occurred at birth and during hospitalization, growth restriction at discharge and type of feeding. In conclusion, our findings suggest that mother's human milk feeding during hospitalization can be encouraged because it may improve neurodevelopment at 24 months corrected age.

    Full Text Available Percutaneously inserted central catheters (PICCs are often used in neonatal medicine. Venous thrombosis (VT is one of the complications associated with PICC use. According to some reports, fresh frozen plasma (FFP may be a risk factor for VT. The purpose of this study was to determine whether FFP use is associated with VT in extremely low birth weight infants (ELBWIs. We performed a matched case-control study on risk factors for VT in ELBWIs born over a period of 5 years in the neonatal intensive care unit of a tertiary hospital. Controls were infants from the unit matched for gestational age and birth weight. We performed univariate analyses and created receiver operating characteristic (ROC curves for the cut-off values of continuous parameters such as FFP. We also conducted multivariate conditional logistic regression analysis and calculated adjusted odds ratios and their 95% confidence intervals. Thirteen VT cases and 34 matched controls were examined. Using an ROC curve, FFP by day 5>50mL/kg was selected as the cut-off value. In multivariate conditional logistic regression analysis, FFP by day 5>50mL/kg exhibited an adjusted odds ratio of 5.88 (95% confidence interval:1.12-41.81, p=0.036. FFP by day 5>50mL/kg may be a risk factor for VT in ELBWIs.

    Full Text Available CONTEXT: Central diabetes insipidus (CDI is a rare cause of hypernatremia during the neonatal period. The diagnosis is particularly difficult in very low birth weight (VLBW newborns. CASE REPORT: We report on a preterm newborn who presented CDI soon after birth. On the third day of life, signs of dehydration were present despite normal fluid supply. The diuresis rate was 4.4 ml/kg/h. Although the fluid supply was then increased, the dehydration continued, with hypernatremia, normal glycemia, diuresis of 7.4 ml/kg/h and urine density of 1005 mOsmol/l. Thus, a diagnostic hypothesis of diabetes insipidus was raised. A test with a nasal vasopressin analogue (dDAVP was performed and CDI was confirmed. Reduction of the fluid supply became possible through appropriate treatment. CONCLUSION: The diagnosis of CDI is rarely made during the neonatal period, especially in VLBW newborns, because of the difficulty in detecting elevated diuresis. Persistent hypernatremia, usually accompanied by hyperthermia despite abundant fluid supply, weight loss and low urine osmolality are important signs of alert.

    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.

    In recent years, despite of significant progress in the treatment of premature infants with extremely low body weight, still a significant problem remains severe, treatment-resistant generalized infections among which the percentage of fungal infections is increasing. The invasive candidiasis, especially caused by non-albicans species of Candida, are of particular importance. In the case of resistance on fluconazole and amphotericin B the use of echinocandin drug may be a useful choice. This paper reviews the pharmacokinetics of caspofungin in neonates and children, as well as the case reports and clinical trials on the use of caspofungin in neonates, including the premature infants. We describe also the premature neonate with low birth weight and a generalized infection caused by Candida glabrata, where, despite of the treatment based on the sensitivity of the fungus it did not achieve clinical improvement and sterilization of cultures. It was not until the lead-in of caspofungin in dose 2 mg/kg/day allowed to cure the patient. There was a transient increase in the activity of aminotransferases and level of bilirubin as a complication of treatment. At the end of application of caspofungin the liver functions have been slowly normalized. Caspofungin appeared to be effective in the treatment of systemic fungal C. glabrata in premature neonate with extremely low birth weight. Echinocandins, including caspofungin, appear to be a promising alternative to previously used agents in the treatment of invasive Candida infections in newborns. However, the further randomized trials on the use of caspofungin in preterm neonates, regarding long term follow-up, should be undertaken.

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.

    Full Text Available This research aimed to realize the spacial distribution of the infant mortality rates and of the proportion of low weight newborns in the southern area of Brazil and to test the association of those indicators with socioeconomic factors and health services. It is an ecological study put together from data collected from the 1,159 municipalities comprising the southern area of Brazil in the year 2000. The independent variables were the Municipal Human Development Rate, the illiteracy rate, the Gini coefficient, the proportion of poor people and people in homes with indoor plumbing and bathrooms, the annual average of medical visits for basic medical specialties, the monthly average of home visits per family and the number of medical clinics per 10,000 inhabitants. Kolmogorov-Smirnov, ANOVA and Kruskall-Wallis tests were performed and the Spearman coefficient of correlation was calculated. A significant statistical association was established between infant mortality and all the socioeconomic indicators. As for the proportion of low birth weight, it was associated with the proportion of people in homes with indoor plumbing and bathrooms, the annual average of medical visits for basic medical specialties, the Gini coefficient, poverty levels and monthly average of home visits per family. The spacial distribution of the diseases investigated allowed the identification of areas with the worst indicators investigated and which need greater government investment and attention. The public policies in infant health care should consider the need to improve the socioeconomic conditions and accessible health services in order to reduce the inequalities in health and the magnitude of the disease.

    Background. Chronic lung disease (CLD) in premature infants shows a variable clinical course with different radiological manifestations. Objective. To evaluate the correlation between parameters of transmembrane permeability [albumin/secretory component (SC)] and oxidative stress [malondialdehyde (MDA)/SC] in tracheal aspirate fluid (TAF) and radiological findings with the effect of a 5-day course of dexamethasone (0.5 mg/kg per day). Materials and methods. Fifty ventilator-dependent premature infants with birth weights < 1,500 g (gestational ages 23-31 weeks) and radiological signs of early chronic lung disease (CLD) were treated with dexamethasone at day of life 5-27 (median 10 days) because of respiratory deterioration. TAF was collected serially. Chest X-rays taken before and 8-10 days after dexamethasone were scored for changes of opacification, consolidation and hyperinflation/emphysema, and classified into three groups. Results. Twenty-four infants had a positive response to dexamethasone, defined as a reduction of the ventilation index FiO{sub 2} x mean airway pressure > 40 % at day 5, compared to pretreatment values. About 80 % of the responders showed homogeneous lung opacification on chest X-ray, reflecting leaky lung syndrome. In contrast, seven of eight infants with predominantly emphysema on radiology were non-responders; 80 % of infants with a mixed radiological picture characterized by predominance of consolidations alternating with regions of emphysema were also non-responders. Ratios of albumin/SC and MDA/SC in TAF decreased significantly within 3 days after the onset of dexamethasone. However, MDA/SC was persistently higher in non-responders compared to responders. Opaque lungs were largely improved by dexamethasone, in contrast to streaky or patchy consolidations and emphysema. In a logistic regression model, radiographic classification was the most important factor influencing the response to dexamethasone with a positive predictive value of 86

    Full Text Available BACKGROUND: Serial C-reactive protein (CRP values may be useful for decision-making regarding duration of antibiotics in neonates. However, established standard of practice for its use in preterm very low birth weight (<1500 g, VLBW infants are lacking. OBJECTIVE: Evaluate compliance with a CRP-guided computerized decision support (CDS algorithm and compare characteristics and outcomes of compliant versus non-compliant cases. Measure correlation between CRPs and white blood count (WBC indices. METHODS: We examined 3 populations: 1 all preterm VLBW infants born at Vanderbilt 2006-2011 - we assessed provider compliance with CDS algorithm and measured relevant outcomes; 2 all patients with positive blood culture results admitted to the Vanderbilt NICU 2006-2012 - we tested the correlation between CRP and WBC results within 7 days of blood culture phlebotomy; 3 1,000 randomly selected patients out of the 7,062 patients admitted to the NICU 2006-2012 - we correlated time-associated CRP values and absolute neutrophil counts. RESULTS: Of 636 VLBW infants in cohort 1, 569 (89% received empiric antibiotics for suspected early-onset sepsis. In 409 infants (72% the CDS algorithm was followed; antibiotics were discontinued ≤48 hours in 311 (55% with normal serial CRPs and continued in 98 (17% with positive CRPs, resulting in significant reduction in antibiotic exposure (p<0.001 without increase in complications or subsequent infections. One hundred sixty (28% were considered non-compliant because antibiotics were continued beyond 48 hours despite negative serial CRPs and blood cultures. Serial CRPs remained negative in 38 (12% of 308 blood culture-positive infants from cohort 2, but only 4 patients had clinically probable sepsis with single organisms and no immunodeficiency besides extreme prematurity. Leukopenia of any cell type was not linked with CRPs in cohorts 2 and 3. CONCLUSIONS: CDS/CRP-guided antibiotic use is safe and effective in culture

    Full Text Available OBJECTIVES: To investigate the early determinants of overweight and obesity status at age two years. METHODS: A total of 1098 healthy neonates (563 boys and 535 girls were involved in this community-based prospective study in China. Data on body weight and length were collected at birth, the 3(rd and 24(th month. A self-administered questionnaire was used to collect data on social demography and feeding patterns of children, etc. Three multivariable logistic regression models were employed to make various comparisons of weight status, i.e., model 1 (obesity vs. non-obesity, model 2 (combined overweight and obesity vs. normal weight, and model 3 (obesity, overweight and normal weight. RESULTS: Prevalences of overweight/obesity (95(th >BMI ≥85(th p and BMI ≥95(th p, referring to WHO BMI standards at 2 years of age are 15.8%/11.2% for boys and 12.9%/9.0% for girls, respectively. Being born with macrosomia (OR: 1.80-1.88, relatively greater BMI increment in the first 3 months (OR: 1.15-1.16 and bottle emptying by encouragement at age two (OR: 1.30-1.57 were found in all three models to be significant risk factors for higher BMI status at 2 years. Pre-pregnancy maternal BMI (OR: 1.09-1.12, paternal BMI (OR: 1.06, and mixed breastfeeding (OR: 1.54-1.57 or formula feeding (OR: 1.90-1.93 in the first month were identified as significant in models 2 and 3. Child-initiated bottle emptying at age two was observed to increase the risk of obesity by 1.31 times but only in model 1. CONCLUSION: Fetal and early postnatal growth and feeding pattern appear to have significant impacts on early childhood overweight and obesity status independent of parental BMI. Policy-based and multidisciplinary approaches to promote breastfeeding and enhancement of feeding skills of care takers may be promising intervention strategies.

    Full Text Available Technology advances and scientific studies in Neonatal Intensive Care Units (NICU have contributed significantly to reduce mortality and morbidity of at-risk newborns (NB. However, they are more likely to present neurological and/or developmental psychomotor delay with neurological and sensory alterations. Therefore, proposals for neonatal intervention were developed with the aim of protecting the baby and offering appropriate incentives to minimize the effects of hospital intervention. To this end, programs of protective measures such as the Kangaroo Mother Care (KMC were developed. Given the relevance of the issue described, this systematic review critically appraises articles from the national and international literature, published in recent years (from 2000 to 2011, that describe whether the KMC can be a protective factor for the development of writing in premature infants. The textual search was conducted using the Virtual Health Library (VHL, a website that covers publications worldwide, allowing access to articles from health science, including LILACS, IBECS, MEDLINE, Cochrane Library and SciELO, as database. The findings revealed that infants who participated in the KMC program showed improvements in their development and that factors such as low-birth-weight prematurity and learning disorders have close relationship with the onset of motor impairments and changes in psychomotor development. The findings showed no articles describing the KMC as a protective factor for the incidence of dysgraphia. Thus, we emphasize the importance of conducting further studies on these topics.

    Background The circulating neutrophil count was commonly believed to be influenced by altitude. At present, neutrophil reference ranges (RRs) for very low birth weight (VLBW) neonates are only available from the sea level and from high altitude. This study aimed to construct RRs for neutrophils in VLBW infants in an intermediate-altitude area and assess its usefulness in evaluation for sepsis. Methods This was a multicenter retrospective study of 2173 VLBW infants admitted to 20 hospitals in Chongqing in southwest of China with altitude from 1000 to 2600 feet. The RRs for absolute total neutrophils (ATN), absolute total immature neutrophils (ATI), and immature: total neutrophil proportion were constructed based on “normal” neonates (unlikely infection). Values of neutrophil from septic and uninfected neonates were respectively assessed using the revised RRs and the previous Mouzinho’s and Schmutz’s RRs. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were compared using the McNemar’s test or χ2 test. Results The upper limits for ATN and ATI using the revised RRs were much higher than those using Mouzinho’s RRs, but lower than those using Schmutz’s RRs. The revised RRs and Mouzinho’s RRs had higher sensitivities than Schmutz’s RRs at 73–672 h. The revised RRs had a higher specificity than Mouzinho’s RRs at both 0–72 h and 73–672 h. The NPV for any abnormality in neutrophil values was high at both 0–72 h and 73–672 h irrespective of the RRs used. Conclusion Altitude-appropriate RRs for neutrophils is more suitable to guide the diagnosis and management of neonatal sepsis in VLBW infants. PMID:28182674

DESIGN AND SETTING: Prospective study in the nursery attached to the Maternity Ward of the "Prof. Pedro de Alcântara" Children's Institute, Hospital das Clínicas, Department of Pediatrics, Faculdade de Medicina da Universidade de São Paulo, Brazil. METHODS: Seventy-two VLBW infants (mean protein intake = 3.7 mg/kg/day were enrolled in a prospective cohort study in two groups: AGA (n = 34 and SGA (n = 38. Blood samples, six-hour urine (6hUr collections and urine sample tests (STUr were obtained for urea and creatinine assays at three and five weeks of life. Statistical analysis: Student's t test, Pearson correlation and linear regression (p < 0.05. RESULTS: There were no differences between groups for serum urea, 6hUr and STUr, or between two assessments within each group. Serum urea correlated with 6hUr in both AGA and SGA, and to STUr in SGA; 6hUr correlated with STUr in both AGA and SGA. There was no correlation between protein intake and serum or urine urea. CONCLUSIONS: Serum and urinary urea did not reflect protein intake when mean intakes of 3.7 g/kg/day were used. Sample tests of urinary urea can be as reliable as urea from urine collected over longer periods.

    Full Text Available INTRODUCTION: We evaluated blood culture-proven sepsis episodes occurring in microclusters in very-low-birth-weight infants born in the German Neonatal Network (GNN during 2009-2010. METHODS: Thirty-seven centers participated in GNN; 23 centers enrolled ≥50 VLBW infants in the study period. Data quality was approved by on-site monitoring. Microclusters of sepsis were defined as occurrence of at least two blood-culture proven sepsis events in different patients of one center within 3 months with the same bacterial species. For microcluster analysis, we selected sepsis episodes with typically cross-transmitted bacteria of high clinical significance including gram-negative rods and Enterococcus spp. RESULTS: In our cohort, 12/2110 (0.6% infants were documented with an early-onset sepsis and 235 late-onset sepsis episodes (≥72 h of age occurred in 203/2110 (9.6% VLBW infants. In 182/235 (77.4% late-onset sepsis episodes gram-positive bacteria were documented, while coagulase negative staphylococci were found to be the most predominant pathogens (48.5%, 95%CI: 42.01-55.01. Candida spp. and gram-negative bacilli caused 10/235 (4.3%, 95%CI: 1.68% -6.83% and 43/235 (18.5% late-onset sepsis episodes, respectively. Eleven microclusters of blood-culture proven sepsis were detected in 7 hospitals involving a total 26 infants. 16/26 cluster patients suffered from Klebsiella spp. sepsis. The median time interval between the first patient's Klebsiella spp. sepsis and cluster cases was 14.1 days (interquartile range: 1-27 days. First patients in the cluster, their linked cases and sporadic sepsis events did not show significant differences in short term outcome parameters. DISCUSSION: Microclusters of infection are an important phenomenon for late-onset sepsis. Most gram-negative cluster infections occur within 30 days after the first patient was diagnosed and Klebsiella spp. play a major role. It is essential to monitor epidemic microclusters of sepsis in

    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 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.

    Invasive disseminated neonatal aspergillosis is an uncommon disease, with only scattered reports in literature in the last few years. Here we report on a 25-week gestational age, 730 g at birth preterm female infant who developed on day-of-life 10 multiple cutaneous exhulcerative lesions in her right arm, trunk and abdomen. Early recognition and diagnosis of these lesions as a due to cutaneous initial symptom of cutaneous disseminated aspergillosis, as well as prompt treatment with Liposomal amphotericin B + Itraconazole, secured successful recovery from the systemic infection. Skin lesions healed without any surgical treatment. The infant was discharged in good health. Long-term follow-up at three years of age revealed normality of all neurodevelopmental and cognitive parameters. To our knowledge, this is one of the very few cases of survival, free from sequelae, for a preterm infant affected by neonatal cutaneous disseminated aspergillosis.

    【Objective】 To investigate the extremely low birth weight infant's (ELBWI) quality of life and related intervention measures through review of ELBWI's living condition from a single centre NICU in recently years. 【Method】 It was retrospectively analyzed about the clinical data of 32 patients of ELBWI from February 2000 to January 2012. 【Results】 The ELBWI suvival rate, mortality rate, abandon rate were 34. 4%, 25. 0%,and 40. 6% respectively. The Assisted Reproductive Technologies (ART) ELBWI suvival rate was 75. 0%. Female suvival rate(72. 7%) was higer than male's in all suvival patients. The common direct causes of death were pulmonary haemorrhage (62. 5%), hyaline membrane disease (12. 5%),intracranial haemorrhage(12. 5%) and gastrointestinal bleeding(12. 5%). The data were divided into two stages (February 2000~January 2006 vs February 2006~January 2012). Compared with the former group,the abandon rate of the later was obviously lower(28. 0% vs 85. 7%) and suvival rate was significantly higher (44% vs 0%). There was significant diffrence of ART between survival group and mortality/abandon group(P<0. 05) with single factor analysis and logistic regression analysis.【Conclusion】 Positive treatment and timely processing of complications can improve ELBWI survival rate and reduce mortality.

    Full Text Available BACKGROUND: Overweight/obesity in women of childbearing age is a serious public-health problem. In China, the incidence of maternal overweight/obesity has been increasing. However, there is not a meta-analysis to determine if pre-pregnancy body mass index (BMI is related to infant birth weight (BW and offspring overweight/obesity. METHODS: Three electronic bibliographic databases (MEDLINE, EMBASE and CINAHL were searched systematically from January 1970 to November 2012. The dichotomous data on pre-pregnancy overweight/obesity and BW or offspring overweight/obesity were extracted. Summary statistics (odds ratios, ORs were used by Review Manager, version 5.1.7. RESULTS: After screening 665 citations from three electronic databases, we included 45 studies (most of high or medium quality. Compared with normal-weight mothers, pre-pregnancy underweight increased the risk of small for gestational age (SGA (odds ratios [OR], 1.81; 95% confidence interval [CI], 1.76-1.87; low BW (OR, 1.47; 95% CI, 1.27-1.71. Pre-pregnancy overweight/obesity increased the risk of being large for gestational age (LGA (OR, 1.53; 95% CI, 1.44-1.63; and OR, 2.08; 95% CI; 1.95-2.23, high BW (OR, 1.53; 95% CI, 1.44-1.63; and OR, 2.00; 95% CI; 1.84-2.18, macrosomia (OR, 1.67; 95% CI, 1.42-1.97; and OR, 3.23; 95% CI, 2.39-4.37, and subsequent offspring overweight/obesity (OR, 1.95; 95% CI, 1.77-2.13; and OR, 3.06; 95% CI, 2.68-3.49, respectively. Sensitivity analyses revealed that sample size, study method, quality grade of study, source of pre-pregnancy BMI or BW had a strong impact on the association between pre-pregnancy obesity and LGA. No significant evidence of publication bias was observed. CONCLUSIONS: Pre-pregnancy underweight increases the risk of SGA and LBW; pre-pregnancy overweight/obesity increases the risk of LGA, HBW, macrosomia, and subsequent offspring overweight/obesity.

    近年来,初乳对于新生儿尤其是早产儿的免疫保护作用越来越为人们所熟知。但是极低出生体重儿由于自身疾病和吞咽乏力等原因早期不能经口喂养,降低了初乳对新生儿的免疫保护作用。为使极低出生体重儿早期即得到来自初乳的保护,有学者提出早期使用初乳对极低出生体重儿进行口腔涂抹。本文将围绕初乳口腔涂抹的理论基础、初乳口腔涂抹的安全性、可行性、操作标准及效果等4个方面进行探讨。%In recent years, more and more people were familiar with the immune protective effect of colostrum on newborn infants, especially on premature infants. But for very low birth weight infants, due to their own disease andimmature, they couldn′t be fed by oral in the early days of life, which reduced the immune protective effect of colostrum on the newborns. In order to make the very low birth weight infants get the protection, some scholarsput forward the earlyoropharyngeal administration of colostrum for very low birth weight infants. This paper would focus on the four aspects of oropharyngeal colostrumadministration, that was theoretical basis,safety, feasibility,operating standards and the effect.

    At near-term age the brain undergoes rapid growth and development. Abnormalities identified during this period have been recognized as potential predictors of neurodevelopment in children born preterm. This study used diffusion tensor imaging (DTI) to examine white matter (WM) microstructure in very-low-birth-weight (VLBW) preterm infants to better understand regional WM developmental trajectories at near-term age. DTI scans were analyzed in a cross-sectional sample of 45 VLBW preterm infants (BW≤1500g, GA≤32weeks) within a cohort of 102 neonates admitted to the NICU and recruited to participate prior to standard-of-care MRI, from 2010 to 2011, 66/102 also had DTI. For inclusion in this analysis, 45 infants had DTI, no evidence of brain abnormality on MRI, and were scanned at PMA ≤40weeks (34.7-38.6). White matter microstructure was analyzed in 19 subcortical regions defined by DiffeoMap neonatal brain atlas, using threshold values of trace 0.15. Regional fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) were calculated and temporal-spatial trajectories of development were examined in relation to PMA and brain region location. Posterior regions within the corona radiata (CR), corpus callosum (CC), and internal capsule (IC) demonstrated significantly higher mean FA values compared to anterior regions. Posterior regions of the CR and IC demonstrated significantly lower RD values compared to anterior regions. Centrally located projection fibers demonstrated higher mean FA and lower RD values than peripheral regions including the posterior limb of the internal capsule (PLIC), cerebral peduncle, retrolenticular part of the IC, posterior thalamic radiation, and sagittal stratum. Centrally located association fibers of the external capsule had higher FA and lower RD than the more peripherally-located superior longitudinal fasciculus (SLF). A significant relationship between PMA-at-scan and FA, MD, and RD was

    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.

    1984-12-01

    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 Abstract Background Weight loss of greater than 7% from birth weight indicates possible feeding problems. Inadequate oral intake causes weight loss and increases the bilirubin enterohepatic circulation. The objective of this study was to describe the association between total serum bilirubin (TSB levels and weight loss in healthy term infants readmitted for hyperbilirubinemia after birth hospitalization. Methods We reviewed medical records of breastfed term infants who received phototherapy according to TSB levels readmitted to Caja Petrolera de Salud Clinic in La Paz, Bolivia during January 2005 through October 2008. Results Seventy-nine infants were studied (64.6% were males. The hyperbilirubinemia readmission rate was 5% among breastfed infants. Term infants were readmitted at a median age of 4 days. Mean TSB level was 18.6 ± 3 mg/dL. Thirty (38% had significant weight loss. A weak correlation between TSB levels and percent of weight loss was identified (r = 0.20; p 20 mg/dL was notably higher among infants with significant weight loss (46.7% vs. 18.4%; p Conclusions Significant weight loss could be a useful parameter to identify breastfed term infants at risk of severe hyperbilirubinemia either during birth hospitalization or outpatient follow-up visits in settings where routine pre-discharge TSB levels have not been implemented yet.

Todavia, há pouca literatura sobre minerais, especialmente sobre micronutrientes na nutrição do pré-termo extremo, considerando-se o deficiente armazenamento e a importância destes em nutrição. O principal enfoque desta revisão foi sobre o cálcio e o fósforo na mineralização óssea e na suplementação em nutrição parenteral e enteral, bem como a avaliação crítica da nutrição pós-alta sobre a mineralização óssea. São abordadas as necessidades de micronutrientes, principalmente selênio e zinco, e a função antioxidante do selênio na provável prevenção de doenças do prematuro com atuação de radicais livres. CONCLUSÃO: Considerando os baixos estoques de minerais em prematuros extremos, há necessidade de mais pesquisas sobre minerais na nutrição destes prematuros para definir suas reais necessidades, os aspectos metabólicos, bem como aplicar os conhecimentos na formulação de dietas que permitam prevenir quadros de deficiência e conseqüências a longo prazo. Ainda há controvérsias sobre a influência de fórmulas pós-alta sobre a evolução da doença óssea da prematuridade.OBJECTIVE: To review the literature on the role of calcium, phosphorus and trace elements in the nutrition of extremely low birth weight infants, considering their importance for metabolism, bone mineralization

    Objective To explore the relationship between infant feeding practices and infants growth,especially the weight gain for length in the first 6 months of life. Methods Two-hundred healthy full-term singlet normal birth weight 5 - 6 months old infants and their main care givers were recruited in Kongjiang community health service center in Shanghai. The questionnaires included infants feeding pattern, feeding environment and care givers feeding behaviors, and were completed on-site by investigators. The birth weight was obtained. The weight and length of infants at 6 months were measured. Results There were 70/200 (35.0%) infants overweight (BMI for age Z score>+1) at 6 months. There were more overweight boys than girls (40.0% vs. 30.9%, x2 = 1.798, P = 0.180). Compared with normal weight infants, the overweight infants had same birth weight (3.30 ± 0.35 kg vs. 3.35 ± 0.32 kg, t =1.010, P = 0.314) and same length at 6 months (67.64 ± 2.10 cm vs. 67.91 ± 1.97 cm, t=- 0.896, P = 0.371). However, the overweight infants gained much more weight for length in the first six months of life. At 6 months, the weight and BMI of overweight infants was significantly higher than that of normal weight infants (9.16 ± 0.67 vs. 7.94 ±0.64, t = 12.324, P 0.05). The grandparents played an important role in infants feeding in Shanghai. There were 39.0% infants fed only by grandparents, and 23.0% infants fed jointly by grandparents and parents (x2 = 0.175, P > 0.05).The care givers' educational level and knowledge of feeding skill were similar in overweight and normal weight infants (x2 = 0.446, t = 0.949, P > 0.05). However, the overweight infants were fed more quickly than normal weight infants (Z = 2.753, P +1),占35%.男婴超重多于女婴(40.0%对30.9%,x2=1.798,P=0.180).超重婴儿和体质量正常婴儿的出生体质量一致(3.30±0.35 kg对3.35±0.32 kg,t=1.010,P=0.314),6月龄时两组婴儿的身长也一致(67.64±2.10 cm对67.91±1.97cm,t=0.896,P=0.371).

    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.

Given the controversies surrounding use of probiotics in neonatal intensive care units, we address one additional aspect of routine implementation of probiotics for NEC prophylaxis – the pharmacoeconomic impact. Methods: Using data from our initial published experience, and continuing data collection after instituting a higher dose of L. reuteri, we measured the reduction in NEC in neonates with birth weight below 1000 g. Cost savings from prior studies examining the cost and outcomes of medical and surgical NEC were used to calculate the financial impact of routine L. reuteri DSM 17938 prophylaxis. Results: Medical records for 354 neonates were reviewed, 232 in the years before introduction of L. reuteri prophylaxis and 79 who received L. reuteri prophylaxis dosed at 0.1 mL daily and 43 neonates given a total daily dose of 0.2 mL as one or two doses. The incidence of NEC was significantly lower in the neonates who received L. reuteri (two of 122 neonates [1.6%] versus 35 of 232 neonates [15.1%]. The expected benefits for our neonatal intensive care unit per 100 extremely low-birth-weight neonates treated were four fewer deaths, five fewer cases of medical NEC, eight fewer cases of surgical NEC, one less patient with short-bowel syndrome, and a cost saving of approximately $2.2 million. Conclusion: Prophylactic

    Background: A previous randomized trial demonstrated an association between coffee intake and birth weight in smokers only. This could be a chance finding or because smoking interferes with caffeine metabolism. This study assessed the association between coffee intake during pregnancy and birth...... weight and whether it was modified by the mothers' smoking habits. Methods: In the Danish National Birth Cohort, coffee intake and smoking during pregnancy were recorded prospectively in 89,539 pregnancies that ended with live born singletons. Information on birth weight was obtained from the Danish...... Medical Birth Register. For a total of 71,000 pregnancies, complete information was available on coffee intake and all covariates for the second trimester. Results: Second-trimester coffee intake was associated with reduced birth weight in a dose–response pattern for non-smokers and smokers (9 g...

    The purpose of this study was to determine the relative importance of inadequate gestational weight gain as a cause of infant mortality. Birth and infant death certificate data were obtained from a random sample of 100,000 records from the National Center for Health Statistics (NCHS) 2002 Birth Cohort Linked Birth/Infant Death Data File. Descriptive and proportional hazards regression analyses were used to assess the odds of infant mortality associated with inadequate gestational weight gain compared to normal weight gain. Nearly 30% of women experienced inadequate weight gain. Infants born to women with inadequate gestational weight gain had odds of infant death that were 2.23 times the odds for infants born to women with normal weight gain. Increased odds remained after adjustment for gestational age, low birth weight, maternal age, maternal education, and maternal race. Among racial or ethnic subgroups, African American women were 1.3 times as likely as white women to have an infant die, but they were no more likely to have an infant die than white women if they had inadequate weight gain. There is a substantial and significant association between inadequate gestational weight gain and infant death that does not differ by race, ethnic group membership, or maternal age.

    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.

    Aim To investigate growth patterns and anthropometrics in former extremely low birth weight (ELBW, 0.67 SDS. At 11 years, anthropometrics, neurocognitive performance, body composition, grip strength and puberty scores were assessed. Results ELBW neonates displayed extra–uterine growth restriction with mean Z–scores for height, weight and head circumference of –0.77, –0.93 and –0.46 at birth, –1.61, –1.67 and –0.72 at 9 months, –1.22, –1.61 and –0.84 at 24 months, and –0.42, –0.49 and –1.09 at 11 years. ELBW children performed consistently worse on neurocognitive testing with an average intelligence quotient equivalent at 11 years of 92.5 (SD 13.1). Catch–up growth was not associated with neurocognitive performance. Compared to controls, ELBW cases had lower grip strength (13.6 vs. 15.9 kg) and percentage lean body weight (75.1 vs. 80.5%), but higher body fat (24.6 vs. 19.2%) and advanced puberty scores at 11 years (all P≤0.025). Catch–up growth for weight and height in the first two years of life in cases was associated with a lower percentage body fat compared to cases without catch–up growth (16.8% catch-up growth for weight vs. 25.7%, P<0.001; 20.9% catch-up for height vs. 25.8%, P = 0.049). Conclusions In young adolescence, former ELBW children still have difficulties to reach their target height. Compared to normal birth weight controls, ELBW adolescents show lower neurocognitive performance and grip strength and a higher percentage body fat, a potential risk factor for adverse health outcomes in adulthood. Our key finding is that catch–up growth in ELBW children in the first two years of life is associated with a lower percentage body fat and is therefore likely to be beneficial. PMID:28278233

    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.

    With advances in medical sciences, an increase in survival rates of low birth weight; increased incidence in use of catheter and antibiotics, and total parenteral nutrition are reported, therefore, the rate of fungal infections in late and very late onset neonatal sepsis have increased. Although fungal endocarditis rarely occur in newborns, it has a high morbidity and mortality. Antifungal therapy is often insufficient in cases who develop fungal endocarditis and surgical treatment is not preferred due to its difficulty and high mortality. Herein, fungal endocarditis in a preterm newborn treated with single-dose recombinant tissue plasminogen activator in addition to antifungal therapy is presented and relevant literature has been reviewed. The vegetation completely disappeared following treatment and no complication was observed.

    This study aimed to systematically review and appraise evidence on the short-term (e.g. morbidity, mortality) and long-term (obesity and non-communicable diseases, NCDs) health consequences of catch-up growth (vs. no catch-up growth) in individuals with a history of low birth weight (LBW).We searched MEDLINE, EMBASE, Global Health, CINAHL plus, Cochrane Library, ProQuest Dissertations and Thesis and reference lists. Study quality was assessed using the risk of bias assessment tool from the Agency for Health Care Research and Quality, and the evidence base was assessed using the GRADE tool. Eight studies in seven cohorts (two from high-income countries, five from low-middle-income countries) met the inclusion criteria for short-term (mean age: 13.4 months) and/or longer-term (mean age: 11.1 years) health outcomes of catch-up growth, which had occurred by 24 or 59 months. Of five studies on short-term health outcomes, three found positive associations between weight catch-up growth and body mass and/or glucose metabolism; one suggested reduced risk of hospitalisation and mortality with catch-up growth. Three studies on longer-term health outcomes found catch-up growth were associated with higher body mass, BMI or cholesterol. GRADE assessment suggested that evidence quantity and quality were low. Catch-up growth following LBW may have benefits for the individual with LBW in the short term, and may have adverse population health impacts in the long-term, but the evidence is limited. Future cohort studies could address the question of the consequences of catch-up growth following LBW more convincingly, with a view to informing future prevention of obesity and NCDs. © 2016 John Wiley & Sons Ltd.

    weight infants, keeping health professionals updated about this growing problem observed in neonatal units. SOURCES OF DATA: Original and review articles published over the past 15 years were searched in MEDLINE and Lilacs, using the following keywords: preterm infant, very low birth weight infants, sepsis, fungal infection, antifungal, Candida, amphotericin and fluconazole. SUMMARY OF THE FINDINGS: Invasive fungal infections affect especially preterm infants. Although new drugs (echinocandins to treat fungal infection are available, amphotericin is the most widely used drug for the treatment of systemic candidiasis at this stage of life. Currently, there are four types of antifungal agents used in the treatment of fungal infections in neonates: polyene macrolides (amphotericin B deoxycholate and lipid preparations, azoles (triazoles, fluorinated pyrimidines (flucytosine and echinocandins (caspofungin and micafungin. Two drugs capable of preventing invasive fungal infection are described: nystatin and fluconazole. The pharmacokinetics of fluconazole in the neonatal period is widely known and its prophylactic administration during the first six weeks of life has been associated with less invasive fungal infection in infants weighing less than 1,000 g at birth. CONCLUSIONS: Fungal infections constitute an important problem in the neonatal intensive care unit and a better understanding of the incidence, diagnosis, clinical management, treatment, and prophylaxis is important in order to reduce morbidity and mortality. The identification of high-risk preterm infants and the implementation of prophylactic measures and early treatment may improve the outcome of these patients.

    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.

    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.

    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.

    Full Text Available OBJETIVO: Determinar as idades cronológica e corrigida de aquisição das habilidades motoras até a marcha independente em prematuros de muito baixo peso e avaliar até quando é necessário o uso da idade corrigida. MÉTODOS: Estudo longitudinal de prematuros OBJECTIVE: To determine chronological and corrected ages at acquisition of motor abilities up to unaided walking in very low weight preterms and to determine up to what point it is necessary to use corrected age. METHODS: This was a longitudinal study of preterms with birth weight < 1,500 g and gestational age < 34 weeks, free from neurosensory sequelae, selected at the high-risk infants follow-up clinic at the Hospital das Clínicas, Faculdade de Medicina de Botucatu, Universidade Estadual Paulista (UNESP in Botucatu, Brazil, between 1998 to 2003, and assessed every 2 months until acquisition of unaided walking. RESULTS: Nine percent of the 155 preterms recruited were excluded from the study, leaving a total of 143 patients. The mean gestational age was 30±2 weeks, birth weight was 1,130±222 g, 59% were female and 44% were small for gestational age. Preterms achieved head control in their second month, could sit unaided at 7 months and walked at 12.8 months' corrected age, corresponding to the 4th, 9th and 15th months of chronological age. There were significant differences between chronological age and corrected age for all motor abilities. Preterms who were small for their gestational age acquired motor abilities later, but still within expected limits. CONCLUSIONS: Very low weight preterms, free from neurosensory disorders, acquired their motor abilities within the ranges expected for their corrected ages. Corrected age should be used until unaided walking is achieved.

    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. So the doctors for children′s care from basic hospitals should vigorously promote the method.%目的:探讨早期干预对极低出生体重早产儿体格及智能发育的影响。方法:选择本院2011年11月至2012年10月新生儿重症监护病房救治存活的极低出生体重早产儿32例做为干预组,选择2011年11月以前出生的9~15个月极低出生体重早产儿连续收录32例做为对照组,对干

    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.

    Full Text Available To describe temporal changes in systolic, diastolic, and mean blood pressure (SBP, DBP, and MBP, respectively in term and preterm infants immediately after birth.Prospective observational two-center study. In term infants SBP, DBP, and MBP were assessed non-invasively every minute for the first 15 minutes, and in preterm infants every minute for the first 15 minutes, as well as at 20, 25, 30, 45, and 60 minutes after birth. Regression analyses were performed by gender and respiratory support in all neonates; and by mode of delivery, cord clamping time, and development of ultrasound-detected brain injury in preterm neonates.Term infants (n = 54 had a mean (SD birth weight of 3298 (442 g and gestational age of 38 (1 weeks, and preterm infants (n = 94 weighed 1340 (672 g and were 30 (3 weeks gestation. Term infants' SBP, DBP and MBP within the first 15 minutes after birth were independent of gender or respiratory support. Linear mixed regression analysis showed that preterm infants, who were female, born vaginally, had delayed cord clamping and did not require positive pressure ventilation nor develop periventricular injury or ventriculomegaly, had significantly higher SBP, DBP, and MBP at some measurement points within the first hour after birth.We present novel reference ranges of BP immediately after birth in a cohort of term and preterm neonates. They may aid in optimization of cardiovascular support during early transition at all gestations.

    Full Text Available Background: reducing low birth weight is a priority in Cuba’s health policy since it is critical to reduce infant mortality. Objective: to identify the major risk factors associated with low birth weight in Cienfuegos municipality. Methods: a cross-sectional study involving all women who gave birth to low-birth-weight infants was conducted in Cienfuegos municipality from January 2010 through December 2014. Maternal age, maternal medical history, weight gain during pregnancy, nutritional assessment in early pregnancy, interpregnancy interval, gestational age at birth and pregnancy-related conditions were analyzed. Results: Four hundred fifty low-birth-weight infants were born. Hypertension as major illness in the maternal medical history was the main cause of maternal morbidity. In the obstetric history, an interpregnancy interval less than 2 years was frequently observed. It was demonstrated that the conditions mostly associated with pregnancy were vaginal infection, anemia and hypertension. Preterm infants predominated. Conclusions: the modification of these risk factors would have a favorable impact on the reduction of low birth weight.

    Low birth weight babies are defined as those weighing under 2,500 g. They make 13.5% of all births at the Maternity Hospital, Kuala Lumpur but contribute to 74.8% of all deaths. They are most likely to be Indian babies and least likely to be Chinese. Among all 3 communities, the primigravidae tend to produce smaller babies than multiparae but this is also true for the Indian of parity more than 3. The Malay teenager is more likely to produce small babies than their older counterparts but not so with the Indian and Chinese. There are definite clinical factors associated with or causing the births of small babies and the lighter the baby, the more influential are these factors. Maternal hypertension, antepartum haemorrhage, multiple pregnancy and unexplained intrauterine death are the 4 outstanding associations with both low birth weight and perinatal death. Although the spontaneous (often premature) onset of labour was the commonest preceding factor, it was much less important in the lowest birth weight groups of babies and was a less important contributor to perinatal death.

    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.

    The effects of administration of bifidobacteria on the intestinal microbiota in low-birth-weight infants, and the transition of each strain of administered bifidobacteria were investigated. A single strain of Bifidobacterium breve M-16V (5 × 10(8); one-species group) or a mixture of three species composed of B. breve M-16V, Bifidobacterium longum subsp. infantis M-63 and B. longum subsp. longum BB536 (5 × 10(8) of each strain; three-species group) were administered daily for 6 weeks. Bifidobacterial administration significantly increased the detection rates and cell numbers of bifidobacteria in the feces (weeks 1-6). The proportion of bifidobacteria was significantly higher in the one-species group at weeks 1-4, and in the three-species group at weeks 1-6 compared with the control group. Furthermore, the proportion of bifidobacteria in the three-species group was significantly higher than that in the one-species group at weeks 1 and 6. The proportion of infants with bifidobacteria-predominant microbiota was significantly higher in the three-species group than in the control group during the test period. The detection rates of Clostridium were lower in the bifidobacteria-administered groups. The proportions of Enterobacteriaceae were significantly lower in the three-species group compared to the other groups (weeks 4 and 6). Among the three strains administered, B. breve M-16V and Bifidobacterium infantis M-63 were detected in 85% or more of the infants during the administration period, while B. longum BB536 was detected in 40% or less. Compared with administration of one species, administration of three species of bifidobacteria resulted in earlier formation of a bifidobacteria-predominant fecal microbiota and maintenance of this microbiota.

    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.

    Background Perinatal mortality according to birth weight has an inverse J-pattern. Our aim was to estimate the influence of familial factors on this pattern, applying a cohort sibling design. We focused on excess mortality among macrosomic infants (>2 SD above the mean) and hypothesized that the birth weight-mortality association could be explained by confounding shared family factors. We also estimated how the participant’s deviation from mean sibling birth weight influenced the association. Methods and findings We included 1 925 929 singletons, born term or post-term to mothers with more than one delivery 1967–2011 registered in the Medical Birth Registry of Norway. We examined z-score birth weight and perinatal mortality in random-effects and sibling fixed-effects logistic regression models including measured confounders (e.g. maternal diabetes) as well as unmeasured shared family confounders (through fixed effects models). Birth weight-specific mortality showed an inverse J-pattern, being lowest (2.0 per 1000) at reference weight (z-score +1 to +2) and increasing for higher weights. Mortality in the highest weight category was 15-fold higher than reference. This pattern changed little in multivariable models. Deviance from mean sibling birth weight modified the mortality pattern across the birth weight spectrum: small and medium-sized infants had increased mortality when being smaller than their siblings, and large-sized infants had an increased risk when outweighing their siblings. Maternal diabetes and birth weight acted in a synergistic fashion with mortality among macrosomic infants in diabetic pregnancies in excess of what would be expected for additive effects. Conclusions The inverse J-pattern between birth weight and mortality is not explained by measured confounders or unmeasured shared family factors. Infants are at particularly high mortality risk when their birth weight deviates substantially from their siblings. Sensitivity analysis suggests

The complications of VLBW infants, blood transfusion, frequency of using pulmonary surfactant (PS), the duration of mechanical ventilation, the duration of oxygen and mortality were compared between two groups.Results The incidence of severe asphyxia, IVH and anemia was signiifcantly lower in experimental group than in control group (P< 0.05). The blood transfusion and transfusion volume, duration of mechanical ventilation, and duration of oxy-gen were signiifcantly lower in experimental group than in control group (P< 0.05).Conclusions Umbilical cord milking can reduce the incidence of severe asphyxia, IVH and anemia. It also can reduce the blood transfusion, the duration of mechanical ventilation, and the duration of oxygen in VLBW infants.

    [Objective] To investigate the relationship between perinatal risk factors and early neonatal death among very low birth weight (VLBW) infants. [Methods] A retrospective cohort of 143 VLBW infants admitted to NICU was studied. The dependent variable was the outcome, either survival or death at 7 days of life. The independent variables were assigned into three levels: distal, intermediate and proximal according to hierarchical model. All variables were subjected to univariate analysis and multivariate logistic regression. [Results] Early neonatal mortality was 13. 29% (19/143) in VLBW infants. After the adjustment of variables through multivariate Logistic regression it showed that infants born to mother with cord prolapse had higher risk exposure for early death than those of mother without cord prolapse in the distal level (AOR:8. 69;95%C/:1. 128~67. 002). At the intermediate level,infants with gestational age (GAX28 weeks and 5-min Apgar scores<7 had higher odds of early death than those of GA≥28 weeks and 5-min Apgar scores≥7 (AOR: 11. 47, 13. 55;95%CJ:2. 066~63. 712,3. 156 - 58. 221 respectively). At the proximal level, infants with intracranial hemorrhage (ICH) had higher risk of early death than those without ICH (AORS4. 56,95%C7:1. 088 - 19. 170). [Conclusions] The early neonatal mortality among VLBW infants is still high and continues to be a significant public health problem. Asphyxia at birth is the highest risk factor of early neonatal death. Reducing birth asphyxia through enhancing obstetric quality and strengthening cooperation between obstetric and neonatology department is still the key to decrease early neonatal death of VLBW infants.%[目的]探讨极低出生体重(very low birth weight,VLBW)儿早期死亡的围生期高危因素.

    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

    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.

    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.

    Pulmonary arterial hypertension (PAH) affects approximately 0.5% of human immunodeficiency virus (HIV)-infected adults with poor prognosis. The effectiveness of highly active antiretroviral therapy for treatment of HIV-related PAH (HIV-PAH) remains controversial. Little is known about the incidence, clinical course, and therapy options for PAH in HIV-1-infected pediatric patients. Here, we report the case of a preterm infant with HIV-related life-threatening PAH, which resolved after initiation of highly active antiretroviral therapy.

    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.

    Objective To examine associations in a preterm population between rs9883204 in ADCY5 and rs900400 near LEKR1 and CCNL1 with birth weight. Both markers were associated with birth weight in a term population in a recent genome-wide association (GWA) study by Freathy et al. Study design A meta-analysis of mother and infant samples was performed for associations of rs900400 and rs9883204 with birth weight in 393 families from the U.S., 265 families from Argentina and 735 mother-infant pairs from Denmark. Z scores adjusted for infant sex and gestational age were generated for each population separately and regressed on allele counts. Association evidence was combined across sites by inverse-variance weighted meta-analysis. Results Each additional C allele of rs900400 (LEKR1/CCNL1) in infants was marginally associated with a 0.069 standard deviation (SD) lower birth weight (95% CI = −0.159 – 0.022, P = 0.068). This result was slightly more pronounced after adjusting for smoking (P = 0.036). There were no significant associations identified with rs9883204 or in maternal samples. Conclusions These results indicate the potential importance of this marker on birth weight irrespective of gestational age. PMID:21885063

    Objective To investigate the treatment of symptomatic patent ductus arteriosus (PDA) in very low birth weight preterm infants. Methods From January 1, 2008 to December 31, 2010, 78 very low birth weight preterm infants (birth weight<1500 g) were diagnosed as symptomatic PDA. Among which, 42 cases administered orally with indomethacin (0.2 mg/kg, every 12 hrs for three times) were taken as treatment group, while five cases in this group who failed to indomethacin treatment were interrupted with video-assisted thoracoscopic surgery. And 36 cases who did not receive treatment for ductus arteriosus were taken as control group. The clinical outcomes, complications and prognosis of these patients were observed. Results There were no significant differences between the gentle percentage, gestational age, diameter of ductus arteriosus, rate of complicated with heart failure, sepsis, neonatal respiratory distress syndrome and intraventricular hemorrhage of two groups (P>0.05, respectively). The ductus arteriosus closed in 33 patients of treatment group (78.6%) and in nine patients of control group (25.0%)(χ2=22.39,P=0.000). There were no significant differences in serum creatinine level and platelet count between before and after the treatment in treatment group(P>0.05). Compared with control group, the treatment group had lower incidence of intraventricular hemorrhage (z=1.167, P=0.030), shorter duration of oxygen therapy [(8.0±5.5) d vs (13.3±9.3) d, t=2.225, P=0.032] and shorter hospital stay [(39.0±7.7) d vs (43.6±10.6) d, t=2.229, P=0.029]; while the incidence of bronchopulmonary dysplasia and necrotizing enterocolitis were similar (P>0.05). The five cases of PDA who received video-assisted thoracoscopic surgery were successfully interrupted with no residual shunt left, while three of them had lung infections and one had pleural effusion, but no pneumothorax and infant death associated with surgery occurred. Conclusions Symptomatic PDA of very low birth weight

    Full Text Available Objective: Due to recent scientific progress in assisted reproductive techniques (ART, infertile couples can now become fertile. Thus, a number of infants in our country are the results of these costly interventions. This study has been undertaken to evaluate the physical growth process of different methods of ART infants by standard growth charts from birth until nine months of age.Methods: This was a descriptive cross-sectional study of 333 infants conceived through ART [intracytoplasmic sperm injection (ICSI and in vitro fertilization (IVF] at Royan Institute. A sequential, non-random sampling method in a period of 22 months was used. Their growth was assessed by measuring infants weight, height and head circumference, and physical examination. The growth patterns were calculated by recording the values in standard growth charts. The final analysis was done with SPSS version 16 and by using Chi-square test.Findings: In comparison with growth charts, the weights of one-third of the infants were less than two standard deviations (SD at birth and one-fourth had head circumference less than three SD at birth. Low birth weight (LBW infants were six times more than infants of normal population. From birth to six months of age, growth abnormalities were seen in a substantial number of infants. However, at nine months of age, there was no significant difference observed between infants conceived by different methods of ART (IVF and ICSI.Conclusion: Multiple births are the most important confounding factor impacting the growth process of ART infants. Multiple pregnancies can lead to low birth weight, height and head circumference, and growth abnormalities up to six months of age. This abnormality improves by increasing age of the infants.

    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

    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.

    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.

  17. Medical, nutritional, and dental considerations in children with low birth weight.

    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.

    The objective of this study was to assess minor neurological dysfunction, cognitive development, and somatic development after dexamethasone therapy in very-low-birthweight infants. Thirty-three children after dexamethasone treatment were matched to 33 children without dexamethasone treatment. Data were assessed at the age of 3-7 years. Dexamethasone was started between the 7th and the 28th day of life over 7 days with a total dose of 2.35 mg/kg/day. Exclusion criteria were asphyxia, malformations, major surgical interventions, small for gestational age, intraventricular haemorrhage grades III and IV, periventricular leukomalacia, and severe psychomotor retardation. Each child was examined by a neuropediatrician for minor neurological dysfunctions and tested by a psychologist for cognitive development with a Kaufman Assessment Battery for Children and a Draw-a-Man Test. There were no differences in demographic data, growth, and socio-economic status between the two groups. Fine motor skills and gross motor function were significantly better in the control group (pdevelopment of speech, social development, and the Kaufman Assessment Battery for Children. After dexamethasone treatment, children showed a higher rate of minor neurological dysfunctions. Neurological development was affected even without neurological diagnosis. Further long-term follow-up studies will be necessary to fully evaluate the impact of dexamethasone on neurological and cognitive development.

    Extrauterine growth restriction is a major clinical problem for very low and extremely low birth weight infants.They need the rapid accumulation of protein and energy after born;otherwise it will lead to an increase in nutritional deficiencies,malnutrition and neurological problems.The ideal nutritional strategies is to provide parenteral nutrition after birth,amino acids and lipids are initially provided at a minimum of 2.0 g/(kg · d) and 1.0 g/(kg — d),which advance to 3.5-4.0 g/(kg · d) and 3.0 g/(kg · d),keep the appropriate protein/energy ratio.The appropriate vitamin,minerals and elements should be provided.Enteral feeding should be initiated immediately about 24 h after birth,minimal feeding [10-20 mL/(kg · d)] should last 3-5 days.Human milk should gradually increase to 75-120 mL/(kg · d) and add human milk fortifier.Parenteral nutrition is stopped when human milk fed to 120 mL/(kg · d).%极低和超低出生体质量儿出生早期如无快速积累蛋白和能量,将发生营养不足,导致神经发育不良和疾病的增加.理想的营养策略为出生就开始肠外营养,氨基酸、脂肪乳剂分别从2.0 g/(kg·d)和1.0g/(kg·d)开始,并快速达到3.5 ~4.0g/(kg·d)、3.0 g/(kg·d),保持适当的蛋白/能量比,合理添加维生素、矿物质和微量元素.肠内营养于出生后24 h左右开始喂养,微量喂养10~20 mL/(kg·d),持续3~5d后逐渐增加奶量.母乳喂养者奶量增至75~ 120 mL/(kg·d)可添加母乳强化剂.奶量至120 mL/(kg·d)停肠外营养.

    Full Text Available Abstract Background Studies have identified relationships between air pollution and birth weight, but have been inconsistent in identifying individual pollutants inversely associated with birth weight or elucidating susceptibility of the fetus by trimester of exposure. We examined effects of prenatal ambient pollution exposure on average birth weight and risk of low birth weight in full-term births. Methods We estimated average ambient air pollutant concentrations throughout pregnancy in the neighborhoods of women who delivered term singleton live births between 1996 and 2006 in California. We adjusted effect estimates of air pollutants on birth weight for infant characteristics, maternal characteristics, neighborhood socioeconomic factors, and year and season of birth. Results 3,545,177 singleton births had monitoring for at least one air pollutant within a 10 km radius of the tract or ZIP Code of the mother's residence. In multivariate models, pollutants were associated with decreased birth weight; -5.4 grams (95% confidence interval -6.8 g, -4.1 g per ppm carbon monoxide, -9.0 g (-9.6 g, -8.4 g per pphm nitrogen dioxide, -5.7 g (-6.6 g, -4.9 g per pphm ozone, -7.7 g (-7.9 g, -6.6 g per 10 μg/m3 particulate matter under 10 μm, -12.8 g (-14.3 g, -11.3 g per 10 μg/m3 particulate matter under 2.5 μm, and -9.3 g (-10.7 g, -7.9 g per 10 μg/m3 of coarse particulate matter. With the exception of carbon monoxide, estimates were largely unchanged after controlling for co-pollutants. Effect estimates for the third trimester largely reflect the results seen from full pregnancy exposure estimates; greater variation in results is seen in effect estimates specific to the first and second trimesters. Conclusions This study indicates that maternal exposure to ambient air pollution results in modestly lower infant birth weight. A small decline in birth weight is unlikely to have clinical relevance for individual infants, and there is debate about whether

    Infant mortality, stillbirths, and preterm births are major public health priorities with significant disparities based on race and ethnicity. Interestingly, when evaluating the rates over the past 30 to 50 years, the disparity persists in all three and is remarkably consistent. In the United States, the infant mortality rate is 6.7 deaths per 1,000 live births, the stillbirth rate is 6.2 per 1,000 deliveries, and the preterm birth rate is 12.8% of live births. The rates among non-Hispanic African Americans are dramatically higher, nearly double the infant mortality at 13.4 infant deaths per 1,000 live births, nearly double the stillbirth rate at 11.1 stillbirths per 1,000 deliveries, and one third higher with preterm births at 18.4% of live births. Despite numerous conferences, workshops, articles, and investigators focusing on this line of work, the disparities persist and, in some cases, are growing. In this article, we summarize a Eunice Kennedy Shriver National Institute of Child Health and Human Development workshop that focused on these disparities to identify the associated factors to determine their relative contributions, identify gaps in knowledge, and develop specific strategies to address the disparities in the short-term and long-term.

    Disseminated Candida infection in the very and extremely low birth weight infants is one of the most pathogens for the late onset of sepsis. Central nervous system Candida infection, such as microabscess, does not show specific manifestations in spite of multiple pathological involvements which often could not be demonstrated by microbiological and cellular examinations of cerebral spinal fluid. The examination of cerebral spinal fluid combined with brain imaging should be taken into consideration on the diagnosis of central nervous system Candida infection, particularly diffusion-weighted MRI could play more important role in early diagnosis of cerebral microabscess.%全身播散性假丝酵母菌感染已成为极低和超低出生体质量儿晚发感染的主要病原之一,而其导致的中枢神经系统受累的临床表现缺乏特异性、神经病理学的多样性使得脑脊液微生物学和常规细胞学分析不能除外特殊的损伤类型,特别是微小脑脓肿.因此中枢神经系统假丝酵母菌感染的诊断必须结合脑脊液和影像学检查,磁共振弥散加权成像可能成为早期诊断微小脓肿的重要方法.

    Full Text Available OBJETIVO: Verificar se a freqüência respiratória (FR, o volume corrente (VC e a relação FR/VC poderiam prever a falha na extubação em recém-nascidos de muito baixo peso submetidos à ventilação mecânica. MÉTODOS: Estudo prospectivo, observacional, de recém-nascidos com idade gestacional OBJECTIVE: To verify if respiratory rate (RR, tidal volume (TV and respiratory rate and tidal volume ratio (RR/TV could predict extubation failure in very low birth weight infants submitted to mechanical ventilation. METHODS: This prospective observational study enrolled newborn infants with gestational age <37 weeks and birth weight <1,500g, mechanically ventilated from birth during 48 hours to 30 days and thought to be ready for extubation. As soon as the physicians decided for extubation, the neonates received endotracheal continuous positive airway pressure (CPAP for 10 minutes while spontaneous RR, TV and RR/TV were measured using a fixed-orifice pneumotachograph positioned between the endotracheal tube and the ventilator circuit. Thereafter, the neonates were extubated to nasal CPAP. Extubation failure was defined as the need for reintubation within 48 hours. RESULTS: Of the 35 studied infants, 20 (57% were successfully extubated and 15 (43% required reintubation. RR and RR/TV before extubation had a trend to be higher in unsuccessfully extubated infants. TV was similar in both groups. Sensitivity and specificity of these parameters as predictors of extubation failure were 50 and 67% respectively for RR, 40 and 67% for TV and 40 and 73% for RR/TV. CONCLUSIONS: RR, TV and RR/TV showed low sensitivity and specificity to predict extubation failure in mechanically ventilated very low birth weight infants.

    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.

    Because low birth weight is associated with adverse cardiovascular risk and death in adults, lipoprotein heterogeneity at birth was studied. A prominent, large high-density lipoprotein (HDL) subclass enriched in apolipoprotein C-I (apoC-I) was found in 19 percent of infants, who had significantly lower birth weights and younger gestational ages and distinctly different lipoprotein profiles than infants with undetectable, possible or probable amounts of apoC-I-enriched HDL. An elevated amount of an apoC-I-enriched HDL identifies a new group of low birth weight infants.

    Objective: It is important to identify the possible risk factors for the occurrence of large for gestational age (LGA) in newborns and to determine the effect of birth weight and metabolic parameters on subsequent growth. We aimed to determine the effects of maternal weight, weight gain during pregnancy, maternal hemoglobin A1c (HbA1c), C-peptide and insulin as well as cord C-peptide and insulin levels on birth weight and postnatal growth during the first two years of life. Methods: Healthy, non-diabetic mothers and term singleton newborns were included in this prospective case-control cohort study. Fasting maternal glucose, HbA1c, C-peptide and insulin levels were studied. Cord blood was analyzed for C-peptide and insulin. At birth, newborns were divided into two groups according to birth size: LGA and appropriate for GA (AGA). Infants were followed at six-month intervals for two years and their length and weight were recorded. Results: Forty LGA and 43 AGA infants were included in the study. Birth weight standard deviation score (SDS) was positively correlated with maternal body mass index (BMI) before delivery (r=0.2, p=0.04) and with weight gain during pregnancy (r=0.2, p=0.04). In multivariate analyses, the strongest association with macrosomia was a maternal C-peptide level >3.85 ng/mL (OR=20). Although the LGA group showed decreased growth by the 6-month of follow-up, the differences between the LGA and AGA groups in weight and length SDS persisted over the 2 years of follow-up. Conclusion: The control of maternal BMI and prevention of overt weight gain during pregnancy may prevent excessive birth weight. The effect of the in utero metabolic environment on the weight and length SDS of infants born LGA persists until at least two years of age. PMID:26831549

    Full Text Available Abstract Background The scientific literature poses a perplexing dilemma for pregnant women with respect to the consumption of fish from natural bodies of water. On one hand, fish is a good source of protein, low in fat and a rich source of other nutrients all of which have presumably beneficial effects on developing embryos and fetuses. On the other hand, consumption of fish contaminated with environmental toxicants such as polychlorinated biphenyls (PCBs has been associated with decrements in gestation and birth size. Methods 2,716 infants born between 1986–1991 to participants of the New York State Angler Cohort Study were studied with respect to duration of maternal consumption of contaminated fish from Lake Ontario and its tributaries and gestation and birth size. Hospital delivery records (maternal and newborn were obtained for 92% of infants for the ascertainment of gestation (weeks, birth size (weight, length, chest, and head circumference and other known determinants of fetal growth (i.e., maternal parity, history of placental infarction, uterine bleeding, pregnancy loss or cigarette smoking and infant's race, sex and presence of birth defect. Duration of maternal fish consumption prior to the index infant's birth was categorized as: none; 1–2, 3–7, 8+ years, while birth weight (in grams, birth length (in centimeters, and head and chest circumference (in centimeters were left as continuous variables in multiple linear regression models. Birth size percentiles, ponderal indices and head to chest circumference ratios were computed to further assess proportionality and birth size in relation to gestational age. Results Analysis of variance failed to identify significant mean differences in gestation or any measure of birth size in relation to duration of maternal lifetime fish consumption. Multiple linear regressions identified gestational age, male sex, number of daily cigarettes, parity and placental infarction, as significant

    2010-01-01

    Full Text Available Abstract Background Infection with Plasmodium falciparum during pregnancy contributes substantially to the disease burden in both mothers and offspring. Placental malaria may lead to intrauterine growth restriction or preterm delivery resulting in low birth weight (LBW, which, in general, is associated with increased infant morbidity and mortality. However, little is known about the possible direct impact of the specific disease processes occurring in PM on longer term outcomes such as subsequent retarded growth development independent of LBW. Methods In an existing West-African cohort, 783 healthy infants with a birth weight of at least 2,000 g were followed up during their first year of life. The aim of the study was to investigate if Plasmodium falciparum infection of the placenta, assessed by placental histology, has an impact on several anthropometric parameters, measured at birth and after three, six and 12 months using generalized estimating equations models adjusting for moderate low birth weight. Results Independent of LBW, first to third born infants who were exposed to either past, chronic or acute placental malaria during pregnancy had significantly lower weight-for-age (-0.43, 95% CI: -0.80;-0.07, weight-for-length (-0.47, 95% CI: -0.84; -0.10 and BMI-for-age z-scores (-0.57, 95% CI: -0.84; -0.10 compared to infants born to mothers who were not diagnosed with placental malaria (p = 0.019, 0.013, and 0.012, respectively. Interestingly, the longitudinal data on histology-based diagnosis of PM also document a sharp decline of PM prevalence in the Sukuta cohort from 16.5% in 2002 to 5.4% in 2004. Conclusions It was demonstrated that PM has a negative impact on the infant's subsequent weight development that is independent of LBW, suggesting that the longer term effects of PM have been underestimated, even in areas where malaria transmission is declining.

    Full Text Available Research question: What is the extent of low weight babies born in hospitals and its association with some maternal factors? Objectives: 1. 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.

    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.

    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

    Contact behaviours such as touch, have been shown to be influential channels of nonverbal communication between mothers and infants. While existing research has examined the communicative roles of maternal or infant touch in isolation, mutual touch, whereby touching behaviours occur simultaneously between mothers and their infants, has yet to be examined. The present study was designed to investigate mutual touch during face-to-face interactions between mothers and their 5½-month-old fullterm (n=40), very low birth weight/preterm (VLBW/preterm; n=40) infants, and infants at psychosocial risk (n=41). Objectives were to examine: (1) how the quantitative and qualitative aspects of touch employed by mothers and their infants varied across the normal periods of the still-face (SF) procedure, and (2) how these were associated with risk status. Mutual touch was systematically coded using the mother-infant touch scale. Interactions were found to largely consist of mutual touch and one-sided touch plus movement, highlighting that active touching is pervasive during mother-infant interactions. Consistent with the literature, while the SF period did not negatively affect the amount of mutual touch engaged in for mothers and their fullterm infants and mothers and their infants at psychosocial risk, it did for mothers and their VLBW/preterm infants. Together, results illuminate how both mothers and infants participate in shaping and co-regulating their interactions through the use of touch and underscore the contribution of examining the influence of birth status on mutual touch.

    Full Text Available Abstract Background Birth weight plays an important role in infant mortality and morbidity, childhood development, and adult health. To date there are contradictory results regarding the role of physical activity on birth weight. In addition, it is questioned whether exercise during second and third trimesters of pregnancy might affect gestational age and increase the risk of preterm delivery. Hence, the purpose of this study was to examine the effect of a supervised exercise-program on birth weight, gestational age at delivery and Apgar-score. Methods Sedentary, nulliparous pregnant women (N = 105, mean age 30.7 ± 4.0 years, pre-pregnancy BMI 23.8 ± 4.3 were randomized to either an exercise group (EG, n = 52 or a control group (CG, n = 53. The exercise program consisted of supervised aerobic dance and strength training for 60 minutes, twice per week for a minimum of 12 weeks, with an additional 30 minutes of self-imposed physical activity on the non-supervised week-days. Results There was no statistically significant difference between groups in mean birth weight, low birth weight ( Conclusion Aerobic-dance exercise was not associated with reduction in birth weight, preterm birth rate or neonatal well-being.

    Obesity is a risk factor for gestational diabetes, whereas the role of the mother's birth weight is more uncertain. We aimed to investigate the combined effect of mothers' birth-weight-for-gestational-age and early pregnancy Body Mass Index (BMI) in relation to risk of gestational diabetes. Between 1973 and 2006, we identified a cohort of 323,083 women included in the Swedish Medical Birth Register both as infants and as mothers. Main exposures were mothers' birth-weight-for-gestational-age (categorized into five groups according to deviation from national mean birth weight) and early pregnancy BMI (classified according to WHO). Rates of gestational diabetes increased with adult BMI, independently of birth-weight-for-gestational-age. However, compared to women with appropriate birth-weight-for-gestational-age [appropriate-for-gestational age (AGA); -1 to +1 SD] and BMI (born small-for-gestational-age [small for gestational age (SGA); born large-for-gestational-age [large-for-gestational-age (LGA); >2SD], and OR = 10.4 (95 % CI 8.4-13.0) if born AGA. Risk of gestational diabetes is not only increased among obese women, but also among women born SGA and LGA. Severely obese women born with a low or a high birth-weight-for-gestational-age seem more vulnerable to the development of gestational diabetes compared to normal weight women. Normal pre-pregnancy BMI diminishes the increased risk birth size may confer in terms of gestational diabetes. Therefore, the importance of keeping a healthy weight cannot be overemphasized.

    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.

    Objectives To investigate the delivery mode and perinatal outcomes of low birth weight infants in mainland China, and to explore the appropriate delivery mode and timing of delivery. Methods Clinical data of 103 678 babies delivered from Jan 1st to Dec 31th, 2011 in 39 hospitals in mainland China were analyzed retrospectively. The 39 hospitals located in 7 administrative regions, including Northeast, Northwest, North, Central, East, South and Southwest China. Result (1) The average birth weight of the newborns was (3 263 ± 540) g. Among them, 7 474 cases were diagnosed low birth weight infants, with the incidence of 7.209%(7 474/103 678). There were 2.328%(2 214/95 116 ) full-term low birth weight infants and 61.434% (5 260/8 562 ) preterm low birth weight infants. (2) From week 28 to week 36, the cesarean section rate of low birth weight infants increased with the increasing of gestational weeks. The cesarean section rate of full-term low birth weight infants were 61.14%(1 139/1 863) , which was higher than that of normal birth weight infants (52.947%, 45 108/85 195). The differences were statistically significant (P<0.01). (3) The constitution of the indication of cesarean section showed that social factor and maternal factor were 10.73%(443/4 128) and 48.91%(2 019/4 128) for low birth weight infants, respectively. While for the normal birth weight infants, they were 27.70%(12 495/45 108) and 38.60%(17 412/45 108), respectively. There was statistically significant difference(P<0.01). (4) The emergency cesarean section rate of full-term low birth weight infants was 41.09%(468/1 139), which was higher than that of normal birth weight infants (31.09%, 14 024/45 108). The difference was statistically significant (P<0.01). (5) The rates of stillbirth, neonatal asphyxia and the mortality of full-term low birth weight infants were 2.36%(44/1 863), 6.12%(114/1 863), and 3.17%(59/1 863), respectively.

    Introduction Periodontal disease is a neglected bacterial infection that causes destruction of the periodontium in pregnant women. Yet its impact on the occurrence of adverse pregnancy outcomes has not systematically evaluated and there is no clear statement on the relationship between periodontal disease and preterm low birth weight. The objective of this study was to summarize the evidence on the impact of periodontal disease on preterm low birth weight. Methods We searched the following data bases from January 2005 to December 2015: CINAHL (cumulative index to nursing and allied health literature), MEDLINE, AMED, EMBASE (excerpta medica database), Cochrane library and Google scholar. Only case-control studies with full text in English were eligible. Critical appraisal of the identified articles was done by two authors independently to provide the possible relevance of the papers for inclusion in the review process. The selected Case control studies were critically appraised with 12 items structured checklist adapted from national institute of health (NIH). Odds ratio (OR) or risk ratios (RR) were extracted from the selected studies. The two reviewers who selected the appropriate studies also extracted the data and evaluated the risk of bias. Results Of 229 articles, ten studies with a total of 2423 participants with a mean age ranged from 13 to 49 years were met the inclusion criteria. The studies focused on preterm birth, low birth weight and /or preterm low birth weight and periodontitis. Of the selected studies, 9 implied an association between periodontal disease and increased risk of preterm birth, low birth weight and /or preterm low birth weight outcome (ORs ranging from 2.04 to 4.19) and only one study found no evidence of association. Conclusion Periodontal disease may be one of the possible risk factor for preterm low birth weight infant. However, more precise studies with randomized clinical trial with sufficient follow-up period must be done to

    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.

    Objective To explore the application of umbilical venous catheter (UVC) combined with peripherally inserted central catheter (PICC) in divided period in very low birth weight infants (VLBWI). Methods One hundred and eleven VLBWIs from January 2010 to December 2011 were divided into combined catheter group (UVC and PICC) with 51 cases and PIV (peripheral vein) plus PICC group with 60 cases. Venous catheter situation, physical indications and catheter infection during hospitalization were monitored. Results The one-shot success rate in combined catheter group was higher than that of PIV plus PICC group, but lower incidence of infusion extravasation in combined catheter group. Correction time of hypoglycemia had no significant difference between the two groups, however but the frequency of apnoea and the time of weight up to 2 kg had (P<0.01). Conclusion With combined central venous catheterization, a higher success rate of intravenous puncture could be achieved with longer retention time, but lower incidence of infusion extravasation, which provides a safe and effective venous channel for VLBWI.%  目的探讨分时段脐静脉置管和经外周静脉置入中心静脉导管(peripherally inserted central catheter,PICC)置管在极低出生体质量儿中的应用效果。方法选取2010年1月—2011年12月入院的极低出生体质量儿111例,分为分时段应用脐静脉置管、PICC组(观察组)51例和外周静脉置管加PICC组(对照组)60例,监测两组住院期间的静脉置管情况、患儿身体指征反应及导管感染情况。结果观察组PICC 1次置管成功率高于对照组,输液外渗发生率低(P<0.01);两组患儿纠正低血糖所需时间差异无统计学意义;呼吸暂停次数、体质量增长至2 kg时间经比较差异有统计学意义(P<0.01)。结论采用分时段中心静脉置管具有穿刺成功率高,留置时间长,输液外渗发生率低,且不增加感染的优点,能最大限

    Objective To assess the effect of parenteral (PN) glutamine supplementation on gut function in the very low birth weight infants(VLBWIs). Methods A muhicentered, randomized, double-blinded, clinical trial was conducted. Thirty VLBWIs (<1500 g at birth) at two children's medical centers were randomly and equally assigned to either control group [sPN; amino acid was given at the dosage recommended by Chinese guidelines for the use of nutritional support in critically ill neonates(Jun. 2006)] or glutamine-supplemented group [GInPN; glutamine intake, 0. 3 g/(kg · d)]. The primary endpoints were the time to achieve full enteral nutrition, the incidence of gastric residuals, duration of parenteral nutrition and mortality. Results There were no significant differences between GInPN and sPN group in the time to achieve full enteral nutrition [(20±6)d vs (21±9)d], the number of gastric residuals [(3±4) vs (1±2)] and duration of parenteral nutrition [(17±7)d vs (17±8)d]. Of the 15 infants in the GlnPN group, 2 dropped out and 4 suspended treatment, and 4 in the control group suspended treatment (intention-to-treat analysis showed RR= 1.182; 95%CI:0. 937-1. 490). Conclusions Parenteral glutamine supplementation can not shorten the time to achieve full enteral nutrition and duration of parenteral nutrition, or reduce the incidence of gastric residuals and mortality in VLBWIs.%目的 评价含丙氨酰谷氨酰胺(Ala-Gln)肠外营养(parenteral-nutrition,PN)对极低出生体重儿肠道功能的影响.方法 对两家儿童医疗中心2006年4月至2007年2月收治的30例极低出生体重儿进行研究,采用平行、随机、双盲、对照试验,随机分为常规PN组(对照组)和常规PN+Ala-Gin组(研究组),两组各15例,对照组按照常规给予肠外营养支持,氨基酸的剂量按照中国新生儿营养支持临床应用指南给予[从1.0~2.0 g/(kg·d)开始,增至3.5 g/(kg·d)];研究组添加0.3 g/(kg·d)Ala-Gln双肽,其中Ala-Gln双肽取

  20. The relation of polychlorinated biphenyls to birth weight and gestational age in the offspring of occupationally exposed mothers

    The authors studied the relation of polychlorinated biphenyls (PCBs) to birth weight and gestational age among the live offspring of women occupationally exposed to PCBs during the manufacture of capacitors in Upstate New York. Interviews were conducted in 1982 with 200 women who had held jobs with direct exposure and 205 women who had never held a direct-exposure job in order to ascertain information on reproductive history and other factors influencing reproductive outcome. Exposure was assessed as high-homolog PCB (Aroclor 1254), a continuous exposure variable estimated from an independently derived prediction model. After adjustment for variables other than gestational age known to influence birth weight, a significant effect of high-homolog exposure is seen for birth weight. For gestational age, a small but significant decrease is also observed with an increase in estimated exposure. When gestational age is accounted for in addition to other variables related to birth weight, estimated serum PCB is no longer a significant predictor of birth weight. The authors conclude that these data indicate that there is a significant relation between increased estimated serum PCB level and decreased birth weight and gestational age, and that the decrease in birth weight is at least partially related to shortened gestational age. The magnitude of these effects was quite small compared with those of other known determinants of gestational age and birth weight, and the biologic importance of these effects is likely to be negligible except among already low birth weight or short gestation infants.

    Women with severe renal failure rarely conceive, and when they do become pregnant these women often deliver prematurely. The clinical course of mothers with renal failure has been described, but little attention has been given to the offspring. In this report, we provide data on three infants born prematurely to mothers either on dialysis or with severe renal failure. The infants were the appropriate size for gestational age and demonstrated no obvious physical abnormalities. Laboratory data, including renal function, was also within normal limits. Renal size in the two infants studied by ultrasound was near or above the 95th percentile when corrected for gestational age. The premature birth appeared to be a function of maternal complications rather than a primary in utero growth disturbance.

    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.

In women of reproductive age, chronic hookworm infections cause iron deficiency anaemia, which, upon pregnancy, can lead to intrauterine growth restriction and low birth weight. Low birth weight is an important risk factor for neonatal and infant mortality and morbidity. METHODOLOGY: We investigated the association between neonatal birth weight and a 4-monthly deworming and weekly iron-folic acid supplementation program given to women of reproductive age in north-west Vietnam. The program was made available to all women of reproductive age (estimated 51,623 in two districts in Yen Bai Province for 20 months prior to commencement of birth weight data collection. Data were obtained for births at the district hospitals of the two intervention districts as well as from two control districts where women did not have access to the intervention, but had similar maternal and child health indicators and socio-economic backgrounds. The primary outcome was low birth weight. PRINCIPAL FINDINGS: The birth weights of 463 infants born in district hospitals in the intervention (168 and control districts (295 were recorded. Twenty-six months after the program was started, the prevalence of low birth weight was 3% in intervention districts compared to 7.4% in control districts (adjusted odds ratio 0.29, 95% confidence interval 0.10 to 0.81, p = 0.017. The mean birth weight was 124 g (CI 68 - 255 g, p<0.001 greater in the intervention districts compared to control districts. CONCLUSIONS/SIGNIFICANCE: The findings of this study suggest that providing women with regular deworming and weekly iron-folic acid supplements before pregnancy is associated with a reduced prevalence of low birth weight in rural Vietnam. The impact of this health system-integrated intervention on birth outcomes should be further evaluated through a more extensive randomised-controlled trial.

    Objective We examine disparities in birth weight and gestational age by ethnic ancestry in 2000–2011 in eight South American countries. Methods The sample included 60480 singleton live-births. Regression models were estimated to evaluate differences in birth outcomes by ethnic ancestry controlling for time trends. Results Significant disparities were found in seven countries. In four countries – Brazil, Ecuador, Uruguay, and Venezuela – we found significant disparities in both low birth weight and preterm birth. Disparities in preterm birth alone were observed in Argentina, Bolivia, and Colombia. Several differences in continuous birth weight, gestational age, and fetal growth rate were also observed. There were no systematic patterns of disparities between the evaluated ethnic ancestry groups across the study countries, in that no racial/ethnic group consistently had the best or worst outcomes in all countries. Conclusions Racial/ethnic disparities in infant health are common in several South American countries. Differences across countries suggest that racial/ethnic disparities are driven by social and economic mechanisms. Researchers and policymakers should acknowledge these disparities and develop research and policy programs to effectively target them. PMID:25542227

    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.

    Introduction: Recent evidence suggests that preterm birth is a possible risk factor for high blood pressure (BP) in later life. The most widely quoted blood pressure centiles for very low birth weight (VLBW, ≤1500 g birth weight) infants at corrected term gestation is based on a cohort with mostly late preterm or term infants (Zubrow curves). Objectives: The objective of this study was to determine the clinical utility of the Zubrow curves in diagnosis of hypertension in VLBW infants at their term corrected gestational age (CGA). Patients and Methods: In a case-control study, we compared BP in 75 VLBW infants at 40 weeks CGA (cases) to 69 full term infants admitted to neonatal intensive care unit (NICU) (controls). Results: In spite of having lower weights, VLBW infants compared to term infants (2612.8 ± 546 vs. 3308.2 ± 373 g, P ≤ 0.001) had higher average systolic (88.8 ± 7.6 vs. 82.33 ± 8.5 mm Hg; P ≤ 0.001) and mean BP (61.2 ± 6.6 vs. 57.61 ± 6.9, P = 0.01). Although 41% (31/75) VLBW infants would have met the criteria for hypertension according to Zubrow curves only 4% (3/75) were diagnosed with hypertension. Conclusion: Since Zubrow BP centiles were based on a heterogeneous population of infants including preterm and term infants, new BP centiles based on chronological data from VLBW infants would allow a better definition of hypertension in these infants and identify the threshold BP for initiating treatment.

    investigated the association of birth weight with adult all-cause mortality using a Danish school-based cohort of 216,464 men and women born from 1936 through 1979. The cohort was linked to vital statistic registers. The main outcome was all-cause mortality from ages 25 through 68 years. Associations...... with death from cancer, circulatory disease, and all other causes were also examined. RESULTS: During 5,205,477 person-years of follow-up, 11,149 deaths occurred among men and 6609 among women. The cumulative hazard ratios of the association between birth weight categories and all-cause mortality...... was constant for all ages investigated and did not differ between men and women. Compared with subjects having birth weights in the reference category (3251-3750 g), those with the lowest birth weights (2000-2750 g) had 17% higher mortality (95% confidence interval = 1.11-1.22), and those with the highest...

    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.

    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.

    Objective To demonstrate the association between fluid intake and sodium intake during the first 10 days of life and the risk of chronic lung disease (CLD) in very low birth weight (VLBW) infants.Methods A retrospective analysis of data from VLBW infants enrolled in the Neonatal Department of our hospital; 130 infants with birth weight between 790 and 1 470 g were randomized, among which 12 infants was diagnosised CLD. The daily fluid intake and sodium intake during the first 10 days of life were compared between the infants without CLD and those who developed CLD. Demographic and clinical neonatal variables were also compared. Results 118 infants survived without CLD and 12 infants developed CLD. Analysis showed that the daily fluid intakes were higher (day 2~10) and weight loss less (day 6~9) in the group of infants who developed CLD. In addition, the daily sodium intakes were also higher (day 2~6) in infants who developed CLD. Conclusion In the VLBW infants treated during the post surfactant era, higher fluid or sodi-um intake during the first 10 days of life were associated with an increased risk of CLD. The finding suggests that careful attention to fluid balance might be an important means to reduce the incidence of CLD.%目的 评估极低出生体重儿(VLBW)生后前10 d液体和钠摄入量与发生慢性肺疾病(CLD)的风险性.方法 回顾性分析我院新生儿科住院的130例VLBW的资料,比较无CLD的存活早产儿和患有CLD的新生儿在生后前10 d每天液体和钠摄入量和体重下降的情况.同时比较临床表现方面的变量.结果 无CLD的存活新生儿118例,患有CLD的新生儿12例.单变量分析显示发生CLD的新生儿组每日液体摄入量更高(第2~10d),体重下降更少(第6~9d).CLD组钠的摄入量更高(第2~6 d).除此之外,出生体重较低、胎龄较小、男孩、较长时间的辅助通气等都与CLD的发生率较高相关.结论 VLBW新生儿生后前10 d较高的液体、钠

    2016-01-01

    Objective To estimate the percentage of infants with large birth size attributable to excess gestational weight gain (GWG), independent of prepregnancy body mass index, among mothers with preexisting diabetes mellitus (PDM). Study design We analyzed 2004–2008 Florida linked birth certificate and maternal hospital discharge data of live, term (37–41 weeks) singleton deliveries (N = 641,857). We calculated prevalence of large-for-gestational age (LGA) (birth weight-for-gestational age ≥ 90th percentile) and macrosomia (birth weight > 4500 g) by GWG categories (inadequate, appropriate, or excess). We used multivariable logistic regression to estimate the relative risk (RR) of large birth size associated with excess compared to appropriate GWG among mothers with PDM. We then estimated the population attributable fraction (PAF) of large birth size due to excess GWG among mothers with PDM (n = 4427). Results Regardless of diabetes status, half of mothers (51.2%) gained weight in excess of recommendations. Large birth size was higher in infants of mothers with PDM than in infants of mothers without diabetes (28.8% versus 9.4% for LGA, 5.8% versus 0.9% for macrosomia). Among women with PDM, the adjusted RR of having an LGA infant was 1.7 (95% CI 1.5, 1.9) for women with excess GWG compared to those with appropriate gain; the PAF was 27.7% (95% CI 22.0, 33.3). For macrosomia, the adjusted RR associated with excess GWG was 2.1 (95% CI 1.5, 2.9) and the PAF was 38.6% (95% CI 24.9, 52.4). Conclusion Preventing excess GWG may avert over one-third of macrosomic term infants of mothers with PDM. Effective strategies to prevent excess GWG are needed. PMID:27539071

    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 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.

    Full Text Available Background: The aim of study was to compare the serum level of magnesium in mothers having low birth weight with those having normal birth weight neonates. Methods: In a case-control study, women who delivered low birth weight neonate (cases, compared with normal birth weight (controls in serum concentration of magnesium. Blood samples collected within 24 h after delivery. Concentration of magnesium assessed by standard atomic absorption spectro-photometry. Multiple linear regression analysis was performed to control of potential confounding variables. Results: A total of 116 mothers (67 cases and 49 control were studied. Mothers in two groups did not differ in age, body mass index, and socioeconomic or demographic factors. Maternal magnesium concentration did not differ between two groups 0.86 ± 0.11 m.mol/l versus 0.94 ± 0.22 m.mol/l respectively ( P = 0.09. Conclusion: There is no significant difference between serum magnesium levels of low birth weight infants′ mother and normal weight infants′ mother.

    Full Text Available According to the World Health Organization (WHO definition, infants with birth weights of less than 2,500 grams are classified as low birth weight (LBW. LBW is a sensitive indicator for predicting the chances of both infant survival and healthy childhood growth and development, and it also reflects the present and past health status of the mother. LBW constitutes an important factor affecting neonatal mortality and morbidity.Objective: To find the incidence of low birth weight babies and its determinants Materials and methods: Present study was a cross sectional type. All mothers delivering live born singleton neonate in study place (Postnatal ward of Rohilkhand Medical College and hospital were interviewed with pretested, predesigned schedule. Statistical analysis was done using SPSS version 21software and chi square test, OR etc.Results: Overall incidence of LBW was 20% and mean birth weight was 2776.85 + 383.6 gm LBW was found to be more common in the rural population and poor educational status. A higher incidence of LBW was seen in mothers with inadequate diet and those who were anaemic. Conclusion: Low birth weight still poses a fair problem in our perspective, and when we cannot control ethnic factors like height, or do a drastic socio-economic upliftment, some basic factors, like good ANC care, correcting anemia, and above all motivating the mother to follow some habits in the ANC period like adequate consumption of food and adequate rest, institutional deliveries shall take a long way forward in addressing the problem.

    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. Conclusions The presented study suggests that exposure to PM2.5 during the last month of pregnancy contributes to risks for lower birth weight and preterm birth in

    Full Text Available Background: Growth is one of the most important indices in child health. The best and most effective way to investigate child health is measuring the physical growth indices such as weight, height and head circumference. Among these measures, weight growth is the simplest and the most effective way to determine child growth status. Weight trend at a given age is the result of cumulative growth experience, whereas growth velocity represents what is happening at the time. Methods: This longitudinal study was conducted among 606 children repeatedly measured from birth until 2 years of age. We used linear mixed model to analyze repeated measures and to determine factors affecting the growth trajectory. LOWESS smooth curve was used to draw velocity curves. Results: Gender, child rank, birth status and feeding mode had a significant effect on weight trajectory. Boys had higher weight during the study. Infants with exclusive breast feeding had higher weight than other infants. Boys had higher growth velocity up to age 6 month. Breast fed infants had higher growth velocity up to 6 month, but thereafter the velocity was higher in other infants. Conclusions: Many of the studies have investigated child growth, but most of them used cross-sectional design. In this study, we used longitudinal method to determine effective factors on weight trend in children from birth until 2-year-old. The effects of perinatal factors on further growth should be considered for prevention of growth disorders and their late complications.
