    Fetal and extrauterine life form a continuum during which human growth and development are affected by genetic, environmental, and social factors. Perinatal mortality is influenced by prenatal, maternal, and fetal conditions and by circumstances surrounding delivery. The majority of infants deaths and developmental disorders are due to disorders relating to prematurity and unspecified low birth weight (LBW), as well as maternal complications of pregnancy and congenital malformations (chromoso...

    Full Text Available Objective: The goal of this study was to identify the risk factors of retinopathy of prematurity (ROP in neonatal intensive care unit in preterm infants born with birth weight 1000-2000g or at gestational age less than 34 weeks. Material & Methods: From August 2000 to December 2001, 50 preterm newborn infants with birth weights less than 2000 g or gestational age less than 34 weeks admitted to the NICU were studied. Newborn infants with birth weight between 1200-2000g who received more than 6 hours oxygen and newborn infants with birth weight 1000-1200 g regardless of oxygen therapy, who survived until 4 weeks postnatal, were enrolled and followed. Patients underwent indirect ophthalmologic examination by two ophthalmologists between 4-8 weeks post partum. The newborn infants who had ROP were assigned to case group and those without ROP to control group, both groups were reexamined every 2-4 weeks or according to international classification of retinopathy of prematurity (ICROP advice. Findings: Fifty newborn infants, 36 (72% in control group, 14 (28% in case group, were studied. Gestational age and birth weight of the patients with ROP were significantly lower than those of control group. Duration of oxygen therapy, hyperoxia, acidosis, hypercarbia, hypocarbia and phototherapy are suggested as risk factors contributing to ROP. Conclusion: The results of this study demonstrate that the ROP frequency remains elevated among premature and very low birth weight infants. Infants at risk for ROP should have screening eye examinations and proper treatment.

    Full Text Available OBJECTIVE: To assess vitamin E levels in the breast milk, analyzing the prematurity and the birth weight influence in α-tocopherol concentration of colostrum milk. METHODS: Cross-sectional study, in which the colostrum was collected from 93 nursing mothers in a public maternity of Natal, Rio Grande do Norte, Northeast Brazil. The newborns were classified based on gestational age and birth weight. The analysis of α-tocopherol in the milk was carried out by high performance liquid chromatography. RESULTS: The α-tocopherol concentration in the colostrum of lactating women whose children were born at term was 1,093.6±532.4µg/dL; for preterm infants, the concentration was 1,321.6±708.5µg/dL (p=0.109. In the preterm group, the α-tocopherol concentration in the colostrum of lactating women whose children were born with low and normal birth weight was 1,316.0±790.7 and 1,327.2±655.0µg/dL, respectively (p=0.971. In the term group, the α-tocopherol levels were higher in mothers of children with birth weight >4000g, being 1,821.0±575.4µg/dL, compared to 869.5±532.1µg/dL and 1,039.6±477.5µg/dL with low and adequate birth weight, respectively (p>0.05. CONCLUSIONS: Prematurity did not influence α-tocopherol levels in the colostrum milk. Mothers who had macrossomic term neonates presented increased α-tocopherol levels. These results indicate that birth weight can influence α-tocopherol leves in the colostrum milk.

    Full Text Available OBJECTIVE: The relationship between weight loss and mortality has important clinical and public health significance but has proved to be complex. Evidence is mixed and particularly limited on the association between weight loss in mid-life and premature death (i.e. before 65 years of age, a small albeit important segment of total mortality. We aimed to study the association between midlife weight change and mortality accounting for health and lifestyle characteristics, and also considering potential bias due to preexisting chronic diseases and smoking status. DESIGN: Longitudinal, population-based, 'the 1946 British' birth cohort study. SUBJECTS AND MEASURES: In 2750 men and women, mortality from age 53 through 65 years was analyzed according to categories of measured 10 year weight change between 43 and 53 years. Cox's hazard ratios (HR were progressively adjusted for socio-demographic, lifestyle and health characteristics. RESULTS: Nearly 20% of participants lost weight and over 50% gained 5 kg or more in midlife. There were 164 deaths. Compared to those who gained between 2 and 5 kg, those who lost 5 kg or more had an increased risk of premature death independently of midlife physical activity, socio-economic circumstances and educational attainment. This association was unaltered when highest weight loss (lost more than 15 Kg (p = 0.04 and early deaths were excluded (p<0.001, but was no longer significant after adjustment for cardiovascular risk factors and health status (HR = 1.8; 95% CI: 0.9 to 3.5. CONCLUSION: The inverse association between weight loss in midlife and higher risk of premature death may be explained by vascular risk factors and ill health. In consideration of the burden of premature death, closer monitoring of weight loss in mid-life is warranted.

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

  11. Effect of low lead exposure on gestational age, birth weight and premature rupture of the membrane

    International Nuclear Information System (INIS)

    Objective: To find out the effect of prenatal exposure to low lead from cosmetics on gestational age, premature rupture of the membrane and birth weight. Methods: The study was carried out in the mountainous Aseer region, Southwest of Saudi Arabia where the air is thought to be clean and free of lead pollution due to the absence of petroleum smelting and other heavy industries. The region is famous as a holiday resort for tourists from Arabia and the gulf countries. All 176 pregnant women included in the study were of singleton pregnancies of gestational age 27 weeks or more who attended the antenatal outpatient clinic of the main maternity hospital. On the day of delivery 4 milliliters of venous blood from each singleton parturient was placed in a heparinized non-silica containing tube and stored at -20 deg. C prior to analysis. Results: Ninety-four (70.1%) women out of 134 had maternal blood lead concentration 200 mu g/L. The mean difference in gestational age was 10.5 days, showing a non significant difference (P=0.152). Ninety-three women (72.7%) out of a total of 128 who had blood lead concentration 200 mu g/L gave birth to infants weighing an average of 2.99 kg. The mean difference was 0.12 kg which is non-significant (P=0.261). Regarding premature rupture of the membrane a total of 127 women with maternal blood lead levels above 200 mu g/L showed no significant differences (P=0.64). The Chi-square test of the relationship between the birth weight (kg) and the levels of blood lead below 150 mu g/L was not significant while the relationship between the birth weight (kg) and the levels of blood lead above 200 mu g/L resulted in very slight differences in the values of infants' birth weight. Conclusion: The detected low lead exposures from cosmetics does not produce statistically significant effects on the three pregnancy outcomes; gestational age, premature rupture of the membrane or birth weight. However, the importance of low lead exposure from the 100% lead

    Periodontitis is a destructive inflammatory disease of the supporting tissues of the teeth and is caused by specific microorganisms or a group of specific microorganisms. Association of periodontal infection with organ systems like cardiovascular system, endocrine system, reproductive system, and respiratory system makes periodontal infection a complex multiphase disease. Inflamed periodontal tissues produce significant amounts of pro-inflammatory cytokines, mainly interleukin 1 beta (IL-1β), IL-6, prostaglandin E2 (PGE2), and tumor necrosis factor alpha (TNF-α), which may have systemic effects on the host. Low birth weight, defined as birth weight less than 2500 g, continues to be a significant public health issue in both developed and developing countries. Research suggests that the bacteria that cause inflammation in the gums can actually get into the bloodstream and target the fetus, potentially leading to premature labor and low birth weight (PLBW) babies. One reasonable mechanism for this is the deleterious effect of endotoxin released from gram-negative bacteria responsible for periodontal disease. Hence, periodontal disease appears to be an independent risk factor for PLBW and there is a need to expand preventive measures for pregnant women in coordination with the gynecological and dental professions.

    Fluconazole is an effective agent for prophylaxis of invasive candidiasis in premature infants. The objective of this study was to characterize the population pharmacokinetics (PK) and dosing requirements of fluconazole in infants with birth weights of weight received intravenous (i.v.) or oral fluconazole at 6 mg/kg of body weight twice weekly. Fluconazole plasma concentrations from samples obtained by either scheduled or scavenged sampling were measured using a liquid chromatography-tandem mass spectrometry assay. Population PK analysis was conducted using NONMEM 7.2. Population PK parameters were allometrically scaled by body weight. Covariates were evaluated by univariable screening followed by multivariable assessment. Fluconazole exposures were simulated in premature infants using the final PK model. A population PK model was developed from 141 infants using 604 plasma samples. Plasma fluconazole PK were best described by a one-compartment model with first-order elimination. Only serum creatinine was an independent predictor for clearance in the final model. The typical population parameter estimate for oral bioavailability in the final model was 99.5%. Scavenged samples did not bias the parameter estimates and were as informative as scheduled samples. Simulations indicated that the study dose maintained fluconazole troughs of >2,000 ng/ml in 80% of simulated infants at week 1 and 59% at week 4 of treatment. Developmental changes in fluconazole clearance are best predicted by serum creatinine in this population. A twice-weekly dose of 6 mg/kg achieves appropriate levels for prevention of invasive candidiasis in extremely premature infants. PMID:27401564

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

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

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

    Premature birth has been associated with a number of adverse maternal psychological outcomes that include depression, anxiety, and trauma as well as adverse effects on maternal coping ability and parenting style. Infants and children who were premature are more likely to have poorer cognitive and developmental functioning and, thus, may be harder to parent. In response to these findings, there have been a number of educational and behavioral interventions developed that target maternal psychological functioning, parenting and aspects of the parent-infant relationship. Since the last comprehensive review of this topic in 2002, there have been a significant number of developments in the quality of the studies conducted and the theoretical models that address the experience of parents of premature infants. In the current review, eighteen new interventions were identified and grouped into four categories based on treatment length and the target of the intervention. Findings suggest a trend towards early, brief interventions that are theoretically based, specifically target parent trauma, and utilize cognitive behavioral techniques. Although it is difficult to generalize study findings, conclusions from the review suggest that targeted interventions may have positive effects on both maternal and infant outcomes. PMID:24532861

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

    Airway injury may occur during the use of any instrumentation in premature infants. A surgical approach for the treatment of lung perforation in extremely low-birth-weight infants has been recommended in the past. Here, we present a case of lung perforation in an ex-28-week, 730-g premature infant, who sustained lung perforation, secondary to an 8-Fr suction catheter used to administer surfactant, in which the broken catheter was retained in the airway. Following removal of catheter by endoscopy, tension pneumothorax had occurred. Attempts were made to treat the patient with single chest tube, unfortunately as it was not efficacious, the second one was placed on the ipsilateral side of hemithorax and the patient recovered without further surgery.

    Full Text Available Pur po se: Retinopathy of prematurity (ROP is a proliferative vascular disease which affects premature newborns and occurs during vessel development. The pathogenesis of ROP is complex and includes oxidative damage to the developing retina. The aim of this study was to evaluate the relationship of ROP with serum vitamin A levels and clinical parameters in infants with a gestational age of ≤32 weeks and birth weight of ≤1500 grams. Ma te ri al and Met hod: Newborns admitted to Newborn Intensive Care Unit within the first 24 hours of life, with gestational age ≤ 32 weeks, birth weight ≤1500 grams, without any major congenital anomalies, inborn error of metabolism or prior history of blood/blood products transfusion were included in the study. The patients were divided into two groups, ROP (+ and ROP (-, according to the presence of ROP at any stage. Serum vitamin A levels and gender, type of delivery, birth weight, gestational age, duration of hospitalization and oxygen supply, multiple gestation, preeclampsia, PDA, sepsis and intraventricular hemorrhage of the groups were compared with Mann-Whitney U and chi-square tests. Re sults: The mean gestational age of these infants was 29.2±2.0 weeks and the mean birth weight was 1287±197 grams. ROP was diagnosed in 48% of infants and the mean serum vitamin A level was 0.56±0.45 μmol/L. In 44 cases (84%, vitamin A level was determined low (<0.7 μmol/L and was extremely low (<0.35 μmol/L in 17 cases (32.7%. There was no significant difference between the ROP (+ and ROP (- groups in terms of vitamin A levels. There was a statistically significant difference between the groups in terms of birth weight, gestational age, multiple gestation, duration of hospitalization and oxygen supply. Dis cus si on: Our results suggest that low birth weight, small gestational age, duration of hospitalization, oxygen exposure time and multiple gestation may increase the risk of ROP, while serum vitamin A level

    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.

    Full Text Available Introduction: One of the common problems in neonatal period is jaundice that occurs in the first week of birth in 60% of term and 80% of preterm neonates. In preterm newborn hyperbilirubinaemia is higher, persistent, longer, and more likely to be associated with neurological injury than term neonates. The purpose of this study was to determine Prophylactic effect of zinc sulphate on hyperbilirubinemia in premature very low birth weight neonates. Method and Material: Sixty Newborns who admitted in our NICU which had inclusion criteria were eligible in this trial. Included neonates were randomly placed in two groups (case and control and before intervention the total serum bilirubin (TSB was measured at second day. The participant received either 20 mg of zinc sulfate or placebo through NG-tube divided in two doses till day seven of age. Then total and indirect bilirubin was measured at 3ed, 5th and 7th day of life. If any of newborns in duration of hospitalization develop clinical jaundice, after assessment of bilirubin, need for phototherapy was evaluated based on phototherapy and exchange schedule as described by the American Academy of Pediatrics guidelines. The termination point of phototherapy was defined as a bilirubin level less than 50 percent of starting point. After gathering Data, they were analyzed using SPSS software (version 11.5 and T-test, Chi-square and repeated measurement tests. Results: Seventy eight patients enrolled in this trial that 18 cases were excluded and the remaining cases divided into two equal groups (N=30 in each group. Demographic condition was similar in two groups. There were no different between two groups in decreasing total serum bilirubin and duration of phototherapy. Conclusion: This study showed that zinc sulfate has no preventing effective in hyperbilirubinemia in preterm very low birth weight neonates. It has also no effect on duration of phototherapy.

  3. Lung mechanics and high-resolution computed tomography of the chest in very low birth weight premature infants

    International Nuclear Information System (INIS)

    Premature infant lung development may be affected by lung injuries during the first few weeks of life. Lung injuries have been associated with changes in lung mechanics. The objective is to evaluate an association between lung mechanics and lung structural alterations in very low birth weight infants (birth weight less than 1500 g). The design presents a cross-sectional evaluation of pulmonary mechanics (lung compliance and lung resistance) and high resolution computed tomography of the chest at the time of discharge, in 86 very low birth weight infants born at Instituto Fernandes Figueira, a tertiary public health care institution in Rio de Janeiro, Brazil. Lung compliance and resistance were measured during quiet sleep. High resolution computed tomography was performed using Pro Speed-S equipment. Statistical analysis was performed by means of variance analysis (ANOVA/ Kruskal Wallis). The significance level was set at 0.05. The results showed abnormal values for both lung compliance and lung resistance were found in 34 babies (43%), whereas 20 (23.3%) had normal values for both lung compliance and lung resistance. The mean lung compliance and lung resistance for the group were respectively 1.30 ml/cm H2 O/kg and 63.7 cm H2 O/l/s. Lung alterations were found via high-resolution computed tomography in 62 (72%) infants. Most infants showed more than one abnormality, and these were described as ground glass opacity, parenchymal bands, atelectasis and bubble/cyst. The mean compliance values for infants with normal (1.49 ml/cm H2 O/kg) high resolution computed tomography, 1 or 2 abnormalities (1.31 ml/cm H2 O/kg) and 3 or more abnormalities (1.16 ml/cm H2 O/kg) were significantly different (p = 0.015). Our data were insufficient to find any association between lung resistance and the number of alterations via high-resolution computed tomography. The conclusion was that the results show high prevalence of lung functional and tomographic abnormalities in asymptomatic

    Full Text Available Introduction: Retinopathy of prematurity (ROP is the most common cause of childhood blindness. The risk of ROP is increased in premature infants with very low birth weights, as the most common risk factors for ROP are low birth weight and early periods of gestation. The aim of this study was to evaluate the risk factors and the incidence of ROP among premature infants weighing under 1500 g upon delivery. Materials and Methods: Between August 2010 and December 2012, 84 patients followed up in the neonatal intensive care unit who were under 32 weeks old at birth and under 1500 g at birth were included in this study. Patients were separated into two groups: those with retinopathy and those without. Then the risk factors were compared between groups. Results: Mean gestational age and birth weight of the patients in group 1 and group 2 were 27.86±2.0 weeks, 1,146.66±278.58 g and 29.08±1.96 weeks, 1,289.36±74.77 g, respectively. Retinopathy was detected in 44% of the patients and of them 7.1% were treated for severe retinopathy. We determined that early periods of gestation (p=0.007, low birth weight (p=0.007, being transported (p=0.01, intraventricular hemorrhage (p=0.04, prolonged ventilation (p=0.006, prolonged oxygen administration (p=0.01, and blood transfusion (p=0.01 were statistically significant risk factors in patients with retinopathy. Conclusions: ROP has been recognized as one of the most important causes of childhood blindness in the world. However blindness is preventable if patients are diagnosed early and treated properly. Thus, it is important to determine the risk factors for ROP.

    Full Text Available Few studies have investigated the duration of breastfeeding among premature infants born with very low birth weight. The prevalence of exclusive breastfeeding among very low birth weight premature infants at a university hospital in Londrina Paraná State, Brazil and the identification of factors related to breastfeeding practice were determined. Current quantitative and analytic retrospective study analyzed the medical records, attendance reports and interviews of 54 mother-infant binomials. Breastfeeding was prevalent in 90% of infants, of which 50% were exclusively breastfed, at hospital discharge. However, 51% were weaned before their sixth month. The statistical analysis showed a positive association between breastfeeding and do not working mothers outside the home, cesarean delivery, positive previous experience in breastfeeding and gestational age at birth over 33 weeks. MF prevalence in the specific population NBVLW infants reinforce the notion that breastfeeding preterm infants, albeit challenging, may be carried out with the appropriate support of the mother-child binomial.

    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

    The categories of low birth weigth infants, social vs. racial factors, factors increasing the risk of low birth weight, prevention of low birth weight, social factors in the development of low birth weight children, the influence of social factors vs. other variables, and implications for management are reviewed. In 1948 the World Health Assembly designated children who were born weighing 2500 g or less as "immature" and further stated that a liveborn infant with a period of gestation of less than 37 weeks or specified as "premature" may be considered as the equivalent of an immature event. In 1961 it was recommended that babies weighing 2500 g or less should no longer be referred to as being "premature" and that the concept of "prematurity" in the definition should give way to that of "low birth weight." Intrauterine growth curves for liveborn males and females were devised from data on birth weight and gestational age. Infants born prior to 37 completed weeks of gestation whose weight lies between the 10th and 90th percentiles on such curves may be called preterm with a weight appropriate for gestational age (AGA), whereas infants born after any length of gestation whose birth weight is at or below the 10th percentile may be named hypotrophic or small for gestational age (SGA). On a worldwide scale it has been estimated that about 22 million low birth weight babies, representing roughly 1/6 of all births, are born alive each day. Only about 1 million of them (mostly preterm) are born in developed countries; of the 21 million born in developing areas, roughly 16 million are SGA full-term and not preterm babies. Socioeconomic status appears as 1 of the most important dterminants of the ultimate level of brain function in children of low birth weight, and this is true with respect to neurologic, psychologic, and educational outcome. Social class also has an indirect effect through birth weight, frequency of perinatal brain injury, and other biological variables as

Methods: The clinical data of 217 premature infants born in the hospital from January 2008 to December 2009 were analyzed retrospectively. Results: The incidence of complication and mortality of premature infants were 43.8% and 2. 3%, respectively; the premature infants less than 32 gestational weeks or birth weight < 1 500 g had high incidence of complication and high mortality; the incidences of complications ( including hypoxic ischemic encephalopathy, asphyxia and respiratory distress syndrome) and mortality of premature infants showed a decreasing trend with fetal age and the increase of birth weight. Conclusion: Enhancing pregnant health care before delivery, prolonging fetal age as far as possible,promoting fetal lung maturity, preventing neonatal asphyxia and strengthening the monitoring on low birth weight infants may reduce the incidence of complication and mortality of premature infants.

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

    1981-05-01

    Data from six infant welfare centres in the vicinity of Amsterdam airport were analysed. Birth weights of 902 infants were related to aircraft noise levels to which the mother was exposed in pregnancy. The analysis was restricted to deliveries in hospital, single births and mothers aged 20-34 years. In high noise areas the mean birth weight was 69 g lower than in low noise areas. Of the infants in high noise areas 24% had a birth weight less than 3000 g, compared with 18% in low noise areas. In the analysis the effect of sex of the infant, birth order and to some extent socio-economic status were taken into account. An effect of smoking seemed unlikely. The results, together with existing knowledge, give some suggestion that aircraft noise can decrease birth weight.

    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.

    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.

    Premature infants are considered a high-risk population for developing cognitive dysfunction. Studies have indicated lower cognitive performance among elementary school children born prematurely. We focused on cognitive functioning of such adolescents. This age was chosen because of its critical importance in the development of the individual. 50 adolescents aged 14-16 years born prematurely were compared with 50 born at full-term and matched for gender, age and socioeconomic status. All subjects attended regular schools and did not suffer severe neurological disorders. Cognitive functioning was measured by the Bender-Visual Motor Gestalt Test and by 3 subtests from the Wechsler Intelligence Scale for Children (revised WISC-R test). Results revealed that prematurely born adolescents scored lower than those born at term on all measures of cognitive performance. The results are discussed in terms of their developmental meaning and of therapy for the prematurely born. PMID:11419040

    and divided into two categories according to the relative risk of low birth weight and/or preterm prevalence. Sixteen specific groups were created from crossing the four variables into two categories. Low birth weight and/or preterm prevalence per number of prenatal visits and the relative risk were calculated for all sixteen groups. RESULTS: For all sixteen groups, the higher the number of prenatal visits the lower the prevalence of low birth weight and/or prematurity. Additionally, there was an overall reduction of the difference of low birth weight and/or preterm prevalence among the 16 groups from 14% to 4% with an increase from 0-3 to 7 visits or more. CONCLUSIONS: Due to the current infant mortality composition in the state of Sao Paulo, increasing the number of prenatal visits and accessibility of women at risk would probably lead to a reduction in intrauterine growth retardation, prematurity, low birth weight and deaths associated to conditions originated in the perinatal period.

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

    Full Text Available Introduction. Retinopathy of prematurity is a disease of the eye which affects the blood vessels of the retina and represents the most important cause of blindness and low vision in children worldwide. There are many risk factors given by birth and parameters of general health status that may influence this disease. The aim of this study was to investigate the significance of the factors given by birth and use of oxygen in relation to the development of premature retinopathy. Material and Methods. A two-year-long prospective study was done at the Institute for Child and Youth Health Care of Vojvodina. In this study the following parameters were examined: weight, gestational age as a factor given by birth and parameters of oxygenotherapy - the number of days on oxygenotherapy and the number of days of mechanical ventilation. The findings on the eye fundus were also taken into consideration. Results. The test results suggest that the gestational age is the most important factor given by birth which determines the possibility of development of premature retinopathy. Conclusion. In fact, the most important risk factor for the development of premature retinopathy is premature birth.

    Full Text Available Abstract Background Malaria has a negative effect on pregnancy outcome, causing low birth weight, premature birth and stillbirths, particularly in areas with high malaria transmission. In Rwanda, malaria transmission intensity ranges from high to nil, probably associated with variable altitudes. Overall, the incidence decreased over the last six years (2002–2007. Therefore, the impact of malaria on birth outcomes is also expected to vary over time and space. Methods Obstetric indicators (birth weight and pregnancy outcome and malaria incidence were compared and analyzed to their association over time (2002–2007 and space. Birth data from 12,526 deliveries were collected from maternity registers of 11 different primary health centers located in different malaria endemic areas. Malaria data for the same communities were collected from the National Malaria Control Programme. Associations were sought with mixed effects models and logistic regression. Results In all health centres, a significant increase of birth weight over the years was observed (p Conclusion In Rwanda, birth weight and pregnancy outcome are not directly influenced by malaria, which is in contrast to many other studied areas. Although malaria incidence overall has declined and mean birth weight increased over the studied period, no direct association was found between the two. Socio-economic factors and improved nutrition could be responsible for birth weight changes in recent years.

    2014-04-01

    Full Text Available Objective: Epidemiological research often seeks to identify a causal relationship between the risk factors and the disease. Earlier researches suggest that mother age, her weight at last menstrual period, race, the number of physician visit during the first trimester of pregnancy, may affect on her neonate birth weight. Mechanisms of mother lifestyle characteristics on her neonate weight are intricately complicated. These mechanisms, however, can be easily interpreted through an appropriate mathematical relationship. The present study aims to identify the factors of mother's lifestyle characteristics which have statistical significant effects on her neonate birth weight based on statistical (or probabilistic modeling. Materials and Methods: The present study is based on the secondary data collected at Baystate Medical Center, Springfield, Massachusetts during 1986. It was a routine data set. There was not any specific setting. Study subjects were 189 mothers, 59 of which had low birth weight babies and 130 of which had normal birth weight babies. Joint generalized linear log-normal statistical modeling of mean and variance is used. Results: The present analysis identifies that mother age (p= 0.063, her weight at last menstrual period (p= 0.019, race (p= 0.017, p= 022, smoking status (p= 0.014, history of premature labor (p= 0.008, history of hypertension (p= 0.031, 0.039 and presence of uterine irritability (p= 0.002 are statistically significant on her neonate birth weight. It has been detected that the variance of neonatal birth weight is non-constant, which invites the present study. Conclusion: Impacts of mother's lifestyle characteristics on her neonate weight are explained based on mathematical relationships. This analysis supports many earlier research findings. However, the present analysis also has identified many additional casual factors that have explained the mean and variance of neonatal birth weight, which was not reported by the

  10. Meconium microbiome analysis identifies bacteria correlated with premature birth.

    Directory of Open Access Journals (Sweden)

    Alexandria N Ardissone

    Full Text Available Preterm birth is the second leading cause of death in children under the age of five years worldwide, but the etiology of many cases remains enigmatic. The dogma that the fetus resides in a sterile environment is being challenged by recent findings and the question has arisen whether microbes that colonize the fetus may be related to preterm birth. It has been posited that meconium reflects the in-utero microbial environment. In this study, correlations between fetal intestinal bacteria from meconium and gestational age were examined in order to suggest underlying mechanisms that may contribute to preterm birth.Meconium from 52 infants ranging in gestational age from 23 to 41 weeks was collected, the DNA extracted, and 16S rRNA analysis performed. Resulting taxa of microbes were correlated to clinical variables and also compared to previous studies of amniotic fluid and other human microbiome niches.Increased detection of bacterial 16S rRNA in meconium of infants of <33 weeks gestational age was observed. Approximately 61·1% of reads sequenced were classified to genera that have been reported in amniotic fluid. Gestational age had the largest influence on microbial community structure (R = 0·161; p = 0·029, while mode of delivery (C-section versus vaginal delivery had an effect as well (R = 0·100; p = 0·044. Enterobacter, Enterococcus, Lactobacillus, Photorhabdus, and Tannerella, were negatively correlated with gestational age and have been reported to incite inflammatory responses, suggesting a causative role in premature birth.This provides the first evidence to support the hypothesis that the fetal intestinal microbiome derived from swallowed amniotic fluid may be involved in the inflammatory response that leads to premature birth.

    PURPOSE: To compare the frequency and severity of retinopathy of prematurity (ROP among singleton and multiple-birth neonates referred to Farabi Eye Hospital, Tehran-Iran. METHODS: In this retrospective study, records of 99 consecutive neonates from multiple-gestation pregnancies including 68 twins, 26 triplets and 5 quadruplets who were screened for ROP from 2002 to 2004 were reviewed. The frequency, severity and risk factors for ROP were determined and compared to a group of singletons who were matched in terms of gender, birth weight (BW, gestational age (GA, oxygen therapy, respiratory distress syndrome, blood transfusion, sepsis and phototherapy. RESULTS: ROP was present in 12.1% of multiple-birth neonates as compared to 15.1% of singletons (P=0.53. Threshold ROP was present in 6.1% of multiple-birth neonates versus 7.1% of singletons (P=0.62. ROP was detected in 60% of quadruplets versus 9.6% of twins and triplets; threshold disease was observed in 40% of quadruplets as compared to 4.2% of twins and triplets (P < 0.03.

    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.

    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.

    A case-control study was made in Gunma Prefecture of 1,390 mothers of babies born weighing 2,500 grams or less and an equal number of mothers of 3,000-up to-4,000 gram babies matched by place and month of birth. A correlation was found between low-birth-weight babies and maternal age, stature, menstrual history and past history. The mother's occupation, educational career, smoking habits, amount of sleep each day, date of issue of the Mother's Handbook and the number of the periodical health examinations received can be listed as socio-medical factors. Bleeding and lower abdominal pain during pregnancy, anemia and toxemia of pregnancy are found as prenatal factors. Low-birth-weight babies are found to be correlated with multiple pregnancy, breech presentation, placenta previa and premature separation of the placenta, also. PMID:6747384

  17. Can low birth weight be prevented?

    Brown, S S

    1985-01-01

    In the US low birth weight is the major factor associated with the death of infants in the 1st 4 weeks of life. Over the 1st 1/2 of the century, infant mortality declined from about 100 to about 30 deaths/1000 live births. But most of this decline has been attributed to decreases in the rate of postneonatal mortality (deaths from 28 days to the 1st birthday). Declines in low-birth-weight rates have been concentrated among babies whose mothers are at lowest risk. Low-birth-weight infants who do survive face increased risk of a range of childhood illnesses and developmental problems. The problem of low birth weight is also important for economic reasons. More than US$1.5 billion is spent annually on neonatal intensive care services in the US. Teenage mothers, blacks, and women of low socioeconomic status are at high risk of having a baby of low birth weight. Pregnancy intervals of shorter than 6 months, a variety of chronic illnesses, multiple pregnancies, smoking, and failure to obtain, or delay in initiating, prenatal care also increase the risk that a woman will have a low-birth-weight baby. The Institute of Medicine committee has outlined an approach to the prevention of low birth weight that emphasizes 5 principal points: 1) pre-pregnancy identification of high risk women with more and improved counseling, health education, and family planning services; 2) increase the availability and quality of early prenatal care; 3) strengthen and expand the content of prenatal services; 4) mount a public information campaign aimed at preventing low-birth-weight; 5) research. If these measures are implemented, it has been estimated that US$41 million can be saved each year from the US$188 million the government spends annually for the care of low-birth-weight babies. The federal government must take a leadership role if these measures are to be successful. PMID:3842660

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

  1. How Neighborhood Disadvantage Reduces Birth Weight

    Directory of Open Access Journals (Sweden)

    Emily Moiduddin

    2008-06-01

    Full Text Available In this analysis we connect structural neighborhood conditions to birth outcomes through their intermediate effects on mothers’ perceptions of neighborhood danger and their tendency to abuse substances during pregnancy. We hypothesize that neighborhood poverty and racial/ethnic concentration combine to produce environments that mothers perceive as unsafe, thereby increasing the likelihood of negative coping behaviors (substance abuse. We expect these behaviors, in turn, to produce lower birth weights. Using data from the Fragile Families and Child Wellbeing Study, a survey of a cohort of children born between 1998 and 2000 and their mothers in large cities in the United States, we find little evidence to suggest that neighborhood circumstances have strong, direct effects on birth weight. Living in a neighborhood with more foreigners had a positive effect on birth weight. To the extent that neighborhood conditions influence birth weight, the effect mainly occurs through an association with perceived neighborhood danger and subsequent negative coping behaviors. Poverty and racial/ethnic concentration increase a mother’s sense that her neighborhood is unsafe. The perception of an unsafe neighborhood, in turn, associates with a greater likelihood of smoking cigarettes and using illegal drugs, and these behaviors have strong and significant effects in reducing birth weight. However, demographic characteristics, rather than perceived danger or substance abuse, mediate the influence of neighborhood characteristics on birth weight.

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

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

    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.

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.

  2. Emotional reactions of mothers facing premature births: study of 100 mother-infant dyads 32 gestational weeks.

    Julien Eutrope

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

    Full Text Available 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 Background Candida colonization is a major risk factor for invasive candidiasis in premature infants in the neonatal intensive care unit (NICU. Objectives The purpose of this study was to determine the rate, risk factors, and sources of colonization in low birth weight (LBW and very low birth weight (VLBW infants in an NICU. Patients and Methods All cases were classified in to 1 of 2 groups: LBW and VLBW. A questionnaire that collected demographic data was completed for each case. Swabs were obtained from the ear, umbilicus, and rectum, as well as catheters, tracheal tubes, and nasogastric tubes. Samples were cultured on Sabouraud dextrose agar. The data were analyzed using SPSS software. A P value < 0.05 was considered significant. Results A total of 102 cases were examined in this study. The mean weight of the infants was 1720 ± 474 gr (range 850 - 2500 gr. Positive Candida cultures were isolated in 19 (31.7% cases in the LBW group and 20 (47.6% cases in the VLBW group. In addition, 36 (35.3% cases showed signs of sepsis. The mortality rate was 1.7% (n = 1. The umbilicus and rectum were the most common sites for Candida colonization in both groups. The analysis also indicated that the duration of hospitalization, prolonged use of corticosteroids, central venous catheters, total parenteral nutrition, and mechanical ventilation were associated with candidiasis infection in VLBW infants while prolonged use of corticosteroids and central venous catheters were major risk factors associated with candidiasis infection in LBW infants. Conclusions These results show that maturity and birth weight are related to a decrease in the risk of developing a candidiasis infection.

    Full Text Available To determine the incidence and risk factors of nephrocalcinosis in preterm infants, we studied in a prospectively 64 preterm infants of birth weight :5 1500 g from February 2006 to November 2007. Data were collected on gestation, birth weight, gender and family history of renal calculi, respiratory support, and use of nephrotoxic drugs. The parameters of mineral meta-bolism were assessed in blood and spot urine samples at the end of 2 nd and 4 th weeks of age. Forty-nine babies completed the study, and nephrocalcinosis was observed in 13 (26.5% babies and was bilateral in 7 (14.3% infants. The mean age of diagnosis of nephrocalcinosis was 52.58 days (range 30-123 days. Gestational age, birth weight, and sex were not significantly associated with increased risk of nephrocalcinosis. The mean duration of ventilation was significantly less in babies with than without nephrocalcinosis (P= 0.020, and the mean levels of urine calcium and phosphate at 4 weeks of age, respectively (P= 0.013, P= 0.048. There were also significant diffe-rences in urine calcium/creatinine ratio (P= 0.001, mean plasma levels of calcium at 2 weeks of age (P= 0.047 and plasma levels of phosphate at 4 weeks of age (P= 0.016 between babies with and without nephrocalcinosis. Using logistic regression analysis, family history of renal stone (P= 0.002 and urine calcium/creatinine ratio (P= 0.011 were significant predictors of nephrocalci-nosis. However, there were no significant differences in the length of stay in the intensive care unit, duration of total parenteral nutrition, and duration and cumulative doses of nephrotoxic drugs between these two groups. We conclude that the incidence of nephrocalcinosis was similar in our population to the previous studies. Family history of renal stone and urine calcium/ creatinine ratio are the major risk factors of nephrocalcinosis in very low birth weight neonates.

    Objective. To compare birth weight ratio and birth weight percentile to express infant weight when assessing pregnancy outcome. Study Design. We performed a national cohort study. Birth weight ratio was calculated as the observed birth weight divided by the median birth weight for gestational age. The discriminative ability of birth weight ratio and birth weight percentile to identify infants at risk of perinatal death (fetal death and neonatal death) or adverse pregnancy outcome (perinatal death + severe neonatal morbidity) was compared using the area under the curve. Outcomes were expressed stratified by gestational age at delivery separate for birth weight ratio and birth weight percentile. Results. We studied 1,299,244 pregnant women, with an overall perinatal death rate of 0.62%. Birth weight ratio and birth weight percentile have equivalent overall discriminative performance for perinatal death and adverse perinatal outcome. In late preterm infants (33+0–36+6 weeks), birth weight ratio has better discriminative ability than birth weight percentile for perinatal death (0.68 versus 0.63, P  0.01) or adverse pregnancy outcome (0.67 versus 0.60, P < 0.001). Conclusion. Birth weight ratio is a potentially valuable instrument to identify infants at risk of perinatal death and adverse pregnancy outcome and provides several advantages for use in research and clinical practice. Moreover, it allows comparison of groups with different average birth weights. PMID:25197283

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.

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

Objective: This study was undertaken to explore change in birth weights in a period from 1989 to 2007 and any associations thereof. Materials and Methods: All birth records of a private rural hospital spanning two decades (1989-2007 were analyzed for birth weight, age of mother, gender, birth order of the baby, proportion of pre-term babies and low birth weight babies. Results: No change was observed in the average birth weights (average 2.71 kg over the period. Although the birth weight shows some expected variance with the age of mother, it was found to have no relation with the baby′s birth order and gender. The low birth weight proportion is about 24% and shows little difference before and after the series midpoint of year 1998. Conclusion: The birth weights have hardly changed in this population in the two decades.

    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.

    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.

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

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

    Objective: This study was done to determine the role of prematurity and other variables to predict insulin sensitivity in infancy. Subjects and Methods: In this prospective study, 36 preterm appropriate for gestational age (AGA), 11 preterm small for gestational age (SGA), and 17 term SGA included as study cohort and 36 term AGA as control cohort. Detailed anthropometry assessment was performed at birth, 3, 6, and 9 months and at 9 months, fasting plasma glucose and serum insulin was done. Insulin resistance was determined by using homeostasis model assessment version 2. Results: It is found that preterm AGA (mean difference 0.617, 95% confidence interval [CI]; 0.43–0.80, P = 0.0001), preterm SGA (mean difference 0.764, 95% CI; 0.44–1.09, P = 0.0001), and term AGA (mean difference 0.725, 95% CI; 0.49–0.96, P = 0.0001) group had significantly higher insulin resistance than control. There was no significant difference in between preterm SGA and preterm AGA (mean difference 0.147 95% CI; −0.13–0.42, P = 0.927). In multiple regression models, SGA status (β =0.505) was more significant predictor of insulin resistance index than gestational age (β = −0.481), weight-for-length (β =0.315), and ponderal index (β = −0.194). Conclusion: Preterm birth is a risk factor for the future development of insulin resistance which may develop as early as infancy. PMID:27366716

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

    Objective To explore the heart protection in very low birth weight premature infants with respiratory distress syndrome (RDS) after using budesonide combined with pulmonary surfactant (PS) ,and evaluate the therapeutic effect of combination of budesonide and PS. Methods Thirty premature infants with gestational age <34 weeks,birth weight < 1 500 g and RDS within 4 hours after birth were randomly divided into the PS + budesonide group and PS group, who were hospitalized in Maternal and Child Health Hospital of Nanjing form Aug. 2010 to Mar. 2011. PS and budesonide were used in PS + budesonide group (per 70 mg PS adding budesonide 0.25 mg) ,in which PS dose was 70 mg · kg-1,and budesonide dose was 0.25 mg · kg-1. Patients in PS group only used PS,in which dose was 70 mg · kg-1. Tra-cheal inhalation of PS or PS + budesonide was performed in both groups 30 to 60 minutes after births. Serum creatine kinase myocardial isoenzyme (CK - MB) and troponin were detected in both groups in 1 day,7 days and 14 days. Cardiac functions were evaluated by using echocardiography,and the parameters included left ventricular ejection fraction(LVEF) ,right ventricular ejection fraction( RVEF),ratio of peak E velocity and peak A velocity of mitral flow and tricuspid flow( MVE/A and TVE/A) and LV - Tei index. Results CK - MB and troponin in PS + budesonide group were significantly lower than those in the control group on the 14th day(Pa <0.05) ;and LVEF was significantly higher on the 14th day(P<0.05);and RVEF was significantly higher on the 7th day, 14th day(Pa <0. 05). MVE/A and TVE/A were increased in both groups. But,PS + budesonide group had significant differences compared with the PS group of MVE/A on the 14th day( MVE/ A),and TVE/A on the 7th day and 14th day(P, <0.05). LV-Tei index in PS + budesonide group was significantly lower (P<0.05).

  1. The influence of maternal body composition on birth weight.

    LENUS (Irish Health Repository)

    Farah, Nadine

    2012-02-01

    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.

    2012-07-01

    Full Text Available Abstract Background A number of studies have reported on the effects of iron supplementation in low birth weight infants; however, no systematic review of the available evidence has been conducted to date. Hence, we performed a systematic review of the literature to examine the effects of iron supplementation on hematologic iron status, growth, neurodevelopment, and adverse effects in low birth weight/premature infants. Methods We searched the Cochrane Library, Medline, and PubMed for articles reporting on the effects of iron supplementation in low weight infants. The following search terms were used: “preterm born infant(s/children”; “preterm infants”; “prematurely born children” “weight less than 1500 g at birth”; “born prematurely”; “low birth weight infant(s”; “infants born preterm”; “prematurity”; “small-for-gestational age”; “very small gestational age infants”; “iron supplementation”; “iron intake”; “iron supplements”; “ferric and/or ferrous compounds”; and “ferrous sulphate/fumarate/sulfate”. Results A total of 15 studies were identified and included in the systematic review. Supplemental iron was given orally or as an iron-fortified formula in 14/15 studies. The duration of treatment ranged from 1 week to 18 months. Iron supplementation significantly increased hematologic measures of iron status (including hemoglobin, hematocrit, serum ferritin relative to placebo or over time in most studies. All controlled studies that examined iron-deficiency anemia (IDA/ID reported a decreased prevalence of IDA/ID with iron supplementation. Dose dependent decreases in the prevalence of IDA/ID were reported in several studies. Of the 5 studies reporting on growth, none found any significant effect on growth-related parameters (length, height, weight, and head circumference. Only 2 studies reported on neurodevelopment; no marked effects were reported. There were no consistently reported

    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.

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

    Directory of Open Access Journals (Sweden)

    Desiree Yee-Ling Phua

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

    2011-01-01

    Full Text Available Prader-Willi syndrome in the newborn is essentially characterized by marked hypotonia, feeding difficulties, hypogonadism, and possible characteristic facial features. However, diagnosis at this age may be particularly difficult, and dysmorphic features may be subtle or absent. Prematurity can furthermore delay clinical features recognition and typical complications due to preterm birth may contribute to divert the diagnosis. We describe a preterm baby with a complicated perinatal course later diagnosed as PWS.

    Full Text Available Abstract Background Birth size, and particularly birth length, is positively associated with breast cancer risk in adulthood. The objective of this study was to examine whether birth size is associated with survival among breast cancer patients. Methods Information on birth size (weight, length and ponderal index (kg/length (m3 was collected from birth archives for 331 breast cancer patients who were diagnosed at two university hospitals in Norway (Bergen and Trondheim. The patients were followed from the time of diagnosis until death from breast cancer, death from another cause, or to the end of follow-up, and birth size was related to survival, using Cox regression analysis. Results Breast cancer patients with birth length ≥ 52 cm had nearly twice the risk of dying (hazard ratio, 1.92, 95% confidence interval, 1.09-3.41 from breast cancer compared to women with birth length less than 48 cm, after adjustment for place of birth and year of diagnosis. Similar analyses related to birth weight and ponderal index showed no clear association with breast cancer survival. Conclusions Poorer outcome of breast cancer patients with high birth length may reflect effects of factors that stimulate longitudinal growth and simultaneously increase the risk of metastases and fatal outcome. It is possible that the insulin-like growth factor (IGF system is involved in the underlying mechanisms.

    Full Text Available Objective:Neonates with birth weights below 1500 g who were cared for in the neonatal intensive care unit of Fatih University Hospital were retrospectively examined in order to define their rates of morbidity and mortality. Methods: This study was conducted on 72 premature infants divided into two groups: those with birth weights below 1000 g(31 infants and those above 1001 g(41 infants. Data on these infants were recorded and statistically evaluated. Birth weights ranged from 670 g to 1500 g and gestational weeks varied between 25 and 35 weeks. Results:In our study, the mortality rate of infants with extremely low birth weights was 7.6%. Durations of oxygen and antibiotic therapies were found to be significantly longer in the infants with birth weights of 1000 g or less (p < 0.01. The most common diseases in all the groups were retinopathy of prematurity, occurring in 54.2% (n=39; broncho-pulmonary dysplasia (BPD in 51.4% (n=37; and intraventricular hemorrhage (IVH in 34.5% (n=20. Incidence of chronic pulmonary disease and retinopathy of prematurity (ROP was found to be statistically ignifi cant in the infants with birth weights of 1000 g or less (p < 0.01. Conclusion:Because mortality rate is low but rates of ROP, IVH and BPD are high in this unit, risk factors of these diseases hould be well assessed and necessary measures should be taken in order to increase quality of life in the long term for the infants with extremely low birth weights.

    The compelling evidence linking small size at birth with later cardiovascular disease has renewed and amplified a clinical and scientific interest in the determinants of fetal growth. Although the effects of maternal nutrition on fetal growth have been extensively studied, comparatively little is known about the effects of maternofetal hypoxia. This study tested the hypothesis that in highland regions, high altitude rather than maternal economic status is associated with reduced and altered fetal growth by investigating the effects of high altitude versus economic status on birth weight and body shape at birth in Bolivia. Bolivia is geographically and socioeconomically unique. It contains several highland (>3500 m above sea level) and lowland (weight, body length, and head circumference were compared between a high- (n = 100) and low- (n = 100) income region of La Paz (3649 m; largest high-altitude city) and a high- (n = 100) and low- (n = 100) income region of Santa Cruz (437 m; largest low-altitude city). In addition, the frequency distribution across the continuum of birth weights was plotted for babies born from high- and low-income families in La Paz and Santa Cruz. Mean birth weights were lower in babies from La Paz than in babies from Santa Cruz in both high- and low-income groups. The cumulative frequency curve across all compiled birth weights was shifted to the left in babies from La Paz compared with those from Santa Cruz, regardless of economic status. The frequency of low birth weight (head circumference:birth weight ratio. These findings suggest that high altitude rather than economic status is associated with low birth weight and altered body shape at birth in babies from Bolivia. PMID:11264431

    Full Text Available OBJECTIVE: To evaluate intraocular pressure in very low birth weight preterm infants and correlate it with postconceptional age. METHODS: The intraocular pressure in a prospective cohort of very low birth weight premature infants (defined as a birth weight <1,500 g and gestational age <32 weeks admitted to Hospital de Clínicas de Porto Alegre , Brazil was evaluated weekly. The evaluated outcome was the variation in the intraocular pressure following changes in the postconceptional age (defined as the gestational age at birth plus the age in weeks at the time of examination in the weeks following preterm birth. Mixed-effects models were used for the statistical analysis to determine the intraocular pressure variation according to postconceptional age, and means and 10th and 90th percentiles were calculated for the intraocular pressure values. RESULTS: Fifty preterm infants with a mean gestational age of 29.7 ± 1.6 weeks and a mean birth weight of 1,127.7 ± 222.7 g were evaluated. The mean intraocular pressure for the entire cohort considering both eyes was 14.9 ± 4.5 mmHg, and 13.5% of all recorded intraocular pressure values were greater than 20 mmHg. The analysis revealed a mean reduction in the intraocular pressure of 0.29 mmHg for each increase in postconceptional age (p = 0.047; 95% CI: -0.58 to -0.0035. The mean intraocular pressure (P10-P90 decreased from 16.3 mmHg (10.5222.16 at 26.3 weeks to 13.1 mmHg (7.28-18.92 at 37.6 weeks of postconceptional age. CONCLUSIONS: The mean intraocular pressure in very low birth weight preterm infants was 14.9 ± 4.5 mmHg. This value decreased 0.29 mmHg per week as the postconceptional age increased.

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

    2009-03-01

    To identify candidate genes contributing to preterm birth, we examined the existing literature on the association between known disorders of connective tissue synthesis and metabolism and related diseases and prematurity. Our hypothesis was that abnormal matrix metabolism contributes to prematurity by increasing risk of preterm premature rupture of membranes (PPROM) and cervical incompetence. Based on this review, we identified gene mutations inherited by the fetus that could predispose to preterm birth as a result of PPROM. The responsible genes include COL5A1, COL5A2, COL3A1, COL1A1, COL1A2, TNXB, PLOD1, ADAMTS2, CRTAP, LEPRE1 and ZMPSTE24. Marfan syndrome, caused by FBN1 mutations, and polymorphisms in the COL1A1 and TGFB1 genes have been associated with cervical incompetence. We speculate that an analysis of sequence variation at the loci noted above will reveal polymorphisms that may contribute to susceptibility to PPROM and cervical incompetence in the general population.

    2006-08-01

    Full Text Available BACKGROUND: We postulated that during ontogenesis cortical surface area and cerebral volume are related by a scaling law whose exponent gives a quantitative measure of cortical development. We used this approach to investigate the hypothesis that premature termination of the intrauterine environment by preterm birth reduces cortical development in a dose-dependent manner, providing a neural substrate for functional impairment. METHODS AND FINDINGS: We analyzed 274 magnetic resonance images that recorded brain growth from 23 to 48 wk of gestation in 113 extremely preterm infants born at 22 to 29 wk of gestation, 63 of whom underwent neurodevelopmental assessment at a median age of 2 y. Cortical surface area was related to cerebral volume by a scaling law with an exponent of 1.29 (95% confidence interval, 1.25-1.33, which was proportional to later neurodevelopmental impairment. Increasing prematurity and male gender were associated with a lower scaling exponent (p < 0.0001 independent of intrauterine or postnatal somatic growth. CONCLUSIONS: Human brain growth obeys an allometric scaling relation that is disrupted by preterm birth in a dose-dependent, sexually dimorphic fashion that directly parallels the incidence of neurodevelopmental impairments in preterm infants. This result focuses attention on brain growth and cortical development during the weeks following preterm delivery as a neural substrate for neurodevelopmental impairment after premature delivery.

    Background and aim: Infantile colic is characterised by crying bouts in a healthy infant during the first months. Smoking in pregnancy and low birth weight (BW) have been previously identified as risk factors for infantile colic. Nicotine acts as a neurotransmitter and is known to affect...... the intrauterine central nervous system development, while low BW and premature birth have both been related to adverse neurodevelopmental outcomes. We investigated the association between intrauterine nicotine exposure, BW, gestational age (GA) and infantile colic in a large cohort study. Materials and methods......: We used data from the Danish National Birth Cohort. The study on nicotine exposure included 63,128 infants and the study on BW and GA included 62, 785 infants with complete data.

  13. Birth weight, breast cancer and the potential mediating hormonal environment.

    Directory of Open Access Journals (Sweden)

    Radek Bukowski

    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.

    2008-01-01

    In this analysis we connect structural neighborhood conditions to birth outcomes through their intermediate effects on mothers’ perceptions of neighborhood danger and their tendency to abuse substances during pregnancy. We hypothesize that neighborhood poverty and racial/ethnic concentration combine to produce environments that mothers perceive as unsafe, thereby increasing the likelihood of negative coping behaviors (substance abuse). We expect these behaviors, in turn, to produce ...

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

    Birth weight is an important determinant of infant's well being as low birth weight is known to increase the risk adult onset of diseases like type-2 diabetes and ischemic heart disease. Maternal weight gain is one of the most important independent predictors of infant birth weight. Institute of Medicine of the National Academics, USA has recommended that total weight gain of mothers should be according to their prepregnancy body mass index (BMI). Therefore, this study was conducted to observe the total weight gained by the pregnant women and the correlation between the weights gained by them with the birth weight of their infants. 98 women who delivered full term single baby at Patan hospital were included after taking their verbal consent. The details of the newborn and the history of the pregnant women were taken from the hospital records. The information about the family income, dietary habit, birth spacing and the type of work done by the pregnant women was obtained from the women themselves. The mean weight gain of the mothers was 9.48 (SD = 3.41) kilograms and the mean birth weight of the infants was found to be 2965.66 (SD = 364.37) grams. Multiple Liner Regression Models showed the effect of Gestational weight gain (GWG), Age and Parity on birth weight of the infant. Step-wise multiple regressions gave rise to models that showed effect of GWG and age on birth weight of the infants. This study concluded that gestational weight gain has positive linear relationship (correlation) with the birth weight of infants. PMID:21222408

    Full Text Available The aim of this study was to assess the association between prenatal exposure to air pollutants and low birth weight in a medium-sized city. An ecological study was performed, using live birth data from São José dos Campos, São Paulo State, Brazil. The environmental data were obtained from the São Paul State Environmental Agency. The study included full-term newborns whose mothers were 20 to 34 years of age and had at least a complete high school education, seven or more prenatal visits, singleton pregnancy, and vaginal delivery, in order to minimize potential confounding from these variables. Logistic regression was used to estimate the effect of each pollutant. Low birth weight was defined as less than 2,500g. The sample included a total of 2,529 data from 2001 that met the inclusion criteria (25.6% of the total. We identified 99 newborns (3.95% of the sample with low birth weight, and the pollutants sulfur dioxide and ozone were associated with low birth weight. The final model was À(x = -1.79 + 1.30 (SO2 + 1.26 (O3. Thus, sulfur dioxide and ozone were identified as risk factors for low birth weight in a medium-sized city in Southeast Brazil.

    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.

    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

    Brain development is a complex process of micro- and macrostructural events that include neuronal and glial proliferation and migration, myelination, and organizational development of cortical layers and circuitry. Recent progress in understanding these processes has provided insight into the pathophysiology of brain injury and alterations of cerebral development in preterm infants. A key factor of abnormalities in the preterm infant is the maturational stage of the brain at the time of birth. This review summarizes current data on normal brain development, patterns of brain injury in the preterm infant, and the associated axonal/neuronal disturbances that occur in the setting of this injury, often termed encephalopathy of prematurity.

    African-American infants weigh on average 200-300 grams less at birth than do European-American infants, leading to a two-fold higher rate of low birth-weight (LBW) infants. This birth weight disparity has not changed significantly over the past 95 years. Numerous research studies have been undertaken to elucidate this disparity. While various factors have been found to be associated with increased risk for having a LBW infant, including maternal anthropometrics, health and age, prenatal care, and socioeconomic status, none have been found to entirely and adequately explain the continued birth-weight differential. Researchers have concluded that there is something different in the environment and/or genetics of African-American women compared to European-American women, but are at a loss to clearly define the factor other than to say it must relate to the racism suffered by African-American women leading to more stress during pregnancy. While racism is probably an additional factor, one genetic/environmental variable, which has been overlooked, is the interaction of heavy pigmentation with degree of latitude. Heavy pigmentation blocks ultraviolet B (UVB) radiation. At high latitudes, such as in the US region, inadequate exposure to UVB radiation prevents the conversion of the prohormone to the hormonal form of vitamin D. The resulting low levels of serum vitamin D in the pregnant woman disrupt calcium homeostasis leading to intrauterine growth retardation, premature labor, and hypertension: all risk factors for LBW infants.

    This study examines the extent to which the relationship between area socioeconomic position (SEP) and low birth weight (LBW) varies by race and ethnicity. A cross-sectional, secondary data analysis was performed with 1992-1994 Vital Statistics and 1990 U.S. Census data for selected metropolitan areas. Low birth weight (poverty was defined as poor persons living in neighborhoods with 40% or more poverty in metropolitan areas. The results showed that the relationship between concentrated poverty and LBW varied by race and ethnicity. Concentrated poverty was significant for Latinos, even when controlling for maternal health and MSA-level factors. By contrast, maternal health characteristics, such as pre-term birth, teen birth and tobacco use, explained much of the variance in African-American and White LBW. These findings extend the discussion about race, class, and health disparities to include Latinos and shows how the relationship between SEP and LBW can vary within an ethnic group. PMID:18807774

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

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

    Throughout history, there has been the belief that diseases that affect the mouth, such as periodontal disease, can have an effect on the rest of the body. It is only very recently that scientists and clinicians have begun to provide an increasing body of scientific evidence suggesting that moderate untreated periodontitis may affect an individual systemically, and may contribute to cardiovascular disease, diabetes, and preterm low birth weight. Birth weight is affected by multiple factors and is considered as an outcome of a complex multifactorial system. Periodontitis is a remote gram-negative infection that may play a role in low birth weight. Periodontopathic microorganisms and their products have a wide range of effects mediated through host cytokine production in target cells. Many combined animal studies and data supporting plausible biologic mechanisms suggest that periodontal infection has a negative impact on pregnancy outcome in some women. PMID:24826203

    Data on body weight of pure-bred kittens (Maine Coon, Norwegian Forest Cat, Birman, Persian, Siamese/Oriental Shorthair Cat) from birth (n 245) to 12 weeks of age (n 135) were obtained from breeders. Absolute birth weight (in g) was higher in larger breeds than in smaller breeds, whereas relative birth weight (in % of mature female weight) tended to be higher in smaller breeds (Maine Coon 115 g, 2.3 %; Norwegian Forest Cat 106 g, 2.7 %; Birman 97 g, 2.8 %; Siamese 92 g, 2.8 %; Persian 82 g, 3.2 %). Relative birth weight was lower than that described in the literature for colony cats. Relative litter weight was highest in Norwegian Forest Cats (14.6 (SD 1.8) %; n 10) and lowest in Birmans (8.8 (SD 3.1) %, n 7; P cats but no clear-cut effect of breed size. There appeared to be a trend to an earlier onset of sexual dimorphism in larger breeds. PMID:22005433

    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 Weight at birth is usually considered as an indicator of the health status of a given society. As a result this study was designed to investigate the association between birth weight and maternal factors such as gestational weight gain, pre-pregnancy BMI and socio-economic status in Northern Ghana.The study was a facility-based cross-sectional survey conducted in two districts in the Northern region of Ghana. These districts were purposively sampled to represent a mix of urban, peri-urban and rural population. The current study included 419 mother-infant pairs who delivered at term (37-42 weeks. Mother's height, pre-pregnancy weight and weight changes were generated from the antenatal records. Questionnaires were administered to establish socio-economic and demographic information of respondents. Maternal factors associated with birth weight were examined using multiple and univariate regressions.The mothers were generally well nourished before conception (Underweight 3.82%, Normal 57.76%, Overweight 25.06% and Obesity 13.37% but approximately half of them could not gain adequate weight according to Institute of Medicine recommendations (Low weight gain 49.64%, Adequate weight gain 42.96% and Excessive weight gain 7.40%. Infants whose mothers had excess weight gain were 431g (95% CI 18-444 heavier compared to those whose mothers gained normal weight, while those whose mothers gained less were 479g (95% CI -682- (-276 lighter. Infants of mothers who were overweight and obese before conception were 246g (95% CI 87-405 and 595g (95% CI 375-815 respectively heavier than those of normal mothers, whereas those whose mothers were underweight were 305g (95% CI -565 -(-44 lighter. The mean birth weight observed was 2.98 ± 0.68 kg.Our findings show that pre-pregnancy body mass index and weight gain during pregnancy influence birth weight. Therefore, emphasis should be placed on counseling and assisting pregnant women to stay within the recommended weight

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

    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.

  8. Prediction of low birth weight infants from ultrasound measurement

    International Nuclear Information System (INIS)

    The aim of the study was to help to predict low birth weight infants by measuring placental diameter and thickness. A prospective study was conducted of 70 consecutive singleton pregnancies to evaluate placental diameter and thickness by ultrasonographic measurement at 36 weeks gestation. The individual data were fitted to a logistic regression analysis. A warning limit of a placental diameter of 18 cm and placental thickness of 2 cm at 36 weeks gestation were calculated to predict low birth weight infants. Ultrasonograhic placental diameter and thickness measurements appear to be of prognostic value in identifying the subsequent occurrence of fetal growth retardation. (author)

    Premature birth has been associated with damage in many regions of the cerebral cortex, although there is a particularly strong susceptibility for damage within the parieto-occipital lobes (Volpe, 2009). As these areas have been shown to be critical for both visual attention and magnitudes perception (time, space, and number), it is important to investigate the impact of prematurity on both the magnitude and attentional systems, particularly for children without overt white matter injuries, where the lack of obvious injury may cause their difficulties to remain unnoticed. In this study, we investigated the ability to judge time intervals (visual, audio and audio-visual temporal bisection), discriminate between numerical quantities (numerosity comparison), map numbers onto space (numberline task) and to maintain visuo-spatial attention (multiple-object-tracking) in school-age preterm children (N29). The results show that various parietal functions may be more or less robust to prematurity-related difficulties, with strong impairments found on time estimation and attentional task, while numerical discrimination or mapping tasks remained relatively unimpaired. Thus while our study generally supports the hypothesis of a dorsal stream vulnerability in children born preterm relative to other cortical locations, it further suggests that particular cognitive processes, as highlighted by performance on different tasks, are far more susceptible than others.

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

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

    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.

    2015-09-01

    A decade ago, the political party of the Italian center-right voted a law restricting immigration. The law became effective in early 2005, when the Italian parliament approved the decree for its application, but one of its articles, granting amnesty for illegal immigrant workers, became immediately effective in July 2002. As a result, 650,000 immigrants were granted the status of foreign nationals in Italy. In this paper, we examine whether the increase in the prevalence of "regular immigrants" has led to an improvement in health outcomes of babies born to migrant women, measured in terms of birth weight. Two hitherto unexploited birth sample surveys published by Italian Institute of Statistics were used for this study. Our estimates show that regularized immigration reduced the probability of low birth weight. PMID:26245767

    This study examines the association between maternal factors and low birth weight among newborns at a tertiary hospital in Malaysia. This was a cross-sectional study where mothers were followed through from first booking till delivery. There were 666 mothers who delivered from May 2007 to March 2008. Infants' birth weight were compared with maternal age, pre-pregnancy BMI, fathers BMI, parity, ethnicity, per capita monthly income, and maternal blood pressure during pregnancy. A multiple logistic regressions was used to determine the relationship of maternal factors and low birth weight, while the ROC curve was constructed to assess the sensitivity and specificity of the predictive model. Among the significant risk factors of low birth weight were older age (35 years and above), low pre-pregnancy BMI (blood pressure. Blood pressure during pregnancy was an important risk factor for LBW, by using this parameter alone the risk of LBW could be predicted with a sensitivity rate of 70% and a specificity rate of 70%. The sensitivity and specificity was further improved to 80% and 75% percent respectively when other factors like maternal factors such as maternal age, pre-pregnancy BMI, ethnicity, and per capita monthly income were included in the analysis.

    2012-01-01

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

    2014-12-01

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

    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.

    Full Text Available Aim &Background: Muslims fast from sunrise to sunset during Ramadan, the 9th lunar month. The duration of fasting varies from 13 to 18 hrs per day. Fasting individuals abstain from drinking liquids and eating foods. Manypregnant women and gynecologists are concerned about the possible complicationsassociated with fasting and effects on fetal health. The aim of this study was to determine the effect of Ramadan fasting on neonatalbirth weight.Materials and Methods: The current historical cohort study was performed on pregnant women attending maternity hospitals in Kashan in 2008. Twofasting and non-fasting groups were compared. Multiple pregnancies and gestational age less than 37 weeks were considered as the exclusion criteria. In fasting and non-fasting groups, age, parity, gestational age, body mass index (BMI, mother's occupation, prenatal care attendance and intended or unintended pregnancy were matched. For the statistical analysis of the data, covariance analysis and SPSS v16.0 were used. Results: In this study, 293 cases were evaluated among whom 31.7% did notfast. In the two groups, the mean age, gestational age, parity and weight gain during pregnancy were not significantly different. The mean birth weight was 3338 g (±498 g and 3343 g (± 339 g in fasting and non-fasting groups respectively. The results showed that the mean birth weight of the neonates in fasting and non-fasting groups was not significantly different (p=0. 931 Conclusion: The results of this study indicated that there is no significant relationship between the neonatal birth weight and maternal fasting during pregnancy. Therefore we declare thatfasting for pregnant women who receive prenatal care has no effects on neonatal birth weight.

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

  10. Birth weight: a major determinant of child survival.

    The problems of maternal malnutrition, low birthweight, and infant mortality and morbidity were investigated in a prospective study (1981-85) involving 7586 pregnant women (3197 from urban areas and 4389 from rural areas) in India. The mothers were followed until their infants were 1 year of age. There were 6879 live births among these women and 208 still births (a rate of 29.3/1000 deliveries). The perinatal, neonatal, and infant mortality rates were 65.3/1000, 57.7/1000, and 94.5/1000, respectively. 90% of these deaths involved infants with a birthweight below 2000 grams. Overall, 39% of infants studied were classified as low birthweight (under 2500 grams). Factors associated with low birthweight included maternal age below 19 years or over 35 years, maternal weight below 40 kg, maternal height below 145 cm, weight gain during pregnancy of under 5 kg, an interpregnancy interval less than 24 months, hemoglobin less than 8 grams%, and maternal illiteracy. Moderate to severe morbidity (neonatalas phyxia) was found in 10% of the births in this series. Breastfeeding was delayed beyond 24 hours in 77% of rural births and 13% of urban births; 30% of infants in both settings were given a bottle within the 1st week of life. 98% of rural mothers and 85% of urban mothers did not utilize available maternal-child health services in the postpartum period. Reducing the incidence of low birthweight births through primary health care interventions such as screening, food supplementation, adequate prenatal care, and correction of maternal nutritional deficiencies is the best strategy for improving infant survival in India. In the interim period, adequate health care must be made available to low birthweight infants and proper feeding practices should be promoted. PMID:3440594

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

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

    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.

    Data about aldosterone production and excretion in the neonatal period are still few and controversial. Our objectives are to assess urinary aldosterone excretion (UAE) in very low birth weight (VLBW) infants and to identify clinical and biochemical variables that may influence this excretion. Thirty VLBW infants (14 males and 16 females), their gestational age value was 0.176 ± 0.05 μg/24 h and the mean absolute UAE was 1906 ± 271 pg/mL. There was a statistically significant positive correlation between UAE and gestational age and birth weight; also, infants with respiratory distress syndrome had higher urinary aldosterone levels than infants without respiratory distress. Only plasma sodium was a significant independent factor that negatively influenced UAE on linear regression analysis. The renin-angiotensin-aldosterone system of VLBW infants seems to be able, even immediately after birth, to respond to variations of plasma sodium concentrations; measurement of UAE constitutes an interesting method to determine aldosterone production in VLBW infants.

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

    Directory of Open Access Journals (Sweden)

    Christopher W Kuzawa

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

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

    Full Text Available Abstract Background Advances in neonatal care allow survival of extremely premature infants, who are at risk of handicap. Neurodevelopmental follow up of these infants is an essential part of ongoing evaluation of neonatal care. The neonatal care in resource limited developing countries is very different to that in first world settings. Follow up data from developing countries is essential; it is not appropriate to extrapolate data from units in developed countries. This study provides follow up data on a population of very low birth weight (VLBW infants in Johannesburg, South Africa. Methods The study sample included all VLBW infants born between 01/06/2006 and 28/02/2007 and discharged from the neonatal unit at Charlotte Maxeke Johannesburg Academic Hospital (CMJAH. Bayley Scales of Infant and Toddler Development Version 111 (BSID 111 were done to assess development. Regression analysis was done to determine factors associated with poor outcome. Results 178 infants were discharged, 26 were not available for follow up, 9 of the remaining 152 (5.9% died before an assessment was done; 106 of the remaining 143 (74.1% had a BSID 111 assessment. These 106 patients form the study sample; mean birth weight and mean gestational age was 1182 grams (SD: 197.78 and 30.81 weeks (SD: 2.67 respectively. The BSID (111 was done at a median age of 16.48 months. The mean cognitive subscale was 88.6 (95% CI: 85.69 - 91.59, 9 (8.5% were Conclusion Although the neurodevelopmental outcome of this group of VLBW infants was within the normal range, with a low incidence of cerebral palsy, these results may reflect the low survival of babies with a birth weight below 900 grams. In addition, mean subscale scores were low and one third of the babies were identified as "at risk", indicating that this group of babies warrants long-term follow up into school going age.

    Objective To assess sleep practices, and investigate their relationship with maternal and fetal outcomes, among pregnant Ghanaian women. Methods In a cross-sectional study conducted at Korle Bu Teaching Hospital, Accra, Ghana, between June and July 2011, postpartum women were interviewed within 48 hours of delivery about sleep quality and practices during pregnancy. Interviews were coupled with a systematic review of participants’ medical charts for key outcomes including maternal hypertension, pre-eclampsia, premature delivery, low birth weight, and stillbirth. Results Most women reported poor sleep quality during pregnancy. Snoring during pregnancy was independently associated with pre-eclampsia (odds ratio [OR], 3.5; 95% confidence interval [CI], 1.4–8.5; P=0.007). The newborns of women who reported supine sleep during pregnancy were at increased risk of low birth weight (OR, 5.0; 95% CI, 1.2–20.2; P=0.025) and stillbirth (OR, 8.0; 95% CI, 1.5–43.2; P=0.016). Low birth weight was found to mediate the relationship between supine sleep and stillbirth. Conclusion The present findings in an African population demonstrate that maternal sleep, a modifiable risk factor, has a significant role in pre-eclampsia, low birth weight, and subsequently stillbirth.

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

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

    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

  16. Birth weight and weaning weight of Boer kids under an intensive management system

    International Nuclear Information System (INIS)

    In Malaysia, mutton (as chevon is called locally) is one of the main red meat consumed. The total mutton demand in 2007 was 20,000 mT. However, its output for the year was only 1750 mT, a mere 8.75% self-sufficiency. The demand is met by import of mutton and live animals, especially from Australia. However, with stimulus provided under the National Agricultural Policy and the recent introduction of the Boer goats with excellent body conformation, growth rate and carcass quality, the goat industry is rapidly developing. Many medium to large Boer goat farms are being established with purebred Boer goats and crosses imported from Australia and South African as breeding animals. Many of the farmers are new to the farming industry and have acquired knowledge and skills through short courses, publications, government extension workers, local and foreign stock suppliers, or hired consultants. To ensure the economic viability of the industry, good management systems, quality and cost-effective feed resources, and highly productive animals are essential. However, there is little information on the growth and reproductive performance of Boer goats in Malaysia. In addition, the effects of genetic and non-genetic factors influencing the traits of interest have yet to be evaluated. A project was undertaken to evaluate the growth performance of the Boer goats under intensive management system. This reports the preliminary results, focusing on the effects of year of birth, sex of kid and litter type on birth and weaning weights in one of the newly established Boer goat farms. The data is from 397 purebred Boer kids, offspring of 174 does and 16 bucks imported from Australia, in a medium sized (300-1000 heads), commercial farm. The kids were raised with their dams in group pens in raised, wooden sheds. They were fed fresh Napier grass, provided twice daily, supplemented with concentrated feed. The kids were weaned at about 90 d of age. The GLM procedure of SAS 9.1 was used to

    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

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

    Full Text Available Introduction: Nowadays, obesity is one of the most important health problems in both developed and developing countries. Recent studies have shown a significant association of obesity and its complications with birth weight. The aim of our study was to analyze the effect of birth weight on the occurrence of metabolic disorders in normal weight and obese women. Material and Methods: The study group included 134 females of average age 41.71±11.56 years. In these women the relationship between birth weight and anthropometric and biochemical parameters, as well as with blood pressure values was analyzed. Results: Our results show that women with higher birth weight had higher values of the anthropometric indicators of fat mass and distribution (such as body mass index, total fat mass, waist circumference and hip circumference, as well as higher values of high density lipoprotein-cholesterol. In contrast, the values of systolic and diastolic blood pressure and low density lipoprotein-cholesterol were lower in women with higher birth weight. The analysis of metabolic profile in women of different nutritional status indicates that normal weight women with metabolic syndrome had a lower birth weight when compared with normal weight women without metabolic risk (3.15 vs. 3.40 kg, p>0.05. Conclusion: Higher birth weight is related with higher fat mass, while lower birth weight is related with metabolic disturbances. Birth weight seemed to be determinant of metabolic risk in normal weight women.

    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.

    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.

    Necrotizing enterocolitis (NEC) is a devastating and common disease of very low birth weight (VLBW) infants with a mortality rate of 10% to 50% and a significant cause of morbidity in survivors. The incidence of NEC has increased from 5% to 7% in the last decades and this rate is likely to rise because of the increased survival of infants born at 24 weeks gestation, which are at high risk of developing NEC. NEC etiology is multifactorial: ischemia, infections, cytokines, enteral feeding and reactive oxygen species or free radicals (FRs) may contribute to the disruption of the immature gut barrier. In particular, ischemia, hypoxia-reperfusion, infection and inflammation are mechanisms capable of producing high levels of FRs, perturbing the normal redox balance and shifting cells to a state of oxidative stress (OS). Despite advances in neonatal medicine, the early diagnosis of NEC remains a major challenge. Early clinical signs are non specific and the laboratory findings are not fully reliable. Therefore, its delayed occurrence after birth, its rapid onset, the highly fulminant nature, and its severe morbidity, as well as the possibility of progression to death, strongly require the identification of new prospective biomarkers specific for high NEC risk. There is evidences that OS biomarkers in cord blood allow the early identification of infants at risk for NEC and thereby can be used to develop novel therapies for this devastating disease which predominantly occurs in premature infants.

    The aim of this study was to investigate associations of birth weight with sociodemographic variables, domestic violence, ways of coping, social support, and general mental health of Iranian mothers. Six hundred mothers aged 15 to 29 years participated between June 2009 and November 2010. t-Test, analysis of variance, Spearman's correlation, and multiple regression were used. The results showed that there was no significant association between birth weight and general mental health of the mothers. Prenatal care visits, the mothers' history of having children with low birth weight (LBW), and weight gain during pregnancy were significantly associated with birth weight. The women who reported physical abuse during pregnancy had infants with lower birth weight. Satisfaction with social support and use of positive reappraisal were significantly associated with higher birth weight. In conclusion, a high quality of prenatal care and screening of pregnant women are recommended. Social environments good enough during pregnancy have protective effects against LBW. PMID:23817159

    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 BACKGROUND AND OBJECTIVES: We present an updated birth weight-for-gestational-age portrait, based on nearly 8 million observations of an ethnic-mixed population. It comprises the first comprehensive charts with Brazilian data. This contribution intends to assist clinicians in classifying fetal growth, to provide a reference for investigations of predictors and to show the consequences of small and large patterns for gestational age delivery. Most of the reference data for assessing birth weight for gestational age deal with insufficient sample size, especially at low gestational age. Population-based studies with considerably large sample size refer to data collected more than 15 years ago. METHODS: We accomplished a population-based study on births in all the Brazilian states from 2003 to 2005. Results were based on 7,993,166 singletons. We constructed the 3rd, 5th, 10th, 25th, 50th, 90th, 95th and 97th smoothed percentiles curves and gender-specific tables from 22 to 43 completed weeks. RESULTS: The resulting tables and graphical representation provide a gender-specific reference to access the birth weights distribution according to the gestational age in the Brazilian population. CONCLUSIONS: This is the first population-based reference constructed on a developing country data. These charts could provide an important tool to improve clinical assessment of growth in newborns.BACKGROUND E OBJETIVOS: Apresentamos um retrato atualizado de peso-por-idade-gestacional, baseado em quase 8 milhões de observações em uma população etnicamente misturada.

    The present study examined whether exposure to vitamin D from fortified margarine and milk during prenatal life influenced mean birth weight and the risk of high or low birth weight. The study was based on the Danish vitamin D fortification programme, which was a societal intervention...... with mandatory fortification of margarine during 1961-1985 and voluntary fortification of low-fat milk between 1972 and 1976. The influence of prenatal vitamin D exposure on birth weight was investigated among 51 883 Danish children, by comparing birth weight among individuals born during 2 years before or after...... the initiation and termination of vitamin D fortification programmes.

    We conducted a retrospective study to determine the association between maternal body mass index and pregnancy weight gain with low birth weight newborns (LBWN) at Phrapokklao Hospital in eastern Thailand. We evaluated the files of 2,012 women who delivered at the hospital. Data obtained from the charts were parity, maternal age, body mass index (BMI), prepregnancy weight, weight gained during pregnancy, gestational age, hematocrit level, referral status, place of residence, fetal presentation, completion of antenatal care visits and maternal HIV infection. Sixty-five point two percent of subjects were aged 20-34 years old. Fifty-seven percent of subjects had a normal BMI and 13.2% were anemic. Thirty- seven point five percent, 32.9% and 29.6% gained too little, the correct amount and too much weight during pregnancy, respectively. Primiparity, too little weight gain and gestational age less than 37 weeks at delivery were all significantly associated with LBWN. Preterm babies were 25 times more likely to have a low birth weight than term infants (adjusted OR = 24.995; 95% CI: 16.824-37.133, p < 0.001). When maternal weight gain of any BMI group was inadequate, the subject had a 3.4 times greater risk (adjusted OR = 3.357; 95% CI: 22.114-5.332, p < 0.001) of having a LBWN. Primiparous women had a 1.7 times (adjusted OR=1.720; 95% CI: 1.182-2.503, p-0.005) greater risk of having a LBWN. The results from this study may be useful to plan maternal health programs for eastern Thailand. PMID:26867367

    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.

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

    2016-05-01

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

    In this paper we explore the impact of birth weight on children's cognitive and behavioural outcomes using data from the UK Millennium Cohort Study. In order to deal with the endogeneity of birth weight we use an estimator based on the eliminant method. When coupled with ordinary least squares, this estimator allows us to bound the effects of birth weight. The results show that birth weight has significant but very small effects on male cognitive development at age 3 and on female cognitive a...

    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.

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

    Full Text Available 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.

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

    2013-01-01

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

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

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

    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.

    Full Text Available OBJECTIVE: The Inuit population in Greenland has undergone rapid socioeconomic and nutritional changes simultaneously with an increasing prevalence of obesity. Therefore, the objective was to examine fetal programming as part of the aetiology of obesity among Inuit in Greenland by investigating the association between birth weight and measures of body composition and fat distribution in adulthood. METHODS: The study was based on cross-sectional data from a total of 1,473 adults aged 18-61 years in two population-based surveys conducted in Greenland between 1999-2001 and 2005-2010. Information on birth weight was collected from birth records. Adiposity was assessed by anthropometry, fat mass index (FMI, fat-free mass index (FFMI, and visceral (VAT and subcutaneous adipose tissue (SAT estimated by ultrasound. The associations to birth weight were analyzed using linear regression models and quadratic splines. Analyses were stratified by sex, and adjusted for age, birthplace, ancestry and family history of obesity. RESULTS: Spline analyses showed linear relations between birth weight and adult adiposity. In multiple regression analyses, birth weight was positively associated with BMI, waist circumference, FMI, FFMI and SAT with generally weaker associations among women compared to men. Birth weight was only associated with VAT after additional adjustment for waist circumference and appeared to be specific and inverse for men only. CONCLUSIONS: Higher birth weight among Inuit was associated with adiposity in adulthood. More studies are needed to explore a potential inverse association between birth size and VAT.

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

    Directory of Open Access Journals (Sweden)

    Steven M Yellon

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

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

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

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

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

  8. Determinants of Low Birth Weight in Malawi: Bayesian Geo-Additive Modelling.

    Directory of Open Access Journals (Sweden)

    Alfred Ngwira

    Full Text Available Studies on factors of low birth weight in Malawi have neglected the flexible approach of using smooth functions for some covariates in models. Such flexible approach reveals detailed relationship of covariates with the response. The study aimed at investigating risk factors of low birth weight in Malawi by assuming a flexible approach for continuous covariates and geographical random effect. A Bayesian geo-additive model for birth weight in kilograms and size of the child at birth (less than average or average and higher with district as a spatial effect using the 2010 Malawi demographic and health survey data was adopted. A Gaussian model for birth weight in kilograms and a binary logistic model for the binary outcome (size of child at birth were fitted. Continuous covariates were modelled by the penalized (p splines and spatial effects were smoothed by the two dimensional p-spline. The study found that child birth order, mother weight and height are significant predictors of birth weight. Secondary education for mother, birth order categories 2-3 and 4-5, wealth index of richer family and mother height were significant predictors of child size at birth. The area associated with low birth weight was Chitipa and areas with increased risk to less than average size at birth were Chitipa and Mchinji. The study found support for the flexible modelling of some covariates that clearly have nonlinear influences. Nevertheless there is no strong support for inclusion of geographical spatial analysis. The spatial patterns though point to the influence of omitted variables with some spatial structure or possibly epidemiological processes that account for this spatial structure and the maps generated could be used for targeting development efforts at a glance.

    The purpose of this review was to summarize existing epidemiological evidence of the association between quantitative estimates of indoor air pollution and all-day personal exposure with adverse birth outcomes including fetal growth, prematurity and miscarriage. We carried out a systematic literature search of MEDLINE and EMBASE databases with the aim of summarizing and evaluating the results of peer-reviewed epidemiological studies undertaken in "westernized" countries that have assessed indoor air pollution and all-day personal exposure with specific quantitative methods. This comprehensive literature search identified 16 independent studies which were deemed relevant for further review and two additional studies were added through searching the reference lists of all included studies. Two reviewers independently and critically appraised all eligible articles using the Critical Appraisal Skills Programme (CASP) tool. Of the 18 selected studies, 14 adopted a prospective cohort design, three were case-controls and one was a retrospective cohort study. In terms of pollutants of interest, seven studies assessed exposure to electro-magnetic fields, four studies assessed exposure to polycyclic aromatic hydrocarbons, four studies assessed PM2.5 exposure and three studies assessed benzene, phthalates and noise exposure respectively. Furthermore, 12 studies examined infant growth as the main birth outcome of interest, six examined spontaneous abortion and three studies assessed gestational age at birth and preterm delivery. This survey demonstrates that there is insufficient research on the possible association of indoor exposure and early life effects and that further research is needed. PMID:24896737

    Extremely low birth weight (ELBW) infants frequently require endotracheal intubation for assisted ventilation or as a route for administration of drugs or exogenous surfactant. In adults and less premature infants, the risks of this intubation can be greatly reduced using video laryngoscopy, but current products are too large and incorrectly shaped to visualize an ELBW infant's airway anatomy. We design and prototype a video laryngoscope using a miniature camera set in a curved acrylic blade with a 3×6-mm cross section at the tip. The blade provides a mechanical structure for stabilizing the tongue and acts as a light guide for an LED light source, located remotely to avoid excessive local heating at the tip. The prototype is tested on an infant manikin and found to provide sufficient image quality and mechanical properties to facilitate intubation. Finally, we show a design for a neonate laryngoscope incorporating a wafer-level microcamera that further reduces the tip cross section and offers the potential for low cost manufacture.

    2016-03-01

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

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

  13. KIR and HLA-C: Immunogenetic regulation of human birth weight

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

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

    Full Text Available BACKGROUND: Low birth weight (LBW remains to be a leading cause of neonatal death and a major contributor to infant and under-five mortality. Its prevalence has not declined in the last decade in sub-Saharan Africa (SSA and Asia. Some individual level factors have been identified as risk factors for LBW but knowledge is limited on contextual risk factors for LBW especially in SSA. METHODS: Contextual risk factors for LBW in Ghana were identified by performing multivariable multilevel logistic regression analysis of 6,900 mothers dwelling in 412 communities that participated in the 2003 and 2008 Demographic and Health Surveys in Ghana. RESULTS: Contextual-level factors were significantly associated with LBW: Being a rural dweller increased the likelihood of having a LBW infant by 43% (OR 1.43; 95% CI 1.01-2.01; P-value <0.05 while living in poverty-concentrated communities increased the risk of having a LBW infant twofold (OR 2.16; 95% CI 1.29-3.61; P-value <0.01. In neighbourhoods with a high coverage of safe water supply the odds of having a LBW infant reduced by 28% (OR 0.74; 95% CI 0.57-0.96; P-value <0.05. CONCLUSION: This study showed contextual risk factors to have independent effects on the prevalence of LBW infants. Being a rural dweller, living in a community with a high concentration of poverty and a low coverage of safe water supply were found to increase the prevalence of LBW infants. Implementing appropriate community-based intervention programmes will likely reduce the occurrence of LBW infants.

    Full Text Available Abstract Background The aim of this study was to validate a model for optimal birth weight derived from neonatal records, and to test the assumption that preterm births may be considered optimally grown if they are not exposed to common factors that perturb fetal growth. Methods Weights of fetuses were estimated from serial biometric ultrasound scans (N = 2,848 and combined with neonatal weights for a prospective pregnancy cohort (N = 691. Non-Caucasians, fetuses subsequently born preterm and those with diagnosed or suspected determinants of aberrant growth were excluded leaving fetuses assumed to have experienced normal growth. A generalised linear longitudinal growth model for optimal weight was derived, including terms for gestational duration, infant sex, maternal height and birth order. This model was compared to a published model derived solely from birth weights. Results Prior to 30 weeks gestation, the published model yielded systematically lower weights than the model derived from both fetal weight and neonatal weight. From 30 weeks gestation the two models were indistinguishable. Conclusion The model for optimal birth weight was valid for births that have attained at least 30 weeks gestation. The model derived from both fetal and neonatal weights is recommended prior to this gestation.

    The goal of this study was to evaluate the relation between kittens' birth weights and biometrical factors from the kittens and the mother during pregnancy. Knowing fetal birth weight could help in detecting abnormalities before parturition. A Caesarean-section or a postnatal management plan could be scheduled. Consequently, the neonatal mortality rate should be decreased. We used ultrasonographic measurements of femur length (FL) or fetal biparietal diameter (BPD), pregnancies, and maternal factors to obtain a model of prediction. For this purpose, linear mixed-effects models were used because of random effects (several fetuses for one queen and a few paired measurements) and fixed effects (litter size, pregnancy rank, weight, wither height, and age of the queen). This study was performed in 24 purebred queens with normal pregnancies and normal body conditions. Queens were scanned in the second half of pregnancy, using a micro-convex probe. They gave birth to 140 healthy kittens whose mean birth weight was 104 g (ranged 65 to 165 g). No correlation between the birth weight and the age of the queen, as a maternal factor alone, was observed. But the birth weight was found to be inversely proportional to the pregnancy rank and the litter size. Moreover, birth weight increased when the weight and wither height of queen increased. BPD and FL increased linearly during pregnancy so a model was used to estimate mean birth weight. Using this model, we found a correlation between mean birth weights and an association of parameters: maternal factors (wither height and age), and litter size. PMID:21820718

    Birth weight is an important indicator of overall infant health and a strong predictor of infant morbidity and mortality, and low birth weight (LBW) is a leading cause of infant mortality in the United States. Numerous studies have examined the associations of birth weight with ambient air pollution, but the results were inconsistent. In this study, a spatial statistical technique, geographically weighted regression (GWR) is applied to explore the spatial variations in the associations of birth weight with concentrations of ozone (O3) and fine particulate matter (PM2.5) in the State of Georgia, USA adjusted for gestational age, parity, and six other socioeconomic, behavioral, and land use factors. The results show considerable spatial variations in the associations of birth weight with both pollutants. Significant positive, non-significant, and significant negative relationships between birth weight and concentrations of each air pollutant are all found in different parts of the study area, and the different types of the relationships are affected by the socioeconomic and urban characteristics of the communities where the births are located. The significant negative relationships between birth weight and O3 indicate that O3 is a significant risk factor of LBW and these associations are primarily located in less-urbanized communities. On the other hand, PM2.5 is a significant risk factor of LBW in the more-urbanized communities with higher family income and education attainment. These findings suggest that environmental and health policies should be adjusted to address the different effects of air pollutants on birth outcomes across different types of communities to more effectively and efficiently improve birth outcomes.

    Full Text Available OBJECTIVE: Lower birth weight is associated with higher insulin resistance in later life. The aim of this study was to determine whether cardiorespiratory fitness modifies the association of birth weight with insulin resistance in adults. METHODS: The subjects were 379 Japanese individuals (137 males, 242 females aged 20-64 years born after 1943. Insulin resistance was assessed using a homeostasis model assessment of insulin resistance (HOMA-IR, which is calculated from fasting blood glucose and insulin levels. Cardiorespiratory fitness (maximal oxygen uptake, VO2max was assessed by a maximal graded exercise test on a cycle ergometer. Birth weight was reported according to the Maternal and Child Health Handbook records or the subject's or his/her mother's memory. RESULTS: The multiple linear regression analysis revealed that birth weight was inversely associated with HOMA-IR (β = -0.141, p = 0.003, even after adjustment for gender, age, current body mass index, mean blood pressure, triglycerides, HDL cholesterol, and smoking status. Further adjustments for VO2max made little difference in the relationship between birth weight and HOMA-IR (β = -0.148, p = 0.001, although VO2max (β = -0.376, p<0.001 was a stronger predictor of HOMA-IR than birth weight. CONCLUSIONS: The results showed that the association of lower birth weight with higher insulin resistance was little modified by cardiorespiratory fitness in adult life. However, cardiorespiratory fitness was found to be a stronger predictor of insulin resistance than was birth weight, suggesting that increasing cardiorespiratory fitness may have a much more important role in preventing insulin resistance than an individual's low birth weight.

    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.

    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 Abstract Background Meconium abnormalities are characterized by a wide spectrum of severity, from the meconium plug syndrome to the complicated meconium ileus associated with cystic fibrosis. Meconium Related Ileus in absence of Cystic Fibrosis includes a combination of highly viscid meconium and poor intestinal motility, low grade obstruction, benign systemic and abdominal examination, distended loops without air fluid levels. Associated risk factors are severe prematurity and low birth weight, Caesarean delivery, Maternal MgSO4 therapy, maternal diabetes. In the last 20 yrs a new specific type of these meconium related obstructions has been described in premature neonates with low birth weight. Its incidence has shown to increase while its management continues to be challenging and controversial for the risk of complicated obstruction and perforation. Materials and methods Among 55 newborns admitted between 1992-2008 with Meconium Related Ileus as final diagnosis, data about Low Birth Weight infants (LBW Results 30 cases with BW ≥ 1500 g had an M/F ratio16/14, Mean B.W. 3052 g, Mean G.A. 37 w Caesarean section rate 40%.

    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

    This study examined racial/ethnic differences in gestational weight gain (GWG) predictors and association of first-trimester GWG to overall GWG among 271 White women and 300 Latina women. Rates of within-guideline GWG were higher among Latinas than among Whites (28.7% versus 24.4%, p < 0.016). Adjusted odds of above-guideline GWG were higher among prepregnancy overweight (OR = 3.4, CI = 1.8–6.5) and obese (OR = 4.5, CI = 2.3–9.0) women than among healthy weight women and among women with above-guideline first-trimester GWG than among those with within-guideline first-trimester GWG (OR = 4.9, CI = 2.8–8.8). GWG was positively associated with neonate birth size (p < 0.001). Interventions targeting prepregnancy overweight or obese women and those with excessive first-trimester GWG are needed.

    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

    Low birth weight (LBW) can have an impact on health outcomes in later life, especially in relation to pre-disposition to metabolic disease. Several studies suggest that LBW resulting from restricted intrauterine growth leaves a footprint on DNA methylation in utero, and this influence likely...... persists into adulthood. To investigate this further, we performed epigenome-wide association analyses of blood DNA methylation using Infinium HumanMethylation450 BeadChip profiles in 71 adult monozygotic (MZ) twin pairs who were extremely discordant for birth weight.

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

  7. Associations of meteorology with adverse pregnancy outcomes: a systematic review of preeclampsia, preterm birth and birth weight.

    The relationships between meteorology and pregnancy outcomes are not well known. This article reviews available evidence on the relationships between seasonality or meteorology and three major pregnancy outcomes: the hypertensive disorders of pregnancy (including preeclampsia, eclampsia and gestational hypertension), gestational length and birth weight. In total 35, 28 and 27 studies were identified for each of these outcomes. The risks of preeclampsia appear higher for women with conception during the warmest months, and delivery in the coldest months of the year. Delivery in the coldest months is also associated with a higher eclampsia risk. Patterns of decreased gestational lengths have been observed for births in winter, as well as summer months. Most analytical studies also report decreases in gestational lengths associated with heat. Birth weights are lower for deliveries occurring in winter and in summer months. Only a limited number of studies have investigated the effects of barometric pressure on gestational length or the effects of temperature and sunshine exposure on birth weight, but these questions appear worth investigating further. Available results should encourage further etiological research aiming at enhancing our understanding of the relationships between meteorology and adverse pregnancy outcomes, ideally via harmonized multicentric studies.

    Many factors contribute to variation in lamb weights. Factors such as age of lamb, sex, type of birth and rearing, and ewe age at lambing obscure genetic differences among lambs. Variation associated with these factors make selection for increased weight less effective. To improve selection response, selection must be based on genotypic rather than environmentally induced superiority. It is well-documented that corrections for classifiable sources of variation render selection and culling mor...

    . Most previous studies and trials were not sufficiently large and did not include long-term patient oriented outcomes. Multicenter, randomized, outcome trials are needed to determine whether NAVA is effective in avoiding intubation, facilitating extubation, decreasing time of ventilation, reducing the incidence of CLD, decreasing length of stay, and improving long-term outcomes such as the duration of ventilation, length of hospital stay, rate of pneumothorax, CLD and other major complications of prematurity. In order to prevent barotrauma, next generations of NAVA equipment for neonatal use should enable automatic setting of ventilator parameters in the backup PC mode based on the values generated by NAVA. They should also include an upper limit to the inspiratory time as in conventional ventilation. The manufacturers of Edi catheters should produce smaller sizes available for extreme low birth weight infants. Newly developed ventilators should also include leak compensation and high frequency ventilation. A peripheral flow sensor is also essential to the proper delivery of all modes of conventional ventilation as well as NAVA. PMID:26140273

    The aim of this study was to determine if syndrome-specific birth weight charts were beneficial for babies with Down syndrome in England and Wales. Birth weights of 8,825 babies with Down syndrome born in England and Wales in 1989-2010 were obtained from the National Down Syndrome Cytogenetic Register. Birth weight centiles for 30-42 weeks gestation by sex were fitted using the LMS method and were compared to those for unaffected babies from the UK-WHO growth charts. For babies born with Down syndrome the median birth weight from 37 to 42 weeks was 2,970 g (10th-90th centile: 2,115-3,680) for boys and 2930 g (2,100-3,629) for girls, and the modal age of gestation was 38 weeks, 2 weeks earlier than for unaffected babies. At 38 weeks gestation they were only slightly lighter than unaffected babies (159 g for boys and 86 g for girls). However at 40 weeks gestation the shortfall was much greater (304 g and 239 g, respectively). In neonates with Down syndrome there is little evidence of growth restriction before 38 weeks gestation, so up to this age it is appropriate to use the UK-WHO birth weight charts. Thereafter birth weight is below that of unaffected babies and it should be plotted on the UK Down syndrome growth charts.

    Full Text Available Background: weight of the baby at birth is considered to be a major determinant of future health and survival of the child. It is one of the important factors which determine the readiness with which the newborn baby adjusts to its surrounding. Many maternal socio-biological factors influence birth weight. Objective: To determine maternal socio-biological factors influencing birth weight of newborn. Methodology: Hospital based cross- sectional study undertaken in Obstetrics and Gynaecology ward of Nehru hospital, Gorakhpur. The study period extended from July 2011 to August 2012. The study subject included recently delivered mothers and data was collected on semi-structured interview schedule to know various socio-biological variables such as mother’s age, parity, inter-pregnancy interval etc, influencing the low birth weight of newborn. Chi-Square test was applied to observe the significance of association.  Results: The overall proportion of low birth weight baby came out to be 32.06%. Out of various socio-biological factors taken the factors which came out to be statistically significant were age of mother, parity, inter-pregnancy interval, SLI, education. The factors which were not statistically significant were father’s education, religion. Conclusions:  It was concluded that teenage pregnancy, non-utilization of antenatal care practices, anaemia, illiteracy are unfavorable predictors of birth weight of newborn babies.

  14. Neonatal doses from X ray examinations by birth weight in a neonatal intensive care unit

    International Nuclear Information System (INIS)

    The aim of this study was to investigate the frequency and type of X ray examinations performed on neonates classified according to their birth weight in a neonatal intensive care unit (NICU). In this study, the radiology records of 2408 neonates who were admitted to the NICU of Oita Prefectural Hospital between January 1994 and September 1999 were investigated. This study revealed that the neonates with earlier gestational ages and lower birth weights required longer NICU stays and more frequent X ray examinations made using a mobile X ray unit. The average number of X ray examinations performed on neonates of less than 750 g birth weight was 26 films per neonate. In regard to computed tomography and fluoroscopy, no significant relationship was found between the birth weight and number of X rays. This study revealed that the entrance-surface dose per neonate was dependent upon the birth weight, while the maximum dose was not dependent upon the birth weight. The average neonatal dose in the NICU was predominantly from computed tomography and fluoroscopy. The individual dose varied widely among neonates. (author)

    Full Text Available There have been several epidemiologic studies on the relationship between high birth weight and the risk for bone tumor in the past decades. However, due to the rarity of bone tumors, the sample size of individual studies was generally too small for reliable conclusions. Therefore, we have performed a meta-analysis to pool all published data on electronic databases with the purpose to clarify the potential relationship. According to the inclusion and exclusion criteria, 18 independent studies with more than 2796 cases were included. As a result, high birth weight was found to increase the risk for bone tumor with an Odds Ratio (OR of 1.13, with the 95% confidence interval (95% CI ranging from 1.01 to 1.27. The OR of bone tumor for an increase of 500 gram of birth weight was 1.01 (95% CI 1.00–1.02; p = 0.048 for linear trend. Interestingly, individuals with high birth weight had a greater risk for osteosarcoma (OR = 1.22, 95% CI 1.06–1.40, p = 0.006 than those with normal birth weight. In addition, in the subgroup analysis by geographical region, elevated risk was detected among Europeans (OR = 1.14, 95% CI 1.00–1.29, p = 0.049. The present meta-analysis supported a positive association between high birth weight and bone tumor risk.

  18. Recombinant human erythropoietin and blood transfusion in low-birth weight preterm infants under restrictive transfusion guidelines

    International Nuclear Information System (INIS)

    To compare the number and volume of red blood cell transfusions (RBCTs) in very low birth weight infants under restrictive red blood cell transfusion guidelines with and without erythropoietin administration. In a controlled clinical trial conducted at the neonatal intensive care unit of Alzahra Hospital, Isfahan, Iran, between April 2002 to April 2004, 60 premature infants with gestational age up to 34 weeks, birth weight up to 1500 g, and postnatal age between 8 and 14 days were included. The newborns were randomized into 2 groups: Group 1 received 3 doses of 400 IU/kg erythropoietin per week for 6 weeks, and Group 2 received no treatment aside from their conventional medications. The 2 groups did not differ significantly with respect to their mean gestational age, birth weight and hematocrit at the study entry. Fewer transfusions were administered to those receiving erythropoietin (26.7% versus 50%, p=0.03), but there was no statistically significant difference between groups with respect to volume of transfusion. Compared with the placebo group, the infants receiving erythropoietin had a higher mean hematocrit (34% +/- 4.3 versus 29% +/- 5.9, p<0.001) and absolute reticulocyte count (57 +/- 19 versus 10 +/- 4.8 x 106, p<0.001) at the end of the study. We found no significant difference in the incidence of thrombocytopenia and leukopenia between the 2 groups. We conclude that when the restrictive RBCT guidelines were followed, treatment with erythropoietin can be useful in reduction of the number of RBCTs. (author)

    Full Text Available BACKGROUND: Low birth weight and prematurity are amongst the strongest predictors of neonatal death. However, the extent to which they act independently is poorly understood. Our objective was to estimate the neonatal mortality risk associated with preterm birth when stratified by weight for gestational age in the high mortality setting of East Africa. METHODS AND FINDINGS: Members and collaborators of the Malaria and the MARCH Centers, at the London School of Hygiene & Tropical Medicine, were contacted and protocols reviewed for East African studies that measured (1 birth weight, (2 gestational age at birth using antenatal ultrasound or neonatal assessment, and (3 neonatal mortality. Ten datasets were identified and four met the inclusion criteria. The four datasets (from Uganda, Kenya, and two from Tanzania contained 5,727 births recorded between 1999-2010. 4,843 births had complete outcome data and were included in an individual participant level meta-analysis. 99% of 445 low birth weight (< 2,500 g babies were either preterm (< 37 weeks gestation or small for gestational age (below tenth percentile of weight for gestational age. 52% of 87 neonatal deaths occurred in preterm or small for gestational age babies. Babies born < 34 weeks gestation had the highest odds of death compared to term babies (odds ratio [OR] 58.7 [95% CI 28.4-121.4], with little difference when stratified by weight for gestational age. Babies born 34-36 weeks gestation with appropriate weight for gestational age had just three times the likelihood of neonatal death compared to babies born term, (OR 3.2 [95% CI 1.0-10.7], but the likelihood for babies born 34-36 weeks who were also small for gestational age was 20 times higher (OR 19.8 [95% CI 8.3-47.4]. Only 1% of babies were born moderately premature and small for gestational age, but this group suffered 8% of deaths. Individual level data on newborns are scarce in East Africa; potential biases arising due to the non

CONCLUSIONS: Low birth weight is a risk factor for asthma independently of gestational age, sex, birth...... length and Apgar score, but this may be due, in part, to residual non-genetic confounding factors.

  1. Birth weight, intrauterine growth retardation and fetal susceptibility to porcine reproductive and respiratory syndrome virus.

    Directory of Open Access Journals (Sweden)

    Andrea Ladinig

    Full Text Available The severity of porcine reproductive and respiratory syndrome was compared in pregnant gilts originating from high and low birth weight litters. One-hundred and eleven pregnant gilts experimentally infected with porcine reproductive and respiratory syndrome virus on gestation day 85 (±1 were necropsied along with their fetuses 21 days later. Ovulation rates and litter size did not differ between groups, but fetuses from low birth weight gilts were shorter, lighter and demonstrated evidence of asymmetric growth with large brain:organ weight ratios (i.e. brain sparing. The number of intrauterine growth retarded fetuses, defined by brain:organ weight ratios greater than 1 standard deviation from the mean, was significantly greater in low, compared to high, birth weight gilts. Although γδ T cells significantly decreased over time in high compared to low birth weight gilts, viral load in serum and tissues, gilt serum cytokine levels, and litter outcome, including the percent dead fetuses per litter, did not differ by birth weight group. Thus, this study provided no substantive evidence that the severity of porcine reproductive and respiratory syndrome is affected by dam birth weight. However, intrauterine growth retarded fetuses had lower viral loads in both fetal thymus and in endometrium adjacent to the umbilical stump. Crown rump length did not significantly differ between fetuses that survived and those that died at least one week prior to termination. Taken together, this study clearly demonstrates that birth weight is a transgenerational trait in pigs, and provides evidence that larger fetuses are more susceptible to transplacental PRRSv infection.

    Structured abstract Importance Neonates born to overweight/obese women are larger and at higher risk of birth complications. Many maternal obesity-related traits are observationally associated with birth weight, but the causal nature of these associations is uncertain. Objective To test for genetic evidence of causal associations of maternal body mass index (BMI) and related traits with birth weight. Design, Setting and Participants We used Mendelian randomization to test whether maternal BMI and obesity-related traits are causally related to offspring birth weight. Mendelian randomization makes use of the fact that genotypes are randomly determined at conception and are thus not confounded by non-genetic factors. Data were analysed on 30,487 women from 18 studies. Participants were of European ancestry from population- or community-based studies located in Europe, North America or Australia and participating in the Early Growth Genetics (EGG) Consortium. Live, term, singleton offspring born between 1929 and 2013 were included. We tested associations between a genetic score of 30 BMI-associated single nucleotide polymorphisms (SNPs) and (i) maternal BMI and (ii) birth weight, to estimate the causal relationship between BMI and birth weight. Analyses were repeated for other obesity-related traits. Exposures Genetic scores for BMI, fasting glucose level, type 2 diabetes, systolic blood pressure (SBP), triglyceride level, HDL-cholesterol level, vitamin D status and adiponectin level. Main Outcome(s) and Measure(s) Offspring birth weight measured by trained study personnel (n=2 studies), from medical records (n= 10 studies) or from maternal report (n=6 studies). Results Among the 30,487 newborns the mean birth weight in the various cohorts ranged from 3325 g to 3679 g. The genetic score for BMI was associated with a 2g (95%CI: 0, 3g) higher offspring birth weight per maternal BMI-raising allele (P=0.008). The maternal genetic scores for fasting glucose and SBP were

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

    The "fetal origins" hypothesis suggests that fetal conditions not only affect birth characteristics such as birth weight and gestational age, but also have lifelong health implications. Despite widespread interest in this hypothesis, few methodological advances have been proposed to improve the measurement and modeling of fetal conditions. A Statistics in Medicine paper by Bollen, Noble, and Adair examined favorable fetal growth conditions (FFGC) as a latent variable. Their study of Filipino children from Cebu provided evidence consistent with treating FFGC as a latent variable that largely mediates the effects of mother's characteristics on birth weight, birth length, and gestational age. This innovative method may have widespread utility, but only if the model applies equally well across diverse settings. Our study assesses whether the FFGC model of Cebu replicates and generalizes to a very different population of children from North Carolina (N=705) and Pennsylvania (N=494). Using a series of structural equation models, we find that key features of the Cebu analysis replicate and generalize while we also highlight differences between these studies. Our results support treating fetal conditions as a latent variable when researchers test the fetal origins hypothesis. In addition to contributing to the substantive literature on measuring fetal conditions, we also discuss the meaning and challenges involved in replicating prior research. PMID:27097023

    The extremes of birth weight and preterm birth are known to result in a host of adverse outcomes, yet studies to date largely have used cross-sectional designs and variable-centered methods to understand long-term sequelae. Growth mixture modeling (GMM) that utilizes an integrated person- and variable-centered approach was applied to identify latent classes of achievement from a cohort of school-age children born at varying birth weights. GMM analyses revealed 2 latent achievement classes for calculation, problem-solving, and decoding abilities. The classes differed substantively and persistently in proficiency and in growth trajectories. Birth weight was a robust predictor of class membership for the 2 mathematics achievement outcomes and a marginal predictor of class membership for decoding. Neither visuospatial-motor skills nor environmental risk at study entry added to class prediction for any of the achievement skills. Among children born preterm, neonatal medical variables predicted class membership uniquely beyond birth weight. More generally, GMM is useful in revealing coherence in the developmental patterns of academic achievement in children of varying weight at birth and is well suited to investigations of sources of heterogeneity.

    Full Text Available Background: Chest radiography has been the traditional method of diagnostic evaluation of patients of hyaline membrane disease (HMD. Lung sonography (USG has been lately explored as an alternative modality. Aims: To explore the application of transabdominal USG of lung bases (TASL in the evaluation of HMD in premature neonates with respiratory distress soon after birth. Settings and Design: Tertiary care institutional setup. Study duration-18 months. Follow-up-variable, up to 1 month. Prospective descriptive study. Materials and Methods: Eighty-eight consecutive patients admitted in the neonatal intensive care unit (NICU with gestational age <32 weeks having respiratory distress within 6 h of birth were enrolled. The diagnosis of HMD was made if the patient had negative gastric shake test and/or suggestive chest radiograph. TASL was performed in all patients within the first 24 h of life and biweekly subsequently. USG was interpreted as normal, HMD pattern, or broncho-pulmonary dysplasia (BPD pattern. Biweekly follow-up was done for patients showing HMD till normalization of the sonographic HMD pattern, development of the sonographic BPD pattern, or death/discharge of the neonate from the hospital. Results and Conclusions: TASL showed 85.7% sensitivity, 75% specificity, 88.88% positive predictive value, and 69.2% negative predictive value for the diagnosis of HMD. The abnormal sonographic findings on day 14 had 94.1% accuracy for prediction of eventual occurrence of clinical BPD. TASL is complementary to chest radiograph in the diagnosis of HMD. It is also useful for the early prediction of BPD with the potential of reducing the cumulative radiation dose to these neonates.

    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.

    Very low birth weight is associated with long term neurodevelopmental complications. Macroscopic brain abnormalities in prematurity survivors have been investigated in several studies. However, there is limited data regarding local cerebral metabolic status and neurodevelopmental outcomes. The purpose of this study was to characterize the relationship between proton magnetic resonance spectra in basal ganglia, frontal white matter and frontoinsular gray matter, neurodevelopmental outcomes assessed with the Leiter scale and the Developmental Test of Visual Perception and selected socioeconomic variables in a cohort of very low birth weight children at the age of four. Children were divided in three groups based on the severity of neurodevelopmental impairment. There were no differences in spectroscopy in basal ganglia and frontal white matter between the groups. Lower concentrations of N-acetylaspartate (NAA), choline (Cho) and myoinositol (mI) were observed in the frontoinsular cortex of the left hemisphere in children with neurodevelopmental impairment compared to children with normal neurodevelopmental outcomes. Higher parental education, daycare attendance and breastfeeding after birth were associated with more favorable neurodevelopmental prognosis, whereas rural residence was more prevalent in children with moderate and severe impairment. Our study demonstrates the role of long term neurometabolic disruption in the left frontoinsular cortex and selected socioeconomic variables in determination of neurodevelopmental prognosis in prematurity survivors.

Lower concentrations of N-acetylaspartate (NAA, choline (Cho and myoinositol (mI were observed in the frontoinsular cortex of the left hemisphere in children with neurodevelopmental impairment compared to children with normal neurodevelopmental outcomes. Higher parental education, daycare attendance and breastfeeding after birth were associated with more favorable neurodevelopmental prognosis, whereas rural residence was more prevalent in children with moderate and severe impairment. Our study demonstrates the role of long term neurometabolic disruption in the left frontoinsular cortex and selected socioeconomic variables in determination of neurodevelopmental prognosis in prematurity survivors.

    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 Background: nowadays, hypertension is a health problem directly causing disability and death. Epidemiological data suggest that pre- and postnatal nutrition can be an important factor in the etiopathogenesis of this disease. Objective: to evaluate the effects of low birth weight on blood pressure and kidney size in adolescent females. Methods: a cross-sectional study was conducted in 50 adolescent females from Marianao, Havana. The following variables were measured: weight, height, systolic and diastolic blood pressure, birth weight and length and body mass index. Kidney length, width, parenchyma and volume were measured by ultrasound. Results: differences in blood pressure related to weight and length at birth were nonsignificant. Renal variables did not show significant changes in the classification by birth weight. An important relationship between systolic blood pressure and two indicators of the relative kidney size was found. Conclusion: results did not show an association between low birth weight and high blood pressure. It is demonstrated that blood pressure values are positively related to body adiposity and small kidney size.

    Full Text Available Abstract Background Research has highlighted a series of persistent deficits in cognitive ability in preterm low-birth-weight children. Language and attention problems are among these deficits, although the nature of the relation between attention and language in early development is not well known. This study represents a preliminary attempt to shed light on the relations between attention problems and language development in preterm low-birth-weight children. Methods The aim of this study was to analyse reciprocal influences between language and attention problems from 18 to 36 months. We used maternal reports on attention problems and language ability referring to a sample of 1288 premature low-birth-weight infants, collected as part of the Norwegian Mother and Child Cohort Study (MoBa. A sample of children born full-term was used as the control group (N = 37010. Cross-lagged panel analyses were carried out to study reciprocal influences between attention problems and language. Results Language ability at 18 months did not significantly predict attention problems at 36 months, adjusting for attention problems at 18 months. Attention problems at 18 months significantly predicted changes in language ability from 18 to 36 months, pointing to a precursor role of attention in relation to language in children born preterm. Gender, age corrected for prematurity, and mother's education emerged as important covariates. Conclusions Preliminary evidence was found for a precursor role of early attention problems in relation to language in prematurity. This finding can contribute to a better understanding of the developmental pathways of attention and language and lead to better management of unfavourable outcomes associated with co-morbid attention and language difficulties.

  17. Brain CT scans and clinical study in very-low-birth-weight infants, including eight cases of cerebellar porencephaly

    International Nuclear Information System (INIS)

    Fifty-nine brain CT scans taken in very-low-birth-weight infants ( < 1500 g) during the past three years were studied retrospectively. Eighty-nine cases of very-low-birth-weight infants were admitted to our premature nursery during the period from Jan. 1, 1982 to Dec. 31, 1984. We obtained brain CT scans in 59 of them, and studied them retrospectively. a) Normal CT in 25 cases, b) enlargement of the extracerebral space in 17, c) megacisterna magna in four, d) unilateral ventriculomegaly in six, e) hydrocephalus in seven, f) cerebral porencephaly in two, g) brain stem atrophy in seven, and h) low density area in the posterior fossa in eight, were observed. The clinical courses of patients a) to f) above were almost similar to those previously reported. g) brain stem atrophy was found on CT scans in seven cases. Five of them developed infantile spasms later. This suggests that one of the main sites of lesions in infantile spasms is the tegmentum of the brain stem. h) Low density area in the posterior fossa was found on CT in eight cases. Three of them showed cerebellar defective lesions on metrizamide CT or RI cisternography. Four of them showed no defective lesion in the posterior fossa on ultrasonography at the early neonatal stage. These lesions in the posterior fossa are believed to be cerebellar porencephaly, which occurred after birth. Seven cases of cerebellar porencephaly, except for one with SFD, had respiratory and cardiovascular diseases, such as neonatal asphyxia, RDS, PDA, and/or apnea. The cerebral lesions such as intracranial hemorrhage, hydrocephalus and cerebral porencephaly, which had been observed in all cases of cerebellar porencephaly, finally resulted in cerebral palsy, mental retardation and infantile spasms.

  18. Maternal dental radiography during pregnancy is not associated with term low birth weight

    International Nuclear Information System (INIS)

    Complete text of publication follows. Objective: In a report published in JAMA in 2004, Hujoel and colleagues indicated that maternal dental radiography during pregnancy may be associated with term low birth weight. Interestingly, they concluded that dental radiographies cause measurable radiation doses to the hypothalamus-pituitary-thyroid axis and the radiation effects on this axis is the reason for term low birth weight. On the other hand, low birth weight is the second leading cause of infant death. In this paper the results obtained in a 2 year study conducted at a midwifery hospital in Rafsanjan, IR Iran are reported. Methods: Four hundred seventy-five singleton infants with gestational periods of 37-44 wk born between 2006 and 2007 at the Niknafs Teaching Hospital affiliated with Rafsanjan University of Medical Sciences and met the inclusion criteria were enrolled in the study. Demographic data and clinical findings at birth including gestation age, sex of infant, birth order, season of birth, maternal age, and maternal education were collected from maternal and newborn hospital records and by interviews with parents. Maternal history of exposure to common sources of man-made ionizing and non-ionizing (exposure to radiations emitted by mobile phones, CRTs, cordless phones) radiation before and during pregnancy were carefully recorded. Results: Among the 475 infants who were studied, there were only 15 cases with a history of maternal dental radiography during pregnancy. The average newborn infants' birth weight in non-exposed and exposed (maternal dental radiography during pregnancy) groups were 3166.69±481.31 g and 3118.67±341.42 g respectively. This difference was not statistically significant. Conclusions: In this study, low birth weight was not associated with maternal dental radiography during pregnancy. These results are generally inconsistent with those reported by Hujoel and colleagues.

  20. Impact of birth weight and early infant weight gain on insulin resistance and associated cardiovascular risk factors in adolescence.

    Directory of Open Access Journals (Sweden)

    Signe Fabricius-Bjerre

    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 Birth weight is negatively associated with cardiovascular diseases and diabetes, but the associations are less well-established in developing populations where birth weight is often unavailable. We studied the association of birth weight and cardiovascular risk, using birth rank as an instrumental variable, in Southern China. Methods We used published data on birth weight by birth rank from an appropriate population and baseline data from the Guangzhou Biobank Cohort Study phases 2 & 3 (2005-8 to examine the adjusted associations, using instrumental variable analysis, of birth weight with clinically measured cardiovascular risk factors and the metabolic syndrome in older (≥ 50 years men (n = 5,051 and women (n = 13,907. Results Estimated birth weight was associated with lower blood pressure (systolic -0.25 mm Hg 95% confidence interval (CI, -0.53 to 0.03 and diastolic -0.33 mm Hg 95% CI -0.48 to -0.18 per standard deviation higher birth weight, but had little association with glucose, lipids, waist-hip ratio, body mass index or the metabolic syndrome, adjusted for age, sex, early environment and number of offspring. Conclusion Birth weight may impact blood pressure; however associations of birth weight with other cardiovascular risk factors may not be related to foetal exposures, but speculatively could be an historical co-incidence, with corresponding implications for prevention.

    Full Text Available Four half-sib families (n = 382 consisting predominantly of ITT x Merino x Merino backcross progeny, including some F2 progeny were used to analyze QTL for two production traits (Birth weight = BW1 and Body weight at 360 days = BW360. The study exploited differences in weight performance between the Merino and ITT sheep. A total of 141 informative microsatellite markers were used in a genome-wide scan covering the 26 autosomal sheep chromosomes. QTL analysis was conducted online using QTL Express. This study reports the effect of QTL for birth weight on Chromosomes 5 (p < 0.05 at 112cM (0cM-128cM. Location of candidate genes for birth weight was predicted at the region of flanking markers MCM527-BMS1247. A QTL for BW360 days existed on Chromosome 18 (p < 0.01 at 104cM (25.0-125cM. Location of candidate genes related to production traits for body weight 360 days was predicted at the segment of flanking markers of CSSM018-TMR1. Only the QTL on Chromosome 18 retained significance (p < 0.01 under experiment-wide significance testing. This QTL region is being examined for candidate genes by investigating to the homologous human chromosomal segments.

    A cross-sectional study was performed to evaluate factors which influence birth weights of beef suckler calves in Norway. Data were from a national beef cattle registry, and lifetime production data of cows slaughtered between January 2010 and January 2013 were included in the study population. The study population consisted of 20,541 cows and 53,819 calves. The analysis was performed on the subset of singleton calvings from which birth weights were recorded. The study sample consisted of 9903 cows with birth weights available for 29,294 calves. The mean birth weight was 43.47kg (95% CI 43.40; 43.53). Two multilevel linear regression models were built; the first was for all calves and included parity of dam as one of the explanatory variables (with herd and cow as random effects), the second model was for calves born to primiparous dams only where age of first calving was included as an explanatory variable (with a random herd effect). The multilevel regression models estimated that female calves were 2.3kg lighter than males (95% CI 2.2-2.4, Pheifer models, respectively), and both the herd and cow random effects were highly significant. In conclusion, birth weights of beef calves in the Norwegian Beef Cattle Recording System were influenced by sex of the calf, breed of the dam, parity, age at first calving, calving season, cow, herd and region.

    Full Text Available Prenatal chemical exposure has been frequently associated with reduced fetal growth by single pollutant regression models although inconsistent results have been obtained. Our study estimated the effects of exposure to single pollutants and mixtures on birth weight in 248 mother-child pairs. Arsenic, copper, lead, manganese and thallium were measured in cord blood, cadmium in maternal blood, methylmercury in maternal hair, and five organochlorines, two perfluorinated compounds and diethylhexyl phthalate metabolites in cord plasma. Daily exposure to particulate matter was modeled and averaged over the duration of gestation. In single pollutant models, arsenic was significantly associated with reduced birth weight. The effect estimate increased when including cadmium, and mono-(2-ethyl-5-carboxypentyl phthalate (MECPP co-exposure. Combining exposures by principal component analysis generated an exposure factor loaded by cadmium and arsenic that was associated with reduced birth weight. MECPP induced gender specific effects. In girls, the effect estimate was doubled with co-exposure of thallium, PFOS, lead, cadmium, manganese, and mercury, while in boys, the mixture of MECPP with cadmium showed the strongest association with birth weight. In conclusion, birth weight was consistently inversely associated with exposure to pollutant mixtures. Chemicals not showing significant associations at single pollutant level contributed to stronger effects when analyzed as mixtures.

    Full Text Available The objective of this study is to determine risk factors causing increase in very low birth way (VLBW neonatal mortality. The medical files of all neonates weighing ≤1500 g, born in Vali-e-Asr hospital (2001-2004 were studied. Two groups of neonates (living and dead were compared up to the time of hospital discharge or death. A total of 317 neonates were enrolled. A meaningful relationship existed between occurrence of death and low gestational age (P=0.02, low birth weight, lower than 1000 g (P=0.001, Apgar score <6 at 5th minutes (P=0.001, resuscitation at birth (P=0.001, respiratory distress syndrome (P=0.001 need for mechanical ventilation (P=0.001, neurological complications (P=0.001 and intraventricular hemorrhage (P=0.001. Regression analysis indicated that each 250 g weight increase up to 1250 g had protective effect, and reduced mortality rate. The causes of death of those neonates weighting over 1250 g should be sought in factors other than weight. Survival rate was calculated to be 80.4% for neonates weighing more than 1000 g. The most important high risk factors affecting mortality of neonates are: low birth weight, need for resuscitation at birth, need for ventilator use and intraventricular hemorrhage.

  10. Low birth weight of contemporary African Americans: an intergenerational effect of slavery?

    Jasienska, Grazyna

    2009-01-01

    The average birth weight in the contemporary African-American population is about 250 g lower than the average birth weight of European Americans. Differences in genetic and socioeconomic factors present between these two groups can explain only part of birth weight variation. I propose a hypothesis that the low birth weight of contemporary African Americans not only results from the difference in present exposure to lifestyle factors known to affect fetal development but also from conditions experienced during the period of slavery. Slaves had poor nutritional status during all stages of life because of the inadequate dietary intake accompanied by high energetic costs of physical work and infectious diseases. The concept of "fetal programming" suggests that physiology and metabolism including growth and fat accumulation of the developing fetus, and, thus its birth weight, depend on intergenerational signal of environmental quality passed through generations of matrilinear ancestors. I suggest that several generations that have passed since the abolition of slavery in the United States (1865) has not been enough to obliterate the impact of slavery on the current biological and health condition of the African-American population.

    The purpose of this study was to analyze the expression of the placenta-specific microRNA miR-517a in maternal serum and in placental tissue from low birth weight newborns and try to detect the effects of miR-517a expression on invasion potential of trophoblasts. Placental tissue and maternal serum were collected from both low birth weight newborns (n = 10) and normal birth weight newborns (n = 20). Expression of miR-517a was assessed in placenta and serum samples by real-time qRT-PCR. In addition, human trophoblast HTR8/SVneo cells were transfected with a miR-517a 2'-O-methyl oligonucleotide or a negative control RNA, and invasion was measured using transwell migration assays. Expression of miR-517a was significantly increased in placentas from low birth weight newborns (61.79 ± 23.06) in comparison with those of normal birth weight newborns (5.01 ± 1.97; P inhibited invasion of HTR8/SVneo cells (P inhibition of trophoblast invasion.

    A link exists between low birth weight and diseases in adulthood, such as hypertension, cardiovascular disease, and insulin resistance. Intrauterine growth restriction (IUGR) has been used to explain this association and has been shown to lead to a nephron endowment in humans. A reduction in...... glomerular number has been described in animal models with induced low birth weight as well but not in animals with spontaneous low birth weight. It therefore is debatable whether the models are suitable. The effect on glomerular number and size was studied in rats with naturally occurring IUGR and...... experimental IUGR, induced by bilateral uterine artery ligation. Design-based stereologic methods were used. Urinary protein excretion was determined as a measure of renal damage. Results showed a decrease of approximately 20% in glomerular number in both groups of IUGR (control 35,400, naturally occurring...

    Full Text Available Objectives: To study the correlation between Body Mass Index (BMI in antenatal period and birth weight of child, along with the socio-demographic determinants of birth weight. Methods: A longitudinal study of one-year duration, from June 2010 to May 2011, was conducted in an urban slum of Mumbai, India. Universal sampling method was employed, including as subjects all pregnant women with minimum two Antenatal Care (ANC visits - and at least one in the third trimester - registered at an urban health centre from June to August 2010. Subjects with any pre-existing co-morbid illness or with past history of giving birth to twins or to any congenitally malformed child, or else, with outcome of still births or home delivery, were excluded. These women were followed up for the next months until delivery. Maternal weight was recorded at each visit and BMI was calculated, or the average BMI, in case of more than one visit in any trimester. Birth weight was recorded using hospital or maternity home records. Results: Prevalence of low birth weight was 26.7%. Correlation between maternal BMI of third trimester and neonatal birth weight was moderately positive. 60.8% of variability in birth weight can be predicted by maternal BMI in third trimester. Conclusions: Third trimester BMI can be used as a predictor of neonatal birth weight. Information, Education and Counseling (IEC activities regarding utilization of Antenatal Care (ANC services can help reducing the incidence of Low Birth Weight (LBW.

    Full Text Available This study was undertaken in Gaza, Palestine, in a cohort of babies born in 2011. Hair samples of newborns were analyzed for metal load by DRC-ICP-MS. We report specific level of contamination by teratogen/toxicants metals of newborn babies, environmentally unexposed, according to their phenotypes at birth: normal full term babies, birth defects or developmentally premature. The occurrence of birth defects was previously shown to be correlated in this cohort to documented exposure of parents to weapons containing metal contaminants, during attacks in 2009. We detect, in significantly higher amounts than in normal babies, different specific teratogen or toxicant elements, known weapons’ components, characteristic for each of birth defect or premature babies. This is the first attempt to our knowledge to directly link a phenotype at birth with the in utero presence of specific teratogen and/or toxicant metals in a cohort with known episodes of acute exposure of parents to environmental contamination by these same metals, in this case delivered by weaponry The babies were conceived 20–25 months after the major known parental exposure; the specific link of newborn phenotypes to war-remnant metal contaminants, suggests that mothers’ contamination persists in time, and that the exposure may have a long term effect.

    Full Text Available Objective: To identify the relationship between periodontitis in pregnant women through the periodontal disease index (PDI and low birth weight babies. Methods: A case-control study was conducted to determine the relationship between periodontitis in pregnant women through the periodontal disease index (PDI and the low birth weight babies (LBW. The participants were mothers with periodontitis and non-periodontitis mothers aged 20–35 years who gave birth in the Department of Obstetrics and Gynecology-Dr. Hasan Sadikin General Hospital, Bandung in the period of December to January 2005. Results: Based on the chisquare test results a highly significant relationship between periodontitis and low birth weight (p=0.002 was found. The Odd’s ratio showed that the risk of low birth weight in pregnant women with periodontitis was 15.58 times higher compared to those who did not suffer from periodontitis. The periodontal disease index has an accuracy of 88.6% in predicting the incidence of LBW. It strongly influenced the incidence of LBW with a high Odd’s ratio of 28.0. Pregnant women who suffer from periodontitis with a PDI > 3.25, have 19.2 times higher risk for delivering babies with LBW compared to the non-periodontitis mothers. Conclusions: The loss of attachment affects the possibility of delivering LBW babies.

    Braham-Hereford F1 dams have been used to evaluate the influence of grazing pressure on forage attributes and animal performance at the Texas A&M University Agricultural Research Center at Overton. Data for this study were compiled from 1,909 records of Simmental-sired calves born to Braham-Hereford F1 cows from 1975 to 1990. Birth weight and weaning weight were analyzed independently to estimate the influence of year, season of birth, dam age, weaning age, and sex of calf. The effect of stocking rate as represented by levels of forage availability on weaning weights and subsequent birth weights was measured. Within the fall and winter calving seasons, lactating dams grazing at a high stocking rate produced calves with the lowest subsequent birth weights. Lactating dams assigned to creep-fed treatments had calves with the heaviest subsequent birth weights. Although dams that were less than 3.5 yr of age had calves with the lightest birth weights, there was no apparent decline in birth weight of calves from dams 12 to 17 yr old. Year, sex of calf, age of dam, stocking rate, season of birth, age at weaning, and birth weight were significant factors affecting weaning weight (P less than .01). Fall-born calves grazing cool-season annual pastures were heavier at weaning (267.6 kg) than either winter- (252.0 kg) or spring-born calves (240.9 kg). A stocking rate x season-of-birth interaction was observed for birth weight and weaning weight (P less than .05). Differences in weaning weight from low- vs high-stocked pastures were greater for fall-born calves (61.6 kg) than for winter-born calves (48.7).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1506293

    Full Text Available Respiratory morbidity in the first two years of life, including recurrent symptoms and frequent hospitalizations, is a common problem in very preterm and very low birth weight (VLBW infants. We conducted a retrospective cohort study aiming to describe the respiratory morbidity at 2 years of corrected age for very preterm and VLBW infants and to identify potential risk factors for its development in a Portuguese based population born in a tertiary referral center between 2009 and 2011. Data were collected from patient’s clinical files and using a standardized questionnaire-based clinical interview for parents. A total 59 children were included. Thirteen (22.0% had recurrent respiratory symptoms and 12 (20.3% were using chronic respiratory medication. Health care utilization for respiratory causes was frequent (57.6%, particularly emergency department attendance (50.8%. Twenty seven (45.8% had additional outpatient visits for respiratory causes and hospital admission was necessary for 8 (13.6% patients. Factors associated with increased recurrent respiratory symptoms included maternal hypertensive disorders during pregnancy, umbilical artery flow disturbances, being small for gestational age, bronchopulmonary dysplasia, retinopathy of prematurity, intraventricular hemorrhage and a weight percentile below 3 at 6, 12 and 24 months of corrected age. Premature rupture of membranes was negatively associated with respiratory morbidity. Respiratory morbidity at 2 years of age is a common problem in very preterm and VLBW children from our population. Several perinatal and developmental risk factors were identified for respiratory morbidity. Further studies are needed to clarify the importance of these factors, as they can lead to changes in healthcare guidelines.

    Relationships between prenatal exposure to fine particles (PM{sub 2.5}) and birth weight have been observed previously. Few studies have investigated specific constituents of PM{sub 2.5}, which may identify sources and major contributors of risk. We examined the effects of trimester and full gestational prenatal exposures to PM{sub 2.5} mass and 23 PM{sub 2.5} constituents on birth weight among 646,296 term births in California between 2000 and 2006. We used linear and logistic regression models to assess associations between exposures and birth weight and risk of low birth weight (LBW; <2500 g), respectively. Models were adjusted for individual demographic characteristics, apparent temperature, month and year of birth, region, and socioeconomic indicators. Higher full gestational exposures to PM{sub 2.5} mass and several PM{sub 2.5} constituents were significantly associated with reductions in term birth weight. The largest reductions in birth weight were associated with exposure to vanadium, sulfur, sulfate, iron, elemental carbon, titanium, manganese, bromine, ammonium, zinc, and copper. Several of these PM{sub 2.5} constituents were associated with increased risk of term LBW. Reductions in birth weight were generally larger among younger mothers and varied by race/ethnicity. Exposure to specific constituents of PM{sub 2.5}, especially traffic-related particles, sulfur constituents, and metals, were associated with decreased birth weight in California. -- Highlights: • Examine full gestational and trimester fine particle and its constituents on term birth weight. • Fine particles and several of its constituents associated with birth weight reductions. • Largest reductions for traffic-related particles, sulfur constituents, and metals. • Greater birth weight reductions for younger mothers, and varied by race/ethnicity.

  12. The relationship between air pollution and low birth weight: effects by mother's age, infant sex, co-pollutants, and pre-term births

    International Nuclear Information System (INIS)

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

    Full Text Available Essential hypertension in children is a very important biological aspect in child pathology, caused by the synergic action of multiple risk factors, with an increasing prevalence. Since there is not much knowledge about juvenile essential hypertension in childhood, in this paper we will clarify the existing data about this pathology and its management, mainly by referring to the correlations during different stages. We found significant correlations between hypertension and the individual values of birth weight and gestational age, which suggest that there is an important relationship between birth weight and gestational age, as important biological markers vs. the different stages of essential hypertension.

    Full Text Available Research Question: What is the influence of maternal nutritional status during pregnancy on the birth weight? Objective: To assess the effect of maternal nutritional status during pregnancy on the birth weight of the baby among tea tribe women in Dibrugarh district. Study Design: Field-based cohort study. Setting: Five tea estates in Dibrugarh District, Assam. Period of Study: One year (April 1998 to April 1999. Participants: A cohort of non-pregnant currently married tea garden women of reproductive age group (15-44 years from similar socio-economic background. Materials and Methods: Oral questionnaire for age, family structure, obstetric history, annual income, and period of gestation. Anthropometric measurements of weight and height were recorded using bathroom scales and the anthropometric rod. Measurements of weight were repeated during the first, second, and third trimesters of pregnancy. Birth weight of the baby was recorded at delivery, irrespective of the period of gestation and mode of delivery. Statistical Analysis: Correlation co-efficient, standard deviation, and regression analysis. Results and Conclusions: Of all, 88% mothers had pre-pregnant weight of < 45 kg, and 61% babies had birth weight < 2500 gm. Subjects with better pre-pregnant weight had corresponding favorable total weight gain, resulting in better birth weight of the babies. Pre-pregnant weight had direct positive linear relationship with the birth weight. There is a need to improve the nutritional status of the adolescent girl in order to build up her pre-pregnant weight for a favorable birth weight.

The aim of this study is to evaluate the relationship between maternal vitamin D status and neonate’s birth weight.Materials and methods:A cross-sectional, descriptive analytical study was carried out in the nursery ward of 2 hospitals (Tehran-Iran during one year (January 2011- January 2012. One hundred and two neonates were categorized into two groups, neonates with birth weight< 2500 gr (n=52 and neonates with birth weight>2500 gr (n=50. Data regarding medical history, physical examination and anthropometric measurements of neonates were noted in a questionnaire. Birth time blood samples of their mothers were analyzed for serum 25-(OH-vitamin D by ELISA method. Maternal vitamin D status was compared in two groups.Results:Mean maternal vitamin D (vit D level was 31.46 nmol/L. Forty eight percent of mothers had vitamin D deficiency, 27.5% had vit D insufficiency and 24.5% were normal. Mean maternal vitamin D level of LBW neonates was lower than other group; 25.05 vs. 38.13 (p= 0.001. All mothers of neonates with head circumference ≤ 33 cm also had vitamin D deficiency (p= 0.007.Conclusion:Maternal Vitamin Ddeficiency may increase the risk of low birth weight neonate and modifying maternal nutrition behavior and their vit D level could be beneficial on pregnancy outcome.

    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.

    Full Text Available Preterm delivery is the single most important cause of perinatal morbidity and mortality. In Chile, preterm births have increased in the past decade, although neonatal morbidity and mortality attributable to it shows a downward trend, thanks to improvements in neonatal care of premature babies, rather than the success of obstetric preventive and therapeutic strategies. This article describes clinical entities, disease processes and conditions that constitute predisposing factors of preterm birth, as well as an outline for the prevention and clinical management of women at risk of preterm birth.

    In this comparative cross-sectional study, possible associations between maternal anti-HLA class I antibodies and birth weight in neonatal thrombocytopenia are explored. Although commonly detected in pregnancies and generally regarded as harmless, it has been suggested that such antibodies might be associated with fetal and neonatal alloimmune thrombocytopenia (FNAIT). As a link between FNAIT due to human platelet antigen 1a-specific antibodies and reduced birth weight in boys has previously been demonstrated, we wanted to explore whether maternal anti-HLA class I antibodies might also affect birth weight. To examine this, suspected cases of FNAIT referred to the Norwegian National Unit for Platelet Immunology during the period 1998-2009 were identified. Pregnancies where the only finding was maternal anti-HLA class I antibodies were included. An unselected group of pregnant women participating in a prospective study investigating maternal-fetal hemodynamics at the University Hospital North Norway during the years 2006-2010 served as controls. Twenty-nine percent of controls had anti-HLA class I antibodies. The thrombocytopenic neonates had a significantly lower adjusted birth weight (linear regression, P=0.036) and significantly higher odds of being small for gestational age (OR=6.72, P<0.001) compared with controls. Increasing anti-HLA class I antibody levels in the mother were significantly associated with lower birth weight and placental weight among thrombocytopenic neonates, but not among controls. These results indicate that maternal anti-HLA class I antibodies in thrombocytopenic neonates are associated with reduced fetal growth. Further studies are needed to test if placental function is affected.

    Full Text Available BACKGROUND: Low birth weight (LBW is a major public health problem in many developing countries, especially so in India. Although we do not know all the causes of LBW, maternal and environmental factors appear to be significant risk factors in its occurrence. OBJECTIVES: To know the factors affecting the birth weight of a newborn and to estimate the prevalence of LBW. METHODS: The present study was carried out amongst 1138 pregnant women and their newborns residing in area covered by Kinaye Primary Health Centre in rural Karnataka, India. The study was conducted from 1(st June 2008 to 31(st December 2009. RESULTS: The mean birth weight of newborns was 2.6 kg with a range of 1.2 to 3.8 kg. The prevalence of LBW was 22.9%. Among the studied risk factors, 25 of them were significantly associated with the birth weight of a newborn on univariate logistic regression analysis. Maternal education [Odds Ratio (OR 3.2], exposure to passive smoking [OR 2.3], age at first pregnancy ≥25 years [OR 3.6], birth interval <2 years [OR 2.4], previous history of LBW baby [OR 3.3], weight gain ≤4 kg during pregnancy [OR 7.0], maternal weight at last week of gestation ≤45 kg [OR 2.3], pregnancy induced hypertension [OR 3.3], high risk pregnancy [OR 3.6] and late antenatal registration [OR 3.6] emerged as significant risk factors on multivariate analysis. CONCLUSION: The problem of LBW is multidimensional, and hence, we need an integrated approach incorporating medical, social, economical and educational measures to address this issue.

    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

    Very low birth weight (VLBW) children are at high risk of perinatal white matter injury, which, when subtle, may not be seen using conventional magnetic resonance imaging. The relationship between clinical findings and fractional anisotropy (FA) measurements in white matter of adolescents born prematurely with VLBW was studied in 34 subjects (age = 15 years, birth weight children semistructured interview, the Autism Spectrum Screening Questionnaire and attention deficit hyperactivity disorder (ADHD) rating scale IV. Overall functioning was scored on the children's global assessment scale. DTI scans were performed for calculation of FA maps and areas of significant differences in mean FA values between subjects and controls were compared with their clinical data. The VLBW children had reduced FA values in the internal and external capsule, corpus callosum and superior, middle superior and inferior fasciculus. Within this group of children, visual motor and visual perceptual deficits were associated with low FA values in the external capsule, posterior part of the internal capsule and in the inferior fasciculus. Children with low IQ had low FA values in the external capsule and inferior and middle superior fasciculus. Fine motor impairment was related to low FA values in the internal and external capsule and superior fasciculus. Eight VLBW children with inattention symptoms or a diagnosis of ADHD had significantly lower FA values in several areas. Mild social deficits correlated with reduced FA values in the external capsule and superior fasciculus. We conclude that DTI was able to detect differences in FA between VLBW adolescents and controls in several white matter areas at risk of periventricular leucomalacia in VLBW newborns. Our results show that low FA values in these areas were associated with perceptual, cognitive, motor and mental health impairments. These conclusions indicate that perinatal injury of white matter tracts persist with clinical significance in

    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.

    Full Text Available ABSTRACT Introduction: Birth weight has been considered an important marker of the nutritional transition in developing countries. Objective: To evaluate the influence of birth weight on body composition and physical fitness of young men born in Maputo, Mozambique. Methods: One hundred and seventy-nine students (aged 19 to 22 years were divided into four groups (low birth weight 3.999 g, HBW, n = 31. Anthropometry and body composition were measured. Physical fitness was assessed by handgrip strength, muscle endurance, flexibility, agility, and running speed. Results: IBW showed lower values of body mass and fat free mass while LBW and HBW had high values of hip circumference, suprailiac, subscapular and abdominal skinfold when compared to NBW. LBW and HBW showed a high percentage of individuals with low performance in flexibility, right handgrip, agility, abdominal resistance, arms strength, and horizontal long jump. Around 70% of HBW showed low performance in the running speed test. Conclusion: Both low and high birth weight can influence adult adiposity and the performance in physical fitness tests.

    Background: Women engaged with polycystic ovarian syndrome (PCOS), as the commonest endocrine disorder, are known to have a specific type of adiposity. Birth weight is among different contributors reported to be responsible for this diversity. Objective: We aimed to compare the relation between birth weight and body fat mass (BFM)/ body lean mass (BLM) in PCOS and their age and body mass index (BMI) matched normal controls. Materials and Methods: In this case-control study, a total number of 70 reproductive aged women, diagnosed with PCOS and 70 age- BMI matched healthy women without hirsutism and/or ovulatory dysfunction were recruited., control group had no polycystic ovaries in ultrasonographic scans. A detailed history of birth weight was taken and was divided into the following categories: PCOS than in controls (19.3% (27) vs. 15.7% (22)). Also body fat and lean mass (BFM, BLM) have increased in adult women with PCOS who were born underweight compared to their normal (19.8±9.05 vs. 12.9±4.5, p=0.001 and 48.9±6.9 vs. 43.2±5.8, p=0.004 respectively). Conclusion: Fetal birth weight influences on the adulthood obesity, BFM and BLM. This impact is different among women with and without PCOS. PMID:27326419

DATA SOURCES: Electronic search of the MEDLINE, Lilacs and SciELO databases from 1990 to 2004, with a selection made of the most relevant articles. Documents and reports from the Ministry of Health (Mortality Information System - SIM and Live Births Information System - SINASC. SUMMARY OF FINDINGS: The decrease in infant mortality rates and the high incidence of maternal deaths, observed since 1990, prompted de Brazilian government to focus its strategies on the organization and delivery of care to pregnant women and their newborn infants. However, a critical analysis of the actions aimed at the care of premature infants reveals that the coverage and utilization of these services are not uniform and that the records on birth and death rates are not reliable. The availability of neonatal beds is very limited and does not meet the demand, especially for those requiring high levels of complexity. Important challenges must be overcome to adequately deal with the incorporation of inappropriate technology, the limited number of qualified health professionals and utilization of evidence-based best practices to improve perinatal care. CONCLUSIONS: A reduction in the rates of morbidity and mortality of premature infants requires more effective planning and intervention in the prenatal care system. To meet the demand, increases in the number of neonatal intensive care beds should be implemented through specialized perinatal centers rather than

  19. Interrelationships between Cd, Zn and birth weight in neonates of women who smoke

    International Nuclear Information System (INIS)

    A study was designed to test the hypothesis that the increased cadmium level in pregnant women who smoke alters the metabolism of zinc in the maternal-fetal unit, and that this altered Zn metabolism may contribute to lower birth weight infants. One hundred-thirty mother/infant pairs were studied. Maternal whole blood and placental Cd were analyzed by graphite furnace atomic absorption spectrophotometry; maternal and fetal plasma, red blood cell and placental Zn by flame atomic absorption spectroscopy. Maternal plasma thiocyanate (SCN) levels were used as an index of smoking status. Zn intake was estimated by diet history in a subgroup of 34 patients. The data were analyzed using t-tests, correlation and stepwise multiple regression techniques. No differences in Zn intake were found between pregnant women who smoked and those who did not. The average daily intake of Zn was 10.2 +/- 5 mg; this is less than the RDA for Zn during pregnancy. The data show that there are significant positive correlations between SCN levels and levels of whole blood Cd, placental Cd, and placental Zn. Cord vein samples from infants of mothers who smoked had decreased red blood cell Zn. This was particularly true in nulliparous patients. In all patients, maternal whole blood Cd was found to be negatively related to birth weight and cord vein red blood cell Zn was positively related to birth weight. The results support the hypothesis of a Cd-Zn interaction in pregnant women who smoke. Additional findings suggest an effect of parity on the interaction between Cd and Zn. Placental Cd was found to be negatively related to birth weight in nulliparous patients (n=21). In multiparous patients (n=109) placental Zn was inversely related to birth weight. In patients with parity 2 or greater (n=54), placental Cd was directly predictive of placental Zn. These results may reflect a less favorable Zn nutritional status with increasing parity

    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 Background: This study have conducted in order to determine of direct or indirect effective factors on mortality of neonates with low birth weight by path analysis.Methods: In this cohort study 445 paired mothers and their neonates were participated in Tehran city. The data were gathered through an answer sheet contain mother age, gestational age, apgar score, pregnancy induced hypertension (PIH and birth weight. Sampling was convenience and neonates of women were included in this study who were referred to 15 government and private hospitals in Tehran city. Live being status of neonates was determined until 24 hours after delivery.Results: The most changes in mortality rate is related to birth weight and its negative score means that increasing in weight leads to increase chance of live being. Second score is related to apgar sore and its negative score means that increasing in apgar score leads to decrease chance of neonate death. Third score is gestational age and its negative score means that increasing in weight leads to increase chance of live being. The less changes in mortality rate is due to hypertensive disorders in pregnancy.Conclusion: The methodology has been used could be adopted in other investigations to distinguish and measuring effect of predictive factors on the risk of an outcome.

Inadequate birth weight is a major concern to public health given it has been associated with increasing morbidity-mortality during the first year of life and with increased risks of

  3. Cognitive function and MRI findings in very low birth weight infants

    International Nuclear Information System (INIS)

    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 (T2-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 An analysis of the neonatal registry for 2001-2010 years in Rivne and Volyn regions of Ukraine as well as 2006-2011 years of Khmelnytsky region was carried out. General information was available about body weight of 366 607 newborns, among which 188 687 were boys and 177 920 girls. Based on the analysis we developed local standards of birth body weight in relation to gestational age separately for boys and girls. Procedure for processing local standards met international standards that have been developed by the WHO. Availability of processed local standards depending on gestational age will enable neonatologists, pediatricians and researchers to clearly identify anomalies in the health of newborns in the northwestern regions of Ukraine. Therefore, identification of newborns with low or high birth weight will enable adequate and timely steps to improve their health.

    Very low birth weight infants (VLBW; birth weightphthalates from medical devices during their hospital stay. We measured urinary phthalate concentrations among hospitalized VLBW infants participating in a nutritional study. Possible associations between different phthalates and birth weight (BW), septicemia and bronchopulmonary dysplasia (BPD) were evaluated. Forty-six VLBW infants were enrolled in this randomized controlled nutritional study. The intervention group (n=24) received increased quantities of energy, protein, fat, essential fatty acids and vitamin A, as compared to the control group (n=22). The concentrations of 12 urinary phthalate metabolites were measured, using high-performance liquid chromatography coupled to tandem mass spectrometry, at 3 time points during the first 5weeks of life. During this study, the levels of di (2-ethylhexyl) phthalate (DEHP) metabolites decreased, whereas an increasing trend was seen regarding metabolites of di-iso-nonyl phthalate (DiNP). Significantly higher levels of phthalate metabolites were seen in infants with lower BW and those diagnosed with late onset septicemia or BPD. A significant positive correlation between the duration of respiratory support and DEHP metabolites was observed (p≤0.01) at 2.9weeks of age. Birth weight was negatively associated with urinary phthalate metabolite concentrations. Infants with lower BW and those diagnosed with septicemia or BPD experienced prolonged exposure from medical equipment containing phthalates, with subsequent higher levels of phthalate metabolites detected.

    Full Text Available Background Low birth weight (LBW is closely related to neonatal morbidity and mortality. Management of LBW infants in developing countries remains limited, due to the low availability of incubators. The Kangaroo Mother Care (KMC method has been shown to be effective for newborns, especially LBW infants, in which skin-to-skin contact may be conducive for infants’ weight gain, thermoregulation, and heart rate stability.Objective To determine the prognostic factors for KMC success in LBW babies.Methods This cohort study included LBW infants at Dr. Kariadi General Government Hospital, Semarang, by a consecutive sampling method. Success of KMC was assessed by infant weight gain, as well as stabilization of temperature, heart rate, and respiration. Prognostic factors for KMC success that we assessed were birth weight, gestational age, KMC duration, age at KMC onset and maternal education level. Statistical analyses used were Chi-square and relative risk (RR tests.Results Of 40 LBW infants, 24 were successful in KMC. Birth weight ≥ 1500 grams (RR 0.4; 95%CI 0.23 to 0.73; P=0.001], gestational age ≥ 34 weeks (RR 0.94; 95%CI 0.46 to 1.89; P=1.00, KMC duration ≥ 65 minutes (RR 1.44; 95%CI 0.76 to 2.75; P= 0.215, high maternal education level (RR 1.25; 95%CI 0.76 to 2.04; P=0.408, and age at KMC onset >10 days (RR 2.69; 95%CI 1.14 to 6.32; P=0.003, were factors that related to the successful of KMC.Conclusion Age at KMC onset > 10 days was a prognostic factor for KMC success in low birth weight babies.

    Birth weight is the single most important risk indicator for neonatal and infant mortality and morbidity, which has led to the idiom that 'every ounce counts'. Birth weight in turn, however, tends to vary widely across populations as a result of differential fetal growth velocity with such demographic factors as ethnicity, maternal and paternal height and altitude of residence. Accordingly, it has been acknowledged that the appraisal of birth weight should rely on its position relative to the birth weight distribution of the background population. This is commonly done by standardizing birth weight through its deviation from the population mean in the given gestational age stratum, as can be obtained from population-customized birth weight nomograms. This issue was recently revisited in 'Human Reproduction' through a plea for reporting birth weight as z-scores. In this article, we argue that adjustment for factors, such as gestational age, which may lie on the causal pathway from exposures present at the time of conception [e.g. single-embryo transfer (SET) versus double-embryo transfer (DET)] to birth weight, may induce bias, regardless of whether the adjustment happens via stratification, regression or through the use of z-scores.

    Our objective was to determine the risks of preterm birth (PTB) and low birth weight (LBW) in singletons conceived through in vitro fertilization (IVF)+/-intracytoplasmic sperm injection (ICSI) compared to spontaneously conceived singletons after matching or controlling for at least maternal age. The MOOSE guidelines for meta-analysis of observational studies were followed. Medline and Embase were searched using comprehensive search strategies. Bibliographies of identified articles were reviewed. English language studies examining LBW or PTB in singletons conceived by IVF or IVF/intracytoplasmic sperm injection, compared with spontaneously conceived singletons, that matched or controlled for at least maternal age. Two reviewers independently assessed titles, abstracts, full articles and study quality and extracted data. Dichotomous data were meta-analyzed using relative risks (RR) as measures of effect size with a random effects model and for continuous data weighted mean difference was calculated. Seventeen studies were included with 31,032 singletons conceived through IVF (+/-ICSI) and 81,119 spontaneously conceived singletons. After matching or controlling for maternal age and often other factors, compared to spontaneously conceived singletons, IVF singletons had increased risks of our two primary outcomes, PTB (RR 1.84, 95% CI 1.54, 2.21) and LBW (<2500 g, RR 1.60, 95% CI 1.29, 1.98). Singletons conceived through IVF or IVF/ICSI were at increased risk for late PTB (32-36 weeks, RR 1.52, 95% CI 1.01, 2.30), moderate PTB <32-33 weeks (RR 2.27, 95% CI 1.73, 2.97), very LBW (<1500 g, RR 2.65, 95% CI 1.83, 3.84), and intrauterine growth restriction (RR 1.45, 95% CI 1.04, 2.00), lower birth weights (-97 g, 95% CI -161 g, -33 g) and shorter mean gestations (-0.6 weeks, 95% CI -0.9 weeks, -0.4 weeks). In conclusion, IVF singletons have significantly increased risks of PTB, LBW and other adverse perinatal outcomes compared to spontaneously conceived singletons after

    Birth certificates are an important source of pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) data for surveillance and aetiologic studies, but little is known about their validity in twin pregnancies. Twins experience high rates of adverse perinatal outcomes that have been associated with BMI and GWG in singletons. Our objective was to evaluate the accuracy of birth certificate-derived pre-pregnancy BMI and GWG compared with medical record-derived data in a sample of 186 twin pregnancies at a teaching hospital in Pennsylvania (2003-2010). Twelve strata were created by simultaneous stratification on pre-pregnancy BMI (underweight, normal weight/overweight, obese class 1, obese classes 2 and 3) and GWG (80th percentile). The agreement of birth certificate-derived pre-pregnancy BMI category with medical record BMI category was lowest among underweight mothers [75% (95% confidence interval 51-91%) ] and highest among normal/overweight [97% (90-99%) ] and obese classes 2 and 3 mothers [97% (85-99%) ]. Agreement for GWG category from the birth certificate varied from 57% (41-70%) for GWG >80th percentile to 80% (65-91%) and 82% (72-89%) for GWG <20th and 20th-80th percentiles, respectively. The misclassification of BMI and GWG was primarily due to error in pre-pregnancy weight rather than weight at delivery or height. Agreement proportions for twins were not meaningfully different from the proportions in a comparable sample of singleton pregnancies. These data suggest that birth certificate-based BMI and GWG data are prone to error in twin pregnancies. Those who use these data should conduct internal validation studies and adjust their results using bias analyses. PMID:25522306

  18. Increased birth weight associated with regular pre-pregnancy deworming and weekly iron-folic acid supplementation for Vietnamese women.

    Directory of Open Access Journals (Sweden)

    Luca Passerini

    Full Text Available BACKGROUND: Hookworm infections are significant public health issues in South-East Asia. 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.

    Full Text Available Introduction: There is an overwhelming body of evidence strongly suggesting that periodontal infection may have a significant negative impact on pregnancy outcome in some women. The aim of this study was to determine the association, if any, between periodontal disease and preterm low birth weight. Materials and Methods : A total of 211 mothers between the ages of 17 and 35 were grouped into two categories based on the gestational age and weight of the baby as cases (< 37 weeks, < 2500 g and controls (>37 weeks, >2500 g. Relevant obstetric history and information on other primary risk factors for preterm low birth weight were obtained. Investigation reports on blood group, Rh factor and hemoglobin (Hb were also gathered. Oral assessments included: simplified oral hygiene index (OHI-S, gingival bleeding index, probing pocket depth and clinical attachment level (CAL. Results: Cases had significantly more attachment loss and probing pocket depth, poor oral hygiene, more percentage of sites with attachment loss (Extent and more mean attachment loss per site (Severity and less Hb than controls. The number of visits for prenatal care and the percentage of sites with CAL≥2mm (Extent 2 remained significant when compared to other variables. Conclusion: The study indicated that periodontal disease is a contributing factor for preterm low birth weight.
