    Full Text Available Abstract Objective: to determine the risk factors for premature birth. Methods: retrospective case-control study of 600 pregnant women assisted in a hospital, with 298 pregnant women in the case group (who gave birth prematurely <37 weeks and 302 pregnant women who gave birth to a full-term newborn in the control group. Stata software version 12.2 was used. The Chi-square test was used in bivariate analysis and logistic regression was used in multivariate analysis, from which Odds Ratios (OR and Confidence Intervals (CI of 95% were derived. Results: risk factors associated with premature birth were current twin pregnancy (adjusted OR= 2.4; p= 0.02, inadequate prenatal care (< 6 controls (adjusted OR= 3.2; p <0.001, absent prenatal care (adjusted OR= 3.0; p <0.001, history of premature birth (adjusted OR= 3.7; p <0.001 and preeclampsia (adjusted OR= 1.9; p= 0.005. Conclusion: history of premature birth, preeclampsia, not receiving prenatal care and receiving inadequate prenatal care were risk factors for premature birth.

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

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

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

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

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

  11. Prematurity at birth and increased cardiovascular risk: is a metabolomic approach the right solution?

    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.

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

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

    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.

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

  4. Premature birth and diseases in premature infants: common genetic background?

    Hallman, Mikko

    2012-04-01

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

    To investigate the utility of vaginal placental alpha microglobulin-1 (PAMG-1) protein as a predictor of preterm delivery within 7 days in pregnancies at risk of premature birth. This prospective study was performed in women at risk of premature birth. The levels of vaginal PAMG-1 and foetal fibronectin (fFN) and the transvaginal cervical length measurement (CLM) were investigated and compared. Seventy-two pregnant women were included in this study. The sensitivities of PAMG-1, fFN and CLM were 73.3, 73.6%, and 52.9%, respectively, while the specificities of PAMG-1, fFN and CLM were 92.9%, 94.3%, and 90.9%, respectively. The positive predictive values of PAMG-1, fFN and CLM were 73.3%, 82.3%, and 64.2%, respectively, and the negative predictive values of PAMG-1, fFN and CLM were 92.9%, 90.9%, and 86.2%, respectively. The diagnostic accuracy of PAMG-1 is similar to that of fFN in terms of preterm labour detection within 7 days.

    2006-01-01

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

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

    To assess the benefits of a chemoprophylaxis program based on screening women for group B streptococcus (GBS) infection between 30 and 32 weeks of pregnancy in a population with a high rate of premature births. From 1995 to 2011, 24 950 women were screened for GBS infection between 30 and 32 weeks of pregnancy at Markusovszky Teaching Hospital, Szombathely, Hungary. Those who tested positive, and those who tested negative but were at risk of infecting their newborns, underwent intrapartum prophylaxis. Neonatal outcomes were compared with those of a historical cohort that underwent no screening or treatment, and with those published in CDC/ACOG guidelines recommending screening closer to term. There were 63 infected newborns (0.2%) in the study cohort, and 1 of 8 with sepsis died. There were 149 infected newborns (0.7%) in the historical cohort, and 29 of 31 with sepsis died. Screening women early in a population with a high rate of premature births may simplify preterm labor management. It results, however, in a higher incidence of early onset neonatal GBS disease than when screening is done closer to term. Copyright © 2013 International Federation of Gynecology and Obstetrics.

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

    Risk of premature birth was evaluated retrospectively in 610 women in the first days after delivery using the prematurity risk score published by Thalhammer 1973. The calculated risk of premature birth was compared than prospectively to postpartal morbidity of the newborn infants as determined by duration of hospital stay, incidence of respiratory distress syndrome, need of artificial ventilation and mortality. A positive correlation could be found between risk of premature birth and postpartal morbidity of the newborn infants especially in small premature infants with birthweights of 2000 grams and less. The same correlation existed also in two groups of infants out of two different obstetric clinics which showed the same distribution of prenatal risks and the same prenatal care frequencies. It clearly becomes evident that infants with the same prenatal risks but good prenatal care during pregnancy had much lower hospital stays, lower respiratory distress frequencies and lower mortality rates than babies delivered from pregnancies badly cared for. These prenatal care related differences in postpartum morbidity again were much more evident in infants out of lower birth weight classes.

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

    Aim: The study explored fathers’ experience of premature birth during the hospitalization of their infants, analyzing levels of depressive and anxiety symptoms as compared with mothers. Moreover the Italian version of the Clinical Interview for Parents of High-Risk Infant (CLIP) was tested through confirmatory factor analysis. Methods: Couples of parents (N = 64) of preterm infants (gestational age < 37 weeks) were administered a socio-demographic questionnaire, the Edinburgh Postnatal Depression Scale, the State-Trait Anxiety Inventory and the CLIP after the admission to the Neonatal Intensive Care Unit (NICU). Results: Significant levels of anxiety and depressive symptoms and high percentages of subjects above the corresponding risk thresholds were found among fathers and mothers with higher scores among the latters. Confirmatory factor analysis of the CLIP showed an adequate structure, with better fit for mothers than for fathers. Conclusion: Results highlighted the importance for nurses and clinicians working in the NICU to consider not only the maternal difficulties but also the paternal ones, even if these are often more hidden and silent. In addition the CLIP may be considered an useful interview for research and clinical purposes to be used with parents of high-risk infants. PMID:26483712

    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.

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

    2012-01-01

    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.

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

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

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

    Conclusions: The rate of Type I ROP in this study is higher than that in previous studies due to the higher number of infants with BW <1000 g in our cohort and the treatment of more eyes with stage 2+ ROP. However, all the treated eyes had a favorable outcome. Gestational age at birth and number of ventilated days were independent risk factors for the development of Type I ROP.

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

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

    Full Text Available Intraventricular hemorrhage (IVH is an important cause of brain injury in premature neonates. Current study tries to define associated risk factors of IVH in preterm neonates in Aliasghar Children Hospital during 2008 to 2011. In this study, the risk factors have been evaluated in premature neonates with IVH, who had at least one brain sonography since their admission in NICU. A total of 63 premature neonates with IVH were assessed. Mean gestational age was 29.81 (24-34 weeks and mean birth weight was 1290.83±382.96 gr. Other risk factors such as sex, mode of delivery, history of using infertility drugs, maternal disease, maternal hypertension and preeclampsia, lumbar puncture, ventilator therapy and pneumothorax were considered. Because no absolute treatment for IVH is available, identifying risk factors is important in prevention and management of IVH.

    Women with at least 1 prior occurrence of premature birth often have demographic and medical risk factors that are not modifiable. However, smoking cessation could be a targeted intervention in which a woman with a history of premature birth may be able to reduce her future risk of recurrence. This study aims to assess how trimester-specific smoking patterns influence the risk of recurrent premature birth. This was a population-based retrospective cohort study of singleton nonanomalous live births in Ohio, 2006-2012 using vital statistics birth records. This analysis was limited to women with at least 1 prior premature birth. Rates of birth preterm birth has been studied extensively, and it is widely accepted that smoking in pregnancy increases preterm birth rates. However, this study provides novel information quantifying the risk of recurrent preterm birth and stratifies the increased risk of recurrent preterm birth by trimester-specific smoking behavior. Although women with even 1 prior premature birth are at an inherently high risk of recurrence, women who stopped smoking early in the first 2 trimesters experienced similar preterm birth rates compared with nonsmokers. However, delayed smoking cessation or smoking throughout pregnancy significantly increased recurrent premature birth risk. Smoking cessation is a potential modifiable risk factor for recurrent preterm birth in high-risk pregnancies. This study highlights the importance of early pregnancy smoking cessation in those at especially high risk, women with a prior preterm birth. Copyright © 2016 Elsevier Inc. All rights reserved.

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

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

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.

    Full Text Available Abstract Background Increased survival of extremely low birth infants due to advances in antenatal and neonatal care has resulted in a population of infants at high risk of developing retinopathy of prematurity (ROP. Therapeutic interventions include the use of antenatal and postnatal steroids however, their effects on the severity of ROP is in dispute. In addition, it has not been investigated whether severe ROP is due to therapeutic interventions or due to the severity of illness. The aim of the present study was to assess the association between the incidence of severe retinopathy of prematurity (greater than stage 2 – International classification of ROP and mechanical ventilation, oxygen therapy, gestational age, antenatal and postnatal steroids in extremely low birth weight infants. Methods Neonates admitted to the neonatal intensive care unit in Lansing, Michigan, during 1993–2000 were followed to determine factors influencing the development of severe retinopathy of prematurity. Ophthalmologic examinations were started at 6 weeks and followed until resolution. We used logistic regression to estimate the relative risk (odds ratio associated with risk factors of ROP. Results Of the neonates with ≤ 1500 g birth weight, admitted to the neonatal intensive care unit, 85% (616/725 survived. Severe retinopathy of prematurity was detected in 7.8% of 576 neonates who had eye examinations. Neonates of lower gestational age (≤ 25 weeks and 26–28 weeks had an increased odds ratio of 8.49 and 3.19 for the development of severe retinopathy of prematurity, respectively, compared to those 29 weeks and older. Late postnatal steroid treatment starting after 3 weeks of life showed 2.9-fold increased odds ratio, in particular administration for two weeks and more (OR: 4.09, 95% CI: 1.52–11.03. With increasing antenatal steroids courses the risk of severe retinopathy of prematurity decreased, however, it was not significant. Lower gestational age

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

    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. However, considering the effect of BW and GA, logistic regression analysis revealed no statistically significant difference in the frequency and

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

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

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

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

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

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

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

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

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

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

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

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

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

    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.

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.

    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.

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

    Full Text Available Background: Retinopathy of prematurity (ROP is a serious complication of prematurity treatment and can lead to blindness unless recognized and treated early. Objective: The objective was to estimate the prevalence of ROP in preterm infants in the Neonatal Intensive Care Unit (NICU, to identify the risk factors which predispose to ROP, and to assess the outcome of these cases. Materials and Methods: A ROP prospective screening survey was performed enrolling all prematures admitted to the NICU from January 2009 to December 2010, with a gestational age of 32 weeks or less at birth and a birth weight of 1500 g or less. Infants whose gestational age was >32 weeks or birth weight was >1500 g were included if they were exposed to oxygen therapy for more than 7 days. A total of 172 infants (84 males and 88 females had retinal evaluation by indirect ophthalmoscopy from the fourth postnatal week and followed up periodically. Perinatal risk factors for ROP were assessed using univariate and multivariate analysis. Infants who progressed to stage 3 ROP were given laser therapy. Results: Out of the studied 172 infants, 33 infants (19.2% developed ROP in one or both eyes; 18 (54.5% cases stage 1, 9 (27.3% cases stage 2, and 6 (18.2% cases stage 3. None of the studied neonates presented ROP at stages 4 or 5. The six cases diagnosed as ROP stage 3 underwent laser ablative therapy.

    Preterm birth is the most important cause of neonatal mortality and morbidity worldwide. In this review, we review potential risk factors associated with preterm birth and the subsequent management to prevent preterm birth in low and high risk women with a singleton or multiple pregnancy. A history of preterm birth is considered the most important risk factor for preterm birth in subsequent pregnancy. General risk factors with a much lower impact include ethnicity, low socio-economic status, maternal weight, smoking, and periodontal status. Pregnancy-related characteristics, including bacterial vaginosis and asymptomatic bacteriuria, appear to be of limited value in the prediction of preterm birth. By contrast, a mid-pregnancy cervical length measurement is independently associated with preterm birth and could be used to identify women at risk of a premature delivery. A fetal fibronectin test may be of additional value in the prediction of preterm birth. The most effective methods to prevent preterm birth depend on the obstetric history, which makes the identification of women at risk of preterm birth an important task for clinical care providers.

    Among the clinical factors for preterm birth, some confer substantial increased risk, including a history of preterm birth, multiple gestation and vaginal bleeding in the second trimester. However, these factors are present only in a minority of women who ultimately deliver preterm and thus have low sensitivity. Cervical dilatation, effacement and position as determined by manual examination have been related to an increased risk of preterm birth but also suffer from low sensitivity and positive predictive values. Cervical length measured with transvaginal ultrasound has also been related to an increased risk of preterm birth as cervical length decreases. The reported sensitivity is better than other tests, but positive predictive value is low. The principal utility of the fetal fibronectin assay lies in its negative predictive value in symptomatic women. Increased sensitivity has been reported when cervical length is used in combination with fetal fibronectin.

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

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

    Full Text Available Background: Maternal age is a preponderant variable in the epidemiological analysis of the premature birth. Studies show that in the extreme ages of the maternal life there is a risk of premature birth that generates a high rate of neonatal morbidity. Objetives: Determine the effect on the extreme ages of women residents in the province of Alicante on the total of the premature births. Method: An explanatory, retrospective case-control study was conducted during the period from January 1st, 2008 to December 31st, 2011. The study was based on the revision of the newborn registers from the Neonatal Screening Center of the province of Alicante. All the preterm were included, this means between 22 & 36 complete weeks of pregnancy (5,295 out of 78,391 newborn which represents 6.75% of prematurity, and a random sample of the deliveries with 37 weeks or more of pregnancy (control group. The age of the mother was studied as independent variable and the prematurity as dependent variable. Results: Clearly shows an increased risk of prematurity among teenage mothers compared to the age group nearest to them, which is confirmed by a squared Chi test which gives a significantly different distribution (p < 0,0001 and an OD for very preterm of 2,41 (1,51-3,24 and of preterm of 1,71 (1,32-2,19. This probability is also higher among mothers over 40 years old with an OD of 1,86 (1,39-2,48 and 1,66 (1,44-1,91 for very preterm newborns and preterm newborns respectively. Discussion: The results clearly manifest that teenagers and older pregnant mothers are at higher prematurity and low birth weight risk, therefore imposes the need to trace educational interventions to minimize this problem from the results in this research.

    2013-01-01

    Objective To examine the differences in postneonatal death risk among 3 clinical subtypes of preterm birth: preterm premature rupture of membranes (PROM), indicated preterm birth, and spontaneous preterm labor. Study design We analyzed the 2001–2005 US linked birth/infant death (birth cohort) datasets. The preterm birth subtypes were classified using information on the birth certificate: reported PROM, induction of labor, cesarean section, and complications of pregnancy and labor. Cox proportional hazard models were used to estimate covariate-adjusted hazard ratios and 95% CIs for postneonatal death (from days 28 to 365). Estimation was given for preterm birth subtypes in a week-by-week analysis. Causes of death were analyzed by preterm birth subtype and then separately at 24–27, 28–31, and 32–36 weeks of gestation. Results For the total of 1 895 350 singleton preterm births who survived the neonatal period, the postneonatal mortality rate was 1.11% for preterm PROM, 0.78% for indicated preterm birth, and 0.53% for spontaneous preterm labor. Preterm PROM was associated with significantly higher risk of postneonatal death compared with spontaneous preterm labor in infants born at 27 weeks gestation or later. Similarly, indicated preterm birth was associated with a significantly higher risk of postneonatal death than spontaneous preterm labor in infants born at 25 weeks gestation or later. Preterm PROM and indicated preterm birth were associated with greater risk of death in the postneonatal period compared with spontaneous preterm labor, irrespective of the cause of death. Conclusion Subtypes of preterm birth carry different risks of postneonatal mortality. Prevention of preterm-related postneonatal death may require more research into the root causes of preterm birth subtypes. PMID:22878113

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

    Kelly, Michelle M; Dean, Spencer

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

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

    Full Text Available Background Retinopathy of prematurity (ROP is the main cause of visual impairment in premature infants. Due to advances in neonatal care, the increased survival of extremely low birth weight (ELBW infants in recent years has produced a population of infants at very high risk of ROP. Objective The aims of this study were to determine the prevalence and potential risk factors for ROP. Methods This retrospective study was conducted at the Neonatalogy Ward, Cipto Mangunkusumo Hospital, from January 2005 to August 2010. We included all premature infants of gestational age (GA < 37 weeks, body weight (BW not exceeding 2000 grams, as well as those who had eye examinations and complete medical records. Risk factors such as GA, BW, duration of oxygen (O2 therapy, sepsis, and red blood cell (RBC transfusion were analyzed using the Chi-square and logistic regression tests. Pediatric ophthalmologists had performed eye examinations on all infants. ROP was graded according to the International Classification of ROP. Results The prevalence of ROP and of stage 3 or greater ROP was 11.9% and 4.8% of all subjects, respectively. Body weight, GA, duration of O2 therapy, and sepsis were found to be associated with the development of ROP. However, stepwise logistic regression analysis revealed that only BW of ≤ 1000 g [odds ratio (OR 10.88; 95% CI 3.09 to 38.31; P < 0.000], O2 therapy ≥ 7 days (OR 5.56; 95% CI 1.86 to 16.58; P < 0.0001, and GA of ≤ 28 weeks (OR 4.26; 95% CI 1.15 to 15.81; P = 0.030 were statistically significant risk factors for ROP.

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

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

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

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

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

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

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

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

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

    Science.gov (United States)

    Fant, Michael E.; Fuentes, Juan; Kong, Xiaoyuan; Jackman, Suzanne

    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 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.

    2017-05-01

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

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

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

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

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.

    Full Text Available We aim to determine risk factors and clinical outcomes for bowel perforation in premature infants with NEC. We analyzed clinical data of 57 cases of premature infants with NEC at our NICU between January 2010 and December 2012. Based on the presence of bowel perforation, we divided these infants into two groups: perforated NEC group (n=10 and nonperforated NEC group (n=47. We compared general information, clinical characteristics, and laboratory findings between groups. The perforated NEC group, compared to the nonperforated NEC group, had significantly lesser gestational age, lower birth weight, higher prevalence of apnea, mechanical ventilation, sepsis and shock, lower blood pH, higher levels of blood glucose, abnormal WBC count and thrombocytopenia, and elevated CRP (all P<0.05. Moreover, the perforated NEC group had significantly longer durations of fasting and TPN usage, higher incidences of EUGR and cholestasis, longer duration of antibiotics, higher frequency of advanced antibiotics use, and poorer prognosis than the nonperforated NEC group (all P<0.05. Bowel perforation in premature infants with NEC was associated with multiple risk factors. Early identification of some of these risk factors in premature infants with NEC may help implement early intervention to reduce the incidence of bowel perforation and thereby improve the prognosis.

    Full Text Available Abstract Background The rate of preterm birth has been increasing worldwide, including in Brazil. This constitutes a significant public health challenge because of the higher levels of morbidity and mortality and long-term health effects associated with preterm birth. This study describes and quantifies factors affecting spontaneous and provider-initiated preterm birth in Brazil. Methods Data are from the 2011–2012 “Birth in Brazil” study, which used a national population-based sample of 23,940 women. We analyzed the variables following a three-level hierarchical methodology. For each level, we performed non-conditional multiple logistic regression for both spontaneous and provider-initiated preterm birth. Results The rate of preterm birth was 11.5 %, (95 % confidence 10.3 % to 12.9 % 60.7 % spontaneous - with spontaneous onset of labor or premature preterm rupture of membranes - and 39.3 % provider-initiated, with more than 90 % of the last group being pre-labor cesarean deliveries. Socio-demographic factors associated with spontaneous preterm birth were adolescent pregnancy, low total years of schooling, and inadequate prenatal care. Other risk factors were previous preterm birth (OR 3.74; 95 % CI 2.92–4.79, multiple pregnancy (OR 16.42; 95 % CI 10.56–25.53, abruptio placentae (OR 2.38; 95 % CI 1.27–4.47 and infections (OR 4.89; 95 % CI 1.72–13.88. In contrast, provider-initiated preterm birth was associated with private childbirth healthcare (OR 1.47; 95 % CI 1.09–1.97, advanced-age pregnancy (OR 1.27; 95 % CI 1.01–1.59, two or more prior cesarean deliveries (OR 1.64; 95 % CI 1.19–2.26, multiple pregnancy (OR 20.29; 95 % CI 12.58–32.72 and any maternal or fetal pathology (OR 6.84; 95 % CI 5.56–8.42. Conclusion The high proportion of provider-initiated preterm birth and its association with prior cesarean deliveries and all of the studied maternal/fetal pathologies suggest that a reduction of this type of

    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.

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

    Full Text Available Premature delivery, a significant cause of child mortality and morbidity worldwide, is particularly prevalent in the developing world. As HIV is highly prevalent in much of sub-Saharan Africa, it is important to determine risk factors for prematurity among HIV-positive pregnancies. The aims of this study were to identify risk factors of preterm (<37 weeks and very preterm (<34 weeks birth among a cohort of 927 HIV positive women living in Dar es Salaam, Tanzania, who enrolled in the Tanzania Vitamin and HIV Infection Trial between 1995 and 1997. Multivariable relative risk regression models were used to determine the association of potential maternal risk factors with premature and very premature delivery. High rates of preterm (24% and very preterm birth (9% were found. Risk factors (adjusted RR (95% CI for preterm birth were mother <20 years (1.46 (1.10, 1.95, maternal illiteracy (1.54 (1.10, 2.16, malaria (1.42 (1.11, 1.81, Entamoeba coli (1.49 (1.04, 2.15, no or low pregnancy weight gain, and HIV disease stage ≥2 (1.41 (1.12, 1.50. Interventions to reduce pregnancies in women under 20, prevent and treat malaria, reduce Entamoeba coli infection, and promote weight gain in pregnant women may have a protective effect on prematurity.

    Describe tools designed to predict preterm birth in asymptomatic high-risk pregnancy and determine their predictive value. The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. Obstetric history particularly spontaneous preterm birth identifies a population at risk for preterm birth for the current pregnancy (LE3). This risk is related to the number of prior preterm birth and is even higher than the term of the prior event is more premature and that the event concerns the last pregnancy (LE3). The literature data are insufficient to recommend systematic cervical examination at each prenatal visit in asymptomatic high-risk pregnancy (multiple pregnancy, uterine malformations, history of spontaneous preterm birth, excisional cervical procedure or at least two voluntary first trimester abortion) (professional consensus). Regular recording of uterine activity and home visits for asymptomatic high-risk pregnancy did not predict nor reduce the risk of preterm birth (LE2) and are not recommended (grade B). In asymptomatic high-risk pregnancy, ultrasonographic measurement of cervical length estimates the risk of preterm birth (LE2). Shorter is the cervical length higher is the risk of preterm birth (LE3). In asymptomatic patient with prior preterm birth, ultrasonographic measurement of cervical length estimates the risk of preterm birth (LE2). The strategy of ultrasound indicated cerclage are discussed in dedicated chapter. The measurement of cervical length by transvaginal ultrasonography in asymptomatic pregnancy with uterine malformation, a history of cervical treatment, at least two voluntary abortions or having a multiple pregnancy would estimate the risk of preterm birth (LE3). A shortening of more than 10% of the cervical length at 3-week interval is associated with an increased risk of preterm birth (LE3). Systematic detection of fetal fibronectin is not recommended in

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

    contingency tables. The pattern of fetal mortality rate was analyzed through direct standardization. To study the risk of late fetal mortality, adjusted by age and prematurity, a Poisson regression model was used. Results: The rates of fertility and late fetal mortality increased in women aged more than 35 years, especially in women aged more than 45 years. The risk of late fetal mortality was 2.7 times higher in women aged 45 years and above (rate ratio, 2.7; 95%CI: 1.8-3, with an etiological fraction of exposure of 69% (95%CI: 55.2-78.6. The prevalence rate of prematurity and low birth weight was three times higher in this age group, with a prevalence rate of prematurity of 2.9 (95%CI: 2.7-3.1 and of low birth weight of 3.1 (95%CI: 2.9-3.3. Conclusions: The high risk found in women aged more than 45 years is explained by the increase in the proportion of pregnancies within this age group during the period analyzed. Further studies in perinatal epidemiology that analyze the impact of assisted reproduction techniques in pregnancies in older women are required, as well as a national registry of assisted reproduction techniques.

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

Treatments of preterm birth are becoming more and more,but the medication treatment effect is still controversial. Premature death due to medical intervention is still difficult to avoid, therefore scholars in China and abroad are turning their attention to early prediction of preterm labor. Here is to make a review on the prediction indexes and treatments of a certain clinical significance.

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

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

    In this retrospective study, the relationship between demographic characteristics, past medical history, general lifestyle habits and susceptibility of premature ovarian failure (POF) in Han Chinese population was investigated. Five hundred and fifty-three patients with POF and 400 women with normal ovarian function were recruited. A questionnaire was designed to gather information from responders. Logistic regression was carried out to calculate odds ratios (OR), 95% confidence intervals (95% CI) and P-values. History of pelvic surgery, mumps, having relatives with menstrual abnormalities and exposure to chemical agents were significantly associated with increased risk of POF (OR 5.53 [2.15 to 14.23]; 3.26 [2.38 to 4.47]; 28.12 [8.84 to 89.46]; 4.47 [2.09 to 9.58]). Vegetarian diet, tea and mineral water consumption reduced the risk of POF (OR 0.27 [0.19 to 0.37]; 0.04 [0.03 to 0.07]; 0.63 [0.47 to 0.85], respectively). Heredity, pelvic surgery, mumps and exposure to chemical agents were identified as risk factors for POF, whereas vegetarian diet, tea consumption and mineral water drinking were protective. Therefore, genetic consultation could help those women whose relatives manifested an early or premature menopause to avoid the consequences of possible premature ovarian function cessation. Avoidance of exposure to endocrine disrupters and flavonoids intake should be considered.

    Objective The general consensus has been that estrogen is invariably a risk factor for ischemic stroke (IS). We reviewed new observational studies that challenge this simple conclusion. Methods This was a review of observational studies of the association of premature or early menopause with stroke or IS published in English from 2006 through 2010. Results Three cohort studies showed an increased risk of all stroke in women who underwent bilateral oophorectomy compared with women who conserved their ovaries before age 50 years. The increased risk of stroke was reduced by hormonal therapy (HT) in one of the studies, suggesting that estrogen deprivation is involved in the association. Four additional observational studies showed an association of all stroke or IS with the early onset of menopause or with a shorter lifespan of ovarian activity. In three of the seven studies, the association was restricted to IS. Age at menopause was more important than type of menopause (natural vs induced). Conclusions The findings from seven recent observational studies challenge the consensus that estrogen is invariably a risk factor for IS and can be reconciled by a unifying timing hypothesis. We hypothesize that estrogen is protective for IS before age 50 years and may become a risk factor for IS after age 50 years or, possibly, after age 60 years. These findings are relevant to women who experienced premature or early menopause, or to women considering prophylactic bilateral oophorectomy before the onset of natural menopause. PMID:21993082

    Preterm birth (PTB) is the leading cause of neonatal mortality, and surviving infants are at increased risk for lifelong disabilities. Intrauterine inflammation is an etiological factor that drives PTB, and oxidative stress is associated with PTB. Nuclear erythroid 2-related factor 2 (Nrf2) is a redox-sensitive transcription factor that is the key regulator of the response to oxidative and inflammatory stress. Here, we used the established mouse model of intrauterine inflammation-induced PTB to determine whether Nrf2 is a modifier of susceptibility to PTB and prematurity-related morbidity and mortality in the offspring. We determined that Nr2-deficient (Nrf2−/−) mice exhibited a greater sensitivity to intrauterine inflammation, as indicated by decreased time to delivery, reduced birthweight, and 100% mortality. Placentas from preterm Nrf2−/− mice showed elevated levels of markers of inflammation, oxidative stress, and cell death, and transcriptomic analysis identified numerous key signaling pathways that were differentially expressed between wild-type (WT) and Nrf2−/− mice in both preterm and control samples. Thus, Nrf2 could be a critical factor for gene-environment interactions that may determine susceptibility to PTB. Further studies are needed to determine if Nrf2 is a viable therapeutic target in women who are at risk for PTB and associated complications in the affected offspring. PMID:28071748

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

    Full Text Available Introduction. Retinopathy of prematurity (ROP is a multifactorial disease that occurs most frequently in very small and very sick preterm infants, and it has been identified as the major cause of childhood blindness. Objective. The aim of this study was to evaluate ROP incidence and risk factors associated with varying degrees of illness. Methods. The study was conducted at the Centre for Neonatology, Paediatric Clinic of the Clinical Centre Kragujevac, Serbia, in the period from June 2006 to December 2008. Ophthalmologic screening was performed in all children with body weight lower than 2000 g or gestational age lower than 36 weeks. We analyzed eighteen postnatal and six perinatal risk factors and the group correlations for each of the risk factors. Results. Out of 317 children that were screened, 56 (17.7% developed a mild form of ROP, while 68 (21.5% developed a severe form. Univariate analysis revealed a large number of statistically significant risk factors for the development of ROP, especially the severe form. Multivariate logistical analysis further separated two independent risk factors: small birth weight (p=0.001 and damage of central nervous system (p=0.01. Independent risk factors for transition from mild to severe forms of ROP were identified as: small birth weight (p=0.05 and perinatal risk factors (p=0.02. Conclusion. Small birth weight and central nervous system damage were risk factors for the development of ROP, perinatal risk factors were identified as significant for transition from mild to severe form of ROP.

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

    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.

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

    Swimming during pregnancy is recommended. However, the use of swimming pools is also associated with infection by water-borne pathogens and exposure to water disinfection byproducts, which are 2 mechanisms that are suspected to increase risk for birth defects. Thus, we evaluated the relationship between maternal swimming pool use during early pregnancy and risk for select birth defects in offspring. Data were evaluated for nonsyndromic cases with 1 of 16 types of birth defects (n = 191-1829) and controls (n = 6826) from the National Birth Defects Prevention Study delivered during 2000-2006. Logistic regression analyses were conducted separately for each birth defect type. Separate analyses were conducted to assess any pool use (yes vs no) and frequent use (5 or more occasions in 1 month) during the month before pregnancy through the third month of pregnancy. There was no significant positive association between any or frequent pool use and any of the types of birth defects, even after adjustment for several potential confounders (maternal race/ethnicity, age at delivery, education, body mass index, folic acid use, nulliparity, smoking, annual household income, surveillance center, and season of conception). Frequent pool use was significantly negatively associated with spina bifida (adjusted odds ratio, 0.68; 95% confidence interval, 0.47-0.99). Among offspring of women 20 years old or older, pool use was associated with gastroschisis (adjusted odds ratio, 1.3; 95% confidence interval, 1.0-1.8), although not significantly so. We observed little evidence suggesting teratogenic effects of swimming pool use. Because swimming is a common and suggested form of exercise during pregnancy, these results are reassuring.

    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.

    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 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.

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

    Although premature birth is associated with lags in language acquisition, it is unclear whether preterms exhibit an elevated risk for language impairment (LI). This study determined whether preterms, without frank cerebral damage, at 2;6 and 3;6 exhibited a higher rate of risk for LI as compared to full-terms, and also sought to identify predictors of risk. Sixty-four Italian very immature preterms were assessed longitudinally at 2;6 and 3;6; age-matched full-terms served as controls at 2;6 (n=22) and 3;6 (n=40). Each completed individualized assessments of cognition and language ability. At each time point, using cut-offs specific to each of the language measures, children were differentiated into two groups (at risk for LI, not at risk). The percentage of full-terms at risk for LI at 2;6 (9.1% to 13.6%) and 3;6 (7.5%) was consistent with prior estimates of LI at these ages. The percentage of preterms at risk for LI at 2;6 (16.1% to 24.1%) and 3;6 (34.4%) was higher at both ages and statistically significant at 3;6 (difference=26.8%, 95% CI=12.3% to 41.4%). The best model predicting risk status at 3;6 was preterms' mean length of utterance (MLU) at 2;6, (sensitivity 72.73%, specificity 85%) when adjusting for maternal education. Preterms exhibit a heightened risk for LI in the preschool years, since about one in four preterms at 2;6 and one in three preterms at 3;6 experiences significant lags in language acquisition. Findings argue the importance of early identification of language difficulties among preterms coupled with implementation of systematic language-focused interventions for these youngsters.

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

    Full Text Available 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.

    To determine the measures to prevent spontaneous preterm birth (excluding preterm premature rupture of membranes)and its consequences. The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. In France, premature birth concerns 60,000 neonates every year (7.4 %), half of them are delivered after spontaneous onset of labor. Among preventable risk factors of spontaneous prematurity, only cessation of smoking is associated to a decrease of prematurity (level of evidence [LE] 1). This is therefore recommended (grade A). Routine screening and treatment of vaginal bacteriosis in general population is not recommended (grade A). Asymptomatic women with single pregnancy without history of preterm delivery and a short cervix between 16 and 24 weeks is the only population in which vaginal progesterone is recommended (grade B). A history-indicated cerclage is not recommended in case of only past history of conisation (grade C), uterine malformation (Professional consensus), isolated history of pretem delivery (grade B) or twin pregnancies in primary (grade B) or secondary (grade C) prevention of preterm birth. A history-indicated cerclage is recommended for single pregnancy with a history of at least 3 late miscarriages or preterm deliveries (grade A).). In case of past history of a single pregnancy delivery before 34 weeks gestation (WG), ultrasound cervical length screening is recommended between 16 and 22 WG in order to propose a cerclage in case of lengthpremature rupture of membranes. Maintenance tocolysis is not recomended (grade B). Antenatal corticosteroid administration is recommended to every woman at risk of preterm delivery before 34 weeks of gestation (grade A). After 34 weeks, evidences are not consistent enough to recommend systematic antenatal corticosteroid treatment (grade B), however, a course might be indicated in the clinical situations associated with the

    Preeclampsia (PE), small for gestational age (SGA), and spontaneous preterm birth (PTB) each may be complications of impaired placental function in pregnancy. Although their exact pathogenesis is still unknown, certain infectious agents seem to play a role. Helicobacter pylori (H. pylori) colonization has been associated with increased risk for PE. Our aim was to assess the association between H. pylori colonization and PE, SGA, and PTB. We measured IgG anti-H. pylori and CagA antibodies in serum of pregnant women (median 20.5 weeks, range 16.5-29.4) who participated in a population-based prospective cohort study. Delivery and medical records were assessed. Information on demographics, education, and maternal risk factors was collected by questionnaire. We used multivariate logistic regression analyses to assess associations between H. pylori colonization and PE, SGA, and PTB. In total, 6348 pregnant women were assessed. H. pylori positivity was found in 2915 (46%) women, of whom 1023 (35%) also were CagA-positive. Pregnancy was complicated by PE, SGA, or PTB in 927 (15%) women. H. pylori colonization was associated with PE (aOR 1.51; 95%CI 1.03-2.25). Differentiation according to CagA status revealed the same risk. H. pylori was positively related with SGA, mainly explained by CagA-positive strains (aOR 1.34; 1.04-1.71). No association was observed between H. pylori and PTB. Our data suggest that H. pylori colonization may be a risk factor for PE and SGA. If these associations are confirmed by future studies and shown to be causal, H. pylori eradication may reduce related perinatal morbidity and mortality. © 2016 John Wiley & Sons Ltd.

    OBJECTIVE: To assess risk factors of otitis media (OM) in six-months-old children. METHOD: The sample consisted of 69,105 mothers and their children from the Danish National Birth Cohort. The women were interviewed twice during pregnancy and again 6 months after birth. The outcome "one or more...... associated with a risk of OM. When a Bonferroni correction was introduced, gender, prematurity, parity, maternal age, maternal self-estimated health, taking penicillin during pregnancy, and terminating breastfeeding before age six months, was associated with a risk of early OM. The adjusted ORs of OM...... less than 6 months, had an increased OR of 1.42 (95% CI 1.28-1.58) compared to children being breastfeed beyond 6 months. CONCLUSION: These findings indicate that prenatal factors are of less importance regarding early OM before the age of six months. Postnatal risk factors seem to pose the main risk...

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

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

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

    Background Retinopathy of prematurity (ROP) is a blinding morbidity of preterm infants. Our current screening criteria have remained unchanged since their inception and lack the ability to identify those at greatest risk. Objectives We sought to comprehensively analyze numerous proposed maternal, infant, and environmental ROP risk variables in a robustly phenotyped population using logistic regression to determine the most predictive model for ROP development and severity. We further sought to determine the statistical interaction between significant ROP risk variables, which has not previously been done in the field of ROP. We hypothesize that our comprehensive analysis will allow for better identification of risk variables that independently correlate with ROP disease. Going forward, this may allow for improved infant risk stratification along a time continuum from prenatal to postnatal development, making prevention more feasible. Methods We performed a retrospective cohort analysis of preterm infants referred for ROP screening in one neonatal intensive care unit from 2010–2015. The primary outcome measure was presence of ROP. Secondary outcome measures were ROP requiring treatment and severe ROP not clearly meeting current treatment criteria. Univariate, stepwise regression and statistical interaction analyses of 57 proposed ROP risk variables was performed to identify variables which were significantly associated with each outcome measure. Results We identified 457 infants meeting our inclusion criteria. Within this cohort, numerous factors showed a significant individual association with our ROP outcome measures; however, stepwise regression analysis found the most predictive model for overall ROP risk included estimated gestational age, birth weight, the need for any surgery, and maternal magnesium prophylaxis. The corresponding Area Under the Curve (AUC) for this model was 0.8641, while the traditional model of gestational age and birth weight predicted

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

    Full Text Available BACKGROUND: Risk factors for congenital cryptorchidism were investigated in a prospective birth cohort study in Denmark and Finland from 1997 to 2001. METHODOLOGY AND PRINCIPAL FINDINGS: In total, 2,496 boys were examined for cryptorchidism at birth (cryptorchid/healthy: 128/2,368 and three months old (33/2,215. Information on risk factors was obtained antenatally (questionnaire/interview or at birth from birth records. Use of nicotine substitutes during pregnancy (n = 40 and infertility treatment by intrauterine insemination (n = 49 were associated with an increased risk for cryptorchidism, adjusted odds ratio (95% confidence interval (OR (95%CI 3.04 (95%CI 1.00-9.27 and 3.01 (95%CI 1.27-7.15, respectively. No association was seen for mothers (n = 79 who had infertility treatment in form of intracytoplasmic sperm injection (ICSI or in vitro fertilization (IVF treatment (OR 0.71 95%CI 0.21-2.38. In total, 728 (29% reported to have smoked during pregnancy, however, no increased risk among maternal smokers was found. Furthermore, we found statistically significant associations between cryptorchidism and low birth weight, prematurity, being small for gestational age, substantial vaginal bleeding, and breech presentation, which are in accordance with other studies. CONCLUSIONS AND SIGNIFICANCE: Our study revealed two novel risk factors for cryptorchidism: intrauterine insemination and the use of nicotine substitutes in pregnancy. This suggests that cryptorchidism may not only be associated to genetic factors, but also to maternal lifestyle and exposure.

Material and Methods. Under supervision there were 139 pregnant women with application ART. 202 children (51 twins were born and 5 triplet babies, from them 83 premature infants born from multiple induced pregnancy have been analyzed. Results. The newborns examined by method ART, were distributed as follows: 22-28 weeks — 19 children; 29-32 weeks — 23; 33-36 weeks — 41. Asphyxia at birth was marked at all premature infants. Respiratory insufficiency at birth is revealed in 87,3% of cases. The most frequent pathologies in premature infants are revealed: neurologic infringements and bronchopulmonary pathology occured at all children, developmental anomaly — 33, 8%, retinopathies in premature infants — 26,5%. The mortality causes include: extreme immaturity, cerebral leukomalacia, IVN 3 degrees. Conclusion. The risk factors, premature birth at application of methods ART are revealed: aged primiparas, pharmacological influence, absence of physiological conditions of prenatal development; multifetation. The high percent of birth of children with ELBW and ULBW is revealed. RDCN with further BPD development, retinopathies in premature infants and CNS defeat is more often occured.

  5. Cervical mucus properties stratify risk for preterm birth.

    Directory of Open Access Journals (Sweden)

    Agatha S Critchfield

    Full Text Available BACKGROUND: Ascending infection from the colonized vagina to the normally sterile intrauterine cavity is a well-documented cause of preterm birth. The primary physical barrier to microbial ascension is the cervical canal, which is filled with a dense and protective mucus plug. Despite its central role in separating the vaginal from the intrauterine tract, the barrier properties of cervical mucus have not been studied in preterm birth. METHODS AND FINDINGS: To study the protective function of the cervical mucus in preterm birth we performed a pilot case-control study to measure the viscoelasticity and permeability properties of mucus obtained from pregnant women at high-risk and low-risk for preterm birth. Using extensional and shear rheology we found that cervical mucus from women at high-risk for preterm birth was more extensible and forms significantly weaker gels compared to cervical mucus from women at low-risk of preterm birth. Moreover, permeability measurements using fluorescent microbeads show that high-risk mucus was more permeable compared with low-risk mucus. CONCLUSIONS: Our findings suggest that critical biophysical barrier properties of cervical mucus in women at high-risk for preterm birth are compromised compared to women with healthy pregnancy. We hypothesize that impaired barrier properties of cervical mucus could contribute to increased rates of intrauterine infection seen in women with preterm birth. We furthermore suggest that a robust association of spinnbarkeit and preterm birth could be an effectively exploited biomarker for preterm birth prediction.

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

  7. 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.

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

METHODS: Neonates with gestational age <37wks and/ or birth weight ≤ 2500gms born over one year period were examined by indirect ophthalmoscopy between 2 to 4 weeks after birth, and followed up till retinal vascularization was complete. Maternal and neonatal risk factors were noted and data analyzed by statistical package SPSS-15. RESULTS: 100 babies were thus examined. The overall incidence of retinopathy of prematurity was 40%, 22%in babies’ ≤34wks of gestation and 52% in babies with a birth weight1500-2000g. Majority were in stage 2. Gestational age (<32weeks, Birth weight (<1500g, RDS, surfactant therapy, PDA were found to be risk factors. CONCLUSION: Meticulous fundus examination with indirect ophthalmoscopy in all preterm babies with gestational age<37weeks and birth weight ≤ 2500gms is essential noninvasive method for early detection of ROP and its progression. Screening should be intensified in the presence of factors like RDS, oxygen administration and presence of PDA

    Full Text Available Research question: What is the extent of low weight babies born in hospitals and its association with some maternal factors? Objectives: 1. To find an overall prevalence of low birth weight babies amongst hospital births in Meerut city. 2. To identify and quantify the effects of some risk factors for low birth weight. Setting: District women Hospital of Meerut city of western U.P. Study Design: Hospital based matched case-control study. Sample size: 491 low birth weight babies as ‘cases’ and an equal number of babies of normal birth weight in ‘control’ group matched for maternal age, sex of baby, birth order and institution of delivery. Study variables: Socio-economic Status: maternal biological factors including obstetric history: antenatal factors: nutritional factors: history of abortion: toxaemia of pregnancy etc. Results: Overall proportion of low birth weight babies was found to be 21.8% amongst hospital live births and 30.9% born to mothers aged below 30 years of age. Low maternal weight, under nutrition, lack of antenatal care, short inter-pregnancy interval, toxacmia of pregnancy were independent factors increasing the risk of low birth weight significantly. Conclusions: The study suggested that a substantial proportion of low birth weight babies can be averted by improving maternal nutritional status including anemic condition, birth spacing and proper antenatal care.

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

    Full Text Available Abstract Background Assisted reproduction (ART contributes to world-wide increases of twin pregnancies, in turn raising prematurity risks. Whether characteristics of ART cycles, resulting in twin gestations, can predict prematurity risks was the subject of this study. Methods One-hundred-and-six women, ages 20 to 39 years, with consecutive dichorionic-diamniotic (DC/DA twin gestations were retrospectively investigated. All pregnancies investigated followed fresh ART cycles, with use of autologous gamets, and were delivered at a university-based high-risk, maternal-fetal medicine unit. Only premature deliveries (i.e., <37.0 weeks gestational age, with viable neonate(s of ≥ 500 grams, were considered for analysis. Results After 1.8 +/- 1.2 ART cycles, 11.0 +/- 5.4 oocytes were retrieved and 2.4 +/- 0.9 embryos transferred in 106 women aged 31.6 +/- 4.2 years. Indications for ART treatment were male factor in 51.9%, female infertility in 27.4% and combined infertility in 20.8%. Though maternal age significantly influenced prematurity risk (p < 0.05, paternal age, maternal body mass index, indications for fertility treatment, number of previous ART attempts, oocytes retrieved or embryos transferred, as well as stimulation protocols and previous ART pregnancies, were not associated with gestational duration in twin pregnancies. Summary Except for female age, baseline and ART cycle characteristics do not allow for prediction of prematurity risk in dichorionic twin gestations after assisted reproduction.

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

    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.

    2010-04-01

    Full Text Available Adult onset glioma is a rare cancer which occurs more frequently in Caucasians than African Americans, and in men than women. The etiology of this disease is largely unknown. Exposure to ionizing radiation is the only well established environmental risk factor, and this factor explains only a small percentage of cases. Several recent studies have reported an association between season of birth and glioma risk. This paper reviews the plausibility of evidence focusing on the seasonal interrelation of farming, allergies, viruses, vitamin D, diet, birth weight, and handedness. To date, a convincing explanation for the occurrence of adult gliomas decades after a seasonal exposure at birth remains elusive.

    periods. Data were analyzed using descriptive statistics. Student's t test was used to compare means for birth weight and gestational age between mothers who had suffered domestic violence during the current pregnancy and those who had not. Logistic regression analysis was employed to identify factors associated with low birth weight or prematurity. RESULTS: During the prenatal and postnatal periods, 89.1% (n = 1,229 of the pregnant women were followed up, 10.9% being lost to follow-up, basically due to changes of address. Mean birth weight was 3,233 g; mean gestational age was 38.56 weeks. A total of 13.8% of the infants had low birth weight or were premature. Conditions associated with risk of low birth weight or prematurity were: mothers who had previously given birth prematurely (p < 0.005, who smoked (p < 0.001, who delivered by caesarian (p < 0.001 and whose partners had a low educational level (p < 0.008.

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

    This article reviews the role of infection in spontaneous premature parturition, the pathways of ascending intrauterine infection, microbiology, and the frequency of intra-amniotic infection in obstetrical complications leading to premature delivery. The evidence that infection is causally linked to premature birth is critically examined, as is the relationship between urogenital tract infection/colonization with microorganisms and the risk of preterm birth. The effect of antibiotic administration in perinatal outcome in patients with preterm labor and intact membranes, preterm premature rupture of membranes, asymptomatic bacteriuria, Group B streptococcus and genital mycoplasmas of the lower genital tract, and bacterial vaginosis are critically examined.

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

    Directory of Open Access Journals (Sweden)

    Mark F Cotton

    2015-12-01

    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

    To study the biologic effect of paracetamol, an inhibitor of prostaglandin synthase, on early closure of ductus arteriosus, and to evaluate possible adverse effects associated with the drug. In a controlled, double-blind, phase I-II trial, very low gestational age (<32 weeks) infants requiring intensive care were randomly assigned to intravenous paracetamol or placebo (0.45% NaCl). A loading dose of 20 mg/kg was given within 24 hours of birth, followed by 7.5 mg/kg every 6 hours for 4 days. Daily cardiac ultrasound examinations of ductal calibers were performed before the first dose, and until 1 day after the last dose. The main outcome was a decrease in the ductal caliber without side effects. Of 63 screened infants, 48 were randomized: 23 were assigned to paracetamol and 25 to placebo. Before the intervention, their ductal calibers were similar. During the intervention, the ductus closed faster in the paracetamol group (hazard ratio 0.49, 95% CI 0.25-0.97, P = .016). The mean (95% CI) postnatal ages for ductal closure were 177 hours (31.1-324) for the paracetamol-treated vs 338 hours (118-557) for controls (P = .045). Paracetamol serum levels were within the therapeutic range, and no adverse effects were evident.

    Full Text Available Background: Traditional cardiovascular risk factors are strong predictors of an increased likelihood for premature CHD. Considering the benefits of risk factors᾿ management, it is imperative to find and treat them before looking for more unknown and weak risk factors. Objectives: Limited information is available about the demographic and historical characteristics of the patients with premature Coronary Heart Disease (CHD in IR Iran. The main objective of this study was to determine the prevalence of the traditional risk factors in these patients. Also, the researchers hypothesized that there are insufficient risk assessment and preventive intervention methods for the asymptomatic adult population. Methods: This study was conducted on 125 patients with premature CHD (age<50 years who were admitted in two academic hospitals with acute coronary syndromes. The patients were accepted since they had a definite CHD on the basis of acute myocardial infarction (elevated cardiac enzymes or documented CAD in coronary angiography. Results: The mean age of the study population was 42.50±5.65 (26 to 49 years. Among the patients,92 (73.6% were male, 113 (90.4% were married, 58 (46.4% were smokers,19 (15.2% were opium users, 97 (77.6% had dyslipidemia, 44 (35.2% had hypertension, and 33 (26.4% had diabetes mellitus. In addition, family history was presented in 54 patients (43.2%. Conclusions: Premature Coronary Heart Disease is a public health problem. However, there is lack of effective and intensive treatments of well-defined traditional risk factors and prevention methods for the majority of the patients experiencing premature CHD. In sum, there is still plenty of room for improvement of risk management in IR Iran.

    The aim of the study is to investigate the association between gestational age, birth size, and the long-term risk of maternal diabetes. We conducted a nation-wide prospective follow-up study of the cohort of all Danish women with a singleton delivery in 1982/1983 (index delivery) and no history of diabetes (n = 100,669). Registries were used to extract information on patients with a hospital or outpatient diagnosis of diabetes, subsequent deliveries, and death/emigration in the period from the index delivery until the end of 2006. The association between the maternal risk of diabetes and the index gestational age and index offspring birth size (birth weight adjusted for gestational age) was investigated by using Cox proportional hazards regression models stratified according to young (≤33 years) and old age (>33 years). During a median follow-up period of 24 years, 2,021 women (2.0 %) were diagnosed as having diabetes. The risk of maternal diabetes was positively associated with increasing index birth size and negatively associated with increasing duration of index gestation in both age strata. Among young women, the highest hazard ratios were found for the exposure category of large index offspring birth size (adjusted HR 9.0, 95 % CI 6.17-13.12) and a preterm delivery at 32-37 weeks (adjusted HR 2.22, 95 % CI 1.46-3.40). Offspring preterm birth and large size for gestational age at birth are associated with increased risk of maternal diabetes.

    To test the hypothesis that sleep disorder diagnosis would be associated with increased risk of preterm birth and to examine risk by gestational age, preterm birth type, and specific sleep disorder (insomnia, sleep apnea, movement disorder, and other). In this observational study, participants were from a cohort of nearly 3 million women in California between 2007 and 2012. Inclusion criteria were women with singleton neonates liveborn between 20 and 44 weeks of gestation without chromosomal abnormalities or major structural birth defects linked to a hospital discharge database maintained by the California Office of Statewide Health Planning and Development and without mental illness during pregnancy. Sleep disorder was defined based on International Classification of Diseases, 9th Revision, Clinical Modification diagnostic code (n=2,265). Propensity score matching was used to select a referent population at a one-to-one ratio. Odds of preterm birth were examined by gestational age (less than 34 weeks, 34-36 weeks, and less than 37 weeks of gestation) and type (spontaneous, indicated). Prevalence of preterm birth (before 37 weeks of gestation) was 10.9% in the referent group compared with 14.6% among women with a recorded sleep disorder diagnosis. Compared with the referent group, odds (95% CI, P value, percentage) of preterm birth were 1.3 (1.0-1.7, P=.023, 14.1%) for insomnia and 1.5 (1.2-1.8, Ppreterm birth type. Odds of preterm birth were not significantly increased for sleep-related movement disorders or other sleep disorders. Insomnia and sleep apnea were associated with significantly increased risk of preterm birth. Considering the high prevalence of sleep disorders during pregnancy and availability of evidence-based nonpharmacologic interventions, current findings suggest that screening for severe presentations would be prudent.

    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.

    There is ongoing controversy as to whether obesity confers risk for CAD independently of associated risk factors including diabetes mellitus. We have carried out a Mendelian randomization study using a genetic risk score (GRS) for body mass index (BMI) based on 35 risk alleles to investigate this question in a population of 5831 early onset CAD cases without diabetes mellitus and 3832 elderly healthy control subjects, all of strictly European ancestry, with adjustment for traditional risk factors (TRFs). We then estimated the genetic correlation between these BMI and CAD (rg) by relating the pairwise genetic similarity matrix to a phenotypic covariance matrix between these two traits. GRSBMI significantly (P=2.12 × 10(-12)) associated with CAD status in a multivariate model adjusted for TRFs, with a per allele odds ratio (OR) of 1.06 (95% CI 1.042-1.076). The addition of GRSBMI to TRFs explained 0.75% of CAD variance and yielded a continuous net recombination index of 16.54% (95% CI=11.82-21.26%, Pobesity and CAD. This analysis supports the hypothesis that obesity is a causal risk factor for CAD.

    As part of a study of thyroid function in premature babies, the iodine content of their mothers' breast milk, that of 32 formulas from different brands used in Spain, and that of 127 formulas used in other countries was determined. Breast milk contained more iodine--mean (SEM) 10 (1) microgram/dl--than most of the formulas, especially those for premature babies. Iodine intakes were therefore below the recommended daily amount (RDA) for newborns: babies of 27-30 weeks' gestational age took 3.1 (1.1) micrograms/day at 5 days of age and 29.8 (2.7) micrograms by 2 months of age. This problem is not exclusive to Spanish premature babies as the iodine content of many of the formulas on sale in other countries was also inadequate. It is concluded that preterm infants who are formula fed are at high risk of iodine deficiency.

    Full Text Available Background: To investigate the incidence and risk factors of retinopathy of prematurity (ROP in two Neonatal Intensive Care Units in North and South of China, respectively. Methods: We studied data concerning 472 infants with gestational age (GA ≤34 weeks or birth weight (BW ≤2000 g who were admitted to the Zhujiang Hospital of Southern Medical University and the Fourth Hospital of Shijiazhuang between January 1, 2011 and December 31, 2011. Clinical information about perinatal neonates was collected and was confirmed by reviewing medical charts. The incidence and severity of ROP were assessed in the screened population. Main outcome measures are the incidence and severity of ROP. The relationship of clinical risk factors and the development of ROP were analyzed. Results: The overall incidence of ROP was 12.7%, and the overall incidence of type 1 ROP was 2.3%; 9.4% of infants in Zhujiang Hospital had ROP compared to 15.0% infants in the Fourth Hospital of Shijiazhuang developed ROP, and the difference is statistically significant. ROP was significantly associated with GA (odds ratio [OR]: 0.77 [0.62-0.95], P = 0.015, BW (OR: 0.998 [0.996-0.999], P = 0.008, maternal supplemental oxygen administration before and during delivery (OR: 4.27 [1.21-15.10], P = 0.024 and preeclampsia (OR: 6.07 [1.73-21.36] P = 0.005. The risk factors for ROP are different in two hospitals. In Zhujiang Hospital, BW is the independent risk factors for ROP while GA, BW and preeclampsia in the Fourth Hospital in Shijiazhuang Conclusions: Retinopathy of prematurity incidence is different based on area. Incidence of ROP is still high in China. More efforts need to prevent ROP.

    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: 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.

    This study evaluated the prevalence of enamel defects and dental caries and their risk factors on primary and permanent dentitions of prematurely-born children and term children. Eighty children were examined, 40 born prematurely (G1) and 40 born term (G2), in the age group between 5 and 10 years. The demographic variables, medical history and oral health behaviors were recorded on a questionnaire. The teeth were examined for presence of deficiencies of the enamel and caries that were registered. The caries were registered, focusing on the indices dmft (decayed, missing, and filled primary teeth) and DMFT (decayed, missing, and filled permanent teeth). The results showed that 75% of the total sample had enamel defects. The logistic regression model showed that other risk factors such as per capita family income, educational level, dietary and hygiene habits, fluoride exposure, trauma, and diseases had no correlation with enamel defects and caries. A smaller value of total DMFT (0.95) was found in the group of premature children in comparison to the term children (2.07) p = 0.0164. There was no difference concerning the permanent dentition between the two groups (p = 0.9926). One concludes that prematurity can't be a predisposing factor for the presence of dental caries.

  17. Human milk for the premature infant

    Underwood, Mark A.

    2012-01-01

    Synopsis Premature infants are a heterogeneous group with widely differing needs for nutrition and immune protection with risk of growth failure, developmental delays, necrotizing enterocolitis, and late-onset sepsis increasing with decreasing gestational age and birth weight. Human milk from women delivering prematurely has more protein and higher levels of many bioactive molecules compared to milk from women delivering at term. Human milk must be fortified for small premature infants to achieve adequate growth. Mother’s own milk improves growth and neurodevelopment and decreases the risk of necrotizing enterocolitis and late-onset sepsis and should therefore be the primary enteral diet of premature infants. Donor milk is a valuable resource for premature infants whose mothers are unable to provide an adequate supply of milk, but presents significant challenges including the need for pasteurization, nutritional and biochemical deficiencies and a limited supply.

  1. Prenatal Stress, Prematurity, and Asthma.

    Science.gov (United States)

    Medsker, Brock; Forno, Erick; Simhan, Hyagriv; Celedón, Juan C

    2015-12-01

    Asthma is the most common chronic disease of childhood, affecting millions of children in the United States and worldwide. Prematurity is a risk factor for asthma, and certain ethnic or racial minorities such as Puerto Ricans and non-Hispanic blacks are disproportionately affected by both prematurity and asthma. In this review, we examine current evidence to support maternal psychosocial stress as a putative link between prematurity and asthma, while also focusing on disruption of the hypothalamic-pituitary-adrenal (HPA) axis and immune responses as potential underlying mechanisms for stress-induced "premature asthma." Prenatal stress may cause not only abnormalities in the HPA axis but also epigenetic changes in the fetal glucocorticoid receptor gene (NR3C1), leading to impaired glucocorticoid metabolism. Moreover, maternal stress can alter fetal cytokine balance, favoring TH2 (allergic) immune responses characteristic of atopic asthma: interleukin 6 (IL-6), which has been associated with premature labor, can promote TH2 responses by stimulating production of IL-4 and IL-13. Given a link among stress, prematurity, and asthma, future research should include birth cohorts aimed at confirming and better characterizing "premature asthma." If confirmed, clinical trials of prenatal maternal stress reduction would be warranted to reduce the burden of these common comorbidities. While awaiting the results of such studies, sound policies to prevent domestic and community violence (eg, from firearms) are justified, not only by public safety but also by growing evidence of detrimental effects of violence-induced stress on psychiatric and somatic health.

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

    Most testicular germ cell tumors originate from carcinoma in situ cells in fetal life, possibly related to sex hormone imbalances in early pregnancy. Previous studies of association between gestational age at birth and testicular cancer have yielded discrepant results and have not examined extreme preterm birth. Our objective was to determine whether low gestational age at birth is independently associated with testicular cancer in later life. We conducted a national cohort study of 354,860 men born in Sweden in 1973–1979, including 19,214 born preterm (gestational age testicular cancer incidence through 2008. A total of 767 testicular cancers (296 seminomas and 471 nonseminomatous germ cell tumors) were identified in 11.2 million person-years of follow-up. Extreme preterm birth was associated with an increased risk of testicular cancer (hazard ratio 3.95; 95% CI, 1.67–9.34) after adjusting for other perinatal factors, family history of testicular cancer, and cryptorchidism. Only five cases (three seminomas and two nonseminomas) occurred among men born extremely preterm, limiting the precision of risk estimates. No association was found between later preterm birth, post-term birth, or low or high fetal growth and testicular cancer. These findings suggest that extreme but not later preterm birth may be independently associated with testicular cancer in later life. They are based on a small number of cases and will need confirmation in other large cohorts. Elucidation of the key prenatal etiologic factors may potentially lead to preventive interventions in early life. PMID:22314417

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

    The supply of long-chain polyunsaturated fatty acids via the placenta is interrupted in premature infants, making them exclusively dependent on breast milk, which varies in fatty acid (FA) concentrations depending on the mother's diet. To in a longitudinal study explore the relation between FA status in mothers and infants from an unselected cohort of prematures, not requiring intensive care. Breast milk and mothers' and infants' plasma phospholipid FA concentrations from birth to 44 weeks of gestational age were analysed and compared with mothers' food intake, assessed using a 3-day diary. Fatty acids were analysed by capillary gas-liquid chromatography. The energy intake was low in 75% of mothers, and 90% had low intake of essential FAs (EFAs). Dietary linoleic acid (LA, 18:2w6), but not w3 FAs, correlated to concentrations in breast milk. Infants' plasma and breast milk correlated for arachidonic (AA, 20:4w6), eicosapentaenoic (EPA, 20:5w3) and docosahexaenoic (DHA, 22:6w3) acids. A high concentration of mead acid (20:3w9) in the infants at birth correlated negatively to the concentrations of LA, AA and w3 FAs. Infants of mothers who stopped breastfeeding during the study period showed decreased DHA concentrations and increased w6/w3 ratios, with the opposite FA pattern seen in the mothers' plasma. Although dietary w3 FAs were insufficient in an unselected cohort of mothers of premature infants, breastfeeding resulted in increased levels of DHA in the premature infants at the expense of the mothers, suggesting a general need to increase dietary w3 FAs during pregnancy and lactation.

    Premature birth is a significant global problem and the leading cause of newborn deaths. Tobacco smoking has been associated with premature birth for over 50 years. The mechanisms through which smoking exerts its effects on pregnancy outcomes remain unclear. In this review, we discuss rates of prematurity and smoking in pregnancy, the evidence of a causal relationship between tobacco and preterm birth, and proposed biochemical pathways through which the interaction is mediated. The suggested mechanisms include nicotine-induced vasoconstriction, carbon monoxide-induced fetal hypoxia, cadmium disruption of calcium signaling, altered steroid hormone production, disruption of prostaglandin synthesis, and changed responses to oxytocin. The relative importance of each of these pathways is yet to be ascertained. Further research is necessary to explore the mechanisms through which smoking exerts its effect on gestational length and the process of parturition. Moreover, the risks of nicotine replacement in pregnancy should be investigated further. © The Author(s) 2014.

    Full Text Available Context: Recent advances in neonatology have influenced the incidence and severity of ROP in a dichotomous fashion. Aims: To determine the incidence of ROP and to analyse its risk factors. Settings and Design: Prospective clinical case series. Materials and Methods: 282 preterm infants with birthweight 32 weeks, with birthweight between 1500-2000 g, who were at risk for ROP were selected. Weight gain proportion was measured as weight at 6 weeks minus birthweight divided by birthweight. Statistical Analysis: Univariate and multivariate logistic regression. Results: Incidence of any ROP was 21.6% while severe ROP was 6.7%. Prenatal factors like multiple gestation (P = 0.510 and antenatal steroids (P = 0.104 were not significantly associated with ROP. On multivariate analysis, postnatal factors like weight at birth < 1250 g (P = 0.01 and gestational age between 31-32 weeks (P = 0.02 were independent risk factors for any ROP, while intraventricular hemorrhage (P = 0.03 was the only independent risk factor for severe ROP. Mean birthweight of infants with severe ROP was 1056 μ 207 g (P = 0.004, which was significantly low. After logistic regression, the mean weight gain proportion at 6 weeks, of those neonates with severe ROP was 30%. Conclusions: Low birthweight and prematurity were the most important risk factors for developing any ROP, while intraventricular hemorrhage was the independent risk factor for developing severe ROP. The mean postnatal weight gain at 6 weeks was not statistically significant in neonates with severe ROP.

    This study examined the effects of prematurity, cumulative medical risk, and proximal and distal social forces on individual differences in the activity of the hypothalamic-pituitary-adrenal (HPA) axis in young adulthood. A prospective sample of 149 infants born healthy preterm (PT; n = 22), sick PT ( n = 93, medical illness, neurological illness, small for gestational age), and full term ( n = 34) was recruited from a Level III neonatal intensive care unit in southern New England between 1985 and 1989 and followed to age 23 years. Cumulative medical risk was indexed across seven assessment waves (spanning 17 years) using medical and neurological health status at birth, toddlerhood (ages 18 and 30 months), childhood (ages 4 and 8 years), and adolescence (ages 12 and 17 years). Distal risk included socioeconomic status (SES) at birth. Proximal social factors were indexed from assessments of the home environment and measures of child vulnerability and maternal self-esteem, involvement, and control style from birth, 4 years, 8 years, and 12 years. At age 23 years, five saliva samples were collected upon awakening, 45 min after waking, 4 hr after waking, 8 hr after waking, and bedtime (later assayed for cortisol). Results reveal effects of cumulative medical risk on the diurnal pattern of HPA axis activity, with moderating effects of SES and proximal social factors. Findings are discussed in terms of implications for contemporary theories related to developmental sensitivity and susceptibility to context and the developmental origins of health and disease theory.

    Full Text Available Introduction: Preterm birth is the most important cause of neonatal mortality and morbidity. It is a multifactorial disease with different etiologies, including genetic factors. Genetic variability is represented by single nucleotide polymorphisms (SNPs in genes of proteins involved in the contractile activity. We determine the association between SNP 12109G> A in REN associated with preterm birth and premature rupture of membrane. Materials and methods: A study of cases (N=112, 22–36 weeks of gestation; mean: 31, 95% confidence interval 30.7–32.2 and controls (N=66; 38–40 weeks of gestation from the last menstrual period; mean: 39.8, 95% confidence interval 38.9–39.4 was performed. Genomic DNA was isolated in all patients from peripheral blood. The SNP 12109G> A (Mbo I in REN was typified by PCR-restriction fragment length polymorphism. Results: A significant difference in the case group for the SNP 12109G>A was observed. The A allele was increased in women with preterm birth (81% cases vs. 15% control, p A has odds ratio 6.62 (95% confidence interval 3.14–14.15, which means a high risk of preterm birth/premature rupture of membrane in presence of allele A, both in homozygotes and in heterozygotes. Conclusion: Allelic frequency of A of SNP 12109G>A was higher in women with preterm birth than in women with normal vaginal delivery and could be considered a risk factor.

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

    , and congenital malformations. Neonatal sepsis occurs in about 5% of live births following premature rupture, but the rate triples after 24 hours, especially in premature infants. The rate of neonatal asphyxia also increases considerable after 24 hours. Congenital malformations, prolapse of the cord, and pelvic presentation are positively associated with premature rupture of membranes. If the decision is made to interrupt the pregnancy, it should be done between 12-24 hours after rupture because the risks of infection and respiratory difficulty are most balanced at that point. Vaginal deliveries should be preferred only if conditions are favorable for a prompt delivery. The gestational age, presence of infection, obstetric condition of the mother, and indication for hysterectomy are the most important points to consider i management of premature rupture.

  7. The development of parents-infant relationship in high-risk pregnancies and preterm birth

    Full Text Available The theory of human attachment, developed in 1951 by John Bowlby, has been widely applied across psychological, medical and social disciplines, especially in the context of developmental psychology; more recently it has been studied in the obstetric and neonatal fields. Numerous studies suggest that attachment patterns have an impact on the social, cognitive and emotional development of the off-spring, and are also believed to influence the individual’s psychosocial trajectories across the lifespan. Starting from empirical study of attachment, the psychological analysis of the experience of pregnancy allowed to introduce the concept of prenatal attachment, considered as the earlier internalized representation of the fetus that both parents acquire and elaborate during pregnancy. Recent studies have attempted to investigate how prenatal attachment develops in conditions of hazard, as for example in women hospitalized for a high-risk pregnancy or preterm birth. Literature showed that these clinical conditions may represent risk factors that, along with psychological distress and lack of familiar and social support, may adversely affect the mother-child relationship, with consequences on the psycosocial development of the off-spring. During pregnancy, medical team should assess mothers’ distress and attachment, perform procedures to positively develop attachment, and direct parents with low attachment scores to receive a professional, specific counseling. In the premature birth context, it is important to closely support mother-infant contact and to decrease maternal stress in every possible way during hospitalization and after discharge. Promotion of psychological wellbeing and attachment during pregnancy and after birth may serve as a crucial opportunity of improving maternal health practices, perinatal health and neonatal outcomes. Proceedings of the 10th International Workshop on Neonatology · Cagliari (Italy · October 22nd-25th, 2014

  8. The case of late preterm birth: sliding forwards the critical window for cognitive outcome risk

    Many survivors of preterm birth experience neurodevelopmental disabilities, such as cerebral palsy, visual and hearing problems. However, even in the absence of major neurological complications, premature babies show significant neuropsychological and behavioural deficits during childhood and beyond. While the clinical tools routinely used to assess neurocognitive development in those infants have been useful in detecting major clinical complications in early infancy, they have not been equally sensitive in identifying subtle cognitive impairments emerging during childhood. These methodological concerns become even more relevant when considering the case of late preterm children (born between 34 and 36 gestational weeks). Although these children have been traditionally considered as having similar risks for developmental problems as neonates born at term, a recent line of research has provided growing evidence that even late preterm children display altered structural and functional brain maturation, with potential life-long implications for neurocognitive functioning. A recent study by Heinonen put forward the hypothesis that environmental factors, in this case educational attainment, could moderate the association between late preterm birth (LPT) and neuropsychological impairments commonly associated with aging. In this paper we bring together clinical literature and recent neuroimaging evidence in order to provide two different but complementary approaches for a better understanding of the “nature-nurture” interplay underlying the lifespan neurocognitive development of preterm babies.

    To investigate whether single nucleotide polymorphisms (SNPs) in genes encoding the Toll-like receptor (TLR) signaling pathway modulate susceptibility to preterm birth (PTB). Prospective case-control study examining the contribution of nine TLR SNPs to PTB (<37 weeks) and PTB <32 weeks. Genotyping was done on neonatal blood using a multiplexed single-base extension assay. Chi-square test, Fischer's exact test and classification trees were used for data analysis. Preterm infants (n=177) were more likely to be African American (P=0.02), and were more likely to be born to mothers who smoked (P=0.007), had pregnancy-induced hypertension (PIH; P=0.002) and placental abruption (P=0.0004) when compared with term infants (n=146). The TLR2, TLR4, TLR5, TLR9, nuclear factor-kappa B1 (NFκB1), NFκBIA and IRAK1 variants were not associated with PTB whereas the TIR domain receptor-associated protein (TIRAP) variant was more prevalent in term infants when compared with preterm infants born <32 weeks (P=0.004). PTB <32 weeks was more prevalent in infants without the TIRAP variant whose mothers had PIH and did not smoke (P=0.001). Presence of the TIRAP variant protected against PTB <32 weeks (P=0.015) in Caucasian infants. In our study, a TLR pathway adapter variant (TIRAP (rs8177374)) protected against PTB<32 weeks, supporting our hypothesis that genetic variation in the innate immune signaling pathway contributes to altered risk of PTB.

    To investigate the Work Ability Index (WAI) as tool for identifying workers at risk of premature work exit in terms of disability pension, unemployment, or early retirement. Prospective cohort study of 11,537 male construction workers (mean age 45.5 years), who completed the WAI at baseline and reported their work status (employed, unemployed, disability pension, or retired) after mean 2.3 years of follow-up. Associations between WAI scores and work status were investigated by multinomial logistic regression analysis. The ability of the WAI to discriminate between workers at high and low risk of premature work exit was analyzed by the area (AUC) under the receiver operating characteristic curve. 9,530 (83 %) construction workers had complete data for analysis. At follow-up, 336 (4 %) workers reported disability pension, 125 (1 %) unemployment, and 255 (3 %) retirement. WAI scores were prospectively associated with the risk of disability pension at follow-up, but not with the risk of unemployment and early retirement. The WAI showed fair discrimination to identify workers at risk of disability pension [AUC = 0.74; 95 % confidence interval (CI) 0.70-0.77]. The discriminative ability decreased with age from AUC = 0.78 in workers aged 30-39 years to AUC = 0.69 in workers ≥50 years of age. Discrimination failed for unemployment (AUC = 0.51; 95 % CI 0.47-0.55) and early retirement (AUC = 0.58; 95 % CI 0.53-0.61). The WAI can be used to identify construction workers risk of disability pension and invite them for preventive interventions.

    Full Text Available Background. Depressive disorders are associated with substantial risk of premature mortality. A number of factors may contribute to reported risk estimates, making it difficult to determine actual risk of excess mortality in community cases of depression. The aim of this study is to conduct a systematic review and meta-analysis of excess mortality in population-based studies of clinically defined depression. Methods. Population-based studies reporting all-cause mortality associated with a clinically defined depressive disorder were included in the systematic review. Estimates of relative risk for excess mortality in population-representative cases of clinical depressive disorders were extracted. A meta-analysis was conducted using Stata to pool estimates of excess mortality and identify sources of heterogeneity within the data. Results. Twenty-one studies reporting risk of excess mortality in clinical depression were identified. A significantly higher risk of mortality was found for major depression (RR 1.92 95% CI 1.65–2.23, but no significant difference was found for dysthymia (RR 1.37 95% CI 0.93–2.00. Relative risk of excess mortality was not significantly different following the adjustment of reported risk estimates. Conclusion. A mortality gradient was identified with increasing severity of clinical depression. Recognition of depressive symptoms in general practice and appropriate referral for evidence-based treatment may help improve outcomes, particularly in patients with comorbid physical disorders.

    Purpose: The purpose of this study is to determine the incidence of retinopathy of prematurity (ROP) and the maternal/neonatal risk factors at a tertiary care hospital in Oman, compared to other countries. Patients and Methods: A retrospective analysis of premature neonates born with gestational age (GA) 24–32 weeks at Sultan Qaboos University Hospital, Oman, from January 2007 to December 2010. Maternal and neonatal in-hospital course was retrieved. The incidence of ROP was reported. Risk factors analyses were performed using univariate and multivariate statistics. Results: A total of 171 neonates (57% males, 43% females) were included for analysis. The incidence of ROP (any stage) was 69/171 (40.4%). Infants with ROP had significantly lower GA (27.7±2 weeks) compared to non-ROP group (30.2±1.7 weeks), P patent ductus arteriosus, seizures, and number of blood transfusions. There was no significant difference in maternal characteristics between the ROP and non-ROP groups except that mothers of infants with ROP were found to be significantly younger. Logistic regression analysis revealed early GA, low BW, duration of Oxygen therapy, and late-onset clinical or proven sepsis as independent risk factors. Conclusion: ROP is still commonly encountered in neonatal practice in Oman and other countries. Early GA, low BW, and prolonged oxygen therapy continue to be the main risk factors associated with the occurrence of ROP in our setting. In addition, an important preventable risk factor identified in our cohort includes clinical or proven late-onset sepsis. PMID:28298861

    Objectives To estimate the incidence of severe retinopathy of prematurity (ROP) requiring treatment and describe current treatment patterns in the UK. Design Nationwide population-based case ascertainment study via the British Ophthalmic Surveillance Unit and a national collaborative ROP special interest group. Practitioners completed a standardised case report form (CRF). Setting All paediatric ophthalmologists providing screening and/or treatment for retinopathy in the UK were invited to take part. Participants Any baby with ROP treated or referred for treatment between 1 December 2013 and 30 November 2014, treated with laser, cryotherapy, vascular endothelial growth factor (VEGF) inhibitor or vitrectomy/scleral buckling, or a combination. Main outcome measure Incidence of ROP requiring treatment. Results We received 370 CRFs; 327 were included. Denominator from epidemiological data: 8112 infants with birth weight of <1500 g. The incidence of ROP requiring treatment was 4% (327/8112, 95% CI 3.6% to 4.5%). Median gestational age was 25 weeks (IQR 24.3–26.1), and median birth weight 706 g (IQR 620–821). Median age at first treatment was 80 days (IQR 71–96). 204 right eyes (62.39%) had type 1 ROP, and 27 (8.26%) had aggressive posterior ROP. Infants were also treated for milder disease: 9 (2.75%) right eyes were treated for type 2 ROP, and 74 (22.63%) for disease milder than type 1 with plus or preplus, which we defined here as ‘type 2 plus’ disease. First-line treatment was diode laser photoablation of the avascular retina in 90.5% and injection of VEGF inhibitor in 8%. Conclusions ROP treatment incidence in the UK is 2.5 times higher than previously estimated. 8% of treated infants receive intravitreal VEGF inhibitor, currently unlicensed. Research is needed urgently to establish safety and efficacy of this approach. Earlier treatment and increasing numbers of surviving premature infants require an increase in appropriate eye care facilities and

    The aim of this study was to investigate if individuals born with sub-optimal birth characteristics have reduced probability of reproducing in adulthood. Using population-based registries, the authors included 522 216 males and 494 692 females born between 1973 and 1983 and examined their reproductive status as of 2006. Outcome measure was the hazard ratio (HR) of reproducing. Adjustments were made for socio-economic factors. Males and females born very premature displayed a reduced probability of reproducing [HR = 0.78, 95% confidence interval (CI): 0.70-0.86 for males; HR = 0.81, CI: 0.75-0.88 for females]. Likewise for very low birthweight (HR = 0.83, CI: 0.71-0.95 for males; HR = 0.80, 95% CI: 0.72-0.89 for females). Individuals born large for gestational age (LGA) displayed no significant changes. Males born small for gestational age (SGA) had a 9% lower reproductive rate (CI: 0.89-0.94) and that reduction increased as the individuals aged. Women born SGA tended to start reproducing at an earlier age. The results suggest that being born with low birthweight, premature or SGA (for males) is associated with a reduced probability of reproducing as an adult. LGA shows no statistically significant relationship with future reproduction.

    Purpose of Review This review will examine the unique susceptibility of premature infants to oxidative stress, the role of reactive oxygen species (ROS) in the pathogenesis of common disorders of the preterm infant, and potential for therapeutic interventions using enzymatic and/or non-enzymatic antioxidants. Recent Findings Oxidative stress is caused by an imbalance between the production of ROS and the ability to detoxify them with the help of antioxidants. The premature infant is especially susceptible to ROS-induced damage because of inadequate antioxidant stores at birth, as well as impaired upregulation in response to oxidant stress. Thus, the premature infant is at increased risk for the development of ROS-induced diseases of the newborn, such as bronchopulmonary dysplasia, retinopathy of prematurity, necrotizing enterocolitis, and periventricular leukomalacia. Summary Potential therapies for ROS-induced disease include both enzymatic and non-enzymatic antioxidant preparations. More research is required to determine the beneficial effects of supplemental antioxidant therapy. PMID:21150443

    Premature birth is a significant cause of infant and child morbidity and mortality. In the United States, the premature birth rate, which had steadily increased during the 1990s and early 2000s, has decreased annually for 7 years and is now approximately 11.39%. Human viability, defined as gestational age at which the chance of survival is 50%, is currently approximately 23 to 24 weeks in developed countries. Infant girls, on average, have better outcomes than infant boys. A relatively uncomplicated course in the intensive care nursery for an extremely premature infant results in a discharge date close to the prenatal estimated date of confinement. Despite technological advances and efforts of child health experts during the last generation, the extremely premature infant (less than 28 weeks gestation) and extremely low birth weight infant (death and disability with 30% to 50% mortality and, in survivors, at least 20% to 50% risk of morbidity. The introduction of continuous positive airway pressure, mechanical ventilation, and exogenous surfactant increased survival and spurred the development of neonatal intensive care in the 1970s through the early 1990s. Routine administration of antenatal steroids during premature labor improved neonatal mortality and morbidity in the late 1990s. The recognition that chronic postnatal administration of steroids to infants should be avoided may have improved outcomes in the early 2000s. Evidence from recent trials attempting to define the appropriate target for oxygen saturation in preterm infants suggests arterial oxygen saturation between 91% and 95% (compared with 85%-89%) avoids excess mortality; however, final analyses of data from these trials have not been published, so definitive recommendations are still pending. The development of neonatal neurocritical intensive care units may improve neurocognitive outcomes in this high-risk group.

    determinación de los riesgos vitales relacionados a condiciones del nacimiento, crecimiento y desenvolvimiento infantil, siendo estos aspectos componentes de varios indicadores de salud y fundamentales para la asistencia materno-infantil.The objective was to identify the profile of mothers and premature births and characterize the premature newborns at risk for growth and development. A cross-sectional epidemiological study conducted in Guarapuava PR. The data were obtained through the information system on live births (SINASC based on declarations of live births. The statistical analysis was performed on a sample composed by 106 live births premature declarations, of January to June 2005, and their mothers. The used variables were: characteristics sociodemographics, the gestation period and child-birth conditions, and characteristics of the alive born infants. It was concluded that knowing and evaluating the mothers' profile, the number and situation of the children's of a birth area, in a period of time, is important in the determination of the vital risks related to conditions of the birth, growth and infantile development, being these component aspects of several health indicators, and fundamental for the attendance in the maternal-infantile area.

    Full Text Available Studies in preterm infants have shown that prolonged treatment with topical iodine (multiple doses, often over multiple days can transiently suppress thyroid function. However, it is uncertain if topical iodine exposure for very short periods of time can cause significant changes in thyroid function. We report two cases of transient hypothyroidism in preterm infants after short-term exposure to topical iodine during surgical preparation, and review their clinical and laboratory findings before and after iodine exposure. We conclude that premature infants are at risk of developing transient hypothyroidism in response to a single, short-term exposure to topical iodine, even in iodine-sufficient geographical areas. We advise monitoring of thyroid function in these infants after iodine exposure, as treatment with levothyroxine may be needed for a limited duration to prevent the sequelae of untreated hypothyroidism. Consideration of using alternative cleansing agents is also advised.

    The purpose of this review is to present the strategies for fertility preservation that are currently proposed to patients at risk from premature ovarian failure (POF) due to chemotherapy as well as some future solutions that could allow patients already affected by an IOP to recover their fertility. Today, cryo-preservation of pieces of ovarian cortex followed by orthotopic transplantation as well as in vitro maturation of oocytes (IVM) allow preservation of fertility in patients being to undergo an antitumor treatment. However, although promising results have been obtained, the pregnancy rate remains very low. Improvement of these techniques, but also stimulation of resting follicle activation, in vitro folliculogenesis, and culture of putative oogonia that may be present in the adult ovary, are all future opportunities for patients suffering from an IOP, and are currently the subject of intensive researches.

    Full Text Available Although a number of studies have investigated correlations of maternal age with birth outcomes, an extensive assessment using age as a continuous variable is lacking. In the current study, we estimated age-specific risks of adverse birth outcomes in childbearing women.National population-based data containing maternal and neonatal information were derived from the Health Promotion Administration, Taiwan. A composite adverse birth outcome was defined as at least anyone of stillbirth, preterm birth, low birth weight, macrosomia, neonatal death, congenital anomaly, and small for gestational age (SGA. Singletons were further analyzed for outcomes of live birth in relation to each year of maternal age. A log-binomial model was used to adjust for possible confounders of maternal and neonatal factors.In total, 2,123,751 births between 2001 and 2010 were utilized in the analysis. The risk of a composite adverse birth outcome was significantly higher at extreme maternal ages. In specific, risks of stillbirth, neonatal death, preterm birth, congenital anomaly, and low birth weight were higher at the extremes of maternal age. Furthermore, risk of macrosomia rose proportionally with an increasing maternal age. In contrast, risk of SGA declined proportionally with an increasing maternal age. The log-binomial model showed greater risks at the maternal ages of 30 years for a composite adverse birth outcome.Infants born to teenagers and women at advanced age possess greater risks for stillbirth, preterm birth, neonatal death, congenital anomaly, and low birth weight. Pregnancies at advanced age carry an additional risk for macrosomia, while teenage pregnancies carry an additional risk for SGA. The data suggest that the optimal maternal ages to minimize adverse birth outcomes are 26∼30 years.

    According to many national recommendations, women should be physically active during pregnancy, but empirical evidence to support this recommendation is sparse. The authors' aim in this study was to examine the relation between physical exercise during pregnancy and the risk of preterm birth. Self......-reported data on physical exercise during pregnancy were collected prospectively for 87,232 singleton pregnancies included in the Danish National Birth Cohort between 1996 and 2002.

    This study examined risk and protective factors associated with very low birth weight (VLBW) for babies born to women receiving adequate or inadequate prenatal care. Birth records from St. Louis City and County from 2000 to 2009 were used (n = 152,590). Data was categorized across risk factors and stratified by adequacy of prenatal care (PNC). Multivariate logistic regression and population attributable risk (PAR) was used to explore risk factors for VLBW infants. Women receiving inadequate prenatal care had a higher prevalence of delivering a VLBW infant than those receiving adequate PNC (4.11 vs. 1.44 %, p inadequate PNC regarding Black race (36.4 vs. 79.0 %, p inadequate PNC. Among women with inadequate PNC, Medicaid was protective against (aOR 0.671, 95 % CI 0.563-0.803; PAR -32.6 %) and smoking a risk factor for (aOR 1.23, 95 % CI 1.01, 1.49; PAR 40.1 %) VLBW. When prematurity was added to the adjusted models, the largest PAR shifts to education (44.3 %) among women with inadequate PNC. Community actions around broader issues of racism and social determinants of health are needed to prevent VLBW in a large urban area.

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

    Preterm birth defined as birth prior to 37 weeks of gestation is caused by different risk factors and implies an increased risk for disease and early death for the child. The aim of the study was to investigate the effect of maternal stress during pregnancy on the risk of preterm birth. A case-control study that included 340 women; 168 women who gave birth preterm and 172 women who gave birth at term. Data were manually extracted from standardized medical records. If the medical record contained a psychiatric diagnosis or a self-reported stressor e.g., depression or anxiety the woman was considered to have been exposed to stress during pregnancy. Adjusted odds ratio (AOR) was used to calculate the attributable risk (AR) of maternal stress during pregnancy on preterm birth, both for the women exposed to stress during pregnancy (AR1 = (AOR-1)/AOR) and for the whole study population (AR2 = AR1*case fraction). Maternal stress during pregnancy was more common among women who gave birth preterm compared to women who gave birth at term (p stress during pregnancy 54% gave birth preterm with stress as an attributable risk factor. Among all of the women the percentage was 23%. Stress seems to increase the risk of preterm birth. It is of great importance to identify and possibly alleviate the exposure to stress during pregnancy and by doing so try to decrease the preterm birth rate.

    Full Text Available Objectives: Preterm premature rupture of membranes (PPROM is defined as a rupture of the amniotic membranes occurring before 37 weeks of gestation and before the onset of labor. Extreme PPROM occurs prior to 26 weeks gestation and contributes to an increased risk of prematurity, leading to maternal and fetal complications. This study aims to estimate the risk factors associated with various maternal complications and to determine the worst outcomes in Omani females with extreme PPROM.Methods: A retrospective cohort study was conducted on 44 women with extreme PPROM, who delivered at Sultan Qaboos University Hospital (SQUH from January 2006 to December 2011. Women with incomplete information, multiple gestations, or a preterm delivery resulting from medical intervention, as well as women who delivered elsewhere were excluded from the study.Results: Forty-four women with extreme PPROM were included in our study. The results revealed the most important risk factor to be history of infection, which was noted in 24 study participants. The mean maternal age was 30 years. The mean gestational age at PPROM and at delivery were 20.7±3.2 (range: 16-26 weeks and 29.7±7.6 weeks (range: 17-40 weeks, respectively. The maternal complications observed in this study included; infection which was seen in 20 (45% patients, antepartum hemorrhage in 11 (25% patients, and cesarean section which was required in 12 (27% patients. There was no significant association between risk factors such as gestational age at delivery, parity, maternal age at PPROM, or maternal Body Mass Index (BMI and cesarean section rate. Infection played a major role, both as a risk factor and in causing extreme PPROM, which in turn increased in 12 patients (27%. In the multivariable model for predicting the need for cesarean section (gestational age at delivery, parity, maternal age at PPROM in years and maternal BMI, none of the factors were statistically significant.Conclusion: Overall

    To examine the association between a spectrum of 24 maternal occupations and 45 birth defects for hypothesis generating purposes. Cases of isolated and multiple birth defects (n = 8977) and all non-malformed live-born control births (n = 3833) included in the National Birth Defects Prevention Study (NBDPS) with estimated dates of delivery from 1 October 1997 through 31 December 2003 were included. A computer-assisted telephone interview with mothers was conducted. Occupational coding using the 2000 Standard Occupational Classification System and the 1997 North American Industry Classification System was completed for all jobs held by mothers. Jobs held from 1 month before pregnancy to the end of the third pregnancy month were considered exposures. Logistic regression models were run, adjusted for potential confounders. We also used a Bayesian approach to logistic regression. Approximately 72% of case mothers and 72% of control mothers in the NBDPS were employed. Several occupational groups were positively associated with one or more birth defects, including janitors/cleaners, scientists and electronic equipment operators. Using standard logistic regression, we found 42 (26 for Bayesian) significantly elevated risks of birth defects in offspring of working mothers. In addition, several other occupational groups were found to be negatively associated with one or more birth defects, including teachers and healthcare workers. Using standard logistic regression, we found 12 (11 for Bayesian) significantly reduced risks of birth defects among offspring of working women. Results from these analyses can be used for hypothesis generating purposes and guiding future investigations of occupational exposures and birth defects.

    Level of prematurity is an objective criterion for determining the health welfare of the population. Several family background factors of the mother increases the risk of preterm birth child - family status, unwanted pregnancy, etc. Pregnancy among unmarried women and unwanted pregnancy are associated with a higher risk of giving premature baby. Aim of this study is a survey and analysis of factors of family background of the mother (family status and unplanned pregnancy) and their influence on the birth of a premature baby. The survey found nearly three times higher risk OR = 2,83 95 % CI (1,7-4,7) for the birth of a premature baby among unmarried mothers compared to married women, and twice as high proportion of unplanned pregnancy mothers of preterm infants - 20.7% compared to terminfants-10.4%.

    Preterm premature rupture of membranes (PPROM) is associated with inflammation and infection, and it may involve the loss of a barrier to ascending infection from the vagina, and it is possible that prolonged PPROM could be an independent risk factor for neonatal sepsis. The objective of the study was to determine whether prolonged latency after PPROM is associated with an increased risk of neonatal sepsis. This secondary analysis of the randomized controlled trial of magnesium sulfate for the prevention of cerebral palsy evaluated whether the time interval between diagnosis of PPROM and delivery was associated with an increased risk of neonatal sepsis. Latency time was categorized by weeks of latency (0 weeks to ≥ 4 weeks). The primary outcome was confirmed neonatal sepsis. Logistic regression was used to control for confounders. A total of 1596 patients with PPROM were analyzed, of whom 1390 had a neonatal sepsis occurred in 15.5% of patients in the cohort. In the univariate analysis, patients in the prolonged PPROM group were less likely to have neonatal sepsis (6.8% vs 17.2%, relative risk, 0.40 95% confidence interval, 0.24-0.66). This relationship was retained in the multivariable model; patients with prolonged PPROM ≥ 4 weeks had an adjusted odds ratio of 0.21 (95% confidence interval, 0.10-0.41) for neonatal sepsis. Neonatal sepsis was also significantly associated with earlier gestational age at rupture of membranes. Prolonged exposure to an intrauterine environment of PPROM does not increase the risk of neonatal sepsis; prolonged PPROM ≥ 4 weeks was associated with decreased risk of neonatal sepsis.

    White matter tracts mature asymmetrically during development, and this development can be studied using diffusion magnetic resonance imaging. The aims of this study were i. to generate dynamic population-averaged white matter registration templates covering in detail the period from 25 weeks gestational age to term, and extending to 2 years of age based on DTI and fractional anisotropy, ii. to produce tract-specific probability maps of the corticospinal tracts, forceps major and forceps minor using probabilistic tractography, and iii. to assess the development of these tracts throughout this critical period of neurodevelopment. We found evidence for asymmetric development across the fiber bundles studied, with the corticospinal tracts showing earlier maturation (as measured by fractional anisotropy) but slower volumetric growth compared to the callosal fibers. We also found evidence for an anterior to posterior gradient in white matter microstructure development (as measured by mean diffusivity) in the callosal fibers, with the posterior forceps major developing at a faster rate than the anterior forceps minor in this age range. Finally, we report a protocol for delineating callosal and corticospinal fibers in extremely premature cohorts, and make available population-averaged registration templates and a probabilistic tract atlas which we hope will be useful for future neonatal and infant white-matter imaging studies.

  20. Development and application of human virtual excitable tissues and organs: from premature birth to sudden cardiac death.

    Holden, Arun V

    2010-12-01

    The electrical activity of cardiac and uterine tissues has been reconstructed by detailed computer models in the form of virtual tissues. Virtual tissues are biophysically and anatomically detailed, and represent quantitatively predictive models of the physiological and pathophysiological behaviours of tissue within an isolated organ. The cell excitation properties are quantitatively reproduced by equations that describe the kinetics of a few dozen proteins. These equations are derived from experimental measurements of membrane potentials, ionic currents, fluxes, and concentrations. Some of the measurements were taken from human cells and human ion channel proteins expressed in non-human cells, but they were mostly taken from cells of other animal species. Data on tissue geometry and architecture are obtained from the diffusion tensor magnetic resonance imaging of ex vivo or post mortem tissue, and are used to compute the spread of current in the tissue. Cardiac virtual tissues are well established and reproduce normal and pathological patterns of cardiac excitation within the atria or ventricles of the human heart. They have been applied to increase the understanding of normal cardiac electrophysiology, to evaluate the candidate mechanisms for re-entrant arrhythmias that lead to sudden cardiac death, and to predict the tissue level effects of mutant or pharmacologically-modified ion channels. The human full-term virtual uterus is still in development. This virtual tissue reproduces the in vitro behaviour of uterine tissue biopsies, and provides possible mechanisms for premature labour.

    2016-07-01

    Objective To examine the perception of risk among a group of women with high risk pregnancies who were either planning to give birth in hospital, or at home despite medical advice to the contrary. The intention was to consider differences and similarities between the groups to examine how perception of risk relates to choice of place of birth. Design Qualitative study using semi-structured interviews. Setting Maternity department in a hospital in South East England. Participants Twenty-six women with high risk pregnancies, at least 32 weeks pregnant. Half were planning hospital births and half homebirths. Measurements and findings Semi-structured interviews to investigate women's understanding and assessment of risk. Results were analysed using thematic analysis. Five themes emerged: understanding of situation; judgement of risk; reassuring factors; impact of risk; and coping with risk. Women from both groups had some understanding of the implications of their medical/obstetric conditions. They displayed concerns about their babies' wellbeing. Women planning homebirths assessed their risks as lower and expressed less concerns than women planning hospital births. Women planning hospital births more frequently described following professional advice. Key conclusions Risk perception is individual and subjective. Women with high risk pregnancies who plan to give birth at home perceive risk differently to women who plan hospital births. Implications for practice Healthcare professionals working with women with high risk pregnancies should be aware of the potential for differences in definitions and perceptions of risk within this group.

    Full Text Available Introduction: Pneumothorax is a life threatening condition, more often seen in immature infants receiving mechanical ventilation. It carries a significant risk of death and impaired outcome.Objective: To determine predictive factors for the occurrence of pneumothorax in preterm infants with respiratory distress syndrome (RDS.Patients and methods: The present study was conducted in a tertiary research and educational hospital, NICU, Pediatric Clinic UKC Sarajevo, from January 2010 to December 2013. All infants had chest X-ray at admission, and were treated due to RDS with nasal continuous positive airway pressure (CPAP, mechanical ventilation, or high frequency oscillatory ventilation. At admission we registered data regarding birth weight, gestational age, Apgar score, prenatally given steroids. Inclusion criteria were fulfilled by 417 infants. Data about timing, circumstances, side and treatment of pneumothorax were gathered from medical records.Results: Mean birth weight was 1,477 g, mean gestational age 29.6 weeks. We report 98 infants who did not survive. We also report incidence of pneumothorax in 5% of the infants with RDS. In this study pneumothorax and non-pneumothorax groups didn’t differ regarding sex, gestational age (median 29 and 30 nor birth weight (p = 0.818. Apgar score at the 1st and 5th minute of life had no influence in genesis of pulmonary air leak, neither prenatally given steroids (p = 0.639, nor surfactant administration. There was a low coverage of preterm infants with prenatal steroids (overall 28.29%. We found that FiO2 ≥ 0.4 in the first 12 hours of life, and need for mechanical ventilation are predicting factors for developing pneumothorax (p < 0.05.Conclusion: Together with mechanical ventilation, inspired fraction of oxygen higher than 40%, needed to provide adequate oxygenation in the first 12 hours of life in preterm infants, could be a predictive factor in selecting the highest risk babies for development of

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

Methods A total of 515 premature infants with a gestational age of less than 36 weeks who were delivered in our hospital from October 2011 to October 2012 were screened for retinopathy. Factors were analyzed by univarite and multivariate Logistics regression analysis, such as the premature infants' sex, gestational age, birth weight, anemia, acidosis, hypoglycemia, oxygen inhalation, pneumonia, blood infusion. Results The screening test showed that 82 of 515 premature infants had retinopathy and the morbidity was 15.9%. Eighty cases of retinopathy of prematurity were treated after retinal laser photocoagulation and followed up for half a year with a good condition. Univariate analysis result showed that gestational age, birth weight, pneumonia, oxygen inhalation, hypoglycemia, anemia, blood infusion were the major risk factors related to retinopathy in premature infants. Multivariate analysis result showed that birth weight and oxygen inhalation were the key factors relative to retinopathy of prematurity. Conclusion Birth weight and oxygen inhalation of premature infants are the key factors related to retinopathy. Early screening, diagnosis and treatment can effectively control the progression and decrease the rate of blindness in premature infants.%目的:筛查早产儿视网膜病变情况以及分析影响早产儿视网膜病变的危险因素。方法选取2011年10月~2012年10月期间在我院分娩的胎龄小于36周早产儿515例作为研究对象。对早产儿进行眼部筛查,是否有视网膜病变的情况。根据早产儿的性别、胎龄、出生体重、贫血、酸中毒、低血糖血症、吸氧、肺炎以及输血史等因素进行单因素和多因素Logistic回归分析。结果515例早产儿眼部检查发现82例出现视网膜病变,病变率为15.9%,经过视网膜激光光凝术治疗后80例手

    Full Text Available Single-nucleotide polymorphisms (SNPs in the protein phosphatase and actin regulator 1 gene (PHACTR1 have been associated with susceptibility to develop several diseases, including cardiovascular disease. The purpose of this study was to evaluate the role of two polymorphisms (rs2026458 and rs9349379 of the PHACTR1 gene in the susceptibility to the risk of developing premature coronary artery disease (CAD in the Mexican population. The genotype analysis was performed using 5’exonuclease TaqMan genotyping assays in a group of 994 patients with premature CAD and 703 controls. A similar genotype distribution of rs2026458 was observed in both groups; however, under an additive model adjusted by age, body mass index, type 2 diabetes mellitus, smoking, dyslipidemia, and hypertension, the rs9349379 G allele was associated with a higher risk for developing premature CAD (odds ratio (OR = 1.22, 95% confidence interval (CI = 1.03–1.46, p-value (p = 0.024. The two PHACTR1 polymorphisms were not in linkage disequilibrium. In summary, our results suggest that the PHACTR1 rs9349379 polymorphism plays an important role in the risk of developing premature CAD in the Mexican population.

    Full Text Available BACKGROUND: This study aimed to determine the prevalence of genetic and environmental vascular risk factors in non diabetic patients with premature peripheral arterial disease, either peripheral arterial occlusive disease or thromboangiitis obliterans, the two main entities of peripheral arterial disease, and to established whether some of them are specifically associated with one or another of the premature peripheral arterial disease subgroups. METHODS AND RESULTS: This study included 113 non diabetic patients with premature peripheral arterial disease (diagnosis <45-year old presenting either a peripheral arterial occlusive disease (N = 64 or a thromboangiitis obliterans (N = 49, and 241 controls matched for age and gender. Both patient groups demonstrated common traits including cigarette smoking, low physical activity, decreased levels of HDL-cholesterol, apolipoprotein A-I, pyridoxal 5'-phosphate (active form of B6 vitamin and zinc. Premature peripheral arterial occlusive disease was characterized by the presence of a family history of peripheral arterial and carotid artery diseases (OR 2.3 and 5.8 respectively, 95% CI, high lipoprotein (a levels above 300 mg/L (OR 2.3, 95% CI, the presence of the factor V Leiden (OR 5.1, 95% CI and the glycoprotein Ia(807T,837T,873A allele (OR 2.3, 95% CI. In thromboangiitis obliterans group, more patients were regular consumers of cannabis (OR 3.5, 95% CI and higher levels in plasma copper has been shown (OR 6.5, 95% CI. CONCLUSIONS: According to our results from a non exhaustive list of study parameters, we might hypothesize for 1 a genetic basis for premature peripheral arterial occlusive disease development and 2 the prevalence of environmental factors in the development of thromboangiitis obliterans (tobacco and cannabis. Moreover, for the first time, we demonstrated that the 807T/837T/873A allele of platelet glycoprotein Ia may confer an additional risk for development of peripheral

    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.

    Epidemiological studies have suggested that arterial hypertension is a chronic disease that begins in childhood, and that prematurity (birth at less than 37 weeks' gestational age) is potentially associated with the development of hypertension in childhood and adulthood. Our objective was to identify the association between prematurity and high blood pressure in children, using a systematic literature review. Original articles related to the theme and published in English, Portuguese, or Spanish from 1998 to 2009 were selected from the MEDLINE, LILACS, and SciELO databases. We excluded articles without abstracts, review articles, and articles not related to prematurity and hypertension in childhood. Nine articles were located and analyzed: 5 case-control studies, 2 cross-sectional studies, and 2 cohort studies. The majority of the studies failed to show an association between prematurity and arterial hypertension in childhood. However, the influence of prematurity should not be ruled out, given the small number of studies on this theme and the diversity of methodological approaches in the literature.

    Traditional birth attendants (TBAs) can be invaluable in assisting to dispel myths commonly associated with natal/neonatal teeth. To ensure correct delivery of the message, baseline data of their beliefs is important. To assess the attitude and beliefs of some Nigerian TBAs to prematurely erupted teeth in infants, a total enumeration of the TBAs in the five urban Local Government Areas in Ibadan was conducted and 163 consenting TBAs were recruited using an interviewer-administered questionnaire. The attitude of the TBAs was that of fear and shock (35.6%) while 30 (18.4%) will consider the child weird. Perceived causes of the variation include evil spirits (31.9%), contravening cultural taboos (9.2%), and prolonged gestation (4.9%). Beliefs on the effect of natal/neonatal teeth on the child include strange behavior (31.3%), child developing evil spiritual powers (41.1%), and mental retardation (3.1%). Practices included advising parents to get rid of/or hide the child (4.9%) and immediate extraction of the teeth with/without sacrifices (35.6%). There is an urgent need to address knowledge gaps by giving health education to TBAs.

    Premature birth is a significant cause of infant and child morbidity and mortality. In the United States, the premature birth rate, which had steadily increased during the 1990s and early 2000s, has decreased annually for four years and is now approximately 11.5%. Human viability, defined as gestational age at which the chance of survival is 50%, is currently approximately 23–24 weeks in developed countries. Infant girls, on average, have better outcomes than infant boys. A relatively uncomplicated course in the intensive care nursery for an extremely premature infant results in a discharge date close to the prenatal EDC. Despite technological advances and efforts of child health experts during the last generation, the extremely premature infant (less than 28 weeks gestation) and extremely low birth weight infant (ELBW) (premature labor improved neonatal mortality and morbidity in the late 1990s. The recognition that chronic postnatal administration of steroids to infants should be avoided may have improved outcomes in the early 2000s. Evidence from recent trials attempting to define the appropriate target for oxygen saturation in preterm infants suggests arterial oxygen saturation between 91–95% (compared to 85–89%) avoids excess mortality. However, final analyses of data from these trials have not been published, so definitive recommendations are still pending The development of neonatal neurocognitive care visits may improve neurocognitive outcomes in this high-risk group. Long-term follow up to detect and address developmental, learning, behavioral, and social problems is critical for children born at these early gestational ages. The striking similarities in response to extreme prematurity in the lung and brain imply that agents and techniques that benefit one organ are likely to also benefit the other. Finally, since therapy and supportive care continue to change, the outcomes of ELBW infants are ever evolving. Efforts to minimize injury, preserve

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

    Lorenzo D Botto

    Full Text Available OBJECTIVE: Birth defects are an increasing health priority worldwide, and the subject of a major 2010 World Health Assembly Resolution. Excess cancer risk may be an added burden in this vulnerable group of children, but studies to date have provided inconsistent findings. This study assessed the risk for cancer in children and young adolescents with major birth defects. METHODS AND FINDINGS: This retrospective, statewide, population-based, cohort study was conducted in three US states (Utah, Arizona, Iowa. A cohort of 44,151 children and young adolescents (0 through 14 years of age with selected major, non-chromosomal birth defects or chromosomal anomalies was compared to a reference cohort of 147,940 children without birth defects randomly sampled from each state's births and frequency matched by year of birth. The primary outcome was rate of cancer prior to age 15 years, by type of cancer and type of birth defect. The incidence of cancer was increased 2.9-fold (95% CI, 2.3 to 3.7 in children with birth defects (123 cases of cancer compared to the reference cohort; the incidence rates were 33.8 and 11.7 per 100,000 person-years, respectively. However, the excess risk varied markedly by type of birth defect. Increased risks were seen in children with microcephaly, cleft palate, and selected eye, cardiac, and renal defects. Cancer risk was not increased with many common birth defects, including hypospadias, cleft lip with or without cleft palate, or hydrocephalus. CONCLUSION: Children with some structural, non-chromosomal birth defects, but not others, have a moderately increased risk for childhood cancer. Information on such selective risk can promote more effective clinical evaluation, counseling, and research.

    Hai Nguyen Thi

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

    The aim of this study was to determine whether the risk of stillbirth associated with male fetal sex was modified by fetal growth. The study group consisted of all singleton first births weighing greater than 500 g delivered between 28 and 43 weeks gestation in Scotland in 1980-1996 (n = 469,152). Overall, male fetuses were at an increased risk of stillbirth (relative risk = 1.19, 95 percent confidence interval: 1.10, 1.29). There was a significant negative interaction between male sex and increasing birth weight quintile in term, but not preterm, births. The interaction was virtually identical when calculated independently for births in the periods 1980-1987 and 1988-1996. There were linear decreases in the proportion of stillbirths and the proportion of birth weights in the lowest quintile over the period 1980-1996. Adjustment for year of birth did not affect the relation between male sex and stillbirth. However, adjustment for birth weight resulted in a loss of the association between year of birth and risk of stillbirth. The authors concluded that 1) the association between male sex and stillbirth diminishes with increasing birth weight quintile, and 2) there was a fall in the proportion of stillbirths in Scotland between 1980 and 1996, which may have been due to a fall in the proportion of small babies over the same period.

    Full Text Available To compare structural and functional outcome and time efficiency between standard spot sized conventional pulsed mode diode laser and continuous mode large spot transpupillary thermotherapy (LS TTT for treatment of high risk prethreshold retinopathy of prematurity (ROP. Ten eyes of five preterm babies having bilateral symmetrical high risk prethreshold ROP were included in this study. One eye of each baby was randomized to get either standard spot sized conventional pulsed mode diode laser or continuous mode LS TTT. There was no significant difference between structural or functional outcome in either group. The mean time taken for conventional diode laser was 20.07 minutes, while that for LS TTT was 12.3 minutes. LS TTT was 40% more time efficient than the conventional laser. It may be better suited for the very small fragile premature infants as it is quicker than the conventional laser.

In order to evaluate the frequency of retinopathy of prematurity and factors associated with its occurrence, the Chi-Squared or the Fisher Exact tests were used. Margin of error 5%. RESULTS: 228 premature babies did not present sings of retinopathy of prematurity (group 1 and 58 presented signs (group 2. The prevalence of retinopathy of prematurity was 20%, 9% being in stage 1; 7% in stage 2; 4% in stage 3 and 1% in stage 4a. The most involved factors were: birth weight (p<0.0001, oxygen therapy (p<0.0000, birth age (p=0.0006, lung disease (p=0.0041, blood transfusion (p=0.0002, central nervous system alterations (p=0.0259, serious infections (p=0.0278 and Apgar less than 7 in the first minute (p=0.0442. The premature babies that most needed treatment weighed less than 1,399 g and were 33 weeks old. CONCLUSION: According to the data the prevalence of retinopathy of prematurity was 20%. The premature babies' risks of retinopathy of prematurity were concentrated on weight below 1,400 g and age of 33 weeks. Bigger premature babies should be observed when one or more of the following factors are present: oxygen therapy, blood transfusion, lung disease, central nervous system alterations, serious infections and Apgar less than 7 in the first minute.

    The aim was to examine the relationship between maternal haemoglobin (Hb) concentrations and risk of preterm birth by secondary analysis of data from a randomised controlled trial. This analysis included 10,430 women who were at least 20 years old and no more than 20 weeks of gestation. Results revealed neither first- nor second-trimester Hb concentrations were associated with the risk of preterm births. However, the risk of preterm birth increased when the Hb level was low (preterm birth. A low-Hb level in the first trimester but coupled with a high Hb level in the second was associated with an elevated risk of preterm birth. Impact statement What is already known on this subject: The relationship between maternal Hb concentration and preterm birth remains inconclusive. Some studies have shown an association between a low- or a high-Hb level and an increased risk of preterm birth. Others have not found such an association. Yet others have shown a U-shaped relationship. What do the results of this study add: Overall, maternal Hb concentrations in first or second trimester were not statistically associated with the risk of preterm birth. However, women with a low Hb concentration in the first trimester together with a high Hb concentration in the second trimester had an increased risk of preterm birth, compared to women who had a higher Hb concentration in the first trimester that remained similar during the second trimester. What are the implications are of these findings for clinical practice and/or further research: Our finding helps identify mothers who are at risk of having a preterm delivery. Investigating the underlying clinical causes of the unfavourable change in Hb levels and close follow-up to these women may help improve birth outcomes.

    We examined the associations of mothers' perception of neighborhood quality and maternal resilience with risk of preterm birth and whether maternal resilience moderated the effect of neighborhood quality perception. We analyzed data from 10,758 women with singleton births who participated in 2010-2012 Los Angeles Mommy and Baby surveys. Multilevel logistic regression models assessed the effects of mothers' perception of neighborhood quality and maternal resilience on preterm birth (yes/no), controlling for potential confounders and economic hardship index, a city-level measure of neighborhood quality. Interaction terms were assessed for moderation. Mothers' perception of neighborhood quality and maternal resilience were each uniquely associated with preterm birth, independent of potential confounders (p-values perception of neighborhood quality and resilience are associated with the risk of preterm birth. Further research should explore whether initiatives aimed at improving neighborhood quality and women's self-esteem may improve birth outcomes.

    Genital tract infection accounts for approximately 25-40% of all preterm births. We sought to assess the relationship between preterm birth and selected vaginal bacterial taxa associated with preterm birth either directly or through their association with bacterial vaginosis (BV). Vaginal fluid for Gram stain was collected between 17 and 22 weeks' gestation as part of a randomized trial of ultrasound-indicated cerclage for preterm birth prevention in women at high risk for recurrent spontaneous preterm birth. Bacterial deoxyribonucleic acid was extracted from the Gram stain slides and analyzed using quantitative polymerase chain reaction. Among the 499 participants, Mycoplasma was positively correlated with increased risk of preterm (risk ratio [RR], 1.83; 95% confidence interval [CI], 1.52-2.22) as was Mobiluncus (RR, 1.36; 95% CI, 1.07-1.73) and Atopobium (RR, 1.44; 95% CI, 1.1-1.87). However, there were strong interactions between the race/ethnic group and the presence of these and other individual taxa on risk of preterm birth. By contrast, bacterial vaginosis-associated bacteria (BVAB)-3 was consistently associated with a reduction in the risk of preterm birth for all racial/ethnic groups (0.55; 95% CI, 0.39-0.78). BV is characterized by a reduction of Lactobacillus, and lactic acid-producing bacteria and the presence of Mobiluncus; we found these factors and the presence of Mycoplasma to be associated with an increased risk of preterm birth. By contrast, the presence of a recently identified organism sufficient to cause BV, BVAB3, decreased the risk of preterm birth. These findings give insight into why treating BV has mixed impact on risk of preterm birth. Copyright © 2014 Mosby, Inc. All rights reserved.

    Full Text Available The membranes surrounding the amniotic cavity are composed from amnion and chorion, tightly adherent layers which are composed of several cell types, including epithelial cells, trophoblasts cells and mesenchyme cells, embedded in a collagenous matrix. They retain amniotic fluid, secret substances into the amniotic fluid, as well as to the uterus and protect the fetus against upward infections from urogenital tract. Normally, the membranes it breaks during labor. Premature rupture of the amniotic sac (PRAS is defined as rupture of membranes before the onset of labor. Premature rupture of the fetal membrane, which occurs before 37 weeks of gestation, usually, refers to preterm premature rupture of membranes. Despite advances in the care period, premature rupture of membranes and premature rupture of membranes preterm continue to be regarded as serious obstetric complications. On the term 8% - 10% of pregnant women have premature rupture of membranes; these women are at increased risk of intrauterine infections, where the interval between membrane rupture and expulsion is rolled-over. Premature rupture of membranes preterm occurs in approximately 1% of all pregnancies and is associated with 30% -40% of preterm births. Thus, it is important to identify the cause of pre-term birth (after less than 37 completed weeks of "gestation" and its complications, including respiratory distress syndrome, neonatal infection and intraventricular hemorrhage. Objectives: the development of the protocol of the clinical trial on patients with impending preterm birth, study clinical and statistical on the socio-demographic characteristics of patients with imminent preterm birth; clinical condition of patients and selection of cases that could benefit from the application of interventional therapy; preclinical investigation (biological and imaging of patients with imminent preterm birth; the modality therapy; clinical investigation of the effectiveness of short

    Full Text Available Objective: To describe the activities of a multiprofessional outpatient clinic performed by neonatologist, physiatrist, physical therapist, occupational therapist, speech therapist, audiologist and psychologist, who evaluated the development of premature newborns. Methods: Twenty children born at a tertiary-care hospital (São Paulo, Brazil, between April 2006 and April 2007, with birth weight below 1250 g or less than 32 weeks of gestation, were evaluated. The multiprofessional evaluation included assessment of development using the Bayley III scale, at the corrected age of 3, 6, 9, 12, 18 and 24 months. Results: The mean gestation age at birth was 28.8 weeks; mean birth weight was 1055 g. The mean maternal age was 35 years and the mean length of stay of neonates was 46.3 days. Fifteen percent of children presented impaired sensory motor skills, 20% had hearing abnormalities and 10% motor alterations. Bayley III showed alterations in the communication area in 10% of subjects and in the motor area in 10% of individuals. The parents were oriented to stimulate the child or a specific intervention was suggested. The major development delay was observed between 6 and 18 months of age and the development was improved at 24 months of age. Conclusions: Most children evaluated had improved growth and development at 24 corrected-age months. Further studies with a larger sample are recommended, as well as the possibility to follow this population group up till the primary school.

    Analogous to rapid ventricular pacing, frequent ventricular premature complexes (VPCs) can predispose over time to cardiomyopathy and subsequent heart failure (HF). We examined the association of frequent VPCs with HF incidence in a population-based cohort, free of HF and coronary heart disease at baseline. At study baseline (1987 to 1989), ≥1 VPC on a 2-minute rhythm electrocardiographic strip was seen in 5.5% (739 of 13,486) of the middle-age (45 to 64 years old at baseline) white and black, men and women of the Atherosclerosis Risk In Communities cohort. Incident HF was defined as the first appearance of International Classification of Diseases code 428.x in the hospital discharge record or death certificate through 2005. During an average follow-up of 15.6 years, incident HF was seen in 10% the participants (19.4% of those with VPCs vs 9.4% of those without). The age-, race-, and gender-adjusted hazard ratio of HF for VPCs was 1.89 (95% confidence interval 1.59 to 2.24). After multivariable adjustment for potential confounders, the hazard ratio of HF for those with any VPC versus no VPC was 1.63 (95% confidence interval 1.36 to 1.96). After additional adjustment for incident coronary heart disease as a time-varying covariate, the hazard ratio was 1.71 (95% confidence interval 1.42 to 2.08). Those with a greater frequency of VPCs or complex VPCs had similar rates of HF compared to those with a single VPC and all had rates greater than those with no VPC. In conclusion, in this large population-based cohort, the presence of VPCs was associated with incident HF, independent of incident coronary heart disease.

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.

    With the gradual increase of global warming, the impact of extreme temperatures on health has become a focus of attention, however, its relationship with preterm birth remains unclear. To investigate the association between exposure to extreme temperatures and preterm birth. Temperature exposures and birth outcomes of 1,020,471 pregnant women from 132 cities in China were investigated. The pregnancy process was divided into different pregnancy periods. Study areas were divided into three categories (cold, medium, and hot areas) according to the local average temperature by cluster analysis. Average temperature data for each province used in the cluster analysis came from the China Statistical Yearbook 2013. Logistic regression was used to compare the effects of exposure to hot and cold conditions on the outcomes of pregnancy in different periods and regions. A total of 1,020,471 singleton births were included, of which 73,240(7.2%) were preterm births. Compared with moderate temperatures (5th to 95th percentile), heat exposure (>95th percentile) in different periods of pregnancy increased the risk of preterm birth in hot areas. The most obvious increase was during the 3 months before pregnancy (odds ratio (OR)=1.229, 95% confidence interval (CI): 1.166-1.295). In contrast to heat exposure, cold exposure (preterm birth; the protective effect was most pronounced in the 3 months before pregnancy (OR=0.784, 95% CI: 0.734-0.832). In medium and cold areas cold exposure also reduced the risk of preterm birth. The effect of exposure to extreme ambient temperatures throughout the entire pregnancy on preterm birth was similar to those of the periods above. Acute and chronic exposure to extreme temperatures may affect the risk of preterm birth. Extreme heat is a risk factor for preterm birth and extreme cold is a protective factor. Copyright © 2017.

    Full Text Available Abstract Background Objective: To compare the risk of placenta previa at second birth among women who had a cesarean section (CS at first birth with women who delivered vaginally. Methods Retrospective cohort study of 399,674 women who gave birth to a singleton first and second baby between April 2000 and February 2009 in England. Multiple logistic regression was used to adjust the estimates for maternal age, ethnicity, deprivation, placenta previa at first birth, inter-birth interval and pregnancy complications. In addition, we conducted a meta-analysis of the reported results in peer-reviewed articles since 1980. Results The rate of placenta previa at second birth for women with vaginal first births was 4.4 per 1000 births, compared to 8.7 per 1000 births for women with CS at first birth. After adjustment, CS at first birth remained associated with an increased risk of placenta previa (odds ratio = 1.60; 95% CI 1.44 to 1.76. In the meta-analysis of 37 previously published studies from 21 countries, the overall pooled random effects odds ratio was 2.20 (95% CI 1.96-2.46. Our results from the current study is consistent with those of the meta-analysis as the pooled odds ratio for the six population-based cohort studies that analyzed second births only was 1.51 (95% CI 1.39-1.65. Conclusions There is an increased risk of placenta previa in the subsequent pregnancy after CS delivery at first birth, but the risk is lower than previously estimated. Given the placenta previa rate in England and the adjusted effect of previous CS, 359 deliveries by CS at first birth would result in one additional case of placenta previa in the next pregnancy.

    Objetive We analyzed the role of environmental risk factors, socio-demographic characteristics, clinical characteristics, and reproductive history in preterm births and their associated perinatal outcomes in families classified according to their histories of preterm recurrence among siblings. Study Design A retrospective study was conducted at “Nuestra Señora de la Merced” Maternity Hospital in the city of Tucumán, Argentina. A total of 348 preterm, non-malformed, singleton children born to multipara women were reviewed. The family history score described by Khoury was applied, and families were classified as having no, medium or high genetic aggregation. Results Families with no familial aggregation showed a higher rate of short length of cohabitation, maternal urinary tract infections during the current pregnancy and maternal history of miscarriage during the previous pregnancy. Families with a high level of aggregation had a significantly higher incidence of pregnancy complications, such as diabetes, hypertension and immunological disorders. Conclusion Reproductive histories clearly differed between the groups, suggesting both a different response to environmental challenges based on genetic susceptibility, and the activation of different pathophysiological pathways to determine the duration of pregnancy in each woman.

Logistic regression analysis: mother pregnancy infection,vaginal delivery,septicemia,mechanical ventilation were independent risk factors for hemorrhagic brain injury,while the birth weight was its protective factor. Mechanical ventilation,septicemia,low carbonated hematic disease were independent risk factors for ischemic cerebral injury,while the prenatal use of cortical hormone and birth weight were its protective factors. Conclusions Therefore premature infant brain injury is a complex outcome of multiple factor interaction. Intrauterine exposure including prenatal mothers suffered from infection, perinatal hypoxia and infection after birth are.risk factors for encephalopathy in premature infants.

    The pathogenesis of autoimmune Addison's disease (AAD) is thought to be due to interplay of genetic, immune, and environmental factors. A month-of-birth effect, with increased risk for those born in autumn/winter months, has been described in autoimmune conditions such as type 1 diabetes and autoimmune thyroid disease. Month-of-birth effect was investigated in 2 independent cohorts of AAD subjects. The monthly distribution of birth in AAD patients was compared with that of the general population using the cosinor test. A total of 415 AAD subjects from the United Kingdom cohort were compared with 8 180 180 United Kingdom births, and 231 AAD subjects from the Polish cohort were compared with 2 421 384 Polish births. Association between month of birth and the susceptibility to AAD. In the entire cohort of AAD subjects, month-of-birth distribution analysis showed significant periodicity with peak of births in December and trough in May (P = .028). Analysis of the odds ratio distribution based on month of birth in 2 cohorts of patients with AAD versus the general population revealed a December peak and May trough, and January peak and July trough, in the United Kingdom and Polish cohorts, respectively. For the first time, we demonstrate that month of birth exerts an effect on the risk of developing AAD, with excess risk in individuals born in winter months and a protective effect when born in the summer. Exposure to seasonal viral infections in the perinatal period, coupled with vitamin D deficiency, could lead to dysregulation of innate immunity affecting the risk of developing AAD.

    BACKGROUND: Studies suggest that children born very preterm have a high risk of developmental coordination disorder (DCD). We examined the relation between the larger spectrum of gestational age at birth and the risk of DCD. METHODS:   We used the 7-year follow-up data from 22898 singletons...... in the Danish National Birth Cohort. We calculated a total score from the Developmental Coordination Disorder Questionnaire (DCDQ), incorporated in the 7-year follow-up, and defined children with a score of 46 or below as having probable DCD.

    BACKGROUND: Season of birth (SOB) has been regarded as a risk factor for atopy. The aim of this study was to explore the relationship between season of birth (SOB) and later development of atopic disease in children and adolescents. METHODS: A total of 1,007 randomly selected subjects, 7 to 17...... not significantly related to SOB. CONCLUSIONS: Atopy itself is independent of season of birth, whereas asthma is more prevalent among subjects born during the autumn. Regarding asthma, these results suggest that the first months of life enclose a period of particular vulnerability towards environmental risk factors...

    Full Text Available We examined the associations of mothers’ perception of neighborhood quality and maternal resilience with risk of preterm birth and whether maternal resilience moderated the effect of neighborhood quality perception. We analyzed data from 10,758 women with singleton births who participated in 2010–2012 Los Angeles Mommy and Baby surveys. Multilevel logistic regression models assessed the effects of mothers’ perception of neighborhood quality and maternal resilience on preterm birth (yes/no, controlling for potential confounders and economic hardship index, a city-level measure of neighborhood quality. Interaction terms were assessed for moderation. Mothers’ perception of neighborhood quality and maternal resilience were each uniquely associated with preterm birth, independent of potential confounders (p-values < 0.05. The risk of preterm birth among mothers who perceived their neighborhood as of poor quality was about 30% greater compared to mothers who perceived their neighborhood as of good quality; the risk was 12% greater among mothers with low resilience compared to those with high resilience. Effects of neighborhood quality were not modified by maternal resilience. The findings suggest that mothers’ perception of neighborhood quality and resilience are associated with the risk of preterm birth. Further research should explore whether initiatives aimed at improving neighborhood quality and women’s self-esteem may improve birth outcomes.

    Aims Despite agreement on the need for screening for the presence of cardiovascular risk factors in first-degree family members of patients with premature coronary artery disease (CAD), this is not routinely carried out in relatives of normocholesterolaemic patients. We evaluated cardiovascular risk factors in family members of normocholesterolaemic patients with premature CAD. Methods Eligible index subjects were patients with premature CAD (6.5 mmol/l were excluded. Sixteen index subjects were included with a mean age of 49±8 years and total cholesterol levels of 5.5±0.8 mmol/l. Sixty-four first-degree relatives from these 16 pedigrees were screened, namely 18 children, 42 siblings and four parents. National Cholesterol Education Program III guidelines were used to identify candidates for lipid-lowering treatment. Furthermore, the presence of four additional metabolic disorders was investigated: the metabolic syndrome, increased levels of lipoprotein(a) (Lp(a)), hyperhomocysteinaemia and postprandial hyperlipidaemia. Results Of 64 relatives free of CAD, 34 subjects (53%) fulfilled the criteria to receive therapeutic advice, 20 of whom (31% of the relatives) were candidates for drug therapy. Sixty-one relatives were available for a full assessment of metabolic disorders and in 37 relatives (61%) at least one metabolic abnormality was present. Twelve subjects had hyper-Lp(a), seven subjects had postprandial hyperlipidaemia and two had the metabolic syndrome. Furthermore, 16 subjects had a combination of at least two out of four metabolic disorders. Conclusion Careful evaluation of coronary risk factors and metabolic variables in first-degree relatives of normocholesterolaemic CAD patients identifies a significant number of subjects at increased coronary risk in whom primary prevention measures should be initiated.

    To investigate whether advanced maternal age is associated with preterm birth, irrespective of parity. Population-based registry study. Swedish Medical Birth Register. First, second, and third live singleton births to women aged 20 years or older in Sweden, from 1990 to 2011 (n = 2 009 068). Logistic regression analysis was used in each parity group to estimate risks of very and moderately preterm births to women at 20-24, 25-29, 30-34, 35-39, and 40 years or older, using 25-29 years as the reference group. Odds ratios (ORs) were adjusted for year of birth, education, country of birth, smoking, body mass index, and history of preterm birth. Age-related risks of spontaneous and medically indicated preterm births were also investigated. Very preterm (22-31 weeks of gestation) and moderately preterm (32-36 weeks) births. Risks of very preterm birth increased with maternal age, irrespective of parity: adjusted ORs in first, second, and third births ranged from 1.18 to 1.28 at 30-34 years, from 1.59 to 1.70 at 35-39 years, and from 1.97 to 2.40 at ≥40 years. In moderately preterm births, age-related associations were weaker, but were statistically significant from 35-39 years in all parity groups. Advanced maternal age increased the risks of both spontaneous and medically indicated preterm births. Advanced maternal age is associated with an increased risk of preterm birth, irrespective of parity, especially very preterm birth. Women aged 35 years and older, expecting their first, second, or third births, should be regarded as a risk group for very preterm birth. Women aged 35 years and older should be regarded as a risk group for very preterm birth, irrespective of parity. © 2016 Royal College of Obstetricians and Gynaecologists.

    2015-09-01

    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.

    Full Text Available Abstract Background A season of birth effect in immune-mediated diseases (ID such as multiple sclerosis and type 1 diabetes has been consistently reported. We aimed to investigate whether season of birth influences the risk of rheumatoid arthritis, Crohn's disease, ulcerative colitis and systemic lupus erythematosus in addition to multiple sclerosis, and to explore the correlation between the risk of ID and predicted ultraviolet B (UVB light exposure and vitamin D status during gestation. Methods The monthly distribution of births of patients with ID from the UK (n = 115,172 was compared to that of the general population using the Cosinor test. Predicted UVB radiation and vitamin D status in different time windows during pregnancy were calculated for each month of birth and correlated with risk of ID using the Spearman's correlation coefficient. Results The distributions of ID births significantly differed from that of the general population (P = 5e-12 with a peak in April (odds ratio = 1.045, 95% confidence interval = 1.024, 1.067, P P P = 0.00005 and third trimester vitamin D status (Spearman's rho = -0.44, P = 0.0003. Conclusions The risk of different ID in the UK is significantly influenced by the season of birth, suggesting the presence of a shared seasonal risk factor or factors predisposing to ID. Gestational UVB and vitamin D exposure may be implicated in the aetiology of ID.

    To determine risk factors during neonatal hospital stay and follow-up associated with failure to thrive in the first year of life of very low birth weight newborns. Study of preterm very low birth weight newborns followed from 2006 to 2013 in a public institutional hospital program. The study included newborns that attended at least one appointment in each of the three periods: Period I, up to 3 months of corrected age (CA); Period II, 4-6 months of CA; and Period III, 7-12 months of CA. The variables were analyzed by logistic regression with XLSTAT 2014 software (Microsoft®, WA, USA). Failure to thrive (Z-score below -2 SD) was classified as a dichotomous dependent variable (0 - failure/1 - success), while the other variables were classified as explanatory variables for the hospitalization periods and for each of the follow-up periods (I, II, and III). Children born adequate for gestational age increased the chance of Z-score for weight at discharge>-2 SD (OR=10.217; 95% CI: 1.117-93.436). Metabolic bone disease and retinopathy of prematurity in Period I, as well as hospital readmissions in Periods II and III during follow-up increased the chance of Z-score<-2 SD. Failure to thrive is influenced by intrauterine factors and, subsequently, by several morbidities, both in the birth and hospitalization period, as well as in the post-discharge period and thus, such variables should be prioritized in the follow-up.

    2015-10-01

    This study examined whether birth weight variation within the normal range was associated with language ability at 36 months, and whether responsive parenting-the putative protective factor-buffered children from the risk of relatively low birth weight. In all, 467 community mother-child dyads were followed longitudinally from birth. Receptive language was measured at 36 months. Responsive parenting was assessed through observed interactions at 18 months and examined as the hypothesized moderator. Controlling for confounds, both birth weight and responsive parenting positively predicted children's language skills. There was also a significant interaction between birth weight and responsive parenting-higher responsivity was associated with better language ability, and this link was especially pronounced for children at risk owing to relatively low birth weight. Normative differences in birth weight are a source of variability in children's language, but postnatal socialization factors such as parenting may buffer this risk. © The Author 2015.

    Full Text Available Objective. To examine the association of polycystic ovary syndrome (PCOS in early pregnancy with gestational diabetes mellitus (GDM and adverse birth outcomes. Methods. In this retrospective cohort study including 2389 pregnant women, the medical records of 352 women diagnosed with PCOS were evaluated. Outcomes included GDM, preterm birth, low birth weight, macrosomia, and being small and large for gestational age. Multivariable logistic regression models were used to examine the association of the risk for GDM and adverse birth outcomes with PCOS after adjusting for confounders. Results. Women previously diagnosed with PCOS had a higher risk of GDM (adjusted odds ratio [OR] 1.55, 95% confidence interval [CI]: 1.14–2.09. A strong association was seen between PCOS and preterm birth (adjusted OR 1.69, 95% CI: 1.08–2.67. On stratified analysis, the adjusted OR for GDM among women with PCOS undergoing assisted reproductive technology was 1.44 (95% CI: 1.03–1.92 and among women with PCOS who conceived spontaneously was 1.60 (1.18–2.15. No increased risk for other adverse birth outcomes was observed. Conclusions. Women with PCOS were more likely to experience GDM and preterm birth.

    Full Text Available This study aimed to assess whether birth weight is associated with dental caries during the teenage period. In this register-based cohort study, all children of 13 years of age (n = 18,142 who resided in the county of Stockholm, Sweden, in 2000, were included. The cohort was followed until individuals were 19 years of age. Information regarding dental caries was collected from the Public Health Care Administration in Stockholm. Data concerning prenatal and perinatal factors and parental socio-demographic determinants were collected from the Swedish Medical Birth Register and National Registers at Statistics Sweden. The final logistic regression model showed that birth weight ≥4000 g, adjusted for potential confounders, was significantly associated with caries increment (DMFT ≥ 1 (D = decayed, M = missing, F = filled, T = teeth between 13 and 19 age (OR, 1.22; 95% CI = 1.09–1.36. The relatively enhanced risk OR was further increased from 1.22 to 1.43 in subjects with birth weight ≥4600 g. On the contrary, subjects with birth weight <2500 g exhibited a significantly lower risk (OR, 0.67; 95% CI = 0.50–0.89 for exhibiting caries experience (DMFT ≥ 4 at 19 years of age. In conclusion, high birth weight can be regarded as a predictor for dental caries, and especially, birth weight ≥4500 g is a risk factor for caries increment during adolescence.

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

  12. Differential genetic susceptibility to child risk at birth in predicting observed maternal behavior.

    Directory of Open Access Journals (Sweden)

    Keren Fortuna

    Full Text Available This study examined parenting as a function of child medical risks at birth and parental genotype (dopamine D4 receptor; DRD4. Our hypothesis was that the relation between child risks and later maternal sensitivity would depend on the presence/absence of a genetic variant in the mothers, thus revealing a gene by environment interaction (GXE. Risk at birth was defined by combining risk indices of children's gestational age at birth, birth weight, and admission to the neonatal intensive care unit. The DRD4-III 7-repeat allele was chosen as a relevant genotype as it was recently shown to moderate the effect of environmental stress on parental sensitivity. Mothers of 104 twin pairs provided DNA samples and were observed with their children in a laboratory play session when the children were 3.5 years old. Results indicate that higher levels of risk at birth were associated with less sensitive parenting only among mothers carrying the 7-repeat allele, but not among mothers carrying shorter alleles. Moreover, mothers who are carriers of the 7-repeat allele and whose children scored low on the risk index were observed to have the highest levels of sensitivity. These findings provide evidence for the interactive effects of genes and environment (in this study, children born at higher risk on parenting, and are consistent with a genetic differential susceptibility model of parenting by demonstrating that some parents are inherently more susceptible to environmental influences, both good and bad, than are others.

    Objective To evaluate the risk factors for intracranial hemorrhage in premature infants. Methods Cochrane Library, PubMed, ScienceDirect, Chinese Academic Literature Main Database, Chinese Science and Technology Periodi-cal Database, Wanfang Periodicals and Dissertation Database were searched for articles published from January 2000 to December 2012 on the risk factors of intracranial hemorrhage in premature infants, with retrospective retrieval and manual retrieval as supplement. RavMan5.2 provided by Cochrane was used for meta-analysis. Fixed-or random-effects models were selected according to the results of heterogeneity test. Results Nine studies were conifrmed to be eligible. Odds ratio (OR) and 95%conifdence interval (CI) of the risk factors were as follows:gestation age≤32 weeks (OR=3.29, 95%CI=2.76-3.91), birth weight≤1 500g (OR=2.68, 95% CI=2.24-3.20), maternal complications (OR=1.59, 95% CI=1.23-2.06), intrauterine distress or birth asphyxia (OR=2.42, 95% CI=2.06-2.84), mechanical ventilation (OR=3.23, 95% CI=2.55-4.09), metabolic acidosis (OR=2.88, 95%CI=2.04-4.05), use of high concentration of oxygen (OR=2.98, 95%CI=1.63-5.44), prenatal use of dexametha-sone (OR=0.69, 95%CI=0.55-0.86), respiratory distress syndrome (OR=1.57, 95%CI=1.04-2.39). Those differences were all statistically signiifcant. There was no difference in caesarean section (OR=0.99, 95%CI=0.84-1.17), multiparity (OR=1.05, 95%CI=0.79-1.40) and gender (OR=1.25, 95%CI=0.97-1.59). Conclusions The risk factors for intracranial hemorrhage in premature infants are gestation age≤32 weeks, birth weight≤1 500 g, maternal complications, intrauterine distress or birth asphyxia, mechanical ventilation, metabolic acidosis, use of high concentration of oxygen, respiratory distress syndrome, but prenatal use of dexamethasone can reduce the incidence of intracranial hemorrhage in premature infants.%目的综合评价早产儿颅内出血的危险因素。方法检索Cochrane图书馆、PubMed

    Preterm birth (delivery before 37 completed weeks of gestation) is common and rates are increasing. In the past, medical efforts focused on ameliorating the consequences of prematurity rather than preventing its occurrence. This approach resulted in improved neonatal outcomes, but it remains costly in terms of both the suffering of infants and their families and the economic burden on society. Increased understanding of the pathophysiology of preterm labor has altered the approach to this problem, with increased focus on preventive strategies. Primary prevention is a limited strategy which involves public education, smoking cessation, improved nutritional status and avoidance of late preterm births. Secondary prevention focuses on recurrent preterm birth which is the most recognisable risk factor. Widely accepted strategies include cervical cerclage, progesterone and dedicated clinics. However, more research is needed to explore the role of antibiotics and anti-inflammatory treatments in the prevention of this complex problem.

    Life quality of the premature babies after rescuing successfully was gained more attention by perina-tal medical field and society with the more success rate of premature rescue. The brain injury is one of the main factors affecting the long term prognosis of the premature infants. The major risk factors of brain damage include gestational age and birth weight,intrauterine hypoxia and infection,the mode of delivery and whether the resuscitation and later treat-ment skills proper and skilled,and so on. So the key point of preventing the brain injury is avoiding premature delivery and extending the gestational age as much as possible. If the premature delivery could not evitable,the obstetrician should use adrenal cortex hormones before delivery to promote fetal lungs maturition,since the increasing application of cortical hormone prenatally and decreasing using that after birth have been shown good effects on long term prognosis of the nervous system in the preterm infants. It is also confirmed that application of magnesium sulfate prenatally could prevent the premature brain injury. There are still no agreements on the relationship between the delivery modes and the brain injury of extremely low birth weight infants. But prolonging the stage of labor is sure to increase the incidence of intracranial hemorrhage in the premature infants thereby affecting the long term prognosis. After birth,we should imple-ment the correct resuscitation processes by skilled and proper technical methods,in order to decrease the mortality and to improve the long term prognosis.%随着早产儿抢救成功率的日益提高,经抢救成活后的早产儿生命质量愈来愈受到围生医学界和社会的关注,其中脑损伤是影响早产儿远期愈后的主要因素之一。造成脑损伤的危险因素主要有出生时胎龄和体质量、宫内缺氧和感染、分娩方式的选择及后期复苏治疗技术方法是否恰当和熟练等。尽可能地避免早产和尽

    To evaluate the association between adequacy of prenatal care utilization and risk of fetal and neonatal mortality and adverse outcomes. We conducted a population-based cohort study using the Center for Disease Control and Prevention's Linked Birth-Infant Death and Fetal Death data on all deliveries in the United States between 1995 and 2002. Inclusion criteria were singleton births ≥22 weeks of gestation with no known congenital malformation. Inadequate prenatal care was defined according to the Adequacy of Prenatal Care Utilization Index, and its effect on fetal and neonatal death was estimated using unconditional logistic regression analysis adjusting for maternal age, race, education, and other confounding variables. During our 8-year study period, 32,206,417 births occurred, 28,729,765 (89.2%) of which met inclusion criteria. Inadequate prenatal care utilization occurred in 11.2% of expectant mothers, more commonly among women ≤20 years, black non-Hispanic and Hispanic women, and those without high school education. Relative to adequate care, inadequate care was associated with increased risk of prematurity 3.75 (3.73 to 3.77), stillbirth 1.94 (1.89 to 1.99), early neonatal dearth 2.03 (1.97 to 2.09), late neonatal death 1.67 (1.59 to 1.76), and infant death 1.79 (1.76 to 1.82). Risk of prematurity, stillbirth, early and late neonatal death, and infant death increased linearly with decreasing care. Given the population effect of this association, public health initiatives should target program expansion to ensure timely and adequate access, particularly for women ≤20 years, Black non-Hispanic and Hispanic women, and those without high school education.

    Several studies show that maternal and neonatal/infant mortality risks increase with younger and older maternal age (34 years), high parity (birth order >3), and short birth intervals (Oaxaca decomposition technique, we then examine the contributions of family planning program, economic development (GDP per capita), and educational improvement (secondary school completion rate) on the progress of MCPR in order to link the net contribution of family planning program to the reduction of high-risk births mediated through contraceptive use. Countries that had the fastest progress in improving MCPR experienced the greatest declines in high-risk births due to short birth intervals (3), and older maternal age (>35 years). Births among younger women <18 years, however, did not decline significantly during this period. The decomposition analysis suggests that 63% of the increase in MCPR was due to family planning program efforts, 21% due to economic development, and 17% due to social advancement through women's education. Improvement in MCPR, predominately due to family planning programs, is a major driver of the decline in the burden of high-risk births due to high parity, shorter birth intervals, and older maternal age in developing countries. The lack of progress in the decline of births in younger women <18 years of age underscores the need for more attention to ensure that quality contraceptive methods are available to adolescent women in order to delay first births. This study substantiates the significance of family planning programming as a major health intervention for preventing high-risk births and associated maternal and child mortality, but it highlights the need for concerted efforts to strengthen service provision for adolescents.

    Full Text Available Abstract Background Birth defects, which are the major cause of infant mortality and a leading cause of disability, refer to "Any anomaly, functional or structural, that presents in infancy or later in life and is caused by events preceding birth, whether inherited, or acquired (ICBDMS". However, the risk factors associated with heredity and/or environment are very difficult to filter out accurately. This study selected an area with the highest ratio of neural-tube birth defect (NTBD occurrences worldwide to identify the scale of environmental risk factors for birth defects using exploratory spatial data analysis methods. Methods By birth defect registers based on hospital records and investigation in villages, the number of birth defects cases within a four-year period was acquired and classified by organ system. The neural-tube birth defect ratio was calculated according to the number of births planned for each village in the study area, as the family planning policy is strictly adhered to in China. The Bayesian modeling method was used to estimate the ratio in order to remove the dependence of variance caused by different populations in each village. A recently developed statistical spatial method for detecting hotspots, Getis's 7, was used to detect the high-risk regions for neural-tube birth defects in the study area. Results After the Bayesian modeling method was used to calculate the ratio of neural-tube birth defects occurrences, Getis's statistics method was used in different distance scales. Two typical clustering phenomena were present in the study area. One was related to socioeconomic activities, and the other was related to soil type distributions. Conclusion The fact that there were two typical hotspot clustering phenomena provides evidence that the risk for neural-tube birth defect exists on two different scales (a socioeconomic scale at 6.84 km and a soil type scale at 22.8 km for the area studied. Although our study has limited

    Preterm premature rupture of membranes (PPROM) occurs in 3% of pregnancies and is responsible for 30% of preterm births. The management is discussed between active and expectant management. French recommendations let open both possibilities. The risks described in the case of PPROM are those of prematurity, maternofetal infection, acute procidence of the umbilical cord and abruptio placentae. Before 32 weeks of gestation (WG) and even 34 WG, a prolongation of one week of gestational age significantly decreases neonatal mortality and morbidity. Therefore, most of the authors choose expectant management in case of PPROM. Between 34 and 37 WG, the risk of rare severe morbidity associated with prematurity has to be balanced with risks of an acute maternofetal infection and of abruptio placentae. Further randomized trials are required to choose a type of management with a sufficient level of evidence.

    Objectives The purpose of this study is to evaluate the prevalence, impact, and interaction of short interpregnancy interval (IPI), pre-pregnancy body mass index (BMI) category, and pregnancy weight gain (PWG) on the rate of preterm birth. Methods This is a population-based retrospective cohort study using vital statistics birth records from 2006 to 2011 in OH, US, analyzing singleton live births to multiparous mothers with recorded IPI (n = 393,441). Preterm birth rate at preterm birth rate of 7.6 % for this group. Short IPIs of preterm birth rate to 12.9 and 10.4 %, respectively. Low PWG compared to IOM recommendations for pre-pregnancy BMI class was also associated with increased preterm birth rate of 13.2 % for all BMI classes combined. However, the highest rate of preterm birth of 25.2 % occurred in underweight women with short IPI and inadequate weight gain with adjOR 3.44 (95 % CI 2.80, 4.23). The fraction of preterm births observed in this cohort that can be attributed to short IPIs is 5.9 %, long IPIs is 8.3 %, inadequate PWG is 7.5 %, and low pre-pregnancy BMI is 2.2 %. Conclusions Our analysis indicates that a significant proportion of preterm births in Ohio are associated with potentially modifiable risk factors. These data suggest public health initiatives focused on preterm birth prevention could include counseling and interventions to optimize preconception health and prenatal nutrition.

    Lack of specific monitoring protocols hinders the knowledge of the impact of late prematurity on delayed psychomotor development. The objective of this study is to evaluate this at 48 months and compare it with those born at term. A retrospective cohort study was conducted on 90 late preterm (PT) and 89 term (AT) healthy children at 48 months, assessed by the Ages & Stages Questionnaires® (ASQ-3). Continuous variables described using mean and standard deviation compared with the t Student t test for independent samples. The categorical variables were described as frequencies and proportions, compared with the Chi-square test of independence. A cut-off was determined for the total score of ASQ-3 able to discriminate the risk of developmental deficit by a ROC analysis. A step-wise logistic regression model identified the associated risk factors. The mean scores for each domain and overall ASQ-3 score showed no differences between groups. However, when analyzing the probability density for the ASQ-3 total score of ≤251 points, 15 PT (16.6%) and 4 AT (4.5%) showed risk of psychomotor deficits, and late prematurity and lack of breastfeeding were significantly associated factors. There is an increased prevalence of risk of development deficit in the PT, which justifies considering this population at risk and establishing effective monitoring programs. It should be further investigated whether this risk corresponds to the entire population, or if there are biological factors or perinatal history that makes them more vulnerable.

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

    Little is known about the risk of non-recurrent adverse birth outcomes. To evaluate the risk of stillbirth, preterm birth (PTB), and small for gestational age (SGA) as a proxy for fetal growth restriction (FGR) following exposure to one or more of these factors in a previous birth. We searched MEDLINE, EMBASE, Maternity and Infant Care, and Global Health from inception to 30 November 2016. Studies were included if they investigated the association between stillbirth, PTB, or SGA (as a proxy for FGR) in two subsequent births. Meta-analysis and pooled association presented as odds ratios (ORs) and adjusted odds ratios (aORs). Of the 3399 studies identified, 17 met the inclusion criteria. A PTB or SGA (as a proxy for FGR) infant increased the risk of subsequent stillbirth ((pooled OR 1.70; 95% confidence interval, 95% CI, 1.34-2.16) and (pooled OR 1.98; 95% CI 1.70-2.31), respectively). A combination of exposures, such as a preterm SGA (as a proxy for FGR) birth, doubled the risk of subsequent stillbirth (pooled OR 4.47; 95% CI 2.58-7.76). The risk of stillbirth also varied with prematurity, increasing three-fold following PTB term health problems. The effect of having a stillbirth, preterm birth, or small-for-gestational-age infant in a previous pregnancy on future pregnancy health has not been summarised. We identified 3399 studies of outcomes of previous pregnancies, and 17 were summarised by our study. What were the main findings? The outcome of the previous pregnancy influenced the risk of poor outcomes in the next pregnancy. Babies born to mothers who had a previous preterm birth or small-for-gestational-age birth were more likely to be stillborn. The smaller and the more preterm the previous baby, the higher the risk of stillbirth in the following pregnancy. The risk of stillbirth in the following pregnancy was doubled if the previous baby was born both preterm and small for gestational age. Babies born to mothers who had a previous stillbirth were more likely

    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 BACKGROUND: Preterm birth, defined as birth occurring before 37 weeks gestation, is one of the most significant contributors to neonatal mortality and morbidity, with long-term adverse consequences for health, and cognitive outcome. OBJECTIVE: The aim of the present study was to identify risk factors of preterm birth (≤36+6 weeks gestation among singleton births and to quantify the contribution of risk factors to socioeconomic disparities in preterm birth. METHODS: A retrospective population-based case-control study using data derived from the Finnish Medical Birth Register. A total population of singleton births in Finland from 1987-2010 (n = 1,390,742 was reviewed. RESULTS: Among all singleton births (n = 1,390,742, 4.6% (n = 63,340 were preterm (<37 weeks, of which 0.3% (n = 4,452 were classed as extremely preterm, 0.4% (n = 6,213 very preterm and 3.8% (n = 54,177 moderately preterm. Smoking alone explained up to 33% of the variation in extremely, very and moderately preterm birth incidence between high and the low socioeconomic status (SES groups. Reproductive risk factors (placental abruption, placenta previa, major congenital anomaly, amniocentesis, chorionic villus biopsy, anemia, stillbirth, small for gestational age (SGA and fetal sex altogether explained 7.7-25.0% of the variation in preterm birth between SES groups. CONCLUSIONS: Smoking explained about one third of the variation in preterm birth groups between SES groups whereas the contribution of reproductive risk factors including placental abruption, placenta previa, major congenital anomaly, amniocentesis, chorionic villus biopsy, anemia, stillbirth, SGA and fetal sex was up to one fourth.

    Full Text Available There are disagreements among researchers about the association between vitamin D deficiency during pregnancy and preterm birth (PTB. Therefore, we conducted a meta-analysis of observational studies to evaluate this association. We performed a systematic literature search of PubMed, MEDLINE and the Cochrane Library through August 2015 with the following keywords: “vitamin D” or “cholecalciferol” or “25-hydroxyvitamin D” or “25(OHD” in combination with “premature birth” or “preterm birth” or “PTB” or “preterm delivery” or “PTD” or “prematurity”. Our meta-analysis of 10 studies included 10,098 participants and found that pregnant women with vitamin D deficiency (maternal serum 25 (OH D levels < 20 ng/mL experienced a significantly increased risk of PTB (odds ratio (OR = 1.29, 95% confidence intervals(CI: 1.16, 1.45 with low heterogeneity (I2 = 25%, p = 0.21. Sensitivity analysis showed that exclusion of any single study did not materially alter the overall combined effect. In the subgroup analyses, we found that heterogeneity was obvious in prospective cohort studies (I2 = 60%, p = 0.06. In conclusion, pregnant women with vitamin D deficiency during pregnancy have an increasing risk of PTB.

    The main objective of this study was to estimate the contributing role of maternal, child, and organizational risk factors in perinatal mortality by calculating their population attributable risks (PAR). The primary dataset comprised 1,020,749 singleton hospital births from ≥22 weeks' gestation (The Netherlands Perinatal Registry 2000-2008). PARs for single and grouped risk factors were estimated in four stages: (1) creating a duplicate dataset for each PAR analysis in which risk factors of interest were set to the most favorable value (e.g., all women assigned 'Western' for PAR calculation of ethnicity); (2) in the primary dataset an elaborate multilevel logistic regression model was fitted from which (3) the obtained coefficients were used to predict perinatal mortality in each duplicate dataset; (4) PARs were then estimated as the proportional change of predicted- compared to observed perinatal mortality. Additionally, PARs for grouped risk factors were estimated by using sequential values in two orders: after PAR estimation of grouped maternal risk factors, the resulting PARs for grouped child, and grouped organizational factors were estimated, and vice versa. The combined PAR of maternal, child and organizational factors is 94.4 %, i.e., when all factors are set to the most favorable value perinatal mortality is expected to be reduced with 94.4 %. Depending on the order of analysis, the PAR of maternal risk factors varies from 1.4 to 13.1 %, and for child- and organizational factors 58.7-74.0 and 7.3-34.3 %, respectively. In conclusion, the PAR of maternal-, child- and organizational factors combined is 94.4 %. Optimization of organizational factors may achieve a 34.3 % decrease in perinatal mortality.

    Food insecurity represents a lack of access to enough food to meet basic needs. We hypothesized that food insecurity may increase birth defect risks, because it is an indicator of increased stress or compromised nutrition, which are both implicated in birth defect etiologies. This study used population-based case-control data. Included in the analysis were 1,189 case mothers and 695 control mothers who were interviewed by telephone. We calculated a food insecurity score as the number of affir...

    Evidence suggests that a proportion of women report posttraumatic stress disorder (PTSD) after childbirth, with between 1 and 3% of women developing the disorder as a direct result of birth (Alcorn, O'Donovan, Patrick, Creedy, & Devilly). A range of factors are associated with postpartum PTSD, including prepartum, birth and postpartum factors. This meta-analysis synthesizes research on posttraumatic stress symptoms after childbirth in order to identify key vulnerability and risk factors. ...

    Full Text Available BACKGROUND: Low plasma folate concentrations in pregnancy are associated with preterm birth. Here we show an association between preconceptional folate supplementation and the risk of spontaneous preterm birth. METHODS AND FINDINGS: In a cohort of 34,480 low-risk singleton pregnancies enrolled in a study of aneuploidy risk, preconceptional folate supplementation was prospectively recorded in the first trimester of pregnancy. Duration of pregnancy was estimated based on first trimester ultrasound examination. Natural length of pregnancy was defined as gestational age at delivery in pregnancies with no medical or obstetrical complications that may have constituted an indication for delivery. Spontaneous preterm birth was defined as duration of pregnancy between 20 and 37 wk without those complications. The association between preconceptional folate supplementation and the risk of spontaneous preterm birth was evaluated using survival analysis. Comparing to no supplementation, preconceptional folate supplementation for 1 y or longer was associated with a 70% decrease in the risk of spontaneous preterm delivery between 20 and 28 wk (41 [0.27%] versus 4 [0.04%] spontaneous preterm births, respectively; HR 0.22, 95% confidence interval [CI] 0.08-0.61, p = 0.004 and a 50% decrease in the risk of spontaneous preterm delivery between 28 and 32 wk (58 [0.38%] versus 12 [0.18%] preterm birth, respectively; HR 0.45, 95% CI 0.24-0.83, p = 0.010. Adjustment for maternal characteristics age, race, body mass index, education, marital status, smoking, parity, and history of prior preterm birth did not have a material effect on the association between folate supplementation for 1 y or longer and spontaneous preterm birth between 20 and 28, and 28 to 32 wk (adjusted HR 0.31, 95% CI 0.11-0.90, p = 0.031 and 0.53, 0.28-0.99, p = 0.046, respectively.

    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

    Cesarean birth has been associated with higher risk of obesity in offspring, but previous studies have focused primarily on childhood obesity and have been hampered by limited control for confounders. To investigate the association between cesarean birth and risk of obesity in offspring. A prospective cohort study was conducted from September 1, 1996, to December 31, 2012, among participants of the Growing Up Today Study, including 22 068 offspring born to 15 271 women, followed up via questionnaire from ages 9 to 14 through ages 20 to 28 years. Data analysis was conducted from October 10, 2015, to June 14, 2016. Birth by cesarean delivery. Risk of obesity based on International Obesity Task Force or World Health Organization body mass index cutoffs, depending on age. Secondary outcomes included risks of obesity associated with changes in mode of delivery and differences in risk between siblings whose modes of birth were discordant. Of the 22 068 offspring (20 950 white; 9359 male and 12 709 female), 4921 individuals (22.3%) were born by cesarean delivery. The cumulative risk of obesity through the end of follow-up was 13% among all participants. The adjusted risk ratio for obesity among offspring delivered via cesarean birth vs those delivered via vaginal birth was 1.15 (95% CI, 1.06-1.26; P = .002). This association was stronger among women without known indications for cesarean delivery (adjusted risk ratio, 1.30; 95% CI, 1.09-1.54; P = .004). Offspring delivered via vaginal birth among women who had undergone a previous cesarean delivery had a 31% (95% CI, 17%-47%) lower risk of obesity compared with those born to women with repeated cesarean deliveries. In within-family analysis, individuals born by cesarean delivery had 64% (8%-148%) higher odds of obesity than did their siblings born via vaginal delivery. Cesarean birth was associated with offspring obesity after accounting for major confounding factors. Although additional research is

    Full Text Available Abstract Background Preterm birth is a complex disease with etiologic influences from a variety of social, environmental, hormonal, genetic, and other factors. The purpose of this study was to utilize a large population-based birth registry to estimate the independent effect of county-level poverty on preterm birth risk. To accomplish this, we used a multilevel logistic regression approach to account for multiple co-existent individual-level variables and county-level poverty rate. Methods Population-based study utilizing Missouri's birth certificate database (1989–1997. We conducted a multilevel logistic regression analysis to estimate the effect of county-level poverty on PTB risk. Of 634,994 births nested within 115 counties in Missouri, two levels were considered. Individual-level variables included demographics factors, prenatal care, health-related behavioral risk factors, and medical risk factors. The area-level variable included the percentage of the population within each county living below the poverty line (US census data, 1990. Counties were divided into quartiles of poverty; the first quartile (lowest rate of poverty was the reference group. Results PTB th quartile (4.9%, p adjOR 1.18 (95% CI 1.03, 1.35, with a similar effect at earlier gestational ages (adjOR 1.27 (95% CI 1.06, 1.52. Conclusion Women residing in socioeconomically deprived areas are at increased risk of preterm birth, above other underlying risk factors. Although the risk increase is modest, it affects a large number of pregnancies.

    Full Text Available BACKGROUND: Preterm birth, the birth of an infant prior to 37 completed weeks of gestation, is the leading cause of perinatal morbidity and mortality. Preterm infants are at greater risk of respiratory, gastrointestinal and neurological diseases. Despite significant research in developed countries, little is known about the causes of preterm birth in many developing countries, especially China. This study investigates the association between sciodemographic data, obstetric risk factor, and preterm birth in five Maternal and Child Health hospitals in Beijing, China. METHODS AND FINDINGS: A case-control study was conducted on 1391 women with preterm birth (case group and 1391 women with term delivery (control group, who were interviewed within 48 hours of delivery. Sixteen potential factors were investigated and statistical analysis was performed by univariate analysis and logistic regression analysis. Univariate analysis showed that 14 of the 16 factors were associated with preterm birth. Inter-pregnancy interval and inherited diseases were not risk factors. Logistic regression analysis showed that obesity (odds ratio (OR = 3.030, 95% confidence interval (CI 1.166-7.869, stressful life events (OR = 5.535, 95%CI 2.315-13.231, sexual activity (OR = 1.674, 95%CI 1.279-2.191, placenta previa (OR 13.577, 95%CI 2.563-71.912, gestational diabetes mellitus (OR = 3.441, 95%CI1.694-6.991, hypertensive disorder complicating pregnancy (OR = 6.034, 95%CI = 3.401-10.704, history of preterm birth (OR = 20.888, 95%CI 2.519-173.218 and reproductive abnormalities (OR = 3.049, 95%CI 1.010-9.206 were independent risk factors. Women who lived in towns and cities (OR = 0.603, 95%CI 0.430-0.846, had a balanced diet (OR = 0.533, 95%CI 0.421-0.675 and had a record of prenatal care (OR = 0.261, 95%CI 0.134-0.510 were less likely to have preterm birth.

    To explore the risks of moderately low (MLBW) and very low birthweight (VLBW) among Asian-American women, with particular attention to adolescent mothers. Data from birth certificates on 28,477 Asian women who gave birth in New York City between 1987 and 1993 were used to calculate percentages of MLBW and VLBW, and logistic regression analysis was used to estimate odds ratios for maternal age, country of origin, and other risk factors. Adolescents had elevated risks for both MLBW and VLBW, and most of this risk was attributed to the high prevalence of maternal sociodemographic risk factors among adolescents, as compared to older women. A significantly elevated risk of VLBW was found for teens who were born in the United States, suggesting a worrisome picture for second-generation Asian Americans.

    Unwarranted variations in care are defined as differences in utilization of health care resources that cannot be explained by patient risk factors, standards of evidence-based medicine, or patient preferences. Also known as nonmedical determinants of variation, differences in health care utilization across the United States have been well documented in the literature during the past 40 years. The purpose of the literature review is to summarize the state of the science related to the nonmedical determinants of variation in cesarean birth among low-risk childbearing women, defined within national quality standards as nulliparous women with term, singleton pregnancies in the vertex presentation. A literature search was performed using the electronic databases PubMed, CINAHL, Ovid MEDLINE, Google Scholar, Cochrane Database of Systematic Reviews, and ProQuest Dissertation Database. Articles published in English, with full text available, including birth in the United States after 1995, are included in the analysis. Nine studies met criteria for inclusion. Forty-four states are represented within the data, with Arizona, California, Massachusetts, New Jersey, and New York being the subject of more than one of the publications analyzed. This literature review includes more than one million births, in at least 44 states between 1996 through 2009, revealing significant unwarranted variation in cesarean birth. Nonmedical determinants of variation, such as access to resources, hospital characteristics, payer source, and provider practice styles, are identified as independent predictors of increased cesarean utilization in more than half of the studies reviewed. In all studies reviewed, women of low medical risk demonstrate susceptibility to unwarranted variation in the use of cesarean birth. Continued emphasis on the specific needs of low-risk childbearing women is necessary to decrease unwarranted variation in the use of cesarean birth in the United States. Specific

    Full Text Available Oxytocin is crucially involved in the onset and maintenance of labor. We investigated the association between oxytocin receptor gene polymorphisms and preterm birth. The presence of four common oxytocin receptor gene polymorphisms (rs2254298, rs53576, rs2228485 and rs237911 was evaluated in one hundred women with preterm birth and one hundred healthy women using restriction fragment length polymorphism genotyping. No association was found between the presence of any individual oxytocin receptor gene polymorphism and preterm birth. In haplotype analysis, the haplotype combination of rs2254298 A allele, rs2228485 C allele and rs237911 G allele was found to be significantly associated with an increased risk of preterm birth (OR = 3.2 [CI 1.04–9.8], p = 0.043. In conclusion our findings suggest that a combination of three oxytocin receptor gene polymorphisms is associated with an increased risk for preterm birth. We propose further studies investigating the role of oxytocin receptor gene polymorphisms and preterm birth.

    We examined the association of occupational exposure to handling cytotoxic drugs at work with risk of birth defects among a cohort of female veterinarians. This study is a follow up survey of 321 female participants (633 pregnancies) who participated in the Health Risks of Australian Veterinarian project. Data on pregnancies and exposure during each pregnancy was obtained by self-administered mailed questionnaire. Female veterinarians handling cytotoxic drugs during their pregnancy had a two-fold increased risk of birth defects in their offspring (RR = 2.08, 95% CI (1.05-4.15)). Results were consistent in subgroup analysis of those who graduated during the period of 1961 to 1980 (RR = 5.04, 95% CI (1.81, 14.03) and in those working specifically in small and large animal practice. There was no increased risk in the subgroup that graduated after 1980. Women with unplanned pregnancies were more likely to handle cytotoxic drugs on a daily basis (RR = 1.86, 95% CI, 1.00-3.48) and had a higher increased risk of birth defects than those who planned their pregnancies in recent graduates and in those who worked specifically in small animal practice (RR = 2.53, 95% CI, 1.18-5.42). This study suggests that the adverse effects of handling cytotoxic drugs in pregnant women may include an increased risk of birth defects. Pregnancy intention status is an important health behavior and should be considered in prenatal programs.

    Full Text Available We examined the effects of prematurity (37 weeks of gestation and low birthweight (2500 g on mental health outcomes among US children aged 2–17 years. The 2011-2012 National Survey of Children’s Health ( = 95,677 was used to estimate prevalence of parent-reported mental health problems in children. Prevalence of mental disorders was 22.9% among children born prematurely, 28.7% among very-low-birth-weight (1500 g children, and 18.9% among moderately low-birth-weight (1500–2499 g children, compared with 15.5% in the general child population. Compared to those born full term, children born prematurely had 61% higher adjusted odds of serious emotional/behavioral problems, 33% higher odds of depression, and 58% higher odds of anxiety. Children born prematurely had 2.3 times higher odds of autism/ASD, 2.9 times higher odds of development delay, and 2.7 times higher odds of intellectual disability than term children. Very-low-birth-weight children had 3.2 times higher odds of autism/ASD, 1.7 times higher odds of ADD/ADHD, 5.4 times higher odds of development delay, and 4.4 times higher odds of intellectual disability than normal-birth-weight children. Social factors were significant predictors of mental disorders in both premature/low-birth-weight and term/normal-birth-weight children. Neurodevelopmental conditions accounted for the relationship between prematurity and depression/anxiety/conduct problems. Prematurity and low birthweight are significant risk factors for mental health problems among children.

    There is strong evidence that low and high birth weight due to in-utero programming results in elevated risk for adult diseases, though less research has been performed examining the influence of birth weight and physical disability later in life. Baseline data from 76,055 postmenopausal women in the Women's Health Initiative, a large multi-ethnic cohort, were used to examine the association between self-reported birth weight category (education, race/ethnicity, body mass index, and a comorbidity score. Unadjusted models indicate that women born in the lowest and highest birth weight categories have significantly lower physical functioning scores as compared to women born in the normal weight category (β = -2.22, p disability.

    There is a well-documented reduction in endometrial cancer risk with combined oral contraceptive (COC) use. COC use before the first full-term pregnancy may affect breast cancer risk for decades, but this relationship has not been investigated in endometrial cancer. We investigated the risk for endometrial cancer with COC use before the first full-term pregnancy. Cases (n = 524) from a population-based cancer registry and age-matched controls (n = 1,032) were recruited between 2002 and 2006 in Alberta, Canada. Participants completed an in-person interview and provided detailed information on exogenous hormone use and other risk factors. Risk reductions in endometrial cancer with COC use over the premenopausal years were consistent with the published literature. We also found evidence of a long-term, significant risk reduction in parous women with COC use before the first full-term pregnancy. Among parous women, ≥5 years of COC use before a first full-term pregnancy was associated with a significant reduction in risk [adjusted OR, 0.42; 95% confidence interval (CI), 0.25-0.72], even if this exposure was a woman's only use of COCs (adjusted OR, 0.35; 95% CI, 0.18-0.68). Further understanding of the long-term effects of COC use may help guide the timing of chemoprevention efforts via COCs.

  1. Preclinical screening for retinopathy of prematurity risk using IGF1 levels at 3 weeks post-partum.

    Alejandro Pérez-Muñuzuri

    Full Text Available Following current recommendations for preventing retinopathy of prematurity (ROP involves screening a large number of patients. We performed a prospective study to establish a useful screening system for ROP prediction and we have determined that measuring serum levels of IGF1 at week three and the presence of sepsis have a high predictive value for the subsequent development of ROP. A total of 145 premature newborn, with birthweight <1500 g and/or <32 weeks gestational age, were enrolled. 26.9% of them showed some form of retinopathy. A significant association was found between the development of retinopathy and each of the following variables: early gestational age, low birthweight, requiring mechanical ventilation, oxygen treatment, intracranial haemorrhage, sepsis during the first three weeks, bronchopulmonary dysplasia, the need for erythrocyte transfusion, erythropoietin treatment, and low levels of serum IGF1 in the third week. A multiple logistic regression analysis was used to obtain curves for the probability of developing ROP, based on the main factors linked with ROP, namely serum levels of IGF1 and presence of sepsis. Such preclinical screening has the ability to identify patients with high-risk of developing retinopathy and should lead to better prediction for ROP, while at the same time optimising the use of clinical resources, both human and material.

    Risk factors were included NVD (difficult vaginal delivery, high gestation age, and low Apgar score at first minute of life, shoulder dystocia, vacuum and birth at night. Conclusion: The present study revealed that the incidence of birth injuries in this area is high. Considering the serious complications of birth injuries and hypoxic-ischemic encephalopathy with no treatment for some cases, it seems that using the preventing methods to reduce the prevalence of birth injuries is nessesary

    Full Text Available We investigated serum folic acid (FA levels in patients with erectile dysfunction (ED and/or premature ejaculation (PE. Fasting serum samples were obtained from 42 patients with ED, 36 with PE, 25 ED patients with PE, and 30 healthy men; the mean intravaginal ejaculation latency time (IELT was measured during a 4 weeks baseline period. Levels of sex hormones (follicle-stimulating hormone, luteinizing hormone, total testosterone, homocysteine (Hcys, and FA were measured using chemiluminescent immunoassays. The sexual functions of PE patients and normal control men were evaluated using the Chinese Index of Premature Ejaculation (CIPE. The abridged International Index of Erectile Function-5 (IIEF-5 questionnaire was used to gauge erectile quality for ED patients and for normal controls. Serum FA concentrations were lower in ED (7.61 ± 3.97 ng ml -1, PE (9.37 ± 3.40 ng ml -1, and ED/PE (8.84 ± 4.28 ng ml -1 patients than in healthy men (12.23 ± 5.76 ng ml -1 , P 0.05. There were positive correlations between serum FA concentrations and CIPE scores (r = 0.530, P < 0.01, IIEF-5 scores (r = 0.589, P < 0.01, and IELT (r = 0.445, P < 0.01; negative correlations with Hcys concentrations (r = −0.487, P < 0.01 were found in all participants. These findings showed a strong relationship between serum FA levels and sexual dysfunction, possibly due to an effect of FA on the metabolism of nitric oxide, Hcys, and 5-hydroxytryptamine.

    Objectives: The present study was undertaken to study the maternal risk factors for preterm birth (PTB) and low birth weight (LBW) with a special emphasis on assessing the proportions of maternal genitourinary and periodontal infections among Indian women and their association with adverse pregnancy outcomes. Methods: A hospital-based prospective study comprising 790 pregnant women visiting the obstetrics clinic for a routine antenatal check-up was undertaken. Once recruited, all study participants underwent clinical and microbiological investigations for genitourinary infections followed by a dental check-up for the presence of periodontitis. The study participants were followed up until their delivery to record the pregnancy outcomes. Infectious and non-infectious risk factors for PTB and LBW were assessed using univariate and multivariate Cox regression analysis. Independent risk factors for PTB and LBW were reported in terms of adjusted relative risk (ARR) with the 95% confidence interval (CI). Results: Rates of PTB and LBW in the study population were 7.6% and 11.4%, respectively. Previous preterm delivery (ARR, 5.37; 95% CI, 1.5 to 19.1), periodontitis (ARR, 2.39; 95% CI, 1.1 to 4.9), Oligohydramnios (ARR, 5.23; 95% CI, 2.4 to 11.5), presence of Nugent’s intermediate vaginal flora (ARR, 2.75; 95% CI, 1.4 to 5.1), gestational diabetes mellitus (ARR, 2.91; 95% CI, 1.0 to 8.3), and maternal height <1.50 m (ARR, 2.21; 95% CI, 1.1 to 4.1) were risk factors for PTB, while periodontitis (ARR, 3.38; 95% CI, 1.6 to 6.9), gestational hypertension (ARR, 3.70; 95% CI, 1.3 to 10.8), maternal height <1.50 m (ARR, 2.66; 95% CI, 1.3 to 5.1) and genital infection during later stages of pregnancy (ARR, 2.79; 95% CI, 1.2 to 6.1) were independent risk factors for LBW. Conclusions: Our study findings underscore the need to consider screening for potential genitourinary and periodontal infections during routine antenatal care in developing countries. PMID:27255075

    Sport climbing is a popular recreational sport with an increasing proportion of female athletes. International recommendations emphasize the physical and mental benefits of regular sport activity during any uncomplicated pregnancy. In this context, sport climbing is associated with a high risk potential.The aim of this study was to examine if there is a higher risk for preterm birth in active climbing athletes.Original manuscript.A retrospective self-report online survey in the German language collected data between September 2012 and November 2013. In addition to anthropometric and demographic data, data on climbing experience, preferred climbing discipline, skill level and changes of climbing habits during pregnancy, known risk factors for preterm birth and information on delivery and the newborn were requested. The rate of preterm birth of the survey was tested with Fisher's exact test with information from the German Federal Statistical Office.Sample size was 32. 72% had a university degree, 81% were primiparous, all were singleton pregnancies. A 33(rd) questionnaire was excluded because of described preeclampsia. Age ranged between 21 and 39 years, climbing experience before pregnancy between 2 and 24 years, and skill level before pregnancy between 4 and 7 on the UIAA scale (International Climbing and Mountaineering Federation). Half of the women climbed until the 36(th) week and 90% adjusted their climbing habits mostly by reducing climbing difficulty and doing more top roping. 2 preterm births in the 36(th) week of gestation were found (2 from 15, p=0.36). According to the data from the German Federal Statistical Office, 8.9% births in the year 2013 in Germany were preterm.This is the first study investigating the risk of preterm birth in recreational sport climbing athletes. No significantly higher proportion of preterm birth could be found. Limitations are small sample size and high social status of participants. What is known about the subject: Sport

    1997-07-01

    This study is a multifactorial analysis of the risk factors for low birthweight in a group of newborns in an urban area of Brazil. A total of 1023 infants born in four maternity units in Salvador, Bahia, between July 1987 and February 1988 were included in the study. The sources of information were clinical histories and interviews with the mothers in the maternity units. The analysis was by means of logistic regression. In the final model the risk factors were the following: maternal age less than 21 years or more than 35; gestational age less than 38 weeks; unfavorable outcome of an earlier pregnancy; interval of 12 months or less since prior birth; tobacco smoking; and hypertension. The population attributable risk values for the risk factors included in the final model are presented. These factors should be used to identify pregnant women at high risk of giving birth to a low-birthweight baby, in order to provide them with more prenatal care.

    Full Text Available Purpose. To examine the association between previous preterm birth and the risk of stillbirth. Methods. This population-based retrospective cohort study analyzed live births and stillbirth records in Missouri (1989–1997. The main outcome of interest was stillbirth occurrence while the exposures were prior preterm birth. Adjusted odds ratios and 95% confidence intervals were computed using logistic regression. Results. Women who had a previous preterm birth have 63% increased odds of stillbirth in singleton pregnancies and 75% increased odds in twins as compared to those who did not have a preterm birth in a prior pregnancy (AOR = 1.63, 95% CI = 1.41–1.88 and AOR = 1.75, 95% CI = 1.20–2.56, respectively. The most significant risk factor for stillbirth in singleton pregnancies was uterine bleeding (AOR = 5.89, 95% CI = 5.13–6.76. In twin pregnancies, it was the condition hydramnios/oligohydramnios (AOR = 4.72, 95% CI = 3.70–6.02. Eclampsia was associated with a heightened risk of stillbirth in singletons (AOR = 2.45, 95% CI = 1.41–4.12, but not in twins (AOR = 0.96, 95% CI = 0.13–7.00. Black mothers were more likely than white to experience stillbirth (AOR = 2.10, 95% CI = 1.99–2.22 for singletons and AOR = 1.51, 95% CI = 1.27–1.79 for twins. Conclusion. Stillbirth is a vital public health issue and its etiology is not well understood. Previous history of preterm birth was found to be associated with future stillbirth. Targeted early medical and obstetric care and interventions among women with preterm birth history may potentially reduce the likelihood of stillbirth.

    Full Text Available Abstract Background A significant number of Canadian rural communities offer local maternity services in the absence of caesarean section back-up to parturient residents. These communities are witnessing a high outflow of women leaving to give birth in larger centres to ensure immediate access to the procedure. A minority of women choose to stay in their home communities to give birth in the absence of such access. In this instance, decision-making criteria and conceptions of risk between physicians and parturient women may not align due to the privileging of different risk factors. Methods In-depth qualitative interviews and focus groups with 27 care providers and 43 women from 3 rural communities in B.C. Results When birth was planned locally, physicians expressed an awareness and acceptance of the clinical risk incurred. Likewise, when birth was planned outside the local community, most parturient women expressed an awareness and acceptance of the social risk incurred due to leaving the community. Conclusions The tensions created by these contrasting approaches relate to underlying values and beliefs. As such, an awareness can address the impasse and work to provide a resolution to the competing prioritizations of risk.

    2015-11-01

    Full Text Available Background: Family planning expansion has been identified as an impetus to harnessing Nigeria's demographic dividend. However, there is a need for data to address pockets of inequality and to better understand cultural and social factors affecting contraceptive use and health benefits. This paper contributes to addressing these needs by providing evidence on the trends and sub-national patterns of modern contraceptive prevalence in Nigeria and the association between contraceptive use and high-risk births in Nigeria. Design: The study utilised women's data from the last three Demographic and Health Surveys (2003, 2008, and 2013 in Nigeria. The analysis involved descriptive, bivariate, and multivariate analyses. The multivariate analyses were performed to examine the relationship between high-risk births and contraceptive use. Associations were examined using Poisson regression. Results: Findings showed that respondents in avoidable high-risk birth categories were less likely to use contraceptives compared to those at no risk [rate ratio 0.82, confidence interval: 0.76–0.89, p<0.001]. Education and wealth index consistently predicted significant differences in contraceptive use across the models. Conclusions: The results of this study suggest that women in the high-risk birth categories were significantly less likely to use a modern method of contraception relative to those categorised as having no risk. However, there are huge sub-national variations at regional and state levels in contraceptive prevalence and subsequent high-risk births. These results further strengthen evidence-based justification for increased investments in family planning programmes at the state and regional levels, particularly regions and states with high unmet needs for family planning.

    Infectious etiologies have been hypothesized for Hodgkin and non-Hodgkin lymphoma (HL and NHL) in early life, but findings to date for specific lymphomas and periods of susceptibility are conflicting. We conducted the first national cohort study to examine whether season of birth, a proxy for infectious exposures in the first few months of life, is associated with HL or NHL in childhood through young adulthood. A total of 3,571,574 persons born in Sweden in 1973-2008 were followed up through 2009 to examine the association between season of birth and incidence of HL (943 cases) or NHL (936 cases). We found a sinusoidal pattern in NHL risk by season of birth (p = 0.04), with peak risk occurring among birthdates in April. Relative to persons born in fall (September-November), odds ratios for NHL by season of birth were 1.25 [95% confidence interval (CI), 1.04-1.50; p = 0.02] for spring (March-May), 1.22 (95% CI, 1.01-1.48; p = 0.04) for summer (June-August) and 1.11 (95% CI, 0.91-1.35; p = 0.29) for winter (December-February). These findings did not vary by sex, age at diagnosis or major subtypes. In contrast, there was no seasonal association between birthdate and risk of HL (p = 0.78). In this large cohort study, birth in spring or summer was associated with increased risk of NHL (but not HL) in childhood through young adulthood, possibly related to immunologic effects of delayed infectious exposures compared with fall or winter birth. These findings suggest that immunologic responses in early infancy may play an important role in the development of NHL. © 2014 UICC.

We hypothesized that living kidney donors born with lower birth weight may be at increased risk of hypertension, albuminuria or reduced GFR beyond what is typical following uninephrectomy. 257 living kidney donors who donated at the University of Minnesota between 1967 and 2005 underwent iohexol GFR and urinary albumin excretion measurements. Predictors of iohexol GFR <60 ml/min/1.73m2, albuminuria and hypertension were examined using logistic regression. Predictors examined include age at GFR measurement, time since donation, BMI, gender, serum creatinine level (at donation and GFR measurement), systolic and diastolic blood pressure, race, and birth weight. The latter was obtained through self-report and verified through birth certificates and family members. Older age, higher BMI, and time from donation were associated with reduced GFR. Older age and higher BMI were also associated with hypertension. Birth weight was not associated with GFR <60 ml/min/1.73m2: OR=0.70, 95% CI (0.28, 1.74, p=0.45) or hypertension: OR=0.92, 95% CI (0.46, 1.84), p=0.82 but was associated with albuminuria: OR=0.37, 95% CI (0.15, 0.92), p=0.03. This data further strengthens the link between low birth weight and potential adverse renal outcomes. PMID:24547690

    Background: The purpose of this study was to determine the prevalence and related factors of low birth weight (LBW) in the Southeast of Iran. Methods: This cross-sectional study was carried out in Kerman province. Data were collected from Iranian Maternal and Neonatal Network at public and private hospitals. All live births from March 2014 to March 2015 considered as the source population. The risk factors including maternal age, gravida, parity, abortion, pregnancy risk factors, maternal nationality, maternal education, maternity insurance, place of living, consanguinity, neonate sex, preterm labor, place of birth, delivery manager, and delivery type were compared between LBW and normal birth weight groups. Results: The prevalence of LBW was 9.4% in the present study. Preterm labor (odds ratio [OR]: 22.06; P 35 years (OR: 1.21; P = 0.001), delivery by cesarean section (OR: 1.17; P = 0.002), pregnancy risk factors (OR: 1.67; P 35 years old, and maternal medical risk factors are some critical interventions to reduce its burden. Increasing the access to high-quality health-care services in rural and deprived areas is another effective strategy for the prevention of LBW.

    Science.gov (United States)

    Hidalgo-Lopezosa, Pedro; Hidalgo-Maestre, María

    To assess the risk of uterine rupture (UR) in attempted vaginal birth after cesarean and to identify risk factors. Systematic review by consulting the following databases: PubMed (MEDLINE), Cochrane Library Plus, Embase, Nursing@Ovid, Cuidatge and Dialnet. The search was conducted between January and March 2015. MeSH descriptors used were: vaginal birth after cesarean; uterine rupture; labor induced and labor obstetric or trial of labor. There were no restrictions on date or language. The selection of articles was performed by 2 independent reviewers, standardized and unblinded. A critical review of the summary was conducted, and if was necessary, the full text was consulted. Prospective and retrospective documents were included. A total of 39 documents were included for their relevance and interest. Few clinical trials were found. The UR incidence on the results of the studies analyzed ranged from 0.15-0.98% in spontaneous labor; 0.3-1.5% in stimulation and induction with oxytocin, and 0.68-2.3% in prostaglandin inductions. The success of vaginal birth after cesarean is important and improves when conditions are optimal. However it is not without risks, the main one being UR. Induction of labor with oxytocin and/or prostaglandins appears as the main risk factor, while the spontaneous onset of labor and a prior vaginal birth are protective factors.

  10. Costing Alternative Birth Settings for Women at Low Risk of Complications: A Systematic Review.

    Directory of Open Access Journals (Sweden)

    Vanessa Scarf

    Full Text Available There is demand from women for alternatives to giving birth in a standard hospital setting however access to these services is limited. This systematic review examines the literature relating to the economic evaluations of birth setting for women at low risk of complications.Searches of the literature to identify economic evaluations of different birth settings of the following electronic databases: MEDLINE, CINAHL, EconLit, Business Source Complete and Maternity and Infant care. Relevant English language publications were chosen using keywords and MeSH terms between 1995 and 2015. Inclusion criteria included studies focussing on the comparison of birth setting. Data were extracted with respect to study design, perspective, PICO principles, and resource use and cost data.Eleven studies were included from Australia, Canada, the Netherlands, Norway, the USA, and the UK. Four studies compared costs between homebirth and the hospital setting and the remaining seven focussed on the cost of birth centre care and the hospital setting. Six studies used a cost-effectiveness analysis and the remaining five studies used cost analysis and cost comparison methods. Eight of the 11 studies found a cost saving in the alternative settings. Two found no difference in the cost of the alternative settings and one found an increase in birth centre care.There are few studies that compare the cost of birth setting. The variation in the results may be attributable to the cost data collection processes, difference in health systems and differences in which costs were included. A better understanding of the cost of birth setting is needed to inform policy makers and service providers.

    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.

    Objective The objective of this study was to investigate the association between contrast enema (CE) and clinical sepsis (CS) in premature babies (PB) and the role of antibiotics (ABs) in its prevention. Study Design A retrospective electronic chart review of preterm babies, who underwent CE during their stay in the neonatal intensive care unit. Group I includes CEs of babies exposed to AB during or within 48 hours of the procedure. Group II represents CEs of babies, not exposed to AB. Variables for both groups were collected and analyzed. Results There were 161 CEs performed in 133 babies. The overall incidence of CS after CE in preterm babies was 21/160 cases (13%). The incidence was significantly lower in Group I (1/79, 1.2%), compared with Group II (20/81, 24.7%) (p babies from Group II had positive blood culture and all 20 required AB after the CE. There were no statistical differences in the variables between the two groups. Conclusion There is a possible association between CE and CS in preterm babies. ABs given during or before the procedure prevent this complication.

    Developmental profiles and milestone attainment have been examined for children suffering from various developmental disabilities. However, research comparing the same across numerous developmental disabilities is scant. Therefore, the purpose of the current study was to examine the developmental profiles of toddlers (i.e. aged 17-34 months) who were premature, diagnosed with Down Syndrome, or diagnosed with Global Developmental Delay. A total of 28 toddlers met inclusion criteria for the study. Those diagnosed with Global Developmental Delay or Down Syndrome scored significantly lower on the Battelle Developmental Inventory, Second Edition (BDI-2), compared to those who were born premature. More specifically, differences emerged on the BDI-2 domains of personal-social and motor. Implications of these findings and directions for future research are discussed.

    A large proportion of the rise in prematurity worldwide is owing to late preterm births, which may be due to the expansion of obstetric interventions, especially pre-labour caesarean section. Late preterm births pose similar risks to overall prematurity, making this trend a concern. In this study, we describe factors associated with provider-initiated late preterm birth and verify differences in provider-initiated late preterm birth rates between public and private health services according to obstetric risk. This is a sub-analysis of a national population-based survey of postpartum women entitled "Birth in Brazil", performed between 2011 and 2012. We included 23,472 singleton live births. We performed non-conditional multiple logistic regressions assessing associated factors and analysing differences between public and private health services. Provider-initiated births accounted for 38% of late preterm births; 32% in public health services and 61% in private health services. They were associated with previous preterm birth(s) and maternal pathologies for women receiving both public and private services and with maternal age ≥35 years for women receiving public services. Women receiving private health services had higher rates of provider-initiated late preterm birth (rate of 4.8%) when compared to the ones receiving public services (rate of 2.4%), regardless of obstetric risk-adjusted OR of 2.3 (CI 1.5-3.6) for women of low obstetric risk and adjusted OR of 1.6 (CI 1.1-2.3) for women of high obstetric risk. The high rates of provider-initiated late preterm birth suggests a considerable potential for reduction, as such prematurity can be avoided, especially in women of low obstetric risk. To promote healthy births, we advise introducing policies with incentives for the adoption of new models of birth care.

    Primary prevention should be targeted at individuals with high global cardiovascular risk, but research is lacking on how best to identify such individuals in the general population. Family history is a good proxy measure of global risk and may provide an efficient mechanism for identifying high risk individuals. The aim was to test the feasibility of using patients with premature cardiovascular disease to recruit family members as a means of identifying and screening high-risk individuals. We recruited family members of 50 patients attending a cardiology clinic for premature coronary heart disease (CHD). We compared their cardiovascular risk with a general population control group, and determined their perception of their risk and current level of screening. 103 (36%) family members attended screening (27 siblings, 48 adult offspring and 28 partners). Five (5%) had prevalent CHD. A significantly higher percentage had an ASSIGN risk score >20% compared with the general population (13% versus 2%, p family members were aware they were at increased risk and only 50% had had their blood pressure and serum cholesterol level checked in the previous three years. Patients attending hospital for premature CHD provide a mechanism to contact family members and this can identify individuals with a high global risk who are not currently screened.

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

    2014-02-01

    The aim of the article was to investigate the relationship between pregnancy complications, infertility and assisted reproductive technologies (ART). The study was conducted on 1331 couples with complicated reproductive history. It is found that miscarriage and other complications of pregnancy depend rather on the etiopathogenesis of infertility than on the technique of ART. The highest frequency of complications of pregnancy was diagnosed in women with endocrine disorders. In case of congenital malformations in the fetus the frequency of birth defects was 3.6% after in vitro fertilization (IVF) and 1.8% in case of spontaneous pregnancy. It was found an increased risk of birth defects in singleton boys conceived by IVF.

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

    Full Text Available BACKGROUND: Coronary artery disease is very common in Pakistani population. Some of the studies carried out on Western populations have shown a relationship between body iron status as determined by the ratio of concentrations of serum soluble transferrin receptor (sTfR to ferritin and the risk of acute myocardial infarction (AMI. In order to investigate whether increased body iron status has any relationship with the risk of premature AMI in Pakistani population, a case-control study was carried out. METHODOLOGY/PRINCIPAL FINDINGS: In this case-control study, 203 consecutive AMI patients [146 males and 57 females; age range 18-45 years] admitted to the National Institute for Cardiovascular Diseases, Karachi, were enrolled with informed consent. In addition, 205 healthy controls whose gender and age (within 3 years matched the patients, and who had a similar socio-economic background were recruited. Fasting venous blood was obtained and assessed for plasma/serum folate, vitamin B12, homocysteine, total cholesterol, triglycerides, LDL-cholesterol, HDL-cholesterol, sTfR and ferritin and blood lead. It was found that serum concentration of ferritin and blood lead levels were significantly higher in AMI patients compared to their age and gender-matched healthy controls (p value <0.05, while the concentrations of vitamin B12 and HDL-cholesterol were significantly lower in AMI patients compared to controls (p value <0.01. The ratio of sTfR to ferritin was significantly lower in AMI patients compared to controls [mean ± SD/median (IQR values 84.7 ± 295/28.9 (38.4 vs 255 ± 836/49.4 (83.8, respectively; p value <0.001]. Compared with the highest quartile of sTfR/ferritin (low body iron status, the OR for the risk of AMI was 3.29(95% CI, 1.54-7.03 for the lowest quartile (quartile 1 when the model was adjusted for vitamin B12 and HDL-cholesterol (p value for trend <0.01. CONCLUSIONS/SIGNIFICANCE: This study shows a positive association between total

    Objective To analyse bronchopulmonary dysplasia (BPD) incidence and high risk factor in the small gestational age premature infants. Methods Retrospective analyse the materials of inpatient infants whose gestational age (GA) were =?2 weeks and survived over 28 days in our neonatal intensive care unite ( NICU). The 28 cases as BPD group met the new diagnostic criteria of BPD. The 56 cases as the control group were randomly selected from all the premature infant with no BPD. Results Total of 197 cases of premature infant were included in this study. The incidence of BPD is about 14.2%. There were statistical significance in each GA period group (x2 =32.269,/* =0.000). The incidence increased when the GA decreased; There were statistical significance in each birth weight group (x2 =30. 244, P =0. 000), the incidence increased when birth weight decreased. From the comparison of the 23 risk factors for BPD, we find thai 12 factors have statistical significance (P < 0. 05), those are GA, body weight, oxygen time, maximum oxygen treatment concentration, hospital days, tracheal intubation mechanical ventilation, replacement therapy with pulmonary surfactant, anemia, application of Meropenem, the ratio of tenth day body weight to birth weight, the first blood gas analysis scores after birth and oxygen index < 300. On the basis of Logistic regression analysis of GA, birth weight, the highest inhaled oxygen volume concentration, tracheal intubation mechanical ventilation, anemia, the ratio of tenth day body weight to birth weight, we find that body weight, the highest inhaled oxygen volume concentration, the ratio of tenth body weight to birth weight are high risk factors for BPD. By compared the 18 factors between mild BPD and moderate or severe BPD, we find that asphyxia, application of diuretic, oxygen time and first blood gas analysis scores after birth have statistical significance ( P < 0.05 ) . Conclusions The birth weight, the highest inhaled oxygen volume

    Child maltreatment and other adverse childhood experiences adversely influence population health and socioeconomic outcomes. Knowledge of the risk factors for child maltreatment can be used to identify children at risk and may represent opportunities for prevention. We examined a range of possible child, parent and family risk factors for child maltreatment in a prospective 27-year population-based birth cohort of 2443 Australians. Physical abuse, sexual abuse, emotional abuse, neglect and witnessing of domestic violence were recorded retrospectively in early adulthood. Potential risk factors were collected prospectively during childhood or reported retrospectively. Associations were estimated using bivariate and multivariate logistic regressions and combined into cumulative risk scores. Higher levels of economic disadvantage, poor parental mental health and substance use, and social instability were strongly associated with increased risk of child maltreatment. Indicators of child health displayed mixed associations and infant temperament was uncorrelated to maltreatment. Some differences were observed across types of maltreatment but risk profiles were generally similar. In multivariate analyses, nine independent risk factors were identified, including some that are potentially modifiable: economic disadvantage and parental substance use problems. Risk of maltreatment increased exponentially with the number of risk factors experienced, with prevalence of maltreatment in the highest risk groups exceeding 80%. A cumulative risk score based on the independent risk factors allowed identification of individuals at very high risk of maltreatment, while a score that incorporated all significant risk and protective factors provided better identification of low-risk individuals.

    Background A large proportion of the rise in prematurity worldwide is owing to late preterm births, which may be due to the expansion of obstetric interventions, especially pre-labour caesarean section. Late preterm births pose similar risks to overall prematurity, making this trend a concern. In this study, we describe factors associated with provider-initiated late preterm birth and verify differences in provider-initiated late preterm birth rates between public and private health services according to obstetric risk. Methods This is a sub-analysis of a national population-based survey of postpartum women entitled “Birth in Brazil”, performed between 2011 and 2012. We included 23,472 singleton live births. We performed non-conditional multiple logistic regressions assessing associated factors and analysing differences between public and private health services. Results Provider-initiated births accounted for 38% of late preterm births; 32% in public health services and 61% in private health services. They were associated with previous preterm birth(s) and maternal pathologies for women receiving both public and private services and with maternal age ≥35 years for women receiving public services. Women receiving private health services had higher rates of provider-initiated late preterm birth (rate of 4.8%) when compared to the ones receiving public services (rate of 2.4%), regardless of obstetric risk–adjusted OR of 2.3 (CI 1.5–3.6) for women of low obstetric risk and adjusted OR of 1.6 (CI 1.1–2.3) for women of high obstetric risk. Conclusion The high rates of provider-initiated late preterm birth suggests a considerable potential for reduction, as such prematurity can be avoided, especially in women of low obstetric risk. To promote healthy births, we advise introducing policies with incentives for the adoption of new models of birth care. PMID:27196102

    There is evidence that pregnancy-specific stress is associated with preterm birth. The purpose of this study is to examine the association between change in pregnancy-specific stress over the course of pregnancy and birth outcomes (i.e., preterm birth and gestational age) in an understudied but vulnerable group using a theoretically derived model. Multivariate linear and logistic regression techniques were used to examine the association between pregnancy-specific stress (measured in second and third trimester) and length of gestation (i.e., preterm birth and gestational age) among a sample of 920 Black and/or Latina adolescent and young women. Second trimester pregnancy-specific stress was not associated with preterm birth or gestational age. Third trimester pregnancy-specific stress was associated with preterm birth but not with gestational age. Change in pregnancy-specific stress between second and third trimester was significantly associated with increased likelihood of preterm delivery and shortened gestational age, even after controlling for important biological, behavioral, psychological, interpersonal, and sociocultural risk factors. Findings emphasize the importance of measuring pregnancy-specific stress across pregnancy, as the longitudinal change from second to third trimester was significantly associated with length of gestation measured both as a dichotomous variable (preterm birth) and a continuous variable (gestational age). Furthermore, this is the first study to observe the association of pregnancy-specific stress with length of gestation in this understudied population-unique in age, race, and ethnicity.

    Birth in a group of predominantly southern US states is robustly linked to increased stroke risk. Given the role of cerebrovascular disease in dementia risk, geographic patterning may also occur for dementia incidence. To determine whether birth in 9 high stroke mortality states (HSMSs) is associated with dementia in a diverse cohort of individuals living in Northern California. An observational cohort study included 7423 members of Kaiser Permanente Northern California (KPNC), an integrated health care delivery system, with health survey and clinical examination data available. Data were collected between 1964 and 1973 when the individuals were middle-aged and 1996 and 2015 when participants were in later life. Self-reported state of birth in an HSMS (top quintile of states for stroke mortality). Dementia diagnoses obtained from electronic health records from January 1, 1996, to October 15, 2015. Place of birth, race, educational level, and midlife vascular risk factors data were collected between 1964 and 1973. Of the 7423 persons included in the analysis, 4049 (54.5%) were women; 1354 (18.2%) were black. The mean (SD) age of study participants at their first visit between 1963 and 1974 was 42.94 (1.73) years and mean (SD) age at the beginning of follow-up for dementia in 1996 was 71.14 (2.72) years. Dementia was diagnosed in 2254 (30.4%) of the participants and was more common among those born in an HSMS than those born outside of one (455 [39.0%] vs 1799 [28.8%]). Birth in an HSMS was 9.6 times more common for black participants (795 [58.7%]) than nonblack participants (371 [6.1%]). Overall, birth in an HSMS was associated with a 28% higher risk of dementia (adjusted hazard ratio [aHR], 1.28; 95% CI, 1.13-1.46) adjusted for age, sex, and race. Compared with nonblack persons born outside of an HSMS, black individuals born in an HSMS had the highest dementia risk (aHR, 1.67; 95% CI, 1.48-1.88), followed by black individuals not born in an HSMS (aHR, 1.48; 95% CI

    Work-related risk factors, such as long work hours, and physically demanding work have been suggested to adversely influence pregnancy outcome. The authors aimed to examine associations between various aspects of physically demanding work with fetal growth in different trimesters during pregnancy and the risks of adverse birth outcomes. Associations between physically demanding work and fetal growth were studied in 4680 pregnant women participating in a population-based prospective cohort study from early pregnancy onwards in The Netherlands (2002-2006). Mothers who filled out a questionnaire during mid-pregnancy (response 77% of enrolment) were included if they conducted paid employment and had a spontaneously conceived singleton live born pregnancy. Questions on physical workload were obtained from the Dutch Musculoskeletal Questionnaire and concerned questions on lifting, long periods of standing or walking, night shifts and working hours. Fetal growth characteristics were repeatedly measured by ultrasound and were used in combination with measurements at birth. There were no consistent significant associations between physically demanding work nor working hours in relation to small for gestational age, low birth weight or preterm delivery. Women exposed to long periods of standing had lower growth rates for fetal head circumference (HC), resulting in a reduction of approximately 1 cm (3%) of the average HC at birth. Compared with women working 40 h/week had lower growth rates for both fetal weight and HC, resulting in a difference of approximately 1 cm in HC at birth and a difference of 148-198 g in birth weight. Long periods of standing and long working hours per week during pregnancy seem to negatively influence intrauterine growth.

    Full Text Available We examined the association of occupational exposure to handling cytotoxic drugs at work with risk of birth defects among a cohort of female veterinarians. This study is a follow up survey of 321 female participants (633 pregnancies who participated in the Health Risks of Australian Veterinarian project. Data on pregnancies and exposure during each pregnancy was obtained by self-administered mailed questionnaire. Female veterinarians handling cytotoxic drugs during their pregnancy had a two-fold increased risk of birth defects in their offspring (RR = 2.08, 95% CI (1.05–4.15. Results were consistent in subgroup analysis of those who graduated during the period of 1961 to 1980 (RR = 5.04, 95% CI (1.81, 14.03 and in those working specifically in small and large animal practice. There was no increased risk in the subgroup that graduated after 1980. Women with unplanned pregnancies were more likely to handle cytotoxic drugs on a daily basis (RR = 1.86, 95% CI, 1.00–3.48 and had a higher increased risk of birth defects than those who planned their pregnancies in recent graduates and in those who worked specifically in small animal practice (RR = 2.53, 95% CI, 1.18–5.42. This study suggests that the adverse effects of handling cytotoxic drugs in pregnant women may include an increased risk of birth defects. Pregnancy intention status is an important health behavior and should be considered in prenatal programs.
