The sequelae of preterm births may differ, depending on whether birth follows an acute event or a chronic condition. In a population-based cohort study of 2,711,645 Canadian hospital deliveries from 2003 to 2012, 3,059 women experienced unintentional injury during pregnancy. We assessed the impact of the acute event on pregnancy outcome and on neonatal complications, such as nontraumatic intracranial hemorrhage, respiratory distress syndrome, intubation, and death. We adjusted for maternal age, parity, pregnancy conditions, and (for neonates) gestational age in logistic regression analyses. Injury was significantly associated with fetal mortality and early preterm delivery. For preterm infants born to injured women during the hospitalization for injury versus those born to noninjured women, the adjusted odds ratios were 2.25 (95% confidence interval (CI): 1.23, 4.17) for neonatal death, 2.44 (95% CI: 1.76, 3.37) for respiratory distress, 2.20 (95% CI: 1.26, 3.84) for nontraumatic intracranial hemorrhage, and 2.17 (95% CI: 1.60, 2.96) for intubation, despite more favorable fetal growth in those born to noninjured women (adjusted birth-weight-for-gestational-age z score: 0.154 vs. 0.024, P = 0.041; small-for-gestational-age rate: 4.5% vs. 9.5%, P = 0.001). Our findings suggest that adaptation to the suboptimal intrauterine environment underlying chronic causes of preterm birth may protect preterm infants from adverse sequelae. © The Author 2015.

at home and to compare the prevalence of perineal injuries, SPT and episiotomy in different birth positions in four Nordic countries. METHODS: A population-based prospective cohort study of planned home births in four Nordic countries. To assess medical outcomes a questionnaire completed after birth...... by the attending midwife was used. Descriptive statistics, bivariate analysis and logistic regression were used to analyze the data. RESULTS: Two thousand nine hundred ninety-two women with planned home births, who birthed spontaneously at home or after transfer to hospital, between 2008 and 2013 were included.......26-1.79). Flexible sacrum positions were associated with fewer episiotomies (OR 0.20; CI 95 % 0.10-0.54). CONCLUSION: A low prevalence of SPT and episiotomy was found among women opting for a home birth in four Nordic countries. Women used a variety of birth positions and a majority gave birth in flexible sacrum...

The rate of multiple births has increased over the last two decades. In 1982, an increased frequency of injuries among this patient population was noted, but few studies have evaluated the increased incidence of maltreatment in twins. The study aim was to evaluate the features of all multiple-birth children with substantiated physical abuse and/or neglect over a four-year period at a major children's hospital. A Retrospective chart review was conducted of multiple-gestation children in which at least one child in the multiple set experienced child maltreatment from January 2006 to December 2009. Data regarding the child, injuries, family, and perpetrators were abstracted. We evaluated whether family and child characteristics were associated with maltreatment, and whether types of injuries were similar within multiple sets. For comparison, data from the same time period for single-birth maltreated children also were abstracted, including child age, gestational age at birth, and injury type. There were 19 sets of multiple births in which at least one child had abusive injuries and/or neglect. In 10 of 19 sets (53%), all multiples were found to have a form of maltreatment, and all children in these multiple sets shared at least one injury type. Parents lived together in 63% of cases. Fathers and mothers were the alleged perpetrator in 42% of the cases. Multiple-gestation-birth maltreated children were significantly more likely than single-birth maltreated children to have abdominal trauma (13% vs. 1%, respectively; pchildren often, but not always, were abused. In sets with two maltreated children, children usually shared the same modes of maltreatment. Multiples are significantly more likely than singletons to be younger and experience fractures and abdominal trauma. The findings support the current standard practice of evaluating all children in a multiple set when one is found to be abused or neglected. Copyright © 2013 Elsevier Ltd. All rights reserved.

To explore the relationship between perinatal brain injury, visual motor function (VMF) and poor school outcome. Little is known about the status and underlying mechanism of poor school outcome as experienced by low birth weight survivors. This is a secondary data analysis. The parental study recruited 1104 low birth weight (LBW) infants weighing ≤ 2000 g from three medical centres of Central New Jersey between 1984 and 1987. Seven hundred and seventy-seven infants survived the neonatal period, and their developmental outcomes had been following up regularly until now. The development data of the survivors were used to achieve the research aims. Initial school outcome assessment was carried out in 9-year-old, using the Woodcock-Johnson Academic Achievement Scale. The severity and range of perinatal brain injury was determined by repeated neonatal cranial ultrasound results obtained at 4 hours, 24 hours and 7 days of life. Seventeen and a half per cent of the sample experienced poor school performance at age 9 as defined by lower than one standard deviation (SD) of average performance score. Children with the most severe injury, PL/VE, had the lowest mathematics (F = 14·54, p = 0·000) and reading (anova results: F = 11·56, p = 0·000) performances. Visual motor function had a significant effect on children's overall school performance (Hotelling's trace value was 0·028, F = 3·414, p = 0·018), as well as subtest scores for reading (p = 0·006) and mathematics (p = 0·036). However, visual motor function was not a mediator in the association of perinatal brain injury and school outcome. Perinatal brain injury had a significant long-term effect on school outcome. Low birth weight infants with history of perinatal brain injury need be closely monitored to substantially reduce the rates of poor school outcome and other neurodevelopmental disabilities. © 2012 Blackwell Publishing Ltd.

Brachial plexus birth injuries with multiple nerve root avulsions present a particularly difficult reconstructive challenge because of the limited availability of donor nerves. The contralateral C7 has been described for brachial plexus reconstruction in adults but has not been well-studied in the pediatric population. We present our technique and results for retropharyngeal contralateral C7 nerve transfer to the lower trunk for brachial plexus birth injury. We performed a retrospective review. Any child aged less than 2 years was included. Charts were analyzed for patient demographic data, operative variables, functional outcomes, complications, and length of follow-up. We had a total of 5 patients. Average nerve graft length was 3 cm. All patients had return of hand sensation to the ulnar nerve distribution as evidenced by a pinch test, unprompted use of the recipient limb without mirror movement, and an Active Movement Scale (AMS) of at least 2/7 for finger and thumb flexion; one patient had an AMS of 7/7 for finger and thumb flexion. Only one patient had return of ulnar intrinsic hand function with an AMS of 3/7. Two patients had temporary triceps weakness in the donor limb and one had clinically insignificant temporary phrenic nerve paresis. No complications were related to the retropharyngeal nerve dissection in any patient. Average follow-up was 3.3 years. The retropharyngeal contralateral C7 nerve transfer is a safe way to supply extra axons to the severely injured arm in brachial plexus birth injuries with no permanent donor limb deficits. Early functional recovery in these patients, with regard to hand function and sensation, is promising. Therapeutic V. Copyright © 2018 American Society for Surgery of the Hand.

Clinicians hand position and advised pushing techniques may impact on rates of perineal injury. To assess the association of four techniques used in management of second stage with risk of moderate and severe perineal injury. Retrospective cross-sectional study. A metropolitan maternity hospital and a private maternity hospital in Brisbane, Australia. Term women with singleton, cephalic presentation experiencing a non-operative vaginal birth from January 2011 to December 2016. The research sites perinatal database recorded data on clinicians approach to instructing women during second stage and hand position at birth. Women were identified from matching the inclusion criteria (n = 26,393) then grouped based on combinations of hands-on, hand- poised, directed and undirected pushing. The associations with perineal injury were estimated using odds ratios obtained by multivariate analysis. Primary outcomes were the risk of moderate and severe perineal injury. The significance was set at 0.001. In Nulliparous women there was no difference in the risk of moderate or severe perineal injury between the different techniques. In multiparous women the use of a hands-on/directed approach was associated with a significant increase in the risk of moderate (AOR 1.18, 95% CI 1.10-1.27, p < 0.001) and severe perineal injury (AOR 1.50, 95% CI 1.20-1.88, p < 0.001) compared to hands-poised/undirected. A hands poised/undirected approach could be utilised in strategies for the prevention of moderate and severe perineal injury. Copyright © 2018 Elsevier Ltd. All rights reserved.

Little is known about the incidence and prevalence of traumatic brain injury (TBI), particularly for infants, children and young adults. The purpose of this study was to provide an accurate estimate of the incidence and prevalence of TBIs for individuals between 0-25 years of age. A birth cohort of 1265 individuals was used, for which information regarding TBI events, both hospitalized and non-hospitalized, had been recorded. The average incidence for this age group ranged from 1.10-2.36 per 100 per year, with an overall prevalence of approximately 30%. The most common source of injury was falls for individuals 0-14 years of age and contact sports and motor vehicle accidents for 15-25 year olds. Approximately one third of the individuals who experienced a TBI went on to have one or more additional injuries. The incidence rates reported here are much higher than those previously found. It is clear that TBIs constitute a major health issue and therefore it is important to have accurate information to enable planning for primary healthcare services and to inform prevention programmes.

Psychotropic drug use as indicator of mental health in adolescents affected by a plexus injury at birth: A large population-based study in Sweden.

Directory of Open Access Journals (Sweden)

Full Text Available Chronic handicap in early life may have a long-term impact on children's psychosocial well-being. Here, we investigated whether Brachialis Plexus Birth Injury (BPBI-an unpredictable injury at birth-is associated with worse mental health later on, as indicated by prescription and use of psychotropic drugs in adolescence. We explored further whether this association is different depending on socioeconomic characteristics of the child's family, as well as sex. Of the 641 151 children born to native parents in Sweden 1987-1993 (alive and still living in Sweden at the end of 2008, identified in the Swedish Medical Birth Registry, 1587 had suffered a BPBI. Logistic regression analysis was performed to assess the impact of socioeconomic characteristics and associations with later psychosocial health. Results show that beyond the known increased risks for females as compared to males, BPBI, but also lower family income, further increased the risk of burdened mental health requiring psychotropic drug use in adolescence. The effects were additive. Thus, compared to unaffected peers, teenagers who suffered a BPBI at birth are at higher risk of suffering poor mental health during adolescence, independently of surgical intervention and its outcome. Girls growing up in families with lower socioeconomic status have this risk added to their already increased risk of poor mental health during adolescence.

To provide reliability information for a brief observational measure of physical disorder and determine its relation with neighbourhood level crime and health variables after controlling for census based measures of concentrated poverty and minority concentration. Psychometric analysis of block observation data comprising a brief measure of neighbourhood physical disorder, and cross sectional analysis of neighbourhood physical disorder, neighbourhood crime and birth statistics, and neighbourhood level poverty and minority concentration. Pittsburgh, Pennsylvania, US (2000 population=334 563). Pittsburgh neighbourhoods (n=82) and their residents (as reflected in neighbourhood level statistics). The physical disorder index showed adequate reliability and validity and was associated significantly with rates of crime, firearm injuries and homicides, and teen births, while controlling for concentrated poverty and minority population. This brief measure of neighbourhood physical disorder may help increase our understanding of how community level factors reflect health and crime outcomes.

Standard brachial plexus repair techniques often involve autologous nerve graft placement and neurotization. However, when performed to treat severe injuries, this procedure can sometimes yield poor results. Moreover, harvesting the autologous graft is time-consuming and exposes the patient to additional surgical risks. To improve surgical outcomes and reduce surgical risks associated with autologous nerve graft retrieval and placement, the authors use collagen matrix tubes (Neurogen) instead of autologous nerve graft material. Between 1991 and 2005, the authors surgically treated 65 infants who had suffered brachial plexus injury at birth. During this time, seven patients were treated using collagen matrix tubes (Neurogen). This study is a retrospective analysis of the initial five patients who were treated using the tubes. Two patients underwent tube placement recently and were excluded from the analysis because of the inadequate follow-up period. Four of the five patients experienced a good recovery (motor scale composite [MSC] > 0.6), and three exhibited an excellent recovery (MSC > 0.75) at 2 years postoperatively. The MSC improved by an average of 69 and 78% at 1 and 2 years, respectively. The movement scores improved to greater than or equal to 50% range of motion in most patients, and the contractures were usually mild or moderate. Follow-up physical and occupational therapy evaluations confirm these patients' functional status. When last seen, four of five of these children could feed and dress themselves. Technically, the use of the collagen matrix tubes was straightforward and efficient, and there were no complications. The outcomes in this small series are encouraging.

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

Internal rotation contracture is the most common shoulder deformity in patients with brachial plexus birth injury. The purpose of this investigation is to describe the indications, technique, and results of the subscapularis slide procedure. The technique involves the release of the subscapularis muscle origin off the scapula, with preservation of anterior shoulder structures. A standard postoperative protocol is used in all patients and includes a modified shoulder spica with the shoulder held in 60 degrees of external rotation and 30 degrees of abduction, aggressive occupational and physical therapy, and subsequent shoulder manipulation under anesthesia with botulinum toxin injections as needed. Seventy-one patients at 2 institutions treated with subscapularis slide between 1997 and 2010, with minimum follow-up of 39.2 months, were identified. Patients were divided into 5 groups based on the index procedure performed: subscapularis slide alone (group 1); subscapularis slide with a simultaneous microsurgical reconstruction (group 2); primary microsurgical brachial plexus reconstruction followed later by a subscapularis slide (group 3); primary microsurgical brachial plexus reconstruction followed later by a subscapularis slide combined with tendon transfers for shoulder external rotation (group 4); and subscapularis slide with simultaneous tendon transfers, with no prior brachial plexus surgery (group 5). Full passive external rotation equivalent to the contralateral side was achieved in the operating room in all cases. No cases resulted in anterior instability or internal rotation deficit. Internal rotation contracture of the shoulder after brachial plexus birth injury can be effectively managed with the technique of subscapularis slide.

Objective Neonatal seizures in the first 28 days of life often reflect underlying brain injury or abnormalities, and measure the quality of perinatal care in out-of-hospital births. Using the 2003 revision of birth certificates only, three studies reported more neonatal seizures recorded among home births ​or planned out-of-hospital births compared to hospital births. However, the validity of recording neonatal seizures or serious neurologic dysfunction across birth settings in birth certificates has not been evaluated. We aimed to validate seizure recording in birth certificates across birth settings using multiple datasets. Methods We examined checkbox items "seizures" and "seizure or serious neurologic dysfunction" in the 1989 and 2003 revisions of birth certificates in South Carolina from 1996 to 2013. Gold standards were ICD-9-CM codes 779.0, 345.X, and 780.3 in either hospital discharge abstracts or Medicaid encounters jointly. Results Sensitivity, positive predictive value, false positive rate, and the kappa statistic of neonatal seizures recording were 7%, 66%, 34%, and 0.12 for the 2003 revision of birth certificates in 547,177 hospital births from 2004 to 2013 and 5%, 33%, 67%, and 0.09 for the 1998 revision in 396,776 hospital births from 1996 to 2003, and 0, 0, 100%, -0.002 among 660 intended home births from 2004 to 2013 and 920 home births from 1996 to 2003, respectively. Conclusions for Practice Despite slight improvement across revisions, South Carolina birth certificates under-reported or falsely reported seizures among hospital births and especially home births. Birth certificates alone should not be used to measure neonatal seizures or serious neurologic dysfunction.

White matter injury (WMI) is the characteristic pattern of brain injury detected on magnetic resonance imaging in the premature newborn. Focal noncystic WMI is increasingly recognized in populations of term newborns. The aim of this study was to describe the occurrence of focal noncystic WMI in a cohort of 48 term newborns with encephalopathy studied with magnetic resonance imaging at 72 +/- 12 h of life, and to identify clinical risk factors for this pattern of injury. Eleven newborns (23%; 95% CI 11-35) were found to have WMI (four minimal, three moderate, and four severe). In 10 of the 11 newborns, the WMI was associated with restricted diffusion on apparent diffusion coefficient maps. An increasing severity of WMI was associated with lower gestational age at birth (p = 0.05), but not lower birth weight. Newborns with WMI had milder encephalopathy and fewer clinical seizures relative to other newborns in the cohort. Other brain injuries were seen in three of the 11 newborns: basal nuclei predominant pattern of injury in one and cortical strokes in two. These findings suggest that WMI in the term newborn is acquired near birth and that the state of brain maturation is an important determinant of this pattern of brain injury.

Biomarkers of brain injury in the premature infant

2013-01-01

Full Text Available The term encephalopathy of prematurity encompasses not only the acute brain injury (such as intraventricular hemorrhage but also complex disturbance on the infant’s subsequent brain development. In premature infants, the most frequent recognized source of brain injury is intraventricular hemorrhage (IVH and periventricular leukomalacia (PVL. Furthermore 20-25% infants with birth weigh less than 1,500 g will have IVH and that proportion increases to 45% if the birth weight is less than 500-750 g. In addition, nearly 60% of very low birth weight newborns will have hypoxic-ischemic injury. Therefore permanent lifetime neurodevelopmental disabilities are frequent in premature infants. Innovative approach to prevent or decrease brain injury in preterm infants requires discovery of biomarkers able to discriminate infants at risk for injury, monitor the progression of the injury and assess efficacy of neuroprotective clinical trials. In this article, we will review biomarkers studied in premature infants with IVH, Post-hemorrhagic ventricular dilation (PHVD and PVL including: S100b, Activin A, erythropoietin, chemokine CCL 18, GFAP and NFL will also be examined. Some of the most promising biomarkers for IVH are S100β and Activin. The concentrations of TGF-β1, MMP-9 and PAI-1 in cerebrospinal fluid could be used to discriminate patients that will require shunt after post-hemorrhagic ventricular dilation. Neonatal brain injury is frequent in premature infants admitted to the neonatal intensive care and we hope to contribute to the awareness and interest in clinical validation of established as well as novel neonatal brain injury biomarkers.

Background  The reported incidence of brachial plexus birth injury (BPBI) is 0.87 to 2.2 per 1,000 live births. The psychological functioning, including self-concept and emotional-behavioral functioning, of children with BPBI has only been examined to a limited extent. Objective  The purpose of this study was to describe the self-concept and emotional-behavioral functioning in children with BPBI from both the child's and parent's perspective. Methods  Thirty-one children with BPBI, mean age 11 years 1 month, completed the Draw A Person: Screening Procedure for Emotional Disturbance (DAP:SPED) and Piers Harris Children's Self-Concept Scale (PHCSCS). The parents answered questions from the Behavior Assessment System for Children, Parent Rating Scales (BASC-2 PRS). Results  The scores from the DAP:SPED drawings showed further evaluation was not strongly indicated in the majority of the children. The PHCSCS Total score demonstrated that the children had a strongly positive self-concept. The parental responses to the BASC-2 PRS indicated that few children were at risk or in the clinically significant range for the four composite scores and all of the component clinical or adaptive scales. Gender comparison revealed females exhibited greater anxiety than males. Conclusion  Both children and parents reported a positive psychological well-being for the majority of the children. Parents had greater concerns about their child's social-emotional functioning, particularly anxiety. An interdisciplinary approach (occupational therapy evaluation, clinical observation, and parental interview) is necessary to determine the need for mental health referral.

The aim of this population-based study was to measure the risk of adverse outcome for mother and child in planned home births in a Swedish population irrespective of where the birth actually occurred, at home or in hospital after transfer. A population-based study using data from the Swedish Medical Birth Register. Sweden 1992-2004. A total of 897 planned home births were compared with a randomly selected group of 11,341 planned hospital births. Prevalence of mortality and morbidity among mothers and children, emergency conditions, instrumental and operative delivery and perineal lacerations were compared. During this period in Sweden the neonatal mortality rate was 2.2 per thousand in the home birth group and 0.7 in the hospital group (RR 3.6, 95% CI 0.2-14.7). No cases of emergency complications were found in the home birth group. The risk of having a sphincter rupture was lower in the planned home birth group (RR 0.2, 95% CI 0.0-0.7). The risk of having a cesarean section (RR 0.4, 95% CI 0.2-0.7) or instrumental delivery (RR 0.3, 95% CI 0.2-0.5) was significantly lower in the planned home birth group. In Sweden, between 1992 and 2004, the intrapartum and neonatal mortality in planned home births was 2.2 per thousand. The proportion is higher compared to hospital births but no statistically significant difference was found. Women in the home birth group more often experienced a spontaneous birth without medical intervention and were less likely to sustain pelvic floor injuries.

Neonatal brain injury and neuroanatomy of memory processing following very preterm birth in adulthood: an fMRI study.

Directory of Open Access Journals (Sweden)

Anastasia K Kalpakidou

Full Text Available Altered functional neuroanatomy of high-order cognitive processing has been described in very preterm individuals (born before 33 weeks of gestation; VPT compared to controls in childhood and adolescence. However, VPT birth may be accompanied by different types of adverse neonatal events and associated brain injury, the severity of which may have differential effects on brain development and subsequent neurodevelopmental outcome. We conducted a functional magnetic resonance imaging (fMRI study to investigate how differing degrees of neonatal brain injury, detected by neonatal ultrasounds, affect the functional neuroanatomy of memory processing in VPT young adults. We used a verbal paired associates learning task, consisting of four encoding, four cued-recall and four baseline condition blocks. To further investigate whether differences in neural activation between the groups were modulated by structural brain changes, structural MRI data were also collected. We studied 12 VPT young adults with a history of periventricular haemorrhage with associated ventricular dilatation, 17 VPT individuals with a history of uncomplicated periventricular haemorrhage, 12 individuals with normal ultrasonographic findings, and 17 controls. Results of a linear trend analysis demonstrated that during completion of the paired associates learning task right frontal and right parietal brain activation decreased as the severity of neonatal brain injury increased. There were no statistically significant between-group differences in on-line task performance and participants' intelligence quotient (IQ at assessment. This pattern of differential activation across the groups was observed particularly in the right middle frontal gyrus during encoding and in the right posterior cingulate gyrus during recall. Structural MRI data analysis revealed that grey matter volume in the right superior temporal gyrus, right cerebellum, left middle temporal gyrus, right globus pallidus and

To examine how the recovery following Hurricane Katrina affected pregnancy outcomes. 308 New Orleans area pregnant women were interviewed 5-7 years after Hurricane Katrina about their exposure to the disaster (danger, damage, and injury); current disruption; and perceptions of recovery. Birthweight, gestational age, birth length, and head circumference were examined in linear models, and low birthweight (<2500 g) and preterm birth (<37 weeks) in logistic models, with adjustment for confounders. Associations were found between experiencing damage during Katrina and birthweight (adjusted beta for high exposure = -158 g) and between injury and gestational age (adjusted beta = -0.5 days). Of the indicators of recovery experience, most consistently associated with worsened birth outcomes was worry that another hurricane would hit the region (adjusted beta for birthweight: -112 g, p = 0.08; gestational age: -3.2 days, p = 0.02; birth length: -0.65 cm, p = 0.06). Natural disaster may have long-term effects on pregnancy outcomes. Alternately, women who are most vulnerable to disaster may be also vulnerable to poor pregnancy outcome.

To describe the leading mechanisms of hospitalised unintentional injury in Australian Aboriginal children and identify the injury mechanisms with the largest inequalities between Aboriginal and non-Aboriginal children. We used linked hospital and mortality data to construct a whole of population birth cohort including 1,124,717 children (1,088,645 non-Aboriginal and 35,749 Aboriginal) born in the state of New South Wales (NSW), Australia, between 1 July 2000 and 31 December 2012. Injury hospitalisation rates were calculated per person years at risk for injury mechanisms coded according to the ICD10-AM classification. The leading injury mechanisms in both groups of children were falls from playground equipment. For 66 of the 69 injury mechanisms studied, Aboriginal children had a higher rate of hospitalisation compared with non-Aboriginal children. The largest relative inequalities were observed for injuries due to exposure to fire and flame, and the largest absolute inequalities for injuries due to falls from playground equipment. Aboriginal children in NSW experience a significant higher burden of unintentional injury compared with their non-Aboriginal counterparts. Implications for Public Health: We suggest the implementation of targeted injury prevention measures aimed at injury mechanism and age groups identified in this study. © 2016 The Authors.

The natural history and management of brachial plexus birth palsy

OpenAIRE

Buterbaugh, Kristin L.; Shah, Apurva S.

2016-01-01

Brachial plexus birth palsy (BPBP) is an upper extremity paralysis that occurs due to traction injury of the brachial plexus during childbirth. Approximately 20 % of children with brachial plexus birth palsy will have residual neurologic deficits. These permanent and significant impacts on upper limb function continue to spur interest in optimizing the management of a problem with a highly variable natural history. BPBP is generally diagnosed on clinical examination and does not typically req...

The first part of the study involved data collection for the detection of geographic variations and chronologic fluctuations in the rates of shoulder dystocia. The second part of the research evaluated head-to-body delivery times in cases of arrest of the shoulders at birth that had resulted in fetal damage during the last four decades in the USA. The study of geographic and chronologic changes in the rates of shoulder dystocia rested on reported statistics coming from the USA and 11 other countries. These data were obtained by computer search. Evaluation of head-to-body delivery times rested on 104 well-documented cases that resulted in permanent neonatal damage. Literary reports of shoulder dystocia indicate that the incidence of shoulder dystocia has increased in the USA about fourfold since the middle of the twentieth century. No comparable trend has been reported from most other countries. Study of head-to-body delivery times revealed that more than two-thirds of all injured fetuses had been extracted from the birth canal within 2 minutes. Incidents of shoulder dystocia began to escalate in the USA during the 1980s, shortly after the introduction of "active management" of the birthing process. This new technique replaced a conservative philosophy which had recommended abstinence from intervention on the part of the accoucheur. The authors consider the interventionist approach largely responsible for the exponential increase in the rates of shoulder dystocia in the USA. They recommend adherence to the traditional method of delivery on the part of obstetricians in Europe and elsewhere.

To examine injuries among pediatric patients treated in an emergency department (ED) related to contact with a fireplace. Data were obtained from the National Electronic Injury Surveillance System for the years 2002 through 2007. National estimates of ED visits for injuries associated with fireplaces were analyzed. Average annual rates were calculated, and logistic regression analyses were used to determine risk estimates for patient demographic characteristics related to ED visits for injuries associated with fireplaces. From 2002 through 2007, there were an estimated 8000 ED visits annually for injuries related to fireplaces in the United States, with an average annual rate of 18.8 ED visits per 100,000 children aged birth through 10 years. The most common injuries involved lacerations (66%), burns (10%), and contusions (10%). Most injuries occurred to the face (46%) or head (31%). Most patients (98%) were treated and released the same day. Results of logistic regression analyses revealed that children aged birth to 3 years (odds ratio, 12.2; 95% confidence interval, 9.1-16.5) and children aged 4 to 6 years (odds ratio, 4.8; 95% confidence interval, 3.5-6.5) were more likely present in an ED for a fireplace-related injury when compared with older children aged 7 to 10 years. Further research is warranted in the areas of etiology, injury prevention interventions, health communications, and surveillance to facilitate more effective injury prevention efforts.

Muscle pathology of the arm and forearm in brachial plexus birth injury (BPBI) with elbow flexion contracture has not been evaluated with MRI. To determine whether limited range of motion of the elbow in BPBI is correlated with specific patterns of muscular pathology. For 15 BPBI patients, total active motion (TAM) of the elbow (extension-flexion) and the forearm (pronation-supination) were measured. MRI of the elbow joints and musculature allowed assessment of elbow congruency. Fatty infiltration and size reduction of the muscles were graded semiquantitatively. Mean TAM of the elbow was 113 (50 -140 ) and that of the forearm 91 (10 -165 ). The greater the size reduction of the brachioradialis muscle, the more diminished was elbow TAM. The more extensive the BPBI and muscle pathology of the pronator teres muscle, the more limited was the TAM of the forearm. Pathology of the supinator and brachialis muscles was evident in every patient. Extensive BPBI may result in marked limitation of TAM. Elbow flexion contracture seems to be caused mainly by brachialis muscle pathology. Prosupination of the forearm is better preserved when the pronator teres is not severely affected. MRI can reliably show the extent of muscle pathology in BPBI. (orig.)

Background: Brain injury during the neonatal period has potentially lifelong consequences for a child. Perinatal infections and inflammation can induce preterm birth and unfavorable cognitive development, Thus inflammation has received enthusiastic interest for potential therapeutic approaches seeking to protect the newborn brain. Experimental evidence demonstrates that inflammation induces brain injury succeeding the initial insult. A key cytokine in brain injury is the tumor necrosis factor...

Population data are often used to monitor severe perineal trauma trends and investigate risk factors. Within New South Wales (NSW), two different datasets can be used, the Perinatal Data Collection ('birth' data) or a linked dataset combining birth data with the Admitted Patient Data Collection ('hospital' data). Severe perineal trauma can be ascertained by birth data alone, or by hospital International Classification of Diseases Australian Modification (ICD-10-AM) diagnosis and procedure coding in the linked dataset. The aim of this study was to compare rates and risk factors for severe perineal trauma using birth data alone versus using linked data. The study population consisted of all vaginal births in NSW between 2001 and 2011. Perineal injury coding in birth data was revised in 2006, so data were analysed separately for 2001-06 and 2006-11. Rates of severe perineal injury over time were compared in birth data alone versus linked data. Kappa and agreement statistics were calculated. Risk factor distributions (maternal age, primiparity, instrumental birth, birthweight ≥4 kg, Asian country of birth and episiotomy) were compared between women with severe perineal trauma identified by birth data alone, and those identified by linked data. Multivariable logistic regression was used to calculate the adjusted odds ratios (aORs) of severe perineal trauma. Among 697 202 women with vaginal births, 2.1% were identified with severe perineal trauma by birth data alone, and 2.6% by linked data. The rate discrepancy was higher among earlier data (1.7% for birth data, 2.4% for linked data). Kappa for earlier data was 0.78 (95% CI 0.78, 0.79), and 0.89 (95% CI 0.89, 0.89) for more recent data. With the exception of episiotomy, differences in risk factor distributions were small, with similar aORs. The aOR of severe perineal trauma for episiotomy was higher using linked data (1.33, 95% CI 1.27, 1.40) compared with birth data (1.02, 95% CI 0.97, 1.08). Although discrepancies

Despite improvements in survival of premature infants, many have comorbid conditions. The role of the kidney in multiorgan dysfunction is unclear, particularly in regard to intraventricular hemorrhage (IVH). We hypothesized that infants diagnosed with acute kidney injury (AKI) have an increased risk of IVH independent of gestational age (GA) and other variables associated with both comorbidities. This prospective cohort study consisted of 125 infants with a birth weight ≤1,200 g and/or GA ≤31 weeks. A definition of AKI was used from KDIGO, not including urine output as nonoliguria is common in this population. IVH was based on serial head ultrasounds. Neonates with AKI had a higher trend towards having IVH compared to those without [14/35 (40%) vs. 22/83 (26.5%), p = 0.1]. Infants with AKI were more likely to have stage 2 IVH or higher than those without AKI [12/36 (33.3%) vs. 6/82 (7.3%); p < 0.01]. AKI was associated with a 3.6-fold increased risk of a grade 2 or higher IVH [hazard ratio (HR) 3.55, 95% confidence interval (CI) 1.39-9.07] and over 4-fold increase in risk of a grade 3 or higher IVH (HR 4.34, 95% CI 1.43-13.21). While there was no association between AKI and IVH overall, those with AKI had a higher hazard ratio to develop a grade 2 or higher IVH even when controlling for birth weight, antenatal steroid use, and 5-min Apgar score. Future studies are indicated to expand sample size and to control for other clinical variables that could be associated with both AKI and IVH. © 2016 S. Karger AG, Basel.

OBJECTIVE: The objective of this study is to investigate the validity and the reliability of Birth Satisfaction Scale (BSS) and to adapt it into the Turkish language. This scale is used for measuring maternal satisfaction with birth in order to evaluate women’s birth perceptions. METHODS: In this study there were 150 women who attended to inpatient postpartum clinic. The participants filled in an information form and the BSS questionnaire forms. The properties of the scale were tested by conducting reliability and validation analyses. RESULTS: BSS entails 30 Likert-type questions. It was developed by Hollins Martin and Fleming. Total scale scores ranged between 30–150 points. Higher scores from the scale mean increases in birth satisfaction. Three overarching themes were identified in Scale: service provision (home assessment, birth environment, support, relationships with health care professionals); personal attributes (ability to cope during labour, feeling in control, childbirth preparation, relationship with baby); and stress experienced during labour (distress, obstetric injuries, receiving sufficient medical care, obstetric intervention, pain, prolonged labour and baby’s health). Cronbach’s alfa coefficient was 0.62. CONCLUSION: According to the present study, BSS entails 30 Likert-type questions and evaluates women’s birth perceptions. The Turkish version of BSS has been proven to be a valid and a reliable scale. PMID:28058355

Healing patterns of clavicular birth injuries as a guide to fracture dating in cases of possible infant abuse

2014-01-01

Dating fractures is critical in cases of suspected infant abuse. There are little scientific data to guide radiologists, and dating is generally based on personal experience and conventional wisdom. Since birth-related clavicular fractures are not immobilized and their age is known, we propose that an assessment of these injuries may serve as a guide for dating inflicted fractures in young infants, acknowledging that patterns observed in the clavicle may not be entirely generalizable to other bones injured in the setting of abuse. One hundred thirty-one radiographs of presumed birth-related clavicular fractures in infants between 0 and 3 months of age were reviewed by two pediatric radiologists with 30 and 15 years' experience. Readers were asked to evaluate images based on several parameters of fracture healing, with a focus on subperiosteal new bone formation (SPNBF) and callus formation. SPNBF and callus were each evaluated with regard to presence, thickness and character. Responses were correlated with known fracture ages. SPNBF was rarely seen in fractures less than 7 days old and was most often present by 10 days. Callus formation was rarely seen in fractures less than 9 days old and was most often present by 15 days. SPNBF thickness increased with fracture age and the character of SPNBF evolved from single-layered to solid/multilayered. Callus thickness decreased with fracture age and callus matrix evolved from soft to intermediate to hard in character. There is an evolution in clavicular fracture healing in young infants that follows a predictable pattern. These findings afford the prospect that predictable patterns of infant clavicular fracture healing can provide an evidence base that may be applicable in cases of suspected infant abuse. (orig.)

Healthcare system intervention for prevention of birth injuries – process evaluation of self-assessment, peer review, feedback and agreement for change

Science.gov (United States)

2012-01-01

Background Patient safety is fundamental in high quality healthcare systems but despite an excellent record of perinatal care in Sweden some children still suffer from substandard care and unnecessary birth injuries. Sustainable patient safety improvements assume changes in key actors’ mental models, norms and culture as well as in the tools, design and organisation of work. Interventions positively affecting team mental models on safety issues are a first step to enhancing change. Our purpose was to study a national intervention programme for the prevention of birth injuries with the aim to elucidate how the main interventions of self-assessment, peer review, feedback and written agreement for change affected the teams and their mental model of patient safety, and thereby their readiness for change. Knowledge of relevant considerations before implementing this type of patient safety intervention series could thereby be increased. Methods Eighty participants in twenty-seven maternity units were interviewed after the first intervention sequence of the programme. A content analysis using a priori coding was performed in order to relate results to the anticipated outcomes of three basic interventions: self-assessment, peer review and written feedback, and agreement for change. Results The self-assessment procedure was valuable and served as a useful tool for elucidating strengths and weaknesses and identifying areas for improvement for a safer delivery in maternity units. The peer-review intervention was appreciated, despite it being of less value when considering the contribution to explicit outcome effects (i.e. new input to team mental models and new suggestions for actions). The feedback report and the mutual agreement on measures for improvements reached when signing the contract seemed exert positive pressures for change. Conclusions Our findings are in line with several studies stressing the importance of self-evaluation by encouraging a thorough review of

Molecular Mechanisms of Neonatal Brain Injury

Directory of Open Access Journals (Sweden)

Claire Thornton

2012-01-01

Full Text Available Fetal/neonatal brain injury is an important cause of neurological disability. Hypoxia-ischemia and excitotoxicity are considered important insults, and, in spite of their acute nature, brain injury develops over a protracted time period during the primary, secondary, and tertiary phases. The concept that most of the injury develops with a delay after the insult makes it possible to provide effective neuroprotective treatment after the insult. Indeed, hypothermia applied within 6 hours after birth in neonatal encephalopathy reduces neurological disability in clinical trials. In order to develop the next generation of treatment, we need to know more about the pathophysiological mechanism during the secondary and tertiary phases of injury. We review some of the critical molecular events related to mitochondrial dysfunction and apoptosis during the secondary phase and report some recent evidence that intervention may be feasible also days-weeks after the insult.

Home birth after hospital birth: women's choices and reflections.

Science.gov (United States)

Bernhard, Casey; Zielinski, Ruth; Ackerson, Kelly; English, Jessica

2014-01-01

The number of US women choosing home birth is increasing. Little is known about women who choose home birth after having experienced hospital birth; therefore, the purpose of this research was to explore reasons why these women choose home birth and their perceptions regarding their birth experiences. Qualitative description was the research design, whereby focus groups were conducted with women who had hospital births and subsequently chose home birth. Five focus groups were conducted (N = 20), recorded, and transcribed verbatim. Qualitative content analysis was undertaken allowing themes to emerge. Five themes emerged from the women's narratives: 1) choices and empowerment: with home birth, women felt they were given real choices rather than perceived choices, giving them feelings of empowerment; 2) interventions and interruptions: women believed things were done that were not helpful to the birth process, and there were interruptions associated with their hospital births; 3) disrespect and dismissal: participants believed that during hospital birth, providers were more focused on the laboring woman's uterus, with some experiencing dismissal from their hospital provider when choosing to birth at home; 4) birth space: giving birth in their own home, surrounded by people they chose, created a peaceful and calm environment; and 5) connection: women felt connected to their providers, families, newborns, and bodies during their home birth. For most participants, dissatisfaction with hospital birth influenced their subsequent decision to choose home birth. Despite experiencing challenges associated with this decision, women expressed satisfaction with their home birth. © 2014 by the American College of Nurse-Midwives.

To characterize the MR findings of hypoxic-ischemic brain injury and to assess the value of the MR imaging. SE T1-, T2-weighted, and IR brain MR images of 44 infants and children with the past history of perinatal hypoxic insults were reviewed. Abnormal brain MR findings of 8 patients with birth history of prematurity and 36 patients with birth history of full-term/posterm including 7 with severe anoxic insult history, were compared in regard to the location and the character of the lesions. MRI demonstrated the followings; (1)abnormal signal intensity lesions of subcortical and/or deep cerebral white matter, cortex, and deep gray matter, (2)atrophy of the cerebral white matter, cortex and corpus callosum, with/without ventriculomegaly, and (3)delay in myelination. Periventricular and deep white matter lesions were demonstrated in the prematurity, the deep white matter lesions and/ or subcortical white matter lesions in the term/post-term, and deep gray matter lesions in the 7 patients with severe anoxic insults history. MR imaging was useful in the diagnosis of the hypoxic-ischemic brain injury, and the white and gray matter lesions were correlated with the time of the injury and the severity of hypoxic insult

Additional demographic data were collected using electronic linkages (Qualtrics ™ ). a convenience sample of childbearing women (n=2229) who had planned to birth in their home or birth center from the US (United States) participated. Participants were recruited via professional and personal contacts, primarily their midwives. the total 30-item BSS score mean was 128.98 (SD 16.92) and the 10-item BSS-R mean score was 31.94 (SD 6.75). Sub-scale mean scores quantified the quality of care provision, women's personal attributes, and stress experienced during labour. Satisfaction was higher for women with vaginal births compared with caesareans deliveries. In addition, satisfaction was higher for women who had both planned to deliver in a home or a birth centre, and who had actually delivered in a home or a birth center. total and subscale birth satisfaction scores were positive and high for the overall sample IMPLICATIONS FOR PRACTICE: the BSS and the BSS-R provide a robust tool to quantify women's experiences of childbirth between variables such as birth types, birth settings and providers.

Invitations to participate were posted in five different Internet forums for women on maternity leave, from September 2014 to August 2015. the sample comprised 381 post partum healthy women above the age of 20, during their maternity leave. Of the participants: 22% gave birth at home, 32% gave birth naturally in a hospital, and 46% of the participants had a medical birth at the hospital. life Orientation Test Revised (LOT-R), General Self-Efficacy Scale, Sense of Mastery Scale, Childbirth Experience Questionnaire (CEQ). women having had natural births, whether at home or at the hospital, significantly differed from women having had medical births in all aspects of the birth experience, even when controlling for age and optimism. Birth types contributed to between 14% and 24% of the explained variance of the various birth experience aspects. home and natural hospital births were associated with a better childbirth experience. Optimism was identified as a resilience factor, associated both with preference as well as with childbirth experience. physically healthy and resilient women could be encouraged to explore the prospect of home or natural hospital births as a means to have a more positive birth experience.

The aim of the study was to assess the effect of a birth-chair on obstetric outcome. We reviewed the hospital records of 220 consecutive pregnant women who gave birth on a birth-chair at our institution. The control group consisted of 440 pregnant women who preceded and followed the index cases and who had spontaneous vaginal deliveries in the conventional dorsal supine position. The controls were matched for parity and for the attending mid-wife. Patients who delivered in the birth-chair had significantly lower rates of episiotomy and manual separation of the placenta. The umbilical blood cord pH was significantly higher in neonates of the birth-chair group. The duration of labour, rate of perineal and vaginal injury, Apgar scores and rate of admission to a neonatal intermediate care unit were not influenced by the mode of delivery. Our data support previous studies that a birth-chair delivery may be a safe alternative to conventional delivery in the supine position.

Sucralfate is widely used as a cytoprotective agent in patients with peptic ulcer and other intestinal mucosal injury. The aim of this study is to investigate whether sucralfate has any effect on the prevention and treatment of hypoxia/reoxygenation-induced intestinal injury. Four groups of 10 1-day-old rat pups were studied. Hypoxia/reoxygenation (H/O)-induced intestinal injury was created. Group 1 was subjected to H/O just after birth and sacrificed at the end of the third day (Treatment Control). Group 2 was subjected to H/O just after birth and treated with sucralfate for 3 days. They were sacrificed at the end of the third day (Treatment). Group 3 was subjected to H/O on the third day after birth and then sacrificed (Prophylaxis Control). Group 4 was treated with sucralfate for the first 3 days, then H/O was created. Just after H/O, the pups were sacrificed (Prophylaxis). The intestinal tissues were harvested for histopathological investigation. Malondialdehyde (MDA) levels in the intestinal tissues were determined. The mucosal injury grades of the treatment and prophylaxis groups were significantly lower than those of control groups (p<0.05). The mean MDA level in the treatment and prophylaxis groups were 0.42+/-0.17 and 0.21+/-0.23 nmol/mg respectively. The MDA levels of both groups were significantly lower than in the control groups (p<0.05). The present study shows that sucralfate has beneficial effects in an experimental model of hypoxia/reoxygenation-induced intestinal injury.

MRI is invaluable in assessing the neonatal brain following suspected perinatal injury. Good quality imaging requires adaptations to both the hardware and the sequences used for adults or older children. The perinatal and postnatal details often predict the pattern of lesions sustained and should be available to aid interpretation of the imaging findings. Perinatal lesions, the pattern of which can predict neurodevelopmental outcome, are at their most obvious on conventional imaging between 1 and 2 weeks from birth. Very early imaging during the first week may be useful to make management decisions in ventilated neonates but brain abnormalities may still be subtle using conventional sequences. Diffusion-weighted imaging (DWI) is very useful for the early identification of ischaemic tissue in the neonatal brain but may underestimate the final extent of injury, particularly basal ganglia and thalamic lesions. MR imaging is an excellent predictor of outcome following perinatal brain injury and can therefore be used as a biomarker in interventional trials designed to reduce injury and improve neurodevelopmental outcome.

United States Army military police (MP) training is a 19-week course designed to introduce new recruits to basic soldiering skills, Army values and lifestyle, and law enforcement skills and knowledge. The present investigation examined injury rates and injury risk factors in MP training. At the start of training, 1,838 male and 553 female MP recruits were administered a questionnaire containing items on date of birth, height, weight, tobacco use, prior physical activity, injury history, and menstrual history. Injuries during training were obtained from electronic medical records and the training units provided data on student graduation and attrition. Successfully graduating from the course were 94.3% of the men and 83.7% of the women. Experiencing at least one injury during training were 34.2% of the men and 66.7% of the women (risk ratio (women/men) = 1.95, 95% confidence interval = 1.79-2.13). Recruits were at higher injury risk if they reported that they were older, had smoked in the past, or had performed less frequent exercise or sports prior to MP training. Men were at higher injury risk if they reported a prior injury and women were at higher risk if they reported missing at least six menstrual cycles in the last year or had previously been pregnant. The present investigation was the first to identify injury rates and identify specific factors increasing injury risk during MP training.

Nasal birth trauma: a review of appropriate treatment.

LENUS (Irish Health Repository)

Cashman, E C

2012-02-01

The aetiology of nasal deformity has frequently included birth trauma. There is no consensus in the literature as to whether nasal surgery, in the form of closed reduction, is indicated in neonates. The majority of studies in the literature that advocate intervention have inadequate followup periods and there is a paucity of evidence for the adverse effects of conservative management. This case highlights the therapeutic dilemma posed by such nasal injuries in the neonate and, to the best of the authors\\' knowledge, at the time of writing, represents the earliest reported case in the literature of nasal deformity in the neonate. The term nasal deformity is used to denote deformity of the nasal pyramid, soft tissue, and septum. Three main aspects of neonatal nasal deformity are addressed including, firstly, if nasal deformity at birth needs to be addressed, secondly, if left unaltered, what the long-term effects are and, finally, if intervention alters the normal course of midfacial development.

To describe the risk factors and labor characteristics of Clavicular fracture (CF) and brachial plexus injury (BPI); and compare antenatal and labor characteristics and prognosis of obstetrical BPI associated with shoulder dystocia with obstetrical BPI not associated with shoulder dystocia. This retrospective study consisted of women who gave birth to an infant with a fractured clavicle or BPI between January 2009 and June 2013. Antenatal and neonatal data were compared between groups. The control group (1300) was composed of the four singleton vaginal deliveries that immediately followed each birth injury. A multivariable logistic regression model, with backward elimination, was constructed in order to find independent risk factors associated with BPI and CF. A subgroup analysis involved comparison of features of BPI cases with or without associated shoulder dystocia. During the study period, the total number of vaginal deliveries was 44092. The rates of CF, BPI and shoulder dystocia during the study period were 0,6%, 0,16% and 0,29%, respectively. In the logistic regression model, shoulder dystocia, GDM, multiparity, gestational age >42 weeks, protracted labor, short second stage of labor and fetal birth weight greater than 4250 grams increased the risk of CF independently. Shoulder dystocia and protracted labor were independently associated with BPI when controlled for other factors. Among neonates with BPI whose injury was not associated with shoulder dystocia, five (12.2%) sustained permanent injury, whereas one neonate (4.5%) with BPI following shoulder dystocia sustained permanent injury (p = 0.34). BPI not associated with shoulder dystocia might have a higher rate of concomitant CF and permanent sequelae.

Full Text Available Acute kidney injury (AKI is a common event in the neonatal intensive care unit (NICU, especially in extremely-low-birth-weight (ELBW infants. This cohort study investigated the incidence of and risk factors for AKI in ELBW infants and their overall survival at the postmenstrual age (PMA of 36 weeks.All ELBW infants admitted to our NICU between January 2010 and December 2013 were enrolled. Those who died prior to 72 hours of life, had congenital renal abnormality, or had only one datum of the serum creatinine (SCr level after the first 24 hours of life were excluded. The criteria used for the diagnosis of AKI was set according to the modified neonatal KDIGO AKI definition.AKI occurred in 56% of 276 infants. Specifically, stage 1, stage 2, and stage 3 AKI occurred in 30%, 17%, and 9% of ELBW infants, respectively. High-frequency ventilation support (adjusted odds ratio [OR]: 3.4, 95% confidence interval [CI]: 1.78-6.67, p< 0.001, the presence of patent ductus arteriosus (adjusted OR: 4.3, 95% CI: 2.25-8.07, p < 0.001, lower gestational age (adjusted OR for gestational age: 0.7, 95% CI: 0.58-0.83, < 0.001, and inotropic agent use (adjusted OR: 2.6, 95% CI: 1.31-5.21, p = 0.006 were independently associated with AKI. Maternal pre-eclampsia was a protective factor (adjusted OR: 0.4, 95% CI: 0.14-0.97, p = 0.044. Infants with AKI had higher mortality before the PMA of 36 weeks with an adjusted hazard ratio (HR of 5.34 (95% CI: 1.21-23.53, p = 0.027. Additionally, infants with stage 3 AKI had a highest HR of 10.60, 95% CI: 2.09-53.67, p = 0.004.AKI was a very common event (56% in ELBW infants and was associated with a lower GA, high-frequency ventilation support, the presence of PDA, and inotropic agent use. AKI reduced survival of ELBW infants before the PMA of 36 weeks.

Birth weight and stuttering: Evidence from three birth cohorts.

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

With the advent of electronic records, the opportunity to conduct research on workplace-related injuries and musculoskeletal disorders has increased dramatically. The purpose of this study was to examine the United States Air Force Civil Engineering career field to determine if they are negatively impacted by their work environment. Specifically, the objective of this study was to determine if enlisted Civil Engineering Airmen (n = 25,385) were at increased risk for injury or injury-related musculoskeletal disorders compared to enlisted Information Management/Communications Airmen (n = 28,947). Using an historical prospective design, electronic data were assembled and analyzed using Cox's proportional hazards modeling. Models were stratified by gender and adjusted for race/ethnicity, marital status, birth year, and deployment status. Male Civil Engineers were observed to be at greater risk for both inpatient injury-related musculoskeletal disorders (HR = 1.86; 95% CI = 1.54-2.26) and injuries (HR = 1.77; 95% CI = 1.48-2.11), while female Civil Engineers were more than double the risk for both inpatient injury-related musculoskeletal disorders (HR = 2.18; 95% CI = 1.28-3.73) and injuries (HR = 2.22; 95% CI = 1.27-3.88) compared to Information Management/Communications Airmen. Although analyses do not allow exploration of specific causes, they highlight the utility of using electronic data to identify occupations for further evaluation. Based on these results, additional resources were allocated to survey Civil Engineers on their physical work demands and job requirements to identify key problem areas for further study and mitigation.

the objective of this study was to describe and compare perinatal and neonatal outcomes of women who received care from independent midwives practicing home births and at birth centres in Tokyo. a retrospective cohort study. birth centres and homes serviced by independent midwives in Tokyo. of the 43 eligible independent midwives 19 (44%) (10 assisted birth at birth centres, nine assisted home birth) participated in the study. A total of 5477 women received care during their pregnancy and gave birth assisted by these midwives between 2001 and 2006. researchers conducted a retrospective chart review of women's individual data. Collected data included demographic characteristics, process of pregnancy and perinatal and neonatal outcomes. We also collected data about independent midwives and their practice. of the 5477 women, 83.9% gave birth at birth centres and 16.1% gave birth at home. The average age was 31.7 years old and the majority (70.6%) were multiparas. All women had vaginal spontaneous deliveries, with no vacuum, forceps or caesarean section interventions. No maternal fatalities were reported, nor were breech or multiple births. The average duration of the first and second stages of labour was 14.9 hours for primiparas and 6.2 hours for multiparas. Most women (97.1%) gave birth within 24 hours of membrane rupture. Maternal position during labour varied and family attended birth was common. The average blood loss was 371.3mL, while blood loss over 500mL was 22.6% and over 1000mL was 3.6%. Nearly 60% of women had intact perinea. There were few preterm births (0.6%) and post mature births (1.3%). Infant's average birth weight was 3126g and 0.5% were low-birthweight-infants, while 3.3% had macrosomia. Among primiparas, the birth centre group had more women experiencing an excess of 500mL blood loss compared to the home birth group (27.2% versus 17.6% respectively; RR 1.54; 95%CI 1.10 to 2.16). Multiparas delivering at birth centres were more likely to have a

To obtain the low birth weight (LBW) rate, the very low birth weight (VLBW) rate, and gestational age (GA)-specific birth weight distribution based on a large population in Korea, we collected and analyzed the birth data of 108,486 live births with GA greater than 23 weeks for 1 yr from 1 January to 31 December 2001, from 75 hospitals and clinics located in Korea. These data included birth weight, GA, gender of the infants, delivery type, maternal age, and the presence of multiple pregnancy. The mean birth weight and GA of a crude population are 3,188 +/-518 g and 38.7+/-2.1 weeks, respectively. The LBW and the VLBW rates are 7.2% and 1.4%, respectively. The preterm birth rate (less than 37 completed weeks of gestation) is 8.4% and the very preterm birth rate (less than 32 completed weeks of gestation) is 0.7%. The mean birth weights for female infants, multiple births, and births delivered by cesarean section were lower than those for male, singletons, and births delivered vaginally. The risk of delivering LBW or VLBW infant was higher for the teenagers and the older women (aged 35 yr and more). We have also obtained the percentile distribution of GA-specific birth weight in infants over 23 weeks of gestation.

Children's and adolescents' injuries are a serious medical problem, as they lead to substantial medical and socio-economic effects. Aim of the paper. The aim of the conducted research was to analyze incidence and causes of hospitalizing children between birth and 18 years of age on the grounds of injuries. Material and methods. Medical histories of 2 832 children between birth and 18 years of age treated for injuries in 2006-2010 in Wladyslaw Bieganski Regional Specialist Hospital in Grudziadz were analyzed. Results. Correlations between treatment method and subsequent years of research (p<0,05, between children's age group and type of injury, and between type of injury and season of the year and hospitalization time, were shown to be statistically significant. No correlation was found in the studied population between subsequent years of research and injury types or residence of the injured. Conclusions. 1. The most frequent causes for placing children in the hospital were cranioencephalic injuries, injuries to the osteoarticular system, and burns. 2. The children's age determined the type of injury inflicted. Children in the youngest age group were most frequently hospitalized for burns, children in the age of 3-6 years for foreign bodies, and in the group of 7-18 years of age for injuries to the chest and to the osteoarticular system. 3. Boys were more frequently injured in a manner requiring hospital treatment than girls were. 4. A decisive majority of injured children required only conservative treatment and a stay in the hospital for no more than 3 days. 5. A constant tendency of higher occurence of injuries in children during spring and summer, was observed. Keywords: children, injuries

Cerebellar injury in preterm infants.

Although preterm birth is best known to result in adverse neurodevelopmental outcomes through injury of the supratentorial structures, including intraventricular hemorrhage and periventricular leukomalacia, the cerebellum has become increasingly recognized as an important target for injury and adverse motor and cognitive outcomes. Undergoing the most dramatic growth during the preterm period, the cerebellum is vulnerable to large and small hemorrhages, as well as hypoplasia resulting from a number of potentially modifiable risk factors. These factors include contact with intraventricular blood, crossed cerebrocerebellar diaschisis, postnatal glucocorticoid exposure, pain and opioid exposure, nutrition and somatic growth, cardiorespiratory factors, and socioeconomic status. Strategies targeting these factors may result in prevention of the motor and cognitive deficits seen after cerebellar hemorrhage or hypoplasia. Copyright © 2018 Elsevier B.V. All rights reserved.

In Belgium, very few women give birth outside the delivery room. In the United Kingdom and in the Netherlands, they are more numerous. Several studies evaluated obstetric and neonatal outcomes of home births compared with hospital births. We selected seven recent and large studies (with cohorts of more than 5.000 women) using PubMed, Science Direct and Cochrane Database of Systematic Reviews. Several questions were examined. Is there any difference in maternal and neonatal outcomes depending on the intended place of birth? Does parity affect outcomes ? What are the characteristics of women who choose to deliver at home ? We conclude that giving birth at home improves obstetric outcomes but is riskier for the baby, especially for the first one. The women delivering at home are mainly white Europeans, between 25 and 35 years old, in a relationship, multiparous and wealthier. In order to avoid this increased risk for the baby while preserving the obstetric advantages, alongside birth centers offer an intermediate solution. They combine the reassuring home-like atmosphere with the safety of the hospital. In Belgium, the first alongside birth center " Le Cocon " (a low technicity unit distinct from the delivery room) offers now this type of alternative place of birth for women in Hôpital Erasme in Brussels.

Early biomarkers and potential mediators of ventilation-induced lung injury in very preterm lambs

Directory of Open Access Journals (Sweden)

Davis Peter G

2009-03-01

Full Text Available Abstract Background Bronchopulmonary dysplasia (BPD is closely associated with ventilator-induced lung injury (VILI in very preterm infants. The greatest risk of VILI may be in the immediate period after birth, when the lungs are surfactant deficient, still partially filled with liquid and not uniformly aerated. However, there have been very few studies that have examined this immediate post-birth period and identified the initial injury-related pathways that are activated. We aimed to determine if the early response genes; connective tissue growth factor (CTGF, cysteine rich-61 (CYR61 and early growth response 1 (EGR1, were rapidly induced by VILI in preterm lambs and whether ventilation with different tidal volumes caused different inflammatory cytokine and early response gene expression. Methods To identify early markers of VILI, preterm lambs (132 d gestational age; GA, term ~147 d were resuscitated with an injurious ventilation strategy (VT 20 mL/kg for 15 min then gently ventilated (5 mL/kg for 15, 30, 60 or 120 min (n = 4 in each. To determine if early response genes and inflammatory cytokines were differentially regulated by different ventilation strategies, separate groups of preterm lambs (125 d GA; n = 5 in each were ventilated from birth with a VT of 5 (VG5 or 10 mL/kg (VG10 for 135 minutes. Lung gene expression levels were compared to levels prior to ventilation in age-matched control fetuses. Results CTGF, CYR61 and EGR1 lung mRNA levels were increased ~25, 50 and 120-fold respectively (p CTGF, CYR61, EGR1, IL1-β, IL-6 and IL-8 mRNA levels compared to control levels. CTGF, CYR61, IL-6 and IL-8 expression levels were higher in VG10 than VG5 lambs; although only the IL-6 and CYR61 mRNA levels reached significance. Conclusion CTGF, CYR61 and EGR1 may be novel early markers of lung injury and mechanical ventilation from birth using relatively low tidal volumes may be less injurious than using higher tidal volumes.

Permissive hypercapnia is a respiratory-care strategy that is used to reduce the risk for lung injury. The goal of this study was to evaluate whether permissive hypercapnia is associated with higher risk for intraventricular hemorrhage and early childhood behavioral and functional problems than normocapnia among very low birth weight infants. Very low birth weight infants from a statewide cohort were eligible for this study when they were born at <32 weeks' gestational age and survived at least 24 hours. Infants were classified as receiving a permissive hypercapnia, normocapnia, or unclassifiable respiratory strategy during the first 24 hours after birth according to an algorithm based on Pco(2) values and respiratory-treatment decisions that were abstracted from medical charts. Intraventricular hemorrhage diagnosis was also abstracted from the medical chart. Behavioral and functional outcomes were assessed by parent interview at 2 to 3 years. Logistic regression was used to evaluate the relationship between intraventricular hemorrhage and respiratory strategy; ordinary linear regression was used to evaluate differences in behavior and function scores between children by respiratory strategy. Infants who received a permissive hypercapnia strategy were not more likely to have intraventricular hemorrhage than those with normocapnia. There were no differences in any of the behavioral or functional scores among children according to respiratory strategy. There was a significant interaction between care strategy and 1-minute Apgar score, indicating that infants with lower Apgar scores may be at higher risk for intraventricular hemorrhage with permissive hypercapnia. This study suggests that permissive hypercapnia does not increase risk for brain injury and impairment among very low birth weight children. The interaction between respiratory strategy and Apgar score is a potential worrisome exception to this conclusion. Future research should further evaluate the effect

We evaluated the birth outcomes of planned home births. We conducted a retrospective cohort study using Missouri vital records from 1989 to 2005 to compare the risk of newborn seizure and intrapartum fetal death in planned home births attended by physicians/certified nurse midwives (CNMs) or non-CNMs with hospitals/birthing center births. The study sample included singleton pregnancies between 36 and 44 weeks of gestation without major congenital anomalies or breech presentation ( N = 859,873). The adjusted odds ratio (aOR) of newborn seizures in planned home births attended by non-CNMs was 5.11 (95% confidence interval [CI]: 2.52, 10.37) compared with deliveries by physicians/CNMs in hospitals/birthing centers. For intrapartum fetal death, aORs were 11.24 (95% CI: 1.43, 88.29), and 20.33 (95% CI: 4.98, 83.07) in planned home births attended by non-CNMs and by physicians/CNMs, respectively, compared with births in hospitals/birthing centers. Planned home births are associated with increased likelihood of adverse birth outcomes. © Thieme Medical Publishers.

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

This study determined the profile and birthing practices in both modern and traditional ways among Maranao traditional birth attendants (TBAs) in Lanao del Norte, Philippines. It employed a descriptive research design. The respondents were 50 Maranao TBAs selected through the snowball sampling technique. A questionnaire was developed by the researchers to identify the respondents' modern birthing practices utilizing the Essential Intrapartum and Newborn Care (EINC) Protocol. To determine their profile and traditional birthing practices, items from a previous study and the respondents' personal claims were adapted. This study shows that Maranao TBAs have less compliance to the EINC Protocol and they often practice the traditional birthing interventions, thus increasing the risk of complications to both mother and newborn.

The birth of a baby is a family experience. However, in the United Kingdom birth often occurs outside the family environment, in hospital. Both home and hospital births have risks and benefits, but research shows that, for most women, it is as safe to give birth at home as it is in hospital. Women report home-birth to be satisfying with lowered risks of intervention and less likelihood of being separated from their family. It is also more cost effective for the National Health Service. Yet, whilst midwives are working hard to promote home birth as an option, it remains controversial. The aim of this paper is to raise awareness of the safety of home birth and the needs of women and midwives when a home birth is chosen. It provides an overview of care required and the role of the midwife in the ensuring care is woman-centred and personalised.

The aim of this study was to assess the risk of injuries among children exposed to a stressful life exposure (defined as bereavement) before conception or during fetal life. Population-based cohort study. Denmark. All singleton births in Denmark between 1 January 1995 and 31 December 2006 were identified. These newborns were then linked to mothers, fathers, grandparents and siblings using individually assigned civil personal registration numbers. We identified that data on childhood injuries were obtained from the Danish National Patient Registry, which contains data on all hospital stays and outpatient visits. Incidence rate ratios (IRRs) were estimated from birth using log-linear Poisson regression models, and person-years were used as the offset variable. Age, residence, calendar period, maternal education, maternal income and parental-cohabitation status are treated as time-dependent variables (records were extracted from the offspring's birth year). Exposure to maternal bereavement due to a father's death had the strongest association with childhood injuries, especially when the cause of death was due to a traumatic event (adjusted estimates of IRR (aIRR): 1.25, 95%CI: 0.99 to 1.58). We did not find an association for childhood injuries and maternal bereavement due to grandparent's death, and we only found an association for sibling death when restricting to deaths due to traumatic events (aIRR: 1.20, 95%CI:1.03 to 1.39). The aetiology of childhood injuries is complex and may be related to events that take place during prenatal life. This study suggests that exposure to a stressful life event during gestation may be linked to injury susceptibility in childhood. However, changes in postnatal family conditions related to loss or genetic factors may also play a role. Developmental plasticity related to early life exposures leading to disease programming in offspring is a theory with substantial theoretical and empirical support. Prenatal stress exposure has been

The natural history and management of brachial plexus birth palsy.

Science.gov (United States)

Buterbaugh, Kristin L; Shah, Apurva S

2016-12-01

Brachial plexus birth palsy (BPBP) is an upper extremity paralysis that occurs due to traction injury of the brachial plexus during childbirth. Approximately 20 % of children with brachial plexus birth palsy will have residual neurologic deficits. These permanent and significant impacts on upper limb function continue to spur interest in optimizing the management of a problem with a highly variable natural history. BPBP is generally diagnosed on clinical examination and does not typically require cross-sectional imaging. Physical examination is also the best modality to determine candidates for microsurgical reconstruction of the brachial plexus. The key finding on physical examination that determines need for microsurgery is recovery of antigravity elbow flexion by 3-6 months of age. When indicated, both microsurgery and secondary shoulder and elbow procedures are effective and can substantially improve functional outcomes. These procedures include nerve transfers and nerve grafting in infants and secondary procedures in children, such as botulinum toxin injection, shoulder tendon transfers, and humeral derotational osteotomy.

At 2.2 percent in 2012, the home birth rate in Iceland is the highest in the Nordic countries and has been rising rapidly in the new millennium. The objective of this study was to compare the outcomes of planned home births and planned hospital births in comparable low-risk groups in Iceland. The study is a retrospective cohort study comparing the total population of 307 planned home births in Iceland in 2005-2009 to a matched 1:3 sample of 921 planned hospital births. Regression analysis, adjusted for confounding variables, was performed for the primary outcome variables. The rate of oxytocin augmentation, epidural analgesia, and postpartum hemorrhage was significantly lower when labor started as a planned home birth. Differences in the rates of other primary outcome variables were not significant. The home birth group had lower rates of operative birth and obstetric anal sphincter injury. The rate of 5-minute Apgar score home and hospital birth groups, but the home birth group had a higher rate of neonatal intensive care unit admission. Intervention and adverse outcome rates in both study groups, including transfer rates, were higher among primiparas than multiparas. Oxytocin augmentation, epidural analgesia, and postpartum hemorrhage rates were significantly interrelated. This study adds to the growing body of evidence that suggests that planned home birth for low-risk women is as safe as planned hospital birth. © 2015 Wiley Periodicals, Inc.

It is widely perceived that home births and birth centers may help decrease the costs of maternity care for women with uncomplicated pregnancies and deliveries. This structured review examines the literature relating to the economic implications of home births and birth center care compared with hospital maternity care. The bibliographic databases MEDLINE (from 1950), CINAHL (from 1982), EMBASE (from 1980), and an "in-house" database, Econ2, were searched for relevant English language publications using MeSH and free text terms. Data were extracted with respect to the study design, inclusion criteria, clinical and cost results, and details of what was included in the cost calculations. Eleven studies were included from the United Kingdom, United States, Australia, and Canada. Two studies focused on home births versus other forms and locations of care, whereas nine focused on birth centers versus other forms and locations of care. Resource use was generally lower for women cared for at home and in birth centers due to lower rates of intervention, shorter lengths of stay, or both. However, this fact did not always translate into lower costs because, in the U.K. where many studies were conducted, more midwives of a higher grade were employed to manage the birth centers than are usually employed in maternity units, and because of costs of converting existing facilities into delivery rooms. The quality of much of the literature was poor, although no studies were excluded for this reason. Selection bias was likely to be a problem in those studies not based on randomized controlled trials because, even where birth center eligibility was applied throughout, women who choose to deliver at home or in a birth center are likely to be different in terms of expectations and approach from women choosing to deliver in hospital. This review highlights the paucity of economic literature relating to home births and birth centers. Differences in results between studies may be

Women who seek vaginal birth after cesarean delivery may find limited in-hospital options. Increasing numbers of women in the United States are delivering by vaginal birth after cesarean delivery out-of-hospital. Little is known about neonatal outcomes among those who deliver by vaginal birth after cesarean delivery in- vs out-of-hospital. The purpose of this study was to compare neonatal outcomes between women who deliver via vaginal birth after cesarean delivery in-hospital vs out-of-hospital (home and freestanding birth center). We conducted a retrospective cohort study using 2007-2010 linked United States birth and death records to compare singleton, term, vertex, nonanomolous, and liveborn neonates who delivered by vaginal birth after cesarean delivery in- or out-of-hospital. Descriptive statistics and multivariate regression analyses were conducted to estimate unadjusted, absolute, and relative birth-setting risk differences. Analyses were stratified by parity and history of vaginal birth. Sensitivity analyses that involved 3 transfer status scenarios were conducted. Of women in the United States with a history of cesarean delivery (n=1,138,813), only a small proportion delivered by vaginal birth after cesarean delivery with the subsequent pregnancy (n=109,970; 9.65%). The proportion of home vaginal birth after cesarean delivery births increased from 1.78-2.45%. A pattern of increased neonatal morbidity was noted in unadjusted analysis (neonatal seizures, Apgar score birthing their second child by vaginal birth after cesarean delivery in out-of-hospital settings had higher odds of neonatal morbidity and death compared with women of higher parity. Women who had not birthed vaginally prior to out-of-hospital vaginal birth after cesarean delivery had higher odds of neonatal morbidity and mortality compared with women who had birthed vaginally prior to out-of-hospital vaginal birth after cesarean delivery. Sensitivity analyses generated distributions of plausible

Planned and unplanned home births and hospital births in Calgary, Alberta, 1984-87.

1989-01-01

Information collected on all home births in Calgary (Canada) between the years 1984 and 1987, was examined and analyzed according to whether the home birth environment had been planned or unplanned. The two groups were compared to each other and to all hospital births according to demographic characteristics of mothers, indicators of prenatal care, and birth outcome. Mothers who had planned their home birth were more likely to be primiparous, attend prenatal classes, obtain regular prenatal care from a physician, and have babies with a higher birth weight than either the unplanned or hospital group. Of particular concern, however, were the subset of unplanned home births who were primiparous. These mothers attended prenatal classes less frequently than any other group, reported the lowest number of physician visits, were youngest, and least likely to be married. In addition their babies averaged the shortest gestational age and the lowest birth weight. Findings in general show that planned and unplanned home births must be considered as heterogeneous groups in any comparison of risk factors and of birth outcome between home and hospital births. Further, within the unplanned group, multiparous women differ from primiparous women. Given the limitations inherent in this and similar studies, the apparent better outcome in the planned home birth group, as measured by birth weight, must be viewed with caution.

Myelography and CT myelography (CMT) were reviewed in 18 cases of birth palsy with clinically suspected avulsion injury. Root-somatosensory evoked potential (root-SEP) was also reviewed for myelographic evaluation of the nerve root avolusion in birth palsy. Root-SEP is not induced in case of avulsed nerve roots, but is induced in case of both normal and incompletely avulsed roots. Myelography demonstrated 58 abnormal nerve roots in 18 cases (19 limbs); 45 (78%) complete and 13 (22%) incomplete nerve root avulsions. Each of complete and incomplete avulsions was defined as total absence and partial presence of rootlets on myelography, respectively. Traumatic meningoceles were detected at 46 roots (79%) on myelography and/or CTM; 35 roots on myelography and 45 roots on CTM. CTM could not detect only a very small meningocele at one root. At 11 roots CTM was superior to myelography in delineating a meningocele because CTM is sensitive to a poorly enhanced meningocele. CTM, however, could not diagnose nerve root avulsions so accurately as myelography, since myelography detected 12 (7 completely and 5 incompletely) avulsed roots without meningocele, whereas CTM could not delineate the nerve roots clearly. Thus, myelography is indispensable to evaluate nerve root avulsions without meningocele. Root-SEP was examined in 9 patients who underwent branchial plexus exploration. SEP was negative at 22/25 roots with complete avulsion and was positive at 7/7 roots with myelographically incomplete avulsion, regardless of presence or absence of any traumatic meningocele. Myelography and root-SEP correlated well at 29 (92%) out of 32 roots in evaluating complete and incomplete avulsion injuries. Myelography and root-SEP were not considered in 3 roots. Though myelography demonstrated complete avulsions with traumatic meningocele, SEP was positive in these three roots, which were interpreted as partially avulsed roots. (J.P.N.).

To determine the effects of infants' birth order, maternal age, and socioeconomic status (SES) on birth weight. This cross-sectional study included a sample of 858 mothers recruited over a 6-month period in 2010, in a defined population of 9 urban health centers, and who were admitted for their infants' first vaccination. Maternal clinical data, demographic data, and infants' birth weight were obtained from the interview and maternal hospital files. Multiple regression and analysis of variance were used for data analysis. First and fourth births had lower birth weights compared with second and third births in all maternal ages in controlling parity, birth weight increases with maternal age up to the early 24, and then tends to level off. Male gender, maternal age 20-24 years, second and third births had a significant positive effect on birth weight. Lower family economic status and higher educational attainment were significantly associated with lower birth weight. For women in the 15-19 and 40-44 years age groups, the second birth order was associated with the most undesirable effect on birth weight. Accessibility of health care services, parity, maternal age, and socioeconomic factors are strongly associated with infants' birth weight.

Full Text Available The study aimed to describe the experiences of a group of nurse-midwives from the city of Campinas, SP, Brasil, regarding the transition process from attending institutionalized births to attending home births, in the period 2011 – 2013. The study is of the experience report type; the reflections, perceptions and challenges experienced in this process were collected using the technique of brainstorming. Content analysis, as proposed by Bardin, was used, which yielded four thematic categories: a the hospital experience; b living with obstetric violence; c returning home and d the challenges of home care. It is concluded that attending home births offers greater satisfaction to the nurses, even in the face of various obstacles, as it is possible to offer a care to the woman and new-born which covers both the concept of comprehensiveness and the current scientific recommendations.

Reducing radiation exposure in newborns with birth head trauma

Full Text Available Background. Birth head trauma causing intracranial injury is one of the most common causes of neonatal mortality and morbidity. In case of suspected cranial fractures and intracranial hematomas, diagnostic methods involving radiation, such as x-ray radiography and computed tomography, are recommended. Recently, an increasing number of studies have highlighted the risk of cancer complications associated with computed tomography in infants. Therefore, diagnostic methods that reduce radiation exposure in neonates are important. One such method is ultrasonography (US. Aim. We evaluated US as a non-ionizing radiation method for diagnosis of cranial bone fractures and epidural hematomas in newborns with cephalohematomas or other birth head traumas. Material and methods. The study group included 449 newborns with the most common variant of birth head trauma: cephalohematomas. All newborns underwent transcranial-transfontanelle US for detection of intracranial changes and cranial US for visualization of bone structure in the cephalohematoma region. Children with ultrasonic signs of cranial fractures and epidural hematomas were further examined at a children’s hospital by x-ray radiography and/or computed tomography. Results and discussion. We found that cranial US for diagnosis of cranial fractures and transcranial-transfontanelle US for diagnosis of epidural hematomas in newborns were highly effective. In newborns with parietal cephalohematomas (444 children, 17 (3.8% had US signs of linear fracture of the parietal bone, and 5 (1.1% had signs of ipsilateral epidural hematoma. Epidural hematomas were visualized only when US was performed through the temporal bone and not by using the transfontanelle approach. Sixteen cases of linear fractures and all epidural hematomas were confirmed by computed tomography. Conclusion. The use of US diagnostic methods reduced radiation exposure in newborns with birth head trauma. US methods (transcranial

Between 1972 and 1993 the number of hospitals and maternity homes providing obstetric help in Norway fell from 158 to 67. Most of the decline is explained by the closing down of maternity homes and obstetrical units in small hospitals, partly due to a reduction in number of births and partly to a deliberate drive towards giving birth in larger units. 16 of the 19 counties of Norway contained four or fewer obstetric institutions in 1993. Nevertheless, most of the 60,000 births took place in institutions with between 500 and 2,999 births annually. Births at home accounted for 0.3%, and births during transport for 0.2% of the total in 1990 and 1993.

Posterior rib fractures in young children have a high positive predictive value for non-accidental injury (NAI). Combined data of five studies on birth trauma (115,756 live births) showed no cases of rib fractures resulting from birth trauma. There have, however, been sporadic cases reported in the literature. We present three neonates with both posterior rib fractures and ipsilateral clavicular fractures resulting from birth trauma. A review of the literature is also presented. The common denominator and a possible mechanical aetiology are discussed. In total, 13 cases of definitive birth-related posterior rib fractures were identified. Nearly all (9/10) posterior rib fractures were (as far as reported in the original publications) in the midline. In 12 of the 13 children, birth weight was high and in 7 children birth was complicated by shoulder dystocia. An interesting finding was that in cases where a clavicular fracture was present, this was on the ipsilateral side. Radiologists, when presented with a neonate with posterior rib fractures, should be aware of this rare differential diagnosis. (orig.)

This report presents preliminary data for 2005 on births in the United States. U.S. data on births are shown by age, live-birth order, race, and Hispanic origin of mother. Data on marital status, cesarean delivery, preterm births, and low birthweight (LBW) are also presented. Data in this report are based on 99.2 percent of births for 2005. The records are weighted to independent control counts of all births received in state vital statistics offices in 2005. Comparisons are made with 2004 data. The crude birth rate in 2005 was 14.0 births per 1,000 total population, unchanged from 2004. The general fertility rate, however, rose to 66.7 births per 1,000 women aged 15-44 years in 2005, the highest level since 1993. The birth rate for teenagers declined by 2 percent in 2005, falling to 40.4 births per 1,000 women aged 15-19 years, the lowest ever recorded in the 65 years for which a consistent series of rates are available. The rate declined for teenagers 15-17 years to 21.4 births per 1,000, but was essentially stable for older teenagers 18-19 years. The birth rate for women aged 20-24 years rose in 2005, whereas the rate for women aged 25-29 years was essentially unchanged. The birth rates for women aged 30 years and over rose to levels not seen in almost 40 years. Childbearing by unmarried women increased to record levels for the Nation in 2005. The birth rate rose 3 percent to 47.6 births per 1,000 unmarried women aged 15-44 years; the proportion of all births to unmarried women increased to 36.8 percent. The cesarean delivery rate rose by 4 percent in 2005 to 30.2 percent of all births, another record high for the Nation. The preterm birth rate continued to rise (to 12.7 percent in 2005) as did the rate for LBW births (8.2 percent).

Objective: To identify factors affecting birth weight and pre-term birth, and to find associations with electromagnetic devices such as television, computer and mobile phones. Methods: The study was conducted in Turkey at Gazintep University, Faculty of Medicine Outpatient Clinic at the Paediatric Ward. It comprised 500 patients who presented at the clinic from May to December 2009. All participants were administered a questionnaire regarding their pregnancy history. SPSS 13 was used for statistical analysis. Results: In the study, 90 (19%) patients had pre-term birth , and 64 (12.9%) had low birth weight rate Birth weight was positively correlated with maternal age and baseline maternal weight (r= 0.115, p= 0.010; r= 0.168, p=0.000, respectively). Pre-term birth and birth weight less than 2500g were more common in mothers with a history of disease during pregnancy (p=0.046 and p=0.008, respectively). The habit of watching television and using mobile phones and computer by mothers did not demonstrate any relationship with birth weight. Mothers who used mobile phones or computers during pregnancy had more deliveries before 37 weeks (p=0.018, p=0.034; respectively). Similarly, pregnancy duration was shorter in mothers who used either mobile phone or computers during pregnancy (p=0.005, p=0.048, respectively). Conclusion: Mobile phones and computers may have an effect on pre-term birth. (author)

The onset of mechanical ventilation is a critical time for the initiation of cerebral white matter (WM) injury in preterm neonates, particularly if they are inadvertently exposed to high tidal volumes (VT) in the delivery room. Protective ventilation strategies at birth reduce ventilation-induced lung and brain inflammation and injury, however its efficacy in a compromised newborn is not known. Chorioamnionitis is a common antecedent of preterm birth, and increases the risk and severity of WM injury. We investigated the effects of high VT ventilation, after chorioamnionitis, on preterm lung and WM inflammation and injury, and whether a protective ventilation strategy could mitigate the response. Pregnant ewes (n = 18) received intra-amniotic lipopolysaccharide (LPS) 2 days before delivery, instrumentation and ventilation at 127±1 days gestation. Lambs were either immediately euthanased and used as unventilated controls (LPSUVC; n = 6), or were ventilated using an injurious high VT strategy (LPSINJ; n = 5) or a protective ventilation strategy (LPSPROT; n = 7) for a total of 90 min. Mean arterial pressure, heart rate and cerebral haemodynamics and oxygenation were measured continuously. Lungs and brains underwent molecular and histological assessment of inflammation and injury. LPSINJ lambs had poorer oxygenation than LPSPROT lambs. Ventilation requirements and cardiopulmonary and systemic haemodynamics were not different between ventilation strategies. Compared to unventilated lambs, LPSINJ and LPSPROT lambs had increases in pro-inflammatory cytokine expression within the lungs and brain, and increased astrogliosis (pVentilation after acute chorioamnionitis, irrespective of strategy used, increases haemodynamic instability and lung and cerebral inflammation and injury. Mechanical ventilation is a potential contributor to WM injury in infants exposed to chorioamnionitis.

To examine the change in breastfeeding behaviors over time, among low birth weight (LBW), very low birth weight (VLBW), and normal birth weight (NBW) infants using nationally representative US data. Univariate statistics and bivariate logistic models were examined using the Early Child Longitudinal Study-Birth Cohort (2001) and National Study of Children's Health (2007 and 2011/2012). Breastfeeding behaviors improved for infants of all birth weights from 2007 to 2011/2012. In 2011/2012, a higher percentage of VLBW infants were ever breastfed compared with LBW and NBW infants. In 2011/2012, LBW infants had a 28% lower odds (95% CI, 0.57-0.92) of ever breastfeeding and a 52% lower odds (95% CI, 0.38-0.61) of breastfeeding for ≥6 months compared with NBW infants. Among black infants, a larger percentage of VLBW infants were breastfed for ≥6 months (26.2%) compared with LBW infants (14.9%). Breastfeeding rates for VLBW and NBW infants have improved over time. Both VLBW and NBW infants are close to meeting the Healthy People 2020 ever breastfeeding goal of 81.9%. LBW infants are farther from this goal than VLBW infants. The results suggest a need for policies that encourage breastfeeding specifically among LBW infants. Copyright © 2018 Elsevier Inc. All rights reserved.

The birth beliefs scale - a new measure to assess basic beliefs about birth.

Science.gov (United States)

Preis, Heidi; Benyamini, Yael

2017-03-01

Basic beliefs about birth as a natural and safe or a medical and risky process are central in the decisions on where and how to birth. Despite their importance, they have not been studied separately from other childbirth-related constructs. Our aim was to develop a measure to assess these beliefs. Pregnant Israeli women (N = 850, gestational week ≥14) were recruited in women's health centers, in online natural birth forums, and through home midwives. Participants filled in questionnaires including sociodemographic and obstetric background, the Birth Beliefs Scale (BBS), dispositional desire for control (DC) and planned mode of delivery. Factor analyses revealed that the BBS is composed of two factors: beliefs about birth as a natural process and beliefs about birth as a medical process. Both subscales showed good internal and test-retest reliability. They had good construct validity, predicted birth choices, and were weakly correlated with DC. Women's medical obstetric history was associated with the BBS, further supporting the validity of the scale. Beliefs about birth may be the building blocks that make up perceptions of birth and drive women's preferences. The new scale provides an easy way to distinctly assess them so they can be used to further understand planned birth behaviors. Additional studies are needed to comprehend how these beliefs form in different cultural contexts and how they evolve over time.

PLANNED HOME BIRTH: A REVIEW

Full Text Available Background: Home birth is as old as humanity, but still most middle- and high-income countries consider hospitals as the safest birth settings, as complications regarding birth are highly unpredictable. Despite this there are a few countries in which home birth in integrated into official healthcare system (the Netherlands, United Kingdom, Canada etc.. Home births can be divided into unplanned and planned, and the latter can be further categorized by the presence of the birth attendants. This review focuses on planned home births, which are differently represented throughout the world. In the United States 0.6-1.0% of all children are born at home, in the United Kingdom 2-3%, in Canada 1.6% and in the Netherlands 20-30%. For Slovenia, the number of planned home births is unknown; however, in 2010 0.1% of children were born outside medical facilities.Conclusions: The safety of home birth in still under the debate. While research confirms smaller number of obstetric interventions and some complications in mothers who give birth at home, the data regarding the neonatal and perinatal mortality and morbidity is still conflicting. This confirms the need for large multicentric trials in this field. Current home birth guidelines emphasize that women should be well informed regarding the possible advantages and disadvantages of home births. In addition, the emphasis is on definition of selection criteria for home birth, indications for intrapartal transfer to the hospital and appropriate education of birth attendants.

OBJECTIVES: We investigated the effect of family social and economic circumstances on intentional injury among adolescents. METHODS: We conducted a cross-sectional register study of youths aged 10 to 19 years who lived in Sweden between 1990 and 1994. We used socioeconomic status, number of parents...... in the household (1- or 2-parent home), receipt of welfare benefits, parental country of birth, and population density as exposures and compiled relative risks and population-attributable risks (PARs) for self-inflicted and interpersonal violence-related injury. RESULTS: For both genders and for both injury types......, receipt of welfare benefits showed the largest crude and net relative risks and the highest PARs. The socioeconomic status-related PAR for self-inflicted injury and the PAR related to number of parents in the household for interpersonal violence-related injury also were high.

Full Text Available The birth by caesarean section has become an expanding phenomenon in the recent years, natural births being more and more rare in Romania. The increasing incidence of these operations has been observed in the recent years, in the conditions of more effective fetal monitoring, modification of the malpractice law and increasing degree of information of the women. In Romania, depending on the hospital, the percentage of births by caesarean section ranges between 20-80%, even 90% (these latter percentage being valid especially in private clinics. The percentage of the operations is higher in big cities, and in Bucharest about 70% of the births are done by C-section. The World Health Organization recommends a maximum percentage surgical intervention of 10-15%. Fearing the labor pain, more and more women are choosing to bring their children into the world by Caesarean section. Also the number of doctors who claim that cesarean section is a better option is increasing. Both persons involved in the birth process have the responsibility of that decision - meaning both mother and doctor. The option of the mother is very important, but the recommendation of the doctor can make the difference. The decision is not only of the doctor, he just presents the information that the mother does not know, mother's wish being the most important. In this paper we conducted a study to determine the comparative costs of the vaginal births with those by Caesarean section. The retrospective study was conducted between 01.01.2015 - 31.12.2015, on 3607 births registered in the Obstetrics and Gynecology Clinics of Clinical Emergency County Hospital Oradea. Gemellary births were excluded from the study. We analyzed the comparative costs of a vaginal birth and of a birth by caesarean section in order to highlight the share of cesarean births compared to vaginal births.

Full Text Available Abstract Background Caesarean section rates in Brazil have been steadily increasing. In 2009, for the first time, the number of children born by this type of procedure was greater than the number of vaginal births. Caesarean section is associated with a series of adverse effects on the women and newborn, and recent evidence suggests that the increasing rates of prematurity and low birth weight in Brazil are associated to the increasing rates of Caesarean section and labour induction. Methods Nationwide hospital-based cohort study of postnatal women and their offspring with follow-up at 45 to 60 days after birth. The sample was stratified by geographic macro-region, type of the municipality and by type of hospital governance. The number of postnatal women sampled was 23,940, distributed in 191 municipalities throughout Brazil. Two electronic questionnaires were applied to the postnatal women, one baseline face-to-face and one follow-up telephone interview. Two other questionnaires were filled with information on patients’ medical records and to assess hospital facilities. The primary outcome was the percentage of Caesarean sections (total, elective and according to Robson’s groups. Secondary outcomes were: post-partum pain; breastfeeding initiation; severe/near miss maternal morbidity; reasons for maternal mortality; prematurity; low birth weight; use of oxygen use after birth and mechanical ventilation; admission to neonatal ICU; stillbirths; neonatal mortality; readmission in hospital; use of surfactant; asphyxia; severe/near miss neonatal morbidity. The association between variables were investigated using bivariate, stratified and multivariate model analyses. Statistical tests were applied according to data distribution and homogeneity of variances of groups to be compared. All analyses were taken into consideration for the complex sample design.

Midwife-attended births in the United States, 1990-2012: results from revised birth certificate data.

Science.gov (United States)

Declercq, Eugene

2015-01-01

Data on attendance at birth by midwives in the United States have been available on the national level since 1989, allowing for the documentation of long-term trends. New items on payer source and prepregnancy body mass index (BMI) from a 2003 revision of the birth certificate provide an opportunity to examine additional aspects of US midwifery practice. The data in this report are based on records on birth attendant gathered as part of the US National Standard Certificate of Live Birth from a public use Web site, Vital Stats (http://www.cdc.gov/nchs/VitalStats.htm), which allows users to create and download specialized tables. Analysis of new items on prepregnancy BMI and birth payer source are limited to the 38 states (86% of US births) that adopted the revised birth certificate by 2012. Between 1989 and 2012, the proportion of all births attended by certified nurse-midwives (CNMs) increased from 3.3% to 7.9%. The proportion of vaginal births attended by CNMs reached an all-time high of 11.9%. Births attended by "other midwives" (typically certified professional midwives) rose to a peak of 28,343, or 0.7% of all US births. The distribution of payer source for CNM-attended births (44% Medicaid; 44% private insurance; 6% self-pay) is very similar to the national distribution, whereas the majority (53%) of births attended by other midwives are self-pay. Women whose births are attended by other midwives are less likely (13%) to have a prepregnancy BMI in the obese range than women attended by CNMs (19%) or overall (24%). The total number of births attended by CNMs and other midwives has remained steady or grown at a time when total US births have declined, resulting in the largest proportions of midwife-attended births in the quarter century that such data have been collected. © 2015 by the American College of Nurse-Midwives.

MRI of rotator cuff muscle atrophy in relation to glenohumeral joint incongruence in brachial plexus birth injury

International Nuclear Information System (INIS)

Poeyhiae, Tiina H.; Nietosvaara, Yrjaenae A.; Peltonen, Jari I.; Remes, Ville M.; Kirjavainen, Mikko O.; Lamminen, Antti E.

2005-01-01

Purpose: To evaluate rotator cuff muscles and the glenohumeral (GH) joint in brachial plexus birth injury (BPBI) using MRI and to determine whether any correlation exists between muscular abnormality and the development of glenoid dysplasia and GH joint incongruity. Thirty-nine consecutive BPBI patients with internal rotation contracture or absent active external rotation of the shoulder joint were examined clinically and imaged with MRI. In the physical examination, passive external rotation was measured to evaluate internal rotation contracture. Both shoulders were imaged and the glenoscapular angle, percentage of humeral head anterior to the middle of the glenoid fossa (PHHA) and the greatest thickness of the subscapular, infraspinous and supraspinous muscles were measured. The muscle ratio between the affected side and the normal side was calculated to exclude age variation in the assessment of muscle atrophy. All muscles of the rotator cuff were atrophic, with the subscapular and infraspinous muscles being most severely affected. A correlation was found between the percentage of humeral head anterior to the middle of the glenoid fossa (PHHA) and the extent of subscapular muscle atrophy (r s =0.45, P=0.01), as well as between its ratio (r s =0.5, P P=0.01). Severity of rotator cuff muscle atrophy correlated with increased glenoid retroversion and the degree of internal rotation contracture. Glenoid retroversion and subluxation of the humeral head are common in patients with BPBI. All rotator cuff muscles are atrophic, especially the subscapular muscle. Muscle atrophy due to neurogenic damage apparently results in an imbalance of the shoulder muscles and progressive retroversion and subluxation of the GH joint, which in turn lead to internal rotation contracture and deformation of the joint.

CHANGES IN SEX RATIO AT BIRTH IN CHINA: A DECOMPOSITION BY BIRTH ORDER.

Science.gov (United States)

Jiang, Quanbao; Yu, Qun; Yang, Shucai; Sánchez-Barricarte, Jesús J

2017-11-01

The long-term high sex ratio at birth (SRB) is a serious issue in China. In this study, changes in SRB were decomposed into variations in SRB by birth order and compositional changes in female births by birth order. With SRB data from China's surveys and censuses, and SRB data from South Korea's vital registration and censuses from 1980-2015, the trend and decomposition results in SRB were compared between China and South Korea, and the decomposition results for urban and rural SRBs, and for provinces, are presented. In both China and South Korea the rise in the SRB was driven by a rise in the SRB at all birth orders, which was only partly counteracted by the change in the distribution of births by order. The overall rise in the SRB ended when there was a decline in the SRB at second birth or above in South Korea. In China the total effect of variations in SRB of all birth orders increased more for the rural population than for the urban population before 2000, resulting in a higher total SRB for rural than urban population. After 2000, the total effect of variations in SRB of all birth orders lowered the total SRB for the rural population, whereas the effect of compositional change increased the total SRB, leading to a very slight rise in the total SRB for the rural population. At the province level, there was no spatial autocorrelation for the changes in total SRB by province, the total effect of variations in SRB of all birth orders or the effect of compositional change. The effect of variations in SRB by birth order accounted for the majority of changes in total SRB in most provinces.

midwifery homes (similar to birth centres) are rich in midwifery wisdom and skills that differ from those in hospital obstetrical departments, and a certain percentage of pregnant women prefer birth in these settings. This study aimed to understand the organisation of the perinatal environment considered important by independent midwives in non-hospital settings and to clarify the processes involved. semi-structured qualitative interview study and constant comparative analysis. 14 independent midwives assisting at births in midwifery homes in Japan, and six independent midwives assisting at home births. Osaka, Kyoto, Nara, and Shiga, Japan. midwives assisting at non-hospital births organised the birth environment based on the following four categories: 'an environment where the mother and family are autonomous'; 'a physical environment that facilitates birth'; 'an environment that facilitates the movement of the mother for birth'; and 'scrupulous safety preparation'. These, along with their sub-categories, are presented in this paper. independent midwives considered it important to create a candid relationship between the midwife and the woman/family from the period of pregnancy to facilitate birth in which the woman and her family were autonomous. They also organised a distinctive environment for non-hospital birth, with preparations to guarantee safety. Experiential knowledge and skills played a major part in creating an environment to facilitate birth, and the effectiveness of this needs to be investigated objectively in future research.

Socioeconomic inequality in preterm birth in four Brazilian birth cohort studies

Directory of Open Access Journals (Sweden)

Ana Daniela Izoton de Sadovsky

Full Text Available Abstract Objective: To analyze economic inequality (absolute and relative due to family income in relation to the occurrence of preterm births in Southern Brazil. Methods: Four birth cohort studies were conducted in the years 1982, 1993, 2004, and 2011. The main exposure was monthly family income and the primary outcome was preterm birth. The inequalities were calculated using the slope index of inequality and the relative index of inequality, adjusted for maternal skin color, education, age, and marital status. Results: The prevalence of preterm births increased from 5.8% to approximately 14% (p-trend < 0.001. Late preterm births comprised the highest proportion among the preterm births in all studies, although their rates decreased over the years. The analysis on the slope index of inequality demonstrated that income inequality arose in the 1993, 2004, and 2011 studies. After adjustment, only the 2004 study maintained the difference between the poorest and the richest subjects, which was 6.3 percentage points. The relative index of inequality showed that, in all studies, the poorest mothers were more likely to have preterm newborns than the richest. After adjustment for confounding factors, it was observed that the poorest mothers only had a greater chance of this outcome in 2004. Conclusion: In a final model, economic inequalities resulting from income were found in relation to preterm births only in 2004, although a higher prevalence of prematurity continued to be observed in the poorest population, in all the studies.

Intake of colostrum after birth is essential to stimulate intestinal growth and function, and to provide systemic immunological protection via absorption of Immunoglobulin G (IgG). The birth order and weight of 745 piglets (from 75 litters) were recorded during a one-week period of farrowing. Only pigs weighing greater than 0.68 kg birth weight were chosen for the trial. Sow colostrum was collected during parturition, and piglets were bled between 48 and 72 hours post-birth. Piglet serum IgG and colostral IgG concentrations were determined by radial immunodiffusion. Sow parity had a significant (P birth order accounted for another 4% of the variation observed in piglet serum IgG concentration (P birth weight had no detectable effect. Piglet serum IgG concentration had both a linear (P Birth order had no detectable effect on survival, but birth weight had a positive linear effect (P birth had a 68% survival rate, and those weighing 1.6 kg (n = 158) had an 89% survival. We found that the combination of sow colostrum IgG concentration and birth order can account for 10% of the variation of piglet serum IgG concentration and that piglets with less than 1,000 mg/dl IgG serum concentration and weight of 0.9 kg at birth had low survival rate when compared to their larger siblings. The effective management of colostrum uptake in neonatal piglets in the first 24 hrs post-birth may potentially improve survival from birth to weaning.

During the last decade, a rapid increase of birth locations for low-risk births, other than conventional obstetric units, has been seen in the Netherlands. Internationally some of such locations are called birth centres. The varying international definitions for birth centres are not directly applicable for use within the Dutch obstetric system. A standard definition for a birth centre in the Netherlands is lacking. This study aimed to develop a definition of birth centres for use in the Netherlands, to identify these centres and to describe their characteristics. International definitions of birth centres were analysed to find common descriptions. In July 2013 the Dutch Birth Centre Questionnaire was sent to 46 selected Dutch birth locations that might qualify as birth centre. Questions included: location, reason for establishment, women served, philosophies, facilities that support physiological birth, hotel-facilities, management, environment and transfer procedures in case of referral. Birth centres were visited to confirm the findings from the Dutch Birth Centre Questionnaire and to measure distance and time in case of referral to obstetric care. From all 46 birth locations the questionnaires were received. Based on this information a Dutch definition of a birth centre was constructed. This definition reads: "Birth centres are midwifery-managed locations that offer care to low risk women during labour and birth. They have a homelike environment and provide facilities to support physiological birth. Community midwives take primary professional responsibility for care. In case of referral the obstetric caregiver takes over the professional responsibility of care." Of the 46 selected birth locations 23 fulfilled this definition. Three types of birth centres were distinguished based on their location in relation to the nearest obstetric unit: freestanding (n = 3), alongside (n = 14) and on-site (n = 6). Transfer in case of referral was necessary for all

The novice birthing: theorising first-time mothers' experiences of birth at home and in hospital in Australia.

to explore first-time mothers' experiences of birth at home and in hospital in Australia. a grounded theory methodology was used. Data were generated from in-depth interviews with women in their own homes. Sydney, Australia. 19 women were interviewed. Seven women who gave in a public hospital and seven women who gave birth for the first time at home were interviewed and their experiences were contrasted with two mothers who gave birth for the first time in a birth centre, one mother who gave birth for the first time in a private hospital and two women who had given birth more than once. three categories emerged from the analysis: preparing for birth, the novice birthing and processing the birth. These women shared a common core experience of seeing that they gave birth as 'novices'. The basic social process running through their experience of birth, regardless of birth setting, was that, as novices, they were all 'reacting to the unknown'. The mediating factors that influenced the birth experiences of these first-time mothers were preparation, choice and control, information and communication, and support. The quality of midwifery care both facilitated and hindered these needs, contributing to the women's perceptions of being 'honoured'. The women who gave birth at home seemed to have more positive birth experiences. identifying the novice status of first-time mothers and understanding the way in which they experience birth better explains previous research that reports unrealistic expectations and fear that may be associated with first-time birthing. It demonstrates how midwives can contribute to positive birth experiences by being aware that first-time mothers, irrespective of birth setting, are essentially reacting to the unknown as they negotiate the experience of birth.

to examine the relationship between attitudes towards home birth and birth outcomes, and whether women's attitudes towards birth and intervention affected this relationship. a prospective cohort study. the study was set in Iceland, a sparsely populated island with harsh terrain, 325,000 inhabitants, high fertility and home birth rates, and less than 5000 births a year. a convenience sample of women who attended antenatal care in Icelandic health care centres, participated in the Childbirth and Health Study in 2009-2011, and expressed consistent attitudes towards home birth (n=809). of the participants, 164 (20.3%) expressed positive attitudes towards choosing home birth and 645 (79.7%) expressed negative attitudes. Women who had a positive attitude towards home birth had significantly more positive attitudes towards birth and more negative attitudes towards intervention than did women who had a negative attitude towards home birth. Of the 340 self-reported low-risk women that answered questionnaires on birth outcomes, 78 (22.9%) had a positive attitude towards home birth and 262 (77.1%) had a negative attitude. Oxytocin augmentation (19.2% (n=15) versus 39.1% (n=100)), epidural analgesia (19.2% (n=15) versus 33.6% (n=88)), and neonatal intensive care unit admission rates (0.0% (n=0) versus 5.0% (n=13)) were significantly lower among women who had a positive attitude towards home birth. Women's attitudes towards birth and intervention affected the relationship between attitudes towards home birth and oxytocin augmentation or epidural analgesia. the beneficial effect of planned home birth on maternal outcome in Iceland may depend to some extent on women's attitudes towards birth and intervention. Efforts to de-stigmatise out-of-hospital birth and de-medicalize women's attitudes towards birth might increase women׳s use of health-appropriate birth services. Copyright © 2016 Elsevier Ltd.

Approximately 1% of American women give birth at home and face substantial obstacles when they make this choice. This study describes the reasons that women in the United States choose home birth. A qualitative descriptive secondary analysis was conducted in a previously collected dataset obtained via an online survey. The sample consisted of 160 women who were US residents and planned a home birth at least once. Content analysis was used to study the responses from women to one essay question: "Why did you choose home birth?" Women who participated in the study were mostly married (91%) and white (87%). The majority (62%) had a college education. Our analysis revealed 508 separate statements about why these women chose home birth. Responses were coded and categorized into 26 common themes. The most common reasons given for wanting to birth at home were: 1) safety (n = 38); 2) avoidance of unnecessary medical interventions common in hospital births (n = 38); 3) previous negative hospital experience (n = 37); 4) more control (n = 35); and 5) comfortable, familiar environment (n = 30). Another dominant theme was women's trust in the birth process (n = 25). Women equated medical intervention with reduced safety and trusted their bodies' inherent ability to give birth without interference.

Extensive neuromotor development occurs early in human life, but the time that a brain injury occurs during development has not been rigorously studied when quantifying motor impairments. This study investigated the impact of timing of brain injury on the magnitude and distribution of weakness in the paretic arm of individuals with childhood-onset hemiparesis. A total of 24 individuals with hemiparesis were divided into time periods of injury before birth (PRE-natal, n = 8), around the time of birth (PERI-natal, n = 8), or after 6 months of age (POST-natal, n = 8). They, along with 8 typically developing peers, participated in maximal isometric shoulder, elbow, wrist, and finger torque generation tasks using a multiple-degree-of-freedom load cell to quantify torques in 10 directions. A mixed-model ANOVA was used to determine the effect of group and task on a calculated relative weakness ratio between arms. There was a significant effect of both time of injury group (P < .001) and joint torque direction (P < .001) on the relative weakness of the paretic arm. Distal joints were more affected compared with proximal joints, especially in the POST-natal group. The distribution of weakness provides evidence for the relative preservation of ipsilateral corticospinal motor pathways to the paretic limb in those individuals injured earlier, whereas those who sustained later injury may rely more on indirect ipsilateral corticobulbospinal projections during the generation of torques with the paretic arm.

Previous research has established that birth order affects outcomes such as educational achievements, IQ and earnings. The mechanisms behind these effects are, however, still largely unknown. In this paper, we examine birth-order effects on health, and whether health at young age could be a transmission channel for birth-order effects observed later in life. We find no support for the birth-order effect having a biological origin; rather firstborns have worse health at birth. This disadvantag...

Studies of planned home births attended by registered midwives have been limited by incomplete data, nonrepresentative sampling, inadequate statistical power and the inability to exclude unplanned home births. We compared the outcomes of planned home births attended by midwives with those of planned hospital births attended by midwives or physicians. We included all planned home births attended by registered midwives from Jan. 1, 2000, to Dec. 31, 2004, in British Columbia, Canada (n = 2889), and all planned hospital births meeting the eligibility requirements for home birth that were attended by the same cohort of midwives (n = 4752). We also included a matched sample of physician-attended planned hospital births (n = 5331). The primary outcome measure was perinatal mortality; secondary outcomes were obstetric interventions and adverse maternal and neonatal outcomes. The rate of perinatal death per 1000 births was 0.35 (95% confidence interval [CI] 0.00-1.03) in the group of planned home births; the rate in the group of planned hospital births was 0.57 (95% CI 0.00-1.43) among women attended by a midwife and 0.64 (95% CI 0.00-1.56) among those attended by a physician. Women in the planned home-birth group were significantly less likely than those who planned a midwife-attended hospital birth to have obstetric interventions (e.g., electronic fetal monitoring, relative risk [RR] 0.32, 95% CI 0.29-0.36; assisted vaginal delivery, RR 0.41, 95% 0.33-0.52) or adverse maternal outcomes (e.g., third- or fourth-degree perineal tear, RR 0.41, 95% CI 0.28-0.59; postpartum hemorrhage, RR 0.62, 95% CI 0.49-0.77). The findings were similar in the comparison with physician-assisted hospital births. Newborns in the home-birth group were less likely than those in the midwife-attended hospital-birth group to require resuscitation at birth (RR 0.23, 95% CI 0.14-0.37) or oxygen therapy beyond 24 hours (RR 0.37, 95% CI 0.24-0.59). The findings were similar in the comparison with

We sought to evaluate perinatal morbidity by delivery location (hospital, freestanding birth center, and home). Selected 2006 US birth certificate data were accessed online from the Centers for Disease Control and Prevention. Low-risk maternal and newborn outcomes were tabulated and compared by birth facility. A total of 745,690 deliveries were included, of which 733,143 (97.0%) occurred in hospital, 4661 (0.6%) at birth centers, and 7427 (0.9%) at home. Compared with hospital deliveries, home and birthing center deliveries were associated with more frequent prolonged and precipitous labors. Home births experienced more frequent 5-minute Apgar scores home and birthing center deliveries were associated with less frequent chorioamnionitis, fetal intolerance of labor, meconium staining, assisted ventilation, neonatal intensive care unit admission, and birthweight Home births are associated with a number of less frequent adverse perinatal outcomes at the expense of more frequent abnormal labors and low 5-minute Apgar scores.

Acute kidney injury (AKI) occurs commonly in preterm neonates and is associated with increased morbidity and mortality. To examine the association between caffeine citrate administration and AKI in preterm neonates in the first 7 days after birth and to test the hypothesis that caffeine administration would be associated with reduced incidence and severity of AKI. This study was a secondary analysis of the Assessment of Worldwide Acute Kidney Injury Epidemiology in Neonates (AWAKEN) study, a retrospective observational cohort that enrolled neonates born from January 1 to March 31, 2014. The dates of analysis were October 2016 to December 2017. The setting was an international, multicenter cohort study of neonates admitted to 24 participating level III or IV neonatal intensive care units. Participants met the original inclusion and exclusion criteria of the AWAKEN study. Additional exclusion criteria for this study included participants greater than or equal to 33 weeks' gestation at birth, admission after age 7 days, use of theophylline in the neonatal intensive care unit, or lack of data to define AKI. There were 675 preterm neonates available for analysis. Administration of caffeine in the first 7 days after birth. The primary outcome was the incidence of AKI (based on the modified neonatal Kidney Disease: Improving Global Outcomes [KDIGO] definition) in the first 7 days after birth. The hypothesis that caffeine administration would be associated with reduced AKI incidence was formulated before data analysis. The study cohort (n = 675) was 55.4% (n = 374) male, with a mean (SD) gestational age of 28.9 (2.8) weeks and a mean (SD) birth weight of 1285 (477) g. Acute kidney injury occurred in 122 neonates (18.1%) in the first 7 days after birth. Acute kidney injury occurred less frequently among neonates who received caffeine than among those who did not (50 of 447 [11.2%] vs 72 of 228 [31.6%], P < .01). After multivariable adjustment, administration of

Narcissism and birth order.

Eyring, W E; Sobelman, S

1996-04-01

The purpose of this investigation was to clarify the relationship between birth-order position and the development of narcissism, while refining research and theory. The relationship between birth-order status and narcissism was examined with a sample of 79 undergraduate students (55 women and 24 men). These subjects were placed in one of the four following birth-order categories of firstborn, second-born, last-born, and only children. These categories were chosen given their significance in Adlerian theory. Each subject completed the Narcissistic Personality Inventory and a demographic inventory. Based on psychodynamic theory, it was hypothesized that firstborn children were expected to score highest, but statistical significance was not found for an association between narcissism and birth order. Further research is urged to investigate personality theory as it relates to parenting style and birth order.

This report presents 2004 data on U.S. births according to a wide variety of characteristics. Data are presented for maternal demographic characteristics including age, live-birth order, race, Hispanic origin, marital status, and educational attainment; maternal lifestyle and health characteristics (medical risk factors, weight gain, and tobacco use); medical care utilization by pregnant women (prenatal care, obstetric procedures, characteristics of labor and/or delivery, attendant at birth, and method of delivery); and infant characteristics (period of gestation, birthweight, Apgar score, congenital anomalies, and multiple births). Also presented are birth and fertility rates by age, live-birth order, race, Hispanic origin, and marital status. Selected data by mother's state of residence are shown, as well as data on month and day of birth, sex ratio, and age of father. Trends in fertility patterns and maternal and infant characteristics are described and interpreted. Descriptive tabulations of data reported on the birth certificates of the 4.1 million births that occurred in 2004 are presented. Denominators for population-based rates are post-censal estimates derived from the U.S. 2000 census. In 2004, 4,112,052 births were registered in the United States, less than 1 percent more than the number in 2003. The crude birth rate declined slightly; the general fertility rate increased by less than 1 percent. Childbearing among teenagers and women aged 20-24 years declined to record lows. Rates for women aged 25-34 and 45-49 years were unchanged, whereas rates for women aged 35-44 years increased. All measures of unmarried childbearing rose in 2004. Smoking during pregnancy continued to decline. No improvement was seen in the timely initiation of prenatal care. The cesarean delivery rate jumped 6 percent to another all-time high, whereas the rate of vaginal birth after previous cesarean fell by 13 percent. Preterm and low birthweight rates continued their steady rise

Volpe, Katherine A; Snowden, Jonathan M; Cheng, Yvonne W; Caughey, Aaron B

2016-11-01

To examine birthweight and other predictors of brachial plexus injury (BPI) among births complicated by shoulder dystocia. A retrospective cohort study of term births complicated by shoulder dystocia in California between 1997 and 2006. Birthweight at time of delivery was stratified into 500-g intervals. Women were further stratified by diabetes status, parity, and race/ethnicity. The perinatal outcome of BPI was assessed. This study included 62,762 deliveries complicated by shoulder dystocia, of which 3168 (5 %) resulted in BPI. The association between birthweight and BPI remained significant regardless of confounders. Each increasing birthweight interval was associated with an increasing risk of BPI compared with 3000-3499-g birthweight. Race/ethnicity, diabetes, and parity were also independently associated with BPI. Increasing birthweight increases the risk of BPI among births with shoulder dystocia, independent of advanced maternal age, race, parity, gestational diabetes, or operative vaginal delivery.

Risk of death during the first year of life due to external causes, such as unintentional injury and homicide, may be higher among twins and higher-order multiples than among singletons in the United States. We used national birth cohort linked birth-infant death data (2000-2010) to evaluate the risk of infant mortality due to external causes in multiples versus singletons in the United States. Risk of death from external causes during the study period was 3.6 per 10,000 live births in singletons and 5.1 per 10,000 live births in multiples. Using log-binomial regression, the corresponding unadjusted risk ratio was 1.40 (95% confidence interval (CI): 1.30, 1.50). After adjustment for maternal age, marital status, race/ethnicity, and education, the risk ratio was 1.68 (95% CI: 1.56, 1.81). Infant deaths due to external causes were most likely to occur between 2 and 7 months of age. Applying inverse probability weighting and assuming a hypothetical intervention where no infants were low birth weight, the adjusted controlled direct effect of plurality on infant mortality due to external causes was 1.64 (95% CI: 1.39, 1.97). Twins and higher-order multiples were at greater risk of infant mortality due to external causes, particularly between 2 and 7 months of age, and this risk appeared to be mediated largely by factors other than low-birth-weight status.

More than 10% of all planned home births in high-income countries are completed in the hospital. The aim of this study was to compare the birth experiences among women who planned to give birth at home and completed the birth at home and women who were transferred to hospital during or immediately after the birth. All women in Sweden who had a planned home birth between 1998 and 2005 (n=671) were invited to participate in the study. The women who agreed to participate received one questionnaire for each planned home birth. Mixed methods were used for the analysis. Women who had been transferred during or immediately after the planned home birth had a more negative birth experience in general. In comparison with women who completed the birth at home, the odds ratio for being less satisfied was 13.5, CI 8.1-22.3. Reasons for being dissatisfied related to organizational factors, the way the women were treated or personal ability. Being transferred during a planned home birth negatively affects the birth experience. Treatments as well as organizational factors are considered to be obstacles for a positive birth experience when transfer is needed. Established links between the home birth setting and the hospital might enhance the opportunity for a positive birth experience irrespective of where the birth is completed.

Diffuse damage to the periventricular white matter has recently been suggested to be a cause of the cognitive deficits seen following preterm birth. It is unclear whether this form of injury can be visualised on MR imaging, but one group has described diffuse excessive high signal intensity (DEHSI) as a possible form of diffuse white matter injury. This finding is dependant on window imaging and the subjective assessment of the reviewer, but little data have been published on the degree of subjectivity on its appearance among raters. To assess the subjectivity of DEHSI on conventional and ultrafast T2-weighted MR imaging following preterm birth. An observational study of 40 preterm infants who had MR imaging of the brain around term-equivalent age, including conventional fast spin-echo (FSE) and ultrafast single-shot fast spin-echo (SSFSE) T2-weighted sequences in the axial plane. Images were anonymised and scored twice by four observers for the presence of DEHSI. Inter- and intra-observer agreement were calculated. Sixty-five percent of conventional and 100% of the ultrafast images were of diagnostic quality. DEHSI was noted in between 0% and 69.2% of conventional images and 27.5-90% of the ultrafast images. Inter- and intra-observer agreement ranged from none to moderate. The visual appearances of DEHSI on conventional FSE and ultrafast SSFSE T2-W images are highly subjective, limiting its clinical application. (orig.)

Wax, Joseph R; Lucas, F Lee; Lamont, Maryanne; Pinette, Michael G; Cartin, Angelina; Blackstone, Jacquelyn

2010-09-01

We sought to systematically review the medical literature on the maternal and newborn safety of planned home vs planned hospital birth. We included English-language peer-reviewed publications from developed Western nations reporting maternal and newborn outcomes by planned delivery location. Outcomes' summary odds ratios with 95% confidence intervals were calculated. Planned home births were associated with fewer maternal interventions including epidural analgesia, electronic fetal heart rate monitoring, episiotomy, and operative delivery. These women were less likely to experience lacerations, hemorrhage, and infections. Neonatal outcomes of planned home births revealed less frequent prematurity, low birthweight, and assisted newborn ventilation. Although planned home and hospital births exhibited similar perinatal mortality rates, planned home births were associated with significantly elevated neonatal mortality rates. Less medical intervention during planned home birth is associated with a tripling of the neonatal mortality rate. Copyright 2010 Mosby, Inc. All rights reserved.

The rate of twin pregnancies in the United States has stabilized at 32 per 1000 births in 2006. Aside from determining chorionicity, first-trimester screening and second-trimester ultrasound scanning should ascertain whether there are structural or chromosomal abnormalities. Compared with singleton births, genetic amniocentesis-related loss at births is higher (0.9% vs 2.9%, respectively). Selective termination for an anomalous fetus is an option, although the pregnancy loss rate is 7% at experienced centers. For singleton and twin births for African American and white women, approximately 50% of preterm births are indicated; approximately one-third of these births are spontaneous, and 10% of the births occur after preterm premature rupture of membranes. From 1989-2000, the rate of preterm twin births increased, for African American and white women alike, although the perinatal mortality rate has actually decreased. As with singleton births, tocolytics should be used judiciously and only for a limited time (births. Administration of antenatal corticosteroids is an evidence-based recommendation.

Stoll, Kathrin; Hall, Wendy

2013-01-01

In our secondary analysis of a cross-sectional survey, we explored predictors of childbirth fear for young women (n = 2,676). Young women whose attitudes toward pregnancy and birth were shaped by the media were 1.5 times more likely to report childbirth fear. Three factors that were associated with reduced fear of birth were women's confidence in reproductive knowledge, witnessing a birth, and learning about pregnancy and birth through friends. Offering age-appropriate birth education during primary and secondary education, as an alternative to mass-mediated information about birth, can be evaluated as an approach to reduce young women's childbirth fear.

This report presents preliminary data for 2000 on births in the United States. U.S. data on births are shown by age, race, and Hispanic origin of mother. Data on marital status, prenatal care, cesarean delivery, and low birthweight are also presented. Data in this report are based on more than 96 percent of births for 2000. The records are weighted to independent control counts of births received in State vital statistics offices in 2000. Comparisons are made with 1999 final data. The number of births rose 3 percent between 1999 and 2000. The crude birth rate increased to 14.8 per 1,000 population in 2000, 2 percent higher than the 1999 rate. The fertility rate rose 3 percent to 67.6 per 1,000 women aged 15-44 years between 1999 and 2000. The birth rate for teenagers, which has been falling since 1991, declined 2 percent in 2000 to 48.7 births per 1,000 females aged 15-19 years, another historic low. The rate for teenagers 15-17 years fell 4 percent, and the rate for 18-19 year olds was down 1 percent. Since 1991, rates have fallen 29 percent for teenagers 15-17 years and 16 percent for teenagers 18-19 years. Birth rates for all of the older age groups increased for 1999-2000: 1 percent among women aged 20-24 years, 3 percent for women aged 25-29 years, and 5 percent for women in their thirties. Rates for women aged 40-54 years were also up for 2000. The birth rate for unmarried women increased 2 percent to 45.2 births per 1,000 unmarried women aged 15-44 years in 2000, but was still lower than the peak reached in 1994. The number of births to unmarried women was up 3 percent, the highest number ever reported in the United States. However, the number of births to unmarried teenagers declined. The proportion of women who began prenatal care in the first trimester of pregnancy (83.2 percent) did not improve for 2000, nor did the rate of low birthweight (7.6 percent). The total cesarean rate rose for the fourth consecutive year to 22.9 percent, the result of both a

The birth order puzzle.

Zajonc, R B; Markus, H; Markus, G B

Studies relating intellectual performance to birth order report conflicting results, some finding intellectual scores to increase, others to decrease with birth order. In contrast, the relationship between intellectual performance and family size is stable and consistently replicable. Why do these two highly related variables generate such divergent results? This birth order puzzle is resolved by means of the confluence model that quantifies the influences upon intellectual growth arising within the family context. At the time of a new birth, two opposing influences act upon intellectual growth of the elder sibling: (a) his or her intellectual environment is "diluted" and (b) he or she loses the "last-born's handicap" and begins serving as an intellectual resource to the younger sibling. Since these opposite effects are not equal in magnitude, the differences in intellectual performance among birth ranks are shown to be age dependent. While elder children may surpass their younger siblings in intellectual performance at some ages, they may be overtaken by them at others. Thus when age is taken into consideration, the birth order literature loses its chaotic character and an orderly pattern of results emerges.

The Chernobyl accident, the male to female ratio at birth and birth rates.

Grech, Victor

2014-01-01

The male:female ratio at birth (male births divided by total live births - M/T) has been shown to increase in response to ionizing radiation due to gender-biased fetal loss, with excess female loss. M/T rose sharply in 1987 in central-eastern European countries following the Chernobyl accident in 1986. This study analyses M/T and births for the former Soviet Republics and for the countries most contaminated by the event. Annual birth data was obtained from the World Health Organisation. The countries with the highest exposure levels (by ¹³⁷Cs) were identified from an official publication of the International Atomic Energy Agency. All of the former Soviet states were also analysed and the periods before and after 1986 were compared. Except for the Baltic States, all regions in the former USSR showed a significant rise in M/T from 1986. There were significant rises in M/T in the three most exposed (Belarus, Ukraine and the Russian Federation). The birth deficit in the post-Soviet states for the ten years following Chernobyl was estimated at 2,072,666, of which 1,087,924 are accounted by Belarus and Ukraine alone. Chernobyl has resulted in the loss of millions of births, a process that has involved female even more than male fetuses. This is another and oft neglected consequence of widespread population radiation contamination.

Influence of birth order, birth weight, colostrum and serum immunoglobulin G on neonatal piglet survival

Full Text Available Abstract Background Intake of colostrum after birth is essential to stimulate intestinal growth and function, and to provide systemic immunological protection via absorption of Immunoglobulin G (IgG. The birth order and weight of 745 piglets (from 75 litters were recorded during a one-week period of farrowing. Only pigs weighing greater than 0.68 kg birth weight were chosen for the trial. Sow colostrum was collected during parturition, and piglets were bled between 48 and 72 hours post-birth. Piglet serum IgG and colostral IgG concentrations were determined by radial immunodiffusion. Results Sow parity had a significant (P Conclusion We found that the combination of sow colostrum IgG concentration and birth order can account for 10% of the variation of piglet serum IgG concentration and that piglets with less than 1,000 mg/dl IgG serum concentration and weight of 0.9 kg at birth had low survival rate when compared to their larger siblings. The effective management of colostrum uptake in neonatal piglets in the first 24 hrs post-birth may potentially improve survival from birth to weaning.

Full Text Available Audience: This scenario was developed to educate emergency medicine residents on the management of a precipitous birth in the emergency department (ED. The case is also appropriate for teaching of medical students and advanced practice providers, as well as reviewing the principles of crisis resource management, teamwork, and communication. Introduction: Patients with precipitous birth require providers to manage two patients simultaneously with limited time and resources. Crisis resource management skills will be tested once baby is delivered, and the neonate will require assessment for potential neonatal resuscitation. Objectives: At the conclusion of the simulation session, learners will be able to manage women who have precipitous deliveries, as well as perform neonatal assessment and management. Method: This session was conducted using high-fidelity simulation, followed by a debriefing session and lecture on precipitous birth management and neonatal evaluation.

Extensive neuromotor development occurs early in human life, and the timing of brain injury may affect the resulting motor impairment. In Part I of this series, it was demonstrated that the distribution of weakness in the upper extremity depended on the timing of brain injury in individuals with childhood-onset hemiparesis. The goal of this study was to characterize how timing of brain injury affects joint torque synergies, or losses of independent joint control. Twenty-four individuals with hemiparesis were divided into 3 groups based on the timing of their injury: before birth (PRE-natal, n = 8), around the time of birth (PERI-natal, n = 8), and after 6 months of age (POST-natal, n = 8). Individuals with hemiparesis and 8 typically developing peers participated in maximal isometric shoulder, elbow, wrist, and finger torque generation tasks while their efforts were recorded by a multiple degree-of-freedom load cell. Motor output in 4 joints of the upper extremity was concurrently measured during 8 primary torque generation tasks to quantify joint torque synergies. There were a number of significant coupling patterns identified in individuals with hemiparesis that differed from the typically developing group. POST-natal differences were most noted in the coupling of shoulder abductors with elbow, wrist, and finger flexors, while the PRE-natal group demonstrated significant distal joint coupling with elbow flexion. The torque synergies measured provide indirect evidence for the use of bulbospinal pathways in the POST-natal group, while those with earlier injury may use relatively preserved ipsilateral corticospinal motor pathways.

Blix, Ellen; Øian, Pål; Kumle, Merethe

2008-11-06

About 150 planned home births take place in Norway annually. Professionals have different opinions on whether such births are safe or not. The aim of the present study was to perform a systematic literature review on maternal and neonatal outcomes after planned home births. A review was performed of literature retrieved from searches in MEDLINE, PubMed, Embase, Cinahl and The Cochrane Library and relevant references found in the articles. The searches were limited to studies published in 1985 and later. 10 studies with data from 30 204 women who had planned and were selected to home birth at the onset of labour were included. Three of the studies had control groups including women with planned hospital births. All included studies were assessed to be of medium quality. Between 9.9 and 23.1 % of women and infants were transferred to hospital during labour or after birth. There were few caesarean sections, other interventions or complications in the studies assessed; the total perinatal mortality rate was 2.9/1000 and the intrapartum mortality rate 0.8/1000. There is no sound basis for discouraging low-risk women from planning a home birth. Results from the included studies do not directly apply to Norwegian conditions. Outcomes and transfers after planned home births should be systematically registered.

Therefore, knowledge about the epidemiology of soccer injuries could allow sports-medicine professionals, such as physicians and physiotherapists, to direct their work in specific preventive programs. Thus, our aim was to conduct an epidemiological survey of injuries sustained by professional soccer players from the same team who participated in the Brazilian championship premier league in 2009. To this end, we evaluated retrospectively player medical records from the team, which included name, date of birth, position, date of injury, mechanism of injury, and type of injury. In the period of study, 95 injuries were recorded: 42 (44.2% were recorded during matches, and 53 (55.8% during the training period. Injuries occurred more frequently in midfielders and strikers. All injuries happened in the lower limb, most of the injuries were muscular, and most occurred as the result of collisions with other athletes. In summary, this study demonstrates that there is a need for greater safety awareness in the training environment. Keywords: injuries, epidemiology, soccer players

Neonatal encephalopathic cerebral injury in South India assessed by perinatal magnetic resonance biomarkers and early childhood neurodevelopmental outcome.

Directory of Open Access Journals (Sweden)

Peter J Lally

Full Text Available Although brain injury after neonatal encephalopathy has been characterised well in high-income countries, little is known about such injury in low- and middle-income countries. Such injury accounts for an estimated 1 million neonatal deaths per year. We used magnetic resonance (MR biomarkers to characterise perinatal brain injury, and examined early childhood outcomes in South India.We recruited consecutive term or near term infants with evidence of perinatal asphyxia and a Thompson encephalopathy score ≥6 within 6 h of birth, over 6 months. We performed conventional MR imaging, diffusion tensor MR imaging and thalamic proton MR spectroscopy within 3 weeks of birth. We computed group-wise differences in white matter fractional anisotropy (FA using tract based spatial statistics. We allocated Sarnat encephalopathy stage aged 3 days, and evaluated neurodevelopmental outcomes aged 3½ years using Bayley III.Of the 54 neonates recruited, Sarnat staging was mild in 30 (56%; moderate in 15 (28% and severe in 6 (11%, with no encephalopathy in 3 (6%. Six infants died. Of the 48 survivors, 44 had images available for analysis. In these infants, imaging indicated perinatal rather than established antenatal origins to injury. Abnormalities were frequently observed in white matter (n = 40, 91% and cortex (n = 31, 70% while only 12 (27% had abnormal basal ganglia/thalami. Reduced white matter FA was associated with Sarnat stage, deep grey nuclear injury, and MR spectroscopy N-acetylaspartate/choline, but not early Thompson scores. Outcome data were obtained in 44 infants (81% with 38 (79% survivors examined aged 3½ years; of these, 16 (42% had adverse neurodevelopmental outcomes.No infants had evidence for established brain lesions, suggesting potentially treatable perinatal origins. White matter injury was more common than deep brain nuclei injury. Our results support the need for rigorous evaluation of the efficacy of rescue hypothermic

Full Text Available Inconsistent findings from four observational studies suggest that the risk of acute kidney injury (AKI may increase with increasing statin dose or potency, but none of the studies took statin-related severe muscle injury, including rhabdomyolysis, into account. We undertook a nationwide nested case-control study in New Zealand to examine the risk of AKI without concurrent serious muscle injury according to simvastatin dose in two cohorts: people without a history of renal disease and people with non-dialysis dependent chronic kidney disease.A total of 334,710 people aged ≥ 18 years without a history of renal disease (cohort 1 and 5,437 with non-dialysis dependent chronic kidney disease (cohort 2 who initiated simvastatin therapy between 1 January 2006 and 31 December 2013 were identified using national pharmaceutical dispensing and hospital discharge data. Patients who developed AKI without concurrent serious muscle injury during follow-up (cases were ascertained using hospital discharge and mortality data (n = 931 from cohort 1, n = 160 from cohort 2. Up to 10 controls per case, matched by date of birth, sex, and cohort entry date were randomly selected from the relevant cohort using risk set sampling.Relative to current use of 20mg simvastatin daily, the adjusted odds ratios and 95% confidence intervals (95% CI in cohort 1 for current use of 40mg and 80mg were 0.9 (95% CI 0.7-1.2 and 1.3 (95% CI 0.7-2.3, respectively. The adjusted odds ratio for 40mg in cohort 2 was 1.1 (95% CI 0.7-1.9; the numbers taking 80mg were very small and the confidence interval was correspondingly wide.The findings of this study suggest that a relationship between statin dose and AKI may not exist independent of serious muscle injury.

Reasons Why Women Choose Home Birth

Full Text Available Maternal deaths in the Philippines remain high. These deaths are mostly due to the large proportion of home births, complications of pregnancy and delivery, and lack of access to facilities and competently trained staff. Utilizing a descriptive, one-shot survey design, the study aimed to determine the reasons why women in a municipality in Iloilo prefer home birth. The respondents were interviewed using a validated questionnaire. Descriptive statistics were used to analyze and interpret the findings. The study revealed that the proportion of home births progressively declined from 2012 to 2014. Birth being imminent or inevitable is the number one reason that supports home birth. Autonomy, safety, affordability, readily available birthing equipment and supplies, accessibility of birth attendant, remote access by going to the birthing center, lack of transportation, and bad weather conditions also led women to give birth at home. Women from the rural areas of the municipality utilized available resources in the community which prompted the predominance of home deliveries assisted by traditional birth attendants (TBAs and even midwives, who were readily available nearby. This study recommends continuous improvement in existing maternal health interventions and strategies through engagement of women in policy planning, improvement of health service delivery, infrastructural enhancement, better care practices and continuous health education.

Objective. To establish the percentile charts of birth weights for gestational age and sex within the Cameroonian population. Methods. A review of medical records of infants born between January 2007 and December 2011 at the maternities of two hospitals in Cameroon, Central Africa. Multiple pregnancies, births of HIV infected women, stillbirths, and births with major fetal malformations were excluded. The smooth curves of birth weight for gestational age and sex were created using the Gamlss package under R.3.0.1 software. Results. The birth weights of 12837 live birth singleton infants born to HIV negative women between 28 and 42 weeks of gestation were analyzed to construct the birth weight curves for gestational age and sex. The smoothed percentile curves of birth weights for gestational age and sex of Cameroonian infants have demonstrated an increasing slope until 40 weeks and then a plateau. There was a varied difference of distribution in birth weights for gestational age between Cameroonian, Botswanan, American, and French infants. Conclusion. We established the reference curves of birth weights for gestational age and sex for Cameroonians. The difference in birth weight curves noted between Cameroonian, Botswanan, American, and French infants suggests the importance of establishing the regional birth weight norms.

Objective: The search for quality, cost-effective health care programs in the United States is now a major focus in the era of health care reform. New programs need to be evaluated as alternatives are developed in the health care system. The BirthPlace program provides comprehensive perinatal services with certified nurse-midwives and obstetricians working together in an integrated collaborative practice serving a primarily low-income population. Low-risk women are delivered by nurse-midwives in a freestanding birth center (The BirthPlace), which is one component of a larger integrated health network. All others are delivered by team obstetricians at the affiliated tertiary hospital. Wellness, preventive measures, early intervention, and family involvement are emphasized. The San Diego Birth Center Study is a 4-year research project funded by the U.S. Federal Agency for Health Care Policy and Research (#R01-HS07161) to evaluate this program. The National Birth Center Study (NEJM, 1989; 321(26): 1801-11) described the advantages and safety of freestanding birth centers. However, a prospective cohort study with a concurrent comparison group of comparable risk had not been conducted on a collaborative practice-freestanding birth center model to address questions of safety, cost, and patient satisfaction.Methods: The specific aims of this study are to compare this collaborative practice model to the traditional model of perinatal health care (physician providers and hospital delivery). A prospective cohort study comparing these two health care models was conducted with a final expected sample size of approximately 2,000 birth center and 1,350 traditional care subjects. Women were recruited from both the birth center and traditional care programs (private physicians offices and hospital based clinics) at the beginning of prenatal care and followed through the end of the perinatal period. Prenatal, intrapartum, postpartum and infant morbidity and mortality are being

Fingolimod is a sphingosine-1-phosphate receptor modulator used for multiple sclerosis treatment and acts on cellular processes such as apoptosis, endothelial permeability, and inflammation. We hypothesized that fingolimod has a positive effect on alleviating preterm fetal brain injury. Sixteen pregnant rats were divided into four groups of four rats each. On gestational day 17, i.p. endotoxin was injected to induce fetal brain injury, followed by i.p. fingolimod (4 mg/kg maternal weight). Hysterotomy for preterm delivery was performed 6 h after fingolimod. The study groups included (i) vehicle controls (i.p. normal saline only); (ii) positive controls (endotoxin plus saline); (iii) saline plus fingolimod; and (iv) endotoxin plus fingolimod treatment. Brain tissues of the pups were dissected for evaluation of interleukin (IL)-6, caspase-3, and S100β on immunohistochemistry. Maternal fingolimod treatment attenuated endotoxin-related fetal brain injury and led to lower immunoreactions for IL-6, caspase-3, and S100β compared with endotoxin controls (P < 0.0001 for all comparisons). Antenatal maternal fingolimod therapy had fetal neuroprotective effects by alleviating preterm birth-related fetal brain injury with inhibitory effects on inflammation and apoptosis. © 2017 Japan Society of Obstetrics and Gynecology.

Premature birth is the world's leading cause of neonatal mortality with worldwide estimates indicating 11.1% of all live births were preterm in 2010. Preterm birth rates are increasing in most countries with continual differences in survival rates amongst rich and poor countries. Preterm birth is currently an important unresolved global issue with research efforts focusing on uterine quiescence and activation, the 'omics' approaches and implementation science in order to reduce the incidence and increase survival rates of preterm babies. The journal Reproductive Health has published a supplement entitled Born Too Soon which addresses factors in the preconception and pregnancy period which may increase the risk of preterm birth and also outlines potential interventions which may reduce preterm birth rates and improve survival of preterm babies by as much as 84% annually. This is critical in order to achieve the Millennium Development Goal (MDG 4) for child survival by 2015 and beyond.

Many studies have investigated the possible association between birth order and risk of childhood cancer, although the evidence to date has been inconsistent. Birth order has been used as a marker for various in utero or childhood exposures and is relatively straightforward to assess. Data were obtained on all children born in Denmark between 1973 and 2010, involving almost 2.5 million births and about 5,700 newly diagnosed childhood cancers before the age of 20 years. Data were analyzed using Poisson regression models. We failed to observe associations between birth order and risk of any childhood cancer subtype, including acute lymphoblastic leukemia; all rate ratios were close to one. Further analyses stratified by birth cohort (those born between 1973 and 1990, and those born between 1991 and 2010) also failed to show any associations. Considering stillbirths and/or controlling for birth weight and parental age in the analyses had no effect on the results. Analyses by years of birth (those born between 1973 and 1990, and those born between 1991 and 2010) did not show any changes in the overall pattern of no association. In this large cohort of all children born in Denmark over an almost 40-year period, we did not observe an association between birth order and the risk of childhood cancer.

Socioeconomic inequality in preterm birth in four Brazilian birth cohort studies.

To analyze economic inequality (absolute and relative) due to family income in relation to the occurrence of preterm births in Southern Brazil. Four birth cohort studies were conducted in the years 1982, 1993, 2004, and 2011. The main exposure was monthly family income and the primary outcome was preterm birth. The inequalities were calculated using the slope index of inequality and the relative index of inequality, adjusted for maternal skin color, education, age, and marital status. The prevalence of preterm births increased from 5.8% to approximately 14% (p-trendinequality demonstrated that income inequality arose in the 1993, 2004, and 2011 studies. After adjustment, only the 2004 study maintained the difference between the poorest and the richest subjects, which was 6.3 percentage points. The relative index of inequality showed that, in all studies, the poorest mothers were more likely to have preterm newborns than the richest. After adjustment for confounding factors, it was observed that the poorest mothers only had a greater chance of this outcome in 2004. In a final model, economic inequalities resulting from income were found in relation to preterm births only in 2004, although a higher prevalence of prematurity continued to be observed in the poorest population, in all the studies.

Ethics and "normal birth".

Science.gov (United States)

Lyerly, Anne Drapkin

2012-12-01

The concept of "normal birth" has been promoted as ideal by several international organizations, although debate about its meaning is ongoing. In this article, I examine the concept of normalcy to explore its ethical implications and raise a trio of concerns. First, in its emphasis on nonuse of technology as a goal, the concept of normalcy may marginalize women for whom medical intervention is necessary or beneficial. Second, in its emphasis on birth as a socially meaningful event, the mantra of normalcy may unintentionally avert attention to meaning in medically complicated births. Third, the emphasis on birth as a normal and healthy event may be a contributor to the long-standing tolerance for the dearth of evidence guiding the treatment of illness during pregnancy and the failure to responsibly and productively engage pregnant women in health research. Given these concerns, it is worth debating not just what "normal birth" means, but whether the term as an ideal earns its keep. © 2012, Copyright the Authors Journal compilation © 2012, Wiley Periodicals, Inc.

To evaluate the effect of local endometrial injury (LEI) on clinical outcomes in ovum donation recipients. Retrospective cohort analysis of ovum donation cycles conducted from 2005 to 2012. Two private IVF centers. Total 737 ovum donation cycles. LEI by endometrial "scratch" with the use of a Pipelle catheter. Clinical pregnancy and live birth rates. No statistically significant differences were found in clinical pregnancy rates and live birth rates in cycles subjected to LEI compared with those without. Combination of LEI with fibroid uterus resulted with significantly higher clinical pregnancy rates compared with LEI in normal uterine anatomy. This is the first study done in ovum recipients who underwent LEI by a "scratch" procedure after failed implantation. Unlike most previous reports, which found improved pregnancy rates with the use of "scratch effect" or "minor endometrial injury" after repeated implantation failures in standard IVF with own eggs, we did not find any changes in implantation rates in a population of egg recipients following this procedure. In view of a possible positive effect of LEI in cycles with a previous four or more failures, prospective randomized controlled studies are warranted to better define the target population who may benefit from this intervention.

Functional neuroanatomy of executive function after neonatal brain injury in adults who were born very preterm.

Directory of Open Access Journals (Sweden)

Anastasia K Kalpakidou

Full Text Available Individuals who were born very preterm (VPT; <33 gestational weeks are at risk of experiencing deficits in tasks involving executive function in childhood and beyond. In addition, the type and severity of neonatal brain injury associated with very preterm birth may exert differential effects on executive functioning by altering its neuroanatomical substrates. Here we addressed this question by investigating with functional magnetic resonance imaging (fMRI the haemodynamic response during executive-type processing using a phonological verbal fluency and a working memory task in VPT-born young adults who had experienced differing degrees of neonatal brain injury. 12 VPT individuals with a history of periventricular haemorrhage and ventricular dilatation (PVH+VD, 17 VPT individuals with a history of uncomplicated periventricular haemorrhage (UPVH, 13 VPT individuals with no history of neonatal brain injury and 17 controls received an MRI scan whilst completing a verbal fluency task with two cognitive loads ('easy' and 'hard' letters. Two groups of VPT individuals (PVH+VD; n = 10, UPVH; n = 8 performed an n-back task with three cognitive loads (1-, 2-, 3-back. Results demonstrated that VPT individuals displayed hyperactivation in frontal, temporal, and parietal cortices and in caudate nucleus, insula and thalamus compared to controls, as demands of the verbal fluency task increased, regardless of type of neonatal brain injury. On the other hand, during the n-back task and as working memory load increased, the PVH+VD group showed less engagement of the frontal cortex than the UPVH group. In conclusion, this study suggests that the functional neuroanatomy of different executive-type processes is altered following VPT birth and that neural activation associated with specific aspects of executive function (i.e., working memory may be particularly sensitive to the extent of neonatal brain injury.

Effects of Maternal Age and Age-Specific Preterm Birth Rates on Overall Preterm Birth Rates - United States, 2007 and 2014.

Reductions in births to teens and preterm birth rates are two recent public health successes in the United States (1,2). From 2007 to 2014, the birth rate for females aged 15-19 years declined 42%, from 41.5 to 24.2 per 1,000 females. The preterm birth rate decreased 8.4%, from 10.41% to 9.54% of live births (1). Rates of preterm births vary by maternal age, being higher among the youngest and oldest mothers. It is unknown how changes in the maternal age distribution in the United States have affected preterm birth rates. CDC used birth data to assess the relative contributions of changes in the maternal age distribution and in age-specific preterm birth rates to the overall decrease in preterm birth rates. The preterm birth rate declined in all age groups. The effects of age distribution changes on the preterm birth rate decrease were different in younger and older mothers. The decrease in the proportion of births to mothers aged ≤19 and 20-24 years and reductions in age-specific preterm rates in all age groups contributed to the overall decline in the preterm birth rate. The increase in births to mothers aged ≥30 years had no effect on the overall preterm birth rate decrease. The decline in preterm births from 2007 to 2014 is related, in part, to teen pregnancy prevention and the changing maternal age distribution. Effective public health strategies for further reducing preterm birth rates need to be tailored to different age groups.

To investigate the extent of socioeconomic inequalities in the incidence of very preterm birth over the past decade. Ecological study of all 549 618 births in the former Trent health region, UK, from 1 January 1994 to 31 December 2003. All singleton births of 22(+0) to 32(+6) weeks gestation (7 185 births) were identified from population surveys of neonatal services and stillbirths. Poisson regression was used to calculate incidence of very preterm birth (22-32 weeks) and extremely preterm birth (22-28 weeks) by year of birth and decile of deprivation (child poverty section of the Index of Multiple Deprivation). Incidence of very preterm singleton birth rose from 11.9 per 1000 births in 1994 to 13.7 per 1000 births in 2003. Those from the most deprived decile were at nearly twice the risk of very preterm birth compared with those from the least deprived decile, with 16.4 per 1000 births in the most deprived decile compared with 8.5 per 1000 births in the least deprived decile (incidence rate ratio 1.94; 95% CI (1.73 to 2.17)). This deprivation gap remained unchanged throughout the 10-year period. The magnitude of socio-economic inequalities was the same for extremely preterm births (22-28 weeks incidence rate ratio 1.94; 95% CI (1.62 to 2.32)). This large, unique dataset of very preterm births shows wide socio-economic inequalities that persist over time. These findings are likely to have consequences on the burden of long-term morbidity. Our research can assist future healthcare planning, the monitoring of socio-economic inequalities and the targeting of interventions in order to reduce this persistent deprivation gap.

CALF CIRCUMFERENCE AT BIRTH: A SCREENING METHOD FOR DETECTION OF LOW BIRTH WEIGHT

Directory of Open Access Journals (Sweden)

Sandip Kumar

2012-12-01

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

Social causes of low birth weight.

The manifest importance of reducing the incidence of low birth weight is most obvious for the first year of life: low birth weight is the single most important factor affecting infant morbidity and mortality. However, there is growing evidence that the adverse consequences of low birth weight continue throughout the life cycle. This review deals primarily with social causes of low birth weight.

Neonatal Mortality of Planned Home Birth in the United States in Relation to Professional Certification of Birth Attendants.

Full Text Available Over the last decade, planned home births in the United States (US have increased, and have been associated with increased neonatal mortality and other morbidities. In a previous study we reported that neonatal mortality is increased in planned home births but we did not perform an analysis for the presence of professional certification status.The objective of this study therefore was to undertake an analysis to determine whether the professional certification status of midwives or the home birth setting are more closely associated with the increased neonatal mortality of planned midwife-attended home births in the United States.This study is a secondary analysis of our prior study. The 2006-2009 period linked birth/infant deaths data set was analyzed to examine total neonatal deaths (deaths less than 28 days of life in term singleton births (37+ weeks and newborn weight ≥ 2,500 grams without documented congenital malformations by certification status of the midwife: certified nurse midwives (CNM, nurse midwives certified by the American Midwifery Certification Board, and "other" or uncertified midwives who are not certified by the American Midwifery Certification Board.Neonatal mortality rates in hospital births attended by certified midwives were significantly lower (3.2/10,000, RR 0.33 95% CI 0.21-0.53 than home births attended by certified midwives (NNM: 10.0/10,000; RR 1 and uncertified midwives (13.7/10,000; RR 1.41 [95% CI, 0.83-2.38].

Going public: do risk and choice explain differences in caesarean birth rates between public and private places of birth in Australia?

women who birth in private facilities in Australia are more likely to have a caesarean birth than women who birth in public facilities and these differences remain after accounting for sector differences in the demographic and health risk profiles of women. However, the extent to which women's preferences and/or freedom to choose their mode of birth further account for differences in the likelihood of caesarean birth between the sectors remains untested. women who birthed in Queensland, Australia during a two-week period in 2009 were mailed a self-report survey approximately 3 months after birth. Seven hundred and fifty-seven women provided cross-sectional retrospective data on where they birthed (public or private facility), mode of birth (vaginal or caesarean) and risk factors, along with their preferences and freedom to choose their mode of birth. A hierarchical logistic regression was conducted to determine the extent to which maternal risk and freedom to choose one's mode of birth explain sector differences in the likelihood of having a caesarean birth. while there was no sector difference in women's preference for mode of birth, women who birthed in private facilities had higher odds of feeling able to choose either a vaginal or caesarean birth, and feeling able to choose only a caesarean birth. Women had higher odds of having caesarean birth if they birthed in private facilities, even after accounting for significant risk factors such as age, body mass index, previous caesarean and use of assisted reproductive technology. However, there was no association between place of birth and odds of having a caesarean birth after also accounting for freedom to choose one's mode of birth. these findings call into question suggestions that the higher caesarean birth rate in the private sector in Australia is attributable to increased levels of obstetric risk among women birthing in the private sector or maternal preferences alone. Instead, the determinants of sector

Previous studies demonstrated a significant reduction in thymic medullary and epithelial volumes in irradiated canine fetuses. The present study was performed to determine if this prenatal radiation-induced damage persists and is accompanied by functional immune abnormalities after birth. Six pregnant beagle dogs received sham-irradiation or single abdominal exposures to 200R of 60Co radiation at 35 days gestation. The mean fetal dose was approximately 1.5 Gy. Half the dogs of each litter were sacrificed at birth; half were sacrificed at 24 weeks of age. Following sacrifice, thymus sections from each dog were examined morphometrically. The following in vitro and in vivo assays were performed at selected times; lymphocyte blastogenesis, hematology, bone marrow progenitor cell (CFU-GM) colony growth, humoral antibody response to sheep red blood cells, dinitrochloro-benzene skin sensitization, and gross and histopathology. When compared with age-matched controls, thymic medullary volumes in irradiated dogs were significantly reduced at birth; but, by 24 weeks of age, were similar to control values. At 12-16 weeks of age irradiated dogs showed a significant decrease in humoral antibody responses to inoculated sheep red blood cells. In vitro culture of bone marrow demonstrated a significant reduction of CFU-GM colony growth in irradiated dogs at 24 weeks of age. This was accompanied by a reduction in peripheral white blood cell counts in these dogs from 12-24 weeks of age. These data suggest that radiation injury to the fetal lymphohematopoietic system results in significant postnatal immunologic and hematopoietic defects

Current Controversies in Newer Therapies to Treat Birth Asphyxia

Full Text Available Despite major advances in monitoring technology and knowledge of fetal and neonatal pathophysiology, neonatal hypoxic-ischemic encephalopathy (HIE remains one of the main causes of severe adverse neurological outcome in children. Until recently, there were no therapies other than supportive measures. Over the past several years, mild hypothermia has been proven to be safe to treat HIE. Unfortunately, this neuroprotective strategy seems efficient in preventing brain injury in some asphyxiated newborns, but not in all of them. Thus, there is increasing interest to rapidly understand how to refine hypothermia therapy and add neuroprotective or neurorestorative strategies. Several promising newer treatments to treat birth asphyxia and prevent its devastating neurological consequences are currently being tested. In this paper, the physiopathology behind HIE, the currently available treatment, the potential alternatives, and the next steps before implementation of these other treatments are reviewed.

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

Full Text Available Background: Progesterone is important in maintaining pregnancy. Progesterone supplementation may reduce risk of preterm birth in certain populations of pregnant women. The objective of this review was to develop evidence-based clinical recommendation for progesterone treatment in the prevention of preterm birth.Methods: A search in the Medline database was performed using keywords: progesterone, pregnancy, preterm birth, preterm labour, preterm delivery, randomized trial, and randomized controlled trial. We only included studies of vaginal progesterone treatments for the prevention of preterm birth and excluded studies on 17-α-hydroksiprogesterone caproate.Results: We report findings from twelve randomized trials conducted since 2003. These trials differ regarding inclusion criteria, progesterone dose, vehicle used, and duration of treatment. Inclusion criteria were: short uterine cervix (two trials, history of previous preterm birth (two trials, signs and symptoms of preterm labour (three trials, twin pregnancies (three trials, and multiple risk factors (among these history of previous preterm birth was the most common (two trials. Six of these twelve trials showed a significant reduction in preterm birth in the progesterone groups.Conclusions: Based on current evidence we recommend treatment with 200 mg of micronized progesterone daily, administered vaginally, in pregnant women found to have a short cervix (≤ 25 mm at 19-24 weeks. The treatment should be continued until 37 weeks.

This study investigates maternal and perinatal outcomes for women with low-risk pregnancies laboring in free-standing birth centers compared with laboring in a hospital maternity unit in a large New Zealand health district. The study used observational data from 47 381 births to women with low-risk pregnancies in South Auckland maternity facilities 2003-2010. Adjusted odds ratios with 95% confidence intervals were calculated for instrumental delivery, cesarean section, blood transfusion, neonatal unit admission, and perinatal mortality. Labor in birth centers was associated with significantly lower rates of instrumental delivery, cesarean section and blood transfusion compared with labor in hospital. Neonatal unit admission rates were lower for infants of nulliparous women laboring in birth centers. Intrapartum and neonatal mortality rates for birth centers were low and were not significantly different from the hospital population. Transfers to hospital for labor and postnatal complications occurred in 39% of nulliparous and 9% of multiparous labors. Risk factors identified for transfer were nulliparity, advanced maternal age, and prolonged pregnancy ≥41 weeks' gestation. Labor in South Auckland free-standing birth centers was associated with significantly lower maternal intervention and complication rates than labor in the hospital maternity unit and was not associated with increased perinatal morbidity. © 2017 Wiley Periodicals, Inc.

Home births in the United States, 1990-2009.

After 14 years of decline, the percentage of home births rose by 29% from 2004 to 2009, to the point where it is at the highest level since data on this item began to be collected in 1989. The overall increase in home births was driven mostly by a 36% increase for non-Hispanic white women. About 1 out of every 90 births to non-Hispanic white women are now home births. The percentage of home births for non-Hispanic white women was three to five times higher than for any other racial or ethnic group. Home births have a lower risk profile than hospital births, with fewer births to teenagers or unmarried women, and with fewer preterm, low birthweight, and multiple births. The lower risk profile of home compared with hospital births suggests that home birth attendants are selecting low-risk women as candidates for home birth. The increase in the percentage of home births from 2004 to 2009 was widespread and involved selected states from every region of the country. The large variations in the percentage of home births by state may be influenced by differences among states in laws pertaining to births are more prevalent among non-Hispanic white women (7). midwifery practice or out-of-hospital birth (8,9), as well as by differences in the racial and ethnic composition of state populations, as home Studies have suggested that most home births are intentional or planned home births, whereas others are unintentional or unplanned, because of an emergency situation (i.e., precipitous labor, labor complications, or unable to get to the hospital in time) (3,6). Although not representative of all U.S. births (see "Data source and methods"), 87% of home births in a 26-state reporting area (comprising 50% of U.S. births) were planned in 2009. For non-Hispanic white women, 93% of home births were planned (10). Women may prefer a home birth over a hospital birth for a variety of reasons, including a desire for a low-intervention birth in a familiar environment surrounded by family

Previous studies have reported strong associations between birth order, maternal age, and suicide, but these results might have been confounded by socioeconomic and other factors. To control for such factors, we compared suicide risk between siblings and studied how maternal age at child birth and birth order influenced risk in a cohort study of 1,690,306 Norwegians born in 1967-1996 who were followed up until 2008. Using stratified Cox regression, we compared suicide risk within families with 2 or more children in which one died from suicide. Altogether, 3,005 suicides occurred over a mean follow-up period of 15 years; 2,458 of these suicides occurred among 6,741 siblings within families of 2 or more siblings. Among siblings, a higher position in the birth order was positively associated with risk; each increase in birth order was associated with a 46% (adjusted hazard ratio = 1.46, 95% confidence interval: 1.29, 1.66) higher risk of suicide. For each 10-year increase in maternal age at child birth, the offspring's suicide risk was reduced by 57% (adjusted hazard ratio = 0.43, 95% confidence interval: 0.30, 0.62). Our study suggests that confounding due to familial factors is not likely to explain the associations of birth order and maternal age at child birth with suicide risk.

In Australia the choice to birth at home is not well supported and only 0.4% of women give birth at home with a registered midwife. Recent changes to regulatory requirements for midwives have become more restrictive and there is no insurance product that covers private midwives for intrapartum care at home. Freebirth (planned birth at home with no registered health professional) with an unregulated birth worker who is not a registered midwife or doctor (e.g. Doula, ex-midwife, lay midwife etc.) appears to have increased in Australia. The aim of this study is to explore the reasons why women choose to give birth at home with an unregulated birth worker (UBW) from the perspective of women and UBWs. Nine participants (five women who had UBWs at their birth and four UBWs who had themselves used UBWs in the past for their births) were interviewed in-depth and the data analysed using thematic analysis. Four themes were found: 'A traumatising system', 'An inflexible system'; 'Getting the best of both worlds' and 'Treated with love and respect versus the mechanical arm on the car assembly line'. Women interviewed for this study either experienced or were exposed to mainstream care, which they found traumatising. They were not able to access their preferred birth choices, which caused them to perceive the system as inflexible. They interpreted this as having no choice when choice was important to them. The motivation then became to seek alternative options of care that would more appropriately meet their needs, and help avoid repeated trauma through mainstream care. Women who engaged UBWs viewed them as providing the best of both worlds - this was birthing at home with a knowledgeable person who was unconstrained by rules or regulations and who respected and supported the woman's philosophical view of birth. Women perceived UBWs as not only the best opportunity to achieve a natural birth but also as providing 'a safety net' in case access to emergency care was required.

Planned home birth: the professional responsibility response.

This article addresses the recrudescence of and new support for midwife-supervised planned home birth in the United States and the other developed countries in the context of professional responsibility. Advocates of planned home birth have emphasized patient safety, patient satisfaction, cost effectiveness, and respect for women's rights. We provide a critical evaluation of each of these claims and identify professionally appropriate responses of obstetricians and other concerned physicians to planned home birth. We start with patient safety and show that planned home birth has unnecessary, preventable, irremediable increased risk of harm for pregnant, fetal, and neonatal patients. We document that the persistently high rates of emergency transport undermines patient safety and satisfaction, the raison d'etre of planned home birth, and that a comprehensive analysis undermines claims about the cost-effectiveness of planned home birth. We then argue that obstetricians and other concerned physicians should understand, identify, and correct the root causes of the recrudescence of planned home birth; respond to expressions of interest in planned home birth by women with evidence-based recommendations against it; refuse to participate in planned home birth; but still provide excellent and compassionate emergency obstetric care to women transported from planned home birth. We explain why obstetricians should not participate in or refer to randomized clinical trials of planned home vs planned hospital birth. We call on obstetricians, other concerned physicians, midwives and other obstetric providers, and their professional associations not to support planned home birth when there are safe and compassionate hospital-based alternatives and to advocate for a safe home-birth-like experience in the hospital.

Background: The moment of birth is seen as a miracle, a journey and even a religious act. Research stress how giving birth might facilitate interference with previous conceptions of how to make meaning of life existentially. However, birth as an existential life transformative event, has been...... explored only briefly in empirical research. The aim of this study was two-fold: Firstly, to explore how first-time mothers experienced their first birth in relation to existential meaning-making. Secondly, to describe the relationship between considerations related to existential meaning-making and time...... of birth. Method: The study was based on a nationwide questionnaire, conducted among Danish first time mothers, who had given birth either preterm or full-term (n=517). The questionnaire consisted of 46 overall items. Eight core items were analysed in this study. Findings Preliminary findings show that new...

The relationship between social disparity and specific causes of infant mortality has rarely been studied. The present study analyzed infant mortality trends according to the causes of death and the inequalities in specific causes of infant mortality between different parental social classes. We analyzed 8,209,836 births from the Statistics Korea between 1995 and 2009. The trends of disparity for cause-specific infant mortality according to parental education and employment were examined using the Cox proportional hazard model for the birth-year intervals of 1995-1999, 2000-2004, and 2005-2009. Adjusted hazard ratios were calculated after adjusting for infants' gender, parents' age, maternal obstetrical history, gestational age, and birth weight. An increasing trend in social inequalities in all-cause infant mortality according to paternal education was evident. Social inequalities in infant mortality were greater for "Not classified symptoms, signs and findings" (International Classification of Diseases 10th revision [ICD-10]: R00-R99) and "Injury, poisoning and of external causes" (S00-T98), particularly for "Ill-defined and unspecified causes" (R990) and "Sudden infant death syndrome (SIDS)" (R950); and increased overtime for "Not classified symptoms, signs and findings" (R00-R99), "Injury, poisoning and of external causes" (S00-T98) and "Conditions in perinatal period" (P00-P96), particularly for "SIDS" (R950) and "Respiratory distress syndrome of newborns (RDS)" (P220). The specific causes of infant mortality, in particular the "Not classified causes" (R00-R99 coded deaths) should be investigated more thoroughly to reduce inequality in health. © 2017 The Korean Academy of Medical Sciences.

Ordinal position the child holds within the sibling ranking of a family is related to intellectual functioning, personality, behavior, and development of psychopathology. To study the association between birth order and development of psychopathology in patients attending psychiatry services in a teaching hospital. Hospital-based cross-sectional study. Retrospective file review of three groups of patients was carried out. Patient-related variables like age of onset, birth order, family type, and family history of mental illness were compared with psychiatry diagnosis (ICD-10) generated. SPSS 13; descriptive statistics and one-way analysis of variance (ANOVA) were used. Mean age of onset of mental illness among the adult general psychiatry patients (group I, n = 527) was found to be 33.01 ± 15.073, while it was 11.68 ± 4.764 among the child cases (group II, n = 47) and 26.74 ± 7.529 among substance abuse cases (group III, n = 110). Among group I patients, commonest diagnosis was depression followed by anxiety and somatoform disorders irrespective of birth order. Dissociative disorders were most prevalent in the first born child (36.7%) among group II patients. Among group III patients, alcohol dependence was maximum diagnosis in all birth orders. Depression and alcohol dependence was the commonest diagnosis in adult group irrespective of birth order.

Both gestation and birth weight have significant impact on mortality and morbidity in newborn infants. Nomograms at birth allow classification of infants into small for gestational age (SGA) and large for gestational age (LGA) categories, for risk stratification and more intensive monitoring. To date, the growth charts for preterm newborn infants in Singapore are based on the Fenton growth charts, which are constructed based on combining data from various Western growth cohorts. Hence, we aim to create Singapore nomograms for birth weight, length and head circumference at birth, which would reflect the norms and challenges faced by local infants. Growth parameters of all babies born or admitted to our unit from 2001 to 2012 were retrieved. Following exclusion of outliers, nomograms for 3 percentiles of 10th, 50th, and 90th were generated for the gestational age (GA) ranges of 25 to 42 weeks using quantile regression (QR) combined with the use of restricted cubic splines. Various polynomial models (second to third degrees) were investigated for suitability of fit. The optimum QR model was found to be a third degree polynomial with a single knotted cubic spline in the mid-point of the GA range, at 33.5 weeks. Check for goodness of fit was done by visual inspection first. Next, check was performed to ensure the correct proportion: 10% of all cases fall above the upper 90th percentile and 10% fall below the lower 10th percentile. Furthermore, an alternative formula-based method of nomogram construction, using mean, standard deviation (SD) and assumption of normality at each gestational age, was used for counterchecking. A total of 13,403 newborns were included in the analysis. The new infant-foetal growth charts with respect to birth weight, heel-crown length and occipitofrontal circumference from 25 to 42 weeks gestations with the 10th, 50th and 90th were presented. Nomograms for birth weight, length and head circumference at birth had significant impact on neonatal

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

Background There is a lack of data on the safety of midwife-led maternity care in remote or indigenous communities. In a de facto natural “experiment”, birth outcomes were assessed by primary birthing attendant in two sets of remote Inuit communities. Methods A geocoding-based retrospective birth cohort study in 14 Inuit communities of Nunavik, Canada, 1989–2000: primary birth attendants were Inuit midwives in the Hudson Bay (1529 Inuit births) vs western physicians in Ungava Bay communities (1197 Inuit births). The primary outcome was perinatal death. Secondary outcomes included stillbirth, neonatal death, post-neonatal death, preterm, small-for-gestational-age and low birthweight birth. Multilevel logistic regression was used to obtain the adjusted odds ratios (aOR) controlling for maternal age, marital status, parity, education, infant sex and plurality, community size and community-level random effects. Results The aORs (95% confidence interval) for perinatal death comparing the Hudson Bay vs Ungava Bay communities were 1.29 (0.63 to 2.64) for all Inuit births and 1.13 (0.48 to 2.47) for Inuit births at ≥28 weeks of gestation. There were no statistically significant differences in the crude or adjusted risks of any of the outcomes examined. Conclusion Risks of perinatal death were somewhat but not significantly higher in the Hudson Bay communities with midwife-led maternity care compared with the Ungava Bay communities with physician-led maternity care. These findings are inconclusive, although the results excluding extremely preterm births are more reassuring concerning the safety of midwife-led maternity care in remote indigenous communities.

Becoming a parent to a child with birth asphyxia—From a traumatic delivery to living with the experience at home

Full Text Available The aim of this study is to describe the experiences of becoming a parent to a child with birth asphyxia treated with hypothermia in the neonatal intensive care unit (NICU. In line with the medical advances, the survival of critically ill infants with increased risk of morbidity is increasing. Children who survive birth asphyxia are at a higher risk of functional impairments, cerebral palsy (CP, or impaired vision and hearing. Since 2006, hypothermia treatment following birth asphyxia is used in many of the Swedish neonatal units to reduce the risk of brain injury. To date, research on the experience of parenthood of the child with birth asphyxia is sparse. To improve today's neonatal care delivery, health-care providers need to better understand the experiences of becoming a parent to a child with birth asphyxia. A total of 26 parents of 16 children with birth asphyxia treated with hypothermia in a Swedish NICU were interviewed. The transcribed interview texts were analysed according to a qualitative latent content analysis. We found that the experience of becoming a parent to a child with birth asphyxia treated with hypothermia at the NICU was a strenuous journey of overriding an emotional rollercoaster, that is, from being thrown into a chaotic situation which started with a traumatic delivery to later processing the difficult situation of believing the child might not survive or was to be seriously affected by the asphyxia. The prolonged parent–infant separation due to the hypothermia treatment and parents’ fear of touching the infant because of the high-tech equipment seemed to hamper the parent–infant bonding. The adaption of the everyday life at home seemed to be facilitated by the follow-up information of the doctor after discharge. The results of this study underline the importance of family-centered support during and also after the NICU discharge.

Intelligence, birth order, and family size.

Kanazawa, Satoshi

2012-09-01

The analysis of the National Child Development Study in the United Kingdom (n = 17,419) replicates some earlier findings and shows that genuine within-family data are not necessary to make the apparent birth-order effect on intelligence disappear. Birth order is not associated with intelligence in between-family data once the number of siblings is statistically controlled. The analyses support the admixture hypothesis, which avers that the apparent birth-order effect on intelligence is an artifact of family size, and cast doubt on the confluence and resource dilution models, both of which claim that birth order has a causal influence on children's cognitive development. The analyses suggest that birth order has no genuine causal effect on general intelligence.

The aim of this study was to analyse trends of births in Spain and its Autonomous Communities (CCAA) over a 70 year period (1941-2010). The crude birth rates per 1,000 inhabitants/year were calculated by CCAA using Joinpoint regression models. Change points in trend and annual percentage of change (APC) were identified. The distribution of 38,160,305 births between 1941 and 2010 shows important changes in trends both nationally and among the CCAA. There is a general pattern for the whole country, with 5 turning points being identified with changes in trend and annual percentage change (APC). Differences are also found among regions. The analysis of trends in birth rates and the annual rates of change should enable public health authorities to properly plan pediatric care resources in our country.

Challenges and Consequences of Preterm Birth

Directory of Open Access Journals (Sweden)

Sribas Goswami

2014-11-01

Full Text Available Preterm births have been a challenge to obstetricians and paediatricians. Preterm births affect all population irrespective of age, race and economic status due to lack of seriousness and awareness among the pregnant women. Preterm birth is one of the leading causes of infant morbidity and mortality, amounting to billions of dollars each year, thus increasing the cost for health care. Proper awareness programs about preterm birth may help the women population to know and understand better the signs and symptoms of preterm labour. 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 through this study.

Thyroid disorders are common among reproductive-aged women, with hypothyroidism affecting 2 to 3% of pregnancies, and hyperthyroidism affecting an additional 0.1 to 1%. We examined associations between thyroid medications and individual birth defects using data from the National Birth Defects Prevention Study (NBDPS). The NBDPS is a multisite, population-based, case-control study that included pregnancies with estimated delivery dates from 1997 to 2011. We analyzed self-reported thyroid medication use from mothers of 31,409 birth defect cases and 11,536 unaffected controls. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using logistic regression for birth defects with five or more exposed cases, controlling for maternal age, race/ethnicity, and study center. Crude ORs and exact 95% CIs were estimated for defects with 3 to 4 exposed cases. Thyroid hormone was used by 738 (2.3%) case and 237 (2.1%) control mothers, and was associated with anencephaly (OR = 1.68; 95% CI, 1.03-2.73), holoprosencephaly (OR = 2.48; 95% CI, 1.13-5.44), hydrocephaly (1.77; 95% CI, 1.07-2.95) and small intestinal atresia (OR = 1.81; 95% CI, 1.04-3.15). Anti-thyroid medication was used by 34 (0.1%) case and 10 (<0.1%) control mothers, and was associated with aortic valve stenosis (OR = 6.91; 95% CI, 1.21-27.0). While new associations were identified, our findings are relatively consistent with previous NBDPS analyses. Our findings suggest thyroid medication use is not associated with most birth defects studied in the NBDPS, but may be associated with some specific birth defects. These results should not be interpreted to suggest that medications used to treat thyroid disease are teratogens, as the observed associations may reflect effects of the underlying thyroid disease.

Low birth weight in the United States.

Goldenberg, Robert L; Culhane, Jennifer F

2007-02-01

Pregnancy outcomes in the United States and other developed countries are considerably better than those in many developing countries. However, adverse pregnancy outcomes are generally more common in the United States than in other developed countries. Low-birth-weight infants, born after a preterm birth or secondary to intrauterine growth restriction, account for much of the increased morbidity, mortality, and cost. Wide disparities exist in both preterm birth and growth restriction among different population groups. Poor and black women, for example, have twice the preterm birth rate and higher rates of growth restriction than do most other women. Low birth weight in general is thought to place the infant at greater risk of later adult chronic medical conditions, such as diabetes, hypertension, and heart disease. Of interest, maternal thinness is a strong predictor of both preterm birth and fetal growth restriction. However, in the United States, several nutritional interventions, including high-protein diets, caloric supplementation, calcium and iron supplementation, and various other vitamin and mineral supplementations, have not generally reduced preterm birth or growth restriction. Bacterial intrauterine infections play an important role in the etiology of the earliest preterm births, but, at least to date, antibiotic treatment either before labor for risk factors such as bacterial vaginosis or during preterm labor have not consistently reduced the preterm birth rate. Most interventions have failed to reduce preterm birth or growth restriction. The substantial improvement in newborn survival in the United States over the past several decades is mostly due to better access to improved neonatal care for low-birth-weight infants.

Jensen, Sabrina; Colmorn, Lotte B; Schroll, Anne-Mette; Krebs, Lone

2017-05-01

The safety of home births has been widely debated. Observational studies examining maternal and neonatal outcomes of home births have become more frequent, and the quality of these studies has improved. The aim of the present study was to describe neonatal outcomes of home births compared with hospital births and to discuss which data are needed to evaluate the safety of home births. This was a register-based cohort study. Data on all births in Denmark (2003-2013) were collected from the Danish Medical Birth Registry (DMBR). The cohort included healthy women with uncomplicated pregnancies and no medical interventions during delivery. A total of 6,395 home births and 266,604 hospital births were eligible for analysis. Comparative analyses were performed separately in nulliparous and multiparous women. The outcome measures were neonatal mortality and morbidity. Frequencies of admission to a neonatal intensive care unit and treatment with continuous positive airway pressure were significantly lower in infants born at home than in infants born at a hospital. A slightly, but significantly increased rate of early neonatal death was found among infants delivered by nulliparous at home. This study indicates that home births in Denmark are characterized by a high level of safety owing to low rates of perinatal mortality and morbidity. Missing registration on intrapartum transfers and planned versus unplanned home births in the DMBR are, however, major limitations to the validity and utility of the reported results. Registration of these items of information is necessary to make reasonable assessments of home births in the future. none. not relevant. Articles published in the DMJ are “open access”.

Golsteyn, Bart H.H.; Magnée, Cécile A. J.

2017-01-01

This paper studies the causal effect of birth spacing (i.e., the age difference between siblings) on personality traits. We use longitudinal data from a large British cohort which has been followed from birth until age 42. Following earlier studies, we employ miscarriages between the first and second child as an instrument for birth spacing. The results show that a larger age gap between siblings negatively affects personality traits of the youngest child in two-child households. This result ...

Birth-order effects are posited by many to affect earnings and schooling. The authors show how such effects can be interpreted to shift either the earnings possibility frontier for siblings or parental preferences. The authors find empirical evidence for birth- order effects on (age-adjusted) schooling and on earnings for young U.S. adults, though the latter is not robust for all specifications. The examination of intrahousehold allocations suggests that these birth-order differences occur, d...

To compare the birth order of patients with post-traumatic stress disorder (PTSD) and adjustment disorder (AD) with population norms. 83 PTSD patients and 104 AD control patients from a psychiatric trauma clinic were diagnosed according to DCR-10 guidelines. A family history was taken as to number of siblings, and their birth order. We compared the distribution of birth order for each patient group against birth order distributions expected by chance for the same years of birth using UK population-level birth order from the Office for National Statistics. Psychiatric patients with PTSD were more likely to be from a large family, specifically to be the fifth child or later (OR 4.78, p birth order between AD patients and the general population. People with PTSD are more likely to be the youngest children from large families than expected from a random sample of people born in the same years. This association with birth order was not found for another psychiatric diagnosis AD from the same clinic. We discuss possible psychosocial and biological causes, and implications for further research.

Planned home births in the United States are associated with fewer interventions but with increased adverse neonatal outcomes such as perinatal and neonatal deaths, neonatal seizures or serious neurologic dysfunction, and low 5-minute Apgar scores. The American College of Obstetricians and Gynecologists' Committee on Obstetric Practice states that, to reduce perinatal death and to improve outcomes at planned home births, strict criteria are necessary to guide the selection of appropriate candidates for planned home birth. The committee lists 3 absolute contraindications for a planned home birth: fetal malpresentation, multiple gestations, and a history of cesarean delivery. The aim of this study was to evaluate whether there are risk factors that should be considered contraindications to planned home births in addition to the 3 that are listed by the American College of Obstetricians and Gynecologists. We conducted a population-based, retrospective cohort study of all term (≥37 weeks gestation), normal weight (≥2500 grams), singleton, nonanomalous births from 2009-2013 using the Centers for Disease Control and Prevention's period-linked birth-infant death files that allowed for identification of intended and unintended home births. We examined neonatal deaths (days 0-27 after birth) across 3 groups (hospital-attended births by certified nurse midwives, hospital-attended births by physicians, and planned home births) for 5 risk factors: 2 of the 3 absolute contraindications to home birth listed by the American College of Obstetricians and Gynecologists (breech presentation and previous cesarean delivery) and 3 additional risk factors (parity [nulliparous and multiparous], maternal age [women home births (12.1 neonatal death/10,000 deliveries; Pbirths by certified nurse midwives (3.08 neonatal death/10,000 deliveries) or physicians (5.09 neonatal death/10,000 deliveries).

Modern adverse birth outcomes may partially result from mechanisms evolved to evaluate environmental conditions and regulate maternal investment trade-offs. Male scarcity in a population is associated with a cluster of characteristics related to higher mating effort and lower paternal investment. We predicted that modern populations with male scarcity would have shorter gestational times and lower birth weights on average. We compared US Centers for Disease Control and Prevention county-aggregated year 2000 birth records with US Decennial Census data. We combined these data in a path model with the degree of male scarcity and known socio-economic predictors of birth outcomes as exogenous predictors of prematurity and low birth weight, with single mother households as a proportion of families with children as a mediator (N = 450). Male scarcity was directly associated with higher rates of low birth weight. Male scarcity made significant indirect predictions of rates of prematurity and low birth weight, as mediated by the proportion of families headed by single mothers. Aggregate socio-economic status also indirectly predicted birth outcomes, as mediated by the proportion of families headed by single mothers, whereas the proportion African American retained both direct and indirect predictions of adverse birth outcomes. Male scarcity influences life history tradeoffs, with consequences for important social and public health issues such as adverse birth outcomes. Copyright © 2013 Wiley Periodicals, Inc.

Birth weight in a large series of triplets

2011-04-01

Full Text Available Abstract Background Triplets are often born premature and with a low birth weight. Because the incidence of triplet births is rare, there are relatively few studies describing triplet birth weight characteristics. Earlier studies are often characterized by small sample sizes and lack information on important background variables such as zygosity. The objective of this study is to examine factors associated with birth weight in a large, population-based sample of triplets registered with the Netherlands Twin Register (NTR. Methods In a sample of 1230 triplets from 410 families, the effects of assisted reproductive techniques, zygosity, birth order, gestational age, sex, maternal smoking and alcohol consumption during pregnancy on birth weight were assessed. The resemblance among triplets for birth weight was estimated as a function of zygosity. Birth weight discordance within families was studied by the pair-wise difference between triplets, expressed as a percentage of the birth weight of the heaviest child. We compare data from triplets registered with the NTR with data from population records, which include live births, stillbirths and children that have deceased within days after birth. Results There was no effect of assisted reproductive techniques on triplet birth weight. At gestational age 24 to 40 weeks triplets gained on average 130 grams per week; boys weighed 110 grams more than girls and triplets of smoking mothers weighted 104 grams less than children of non-smoking mothers. Monozygotic triplets had lower birth weights than di- and trizygotic triplets and birth weight discordance was smaller in monozygotic triplets than in di- and trizygotic triplets. The correlation in birth weight among monozygotic and dizygotic triplets was 0.42 and 0.32, respectively. In nearly two-thirds of the families, the heaviest and the lightest triplet had a birth weight discordance over 15%. The NTR sample is representative for the Dutch triplet

Forced Marriage and Birth Outcomes.

Becker, Charles M; Mirkasimov, Bakhrom; Steiner, Susan

We study the impact of marriages resulting from bride kidnapping on infant birth weight. Bride kidnapping-a form of forced marriage-implies that women are abducted by men and have little choice other than to marry their kidnappers. Given this lack of choice over the spouse, we expect adverse consequences for women in such marriages. Remarkable survey data from the Central Asian nation of Kyrgyzstan enable exploration of differential birth outcomes for women in kidnap-based and other types of marriage using both OLS and IV estimation. We find that children born to mothers in kidnap-based marriages have lower birth weight compared with children born to other mothers. The largest difference is between kidnap-based and arranged marriages: the magnitude of the birth weight loss is in the range of 2 % to 6 % of average birth weight. Our finding is one of the first statistically sound estimates of the impact of forced marriage and implies not only adverse consequences for the women involved but potentially also for their children.

Home versus hospital birth--process and outcome.

2010-02-01

A constant small, but clinically important, number of American women choose to deliver at home. Contradictory professional and public policies reflect the polarization and politicization of the controversy surrounding this birth option. Women opting for home birth seek and often attain their goals of a nonmedicalized experience in comfortable, familiar surroundings wherein they maintain situational control. However, home deliveries in developed Western nations are often associated with excess perinatal and neonatal mortality, particularly among nonanomalous term infants. On the other hand, current home birth practices are, especially when birth attendants are highly trained and fully integrated into comprehensive health care delivery systems, associated with fewer cesareans, operative vaginal deliveries, episiotomies, infections, and third and fourth degree lacerations. Newborn benefits include less meconium staining, assisted ventilation, low birth weight, prematurity, and intensive care admissions. Existing data suggest areas of future research regarding the safety of home birth in the United States. Obstetricians & Gynecologists, Family Physicians. After completion of this educational activity, the participant should be better able to assess perinatal outcomes described in the reported literature associated with home births in developed countries, list potential advantages and disadvantages of planned home births, and identify confounders in current literature that impact our thorough knowledge of home birth outcomes.

To characterize the American College of Obstetricians and Gynecologists (ACOG) contraindicated home births and the women who are receiving these births in hopes of identifying venues for intervention. The National Center for Health Statistics (NCHS) birth certificate records from 1990 to 2015 were used. "Planned home births" were defined as those births in which birthplace was coded as "residence" and birth attendant was coded as "certified nurse midwife (CNM)" or "other midwife". Contraindicated home births were defined as "planned home births" from 1990 to 2015 that had one or more of the ACOG risk factors for home births, which include vaginal birth after prior cesarean delivery (VBAC), breech presentation and multiple gestations. A review of trends in contraindicated home births from 1990 to 2015 suggests that they are increasing in number (481-1396) and as a percentage of total births (0.01%-0.04%, P95%), which is most frequently initiated in the first trimester. The majority of home births were paid out-of-pocket (65%-69%). The increasing number of contraindicated home births in the United States requires public health action. Home births are likely a matter of choice rather than a lack of resources. It is unclear if women choose home births while knowing the risk or due to a lack of information. Prenatal education about contraindicated home births is possible, as almost all women receive prenatal care.

Full Text Available The purpose of the study is to research birth tourism issue. The article gives the socio-demographic and statistical aspects of research problems of birth inbound tourism in the Russian Federation. Following the literature analysis, the degree of study for birth tourism lags behind its actual size. Currently, the media has accumulated a significant amount of information on birth tourism in Russia, that requires processing, systematization and understanding that can and should become an independent area of study of sociologists and demographers to develop recommendations for the management of socio-demographic processes in birth tourism in our country. It is necessary to identify the problems that will inevitably arise. At present, this process is almost not regulated.These problems are complex, it requires the joint efforts of sociologists and demographers. However, it is impossible to obtain reliable results and to develop management decisions without attention to the statistical aspect of this problem. It is necessary to create methodological support for collecting and information processing and model development of the birth tourism. At the initial stage it is necessary to identify the direction and objectives of the analysis to determine the factors in the development of this process, to develop a hierarchical system of statistical indicators, to receive the information, needed for calculating of specific indicators.The complex research of the birth tourism issues should be based on the methodology of sociology, demography and statistics, including statistical observation, interviews with residents, structure analysis and birth tourism concentration in the country, the analysis of the dynamics, classification of factors and reasons, the grouping of regions for the development of the studied processes and, of course, the development of economic-statistical indicators.The article reveals the problem of the significant influence of the

2017-11-15

We know little about the relationship between the macroeconomy and birth outcomes, in part due to the methodological challenge of distinguishing effects of economic conditions on fetal health from effects of economic conditions on selection into live birth. We examined associations between state-level unemployment rates in the first 2 trimesters of pregnancy and adverse birth outcomes, using natality data on singleton live births in the United States during 1990-2013. We used fixed-effect logistic regression models and accounted for selection by adjusting for state-level unemployment before conception and maternal characteristics associated with both selection and birth outcomes. We also tested whether associations between macroeconomic conditions and birth outcomes differed during and after (compared with before) the Great Recession (2007-2009). Each 1-percentage-point increase in the first-trimester unemployment rate was associated with a 5% increase in odds of preterm birth, while second-trimester unemployment was associated with a 3% decrease in preterm birth odds. During the Great Recession, however, first-trimester unemployment was associated with a 16% increase in odds of preterm birth. These findings increase our understanding of the effects of the Great Recession on health and add to growing literature suggesting that macro-level social and economic factors contribute to perinatal health. © The Author(s) 2017.

Summary Preterm birth is the leading cause of perinatal morbidity and mortality worldwide, and its prevention is an important healthcare priority. Preterm parturition is one of the ‘great obstetrical syndromes’ and is caused by multiple etiologies. One of the mechanisms of disease is the untimely decline in progesterone action, which can be manifested by a sonographic short cervix in the midtrimester. The detection of a short cervix in the midtrimester is a powerful risk factor for preterm delivery. Vaginal progesterone can reduce the rate of preterm delivery by 45%, and the rate of neonatal morbidity (admission to neonatal intensive care unit, respiratory distress syndrome, need for mechanical ventilation, etc.). To prevent one case of spontaneous preterm birth birth in women with a short cervix both with and without a prior history of preterm birth. In patients with a prior history of preterm birth, vaginal progesterone is as effective as cervical cerclage to prevent preterm delivery. 17α-Hydroxyprogesterone caproate has not been shown to be effective in reducing the rate of spontaneous preterm birth in women with a short cervix.

Committee Opinion No. 697: Planned Home Birth.

Science.gov (United States)

2017-04-01

In the United States, approximately 35,000 births (0.9%) per year occur in the home. Approximately one fourth of these births are unplanned or unattended. Although the American College of Obstetricians and Gynecologists believes that hospitals and accredited birth centers are the safest settings for birth, each woman has the right to make a medically informed decision about delivery. Importantly, women should be informed that several factors are critical to reducing perinatal mortality rates and achieving favorable home birth outcomes. These factors include the appropriate selection of candidates for home birth; the availability of a certified nurse-midwife, certified midwife or midwife whose education and licensure meet International Confederation of Midwives' Global Standards for Midwifery Education, or physician practicing obstetrics within an integrated and regulated health system; ready access to consultation; and access to safe and timely transport to nearby hospitals. The Committee on Obstetric Practice considers fetal malpresentation, multiple gestation, or prior cesarean delivery to be an absolute contraindication to planned home birth.

Second-born twins on average weigh less than first-born twins and have been reported at an elevated risk of perinatal mortality. Whether the risk differences depend on their relative birth size is unknown. The present study aimed to evaluate the association of birth order with perinatal mortality by birth order-specific weight difference in twin pregnancies. In a retrospective cohort study of 258,800 twin pregnancies without reported congenital anomalies using the US matched multiple birth data 1995-2000 (the available largest multiple birth dataset), conditional logistic regression was applied to estimate the odds ratio (OR) of perinatal death adjusted for fetus-specific characteristics (sex, presentation, and birthweight for gestational age). Comparing second vs first twins, the risks of perinatal death were similar if they had similar birthweights (within 5%) and were increasingly higher if second twins weighed progressively less (adjusted ORs were 1.37, 1.90, and 3.94 if weighed 5.0-14.9%, 15.0-24.9%, and ≥25.0% less, respectively), and progressively lower if they weighed increasingly more (adjusted ORs were 0.67, 0.63, and 0.36 if weighed 5.0-14.9%, 15.0-24.9%, and ≥25.0% more, respectively) (all P birth size. Vaginal delivery at term is associated with a substantially greater risk of perinatal mortality in second twins. Copyright © 2014 Mosby, Inc. All rights reserved.

Kelsey E. Otis

2008-07-01

Full Text Available OBJECTIVES: This study investigated the low rates of hospital/health center births recorded in Yapacaní, Bolivia, that persist despite the national maternal-infant insurance program designed to ensure equitable access to free center-based health care services for pregnant women. The purpose of this study was to identify the multilevel factors inhibiting access to and utilization of public health centers for labor and delivery. METHODS: Qualitative research methods were used, including participant observation, semistructured interviews of 62 community members, and key informant interviews with eight regional experts. Data were coded and analyzed using the grounded theory approach. RESULTS: From the semistructured interview data, five reasons for the low rate of institutional births and their frequency were identified: (1 fear or embarrassment related to receiving care at a public health care center (37%; (2 poor quality of care available at the health care centers (22%; (3 distance from or other geographic issues preventing timely travel to health care services (21%; (4 economic constraints preventing travel to or utilization of health care services (14%; and (5 the perception that health care services are not necessary due to the experience of "easy birth" (6%. CONCLUSIONS: The reasons for the low rate of births in public health centers exist within the context of deficient resources, politics, and cultural differences that all influence the experience of women and their partners at the time of birth. These large scale, contextual issues must be taken into account to improve access to quality health care services for all Bolivian women at the time of birth. Resources at the national level must be carefully targeted to ensure that governmental services will successfully instill confidence in Bolivian women and facilitate their overcoming the cultural, geographic, economic, and logistical barriers to accessing "free" services.

Recent studies on date of birth of multiple sclerosis (MS) patients showed an association between month of birth and the risk of developing MS. This association has not been investigated in an African country. We aimed to determine if the risk of MS is associated with month of birth in Tunisia. Data concerning date of birth for MS patients in Tunisia (n = 1912) was obtained. Birth rates of MS patients were compared with all births in Tunisia matched by year of birth (n = 11,615,912). We used a chi-squared analysis and the Hewitt's non-parametric test for seasonality. The distribution of births among MS patients compared with the control population was not different when tested by the chi-squared test. The Hewitt's test for seasonality showed an excess of births between May and October among MS patients (p = 0.03). The peak of Births of MS patients in Tunisia was in July and the nadir in December. Our data does support the seasonality hypothesis of month of birth as risk factor for MS in Tunisia. Low vitamin D levels during pregnancy could be a possible explanation that needs further investigation. Copyright © 2015 Elsevier B.V. All rights reserved.

To evaluate the association between maternal physical activity and infant's birth weight or risk of inappropriate weight for gestational age (GA), and whether this association differs by infant's sex, maternal body mass index (BMI) or pregnancy complications in a prospective cohort study. 1913 pregnant women from the 3D Birth Cohort (Québec, Canada) completed the Pregnancy Physical Activity Questionnaire at each trimester. Energy expenditure (metabolic equivalent of task (MET)*hours/week) for total activity, sports and exercise and vigorous intensity activities was calculated. The associations with birth weight and risk of inappropriate weight for GA were evaluated by regression modelling. Interactions were tested with infant's sex, maternal prepregnancy BMI, gestational diabetes, hypertensive disorders and prematurity. Each 1 MET/hours/week increase in sports and exercise in the first trimester was associated with a 2.5 g reduction in infant's birth weight (95% CI -4.8 to -0.3) but was not associated with the risk of small weight for GA. In contrast, although not significant, a 17% reduction in the risk of large weight for GA was observed with increasing sports and exercise. Furthermore, in women with subsequent pre-eclampsia (but not normotensive or hypertensive women), each 1 MET/hours/week increment spent in any vigorous exercise in the first trimester reduced the infant's birth weight by 19.8 g (95% CI -35.2 to -4.3). Pregnant women with higher sports and exercise levels in the first trimester delivered infants with a lower birth weight. The risk of reducing infant's birth weight with vigorous exercise in women who develop pre-eclampsia later in pregnancy requires evaluation.

Born too soon: preterm birth matters.

Howson, Christopher P; Kinney, Mary V; McDougall, Lori; Lawn, Joy E

Urgent action is needed to address preterm birth given that the fi rst country-level estimates show that globally 15 million babies are born too soon and rates are increasing in most countries with reliable time trend data. As the fi rst in a supplement entitled “Born Too Soon”, this paper focuses on the global policy context. Preterm birth is critical for progress on Millennium Development Goal 4 (MDG) for child survival by 2015 and beyond, and gives added value to maternal health (MDG 5) investments also linking to non-communicable diseases. For preterm babies who survive, the additional burden of prematurity-related disability may aff ect families and health systems. Prematurity is an explicit priority in many high-income settings; however, more attention is needed especially in low- and middle-income countries where the invisibility of preterm birth as well as its myths and misconceptions have slowed action on prevention and care. Recent global attention to preterm birth hit a tipping point in 2012, with the May 2 publication of Born Too Soon: The Global Action Report on Preterm Birth and with the 2nd annual World Prematurity Day on November 17 which mobilised the actions of partners in many countries to address preterm birth and newborn health. Interventions to strengthen preterm birth prevention and care span the continuum of care for reproductive, maternal, newborn and child health. Both prevention of preterm birth and implementation of care of premature babies require more research, as well as more policy attention and programmatic investment.

A higher risk of pregnancy complications occurs after assisted reproductive techniques compared with spontaneously conceived pregnancies. This is attributed to the underlying infertility and assisted reproduction technique procedures involved during treatment. It is a matter of interest whether use of donor oocytes affects perinatal outcomes compared with pregnancies after autologous IVF. Anonymized data were obtained from the Human Fertilization and Embryology Authority. The analysis included 5929 oocyte donation and 127,856 autologous IVF live births. Data from all women who underwent donor oocyte recipient or autologous IVF cycles, both followed with fresh embryo transfer, were analysed to compare perinatal outcomes of preterm birth (PTB) and low birthweight (LBW) after singleton and multiple live births. The risk of adverse perinatal outcomes after oocyte donation was increased: adjusted OR (aOR) 1.56, 99.5% CI 1.34 to 1.80 for PTB and aOR 1.43, 99.5% CI 1.24 to 1.66 for LBW were significantly higher after oocyte donation compared with autologous IVF singletons. The adjusted odds PTB (aOR 1.21, 99.5% CI 1.02 to 1.43) was significantly higher after oocyte donation compared with autologous IVF multiple births. Analysis of this large dataset suggests significantly higher risk of PTB and LBW after ooctye donation compared with autologous IVF pregnancies. Copyright © 2017 Reproductive Healthcare Ltd.

Berthoud, R

2001-01-01

This article analyses British age-specific fertility rates by ethnic group, with a special interest in child-bearing by women below the age of 20. Birth statistics are not analysed by ethnic group, and teenage birth rates have been estimated from the dates of birth of mothers and children in the Labour Force Survey. The method appears to be robust. Caribbean, Pakistani and especially Bangladeshi women were much more likely to have been teenage mothers than white women, but Indian women were below the national average. Teenage birth rates have been falling in all three South Asian communities.

Full Text Available Arsenic, cadmium and lead are well-known environmental contaminants, and their toxicity at low concentration is the target of scientific concern. In this study, we aimed to identify the potential effects of prenatal heavy metal exposure on the birth outcomes among the Myanmar population. This study is part of a birth-cohort study conducted with 419 pregnant women in the Ayeyarwady Division, Myanmar. Face-to-face interviews were performed using a questionnaire, and maternal spot urine samples were collected at the third trimester. Birth outcomes were evaluated at delivery during the follow up. The median values of adjusted urinary arsenic, cadmium, selenium and lead concentration were 74.2, 0.9, 22.6 and 1.8 μg/g creatinine, respectively. Multivariable logistic regression revealed that prenatal cadmium exposure (adjusted odds ratio (OR = 1.10; 95% confidence interval (CI: 1.01–1.21; p = 0.043, gestational age (adjusted OR = 0.83; 95% CI: 0.72–0.95; p = 0.009 and primigravida mothers (adjusted OR = 4.23; 95% CI: 1.31–13.65; p = 0.016 were the predictors of low birth weight. The present study identified that Myanmar mothers were highly exposed to cadmium. Prenatal maternal cadmium exposure was associated with an occurrence of low birth weight.

The objective of this study was to evaluate the underlying causes of neonatal mortality (NNM) in midwife-attended home births and compare them to hospital births attended by a midwife or a physician in the United States (US). A retrospective cohort study of the Centers for Disease Control (CDC) linked birth/infant death data set (linked files) for 2008 through 2012 of singleton, term (≥37 weeks) births and normal newborn weights (≥2500 grams). Midwife-attended home births had the highest rate of neonatal deaths [122/95,657 neonatal mortality (NNM) 12.75/10,000; relative risk (RR): 3.6, 95% confidence interval (CI) 3-4.4], followed by hospital physician births (8695/14,447,355 NNM 6.02/10,000; RR: 1.7 95% CI 1.6-1.9) and hospital midwife births (480/1,363,199 NNM 3.52/10,000 RR: 1). Among midwife-assisted home births, underlying causes attributed to labor and delivery caused 39.3% (48/122) of neonatal deaths (RR: 13.4; 95% CI 9-19.9) followed by 29.5% due to congenital anomalies (RR: 2.5; 95% CI 1.8-3.6), and 12.3% due to infections (RR: 4.5; 95% CI 2.5-8.1). There are significantly increased risks of neonatal deaths among midwife-attended home births associated with three underlying causes: labor and delivery issues, infections, and fetal malformations. This analysis of the causes of neonatal death in planned home birth shows that it is consistently riskier for newborns to deliver at home than at the hospital. Physicians, midwives, and other health care providers have a professional responsibility to share information about the clinical benefits and risks of clinical management.

Risk assessment and management to prevent preterm birth.

Science.gov (United States)

Koullali, B; Oudijk, M A; Nijman, T A J; Mol, B W J; Pajkrt, E

2016-04-01

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.

Schramm, W F; Barnes, D E; Bakewell, J M

1987-08-01

A study was conducted of 4,054 Missouri home births occurring from 1978 through 1984. Of the 3,645 births whose planning status was identified, 3,067 (84 per cent) were planned to be at home. Neonatal mortality was elevated for both planned (17 observed deaths vs 8.59 expected deaths) and unplanned home births (45 observed vs 33.19 expected) compared with physician-attended hospital births. Nearly all of the mortality excess for planned home births occurred in association with lesser trained attendants (12 observed vs 4.42 expected), while for unplanned home births the excess was entirely among infants weighing 1500 grams or more (19 observed vs 3.50 expected). For planned home births attended by physicians, certified nurse-midwives, or Missouri Midwife Association recognized midwives, there was little difference between observed and expected deaths (5 observed vs 3.92 expected). There also was little difference in deaths for unplanned home births weighing less than 1500 grams (26 observed vs 29.69 expected) compared with hospital births. The study provides evidence of the importance of having skilled attendants present at planned home births.

How Neighborhood Disadvantage Reduces Birth Weight

Directory of Open Access Journals (Sweden)

Emily Moiduddin

2008-06-01

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

The New Rich and Their Unplanned Births: Stratified Reproduction under China's Birth-planning Policy.

Science.gov (United States)

Shi, Lihong

2017-12-01

This article explores the creation and ramifications of a stratified reproductive system under China's state control of reproduction. Within this system, an emerging group of "new rich" are able to circumvent birth regulations and have unplanned births because of their financial capabilities and social networks. While China's birth-planning policy is meant to be enforced equally for all couples, the unequal access to wealth and bureaucratic power as a result of China's widening social polarization has created disparate reproductive rights and experiences. This article identifies three ways in which reproductive privileges are created. It further explores how a stratified reproductive system under state population control reinforces social polarization. While many socially marginalized couples are unable to register their unplanned children for citizenship status and social benefits, the new rich are able to legitimate their births and transfer their privilege and status to their children, thus reproducing a new generation of elites. © 2016 by the American Anthropological Association.

Before the introduction of the Firearms Control Act in 2004, the epidemiology of childhood firearm injuries from 1991 to 2001 in Cape Town, South Africa, was reported. This study analyses current data as a comparator to assess the impact of the Act. Firearm injuries seen at Red Cross War Memorial Children's Hospital, Cape Town, from 2001 to 2010 were respectively reviewed. Data recorded included the patients' folder numbers, gender, date of birth, age, date of presentation, date discharged and inpatient stay, firearm type, number of shots, circumstances, injury sites, injury type, treatment, resulting morbidities and survival. These data were compared with the 1991 - 2001 data. One hundred and sixty-three children presented with firearm injuries during this period. The results showed a decrease in incidence from 2001 to 2010. Older children and males had a higher incidence than younger children and females. Most injuries were to an extremity and were unintentional. Mortality had reduced significantly from the previous study (6% to 2.6%), as did the total number of inpatient days (1 063 to 617). Compared with the earlier study, this study showed a significant reduction in the number of children presenting with a firearm-related injury. Mortality and inpatient stay were also significantly reduced. The study shows the impact that the Firearms Control Act has had in terms of paediatric firearm-related injury and provides evidence that the medical profession can play an important role in reducing violence.

How the integration of traditional birth attendants with formal health systems can increase skilled birth attendance.

Science.gov (United States)

Byrne, Abbey; Morgan, Alison

2011-11-01

Forty years of safe motherhood programming has demonstrated that isolated interventions will not reduce maternal mortality sufficiently to achieve MDG 5. Although skilled birth attendants (SBAs) can intervene to save lives, traditional birth attendants (TBAs) are often preferred by communities. Considering the value of both TBAs and SBAs, it is important to review strategies for maximizing their respective strengths. To describe mechanisms to integrate TBAs with the health system to increase skilled birth attendance and examine the components of successful integration. A systematic review of interventions linking TBAs and formal health workers, measuring outcomes of skilled birth attendance, referrals, and facility deliveries. Thirty-three articles met the selection criteria. Mechanisms used for integration included training and supervision of TBAs, collaboration skills for health workers, inclusion of TBAs at health facilities, communication systems, and clear definition of roles. Impact on skilled birth attendance depended on selection of TBAs, community participation, and addressing barriers to access. Successful approaches were context-specific. The integration of TBAs with formal health systems increases skilled birth attendance. The greatest impact is seen when TBA integration is combined with complementary actions to overcome context-specific barriers to contact among SBAs, TBAs, and women.

Birth-related acute profound hypoxic-ischaemic brain injury has specific patterns of damage including the paracentral lobules. To test the hypothesis that there is anatomically coherent regional volume loss of the corpus callosum as a result of this hemispheric abnormality. Study subjects included 13 children with proven acute profound hypoxic-ischaemic brain injury and 13 children with developmental delay but no brain abnormalities. A computerised system divided the corpus callosum into 100 segments, measuring each width. Principal component analysis grouped the widths into contiguous anatomical regions. We conducted analysis of variance of corpus callosum widths as well as support vector machine stratification into patient groups. There was statistically significant narrowing of the mid-posterior body and genu of the corpus callosum in children with hypoxic-ischaemic brain injury. Support vector machine analysis yielded over 95% accuracy in patient group stratification using the corpus callosum centile widths. Focal volume loss is seen in the corpus callosum of children with hypoxic-ischaemic brain injury secondary to loss of commissural fibres arising in the paracentral lobules. Support vector machine stratification into the hypoxic-ischaemic brain injury group or the control group on the basis of corpus callosum width is highly accurate and points towards rapid clinical translation of this technique as a potential biomarker of hypoxic-ischaemic brain injury.

Japan, which currently maintains the highest life expectancy in the world and has experienced an impressive gain in adult height over the past century, has suffered a dramatic twofold increase in low birth weight (LBW) births since the 1970s. We observed secular trends in birth characteristics using 64 115 249 live births included the vital statistics (1969-2014), as well as trends in average height among 3 145 521 adults born between 1969 and 1996, included in 79 surveys conducted among a national, subnational or community population in Japan. LBW rates exhibited a U-shaped pattern showing reductions until 1978-1979 (5.5%), after which it increased. Conversely, average adult height peaked for those born during the same period (men, 171.5 cm; women, 158.5 cm), followed by a reduction over the next 20 years. LBW rate and adult height showed a strong inverse correlation (men, r=-0.98; women, r=-0.88). A prediction model based on birth and economical characteristics estimated the national average of adult height would continue to decline, to 170.0cm (95% CI 169.6 to 170.3) for men and 157.9cm (95% CI 157.5 to 158.3) for women among those born in 2014. Adult height in Japan has started to decline for those born after 1980, a trend that may be attributed to increases in LBW births over time. Considering the known association between shorter adult height and adverse health outcomes, evidence of population-level decline in adult health due to long-term consequences of increasing LBW births in Japan is anticipated. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Maternal country of birth has been associated with perinatal health outcomes but less is known regarding breastfeeding practices in contemporary European settings. This study investigated effect of maternal country of birth on breastfeeding initiation and duration by comparing native Portuguese and migrant mothers. We analyzed data of 7065 children of the Generation XXI (GXXI) birth cohort recruited at birth (2005-06) and followed-up 4 years later. Logistic regression was used to assess the effect of maternal country of birth on breastfeeding initiation. Kaplan-Meier estimate was used to compare breastfeeding duration by maternal country of birth and length of residence by migrant mothers in Portugal. Breastfeeding initiation and the type of breastfeeding practice were similar for native Portuguese and migrant mothers. The migrants had significantly higher median duration in months of any breastfeeding (Odds Ratio [OR] 6.0, 95% Confidence Interval [CI] 5.4,6.6) and exclusive breastfeeding (OR 4.0, 95% CI 3.8,4.2) than native Portuguese mothers (OR 4.0, 95% CI 3.8,4.2 and OR 3.0, 95% CI 2.9,3.0). Migrant mothers who resided in Portugal for either ≤5 years (OR 5.0, 95% CI 3.9,6.1 and OR 4.0, 95% CI 3.8,4.2) or >  5 years (OR 6.0, 95% CI 5.5,6.5 and OR 4.0, 95% CI 3.7,4.3) years had similar duration of any breastfeeding or exclusive breastfeeding, in both cases higher than the native Portuguese mothers. No significant differences were found when world regions were compared. Maternal country of birth does not influence breastfeeding initiation and type of feeding practice. However, migrant mothers have longer breastfeeding duration of either exclusive or any breastfeeding, which was not changed by length of residence in Portugal.

Community Context, Land Use and First Birth.

Ghimire, Dirgha J; Axinn, William G

2010-09-01

This paper examines the influence of community context and land use on the monthly odds of first birth in a society in the midst of dramatic fertility transition. The theoretical framework guiding our work predicts that proximity to non-family services should delay first births by creating opportunities for competing non-family activities and spreading new ideas that change expectations about family life. On the other hand, living in agricultural settings that provide opportunities for higher returns to the child labor should speed first births. We use a longitudinal, multilevel, mixed-method data from the Nepalese Himalayas to test these predictions. The empirical results reveal that non-family services during childhood and during early adulthood both have important independent influences on the odds of first birth. Also, as predicted, a high density of agricultural land use affects the odds of first births in the opposite direction, speeding first births. This clear pattern of contrasting effects provides important new evidence of the contextual dynamics that produce watershed changes in post-marital birth timing.

A 50-fold disparity in maternal mortality exists between high- and low-income countries, and in most contexts, the single most common cause of maternal death is postpartum hemorrhage (PPH). In Bangladesh, as in many other low-income countries, the majority of deliveries are conducted at home by traditional birth attendants (TBAs) or family members. In the absence of skilled birth attendants, training TBAs in the use of misoprostol and an absorbent delivery mat to measure postpartum blood loss may strengthen the ability of TBAs to manage PPH. These complementary interventions were tested in operations research among 77,337 home births in rural Bangladesh. The purpose of this study was to evaluate TBAs' knowledge acquisition, knowledge retention, and changes in attitudes and practices related to PPH management in home births after undergoing training on the use of misoprostol and the blood collection delivery mat. We conclude that the training was highly effective and that the two interventions were safely and correctly used by TBAs at home births. Data on TBA practices indicate adherence to protocol, and 18 months after the interventions were implemented, TBA knowledge retention remained high. This program strengthens the case for community-based use of misoprostol and warrants consideration of this intervention as a potential model for scale-up in settings where complete coverage of skilled birth attendants (SBAs) remains a distant goal.

The current study sought to develop a short birth satisfaction indicator utilising items from the Birth Satisfaction Scale-Revised (BSS-R) for use as a brief measure of birth satisfaction and as a possible key performance indicator for perinatal service delivery evaluation. Building on the recently developed BSS-R, the study aimed to develop a simplified version of the instrument to assess birth satisfaction easily that could work as a short evaluative measure of clinical service delivery for labour and birth that is consistent with policy documents, placing women at the centre of the birth experience. The six item Birth Satisfaction Scale-Revised Indicator (BSS-RI) was embedded within the 2014 National Maternity Survey for England. A random selection of mothers who had given birth in a two week period in England were surveyed three months after the birth. Using a two-stage design and split-half dataset, exploratory factor analysis, confirmatory factor analysis, internal consistency, convergent, divergent and known-groups discriminant validity evaluation were conducted in a secondary analysis of the survey data. Using this large population based survey of recent mothers the short revised measure was found to comprise two distinct domains of birth satisfaction, 'stress and emotional response to labour and birth' and 'quality of care'. The psychometric qualities of the tool were robust as were the indices of validity and reliability evaluated. The BSS-RI represents a short easily administered and scored measure of women's satisfaction with care and the experience of labour and birth. The instrument is potentially useful for researchers, service evaluation and policy makers.

The multisensory approach to birth and aromatherapy.

The birth environment continues to be a subject of midwifery discourse within theory and practice. This article discusses the birth environment from the perspective of understanding the aromas and aromatherapy for the benefit of women and midwives The dynamic between the olfactory system and stimulation of normal birth processes proves to be fascinating. By examining other health models of care we can incorporate simple but powerful methods that can shape clinical outcomes. There is still more that midwives can do by using aromatherapy in the context of a multisensory approach to make birth environments synchronise with women's potential to birth in a positive way.

Paternal age at birth and the risk of obesity in young adulthood: a register-based birth cohort study of Norwegian males.

Science.gov (United States)

Eriksen, Willy; Sundet, Jon M; Tambs, Kristian

2013-01-01

The aim of this study was to determine the relationship between paternal age at birth and the risk of obesity in young adulthood. Data from the medical birth register of Norway were linked with register data from the Norwegian National Conscript Service and the national statistics agency, Statistics Norway. This study used the data on 346,609 registered males who were born at term in single birth without physical anomalies during 1967-1984 and who were examined at the time of the mandatory military conscription (age 18-20 years). The relationship between paternal age at birth and the occurrence of obesity (body mass index (BMI) ≥ 30.0 kg/m(2) ) at conscription was examined using a multinomial logistic regression analysis with BMI birth but did not increase (P = 0.52) with maternal age at birth. Men born when their fathers were 50 years or older had a 55% (95% confidence interval (CI): 14%, 110%) higher relative risk of obesity than men born when their fathers were younger than 20 years of age, after adjustment for age at conscription, birth order, birth year, maternal age at birth, the mother's total number of children, and maternal and paternal education levels. The risk of obesity in young Norwegian men increases with advancing paternal age at birth but does not increase with advancing maternal age at birth. Copyright © 2012 Wiley Periodicals, Inc.

Full Text Available From 1985 to 2013, the mean birth weight of infants in Japan decreased from 3120 g to 3000 g, and the low-birth-weight rate among live births increased from 6.3% to 9.6%. No prospective study has elucidated the risk factors for poor fetal growth and preterm birth in recent Japanese parents, such as increased parental age, maternal body figure, assisted reproductive technology (ART, and socioeconomic status. Participants were mother–infant pairs (n = 18,059 enrolled in a prospective birth cohort in Hokkaido, Japan from 2002 to 2013. Parental characteristics were obtained via self-reported questionnaires during pregnancy. Medical records helped identify very-low-birth-weight (VLBW; <1500g, term-small-for-gestational-age (term-SGA, and preterm-birth (PTB; <37 weeks infants. We calculated relative risks (RRs for PTB, VLBW, and term-SGA birth based on parental characteristics. The prevalence of PTB, VLBW, and term-SGA was 4.5%, 0.4%, and 6.5%, respectively. Aged parents and ART were risk factors for PTB and VLBW. Maternal alcohol drinking during pregnancy increased the risk; a parental educational level of ≥16 years reduced risk of term-SGA. Maternal pre-pregnancy BMI of <18.5 kg/m2 increased the risk of PTB and term-SGA. The RR for low BMI was highest among mothers who have low educational level. Among various factors, appropriate nutritional education to maintain normal BMI is important to prevent PTB and term-SGA in Japan.

Institutional and Cultural Perspectives on Home Birth in Israel

Meroz, Michal (Rosie); Gesser-Edelsburg, Anat

2015-01-01

ABSTRACT This study exposes doctors’ and midwives’ perceptions and misperceptions regarding home birth by examining their views on childbirth in general and on risk associated with home births in particular. It relies on an approach of risk communication and an anthropological framework. In a qualitative-constructive study, 19 in-depth interviews were conducted with hospital doctors, hospital midwives, home-birth midwives, and a home-birth obstetrician. Our findings reveal that hospital midwives and doctors suffer from lack of exposure to home births, leading to disagreement regarding norms and risk; it also revealed sexist or patriarchal worldviews. Recommendations include improving communication between home-birth midwives and hospital counterparts; increased exposure of hospital doctors to home birth, creating new protocols in collaboration with home-birth midwives; and establishing a national database of home births.

Where There Are (Few) Skilled Birth Attendants

Prata, Ndola; Rowen, Tami; Bell, Suzanne; Walsh, Julia; Potts, Malcolm

2011-01-01

Recent efforts to reduce maternal mortality in developing countries have focused primarily on two long-term aims: training and deploying skilled birth attendants and upgrading emergency obstetric care facilities. Given the future population-level benefits, strengthening of health systems makes excellent strategic sense but it does not address the immediate safe-delivery needs of the estimated 45 million women who are likely to deliver at home, without a skilled birth attendant. There are currently 28 countries from four major regions in which fewer than half of all births are attended by skilled birth attendants. Sixty-nine percent of maternal deaths in these four regions can be attributed to these 28 countries, despite the fact that these countries only constitute 34% of the total population in these regions. Trends documenting the change in the proportion of births accompanied by a skilled attendant in these 28 countries over the last 15-20 years offer no indication that adequate change is imminent. To rapidly reduce maternal mortality in regions where births in the home without skilled birth attendants are common, governments and community-based organizations could implement a cost-effective, complementary strategy involving health workers who are likely to be present when births in the home take place. Training community-based birth attendants in primary and secondary prevention technologies (e.g. misoprostol, family planning, measurement of blood loss, and postpartum care) will increase the chance that women in the lowest economic quintiles will also benefit from global safe motherhood efforts.

Carcinomas in children are rare and have not been well studied. We conducted a population-based case-control study and examined associations between birth characteristics and childhood carcinomas diagnosed from 28 days to 14 years during 1980-2004 using pooled data from five states (NY, WA, MN, TX, and CA) that linked their birth and cancer registries. The pooled data set contained 57,966 controls and 475 carcinoma cases, including 159 thyroid and 126 malignant melanoma cases. We used unconditional logistic regression to calculate odds ratios (ORs) and 95% confidence intervals (CIs). White compared with 'other' race was positively associated with melanoma (OR=3.22, 95% CI 1.33-8.33). Older maternal age increased the risk for melanoma (OR(per 5-year age increase)=1.20, 95% CI 1.00-1.44), whereas paternal age increased the risk for any carcinoma (OR=1.10(per 5-year age increase), 95% CI 1.01-1.20) and thyroid carcinoma (OR(per 5-year age increase)=1.16, 95% CI 1.01-1.33). Gestational age birth weight, and birth order were not significantly associated with childhood carcinomas. This exploratory study indicates that some birth characteristics including older parental age and low gestational age may be related to childhood carcinoma aetiology.

To compare perinatal outcomes, maternal outcomes, and interventions in labour by planned place of birth at the start of care in labour for women with low risk pregnancies. Prospective cohort study. England: all NHS trusts providing intrapartum care at home, all freestanding midwifery units, all alongside midwifery units (midwife led units on a hospital site with an obstetric unit), and a stratified random sample of obstetric units. 64,538 eligible women with a singleton, term (≥37 weeks gestation), and "booked" pregnancy who gave birth between April 2008 and April 2010. Planned caesarean sections and caesarean sections before the onset of labour and unplanned home births were excluded. A composite primary outcome of perinatal mortality and intrapartum related neonatal morbidities (stillbirth after start of care in labour, early neonatal death, neonatal encephalopathy, meconium aspiration syndrome, brachial plexus injury, fractured humerus, or fractured clavicle) was used to compare outcomes by planned place of birth at the start of care in labour (at home, freestanding midwifery units, alongside midwifery units, and obstetric units). There were 250 primary outcome events and an overall weighted incidence of 4.3 per 1000 births (95% CI 3.3 to 5.5). Overall, there were no significant differences in the adjusted odds of the primary outcome for any of the non-obstetric unit settings compared with obstetric units. For nulliparous women, the odds of the primary outcome were higher for planned home births (adjusted odds ratio 1.75, 95% CI 1.07 to 2.86) but not for either midwifery unit setting. For multiparous women, there were no significant differences in the incidence of the primary outcome by planned place of birth. Interventions during labour were substantially lower in all non-obstetric unit settings. Transfers from non-obstetric unit settings were more frequent for nulliparous women (36% to 45%) than for multiparous women (9% to 13%). The results support a policy

The spatial evaluation of neighborhood clusters of birth defects

Energy Technology Data Exchange (ETDEWEB)

Frisch, J.D.

1990-04-16

Spatial statistics have recently been applied in epidemiology to evaluate clusters of cancer and birth defects. Their use requires a comparison population, drawn from the population at risk for disease, that may not always be readily available. In this dissertation the plausibility of using data on all birth defects, available from birth defects registries, as a surrogate for the spatial distribution of all live births in the analysis of clusters is assessed. Three spatial statistics that have been applied in epidemiologic investigations of clusters, nearest neighbor distance, average interpoint distance, and average distance to a fixed point, were evaluated by computer simulation for their properties in a unit square, and in a zip code region. Comparison of spatial distributions of live births and birth defects was performed by drawing samples of live births and birth defects from Santa Clara County, determining the street address at birth, geocoding this address and evaluating the resultant maps using various statistical techniques. The proposed method was then demonstrated on a previously confirmed cluster of oral cleft cases. All live births for the neighborhood were geocoded, as were all birth defects. Evaluation of this cluster using the nearest neighbor and average interpoint distance statistics was performed using randomization techniques with both the live births population and the birth defect population as comparison groups. 113 refs., 36 figs., 16 tabs.

The Effect of Activity Restriction on Infant's Birth Weight and Gestational Age at Birth: PRAMS Data Analysis.

Science.gov (United States)

Omar, Abeer

2018-01-01

Activity restriction is extensively prescribed for pregnant women with major comorbidities despite the lack of evidence to support its effectiveness in preventing preterm birth or low birth weight. To determine the moderation effect of home activity restriction for more than a week on infant's birth weight and gestational age at birth for high-risk women with obstetrical and medical comorbidities. A secondary analysis of 2004-2008 New York Pregnancy Risk Assessment Monitoring System was conducted with 1426 high-risk women. High-risk group included 41% of women treated with activity restriction and 59% of those not treated with activity restriction. Women with preterm premature rupture of membrane (PPROM) who were treated with activity restriction had a lower infant birth weight ( b = -202.85, p = ≤.001) and gestational age at birth ( b = -.91, p = ≤.001) than those without activity restriction. However, women with preterm labor and hypertensive disorders of pregnancy who were not treated with activity restriction had lower infant gestational age at birth ( b = -96, p = ≤.01) and ( b = -92, p = ≤.001), respectively, compared to those who were treated with activity restriction. Findings suggest a contrary effect of activity restriction on infants born to women with PPROM, which is a major reason for prescribing activity restriction. The current study results may trigger the need to conduct randomized control trials to determine the effect of severity of activity restriction on maternal and infant outcomes.

The joy at birth: an interpretive hermeneutic literature review.

Science.gov (United States)

Crowther, Susan; Smythe, Elizabeth; Spence, Deb

2014-04-01

this literature review examines the experience of joy at birth and what that joy means. The premise is that the whole of the birthing experience has not been fully explicated in the literature and that something of significance remains unexplored and unspoken. It is argued that a hermeneutic phenomenological approach to reviewing literature provides unique insights and leads to deeper understandings about birth and the experience of joy that attunes at that moment. the philosophical underpinnings informed by Heidegger and Gadamer are central to this review and therefore the process of reviewing literature hermeneutically is described. Heideggerian phenomenology is used as the method to ask the questions of the literature in order that concealed and hidden experiences of joy at birth are made visible where they are gleaned from the literature. A hermeneutic lens is used to uncover relationships within the phenomenon of joy at birth and meaning. although a vast birth literature was reviewed joy at birth was often ignored, hidden or covered over. Reviewing the literature on relationships, professional presence, place of birth, birth satisfaction studies and birth as peak and spiritual experience provides glimpses of the phenomenon 'joy at birth'. it is argued that joy at birth remains largely neglected as a phenomenon worthy of consideration. Plausible interpretations are presented that suggest that joy at birth points to something significant and meaningful. Spiritual and sacred meaning is alluded to in the papers reviewed yet the majority of papers that investigate birth leave this meaning unspoken. The review highlights a need for further thinking and questioning about birth that would direct on-going investigation. Copyright © 2014 Elsevier Ltd. All rights reserved.

General birth-death processes: probabilities, inference, and applications

OpenAIRE

Crawford, Forrest Wrenn

2012-01-01

A birth-death process is a continuous-time Markov chain that counts the number of particles in a system over time. Each particle can give birth to another particle or die, and the rate of births and deaths at any given time depends on how many extant particles there are. Birth-death processes are popular modeling tools in evolution, population biology, genetics, epidemiology, and ecology. Despite the widespread interest in birth-death models, no efficient method exists to evaluate the fini...

Maternal nutrition and birth outcomes.

Science.gov (United States)

Abu-Saad, Kathleen; Fraser, Drora

2010-01-01

In this review, the authors summarize current knowledge on maternal nutritional requirements during pregnancy, with a focus on the nutrients that have been most commonly investigated in association with birth outcomes. Data sourcing and extraction included searches of the primary resources establishing maternal nutrient requirements during pregnancy (e.g., Dietary Reference Intakes), and searches of Medline for "maternal nutrition"/[specific nutrient of interest] and "birth/pregnancy outcomes," focusing mainly on the less extensively reviewed evidence from observational studies of maternal dietary intake and birth outcomes. The authors used a conceptual framework which took both primary and secondary factors (e.g., baseline maternal nutritional status, socioeconomic status of the study populations, timing and methods of assessing maternal nutritional variables) into account when interpreting study findings. The authors conclude that maternal nutrition is a modifiable risk factor of public health importance that can be integrated into efforts to prevent adverse birth outcomes, particularly among economically developing/low-income populations.

Association of light-to-moderate alcohol drinking in pregnancy with preterm birth and birth weight

2017-01-01

Women who drink light-to-moderately during pregnancy have been observed to have lower risk of unfavourable pregnancy outcomes than abstainers. This has been suggested to be a result of bias. In a pooled sample, including 193 747 live-born singletons from nine European cohorts, we examined...... alcohol. This decreased to 39% in 2000–2004, and 14% in 2005–2011. Before 2000, every additional drink was associated with reduced mean birth weight, whereas in 2005–2011, the mean birth weight increased with increasing intake. The period-specific associations between low-to-moderate drinking and birth...

India's Conditional Cash Transfer Programme (the JSY to Promote Institutional Birth: Is There an Association between Institutional Birth Proportion and Maternal Mortality?

Directory of Open Access Journals (Sweden)

Bharat Randive

Full Text Available India accounts for 19% of global maternal deaths, three-quarters of which come from nine states. In 2005, India launched a conditional cash transfer (CCT programme, Janani Suraksha Yojana (JSY, to reduce maternal mortality ratio (MMR through promotion of institutional births. JSY is the largest CCT in the world. In the nine states with relatively lower socioeconomic levels, JSY provides a cash incentive to all women on birthing in health institution. The cash incentive is intended to reduce financial barriers to accessing institutional care for delivery. Increased institutional births are expected to reduce MMR. Thus, JSY is expected to (a increase institutional births and (b reduce MMR in states with high proportions of institutional births. We examine the association between (a service uptake, i.e., institutional birth proportions and (b health outcome, i.e., MMR.Data from Sample Registration Survey of India were analysed to describe trends in proportion of institutional births before (2005 and during (2006-2010 the implementation of the JSY. Data from Annual Health Survey (2010-2011 for all 284 districts in above- mentioned nine states were analysed to assess relationship between MMR and institutional births.Proportion of institutional births increased from a pre-programme average of 20% to 49% in 5 years (p<0.05. In bivariate analysis, proportion of institutional births had a small negative correlation with district MMR (r = -0.11.The multivariate regression model did not establish significant association between institutional birth proportions and MMR [CI: -0.10, 0.68].Our analysis confirmed that JSY succeeded in raising institutional births significantly. However, we were unable to detect a significant association between institutional birth proportion and MMR. This indicates that high institutional birth proportions that JSY has achieved are of themselves inadequate to reduce MMR. Other factors including improved quality of care at

Michaela Kreyenfeld; Rembrandt D. Scholz; Frederik Peters; Ines Wlosnewski

2010-01-01

Until 2008, Germany’s vital statistics did not include information on the biological order of each birth. This resulted in a dearth of important demographic indicators, such as the mean age at first birth and the level of childlessness. Researchers have tried to fill this gap by generating order-specific birth rates from survey data, and by combining survey data with vital statistics. This paper takes a different approach by using hospital statistics on births to generate birth order-specific...

Genomics of Preterm Birth

Swaggart, Kayleigh A.; Pavlicev, Mihaela; Muglia, Louis J.

2015-01-01

The molecular mechanisms controlling human birth timing at term, or resulting in preterm birth, have been the focus of considerable investigation, but limited insights have been gained over the past 50 years. In part, these processes have remained elusive because of divergence in reproductive strategies and physiology shown by model organisms, making extrapolation to humans uncertain. Here, we summarize the evolution of progesterone signaling and variation in pregnancy maintenance and termination. We use this comparative physiology to support the hypothesis that selective pressure on genomic loci involved in the timing of parturition have shaped human birth timing, and that these loci can be identified with comparative genomic strategies. Previous limitations imposed by divergence of mechanisms provide an important new opportunity to elucidate fundamental pathways of parturition control through increasing availability of sequenced genomes and associated reproductive physiology characteristics across diverse organisms.

Variations in birth frequencies have an impact on activity planning in maternity wards. Previous studies of this phenomenon have commonly included elective births. A Danish study of spontaneous births found that birth frequencies were well modelled by a Poisson process. Somewhat unexpectedly, there were also weekly variations in the frequency of spontaneous births. Another study claimed that birth frequencies follow the Benford distribution. Our objective was to test these results. We analysed 50,017 spontaneous births at Akershus University Hospital in the period 1999-2014. To investigate the Poisson distribution of these births, we plotted their variance over a sliding average. We specified various Poisson regression models, with the number of births on a given day as the outcome variable. The explanatory variables included various combinations of years, months, days of the week and the digit sum of the date. The relationship between the variance and the average fits well with an underlying Poisson process. A Benford distribution was disproved by a goodness-of-fit test (p Poisson process when monthly and day-of-the-week variation is included. The frequency is highest in summer towards June and July, Friday and Tuesday stand out as particularly busy days, and the activity level is at its lowest during weekends.

Parturition pit: the bony imprint of vaginal birth

2016-01-01

To retrospectively evaluate for pits along the dorsum of the pubic body in females and compare the presence/absence of these pits to vaginal birth data. We retrospectively reviewed females with vaginal birth data who underwent pelvic CT. The presence of pits along the dorsum of the pubic body, pit grade (0 = not present; 1 = faintly imperceptible; 2 = present; 3 = prominent), and the presence of osteitis condensans ilii, preauricular sulcus, and sacroiliac joint vacuum phenomenon were assessed on imaging. Musculoskeletal radiologists who were blinded to the birth data evaluated the CTs. 48 males were also evaluated for the presence of pits. 482 female patients underwent CT pelvis and 171 were excluded due to lack of vaginal birth data. Of the 311 study patients, 262 had prior vaginal birth(s) and 194 had pits on CT. Only 7 of the 49 patients without prior vaginal birth had pits. There was a statistically significant association between vaginal birth and presence of pits (p < 0.0001). Patients with more prominent pits (grades 2/3) had a greater number of vaginal births. As vaginal deliveries increased, the odds of having parturition pits greatly increased, adjusting for age and race at CT (p < 0.0001). No males had pits. Our study indicates that parturition pits are associated with prior vaginal birth and should be considered a characteristic of the female pelvis. The lytic appearance of prominent pits on imaging can simulate disease and create a diagnostic dilemma for interpreting radiologists. (orig.)

Cervical mucus properties stratify risk for preterm birth.

Directory of Open Access Journals (Sweden)

Agatha S Critchfield

Full Text Available 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.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.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.

2009-01-01

Background Refractive status at birth is related to gestational age. Preterm babies have myopia which decreases as gestational age increases and term babies are known to be hypermetropic. This study looked at the correlation of refractive status with birth weight in term and preterm babies, and with physical indicators of intra-uterine growth such as the head circumference and length of the baby at birth. Methods All babies delivered at St. Stephens Hospital and admitted in the nursery were eligible for the study. Refraction was performed within the first week of life. 0.8% tropicamide with 0.5% phenylephrine was used to achieve cycloplegia and paralysis of accommodation. 599 newborn babies participated in the study. Data pertaining to the right eye is utilized for all the analyses except that for anisometropia where the two eyes were compared. Growth parameters were measured soon after birth. Simple linear regression analysis was performed to see the association of refractive status, (mean spherical equivalent (MSE), astigmatism and anisometropia) with each of the study variables, namely gestation, length, weight and head circumference. Subsequently, multiple linear regression was carried out to identify the independent predictors for each of the outcome parameters. Results Simple linear regression showed a significant relation between all 4 study variables and refractive error but in multiple regression only gestational age and weight were related to refractive error. The partial correlation of weight with MSE adjusted for gestation was 0.28 and that of gestation with MSE adjusted for weight was 0.10. Birth weight had a higher correlation to MSE than gestational age. Conclusion This is the first study to look at refractive error against all these growth parameters, in preterm and term babies at birth. It would appear from this study that birth weight rather than gestation should be used as criteria for screening for refractive error, especially in developing

Lisfranc injuries result from high- and low-energy mechanisms though the literature has been more focused on high-energy mechanisms. A comparison of high-energy (HE) and low-energy (LE) injury patterns is lacking. The objective of this study was to report injury patterns in LE Lisfranc joint injuries and compare them to HE injury patterns. Operative Lisfranc injuries were identified over a 5-year period. Patient demographics, mechanism of injury, injury pattern, associated injuries, missed diagnoses, clinical course, and imaging studies were reviewed and compared. HE mechanism was defined as motor vehicle crash, motorcycle crash, direct crush, and fall from greater than 4 feet and LE mechanism as athletic activity, ground level twisting, or fall from less than 4 feet. Thirty-two HE and 48 LE cases were identified with 19.3 months of average follow-up. There were no differences in demographics or missed diagnosis frequency (21% HE vs 18% LE). Time to seek care was not significantly different. HE injuries were more likely to have concomitant nonfoot fractures (37% vs 6%), concomitant foot fractures (78% vs 4%), cuboid fractures (31% vs 6%), metatarsal base fractures (84% vs 29%), displaced intra-articular fractures (59% vs 4%), and involvement of all 5 rays (23% vs 6%). LE injuries were more commonly ligamentous (68% vs 16%), with fewer rays involved (2.7 vs 4.1). LE mechanisms were a more common cause of Lisfranc joint injury in this cohort. These mechanisms generally resulted in an isolated, primarily ligamentous injury sparing the lateral column. Both types had high rates of missed injury that could result in delayed treatment. Differences in injury patterns could help direct future research to optimize treatment algorithms. Level III, comparative series.

Full Text Available Abstract Background Initiation of ventilation using high tidal volumes in preterm lambs causes lung injury and inflammation. Antenatal corticosteroids mature the lungs of preterm infants and postnatal corticosteroids are used to treat bronchopulmonary dysplasia. Objective To test if antenatal or postnatal corticosteroids would decrease resuscitation induced lung injury. Methods 129 d gestational age lambs (n = 5-8/gp; term = 150 d were operatively delivered and ventilated after exposure to either 1 no medication, 2 antenatal maternal IM Betamethasone 0.5 mg/kg 24 h prior to delivery, 3 0.5 mg/kg Dexamethasone IV at delivery or 4 Cortisol 2 mg/kg IV at delivery. Lambs then were ventilated with no PEEP and escalating tidal volumes (VT to 15 mL/kg for 15 min and then given surfactant. The lambs were ventilated with VT 8 mL/kg and PEEP 5 cmH20 for 2 h 45 min. Results High VT ventilation caused a deterioration of lung physiology, lung inflammation and injury. Antenatal betamethasone improved ventilation, decreased inflammatory cytokine mRNA expression and alveolar protein leak, but did not prevent neutrophil influx. Postnatal dexamethasone decreased pro-inflammatory cytokine expression, but had no beneficial effect on ventilation, and postnatal cortisol had no effect. Ventilation increased liver serum amyloid mRNA expression, which was unaffected by corticosteroids. Conclusions Antenatal betamethasone decreased lung injury without decreasing lung inflammatory cells or systemic acute phase responses. Postnatal dexamethasone or cortisol, at the doses tested, did not have important effects on lung function or injury, suggesting that corticosteroids given at birth will not decrease resuscitation mediated injury.

Are gestational age, birth weight, and birth length indicators of favorable fetal growth conditions? A structural equation analysis of Filipino infants.

Science.gov (United States)

Bollen, Kenneth A; Noble, Mark D; Adair, Linda S

2013-07-30

The fetal origins hypothesis emphasizes the life-long health impacts of prenatal conditions. Birth weight, birth length, and gestational age are indicators of the fetal environment. However, these variables often have missing data and are subject to random and systematic errors caused by delays in measurement, differences in measurement instruments, and human error. With data from the Cebu (Philippines) Longitudinal Health and Nutrition Survey, we use structural equation models, to explore random and systematic errors in these birth outcome measures, to analyze how maternal characteristics relate to birth outcomes, and to take account of missing data. We assess whether birth weight, birth length, and gestational age are influenced by a single latent variable that we call favorable fetal growth conditions (FFGC) and if so, which variable is most closely related to FFGC. We find that a model with FFGC as a latent variable fits as well as a less parsimonious model that has birth weight, birth length, and gestational age as distinct individual variables. We also demonstrate that birth weight is more reliably measured than is gestational age. FFGCs were significantly influenced by taller maternal stature, better nutritional stores indexed by maternal arm fat and muscle area during pregnancy, higher birth order, avoidance of smoking, and maternal age 20-35 years. Effects of maternal characteristics on newborn weight, length, and gestational age were largely indirect, operating through FFGC. Copyright © 2013 John Wiley & Sons, Ltd.

Committee Opinion No. 669 Summary: Planned Home Birth.

Science.gov (United States)

2016-08-01

In the United States, approximately 35,000 births (0.9%) per year occur in the home. Approximately one fourth of these births are unplanned or unattended. Although the American College of Obstetricians and Gynecologists believes that hospitals and accredited birth centers are the safest settings for birth, each woman has the right to make a medically informed decision about delivery. Importantly, women should be informed that several factors are critical to reducing perinatal mortality rates and achieving favorable home birth outcomes. These factors include the appropriate selection of candidates for home birth; the availability of a certified nurse-midwife, certified midwife or midwife whose education and licensure meet International Confederation of Midwives' Global Standards for Midwifery Education, or physician practicing obstetrics within an integrated and regulated health system; ready access to consultation; and access to safe and timely transport to nearby hospitals. The Committee on Obstetric Practice considers fetal malpresentation, multiple gestation, or prior cesarean delivery to be an absolute contraindication to planned home birth.

Prenatal investments, breastfeeding, and birth order.

Buckles, Kasey; Kolka, Shawna

Mothers have many opportunities to invest in their own or their child's health and well-being during pregnancy and immediately after birth. These investments include seeking prenatal care, taking prenatal vitamins, and breastfeeding. In this paper, we investigate a potential determinant of mothers' investments that has been largely overlooked by previous research-birth order. Data are from the National Longitudinal Study of Youth 1979 (NLSY79) Child and Young Adult Survey, which provides detailed information on pre- and post-natal behaviors of women from the NLSY79. These women were between the ages of 14 and 22 in 1979, and form a nationally representative sample of youth in the United States. Our sample includes births to these women between 1973 and 2010 (10,328 births to 3755 mothers). We use fixed effects regression models to estimate within-mother differences in pre- and post-natal behaviors across births. We find that mothers are 6.6 percent less likely to take prenatal vitamins in a fourth or higher-order birth than in a first and are 10.6 percent less likely to receive early prenatal care. Remarkably, mothers are 15.4 percent less likely to breastfeed a second-born child than a first, and are 20.9 percent less likely to breastfeed a fourth or higher-order child. These results are not explained by changing attitudes toward investments over time. These findings suggest that providers may want to increase efforts to encourage these behaviors at women with higher parity. The results also identify a potential mechanism for the emergence of differences in health and other outcomes across birth orders. Copyright © 2014 Elsevier Ltd. All rights reserved.

Materials and Methods: A descriptive cross-sectional study evaluating birth files in 2009–2010 of main hospitals of Isfahan, Iran. Results: Among 31640 files' studies, 614 cases of multiple birth pregnancies were investigated. The product of these pregnancies were 1286 (50.2% females infants including 557 twins (17.6/1000, 56 triplets (1.8/1000, and one case of quadruple (0.03/1000. Infants weigh <2500 g were 84.9% of all. Mothers had a mean age of 27.9 ± 4.9 which 30.4% of them had a positive history of using ART. Conclusion: The prevalence of multiple birth pregnancies is growing. The need for more mother and child care is important. Using ART world wide is leading more multiple birth which could be a cause for more complicated pregnancies.

The aim was to identify the proportion of fathers having a positive experience of a normal birth and to explore factors related to midwifery care that were associated with a positive experience. Research has mainly focused on the father's supportive role during childbirth rather than his personal experiences of birth. 595 new fathers living in a northern part of Sweden, whose partner had a normal birth, were included in the study. Data was collected by questionnaires. Odds Ratios with 95% confidence interval and logistic regression analysis were used. The majority of fathers (82%) reported a positive birth experience. The strongest factors associated with a positive birth experience were midwife support (OR 4.0; 95 CI 2.0-8.1), the midwife's ongoing presence in the delivery room (OR 2.0; 1.1-3.9), and information about the progress of labour (OR 3.1; 1.6-5.8). Most fathers had a positive birth experience. Midwifery support, the midwife's presence and sufficient information about the progress of labour are important aspects in a father's positive birth experience. The role of the midwife during birth is important to the father, and his individual needs should be considered in order to enhance a positive birth experience.

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. 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 10x10 km 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. 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. The presented study suggests that exposure to PM₂.₅ during the last month of pregnancy contributes to risks for lower birth weight and preterm birth in infants.

 The objective of this study was to investigate the relationship between preterm birth in a prior pregnancy and preterm birth in a twin pregnancy.  We performed a secondary analysis of a randomized controlled trial evaluating 17-α-hydroxyprogesterone caproate in twins. Women were classified as nulliparous, multiparous with a prior term birth, or multiparous with a prior preterm birth. We used logistic regression to examine the odds of spontaneous preterm birth of twins before 35 weeks according to past obstetric history.  Of the 653 women analyzed, 294 were nulliparas, 310 had a prior term birth, and 49 had a prior preterm birth. Prior preterm birth increased the likelihood of spontaneous delivery before 35 weeks (adjusted odds ratio [aOR]: 2.44, 95% confidence interval [CI]: 1.28-4.66), whereas prior term delivery decreased these odds (aOR: 0.55, 95% CI: 0.38-0.78) in the current twin pregnancy compared with the nulliparous reference group. This translated into a lower odds of composite neonatal morbidity (aOR: 0.38, 95% CI: 0.27-0.53) for women with a prior term delivery.  For women carrying twins, a history of preterm birth increases the odds of spontaneous preterm birth, whereas a prior term birth decreases odds of spontaneous preterm birth and neonatal morbidity for the current twin pregnancy. These results offer risk stratification and reassurance for clinicians. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

A survey was carried out in Ribeirão Preto, S. Paulo State, Brazil, between June 1978 and May 1979 with a view to studying the prevalence of low birth weight and its occurrence among different social classes. Data were collected from 8,878 singleton live births in eight maternity hospitals, accounting for 98% of all births in the area. Social classes were determinated by the use of a model proposed by Singer and modified for epidemiological purposes by Barros. Out of the 8,878 births, 660 (7.5%) were of low birth weight. The prevalence of deficient weight at birth (between 2,500 and 2,999 grams) was of 21.1%. Analysis indicated that 50.6% of children with low birth weight were at term and the majority of them suffered form intrauterine growth retardation. The prevalence of low birth weight according to social class was seen to be lower in the bourgeoisie classes (ranging from 2.8% to 3.9%) and higher in working classes (from 7% up to 9.5%). Low birth weight (defined as less than or equal to 2,500 grams) was used for purposes of comparison with other previous surveys. The percentage was lower in this study (8.3%) than that found in the Interamerican Investigation of Mortality in Childhood (8.7%), carried out in 1968-70. No statistically significant differences in the percentage of low birth weight were found in the case of Ribeirão Preto when these two surveys were compared.

Prevention of preterm birth.

LENUS (Irish Health Repository)

Flood, Karen

2012-02-01

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.

Mammalian reproductive rates vary among individuals for physiological and environmental reasons. This study aims to determine reproductive rates from an individually monitored population of wild Plains zebras Equus quagga, and to assess the sources of variability in inter-birth intervals. The animals were monitored, where possible, every six months from 2004 to 2011. Thirty nine intervals corresponding to 65 births in 26 mares were identified, using direct observations and faecal steroid monitoring. Mean foaling rate of the population is 0.74 foal/year, and comparable with the literature. There was no significant effect of mother's age, nor of the season of previous birth on the length of inter-birth intervals. Inter-birth interval was significantly longer when the first foal was a male. This finding indicates that additional costs of having a son may delay future reproduction and thus reduce the total number of offspring a mare can have during her lifetime. Individually-based data provide critical information on the determinants of reproductive rates, and are therefore a key to understanding the causes of variations in life-history traits.

Objective: This study explored the association between air pollution exposure and birth weight by using the multilevel linear model, after controlling related meteorological factors and individual differences of both mothers and babies. Methods: Women of childbearing age who were pregnant in Xi'an from 2010 to 2013, were selected as objects of this study. Multistage random sampling method was used to select 4 631 subjects followed by a self-designed questionnaire survey. Data related to quality of air and meteorology were gathered from routine monitoring system. Gestational age and date of birth, together with the average levels of air pollution were calculated for each trimester on each mother, and then the impact of air pollution on birth weight was assessed. A multilevel linear model was employed to investigate the association between the levels of exposure to air pollution by birth weight. Confounding factors were under control. We established three models in this study: Model 1 which involving the variable of air pollution exposure. Model 2 was adjusted for variables in Model 1 plus some other individual differences of both mother and baby. Model 3 was adjusted for variables in Model 2 plus meteorological factors. Results: There were significant differences seen in birth weight within the subgroups of gender, gestational age, mother's reproductive age, maternal education, residential areas and family incomes ( P 0.05). Data from Model 3 indicated that a decrease of 13.3 g(10.9 g in Model 2) and 6.6 g (5.9 g in Model 2) in birth weight that were associated with an increase of 10 μg/m(3) in the average level of NO(2) and PM(10) during the second trimester; A decrease of 13.7 g (9.8 g in Model 2) in birth weight was associated with an increase of 10 μg/m(3) in the average level of NO(2) during the third trimester. Conclusion: After controlling for meteorological factors, the levels of exposure to NO(2) and PM(10) during the second trimester and NO(2) during the

Since 1986, the reference of birth weight for gestational age has not been updated. The aim of this study was to set up Chinese neonatal network to investigate the current situation of birth weight in China, especially preterm birth weight, to develop the new reference for birth weight for gestational age and birth weight curve. A nationwide neonatology network was established in China. This survey was carried out in 63 hospitals of 23 provinces, municipalities and autonomous regions. We continuously collected the information of live births in participating hospitals during the study period of 2011-2014. Data describing birth weight and gestational age were collected prospectively. Newborn's birth weight was measured by electronic scale within 2 hours after birth when baby was undressed. The evaluation of gestational age was based on the combination of mother's last menstrual period, ultrasound in first trimester and gestational age estimation by gestational age scoring system. the growth curve was drawn by using LMSP method, which was conducted in GAMLSS 1.9-4 software package in R software 2.11.1. A total of 159 334 newborn infants were enrolled in this study. There were 84 447 male and 74 907 female. The mean birth weight was (3 232 ± 555) g, the mean birth weight of male newborn was (3 271 ± 576) g, the mean weight of female newborn was (3 188 ± 528) g. The test of the variables' distribution suggested that the distribution of gestational age and birth weight did not fit the normal distribution, the optimal distribution for them was BCT distribution. The Q-Q plot test and worm plot test suggested that this curve fitted the distribution optimally. The male and female neonatal birth weight curve was developed using the same method. Using GAMLSS method to establish nationwide neonatal birth weight curve, and the first time to update the birth weight reference in recent 28 years.

To examine maternal birth outcomes and birth experiences of low-risk women in the Netherlands in different sized midwifery practices. Descriptive study using postal questionnaires six weeks after the estimated due date. Women were recruited from urban, semi-rural and rural areas from small-sized practices (1-2 midwives), medium-sized practices (3-4 midwives) or large-sized practices (5 or more). 718 Dutch speaking women with uncomplicated pregnancies, a representative sample of women in 143 midwifery practices in the Netherlands who had given birth in the period between 20 April and 20 May 2007. Distribution of place of birth categories and intervention categories, birth experience, woman-midwife relationship and presence of own midwife after referral. Data were analyzed with Statistical Package for Social Sciences (SPSS). Women in practices with a maximum of two midwives were significantly more likely to experience lower rates of referral, interventions in general and specifically pain relief by means of pethidine, CTG registration and unplanned caesarean sections. Women with a maximum of two midwives were significantly more likely to know their midwife or midwives and were more frequently supported by their own midwife after referral in comparison to women in practices with more than two midwives. The presence of the woman's own midwife added value to the birth experience. Women with a maximum of two midwives had higher levels of a positive birth experience than women in practices with more than two midwives. Midwifery practices with a maximum of two midwives contribute to non-interventionist birth and a positive birth experience. Awareness of the study results and further study is recommended to discuss reorganization of care in order to achieve significant reductions on referral and interventions during childbirth and positive maternal birth experiences.

The objective was to examine the incidence of work accidents that required medical attention among Danish adolescents and to identify possible work environment factors associated with such accidents. We collected information in two questionnaire rounds (2004 and 2007) from a birth cohort comprising all adolescents born in 1989 (n = 3,687) living in Ringkjøbing County, Denmark. The questionnaire contained items on self-reported number of accidents and number of working hours in both rounds and on work environment factors in the second round. Approximately 5% of the adolescents who held a job, experienced a work injury at the age of 17. This equals an incidence of 65 accidents per million working hours. Most adolescents had decent working conditions, although nearly half reported that their work was heavy, monotonous or psychologically demanding. Heavy work, high psychological demands and low social support increased the risk of experiencing work injuries after adjustment for a number of factors. The incidence of work injuries among adolescents appears to be higher than the incidence among their older colleagues. Lack of social support from management significantly raised adolescents' risk of experiencing a work injury. This suggests that more direct supervision may be a good way of preventing accidents in this age group. Copyright © 2010 Wiley-Liss, Inc.

This paper describes associations among delivery-location, training of birth attendants, birthing practices, and early postpartum morbidity in women in slum areas of Dhaka, Bangladesh. During November 1993-May 1995, data on delivery-location, training of birth attendants, birthing practices, delivery-related complications, and postpartum morbidity were collected through interviews with 1,506 women, 489 home-based birth attendants, and audits in 20 facilities where the women from this study gave birth. Associations among maternal characteristics, birth practices, delivery-location, and early postpartum morbidity were specifically explored. Self-reported postpartum morbidity was associated with maternal characteristics, delivery-related complications, and some birthing practices. Dais with more experience were more likely to use potentially-harmful birthing practices which increased the risk of postpartum morbidity among women with births at home. Postpartum morbidity did not differ by birth-location. Safe motherhood programmes must develop effective strategies to discourage potentially-harmful home-based delivery practices demonstrated to contribute to morbidity.

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.

Perinatal events can influence the development of asthma in childhood but current evidence is contradictory concerning the effects on life-time asthma risk. To assess the relationship between birth characteristics and asthma from childhood to adulthood. All available birth records for the Tasmanian Longitudinal Health Study (TAHS) cohort, born in 1961 were obtained from the Tasmanian State Archives and Tasmanian hospitals. Low birth weight (LBW) was defined as less than 2500 grams. Preterm birth was defined as delivery before 37 weeks' gestation. Small for gestational age (SGA) was defined as a birth weight below the 10 th percentile for a given gestational age. Multivariate logistic and cox regression were used to examine associations between birth characteristics and lifetime risk of current and incident asthma, adjusting for confounders. The prevalence of LBW was 5.2%, SGA was 13.8% and preterm was 3.3%. LBW (OR = 1.65, 95%CI 1.12,2.44) and preterm birth (OR = 1.81, 95%CI 0.99, 3.31) were both associated with an increased risk of current asthma between the ages of 7 to 43 years. There was no association between SGA and current asthma risk. However, SGA was associated with incident asthma (HR = 1.32, 95%CI 1.00, 1.74), and there was an interaction with sex (p value = 0.08), with males having a greater risk of incident asthma (HR = 1.70, 95%CI 1.16-2.49) than females (HR = 1.04, 95%CI 0.70-1.54). Preterm birth and LBW were associated with an increased risk of current asthma into middle-age. These findings are the first to demonstrate the continuing impact of these characteristics on asthma risk into middle-age.

Women perceive what birth is even before they are pregnant for the first time. Part of this conceptualization is the basic belief about birth as a medical and natural process. These two separate beliefs are pivotal in the decision-making process about labor and birth. Adapting Engel's biopsychosocial framework, we explored the importance of a wide range of factors which may contribute to these beliefs among first-time mothers. This observational study included 413 primiparae ≥24 weeks' gestation, recruited in medical centers and in natural birth communities in Israel. The women completed a questionnaire which included the Birth Beliefs Scale and a variety of biopsychosocial characteristics such as obstetric history, birth environment, optimism, health-related anxiety, and maternal expectations. Psychological dispositions were more related to the birth beliefs than the social or biomedical factors. Sociodemographic characteristics and birth environment were only marginally related to the birth beliefs. The basic belief that birth is a natural process was positively related to optimism and to conceiving spontaneously. Beliefs that birth is a medical process were related to pessimism, health-related anxiety, and to expectations that an infant's behavior reflects mothering. Expectations about motherhood as being naturally fulfilling were positively related to both beliefs. Psychological factors seem to be most influential in the conceptualization of the beliefs. It is important to recognize how women interpret the messages they receive about birth which, together with their obstetric experience, shape their beliefs. Future studies are recommended to understand the evolution of these beliefs, especially within diverse cultures. © 2017 Wiley Periodicals, Inc.

To determine the rates of births in adolescent pregnant women in diferent regions of Thailand and assess the rates of complications occurring at pregnancy, childbirth, and postpartum in women admitted in the hospitals ofThailand. The secondary analysis of data from pregnant women aged 10 to 49 years, who were admitted to hospitals and recorded in the National Health Security Office database between October 2010 and September 2011 was carried out. Adolescent birth rate by the regions and rate of complications ofpregnancy, delivery, and postpartum by age groups were analyzed. Highest birth rate was found among women aged 19 years (58.3 per 1, 000 population). The distribution of adolescent births varied across regions of Thailand, which was high in central region. Rate of preterm delivery was highest (10%) in adolescent aged 10 to 14 years. Rate of diabetes mellitus (6%), preeclampsia (4%), and postpartum hemorrhage (3%) among women aged 35 to 49 years were substantially higher than those among women aged 34 years or less. Adolescent birth rate varied across regions of Thailand. Complications occurred differently by ages of women. Holistic policy and planning strategies for proper prevention and management among pregnant women in different age groups are needed

This article examines one of the relevant concepts in the current debate on home birth-autonomy in place of birth-and its uses in general language, ethics, and childbirth health care literature. International discussion on childbirth services. A concept analysis guided by the model of Walker and Avant. The authors suggest that autonomy in the context of choosing place of birth is defined by three main attributes: information, capacity and freedom; given the antecedent of not harming others, and the consequences of accountability for the outcome. Model, borderline and contrary cases of autonomy in place of birth are presented. A woman choosing place of birth is autonomous if she receives all relevant information on available choices, risks and benefits, is capable of understanding and processing the information and choosing place of birth in the absence of coercion, provided she intends no harm to others and is accountable for the outcome. The attributes of the definition can serve as a useful tool for pregnant women, midwives, and other health professionals in contemplating their moral status and discussing place of birth.

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.

Crude and intrinsic birth rates for Asian countries.

Rele, J R

1978-01-01

An attempt to estimate birth rates for Asian countries. The main sources of information in developing countries has been census age-sex distribution, although inaccuracies in the basic data have made it difficult to reach a high degree of accuracy. Different methods bring widely varying results. The methodology presented here is based on the use of the conventional child-woman ratio from the census age-sex distribution, with a rough estimate of the expectation of life at birth. From the established relationships between child-woman ratio and the intrinsic birth rate of the nature y = a + bx + cx(2) at each level of life expectation, the intrinsic birth rate is first computed using coefficients already computed. The crude birth rate is obtained using the adjustment based on the census age-sex distribution. An advantage to this methodology is that the intrinsic birth rate, normally an involved computation, can be obtained relatively easily as a biproduct of the crude birth rates and the bases for the calculations for each of 33 Asian countries, in some cases over several time periods.

Primiparity is a well-established and significant risk factor for postpartum psychosis and especially bipolar affective disorders. However, no studies have, to our knowledge, quantified the risk of psychiatric disorders after the first, second, or subsequent births. The overall aim of the present study was to study the risk of first-time psychiatric episodes requiring inpatient treatment after the birth of the first, second, or third child. A cohort comprising 750,127 women was defined using information from Danish population registries. Women were followed individually from the date of birth of their first, second, or third child through the following 12 months over the period 1970-2011. The outcome of interest was defined as first-time admissions to a psychiatric hospital with any type of psychiatric disorder. Women who had a first psychiatric episode which required inpatient treatment after their first (n = 1,327), second (n = 735), or third (n = 238) delivery were included. The highest risk was found in primiparous mothers 10-19 days postpartum [relative risk (RR) = 8.65; 95% confidence interval (CI): 6.89-10.85]. After the second birth, the highest risk was at 60-89 days postpartum (RR = 2.01; 95% CI: 1.52-2.65), and there was no increased risk after the third birth. The effect of primiparity was strongest for bipolar disorders. Primiparity is a significant risk factor for experiencing a first-time episode with a psychiatric disorder, especially bipolar disorders. A second birth was associated with a smaller risk, and there was no increased risk after the third birth. The risk of postpartum episodes after the second delivery increased with increasing inter-pregnancy intervals, a result which warrants further investigation. © 2013 John Wiley & Sons A/S.

Background Observational epidemiological studies indicate that maternal height is associated with gestational age at birth and fetal growth measures (i.e., shorter mothers deliver infants at earlier gestational ages with lower birth weight and birth length). Different mechanisms have been postulated to explain these associations. This study aimed to investigate the casual relationships behind the strong association of maternal height with fetal growth measures (i.e., birth length and birth weight) and gestational age by a Mendelian randomization approach. Methods and Findings We conducted a Mendelian randomization analysis using phenotype and genome-wide single nucleotide polymorphism (SNP) data of 3,485 mother/infant pairs from birth cohorts collected from three Nordic countries (Finland, Denmark, and Norway). We constructed a genetic score based on 697 SNPs known to be associated with adult height to index maternal height. To avoid confounding due to genetic sharing between mother and infant, we inferred parental transmission of the height-associated SNPs and utilized the haplotype genetic score derived from nontransmitted alleles as a valid genetic instrument for maternal height. In observational analysis, maternal height was significantly associated with birth length (p = 6.31 × 10−9), birth weight (p = 2.19 × 10−15), and gestational age (p = 1.51 × 10−7). Our parental-specific haplotype score association analysis revealed that birth length and birth weight were significantly associated with the maternal transmitted haplotype score as well as the paternal transmitted haplotype score. Their association with the maternal nontransmitted haplotype score was far less significant, indicating a major fetal genetic influence on these fetal growth measures. In contrast, gestational age was significantly associated with the nontransmitted haplotype score (p = 0.0424) and demonstrated a significant (p = 0.0234) causal effect of every 1 cm increase in maternal

Although out-of-hospital births are still relatively rare in the United States, it is important to monitor trends in these births, as they can affect patterns of facility usage, clinician training, and resource allocation, as well as health care costs. Trends and characteristics of home and birth center births are analyzed to more completely profile contemporary out-of-hospital births in the United States. National birth certificate data were used to examine a recent increase in out-of-hospital births. After a gradual decline from 1990 to 2004, the number of out-of-hospital births increased from 35,578 in 2004 to 47,028 in 2010. In 2010, 1 in 85 US infants (1.18%) was born outside a hospital; about two-thirds of these were born at home, and most of the rest were born in birth centers. The proportion of home births increased by 41%, from 0.56% in 2004 to 0.79% in 2010, with 10% of that increase occurring in the last year. The proportion of birth center births increased by 43%, from 0.23% in 2004 to 0.33% in 2010, with 14% of the increase in the last year. About 90% of the total increase in out-of hospital births from 2004 to 2010 was a result of increases among non-Hispanic white women, and 1 in 57 births to non-Hispanic white women (1.75%) in 2010 was an out-of-hospital birth. Most home and birth center births were attended by midwives. Home and birth center births in the United States are increasing, and the rate of out-of-hospital births is now at the highest level since 1978. There has been a decline in the risk profile of out-of-hospital births, with a smaller proportion of out-of-hospital births in 2010 than in 2004 occurring to adolescents and unmarried women and fewer preterm, low-birth-weight, and multiple births. © 2013 This article is a U.S. Government work and is in the public domain in the United States.

To evaluate recent trends of out-of-hospital births in the US from 2009 to 2014. We accessed data for all live births occurring in the US from the National Vital Statistics System, Natality Data Files for 2009-2014 through the interactive data tool, VitalStats. Out-of-hospital (OOH) births in the US increased from 2009 to 2014 by 80.2% from 32,596 to 58,743 (0.79%-1.47% of all live births). Home births (HB) increased by 77.3% and births in freestanding birthing centers (FBC) increased by 79.6%. In 2014, 63.8% of OOH births were HB, 30.7% were in FBC, and 5.5% were in other places, physicians offices, or clinics. The majority of women who had an OOH birth in 2014 were non-Hispanic White (82.3%). About in one in 47 non-Hispanic White women had an OOH in 2014, up from 1 in 87 in 2009. Women with a HB were older compared to hospital births (age ≥35: 21.5% vs. 15.4%), had a higher live birth order(≥5: 18.9% vs. 4.9%), 3.48% had infants home and in freestanding birthing centers has significantly increased in the US making it the country with the most out of hospital births among all developed countries. The root cause of the increase in planned OOH births should be identified and addressed by the medical community.

Previously we identified associations between the mother's air pollution exposure and birth weight for births in Connecticut and Massachusetts from 1999-2002. Other studies also found effects, though results are inconsistent. We explored potential uncertainties in earlier work and further explored associations between air pollution and birth weight for PM 10 , PM 2.5 , CO, NO 2 , and SO 2 . Specifically we investigated: (1) whether infants of younger (≤24 years) and older (≥40 years) mothers are particularly susceptible to air pollution's effects on birth weight; (2) whether the relationship between air pollution and birth weight differed by infant sex; (3) confounding by co-pollutants and differences in pollutants' measurement frequencies; and (4) whether observed associations were influenced by inclusion of pre-term births. Findings did not indicate higher susceptibility to the relationship between air pollution and birth weight based on the mother's age or the infant's sex. Results were robust to exclusion of pre-term infants and co-pollutant adjustment, although sample size decreased for some pollutant pairs. These findings provide additional evidence for the relationship between air pollution and birth weight, and do not identify susceptible sub-populations based on infant sex or mother's age. We conclude with discussion of key challenges in research on air pollution and pregnancy outcomes.

India accounts for 19% of global maternal deaths, three-quarters of which come from nine states. In 2005, India launched a conditional cash transfer (CCT) programme, Janani Suraksha Yojana (JSY), to reduce maternal mortality ratio (MMR) through promotion of institutional births. JSY is the largest CCT in the world. In the nine states with relatively lower socioeconomic levels, JSY provides a cash incentive to all women on birthing in health institution. The cash incentive is intended to reduce financial barriers to accessing institutional care for delivery. Increased institutional births are expected to reduce MMR. Thus, JSY is expected to (a) increase institutional births and (b) reduce MMR in states with high proportions of institutional births. We examine the association between (a) service uptake, i.e., institutional birth proportions and (b) health outcome, i.e., MMR. Data from Sample Registration Survey of India were analysed to describe trends in proportion of institutional births before (2005) and during (2006-2010) the implementation of the JSY. Data from Annual Health Survey (2010-2011) for all 284 districts in above- mentioned nine states were analysed to assess relationship between MMR and institutional births. Proportion of institutional births increased from a pre-programme average of 20% to 49% in 5 years (phigh institutional birth proportions that JSY has achieved are of themselves inadequate to reduce MMR. Other factors including improved quality of care at institutions are required for intended effect.

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

This study aimed to examine the potential association between maternal PBDEs and birth outcomes, including birth weight (g), length (cm), head circumference (cm) and gestational age (week). 215 mothers were recruited from a prospective birth cohort in rural northern China between September 2010 and February 2012. Serum PBDE congeners were detected and their association with birth outcomes were examined. The median maternal serum concentrations of BDE-28, -47, -99, -100, -153 were 2.27, 2.26, 3.58, 2.13, 4.87 ng/g lipid, respectively. Maternal LgBDE-28 and LgBDE-100 were negatively associated with birth length (β = −0.92, 95% confidence interval (CI): −1.82, −0.02; β = −0.97, 95% CI: −1.83, −0.08). A negative association was found between LgBDE-28 and birth weight among male infants (β = −253.76, 95% CI: −438.16, −69.36). PBDE congeners were not associated with head circumference, or gestational age. Our results contribute to growing evidence suggesting that PBDEs have adverse effects on birth outcomes. - Highlights: • We examined the relations between maternal exposure to PBDEs and birth outcomes. • BDE-28, -47, -99, -100, and -153 were detected in serum from 215 pregnant women. • There was a negative association between BDE-28, -100 and birth length. • BDE-28 showed a negative association with birth weight among male infants. - Negative associations were found between BDE-28, -100 exposure and birth length as well as between BDE-28 exposure and birth weight in male infants.

Higher than normal sex ratios at birth in China have been reported since the early 1980's. This study aimed to investigate recent trends in sex ratio at birth in Hangzhou, capital of Zhejiang Province in southeast China. Information on selected maternal and birth-related characteristics was extracted from the Hangzhou Birth Information Database for all pregnant women who delivered live births during 2005-2014. The sex ratios at birth were calculated after excluding infants with missing data on gender and those born with ambiguous genitalia. A total of 478,192 male births and 430,852 female births were recorded giving an overall ratio of 111.0. The sex ratio at birth was almost constant at around 110.7 during the period 2005-2008, followed by an increase to the peak at 113.1 in 2010 and then declined back to 109.6 in 2014. The gender ratio at birth in Hangzhou remained unbalanced for the past decade.

Construct updated birth weight-for-gestational age centile charts for use in the UK and compare these to the currently used UK-WHO charts. Secondary analysis of national birth data. Centiles were constructed using 1 269 403 singleton births occurring in England and Wales in 2013-2014 as part of the MBRRACE-UK national perinatal surveillance programme. These were then validated using 642 737 singleton births occurring in England and Wales in 2015. Sex-specific birth weight-for-gestational age centiles. Centiles were created using the lambda-mu-sigma method via the GAMLSS package in R. This method transforms the skewed birth weight distribution to approximate a normal distribution, allowing any birth weight centile to be produced. The new centiles performed well in the validation sample, with the observed and expected proportion of births below a given centile in agreement. Overall, driven by the predominance of term births, the UK-WHO charts classify a smaller proportion of infants as below a given centile. For example, the UK-WHO estimates classified only 1.32% (8035/606 430) of term infants born in 2015 as below the second centile, compared with 1.97% (11 975/606 430) using the new MBRRACE-UK centiles. At the earliest gestational ages, however, the opposite is observed, with the UK-WHO classifying a larger proportion of infants as below a given centile, particularly at the lower end of the birthweight distribution. We have constructed and validated updated birth weight-for-gestational age centiles using a contemporary sample of births occurring in England and Wales. The benefits of these updated centiles will be first to assist the national surveillance of perinatal mortality programme by improving the identification of the proportion of stillbirths and neonatal deaths affected by intrauterine growth restriction and, second, to aid clinicians by more accurately identifying babies who require increased monitoring in the period immediately following birth. �

The Burden of Provider-Initiated Preterm Birth and Associated Factors: Evidence from the Brazilian Multicenter Study on Preterm Birth (EMIP.

Full Text Available About 15 million children are born under 37 weeks of gestation worldwide. Prematurity is the leading cause of neonatal deaths and short/long term morbidities, entailing consequences not only for the individual, but also their family, health agencies, facilities and all community. The provider-initiated preterm birth is currently one of the most important obstetric conditions related to preterm births, particularly in middle and high income countries, thus decreasing the need for therapeutic preterm birth is essential to reduce global prematurity. Therefore detailed knowledge on the factors associated with provider-initiated preterm birth is essential for the efforts to reduce preterm birth rates and its consequences. In this current analysis we aimed to assess the proportion of provider-initiated (pi-PTB among preterm births in Brazil and identify associated factors.This is an analysis of a multicenter cross-sectional study with a nested case-control component called Brazilian Multicenter Study on Preterm Birth (EMIP. EMIP was conducted in 20 referral obstetric hospitals located in the three most populated of the five Brazilian regions. We analysed data of women with pi-PTB, defined as childbirth occurring at less than 37 weeks, medically indicated for maternal/fetal compromise or both; and women with term birth, childbirth at or after 37 weeks. Maternal, sociodemographic, obstetric, prenatal care, delivery, and postnatal characteristics were assessed as possible factors associated with pi-PTB, compared to term births. The overall prevalence of preterm births was 12.3%. Of these, approximately one-third of cases were initiated by the provider. Hypertensive disorders, placental abruption, and diabetes were the main maternal conditions leading to pi-PTB. Caesarean section was the most common mode of delivery.

ABSTRACT Preterm birth increases the risk of adverse birth outcomes and is the leading cause of neonatal mortality. A significant cause of preterm birth is in utero infection with vaginal microorganisms. These vaginal microorganisms are often recovered from the amniotic fluid of preterm birth cases. A vaginal microorganism frequently associated with preterm birth is group B streptococcus (GBS), or Streptococcus agalactiae. However, the molecular mechanisms underlying GBS ascension are poorly understood. Here, we describe the role of the GBS hyaluronidase in ascending infection and preterm birth. We show that clinical GBS strains associated with preterm labor or neonatal infections have increased hyaluronidase activity compared to commensal strains obtained from rectovaginal swabs of healthy women. Using a murine model of ascending infection, we show that hyaluronidase activity was associated with increased ascending GBS infection, preterm birth, and fetal demise. Interestingly, hyaluronidase activity reduced uterine inflammation but did not impact placental or fetal inflammation. Our study shows that hyaluronidase activity enables GBS to subvert uterine immune responses, leading to increased rates of ascending infection and preterm birth. These findings have important implications for the development of therapies to prevent in utero infection and preterm birth. PMID:27353757

I examined time trends in low birth weight (LBW) and very low birth weight (VLBW) among interracial compared with single-race infants. Using natality data from 1978 through 1997 for singleton births to black and white parents, I calculated relative risks (RRs) of LBW and VLBW for interracial compared with single-race births, stratified by maternal race and adjusted for maternal characteristics. Among black mothers, interracial births had lower risks of LBW and VLBW than single-race births, and RRs were similar throughout the time period [for example, adjusted RR = 0.76 and 95% confidence interval (CI) = 0.73-0.80 for LBW in 1994-1997]. Among white mothers, interracial infants had higher risks of LBW than single-race infants; however, the adjusted RRs declined over the time period, from 1.22 (95% CI = 1.19-1.27) in 1978-1981 to 1.05 (95% CI = 1.03-1.08) in 1994-1997. Since 1978, there has been some relative improvement in birth outcomes for infants of white mothers and black fathers compared with single-race white births. There was, however, no relative improvement for black mother/black father infants relative to black mother/white father births.
