  7. From institutionalized birth to home birth

    Directory of Open Access Journals (Sweden)

    2014-06-01

    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.

    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.

    1970-09-04

    1) Eric Blair (alias George Orwell) can rest easy in his grave, because birth control by governmentally imposed methods, such as incorporation of a contraceptive agent into drinking water, is totally unfeasible by 1984. 2) Fundamentally new birth control procedures in the female (for example, a once-a-month luteolytic or abortifacient agent) and a male contraceptive pill probably will not be developed until the 1980's at the earliest, and then only if major steps of the type outlined in this article are instituted in the early 1970's. Development during the next decade of practical new methods of birth control without important incentives for continued active participation by the pharmaceutical industry is highly unlikely. If none are developed, birth control in 1984 will not differ significantly from that of today.

  15. 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.

  16. 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.

  17. Unsanctioned births in China.

    Science.gov (United States)

    Li, L; Ballweg, J A

    1995-05-01

    This study hypothesizes that "unsanctioned" births (beyond the limit authorized by the government) in China are more likely among couples who have strong traditional fertility norms and less likely among couples who adopt new family planning norms. The theoretical framework is based on cultural conflict theory as developed by Sellin. Data are obtained from 6654 ever married women aged under 49 years from the 1987 In-Depth Fertility Survey for Guangdong province. Over 30% of the sample were married before 20 years of age. 20% had 1 child, 26.7% had 2 children, about 23% had 3 children, 13.9% had 4 children, and under 10% had 5 or more children. The average number of living children was 2.5. Findings reveal that socioeconomic status was significantly related to unsanctioned births; they were more common in less developed areas and among women of lower socioeconomic status (SES). Persons living in areas with a high monetary contribution per person in family planning efforts at the county level were less likely to have unsanctioned births. Women who lived in urban areas, worked in state enterprises, and had parents with high educational status were less likely to have unsanctioned births. They were more likely among women who married at an early age, lived with parents after the marriage, had female living children, and had failed pregnancies. They were also more likely among women who had arranged marriages, a traditional desire for large family sizes, an early marriage ideal, and a preference for sons. Knowledge of family planning and greater use of abortion were related to a lower incidence of unsanctioned births. Women who talked with their husbands about their family size desires were less likely to have unsanctioned births. Parental educational attainment only had an influence among rural women. Variables impacted on fertility differently in urban and rural areas.

  13. How menstrual shame affects birth.

    Science.gov (United States)

    Moloney, Sharon

    2010-12-01

    In Western, industrialised culture, menstruation and birth are commonly seen as unstable, pathological processes requiring medical control. Girls learn to see menstruation as shameful and secretive. Menarche is a nodal event around which girls' beliefs and attitudes to being female are organised. The perception of menstruation as a liability has foundational implications for future female experiences, particularly birth. Other cultures have recognised menstruation and birth as spiritual phenomena, with menarche and childbirth experienced as powerful initiatory processes. My PhD research explored the links between cultural attitudes to menstruation and spirituality, and women's experiences of birth. My feminist perspective recognised the power imbalances, patriarchal controls and structural inequities that oppress women in their intimate body experiences. Menstrual shame was identified as a core patriarchal organising principle that inculcates and perpetuates male dominance and female subordination. Engendering the perception of female physiology - and thus womanhood - as inherently flawed, menstrual shame was a key factor that predisposed women to approach birth feeling fearful, disempowered and vulnerable to intervention. However, my research also unearthed a counter-cultural group of women who had transformed their relationship with both menstruation and birth. Redesignating menstruation as a spiritual phenomenon enabled these women to dismantle their menstrual shame, connect with their female spirituality and give birth fearlessly and powerfully. For others, the profound spirituality of birth transformed their understanding of menstruation. Contrary to cultural norms, both menstruation and birth can be sacred female experiences which are sources of authority and empowerment.

  14. Birth control over 30.

    Science.gov (United States)

    Asnes, M

    1994-07-01

    Among 30-40 year old women, 40% of pregnancies are unplanned, which is indicative of the unreliability of the birth control methods they are using. The 1992 Ortho Birth Control Study interviewed almost 7000 women, of whom 8% listed withdrawal and 4% listed the rhythm method. These two methods have failure rates of 24% and 19%, respectively. Birth control methods often disappoint the users and increasingly they turn to sterilization. 48% of married women aged 15-44 had themselves been sterilized or had a sterilized partner in the Ortho survey. Although reversal of tubal ligation succeeds in 43-88% of cases, conception cannot be guaranteed. For women over the age of 30 who are healthy and do not smoke, low-estrogen or no-estrogen oral contraceptive pills are considered safe. Taking the pill also helps prevent ovarian and endometrial cancer. The failure rate is 6%. Barrier methods also offer protection from sexually transmitted diseases including HIV. Condoms are favored by 33% of unmarried women and 19% of married women. Sexually active 40-44 year old unmarried women run a 14-19% risk of contracting a sexually transmitted disease (STD) in a 12-month period. Diaphragms offer some protection against STDs, but their failure rate is 18%. IUDs are regaining popularity, but only 1% of women use them (ParaGard T380A or Progestasert). Pelvic inflammatory disease is the reason: a 1992 study showed that 0.97% of women developed it within 20 days of use. Norplant is a long-term implant containing levonorgestrel with a failure rate of 0.5%. A 1993 study followed 1253 implant users over 12 months and found a very low rate of pregnancy, but 75% experienced some side effects during the first year. About half of the women using Norplant removed it after 2.5 years because of irregular bleeding. Depo-Provera is an injectable administered every 3 months, but after removal it can take up to a year for ovulation to return. Side effects may include hair loss and weight gain; and links to

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.

    Full Text Available To have an, idea about the relation between the length of birth interval and lactation, and birth control program this study have been done. The material for such analysis was nomad women's fertility history that was in their reproductive period (15-44. The material itself was gathered through a health survey. The main sample was composed of 2,165 qualified women, of whom 49 due to previous or presently using contraceptive methods and 10 for the lack of enough data were excluded from 'this study. Purpose of analysis was to find a relation between No. of live births and pregnancies with total duration of married life (in other word, total months which the women were at risk of pregnancy. 2,106 women which their fertility history was analyzed had a totally of272, 502 months married life. During this time 8,520 live births did occurred which gave a birth interval of 32 months. As pregnancy termination could be through either live birth, still birth or abortion (induced or spontaneous, bringing all together will give No. of pregnancies which have occurred during this period (8,520 + 124 + 328 = 8,972 with an average of interpregnancy interval of 30.3 months. Considering the length of components of birth interval: Post partum amenorrhea which depends upon lactation. - Anovulatory cycles (2 month - Ooulatory exposure, in the absence of contraceptive methods (5 months - Pregnancy (9 months.Difference between the length, of birth interval from the sum of the mentioned period (except the first component, (2 + 5+ 9 = 16 will be duration of post partum amenorrhea (32 - 16 = 16, or in other word duration of breast feeding among nomad women. In this study it was found that, in order to reduce birth by 50% a contraceptive method with 87% effectiveness is needed.

    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.

    Intrauterine infection is an important cause of some birth defects worldwide. The most common pathogens include rubella virus, cytomegaloviurs, ureaplasma urealyticum, toxoplasma, etc. General information about these pathogens in epidemiology, consequence of birth defects, and the possible mechanisms in the progress of birth defects, and the interventions to prevent or treat these pathogens' infections are described. The infections caused by rubella virus, cytomegaloviurs, ureaplasma urealyticum, toxoplasma, etc. are common, yet they are proved to be fatal during the pregnant period, especially during the first trimester. These infections may cause sterility, abortion, stillbirth, low birth weight, and affect multiple organs that may induce loss of hearing and vision, even fetal deformity and the long-term effects. These pathogens' infections may influence the microenvironment of placenta, including levels of enzymes and cytokines, and affect chondriosome that may induce the progress of birth defect. Early diagnosis of infections during pregnancy should be strengthened. There are still many things to be settled, such as the molecular mechanisms of birth defects, the effective vaccines to certain pathogens. Birth defect researches in terms of etiology and the development of applicable and sensitive pathogen detection technology and methods are imperative.

    2013-09-01

    Hypnobirthing is often regarded as a method of pain relief without drugs. This is to miss the point, as it presupposes that pain is there in the first place. When a woman learns to release the preconceptions, fears and worries about birth that are endemic in our society, her experience of giving birth to her baby can be the most wonderful and empowering experience of her life. Mind and body working together can be a powerful and efficient combination. This is how birth is designed to be, as midwives and hospitals are beginning to discover. Thus hypnobirthing can provide a service that women want as well as save scarce NHS funds.

    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. Discussion This study, for the first time, depicts a national panorama of labour and birth

    2016-01-01

    OBJECTIVE The purpose of this study was to examine associations between diabetes mellitus and 39 birth defects. STUDY DESIGN This was a multicenter case-control study of mothers of infants who were born with (n = 13,030) and without (n = 4895) birth defects in the National Birth Defects Prevention Study (1997–2003). RESULTS Pregestational diabetes mellitus (PGDM) was associated significantly with noncardiac defects (isolated, 7/23 defects; multiples, 13/23 defects) and cardiac defects (isolated, 11/16 defects; multiples, 8/16 defects). Adjusted odds ratios for PGDM and all isolated and multiple defects were 3.17 (95% CI, 2.20–4.99) and 8.62 (95% CI, 5.27–14.10), respectively. Gestational diabetes mellitus (GDM) was associated with fewer noncardiac defects (isolated, 3/23 defects; multiples, 3/23 defects) and cardiac defects (isolated, 3/16 defects; multiples, 2/16 defects). Odds ratios between GDM and all isolated and multiple defects were 1.42 (95% CI, 1.17–1.73) and 1.50 (95% CI, 1.13–2.00), respectively. These associations were limited generally to offspring of women with prepregnancy body mass index ≥25 kg/m2. CONCLUSION PGDM was associated with a wide range of birth defects; GDM was associated with a limited group of birth defects. PMID:18674752

    Full Text Available Background: Congenital anomalies of urinary system are common and are found in 3-4% of population, and lethal urinary anomalies account for 10% of termination of pregnancy. Methods: A study was done to know the incidence of congenital anomalies at birth for the period of 4 months from May 99 - Sept 99 at Cheluvamba hospital attached to Mysore medical college. Congenital anomalies in the still births, live births and aborted fetuses >20 weeks were studied along with the case history and ultrasound reports. Aborted fetuses and still born babies were collected for autopsy after the consent of parents. These babies were fixed in 10% formalin and autopsy was done after fixing, and anomalies were noted. Results: Total births during study period were 3000. There were 61 babies with congenital anomalies and 6 babies had anomalies of urinary system. Among the urinary system anomalies 1 baby had bilateral renal agenesis, 1 baby had unilateral renal agenesis with anophthalmia (Fraser syndrome, 2 babies had Multicystic dysplastic kidney disease (MCDK and 1 live baby had hydronephrosis due to obstruction at pelvi ureteric junction, and 1 live female baby had polycystic kidneys. Conclusion: Incidence of urinary system anomalies in the present study was 2 per 1000 births. U/S detection of urinary anomalies varies with period of gestation, amniotic fluid volume and visualisation of urinary bladder. Autopsy helps to detect renal agenesis.

    Effective and coordinated teamworking is key to achieving safe birth for mothers and babies. Confidential enquiries have repeatedly identified deficiencies in teamwork as factors contributing to poor maternal and neonatal outcomes. The ingredients of a successful multi-professional team are varied, but research has identified some fundamental teamwork behaviours, with good communication, proficient leadership and situational awareness at the heart. Simple, evidence-based methods in teamwork training can be seamlessly integrated into a core, mandatory obstetric emergency training. Training should be an enjoyable, inclusive and beneficial experience for members of staff. Training in teamwork can lead to improved clinical outcomes and better birth experience for women.

    The high vulnerability of incarcerated women is worsened when they are pregnant and give birth during imprisonment. This article traces the profile of incarcerated women living with their children in female prison units of the capitals and metropolitan regions of Brazil and describes pregnancy and childbirth conditions and healthcare practices while in incarceration. This study is an analysis of a series of cases resultant from a national census conducted between August 2012 and January 2014. This analysis included 241 mothers. Of these, 45% were younger than 25 years old, 57% were dark skinned, 53% had studied less than eight years and 83% were multiparous. At the time of incarceration, 89% were already pregnant and two thirds did not want the current pregnancy. Access to prenatal care was inadequate for 36% of the women. During their hospital stay, 15% referred to having suffered some type of violence (verbal, psychological, or physical). Only 15% of the mothers rated the care received during their hospital stay as excellent. They had low social/familial support and more than one third reported the use of handcuffs during their hospital stay. Incarcerated mothers received poorer healthcare during pregnancy and birth when compared with non-incarcerated users of the public sector. This study also found violations of human rights, especially during birth.

  11. BIRTH WEIGHT : A COMMUNITY PERSPECTIVE

    Directory of Open Access Journals (Sweden)

    J P SRIVASTAVA

    2003-06-01

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

In spite of the establishment of hospitals and health centres, it is to these traditional healers and TBAs that the majority of people turn in times of sickness and child-birth. Approximately 60 percent of all deliveries in Malawi occur in the villages. It is therefore important that due regard be paid to the activities of these traditional practitioners in order to ensure the achievement of the goal - "Health for all by the year 2000". The training of TBAs is seen as part of the Maternal and Child Health Services in the country.

  18. Allostatic Load and Preterm Birth

    Directory of Open Access Journals (Sweden)

    David M. Olson

    2015-12-01

    Full Text Available Preterm birth is a universal health problem that is one of the largest unmet medical needs contributing to the global burden of disease. Adding to its complexity is that there are no means to predict who is at risk when pregnancy begins or when women will actually deliver. Until these problems are addressed, there will be no interventions to reduce the risk because those who should be treated will not be known. Considerable evidence now exists that chronic life, generational or accumulated stress is a risk factor for preterm delivery in animal models and in women. This wear and tear on the body and mind is called allostatic load. This review explores the evidence that chronic stress contributes to preterm birth and other adverse pregnancy outcomes in animal and human studies. It explores how allostatic load can be used to, firstly, model stress and preterm birth in animal models and, secondly, how it can be used to develop a predictive model to assess relative risk among women in early pregnancy. Once care providers know who is in the highest risk group, interventions can be developed and applied to mitigate their risk.

    Full Text Available BACKGROUND: The space and time distribution of risk factors for allergic diseases may provide insights into disease mechanisms. Allergy is believed to vary by month of birth, but multinational studies taking into account latitude have not been conducted. METHODS AND FINDINGS: A questionnaire was distributed in 54 centres to a representative sample of 20- to 44-y-old men and women mainly in Europe but also including regions in North Africa, India, North America, Australia, and New Zealand. Data from 200,682 participants were analyzed. The median prevalence of allergic rhinitis was 22%, with a substantial variation across centres. Overall, allergic rhinitis decreased with geographical latitude, but there were many exceptions. No increase in prevalence during certain winters could be observed. Also, no altered risk by birth month was found, except borderline reduced risks in September and October. Effect estimates obtained by a multivariate analysis of total and specific IgE values in 18,085 individuals also excluded major birth month effects and confirmed the independent effect of language grouping. CONCLUSION: Neither time point of first exposure to certain allergens nor early infections during winter months seems to be a major factor for adult allergy. Although there might be effects of climate or environmental UV exposure by latitude, influences within language groups seem to be more important, reflecting so far unknown genetic or cultural risk factors.

    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.

  1. 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.

    Scientists using the Hubble telescope have been amazed by the number of stars being created in galaxy NGC 3310. But while some scientists are observing the birth of new stars, others are predicting the end of the universe. According to supersymmetry it is possible that the universe could spontaneously change to a state where the electric force is switched off, resulting in the disintegration of all matter. Called 'vacuum fluctuation', this event is even less likely than winning the lottery jackpot twice in the same day however (1/2 page).

    Full Text Available Observations of the burial places of newborns at the prehistoric site at Lepenski Vir (Serbia revealed the possibility that deliveries took place inside houses that were heated. Warm houses provided a thermally stable environment which, in turn, could solve the problem of thermoregulation, that is critical for the survival of babies. In this study it is shown that the creation of these good conditions for giving birth could have been an important step in human evolution that could have led to a demographic expansion.

    Full Text Available Meningitis is an acute inflammation of the protective membranes covering the brain and spinal cord, which are known as the meninges. This infection may be caused by Streptococcus pneumonia bacteria. In this study, we presented the case of a female newborn with meningitis secondary to Streptococcus pneumonia. Her birth weight and height were normal. After 24 hours of birth, the neonate was diagnosed with tachypnea, without presenting any signs of fever or respiratory distress. The newborn was referred to Sheikh Children's Hospital, where chest X-ray showed clear lungs with no evidence of abnormality. Furthermore, the cardiothoracic ratio was normal. A complete blood count demonstrated white blood cell (WBC count of 5400/uL. In Blood/Culcture ratio (B/C test, Streptococcus pneumonia was reported, and the results of the cerebrospinal fluid (CSF analysis confirmed this result. Following 14 days of receiving antibiotic therapy, the results of CSF analysis were within the normal range. Her visual and hearing examinations were normal, and demonstrated improved situation. The infant was discharged with exclusive breastfeeding.

    Full Text Available Background: The rate of primary cesarean section (CS is on the rise. More and more women report with a history of a previous CS. A trial of vaginal delivery can save these women from the risk of repeat CS. Aims: The study was conducted to assess the safety and success rate of vaginal birth after CS (VBAC in selected cases of one previous lower segment CS (LSCS. Materials and Methods: The prospective observational study was carried out in a tertiary care teaching hospital over a period of two years. One hundred pregnant women with a history of one previous LSCS were enrolled in the study. Results: In the present study, 85% cases had a successful VBAC and 15% underwent a repeat emergency LSCS for failed trial of vaginal delivery. Cervical dilatation of more than 3 cm at the time of admission was a significant factor in favor of a successful VBAC. Birth weight of more than 3,000 g was associated with a lower success rate of VBAC. The incidence of scar dehiscence was 2% in the present study. There was no maternal or neonatal mortality. Conclusion: Trial of VBAC in selected cases has great importance in the present era of the rising rate of primary CS especially in rural areas.

    Birth outcomes of two groups of socially disadvantaged mothers at risk for adverse birth outcomes, one receiving prebirth assistance from a certified doula and the other representing a sample of birthing mothers who elected to not work with a doula, were compared. All of the mothers were participants in a prenatal health and childbirth education program. Expectant mothers matched with a doula had better birth outcomes. Doula-assisted mothers were four times less likely to have a low birth weight (LBW) baby, two times less likely to experience a birth complication involving themselves or their baby, and significantly more likely to initiate breastfeeding. Communication with and encouragement from a doula throughout the pregnancy may have increased the mother's self-efficacy regarding her ability to impact her own pregnancy outcomes.

    2015-01-01

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

    We investigate the Entanglement Sudden Birth (ESB) of two Heisenberg spins A and B. The third controller, qutrit C is introduced, which only has the Dzyaloshinskii-Moriya (DM) spin-orbit interaction with qubit B. We find that the DM interaction is necessary to induce the Entanglement Sudden Birth of the system qubits A and B, and the initial states of the system qubits and the qurit C are also important to control its Entanglement Sudden Birth.

    2010-04-01

    Full Text Available This study examines the relationships between alcohol taxation, drinking during pregnancy, and infant health. Merged data from the US Natality Detailed Files, as well as the Behavioral Risk Factor Surveillance System (1985–2002, data regarding state taxes on beer, wine, and liquor, a state- and year-fixed-effect reduced-form regression were used. Results indicate that a one-cent ($0.01 increase in beer taxes decreased the incidence of low-birth-weight by about 1–2 percentage points. The binge drinking participation tax elasticity is −2.5 for beer and wine taxes and −9 for liquor taxes. These results demonstrate the potential intergenerational impact of increasing alcohol taxes.

    2005-04-19

    The generation of cells in the human body has been difficult to study and our understanding of cell turnover is limited. Extensive testing of nuclear weapons resulted in a dramatic global increase in the levels of the isotope {sup 14}C in the atmosphere, followed by an exponential decrease after the test ban treaty in 1963. We show that the level of {sup 14}C in genomic DNA closely parallels atmospheric levels, and can be used to establish the time point when the DNA was synthesized and cells were born. We use this strategy to determine the age of cells in the cortex of the adult human brain, and show that whereas non-neuronal cells are exchanged, occipital neurons are as old as the individual, supporting the view that postnatal neurogenesis does not take place in this region. Retrospective birth dating is a generally applicable strategy that can be used to measure cell turnover in man under physiological and pathological conditions.

    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.

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

    The Traditional Birth Attendants (TBAs) Survey in Swaziland was undertaken between March 27th 1996 and April 8th 1996. The objective of the survey was to generate reliable information regarding activities of TBAs in Swaziland. The survey was conducted in 25 Chiefdoms sampled out of a total of 206 Chiefdoms registered in Swaziland. The total number of sampled respondents in the 25 Chiefdoms was 721. From the survey, it is estimated that there were probably 3000 TBAs in the country, and in the majority of cases such TBAs would be a 51-year old woman who herself had delivered six children and had worked as a TBA for at least 10 years. Between 9,000 and 12,000 deliveries are estimated to take place out of health facilities. Of these many, nearly 43.5% are assisted by "TBAs"; 16.3% of woman interviewed deliver relative/family member and 15.1% are assisted by friends/neighbours, etc. Some of TBAs carry out procedures which are considered to be potentially harmful. Nearly 30% of TBAs have administered herbs; 45% attend to abnormal deliveries (breech and multiple pregnancies); 26.7% re-use their cord cutting tools and in the case of haemorrhage 23.4% do manual procedures within reproductive tract of delivering women.

    The aim of the investigation was to determine the dynamic of birth delivery and relate to dental occlusion among a group of adult subjects. The group studied was made up of 106 subjects (57 females and 49 males) referred for dental diagnosis and treatment. The average age was 26 with a range 22 to 30 years. In data collection and analysis the following were used as measures: dental occlusion (Angle Class I, II div 1, II div 2 and III) and type of delivery (normal, short, long, caesarean and other). Results showed that among 106 subjects 72 (68%) had malocclusion versus 34 (32%) with normal occlusion; 24 subjects (22.6%) have been normal delivery versus 82 (77.4%) with non-normal delivery. Class I is present in 34 subjects (32%), class II division 1 in 26 (24%), class II division 2 in 22. (20%), class III in 16 (14%), and 8 subjects (6%) fall in the section "other". Among 24 subjects with normal delivery 100% presented class I occlusion. However, among 82 subjects with non-normal delivery 10 subjects had a class I (12.2%) and the 72 (87.8%) had in the other classes, are distributed in the various subgroups of non-normal labor/delivery. None of the subjects with a malocclusion have a normal labor/delivery. Better understanding of the connections among osteopathic theory, craniosacral treatment and the outcomes upon dental occlusion, more rigorous evaluations are warranted.

  10. Prediction of preterm birth in twins.

    Makrydimas, George; Sotiriadis, Alexandros

    2014-02-01

    About 13% of twins are born before 34 weeks and 7% before 32 weeks. The prediction of preterm birth in twins is based on the same tests as in singleton pregnancies. In twin pregnancies, the cut-off for short cervix at the second trimester scan is less than 25 mm (compared with 15 mm in singletons); length less than 20 mm is associated with 42% risk for birth before 32 weeks and cervical length less than 25 mm is associated with 28% risk for birth before 28 weeks. The measurement of cervical length in pregnancies with symptoms of preterm labour may have limited accuracy in predicting preterm birth. In asymptomatic women, a positive fetal fibronectin test seems to be associated with 35% risk for birth before 32 weeks and 40% risk for birth less than 34 weeks, whereas a negative test decreases the risk to 6% and 17%, respectively. The differences in the predictive value of tests between twins and singletons reflect the diverse pathophysiology of preterm birth between the two groups.

  11. Anthropometric measurements for detecting low birth weight

    2013-05-01

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

Providing analgesia to the vulva and anus, it is used for operative vaginal birth and subsequent repair, late second stage pain relief with spontaneous vaginal birth, repair of complex lacerations, or repair of lacerations in women who are unable to achieve adequate or satisfactory pain relief during perineal repair with local anesthesia. Key to its efficacy is the knowledge of pudendal nerve anatomy, the optimal point of infiltration of local anesthetic, and an understanding of the amount of time necessary to effect adequate analgesia.

    The purpose of this Roy adaptation model-based multi-site international mixed method study was to examine the relations of type of caesarean birth (unplanned/planned), number of caesarean births (primary/repeat), and preparation for caesarean birth to women's perceptions of and responses to caesarean birth. The sample included 488 women from the United States (n = 253), Finland (n = 213), and Australia (n = 22). Path analysis revealed direct effects for type of and preparation for caesarean birth on responses to caesarean birth, and an indirect effect for preparation on responses to caesarean birth through perception of birth the experience.

  17. The Birth Environment of the Solar System

    CERN Document Server

    Adams, Fred C

    2010-01-01

    This paper reviews our current understanding of the possible birth environments of our Solar System. Since most stars form within groups and clusters, the question becomes one of determining the nature of the birth aggregate of the Sun. This discussion starts by reviewing Solar System properties that provide constraints on our environmental history. We then outline the range of star-forming environments that are available in the Galaxy, and discuss how they affect star and planet formation. The nature of the solar birth cluster is constrained by many physical considerations, including radiation fields provided by the background environment, dynamical scattering interactions, and by the necessity of producing the short-lived radioactive nuclear species inferred from meteoritic measurements. Working scenarios for the solar birth aggregate can be constructed, as discussed herein, although significant uncertainties remain.

    This study extended research on birth order and erotic preferences by examining birth order in a sample of pedophiles. Charts of 338 pedophiles, assessed from 1980-1994 in the Behavioural Sexology Department of the Clarke Institute of Psychiatry in Toronto, were reviewed for family-demographic information. In total, 170 (57 heterosexual pedophiles, 68 homosexual pedophiles, and 45 bisexual pedophiles) of these men had sufficient sibling information to be included in the analyses. The results indicated that homosexual-bisexual pedophiles had a later birth order than heterosexual pedophiles and that this effect was primarily the result of the homosexual-bisexual group being born later among their brothers. The results extend previous findings that homosexual men, regardless of sample composition, have a later birth order than comparable groups of heterosexual men. The results also challenge some existing theories on the nature and origins of pedophilia.

    Live birth has evolved many times independently in vertebrates, such as mammals and diverse groups of lizards and snakes. However, live birth is unknown in the major clade Archosauromorpha, a group that first evolved some 260 million years ago and is represented today by birds and crocodilians. Here we report the discovery of a pregnant long-necked marine reptile (Dinocephalosaurus) from the Middle Triassic (∼245 million years ago) of southwest China showing live birth in archosauromorphs. Our discovery pushes back evidence of reproductive biology in the clade by roughly 50 million years, and shows that there is no fundamental reason that archosauromorphs could not achieve live birth. Our phylogenetic models indicate that Dinocephalosaurus determined the sex of their offspring by sex chromosomes rather than by environmental temperature like crocodilians. Our results provide crucial evidence for genotypic sex determination facilitating land-water transitions in amniotes. PMID:28195584

    The objective of this study was to provide trained labor support (doulas) to pregnant women in jail. A multiagency intervention project provided doula birth services to pregnant women in urban jails. Program evaluation included interviews with women and written satisfaction surveys of providers and correctional officers. A convenience sample of 18 incarcerated women received doula services. A doula visited each woman in jail antepartum to review expectations for labor and birth; during hospitalization, the doula provided continuous support throughout labor and birth. Doulas visited women postpartum to review birth events. Surveys administered to providers and officers demonstrated high satisfaction with the program. Qualitative interviews with 14 women indicated unanimous support for the services and documented women's major concerns. Findings support offering doula services to all pregnant women in custody and expanding doula services to include early and comprehensive intervention coordinated by nurses.

  9. Birth and Evolution of Isolated Radio Pulsars

    CERN Document Server

    Faucher-Giguere, C A

    2005-01-01

    We investigate the birth and evolution of Galactic isolated radio pulsars. We begin by estimating their birth space velocity distribution from proper motion measurements of Brisken et al. (2002, 2003). We find no evidence for multimodality of the distribution and favor one in which the absolute one-dimensional velocity components are exponentially distributed and with a three-dimensional mean velocity of 380^{+40}_{-60} km s^-1. We then proceed with a Monte Carlo-based population synthesis, modelling the birth properties of the pulsars, their time evolution, and their detection in the Parkes and Swinburne Multibeam surveys. We present a population model that appears generally consistent with the observations. Our results suggest that pulsars are born in the spiral arms, with a Galactocentric radial distribution that is well described by the functional form proposed by Yusifov & Kucuk (2004), in which the pulsar surface density peaks at radius ~3 kpc. The birth spin period distribution extends to several h...

    In this paper, we consider birth-death processes on a tree T and we are interested when it is regular, recurrent and ergodic (strongly, exponentially). By constructing two corresponding birth death processes on Z+, we obtain computable conditions sufficient or necessary for that (in many cases, these two conditions coincide). With the help of these constructions, we give explicit upper and lower bounds for the Dirichlet eigenvalue λ0. At last, some examples are investigated to justify our results.

    2015-01-01

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

    THIS year, Women of China asked two 30-year-old women from the Yimeng mountain area in Shandong Province about their chosen methods of birth control. Both women reported using intrauterine devices (IUDs), which they had placed by local gynecologists at the hospital 40 days after giving birth. Are these women aware of other contraceptive methods? Some rural women tell us they know of other methods such as oral contraception, contraceptive implants and tubal ligation.

  13. Kids having kids: the teen birth rate.

    Science.gov (United States)

    Noonan, S S

    1997-08-01

    This article focuses on adolescent pregnancy and birth issues in the US. Although the birth rate among adolescents aged 10-19 years in New Jersey declined to 9609 infants per year in 1994, a decline of 7% from 1990, there remain concerns about the welfare of the mother and fetal development. Adolescent birth rates in New Jersey are higher for Black youths compared to White youths (100/1000 births vs. 25.4/1000). During 1990-94, births to girls aged 10-14 years increased from 241 to 284. There are many reasons for teenage pregnancy: abuse or coercion, peer pressure, misinformation, defiant behavior, person whims, and need for success through pregnancy. Pregnant teens frequently do not receive adequate prenatal care, maintain good nutrition, and/or refrain from unhealthy habits such as cigarette smoking, alcohol drinking, and/or drug use. The lack of prenatal care until late pregnancy may be due to lack of health insurance coverage or money for transportation. Teenagers have higher rates of premature births. Fetal development may be impaired due to lack of a proper maternal diet with a sufficient amount of folic acid, iron and protein, or food intake. Teenagers have twice the rate of spina bifida. Girls need to know the facts about the risk of premature birth and low birth weight associated with their cigarette smoking during pregnancy. Girls should be asked to reduce smoking to 3-5 cigarettes per week by the next visit and to stop entirely by the following visit. Teenagers need reinforcement in adopting the right eating patterns and curbing undesirable habits. Prenatal care should be comprehensive. The evidence suggests that fetal development is hampered by the competition for resources between the mother and fetus. Health care professionals must provide contraceptives and education; most hope that the repetitive cycle of repeat pregnancy and poverty does not continue.

  16. Birth Territory: a theory for midwifery practice.

    Science.gov (United States)

    Fahy, Kathleen M; Parratt, Jenny Anne

    2006-07-01

    The theory of Birth Territory describes, explains and predicts the relationships between the environment of the individual birth room, issues of power and control, and the way the woman experiences labour physiologically and emotionally. The theory was synthesised inductively from empirical data generated by the authors in their roles as midwives and researchers. It takes a critical post-structural feminist perspective and expands on some of the ideas of Michel Foucault. Theory synthesis was also informed by current research about the embodied self and the authors' scholarship in the fields of midwifery, human biology, sociology and psychology. In order to demonstrate the significance of the theory, it is applied to two clinical stories that both occur in hospital but are otherwise different. This analysis supports the central proposition that when midwives use 'midwifery guardianship' to create and maintain the ideal Birth Territory then the woman is most likely to give birth naturally, be satisfied with the experience and adapt with ease in the post-birth period. These benefits together with the reduction in medical interventions also benefit the baby. In addition, a positive Birth Territory is posited to have a broader impact on the woman's partner, family and society in general.

  17. Challenges and Consequences of Preterm Birth

    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.

    The number eight is considered lucky in Chinese culture, e.g. the Beijing Olympics began at 8:08 pm on 8/8/2008. Given the potential for discretion in selecting particular dates of labor induction or scheduled Cesarean section (C-section), we consider whether Chinese-American births in California occur disproportionately on the 8th, 18th, or 28th day of the month. We find 2.3% "too many" Chinese births on these auspicious birth dates, whereas Whites show no corresponding increase. The increase in Chinese births is driven by higher parity C-sections: the number of repeat C-sections is 6% "too high" on auspicious birth dates. Sons born to Chinese parents account for the entire increase; daughter deliveries do not seem to be timed to achieve "lucky" birth dates. We also find avoidance of repeat C-section deliveries on the 4th, 14th, and 24th of the month, considered unlucky in Chinese culture. Finally, we replicate earlier work finding that Friday the 13th delivery dates are avoided and document a particularly large decrease among Chinese. For Whites and Chinese in California, mothers with higher levels of education are particularly likely to avoid delivering on the 13th.

  19. Brazilian multicentre study on preterm birth (EMIP: prevalence and factors associated with spontaneous preterm birth.

    Renato Passini

    Full Text Available BACKGROUND: Preterm birth rate is increasing and is currently a worldwide concern. The purpose of this study was to estimate the prevalence of preterm birth in a sample of health facilities in Brazil and to identify the main risk factors associated with spontaneous preterm births. METHODS AND FINDINGS: This was a multicentre cross sectional study on preterm births in 20 referral obstetric hospitals with a case-control component to identify factors associated with spontaneous preterm birth. Surveillance was implemented at all centres to identify preterm births. For eligible consenting women, data were collected through a post-delivery questionnaire completed with information from all mother-newborn medical records until death or discharge or at a maximum of 60 days post-delivery, whichever came first. The risk of spontaneous preterm birth was estimated with OR and 95%CI for several predictors. A non-conditional logistic regression analysis was then performed to identify independently associated factors. The overall prevalence of preterm birth was 12.3%. Among them, 64.6% were spontaneous and 35.4% therapeutic. In the case-control component, 2,682 spontaneous preterm births were compared to a sample of 1,146 term births. Multivariate analyses identified the following as risk factors for spontaneous preterm birth among women with at least one previous birth: a previous preterm birth (ORadj = 3.19, 2.30-4.43, multiple pregnancy (ORadj = 29.06, 8.43-100.2, cervical insufficiency (ORadj = 2.93, 1.07-8.05, foetal malformation (ORadj = 2.63, 1.43-4.85, polyhydramnios (ORadj = 2.30, 1.17-4.54, vaginal bleeding (ORadj = 2.16, 1.50-3.11, and previous abortion (ORadj = 1.39, 1.08-1.78. High BMI (ORadj = 0.94, 0.91-0.97 and weight gain during gestation (ORadj = 0.92, 0.89-0.95 were found to be protective factors. CONCLUSIONS: The preterm birth rate in these health facilities in Brazil is high and spontaneous preterm births

  20. Birth control for new parents.

    Jimenez, S L

    1994-09-01

    The author describes a range of contraceptive methods, and their side effects, which may be acceptable for new parents. The methods are the oral contraceptive pill, Norplant, Depo-Provera, and intrauterine devices (IUD). Natural methods and permanent contraception are options described in insets. The author notes that differences in the effectiveness rates among available types of oral contraceptive pills are small enough not to merit consideration when deciding which kind of pill may be appropriate. Combination birth control pills are taken daily at the same time for 21 out of 28 days. Combination pills are not recommended for women with a history of hypertension or other cardiovascular diseases, thrombophlebitis, migraine headaches, diabetes, active gallbladder disease, or mononucleosis. Any hormonal method may be particularly risky for smokers over age 35. The mini-pill, containing a smaller amount of progesterone and no estrogen, is taken every day and is also on a 28-day cycle. Containing no estrogen, the mini-pill is often recommended for women who are nursing, who are over age 35, or who suffer from hypertension or migraines. Both adverse and positive side effects may be experienced from use. Norplant is the brand name of a contraceptive system which releases progesterone from under the skin of a woman's upper arm over the course of a five-year period. The system has a theoretical effectiveness rate of more than 99%, although the duration of effectiveness may be less than five years in overweight women. The most common side effect is irregular bleeding, and removal is often a longer and more difficult procedure than insertion. The most commonly used injectable hormonal contraceptive is Depo-Provera, a progesterone solution which works for up to three months. The majority of users experience some side effects. Finally, IUDs are highly effective and need to be replaced only every 1-10 years depending upon how they are made. Women typically experience

    Science.gov (United States)

    2016-06-01

    Approximately 0.5% of all births occur before the third trimester of pregnancy, and these very early deliveries result in the majority of neonatal deaths and more than 40% of infant deaths. A recent executive summary of proceedings from a joint workshop defined periviable birth as delivery occurring from 20 0/7 weeks to 25 6/7 weeks of gestation. When delivery is anticipated near the limit of viability, families and health care teams are faced with complex and ethically challenging decisions. Multiple factors have been found to be associated with short-term and long-term outcomes of periviable births in addition to gestational age at birth. These include, but are not limited to, nonmodifiable factors (eg, fetal sex, weight, plurality), potentially modifiable antepartum and intrapartum factors (eg, location of delivery, intent to intervene by cesarean delivery or induction for delivery, administration of antenatal corticosteroids and magnesium sulfate), and postnatal management (eg, starting or withholding and continuing or withdrawing intensive care after birth). Antepartum and intrapartum management options vary depending upon the specific circumstances but may include short-term tocolytic therapy for preterm labor to allow time for administration of antenatal steroids, antibiotics to prolong latency after preterm premature rupture of membranes or for intrapartum group B streptococci prophylaxis, and delivery, including cesarean delivery, for concern regarding fetal well-being or fetal malpresentation. Whenever possible, periviable births for which maternal or neonatal intervention is planned should occur in centers that offer expertise in maternal and neonatal care and the needed infrastructure, including intensive care units, to support such services. This document describes newborn outcomes after periviable birth, provides current evidence and recommendations regarding interventions in this setting, and provides an outline for family counseling with the goal of

Study population: The database includes all hospital births in Denmark. Main variables: Anesthesia/pain relief, continuous support for women in the delivery room, lacerations (third and fourth degree, cesarean section, postpartum hemorrhage, establishment of skin-to-skin contact between the mother and the newborn infant, severe fetal hypoxia (proportion of live-born children with neonatal hypoxia, delivery of a healthy child after an uncomplicated birth, and anesthesia in case of cesarean section. Descriptive data: Data have been collected since 2010. As of August 2015, data on women and children representing 269,597 births and 274,153 children have been collected. All data for the DNQDB is collected from the Danish Medical Birth Registry. Registration to the Danish Medical Birth Registry is mandatory for all maternity units in Denmark. During the 5 years, performance has improved in the areas covered by the process indicators and for some of the outcome indicators. Conclusion: Measuring quality of care during childbirth has inspired and enabled staff to attend to the quality of the care they provide and has led to improvements in most of the areas covered.

  4. Age, relationship status, and the planning status of births

    Directory of Open Access Journals (Sweden)

    Sarah Hayford

    2010-08-01

    Full Text Available In the United States historically, births to older mothers have been more likely to be planned than births to younger mothers, and births to unmarried women have been less likely to be planned than births to married women. As the average age of mothers has increased and more births have occurred outside of marriage in the United States, the intersection of these trends may have weakened the traditional linkage between age and birth planning status. In this article, we examine differences by maternal age in planning status of births using The 2002 National Survey of Family Growth. We find that age is strongly associated with planning status, but the association is reduced in magnitude when controlling for relationship status and is stronger for first and second births than for higher-parity births. Further, the association between union status and the planning status of births varies by race-ethnicity.

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

    Independent replication is vital for study findings drawn from Electronic Health Records (EHR). This replication study evaluates the relationship between seasonal effects at birth and lifetime cardiovascular condition risk. We performed a Season-wide Association Study on 1,169,599 patients from Mount Sinai Hospital (MSH) to compute phenome-wide associations between birth month and CVD. We then evaluated if seasonal patterns found at MSH matched those reported at Columbia University Medical Center. Coronary arteriosclerosis, essential hypertension, angina, and pre-infarction syndrome passed phenome-wide significance and their seasonal patterns matched those previously reported. Atrial fibrillation, cardiomyopathy, and chronic myocardial ischemia had consistent patterns but were not phenome-wide significant. We confirm that CVD risk peaks for those born in the late winter/early spring among the evaluated patient populations. The replication findings bolster evidence for a seasonal birth month effect in CVD. Further study is required to identify the environmental and developmental mechanisms. PMID:27624541

    Full Text Available Objective. Preterm birth (PTB remains a major cause of neonatal morbidity and mortality. The association between PTB and infection is clear. The purpose of this report is to present a focused review of information on the use of antibiotics to prevent PTB. Methods. We performed a search of the PubMed database restricted to clinical trials or meta-analyses published in English from 1990 through May 2011 using keywords “antibiotics or antimicrobials” and “preterm.” Results. The search yielded 67 abstracts for review. We selected 31 clinical trials (n=26 or meta-analysis (n=5 for further full-text review. Discussion of each eligible clinical trial, its specific inclusion criteria, antibiotic regimen used, and study results are presented. Overall, trials evaluating antibiotic treatment to prevent preterm birth have yielded mixed results regarding any benefit. Conclusion. Routine antibiotic prophylaxis is not recommended for prevention of preterm birth.

    Full Text Available Background: the congenital malformations constitute the first cause of infantile death in developed countries, as well as the second cause of death in Cuba, in younger children of an elderly year. Objective: characterizing the live birth newborns with congenital malformations at Marianao municipality during the year 2011. Methods: descriptive, cross-section study of 30- live birth with congenital malformations at Marianao municipality in Havana, during the year 2011. Some of analyzed variables were: sex, affected system, congenital malformation, type of malformation, severity, birth weight, gestational age, prenatal diagnosis, family history of congenital malformation, maternal age, among others. Results: the masculine sex was the more affected, with 18 cases that represented the 60 %. The Polydactyl was the malformation further frequent, with 23.3 %, followed by the pre-aural appendix, with 10 %. The 20 % was born pre-term and only in the 10 % of the cases was obtained a positive result in the tests of prenatal diagnosis. Conclusions: the live birth with MC were characterized to be males with isolated MC and less severe, full term, normopeso, without family history of the aforementioned affection and with a negative prenatal diagnosis. The majority of mothers belonged to 20-35's age group years, they suffered from hypertension and during pregnancy, the principal diseases that they presented were the sepsis and anemia.

    Full Text Available Background : Magnesium ion gates the N-methyl-D-aspartate (NMDA receptor and may protect the brain from NMDA receptor-mediated asphyxial injury. The present study evaluated the neuroprotective role of magnesium in birth asphyxia. Material and Methods : Forty term neonates with severe birth asphyxia were randomized to either the study group or the control group. Neonates in the study group received magnesium sulfate in a dose of 250 mg/kg initially within half an hour of birth followed by 125 mg/kg at 24 and 48 h of birth. Cranial computed tomography (CT scan and electroencephalography (EEG were performed for all the babies. Denver II was used for developmental assessment at the age of 6 months. Results : Two babies in each group died of severe hypoxic ischemic encephalopathy. EEG abnormalities occurred in 43.75% of the cases in the control group compared with 31.25% in the study group. CT scan abnormalities were present in 62.5% of the control group compared with 37.5% of the cases in the study group. The Denver II assessment at 6 months revealed that there were five babies that were either abnormal or suspect in the control group compared with three in the study group. Conclusion : Magnesium is well tolerated and does appear to have beneficial effects in babies with severe asphyxia. More data is however needed and a large multicenter trial should be conducted.

    2010-01-01

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

  14. Mother's occupation and sex ratio at birth

    2010-05-01

    Full Text Available Abstract Background Many women are working outside of the home, occupying a multitude of jobs with varying degrees of responsibilities and levels of psychological stress. We investigated whether different job types in women are associated with child sex at birth, with the hypothesis that women in job types, which are categorized as "high psychological stress" jobs, would be more likely to give birth to a daughter than a son, as females are less vulnerable to unfavourable conditions during conception, pregnancy and after parturition, and are less costly to carry to term. Methods We investigated the effects of mother's age, maternal and paternal job type (and associated psychological stress levels and paternal income on sex ratio at birth. Our analyses were based on 16,384 incidences of birth from a six-year (2000 to 2005 inclusive childbirth dataset from Addenbrooke's Hospital in Cambridge, UK. We obtained a restricted data set from Addenbrooke's hospital with: maternal age, maternal and paternal occupations, and whether or not the child was first-born. Results Women in job types that were categorized as "high stress" were more likely to give birth to daughters, whereas women in job types that were categorized as "low stress" had equal sex ratios or a slight male bias in offspring. We also investigated whether maternal age, and her partner's income could be associated with reversed offspring sex ratio. We found no association between mother's age, her partner's job stress category or partner income on child sex. However, there was an important interaction between job stress category and partner income in some of the analyses. Partner income appears to attenuate the association between maternal job stress and sex ratios at moderate-income levels, and reverse it at high-income levels. Conclusions To our knowledge this is the first report on the association between women's job type stress categories and offspring sex ratio in humans, and the

  15. The spatial evaluation of neighborhood clusters of birth defects

    Energy Technology Data Exchange (ETDEWEB)

    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.

    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.

  6. Extension of the preceding birth technique.

    Science.gov (United States)

    Aguirre, A

    1994-01-01

    The Brass-inspired Preceding Birth Technique (PBT), is an indirect estimation technique with low costs of administration. PBT involves asking women at a time close to delivery about the survival of the preceding births. The proportion dead is close to the probability of dying between the birth and the second birthday or an index of early childhood mortality (II or Q). Brass and Macrae have determined that II is an estimate of mortality between birth and an age lower than the birth interval or around 4/5 of the birth interval. Hospital and clinic data are likely to include a concentration of women with lower risks of disease because of higher educational levels and socioeconomic status. A simulation of PBT data from the World Fertility Survey for Mexico and Peru found that the proportions of previously dead children were 0.156 in Peru and 0.092 in Mexican home deliveries. Maternity clinic proportions were 0.088 in Peru and 0.066 in Mexico. Use of clinic and hospital data collection underestimated mortality by 32% in Peru and 15% in Mexico. Another alternative was proposed: interviewing women at some other time than delivery. If the interview was during a child/infant intervention after delivery, the subsample would still be subject to a bias, but this problem could be overcome by computing the weighted average of the actual probability of the older child being dead and the conditional probability of the younger child being dead or both younger and older children being dead. Correction factors could be applied using the general standard of the logit life table system of Brass. Calculation of a simple average of the ages of the younger children could provide enough information to help decide which tables to use. Five surveys were selected for testing the factors of dependence between probabilities of death of successive siblings: Bangladesh, Lesotho, Kenya, Ghana, and Guyana. Higher mortality was related to lower dependency factors between the probabilities of death

    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

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

    Full Text Available Introduction The rate of operative birth by Caesarean section is constantly rising. In Kazakhstan, it reaches 27 per cent. Research data confirm that the percentage of successful vaginal births after previous Caesarean section is 50–70 per cent. How safe the induction of vaginal birth after Caesarean (VBAC remains unclear. Methodology The studied techniques of labour induction were amniotomy of the foetal bladder with the vulsellum ramus, intravaginal administration of E1 prostaglandin (Misoprostol, and intravenous infusion of Oxytocin-Richter. The assessment of rediness of parturient canals was conducted by Bishop’s score; the labour course was assessed by a partogram. The effectiveness of labour induction techniques was assessed by the number of administered doses, the time of onset of regular labour, the course of labour and the postpartum period and the presence of complications, and the course of the early neonatal period, which implied the assessment of the child’s condition, described in the newborn development record. The foetus was assessed by medical ultrasound and antenatal and intranatal cardiotocography (CTG. Obtained results were analysed with SAS statistical processing software. Results The overall percentage of successful births with intravaginal administration of Misoprostol was 93 per cent (83 of cases. This percentage was higher than in the amniotomy group (relative risk (RR 11.7 and was similar to the oxytocin group (RR 0.83. Amniotomy was effective in 54 per cent (39 of cases, when it induced regular labour. Intravenous oxytocin infusion was effective in 94 per cent (89 of cases. This percentage was higher than that with amniotomy (RR 12.5. Conclusions The success of vaginal delivery after previous Caesarean section can be achieved in almost 70 per cent of cases. At that, labour induction does not decrease this indicator and remains within population boundaries.

  16. Refractive status at birth: its relation to newborn physical parameters at birth and gestational age.

    Raji Mathew Varghese

    Full Text Available 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

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

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

    The effect of birth order on educational outcome in the Netherlands is reported for two major social classes, manual and non-manual. The rates of school failure (those who attended schools for the mentally retarded and who failed lower school) were studied in a population of some 200,000 young adult Dutch males born between 1944 and 1946 and whose families of origin had from one to six children. The data used were the records of the Dutch military pre-induction examination. Rates of school failure rose both with increased birth order and with increased family-size, with the exception of one-child families. School failure rates for the first, middle-and last-born were examined for the two social classes, with family size controlled. In general, school-failure rates were significantly related to birth-order position. For each family size and in both social classes, the last-born were at greater risk of school failure than were the first-born.

    A brief history of training of traditional birth attendants (TBAs), summary of evidence for effectiveness of TBA training, and consideration of the future role of trained TBAs in an environment that emphasizes transition to skilled birth attendance are provided. Evidence of the effectiveness of TBA training, based on 60 studies and standard meta-analytic procedures, includes moderate-to-large improvements in behaviours of TBAs relating to selected intrapartum and postnatal care practices, small significant increases in women's use of antenatal care and emergency obstetric care, and small significant decreases in perinatal mortality and neonatal mortality due to birth asphyxia and pneumonia. Such findings are consistent with the historical focus of TBA training on extending the reach of primary healthcare and a few programmes that have included home-based management of complications of births and the newborns, such as birth asphyxia and pneumonia. Evidence suggests that, in settings characterized by high mortality and weak health systems, trained TBAs can contribute to the Millennium Development Goal 4--a two-thirds reduction in the rate of mortality of children aged less than 14 years by 2015--through participation in key evidence-based interventions.

    There is much interest in studying evolutionary games in structured populations, in order to understand how cooperation emerges in communities of egoistic agents. In this paper, we consider a new mechanism for cooperation to survive on networks. Agents are designed to reproduce offspring in proportion to their fitness, i.e., the aggregate payoffs they collected in the previous Prisoner's Dilemma game with neighbours. The population then evolves either by an individual giving birth to an offspring that takes over a random neighbour (birth-death process dynamics as the competition for resources already occupied by others) or by an individual constructing one new site from unexploited resources for its offspring (birth process dynamics as the competition for the unexploited resources which induces the extension of system). The underlying interaction network thus evolves and expands simultaneously with the population dynamics. The birth process dynamics is proved to be one new route that favours cooperators, under which cooperators can successfully resist the invasion of defectors in spite of large cost. Furthermore, under this “birth-death & birth” mechanism, the resulting network has a scale-free degree distribution, a small-world property, and hierarchical topology.

    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.

    Objective To describe the temporal trends and spatial patterns of birth defects occurring in Wuxi, a developed region of China. Methods Wavelet analysis was used to decompose the temporal trends of birth defect prevalence based on the birth defect rates over the past 16 years. Birth defect cases with detailed personal and family information were geo-coded and the relative risk in each village was calculated. General G statistic was used to test the spatial property with different scales. Results Wavelet analysis showed an increasing temporal trend of birth defects in this region. Clustering analysis revealed that changes continued in the spatial patterns with different scales. Conclusion Wuxi is confronted with severe challenges to reduce birth defect prevalence. The risk factors are stable and show no change with spatial scale but an increasing temporal trend. Interventions should be focused on villages with a higher prevalence of birth defects.

    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.

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

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

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

  15. Phenomenon of insufficient birth and educational system

    Full Text Available The most important problem of demographic development of Serbia is the fact that individual strivings, aspirations and responses accompanying the process of giving birth to children are not rational from the aspect of the needs of the society. Reproductive norms are low. The society did not even try, via its institutions, to exert influence on the formation of attitude about the desired number of children, or to largely alleviate a number of obstacles to their realization. Facing the consequences of reproductive behavior is a reality and definitely follows in the upcoming time as well. Is there a space for action undertaken by educational system as a part of political response with the aim of rehabilitation of giving birth? It seems that this space exists and that at least two measures impose themselves in that sense. Reduction of individual age at the end of school and population education. Postponing giving birth for later and later age is a very important cause of a very low fertility level in Serbia today. The reform of educational system might influence an earlier entering of parenthood by reducing the individual age at the end of schooling. Population education is imposed as a new direction of population policy, bearing in mind that an individual does not have enough specific knowledge. More or less, the relation between individual behavior and macro-processes is not perceived, the consequences of unsatisfactory population tendencies, slow pace of demographic changes and their postponed effect are not recognized, one does not think about the preservation of national identity, culture and duration.

    Full Text Available Abstract Background Although behavioural dominance of the right hand in humans is likely to be under genetic control, departures from this population norm, i.e. left- or non-right-handedness, are believed to be influenced by environmental factors. Among many such environmental factors including, for example, low birth weight, testosterone level, and maternal age at birth, season of birth has occasionally been investigated. The overall empirical evidence for the season of birth effect is mixed. Methods We have investigated the effect of season of birth in an epidemiologically robust sample of randomly selected young people (n = 977, all born in the same year. A Kolmogorov-Smirnov type statistical test was used to determine season of birth. Results Neither the right-handed nor the non-right-handed groups demonstrated birth asymmetry relative to the normal population birth distribution. There was no between-group difference in the seasonal distribution of birth when comparing the right-handed to the non-right-handed groups. Conclusion The present study failed to provide support for a season of birth effect on atypical lateralisation of handedness in humans.

    Objective Evidence for optimal timing of delivery for some pregnancy complications at late preterm gestation is limited. The purpose of this study was to identify center variation of indicated late preterm births. Study design We performed an analysis of singleton late preterm and term births from a large U.S. retrospective obstetrical cohort. Births associated with spontaneous preterm labor, major congenital anomalies, chorioamnionitis, and emergency cesarean were excluded. We used modified Poisson fixed effects logistic regression with interaction terms to assess center variation of indicated late preterm births associated with four medical/obstetric comorbidities after adjusting for socio-demographics, comorbidities, and hospital/provider characteristics. Results We identified 150,055 births from 16 hospitals; 9,218 were indicated late preterm births. We found wide variation of indicated late preterm births across hospitals. The extent of center variation was greater for births associated with preterm premature rupture of membranes (risk ratio [RR] across sites: 0.45-3.05), hypertensive disorders of pregnancy (RR across sites: 0.36-1.27), and placenta previa/abruption (RR across sites: 0.48-1.82). We found less center variation for births associated with diabetes (RR across sites: 0.65-1.39). Conclusion Practice variation in the management of indicated late preterm deliveries might be a source of preventable late preterm birth.

  18. Cervical mucus properties stratify risk for preterm birth.

    Agatha S Critchfield

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

    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.

    Calculations with a two-dimensional hydrodynamic simulation show that a generic Raleigh-Taylor-like instability occurs in the mantles of nascent neutron stars, that it is possibly violent, and that the standard spherically symmetric models of neutron star birth and supernova explosion may be inadequate. Whether this 'convective' instability is pivotal to the supernova mechanism, pulsar nagnetic fields, or a host of other important issues that attend stellar collapse remains to be seen, but its existence promises to modify all questions concerning this most energetic of astronomical phenomena.

    Everyone knows that Thomas Alva Edison invented the light bulb, Alexander Graham Bell the telephone and that the Otto and Diesel engines were invented by two Germans bearing those names. But who invented the fuel cell? Fuel cells generate electricity with virtually zero pollution by combining gaseous fuels and air. There are different types generally described as high temperature or low temperature fuel cells. Here, Don Prohaska delves into a recently published book: The Birth of the Fuel Cell, by a descendant of one of the fathers of the fuel cell, and sheds new light on the early days of this technology.

To identify its effect, we use a quasi experiment exploiting the differences in the language of the Comstock anti-obscenity statutes approved in the 1800s and early 1900s in the US. Results suggest that banning the sales of oral contraceptive methods has a negative impact on divorce. These findings are robust to alternative specifications and controls for observed (such as female labour force participation, or changes in the e...

    An intron is an extended genomic feature whose function requires multiple constrained positions - donor and acceptor splice sites, a branch point, a polypyrimidine tract and suitable splicing enhancers - that may be distributed over hundreds or thousands of nucleotides. New introns are therefore unlikely to emerge by incremental accumulation of functional sub-elements. Here we demonstrate that a functional intron can be created de novo in a single step by a segmental genomic duplication. This experiment recapitulates in vivo the birth of an intron that arose in the ancestral jawed vertebrate lineage nearly half a billion years ago.

    In 2014, the Dutch Funeral Organization Yarden started with the participatory preparations for a multicultural funeral home. The project aims at a 24/7 service for the super-diverse population of Amsterdam and beyond. This article gives an ethnographic account of Yarden's efforts to capture cultural diversity. It explores how a multicultural gaze creates a power/knowledge dynamic producing new discourses and shaping new layers of significance. The study then turns into arguing that the birth of the multicultural home is, above all, a cultural, collaborative search leaving (counter-discursive) space for creativity, change, and cultural renewal of all actors involved.

  11. Paternity acknowledgment in 2 million birth records from Michigan.

    Directory of Open Access Journals (Sweden)

    Douglas Almond

    Full Text Available Out-of-wedlock childbearing is more common in the U.S. than in other countries and becoming more so. A growing share of such non-marital births identify the father, which can create a legal entitlement to child support. Relatively little is known about individual determinants of the decision to establish paternity, in part because of data limitations. In this paper, we evaluate all birth records in Michigan from 1993 to 2006, which have been merged to the paternity registry. In 2006, 30,231 Michigan children, almost one quarter of all Michigan births, were born to unmarried mothers and had paternity acknowledged. We find that births with paternity acknowledged have worse outcomes along various health and socio-economic dimensions relative to births to married parents, but better outcomes relative to births to unmarried parents without paternity acknowledgement. Furthermore, unmarried men who father sons are significantly more likely to acknowledge paternity than fathers of daughters.

    2004-01-15

    There is evidence that late birth order is associated with some complex disorders. For neural tube defects (NTDs) there is no consensus as to whether first or increased birth order is associated or not. A meta-analysis of published data on NTDs was carried out to ascertain whether there is an increased risk for children first born or of high birth order to have NTDs. All data available with information regarding the frequency of live births and NTDs cases by birth order (1, 2, 3, and 4 or more) were included in the analysis. Effect sizes calculations were performed. Children with higher birth order are more likely to have spina bifida but not anencephaly. This same effect was also seen for all NTDs combined, which probably reflects the association with spina bifida. These results suggest the compilation of anencephaly and spina bifida data can be the explanation for the controversies seen in the literature.

    2013-08-01

    Juvenile delinquency has long been associated with birth order in popular culture. While images of the middle child acting out for attention or the rebellious youngest child readily spring to mind, little research has attempted to explain why. Drawing from Adlerian birth order theory and Sulloway's born-to-rebel hypothesis, I examine the relationship between birth order and a variety of delinquent outcomes during adolescence. Following some recent research on birth order and intelligence, I use new methods that allow for the examination of between-individual and within-family differences to better address the potential spurious relationship. My findings suggest that contrary to popular belief, the relationship between birth order and delinquency is spurious. Specifically, I find that birth order effects on delinquency are spurious and largely products of the analytic methods used in previous tests of the relationship. The implications of this finding are discussed.

  17. HUBBLE CAPTURES THE HEART OF STAR BIRTH

    Science.gov (United States)

    2002-01-01

    NASA Hubble Space Telescope's Wide Field and Planetary Camera 2 (WFPC2) has captured a flurry of star birth near the heart of the barred spiral galaxy NGC 1808. On the left are two images, one superimposed over the other. The black-and-white picture is a ground-based view of the entire galaxy. The color inset image, taken with the Hubble telescope's Wide Field and Planetary Camera 2 (WFPC2), provides a close-up view of the galaxy's center, the hotbed of vigorous star formation. The ground-based image shows that the galaxy has an unusual, warped shape. Most spiral galaxies are flat disks, but this one has curls of dust and gas at its outer spiral arms (upper right-hand corner and lower left-hand corner). This peculiar shape is evidence that NGC 1808 may have had a close interaction with another nearby galaxy, NGC 1792, which is not in the picture Such an interaction could have hurled gas towards the nucleus of NGC 1808, triggering the exceptionally high rate of star birth seen in the WFPC2 inset image. The WFPC2 inset picture is a composite of images using colored filters that isolate red and infrared light as well as light from glowing hydrogen. The red and infrared light (seen as yellow) highlight older stars, while hydrogen (seen as blue) reveals areas of star birth. Colors were assigned to this false-color image to emphasize the vigorous star formation taking place around the galaxy's center. NGC 1808 is called a barred spiral galaxy because of the straight lines of star formation on both sides of the bright nucleus. This star formation may have been triggered by the rotation of the bar, or by matter which is streaming along the bar towards the central region (and feeding the star burst). Filaments of dust are being ejected from the core into a faint halo of stars surrounding the galaxy's disk (towards the upper left corner) by massive stars that have exploded as supernovae in the star burst region. The portion of the galaxy seen in this 'wide-field' image is

    The past two decades in the United States have seen a 24 % rise in spontaneous late preterm delivery (34 to 36 weeks) of unknown etiology. This study tested the hypothesis that fetal growth was identical prior to spontaneous preterm (n=221, median gestational age at birth 35.6 weeks) and term (n=3706) birth among pregnancies followed longitudinally in Santiago, Chile. The hypothesis was not supported: Preterm-delivered fetuses were significantly larger than their term-delivered peers by mid-second trimester in estimated fetal weight, head, limb and abdominal dimensions, and they followed different growth trajectories. Piecewise regression assessed time-specific differences in growth rates at 4-week intervals from 16 weeks. Estimated fetal weight and abdominal circumference growth rates faltered at 20 weeks among the preterm-delivered, only to match and/or exceed their term-delivered peers at 24–28 weeks. After an abrupt decline at 28 weeks attenuating growth rates in all dimensions, fetuses delivered preterm did so at greater population-specific sex and age-adjusted weight than their peers from uncomplicated pregnancies (p<0.01). Growth rates predicted birth timing: one standard score of estimated fetal weight increased the odds ratio for preterm birth from 2.8 prior to 23 weeks, to 3.6 (95% confidence interval, 1.82–7.11, p<0.05) between 23 and 27 weeks. After 27 weeks, increasing size was protective (OR: 0.56, 95% confidence interval, 0.38–0.82, p=0.003). These data document, for the first time, a distinctive fetal growth pattern across gestation preceding spontaneous late preterm birth, identify the importance of mid-gestation for alterations in fetal growth, and add perspective on human fetal biological variability.

    Quasi-birth and death processes with block tridiagonal matrices find many applications in various areas. Neuts gave the necessary and sufficient conditions for the ordinary ergodicity and found an expression of the stationary distribution for a class of quasi-birth and death processes. In this paper we obtain the explicit necessary and sufficient conditions for l-ergodicity and geometric ergodicity for the class of quasi-birth and death processes, and prove that they are not strongly ergodic.

    Swenson, I; Thang, N M

    1993-06-01

    There was absence of any regional differences in parity progressions and length of birth intervals, although urban-rural differences persisted at most birth orders, suggesting that, as in other studies, the urban-rural differentials are the primary source of variations in fertility between different areas of a country. The significantly higher probability of a subsequent birth after birth order 2 in areas with high infant mortality compared to those with low infant mortality suggests that women in the high-risk provinces may be more likely to advance beyond parity 2 and continue on into the advanced parities. The provinces identified as having high infant mortality had also been identified in other studies as the provinces with the highest crude birth rates and population growth rates, the least available family planning services, and highest crude death rates. Mothers' education was consistently related to the likelihood of another birth at each birth order, with the most-educated women experiencing a significantly lower probability of having a subsequent birth at every birth order. This concurs with results in other studies, suggesting that the woman's education is a prime determinant of fertility and that increasing the educational attainment of women is one of the most beneficial measures to reduce fertility. The significant relationship between the previous birth interval of the index child and the probability that the index child would be followed by a subsequent birth conforms with other studies of birth interval dynamics that suggest that pregnancy-spacing for a given woman remains constant throughout her reproductive career.(ABSTRACT TRUNCATED AT 250 WORDS)

    The impact of war on marriage, divorce, and birth rates in the United States from 1933 to 1986 is explored. The author concludes that "the involvement of the nation in military activities was accompanied by a decrease in marriage and birth rates but not by any change in divorce rates. Mobilization of the armed forces and demobilization had no discernible impact on divorce, marriage or birth rates."

    Preterm birth is the principal factor contributing to adverse outcomes in multiple pregnancies. Randomized controlled trials of progestogens to prevent preterm birth in twin pregnancies have shown no clear benefits. However, individual studies have not had sufficient power to evaluate potential b...... benefits in women at particular high risk of early delivery (for example, women with a previous preterm birth or short cervix) or to determine adverse effects for rare outcomes such as intrauterine death....

    Many studies have been undertaken with the purpose of contributing towards the prevention of perineal trauma in normal birth. The objective of this study was to relate height of the perineum, duration of the second stage of labor, variation of the position of the head detaching, kind of effort, presence of the umbilical cord around the babies' neck, birth weight and vulva's ardor to urinate with the occurrence of perineal laceration. The study was undertaken in 2003 at the Normal Birth Center of the Amparo Maternal, with a sample consisting of 67 women in labor without previous vaginal births. The results demonstrated that there were no significant statistical differences between the variables verified.

  7. Seasonality of births: stability and change in a developing country.

    A marked seasonality of births for the two main ethnic groups of peninsular Malaysia, far exceeding the cyclic fluctuations in births in the United States and Canada, was reported for the 1960s. A 36% excess of births over the average monthly number was observed among Malays each January. Among the ethnic Chinese in Malaysia a regular periodicity in the numbers of births was also found, but it was far less marked and the peak occurred in October or November. The peaks in both groups were due in large measure to conceptions that correlate with religious observances or holidays. Here I report on cyclic birth patterns in peninsular Malaysia for the period 1970-1985. Rapid economic development has occurred during this time and has brought with it demographic changes, such as a massive rise in contraceptive use and a decline in birth rates. These demographic changes have been accompanied by the loss of the pronounced seasonal pattern of births among the Malays. The seasonality of Malay births is now of roughly the same magnitude as the seasonality in the United States and Canada, whereas seasonality of births among the Chinese in Malaysia remains essentially unchanged.

    Childbirth is a highly emotive event that can involve complications. Around 1% of births in the United Kingdom involve life-threatening complications to the mother (Waterstone, Bewley, & Wolfe, 2001) and 0.8% result in stillbirth or perinatal death (Confidential Enquiry into Maternal and Child Health [CEMACH], 2009). A review found that 3.1% of women report posttraumatic stress disorder (PTSD) after birth (Grekin & O'Hara, 2014). The aim of this study was to examine whether narrative characteristics of traumatic birth were specific to women with PTSD or observed in all women who experience a highly emotive and potentially traumatic birth. Parturient women were matched for birth events, but either had severe PTSD symptoms (n = 22) or no, or very low, PTSD symptoms (n = 22). Women were interviewed about the birth 3 and 6 months postpartum, and their birth narratives were examined for content, coherence, and cognitive and perceptual processing. Results showed birth narratives became shorter and more coherent over time. Consistent with PTSD literature, birth memories were more likely to be recalled and involuntarily triggered in women with PTSD symptoms. However, women with PTSD symptoms had more coherent narratives, used more causal and fewer tentative words. These latter findings are inconsistent with research finding that PTSD is associated with fragmented or incoherent memories but are consistent with the view that highly emotive events result in improved memory (e.g., Berntsen, Willert, & Rubin, 2003). Possible reasons for this are discussed.

    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

    Preterm birth constitutes a significant international public health issue, with implications for child and family well-being. High levels of psychosocial stress and negative affect before and during pregnancy are contributing factors to shortened gestation and preterm birth. We developed a cumulative psychosocial stress variable and examined its association with early delivery controlling for known preterm birth risk factors and confounding environmental variables. We further examined this association among subgroups of women with different levels of coping resources. Utilizing the All Our Babies (AOB) study, an ongoing prospective pregnancy cohort study in Alberta, Canada (n = 3,021), multinomial logistic regression was adopted to examine the independent effect of cumulative psychosocial stress and preterm birth subgroups compared to term births. Stratified analyses according to categories of perceived social support and optimism were undertaken to examine differential effects among subgroups of women. Cumulative psychosocial stress was a statistically significant risk factor for late preterm birth (OR = 1.73; 95 % CI = 1.07, 2.81), but not for early preterm birth (OR = 2.44; 95 % CI = 0.95, 6.32), controlling for income, history of preterm birth, pregnancy complications, reproductive history, and smoking in pregnancy. Stratified analyses showed that cumulative psychosocial stress was a significant risk factor for preterm birth at psychosocial stress on the risk for early delivery.

    CHINA has achieved remarkable results in birth control since adopting a basic state policy of family planning to control the birth rate and increase the population quality. According to the "1997 Statistic Bulletin for National Economy and Social Development," a document recently issued by the State Statistics Bureau, China maintained a low birth rate of 16.57 per thousand in 1997—a natural population growth of one percent. Women of child-bearing age now average about two births each, a decrease from six in 1970.

    Objectives This study examines the influence of socioeconomic circumstances in childhood (childhood SES) and adulthood (adult SES) on timing of first birth by age 37. Methods A longitudinal study of a 1972–1973 New Zealand birth cohort collected information on socioeconomic characteristics from age 3–32 and reproductive histories at 21, 26, 32 and 38; information on first birth was available from 978 of the original 1037. Relative Risks (RR) and 95% Confidence Intervals (CI) were calculated using Poisson regression to examine first live birth prior to age 21, from 21–25, from 26–31, and from 32–37, by socioeconomic characteristics at different ages. Results Overall, 68.5% of men had fathered a child and 75.9% of women had given birth, by age 37; with overall differences in parenthood to age 31 for men, and 37 for women evident by childhood SES. While parenthood by age 20 was strongly associated with lower childhood SES for both sexes, first entry into motherhood from 32–37 was more likely with higher adult SES at age 32 (RR = 1.8, 95% CI 1.1–3.0 for medium and RR = 1.9, 95% CI 1.1–3.3 for high compared with low). Education also differientated age at parenthood, with those with higher education more likely to defer fatherhood past age 31, and motherhood past age 25 followed by a period of increased likelihood of motherhood for women with higher levels of education from age 32–37 (RR = 1.4, 95% CI 0.87–2.2 and RR = 1.7, 95% CI 1.1–2.6 for medium and high respectively compared with low). Conclusions SES varies across the lifecourse, and SES at the time has the strongest association with first births at that time. Low childhood SES drives adolescent parenthood, with resulting cumulative differences in parenthood past age 30. Those with more education and higher adult SES are deferring parenthood but attempt to catch up in the mid to late thirties. PMID:28085935

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

    Amos Grünebaum

    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]. The difference in neonatal mortality between certified and uncertified midwives at home births did not reach statistical levels (10.0/10,000 births versus 13.7/10,000 births p = 0.2.This study confirms that when compared to midwife-attended hospital births, neonatal mortality rates at home births are significantly increased. While NNM was increased in planned homebirths attended by uncertified midwives when compared to certified midwives, this difference was not statistically significant. Neonatal

  16. Recent increase in sex ratio at birth in Viet Nam.

    Christophe Z Guilmoto

    Full Text Available INTRODUCTION: Since the 1980s, sex ratio at birth (male births per 100 female births has increased in many Asian countries as a result of selective abortions, but to date there has been no such evidence for Viet Nam. Our aim in this paper is to ascertain the situation with respect to sex ratio at birth in Viet Nam over the past five years. MATERIALS AND METHODS: Original data were obtained from sample population surveys in Viet Nam recording annual birth rates since 2000 of about 450,000 women, as well as from two successive birth surveys conducted for the first time in 2007 (1.1 million births. The annual population surveys include specific information on birth history and mothers' characteristics to be used for the analysis of trends and differentials in sex ratio at birth. RESULTS AND DISCUSSION: Birth history statistics indicate that the SRB in Viet Nam has recorded a steady growth since 2001. Starting from a level probably close to the biological standard of 105, the SRB reached 108 in 2005 and 112 in 2006, a value significantly above the normal level. An independent confirmation of these results comes from the surveys of births in health facilities which yielded a SRB of 110 in 2006-07. High SRB is linked to various factors such as access to modern health care, number of prenatal visits, level of higher education and employment status, young age, province of residence and prenatal sex determination. These results suggest that prenatal sex determination followed by selective abortion has recently become more common in Viet Nam. This recent trend is a consequence of various factors such as preference for sons, declining fertility, easy access to abortion, economic development as well as the increased availability of ultrasonography facilities.

    Background In a recent study, high maternal periconceptional intake of vitamin E was found to be associated with risk of congenital heart defects (CHDs). To explore this association further, we investigated the association between total daily vitamin E intake and selected birth defects. Methods We analyzed data from 4,525 controls and 8,665 cases from the 1997–2005 National Birth Defects Prevention Study. We categorized estimated periconceptional energy-adjusted total daily vitamin E intake from diet and supplements into quartiles (referent, lowest quartile). Associations between quartiles of energy-adjusted vitamin E intake and selected birth defects were adjusted for demographic, lifestyle, and nutritional factors. Results We observed a statistically significant association with the third quartile of vitamin E intake (OR 1.17; 95% CI 1.01 – 1.35) and all CHDs combined. Among CHD sub-types, we observed associations with left ventricular outflow tract obstruction defects, and its sub-type, coarctation of the aorta and the third quartile of vitamin E intake. Among defects other than CHDs, we observed associations between anorectal atresia and the third quartile of vitamin E intake (OR 1.66; 95% CI 1.01 – 2.72) and hypospadias and the fourth quartile of vitamin E intake (OR 1.42; 95% CI 1.09 – 1.87). Conclusions Selected quartiles of energy-adjusted estimated total daily vitamin E intake were associated with selected birth defects. However, because these few associations did not exhibit exposure-response patterns consistent with increasing risk associated with increasing intake of vitamin E, further studies are warranted to corroborate our findings.

    Full Text Available Racial disparity in preterm is a major problem in the US. Although significant strides have been made in identifying some of the risk factors, the complexities between community and individual factors are not understood. This study examines the influence of individual and community level factors affecting preterm birth among Black and White women in an urban setting. A 10-year live birth registry dataset from a mid-sized, racially diverse city was analyzed (N = 30,591. Data were geocoded and merged with block group level Census data. Five hierarchical models were examined using PROC GLIMMIX. Education, illicit drug use, pregnancy complications, previous preterm birth, paternal presence, inadequate and adequate plus prenatal care, and poverty were associated with preterm births in both Blacks and Whites. In Black women, increasing maternal age, maternal smoking, and a previous infant death were significant predictors of preterm births, which was not the case for White women. Residing in medium or high poverty neighborhoods resulted in 19% and 28% higher odds, respectively, of preterm birth for Black women. In addition to individual level factors, neighborhood poverty is an important risk factor influencing preterm birth. It is essential to engage multisectoral agencies in addressing factors influencing preterm birth.

    Planned home birth is a paradigmatic case study of the importance of ethics and professionalism in contemporary perinatology. In this article we provide a summary of recent analyses of the Centers for Disease Control database on attendants and birth outcomes in the United States. This summary documents the increased risks of neonatal mortality and morbidity of planned home birth as well as bias in Apgar scoring. We then describe the professional responsibility model of obstetric ethics, which is based on the professional medical ethics of two major figures in the history of medical ethics, Drs. John Gregory of Scotland and Thomas Percival of England. This model emphasizes the identification and careful balancing of the perinatologist's ethical obligations to pregnant, fetal, and neonatal patients. This model stands in sharp contrast to one-dimensional maternal-rights-based reductionist model of obstetric ethics, which is based solely on the pregnant woman's rights. We then identify the implications of the professional responsibility model for the perinatologist's role in directive counseling of women who express an interest in or ask about planned home birth. Perinatologists should explain the evidence of the increased, preventable perinatal risks of planned home birth, recommend against it, and recommend planned hospital birth. Perinatologists have the professional responsibility to create and sustain a strong culture of safety committed to a home-birth-like experience in the hospital. By routinely fulfilling these professional responsibilities perinatologists can help to prevent the documented, increased risks planned home birth.

    Social inequality in adverse birth outcomes has been demonstrated in several countries. The present study examined the separate and joint effects of parental education and work in order to investigate the causal pathways of social class effects on adverse birth outcomes in Korea. The occurrence of low birth weight, preterm births, and intrauterine growth retardation was examined among 7,766,065 births in Korea from 1995 to 2008. The effect of social inequality, as represented by parental education and work, was examined against adverse birth outcomes using multivariate logistic regression after controlling for other covariates. Parental education had the most significant and greatest effect on all three adverse outcomes, followed by parental work and employment, which had lesser effects. For adverse birth outcomes, the gap between educational levels increased steadily in Korea from 1995 to 2008. Throughout the analysis, the effect of maternal manual work on adverse birth outcomes was apparent in the study results. Given this evidence of social inequality in education and employment, social interventions should aim at more in-depth and distal determinants of health.

  13. Prediction and prevention of recurrent spontaneous preterm birth.

    Science.gov (United States)

    Spong, Catherine Y

    2007-08-01

    Rates of preterm birth have continued to rise despite intensive research efforts over the last several decades. A woman who has a spontaneous preterm birth is at high risk for a subsequent preterm birth. Studies have identified clinical, sonographic, and biochemical markers that help to identify the women at highest risk. Determining cervical length and measuring cervicovaginal fibronectin have been proposed as useful tools for evaluating women at risk of preterm birth and may identify those who might benefit from a timely course of antenatal corticosteroids, but effective interventions to prevent preterm birth remain elusive. In the prevention of recurrent spontaneous preterm birth, recent trials have confirmed the use of progesterone beginning in the second trimester as an effective intervention. Optimal management of women with a history of spontaneous preterm birth includes a thorough review of the obstetric, medical, and social history, with attention to potentially reversible causes of preterm birth (eg, smoking cessation, acute infections, strenuous activities), accurate ultrasound dating, consideration of progesterone therapy beginning at 16-20 weeks of gestation, and close surveillance during the pregnancy for evolving findings. Results from the ongoing trials of cerclage as an interventional therapy and omega-3 fatty acid supplementation as a preventive therapy will provide additional knowledge for the optimal management of these high-risk women.

    The rise in the rate of multiple births since the 1980s is due to the effect of advanced maternal age and increased use of assisted reproductive technology (ART). To determine the trends of prevalence in twin births, we studied the data of a population-based birth defects monitoring system during 26 years in Kanagawa Prefecture, Japan. A total of 15,380 twins from 7,690 deliveries were ascertained from 990,978 births in the Kanagawa Birth Defects Monitoring Program (KAMP) during 1981-2008. From the start of KAMP in 1981, the incidence of twin births had been consistently increasing from 57.0 to 98.6 per 10,000 deliveries until 2003, but after this time, the incidence declined to 78.5 in 2007. While the rate of monozygotic twins has been stable (∼40 per 10,000 deliveries) after 1990, that of dizygotic twins increased from 25.3 to 57.3 per 10,000 deliveries until 2002, and recovered to 40.1 in 2007. These results showed the most recent tendency of twin births and indicated that the single embryo transfer method can provide protection and reduction of perinatal risk caused by multiple births.

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

    2015-10-01

    Each year, 15 million babies worldwide are born preterm. Preterm birth is associated with adverse neurodevelopmental outcomes across the life span. Recent registry-based studies suggest that preterm birth is associated with decreased wealth in adulthood, but the mediating mechanisms are unknown. This study investigated whether the relationship between preterm birth and low adult wealth is mediated by poor academic abilities and educational qualifications. Participants were members of two British population-based birth cohorts born in 1958 and 1970, respectively. Results showed that preterm birth was associated with decreased wealth at 42 years of age. This association was mediated by decreased intelligence, reading, and, in particular, mathematics attainment in middle childhood, as well as decreased educational qualifications in young adulthood. Findings were similar in both cohorts, which suggests that these mechanisms may be time invariant. Special educational support in childhood may prevent preterm children from becoming less wealthy as adults.

    2011-08-01

    Using a mixed-methods approach, the understudied population of birth mothers who placed their infants for adoption 12-20 years ago was explored in the context of their romantic relationships. In a semistructured interview, 104 birth mothers answered detailed questions about their romantic relationships and adoption-related experiences. All birth mothers had disclosed the adoption placement to their romantic partners, and most had done so early because they wanted to be truthful about their past. On average, the birth mothers were satisfied with their romantic relationships and almost half did not believe that the adoption had affected it. Regarding contact in the adoption, a majority of the birth mothers' romantic partners (63.5%) were not directly involved in contact with the adoptive family or adopted youth. Implications about how adoption is perceived and processed within intimate relationships are discussed.

  9. Weight at birth and subsequent fecundability: a prospective cohort study.

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

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

    2006-08-01

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

  14. Births per U.S. woman? Depends on race, ethnicity.

    Haub, C

    1993-09-01

    A profile of mothers giving birth is presented for the US for 1990 based on race and ethnicity. Some of the complexities involved in compiling racial and ethnic data are described. The total fertility rate was 2.1 for all American women, 1.1 for Japanese Americans, and 3.2 for Hawaiians and Mexican Americans. The number of births per woman was derived from state birth registration data, which culls data from preadmission hospital forms filled out by the mother. The denominator of the birth rate comes from the number of women in the specified age group as determined by the Census. The problem arises from self-reports themselves. Consistency between recording systems has been improved since 1989 when births were counted based on mother's race and ethnicity. There have been greater percentages of interracial births for which race of both parents were known, and the trend was for 15% of the births for race of the father not to be reported in 1990. The data revealed that in 1990, Mexican Americans and Hawaiians had the highest birth rate of 3.2, which was comparable to developing countries in Latin America. The other Hispanic group was another high fertility group for a developed country. Low fertility was found among Japanese, Chinese, and Cuban Americans. The actual numbers revealed that non-Hispanic whites constitute 2.6 million out of 4.2 million children born in the US. 595,100 were Hispanics, 661,700 were non-Hispanic blacks, 142,000 were Asian or Pacific Islander, and less than 40,000 were American Indian. Teenage pregnancy was considerable among the ethnic populations: nearly 25% of African Americans, and about 20% of American Indians, Puerto Ricans, Hawaiians, and Mexican Americans having births to women under 20 years of age. The birthing patterns were different among minority groups. Hispanic women had early childbearing and continued childbearing throughout the reproductive years. Black and American Indian women tended to complete childbearing early. Asian

    2008-01-01

    It is fair to say that the deepest mystery in our understanding of nature is the birth of our universe. Much of the dilemma over the last decades comes from the extraordinarily small probability that the universe started with the high energy Big Bang as compared to the chance of nucleating any other event. How can Big Bang cosmology be $10^{10^{123}}$ times less likely than nucleating the present cold universe, while accumulating such exquisite agreement with astrophysical data? Why don't we see the other nucleations that, if left to chance, seem to overwhelmingly outnumber us? Here I discuss the point of view that the selection of the initial conditions can be meaningfully addressed only within the framework of the multiverse and that the reason why Big Bang inflation was preferred over other events lies in the quantum dynamics of the landscape of the initial patches. The out-of-equilibrium dynamics selected the 'survivor' universes be born at high energies and the 'terminal' universes at low energies. I bri...

    Objective To investigate genetic etiologies of preterm birth (PTB) in Argentina through evaluation of single-nucleotide polymorphisms (SNP) in candidate genes and population genetic admixture. Study Design Genotyping was performed in 389 families. Maternal, paternal, and fetal effects were studied separately. Mitochondrial DNA (mtDNA) was sequenced in 50 males and 50 females. Y-chromosome anthropological markers were evaluated in 50 males. Results Fetal association with PTB was found in the progesterone receptor (PGR, rs1942836; p= 0.004). Maternal association with PTB was found in small conductance calcium activated potassium channel isoform 3 (KCNN3, rs883319; p= 0.01). Gestational age associated with PTB in PGR rs1942836 at 32 –36 weeks (p= 0.0004). MtDNA sequencing determined 88 individuals had Amerindian consistent haplogroups. Two individuals had Amerindian Y-chromosome consistent haplotypes. Conclusions This study replicates single locus fetal associations with PTB in PGR, maternal association in KCNN3, and demonstrates possible effects for divergent racial admixture on PTB.

  17. There's good news about birth control pills.

    Science.gov (United States)

    1992-10-01

    Some scientists have shown that the oral contraceptive pill can cause breast cancer and heart disease. But no one is really quite sure about the negative side effects of the pill. Experts are sure that the pill can even prevent some forms of cancer. Studies have shown that users will be more protected from cancer of the ovaries than women who do not take the pill. And the protection lasts even after one stops taking the pill. Through the chemical hormones estrogen and progestogen, the pill sends a message to the ovaries not to produce an egg. When a woman is on the pill, her ovaries get a rest. For that reason, there is less chance for problems like cancer to develop. Also, a woman who takes the pill will be more protected from cancer of the endometrium, because the pill causes her to have lighter periods. In addition, with lighter periods, she will probably have less painful periods, too. Taking the pill also will decrease the risk for getting ovary and breast cysts. Pill users have less chance of developing pelvic inflammatory disease (PID), which, if left untreated, can cause damage to the reproductive organs. The best way to ease any concerns about taking the pill is to talk with health care providers about all the issues of birth control pills and other contraception.

    2014-07-01

    We apply and extend Philo (2000)׳s arguments about Foucault׳s Birth of the Clinic as an inspiration for health geography and the study of governance of gays. Philo identified three spaces through which he argued disease is framed: disease tabled, embodied, and institutionalized. These focus attention on the spatialities through which the medical gaze is power-laden. We adopt this framework empirically through an historical geography of an urban public health system engaged with sexually transmitted infections (STIs) in the "homosexual" population of Seattle, Washington in the 1970s. It reveals the interaction of homophobia, heteronormativity and resistances across places typically understudied in queer historical geography. Our findings also extend this framework, however, by revealing other spaces that were important in the urban politics of sexual health: the gay city, the gay doctor, and the gay community. We suggest, therefore, that these and other spaces may be helpful in other health geographies interested in the dynamics of sexuality, governmentality, and urban public health.

    2010-01-01

    The coalescence of a supermassive black hole binary (SMBHB) is thought to be accompanied by an electromagnetic (EM) afterglow, produced by the viscous infall of the surrounding circumbinary gas disk after the merger. It has been proposed that once the merger has been detected in gravitational waves (GWs) by LISA, follow-up EM searches for this afterglow can help identify the EM counterpart of the LISA source. Here we study whether the afterglows may be sufficiently bright and numerous to be detectable in EM surveys alone. The viscous afterglow, which lasts for years to decades for SMBHBs in LISA's sensitivity window, is characterized by rapid increases in both the bolometric luminosity and in the spectral hardness of the source. If quasar activity is triggered by the same major galaxy mergers that produce SMBHBs, then the afterglow could be interpreted as a signature of the birth of a quasar. Using an idealized model for the post-merger viscous spreading of the circumbinary disk and the resulting light curve,...

    The laboring uterus is a complex and dynamic fluid system. Relatively little is known about the fluid properties in this system. However, the two primary fluids of interest, amniotic fluid and vernix caseosa, likely play integral roles in the force transferred to the fetus during the final stages of parturition. This investigation probes the role of fluid in the force transfer during delivery by considering physical models that determine the role of various components of the full system. The first experimental model represents the fetus passing through the birth canal as concentric cylinders with a fluid filled gap. The rigid, inner cylinder moves through the highly flexible outer cylinder at a prescribed velocity. The geometry of the inner cylinder is varied by aspect ratio and length. A total of five different inner geometries are used to fully investigate the parameter space. As the inner cylinder moves through the outer cylinder, strain measurements are taken. These measurements are converted to force measurements as a function of time and position in the outer cylinder. The results of these experiments are compared with numerical results to form a more complete picture of force transfer. This model can be used as the foundation for predicting the force needed to deliver a fetus in the final stages of parturition. Additionally, more complex models, that incorporate uterine contraction forces, are being developed.

    The birth and explosive growth of mobile money in Kenya has provided economists with an opportunity to study the evolution and impact of a new financial system. Mobile money is an innovation that allows individuals to store, send, and receive money on their mobile phone via text message. This system has opened up basic financial services to many who were previously excluded, and has had real and measurable impacts on the ability of households to protect themselves against health risks. Using a unique survey instrument covering nearly 2,300 households over 2008-2010, we first document the lightning-fast adoption of mobile money in Kenya, which was faster than most documented modern technologies in the United States. We then present evidence on how this innovation allows households to respond better to unexpected adverse health events. We find that in the face of these events, users of mobile money are better able to tap into remittances to finance additional health care costs without having to forego necessary expenditures on education, food, and other consumption needs.

  2. The Diversity of Transients from Magnetar Birth

    2015-01-01

    Strongly-magnetized, rapidly-rotating neutron stars are contenders for the central engines of both long-duration gamma-ray bursts (LGRBs) and hydrogen-poor super-luminous supernovae (SLSNe-I). Models for typical (~minute long) LGRBs invoke magnetars with high dipole magnetic fields (Bd > 1e15 G) and short spin-down times, while models for SLSNe-I invoke neutron stars with weaker fields and longer spin-down times of weeks. Here we identify a transition region in the space of Bd and birth period for which a magnetar can power both a long GRB and a luminous SN. In particular, we show that a 2 ms period magnetar with a spin-down time of ~1e4 s can explain the observations of both the ultra-long GRB 111209 and its associated luminous SN2011kl. For magnetars with longer spin down times, we predict even longer duration (~1e6 s) GRBs and brighter supernovae, a correlation that extends to Swift J2058+05 (commonly interpreted as a tidal disruption event). We further show that previous estimates of the maximum rotationa...

    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.

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

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

    Full Text Available Abstract Background A reference range for the birthweight of multiple births neonates is necessary for the assessment for intrauterine growth. Methods Pairs of multiple births were identified by birthplace, the ages of the parents, gestational age, and the year and month of birth. We studied a total of 32,232 livebirth-livebirth pairs of twins, 1894 triplet live births, and 206 quadruplet live births. Results The median birthweight of males, taking gestational age into account, was ca. 0.05 kg–0.1 kg heavier than that of females. Compared to singleton neonates, the median birthweight of twins was ca. 0.15 kg smaller at the gestational age of 34 weeks, increasing to ca. 0.5 kg at 42 weeks of gestation. As for birth order, the mean birthweight of the first-born twin was heavier than that of the second-born. The standard deviation of birthweight was larger for second-born twins. The birthweight of twins from multiparous mothers was greater than those from primiparous mothers. The median birthweight according to gestational age was found to be the greatest in twins, lower in triplets and the lowest in quadruplets. In triplets, the 50th percentile was 0.08 kg heavier in boys than for girls. Conclusion Our results can be used for assessment of birthweight of multiple births in Japan.

    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   Background: Jaundice is one of the most frequent problems observed in newborns. Our purpose was to investigate the incidence and the risk factors on jaundice noted in the first 24 hours after birth.Methods: All newborns observed to have jaundice within the first 24 hours after birth were enrolled prospectively in this study. Laboratory evaluations included blood group typing of mother and newborn, hemoglobin and hematocrit, complete blood count, peripheral blood smear, reticulocyte count, G6PD activity, maternal indirect and neonatal direct Coombs test, and serum total, conjugated, and unconjugated bilirubin. In all cases, gender, birth weight, Apgar scores, gestational age, mode of delivery, birth trauma, cephalhematoma, maternal age, parity, or any siblings with neonatal jaundice were recorded. Data were analyzed using one-way ANOVA, Student's t-, and chi-square tests.Results: Of a total of 2096 newborns delivered in one year, 122 (5.8% developed jaundice within the first 24 hours after birth. Risk factors for hyperbilirubinemia were ABO incompatibility, prematurity, infection, G6PD deficiency, cephalhematoma, asphyxia, and Rh disease. There were no statistically significant relationships between jaundice and maternal age, parity, mode of delivery, neonatal gender or previous siblings with jaundice (p>0.05.Conclusions: Jaundice observed in the initial 24 hours after birth was infrequent, but clinically significant. All newborns should be followed by repeated exams within the first 24 hours after birth and before discharge, especially if the maternal blood group is O.

    Preterm birth is a public health issue of global significance, which may result in mortality during the perinatal period or may lead to major health and financial consequences due to lifelong impacts. Even though several risk factors for preterm birth have been identified, prevention efforts have failed to halt the increasing rates of preterm birth. Epidemiological studies have identified air pollution as an emerging potential risk factor for preterm birth. However, many studies were limited by study design and inadequate exposure assessment. Due to the ubiquitous nature of ambient air pollution and the potential public health significance of any role in causing preterm birth, a novel focus investigating possible causal mechanisms influenced by air pollution is therefore a global health priority. We hypothesize that air pollution may act together with other biological factors to induce systemic inflammation and influence the duration of pregnancy. Evaluation and testing of this hypothesis is currently being conducted in a prospective cohort study in Mexico City and will provide an understanding of the pathways that mediate the effects of air pollution on preterm birth. The important public health implication is that crucial steps in this mechanistic pathway can potentially be acted on early in pregnancy to reduce the risk of preterm birth. PMID:24382337

    Full Text Available Jodie M Dodd, Caroline A CrowtherDiscipline of Obstetrics and Gynaecology, The University of Adelaide, Adelaide, South Australia, AustraliaAbstract: Preterm birth continues to provide an enormous challenge in the delivery of perinatal health care, and is associated with considerable short and long-term health consequences for surviving infants. Progesterone has a role in maintaining pregnancy, by suppression of the calcium–calmodulin–myosin light chain kinase system. Additionally, progesterone has recognized anti-inflammatory properties, raising a possible link between inflammatory processes, alterations in progesterone receptor expression and the onset of preterm labor. Systematic reviews of randomized controlled trials evaluating the use of intramuscular and vaginal progesterone in women considered to be at increased risk of preterm birth have been published, with primary outcomes of perinatal death, preterm birth <34 weeks, and neurodevelopmental handicap in childhood. Eleven randomized controlled trials were included in the systematic review, involving 2714 women and 3452 infants, with results presented according to the reason women were considered to be at increased risk of preterm birth. While there is a potential beneficial effect in the use of progesterone for some women considered to be at increased risk of preterm birth, primarily in the reduction in the risk of preterm birth before 34 weeks gestation, it remains unclear if the observed prolongation of pregnancy translates into improved health outcomes for the infant.Keywords: progesterone, preterm birth, systematic review, randomized trial

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

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

    Full Text Available Abstract Background Two out of three neonatal deaths occur in just 10 countries and Pakistan stands third among them. Maternal mortality is also high with most deaths occurring during labor, birth, and first few hours after birth. Enhanced access and utilization of skilled delivery and emergency obstetric care is the demonstrated strategy in reducing maternal and neonatal mortality. This trial aims to compare reduction in neonate mortality and utilization of available safe birthing and Emergency Obstetric and Neonatal Care services among pregnant mothers receiving ‘structured birth planning’, and/or ‘transport facilitation’ compared to routine care. Methods A pragmatic cluster randomized trial, with qualitative and economic studies, will be conducted in Jhang, Chiniot and Khanewal districts of Punjab, Pakistan, from February 2011 to May 2013. At least 29,295 pregnancies will be registered in the three arms, seven clusters per arm; 1 structured birth planning and travel facilitation, 2 structured birth planning, and 3 control arm. Trial will be conducted through the Lady Health Worker program. Main outcomes are difference in neonatal mortality and service utilization; maternal mortality being the secondary outcome. Cluster level analysis will be done according to intention-to-treat. Discussion A nationwide network of about 100,000 lady health workers is already involved in antenatal and postnatal care of pregnant women. They also act as “gatekeepers” for the child birthing services. This gate keeping role mainly includes counseling and referral for skill birth attendance and travel arrangements for emergency obstetric care (if required. The review of current arrangements and practices show that the care delivery process needs enhancement to include adequate information provision as well as informed “decision” making and planned “action” by the pregnant women. The proposed three-year research is to develop, through national

    Background: Preterm birth is a major perinatal health problem, but factors leading to it are still not completely understood. Objectives: Our goal was to identify the relation between acute increase in ambient air pollution in a few hours before onset of labor and the risk of preterm birth. Methods: We collected registered birth outcome data and hourly ambient air pollution measurements during 2009‒2013 in Brisbane, Australia. Using a time-stratified case-crossover design and conditional logistic regression models with natural cubic splines, we assessed the shape of air pollution-preterm birth curve, after controlling for potential confounders. We also examined the effect modification of other factors. Results: The association between air pollution [nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide (CO)] and preterm birth was nonlinear. Threshold concentrations for the mean of 0‒24 hr NO2, 24‒48 hr SO2, and 24‒48 hr CO before onset of labor were 7.6 parts per billion (ppb), 3.8 ppb, and 162.5 ppb, respectively. Increases in air pollution concentrations above thresholds were associated with increased risks of preterm birth. The odds ratios of preterm birth at the 95th percentile of NO2, SO2, and CO against the thresholds were 1.17 (95% CI: 1.08, 1.27), 1.01 (95% CI: 0.99, 1.04), and 1.18 (95% CI: 1.06, 1.32), respectively. The associations were modified by demographic factors, such as maternal smoking and socioeconomic status. Conclusion: Acute increases in ambient air pollution concentrations above certain levels before onset of labor may stimulate preterm birth. Citation: Li S, Guo Y, Williams G. 2016.

    2012-02-01

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

  16. Cardiac asystole at birth: Is hypovolemic shock the cause?

    A birth involving shoulder dystocia can rapidly deteriorate-from a fetus with a reassuring tracing in the minutes before birth, to a neonate needing aggressive resuscitation. Infants experiencing a traumatic birth involving shoulder dystocia may be severely compromised, even when the preceding labor was uncomplicated. This paper presents two cases in which infants had normal heart beats recorded 5-10min before birth and were born with cardiac asystole following shoulder dystocia. Often, in cases of shoulder dystocia, infants shift blood to the placenta due to the tight compressive squeeze of the body in the birth canal (along with cord compression) and thereby may be born hypovolemic. Our hypothesis is that the occurrence of sudden cardiac asystole at birth is due to extreme hypovolemic shock secondary to the loss of blood. At birth, the sudden release of pressure on the infant's body results in hypoperfusion resulting in low central circulation and blood pressure. Severe hypovolemic shock from these effects leads to sudden cardiac arrest. Immediate cord clamping maintains the hypovolemic state by preventing the physiologic and readily available placental blood from returning to the infant. Loss of this blood initiates an inflammatory response leading to seizures, hypoxic-ischemic encephalopathy, and brain damage or death. Animal studies have shown that human umbilical stem cells injected into a rat's abdomen after induced brain damage, can protect the rat's brain from developing permanent injury. To prevent damage to newborns, the infant must receive the blood volume and stem cells lost at the time of descent and immediate cord clamping. Recommended countermeasures for research include: (1) resuscitation at the perineum with intact cord; or (2) milking the cord before clamping; or (3) autologous transfusion of placenta blood after the birth; or (4) rapid transfusion of O negative blood after birth and before seizures begin.

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

    We further study the kinetic behavior of the exchange-driven growth with birth and death for the case of birth rate kernel being less than that of death based on the mean-field theory. The symmetric exchange rate kernel is K(k,j) = K'(k,j) = Ikjv, and the birth and death rates are proportional to the aggregate's size. The long time asymptotic behavior of the aggregate size distribution ak(t) is found to obey a much unusual scaling law with an exponentially growing scaling function φ(x) = exp(x).

    Many studies in economics use quarter of birth as an instrument for identifying the causal effect of schooling on outcomes such as earnings and health. The key assumption in these studies is that people born in different quarters of the year do not differ systematically in their unobserved abilities. This study uses genetic data from the US Health and Retirement Study to analyze the validity of the quarter of birth instrument. We find some evidence that genetic factors influencing education are not randomly distributed over the year. However, these factors only slightly change the effect of quarter of birth on schooling.

    Information available from birth certificates was used to predict the psychological and educational status of approximately 1,000 randomly sampled first-grade children. The purpose of the research was to explore the feasibility of using birth certificate information as a cost-effective mechanism to identify children who were likely to need special educational services at public school entry. Multiple-regression and discriminant-function analyses revealed the following factors to be important in predicting psychoeducational status: birth order, race, educational status of the mother, month prenatal care began, survivorship of older siblings, and the child's legitimacy.

    1984-12-01

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

    This paper tests whether the strength of the "spring spike" in birth defects is related to agricultural production and urban location using Texas Birth Defects Registry data for the period 1996-2007. We find evidence of a spike in birth defects among children conceived in the spring and summer, but it is more pronounced in urban non-agricultural counties than in other types of counties. Furthermore, the spike lasts longer in urban non-agricultural counties as compared to other types of counties.

    2013-02-01

    Full Text Available Abstract Background Publicly insured women usually have a different demographic background to privately insured women, which is related to poor neonatal outcomes after birth. Given the difference in nature and risk of preterm versus term births, it would be important to compare adverse neonatal outcomes after preterm birth between these groups of women after eliminating the demographic differences between the groups. Methods The study population included 3085 publicly insured and 3380 privately insured, singleton, preterm deliveries (32–36 weeks gestation from Western Australia during 1998–2008. From the study population, 1016 publicly insured women were matched with 1016 privately insured women according to the propensity score of maternal demographic characteristics and pre-existing medical conditions. Neonatal outcomes were compared in the propensity score matched cohorts using conditional log-binomial regression, adjusted for antenatal risk factors. Outcomes included Apgar scores less than 7 at five minutes after birth, time until establishment of unassisted breathing (>1 minute, neonatal resuscitation (endotracheal intubation or external cardiac massage and admission to a neonatal special care unit. Results Compared with infants of privately insured women, infants of publicly insured women were more likely to receive a low Apgar score (ARR = 2.63, 95% CI = 1.06-6.52 and take longer to establish unassisted breathing (ARR = 1.61, 95% CI = 1.25-2.07, yet, they were less likely to be admitted to a special care unit (ARR = 0.84, 95% CI = 0.80-0.87. No significant differences were evident in neonatal resuscitation between the groups (ARR = 1.20, 95% CI = 0.54-2.67. Conclusions The underlying reasons for the lower rate of special care admissions in infants of publicly insured women compared with privately insured women despite the higher rate of low Apgar scores is yet to be determined.

    The dusty disks around young stars make the news regularly due to their appeal as the birthplace of early exoplanets. But how do disks like these first form and evolve around their newly born protostars? New observations from the Atacama Large Millimeter/submillimeter Array (ALMA) are helping us to better understand this process.Formation from CollapseStars are born from the gravitational collapse of a dense cloud of molecular gas. Long before they start fusing hydrogen at their centers when they are still just hot overdensities in the process of contracting we call them protostars. These low-mass cores are hidden at the hearts of the clouds of molecular gas from which they are born.Aerial image of the Atacama Large Millimeter/submillimeter Array. [EFE/Ariel Marinkovic]During this contraction phase, before a protostar transitions to a pre-main-sequence star (which it does by blowing away its outer gas envelope, halting the stars growth), much of the collapsing material will spin into a centrifugally supported Keplerian disk that surrounds the young protostar. Later, these circumstellar disks will become the birthplace for young planets something for which weve seen observational evidence in recent years.But how do these Keplerian disks which eventually have scales of hundreds of AU first form and grow around protostars? We need observations of these disks in their early stages of formation to understand their birth and evolution a challenging prospect, given the obscuring molecular gas that hides them at these stages. ALMA, however, is up to the task: it can peer through to the center of the gas clouds to see the emission from protostellar cores and their surroundings.ALMA observations of the protostar Lupus 3 MMS. The molecular outflows from the protostar are shown in panel a. Panel b shows the continuum emission, which has a compact component that likely traces a disk surrounding the protostar.

    2017-01-01

    In the last two decades, many studies have focused on whether periodontitis is a risk factor for preterm birth (PTB). However, both epidemiological investigation and intervention trials have reached contradictory results from different studies. What explains the different findings, and how should future studies be conducted to better assess this risk factor? This article reviews recent epidemiological, animal, and in vitro studies as well as intervention trials that evaluate the link between periodontitis and PTB. Periodontitis may act as a distant reservoir of microbes and inflammatory mediators and contribute to the induction of PTB. Animal studies revealed that maternal infections with periodontal pathogens increase levels of circulating IL-1β, IL-6, IL-8, IL-17, and TNF-α and induce PTB. In vitro models showed that periodontal pathogens/byproducts induce COX-2, IL-8, IFN-γ, and TNF-α secretion and/or apoptosis in placental tissues/cells. The effectiveness of periodontal treatment to prevent PTB is influenced by the diagnostic criteria of periodontitis, microbial community composition, severity of periodontitis, treatment strategy, treatment efficiency, and the period of treatment during pregnancy. Although intervention trials reported contradictory results, oral health maintenance is an important part of preventive care that is both effective and safe throughout pregnancy and should be supported before and during pregnancy. As contradictory epidemiological and intervention studies continue to be published, two new ideas are proposed here: (1) severe and/or generalized periodontitis promotes PTB and (2) periodontitis only promotes PTB for pregnant women who are young or HIV-infected or have preeclampsia, pre-pregnancy obesity, or susceptible genotypes.

  8. Tracking topic birth and death in LDA.

    Energy Technology Data Exchange (ETDEWEB)

    2011-09-01

    Most topic modeling algorithms that address the evolution of documents over time use the same number of topics at all times. This obscures the common occurrence in the data where new subjects arise and old ones diminish or disappear entirely. We propose an algorithm to model the birth and death of topics within an LDA-like framework. The user selects an initial number of topics, after which new topics are created and retired without further supervision. Our approach also accommodates many of the acceleration and parallelization schemes developed in recent years for standard LDA. In recent years, topic modeling algorithms such as latent semantic analysis (LSA)[17], latent Dirichlet allocation (LDA)[10] and their descendants have offered a powerful way to explore and interrogate corpora far too large for any human to grasp without assistance. Using such algorithms we are able to search for similar documents, model and track the volume of topics over time, search for correlated topics or model them with a hierarchy. Most of these algorithms are intended for use with static corpora where the number of documents and the size of the vocabulary are known in advance. Moreover, almost all current topic modeling algorithms fix the number of topics as one of the input parameters and keep it fixed across the entire corpus. While this is appropriate for static corpora, it becomes a serious handicap when analyzing time-varying data sets where topics come and go as a matter of course. This is doubly true for online algorithms that may not have the option of revising earlier results in light of new data. To be sure, these algorithms will account for changing data one way or another, but without the ability to adapt to structural changes such as entirely new topics they may do so in counterintuitive ways.

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

    Full Text Available The changes occurred over time in the population have effects on the economy, especially the reductions in thebirth rate which may lead to disturbances in the population structure. The relationship between the economic growthand the birth rate in Romania is analysed over an 11-year period, in order to see its intensity. The presentation of theevolution of the gross domestic product and of the birth rate is completed by the calculation of the Spearmancoefficient for determining the intensity of the relationship between the two indicators. The decrease of the birth rate isdetermined, to a modest extent, by the economic growth, with a wide range of factors that influence it. In this situation,the establishment and implementation of a birth rate recovery strategy is highly necessary to reduce the imbalancecreated in the population structure.

    Full Text Available The purpose of this paper is to investigate the influence of the status of women in society over life expectancy at birth. Based on the data of some of the socio-economic variables for 187 countries worldwide, collected by the United Nations within United Nations Development Programme – Human Development Report, we developed a regression model of life expectancy factors. Through empirical testing of the three hypotheses which refer to different aspects of the status of women in society, we found that the employment ratio between women and men has a statistically significant negative impact on life expectancy at birth, which is, at least at first glance, unexpected. At the same time, the number of teenage births per 100 women aged 15–19 as well as gender inequality has a statistically significant negative impact on life expectancy at birth.

  14. Neonatal skeletal fractures. Birth trauma or child abuse?

    Science.gov (United States)

    Cumming, W A

    1979-03-01

    When a fracture is discovered in a newborn infant, it is important to decide whether it occurred at birth or after birth. Calcification around the fracture site gives a useful estimate of the age of the fracture. We reviewed films of 23 patients with fractures resulting from delivery. The fractures occurred at three different sites: the clavicle, the humerus, and the femur. Calcification could be seen as early as seven days after birth and was absent for as long as 11 days after birth. Six of seven femoral fractures occurred in infants with neuromuscular problems. Fracture at an unusual site or absence of calcification after 11 days should alert the radiologist to the possibility of abuse.

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

    Bloomfield, Frank H

    2011-08-21

    The incidence of preterm birth in developed countries is increasing, and in some countries, including the United States, it is almost as high as in developing countries. Demographic changes in women becoming pregnant can account for only a relatively small proportion of the increase. A significant proportion of spontaneous preterm birth continues to be of unknown cause. Experimental data from animal studies suggesting that maternal undernutrition may play a role in spontaneous, noninfectious, preterm birth are supported by observational data in human populations, which support a role for maternal prepregnancy nutritional status in determining gestation length. In addition, intakes or lack of specific nutrients during pregnancy may influence gestation length and thus the risk of preterm birth. As yet, the role of paternal nutrition in contributing to gestation length is unexplored.

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

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

    Radek Bukowski

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

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

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

    2015-11-17

    This study examined the long-standing question of whether a person's position among siblings has a lasting impact on that person's life course. Empirical research on the relation between birth order and intelligence has convincingly documented that performances on psychometric intelligence tests decline slightly from firstborns to later-borns. By contrast, the search for birth-order effects on personality has not yet resulted in conclusive findings. We used data from three large national panels from the United States (n = 5,240), Great Britain (n = 4,489), and Germany (n = 10,457) to resolve this open research question. This database allowed us to identify even very small effects of birth order on personality with sufficiently high statistical power and to investigate whether effects emerge across different samples. We furthermore used two different analytical strategies by comparing siblings with different birth-order positions (i) within the same family (within-family design) and (ii) between different families (between-family design). In our analyses, we confirmed the expected birth-order effect on intelligence. We also observed a significant decline of a 10th of a SD in self-reported intellect with increasing birth-order position, and this effect persisted after controlling for objectively measured intelligence. Most important, however, we consistently found no birth-order effects on extraversion, emotional stability, agreeableness, conscientiousness, or imagination. On the basis of the high statistical power and the consistent results across samples and analytical designs, we must conclude that birth order does not have a lasting effect on broad personality traits outside of the intellectual domain.

    BACKGROUND Associations have been reported between maternal radiation exposure and birth defects. No such studies were found on radon. Our objective was to determine if there is an association between living in areas with higher radon levels and birth defects. METHODS The Texas Birth Defects Registry provided data on all birth defects from 1999–2009 from the entire state. Mean radon levels by geologic region came from the Texas Indoor Radon Survey. The association between radon and birth defects was estimated using multilevel mixed effect Poisson regression. RESULTS Birth defects overall were not associated with residential radon levels. Of the 100 other birth defect groups with at least 500 cases, 14 were significantly elevated in areas with high mean radon level in crude analyses, and 9 after adjustment for confounders. Cleft lip with/without cleft palate had an adjusted prevalence ratio (aPR) of 1.16 per 1 picoCurie/liter (pCi/l) increase in exposure to region mean radon, 95% confidence interval (CI) 1.08, 1.26. Cystic hygroma / lymphangioma had an aPR of 1.22 per 1 pCi/l increase, 95% CI 1.02, 1.46. Other associations were suggested but not as consistent: three skeletal defects, Down syndrome, other specified anomalies of the brain, and other specified anomalies of the bladder and urethra. CONCLUSIONS In the first study of residential radon and birth defects, we found associations with cleft lip w/wo cleft palate and cystic hygroma / lymphangioma. Other associations were suggested. The ecological nature of this study and multiple comparisons suggest that our results be interpreted with caution. PMID:25846606

    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.

    This article draws on qualitative data to explore the beliefs through which decisions about caesarean birth are made and to consider how these might contribute to the increasing rate of caesarean birth. A total of 36 interviews were conducted in Australia, including 12 hospital-based midwives, 6 obstetricians, and 18 women who had experienced caesarean birth within the 2 years prior to the research interview. Data reveal a belief derived from the pervasive discourse of neo-liberalism that women are self-governing autonomous subjects in their birth experience, with entitlement to the consumption of birthing information and services, as guided by obstetricians. Feeding into this belief are coexisting discourses that serve to organise 'free choice' in terms of safe/unsafe, order/disorder, life/death; and with ontological meanings, by structuring women's mothering identities as good/bad. The neo-liberal obligation to manage risk and pursue success for both mothers and babies means that women (and others) are obliged to choose what is set up as the most obvious and sensible option: safe, ordered caesareans. The structuring of discourses in this way shows how caesareans can be positioned as a preferential means of birth.

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

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

    Half of unmarried births are to women who are already mothers, and a quarter to women who were previously married. We develop a model of equilibrium matching and fertility to replicate these facts. We use the model to revisit the hypothesis that liberalization of the Pill and abortion caused the massive increase since 1960 in the share of US births to unmarried women. Our results suggest that liberalization alone is ineffective; what matters are interactions between liberalization and the dec...

    2010-01-01

    A Web-based survey focusing on geocoding of birth defects data was developed and administrated to gain an understanding of the capacity of state birth defects programs to geocode maternal residence and to identify barriers to geocoding birth defects data. The survey consisted of 21 questions related to geocoding of maternal residence, type of software used, barriers to geocoding, and data linkage. In August 2007, an e-mail with a Web link to the survey was sent to all state birth defects program contacts in the United States, including the District of Columbia, Puerto Rico, and the Centers for Disease Control and Prevention (CDC) requesting they complete the online survey. By October 2007, 39 (74%) out of 53 birth defects program contacts completed the survey. Although nearly all birth defects programs collect maternal residential data, many are not currently geocoding that data. Results indicated that 97% of the programs that completed the survey reported they collected data on maternal residence, 53% of which reported that the birth defects surveillance data were geocoded to the street address level using maternal residential address at delivery. Twenty six percent of the programs that do not currently geocode the data identified "Software and address reference file are not available" as the most significant barrier to geocoding; another 16% chose "Lack of funding" as the most significant barrier to geocoding. Since geocoding is an important component of spatial analyses used to detect potential clusters of birth defects, leveraging resources to overcome the barriers that prevent programs from geocoding is important.

    Young, Kate; Miller, Yvette D

    2015-01-01

    Information in the popular media tends to be biased toward promoting the benefits of medicalized birth for low-risk pregnancies. We aimed to assess the effect of communicating the benefits of non-medicalized birth in magazine articles on women's birth intentions and to identify the mechanisms by which social communication messages affected women's intentions for birth. A convenience sample of 180 nulliparous Australian women aged 18-35 years were randomly exposed to a magazine article endorsing non-medicalized birth (using either celebrity or non-celebrity endorsement) or organic eating (control) throughout June-July 2011. Magazine articles that endorsed non-medicalized birth targeted perceived risk of birth, expectations for labor and birth, and attitudes toward birth. These variables and intention for birth were assessed by self-report before and after exposure. Exposure to a magazine article that endorsed non-medicalized birth significantly reduced women's intentions for a medicalized birth, regardless of whether the endorsement was by celebrities or non-celebrities. Changes in perceived risk of birth mediated the effect of magazine article exposure on women's intentions for a medicalized birth. Persuasive communication that endorses non-medicalized birth could be delivered at the population level and may reduce women's intentions for a medicalized birth.

  7. Obstetric Care Consensus No. 4 Summary: Periviable Birth.

    Science.gov (United States)

    2016-06-01

    Approximately 0.5% of all births occur before the third trimester of pregnancy, and these very early deliveries result in the majority of neonatal deaths and more than 40% of infant deaths. A recent executive summary of proceedings from a joint workshop defined periviable birth as delivery occurring from 20 0/7 weeks to 25 6/7 weeks of gestation. When delivery is anticipated near the limit of viability, families and health care teams are faced with complex and ethically challenging decisions. Multiple factors have been found to be associated with short-term and long-term outcomes of periviable births in addition to gestational age at birth. These include, but are not limited to, nonmodifiable factors (eg, fetal sex, weight, plurality), potentially modifiable antepartum and intrapartum factors (eg, location of delivery, intent to intervene by cesarean delivery or induction for delivery, administration of antenatal corticosteroids and magnesium sulfate), and postnatal management (eg, starting or withholding and continuing or withdrawing intensive care after birth). Antepartum and intrapartum management options vary depending upon the specific circumstances but may include short-term tocolytic therapy for preterm labor to allow time for administration of antenatal steroids, antibiotics to prolong latency after preterm premature rupture of membranes or for intrapartum group B streptococci prophylaxis, and delivery, including cesarean delivery, for concern regarding fetal well-being or fetal malpresentation. Whenever possible, periviable births for which maternal or neonatal intervention is planned should occur in centers that offer expertise in maternal and neonatal care and the needed infrastructure, including intensive care units, to support such services. This document describes newborn outcomes after periviable birth, provides current evidence and recommendations regarding interventions in this setting, and provides an outline for family counseling with the goal of

    Directory of Open Access Journals (Sweden)

    Paul Haggarty

    Full Text Available BACKGROUND: Birth weight and prematurity are important obstetric outcomes linked to lifelong health. We studied a large birth cohort to look for evidence of epigenetic involvement in birth outcomes. METHODS: We investigated the association between birth weight, length, placental weight and duration of gestation and four candidate variants in 1,236 mothers and 1,073 newborns; DNMT1 (rs2162560, DNMT3A (rs734693, DNMT3B (rs2424913 and DNMT3L (rs7354779. We measured methylation of LINE1 and the imprinted genes, PEG3, SNRPN, and IGF2, in cord blood. RESULTS: The minor DNMT3L allele in the baby was associated with higher birth weight (+54 95% CI 10,99 g; p = 0.016, birth length (+0.23 95% CI 0.04,0.42 cm; p = 0.017, placental weight, (+18 95% CI 3,33 g; p = 0.017, and reduced risk of being in the lowest birth weight decile (p = 0.018 or requiring neonatal care (p = 0.039. The DNMT3B minor allele in the mother was associated with an increased risk of prematurity (p = 0.001. Placental size was related to PEG3 (p<0.001 and IGF2 (p<0.001 methylation. Birth weight was related to LINE1 and IGF2 methylation but only at p = 0.052. The risk of requiring neonatal treatment was related to LINE1 (p = 0.010 and SNRPN (p = 0.001 methylation. PEG3 methylation was influenced by baby DNMT3A genotype (p = 0.012 and LINE1 by baby 3B genotype (p = 0.044. Maternal DNMT3L genotype was related to IGF2 methylation in the cord blood but this effect was only seen in carriers of the minor frequency allele (p = 0.050. CONCLUSIONS: The results here suggest that epigenetic processes are linked birth outcome and health in early life. Our emerging understanding of the role of epigenetics in health and biological function across the lifecourse suggests that these early epigenetic events could have longer term implications.

    The low school attainment, early marriage, and low age at first birth of females are major policy concerns in less developed countries. This study jointly estimated the determinants of educational attainment, marriage age, and age at first birth among females aged 12-25 in Madagascar, explicitly accounting for the endogeneities that arose from modelling these related outcomes simultaneously. An additional year of schooling results in a delay to marriage of 1.5 years and marrying 1 year later delays age at first birth by 0.5 years. Parents' education and wealth also have important effects on schooling, marriage, and age at first birth, with a woman's first birth being delayed by 0.75 years if her mother had 4 additional years of schooling. Overall, our results provide rigorous evidence for the critical role of education-both individual women's own and that of their parents-in delaying the marriage and fertility of young women.

    Background The aim of this retrospective study was to explore the relationship between psychotropic medication dosage and birth outcomes. Methods A total of 136 women were enrolled, who had an active mental disorder, were taking medication to prevent a relapse, or had a history of postpartum depression or psychosis. Medication use was evaluated for the three trimesters and during labor. Based on the defined daily dose, medication use was classified into three groups. Primary outcome variables included the infant gestational age at birth, birth weight, and Apgar scores at one and 5 minutes. Results Our study showed a significantly higher incidence of Apgar score ≤7 at 5 minutes in women taking psychotropic drugs as compared with the group taking no medication, respectively (16.3% versus 0.0%, P=0.01). There was no significant difference between the two groups in Apgar score at one minute or in gestational age and birth weight. The results showed no significant differences in gestational age, birth weight, or Apgar scores for a low–intermediate or high dose of a selective serotonin reuptake inhibitor and for a low or intermediate dose of an antipsychotic. Conclusion This study does not indicate a relationship between doses of selective serotonin reuptake inhibitors and antipsychotics and adverse neonatal outcomes. PMID:24376355

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

  14. Technologies of birth and models of midwifery care

    Directory of Open Access Journals (Sweden)

    Christine McCourt

    2014-08-01

    Full Text Available This article is based on a study of a reform in the organisation of maternity services in the United Kingdom, which aimed towards developing a more woman-centred model of care. After decades of fragmentation and depersonalisation of care, associated with the shift of birth to a hospital setting, pressure by midwives and mothers prompted government review and a relatively radical turnaround in policy. However, the emergent model of care has been profoundly influenced by concepts and technologies of monitoring. The use of such technologies as ultrasound scans, electronic foetal monitoring and oxytocic augmentation of labour, generally supported by epidural anaesthesia for pain relief, have accompanied the development of a particular ecological model of birth – often called active management –, which is oriented towards the idea of an obstetric norm. Drawing on analysis of women’s narrative accounts of labour and birth, this article discusses the impact on women’s embodiment in birth, and the sources of information they use about the status of their own bodies, their labour and that of the child. It also illustrates how the impact on women’s experiences of birth may be mediated by a relational model of support, through the provision of caseload midwifery care.

  15. Birth order and selected work-related personality variables.

    Phillips, A S; Bedeian, A G; Mossholder, K W; Touliatos, J

    1988-12-01

    A possible link between birth order and various individual characteristics (e. g., intelligence, potential eminence, need for achievement, sociability) has been suggested by personality theorists such as Adler for over a century. The present study examines whether birth order is associated with selected personality variables that may be related to various work outcomes. 3 of 7 hypotheses were supported and the effect sizes for these were small. Firstborns scored significantly higher than later borns on measures of dominance, good impression, and achievement via conformity. No differences between firstborns and later borns were found in managerial potential, work orientation, achievement via independence, and sociability. The study's sample consisted of 835 public, government, and industrial accountants responding to a national US survey of accounting professionals. The nature of the sample may have been partially responsible for the results obtained. Its homogeneity may have caused any birth order effects to wash out. It can be argued that successful membership in the accountancy profession requires internalization of a set of prescribed rules and standards. It may be that accountants as a group are locked in to a behavioral framework. Any differentiation would result from spurious interpersonal differences, not from predictable birth-order related characteristics. A final interpretation is that birth order effects are nonexistent or statistical artifacts. Given the present data and particularistic sample, however, the authors have insufficient information from which to draw such a conclusion.

    Full Text Available Abstract Background The children of teen mothers have been reported to have higher rates of several unfavorable mental health outcomes. Past research suggests several possible mechanisms for an association between religiosity and teen birth rate in communities. Methods The present study compiled publicly accessible data on birth rates, conservative religious beliefs, income, and abortion rates in the U.S., aggregated at the state level. Data on teen birth rates and abortion originated from the Center for Disease Control; on income, from the U.S. Bureau of the Census, and on religious beliefs, from the U.S. Religious Landscape Survey carried out by the Pew Forum on Religion and Public Life. We computed correlations and partial correlations. Results Increased religiosity in residents of states in the U.S. strongly predicted a higher teen birth rate, with r = 0.73 (p Conclusion With data aggregated at the state level, conservative religious beliefs strongly predict U.S. teen birth rates, in a relationship that does not appear to be the result of confounding by income or abortion rates. One possible explanation for this relationship is that teens in more religious communities may be less likely to use contraception.

  17. Birth defects in India: Hidden truth, need for urgent attention

    2013-01-01

    Indian people are living in the midst of risk factors for birth defects, e.g., universality of marriage, high fertility, large number of unplanned pregnancies, poor coverage of antenatal care, poor maternal nutritional status, high consanguineous marriages rate, and high carrier rate for hemoglobinopathies. India being the second most populous country with a large number infant born annually with birth defects should focus its attention on strategies for control of birth defects. Many population based strategies such as iodization, double fortification of salt, flour fortification with multivitamins, folic acid supplementation, periconceptional care, carrier screening and prenatal screening are some of proven strategies for control of birth defects. Strategies such as iodization of salt in spite of being initiated for a long time in the past do have a very little impact on its consumption (only 50% were using iodized salt. Community genetic services for control of birth defects can be easily flourished and integrated with primary health care in India because of its well established infrastructure and personnel in the field of maternal and child health care. As there is wide variation for infant mortality rate (IMR in different states in India, so there is a need of deferential approach to implement community genetic services in states those had already achieved national goal of IMR. On the other hand, states those have not achieved the national goal on IMR priority should be given to management of other causes of infant mortality.

Objective: This study analyzes the socioeconomic status (SES of teen, young adult, and older adult mothers across four five-year birth cohorts from 1956 to 1975 who were teens from 1971 to 1994. Methods: Data were pooled from the 1995, 2002, and 2006-2010 National Survey of Family Growth (NSFG. Mothers were categorized by age at first birth and by their birth cohorts. The SES (education, single motherhood, poverty, employment of teen, young adult, and older mothers was compared across cohorts and within cohorts. Results: Among teen mothers, the odds of fulltime employment improved across birth cohorts and the odds of educational attainment beyond high school did not vary. Their odds of single motherhood and living in poverty increased across cohorts. The odds of higher education and single motherhood increased across birth cohorts for young adult mothers as did the odds of living in poverty, even if working fulltime. Among older adult mothers, educational attainment and the odds of single motherhood rose for recent cohorts. Conclusions: Comparisons between teen mothers and both young adult and all adult mothers within cohorts suggest that gaps in single motherhood and poverty between teen and adult mothers have widened over time, to the detriment of teen mothers. Teen mothers have become more likely to be single and poor than in the past and compared to older mothers.

    2011-10-01

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

    We present a new sample of mid L to mid T dwarfs with effective temperatures of 1100 to 1700K selected from the UKIDSS Large Area Survey and confirmed with infrared spectra from X-Shooter/VLT. This effective temperature range is especially sensitive to the formation history of Galactic brown dwarfs and allows us to constrain the form of the sub-stellar birth rate, with sensitivity to differentiate between a flat (stellar like) birth rate, and an exponentially declining form. We present the discovery of 63 new L and T dwarfs from the UKIDSS LAS DR7, including the identification of 12 likely unresolved binaries, which form the first complete sub-set from our program, covering 495 sq degrees of sky, complete to J=18.1. We compare our results for this sub-sample with simulations of differing birth rates for objects of mass 0.10-0.03Msol and ages 1-10Gyrs. We find that the more extreme birth rates (e.g. a halo type form) can likely be excluded as the true form of the birth rate. In addition we find that although t...

    Limited English proficiency is associated with disparities across diverse health outcomes. However, evidence regarding adverse birth outcomes across languages is limited, particularly among U.S. Asian and Pacific Islander populations. The study goal was to consider the relationship of maternal language to birth outcomes using statewide hospitalization data. Detailed discharge data from Hawaii childbirth hospitalizations from 2012 (n = 11,419) were compared by maternal language (English language or not) for adverse outcomes using descriptive and multivariable log-binomial regression models, controlling for race/ethnicity, age group, and payer. Ten percent of mothers spoke a language other than English; 93% of these spoke an Asian or Pacific Islander language. In multivariable models, compared to English speakers, non-English speakers had significantly higher risk (adjusted relative risk [ARR]: 2.02; 95% confidence interval [CI]: 1.34-3.04) of obstetric trauma in vaginal deliveries without instrumentation. Some significant variation was seen by language for other birth outcomes, including an increased rate of primary Caesarean sections and vaginal births after Caesarean, among non-English speakers. Non-English speakers had approximately two times higher risk of having an obstetric trauma during a vaginal birth when other factors, including race/ethnicity, were controlled. Non-English speakers also had higher rates of potentially high-risk deliveries.

    Birth under water has become a widely disseminated technique that is promoted to improve the quality of labor. The case of a 42-week gestation male infant is reported who died of respiratory and multiorgan failure secondary to florid pneumonia and sepsis due Pseudomonas aeruginosa following a water birth. Other infants who have been delivered underwater have drowned or have had near-drowning episodes with significant hyponatremia and water intoxication. Local and disseminated sepsis has been reported, with respiratory distress, fevers, hypoxic brain damage, and seizures. There have also been episodes of cord rupture with hemorrhage. The postmortem investigation of such cases requires a complete autopsy of the infant, with examination of the placenta. Full details of the pregnancy and delivery and inspection of the birthing unit are also needed. A septic workup of the infant and placenta should be undertaken along with sampling of water from the birthing unit and microbiological swabbing of the equipment. Vitreous sodium levels may reveal electrolyte disturbances. While fatal cases appear rare, this may change if water births gain in popularity.

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

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

    Full Text Available Objectives. The objective of this study was to describe first-time mothers’ experiences and reflections of their first birth. Study Design. This study is a part of a larger study which was carried out in southwestern Sweden in 2008. A qualitative method with content analysis was chosen for this study. The unit of data was 14 written narratives from the first-time mothers. Results. The theme “To be empowered increases first-time mothers’ chances for a positive birth experience” crossed over into all the three categories: “To trust the body and to face the pain,” “Interaction between body and mind in giving birth,” and “Consistency of support.” Conclusion. In order to feel confident in their first childbirth, the women wanted to be confirmed and seen as unique individuals by the professionals and their partner. If professionals responded to the individual woman’s needs of support, the woman more often had a positive birth experience, even if the birth was protracted or with medical complications.

    Adolescent childbearing adversely affects both mothers and infants. The birth rate for US adolescent women of Hispanic origin is higher than that for US adolescents overall. Birth rates among US Hispanic adolescents in the border region are higher than rates among other US Hispanic adolescents, and rates among Mexican border adolescents are higher than rates among other Mexican adolescents. We used binational birth certificate data for US Hispanic and Mexican adolescent women living inside the border region, elsewhere within the border states, and in the US and Mexico overall to compare birth rates and other health indicators among these groups. From 2000 to 2009, birth rates for 15-19 year-olds declined 19-28 % among US Hispanic geographic subgroups and 8-13 % among Mexican geographic subgroups; rates in the border region in 2009 were 73.8/1,000 women ages 15-19 for US Hispanics and 87.2/1,000 for Mexicans and were higher than rates in other US and Mexican subgroups, respectively. Less than one in five US Hispanic and Mexican adolescent mothers in the border region was married. About one in three delivered by cesarean. Late or no prenatal care was more prevalent among US Hispanic (17.6 %) than Mexican (14.3 %) border adolescents. Birth weight and gestational age outcomes were generally poorest in Texas border counties compared with border counties in other US states and in municipios of Mexican states bordering Texas. High birth rates and low prenatal care utilization among adolescents are problems along the US-Mexico border.

    2014-12-01

    Full Text Available Background: There is a lack of population-based studies on multiple births and maternal mental health. Having a high-risk pregnancy by bearing two or more children is a stressful life event, and the challenges of parenting two or more children probably also lead to a high level of parental stress. There are a few results on multiple births and maternal mental health from studies on in vitro fertilization samples. The only previous cohort study on multiple birth and maternal mental health included a single measure of depressive symptoms at 9 months postpartum. We aim to estimate the relative risk for depression and anxiety after multiple birth in a population-based prospective cohort study while adjusting for factors prior and subsequent to fertilization.Methods: We used data from 87,807 pregnancies included in the Norwegian Mother and Child Cohort study. Information on multiple birth was retrieved from the Norwegian Medical Birth Registry, and maternal mental health was assessed at 17th and 30th week of gestation and 0.5, 1.5, 3, and 5 years postpartum. There were 1,842 plural births included in the study (i.e. 1,821 twin births and 21 higher order births. We predicted maternal mental health at each time point, subsequently adjusting for 1 factors prior to fertilization (e.g. maternal age and in vitro fertilization; 2 factors during pregnancy (e.g. hypertensive states; 3 factors at delivery (e.g. cesarean section; 4 child-related postnatal complications (e.g. intracranial hemorrhage; and 5 concurrent depression or anxiety after pregnancy.Results: Adjusted for antecedents of plural birth, mothers expecting a plural birth had a normal risk for anxiety (RR=1.05; 95% CI 0.92-1.20 and depression (RR=1.02; 95% CI 0.89-1.16 at 17th week of gestation. However, plural birth was associated with maternal depression at 1.5, 3, and 5 years postpartum and maternal anxiety at 3 years postpartum. The trend was for the association to increase across time, and

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

    1991-04-01

    Although a multitude of differently motivated explanations have been brought forth in connection with legendary and pictorial representations of unusual--mostly extragenital-birth, an attempt is made to demonstrate certain common features by means of numerous examples. A hero or a god was not supposed to be born naturally ("naturally" being synonymous with "unclean", "contaminated"); his birth had to take place in an extravagant manner and was thus an attribute of immortality. Proof of this, for example, is the creation of Adam and Eve in Genesis. Special attention is given to the biphasic character of creation of life: 1. the lifeless figure, and 2. the act of animation, of coming to life. A large variety of comparisons from legends, myths and tales are exemplified by means of illustrations, such as e.g. the birth of the Buddha, Mithras, Athena, Dionysos, Adonis etc.

    2006-01-01

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

  11. Nearby Galaxy is a Hotbed of Star Birth Activity

    2004-01-01

    This new image taken with NASA's Hubble Space Telescope (HST) is of the nearby dwarf galaxy NGC 1569. This galaxy is a hotbed of vigorous star birth activity which blows huge bubbles that riddle its main body. The bubble structure is sculpted by the galactic super-winds and outflows caused by a colossal input of energy from collective supernova explosions that are linked with a massive episode of star birth. The bubbles seen in this image are made of hydrogen gas that glows when hit by the fierce wind and radiation from hot young stars and is racked by supernova shocks. Its 'star factories' are also manufacturing brilliant blue star clusters. NGC 1569 had a sudden onset of star birth about 25 million years ago, which subsided about the time the very earliest human ancestors appeared on Earth. The Marshall Space Flight Center had responsibility for the design, development, and construction of the HST.

    for time to detection of cryptorchidism. Parental employment in the calendar year preceding birth was grouped into one of five socio-occupational classes. Geographical region was defined by place of birth in one of 15 Danish counties. Detection rate ratios of cryptorchidism were analyzed as a function......BACKGROUND: Cryptorchidism (undescended testes) is associated with poor male fertility, but can be alleviated and fertility preserved to some degree by early detection and treatment. Here we assess the influence of socio-occupational class, geographical region, maternal age and birth cohort on time...... but differed slightly between geographical regions. A similar pattern was obtained for surgical correction after a diagnosis. Age at diagnosis decreased by 2.7 years from the early to the late cohort. CONCLUSIONS: These results indicate that childhood socio-occupational inequality in detection and correction...

    2015-09-01

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

    Methodology: This was the cross sectional study conducted in the tertiary care centre of Ahmedabad on the full term babies with birth asphyxia. The maternal, fetal and newborn correlates were recorded according to predesigned proforma. Results: There were total 401 (6.6% babies born with apgar score of less than 7 at one minute and among them, 320 (79.8% were full term babies and 81 (20.2% were preterm babies. Among the babies 52.5% were male, 56.9% were primigravida, and only 41.9% had antenatal care present, 42.2% had MSL and 47.2% were small for date babies. Conclusion: Birth asphyxia is common the babies of the mother who had not received proper antenatal care. Maternal anaemia, primipara, meconium stained liquor babies have more chances of getting birth asphyxia. [Natl J Med Res 2013; 3(4.000: 374-376

    Full Text Available Objective: to analyze the scientific production about the role of the man as a caregiver during the birth process of his partner. Methods: integrative review held in electronic databases Scopus, Cumulative Index to Nursing and Allied Health Literature, PubMed, ISI Web of Knowledge, and Latin American and Caribbean in Health Sciences. Results: there were 389 scientific articles located, of which 26 studies were selected that showed active roles - physical and emotional support - and passive roles – spectator or total lack of viewer participation – of the partner during the birth process. The monitoring of this event by the father is considered positive experience. However, the lack of incentive limits their active participation. Conclusion: despite the historical, religious, cultural, institutional or individual barriers, there is a desire to actively participating in the child´s birth, even though sometimes parents are unprepared to provide the support they would like.

  17. Promotion of birth spacing on Idjwi Island, Zaire.

    1983-05-01

    Idjwi Island in Lake Kivu in eastern Zaire supports approximately 50,000 largely subsistence farmers, the Bani-Iju. Rapid population growth, a declining economy, and a deteriorating environment have already converged to produce significant malnutrition in this isolated community. The highly structured and traditional social order, particularly regarding reproductive mores, is examined here in its relevance to an intervention program for reducing the demographic pressure by increasing birth spacing. The mean birth interval of approximately three years appears to be shrinking, and is far too brief to prevent rapid population growth. The program, which included films about contraception, did not lead to a longer birth interval among the Bani-Iju, but did succeed in informing women about family planning. It is concluded that no intervention program for promotion of family planning is likely to be effective without substantial improvement in the economy.

    2006-09-01

    Full Text Available Levels and trends of various facets concerning first births are continuously changing. The evidence confirms that the postponement of first births is an ongoing and persisting process which started in western countries among cohorts of the 1940s, but only in the 1960s cohorts in Central and Eastern Europe. The mean age of women having first births is universally rising. Fertility of older women was increasing. The decline in childbearing of young women is robust among the cohorts of the late 1960s and the 1970s; in Southern Europe as well as in central and Eastern Europe the rates of decline have accelerated. Childbearing behavior in the formerly socialist countries is in transition to a different regime.

    Recent advances have documented the development of lung vasculature before and after birth, but less is known of the growth and maturation of airway vasculature. We sought to determine whether airway vasculature changes during the perinatal period and when the typical adult pattern develops. On embryonic day 16.5 mouse tracheas had a primitive vascular plexus unlike the adult airway vasculature, but instead resembling the yolk sac vasculature. Soon after birth (P0), the primitive vascular plexus underwent abrupt and extensive remodeling. Blood vessels overlying tracheal cartilage rings regressed from P1 to P3 but regrew from P4 to P7 to form the hierarchical, segmented, ladder-like adult pattern. Hypoxia and HIF-1α were present in tracheal epithelium over vessels that survived but not where they regressed. These findings reveal the plasticity of airway vasculature after birth and show that these vessels can be used to elucidate factors that promote postnatal vascular remodeling and maturation.

    Full Text Available OBJECTIVE: To evaluate the prognostic value of absent thumb pain sensation in newborns and young infants with birth brachial plexopathy. METHODS: We evaluated 131 patients with birth brachial plexopathy with less than two months of age. Pain sensation was evoked by thumb nail bed compression to evaluate sensory fibers of the upper trunk (C6. The patients were followed-up monthly. Patients with less than antigravity elbow flexion at six months of age were considered to have a poor outcome. RESULTS: Thirty patients had absent thumb pain sensation, from which 26 showed a poor outcome. Sensitivity of the test was 65% and specificity was 96%. CONCLUSION: Evaluation of thumb pain sensation should be included in the clinical assessment of infants with birth brachial plexopathy.

    Full Text Available Births occurring before 37 weeks resulting in prematurity poses serious hazards to the baby from delayed growth, neurodevelopmental anomalies to death and unfortunately India is in the top four countries with maximum preterm births and leads globally in deaths by prematurity. Infection is a very important component of the etiopathogenesis of preterm labor and periodontal disease is a rather unexplored aspect of infection very often overlooked by the general gynecologist and the dental practitioner equally. Periodontal disease is a potential foci of infectious pathogens which may disseminate hematogenously and effect the fetus. In this article, an effort has been made to find an evidence-based link between periodontal disease and preterm labor to drive home the conclusion that an early screening and diagnosis in pregnancy followed up with effective treatment of periodontal disease may significantly reduce the burden of preterm births.

    1982-07-01

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

    2000-10-01

    Whether homosexual pedophiles have more older brothers (a higher fraternal birth order) than do heterosexual pedophiles was investigated. Subjects were 260 sex offenders (against children age 14 or younger) and 260 matched volunteer controls. The subject's relative attraction to male and female children was assessed by phallometric testing in one analysis, and by his offense history in another. Both methods showed that fraternal birth order correlates with homosexuality in pedophiles, just as it does in men attracted to physically mature partners. Results suggest that fraternal birth order (or the underlying variable it represents) may prove the first identified universal factor in homosexual development. Results also argue against a previous explanation of the high prevalence of homosexuality in pedophiles (25% in this study), namely, that the factors that determine sexual preference in pedophiles are different from those that determine sexual preference in men attracted to adults. An alternative explanation in terms of canalization of development is suggested.

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

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

    We previously noted, in a small group of post-Fontan patients, a possible association between hepatic fibrosis scores and the status of pulmonary blood flow at birth. To further explore this observation, we examined data from all Fontan patients seen in our center from July 2010 to March 2015. We identified 200 patients for analysis. Of the 200 patients, 56 underwent transvenous-hepatic biopsy. Of the 200 patients, 13 (6.5%) had protein-losing enteropathy. We divided both the 56 biopsy patients and the entire cohort of 200 patients into 4 groups: (1) unobstructed pulmonary blood flow at birth with functional left ventricles, (2) unobstructed pulmonary blood flow at birth with functional right ventricles, (3) obstructed pulmonary blood flow at birth with functional left ventricles, and (4) obstructed pulmonary blood flow at birth with functional right ventricles. Analysis of the 56 liver-biopsy patient groups showed median hepatic total-fibrosis scores for the 4 groups of 2 (0-6), 2 (0-8), 3 (2-6), and 4 (1-8), respectively, with statistical significance between groups 4 and 1 (p = 0.031). For the entire cohort of 200 patients, we analyzed the incidence of protein-losing enteropathy for each of the four groups and found protein-losing enteropathy percent occurrences of 0, 2.9, 8.8, and 16.1, respectively, with statistical significance between groups 4 and 2 (p = 0.031) and between groups 4 and 1 (p = 0.025). A history of obstructed pulmonary blood flow at birth, coupled with a functional right ventricle, may predict a poorer long-term Fontan outcome.

    This papers underscores the intimate connection between the quantum walks generated by certain spin chain Hamiltonians and classical birth and death processes. It is observed that transition amplitudes between single excitation states of the spin chains have an expression in terms of orthogonal polynomials which is analogous to the Karlin-McGregor representation formula of the transition probability functions for classes of birth and death processes. As an application, we present a characterization of spin systems for which the probability to return to the point of origin at some time is 1 or almost 1.

    Alcohol Related Birth Defects (ARBD) are yet undocumented among past communities, although alcohol is the leading cause of non-heritable birth defects in the US today. We evaluate potential ARBD at Newton Plantation, Barbados (ca. 1660-1820), where earlier studies suggest frequent, community......-wide consumption of lead-tainted rum by enslaved Africans. Skeletons excavated in 1997-1998 (n= 45) were examined for congenital anomalies, using clinical/experimental descriptions to differentially diagnose possible ARBD. Enamel lead data served as a proxy for developmental exposure to tainted rum in a subsample...

    2010-01-01

    Given a birth-death process on N with semigroup P_t and a discrete gradient D depending on a positive weight u, we establish intertwining relations of the form D P_t = Q_t D, where Q_t is the Feynman-Kac semigroup with potential V_u of another birth-death process. We provide applications when V_u is positive and uniformly bounded from below, including Lipschitz contraction and Wasserstein curvature, various functional inequalities, and stochastic orderings. The proofs are remarkably simple and rely on interpolation, commutation, and convexity.

  18. The changing trends in live birth statistics in Korea, 1970 to 2010

    Science.gov (United States)

    2011-01-01

    Although Korean population has been growing steadily during the past four decades, the nation is rapidly becoming an aging society because of its declining birth rate combined with an increasing life expectancy. In addition, Korea has one of the lowest fertility rates in the world due to fewer married couples, advanced maternal age, and falling birth rate. The prevalence of low birth weight infants and multiple births has been increased compared with the decrease in the birth rate. Moreover, the number of congenital anomalies is expected to increase due to the advanced maternal age. In addition, the number of interracial children is expected to increase due to the rise in the number of international marriages. However, the maternal education level is high, single-mother birth rate is low, and the gender imbalance has lessened. The number of overweight babies has been decreased, as more pregnant women are receiving adequate prenatal care. Compared to the Asian average birth weight, the average birth weight is the highest in Asia. Moreover, the rate of low birth weight infants is low, and infant mortality is similarly low across Asia. Using birth data from Statistics Korea and studies of birth outcomes in Korea and abroad, this study aimed to assess the changes in maternal and infant characteristics associated with birth outcomes during the past four decades and identify necessary information infrastructures to study countermeasures the decrease in birth rate and increase in low birth weight infants in Korea.

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

    Using the Theory of Planned Behaviour (Ajzen, 1988) as a conceptual framework, 705 secondary school students were surveyed to identify their intentions to use birth control pills, condoms, and birth control pills in combination with condoms. Hierarchical multiple regression revealed that the theory explained between 23.5% and 45.8% of the variance in intentions. Variables external to the model such as past use, age, and ethnicity exhibited some independent effects. Attitudes were consistently predictive of intentions to use condoms, pills, and condoms in combination with pills for both male and female students. However, there were differences by gender in the degree to which subjective norms and perceived behavioural control predicted intentions. The findings suggest that programs should focus on: creation of positive attitudes regarding birth control pills and condoms; targeting important social influences, particularly regarding males' use of condoms; and developing strategies to increase students' control over the use of condoms.

    2015-01-01

    Background Few epidemiologic studies have investigated the use of venlafaxine (Effexor®), an antidepressant used to treat major depression and anxiety disorders in adults, during pregnancy. Our objective was to determine whether use of venlafaxine during pregnancy is associated with specific birth defects. Methods We used data from the National Birth Defects Prevention Study (NBDPS), a population-based, case-control study in the United States. Our analysis included mothers with pregnancies affected by one of 30 selected birth defects (cases) and babies without birth defects (controls) with estimated dates of delivery between 1997–2007. Exposure was any reported use of venlafaxine from one month preconception through the third month of pregnancy. We calculated adjusted odds ratios (aORs) and 95% Fisher’s Exact confidence intervals (CIs) for 24 birth defect groups for which at least 400 case mothers were interviewed. Our adjusted analyses controlled for maternal age and race-ethnicity. Results Among the 27,045 NBDPS participants who met inclusion criteria, 0.17% (14/8,002) of control mothers and 0.40% (77/19,043) of case mothers reported any use of venlafaxine from one month preconception through the third month of pregnancy. Statistically significant associations were found for anencephaly, atrial septal defect (ASD) secundum or ASD not otherwise specified, coarctation of the aorta, cleft palate, and gastroschisis. Conclusions Our data suggest associations between periconceptional use of venlafaxine and some birth defects. However, sample sizes were small, confidence intervals were wide, and additional studies are needed to confirm these results. PMID:23281074

    Full Text Available We examined the association between occupational lifting during pregnancy and risk of fetal death and preterm birth using a job exposure matrix (JEM.For 68,086 occupationally active women in the Danish National Birth Cohort, interview information on occupational lifting was collected around gestational week 16. We established a JEM based on information from women, who were still pregnant when interviewed. The JEM provided mean total loads lifted per day within homogeneous exposure groups as informed by job and industry codes. All women were assigned an exposure estimate from the JEM. We used Cox regression models with gestational age as underlying time variable and adjustment for covariates.We observed 2,717 fetal deaths and 3,128 preterm births within the study cohort. No exposure-response relation was observed for fetal death, but for women with a prior fetal death, we found a hazard ratio (HR of 2.87 (95% CI 1.37, 6.01 for stillbirth (fetal death ≥22 completed gestational weeks among those who lifted >200 kg/day. For preterm birth, we found an exposure-response relation for primigravid women, reaching a HR of 1.43 (95% CI 1.13, 1.80 for total loads >200 kg per day. These findings correspond to an excess fraction of 11% for stillbirth and 10% for preterm birth.We found an increased risk of stillbirth among women with a prior fetal death, who lifted >200 kg/day, and an exposure-response relationship between occupational lifting and preterm birth among primigravid women. The study adds to a large body of prospective studies on occupational lifting and adverse pregnancy outcomes by refined exposure assessment.

  4. Watching the Birth of a Galaxy Cluster?

    about 10,000 million light-years from the Earth (the redshift is 2.2), the VLT sees it as it was when the Universe was only about 20% of its present age. Previous observations of this galaxy by the same team of astronomers showed that its radio, X-ray and optical emission had many extreme characteristics that would be expected from a giant galaxy, forming at the centre of a rich cluster. However, because the galaxy is so distant, the cluster could not be seen directly. Radio data obtained by the Very Large Array (VLA) in the USA and X-ray data with the ROSAT satellite both indicated that the galaxy is surrounded by a hot gas similar to that observed at the centres of nearby rich clusters of galaxies. Most telling was a picture taken by the Hubble Space Telescope that revealed that the galaxy comprises a large number of clumps, and which bore a remarkable resemblance to computer models of the birth of giant galaxies in clusters. From these observations, it was concluded that 1138-262 is likely to be a massive galaxy in the final stage of assemblage through merging with many smaller galaxies in an infant rich cluster and the most distant known X-ray cluster.

  5. 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

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

    In rural, developing world communities, women are often isolated from biomedical services. Frequently, traditional birth attendants (TBAs) are the only caregivers during childbirth, both normal and complicated. Women trust their TBAs to manage their births. Globally, government and non-governmental organizations (NGOs) have sought to upgrade TBAs' skills and to encourage them to refer complications. However, most training programs have failed to change TBAs' practice substantially. Logistical barriers in reaching biomedical services in a timely manner are a key issue. Another is the difference between biomedical and traditional practitioners in the cognitive frameworks that shape decision making and management behaviors. The purpose of this study, conducted in Quintana Roo State, Mexico, was to listen to the voices of practicing Yucatec Maya TBAs (parteras) as they described decision making and management of complicated births. In-depth interviews with six practicing parteras in rural, isolated communities revealed that the parteras used traditional Maya ethnomedicine while valuing biomedical approaches. We isolated themes in decision making and mapped management of birth complications. Integrating TBAs' traditional knowledge into biomedical training programs is one way to honor their knowledge and make training relevant.

    This study used data from the Birth in Brazil survey, a nationwide hospital-based study of 24,197 postpartum women and their newborns, collected between February 2011 and July 2012. A three-stage cluster sampling design (hospitals, days, women) was used consisting of stratification by geographic region, type of municipality (capital or non-capital), and type of hospital financing. Logistic regression was used to identify variables that were potential predictors of neonatal mortality and neonatal near miss indicators. After testing nineteen variables, five were chosen to compose a set of neonatal near miss indicators (birth weight of less than 1,500 g, Apgar score of less than 7 in the 5th minute of life, use of mechanical ventilation, gestational age of less than 32 weeks and congenital malformations). The neonatal near miss rate in the Birth in Brazil survey was 39.2 per thousand live births, three and a half times higher than the neonatal mortality rate (11.1 per thousand). These neonatal near miss indicators were able to identify situations with a high risk of neonatal death.

    Mammals must inflate their lungs and breathe within minutes of birth to survive. A key regulator of neonatal lung inflation is pulmonary surfactant, a lipoprotein complex which increases lung compliance by reducing alveolar surface tension (Morgan, 1971). Whether other developmental processes also alter lung mechanics in preparation for birth is unknown. We identify prenatal lymphatic function as an unexpected requirement for neonatal lung inflation and respiration. Mice lacking lymphatic vessels, due either to loss of the lymphangiogenic factor CCBE1 or VEGFR3 function, appear cyanotic and die shortly after birth due to failure of lung inflation. Failure of lung inflation is not due to reduced surfactant levels or altered development of the lung but is associated with an elevated wet/dry ratio consistent with edema. Embryonic studies reveal active lymphatic function in the late gestation lung, and significantly reduced total lung compliance in late gestation embryos that lack lymphatics. These findings reveal that lymphatic vascular function plays a previously unrecognized mechanical role in the developing lung that prepares it for inflation at birth. They explain respiratory failure in infants with congenital pulmonary lymphangiectasia, and suggest that inadequate late gestation lymphatic function may also contribute to respiratory failure in premature infants.

  7. Antihistamines and Birth Defects: A Systematic Review of the Literature

    Gilboa, Suzanne M.; Ailes, Elizabeth C.; Rai, Ramona P.; Anderson, Jaynia A.; Honein, Margaret A.

    2015-01-01

    Introduction Approximately 10-15% of women reportedly take an antihistamine during pregnancy for the relief of nausea and vomiting, allergy and asthma symptoms, or indigestion. Antihistamines include histamine H1-receptor and H2-receptor antagonists. Areas covered This is a systematic evaluation of the peer-reviewed epidemiologic literature published through February 2014 on the association between prenatal exposure to antihistamines and birth defects. Papers addressing histamine H1- or H2-receptor antagonists are included. Papers addressing pyridoxine plus doxylamine (Bendectin in the United States, Debendox in the United Kingdom, Diclectin in Canada, Lenotan and Merbental in other countries) prior to the year 2001 were excluded post-hoc because of several previously published meta-analyses and commentaries on this medication. Expert opinion The literature on the safety of antihistamine use during pregnancy with respect to birth defects is generally reassuring though the positive findings from a few large studies warrant corroboration in other populations. The findings in the literature are considered in light of three critical methodological issues: (1) selection of appropriate study population; (2) ascertainment of antihistamine exposures; and (3) ascertainment of birth defects outcomes. Selected antihistamines have been very well-studied (e.g. loratadine); others, especially H2- receptor antagonists, require additional study before an assessment of safety with respect to birth defects risk could be made.

  15. Introducing Midwifery-led Birth Centres to Ontario

    Directory of Open Access Journals (Sweden)

    Cristina A. Mattison

    2015-03-01

    Full Text Available In Ontario, maternal health systems are changing, with an increasing variety of childbirth options being offered to low-risk pregnant women. Midwifery became a regulated profession in the province in 1994: providing primary care throughout pregnancy, labour and for up to six weeks postpartum. Currently there are three midwifery-led birth centres operating in Ontario, two of which opened in early 2014. The Ministry of Health and Long-Term Care (MoHLTC has launched these new birth centres in order to offer women more choice in health care provider and birth setting. This shift is representative of the MoHLTC’s push to move services out of hospitals and into community-based settings. While the birth centre initiative is in its early stages and a formal program evaluation is needed, it has the potential, if scaled up, to decrease the need for hospital beds as well as reduce health care costs through more appropriate care for low-risk pregnancies, leading to fewer interventions.

  16. Fertility change in Egypt: From second to third birth

    Directory of Open Access Journals (Sweden)

    Daniele Vignoli

    2006-12-01

    Full Text Available This work focuses on Egypt, a country that notwithstanding its advanced stage of socio-demographic transition has shown near stagnation in the reduction of fertility levels in the last decade. The progression from second to third birth is a crucial component in fertility change, since the reduction especially of third and higher-order births maintains the fertility decline. For this reason, the study aims at analyzing the main determinants of the third-birth intensities of Egyptian two-child mothers, applying an event-history analysis to the 2000 Egyptian Demographic and Health Survey. The study's results show that fertility differentials among the country's social groups continue to persist. Moreover, the difficult change in the fertility of women with high educational standards seems to be responsible for the stalling fertility decline during recent years. The analysis, however, has demonstrated that within the framework of the ongoing process of modernization in the country, even the most laggard groups of women showed a decrease in third-birth intensity during the 1990s. The study also reveals that the preference for at least one son in the family on the progression to the third child is weakening among women who have completed secondary education.

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

    Eighteen of 901 women (2%) attempting vaginal birth after cesarean delivery (VBAC) received amnioinfusion. No untoward effects occurred in the subjects or their fetuses. We conclude that, though amnioinfusion in the setting of a VBAC attempt is needed only infrequently, it appears to be a reasonable intrapartum management option. The usual safeguards for a VBAC attempt should be followed.

    Objective We sought to employ an innovative tool based on common biological pathways to identify specific phenotypes among women with spontaneous preterm birth (SPTB), in order to enhance investigators' ability to identify to highlight common mechanisms and underlying genetic factors responsible for SPTB. Study Design A secondary analysis of a prospective case-control multicenter study of SPTB. All cases delivered a preterm singleton at SPTB ≤34.0 weeks gestation. Each woman was assessed for the presence of underlying SPTB etiologies. A hierarchical cluster analysis was used to identify groups of women with homogeneous phenotypic profiles. One of the phenotypic clusters was selected for candidate gene association analysis using VEGAS software. Results 1028 women with SPTB were assigned phenotypes. Hierarchical clustering of the phenotypes revealed five major clusters. Cluster 1 (N=445) was characterized by maternal stress, cluster 2 (N=294) by premature membrane rupture, cluster 3 (N=120) by familial factors, and cluster 4 (N=63) by maternal comorbidities. Cluster 5 (N=106) was multifactorial, characterized by infection (INF), decidual hemorrhage (DH) and placental dysfunction (PD). These three phenotypes were highly correlated by Chi-square analysis [PD and DH (p<2.2e-6); PD and INF (p=6.2e-10); INF and DH (p=0.0036)]. Gene-based testing identified the INS (insulin) gene as significantly associated with cluster 3 of SPTB. Conclusion We identified 5 major clusters of SPTB based on a phenotype tool and hierarchal clustering. There was significant correlation between several of the phenotypes. The INS gene was associated with familial factors underlying SPTB. PMID:26070700

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

    Directory of Open Access Journals (Sweden)

    Alexandria N Ardissone

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

  5. Non-seasonality of births in Tierra del Fuego (Chile).

    2000-01-01

    Tierra del Fuego is situated at the southern tip of the American continent, which conditions its environmental and climatic characteristics. The colonizing population arrived, at the end of the 19th century, from other Chilean regions (particularly from Chiloé) and diverse European countries, especially Britain and Croatia, but also Germany, Spain and Italy. In the present study, the existence of a seasonal pattern in 5430 births registered in the Chilean population of Tierra del Fuego from 1890 to 1995 was analysed. The analysis showed no seasonal distribution of births in the periods 1890-1920 and from 1946 to the present day, a phenomenon rarely reported in the literature. The absence of seasonality in birth distribution could be related to the great diversity in the origins of the population's families, the constant renovation of this and the declining importance of the administrative capital of the province of Tierra del Fuego, Porvenir, in favour of Punta Arenas, capital of the Magellanic region. In the period of maximum development of the capital of the province, a seasonal pattern was detected with a peak in April and a trough in October, which corresponds with a maximum of conceptions in July and, in general, during the early southern winter and a decline in births from late spring to mid-summer, with a trough in January. This birth distribution is interpreted as a subordination of activity and social life to the annual sheep cycle. In addition to temporal trends, the influence on the observed patterns of environmental parameters, father's occupation, seasonality of marriage and the origin of the parents were analysed.

    The spiny mouse is relatively mature at birth. We hypothesized that like other organs, the kidney may be more developed in the spiny mouse at birth, than in other rodents. If nephrogenesis is complete before birth, the spiny mouse may provide an excellent model with which to study the effects of an altered intrauterine environment on renal development. Due to its desert adaptation, the spiny mouse may have a reduced cortex-to-medulla ratio but an equivalent total nephron number to the C57/BL mouse. Kidneys were collected from fetal and neonatal spiny mice and sectioned for gross examination of metanephric development. Kidneys were collected from adult spiny mice (10 wk of age), and glomerular number, volume, and cortex-to-medulla ratios were determined using unbiased stereology. Nephrogenesis is complete in spiny mouse kidneys before birth. Metanephrogenesis begins at approximately day 18, and by day 38 of a 40-day gestation, the nephrogenic zone is no longer present. Spiny mice have a significantly (P < 0.001) lower total nephron number compared with C57/BL mice, although the total glomerular volume is similar. The cortex-to-medulla ratio of the spiny mouse is significantly (P < 0.01) smaller. The spiny mouse is the first rodent species shown to complete nephrogenesis before birth. This makes it an attractive candidate for the study of fetal and neonatal kidney development and function. The reduced total nephron number and cortex-to-medulla ratio in the spiny mouse may contribute to its ability to highly concentrate its urine under stressful conditions (i.e., dehydration).

    Full Text Available Introduction: Current medical technologies in care in birth increased maternal and fetal benefits persist, despite numerous unnecessary procedures. The purpose of the normal childbirth care is to have healthy women and newborns, using a minimum of safe interventions. Objective: To analyze the assistance to normal delivery in secondary care maternity. Methodology: A total of 100 primiparous mothers who had vaginal delivery were included, in which care practices used were categorized: 1 according to the WHO classification for assistance to normal childbirth: effective, harmful, used with caution and used inappropriately; 2 associating calculations with the Bologna Index parameters: presence of a birth partner, partograph, no stimulation of labor, delivery in non-supine position, and mother-newborn skin-to-skin contact. Results: Birth partners (85%, correctly filled partographs (62%, mother-newborn skin-to-skin contact (36%, use of oxytocin (87%, use of parenteral nutrition during labor (86% and at delivery (74%, episiotomy (94% and uterine fundal pressure in the expulsion stage (58%. The overall average value of the Bologna Index of the mothers analyzed was 1.95. Conclusions: Some effective procedures recommended by WHO (presence of a birth partner, some effective and mandatory practices were not complied with (partograph completely filled, potentially harmful or ineffective procedures were used (oxytocin in labor/post-partum, as well as inadequate procedures (uterine fundal pressure during the expulsion stage, use of forceps and episiotomy.

    Birth defects remain the leading cause of infant death in US. The field of teratology has been focused on the causes and underlying mechanisms of birth defects for decades, yet our understanding of these critical issues remain unacceptably vague. Conclusions from years of animal and human studies made it clear that the vast majority of birth defects have multifactorial origins, with contributions from environmental and genetic factors. The environment comprises not only of the physical, biological, and chemical external environment surrounding the pregnant woman, but it also includes the internal environment of the woman's body that interact with the developing embryo in a complex fashion. The importance of maternal and embryonic genetic factors consisting of countless genetic variants/mutations that exist within every individual contribute to birth defect susceptibility is only now being more fully appreciated. This great complexity of the genome and its diversity within individuals and populations seems to be the principal reason why the same teratogenic exposure can induce severe malformation in one embryo, while fail to do so to other exposed embryos. As the interaction between genetic and environmental factors has long been recognized as the first "Principle of Teratology" by Wilson and Warkany [1965. Teratology: Principles and techniques. Chicago: University of Chicago Press], it is only recently that the appropriate investigative tools have been developed with which to fully investigate this fundamental principle. The introduction of high throughput technologies like whole genome sequencing or genome-wide association studies are promising to deliver an enormous amount of new data that will shed light on the genomic factors that contribute susceptibility to environmental teratogens. In this review, we attempt to summarize the epidemiological and experimental literature concerning birth defects whose phenotypic expression can be clearly related to the

    2007-01-01

    Full Text Available Background: Human sex ratio at birth differs from one population to the other. This variation has been attributed to cultural practices, seasonal variation, small-family size policy and sex selective technology. Information on secondary sex ratio in Nigeria is limited. Aims and Objective: To analyzed human sex ratio at birth for samples of the Nigerian population in 4 urban settings in Southwest Nigeria, in order to know the trend and to compare the findings with those of previous reports. Materials and Methods: Data were collected from Obafemi Awolowo University (OAU teaching hospital at Ile Ife and Wesley Guild hospital at Ilesa, Osun state; General hospital at Ogbomoso, Oyo state and Ekiti state specialist hospital at Ado-Ekiti, Ekiti state. The data consisted of 35 209 live single births recorded between 1995 and 2004. Each set of data was analyzed to determine the sex ratio by year, month and quarterly values. Chi-square analysis was used to determine the deviation of the sex ratios for the years from the average value. Results: The annual average ratios of 104.7:100, 102.8:100, 98.9:100 and 100.8:100 were recorded for OAU teaching hospital, Wesley Guild Hospital, General Hospital and Ekiti State specialist hospital, respectively. When pooled together, the average ratio was 102.7:100. This shows some bias for male births. Data also indicates more male birth in the rainy season, suggesting a seasonal variation of sex ratio. Conclusion: These findings are representative of the populations in southwest Nigeria and are comparable to values obtained for other regions in Nigeria and other populations of African origin.

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

    Estrous cycle asynchrony likely functions to elevate individual females' sexual attractiveness during female mate choice. Female chimpanzees show physiological estrus as anogenital swelling. Copulations are concentrated during the period of maximal tumescence, which is called the estrous period. A group of female chimpanzees in Mahale Mountains National Park, Tanzania, was shown to display asynchrony in both maximal tumescence and periovulatory periods. We tested the hypothesis that females establish asynchronous maximal tumescence or periovulatory periods with respect to other females to increase copulation frequency and birth opportunities (Hypothesis 1). We analyzed differences in birth rates between four asynchronous years and five nonasynchronous years. Counter to Hypothesis 1, females in periovulatory periods during asynchronous years showed significantly lower birth rates than those in nonasynchronous years. In addition, periovulatory females copulated more frequently on days on which no other female in a periovulatory period was present. These results suggest that birth rates tend to decrease when females experience nonoverlapping ovulation cycles, although copulation frequency is high. Such a decrease in the birth rate may have resulted from the cost associated with multiple copulations. We tested two other hypotheses: paternity confusion (Hypothesis 2) and sperm competition (Hypothesis 3). Both of these hypotheses were partially supported. The highest-ranking male most effectively monopolized access to receptive females when relatively few other males and receptive females from the party (or subgroup) were present. The viability of Hypotheses 2 and 3 requires that dominant males are able to hinder a female from mating with other males. Given that the male-biased operational sex ratio created by female asynchrony is likely to reduce the efficiency of mate guarding by dominant males, an asynchronous female may gain a fitness benefit by increasing the

    Secondary recurrent miscarriage (RM) is defined as three or more consecutive pregnancy losses after delivery of a viable infant. Previous reports suggest that a firstborn male child is associated with less favourable subsequent reproductive potential, possibly due to maternal immunisation against male-specific minor histocompatibility antigens. In a retrospective cohort study of 85 cases of secondary RM we aimed to determine if secondary RM was associated with (i) gender of previous child, maternal age, or duration of miscarriage history, and (ii) increased risk of pregnancy complications. Fifty-three women (62.0%; 53\\/85) gave birth to a male child prior to RM compared to 32 (38.0%; 32\\/85) who gave birth to a female child (p=0.002). The majority (91.7%; 78\\/85) had uncomplicated, term deliveries and normal birth weight neonates, with one quarter of the women previously delivered by Caesarean section. All had routine RM investigations and 19.0% (16\\/85) had an abnormal result. Fifty-seven women conceived again and 33.3% (19\\/57) miscarried, but there was no significant difference in failure rates between those with a previous male or female child (13\\/32 vs. 6\\/25, p=0.2). When patients with abnormal results were excluded, or when women with only one previous child were considered, there was still no difference in these rates. A previous male birth may be associated with an increased risk of secondary RM but numbers preclude concluding whether this increases recurrence risk. The suggested association with previous male birth provides a basis for further investigations at a molecular level.

    Birth dates from almost 3 million babies born between 1969 and 2005 in Switzerland were analyzed for the weekday of birth. As in other countries but with unprecedented amplitude, a very marked non-random distribution was discovered with decreasing numbers of births on weekends, reaching -17.9% in 2005. While most of this weekend births avoidance rate is due to fewer births on Sundays (up to -21.7%), the downward trend is primarily a consequence of decreasing births on Saturdays (up to -14.5%). For 2005, these percentages mean that 3,728 fewer babies are born during weekends than could be expected from equal distribution. Most interestingly and surprisingly, weekend birth-avoiding rates are significantly correlated with birth numbers ( r = 0.86), i.e. the lower the birth number per year, the lower the number of weekend births. The increasing avoidance of births during weekends is discussed as being a consequence of increasing numbers of caesarean sections and elective labor induction, which in Switzerland reach 29.2 and 20.5%, respectively, in 2004. This hypothesis is supported by the observation that both primary and secondary caesarean sections are significantly correlated with weekend birth avoidance rates. It is therefore likely that financial aspects of hospitals are a factor determining the avoidance of weekend births by increasing the numbers of caesarean sections.

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

    This study used linked foster care and birth records to provide a longitudinal, population-level examination of the incidence of first and repeat births among girls who were in foster care at age 17. Girls in a foster care placement in California at the age of 17 between 2003 and 2007 were identified from statewide child protection records. These records were probabilistically matched to vital birth records spanning the period from 2001 to 2010. Linked data were used to estimate the cumulative percentage of girls who had given birth before age 20. Birth rates and unadjusted risk ratios were generated to characterize foster care experiences correlated with heightened teen birth rates. Between 2003 and 2007 in California, there were 20,222 girls in foster care at age 17. Overall, 11.4% had a first birth before age 18. The cumulative percentage who gave birth before age 20 was 28.1%. Among girls who had a first birth before age 18, 41.2% had a repeat teen birth. Significant variations by race/ethnicity and placement-related characteristics emerged. Expanded data and rigorous research are needed to evaluate prevention efforts and ensure parenting teens are provided with the needed services and supports.

    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

    Birth defects and genetic disorders are leading causes of infant morbidity and mortality in many countries. Population-based data on birth defects among Arab-American children have not been documented previously. Michigan has the second largest Arab-American community in the United States after California. Using data from the Michigan Birth Defects Registry (MBDR), which includes information on parents' country of birth and ancestry, birth prevalences were estimated in offspring of Michigan women of Arab ancestry for 21 major categories of birth defects and 12 congenital endocrine, metabolic, and hereditary disorders. Compared with other non-Hispanic white children in Michigan, Arab-American children had similar or lower birth prevalences of the selected types of structural birth defects, with higher rates of certain hereditary blood disorders and three categories of metabolic disorders. These estimates are important for planning preconception and antenatal health care, genetic counseling, and clinical care for Arab Americans.
