    This study examines the association between maternal factors and low birth weight among newborns at a tertiary hospital in Malaysia. This was a cross-sectional study where mothers were followed through from first booking till delivery. There were 666 mothers who delivered from May 2007 to March 2008. Infants' birth weight were compared with maternal age, pre-pregnancy BMI, fathers BMI, parity, ethnicity, per capita monthly income, and maternal blood pressure during pregnancy. A multiple logistic regressions was used to determine the relationship of maternal factors and low birth weight, while the ROC curve was constructed to assess the sensitivity and specificity of the predictive model. Among the significant risk factors of low birth weight were older age (35 years and above), low pre-pregnancy BMI (per capita monthly income were included in the analysis.

    The objective of this study was to develop a transparent, comprehensive, and flexible model for each trait for the formulation of breeding objectives for sow traits in swine breeding programs. Economic values were derived from submodels considering a typical Australian pig production system. Differences in timing and expressions of traits were accounted for to derive economic weights that were compared on the basis of their relative size after multiplication by their corresponding genetic standard deviation to account for differences in scale and genetic variability present for each trait. The number of piglets born alive had the greatest contribution (27.1%) to a subindex containing only maternal traits, followed by daily gain (maternal; 22.0%) and sow mature weight (15.0%). Other traits considered in the maternal breeding objective were preweaning survival (11.8%), sow longevity (12.5%), gilt age at puberty (8.7%), and piglet survival at birth (3.1%). The economic weights for number of piglets born alive and preweaning piglet survival were found to be highly dependent on the definition of scale of enterprise, with each economic value increasing by approximately 100% when it was assumed that the value of extra output per sow could be captured, rather than assuming a consequent reduction in the number of sows to maintain a constant level of output from a farm enterprise. In the context of a full maternal line index that must account also for the expression of direct genetic traits by the growing piglet progeny of sows, the maternal traits contributed approximately half of the variation in the overall breeding objective. Deployment of more comprehensive maternal line indexes incorporating the new maternal traits described would lead to more balanced selection outcomes and improved survival of pigs. Future work could facilitate evaluation of the economic impacts of desired-gains indexes, which could further improve animal welfare through improved sow and piglet

    Maternal breastfeeding is a habit that has been closely linked to the survival of the human species since time immemorial. Following a stage when it was massively abandoned in the mid-XX century, we are now witnessing a recovery of this habit, especially in the so-called "developed" world, promoted by the health institutions in light of the scientific evidence. The superiority of maternal breastfeeding over artificial feeding is beyond dispute as the scientific evidence makes clear. Maternal breastfeeding is a positive factor for the health of the mother and for the child. Hence the promotion and recovery of this habit is more than just a fashion or tendency: it is an incontrovertible factor in maternal-child health. Through the Foral Order of January 28th 2004, the government of Navarre has brought together the numerous administrative initiatives that are emerging in our province for the promotion of maternal breastfeeding by promoting a Technical Advisory Commission for the Promotion of Maternal Breastfeeding in Navarre.

    OBJECTIVE Congenital hydrocephalus (CH) is one of the most frequent CNS congenital malformations, representing an entity with serious pathological consequences. Although several studies have previously assessed child-related risk factors associated with CH development, there is a gap of knowledge on maternal environmental risk factors related to CH. The authors have systematically assessed extrinsic factors in the maternal environment that potentially confer an increased risk of CH development. METHODS The Cochrane Library, MEDLINE, and EMBASE were systematically searched for works published between 1966 and December 2015 to identify all relevant articles published in English. Only studies that investigated environmental risk factors concerning the mother-either during gestation or pregestationally-were included. RESULTS In total, 13 studies (5 cohorts, 3 case series, 3 case-control studies, 1 meta-analysis, and 1 case report) meeting the inclusion criteria were identified. Maternal medication or alcohol use during gestation; lifestyle modifiable maternal pathologies such as obesity, diabetes, or hypertension; lack of prenatal care; and a low socioeconomic status were identified as significant maternal environmental risk factors for CH development. Maternal infections and trauma to the mother during pregnancy have also been highlighted as potential mother-related risk factors for CH. CONCLUSIONS Congenital hydrocephalus is an important cause of serious infant health disability that can lead to health inequalities among adults. The present study identified several maternal environmental risk factors for CH, thus yielding important scientific information relevant to prevention of some CH cases. However, further research is warranted to confirm the impact of the identified factors and examine their underlying behavioral and/or biological basis, leading to the generation of suitable prevention strategies.

    Full Text Available Neural tube defects (NTDs may be associated with syndromes, disorders, and maternal and fetal risk factors. This article provides a comprehensive review of the syndromes, disorders, and maternal and fetal risk factors associated with NTDs, including maternal fumonisin consumption, periconceptional zinc deficiency, parental occupational exposure and residential proximity to pesticides, lower socioeconomic status, fetal alcohol syndrome, mutations in the VANGL1 gene, human athymic Nude/SCID fetus, and single nucleotide polymorphism in the NOS3 gene. NTDs associated with these syndromes, disorders, and maternal and fetal risk factors are a rare but important cause of NTDs. The recurrence risk and the preventive effect of maternal folic acid intake in NTDs associated with syndromes, disorders and maternal risk factors may be different from those of nonsyndromic multifactorial NTDs. Perinatal diagnosis of NTDs should alert doctors to the syndromes, disorders, and maternal and fetal risk factors associated with NTDs, and prompt thorough etiologic investigation and genetic counseling.

    Objective To identify factors associated with maternal death in patients admitted to an intensive care unit. Methods A cross-sectional study was conducted in a maternal intensive care unit. All medical records of patients admitted from January 2012 to December 2014 were reviewed. Pregnant and puerperal women were included; those with diagnoses of hydatidiform mole, ectopic pregnancy, or anembryonic pregnancy were excluded, as were patients admitted for non-obstetrical reasons. Death and hospital discharge were the outcomes subjected to comparative analysis. Results A total of 373 patients aged 13 to 45 years were included. The causes for admission to the intensive care unit were hypertensive disorders of pregnancy, followed by heart disease, respiratory failure, and sepsis; complications included acute kidney injury (24.1%), hypotension (15.5%), bleeding (10.2%), and sepsis (6.7%). A total of 28 patients died (7.5%). Causes of death were hemorrhagic shock, multiple organ failure, respiratory failure, and sepsis. The independent risk factors associated with death were acute kidney injury (odds ratio [OR] = 6.77), hypotension (OR = 15.08), and respiratory failure (OR = 3.65). Conclusion The frequency of deaths was low. Acute kidney injury, hypotension, and respiratory insufficiency were independent risk factors for maternal death. PMID:28099637

  11. The impact of maternal characteristics, infant temperament and contextual factors on maternal responsiveness to infant.

    Postnatal maternal depressive symptoms are consistently associated with impairments in maternal attunement (i.e., maternal responsiveness and bonding). There is a growing body of literature examining the impact of maternal cognitive factors (e.g., rumination) on maternal attunement and mood. However, little research has examined the role of infant temperament and maternal social support in this relationship. This study investigated the hypothesis that rumination would mediate (1) the relationship between depressive symptoms and attunement and (2) the relationship between social support and attunement. We further predicted that infant temperament would moderate these relationships, such that rumination would demonstrate mediating effects on attunement when infant difficult temperament was high, but not low. Two hundred and three mothers completed measures on rumination, depressive symptoms, attunement, perceived social support and infant temperament. Rumination mediated the effect of postnatal maternal depressive mood on maternal self-reported responsiveness to the infant when infants were low, but not high, in negative temperament. When infants had higher negative temperament, there were direct relationships between maternal depressive symptoms, social support and maternal self-reported responsiveness to the infant. This study is limited by its cross-sectional and correlational nature and the use of self-report measures to assess a mother's awareness of her infant needs and behaviours, rather than observational measures of maternal sensitivity. These findings suggest potentially different pathways to poor maternal responsiveness than those expected and provide new evidence about the contexts in which maternal cognitive factors, such as rumination, may impact on the mother-infant relationship.

  12. The neglected role of insulin-like growth factors in the maternal circulation regulating fetal growth.

    2011-01-01

    Maternal insulin-like growth factors (IGFs) play a pivotal role in modulating fetal growth via their actions on both the mother and the placenta. Circulating IGFs influence maternal tissue growth and metabolism, thereby regulating nutrient availability for the growth of the conceptus. Maternal IGFs also regulate placental morphogenesis, substrate transport and hormone secretion, all of which influence fetal growth either via indirect effects on maternal substrate availability, or through direct effects on the placenta and its capacity to supply nutrients to the fetus. The extent to which IGFs influence the mother and/or placenta are dependent on the species and maternal factors, including age and nutrition. As altered fetal growth is associated with increased perinatal morbidity and mortality and a greater risk of developing degenerative diseases in adult life, understanding the role of maternal IGFs during pregnancy is essential in order to identify mechanisms underlying altered fetal growth and offspring programming.

    It has been proposed that maternal health and nutrition may be important in the development of adult cardiovascular risk, and that blood pressure may be an important intermediate step in this process. To examine the relevance of this hypothesis in contemporary British children, the relationships of several maternal factors to blood pressure were studied in 3360 children of European origin aged 5-7 years. Maternal age, height, and body mass index were all positively related to blood pressure i...

    The objective of the study was to assess the impact of maternal history of adoption or foster care placement in childhood on the risk for preterm birth (PTB), controlling for other known risk factors for PTB. Participants were 302 pregnant women from a low-income, diverse sample drawn from 2 intensive prospective studies of maternal mood and behavior and fetal and infant development. Gestational age was determined by best obstetric estimate. Maternal history of adoption or foster care placement prior to age 18 years was determined by maternal report. Other maternal characteristics, including maternal medical conditions, psychosocial characteristics, and health behaviors, were measured during the second and third trimesters of pregnancy. The odds of delivering preterm (gestational age foster care placement compared with women who were never placed out of the home during childhood. This association remained significant after adjusting for other known risk factors for PTB including maternal medical conditions, psychosocial characteristics, and negative health behaviors in pregnancy. Findings suggest that a history of adoption/foster care placement is an important risk factor for PTB and may be comparable with other established risk factors for PTB including prior history of PTB, body mass index, African-American race, and advanced maternal age. More studies are needed to understand why women with placement histories may be at increased risk to deliver preterm. Copyright © 2014 Elsevier Inc. All rights reserved.

    Mammalian early embryogenesis is supported by maternal factors, such as messenger RNA (mRNA) and proteins, produced and accumulated during oogenesis at least up to the stage when zygotic activation commences. These maternal factors are involved in biologically important events such as epigenetic activation, reprogramming, and mitochondrial growth. Most of these maternal mRNAs are degraded by the 2-cell to 4 ~ 8-cell stages. Maternal proteins, which are produced during oogenesis or by the maternal mRNAs, are degraded by the 4 ~ 8-cell stage. In other words, the maternal factors exist during specific stages of early embryogenesis. In this chapter, we will briefly summarize the property of these maternal factors and mention possible applications of these factors for developing new reproduction engineering-related technologies and producing genetically modified animals. More specifically, we will show the usefulness of maternally accumulated Cas9 protein as a promising tool for CRISPR-/Cas9-based simultaneous genetic modification of multiple loci in mammals.

    Knowledge of the relative contributions of risk factors in predicting young children's behavior problems may provide insights for the development of preventive interventions. The purpose of this cross-sectional study was to identify maternal predictors of children's internalizing and externalizing behaviors in a volunteer sample of 205 low-income, single mothers with children between 2 and 6 years of age. Data were collected on chronic stressors, self-esteem, negative thinking, depressive symptoms, and child behavior during in-home interviews with the mothers. Mothers' reports of internalizing and externalizing behaviors did not differ by sex or race of the child. Chronic stressors and depressive symptoms, in addition to control variables, explained 27% of the variability in internalizing behavior while these two variables accounted for 21% of the variability in externalizing behavior. For both internalizing and externalizing behavior, chronic stressors exerted the largest total effects. The effects of self-esteem and negative thinking were indirect, with the latter playing a stronger role. The indirect effect of negative thinking on child behavior was exerted through depressive symptoms, while self-esteem was linked with child behavior through both negative thinking and depressive symptoms. Decreasing mothers' negative thinking, a variable amenable to intervention, may not only decrease a mother's depressive symptoms but also improve her perception of the child's behavior. Decreasing mothers' negative thinking may provide a way to reduce their depressive symptoms and result in fewer behavior problems among their young children. Nurses working in primary care and community-based settings are in key positions to address this problem and improve the mental health of low-income mothers and positively affect the behavior of their children.

    Conclusion: Based on our findings, some factors including multiparity, pregnancy his-tory more than 4 times, short interval between pregnancies lower than 2 years and ma-ternal age more than 35 years were some risk factors for maternal death. Maternal mortality in the postpartum period was more than pre-delivery period. Bleeding was the main cause of maternal mortality. Therefore monitoring of vital signs in the post-partum period and the proper management of bleeding are very important. It is sug-gested that risk assessment should be done for pregnant women in delivery ward for detecting high risk pregnant women. Suitable management for these women especially for patients with postpartum hemorrhage plays an important role to decrease the ma-ternal mortality.

    This paper explores the effect of risk and socioeconomic factors on maternal mortality at the community level in Madagascar using a unique, nationwide panel of communes (i.e., counties). Previous work in this area uses individual or cross-country data to study maternal mortality, however, studying maternal mortality at the community level is imperative because this is the level at which most policy is implemented. The results show that longer travel time from the community to the hospital leads to a high level of maternal mortality. The findings suggest that improvement to transportation systems and access to hospitals with surgery rooms are needed to deal with obstetric complications and reduce maternal mortality.

    Full Text Available Abstract Background Maternal health is one of the major worldwide health challenges. Currently, the unacceptably high levels of maternal mortality are a common subject in global health and development discussions. Although some countries have made remarkable progress, half of the maternal deaths in the world still take place in Sub-Saharan Africa where little or no progress has been made. There is no single simple, straightforward intervention that will significantly decrease maternal mortality alone; however, there is a consensus on the importance of a strong health system, skilled delivery attendants, and women's rights for maternal health. Our objective was to describe and determine different factors associated with the maternal mortality ratio in Sub-Saharan countries. Methods An ecological multi-group study compared variables between many countries in Sub-Saharan Africa using data collected between 1997 and 2006. The dependent variable was the maternal mortality ratio, and Health care system-related, educational and economic indicators were the independent variables. Information sources included the WHO, World Bank, UNICEF and UNDP. Results Maternal mortality ratio values in Sub-Saharan Africa were demonstrated to be high and vary enormously among countries. A relationship between the maternal mortality ratio and some educational, sanitary and economic factors was observed. There was an inverse and significant correlation of the maternal mortality ratio with prenatal care coverage, births assisted by skilled health personnel, access to an improved water source, adult literacy rate, primary female enrolment rate, education index, the Gross National Income per capita and the per-capita government expenditure on health. Conclusions Education and an effective and efficient health system, especially during pregnancy and delivery, are strongly related to maternal death. Also, macro-economic factors are related and could be influencing the others.

    To assess the rate of maternal complications related to cesarean section (CS) and to compare morbidity between elective, emergency and crash-emergency CS. To establish risk factors associated with maternal CS morbidity. A prospective multicenter cohort study. Twelve delivery units in Finland. Women delivering by CS (n = 2,496) during a 6 months period in the study hospitals. Data on pregnant women, CS, and maternal recovery during the hospital stay was collected prospectively on report forms. The complication rates by different CSs were calculated, and factors associated with morbidity were analyzed by odds ratios (OR). Maternal complication rates in different types of CS. The association of risk factors with morbidity. About 27% of women delivering by CS had complications; 10% had severe complications. The complication rate was higher in emergency CS than in elective CS, and highest in crash-emergency CS. Significant independent risk factors for maternal morbidity were emergency CS and crash-emergency CS compared to elective CS (OR 1.8; 95% confidence interval (CI) 1.5-2.2), pre-eclampsia (OR 1.5; CI 1.1-2.0), maternal obesity (OR 1.4; CI 1.1-1.8) and maternal increasing age (OR 1.1; CI 1.03-1.2 per each 5 years). Maternal complications are frequent in CS, and although performing CS electively reduces the occurrence of complications, the frequency is still high. The complication rate depends on the degree of emergency, and increases with maternal obesity, older age and pre-eclampsia.

    Full Text Available Abstract Background Utilization of maternal health services is associated with improved maternal and neonatal health outcomes. Considering global and national interests in the Millennium Development Goal and Nigeria's high level of maternal mortality, understanding the factors affecting maternal health use is crucial. Studies on the use of maternal care services have largely overlooked community and other contextual factors. This study examined the determinants of maternal services utilization in Nigeria, with a focus on individual, household, community and state-level factors. Methods Data from the 2005 National HIV/AIDS and Reproductive Health Survey - an interviewer-administered nationally representative survey - were analyzed to identify individual, household and community factors that were significantly associated with utilization of maternal care services among 2148 women who had a baby during the five years preceding the survey. In view of the nested nature of the data, we used multilevel analytic methods and assessed state-level random effects. Results Approximately three-fifths (60.3% of the mothers used antenatal services at least once during their most recent pregnancy, while 43.5% had skilled attendants at delivery and 41.2% received postnatal care. There are commonalities and differences in the predictors of the three indicators of maternal health service utilization. Education is the only individual-level variable that is consistently a significant predictor of service utilization, while socio-economic level is a consistent significant predictor at the household level. At the community level, urban residence and community media saturation are consistently strong predictors. In contrast, some factors are significant in predicting one or more of the indicators of use but not for all. These inconsistent predictors include some individual level variables (the woman's age at the birth of the last child, ethnicity, the notion of ideal

    Full Text Available Background: Anemia in pregnancy is a serious condition, contributing to maternal mortality, morbidity and fetal morbidity and its prevalence varies between 35-100% in developing countries. This investigation is conducted to survey the correlation of maternal factors and the changes in hemoglobin in pregnant women. Method: In this study, 108 healthy pregnant women with gestational age of 10 to 14 weeks, chosen by cluster random sampling were included. The women were followed in three visits: at the end of the first, second and third trimester. In addition, correlation of Hb concentration with maternal factors including BMI, age parity, hyperemesis, gestational age, pregnancy interval and weight gain was investigated. Results: There was no significant correlation between BMI, parity, pregnancy interval, severe nausea and vomiting and also maternal age with hemoglobin level during pregnancy. Moreover, Multiple regression models showed that adequate maternal weight gain (P<0.009 and high hemoglobin (p<0.0001 in the first trimester were positive predictors and late iron supplementation was negative predictor of hemoglobin in pregnancy (P<0.006. Conclusion: Our data demonstrated that adequate maternal weight gain, high hemoglobin in the first trimester and also late iron supplementation could be as predictors in clinical settings in this query.

    Neonatal listeriosis is an exceptional disease in Northern Africa. Hence, protocols for maternal-fetal infection treatment include only a third generation cephalosporin and an aminoside. This protocol does not take into account the possibility of Listeria monocytogenes infection. We report a fatal case of neonatal listeriosis in Tunisia. The use of first antibiotics in maternal-foetal infection must be reconsidered when lacking sufficient bacteriological data and include systematically ampicillin in presumptive antibiotic protocols.

    To investigate the relationship between a child's weight and a broad range of family and maternal factors. Cross-sectional data from a population-based prospective study, collected between January 2004 and December 2005, for 329 children aged 6-13 years (192 healthy weight, 97 overweight and 40 obese) and their mothers (n=265) recruited from a paediatric hospital endocrinology department and eight randomly selected primary schools in Perth, Western Australia. Height, weight and body mass index (BMI) of children and mothers; demographic information; maternal depression, anxiety, stress and self-esteem; general family functioning; parenting style; and negative life events. In a multilevel model, maternal BMI and family structure (single-parent v two-parent families) were the only significant predictors of child BMI z scores. Childhood obesity is not associated with adverse maternal or family characteristics such as maternal depression, negative life events, poor general family functioning or ineffective parenting style. However, having an overweight mother and a single-parent (single-mother) family increases the likelihood of a child being overweight or obese.

  7. Maternal and family factors and child eating pathology: risk and protective relationships

    2014-01-01

    Background Previous studies have found associations between maternal and family factors and child eating disorder symptoms. However, it is not clear whether family factors predict eating disorder symptoms specifically, or relate to more general child psychopathology, of which eating disorder symptoms may be one component. This study aimed to identify maternal and family factors that may predict increases or decreases in child eating disorder symptoms over time, accounting for children’s body mass index z-scores and levels of general psychological distress. Methods Participants were 221 mother-child dyads from the Childhood Growth and Development Study, a prospective cohort study in Western Australia. Participants were assessed at baseline, 1-year follow-up and 2-year follow-up using interview and self-report measures. Children had a mean age of 10 years at baseline and 46% were male. Linear mixed models and generalised estimating equations were used to identify predictors of children’s eating disorder symptoms, with outcome variables including a global index of eating disorder psychopathology, levels of dietary restraint, levels of emotional eating, and the presence of loss of control (‘binge’) eating. Results Children of mothers with a current or past eating disorder reported significantly higher levels of global eating disorder symptoms and emotional eating than other children, and mothers with a current or past eating disorder reported significantly more concern about their children’s weight than other mothers. Maternal concern about child weight, rather than maternal eating disorder symptoms, was significant in predicting child eating disorder symptoms over time. Family exposure to stress and low maternal education were additional risk factors for eating disorder symptoms, whilst child-reported family satisfaction was a protective factor. Conclusions After adjusting for relevant confounding variables, maternal concern about child weight, children

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

    Full Text Available Background. Maternal anaemia is a worldwide public health problem affecting particularly developing countries. In Burkina Faso, little data is available for rural areas. This study aimed to determine the prevalence of maternal anaemia and the risk factors associated with it in the rural health district of Hounde in Burkina Faso but also to define better control measures of maternal anaemia. Methods. This cross-sectional study conducted in 2010 had a sample of 3,140 pregnant women attending antenatal care in all the 18 primary health care facilities of the district. The women’s characteristics and their knowledge about contraceptives and sexually transmitted infections (STI were collected. Also, physical and gynaecological examination, completed by vaginal, cervix, blood, and stool samplings, were collected. Results. A prevalence of 63.1% was recorded for maternal anaemia. Geophagy rate was 16.3% and vitamin A deficiency 69.3%. In addition, anaemia was independently associated with low education, low brachial perimeter, geophagy, and primigravida. But no statically significant relationship was found between maternal anaemia and infectious diseases or vitamin A deficiency. Conclusion. The magnitude of maternal anaemia was found to be higher in rural Hounde health district and should be addressed by adequate policy including education and the fight against malnutrition.

    To examine the influence of maternal lymphocyte factors on the immune responses in offspring in early life, antibody production in neonates born to either normal or lymphocyte-deficient mothers was analyzed. Recombination activating gene (Rag)-2(+/-) mouse neonates born to Rag-2(+/+), Rag-2(+/-)or Rag-2(-/-)mothers were injected with goat anti-mouse IgD antiserum, and IgE and IgG(1) production was evaluated. The levels of IgE and IgG(1) were higher in the pups born to Rag-2(+/+)and Rag-2(+/-) dams than to lymphocyte-deficient Rag-2(-/-) dams. The enhanced antibody production in the former compared with the latter neonates was also found following immunization with ovalbumin or TNP-Ficoll. Thus, the presence of maternal lymphocyte factors was suggested in neonates that augmented antigen-specific antibody production in both T cell-dependent and -independent pathways. A reduction in antibody production was observed in normal neonates when they were foster-nursed by Rag-2(-/-) mothers. Thus, the maternal lymphocyte factors enhancing the immune responses in newborns were shown to be present in breast-milk.

    Full Text Available BACKGROUND: Women continue to die unnecessarily during or after pregnancy in the developed world. The aim of this analysis was to compare women with severe maternal morbidities who survived with those who died, to quantify the risk associated with identified factors to inform policy and practice to improve survival. METHODS AND FINDINGS: We conducted a national cohort analysis using data from two sources obtained between 2003 and 2009: the Centre for Maternal and Child Enquiries maternal deaths database and the United Kingdom Obstetric Surveillance System database. Included women had eclampsia, antenatal pulmonary embolism, amniotic fluid embolism, acute fatty liver of pregnancy or antenatal stroke. These conditions were chosen as major causes of maternal mortality and morbidity about which data were available through both sources, and include 42% of direct maternal deaths over the study period. Rates, risk ratios, crude and adjusted odd ratios were used to investigate risks factors for maternal death. Multiple imputation and sensitivity analysis were used to handle missing data. We identified 476 women who survived and 100 women who died. Maternal death was associated with older age (35+ years aOR 2.36, 95%CI 1.22-4.56, black ethnicity (aOR 2.38, 95%CI 1.15-4.92, and unemployed, routine or manual occupation (aOR 2.19, 95%CI 1.03-4.68. An association was also observed with obesity (BMI≥30 kg/m(2 aOR 2.73, 95%CI 1.15-6.46. CONCLUSIONS: Ongoing high quality national surveillance programmes have an important place in addressing challenges in maternal health and care. There is a place for action to reverse the rising trends in maternal age at childbirth, and to reduce the burden of obesity in pregnancy, as well as ongoing recognition of the impact of older maternal age on the risks of pregnancy. Development and evaluation of services to mitigate the risk of dying associated with black ethnicity and lower socioeconomic status is also essential.

    2016-06-01

    Studies have reported that advanced maternal age is a risk factor for congenital heart disease (CHD), but none of these have been performed in the United Kingdom. Currently, women in the United Kingdom are not referred for specialist fetal echocardiography based on maternal age alone. The aim of this study is to examine the association between maternal age at delivery and CHD prevalence in the North of England. Singleton cases of CHD notified to the Northern Congenital Abnormality Survey and born between January 1, 1998, to December 31, 2013, were included. Cases with chromosomal anomalies were excluded. The relative risk (RR) of CHD according to maternal age at delivery was estimated using Poisson regression. There were 4024 singleton cases of nonchromosomal CHD, giving a prevalence of 8.1 (95% confidence interval [CI], 7.8-8.3) per 1000 live and stillbirths. There was no association between maternal age at delivery and CHD prevalence (p = 0.97), with no evidence of an increased risk of CHD in mothers aged ≥35 compared to aged 25 to 29 (RR = 0.99; 95% CI, 0.89-1.09). There were no significant associations between maternal age at delivery and severity III CHD (p = 0.84), severity II CHD (p = 0.74), or severity I CHD (p = 0.66), although there was a slight increased risk of severity I CHD in mothers aged ≥35 (RR = 1.27; 95% CI, 0.83-1.95). We found little evidence that advanced maternal age is a risk factor for CHD. There is no evidence that women in the United Kingdom should be referred for specialist prenatal cardiac screening based on their age.

    Maternal and paternal factors create considerable obstacles to the elimination of congenital syphilis (CS). A clear understanding of maternal and paternal factors is important in order to define interventions in every community. This study aimed to investigate the maternal and paternal factors associated with CS. A prospective cohort study was conducted from April 25, 2007 to October 31, 2012 at the Shenzhen Center for Chronic Disease Control and Prevention (SCCDC) in China. We screened 279,334 pregnant women and identified 838 women with syphilis. Finally, a total of 360 women with syphilis were included for analysis. At the end of follow-up, 34 infants [9.4 %, 95 % confidence interval (CI): 6.8-12.9 %] were diagnosed with CS. Following adjustment for confounders, maternal history of syphilis [adjusted risk ratio (aRR) = 0.21], prenatal care (aRR = 0.12), and complete treatment (aRR = 0.22) reduced the risk of infants being infected. Every two-fold increase of titer of non-treponemal antibodies (aRR = 1.88), early stage of syphilis (aRR = 9.59), a shorter length of time between the end of the first treatment to childbirth (aRR = 5.39), and every week of delay in treatment (aRR = 2.25) for maternal syphilis as well as paternal history of cocaine use (aRR = 6.28) and positive (aRR = 3.30) or unknown (aRR = 2.79) status of syphilis increased the risk of infants being infected. CS also increased the risk (aRR = 8.02) of neonatal death. Maternal and paternal factors constituted two separate profiles associated with CS. To become more effective, future strategies for the prevention of CS should be targeted to each profile.

    Full Text Available Objective. We investigated the possible factors related to the birth weight (BW using the Japanese perinatal database. Methods. The live infants born at 37 to 41 weeks of gestation were enrolled in this study. Cases with diabetic pregnancy, preeclampsia, an anomalous fetus, and a fetus with chromosomal abnormalities were excluded. A multiple regression analysis for confounding factors and an analysis of covariance (ANCOVA for comparing the BW in 2006 and 2010 were used for the statistical analysis. Results. The BW significantly decreased from 2950.8 g in 2006 (n=27,723 to 2937.5 g in 2010 (n=38,008 in the overall population, and this decrease was similar for male and female neonates. All confounding factors, except for the mode of delivery, affected the BW. Primiparity, smoking, and a female gender were related to the decrease in BW, whereas maternal age, maternal height, weight gain during pregnancy, BMI, the use of in vitro fertilization, induction of labor, and gestational duration were related to an increased BW. The ANCOVA showed that no significant change of the BW was seen between 2006 and 2010 (the difference was 2.164 g, P=0.414. Conclusion. The gestational duration is the most important factor affecting the BW in singleton term infants.

    China bears a large burden of global maternal mortality, and the largest burden of maternal deaths in China is in poor western provinces. This study aimed to investigate the trends in maternal mortality and its associated factors in Guizhou province of western China between 1996 and 2009, and examine differences between minority and non-minority counties. A population-based, longitudinal, retrospective study was performed in a poor western province of China with a considerably large ethnic minority population. All 86 counties/districts of Guizhou were included with population at county, township and village level. Maternal mortality data were collected from routine reporting database of Guizhou Provincial Health Bureau. Trend and comparative analyses and multivariate linear regression analyses were performed using SPSS 17.0. Maternal mortality ratio (MMR) and its change over time, differences between ethnic groups were analyzed. A declining trend in maternal mortality and rising trend in hospital delivery in Guizhou was observed; ethnic differences between two ethnic groups persisted. The reduction in maternal mortality between 1996 and 2009 was related with increased gross domestic product, decreased male illiteracy rate, and increased hospital delivery rate. We found the declining trends in maternal mortality in Guizhou with persisting ethnic differences. The declining trends are related with economic development, hospital delivery and male illiteracy. Effective health education on maternal health is urgently needed for the minority groups, and basic education for the new generation should be enhanced to eradicate the illiteracy.

    Recent evidence suggests that sexually antagonistic genetic factors in the maternal line promote homosexuality in men and fecundity in female relatives. However, it is not clear if and how these genetic factors are phenotypically expressed to simultaneously induce homosexuality in men and increased fecundity in their mothers and maternal aunts. The aim of the present study was to investigate the phenotypic expression of genetic factors that could explain increased fecundity in the putative female carriers. Using a questionnaire-based approach, which included also the Big Five Questionnaire personality inventory based on the Big Five theory, we investigated fecundity in 161 female European subjects and scrutinized possible influences, including physiological, behavioral, and personality factors. We compared 61 female probands who were either mothers or maternal aunts of homosexual men. One hundred females who were mothers or aunts of heterosexual men were used as controls. Personality traits, retrospective physiological and clinical data, behavior and opinions on fecundity-related issues were assessed and analyzed to illustrate possible effects on fecundity between probands and control females. Our analysis showed that both mothers and maternal aunts of homosexual men show increased fecundity compared with corresponding maternal female relatives of heterosexual men. A two-step statistical analysis, which was based on t-tests and multiple logistic regression analysis, showed that mothers and maternal aunts of homosexual men (i) had fewer gynecological disorders; (ii) had fewer complicated pregnancies; (iii) had less interest in having children; (iv) placed less emphasis on romantic love within couples; (v) placed less importance on their social life; (vi) showed reduced family stability; (vii) were more extraverted; and (viii) had divorced or separated from their spouses more frequently. Our findings are based on a small sample and would benefit from a larger

    Background Scarce evidence is available on the potential cardiovascular abnormalities associated with some common gestational complications. We aimed to analyze the potential maternal cardiac alterations related to gestational complications, including body mass index (BMI) >25 kg/m2, gaining excessive weight, or developing antenatal depression. Methods The design of this study was a secondary analysis of a randomized controlled trial. Echocardiography was performed to assess cardiovascular indicators of maternal hemodynamic, cardiac remodeling and left ventricular (LV) function in 59 sedentary pregnant women at 20 and 34 weeks of gestation. Results Starting pregnancy with a BMI >25 kg/m2, gaining excessive weight, and developing antenatal depression had no cardiovascular impact on maternal health (P value >0.002). Depressed women were more likely to exceed weight gain recommendations than non-depressed women (P value <0.002). Conclusions The evaluated gestational complications seem not to induce cardiovascular alterations in hemodynamic, remodeling and LV function indicators. However, developing antenatal depression increases the risk of an excessive weight gain. This finding is potentially important because excessive weight gain during pregnancy associates with a higher risk of cardiovascular diseases (CVD) later in life. PMID:27500154

    Knowledge on the factors associated with severe maternal morbidity enables a better understanding of the problem and serves as a foundation for the development of an effective preventive strategy. However, various definitions of severe maternal morbidity have been applied, leading to inconsistencies between studies. The objective of this study was to identify the sociodemographic characteristics, medical and gynaecological history, past and present obstetric performance and the provision of health care services as associated factors for severe maternal morbidity in Kelantan, Malaysia. A comparative cross-sectional study was conducted in two tertiary referral hospitals in 2014. Postpartum women with severe morbidity and without severe morbidity who fulfilled the inclusion and exclusion criteria were eligible as cases and controls, respectively. The study population included all postpartum women regardless of their age. Pregnancy at less than 22 weeks of gestation, more than 42 days after the termination of pregnancy and non-Malaysian citizens were excluded. Consecutive sampling was applied for the selection of cases and for each case identified, one unmatched control from the same hospital was selected using computer-based simple random sampling. Simple and multiple logistic regressions were performed using Stata Intercooled version 11.0. A total of 23,422 pregnant women were admitted to these hospitals in 2014 and 395 women with severe maternal morbidity were identified, of which 353 were eligible as cases. An age of 35 or more years old [Adj. OR (95 % CI): 2.6 (1.67, 4.07)], women with past pregnancy complications [Adj. OR (95 % CI): 1.7 (1.00, 2.79)], underwent caesarean section deliveries [Adj. OR (95 % CI): 6.8 (4.68, 10.01)], preterm delivery [Adj. OR (95 % CI): 3.4 (1.87, 6.32)] and referral to tertiary centres [Adj. OR (95 % CI): 2.7 (1.87, 3.97)] were significant associated factors for severe maternal morbidity. Our study suggests the enhanced

    Marie Cecilie Paasche Roland

    Full Text Available INTRODUCTION: Maternal nutritional and metabolic factors influence the developmental environment of the fetus. Virtually any nutritional factor in the maternal blood has to pass the placental membranes to reach the fetal blood. Placental weight is a commonly used measure to summarize placental growth and function. Placental weight is an independent determinant of fetal growth and birthweight and modifies the associations between maternal metabolic factors and fetal growth. We hypothesized that maternal factors known to be related to fetal growth, newborn size and body composition are determinants of placental weight and that effects of maternal metabolic factors on placental weight differ between the genders. METHODS: The STORK study is a prospective longitudinal study including 1031 healthy pregnant women of Scandinavian heritage with singleton pregnancies. Maternal determinants (parity, body mass index, gestational weight gain and fasting plasma glucose of placental weight were explored by linear regression models, stratified by fetal sex. RESULTS: Parity, maternal BMI, gestational weight gain and fasting glucose had positive effects on placental weight. There was a sex specific effect in these associations. Fasting glucose was significantly associated with placental weight in females but not in males. CONCLUSION: Maternal factors known to influence fetal growth, birthweight and neonatal body composition are determinants of placental weight. The effect of maternal factors on placental weight is influenced by sex as illustrated in the relation between maternal glucose and placental weight.

    Full Text Available Abstract Access to timely and quality maternal health care remains to be a major development challenge in many developing economies particularly in Kenya. The countrys system of providing maternal health care also continue to be anchored on conventional methods of physical presence of the patient and the doctor in a hospital setup. The countrys ICT and health policies also place very little emphasis on the use of these platforms. This study therefore sought to establish the factors affecting the adoption of mHealth by focusing on maternal health in Nakuru Provincial General Hospital. Objectives of the study were to determine the extent to knowledge and awareness affects the adoption of mHealth in maternal health care at Nakuru PGH to identify the government policies affecting the adoption of mHealth in maternal health care at Nakuru PGH to assess how access to technology affects the adoption of mHealth in maternal healthcare to establish the effects of ICT infrastructure on the adoption of mHealth in maternal health care and to identify the cost aspects affecting the adoption of mHealth in maternal health care at Nakuru Provincial General Hospital. It is envisaged that the study could provide useful information on the adoption of mHealth in managing maternal health care in Nakuru Provincial General Hospital. Descriptive survey research design will be used where all the medical staff and patients of Nakuru Provincial General Hospital was surveyed. The study population therefore was made up of 24 medical staff and 3460 mothers visiting the antenatal clinic selected using clustered random sampling technique. The main instrument for primary data collection was the questionnaire. Data analysis was then done using both descriptive and inferential statistics. Descriptive statistics to be used include frequency counts percentages and measures of central tendency. Inferential statistics on the other hand include t-test analysis and spearman correlation

    Full Text Available Background/Aim. Maternal morbidity is defined as any condition that is attributed to or aggravated by pregnancy and childbirth that has a negative impact on the woman's wellbeing. In recent years, a growing trend of cesarean section rates can be seen throughout the world. The aim of this study was to assess factors that might have major impact on maternal adverse outcome in women with two or more previous cesarean sections. Methods. This retrospective study included women with single term pregnancy after two or more cesarean deliveries in a 10-year period (2004−2013 in the University Clinic “Narodni front” in Belgrade, Serbia. Medical records were reviewed for clinical data for maternal intraoperative and early postoperative complications regarding gestational age at delivery, the number of previous cesarean sections and mode of surgery (elective or emergency. Results. A total of 551 patients were included in the study. At 37 completed weeks delivered 14.1%, at 38 delivered 45.2% and at 39 completed weeks 40.7% patients. Women younger than 35 years more often delivered after 39 completed weeks compared with those over 35 years (69.2% vs 30.8%, p < 0.05. The overall rate of maternal complications in the study group was 16.5% with no statistical difference by gestational age at delivery. The overall rate of maternal adverse outcome was significantly less in the patients with three as compared with those with four or more cesareans (10.4% vs 66.7%, p < 0.05. There was a statistically significant difference between these groups of women regarding complications: scar dehiscence, the presence of adhesions, blood transfusion and admission in intensive care unit. Elective cesarean delivery was with less maternal complications compared with emergency cesarean deliveries (12.9% vs 27.3%, p < 0.05. Conclusion. Termination of pregnancy before completed 39 weeks does not decrease maternal morbidity. The major impact on maternal complications has the

    Newborn diseases increase neonatal mortality rates, so a literature review was conducted to establish the risk factors related to maternal and peripartum morbidity affecting the newborn. We searched the following electronic databases: Cumed, EBSCO, LILACS, IBECS and PubMed/MEDLINE. We used specific terms and Boolean operators in Spanish, Portuguese and English. We included longitudinal and cross-sectional descriptive studies, as well as case-control and cohort studies, systematic reviews and meta-analysis, spanning from 2010 to 2015 that responded the topic of interest. The included studies show that multiple maternal and perinatal conditions are risk factors for significant increase of neonatal morbidity, which are described in this narrative review.

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

    To establish normal ranges of maternal placental growth factor (PlGF), soluble fms-like tyrosine kinase-1 (sFlt-1) and sFlt-1/PlGF ratio at 32-41 weeks' gestation and to evaluate the influence of maternal characteristics, and of fetoplacental Doppler. Serum levels of PlGF, sFlt-1 and sFlt-1/PlGF ratio were measured in 300 noncomplicated pregnancies (30 at each gestational week between 32 and 41). Quantile regression analysis was used to derive gestational age (GA)-adjusted normal ranges, and to account for characteristics that might influence serum levels. The relationship with Doppler indices was tested, including umbilical artery pulsatility index and middle cerebral artery pulsatility index. PlGF decreased with GA from 32 weeks, while sFlt-1 and sFlt-1/PlGF ratio increased steadily. None of the factors evaluated showed any significant influence on the levels of angiogenic factors. PlGF multiple of the median significantly correlated with mean uterine artery Doppler (R -0.17; p = 0.029). In normal pregnancies during the third trimester, serum PlGF decreases, sFlt-1 increases and sFlt-1/PlGF ratio increases with GA. Angiogenic factor levels needed no adjustment for factors such as smoking, body mass index, blood pressure or parity.

    This report describes an exploratory population-based study of maternal and perinatal risk factors for childhood leukemia in Sweden. The Swedish National Cancer Registry ascertained 411 cases in successive birth cohorts from 1973 through 1984 recorded in the Swedish Medical Birth Registry. Using the latter, we matched five controls without cancer to each case by sex and month and year of birth. Mothers of children with leukemia were more likely to have been exposed to nitrous oxide anesthesia during delivery than mothers of controls (odds ratio (OR) = 1.3; 95% confidence interval (CI) = 1.0, 1.6). Children with leukemia were more likely than controls to have Down's syndrome (OR = 32.5; 95% CI = 7.3, 144.0) or cleft lip or cleft palate (OR = 5.0; 95% CI = 1.0, 24.8); to have had a diagnosis associated with difficult labor but unspecified complications (OR = 4.5; 95% CI = 1.1, 18.2) or with other conditions of the fetus or newborn (OR = 1.5; 95% CI = 1.1, 2.1), specifically, uncomplicated physiological jaundice (OR = 1.9; 95% CI = 1.2, 2.9); or to have received supplemental oxygen (OR = 2.6; 95% CI = 1.3, 1.3, 4.9). Because multiple potential risk factors were analyzed in this study, future studies need to check these findings. The authors did not confirm the previously reported higher risks for childhood leukemia associated with being male, having a high birth weight, or being born to a woman of advanced maternal age.

    Full Text Available OBJECTIVE: tthis study aimed to investigate the incidence of premature rupture of fetal membranes in preterm singleton pregnancies and its association with sociodemographic factors and maternal self-reported genitourinary infections. METHODS: this was a population-based cross-sectional study, which included all mothers of newborns of singleton deliveries that occurred in 2010, with birth weight > 500 grams, who resided in the city of Rio Grande. Women were interviewed in the two maternity hospitals. Cases were women who had lost amniotic fluid before hospitalization and whose gestational age was less than 37 weeks. Statistical analysis was performed by levels to control for confounding factors using Poisson regression. RESULTS: of the 2,244 women eligible for the study, 3.1% had preterm premature rupture of fetal membranes, which was more frequent, after adjustment, in women of lower socioeconomic status, (prevalence ratio [PR] = 1.94, with lower level of schooling (PR = 2.43, age > 29 years (PR = 2.49, and smokers (PR = 2.04. It was also associated with threatened miscarriage (PR = 1.68 and preterm labor, (PR = 3.40. There was no association with maternal urinary tract infection or presence of genital discharge. CONCLUSIONS: the outcome was more common in puerperal women with lower level of schooling, lower socioeconomic status, older, and smokers, as well as those with a history of threatened miscarriage and premature labor. These factors should be considered in the prevention, diagnosis, and therapy approach.

    Risk factors for child obesity may be influenced by family environment, including maternal depression, family structure, and parenting quality. We tested a path model in which maternal depression and single parent status are associated with parenting quality, which relates to three risk factors for child obesity: diet, leisure, and sedentary behavior. Participants included 4,601 5th-grade children and their primary caregivers who participated in the Healthy Passages study. Results showed that associations of maternal depression and single parenthood with child BMI are mediated by parenting quality and its relation to children's leisure activity and sedentary behavior. Interventions for child obesity may be more successful if they target family environment, particularly parenting quality and its impact on children's active and sedentary behaviors.

    Full Text Available La lactancia materna es un hábito ligado íntimamente a la supervivencia de la especie humana desde tiempo inmemorial. Tras una etapa de abandono masivo a mediados del siglo XX, estamos asistiendo a una recuperación de este hábito, especialmente en el mundo denominado "desarrollado", promovida desde las instituciones de salud ante la evidencia científica. La superioridad de la lactancia materna frente a la lactancia artificial es indiscutible y la evidencia científica así lo pone de manifiesto. La lactancia materna es un factor positivo de salud para la madre y para el niño. Por tanto la promoción y recuperación de este hábito es algo más que una moda o una tendencia: es un factor indiscutible de salud materno-infantil. El Gobierno de Navarra mediante Orden Foral de 28 de enero de 2004, se ha unido a las múltiples iniciativas administrativas que están surgiendo en nuestro entorno para la promoción de la lactancia materna, mediante la constitución de la Comisión Asesora Técnica para la Promoción de la Lactancia Materna en Navarra.Maternal breastfeeding is a habit that has been closely linked to the survival of the human species since time immemorial. Following a stage when it was massively abandoned in the mid-XX century, we are now witnessing a recovery of this habit, especially in the so-called "developed" world, promoted by the health institutions in light of the scientific evidence. The superiority of maternal breastfeeding over artificial feeding is beyond dispute as the scientific evidence makes clear. Maternal breastfeeding is a positive factor for the health of the mother and for the child. Hence the promotion and recovery of this habit is more than just a fashion or tendency: it is an incontrovertible factor in maternal-child health. Through the Foral Order of January 28th 2004, the government of Navarre has brought together the numerous administrative initiatives that are emerging in our province for the promotion of

    Background The high rate of maternal mortality reported in The Gambia is influenced by many factors, such as difficulties in accessing quality healthcare and facilities. In addition, socio-cultural practices in rural areas may limit the resources available to pregnant women, resulting in adverse health consequences. The aim of this study is to depict the gender dynamics in a rural Gambian context by exploring the social and cultural factors affecting maternal health. Methods and Findings Five focus group discussions that included 50 participants (aged 15–30 years, with at least one child) and six in-depth interviews with traditional birth attendants were conducted to explore perceptions of maternal health issues among rural women. The discussion was facilitated by guides focusing on issues such as how the women perceived their own physical health during pregnancy, difficulties in keeping themselves healthy, and health-related problems during pregnancy and delivery. The data resulting from the discussion was transcribed verbatim and investigated using a qualitative thematic analysis. In general, rural Gambian women did not enjoy privileges in their households when they were pregnant. The duties expected of them required pregnant women to endure heavy workloads, with limited opportunities for sick leave and almost nonexistent resources to access prenatal care. The division of labor between men and women in the household was such that women often engaged in non-remunerable field work with few economic resources, and their household duties during pregnancy were not alleviated by either their husbands or the other members of polygamous households. At the time of delivery, the decision to receive care by trained personnel was often beyond the women’s control, resulting in birth-related complications. Conclusions Our findings suggest that despite women’s multiple roles in the household, their positions are quite unfavorable. The high maternal morbidity and mortality

    Due to the influx of Latino immigration in the United States, health care services are faced with the challenge of meeting the needs of this growing population. In this qualitative study, we explored Latina immigrants' experiences with maternal health care services. We found that despite enduring language barriers and problems, Spanish-speaking women expressed satisfaction with their care. Factors influencing women's perceptions of care included sociocultural norms (respeto, personalismo, and familismo), previous experiences with care in their countries of origin, having healthy babies, and knowledge about entitlement to interpreter services. We offer recommendations for public health practice and research.

    To examine placental growth factor (PlGF) levels in first trimester maternal serum in trisomy 21 pregnancies and to investigate the potential value of PlGF in a first trimester screening test. First trimester maternal serum from 70 trisomy 21 cases and 375 euploid controls were retrospectively analyzed for PlGF using a DELFIA Xpress immunoassay platform. Results were expressed as multiples of medians (MoM) for comparison. PlGF levels were significantly decreased in pregnancies with trisomy 21, 0.76 MoM versus 0.98 MoM in controls. Inclusion of PlGF into the first trimester combined test [maternal age, pregnancy associated plasma protein-A (PAPP-A), free-beta human chorionic gonadotrophin (beta-hCG) and nuchal translucency] would increase the detection rate by 0.5% at a 5% false positive rate. PlGF at 11 weeks to 13 weeks 6 days has the potential to be included as a marker for the detection of pregnancies with trisomy 21.

    Background Maternal obesity represents a risk factor for pregnancy-related complications. Glucocorticoids are known to promote obesity in adults. Methods We evaluated maternal and fetal metabolic changes during and after three weekly courses of betamethasone (BM) administered to pregnant baboons (Papio spp.) at doses equivalent to those given to pregnant women. Results BM administration during the second half of pregnancy increased maternal weight, but neither maternal food intake nor fetal weight, as assessed at the end of gestation. BM increased maternal serum glucose concentration, IGF-I:IGFBP-3 ratio, and serum leptin during treatment (normalized by 17, 35, and 45 days post-treatment respectively for each parameter). Maternal and fetal serum leptin concentrations did not differ between groups at the end of gestation. Conclusion Prolonged maternal hyperleptinemia caused by BM administration in the second half of gestation did not change fetal metabolic parameters measured and placental leptin distribution at the end of gestation.

    Full Text Available Abstract Background An interaction between genetic susceptibility and environmental factors is thought to be involved in the aetiology of type 1 diabetes. The aim of this study was to investigate maternal and neonatal risk factors for type 1 diabetes in children under 15 years old in Grampian, Scotland. Methods A matched case-control study was conducted by record linkage. Cases (n = 361 were children born in Aberdeen Maternity Hospital from 1972 to 2002, inclusive, who developed type 1 diabetes, identified from the Scottish Study Group for the Care of Diabetes in the Young Register. Controls (n = 1083 were randomly selected from the Aberdeen Maternity Neonatal Databank, matched by year of birth. Exposure data were obtained from the Aberdeen Maternity Neonatal Databank. Conditional logistic regression was used to evaluate the association between various maternal and neonatal factors and the risk of type 1 diabetes. Results There was no evidence of statistically significant associations between type 1 diabetes and maternal age, maternal body mass index, previous abortions, pre-eclampsia, amniocentesis, maternal deprivation, use of syntocinon, mode of delivery, antepartum haemorrhage, baby's sex, gestational age at birth, birth order, birth weight, jaundice, phototherapy, breast feeding, admission to neonatal unit and Apgar score (P > 0.05. A significantly decreased risk of type 1 diabetes was observed in children whose mothers smoked at the booking appointment compared to those whose mothers did not, with an adjusted OR of 0.67, 95% CI (0.46, 0.99. Conclusions This case-control study found limited evidence of a reduced risk of the development of type 1 diabetes in children whose mothers smoked, compared to children whose mothers did not. No evidence was found of a significant association between other maternal and neonatal factors and childhood type 1 diabetes.

    The aim of this study was to explore Chinese women's perceptions of maternal role competence and factors contributing to maternal role competence during early motherhood. Developing a sense of competence and satisfaction in the maternal role are considered critical components in maternal adaptation, which have a significant impact on parenting behaviours and the psychosocial development of the child. However, qualitative studies that address maternal role competence are limited in the Chinese population. This was an exploratory descriptive study. A purposive sample of 26 Chinese primiparous mothers participated in a childbirth psychoeducation programme and was interviewed at six weeks postpartum. Data were analysed using content analysis. Women perceived a competent mother as being able to make a commitment to caring for the physical and emotional well-being of child, while cultivating appropriate values for childhood. Personal knowledge and experience of infant care, success in breastfeeding, infant's well-being, availability of social support and contradictory information from various sources were major factors affecting maternal role competency. The findings highlight the importance of understanding Chinese cultural attitudes to childrearing and maternal role competence. New Chinese mothers need information on child care, positive experiences of infant care, social support and consistent information to enhance their maternal role competency. Recommendations are made for Chinese culturally specific guidelines and healthcare delivery interventions to enhance maternal role competence in early motherhood. Nursing and midwifery care should always take into account the cultural beliefs and enable adaptation of traditional postpartum practices. Providing consistent information and positive experience on parenting skills and infant behaviour as well as enhancing effective coping strategies could strengthen Chinese women's maternal role competency. © 2011 Blackwell

    Full Text Available Fetuses with neural tube defects (NTDs may be associated with syndromes, disorders, and maternal and fetal risk factors. This article provides a comprehensive review of syndromes, disorders, and maternal and fetal risk factors associated with NTDs, such as omphalocele, OEIS (omphalocele-exstrophy-imperforate anus-spinal defects complex, pentalogy of Cantrell, amniotic band sequence, limb-body wall complex, Meckel syndrome, Joubert syndrome, skeletal dysplasia, diabetic embryopathy, and single nucleotide polymorphisms in genes of glucose metabolism. NTDs associated with syndromes, disorders, and maternal and fetal risk factors are a rare but important cause of NTDs. The recurrence risk and the preventive effect of maternal folic acid intake in NTDs associated with syndromes, disorders and maternal risk factors may be different from those of nonsyndromic multi facto rial NTDs. Perinatal identification of NTDs should alert the clinician to the syndromes, disorders, and maternal and fetal risk factors associated with NTDs, and prompt a thorough etiologic investigation and genetic counseling.

    Full Text Available ABSTRACT: CONTEXT AND OBJECTIVE: The disability associated with maternal common mental disorders (CMDs is among the possible explanations for the association between chronic childhood malnutrition and CMDs. CMDs may impair the mother's ability to perform her role, particularly in deprived environments. The present study aimed to evaluate whether disability relating to CMDs could be part of the pathway of the association between childhood malnutrition and maternal CMDs. DESIGN AND SETTING: Cross-sectional study conducted in two institutions: one for malnourished children and another for eutrophic children living in a low-income community in the state of Alagoas, Brazil. METHOD: The cases consisted of 55 malnourished children aged from 12 to 60 months who were attending a nutritional rehabilitation center, with height-for-age z-scores < 2. The controls were 70 eutrophic children of the same age who were attending a day care center in the same area as the cases. The Self-Report Questionnaire made it possible to identify likely cases of maternal CMD. The Sheehan Disability Scale enabled evaluation of the associated disability. RESULTS: Chronic childhood malnutrition was significantly associated with maternal disability relating to CMDs (OR = 2.28; 95% CI: 1.02-5.1. The best logistic regression model using chronic childhood malnutrition as the dependent variable included the following independent variables: higher number of people living in the household; absence of the biological father from the household; and maternal disability relating to CMDs. CONCLUSIONS: If confirmed, the association between chronic childhood malnutrition and maternal disability relating to CMDs may be useful in helping to identify the causal chain between childhood malnutrition and maternal CMDs and to indicate environmental risk factors associated with chronic childhood malnutrition.

    Full Text Available The objective of this study was to determine the prevalence of maternal group B Streptococcal (GBS colonization and compare risk factor data related to GBS colonization. A prospective surveillance study of 598 pregnant women was conducted in two socioeconomically diverse maternity hospitals in Ribeirão Preto, Brazil between June and October 1999. Swabs from the lower vagina were obtained between 35 and 37 weeks gestation and cultured on selective media. Risk factor data were obtained by patient interview and chart review. The overall maternal GBS colonization prevalence rate was 17.9%. There was no association of GBS colonization with maternity hospital and no association of GBS colonization with previously identified risk factors, such as age, race, martial status, maternal education, parity, smoking, or alcohol use. There is a relatively high prevalence of maternal GBS colonization in this Brazilian population, although previously-identified-risk factors were not found to be important. This study provides baseline data for the creation of community-based GBS disease prevention protocols.

Rural Guinea-Bissau. More than 15,000 women living in 100 clusters were visited at six-monthly intervals over a period of more than six years. A total of 10,931 pregnancies were registered prospectively; 85 of these pregnancies resulted in maternal or late maternal death. Maternal mortality ratio. In the rural areas of Guinea-Bissau, we conducted a prospective survey of women in the fertile age range. More than 15,000 women living in 100 clusters were visited at 6-monthly intervals over a period of more than six years. An analysis of demographic, environmental and obstetric risk factors for maternal death was performed based on 10,931 prospectively registered pregnancies; 85 of these pregnancies resulted in maternal or late maternal death. In the adjusted model maternal mortality ratio increased with increasing distance from the regional hospital (OR>25 km = 7.4 [95% CI: 1.6-132]). Multiple pregnancy was found to increase the risk of maternal death (OR = 3.4 [95% CI: 1.3-7.5]). The risk of subsequent maternal death was increased if the fetus was stillborn (OR = 5.3 [95% CI: 2.8-9.4]). Women living in the region of Gabu had higher mortality than those living in Biombo (OR = 2.5 [95% CI: 1.3-5.1]). No category of age or parity were associated with an increased risk of maternal mortality. Predictive values did not exceed 3% for any of the significant risk factors. For the purpose of reducing maternal mortality, the screening approach of antenatal care is of limited value. Age and parity should not be used routinely as selection criteria for transfer of otherwise healthy pregnant women to higher-level health institutions. Twin pregnancy seems to be the only operational risk factor identified in this study. Stillbirth is associated with an increased risk of maternal death. Regional

    Full Text Available Introduction: Birth weight is recommended as one of the twelve global indicators for monitoring the health of the community and is an important determinant of adverse perinatal and neonatal events. LBW infant carries five times higher risk of dying in the neonatal period and three times more in infancy. Aims and Objectives: To estimate the incidence of LBW and impact of various maternal and biosocial factors on the incidence of LBW neonates in the study population. Material and methods: This prospective observational study was carried out in Princess Esra hospital, a tertiary care hospital in south India, over a period of six months. All consecutive LBW (single ton neonates admitted to the neonatal intensive care unit were enrolled, while those born of multiple gestation and those with major congenital malformations were excluded. Results: A total of 300 neonates were included in the present study out of which 150 were LBW and 150 weighed ≥2500 gm. Higher maternal weight (>60kgs had low incidence of LBW neonates (p value-0.03. Illiterate women had a remarkably higher incidence of LBW babies (p value-0.001. In primigravida incidence of LBW was 61.2%. Higher incidence of LBW was seen in mothers with oligo hydramnio’s. Conclusions: This study showed that maternal age, weight, literacy level and parity have a significant influence on the incidence of LBW. Incidence of LBW neonate in the study was 50%. Risk of having LBW neonates was higher in primigravida. There was a significant association between LBW with oligo hydramnio’s and female gender.

    Full Text Available BACKGROUND: The aims of this study were to 1 determine the distinct patterns of body mass index (BMI trajectories in Japanese children, and 2 elucidate the maternal factors during pregnancy, which contribute to the determination of those patterns. METHODOLOGY/PRINCIPAL FINDINGS: All of the children (1,644 individuals born in Koshu City, Japan, between 1991 and 1998 were followed in a longitudinal study exploring the subjects' BMI. The BMI was calculated 11 times for each child between birth and 12 years of age. Exploratory latent class growth analyses were conducted to identify trajectory patterns of the BMI z-scores. The distribution of BMI trajectories were best characterized by a five-group model for boys and a six-group model for girls. The groups were named "stable thin," "stable average," "stable high average," "progressive overweight," and "progressive obesity" in both sexes; girls were allocated to an additional group called "progressive average." Multinomial logistic regression found that maternal weight, smoking, and skipping breakfast during pregnancy were associated with children included in the progressive obesity pattern rather than the stable average pattern. These associations were stronger for boys than for girls. CONCLUSIONS/SIGNIFICANCE: Multiple developmental patterns in Japanese boys and girls were identified, some of which have not been identified in Western countries. Maternal BMI and some unfavorable behaviors during early pregnancy may impact a child's pattern of body mass development. Further studies to explain the gender and regional differences that were identified are warranted, as these may be important for early life prevention of weight-associated health problems.

  3. Maternal obesity is a risk factor for orofacial clefts: a meta-analysis.

    Orofacial clefts are the most prevalent birth defects that affect craniofacial structures and implicate genetic and environmental factors in their aetiology. Maternal metabolic state and nutrition have been related to these and other structural malformations, and studies of maternal obesity before pregnancy have shown controversial results about its association with the risk of orofacial clefts in their offspring. Our aim was to assess the combined effect of several single studies of maternal obesity on the risk of orofacial clefts using meta-analysis. We searched for these reports in the PubMed database, and selected 8 studies that met our criteria for eligibility. As a result of this analysis, and using maternal normal weight as a reference, we found that maternal obesity does increase the risk of orofacial clefts in their offspring (OR 1.18, 95% CI 1.11 to 1.26). When these clefts are considered separately, maternal obesity is associated with cleft lip with or without cleft palate (OR 1.13, 95% CI 1.04 to 1.23), and with cleft palate alone (OR 1.22, 95% CI 1.09 to 1.35). Our results support the relation between maternal obesity and orofacial clefts, and confirm two previous meta-analyses that considered fewer studies. However, the molecular mechanisms underlying this statistical evidence have not been fully elucidated.

    The study gives a survey of the factors most frequently mentioned in the literature as factors likely to adversely affect a pregnancy. One essential aspect is the discussion of those factors that can be counted among the causes of malformations, as among others, prenatal radiation exposure. The study prepared within the framework of the research project `Radiobiological environmental monitoring in Bavaria` is intended to serve as a basis for a retrospective and prospective evaluation of infant mortality, perinatal conditions and occurrence of malformations in Bavaria, with the principal idea of drawing up an environment - related health survey. The study therefore, in addition to ionizing radiation also takes into account other detectable risks within the ecologic context, as e.g. industrial installations, refuse incineration plants or waste dumps, or urbanity.

    Complications of childbirth and pregnancy are leading causes of death among women of reproductive age. Developing countries account for 99% of maternal deaths. The aim of this study was to explore levels, causes and risk factors associated with maternal mortality in rural Tanzania. Longitudinal data (2002-2006) from Rufiji HDSS was used where a total of 26 427 women aged 15-49 years were included in the study; 64 died and there were 15 548 live births. Cox proportional hazards regression was used to assess the risk factors associated with maternal deaths. MMR was 412 per 100 000 live births. The main causes of death were haemorrhage (28%), eclampsia (19%) and puerperal sepsis (8%). An increased risk of 154% for maternal death was found for women aged 30-39 versus 15-19 years (HR=2.54, 95% CI=1.001-6.445). Married women had a protective effect of 62% over unmarried ones (HR=0.38, 95% CI=0.176-0.839).

    Both maternal and fetal genetic factors influence variations in response to prenatal ethanol exposure. To assess the effect of maternal genotype on the incidence of ethanol teratogenesis, a reciprocal cross study was conducted in an animal mode using the relatively susceptible C57BL/6J (B6) and the relatively resistant DBA/2J (D2) inbred mice. This mating pattern produced four embryonic genotypes: true-bred B6B6 and D2D2 litters and hybrid B6D2 and D2B6 litters. To examine the role of maternal egg cytoplasm as the source of variation that could account for a maternal effect, B6D2 and D2B6 F1 females were mated back to B6 males, which produced two additional embryonic genotypes: B6D2.B6 and D2B6.B6. Dams were intubated with either 5.8 g/kg of ethanol or an isocaloric amount of maltose-dextrin on day 9 of pregnancy. On day 18 of pregnancy, dams were sacrificed, fetuses were removed, weighed, sexed, and examined for gross morphological malformations. Every other fetus within a litter was prepared for either skeletal or soft tissue analysis. Results showed a higher rate of teratogenesis in the B6D2 group compared to the genetically similar D2B6 group, which indicates an influence of maternal genotype on susceptibility to ethanol teratogenesis. The percentage of affected male and female fetuses did not differ, which suggests that sex-linked factors are not responsible for the maternal effect. The backcross B6D2.B6 and D2B6.B6 litters did not differ significantly for any measure of teratogenesis, suggesting that differences in maternally transmitted cytoplasmic material are not the cause of the maternal effect. Factors that could account for the maternal effect are differences in the maternal uterine environment and genomic imprinting. Separating maternal from fetal-mediated mechanisms responsible for susceptibility to ethanol teratogenesis is needed for identifying mothers and infants at risk.

Methods: This was a cross-sectional study that evaluated data from the latest National Survey of Children and Women's Demographics and Health, carried out in Brazil in 2006-2007. Maternal employment and maternal level of schooling were the main exposures. The following nutritional outcomes in children were considered: height/age 2SD for overweight. Generalized estimating equations (GEE were utilized as the regression method. Results: After adjustments, it was observed that children whose mothers had low level of schooling had a higher chance of having short stature (OR = 3.97, 95% CI, 1.23-12.80 and children whose mothers worked outside the home were more likely to have excess weight (OR = 1.57, 95% CI, 1.02-2.42. Maternal employment was not associated with short stature in children (OR = 1.09, 95% CI, 0.67-1.77. Conclusion: Maternal level of schooling was associated with short stature in children and maternal employment with overweight, indicating the need to take into account the socioeconomic factors when proposing programs and strategies aimed at health and nutrition improvement of children, considering inter-sectoral interventions.

    The prevalence of overweight and obesity among women of reproductive age is increasing. We aimed to determine risk factors and maternal, fetal and childhood consequences of maternal obesity and excessive gestational weight gain. The study was embedded in a population-based prospective cohort study among 6959 mothers and their children. The study was based in Rotterdam, The Netherlands (2001-2005). Maternal lower educational level, lower household income, multiparity, and FTO risk allel were associated with an increased risk of maternal obesity, whereas maternal European ethnicity, nulliparity, higher total energy intake, and smoking during pregnancy were associated with an increased risk of excessive gestational weight gain (all p-values obesity was associated with increased risks of gestational hypertension (OR 6.31 (95% CI 4.30, 9.26)), preeclampsia (OR (3.61, (95% CI 2.04, 6.39)), gestational diabetes (OR 6.28 (95%CI 3.01, 13.06)), caesarean delivery (OR 1.91 (95% CI 1.46, 2.50)), delivering large size for gestational age infants (OR 2.97 (95% CI 2.16, 4.08)), and childhood obesity (OR 5.02 (95% CI:2.97, 8.45)). Weaker associations of excessive gestational weight gain with maternal, fetal and childhood outcomes were observed, with the strongest effects for first trimester weight gain. Our study shows that maternal obesity and excessive weight gain during pregnancy are associated with socio-demographic, lifestyle, and genetic factors and with increased risks of adverse maternal, fetal and childhood outcomes. As compared to prepregnancy overweight and obesity, excessive gestational weight gain has a limited influence on adverse pregnancy outcomes. Copyright © 2013 The Obesity Society.

MÉTODOS: estudo tipo caso-controle composto por 188 recém-nascidos, sendo que 47 compuseram o grupo casos (pH de artéria umbilical OBJECTIVES: to assess maternal risk factors associated with fetal acidosis. METHODS: a case-control type study was conducted of 188 neonates, of whom 47 comprised the case group (umbilical arterial pH <7.0 and 141 the control (umbilical arterial pH E7.1 <7.3. The study included only single-gestation neonates without congenital malformations. Both maternal and fetal variables were taken into consideration. Statistical analysis involved the calculation of the raw and adjusted Odds Ratio, Student's t-test, the chi-squared test and multivariate analysis using Enter-method non-conditional logistic regression. The level of statistical significance was set at p<0.05. RESULTS: in the case group higher percentages of caesarian sections and pre-term births were observed, involving almost five times as much intensive care and twenty-five times more likelihood of Apgar in the 5th minute <7. No association was observed between the groups and fetal presentation, mother's age, history of miscarriage, years of schooling of mother or attendance at prenatal sessions. After multivariate analysis, the only risk factors that remained significant were complications relating to the placenta or the umbilical cord. Deliveries involving complications relating to the placenta or the umbilical cord were three times more likely to involve fetal acidemia. CONCLUSIONS: acidemia among neonates was associated with a higher percentage of caesarians, premature births, a need for intensive care and treatment and an Apgar index of <7 in the 5th minute. After multivariate analysis, complications relating to premature displacement of the placenta and the umbilical cord were the only remaining risk factors associated with fetal acidemia.

    Maternity blues and postpartum depression are common mental health problems during the early postpartum period. However, few studies have examined the factors associated with maternity blues and postpartum depression in healthy mothers with spontaneous births of healthy full-term infants. This study aimed to determine the demographic and obstetric factors, various feelings during pregnancy, and psychological factors by using the Maternity Blues Scale (MBS) and Edinburgh Postnatal Depression scale (EPDS) among healthy Japanese mothers. We distributed the MBS and EPDS self-administered questionnaires to 100 Japanese mothers during their 4-5 day hospitalization and at a health check-up 1-month after delivery, respectively. Multiple regression analyses were performed including the above-mentioned variables as independent variables and the maximum MBS or EPDS scores as dependent variables. The answers "Having a friend I can talk to about maternity life or child rearing" [beta (95% confidence interval) = -1.53 (-2.68 - -0.378)] and "Satogaeri bunben", a Japanese traditional support system wherein a postnatal woman lives with her husband/parents [-2.82 (-4.73 - -0.898)] were significantly associated with MBS scores. The answer "Having a friend I can talk to about maternity life or child rearing" [-2.83 (-4.76 - -0.903)] was also significantly associated with EPDS scores, although the association between the partner's age and these scores was marginally significant [-0.106 (-0.008 - 0.221)]. This study shows that it is important to provide support for healthy women without delivery complications, both at home and in the community.

    Full Text Available Abstract Background Fibroblast growth factors (FGFs and their receptors (FGFRs are necessary for the proper development of gonadotropin-releasing hormone (GnRH neurons, which are key activators of the hypothalamo-pituitary-gonadal axis. Transgenic mice that have the targeted expression of a dominant negative FGFR (dnFGFR in GnRH neurons (dnFGFR mice have a 30% decrease of GnRH neurons. Additionally, only 30–40% of the pups born to the transgenic dams survive to weaning age. These data raised the possibility that FGFR defects in GnRH neurons could adversely affect maternal behavior via novel mechanisms. Methods We first determined if defective maternal behavior in dnFGFR mothers may contribute to poor pup survival by measuring pup retrieval and a battery of maternal behaviors in primiparous control (n = 10–12 and dnFGFR (n = 13–14 mothers. Other endocrine correlates of maternal behaviors, including plasma estradiol levels and hypothalamic pro-oxyphysin and GnRH transcript levels were also determined using enzyme-linked immunoassay and quantitative reverse transcription polymerase chain reaction, respectively. Results Maternal behaviors (% time crouching with pups, time off pups but not feeding, time feeding, and total number of nesting bouts were not significantly different in dnFGFR mice. However, dnFGFR dams were more likely to leave their pups scattered and took significantly longer to retrieve each pup compared to control dams. Further, dnFGFR mothers had significantly lower GnRH transcripts and circulating E2, but normal pro-oxyphysin transcript levels. Conclusions Overall, this study suggests a complex scenario in which a GnRH system compromised by reduced FGF signaling leads to not only suboptimal reproductive physiology, but also suboptimal maternal behavior.

    Full Text Available Aim: The aim of this study is to assess the maternal risk factors and its relationship with early childhood caries (ECC among preschoolchildren in Mangaluru city. Methods: Children aged 3–5 years attending preschool (Anganwadi and their mothers were included in the study. A total of 120 child–mother pairs participated in the study. The maternal risk factors were assessed by a pretested questionnaire. After obtaining the consent, the mother and their children were clinically examined for dental caries using the WHO criteria (1997. Results were analyzed using SPSS 18.0. Results: Significant difference was found in mother's caries activity, high level of Streptococcus mutans, brushing frequency, diet of the mother, and their child's caries experience. Conclusion: A relationship between maternal risk factors and ECC is a result of a multifactorial and a comprehensive model that includes psychological and behavioral aspects. Caries prevention strategy should be that every child should receive oral care before age of one so that needful children can be instituted with preventive measures and their parents can be targeted for educational programs.

  15. Risk Factors for Maternal Mortality in Rural Tigray, Northern Ethiopia: A Case-Control Study.

    Full Text Available Maternal mortality continues to have devastating impacts in many societies, where it constitutes a leading cause of death, and thus remains a core issue in international development. Nevertheless, individual determinants of maternal mortality are often unclear and subject to local variation. This study aims to characterise individual risk factors for maternal mortality in Tigray, Ethiopia.A community-based case-control study was conducted, with 62 cases and 248 controls from six randomly-selected rural districts. All maternal deaths between May 2012 and September 2013 were recruited as cases and a random sample of mothers who delivered in the same communities within the same time period were taken as controls. Multiple logistic regression was used to identify independent determinants of maternal mortality.Four independent individual risk factors, significantly associated with maternal death, emerged. Women who were not members of the voluntary Women's Development Army were more likely to experience maternal death (OR 2.07, 95% CI 1.04-4.11, as were women whose husbands or partners had below-median scores for involvement during pregnancy (OR 2.19, 95% CI 1.14-4.18. Women with a pre-existing history of other illness were also at increased risk (OR 5.58, 95% CI 2.17-14.30, as were those who had never used contraceptives (OR 2.58, 95% CI 1.37-4.85. Previous pregnancy complications, a below-median number of antenatal care visits and a woman's lack of involvement in health care decision making were significant bivariable risks that were not significant in the multivariable model.The findings suggest that interventions aimed at reducing maternal mortality need to focus on encouraging membership of the Women's Development Army, enhancing husbands' involvement in maternal health services, improving linkages between maternity care and other disease-specific programmes and ensuring that women with previous illnesses or non-users of contraceptive services

    Macrosomia is defined as birth-weight over 4,000 g irrespective of gestational age and affects 3-15% of all pregnancies. Aim The present study aimed to determine the relationship between mother's characteristics and macrosomic births and also compare macrosomic and normal newborns regarding the maternal and offspring complications of diabetes during pregnancy. In this case control study, among the 420 consecutive births occurring in public and private hospitals of Shiraz, Iran from October 2006 to March 2007, the data of 32 macrosomic and 128 normal newborns were analyzed using t-test and chi square in bivariate and logistic regression in multivariate model. The mean (SD) of neonate weight, height, and head size was 3323.4 (709), 48.95 (3.2), and 34.9 (1.8), respectively. Regression analysis showed that gestational diabetes (Odds Ratio (OR): 11.9, Confidence Interval (CI): 4.6-30.3), preeclampsia in the pregnancy period due to diabetes (OR: 3.81, CI: 1.1-13.2), and macrosomic birth history (OR: 3.3, CI: 1.04-10.4) were the main predictors of macrosomia. Moreover, macrosomia increased neonate hypoglycemia (OR: 4.7, CI: 1.4-15.8) and section delivery (OR: 4.1, CI: 1.27-13.1). Gestational diabetes, preeclampsia due to diabetes, and history of macrosomic birth were the main predictors of macrosomia. Moreover, macrosomia increased some delivery complications for both mothers and newborns.

    Objective:To investigate the socio-cultural factors that contribute to Maternal Mortality in Edo South Senatorial District. Methods:The population of the study was made up of 2 157 females of reproductive age and multi-stage random sampling technique was used. The instrument for data collection was a self developed structured and validated questionnaire with a reliability of 0.82. Focus group discussion (FGD) and in-depth interview guide were employed to complement the instrument. Inferential statistics of multiple regressions were also employed to test the hypotheses at 0.05 level of significance. Results:The results showed that the socio-cultural variables when taken together contributed positively to maternal mortality [R2=0.32;CV=16.5;df=7). The finding further revealed that six, out of seven of the independent variables in the study significantly contributed to maternal mortality in Edo South Senatorial District. The implications of these findings in maternal and child health care were highlighted. Conclusions:The study had shown that in addition to medical causes of maternal mortality, there are socio-cultural factors that contribute to women dying during pregnancy, labour and pueperium.

    in Ethiopia, 20,000 women die each year from complications related to pregnancy and childbirth with much more maternal morbidity occurring for each maternal death. Good knowledge of women related with direct causes of maternal mortality is important in reducing maternal morbidity and mortality. Therefore, the aim of this study was to assess knowledge of direct obstetric causes of maternal mortality and associated factors among reproductive age of women in Aneded woreda, Northwest Ethiopia. A community-based cross-sectional study was conducted using multi-stage sampling followed by simple random sampling technique. The study was conducted in Aneded woreda, Northwest Ethiopia. A total of 844 reproductive age women were included in the study. Pre-tested semi-structured questionnaire was used to collect the data. Data was collected through face-to-face interviews by 12 data collectors. Data was cleaned, coded and entered into Epi-data, then exported and analyzed using SPSS software. Bivariate and multivariable logistic regression analysis were computed to identify factors related to knowledge of obstetric causes of maternal mortality. The crude and adjusted odds ratios together with their corresponding 95% confidence intervals (CI) were computed. A P-value less than 0.05 was used to declare statistical significance. This study found that almost half (49.6%) of respondents have good knowledge level towards obstetric causes of maternal mortality. Significant variables associated with knowledge towards obstetric causes of maternal mortality were; being government employee (AOR=3.6, 95% CI=1.4-8.9), respondents who had additional monthly income from family members (AOR=1.54, 95% CI=1.04-2.27), respondents who attended primary school and above (AOR=1.6, 95% CI=1.13-2.25), distance of health facility in which the time it took less than 20 minutes (AOR=2.25, 95% CI(1.24-4.09), 20-39minutes (AOR=3.06, 95% CI=1.66-5.64), 40-60 minutes (AOR=2.38, 95% CI=1.52-5.26), and previous

    The role of insulin-like growth factors (IGFs) in fetal development has been the subject of much speculation. We undertook studies of maternal and fetal IGF I and II in the guinea pig because the long gestation period and greater size of the fetuses permitted blood sampling over a longer period of gestation and maturation than is possible in the rat. Acid gel filtrates of fetal and maternal serum were prepared, and the IGF I was measured by RIA; IGF II was measured by rat placental membrane radioreceptor assay. Fetal IGF I levels were lower than maternal levels from the 33rd day of estimated gestation to term. Fetal IGF II levels from the 33rd day to the 49th day of gestation were not significantly different from those of maternal serum [1597 +/- 377 (SE) ng/ml vs. 1295 +/- 224] ng/ml. Very high levels of IGF II, in excess of 5000 ng/ml, were observed in fetuses at 50, 55, and 60 days of gestation. Thereafter, fetal IGF II levels fell markedly before term. Fetal and maternal IGFs after 49, 50, 60, and 65 days of pregnancy were compared by isoelectric focusing. The guinea pig normally has two major basic peaks of IGF I, which were present both in maternal and fetal serum. Most maternal and fetal guinea pig sera contained only a single, slightly acidic peak of IGF II. No evidence of a unique fetal IGF was detected by our methods. The very high levels of IGF II reached in fetal guinea pig sera suggest that it may have a role in fetal development.

    To assess: (1) the prenatal distress level in Turkish pregnant women and (2) to examine the association between prenatal maternal distress and personal and pregnancy-specific factors. Pregnant women experience stress originating from a variety of pregnancy-specific issues, including physical symptoms and changes, changes in body image, physiological, social and emotional changes, parenting concerns, changes in relationships with significant others, medical problems, anxiety about labour and delivery, concerns about birth and the baby's health. A descriptive cross-sectional study. This study was conducted at a gynaecology clinic of a private hospital in Istanbul, Turkey within a 12-month period. The study sample comprised 522 pregnant women continuing their regular visits for prenatal care. Pregnancy Description Form and Turkish Version of Revised Version of Prenatal Distress Questionnaire [(NUPDQ)-17 Item Version] were used for data collection. Study sample was moderately distressed. Turkish pregnant women were mostly distressed and concerned about premature delivery, having an unhealthy baby, labour and delivery, feeling tired and having low energy during pregnancy. Prenatal distress in Turkish pregnant women was associated with personal and pregnancy-related characteristics. This study found that pregnant women need to be supported emotionally, physically and socially. A better understanding of prenatal maternal distress could assist in informing healthcare professionals about the provision of physically, emotionally, socially and behaviourally appropriate support for achieving a healthy pregnancy. It is crucial for pregnant women to be regularly assessed and educated for dealing successfully with concerns and fears about prenatal period, birth and postnatal period and about difficulties that women may encounter during their pregnancy. © 2013 Blackwell Publishing Ltd.

    Full Text Available The Rapid Reduction of Maternal and Neonatal Mortality is a health system responsive to the needs of all mothers and children. While various efforts are being undertaken to improve the implementation of maternal health program among pregnant women and immunization for children, there is a slow take up of these services. Factors influencing the slow demand for MCC services among mothers and children are not fully known. Factors hindering the delivery of these services need to be probed. This study used the descriptive method of research to describe the responses of mothers about the factors influencing slow availment of Maternal and Child Care Services. There were 396 mothers in Region 1 who willingly participated during focused group discussion. The highly availed services by mothers were: 1. pre-natal service, 2. Immunization, and 3. Family planning. Health services availed by the respondents’ children were: 1. Management of childhood illness, 2. Immunization, and 3. Infant and young feeding. The mothers’ deep concern for her baby’s safety and health; free but limited medical services from competent health workers; inadequate supplies and equipment; distance to the nearest health facility, family income, mothers’ education and dialect for communication influenced delivery of the program. To increase the utilization of MCC services, government hospitals should give free complete MCC services to the poor, the mothers should be informed about the benefits of complete maternal services for her baby and herself, enhance dissemination campaign through leaflets, flyers, pamphlets, and seminars.

    Fetal macrosomia is usually defined when the estimated fetal weight is greater than or equal to 4000 grams. The aim of this study was to determine the incidence of macrosomia, to identify its etiological factors and to evaluate maternal and perinatal prognosis. This is a case-control study conducted in maternity units of 10 general referral hospitals in the city of Lubumbashi in Democratic Republic of Congo between 1 December 2013 and 31 March 2014. The post-partum women were divided into two groups according to their fetal birth weight: group I (≥4000 grams or more) and groups II (from 2500 to 3500 grams). Maternal characteristics, obstetrical environment as well as maternal and perinatal prognosis were studied and compared in the two groups. Data were analyzed using Epi Info 7.1 software. Differences were considered significant if p macrosomia was 5,7%. Compared to mothers from the control group, we found that mothers of macrosomic infants were older, multiparous, multigravidae, obese, diabetic and had previously delivered a macrosomic fetus. The rates of cesarean delivery and pathological delivery were significantly higher in mothers of macrosomic infants than in those of the control group. Male sex was significantly more prevalent among macrosomic infants than among the control group. Shoulder dystocia was recorded only in the macrosomic group. The prevalence of delivery of a macrosomic infant in Lubumbashi is 5,7%. Macrosomia is often the cause of maternal and perinatal complications. Reduction of maternal and perinatal complications passes through a better understanding of risk factors and an early detection.

    Child malnutrition, including wasting, underweight and stunting, is associated with infections, poor nutrient intake, and environmental and socio-demographic factors. Preschool-age children are especially vulnerable due to their high growth requirements. To target interventions for preschool-age children in a community of extreme poverty in Peru, we conducted a household survey between October 2005 and January 2006 to determine the prevalence of malnutrition and its risk factors. Of 252 children Child Growth Standards. Risk factors for wasting were: (1) moderate-high intensity Trichuris infection (OR 2.50; 95 % CI 1.06, 5.93); (2) hookworm infection (OR 6.67; 95 % CI 1.08, 41.05); (3) age (OR6-month 1.27; 95 % CI 1.11, 1.46); (4) maternal education (secondary incomplete) (OR 5.77; 95 % CI 2.38, 13.99); and (5) decreasing maternal BMI (OR1 kg/m2 1.12; 95 % CI 1.02, 1.23). Risk factors for underweight were: (1) moderate-high intensity Trichuris infection (OR 4.74; 95 % CI 1.99, 11.32); (2) age (OR6-month 1.22; 95 % CI 1.07, 1.38); (3) maternal education (secondary incomplete) (OR 2.92; 95 % CI 1.40, 6.12); and (4) decreasing maternal BMI (OR1 kg/m2 1.11; 95 % CI 1.02, 1.21). Risk factors for stunting were: (1) age (OR6-month 1.14; 95 % CI 1.02, 1.27) and (2) decreasing maternal height (OR1 cm 1.12; 95 % CI 1.06, 1.20). Overall, risk factors for malnutrition included both child and maternal determinants. Based on these data, locally appropriate and cost-effective dietary, de-worming and educational programmes should be targeted to mothers and preschool-age children.

    Sport participation is especially important for patients with asthma in that it decreases psychosocial and physiological problems associated with inactivity. However, adolescents with asthma seem to participate less in sports compared to their non-asthmatic peers. The current study tested the direct associations between maternal sport-specific factors and sport club participation of early adolescents with asthma and the indirect effect through adolescent's sport-specific cognitions. During home visits, 261 adolescents (aged 10-15) completed questionnaires about self-efficacy, beliefs regarding sport participation, and their actual sport club participation. Their mothers reported their sport-specific support, beliefs about offspring's and own sport participation, their own levels of physical activity, and their self-efficacy to stimulate offspring to participate in sports. Path analyses were used to examine the direct and indirect associations of maternal sport-specific factors with adolescents sport club participation via adolescent sport-specific cognitions. Analyses showed that maternal sport-specific support (β = 0.20, P = 0.007) and self-efficacy to stimulate offspring to participate in sports (β = 0.20, P = 0.027) related positively to adolescents' sport club participation. Adolescents' self-efficacy (indirect effect = 0.09, SE = 3.01, P sport and adolescents' participation in sport clubs.

    In mammalian reproduction, embryo implantation into the uterus is spatiotemporally regulated by a complex process triggered by a number of factors. Although previous studies have suggested that uterine receptivity is mediated by blastocyst-derived factors, specific functions of embryos remain to be defined during preimplantation. Therefore, the present study was conducted to identify the maternal genes regulated by embryo-secreted factors in the rat uterus. RNA-sequencing (RNA-seq) data revealed that 10 genes are up-regulated in the delayed implantation uterus compared with the pseudopregnancy uterus. The RNA-seq results were further verified by real-time quantitative polymerase chain reaction. Sulf1 expression is significantly (P media revealed that Lamc3 and Sulf1 are up-regulated compared with the other genes studied. Thus, embryo-derived factors regulate maternal gene expression, with Lamc3 and Sulf1 possibly being suitable markers for a response study of embryo-secreted factors to improve our understanding of embryo-maternal communication.

    We report on a 21-year-old pregnant patient with IgA nephropathy who was initiated on intensive hemodialysis (8 hours of hemodialysis 3 times a week) at a gestational age of 26 weeks on the basis of worsening kidney function resulting in rapidly progressive fatigue and difficulties in metabolic control. Throughout the pregnancy, and while on intensive hemodialysis, 24-hour ambulatory blood pressure control was within the target, and results of weekly 24-hour measurement of central hemodynamics and pulse wave velocity, and of serial levels of circulating (anti-)angiogenic factors were comparable to normal pregnancies. Estimated fetal growth evolved along the 50th percentile, and no polyhydramnios was detected. After induction for a sudden, unexplained increase in blood pressure, she delivered a healthy boy of 2480 g at a gestational age of 36 weeks. This case adds to the expanding literature that supports the use of intensive hemodialysis in pregnant patients with end-stage renal disease and illustrates, for the first time, the potential use of serial (anti-) angiogenic factors and 24-hour measurements of blood pressure and hemodynamic indices in order to facilitate monitoring of these complicated patients.

    Full Text Available Abstract Background Maternal death reviews have been utilized in several countries as a means of identifying social and health care quality issues affecting maternal survival. From 2005 to 2009, a standardized community-based maternal death inquiry and response initiative was implemented in eight Indian states with the aim of addressing critical maternal health policy objectives. However, state-specific contextual factors strongly influenced the effort's success. This paper examines the impact and implications of the contextual factors. Methods We identified community, public health systems and governance related contextual factors thought to affect the implementation, utilization and up-scaling of the death inquiry process. Then, according to selected indicators, we documented the contextual factors' presence and their impact on the process' success in helping meet critical maternal health policy objectives in four districts of Rajasthan, Madhya Pradesh and West Bengal. Based on this assessment, we propose an optimal model for conducting community-based maternal death inquiries in India and similar settings. Results The death inquiry process led to increases in maternal death notification and investigation whether civil society or government took charge of these tasks, stimulated sharing of the findings in multiple settings and contributed to the development of numerous evidence-based local, district and statewide maternal health interventions. NGO inputs were essential where communities, public health systems and governance were weak and boosted effectiveness in stronger settings. Public health systems participation was enabled by responsive and accountable governance. Communities participated most successfully through India's established local governance Panchayat Raj Institutions. In one instance this led to the development of a multi-faceted intervention well-integrated at multiple levels. Conclusions The impact of several contextual

    Recent research suggests the maternal environment may be especially important for the risk of developing autism spectrum disorders (ASD). In particular maternal infections, micronutrient deficiencies, obesity, and toxicant exposures are likely to interact with genetic risk factors to disrupt fetal brain development.

    Contrary  to  our  expectations,  no  differences  between  groups  of  the  participants from single children and firstborns and the rest of the sample were found. Conclusion. Parents’ demands, criticism and high expectations are related to their children  being  excessively  critical  to  themselves  and  becoming  perfectionists.  The research provides clues for further explorations of perfectionism: on possible mediating factors  of  perfectionism  development  in  single  children  and  firstborns;  cultural differences  in  perfectionism  development  as  for  more  influential  impact  on  it  from mothers or fathers; and possible child’s characteristics which contribute to development of perfectionism when parents practice the same rearing style.

    To evaluate the interaction and contribution of maternal and fetal risk factors associated with neonatal brachial plexus injury (BPI). In a case-control study, matched maternal and neonatal discharge records were accessed from US State Inpatient Databases for New Jersey (2010-2012), Michigan (2010-2011), and Hawaii (2010-2011). Univariate and multivariate logistic regressions were used to evaluate associations between risk factors and BPI. Area under the receiver operating characteristic curve was used to build predictive models, including two stratified models evaluating deliveries among obese and diabetic cohorts. Among 376 325 deliveries, BPI was diagnosed in 274 (0.1%). Significant BPI risk factors included maternal obesity (odds ratio [OR] 2.7, 95% confidence interval [CI] 1.7-4.4), maternal diabetes (OR 4.6, 95% CI 3.0-7.0), use of forceps (OR 4.6, 95% CI 2.3-9.0), and vacuum assistance (OR 2.3, 95% CI 1.7-3.3). After adjusting for shoulder dystocia and other predictive factors, cesarean reduced the risk of BPI by 88% (OR 0.1, 95% CI 0.07-0.2). When stratified by obesity and diabetes, the ORs for BPI increased significantly for macrosomia, forceps, and vacuum assistance. The analysis confirms and quantifies more precisely the impact of risk factors for neonatal BPI, and provides a reliable basis for evidence-based clinical decision-making models. © 2016 International Federation of Gynecology and Obstetrics.

  20. The maternally expressed WRKY transcription factor TTG2 controls lethality in interploidy crosses of Arabidopsis.

    Full Text Available The molecular mechanisms underlying lethality of F1 hybrids between diverged parents are one target of speciation research. Crosses between diploid and tetraploid individuals of the same genotype can result in F1 lethality, and this dosage-sensitive incompatibility plays a role in polyploid speciation. We have identified variation in F1 lethality in interploidy crosses of Arabidopsis thaliana and determined the genetic architecture of the maternally expressed variation via QTL mapping. A single large-effect QTL, DR. STRANGELOVE 1 (DSL1, was identified as well as two QTL with epistatic relationships to DSL1. DSL1 affects the rate of postzygotic lethality via expression in the maternal sporophyte. Fine mapping placed DSL1 in an interval encoding the maternal effect transcription factor TTG2. Maternal parents carrying loss-of-function mutations in TTG2 suppressed the F1 lethality caused by paternal excess interploidy crosses. The frequency of cellularization in the endosperm was similarly affected by both natural variation and ttg2 loss-of-function mutants. The simple genetic basis of the natural variation and effects of single-gene mutations suggests that F1 lethality in polyploids could evolve rapidly. Furthermore, the role of the sporophytically active TTG2 gene in interploidy crosses indicates that the developmental programming of the mother regulates the viability of interploidy hybrid offspring.

    To determine risk factors for miscarriage. A case control study was carried out at the gynaecological wards and antenatal clinics of the De Soysa Maternity Hospital in Sri Lanka. A case was defined as that of mothers with a confirmed diagnosis of partial or full expulsion of the fetus during the first 28 weeks of gestation. Controls comprised ante-natal clinic attendees whose period of gestation was sedentary lifestyle, exposure to cooking smoke and physical trauma during pregnancy were risk factors for miscarriage. Most of the risk factors are therefore modifiable.

    Problem Visfatin/pre-B-cell enhancing factor (PBEF) has been implicated in the regulation of the innate immune system, as well as in glucose metabolism. Specifically, visfatin plays a requisite role in delayed neutrophil apoptosis in patients with sepsis. The aim of this study was to determine whether pyelonephritis during pregnancy is associated with changes in maternal plasma visfatin concentration in normal weight and overweight/obese patients. Methods of Study This cross-sectional study included the following groups: 1) normal pregnant women (n=200); and 2) pregnant women with pyelonephritis (n=40). Maternal plasma visfatin concentrations were determined by ELISA. Non-parametric statistics were used for analyses. Results 1) The median maternal plasma visfatin concentration was significantly higher in patients with pyelonephritis than in those with a normal pregnancy; 2) among overweight/obese pregnant women, those with pyelonephritis had a significantly higher median plasma visfatin concentration than women with a normal pregnancy; and 3) pyelonephritis was independently associated with higher maternal plasma visfatin concentrations after adjustment for maternal age, pre-gestational BMI, smoking status, gestational age at sampling, and birthweight. Conclusions Acute pyelonephritis during pregnancy is associated with a high circulating maternal visfatin concentration. These findings suggest that visfatin/PBEF may play a role in the regulation of the complex and dynamic crosstalk between inflammation and metabolism during pregnancy. PMID:20085562

    Full Text Available Abstract Background Previous studies of maternal risk factors for abnormal placental growth have focused on placental weight and placental ratio as measures of placental growth. We sought to identify maternal risk factors for placental weight and two neglected dimensions of placental growth: placental thickness and chorionic plate area. Methods We conducted an analysis of 24,135 mother-placenta pairs enrolled in the National Collaborative Perinatal Project, a prospective cohort study of pregnancy and child health. We defined growth restriction as th percentile and hypertrophy as > 90th percentile for three placental growth dimensions: placental weight, placental thickness and chorionic plate area. We constructed parallel multinomial logistic regression analyses to identify (a predictors of restricted growth (vs. normal and (b predictors of hypertrophic growth (vs. normal. Results Black race was associated with an increased likelihood of growth restriction for placental weight, thickness and chorionic plate area, but was associated with a reduced likelihood of hypertrophy for these three placental growth dimensions. We observed an increased likelihood of growth restriction for placental weight and chorionic plate area among mothers with hypertensive disease at 24 weeks or beyond. Anemia was associated with a reduced likelihood of growth restriction for placental weight and chorionic plate area. Pre-pregnancy BMI and pregnancy weight gain were associated with a reduced likelihood of growth restriction and an increased likelihood of hypertrophy for all three dimensions of placental growth. Conclusion Maternal risk factors are either associated with placental growth restriction or placental hypertrophy not both. Our findings suggest that the placenta may have compensatory responses to certain maternal risk factors suggesting different underlying biological mechanisms.

    Factors associated with maternal satisfaction of anesthetic management during labour and delivery are poorly known. The purpose of this study was to assess these factors. We performed a retrospective cohort study on parturients admitted between January 2004 and December 2008. Data on patients' demographics, comorbidities, procedures performed and various aspects of their anesthetic experience were retrieved from the anesthetic records. Maternal satisfaction was measured using a numerical scale from 0 to 10 (0 = not satisfied at all, 10 = very satisfied). A cutoff of ≤ 6 was taken as poor satisfaction. We performed a multivariate analysis to identify the different predictors of maternal satisfaction and more specifically those related to pain, overall experience with the technique, delays, and presence of anesthetic, obstetrical and neonatal complications. There were 15,386 parturients admitted during the study period. Of these, 10,034 had complete information in the chart and 761 (7.6%) parturients were dissatisfied with their anesthetic care. Factors decreasing patient satisfaction were high risk pregnancy [odds ratio (OR) 95% confidence interval (CI) 0.59 (0.34-1.02)] and difficult delivery [OR (95% CI) 0.62 (0.52-0.74)]. Pain, a negative experience of the procedure, delays, poor coordination in management, and the presence of complications decreased patient satisfaction [OR (95% CI) 0.07 to 0.71]; P technical and human point of view. However, other factors such as a good coordination in patient management and the absence of complications also influence maternal satisfaction.

    Background: There have been speculations about the effects of hormonal changes and socio-demographic factors on periodontal health during pregnancy. Objective: According to the lack of sufficient epidemiologic information about the periodontal status of pregnant women in Yazd, this study was accomplished to determine the changes of Community Periodontal Index for Treatment Needs (CPITN) during pregnancy and evaluating the possible relationship between this index and demographic characteristics of the mothers. Materials and Methods: This was a longitudinal descriptive study. The samples included 115 pregnant women who were referred to health centers of Yazd, Iran. The mothers’ data were obtained from a questionnaire consisted of 3 parts: consent paper, demographic data and CPITN records. Examination was performed with dental unit light, flat dental mirror and WHO’s scaled probe. Results: In the beginning of the study, 60.1% of checked sextants had healthy gingival status. 25.9% had code1 and 14% had code 2. Code 3 and 4 were not seen in any sextants. There was a significant relationship between lower CPITN and higher maternal education, occupation and more frequencies of tooth-brushing but there was not a relationship between CPITN and mother’s age and number of pregnancies. CPITN had a significant relationship with increasing of the gestational age. Conclusion: There might be a relationship between increasing the month of pregnancy and more periodontal treatment needs. CPITN Increasing during pregnancy shows the importance of periodontal cares during this period. PMID:26000000

    Access to health care is still limited for many women in sub-Saharan Africa (SSA), while it remains an important determinant of maternal mortality and morbidity. Information and communication technologies (ICTs), such as mhealth and telehealth, can help to facilitate this access by acting on the various obstacles encountered by women, be they socio-cultural, economic, geographical or organizational. However, various factors contribute to the success of mhealth and telehealth implementation and use, and must be considered for these technologies to go beyond the pilot project stage. The objective of this systematic literature review is to synthesize the empirical knowledge on the success factors of the implementation and use of telehealth and mhealth to facilitate access to maternal care in SSA. The methodology used is based on that of the Cochrane Collaboration, including a documentary search using standardized language in six databases, selection of studies corresponding to the inclusion criteria, data extraction, evaluation of study quality, and synthesis of the results. A total of 93 articles were identified, which allowed the inclusion of seven studies, six of which were on mhealth. Based on the framework proposed by Broens et al., we synthesized success factors into five categories: (I) technology, such as technical support to maintain, troubleshoot and train users, good network coverage, existence of a source of energy and user friendliness; (II) user acceptance, which is facilitated by factors such as unrestricted use of the device, perceived usefulness to the worker, adequate literacy, or previous experience of use ; (III) short- and long-term funding; (IV) organizational factors, such as the existence of a well-organized health system and effective coordination of interventions; and (V) political or legislative aspects, in this case strong government support to deploy technology on a large scale.

    Full Text Available Purpose: evaluate 1 whether child’s externalizing problems increase or decrease within 12 months period; 2 the change of externalizing problems with respect to child gender and age, and 3 which maternal parenting stress factors and family sociodemographic characteristics can predict the increase and decrease of child’s externalizing problems. Design/methodology/approach: participants were evaluated 2 times (with the interval of 12 months with the Parenting Stress Index (Abidin, 1990 and Child Behavior Checklist 1.5−5 years (Achenbach, Rescorla, 2000 questionnaires. Findings: Child’s externalizing problems decreased within 12 months period. There were no effects of child’s age, gender and age*gender interaction on externalizing problems change within 12 months period. Higher initial level and more negative change within 12 months period of maternal parenting stress related to child characteristics, more stressful events in family life predicted the increase of child’s externalizing problems. Research limitations/implications: maternal parenting stress and child’s externalizing problems are related and may influence each other simultaneously. Child’s externalizing problems decrease within one year period in overall 2−5 years old children group. The change of child’s aggressive behavior and hyperactivity, distractibility should be evaluated individually, separately from each other. Practical implications: maternal parenting stress and child’s behavior problems are closely related to each other, it may be meaningful organize intervention for mothers in order to prevent child’s externalizing problems increase. Keywords: maternal parenting stress, externalizing problems, childhood, toddlerhood, longitudinal research. Research type: research paper.

    Full Text Available The aims of this study were to assess the levels of knowledge, attitudes and behaviors of women about the main maternal risk factors in pregnancy and to identify the factors linked to the main outcomes of interest.A cross-sectional survey was conducted in 513 pregnant women randomly selected from the gynecological ambulatory services of five hospitals located in Naples, Italy.Only 42% of women correctly knew all the main maternal risk factors in pregnancy (alcohol, smoking, passive smoking and obesity. Only 21.7% of women were very worried about causing harm to the fetus or child with their risk behaviors, and 22.3% of women reported smoking during pregnancy. Approximately one-third of women (28.9% reported regularly drinking alcohol before pregnancy and 74.8% of these women reported stopping drinking alcohol during pregnancy. However, only 27.3% of women who were drinking alcohol during pregnancy had the intention of stopping. Only 43.7% of women indicated that during ambulatory gynecological examinations they received information from physicians about the possible damage resulting from all the main risk factors in pregnancy (alcohol, smoking, passive smoking and obesity.The results indicate that pregnant women lack knowledge regarding the main maternal risk factors. Pregnant women claim to receive little information during gynecological examinations and, therefore, some continue to smoke and drink alcohol during pregnancy. Our results suggest an urgent need for the design of interventions to improve women's levels of knowledge and to promote appropriate behavior in relation to the major risk factors in pregnancy.

    Recent evidence shows that almost 92% of the DS children are born from young mothers, suggesting that other risk factors than advanced maternal age must be involved. In this context, some studies demonstrated a possible link between DS and maternal polymorphisms in genes involved in folate metabolism. These polymorphisms, as well as low intake of folate could generate genomic instability, DNA hypomethylation and abnormal segregation, leading to trisomy 21. We compared the frequency of CBS 844ins68, MTR 2756A>G, RFC-1 80G> A and TC 776C>G polymorphisms among 114 case mothers and 110 matched controls, in order to observe whether these variants act as risk factors for DS. The genotype distributions revealed that there were not significant differences between both samples. However, when we proceed the multiplicative interaction analyses between the four polymorphisms described above together with the previously studied MTHFR 677C>T, MTHFR 1298A>C and MTRR 66A>G polymorphisms, our results show that the combined genotype TC 776CC / MTHFR 677TT and TC 776CC / MTR 2756AG were significantly higher in the control sample. Nevertheless, there was no significant association after Bonferroni correction. Our results suggest that maternal folate-related polymorphisms studied here have no influence on trisomy 21 susceptibility in subjects of Brazilian population.

    Objectives: To determine characteristics of laboratory parameters of hematopoietic potential in umbilical cord blood and their association with maternal and neonatal factors. Methods: This prospective analysis was performed on 206 umbilical cord blood donations (50-200 ml) from King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia between January and September 2014. Samples were processed and analyzed for total nucleated cells (TNC’s), cluster designation (CD)45+, CD34+ counts, nucleated red blood cells (NRBCs) count, and viability testing. Results: Most of the study participants (63.6%) were on their first 3 deliveries and from women with age between 17 and 30 years (80.6%). The donated volume was 50.4-192.4 ml, TNCs ranged from 500.2×106 to 9430.3 ×106 cells, and CD34+ cells ranged from 1.25×106 to 12.82×106/unit. The volume was positively affected by bigger birth weight of the baby (pumbilical cord blood, several maternal and neonatal factors should be considered, as younger maternal age, neonatal birth weight >3300 grams, larger placental size, and first or second-born babies, were shown to be associated with higher TNCs, CD34+, CD45+, NRBCs, and viability.

    Globalization and women empowerment have led to stressful life among Indian women. This stress impairs women’s hormonal makeup and menstrual cycle, leading to infertility. National Family Health Survey-3 (NFHS-3) reports a decline in fertility status in India, indicating a rise in various infertility treatments involving hormonal interventions. No studies are available from India on the risk association link between maternal hormonal treatments and ASD. Hence, this study explores the association of maternal hormonal interventions with risk for ASD. Parents of 942 children (471 ASD and 471 controls) across 9 cities in India participated in the questionnaire-based study. The questionnaire was pilot tested and validated for its content and reliability as a psychometric instrument. Data collection was done at 70 centres through direct interaction with parents and with the help of trained staff. Statistical analysis of data was carried out using SAS 9.1.3. Out of the 471 ASD cases analysed, 58 mothers had undergone hormonal interventions (12.3%) while there were only 22 mothers among controls who underwent hormonal interventions (4.6%). According to logistic regression analysis maternal hormonal intervention (OR=2.24) was a significant risk factor for ASD.

    Full Text Available Background: Macrosomia is a term applied to newborns with a birth weight of 4000 gr or above. Perinatal mortality and morbidity is increased in fetal macrosomia. Clavicular fracture, injury to brachial plexus, and hypoglycemia are important side effects. Mother’s age, body mass index of mother, weight gain in pregnancy, mother’s height, diabetes, history of macrocosmic delivery, gestational age, parity, and fetal sex are factors causing macrosomia. The purpose of this cross-sectional study was to evaluate the frequency and risk factors of macrosomia in Asalian hospital of Khorramabad in the summer of 2010. Methods: The data collection instrument was a questionnaire containing 10 variables as the risk factors of macrosomia. The data were analyzed using the SPSS software. Results: 59 cases of macrosomia were found in 500 living births. The results showed that the frequency of macrosomia was 11.8%. 69.5% of the neonates were male and 30.5% were female. Maternal risk factors were mother's age at pregnancy, mother's obesity (BMI>=30, weight gain more than 18 kg during pregnancy, history of diabetes mellitus, history of macrosomia, prolonged gestational age, and multiparity (parity>=5. There was no significant relationship between mother's job and macrosomia. Conclusion: The prevalence of macrosomia in Khorramabad was high (11.8%. Preventing pregnancy in mothers over 35 years of age by contraception ways, preventing maternal obesity before pregnancy, and control of blood glucose during pregnancy by suitable diet and insulin therapy are recommended to prevent macrosomia.

    In 3 to 8% of pregnancies there are preeclampsia, and it is considered an irreversible disease that affects several organs, and causes injuries in fetus and mother alike. To identify maternal risk factors related to low birth weight in preterm newborns born at Hospital de Ginecología-Pediatría con Medicina Familiar no. 31 from IMSS, at Mexicali, BC, Mexico. Case-control study (1:2 ratio) made in 114 prematures (38 cases and 76 controls) who were evaluated for socioeconomic and biological maternal risk factors influencing low birth weight in preterm newborns. Odds ratio and confidence intervals of 95% were used to calculate epidemiologic correlation, and logistic regression to specific importance of risks. Preeclampsia persists as a risk factor for low birth weight: OR 3.16 (95% CI 3.15-8.40, p = 0.00). In logistic regression meaningful variables were: preeclampsia 5.27 (95% CI 1.45-19.14, p = 0.01), and in premature newborn: thrombocytopenia 6.0 (95% CI 1.2-11.2, p = 0.00), and neonatal sepsis 4.31 (95% CI 1.73-10.70, p = 0.00). Preeclampsia was the major risk factor related to low birth weight and was associated with thrombocytopenia in preterm newborn. Neonatal sepsis is secondary to low birth weight. We need to observe and obey prenatal care of pregnant women in our hospital to reduce negative impact of low birth weight in preterm newborns.

    To examine the value of combining cervical length and maternal characteristics in a prolonged-pregnancy clinic in the prediction of the probability of firstly, spontaneous onset of labor within the subsequent 10 days and secondly, the need for Cesarean section. This was a prospective study of women with singleton pregnancies attending an ultrasound-based prolonged-pregnancy clinic at 40 + 4 to 41 + 6 weeks of gestation. The policy was to delay induction of labor by 7-10 days unless there was evidence of a specific medical or obstetric indication or the mother wanted earlier delivery. The measurement of cervical length was not given to the obstetrician, midwife or patient. Regression analysis was used to determine which of the following factors had a significant contribution in predicting induction of labor: maternal age, body mass index (BMI), ethnic origin, parity and cervical length. Regression analysis was also used to determine which of the factors amongst the maternal characteristics, onset of labor and cervical length provided significant prediction of Cesarean section. We examined 2316 pregnancies but we excluded from further analysis 452 (19.5%) cases because iatrogenic delivery was carried out within the subsequent 6 days, including 427 cases of induction of labor (340 at the request of the mother and 87 for medical indications) and 25 cases of Cesarean section. In the remaining 1864 cases there was spontaneous onset of labor and delivery within 10 days in 1536 (82.4%) and induction of labor in 7-10 days in 328 (17.6%). The rate of Cesarean section was 15.2% (233 of 1536) in those with spontaneous onset of labor and 36.0% (118 of 328) in those whose labor was induced. Regression analysis demonstrated that in the prediction of induction of labor there were significant contributions from cervical length, BMI, parity and gestational age, and in the prediction of Cesarean section there were significant contributions from onset of labor, cervical length, BMI

    Cleft lip and palate, the most common developmental deformity, is seen worldwide and the etiology involves a combination of genetic and environmental factors. The purpose of this study was to determine the maternal risk factors associated with the development of cleft lip and cleft palate. We conducted a case control study at the Women's Hospital in Culiacan, Mexico. Medical records were analyzed, including patients who delivered babies with and without cleft lip and cleft palate from January 2010 to December 2015. Multiple variables were analyzed, including gestational age, weight at birth, the use of folic acid and multivitamins during pregnancy, smoking, alcohol abuse, the use of recreational drugs, history of sexually transmitted infections, marital status, socioeconomic status, education, and nutritional status. We found that the maternal risk factors with the strongest association for the development of cleft lip and cleft palate were the following: patients who were not taking folic acid during pregnancy [OR 3.27, 95% CI 1.32-8.09], P=0.00; patients who were not taking vitamin supplementation during pregnancy [OR 2.6, 95% CI 1.19-7.27], P=0.02; smoking during pregnancy [OR 2.05, 95% CI 1.23-3.41], P=0.01; and alcohol abuse during pregnancy [OR 1.90, 95% CI 1.17-3.08], P=0.03. The main risk factors associated with the development of cleft lip and cleft palate in a Mexican population at the Women's hospital in Culiacan, Sinaloa, Mexico were smoking, alcohol abuse, and patients not taking folic acid and multivitamins during pregnancy.

    Autism spectrum disorder (ASD) affecting about 1% of all children is associated, in addition to complex genetic factors, with a variety of prenatal, perinatal, and postnatal etiologies. In addition, ASD is often an important clinical presentation of some well-known genetic syndromes in human. We discuss these syndromes as well as the role of the more important prenatal factors affecting the fetus throughout pregnancy which may also be associated with ASD. Among the genetic disorders we find Fragile X, Rett syndrome, tuberous sclerosis, Timothy syndrome, Phelan-McDermid syndrome, Hamartoma tumor syndrome, Prader-Willi and Angelman syndromes, and a few others. Among the maternal diseases in pregnancy associated with ASD are diabetes mellitus (PGDM and/or GDM), some maternal autoimmune diseases like antiphospholipid syndrome (APLS) with anti-β2GP1 IgG antibodies and thyroid disease with anti-thyroid peroxidase (TPO) antibodies, preeclampsia and some other autoimmune diseases with IgG antibodies that might affect fetal brain development. Other related factors are maternal infections (rubella and CMV with fetal brain injuries, and possibly Influenza with fever), prolonged fever and maternal inflammation, especially with changes in a variety of inflammatory cytokines and antibodies that cross the placenta and affect the fetal brain. Among the drugs are valproic acid, thalidomide, misoprostol, and possibly SSRIs. β2-adrenergic receptor agonists and paracetamol have also lately been associated with increased rate of ASD but the data is too preliminary and inconclusive. Associations were also described with ethanol, cocaine, and possibly heavy metals, heavy smoking, and folic acid deficiency. Recent studies show that heavy exposure to pesticides and air pollution, especially particulate matter PM2.5 and PM10) during pregnancy is also associated with ASD. Finally, we have to remember that many of the associations mentioned in this review are only partially proven, and not

    Rapid migration in Latin America is settling rural women and their families next to those of urban origin in sprawling urban settings. Those born and reared in rural areas bring with them knowledge and skills learned and adapted to rural areas; those same skills may be maladaptive in urban areas. Hypothesized is that urban women of rural origin are more likely to have poorer health outcomes for themselves and their children than lifelong urban counterparts. Identification of specific risk factors affecting child and/or maternal health status in peri-urban barrios can assist health workers to target limited resources to those least likely to access available services.

    Corticotropin-releasing factor (CRF) binding protein (CRF-BP) is a secreted protein that acts to bind and limit the activity of the neuropeptides, CRF and urocortin (Ucn) 1. We previously selected for high maternal defense (protection of offspring) in mice and found CRF-BP to be elevated in the CNS of selected mice. We also previously determined that both CRF and Ucn 1 are potent inhibitors of offspring protection when administered centrally. Thus, elevated CRF-BP could promote defense by lim...

    Brain-derived neurotrophic factor (BDNF) is a neurotrophin essential for neuronal survival and differentiation. We examined the concentration of BDNF in cord serum from newborns exposed to methylmercury (MeHg) and polychlorinated biphenyls (PCB) in utero by maternal consumption of whale meat....... The cohort consisted of 395 singleton births (206 boys and 189 girls), gestational age ranging from 38 to 42 weeks. Serum BDNF was measured by sandwich ELISA. Maternal smoking habits and other relevant factors were obtained by interviewing the mothers. The exposure to MeHg was estimated from Hg...... concentrations in cord blood, whereas exposure to PCB was estimated based on maternal serum concentrations. Only MeHg exposure affected the serum BDNF, which decreased in a concentration-dependent manner in girls born to nonsmoking mothers. Maternal smoking significantly increased BNDF in girls but not in boys...

    Evolutionary change in developmental mode in sea urchins is closely tied to an increase in maternal provisioning. We examined the oogenic modifications involved in production of a large egg by comparison of oogenesis in congeneric sea urchins with markedly different sized oocytes and divergent modes of development. Heliocidaris tuberculata has small eggs (95 microm diameter) and the ancestral mode of development through feeding larvae, whereas H. erythrogramma has large eggs (430 microm diameter) and highly modified non-feeding lecithotrophic larvae. Production of a large egg in H. erythrogramma involved both conserved and divergent mechanisms. The pattern and level of vitellogenin gene expression is similar in the two species. Vitellogenin processing is also similar with the gonads of both species incorporating yolk protein from coelomic and hemal stores into nutritive cells with subsequent transfer of this protein into yolk granules in the developing vitellogenic oocyte. Immunocytology of the eggs of both Heliocidaris species indicates they incorporate similar levels of yolk protein. However, H. erythrogramma has evolved a highly divergent second phase of oogenesis characterised by massive deposition of non-vitellogenic material including additional maternal protein and lipid. Maternal provisioning in H. erythrogramma exhibits recapitulation of the ancestral vitellogenic program followed by a novel oogenic phase with hypertrophy of the lipogenic program being a major contributor to the increase in egg size.

    Full Text Available Objective. To identify care-related and maternal risk factors for the antenatal nondetection of IUGR. Methods. In this hospital-based case-control study we compared antenatally undetected IUGR neonates (cases to detected IUGR neonates (controls. Data were collected using newborn documentation sheets and standardized personal interviews with the mothers. We calculated antenatal detection rates and used uni- and multivariable logistic regression models to assess the association of antenatal nondetection of IUGR and maternal and care-related factors. Results. A total of 161 neonates from three hospitals were included in the study. Suboptimal fetal growth was identified antenatally in n=77 pregnancies while in n=84 it was not detected antenatally (antenatal detection rate: 47.8%. Severity of IUGR, maternal complications, and a Doppler examination during the course of pregnancy were associated with IUGR detection. We did not find statistically significant differences regarding parental socioeconomic status and maternal migration background. Conclusions. In our study, about half of all pregnancies affected by suboptimal growth remained undetected. Future in-depth studies with larger study populations should further examine factors that could increase antenatal detection rates for IUGR.

    Genetic factors influence stressor-provoked monoamine changes associated with anxiety and depression, but such effects might be moderated by early life experiences. To assess the contribution of maternal influences in determining adult brain monoamine responses to a stressor, strains of mice that were either stressor-reactive or -resilient (BALB/cByJ and C57BL/6ByJ, respectively) were assessed as a function of whether they were raising their biological offspring or those of the other strain. As adults, offspring were assessed with respect to stressor-provoked plasma corticosterone elevations and monoamine variations within discrete stressor-sensitive brain regions. BALB/cByJ mice demonstrated poorer maternal behaviors than C57BL/6ByJ dams, irrespective of the pups being raised. In response to a noise stressor, BALB/cByJ mice exhibited higher plasma corticosterone levels and elevated monoamine turnover in several limbic and hypothalamic sites. The stressor-provoked corticosterone increase in BALB/cByJ mice was diminished among males (but not females) raised by a C57BL/6ByJ dam. Moreover, increased prefrontal cortical dopamine utilization was attenuated among BALB/cByJ mice raised by a C57BL/6ByJ dam. These effects were asymmetrical as a C57BL/6ByJ mice raised by a BALB/cByJ dam did not exhibit increased stressor reactivity. It appears that stressors influence multiple neurochemical systems that have been implicated in anxiety and affective disorders. Although monoamine variations were largely determined by genetic factors, maternal influences contributed to stressor-elicited neurochemical changes in some regions, particularly dopamine activation within the prefrontal cortex.

    This study aimed to assess empirically the influence of individual and community (neighbourhood) factors on the use of maternal health care services in India through three outcomes: utilization of full antenatal care (ANC) services, safe delivery and utilization of postnatal care services. Data were from the third round of the National Family Health Survey (2005-06). The study sample constituted ever-married women aged 15-49 from 29 Indian states. Multilevel logistic regression analysis was performed for the three outcomes of interest accounting for individual- and community-level factors associated with the use of maternal health care services. A substantial amount of variation was observed at the community level. About 45%, 51% and 62% of the total variance in the use of full ANC, safe delivery and postnatal care, respectively, could be attributed to differences across the community. There was significant variation in the use of maternal health care services at the individual level, with socioeconomic status and mother's education being the most prominent factors associated with the use of maternal health care services. At the community level, urban residence and poverty concentration were found to be significantly associated with maternal health care service use. The results suggest that an increased focus on community-level interventions could lead to an increase in the utilization of maternal health care services in India.

    Full Text Available Environmental exposures that occur in utero and during early life may contribute to the development of childhood asthma through alteration of the human microbiome. The objectives of this study were to estimate the cumulative effect and relative importance of environmental exposures on the risk of childhood asthma.We conducted a population-based birth cohort study of mother-child dyads who were born between 1995 and 2003 and were continuously enrolled in the PRIMA (Prevention of RSV: Impact on Morbidity and Asthma cohort. The individual and cumulative impact of maternal urinary tract infections (UTI during pregnancy, maternal colonization with group B streptococcus (GBS, mode of delivery, infant antibiotic use, and older siblings at home, on the risk of childhood asthma were estimated using logistic regression. Dose-response effect on childhood asthma risk was assessed for continuous risk factors: number of maternal UTIs during pregnancy, courses of infant antibiotics, and number of older siblings at home. We further assessed and compared the relative importance of these exposures on the asthma risk. In a subgroup of children for whom maternal antibiotic use during pregnancy information was available, the effect of maternal antibiotic use on the risk of childhood asthma was estimated.Among 136,098 singleton birth infants, 13.29% developed asthma. In both univariate and adjusted analyses, maternal UTI during pregnancy (odds ratio [OR] 1.2, 95% confidence interval [CI] 1.18, 1.25; adjusted OR [AOR] 1.04, 95%CI 1.02, 1.07 for every additional UTI and infant antibiotic use (OR 1.21, 95%CI 1.20, 1.22; AOR 1.16, 95%CI 1.15, 1.17 for every additional course were associated with an increased risk of childhood asthma, while having older siblings at home (OR 0.92, 95%CI 0.91, 0.93; AOR 0.85, 95%CI 0.84, 0.87 for each additional sibling was associated with a decreased risk of childhood asthma, in a dose-dependent manner.

    Full Text Available Cesarean section must be justified only when benefits outweigh harm to the mother and fetus. The impact of Cesarean section on maternal and child health and its high cost compared with vaginal birth represent a public health problem. Cesarean section rate is increasing globally and reported to be 25 - 30% in recent studies . Several factors contribute to this increase , but repeat CS stands as the most relevant factor and contribute to about 29% of performed CS. One of the strategies proposed to reduce the CS rate is to increase the number of trials of labor among women who had previous one lower segment cesarean section. However , concern still remains r egarding associated maternal or neonatal complications and factors that lead to success or failure of VBAC. So , we undertook this study to evaluate the factors affecting success of VBAC. AIMS AND OBJECTIVE: To study maternal and fetal outcomes associated w ith trial of vaginal birth after cesarean section and to evaluate factors associated with its success. MATERIALS AND METHODS : It is an Observational prospective study performed on 100 partu rients in the department of OBG, in Mamata General Hospital , K hammam , Andhra Pradesh. Patients with previous one lower segment Cesarean section and a single fetus with cephalic presentation without cephalo - pelvic disproportion were included in the study. These women were given a trial for vaginal birth with observati on during labor by a partogram and external fetal cardiotocography. RESULTS: Vaginal birth was successful in 50%. Repeat Cesarean section was done in the other 50% due to suspicious scar (62% , fetal distress (24% and failure to progress (14%. Scar Ruptu re occurred in (6% , postpartum hemorrhage in (4% , neonatal incubation in (10% and the neonatal mortality was (2%.

    Full Text Available OBJECTIVE: To evaluate complications in pregnant women with sickle cell disease, especially those leading to maternal death or near miss (severe obstetric complications. METHODS: A prospective cohort of 104 pregnant women registered in the Blood Center of Belo Horizonte (Hemominas Foundation was followed up at high-risk prenatal units. They belonged to Group I (51 hemoglobin SS and three hemoglobin S/ß0-thalassemia or Group II (49 hemoglobin SC and one hemoglobin S/ß+-thalassemia. Both groups had similar median ages. Predictive factors for 'near miss' or maternal death with p-value = 0.25 in the univariate analysis were included in a multivariate logistic model (significance set for p-value = 0.05. RESULTS: Group I had more frequent episodes of vaso-occlusive crises, more transfusions in the antepartum and postpartum, and higher percentage of preterm deliveries than Group II. Infections and painful crises during the postpartum period were similar in both the groups. The mortality rate was 4.8%: three deaths in Group I and two in Group II. One-third of the women in both the groups experienced near miss. The most frequent event was pneumonia/acute chest syndrome. Alpha-thalassemia co-inheritance and ß-gene haplotypes were not associated with near miss or maternal death. In multivariate analysis predictors of near miss or death were parity above one and baseline red blood cell macrocytosis. In Group I, baseline hypoxemia (saturation < 94% was also predictive of near miss or death. CONCLUSION: One-third of pregnant women had near miss and 4.8% died. Both hemoglobin SS and SC pregnant women shared the same risk of death or of severe complications, especially pulmonary events.

    Observational studies suggest that including men in reproductive health interventions can enhance positive health outcomes. A randomized controlled trial was designed to test the impact of involving male partners in antenatal health education on maternal health care utilization and birth preparedness in urban Nepal. In total, 442 women seeking antenatal services during second trimester of pregnancy were randomized into three groups: women who received education with their husbands, women who received education alone and women who received no education. The education intervention consisted of two 35-min health education sessions. Women were followed until after delivery. Women who received education with husbands were more likely to attend a post-partum visit than women who received education alone [RR = 1.25, 95% CI = (1.01, 1.54)] or no education [RR = 1.29, 95% CI = (1.04, 1.60)]. Women who received education with their husbands were also nearly twice as likely as control group women to report making >3 birth preparations [RR = 1.99, 95% CI = (1.10, 3.59)]. Study groups were similar with respect to attending the recommended number of antenatal care checkups, delivering in a health institution or having a skilled provider at birth. These data provide evidence that educating pregnant women and their male partners yields a greater net impact on maternal health behaviors compared with educating women alone.

    Interaction between nucleus and cytoplasm has been focused in the field of animal embryonic development, in which study of maternal factors is required positively. Β-Catenin, an important maternal factor in early embryogenesis, has been analyzed in its expression pattern and functions in this paper. We have cloned goldfish β-Catenin cDNA gene and compared it with zebrafish β-Catenin cDNA. High homology was found in cDNA and in amino acid sequences between them, 93% (2227/2384 bp) and 98.5% (768/780 aa) respectively. The expression pattern of β-Catenin by in situ hybridization and the roles of β-Catenin on embryonic development by co-injection of anti-sense RNA and reporter gene, EGFP have been investigated in the whole process of goldfish embryonic development. The results suggest that β-Catenin presents dynamic distribution, mainly locates at body axis, dorsal tissues, head and tail structures after being fertilized. The loss of β-Catenin activity would cause serious destruction of embryo in dorsal tissues and in anteroposterior axes, and leads embryos to die before larva get hatched.

    The relationship between maternal work status, other socio-economic factors, and incidence of diarrhoea among children was studied using the Bangladesh Demographic and Health Survey (DHS) 1994 data. This study showed that 12.4% of children had suffered from diarrhoea in the two weeks preceding the survey. Of the women in the sample, 12% were working. Logistic regression analysis revealed that children of working mothers were 65% more likely to have had diarrhoea than children of non-working mothers. We also found that children of women who work seasonally were 8% less likely to have had diarrhoea than children of women who work all year. Women's higher education was found to be one of the important determinants related to childhood diarrhoea. Religion and ownership of land also appeared to be important factors affecting the incidence of diarrhoea in early childhood.

    Full Text Available Increased adiposity and unhealthy lifestyle augment the risk for type 2 diabetes in children with familial predisposition. Insulin resistance (IR is an excellent clinical marker for identifying children at high risk for type 2 diabetes. This study was conducted to investigate parental, physiological, behavioral and socio-economic factors related to IR in Korean children. This study is a cross-sectional study using data from 111 children aged 7 years and their parents. Homeostasis model assessment of insulin resistance (HOMA-IR was calculated using fasting glucose and insulin level as a marker of IR. All children’s adiposity indices (r = 0.309–0.318, all P-value = 0.001 and maternal levels of fasting insulin (r = 0.285, P-value = 0.003 and HOMA-IR (r = 0.290, P-value = 0.002 were positively correlated with children’s HOMA-IR level. There was no statistical difference of children’s HOMA-IR level according to children’s lifestyle habits and socioeconomic status of families. An increase of 1 percentage point in body fat was related to 2.7% increase in children’s HOMA-IR (P-value < 0.001 and an increase of 1% of maternal level of HOMA-IR was related to 0.2% increase in children’s HOMA-IR (P-value = 0.002. This study shows that children’s adiposity and maternal IR are positively associated with children’s IR.

    Full Text Available AbstractBackground: Macrosomia is a term applied to newborns with a birth weight of 4000 gr or above. Perinatal mortality and morbidity is increased in fetal macrosomia. Clavicular fracture, injury to brachial plexus, and hypoglycemia are important side effects. Mother’s age, body mass index of mother, weight gain in pregnancy, mother’s height, diabetes, history of macrocosmic delivery, gestational age, parity, and fetal sex are factors causing macrosomia. The purpose of this cross-sectional study was to evaluate the frequency and risk factors of macrosomia in Asalian hospital of Khorramabad in the summer of 2010. Methods: The data collection instrument was a questionnaire containing 10 variables as the risk factors of macrosomia. The data were analyzed using the SPSS software.Results: 59 cases of macrosomia were found in 500 living births. The results showed that the frequency of macrosomia was 11.8%. 69.5% of the neonates were male and 30.5% were female. Maternal risk factors were mother's age at pregnancy, mother's obesity (BMI>=30, weight gain more than 18 kg during pregnancy, history of diabetes mellitus, history of macrosomia, prolonged gestational age, and multiparity (parity>=5. There was no significant relationship between mother's job and macrosomia.Conclusion: The prevalence of macrosomia in Khorramabad was high (11.8%. Preventing pregnancy in mothers over 35 years of age by contraception ways, preventing maternal obesity before pregnancy, and control of blood glucose during pregnancy by suitable diet and insulin therapy are recommended to prevent macrosomia.

    To develop a model for prediction of spontaneous delivery before 34 weeks based on maternal factors, placental perfusion and function at 11-13 weeks' gestation. Two groups of studies: first, screening study of maternal characteristics, serum pregnancy-associated plasma protein-A (PAPP-A), free β-human chorionic gonadotrophin (β-hCG) and uterine artery pulsatility index (PI). Second, case-control studies of maternal serum or plasma concentration of placental growth factor (PlGF), placental protein 13 (PP13), a disintegrin and metalloprotease 12 (ADAM12), inhibin-A and activin-A. Regression analysis was used to develop a model for the prediction of spontaneous early delivery. Spontaneous early delivery occurred in 365 (1.1%) of the 34 025 pregnancies. A model based on maternal factors could detect 38.2% of the preterm deliveries in women with previous pregnancies at or beyond 16 weeks and 18.4% in those without, at a false positive rate (FPR) of 10%. In the preterm delivery group, compared with unaffected pregnancies there were no significant differences in the markers of placental perfusion or function, except for PAPP-A which was reduced. Patient-specific risk of preterm delivery is provided by maternal factors and obstetric history. Placental perfusion and function at 11-13 weeks are not altered in pregnancies resulting in spontaneous early delivery. Copyright © 2011 John Wiley & Sons, Ltd.

    Full Text Available To assess the relationship between maternal UTI during pregnancy and neonatal UTI.This cross-sectional study included eighty neonates referred to Ali-e-Asghar Hospital, Tehran, Iran, in 2011. The participants were divided into the study (with diagnosis of UTI; n = 40 and the control (without this type of infection; n = 40 groups. The mothers were asked about the history of UTI during pregnancy, and if the response was positive, the trimester in which UTI had occurred. Urinalysis and urine culture were carried out for all neonates.Overall, 14.9% of neonates had mothers with a positive history of UTI during their pregnancy (4.4%, 6.1%, and 4.4% during the 1(st, 2(nd, and 3(rd trimesters, respectively. A significant relationship was detected between the occurrence of UTI in neonates and maternal UTI, so that the overall prevalence of UTI among neonates of affected mothers was significantly higher than that observed among non-infected mothers (30.0% versus 6.8%; p = 0.001. Maternal UTI resulted in 5.9-fold increased risk of neonatal UTI. In UTI group, the most common bacterial etiologies of UTI were Escherichia coli (65.9%, followed by Klebsiella (14.6% and Staphylococci (9.8%.Our findings confirmed the association between the history of UTI in mother and occurrence of UTI in neonate, emphasizing to pay more attention for assessing and managing UTI in neonates in order to reduce the related complications.

    This study was undertaken to determine the risk factors for maternal deaths in unplanned or unbooked obstetric admissions to the intensive care unit of a tertiary health centre. Hospital records of unbooked obstetric admissions to the intensive care unit of the hospital from January 1997 to December 2006 were retrospectively reviewed. Data collected included patients' demographics, diagnosis, duration of stay in the ICU and patient outcome. The intensive care unit records showed that there were 25 unbooked obstetric admissions. Major diagnoses for unplanned admissions to the ICU were preeclampsia/eclampsia (41.1%), obstetric haemorrhage (37.5%), and respiratory distress (12.5%). There were 12 deaths (48%). Organ dysfunction on admission, massive blood loss and late presentation were the risk factors for mortality. The high maternal mortality was mainly due to limited supply of blood products and inadequate prenatal care resulting in disease severity.

    Full Text Available Background Maternal depression may be a risk factor for childhood trauma (CT, with resultant offspring development of mood disorders (MD in adult life. Objective To verify the relationship between maternal depression (as a risk factor for childhood trauma and mood disorders in young adults. Methods The sample was composed of 164 young adults and their mothers. Maternal depression was identified through the Mini International Neuropsychiatric Interview (M.I.N.I.. Mood Disorders in the young adults were confirmed with the Structured Interview for the DSM-IV (SCID, whereas the CT was evaluated using the Childhood Trauma Questionnaire (CTQ. Results In the group of young adults with MD, individuals who had depressed mothers presented higher mean scores of CT in comparison to the ones who did not have mothers with Depression (p < 0.005. Childhood trauma was also associated with lower social classes (p < 0.005. In the group of young adults without MD, the only variable that was associated with CT was the young adult’s (not current work (p < 0.005. Discussion Maternal depression was considered to be a risk factor for CT and MD in young adults. Thus, preventing and treating maternal psychiatric disorders may diminish the risk of offspring childhood trauma, and, consequently, avoid negative effects in the offspring’s adult life.

  7. Why are women so intelligent? The effect of maternal IQ on childhood mortality may be a relevant evolutionary factor.

    2010-03-01

    Humans are an unusual species because they exhibit an economic division of labour. Most theories concerning the evolution of specifically human intelligence have focused either on economic problems or sexual selection mechanisms, both of which apply more to men than women. Yet while there is evidence for men having a slightly higher average IQ, the sexual dimorphism of intelligence is not obvious (except at unusually high and low levels). However, a more female-specific selection mechanism concerns the distinctive maternal role in child care during the offspring's early years. It has been reported that increasing maternal intelligence is associated with reducing child mortality. This would lead to a greater level of reproductive success for intelligent women, and since intelligence is substantially heritable, this is a plausible mechanism by which natural selection might tend to increase female intelligence in humans. Any effect of maternal intelligence on improving child survival would likely be amplified by assortative mating for IQ by which people tend to marry others of similar intelligence - combining female maternal and male economic or sexual selection factors. Furthermore, since general intelligence seems to have the functional attribute of general purpose problem-solving and more rapid learning, the advantages of maternal IQ are likely to be greater as the environment for child-rearing is more different from the African hunter-gatherer society and savannah environment in which ancestral humans probably evolved. However, the effect of maternal IQ on child mortality would probably only be of major evolutionary significance in environments where childhood mortality rates were high. The modern situation is that population growth is determined mostly by birth rates; so in modern conditions, maternal intelligence may no longer have a significant effect on reproductive success; the effect of female IQ on reproductive success is often negative. Nonetheless, in the

    This study examines whether maternal vitamin D deficiency is a risk factor for infantile autism disease (IAD). We used epidemiologic data seasonal variation of birth rates and prevalence of IAD for cohorts born before 1985. For seven studies reporting spring-to-summer excess birth rates for IAD, the season progressed from broad near 30 degrees N latitude, spring/summer in midlatitudes, to winter at the highest latitude. Also, using data from 10 studies, we found a strong effective latitudinal (related to wintertime solar ultraviolet B radiation) increase in IAD prevalence. These findings are consistent with maternal vitamin D deficiency's being a risk factor for IAD, possibly by affecting fetal brain development as well as possibly by affecting maternal immune system status during pregnancy. Further investigation of this hypothesis is warranted.

    Early environmental factors can modulate the development of the hypothalamic-pituitary-adrenal (HPA) axis response to stress, together with subsequent brain functions and emotional behaviors. Two rat strains, Sprague-Dawley (SD) and Fischer 344 (F344), are known to exhibit differences in HPA axis reactivity and anxiety behavior in response to restraint stress in adulthood. To investigate the contribution of maternal influences in determining HPA axis and behavioral responses to stress, a cross-fostering study was performed using stress-resilient (SD) or stress-susceptible (F344) strains. We found that SD rats adopted by either an SD (in-fostered) or an F344 (cross-fostered) dam and F344 rats adopted by an SD dam (cross-fostered) showed a suppression of the HPA axis response following 14 days of repeated restraint stress. In contrast, F344 rats adopted by an F344 dam (in-fostered) did not show such HPA axis habituation. We also found that F344 rats adopted by an F344 dam showed increased anxiety-related behaviors in social interaction and novelty-suppressed feeding tests as a result of the 14 days of restraint stress, while SD rats adopted by either an SD or an F344 dam and F344 rats adopted by an SD dam showed normal anxiety-related behaviors under the same experimental conditions. These results suggest that while genetic differences between SD and F344 strains account for some of the variations in stress vulnerability, maternal factors also contribute. (c) 2009 Elsevier B.V.

    1999-05-01

    Maternally acting selfish genes, termed 'Medea' factors, were found to be widespread in wild populations of Tribolium castaneum collected in Europe, North and South America, Africa and south-east Asia, but were rare or absent in populations from Australia and the Indian subcontinent. We detected at least four distinct genetic loci in at least two different linkage groups that exhibit the Medea pattern of differential mortality of genotypes within maternal families. Although each M factor tested had similar properties of maternal lethality to larvae and zygotic self-rescue, M factors representing distinct loci did not show cross-rescue. Alleles at two of these loci, M1 and M4, were by far the most prevalent, M4 being the predominant type. M2 and M3 were each found only once, in Pakistan and Japan, respectively. Although M1 could be genetically segregated from M4 and maintained as a purified stock, the M1 factor invariably co-occurred with M4 in field populations, whereas M4 usually occurred in the absence of other Medea factors. The dominant maternal lethal action of M1 could be selectively inactivated (reverted) by gene-knockout gamma irradiation with retention of zygotic rescue activity.

    Despite global initiatives to lower rates of maternal death, barriers to safe motherhood persist, particularly in socially and economically marginalized communities. This article describes the risks that women in Honduran Miskito villages encounter during pregnancy and childbirth. Ethnographic data are used to examine emic understandings of the underlying causes of maternal death. Participant observation, four community discussions, individual interviews with 218 women and five midwives, and a maternal mortality survey were conducted during November 2004 through November 2005. Case studies are drawn from the 55 death histories collected during the survey to illustrate the factors that contribute to maternal mortality. Community members identified poverty, gender inequality, witchcraft, and sorcery as major threats to safe motherhood. All of these factors influence women's health-related behaviors; and therefore, each issue deserves attention from public health officials. Designing appropriate interventions to improve maternal health depends on understanding the forces that increase women's vulnerability during pregnancy and childbirth. Local perspectives of risk, even when they diverge from biomedical understandings, point to specific needs, issues to address, and avenues for effective intervention.

    Full Text Available Abstract Background Maternal near-miss (MNM audits are considered a useful approach to improving maternal healthcare. The aim of this study was to evaluate the factors associated with maternal near-miss cases in childbirth and the postpartum period in Brazil. Methods The study is based on data from a nationwide hospital-based survey of 23,894 women conducted in 2011–2012. The data are from interviews with mothers during the postpartum period and from hospital medical files. Univariate and multivariable logistic regressions were performed to analyze factors associated with MNM, including estimation of crude and adjusted odds ratios and their respective 95 % confidence intervals (95 % CI. Results The estimated incidence of MNM was 10.2/1,000 live births (95 % CI: 7.5–13.7. In the adjusted analyses, MNM was associated with the absence of antenatal care (OR: 4.65; 95 % CI: 1.51–14.31, search for two or more services before admission to delivery care (OR: 4.49; 95 % CI: 2.12–9.52, obstetric complications (OR: 9.29; 95 % CI: 6.69–12.90, and type of birth: elective C-section (OR: 2.54; 95 % CI: 1.67–3.88 and forceps (OR: 9.37; 95 % CI: 4.01–21.91. Social and demographic maternal characteristics were not associated with MNM, although women who self-reported as white and women with higher schooling had better access to antenatal and maternity care services. Conclusion The high proportion of elective C-sections performed among women in better social and economic situations in Brazil is likely attenuating the benefits that could be realized from improved prenatal care and greater access to maternity services. Strategies for reducing the rate of MNM in Brazil should focus on: 1 increasing access to prenatal care and delivery care, particularly among women who are at greater social and economic risk and 2 reducing the rate of elective cesarean section, particularly among women who receive services at private maternity facilities, where

    Fibroblast growth factor-23 (FGF23), a phosphate(Phos)-regulating hormone, is abnormally elevated in hypophosphataemic syndromes and an elevated FGF23 is a predictor of mortality in kidney disease. Recent findings suggest iron deficiency as a potential mediator of FGF23 expression and murine studies have shown in utero effects of maternal iron deficiency on offspring FGF23 and phosphate metabolism. Our aim was to investigate the impact of maternal iron status on infant FGF23 and mineral metabolites over the first 2years of life. Infants born to mothers with normal (NIn=25,) and low (LIn=25) iron status during pregnancy, from a mother-infant trial (ISRCTN49285450) in rural Gambia, West Africa, had blood and plasma samples analysed at 12, 24, 52, 78 and 104weeks (wk) of age. Circulating intact-FGF23 (I-FGF23), Phos, total alkaline phosphatase (TALP) and haemoglobin (Hb) decreased and estimated glomerular filtration rate increased over time [all P≤0.0001)]. C-terminal-FGF23 (C-FGF23) and TALP were significantly higher in LI compared with NI, from 52wk for C-FGF23 [Beta coefficient (SE) 18.1 (0.04) %, P=0.04] and from 24wk for TALP [44.7 (29.6) U/L, P=0.04]. Infant Hb was the strongest negative predictor of C-FGF23 concentration [-21% (4%) RU/mL, P≤0.0001], Phos was the strongest positive predictor of I-FGF23 [32.0(3.9) pg/mL, P≤0.0001] and I-FGF23 did not predict C-FGF23 over time [-0.5% (0.5%), P=0.3]. In conclusion, this study suggests that poor maternal iron status is associated with a higher infant C-FGF23 and TALP but similar I-FGF23 concentrations in infants and young children. These findings further highlight the likely public health importance of preventing iron deficiency during pregnancy. Whether or not children who are born to iron deficient mothers have persistently high concentrations of these metabolites and are more likely to be at risk of impaired bone development and pre-disposed to rickets requires further research.

    The current UK Department of Health advice is to introduce solid foods to infants at around 6 months of age, when the infant is showing signs of developmental readiness for solid foods. However, many mothers introduce solid foods before this time, and for a wide variety of reasons, some of which may not promote healthy outcomes. The aim of the current study was to examine infant and maternal characteristics associated with different reasons for introducing solid foods. Seven hundred fifty-six mothers with an infant aged 6-12 months old completed a questionnaire describing their main reason for introducing solid foods alongside demographic questions, infant weight, gender, breast/formula feeding and timing of introduction to solid foods. The majority of mothers introduced solid foods for reasons explicitly stated in the Department of Health advice as not signs of readiness for solid foods. These reasons centred on perceived infant lack of sleep, hunger or unsettled behaviour. Maternal age, education and parity, infant weight and gender and breast/formula feeding choices were all associated with reasons for introduction. A particular association was found between breastfeeding and perceiving the infant to be hungrier or needing more than milk could offer. Male infants were perceived as hungry and needing more energy than female infants. Notably, signs of readiness may be misinterpreted with some stating this reason for infants weaned prior to 16 weeks. The findings are important for those working to support and educate new parents with the introduction of solid foods in understanding the factors that might influence them.

    Multiple behavioral and health outcomes, including internalizing symptoms, may be predicted from prenatal maternal anxiety, depression, or stress. However, not all children are affected, and those that are can be affected in different ways. Here we test the hypothesis that the effects of prenatal anxiety are moderated by genetic variation in the child's brain-derived neurotrophic factor (BDNF) gene, using the Avon Longitudinal Study of Parents and Children population cohort. Internalizing symptoms were assessed from 4 to 13 years of age using the Strengths and Difficulties Questionnaire (n = 8,584); a clinical interview with the adolescents was conducted at age 15 years (n = 4,704). Obstetric and psychosocial risk and postnatal maternal symptoms were included as covariates. Results show that prenatal maternal anxiety predicted internalizing symptoms, including with the diagnostic assessment at 15 years. There was a main effect of two BDNF polymorphisms (rs6265 [val66met] and rs11030104) on internalizing symptoms up to age 13. There was also genetic moderation of the prenatal anxiety effect by different BDNF polymorphisms (rs11030121 and rs7124442), although significant effects were limited to preadolescence. The findings suggest a role for BDNF gene-environment interactions in individual vulnerability to the effects of prenatal anxiety on child internalizing symptoms.

    To identify maternal and antenatal factors associated with stillbirths and neonatal deaths in rural Bangladesh. A prospective cohort study is being conducted to evaluate a maternal and child nutrition program in rural Bangladesh. Cases were all stillbirths and neonatal deaths that occurred in the cohort between March 7, 2011 and December 30, 2011. Verbal autopsies were used to determine cause of death. For each case, four controls were randomly selected from cohort members alive at age 3-months. Multivariable logistic regression was used to identify factors associated with these deaths. Overall, 112 adverse pregnancy outcomes (44 stillbirths, 19/1,000 births; 68 neonatal deaths, 29/1,000 live births) were reported. Of the stillbirths 25 (56.8%) were fresh. The main causes of neonatal death were birth asphyxia (35%), sepsis (28%) and preterm birth (19%). History of bleeding during pregnancy was the strongest risk factor for stillbirths (adjusted odds ratio 22.4 [95% confidence interval 2.5, 197.5]) and neonatal deaths (adjusted odds ratio 19.6 [95% confidence interval 2.1, 178.8]). Adequate maternal nutrition was associated with decreased risk of neonatal death (adjusted odds ratio 0.4 [95% confidence interval 0.2, 0.8]). Identifying high-risk pregnancies during gestation and ensuring adequate antenatal and obstetric care needs to be a priority for any community-based maternal and child health program in similar settings.

    The maternal contribution of gene products enables embryos to initiate their developmental program in the absence of zygotic gene expression. In Caenorhabditis elegans, maternal CDC-25.1 levels are tightly regulated to promote early cell divisions, while stabilization of this phosphatase by gain-of-function mutations gives rise to intestinal-specific hyperplasia. To identify regulators of CDC-25.1 levels and/or function, we performed a modifier screen of the cdc-25.1(gf)-dependent hyperplasia. One of the isolated suppressor mutants possesses a donor splice site mutation in prp-8, a key splicing factor of the U5-specific snRNP. prp-8(rr40) produces aberrant prp-8 splice variants that generate C-terminal truncations at the expense of wild-type prp-8. Levels of maternal transcripts are reduced, including cdc-25.1, while zygotic transcripts appear unperturbed, suggesting a germ-line-specific role for this splicing factor in regulating the splicing, and consequently, the steady-state levels of maternal transcripts. Using a novel feeding RNAi strategy we found that only a subset of splicing factors suppress cdc-25.1(gf), suggesting that they too may play specific roles in germ-line spliceosome function. In humans, mutations in the corresponding hPrp8 C-terminal domain result in retinitis pigmentosa, a retinal-specific disorder. Intriguingly, despite affecting the general splicing apparatus, both human and C. elegans show tissue-specific defects resulting from mutations in this key splicing component. Our findings suggest that in addition to its important regulatory function in the C. elegans germ line, prp-8(rr40) may provide further insight into the etiology of this splicing-associated human disorder.

    The p53 family and its regulatory pathway play an important role as regulators of developmental processes, limiting the propagation of aneuploid cells. Its dysfunction or imbalance can lead to pathological abnormalities in humans. The aim of this study was to evaluate the effect of maternal polymorphisms TP53 c.215G>C (P72R), TP73 4 c.-30G>A and 14 c.-20C>T, MDM2 c.14+309T>G (SNP309), MDM4 c.753+572C>T and USP7 c.2719-234G>A as risk factors for Down Syndrome (DS) birth. A case-control study was conducted with 263 mothers of DS children and 196 control mothers. The distribution of these genotypic variants was similar between case and control mothers. However, the combined alleles TP53 C and MDM2 G, and TP53 C and USP7 A increased the risk of having offspring with DS (OR = 1.84 and 1.77; 95% CI; P < 0.007 and 0.018, respectively). These results suggest that, although the individual polymorphisms were not associated with DS birth, the effect of the combined genotypes among TP53, MDM2 and USP7 genes indicates a possible role of TP53 and its regulatory pathway as a risk factor for aneuploidy.

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

    Maternal prepregnancy obesity has been linked to the offspring's risk for subsequent asthma. We determined whether maternal obesity is associated with increased risk of wheezing phenotypes early in life. We used data on 1107 mother-child pairs from two birth cohorts from the INMA-INfancia y Medio Ambiente project. Maternal height was measured and prepregnancy weight self-reported at enrolment (on average at 13.7 ± 2 weeks of gestation). Maternal prepregnancy body mass index was categorised as underweight, normal, overweight and obese according to WHO recommendations. Information on child's wheezing was obtained through questionnaires up to the age of 14 (± 1) months. Wheezing was classified as infrequent (<4 reported wheezing episodes) or frequent (≥ 4 episodes). Weight and length of infants were measured by trained study staff at 14.6 (± 1) months of age and weight-for-length z-scores computed. Although maternal obesity did not increase the risk of the child to have any or infrequent wheezing, children of obese mothers were more likely to have frequent wheezing than children of normal-weight mothers (11.8% vs. 3.8%; P = 0.002). In fully adjusted multinomial logistic regression models, including infants' weight-for-length z-scores and other covariates, maternal prepregnancy obesity was associated with increased risk of frequent [adjusted relative risk (RR) 4.18, 95% confidence interval (CI) 1.55, 11.3] but not infrequent (RR 1.05 [95% CI 0.55, 2.01]) wheezing in their children. Maternal prepregnancy obesity is independently associated with an increased risk of frequent wheezing in the infant by the age of 14 months. These findings add evidence on the potential effects of in utero exposures on asthma-related phenotypes. © 2012 Blackwell Publishing Ltd.

    This study was conducted to determine factors that promote success in an introductory college computer science course and to determine what, if any, differences appear between genders on those factors. The model included math background, attribution for success/failure, self-efficacy, encouragement, comfort level in the course, work style preference, previous programming experience, previous non-programming computer experience, and gender as possible predictive factors for success in the computer science course. Subjects included 105 students enrolled in an introductory computer science course. The study revealed three predictive factors in the following order of importance: comfort level (with a positive influence), math background (with a positive influence), and attribution to luck (with a negative influence). No significant gender differences were found in these three factors. The study also revealed that both a formal class in programming (which had a positive correlation) and game playing (which had a negative correlation) were predictive of success. The study revealed a significant gender difference in game playing with males reporting more experience with playing games on the computer than females reported.

    Full Text Available Introduction & Objective: The Ministry of Health and Medical Education of Iran established maternity facilities in order to provide a safe delivery and reduce deliveries at home in rural areas. However, a few of deliveries in Kohgilouyeh and Boyerahmad province took place in these centers. Therefore, the aim of this study was to determine the delivery status and factors influencing the pregnant women’s tendency to choose the place of delivery. Materials & Methods: This descriptive study was carried out on 747 participants in the rural areas that were covered by maternity facilities in the first three months of 1384. Data were collected by a self-structured questionnaire whose validity and reliability had been determined previously. Data of age, education level, parietal status, antenatal cares, decision-maker for the place of delivery, geographical access to maternity facility centers and the cause of avoidance of referring to the centers were determined asking the women. Data were analyzed by SPSS software and using X2 statistical test. Results: The results showed that overall 31% (230 cases of deliveries took place at home and 51% (384 cases at hospital, but only 18% (133 cases of deliveries took place at maternity facility centers. There was a significant difference in antenatal education by midwives between women who delivered at home and those that delivered at maternity facility centers, showing that more educated women have managed to deliver at the maternity facility centers (p < 0.001. 58% of mothers had selected their delivery place by themselves, but in others the delivery place was selected by their mothers, mothers-in-law, their husbands, etc. Almost 79% (181cases of mothers who delivered at home announced that geographical access (long distance to the maternity facility was major problem.

    Epidural analgesia is the most effective method for pain relief during labor. This 10-year exploratory descriptive study on factors underlying women's decisions to request or refuse labor epidural analgesia (LEA) was carried out at a level III maternity hospital in Antananarivo, Madagascar. All patients underwent a pre-anesthesia check-up (PAC) between 32 and 34 weeks of amenorrhea. During the PAC, a questionnaire was administered to determine socio-economic aspects, level of education, and knowledge about labor pain and LEA. In addition, LEA was proposed and patients were asked to explain their reasons for accepting or refusing the procedure. The purpose of this report was to describe the factors underlying acceptance or refusal of EA by nulliparous women. A total of 41 nulliparous women were included. Fourteen (34.14%) accepted LEA and 27 (63.86%) refused. Mean age was 27 years in the acceptance group and 25 years in the refusal group. No patient had good knowledge about LEA. Nulliparous women that accepted EA had a higher socio-economic level, expected stronger labor pain, were better informed about EA, and expressed greater confidence in medical care. In addition to economic aspects, the main reasons for refusing EA involved fear and family background.

    In developing countries, severe undernutrition in early childhood is associated with increased mortality and morbidity, and 10-40% of hospital admissions. The current study aimed to elicit maternal perceptions of factors that contribute to severe undernutrition among children in a rural Kenyan community in order to identify appropriate and acceptable targeted interventions. The study consisted of 10 focus group discussions (FGDs) of between eight and ten mothers each, in a rural coastal community in Kenya. A grounded theory approach was used to analyse the FGD data. In all FGDs 'financial constraints' was the main reason given for severe undernutrition of children. The mothers reported the additional factors of inadequate food intake, ill health, inadequate care of children, heavy workload for mothers, inadequate control of family resources by women and a lack of resources for generating income for the family. The mothers also reported their local cultural belief that severe malnutrition was due to witchcraft and the violation of sexual taboos. The mothers in the study community recognised multiple aetiologies for severe undernutrition. A multidisciplinary approach is needed address the range of issues raised and so combat severe undernutrition. Suggested interventions include poverty alleviation, medical education and psychosocial strategies. The content and approach of any program must address the need for variability, determined by individual and local needs, concerns, attitudes and beliefs.

    Poor maternal nutrition inhibits muscle development and postnatal muscle growth. Satellite cells are myogenic precursor cells that contribute to postnatal muscle growth, and their activity can be evaluated by the expression of several transcription factors. Paired-box (Pax)7 is expressed in quiescent and active satellite cells. MyoD is expressed in activated and proliferating satellite cells and myogenin is expressed in terminally differentiating cells. Disruption in the expression pattern or timing of expression of myogenic regulatory factors negatively affects muscle development and growth. We hypothesized that poor maternal nutrition during gestation would alter the in vitro temporal expression of MyoD and myogenin in satellite cells from offspring at birth and 3 months of age. Ewes were fed 100% or 60% of NRC requirements from day 31±1.3 of gestation. Lambs from control-fed (CON) or restricted-fed (RES) ewes were euthanized within 24 h of birth (birth; n=5) or were fed a control diet until 3 months of age (n=5). Satellite cells isolated from the semitendinosus muscle were used for gene expression analysis or cultured for 24, 48 or 72 h and immunostained for Pax7, MyoD or myogenin. Fusion index was calculated from a subset of cells allowed to differentiate. Compared with CON, temporal expression of MyoD and myogenin was altered in cultured satellite cells isolated from RES lambs at birth. The percent of cells expressing MyoD was greater in RES than CON (P=0.03) after 24 h in culture. After 48 h of culture, there was a greater percent of cells expressing myogenin in RES compared with CON (P0.05). In satellite cells from RES lambs at 3 months of age, the percent of cells expressing MyoD and myogenin were greater than CON after 72 h in culture (Psatellite cells of the offspring, which may reduce the pool of myoblasts, decrease myoblast fusion and contribute to the poor postnatal muscle growth previously observed in these animals.

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

Using a structured questionnaire, we conducted face- to-face interviews with women at antenatal clinics between 1998 and 1999 in Hualien City. One year later, we took the outcome of pregnancy from medical records and birth certificates from the Public Health Bureau of Hualien County. Of the 1,128 single live births, 6.8% had low birth weight (LBW using the World Health Organization cut-off of 2,500 g. LBW was more common in teenage ( 30 years, first-time, and unmarried mothers; those with basic/intermediate educational attainment; and residents of aboriginal districts. Teenage pregnancies were more likely than those in adults to be unplanned, and such mothers had smoking or alcohol-drinking behavior. Prevention of teenage pregnancy is crucial to lower LBW rates in eastern Taiwan. For adult mothers, basic or intermediate educational attainment, residence in an aboriginal district, and first-term pregnancy were significant factors associated with LBW, after adjustment for other psychosocial attributes, such as psychologic distress and poor family support. Thus, we should pay more attention when caring for pregnant women with such sociodemographic characteristics, and ensure that they have adequate prenatal care and can adopt a healthy lifestyle.

  1. Maternal smoking and alcohol consumption during pregnancy as risk factors for sudden infant death.

    A population based case control study was conducted to examine alcohol consumption and maternal smoking during pregnancy and the risk of SIDS in an Irish population. Each SIDS case (n = 287) was compared with control infants (n = 832) matched for date and place of birth for infants born from 1994 to 2001. Conditional logistic regression was used to investigate differences between Cases and Controls establishing Odds Ratio\\'s (OR) and 95% Confidence Intervals (CI). Mothers who smoked were 3 times more likely to have a SIDS Case, and a dose response effect was apparent, with mothers smoking 1-10 cigarettes\\/day OR 2.93 (CI 1.50-5.71), and those smoking > 10 cigarettes\\/day OR 4.36 (CI 2.50-7.61). More Case mothers consumed alcohol during pregnancy than Control mothers and, within drinkers, the amount of alcohol consumed was also greater (p < 0.05). A dose response with frequency of drinking was apparent. The adjusted odds ratio for those consuming alcohol in all three trimesters was 3.59 (CI:1.40-9.20). Both of these risk factors are modifiable and need to be incorporated into antenatal education from a SIDS point of view.

    The purpose of the study was to assess the influence of socioeconomic risk factors, food security, health, and key anthropometric measures on body mass index (BMI) in a group of teenagers from Medellin, Colombia, in the third trimester of pregnancy. A cross-sectional study was carried out with 294 pregnant teenagers. Data were analyzed using bivariate and multivariate logistic regression analysis. Pregnant teenagers whose families earned less than one minimum wage were more likely to have low weight (OR = 5.8; 95%CI: 1.97-16.8). Age under 15 years was associated with a fourfold increase in low gestational weight. Arm and calf circumference greater than 24cm and 32cm, respectively, were associated with a 94% reduction in low gestational weight (arm circumference: OR = 0.1; 95%CI: 0.0-0.2) (calf circumference: OR = 0.1; 95%CI: 0.0-0.2). In conclusion, low income and young age were associated with low gestational weight. Arm and calf circumference correlated with maternal weight.

    Full Text Available Mice harboring a mutation in the gene encoding gastric intrinsic factor (Gif, a protein essential for the absorption of vitamin B12/cobalamin (Cbl, have potential as a model to explore the role of vitamins in infection. The levels of Cbl in the blood of Giftm1a/tm1a mutant mice were influenced by the maternal genotype, with offspring born to heterozygous (high Cbl, F1 mothers exhibiting a significantly higher serum Cbl level than those born to homozygous (low Cbl, F2 equivalents. Low Cbl levels correlated with susceptibility to an infectious challenge with Salmonella enterica serovar Typhimurium or Citrobacter rodentium, and this susceptibility phenotype was moderated by Cbl administration. Transcriptional and metabolic profiling revealed that Cbl deficient mice exhibited a bioenergetic shift similar to a metabolic phenomenon commonly found in cancerous cells under hypoxic conditions known as the Warburg effect, with this metabolic effect being exacerbated further by infection. Our findings demonstrate a role for Cbl in bacterial infection, with potential general relevance to dietary deficiency and infection susceptibility.

    Full Text Available Abstract Background There is much interest in the possibility that perinatal factors may influence the risk of disease in later life. We investigated the influence of maternal and perinatal factors on subsequent hospital admission for asthma in children. Methods Analysis of data from the Oxford record linkage study (ORLS to generate a retrospective cohort of 248 612 records of births between 1970 and 1989, with follow-up to records of subsequent hospital admission for 4 017 children with asthma up to 1999.

    To examine socio-demographic factors associated with maternal help-seeking for child developmental concerns in a longitudinal birth cohort study. An understanding of these factors is critical to improving uptake of services to maximise early identification and intervention for developmental concerns. A birth cohort was recruited from the post-natal wards of two teaching hospitals and through community nurses in South Western Sydney, Australia, between November 2011 and April 2013. Of the 4047 mothers approached, 2025 consented to participate (response rate = 50%). Socio-demographic and service use information was collected after the child's birth and when the child was 18 months of age. Sources of help were divided into three categories (formal health services, other formal services and informal supports) and compound variables were created by summing the number of different sources identified by mothers. Significantly more sources of help were intended to be used and/or actually accessed by mothers born in Australia, whose primary language was English, with higher levels of education and annual household income, and among mothers of first-born children. Developmental concerns are known to increase with increased psychosocial adversity. Our findings of reduced intent to access and use of services by socio-economically disadvantaged families and those from culturally and linguistically diverse backgrounds suggests that an inverse care effect is in operation whereby those children with the greatest health needs may have the least access to services. Possible explanations for this, and recommendations for improving service accessibility for these populations through targeted and culturally appropriate services, are discussed. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

  6. Pathways involved in gut mucosal barrier dysfunction induced in adult rats by maternal deprivation: corticotrophin-releasing factor and nerve growth factor interplay

    OpenAIRE

    2007-01-01

    Neonatal maternal deprivation (NMD) increases gut paracellular permeability (GPP) through mast cells and nerve growth factor (NGF), and modifies corticotrophin-releasing factor (CRF) and corticosterone levels. CRF, corticosterone and mast cells are involved in stress-induced mucosal barrier impairment. Consequently, this study aimed to specify whether corticosteronaemia and colonic expression of both preproCRF and CRF are modified by NMD, and to determine if altered expression may participate...

    RNA interference (RNAi) high-content screening (HCS) enables massive parallel gene silencing and is increasingly being used to reveal novel connections between genes and disease-relevant phenotypes. The application of genome-scale RNAi relies on the development of high quality HCS assays. The Z' factor statistic provides a way to evaluate whether or not screening run conditions (reagents, protocols, instrumentation, kinetics, and other conditions not directly related to the test compounds) are optimized. Z' factor, introduced by Zhang et al., ( 1) is a dimensionless value that represents both the variability and the dynamic range between two sets of sample control data. This paper describe a new extension of the Z' factor, which integrates bioinformatics RNAi non-target compounds for screening quality assessment. Currently presented Z' factor is based on positive and negative control, which may not be sufficient for RNAi experiments including oligonucleotides (oligo) with lack of knock-down. This paper proposes an algorithm which extends existing algorithm by using additional controls generetaed from on-target analysis.

    Full Text Available Abstract Background The aim of this study was to determine which behavioral factors to include in guidelines for the Japanese public to achieve an acceptable level of oral healthiness. The objective was to determine the relationship between oral health related behaviors and symptoms related to oral disease and tooth loss in a Japanese adult community. Methods Oral health status and lifestyle were investigated in 777 people aged 20 years and older (390 men and 387 women. Subjects were asked to complete a postal questionnaire concerning past diet and lifestyle. The completed questionnaires were collected when they had health examinations. The 15 questions included their preference for sweets, how many between-meal snacks they usually had per day, smoking and drinking habits, presence of oral symptoms, and attitudes towards dental visits. Participants were asked about their behaviors at different stages of their life. The oral health examinations included examination of the oral cavity and teeth performed by dentists using WHO criteria. Odds ratios were calculated for all subjects, all 10 year age groups, and for subjects 30 years or older, 40 years or older, 50 years or older, and 60 years or older. Results Frequency of tooth brushing (OR = 3.98, having your own toothbrush (OR = 2.11, smoking (OR = 2.71 and bleeding gums (OR = 2.03 were significantly associated with number of retained teeth in males.

    We sought to assess congruity between data abstracted from medical records with answers to self-administered questionnaires. This was a multicenter prospective nulliparous pregnancy cohort. A total of 1507 women enrolled. Analyses were reported for 1296 with medical record data and 3-month postpartum follow-up. There was near-perfect agreement (κ ≥ 0.80) between maternal report and abstracted data for reproductive history, induction/augmentation method, epidural/spinal analgesia, method of birth, perineal repair, infant birthweight, and gestation. Agreement was poor to moderate for maternal position in second stage and duration of pushing. Maternal report of pregnancy, labor, and birth factors was very reliable and considered more accurate in relation to maternal position in labor and birth, smoking, prior terminations, and miscarriages. Use of routine birthing outcome summaries may introduce measurement error as hospitals differ in their definitions and reporting practices. Using primary data sources (eg, partograms) with clearly defined prespecified criteria will provide the most accurate obstetric exposure and outcome data. Copyright © 2012 Mosby, Inc.

    Postpartum hemorrhage (PPH) is the leading cause of maternal mortality in Sub-Saharan-Africa (SSA). Although clinical guidelines treating PPH are available, their implementation remains a great challenge in resource poor settings. A better understanding of the factors associated with PPH maternal mortality is critical for preventing risk of hospital-based maternal death. The purpose of this study was thus to assess which factors contribute to maternal death occurring during PPH. The factors were as follows: women's characteristics, aspects of pregnancy and delivery; components of PPH management; and organizational characteristics of the referral hospitals in Senegal and Mali. A cross-sectional survey nested in a cluster randomized trial (QUARITE trial) was carried out in 46 referral hospitals during the pre-intervention period from October 2007 to September 2008 in Senegal and Mali. Individual and hospital characteristics data were collected through standardized questionnaires. A multivariable logistic mixed model was used to identify the factors that were significantly associated with PPH maternal death. Among the 3,278 women who experienced PPH, 178 (5.4%) of them died before hospital discharge. The factors that were significantly associated with PPH maternal mortality were: age over 35 years (adjusted OR = 2.16 [1.26-3.72]), living in Mali (adjusted OR = 1.84 [1.13-3.00]), residing outside the region location of the hospital (adjusted OR = 2.43 [1.29-4.56]), pre-existing chronic disease before pregnancy (adjusted OR = 7.54 [2.54-22.44]), prepartum severe anemia (adjusted OR = 6.65 [3.77-11.74]), forceps or vacuum delivery (adjusted OR = 2.63 [1.19-5.81]), birth weight greater than 4000 grs (adjusted OR = 2.54 [1.26-5.10]), transfusion (adjusted OR = 2.17 [1.53-3.09]), transfer to another hospital (adjusted OR = 13.35 [6.20-28.76]). There was a smaller risk of PPH maternal death in hospitals with gynecologist

    2008-06-15

    Liberalisation of the electricity market has led to Danish gas engine plants increasingly converting to the spot and regulating power markets. In order to offer regulating power, plants need to be able to start and stop the engines at the plants quickly. The liberalisation causes a considerable change of operation practice of the engines e.g. less full load operation hours /year. The project provides an inventory determining the scale of the emissions during the start and stop sequence as well as proposals for engine modifications aimed at reducing start/stop emissions. This report includes calculation of emission factors as well as an inventory of total emissions and reduction potentials. (au)

    AIMS: To investigate the relationship between levels of insulin-like growth factors 1 and 2 (IGF-1, IGF-2), and insulin-like growth factor binding protein 3 (IGFBP-3) in antenatal maternal serum and gestational age at delivery. METHODS: Prospective cohort study of 1650 low-risk Caucasian women in a London University teaching hospital. Maternal IGF-1, IGF-2 and IGFBP-3 were measured in maternal blood at booking and analyzed with respect to gestational age at delivery. RESULTS: There was no significant association between maternal IGF-1 or IGF-2 and preterm birth (PTB). A significant reduction in mean IGFBP-3 levels was noted with delivery <32 completed weeks (P=0.02). CONCLUSION: Maternal mean IGFBP-3 levels are significantly reduced in cases complicated by delivery <32 completed weeks.

    Lyophilization appears to be a viable method for storing human milk, assuring no microbiological contamination and preserving its health benefits and antibacterial properties. The aim of the study is to evaluate and compare the effects of different storage methods (lyophilization and freezing at -20°C and -80°C) and maternal factors (gestational length or time postpartum) upon the microbiological contents and bactericidal activity of human milk. The possible relation between bactericidal activity and the content of certain nutrients and functional components is also investigated. Microbiological content, bactericidal activity, sialic acid, and ganglioside contents, as well as protein, fat, and lactose concentrations were assessed in 125 human milk samples from 65 healthy donors in the Human Milk Bank of La Fe (Valencia, Spain). Lyophilization and storage at -80°C significantly reduced the content of mesophilic aerobic microorganisms and Staphylococcus epidermidis when compared with storage at -20°C. Bactericidal activity was not significantly modified by lyophilization when compared with freezing at either -20°C or -80°C. Bactericidal activity was not correlated with fat, protein, or lactose content, but was significantly correlated to ganglioside content. The bactericidal activity was significantly greater (P milk and in milk from women with term delivery than in milk from early lactation (days 1-7 postpartum) and milk from women with preterm delivery, respectively. Lyophilization and storage at -80°C of human milk yields similar results and are superior to storage at -20C with regard to microbial and bactericidal capacities, being a feasible alternative for human milk banks.

    Full Text Available Background: Neonatal jaundice, especially breast feeding jaundice is one of the most common causes of neonatal readmission during the first month of life. Breast feeding jaundice may be due to decreased milk intake with dehydration and/or reduced caloric intake.  The aim of this Study was to determine maternal risk factors of breast feeding jaundice in order to prevent it than before.Methods: This case- control study was performed at Bahrami University Hospital, Tehran, Iran and involved 75 term exclusively breast fed newborns admitted for hyperbilirubinemia, with a weight loss greater than 7%, with one positive lab data as: serum Na≥ 150meq/lit, urine specific gravity> 1012, serum urea≥ 40mgr/dl, without assigned cause for hyperbilirubinemia. They were compared with 75 matched controls with weight loss less than 7%, without dehydration and a known cause of hyperbilirubinemia.Results: In comparison with control group, in neonates with breast feeding jaundice, inappropriate feeding practice (P<0.033, delayed onset of lactation (P<0.0001, inverted nipple (P<0.001 were significantly higher. In our study, there was no significant difference between two groups in education level of mother, learning breast feeding practice before and after delivery, method of delivery (cesarean or vaginal delivery, primiparity or multiparity and use of supplements (water or glucose water.Conclusion: This study shows need for special attention and follows up of mothers and neonates at risk for breast feeding jaundice, especially those with inverted nipples or undergraduate for successful breast feeding. On the other hand this study shows encouraging mothers for early lactation especially in the first hour of life decreases the risk for this kind of jaundice.

    We examined whether polymorphisms in the methylenetetrahydrofolate dehydrogenase (MTHFD) and transcobalamin (TC) genes, which are involved in folate metabolism, affect maternal risk for Down syndrome. We investigated 76 Down syndrome mothers and 115 control mothers from Bengbu, China. Genomic DNA was isolated from the peripheral lymphocytes. Polymerase chain reaction and restriction fragment length polymorphism were used to examine the polymorphisms of MTHFD G1958A and TC C776G. The frequencies of the polymorphic alleles were 24.3 and 19.1% for MTHFD 1958A, 53.9 and 54.2% for TC 776G, in the case and control groups, respectively. No significant differences were found between two groups in relation to either the allele or the genotype frequency for both polymorphisms. However, when gene-gene interactions between these two polymorphisms together with previous studied C677T and A1298C polymorphisms in the methylenetetrahydrofolate reductase (MTHFR) gene were analyzed, the combined MTHFR 677CT/TT and MTHFD 1958AA/GA genotype was found to be significantly associated with the risk of having a Down syndrome child [odds ratio (OR) = 3.11; 95% confidence interval (95%CI) = 1.07-9.02]. In addition, the combined TC 776CG and MTHFR 677TT genotype increased the risk of having a child with Down syndrome 3.64-fold (OR = 3.64; 95%CI = 1.28-10.31). In conclusion, neither MTHFD G1958A nor TC C776G polymorphisms are an independent risk factor for Down syndrome. However, the combined MTHFD/MTHFR, TC/MTHFR genotypes play a role in the risk of bearing a Down syndrome child in the Chinese population.

    The Darwinian paradox of male homosexuality in humans is examined, i.e. if male homosexuality has a genetic component and homosexuals reproduce less than heterosexuals, then why is this trait maintained in the population? In a sample of 98 homosexual and 100 heterosexual men and their relatives (a total of over 4600 individuals), we found that female maternal relatives of homosexuals have higher fecundity than female maternal relatives of heterosexuals and that this difference is not found in female paternal relatives. The study confirms previous reports, in particular that homosexuals have more maternal than paternal male homosexual relatives, that homosexual males are more often later-born than first-born and that they have more older brothers than older sisters. We discuss the findings and their implications for current research on male homosexuality.

Over 30 % of the children were stunted, approximately 16 % were underweight, 4 % were wasted, approximately 18 % were overweight and 4 % were obese; 8 % were both overweight/obese and stunted. Maternal overweight and obesity, higher levels of maternal education, being a large or very large child at birth, and being stunted were each associated with higher odds of overweight and obesity among Kenyan children. Older children and large household size were each associated with lower odds of overweight and obesity among Kenyan children. The analysis demonstrates the presence of under- and overnutrition among Kenyan pre-school children and the importance of focusing on expanding efforts to prevent and treat malnutrition within this population. It also identifies some of the modifiable factors that can be targeted in these efforts.

    Recently, mental health problems (MHP) in school-aged children have become a global phenomenon. Yet, the number of children affected remains unclear in Indonesia, and the effects of mental health problems are of concern. The purpose of this study was to investigate the prevalence of MHP in school-aged children and its relationship to personal, maternal, and familial factors in Aceh province, Indonesia. Participants were 143 school-aged children with MHP and their mothers. They completed the Strengths and Difficulties Questionnaire, Social Competence Questionnaire, Brief Family Relationship Scale, Parental Stress Scale, Parent's Report Questionnaire, and Indonesian Version of the Beck Depression Inventory-II. Mainly, children were rated to have emotional symptoms by their mothers (37.8%). Factors such as academic competence, family relationships, and maternal parenting stress are related to MHP. Given the high prevalence of school-aged children that have emotional symptoms, child psychiatric mental health nurses should give special attention to assist them during their school years. Moreover, nurses should aim to improve family relationships and reduce maternal parenting stress. Copyright © 2016 Elsevier B.V. All rights reserved.

    Data from a prospective study of 548 children followed from birth to 4 years of age were analysed to determine whether maternal smoking during and/or after pregnancy affects children's neuropsychological development. The differences in mean developmental test scores between children whose mothers smoked and those of mothers who did not smoke were slight, with subscale scores only 2.4 to 4.1% lower in children whose mothers smoked. These differences were not statistically significant after adjustment for socio-economic status, quality of home environment and mother's intelligence, suggesting that the social and environmental factors are major confounders of the association of exposure to maternal smoking and neuropsychological development in childhood. In order to gain a better understanding of this area, more precise measures of exposure to environmental tobacco smoke and comprehensive consideration of confounders will be required.

    The aim of this study was to provide additional evidences on prognostic factors for infantile spasms and the possible role of a ketogenic diet. A retrospective analysis was performed for patients with infantile spasms who had been followed up for more than 6months between January 2000 and July 2012 at Samsung Medical Center (Seoul, Republic of Korea). We analyzed the association between possible prognostic factors and seizure/developmental outcomes. Sixty-nine patients were included in this study and their mean follow-up duration was 52.5 (9-147) months. In the patients who had been followed up for more than 2years, 53.6% (n=30/57) remained seizure-free at the last visit. Sixty patients (86.9%) showed developmental delay at last follow-up. Forty-two patients (60.9%) became spasm-free with one or two antiepileptic drugs, one patient with epilepsy surgery for a tumor, and seven patients with a ketogenic diet after the failure of two or more antiepileptic drugs. The etiology and age of seizure onset were the significant prognostic factors. In this study, about 60% of the patients became spasm-free with vigabatrin and topiramate. Ketogenic diet increased the rate by 10% in the remaining antiepileptic drug resistant patients. However, 86.9% of the patients showed developmental delay, mostly a severe degree. Early diagnosis and prompt application of treatment options such as antiepileptic drugs, a ketogenic diet or epilepsy surgery can improve outcomes in patients with infantile spasms.

    Socioeconomic inequalities in physical activity at the individual level are well reported. Whether inequalities in economic development and other macroenvironmental variables between countries are also related to physical activity at the country level is comparatively unstudied. We examined the relationship between country-level data on macroenvironmental factors (gross domestic product (GDP) per capita, public sector expenditure on health, percentage living in urban areas, and cars per 1000 population) with country-level physical activity prevalence obtained from previous pan-European studies. Studies that assessed leisuretime physical activity (n = 3 studies including 27 countries in adults, n = 2 studies including 28 countries in children) and total physical activity (n = 3 studies in adults including 16 countries) were analyzed separately as were studies among adults and children. Strong and consistent positive correlations were observed between country prevalence of leisure-time physical activity and country GDP per capita in adults (average r = 0.70; all studies, P G 0.05). In multivariate analysis, country prevalence of leisure-time physical activity among adults remained associated with country GDP per capita (two of three studies) but not urbanization or educational attainment. Among school-age populations, no association was found between country GDP per capita and country prevalence of leisure-time physical activity. In those studies that assessed total physical activity (which also includes occupational and transport physical activity), no association with country GDP per capita was observed. Clear differences in national leisure-time physical activity levels throughout Europe may be a consequence of economic development. Lack of economic development of some countries in Europe may make increasing leisure-time physical activity more difficult.

    The Canadian Perinatal Surveillance System has provided a comprehensive review of maternal mortality and severe maternal morbidity in Canada, and has identified several important limitations to existing national maternal data collection systems, including variability in the detail and quality of mortality data. The Canadian Perinatal Surveillance System report recommended the establishment of an ongoing national review and reporting system, as well as consistency in definitions and classifications of maternal mortality and severe maternal morbidity, in order to enhance surveillance of maternal mortality and severe maternal morbidity. Using review articles and studies that examined maternal mortality in general as opposed to maternal mortality associated with particular management strategies or conditions, maternal mortality and severe morbidity classifications, terminology, and comparative statistics were reviewed and employed to evaluate deficiencies in past and current methods of data collection and to seek solutions to address the need for enhanced and consistent national surveillance of maternal mortality and severe maternal morbidity in Canada.

    Full Text Available The paper presents the results of sociological study devoted to the evaluation of the social expectations of women associated with the realization of their right to maternity capital. Different social attitudes and intentions of 308 women who have two and more children with respect to realization of the program of the maternity capital were investigated. Characteristics of cognitive, emotional and behavioral readiness to participate in the governmental program of increasing fertility were assessed. The results confirm the adequacy and objectivity of the social expectations of women. They made the decision about the birth of a second child without taking into account the expected payment of the maternity capital (for 33.8% respondents maternity capital had “no meaning”; for 36.4% respondents it was just a “pleasant additional payment”. The reproductive behavior of women was based on family traditions (91.9% respondents were born in big families with two or more children and awareness of their personal responsibility for bearing and raising children (45.8% respondents were ready “for any difficulties for their children”, 23.1% respondents consider their children as “happiness and meaning of their lives”. However, 22.0% of women made their decision about the birth of the second child with expectations for the maternity capital. They were the women from the low-income families (29.6%. Promotion the childbirth in low-income families may lead to the increasing number of dysfunctional families and children who find themselves in difficult life situations. All this facts may lead to different social problems in the future.

    The role of fever in trauma patients remains unclear. Fever occurs as a response to release of cytokines and prostaglandins by white blood cells. Many factors, including trauma, can trigger release of these factors. To determine whether (1) fever in the first 48 hours is related to a favorable outcome in trauma patients and (2) fever is more common in patients with head trauma. Retrospective study of trauma patients admitted to the intensive care unit for at least 2 days. Data were analyzed by using multivariate analysis. Of 162 patients studied, 40% had fever during the first 48 hours. Febrile patients had higher mortality rates than did afebrile patients. When adjusted for severity of injuries, fever did not correlate with mortality. Neither the incidence of fever in the first 48 hours after admission to the intensive care unit nor the number of days febrile in the unit differed between patients with and patients without head trauma (traumatic brain injury). About 70% of febrile patients did not have a source found for their fever. Febrile patients without an identified source of infection had lower peak white blood cell counts, lower maximum body temperature, and higher minimum platelet counts than did febrile patients who had an infectious source identified. The most common infection was pneumonia. No relationship was found between the presence of fever during the first 48 hours and mortality. Patients with traumatic brain injury did not have a higher incidence of fever than did patients without traumatic brain injury. About 30% of febrile patients had an identifiable source of infection. Further studies are needed to understand the origin and role of fever in trauma patients. ©2015 American Association of Critical-Care Nurses.

    Repeated maternal separation of rat pups during the early postnatal period may affect brain-derived neurotrophic factor (BDNF) or neurons in brain areas that are compromised by chronic stress. In the present study, a highly significant increase in hippocampal BDNF protein concentration was found in adult rats that as neonates had been subjected to 180 min of daily separation compared with handled rats separated for 15 min daily. BDNF protein was unchanged in the frontal cortex and hypothalamus/paraventricular nucleus. Expression of BDNF mRNA in the CA1, CA3, or dentate gyrus of the hippocampus or in the paraventricular hypothalamic nucleus was not affected by maternal separation. All animals displayed similar behavioral patterns in a forced-swim paradigm, which did not affect BDNF protein concentration in the hippocampus or hypothalamus. Repeated administration of bromodeoxyuridine revealed equal numbers of surviving, newly generated granule cells in the dentate gyrus of adult rats from the 15 min or 180 min groups. The age-dependent decline in neurogenesis from 3 months to 7 months of age did not differ between the groups. Insofar as BDNF can stimulate neurogenesis and repair, we propose that the elevated hippocampal protein concentration found in maternally deprived rats might be a compensatory reaction to separation during the neonatal period, maintaining adult neurogenesis at levels equal to those of the handled rats.

    Placenta previa is associated with maternal hemorrhage, but most literature focuses on morbidity in the setting of placenta accreta. We aim to characterize maternal morbidity associated with previa and to define risk factors for hemorrhage. This is a secondary cohort analysis of the NICHD Maternal-Fetal Medicine Units Network Cesarean Section Registry. This analysis included all women undergoing primary Cesarean delivery without placenta accreta. About 496 women with previa were compared with 24,201 women without previa. Primary outcome was composite maternal hemorrhagic morbidity. Non-hemorrhagic morbidities and risk factors for hemorrhage were also evaluated. Maternal hemorrhagic morbidity was more common in women with previa (19 versus 7%, aRR 2.6, 95% CI 1.9-3.5). Atony requiring uterotonics (aRR 3.1, 95% CI 2.0-4.9), red blood cell transfusion (aRR 3.8, 95% CI 2.5-5.7), and hysterectomy (aRR 5.1, 95% CI 1.5-17.3) were also more common with previa. For women with previa, factors associated with maternal hemorrhage were pre-delivery anemia, thrombocytopenia, diabetes, magnesium use, and general anesthesia. Placenta previa is an independent risk factor for maternal hemorrhagic morbidity. Some risk factors are modifiable, but many are intrinsic to the clinical scenario.

    The purpose of this study was to explain the health promotion behavior of Chinese international students in Korea using a structural equation model including acculturation factors. A survey using self-administered questionnaires was employed. Data were collected from 272 Chinese students who have resided in Korea for longer than 6 months. The data were analyzed using structural equation modeling. The p value of final model is .31. The fitness parameters of the final model such as goodness of fit index, adjusted goodness of fit index, normed fit index, non-normed fit index, and comparative fit index were more than .95. Root mean square of residual and root mean square error of approximation also met the criteria. Self-esteem, perceived health status, acculturative stress and acculturation level had direct effects on health promotion behavior of the participants and the model explained 30.0% of variance. The Chinese students in Korea with higher self-esteem, perceived health status, acculturation level, and lower acculturative stress reported higher health promotion behavior. The findings can be applied to develop health promotion strategies for this population. Copyright © 2016. Published by Elsevier B.V.

    To examine the effect of maternal HIV infection, as well as other individual, family, and contextual factors on the mental health of inner-city, ethnic minority early adolescents. Participants included 220 HIV-negative early adolescents (10-14 years) and their mothers, half of whom were HIV-infected. Individual interviews were conducted regarding youth depression, anxiety, externalizing and internalizing behaviour problems, as well as a range of correlates of youth mental health guided by a modified version of Social Action Theory, a theoretical model of behavioral health. Although the HIV status of mothers alone did not predict youth mental health, youth knowledge of mother's HIV infection and mother's overall health were associated with worse youth mental health outcomes, as were contextual, self-regulation, and family interaction factors from our theoretical model. There is a need for family-based mental health interventions for this population, particularly focusing on parent-child relationships, disclosure, and youth self-esteem.

    Objective Angiogenic factors have been implicated in the pathophysiology of sepsis. In experimental models of sepsis (endotoxemia and/or cecal ligation puncture), there is increased expression of vascular endothelial growth factors (VEGF) and the administration of exogenous soluble VEGF receptor (sVEGFR)-1, an antagonist to VEGF, reduces morbidity and mortality. Moreover, a dramatic elevation in sVEGFR-1 has been demonstrated in human sepsis. Although a balance between angiogenic and anti-angiogenic factors is essential for feto-placental development, the changes of angiogenic factors during pregnancy in the context of infection have never been explored. Angiogenic factors also play crucial roles in the pathophysiology of preeclampsia. This study was conducted to determine if maternal plasma concentrations of placental growth factor (PlGF), sVEGFR-2 and soluble endoglin (sEng) change in pregnancies complicated by acute pyelonephritis (AP) compared to normal pregnancy and preeclampsia (PE). Study Design A case-control study was conducted in patients with AP, normal pregnant women (NP) and patients with PE (n=36 for each group) matched for gestational age. AP was diagnosed in the presence of fever (temperature ≥ 38°C), clinical signs of infection, and a positive urine culture for micro-organisms. Plasma concentrations of PlGF, sVEGFR-2 and sEng were determined by ELISA. The results of plasma sVEGFR-1 concentrations has previously been reported before, but were included in this study to provide a complete picture of the angiogenic/anti-angiogenic profiles. Serum concentrations of interleukin (IL)-1β, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12p70, IL-13, interferon (IFN)-γ, Granulocyte macrophage colony stimulating factor (GM-CSF), and tumor necrosis factor (TNF)-α were also determined using high sensitivity multiplexed immunoassays in patients with AP and NP. Results AP was associated with a lower median plasma concentration of PlGF and sVEGFR-2 than NP

    To investigate the overall incidence and risk factors for persistent pain and its interference with daily life after cesarean section. Prospective long-term follow-up study. Karolinska University Hospital, Stockholm, Sweden. 260 healthy women who underwent elective cesarean section. Information on demographics, medical history, postoperative pain and analgesic requirements was collected. A questionnaire consisting of the Brief Pain Inventory was posted at 3, 6 and 12 months after surgery. Women rated pain intensity as well as interference with factors related to general function and quality of life. The overall incidence and risk factors for persistent postoperative pain at three time points. Persistent pain was considered a secondary outcome. At 3, 6 and 12 months respectively 40, 27 and 22% of patients reported pain in one or more locations, in the surgical site as well as in other areas. A psychological indication, as well as a first cesarean section, increased the risk for pain at 3 months. Severe postoperative pain in the immediate postoperative period or undergoing a first cesarean section were significant independent risk factors for the development of persistent pain up to 6 months after cesarean section. Parameters related to quality of life were significantly impaired in women with persistent pain. Several factors, including severe postoperative pain, were shown to influence the risk for persistent pain after cesarean section. Long-term pain markedly affected women's wellbeing. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

  1. Maternal immune stimulation reduces both placental morphologic damage and down-regulated placental growth-factor and cell cycle gene expression caused by urethane: are these events related to reduced teratogenesis?

    Activation of the maternal immune system in mice decreased cleft palate caused by the chemical teratogen, urethane. Direct and indirect mechanisms for this phenomenon have been suggested, including maternal macrophages that cross the placenta to find and eliminate pre-teratogenic cells, or maternal immune proteins (cytokines) that cross placenta to alleviate or partially alleviate toxicant-mediated effects in the developing fetus. A third mechanism to explain improved fetal developmental outcome in teratogen-challenged pregnant mice might involve beneficial effects of immune stimulation on the placenta. In the present experiments, urethane treatment altered placental morphology and impaired placental function, the latter indicated by down-regulated activity of cell cycle genes and of genes encoding cytokines and growth factors. Maternal immune stimulation with either Freund's complete adjuvant (FCA) or interferon-gamma (IFNgamma) reduced morphologic damage to the placenta caused by urethane and normalized expression of several genes that were down-regulated by urethane. Urethane treatment also shifted placental cytokine gene expression toward a T cell helper 1 (Th1) profile, while immunostimulation tended to restore a Th2 profile that may be more beneficial to pregnancy and fetal development. These data suggest that the beneficial effects of maternal immune stimulation on fetal development in teratogen-exposed mice may, in part, result from improved placental structure and function.

  4. Maternal and fetal factors and placentation: implications for pre-eclampsia.

    Science.gov (United States)

    Huppertz, Berthold

    2014-07-01

    The etiology of preeclampsia is still mysterious and a source of a variety of hypotheses. Accordingly, there is a number of theories present today describing different pathways how this disorder may develop. The most cited hypothesis on the etiology of preeclampsia is based on an inadequate remodeling of uterine spiral arteries in the placental bed due to superficial trophoblast invasion followed by placental hypoxia. Since maternal blood into the placenta is only established after week 12 of gestation, an effect of a failure in arterial remodeling can only affect the placenta starting with the second trimester of pregnancy. Recent studies on early predictive biomarkers for preeclampsia (such as PP13, fetal hemoglobin and PIGF) have indicated that there are changes of the villous trophoblast already weeks before the onset of maternal blood flow into the placenta, i.e. during mid first trimester. Moreover, a number of studies has shown that in cases with impaired trophoblast invasion resulting in inadequate remodeling of uterine spiral arteries placental hypoxia does not occur. In all these studies where mostly indirect assessments of placental oxygen have been performed, a higher oxygen partial pressure within the placenta has been measured. This is in clear contrast to the old hypothesis where placental hypoxia is essential for the etiology of preeclampsia. New biomarkers from the maternal and/or fetal compartment for the early prediction of preeclampsia may help in identifying the real etiology of preeclampsia. We need to use this momentum to decipher the real causes of this syndrome.

    Placenta growth factor (PIGF), an angiogenic factor belonging to the vascular endothelial growth factor family, pregnancy-associated plasma protein A (PAPP-A) and free beta-human chorionic gonadotrophin (beta-hCG) were measured in maternal serum from 45 pregnancies with trisomy 21, 45 with trisomy 18 and 493 normal controls at 10-13 completed weeks of gestation. In the normal pregnancies maternal serum PIGF levels increased exponentially with gestation. The median multiple of the median (MoM) PIGF concentration in the trisomy 21 group (1.26 MoM) was significantly higher (ptrisomy 18 group the median PIGF was lower (0.889 MoM) but this did not quite reach significance (p=0.064). The corresponding median MoM values for PAPP-A were 1.00 MoM for the controls, 0.49 MoM for trisomy 21 and 0.16 MoM for trisomy 18. The median MoM values for free beta-hCG were 1.00 MoM for the controls, 2.05 MoM for trisomy 21 and 0.38 MoM for trisomy 18. In the control group there was a small but significant correlation of PIGF with free beta-hCG (r=+0.1024) and PAPP-A (r=+0.2288). In the trisomy 18 group there was a significant association between PIGF and free beta-hCG (r=+0.2629) but not with PAPP-A (r=+0.0038). In the trisomy 21 group there was a small but significant association with PAPP-A (r=+0.1028) but not with free beta-hCG (r=+0.0339). The separation of affected and unaffected pregnancies in maternal serum PIGF is small, and therefore it is unlikely that measurement of PIGF would improve screening for these abnormalities provided by the combination of fetal nuchal translucency and maternal serum PAPP-A and free beta-hCG.

    Demand-side financing (DSF) interventions, including cash transfers and vouchers, have been introduced to promote maternal and newborn health in a range of low- and middle-income countries. These interventions vary in design but have typically been used to increase health service utilisation by offsetting some financial costs for users, or increasing household income and incentivising 'healthy behaviours'. This article documents experiences and implementation factors associated with use of DSF in maternal and newborn health. A secondary analysis (using an adapted Supporting the Use of Research Evidence framework - SURE) was performed on studies that had previously been identified in a systematic review of evidence on DSF interventions in maternal and newborn health. The article draws on findings from 49 quantitative and 49 qualitative studies. The studies give insights on difficulties with exclusion of migrants, young and multiparous women, with demands for informal fees at facilities, and with challenges maintaining quality of care under increasing demand. Schemes experienced difficulties if communities faced long distances to reach participating facilities and poor access to transport, and where there was inadequate health infrastructure and human resources, shortages of medicines and problems with corruption. Studies that documented improved care-seeking indicated the importance of adequate programme scope (in terms of programme eligibility, size and timing of payments and voucher entitlements) to address the issue of concern, concurrent investments in supply-side capacity to sustain and/or improve quality of care, and awareness generation using community-based workers, leaders and women's groups. Evaluations spanning more than 15 years of implementation of DSF programmes reveal a complex picture of experiences that reflect the importance of financial and other social, geographical and health systems factors as barriers to accessing care.

    Full Text Available Risk factors can lead to disturbance of all areas of a child's development, and thus also of language acquisition and to problems in early relationships between parent and child. In the event of multiple risk factors, as it is often the case amongst people living in poverty, the burden of risks and therefore the probability of developmental disturbance rises (Laucht, Esser & Schmidt, 1998; Wustmann, 2004.In the present study a sample amongst families living in poverty (San Pedro, Ecuador was compared with a sample taken from middle-class families (Quito, Ecuador. An examination was carried out whether there was a varying number of risk factors and whether there were differences in the language competence of the child as well as in the mother's sensitivity. There was a further examination of whether there was a correlation between maternal sensitivity and communicative competences. The results indicate a negative influence of risk conditions on the language acquisition of the children and on the intuitive and sensitive maternal competences. In the risk group, the results showed a preponderance of delays and disturbances in language development of the children. The mothers from the risk sample group displayed less sensitivity than the control group. There was also a correlation between maternal sensitivity and individual areas of competence. This study shows that it is necessary to ascertain the delays in children's language acquisition and mother-child interaction, particularly amongst families with serious burdens and multiple risk factors. Ascertaining these developmental risks can be used for prevention or intervention which can reduce the risk of negative consequences and aid positive adaptation.

    Promoting awareness of rights is a value-based process that entails a different way of thinking and acting, which is at times misunderstood or deemed as aspirational. Guided by the SURE framework, we undertook a secondary analysis of 26 documents identified by an earlier systematic review on promoting awareness of rights to increase use of maternity care services. We thematically analysed stakeholder experiences and implementation factors across the diverse initiatives to derive common elements to guide future efforts. Interventions that promote awareness of rights for maternal health varied in nature, methodological orientation, depth and quality. Materials included booklets, posters, pamphlets/ briefs and service standards/charters. Target populations included women, family members, communities, community structures, community-based and non governmental organizations, health providers and administrators, as well as elected representatives. While one initiative only focused on raising awareness, most were embedded within larger efforts to improve the accountability and responsiveness of service delivery through community monitoring and advocacy, with a few aiming to change policies and contest elections. Underlying these action oriented forms of promoting awareness of rights, was a critical consciousness and attitudinal change gained through iterative capacity-building for all stakeholders; materials and processes that supported group discussion and interaction; the formation or strengthening of community groups; situational analysis to ensure adaptation to local context; facilitation to ensure common ground and language across stakeholders; and strategic networking and alliance building across health system levels. While many positive experiences are discussed, few challenges or barriers to implementation are documented. The limited documentation and poor quality of information found indicate that while various examples of promoting awareness of rights for

    Full Text Available This study aimed to investigate the role of maternal polymorphisms, as well as their risk genotypes combinations of MTR A2756G, MTRR A66G, CBS 844ins68, and RFC A80G, involved in folate/homocysteine metabolism, as possible risk factors for Down syndrome (DS in Southern Brazil. A case-control study was conducted with 239~mothers of DS children and 197 control mothers. The investigation of polymorphisms was performed by PCR and PCR-RFLP. The distribution of genotypic variants was similar in both groups when they were analyzed separately. An investigation of combined risk genotypes showed that the risk of having a DS child for one, two or three risk genotypes was 6.23, 6.96 and 5.84 (95%CI 1.48–26.26; 1.69–28.66; 1.37–24.86, respectively. The combined MTRR 66G and MTHFR 677T alleles were significantly more common among mothers of children with DS than among control mothers (OR 1.55; IC 95% 1.03–2.35. The results show that individual polymorphisms studied in this work are not associated with DS; however, the effects of the combined risk genotypes among MTR, MTRR, CBS and RFC genes are considered maternal risk factors for DS offspring in our population.

    Neonatal Sepsis is one of the most common reasons for admission to neonatal units in developing countries. It is also a major cause of mortality in both developed and developing countries. Identification of the common bacteria and risk factors causing such infections and their susceptibility patterns will provide necessary information for timely intervention. This study was carried out to determine the bacteriological profile and associated risk factors of neonatal sepsis in Paropakar Maternity and Women's hospital. A cross-sectional prospective study was conducted among neonates suspected of neonatal sepsis. Blood culture was performed and organisms were identified and antibiotic susceptibility was carried out with standard microbiological methods. Data were analysed by using SPSS. Ver. 16 software. The positive yield of blood culture was 21%. The most common isolates were Staphylococcus epidermidis, E. coli, Staphylococcus aureus, Klebsiella pneumoniae and Pseudomonas spp. In Antibiotic susceptibility pattern Gentamycin showed the highest sensitivity to all types of isolated organisms. Vancomycin sensitivity was highest for Gram positive organism and Ciprofloxacin was most effective for Gram negative organisms isolated. Ampicillin and Amoxycillin were the least effective drug. Multiple drug resistance was observed in 77.15% of isolates. Prematurity, low birth weight and maternal pyrexia before delivery were found to be strongly associated with neonatal sepsis. Gram positive organisms were more prevalent than gram negative organisms.

    Full Text Available While every individual of Bemisia tabaci (Hemiptera: Aleyrodidae harbors the primary symbiont (P-symbiont Portiera, the infection frequencies of the six secondary symbionts (S-symbionts including Hamiltonella, Arsenophonus, Cardinium, Wolbachia, Rickettsia and Fritschea vary greatly among different populations. To characterize the factors influencing the infection dynamics of the six S-symbionts in B. tabaci, gene-specific PCR were conducted to screen for the presence of the P-symbiont Portiera and the six S-symbionts in 61 (17 B and 44 Q biotypes field populations collected from different plant species and locations in China. All individuals of the 61 populations hosted the P-symbiont Portiera, but none of them harbored Arsenophonus and Fritschea. The presence and infection rates of Hamiltonella, Cardinium, Rickettsia, Wolbachia and their co-infections Rickettsia + Hamiltonella (RH, Rickettsia + Cardinium (RC, Hamiltonella + Cardinium (HC and Rickettsia + Hamiltonella + Cardinium (RHC varied significantly among the 61 field populations; and the observed variations can be explained by biotypes, sexes, host plants and geographical locations of these field populations. Taken together, at least three factors including biotype, host plant and geographical location affect the infection dynamics of S-symbionts in B. tabaci.

  16. Insulin Like Growth Factor 2 Expression in the Rat Brain Both in Basal Condition and following Learning Predominantly Derives from the Maternal Allele.

    Directory of Open Access Journals (Sweden)

    Xiaojing Ye

    Full Text Available Insulin like growth factor 2 (Igf2 is known as a maternally imprinted gene involved in growth and development. Recently, Igf2 was found to also be regulated and required in the adult rat hippocampus for long-term memory formation, raising the question of its allelic regulation in adult brain regions following experience and in cognitive processes. We show that, in adult rats, Igf2 is abundantly expressed in brain regions involved in cognitive functions, like hippocampus and prefrontal cortex, compared to the peripheral tissues. In contrast to its maternal imprinting in peripheral tissues, Igf2 is mainly expressed from the maternal allele in these brain regions. The training-dependent increase in Igf2 expression derives proportionally from both parental alleles, and, hence, is mostly maternal. Thus, Igf2 parental expression in the adult rat brain does not follow the imprinting rules found in peripheral tissues, suggesting differential expression regulation and functions of imprinted genes in the brain.

    OBJECTIVE: To investigate the relationship between levels of insulin-like growth factors 1 and 2 (IGF-1, IGF-2) and insulin-like growth factor binding protein 3 (IGFBP-3) in antenatal maternal serum and gestational hypertension and pre-eclampsia (PET). METHODS: Prospective cohort study of 1650 low-risk Caucasian women in a University teaching hospital in London. Statistical analysis was performed using commercial software (SPSS for Windows, version 6.1, SPSS, Chicago, IL), with P < 0.05 as significant. Maternal IGF 1, IGF 2 and IGF BP-3 were assessed on maternal blood at booking. Blood pressure was checked at each visit in conjunction with urine analysis. The Davey & MacGillivray 1988 classification system was used in making the diagnosis of PET. RESULTS: There was no significant correlation between maternal IGF-1 or IGFBP-3 levels and gestational hypertension or PET. However, a significant positive correlation does exist between maternal IGF-2 levels and PET. CONCLUSIONS: Maternal IGF-2 has a significant positive correlation with PET.

    Possible mediators of the relation between maternal depressive symptomatology and parenting behavior were examined for 96 children with ADHD and their mothers drawn from the Multimodal Treatment Study of Children with ADHD (MTA) as part of an add-on investigation conducted by two of the six MTA sites. General cognitions (i.e., maternal locus of control and self-esteem) and parenting-specific factors (i.e., maternal parenting efficacy and parenting stress) were examined as possible mediators. Findings provide initial support that maternal parenting stress, as well as maternal locus of control and self-esteem mediate the relation between maternal depressive symptomatology and parenting behavior. This provides support for the argument that some families of children with ADHD may benefit from an expanded version of parent management training that includes sessions directly targeting affective and cognitive factors in parents, similar to treatment programs used to treat childhood conduct problems.

    To document the levels and the determinants of dichloro-dyphenyl-trichloroethane (DDT) metabolites in maternal milk, we conducted a cohort study of 50 adult females who lived in Mexico City. We measured social and dietary characteristics via interview. Levels of DDT metabolites were determined by gas-liquid chromatography. The mean values (lipid milk basis) were 0.162 ppm p,p'-DDT; 0.138 ppm o,p'-DDT; and 0.594 ppm 2,2(bis)p-chlorophyenyl-1-1-dichloroethylene (DDE). The main determinants of DDT metabolites were maternal age, lifetime lactation, history of living in an agricultural area, and consumption of salted meat and fish. We estimated that 6.0% of the breast-fed babies had daily intakes of DDT above the level of 0.005 mg/kg d recommended by the World Health Organization/Food and Agriculture Organization of the United Nations (WHO/FAO). Health-outcomes research among children is needed, and investigators should design or adjust current surveillance programs.

    2010-11-01

    In recent years Vietnam has experienced a high sex ratio at birth (SRB) amidst rapid socioeconomic and demographic changes. However, little is known about the differentials in SRB between maternal socioeconomic and demographic groups. The paper uses data from the annual Population Change Survey (PCS) in 2006 to examine the relationship of the sex ratio of the most recent birth with maternal socioeconomic and demographic characteristics and the number of previous female births. The SRB of Vietnam was significantly high at 111.4 (95% CI 109.7-113.1) for the period 1st April 2000 to 31st March 2006. Multivariate analysis reveals that sex of the most recent birth is strongly related with the number of previous female births. This association is consistent across different socioeconomic and demographic groups of women. Given the high SRB in Vietnam, further research into the reasons for high SRB in these groups is required, as are intervention programmes such as those raising the public awareness of its negative consequences.

    To analyze dietary patterns of infants and its association with maternal socioeconomic, cultural, and demographic variables. A cross-sectional study was conducted with two groups of mothers of children up to 24 months (n=202) living in the city of Maceió, Alagoas, Northeast Brazil. The case group consisted of mothers enrolled in a Family Health Unit. The comparison group consisted of mothers who took their children to two private pediatric offices of the city. Dietary intake was assessed using a qualitative and validated food frequency questionnaire (FFQ). The evaluation of the FFQ was performed by a method in which the overall rate of consumption frequency is converted into a score. Children of higher income families and mothers with better education level (control group) showed the highest median of consumption scores for fruits and vegetables (p<0.01) and meat, offal, and eggs (p<0.01), when compared with children of the case group. On the other hand, the median of consumption scores of manufactured goods was higher among children in the case group (p<0.01). Maternal socioeconomic status influenced the quality of food offered to the infant. In the case group, children up to 24 months already consumed industrial products instead of healthy foods on their menu. Copyright © 2015 Sociedade de Pediatria de São Paulo.

    There is a long-standing debate on the role of genetic factors influencing homosexuality because the presence of these factors contradicts the Darwinian prediction according to which natural selection should progressively eliminate the factors that reduce individual fecundity and fitness. Recently, however, Camperio Ciani, Corna, and Capiluppi (Proceedings of the Royal Society of London, Series B: Biological Sciences, 271, 2217-2221, 2004), comparing the family trees of homosexuals with heterosexuals, reported a significant increase in fecundity in the females related to the homosexual probands from the maternal line but not in those related from the paternal one. This suggested that genetic factors that are partly linked to the X-chromosome and that influence homosexual orientation in males are not selected against because they increase fecundity in female carriers, thus offering a solution to the Darwinian paradox and an explanation of why natural selection does not progressively eliminate homosexuals. Since then, new data have emerged suggesting not only an increase in maternal fecundity but also larger paternal family sizes for homosexuals. These results are partly conflicting and indicate the need for a replication on a wider sample with a larger geographic distribution. This study examined the family trees of 250 male probands, of which 152 were homosexuals. The results confirmed the study of Camperio Ciani et al. (2004). We observed a significant fecundity increase even in primiparous mothers, which was not evident in the previous study. No evidence of increased paternal fecundity was found; thus, our data confirmed a sexually antagonistic inheritance partly linked to the X-chromosome that promotes fecundity in females and a homosexual sexual orientation in males.

    We examined the risk of maternal obesity in 588 pregnant women weighing at least 113.6 kilograms (250 pounds) during pregnancy. Compared with a control group matched for age and parity, we found a significantly increased risk in the obese patient for gestational diabetes, hypertension, therapeutic induction, prolonged second stage of labor, oxytocin stimulation of labor, shoulder dystocia, infants weighing more than 4,000 grams and delivery after 42 weeks gestation. Certain operative complications were also more common in obese women undergoing cesarean section including estimated blood loss of more than 1,000 milliliters, operating time of more than two hours and wound infection postoperatively. These differences remained significant after controlling for appropriate confounding variables. We conclude that maternal obesity should be considered a high risk factor.

    Full Text Available Background: low birth weight is multifactorial and is commonly attributed to maternal, fetal and environmental causes. Dietary habits linked to inadequate maternal nutritional factors are decisive. Objective: to identify maternal nutritional factors related to low birth weight in patients of the consultation Area # I in Cienfuegos. Methods: an analytical, retrospective and case-control study was conducted from January 2006 to December 2008. We studied 50 mothers of low birth weight infants (cases and 100 mothers of normal weight children (controls at a rate of 2 per case. They were selected out of birth records in the health area. Obstetric medical records were reviewed and an interview was applied to each patient in order to assess their nutritional habits according to meals frequency and more widely consumed food groups. The data processing was performed using SPSS version 15,0. The results are presented in tables with absolute frequencies, percentages and results of the statistical techniques used. Results: maternal age, nutritional status in early pregnancy, weight gain during pregnancy and hemoglobin in the third quarter emerged as risk factors. Women with unstable and insufficient eating habits were 33 times more likely to have low birth weight infants and women who reported unhealthy diets according to more widely consumed food groups were estimated to be nine times more exposed to risk. Conclusions: maternal nutritional factors influenced the incidence of low birth weight, primarily in the cases of inadequate eating habits.Fundamento: el bajo peso al nacer es multifactorial y se atribuye a causas maternas, fetales y ambientales.

    Pathological outcomes, including metabolic and endocrine disturbances, of maternal deprivation (MD) in Wistar rats depend on gender and the timing of deprivation during development. We analyzed the effect of MD between postnatal days 9 and 10, a critical period in hypothalamic development, on circulating hormones and local production of trophic factors involved in this process, as well as on markers of cell turnover and maturation. Males and females were studied 12 and 24 h after MD and 12 h (MD36) after returning the dam to her pups. Circulating corticosterone levels were increased and glucose and leptin levels decreased throughout the study in both sexes. Hypothalamic mRNA levels of leptin receptor increased significantly at MD24 in both sexes, normalizing in females at MD36, but not in males. In male rats insulin-like growth factor mRNA levels were significantly decreased at MD24 and brain derived neurotrophic factor mRNA levels decreased at MD12 and MD24, with both trophic factors unaffected in females. In males cell proliferation was significantly decreased at MD36, as were the glial structural proteins, glial fibrillary acidic protein and vimentin. In females, nestin levels decreased significantly at MD24. These results indicate that MD differently affects trophic factors and cell-turnover in the hypothalamus of males and females, which may underlie the sex differences seen in the endocrine and metabolic outcome.

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    UV Spectrophotometric Target Factor Analysis (TFA) was used for the simultaneous determination of four components (acetaminophen, guuaifenesin, caffeine, Chlorphenamine maleate) in cough syrup. The computer program of TFA is based on VC++ language. The difficulty of overlapping of absorption spectra of four compounds was overcome by this procedure. The experimental results show that the average recovery of each component is all in the range from 98.9% to 106.8% and each component obtains satisfactory results without any pre-separation.

    effect of maternal, socioeconomic and obstetric variables, as well the presence of artery incisions in the 20th and 24th weeks on the fetal weight estimated at the end of pregnancy (36th week in pregnant women attended by Programa Saúde da Família, in an inland town of the northeast of Brazil. METHODS: a longitudinal study including 137 pregnant women, who have been followed up every four weeks in order to assess clinical, socioeconomic and obstetric conditions, including their weight. The uterine arteries were evaluated by Doppler in the 20th and 24th weeks, the fetal weight and the amniotic fluid index (AFI, determined in the 36th week. The initial maternal nutritional state has been determined by the body mass index (BMI, the pregnant women being classified as low weight, eutrophic, over weight and obese. Weight gain during gestation has been evaluated, according to the initial nutritional state, being classified at the end of the second and third trimester as insufficient, adequate and excessive weight gain. Analysis of variance was performed to evaluate the association of the fetal weight in the 36th week with the predictor variables, adjusted by multiple linear regression. RESULTS: an association between the fetal weight estimated in the 36th week and the mother's age (p=0.02, mother's job (p=0.02, initial nutritional state (p=0.04, weight gain in the second trimester (p=0.01, presence of incisions in the uterine arteries (p=0.02, and AFI (p=0.007 has been observed. The main factors associated to the fetal weight estimated in the 36th week, after the multiple regression analysis were: BMI at the pregnancy onset, weight gain in the second trimester, AFI and tabagism. CONCLUSIONS: in the present study, the fetal weight is positively associated with the initial maternal nutritional state, the weight gain in the second trimester and the volume of amniotic fluid, and negatively, to tabagism.

    Full Text Available Aims. To evaluate the prognostic significance of serum interleukin-6 (IL-6 in colorectal cancer (CRC. Patients and Methods. Preoperative serum IL-6 was measured in 233 CRC patients and 13 healthy controls. Relationships between IL-6 and various clinicopathological factors were evaluated, and the overall survival (OS and disease-free survival (DFS rates according to IL-6 status were calculated for all patients and according to disease stage. Results. The mean IL-6 level was 6.6 pg/mL in CRC patients and 2.6 pg/mL in healthy controls. Using a cutoff of 6.3 pg/mL, obtained using receiver operating characteristic curve analysis, 57 patients had a high IL-6 level. The mean value was higher for stage II disease than for stage III disease. IL-6 status correlated with C-reactive protein (CRP and carcinoembryonic antigen levels, obstruction, and pT4 disease. The OS differed according to the IL-6 status for all patients, whereas the DFS differed for all patients and for those with stage II disease. The Cox proportional hazards model showed that pT4 disease was an independent risk factor for recurrence in all CRC patients; IL-6, CRP, and pT4 were significant risk factors in stage II patients. Conclusions. The preoperative IL-6 level influences the risk of CRC recurrence.

  13. Current Changes in Pubertal Timing: Revised Vision in Relation with Environmental Factors Including Endocrine Disruptors.

    The aim of this chapter is to revise some common views on changes in pubertal timing. This revision is based on recent epidemiological findings on the clinical indicators of pubertal timing and data on environmental factor effects and underlying mechanisms. A current advancement in timing of female puberty is usually emphasized. It appears, however, that timing is also changing in males. Moreover, the changes are towards earliness for initial pubertal stages and towards lateness for final stages in both sexes. Such observations indicate the complexity of environmental influences on pubertal timing. The mechanisms of changes in pubertal timing may involve both the central neuroendocrine control and peripheral effects at tissues targeted by gonadal steroids. While sufficient energy availability is a clue to the mechanism of pubertal development, changes in the control of both energy balance and reproduction may vary under the influence of common determinants such as endocrine-disrupting chemicals (EDCs). These effects can take place right before puberty as well as much earlier, during fetal and neonatal life. Finally, environmental factors can interact with genetic factors in determining changes in pubertal timing. Therefore, the variance in pubertal timing is no longer to be considered under absolutely separate control by environmental and genetic determinants. Some recommendations are provided for evaluation of EDC impact in the management of pubertal disorders and for possible reduction of EDC exposure along the precautionary principle.

    To determine the factors which affect the perinatal deaths in early and late fetal growth restriction (FGR) fetuses using threshold of estimated fetal weight (EFW) fetuses, defined as an EFW fetuses considered as growth restrictions were confirmed by birth weight. Fetuses with multiple pregnancy, congenital malformation, chromosomal abnormality, and premature rupture of membrane were excluded. Samples were grouped in early and late FGR. Early FGR fetuses was classified as gestational age at birth ≤ 34 weeks and late FGR was classified as gestational age at birth > 34 weeks. Factors which affect the perinatal deaths were analyzed descriptively in early and late FGR. The perinatal mortality was calculated by adding the number of stillbirths and neonatal deaths. The study included 86 early and 185 late FGR fetuses, 31 resulted in perinatal deaths, 28 perinatal deaths were in early FGR, and three perinatal deaths were in late FGR. Perinatal deaths occurred more commonly in early FGR fetuses with an EFW death in early FGR. All three perinatal deaths in late FGR occurred in fetuses with EFW death was found significantly higher in increased vascular impedance of UtAs whatever the umbilical artery Doppler.

    Relativistic models for finite nuclei contain spurious center-of-mass motion in most applications for the nuclear many-body problem, where the nuclear wave function is taken as a single Slater determinant within a space-fixed frame description. We use the Peierls-Yoccoz projection method, previously developed for relativistic approaches together with a reparametrization of the coupling constants that fits binding energies and charge radius and apply our results to calculate elastic electron scattering monopole charge form factors for light nuclei.

    Full Text Available Problem statement. For planning and organization of urban construction is necessary to analyze the use of areas. Territorial resources of the city, being used for construction and other urban purposes, consists of plots of land: disposable, reserved and undeveloped in previous years of construction in progress; residential districts and blocks of obsolete housing fund; industrial and municipal and warehouse enterprises being used irrationally or stopped to work; the defence department, where the amortized warehouses and other main funds are that are not used by purpose; agricultural enterprises where the obsolete industrial funds, haying, nurseries, greenhouses. The number of free areas suitable for future urban development is extremely limited. However a considerable part of the territories of almost all functional zones is used inefficiently. Purpose. Formalization of a factor of investment attractiveness of territories for the further identification and research of the connection between it and the cost of housing construction is necessary. Conclusion. The identification of regularities of influence of the factor of investment attractiveness of territories on the cost of construction of high-rise buildings allow to obtain a quantitative estimate of this effect and can be used in the development of the methodology of substantiation of the expediency and effectiveness of the implementation of highrise construction projects, based on organizational and technological aspects.

    Full Text Available Introduction: A cleft lip with or without a cleft palate is one of the major congenital anomalies observed in newborns. This study explored the risk factors for oral clefts in Gorgan, Northern Iran.  Materials and Methods: This hospital-based case-control study was performed in three hospitals in Gorgan, Northern Iran between April 2006 and December 2009. The case group contained 33 newborns with oral clefts and the control group contained 63 healthy newborns. Clinical and demographic factors, including date of birth, gender of the newborns, type of oral cleft, consanguinity of the parents, parental ethnicity, and the mother's parity, age, education and intake of folic acid were recorded for analysis.  Results: A significant association was found between parity higher than 2 and the risk of an oral cleft (OR= 3.33, CI 95% [1.20, 9.19], P> 0.02. According to ethnicity, the odds ratio for oral clefts was 0.87 in Turkmens compared with Sistani people (CI 95% [0.25, 2.96] and 1.11 in native Fars people compared with Sistani people (CI 95% [0.38, 3.20]. A lack of folic acid consumption was associated with an increased risk of oral clefts but this was not statistically significant (OR = 1.42, CI 95% [0.58, 3.49]. There were no significant associations between sex (OR boy/girl = 0.96, CI 95% [0.41, 2.23], parent familial relations (OR = 1.07, CI 95% [0.43, 2.63], mother's age and oral clefts.  Conclusions:  The results of this study indicate that higher parity is significantly associated with an increased risk of an oral cleft, while Fars ethnicity and a low intake of folic acid increased the incidence of oral clefts but not significantly.

    Full Text Available Health inequalities: differences in health status or in the distribution of health determinants between different population groups. Some health inequalities are attributable to biological variations or free choice and others are attributable to the external environment and conditions mainly outside the control of the individuals concerned. 347 million people worldwide have diabetes. In 2012 an estimated 1.5 million deaths were directly caused by diabetes. More than 80% of diabetes deaths occur in low- and middle-income countries. WHO projects that diabetes will be the 7th leading cause of death in 2030. Healthy diet, regular physical activity and maintaining a normal body weight can prevent or delay the onset of type 2 diabetes. Risk factors: 1. Age- the prevalence of diabetes rises steeply with age: *one in twenty people over the age of 65 have diabetes, *and this rises to one in five people over the age of 85 years. The diagnosis of diabetes may be delayed in older people, with symptoms of diabetes being wrongly attributed to ageing. 2. Ethnic: type 2 diabetes is up to six times more common in people of South Asian descent and up to three times more common in those of African and African-Caribbean descent then in the white population. It is also more common in people of Chinese descent and other non-Caucasian groups. 3. Gender: the frequency of diabetes usually is higher in men than in women. This may be because gender compounds other aspects of inequality- women often bear the brunt of poverty, and socio-economic differences in the prevalence of diabetes are more marked for women, probably because of differences in smoking rates, food choices and the prevalence of obesity. 4. Overweight/Obesity: every 1 kg/m2 more causes increase risk: cardiovascular diseases 2%, coronary artery disease- 3% , myocardial infarction- 5% , heart failure- 5% , peripheral vascular disease- 5%.

    Sheep and goats rapidly establish an exclusive relationship with their neonate following contact with it during a sensitive period of maternal responsiveness induced by the physiological events occurring at parturition. The data concerning the sensory, physiological, and neurobiological factors involved in the activation of both maternal responsiveness and the establishment of selective nursing indicates that these processes are activated simultaneously by the combined action of two main factors, the prepartum rise in circulating estrogen and the vaginocervical stimulation (VCS) caused by fetus expulsion. On the one hand, these two factors act on a neural network including the main olfactory system (MOB), the medial preoptic area (MPOA), and the paraventricular nucleus of the hypothalamus (PVN) to induce maternal responsiveness towards any neonate. The intracerebral release of oxytocin (OT) from the PVN, and the triggering of olfactory attraction for amniotic fluid (AF) are key elements in this process. On the other hand, VCS at birth also sets the MOB ready to memorize the individual odor of the neonate, through the release of peptides and neurotransmitters (noradrenaline and acetylcholine). In addition to the MOB, the network involved in recognition mainly includes the medial and cortical amygdala. Across consolidation processes, reorganization occurs in the network engaged in lamb recognition. Whether this memorization may be potentiated by other sensory cues is not known. The identification of the chemosensory compounds involved in the attraction for AF and in the recognition of the neonate is important for understanding the mechanisms of maternal attachment.

    2015-01-01

    Researchers in Nigeria examined the epidemiological characteristics and factors associated with maternal outcomes using a mixed method approach: a prospective case control study design involving 375 pregnant women who received maternal care from a tertiary facility and in-depth interviews reporting the experience of near-miss survivors. A generalized ordered logit model was used to generate the estimates of partial proportional odds ratios (and 95% confidence intervals) across categories of the outcome variable. Factors strongly associated with maternal morbidity were late referral of women, presence of complications at booking antenatal visits, low birth weight, and severe birth asphyxia. The nearmiss women were further characterized, and a low proportion (25%) had organ dysfunction or failure. The challenge of such diagnoses in resource-constrained settings raises questions about the appropriateness of using organ dysfunction criteria in developing countries.

    Maternal feeding styles in infancy and early childhood are associated with children's later risk for overweight and obesity. Maternal psychosocial factors that influence feeding styles during the complementary feeding period, the time during which infants transition from a milk-based diet to one that includes solid foods and other non-milk products, have received less attention. The present study explores how maternal psychosocial factors-specifically self-esteem, parenting self-efficacy, parenting satisfaction, and depression symptoms-influence mothers' infant feeding styles at nine months of age, a time during which solid foods eating habits are being established. Participants included 160 low-income, African-American mother-infant pairs in central North Carolina who were enrolled in the Infant Care and Risk of Obesity Study. Regression models tested for associations between maternal psychosocial characteristics and pressuring and restrictive feeding styles. Models were first adjusted for maternal age, education, marital status and obesity status. To account for infant characteristics, models were then adjusted for infant weight-for-length, distress to limitations and activity level scores. Maternal self-esteem was negatively associated with pressuring to soothe. Maternal parenting self-efficacy was positively associated with restriction-diet quality. Maternal parenting satisfaction and depression symptoms were not associated with feeding styles in the final models. Focusing on strengthening maternal self-esteem and parenting self-efficacy may help to prevent the development of less desirable infant feeding styles. Copyright © 2016 Elsevier Ltd.

    Obesity impairs reproductive functions through multiple mechanisms, possibly through disruption of ovarian function. We hypothesized that increased adiposity will lead to a proinflammatory gene signature and upregulation of Egr-1 protein in ovaries from obese (OB; n = 7) compared with lean (LN; n = 10) female Sprague-Dawley rats during the peri-implantation period at 4.5 days postcoitus (dpc). Obesity was induced by overfeeding (40% excess calories for 28 days) via total enteral nutrition prior to mating. OB dams had higher body weight (P ovaries from LN vs. OB dams (±1.3 fold, P ovaries from OB compared with LN (P ovaries. Moreover, Egr-1 was localized to granulosa cells, with the highest expression in cumulus cells of preovulatory follicles. mRNA expression of VCAN, AURKB, and PLAT (P obesity. In summary, maternal obesity led to an upregulation of inflammatory genes and Egr-1 expression in peri-implantation ovarian tissue and a concurrent downregulation of GLUTs and Akt and PI3K protein levels.

    Full Text Available Background and Objective: Nigeria has one of the highest maternal and child death rates in the world. Postnatal care is one of the major interventions recommended to reduce maternal and newborn deaths globally. The aim of this study is to determine the utilization of postnatal health services and identify the factors which affect this utilization among mothers of under-fives in Lagos. Methods: This was a cross-sectional study among women of child bearing age in Lagos using structured, interviewer-administered questionnaire. Six hundred women selected by multi stage sampling method were interviewed and data analyzed with EPI-info Version 3.5.1. Results: Two thirds (66.2% of the respondents utilized postnatal health services. Factors which significantly influenced postnatal health services utilization were: number of children (p=0.031, maternal education (p=0.001, religion (Fisher′s exact p= 0.004, number of antenatal care visits (p<0.001 and skilled attendance at birth (p<0.001. Maternal occupation and time taken to the health facility were not significant determinants of utilization. Conclusion: Utilization of postnatal care services was high but not optimal. Interventions to increase family planning use and improve maternal educational status should be undertaken as well as increasing use of focused antenatal care and skilled delivery services.

    High rate of maternal death is one of the major public health concerns in Tanzania. Most of maternal deaths are caused by factors attributed to pregnancy, childbirth and poor quality of health services. More than 80% of maternal deaths can be prevented if pregnant women access essential maternity care and assured of skilled attendance at childbirth as well as emergency obstetric care. The objective of this review was to analyse maternal mortality situation in Tanzania during the past 50 years and to identify efforts, challenges and opportunities of reducing it. This paper was written through desk review of key policy documents, technical reports, publications and available internet-based literature. From 1961 to 1990 maternal mortality ratio in Tanzania had been on a downward trend from 453 to 200 per 100,000 live births. However, from 1990's there been an increasing trend to 578 per 100,000 live births. Current statistics indicate that maternal mortality ratio has dropped slightly in 2010 to 454 per 100,000 live births. Despite a high coverage (96%) in pregnant women who attend at least one antenatal clinic, only half of the women (51%) have access to skilled delivery. Coverage of emergence obstetric services is 64.5% and utilization of modern family planning method is 27%. Only about 13% of home deliveries access post natal check-up. Despite a number of efforts maternal mortality is still unacceptably high. Some of the efforts done to reduce maternal mortality in Tanzania included the following initiatives: reproductive and child survival; increased skilled delivery; maternal death audit; coordination and integration of different programs including maternal and child health services, family planning, malaria interventions, expanded program on immunization and adolescent health and nutrition programmes. These initiatives are however challenged by inadequate access to maternal health care services. In order to considerably reduce maternal deaths some of recommended

    Receiving an education is essential for children living in poverty to fulfil their potential. Success in the early years of schooling is important as children who repeat grade one are particularly at risk for future dropout. We examined early life factors associated with grade repetition through logistic regression and explored reasons for repeating a grade through parent report. In 2012-2014 we re-enrolled children aged 7-11 years in rural KwaZulu-Natal who had been part of an early life intervention. Of the 894 children included, 43.1% had repeated a grade, of which 62.9% were boys. Higher maternal education (aOR 0.44; 95% CI 0.2-0.9) and being further along in the birth order (aOR 0.46; 95% CI 0.3-0.9) reduced the odds of grade repetition. In addition, maternal HIV status had the strongest effect on grade repetition for girls (aOR 2.17; 95% CI 1.3-3.8), whereas for boys, it was a fridge in the household (aOR 0.59; 95% CI 0.4-1.0). Issues with school readiness was the most common reason for repeating a grade according to parental report (126/385, 32.7%), while school disruptions was an important reason among HIV-exposed boys. Further research is needed to elucidate the pathways through which HIV affects girls' educational outcomes and potentially impacts on disrupted schooling for boys. Our results also highlight the importance of preparation for schooling in the early years of life; future research could focus on gaining a better understanding of mechanisms by which to improve early school success, including increased quality of reception year and investigating the protective effect of older siblings.

    Insulin-like growth factors (IGFs) are well-known regulators of embryonic growth and differentiation. IGF function is closely related to insulin action. IGFs are available to the preimplantation embryo through maternal blood (endocrine action), uterine secretions (paracrine action) and by the embryo itself (autocrine action). In rabbit blastocysts, embryonic IGF1 and IGF2 are specifically strong in the embryoblast (ICM). Signalling of IGFs and insulin in blastocysts follows the classical pathway with Erk1/2 and Akt kinase activation. The aim of this study was to analyse signalling of IGFs in experimental insulin dependent diabetes (exp IDD) in pregnancy, employing a diabetic rabbit model with uterine hypoinsulinemia and hyperglycaemia. Exp IDD was induced in female rabbits by alloxan treatment prior to mating. At 6 days p.c., the maternal and embryonic IGFs were quantified by RT-PCR and ELISA. In pregnant females, hepatic IGF1 expression and IGF1 serum levels were decreased while IGF1 and IGF2 were increased in endometrium. In blastocysts, IGF1 RNA and protein was approx. 7.5-fold and 2-fold higher, respectively, than in controls from normoglycemic females. In cultured control blastocysts supplemented with IGF1 or insulin in vitro for 1 or 12 h, IGF1 and insulin receptors as well as IGF1 and IGF2 were downregulated. In cultured T1D blastocysts activation of Akt and Erk1/2 was impaired with lower amounts of total Akt and Erk1/2 protein and a reduced phosphorylation capacity after IGF1 supplementation. Our data show that the IGF axis is severely altered in embryo-maternal interactions in exp IDD pregnancy. Both, the endometrium and the blastocyst produce more IGF1 and IGF2. The increased endogenous IGF1 and IGF2 expression by the blastocyst compensates for the loss of systemic insulin and IGF. However, this counterbalance does not fill the gap of the reduced insulin/IGF sensitivity, leading to a developmental delay of blastocysts in exp IDD pregnancy.

    Findings from comparisons of joint and sole custody families that do not control for predivorce differences in demographic and family process variables (factors that may predispose families to choose or be awarded joint custody) are of limited generalizability, since obtained group differences may be attributable to predisposing (self-selection) factors, custody, or both. This study compared a random sample of 254 recently separated, not-yet-divorced families on 71 predivorce variables that might plausibly differentiate between families awarded joint legal versus sole maternal custody. Twenty such factors were identified and controlled for in subsequent comparisons of 52 sole maternal and 26 joint legal custody families 2 years postdivorce. Families with joint custody had more frequent father-child visitation, lower maternal satisfaction with custody arrangements, more rapid maternal repartnering, and fewer child adjustment problems (net of predivorce selection factors). Moreover, these effects did not appear to be moderated by level of predecree parental conflict. No association between custody and fathers' compliance with child support orders was obtained.

    Introduction An imbalance between angiogenic and anti-angiogenic factors has been proposed as central to the pathophysiology of preeclampsia (PE). Indeed, patients with PE and those delivering small-for-gestational age (SGA) neonates have higher plasma concentrations of soluble vascular endothelial growth factor receptor-1 (sVEGFR-1) and the soluble form of endoglin (s-Eng), as well as lower plasma concentrations of vascual endothelial growth factor (VEGF) and placental growth factor (PlGF) than do patients with normal pregnancies. Of note, this imbalance has been observed before the clinical presentation of PE or the delivery of an SGA neonate. The objective of this study was to determine if changes in the profile of angiogenic and anti-angiogenic factors in maternal plasma between the first and second trimesters are associated with a high risk for the subsequent development of preeclampsia and/or delivery of an SGA neonate. Methods This longitudinal case-control study included 402 singleton pregnancies in the following groups: 1) normal pregnancies with appropiate for gestational age (AGA) neonates (n=201); 2) patients who delivered an SGA neonate (n=145); and 3) patients who developed PE (n=56). Maternal plasma samples were obtained at the time of each prenatal visit, scheduled at 4-week intervals from the first or early second trimester until delivery. In this study, we included two samples per patient: 1) first sample obtained between 6 and 15 weeks of gestation (“first trimester” sample); and 2) second sample obtained between 20 and 25 weeks of gestation (“second trimester” sample). Plasma concentrations of s-Eng, sVEGFR-1 and PlGF were determined by specific and sensitive immunoassays. Changes in the maternal plasma concentrations of these angiogenesis-related factors were compared among normal patients and those destined to develop PE or deliver an SGA neonate while adjusting for maternal age, nulliparity and body mass index (BMI).

    Full Text Available Global Program to Eliminate Lymphatic Filariasis (GPELF launched by WHO aims to eliminate the disease by 2020. To achieve the goal annual mass drug administration (MDA with diethylcarbamazine (DEC plus albendazole (ABZ has been introduced in all endemic countries. The current policy however excludes pregnant mothers and children below two years of age from MDA. Since pregnancy and early childhood are critical periods in determining the disease outcome in older age, the present study was undertaken to find out the influence of maternal filarial infection at the time of pregnancy on the susceptibility outcome of children born in a community after implementation of MDA for the first time.The participants in this cohort consists of pregnant mothers and their subsequently born children living in eight adjacent villages endemic for filarial infections, in Khurda District, Odisha, India, where MDA has reduced microfilariae (Mf rate from 12% to 0.34%. Infection status of mother and their children were assessed by detection of Mf as well as circulating filarial antigen (CFA assay. The present study reveals a high rate of acquiring filarial infection by the children born to infected mother than uninfected mothers even though Mf rate has come down to < 1% after implementation of ten rounds of MDA.To attain the target of eliminating lymphatic filariasis the current MDA programme should give emphasis on covering the women of child bearing age. Our study recommends incorporating supervised MDA to Adolescent Reproductive and Sexual Health Programme (ARSH to make the adolescent girls free from infection by the time of pregnancy so as to achieve the goal.

    The actions that have followed the recommendations of successive publications of the UK Confidential Enquiries into Maternal Deaths have helped save mothers' lives and reduced ill health and morbidity. Through the implementation of their recommendations, they have helped improve access to, and the quality of, the maternity care provided for all pregnant women in the United Kingdom. The enquires help review, assess, and identify the underlying remediable factors that contributed to mothers' deaths and aggregate the lessons learned to make recommendations to develop services that help overcome many of the barriers to safe, high-quality maternity care, which vulnerable women continue to face. This chapter provides a short summary of the positive contributions the successive reports on Confidential Enquiries into Maternal Deaths, "Saving Mothers' Lives," have made to maternal health outcomes in the United Kingdom for more than half a century. It also demonstrates why such systems continue to be beneficial around the world, including countries with very low maternal mortality rates.

    To determine correlations between macrophage colony-stimulating factor (MCSF) levels in maternal blood during first trimester screening with respect to normal and pathological pregnancies. This was a prospective single centre study. First trimester screening was performed according to FMF London certificates. Nuchal translucency, PAPP-A and free β-HCG were obtained as well as M-CSF serum levels in maternal blood. Fetal karyotyping was achieved by chorionic villi sampling. 125 patients were enrolled in this study. 21 pregnancies had confirmed aberrant karyotypes. Trisomy 21 cases showed significantly elevated M-CSF levels of 270 ± 91 pg/ml (p = 0.032), whereas cases of trisomy 13 (183 ± 68 pg/ml) and trisomy 18 (143 ± 40 pg/ml) had low M-CSF levels. Furthermore M-CSF levels tended to be low in preterm deliveries, placental insufficiency and nicotine consumption. In cases with gestational diabetes M-CSF tended to be elevated. Furthermore we found a positive correlation between high free β-human chorionic gonadotropin (hcg) and MCSF values. There was no correlation between pregnancy associated plasma protein (PAPP-A) and M-CSF. M-CSF is a cytokine promoting placental growth and differentiation. M-CSF is known to be involved in the process of implantation in pregnancy. The role of M-CSF with respect to disturbed pregnancy outcomes such as placental insufficiency in normal or aberrant karyotypes, for example, is yet subject to further research.

    Full Text Available Abstract Background There has been an increasing availability and accessibility of modern health services in rural Bangladesh over the past decades. However, previous studies on the socioeconomic differentials in the utilization of these services were based on a limited number of factors, focusing either on preventive or on curative modern health services. These studies failed to collect data from remote rural areas of the different regions to examine the socioeconomic differentials in health-seeking behavior. Methods Data from 3,498 randomly selected currently married women from three strata of households within 128 purposively chosen remote villages in three divisions of Bangladesh were collected in 2006. This study used bivariate and multivariate logistic analyses to examine both curative and preventive health-seeking behaviors in seven areas of maternal and child health care: antenatal care, postnatal care, child delivery care, mother's receipt of Vitamin A postpartum, newborn baby care, care during recent child fever/cough episodes, and maternal coverageby tetanus toxoid (TT. Results A principal finding was that a household's relative poverty status, as reflected by wealth quintiles, was a major determinant in health-seeking behavior. Mothers in the highest wealth quintile were significantly more likely to use modern trained providers for antenatal care, birth attendance, post natal care and child health care than those in the poorest quintile (χ2, p Conclusion Within rural areas of Bangladesh, where overall poverty is greater and access to health care more difficult, wealth differentials in utilization remain pronounced. Those programs with high international visibility and dedicated funding (e.g., Immunization and Vitamin A delivery have higher overall prevalence and a more equitable distribution of beneficiaries than the use of modern trained providers for basic essential health care services. Implications of these findings and

    birth weight is vital to the development potential of the newborn. Abnormal birth weight (such as low birth weight and macrosomia) is an important determinant of child survival, disabilities, stunting, and long-term adverse consequences for the onset of non-communicable diseases in the life course and therefore demands appropriate public health interventions. Stillbirths are also considered one of the most important, but most poorly understood and documented adverse outcomes of pregnancy. Therefore, this study aimed to assess the prevalence of abnormal birth weight and related maternal risk factors, as well as pregnancy outcomes, such as stillbirth. a retrospective study design was used to analyze 4262 delivery records for singleton pregnancies from January 2013 to December 2014 seen at the Hohoe municipal hospital, Volta region in Ghana. The data on birth weight and related factors were derived from the delivery book. Data was analyzed using STATA. Multinomial logistic regression was used to assess the association between maternal factors such as parity, age and intermittent preventive treatment of malaria, sex of infant and abnormal birth weight. Association between stillbirth and related factors was assessed using logistic regression. prevalence of low birth weight (risk of a first born being of low birth weight than second or third born (RR; 2.04, CI; 1.59-2.64, prisks of mothers low-birthweight infants (RR; 1.46, CI; 1.11-1.93, p=0.007) compared to mothers who were within the age ranges of 20-30 years and also among those who took only one (RR; 1.57, CI; 1.02-2.39, p=0.039) or no intermittent preventive treatment for malaria during pregnancy (RR; 1.57, CI; 1.24-1.98, p=Risk of macrosomic birth was particularly high among 5th born (RR; 2.66, CI; 1.43-4.95, p=0.002) compared to first or second born.

Acute-phase proteins and cytokines were measured by ELISA in 24 healthy pregnant women undergoing vaginal delivery or Cesarean section. Cord blood samples in addition to maternal blood were collected. SAA and CRP reached the maximum maternal serum levels 24 hours after delivery, while cytokines remained constant over time. SAA and CRP were significantly higher in maternal serum than in newborn's (P<.001 at the moment of delivery. SAA and CRP, regardless of the type of delivery, reproduce the common pattern observed in most inflammatory conditions. Proinflammatory cytokine serum levels do not mirror the increase in SAA and CRP levels.

    BACKGROUND: Cryptorchidism (undescended testis) is a common anomaly with largely unexplained etiology. Animal studies have suggested maternal emotional stress as a potential risk factor, but this has not been studied in humans. We aimed to investigate whether maternal bereavement due to the death...... of a close relative in the antenatal period increases the occurrence of cryptorchidism in the offspring. METHODS: In a population-based cohort, we studied death of a close relative as the exposure and cryptorchidism entries in nationwide medical registries as the outcome. Danish national registries included...... interval = 0.92-1.14]). Results were similar when the diagnosis was verified with surgery. We adjusted for maternal and paternal age, birth year, and family history of cryptorchidism. CONCLUSION: We observed no association between maternal bereavement before and during pregnancy and the occurrence...

    Full Text Available Abstract Background Over the last five years, international development organizations began to modify and adapt the conventional Performance Improvement Model for use in low-resource settings. This model outlines the five key factors believed to influence performance outcomes: job expectations, performance feedback, environment and tools, motivation and incentives, and knowledge and skills. Each of these factors should be supplied by the organization in which the provider works, and thus, organizational support is considered as an overarching element for analysis. Little research, domestically or internationally, has been conducted on the actual effects of each of the factors on performance outcomes and most PI practitioners assume that all the factors are needed in order for performance to improve. This study presents a unique exploration of how the factors, individually as well as in combination, affect the performance of primary reproductive health providers (nurse-midwives in two regions of Armenia. Methods Two hundred and eighty-five nurses and midwives were observed conducting real or simulated antenatal and postpartum/neonatal care services and interviewed about the presence or absence of the performance factors within their work environment. Results were analyzed to compare average performance with the existence or absence of the factors; then, multiple regression analysis was conducted with the merged datasets to obtain the best models of "predictors" of performance within each clinical service. Results Baseline results revealed that performance was sub-standard in several areas and several performance factors were deficient or nonexistent. The multivariate analysis showed that (a training in the use of the clinic tools; and (b receiving recognition from the employer or the client/community, are factors strongly associated with performance, followed by (c receiving performance feedback in postpartum care.

    Maternal feeding styles in infancy and early childhood are associated with children’s later risk for overweight and obesity. Maternal psychosocial factors that influence feeding styles during the complementary feeding period, the time during which infants transition from a milk-based diet to one that includes solid foods and other non-milk products, have received less attention. The present study explores how maternal psychosocial factors—specifically self-esteem, parenting self-efficacy, parenting satisfaction, and depression symptoms—influence mothers’ infant feeding styles at nine months of age, a time during which solid foods eating habits are being established. Participants included 160 low-income, African-American mother-infant pairs in central North Carolina who were enrolled in the Infant Care and Risk of Obesity Study. Regression models tested for associations between maternal psychosocial characteristics and pressuring and restrictive feeding styles. Models were first adjusted for maternal age, education, marital status and obesity status. To account for infant characteristics, models were then adjusted for infant weight-for-length, distress to limitations and activity level scores. Maternal self-esteem was negatively associated with pressuring to soothe. Maternal parenting self-efficacy was positively associated with restriction-diet quality. Maternal parenting satisfaction and depression symptoms were not associated with feeding styles in the final models. Focusing on strengthening maternal self-esteem and parenting self-efficacy may help to prevent the development of less desirable infant feeding styles. PMID:27174251

    To determine the frequency and risk factors of small-for-gestational-age newborns in a high-risk maternity. This is an observational, cross-sectional, and case-control study, conducted in a public tertiary care maternity hospital. Data from 998 newborns and their mothers were collected through interviews and review of medical records and prenatal care cards. Some placentas underwent histopathological analysis. The variables of small-for-gestational-age and non-small-for-gestational-age newborns and of their mothers were statistically compared by means of Student's t test, Fisher's exact test, and odds ratio. The significance level used was 0.050. There was a 17.9% frequency of small-for-gestational-age newborns. The statistically significant factors associated with the birth of these babies were female sex (p=0.012); positive history of another small-for-gestational-age child (p=0.006); inadequate prenatal care (p=0.019); smoking (p=0.003); hypertensive disorders of pregnancy (p=0.007); placental bleeding (p=0.009) and infarction (p=0.001). In the population studied, the frequency of small-for-gestational-age newborns was high and associated with sex, inappropriate prenatal care, presence of maternal diseases and addictions, and placental abnormalities.

    Full Text Available Slow progress has been made in achieving the Millennium Development Goals 4 and 5 in Ghana. Ensuring continuum of care (at least four antenatal visits; skilled birth attendance; postnatal care within 48 hours, at two weeks, and six weeks for mother and newborn is crucial in helping Ghana achieve these goals and beyond. This study examined the levels and factors associated with continuum of care (CoC completion among Ghanaian women aged 15-49.A retrospective cross-sectional survey was conducted among women who experienced live births between January 2011 and April 2013 in three regions of Ghana. In a two-stage random sampling method, 1,500 women with infants were selected and interviewed about maternal and newborn service usage in line with CoC. Multiple logistic regression models were used to assess factors associated with CoC completion.Only 8.0% had CoC completion; the greatest gap and contributor to the low CoC was detected between delivery and postnatal care within 48 hours postpartum. About 95% of women had a minimum of four antenatal visits and postnatal care at six weeks postpartum. A total of 75% had skilled assisted delivery and 25% received postnatal care within 48 hours. Factors associated with CoC completion at 95% CI were geographical location (OR = 0.35, CI 0.13-0.39, marital status (OR = 0.45; CI 0.22-0.95, education (OR = 2.71; CI 1.11-6.57, transportation (OR = 1.97; CI 1.07-3.62, and beliefs about childhood illnesses (OR = 0.34; CI0.21-0.61.The continuum of care completion rate is low in the study site. Efforts should focus on increasing postnatal care within 48 hours and overcoming the known obstacles to increasing the continuum of care completion rate.

    This review aimed at understanding pregnancy-induced changes in the maternal immune response and mechanisms for the establishment of feto-maternal tolerance. Articles cited in this review were obtained from PubMed in English from 2000 to 2014, and the search string included keywords such as feto-maternal tolerance, dendritic cells, macrophage, T regulatory cells, natural killer cells, cytokines and hormone. Articles regarding altered maternal immune response, including the proliferation and differentiation of the altered cells, and the production of cytokines and regulation of hormones in the feto-maternal interface were retrieved, reviewed and analyzed. The changes in immune cells and cytokines in the local uterine microenvironment and peripheral blood are correlated with the establishment of feto-maternal tolerance. The endocrine system regulates the maternal immune system, promoting modifications during pregnancy. In these regulatory networks, every factor is indispensible for others. The integration and balance of these immune factors during pregnancy give rise to an environment that enables the fetus to escape rejection by the maternal immune system. This progress is complicated, and needs more comprehensive exploration and explanation.

    Poor care-seeking behaviour of families may be responsible for the high prevalence of complications of newborn jaundice in the developing world. To examine the influence of family socio-demographic characteristics and maternal obstetric factors on health care-seeking behaviours for newborn jaundice and the inter-relationship between this behavior and severity of newborn jaundice. Mothers whose babies were referred to a Nigerian tertiary hospital with jaundice were studied in a cross-sectional survey for appropriate health-care seeking behaviours as well as the need for exchange transfusion and the occurrence of kernicterus in their babies. Out of 182 mother-baby pairs, 127 (69.8%) mothers recognized jaundice in their infants, 34.1% delayed care for ≥48 h, 40.6% sought medical care in orthodox health facilities while 20.9% did not seek care outside the home. In all, 61.5% mothers administered various medications to jaundiced babies. Appropriate health care-seeking behaviours were recorded among 28.6% mothers. Low maternal education had a significant relationship with delayed health care-seeking and the use of home remedies for newborn jaundice. A significantly higher proportion of babies who had home remedies had delayed care. Delayed care for ≥48 h was also significantly associated with high Total Serum Bilirubin on admission, higher requirement for exchange transfusion and higher occurrence of kernicterus. Intensive health education of families may help improve their health care-seeking behaviours for neonatal jaundice.

    Dietary habits established in early childhood contribute to lifelong dietary pattern and the development of early risk factors for disease in adulthood. Although a large body of epidemiologic data from Western countries show that the dietary pattern of children is influenced by maternal socio-economic and lifestyle characteristics, information on this topic in non-Western countries is absolutely lacking. The present study identified dietary patterns among infants aged 16-24 months, and then examined the influence of maternal socio-economic and lifestyle characteristics on identified dietary patterns. Subjects were 758 Japanese mother-child pairs. Dietary data of infants were collected from the mothers using a questionnaire. Dietary patterns were extracted from the consumption of 15 foods (times week(-1)) by cluster analysis. The following two dietary patterns were identified: 'fruits, vegetables and high-protein foods' (n = 483) and 'confectionaries and sweetened beverages' (n = 275) patterns. After adjustment for all other predictors, maternal educational level, number of infants' siblings and maternal dietary patterns were independently associated with dietary patterns of infants. Infants whose mothers had a higher educational level and the 'rice, fish and vegetables' dietary pattern were less likely to belong to the 'confectionaries and sweetened beverages' pattern, whereas infants whose mothers had a higher number of children and the 'wheat product' dietary pattern were more likely to belong to the 'confectionaries and sweetened beverages' than the 'fruits, vegetables and high-protein foods' pattern. In conclusion, the mother's socio-economic position and dietary patterns were associated with the dietary patterns of infants in the Japanese pairs as observed in the Western populations.

    Full Text Available Background. Modifiable factors in adulthood that explain the racial disparity in prostate cancer have not been identified. Because racial differences in utero that may account for this disparity are understudied, we investigated the association of maternal and neonate factors with cord blood telomere length, as a cumulative marker of cell proliferation and oxidative damage, by race. Further, we evaluated whether cord blood telomere length differs by race. Methods. We measured venous umbilical cord blood leukocyte relative telomere length by qPCR in 38 black and 38 white full-term male neonates. Using linear regression, we estimated geometric mean relative telomere length and tested for differences by race. Results. Black mothers were younger and had higher parity and black neonates had lower birth and placental weights. These factors were not associated with relative telomere length, even after adjusting for or stratifying by race. Relative telomere length in black (2.72 and white (2.73 neonates did not differ, even after adjusting for maternal or neonate factors (all p>0.9. Conclusions. Maternal and neonate factors were not associated with cord blood telomere length, and telomere length did not differ by race. These findings suggest that telomere length at birth does not explain the prostate cancer racial disparity.

    Continuity of breastfeeding is infrequent and indeterminate. Evidence is lacking regarding factors associated with breastfeeding at different postpartum time points. This prospective study investigated the change in, and correlates of, breastfeeding practices after delivery at a hospital and at 1, 3, and 6 months postpartum among first-time mothers. We followed a cohort of 300 primiparous mothers of Taiwan who gave birth at two hospitals during 2010-2011. Logistic and Cox regression analyses were performed to determine factors that were correlated with breastfeeding practices. In the study sample, the rate of exclusive breastfeeding during the hospital stay was 66%; it declined to 37.5% at 1 month and 30.2% at 3 months postpartum. Only 17.1% of women reported continuing breastfeeding at 6 months. Early initiation of breastfeeding, rooming-in practice, and self-efficacy were significantly related to exclusive breastfeeding during the hospital stay. After discharge, health literacy, knowledge, intention, and self-efficacy were positively and significantly associated with breastfeeding exclusivity. Later initiation (hazard ratio=1.53; 95% confidence interval, 1.05, 1.97), shorter intention (hazard ratio=1.42; 95% confidence interval, 1.13, 1.68), and self-efficacy (hazard ratio=0.98; 95% confidence interval, 0.96, 0.99) were important predictors of breastfeeding cessation within 6 months of delivery. Continuous breastfeeding practice for 6 months is challenging and difficult for new mothers. Results showed that factors related to breastfeeding varied over time after delivery. Interventions seeking to sustain breastfeeding should consider new mothers' needs and barriers at different times.

  16. Sexuality and maternity as additional factors of discrimination (and violence in women with disabilities

    2016-12-01

    Full Text Available Two of the numerous variables that affect women with disabilities, exposing them to processes intersectional discrimination, are associated with the still prevailing traditional patriarchal society models: sexuality and motherhood. Sometimes these factors are so severe that violate the fundamental rights of the persons in this social group, threatening their status as full citizens and contributing occasionally to their social exclusion. In this paper we present some of the findings related to these aspects, from an empirical study that analyzed the existing violence against women with disabilities, in order to visualize the specific vulnerability of the members of this social group.

    Conclusions: Anaemia in pregnancy is associated with several social and demographic factors. Strategies must be taken from the conceptional level itself by providing proper antenatal counseling and women should be economically empowered and good antenatal care must be made available and accessible to all of them. Even with routine iron prophylaxis in pregnancy, still the prevalence of anaemia is high, so should we consider one or two doses of routine parenteral iron therapy for all pregnant women?

    Full Text Available Exploration of dietary pattern associations within a multi-ethnic society context has been limited. We aimed to describe dietary patterns of 5664 pregnant women from the Growing Up in New Zealand study, and investigate associations between these patterns and maternal socio-demographic, place of birth, health and lifestyle factors. Participants completed a food frequency questionnaire prior to the birth of their child. Principal components analysis was used to extract dietary patterns and multivariable analyses used to determine associations. Four dietary components were extracted. Higher scores on, ‘Junk’ and ‘Traditional/White bread’, were associated with decreasing age, lower educational levels, being of Pacific or Māori ethnicity and smoking. Higher scores on, ‘Health conscious’ and ‘Fusion/Protein’, were associated with increasing age, better self-rated health, lower pre-pregnancy body mass index (BMI and not smoking. Higher scores on ‘Junk’ and ‘Health conscious’ were associated with being born in New Zealand (NZ, whereas higher scores on ‘Fusion/Protein’ was associated with being born outside NZ and being of non-European ethnicity, particularly Asian. High scores on the ‘Health conscious’ dietary pattern showed the highest odds of adherence to the pregnancy dietary guidelines. In this cohort of pregnant women different dietary patterns were associated with migration, ethnicity, socio-demographic characteristics, health behaviors and adherence to dietary guidelines.

    Childhood obesity has become a rising health problem, and because parental obesity is a basic risk factor for childhood obesity, biological factors have been especially considered in the complex etiology. Aspects of the family interaction, e.g., mother-child attachment, have not been the main focus. Our study tried to fill this gap by investigating whether there is a difference between children of obese and normal weight mothers in terms of mother-child attachment, and whether mother-child attachment predicts child's weight, in a sample of 31 obese and 31 normal weight mothers with children aged 19 to 58 months. Mother-child attachment was measured with the Attachment Q-Set. We found that (1) children of obese mothers showed a lower quality of mother-child attachment than children of normal weight mothers, which indicates that they are less likely to use their mothers as a secure base; (2) the attachment quality predicted child`s BMI percentile; and (3) the mother-child attachment adds incremental validity to the prediction of child's BMI beyond biological parameters (child's BMI birth percentile, BMI of the parents) and mother's relationship status. Implications of our findings are discussed.

    Maternal behaviour during the peri-partum period, albeit in differing forms, can be observed in all mammals, thus it must serve an important evolutionary purpose in enabling the successful raising of offspring. Maternal behaviour is comprised of a large suite of behaviours; in rodents these are generally defined as lactation, pup retrieval, maternal aggression and pup grooming. The maternal behaviour circuitry involves many brain regions including the hypothalamus and the limbi...

    Purpose: To study the impact of clinical predisposing factors on rectal normal tissue complication probability modeling using the updated results of the Dutch prostate dose-escalation trial. Methods and Materials: Toxicity data of 512 patients (conformally treated to 68 Gy [n = 284] and 78 Gy [n = 228]) with complete follow-up at 3 years after radiotherapy were studied. Scored end points were rectal bleeding, high stool frequency, and fecal incontinence. Two traditional dose-based models (Lyman-Kutcher-Burman (LKB) and Relative Seriality (RS) and a logistic model were fitted using a maximum likelihood approach. Furthermore, these model fits were improved by including the most significant clinical factors. The area under the receiver operating characteristic curve (AUC) was used to compare the discriminating ability of all fits. Results: Including clinical factors significantly increased the predictive power of the models for all end points. In the optimal LKB, RS, and logistic models for rectal bleeding and fecal incontinence, the first significant (p = 0.011-0.013) clinical factor was 'previous abdominal surgery.' As second significant (p = 0.012-0.016) factor, 'cardiac history' was included in all three rectal bleeding fits, whereas including 'diabetes' was significant (p = 0.039-0.048) in fecal incontinence modeling but only in the LKB and logistic models. High stool frequency fits only benefitted significantly (p = 0.003-0.006) from the inclusion of the baseline toxicity score. For all models rectal bleeding fits had the highest AUC (0.77) where it was 0.63 and 0.68 for high stool frequency and fecal incontinence, respectively. LKB and logistic model fits resulted in similar values for the volume parameter. The steepness parameter was somewhat higher in the logistic model, also resulting in a slightly lower D{sub 50}. Anal wall DVHs were used for fecal incontinence, whereas anorectal wall dose best described the other two endpoints

    Introduction Law 12.303/10 requires hearing screening in newborns before hospital discharge to detect possible hearing problems within the first three months after birth. If the newborn fails the test or presents signs of risk for hearing loss, it must undergo a retest and monitoring during the first year of life. In practice, this often does not happen. Objective To identify, in a group of mothers of children with risk factors for hearing loss, the determining reasons for non-compliance with the auditory retest. Method This is a cross-sectional quantitative study. For data collection, we handed a semi-structured questionnaire to 60 mothers of babies at risk for hearing loss who did not attend the hearing retest after hospital discharge. The questionnaire investigated their age, education, marital status, level of knowledge about the hearing screening, and reasons for non-compliance with the retest. We compared and analyzed data using the Chi-square test at a significance level of 0.05%. Results Our study found that 63% of the respondents were unaware of the hearing screening and most did not receive guidance on testing during prenatal care; 30% of participants stated forgetting as the reason for not attending the retest. There was no significant relationship between age, education, and marital status regarding knowledge about the test and the non-compliance with the retest. Conclusion Identified as the most significant determining factors for non-compliance with the newborn hearing screening retest were the surveyed mothers' forgetting the date, and their ignorance as to the importance of retesting.

    Objective: To analyze the maternal and infantile high risk factors of neonatal asphyxia, explore the key point of maternal and infantile health care during perinatal period in the region. Methods: A retrospective analysis was used to statistically analyze the maternal and infantile high risk factors of neonates with asphyxia who were bom in obstetrical department of the hospital from January to December in 2009. Results: 9 632 neonates were born in obstetrical department of the hospital in 2009, 157 neonates were found with asphyxia,the incidence was 1.63%. All the neonates with asphyxia had high risk factors during perinatal period, the proportions of maternal factors,fetal and neonatal factors, placental and umbilical factors and intrapartum factors were 24. 84%, 66. 24%, 25.48% and 24. 84%, respectively. Fetal and neonatal factors ranked the first among the neonates with asphyxia, including 91 premature infants, 85 low birth weight infants and 13 infants of retarded birth, twin pregnancy, macrosomia and congenital malformations. 7 neonates were found with severe asphyxia, accounting for 0. 07%. 3 neonates were born at 29 gestational weeks, 1 neonate was born at 35 gestational weeks whose body weight was 1 300 g, 1 neonate was born at 34 gestational weeks and found with placental abruption and thin umbilical cord, 2 neonates were found with congenital malformations (congenital pulmonary hypoplasia, pleural effusion) . Conclusion: Premature infants and low birth weight infants become to be the principal cause of neonatal asphyxia in the region, resuscitation of premature infants should become the key point of resuscitation training. Congenital malformation is a main factor of severe neonatal asphyxia, watching out for the existence of congenital malformations in the course of resuscitation can improve prognosis and prevent medical disputes.%目的:分析新生儿室息母婴高危因素,探讨该地区围产期母婴保健重点.方法:采用

    Infants exposed to maternal HIV infection who remain HIV-uninfected (HIV-exposed/uninfected; HIV-EU) may be at increased risk of growth retardation, which could be due both to directly HIV-related effects and to socio-economic factors overrepresented among HIV-positive women. To investigate growth development at 9-12 months of age in HIV-EU infants participating in prevention of mother-to-child transmission (PMTCT) care compared to HIV unexposed (HIV-U) infants in relation to socio-economic conditions. Anthropometric and socio-economic data were collected retrospectively from PMTCT registers (for HIV-EU infants), with HIV-U controls recruited at measles vaccination at public health facilities in Ethiopia. Growth was compared with regard to HIV exposure and socio-economic variables in multivariate regression analysis. The following growth measurements were found for 302 HIV-EU and 358 HIV-U infants at 9-12 months of age, respectively: mean weight-for-age z-score (WAZ) 0.04 and -0.21, p education (p education (p = 0.019). Lower LAZ was associated with male sex (p education (p education (p = 0.014). At 9-12 months of age, HIV-EU infants had non-inferior growth and higher mean WAZ than HIV-U controls. Poor growth development was associated with socio-economic factors. This suggests health benefits from PMTCT participation for infant growth. Similar interventions could be considered for Ethiopian infants, irrespective of HIV exposure, with a particular focus on children with poor socio-economic status.

    2016-04-01

    Full Text Available Background/Aims: Preterm birth (PTB and low birth weight (LBW significantly influence mortality and morbidity of the offspring in early life and also have long-term consequences in later life. A better understanding of the molecular mechanisms of preterm birth could provide new insights regarding putative preventive strategies. Metabolomics provides a powerful analytic tool to readout complex interactions between genetics, environment and health and may serve to identify relevant biomarkers. In this study, the association between 163 targeted maternal blood metabolites and gestational age was investigated in order to find candidate biomarkers for PTB. Methods: Five hundred twenty-three women were included into this observational study. Maternal blood was obtained before delivery. The concentration of 163 maternal serum metabolites was measured by flow injection tandem mass spectrometry. To find putative biomarkers for preterm birth, a three-step analysis was designed: bivariate correlation analysis followed by multivariable regression analysis and a comparison of mean values among gestational age groups. Results: Bivariate correlation analysis showed that 2 acylcarnitines (C16:2, C2, 1 amino acids (xLeu, 8 diacyl-PCs (PCaaC36:4, PCaaC38:4, PCaaC38:5, PCaaC38:6, PCaaC40:4, PCaaC40:5, PCaaC40:6, PCaaC42:4, and 1 Acylalkyl-PCs (PCaeC40:5 were inversely correlated with gestational age. Multivariable regression analysis confounded for PTB history, maternal body mass index (BMI before pregnancy, systolic blood pressure at the third trimester, and maternal body weight at the third trimester, showed that the diacyl-PC PCaaC38:6 was the only metabolite inversely correlated with gestational age. Conclusions: Maternal blood concentrations of PCaaC38:6 are independently associated with gestational age.

  11. Maternally acquired runt disease.

    1973-01-19

    Without altering the structural integrity of the placenta by irradiation or drugs, we have shown that it is possible to immunize females both adoptively and actively against the paternally inherited transplantation antigens of their fetuses. Such immunization causes a high incidence of runt disease among the litters. Although the putative chimeric status of the affected offspring has yet to be confirmed, the results of our experiments support the thesis that runt disease is caused by the activities of "unwanted" immigrant lymphocytes from the maternal circulation. Our results suggest that immunologically activated cells are more likely to cross the placenta than normal cells and that this greater mobility may not be related to the immunologic specificity of the activated cells. Two factors may have contributed to the apparent failure of numerous previous attempts to demonstrate the capacity of transplantation immunity to affect the well-being of a fetus or, more correctly, its placenta, in the way that might be expected of a homograft. (i) Investigators were preoccupied with obtaining a classic type of rejection, in utero, analogous to the rejection of an orthotopic skin homograft. The birth of consistently healthy-looking litters, interpreted as a failure of the experiment, convinced the investigators of the efficacy of nature's solution of the homograft problem and there was no reason for them to suspect its possible limitations. Observation of the litters for several weeks might have uncovered the phenomenon of maternally induced runt disease. (ii) Most investigators resorted to hyperimmunization of the mothers. This would have facilitated the synthesis of protective isoantibodies capable of interfering with the expression of the potentially harmful cellular immune response (6). Ever since the abnormalities of runt disease were first described they have repeatedly been compared to those observed in patients with certain lymphomas (17). Various theories have been

    Early life environments interact with genotype to determine stable phenotypic outcomes. Here we examined the influence of a variant in the brain-derived neurotropic factor (BDNF) gene (Val66Met), which underlies synaptic plasticity throughout the central nervous system, on the degree to which antenatal maternal anxiety associated with neonatal DNA methylation. We also examined the association between neonatal DNA methylation and brain substructure volume, as a function of BDNF genotype. Infant, but not maternal, BDNF genotype dramatically influences the association of antenatal anxiety on the epigenome at birth as well as that between the epigenome and neonatal brain structure. There was a greater impact of antenatal maternal anxiety on the DNA methylation of infants with the methionine (Met)/Met compared to both Met/valine (Val) and Val/Val genotypes. There were significantly more cytosine-phosphate-guanine sites where methylation levels covaried with right amygdala volume among Met/Met compared with both Met/Val and Val/Val carriers. In contrast, more cytosine-phosphate-guanine sites covaried with left hippocampus volume in Val/Val infants compared with infants of the Met/Val or Met/Met genotype. Thus, antenatal Maternal Anxiety × BDNF Val66Met Polymorphism interactions at the level of the epigenome are reflected differently in the structure of the amygdala and the hippocampus. These findings suggest that BDNF genotype regulates the sensitivity of the methylome to early environment and that differential susceptibility to specific environmental conditions may be both tissue and function specific.

    2016-01-01

    Enrico Modigliani (1877-1931) was an Italian paediatrician of the early Twentieth century whose work anticipated modern concepts of maternal and child health. Convinced of the importance of creating a network of health and social care for children born out-of-wedlock, he began by providing care to single mothers and their babies at his home on Sundays. In 1918, in Rome, he established the Institution for Maternal Assistance, which aim was to provide single mothers with basic health information as well as tools to face their socioeconomic situation. The Opera encouraged breastfeeding and maternal acknowledgement of the child and promoted the establishment of lactation rooms and nurseries within factories. Moreover, women were supported to find a job which was compatible with their situation. In the first five years of activity, over 1,000 unmarried women were assisted; 95% of them acknowledged their children and 52% found a job. The infant mortality rate fell to 11%, which was much lower than the 35% observed at the time among the social classes which Modigliani called the most miserable. This article reviews Modigliani's paper, in which the paediatrician reported the first five years of activity of the Institution of Maternal Assistance and where he largely focused on the social factors surrounding illegitimate motherhood. The paper was structured like a modern scientific report, with photographic documentation and statistical data, and proposed a point of view regarding social inequality which is surprisingly up-to-date.

Women who had a previous preterm birth have 63% increased odds of stillbirth in singleton pregnancies and 75% increased odds in twins as compared to those who did not have a preterm birth in a prior pregnancy (AOR = 1.63, 95% CI = 1.41–1.88 and AOR = 1.75, 95% CI = 1.20–2.56, respectively. The most significant risk factor for stillbirth in singleton pregnancies was uterine bleeding (AOR = 5.89, 95% CI = 5.13–6.76. In twin pregnancies, it was the condition hydramnios/oligohydramnios (AOR = 4.72, 95% CI = 3.70–6.02. Eclampsia was associated with a heightened risk of stillbirth in singletons (AOR = 2.45, 95% CI = 1.41–4.12, but not in twins (AOR = 0.96, 95% CI = 0.13–7.00. Black mothers were more likely than white to experience stillbirth (AOR = 2.10, 95% CI = 1.99–2.22 for singletons and AOR = 1.51, 95% CI = 1.27–1.79 for twins. Conclusion. Stillbirth is a vital public health issue and its etiology is not well understood. Previous history of preterm birth was found to be associated with future stillbirth. Targeted early medical and obstetric care and interventions among women with preterm birth history may potentially reduce the likelihood of stillbirth.

    Objective This study examines how emotion regulation deficits in the area of anger arousal and reactivity are associated with child abuse potential in mothers with substance use and depressive disorders in order to identify targeted areas for prevention and treatment. Methods A sample of 152 urban mothers was interviewed on measures of substance use, diagnosis of depression, anger arousal and reactivity, and child abuse potential. Results Linear hierarchical regressions revealed that anger arousal and reactivity exceeded diagnostic and demographic variables in predicting maternal child abuse potential. Additionally, anger arousal and reactivity was found to be a partial mediator of the relationship between diagnostic category and child abuse potential. Conclusions Findings are discussed in relation to a multifaceted model of child abuse potential which broadens the existing literature to include an examination of depression and emotion regulation in order to more fully understand how substance use and child abuse potential are linked. Practice implications Models and approaches which help clients to manage and regulate difficult feeling states, specifically anger, could be helpful, and may be most readily applied in such populations.

    2012-02-01

    Hemorrhage remains as one of the top 3 obstetrics related causes of maternal mortality, with most deaths occurring within 24-48 hours of delivery. Although hemorrhage related maternal mortality has declined globally, it continues to be a vexing problem. More specifically, the developing world continue to shoulder a disproportionate share of hemorrhage related deaths (99%) compared with industrialized nations (1%). Given the often preventable nature of death from hemorrhage, the cornerstone of effective mortality reduction involves risk factor identification, quick diagnosis, and timely management. In this monograph we will review the epidemiology, etiology, and preventative measures related to maternal mortality from hemorrhage.

    Bone marrow-derived mesenchymal stem cells (MSCs) have contributed to the improvement of diabetic nephropathy (DN); however, the actual mediator of this effect and its role has not been characterized thoroughly. We investigated the effects of MSC therapy on DN, focusing on the paracrine effect of renal trophic factors, including exosomes secreted by MSCs. MSCs and MSC-conditioned medium (MSC-CM) as renal trophic factors were administered in parallel to high-fat diet (HFD)-induced type 2 diabetic mice and streptozotocin (STZ)-induced insulin-deficient diabetic mice. Both therapies showed approximately equivalent curative effects, as each inhibited the exacerbation of albuminuria. They also suppressed the excessive infiltration of BMDCs into the kidney by regulating the expression of the adhesion molecule ICAM-1. Proinflammatory cytokine expression (e.g., TNF-α) and fibrosis in tubular interstitium were inhibited. TGF-β1 expression was down-regulated and tight junction protein expression (e.g., ZO-1) was maintained, which sequentially suppressed the epithelial-to-mesenchymal transition of tubular epithelial cells (TECs). Exosomes purified from MSC-CM exerted an anti-apoptotic effect and protected tight junction structure in TECs. The increase of glomerular mesangium substrate was inhibited in HFD-diabetic mice. MSC therapy is a promising tool to prevent DN via the paracrine effect of renal trophic factors including exosomes due to its multifactorial action. PMID:27721418

    Full Text Available Abstract Background Tanzania has one of the highest maternal mortality ratios in sub-Saharan Africa. Due to the paucity of epidemiological information on maternal deaths, and the high maternal mortality estimates found earlier in the study area, our objective was to assess determinants of maternal deaths in a rural setting in the highlands of northern Tanzania by comparing the women dying of maternal causes with women from the same population who had attended antenatal clinics in the same time period. Methods A case-control study was done in two administrative divisions in Mbulu and Hanang districts in rural Tanzania. Forty-five cases of maternal death were found through a comprehensive community- and health-facility based study in 1995 and 1996, while 135 antenatal attendees from four antenatal clinics in the same population, geographical area, and time-span of 1995–96 served as controls. The cases and controls were compared using multivariate logistic regression analyses. Odds ratios, with 95% confidence intervals, were used as an approximation of relative risk, and were adjusted for place of residence (ward and age. Further adjustment was done for potentially confounding variables. Results An increased risk of maternal deaths was found for women from 35–49 years versus 15–24 years (OR 4.0; 95%CI 1.5–10.6. Women from ethnic groups other than the two indigenous groups of the area had an increased risk of maternal death (OR 13.6; 95%CI 2.5–75.0. There was an increased risk when women or husbands adhered to traditional beliefs, (OR 2.1; 95%CI 1.0–4.5 and (OR 2.6; 95%CI 1.2–5.7, respectively. Women whose husbands did not have any formal education appeared to have an increased risk (OR 2.2; 95%CI 1.0–5.0. Conclusion Increasing maternal age, ethnic and religious affiliation, and low formal education of the husbands were associated with increased risk of maternal death. Increased attention needs to be given to formal education of both

    Expenditure on dental and oral health services in Australia is $3.4 billion AUD annually. This is the sixth highest health cost and accounts for 7 % of total national health expenditure. Approximately 49 % of Australian children aged 6 years have caries experience in their deciduous teeth and this is rising. The aetiology of dental caries involves a complex interplay of individual, behavioural, social, economic, political and environmental conditions, and there is increasing interest in genetic predisposition and epigenetic modification. The Oral Health Sub-study; a cross sectional study of a birth cohort began in November 2012 by examining mothers and their children who were six years old by the time of initiation of the study, which is ongoing. Data from detailed questionnaires of families from birth onwards and data on mothers' knowledge, attitudes and practices towards oral health collected at the time of clinical examination are used. Subjects' height, weight and mid-waist circumference are taken and Body Mass Index (BMI) computed, using an electronic Bio-Impedance balance. Dental caries experience is scored using the International Caries Detection and Assessment System (ICDAS). Saliva is collected for physiological measures. Salivary Deoxyribose Nucleic Acid (DNA) is extracted for genetic studies including epigenetics using the SeqCap Epi Enrichment Kit. Targets of interest are being confirmed by pyrosequencing to identify potential epigenetic markers of caries risk. This study will examine a wide range of potential determinants for childhood dental caries and evaluate inter-relationships amongst them. The findings will provide an evidence base to plan and implement improved preventive strategies.

    Pregnancy increases the risk of thrombosis four- to five-fold. Seventy-five to eighty percent of pregnancy-related thrombotic events are venous and twenty to -twenty-five percent are arterial. The main reason for the increased risk is hypercoagulability. Women are hypercoagulable because they have evolved so that they are protected against the bleeding challenges of pregnancy, miscarriage, or childbirth. Both genetic and acquired risk factors can further increase the risk of thrombosis. The maternal consequences of thrombosis of pregnancy include permanent vascular damage, disability, and death. While the maternal outcomes of thrombosis can be modified by anticoagulation therapy, management of thrombosis during pregnancy is the subject of another paper in this issue (see paper by B. Konkle). This review will focus on the epidemiology, pathophysiology, risk factors, and maternal consequences of thrombosis in pregnancy.

    Full Text Available OBJECTIVE: We investigated associations between maternal postpartum distress covering anxiety, depression and stress and childhood overweight. METHODS: We performed a prospective cohort study, including 21,121 mother-child-dyads from the Danish National Birth Cohort (DNBC. Maternal distress was measured 6 months postpartum by 9 items covering anxiety, depression and stress. Outcome was childhood overweight at 7-years-of age. Multiple logistic regression analyses were performed and information on maternal age, socioeconomic status, pre-pregnancy BMI, gestational weight gain, parity, smoking during pregnancy, paternal BMI, birth weight, gestational age at birth, sex, breastfeeding and finally infant weight at 5 and 12 month were included in the analyses. RESULTS: We found, that postpartum distress was not associated with childhood risk of overweight, OR 1.00, 95%CI [0.98-1.02]. Neither was anxiety, depression, or stress exposure, separately. There were no significant differences between the genders. Adjustment for potential confounders did not alter the results. CONCLUSION: Maternal postpartum distress is apparently not an independent risk factor for childhood overweight at 7-years-of-age. However, we can confirm previous findings of perinatal determinants as high maternal pre-pregnancy BMI, and smoking during pregnancy being risk factors for childhood overweight.

    This study was aimed on comparing the degree of association between social-cultural factors and maternal or perinatal morbidity and/or mortality of the adolescent. A paired case-control study was designed with adolescent in puerperal immediate stage affiliated to the Mexican Institute of Social Security from Tabasco, Tlaxcala and Northern Veracruz, that were adjusted to the selection criteria of the sample, between June of 1998 and February of 1999. Two groups were integrated, cases, with adolescent in puerperal immediate stage affected (with maternal or perinatal morbidity and/or mortality) and controls, with adolescent not affected in puerperal immediate stage. Information concerned to biological and social-cultural risk factors from each subject was obtained applying a validated survey (EFRASEMA 1) and checking their clinical file, whose information was poured in a database (EFRASEMA 2). Interviewers did not know the outcome of the study, which in turn assured the blindness of the information. Once data was obtained, subjects were assigned to each group of study. Matching factors were age, nutritional status, intergenesic interval and previous pregnancy systemic pathology. Proportion of subjects, cases and controls; with or without social-cultural risk factors was determined. The risk of maternal or perinatal morbidity and/or mortality in the exposed subjects was estimated by odds ratio (OR) and the differences inferred through Mantel and Haenszel chi 2 and Fisher's exact tests (confidence intervals alpha = 0.05 and beta = 0.2). There was a sample of 486 subject, 44 were eliminated due to insufficient data. Studied population was integrated finally with 221 cases and 221 paired controls 1: 1. 71.950% of participants were married, 22.62% in free union, 4.98% single and 0.45% separate, average global age was 17.98 +/- 1.39 years. The inferential analysis showed an OR 0.64 (Cornfield 95% confidence limits: 0.40 < OR < 1.03, p = 0.0510600) concerning desired

    Full Text Available To evaluate maternal heart disease as a cause or complicating factor for severe morbidity in the setting of the Brazilian Network for Surveillance of Severe Maternal Morbidity.Secondary data analysis of this multicenter cross-sectional study was implemented in 27 referral obstetric units in Brazil. From July 2009 to June 2010, a prospective surveillance was conducted among all delivery hospitalizations to identify cases of severe maternal morbidity (SMM, including Potentially Life-Threatening Conditions (PLTC and Maternal Near Miss (MNM, using the new criteria established by the WHO. The variables studied included: sociodemographic characteristics, clinical and obstetric history of the women; perinatal outcome and the occurrence of maternal outcomes (PLTC, MNM, MD between groups of cardiac and non-cardiac patients. Only heart conditions with hemodynamic impact characterizing severity of maternal morbidity were considered. 9555 women were included in the Network with severe pregnancy-related complications: 770 maternal near miss cases and 140 maternal death cases. A total of 293 (3.6% cases were related to heart disease and the condition was known before pregnancy in 82.6% of cases. Maternal near miss occurred in 15% of cardiac disease patients (most due to clinical-surgical causes, p<0.001 and 7.7% of non-cardiac patients (hemorrhagic and hypertensive causes, p<0.001. Maternal death occurred in 4.8% of cardiac patients and in 1.2% of non-cardiac patients, respectively.In this study, heart disease was significantly associated with a higher occurrence of severe maternal outcomes, including maternal death and maternal near miss, among women presenting with any severe maternal morbidity.

  6. Genetic, maternal and placental factors in the association between birth weight and physical fitness: a longitudinal twin study.

    Robbert N H Touwslager

    Full Text Available BACKGROUND: Adult cardiorespiratory fitness and muscle strength are related to all-cause and cardiovascular mortality. Both are possibly related to birth weight, but it is unclear what the importance is of genetic, maternal and placental factors in these associations. DESIGN: Peak oxygen uptake and measures of strength, flexibility and balance were obtained yearly during adolescence (10-18 years in 114 twin pairs in the Leuven Longitudinal Twin Study. Their birth weights had been collected prospectively within the East Flanders Prospective Twin Survey. RESULTS: We identified linear associations between birth weight and adolescent vertical jump (b = 1.96 cm per kg birth weight, P = 0.02, arm pull (b = 1.85 kg per kg birth weight P = 0.03 and flamingo balance (b = -1.82 attempts to stand one minute per kg birth weight, P = 0.03. Maximum oxygen uptake appeared to have a U-shaped association with birth weight (the smallest and largest children had the lowest uptake, P = 0.01, but this association was no longer significant after adjustment for parental BMI. Using the individual twin's deviation from his own twin pair's average birth weight, we found positive associations between birth weight and adolescent vertical jump (b = 3.49, P = 0.0007 and arm pull (b = 3.44, P = 0.02. Δ scores were calculated within the twin pairs as first born twin minus second born twin. Δ birth weight was associated with Δ vertical jump within MZ twin pairs only (b = 2.63, P = 0.009, which indicates importance of placental factors. CONCLUSIONS: We found evidence for an association between adolescent physical performance (strength, balance and possibly peak oxygen uptake and birth weight. The associations with vertical jump and arm pull were likely based on individual, more specifically placental (in the case of vertical jump factors. Our results should be viewed as hypothesis-generating and need confirmation, but potentially support preventive strategies to optimize

    Full Text Available Objectives: To comparatively analyze maternal and fetal factors and quality markers of blood samples in a public umbilical cord blood bank. Method: This is a cross-sectional descriptive study that revisited 458 records of donations from September 2009 to March 2013 at the Hemocentro de Santa Catarina. The means of markers were used to define cutoff points for the quality of cord blood. Results: Most donations came from women with ages between 18 and 29 years (62.8%, gestational age ≥ 40 weeks (55.2%, vaginal delivery (51.3%, primiparous (41.4%, and with male newborns (54.4% weighing between 3000 and 3499 g (41.8%. The volume of the dona- tions ranged from 71.6 to 275.2 mL, the total nucleated cell count ranged from 4.77 × 108 to 31.0 × 108 cells and CD34+ cells ranged from 0.05 to 1.23%. There were statistically significant differences in the volume with respect to gestation age > 38 weeks (p-value = 0.001, cesarean section (p-value 3500 g (p-value 3500 g (p-value < 0.001. There was no statistically significant difference between the variables and the percentage of CD34+ cells. Conclusions: Delivery route and birth weight influence the volume of cord blood and the total nucleated cell count. Gestational age influences only the volume of cord blood.

    Although medical literature on social inequalities in perinatal health is qualitatively heterogeneous, it is quantitatively important and reveals the existence of a social gradient in terms of perinatal risk. However, published data regarding maternal health, if also qualitatively heterogeneous, are relatively less numerous. Nevertheless, it appears that social inequalities also exist concerning severe maternal morbidity as well as maternal mortality. Analyses are still insufficient to understand the mechanisms involved and explain how the various dimensions of the women social condition interact with maternal health indicators. Inadequate prenatal care and suboptimal obstetric care may be intermediary factors, as they are related to both social status and maternal outcomes, in terms of maternal morbidity, its worsening or progression, and maternal mortality.

    Neonatal maternal deprivation (NMD) increases gut paracellular permeability (GPP) through mast cells and nerve growth factor (NGF), and modifies corticotrophin-releasing factor (CRF) and corticosterone levels. CRF, corticosterone and mast cells are involved in stress-induced mucosal barrier impairment. Consequently, this study aimed to specify whether corticosteronaemia and colonic expression of both preproCRF and CRF are modified by NMD, and to determine if altered expression may participate in the elevated GPP in connection with NGF and mast cells. Male Wistar rat pups were either separated from postnatal days 2-14, or left undisturbed with their dam. At 12 weeks of age, adult rats were treated with mifepristone (an antagonist of corticoid receptors), alpha-helical CRF((9-41)) (a non-specific CRF receptor antagonist), or SSR-125543 (CRF-R(1) receptor antagonist). We also determined corticosteronaemia and both colonic preproCRF and CRF expression. Then, control rats were treated by CRF, doxantrazole (mast cell stabilizer), BRX-537A (a mast cell activator) and anti-NGF antibody. NMD did not modify colonic CRF level but increased colonic preproCRF expression and corticosteronaemia. Peripheral CRF, via CRF-R(1) receptor, but not corticosterone, was involved in the elevated GPP observed in these rats, through a mast-cell-mediated mechanism, since the increase of GPP induced by exogenous CRF was abolished by doxantrazole. Anti-NGF antibody treatment also reduced the elevated GPP induced by CRF or BRX-537A. CRF acts through CRF-R(1) receptors to stimulate NGF release from mast cells, which participates in the elevated GPP observed in NMD adult rats. This suggests that early traumatic experience induced neuro-endocrine dysfunction, involved in alterations of gut mucosal barrier.

    Records of gestation length and birth weight on 1522 live single births (from 1958 to 1976) of Holstein calves were from 81 sires and 552 dams. Average gestation length was 282.3 days, and average birth weight was 42.9 kg. Male calves were carried 1.7 days longer than female calves and weighed 2.9 kg more at birth. Both gestation length and birth weight increased with parity. Calves born in spring and summer were carried shorter times and weighed less than those born in fall and winter. Heritabilities of gestation length and birth weight as progeny traits were .73 and .51 and as maternal traits were .19 and .26. Genetic correlations between gestation length and birth weight were .46 as a progeny trait and .35 as a maternal trait. Genetic correlations between progeny traits and maternal traits were negative. The phenotypic correlation between gestation length and birth weight was .37, and environmental correlation was .30.

    Results: During the defined period incidence of Eclampsia was 3.2 per 1000 deliveries. Maternal death occurred in 8.4% of patients and still birth in 18.8%. Inadequate and delayed initiation of treatment and preterm deliveries was found to be associated with poor maternal and fetal outcome. As the time interval between and lsquo;onset of fit and delivery' increased, chances of adverse outcome also increased. However, age, parity, onset of seizures before, during or after delivery was not found to have any effect on maternal and fetal outcome. Conclusions: It can be concluded that better antenatal care, early recognition of disease, timely referral, early initiation of treatment and termination of eclamptic patients improves outcome. Management of eclamptic patients should be performed at tertiary care centres, where ICU facilities, NICU facilities and multidisciplinary units are available.

    Full Text Available Abstract Background Because of low copy repeats (LCRs and common inversion polymorphisms, the human chromosome 8p is prone to a number of recurrent rearrangements. Each of these rearrangements is associated with several phenotypic features. We report on a patient with various clinical malformations and developmental delay in connection with an inverted duplication event, involving chromosome 8p. Methods Chromosome analysis, multicolor banding analysis (MCB, extensive fluorescence in situ hybridization (FISH analysis and microsatellite analysis were performed. Results The karyotype was characterized in detail by multicolor banding (MCB, subtelomeric and centromere-near probes as 46,XY,dup(8(pter->p23.3::p12->p23.3::p23.3->qter. Additionally, microsatellite analysis revealed the paternal origin of the duplication and gave hints for a mitotic recombination involving about 6 MB in 8p23.3. Conclusion A comprehensive analysis of the derivative chromosome 8 suggested a previously unreported mechanism of formation, which included an early mitotic aberration leading to maternal isodisomy, followed by an inverted duplication of the 8p12p23.3 region.

    There is increasing evidence that human pregnancy outcome can be significantly compromised by suboptimal maternal nutritional status. Poor diet results in a maternal-fetal environment in which the teratogenicity of other insults such as alcohol might be amplified. As an example, there is evidence that zinc (Zn) can interact with maternal alcohol exposure to influence the risk for fetal alcohol spectrum disorders (FASD). Studies with experimental animals have shown that the teratogenicity of alcohol is increased under conditions of Zn deficiency, whereas its teratogenicity is lessened when animals are given Zn-supplemented diets or Zn injections before the alcohol exposure. Alcohol can precipitate an acute-phase response, resulting in a subsequent increase in maternal liver metallothionein, which can sequester Zn and lead to decreased Zn transfer to the fetus. Importantly, the teratogenicity of acute alcohol exposure is reduced in metallothionein knockout mice, which can have improved Zn transfer to the conceptus relative to wild-type mice. Consistent with the above, Zn status has been reported to be low in alcoholic women at delivery. Preliminary data from two basic science and clinical nutritional studies that are ongoing as part of the international Collaborative Initiative on Fetal Alcohol Spectrum Disorders support the potential role of Zn, among other nutritional factors, relative to risk for FASD. Importantly, the nutrient levels being examined in these studies are relevant to general clinical populations and represent suboptimal levels rather than severe deficiencies. These data suggest that moderate deficiencies in single nutrients can act as permissive factors for FASD, and that adequate nutritional status or intervention through supplementation may provide protection from some of the adverse effects of prenatal alcohol exposure.

    Background To evaluate maternal heart disease as a cause or complicating factor for severe morbidity in the setting of the Brazilian Network for Surveillance of Severe Maternal Morbidity. Methods and Findings Secondary data analysis of this multicenter cross-sectional study was implemented in 27 referral obstetric units in Brazil. From July 2009 to June 2010, a prospective surveillance was conducted among all delivery hospitalizations to identify cases of severe maternal morbidity (SMM), including Potentially Life-Threatening Conditions (PLTC) and Maternal Near Miss (MNM), using the new criteria established by the WHO. The variables studied included: sociodemographic characteristics, clinical and obstetric history of the women; perinatal outcome and the occurrence of maternal outcomes (PLTC, MNM, MD) between groups of cardiac and non-cardiac patients. Only heart conditions with hemodynamic impact characterizing severity of maternal morbidity were considered. 9555 women were included in the Network with severe pregnancy-related complications: 770 maternal near miss cases and 140 maternal death cases. A total of 293 (3.6%) cases were related to heart disease and the condition was known before pregnancy in 82.6% of cases. Maternal near miss occurred in 15% of cardiac disease patients (most due to clinical-surgical causes, pnear miss, among women presenting with any severe maternal morbidity. PMID:26650684

    Full Text Available Objectives: The objectives of this study is to evaluate the incidence of maternal deaths, causes responsible for maternal mortality, direct and indirect factors, and various preventable methods to reduce maternal mortality rate. Background: 95% of maternal deaths occur in Asia and Africa. The need for undertaking this study is to know the maternal mortality rate, analyze the causes and preventable factors of death occurring in the district of Bijapur, Karnataka, India. Methodology: It is a study of 2years from the Records of District Health Office and Institutions on maternal mortality from June 2011 to May 2013 in Bijapur. Results: In two years there were fifty eight maternal deaths and seventy nine thousand five hundred and sixty six live births, hence maternal mortality ratio was seventy three per lakh live births. Eighty two percent of maternal deaths occurred in families who belonged to Below Poverty Line. Prevalence of anemia in pregnancy was 79.3%. Severe anemia (Hemoglobin <7g% seen in 5.1% was the most common indirect cause of death. Forty three percent of the deaths occurred at private setups. Hemorrhage, Septicemia and Preeclampsia & Eclampsia were responsible for 44.82%, 15.51% and 6.89% respectively. Conclusion: Majority of the maternal deaths are preventable if these four delays are avoided: a Delay in identifying the problem. b Delay in seeking care. c Delay in reaching the referral institute. d Delay in getting treatment on reaching the referral institute.

    Maternity care is an essential component of family medicine, yet the number of residency graduates providing this care continues to decline. Residency programs have struggled to identify strategies to increase continuation of obstetric practice among graduates. Leaders in family medicine obstetrics previously proposed a tiered model of training to ensure adequate volume for those desiring to continue maternity care upon graduation. However, whether this approach will be successful is unknown. This study aimed to identify program characteristics and teaching methods that may influence residents to continue obstetrics practice upon graduation. A nationwide survey of family medicine residency program directors (PDs) was conducted as part of the 2013 CERA survey to characterize teaching in maternity care and identify program-level predictors of graduate continuation of obstetrics (OB). Family medicine programs, which were community-based, university-affiliated programs in the Midwest and West, contributed more trainees who continued to provide OB care upon graduation. Trainees at these programs received greater supervision by family medicine faculty preceptors on labor and delivery, reported at least 80 deliveries by graduates during residency, and experienced greater autonomy in decision-making during OB rotations. This study supports a targeted approach to teaching maternity care in family medicine residency programs. Prioritizing continuity delivery experiences and fostering resident independence are strategies toward promoting increased provision of obstetric care by family medicine graduates. Further research is needed to evaluate the impact of tiered or track systems in practice.

    Study Type - Prognosis (cohort series) Level of Evidence 2a What's known on the subject? and What does the study add? Preoperative thrombocytosis has been identified as a predictor of poor outcome in various cancer types. However, the prognostic role of platelet count in patients with invasive bladder cancer undergoing radical cystectomy is unknown. The present study demonstrates that preoperative thrombocytosis is an independent risk factor for decreased cancer-specific survival after radical treatment of invasive bladder cancer. We developed a new prognostic scoring model for cancer-specific outcomes after radical cystectomy including platelet count and established pathological risk factors. Consideration of platelet count in the final model increased its predictive accuracy significantly. Thrombocytosis may be a useful parameter to include within established international bladder cancer nomograms. •  To investigate the oncological significance of preoperative thrombocytosis in patients with invasive bladder cancer undergoing radical cystectomy, as it has been reported as a marker for aggressive tumour biology in a variety of solid tumours. •  The series comprised 258 patients undergoing radical cystectomy between 1999 and 2010 in whom different clinical and histopathological parameters were assessed. •  Elevated platelet count was defined as >450 × 10(9) /L. •  Based on regression estimates of significant parameters in multivariable analysis a new weighted scoring model was developed to predict cancer-specific outcomes. •  The median follow-up was 30 months (6-116). •  Of the 258 patients, 26 (10.1%) had elevated and 232 (89.9%) had normal platelet count. The 3-year cancer-specific survival in patients with normal and elevated platelet count was 61.5% and 32.7%, respectively (P thrombocytosis (2.68, 1.26-5.14; P= 0.011). •  The 3-year cancer-specific survival in patients with a score 0 (low risk), 1-2 (intermediate risk) and 3

    Full Text Available Background: Compared to HIV-infected children, relatively little has been described regarding the health status, particularly growth of HIV-exposed but uninfected children in resource-limited settings. This is particularly relevant with widespread implementation of the prevention of parent to child transmission program. Methods: At a tertiary care health institute in India, a cohort of 44 HIV-exposed but uninfected children were followed through 6 months of age. The anthropometric parameters weight, length, and head circumference were investigated at birth, 3 weeks, 6 weeks, 3 months, and 6 months point of time. The information on maternal characteristics such as HIV clinical staging, CD4 count, and maternal weight were recorded. The linear regression analysis was applied to estimate the influence of maternal characteristics on infant anthropometric parameters. Results: Anthropometric parameters (weight, length and head circumference were significantly reduced in uninfected new-borns of mothers in HIV Clinical stage III and IV and weight 50 kg. Analysis conducted to find the effect of maternal immunosuppression on infant growth reveals a significant difference at CD4 300 cells/mm 3 and not at established cut-off of CD4 350 cells/mm 3 . This trend of difference continued at 6 weeks, 3 months, and 6 months. The multiple linear regression analysis model demonstrated maternal HIV clinical stage and weight as predictors for birth weight and length, respectively. Conclusions: Advanced HIV disease in the mother is associated with poor infant growth in HIV-exposed, but uninfected children at a critical growth phase in life. These results underscore the importance, especially in resource-constrained settings, of early HIV diagnosis and interventions to halt disease progression in all pregnant women.

    Repeat teen pregnancy is a frequent issue and is considered an aggravating factor for increased maternal and fetal morbidity and social problems. The aim of the study was to identify factors associated with repeat teen pregnancy. A case-control study was conducted in 90 postpartum adolescents with more than one pregnancy (cases) and 90 adult women with a history of only one pregnancy during adolescence (controls). Statistical analysis used hierarchical logistic regression with 5% significance. Early sexual initiation (< 15 years), early age at first pregnancy (< 16 years), not raising the children themselves, and low family income (< one minimum wage) were associated with repeat teenage pregnancy, while partner change was inversely associated. Repeat teen pregnancy was mainly associated with reproductive and socioeconomic factors. Partner change appeared as a protective factor. Measures should be adopted during the postpartum period of teenage mothers in order to avoid repeat pregnancy.

    Objective To explore maternal factors for mental development among the children in poor rural minority area. Methods Totally 2007 pupils and their mothers were selected from 7 primary schools in the poor rural minority areas of Ningxia Hui Autonomous Region with random cluster sampling and surveyed with Piers-Harris Children's Self-Concept Scale, Infants-Junior Middle School Student Social-Life Ability Scale, Children's Loneliness Scale, Social Anxiety Scale for Children, the Parent Behavior Report, and a questionnaire including demographic information and maternal factors. Results The level of mental development of the children was significantly lower than that of the national norms. There was a significant difference in mental development between the children with mothers educated differently except social anxiety. Hierarchical linear regression analyses showed that maternal education had a significant effect on mental development of the children after adjustment for demographic status( B = - 0. 074 - 0. 106, P < 0. 05 ). The occupation of the mother had an effect on the mental development of the children. Maternal income was significantly correlated with the mental development of the children( r = -0. 088 -0. 134, P < 0. 05 ). Maternal inductive parenting pattern was most beneficial to the mental development of the children, whereas maternal indifferent pattern was most harmful. Conclusion The mental development of the children is generally at a low level and maternal education, occupation,income and parenting pattern play important roles in mental development of the children in poor rural minority area.%目的 探讨贫困民族地区母亲因素对儿童心理发展的影响.方法 分层整群抽样法抽取宁夏回族自治区固原市7所农村小学2 007名学生,利用Piers-Harris自我意识量表、婴儿-初中生社会生活能力量表、儿童孤独量表、儿童社交焦虑量表和自编问卷进行调查.结果 儿童心理发展总体偏

    Full Text Available Abstract Background Maternal viral infection during pregnancy is associated with an increase in the incidence of psychiatric disorders with presumed neurodevelopmental origin, including autism spectrum disorders and schizophrenia. The enhanced risk for developing mental illness appears to be caused by deleterious effects of innate immune response-associated factors on the development of the central nervous system, which predispose the offspring to pathological behaviors in adolescence and adulthood. To identify the immune response-associated soluble factors that may affect central nervous system development, we examined the effect of innate immune response activation by polyriboinosinic-polyribocytidylic acid (poly(I:C, a synthetic analogue of viral double-stranded RNA, on the expression levels of pro- and anti-inflammatory cytokines, chemokines and colony stimulating factors in fetal and postnatal mouse brain 6 h and 24 h after treatment. Methods C57BL/6J pregnant mice (gestational day 16 or newborn mice (postnatal day 4 received a single intraperitoneal injection of the synthetic analogue of viral double-stranded RNA poly(I:C (20 mg/kg. Thirty-two immune response-associated soluble factors, including pro- and anti-inflammatory cytokines, chemokines and colony stimulating factors, were assayed 6 h and 24 h after poly(I:C injection using multiplexed bead-based immunoassay (Milliplex Map and processed in a Luminex 100 IS instrument. Results Maternal exposure to poly(I:C at gestational day 16 induced a significant increase in cytokines interleukin (IL-1β, IL-7 and IL-13; chemokines monocyte chemoattractant protein 1 (MCP-1, macrophage inflammatory protein (MIP-1α, interferon gamma-induced protein (IP-10 and monokine induced by IFN-gamma (MIG; and in the colony stimulating factor vascular endothelial growth factor (VEGF in the fetal brain. IL-1β showed the highest concentration levels in fetal brains and was the only cytokine

    Full Text Available Background: China has made impressive progress towards the Millennium Development Goal (MDG for maternal and reproductive health, but ensuring that progress reaches all segments of the population remains a challenge for policy makers. The aim of this review is to map disadvantaged populations in terms of maternal health in China, and to explain the causes of these inequities to promote policy action. Methods: We searched PUBMED, Popline, Proquest and WanFang and included primary studies conducted in mainland China. Experts were also contacted to identify additional studies. Disadvantaged populations in terms of MDG 5 and the reasons for this disadvantage explored by authors were identified and coded based on the conceptual framework developed by the WHO Commission on the Social Determinants of Health. Results: In China, differences in maternal health service utilization and the maternal mortality ratio among different income groups, and among regions with different socio-economic development still exist, although these differences are narrowing. Groups with low levels of education and ethnic minorities utilize maternal health care less frequently and experience higher maternal mortality, although we could not determine whether these differences have changed in the last decade. Rural-to-urban migrants use maternal health care and contraception to a lower extent than permanent residents of cities, and differential maternal mortality shows a widening trend among these groups. Gender inequity also contributes to the disadvantaged position of women. Intermediary factors that explain these inequities include material circumstances such as long distances to health facilities for women living in remote areas, behavioral factors such as traditional beliefs that result in reduced care seeking among ethnic minorities, and health system determinants such as out-of-pocket payments posing financial barriers for the poor. Conclusions: Inequity in maternal

To identify complications in pregnancy, a childbirth which result in maternal death, and to identify opportunities for preventive intervention and understand the events leading to death; so that improving maternal health and reducing maternal mortality rate significantly. To analyze the causes and epidemiological amounts maternal mortality e.g. age parity, socioeconomic status and literacy. In order to reduce maternal mortality and to implement safe motherhood program and complications of pregnancy and to find out safe motherhood program. METHODS: The data collected was a retrograde by a proforma containing particulars of the diseased, detailed history and relatives were interviewed for additional information. The data collected was analysed. RESULTS: Maternal mortality rate in our own institution is 200/ 100,000 live births. Among 30 maternal deaths, 56% deaths (17 were among low socio - economic status, groups 60% deaths among unbooked 53.5% deaths more along illiterates evidenced by direct and indirect deaths about 25% of deaths were preventable. CONCLUSION: Maternal death is a great tragedy in the family life. It is crusade to know not just the medical cause of the death but the circumstances what makes these continued tragic death even more unacceptable is that deaths are largely preventable

    A 44-year-old man who drove a motorcycle experienced a collision with the side of another motorcycle. Because he had sustained a high-energy injury to the spinal cord, he was transferred to our hospital. His circulation was unstable, and received tracheal intubation in addition to thoracostomy for the hemothorax. Whole-body computed tomography (CT) revealed multiple fractures, right hemopneumothorax with pulmonary contusion, and minor liver injury. After infusing 5000 mL of lactated Ringer's solution and 10 units of blood, his circulation remained unstable. On a repeat CT examination, the left atrium was found to be compressed by a posterior mediastinal hematoma induced by the fracture of the thoracic spine, and a diagnosis of shock induced by multiple factors, including hemorrhagic, neurogenic, and obstructive mechanisms, was made. After obtaining stable circulation and respirations, internal fixation of the extremities and extubation were performed on the 12th hospital day. Chest CT performed on the 27th day showed the disappearance of compression of the left atrium by the hematoma.

  15. Factors Contributing to Maternal and Child Mortality Reductions in 146 Low- and Middle-Income Countries between 1990 and 2010.

    Full Text Available From 1990-2010, worldwide child mortality declined by 43%, and maternal mortality declined by 40%. This paper compares two sources of progress: improvements in societal coverage of health determinants versus improvements in the impact of health determinants as a result of technical change.This paper decomposes the progress made by 146 low- and middle-income countries (LMICs in lowering childhood and maternal mortality into one component due to better health determinants like literacy, income, and health coverage and a second component due to changes in the impact of these health determinants. Health determinants were selected from eight distinct health-impacting sectors. Health determinants were selected from eight distinct health-impacting sectors. Regression models are used to estimate impact size in 1990 and again in 2010. Changes in the levels of health determinants were measured using secondary data.The model shows that respectively 100% and 89% of the reductions in maternal and child mortality since 1990 were due to improvements in nationwide coverage of health determinants. The relative share of overall improvement attributable to any single determinant varies by country and by model specification. However, in aggregate, approximately 50% of the mortality reductions were due to improvements in the health sector, and the other 50% of the mortality reductions were due to gains outside the health sector.Overall, countries improved maternal and child health (MCH from 1990 to 2010 mainly through improvements in the societal coverage of a broad array of health system, social, economic and environmental determinants of child health. These findings vindicate efforts by the global community to obtain such improvements, and align with the post-2015 development agenda that builds on the lessons from the MDGs and highlights the importance of promoting health and sustainable development in a more integrated manner across sectors.

    Full Text Available Stress is an adaptive response that may involve adverse changes in the medium and long term. Research showed that maternal stress during pregnancy may have variables effects on the offspring development. The objective of this study was to describe the cognitive characteristics of children from Bogota- Colombia, whose mothers during neuropsychological consultation, reported stress during pregnancy as the only risk factor. Cognitive profiles are described from neuropsychological assessments, highlighting significant scores in the subtest and global indices of the WISC IV scale. It was foundthat children whose mothers suffer stress during pregnancy have deficits in attention, executive functions and processing speed.

    It is well recognized that adverse events in utero impair fetal development and lead to the development of obesity and metabolic syndrome in adulthood. To investigate the mechanisms linking impaired fetal growth to increased cholesterol, an important clinical risk factor characterizing the metabolic syndrome and cardiovascular disease, we examined the impact of maternal undernutrition on tumor necrosis factor-α (TNF-α)/c-jun N-terminal kinase (JNK) signaling pathway and the cholesterol 7α-hydroxylase (CYP7A1) expression in the livers of the offspring with a protein restriction model. The male offspring with intrauterine growth restriction (IUGR) caused by the isocaloric low-protein diet showed decreased liver weight at birth and augmented circulation and hepatic cholesterol levels at 40 weeks of age. Maternal undernutrition significantly upregulated cytokine TNF-α expression and JNK phospholytion levels in the livers from fetal age to adulthood. Elevated JNK phospholytion could be linked to downregulated hepatocyte nuclear factor-4α and CYP7A1 expression, subsequently led to higher hepatic cholesterol. This work demonstrated that intrauterine malnutrition-induced IUGR might result in intrinsic disorder in hepatic TNF-α/CYP7A1 signaling, and contribute to the development of hypercholesterolemia in later life.

    This longitudinal study examined the influence of parenting behaviors, well-being, and risk factors of low-income adolescent mothers on the cognitive and language abilities of children from infancy to age 3. Participants consisted of 1,240 mother-child dyads enrolled in the Early Head Start Research and Evaluation Project. Data were collected using structured interviews with the mothers and from videotaped mother-child interactions during play activities when children were approximately 14 months old and again at 36 months of age. Positive parenting behaviors exhibited toward the 14-month-old children predicted gains in both cognitive and language abilities more so than did maternal well-being, risk factors within the family setting, and demographic risk factors. Gains in cognitive abilities from infancy to age 3 were predicted by supportive parenting, higher family resources, and lower family conflict when children were infants. Gains in language abilities were predicted by supportive parenting, support for language and learning in the home environment, and higher family resources when children were infants. Finally, path analyses showed that maternal age had an indirect effect on child cognitive and language abilities at age 3 through effects on parenting behaviors. Older mothers were more likely to be supportive during play at age 14 months, which in turn promoted enhanced developmental outcomes at age 3. Implications for intervention and future research are discussed.

    Full Text Available Obesity in pregnancy may be associated with reduced placental transfer of 25-hydroxyvitamin D (25-OHD. The objective of this study was to examine associations between maternal BMI and maternal and cord blood levels of 25-OHD in full term neonates born to a single racial cohort residing at similar latitude. Secondary objectives were to examine associations between maternal glucose tolerance with maternal levels of 25-OHD and the relationship between cord blood 25-OHD levels and neonatal size.This study was conducted among participants of the Hyperglycemia and Adverse Pregnancy Outcomes (HAPO Study meeting the following criteria: residing at latitudes 41-43°, maternal white race, and gestational age 39-41 weeks. Healthy pregnant women underwent measures of height, weight, and a 75-g fasting oral glucose tolerance test (OGTT at approximately 28 weeks gestation. Maternal and cord blood sera were analyzed for total 25-OHD by HPLC tandem mass spectrometry. Statistical analyses included ANOVA and linear regression models.Maternal and cord blood (N = 360 mean levels (sd of 25-OHD were 37.2 (11.2 and 23.4 (9.2 ng/ml, respectively, and these levels were significantly different among the 3 field centers (ANOVA p< 0.001. Maternal serum 25-OHD was lower by 0.40 ng/ml for BMI higher by 1 kg/m2 (p<0.001 in an adjusted model. Maternal fasting plasma glucose, insulin sensitivity, and presence of GDM were not associated with maternal serum 25-OHD level when adjusted for maternal BMI. Cord blood 25-OHD was lower by 0.26 ng/ml for maternal BMI higher by 1 kg/m2 (p<0.004. With adjustment for maternal age, field center, birth season and maternal serum 25-OHD, the association of cord blood 25-OHD with maternal BMI was attenuated. Neither birth weight nor neonatal adiposity was significantly associated with cord blood 25-OHD levels.These results suggest that maternal levels of 25-OHD are associated with maternal BMI. The results also suggest that interpretation of

    Full Text Available The recent emphasis on humans as cooperative breeders invites new research on human family dynamics. In this paper we look at maternal guilt as a consequence of conditional maternal investment. Solicited texts written by Finnish mothers with under school-aged children in 2007 (n = 63 described maternal emotions perceived as difficult and forbidden. Content analysis of guilt-inducing situations showed that guilt arose from diverging interest and negotiations between the mother and child (i.e., classic parent-offspring conflict. Also cultural expectations of extensive and perpetual high-quality maternal investment or the “motherhood myth” induced guilt in mothers. We argue that guilt plays an important role in maternal-investment regulation. Maternal guilt is predicted to vary with social and cultural context but also to show universal characteristics due to parent-offspring conflict and allomaternal manipulation. Results are preliminary and intended to stimulate research into the mechanisms, gender differences and cultural variations of guilt and other social emotions in human parenting.

    Full Text Available OBJECTIVE: To study the prevalence of potentially life-threatening maternal conditions and near miss in Brazil according to maternal age. METHODS: A secondary analysis of the 2006 Brazilian demographic health survey database using a validated questionnaire to evaluate maternal morbidity with a focus on age extremes. The study included 5,025 women with at least 1 live birth in the 5-year reference period preceding their interviews. Three age range periods were used: 15-19 years (younger age, 20-34 years (control, and 35-49 years (advanced maternal age. According to a pragmatic definition, any woman reporting eclampsia, hysterectomy, blood transfusion, or admission to the intensive care unit during her pregnancy/childbirth was considered a near-miss case. The associations between age and severe maternal morbidity were further assessed. RESULTS: For the 6,833 reported pregnancies, 73.7% of the women were 20-34 years old, 17.9% were of advanced maternal age, and only 8.4% were of younger age. More than 22% of the women had at least one of the complications appraised, and blood transfusion, which was more prevalent among the controls, was the only variable with a significant difference among the age groups. The overall rate of maternal near miss was 21.1 per 1000 live births. There was a trend of higher maternal near miss with increasing age. The only significant risk factor identified for maternal near miss was a lower literacy level among older women. CONCLUSIONS: There is a trend towards worse results with increasing age. The investigation of the determinants of maternal near miss at the community level using an innovative approach through a demographic health survey is an example suggested for under-resourced settings.

    During mouse antral follicle development, the oocyte chromatin gradually transforms from a less condensed state with no Hoechst-positive rim surrounding the nucleolus (NSN) to a fully condensed chromatin state with a Hoechst-positive rim surrounding the nucleolus (SN). Compared with SN oocytes, NSN oocytes display a higher gene transcription activity and a lower rate of meiosis resumption (G2/M transition), and they are mostly arrested at the two-cell stage after in vitro fertilization. To explore the differences between NSN and SN oocytes, and the maternal factors required for oocyte developmental competence, we compared the whole-transcriptome profiles between NSN and SN oocytes. First, we found that the NSN and SN oocytes were different in their metabolic pathways. In the phosphatidylinositol signaling pathway, the SN oocytes tend to produce diacylglycerol, whereas the NSN oocytes tend to produce phosphatidylinositol (3,4,5)-trisphosphate. For energy production, the SN oocytes and NSN oocytes differed in the gluconeogenesis and in the synthesis processes. Second, we also found that the key genes associated with oocyte meiosis and/or preimplantation embryo development were differently expressed in the NSN and SN oocytes. Our results illustrate that during the NSN-SN transition, the oocytes change their metabolic activities and accumulate maternal factors for further oocyte maturation and post-fertilization embryo development.

    Preterm pregnancies account for approximately 10% of the total pregnancies and are associated with low birth weight (LBW) babies. Recent studies have shown that LBW babies are at an increased risk of developing brain disorders such as cognitive dysfunction and psychiatric disorders. Maternal nutrition, particularly, micronutrients involved in one-carbon metabolism (folic acid, vitamin B(12), and docosahexaenoic acid (DHA)) have a major role during pregnancy for developing fetus and are important determinants of epigenesis. A series of our studies in pregnancy complications have well established the importance of omega 3 fatty acids especially DHA. DHA regulates levels of neurotrophins like brain-derived neurotrophic factor and nerve growth factor, which are required for normal neurological development. We have recently described that in one carbon metabolic pathway, membrane phospholipids are major methyl group acceptors and reduced DHA levels may result in diversion of methyl groups toward deoxyribonucleic acid (DNA) ultimately resulting in DNA methylation. In this review, we propose that altered maternal micronutrients (folic acid, vitamin B(12)), increased homocysteine, and oxidative stress levels that cause epigenetic modifications may be one of the mechanisms that contribute to preterm birth and poor fetal outcome, increasing risk for behavioural disorders in children.

  6. Hydrogeomorphic Classification of Wetlands on Mt. Desert Island, Maine, Including Hydrologic Susceptibility Factors for Wetlands in Acadia National Park

    Nielsen, Martha G.

    2006-01-01

    The U.S. Geological Survey, in cooperation with the National Park Service, developed a hydrogeomorphic (HGM) classification system for wetlands greater than 0.4 hectares (ha) on Mt. Desert Island, Maine, and applied this classification using map-scale data to more than 1,200 mapped wetland units on the island. In addition, two hydrologic susceptibility factors were defined for a subset of these wetlands, using 11 variables derived from landscape-scale characteristics of the catchment areas of these wetlands. The hydrologic susceptibility factors, one related to the potential hydrologic pathways for contaminants and the other to the susceptibility of wetlands to disruptions in water supply from projected future changes in climate, were used to indicate which wetlands (greater than 1 ha) in Acadia National Park (ANP) may warrant further investigation or monitoring. The HGM classification system consists of 13 categories: Riverine-Upper Perennial, Riverine-Nonperennial, Riverine- Tidal, Depressional-Closed, Depressional-Semiclosed, Depressional-Open, Depressional-No Ground-Water Input, Mineral Soil Flat, Organic Soil Flat, Tidal Fringe, Lacustrine Fringe, Slope, and Hilltop/Upper Hillslope. A dichotomous key was developed to aid in the classification of wetlands. The National Wetland Inventory maps produced by the U.S. Fish and Wildlife Service provided the wetland mapping units used for this classification. On the basis of topographic map information and geographic information system (GIS) layers at a scale of 1:24,000 or larger, 1,202 wetland units were assigned a preliminary HGM classification. Two of the 13 HGM classes (Riverine-Tidal and Depressional-No Ground-Water Input) were not assigned to any wetlands because criteria for determining those classes are not available at that map scale, and must be determined by more site-specific information. Of the 1,202 wetland polygons classified, which cover 1,830 ha in ANP, 327 were classified as Slope, 258 were

    Full Text Available BACKGROUND: Psychological factors are known predictors of cardiovascular disease in many clinical settings, but data are lacking for HIV infection. We carried out a prospective cohort study to evaluate potential psychological predictors of preclinical and clinical vascular disease in HIV patients. METHODOLOGY/PRINCIPAL FINDINGS: HIV patients were consecutively enrolled. Demographics, viral and immune parameters and traditional cardiovascular predictors were considered; Intima-Media Thickness (c-IMT, continuous measure and Carotid Plaques (CPs, focal thickening ≥1.5 mm were investigated by B-mode ultrasonography; depressive symptoms by the Beck Depression Inventory (BDI-II, Type D personality (Distressed Personality or Type D by the DS14, alexithymia by the Toronto Alexithymia Scale (TAS-20. Vascular outcomes included transient ischemic attacks or stroke, acute coronary syndrome, myocardial or other organ infarction. We enrolled 232 HIV subjects, 73.9% males, aged 44.5±9.9 y, 38.2% with AIDS diagnosis, 18.3% untreated. Mean Nadir CD4 T-cell counts were 237.5±186.2/mmc. Of them, 224 (96.5% attended IMT measurements; 201 (86.6% attended both IMT assessment and psychological profiling. Mean follow-up was 782±308 days. Fifty-nine patients (29.4% had CPs at baseline. Nineteen patients (9.5% had ≥1 vascular event; 12 (6.0% died due to such events (n = 4 or any cause. At baseline cross-sectional multivariate analysis, increasing age, total cholesterol, current smoking and Alexithymia score≥50 were significantly associated with both increased cIMT (linear regression and CPs (logistic regression. At follow-up analysis, log-rank tests and Cox's regression revealed that only older age (p = 0.001, current smoking (p = 0.019 and alexithymia score≥50 (p = 0.013 were independently associated with vascular events. CONCLUSIONS/SIGNIFICANCE: In HIV-infected subjects, the Alexithymic trait emerges as a strong predictor of increased IMT, presence of CPs

    Addressing cultural factors that affect uptake of skilled maternity care is recognized as an important step in improving maternal and newborn health. This article describes a systematic review to examine the evidence available on the effects of interventions to provide culturally appropriate maternity care on the use of skilled maternity care during pregnancy, for birth or in the postpartum period. Items published in English, French and/or Spanish between 1 January 1990 and 31 March 2014 were considered. Fifteen studies describing a range of interventions met the inclusion criteria. Data were extracted on population and intervention characteristics; study design; definitions and data for relevant outcomes; and the contexts and conditions in which interventions occurred. Because most of the included studies focus on antenatal care outcomes, evidence of impact is particularly limited for care seeking for birth and after birth. Evidence in this review is clustered within a small number of countries, and evidence from low- and middle-income countries is notably lacking. Interventions largely had positive effects on uptake of skilled maternity care. Cultural factors are often not the sole factor affecting populations’ use of maternity care services. Broader social, economic, geographical and political factors interacted with cultural factors to affect targeted populations’ access to services in included studies. Programmes and policies should seek to establish an enabling environment and support respectful dialogue with communities to improve use of skilled maternity care. Whilst issues of culture are being recognized by programmes and researchers as being important, interventions that explicitly incorporate issues of culture are rarely evaluated. PMID:27190222

    Under Austrian law, precautionary maternity leave is a decree issued by the district public health physician. It forbids a pregnant woman to work and mandates immediate maternity leave. Regular maternity leave for all women employed in all jobs begins at 32 weeks of gestation. Women who work in workplaces deemed dangerous and women with a history of obstetric problems such as premature or growth-retarded babies from previous pregnancies are regularly 'sent' into precautionary maternity leave. The public health physicians of Tirol's nine administrative districts were interviewed and supplied data on precautionary maternity leave from their districts. In 100 women who attended the clinic for pregnancies at risk of the Obstetrics/Gynecology Department of Innsbruck University Hospital and who had already obtained precautionary maternity leave, the medical/administrative procedure was studied in each case and correlated with pregnancy outcome. The town district of Innsbruck and the district that comprises the suburbs of the provincial capital had the highest rates of precautionary maternity leave. The town district of Innsbruck had a rate of 24.3% of all pregnant women (employed and not employed) in precautionary maternity leave in 1997, whereas the whole province of Tirol had 13.4%. More than 80% of decrees for precautionary maternity leave are issued by district public health physicians on the basis of written recommendations from gynecologists. One third of women who are sent into precautionary maternity leave are issued the decree prior to 12 weeks of gestation - mostly cases of multiple pregnancies and women with previous miscarriages. The present system of precautionary maternity leave appears to work in the sense that most working pregnant women with risk factors are correctly identified - with most errors on the side of caution. As the system also helps employers - the employee's pay is paid from the federal family support fund and state insurance once she is in

    Childhood wasting although well studied elsewhere, it has not been well understood about in slum area of Nepal. This study aimed to assess effect of socio-demographic factors and child feeding practice in the determination of wasting among the children under five years of age in slum area of Nepal. A community based cross-sectional study was performed among 150 children under five years of age from the slum area of Nepal between 1st January and 28th February 2013 using simple random sampling techniques. Multivariate analyses were performed to determine factors associated with wasting controlling the potential confounders. In a total of 150 under five years children, the prevalence of wasting was 56 (37.33%). The current study demonstrated that children of mothers from dalit Adjusted Odds Ratio (OR) 11.5; 95% CI: 03.1 - 41.3), aadibasi/janajati (AOR 4.6; 95% CI: 1.2 - 17.0), illiterate mothers (AOR 3.6; 95% CI: 1.1 - 13.6), laborer mothers (AOR 2.1; 95% CI: 1.1-9.4), child age group 25-36 months (AOR 2.8; 95% CI: 1.5-5.3), multiple child birth order (AOR 10.0; 95% CI: 2.5-25.0), children who were not fed colostrums (AOR 15.0; 95% CI: 1.25-10.0) were more likely to develop wasting compared to their counterparts. As incremental childhood wasting is associated with maternal socio-demographic factors and child feeding practice, health promotion strategies should focus maternal socio-demographic factors, age of children and early initiation of breast feeding for the improved child nutrition in slum area of Nepal.

    In a previous paper we have pointed out that the common-translation-factor (CTF) method is the only one which, at present, and within the framework of the molecular model of atomic collisions, can be shown to be both convergent and computationally fast, even for many-electron systems. In this Communication we check that this second statement is correct, presenting, for the first time, a molecular calculation involving two-electron translation factors, for He/sup +/ + H collisions. A careful study of the sensitivity of the calculated cross sections to the choice of the CTF is performed, and conclusions on that sensitivity are drawn, for several types of processes.

    Full Text Available Background Studies introduce maternal and neonatal safety phenomena as important challenges to the public health, particularly in low-income countries. However, few researches are conducted on the identification of safety issues in maternity hospitals in Iraq. It was the first study on nurses’ perspectives on safety issues in Kurdistan, Iraq. Objectives The current study aimed to describe nurses’ perspectives on what constitutes a safe maternity service in Kurdistan, Iraq. Patients and Methods A qualitative design, based on a content analysis approach, was used. Ten Kurdish nurses who worked in the delivery room of Kurdistan, Iraq maternity hospital were recruited through purposive sampling. Semi-structured interviews were performed to collect data. All interviews were audiotaped and transcribed verbatim. Sampling continued to the level of data saturation. Data analysis was performed based on the steps suggested by Graneheim and Lundman. Results Thematic analysis led to the identification of six main categories including stressful job, lack of schedule and job description, providing care with limited resources, professional unaccountability, regional sociopolitical factors, and inadequate training. Conclusions Iraqi nurses identified factors such as limited health resources, lack of job description, and professional unaccountability as major safety issues in maternity services. These findings alarm the need to ensure the provision of females and neonates with appropriate care. This, however, would require coordination between Iraqi Kurdistan health authorities to provide midwifery care facilities, high-quality and relevant staff training, and an effective healthcare system in the maternity units.

    Background: Maternal mortality ratio in Ecuador is the only millennium goal on which national agencies are still making strong efforts to reach 2015 target. The purpose of the study was to process national maternal death databases to identify a specific association pattern of variable included in the death certificate. Design and methods: The study processed mortality databases published yearly by the National Census and Statistics Institute (INEC). Data analysed were exclusively maternal deaths. Data corresponds to the 2003-2013 period, accessible through INEC's website. Comparisons are based on number of deaths and use an ecological approach for geographical coincidences. Results: The study identified variable association into the maternal mortality national databases showing that to die at home or in a different place than a hospital is closely related to women's socioeconomic characteristics; there was an association with the absence of a public health facility. Also, to die in a different place than the usual residence could mean that women and families are searching for or were referred to a higher level of attention when they face complications. Conclusions: Ecuadorian maternal deaths showed Patterns of inequity in health status, health care provision and health risks. A predominant factor seems unclear to explain the variable association found processing national databases; perhaps every pattern of health systems development played a role in maternal mortality or factors different from those registered by the statistics system may remain hidden. Some random influences might not be even considered in an explanatory model yet.

    Licata, Maria; Zietlow, Anna-Lena; Träuble, Birgit; Sodian, Beate; Reck, Corinna

    High maternal emotional availability (EA) positively affects various domains of child development. However, the question of which factors promote or hinder maternal EA has not been investigated systematically. The present study investigated several maternal characteristics, namely maternal psychopathology, maternal attachment style insecurity, and theory of mind (ToM) as possible factors that influence maternal EA. The sample was comprised of 56 mothers and their preschool-aged children. Half of the mothers were diagnosed with postpartum depression and or anxiety disorders according to DSM-IV, and the other half were healthy controls. The results showed that both low maternal attachment style insecurity and high ToM skills significantly predicted maternal EA sensitivity, independently from maternal postpartum and concurrent psychopathology and education. Moreover, maternal attachment style insecurity fully mediated the link between maternal postpartum psychopathology and sensitivity. The findings suggest that maternal attachment style security can buffer negative effects of maternal psychopathology on maternal sensitivity in the mother-child interaction. © 2016 S.

    The change ΔR(x) of bond length R(x) for atom X in a molecule upon electronic transition can be derived from the intensities I(i) of the vibrational stretching progression v = 0 → i of the electronic absorption or emission spectrum. In many cases, a simple model is sufficient for a reasonable estimate of ΔR(x). For symmetric molecules, however, conceptual problems in the literature of many decades are evident. The breathing modes of various types of symmetric molecules X(n) and AX(n) (A at the center) are here discussed. In the simplest case of a harmonic vibration of the same mode in the initial and final electronic states, we obtain ΔR(x) ≈ [2S/(ωm(x))](1/2)/w(1/2) (all quantities in atomic units). ω and S are respectively the observed vibrational quanta and the Huang-Rhys factor (corresponding, e.g., to the vibrational intensity ratio I(1)/I(0) ≈ S), m(x) is the mass of vibrating atom X, and w is a topological factor for molecule X(n) or AX(n). The factor 1/w(1/2) in the expression for ΔR(x) must not be neglected. The spectra and bond length changes of several symmetric molecules AX(n) and X(n) are discussed. The experimental bond length changes correctly derived with factor 1/w(1/2) are verified by reliable quantum chemical calculations.

    To ensure the protection of drinking water an understanding of the catchment processes which can affect water quality is important as it enables targeted catchment management actions to be implemented. In this study factor analysis (FA) and comparing event mean concentrations (EMCs) with baseline values were techniques used to asses the relationships between water quality parameters and linking those parameters to processes within an agricultural drinking water catchment. FA found that 55% of the variance in the water quality data could be explained by the first factor, which was dominated by parameters usually associated with erosion. Inclusion of pathogenic indicators in an additional FA showed that Enterococcus and Clostridium perfringens (C. perfringens) were also related to the erosion factor. Analysis of the EMCs found that most parameters were significantly higher during periods of rainfall runoff. This study shows that the most dominant processes in an agricultural catchment are surface runoff and erosion. It also shows that it is these processes which mobilise pathogenic indicators and are therefore most likely to influence the transport of pathogens. Catchment management efforts need to focus on reducing the effect of these processes on water quality.

Practitioners skilled in neonatal resuscitation and newborn care are essential to rural maternity care. 10. Training of rural maternity health care providers should include collaborative practice as well as the necessary clinical skills and competencies. Sites must be developed and supported to train midwives, nurses, and physicians and provide them with the skills necessary for rural maternity care. Training in rural and northern settings must be supported. 11. Generalist skills in maternity care, surgery, and anaesthesia are valued and should be supported in training programs in family medicine, surgery, and anaesthesia as well as nursing and midwifery. 12. All physicians and nurses should be exposed to maternity care in their training, and basic competencies should be met. 13. Quality improvement and outcome monitoring should be integral to all maternity care systems. 14. Support must be provided for ongoing, collaborative, interprofessional, and locally provided continuing education and patient safety programs.

    This research investigated the relationship between the length of women's maternity leave and marital incompatibility, in the context of other variables including the woman's employment, her dissatisfaction with the division of household labor, and her sense of role overload. Length of leave, work hours, and family salience were associated with several forms of dissatisfaction, which in turn predicted role overload. Role overload predicted increased marital incompatibility for experienced mothers but did not for first-time mothers, for whom discrepancies between preferred and actual child care were more important. Length of maternity leave showed significant interactions with other variables, supporting the hypothesis that a short leave is a risk factor that, when combined with another risk factor, contributes to personal and marital distress.

    Little is known about the retinal cellular basis of amblyopia, which is a developmental disease characterized by impaired visual acuity. This study examined the retinal transcripts associated with experimentally induced unilateral amblyopia in rats. Surgical tarsorrhaphy of the eyelids on one side was performed in pups prior to eye opening at postnatal day 14, thereby preventing any visual experience. This condition was maintained for over 2 months, after which electroretinograms (ERGs) were recorded, the retinal ganglion cell (RGC) arrangement and number were determined using neuroanatomical tracing, the retinal transcripts were studied using microarray analysis, regulated mRNAs were confirmed with quantitative reverse-transcriptase PCR, and proteins were stained using Western blotting and immunohistochemistry. An attenuated ERG was found in eyes that were deprived of visual experience. Retrograde neuroanatomical staining disclosed a larger number of RGCs within the retina on the visually deprived side compared to the non-deprived, control side, and a multilayered distribution of RGCs. At the retinomic level, several transcripts associated with retinal differentiation, such as fibroblast growth factor 2 (FGF-2), were either up- or downregulated. Most of the transcripts could be verified at the mRNA level. To unravel the role of a differentiation-associated protein, we tested FGF-2 in dissociated postnatal retinal cell cultures and found that FGF-2 is a potent factor triggering ganglion cell differentiation. The data suggest that visual experience shapes the postnatal retinal differentiation, whereas visual deprivation induces changes at the functional, cellular and molecular levels within the retina.

    Although embryonic stem (ES) cell-like induced pluripotent stem (iPS) cells have potential therapeutic applications in humans, they are also useful for creating genetically modified human disease models in nonhuman primates. In this study, we generated common marmoset iPS cells from fetal liver cells via the retrovirus-mediated introduction of six human transcription factors: Oct-3/4, Sox2, Klf4, c-Myc, Nanog, and Lin28. Four to five weeks after introduction, several colonies resembling marmoset ES cells were observed and picked for further expansion in ES cell medium. Eight cell lines were established, and validation analyses of the marmoset iPS cells followed. We detected the expression of ES cell-specific surface markers. Reverse transcription-PCR showed that these iPS cells expressed endogenous Oct-3/4, Sox2, Klf4, c-Myc, Nanog and Lin28 genes, whereas all of the transgenes were silenced. Karyotype analysis showed that two of three iPS cell lines retained a normal karyotype after a 2-month culture. Both embryoid body and teratoma formation showed that marmoset iPS cells had the developmental potential to give rise to differentiated derivatives of all three primary germ layers. In summary, we generated marmoset iPS cells via the transduction of six transcription factors; this provides a powerful preclinical model for studies in regenerative medicine.

    Biomedical perspectives have long dominated research on the etiology and progression of Alzheimer's disease (AD); yet these approaches do not solely explain observed variations in individual AD trajectories. More robust biopsychosocial models regard the course of AD as a dialectical interplay of neuropathological and psychosocial influences. Drawing on this broader conceptualization, we conducted an extensive review of empirical and theoretical literature on the associations of trauma, posttraumatic stress disorder (PTSD) and AD to develop a working model that conceptualizes the role of psychosocial stressors and physiological mechanisms in the onset and course of AD. The proposed model suggests two pathways. In the first, previous life trauma acts as a risk factor for later-life onset of AD, either directly or mediated by PTSD or PTSD correlates. In the second, de novo AD experiential trauma is associated with accelerated cognitive decline, either directly or mediated through PTSD or PTSD correlates. Evidence synthesized in this paper indicates that previous life trauma and PTSD are strong candidates as psychosocial risk factors for AD and warrant further empirical scrutiny. Psychosocial and neurological-based intervention implications are discussed. A biopsychosocial approach has the capacity to enhance understanding of individual AD trajectories, moving the field toward 'person-centered' models of care.

  7. Maternity Leave Policies

    Abstract Over recent years many European Union countries have made changes to the design of the maternity leave provision. These policy developments reflect calls for greater gender equality in the workforce and more equal share of childcare responsibilities. However, while research shows that long period of leave can have negative effects on women's labour market attachment and career advancements, early return to work can be seen as a factor preventing exclusive breastfeeding, and therefore, potentially having negative health impacts for babies. Indeed, the World Health Organisation recommends exclusive breastfeeding up to 6 months of age to provide babies with the nutrition for healthy growth and brain development, protection from life-threatening ailments, obesity and non-communicable diseases such as asthma and diabetes. Therefore, labour market demands on women may be at odds with the health benefits for children gained by longer periods of maternity leave. The aim of this article is to examine the relationship between leave provision and health benefits for children. We examine maternity and parental leave provision across European countries and its potential impact on the breastfeeding of very young babies (up to 6-months of age). We also consider economic factors of potential extension of maternity leave provision to 6 months, such as costs to businesses, effects on the female labour market attachment, and wider consequences (benefits and costs) for individuals, families, employers and the wider society.

    Full Text Available BACKGROUND: Critical incident audit and feedback are recommended interventions to improve the quality of obstetric care. To evaluate the effect of audit at district level in Thyolo, Malawi, we assessed the incidence of facility-based severe maternal complications (severe acute maternal morbidity (SAMM and maternal mortality during two years of audit and feedback. METHODOLOGY/PRINCIPAL FINDINGS: Between September 2007 and September 2009, we included all cases of maternal mortality and SAMM that occurred in Thyolo District Hospital, the main referral facility in the area, using validated disease-specific criteria. During two- to three-weekly audit sessions, health workers and managers identified substandard care factors. Resulting recommendations were implemented and followed up. Feedback was given during subsequent sessions. A linear regression analysis was performed on facility-based severe maternal complications. During the two-year study period, 386 women were included: 46 died and 340 sustained SAMM, giving a case fatality rate of 11.9%. Forty-five cases out of the 386 inclusions were audited in plenary with hospital staff. There was a reduction of 3.1 women with severe maternal complications per 1000 deliveries in the district health facilities, from 13.5 per 1000 deliveries in the beginning to 10.4 per 1000 deliveries at the end of the study period. The incidence of uterine rupture and major obstetric hemorrhage reduced considerably (from 3.5 to 0.2 and from 5.9 to 2.6 per 1000 facility deliveries respectively. CONCLUSIONS: Our findings indicate that audit and feedback have the potential to reduce serious maternal complications including maternal mortality. Complications like major hemorrhage and uterine rupture that require relatively straightforward intrapartum emergency management are easier to reduce than those which require uptake of improved antenatal care (eclampsia or timely intravenous medication or HIV-treatment (peripartum

    We examined maternal competition, an unexplored form of competition between women. Given women's high investment in offspring and mothers' key role in shaping their reproductive, social, and cultural success as adults, we might expect to see maternal competition between women as well as mate competition. Predictions about the effect of maternal characteristics (age, relationship status, educational background, number of children, investment in the mothering role) and child variables (age, sex) were drawn from evolutionary theory and sociological research. Mothers of primary school children (in two samples: N = 210 and 169) completed a series of questionnaires. A novel nine-item measure of maternal competitive behavior (MCQ) and two subscales assessing Covert (MCQ-C) and Face-to-Face (MCQ-FF) forms of competition were developed using confirmatory factor analysis. Competitiveness (MCQ score) was predicted by maternal investment, single motherhood, fewer children, and (marginally) child's older age. The effect of single motherhood (but not other predictors) was partially mediated by greater maternal investment. In response to a scenario of their child underperforming relative to their peers, a mother's competitive distress was a positive function of the importance she ascribed to their success and her estimation of her child's ability. Her competitive distress was highly correlated with the distress she attributed to a female friend, hinting at bidirectional dyadic effects. Qualitative responses indicated that nonspecific bragging and boasting about academic achievements were the most common irritants. Although 40% of women were angered or annoyed by such comments, less than 5% endorsed a direct hostile response. Instead, competitive mothers were conversationally shunned and rejected as friends. We suggest that the interdependence of mothers based on reciprocal childcare has supported a culture of egalitarianism that is violated by explicit competitiveness.

    The Askaryan effect describes coherent electromagnetic radiation from high-energy cascades in dense media with a collective charge. We present an analytic model of Askaryan radiation that accounts simultaneously for the three-dimensional form factor of the cascade, and quantum mechanical cascade elongation via the Landau-Pomeranchuk-Migdal effect. These calculations, and the associated open-source code, allow the user to avoid computationally intensive Monte Carlo cascade simulations. Searches for cosmogenic neutrinos in Askaryan-based detectors benefit from computational speed, because scans of Askaryan parameter-space are required to match neutrino signals. The Askaryan field is derived from cascade equations verified with Geant4 simulations, and compared with prior numerical and semi-analytic calculations. Finally, instructive cases of the model are transformed from the Fourier domain to the time-domain. Next-generation in situ detectors like ARA and ARIANNA can use analytic time-domain signal models to search for correlations with event candidates.

    This analysis aims to examine factors associated with delayed initiation and non-exclusive breastfeeding in Indonesia. Data were derived from the 2002/2003 and 2007 Indonesia Demographic and Health Survey. Information from 12,191 singleton live-born infants aged 0-23 months was used to examine factors associated with delayed initiation of breastfeeding. Furthermore, information from 3,187 singleton live-born infants aged 0-5 months was used to identify factors associated with non-exclusive breastfeeding. Associations between potential predictors and study outcomes were examined using logistic regression. Our study found that infants from high household wealth-index had significantly increased odds of both delayed initiation and non-exclusive breastfeeding. Other factors associated with an increased odds of delayed initiation of breastfeeding included infants from Sumatera region (OR=1.64, 95% CI: 1.38-1.95), Caesarean-section deliveries (OR=1.84, 95% CI: 1.39-2.44) and deliveries in government-owned (OR=1.38, 95% CI: 1.08-1.76) and non-health facility (OR=1.20, 95% CI: 1.00-1.43). Other factors associated with an increased odds for non-exclusive breastfeeding included parents who were in the workforce (OR=1.37, 95% CI: 1.06-1.78) and mothers with obstetric complication at childbirth (OR=1.35, 95% CI: 1.05-1.74). However, the odds reduced for infants from Eastern Indonesia (OR=0.64, 95% CI: 0.49-0.85). Poor breastfeeding practices are associated with environmental, socio-economic, pregnancy-birthing characteristics and maternal health services factors. Efforts to promote breastfeeding practices should be conducted comprehensively to target population at risk for poor breastfeeding practices.

METHODS: A retrospective study of hospital record to study maternal mortality and its causes over 3 years from January 2010 to December 2012. RESULTS: There were a total of 58 maternal deaths out of 2823 live births giving a maternal mortality ratio of 2054.55 per one lakh live births. Unbooked and late referrals account for 77.58% of maternal deaths. The majority of deaths around 75.86% were in 20-30 years age group. Haemorrhage was the commonest causes of death (24.12% followed by sepsis (18.96% and pregnancy induced hypertension 15.51% Anemia contributed to the most common indirect cause of maternal morality. CONCLUSION: Haemorrhage, sepsis and pregnancy induced hypertension including eclampsia were the direct major causes of death. Anaemia and cardiac diseases were other indirect causes of death.

  14. Growth curve analyses of the relationship between early maternal age and children's mathematics and reading performance.

    2015-03-01

    Regarding the methods used to examine the early maternal age-child academic outcomes relationship, the extant literature has tended to examine change using statistical analyses that fail to appreciate that individuals vary in their rates of growth. Of the one study I have been able to find that employs a true growth model to estimate this relationship, the authors only controlled for characteristics of the maternal household after family formation; confounding background factors of mothers that might select them into early childbearing, a possible source of bias, were ignored. The authors' findings nonetheless suggested an inverse relationship between early maternal age, i.e., a first birth between the ages of 13 and 17, and Canadian adolescents' mean math performance at age 10. Early maternal age was not related to the linear slope of age. To elucidate whether the early maternal age-child academic outcomes association, treated in a growth context, is consistent with this finding, the present study built on it using US data and explored children's mathematics and reading trajectories from age 5 on. Its unique contribution is that it further explicitly controlled for maternal background factors and employed a three-level growth model with repeated measures of children nested within their mothers. Though the strength of the relationship varied between mean initial academic performance and mean academic growth, results confirmed that early maternal age was negatively related to children's mathematics and reading achievement, net of post-teen first birth child-specific and maternal household factors. Once maternal background factors were included, there was no statistically significant relationship between early maternal age and either children's mean initial mathematics and reading scores or their mean mathematics and reading growth.

    2014-01-01

    Teamwork and collaboration have been recognized as essential competencies for health care providers in the field of maternity care. Health care policy and regulatory bodies have stressed the importance of Interprofessional Education (IPE) for learners in this field; however, there is little evidence of sustained application of pre-qualifying IPE to the realm of interprofessional collaboration (IPC) in practice following qualification. The aim of this research was to understand how newly qualified midwives applied their IPE training to professional practice. A purposive sample of midwifery students, educators, new midwives and Heads of Midwifery from four universities in the United Kingdom participated in semi-structured interviews, questionnaires and focus groups. Qualitative, grounded theory methodology was used to develop the emerging theory. Newly qualified midwives appeared better able to integrate their IPE training into practice when IPE occurred in a favourable learning environment that facilitated acquisition and application of IPE skills and that recognized the importance of shared partnership between the university and the clinical workplace.

  18. Evolution of maternal effect senescence.

    Moorad, Jacob A; Nussey, Daniel H

    2016-01-12

    Increased maternal age at reproduction is often associated with decreased offspring performance in numerous species of plants and animals (including humans). Current evolutionary theory considers such maternal effect senescence as part of a unified process of reproductive senescence, which is under identical age-specific selective pressures to fertility. We offer a novel theoretical perspective by combining William Hamilton's evolutionary model for aging with a quantitative genetic model of indirect genetic effects. We demonstrate that fertility and maternal effect senescence are likely to experience different patterns of age-specific selection and thus can evolve to take divergent forms. Applied to neonatal survival, we find that selection for maternal effects is the product of age-specific fertility and Hamilton's age-specific force of selection for fertility. Population genetic models show that senescence for these maternal effects can evolve in the absence of reproductive or actuarial senescence; this implies that maternal effect aging is a fundamentally distinct demographic manifestation of the evolution of aging. However, brief periods of increasingly beneficial maternal effects can evolve when fertility increases with age faster than cumulative survival declines. This is most likely to occur early in life. Our integration of theory provides a general framework with which to model, measure, and compare the evolutionary determinants of the social manifestations of aging. Extension of our maternal effects model to other ecological and social contexts could provide important insights into the drivers of the astonishing diversity of lifespans and aging patterns observed among species.

    Prana is the energy, when the self-energizing force embraces the body with extension and expansion and control, it is pranayama. It may affect the milieu at the bronchioles and the alveoli particularly at the alveolo-capillary membrane to facilitate diffusion and transport of gases. It may also increase oxygenation at tissue level. Aim of our study is to compare pulmonary functions and diffusion capacity in patients of bronchial asthma before and after yogic intervention of 2 months. Sixty stable asthmatic-patients were randomized into two groups i.e group 1 (Yoga training group) and group 2 (control group). Each group included thirty patients. Lung functions were recorded on all patients at baseline, and then after two months. Group 1 subjects showed a statistically significant improvement (Pyoga practice. Quality of life also increased significantly. It was concluded that pranayama & yoga breathing and stretching postures are used to increase respiratory stamina, relax the chest muscles, expand the lungs, raise energy levels, and calm the body.

    Obesity is associated with increased inflammation which represents a link to atherosclerosis and cardiovascular disease. Lipoprotein associated phospholipase A2 (Lp-PLA2) is an independent marker of inflammation and atherosclerosis risk. To assess the impact of weight loss on metabolic markers of atherosclerosis including Lp-PLA2 we examined a group of Czech non-diabetic obese/overweight children exposed to a lifestyle intervention. Fourty unrelated overweight/obese non-diabetic Czech children (13.7 ± 2.1 years, average BMI at baseline 29.8 ± 2.6 kg/m2) underwent 4 weeks of lifestyle modification (reduction of energy intake to age matched optimum and supervised physical activity). Anthropometrical and biochemical variables were determined at baseline and after the intervention. Lp-PLA2 mass concentration was assessed using the ELISA kit. Wilcocson's rank test and Spearman's correlation were used for statistical analysis. A significant decrease of BMI and waist circumference was associated with significant changes of plasma lipoprotein and glycaemia levels. Mass concentration of Lp-PLA2 at the baseline was 402 ± 94 μg/ml, after the intervention 368 ± 105 μg/ml (p=0.008). Change in Lp-PLA2 was associated with triglyceride level decrease (p=0.009). Intensive lifestyle modification leading to body weight decrease results in significant changes of plasma lipoprotein levels and, also, a drop of Lp-PLA2 levels in paediatric obese patients. However, even after the intervention Lp-PLA2 concentrations in this patient group remain elevated suggesting possible increased atherosclerosis risk in later life. © 2011 Neuroendocrinology Letters

    Full Text Available Phenylketonuria is a hereditary metabolic disorder inherited in an autosomal recessive pattern. Elevated phenylalanine levels in a pregnant woman with phenylketonuria result in phenylalanine embryopathy. Failure to follow special diets during gestation results in neonatal dysplasia. More favorable outcomes are observed when phenylalanine levels remain within normal ranges prior to conception, or at least when they reach normal levels by the 4th-10th weeks of gestation. We report the case of a newborn with maternal phenylketonuria.

    This study uses data from the nationally representative Early Childhood Longitudinal Study-Birth Cohort to examine the relationship between maternal depression, maternal sensitivity, and child attachment, specifically among Hispanic and Asian American mothers and their young children, and to explore the role of cultural variation and nativity in the associations between these variables. Data used in this study were collected from biological mothers on two occasions, when their children were approximately 9 and 24 months of age. Trained observers completed a direct assessment of child attachment security and an observational measure of maternal sensitivity, data on maternal depression was obtained via maternal report. Hierarchical logistic regression models were used to predict odds of child insecure attachment. The risk of child insecure attachment associated with chronic maternal depression was found to be much higher for Hispanic mothers than for Asians. In contrast, mothers' foreign-born status was a stronger risk factor than depression for insecure child attachment among Asian Americans. Maternal sensitivity significantly reduced the odds of Asian American children being insecurely attached by more than half. Among the full sample of mothers, which included U.S.-born non-Hispanic White mothers and U.S.-born non-Hispanic Black mothers, decreased maternal sensitivity mediated the association between chronic depression and child insecure attachment. However, this mediation was not found in stratified analyses of Hispanic and Asian mothers. Finally, mothers' nativity did not influence the extent to which maternal depression or sensitivity was associated with child attachment. These findings suggest that the associations between maternal depression, sensitivity, and child attachment are culturally specific, and that mothers' immigrant status may be a risk factor in some racial/ethnic groups but protective in others.

    Full Text Available Abstract Background Maternal smoking is a risk factor for pediatric lung disease, including asthma. Animal models suggest that maternal smoking causes defective alveolarization in the offspring. Retinoic acid signaling modulates both lung development and postnatal immune function. Thus, abnormalities in this pathway could mediate maternal smoking effects. We tested whether maternal smoking disrupts retinoic acid pathway expression and functioning in a murine model. Methods Female C57Bl/6 mice with/without mainstream cigarette smoke exposure (3 research cigarettes a day, 5 days a week were mated to nonsmoking males. Cigarette smoke exposure continued throughout the pregnancy and after parturition. Lung tissue from the offspring was examined by mean linear intercept analysis and by quantitative PCR. Cell culture experiments using the type II cell-like cell line, A549, tested whether lipid-soluble cigarette smoke components affected binding and activation of retinoic acid response elements in vitro. Results Compared to tobacco-naïve mice, juvenile mice with tobacco toxin exposure had significantly (P  Conclusions A murine model of maternal cigarette smoking causes abnormal alveolarization in association with altered retinoic acid pathway element expression in the offspring. An in vitro cell culture model shows that lipid-soluble components of cigarette smoke decrease retinoic acid response element activation. It is feasible that disruption of retinoic acid signaling contributes to the pediatric lung dysfunction caused by maternal smoking.

    This study models various pathways linking maternal education and child nutritional status in Bolivia, using a national sample of children. Pathways examined include socioeconomic status, health knowledge, modern attitudes towards health care, female autonomy, and reproductive behavior. The data come from the 1998 Bolivia Demographic and Health Survey. Logistic regression results suggest that socioeconomic factors are the most important pathways linking maternal education and child nutritional status, and that modern attitudes about health care also explain the impact of education. Health care knowledge accounts for less of the effect of maternal education on child nutritional status, with autonomy being the weakest pathway. Other pathways, such as reproductive behaviors, appear to influence nutritional status independent of maternal education. Overall, the pathways examined accounted for 60 percent of the effect of maternal education on child nutritional status.

    Full Text Available BACKGROUND: Child neglect is the most common form of child maltreatment, yet the biological basis of maternal neglect is poorly understood and a rodent model is lacking. METHODOLOGY/PRINCIPAL FINDINGS: The current study characterizes a population of mice (MaD1 which naturally exhibit maternal neglect (little or no care of offspring at an average rate of 17% per generation. We identified a set of risk factors that can predict future neglect of offspring, including decreased self-grooming and elevated activity. At the time of neglect, neglectful mothers swam significantly more in a forced swim test relative to nurturing mothers. Cross-fostered offspring raised by neglectful mothers in turn exhibit increased expression of risk factors for maternal neglect and decreased maternal care as adults, suggestive of possible epigenetic contributions to neglect. Unexpectedly, offspring from neglectful mothers elicited maternal neglect from cross-fostered nurturing mothers, suggesting that factors regulating neglect are not solely within the mother. To identify a neurological pathway underlying maternal neglect, we examined brain activity in neglectful and nurturing mice. c-Fos expression was significantly elevated in neglectful relative to nurturing mothers in the CNS, particularly within dopamine associated areas, such as the zona incerta (ZI, ventral tegmental area (VTA, and nucleus accumbens. Phosphorylated tyrosine hydroxylase (a marker for dopamine production was significantly elevated in ZI and higher in VTA (although not significantly in neglectful mice. Tyrosine hydroxylase levels were unaltered, suggesting a dysregulation of dopamine activity rather than cell number. Phosphorylation of DARPP-32, a marker for dopamine D1-like receptor activation, was elevated within nucleus accumbens and caudate-putamen in neglectful versus nurturing dams. CONCLUSIONS/SIGNIFICANCE: These findings suggest that atypical dopamine activity within the maternal brain

    There is increasing evidence that human pregnancy outcome can be significantly compromised by suboptimal maternal nutritional status. Poor diet results in a maternal-fetal environment in which the teratogenicity of other insults such as alcohol might be amplified. As an example, there is evidence that zinc (Zn) can interact with maternal alcohol exposure to influence the risk for fetal alcohol spectrum disorders (FASD). Studies with experimental animals have shown that the teratogenicity of a...

    The attempt was made to determine the factors responsible for the maternal deaths in the government hospitals of West Malaysia over the 1967-1969 period. The study covered all maternal deaths in the government hospitals during this 2-year period. Despite an increase in the number of deliveries in government hospitals from 83,654 in 1964 to 92,583 in 1969, the maternal mortality had declined from 27/10,000 to 22/10,000. The maternal mortality rate in government hospitals was higher than the national maternal mortality rate because of the practice of referring all abnormal obstetric cases to hospitals for management. Hemorrhage continued as the primary cause of maternal deaths with toxemia as the 2nd important cause and infection as the 3rd. In the rural areas midwives found postpartum hemorrhage a major problem because of the coexistence of anemia in pregnancy. Other complications of pregnancy, childbirth and puerperium included obstructed and neglected labors due to cephalo-pelvic disproportion, abnormal lie, and presentation and ruptured uterus referred from the rural areas to the hospitals. Hypertension was the most important cause in the associated maternal diseases. The following are included among the steps taken by the government to reduce maternal mortality: 1) development of an excellent infrastructure of health units; 2) a training program for midwives; and 3) a plan to integrate the family planning services with the health services.

    2010-01-01

    Full Text Available Background/Aim. Low birth weight (LBW is a result of preterm birth or intrauterine growth retardation, and in both cases is the strongest single factor associated with perinatal and neonatal mortality. It is considered that socioeconomic factors, as well as mothers bad habits, play the most significant role in the development of LBW, which explains notable number of researches focused on this particular problem. The aim of this study was to characterize socioeconomic factors, as well as smoking habits of the mothers, and their connection with LBW. Methods. The questionnaire was carried out among mothers of 2 years old children (n = 956, born after 37 gestational weeks. The characteristics of mothers who had children with LBW, defined as < 2 500 g, (n = 50, were matched with the characteristics of mothers who had children ≥ 2 500 g, (n = 906. For defining risk factors, and protective factors as well, we used univariant and multivariant logistic modeles. Results. As significant risk factors for LBW in an univariant model we had education level of the mothers, smoking during pregnancy, smoking before pregnancy, the number of daily cigarettes, the number of cigarettes used during pregnancy, paternal earnings and socioeconomic factors. In a multivariant model the most significant factors were socioeconomic factors, education level of the mothers, paternal earnings and mothers smoking during pregnancy. Conclusion. Smoking during pregnancy and socioeconomic factors have great influence on LBW. Future studies should be carried out in different social groups, with the intention to define their influence on LBW and reproduction, as well. This should be the proper way of adequate health breeding planning for giving up smoking, the prevention of bad habits and melioration of mothers and children health, as the most vulnerable population.

    Full Text Available BACKGROUND: Coupled with the largest number of maternal deaths, adolescent pregnancy in India has received paramount importance due to early age at marriage and low contraceptive use. The factors associated with the utilization of maternal healthcare services among married adolescents in rural India are poorly discussed. METHODOLOGY/PRINCIPAL FINDINGS: Using the data from third wave of National Family Health Survey (2005-06, available in public domain for the use by researchers, this paper examines the factors associated with the utilization of maternal healthcare services among married adolescent women (aged 15-19 years in rural India. Three components of maternal healthcare service utilization were measured: full antenatal care, safe delivery, and postnatal care within 42 days of delivery for the women who gave births in the last five years preceding the survey. Considering the framework on causes of maternal mortality proposed by Thaddeus and Maine (1994, selected socioeconomic, demographic, and cultural factors influencing outcome events were included as the predictor variables. Bi-variate analyses including chi-square test to determine the difference in proportion, and logistic regression to understand the net effect of predictor variables on selected outcomes were applied. Findings indicate the significant differences in the use of selected maternal healthcare utilization by educational attainment, economic status and region of residence. Muslim women, and women belonged to Scheduled Castes, Scheduled Tribes, and Other Backward Classes are less likely to avail safe delivery services. Additionally, adolescent women from the southern region utilizing the highest maternal healthcare services than the other regions. CONCLUSIONS: The present study documents several socioeconomic and cultural factors affecting the utilization of maternal healthcare services among rural adolescent women in India. The ongoing healthcare programs should start

    We sought to examine the relationship between maternal markers of inflammation and labor performance. A nested cohort study was performed utilizing an established cohort of term nulliparous patients. Maternal blood was collected at the onset of regular, painful contractions in patients undergoing labor induction or at admission in patients with spontaneous labor. Levels of cytokines including interleukin (IL)-1, IL-6, and tumor necrosis factor-α were determined using standard multiplex methodology. Maternal demographic data were collected prospectively. Detailed retrospective chart review was performed to extract data on cervical dilation, effacement, and station during labor. Subjects were excluded if they failed to achieve complete dilation. Mixed effects modeling was used to examine the association between serum cytokine quartiles and labor progress in the latent and active phases. In all, 334 women were included in our analysis. The lowest quartile of IL-6 was associated with slower latent labor (P = .001). In contrast, the highest quartiles of IL-1 and tumor necrosis factor-α were associated with slower active labor (P = .03 and .0002, respectively). Proinflammatory activation is important in labor initiation. However, once active labor is established, excess inflammation can be detrimental to efficient labor progress. These data may explain, in part, the known associations among clinical chorioamnionitis, cesarean delivery, and postpartum hemorrhage. Copyright © 2014 Mosby, Inc. All rights reserved.

    Full Text Available Abstract Background Risk factors for postnatal depression (PND are under-explored in the Chinese populations. There is increasing recognition of the importance of identifying predictive factors during the antenatal period for PND. The present study aimed to identify the risk factors for postnatal depression in a community cohort of Chinese women with special focus on the antenatal risk factors. Methods Eight hundred and five Chinese women were interviewed during their third trimester of pregnancy and at around 2 months postnatally. Putative risk factors for PND were collected and the diagnosis of PND was confirmed by the Structured Clinical Interview for DSM-IV Axis I Disorders. The 2-month postnatal depression status was used as the dependent variable for univariate and multivariate analyses against putative risk factors. Results Marital dissatisfaction (Relative Risk = 8.27, dissatisfied relationship with mother-in-law (Relative Risk = 3.93, antenatal depressive symptomatology (Relative Risk = 3.90, and anxiety-prone personality (Relative Risk = 2.14 predicted PND in Chinese women independently. Conclusions Chinese women tend to keep their own feelings and emotions and it is important to monitor Chinese pregnant women with these predictive risk factors so that PND can be identified early.

    The consequences of exposure to prenatal maternal anxiety for the development of child temperament were examined in a sample of 120 healthy, 2-year-old children. Prenatal maternal state and pregnancy-specific anxiety (PSA) were measured five times during pregnancy, and maternal state anxiety was measured again at 2 years post partum. Child temperament was measured at 2 years using the Early Childhood Behavior Questionnaire. The relationship between the trajectory of maternal anxiety across gestation and negative affectivity was evaluated using hierarchical linear growth curve modeling. Higher maternal PSA between 13 and 17 weeks of gestation was associated with increased negative temperament in the children. This association could not be explained by postnatal maternal anxiety, demographic, or obstetric factors. Prenatal maternal state anxiety was not associated with child temperament. These findings demonstrate that PSA early in gestation has a distinctive influence on the developing fetus.

    Projection of current trends in maternal and neonatal mortality reduction shows that many countries will fall short of the UN Millennium Development Goal 4 and 5. Underutilization of maternal health services contributes to this poor progress toward reducing maternal and neonatal morbidity and mortality. Moreover, the quality of services continues to lag in many countries, with a negative effect on the health of women and their babies, including deterring women from seeking care. To enhance the use and provision of quality maternal care, countries and donors are increasingly using financial incentives. This paper introduces the JHPN Supplement, in which each paper reviews the evidence of the effectiveness of a specific financial incentive instrument with the aim of improving the use and quality of maternal healthcare and impact. The US Agency for International Development and the US National Institutes of Health convened a US Government Evidence Summit on Enhancing Provision and Use of Maternal Health Services through Financial Incentives on 24-25 April 2012 in Washington, DC. The Summit brought together leading global experts in finance, maternal health, and health systems from governments, academia, development organizations, and foundations to assess the evidence on whether financial incentives significantly and substantially increase provision, use and quality of maternal health services, and the contextual factors that impact the effectiveness of these incentives. Evidence review teams evaluated the multidisciplinary evidence of various financial mechanisms, including supply-side incentives (e.g. performance-based financing, user fees, and various insurance mechanisms) and demand-side incentives (e.g. conditional cash transfers, vouchers, user fee exemptions, and subsidies for care-seeking). At the Summit, the teams presented a synthesis of evidence and initial recommendations on practice, policy, and research for discussion. The Summit enabled structured

    Full Text Available Abstract Background Death of an infant in utero or at birth has always been a devastating experience for the mother and of concern in clinical practice. Infant mortality remains a challenge in the care of pregnant women worldwide, but particularly for developing countries and the need to understand contributory factors is crucial for addressing appropriate perinatal health. Methods Using information available in obstetric records for all deliveries (17,072 births at Harare Maternity Hospital, Zimbabwe, we conducted a cross-sectional retrospective analysis of a one-year data, (1997–1998 to assess demographic and obstetric risk factors for stillbirth and early neonatal death. We estimated risk of stillbirth and early neonatal death for each potential risk factor. Results The annual frequency of stillbirth was 56 per 1,000 total births. Women delivering stillbirths and early neonatal deaths were less likely to receive prenatal care (adjusted relative risk [RR] = 2.54; 95% confidence intervals [CI] 2.19–2.94 and RR = 2.52; 95% CI 1.63–3.91, which for combined stillbirths and early neonatal deaths increased with increasing gestational age (Hazard Ratio [HR] = 3.98, HR = 7.49 at 28 and 40 weeks of gestation, respectively. Rural residence was associated with risk of infant dying in utero, (RR = 1.33; 95% CI 1.12–1.59, and the risk of death increased with increasing gestational age (HR = 1.04, HR = 1.69, at 28 and 40 weeks of gestation, respectively. Older maternal age was associated with risk of death (HR = 1.50; 95% CI 1.21–1.84. Stillbirths were less likely to be delivered by Cesarean section (RR = 0.64; 95% CI 0.51–0.79, but more likely to be delivered as breech (RR = 4.65; 95% CI 3.88–5.57, as were early neonatal deaths (RR = 3.38; 95% CI 1.64–6.96. Conclusion The frequency of stillbirth, especially macerated, is high, 27 per 1000 total births. Early prenatal care could help reduce perinatal death linking the woman to the health

    Full Text Available Infant mortality rate is a serious issue worldwide. Pakistan being a developing country comprises of diverse socioeconomic classes. Various studies have suggested some association of maternal anthropometric parameters with neonatal outcomes. The aim behind this research is to determine the impact of socioeconomic conditions on maternal health indicators and neonatal parameters in the population of Pakistan. This study included 90 pregnant females belonging to different socioeconomic conditions and were grouped according to their socioeconomic classes. Data was collected from the case histories of participants admitted in different hospitals of Karachi. The data of maternal and neonatal parameters was assessed statistically and their associations with the socioeconomic conditions were assessed. Maternal hemoglobin and maternal gravidity have shown a strong association with socioeconomic conditions with high significance (p < 0.05. However, neonatal parameters have shown diverse results among the three classes. Neonatal gestational age was found to be significant in comparison between upper versus lower (p = 0.001 and upper versus middle classes (p = 0.006, but it was insignificant in case of middle versus lower class (p = 0.88. Likewise, neonatal birth weight is significant between upper versus lower (p = 0.001 and upper versus middle classes (p = 0.019, but it was insignificant in case of middle versus lower class (p = 0.258. Neonatal apgar score is found to be significant in upper versus lower (p = 0.001 and middle versus lower classes (p = 0.001 and insignificant between middle and lower class (p = 0.125. This study concludes that socioeconomic factors play a vital role in determining the maternal health characteristics which in turn affects the neonatal outcomes. It is therefore recommended that antenatal care should be provided to all pregnant females. The whole community should work hand in hand to establish good health care centers, create

    Maternal deaths in developing countries are rooted in womens powerlessness and their unequal access to employment, finance, education, basic health care, and other resources. Nigeria is Africa's most populous country, and it is an oil producing country, but Nigeria has one of the worst maternal mortality rates in Africa. These deaths were linked to deficiencies in access to health care including poor quality of health services, socio-cultural factors, and access issues related to the poor status of women. To address these problems, a participatory approach was used to bring Christian women from various denominations in Eastern Nigeria together. With technical assistance from a research unit in a university in Eastern Nigeria, the women were able to implement a Safe Motherhood project starting from needs assessment to program evaluation. Lessons learned from this program approach are discussed.

    Full Text Available The relationship between maternal factors and the response of preterm infants to pain and stress experienced during heel puncture while in maternal kangaroo care was investigated. This descriptive study included 42 mothers and their preterm infants cared for in a neonatal unit. Data were collected in the baseline, procedure, and recovery phases. We measured the neonates' facial actions, sleep and wake states, crying, salivary cortisol levels, and heart rate, in addition to the mothers' behavior, salivary cortisol levels, and mental condition. The influence of the maternal explanatory variables on the neonatal response variables were verified through bivariate analysis, ANOVA, and multiple regression. The mothers' behavior and depression and/or anxiety did not affect the neonates' responses to pain and stress, though the mothers' levels of salivary cortisol before the procedure explained the variance in the neonates' levels of salivary cortisol after the procedure (p=0.036. Additionally, the mothers' baseline levels of salivary cortisol along with the neonates' age explained the variance in the neonates' heart rate (p=0.001. The ability of mothers to regulate their own stress contributed to the infants' responses to pain and stress.Asociación entre los factores maternos y la respuesta de los prematuros sometidos a punción del calcáneo en posición canguro.

    Understanding the overall dietary patterns of a population is a key step in initiating appropriate nutritional interventions and policies. Studies characterising the dietary patterns of Nigerian mothers and children are lacking. Complete dietary data for 13,566 mothers and their 13,506 children were analysed from the 2008 Nigerian Demographic and Health Surveys (NDHS), a nationally representative sample, to identify the overall maternal and child dietary patterns and to study the potential determinants of such dietary patterns. The 2008 NDHS included questions that inquired about the food items mothers and their children had consumed during the 24 h preceding the day of the interview. Factor analysis with the principal component procedure was used to construct the dietary patterns, and multiple multilevel logistic regression was used to investigate the determinants of the dietary patterns. Four ('mixed', 'traditional', 'staple foods and milk products' and 'beverages') and five ('mixed', 'selective', 'beverages and candies', 'gruels, grains and semi-solids' and 'infant formula and cereals') distinct dietary patterns were obtained for the mothers and children, respectively. The key determinants of both maternal and child dietary patterns were month of interview, religion, region of residence, maternal education, maternal occupation, wealth index and maternal body mass index. Marital status additionally predicted maternal patterns, while sex of the child, number of siblings, child's age, maternal age and place of residence additionally determined the child's patterns. This study has identified four and five different dietary patterns to characterise the dietary habits of Nigerian mothers and their children, respectively, and has shown the important socio-economic/demographic factors influencing the dietary patterns, which can guide appropriate nutritional interventions among Nigerian mothers and children. © 2012 Blackwell Publishing Ltd.

    Data were obtained from three samples of women of childbearing age. One sample of women is from prenatal clinics serving Plains Indian women. The second sample is of women from the Plains whose children were referred to special diagnostic developmental clinics, as their children were believed to have developmental issues consistent with prenatal alcohol consumption. The third sample is of women from South Africa, each of whom has given birth to a child diagnosed with full fetal alcohol syndrome (FAS). Data across samples conform to expected trends on many variables. For example, the maternal age at time of pregnancy, a major risk factor for FAS, ranged from a mean of 23.5 years for the prenatal clinic sample, to 23.8 years for the developmental clinic sample, to 27.6 for the sample of women who have delivered children with FAS. Other variables of maternal risk for FAS expected from the extant literature, such as high gravidity and parity, binge drinking, heavy intergenerational drinking in the mother's extended family and immediate social network, and length of drinking career, were compared across the three samples with variable results. However, normative measures of drinking problems are unreliable when reported across cultures. An unexpected finding from this three-sample comparison was the differential risk found when comparing U.S. women to South African women. Women in the U.S. Plains Indian samples report a high consumption of alcohol in a binge pattern of drinking, yet there is less detectable damage to the fetus than among the South African women. Body mass index (BMI) and lifelong and current nutrition may have a substantial impact, along with the above factors, in relative risk for an FAS birth. The level of risk for producing a child with FAS is influenced by environmental and behavioral conditions that vary between populations and among individual women. Also, because many syndromes are genetically based, there is a need for full behavioral and

    Assessment of severe maternal morbidity using World Health Organization (WHO) 'near-miss' criteria is gaining in importance as a valuable tool in the assessment of maternity care of women. Identification of cases allows an understanding of aetiology of severe morbidity and factors contributing to poor maternal outcomes. The aim of this study is to determine the rate of maternal 'near miss' at Royal Darwin Hospital (RDH) and the utility of the WHO near-miss criteria as a tool for data collection in a regional Australian context. Cases of maternal 'near miss' and deaths were prospectively identified over a period of 12 months using the WHO criteria. During the audit period, there were 2080 live births at Royal Darwin Hospital (RDH): 10 women presented with a 'near miss' and there was one maternal death. The maternal mortality ratio for the hospital was 48/100 000 live births, the maternal 'near-miss' index ratio was 4.8/1000 live births, and the combination of maternal deaths and near misses gave a severe maternal outcome (SMO) ratio of 5.3/1000 live births. The main cause of obstetric 'near miss' was obstetric haemorrhage. Indigenous women and women from remote areas comprised a significant portion of 'near-miss' cases. The rates of maternal 'near miss' at RDH are consistent with other studies in the developed world. The WHO maternal 'near-miss' audit tool helps health professionals understand and anticipate severe maternal morbidities, with the aim of improving maternal and perinatal outcomes. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Paralleling the global epidemic of obesity figures in the general population, the incidence of maternal obesity (BMI >30 kg/m2 at the start of pregnancy) has been rising over the last world. While most European countries do not systematically report obesity figures in their pregnant population......, the prevalence of maternal obesity varies from 7 to 25% and seems strongly related to social and educational inequalities. Obesity during pregnancy represents an important preventable risk factor for adverse pregnancy outcomes and is associated with negative long-term health outcomes for both mothers...... and offspring. These effects are often aggravated by the high incidence of abnormal glucose tolerance and excessive gestational weight gain found in this group. The main controversies around the management of the obese pregnant women are related to (1) the value of repeated weighing during pregnancy, (2...

    Summary BACKGROUND Corticotropin-releasing hormone (CRH) in maternal blood originates primarily from gestational tissues and elevated levels in midpregnancy have been linked to adverse pregnancy outcomes. Investigators have hypothesized that high levels of maternal stress might lead to elevated CRH levels in pregnancy. Yet a few studies have measured maternal CRH levels among subgroups of women who experience disproportionate socioeconomic disadvantage, such as African-American and Hispanic women, and found that these groups have lower CRH levels in pregnancy. Our goal was to identify maternal characteristics related to CRH levels in midpregnancy and examine which if any of these factors help to explain race differences in CRH levels. METHODS The Pregnancy Outcomes and Community Health (POUCH) Study prospectively enrolled women at 15–27 weeks’ gestation from 52 clinics in five Michigan communities (1998–2004). Data from the POUCH Study were used to examine maternal demographics, anthropometrics, health behaviors, and psychosocial factors (independent variables) in relation to midpregnancy blood CRH levels modeled as log CRH pg/ml (dependent variable). Analyses were conducted within a subcohort from the POUCH Study (671 non-Hispanic Whites, 545 African Americans) and repeated in the subcohort subset with uncomplicated pregnancies (n=746). Blood levels of CRH and independent variables were ascertained at the time of enrollment. All regression models included week of enrollment as a covariate. In addition, final multivariable regression models alternately incorporated different psychosocial measures along with maternal demographics and weight. Psychosocial variables included measures of current depressive symptoms, perceived stress, coping style, hostility, mastery, anomie, and a chronic stressor (history of abuse as a child and adult). RESULTS In subcohort models, the adjusted mean CRH level was significantly lower in African Americans vs. non-Hispanic whites

    Abstract Since the evidence regarding the association between maternal hepatitis C virus (HCV) infection and impaired intrauterine fetal growth had not been conclusive, the aim of the present study was to evaluate the risk of maternal HCV infection in association with intrauterine fetal growth restriction (IUGR) and/or low birth weight infants (LBW). We performed an extensive literature search of PubMed, MEDLINE, and EMBASE through December 1, 2015. The odds ratios (ORs) of HCV infection and IUGR/LBW were calculated and reported with 95% confidence intervals (95% CIs). Statistical analysis was performed using RevMen 5.3 and Stata 10.0. Seven studies involving 4,185,414 participants and 5094 HCV infection cases were included. Significant associations between HCV infection and IUGR (OR = 1.53, 95% CI: 1.40–1.68, fixed effect model) as well as LBW were observed (OR = 1.97, 95% CI: 1.43–2.71, random effect model). The results still indicated consistencies after adjusting for multiple risk factors which could affect fetal growth, including maternal age, parity, maternal smoking, alcohol abuse, drugs abuse, coinfected with HBV/HIV and preeclampsia. Our findings suggested that maternal HCV infection was significantly associated with an increased risk of impaired intrauterine fetal growth. In clinical practice, a closer monitoring of intrauterine fetal growth by a series of ultrasound might be necessary for HCV-infected pregnant population. PMID:27583932

    Dendritic cells (DCs) can acquire immunogenic or tolerogenic properties depending on intrinsic and tissue environmental factors. We aimed to determine the immunomodulatory effects of decidual soluble factors from abortion- and non-abortion-prone mice on DC functions. The decidual cell supernatants (DS) were obtained from abortion-prone and non-abortion-prone mice. Splenic DCs were treated with DS and conalbumin (as an antigen) and injected into the palms of the mice. After five days, regional lymph node cells were collected and cultured in the presence and absence of conalbumin. The proliferation of lymphocyte cells, the frequency of regulatory T cells (Tregs), and the production of IL-4 and IFN-γ were measured by [(3)H]thymidine incorporation, flow cytometry, and ELISA respectively. Our results indicated that DS from both abortion- and non-abortion-prone mice decreased the ability of DCs to induce lymphocyte proliferation and IFN-γ production, while enhanced their capacity to induce Tregs compared with non-treated DCs. Another important finding was that the immunosuppressive effects of DS from abortion-prone mice on DCs for inducing proliferative responses, developing Tregs, and producing IFN-γ by primed lymphocytes was less than DS from non-abortion-prone mice. We also found that only DS from non-abortion-prone mice could enhance the capacity of DCs to induce IL-4 production by primed lymphocytes. It can be concluded that decidua-secreted factors, by altering DC functions, can determine the pattern of immune responses at the fetomaternal interface and, subsequently, pregnancy outcome.

    We analysed the prevalence of the most common hereditary thrombophilia (hTP) - factor V Leiden (FVL) mutation, prothrombin 20210 G>A substitution (PT) - and the 677 C>T replacement in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene in Caucasian patients with a history of two and more consecutive recurrent miscarriages (RMs) as compared to healthy controls with an identical ethnic background and at least one live birth. A multicenter analysis of three hTP was performed in 641 RM patients identically screened at specialized university centres. The study groups consisted of 240 patients with 2 (1) and 401 patients with >2 miscarriages (2) and were compared with 157 controls. There was no significant difference in the prevalence of the hTP between RM patients and controls nor within the two study groups. Subgroup analysis showed that the homozygous MTHFR polymorphism was significantly more prevalent in the study group 2 as compared to study group 1 (13.9 versus 7.9%, P = 0.02). In Caucasians, maternal FVL or PT mutations do not seem to contribute to the pathophysiology of RM, irrespective of the number of miscarriages. However, the role of the homozygous MTHFR polymorphism merits further investigation. © 2013 John Wiley & Sons Ltd.

    Background Information tracking changes of birthweight is scarce in China. To examine trends of low birthweight (birthweight birthweight ≥ 4000 g) and potential risk factors in Beijing, hospital records from two major obstetrics and gynecology hospitals in urban districts in Beijing were analyzed. Methods Hospital records from 1996 to 2010 were retrieved. Information of prenatal examination and birth outcomes was entered into a structured database. Live births were used for trend analysis. Information of live births in 2010 was used to identify potential risk factors. Results A total of 63 661 live births were delivered during 1996–2010 in the study hospitals. The average birthweight increased from 3271 g in 1996 to 3 359 g in 2000 and slightly declined to 3 331 in 2010. The percentage of low birthweight fluctuated around 4.0%. No significant increase or decrease was observed. Preterm birth was the main cause of low birthweight, accounting for more than 73% of low birthweight. The average percentage of macrosomia was 7.6%. The percentages of macrosomia increased from 6.6% in 1996 to 9.5% in 2000 and declined to 7.0% in 2010. Excessive gestational weight gain and gestational diabetes were significantly associated with macrosomia. Conclusions Continuously monitoring abnormal birthweight is needed and intervention should focus on appropriate gestational weight gain and reduction of preterm birth and gestational diabetes.
