Whether the changing gestational age distribution in the United States since 2005 has affected perinatal mortality remains unknown. To examine changes in gestational age distribution and gestational age-specific perinatal mortality. This retrospective cohort study examined trends in US perinatal mortality by linking live birth and infant death data among more than 35 million singleton births from January 1, 2007, through December 31, 2015. Year of birth and changes in gestational age distribution. Changes in the proportion of births at gestational ages 20 to 27, 28 to 31, 32 to 33, 34 to 36, 37 to 38, 39 to 40, 41, and 42 to 44 weeks; changes in perinatal mortality (stillbirth at ≥20 weeks, and neonatal deaths at <28 days) rates; and contribution of gestational age changes to perinatal mortality. Trends were estimated from log-linear regression models adjusted for confounders. Among the 34 236 577 singleton live births during the study period, the proportion of births at all gestational ages declined, except at 39 to 40 weeks, which increased (54.5% in 2007 to 60.2% in 2015). Overall perinatal mortality declined from 9.0 to 8.6 per 1000 births (P < .001). Stillbirths declined from 5.7 to 5.6 per 1000 births (P < .001), and neonatal mortality declined from 3.3 to 3.0 per 1000 births (P < .001). Although the proportion of births at gestational ages 34 to 36, 37 to 38, and 42 to 44 weeks declined, perinatal mortality rates at these gestational ages showed annual adjusted relative increases of 1.0% (95% CI, 0.6%-1.4%), 2.3% (95% CI, 1.9%-2.8%), and 4.2% (95% CI, 1.5%-7.0%), respectively. Neonatal mortality rates at gestational ages 34 to 36 and 37 to 38 weeks showed a relative adjusted annual increase of 0.9% (95% CI, 0.2%-1.6%) and 3.1% (95% CI, 2.1%-4.1%), respectively. Although the proportion of births at gestational age 39 to 40 weeks increased, perinatal mortality showed an annual relative adjusted decline of -1.3% (95% CI, -1.8% to -0.9%). The decline in neonatal mortality rate was largely attributable to changes in the gestational age distribution than to gestational age-specific mortality. Although the proportion of births at gestational age 39 to 40 weeks increased, perinatal mortality at this gestational age declined. This finding may be owing to pregnancies delivered at 39 to 40 weeks that previously would have been unnecessarily delivered earlier, leaving fetuses at higher risk for mortality at other gestational ages.

Perinatal audit and the three-delays model are increasingly being employed to analyse barriers to perinatal health, at both community and facility level. Using these approaches, our aim was to assess factors that could contribute to perinatal mortality and potentially avoidable deaths at Rwandan hospitals. Perinatal audits were carried out at two main urban hospitals, one at district level and the other at tertiary level, in Kigali, Rwanda, from July 2012 to May 2013. Stillbirths and early neonatal deaths occurring after 22 completed weeks of gestation or more, or weighing at least 500 g, were included in the study. Factors contributing to mortality and potentially avoidable deaths, considering the local resources and feasibility, were identified using a three-delays model. Out of 8424 births, there were 269 perinatal deaths (106 macerated stillbirths, 63 fresh stillbirths, 100 early neonatal deaths) corresponding to a stillbirth rate of 20/1000 births and a perinatal mortality rate of 32/1000 births. In total, 250 perinatal deaths were available for audit. Factors contributing to mortality were ascertained for 79% of deaths. Delay in care-seeking was identified in 39% of deaths, delay in arriving at the health facility in 10%, and provision of suboptimal care at the health facility in 37%. Delay in seeking adequate care was commonly characterized by difficulties in recognising or reporting pregnancy-related danger signs. Lack of money was the major cause of delay in reaching a health facility. Delay in referrals, diagnosis and management of emergency obstetric cases were the most prominent contributors affecting the provision of appropriate and timely care by healthcare providers. Half of the perinatal deaths were judged to be potentially avoidable and 70% of these were fresh stillbirths and early neonatal deaths. Factors contributing to delays underlying perinatal mortality were identified in more than three-quarters of deaths. Half of the perinatal deaths were considered likely to be preventable and mainly related to modifiable maternal inadequate health-seeking behaviours and intrapartum suboptimal care. Strengthening the current roadmap strategy for accelerating the reduction of maternal and neonatal morbidity and mortality is needed for improved perinatal survival.

Perinatal period begins at 22 gestational weeks and ends seven days after birth. Perinatal mortality is an important quality indicator of the obstetric and pediatric care available, and representative of the population's health service. To know fetal, early neonatal, and perinatal dead rates, and them main mortality causes. Descriptive and retrospective study at IMSS's no. 32 UMAE (Monterrey, Nuevo León, México), from January 2002 to December 2006. Mortality rates during fetal and perinatal, or neonatal periods, were estimated per 1,000 births or 1,000 live born, respectively. There were 1,681 deaths: 747 stillbirths and 934 neonatal. Two hundred and nineteen (29.3%) stillbirths had 22 to 27 gestational weeks, and 528 (70.6%) had 28. Three hundred and sixty neonatal deaths (38.5%) occurred before 27th gestational week, 320 (34.2%) between weeks 28th and 35th, and 254 (27.1%) after 36 weeks of pregnancy. Seven hundred and sixty four neonates died within 0 to 6 days of life, and 170 (18%) between seventh to 28th days of life. Fetal, neonatal, early neonatal, and late neonatal mortality rates were 7.2 in 1,000 births, 9.08 in 1,000 live born, 7.42 in 1,000 live born, and 1.65 in 1,000 births, respectively, and overall perinatal mortality rate was 14.58 in 1,000 births. Stillbirth, early neonatal, and perinatal mortality rates of this study were under national mean. Main mortality causes (70%) were congenital defects and prematurity.

Perinatal statistics are one of the most essential outcome indicators used by many developed countries in order to evaluate perinatal services provided to newborns. In this retrospective study, we collected 15 years of perinatal data at King Khalid University Hospital in Riyadh, Saudi Arabia in order to determine stillbirth and other mortality rates in our institute and compare them with international figures. A total of 58,073 babies were evaluated. Data were collected from maternal and neonatal registry books and from perinatal mortality and morbidity meeting reports between 1994 and 2008. Data were entered and analyzed using Microsoft Office Excel 2007. The stillbirth rate was 11.7/1000, early neonatal death rate was 3.4/1000, perinatal mortality rate (PMR) was 14.9/1000, and corrected PMR was 11.9/1000. Our rates were not significantly different from those of North American and European ones. We noticed a dramatic reduction in the corrected PMR in the last 3 years of the study because of greater advancement in perinatal and neonatal care. Our mortality rates were comparable to the North American and European rates which may reflect the quality of perinatal care provided in our institute.

To estimate the recurrence risk of preterm delivery and estimate the perinatal mortality in repeated preterm deliveries. Prospective study in Tanzania of 18 176 women who delivered a singleton between 2000 and 2008 at KCMC hospital. The women were followed up to 2010 for consecutive births. A total of 3359 women were identified with a total of 3867 subsequent deliveries in the follow-up period. Recurrence risk of preterm birth and perinatal mortality was estimated using log-binomial regression and adjusted for potential confounders. For women with a previous preterm birth, the risk of preterm birth in a subsequent pregnancy was 17%. This recurrence risk was estimated to be 2.7-fold (95% CI: 2.1-3.4) of the risk of women with a previous term birth. The perinatal mortality of babies in a second preterm birth of the same woman was 15%. Babies born at term who had an older sibling that was born preterm had a perinatal mortality of 10%. Babies born at term who had an older sibling who was also born at term had a perinatal mortality of 1.7%. Previous delivery of a preterm infant is a strong predictor of future preterm births in Tanzania. Previous or repeated preterm births increase the risk of perinatal death substantially in the subsequent pregnancy. © 2013 Blackwell Publishing Ltd.

To examine whether disparities in stillbirth, and neonatal and perinatal mortality rates, between public and private hospitals are the result of differences in population characteristics and/or clinical practices. Retrospective cohort study. A metropolitan tertiary centre encompassing public and private hospitals. Women accessed care from either a private obstetrician or from public models of care - predominantly midwife-led care or care shared between midwives, general practitioners, and obstetricians. A total of 131 436 births during 1998-2013: 69 037 public and 62 399 private. Propensity score matching was used to select equal-sized public and private cohorts with similar characteristics. Logistic regression analysis was then used to explore the impact of public-private differences in the use of assisted reproductive technologies, plurality, major congenital anomalies, birth method, and gestational age. Stillbirth, and neonatal and perinatal mortality rates. After controlling for maternal and pregnancy factors, perinatal mortality rates were higher in the public than in the private cohort (adjusted odds ratio, aOR 1.53; 95% confidence interval, 95% CI 1.29-1.80; stillbirth aOR 1.56, 95% CI 1.26-1.94; neonatal death aOR 1.48, 95% CI 1.15-1.89). These disparities reduced by 15.7, 20.5, and 19.6%, respectively, after adjusting for major congenital anomalies, birth method, and gestational age. Perinatal mortality occurred more often among public than private births, and this disparity was not explained by population differences. Differences in clinical practices seem to be partly responsible. The impact of differences in clinical practices on maternal and neonatal morbidity was not examined. Further research is required. Private obstetrician-led care: more obstetric intervention and earlier births reduce perinatal mortality. Background Babies born in Australian public hospitals tend to die more often than those born in private hospitals. Our aim was to determine whether this pattern is a result of public-private differences in care or merely linked with differences in the characteristics of the two groups. In Australian private hospitals, a private obstetrician almost always provides continuing care to each woman during pregnancy and birth. Public hospitals provide a number of care options, which usually involve midwives and/or a family doctor. Method The study population included 131 436 births (52.5% public; 47.5% private) from 1998-2013 at a single metropolitan centre with co-located public and private facilities. To isolate the effect of differences in care, we used a statistical technique called propensity score matching to select a public group and a private group with similar characteristics and equal size. This enabled us to compare 'apples with apples' when comparing public versus private perinatal death rates. Perinatal deaths include stillbirths and babies that die within 28 days of birth. Main findings After matching and after accounting for different patterns in the use of fertility treatments and multiple-birth pregnancies (such as twins), babies born in the public sector were approximately 1.5 times more likely to die than babies born in the private sector. This difference was reduced to 1.3 times more likely to die than babies born in the private sector after taking into account other factors that could skew the data, such as major congenital anomalies, birth method, and duration of pregnancy. Limitations This was a single-centre study, so the results may not apply to all settings. Despite our efforts to create highly similar public and private cohorts, some differences between the groups are likely to have remained and this may have affected the results. Implications Our findings suggest that private obstetrician-led care has a beneficial impact on perinatal deaths, despite, or possibly because of, higher obstetric intervention rates and earlier births in the private hospital.

Perinatal mortality is a major cause of loss in the sheep industry. Our aim was to explore time trends in crude population stillbirth and neonatal mortality rates in Norway. We used data on 6,435,715 lambs from flocks enrolled in the Norwegian Sheep Recording System (NSRS) from 2000 through 2010 for descriptive analysis of trends. Longitudinal patterns of mortality rates were compared for lambs within different levels of variables suspected to be associated with perinatal loss. There was an approximately linear increase in the annual proportion of stillborn lambs during the study period, from 3.3 % in 2000 to 4.7 % in 2010. In the same time period, average litter size of ewes in NSRS flocks increased from 2.00 to 2.19. However, a steady rise in stillbirth rate was observed within each litter size group, suggesting a gradually increasing impact on stillbirth risk of other, yet unidentified, factors. Average flock size increased during the study period. The highest stillbirth rates were found in the largest and smallest flocks. Early neonatal mortality rates (0-5 days of life) varied from year to year (minimum 2.2 %, maximum 3.2 %) and were invariably higher among triplets and quadruplets than among singletons and twins. Annual fluctuations were parallel within the various litter sizes. A significant overall decreasing trend was present within all litter sizes with the exception of singletons. Weather data for the prime lambing months (April and May) 2000-2010 indicated a relationship between low temperatures and high neonatal mortality rates. At the flock level, there was a significant positive correlation between stillbirths and early neonatal mortality rates (r = 0.13), between stillbirth rates in two consecutive years (r = 0.43) and between early neonatal mortality rates in two consecutive years (r = 0.40). The substantial increase in ovine stillbirth rate in recent years in Norway was to some extent related to a corresponding increase in the proportion of lambs in triplet or larger litters; however, other factors apparently have contributed. Early neonatal mortality rate exhibited year-to-year variations, partly following temperature fluctuations, which is somewhat unexpected, considering that lambing mainly occurs indoors in Norway.

Predictors of Perinatal Mortality Associated with Placenta Previa and Placental Abruption: An Experience from a Low Income Country

A retrospective cohort study design was used to assess predictors of perinatal mortality in women with placenta previa and abruption between January 2006 and December 2011. Four hundred thirty-two women (253 with placenta previa and 179 with placental abruption) were eligible for analysis. Binary logistic regression, Kaplan-Meier survival curve, and receiver operating characteristic (ROC) curve were used. On admission, 77% of the women were anaemic (<12 gm/dL) with mean haemoglobin level of 9.0 ± 3.0 gm/dL. The proportion of overall severe anaemia increased from about 28% on admission to 41% at discharge. There were 50% perinatal deaths (neonatal deaths of less than seven days of age and fetal deaths after 28 weeks of gestation). In the adjusted odds ratios, lengthy delay in accessing hospital care, prematurity, anaemia in the mothers, and male foetuses were independent predictors of perinatal mortality. The haemoglobin level at admission was more sensitive and more specific than prematurity in the prediction of perinatal mortality. The proportion of severe anaemia and perinatal mortality was probably one of the highest in the world. PMID:25002975

Perinatal mortality in second- vs firstborn twins: a matter of birth size or birth order?

Second-born twins on average weigh less than first-born twins and have been reported at an elevated risk of perinatal mortality. Whether the risk differences depend on their relative birth size is unknown. The present study aimed to evaluate the association of birth order with perinatal mortality by birth order-specific weight difference in twin pregnancies. In a retrospective cohort study of 258,800 twin pregnancies without reported congenital anomalies using the US matched multiple birth data 1995-2000 (the available largest multiple birth dataset), conditional logistic regression was applied to estimate the odds ratio (OR) of perinatal death adjusted for fetus-specific characteristics (sex, presentation, and birthweight for gestational age). Comparing second vs first twins, the risks of perinatal death were similar if they had similar birthweights (within 5%) and were increasingly higher if second twins weighed progressively less (adjusted ORs were 1.37, 1.90, and 3.94 if weighed 5.0-14.9%, 15.0-24.9%, and ≥25.0% less, respectively), and progressively lower if they weighed increasingly more (adjusted ORs were 0.67, 0.63, and 0.36 if weighed 5.0-14.9%, 15.0-24.9%, and ≥25.0% more, respectively) (all P < .001). The perinatal mortality rates were not significantly different in cesarean deliveries or preterm (<37 weeks) vaginal deliveries but were significantly higher in second twins in term vaginal deliveries (3.1 vs 1.8 per 1000; adjusted OR, 2.15; P < .001). Perinatal mortality risk differences in second vs first twins depend on their relative birth size. Vaginal delivery at term is associated with a substantially greater risk of perinatal mortality in second twins. Copyright © 2014 Mosby, Inc. All rights reserved.

Following a perinatal death, a formal standardised multi-disciplinary review should take place, to learn from the death of a baby and facilitate improvements in future care. It has been recommended that bereaved parents should be offered the opportunity to give feedback on the care they have received and integrate this feedback into the perinatal mortality review process. However, the MBRRACE-UK Perinatal Confidential Enquiry (2015) found that only one in 20 cases parental concerns were included in the review. Although guidance suggests parental opinion should be sought, little evidence exists on how this may be incorporated into the perinatal mortality review process. The purpose of the PARENTS study was to investigate bereaved parents' views on involvement in the perinatal mortality review process. A semi-structured focus group of 11 bereaved parents was conducted in South West England. A purposive sampling technique was utilised to recruit a diverse sample of women and their partners who had experienced a perinatal death more than 6 months prior to the study. A six-stage thematic analysis was followed to explore parental perceptions and expectations of the perinatal mortality review process. Four over-arching themes emerged from the analysis: transparency; flexibility combined with specificity; inclusivity; and a positive approach. It was evident that the majority of parents were supportive of their involvement in the perinatal mortality review process and they wanted to know the outcome of the meeting. It emerged that an individualised approach should be taken to allow flexibility on when and how they could contribute to the process. The emotional aspects of care should be considered as well as the clinical care. Parents identified that the whole care pathway should be examined during the review including antenatal, postnatal, and neonatal and community based care. They agreed that there should be an opportunity for parents to give feedback on both good and poor aspects of their care. Parents were unaware that a review of their baby's death took place in the hospital. Parental involvement in the perinatal mortality review process would promote an open culture in the healthcare system and learning from adverse events including deaths. Further research should focus on designing and evaluating a perinatal mortality review process where parental feedback will be integral.

We wanted to compare customised and population standards for defining smallness for gestational age (SGA) in the assessment of perinatal mortality risk associated with parity and maternal size. Population-based cohort study. Sweden. Swedish Birth Registry database 1992-1995 with 354 205 complete records. Coefficients were derived and applied to determine SGA by the fully customised method, or by adjustment for fetal sex only, and using the same fetal weight standard. Perinatal deaths and rates of small for gestational age (SGA) babies within subgroups stratified by parity, body mass index (BMI) and maternal size within the BMI range of 20.0-24.9. Perinatal mortality rates (PMR) had a U-shaped distribution in parity groups, increased proportionately with maternal BMI, and had no association with maternal size within the normal BMI range. For each of these subgroups, SGA rates determined by the customised method showed strong association with the PMR. In contrast, SGA based on uncustomised, population-based centiles had poor correlation with perinatal mortality. The increased perinatal mortality risk in pregnancies of obese mothers was associated with an increased risk of SGA using customised centiles, and a decreased risk of SGA using population-based centiles. The use of customised centiles to determine SGA improves the identification of pregnancies which are at increased risk of perinatal death.

Background Cree births in Quebec are characterized by the highest reported prevalence of macrosomia (~35%) in the world. It is unclear whether Cree births are at greater elevated risk of perinatal and infant mortality than other First Nations relative to non-Aboriginal births in Quebec, and if macrosomia may be related. Methods This was a population-based retrospective birth cohort study using the linked birth-infant death database for singleton births to mothers from Cree (n = 5,340), other First Nations (n = 10,810) and non-Aboriginal (n = 229,960) communities in Quebec, 1996–2010. Community type was ascertained by residential postal code and municipality name. The primary outcomes were perinatal and infant mortality. Results Macrosomia (birth weight for gestational age >90th percentile) was substantially more frequent in Cree (38.0%) and other First Nations (21.9%) vs non-Aboriginal (9.4%) communities. Comparing Cree and other First Nations vs non-Aboriginal communities, perinatal mortality rates were 1.52 (95% confidence intervals 1.17, 1.98) and 1.34 (1.10, 1.64) times higher, and infant mortality rates 2.27 (1.71, 3.02) and 1.49 (1.16, 1.91) times higher, respectively. The risk elevations in perinatal and infant death in Cree communities attenuated after adjusting for maternal characteristics (age, education, marital status, parity), but became greater after further adjustment for birth weight (small, appropriate, or large for gestational age). Conclusions Cree communities had greater risk elevations in perinatal and infant mortality than other First Nations relative to non-Aboriginal communities in Quebec. High prevalence of macrosomia did not explain the elevated risk of perinatal and infant mortality in Cree communities. PMID:27517613

To determine the pregnancy termination rate, and perinatal and 1-year infant mortality rates following prenatally-detected congenital heart disease (CHD) and trends over an 11-year period. Between 1994 and 2005, 1603 gravidas underwent fetal echocardiography in our institution, in which 378 fetuses were diagnosed with CHD. The study period was divided into the following three groups for time-trend analysis: 1994-1997, 1998-2001, and 2002-2005. Data regarding gestational age at diagnosis and delivery, the presence of extracardiac or chromosomal abnormalities, pregnancy termination rate, and perinatal and 1-year mortalities were collected by review of medical records and telephone interviews. Among 378 fetuses with a prenatally-detected CHD, complete perinatal and infant outcomes were available for 336 fetuses (88.9%). There was a gradual increase in prenatally-detected CHD by fetal echocardiography during the study period (1994-1997, 10.3%; 1998-2001, 17.3%; and 2002-2005, 24.3%). The mean gestational ages at diagnosis and delivery were 27.2 +/- 5.6 and 37.8 +/- 2.9 weeks, respectively. Overall, the pregnancy termination rate in this study population was 20.2% and the perinatal and 1-year infant mortality rates were 6.3% and 9.7%, respectively. Among the fetuses who underwent cardiac surgery, surgical mortality occurred in two (3.8%); both died more than 1 month after surgery. Although the pregnancy termination rates remained unchanged, there was a significant decrease in perinatal and 1-year infant mortality rates over the study period. Although the perinatal and 1-year infant mortalities following prenatally-detected CHD have continued to decrease significantly during the past 11 years, pregnancy termination rates have remained unchanged.

Syphilis is a persistent cause of perinatal mortality in Rio de Janeiro, Brazil, where this study was performed using data from the mortality data system and investigational reports for fetal and neonatal deaths, mandatory in municipal maternity hospitals. From 1996 to 1998, 13.1% of fetal deaths and 6.5% of neonatal deaths in municipal maternity hospitals were due to congenital syphilis. From 1999 to 2002, the proportions were 16.2% and 7.9%, respectively. For the city of Rio de Janeiro as a whole from 1999 and 2002, the proportions were 5.4% of fetal deaths and 2.2% of neonatal deaths. The perinatal mortality rate due to congenital syphilis remains stable in Rio de Janeiro, despite efforts initiated with congenital syphilis elimination campaigns in 1999 and 2000. We propose that the perinatal mortality rate due to congenital syphilis be used as an impact indicator for activities to control and eliminate congenital syphilis, based on the investigational reports for fetal and neonatal deaths. Such reports could be extended to the surveillance of other avoidable perinatal disease outcomes.

Is perinatal mortality rate higher among births born following assisted reproductive technology (ART) compared to non-ART births? Overall perinatal mortality rates in ART births was higher compared to non-ART births, but gestational age-specific perinatal mortality rate of ART births was lower for very preterm and moderate to late preterm births. Births born following ART are reported to have higher risk of adverse perinatal outcomes compared to non-ART births. This population-based retrospective cohort study included 407 368 babies (391 952 non-ART and 15 416 ART)-393 491 singletons and 10 877 twins or high order multiples. All births (≥20 weeks of gestation and/or ≥400 g of birthweight) in five states and territories in Australia during the period 2007-2009 were included in the study, using National Perinatal Data Collection (NPDC). Primary outcome measures were rates of stillbirth, neonatal and perinatal deaths. Adjusted odds ratio (AOR) and 95% confidence interval (CI) were used to estimate the likelihood of perinatal death. Rates of multiple birth and low birthweight were significantly higher in ART group compared to the non-ART group (P < 0.01). Overall perinatal mortality rate was significantly higher for ART births (16.5 per 1000 births, 95% CI 14.5-18.6), compared to non-ART births (11.3 per 1000 births, 95% CI 11.0-11.6) (AOR 1.45, 95% CI 1.26-1.68). However, gestational age-specific perinatal mortality rate of ART births (including both singletons and multiples) was lower for very preterm (<32 weeks' gestation) and moderate to late preterm births (32-36 weeks' gestation) (AOR 0.61, 95% CI 0.53-0.70 and AOR 0.61, 95% CI 0.53-0.70, respectively) compared to non-ART births. Congenital abnormality and spontaneous preterm were the most common causes of neonatal deaths in both ART and non-ART group. Due to different cut-off limit for perinatal period in Australia, the results of this study should be interpreted with cautions for other countries. Australian definition of perinatal period commences at 20 completed weeks (140 days) of gestation and ends 27 completed days after birth which is different from the definition by World Health Organisation (commences at 22 completed weeks (154 days) of gestation and ends seven completed days after birth) and by Centers for Disease Control and Prevention (includes infant deaths under age 7 days and fetal deaths at 28 weeks of gestation or more). Preterm birth is the single most important contributing factor to increased risk of perinatal mortality among ART singletons compared to non-ART singletons. Further research on reducing early preterm delivery, with the aim of reducing the perinatal mortality among ART births is needed. Couples who access ART treatment should be fully informed regarding the risk of preterm birth and subsequent risk of perinatal death. There was no funding associated with this study.

To assess the association between perinatal losses and mother's long-term mortality and modification by surviving children and attained education. A population-based cohort study. Norwegian national registries. We followed 652 320 mothers with a first delivery from 1967 and completed reproduction before 2003, until 2010 or death. We excluded mothers with plural pregnancies, without information on education (0.3%) and women born outside Norway. Main outcome measures were age-specific (40-69 years) cardiovascular and non-cardiovascular mortality. We calculated mortality in mothers with perinatal losses, compared with mothers without, and in mothers with one loss by number of surviving children in strata of mothers' attained education (<11 years (low), ≥11 years (high)). Mothers with perinatal losses had increased crude mortality compared with mothers without; total: HR 1.3 (95% CI 1.3 to 1.4), cardiovascular: HR 1.8 (1.5 to 2.1), non-cardiovascular: HR 1.3 (1.2 to 1.4). Childless mothers with one perinatal loss had increased mortality compared with mothers with one child and no loss; cardiovascular: low education HR 2.7 (1.7 to 4.3), high education HR 0.91 (0.13 to 6.5); non-cardiovascular: low education HR 1.6 (1.3 to 2.2), high education HR 1.8 (1.1 to 2.9). Mothers with one perinatal loss, surviving children and high education had no increased mortality, whereas corresponding mothers with low education had increased mortality; cardiovascular: two surviving children HR 1.7 (1.2 to 2.4), three or more surviving children HR 1.6 (1.1 to 2.4); non-cardiovascular: one surviving child HR 1.2 (1.0 to 1.5), two surviving children HR 1.2 (1.1 to 1.4). Irrespective of education, we find excess mortality in childless mothers with a perinatal loss. Increased mortality in mothers with one perinatal loss and surviving children was limited to mothers with low education. Published by the BMJ Publishing Group Limited.

To assess differences in small-for-gestational age (SGA) classifications for the detection of neonates with increased perinatal mortality risk among obese women and subsequently assess the association between prepregnancy body mass index (BMI) status and SGA. Hospital-based cohort. Twelve US clinical centres (2002-08). A total of 114 626 singleton, nonanomalous pregnancies. Data were collected using electronic medical record abstraction. Relative risks (RR) with 95% CI were estimated. SGA trends (birthweight < 10th centile) classified using population-based (SGA POP ), intrauterine (SGA IU ) and customised (SGA CUST ) references were assessed. The SGA-associated perinatal mortality risk was estimated among obese women. Using the SGA method most associated with perinatal mortality, the association between prepregnancy BMI and SGA was estimated. The overall perinatal mortality prevalence was 0.55% and this increased significantly with increasing BMI (P < 0.01). Among obese women, SGA IU detected the highest proportion of perinatal mortality cases (2.49%). Perinatal mortality was 5.32 times (95% CI 3.72-7.60) more likely among SGA IU neonates than non-SGA IU neonates. This is in comparison with the 3.71-fold (2.49-5.53) and 4.81-fold (3.41-6.80) increased risk observed when SGA POP and SGA CUST were used, respectively. Compared with women of normal weight, overweight women (RR = 0.82, 95% CI 0.78-0.86) and obese women (RR = 0.80; 95% CI 0.75-0.83) had a lower risk for delivering an SGA IU neonate. Among obese women, the intrauterine reference best identified neonates at risk of perinatal mortality. Based on SGA IU , SGA is less common among obese women but these SGA babies are at a high risk of death and remain an important group for surveillance. SGA is less common among obese women but these SGA babies are at a high risk of death. Published 2016. This article is a U.S. Government work and is in the public domain in the USA.

The computer laboratory of the Research Institute for the Care of Mother and Child in Prague performs annually a countrywide analysis of perinatal outcome in order to obtain a background for the preparation of the optimal strategy for improving perinatal care in CSR in the future. The total as well as weight specific perinatal mortality rate further sub-divided into early neonatal death rate and late fetal death rate and differentiated according to the birthweight, was correlated with the incidence of different factors influencing the perinatal mortality rate both countrywide and for each of the eight provinces of CSR. This way a correlation was found between some of the mentioned perinatal outcomes and e.g. instrumental equipment of obstetrical departments and neonatal intensive care units, frequency of caesarean sections, or transport of LBW newborns in incubators or "in utero" etc. The results of this analysis have proved that there still remain in some provinces opportunity for further decrease in perinatal mortality due to the incomplete observance of the two intervention strategies "Risk approach" and "New technology" which were introduced in the whole country during the last 10 years.

Pregnancy-induced or gestational hypertension is a common pregnancy complication. Paradoxically, gestational hypertension has been associated with a protective effect against perinatal mortality in twin pregnancies in analytic models (logistic regression) without accounting for survival time. Whether this effect is real remains uncertain. This study aimed to validate the impact of gestational hypertension on perinatal mortality in twin pregnancies using a survival analysis approach. This was a retrospective cohort study of 278,821 twin pregnancies, using the U.S. 1995-2000 matched multiple birth dataset (the largest dataset available for multiple births). Cox proportional hazard models were applied to estimate the adjusted hazard ratios (aHR) of perinatal death (stillbirth and neonatal death) comparing gestational hypertensive vs. non-hypertensive pregnancies controlling for maternal characteristics and twin cluster-level dependence. Comparing births in gestational hypertensive vs. non-hypertensive twin pregnancies, perinatal mortality rates were significantly lower (1.20% vs. 3.38%), so were neonatal mortality (0.72% vs. 2.30%) and stillbirth (0.48% vs. 1.10%) rates. The aHRs (95% confidence intervals) were 0.34 (0.31-0.38) for perinatal death, 0.31 (0.27-0.34) for neonatal death, and 0.45 (0.38-0.53) for stillbirth, respectively. The protective effect of gestational hypertension against perinatal death became weaker over advancing gestational age; the aHRs in very preterm (<32 weeks), mild preterm (32-36 weeks) and term (37+ weeks) births were 0.29, 0.48 and 0.76, respectively. The largest risk reductions in neonatal mortality were observed for infections and immaturity-related conditions. Gestational hypertension appears to be beneficial for fetal survival in twin pregnancies, especially in those ending more prematurely or for deaths due to infections and immaturity-related conditions. Prospective studies are required to rule out the possibility of unmeasured confounders.

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

Background Perinatal death is a devastating experience for the mother and of concern in clinical practice. Regular perinatal audit may identify suboptimal care related to perinatal deaths and thus appropriate measures for its reduction. The aim of this study was to perform a qualitative perinatal audit of intrapartum and early neonatal deaths and propose means of reducing the perinatal mortality rate (PMR). Methods From 1st August, 2007 to 31st December, 2007 we conducted an audit of perinatal deaths (n = 133) with birth weight 1500 g or more at Muhimbili National Hospital (MNH). The audit was done by three obstetricians, two external and one internal auditors. Each auditor independently evaluated the cases narratives. Suboptimal factors were identified in the antepartum, intrapartum and early neonatal period and classified into three levels of delay (community, infrastructure and health care). The contribution of each suboptimal factor to adverse perinatal outcome was identified and the case graded according to possible avoidability. Degree of agreement between auditors was assessed by the kappa coefficient. Results The PMR was 92 per 1000 total births. Suboptimal factors were identified in 80% of audited cases and half of suboptimal factors were found to be the likely cause of adverse perinatal outcome and were preventable. Poor foetal heart monitoring during labour was indirectly associated with over 40% of perinatal death. There was a poor to fair agreement between external and internal auditors. Conclusion There are significant areas of care that need improvement. Poor monitoring during labour was a major cause of avoidable perinatal mortality. This type of audit was a good starting point for quality assurance at MNH. Regular perinatal audits to identify avoidable causes of perinatal deaths with feed back to the staff may be a useful strategy to reduce perinatal mortality. PMID:19765312

Pre-term delivery is one of the leading causes of foetal and perinatal mortality. However, perinatal risk factors associated with intra-partum foetal death in preterm deliveries have not been well studied. To analyse foetal mortality and perinatal risk factors associated with intra-partum foetal mortality in pregnancies of less than 32 weeks gestational age. The study included all preterm deliveries between 22 and 31 +1 weeks gestational age (WGA), born in a tertiary-referral hospital, over a period of 7 years (2008-2014). A logistic regression model was used to identify perinatal risk factors associated with intra-partum foetal mortality (foetal malformations and chromosomal abnormalities were excluded). During the study period, the overall foetal mortality was 63.1% (106/168) (≥22 weeks of gestation) occurred in pregnancies of less than 32 WGA. A total of 882 deliveries between 22 and 31+6 weeks of gestation were included for analysis. The rate of foetal mortality was 11.3% (100/882). The rate of intra-partum foetal death was 2.6% (23/882), with 78.2% (18/23) of these cases occurring in hospitalised pregnancies. It was found that Assisted Reproductive Techniques, abnormal foetal ultrasound, no administration of antenatal steroids, lower gestational age, and small for gestational age, were independent risk factors associated with intra-partum foetal mortality. This study showed that there is a significant percentage intra-partum foetal mortality in infants between 22 and 31+6 WGA. The analysis of intrapartum mortality and risk factors associated with this mortality is of clinical and epidemiological interest to optimise perinatal care and improve survival of preterm infants.

In many developing countries, the majority of births are attended by traditional birth attendants, who lack formal training in neonatal resuscitation and other essential care required by the newly born infant. In these countries, the major causes of neonatal mortality are birth asphyxia, infection, and low-birth-weight/prematurity. Death from these causes is potentially modifiable using low-cost interventions, including neonatal resuscitation training. The purpose of this study was to evaluate the effect on perinatal mortality of training birth attendants in a rural area of the Democratic Republic of Congo (DRC) using two established programs. This study, a secondary analysis of DRC-specific data collected during a multi-country study, was conducted in two phases. The effect of training using the WHO Essential Newborn Care (ENC) program was evaluated using an active baseline design, followed by a cluster randomized trial of training using an adaptation of a neonatal resuscitation program (NRP). The perinatal mortality rates before ENC, after ENC training, and after randomization to additional NRP training or continued care were compared. In addition, the influence of time following resuscitation training was investigated by examining change in perinatal mortality during sequential three-month increments following ENC training. More than two-thirds of deliveries were attended by traditional birth attendants and occurred in homes; these proportions decreased after ENC training. There was no apparent decline in perinatal mortality when the outcome of all deliveries prior to ENC training was compared to those after ENC but before NRP training. However, there was a gradual but significant decline in perinatal mortality during the year following ENC training (RR 0.73; 95% CI: 0.56-0.96), which was independently associated with time following training. The decline was attributable to a decline in early neonatal mortality. NRP training had no demonstrable effect on early neonatal mortality. Training DRC birth attendants using the ENC program reduces perinatal mortality. However, a period of utilization and re-enforcement of training may be necessary before a decline in mortality occurs. ENC training has the potential to be a low cost, high impact intervention in developing countries. This trial has been registered at http://www.clinicaltrials.gov (identifier NCT00136708).

To determine whether babies in an area of Britain with unusually high perinatal mortality have different patterns of fetal growth to those born elsewhere in the country. Measurement of body size in newborn babies. Burnley (perinatal mortality in 1988 15.9/1000 total births) and Salisbury (perinatal mortality 10.8/1000 total births), England. Subjects comprised 1544 babies born in Burnley, Pendle, and Rossendale Health District, and 1025 babies born in Salisbury Health District. Birthweight, length, head, arm and abdominal circumferences, and placental weight were determined. Compared with babies born in Salisbury, Burnley babies had lower mean birthweight (difference 116 g, 95% confidence interval (CI) 77,154), smaller head circumferences (difference 0.3 cm, 95% CI 0.2, 0.4), and were thinner as measured by arm circumference (difference 0.3 cm, 95% CI 0.3, 0.4), abdominal circumference (difference 0.5 cm, 95% CI 0.4, 0.6) and ponderal index (difference 0.8 kg/m3, 95% CI 0.6, 1.0). The ratio of placental weight to birthweight was higher in Burnley (difference 0.6%, 95% CI 0.4, 0.9). These differences were found in boys and girls and did not depend on differences in duration of gestation or on the different ethnic mix of the two districts. Mothers in Burnley were younger, shorter in stature, had had more children, were of lower social class, and more of them smoked during pregnancy than mothers in Salisbury. These differences did not explain the greater thinness of their babies. Babies born in Burnley, an area with high perinatal mortality, are thin. The reason is unknown. Poor maternal nutrition is suspected because Burnley babies have a higher ratio of placental weight to birthweight. The greater thinness at birth of Burnley babies could have long term consequences, including higher rates of cardiovascular disease.

Whether gestational age per se increases perinatal mortality in post-term pregnancy is unclear. We aimed at assessing gestational week specific perinatal mortality in small-for-gestational-age (SGA) and non-SGA term and post-term gestations, and specifically to evaluate whether the relation between post-term gestation and perinatal mortality differed before and after ultrasound was introduced as the standard method of gestational age estimation. A population-based cohort study, using data from the Medical Birth Registry of Norway (MBRN), 1967-2006, was designed. Singleton births at 37 through 44 gestational weeks (n = 1 855 682), excluding preeclampsia, diabetes and fetal anomalies, were included. Odds ratios (OR) with 95% confidence intervals (CI) for perinatal mortality and stillbirth in SGA and non-SGA births by gestational week were calculated. SGA infants judged post-term by LMP had significantly higher perinatal mortality than post-term non-SGA infants at 40 weeks, independent of time period (highest during 1999-2006 [OR 9.8, 95% CI: 5.7-17.0]). When comparing years before (1967-1986) versus after (1987-2006) ultrasound was introduced, there was no decrease in the excess mortality for post-term SGA versus non-SGA births (ORs from 6.1 [95% CI: 5.2-7.1] to 6.7 [5.2-8.5]), while mortality at 40 weeks decreased significantly (ORs from 4.6, [4.0-5.3] to 3.2 [2.5-3.9]). When assessing stillbirth risk (1999-2006), more than 40% of SGA stillbirths (11/26) judged to be ≥41 weeks by LMP were shifted to lower gestational ages using ultrasound estimation. Mortality risk in post-term infants was strongly associated with growth restriction. Such infants may erroneously be judged younger than they are when using ultrasound estimation, so that the routine assessment for fetal wellbeing in the prolonged gestation may be given too late.

The objective of this study was to verify the reliability of the classifications of perinatal mortality causes. An independent observer coded the cases of perinatal death (n = 152) collected in the Encuesta Confidencial de Mortalidad Perinatal de Barcelona (ECMP, Confidential Perinatal Mortality Inquiry of Barcelona), by using both the Aberdeen classification system (regarding obstetric factors) and the Wigglesworth classification system (according to the initial pathological cause), with the same information used previously by the ECMP Commission. For the Aberdeen classification, the observed concordance index (Po) was 86% and the Kappa coefficient (K) 0.77 (95% CI: 0.68-0.86). For the Wigglesworth classification, the figures were 89% and 0.82 (95% CI: 0.74-0.90), respectively. The disagreement was mainly due to differences in the interpretation of the sequence of death, minimal information available in order to classify the cause of death, and misunderstanding of the existing information. To a lesser extent, the disagreement was caused by a failure to comply with the rules laid down for classifications. The assessment of the causes of death was not significantly influenced by birth weight, gestational age, time of death or the presence of necropsy. These results support the use of classifications of perinatal mortality causes in the context of confidential inquiries.

Intrapartum complications increase the risk of perinatal deaths. However, population-based data from developing countries assessing the contribution of intrapartum complications to perinatal deaths is scarce. Using data from a cohort of pregnant women followed between 2011 and 2013 in Bangladesh, this study examined the rate and types of intrapartum complications, the association of intrapartum complications with perinatal mortality, and if facility delivery modified the risk of intrapartum-related perinatal deaths. Trained community health workers (CHWs) made two-monthly home visits to identify pregnant women, visited them twice during pregnancy and 10 times in the first two months postpartum. During prenatal visits, CHWs collected data on women's prior obstetric history, socio-demographic status, and complications during pregnancy. They collected data on intrapartum complications, delivery care, and pregnancy outcome during the first postnatal visit within 7 days of delivery. We examined the association of intrapartum complications and facility delivery with perinatal mortality by estimating odds ratios (OR) and 95% confidence intervals (CI) adjusting for covariates using multivariable logistic regression analysis. The overall facility delivery rate was low (3922/24 271; 16.2%). Any intrapartum complications among pregnant women were 20.9% (5,061/24,271) and perinatal mortality was 64.7 per 1000 birth. Compared to women who delivered at home, the risk of perinatal mortality was 2.4 times higher (OR = 2.40; 95% CI = 2.08-2.76) when delivered in a public health facility and 1.3 times higher (OR = 1.32, 95% CI = 1.06-1.64) when delivered in a private health facility. Compared to women who had no intrapartum complications and delivered at home, women with intrapartum complications who delivered at home had a substantially higher risk of perinatal mortality (OR = 3.45; 95% CI = 3.04-3.91). Compared to women with intrapartum complications who delivered at home, the risk of perinatal mortality among women with intrapartum complications was 43.0% lower for women who delivered in a public health facility (OR = 0.57; 95% CI = 0.42-0.78) and 58.0% lower when delivered in a private health facility (OR = 0.42; 95% CI = 0.28-0.63). Maternal health programs need to promote timely recognition of intrapartum complications and delivery in health facilities to improve perinatal outcomes, particularly in populations where overall facility delivery rates are low. The differential risk between public and private health facilities may be due to differences in quality of care. Efforts should be made to improve the quality of care in all health facilities.

National medical projects are carried out according to medical care plans directed by the Medical Care Act of Japan. In order to improve Japanese perinatal medical care, it is necessary to determine the factors that might influence perinatal outcome. Statistical data of births and perinatal deaths were obtained for all municipalities in Japan from 2008 to 2012 from the Portal Site of Official Statistics of Japan (e-Stat). The perinatal mortality of all 349 Japanese secondary medical care zones was calculated. The number of neonatal intensive care units (NICUs), maternal-fetal intensive care units (MFICUs), pediatricians and obstetricians in 2011 were also obtained from e-Stat. Nine secondary medical care zones in two prefectures, Fukushima (7) and Miyagi (2) were excluded to eliminate the influence of the 2011 Great East Japan Earthquake. The 340 secondary medical care zones were divided into three groups according to population size and density: metropolis, provincial city, and depopulation. The number of secondary medical care zones in each group were 52, 168, and 120, respectively. The secondary medical care zones in the depopulation group had fewer pediatricians and significantly fewer NICUs and MFICUs than the metropolis group, but there was no significant difference in perinatal mortality. The only independent risk factor for high perinatal mortality, determined by multivariable analysis, was the absence of an NICU (P = 0.011). To consider directions in perinatal medical care, planned arrangement and appropriate access to NICUs is indispensable. © 2016 Japan Society of Obstetrics and Gynecology.

From 1970 to 1972, there were 216 perinatal deaths among 5595 newborns at the I. Frauenklinik der Universität München. 54 of these deaths were children of foreign workers (so-called "Gastarbeiter"). The data have been processed on punch cards and analysed by a computer. The differences noted underwent significance testing by the CHI-Quadrat test. Only statistical significant results are published. The perinatal mortality in the above period shows no difference between foreign and German ward patients. There is, however, a significant lower perinatal mortality in private patients. We feel that this difference is due to a significant lower rate of prematures in the private patient group. The cocial status as well as higher interest and motivation in health resulting in better prenatal care are discussed as causal reasons for this fact.

Maternal and perinatal mortality continue to be a high priority problem on the health agendas of less developed countries. Despite the progress made in the last decade to quantify the magnitude of maternal mortality, few interventions have been implemented with the intent to measure impact directly on maternal or perinatal deaths. The success of interventions implemented in less developed countries to reduce mortality has been questioned, in terms of the tendency to maintain a clinical perspective with a focus on purely medical care separate from community-based approaches that take cultural and social aspects of maternal and perinatal deaths into account. Our innovative approach utilizes both the clinical and community perspectives; moreover, our study will report the weight that each of these components may have had on reducing perinatal mortality and increasing institution-based deliveries. A matched pair cluster-randomized trial will be conducted in clinics in four rural indigenous districts with the highest maternal mortality ratios in Guatemala. The individual clinic will serve as the unit of randomization, with 15 matched pairs of control and intervention clinics composing the final sample. Three interventions will be implemented in indigenous, rural and poor populations: a simulation training program for emergency obstetric and perinatal care, increased participation of the professional midwife in strengthening the link between traditional birth attendants (TBA) and the formal health care system, and a social marketing campaign to promote institution-based deliveries. No external intervention is planned for control clinics, although enhanced monitoring, surveillance and data collection will occur throughout the study in all clinics throughout the four districts. All obstetric events occurring in any of the participating health facilities and districts during the 18 months implementation period will be included in the analysis, controlling for the cluster design. Our main outcome measures will be the change in perinatal mortality and in the proportion of institution-based deliveries. A unique feature of this protocol is that we are not proposing an individual intervention, but rather a package of interventions, which is designed to address the complexities and realities of maternal and perinatal mortality in developing countries. To date, many other countries, has focused its efforts to decrease maternal mortality indirectly by improving infrastructure and data collection systems rather than on implementing specific interventions to directly improve outcomes.

Methods/Design A matched pair cluster-randomized trial will be conducted in clinics in four rural indigenous districts with the highest maternal mortality ratios in Guatemala. The individual clinic will serve as the unit of randomization, with 15 matched pairs of control and intervention clinics composing the final sample. Three interventions will be implemented in indigenous, rural and poor populations: a simulation training program for emergency obstetric and perinatal care, increased participation of the professional midwife in strengthening the link between traditional birth attendants (TBA) and the formal health care system, and a social marketing campaign to promote institution-based deliveries. No external intervention is planned for control clinics, although enhanced monitoring, surveillance and data collection will occur throughout the study in all clinics throughout the four districts. All obstetric events occurring in any of the participating health facilities and districts during the 18 months implementation period will be included in the analysis, controlling for the cluster design. Our main outcome measures will be the change in perinatal mortality and in the proportion of institution-based deliveries. Discussion A unique feature of this protocol is that we are not proposing an individual intervention, but rather a package of interventions, which is designed to address the complexities and realities of maternal and perinatal mortality in developing countries. To date, many other countries, has focused its efforts to decrease maternal mortality indirectly by improving infrastructure and data collection systems rather than on implementing specific interventions to directly improve outcomes.

Background Pregnancy-induced or gestational hypertension is a common pregnancy complication. Paradoxically, gestational hypertension has been associated with a protective effect against perinatal mortality in twin pregnancies in analytic models (logistic regression) without accounting for survival time. Whether this effect is real remains uncertain. This study aimed to validate the impact of gestational hypertension on perinatal mortality in twin pregnancies using a survival analysis approach. Methods This was a retrospective cohort study of 278,821 twin pregnancies, using the U.S. 1995–2000 matched multiple birth dataset (the largest dataset available for multiple births). Cox proportional hazard models were applied to estimate the adjusted hazard ratios (aHR) of perinatal death (stillbirth and neonatal death) comparing gestational hypertensive vs. non-hypertensive pregnancies controlling for maternal characteristics and twin cluster-level dependence. Results Comparing births in gestational hypertensive vs. non-hypertensive twin pregnancies, perinatal mortality rates were significantly lower (1.20% vs. 3.38%), so were neonatal mortality (0.72% vs. 2.30%) and stillbirth (0.48% vs. 1.10%) rates. The aHRs (95% confidence intervals) were 0.34 (0.31–0.38) for perinatal death, 0.31 (0.27–0.34) for neonatal death, and 0.45 (0.38–0.53) for stillbirth, respectively. The protective effect of gestational hypertension against perinatal death became weaker over advancing gestational age; the aHRs in very preterm (<32 weeks), mild preterm (32–36 weeks) and term (37+ weeks) births were 0.29, 0.48 and 0.76, respectively. The largest risk reductions in neonatal mortality were observed for infections and immaturity-related conditions. Conclusions Gestational hypertension appears to be beneficial for fetal survival in twin pregnancies, especially in those ending more prematurely or for deaths due to infections and immaturity-related conditions. Prospective studies are required to rule out the possibility of unmeasured confounders. PMID:24733364

The perinatal mortality review meeting that takes place within the hospital following a stillbirth or neonatal death enables clinicians to learn vital lessons to improve care for women and their families for the future. Recent evidence suggests that parents are unaware that a formal review following the death of their baby takes place. Many would welcome the opportunity to feedback into the meeting itself. Parental involvement in the perinatal mortality review meeting has the potential to improve patient satisfaction, drive improvements in patient safety and promote an open culture within healthcare. Yet evidence on the feasibility of involving bereaved parents in the review process is lacking. This paper describes the protocol for the Parents' Active Role and Engangement iN the review of their Stillbirth/perinatal death study (PARENTS 2) , whereby healthcare professionals' and stakeholders' perceptions of parental involvement will be investigated, and parental involvement in the perinatal mortality review will be piloted and evaluated at two hospitals. We will investigate perceptions of parental involvement in the perinatal mortality review process by conducting four focus groups. A three-round modified Delphi technique will be employed to gain a consensus on principles of parental involvement in the perinatal mortality review process. We will use three sequential rounds, including a national consensus meeting workshop with experts in stillbirth, neonatal death and bereavement care, and a two-stage anonymous online questionnaire. We will pilot a new perinatal mortality review process with parental involvement over a 6-month study period. The impact of the new process will be evaluated by assessing parents' experiences of their care and parents' and staff perceptions of their involvement in the process by conducting further focus groups and using a Parent Generated Index questionnaire. This study has ethical approval from the UK Health Research Authority. We will disseminate the findings through national and international conferences and international peer-reviewed journals. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Despite the recent increase in preterm birth in the United States, trends in preterm birth subtypes have not been adequately examined. We examined trends in preterm birth among singletons following ruptured membranes, medical indications, and spontaneous preterm birth and evaluated the impact of these trends on perinatal mortality. A population-based, retrospective cohort study comprising 46,375,578 women (16% blacks) who delivered singleton births in the United States, 1989 through 2000, was performed. Rates of preterm birth (< 37 weeks), their subtypes, and associated perinatal mortality (stillbirths at >/= 22 weeks plus neonatal deaths within 28 days), before and after adjustment for potential confounders, were derived from ecological logistic regression models. Preterm birth rates increased by 14% (95% confidence interval 13-15%) among whites from 8.3% to 9.4% and decreased by 15% (95% confidence interval 14-16%) among blacks from 18.5% to 16.2% between 1989 and 2000. Among whites, preterm birth following ruptured membranes declined by 23%, medically indicated preterm birth increased by 55%, and spontaneous preterm birth increased by 3%. Among blacks, preterm birth following ruptured membranes declined by 37%, medically indicated preterm birth increased by 32%, and spontaneous preterm birth decreased by 27%. The largest decline in perinatal mortality among whites was associated with increases in medically indicated preterm birth, whereas the largest decline in perinatal mortality among blacks was associated with declines in preterm birth following ruptured membranes and spontaneous preterm birth. Temporal trends in preterm birth varied substantially based on underlying subtype and maternal race. The recent increase in medically indicated preterm birth was associated with a favorable reduction in perinatal mortality.

Background Training of birth attendants in neonatal resuscitation is likely to reduce birth asphyxia and neonatal mortality. We performed a systematic review and meta-analysis to assess the impact of neonatal resuscitation training (NRT) programme in reducing stillbirths, neonatal mortality, and perinatal mortality Methods We considered studies where any NRT was provided to healthcare personnel involved in delivery process and handling of newborns. We searched MEDLINE, CENTRAL, ERIC and other electronic databases. We also searched ongoing trials and bibliographies of the retrieved articles, and contacted experts for unpublished work. We undertook screening of studies and assessment of risk of bias in duplicates. We performed review according to Cochrane Handbook. We assessed the quality of evidence using the GRADE approach. Results We included 20 trials with 1 653 805 births in this meta-analysis. The meta-analysis of NRT versus control shows that NRT decreases the risk of all stillbirths by 21% (RR 0.79, 95% CI 0.44 to 1.41), 7-day neonatal mortality by 47% (RR 0.53, 95% CI 0.38 to 0.73), 28-day neonatal mortality by 50% (RR 0.50, 95% CI 0.37 to 0.68) and perinatal mortality by 37% (RR 0.63, 95% CI 0.42 to 0.94). The meta-analysis of pre-NRT versus post-NRT showed that post-NRT decreased the risk of all stillbirths by 12% (RR 0.88, 95% CI 0.83 to 0.94), fresh stillbirths by 26% (RR 0.74, 95% CI 0.61 to 0.90), 1-day neonatal mortality by 42% (RR 0.58, 95% CI 0.42 to 0.82), 7-day neonatal mortality by 18% (RR 0.82, 95% CI 0.73 to 0.93), 28-day neonatal mortality by 14% (RR 0.86, 95% CI 0.65 to 1.13) and perinatal mortality by 18% (RR 0.82, 95% CI 0.74 to 0.91). Conclusions Findings of this review show that implementation of NRT improves neonatal and perinatal mortality. Further good quality randomised controlled trials addressing the role of NRT for improving neonatal and perinatal outcomes may be warranted.

Improvement of perinatal outcome in diabetic pregnant women.

Szilagyi, A; Szabo, I

Obstetrical and perinatal outcomes in newborns of diabetic pregnant women depend on metabolic control and fetal surveillance during pregnancy. The effects of fetal surveillance on perinatal mortality and morbidity was analyzed in diabetic pregnant women with appropriate glucose control in our regional center for diabetes and pregnancy. 480 deliveries complicated by frank or gestational diabetes occurred in our Department in the period of 1988-1999. Perinatal mortality and morbidity, prevalence of premature deliveries, methods of fetal surveillance, options for respiratory distress syndrome (RDS) profilaxis, cesarean section rate, timing of delivery and its indications and occurrence of malformations have been analyzed. It was found that malformation rate and perinatal mortality may be reduced to even lower level than that of in healthy pregnant women by appropriate glucose control and by using the latest methods of intrauterine fetal surveillance including cardiotocography (non stress test and oxytocin challenge test), doppler fetal artery velocimetry and fetal pulse oximetry. Timing of delivery was needed in 35% of the cases with IDDM and 15% of gestational diabetes due to chronic placental insufficiency. If labour induction was needed before the 38 weeks, amniocentesis was performed to test fetal lung maturity. Direct fetal glucocorticoid administration was used to enhance fetal lung maturation in 14 cases. C-section rate was slightly higher than that of in non diabetic pregnant women. Our perinatal morbidity data (macrosomia, hyperbilirubinemia, hypoglycemia, injuries, infections) are comparable with the data from the literature. Although perinatal mortality with the help of thorough fetal surveillance is even better in diabetic pregnant women than in non diabetic patients, future eye should be focused on factors affecting perinatal morbidity, because it is still higher than in newborns of healthy mothers.

Perinatal mortality by gestational week and size at birth in singleton pregnancies at and beyond term: a nationwide population-based cohort study

PubMed Central

2014-01-01

Background Whether gestational age per se increases perinatal mortality in post-term pregnancy is unclear. We aimed at assessing gestational week specific perinatal mortality in small-for-gestational-age (SGA) and non-SGA term and post-term gestations, and specifically to evaluate whether the relation between post-term gestation and perinatal mortality differed before and after ultrasound was introduced as the standard method of gestational age estimation. Methods A population-based cohort study, using data from the Medical Birth Registry of Norway (MBRN), 1967–2006, was designed. Singleton births at 37 through 44 gestational weeks (n = 1 855 682), excluding preeclampsia, diabetes and fetal anomalies, were included. Odds ratios (OR) with 95% confidence intervals (CI) for perinatal mortality and stillbirth in SGA and non-SGA births by gestational week were calculated. Results SGA infants judged post-term by LMP had significantly higher perinatal mortality than post-term non-SGA infants at 40 weeks, independent of time period (highest during 1999–2006 [OR 9.8, 95% CI: 5.7-17.0]). When comparing years before (1967–1986) versus after (1987–2006) ultrasound was introduced, there was no decrease in the excess mortality for post-term SGA versus non-SGA births (ORs from 6.1 [95% CI: 5.2-7.1] to 6.7 [5.2-8.5]), while mortality at 40 weeks decreased significantly (ORs from 4.6, [4.0-5.3] to 3.2 [2.5-3.9]). When assessing stillbirth risk (1999–2006), more than 40% of SGA stillbirths (11/26) judged to be ≥41 weeks by LMP were shifted to lower gestational ages using ultrasound estimation. Conclusions Mortality risk in post-term infants was strongly associated with growth restriction. Such infants may erroneously be judged younger than they are when using ultrasound estimation, so that the routine assessment for fetal wellbeing in the prolonged gestation may be given too late.

Patterns of mortality in public and private hospitals of Addis Ababa, Ethiopia

PubMed Central

2012-01-01

Background Ethiopia is encountering a growing burden of non-communicable diseases along with infectious diseases, perinatal and nutritional problems that have long been considered major problems of public health importance. This retrospective analysis was carried out to examine the mortality patterns from communicable diseases and non communicable diseases in public and private hospitals of Addis Ababa. Methods Approximately 47,153 deaths were captured over eight years (2002–2010) in forty three public and private hospitals of Addis Ababa, Ethiopia. Data collectors (43 hospital clerks) and coordinators (3 nurses) had been extensively trained on how to review hospital death records. Information obtained included: dates of admission and death, age, sex, address, and principal cause of death. Only the diseases responsible for deaths are taken as the cause of death. Cause of death was coded using International Classification of Diseases (ICD-10) and data were double entered. Diseases were classified into: Group I (communicable diseases, maternal conditions and nutritional deficiencies); Group II (non-communicable causes); and Group III (injuries). Percentages, proportional mortality ratios, 95% confidence intervals (CI) and Adjusted odd ratios (OR) were calculated. Results Overall, 59% of the deaths were attributed to Group I diseases, and 31% to Group II diseases and 12% to injuries. Nearly 56% of the males and 68% of the females deaths were due to five leading causes (conditions arising during perinatal period, HIV/AIDS, tuberculosis, cardiovascular diseases and respiratory infections). Significantly larger proportions of females died from Group I (67%) and Group II diseases (32%) compared with males (where the respective proportions were 52% and 30%). Significantly higher proportion of males (17%) than females (6%) were dying from Group III diseases. Deaths due to Group I diseases decreased while those due to Group II diseases increased with age. Overall Group I diseases and HIV/AIDS, tuberculosis and still birth mortality in particular have showed decreasing trend while Group II and III increasing over time. Double burden in mortality was highly observed in the age groups of 15–64 years. Those aged >45 years were dying more likely with non-communicable diseases compared with children. Children aged below 15 years were 16 times more likely to die from communicable, perinatal and nutritional conditions compared with elders. Mortality variation with age has been identified between public and private hospitals. Conclusions The results of the present study shows that, in addition to the common Group I causes of death, emerging group II diseases are contributing to high proportions of mortality in the public and private hospitals of Addis Ababa, Ethiopia. Thus, priority should be given to the prevention and management of conditions arising during perinatal period such as low birth weight and still birth, HIV/AIDS; tuberculosis, respiratory infections, cardiovascular diseases, malignant neoplasm, chronic respiratory diseases and road traffic accident. The planning of health resources and activities should take into account the double burden in mortality due to Group I and Group II diseases. This calls for strengthening approaches towards the control and prevention of non-communicable diseases such as cardiovascular and malignant neoplasm. PMID:23167315

Project Pró-natal: population-based study of perinatal and infant mortality in natal, Northeast Brazil.

The Pró-Natal project is a collaborative initiative that aims to improve maternal and infant health in a deprived community in Natal, Northeast Brazil. To assess the perinatal and infant mortality in this population of 40,000, we have collected over a 2-year period a consecutive series of 39 autopsy examinations on deaths under 1 year of age. During this period there were 2212 live births in the study population. The 14 perinatal deaths are described using the Wrigglesworth classification, and the 25 infant deaths, using a clinicopathological system. The contribution of normally formed stillbirths was small (14%), which probably reflects the underreporting of stillbirths in this community. The most common cause of death in the live births was complications of prematurity (43%). Specific causes (22%) of perinatal deaths were predominantly infections, including one case of congenital syphilis. Perinatal asphyxia was diagnosed in 14%, and there was one case (7%) of a chromosome abnormality. Infant deaths were predominantly due to respiratory (45%) and gastrointestinal infections (28%), with chronic malnutrition as an underlying cause in 80% of cases. Prenatal care could theoretically have prevented three of the perinatal deaths, and a further six deaths could have been avoided by improved management of labor and the immediate neonatal period. Prevention of malnutrition and improved treatment of acute infections would contribute to a reduction in infant mortality in this population. The Pró-Natal project will use these data to design preventative interventions to reduce perinatal and infant mortality in this community.

Clinical and scientific results in perinatal care of pregnancy complicated by insulin dependent diabetes mellitus in Croatia.

Djelmis, J

1998-01-01

At the Department of Obstetrics and Gynecology, Perinatal Unit for Diabetes and Fetal Growth, School of Medicine, Zagreb, perinatal care of pregnancies complicated with insulin dependent diabetes melitus (IDDM), has been performed for more than 36 years. The intention of this review is to show our own results in the management of IDDM pregnancies and the latest clinical advances in perinatal care of such pregnancies. Pregnancy complicated with IDDM is at risk because of numerous maternal, fetal and neonatal complications. Recent advances in medicine, especially in diabetology and perinatology, helps clinician avoid or lessen antenatal or perinatal complications in IDDM pregnancies. The main result of improved perinatal care is that today fetal and neonatal mortality in IDDM pregnancy is almost equal to that of healthy pregnant population. Intensive preconceptual care and optimal regulation of IDDM have resulted not only in decreased perinatal mortality but also in a decreased rate of congenital malformation. Tight glycemia control during pregnancy has a beneficial effect on fetal growth. Intensive control of fetal growth, verification of lung maturation at term by amniocenthesis, and control of fetal oxygenation will result in delivery of a mature eutrophic newborn with the lowest rate of neonatal complications possible. Perinatal mortality of less than 2% in IDDM pregnancy can be obtained by planned delivery between 38 and 39 weeks of gestation by either vaginal route or cesarean section, depending on indications. After delivery, intensive care of the newborn is necessary.

Description of the implementation of local audit meetings and the identified substandard factors, points of special interest, actions for improvement and the opinion of the participating health care providers. Descriptive study. A new organisation and methodology for perinatal mortality audit meetings was introduced in 15 collaborative structures in the northern part of the Netherlands in the period September 2007 to March 2010. During these multidisciplinary audit meetings, cases of perinatal mortality selected by the obstetric collaborative group were discussed in a structured way under the direction of an independent chairman. In total 64 audit meetings were held, in which 677 perinatal health care providers took part at least once, and 112 cases of perinatal death were evaluated. 163 substandard factors were identified. These included : not following the protocol, guideline, standard (31%) or usual care (23%) and insufficient documentation (28%) and communication between health care providers (13%). 442 actions to improve care were reported divided over: 'external collaboration' (15%), 'internal collaboration' (17%), 'practice management' (26%) and 'training and education' (10%). The most valued aspects of the audit meetings were: their multidisciplinary character, the collaborative search for substandard factors, their security, the learning effect and the positive effect on collaboration. Cases of perinatal mortality were discussed in all 15 perinatal collaborative structures in the northern part of the Netherlands. Substandard factors were identified, but further analysis of these factors merits attention. The participants concluded that the multidisciplinary approach and the collaboration during the audit meetings improved the cooperation between perinatal health care providers.

Objective To assess the implementation and first results of a term perinatal internal audit by a standardised method. Design Population-based cohort study. Setting All 90 Dutch hospitals with obstetric/paediatric departments linked to community practices of midwives, general practitioners in their attachment areas, organised in perinatal cooperation groups (PCG). Population The population consisted of 943 registered term perinatal deaths occurring in 2010–2012 with detailed information, including 707 cases with completed audit results. Main outcome measures Participation in the audit, perinatal death classification, identification of substandard factors (SSF), SSF in relation to death, conclusive recommendations for quality improvement in perinatal care and antepartum risk selection at the start of labour. Results After the introduction of the perinatal audit in 2010, all PCGs participated. They organised 645 audit sessions, with an average of 31 healthcare professionals per session. Of all 1102 term perinatal deaths (2.3/1000) data were registered for 86% (943) and standardised anonymised audit results for 64% (707). In 53% of the cases at least one SSF was identified. Non-compliance to guidelines (35%) and deviation from usual professional care (41%) were the most frequent SSF. There was a (very) probable relation between the SSF and perinatal death for 8% of all cases. This declined over the years: from 10% (n=23) in 2010 to 5% (n=10) in 2012 (p=0.060). Simultaneously term perinatal mortality decreased from 2.3 to 2.0/1000 births (p<0.00001). Possibilities for improvement were identified in the organisation of care (35%), guidelines or usual care (19%) and in documentation (15%). More pregnancies were antepartum selected as high risk, 70% in 2010 and 84% in 2012 (p=0.0001). Conclusions The perinatal audit is implemented nationwide in all obstetrical units in the Netherlands in a short time period. It is possible that the audit contributed to the decrease in term perinatal mortality. PMID:25763794

BACKGROUND: Increased use of operative vaginal delivery (i.e., forceps or vacuum application), of which 20% occurs at midpelvic station, has been advocated to reduce the rate of cesarean delivery. We aimed to quantify severe perinatal and maternal morbidity and mortality associated with attempted midpelvic operative vaginal delivery. METHODS: We studied all term singleton deliveries in Canada between 2003 and 2013, by attempted midpelvic operative vaginal or cesarean delivery with labour (with and without prolonged second stage). The primary outcomes were composite severe perinatal morbidity and mortality (e.g., convulsions, assisted ventilation, severe birth trauma and perinatal death), and composite severe maternal morbidity and mortality (e.g., severe postpartum hemorrhage, shock, sepsis, cardiac complications, acute renal failure and death). RESULTS: The study population included 187 234 deliveries. Among women with dystocia and prolonged second stage of labour, midpelvic operative vaginal delivery was associated with higher rates of severe perinatal morbidity and mortality compared with cesarean delivery (forceps, adjusted odds ratio [AOR] 1.81, 95% confidence interval [CI] 1.24 to 2.64; vacuum, AOR 1.81, 95% CI 1.17 to 2.80; sequential instruments, AOR 3.19, 95% CI 1.73 to 5.88), especially with higher rates of severe birth trauma. Rates of severe maternal morbidity and mortality were not significantly different after operative vaginal delivery, although rates of obstetric trauma were higher (forceps, AOR 4.51, 95% CI 4.04 to 5.02; vacuum, AOR 2.70, 95% CI 2.35 to 3.09; sequential instruments, AOR 4.24, 95% CI 3.46 to 5.19). Among women with fetal distress, similar associations were seen for severe birth trauma and obstetric trauma, although vacuum was associated with lower rates of severe maternal morbidity and mortality (AOR 0.52, 95% CI 0.33 to 0.80). Associations tended to be stronger among women without a prolonged second stage. INTERPRETATION: Midpelvic operative vaginal delivery is associated with higher rates of severe birth trauma and obstetric trauma, whereas overall rates of severe perinatal and maternal morbidity and mortality vary by indication and operative instrument.

This study is aimed to identify the risk factors for the development of placenta accreta (PA) and characterize its effect on maternal and perinatal outcomes. This population-based retrospective cohort study included all deliveries at our medical center during the study period. Those with placenta accreta (n = 551) comprised the study group, while the rest of the deliveries (n = 239 089) served as a comparison group. The prevalence of placenta accerta is 0.2%. Women with this complication had higher rates of ≥2 previous CS (p < 0.001), recurrent abortions (p = 0.03), and previous placenta accreta [p < 0.001]. The rates of placenta previa and peripartum hemorrhage necessitating blood transfusion were higher in women with placenta accreta than in the comparison group. PTB before 34 and 37 weeks of gestation was more common among women with placenta accreta (p < 0.01), as was the rate of perinatal mortality (p < 0.001). Placenta accreta was an independent risk factor for perinatal mortality (adj. OR 8.2; 95% CI 6.4-10.4, p < 0.001) and late PTB (adj. OR 1.4; 95% CI 1.1-1.7, p = 0.002). Placenta accreta is an independent risk factor for late PTB and perinatal mortality.

Maternal, perinatal and neonatal mortality remains high in low-income countries. We evaluated community and facility-based interventions to reduce deaths in three districts of Malawi. We evaluated a rural participatory women's group community intervention (CI) and a quality improvement intervention at health centres (FI) via a two-by-two factorial cluster randomized controlled trial. Consenting pregnant women were followed-up to 2 months after birth using key informants. Primary outcomes were maternal, perinatal and neonatal mortality. Clusters were health centre catchment areas assigned using stratified computer-generated randomization. Following exclusions, including non-birthing facilities, 61 clusters were analysed: control (17 clusters, 4912 births), FI (15, 5335), CI (15, 5080) and FI + CI (14, 5249). This trial was registered as International Standard Randomised Controlled Trial [ISRCTN18073903]. Outcomes for 14,576 and 20,576 births were recorded during baseline (June 2007-September 2008) and intervention (October 2008-December 2010) periods. For control, FI, CI and FI + CI clusters neonatal mortality rates were 34.0, 28.3, 29.9 and 27.0 neonatal deaths per 1000 live births and perinatal mortality rates were 56.2, 55.1, 48.0 and 48.4 per 1000 births, during the intervention period. Adjusting for clustering and stratification, the neonatal mortality rate was 22% lower in FI + CI than control clusters (OR = 0.78, 95% CI 0.60-1.01), and the perinatal mortality rate was 16% lower in CI clusters (OR = 0.84, 95% CI 0.72-0.97). We did not observe any intervention effects on maternal mortality. Despite implementation problems, a combined community and facility approach using participatory women's groups and quality improvement at health centres reduced newborn mortality in rural Malawi.

Background Maternal, perinatal and neonatal mortality remains high in low-income countries. We evaluated community and facility-based interventions to reduce deaths in three districts of Malawi. Methods We evaluated a rural participatory women’s group community intervention (CI) and a quality improvement intervention at health centres (FI) via a two-by-two factorial cluster randomized controlled trial. Consenting pregnant women were followed-up to 2 months after birth using key informants. Primary outcomes were maternal, perinatal and neonatal mortality. Clusters were health centre catchment areas assigned using stratified computer-generated randomization. Following exclusions, including non-birthing facilities, 61 clusters were analysed: control (17 clusters, 4912 births), FI (15, 5335), CI (15, 5080) and FI + CI (14, 5249). This trial was registered as International Standard Randomised Controlled Trial [ISRCTN18073903]. Outcomes for 14 576 and 20 576 births were recorded during baseline (June 2007–September 2008) and intervention (October 2008–December 2010) periods. Results For control, FI, CI and FI + CI clusters neonatal mortality rates were 34.0, 28.3, 29.9 and 27.0 neonatal deaths per 1000 live births and perinatal mortality rates were 56.2, 55.1, 48.0 and 48.4 per 1000 births, during the intervention period. Adjusting for clustering and stratification, the neonatal mortality rate was 22% lower in FI + CI than control clusters (OR = 0.78, 95% CI 0.60–1.01), and the perinatal mortality rate was 16% lower in CI clusters (OR = 0.84, 95% CI 0.72–0.97). We did not observe any intervention effects on maternal mortality. Conclusions Despite implementation problems, a combined community and facility approach using participatory women’s groups and quality improvement at health centres reduced newborn mortality in rural Malawi.

Aboriginal populations are at substantially higher risks of adverse birth outcomes, perinatal and infant mortality than their non-Aboriginal counterparts even in developed countries including Australia, U.S. and Canada. There is a lack of data on recent trends in Canada. We conducted a population-based retrospective cohort study (n = 254,410) using the linked vital events registry databases for singleton births in Quebec 1996-2010. Aboriginal (First Nations, Inuit) births were identified by mother tongue, place of residence and Indian Registration System membership. Outcomes included preterm birth, small-for-gestational-age, large-for-gestational-age, low birth weight, high birth weight, stillbirth, neonatal death, postneonatal death, perinatal death and infant death. Perinatal and infant mortality rates were 1.47 and 1.80 times higher in First Nations (10.1 and 7.3 per 1000, respectively), and 2.37 and 4.46 times higher in Inuit (16.3 and 18.1 per 1000, respectively) relative to non-Aboriginal (6.9 and 4.1 per 1000, respectively) births (all p<0.001). Compared to non-Aboriginal births, preterm birth rates were persistently (1.7-1.8 times) higher in Inuit, large-for-gestational-age birth rates were persistently (2.7-3.0 times) higher in First Nations births over the study period. Between 1996-2000 and 2006-2010, as compared to non-Aboriginal infants, the relative risk disparities increased for infant mortality (from 4.10 to 5.19 times) in Inuit, and for postneonatal mortality in Inuit (from 6.97 to 12.33 times) or First Nations (from 3.76 to 4.25 times) infants. Adjusting for maternal characteristics (age, marital status, parity, education and rural vs. urban residence) attenuated the risk differences, but significantly elevated risks remained in both Inuit and First Nations births for the risks of perinatal mortality (1.70 and 1.28 times, respectively), infant mortality (3.66 and 1.47 times, respectively) and postneonatal mortality (6.01 and 2.28 times, respectively) in Inuit and First Nations infants (all p<0.001). Aboriginal vs. non-Aboriginal disparities in adverse birth outcomes, perinatal and infant mortality are persistent or worsening over the recent decade in Quebec, strongly suggesting the needs for interventions to improve perinatal and infant health in Aboriginal populations, and for monitoring the trends in other regions in Canada.

The perinatal mortality rate in a large U. S. study was 139 per 1,000 births for twins and 33 per 1,000 for singletons. Sixteen per cent of the twin deaths were due to amniotic fluid infections, 11 per cent to premature rupture of the membranes, 8 per cent to the monovular twin transfusion syndrome, 8 per cent to large placental infarcts, 7 per cent to congenital anomalies, and the rest to over 20 other disorders. The perinatal mortality rate for monozygotic twins was 2.7 times that for dizygotic twins, mainly due to more amniotic fluid infections, congenital anomalies, and the twin transfusion syndrome in the monozygotic pairs. To study the role of poor maternal nutrition on twins, a similar study of perinatal mortality rates was undertaken in Addis Ababa, Ethiopia. Addis Ababa twins had 2.5 times the mortality rate of U. S. twins, mainly due to a higher frequency of amniotic fluid infections, abruptio placentae, cord accidents, obstructed labors, congenital syphillis, and the twin transfusion syndrome in the Ethiopians.

[Can implementation of intensified perinatal survey be effective in improving the quality of perinatal care?].

Intensive scientific research and rapid technical progress have influenced the rapid fall in term newborn mortality. At the same time new problems have arisen such as saving the lives of infants with low and very low birth weight. Solving these problems needs reorganization of perinatal care, better equipment, especially in reference units and in outpatient clinics, as well as more intensive staff training. to obtain information whether implementation of intensified perinatal survey of fetus and newborn mortality can improve the quality of perinatal care in Poland. Implementation of the survey based on Central Statistics Office (GUS) data, Ministry of Health MZ-29 section X Document and the author's own studies. In the year 2008 newborn with birth weight less than 2500 g, constituted 6,06% liveborn infants, newborn weighing from 1000 to 2499 g - 5%, those with weight from 500 to 999 g - 0.51% of all live born infants. These figures differ according to voivodeship. The intensive survey concerning birth weight and perinatal mortality indeces in voivodeshipPoland, as well as in individual voivodeships, showed differences between data from the Central Statistics Office and data from the Ministry of Health MZ-29 document. This may be due to different methods of registrating newborn deaths eg. newborns transfered in the first weekoflife from the maternity ward to intensive care neonatal ward or to other specialistic departaments. Another reason for the difference may be discharge of the newborn data according to the place of birth or the mother's place of permanent domicile registration. This causes disturbances in flow of infomation resulting in ineffective analysis of perinatal mortality and of perinatal care evaluation. In the ongoing analysis it was found that in Poland stillbirths occur twice as often as perinatal deaths (4.3 per thousands) stillbirths and 2.15 per thousands perinatal deaths), with significant differences between voivodeships. This makes it obligatory to conduct medical audit which is a form of specialistic supervision. It is probable that higher number of stillbirths and premature births may be caused by late start of perinatal care in pregnancy. In primary health care, insufficient objective parameters are investigated which lead to assessment of the quality of perinatal care. Correct filling up of the pregnancy chart could improve the quality of the management of prophylactic procedures leading to a fall in the number of premature births and stillbirths. This would also lead to a reduction of costs associated with life saving procedures and improving the quality of life in newborns with low and extremly low birth weight. 1. The survey of fetal and newborn perinatal mortality of fetuses and newborn should be the base for elaborating the perinatal care programme as well as the main source of data for medical audit. This is the instrument for evaluation of the three level perinatal care. It also serves to assess the effectivness of diagnostic and therapeutic recommendations and the programme of active prevention. 2. In order to obtain effectivness in functioning of the three step perinatal care within the framework of the National Health Programme the following steps are needed: - urgent elaboration of new or improved medical documentation which will become obligatory, - implementation of educational programmes and training of teachers. 3. Implementation of medical audit, carried out periodically at all three levels of perinatal care.

Perinatal and infant mortality during the year 1985 was analyzed through a prospective study conducted in 12 Anganwadis (total population of 13,054) located in slum areas of India's Jabalpur city. Overall, the infant mortality rate was 128.7/1000 live births and the perinatal mortality rate was 88.5/1000 live births. 58.5% of deaths occurred in the neonatal period. Causes of neonatal deaths included prematurity, respiratory distress syndrome, birth asphyxia, septicemia, and neonatal tetanus. Postneonatal deaths were largely attributable to dehydration from diarrhea, bronchopneumonia, malnutrition, and infectious diseases. All mortality rates were significantly higher in Muslims than among Hindus. Muslims accounted for 28% of the study population, but contributed 63% of stillbirths and 55% of total infant deaths. This phenomenon appears attributable to the large family size among Muslims coupled with inadequate maternal-child health care. The national neonatal and postneonatal mortality rates are 88/1000 and 52/1000, respectively. The fact that the neonatal mortality rate in the study area was slightly lower than the national average may reflect the impact of ICDS services.

During the first 12 years of operation the perinatal mortality rate in Paisley Maternity Hospital fell steadily from 27 per 1,000 in 1970 to 10 per 1,000 in 1981. During this period the nulliparous birth rate remained constant, but the parous birth rate fell. Improved survival of premature babies, falling numbers of babies with neural tube defects and reduction in intrapartum asphyxia are identified as responsible for this fall. Unexplained intra-uterine death remains an unsolved problem.

To estimate birth population-based perinatal-neonatal mortality and preterm rate in China from a regional survey in 2010. Data of total births in 2010 obtained from 151 level I-III hospitals in Huai'an, Jiangsu, were prospectively collected and analyzed. From 61,227 birth registries (including 60,986 live births and 241 stillbirths), we derive a birth rate of 11.3‰ (of 5.4 million regional population), a male-to-female ratio of 116:100 and valid data from 60,615 newborns. Mean birth weight (BW) was 3441 ± 491 g with 13.6% macrosomia. Low BW was 2.8% (1691/60,372) with 8.83% mortality. Preterm rate was 3.72% (2239/60,264) with 7.61% mortality. Cesarean section rate was 52.9% (31,964/60,445), multiple pregnancy 1.8% (1088/60,567) and birth defects 6.7‰ (411/61,227). There were 97.4% healthy newborns and 2.2% (1298) requiring hospitalized after birth. The perinatal mortality was 7.7‰ (471/61,227, including 241 stillbirths, 230 early neonatal deaths). The neonatal mortality was 4.4‰ (269/60,986). The main causes of neonatal death were birth asphyxia (24.5%), respiratory diseases (21.5%), prematurity related organ dysfunction (18.5%) and congenital anomalies (7.7%), whereas incidence of congenital heart disease and respiratory distress syndrome was 8.6‰ and 6.1‰, respectively. This regional birth population-based data file contains low perinatal-neonatal mortality rates, associated with low proportion of LBW and preterm births, and incidences of major neonatal disease, by which we estimate, in a nationwide perspective, in 16 million annual births, preterm births should be around 800,000, perinatal and neonatal mortality may be 128,000-144,000 and 80,000-96,000, respectively, along with 100,000 respiratory distress syndrome.

The aims of this study were to (1) estimate the perinatal (birth to 24 h) and postnatal (∼24 h to the mean weaning age of 13 wk) mortality risk in pasture-based dairy calves until weaning, and (2) identify associated risk factors in the 2015 calving season. A prospective survey of 32 seasonal calving dairy farms was undertaken. Farmers recorded (daily) the number and sex of the calves alive or dead in the paddocks where cows calved. All daily animal movements in and out of the calf rearing facilities, including death and euthanasia, and the identification of the animals (if applicable) were recorded, and a survey of the farm management practices was undertaken. Individual and farm-level risk factors for perinatal mortality were modeled separately using generalized logistic mixed models with a random effect fitted for herd. Postnatal mortality incidence risk was calculated using time at risk for each calf from 24 h of age, collapsed into weeks, and multiplying the incidence risk by the mean weaning age of the study population. Farm-level risk factors contributing to postnatal mortality in the first week of life were assessed using a multivariable logistic mixed regression model. The mean perinatal mortality risk was 5.7% (95% confidence interval 5.4 to 6.1%) with a range from 2.2 to 8.6% (18,437 calves, 30 farms). Perinatal calf mortality was greater for male relative to female calves (odds ratio 1.39; 95% confidence interval 1.22 to 1.59), calves born in the first week of the calving period in comparison to wk 2 to 11 (odds ratio 0.32 to 0.66), and those born on days with greater rainfall (odds ratio 1.01 per 1 mm increase; 95% confidence interval 1.00 to 1.02). At the farm level, perinatal mortality increased for every extra week of calving period length (odds ratio 1.12; 95% confidence interval 1.06 to 1.17). The mean postnatal mortality risk was 4.1% (95% confidence interval 3.6 to 4.6%) with a range of 0 to 11% between farms. Farm-level risk factors contributing to mortality in the first week of life included farmer-reported disease problems in calves (odds ratio 2.2; 95% confidence interval 1.62 to 2.96), or calves hand-fed colostrum in the first 12 h of life (odds ratio 1.66; 95% confidence interval 1.26 to 2.19), which was assumed to be associated with poor colostrum quality and bacterial contamination. Regional differences were also observed in both perinatal and postnatal mortality risks, indicating that weather conditions, herd size, and management variations contribute to mortality incidence. In summary, the mortality risk of perinatal calves and postnatal calves until weaning on pasture-based farms is comparable with data published from other dairying systems despite the notable management differences. Several risk factors were identified that could be managed to reduce mortality incidence of dairy calves. Copyright © 2017 American Dairy Science Association. Published by Elsevier Inc.

Background Sepsis is a leading cause of perinatal death in developing countries. Vaginal organisms acquired during labor play a significant role. Prior studies suggest that chlorhexidine wiping of the maternal vagina during labor and of the neonate may reduce peripartum infections. Methods We performed a placebo-controlled, randomized trial of chlorhexidine vaginal and neonatal wipes to reduce neonatal sepsis and mortality in three hospitals in Pakistan. The primary study outcome was a composite of neonatal sepsis or 7-day perinatal mortality. Findings From 2005 to 2008, 5,008 laboring women and their neonates were randomized to receive either chlorhexidine wipes (n = 2,505) or wipes with a saline placebo (n = 2,503). The primary outcome was similar in the chlorhexidine and control groups, (3.1% vs. 3.4%; RR 0.91, 95% CI 0.67, 1.24), as was the composite rate of neonatal sepsis or 28-day perinatal mortality, (3.8% vs. 3.9%, RR 0.96, 95% CI 0.73, 1.27). At day 7, the chlorhexidine group had a lower rate of neonatal skin infection. (3.3 vs. 8.2%, p<0.0001) With the exception of less frequent 7-day hospitalization in the chlorhexidine group, there were no significant differences in maternal outcomes between the groups. Interpretation This trial provides evidence that the use of maternal chlorhexidine vaginal wipes during labor and neonatal chlorhexidine wipes does not reduce maternal and perinatal mortality or neonatal sepsis. The finding of reduced superficial skin infections on day 7 without change in sepsis or mortality suggests that this difference, although statistically significant, may not be of major importance.

We describe adverse pregnancy outcomes, including congenital anomalies, fetal, neonatal, and infant mortality among a Missouri population of low-income, rural mothers who participated in two randomized smoking cessation trials. In the Baby BEEP (BB) trial, 695 rural women were recruited from 21 WIC clinics with 650 women's pregnancy outcomes known (93.5% retention rate). Following the BB trial, 298 women who had a live infant after November 2004 were recruited again into and completed the Baby Beep for Kids (BBK) trial. Simple statistics describing the population and perinatal and postneonatal mortality rates were calculated. Of the adverse pregnancy outcomes (n = 79), 29% were spontaneous abortions of less than 20 weeks' gestation, 23% were premature births, and 49% were identified birth defects. The perinatal mortality rate was 15.9 per 1000 births (BB study) compared with 8.6 per 1000 births (state of Missouri) and 8.5 per 1000 births (United States). The postneonatal infant mortality rate was 13.4 per 1000 live births (BBK) compared with 2.1 per 1000 live births (United States). The health disparity in this population of impoverished, rural, pregnant women who smoke, particularly in regard to perinatal and infant deaths, warrants attention.

Maternal care receptivity and its relation to perinatal and neonatal mortality. A rural study.

Bhardwaj, N; Hasan, S B; Zaheer, M

1995-04-01

A longitudinal study was conducted on 212 pregnant women from May 1987 to April 1988. Maternal Care Receptivity (MCR) "an innovative approach" was adopted for the assessment of maternal care services provided to pregnant mothers at their door steps. During follow-up, scores were allotted to each of the services rendered and antenatal status of pregnant women. Depending on the score--MCR was classified as high (11 to 8), moderate (7 to 4) or poor (3 to 0). Perinatal and neonatal deaths were recorded and an inverse relationship between MCR and perinatal and mortalities was observed (z = 5.46, p < 0.0001). Significantly, no perinatal or neonatal deaths occurred in women with high MCR. One of the most important cause of high PNMR and neonatal mortality rate in developing countries is poor MCR, i.e., under utilization of even the existing maternal health services. The main reasons for this under utilization appear to be poverty, illiteracy, ignorance and lack of faith in modern medicine.

To assess the implementation and first results of a term perinatal internal audit by a standardised method. Population-based cohort study. All 90 Dutch hospitals with obstetric/paediatric departments linked to community practices of midwives, general practitioners in their attachment areas, organised in perinatal cooperation groups (PCG). The population consisted of 943 registered term perinatal deaths occurring in 2010-2012 with detailed information, including 707 cases with completed audit results. Participation in the audit, perinatal death classification, identification of substandard factors (SSF), SSF in relation to death, conclusive recommendations for quality improvement in perinatal care and antepartum risk selection at the start of labour. After the introduction of the perinatal audit in 2010, all PCGs participated. They organised 645 audit sessions, with an average of 31 healthcare professionals per session. Of all 1102 term perinatal deaths (2.3/1000) data were registered for 86% (943) and standardised anonymised audit results for 64% (707). In 53% of the cases at least one SSF was identified. Non-compliance to guidelines (35%) and deviation from usual professional care (41%) were the most frequent SSF. There was a (very) probable relation between the SSF and perinatal death for 8% of all cases. This declined over the years: from 10% (n=23) in 2010 to 5% (n=10) in 2012 (p=0.060). Simultaneously term perinatal mortality decreased from 2.3 to 2.0/1000 births (p<0.00001). Possibilities for improvement were identified in the organisation of care (35%), guidelines or usual care (19%) and in documentation (15%). More pregnancies were antepartum selected as high risk, 70% in 2010 and 84% in 2012 (p=0.0001). The perinatal audit is implemented nationwide in all obstetrical units in the Netherlands in a short time period. It is possible that the audit contributed to the decrease in term perinatal mortality. Published by the BMJ Publishing Group Limited.

It considers the relationships of both biological and socio-economic factors to perinatal mortality....[Results show a] lack of association with any measure of socio-economic status.... Our study has confirmed that survival of the perinatal period is separately related to both maternal age and primiparity. Once maternal age is taken into account, high parity shows no evidence of decreasing survival chances." excerpt

Objective To assess the effectiveness of strategies incorporating training and support of traditional birth attendants on the outcomes of perinatal, neonatal, and maternal death in developing countries. Design Systematic review with meta-analysis. Data sources Medline, Embase, the Allied and Complementary Medicine database, British Nursing Index, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, BioMed Central, PsycINFO, Latin American and Caribbean Health Sciences Literature database, African Index Medicus, Web of Science, Reproductive Health Library, and Science Citation Index (from inception to April 2011), without language restrictions. Search terms were “birth attend*”, “traditional midwife”, “lay birth attendant”, “dais”, and “comadronas”. Review methods We selected randomised and non-randomised controlled studies with outcomes of perinatal, neonatal, and maternal mortality. Two independent reviewers undertook data extraction. We pooled relative risks separately for the randomised and non-randomised controlled studies, using a random effects model. Results We identified six cluster randomised controlled trials (n=138 549) and seven non-randomised controlled studies (n=72 225) that investigated strategies incorporating training and support of traditional birth attendants. All six randomised controlled trials found a reduction in adverse perinatal outcomes; our meta-analysis showed significant reductions in perinatal death (relative risk 0.76, 95% confidence interval 0.64 to 0.88, P<0.001; number needed to treat 35, 24 to 70) and neonatal death (0.79, 0.69 to 0.88, P<0.001; 98, 66 to 170). Meta-analysis of the non-randomised studies also showed a significant reduction in perinatal mortality (0.70, 0.57 to 0.84, p<0.001; 48, 32 to 96) and neonatal mortality (0.61, 0.48 to 0.75, P<0.001; 96, 65 to 168). Six studies reported on maternal mortality and our meta-analysis showed a non-significant reduction (three randomised trials, relative risk 0.79, 0.53 to 1.05, P=0.12; three non-randomised studies, 0.80, 0.44 to 1.15, P=0.26). Conclusion Perinatal and neonatal deaths are significantly reduced with strategies incorporating training and support of traditional birth attendants. PMID:22134967

To assess the effectiveness of strategies incorporating training and support of traditional birth attendants on the outcomes of perinatal, neonatal, and maternal death in developing countries. Systematic review with meta-analysis. Medline, Embase, the Allied and Complementary Medicine database, British Nursing Index, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, BioMed Central, PsycINFO, Latin American and Caribbean Health Sciences Literature database, African Index Medicus, Web of Science, Reproductive Health Library, and Science Citation Index (from inception to April 2011), without language restrictions. Search terms were "birth attend*", "traditional midwife", "lay birth attendant", "dais", and "comadronas". Review methods We selected randomised and non-randomised controlled studies with outcomes of perinatal, neonatal, and maternal mortality. Two independent reviewers undertook data extraction. We pooled relative risks separately for the randomised and non-randomised controlled studies, using a random effects model. We identified six cluster randomised controlled trials (n=138 549) and seven non-randomised controlled studies (n=72 225) that investigated strategies incorporating training and support of traditional birth attendants. All six randomised controlled trials found a reduction in adverse perinatal outcomes; our meta-analysis showed significant reductions in perinatal death (relative risk 0.76, 95% confidence interval 0.64 to 0.88, P<0.001; number needed to treat 35, 24 to 70) and neonatal death (0.79, 0.69 to 0.88, P<0.001; 98, 66 to 170). Meta-analysis of the non-randomised studies also showed a significant reduction in perinatal mortality (0.70, 0.57 to 0.84, p<0.001; 48, 32 to 96) and neonatal mortality (0.61, 0.48 to 0.75, P<0.001; 96, 65 to 168). Six studies reported on maternal mortality and our meta-analysis showed a non-significant reduction (three randomised trials, relative risk 0.79, 0.53 to 1.05, P=0.12; three non-randomised studies, 0.80, 0.44 to 1.15, P=0.26). Perinatal and neonatal deaths are significantly reduced with strategies incorporating training and support of traditional birth attendants.

Background: Placenta previa, a major cause of obstetric hemorrhage, is potentially life-threatening to the mother and frequently results in high perinatal morbidity and mortality. Methodology: This is a retrospective study of all cases of placenta previa managed at the University of Ilorin Teaching Hospital over a 5-year from January 2011 to December 2015. A pro forma template was used to harvest information from case notes of patients involved in the study. Results: There were a total of 10,250 deliveries over the 5-year study and 164 cases of placenta previa were managed during this period; giving an incidence of 1.6% of the total deliveries. Of these patients, 65.9% were unbooked while 34.1% were booked. 110 (67%) were above 30 years of age and 51.2% were grand multiparous women. The majority (81.7%) of the patients belonged to the low socioeconomic class. Painless vaginal bleeding (62.2%), intrapartum hemorrhage (22.6%), and abnormal lie presentation (8.5%) were the most common mode of presentation. Vaginal delivery occurred in (29.3%) of patients while 70. 7% were delivered through cesarean section. There was a significant association between patients’ age, parity, booking status, and types of placenta previa (P < 0.05). Similarly, there was a significant association between gestational age at delivery, mode of delivery, intraoperative blood loss, and birth weight at delivery and types of placenta previa (P < 0.05). Perinatal mortality was 12.2%, 15.6% of babies had severe birth asphyxia, and there was no maternal mortality. Conclusion: From this study, the risk factors for placenta previa are advanced maternal age above 35 years, grand multiparity, and booking status. Early recognition, appropriate referral of these patients and availability of ultrasound facilities, blood transfusion facilities, improvement in neonatal facilities and trained personnel will go a long way in reducing the perinatal mortality from placenta previa.

Clinical studies about the necessity of standard obstetric interventions raise questions, making refusal by pregnant women of treatment a legitimate choice. The present study was aimed at characterising patients refusing medical treatment during pregnancy and delivery, and to examine whether refusal of treatment in obstetrics is associated with adverse perinatal outcome. A population-based study, comparing patients who refused (1898) and did not refuse (164,064) medical intervention during pregnancy and delivery, was conducted. Deliveries occurred between the years 1988 and 2002 in a tertiary medical centre. Patients refusing medical intervention tended to be older (30.5 +/- 5.0 vs. 28.4 +/- 5.9, p < 0.001) and of higher parity (above parity 5: 52.5% vs. 32.4%; parity 1: 10.2% vs. 20.0%; p < 0.001) than the controls. Parturients refusing medical treatment experienced significantly higher rates of adverse perinatal outcome including low Apgar scores (less than 7, in 1 and 5 min: 12.4% vs. 4.4%, p < 0.001 and 1.9% vs. 0.6%, p < 0.001, respectively). Moreover, higher rates of perinatal mortality in general and intra-partum death, in particular, were documented among women refusing medical treatment (3.3% vs. 1.5%, p < 0.001; 0.8% vs. 0.1%, p < 0.001). When using a multiple logistic regression model of risk factors for perinatal mortality, refuse of treatment was an independent risk factor for perinatal mortality (OR = 1.5; 95% CI = 1.1-2.0; p = 0.010). Patients refusing a medically indicated intervention have higher rates of pregnancy- and labour- related complications. Refusal of treatment is an independent risk factor for perinatal mortality.

To determine if the rates of pregnancy complications, preterm birth, small for gestational age, perinatal mortality, and serious neonatal morbidity are higher among mothers aged 35-39 years or 40 years or older, compared with mothers 20-24 years. We performed a population-based study of all women in Nova Scotia, Canada, who delivered a singleton fetus between 1988 and 2002 (N = 157,445). Family income of women who delivered between 1988 and 1995 was obtained through a confidential linkage with tax records (n = 76,300). The primary outcome was perinatal death (excluding congenital anomalies) or serious neonatal morbidity. Analysis was based on logistic models. Older women were more likely to be married, affluent, weigh 70 kg or more, attend prenatal classes, and have a bad obstetric history but less likely to be nulliparous and to smoke. They were more likely to have hypertension, diabetes mellitus, placental abruption, or placenta previa. Preterm birth and small-for-gestational age rates were also higher; compared with women aged 20-24 years, adjusted rate ratios for preterm birth among women aged 35-39 years and 40 years or older were 1.61 (95% confidence interval [CI] 1.42-1.82; P < .001) and 1.80 (95% CI 1.37-2.36; P < .001), respectively. Adjusted rate ratios for perinatal mortality/morbidity were 1.46 (95% CI 1.11-1.92; P = .007) among women 35-39 years and 1.95 (95% CI 1.13-3.35; P = .02) among women 40 years or older. Perinatal mortality rates were low at all ages, especially in recent years. Older maternal age is associated with relatively higher risks of perinatal mortality/morbidity, although the absolute rate of such outcomes is low.

Background Continuum of care has the potential to improve maternal, newborn, and child health (MNCH) by ensuring care for mothers and children. Continuum of care in MNCH is widely accepted as comprising sequential time (from pre-pregnancy to motherhood and childhood) and space dimensions (from community-family care to clinical care). However, it is unclear which linkages of care could have a greater effect on MNCH outcomes. The objective of the present study is to assess the effectiveness of different continuum of care linkages for reducing neonatal, perinatal, and maternal mortality in low- and middle-income countries. Methods We searched for randomized and quasi-randomized controlled trials that addressed two or more linkages of continuum of care and attempted to increase mothers’ uptake of antenatal care, skilled birth attendance, and postnatal care. The outcome variables were neonatal, perinatal, and maternal mortality. Results Out of the 7,142 retrieved articles, we selected 19 as eligible for the final analysis. Of these studies, 13 used packages of intervention that linked antenatal care, skilled birth attendance, and postnatal care. One study each used packages that linked antenatal care and skilled birth attendance or skilled birth attendance and postnatal care. Four studies used an intervention package that linked antenatal care and postnatal care. Among the packages that linked antenatal care, skilled birth attendance, and postnatal care, a significant reduction was observed in combined neonatal, perinatal, and maternal mortality risks (RR 0.83; 95% CI 0.77 to 0.89, I2 79%). Furthermore, this linkage reduced combined neonatal, perinatal, and maternal mortality when integrating the continuum of care space dimension (RR 0.85; 95% CI 0.77 to 0.93, I2 81%). Conclusions Our review suggests that continuous uptake of antenatal care, skilled birth attendance, and postnatal care is necessary to improve MNCH outcomes in low- and middle-income countries. The review was conclusive for the reduction of neonatal and perinatal deaths. Although maternal deaths were not significantly reduced, composite measures of all mortality were. Thus, the evidence is sufficient to scale up this intervention package for the improvement of MNCH outcomes. PMID:26422685

Objective To provide perinatal mortality and congenital anomaly rates for babies born to women with type 1 or type 2 diabetes in England, Wales, and Northern Ireland. Design National population based pregnancy cohort. Setting 231 maternity units in England, Wales, and Northern Ireland. Participants 2359 pregnancies to women with type 1 or type 2 diabetes who delivered between 1 March 2002 and 28 February 2003. Main outcome measures Stillbirth rates; perinatal and neonatal mortality; prevalence of congenital anomalies. Results Of 2359 women with diabetes, 652 had type 2 diabetes and 1707 had type 1 diabetes. Women with type 2 diabetes were more likely to come from a Black, Asian, or other ethnic minority group (type 2, 48.8%; type 1, 9.1%) and from a deprived area (type 2, 46.3% in most deprived fifth; type 1, 22.8%). Perinatal mortality in babies of women with diabetes was 31.8/1000 births. Perinatal mortality was comparable in babies of women with type 1 (31.7/1000 births) and type 2 diabetes (32.3/1000) and was nearly four times higher than that in the general maternity population. 141 major congenital anomalies were confirmed in 109 offspring. The prevalence of major congenital anomaly was 46/1000 births in women with diabetes (48/1000 births for type 1 diabetes; 43/1000 for type 2 diabetes), more than double that expected. This increase was driven by anomalies of the nervous system, notably neural tube defects (4.2-fold), and congenital heart disease (3.4-fold). Anomalies in 71/109 (65%) offspring were diagnosed antenatally. Congenital heart disease was diagnosed antenatally in 23/42 (54.8%) offspring; anomalies other than congenital heart disease were diagnosed antenatally in 48/67 (71.6%) offspring. Conclusion Perinatal mortality and prevalence of congenital anomalies are high in the babies of women with type 1 or type 2 diabetes. The rates do not seem to differ between the two types of diabetes. PMID:16782722

To determine the trend of concurrent maternal and perinatal mortality at the Korle-Bu Teaching Hospital (KBTH), Ghana, and to propose measures for its prevention. A retrospective study, from January 1995 to December 2002, of all concurrent maternal and perinatal deaths in which the woman was 28 weeks' gestation or more (or, if gestational age was not known, the baby weighed 1000 g or more) and died either undelivered or in the perinatal period (within 1 week of delivery) at the KBTH. Over the 8-year study period, there was a total of 93 622 deliveries at the KBTH with 108 concurrent maternal and perinatal mortalities, giving a ratio of 115.4 concurrent maternal and perinatal deaths per 100 000 deliveries. More than 80% of the mothers who died had little or no formal education. Of the 108 mothers, 22 died undelivered. The leading cause of death was a medical condition in pregnancy along with eclampsia/gestational hypertension. Of the 86 delivered mothers, the leading cause of concurrent death was a medical condition in pregnancy. Approximately two-thirds (72/108) of the perinatal deaths were stillbirths. Over the study period, there was a rising trend of the obstetric disaster of losing both mother and baby. There is a rising trend of concurrent maternal and perinatal mortality at the KBTH. It is suggested that a regular antenatal clinic be established with both an internist and obstetrician to jointly see and manage women with medical problems. There is a need for improved and adequate resources to improve outcomes for both mother and baby. A waiver of user fees for maternity services may be one way to improve access for needy and at-risk mothers. Concurrent maternal and perinatal death is the latest negative reproductive health index of the deteriorating socioeconomic situation in developing countries and needs to be tackled decisively.

Geographical inequalities in perinatal health and child welfare require attention. To improve the identification, and care, of mothers and young children at risk of adverse health outcomes, the HP4All-2 program was developed. The program consists of three studies, focusing on creating a continuum for risk selection and tailored care pathways from preconception and antenatal care towards 1) postpartum care, 2) early childhood care, as well as 3) interconception care. The program has been implemented in ten municipalities in the Netherlands, aiming to target communities with a relatively disadvantageous position with regard to perinatal and child health outcomes. To delineate the position of the ten participating municipalities, we present municipal and regional differences in the prevalence of perinatal mortality, perinatal morbidity, children living in deprived neighbourhoods, and children living in families on welfare. Data on all singleton births in the Netherlands between 2009 and 2014 were analysed for the prevalence of perinatal mortality and morbidity. In addition, national data on children living in deprived neighbourhoods and children living in families on welfare between 2009 and 2012 were analysed. The prevalence of these outcomes were calculated and ranked for 62 geographical areas, the 50 largest municipalities and the 12 provinces, to determine the position of the municipalities that participate in HP4All-2. Considerable geographical differences were present for all four outcomes. The municipalities that participate in HP4All-2 are among the 25 municipalities with the highest prevalence of perinatal mortality, perinatal morbidity, children living in deprived neighbourhoods, or children in families on welfare. This study illustrates geographical differences in perinatal health and/or child welfare outcomes and demonstrates that the HP4All-2 program targets municipalities with a relative unfavourable position. By targeting these municipalities, the program is expected to contribute most to improving the care for young children and their mothers at risk, and hence to reducing their risks and health inequalities.

Perinatal mortality--a suitable index of health worldwide?

PubMed

Savage, A

1986-11-22

As a result of cultural factors, perinatal mortality may not be the most appropriate measure of health. Comparisons of the health of different countries should not be based on only 1 criterion unless general attitudes are the same. In developed countries, where abortion is widely available, unwanted pregnancies are handled before delivery. In some developing countries in Africa, however, population control may take the form of allowing a newborn to die of starvation, for example. Given this cultural difference, Third World countries rank lowest in perinatal health. It is suggested that mortality and morbidity should be calculated decade by decade before an index is derived. A 20-year old from a developing country, where there is no drug problem and attempted suicide is rare, might receive a higher health rating than his counterpart in developed countries.

To trace and document smaller changes in perinatal survival over time. Prospective observational study, with retrospective analysis. Labor ward and operating theater at Haydom Lutheran Hospital in rural north-central Tanzania. All women giving birth and birth attendants. Helping Babies Breathe (HBB) simulation training on newborn care and resuscitation and some other efforts to improve perinatal outcome. Perinatal survival, including fresh stillbirths and early (24-h) newborn survival. The variable life-adjusted plot and cumulative sum chart revealed a steady improvement in survival over time, after the baseline period. There were some variations throughout the study period, and some of these could be linked to different interventions and events. To our knowledge, this is the first time statistical process control methods have been used to document changes in perinatal mortality over time in a rural Sub-Saharan hospital, showing a steady increase in survival. These methods can be utilized to continuously monitor and describe changes in patient outcomes.

Perinatal interventions and survival in resource-poor settings: which work, which don't, which have the jury out?

Perinatal conditions make the largest contribution to the burden of disease in low-income countries. Although postneonatal mortality rates have declined, stillbirth and early neonatal mortality rates remain high in many countries in Africa and Asia, and there is a concentration of mortality around the time of birth. Our article begins by considering differences in the interpretation of 'intervention' to improve perinatal survival. We identify three types of a single action, a collection of actions delivered in a package and a broader social or system approach. We use this classification to summarise the findings of recent systematic reviews and meta-analyses. After describing the growing evidence base for the effectiveness of community-based perinatal care, we discuss current concerns about integration: of women's and children's health programmes, of community-based and institutional care, and of formal and informal sector human resources. We end with some thoughts on the complexity of choices confronting women and their families in low-income countries, particularly in view of the growth in non-government and private sector healthcare.

Venn, A; Lumley, J

1993-11-01

Pregnancies following a period of infertility are often thought to be at increased risk of adverse outcomes. Between 1982-1990, 1465 births were reported to the Victorian Perinatal Data Collection Unit with a history of infertility. We present some characteristics of these births and compare them with all Victorian births in 1986 (n = 61,253) and Australian and New Zealand IVF and GIFT births 1979-1989 (n = 6,675). Women with a history of infertility were older than other Victorian women but younger than the IVF and GIFT group. Multiple births comprised 9% of the infertility group compared with 1.3% in the general Victorian population and 23.7% of IVF and GIFT births. The incidence of low birth-weight (18.6%) and very low birth-weight (4.2%) was higher than in other Victorian births (5.8% and 1.1% respectively) but lower than in IVF and GIFT births (34.6% and 8.9%). Perinatal mortality in the infertility group (33.4 per 1,000) was higher than in the general population (11.1 per 1,000) and similar to the IVF and GIFT group (34.9 per 1,000). The Caesarean section rate after infertility (41%) was more than double the rate in the rest of the Victorian population (16%), and showed a different pattern of indications. The relative risks of low and very low birth-weight, perinatal mortality and Caesarean delivery remained significantly increased for singletons after adjustment for maternal age and parity.

In Brazil, it was previously reported that in hospital perinatal, neonatal and infant mortality rates are higher for hospitals contracted to the National Public Health System (SUS) compared with non-SUS hospitals. We analyse whether this reflects a compositional effect (selection of patients) or a contextual effect. Population-based cohort study. Belo Horizonte, Brazil, 1999. A total of 36,469 births in 24 hospitals. A multilevel analysis was carried out using information gathered at the individual level on maternal education (used as an indicator of socio-economic status), maternal age, type of pregnancy and delivery, birthweight and sex of the fetus. Perinatal death. Risk factors for perinatal death included male sex (OR = 1.25; 95% CI 1.01-1.55), birthweight of 1500-2500 g (OR = 7.65; 95% CI 5.74-10.20), birthweight of 500-1500 g (OR = 187.54; 95% CI 141.31-248.39), less than 4 years of maternal education (OR = 2.93; 95% CI 1.68-5.10), as well as birth at private-SUS (OR = 2.92; 95% CI 1.87-4.54) or philanthropic-SUS hospitals (OR = 1.81; 95% CI 1.12-2.92). After controlling for individual characteristics, there was still a significant variation in perinatal deaths between hospitals categories. Independent of compositional (or individual) characteristics, hospital factors exert an influence on the risk of perinatal death, primarily hospital category related to SUS. Considering the highest proportion of births in SUS hospitals in Brazil, especially private-SUS hospitals, improving hospital quality of care is an urgent priority for reducing the toll of perinatal and infant mortality, as well as inequalities in these outcomes.

Neonatal mortality reduction in China over past two decades was reported from nationwide sampling surveys, however, how high risk pregnancy affected neonatal outcome is unknown. The objective of this study was to explore relations of pregnancy complications and neonatal outcomes from a regional birth population. In a prospective, cross-sectional survey of complete birth population-based data file from 151 level I-III hospitals in Huai'an region in 2010, pregnancy complications were analyzed for perinatal morbidity and mortality in association with maternal and perinatal characteristics, hospital levels, mode of delivery, newborn birth weight and gestational age, using international definition for birth registry and morbidities. Pregnancy complications were found in 10% of all births, in which more than 70% were delivered at level II and III hospitals associated with higher proportions of fetal and neonatal death, preterm birth, death at delivery and congenital anomalies. High Cesarean section delivery was associated with higher pregnancy complications, and more neonatal critical illnesses. The pregnancy complications related perinatal morbidity and mortality in level III were 2-4 times as high as in level I and II hospitals. By uni- and multi-variate regression analysis, impact of pregnancy complications was along with congenital anomalies and preterm birth, and maternal child-bearing age and school education years contributing to the prevalence. This survey revealed variable links of pregnancy complications to perinatal outcome in association with very high Cesarean section deliveries, which warrants investigation for causal relations between high risk pregnancy and neonatal outcome in this emerging region.

Babies born after midtrimester preterm prelabour rupture of membranes (PPROM) are at risk to develop neonatal pulmonary hypoplasia. Perinatal mortality and morbidity after this complication is high. Oligohydramnios in the midtrimester following PPROM is considered to cause a delay in lung development. Repeated transabdominal amnioinfusion with the objective to alleviate oligohydramnios might prevent this complication and might improve neonatal outcome. Women with PPROM and persisting oligohydramnios between 16 and 24 weeks gestational age will be asked to participate in a multi-centre randomised controlled trial. random allocation to (repeated) abdominal amnioinfusion (intervention) or expectant management (control). The primary outcome is perinatal mortality. Secondary outcomes are lethal pulmonary hypoplasia, non-lethal pulmonary hypoplasia, survival till discharge from NICU, neonatal mortality, chronic lung disease (CLD), number of days ventilatory support, necrotizing enterocolitis (NEC), periventricular leucomalacia (PVL) more than grade I, severe intraventricular hemorrhage (IVH) more than grade II, proven neonatal sepsis, gestational age at delivery, time to delivery, indication for delivery, successful amnioinfusion, placental abruption, cord prolapse, chorioamnionitis, fetal trauma due to puncture. The study will be evaluated according to intention to treat. To show a decrease in perinatal mortality from 70% to 35%, we need to randomise two groups of 28 women (two sided test, β-error 0.2 and α-error 0.05). This study will answer the question if (repeated) abdominal amnioinfusion after midtrimester PPROM with associated oligohydramnios improves perinatal survival and prevents pulmonary hypoplasia and other neonatal morbidities. Moreover, it will assess the risks associated with this procedure. NTR3492 Dutch Trial Register (http://www.trialregister.nl).

We investigated whether patients undergoing vaginal delivery who developed peripartum fever (PPF) had increased rates of other gestational complications. A retrospective study was undertaken comparing pregnancy complications of patients who developed PPF with those who did not. A multivariable logistic regression model was constructed to control for confounders. To avoid ascertainment bias, the year of birth was included in the model. Women who underwent cesarean delivery and those with multiple pregnancies were excluded from the study. During the study period, there were 169,738 singleton vaginal deliveries, and 0.4% of the women suffered from PPF. Hypertensive disorders, induction of labor, dystocia of labor in the second stage, suspected fetal distress, meconium-stained amniotic fluid, postpartum hemorrhage, manual lysis of a retained placenta, and revision of the uterine cavity and cervix were found to be independently associated with PPF by multivariable analysis. Year of birth was found to be a risk factor for fever. Apgar scores lower than 7 at 1 but not 5 minutes were significantly higher in the PPF group. Perinatal mortality rates were significantly higher among women with PPF (6.7% versus 1.3%, odds ratio [OR] = 5.4; 95% confidence interval [CI] 3.9 to 7.3; P < 0.001). Using another multivariable analysis, with perinatal mortality as the outcome variable, PPF was found as an independent risk factor for perinatal mortality (OR = 2.9; 95% CI 1.9 to 4.6; P < 0.001). PPF in women undergoing vaginal deliveries is associated with adverse perinatal outcomes and specifically is an independent risk factor for perinatal mortality.

Perinatal Maternal Mortality in Sickle Cell Anemia: Two Case Reports and Review of the Literature.

As outcomes of patients with sickle cell anemia improve and survival into adulthood with good quality of life and expectation of long-term survival becomes more common, challenges have developed, including issues related to reproduction. Pregnancy is frequently complicated in patients with sickle cell anemia with mortality up to 4.0%. Here we report maternal perinatal mortality in two women with sickle cell anemia who died post-partum due to acute chest syndrome (ACS), caused by bone marrow fat embolism and review the literature pertinent to this subject. Patient A was a 28-year-old woman with sickle cell anemia with multiple complications. At 30 weeks' gestation she developed hemolysis associated with poor placental function necessitating delivery by C-section. The fetus was delivered successfully but she died due to multi organ failure after delivery. Autopsy showed pulmonary and amniotic fluid embolization. Patient B was a 37-year-old woman with uncomplicated sickle cell anemia who presented with pre term labor and crisis, then ACS and fetal distress. The infant was delivered successfully but the patient died after cardiovascular collapse. Autopsy results showed fat and bone marrow embolization as the cause of death. Pregnancy continues to be high risk for patients with sickle cell anemia including those with mild disease. Maternal perinatal mortality could be unpredictable due to serious complications of sickle cell disease. More studies to assess maternal perinatal mortality are needed.

Data of 127,800 Iberian piglets were used to study genetic parameters of mortality at birth at the piglet level. These records proceed from three data sets: 4,987 litter of 2,156 sows of a dam line, 2,768 litter of 817 sows of a complete diallel cross between four Iberian strains and 7,153 litter of 2,113 sows of the Torbiscal composite line. Perinatal mortality was considered as a binary trait, and Bayesian threshold animal models were fitted to separately analyse the three data sets. The posterior means of direct heritability were 0.010, 0.004 and 0.003, and those of maternal heritability were 0.034, 0.011 and 0.014 for dam line, diallel cross and Torbiscal line, respectively. Important effects of litter size and parity order were inferred in the three data sets, of within-breed cross-breeding parameters in the diallel cross and of sex and sow handling in the Torbiscal line Therefore, the inclusion of perinatal mortality in the objective of selection is questionable in this breed and strategies for reducing piglet mortality successful in other breeds should be considered. © 2017 Blackwell Verlag GmbH.

OBJECTIVE: In Sweden, a country with high standards of obstetric care, the high rate of perinatal mortality among children of immigrant women from the Horn of Africa raises the question of whether there is an association between female circumcision and perinatal death. METHOD: To investigate this, we examined a cohort of 63 perinatal deaths of infants born in Sweden over the period 1990-96 to circumcised women. FINDINGS: We found no evidence that female circumcision was related to perinatal death. Obstructed or prolonged labour, caused by scar tissue from circumcision, was not found to have any impact on the number of perinatal deaths. CONCLUSION: The results do not support previous conclusions that genital circumcision is related to perinatal death, regardless of other circumstances, and suggest that other, suboptimal factors contribute to perinatal death among circumcised migrant women.

Perinatal mortality is known to be high in Sub-Saharan Africa. Some women may carry a particularly high risk which would be reflected in a high recurrence risk. We aim to estimate the recurrence risk of perinatal death using data from a hospital in Northern Tanzania. We constructed a cohort study using data from the hospital based KCMC Medical Birth Registry. Women who delivered a singleton for the first time at the hospital between 2000 and 2008 were followed in the registry for subsequent deliveries up to 2010 and 3,909 women were identified with at least one more delivery within the follow-up period. Recurrence risk of perinatal death was estimated in multivariate models analysis while adjusting for confounders and accounting for correlation between births from the same mother. The recurrence risk of perinatal death for women who had lost a previous baby was 9.1%. This amounted to a relative risk of 3.2 (95% CI: 2.2 - 4.7) compared to the much lower risk of 2.8% for women who had had a surviving baby. Recurrence contributed 21.2% (31/146) of perinatal deaths in subsequent pregnancies. Preeclampsia, placental abruption, placenta previa, induced labor, preterm delivery and low birth weight in a previous delivery with a surviving baby were also associated with increased perinatal mortality in the next pregnancy. Some women in Tanzanian who suffer a perinatal loss in one pregnancy are at a particularly high risk of also losing the baby of a subsequent pregnancy. Strategies of perinatal death prevention that target pregnant women who are particularly vulnerable or already have experienced a perinatal loss should be considered in future research.

BACKGROUND: Perinatal complications predict increased risk for morbidity and early mortality. Evidence of perinatal programming of adult mortality raises the question of what mechanisms embed this long-term effect. We tested a hypothesis related to the theory of developmental origins of health and disease: that perinatal complications assessed at birth predict indicators of accelerated aging by midlife. METHODS: Perinatal complications, including both maternal and neonatal complications, were assessed in the Dunedin Multidisciplinary Health and Development Study cohort (N = 1037), a 38-year, prospective longitudinal study of a representative birth cohort. Two aging indicators were assessed at age 38 years, objectively by leukocyte telomere length (TL) and subjectively by perceived facial age. RESULTS: Perinatal complications predicted both leukocyte TL (β = −0.101; 95% confidence interval, −0.169 to −0.033; P = .004) and perceived age (β = 0.097; 95% confidence interval, 0.029 to 0.165; P = .005) by midlife. We repeated analyses with controls for measures of family history and social risk that could predispose to perinatal complications and accelerated aging, and for measures of poor health taken in between birth and the age-38 follow-up. These covariates attenuated, but did not fully explain the associations observed between perinatal complications and aging indicators. CONCLUSIONS: Our findings provide support for early-life developmental programming by linking newborns’ perinatal complications to accelerated aging at midlife. We observed indications of accelerated aging “inside,” as measured by leukocyte TL, an indicator of cellular aging, and “outside,” as measured by perceived age, an indicator of declining tissue integrity. A better understanding of mechanisms underlying perinatal programming of adult aging is needed. PMID:25349321

Introduction Improving maternal and newborn health in low-income settings requires both health service and community action. Previous community initiatives have been predominantly rural, but India is urbanizing. While working to improve health service quality, we tested an intervention in which urban slum-dweller women's groups worked to improve local perinatal health. Methods and Findings A cluster randomized controlled trial in 24 intervention and 24 control settlements covered a population of 283,000. In each intervention cluster, a facilitator supported women's groups through an action learning cycle in which they discussed perinatal experiences, improved their knowledge, and took local action. We monitored births, stillbirths, and neonatal deaths, and interviewed mothers at 6 weeks postpartum. The primary outcomes described perinatal care, maternal morbidity, and extended perinatal mortality. The analysis included 18,197 births over 3 years from 2006 to 2009. We found no differences between trial arms in uptake of antenatal care, reported work, rest, and diet in later pregnancy, institutional delivery, early and exclusive breastfeeding, or care-seeking. The stillbirth rate was non-significantly lower in the intervention arm (odds ratio 0.86, 95% CI 0.60–1.22), and the neonatal mortality rate higher (1.48, 1.06–2.08). The extended perinatal mortality rate did not differ between arms (1.19, 0.90–1.57). We have no evidence that these differences could be explained by the intervention. Conclusions Facilitating urban community groups was feasible, and there was evidence of behaviour change, but we did not see population-level effects on health care or mortality. In cities with multiple sources of health care, but inequitable access to services, community mobilization should be integrated with attempts to deliver services for the poorest and most vulnerable, and with initiatives to improve quality of care in both public and private sectors.

The objective of this study was to critically examine potential artifacts and biases underlying the use of 'customised' standards of birthweight for gestational age (GA). Population-based cohort study. Sweden. A total of 782,303 singletons > or =28 weeks of gestation born in 1992-2001 to Nordic mothers with complete data on birthweight; GA; and maternal age, parity, height, and pre-pregnancy weight. We compared perinatal mortality in four groups of infants based on the following classification of small for gestational age (SGA): non-SGA based on either population-based or customised standards (the reference group), SGA based on the population-based standard only, SGA based on the customised standard only, and SGA according to both standards. We used graphical methods to compare GA-specific birthweight cutoffs for SGA using the two standards and also used logistic regression to control for differences in GA and maternal pre-pregnancy body mass index (BMI) in the four groups. Perinatal mortality, including stillbirth and neonatal death. Customisation led to a large artifactual increase in the proportion of SGA infants born preterm. Adjustment for differences in GA and maternal BMI markedly reduced the excess risk among infants classified as SGA by customised standards only. The large increase in perinatal mortality risk among infants classified as SGA based on customised standards is largely an artifact due to inclusion of more preterm births.

Perinatal pathology: practice suggestions for limited-resource settings.

PubMed

Roberts, Drucilla J

2013-06-01

The practice of perinatal pathology in much of the world suffers, as do all subspecialties of anatomic pathology, from inadequate resources (equipment, consumables, and both professional and technical personnel), from lack of education (not only of the pathologist but also of the clinicians responsible for sending the specimens, and the technicians processing the specimens), and from lack of appropriate government sector support. Perinatal pathology has significant public health-related utility and should be championing its service by providing maternal and fetal/infant mortality and morbidity data to governmental health ministries. It is with this pathologic data that informed decisions can be made on health-related courses of action and allocation of resources. These perinatal pathology data are needed to develop appropriate public health initiatives, specifically toward achieving the Millennium Developmental Goals as the best way to effectively decrease infant and maternal deaths and to determine causes of perinatal mortality and morbidity. The following overview will focus on the utility of perinatal pathology specifically as related to its public health function and will suggest methods to improve its service in resource-poor settings. This article is offered not as a critique of the current practice that most pathologists find themselves working in globally, but to provide suggestions for improving perinatal pathology services, which could be implemented with the limited available resources and manpower most pathology departments currently have. In addition, we offer suggestions for graded improvements ("ramping up") over time.

There are approximately 4 million neonatal deaths and half a million maternal deaths worldwide each year. There is limited evidence from clinical trials to guide the development of effective maternity services in developing countries. We performed a cluster-randomized, controlled trial involving seven subdistricts (talukas) of a rural district in Pakistan. In three talukas randomly assigned to the intervention group, traditional birth attendants were trained and issued disposable delivery kits; Lady Health Workers linked traditional birth attendants with established services and documented processes and outcomes; and obstetrical teams provided outreach clinics for antenatal care. Women in the four control talukas received usual care. The primary outcome measures were perinatal and maternal mortality. Of the estimated number of eligible women in the seven talukas, 10,114 (84.3 percent) were recruited in the three intervention talukas, and 9443 (78.7 percent) in the four control talukas. In the intervention group, 9184 women (90.8 percent) received antenatal care by trained traditional birth attendants, 1634 women (16.2 percent) were seen antenatally at least once by the obstetrical teams, and 8172 safe-delivery kits were used. As compared with the control talukas, the intervention talukas had a cluster-adjusted odds ratio for perinatal death of 0.70 (95 percent confidence interval, 0.59 to 0.82) and for maternal mortality of 0.74 (95 percent confidence interval, 0.45 to 1.23). Training traditional birth attendants and integrating them into an improved health care system were achievable and effective in reducing perinatal mortality. This model could result in large improvements in perinatal and maternal health in developing countries. Copyright 2005 Massachusetts Medical Society.

Midtrimester preterm prelabour rupture of membranes (PPROM): expectant management or amnioinfusion for improving perinatal outcomes (PPROMEXIL – III trial)

PubMed Central

2014-01-01

Background Babies born after midtrimester preterm prelabour rupture of membranes (PPROM) are at risk to develop neonatal pulmonary hypoplasia. Perinatal mortality and morbidity after this complication is high. Oligohydramnios in the midtrimester following PPROM is considered to cause a delay in lung development. Repeated transabdominal amnioinfusion with the objective to alleviate oligohydramnios might prevent this complication and might improve neonatal outcome. Methods/Design Women with PPROM and persisting oligohydramnios between 16 and 24 weeks gestational age will be asked to participate in a multi-centre randomised controlled trial. Intervention: random allocation to (repeated) abdominal amnioinfusion (intervention) or expectant management (control). The primary outcome is perinatal mortality. Secondary outcomes are lethal pulmonary hypoplasia, non-lethal pulmonary hypoplasia, survival till discharge from NICU, neonatal mortality, chronic lung disease (CLD), number of days ventilatory support, necrotizing enterocolitis (NEC), periventricular leucomalacia (PVL) more than grade I, severe intraventricular hemorrhage (IVH) more than grade II, proven neonatal sepsis, gestational age at delivery, time to delivery, indication for delivery, successful amnioinfusion, placental abruption, cord prolapse, chorioamnionitis, fetal trauma due to puncture. The study will be evaluated according to intention to treat. To show a decrease in perinatal mortality from 70% to 35%, we need to randomise two groups of 28 women (two sided test, β-error 0.2 and α-error 0.05). Discussion This study will answer the question if (repeated) abdominal amnioinfusion after midtrimester PPROM with associated oligohydramnios improves perinatal survival and prevents pulmonary hypoplasia and other neonatal morbidities. Moreover, it will assess the risks associated with this procedure. Trial registration NTR3492 Dutch Trial Register (http://www.trialregister.nl). PMID:24708702

To assess the underlying risk factors for perinatal mortality in term born small for gestational age infants. We performed a population based nationwide cohort study in the Netherlands of 465,532 term born infants from January 2010 to January 2013. Logistic regression analyses were performed. Also audit results were studied for detailed care information. We studied 162 small for gestational age infants who died in the perinatal period. Risk factors were: gestational age at 37completed weeks (adjusted Odds Ratio (aOR) 2.6, 95% Confidence Interval (CI) 1.6-4.3), male gender (aOR 1.4, 95% CI 1.01-1.9), South Asian ethnicity (aOR 3.6, 95% CI 1.6-8.4), African (aOR 3.5, 95% CI 1.9-6.5) and other non-Western ethnicity (aOR 1.9, CI 1.2-3.1). At 37 completed weeks gestation audit results showed that 26% of the women smoked, 91% were boys and in all but one case death occurred before birth. In 61% of all deceased SGA infants born at 37 completed weeks gestation referral from primary care by independent midwives to the obstetrician took place because of antepartum death before labor. Gestational age of 37 completed weeks, male gender, South Asian, African or other non-Western ethnicity and smoking are associated with perinatal mortality in SGA infants. These risk factors concern the complete term population starting at 37 weeks or even earlier. Therefore, it is of utmost importance to develop accurate diagnostic tests to screen for SGA before 36 weeks gestation to prevent perinatal mortality at term in SGA infants.

2006-06-01

The purpose of this study was to examine whether women with inherited thrombophilia have an increased risk of developing pregnancy complications. All singleton pregnancies with known inherited thrombophilia were compared to those without inherited thrombophilia for deliveries during the years 2000-2002 in a tertiary medical center. Data regarding inherited thrombophilia (International Classification of Disease 9th revision, Clinical Modification code 286.3) were available from the perinatal database in our center. Women lacking prenatal care were excluded from the analysis. Stratified analysis, using a multiple logistic regression model, was performed to control for confounders. Out of 32,763 singleton deliveries that occurred during the study period, 0.2% (n=57) of the women were diagnosed with inherited thrombophilia. Using a multivariate analysis, with backward elimination, the following conditions were significantly associated with inherited thrombophilia: previous fetal losses [odds ratio (OR)=5.5; 95% confidence interval (CI) 2.9-10.3; P<0.001], recurrent abortions (OR=9.5; 95% CI 5.5-16.3; P<0.001), fertility treatments (OR=3.7; 95% CI 1.3-10.6; P=0.014), and intrauterine growth restriction (OR=7.2; 95% CI 3.4-15; P<0.001). Perinatal mortality was significantly higher in women with inherited thrombophilia than in those without known thrombophilia 5.3% (3/57) versus 0.6% (477/32,763) P=0.017. However, inherited thrombophilia was not found to be an independent risk factor for perinatal mortality (OR=3.05; 95% CI 0.90-10.3; P<0.073) in a multivariate analysis with perinatal mortality as the outcome variable, controlling for recurrent abortions, IUGR, and gestational age. Inherited thrombophilia, associated with previous fetal losses, recurrent abortions, fertility treatments, and intrauterine growth restriction, was not an independent risk factor for perinatal mortality.

Reduced birthweight in short or primiparous mothers: physiological or pathological?

Objective Customisation of birthweight-for-gestational-age standards for maternal characteristics assumes that variation in birth weight as a result of those characteristics is physiological, rather than pathological. Maternal height and parity are among the characteristics widely assumed to be physiological. Our objective was to test that assumption by using an association with perinatal mortality as evidence of a pathological effect. Design Population-based cohort study. Setting Sweden. Population A total of 952 630 singletons born at ≥28 weeks of gestation in the period 1992–2001. Methods We compared perinatal mortality among mothers of short stature (<160 cm) versus those of normal height (≥160 cm), and primiparous versus multiparous mothers, using an internal reference of estimated fetal weight for gestational age. The total effects of maternal height and parity were estimated, as well as the effects of height and parity independent of birthweight (controlled direct effects). All analyses were based on fetuses at risk, using marginal structural Cox models for the estimation of total and controlled direct effects. Main outcome measures Perinatal mortality, stillbirth, and early neonatal mortality. Results The estimated total effect (HR; 95% CI) of short stature on perinatal death among short mothers was 1.2 (95% CI 1.1–1.3) compared with women of normal height; the effect of short stature independent of birthweight (controlled direct effect) was 0.8 (95% CI 0.6–1.0) among small-for-gestational-age (SGA) births, but 1.1 (95% CI 1.0–1.3) among non-SGA births. Similar results were observed for primiparous mothers. Conclusions The effect of maternal short stature or primiparity on perinatal mortality is partly mediated through SGA birth. Thus, birthweight differences resulting from these maternal characteristics appear not only to be physiological, but also to have an important pathological component. PMID:20618317

Mobile phones are increasingly used in health systems in developing countries and innovative technical solutions have great potential to overcome barriers of access to reproductive and child health care. However, despite widespread support for the use of mobile health technologies, evidence for its role in health care is sparse. We aimed to evaluate the association between a mobile phone intervention and perinatal mortality in a resource-limited setting. This study was a pragmatic, cluster-randomized, controlled trial with primary health care facilities in Zanzibar as the unit of randomization. At their first antenatal care visit, 2550 pregnant women (1311 interventions and 1239 controls) who attended antenatal care at selected primary health care facilities were included in this study and followed until 42 days after delivery. Twenty-four primary health care facilities in six districts were randomized to either mobile phone intervention or standard care. The intervention consisted of a mobile phone text message and voucher component. Secondary outcome measures included stillbirth, perinatal mortality, and death of a child within 42 days after birth as a proxy of neonatal mortality. Within the first 42 days of life, 2482 children were born alive, 54 were stillborn, and 36 died. The overall perinatal mortality rate in the study was 27 per 1000 total births. The rate was lower in the intervention clusters, 19 per 1000 births, than in the control clusters, 36 per 1000 births. The intervention was associated with a significant reduction in perinatal mortality with an odds ratio (OR) of 0.50 (95% CI 0.27-0.93). Other secondary outcomes showed an insignificant reduction in stillbirth (OR 0.65, 95% CI 0.34-1.24) and an insignificant reduction in death within the first 42 days of life (OR 0.79, 95% CI 0.36-1.74). Mobile phone applications may contribute to improved health of the newborn and should be considered by policy makers in resource-limited settings.

Women with diabetes in pregnancy have high rates of pregnancy complications. Our aims were to explore trends in the incidence of diabetes in pregnancy and examine whether the risk of serious perinatal outcomes has changed. We performed a population-based cohort study of 1,109,605 women who delivered in Ontario, Canada, between 1 April 1996 and 31 March 2010. We categorized women as gestational diabetes (GDM) (n = 45,384), pregestational diabetes (pre-GDM) (n = 13,278), or no diabetes (n = 1,050,943). The annual age-adjusted rates of diabetes in pregnancy were calculated, and rates of serious perinatal outcomes were compared between groups and by year using Poisson regression. The age-adjusted rate of both GDM (2.7-5.6%, P < 0.001) and pre-GDM (0.7-1.5%, P < 0.001) doubled from 1996 to 2010. The rate of congenital anomalies declined by 23%, whereas the rate of perinatal mortality did not change significantly. However, compared with women with no diabetes, women with pre-GDM and GDM faced an increased risk of congenital anomalies (relative risk 1.86 [95% CI 1.49-2.33] and 1.26 [1.09-1.45], respectively), and perinatal mortality remained elevated in women with pre-GDM (2.33 [1.59-3.43]). The incidence of both GDM and pre-GDM in pregnancy has doubled over the last 14 years, and the overall burden of diabetes in pregnancy on society is growing. Although congenital anomaly rates have declined in women with diabetes, perinatal mortality rates remain unchanged, and the risk of both remains significantly elevated compared with nondiabetic women. Increased efforts are needed to reduce these adverse outcomes. © 2014 by the American Diabetes Association.

A carefully classified dataset of perinatal mortality will retain the most significant information on the causes of death. Such information is needed for health care policy development, surveillance and international comparisons, clinical services and research. For comparability purposes, we propose a classification system that could serve all these needs, and be applicable in both developing and developed countries. It is developed to adhere to basic concepts of underlying cause in the International Classification of Diseases (ICD), although gaps in ICD prevent classification of perinatal deaths solely on existing ICD codes. We tested the Causes of Death and Associated Conditions (Codac) classification for perinatal deaths in seven populations, including two developing country settings. We identified areas of potential improvements in the ability to retain existing information, ease of use and inter-rater agreement. After revisions to address these issues we propose Version II of Codac with detailed coding instructions. The ten main categories of Codac consist of three key contributors to global perinatal mortality (intrapartum events, infections and congenital anomalies), two crucial aspects of perinatal mortality (unknown causes of death and termination of pregnancy), a clear distinction of conditions relevant only to the neonatal period and the remaining conditions are arranged in the four anatomical compartments (fetal, cord, placental and maternal). For more detail there are 94 subcategories, further specified in 577 categories in the full version. Codac is designed to accommodate both the main cause of death as well as two associated conditions. We suggest reporting not only the main cause of death, but also the associated relevant conditions so that scenarios of combined conditions and events are captured. The appropriately applied Codac system promises to better manage information on causes of perinatal deaths, the conditions associated with them, and the most common clinical scenarios for future study and comparisons.

A carefully classified dataset of perinatal mortality will retain the most significant information on the causes of death. Such information is needed for health care policy development, surveillance and international comparisons, clinical services and research. For comparability purposes, we propose a classification system that could serve all these needs, and be applicable in both developing and developed countries. It is developed to adhere to basic concepts of underlying cause in the International Classification of Diseases (ICD), although gaps in ICD prevent classification of perinatal deaths solely on existing ICD codes.We tested the Causes of Death and Associated Conditions (Codac) classification for perinatal deaths in seven populations, including two developing country settings. We identified areas of potential improvements in the ability to retain existing information, ease of use and inter-rater agreement. After revisions to address these issues we propose Version II of Codac with detailed coding instructions.The ten main categories of Codac consist of three key contributors to global perinatal mortality (intrapartum events, infections and congenital anomalies), two crucial aspects of perinatal mortality (unknown causes of death and termination of pregnancy), a clear distinction of conditions relevant only to the neonatal period and the remaining conditions are arranged in the four anatomical compartments (fetal, cord, placental and maternal).For more detail there are 94 subcategories, further specified in 577 categories in the full version. Codac is designed to accommodate both the main cause of death as well as two associated conditions. We suggest reporting not only the main cause of death, but also the associated relevant conditions so that scenarios of combined conditions and events are captured.The appropriately applied Codac system promises to better manage information on causes of perinatal deaths, the conditions associated with them, and the most common clinical scenarios for future study and comparisons.

Small for gestational age (SGA) infants have been classically defined as having birth weight less than two standard deviations below the mean or less than the 10th percentile of a population-specific birth weight for specific gestational age, whereas intrauterine growth restriction (IUGR) has been defined as a rate of foetal growth that is less than normal for the population and for the growth potential of a specific infant. SGA infants have more frequent problems such as perinatal asphyxia, hypothermia, hypoglycaemia, polycythaemia and many more when compared with their appropriate for gestational age counterpart. They too have growth retardation and various major and subtle neurodevelopmental handicaps, with higher rates of perinatal and neonatal mortality. With the advent of newer technologies, even though the perinatal diagnosis of these SGA/IUGR foetuses has increased, but still perinatal morbidity and mortality rates are higher than normal foetuses and infants. In this part, we have covered neonatal IUGR classification, postnatal diagnosis, short-term and long-term complications faced by these IUGR infants.

Background The first European Perinatal Health Report showed wide variability between European countries in fetal (2.6–9.1‰) and neonatal (1.6–5.7‰) mortality rates in 2004. We investigated gestational age patterns of fetal and neonatal mortality to improve our understanding of the differences between countries with low and high mortality. Methodology/Principal Findings Data on 29 countries/regions participating in the Euro-Peristat project were analyzed. Most European countries had no limits for the registration of live births, but substantial variations in limits for registration of stillbirths before 28 weeks of gestation existed. Country rankings changed markedly after excluding deaths most likely to be affected by registration differences (22–23 weeks for neonatal mortality and 22–27 weeks for fetal mortality). Countries with high fetal mortality ≥28 weeks had on average higher proportions of fetal deaths at and near term (≥37 weeks), while proportions of fetal deaths at earlier gestational ages (28–31 and 32–36 weeks) were higher in low fetal mortality countries. Countries with high neonatal mortality rates ≥24 weeks, all new member states of the European Union, had high gestational age-specific neonatal mortality rates for all gestational-age subgroups; they also had high fetal mortality, as well as high early and late neonatal mortality. In contrast, other countries with similar levels of neonatal mortality had varying levels of fetal mortality, and among these countries early and late neonatal mortality were negatively correlated. Conclusions For valid European comparisons, all countries should register births and deaths from at least 22 weeks of gestation and should be able to distinguish late terminations of pregnancy from stillbirths. After excluding deaths most likely to be influenced by existing registration differences, important variations in both levels and patterns of fetal and neonatal mortality rates were found. These disparities raise questions for future research about the effectiveness of medical policies and care in European countries. PMID:22110575

Intrauterine growth restriction (IUGR) and prematurity have been associated with increased perinatal morbidity and mortality and also with cardiovascular foetal programming. However, there are few studies on the impact of placenta-related IUGR on perinatal outcomes and cardiovascular biomarkers in pre-term infants. To determine differences in neonatal morbidity, mortality and cord blood biomarkers of cardiovascular dysfunction between pre-term placenta-related IUGR and non-IUGR new-borns, and to analyse their relationship with the severity of IUGR according to foetal Doppler evaluation. Prospective cohort study: pre-term infants with placenta-related IUGR and matched pre-term infants without IUGR. A Doppler scan was performed, and placenta-IUGR was classified according to severity. Comparative analysis of perinatal outcomes, neonatal morbidity and mortality, and cord blood levels of biomarkers of cardiovascular dysfunction was performed. IUGR new-borns present lower weight, length, head circumference, and Apgar score at birth, as well as increased neonatal and cardiovascular dysfunction biomarker levels, compared with pre-term new-borns without IUGR. These differences increase with the severity of IUGR determined by prenatal umbilical artery Doppler scan. Placenta-related-IUGR pre-term infants, irrespective of gestational age, present increased neonatal morbidity and mortality that is significantly proportional to the severity of IUGR. Placental impairment and severity also determine levels of cardiovascular dysfunction biomarkers at birth. Copyright © 2015 Asociación Española de Pediatría. Publicado por Elsevier España, S.L.U.

Health transition in Brazil: regional variations and divergence/convergence in mortality.

PubMed

Borges, Gabriel Mendes

2017-08-21

This study analyzes the main characteristics of the health transition in Brazil and its five major regions, using a framework that accounts for regional inequalities in mortality trends. The regional mortality divergence/convergence process is described and discussed by considering the specific contributions of age groups and causes of death in life expectancy variations. Results show that mortality change in Brazil has follow the epidemiologic transition theory to some extent during the period under analysis - for instance, the sharp decline in infant mortality in all regions (first from infectious and parasitic diseases and then from causes associated with the perinatal period) and the increase in the participation of chronic and degenerative diseases as the main cause of death. However, some features of Brazilian transition have not followed the linear and unidirectional pattern proposed by the epidemiologic transition theory, which helps to understand the periods of regional divergence in life expectancy, despite the long-term trends showing reducing regional inequalities. The emergence of HIV/AIDS, the persistence of relatively high levels of other infections and parasitic diseases, the regional differences in the unexpected mortality improvements from cardiovascular diseases, and the rapid and strong variations in mortality from external causes are some of the examples.

Action plan to reduce perinatal mortality.

PubMed

Bhakoo, O N; Kumar, R

1990-01-01

The government of India has set a goal of reducing perinatal mortality from its current rate of 48/1000 to 30-35/1000 by the year 2000. Perinatal deaths result from maternal malnutrition, inadequate prenatal care, complications of delivery, and infections in the postpartum period. Since reductions in perinatal mortality require attention to social, economic, and behavioral factors, as well as improvements in the health care delivery system, a comprehensive strategy is required. Social measures, such as raising the age at marriage to 18 years for females, improving the nutritional status of adolescent girls, reducing the strenuousness of work during pregnancy, improving female literacy, raising women's status in the society and thus in the family, and poverty alleviation programs, would all help eliminate the extent of complications of pregnancy. Measures required to enhance infant survival include improved prenatal care, prenatal tetanus toxoid immunization, use of sterile disposable cord care kits, the provision of mucus extractors and resuscitation materials to birth attendants, the creation of neonatal care units in health facilities, and more efficient referral of high-risk newborns and mothers. Since 90% of births in rural India take place at home priority must be given to training traditional birth attendants in the identification of high risk factors during pregnancy, delivery, and the newborn period.

Antepartum transabdominal amnioinfusion.

To determine the usefulness of antepartum transabdominal amnioinfusion (APTA) in reducing perinatal morbidity and mortality due to oligohydramnios. In this case-control study of 100 pregnant women with oligohydramnios, 50 received APTA and 50 were treated conservatively. These controls were matched for age, parity, and pregnancy duration with the case patients. There was a mean 4.02-cm increase in amniotic fluid index (AFI) after amnioinfusion. Only 18% of case patients required cesarean sections vs. 46% of controls. The perinatal mortality rate was 18% among controls and 4% among case patients, and the difference was significant. Antepartum amnioinfusion is a useful procedure to reduce complications resulting from decreased intra-amniotic volume. It is especially useful in preterm pregnancies, where the procedure allows for a better perinatal outcome by prolonging the duration of pregnancy.

An overview of the literature on congenital lower urinary tract obstruction and introduction to the PLUTO trial: percutaneous shunting in lower urinary tract obstruction.

PubMed

Morris, R Katie; Kilby, Mark D

2009-02-01

Congenital lower urinary tract obstruction (LUTO) comprises a heterogeneous group of pathologies causing obstruction to the urethra, the most common being posterior urethral valves. Such pathology is often associated with high perinatal mortality and varying degrees of perinatal and infant morbidity. A high proportion of LUTO may be visualised during routine second trimester (and first trimester) ultrasound giving rise to the possibility of determining individual fetal prognosis and treatments such as vesico-amniotic shunting, with a view to altering pathogenesis. The aims of the percutaneous shunting in low urinary tract obstruction (PLUTO) trial are to determine the effectiveness of these treatments and accuracy of the investigations with the primary outcome measures being perinatal mortality and postnatal renal function.

Reducing stillbirths: interventions during labour

Background Approximately one million stillbirths occur annually during labour; most of these stillbirths occur in low and middle-income countries and are associated with absent, inadequate, or delayed obstetric care. The low proportion of intrapartum stillbirths in high-income countries suggests that intrapartum stillbirths are largely preventable with quality intrapartum care, including prompt recognition and management of intrapartum complications. The evidence for impact of intrapartum interventions on stillbirth and perinatal mortality outcomes has not yet been systematically examined. Methods We undertook a systematic review of the published literature, searching PubMed and the Cochrane Library, of trials and reviews (N = 230) that reported stillbirth or perinatal mortality outcomes for eight interventions delivered during labour. Where eligible randomised controlled trials had been published after the most recent Cochrane review on any given intervention, we incorporated these new trial findings into a new meta-analysis with the Cochrane included studies. Results We found a paucity of studies reporting statistically significant evidence of impact on perinatal mortality, especially on stillbirths. Available evidence suggests that operative delivery, especially Caesarean section, contributes to decreased stillbirth rates. Induction of labour rather than expectant management in post-term pregnancies showed strong evidence of impact, though there was not enough evidence to suggest superior safety for the fetus of any given drug or drugs for induction of labour. Planned Caesarean section for term breech presentation has been shown in a large randomised trial to reduce stillbirths, but the feasibility and consequences of implementing this intervention routinely in low-/middle-income countries add caveats to recommending its use. Magnesium sulphate for pre-eclampsia and eclampsia is effective in preventing eclamptic seizures, but studies have not demonstrated impact on perinatal mortality. There was limited evidence of impact for maternal hyperoxygenation, and concerns remain about maternal safety. Transcervical amnioinfusion for meconium staining appears promising for low/middle income-country application according to the findings of many small studies, but a large randomised trial of the intervention had no significant impact on perinatal mortality, suggesting that further studies are needed. Conclusion Although the global appeal to prioritise access to emergency obstetric care, especially vacuum extraction and Caesarean section, rests largely on observational and population-based data, these interventions are clearly life-saving in many cases of fetal compromise. Safe, comprehensive essential and emergency obstetric care is particularly needed, and can make the greatest impact on stillbirth rates, in low-resource settings. Other advanced interventions such as amnioinfusion and hyperoxygenation may reduce perinatal mortality, but concerns about safety and effectiveness require further study before they can be routinely included in programs.

Umbilical venous pulsation is an important sign of hemodynamic compromise, especially during fetal heart failure and asphyxia. The aim of this study was to determine of the blow flow in the middle cerebral artery and the umbilical artery in fetuses with umbilical venous pulsations. The investigation included 18 fetuses with signs of the intrauterine growth restriction and umbilical venous pulsations after 28th weeks of gestation. We evaluated cerebral-placental ratio (CPR) and pulsation index (PI) in the middle cerebral artery (MCA) and the umbilical artery (UA). We observed brain sparring effect in all cases of analyzing fetuses. There were 77,8% of abnormal flow pattern in umbilical artery. 13 fetuses had a single pulsation pattern in umbilical vein and another 5 had double pulsation pattern. The coexistence of umbilical vein pulsation and abnormal flow pattern in umbilical artery is closely related to increased perinatal mortality.

The perinatal period is a time of high risk for onset of depressive disorders and is associated with substantial morbidity and mortality, including maternal suicide. Perinatal depression comprises a heterogeneous group of clinical subtypes, and further refinement is needed to improve treatment outcomes. We sought to empirically identify and describe clinically relevant phenotypic subtypes of perinatal depression, and further characterise subtypes by time of symptom onset within pregnancy and three post-partum periods. Data were assembled from a subset of seven of 19 international sites in the Postpartum Depression: Action Towards Causes and Treatment (PACT) Consortium. In this analysis, the cohort was restricted to women aged 19-40 years with information about onset of depressive symptoms in the perinatal period and complete prospective data for the ten-item Edinburgh postnatal depression scale (EPDS). Principal components and common factor analysis were used to identify symptom dimensions in the EPDS. The National Institute of Mental Health research domain criteria functional constructs of negative valence and arousal were applied to the EPDS dimensions that reflect states of depressed mood, anhedonia, and anxiety. We used k-means clustering to identify subtypes of women sharing symptom patterns. Univariate and bivariate statistics were used to describe the subtypes. Data for 663 women were included in these analyses. We found evidence for three underlying dimensions measured by the EPDS: depressed mood, anxiety, and anhedonia. On the basis of these dimensions, we identified five distinct subtypes of perinatal depression: severe anxious depression, moderate anxious depression, anxious anhedonia, pure anhedonia, and resolved depression. These subtypes have clear differences in symptom quality and time of onset. Anxiety and anhedonia emerged as prominent symptom dimensions with post-partum onset and were notably severe. Our findings show that there might be different types and severity of perinatal depression with varying time of onset throughout pregnancy and post partum. These findings support the need for tailored treatments that improve outcomes for women with perinatal depression. Janssen Research & Development. Copyright © 2017 Elsevier Ltd. All rights reserved.

Background Breech deliveries have always been topical issues in obstetrics. Neonates undergoing term breech deliveries have long-term morbidity up to the school age irrespective of mode of delivery. Objective To determine prevalence and perinatal outcomes of singleton term breech delivery. Methods Hospital based cross-sectional study was conducted on 384 participants retrospectively. Descriptive and analytical statistics was used. Result A total of 384 breech deliveries were included. Prevalence of singleton breech deliveries in the hospital was 3.4%. The perinatal outcome of breech deliveries was 322 (83.9%). Adverse perinatal outcome of singleton term breech delivery was significantly associated with women's age of greater than or equal to 35 years (AOR = 2.62, 95% CI = 1.14–6.03), fully dilated cervix (AOR = 0.48, 95% CI = 0.25–0.91), ruptured membrane (AOR = 5.11, 95% CI = 2.25–11.6), and fetal weight of <2500 g (AOR = 6.77, 95% CI = 3.22–14.25). Conclusion Entrapment of head, birth asphyxia, and cord prolapse were the most common causes of perinatal mortality. Factors like fetal weight <2500 gm, mothers of age 35 years and above, those mothers not having a fully dilated cervix, and mothers with ruptured membrane were associated with increased perinatal mortality.

We investigated whether changes in perinatal outcomes occurred following introduction of key tobacco control policies in the Netherlands: smoke-free legislation in workplaces plus a tobacco tax increase and mass media campaign (January-February 2004); and extension of the smoke-free law to the hospitality industry, accompanied by another tax increase and mass media campaign (July 2008). This was a national quasi-experimental study using Netherlands Perinatal Registry data (2000-2011; registration: ClinicalTrials.gov NCT02189265). Primary outcome measures were: perinatal mortality, preterm birth, and being small-for-gestational age (SGA). The association with timing of the tobacco control policies was investigated using interrupted time series logistic regression analyses with adjustment for confounders. Among 2,069,695 singleton births, there were 13,027 (0.6%) perinatal deaths, 116,043 (5.6%) preterm live-births and 187,966 (9.1%) SGA live-births. The 2004 policies were not associated with significant changes in the odds of developing any of the primary outcomes. After the 2008 policy change, a -4.4% (95% CI -2.4; -6.4, p < 0.001) decrease in odds of being SGA was observed. A reduction in SGA births, but not preterm birth or perinatal mortality, was observed in the Netherlands after extension of the smoke-free workplace law to bars and restaurants in conjunction with a tax increase and mass media campaign.

Heat loss in the newborn after delivery could interfere with post-natal adaptation due to metabolic and hemodynamic instability. Associated perinatal factors and their relationship with morbidity and mortality during the neonatal period have not been systematically studied in our unit. To determine the temperature of very low birth weight (VLBW) infants on admission to our NICU, and to determine the associated perinatal variables, and the association of temperature with morbidity and mortality. Infants born in our maternity from January 2006 to November 2012, with birth weights (BW) 401 g to 1,499 g and/or less than 30 weeks gestational age, were included. A multivariate analysis was performed using the perinatal variables and the temperature on admission, as well as a logistic regression between these and the morbidity-mortality variables, in order to detect any independent associations. A total of 635 infants were included, with a mean (± SD) birth weight and gestational age of 1,137.6 ± 257.6g, and 29.5 ± 2.0 weeks, respectively. The mean admission temperature was 35.8 ± 0.6°C (range: 33.0-37.8°C). The proportion of infants with a temperature < 36°C was 44.4%. Independently associated perinatal variables were chorioamnionitis, birth weight, vaginal delivery, and advanced cardiopulmonary resuscitation (CPR). Admission hypothermia was associated with severe intraventricular haemorrhage (IVH) (grades 3 and 4) (OR: 0.377; 95% CI: 0.221-0.643; P<.001), and mortality (OR: 0.329; 95% CI: 0.208-0.519; P=.012). Hypothermia on admission is frequent among our VLBW infants. Birth weight, vaginal delivery, and advanced CPR were the principal variables associated with hypothermia. A low temperature on admission was related to an increased risk of IVH and mortality. Copyright © 2012 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.

Were multiple stressors a 'perfect storm' for northern Gulf of Mexico bottlenose dolphins (Tursiops truncatus) in 2011?

2012-01-01

An unusual number of near term and neonatal bottlenose dolphin (Tursiops truncatus) mortalities occurred in the northern Gulf of Mexico (nGOM) in 2011, during the first calving season after two well documented environmental perturbations; sustained cold weather in 2010 and the Deepwater Horizon oil spill (DWHOS). Preceding the stranding event, large volumes of cold freshwater entered the nGOM due to unusually large snowmelt on the adjacent watershed, providing a third potential stressor. We consider the possibility that this extreme cold and freshwater event contributed to the pattern of perinatal dolphin strandings along the nGOM coast. During the 4-month period starting January 2011, 186 bottlenose dolphins, including 46% perinatal calves (nearly double the percentage for the same time period from 2003-2010) washed ashore from Louisiana to western Florida. Comparison of the frequency distribution of strandings to flow rates and water temperature at a monitoring buoy outside Mobile Bay, Alabama (the 4(th) largest freshwater drainage in the U.S.) and along the nGOM coast showed that dolphin strandings peaked in Julian weeks 5, 8, and 12 (February and March), following water temperature minima by 2-3 weeks. If dolphin condition was already poor due to depleted food resources, bacterial infection, or other factors, it is plausible that the spring freshet contributed to the timing and location of the unique stranding event in early 2011. These data provide strong observational evidence to assess links between the timing of the DWHOS, other local environmental stressors, and mortality of a top local predator. Targeted analyses of tissues from stranded dolphins will be essential to define a cause of death, and our findings highlight the importance of considering environmental data along with biological samples to interpret stranding patterns during and after an unusual mortality event.

To examine the rates of obstetric intervention and associated perinatal mortality and morbidity in the first 28 days among low-risk women giving birth in private and public hospitals in NSW (2000-2008). Linked data population-based retrospective cohort study involving five data sets. New South Wales, Australia. 691 738 women giving birth to a singleton baby during the period 2000-2008. Rates of neonatal resuscitation, perinatal mortality, neonatal admission following birth and readmission to hospital in the first 28 days of life in public and private obstetric units. Rates of obstetric intervention among low-risk women were higher in private hospitals, with primiparous women 20% less likely to have a normal vaginal birth compared to the public sector. Neonates born in private hospitals were more likely to be less than 40 weeks; more likely to have some form of resuscitation; less likely to have an Apgar <7 at 5 min. Neonates born in private hospitals to low-risk mothers were more likely to have a morbidity attached to the birth admission and to be readmitted to hospital in the first 28 days for birth trauma (5% vs 3.6%); hypoxia (1.7% vs 1.2%); jaundice (4.8% vs 3%); feeding difficulties (4% vs 2.4%) ; sleep/behavioural issues (0.2% vs 0.1%); respiratory conditions (1.2% vs 0.8%) and circumcision (5.6 vs 0.3%) but they were less likely to be admitted for prophylactic antibiotics (0.2% vs 0.6%) and for socioeconomic circumstances (0.1% vs 0.7%). Rates of perinatal mortality were not statistically different between the two groups. For low-risk women, care in a private hospital, which includes higher rates of intervention, appears to be associated with higher rates of morbidity seen in the neonate and no evidence of a reduction in perinatal mortality.

In pregnancy, violence can have serious health consequences that could affect both mother and child. In Ghana there are limited data on this subject. We sought to assess the relationship between physical violence during pregnancy and pregnancy outcomes (early pregnancy loss, perinatal mortality and neonatal mortality) in Ghana. The 2008 Ghana Demographic and Health Survey data were used. For the domestic violence module, 2563 women were approached of whom 2442 women completed the module. After excluding missing values and applying the weight factor, 1745 women remained. Logistic regression analysis was performed to assess the relationship between physical violence in pregnancy and adverse pregnancy outcomes with adjustments for potential confounders. About five percent of the women experienced violence during their pregnancy. Physical violence in pregnancy was positively associated with perinatal mortality and neonatal mortality, but not with early pregnancy loss. The differences remained largely unchanged after adjustment for age, parity, education level, wealth status, marital status and place of residence: adjusted odds ratios were 2.32; 95% CI: 1.34-4.01 for perinatal mortality, 1.86; 95% CI: 1.05-3.30 for neonatal mortality and 1.16; 95% CI: 0.60-2.24 for early pregnancy loss. Our findings suggest that violence during pregnancy is related to adverse pregnancy outcomes in Ghana. Major efforts are needed to tackle violence during pregnancy. This can be achieved through measures that are directed towards the right target groups. Measures should include education, empowerment and improving socio-economic status of women.

Exposure to intimate partner violence (IPV) in the perinatal period is associated with obstetric complications, poor maternal mental health, neonatal complications, and increased risk of infant mortality and morbidity. Less is known about how IPV may influence small for gestational age (SGA) birth. Data were obtained for 231,081 United States mothers who delivered neonates from 2004 to 2011 and completed the Pregnancy Risk Assessment Monitoring System survey 2-9 months after delivery. Weighted descriptive statistics and multivariate logistic regression models were used. IPV in the year before or during pregnancy was related to SGA bivariately (odds ratio 1.39, 95% confidence interval [CI] 1.28, 1.51), and after adjustment for demographic and obstetric factors, this association attenuated after further adjustment for perinatal smoking patterns, (adjusted odds ratio [aOR] 1.06, 95% CI 0.97, 1.15). Compared with nonabused women, women experiencing perinatal IPV were more than twice as likely to smoke before pregnancy (aOR 2.34, 95% CI 2.19, 2.49), and nearly 1.5 times as likely to report sustained smoking into the last 3 months of pregnancy (aOR 1.45, 95% CI 1.32, 1.59). In turn, among prepregnancy smokers, sustained smoking was associated with delivery of a SGA neonate (aOR 1.87, 95% CI 1.72, 2.03), fully attenuating the association of perinatal IPV with SGA. Women who experienced perinatal IPV were significantly more likely to smoke prepregnancy and sustain smoking into the last 3 months of pregnancy. Through behavioral and physiological pathways, smoking cessation may be uniquely challenging for women experiencing IPV, yet critical to address clinically to mitigate risk for SGA.

The social disparity in perinatal mortality may vary by the age of the offspring. We studied offspring mortality from pregnancy week 16 until 1 year after birth by maternal educational level. We included all births in Norwegian women during the years 1999-2004 (n = 297 663). The Medical Birth Registry of Norway was linked to the Norwegian Education Registry to obtain individual information on maternal education at the time of delivery. Information on infant mortality was obtained by linkage to the Norwegian Central Person Registry. In pregnancy weeks 37 through 43 and in the first week after birth, there was little difference in offspring mortality by maternal education. Before pregnancy week 37, the excess offspring mortality associated with compulsory school only was >60% using university/college education as the reference. During the 2nd through 12th month after birth, the excess mortality was 132% in offspring of mothers with compulsory school only. The social disparity in offspring mortality was lowest in pregnancies at term and in the first week after birth. In this period, all women living in Norway and their infants use the public health care service extensively. Our results may suggest that health care that is equally available to all citizens, reduces social disparities in mortality.

Placental Abruption and Perinatal Mortality With Preterm Delivery as a Mediator: Disentangling Direct and Indirect Effects

Ananth, Cande V.; VanderWeele, Tyler J.

2011-01-01

The authors use recent methodology in causal inference to disentangle the direct and indirect effects that operate through a mediator in an exposure-response association paradigm. They demonstrate how total effects can be partitioned into direct and indirect effects even when the exposure and mediator interact. The impact of bias due to unmeasured confounding on the exposure-response association is assessed through a series of sensitivity analyses. These methods are applied to a problem in perinatal epidemiology to examine the extent to which the effect of abruption on perinatal mortality is mediated through preterm delivery. Data on over 26 million US singleton births (1995–2002) were utilized. Risks of mortality among abruption and nonabruption births were 102.7 and 6.2 per 1,000 births, respectively. Risk ratios of the natural direct and indirect (preterm delivery-mediated) effects of abruption on mortality were 10.18 (95% confidence interval: 9.80, 10.58) and 1.35 (95% confidence interval: 1.33, 1.38), respectively. The proportion of increased mortality risk mediated through preterm delivery was 28.1%, with even higher proportions associated with deliveries at earlier gestational ages. Sensitivity analyses underscore that the qualitative conclusions of some mediated effects and substantial direct effects are reasonably robust to unmeasured confounding of a fairly considerable magnitude.

Reasons for Persistently High Maternal and Perinatal Mortalities in Ethiopia: Part II-Socio-Economic and Cultural Factors

PubMed Central

Berhan, Yifru; Berhan, Asres

2014-01-01

Background The major causes of maternal and perinatal deaths are mostly pregnancy related. However, there are several predisposing factors for the increased risk of pregnancy related complications and deaths in developing countries. The objective of this review was to grossly estimate the effect of selected socioeconomic and cultural factors on maternal mortality, stillbirths and neonatal mortality in Ethiopia. Methods A comprehensive literature review was conducted focusing on the effect of total fertility rate (TFR), modern contraceptive use, harmful traditional practice, adult literacy rate and level of income on maternal and perinatal mortalities. For the majority of the data, regression analysis and Pearson correlation coefficient were used as a proxy indicator for the association of variables with maternal, fetal and neonatal mortality. Results Although there were variations in the methods for estimation, the TFR of women in Ethiopia declined from 5.9 to 4.8 in the last fifteen years, which was in the middle as compared with that of other African countries. The preference of injectable contraceptive method has increased by 7-fold, but the unmet contraceptive need was among the highest in Africa. About 50% reduction in female genital cutting (FGC) was reported although some women's attitude was positive towards the practice of FGC. The regression analysis demonstrated increased risk of stillbirths, neonatal and maternal mortality with increased TFR. The increased adult literacy rate was associated with increased antenatal care and skilled person attended delivery. Low adult literacy was also found to have a negative association with stillbirths and neonatal and maternal mortality. A similar trend was also observed with income. Conclusion Maternal mortality ratio, stillbirth rate and neonatal mortality rate had inverse relations with income and adult education. In Ethiopia, the high total fertility rate, low utilization of contraceptive methods, low adult literacy rate, low income and prevalent harmful traditional practices have probably contributed to the high maternal mortality ratio, stillbirth and neonatal mortality rates.

We aimed to determine the prevalence and risks of late fetal deaths (LFDs) and early neonatal deaths (ENDs) in women with medical and obstetric complications. Secondary analysis of the WHO Multicountry Survey on Maternal and Newborn Health (WHOMCS). A total of 359 participating facilities in 29 countries. A total of 308 392 singleton deliveries. We reported on perinatal indicators and determined risks of perinatal death in the presence of severe maternal complications (haemorrhagic, infectious, and hypertensive disorders, and other medical conditions). Fresh and macerated LFDs (defined as stillbirths ≥ 1000 g and/or ≥28 weeks of gestation) and ENDs. The LFD rate was 17.7 per 1000 births; 64.8% were fresh stillbirths. The END rate was 8.4 per 1000 liveborns; 67.1% occurred by day 3 of life. Maternal complications were present in 22.9, 27.7, and 21.2% [corrected] of macerated LFDs, fresh LFDs, and ENDs, respectively. The risks of all three perinatal mortality outcomes were significantly increased with placental abruption, ruptured uterus, systemic infections/sepsis, pre-eclampsia, eclampsia, and severe anaemia. Preventing intrapartum-related perinatal deaths requires a comprehensive approach to quality intrapartum care, beyond the provision of caesarean section. Early identification and management of women with complications could improve maternal and perinatal outcomes. © 2014 RCOG The World Health Organization retains copyright and all other rights in the manuscript of this article as submitted for publication.

While there are good data to describe changing trends in mortality and morbidity rates for preterm populations, there is very little information on the specific causes and pattern of death in terms of age of vulnerability. It is well established that mortality increases with decreasing gestational age but there are limited data on the specific causes that account for this increased mortality. The aim of this study was to establish the common causes of hospital mortality in a regional preterm population admitted to a neonatal intensive care unit (NICU). Retrospective analysis of prospectively collected data of the Neonatal Intensive Care Units' (NICUS) Data Collection of all 10 NICUs in the region. Infants <32 weeks gestation without major congenital anomalies admitted from 2007 to 2011 were included. Three authors reviewed all cases to agree upon the immediate cause of death. There were 345 (7.7%) deaths out of 4454 infants. The most common cause of death across all gestational groups was major IVH (cause-specific mortality rate [CMR] 22 per 1000 infants), followed by acute respiratory illnesses [ARI] (CMR 21 per 1000 infants) and sepsis (CMR 12 per 1000 infants). The most common cause of death was different in each gestational group (22-25 weeks [ARI], 26-28 weeks [IVH] and 29-31 weeks [perinatal asphyxia]). Pregnancy induced hypertension, antenatal steroids and chorioamnionitis were all associated with changes in CMRs. Deaths due to ARI or major IVH were more likely to occur at an earlier age (median [quartiles] 1.4 [0.3-4.4] and 3.6 [1.9-6.6] days respectively) in comparison to NEC and miscellaneous causes (25.2 [15.4-37.3] and 25.8 [3.2-68.9] days respectively). Major IVH and ARI were the most common causes of hospital mortality in this extreme to very preterm population. Perinatal factors have a significant impact on cause-specific mortality. The varying timing of death provides insight into the prolonged vulnerability for diseases such as necrotising enterocolitis in our preterm population.

Perinatal Depression – the Fourth Inflammatory Morbidity of Pregnancy? Theory and Literature Review

PubMed Central

Osborne, Lauren M.; Monk, Catherine

2015-01-01

Perinatal depression is one of the leading causes of maternal morbidity and mortality. The biological etiology of this disorder remains in question, despite considerable research into the contributions of hormonal imbalance, the role of monoamines, and dysregulation of the HPA axis. Because inflammation is known to be associated with major depression in men and non-perinatal women as well as with other important morbidities of pregnancy (such as preeclampsia, preterm birth, and gestational diabetes), and because these morbidities may correlate with perinatal depression, inflammation may be a common physiological pathway that can also help explain perinatal depression. In this paper, we review the theoretical background of inflammation in perinatal depression and then review the literature concerning immune and inflammatory factors in the etiology and course of perinatal depression. We close with recommendations for future studies in this still relatively unexplored area. Identification and understanding of a common pathophysiology between other pregnancy morbidities and perinatal depression would link physical and mental well-being, likely leading to better treatment and prevention.

To determine the intrapartum and perinatal results associated with different degrees of staining of meconium stained amniotic fluid (MSAF). In a retrospective cohort study of all singleton deliveries over a period of one year (2015) in a tertiary hospital, we compared different degrees of MSAF (yellow, green and thick) to clear amniotic fluids, and analysed in each group maternal, intrapartum and neonatal variables as well as umbilical cord blood gas analysis. Of the 3590 deliveries included, 503 (14%) had MSAF. The incidence of MSAF rises with gestational age at delivery, reaching 20.7% in gestations above 41 weeks compared to 4.3% below 37 weeks. As the amniotic fluid staining progresses we found a higher proportion of intrapartum fevers (p < 0.001), pathological fetal heart rate patterns (p < 0.05), operative vaginal deliveries and cesarean sections (p < 0.001), as well as the need for advanced neonatal resuscitation (p < 0.001). There was also a correlation between MSAF and low Apgar scores at five minutes (p < 0.001) and fetal-neonatal mortality (p < 0.001) but there was not a higher proportion of neonatal intensive care admissions (p > 0.05). We have observed a similar distribution of umbilical artery pH ranges in all groups (p > 0.05). MSAF was associated with an increase in the rate of pathological fetal heart rate patterns, intrapartum fevers, operative vaginal and cesarean section deliveries, need for neonatal resuscitation, low Apgar scores and higher fetal-neonatal mortality. Moreover, we found that the risks increase as the staining and consistency of the amniotic fluid evolves so it should alert the obstetrician and paediatrician to the potential adverse outcomes.

Study the association between the introduction of tobacco control policies in the Netherlands and changes in perinatal outcomes. National quasi-experimental study. We used Netherlands Perinatal Registry data (now called Perined) for the period 2000-2011. We studied whether the introduction of smoke-free legislation in workplaces plus a tobacco tax increase and mass media campaign in January 2004, and extension of the smoke-free law to the hospitality industry accompanied by another tax increase and media campaign in July 2008, was associated with changes in perinatal outcomes. We studied all singleton births (gestational age: 24+0 to 42+6 weeks). Our primary outcome measures were: perinatal mortality, preterm birth and being small-for-gestational-age (SGA). Interrupted time series logistic regression analyses were performed to investigate changes in these outcomes occurred after the introduction of the aforementioned tobacco control policies (ClinicalTrials.gov: NCT02189265). Among 2,069,695 singleton births, 13,027 (0.6%) perinatal deaths, 116,043 (5.6%) preterm live-births and 187,966 (9.1%) SGA live-births were observed. The policies introduced in January 2004 were not associated with significant changes in any of the primary outcome measures. A -4.4% (95% CI: -6.4 to -2.4; p < 0.001) decrease in odds of a SGA birth was observed after the policy extension in July 2008 to include a smoke-free hospitality industry, a further tax increase and another media campaign. This translates to an estimated over 500 cases of SGA being averted per year. A reduction in SGA births, but not preterm birth or perinatal mortality, was observed in the Netherlands after extension of the smoke-free workplace law to include bars and restaurants, in conjunction with a tax increase and media campaign in 2008.

To assess the proportion of severe maternal outcomes resulting from indirect causes, and to determine pregnancy outcomes of women with indirect causes. Secondary analysis of the WHO Multicountry Survey on Maternal and Newborn Health. A total of 359 health facilities in 29 countries in Africa, Asia, Latin America, and the Middle East. A total of 314 623 pregnant women admitted to the participating facilities. We identified the percentage of women with severe maternal outcomes arising from indirect causes. We evaluated the risk of severe maternal and perinatal outcomes in women with, versus without, underlying indirect causes, using adjusted odds ratios and 95% confidence intervals, by a multilevel, multivariate logistic regression model, accounting for clustering effects within countries and health facilities. Severe maternal outcomes and preterm birth, fetal mortality, early neonatal mortality, perinatal mortality, low birthweight, and neonatal intensive care unit admission. Amongst 314 623 included women, 2822 were reported to suffer from severe maternal outcomes, out of which 20.9% (589/2822; 95% CI 20.1-21.6%) were associated with indirect causes. The most common indirect cause was anaemia (50%). Women with underlying indirect causes showed significantly higher risk of obstetric complications (adjusted odds ratio, aOR, 7.0; 95% CI 6.6-7.4), severe maternal outcomes (aOR 27.9; 95% CI 24.7-31.6), and perinatal mortality (aOR 3.8; 95% CI 3.5-4.1). Indirect causes were responsible for about one-fifth of severe maternal outcomes. Women with underlying indirect causes had significantly increased risks of severe maternal and perinatal outcomes. © 2014 RCOG The World Health Organization retains copyright and all other rights in the manuscript of this article as submitted for publication.

 The objective of this study was to describe the relationship between early pregnancy body mass index (BMI) and maternal, perinatal, and neonatal outcomes in rural India and Pakistan.  In a prospective, population-based pregnancy registry implemented in communities in Thatta, Pakistan and Nagpur and Belagavi, India, we obtained women's BMI prior to 12 weeks' gestation (categorized as underweight, normal, overweight, and obese following World Health Organization criteria). Outcomes were assessed 42 days postpartum.  The proportion of women with an adverse maternal outcome increased with increasing maternal BMI. Less than one-third of nonoverweight/nonobese women, 47.2% of overweight women, and 56.0% of obese women experienced an adverse maternal outcome. After controlling for site, maternal age and parity, risks of hypertensive disease/severe preeclampsia/eclampsia, cesarean/assisted delivery, and antibiotic use were higher among women with higher BMIs. Overweight women also had significantly higher risk of perinatal and early neonatal mortality compared with underweight/normal BMI women. Overweight women had a significantly higher perinatal mortality rate.  High BMI in early pregnancy was associated with increased risk of adverse maternal, perinatal, and neonatal outcomes in rural India and Pakistan. These findings present an opportunity to inform efforts for women to optimize weight prior to conception to improve pregnancy outcomes.

Prevention of perinatal group B streptococcal infections: a review with an Indian perspective.

Narava, S; Rajaram, G; Ramadevi, A; Prakash, G V; Mackenzie, S

2014-01-01

Group B Streptococcus (GBS) is an important cause of maternal and neonatal morbidity and mortality in many parts of the world. Asymptomatic colonisation of the vagina and rectum with Group B streptococci is common in pregnancy. Maternal colonisation of GBS can vary depending on ethnicity and geographical distribution. Vertical transmission of this organism from mother to foetus may lead to neonatal GBS disease. Intra-partum use of antibiotics in these women has led to a decrease in the rate of early onset but not late onset GBS disease. Identification of women with GBS is the key factor in the prevention of perinatal GBS disease. There are different screening strategies available to identify women at risk of perinatal GBS disease. Clinicians continue to face the challenge of choosing between preventive strategies to reduce the impact of perinatal GBS disease. Controversy exists regarding the ideal preventive strategy. In India, the mortality and morbidity associated with the GBS disease remains largely a under-recognised problem. This comprehensive review summarises the salient features of GBS disease and discusses the epidemiology, risk factors, screening strategies, intra-partum antibiotic prophylaxis with an Indian perspective and how it compares with the Western nations.

Smoke-free legislation is associated with improved early-life outcomes; however its impact on perinatal survival is unclear. We linked individual-level data with death certificates for all registered singletons births in England (1995–2011). We used interrupted time series logistic regression analysis to study changes in key adverse perinatal events following the July 2007 national, comprehensive smoke-free legislation. We studied 52,163 stillbirths and 10,238,950 live-births. Smoke-free legislation was associated with an immediate 7.8% (95%CI 3.5–11.8; p < 0.001) reduction in stillbirth, a 3.9% (95%CI 2.6–5.1; p < 0.001) reduction in low birth weight, and a 7.6% (95%CI 3.4–11.7; p = 0.001) reduction in neonatal mortality. No significant impact on SIDS was observed. Using a counterfactual scenario, we estimated that in the first four years following smoke-free legislation, 991 stillbirths, 5,470 cases of low birth weight, and 430 neonatal deaths were prevented. In conclusion, smoke-free legislation in England was associated with clinically important reductions in severe adverse perinatal outcomes. PMID:26268789

Prenatal diagnostics ultrasound was established in Russia in 2000 as a routine method of screening for birth defects. The aims of the current study were twofold: to assess changes in birth defects prevalence at birth and perinatal mortality after ultrasound screening was implemented and to estimate prenatal detection rates for congenital malformations in the city of Monchegorsk (Murmansk County, North-West Russia). The Murmansk County Birth Registry and the Kola Birth Registry were the primary sources of information, and include 30 448 pregnancy outcomes in Monchegorsk for the period 1973-2011. Data from these registries were supplemented with information derived from hospital records about pregnancy terminations for 2000-2007. The total number of newborns with any kind of birth defects in Monchegorsk during 1973-2011 was 1099, of whom 816 were born in the 1973-2000 period. The prevalence of defects at birth increased from 34.2/1000 (95% CI = 31.9-36.5) to 42.8/1000 newborns (95% CI = 38.0-47.7) after prenatal ultrasound screening was formally implemented. We observed significant decreases (p < 0.05) in the birth prevalence of congenital malformations of the circulatory system, the musculoskeletal system (including deformations), and other (excluding multiple); those of the urinary system increased from 0.9/1000 to 17.1/1000 (p < 0.0001). The perinatal mortality among newborns with any kind of malformation decreased from 106.6 per 1000 newborns with birth defects (95% CI = 84.3-129.1) to 21.2 (95 % CI = 4.3-38.1). Mothers who had undergone at least one ultrasound examination during pregnancy (n = 9883) had a decreased risk of having a newborn die during the perinatal period [adjusted OR = 0.49 (95% CI = 0.27-0.89)]. The overall prenatal detection rate was 34.9% with the highest for malformations of the nervous system. Improved detection of severe malformations with subsequent pregnancy termination was likely the main contributor to the observed decrease in perinatal mortality in Murmansk County, Russia.

To describe neonatal complications related to shoulder dystocia. This systematic evidence review is based on PubMed search, Cochrane library and experts' recommendations. The risks of brachial plexus birth injury, clavicle and humeral fracture, perinatal asphyxia, hypoxic-ischemic encephalopathy and perinatal mortality are increased after shoulder dystocia. The medical team should be able to provide neonatal resuscitation in the delivery room in case of perinatal asphyxia following shoulder dystocia, according to national and international guidelines. The initial clinical examination should search for complications such as brachial plexus birth injury or clavicle fracture. The risk of perinatal complications is increased in newborn after shoulder dystocia. The medical team should be able to manage these complications. Copyright © 2015 Elsevier Masson SAS.

Social deprivation is considered a key factor in adverse perinatal outcomes. Rotterdam, the second largest city in The Netherlands, has large inequalities in perinatal health and a high number of deprived neighbourhoods. Social deprivation is measured here through a composite variable: 'Social Index' (SI). We studied the impact of the SI (2008-2009; 5 categories) in terms of perinatal mortality, congenital anomalies, preterm birth, small for gestational age (SGA) and low 5-minute Apgar score as registered in The Netherlands Perinatal Registry (Rotterdam 2000-2007, n = 56,443 singleton pregnancies). We applied ethnic dichotomisation as Western (European/North-American/Australian) vs. Non-Western (all others) ethnicity was expected to interact with the impact of SI. Tests for trend and multilevel regression analysis were applied. Gradually decreasing prevalence of adverse perinatal outcomes was observed in Western women from the lowest SI category (low social quality) to the highest SI category (high social quality). In Western women the low-high SI gradient for prevalence of spontaneous preterm birth (per 1000) changed from 57.2 to 34.1, for iatrogenic preterm birth from 35.2 to 19.0, for SGA from 119.6 to 59.4, for low Apgar score from 10.9 to 8.2, and for perinatal mortality from 14.9 to 7.6. These trends were statistically confirmed by Chi2-tests for trend (p < 0.001). For non-Western women such trends were absent. These strong effects for Western women were confirmed by significant odds ratios for almost all adverse perinatal outcomes estimated from multilevel regression analysis. We conclude social deprivation to play a different role among Western vs. non-Western women. Our results suggest that improvements in social quality may improve perinatal outcomes in Western women, but alternative approaches may be necessary for non-Western groups. Suggested explanations for non-Western 'migrant' groups include the presence of 'protective' effects through knowledge systems or intrinsic resilience. Implications concern both general and targeted policies. Copyright © 2013 Elsevier Ltd. All rights reserved.

Audit and feedback is an established strategy for improving maternal, neonatal and child health. The Perinatal Problem Identification Programme (PPIP), implemented in South African public hospitals in the late 1990s, measures perinatal mortality rates and identifies avoidable factors associated with each death. The aim of this study was to elucidate the processes involved in the implementation and sustainability of this programme. Clinicians' experiences of the implementation and maintenance of PPIP were explored qualitatively in two workshop sessions. An analytical framework comprising six stages of change, divided into three phases, was used: pre-implementation (create awareness, commit to implementation); implementation (prepare to implement, implement) and institutionalisation (integrate into routine practice, sustain new practices). Four essential factors emerged as important for the successful implementation and sustainability of an audit system throughout the different stages of change: 1) drivers (agents of change) and team work, 2) clinical outreach visits and supervisory activities, 3) institutional perinatal review and feedback meetings, and 4) communication and networking between health system levels, health care facilities and different role-players.During the pre-implementation phase high perinatal mortality rates highlighted the problem and indicated the need to implement an audit programme (stage 1). Commitment to implementing the programme was achieved by obtaining buy-in from management, administration and health care practitioners (stage 2).Preparations in the implementation phase included the procurement and installation of software and training in its use (stage 3). Implementation began with the collection of data, followed by feedback at perinatal review meetings (stage 4).The institutionalisation phase was reached when the results of the audit were integrated into routine practice (stage 5) and when data collection had been sustained for a longer period (stage 6). Insights into the factors necessary for the successful implementation and maintenance of an audit programme and the process of change involved may also be transferable to similar low- and middle-income public health settings where the reduction of the neonatal mortality rate is a key objective in reaching Millennium Development Goal 4. A tool for reflecting on the implementation and maintenance of an audit programme is also proposed.

Neonatal mortality (NM) refers to deaths occurring between birth and 27 days of life. This component of infant mortality has shown the least reduction over the past 50 years. The objective of this study was to analyze the course and characteristics of NM in Argentina. This was a descriptive, ecological study of NM in Argentina conducted between 2005 and 2014 to analyze its course, causes, and the relevance of prematurity and a low birth weight. Records of the Health Statistics and Information Department of the Ministry of Health of Argentina were used. The neonatal mortality rate reduced by 19.2% (2005: 8.9‰; 2014: 7.2‰); the early component (between birth and 6 days of life), by 20% (2005: 6.5‰; 2014: 5.2‰); and the late component (between 7 and 27 days of life), by 13% (2005: 2.3‰; 2014: 2‰). Disorders originating in the perinatal period and congenital malformations were the cause of more than 95% of neonatal deaths in this period. The relative significance of disorders originating in the perinatal period reduced, but that of congenital malformations increased. Preterm and low birth weight live births had the greatest risk of neonatal death. A younger gestational age and a lower birth weight resulted in a lower reduction of specific neonatal mortality rate. In the past 10 years, NM has reduced significantly. Disorders originating in the perinatal period and congenital malformations were the cause of almost all deaths in this age group. NM was associated with a low birth weight and prematurity. Sociedad Argentina de Pediatría

The perinatal mortality rate remains a public health problem, demanding epidemiological studies to describe its magnitude and time trends, identify risk factors, and define adequate interventions. There are still methodological controversies, resulting in heterogeneous studies and possible biases. In Brazil, there has been a growing scientific output on this theme, mainly in the South and Southeast of the country. Twenty-four articles from 1996 to 2003 were reviewed, focusing on definitions and classifications, data sources, study designs, measurement of variables, statistical analysis, and results. The review showed an increasing utilization of data bases (mainly SINASC and SIM), few studies on stillbirth, the incorporation of classification schemes, and disagreement concerning risk factors.

The purpose of this study was to evaluate the perinatal risk of death by chorionicity at >22 weeks of gestation of triplet pregnancies. In a retrospective cohort study, the perinatal data were collected from triplet pregnancies in Japanese perinatal care centers between 1999 and 2009. We included maternal characteristics and examined the following factors: prenatal interventions, pregnancy outcome, and neonatal outcome. The association between fetal or neonatal death of triplets and chorionicity was evaluated by logistic regression analysis. After the exclusion of 253 cases, the study group comprised 701 cases: 507 trichorionic triamniotic (TT) triplet pregnancies, 144 diamniotic triamniotic (DT) triplet pregnancies, and 50 monochorionic triamniotic (MT) triplet pregnancies. The mortality rate (fetal death at >22 weeks of gestation; neonatal death) in triplets was 2.6% and included 2.1% of TT triplet pregnancies, 3.2% of DT triplet pregnancies, and 5.3% of MT triplet pregnancies. No significant risk of death was identified in DT triplet pregnancies; however, MT triplet pregnancies had a 2.6-fold greater risk (adjusted odds ratio, 2.60; 95% confidence interval, 1.17-5.76; P = .019) compared with TT triplet pregnancies. Prophylactic cervical cerclage did not reduce the perinatal mortality rate at >22 weeks of gestation in triplets. The risk of death for MT triplet pregnancies is significantly higher than that of TT triplet pregnancies; however, the risk of death for DT triplet pregnancies is not. Copyright © 2013 Mosby, Inc.

To compare perinatal outcomes between spontaneous conception and assisted reproductive technologies (ART) among patients of advanced maternal age. The present retrospective study included data from singleton pregnancies of women aged at least 40 years who delivered between January 1, 1991, and December 31, 2013, at Soroka University Medical Center, Beer Sheva, Israel. Demographic, obstetric, and perinatal data were compared between pregnancies conceived with ART (in vitro fertilization [IVF] or ovulation induction) and those conceived spontaneously. Multiple regression models were used to define independent predictors of adverse outcomes. A total of 8244 singleton pregnancies were included; 229 (2.8%) following IVF, 86 (1.0%) following ovulation induction, and 7929 (96.2%) were spontaneous. Preterm delivery (P<0.001), fetal growth restriction (FGR) (P<0.001), and cesarean delivery (P<0.001) demonstrated linear associations with the conception mode; the highest rates for each were observed for IVF, with decreased rates for ovulation induction and spontaneous conception. The incidence of gestational diabetes and hypertensive disorders were highest among pregnancies following ART. No association was observed between conception mode and perinatal mortality. Multivariate logistic regression demonstrated that IVF was independently associated with increased odds of preterm delivery (P<0.001) and FGR (P=0.027) compared with spontaneous conception. Among patients of advanced maternal age, ART were independently associated with increased FGR and preterm delivery rates compared with spontaneous pregnancies; perinatal mortality was comparable. © 2017 International Federation of Gynecology and Obstetrics.

Perinatal networks have yielded substantial contribution in decreasing the neonatal mortality rate. We present here the process of implementation of a perinatal network in Yaoundé (Cameroon) based on the WhatsApp messenger application as well as some preliminary results and achievements. In December 2016, the Yaoundé Perinatal Network was launched, regrouping a multidisciplinary team of health professionals dealing with perinatal care in Yaoundé, Cameroon. The network takes advantage of WhatsApp facilities and is coordinated by 5 administrators. One of their main duties is to have a twice-daily updated status of the available equipment (incubators, oxygen and phototherapy) and bed capacities across the Yaoundé pediatric units. Once a request is sent through the network, other members react, either by giving advice or by telling where the desired equipment or expertise is available at that moment. Then, the baby is immediately prepared for transfer, occurring once the receiving pediatric unit has attested that it is already prepared to receive the new patient. From December 18, 2016 to July 31, 2017, 139 members representing all the principal maternities and tertiary pediatric units in Yaoundé were already included in the network. The network permitted instant sharing of knowledge and information between its members for an optimal delivery of care. Two hundred and seventeen neonates were transferred using the network; the median time of response after a request had been sent was 19.5 min and the delay in transferring a neonate averaged 70 min. Taking account of the preliminary promising notes, there is hope that the Yaoundé Perinatal Network will help to reduce neonatal mortality in our context. Lessons learned from its implementation will serve to replicate this innovative health action in other towns of the country. Moreover, this experience could be a source of inspiration for other countries facing similar challenges.

Perinatal asphyxia can cause neuronal loss and depletion of neurotransmitters within the striatum. The striatum plays an important role in motor control, sensorimotor integration and learning. In the present study we investigated whether perinatal asphyxia leads to motor deficits related to striatal damage, and in particular to the loss of GABAergic neurons. Perinatal asphyxia was induced in time-pregnant Wistar rats on the day of delivery by placing the uterus horns, containing the pups, in a 37 degrees C water bath for 20 min. Three motor performance tasks (open field, grip test and walking pattern) were performed at 3 and 6 weeks of age. Antibodies against calbindin and parvalbumin were used to stain GABAergic striatal projection neurons and interneurons, respectively. The motor tests revealed subtle effects of perinatal asphyxia, i.e. small decrease in motor activity. Analysis of the walking pattern revealed an increase in stride width at 6 weeks of age after perinatal asphyxia. Furthermore, a substantial loss of calbindin-immunoreactive (-22%) and parvalbumin-immunoreactive (-43%) cells was found in the striatum following perinatal asphyxia at two months of age. GABA(A) receptor autoradiography revealed no changes in GABA binding activity within the striatum, globus pallidus or substantia nigra. We conclude that perinatal asphyxia resulted in a loss of GABAergic projection neurons and interneurons in the striatum without alteration of GABA(A) receptor affinity. Despite a considerable loss of striatal neurons, only minor deficits in motor performance were found after perinatal asphyxia.

Fetal growth restriction (FGR) is a condition that affects 5-10% of pregnancies and is the second most common cause of perinatal mortality. This review presents the most recent knowledge on FGR and focuses on the etiology, classification, prediction, diagnosis, and management of the condition, as well as on its neurological complications. The Pubmed, SCOPUS, and Embase databases were searched using the term "fetal growth restriction". Fetal growth restriction (FGR) may be classified as early or late depending on the time of diagnosis. Early FGR (<32 weeks) is associated with substantial alterations in placental implantation with elevated hypoxia, which requires cardiovascular adaptation. Perinatal morbidity and mortality rates are high. Late FGR (≥32 weeks) presents with slight deficiencies in placentation, which leads to mild hypoxia and requires little cardiovascular adaptation. Perinatal morbidity and mortality rates are lower. The diagnosis of FGR may be clinical; however, an arterial and venous Doppler ultrasound examination is essential for diagnosis and follow-up. There are currently no treatments to control FGR; the time at which pregnancy is interrupted is of vital importance for protecting both the mother and fetus. Early diagnosis of FGR is very important, because it enables the identification of the etiology of the condition and adequate monitoring of the fetal status, thereby minimizing risks of premature birth and intrauterine hypoxia.

The organotin compound (OTC) triphenyltin (TPT) is used extensively as a herbicide, pesticide and fungicide in agriculture as well as, together with tributyltin (TBT), in marine antifouling paints. We studied the effects of in utero exposure to 2 or 6 mg triphenyltinchloride (TPTCl)/kgb.w. on pregnancy outcome and postnatal development in rat offspring. Gravid Wistar rats were treated per gavage from gestational day 6 until the end of lactation. In the 6 mg TPTCl dose group gestational mortality in dams as well as an increased incidence of anticipated and delayed parturition was observed. Furthermore, treatment resulted in a significant increase in perinatal mortality, a decrease in lactational body weight gain as well as in delayed physical maturation of offspring. Similarily, exposure to 2mg TPTCl/kgb.w. resulted in a significant increase in perinatal mortality and in delayed eye opening. Lactational body weight gain and other landmarks of physical maturation were unaffected in the low dose group. We conclude, that in utero exposure to TPTCl at the described dose levels severely affected pregnancy outcome and perinatal survival of offspring. These results were unexpected, as in two earlier studies with pubertal rats TPTCl at the same dose levels no signs of general toxicity were observed.

Maternal factors and perinatal outcome of low birth-weight (less than or equal to 2,500 g) infants of 46 adolescent mothers was studied and compared with 160 adolescents who delivered infants weighing greater than 2,500 g. The significant factors found in the low birth-weight group were anaemia, small maternal physique and preterm delivery. Expectedly, the perinatal mortality rate was significantly increased in low birth-weight infants.

Objective To determine the feasibility of introducing a simple indicator of quality of obstetric and neonatal care and to determine the proportion of potentially avoidable perinatal deaths in hospitals in low-income countries. Methods Between September 1, 2011, and February 29, 2012, data were collected from women who had a term pregnancy and were admitted to the labor ward of 1 of 6 hospitals in 4 low-income countries. Fetal heart tones on admission were monitored, and demographic and birth data were recorded. Results Data were obtained for 3555 women and 3593 neonates (including twins). The doptone was used on 97% of women admitted. The overall perinatal mortality rate was 34 deaths per 1000 deliveries. Of the perinatal deaths, 40%–45% occurred in the hospital and were potentially preventable by better hospital care. Conclusion The results demonstrated that it is possible to accurately determine fetal viability on admission via a doptone. Implementation of doptone use, coupled with a concise data record, might form the basis of a low-cost and sustainable program to monitor and evaluate efforts to improve quality of care and ultimately might to help to reduce the in-hospital component of perinatal mortality in low-income countries.

Dollars and sense. Efforts to reduce perinatal transmission fuel the debate over "haves" and "have nots".

HIV has become the single greatest contributor to child mortality in developing countries. Although clinical trials of azidovudine (AZT) in the US and Europe have revealed reductions of 43-66% in perinatal HIV transmission, the cost of this treatment regimen is prohibitive in developing countries. Of interest are recent findings that a short course of AZT (three oral doses daily beginning at 36 weeks' gestation and every 3 hours during labor) produces a 50% reduction in perinatal HIV transmission. The pharmaceutical firm Glaxo Wellcome has announced it will negotiate reduced AZT pricing with developing countries to increase treatment access. It is acknowledged, however, that discounted prices may still remain beyond the reach of countries in sub-Saharan Africa, for example. Even if discounted prices were complemented by other funding sources, the health infrastructure required to provide widespread counseling, testing, and treatment is not in place. Also problematic is the possibility that infants who are protected from perinatal HIV transmission will become infected postnatally as a result of lack of safe alternatives to breast-feeding. Moreover, unless treatment with triple-combination therapies and protease inhibitors is provided to HIV-infected women, their children will face increased mortality risks as a result of orphanhood.

Trends in perinatal deaths from 2010 to 2013 in the Guatemalan Western Highlands

PubMed Central

2015-01-01

Background While progress has been made in reducing neonatal mortality in Guatemala, stillbirth and maternal mortality rates remain high, especially among the indigenous populations, which have among the highest adverse pregnancy-related mortality rates in Guatemala. Methods We conducted a prospective study in the Western Highlands of Guatemala from 2010 through 2013, enrolling women during pregnancy with follow-up through 42-days postpartum. All pregnant women were identified and enrolled by study staff in the clusters in the Chimaltenango region for which we had 4 years of data. Enrolment usually occurred during the antenatal period; women were also visited following delivery and 42-days postpartum to collect outcomes. Measures of antenatal and delivery care were also obtained. Results Approximately four thousand women were enrolled annually (3,869 in 2010 to 4,570 in 2013). The stillbirth rate decreased significantly, from 22.0 per 1000 births (95% CI 16.6, 29.0) in 2010 to 16.7 (95% CI 13.5, 20.6) in 2013 (p-value 0.0223). The perinatal mortality rate decreased from 43.9 per 1,000 births (95% CI 36.0, 53.6) to 31.6 (95% CI 27.2, 36.7) (p-value 0.0003). The 28-day neonatal mortality rate decreased from 28.9 per 1000 live births (95% CI 25.2, 33.2) to 21.7 (95% CI 17.5, 26.9), p-value 0.0004. The maternal mortality rate was 134 per 100,000 in 2010 vs. 113 per 100,000 in 2013. Over the same period, hospital birth rates increased from 30.0 to 50.3%. Conclusions In a relatively short time period, significant improvements in neonatal, fetal and perinatal mortality were noted in an area of Guatemala with a history of poor pregnancy outcomes. These changes were temporally related to major increases in hospital-based delivery with skilled birth attendants, as well as improvements in the quality of delivery care, neonatal care, and prenatal care.

Evidence from community level inputs to improve quality of care for maternal and newborn health: interventions and findings

PubMed Central

2014-01-01

Annually around 40 million mothers give birth at home without any trained health worker. Consequently, most of the maternal and neonatal mortalities occur at the community level due to lack of good quality care during labour and birth. Interventions delivered at the community level have not only been advocated to improve access and coverage of essential interventions but also to reduce the existing disparities and reaching the hard to reach. In this paper, we have reviewed the effectiveness of care delivered through community level inputs for improving maternal and newborn health outcomes. We considered all available systematic reviews published before May 2013 on the pre-defined community level interventions and report findings from 43 systematic reviews. Findings suggest that home visitation significantly improved antenatal care, tetanus immunization coverage, referral and early initiation of breast feeding with reductions in antenatal hospital admission, cesarean-section rates birth, maternal morbidity, neonatal mortality and perinatal mortality. Task shifting to midwives and community health workers has shown to significantly improve immunization uptake and breast feeding initiation with reductions in antenatal hospitalization, episiotomy, instrumental delivery and hospital stay. Training of traditional birth attendants as a part of community based intervention package has significant impact on referrals, early breast feeding, maternal morbidity, neonatal mortality, and perinatal mortality. Formation of community based support groups decreased maternal morbidity, neonatal mortality, perinatal mortality with improved referrals and early breast feeding rates. At community level, home visitation, community mobilization and training of community health workers and traditional birth attendants have the maximum potential to improve a range of maternal and newborn health outcomes. There is lack of data to establish effectiveness of outreach services, mass media campaigns and community education as standalone interventions. Future efforts should be concerted on increasing the availability and training of the community based skilled health workers especially in resource limited settings where the highest burden exists with limited resources to mobilize.

Fetal and neonatal mortality rates in low-income countries are at least 10-fold greater than in high-income countries. These differences have been related to poor access to and poor quality of obstetric and neonatal care. This trial tested the hypothesis that teams of health care providers, administrators and local residents can address the problem of limited access to quality obstetric and neonatal care and lead to a reduction in perinatal mortality in intervention compared to control locations. In seven geographic areas in five low-income and one middle-income country, most with high perinatal mortality rates and substantial numbers of home deliveries, we performed a cluster randomized non-masked trial of a package of interventions that included community mobilization focusing on birth planning and hospital transport, community birth attendant training in problem recognition, and facility staff training in the management of obstetric and neonatal emergencies. The primary outcome was perinatal mortality at ≥28 weeks gestation or birth weight ≥1000 g. Despite extensive effort in all sites in each of the three intervention areas, no differences emerged in the primary or any secondary outcome between the intervention and control clusters. In both groups, the mean perinatal mortality was 40.1/1,000 births (P = 0.9996). Neither were there differences between the two groups in outcomes in the last six months of the project, in the year following intervention cessation, nor in the clusters that best implemented the intervention. This cluster randomized comprehensive, large-scale, multi-sector intervention did not result in detectable impact on the proposed outcomes. While this does not negate the importance of these interventions, we expect that achieving improvement in pregnancy outcomes in these settings will require substantially more obstetric and neonatal care infrastructure than was available at the sites during this trial, and without them provider training and community mobilization will not be sufficient. Our results highlight the critical importance of evaluating outcomes in randomized trials, as interventions that should be effective may not be. ClinicalTrials.gov NCT01073488.

Fatalities from perinatal asphyxia remain high in developing countries, and continually assessing its risk factors will help improve outcomes in these settings. We explored how some identified risk factors predict mortality in asphyxiated newborns, to assist clinicians in prioritizing interventions. This was a 4-year prospective study conducted at the Enugu State University Teaching Hospital, Enugu, Nigeria. All newborns who met the study criteria that were admitted to this facility in this period were enrolled and monitored. Data collected were analysed with SPSS Version 18. A total of 161 newborns with perinatal asphyxia were enrolled into the study with an in-hospital incidence rate of 12.81 per 1000 birth and a case fatality rate of 18%. Overall, the APGAR scores were severe in 10%, moderate in 22%, mild to normal in 68%, whereas the SARNAT stages were III in 24%, II in 52%, and I in 25%. In terms of mortality, 66.7%, 22.2%, and 11.1% mortalities were, respectively, observed with SARNAT scores III, II, and I (P = .003), whereas the findings with APGAR were 31.2% (severe), 25.0% (moderate), 25.0% (mild), and 18.8% (normal) (P = .030). Fatality outcome was more correlated with SARNAT (R = .280; P = .000) than APGAR (R = −.247; P = .0125). The SARNAT score significantly differentiated between the degrees of asphyxia in newborns based on gestational age at delivery (P = .010), place of delivery (P = .032), and mode of delivery (P = .042). Finally, it was noted that newborns that were female (P = .007), or born outside the hospital (P = .010), or with oxygen saturations <60% (P = .001), or with heart rate <120 (P = .000), and those with respiratory rate <30 (P = .003), all have significantly higher likelihood of deaths from asphyxia. Therefore, predictors of neonatal mortality from perinatal asphyxia in our centre include being female and being born outside the hospital, as well as low oxygen saturations, heart rates, and respiratory rates at presentation.

In Mali and Senegal, over 1% of women die giving birth in hospital. At some hospitals, over a third of infants are stillborn. Many deaths are due to substandard medical practices. Criterion-based clinical audits (CBCA) are increasingly used to measure and improve obstetrical care in resource-limited settings, but their measurement properties have not been formally evaluated. In 2011, we published a systematic review of obstetrical CBCA highlighting insufficient considerations of validity and reliability. The objective of this study is to develop an obstetrical CBCA adapted to the West African context and assess its reliability and validity. This work was conducted as a sub-study within a cluster randomized trial known as QUARITE. Criteria were selected based on extensive literature review and expert opinion. Early 2010, two auditors applied the CBCA to identical samples at 8 sites in Mali and Senegal (n = 185) to evaluate inter-rater reliability. In 2010-11, we conducted CBCA at 32 hospitals to assess construct validity (n = 633 patients). We correlated hospital characteristics (resource availability, facility perinatal and maternal mortality) with mean hospital CBCA scores. We used generalized estimating equations to assess whether patient CBCA scores were associated with perinatal mortality. Results demonstrate substantial (ICC = 0.67, 95% CI 0.54; 0.76) to elevated inter-rater reliability (ICC = 0.84, 95% CI 0.77; 0.89) in Senegal and Mali, respectively. Resource availability positively correlated with mean hospital CBCA scores and maternal and perinatal mortality were inversely correlated with hospital CBCA scores. Poor CBCA scores, adjusted for hospital and patient characteristics, were significantly associated with perinatal mortality (OR 1.84, 95% CI 1.01-3.34). Our CBCA has substantial inter-rater reliability and there is compelling evidence of its validity as the tool performs according to theory. Current Controlled Trials ISRCTN46950658.

Nigeria has one of the highest maternal mortality ratios in the world as well as high perinatal mortality. Unfortunately, the country does not have the resources to assess this critical indicator with the conventional health information system and measuring its progress toward the goal of ending preventable maternal deaths is almost impossible. Médecins Sans Frontières (MSF) conducted a cross-sectional study to assess maternal and perinatal mortality in Makoko Riverine and Badia East, two of the most vulnerable slums of Lagos. The study was a cross-sectional, community-based household survey. Nearly 4,000 households were surveyed. The sisterhood method was utilized to estimate maternal mortality and the preceding births technique was used to estimate newborn and child mortality. Questions regarding health seeking behavior were posed to female interviewees and self-reported data were collected. Data was collected from 3963 respondents for a total of 7018 sisters ever married. The maternal mortality ratio was calculated at 1,050/100,000 live births (95% CI: 894-1215), and the lifetime risk of maternal death at 1:18. The neonatal mortality rate was extracted from 1967 pregnancies reported and was estimated at 28.4/1,000; infant mortality at 43.8/1,000 and under-five mortality at 103/1,000. Living in Badia, giving birth at home and belonging to the Egun ethnic group were associated with higher perinatal mortality. Half of the last pregnancies were reportedly delivered in private health facilities. Proximity to home was the main influencing factor (32.4%) associated with delivery at the health facility. The maternal mortality ratio found in these urban slum populations within Lagos is extremely high, compared to the figure estimated for Lagos State of 545 per 100,000 live births. Urgent attention is required to address these neglected and vulnerable neighborhoods. Efforts should be invested in obtaining data from poor, marginalized, and hard-to-reach populations in order to identify pockets of marginalization needing additional resources and tailored approaches to guarantee equitable treatment and timely access to quality health services for vulnerable groups. This study demonstrates the importance of sub-regional, disaggregated data to identify and redress inequities that exist among poor, remote, vulnerable populations-as in the urban slums of Lagos.

Perinatal mood and anxiety disorders are among the most common mental health conditions encountered by women of reproductive age. When left untreated, perinatal mood and anxiety disorders can have profound adverse effects on women and their children, ranging from increased risk of poor adherence to medical care, exacerbation of medical conditions, loss of interpersonal and financial resources, smoking and substance use, suicide, and infanticide. Perinatal mood and anxiety disorders are associated with increased risks of maternal and infant mortality and morbidity and are recognized as a significant patient safety issue. In 2015, the Council on Patient Safety in Women's Health Care convened an interdisciplinary workgroup to develop an evidence-based patient safety bundle to address maternal mental health. The focus of this bundle is perinatal mood and anxiety disorders. The bundle is modeled after other bundles released by the Council on Patient Safety in Women's Health Care and provides broad direction for incorporating perinatal mood and anxiety disorder screening, intervention, referral, and follow-up into maternity care practice across health care settings. This commentary provides information to assist with bundle implementation.

To present how the adjustment of incompleteness and misclassification of causes of death in the vital registration (VR) system can contribute to more accurate estimates of the risk of mortality from leading causes of death in northeastern Brazil. After estimating the total numbers of deaths by age and sex in Brazil's Northeast region in 2002-2004 by correcting for undercount in the VR data, adjustment algorithms were applied to the reported cause-of-death structure. Average annual age-standardized mortality rates were computed by cause, with and without the corrections, and compared to death rates for Brazil's South region after adjustments for potential misdiagnosis. Death rates from ischemic heart disease, lower respiratory infections, chronic obstructive pulmonary disease, and perinatal conditions were more than 100% higher for both sexes than what was suggested by the routine VR data. Corrected cause-specific mortality rates were higher in the Northeast region versus the South region for the majority of causes of death, including several noncommunicable conditions. Failure to adjust VR data for undercount of cases reported and misdiagnoses will cause underestimation of mortality risks for the populations of the Northeast region, which are more vulnerable than those in other regions of the country. In order to more reliably understand the pattern of disease, all cause-specific mortality rates in poor populations should be adjusted.

Global migration is at an all-time high with implications for perinatal health. Migrant women, especially asylum seekers and refugees, represent a particularly vulnerable group. Understanding the impact on the perinatal health of women and offspring is an important prerequisite to improving care and outcomes. The aim of this systematic review was to summarise the current evidence base on perinatal health outcomes and care among women with asylum seeker or refugee status. Twelve electronic database, reference list and citation searches (1 January 2007-July 2017) were carried out between June and July 2017. Quantitative and qualitative systematic reviews, published in the English language, were included if they reported perinatal health outcomes or care and clearly stated that they included asylum seekers or refugees. Screening for eligibility, data extraction, quality appraisal and evidence synthesis were carried out in duplicate. The results were summarised narratively. Among 3415 records screened, 29 systematic reviews met the inclusion criteria. Only one exclusively focussed on asylum seekers; the remaining reviews grouped asylum seekers and refugees with wider migrant populations. Perinatal outcomes were predominantly worse among migrant women, particularly mental health, maternal mortality, preterm birth and congenital anomalies. Access and use of care was obstructed by structural, organisational, social, personal and cultural barriers. Migrant women's experiences of care included negative communication, discrimination, poor relationships with health professionals, cultural clashes and negative experiences of clinical intervention. Additional data for asylum seekers and refugees demonstrated complex obstetric issues, sexual assault, offspring mortality, unwanted pregnancy, poverty, social isolation and experiences of racism, prejudice and stereotyping within perinatal healthcare. This review identified adverse pregnancy outcomes among asylum seeker and refugee women, representing a double burden of inequality for one of the most globally vulnerable groups of women. Improvements in the provision of perinatal healthcare could reduce inequalities in adverse outcomes and improve women's experiences of care. Strategies to overcome barriers to accessing care require immediate attention. The systematic review evidence base is limited by combining heterogeneous migrant, asylum seeker and refugee populations, inconsistent use of definitions and limited data on some perinatal outcomes and risk factors. Future research needs to overcome these limitations to improve data quality and address inequalities. Systematic review registration number: PROSPERO CRD42017073315 .

Death by suicide during the perinatal period has been understudied in Canada. We examined the epidemiology of and health service use related to suicides during pregnancy and the first postpartum year. In this retrospective, population-based cohort study, we linked health administrative databases with coroner death records (1994-2008) for Ontario, Canada. We compared sociodemographic characteristics, clinical features and health service use in the 30 days and 1 year before death between women who died by suicide perinatally, women who died by suicide outside of the perinatal period and living perinatal women. The perinatal suicide rate was 2.58 per 100 000 live births, with suicide accounting for 51 (5.3%) of 966 perinatal deaths. Most suicides occurred during the final quarter of the first postpartum year, with highest rates in rural and remote regions. Perinatal women were more likely to die from hanging (33.3% [17/51]) or jumping or falling (19.6% [10/51]) than women who died by suicide non-perinatally ( p = 0.04). Only 39.2% (20/51) had mental health contact within the 30 days before death, similar to the rate among those who died by suicide non-perinatally (47.7% [762/1597]; odds ratio [OR] 0.71, 95% confidence interval [CI] 0.40-1.25). Compared with living perinatal women matched by pregnancy or postpartum status at date of suicide, perinatal women who died by suicide had similar likelihood of non-mental health primary care and obstetric care before the index date but had a lower likelihood of pediatric contact (64.5% [20/31] v. 88.4% [137/155] at 30 days; OR 0.24, 95% CI 0.10-0.58). The perinatal suicide rate for Ontario during the period 1994-2008 was comparable to international estimates and represents a substantial component of Canadian perinatal mortality. Given that deaths by suicide occur throughout the perinatal period, all health care providers must be collectively vigilant in assessing risk. © 2017 Canadian Medical Association or its licensors.

The perinatal mortality of immigrants in Japan is higher than that of Japanese women. However, details of the problems of immigrant perinatal women that contribute to worsening of their health are still unknown. This review describes the physical, psychological, social, and economic problems of immigrant women during the perinatal period in Japan. Medline, CINAHL, PsycINFO, and Igaku-Chuo Zasshi were searched and 36 relevant articles were reviewed. The related descriptions were collected and analyzed by using content analysis. The results showed that immigrant perinatal women in Japan experienced the following problems: language barriers, a problematic relationship with a partner, illegal residency, emotional distress, physical distress, adjustment difficulties, lack of utilization of services, social isolation, lack of support, lack of information, low economic status, unsatisfactory health care, and discrimination. These results indicated that multilingual services, strengthening of social and support networks, and political action are necessary to resolve their problems.

To evaluate the impact of birth attendant training using the World Health Organization Essential Newborn Care (ENC) course among traditional birth attendants, with a particular emphasis on the effect of acquisition of skills on perinatal outcomes. Population-based, prospective, interventional pre-post design study. 11 rural clusters in Chimaltenango, Guatemala. Health care providers. This study analyzed the effect of training and implementation of the ENC health care provider training course between September 2005 and December 2006. The primary outcome measure was the rate of death from all causes in the first seven days after birth in fetuses/infants ≥1500g. Secondary outcome measures were overall rate of stillbirth, rate of perinatal death, which included stillbirths plus neonatal deaths in the first seven days in fetuses/infants ≥1500g. Perinatal mortality decreased from 39.5/1000 pre-ENC to 26.4 post-ENC (RR 0.72; 95%CI 0.54-0.97). This reduction was attributable almost entirely to a decrease in the stillbirth rate of 21.4/1000 pre-Essential Newborn Care to 7.9/1000 post-ENC (RR 0.40; 95%CI 0.25-0.64). Seven-day neonatal mortality did not decrease (18.3/1000 to 18.6/1000; RR 1.05; 95%CI 0.70-1.57). Essential Newborn Care training reduced stillbirths in a population-based controlled study with deliveries conducted almost exclusively by traditional birth attendants. Scale-up of this intervention in other settings might help assess reproducibility and sustainability. © Published [2012].

Background: Previous research has suggested that obstetric outcomes are similar for deliveries by family physicians and obstetricians, but many of these studies were small, and none of them adjusted for unmeasured selection bias. We compared obstetric outcomes between these provider types using an econometric method designed to adjust for unobserved confounding. Methods: We performed a retrospective population-based cohort study of all Canadian (except Quebec) hospital births with delivery by family physicians and obstetricians at more than 20 weeks gestational age, with birth weight greater than 500 g, between Apr. 1, 2006, and Mar. 31, 2009. The primary outcomes were the relative risks of in-hospital perinatal death and a composite of maternal mortality and major morbidity assessed with multivariable logistic regression and instrumental variable–adjusted multivariable regression. Results: After exclusions, there were 3600 perinatal deaths and 14 394 cases of maternal morbidity among 799 823 infants and 793 053 mothers at 390 hospitals. For deliveries by family physicians v. obstetricians, the relative risk of perinatal mortality was 0.98 (95% confidence interval [CI] 0.85–1.14) and of maternal morbidity was 0.81 (95% CI 0.70–0.94) according to logistic regression. The respective relative risks were 0.97 (95% CI 0.58–1.64) and 1.13 (95% CI 0.65–1.95) according to instrumental variable methods. Interpretation: After adjusting for both observed and unobserved confounders, we found a similar risk of perinatal mortality and adverse maternal outcome for obstetric deliveries by family physicians and obstetricians. Whether there are differences between these groups for other outcomes remains to be seen. PMID:26303244

Advances in perinatal care have led to a significant reduction in morbidity and mortality among very-low-birth-weight (VLBW) infants. Much of this progress is related to the prevention and management of respiratory disease. To evaluate changes in perinatal care and its influence on respiratory morbidity and mortality among VLBW infants in Spain in 2 consecutive periods (2002-2006 and 2007-2011). This is a retrospective analysis of data prospectively collected of all VLBW infants included in the Spanish SEN1500 network. Patients with major congenital anomalies, those who died in the delivery room (DR) and infants <230 or >346 weeks of gestational age (GA) were excluded. During the study period, out of 27,205 eligible VLBW infants, 24,598 (90.4%) met inclusion criteria. The most striking and statistically significant results found in the second period were: (i) reduction in the proportion of "outborn" patients; (ii) an increase in prenatal steroid administration; (iii) enhanced non-invasive respiratory support in the DR and NICU; (iv) reduction in invasive mechanical ventilation, surfactant administration, and steroids for bronchopulmonary dysplasia (BPD). Moreover, survival to hospital discharge increased (83.5 vs. 84.7%; p = 0.015); however, survival without BPD increased only among the most immature (230 to 266 weeks' GA) from 26.6 to 31.6% (p < 0.001). Enhanced adherence to international recommendations in perinatal care and a significant reduction in mortality were found during the second period. Survival without BPD increased only among the most immature. Further investigation is needed to optimize the strategies to prevent and manage respiratory disease in this group of patients. © 2017 S.

Early neonatal death: A challenge worldwide.

PubMed

2017-06-01

Early neonatal death (ENND), defined as the death of a newborn between zero and seven days after birth, represents 73% of all postnatal deaths worldwide. Despite a 50% reduction in childhood mortality, reduction of ENND has significantly lagged behind other Millennium Developmental Goal achievements and is a growing contributor to overall mortality in children aged <5 years. The etiology of ENND is closely related to the level of a country's industrialization. Hence, prematurity and congenital anomalies are the leading causes in high-income countries. Furthermore, sudden unexpected early neonatal deaths (SUEND) and collapse have only recently been identified as relevant and often preventable causes of death. Concomitantly, perinatal-related events such as asphyxia and infections are extremely relevant in Africa, South East Asia, and Latin America and, together with prematurity, are the principal contributors to ENND. In high-income countries, according to current research evidence, survival may be improved by applying antenatal and perinatal therapies and immediate newborn resuscitation, as well as by centralizing at-risk deliveries to centers with appropriate expertise available around the clock. In addition, resources should be allocated to the close surveillance of newborn infants, especially during the first hours of life. Many of the conditions leading to ENND in low-income countries are preventable with relatively easy and cost-effective interventions such as contraception, vaccination of pregnant women, hygienic delivery at a hospital, training health care workers in resuscitation practices, simplified algorithms that allow for early detection of perinatal infections, and early initiation of breastfeeding and skin-to-skin care. The future is promising. As initiatives undertaken in previous decades have led to substantial reduction in childhood mortality, it is expected that new initiatives targeting the perinatal/neonatal periods are bound to reduce ENND and provide these babies with a better future.

The risk of perinatal morbidity and mortality in twins is 3-7 times higher than in singletons. In comparison to dichorionic twins, monochorionic twins are at increased risk for perinatal mortality and serious morbidity. In both type of twins growth discordance can occur. Discordant growth of dichorionic twins could be due to differences in placental mass or differences in placental parenchymal lesions, whereas birth weight discordancy in monochorionic twins is caused by placental vascular anastomoses. In this review the different types of complications (acardiac twins, acute and chronic twin-twin transfusion syndrome) due to different combinations of vascular anastomoses are discussed in relation to a computer model developed to gain more insight into the development of the twin-twin transfusion syndrome. The angioarchitecture of 395 monochorionic twin placentas was studied. Mortality was highest in the absence of an arterio-arterial anastomosis (42%) and lowest in the presence of an arterio-arterial anastomosis (15%). If mortality occurred, pregnancies with double mortality usually had an arterio-arterial anastomosis. If pregnancies were complicated by one death, a veno-venous anastomosis is more likely to be present. In conclusion, monochorionic twin pregnancies are a high risk pregnancy with a high chance of both mortality and morbidity; placental characteristics are a major contributor to adverse outcome in these pregnancies.

The causal involvement of bovine viral diarrhoea virus (BVDV) and border disease virus (BDV) infection in bovine and ovine abortion and perinatal mortality remain unclear. From 1992 until 1994, 213 bovine and 31 ovine foetuses as well as 36 calves and 25 lambs which had died perinatally were investigated. Tissue samples were tested for the presence of pestiviruses and serum or fluid from the body cavities were analysed for the presence of pestivirus antibodies. Detection of pestiviruses was performed by (i) cell culture isolation, (ii) antigen ELISA and (iii) immunohistochemical staining for viral antigen. For antibody-testing an indirect ELISA was used. In nine bovine foetuses and in two calves BVDV was isolated. Pestiviruses, most likely BDV were detected in one ovine foetus and three lambs. In 6% of the bovine and 11% of the ovine foetuses anti-pestivirus antibodies were detected. However, clinical features and history of bovine cases did not show a correlation with the diagnostic results, In contrast, the presence of central nervous system signs in neonatal lambs and the detection of BDV was correlated.

Mothers' birth weight and survival of their offspring: population based study.

To test the hypothesis that a baby's survival is related to the mother's birth weight. Population based dataset for two generations. Population registry in Norway. All birth records for women born in Norway since 1967 were linked to births during 1981-94, thereby forming 105104 mother-offspring units. Perinatal mortality specific for weight for offspring in groups of maternal birth weight (with 500 g categories in both). A mother's birth weight was strongly associated with the weight of her baby. Maternal birth weight was associated with perinatal survival of her baby only for mothers with birth weights under 2000 g. These mothers were more likely to lose a baby in the perinatal period (odds ratio 2.3, 95% confidence interval 1.4 to 3.7). Among mothers with a birth weight over 2000 g there was no overall association between mother's weight and infant survival. There was, however, a strong interaction between mother's birth weight, infant birth weight, and infant survival. Mortality among small babies was much higher for those whose mothers had been large at birth. For example, babies weighing 2500-2999 g had a threefold higher mortality if their mother's birth weight had been high (> or = 4000 g) than if the mother had been small (2500-2999 g). Mothers who weighed less than 2000 g at birth have a higher risk of losing their own babies. For mothers who weighed > or = 2000 g their birth weight provides a benchmark for judging the growth of their offspring. Babies who are small relative to their mother's birth weight are at increased risk of mortality.

Despite the high prevalence and known morbidity and mortality caused by cigarette smoking, 60% to 70% of substance abuse treatment programs lack smoking cessation counseling or fail to offer pharmacotherapy for smoking cessation, including those programs designed to meet the needs of drug-dependent pregnant patients. Previous studies of staff knowledge, attitudes, and practices (S-KAP) at general substance abuse/HIV treatment programs have suggested that staff may contribute to the deficiency in smoking cessation treatment in these settings. It is not known whether similar deficiencies exist at perinatal substance abuse treatment programs. This study compared cigarette S-KAP in perinatal substance abuse (n = 41) and general substance abuse/HIV treatment (Veterans Affairs [VA] medical center, hospital-, and community-based) workforce samples (n = 335). Significant differences were seen between the 2 groups on all measures, but perinatal staff compared favorably to general staff only on measures of barriers to smoking cessation services. Perinatal staff compared unfavorably on all other measures: knowledge, beliefs/attitudes, self-efficacy, and smoking cessation practices. Pair-wise comparisons of knowledge and beliefs/attitudes revealed a significant difference between perinatal and VA staff; of self-efficacy, between perinatal and staff at all other settings; and of smoking cessation practices, between perinatal and VA and community-based staff. These results-showing deficiencies of perinatal staff on most S-KAP measures-are concerning and suggest that identifying gaps in and improving S-KAP in perinatal substance abuse programs is urgently needed, for which the VA may provide an efficacious model.

Pregnancy in patients with kidney grafts is considered high-risk. Determine perinatal complications in women with kidney transplants treated by our hospital and compare them with complications reported in national and international literature. We studied perinatal complications in 18 patients with renal transplantation who delivered 19 newborns and were treated between 1 January 2009 and 31 December 2010. Results were compared with previous reports. Maternal age: 28.27 ± 4.70 years old, parity: 2, interval from transplant to conception: 7.52 ± 6.20 years, first prenatal visit 14.35 ± 6.74 weeks, prenatal care: 18.88 ± 9.18 weeks, 6 prenatal visits, gestational age at birth: 33.11 ± 8.72 weeks. Maternal complications: cesarean section: 88.88%, blood transfusion: 38.88%, anaemia: 33.33%, premature rupture of membranes: 22.22%, preterm delivery: 22.22%, urinary tract infection: 16.66%, preeclampsia: 11.11%, uncontrolled hypertension: 11.11%, miscarriage: 11.11%, uterine antony: 5.55%, gestational diabetes: 0%, and mortality: 0%. Foetal complications: premature birth: 52.63%, mortality: 21.05%, intensive care: 21.05%, and low birth weight due to growth restriction: 10.52%. Transplantation complications: filtration impairment without need for dialysis: 5.55%, graft rejection: 0%, and graft loss: 0%. The frequency of perinatal complications was high. Pregnancy had no adverse effect on renal function and patient survival. Stable renal grafts in women of childbearing age is not necessarily a contraindication for pregnancy.

The study consisted of a retrospective analysis of 17 pregnant women presenting with oligohydramnios who were treated with amnioinfusion during pregnancy in a period from 2003 to 2006. The mean gestational age at first treatment was 24 weeks. The mean pre-procedure deepest pool of amniotic fluid was 1.8 cm and post-procedure was 3.8 cm. The mean number of infusions was 1.05. The mean first infusion to delivery interval was 31 days. Perinatal mortality was 88% and neonatal mortality was 35%, with only one baby surviving the neonatal period. There were three cases of chorioamnionitis, with one of these cases presenting with premature rupture of the membranes at the time of amnioinfusion. Transabdominal amnioinfusion is a useful procedure to reduce complications that result from oligohydramnios. Although the results show a high perinatal mortality, it must be borne in mind that most of these pregnancies had multiple fetal abnormalities with an already predicted poor outcome. Importantly, as this procedure increases the latency period, it may be useful in preterm pregnancies where prolonging the duration of the pregnancy may result in better perinatal outcome by improving important factors that influence survival including increased birthweight.

Neonatology is a relatively new sub-specialty so we aimed to review survival data in the context of advances in neonatal care. Review of neonatal survival for very low birthweight babies over the last 50 years. In the data collected from a single tertiary neonatal unit, survival for babies 501-1000 g improved from below 10% in 1959 to over 60% in 2009. Similarly, survival for babies 1001 to 1500 g has improved from approximately 50% to over 90%. During the study period, death due to extreme prematurity or cardiorespiratory problems, namely respiratory distress syndrome, fell from 90% in 1964 to only 45% of neonatal deaths in 2008. In addition to reporting the remarkable improvement in neonatal survival over this period, we have highlighted items of historical context. © 2012 The Authors.

Perinatal mood and anxiety disorders are among the most common mental health conditions encountered by women of reproductive age. When left untreated, perinatal mood and anxiety disorders can have profound adverse effects on women and their children, ranging from increased risk of poor adherence to medical care, exacerbation of medical conditions, loss of interpersonal and financial resources, smoking and substance use, suicide, and infanticide. Perinatal mood and anxiety disorders are associated with increased risks of maternal and infant mortality and morbidity and are recognized as a significant patient safety issue. In 2015, the Council on Patient Safety in Women's Health Care convened an interdisciplinary work group to develop an evidence-based patient safety bundle to address maternal mental health. The focus of this bundle is perinatal mood and anxiety disorders. The bundle is modeled after other bundles released by the Council on Patient Safety in Women's Health Care and provides broad direction for incorporating perinatal mood and anxiety disorder screening, intervention, referral, and follow-up into maternity care practice across health care settings. This commentary provides information to assist with bundle implementation. © 2017 by the American College of Nurse-Midwives.

Preeclampsia in Ecuador is an understudied subject since available epidemiological data are scarce. The aim of this study was to describe perinatal outcomes among singleton pregnancies complicated with preeclampsia and eclampsia in a sample of low-income Ecuadorian women. Pregnant women complicated with preeclampsia (mild and severe) and eclampsia (defined according to criteria of the ACOG) delivering at the Enrique C. Sotomayor Obstetrics and Gynecology Hospital, Guayaquil, Ecuador were surveyed with a structured questionnaire containing maternal (socio-demographic) and neonatal data. Perinatal outcomes were compared according to severity of clinical presentation. A total of 163 women with preeclampsia [mild (23.9%), severe (68.7%) and eclampsia (7.4%)] were surveyed. Perinatal mortality and stillbirth rate was similar among studied groups (mild vs. severe preeclampsia/eclampsia cases). However, severe cases displayed higher rates of adverse perinatal outcomes: lower birth Apgar scores, more preterm births, and more low birth weight and small for gestational age infants. Caesarean-section rate and the number of admissions to intensive or intermediate neonatal care were higher in severe cases. A similar trend was found when analysis excluded preterm gestations. In conclusion, in this specific low-income Ecuadorian population perinatal outcome was adverse in pregnancies complicated with severe preeclampsia/eclampsia.

Registered deaths from the vital statistics registration system of Lagos City, a system that was judged to be 60% complete, were analysed for the year 1977. Nearly 40% of total registered deaths were from infections, parasitic diseases and motor vehicle accidents. Of the reported deaths, 17.3% were from ill-defined conditions. Deaths from neoplasms, diseases of the nervous and sense organs, diseases of the digestive and genitourinary systems as well as those from congenital anomalies are relatively less frequent. Maternal mortality appears to be very high. The age pattern of mortality is different from that in the developed countries, a high proportion of the deaths in Lagos City being those of children aged under 5 years. Infant mortality is dominated by perinatal causes which constituted a huge 38.4% of deaths of infants under 1 year, the other important causes being dysentery and diarrhoea, pneumonia and tetanus. Among adults, death from motor vehicles accidents is the most important cause accounting for more than 26% of deaths in the age group 15 years and above. Other important causes of adult deaths are cerebrovascular disease, hypertensive disease, heart disease, pneumonia, dysentery and diarrhoea and complications of pregnancy. Well organized health services stressing antenatal care, preventive and health education services are needed to effect a reduction in mortality and bring about a general improvement in the health of the people.

Nigeria presently has the second highest absolute number of maternal deaths and perinatal deaths (stillbirth and neonatal deaths) in the world. The country accounts for up to 14% of global maternal deaths and is second only to India in the number of women who die during childbirth. Although all parts of the country are worsened by these staggering statistics, several lines of evidence show that most maternal, and perinatal deaths occur in the north-east and north-west geo-political zones where women have limited access to evidence-based maternal and neonatal health services. The proposed project intends to identify the demand and supply factors that prevent women from using PHCs for maternal and early new-born care in Nigeria, and to test innovative and community relevant interventions for improving women's access to PHC services, and thus, ultimately, to prevent maternal and perinatal deaths. An open-labelled, randomized controlled trial will is carried out in two local government areas selected based on three criteria (i) maternal mortality rates (ii) PHC utilization rates and (iii) and geographic localization. The study will be conducted over 54-months in six communities, with PHCs in six communities of similar status serving as control sites. Surveys about quality of care and maternal health services utilization will be carried out at baseline, at midterm and at end of the project to test the effectiveness of the intervention, alongside conventional epidemiological measures of maternal and perinatal mortality. Ethical approval for the study has been granted (reference no. NHREC/01/01/2007). The findings will be published in compliance with reporting guidelines for randomized controlled trials. The current Federal Government in Nigeria has identified PHC as its main strategy for increasing access to health in Nigeria. However, despite numerous efforts, there are persisting concerns that there is currently no scientific evidence on which to base the improvement of PHCs. The results of this study will identify barriers in the use of PHCs and will provide scientific evidence for effective and innovative interventions for improving PHCs that can be rolled out throughout the country.

Perinatal mortality in non-western migrants in Norway as compared to their countries of birth and to Norwegian women

PubMed Central

2013-01-01

Background A large number of women from countries with a high perinatal mortality rate (PMR) settle in countries with a low PMR. We compared the PMRs for migrants in Norway with the PMRs in their countries of birth. We also assessed the risk of perinatal death in offspring of migrant women as compared to offspring of Norwegian women. Methods The Medical Birth Registry of Norway and the Norwegian Central Person Registry provided data on births in Norway during the years 1986 to 2005 among all women born in Norway, Pakistan, Vietnam, Somalia, Sri Lanka, Philippines, Iraq, Thailand and Afghanistan. Information on the PMRs in the countries of birth was obtained from the World Health Organisation (WHO) for the years 1995, 2000 and 2004. Mean PMRs in Norway during 1986–2005 were calculated by mother’s country of birth, and the risks of perinatal death by country of birth were estimated as odds ratios (OR) using Norwegian women as the reference. Adjustments were made for mother’s age, plurality, parity, year of birth and gestational age at birth. Results The PMRs for migrants in Norway were lower than in their countries of birth. The largest difference was in Afghan women (97 deaths per 1000 births in Afghanistan versus 24 deaths per 1000 births in Afghan women in Norway), followed by Iraqi and Somali women. As compared with Norwegian women, the adjusted odds ratio (OR) of perinatal death was highest for Afghan (OR 4.01 CI: 2.40 – 6.71), Somali (OR 1.83 CI: 1.44 - 2.34) and Sri Lankan (OR 1.76 CI: 1.36 – 2.27) women. Conclusions The lower PMRs for migrants in Norway as compared to the PMRs in their countries of birth may be explained by access to better health care after migration. The increased risk of perinatal death in migrants as compared to Norwegians encourages further research. PMID:23320559

Effective maternal and perinatal audits are associated with improved quality of care and reduction of severe adverse outcome. Although audits at the level of care were formally introduced in Tanzania around 25 years ago, little information is available about their existence, performance, and practical barriers to their implementation. This study assessed the structure, process and impacts of maternal and perinatal death audit systems in clinical practice and presents a detailed account on how they could be improved. A cross sectional descriptive study was conducted in eight major hospitals in Dar es Salaam in January 2009. An in-depth interview guide was used for 29 health managers and members of the audit committees to investigate the existence, structure, process and outcome of such audits in clinical practice. A semi-structured questionnaire was used to interview 30 health care providers in the maternity wards to assess their awareness, attitude and practice towards audit systems. The 2007 institutional pregnancy outcome records were reviewed. Overall hospital based maternal mortality ratio was 218/100,000 live births (range: 0 - 385) and perinatal mortality rate was 44/1000 births (range: 17 - 147). Maternal and perinatal audit systems existed only in 4 and 3 hospitals respectively, and key decision makers did not take part in audit committees. Sixty percent of care providers were not aware of even a single action which had ever been implemented in their hospitals because of audit recommendations. There were neither records of the key decision points, action plan, nor regular analysis of the audit reports in any of the facilities where such audit systems existed. Maternal and perinatal audit systems in these institutions are poorly established in structure and process; and are less effective to improve the quality of care. Fundamental changes are urgently needed for successful audit systems in these institutions.

The impact of transmural multiprofessional simulation-based obstetric team training on perinatal outcome and quality of care in the Netherlands

PubMed Central

2014-01-01

Background Perinatal mortality and morbidity in the Netherlands is relatively high compared to other European countries. Our country has a unique system with an independent primary care providing care to low-risk pregnancies and a secondary/tertiary care responsible for high-risk pregnancies. About 65% of pregnant women in the Netherlands will be referred from primary to secondary care implicating multiple medical handovers. Dutch audits concluded that in the entire obstetric collaborative network process parameters could be improved. Studies have shown that obstetric team training improves perinatal outcome and that simulation-based obstetric team training implementing crew resource management (CRM) improves team performance. In addition, deliberate practice (DP) improves medical skills. The aim of this study is to analyse whether transmural multiprofessional simulation-based obstetric team training improves perinatal outcome. Methods/Design The study will be implemented in the south-eastern part of the Netherlands with an annual delivery rate of over 9,000. In this area secondary care is provided by four hospitals. Each hospital with referring primary care practices will form a cluster (study group). Within each cluster, teams will be formed of different care providers representing the obstetric collaborative network. CRM and elements of DP will be implemented in the training. To analyse the quality of care as perceived by patients, the Pregnancy and Childbirth Questionnaire (PCQ) will be used. Furthermore, self-reported collaboration between care providers will be assessed. Team performance will be measured by the Clinical Teamwork Scale (CTS). We employ a stepped-wedge trial design with a sequential roll-out of the trainings for the different study groups. Primary outcome will be perinatal mortality and/or admission to a NICU. Secondary outcome will be team performance, quality of care as perceived by patients, and collaboration among care providers. Conclusion The effect of transmural multiprofessional simulation-based obstetric team training on perinatal outcome has never been studied. We hypothesise that this training will improve perinatal outcome, team performance, and quality of care as perceived by patients and care providers.

Objective Trauma influences on perinatal maternal-child interactions may affect the organization of offspring physiological systems involved in health outcomes. This study used a novel advanced system recently adapted for infants to examine associations of maternal lifetime trauma and related psychological symptoms in the perinatal period with infant cardiorespiratory reactivity and behavioral distress in response to a laboratory stressor. Methods Mothers self-reported lifetime exposure to trauma, perinatal traumatic stress, and current symptoms of posttraumatic stress disorder (PTSD) and depression. Heart rate and indices of respiratory volume, timing, and thoraco-abdominal coordination were continuously recorded using a non-invasive respiratory inductance plethysmography device from 23 infants during the Still-Face Paradigm, a videotaped mother-infant dyadic assessment that included baseline, stressor, and recovery phases. Infant behavioral distress during the procedure was also assessed. Results Infants of mothers with low exposure to trauma and perinatal traumatic stress showed expected increases in behavioral distress and cardiorespiratory activation from baseline to stressor and decreases in these parameters from stressor to recovery. Infants of mothers exposed to multiple traumas and with elevated perinatal traumatic stress showed similar patterns of activation from baseline to stressor but failed to show decreases during recovery. These patterns were maintained after controlling for current maternal PTSD and depressive symptoms. Conclusions Maternal lifetime trauma exposure and traumatic stress during the perinatal period were associated with disrupted infant cardiorespiratory regulation and behavioral distress during a stressor protocol. These results support the concept of perinatal programming and its potential role in physical and mental health outcomes. PMID:19553287

Vitamin C transporter Slc23a1 links renal reabsorption, vitamin C tissue accumulation, and perinatal survival in mice

Levels of the necessary nutrient vitamin C (ascorbate) are tightly regulated by intestinal absorption, tissue accumulation, and renal reabsorption and excretion. Ascorbate levels are controlled in part by regulation of transport through at least 2 sodium-dependent transporters: Slc23a1 and Slc23a2 (also known as Svct1 and Svct2, respectively). Previous work indicates that Slc23a2 is essential for viability in mice, but the roles of Slc23a1 for viability and in adult physiology have not been determined. To investigate the contributions of Slc23a1 to plasma and tissue ascorbate concentrations in vivo, we generated Slc23a1–/– mice. Compared with wild-type mice, Slc23a1–/– mice increased ascorbate fractional excretion up to 18-fold. Hepatic portal ascorbate accumulation was nearly abolished, whereas intestinal absorption was marginally affected. Both heterozygous and knockout pups born to Slc23a1–/– dams exhibited approximately 45% perinatal mortality, and this was associated with lower plasma ascorbate concentrations in dams and pups. Perinatal mortality of Slc23a1–/– pups born to Slc23a1–/– dams was prevented by ascorbate supplementation during pregnancy. Taken together, these data indicate that ascorbate provided by the dam influenced perinatal survival. Although Slc23a1–/– mice lost as much as 70% of their ascorbate body stores in urine daily, we observed an unanticipated compensatory increase in ascorbate synthesis. These findings indicate a key role for Slc23a1 in renal ascorbate absorption and perinatal survival and reveal regulation of vitamin C biosynthesis in mice. PMID:20200446

To determine the prevalence of monochorionic monoamniotic (MCMA) twin pregnancies and to describe perinatal outcomes and clinical management of these pregnancies. This multicentre cohort study used population-based data on MCMA twin pregnancies from 11 Northern Survey of Twin and Multiple Pregnancy (NorSTAMP) maternity units for the prevalence estimation of MCMA twinning. Pregnancy outcomes at <24 weeks' gestation, antenatal parameters and perinatal outcomes (from ≥24 weeks to the first 28 days of life) were analysed using combined data on pregnancies with confirmed MCMA chorionicity from the NorSTAMP and the Southwest Thames Region of London Obstetric Research Collaborative (STORK) multiple pregnancy cohort for 2000-2013. The estimated total prevalence of MCMA twin pregnancies in the North of England was 8.2 per 1000 total twin pregnancies (59/7170), the birth prevalence was 0.08 per 1000 all (singleton and multiple) pregnancies. The rate of a spontaneous or iatrogenic fetal death at <24 weeks' gestation was 31.8% (54/170); the overall perinatal mortality was 14.7% (17/116), ranging from 69.2% at <30 weeks to 4.5% at ≥33 weeks' gestation. MCMA twins who survived in utero beyond 24 weeks were delivered, usually by caesarean section, at a median of 33 weeks of gestation (interquartile range=32-34). In MCMA twins surviving beyond 24 weeks of gestation, there was a higher survival rate compared to previous decades presumably due to early diagnosis, close surveillance and elective birth around 32-34 weeks of gestation. High perinatal mortality at early gestations was mainly attributed to extreme prematurity due to preterm spontaneous labour. This article is protected by copyright. All rights reserved.

Pulmonary hypoplasia is the most frequent congenital anomaly associated with perinatal mortality. A retrospective and descriptive review was conducted on cases of patients diagnosed with pulmonary hypoplasia between 1995 and 2014 in a tertiary university hospital. An analysis was made of the prenatal imaging, clinical manifestations, post-natal diagnostic tests, treatment and management, long-term follow up, and survival data. A total of 60 cases were identified, all of them with prenatal imaging. Sixteen patients required foetal surgery. Congenital diaphragmatic hernia was the most frequent diagnosis. Main clinical presentation was respiratory distress with severe hypoxemia and high requirements of mechanical ventilation. Mortality rate was 47% within first 60 days of life, and 75% for the first day of life. Pneumonia and recurrent bronchitis episodes were observed during follow-up. They had a lung function obstructive pattern, and their quality of life and exercise tolerance was good. High neonatal mortality and significant long-term morbidity associated with pulmonary hypoplasia requires an early diagnosis and a specialised multidisciplinary team management.

Perinatal stroke is a common cause of established neurological sequelae. Although several risk factors have been identified, many questions regarding causes and clinical outcomes remain unanswered. This study investigated the clinical manifestations and outcomes of perinatal stroke and identified its etiologies in Taiwan. We searched the reports of head magnetic resonance imaging and computed tomography performed between January 2003 and December 2012. The medical records of enrolled infants with perinatal stroke were also reviewed. Thirty infants with perinatal stroke were identified; 10 infants had perinatal arterial ischemic stroke (PAIS) and 20 had perinatal hemorrhagic stroke (PHS). Neonatal seizure was the most common manifestation and presented in 40% of infants with PAIS and 50% of infants with PHS. All survivors with PAIS and 77% of the surviving infants with PHS developed neurological sequelae. Acute seizure manifestation was associated with poststroke epilepsy in infants with PHS but not in infants with PAIS (86% vs. 0%, p=0.005). PAIS was mostly caused by dysfunctional hemostasis (20%) and embolism (20%), whereas PHS was mostly attributable to birth asphyxia (30%). Perinatal stroke is associated with high mortality and morbidity rates in infants. Clinically, it can be difficult to distinguish PAIS and PHS. One should keep a high level of suspicion, especially for PHS, if infants develop unexplained seizure, cyanosis, conscious change, anemia, and/or thrombocytopenia. A systematic diagnostic approach is helpful in identifying the etiologies of perinatal stroke. Copyright © 2016. Published by Elsevier B.V.

Post-traumatic stress disorder in the perinatal period: A concept analysis.

To report an analysis of the concept of perinatal post-traumatic stress disorder. Prevalence of perinatal post-traumatic stress disorder is rising in the USA, with 9% of the U.S. perinatal population diagnosed with the disorder and an additional 18% being at risk for the condition. Left untreated, adverse maternal-child outcomes result in increased morbidity, mortality and healthcare costs. Concept analysis via Walker and Avant's approach. The databases Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline, Academic Search Premier and PsychINFO were searched for articles, written in English, published between 2006-2015, containing the terms perinatal and post-traumatic stress disorder. Perinatal post-traumatic stress disorder owns unique attributes, antecedents and outcomes when compared to post-traumatic stress disorder in other contexts, and may be defined as a disorder arising after a traumatic experience, diagnosed any time from conception to 6 months postpartum, lasting longer than 1 month, leading to specific negative maternal symptoms and poor maternal-infant outcomes. Attributes include a diagnostic time frame (conception to 6 months postpartum), harmful prior or current trauma and specific diagnostic symptomatology defined in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition. Antecedents were identified as trauma (perinatal complications and abuse), postpartum depression and previous psychiatric history. Consequences comprised adverse maternal-infant outcomes. Further research on perinatal post-traumatic stress disorder antecedents, attributes and outcomes in ethnically diverse populations may provide clinicians a more comprehensive framework for identifying and treating perinatal post-traumatic stress disorder. Nurses are encouraged to increase their awareness of perinatal post-traumatic stress disorder for early assessment and intervention, and prevention of adverse maternal-infant outcomes. © 2017 John Wiley & Sons Ltd.

Where does distance matter? Distance to the closest maternity unit and risk of foetal and neonatal mortality in France.

The number of maternity units has declined in France, raising concerns about the possible impact of increasing travel distances on perinatal health outcomes. We investigated impact of distance to closest maternity unit on perinatal mortality. Data from the French National Vital Statistics Registry were used to construct foetal and neonatal mortality rates over 2001-08 by distance from mother's municipality of residence and the closest municipality with a maternity unit. Data from French neonatal mortality certificates were used to compute neonatal death rates after out-of-hospital birth. Relative risks by distance were estimated, adjusting for individual and municipal-level characteristics. Seven percent of births occurred to women residing at ≥30 km from a maternity unit and 1% at ≥45 km. Foetal and neonatal mortality rates were highest for women living at <5 km from a maternity unit. For foetal mortality, rates increased at ≥45 km compared with 5-45 km. In adjusted models, long distance to a maternity unit had no impact on overall mortality but women living closer to a maternity unit had a higher risk of neonatal mortality. Neonatal deaths associated with out-of-hospital birth were rare but more frequent at longer distances. At the municipal-level, higher percentages of unemployment and foreign-born residents were associated with increased mortality. Overall mortality was not associated with living far from a maternity unit. Mortality was elevated in municipalities with social risk factors and located closest to a maternity unit, reflecting the location of maternity units in deprived areas with risk factors for poor outcome. © The Author 2014.

It is unclear whether the high rates of low birth weight in South Asia are due to poor fetal growth or short pregnancy duration. Also, it is not known whether the traditional focus on preventing low birth weight has been successful. We addressed these and related issues by studying births in Kaniyambadi, South India, with births from Nova Scotia, Canada serving as a reference. Population-based data for 1986 to 2005 were obtained from the birth database of the Community Health and Development program in Kaniyambadi and from the Nova Scotia Atlee Perinatal Database. Menstrual dates were used to obtain comparable information on gestational age. Small-for-gestational age (SGA) live births were identified using both a recent Canadian and an older Indian fetal growth standard. The low birth weight and preterm birth rates were 17.0% versus 5.5% and 12.3% versus 6.9% in Kaniyambadi and Nova Scotia, respectively. SGA rates were 46.9% in Kaniyambadi and 7.5% in Nova Scotia when the Canadian fetal growth standard was used to define SGA and 6.7% in Kaniyambadi and < 1% in Nova Scotia when the Indian standard was used. In Kaniyambadi, low birth weight, preterm birth and perinatal mortality rates did not decrease between 1990 and 2005. SGA rates in Kaniyambadi declined significantly when SGA was based on the Indian standard but not when it was based on the Canadian standard. Maternal mortality rates fell by 85% (95% confidence interval 57% to 95%) in Kaniyambadi between 1986-90 and 2001-05. Perinatal mortality rates were 11.7 and 2.6 per 1,000 total births and cesarean delivery rates were 6.0% and 20.9% among live births >or= 2,500 g in Kaniyambadi and Nova Scotia, respectively. High rates of fetal growth restriction and relatively high rates of preterm birth are responsible for the high rates of low birth weight in South Asia. Increased emphasis is required on health services that address the morbidity and mortality in all birth weight categories.

Outcomes of Induction of Labour in Women with Previous Caesarean Delivery: A Retrospective Cohort Study Using a Population Database

Stock, Sarah J.; Ferguson, Evelyn; Duffy, Andrew; Ford, Ian; Chalmers, James; Norman, Jane E.

2013-01-01

Background There is evidence that induction of labour (IOL) around term reduces perinatal mortality and caesarean delivery rates when compared to expectant management of pregnancy (allowing the pregnancy to continue to await spontaneous labour or definitive indication for delivery). However, it is not clear whether IOL in women with a previous caesarean section confers the same benefits. The aim of this study was to describe outcomes of IOL at 39–41 weeks in women with one previous caesarean delivery and to compare outcomes of IOL or planned caesarean delivery to those of expectant management. Methods and Findings We performed a population-based retrospective cohort study of singleton births greater than 39 weeks gestation, in women with one previous caesarean delivery, in Scotland, UK 1981–2007 (n = 46,176). Outcomes included mode of delivery, perinatal mortality, neonatal unit admission, postpartum hemorrhage and uterine rupture. 40.1% (2,969/7,401) of women who underwent IOL 39–41 weeks were ultimately delivered by caesarean. When compared to expectant management IOL was associated with lower odds of caesarean delivery (adjusted odds ratio [AOR] after IOL at 39 weeks of 0.81 [95% CI 0.71–0.91]). There was no significant effect on the odds of perinatal mortality but greater odds of neonatal unit admission (AOR after IOL at 39 weeks of 1.29 [95% CI 1.08–1.55]). In contrast, when compared with expectant management, elective repeat caesarean delivery was associated with lower perinatal mortality (AOR after planned caesarean at 39 weeks of 0.23 [95% CI 0.07–0.75]) and, depending on gestation, the same or lower neonatal unit admission (AOR after planned caesarean at 39 weeks of 0.98 [0.90–1.07] at 40 weeks of 1.08 [0.94–1.23] and at 41 weeks of 0.77 [0.60–1.00]). Conclusions A more liberal policy of IOL in women with previous caesarean delivery may reduce repeat caesarean delivery, but increases the risks of neonatal complications. PMID:23565242

This research determined the rates of perinatal mortality among infants delivered under Ghana's national health insurance scheme (NHIS) compared to infants delivered under the previous "Cash and Carry" system in Northern Region, especially as the country takes stock of its progress toward meeting the Millennium Development Goals (MDG) 4 and 5. The labor and maternity wards delivery records of infants delivered before and after the implementation of the NHIS in Northern Region were examined. Records of available daily deliveries during the two health systems were extracted. Fisher's exact tests of non-random association were used to examine the bivariate association between categorical independent variables and perinatal mortality. On average, 8% of infants delivered during the health user-fee (Cash & Carry) died compared to about 4% infant deaths during the NHIS delivery fee exemption period in Northern Region, Ghana. There were no remarkable difference in the rate of infant deaths among mothers in almost all age categories in both the Cash and Carry and the NHIS periods except in mothers age 35 years and older. Infants born to multiparous mothers were significantly more likely to die than those born to first time mothers. There were more twin deaths during the Cash and Carry system (p = 0.001) compared to the NHIS system. Deliveries by caesarean section increased from an average of 14% in the "Cash and Carry" era to an average of 20% in the NHIS era. The overall rate of perinatal mortality declined by half (50%) in infants born during the NHIS era compared to the Cash and Carry era. However, caesarean deliveries increased during the NHIS era. These findings suggest that pregnant women in the Northern Region of Ghana were able to access the opportunity to utilize the NHIS for antenatal visits and possibly utilized skilled care at delivery at no cost or very minimal cost to them, which therefore improved Ghana's progress towards meeting the MDG 4, (reducing under-five deaths by two-thirds).

Considering the highest rate of morbidity and mortality in diamniotic monochorionic twins, the authors evaluated and compared the adverse obstetric and perinatal outcome in twin pregnancies according to chorionicity. A retrospective study was conducted in all twin deliveries that occurred in the Obstetric Unit of Maternidade Bissaya-Barreto, for a period of tree years (from the 1st of January 1999 until the 31st of December 2001). From de 140 diamniotic twin pregnancies studied, we considered two groups according to the chorionicity: monochorionic and dichorionic. We compared multiple parameters as, epidemiologic data, adverse obstetric outcome, gestacional delivery age, type of delivery and the morbidity, the mortality and the follow-up of the newborn. The statistic tests used were the X2 and the t student. From the 140 twin pregnancies included in the study, 66% (92 cases) presented dichorionic placentation and 34% (48 cases) were monochorionic. In the group of monochorionic pregnancies, we observed highly difference related to pathology of amniotic fluid (14.5% vs 2.2%), discordant fetal growth (41.6% vs 22.8%) and rate of preterm delivery (66.6% vs 32.6%). Related to the newborn we verified that they had a lower average birth weight (1988g vs 2295g), a highly rate of weight discordancy (23% vs 15.3%), intraventricular haemorrhage (2.2% vs 0%) and IUGR (6.6% vs 1.6%), statistically significant in the monochorionic group. Also the perinatal mortality rate was significantly higher in the monochorionic pregnancies (93.7 per thousand vs 21.7 per thousand). The high rate of morbidity and mortality related to the monochorionic twin pregnancies, implies the need of a correct identification of the type of chorionicity and also a high standard of prenatal surveillance in prenatal specialised health centers.

The aim of study was to compare some perinatal outcomes in mothers with type 1 diabetes mellitus (T1DM). All patients with T1DM delivered at the 1st Department of Obstetrics and Gynaecology of Faculty of Medicine, Comenius University in Bratislava from January 1st 2009 to December 31th 2015 were included to the study. Out of 118 diabetic mothers, 46.6 % had vasculopathy and 53. 4 % were without microvascular complications. In the vasculopathy group, significantly higher incidence rates of preeclampsia (49. 1 versus 19.1 %; p = 0.002) and caesarean section (89.1 versus 68.3 %; p = 0.017) were found. Neonatal morbidity and mortality rates were higher in vasculopathy group (but not statistically significantly). Preparation for pregnancy improves perinatal and neonatal results. Nevertheless, this preparation in our study group was received only in 9.3 %. Perinatal mortality was 25.4 per 1,000 total births. For pregnancy of diabetic women to become possible a qualified management must be provided. Good outcomes for both women and newborns are real when preparation for pregnancy and metabolic control before and during whole pregnancy are at adequate level (Tab. 3, Ref. 28).

This population-based study was aimed to determine whether there is an association between urinary tract infections (UTI) during pregnancy, among patients in whom antibiotic treatment was recommended, and maternal and perinatal outcome. A retrospective population-based study comparing all singleton pregnancies of patients with and without UTI was performed. Multiple logistic regression models were performed to control for confounders. Out of 199,093 deliveries, 2.3% (n = 4742) had UTI during pregnancy and delivery. Patients with UTI had significantly higher rates of intra-uterine growth restriction (IUGR), pre-eclampsia, caesarean deliveries (CD) and pre-term deliveries (either before 34 weeks or 37 weeks of gestation). Although controlling for possible confounders such as maternal age and parity, using multivariable analyses, the significant association between UTI and IUGR, pre-eclampsia, CD and preterm deliveries persisted. In contrast, no significant differences in 5-min Apgar scores less than 7 or perinatal mortality were noted between the groups (0.6% vs. 0.6%; p = 0.782, and 1.5% vs. 1.4%; p = 0.704, respectively). Maternal UTI is independently associated with pre-term delivery, pre-eclampsia, IUGR and CD. Nevertheless, it is not associated with increased rates of perinatal mortality compared with women without UTI.

To determine the perinatal risk factors for pneumothorax in Very-Low-Birth-Weight (VLBW) infants and the associated morbidity and mortality in this population. Retrospective analysis of data collected prospectively from a cohort of VLBW neonates assisted in our Unit (2006-2013). We included all consecutive in-born patients with ≤ 1500 g, without severe congenital anomalies. Perinatal history, demographics, interventions and clinical outcomes were collected. Associations were evaluated by logistic regression analysis. During the study period, 803 VLBW infants were assisted in our Unit, of whom 763 were inborn. Ten patients (1.2%) died in delivery room, and 18 (2.2%) with major congenital anomalies were excluded. Finally, 735 (91.5%) neonates were included in the study. Seventeen (2.3%) developed pneumothorax during the first week of life [median (IQR): 2 (1-2) days]. After correcting for GA and other confounders, prolonged rupture of membranes [aOR =1.002 (95% CI 1.000-1.003); p = 0.040] and surfactant administration [aOR = 6.281 (95% CI 1.688-23.373); p = 0.006] were the independent risk factors associated with pneumothorax. Patients with pneumothorax had lower probabilities of survival without major brain damage (MBD): aOR = 0.283 (95% CI = 0.095-0.879); p = 0.029. Pneumothorax in VLBW seems to be related to perinatal inflammation and surfactant administration, and it is significantly associated with a reduction in the probabilities of survival without MBD.

To investigate adverse reproductive outcomes among male employees in the Royal Norwegian Navy exposed to radiofrequency electromagnetic fields aboard fast patrol boats. Cohort study of Royal Norwegian Navy servicemen linked to the Medical Birth Registry of Norway, including singleton offspring born between 1967 and 2008 (n = 37,920). Exposure during the last 3 months before conception (acute) and exposure more than 3 months before conception (nonacute) were analyzed. Perinatal mortality and preeclampsia increased after service aboard fast patrol boats during an acute period and also after increased estimated radiofrequency exposure during an acute period, compared with service aboard other vessels. No associations were found between nonacute exposure and any of the reproductive outcomes. Paternal work aboard fast patrol boats during an acute period was associated with perinatal mortality and preeclampsia, but the cause is not clear.

Between 1954 and 1973, 101 heroin-addicted mothers gave birth to 149 babies at Vancouver General Hospital. Thirty-seven percent of the infants had low birth weights and two thirds were born preterm. Average birth weight was 2,710 gm as compared with an overall average of 3,420 gm for this hospital. Tobacco and alcohol abuse, and poor maternal nutrition probably contributed to the growth retardation. Withdrawal symptoms were observed in 68% of the babies, and this may have been aggravated by multiple drug use, which was prevalent, including alcohol, barbiturates, and "soft drugs." Neonatal mortality rate of 6.7% and a stillbirth rate of 4% resulted in a perinatal mortality rate of 10.7%. Prematurity, respiratory distress syndrome, and other perinatal complications related to an unfavorable social background accounted for most neonatal deaths, but none was attributable directly to narcotic withdrawal.

Summary Objective To document the impact of severe obstetric complications on post-partum health in mothers and mortality in babies over 12 months in Benin and to assess whether severe complications associated with perinatal death are particularly likely to lead to adverse health consequences. Methods Cohort study which followed women and their babies after a severe complication or an uncomplicated childbirth. Women were selected in hospitals and interviewed at home at discharge, and at 6 and 12 months post-partum. Women were invited for a medical check-up at 6 months and 12 months. Results The cohort includes 205 women with severe complications and a live birth, 64 women with severe complications and perinatal death and 440 women with uncomplicated delivery. Women with severe complications and a live birth were not dissimilar to women with a normal delivery in terms of post-partum health, except for hypertension [adjusted OR = 5.8 (1.9–17.0)], fever [adjusted OR = 1.71 (1.1–2.8)] and infant mortality [adjusted OR = 11.0 (0.8–158.2)]. Women with complications and perinatal death were at increased risk of depression [adjusted OR = 3.4 (1.3–9.0)], urine leakages [adjusted OR = 2.7 (1.2–5.8)], and to report poor health [adjusted OR = 5.27 (2.2–12.4)] and pregnancy’s negative effects on their life [adjusted OR = 4.11 (1.9–9.0)]. Uptake of post-natal services was poor in all groups. Conclusion Women in developing countries face a high risk of severe complications during pregnancy and delivery. These can lead to adverse consequences for their own health and that of their offspring. Resources are needed to ensure that pregnant women receive adequate care before, during and after discharge from hospital. Near-miss women with a perinatal death appear a particularly high-risk group. PMID:20406426

The objective of this study is to evaluate whether therapeutic hypothermia reduces the incidence of acute kidney injury (AKI) among term neonates perinatal asphyxia. This randomized controlled trial conducted in a tertiary care teaching hospital, south India included 120 term neonates with perinatal asphyxia who were randomized to receive either therapeutic hypothermia or standard supportive care. Renal parameters of neonates in both the groups were monitored and AKI was ascertained as per Acute Kidney Injury Network criteria. The incidence of AKI was less in therapeutic hypothermia group compared to standard treatment group (32% versus 60%, p < 0.05). The incidence of Stages 1, 2, and 3 AKI was 22%, 5%, and 5% in therapeutic hypothermia group compared with 52%, 5%, and 3%, respectively, in the standard treatment group. The mortality was less in therapeutic hypothermia group compared with the standard treatment group (26% versus 50%, p < 0.05). Therapeutic hypothermia reduces the incidence and severity of AKI among term neonates with perinatal asphyxia.

Perinatal outcome and the social contract--interrelationships between health and humanity.

Rates of infant mortality and prematurity or low birth weight serve as indirect measures of the health of a nation. This paper presents current population data documenting the still serious problem of perinatal outcome in the United States as well as in other economically developed countries. International comparisons suggest that nations with the greatest inequality of income and social opportunity also have the most adverse perinatal, child, and adult health outcomes. Furthermore, the data assert that these effects are independent of average national wealth or gross national economic productivity. Health status differs by social class and race, even among the most affluent sectors of the population. All social classes, even the wealthiest, suffer the health consequences of social inequalities. An explanatory sociopsychologic theory of causality is proposed.

One hundred and two cases of viable pregnancies with threatened abortion were studied in the department of obstetrics and gynaecology, Kamla Nehru Hospital, IG Medical College, Shimla between November 1987 and February 1989 and their perinatal outcome was evaluated. The pregnancies continued beyond 28 weeks in 61.7% of the cases. The incidence of prematurity was 19.0%. The incidence of low birth weight (LBW) babies was 23.8%. Apgar score was less than 7 in 22.3%. The incidence of neonatal complications was 25.3%. There was no perinatal mortality. In a control group of 50 cases, the incidence of prematurity and LBW was 8% and 4% respectively. Apgar score less than 7 was noted in 4% and neonatal complications were observed only in 4% of newborns.

A hospital based non-experimental comparison of outcome of breech delivery. Ife State Hospitals Complex, Ile-Ife. Two hundred and fourty four singleton breech deliveries occurring at term. They include low 5-minute Apgar score, birth trauma, maternal and perinatal morbidity and mortality. The perinatal mortality was not significantly different in both groups: OR 2.7 (95% C.I. 0.3-26.8). The low 5-minute Apgar scores were higher in the planned vaginal delivery OR 9.0 (95% C.I. 1-73.4), but the traumatic morbidity was not (OR 1.8, 95% C.I. 0.2-20.1). Maternal morbidity occurred more in the planned Caesarean delivery group OR 0.4 (95% C.I. 0.2-0.9). Given appropriate selection criteria and management protocol, the outcome from elective caesarean section might not be better than from planned vaginal delivery.

Perinatal asphyxia remains a significant cause of neonatal mortality and is associated with long-term neurodegenerative disorders. In the present study, we evaluated cellular and subcellular damages to brain development in a model of mild perinatal asphyxia. Survival rate in the experimental group was 67%. One hour after the insult, intraperitoneally injected Evans blue could be detected in the fetuses' brains, indicating disruption of the blood-brain barrier. Although brain mass and absolute cell numbers (neurons and non-neurons) were not reduced after perinatal asphyxia immediately and in late brain development, subcellular alterations were detected. Cortical oxygen consumption increased immediately after asphyxia, and remained high up to 7 days, returning to normal levels after 14 days. We observed an increased resistance to mitochondrial membrane permeability transition, and calcium buffering capacity in asphyxiated animals from birth to 14 days after the insult. In contrast to ex vivo data, mitochondrial oxygen consumption in primary cell cultures of neurons and astrocytes was not altered after 1% hypoxia. Taken together, our results demonstrate that although newborns were viable and apparently healthy, brain development is subcellularly altered by perinatal asphyxia. Our findings place the neonate brain mitochondria as a potential target for therapeutic protective interventions.

This paper examines the beliefs and experiences of women and their families in remote mountain villages of Nepal about perinatal sickness and death and considers the implications of these beliefs for future healthcare provision. Two mountain villages were chosen for this qualitative study to provide diversity of context within a highly disadvantaged region. Individual in-depth interviews were conducted with 42 women of childbearing age and their family members, 15 health service providers, and 5 stakeholders. The data were analysed using a thematic analysis technique with a comprehensive coding process. Three key themes emerged from the study: (1) 'Everyone has gone through it': perinatal death as a natural occurrence; (2) Dewata (God) as a factor in health and sickness: a cause and means to overcome sickness in mother and baby; and (3) Karma (Past deeds), Bhagya (Fate) or Lekhanta (Destiny): ways of rationalising perinatal deaths. Religio-cultural interpretations underlie a fatalistic view among villagers in Nepal's mountain communities about any possibility of preventing perinatal deaths. This perpetuates a silence around the issue, and results in severe under-reporting of ongoing high perinatal death rates and almost no reporting of stillbirths. The study identified a strong belief in religio-cultural determinants of perinatal death, which demonstrates that medical interventions alone are not sufficient to prevent these deaths and that broader social determinants which are highly significant in local life must be considered in policy making and programming.

Several reports recommend the implementation of perinatal regionalization for improvements in maternal and neonatal outcomes, while research evidence on the effectiveness of perinatal regionalization has been limited. The interventional studies have been assessed for robust evidence on the effectiveness of perinatal regionalization on improving maternal and neonatal health outcomes. Bibliographic databases of Medline, EMbase, EconLit, HMIC have been searched using sensitive search terms for interventional studies that reported important patient or process outcomes. At least two authors assessed eligibility for inclusion and the risk of biases and extracted data from the included studies. As meta-analysis was not possible, a narrative analysis as well as a 'vote-counting' analysis has been conducted for important outcomes. After initial screenings 53 full text papers were retrieved. Eight studies were included in the review from the USA, Canada and France. Studies varied in their designs, and in the specifications of the intervention and setting. Only three interrupted time series studies had a low risk of bias, of which only one study reported significant reductions in neonatal and infant mortality. Studies of higher risk of bias were more likely to report improvements in outcomes. Implementing perinatal regionalization programs is correlated with improvements in perinatal outcomes, but it is not possible to establish a causal link. Despite several high profile policy statements, evidence of effect is weak. It is necessary to assess the effectiveness of perinatal regionalization using robust research designs in a more diverse range of countries.

When perinatal medicine emerged as a new medical discipline in the 1960s, Berlin was as one of the world's leading centers. During that time, the city was separated into two parts, each fostering its own health care system. After the destruction of the Berlin Wall, it was possible to speak with the citizens of East Berlin and to access their database systems. This created the singular opportunity to objectively compare the development of perinatal care in both parts of Berlin. Rates of maternal, perinatal, and infant mortality as well as the rate of preterm deliveries were evaluated over time and between East and West Berlin. The timing of introduction of 20 specific perinatal interventions was evaluated across 18 hospitals with more than 500 deliveries (11 in West Berlin and 7 in East Berlin). Interviews were conducted with 100 gynecologists, 100 midwives, and 100 women who had recently delivered their first child from each side of the city regarding their opinions of the importance of these interventions for the quality of perinatal medicine and how they would distribute a budget to improve maternity care. Maternal, perinatal, and infant mortality decreased in both parts of Berlin until 1990 (p < 0.0001), without significant differences between East and West Berlin, though the preterm delivery rate was slightly lower in East Berlin compared with West Berlin (p < 0.06). Some new clinical techniques and treatments--such as cardiotocography, ultrasound, tocolytic therapy, and peridural anesthesia--were introduced earlier in West Berlin. In contrast, certain public health measures--such as maternal transport, screening programs for diabetes, and support of breastfeeding--were introduced much earlier in East Berlin. There were significant differences between the beliefs of gynecologists, midwives, and mothers in East and West Berlin. In general, citizens of East Berlin were more enthusiastic about technological medical advances, whereas citizens of West Berlin were more supportive of public health and alternative methods. In addition, there were significant differences between female and male physicians in their beliefs about how to improve health care, regardless of whether they resided in East or West Berlin. The results of this study may serve as a basis for reflection on how different social circumstances and health care policies can influence the improvement of maternal and child health care.

To study the relation between various perinatal factors and the sequelae of very preterm birth, applying logistic regression analysis. In a nationwide collaborative study in the Netherlands, perinatal and follow up data were collected on 899 liveborn singleton nonmalformed infants with gestational age less than 32 weeks or birthweight less than 1500 g born in 1983. Neonatal mortality rate and total handicap rates (minor and major) in surviving children at two years and five years of age. Comparing breech with vertex presentation, the odds ratio for neonatal mortality (adjusted for duration of pregnancy, birthweight, maternal hypertension and prolonged rupture of membranes) is 1.6 (P < 0.05). Comparing abdominal versus vaginal delivery, the odds ratio indicates equal risks. When breech and vertex presentation are analysed separately it appears that breech presenting infants have a significantly lower mortality risk when born by caesarean section compared with vaginal delivery. However, comparing abdominal versus vaginal delivery in breech presentation, the odds ratio for handicap at five years (0.9) is not significantly different from 1. The data presented suggest a reduced neonatal mortality rate in breech presenting infants born by caesarean section but because of the observational design of the study the statistical analysis described only identifies a possible trend and cannot prove the issue.

Necrotizing enterocolitis is the most lethal gastrointestinal emergency in the neonatal period. Incidence and mortality have remained stable in recent years despite advances in neonatal intensive care. The aim of this study is to show the general characteristics of patients diagnosed with necrotizing enterocolitis at Teresa Herrera's Hospital (La Coruna, Spain) in the last 12years. This study makes a retrospective and prospective descriptive analysis, evaluating the medical records and collecting radiological demographic variables, gestational data, perinatal history, clinical, analytical and perinatal therapeutic management and events in patients diagnosed with and treated for necrotizing enterocolitis between 2003 and 2015. A total of 124 patients met the criteria for inclusion in the study. The mean gestational age of our patients was 33 weeks and remained stable compared with other studies. The average weight of our patients was 1,873g. In our series of cases there was a progressive and significant increase in maternal age and the rate of artificial pregnancies and multiple births. In our series 38.7% of our patients required surgical treatment and the fatality rate was 11.4%. Despite advances in pre- and perinatal care necrotizing enterocolitis represents the leading cause of premature mortality. Incidence has remained unchanged in recent decades. More studies are required to identify both, risk and protective factors to reduce the morbidity and mortality of this entity. Copyright © 2016 Academia Mexicana de Cirugía A.C.

We report baseline results of a community-based randomized trial for improved neonatal survival in Quang Ninh province, Vietnam (NeoKIP; ISRCTN44599712). The NeoKIP trial seeks to evaluate a method of knowledge implementation called facilitation through group meetings at local health centres with health staff and community key persons. Facilitation is a participatory enabling approach that, if successful, is well suited for scaling up within health systems. The aim of this baseline report is to describe perinatal services provided and neonatal outcomes. Survey of all health facility registers of service utilization, maternal deaths, stillbirths and neonatal deaths during 2005 in the province. Systematic group interviews of village health workers from all communes. A Geographic Information System database was also established. Three quarters of pregnant women had ≥3 visits to antenatal care. Two hundred and five health facilities, including 18 hospitals, provided delivery care, ranging from 1 to 3258 deliveries/year. Totally there were 17 519 births and 284 neonatal deaths in the province. Neonatal mortality rate was 16/1000 live births, ranging from 10 to 44/1000 in the different districts, with highest rates in the mountainous parts of the province. Only 8% had home deliveries without skilled attendance, but those deliveries resulted in one-fifth of the neonatal deaths. A relatively good coverage of perinatal care was found in a Vietnamese province, but neonatal mortality varied markedly with geography and level of care. A remaining small proportion of home deliveries generated a substantial part of mortality. © 2010 The Author(s)/Journal Compilation © 2010 Foundation Acta Paediatrica.

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

Despite the clinical impression that firstborn twins do better than second-born twins, recent reports have shown no difference in perinatal mortality between them. In order to evaluate differences in twins, more sensitive means than perinatal deaths are necessary. This study examines differences between 80 firstborn and second-born twin pairs with respect to Apgar score, umbilical venous and arterial blood gas, and acid-base data. The umbilical venous and arterial blood PO2, PCO2, base deficit, pH, and lactic acid concentration were measured in paired samples and compared with the paired t test and chi 2 when applicable. Statistically significant differences favoring twin A, the firstborn, were found in 1-minute Apgar score, umbilical venous pH, PO2, and PCO2, and umbilical arterial PO2. The other factors in umbilical venous and arterial blood did not show statistically significant differences. When these parameters were examined with respect to route of delivery, monochorionic and dichorionic twins, interval between twins, and vertex twins only, with the possible effects of malpresentation eliminated, the results persistently favored the firstborn twin. Thus it is unequivocally demonstrated that there are substantial differences at birth favoring the first twin, despite similar perinatal mortality for both. The data suggest that the second-born twin has potentially greater susceptibility to hypoxia and trauma.

Objective To determine neonatal outcomes (perinatal mortality and special care unit admission) and maternal outcomes (mode of delivery, delivery complications) of elective induction of labour compared with expectant management. Design Retrospective cohort study using an unselected population database. Setting Consultant and midwife led obstetric units in Scotland 1981-2007. Participants 1 271 549 women with singleton pregnancies of 37 weeks or more gestation. Interventions Outcomes of elective induction of labour (induction of labour with no recognised medical indication) at 37, 38, 39, 40, and 41 weeks’ gestation compared with those of expectant management (continuation of pregnancy to either spontaneous labour, induction of labour or caesarean section at a later gestation). Main outcome measures Extended perinatal mortality, mode of delivery, postpartum haemorrhage, obstetric anal sphincter injury, and admission to a neonatal or special care baby unit. Outcomes were adjusted for age at delivery, parity, year of birth, birth weight, deprivation category, and, where appropriate, mode of delivery. Results At each gestation between 37 and 41 completed weeks, elective induction of labour was associated with a decreased odds of perinatal mortality compared with expectant management (at 40 weeks’ gestation 0.08% (37/44 764) in the induction of labour group versus 0.18% (627/350 643) in the expectant management group; adjusted odds ratio 0.39, 99% confidence interval 0.24 to 0.63), without a reduction in the odds of spontaneous vertex delivery (at 40 weeks’ gestation 79.9% (35 775/44 778) in the induction of labour group versus 73.7% (258 665/350 791) in the expectant management group; adjusted odds ratio 1.26, 1.22 to 1.31). Admission to a neonatal unit was, however, increased in association with elective induction of labour at all gestations before 41 weeks (at 40 weeks’ gestation 8.0% (3605/44 778) in the induction of labour group compared with 7.3% (25 572/350 791) in the expectant management group; adjusted odds ratio 1.14, 1.09 to 1.20). Conclusion Although residual confounding may remain, our findings indicate that elective induction of labour at term gestation can reduce perinatal mortality in developed countries without increasing the risk of operative delivery.

A European concerted action (the EuroNatal study) investigated differences in perinatal mortality between countries of Europe. This report describes the methods used in the EuroNatal international audit and discusses the validity of the results. Perinatal deaths between 1993 and 1998 in regions of ten European countries were identified. The categories of death chosen for the study were singleton fetal deaths at 28 or more weeks of gestational age, all intrapartum deaths at 28 or more weeks of gestational age and neonatal deaths at 34 or more weeks of gestational age. Deaths with major congenital anomalies were excluded. An international audit panel used explicit criteria to review all cases, which were blinded for region. Subjective interpretation was used in cases of events or interventions where explicit criteria did not exist. Suboptimal factors were identified in the antenatal, intrapartum and neonatal periods, and classified as 'maternal/social', due to 'infrastructure/service organization', or due to 'professional care delivery'. The contribution of each suboptimal factor to the fatal outcome was listed and consensus was reached on a final grade using a procedure that included correspondence and plenary meetings. In all regions combined, 90% of all known or estimated cases in the selected categories were included in the audit. In total, 1619 cases of perinatal death were audited. Consensus was reached in 1543 (95%) cases. In 75% of all cases, the grade was based on explicit criteria. In the remaining cases, consensus was reached within subpanels without reference to predefined criteria. There was reasonable to good agreement between and within subpanels, and within panel members. The international audit procedure proved feasible and led to consistent results. The results that relate to suboptimal care will need to be studied in depth in order to reach conclusions about their implications for assessing the quality of perinatal care in the individual regions.

Perinatal outcome and later implications of intrauterine growth restriction.

PubMed

Pallotto, Eugenia K; Kilbride, Howard W

2006-06-01

This chapter reviews outcomes for children who have intrauterine growth retardation (IUGR) or small-for-gestation-age (SGA) status at birth. Such infants are at risk for increased perinatal mortality, birth adaptation complications, including perinatal acidosis, hypoglycemia, hypothermia, coagulation abnormalities, and selected immunologic deficiencies. IUGR infants also appear to be at great risk for complications of prematurity, including chronic lung disease and necrotizing enterocolitis. Childhood implications for IUGR include an increased risk for short stature, cognitive delays with decreased academic achievement, and a small but significant increased risk of neurologic disorders, including cerebral palsy. Low socioeconomic status is correlated with the occurrence of IUGR and is significantly related to long-term disabilities. Morbidities associated with preterm delivery appear to be additive to those associated with fetal growth restriction so IUGR, preterm infants may be at great risk for poor neurodevelopmental outcome.

Health apps in low-income countries are emerging tools with the potential to improve quality of health care services, but few apps undergo rigorous scientific evaluation. To determine the effects of the safe delivery app (SDA) on perinatal survival and on health care workers' knowledge and skills in neonatal resuscitation. In a cluster-randomized clinical trial in 5 rural districts of Ethiopia, 73 health care facilities were randomized to the mobile phone intervention or to standard care (control). From September 1, 2013, to February 1, 2015, 3601 women in active labor were included at admission and followed up until 7 days after delivery to record perinatal mortality. Knowledge and skills in neonatal resuscitation were assessed at baseline and at 6 and 12 months after the intervention among 176 health care workers at the included facilities. Analyses were performed based on the intention-to-treat principle. Health care workers in intervention facilities received a smartphone with the SDA. The SDA is a training tool in emergency obstetric and neonatal care that uses visual guidance in animated videos with clinical instructions for management. The primary outcome was perinatal death. Secondary outcomes included the knowledge and clinical management of neonatal resuscitation (skills) of health care workers before the intervention and after 6 and 12 months. The analysis included 3601 women and 176 health care workers. Use of the SDA was associated with a nonsignificant lower perinatal mortality of 14 per 1000 births in intervention clusters compared with 23 per 1000 births in control clusters (odds ratio, 0.76; 95% CI, 0.32-1.81). The skill scores of intervention health care workers increased significantly compared with those of controls at 6 months (mean difference, 6.04; 95% CI, 4.26-7.82) and 12 months (mean difference, 8.79; 95% CI, 7.14-10.45) from baseline, corresponding to 80% and 107%, respectively, above the control level. Knowledge scores also significantly improved in the intervention compared with the control group at 6 months (mean difference, 1.67; 95% CI, 1.02-2.32) and at 12 months (mean difference, 1.54; 95% CI, 0.98-2.09), corresponding to 39% and 38%, respectively, above the control level. The SDA was an effective method to improve and sustain the health care workers' knowledge and skills in neonatal resuscitation as long as 12 months after introduction. Perinatal mortality was nonsignificantly reduced after the intervention. The results are highly relevant in low-income countries, where quality of care is challenged by a lack of continuing education. clinicaltrials.gov Identifier: NCT01945931.

Objective and the context This paper examines the beliefs and experiences of women and their families in remote mountain villages of Nepal about perinatal sickness and death and considers the implications of these beliefs for future healthcare provision. Methods Two mountain villages were chosen for this qualitative study to provide diversity of context within a highly disadvantaged region. Individual in-depth interviews were conducted with 42 women of childbearing age and their family members, 15 health service providers, and 5 stakeholders. The data were analysed using a thematic analysis technique with a comprehensive coding process. Findings Three key themes emerged from the study: (1) ‘Everyone has gone through it’: perinatal death as a natural occurrence; (2) Dewata (God) as a factor in health and sickness: a cause and means to overcome sickness in mother and baby; and (3) Karma (Past deeds), Bhagya (Fate) or Lekhanta (Destiny): ways of rationalising perinatal deaths. Conclusion Religio-cultural interpretations underlie a fatalistic view among villagers in Nepal’s mountain communities about any possibility of preventing perinatal deaths. This perpetuates a silence around the issue, and results in severe under-reporting of ongoing high perinatal death rates and almost no reporting of stillbirths. The study identified a strong belief in religio-cultural determinants of perinatal death, which demonstrates that medical interventions alone are not sufficient to prevent these deaths and that broader social determinants which are highly significant in local life must be considered in policy making and programming.

Objective To explore and compare perinatal and maternal outcomes in women at ‘higher risk’ of complications planning home versus obstetric unit (OU) birth. Design Prospective cohort study. Setting OUs and planned home births in England. Population 8180 ‘higher risk’ women in the Birthplace cohort. Methods We used Poisson regression to calculate relative risks adjusted for maternal characteristics. Sensitivity analyses explored possible effects of differences in risk between groups and alternative outcome measures. Main outcome measures Composite perinatal outcome measure encompassing ‘intrapartum related mortality and morbidity’ (intrapartum stillbirth, early neonatal death, neonatal encephalopathy, meconium aspiration syndrome, brachial plexus injury, fractured humerus or clavicle) and neonatal admission within 48 hours for more than 48 hours. Two composite maternal outcome measures capturing intrapartum interventions/adverse maternal outcomes and straightforward birth. Results The risk of ‘intrapartum related mortality and morbidity’ or neonatal admission for more than 48 hours was lower in planned home births than planned OU births [adjusted relative risks (RR) 0.50, 95% CI 0.31–0.81]. Adjustment for clinical risk factors did not materially affect this finding. The direction of effect was reversed for the more restricted outcome measure ‘intrapartum related mortality and morbidity’ (RR adjusted for parity 1.92, 95% CI 0.97–3.80). Maternal interventions were lower in planned home births. Conclusions The babies of ‘higher risk’ women who plan birth in an OU appear more likely to be admitted to neonatal care than those whose mothers plan birth at home, but it is unclear if this reflects a real difference in morbidity. Rates of intrapartum related morbidity and mortality did not differ statistically significantly between settings at the 5% level but a larger study would be required to rule out a clinically important difference between the groups.

The objective of this study is to answer the question: have we not been doing a lot of caesarean sections at University Teaching Hospital of Dakar? This is an analytic study about caesarean section in 1992, 1996 and 2001; it was a prospective and longitudinal data collection from the epidemiological survey program carried through in Senegal about its obstetrical and surgical cover. For each year concerned, we have analysed caesarean section rate, maternal mortality rate and perinatal mortality rate. To eliminate the random part in observed variation, we used the comparison of proportions observed as a statistical test with a significant threshold less or equal to 5%. Caesarean section has gone from 12% in 1992 to 17.5 in 1996 and 25.2% in 2001. Operative indications are dominated by foeto-pelvic disproportion with an average of 31% and foetal suffering with an average of 25%. The increasing trend has been statistically significant for information's such as foeto-pelvic disproportion and maternal pathologies. The falling trend was statistically significant for indications in relation on relation to foetal suffering and scarred uterus. Gathering information has shown a stabilisation of "obligatory" caesarean rate around 41%, a decrease in "caution" caesarean rate from 50 to 37.2% and an increase in caesarean by "necessity" from 8.6 to 22.4%. The maternal mortality rate among women delivered has fallen from 1.4% to 0.8%, but postoperative surgery morbidity rate was still high around 10%, essentially due to infections. Reading of caesarean section rate has not a significant impact in perinatal prognosis. Today there is an inflation of caesarean section at University Teaching Hospital of Dakar, without any significant loss of the maternal and perinatal mortality rate. The high level of complications due to surgery incite to reverse trends in order to get reasonable rate around 10 to 15% of childbirths.

The objective of this study is to compare the fetal mortality rate (FMR), early neonatal mortality rate (ENMR) and perinatal mortality rate (PMR) of twin and single births. It is based on a survey which was carried out in 22 Hospital Centers in Spain in 1980, and covered 1,956 twins born and 110,734 singletons born. The FMR in twins was 36.3/1000 and 8.8/1000 for singletons. The ENMR in twins was 36.1/1000 and 5.7/1000 for singletons. The PMR in twins was 71.1/1000 and 14.4/1000 for singletons. When birthweight-specific PMR in twin and singletons births are compared, there were no differences between the rates for groups 500-999 g and 1000-1499 g. For birthweight groups of 1500-1999 g (124.4 vs 283.8/1000) and 2000-2999 g (29.6 vs 73.2/1000) the rates for twins were about twice lower than those for single births. The PMR for 2500 g and over birthweight was about twice higher in twins than in singletons (12.5 vs 5.5/1000). After we adjusted for birthweight there was a difference in the FMR (12.6 vs 9.8/1000) and the PMR (19.1 vs 16.0/1000, and no difference in the ENMR between twins and singletons (5.9 vs 6.4/1000), indicating that most of the differences among crude rates are due to differences in distribution of birthweight.

[Perinatal tuberculosis].

PubMed

Sáenz-Gómez, Jessica; Karam Bechara, José; Jamaica Balderas, Lourdes

Perinatal tuberculosis is acquired during birth or during the early neonatal period. Although its incidence is unknown, a search was conducted in Medline and 28 cases were found of perinatal tuberculosis reported from 1983 to 2011. Diagnosis of this disease is important due to having nonspecific symptoms that are mistaken for other infectious diseases. The disease has a high mortality rate (60%); therefore, it requires prompt diagnostic suspicion by the medical staff to prevent a fatal outcome. We describe the case of a 3-month-old male whose 29-year-old mother died of septic shock at 15 days of delivery. The infant's condition began within 30 days of age with cough and difficulty breathing with a diagnosis of multiple foci pneumonia. The infant presented respiratory impairment, meriting change of antibiotics twice, without improvement. The autopsy report of the mother revealed peritoneal tuberculosis. PCR was carried out using tracheal aspirate and pleural fluid of the patient, which were positive for Mycobacterium tuberculosis. Perinatal diagnosis of tuberculosis was established. No hepatic granuloma was found. Perinatal infection should be suspected in children with sepsis and/or pneumonia unresponsive to antibiotics. In this care, the history of tuberculosis in the mother should have oriented the diagnosis. Copyright © 2014 Hospital Infantil de México Federico Gómez. Publicado por Masson Doyma México S.A.

We aim to examine the gendered contexts of poor perinatal survival in the remote mountain villages of Nepal. The study setting comprised two remote mountain villages from a mid-western mountain district of Nepal that ranks lowest on the Human Development Index (0.304), and is reported as having the lowest child survival rates in the country. The findings are taken from a larger study of perinatal survival in remote mountain villages of Nepal, conducted through a qualitative methodological approach within a framework of social constructionist and critical theoretical perspectives. Data were collected through in-depth interviews with 42 women and their families, plus a range of healthcare providers (nurses/auxiliary nurses, female health volunteers, support staff, Auxiliary Health Worker and a traditional healer) and other stakeholders from February to June, 2015. Data were analysed with a comprehensive coding process utilising the thematic analysis technique. The social construction of gender is one of the key factors influencing poor perinatal survival in the villages in this study. The key emerging themes from the qualitative data are: (1) Gendered social construct and vulnerability for poor perinatal survival: child marriages, son preference and repeated child bearing; (2) Pregnancy and childbirth in intra-familial dynamics of relationships and power; and (3) Perception of birth as a polluted event: birth in Gotha (cowshed) and giving birth alone. Motherhood among women of a low social position is central to women and their babies experiencing vulnerabilities related to perinatal survival in the mountain villages. Gendered constructions along the continuum from pre-pregnancy to postnatal (girl settlement, a daughter-in-law, ritual pollution about mother and child) create challenges to ensuring perinatal survival in these villages. It is imperative that policies and programmes consider such a context to develop effective working strategies for sustained reduction of future perinatal deaths.

A systematic review of risk factors for neonatal mortality in adolescent mother's in Sub Saharan Africa.

Worldwide, approximately 14 million mothers aged 15 - 19 years give birth annually. The number of teenage births in Sub Saharan Africa (SSA) is particularly high with an estimated 50% of mothers under the age of 20. Adolescent mothers have a significantly higher risk of neonatal mortality in comparison to adults. The objective of this review was to compare perinatal/neonatal mortality in Sub Saharan Africa and it's associated risk factors between adolescents and adults. We systematically searched six databases to determine risk factors for perinatal/neonatal mortality, and pregnancy outcomes, between adolescent and adults in SSA. Article's quality was assessed and synthesized as a narrative. Being single and having a single parent household is more prevalent amongst adolescents than adults. Nearly all the adolescent mothers (97%) were raised in single parent households. These single life factors could be interconnected and catalyze other risky behaviors. Accordingly, having co-morbidities such as Sexually Transmitted Infections, or not going to school was more prevalent in younger mothers. Inter-generational support for single mothers in SSA communities appears essential in preventing both early pregnancies and ensuring healthy outcomes when they occur during adolescence. Future studies should test related hypothesis and seek to unpack the processes that underpin the relationships between being single and other risk indicators for neonatal mortality in young mothers. Current policy initiatives should account for the context of single African women's lives, low opportunity, status and little access to supportive relationships, or practical help.

Prior studies suggest parental and perinatal risk factors are associated with later offending. It remains uncertain, however, if such risk factors are similarly related to sexual offending. We linked socio-demographic, family relations, and perinatal (obtained at birth) data from the nationwide Swedish registers from 1973 to 2009 with information on criminal convictions of cases and control subjects. Male sex offenders (n = 13 773) were matched 1:5 on birth year and county of birth in Sweden to male controls without sexual or non-sexual violent convictions. To examine risk-factor specificity for sexual offending, we also compared male violent, non-sexual offenders (n = 135 953) to controls without sexual or non-sexual violent convictions. Predictors included parental (young maternal or paternal age at son's birth, educational attainment, violent crime, psychiatric disorder, substance misuse, suicide attempt) and perinatal (number of older brothers, low Apgar score, low birth weight, being small for gestational age, congenital malformations, small head size) variables. Conditional logistic regression models found consistent patterns of statistically significant, small to moderate independent associations of parental risk factors with sons' sexual offending and non-sexual violent offending. For perinatal risk factors, patterns varied more; small for gestational age and small head size exhibited similar risk effects for both offence types whereas a higher number of older biological brothers and any congenital malformation were small, independent risk factors only for non-sexual violence. This nationwide study suggests substantial commonalities in parental and perinatal risk factors for the onset of sexual and non-sexual violent offending.

The purpose of this study was to review systematically the efficacy of transabdominal amnioinfusion (TA) in early preterm premature rupture of membranes (PPROM). We conducted a literature search of EMBASE, MEDLINE, and ClinicalTrials.gov databases and identified studies in which TA was used in cases of proven PPROM and oligohydramnios. Risk of bias was assessed for observational studies and randomized controlled trials. Primary outcomes were latency period and perinatal mortality rates. Four observational studies (n = 147) and 3 randomized controlled trials (n = 165) were eligible. Pooled latency period was 14.4 (range, 8.2-20.6) and 11.41 (range -3.4 to 26.2) days longer in the TA group in the observational and the randomized controlled trials, respectively. Perinatal mortality rates were reduced among the treatment groups in both the observational studies (odds ratio, 0.12; 95% confidence interval, 0.02-0.61) and the randomized controlled trials (odds ratio, 0.33; 95% confidence interval, 0.10-1.12). Serial TA for early PPROM may improve early PPROM-associated morbidity and mortality rates. Additional adequately powered randomized control trials are needed. Copyright © 2012 Mosby, Inc.

Purpose of this study was to determine the frequency of occurence of specific complications of monochorionic diamniotic twins born after 24 weeks of pregnancies and the effect of these complications on perinatal morbidity and mortality. Restrospective analysis. Dpt. of Obstetrics and Gynecology Masaryk University and University Hospital Brno. A retrospective analysis of 175 monochorionic diamniotic pregnancies (mo-bi), which were terminated after the 24th week of pregnancy at the Department of Obstetrics and Gynecology Masaryk University and University Hospital Brno between the years 2008-2013. The specific complications such as twin-to-twin syndrome (TTTs), twin anemia polycytemia sequens (TAPS), selective intrauterine growth restriction (sIUGR), twin-arterial revers perfusion sequence (TRAP), single intrauterine fetal death (IUFD), placental insufficiency with both twins were identified using prenatal ultrasound examinations, perinatal results and the result of pathological anatomical examinations. Perinatal morbidity, neonatal mortality and neurological development were evaluated. The numbers of late detections of specific complications were observed. Specific complications in our group were identified in 50 pregnancies (28.6%). TTTs was diagnosed most often, by 18 pregnancies (10.3%), next most frequent diagnosis were sIUGR (9.7%) and TAPS (3.4%). The placental insufficiency with both twins complicated 2.6% pregnancies. 10 children had abnormal neurological development. Pregnancies with late detection had the worst perinatal results. No acute TTTs during delivery was detected. Specific placental complication reached 29.7% in our file. The most frequent complication was TTTs (10.3%) and selective growth restriction (9.7%). Pregnancies with late diagnosis of these complications had the worst results. The prenatal care by monochorial biamnial pregnancies should be at specialized centres from the 16th week of pregnancy every two weeks.

Context: Hypophosphatasia (HPP) is an inborn error of metabolism that, in its most severe perinatal and infantile forms, results in 50–100% mortality, typically from respiratory complications. Objectives: Our objective was to better understand the effect of treatment with asfotase alfa, a first-in-class enzyme replacement therapy, on mortality in neonates and infants with severe HPP. Design/Setting: Data from patients with the perinatal and infantile forms of HPP in two ongoing, multicenter, multinational, open-label, phase 2 interventional studies of asfotase alfa treatment were compared with data from similar patients from a retrospective natural history study. Patients: Thirty-seven treated patients (median treatment duration, 2.7 years) and 48 historical controls of similar chronological age and HPP characteristics. Interventions: Treated patients received asfotase alfa as sc injections either 1 mg/kg six times per week or 2 mg/kg thrice weekly. Main Outcome Measures: Survival, skeletal health quantified radiographically on treatment, and ventilatory status were the main outcome measures for this study. Results: Asfotase alfa was associated with improved survival in treated patients vs historical controls: 95% vs 42% at age 1 year and 84% vs 27% at age 5 years, respectively (P < .0001, Kaplan-Meier log-rank test). Whereas 5% (1/20) of the historical controls who required ventilatory assistance survived, 76% (16/21) of the ventilated and treated patients survived, among whom 75% (12/16) were weaned from ventilatory support. This better respiratory outcome accompanied radiographic improvements in skeletal mineralization and health. Conclusions: Asfotase alfa mineralizes the HPP skeleton, including the ribs, and improves respiratory function and survival in life-threatening perinatal and infantile HPP. PMID:26529632

Background: Gestational diabetes mellitus (GDM) is emerging as an important public health problem in India owing to its increasing prevalence since the last decade. The issue addressed in the study was whether the management of blood sugar levels in GDM cases can predict maternal and fetal outcomes. Materials and Methods: A prospective cohort study was done for 1 year from October 1, 2013, to September 31, 2014, at 652 diabetic screening units as a part of the Gestational Diabetes Prevention and Control Project approved by the Indian Government in the district of Kanpur, state of Uttar Pradesh. A total of 57,108 pregnant women were screened during their 24–28th weeks of pregnancy by impaired oral glucose test. All types of maternal and perinatal outcomes were followed up in both GDM and non-GDM categories in the 2nd year (2013–2014) after blood sugar levels were controlled. Results: It was seen that for all kinds of maternal and fetal outcomes, the differences between GDM cases and non-GDM cases were highly significant (P < 0.0001, relative risk >1 in every case). Moreover, perinatal mortality also increased significantly from 5.7% to 8.9% when blood sugar levels increased from 199 mg/dl and above. Perinatal and maternal outcomes in GDM cases were also significantly related to the control of blood sugar levels (P < 0.0001). Conclusion: Blood sugar levels can be an indicator of maternal and perinatal morbidity and mortality in GDM cases, provided unified diagnostic criteria are used by Indian laboratories. However, to get an accurate picture on this issue, all factors need further study. PMID:27186155

Is more neonatal intensive care always better? Insights from a cross-national comparison of reproductive care.

Despite high per capita health care expenditure, the United States has crude infant survival rates that are lower than similarly developed nations. Although differences in vital recording and socioeconomic risk have been studied, a systematic, cross-national comparison of perinatal health care systems is lacking. To characterize systems of reproductive care for the United States, Australia, Canada, and the United Kingdom, including a detailed analysis of neonatal intensive care and mortality. Comparison of selected indicators of reproductive care and mortality from 1993-2000 through a systematic review of journal and government publications and structured interviews of leaders in perinatal and neonatal care. Compared with the other 3 countries, the United States has more neonatal intensive care resources yet provides proportionately less support for preconception and prenatal care. Unlike the United States, the other countries provided free family planning services and prenatal and perinatal physician care, and the United Kingdom and Australia paid for all contraception. The United States has high neonatal intensive care capacity, with 6.1 neonatologists per 10 000 live births; Australia, 3.7; Canada, 3.3; and the United Kingdom, 2.7. For intensive care beds, the United States has 3.3 per 10 000 live births; Australia and Canada, 2.6; and the United Kingdom, 0.67. Greater neonatal intensive care resources were not consistently associated with lower birth weight-specific mortality. The relative risk (United States as reference) of neonatal mortality for infants <1000 g was 0.84 for Australia, 1.12 for Canada, and 0.99 for the United Kingdom; for 1000 to 2499 g infants, the relative risk was 0.97 for Australia, 1.26 for Canada, and 0.95 for the United Kingdom. As reported elsewhere, low birth weight rates were notably higher in the United States, partially explaining the high crude mortality rates. The United States has significantly greater neonatal intensive care resources per capita, compared with 3 other developed countries, without having consistently better birth weight-specific mortality. Despite low birth weight rates that exceed other countries, the United States has proportionately more providers per low birth weight infant, but offers less extensive preconception and prenatal services. This study questions the effectiveness of the current distribution of US reproductive care resources and its emphasis on neonatal intensive care.

The outcome of pregnancy after threatened abortion.

Hertz, J B; Heisterberg, L

1985-01-01

A prospectively collected group of 93 pregnancies complicated by threatened abortion was carefully monitored throughout pregnancy, during birth and in the perinatal period, and any deviation from a completely uneventful course was registered. Comparison was made with a selected group of 282 non-risk pregnant women. A significant association was found between threatened abortion and the overall number of complications in the second half of pregnancy requiring medical intervention and/or admission to hospital, impending pre-term birth requiring betamimetics, pre-term birth, retention of the placenta, birth weight below 2000 g, light-for-dates infants in case of pre-term birth or birth weight below 2000 g, and hyperbilirubinemia in infants with birth weight below 2000 g. The incidences of perinatal mortality and congenital malformations did not differ significantly from those of the control group. Pregnancies complicated by threatened abortion constitute a risk group requiring careful obstetric and perinatal supervision and follow-up.

Yunnan province is located in south western China and is one of the poorest provinces of the country. This study examines the premature mortality burden from common causes of deaths among an urban region, suburban region and rural region of Kunming, the capital of Yunnan. Years of life lost (YLL) rate per 1,000 and mortality rate per 100,000 were calculated from medical death certificates in 2003 and broken down by cause of death, age and gender among urban, suburban and rural regions. YLL was calculated without age-weighting and discounting rate. Rates were age-adjusted to the combined population of three regions. However, 3% discounting rate and a standard age-weighting function were included in the sensitivity analysis. Non-communicable diseases contributed the most YLL in all three regions. The rural region had about 50% higher premature mortality burden compared to the other two regions. YLL from infectious diseases and perinatal problems was still a major problem in the rural region. Among non-communicable diseases, YLL from stroke was the highest in the urban/suburban regions; COPD followed as the second and was the highest in the rural region. Mortality burden from injuries was however higher in the rural region than the other two regions, especially for men. Self-inflicted injuries were between 2-8 times more serious among women. The use of either mortality rate or YLL gives a similar conclusion regarding the order of priority. Reanalysis with age-weighting and 3% discounting rate gave similar results. Urban south western China has already engaged in epidemiological pattern of developed countries. The rural region is additionally burdened by diseases of poverty and injury on top of the non-communicable diseases.

To study the effect of travel time, at the start or during labour, from home to hospital on mortality and adverse outcomes in pregnant women at term in primary and secondary care. Population-based cohort study from 2000 up to and including 2006. The Netherlands Perinatal Registry. A total of 751,926 singleton term hospital births. We assessed the impact of travel time by car, calculated from the postal code of the woman's residence to the 99 maternity units, on neonatal outcome. Logistic regression modelling with adjustments for gestational age, maternal age, parity, ethnicity, socio-economic status, urbanisation, tertiary care centres and volume of the hospital was used. Mortality (intrapartum, and early and late neonatal mortality) and adverse neonatal outcomes (mortality, Apgar <4 and/or admission to a neonatal intensive care unit). The mortality was 1.5 per 1000 births, and adverse outcomes occurred in 6.0 per 1000 births. There was a positive relationship between longer travel time (≥20 minutes) and total mortality (OR 1.17, 95% CI 1.002-1.36), neonatal mortality within 24 hours (OR 1.51, 95% CI 1.13-2.02) and with adverse outcomes (OR 1.27, 95% CI 1.17-1.38). In addition to travel time, both delivery at 37 weeks of gestation (OR 2.23, 95% CI 1.81-2.73) or 41 weeks of gestation (OR 1.52, 95% CI 1.29-1.80) increased the risk of mortality. A travel time from home to hospital of 20 minutes or more by car is associated with an increased risk of mortality and adverse outcomes in women at term in the Netherlands. These findings should be considered in plans for the centralisation of obstetric care. © 2010 The Authors Journal compilation © RCOG 2010 BJOG An International Journal of Obstetrics and Gynaecology.

To describe the characteristics, the immediate and short-term outcome and predictors of mortality in normal-birth-weight (NBW) infants admitted to a tertiary neonatal intensive care unit (NICU) in Singapore. We retrospectively reviewed the medical records of 137 consecutive NBW infants admitted to the NICU of the Singapore General Hospital from January 1991 to December 1992. Data on the diagnoses, clinical presentation of illness, intervention received, complications and outcome as well as follow-up patterns for the first 2 years of life, were collected and analysed. NBW NICU infants comprised 1.8% of births in our hospital and 40.8% of all NICU admissions. The main reasons for NICU admissions were respiratory disorders (61.3%), congenital anomalies (15.3%) and asphyxia neonatorum (11.7%). Respiratory support was necessary in 81.8%. Among those ventilated, the only predictive factor contributing to mortality was the mean inspired oxygen concentration. The mortality rate was 11.7%. Causes of death included congenital anomalies (43.75%), asphyxia neonatorum (31.25%) and pulmonary failure secondary to meconium aspiration syndrome (12.5%). The median hospital stay among survivors (88.3%) was 11.0 (range, 4 to 70) days. Of 42 patients (out of 117 survivors) who received follow-up for at least 6 months, 39 infants did not have evidence of any major neurodevelopmental abnormalities at their last follow-up visit, prior to or at 2 years of age. Despite their short hospital stay (compared to very-low-birth-weight infants), the high volume of NBW admissions make the care of this population an important area for review to enhance advances in and hence, reduce the cost of NICU care. With improved antenatal diagnostic techniques (allowing earlier and more accurate diagnosis of congenital malformations) and better antenatal and perinatal care (allowing better management of at-risk pregnancies), it is anticipated that there should be a reduction in such admissions with better outcomes. Close follow-up of this high-risk group of infants is also important in order to offer early intervention to those who may possibly have perinatally-related developmental difficulties.

1999-01-01

The aim of this study was to assess the contribution of current obstetrical practice to the occurrence and complications of umbilical cord prolapse. Maternal and neonatal charts of 87 pregnancies complicated by true umbilical cord prolapse during a 5-year period were reviewed. Twin gestation and noncephalic presentations were common features (14 and 41%, respectively). Eighty-nine percent (77) of infants were delivered by cesarean section of which 29% were classical and 88% were primary. The mean gestational age at delivery was 34.0 +/- 6.0 weeks, and the mean birth weight was 2318 +/- 1159 g. Obstetrical intervention preceded 41 (47%) cases (the obstetrical intervention group): amniotomy (9), scalp electrode application (4), intrauterine pressure catheter insertion (6), attempted external cephalic version (7), expectant management of preterm premature rupture of membranes (14), manual rotation of the fetal head (1), and amnioreduction (1). There were 11 perinatal deaths. Thirty-three percent of the infants (32) had a 5-min Apgar score < 7 and 34% had a cord pH < 7.20. Neonatal seizures, intracerebral hemorrhage, necrotizing enterocolitis, hyaline membrane disease, persistent fetal circulation, sepsis, assisted ventilation, and perinatal mortality were comparable in the "obstetrical intervention" and "no-intervention" groups. Most of the neonatal complications occurred in infants < 32 weeks' gestation. We conclude that obstetrical intervention contributes to 47% of umbilical cord prolapse cases; however, it does not increase the associated perinatal morbidity and mortality.

Super-obesity is associated with significantly elevated rates of obstetric complications, adverse perinatal outcomes and interventions. The purpose of this study was to determine the prevalence, risk factors, management and perinatal outcomes of super-obese women giving birth in Australia. A national population-based cohort study. Super-obese pregnant women (body mass index (BMI) >50 kg/m(2) or weight >140 kg) who gave birth between January 1 and October 31, 2010 and a comparison cohort were identified using the Australasian Maternity Outcomes Surveillance System (AMOSS). Outcomes included maternal and perinatal morbidity and mortality. Prevalence estimates calculated with 95% confidence intervals (CIs). Adjusted odds ratios (ORs) were calculated using multivariable logistic regression. 370 super-obese women with a median BMI of 52.8 kg/m(2) (range 40.9-79.9 kg/m(2)) and prevalence of 2.1 per 1 000 women giving birth (95% CI: 1.96-2.40). Super-obese women were significantly more likely to be public patients (96.2%), smoke (23.8%) and be socio-economically disadvantaged (36.2%). Compared with other women, super-obese women had a significantly higher risk for obstetric (adjusted odds ratio (AOR) 2.42, 95% CI: 1.77-3.29) and medical (AOR: 2.89, 95% CI: 2.64-4.11) complications during pregnancy, birth by caesarean section (51.6%) and admission to special care (HDU/ICU) (6.2%). The 372 babies born to 365 super-obese women with outcomes known had significantly higher rates of birthweight ≥ 4500 g (AOR 19.94, 95 % CI: 6.81-58.36), hospital transfer (AOR 3.81, 95 % CI: 1.93-7.55) and admission to Neonatal Intensive Care Unit (NICU) (AOR 1.83, 95% CI: 1.27-2.65) compared to babies of the comparison group, but not prematurity (10.5% versus 9.2%) or perinatal mortality (11.0 (95% CI: 4.3-28.0) versus 6.6 (95% CI: 2.6- 16.8) per 1 000 singleton births). Super-obesity in pregnancy in Australia is associated with increased rates of pregnancy and birth complications, and with social disadvantage. There is an urgent need to further address risk factors leading to super-obesity among pregnant women and for maternity services to better address pre-pregnancy and pregnancy care to reduce associated inequalities in perinatal outcomes.

Perinatal asphyxia is one of the main causes of perinatal mortality and morbidity worldwide and it generates high costs for health systems; however, it has modifiable risk factors. To identify the risk factors associated with the development of perinatal asphyxia in newborns at Hospital Universitario del Valle, Cali, Colombia. Incident cases and concurrent controls were examined. Cases were defined as newborns with moderate to severe perinatal asphyxia who were older than or equal to 36 weeks of gestational age, needed advanced resuscitation and presented one of the following: early neurological disorders, multi-organ commitment or a sentinel event. The controls were newborns without asphyxia who were born one week apart from the case at the most and had a comparable gestational age. Patients with major congenital malformations and syndromes were excluded. Fifty-six cases and 168 controls were examined. Premature placental abruption (OR=41.09; 95%CI: 4.61-366.56), labor with a prolonged expulsive phase (OR=31.76; 95%CI: 8.33-121.19), lack of oxytocin use (OR=2.57; 95% CI: 1.08 - 6.13) and mothers without a partner (OR=2.56; 95% CI: 1.21-5.41) were risk factors for the development of perinatal asphyxia in the study population. Social difficulties were found in a greater proportion among the mothers of cases. Proper control and monitoring of labor, development of a thorough partograph, and active searches are recommended to ensure that all pregnant women have adequate prenatal care with the provision of social support to reduce the frequency and negative impact of perinatal asphyxia.

Dietary copper (Cu) deficiency was induced perinatally in Swiss Albino mice and postnatally in male Holtzman rats to investigate the effect of L-threo 3,4-dihydroxyphenylserine (DOPS) on pup survival and catecholamine levels in a 2 × 2 factorial design. Mouse dams were placed on one of four treatments 14 days after mating and rats at postnatal day 19 (P19). Treatments were Cu-adequate (Cu +) and Cu-deficient (Cu −) diets with or without DOPS (1 mg/ml) in the drinking water. Mouse pups were killed at P14 and rats at P49. Mortality in Cu − pups was 46% and not significantly improved by DOPS, 39%. A repeat study with mice adding ascorbic acid in the water with DOPS showed no improvement. Compared to Cu + animals, Cu − animals were smaller, anemic and had a 92% reduction in liver Cu. DOPS treatment made no improvement to and in some cases exacerbated the Cu deficiency. Catecholamine levels measured in heart and brain by LCEC showed decreased NE levels and increased DA levels in Cu − animals compared to controls. DOPS treatment did not alter this pattern. Although DOPS was present in treated animal’s tissues, survival in mice and catecholamine levels in mice and rats were not altered by the 1 mg/ml dose of DOPS. PMID:16117185

Kaneko, K

To clarify the effects of perinatal anoxia on the subsequent amino acid metabolism in the brain of children, free amino acid levels in the cerebrospinal fluid (CSF) were determined in 15 children diagnosed as having cerebral palsy and/or mental retardation with perinatal anoxia, and 58 control children without anoxia, aged from 4 days to 12 yrs. There was no significant difference in total amino acid levels between anoxic children and the controls. In the controls, the Gln level in CSF was high, Arg, Asp and Glu levels in CSF were almost the same during infancy and childhood, and the levels of Orn, Lys, His, Tau, Thr, Ser, Asn, Gly, Ala, Val, Met, Ile, Leu, Tyr and Phe in CSF decreased with age until pre-school age. In the newborns and infants among the anoxic children, the levels of most free amino acids in CSF were relatively high compared with those of the controls and, except Glu and Gln, decreased with age during infancy. The Orn, His, Gly, Tyr and Phe levels in CSF of anoxic children were lower than those of the controls in older infants. These results suggest that perinatal anoxia affected free amino acid patterns in CSF of newborns and infants and that the subsequent disturbance of amino acid metabolism in their brains remained after birth.

Perinatal Mood and Anxiety Disorders (PMAD) are common and can cause significant morbidity and mortality for mother and child. A healthy perinatal period requires significant adaptations; however, systems can become imbalanced resulting in depressive and anxiety symptoms. The interface between the microbiome, the immune system, and the stress system may be a model for understanding mechanisms underlying PMAD. Emerging literature from general populations regarding immune, hormone, and HPA axis changes in relation to the microbiome combined with literature on immune, gonadotropin, and stress systems in the perinatal period provides a background. We systematically investigated literature in the developing field of the microbiome in relation to PMAD. Our inclusion criteria were 1) reporting measure of maternal mood, stress, or anxious or depressed behavior; 2) in the perinatal period, defined as pregnancy through one year postpartum; and 3) reporting measure of maternal microbiome including manipulations of the microbiome through prebiotics, probiotics, or interventions with microbial byproducts. The review identified research studying associations between stress and maternal microbiome; dietary impacts on microbial composition, mood, and stress; and the relationship between the microbiome and the immune system through immunoregulatory mechanisms. Important themes identified include: the importance of studying the maternal microbiome and measures of stress, anxiety, and depression and that multi-hit models will be needed as research strives to determine the effects of multiple mechanisms working in concert.

2006-09-01

We sought to assess the effects of fracture injuries on maternal and fetal/neonatal outcomes in a large obstetric population. We performed a retrospective cohort study using a database in which maternal and neonatal hospital discharge summaries were linked with birth and death certificates to identify any relation between maternal fractures and maternal and perinatal morbidity. Fracture injuries and perinatal outcomes were identified with the use of the International Classification of Diseases, 9th revision, Clinical Modification codes. Outcomes were further subdivided on the basis of anatomic site of fracture. A total of 3292 women with > or = 1 fractures were identified. Maternal mortality (odds ratio, 169 [95% CI, 83.2,346.4]) and morbidity (abruption and blood transfusion) rates were increased significantly in women who were delivered during hospitalization for their injury. Women who were discharged undelivered continued to have delayed morbidity, which included a 46% increased risk of low birth weight infants (odds ratio, 1.5 [95% CI, 1.3,1.7]) and a 9-fold increased risk of thrombotic events (odds ratio, 9.2 [95% CI, 1.3,65.7]) Pelvic fractures had the worst outcomes. Fractures during pregnancy are an important marker for poor perinatal outcomes.

Objectives Healthcare providers in low-resource settings confront high rates of perinatal mortality. How providers cope with such challenges can affect their well-being and patient care; we therefore sought to understand how physicians and midwives make sense of and cope with these deaths. Methods We conducted semi-structured interviews with midwives, obstetrician-gynecologists, pediatricians and trainee physicians at a large teaching hospital in Kumasi, Ghana. Interviews focused on participants' coping strategies surrounding perinatal death. We identified themes from interview transcripts using qualitative content analysis. Results Thirty-six participants completed the study. Themes from the transcripts revealed a continuum of control/self-efficacy and engagement with the deaths. Providers demonstrated a commitment to push on with their work and provide the best care possible. In select cases, they described the transformative power of attitude and sought to be agents of change. Conclusions Physicians and midwives in a low-resource country in sub-Saharan Africa showed remarkable resiliency in coping with perinatal death. Still, future work should focus on training clinicians in coping and strengthening their self-efficacy and engagement.

Perinatal outcome in relation to fetal sex in offspring to mothers with pre-gestational and gestational diabetes--a population-based study.

The objective of the present study was to investigate if perinatal outcome differs with fetal sex in pregnancies with maternal Type 1 diabetes, Type 2 diabetes or gestational diabetes. This was a population-based cohort study, with data from the Medical Birth Registry in Sweden throughout the period 1998-2007. Singleton pregnancies with maternal Type 1 diabetes (n = 4092), Type 2 diabetes (n = 412) and gestational diabetes (n = 8602) were identified based on the International Classification of Diseases, 10th edition code. For comparison, 905 565 pregnancies without diabetes were included. The primary outcome was a composite outcome, consisting of any of the following diagnoses: perinatal mortality rate, major malformation, preterm delivery, acute respiratory disorders and neonatal hypoglycaemia. Logistic regression was used to obtain odds ratios for adverse outcomes in male offspring within the diabetic and reference cohorts, respectively. In pregnancies with diabetes, maternal characteristics did not differ with fetal sex, except for a higher rate of Caesarean delivery in male offspring of women with Type 1 diabetes. Male infants to mothers with Type 1 diabetes and gestational diabetes had significantly increased odds of respiratory disorders [adjusted odds ratio (confidence interval) Type 1 diabetes: 1.50 (1.12-2.02); gestational diabetes: 1.81 (1.27-2.57)]. Male infants to mothers with gestational diabetes also had significantly increased odds of major malformations [adjusted odds ratio: 1.44 (1.07-1.93)]. In offspring of mothers with Type 2 diabetes, odds ratios of most outcomes were higher in male infants; however, not significantly different from female infants. In pregnancies without diabetes, male infants had significantly higher odds of all adverse outcomes, except perinatal mortality rate. The risk of adverse perinatal outcome in offspring of mothers with Type 1 diabetes and gestational diabetes did not differ by sex, except for a higher risk in male infants for respiratory disorders. The risk of major malformations was also significantly increased in male offspring to mothers with gestational diabetes. In offspring of mothers with Type 2 diabetes, no significant differences between sexes were found. © 2014 The Authors. Diabetic Medicine © 2014 Diabetes UK.

Neuroprotective actions of perinatal choline nutrition

PubMed Central

Blusztajn, Jan Krzysztof; Mellott, Tiffany J.

2017-01-01

Choline is an essential nutrient for humans. Studies in rats and mice have shown that high choline intake during gestation or the perinatal period improves cognitive function in adulthood, prevents memory decline of old age, and protects the brain from damage and cognitive and neurological deterioration associated with epilepsy and hereditary conditions such as Down’s and Rett syndromes. These behavioral changes are accompanied by modified patterns of expression of hundreds of cortical and hippocampal genes including those encoding proteins central for learning and memory processing. The effects of choline correlate with cerebral cortical changes in DNA and histone methylation, thus suggesting an epigenomic mechanism of action of perinatal choline. PMID:23314544

To develop a standardized process of perinatal mortality audit (PMA) and improve the capacity of health workers to identify and correct factors underlying preventable deaths in Fiji. In a pilot study, clinicians and healthcare managers in obstetrics and pediatrics were trained to investigate stillbirths and neonatal deaths according to current guidelines. A pre-existing PMA datasheet was refined for use in Fiji and trialed in three divisional hospitals in 2011-12. Key informant interviews identified factors influencing PMA uptake. Overall, 141 stillbirths and neonatal deaths were analyzed (57 from hospital A and 84 from hospital B; forms from hospital C excluded because incomplete/illegible). Between-site variations in mortality were recorded on the basis of the level of tertiary care available; 28 (49%) stillbirths were recorded in hospital A compared with 53 (63%) in hospital B. Substantial health system factors contributing to preventable deaths were identified, and included inadequate staffing, problems with medical equipment, and lack of clinical skills. Leadership, teamwork, communication, and having a standardized process were associated with uptake of PMA. The use of PMAs by health workers in Fiji and other Pacific island countries could potentially rectify gaps in maternal and neonatal service delivery.

Background Delays in receiving effective care during labor and at birth may be fatal for the mother and fetus, contributing to 2 million annual intrapartum stillbirths and intrapartum-related neonatal deaths each year. Objective We present a systematic review of strategies to link families and facilities, including community mobilization, financial incentives, emergency referral and transport systems, prenatal risk screening, and maternity waiting homes. Results There is moderate quality evidence that community mobilization with high levels of community engagement can increase institutional births and significantly reduce perinatal and early neonatal mortality. Meta-analysis showed a doubling of skilled birth attendance and a 35% reduction in early neonatal mortality. However, no data are available on intrapartum-specific outcomes. Evidence is limited, but promising, that financial incentive schemes and community referral/transport systems may increase rates of skilled birth attendance and emergency obstetric care utilization; however, impact on mortality is unknown. Current evidence for maternity waiting homes and risk screening is low quality. Conclusions Empowering communities is an important strategy to reduce the large burden of intrapartum complications. Innovations are needed to bring the poor closer to obstetric care, such as financial incentives and cell phone technology. New questions need to be asked of “old” strategies such as risk screening and maternity waiting homes. The effect of all of these strategies on maternal and perinatal mortality, particularly intrapartum-related outcomes, requires further evaluation. PMID:19815201

Understanding the causes of under-five deaths is key to realizing sustainable developmental goals. The aim of this descriptive study was to investigate the causes of under-five mortality in İstanbul during 2011 and compare the findings to those of 1988 and 2000. All burial records of İstanbul were evaluated, and cemetery records of 1494 children, who died at under five years of age and were buried in İstanbul Metropolitan Municipality Cemeteries between 1 January and 31 December 2011, were analyzed. Several sociodemographic characteristics and causes of death were compared with the results of studies carried out in 1988 and 2000 in İstanbul with similar methods. Under-five mortality rate was lower in 2011 than in 1988 and 2000. Of all deaths, 58.8% had occurred in the neonatal period and most were in the first day of life, similarly to those of 1988 and 2000. The proportion of deaths in the age group of 1-4 years was found to be increasing. Prematurity and perinatal causes remained the main cause of death under five years of age in İstanbul during the 23-year period. Unknown causes, due to misclassification, were still seen in a relatively high proportion. Under-five mortality rate and death due to infectious diseases decreased in İstanbul from 1988 to 2011. Our findings showed a need for more emphasis on perinatal events and better evaluation of causes of death in clinical practice.

Ethnic patterns of hypospadias in New Zealand do not resemble those observed for cryptorchidism and testicular cancer: evidence of differential aetiology?

It has been proposed that hypospadias, cryptorchidism, poor semen quality and testicular cancer might share common prenatal causes. We have previously demonstrated similar ethnic patterns for the incidence of testicular cancer and cryptorchidism - a known risk factor for testicular cancer. If the underlying exposure(s) that cause hypospadias, cryptorchidism and testicular cancer are shared, then we would expect the incidence relationship between ethnic groups to follow the same pattern across all three conditions. We followed a birth cohort of 318 345 eligible male neonates born in New Zealand between 2000-2010, and linked routinely collected maternity records with inpatient hospitalization and mortality records through to 2011. We searched hospitalization records for diagnoses of hypospadias, and used mortality records for censoring. We used Poisson regression methods to compare the relative risk of hypospadias between ethnic groups, adjusting for perinatal risk factors and total person time. We observed that European/Other children had the highest risk of hypospadias, with Māori, Pacific and Asian boys having around 40% lower risk of disease compared with this group (adjusted relative risk [RR]: Māori 0.62, 95% CI 0.55-0.70; Pacific 0.62, 95% CI 0.53-0.72; Asian 0.57, 95% CI 0.47-0.69). This contrasts substantially with our previous observations for cryptorchidism and testicular cancer, where Māori males have the greatest risk. Our observations suggest that - at least in New Zealand - the exposures that drive the development of hypospadias may differ to those that that drive the development of cryptorchidism and/or testicular cancer. © 2015 American Society of Andrology and European Academy of Andrology.

Reducing perinatal mortality among Indigenous babies in Queensland: should the first priority be better primary health care or better access to hospital care during confinement?

PubMed

Johnston, Trisha; Coory, Michael

2005-05-27

The perinatal mortality rate among Indigenous Australians is still double that of the rest of the community. The aim of our study was to estimate the extent to which increased risk of low birthweight and preterm birth among Indigenous babies in Queensland account for their continuing mortality excess. If a large proportion of excess deaths can be explained by the unfavourable birthweight and gestational age distribution of Indigenous babies, then that would suggest that priority should be given to implementing primary health care interventions to reduce the risk of low birthweight and preterm birth (eg, interventions to reduce maternal smoking or genitourinary infections). Conversely, if only a small proportion is explained by birthweight and gestational age, then other strategies might need to be considered such as improving access to high-quality hospital care around the time of confinement. Population-based, descriptive study of perinatal mortality rates among Indigenous and non-Indigenous babies, in Queensland, stratified by birthweight and gestational age. Indigenous babies are twice as likely to die as their non-Indigenous counterparts (rate ratio1998-2002: 2.01; 95%ci 1.77, 2.28). However, within separate strata of birth weight and gestational age, Indigenous and non-Indigenous rates are similar. The Mantel-Haenszel rate ratio adjusted for birth weight and gestational age was 1.13 (0.99, 1.28). This means that most of the excess mortality in Indigenous babies is largely due to their unfavourable birth weight and gestational-age distributions. If Indigenous babies had the same birth weight and gestational age distribution as their non-Indigenous counterparts, then the relative disparity would be reduced by 87% and 20 fewer Indigenous babies would die in Queensland each year. Our results suggest that Indigenous mothers at high risk of poor outcome (for example those Indigenous mothers in preterm labour) have good access to high quality medical care around the time of confinement. The main reason Indigenous babies have a high risk of death is because they are born too early and too small. Thus, to reduce the relative excess of deaths among Indigenous babies, priority should be given to primary health care initiatives aimed at reducing the prevalence of low birth weight and preterm birth.

The importance of fetal gender in intrauterine growth restriction

PubMed Central

Radulescu, L; Ferechide, D; Popa, F

2013-01-01

One of the most important causes of perinatal mortality and morbidity complicating significant percentage pregnancies is intrauterine growth restriction (IUGR). Fetal growth restriction is the main cause of intrauterine fetal death and the second leading cause of death in the neonatal period. Numerous studies in different populations reveal an association between intrauterine growth restriction and perinatal and postnatal developments, which differ according to the sex of newborns with intrauterine growth restriction. However, the mechanisms of intrauterine programming, the critical time necessary to cause injury and involvement of other factors are unclear and although several authors’ opinions differ, it seems that females are more likely to develop intrauterine growth restriction.

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.

An unusual mortality event (UME) involving primarily common bottlenose dolphins Tursiops truncatus of all size classes stranding along coastal Louisiana, Mississippi, and Alabama, USA, started in early 2010 and continued into 2014. During this northern Gulf of Mexico UME, a distinct cluster of perinatal dolphins (total body length <115 cm) stranded in Mississippi and Alabama during 2011. The proportion of annual dolphin strandings that were perinates between 2009 and 2013 were compared to baseline strandings (2000-2005). A case-reference study was conducted to compare demographics, histologic lesions, and Brucella sp. infection prevalence in 69 UME perinatal dolphins to findings from 26 reference perinates stranded in South Carolina and Florida outside of the UME area. Compared to reference perinates, UME perinates were more likely to have died in utero or very soon after birth (presence of atelectasis in 88 vs. 15%, p < 0.0001), have fetal distress (87 vs. 27%, p < 0.0001), and have pneumonia not associated with lungworm infection (65 vs. 19%, p = 0.0001). The percentage of perinates with Brucella sp. infections identified via lung PCR was higher among UME perinates stranding in Mississippi and Alabama compared to reference perinates (61 vs. 24%, p = 0.01), and multiple different Brucella omp genetic sequences were identified in UME perinates. These results support that from 2011 to 2013, during the northern Gulf of Mexico UME, bottlenose dolphins were particularly susceptible to late-term pregnancy failures and development of in utero infections including brucellosis.

Right Ventricular Myocardial Ischemia with Arrhythmia in an Asphyxiated Newborn

2016-01-01

Background Infant and neonatal myocardial infarction (MI) has been described in association with congenital heart disease, coronary artery abnormalities, myocarditis, and tumors. MI in the perinatal period in a structurally normal heart and with ventricular arrhythmia as a presenting feature has not been thoroughly described. Published case reports describe treatment methods extrapolated from adult MI. However, due to the rare occurrence, the most appropriate acute treatment for both MI and ventricular arrhythmia in newborn infants remains unknown. Case A male term infant with perinatal asphyxia and need for extensive cardiopulmonary resuscitation at birth had ventricular tachyarrhythmia and ST-elevations on electrocardiogram. Four hours after birth, he died from cardiogenic failure. A thrombus at the right coronary artery was found on autopsy. Conclusion MI in the perinatal period in a structurally normal heart is very rare and mortality is high. Although acute treatments extrapolated from adult MI has been described to result in favorable outcomes in newborn infants, guidelines are lacking on how to manage acute MI and associated ventricular arrhythmia.

One of the most common causes of mortality and morbidity in children is perinatal hypoxia-ischemia (HI). In spite of the advances in neonatology, its incidence is not diminishing, generating a pediatric population that will require an extended amount of chronic care throughout their lifetime. For this reason, new and more effective neuroprotective strategies are urgently required, in order to minimize as much as possible the neurological consequences of this encephalopathy. In this sense, interest has grown in the neuroprotective possibilities of melatonin, as this hormone may help to maintain cell survival through the modulation of a wide range of physiological functions. Although some of the mechanisms by which melatonin is neuroprotective after neonatal asphyxia remain a subject of investigation, this review tries to summarize some of the most recent advances related with its use as a therapeutic drug against perinatal hypoxic-ischemic brain injury, supporting the high interest in this indoleamine as a future feasible strategy for cerebral asphyctic events.

Wildfire activity is predicted to increase in many parts of the world due to changes in temperature and precipitation patterns from global climate change. Wildfire smoke contains numerous hazardous air pollutants and many studies have documented population health effects from this exposure. We aimed to assess the evidence of health effects from exposure to wildfire smoke and to identify susceptible populations. We reviewed the scientific literature for studies of wildfire smoke exposure on mortality and on respiratory, cardiovascular, mental, and perinatal health. Within those reviewed papers deemed to have minimal risk of bias, we assessed the coherence and consistency of findings. Consistent evidence documents associations between wildfire smoke exposure and general respiratory health effects, specifically exacerbations of asthma and chronic obstructive pulmonary disease. Growing evidence suggests associations with increased risk of respiratory infections and all-cause mortality. Evidence for cardiovascular effects is mixed, but a few recent studies have reported associations for specific cardiovascular end points. Insufficient research exists to identify specific population subgroups that are more susceptible to wildfire smoke exposure. Consistent evidence from a large number of studies indicates that wildfire smoke exposure is associated with respiratory morbidity with growing evidence supporting an association with all-cause mortality. More research is needed to clarify which causes of mortality may be associated with wildfire smoke, whether cardiovascular outcomes are associated with wildfire smoke, and if certain populations are more susceptible.

Preventable infant deaths, lone births and lack of registration in Mexican indigenous communities: health care services and the afterlife of colonialism.

PubMed

Gamlin, Jennie; Osrin, David

2018-06-19

Mexico's indigenous communities continue to experience higher levels of mortality and poorer access to health care services than non-indigenous regions, a pattern that is repeated across the globe. We conducted a two-year ethnographic study of pregnancies and childbirth in an indigenous Wixárika community to explore the structural causes of this excess mortality. In the process we also identified major differences between official infant mortality rates, and the numbers of infants born to women in our sample who did not survive. We interviewed 67 women during pregnancy and followed-up after the birth of their child. At baseline, socio-demographic data was collected as well as information regarding birthing intentions. In depth-interviews and semi-structured interviews were conducted with 62 of these women after the birth of their child, using a checklist of questions. Women were asked about choices regarding, and experiences of childbirth. Of the 62 women we interviewed at follow-up 33 gave birth at home without skilled attendance and five gave birth completely alone in their homes. Five neonates died during labour or the perinatal period. Concerns about human resources, the structure of service delivery and unwanted interventions during childbirth all appear to contribute to the low institutional childbirth rate. Our data also suggests a low rate of death registration, with the custom of burying infants where they die. This excess mortality, occurring in the context of unnecessary lone and unassisted childbirth are structurally generated forms of violence.

This systematic review investigates the effect of the birth center setting on neonatal mortality in economically developed countries to aid women and clinicians in decision making. We searched the Google Scholar, CINAHL, and PubMed databases using key terms birth/birthing center or out of hospital with perinatal/neonatal outcomes. Ancestry searches identified additional studies, and an alert was set for new publications. We included primary source studies in English, published after 1980, conducted in a developed country, and researching planned birth in centers with guidelines similar to American Association of Birth Centers standards. After initial review, we conducted a preliminary analysis, assessing which measures of neonatal health, morbidity, and mortality were included across studies. Neonatal mortality was selected as the sole summary measure as other measures were sporadically reported or inconsistently defined. Seventeen studies were included, representing at least 84,500 women admitted to a birth center in labor. There were substantial differences of study design, sampling techniques, and definitions of neonatal outcomes across studies, limiting conclusive statements of the effect of intrapartum care in a birth center. No reviewed study found a statistically increased rate of neonatal mortality in birth centers compared to low-risk women giving birth in hospitals, nor did data suggest a trend toward higher neonatal mortality in birth centers. As in all birth settings, nulliparous women, women aged greater than 35 years, and women with pregnancies of more than 42 weeks' gestation may have an increased risk of neonatal mortality. There are substantial flaws in the literature concerning the effect of birth center care on neonatal outcomes. More research is needed on subgroups at risk of poor outcomes in the birth center environment. To expedite research, consistent use of national and international definitions of perinatal and neonatal mortality within data registries and greater detail on adverse outcomes would be beneficial. © 2018 by the American College of Nurse-Midwives.

The ETATMBA (Enhancing Training And Technology for Mothers and Babies in Africa) project-trained associate clinicians (ACs/clinical officers) as advanced clinical leaders in emergency obstetric and neonatal care. This trial aimed to evaluate the impact of training on obstetric health outcomes in Malawi. A cluster randomised controlled trial with 14 districts of Malawi (8 intervention, 6 control) as units of randomisation. Intervention districts housed the 46 ACs who received the training programme. The primary outcome was district (health facility-based) perinatal mortality rates. Secondary outcomes included maternal mortality ratios, neonatal mortality rate, obstetric and birth variables. The study period was 2011-2013. Mortality rates/ratios were examined using an interrupted time series (ITS) to identify trends over time. The ITS reveals an improving trend in perinatal mortality across both groups, but better in the control group (intervention, effect -3.58, SE 2.65, CI (-9.85 to 2.69), p=0.20; control, effect -17.79, SE 6.83, CI (-33.95 to -1.64), p=0.03). Maternal mortality ratios are seen to have improved in intervention districts while worsening in the control districts (intervention, effect -38.11, SE 50.30, CI (-157.06 to 80.84), p=0.47; control, effect 11.55, SE 87.72, CI (-195.87 to 218.98), p=0.90). There was a 31% drop in neonatal mortality rate in intervention districts while in control districts, the rate rises by 2%. There are no significant differences in the other secondary outcomes. This is one of the first randomised studies looking at the effect of structured training on health outcomes in this setting. Notwithstanding a number of limitations, this study suggests that up-skilling this cadre is possible, and could impact positively on health outcomes. ISRCTN63294155; Results.

Effectiveness of interventions to screen and manage infections during pregnancy on reducing stillbirths: a review

PubMed Central

2011-01-01

Background Infection is a well acknowledged cause of stillbirths and may account for about half of all perinatal deaths today, especially in developing countries. This review presents the impact of interventions targeting various important infections during pregnancy on stillbirth or perinatal mortality. Methods We undertook a systematic review including all relevant literature on interventions dealing with infections during pregnancy for assessment of effects on stillbirths or perinatal mortality. The quality of the evidence was assessed using the adapted Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach by Child Health Epidemiology Reference Group (CHERG). For the outcome of interest, namely stillbirth, we applied the rules developed by CHERG to recommend a final estimate for reduction in stillbirth for input to the Lives Saved Tool (LiST) model. Results A total of 25 studies were included in the review. A random-effects meta-analysis of observational studies of detection and treatment of syphilis during pregnancy showed a significant 80% reduction in stillbirths [Relative risk (RR) = 0.20; 95% confidence interval (CI): 0.12 - 0.34) that is recommended for inclusion in the LiST model. Our meta-analysis showed the malaria prevention interventions i.e. intermittent preventive treatment (IPTp) and insecticide-treated mosquito nets (ITNs) can reduce stillbirths by 22%, however results were not statistically significant (RR = 0.78; 95% CI: 0.59 – 1.03). For human immunodeficiency virus infection, a pooled analysis of 6 radomized controlled trials (RCTs) failed to show a statistically significant reduction in stillbirth with the use of antiretroviral in pregnancy compared to placebo (RR = 0.93; 95% CI: 0.45 – 1.92). Similarly, pooled analysis combining four studies for the treatment of bacterial vaginosis (3 for oral and 1 for vaginal antibiotic) failed to yield a significant impact on perinatal mortality (OR = 0.88; 95% CI: 0.50 – 1.55). Conclusions The clearest evidence of impact in stillbirth reduction was found for adequate prevention and treatment of syphilis infection and possibly malaria. At present, large gaps exist in the growing list of stillbirth risk factors, especially those that are infection related. Potential causes of stillbirths including HIV and TORCH infections need to be investigated further to help establish the role of prevention/treatment and its subsequent impact on stillbirth reduction.

No consensus definition of macrosomia currently exists among researchers and obstetricians. We aimed to identify a definition of macrosomia that is more predictive of maternal and perinatal mortality and morbidity in low- and middle-income countries. We conducted a secondary data analysis using WHO Global Survey on Maternal and Perinatal Health data on Africa and Latin America from 2004 to 2005 and Asia from 2007 to 2008. We compared adverse outcomes, which were assessed by the composite maternal mortality and morbidity index (MMMI) and perinatal mortality and morbidity index (PMMI) in subgroups with birthweight (3000-3499 g [reference group], 3500-3999 g, 4000-4099 g, 4100-4199 g, 4200-4299 g, 4300-4399 g, 4400-4499 g, 4500-4999 g) or country-specific birthweight percentile for gestational age (50(th)-74(th) percentile [reference group], 75(th)-89(th), 90(th)-94(th), 95(th)-96(th), and ≥97(th) percentile). Two-level logistic regression models were used to estimate odds ratios of MMMI and PMMI. A total of 246,659 singleton term births from 363 facilities in 23 low- and middle-income countries were included. Adjusted odds ratios (aORs) for intrapartum caesarean sections exceeded 2.0 when birthweight was greater than 4000 g (2·00 [95% CI: 1·68, 2·39], 2·42 [95% CI: 2·02, 2·89], 2·01 [95% CI: 1·74, 2·33] in Africa, Asia and Latin America, respectively). aORs of MMMI reached 2.0 when birthweight was greater than 4000 g, 4500 g in Asia and Africa, respectively. aORs of PMMI approached to 2.0 (1·78 [95% CI: 1·16, 2·74]) when birthweight was greater than 4500 g in Latin America. When birthweight was at the 90(th) percentile or higher, aORs of MMMI and PMMI increased, but none exceeded 2.0. The population-specific definition of macrosomia using birthweight cut-off points irrespective of gestational age (4500 g in Africa and Latin America, 4000 g in Asia) is more predictive of maternal and perinatal adverse outcomes, and simpler to apply compared to the definition based on birthweight percentile for a given gestational age.

This clinical picture is defined as a delivery that requires additional obstetric maneuvers to release the shoulders after gentle downward traction has failed. Shoulder dystocia occurs when the fetal shoulder impacts on the maternal symphysis or sacral promontory. The incidence of shoulder dystocia is 0.2-0.6%. High perinatal mortality and morbidity is associated with the condition, even when it is managed appropriately. Obstetricians should be aware of the existing risk factors, but should always be alert to the possibility of shoulder dystocia in all labors. Maternal morbidity is also increased, particularly postpartum hemorrhage, rupture of the uterus, injury of the bladder, urethra and the bowels and fourth-degree perineal tears. Complications of the newborn include asphyxia, perinatal mortality, fracture of the clavicula and the humerus. Brachial plexus injuries are one of the most important fetal complications of shoulder dystocia, complicating 4-16% of such deliveries. The purpose of this article is to review the current evidence regarding the possible prediction, prevention and management of shoulder dystocia.

Preterm birth and inflammation-The role of genetic polymorphisms.

Spontaneous preterm labour and preterm births are still the leading cause of perinatal morbidity and mortality in the developed world. Previous efforts to prevent preterm birth have been hampered by a poor understanding of the underlying pathophysiology, inadequate diagnostic tools and generally ineffective therapies. Clinical, epidemiological and experimental studies indicate that genito-urinary tract infections play a critical role in the pathogenesis of preterm birth. Moreover, intrauterine infection increases perinatal mortality and morbidity, such as cerebral palsy and chronic lung disease, significantly. It has recently been suggested that gene-environment interactions play a significant role in determining the risk of preterm birth. Polymorphisms of certain critical genes may be responsible for a harmful inflammatory response in those who possess them. Accordingly, polymorphisms that increase the magnitude or the duration of the inflammatory response were associated with an increased risk of preterm birth. In contrast polymorphisms that decrease the inflammatory response were associated with a lower risk of preterm birth. This article will review the current understanding of pathogenetic pathways in the aetiology of preterm birth.

To see the effect of amnioinfusion on perinatal outcome in cases of meconium staining of liquor. This study was conducted in department of Obstetrics and Gynaecology, unit 1, Jinnah Postgraduate Medical Centre, Karachi, from 1st January 1998 to 31st December 2000. Four hundred patients were included in this study, assigning 200 for amnioinfusion and 200 as control. All patients were matched in both the groups with respect to age, antenatal booking, parity, gestational age, stage of labour, colour of amniotic fluid and fetal birth weight. Both the groups were found to be comparable. The rate of Caesarean section was found to be 37% in amnioinfusion group, which collaborates with other international studies. The fetal outcome was better i.e. 91% alive and healthy, after amnioinfusion due to dilution of meconium stained amniotic fluid with physiological solutions. The perinatal outcome was recorded by Apgar score at 5 minutes. The perinatal morbidity and mortality both were significantly lowered and was found to be 6% as compared to 14% in control, which was also noticed by less number of admissions in nursery i.e. 12% and perinatal deaths. The incidence of meconium aspiration syndrome was found to be 56% in control and was reduced to 22% after amnioinfusion in the other arm of the study. These results are very encouraging and suggestion can be safely made that in future amnioinfusion will be the ideal method of preventing fetal distress due to meconium stained amniotic fluid.

To investigate the association between learning climate and adverse perinatal and maternal outcomes in obstetrics-gynecology departments. The authors analyzed 23,629 births and 103 learning climate evaluations from 16 nontertiary obstetrics-gynecology departments in the Netherlands in 2013. Multilevel logistic regressions were used to calculate the odds of adverse perinatal and maternal outcomes, by learning climate score tertile, adjusting for maternal and department characteristics. Adverse perinatal outcomes included fetal or early neonatal mortality, five-minute Apgar score < 7, or neonatal intensive care unit admission for ≥ 24 hours. Adverse maternal outcomes included postpartum hemorrhage and/or transfusion, death, uterine rupture, or third- or fourth-degree perineal laceration. Bias analyses were conducted to quantify the sensitivity of the results to uncontrolled confounding and selection bias. Learning climate scores were significantly associated with increased odds of adverse perinatal outcomes (aOR 2.06, 95% CI 1.14-3.72). Compared with the lowest tertile, departments in the middle tertile had 46% greater odds of adverse perinatal outcomes (aOR 1.46, 95% CI 1.09-1.94); departments in the highest tertile had 69% greater odds (aOR 1.69, 95% CI 1.24-2.30). Learning climate was not associated with adverse maternal outcomes (middle vs. lowest tertile: OR 1.04, 95% CI 0.93-1.16; highest vs. lowest tertile: OR 0.98, 95% CI 0.88-1.10). Learning climate was associated with significantly increased odds of adverse perinatal, but not maternal, outcomes. Research in similar clinical contexts is needed to replicate these findings and explore potential mechanisms behind these associations.

The aim of the present investigation was to study the influence of O2-ventilation, blind buffer therapy with Na-bicarbonate, late cord clamping and infusion of low molculare weight dextran on morbidity of Respiratory-Distress-Syndrom (RDS) and mortality during the first week in infants with a birthweight of 2500 g and less. The charts of 536 infants were studied. There were 481 life birth and 55 stillbirth (10.2%). In 185 infants the pH and Base-excess in the umbilical arterial blood was meassured. The infants born in 1969--1971 were compaired with them born in 1972--1973. In 52% of the "premature infants" the pH was 7.25 U and lower and in 90% of the Base-Excess was --4.5 meq/l and more. The perinatal mortality (PM) was 30% and 13% (P less than 0.01) resp. There was a correlation to the birthweight. The decrease of the PM was related to the fall in mortality of infant during the first week: 21% and 4% resp. Here too, there was a correlation to birthweight and gestational age. The morbidity in RDS: 20.6% and 10.0% (P less than 0.01) and mortality following RDS: 79.3% and 35.0% resp. (P less than 0.01) was also low in 1972--1973. The results permit us to conclude that it is of great importance to correct fetal acidosis immediately after birth to prevent irreversible alterations in the lung. It could also be of value to encrease cardiac output and lungperfusion by late cord clamping and injection of dextran 40. The other procedures belong to standard managment in handling an asphyxiated fetus.

Amnioinfusion for meconium-stained liquor in labour.

Amnioinfusion aims to prevent or relieve umbilical cord compression during labour by infusing a solution into the uterine cavity. It is also thought to dilute meconium when present in the amniotic fluid and so reduce the risk of meconium aspiration. However it may be that the mechanism of effect is that it corrects oligohydramnios (reduced amniotic fluid), for which thick meconium staining is a marker. The objective of this review was to assess the effects of amnioinfusion for meconium-stained liquor on perinatal outcome. The Cochrane Pregnancy and Childbirth Group trials register and the Cochrane Controlled Trials Register were searched. Randomised trials comparing amnioinfusion with no amnioinfusion for women in labour with moderate or thick meconium-staining of the amniotic fluid. Eligibility and trial quality were assessed by one reviewer. Ten studies, most involving small numbers of participants, were included. Under standard perinatal surveillance, amnioinfusion was associated with a reduction in the following: heavy meconium staining of the liquor (relative risk 0.03, 95% confidence interval 0.01 to 0.15); variable fetal heart rate deceleration (relative risk 0.47, 95% confidence interval 0.24 to 0. 90); and a trend to reduced caesarean section overall (relative risk 0.83, 95% confidence interval 0.69 to 1.00). No perinatal deaths were reported. Under limited perinatal surveillance, amnioinfusion was associated with a reduction in the following: meconium aspiration syndrome (relative risk 0.24, 95% confidence interval 0. 12 to 0.48); neonatal hypoxic ischaemic encephalopathy (relative risk 0.07, 95% confidence interval 0.01 to 0.56) and neonatal ventilation or intensive care unit admission (relative risk 0.56, 95% confidence interval 0.39 to 0.79); there was a trend towards reduced perinatal mortality (relative risk 0.34, 95% confidence interval 0.11 to 1.06). Amnioinfusion is associated with improvements in perinatal outcome, particularly in settings where facilities for perinatal surveillance are limited. The trials reviewed are too small to address the possibility of rare but serious maternal adverse effects of amnioinfusion.

Pre-gestational diabetes mellitus is associated with increased risk for maternal and fetal adverse outcomes. This systematic review was carried out to evaluate the effectiveness and safety of pre-pregnancy care in improving the rate of congenital malformations and perinatal mortality for women with pre-gestational diabetes mellitus. We searched the following databases, MEDLINE, EMBASE, WEB OF SCIENCE, Cochrane Library, including the CENTRAL register of controlled trials and CINHAL up to December 2011, without language restriction, for any pre-pregnancy care aiming at health promotion, glycemic control and screening and treatment of diabetes complications in women with type I or type II diabetes mellitus. Study design were trials (randomized and non-randomized), cohort and case-control studies. Of the 2452 title scanned 54 full papers were retrieved of those 21 studies were included in this review. Twelve cohort studies at low and medium risk of bias, with 3088 women, were included in the meta-analysis. Meta-analysis suggested that pre-pregnancy care is effective in reducing congenital malformation, Risk Ratio (RR) 0.25 (95% CI 0.16-0.37), number needed to treat (NNT) 19 (95% CI 14-24), and perinatal mortality RR 0.34 (95% CI 0.15-0.75), NNT = 46 (95% CI 28-115). Pre-pregnancy care lowers glycosylated hemoglobin A1c (HbA1c) in the first trimester of pregnancy by an average of 1.92% (95% CI -2.05 to -1.79). However women who received pre-pregnancy care were at increased risk of hypoglycemia during the first trimester of pregnancy RR 1.51 (95% CI 1.15-1.99). Pre-pregnancy care for women with pre-gestational type 1 or type 2 diabetes mellitus is effective in improving rates of congenital malformations, perinatal mortality and in reducing maternal HbA1C in the first trimester of pregnancy. Pre-pregnancy care might cause maternal hypoglycemia in the first trimester of pregnancy.

A prospective study aiming at assessing the effect of adding a third dose sulphadoxine-pyrimethamine (SP) to the standard two-dose intermittent preventive treatment for pregnant women was carried out in Hounde, Burkina Faso, between March 2006 and July 2008. Pregnant women were identified as earlier as possible during pregnancy through a network of home visitors, referred to the health facilities for inclusion and followed up until delivery. Study participants were enrolled at antenatal care (ANC) visits and randomized to receive either two or three doses of SP at the appropriate time. Women were visited daily and a blood slide was collected when there was fever (body temperature > 37.5°C) or history of fever. Women were encouraged to attend ANC and deliver in the health centre, where the new-born was examined and weighed. The timing and frequency of malaria infection was analysed in relation to the risk of low birth weight, maternal anaemia and perinatal mortality. Data on birth weight and haemoglobin were available for 1,034 women. The incidence of malaria infections was significantly lower in women having received three instead of two doses of SP. Occurrence of first malaria infection during the first or second trimester was associated with a higher risk of low birth weight: incidence rate ratios of 3.56 (p < 0.001) and 1.72 (p = 0.034), respectively. After adjusting for possible confounding factors, the risk remained significantly higher for the infection in the first trimester of pregnancy (adjusted incidence rate ratio = 2.07, p = 0.002). The risk of maternal anaemia and perinatal mortality was not associated with the timing of first malaria infection. Malaria infection during first trimester of pregnancy is associated to a higher risk of low birth weight. Women should be encouraged to use long-lasting insecticidal nets before and throughout their pregnancy.

To compare the perinatal outcomes of singleton pregnancies resulting from blastocyst- vs cleavage-stage embryo transfer and to assess whether they differ between fresh and frozen embryo transfer cycles. A systematic review of the literature was carried out using the Scopus, MEDLINE and ISI Web of Science databases with no time restriction. We included only peer-reviewed articles involving humans, in which perinatal outcomes of singleton pregnancies after blastocyst-stage embryo transfer were compared with those after cleavage-stage embryo transfer. Primary outcomes were preterm birth before 37 weeks and low birth weight (< 2500 g). Secondary outcomes were very preterm birth before 32 weeks, very low birth weight (< 1500 g), small-for-gestational-age (SGA), large-for-gestational-age (LGA), perinatal mortality and congenital anomaly. A meta-analysis was performed using a random-effects model. Three subgroups were evaluated: fresh only, frozen only and fresh plus frozen embryo transfer cycles. From a total of 3928 articles identified, 14 were selected for qualitative/quantitative analysis. Significantly higher incidences of preterm birth < 37 weeks (11 studies, n = 106 629 participants; risk ratio (RR), 1.15 (95% CI, 1.05 - 1.25); P = 0.002) and very preterm birth < 32 weeks (seven studies, n = 103 742; RR, 1.16 (95% CI, 1.02-1.31); P = 0.03) were observed after blastocyst- than after cleavage-stage embryo transfer in fresh cycles. However, the risk of preterm and very preterm birth was similar after blastocyst- and cleavage-stage transfers in frozen and fresh plus frozen cycles. Overall effect size analysis revealed fewer SGA deliveries after blastocyst- compared with cleavage-stage transfer in fresh cycles but a similar number in frozen cycles. Conversely, more LGA deliveries were observed after blastocyst- compared with cleavage-stage transfer in frozen cycles (two studies, n = 39 044; RR, 1.18 (95% CI, 1.09-1.27); P < 0.0001) and no differences between the two groups in fresh cycles (four studies, n = 42 982; RR, 1.14 (95% CI, 0.97-1.35); P = 0.11). There were no differences with respect to low birth weight, very low birth weight or congenital anomalies between blastocyst- and cleavage-stage transfers irrespective of the cryopreservation method employed. Only one study reported a higher incidence of perinatal mortality after blastocyst- vs cleavage-stage embryo transfer in frozen cycles, while no differences were found in fresh cycles. Our results suggest that cryopreservation of embryos can influence outcome of pregnancy conceived following blastocyst- vs cleavage-stage embryo transfer in terms of preterm birth, very preterm birth, LGA, SGA and perinatal mortality. Caution should be exercised in interpreting these findings given the low level of evidence and wide heterogeneity of the studies. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

Bhat, Amritha; Mao, Johnny; Unützer, Jürgen; Reed, Susan; Unger, Jennifer

Mental health care integrated into obstetric settings improves access to perinatal depression treatments. Digital interactions such as text messaging between patient and provider can further improve access. We describe the use of text messaging within a perinatal Collaborative Care (CC) program, and explore the association of text messaging content with perinatal depression outcomes. We analyzed data from an open treatment trial of perinatal CC in a rural obstetric clinic. Twenty five women with Patient Health Questionnaire-9 score of ≥10 enrolled in CC, and used text messaging to communicate with their Care Manager(CM). We used surveys and focus groups to assessacceptability of text messaging with surveys and focus groups. We calculated the number of text messages exchanged, and analyzed content to understand usage patterns. We explored association between text messaging content and depression outcomes. CMs initiated 85.4% messages, and patients responded to 86.9% messages. CMs used text messaging for appointment reminders, and patients used it to obtain obstetric and parenting information. CMs had concerns about the likelihood of boundary violations. Patients appreciated the asynchronous nature of text messaging. Text messaging is feasible and acceptable within a perinatal CC program. We need further research into the effectiveness of text messaging content, and response protocols. Copyright © 2018 Elsevier Inc. All rights reserved.

Bone up: craniomandibular development and hard-tissue biomineralization in neonate mice.

The presence of regional variation in the osteogenic abilities of cranial bones underscores the fact that the mechanobiology of the mammalian skull is more complex than previously recognized. However, the relationship between patterns of cranial bone formation and biomineralization remains incompletely understood. In four strains of mice, micro-computed tomography was used to measure tissue mineral density during perinatal development in three skull regions (calvarium, basicranium, mandible) noted for variation in loading environment, embryological origin, and ossification mode. Biomineralization levels increased during perinatal ontogeny in the mandible and calvarium, but did not increase in the basicranium. Tissue mineral density levels also varied intracranially, with density in the mandible being highest, in the basicranium intermediate, and in the calvarium lowest. Perinatal increases in, and elevated levels of, mandibular biomineralization appear related to the impending postweaning need to resist elevated masticatory stresses. Similarly, perinatal increases in calvarial biomineralization may be linked to ongoing brain expansion, which is known to stimulate sutural bone formation in this region. The lack of perinatal increase in basicranial biomineralization could be a result of earlier developmental maturity in the cranial base relative to other skull regions due to its role in supporting the brain's mass throughout ontogeny. These results suggest that biomineralization levels and age-related trajectories throughout the skull are influenced by the functional environment and ontogenetic processes affecting each region, e.g., onset of masticatory loads in the mandible, whereas variation in embryology and ossification mode may only have secondary effects on patterns of biomineralization. Knowledge of perinatal variation in tissue mineral density, and of normal cranial bone formation early in development, may benefit clinical therapies aiming to correct developmental defects and traumatic injuries in the skull, and more generally characterize loading environments and skeletal adaptations in mammals by highlighting the need for multi-level analyses for evaluating functional performance of cranial bone.

2016-10-01

Immediate neonatal outcome in pregnancies complicated by placenta previa is largely dependent on gestational age. We aimed to investigate whether placenta previa increases the risk for perinatal mortality and immediate morbidity of the offspring born at term. A population-based cohort study included all singleton pregnancies, with and without placenta previa, delivered at term. Maternal and pregnancy characteristics as well as immediate neonatal morbidity and mortality were compared. Deliveries occurred between the years 1991-2013 in a tertiary medical center. Multiple pregnancies, and fetal congenital malformations were excluded. During the study period 233,123 consecutive term deliveries met the inclusion criteria; 0.2 % of the babies were born to mothers diagnosed with placenta previa. Women with placenta previa were significantly older and more likely to have had a previous cesarean section. Pregnancies were more likely to be complicated with pathological presentations and cesarean hysterectomies. Babies born at term following pregnancies with placenta previa were more likely to weigh less than 2500 g (OR 2.78 CI 1.9-3.9, p < 0.001). However, 5 min Apgar score and perinatal mortality rates were comparable between the groups. Neonatal outcomes remained comparable between the groups in a sub-analysis of cesarean deliveries only. Although placenta previa pregnancies involve higher maternal morbidity rates, term offsprings are not at an increased risk for immediate adverse outcome.

Objective Identifying infant deaths with common underlying causes and potential intervention points is critical to infant mortality surveillance and the development of prevention strategies. We constructed an International Classification of Diseases 10th Revision (ICD-10) parallel to the Dollfus cause-of-death classification scheme first published in 1990, which organized infant deaths by etiology and their amenability to prevention efforts. Methods Infant death records for 1996, dual-coded to the ICD Ninth Revision (ICD-9) and ICD-10, were obtained from the CDC public-use multiple-cause-of-death file on comparability between ICD-9 and ICD-10. We used the underlying cause of death to group 27,821 infant deaths into the nine categories of the ICD-9-based update to Dollfus' original coding scheme, published by Sowards in 1999. Comparability ratios were computed to measure concordance between ICD versions. Results The Dollfus classification system updated with ICD-10 codes had limited agreement with the 1999 modified classification system. Although prematurity, congenital malformations, Sudden Infant Death Syndrome, and obstetric conditions were the first through fourth most common causes of infant death under both systems, most comparability ratios were significantly different from one system to the other. Conclusion The Dollfus classification system can be adapted for use with ICD-10 codes to create a comprehensive, etiology-based profile of infant deaths. The potential benefits of using Dollfus logic to guide perinatal mortality reduction strategies, particularly to maternal and child health programs and other initiatives focused on improving infant health, warrant further examination of this method's use in perinatal mortality surveillance.

Reduction of maternal and perinatal mortality in rural and peri-urban settings: what works?

PubMed

Kwast, B E

1996-10-01

The purpose of this article is two-fold: (i) to lay out conceptual frameworks for programming in the fields of maternal and neonatal health for the reduction of maternal and peri/neonatal mortality; (ii) to describe selected MotherCare demonstration projects in the first 5 years between 1989 and 1993 in Bolivia, Guatemala, Indonesia and Nigeria. In Inquisivi, Bolivia, Save the Children/Bolivia, worked with 50 women's groups in remote rural villages in the Andean mountains. Through a participatory research process, the 'autodiagnosis', actions identified by women's groups included among others: provision of family planning through a local non-governmental organization (NGO), training of community birth attendants, income generating projects. In Quetzaltenango, Guatemala, access was improved through training of traditional birth attendants (TBAs) in timely recognition and referral of pregnancy/delivery/neonatal complications, while quality of care in health facilities was improved through modifying health professionals' attitude towards TBAs and clients, and implementation of management protocols. In Indonesia, the University of Padjadjaran addressed issues of referral and emergency obstetric care in the West-Java subdistrict of Tanjunsari. Birthing homes with radios were established in ten of the 27 villages in the district, where trained nurse/midwives provided maternity care on a regular basis. In Nigeria professional midwives were trained in interpersonal communication and lifesaving obstetric skills, while referral hospitals were refurbished and equipped. While reduction in maternal mortality after such a short implementation period is difficult to demonstrate, all projects showed improvements in referral and in reduction in perinatal mortality.

Accentuated lines in the enamel of primary incisors from skeletal remains: A contribution to the explanation of early childhood mortality in a medieval population from Poland.

Physiological disruptions resulting from an impoverished environment during the first years of life are of key importance for the health and biological status of individuals and populations. Studies of growth processes in archaeological populations point to the fact that the main causes of childhood mortality in the past are to be sought among extrinsic factors. Based on this assumption, one would expect random mortality of children, with the deceased individuals representing the entire subadult population. The purpose of this study is to explore whether differences in early childhood survival are reflected in differences in deciduous tooth enamel, which can provide an insight into the development of an individual during prenatal and perinatal ontogeny. Deciduous incisors were taken from 83 individuals aged 2.0-6.5 years from a medieval inhumation cemetery dated AD 1300-1600. Prenatal and postnatal enamel formation time, neonatal line width, and the number of accentuated lines were measured using an optical microscope. The significantly wider neonatal line and the higher frequency of accentuated lines in the enamel of the incisors of children who died at the age of 2-3 years suggest the occurrence of stronger or more frequent stress events in this group. These results indicate that in skeletal populations mortality was not exclusively determined by random external factors. Individuals predisposed by an unfavorable course of prenatal and perinatal growth were more likely to die in early childhood. © 2015 Wiley Periodicals, Inc.

Comparing two survey methods for estimating maternal and perinatal mortality in rural Cambodia.

We need solid estimates of maternal mortality rates (MMR) to monitor the impact of maternal care programs. Cambodian health authorities and WHO report the MMR in Cambodia at 450 per 100,000 live births. The figure is drawn from surveys where information is obtained by interviewing respondents about the survival of all their adult sisters (sisterhood method). The estimate is statistically imprecise, 95% confidence intervals ranging from 260 to 620/100,000. The MMR estimate is also uncertain due to under-reporting; where 80-90% of women deliver at home maternal fatalities may go undetected especially where mortality is highest, in remote rural areas. The aim of this study was to attain more reliable MMR estimates by using survey methods other than the sisterhood method prior to an intervention targeting obstetric rural emergencies. The study was carried out in rural Northwestern Cambodia where access to health services is poor and poverty, endemic diseases, and land mines are endemic. Two survey methods were applied in two separate sectors: a community-based survey gathering data from public sources and a household survey gathering data direct from primary sources. There was no statistically significant difference between the two survey results for maternal deaths, both types of survey reported mortality rates around the public figure. The household survey reported a significantly higher perinatal mortality rate as compared to the community-based survey, 8.6% versus 5.0%. Also the household survey gave qualitative data important for a better understanding of the many problems faced by mothers giving birth in the remote villages. There are detection failures in both surveys; the failure rate may be as high as 30-40%. PRINCIPLE CONCLUSION: Both survey methods are inaccurate, therefore inappropriate for evaluation of short-term changes of mortality rates. Surveys based on primary informants yield qualitative information about mothers' hardships important for the design of future maternal care interventions.

Acute viral hepatitis is the most common cause of jaundice in pregnancy. Amongst hepatitis E bears a deadly combination with pregnancy, leading to loss of very young lives. There is almost no data available in this aspect documenting prevalence, profile and effect of jaundice on outcome of pregnancy in Bangladesh. This observational study was done to determine and analyze the frequency, cause and outcome of jaundice in pregnancy among the admitted patients in the feto-maternal medicine wing of Bangabandhu Sheikh Mujib Medical University, for a 2 years period from August 2009 to July 2011. Management was done in collaboration with the hepatologists, hematologists and intensive care unit specialist. Outcome was noted in terms of the mode of delivery, maternal complications, need of blood transfusion and fresh frozen plasma and maternal end result. Fetal outcome was assessed by birth weight, Apgar score, neonatal admission, and perinatal mortality. Prevalence of jaundice was found 2.5% among all high risk and 1.3% among all obstetric admissions. Hepatitis E was the commonest cause and responsible for 80.4% cases of jaundice and next was cholestatic jaundice. Almost half of the patients (43.4%) faced complications like post partum haemorrhage (15.3%), hepatic encephalopathy (10.8%), ante partum hemorrhage (6.5%). Preterm delivery was noted in 71.1% cases. Out of 46 patients with jaundice four (4) mothers died due to hepatic encephalopathy in hepatitis E group. Regarding perinatal outcome 55.8% were of low birth weight, 35.3% had low Apgar score and perinatal mortality was 6.4%.

The primary objective is to determine whether intrauterine vesicoamniotic shunting for fetal bladder outflow obstruction, compared with conservative, noninterventional care, improves prenatal and perinatal mortality and renal function. The secondary objectives are to determine if shunting for fetal bladder outflow obstruction improves perinatal morbidity, to determine if improvement in outcomes is related to prognostic assessment at diagnosis and, if possible, derive a prognostic risk index and to determine the safety and long-term efficacy of shunting. A multicentre randomised controlled trial (RCT). Fetal medicine units. Pregnant women with singleton, male fetus with isolated lower urinary tract obstruction (LUTO). Following ultrasound diagnosis of LUTO in a male fetus and exclusion of other structural and chromosomal anomalies, participation in the trial will be discussed with the mother and written information given. Consent for participation in the trial will be taken and the mother randomised via the internet to either insertion of a vesicoamniotic shunt or expectant management. During pregnancy, both groups will be followed with regular ultrasound scans looking at viability, renal measurements and amniotic fluid volume. Following delivery, babies will be followed up by paediatric nephrologists/urologists at 4-6 weeks, 12 months and 3 and 5 years to assess renal function via serum creatinine, renal ultrasound and need for dialysis/transplant. The main outcome measures will be perinatal mortality rates and renal function at 4-6 weeks and 12 months measured via serum creatinine, renal ultrasound and need for dialysis/transplant.

Background: Obstetricians, gynecologists, and midwives are the most common specialists of the medical sciences group against whom medical malpractices are claimed, many of which are avoidable and preventable. Therefore, the present study was conducted to investigate the causes of claims regarding medical malpractices resulting in maternal and perinatal mortality. Materials and Methods: A descriptive cross-sectional study was conducted and 7616 claims of medical malpractices in the field of obstetrics, gynecology, and midwifery that were referred from all 31 provinces to the central commission of legal medicine were studied during 2011–2012. Therefore, the present research is a national inclusive study covering all the provinces across Iran. To collect information from the transcript of medical malpractices cases, a researcher-made checklist was used, and the collected data were analyzed. Results: The results of the present study showed that among all the medical malpractice claims regarding pregnancy and childbirth (42.24%), the majority concerned perinatal death (71.82%) and maternal death (28.16%). Conclusions: Medical malpractice complaints are increasing; although, most of these claims are preventable. To achieve this aim, it is necessary for obstetricians, gynecologists, and midwives to try to reduce the complaints by paying more attention to the signs and symptoms of diseases, performing all the diagnostic and therapeutic measures according to the scientific criteria, and fully document patients' records. In addition, patients' acquaintance with the importance of measurements and examinations, before and during pregnancy care and even after childbirth is crucial. PMID:28904542

Why is continuum of care from home to health facilities essential to improve perinatal survival?

PubMed

Bahl, Rajiv; Qazi, Shamim; Darmstadt, Gary L; Martines, Jose

2010-12-01

The period around the time of delivery is extremely hazardous for infants in developing countries. After the first week the risk drops sharply, and survival improves markedly. To reduce perinatal mortality, a continuum of care between the home and the various facilities is essential during pregnancy, childbirth and the newborn period. This paper reviews strategies to promote the establishment of this continuum: providing health care within or close to home by frontline workers and increasing the use of services in health facilities through community mobilization and financing strategies. As perinatal care and care for seriously sick children face common challenges and lessons could be learned from successful strategies for management of other illnesses, this paper also reviews intervention models involving community health workers (CHWs) to improve case management of sick children at the household and community levels. Available evidence suggests that the community strategy with the greatest impact on neonatal mortality is home visits by CHWs combined with community mobilization. The same strategy appears to be effective in increasing health facility utilization. An equally effective strategy for increasing health facility utilization seems to be financing health care to remove financial access barriers, particularly using conditional cash transfers or vouchers. Although the availability of information on the effect of community interventions to improve newborn health has increased in the recent past, significant gaps remain. Information on the effectiveness of strategies in different settings, particularly in sub-Saharan Africa, cost-effectiveness and sustainability are particularly needed and should be gathered in future studies.

To explore the attitudes, strategies and habits of Somalian immigrant women related to pregnancy and childbirth, in order to gain an understanding as to how cultural factors might affect perinatal outcome. Interpreter assisted qualitative in depth interviews around topics such as attitudes and strategies regarding childbirth. Fifteen women from the Somalian community in a city in Sweden, between the ages of 20 and 55 years with delivery experience in Somalia and Sweden. The interviews describe how the women themselves perceived their experiences of childbirth in the migrant situation. Many voluntarily decreased food intake in order to have a smaller fetus, an easier delivery and to avoid caesarean section. The participants considered a safe delivery to be the same as a normal vaginal delivery They reduced food intake in order to diminish the growth of the fetus, thereby avoiding caesarean section and mortality. The practice of food intake reduction, while rational for the participants when in Somalia, was found less rational in Sweden and may lead to suboptimal obstetric surveillance. Somalian women have childbirth strategies that differ from those of Swedish women. These strategies should be seen as 'survival behaviours' related to their background in an environment with high maternal mortality. The hypothesis generated is that there is a relationship between the strategies during pregnancy and adverse perinatal outcome among Somalian immigrants. Considering the strong association of the habits to safe birth, it seems doubtful whether the women will change their habits as long as health care providers are unaware of their motives. We suggest a more culturally sensitive perinatal surveillance.

Approximately one-third of a million women die each year from pregnancy-related conditions. Three-quarters of these deaths are considered avoidable. Millennium Development Goal five calls for a reduction in maternal mortality and the establishment of universal access to high quality reproductive health care. There is evidence of a relationship between lower levels of maternal education and higher maternal mortality. This study examines the relationship between maternal education and maternal mortality among women giving birth in health care institutions and investigates the association of maternal age, marital status, parity, institutional capacity and state-level investment in health care with these relationships. Cross-sectional information was collected on 287,035 inpatients giving birth in 373 health care institutions in 24 countries in Africa, Asia and Latin America, between 2004-2005 (in Africa and Latin America) and 2007-2008 (in Asia) as part of the WHO Global Survey on Maternal and Perinatal Health. Analyses investigated associations between indicators measured at the individual, institutional and country level and maternal mortality during the intrapartum period: from admission to, until discharge from, the institution where women gave birth. There were 363 maternal deaths. In the adjusted models, women with no education had 2.7 times and those with between one and six years of education had twice the risk of maternal mortality of women with more than 12 years of education. Institutional capacity was not associated with maternal mortality in the adjusted model. Those not married or cohabiting had almost twice the risk of death of those who were. There was a significantly higher risk of death among those aged over 35 (compared with those aged between 20 and 25 years), those with higher numbers of previous births and lower levels of state investment in health care. There were also additional effects relating to country of residence which were not explained in the model. Lower levels of maternal education were associated with higher maternal mortality even amongst women able to access facilities providing intrapartum care. More attention should be given to the wider social determinants of health when devising strategies to reduce maternal mortality and to achieve the increasingly elusive MDG for maternal mortality.

Overwhelming evidence reveals the close link between unwarranted weight gain among childbearing women and childhood adiposity. Yet current barriers limit the capacity of perinatal health care providers (PHCPs) to offer healthy lifestyle counselling. In response, today's Internet savvy women are turning to online resources to access health information, with the potential of revolutionising health services by enabling PHCPs to guide women to appropriate online resources. This paper presents the findings of a project designed to develop an online resource to promote healthy lifestyles during the perinatal period. The methodology involved focus groups and interviews with perinatal women and PHCPs to determine what online information was needed, in what form, and how best it should be presented. The outcome was the development of the Healthy You, Healthy Baby website and smartphone app. This clinically-endorsed, interactive online resource provides perinatal women with a personalised tool to track their weight, diet, physical activity, emotional wellbeing, and sleep patterns based on the developmental stage of their child with links to quality-assured information. One year since the launch of the online resource, data indicates it provides a low-cost intervention delivered across most geographic and socioeconomic strata without additional demands on health service staff.

The impact of perinatal stress on the functional maturation of prefronto-cortical synaptic circuits: implications for the pathophysiology of ADHD?

PubMed

Bock, Jörg; Braun, Katharina

2011-01-01

Enriched as well as impoverished or adverse perinatal environment plays an essential role in the development and refinement of neuronal pathways, which are the neural substrate of intellectual capacity and socioemotional competence. Perinatal experience and learning events continuously interact with the adaptive shaping of excitatory, inhibitory, and neuromodulatory synaptic as well as the endocrine stress systems, including the neuronal corticotropin-releasing factor (CRF) pathways. Adverse environments, such as stress and emotional deprivation can not only delay experience-dependent maturation of these pathways, but also induce permanent changes in prefronto-cortical wiring patterns. We assume that such dysfunctional connections are the neuronal basis for the development of psychosocially induced mental disorders during later life. The aim of this review is to focus on the impact of perinatal stress on the neuronal and synaptic reorganization during brain development and possible implications for the etiology and therapy of mental disorders such as ADHD.

Plasticity of language function after brain damage can depend on maturation of the brain. Children with left-hemisphere perinatal (n = 7) or childhood stroke (n = 5) and 12 controls were investigated using functional magnetic resonance imaging. The verb generation and the sentence comprehension tasks were employed to activate the expressive and receptive language areas, respectively. Weighted laterality indices were calculated and correlated with results assessed by neuropsychological test battery. Compared to controls, children with childhood stroke showed significantly lower mean scores for the expressive (P < .05) and receptive (P = .05) language tests. On functional magnetic resonance imaging they showed left-side cortical activation, as did controls. Perinatal stroke patients showed atypical right-side or bilateral language lateralization during both tasks. Negative correlation for stroke patients was found between scores for expressive language tests and laterality index during the verb generation task. (Re)organization of language function differs in children with perinatal and childhood stroke and correlates with neurocognitive performance. PMID:23748202

The purpose of this study was to evaluate fetal magnetic resonance imaging (MRI) as a modality for predicting perinatal outcomes and lung-related morbidity in fetuses with congenital lung masses (CLM). The records of all patients treated for CLM from 2002 to 2012 were reviewed retrospectively. Fetal MRI-derived lung mass volume ratio (LMVR), observed/expected normal fetal lung volume (O/E-NFLV), and lesion-to-lung volume ratio (LLV) were calculated. Multivariate regression and receiver operating characteristic analyses were applied to determine the predictive accuracy of prenatal imaging. Of 128 fetuses with CLM, 93% (n=118) survived. MRI data were available for 113 fetuses. In early gestation (<26weeks), MRI measurements of LMVR and LLV correlated with risk of fetal hydrops, mortality, and/or need for fetal intervention. In later gestation (>26weeks), LMVR, LLV, and O/E-NFLV correlated with neonatal respiratory distress, intubation, NICU admission and need for neonatal surgery. On multivariate regression, LMVR was the strongest predictor for development of fetal hydrops (OR: 6.97, 1.58-30.84; p=0.01) and neonatal respiratory distress (OR: 12.38, 3.52-43.61; p≤0.001). An LMVR >2.0 predicted worse perinatal outcome with 83% sensitivity and 99% specificity (AUC=0.94; p<0.001). Fetal MRI volumetric measurements of lung masses and residual normal lung are predictive of perinatal outcomes in fetuses with CLM. These data may assist in perinatal risk stratification, counseling, and resource utilization. Copyright © 2014 Elsevier Inc. All rights reserved.

High infant mortality rates among American Indians are disproportionate to state statistics for other races and higher than the national average. These findings prompted a community health center in a large Midwestern city to create and provide an American Indian infant mortality reduction project in the early 1990s. Strategies for program implementation included networking with local organizations, communicating with reservation health clinics throughout the state, educating American Indian mothers and their community about factors contributing to American Indian infant mortality, and providing individual case management to American Indian women and infants. We offer this article for three reasons: This grant project was successful, disparity in rates of infant mortality among peoples of color continues, and a paucity of information exists about the health behaviors of American Indian women.

The insatisfactory completeness of the variables in the Death Certificate (DC) makes it difficult to obtain specific perinatal mortality indicators. To assess the social representation of physicians about the perinatal DC. Twenty-five physicians were interviewed in 15 hospitals in the city of São Paulo, in 2009. Qualitative analysis was performed with the Collective Subject Discourse technique. The DC is primarily considered according to its legal aspect. Physicians feel responsible for fulfilling the cause of death. The majority of them reported receiving help from other professionals to complete information on maternal characteristics and identification variables. There is lack of information on the mother's pre-natal conditions, which can make it difficult to identify the perinatal cause of death, mainly in the Unified Health System (SUS) hospitals. Some participants received specific DC training only when attending medical schools. The organization of medical work may affect the completion of the DC, especially in hospitals from SUS. Other professionals contributed to this task and their training can improve the quality of information.

Background: Wildfire activity is predicted to increase in many parts of the world due to changes in temperature and precipitation patterns from global climate change. Wildfire smoke contains numerous hazardous air pollutants and many studies have documented population health effects from this exposure. Objectives: We aimed to assess the evidence of health effects from exposure to wildfire smoke and to identify susceptible populations. Methods: We reviewed the scientific literature for studies of wildfire smoke exposure on mortality and on respiratory, cardiovascular, mental, and perinatal health. Within those reviewed papers deemed to have minimal risk of bias, we assessed the coherence and consistency of findings. Discussion: Consistent evidence documents associations between wildfire smoke exposure and general respiratory health effects, specifically exacerbations of asthma and chronic obstructive pulmonary disease. Growing evidence suggests associations with increased risk of respiratory infections and all-cause mortality. Evidence for cardiovascular effects is mixed, but a few recent studies have reported associations for specific cardiovascular end points. Insufficient research exists to identify specific population subgroups that are more susceptible to wildfire smoke exposure. Conclusions: Consistent evidence from a large number of studies indicates that wildfire smoke exposure is associated with respiratory morbidity with growing evidence supporting an association with all-cause mortality. More research is needed to clarify which causes of mortality may be associated with wildfire smoke, whether cardiovascular outcomes are associated with wildfire smoke, and if certain populations are more susceptible.

Human beings are constantly exposed to many kinds of environmental agents which affect their health and lifespan. Galactic cosmic rays (GCRs) are the main source of ionizing radiation in the lower troposphere, in which secondary products can penetrate the ground and underground layers. GCRs affect the physical-chemical properties of the terrestrial atmosphere, as well as the biosphere. GCRs are modulated by solar activity and latitudinal geomagnetic field distribution. In our ecological/populational retrospective study, we analyzed the correlation between the annual flux of local secondary GCR-induced ionization (CRII) and mortality rates in the city of Sao Paulo, Brazil, between 1951-2012. The multivariate linear regression analyses adjusted by demographic and weather parameters showed that CRII are significantly correlated with total mortality, infectious disease mortality, maternal mortality, and perinatal mortality rates (p < 0.001). The underlying mechanisms are still unclear. Further cross-sectional and experimental cohort studies are necessary to understand the biophysical mechanisms of the association found here.

Mortality in infants discharged from neonatal intensive care units in Georgia.

Allen, D M; Buehler, J W; Samuels, B N; Brann, A W

Although neonatal intensive care units (NICUs) have contributed to advances in neonatal survival, little is known about the epidemiology of deaths that occur after NICU discharge. To determine mortality rates following NICU discharge, we used linked birth, death, and NICU records for infants born to Georgia residents from 1980 through 1982 and who were admitted to NICUs participating in the state's perinatal care network. Infants who died after discharge (n = 120) had a median duration of NICU hospitalization of 20 days (range, 1 to 148 days) and a median birth weight of 1983 g (range, 793 to 5159 g). The postdischarge mortality rate was 22.7 per 1000 NICU discharges. This rate is more than five times the overall postneonatal mortality rate for Georgia from 1980 to 1982. The most common causes of death were congenital heart disease (23%), sudden infant death syndrome (21%), and infection (13%). Demographic characteristics commonly associated with infant mortality were not strongly associated with the mortality following NICU discharge.

Preterm premature rupture of membranes (PPROM) is a challenging complication of pregnancies and an important cause of perinatal morbidity and mortality. Management of morbidities associated with PPROM is fraught with controversy. However, women should be informed of these complications. This article aimed to review the morbidities, concordance, and predictors of PPROM over a 10-year period. This was a retrospective review of morbidities, concordance, and predictors of PPROM among pregnant women at the University of Nigeria Teaching Hospital, Enugu, Nigeria between January 1, 1999, and December 31, 2008. The morbidities, concordance, and predictors of PPROM were expressed by regression analysis output for PPROM. Primigravidae had the highest occurrence of PPROM. Increasing parity does not significantly influence the incidence of PPROM. The concordance and predictors of PPROM are maternal age (P < 0.000), gestational age at PROM (P < 0.000), latency period (P < 0.000), and birth weight (P < 0.001). PPROM is a major complication of pregnancies and an important cause of perinatal morbidity and mortality. Management of these morbidities associated with PPROM poses a great challenge. However, women should be informed of these complications.

Hospital births, when compared to out-of-hospital births, have generally led to not only a significantly reduced maternal and perinatal mortality and morbidity but also an increase in certain interventions. A trend seems to be emerging, especially in the US where some women are requesting home births, which creates ethical challenges for obstetricians and the health care organizations and policy makers. In the developing world, a completely different reality exists. Home births constitute the majority of deliveries in the developing world. There are severe limitations in terms of facilities, health personnel and deeply entrenched cultural and socio-economic conditions militating against hospital births. As a consequence, maternal and perinatal mortality and morbidity remain the highest, especially in Sub-Saharan Africa (SSA). Midwife-assisted planned home birth therefore has a major role to play in increasing the safety of childbirth in SSA. The objective of this paper is to propose a model that can be used to improve the safety of childbirth in low resource countries and to outline why midwife assisted planned home birth with coordination of hospitals is the preferred alternative to unassisted or inadequately assisted planned home birth in SSA.

To determine the morbidity and mortality due to listeriosis in the United States, the authors undertook an active surveillance project in 1986 to identify all cases in which Listeria monocytogenes was isolated from cultures of ordinarily sterile sites in a population of 34 million persons. The authors estimated that at least 1,700 cases of listeriosis and 450 deaths occurred in the United States in 1986; 27% of these cases occurred in pregnant women, with 22% of perinatal cases resulting in stillbirths or neonatal deaths. The risk of listeriosis in adults (0.5 per 100,000 population) was similar in all regions studied; the incidence of perinatal listeriosis was three times higher in Los Angeles County, California, than in the other areas (24.3/100,000 live births vs. 7.8/100,000 live births). Geographic variation may have resulted from underdiagnosis of perinatal listeriosis in five of the study areas. Multilocus electrophoretic enzyme typing was useful for elucidating the molecular epidemiology of L. monocytogenes; perinatal listeriosis was significantly associated with one group of related strains. Multilocus electrophoretic enzyme typing also identified three clusters representing possible common-source outbreaks. These findings document the substantial morbidity due to listeriosis in the United States; to the extent that sporadic listeriosis is foodborne, this morbidity could be reduced by appropriate preventive measures, particularly in persons known to be at increased risk of infection.

Obstetrical and perinatal outcomes following blastocyst transfer compared to cleavage transfer: a systematic review and meta-analysis.

Is blastocyst transfer safe when compared to cleavage stage embryo transfer regarding obstetric and perinatal outcomes? The clinical equipoise between blastocyst and cleavage stage embryo transfer remains as the evidence associating blastocyst transfer with some adverse perinatal outcomes is of low/very low quality. Extended embryo culture to the blastocyst stage provides some theoretical advantages and disadvantages. While it permits embryo self-selection, it also exposes those embryos to possible harm due to the in vitro environment. Both effectiveness and safety should be weighed to permit evidence-based decisions in clinical practice. This is a systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies reporting perinatal outcomes for singletons comparing the deliveries resulting from blastocyst and cleavage stage embryo transfer. Observational studies were included because the primary outcomes, perinatal mortality and birth defects, are rare and require a large number of participants (>50 000) to be properly assessed. The last electronic searches were last run on 11 March 2016. There were 12 observational studies encompassing 195 325 singleton pregnancies included in the study. No RCT reported the studied outcomes. The quality of the included studies was evaluated according to the Newcastle-Ottawa Scale and the quality of the evidence was evaluated according to GRADE criteria. Blastocyst stage transfer was associated with increased risks of preterm birth (<37 weeks), very preterm birth (<32 weeks), large for gestational age and perinatal mortality, although the latter was only identified from one study. Conversely, blastocyst stage transfer was associated with a decrease in the risks of small for gestational age and vanishing twins, although the latter was reported by only one study. The observational nature of the included studies and some inconsistency and imprecision in the analysis contributed to decreasing our confidence in the estimates. Due to the overall low quality of available evidence, the clinical equipoise between cleavage stage and blastocyst transfer remains. More large well-conducted studies are needed to clarify the potential risks and benefits of blastocyst transfer. As this review was initiated to support global recommendations on best practice, and in light of the challenges in lower resource settings to offer extended culture to blastocyst stage, it is critical to take into consideration these obstetric and neonatal outcomes in order to ensure any recommendation will not result in the overburdening of existing maternal and child health care systems and services. No external funding was either sought or obtained for this study. The authors have no competing interests to declare. CRD42015023910. © The Author 2016.

The hypertensive disorders of pregnancy (HDP; pre-existing hypertension, gestational hypertension, and pre-eclampsia) remain important causes of maternal morbidity and mortality, especially in low- and middle-income countries. The paper summarizes the current state of evidence around possible technologies to support community-based improvements in maternal and perinatal outcomes for women with pre-eclampsia. Through the testing and, where proven, introduction of these technologies, we believe that HDP-related progress toward achieving Millennium Development Goal 5 can best be accelerated. The evidence and discussion are presented under the following headings: (1) prediction; (2) prevention; (3) diagnosis; (4) risk stratification; (5) decision aids; (6) treatment; (7) geographic information systems; (8) communication; and (9) community and patient education. © 2012 International Federation of Gynecology and Obstetrics.

The nonsteroidal estrogenic compound bisphenol A (BPA) is a monomer used in the manufacture of polycarbonate plastics and resins. BPA may be ingested by humans as it reportedly leaches from the lining of tin cans into foods, from dental sealants into saliva, and from polycarbonate bottles into their contents. Because BPA is weakly estrogenic--approximately 10,000-fold less potent than 17beta-estradiol--current environmental exposure levels have been considered orders of magnitude below the dose required for adverse effects on health. Herein we demonstrate measurable effects on the offspring of Sprague-Dawley female rats that were exposed, via their drinking water, to approximately 0.1 mg BPA/kg body weight (bw)/day (low dose) or 1.2 mg BPA/kg bw/day (high dose) from day 6 of pregnancy through the period of lactation. Offspring exposed to BPA exhibited an increase in body weight that was apparent soon after birth and continued into adulthood. In addition, female offspring exposed perinatally to the high dose of BPA exhibited altered patterns of estrous cyclicity and decreased levels of plasma luteinizing hormone (LH) in adulthood. Administration of neither the doses of BPA that caused effects during perinatal exposure nor a 10-fold higher dose was able to evoke a uterotropic response in ovariectomized postpubertal females. These data indicate an increased sensitivity to BPA during the perinatal period and suggest the need for careful evaluation of the current levels of exposure to this compound. PMID:11485865

The purpose of this investigation was to assess detection and treatment rates for perinatal depression among women enrolled in the California State Medicaid (Medi-Cal) program in comparison to female beneficiaries of reproductive age who did not give birth during the same study period. Investigators conducted a retrospective longitudinal cohort analysis of women between the ages of 18 and 39 years old who were continuously enrolled in the Medi-Cal fee-for-service program between January 2006 and December 2009. The perinatal cohort consisted of women with evidence of a live birth occurring between October 2007 and March 2009. The control cohort consisted of women in the same age group and health plan without evidence of pregnancy during this time frame. The primary outcome of this investigation was diagnosis of depression during 3 contiguous 9-month time frames: immediately prior to presumed conception, during pregnancy, and throughout the postpartum period. Secondary outcomes included within-group and cohort comparisons of treatment patterns (antidepressant or psychotherapy). A multivariable analysis of demographic factors predicting depression diagnosis or treatment was conducted as well. A total of 6030 women was identified in the perinatal cohort, and 56,709 women were included in the control group. The perinatal cohort was significantly less likely than nonpregnant controls to receive a diagnosis of depression both during pregnancy (prevalence=1.6% vs 3.5%; OR=0.45; 95% CI=0.35-0.55) and postpartum (2.2% vs 3.6%; OR=0.59; 95% CI=0.50-0.71). Similar differences were noted in antidepressant prescribing patterns apparent during these 2 time frames. A subgroup analysis of women who received a depression diagnosis revealed that only 48% of the perinatal cohort was provided any treatment during pregnancy (vs 72% of the control group; p<0.0001) or postpartum (57% vs 73%; p<0.0001). Specific demographic factors predicting a lower prevalence of depression detection or treatment included Hispanic descent, age <25 years, or primary residence in an rural setting. Depression was often overlooked and undertreated among women who are pregnant or postpartum in comparison to services delivered to similar nonpregnant controls. Significant disparities in the healthcare received by certain subpopulations of perinatal women suggest that research into barriers to care and subsequent interventions are warranted.

Births in midwife-led institutions may reduce the frequency of medical interventions and provide cost-effective care, while larger institutions offer medically and technically advanced obstetric care. Unplanned births outside an institution and intrapartum stillbirths have frequently been excluded in previous studies on adverse outcomes by place of birth. The objective of the study was to assess peripartum mortality by place of birth and travel time to obstetric institutions, with the hypothesis that centralization reduces institution availability but improves mortality. This was a national population-based retrospective cohort study of all births in Norway from 1999 to 2009 (n = 648,555) using data from the Medical Birth Registry of Norway and Statistics Norway and including births from 22 gestational weeks or birthweight ≥500 g. Main exposures were travel time to the nearest obstetric institution and place of birth. The main clinical outcome was peripartum mortality, defined as death during birth or within 24 hours. Intrauterine fetal deaths prior to start of labor were excluded from the primary outcome. A total of 1586 peripartum deaths were identified (2.5 per 1000 births). Unplanned birth outside an institution had a 3 times higher mortality (8.4 per 1000) than institutional births (2.4 per 1000), relative risk, 3.5 (95% confidence interval, 2.5-4.9) and contributed 2% (95% confidence interval, 1.2-3.0%) of the peripartum mortality at the population level. The risk of unplanned birth outside an institution increased from 0.5% to 3.3% and 4.5% with travel time <1 hour, 1-2 hours, and >2 hours, respectively. In obstetric institutions the mortality rate at term ranged from 0.7 per 1000 to 0.9 per 1000. Comparable mortality rates in different obstetric institutions indicated well-functioning routines for referral. Unplanned birth outside an institution was associated with increased peripartum mortality and with long travel time to obstetric institutions. Structural determinants have an important impact on perinatal health in high-income countries and also for low-risk births. The results show the importance of skilled birth attendance and warrant attention from clinicians and policy makers to negative consequences of reduced access to institutions.

Description of mothers' characteristics, obstetricians' practices, and PPROM-linked mortality in all 81 maternity hospitals in the Rhône-Alpes Region, over a period of 2 years. Prospective cohort study of 598 women with PPROM between 24 and 34 weeks' gestation, leading to 680 births. At time of PPROM, collection of mothers' socio-economic characteristics, medical and obstetric histories and PPROM circumstances. Collection of perinatal management, neonates' medical status and postnatal referral. The birth rate after PPROM between 24 and 34 weeks' gestation was 0.47% (95% CI: 0.42-0.48). Sixty percent of PPROM occurred before 32 weeks' gestation and 98% of births before 37 weeks. The incidence of previous PPROM was 14.3%. Antibiotics, corticosteroids, and tocolytics were given to 82, 78, and 52% of women, respectively. The rate of antibiotics and antenatal corticosteroids varied with gestational age (lower rates for antibiotics just after the limit of viability (23-24 weeks) and after 32 weeks, higher rates of corticosteroids between 26 and 30 weeks). The PPROM-birth interval became shorter as gestation advanced. The incidence of C-section was 58.7% (n = 270), C-section before labour being the most frequent mode of delivery. Sixty-seven percent of neonates were born in Level-3 hospitals. The overall neonatal mortality rate at 28 days decreased with gestational age at PPROM, and was 17.2% (16/93), 3% (6/200), and 0.41% (1/241) at 24-27, 28-31 and 32-33 weeks of PPROM, respectively. After PPROM, antibiotics and antenatal corticosteroids were widely used in our cohort, and C-section rates were elevated. With that up-to-date management, the perinatal mortality rate was less than 3% following PPROM after 28 weeks' gestation.

Previous studies suggest that high risk and low birthweight babies have better outcomes if born in hospitals with level III neonatal intensive care units. Relations between obstetric care, particularly intrapartum interventions and perinatal outcomes, are less well understood, however. To investigate effects of obstetric, paediatric, and demographic factors on rates of hospital stillbirths and neonatal mortality. Cross sectional data on all 65 maternity units in all Thames Regions, 1994-1996, covering 540 834 live births and stillbirths. Hospital level analyses investigated associations between staffing rates (consultant/junior paediatricians, consultant/junior obstetricians, midwives), facilities (consultant obstetrician/anaesthetist sessions, delivery beds, special care baby unit, neonatal intensive care unit cots, etc), interventions (vaginal births, caesarean sections, forceps, epidurals, inductions, general anaesthetic), parental data (parity, maternal age, social class, deprivation, multiple births), and birthweight standardised stillbirth rates and neonatal mortality. Unifactorial analyses showed consistent negative associations between measures of obstetric intervention and stillbirth rates. Some measures of staffing, facilities, and parental data also showed significant associations. Scores for interventional, organisational, and parental variables were derived for multifactorial analysis to overcome the statistical problems caused by high intercorrelations between variables. A higher intervention score and higher number of consultant obstetricians per 1000 births were both independently and significantly associated with lower stillbirth rates. Organisational and parental factors were not significant after adjustment. Only Townsend deprivation score was significantly associated with neonatal mortality (positive correlation). Birthweight adjusted stillbirth rates were significantly lower in units that took a more interventionalist approach and in those with higher levels of consultant obstetric staffing. There were no apparent associations between neonatal death rates and the hospital factors measured here.

To study the incidence, maternal characteristics and outcome of unplanned out-of-institution births (= unplanned births) in Norway. Register-based cross-sectional study. All births in Norway (n = 892 137) from 1999 to 2013 with gestational age ≥22 weeks. Analysis of data from the Medical Birth Registry of Norway from 1999 to 2013. Unplanned births (n = 6062) were compared with all other births (reference group). The annual incidence rate of unplanned births was 6.8/1000 births and remained stable during the period of study. Young multiparous women residing in remote municipalities were at the highest risk of experiencing unplanned births. The unplanned birth group had higher perinatal mortality rate for the period, 11.4/1000 compared with 4.9/1000 for the reference group (incidence rate ratio 2.31, 95% confidence interval 1.82-2.93, p < 0.001). Annual perinatal mortality rate for unplanned births did not change significantly (p = 0.80) but declined on average by 3% per year in the reference group (p < 0.001). The unplanned birth group had a lower proportion of live births in all birthweight categories. Live born neonates with a birthweight of 750-999 g in the unplanned birth group had a more than five times higher mortality rate during the first week of life, compared with reference births in the same birthweight category. Unplanned births are associated with adverse outcome. Excessive mortality is possibly caused by reduced availability of necessary medical interventions for vulnerable newborns out-of-hospital. © 2014 The Authors.

The burden of antenatal heart disease in South Africa: a systematic review

PubMed Central

2012-01-01

Background Maternal mortality in South Africa is rising, and heart conditions currently account for 41 per cent of indirect causes of deaths. Little is known about the burden of heart disease in pregnant South Africans. Methods We systematically reviewed the contemporary epidemiology and peripartum outcomes of heart disease in South African women attending antenatal care. Searches were performed in PubMed, ISI Web of Science, the EBSCO Africa-Wide database, the South African Union Catalogue, and the Current and Completed Research database (South Africa). References of included articles were also hand-searched. Studies reporting epidemiologic data on antenatal heart disease in South Africa were included. Data on morbidity and mortality were also collected. Results Seven studies were included in the systematic review. The prevalence of heart disease ranged from 123 to 943 per 100,000 deliveries, with a median prevalence of 616 per 100,000. Rheumatic valvular lesions were the commonest abnormalities, although cardiomyopathies were disproportionately high in comparison with other developing countries. Peripartum case-fatality rates were as high as 9.5 per cent in areas with limited access to care. The most frequent complications were pulmonary oedema, thromboembolism, and major bleeding with warfarin use. Perinatal mortality ranged from 8.9 to 23.8 per cent, whilst mitral lesions were associated with low birth weight. Meta-analysis could not be performed due to clinical and statistical heterogeneity of the included studies. Conclusion Approximately 0.6 per cent of pregnant South Africans have pre-existing cardiac abnormalities, with rheumatic lesions being the commonest. Maternal and perinatal morbidity and mortality continue to be very high. We conclude this review by summarising limitations of the current literature and recommending standard reporting criteria for future reports. PMID:22463484

Prevalence & consequences of anaemia in pregnancy.

PubMed

Kalaivani, K

2009-11-01

Prevalence of anaemia in India is among the highest in the world. Prevalence of anaemia is higher among pregnant women and preschool children. Even among higher income educated segments of population about 50 per cent of children, adolescent girls and pregnant women are anaemic. Inadequate dietary iron, folate intake due to low vegetable consumption, perhaps low B12 intake and poor bioavailability of dietary iron from the fibre, phytate rich Indian diets are the major factors responsible for high prevalence of anaemia. Increased requirement of iron during growth and pregnancy and chronic blood loss contribute to higher prevalence in specific groups. In India, anaemia is directly or indirectly responsible for 40 per cent of maternal deaths. There is 8 to 10-fold increase in MMR when the Hb falls below 5 g/dl. Early detection and effective management of anaemia in pregnancy can contribute substantially to reduction in maternal mortality. Maternal anaemia is associated with poor intrauterine growth and increased risk of preterm births and low birth weight rates. This in turn results in higher perinatal morbidity and mortality, and higher infant mortality rate. A doubling of low birth weight rate and 2 to 3 fold increase in the perinatal mortality rates is seen when the Hb is <8 g/dl. Intrauterine growth retardation and low birth weight inevitably lead to poor growth trajectory in infancy, childhood and adolescence and contribute to low adult height. Parental height and maternal weight are determinants of intrauterine growth and birth weight. Thus maternal anaemia contributes to intergenerational cycle of poor growth in the offspring. Early detection and effective management of anaemia in pregnancy can lead to substantial reduction in undernutrition in childhood, adolescence and improvement in adult height.

WITHDRAWN: Amnioinfusion for meconium-stained liquor in labour.

PubMed

Hofmeyr, G Justus

2009-01-21

Amnioinfusion aims to prevent or relieve umbilical cord compression during labour by infusing a solution into the uterine cavity. It is also thought to dilute meconium when present in the amniotic fluid and so reduce the risk of meconium aspiration. However, it may be that the mechanism of effect is that it corrects oligohydramnios (reduced amniotic fluid), for which thick meconium staining is a marker. The objective of this review was to assess the effects of amnioinfusion for meconium-stained liquor on perinatal outcome. The Cochrane Pregnancy and Childbirth Group trials register (October 2001) and the Cochrane Controlled Trials Register (Issue 3, 2001) were searched. Randomised trials comparing amnioinfusion with no amnioinfusion for women in labour with moderate or thick meconium-staining of the amniotic fluid. Eligibility and trial quality were assessed by one reviewer. Twelve studies, most involving small numbers of participants, were included. Under standard perinatal surveillance, amnioinfusion was associated with a reduction in the following: heavy meconium staining of the liquor (relative risk 0.03, 95% confidence interval 0.01 to 0.15); variable fetal heart rate deceleration (relative risk 0.65, 95% confidence interval 0.49 to 0.88); and reduced caesarean section overall (relative risk 0.82, 95% confidence interval 0.69 to 1.97). No perinatal deaths were reported. Under limited perinatal surveillance, amnioinfusion was associated with a reduction in the following: meconium aspiration syndrome (relative risk 0.24, 95% confidence interval 0.12 to 0.48); neonatal hypoxic ischaemic encephalopathy (relative risk 0.07, 95% confidence interval 0.01 to 0.56) and neonatal ventilation or intensive care unit admission (relative risk 0.56, 95% confidence interval 0.39 to 0.79); there was a trend towards reduced perinatal mortality (relative risk 0.34, 95% confidence interval 0.11 to 1.06). Amnioinfusion is associated with improvements in perinatal outcome, particularly in settings where facilities for perinatal surveillance are limited. The trials reviewed are too small to address the possibility of rare but serious maternal adverse effects of amnioinfusion.

Background Globally, India contributes the largest share in sheer numbers to the burden of maternal and infant under-nutrition, morbidity and mortality. A major gap in our knowledge is how socio-cultural practices and beliefs influence the perinatal period and thus perinatal outcomes, particularly in the rapidly growing urban setting. Methods and Findings Using data from a qualitative study in urban south India, including in-depth interviews with 36 women who had recently been through childbirth as well as observations of family life and clinic encounters, we explored the territory of familial, cultural and traditional practices and beliefs influencing women and their families through pregnancy, childbirth and infancy. We found that while there were some similarities in cultural practices to those described before in studies from low resource village settings, there are changing practices and ideas. Fertility concerns dominate women’s experience of married life; notions of gender preference and ideal family size are changing rapidly in response to the urban context; however inter-generational family pressures are still considerable. While a rich repertoire of cultural practices persists throughout the perinatal continuum, their existence is normalised and even underplayed. In terms of diet and nutrition, traditional messages including notions of ‘hot’ and ‘cold’ foods, are stronger than health messages; however breastfeeding is the cultural norm and the practice of delayed breastfeeding appears to be disappearing in this urban setting. Marriage, pregnancy and childbirth are so much part of the norm for women, that there is little expectation of individual choice in any of these major life events. Conclusions A greater understanding is needed of the dynamic factors shaping the perinatal period in urban India, including an acknowledgment of the health promoting as well as potentially harmful cultural practices and the critical role of the family. This will help plan culturally appropriate integrated perinatal health care. PMID:25369447

Study objective: Several studies on differences in infant outcome by socioeconomic position have been done, but these have usually been based on ad hoc data linkages. The aim of this paper was to investigate whether socioeconomic differences in perinatal health in Finland could be regularly monitored using routinely collected data from one single register. Design and setting: Since October 1990, the Finnish Medical Birth Register (MBR) has included data on maternal occupation. A special computer program that converted the occupation name into an occupational code and into a socioeconomic position was prepared. Perinatal health was measured with five different indicators. The Finnish MBR data for years 1991 to 1999 (n=565 863 newborns) were used in the study. The study period was divided into three, three year periods to study time trends. Results: An occupational code was derived for 95% of women, but it was not possible to define a socioeconomic position for 22% of women, including, for example, students and housewives (the group "Others"). For the rest, the data showed socioeconomic differences in all perinatal health indicators. Maternal smoking explained up to half of the excess risk for adverse perinatal outcome in the lowest socioeconomic group. The socioeconomic differences narrowed during the 1990s: infant outcome improved in the lowest socioeconomic group, but remained at the same level or even deteriorated in other groups. When comparing the lowest group with the highest group, the odds ratios (OR) adjusted for maternal background characteristics at least halved for prematurity (from 1.32 (95% confidence intervals 1.24 to 1.43) in 1991–1993 to 1.16 (1.08 to 1.25) in 1997–1999), for low birth weight (from 1.49 (1.36 to 1.63) to 1.25 (1.17 to 1.40)), and for perinatal mortality (from 1.79 (1.44 to 2.21) to 1.33 (1.07 to 1.66)). Conclusions: Social inequality in perinatal health outcomes exists in Finland, but seems to have diminished in the 1990s. These data showed that routinely collected birth register data provide a good source for studies on socioeconomic health differences in the perinatal period, but that uncertainty, mainly attributable to the large group of women with difficult to classify socioeconomic status, remains.

While increase in the number of women delivering in health facilities has been rapid, the quality of obstetric and neonatal care continues to be poor in India, contributing to high maternal and neonatal mortality. The USAID ASSIST Project supported health workers in 125 public health facilities (delivering approximately 180,000 babies per year) across six states to use quality improvement (QI) approaches to provide better care to women and babies before, during and immediately after delivery. As part of this intervention, each month, health workers recorded data related to nine elements of routine care alongside data on perinatal mortality. We aggregated facility level data and conducted segmented regression to analyse the effect of the intervention over time. Care improved to 90-99% significantly (p < 0.001) for eight of the nine process elements. A significant (p < 0.001) positive change of 30-70% points was observed during post intervention for all the indicators and 3-17% points month-to-month progress shown from the segmented results. Perinatal mortality declined from 26.7 to 22.9 deaths/1000 live births (p < 0.01) over time, however, it is not clear that the intervention had any significant effect on it. These results demonstrate the effectiveness of QI approaches in improving provision of routine care, yet these approaches are underused in the Indian health system. We discuss the implications of this for policy makers.

Background Elevated exposure to the essential element manganese (Mn) can be toxic. Manganese concentrations in ground water vary considerably, and reported associations between Mn and early-life mortality and impaired development have raised concern. We assessed the effects of drinking water Mn exposure during pregnancy upon fetal and infant survival. Methods In this population-based cohort study, we identified the outcomes of pregnancies registered between February 2002 and April 2003 in Matlab, Bangladesh. Using inductively coupled plasma mass spectrometry, we measured the concentrations of Mn and other elements in the pregnant women’s drinking water. Results A total of 1,875 women were included in the analysis of spontaneous abortions (n=158) and 1,887 women in the perinatal mortality analysis (n=70). Water Mn ranged from 3.0–6,550 µg/L (median=217 µg/L). The adjusted odds ratio (OR) for spontaneous abortion was 0.65 (95% CI 0.43–0.99) in the highest water Mn tertile (median=1,292 µg/L) as compared to the lowest tertile (median=56 µg/L). The corresponding OR for perinatal mortality was 0.69 (95% CI 0.28–1.71), which increased to 0.78 (95% CI 0.29–2.08) after adjustment for BMI and place of delivery (home/health facility; n=1,648). Conclusions Elevated water Mn concentrations during pregnancy appear protective for the fetus, particularly in undernourished women. This effect may be due to the element’s role in antioxidant defense. PMID:24066101

Recently assisted reproduction techniques are more common, which increases multiple pregnancies and adverse perinatal outcomes. Some authors report increased mortality in multiple pregnancies products obtained by techniques of assisted reproduction vs. conceived spontaneously, although other authors found no significant difference. To evaluate mortality rate of multiple pregnancies comparing those obtained by assisted reproduction vs. spontaneous conception. Retrospective, observational and comparative study. We included pregnant women with 3 or more products that went to the Unidad Médica de Alta Especialidad No. 23, IMSS, in Monterrey, NL (Mexico), between 2002-2008. We compared the number of complicated pregnancies and dead products obtained by a technique of assisted reproduction vs. spontaneous. 68 multiple pregnancies were included. On average, spontaneously conceived fetuses had more weeks of gestation and more birth weight than those achieved by assisted reproduction techniques (p = ns). 20.5% (14/68) of multiple pregnancies had one or more fatal events: 10/40 (25%) by assisted reproduction techniques vs. 4/28 (14%) of spontaneous multiple pregnancies (p = 0.22). 21/134 (16%) of the products conceived by assisted reproduction techniques and 6/88 (7%) of spontaneous (p < 0.03) died. 60% of all multiple pregnancies were obtained by a technique of assisted reproduction and 21% of the cases had one or more fatal events (11% more in pregnancies achieved by assisted reproduction techniques). 12% of the products of multiple pregnancies died (9% more in those obtained by a technique of assisted reproduction).

The aim of this study was to describe the distribution of magnetic resonance imaging (MRI) patterns in a large population sample of children with cerebral palsy (CP) and to examine associations between MRI patterns, and antenatal and perinatal variables. Data were retrieved from the Victorian CP Register for 884 children (527 males, 357 females) born between 1999 and 2006. Postneonatal MRI was classified for 594 children. For 563 children (329 males, 234 females) for whom classification was to a single MRI pattern, the frequency of each variable was compared between patterns and with the population frequency. White matter injury was the most common MRI pattern (45%), followed by grey matter injury (14%), normal imaging (13%), malformations (10%), focal vascular insults (9%), and miscellaneous patterns (7%). Parity, birth gestation, level of neonatal care, Apgar score, and time to established respiration varied between MRI patterns (p<0.01). Nulliparity was most strongly associated with focal vascular insults, whereas multiparity was associated only with malformations. Grey matter injury was not associated with birth in a tertiary unit, but was strongly associated with severe perinatal compromise. The frequency of neonatal seizures and of nursery admissions was lowest among children with malformations. As known risk factors for CP are differentially associated with specific MRI patterns, future exploration of causal pathways might be facilitated when performed in pathogenically defined groups. © 2013 Mac Keith Press.

To describe communication and access barriers encountered by allophone women of different migration backgrounds in the Swiss maternity care services, from the perspective of users, healthcare professionals and intercultural interpreters. In addition to the challenges of maternal adjustment, pregnant migrant women must also deal with an unfamiliar health service system. Some must overcome language barriers and the stress of uncertain residence status. Limited access to maternity care increases perinatal morbidity and mortality. Almost 10% of foreigners speak none of Switzerland's official languages. Factors that facilitate or hinder communication between migrant women and perinatal healthcare professionals are under-studied and must be understood if we are to overcome those barriers in clinical practice. Qualitative exploratory study with quantitative sub-study. Participants will be drawn from German to speaking regions of Switzerland. We will conduct focus group discussions and semi-structured interviews with users in their own language (Albanian and Tigrinya) and with healthcare professionals and intercultural interpreters (March-June 2016), then perform Thematic Analysis on the data. In the sub-study, midwives will report their experience of using a telephone interpreting service during postnatal home visits in a questionnaire (October 2013-March 2016). Data will be analysed with descriptive statistics. Our study will reveal patterns in communications between allophone migrant women and healthcare providers and communication barriers. By incorporating multiple perspectives, we will describe the challenges all parties face. Our results will inform those who draft recommendations to improve provision of maternity care to allophone women and their families.

Association of Apgar scores with death and neurologic disability

PubMed Central

Ehrenstein, Vera

2009-01-01

Apgar score was devised with the aim to standardize the assessment of newborns. It has been used worldwide to evaluate infants’ condition immediately after birth, to determine their need for resuscitation, and to evaluate the effectiveness of resuscitation. Apgar score was never intended for prediction of outcome beyond the immediate postnatal period; however, since low scores correlate with prenatal and perinatal adversities, multiple studies have examined the relation between the value of Apgar score and duration of low (<7) Apgar score and subsequent death or neurologic disability. This article reviews such studies. The author concludes that the overall evidence shows consistent association of low Apgar scores with increased risks of neonatal and infant death and with neurologic disability, including cerebral palsy, epilepsy, and cognitive impairment. Dose-response patterns have been shown for the value of Apgar score and duration of low score and the outcomes of mortality and neurologic disability. The association of Apgar score <7 at five minutes with increased risks of neurologic disability seems to persist many years postnatally. Some corresponding relative risk estimates are large (eg, four to seven for epilepsy or more than 20 for cerebral palsy), while others are modest (eg, 1.33 for impaired cognitive function). The absolute risks, however, are low (<5% in for most neurologic conditions), and majority of surviving babies with low Apgar scores grow up without disability. The low magnitude of absolute risks makes Apgar score a poor clinical predictor of long-term outcome. Nevertheless, the observed associations point to the importance of fetal and perinatal periods for neurodevelopment. PMID:20865086

Macrosomia has been defined in various ways by obstetricians and researchers. The purpose of the present study was to search for a definition of macrosomia through an outcome-based approach. In a study of 30,831,694 singleton term live births and 38,053 stillbirths in the U.S. Linked Birth-Infant Death Cohort datasets (1995-2004), we compared the occurrence of stillbirth, neonatal death, and 5-min Apgar score less than four in subgroups of birthweight (4000-4099 g, 4100-4199 g, 4200-4299 g, 4300-4399 g, 4400-4499 g, 4500-4999 g vs. reference group 3500-4000 g) and birthweight percentile for gestational age (90th-94th percentile, 95th-96th, and ≥ 97th percentile, vs. reference group 75th-90th percentile). There was no significant increase in adverse perinatal outcomes until birthweight exceeded the 97th percentile. Weight-specific odds ratios (ORs) elevated substantially to 2 when birthweight exceeded 4500 g in Whites. In Blacks and Hispanics, the aORs exceeded 2 for 5-min Apgar less than four when birthweight exceeded 4300 g. For vaginal deliveries, the aORs of perinatal morbidity and mortality were larger for most of the subgroups, but the patterns remained the same. A birthweight greater than 4500 g in Whites, or 4300 g in Blacks and Hispanics regardless of gestational age is the optimal threshold to define macrosomia. A birthweight greater than the 97th percentile for a given gestational age, irrespective of race is also reasonable to define macrosomia. The former may be more clinically useful and simpler to apply.

Troponin-T is a commonly used cardiac biomarker, which could be useful in perinatal asphyxia. We aimed to analyze troponin-T concentrations in asphyxiated neonates and to correlate the concentrations with clinical outcomes. Data were collected from electronic medical records of neonates diagnosed with perinatal asphyxia over a period of four years. There were 63 neonates with moderate to severe encephalopathy, in whom serial troponin-T concentrations had been done on days 1, 3, and 7. 53 (84%) asphyxiated infants had troponin-T concentration >100 pg/ml at 2-4 h of life.The difference in troponin-T concentrations between moderate and severe encephalopathy was not statistically significant (173 vs. 263 pg/ml, p value 0.40). The difference in the concentrations at 72 hours between cooled and non-cooled neonates was not significant (48.5 vs. 62.5 pg/ml, p value 0.22). Troponin-T concentration was significantly higher in babies with hypotensive shock and hepatic injury, but not acute kidney injury. There was no significant correlation between troponin-T and the extent of resuscitation needed.Troponin-T concentration on day 1 of life was significantly higher in babies who died than who survived (407 vs. 168 pg/ml, p value 0.03). ROC curve for troponin-T to predict mortality had an area under the curve (AUC) of 0.803; the best cut-off value (190 pg/ml) had 82% sensitivity and 80% specificity. There was no significant difference in troponin-T concentrations between cooled and non-cooled neonates. Troponin-T concentration had a good predictive accuracy for mortality before discharge.

Perinatal hypoxia is one of the leading causes of perinatal mortality in developing countries. Both apgar score and arterial blood pH predict the neonatal mortality in asphyxia. Apgar score alone does not predict neurologic outcome and as it is influenced by various factors. This study was conducted to evaluate the utility and sensitivity of urinary uric acid to creatinine ratio (UA/Cr ratio) in asphyxia diagnosis, compared to invasive Arterial Blood Gas (ABG) analysis. To assess the urinary uric acid/creatinine ratio as an additional marker for perinatal asphyxia compared with ABG analysis in apgar score monitoring. The present case control study was conducted at a teaching hospital in Central Gujarat. Data of 40 healthy newborns and 40 asphyxiated newborns were collected. In absence of regional estimates, a sample of size 39 was required to attain a power of 80% at 5% alpha (type I error) considering a moderate effect size of 0.65. (UA/Cr) ratio was measured from the spot urine sample collected during 24-72 hours of birth. Statistical analysis was performed by Independent t-test, Pearson's correlation coefficient (r) and Receiver Operating Characteristic (ROC) plots. The mean (UA/Cr ratio) (2.75±0.18 vs 1.78±0.23) is significantly higher in asphyxiated group than in the control group (p<0.0001). Urinary UA/Cr ratio had negative correlation with blood pH (r= -0.27, p=0.18), which was not significant (p>0.05). Urinary UA/Cr ratio with criterion of >2.3 had 100% sensitivity, 100% specificity with AUC of 1 (p<0.0001) had a better predictive value. Apgar score is usually reduced in neonates with congenital anomalies and premature neonates. Hence, it is preferable that the clinical diagnosis of asphyxia by apgar scores be supported by other investigations so that early decision can be taken about the level of care the baby needs. pH, lactates and base deficits change with establishment of respiration following resuscitation. However, pH, lactate, base deficit estimations are invasive and need rapid estimations. Non-invasive urinary UA/Cr ratio may be an answer to these issues as it easy, economical and equally efficient.

Pregnant patients with chronic renal insufficiency treated with hemodialysis experience adverse perinatal results. To compare perinatal complications of patients with chronic renal insufficiency undergoing hemodialysis who become pregnant vs. the complications of women with chronic renal insufficiency not undergoing dialysis but who then require dialysis during gestation. Transversal and retrospective study that included three patients with chronic renal insufficiency on chronic hemodialysis who became pregnant (group A) and three patients with chronic renal insufficiency without hemodialysis at the time of conception but who required dialysis during gestation (group B). Perinatal results were compared. Statistical analysis was performed with measures of central tendency and dispersion and Student t-test. Group A had 25 sessions vs. group B with 29 hemodialysis sessions (p = 0.88). Maternal complications were anemia 100% (six cases), Cesarean delivery 83.3% (group A 2 cases vs. group B 2 cases), preeclampsia 50% (group A 2 cases vs. group B 1 case), uncontrolled hypertension 50% (group A 2 cases vs. group B 1 case), preterm delivery 50% (group A 2 cases vs. group B 1 case), transfusion 33.3% (group A 2 cases), polyhydramnios 33.3% (group A 1 case vs. group B 1 case) and abortion 16.6% (group A 1 case). Fetal complications included fetal loss 16.6% (group A 1 case), neonatal mortality 33.3% (group A 1 cases vs. group B 1 case), prematurity 50% (group A2 cases vs. group B 1 case), fetal distress 50% (group A 1 case vs. group B 2 cases), respiratory failure 33.3% (group A 2 cases) and fetal growth restriction 16.6% (group A 1 case). Frequency of perinatal complications is elevated in both groups.

Background Existing studies have suggested decreased adherence and rebound in mortality in perinatally HIV-infected adolescents receiving antiretroviral therapy (ART) as compared to adults and young children. Methods We used both quantitative and qualitative approaches to identify factors influencing adherence among perinatally infected adolescents in Thailand. We analyzed data from 568 pairs of perinatally infected adolescents (aged 12–19) and their primary caregivers in the Teens Living With Antiretrovirals (TEEWA) study, a cross-sectional survey conducted in 2010–2012. We also conducted 12 in-depth interviews in 2014 with infected adolescents or their primary caregivers to elicit experiences of living with long-term ART. Results From the quantitative analysis, a total of 275 (48.4%) adolescents had evidence of suboptimal adherence based on this composite outcome: adolescents self-reported missing doses in the past 7 days, caregiver rating of overall adherence as suboptimal, or latest HIV-RNA viral load ≥1000 copies/ml. In multivariate logistic regression analysis, younger age, having grandparents or extended family members as the primary caregiver, caregiver-assessed poor intellectual ability, having a boy/girlfriend, frequent online chatting, self-reported unhappiness and easiness in asking doctors questions were significantly associated with suboptimal adherence. From the in-depth interviews, tensed relationships with caregivers, forgetfulness due to busy schedules, and fear of disclosing HIV status to others, especially boy/girlfriends, were important contributors to suboptimal adherence. Social and emotional support and counseling from peer group was consistently reported as a strong adherence-promoting factor. Conclusion Our findings highlight unique barriers of ART adherence among the perinatally infected adolescents. Future interventions should be targeted at helping adolescents to improve interpersonal relationships and build adaptive skills in recognizing and addressing challenging situations related to ART taking.

Maternal and newborn mortality rates remain unacceptably high, especially where the majority of births occur in home settings or in facilities with inadequate resources. The introduction of emergency obstetric and newborn care services has been proposed by several organizations in order to improve pregnancy outcomes. However, the effectiveness of emergency obstetric and neonatal care services has never been proven. Also unproven is the effectiveness of community mobilization and community birth attendant training to improve pregnancy outcomes. We have developed a cluster-randomized controlled trial to evaluate the impact of a comprehensive intervention of community mobilization, birth attendant training and improvement of quality of care in health facilities on perinatal mortality in low and middle-income countries where the majority of births take place in homes or first level care facilities. This trial will take place in 106 clusters (300-500 deliveries per year each) across 7 sites of the Global Network for Women's and Children's Health Research in Argentina, Guatemala, India, Kenya, Pakistan and Zambia. The trial intervention has three key elements, community mobilization, home-based life saving skills for communities and birth attendants, and training of providers at obstetric facilities to improve quality of care. The primary outcome of the trial is perinatal mortality. Secondary outcomes include rates of stillbirth, 7-day neonatal mortality, maternal death or severe morbidity (including obstetric fistula, eclampsia and obstetrical sepsis) and 28-day neonatal mortality. In this trial, we are evaluating a combination of interventions including community mobilization and facility training in an attempt to improve pregnancy outcomes. If successful, the results of this trial will provide important information for policy makers and clinicians as they attempt to improve delivery services for pregnant women and newborns in low-income countries.

To assess the risks of and factors associated with mortality, loss to follow-up, and changing regimens after children with HIV infected perinatally initiate combination antiretroviral therapy (cART) in Latin America and the Caribbean. This 1997-2013 retrospective cohort study included 1174 antiretroviral therapy-naïve, perinatally infected children who started cART age when they were younger than 18 years of age (median 4.7 years; IQR 1.7-8.8) at 1 of 6 cohorts from Argentina, Brazil, Haiti, and Honduras, within the Caribbean, Central and South America Network for HIV Epidemiology. Median follow-up was 5.6 years (IQR 2.3-9.3). Study outcomes were all-cause mortality, loss to follow-up, and major changes in cART. We used Cox proportional hazards models stratified by site to examine the association between predictors and times to death or changing regimens. Only 52% started cART at younger than 5 years of age; 19% began a protease inhibitor. At cART initiation, median CD4 count was 472 cells/mm 3 (IQR 201-902); median CD4% was 16% (IQR 10-23). Probability of death was high in the first year of cART: 0.06 (95% CI 0.04-0.07). Five years after cART initiation, the cumulative mortality incidence was 0.12 (95% CI 0.10-0.14). Cumulative incidences for loss to follow-up and regimen change after 5 years were 0.16 (95% 0.14-0.18) and 0.30 (95% 0.26-0.34), respectively. Younger children had the greatest risk of mortality, whereas older children had the greatest risk of being lost to follow-up or changing regimens. Innovative clinical and community approaches are needed for quality improvement in the pediatric care of HIV in the Americas. Copyright © 2016 Elsevier Inc. All rights reserved.

Pre-pregnancy care for women with pre-gestational diabetes mellitus: a systematic review and meta-analysis

PubMed Central

2012-01-01

Background Pre-gestational diabetes mellitus is associated with increased risk for maternal and fetal adverse outcomes. This systematic review was carried out to evaluate the effectiveness and safety of pre-pregnancy care in improving the rate of congenital malformations and perinatal mortality for women with pre-gestational diabetes mellitus. Methods We searched the following databases, MEDLINE, EMBASE, WEB OF SCIENCE, Cochrane Library, including the CENTRAL register of controlled trials and CINHAL up to December 2011, without language restriction, for any pre-pregnancy care aiming at health promotion, glycemic control and screening and treatment of diabetes complications in women with type I or type II diabetes mellitus. Study design were trials (randomized and non-randomized), cohort and case–control studies. Results Of the 2452 title scanned 54 full papers were retrieved of those 21 studies were included in this review. Twelve cohort studies at low and medium risk of bias, with 3088 women, were included in the meta-analysis. Meta-analysis suggested that pre-pregnancy care is effective in reducing congenital malformation, Risk Ratio (RR) 0.25 (95% CI 0.16-0.37), number needed to treat (NNT) 19 (95% CI 14–24), and perinatal mortality RR 0.34 (95% CI 0.15-0.75), NNT = 46 (95% CI 28–115). Pre-pregnancy care lowers glycosylated hemoglobin A1c (HbA1c) in the first trimester of pregnancy by an average of 1.92% (95% CI −2.05 to −1.79). However women who received pre-pregnancy care were at increased risk of hypoglycemia during the first trimester of pregnancy RR 1.51 (95% CI 1.15-1.99). Conclusion Pre-pregnancy care for women with pre-gestational type 1 or type 2 diabetes mellitus is effective in improving rates of congenital malformations, perinatal mortality and in reducing maternal HbA1C in the first trimester of pregnancy. Pre-pregnancy care might cause maternal hypoglycemia in the first trimester of pregnancy. PMID:22978747

Population based health surveys in Peru show that the general fertility rates, proportion of pregnant adolescents, and maternal and child morbidity are higher in the jungle regions than in other parts of the country. Endemic intestinal parasitic diseases increase the risk of anemia in pregnant women already suffering from iron, folic acid, and other nutritional deficiencies. This is the most common complication of pregnancy in many Latin American countries and is often associated with premature labor, low birthweight, and perinatal mortality. There are very few studies on this subject based on jungle populations and no reliable estimates of the prevalence of anemia in local pregnant women. The present study was designed to determine the prevalence of anemia in pregnant women attending the Regional Hospital in Pucallpa, located in the Peruvian jungle, from January 1993 to June 1995. This cross-sectional study, which was based on the registries of prenatal and childbirth services encompassing 1,015 pregnant women, looked into the potential association between anemia and such variables as the mother's chronological age, schooling, previous pregnancies, and weight at the beginning of pregnancy. Maternal hemoglobin levels were compared with the newborns' weight at birth. The prevalence of anemia in this population sample was 70.1%. This value was not modified when adjusted for maternal age, schooling, or interval between births. Anemia prevalence was directly related to the number of previous pregnancies and inversely related to weight gain during pregnancy. The perinatal mortality rate was 37.7 per 1,000 births. Neither this rate nor the birthweights were associated with the mother's degree of anemia. A multivariate regression analysis showed that maternal body weight at the start of pregnancy (P = 0.0001), weight gain during pregnancy (P = 0.0001), and the number of pregnancies (P = 0.008) are predictors of birthweight. Results showed that the high prevalence of anemia in Pucallpa's pregnant women is not associated with low birthweight or a high perinatal mortality rate. Future studies should investigate the principal causes of anemia in the pregnant women of Pucallpa and how the disease affects the psychomotor development of their offspring.

This paper aims to study the pattern of perinatal depressive symptomatology and determine the predictive power of second trimester perinatal depressive symptoms for future perinatal periods. A population-based sample of 2,178 women completed the Edinburgh Postnatal Depression Scale (EPDS) in the second and third trimesters and at 6 weeks postpartum. Repeated measures ANOVAs were used to determine the EPDS scores across three stages. The predictive power of the second trimester EPDS score in identifying women with an elevated EPDS score in the third trimester and at 6 weeks postpartum were determined. The predictive power of the second trimester EPDS score was further assessed using stepwise logistic regression and receiver operator characteristic curves. EPDS scores differed significantly across three stages. The rates were 9.9%, 7.8%, and 8.7% for an EPDS score of >14 in the second and third trimesters and at 6 weeks postpartum, respectively. Using a cut-off of 14/15, the second trimester EPDS score accurately classified 89.6% of women in the third trimester and 87.2% of those at 6 weeks postpartum with or without perinatal depressive symptomatology. Women with a second trimester EPDS score >14 were 11.78 times more likely in the third trimester and 7.15 times more likely at 6 weeks postpartum to exhibit perinatal depressive symptomatology after adjustment of sociodemographic variables. The area under the curve for perinatal depressive symptomatology was 0.85 in the third trimester and 0.77 at 6 weeks postpartum. To identify women at high risk for postpartum depression, healthcare professionals could consider screening all pregnant women in the second trimester so that secondary preventive intervention may be implemented.

Evidence suggests that educational differences in perinatal outcomes have increased in some countries (Eastern Europe) while remained stable in others (Scandinavian countries). However, less is known about the experience of Southern Europe. This study aims to evaluate the association between maternal education and perinatal outcomes derived from birthweight (low birthweight and macrosomia) and gestational age (pre-term and post-term births) among Spaniards living in the Autonomous Community of Andalusia during the period 2001-2011 (around 19 % of births in Spain); and to evaluate whether the educational differences narrowed or widened during that period, which includes both an economic boom (2001-2008) and the global economic crisis (2009-2011). This study uses the Andalusian Population Longitudinal Database and the Vital Statistics Data provided by the Spanish National Statistics Institute. We study live and singleton births of Spanish mothers who lived in Andalusia at the time of delivery (n = 404,951). ORs with 95 % confidence intervals (crude and adjusted) were estimated using multinomial regression models. A negative educational gradient is observed in all perinatal outcomes studied (i.e., the higher the educational status, the lower the risk of negative perinatal outcomes). However, when disaggregating the sample in two periods, the gradient is only statistically significant for pre-term birth during 2001-2008, while a full gradient is observed in all perinatal indicators in the period 2009-2011 with an increase in the educational inequalities in macrosomia and post-term. Further studies are needed in order to confirm whether there is a causal association between the widening of the educational differences in perinatal outcomes and the onset of the economic crisis in Spain, or the widening can be explained by other factors, such as changes in childbearing patterns and the composition of women accessing motherhood.

This study investigated the influence on their mental well-being of the perinatal support given by Japanese grandmothers. The Rosenberg self-esteem and the Center for Epidemiologic Studies Depression (CES-D) scales were used to assess grandmothers’ mental well-being before and after their daughters’ childbirth. Of 198 grandmothers, 176 (88.9%) supported their daughters and three patterns of perinatal support were observed: grandmothers’ support at the grandparents’ house before childbirth (n = 95) (Satogaeri bunben; Japanese traditional perinatal support), grandmothers’ support at the grandparents’ house after childbirth (n = 53); and grandmothers’ support at the daughters’ house (n = 28). Those who supported their daughters at the grandparents’ house before childbirth – especially the middle-aged (less than 60 years old) – showed significantly lower scores of self-esteem. Scores of CES-D did not significantly change before and after childbirth in either subgroup of grandmothers. It was concluded that grandmothers play an important role in supporting their daughters, and Satogaeri bunben is a typical event in modern Japan. However, Satogaeri bunben is a burden for middle-aged grandmothers, and we need to support them. PMID:23809679

Perinatal Origins of Adult Disease.

2018-01-01

Epidemiological and experimental studies have shown that the peri-conception period, pregnancy, and infancy are windows of particular sensibility to environmental clues which influence lifelong trajectories across health and disease. Nutrition, stress, and toxins induce epigenetic marks that control long-term gene expression patterns and can be transmitted transgenerationally. Chronic diseases of adulthood such as hypertension, diabetes, and obesity thus have early, developmental origins in the perinatal period. The early epigenome, in interaction with other actors such as the microbiome, add powerful layers of diversity to the biological predisposition generated by the genome. Such "programming" is a normal, adaptive component of development, including in normal pregnancies and births. However, perinatal disease, either maternal (such as pre-eclampsia, ges-tational diabetes, or inflammatory disease) or fetal, and neonatal diseases (such as intrauterine growth restriction and preterm birth) are major conditions of altered programming, translated into an increased risk for chronic disease in these patients when they reach adulthood. Early prevention, optimal perinatal nutrition, and specific follow-up measures are key factors in the early preservation of long-term health. © 2018 S. Karger AG, Basel.

This article presents a historical review of the performance of 23 cesarean sections at the King’s Maternity Hospital and Midwifery School in Zagreb during the 1908-1918 period. Following prenatal screening by midwives and doctors in the hospital, deliveries in high risk pregnant women were performed at maternity hospitals, not at home. The most common indication for cesarean section was narrowed pelvis in 65.2% of women, while postpartum febrile condition was the most common complication in the puerperium. Maternal mortality due to sepsis after the procedure was 8.69% and overall perinatal mortality was 36.3% (stillbirths and early neonatal deaths).

Self-monitoring of blood glucose (SMBG) is recommended as a key component of the management plan for diabetes therapy during pregnancy. No existing systematic reviews consider the benefits/effectiveness of various techniques of blood glucose monitoring on maternal and infant outcomes among pregnant women with pre-existing diabetes. The effectiveness of the various monitoring techniques is unclear. To compare techniques of blood glucose monitoring and their impact on maternal and infant outcomes among pregnant women with pre-existing diabetes. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 November 2016), searched reference lists of retrieved studies and contacted trial authors. Randomised controlled trials (RCTs) and quasi-RCTs comparing techniques of blood glucose monitoring including SMBG, continuous glucose monitoring (CGM) or clinic monitoring among pregnant women with pre-existing diabetes mellitus (type 1 or type 2). Trials investigating timing and frequency of monitoring were also included. RCTs using a cluster-randomised design were eligible for inclusion but none were identified. Two review authors independently assessed study eligibility, extracted data and assessed the risk of bias of included studies. Data were checked for accuracy. The quality of the evidence was assessed using the GRADE approach. This review update includes at total of 10 trials (538) women (468 women with type 1 diabetes and 70 women with type 2 diabetes). The trials took place in Europe and the USA. Five of the 10 included studies were at moderate risk of bias, four studies were at low to moderate risk of bias, and one study was at high risk of bias. The trials are too small to show differences in important outcomes such as macrosomia, preterm birth, miscarriage or death of baby. Almost all the reported GRADE outcomes were assessed as being very low-quality evidence. This was due to design limitations in the studies, wide confidence intervals, small sample sizes, and few events. In addition, there was high heterogeneity for some outcomes.Various methods of glucose monitoring were compared in the trials. Neither pooled analyses nor individual trial analyses showed any clear advantages of one monitoring technique over another for primary and secondary outcomes. Many important outcomes were not reported.1. Self-monitoring versus standard care (two studies, 43 women): there was no clear difference for caesarean section (risk ratio (RR) 0.78, 95% confidence interval (CI) 0.40 to 1.49; one study, 28 women) or glycaemic control (both very low-quality), and not enough evidence to assess perinatal mortality and neonatal mortality and morbidity composite. Hypertensive disorders of pregnancy, large-for-gestational age, neurosensory disability, and preterm birth were not reported in either study.2. Self-monitoring versus hospitalisation (one study, 100 women): there was no clear difference for hypertensive disorders of pregnancy (pre-eclampsia and hypertension) (RR 4.26, 95% CI 0.52 to 35.16; very low-quality: RR 0.43, 95% CI 0.08 to 2.22; very low-quality). There was no clear difference in caesarean section or preterm birth less than 37 weeks' gestation (both very low quality), and the sample size was too small to assess perinatal mortality (very low-quality). Large-for-gestational age, mortality or morbidity composite, neurosensory disability and preterm birth less than 34 weeks were not reported.3. Pre-prandial versus post-prandial glucose monitoring (one study, 61 women): there was no clear difference between groups for caesarean section (RR 1.45, 95% CI 0.92 to 2.28; very low-quality), large-for-gestational age (RR 1.16, 95% CI 0.73 to 1.85; very low-quality) or glycaemic control (very low-quality). The results for hypertensive disorders of pregnancy: pre-eclampsia and perinatal mortality are not meaningful because these outcomes were too rare to show differences in a small sample (all very low-quality). The study did not report the outcomes mortality or morbidity composite, neurosensory disability or preterm birth.4. Automated telemedicine monitoring versus conventional system (three studies, 84 women): there was no clear difference for caesarean section (RR 0.96, 95% CI 0.62 to 1.48; one study, 32 women; very low-quality), and mortality or morbidity composite in the one study that reported these outcomes. There were no clear differences for glycaemic control (very low-quality). No studies reported hypertensive disorders of pregnancy, large-for-gestational age, perinatal mortality (stillbirth and neonatal mortality), neurosensory disability or preterm birth.5.CGM versus intermittent monitoring (two studies, 225 women): there was no clear difference for pre-eclampsia (RR 1.37, 95% CI 0.52 to 3.59; low-quality), caesarean section (average RR 1.00, 95% CI 0.65 to 1.54; I² = 62%; very low-quality) and large-for-gestational age (average RR 0.89, 95% CI 0.41 to 1.92; I² = 82%; very low-quality). Glycaemic control indicated by mean maternal HbA1c was lower for women in the continuous monitoring group (mean difference (MD) -0.60 %, 95% CI -0.91 to -0.29; one study, 71 women; moderate-quality). There was not enough evidence to assess perinatal mortality and there were no clear differences for preterm birth less than 37 weeks' gestation (low-quality). Mortality or morbidity composite, neurosensory disability and preterm birth less than 34 weeks were not reported.6. Constant CGM versus intermittent CGM (one study, 25 women): there was no clear difference between groups for caesarean section (RR 0.77, 95% CI 0.33 to 1.79; very low-quality), glycaemic control (mean blood glucose in the 3rd trimester) (MD -0.14 mmol/L, 95% CI -2.00 to 1.72; very low-quality) or preterm birth less than 37 weeks' gestation (RR 1.08, 95% CI 0.08 to 15.46; very low-quality). Other primary (hypertensive disorders of pregnancy, large-for-gestational age, perinatal mortality (stillbirth and neonatal mortality), mortality or morbidity composite, and neurosensory disability) or GRADE outcomes (preterm birth less than 34 weeks' gestation) were not reported. This review found no evidence that any glucose monitoring technique is superior to any other technique among pregnant women with pre-existing type 1 or type 2 diabetes. The evidence base for the effectiveness of monitoring techniques is weak and additional evidence from large well-designed randomised trials is required to inform choices of glucose monitoring techniques.

To complement available information on mortality in a population Standard Expected Years of Life Lost (SEYLL), an indicator of premature mortality, is increasingly used to calculate the mortality-associated disease burden. SEYLL consider the age at death and therefore allow a more accurate view on mortality patterns as compared to routinely used measures (e.g. death counts). This study provides a comprehensive assessment of disease and injury SEYLL for Hong Kong in 2010. To estimate the SEYLL, life-expectancy at birth was set according to the 2004 Global Burden of Disease study at 82.5 and 80 years for females and males, respectively. Cause of death data for 2010 were corrected for misclassification of cardiovascular and cancer causes. In addition to the baseline estimates, scenario analyses were performed using alternative assumptions on life-expectancy (Hong Kong standard life-expectancy), time-discounting and age-weighting. To estimate a trend of premature mortality a time-series analysis from 2001 to 2010 was conducted. In 2010 524,706.5 years were lost due to premature death in Hong Kong with 58.3% of the SEYLL attributable to male deaths. The three overall leading single causes of SEYLL were "trachea, bronchus and lung cancers", "ischaemic heart disease" and "lower respiratory infections" together accounting for about 29% of the overall SEYLL. Further, self-inflicted injuries (5.6%; ranked 5) and liver cancer (4.9%; ranked 7) were identified as important causes not adequately captured by classical mortality measures. Scenario analyses highlighted that by using a 3% time-discount rate and non-uniform age-weights the SEYLL dropped by 51.6%. Using Hong Kong's standard life-expectancy values resulted in an overall increase of SEYLL by 10.8% as compared to the baseline SEYLL. Time-series analysis indicates an overall increase of SEYLL by 6.4%. In particular, group I (communicable, maternal, perinatal and nutritional) conditions showed highest increases with SEYLL-rates per 100,000 in 2010 being 1.4 times higher than 2001. The study stresses the mortality impact of diseases and injuries that occur in earlier stages of life and thus presents the SEYLL measure as a more sensitive indicator compared to classical mortality indicators. SEYLL provide useful additional information and supplement available death statistics.

There has been concern about rising rates of caesarean section worldwide. This Article reports the third phase of the WHO global survey, which aimed to estimate the rate of different methods of delivery and to examine the relation between method of delivery and maternal and perinatal outcomes in selected facilities in Africa and Latin America in 2004-05, and in Asia in 2007-08. Nine countries participated in the Asia global survey: Cambodia, China, India, Japan, Nepal, Philippines, Sri Lanka, Thailand, and Vietnam. In each country, the capital city and two other regions or provinces were randomly selected. We studied all women admitted for delivery during 3 months in institutions with 6000 or fewer expected deliveries per year and during 2 months in those with more than 6000 deliveries. We gathered data for institutions to obtain a detailed description of the health facility and its resources for obstetric care. We obtained data from women's medical records to summarise obstetric and perinatal events. We obtained data for 109 101 of 112 152 deliveries reported in 122 recruited facilities (97% coverage), and analysed 107 950 deliveries. The overall rate of caesarean section was 27.3% (n=29 428) and of operative vaginal delivery was 3.2% (n=3465). Risk of maternal mortality and morbidity index (at least one of: maternal mortality, admission to intensive care unit [ICU], blood transfusion, hysterectomy, or internal iliac artery ligation) was increased for operative vaginal delivery (adjusted odds ratio 2.1, 95% CI 1.7-2.6) and all types of caesarean section (antepartum without indication 2.7, 1.4-5.5; antepartum with indication 10.6, 9.3-12.0; intrapartum without indication 14.2, 9.8-20.7; intrapartum with indication 14.5, 13.2-16.0). For breech presentation, caesarean section, either antepartum (0.2, 0.1-0.3) or intrapartum (0.3, 0.2-0.4), was associated with improved perinatal outcomes, but also with increased risk of stay in neonatal ICU (2.0, 1.1-3.6; and 2.1, 1.2-3.7, respectively). To improve maternal and perinatal outcomes, caesarean section should be done only when there is a medical indication.

The potential benefits of obstetric ultrasound have yet to be fully realized in sub-Saharan Africa (SSA), despite the region bearing the greatest burden of poor perinatal outcomes. We reviewed the literature for challenges and opportunities of universal access to obstetric ultrasound and explored what is needed to make such access an integral component of maternity care in order to address the massive burden of perinatal morbidity and mortality in SSA. Original peer-reviewed literature was searched in various electronic databases using a ‘realist’ approach. While the available data were inconclusive, they identify many opportunities for potential future research on the subject within the region that can help build a strong case to justify the provision of universal access to ultrasound as an integral component of comprehensive antenatal care.

Although the survival rate for preterm subjects has improved considerably, due to the progress in the field of perinatal medicine, preterm birth is frequently the cause underlying a series of notorious complications: morphological, neurological, ophthalmological, and renal alterations. In addition, it has recently been demonstrated how low gestational age and reduced foetal growth contribute towards an increased cardiovascular risk in preterm neonates. In fact, cardiovascular mortality is higher among former preterm adults than those born at term. This condition is referred to as cardiovascular perinatal programming. In the light of the above, an early, constant, and prolonged cardiological followup programme should be implemented in former preterm individuals. The aim of this paper was to perform a comprehensive literature review about two new emerging conditions predisposing to an increased cardiovascular risk: prematurity and low weight at birth.

The production of a healthy cloned calf is dependent on a multitude of successful steps, including reprogramming mediated by the oocyte, the development of a functional placenta, adequate maternal-fetal interaction, the establishment of a physiological metabolic setting and the formation of a complete set of well-differentiated cells that will eventually result in well-characterised and fully competent tissues and organs. Although the efficiency of nuclear transfer has improved significantly since the first report of a somatic cell nuclear transfer-derived animal, there are many descriptions of anomalies concerning cloned calves leading to high perinatal morbidity and mortality. The present article discusses some our experience regarding perinatal and neonatal procedures for cloned Zebu cattle (B. indicus) that has led to improved survival rates in Nellore cloned calves following the application of such 'labour-intensive technology'.

The fetal development of the mandible is nowadays quite understood, and it is already known that craniofacial growth reaches its highest rate during the first 5 years of postnatal life. However, there are very few data focusing on the perinatal period. Thus, the present article is addressing this concern by studying the mandible morphology and its evolution around the birth with a morphometric method. Thirty-one mandibles modelled in three dimensions from post-mortem CT-scans were analyzed. This sample was divided into two subgroups composed of, respectively, 15 fetuses (aged from 36 gestational weeks), and 16 infants (aged to 12 postnatal weeks). 17 distances, 3 angles, and 8 thicknesses were measured via the prior set of 14 landmarks, illustrating the whole mandible morphology. Although this methodology may depend on the image reconstruction quality, its reliability was demonstrated with low variability in the results. It highlighted two distinct growth patterns around birth: fetuses mandibles do not significantly evolve during the perinatal period, whereas, from the second postnatal weeks, most of the measurements increased in a homogeneous tendency and in correlation with age. The protocol developed in this study highlighted the morphologic evolution of the mandible around birth, identifying a different growth pattern from 2 postnatal weeks, probably because of the progressive activation of masticatory muscles and tongue. However, considering the small sample size, these results should be thorough, so identification and management of anatomic abnormalities could eventually be achieved.

The role of diet and nutritional supplementation in perinatal depression: a systematic review.

This article presents a systematic literature review on whether dietary intake influences the risk for perinatal depression, i.e. depression during pregnancy or post-partum. Such a link has been hypothesized given that certain nutrients are important in the neurotransmission system and pregnancy depletes essential nutrients. PubMed, EMBASE and CINAHL databases were searched for relevant articles until 30 May 2015. We included peer-reviewed studies of any design that evaluated whether perinatal depression is related to dietary intake, which was defined as adherence to certain diets, food-derived intake of essential nutrients or supplements. We identified 4808 studies, of which 35 fulfilled inclusion criteria: six randomized controlled trials, 12 cohort, one case-control and 16 cross-sectional studies, representing 88 051 distinct subjects. Studies were grouped into four main categories based on the analysis of dietary intake: adherence to dietary patterns (nine studies); full panel of essential nutrients (six studies); specific nutrients (including B vitamins, Vitamin D, calcium and zinc; eight studies); and intake of fish or polyunsaturated fatty acids (PUFAs; 12 studies). While 13 studies, including three PUFA supplementation trials, found no evidence of an association, 22 studies showed protective effects from healthy dietary patterns, multivitamin supplementation, fish and PUFA intake, calcium, Vitamin D, zinc and possibly selenium. Given the methodological limitations of existing studies and inconsistencies in findings across studies, the evidence on whether nutritional factors influence the risk of perinatal depression is still inconclusive. Further longitudinal studies are needed, with robust and consistent measurement of dietary intake and depressive symptoms, ideally starting before pregnancy. © 2016 John Wiley & Sons Ltd.

Behavioural effects of prenatal exposure to carbon disulphide and to aromatol in rats.

1985-01-01

The neurotoxic effects of prenatal organosolvent inhalation were studied in rats, because of the expectation that a developing organism may be more sensitive than the adult to the induction of functional deficits. The aim was to determine whether prenatal exposure to the new organosolvent mixture, Aromatol, and the well known neurotoxic carbon disulphide, would impair reflex ontogeny or produce neurobehavioural dysfunctions in the offspring. Development of gait, motor coordination, and activity, avoidance learning and swimming were tested in the offspring of CFY rat mothers, exposed to CS2 inhalation (0, less than 10, 700 and 2000 mg/m3) and to Aromatol (0, 600, 1000 and 2000 mg/m3) on days 7-15 gestation. Prenatal CS2 inhalation induced dose related perinatal mortality of pups. Eye opening and the auditory startle were retarded. There were immature gait, motor incoordination, diminished open field activity and altered behavioural patterns on day 21 and 36 but they were nearly age-appropriate on day 90. As signs of disturbed learning ability, there were diminished performance and lengthened latency of the conditioned avoidance response, related to the concentrations administered. Contrary to expectations, prenatal Aromatol inhalation had no effect on maturation of gait, behaviour patterns, or learning ability.

To evaluate transcervical amnioinfusion for meconium stained amniotic fluid during labour. Multicentre randomised controlled trial. A large urban academic hospital. Electronic fetal heart rate monitoring was not used. Women in labour at term with moderate or thick meconium staining of the amniotic fluid. Transcervical amnioinfusion of 500 mL saline over 30 minutes, then 500 mL at 30 drops per minute. The control group received routine care. Blinding of the intervention was not possible. Caesarean section, meconium aspiration syndrome and perinatal mortality. There was no difference in risk for caesarean section in the two groups (amnioinfusion 9.5% vs control 12.3%; RR 0.84, 95% CI 0.53-1.32). Meconium aspiration syndrome was significantly less frequent in the amnioinfusion group (3.1% vs 12.8%; RR 0.24, 95% CI 0.12-0.48), and there was a trend towards fewer perinatal deaths (1.2% vs 3.6%; RR 0.34, 95% CI 0.11-1.06). Amnioinfusion is technically feasible in a developing country situation with limited intrapartum facilities. In this study amnioinfusion for meconium stained amniotic fluid was associated with striking improvements in perinatal outcome.

The current diagnostic accuracy and perinatal outcome of fetuses with esophageal atresia (EA) continues to be debated. In this review, we report on our experience at a tertiary care fetal center with the prenatal ultrasound diagnosis of EA. Enrollment criteria included a small/absent stomach bubble with a normal or elevated amniotic fluid index between 2005 and 2013. Perinatal outcomes were analyzed and compared to postnatally diagnosed EA cases. Of the 22 fetuses evaluated, polyhydramnios occurred in 73%. Three (14%) died in utero or shortly after birth, but none had EA. In the presence of an absent/small stomach and polyhydramnios, the positive predictive value for EA was 67%. In fetal EA cases confirmed postnatally (group 1, n = 11), there were no differences in gestational age, birthweight, or mortality when compared to postnatally diagnosed infants (group 2, n = 59). Group 1 was associated with long-gap EA, need for esophageal replacement, and increased hospital length of stay. When taken in context with the current literature, we conclude that ultrasound findings suggestive of EA continue to be associated with a relatively high rate of false positives. However, among postnatally confirmed cases, there is an increased risk for long-gap EA and prolonged hospitalization.

Epidemiology of maternal depression, risk factors, and child outcomes in low-income and middle-income countries

Maternal depression, a non-psychotic depressive episode of mild to major severity, is one of the major contributors of pregnancy-related morbidity and mortality. Maternal depression (antepartum or post partum) has been linked to negative health-related behaviours and adverse outcomes, including psychological and developmental disturbances in infants, children, and adolescents. Despite its enormous burden, maternal depression in low-income and middle-income countries remains under-recognised and undertreated. In this Series paper, we systematically review studies that focus on the epidemiology of perinatal depression (ie, during antepartum and post-partum periods) among women residing in low-income and middle-income countries. We also summarise evidence for the association of perinatal depression with infant and childhood outcomes. This review is intended to summarise fi ndings from the existing literature, identify important knowledge gaps, and set the research agenda for creating new generalisable knowledge pertinent to increasing our understanding of the prevalence, determinants, and infant and childhood health outcomes associated with perinatal depression. This review is also intended to set the stage for subsequent work aimed at reinforcing and accelerating investments toward providing services to manage maternal depression in low-income and middle-income countries.

This paper focuses on the role of environmental factors external to the health care system in the occurrence of perinatal deaths in maternity hospitals belonging to the local health system in a city in Greater Metropolitan Rio de Janeiro in 1994. Elements from the political and administrative context that contribute to an understanding of the relationship between failures in health care and structural deficiencies in these maternity hospitals were divided into four groups of variables: distribution of resources, spatial and temporal factors, organizational and managerial features, and action by interest groups. Semi-structured interviews were conducted. The study concluded that poor performance in four groups of variables may have contributed to perinatal mortality: distribution of resources was insufficient to provide quality in health care, especially in private maternity hospitals; there was no formal or informal regional or hierarchical organization of obstetric care in the city; Ministry of Health guidelines were ignored in all four maternity hospitals, while in three of the hospitals there were no admissions procedures and delivery and fetal follow-up listed in their own rules; and the level of actual participation was low.

1994-04-01

Social and environmental factors in Jamaica were compared between 9919 mothers delivering in a 2-month period a singleton who survived the early neonatal period and 1847 mothers who were delivered of a singleton perinatal death in a contiguous 12-month period. Logistic regression showed independent positive statistically significant increased odds of having a perinatal death among mothers who lived in rural parishes, older mothers (aged 30 +), single parents, no other children in the household, large number of adults in the household, mother unemployed, the major wage earner of the household not being in a managerial, professional or skilled non-manual occupation, the household not having sole use of toilet facilities, smaller mothers and those classified as obese or undernourished. Variations were found for different categories of death. Intrapartum asphyxia deaths were not related to union (marital) status, occupation of major wage earner, number of adults nor to the use of the toilet. Antepartum fetal deaths did not vary significantly with occupation of major wage earner or maternal height, but did show a relationship with maternal education, mothers with lowest levels having reduced risk. Deaths from immaturity were significantly related only to occupation of major wage earner, number of children in the household, number of social amenities available (negative relationships) and maternal age (< 17 at highest risk). In conclusion there was little to indicate that social deprivation per se was related to perinatal death, although specific features of the environment showed strong relationships.

OBJECTIVES To test the hypothesis that acidosis at birth is associated with the combined primary outcome of death or neurodevelopmental impairment (NDI) in extremely low birth weight (ELBW) infants, and to develop a predictive model of death/NDI exploring perinatal acidosis as a predictor variable. STUDY DESIGN The study population consisted of ELBW infants born between 2002-2007 at NICHD Neonatal Research Network hospitals. Infants with cord blood gas data and documentation of either mortality prior to discharge or 18-22 month neurodevelopmental outcomes were included. Multiple logistic regression analysis was used to determine the contribution of perinatal acidosis, defined as a cord blood gas with a pH<7 or base excess (BE)<-12, to death/NDI in ELBW infants. In addition, a multivariable model predicting death/NDI was developed. RESULTS 3979 patients were identified of whom 249 had a cord gas pH<7 or BE<-12 mEq/L. 2124 patients (53%) had the primary outcome of death/NDI. After adjustment for confounding variables, pH<7 and BE<-12 mEq/L were each significantly associated with death/NDI (OR=2.5[1.6,4.2]; and OR=1.5[1.1,2.0], respectively). However, inclusion of pH or BE did not improve the ability of the multivariable model to predict death/NDI. CONCLUSIONS Perinatal acidosis is significantly associated with death/NDI in ELBW infants. Perinatal acidosis is infrequent in ELBW infants, however, and other factors are more important in predicting death/NDI. PMID:24554564

The teenage population delivering in Malta during 1983-1986 were identified and the maternal characteristics and obstetric outcome of these patients were statistically compared to those of mothers aged 20-29 years. Teenage mothers were more likely to be primigravida and poor attenders for antenatal care.

Background Uterine rupture is tearing of the uterine wall during pregnancy or delivery. It may extend to partial or whole thickness of the uterine wall. It is usually a case where obstetric care is poor. In extensive damage, death of the baby and sometimes even maternal death are evident. Objective This study assesses associated factors and outcome of uterine rupture at Suhul General Hospital, Tigray Region, Ethiopia, 2016. Methodology A case-control study was conducted by review of data from September 2012 to August 2016. A total of 336 samples were studied after calculating by EPI-INFO using proportion of multiparity (53%) and ratio of 1 : 2 for cases and controls, respectively. Analysis was done using SPSS version 20. Bivariate and multivariate logistic regression was applied with p < 0.05. Result ANC, grand multiparity, malpresentation, and obstructed labor had association, but previous cesarean delivery was not significant. Perinatal mortality was 105 (93%) versus 13 (5.8%) in cases and controls, respectively. Anemia was highest for both groups (53.7% versus 32.1%). Conclusion Majority of uterine rupture is attributed to prolonged or obstructed labor. Cases of uterine rupture had prompt management preventing maternal mortality, but burden of perinatal death is still high. PMID:29403533

We set out to determine which patients admitted for expectant management of early onset severe pre-eclampsia develop abruptio placentae and to compare the perinatal mortality rate of patients who developed abruptio placentae with those who did not have this complication. This was a case controlled study, using gestational age at delivery to select a control group for 69 patients who developed abruptio placentae. The only significant difference on admission was the higher uric acid levels in patients who developed abruptio placentae. Mean admission to delivery intervals were 11.9 and 8.8 days for the control and abruption groups respectively (P = 0.0083). Fifty-eight per cent of the babies in the abruptio placentae group developed late decelerations, as determined by fetal heart rate monitoring compared with 32% in the control group. Lactate dehydrogenase levels before delivery were significantly higher in the abruption group, but it only became elevated shortly before delivery and in the minority of cases. There were two intrauterine and four neonatal deaths in the abruption group and two neonatal deaths in the control group. Late decelerations detected by frequent fetal heart rate monitoring in patients with early onset severe pre-eclampsia is the only early warning of abruptio placentae.

The present study was conducted with the aim to find out the effect of threatened abortion in the current pregnancy on the subsequent perinatal outcome and follow the growth pattern of the fetuses of such complicated pregnancies. The study group consisted of 55 women with threatened abortion and 55 women with normal pregnancies formed the control group. Most of the patients presented at 6-12 weeks' gestation. The fetal growth was monitored by both clinical as well as ultrasound (USG) parameters. The mean growth rates were almost identical throughout gestation. The mean values of each parameter of the study group were found lying with 95% confidence limit values of their control group. The apparent increased incidence of low lying placenta in early pregnancy probably contributed to threatened abortion. There was no significant difference in preterm delivery, low birth-weight and overall perinatal outcome.

There is limited literature on brain imaging studies of children with cerebral palsy (CP) in low and middle income countries. We investigated neuroimaging patterns of children with CP attending a tertiary referral centre in Uganda to determine how they differed from studies reported from high income countries and their relationship with prenatal and postnatal factors. Precontrast and postcontrast computed tomography (CT) scans of 78 CP children aged 2-12 years were conducted using a Philips MX 16-slice CT scanner. Two radiologists, blinded to the patient's clinical status, independently reviewed the scans. Abnormal CT scans were detected in 69% of the children sampled, with very few having primary white matter injuries (4%). Primary grey matter injuries (PGMI) (44%) and normal scans (31%) were most frequent. Children with a history of hospital admission following birth were three times more likely to have PGMI (odds ratio [OR] 2.8; 95% CI 1.1-7.1), suggesting a perinatal period with medical complications. Brain imaging patterns in this group of CP children differed markedly from imaging studies reported from high income countries, suggesting a perinatal aetiology in full-term infants and reduced survival in preterm infants. ©2016 Foundation Acta Paediatrica.

Examples of culture are given in the text and categorised according to the way in which they impact maternal mortality. cultural customs, practices, beliefs and values profoundly influence women's behaviours during the perinatal period and in some cases increase the likelihood of maternal death in childbirth. The four ways in which culture may increase MMR are as follows: directly harmful acts, inaction, use of care and social status. understanding the specifics of how the culture surrounding childbirth contributes to maternal mortality can assist nurses, midwives and other health-care workers in providing culturally competent care and designing effective programs to help decrease MMR, especially in the developing world. Interventions designed without accounting for these cultural factors are likely to be less effective in reducing maternal mortality. Copyright © 2012 Elsevier Ltd. All rights reserved.

To examine the relative importance of antenatal and perinatal variables on short- and long-term outcome of preterm growth restricted fetuses with umbilical artery (UA) Doppler abnormalities. This was a cohort study of 180 neonates with birth weight < 10(th) percentile, gestational age at delivery < 34 weeks and abnormal Doppler ultrasound examination of the UA. Various antenatal and perinatal variables were studied in relation to short- and long-term outcome. Neonatal and overall mortality (up to 2 years of age) were predicted by low gestational age at delivery. Neonatal mortality was additionally predicted by absent or reversed UA end-diastolic flow, while the presence of severe neonatal complications and placental villitis were additional predictors of both infant (between 28 days and 1 year of postnatal life) and overall mortality. Placental villitis was found to be the only predictor of necrotizing enterocolitis. Low gestational age at delivery, male sex, abnormal cardiotocography, absent or reversed UA end-diastolic flow and the HELLP syndrome predicted respiratory distress syndrome. Abnormal neurodevelopmental outcome at 2 years was predicted by low birth weight (< 2.3(rd) percentile), fetal acidosis (UA pH < 7.00), and placental villitis. Less advanced gestation at delivery remains an important predictor of short-term outcome in growth-restricted fetuses. In addition, the presence of placental villitis may aid neonatologists in the early identification of infants at increased risk of necrotizing enterocolitis, death and abnormal neurodevelopment at 2 years of age. Abnormal neurodevelopment was related to low weight and acidosis at birth, indicating that the severity of malnutrition and fetal acidosis affect long-term outcome.

Current management and prevention of malaria in pregnancy: a review.

Pregnant women suffer more frequent and severe malaria than non-pregnant women. Malaria in pregnancy contributes to the high maternal and perinatal morbidity and mortality in Africa. To review the burden and highlight the current management and prevention strategies for control of malaria in pregnancy in Africa. Papers for this review were identified by searches of PubMed and Google, and references from relevant articles. Search terms were "malaria", "malaria in pregnancy", "Malaria during pregnancy" and "antimalarial drug". Only papers published in English between 1983 and 2013 were included. In malarial endemic areas, acquired partial malarial immunity is not effective during pregnancy. Pregnant women are prone to frequent malaria infections which may be severe or asymptomatic but associated with placental parasitization. Malaria contributes 2-15% to maternal anaemia, 13-70% to intrauterine growth restriction, 8-14% to low birth weight, 8-36% to prematurity, 3-8% to infant deaths and 2.9-17.6% to maternal mortality. The control of malaria in pregnancy is currently predicated on three main strategies: 1) Prompt and effective case management of malaria; 2).Use of Insecticide-treated nets; and 3).Intermittent preventive treatment in pregnancy with sulfadoxine-pyrimethamine. Artemisinin-based combined therapy is the recommended treatment for uncomplicated malaria in the second and third trimesters of pregnancy, while quinine is used in the first trimester and for severe cases of malaria at any gestational age. The control of malaria during pregnancy should be an integral part of efforts to reduce maternal and perinatal morbidity and mortality in Africa.

Background Recommended best practice is that economic evaluation of health care interventions should be integral with randomised clinical trials. We performed a cost-consequence analysis of treating women with mild gestational diabetes mellitus by dietary advice, blood glucose monitoring and insulin therapy as needed compared with routine pregnancy care, using patient-level data from a multi-centre randomised clinical trial. Methods Women with a singleton pregnancy who had mild gestational diabetes diagnosed by an oral glucose-tolerance test between 24 and 34 weeks' gestation and their infants were included. Clinical outcomes and outpatient costs derived from all women and infants in the trial. Inpatient costs derived from women and infants attending the hospital contributing the largest number of enrolments (26.1%), and charges to women and their families derived from a subsample of participants from that hospital (in 2002 Australian dollars). Occasions of service and health outcomes were adjusted for maternal age, ethnicity and parity. Analysis of variance was used with bootstrapping to confirm results. Primary clinical outcomes were serious perinatal complications; admission to neonatal nursery; jaundice requiring phototherapy; induction of labour and caesarean delivery. Economic outcome measures were outpatient and inpatient costs, and charges to women and their families. Results For every 100 women with a singleton pregnancy and positive oral glucose tolerance test who were offered treatment for mild gestational diabetes mellitus in addition to routine obstetric care, $53,985 additional direct costs were incurred at the obstetric hospital, $6,521 additional charges were incurred by women and their families, 9.7 additional women experienced induction of labour, and 8.6 more babies were admitted to a neonatal nursery. However, 2.2 fewer babies experienced serious perinatal complication and 1.0 fewer babies experienced perinatal death. The incremental cost per additional serious perinatal complication prevented was $27,503, per perinatal death prevented was $60,506 and per discounted life-year gained was $2,988. Conclusion It is likely that the general public in high-income countries such as Australia would find reductions in perinatal mortality and in serious perinatal complications sufficient to justify additional health service and personal monetary charges. Over the whole lifespan, the incremental cost per extra life-year gained is highly favourable. Trial Registration Australian Clinical Trials Registry ACTRN12606000294550 PMID:17963528

The population of the Pacific Melanesian country of Vanuatu was 234,000 at the 2009 census. Apart from subsistence activities, economic activity includes tourism and agriculture. Current completeness of vital registration is considered too low to be usable for national statistics; mortality and life expectancy (LE) are derived from indirect demographic estimates from censuses/surveys. Some cause of death (CoD) data are available to provide information on major causes of premature death. Deaths 2001-2007 were coded for cause (ICDv10) for ages 0-59 years from: hospital separations (HS) (n = 636), hospital medical certificates (MC) of death (n = 1,169), and monthly reports from community health facilities (CHF) (n = 1,212). Ill-defined causes were 3 % for hospital deaths and 20 % from CHF. Proportional mortality was calculated by cause (excluding ill-defined) and age group (0-4, 5-14 years), and also by sex for 15-59 years. From total deaths by broad age group and sex from 1999 and 2009 census analyses, community deaths were estimated by deduction of hospital deaths MC. National proportional mortality by cause was estimated by a weighted average of MC and CHF deaths. National estimates indicate main causes of deaths <5 years were: perinatal disorders (45 %) and malaria, diarrhea, and pneumonia (27 %). For 15-59 years, main causes of male deaths were: circulatory disease 27 %, neoplasms 13 %, injury 13 %, liver disease 10 %, infection 10 %, diabetes 7 %, and chronic respiratory disease 7 %; and for females: neoplasms 29 %, circulatory disease 15 %, diabetes 10 %, infection 9 %, and maternal deaths 8 %. Infection included tuberculosis, malaria, and viral hepatitis. Liver disease (including hepatitis and cancer) accounted for 18 % of deaths in adult males and 9 % in females. Non-communicable disease (NCD), including circulatory disease, diabetes, neoplasm, and chronic respiratory disease, accounted for 52 % of premature deaths in adult males and 60 % in females. Injuries accounted for 13 % in adult males and 6 % in females. Maternal deaths translate into an annual maternal mortality ratio of 130/100,000 for the period. Vanuatu manifests a double burden of disease with significant proportional mortality from perinatal disorders and infection/pneumonia <5 years and maternal mortality, coupled with significant proportional mortality in adults (15-59 years) from cardiovascular disease (CVD), neoplasms, and diabetes.

Fetal sex is associated with striking differences during in utero development, fetal-to-neonatal transition, and postnatal morbidity and mortality. Male sex fetuses are apparently protected while in utero resulting in a higher secondary sex rate for males than for females. However, during fetal-to-neonatal transition and thereafter in the newborn period, female exhibits a greater degree of maturation that translates into a better capacity to stabilize, less incidence of prematurity and prematurity-associated morbidities, and better long-term outcomes. The present review addresses the influence of sex during gestation and postnatal adaptation that includes the establishment of an adult-type circulation, the initiation of breathing, endurance when confronted with perinatal hypoxia ischemia, and a gender-related different response to drugs. The intrinsic mechanisms explaining these differences in the perinatal period remain elusive and further experimental and clinical research are therefore stringently needed if an individual oriented therapy is to be developed.

Introduction: Obesity and reproduction.

Women bear the predominant burden of our obesogenic environment, with a higher incidence of obesity than men, more impact on their fertility and success with treatment, and significant maternal and perinatal morbidity and mortality. In this series, the causes, consequences, and solutions regarding the obesity pandemic, the mechanisms of the effect of obesity on the female and male, the epigenetic consequences of male obesity, the marked effects on perinatal outcomes, and the effects of weight loss before conception and during pregnancy are explored. Lifestyle modifications, in particular a healthy diet and exercise during the 3-6 months before conception and during treatment, should result in better outcomes than requiring weight loss before fertility treatments. Such fundamental changes toward a healthier lifestyle will achieve steady and sustainable weight loss and long-term benefits for general health. The role of bariatric surgery before pregnancy requires careful consideration. Copyright © 2017 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

The assessment of fetal growth represents a fundamental step towards the identification of the true growth restricted fetus that is associated to important perinatal morbidity and mortality. The possible ways of detecting abnormal fetal growth are taken into consideration in this review and their strong and weak points are discussed. An important debate still remains about how to discriminate between the physiologically small fetus that does not require special surveillance and the truly growth restricted fetus who is predisposed to perinatal complications, even if its parameters are above the cut-off limits established. In this article, we present the clinical tools of fetal growth assessment: Symphyseal-Fundal Height (SFH) measurement, the fetal ultrasound parameters widely taken into consideration when discussing fetal growth: Abdominal Circumference (AC) and Estimated Fetal Weight (EFW); several types of growth charts and their characteristics: populational growth charts, standard growth charts, individualized growth charts, customized growth charts and growth trajectories.

Periodontal disease has been linked with a number of conditions, such as cardiovascular disease, stroke, diabetes and adverse pregnancy outcomes, all likely through systemic inflammatory pathways. It is common in women of reproductive age and gum conditions tend to worsen during pregnancy. Some evidence from observational studies suggests that periodontal intervention may reduce adverse pregnancy outcomes. There is need for a comprehensive Cochrane review of randomised trials to assess the effect of periodontal treatment on perinatal and maternal health. To assess the effects of treating periodontal disease in pregnant women in order to prevent or reduce perinatal and maternal morbidity and mortality. Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 6 October 2016), Cochrane Pregnancy and Childbirth's Trials Register (to 7 October 2016), the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 9) in the Cochrane Library, MEDLINE Ovid (1946 to 6 October 2016), Embase Ovid (1980 to 6 October 2016), and LILACS BIREME Virtual Health Library (Latin American and Caribbean Health Science Information database; 1982 to 6 October 2016). ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials on 6 October 2016. We placed no restrictions on the language or date of publication when searching the electronic databases. We included all randomised controlled trials (RCTs) investigating the effects of periodontal treatment in preventing or reducing perinatal and maternal morbidity and mortality. We excluded studies where obstetric outcomes were not reported. Two review authors independently screened titles and abstracts and extracted data using a prepiloted data extraction form. Missing data were obtained by contacting authors and risk of bias was assessed using Cochrane's 'Risk of bias' tool. Where appropriate, results of comparable trials were pooled and expressed as risk ratios (RR) or mean differences (MD) with 95% confidence intervals (CI) . The random-effects model was used for pooling except where there was an insufficient number of studies. We assessed the quality of the evidence using GRADE. There were 15 RCTs (n = 7161 participants) meeting our inclusion criteria. All the included studies were at high risk of bias mostly due to lack of blinding and imbalance in baseline characteristics of participants. The studies recruited pregnant women from prenatal care facilities who had periodontitis (14 studies) or gingivitis (1 study).The two main comparisons were: periodontal treatment versus no treatment during pregnancy and periodontal treatment versus alternative periodontal treatment. The head-to-head comparison between periodontal treatments assessed a more intensive treatment versus a less intensive one.Eleven studies compared periodontal treatment with no treatment during pregnancy. The meta-analysis shows no clear difference in preterm birth < 37 weeks (RR 0.87, 95% CI 0.70 to 1.10; 5671 participants; 11 studies; low-quality evidence) between periodontal treatment and no treatment. There is low-quality evidence that periodontal treatment may reduce low birth weight < 2500 g (9.70% with periodontal treatment versus 12.60% without treatment; RR 0.67, 95% CI 0.48 to 0.95; 3470 participants; 7 studies).It is unclear whether periodontal treatment leads to a difference in preterm birth < 35 weeks (RR 1.19, 95% CI 0.81 to 1.76; 2557 participants; 2 studies; ) and < 32 weeks (RR 1.35, 95% CI 0.78 to 2.32; 2755 participants; 3 studies), low birth weight < 1500 g (RR 0.80, 95% CI 0.38 to 1.70; 2550 participants; 2 studies), perinatal mortality (including fetal and neonatal deaths up to the first 28 days after birth) (RR 0.85, 95% CI 0.51 to 1.43; 5320 participants; 7 studies; very low-quality evidence), and pre-eclampsia (RR 1.10, 95% CI 0.74 to 1.62; 2946 participants; 3 studies; very low-quality evidence). There is no evidence of a difference in small for gestational age (RR 0.97, 95% CI 0.81 to 1.16; 3610 participants; 3 studies; low-quality evidence) when periodontal treatment is compared with no treatment.Four studies compared periodontal treatment with alternative periodontal treatment. Data pooling was not possible due to clinical heterogeneity. The outcomes reported were preterm birth < 37 weeks, preterm birth < 35 weeks, birth weight < 2500 g, birth weight < 1500 g and perinatal mortality (very low-quality evidence). It is unclear whether there is a difference in < 37 weeks, preterm birth < 35 weeks, birth weight < 2500 g, birth weight < 1500 g and perinatal mortality when different periodontal treatments are compared because the quality of evidence is very low.Maternal mortality and adverse effects of the intervention did not occur in any of the studies that reported on either of the outcomes. It is not clear if periodontal treatment during pregnancy has an impact on preterm birth (low-quality evidence). There is low-quality evidence that periodontal treatment may reduce low birth weight (< 2500 g), however, our confidence in the effect estimate is limited. There is insufficient evidence to determine which periodontal treatment is better in preventing adverse obstetric outcomes. Future research should aim to report periodontal outcomes alongside obstetric outcomes.

The objectives of the study were to (1) investigate the relationship between breast-feeding initiation and duration and patterns of perinatal depressive symptoms and (2) identify the sociodemographic correlates of such initiation and duration. A sample of 2365 women in their second and third trimesters and 6 weeks postdelivery was recruited via systematic sampling from 6 regional public hospitals in Hong Kong. The women were identified as having perinatal depressive symptoms, using the Edinburgh Postnatal Depression Scale. Their sociodemographic variables were investigated using the empirical evidence. A total of 285 (47.66%) of the participants were found to have initiated breast-feeding, of whom 222 had breast-fed for more than 3 weeks. Logistic regression analysis revealed a monthly family income less than HK$5000 to be significantly associated with breast-feeding initiation and that housewives or part-time workers with antenatal depressive symptoms at 32 weeks of gestation were significantly more likely to breast-feed for longer duration. These findings help explicate breast-feeding practices among Chinese women and indicate that effective breast-feeding promotion should consider sociodemographic correlates and perinatal depressive symptoms. The study's limitations and implications are discussed.

Perinatal care advances emerging over the past twenty years have helped to diminish the mortality and severe neurological morbidity of extremely and very preterm neonates (e.g., cystic Periventricular Leukomalacia [c-PVL] and Germinal Matrix Hemorrhage - Intraventricular Hemorrhage [GMH-IVH grade 3-4/4]; 22 to < 32 weeks of gestational age, GA). However, motor and/or cognitive disabilities associated with mild-to-moderate white and gray matter injury are frequently present in this population (e.g., non-cystic Periventricular Leukomalacia [non-cystic PVL], neuronal-axonal injury and GMH-IVH grade 1-2/4). Brain research studies using magnetic resonance imaging (MRI) report that 50% to 80% of extremely and very preterm neonates have diffuse white matter abnormalities (WMA) which correspond to only the minimum grade of severity. Nevertheless, mild-to-moderate diffuse WMA has also been associated with significant affectations of motor and cognitive activities. Due to increased neonatal survival and the intrinsic characteristics of diffuse WMA, there is a growing need to study the brain of the premature infant using non-invasive neuroimaging techniques sensitive to microscopic and/or diffuse lesions. This emerging need has led the scientific community to try to bridge the gap between concepts or ideas from different methodologies and approaches; for instance, neuropathology, neuroimaging and clinical findings. This is evident from the combination of intense pre-clinical and clinicopathologic research along with neonatal neurology and quantitative neuroimaging research. In the following review, we explore literature relating the most frequently observed neuropathological patterns with the recent neuroimaging findings in preterm newborns and infants with perinatal brain injury. Specifically, we focus our discussions on the use of neuroimaging to aid diagnosis, measure morphometric brain damage, and track long-term neurodevelopmental outcomes.

About 0.75 million neonates die every year in India, the highest for any country in the world. The neonatal mortality rate (NMR) declined from 52 per 1000 live births in 1990 to 28 per 1000 live births in 2013, but the rate of decline has been slow and lags behind that of infant and under-five child mortality rates. The slower decline has led to increasing contribution of neonatal mortality to infant and under-five mortality. Among neonatal deaths, the rate of decline in early neonatal mortality rate (ENMR) is much lower than that of late NMR. The high level and slow decline in early NMR are also reflected in a high and stagnant perinatal mortality rate. The rate of decline in NMR, and to an extent ENMR, has accelerated with the introduction of National Rural Health Mission in mid-2005. Almost all states have witnessed this phenomenon, but there is still a huge disparity in NMR between and even within the states. The disparity is further compounded by rural-urban, poor-rich and gender differentials. There is an interplay of different demographic, educational, socioeconomic, biological and care-seeking factors, which are responsible for the differentials and the high burden of neonatal mortality. Addressing inequity in India is an important cross-cutting action that will reduce newborn mortality.

The pattern and global burden of disease has evolved considerably over the last two decades, from primarily communicable, maternal, and perinatal causes to non-communicable disease (NCD). Cardiovascular disease (CVD) has become the single most important and largest cause of NCD deaths worldwide at over 50%. The World Health Organisation (WHO) estimates that 17.6 million people died of CVD worldwide in 2012. Proportionally, this accounts for an estimated 31.43% of global mortality, with ischaemic heart disease (IHD) accounting for approximately 7.4 million deaths, 13.2% of the total. IHD was also the greatest single cause of death in 2000, accounting for an estimated 6.0 million deaths. The global burden of CVD falls, principally, on the low and middle-income (LMI) countries, accounting for over 80% of CVD deaths. Individual populations face differing challenges and each population has unique health burdens, however, CVD remains one of the greatest health challenges both nationally and worldwide.

In the past decade there have been an increasing number of scientific studies describing possible effects of air pollution on perinatal health. These papers have mostly focused on commonly monitored air pollutants, primarily ozone (O(3)), particulate matter (PM), sulfur dioxide (SO(2)), carbon monoxide (CO), and nitrogen dioxide (NO(2)), and various indices of perinatal health, including fetal growth, pregnancy duration, and infant mortality. While most published studies have found some marker of air pollution related to some types of perinatal outcomes, variability exists in the nature of the pollutants and outcomes associated. Synthesis of the findings has been difficult for various reasons, including differences in study design and analysis. A workshop was held in September 2007 to discuss methodological differences in the published studies as a basis for understanding differences in study findings and to identify priorities for future research, including novel approaches for existing data. Four broad topic areas were considered: confounding and effect modification, spatial and temporal exposure variations, vulnerable windows of exposure, and multiple pollutants. Here we present a synopsis of the methodological issues and challenges in each area and make recommendations for future study. Two key recommendations include: (1) parallel analyses of existing data sets using a standardized methodological approach to disentangle true differences in associations from methodological differences among studies; and (2) identification of animal studies to inform important mechanistic research gaps. This work is of critical public health importance because of widespread exposure and because perinatal outcomes are important markers of future child and adult health.

Globally, eHealth has attracted considerable attention as a means of supporting maternal and perinatal health care. This article describes best practices, gains and challenges of implementing eHealth for maternal and perinatal health care in extremely remote and rural Tanzania. Teleconsultation for obstetric emergency care, audio teleconferences and online eLearning systems were installed in ten upgraded rural health centres, four rural district hospitals and one regional hospital in Tanzania. Uptake of teleconsultation and teleconference platforms were evaluated retrospectively. A cross sectional descriptive study design was applied to assess performance and adoption of eLearning. In 2015 a total of 38 teleconsultations were attended by consultant obstetricians and 33 teleconferences were conducted and attended by 40 health care providers from 14 facilities. A total of 240 clinical cases mainly caesarean sections (CS), maternal and perinatal morbidities and mortalities were discussed and recommendations for improvement were provided. Four modules were hosted and 43 care providers were registered on the eLearning system. For a period of 18-21 months total views on the site, weekly conference forum, chatroom and learning resources ranged between 106 and 1,438. Completion of learning modules, acknowledgment of having acquired and utilized new knowledge and skills in clinical practice were reported in 43-89% of 20 interviewed health care providers. Competencies in using the eLearning system were demonstrated in 62% of the targeted users. E-Health presents an opportunity for improving maternal health care in underserved remote areas in low-resource settings by broadening knowledge and skills, and by connecting frontline care providers with consultants for emergency teleconsultations.

Background Perinatal hypoxia is one of the leading causes of perinatal mortality in developing countries. Both apgar score and arterial blood pH predict the neonatal mortality in asphyxia. Apgar score alone does not predict neurologic outcome and as it is influenced by various factors. This study was conducted to evaluate the utility and sensitivity of urinary uric acid to creatinine ratio (UA/Cr ratio) in asphyxia diagnosis, compared to invasive Arterial Blood Gas (ABG) analysis. Aim To assess the urinary uric acid/creatinine ratio as an additional marker for perinatal asphyxia compared with ABG analysis in apgar score monitoring. Materials and Methods The present case control study was conducted at a teaching hospital in Central Gujarat. Data of 40 healthy newborns and 40 asphyxiated newborns were collected. In absence of regional estimates, a sample of size 39 was required to attain a power of 80% at 5% alpha (type I error) considering a moderate effect size of 0.65. (UA/Cr) ratio was measured from the spot urine sample collected during 24-72 hours of birth. Statistical analysis was performed by Independent t-test, Pearson’s correlation coefficient (r) and Receiver Operating Characteristic (ROC) plots. Results The mean (UA/Cr ratio) (2.75±0.18 vs 1.78±0.23) is significantly higher in asphyxiated group than in the control group (p<0.0001). Urinary UA/Cr ratio had negative correlation with blood pH (r= -0.27, p=0.18), which was not significant (p>0.05). Urinary UA/Cr ratio with criterion of >2.3 had 100% sensitivity, 100% specificity with AUC of 1 (p<0.0001) had a better predictive value. Conclusions Apgar score is usually reduced in neonates with congenital anomalies and premature neonates. Hence, it is preferable that the clinical diagnosis of asphyxia by apgar scores be supported by other investigations so that early decision can be taken about the level of care the baby needs. pH, lactates and base deficits change with establishment of respiration following resuscitation. However, pH, lactate, base deficit estimations are invasive and need rapid estimations. Non-invasive urinary UA/Cr ratio may be an answer to these issues as it easy, economical and equally efficient.

2014-01-01

Objective To study whether neonatal and infant mortality, after adjustments for differences in case mix, were independent of the type of hospital in which the delivery was carried out. Data The Medical Birth Registry of Norway provided detailed medical information for all births in Norway. Study Design Hospitals were classified into two groups: local hospitals/maternity clinics versus central/regional hospitals. Outcomes were neonatal and infant mortality. The data were analyzed using propensity score weighting to make adjustments for differences in case mix between the two groups of hospitals. This analysis was supplemented with analyses of 13 local hospitals that were closed. Using a difference-in-difference approach, the effects that these closures had on neonatal and infant mortality were estimated. Principal Finding Neonatal and infant mortality were not affected by the type of hospital where the delivery took place. Conclusion A regionalized maternity service does not lead to increased neonatal and infant mortality. This is mainly because high-risk deliveries were identified well in advance of the birth, and referred to a larger hospital with sufficient perinatal resources to deal with these deliveries.

The objective of this study was to test the validity of the pragmatic criteria of the definitions of neonatal near miss, extending them throughout the infant period, and to estimate the indicators of perinatal care in public maternity hospitals. A cohort of live births from six maternity hospitals in the municipalities of São Paulo, Niterói, and Rio de Janeiro, Brazil, was carried out in 2011. We carried out interviews and checked prenatal cards and medical records. We compared the pragmatic criteria (birth weight, gestational age, and 5' Apgar score) of the definitions of near miss of Pileggi et al., Pileggi-Castro et al., Souza et al., and Silva et al. We calculated sensitivity, specificity (gold standard: infant mortality), percentage of deaths among newborns with life-threatening conditions, and rates of near miss, mortality, and severe outcomes per 1,000 live births. A total 7,315 newborns were analyzed (completeness of information > 99%). The sensitivity of the definition of Pileggi-Castro et al. was higher, resulting in a higher number of cases of near miss, Souza et al. presented lower value, and Pileggi et al. and de Silva et al. presented intermediate values. There is an increase in sensitivity when the period goes from 0-6 to 0-27 days, and there is a decrease when it goes to 0-364 days. Specificities were high (≥ 97%) and above sensitivities (54% to 77%). One maternity hospital in São Paulo and one in Niterói presented, respectively, the lowest and highest rates of infant mortality, near miss, and frequency of births with life-threatening conditions, regardless of the definition. The definitions of near miss based exclusively on pragmatic criteria are valid and can be used for monitoring purposes. Based on the perinatal literature, the cutoff points adopted by Silva et al. were more appropriate. Periodic studies could apply a more complete definition, incorporating clinical, laboratory, and management criteria, including congenital anomalies predictive of infant mortality.

Objectives The maternal near-miss case review (NMCR) has been promoted by WHO as an approach to improve quality of care (QoC) at facility level. This systematic review synthesises evidence on the effectiveness of the NMCR on QoC and maternal and perinatal health outcomes in low-income and middle-income countries (LMICs). Methods Studies were searched for in six electronic databases (MEDLINE, Index Medicus, Web of Science, the Cochrane library, Embase, LILACS), with no language restrictions. Two authors independently screened papers and selected them for inclusion and independently extracted data. Maternal mortality was the primary outcome. Secondary outcomes included any outcome informing on any of the six dimensions of QoC: efficacy, safety, efficiency, equity, accessibility and timely care, acceptability and patient-centred care. Results Out of 24 822 papers retrieved, 17 studies from 11 countries were included. Maternal mortality measured before and after the implementation of the NMCR cycle significantly decreased (OR 0.77, 95% CI 0.61 to 0.98, eight studies, 55 573 043 women; I2=39%). A statistically significant reduction in the incidence of uterine rupture, postpartum haemorrhage and maternal sepsis was observed in three out of six studies. Ten studies reporting on maternal care process all showed some significant improvement when measured against predefined standards. All studies reported that the NMCR resulted in some amelioration of the facility structure (physical structure, staffing, equipment, training, organisation of care). Newborn outcomes were overall poorly reported; four studies showed no significant difference in perinatal mortality. Patient satisfaction and equity were also poorly reported. Conclusions Policy makers may consider implementing the maternal NMCR cycle approach among strategies aiming at improving QoC and reducing maternal mortality and morbidity in LMIC. Future studies should better document the effectiveness of the NMCR cycle particularly on outcomes reflecting patient-centred care and cost-effectiveness. PMID:29674368

2016-10-01

Maternal depression, a non-psychotic depressive episode of mild to major severity, is one of the major contributors of pregnancy-related morbidity and mortality. Maternal depression (antepartum or post partum) has been linked to negative health-related behaviours and adverse outcomes, including psychological and developmental disturbances in infants, children, and adolescents. Despite its enormous burden, maternal depression in low-income and middle-income countries remains under-recognised and undertreated. In this Series paper, we systematically review studies that focus on the epidemiology of perinatal depression (ie, during antepartum and post-partum periods) among women residing in low-income and middle-income countries. We also summarise evidence for the association of perinatal depression with infant and childhood outcomes. This review is intended to summarise findings from the existing literature, identify important knowledge gaps, and set the research agenda for creating new generalisable knowledge pertinent to increasing our understanding of the prevalence, determinants, and infant and childhood health outcomes associated with perinatal depression. This review is also intended to set the stage for subsequent work aimed at reinforcing and accelerating investments toward providing services to manage maternal depression in low-income and middle-income countries.

My approach to performing a perinatal or neonatal autopsy

PubMed Central

Wainwright, H C

2006-01-01

An opportunity to determine the cause of death, factors that may have a role in it, and the extent and cause of malformations is provided by perinatal autopsy. The family may be assisted in finding closure after the death of their infant by the information obtained. Insight into classifying infants appearing normal into one of three groups, small, appropriate and large for gestational age, has been provided, as each group tends to have specific causes of death. In infants with congenital anomalies, patterns of malformation may lead us to the diagnosis. An accurate diagnosis is required to provide counselling for a subsequent pregnancy. PMID:16803946

To examine whether community health centers (CHCs) reduce racial/ethnic disparities in perinatal care and birth outcomes, and to identify CHC characteristics associated with better outcomes. Despite great national wealth, the U.S. continues to rank poorly relative to other industrialized nations on infant mortality and other birth outcomes, and with wide inequities by race/ethnicity. Disparities in primary care (including perinatal care) may contribute to disparities in birth outcomes, which may be addressed by CHCs that provide safety-net medical services to vulnerable populations. Data are from annual Uniform Data System reports submitted to the Bureau of Primary Health Care over six years (1996-2001) by about 700 CHCs each year. Across all years, about 60% of CHC mothers received first-trimester prenatal care and more than 70% received postpartum and newborn care. In 2001, Asian mothers were the most likely to receive both postpartum and newborn care (81.7% and 80.3%), followed by Hispanics (75.0% and 76.3%), blacks (70.8% and 69.9%), and whites (70.7% and 66.7%). In 2001, blacks had higher rates of low birth weight (LBW) babies (10.4%), but the disparity in rates for blacks and whites was smaller in CHCs (3.3 percentage points) compared to national disparities for low-socioeconomic status mothers (5.8 percentage points) and the total population (6.2 percentage points). In CHCs, greater perinatal care capacity was associated with higher rates of first-trimester prenatal care, which was associated with a lower LBW rate. Racial/ethnic disparities in certain prenatal services and birth outcomes may be lower in CHCs compared to the general population, despite serving higher-risk groups. Within CHCs, increasing first-trimester prenatal care use through perinatal care capacity may lead to further improvement in birth outcomes for the underserved.

Objective To describe facility-based decision-making for women with one prior cesarean delivery (CD) in a resource-limited setting and to characterize maternal and perinatal outcomes in these groups. Methods One year retrospective study of women with one prior CD delivering at Korle-Bu Teaching Hospital (KBTH), Ghana. Women were categorized into three groups based on initial plan of management on admission [trial of labor after cesarean (TOLAC), emergency repeat CD (EMCD) or non-emergent repeat CD (RCD)]. Characteristics and outcomes across these groups were then compared. Results During the study period, 1247 women with one prior CD delivered at KBTH, of which 377 (30.2%) were triaged to RCD, 439 (35.2%) to EMCD and 431 (34.6%) to TOLAC. Twelve uterine ruptures and no maternal deaths occurred. Perinatal mortality was 4.2% (n = 52). Compared to the RCD group, the TOLAC group had a lower risk for maternal adverse events (aOR 0.3, 95% CI 0.1-1.0; p = 0.04) and non-significant higher risk of perinatal adverse events (aOR 1.6, 95% CI 0.7-3.3; p = 0.25). Compared to women triaged to RCD, the EMCD group had a non-significant increase in risk of maternal adverse events (aOR 1.6, 95% CI 0.8-3.5; p = 0.2) and a significantly higher rate of perinatal adverse events (aOR 2.4, 95% CI 1.2-4.9; p = 0.01). Conclusions for Practice Women triaged to EMCD at admission are different when compared to women allowed a TOLAC or offered a non-emergent RCD. These women bear increased rates of adverse outcomes and should be considered as a separate group for analysis in future studies conducted in similar settings.

We investigated associations between maternal characteristics, access to care, and obstetrical complications including near miss status on admission or during hospitalization on perinatal outcomes among Indonesian singletons. We prospectively collected data on inborn singletons at two hospitals in East Java. Data included socio-demographics, reproductive, obstetric and neonatal variables. Reduced multivariable models were constructed. Outcomes of interest included low and very low birthweight (LBW/VLBW), asphyxia and death. Referral from a care facility was associated with a reduced risk of LBW and VLBW [AOR = 0.28, 95% CI = 0.11-0.69, AOR = 0.18, 95% CI = 0.04-0.75, respectively], stillbirth [AOR = 0.41, 95% CI = 0.18-0.95], and neonatal death [AOR = 0.2, 95% CI = 0.05-0.81]. Mothers age <20 years increased the risk of VLBW [AOR = 6.39, 95% CI = 1.82-22.35] and neonatal death [AOR = 4.10, 95% CI = 1.29-13.02]. Malpresentation on admission increased the risk of asphyxia [AOR = 4.65, 95% CI = 2.23-9.70], stillbirth [AOR = 3.96, 95% CI = 1.41-11.15], and perinatal death [AOR = 3.89 95% CI = 1.42-10.64], as did poor prenatal care (PNC) [AOR = 11.67, 95%CI = 2.71-16.62]. Near-miss on admission increased the risk of neonatal [AOR = 11.67, 95% CI = 2.08-65.65] and perinatal death [AOR = 13.08 95% CI = 3.77-45.37]. Mothers in labor should be encouraged to seek care early and taught to identify early danger signs. Adequate PNC significantly reduced perinatal deaths. Improved hospital management of malpresentation may significantly reduce perinatal morbidity and mortality. The importance of hospital-based prospective studies helps evaluate specific areas of need in training of obstetrical care providers.

As extremely preterm infant mortality rates have decreased, concerns regarding resource utilization have intensified. Accurate models to predict time to hospital discharge could aid in resource planning, family counseling, and perhaps stimulate quality improvement initiatives. Objectives For infants <27 weeks estimated gestational age (EGA), to develop, validate and compare several models to predict time to hospital discharge based on time-dependent covariates, and based on the presence of 5 key risk factors as predictors. Patients and Methods This was a retrospective analysis of infants <27 weeks EGA, born 7/2002-12/2005 and surviving to discharge from a NICHD Neonatal Research Network site. Time to discharge was modeled as continuous (postmenstrual age at discharge, PMAD), and categorical variables (“Early” and “Late” discharge). Three linear and logistic regression models with time-dependent covariate inclusion were developed (perinatal factors only, perinatal+early neonatal factors, perinatal+early+later factors). Models for Early and Late discharge using the cumulative presence of 5 key risk factors as predictors were also evaluated. Predictive capabilities were compared using coefficient of determination (R2) for linear models, and AUC of ROC curve for logistic models. Results Data from 2254 infants were included. Prediction of PMAD was poor, with only 38% of variation explained by linear models. However, models incorporating later clinical characteristics were more accurate in predicting “Early” or “Late” discharge (full models: AUC 0.76-0.83 vs. perinatal factor models: AUC 0.56-0.69). In simplified key risk factors models, predicted probabilities for Early and Late discharge compared favorably with observed rates. Furthermore, the AUC (0.75-0.77) were similar to those of models including the full factor set. Conclusions Prediction of Early or Late discharge is poor if only perinatal factors are considered, but improves substantially with knowledge of later-occurring morbidities. Prediction using a few key risk factors is comparable to full models, and may offer a clinically applicable strategy. PMID:20008430

Emergency peripartum hysterectomy (EPH) is associated with significant morbidity and mortality worldwide. The purpose of our paper was to determine the incidence, morbidity, and mortality of EPH done at our institution; the largest tertiary care government hospital in the city of Quetta, Pakistan. During the study period there were 12,642 deliveries, out of which 46 women had undergone an EPH, translating into an incidence of ∼4 per 1,000 births. Disturbingly, 82.6% of these patients had received no antenatal care prior to their presentation. There were 4 (8.7%) maternal deaths and 31 (67.4%) perinatal deaths. The commonest indication noted was uterine rupture in 21 (45.7%) cases. Lack of antenatal care is indeed a modifiable factor that needs to be addressed to help reduce maternal and fetal morbidity/mortality not only from emergency hysterectomies but also from all other preventable causes.

To analyze the demographic characteristics and the death causes of the residents in Anhui province, and provide evidence for the disease prevention and control. Using descriptive epidemiological analysis, the demographic characteristics and death data of the national disease surveillance points (DSPs) in Anhui province in 2013 were analyed by areas. The aging of the population was observed in all the areas in Anhui, which was most obvious in Jianghuai, followed by Wannan and Huaibei. The overall mortality was 627.10/100 000. The mortalities of diseases varied with sex, area and age. Among the 3 areas, the overall mortality, chronic disease mortality and injury mortality were highest in Huaibei and lowest in Wannan. The area specific difference in mortality of infectious diseases was small. Regardless of areas or the types of diseases, the mortality was higher in males than in females. Deaths caused by diseases with unknown origins were common in residents aged >65 years. The mortality of chronic diseases was higher in residents aged >45 years, especially in those aged 65-84 years. The mortality of injuries was higher in age groups >15 years and >45 years. The mortality of infectious diseases peaked at both young age group and old age group. The top five death causes were cerebrovascular diseases, malignant tumors, heart diseases, respiratory diseases and injuries. Regardless of sex or area, the major death causes were similar, but the ranks were slightly different. The major death causes varied in different age groups, but they were similar in same age group in different areas. The major death causes were diseases originated in perinatal period, and congenital malformations, deformations and chromosomal abnormalities in children aged <1 year. The major death causes in children aged 1-14 years were injuries, diseases originated in perinatal period, congenital malformations, deformations and chromosomal abnormalities. Injuries and malignant tumors were the first and second death causes in residents aged 15-44 years. Malignant tumors, injuries, cerebrovascular diseases and heart diseases were the major death causes in residents aged 45-64 years. The major death causes were cerebrovascular diseases, malignant tumors, heart diseases and respiratory diseases in residents aged 65-84 years and heart diseases, cerebrovascular diseases, respiratory diseases and malign tumors in residents aged≥85 years. The major death causes in residents in Anhui province were cerebrovascular diseases, malignant tumors and injuries. Close attention should be paid to the prevention and control of cerebrovascular diseases, malignant tumors and heart diseases in age group≥45 years. It is necessary to strengthen the prevention and control of injuries in age group 15-44 years. Huaibei is a key area of disease prevention and control in Anhui, especially chronic disease and injury preventions.

Are Pregnant and Postpartum Women Interested in Health-Related Apps? Implications for the Prevention of Perinatal Depression.

2016-06-01

Recent studies have shown that women are more likely than men to use the Internet to seek health information and that the use of technology is common among perinatal women. Access to the Internet is growing through the global use of mobile phones and apps, in both developed and less developed countries. This pattern is particularly relevant for clinicians and researchers who are interested in the use of technologies to disseminate perinatal depression interventions. In a cross-sectional anonymous online survey for English and Spanish-speaking perinatal women, 509 pregnant (77.6 percent) and postpartum (22.4 percent) women provided demographic and Information and Communication Technologies data. Results indicated that the single device with greatest access was the mobile phone (47.5 percent). The majority of the sample had Internet access through mobile phones, computers, or both. Significant differences in socioeconomic status were found for Internet seeking behavior of health-related information and downloading apps between those with and without Internet access. Ninety percent of respondents (n = 267) searched for health-related information and 72.3 percent had downloaded any kind of app. More than half of respondents (57 percent, n = 188) downloaded a health-related app and 26.9 percent reported having paid for the apps. This study shows preliminary evidence to suggest the need to design, develop, and test apps that aim to disseminate prevention programs for perinatal depression.

Objective In the context of rapid changes regarding practices related to delivery in Africa, we assessed maternal and perinatal adverse outcomes associated with the mode of delivery in 41 referral hospitals of Mali and Senegal. Study Design Cross-sectional survey nested in a randomised cluster trial (1/10/2007–1/10/2008). The associations between intended mode of delivery and (i) in-hospital maternal mortality, (ii) maternal morbidity (transfusion or hysterectomy), (iii) stillbirth or neonatal death before Day 1 and (iv) neonatal death between 24 hours after birth and hospital discharge were examined. We excluded women with immediate life threatening maternal or fetal complication to avoid indication bias. The analyses were performed using hierarchical logistic mixed models with random intercept and were adjusted for women's, newborn's and hospitals' characteristics. Results Among the 78,166 included women, 2.2% had a pre-labor cesarean section (CS) and 97.8% had a trial of labor. Among women with a trial of labor, 87.5% delivered vaginally and 12.5% had intrapartum CS. Pre-labor CS was associated with a marked reduction in the risk of stillbirth or neonatal death before Day 1 as compared with trial of labor (OR = 0.2 [0.16–0.36]), though we did not show that maternal mortality (OR = 0.3 [0.07–1.32]) and neonatal mortality after Day 1 (OR = 1.3 (0.66–2.72]) differed significantly between groups. Among women with trial of labor, intrapartum CS and operative vaginal delivery were associated with higher risks of maternal mortality and morbidity, and neonatal mortality after Day 1, as compared with spontaneous vaginal delivery. Conclusions In referral hospitals of Mali and Senegal, pre-labor CS is a safe procedure although intrapartum CS and operative vaginal delivery are associated with increased risks in mothers and infants. Further research is needed to determine what aspects of obstetric care contribute to a delay in the provision of intrapartum interventions so that practices may be made safer when they are needed.

2015-08-01

Evidence-based interventions and strategies are needed to improve child survival in countries with a high burden of neonatal and child mortality. An overview of systematic reviews can focus implementation on the most effective ways to increase child survival. In this overview we included published Cochrane and other systematic reviews of experimental and observational studies on antenatal, childbirth, postnatal and child health interventions aiming to prevent perinatal/neonatal and child mortality using the WHO list of essential interventions. We assessed the methodological quality of the reviews using the AMSTAR criteria and assessed the quality of the outcomes using the GRADE approach. Based on the findings from GRADE criteria, interventions were summarized as effective, promising or ineffective. The overview identified 148 Cochrane and other systematic reviews on 61 reproductive, maternal, newborn and child health interventions. Of these, only 57 reviews reported mortality outcomes. Using the GRADE approach, antenatal corticosteroids for preventing neonatal respiratory distress syndrome in preterm infants; early initiation of breastfeeding; hygienic cord care; kangaroo care for preterm infants; provision and promotion of use of insecticide treated bed nets (ITNs) for children; and vitamin A supplementation for infants from six months of age, were identified as clearly effective interventions for reducing neonatal, infant or child mortality. Antenatal care, tetanus immunization in pregnancy, prophylactic antimalarials during pregnancy, induction of labour for prolonged pregnancy, case management of neonatal sepsis, meningitis and pneumonia, prophylactic and therapeutic use of surfactant, continuous positive airway pressure for neonatal resuscitation, case management of childhood malaria and pneumonia, vitamin A as part of treatment for measles associated pneumonia for children above 6 months, and home visits across the continuum of care, were identified as promising interventions for reducing neonatal, infant, child or perinatal mortality. Comprehensive adoption of the above six effective and 11 promising interventions can improve neonatal and child survival around the world. Choice of intervention and degree of implementation currently depends on resources available and policies in individual countries and geographical settings.

Background Facilitation of local women's groups may reportedly reduce neonatal mortality. It is not known whether facilitation of groups composed of local health care staff and politicians can improve perinatal outcomes. We hypothesised that facilitation of local stakeholder groups would reduce neonatal mortality (primary outcome) and improve maternal, delivery, and newborn care indicators (secondary outcomes) in Quang Ninh province, Vietnam. Methods and Findings In a cluster-randomized design 44 communes were allocated to intervention and 46 to control. Laywomen facilitated monthly meetings during 3 years in groups composed of health care staff and key persons in the communes. A problem-solving approach was employed. Births and neonatal deaths were monitored, and interviews were performed in households of neonatal deaths and of randomly selected surviving infants. A latent period before effect is expected in this type of intervention, but this timeframe was not pre-specified. Neonatal mortality rate (NMR) from July 2008 to June 2011 was 16.5/1,000 (195 deaths per 11,818 live births) in the intervention communes and 18.4/1,000 (194 per 10,559 live births) in control communes (adjusted odds ratio [OR] 0.96 [95% CI 0.73–1.25]). There was a significant downward time trend of NMR in intervention communes (p = 0.003) but not in control communes (p = 0.184). No significant difference in NMR was observed during the first two years (July 2008 to June 2010) while the third year (July 2010 to June 2011) had significantly lower NMR in intervention arm: adjusted OR 0.51 (95% CI 0.30–0.89). Women in intervention communes more frequently attended antenatal care (adjusted OR 2.27 [95% CI 1.07–4.8]). Conclusions A randomized facilitation intervention with local stakeholder groups composed of primary care staff and local politicians working for three years with a perinatal problem-solving approach resulted in increased attendance to antenatal care and reduced neonatal mortality after a latent period.

Objective: The aim of this study was to investigate trajectories of sleep quality and associations with mood in the perinatal period. Although it is commonly accepted that subjective sleep quality declines during pregnancy and the transition to parenthood, some women may follow qualitatively distinct trajectories. Design, Setting, and Participants: Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). Data were collected from 293 women at four time points: during early pregnancy, at Time 1 (T1; < 22 w gestational age [GA]; late pregnancy, at Time 2 (T2; 32 w GA); during the postnatal period at Time 3 (T3; 3 mo postpartum); and Time 4 (T4; 6 mo postpartum). A group-based semiparametric mixture model was used to estimate patterns of sleep quality throughout the perinatal period. Results: Four trajectory groups were identified, including patterns defined by high sleep quality throughout (21.5%), mild decrease in sleep quality (59.5%), significant decrease in sleep quality (12.3%) and a group with poor sleep quality throughout (6.7%). Women who had the worst sleep quality at Time 1 and those who experienced significant increases in sleep problems throughout pregnancy were also the groups who reported the highest levels of anxiety and depressive symptoms in early pregnancy and the lowest levels of social support. After controlling for covariates, the groups with worst subjective sleep quality during pregnancy were also the most likely to experience high symptoms of depression in the postpartum period. Conclusions: Most of the women in our sample reported mild sleep disturbances through the perinatal period. A subgroup of women reported a significant decline in sleep quality from early to late pregnancy and another reported poor subjective sleep quality throughout pregnancy; these groups had the greatest risk of experiencing high symptoms of depression in the postpartum period.

to measure the magnitude of eclampsia and its maternal and perinatal outcome. A 5 years retrospective descriptive study was conducted on 216 eclamptic cases diagnosed, admitted and managed from October 1994 to September 1999 in the two teaching hospitals of Addis Ababa; namely Tikur Anbessa and St Paul's Hospitals. There were 257 mothers with eclampsia treated in the given period and 35741 deliveries making the incidence of eclampsia 7.1/1000 deliveries. Eighty-four women (38.9%) had any antenatal care, 157 (72.7%) were nulli-parous and 69 (31.8%) were aged below 20. Convulsion occurred ante-partum in 133 (61.6%), intrapartum in 49 (22.7%) and postpartum in 34 (15.7%) mothers. The most frequently sited symptoms before convulsion include headache in 83.8%, visual disturbance in 41.6% and epigastric pain in 38.4% of the cases. Ninety nine (45.8%) women were delivered by cesarean section making the cesarean section rate among eclamptic mothers significantly higher than the rate among the general population, which was 16.6% at the same period. (P = 0.0001). The multiple pregnancy rate was 5.7%, which was significantly higher than the rate among the general population of 1.5% at the same time. Seventy-four mothers had repeated convulsion after admission to the hospitals and initiation of the standard treatment. Twenty-eight mothers with eclampsia died making the case fatality rate 13%. Seven mothers (3.2%) died before delivery. Forty-four Stillbirths and twenty-five early neonatal deaths occurred making the perinatal mortality rate 312.2/1000 deliveries. Eclampsia is a common complication still associated with high level of maternal and perinatal mortality as well as morbidity. ANC coverage should be strengthened to detect preclampsia, and prevent eclampsia. Management in the hospital should be optimized to prevent recurrent convulsions and complications after admission.

In chick embryos, gas exchange takes place via the chorioallantoic membrane (CAM) and the lungs at approximately 1 day prior to hatching. The present study was designed to elucidate the development of respiratory rhythms in the chick embryo during the whole pipping (perinatal) period with a condenser-microphone measuring system. The microphone was hermetically attached on the eggshell over the air cell on day 18 of incubation. It first detected a cardiogenic signal (i.e. acoustocardiogram), and then beak clapping and breathing signals (acoustorespirogram, ARG). The first signals of lung ventilation appeared intermittently and irregularly approximately once per 5 s among the clapping signals after the embryo penetrated its beak into the air cell (internal pipping, IP). The respiratory rhythm then developed irregularly, with a subsequent more regular rate. The envelope pattern of breathing from the onset of IP through external pipping (EP) to hatching was constructed by a specially devised procedure, which eliminated external and internal noises. The envelope patterns indicated that the IP, EP and whole perinatal periods of 10 embryos were 14.1+/-6.4 (S.D.), 13.6+/-4.0 and 27.6+/-5.4 h, respectively. In addition, they also indicated the period of embryonic hatching activity (i.e. climax) which was 48+/-19 min. The development of respiratory rhythm was also shown by the instantaneous respiratory rate (IRR) which was designated as an inverse value of two adjacent ARG waves.

The objective was to assess trends in Inuit, First Nations and non-Aboriginal birth outcomes in the rural and northern regions of Quebec. In a birth cohort-based study of all births to residents of rural and northern Quebec from 1991 through 2000 (n = 177,193), we analyzed birth outcomes and infant mortality for births classified by maternal mother tongue (Inuit, First Nations or non-Aboriginal) and by community type (predominantly First Nations, Inuit or non-Aboriginal). From 1991-1995 to 1996-2000, there was a trend of increasing rates of preterm birth for all 6 study groups. In all rural and northern areas, low birth weight rates increased significantly only for the Inuit mother tongue group [RR1.45 (95% CI 1.05-2.01)]. Stillbirth rates showed a non-significant increase for the Inuit mother tongue group [RR1.76 (0.64-4.83)]. Neonatal mortality rates decreased significantly in the predominantly non-Aboriginal communities and in the non-Aboriginal mother tongue group [RR0.78 (0.66-0.92)], and increased non-significantly for the First Nations mother tongue group [RR2.17 (0.71-6.62)]. Perinatal death rates increased for the First Nations mother tongue grouping in northern areas [RR2.19 (0.99-4.85)]. There was a disconcerting rise of some mortality outcomes for births to First Nations and Inuit mother tongue women and to women in predominantly First Nations and Inuit communities, in contrast to some improvements for births to non-Aboriginal mother tongue women and to women in predominantly non-Aboriginal communities in rural or northern Quebec, indicating a need for improving perinatal and neonatal health for Aboriginal populations in rural and northern regions.

Respiratory morbidity in congenital diaphragmatic hernia (CDH) is associated with high mortality and adverse outcome. Accurate prenatal diagnosis is essential for prognosis and potential treatment in utero. The aim was to evaluate the prenatal ultrasound findings in assessing the respiratory prognosis in fetuses with isolated left-sided CDH. We retrospectively analyzed the medical records of 59 prenatally diagnosed left-sided CDH cases managed at a tertiary perinatal center. Survival rate in the study group was 73% (43/59). We found no statistically significant relationship between survival and the presence of polyhydramnios, gestational age at diagnosis, lung-to-head ratio (LHR) and observed/expected LHR (O/E LHR) values, gestational age at birth and birth weight. Intrathoracic liver herniation was a statistically significant parameter adversely affecting survival (37.2% in survivors, 68.8% in non-survivors, p = 0.031) and logistic regression confirmed this relationship. The presence of pneumothorax and severe pulmonary hypertension were significantly associated with mortality (82% non-survivors versus 15% in survivors, p = 0.0001). Intrathoracic liver herniation seems to be a reliable parameter in the prediction of survival and neonatal respiratory morbidity in fetuses with isolated left-sided CDH. In contrast, we found no significant correlation between perinatal outcome and LHR, O/E LHR values, birth weight and gestational age.

One hundred and four patients who delivered after a previous cesarean section, at Hospital de Ginecoobstetricia de Garza García, N.L., from February 1, 1994 to January 31, 1995, were reviewed. The objective for this study was to know materno-fetal morbi-mortality at our hospital. Age, parity weeks of gestation, cause for previous section, delivery culmination, weight and Apgar of products, as well as, materno-fetal morbi-mortality, were analyzed. Average age group was 21 to 30 years with 68.5%. As to parity nulliparae predominated with 48.1%. As to weeks of gestation, the most frequent was 37 to 40 weeks, 85.5%. Previous section indication was: 1. Pelvic presentation, 2. Fetal stress, 3. Cefalo-pelvic disproportion, 4. Premature rupture of membranes, 5. Toxemia. As to deliveries outcome, there was dystocia in 86.5%, by profilactic low forceps application in 81.7%; and mid low in 4.8%. Eutocic delivery, 13.5%. Product weight was 3,000 to 3,500 g, with 51%. Apgar in 94 products was 8 and 9 at one minute. Maternal morbidity was 15.3% being most frequent vaginal tears. There was one case of uterine atonia, and one case of dura mater adverted puncture. There were no uterine dehiscence nor rupture. Perinatal morbidity was 5.6%. There was no perinatal death.

Multinational data on assisted reproduction techniques undertaken in 2014 were collected from 159 institutions in 15 countries in Latin America. Treatments included IVF/ ICSI, FET, OD, PGD and fertility preservation (FP). 41.34% of IVF/ICSI cycles were performed in women aged 35 to 39 years and 23.35% in women aged 40 and older. After removing cases with total freezing, delivery rate per oocyte retrieval was 25.05% for ICSI and 27.41% for IVF. Multiple births included 20.78% twins and 0.92 % triplets and over. In OD, twins reached 28.93% and triplets 1.07 %. Preterm deliveries reached 16.4% in singletons, 55.02% in twins and 76% in triplets. Perinatal mortality in 18,162 births was 23 per 1000 in singletons, 35 per 1000 in twins, and 36 per 1000 in high-order multiples. Elective single embryo transfer (eSET) represented only 2.63 % of fresh transfers, with a delivery rate of 32.15% per transfer. Elective double embryo transfer (eDET) represented 23.74% of transfers, with a delivery rate of 41.03% per transfer. Among babies born during this period 11,373 (62.6%) were singletons; 6,398 (35.2%) twins, and 391 (2.2%), triplets and more. Given the effect of multiple births on prematurity, morbidity and perinatal mortality, reinforcing the existing trend of reducing the number of embryos transferred is mandatory PMID:28837023

Omphalitis and the resulting septicemia contribute to perinatal mortality in several animal species. In foals, the most important causes of omphalitis are Escherichia coli and Streptococcus zooepidemicus. However to date, no information has been published about the role of Clostridium sordellii in these infections. In this paper, we describe 8 cases of perinatal mortality in foals associated with internal umbilical remnant infection by C. sordellii. The foals studied were between 12 and 21 days old at the time of death, and various breeds were represented in the group. Five of the foals were male and 3 were female. The diagnosis was established on the basis of the detection of C. sordellii by 3 methods (culture, fluorescent antibody test, and immunohistochemistry) and on gross and histopathologic findings. All foals had acute peritonitis, and the internal umbilical remnant was thickened by edema, hemorrhage, and fibrosis. A moderate amount of serosanguinous fluid with fibrin strands was present in the pericardial sac and pleural cavity. Histopathologically, the urachus and umbilical arterial walls were thickened by edema and exhibited hemorrhage, fibrin, and leukocytic infiltration. Gram-positive bacterial rods were observed in subepithelial areas of the urachus, the adventicia of umbilical arteries, and interstitium of the internal umbilical remnant. On the basis of these findings, we suggest that C. sordellii should be considered in the differential diagnosis for infections of the internal umbilical remnant in foals.

Objective To determine whether training traditional birth attendants to manage several common perinatal conditions could reduce neonatal mortality in the setting of a resource poor country with limited access to healthcare. Design Prospective, cluster randomised and controlled effectiveness study. Setting Lufwanyama, an agrarian, poorly developed district located in the Copperbelt province, Zambia. All births carried out by study birth attendants occurred at mothers’ homes, in rural village settings. Participants 127 traditional birth attendants and mothers and their newborns (3559 infants delivered regardless of vital status) from Lufwanyama district. Interventions Using an unblinded design, birth attendants were cluster randomised to intervention or control groups. The intervention had two components: training in a modified version of the neonatal resuscitation protocol, and single dose amoxicillin coupled with facilitated referral of infants to a health centre. Control birth attendants continued their existing standard of care (basic obstetric skills and use of clean delivery kits). Main outcome measures The primary outcome was the proportion of liveborn infants who died by day 28 after birth, with rate ratios statistically adjusted for clustering. Secondary outcomes were mortality at different time points; and comparison of causes of death based on verbal autopsy data. Results Among 3497 deliveries with reliable information, mortality at day 28 after birth was 45% lower among liveborn infants delivered by intervention birth attendants than control birth attendants (rate ratio 0.55, 95% confidence interval 0.33 to 0.90). The greatest reductions in mortality were in the first 24 hours after birth: 7.8 deaths per 1000 live births for infants delivered by intervention birth attendants compared with 19.9 per 1000 for infants delivered by control birth attendants (0.40, 0.19 to 0.83). Deaths due to birth asphyxia were reduced by 63% among infants delivered by intervention birth attendants (0.37, 0.17 to 0.81) and by 81% within the first two days after birth (0.19, 0.07 to 0.52). Stillbirths and deaths from serious infection occurred at similar rates in both groups. Conclusions Training traditional birth attendants to manage common perinatal conditions significantly reduced neonatal mortality in a rural African setting. This approach has high potential to be applied to similar settings with dispersed rural populations. Trial registration Clinicaltrials.gov NCT00518856. PMID:21292711

1993-01-01

During the 1989 caribou (Rangifer tarandus) calving season on the Arctic National Wildlife Refuge, Alaska (USA), 61 calf carcasses were examined for cause of death and associated pathology. Dead calves were located by low-level aerial searches with two fixed-wing aircraft and a helicopter over high density calving areas between the Hulahula and Aichilik rivers. Primary diagnoses included emaciation (39%), malnutrition (8%), stillbirth (21%), trauma (16%), other primary causes (7%), and undetermined causes (8%). Twenty calves had contributory renal tubular degeneration. The findings indicate that factors contributing to nutritional deprivation in calves were the major cause of neonatal mortality; however, factors affecting stillbirth, abortion, or the urogenital system may have major effects on neonatal caribou and warrant further investigation.

To study the relations between different feeding patterns and the body weight retention of the perinatal women living in rural areas of China. A cluster sampling method was used to investigate 409 women, who are currently living in rural areas of Tianjin, at pregnant and perinatal status. While, their body weights and heights before pregnancy, antepartum and postpartum were measured, respectively. Body weight retention was the difference of the measured data after postpartum minus pre-pregnant weight. Variance analysis was used for statistic comparison. The rate of exclusive breastfeeding was 70.9% (290/409) within four months. The net body weight retention of women (5.8 kg) using the exclusive breastfeeding was lower than that of the women (7.0 kg) using artificial feeding within 4 - 6 months, but there was no significantly statistic difference (F = 1.45, P = 0.236). However, there was the opposite result within 7 - 9 months, the data showed that the body weight retention in the women using the exclusive breastfeeding was 4.9 kg, which was significantly higher than that the women (2.9 kg) with artificial feeding (F = 3.17, P = 0.043). The food consumption of the women (901 g) using exclusive breastfeeding was the highest, followed by those (877 g) using mixed feeding and the women (750 g) using artificial feeding. The body weight retention after postpartum should be related to infant feeding patterns. After postpartum, the weight loss of women using the exclusive breastfeeding is relatively low. While, for the women using the exclusive breastfeeding, the net weight retention during pregnancy and after postpartum were lower than those with artificial feeding. Therefore, it is necessary to enhance health education and guidance on promoting exclusive breast-feeding as well as increasing awareness on pre-pregnant health.

Perinatal asphyxia and hypoxia are common causes of morbidity in neonates. Prenatal birth associated with hypoxemia often results in several disorders because of the lack of oxygen in the brain. Survival rates from perinatal hypoxia have improved, but appropriate treatments for recovery are still limited, with great impact on patients, their families, society in general and health systems. The aim of this work is to contribute to a better understanding of the cellular mechanisms underlying the brainstem responses to hypoxia. For this purpose, distributions of two proteins, hypoxia-inducible factor-1 alpha (HIF-1α) and microtubule-associated protein 2 (MAP-2) were analyzed in brainstems of 11 children, four of them showing neuropathological evidence of brain hypoxia. They were included in control or hypoxic groups, and then in several subgroups according to their age. Immunohistochemical labeling for these proteins revealed only cell bodies containing HIF-1α, and both cell bodies and fibers positive for MAP-2 in the children's brainstems. The distribution of HIF-1α was more restricted than that of MAP-2, and it can be suggested that the expression of HIF-1α increased with age. The distribution pattern of MAP-2 in the medulla oblongata could be more due to age-related changes than to a response to hypoxic damage, whereas in the pons several regions, such as the nucleus ambiguus or the solitary nucleus, showed different immunolabeling patterns in controls and hypoxic cases. The distribution patterns of these two proteins suggest that some brainstem regions, such as the reticular formation or the central gray, could be less affected by conditions of hypoxia.

Abstract Objective To examine how the relaxation of the one child policy and policies to reduce caesarean section rates might have affected trends over time in caesarean section rates and perinatal and pregnancy related mortality in China. Design Observational study. Setting China’s National Maternal Near Miss Surveillance System (NMNMSS). Participants 6 838 582 births at 28 completed weeks or more of gestation or birth weight ≥1000 g in 438 hospitals in the NMNMSS between 2012 and 2016. Main outcome measures Obstetric risk was defined using a modified Robson classification. The main outcome measures were changes in parity and age distributions and relative frequency of each Robson group, crude and adjusted trends over time in caesarean section rates within each risk category (using Poisson regression with a robust variance estimator), and trends in perinatal and pregnancy related mortality over time. Results Caesarean section rates declined steadily between 2012 and 2016 (crude relative risk 0.91, 95% confidence interval 0.89 to 0.93), reaching an overall hospital based rate of 41.1% in 2016. The relaxation of the one child policy was associated with an increase in the proportion of multiparous births (from 34.1% in 2012 to 46.7% in 2016), and births in women with a uterine scar nearly doubled (from 9.8% to 17.7% of all births). Taking account of these changes, the decline in caesarean sections was amplified over time (adjusted relative risk 0.82, 95% confidence interval 0.81 to 0.84). Caesarean sections declined noticeably in nulliparous women (0.75, 0.73 to 0.77) but also declined in multiparous women without a uterine scar (0.65, 0.62 to 0.77). The decrease in caesarean section rates was most pronounced in hospitals with the highest rates in 2012, consistent with the government’s policy of targeting hospitals with the highest rates. Perinatal mortality declined from 10.1 to 7.2 per 1000 births over the same period (0.87, 0.83 to 0.91), and there was no change in pregnancy related mortality over time. Conclusions China is the only country that has succeeded in reverting the rising trends in caesarean sections. China’s success is remarkable given that the changes in obstetric risk associated with the relaxation of the one child policy would have led to an increase in the need for caesarean sections. China’s experience suggests that change is possible when strategies are comprehensive and deal with the system level factors that underpin overuse as well as the various incentives at work during a clinical encounter.

Maternal mortality has declined by nearly half since 1990, but over a quarter million women still die every year of causes related to pregnancy and childbirth. Maternal-health related targets are falling short of the 2015 Millennium Development Goals and a post-2015 Development Agenda is emerging. In connection with this, setting global research priorities for the next decade is now required. We adapted the methods of the Child Health and Nutrition Research Initiative (CHNRI) to identify and set global research priorities for maternal and perinatal health for the period 2015 to 2025. Priority research questions were received from various international stakeholders constituting a large reference group, and consolidated into a final list of research questions by a technical working group. Questions on this list were then scored by the reference working group according to five independent and equally weighted criteria. Normalized research priority scores (NRPS) were calculated, and research priority questions were ranked accordingly. A list of 190 priority research questions for improving maternal and perinatal health was scored by 140 stakeholders. Most priority research questions (89%) were concerned with the evaluation of implementation and delivery of existing interventions, with research subthemes frequently concerned with training and/or awareness interventions (11%), and access to interventions and/or services (14%). Twenty-one questions (11%) involved the discovery of new interventions or technologies. Key research priorities in maternal and perinatal health were identified. The resulting ranked list of research questions provides a valuable resource for health research investors, researchers and other stakeholders. We are hopeful that this exercise will inform the post-2015 Development Agenda and assist donors, research-policy decision makers and researchers to invest in research that will ultimately make the most significant difference in the lives of mothers and babies.

The aim of this study was to compare two neuroprotective strategies to supportive care in the treatment of perinatal asphyxia. A total of 67 term newborns with perinatal asphyxia were included and randomized into three groups: one group received supportive treatment; another group received a single dose of 40 mg/kg phenobarbital; and the third received three daily doses of 1000 IU/kg erythropoietin. The following parameters were analyzed: gestational age, birthweight, Apgar scores, cord blood pH, total serum antioxidant status (TAS), superoxide dismutase (SOD), glutathione peroxidase (GPx) and malondialdehyde (MDA). The newborns were included in the follow-up program and examined up to 18 months of age. TAS was higher in the erythropoietin group than in the other groups. SOD and GPx were lower for infants treated with phenobarbital or erythropoietin compared to control infants. MDA was lower in the erythropoietin group compared to the other groups, although the difference was not statistically significant (P > 0.05). The mortality rate was lower in the phenobarbital and erythropoietin groups (both 4.6%) than in the control group (17.4%). Long-term neurologic follow up showed a high incidence of sequelae in the control group compared to the phenobarbital and erythropoietin groups. Follow-up results were better in the phenobarbital group than in the erythropoietin group for motor and cognitive function at 3 and 6 months and worse for expressive language. At 18 months, however, the differences between these two groups were not significant. High-dose phenobarbital or erythropoietin along with supportive treatment has a positive influence on the outcome of newborns with perinatal asphyxia. Phenobarbital has the advantage of low cost and simplicity. © 2013 The Authors. Pediatrics International © 2013 Japan Pediatric Society.

The aim of this study was to investigate the relationship between the cerebro-umbilical ratio (CUR), measured at 30-34 weeks, and adverse intrapartum and perinatal outcomes. This was a retrospective cross-sectional cohort study of women delivering at the Mater Mothers' Hospital in Brisbane, Australia. Fetal Doppler indices for 1224 singleton pregnancies were correlated with maternal demographics and intrapartum and perinatal outcomes. Only women who attempted vaginal delivery were included in the study. Infants delivered by emergency cesarean section for fetal compromise had the lowest median CUR, 1.65 (IQR 1.17-2.12), compared to any other delivery group. The proportion of infants with a CUR ≤1 who required emergency cesarean section for fetal compromise was 33.3% compared to 9.3% of infants with a CUR >1 (adjusted OR 6.92 (95% CI 2.04-25.75), p<0.001). However, the detection rate of CUR ≤1 as a predictor for emergency cesarean delivery for fetal compromise was poor (18.9%). Detection rates increased in cohorts of infants born within two weeks of the scan or with birth weights <10th centile or <5th centile. Additionally, a CUR ≤1 was associated with lower median birth weight, higher rates of admission to the neonatal critical care unit and increased neonatal mortality. This study suggests that a CUR ≤1, measured at 30-34 weeks, is associated with a greater risk of emergency cesarean delivery for fetal compromise and a number of other adverse perinatal outcomes. The association was strongest in low birth weight babies. Copyright © 2016. Published by Elsevier Ireland Ltd.

Birth asphyxia is defined as the presence of hypoxia, hypercapnia, and acidosis leading the newborn to systemic disturbances probably electrolyte disturbance also. Knowledge of these electrolyte disturbances is very valuable as it can be an important parameter affecting perinatal morbidity, mortality and ongoing management. Serum sodium, potassium and ionized calcium of asphyxiated term newborn were sent within one hour of birth as per the inclusion criteria. Statistical comparison of mean values of different electrolytes between different groups of perinatal asphyxia was performed by ANOVA test for parametric data and significant data were further analyzed using post hoc test. Bivariate analysis was done to determine the correlations between Apgar score at 5 min and serum electrolytes. Pearson test was used to calculate the correlation coefficient. Box plot was used to show the median and quartile between serum electrolytes and Apgar score at 5 min. The mean values of sodium for mild, moderate and severe asphyxia were 135.52, 130.7 and 127.15 meq/l respectively. The values of potassium for mild, moderate and severe asphyxia were 4.96, 5.93 and 6.78 meq/l respectively. Similarly, the mean values of ionized calcium for mild, moderate and severe asphyxia were 1.07, 1.12 and 0.99 mmol/l respectively. The values of sodium and potassium among different severity of asphyxia were significantly different (p-value< 0.001). Significant positive correlation was found between serum sodium and Apgar score at 5 min. Significant negative correlation was present between serum potassium and Apgar score at 5 min. The degree of hyponatremia and hyperkalemia was directly proportional to the severity of birth asphyxia. So these electrolyte disturbances should always be kept in mind while managing cases of perinatal asphyxia and should be managed accordingly.

The purpose of the present review is to evaluate whether urine uric acid to creatinine ratio is increased in perinatal asphyxia and hypoxic-ischemic encephalopathy (HIE), as well as to assess its predictive accuracy in the disease. We used the Medline (1966-2017), Scopus (2004-2017), Clinicaltrials.gov (2008-2017), Embase (1980-2017), Cochrane Central Register of Controlled Trials CENTRAL (1999-2017), and Google Scholar (2004-2017) databases in our primary search along with the reference lists of electronically retrieved full-text papers. The hierarchical summary receiver operating characteristic (HSROC) model was used for the meta-analysis of diagnostic accuracy. Fourteen studies were finally included in the present review, that investigated 1226 neonates. Urinary uric acid to creatinine ratio was significantly higher in neonates with perinatal asphyxia than in healthy controls (mean differences (MD): 1.43 95%CI [1.17, 1.69]). Specifically, the mean difference for Sarnat stage 1 was 0.70 (95%CI [0.28, 1.13]), for stage 2 1.41 (95%CI [0.99, 1.84]), and for stage 3 2.71 (95%CI [2.08, 3.35]). The estimated sensitivity for the summary point was 0.90 (95%CI (0.82-0.95)), the specificity was 0.88 (95%CI (0.73-0.95)) and the diagnostic odds ratio was calculated at 63.62 (95%CI (17.08-236.96)). Urinary uric acid to creatinine ratio is a rapid and an easily detected biomarker that may help physicians identify neonates at risk of developing perinatal asphyxia and HIE. However, large-scale prospective studies are still needed to determine its value in predicting mortality, as well as short- and long-term adverse neurological outcomes.

Importance As perinatally HIV-infected youth (PHIVY) in the US grow older and more treatment-experienced, clinicians need updated information about the impact of age, CD4 count, viral load (VL), and antiretroviral drug (ARV) use on risks of opportunistic infections (OIs), key clinical events, and mortality in order to understand patient risks and improve care. Objective To determine the incidence or first occurrence during follow-up of key clinical events (including CDC-B and CDC-C events) and mortality among PHIVY stratified by age, CD4, and VL/ARV status. Design In the PHACS Adolescent Master Protocol (AMP) and IMPAACT P1074 multicenter cohort studies (2007–2015), we estimated event rates during person-time spent in key strata of age (7–12, 13–17, and 18–30 years), CD4 count (<200, 200–499, and ≥500 cells/μL), and VL/ARV status (< or ≥ 400 copies/mL; ARVs or no ARVs). Setting 41 ambulatory sites in the US, including Puerto Rico. Participants 1,562 participants in AMP and P1074 were eligible, 1446 PHIVY were included. Exposure(s) for observational studies Age, CD4 count, VL, ARV use. Main outcomes Clinical event rates stratified by person-time in age, CD4 count, and VL/ARV categories. Results During a mean follow-up of 4.9 years, higher incidences of CDC-B events, CDC-C events and mortality were observed as participants aged. Older PHIVY (13–17 and 18–30 year-olds) spent more time with VL ≥400 copies/mL and with CD4 <200/μL compared to 7–12 year-olds (30% and 44% vs. 22% of person-time with VL ≥400 copies/mL; 5% and 18% vs. 2% of person-time with CD4 <200/μL; p<0.01 for each comparison). We observed higher rates of CDC-B events, CDC-C events, bacterial infections, and mortality at lower CD4 counts, as expected. The mortality rate in older PHIVY was 6–12 times that of the general US population. Higher rates of sexually transmitted infections were also observed at lower CD4 counts, after adjusting for age. Conclusions and relevance Older PHIVY were at increased risk of viremia, immunosuppression, CDC-B events, CDC-C events, and mortality. Interventions to improve ART adherence and optimize models of care for PHIVY as they age are urgently needed to improve long-term outcomes among PHIVY. PMID:28346597

Intrauterine growth restriction (IUGR) is associated with higher rates of fetal, perinatal, and neonatal morbidity and mortality. The consequences of IUGR include short-term metabolic, hematological and thermal disturbances that lead to metabolic syndrome in children and adults. Additionally, IUGR severely affects short- and long-term fetal brain development and brain function (including motor, cognitive and executive function) and neurobehavior, especially neuropsychology. This review details the adverse effects of IUGR on fetal brain development and discusses intervention strategies.

To identify patterns of variation in breast cancer mortality in Europe (1980-2010), using a model-based approach. Mortality data were obtained from the World Health Organization database and mixed models were used to describe the time trends in the age-standardized mortality rates (ASMR). Model-based clustering was used to identify clusters of countries with homogeneous variation in ASMR. Three patterns were identified. Patterns 1 and 2 are characterized by stable or slightly increasing trends in ASMR in the first half of the period analysed, and a clear decline is observed thereafter; in pattern 1 the median of the ASMR is higher, and the highest rates were achieved sooner. Pattern 3 is characterised by a rapid increase in mortality until 1999, declining slowly thereafter. This study provides a general model for the description and interpretation of the variation in breast cancer mortality in Europe, based in three main patterns. Copyright © 2013 Elsevier Ltd.

This paper investigates the association between perinatal health and all-cause mortality for specific age intervals, assessing the contribution of maternal socioeconomic characteristics and the presence of maternal-level confounding. Our study is based on a cohort of 12,564 singletons born between 1915 and 1929 at the Uppsala University Hospital. We fitted Cox regression models to estimate age-varying hazard ratios of all-cause mortality for absolute and relative birth weight and for gestational age. We found that associations with mortality vary by age and according to the measure under scrutiny, with effects being concentrated in infancy, childhood or early adult life. For example, the effect of low birth weight was greatest in the first year of life and then continued up to 44 years of age (HR between 2.82 and 1.51). These associations were confirmed in within-family analyses, which provided no evidence of residual confounding by maternal characteristics. Our findings support the interpretation that policies oriented towards improving population health should invest in birth outcomes and hence in maternal health.

The myometrium must remain relatively quiescent during pregnancy to accommodate growth and development of the feto-placental unit, and then must transform into a highly coordinated, strongly contracting organ at the time of labour for successful expulsion of the new born. The control of timing of labour is complex involving interactions between mother, fetus and the placenta. The timely onset of labour and delivery is an important determinant of perinatal outcome. Both preterm birth (delivery before 37 week of gestation) and post term pregnancy (pregnancy continuing beyond 42 weeks) are both associated with a significant increase in perinatal morbidity and mortality. There are multiple paracrine/autocrine events, fetal hormonal changes and overlapping maternal/fetal control mechanisms for the triggering of parturition in women. Our current article reviews the mechanisms for uterine distension and reduced contractions during pregnancy and the parturition cascade responsible for the timely and spontaneous onset of labour at term. It also discusses the mechanisms of preterm labour and post term pregnancy and the clinical implications thereof. PMID:23776853

Head circumference at birth is an important neonatal parameter in view of its association with perinatal and postnatal morbidity and mortality. It is an indicator of brain volume and a tool for assessing the development of the central nervous system. Being a complex hereditary trait, predicting baby's head circumference from parental anthropometrics could complement the already existing ultrasonographic method of prediction. To identify the parental anthropometric determinants of baby's head circumference in Lagos, Nigeria, using a sample of patients attending a government hospital. Parental anthropometric parameters were obtained from 250 couples. The baby's head circumference was measured immediately after birth. The data were subjected to multivariate analysis. The parental variables that were most predictive of babies' head circumference were mid-parental weight, maternal height, maternal weight gain during pregnancy and maternal age. Assessment of these parental attributes can complement ultrasonographic data in predicting baby's head circumference for better perinatal outcome.

Individual-level epidemiologic studies of pregnancy outcomes after maternal influenza are limited in number and quality and have produced inconsistent results. We used a time-series design to investigate whether fluctuation in influenza virus circulation was associated with short-term variation in population-level rates of preterm birth, stillbirth, and perinatal death in Ontario between 2003 and 2012. Using Poisson regression, we assessed the association between weekly levels of circulating influenza virus and counts of outcomes offset by the number of at-risk gestations during 3 gestational exposure windows. The rate of preterm birth was not associated with circulating influenza level in the week preceding birth (adjusted rate ratio = 1.01, 95% confidence interval: 1.00, 1.02) or in any other exposure window. These findings were robust to alternate specifications of the model and adjustment for potential confounding. Stillbirth and perinatal death rates were similarly not associated with gestational exposure to influenza circulation during late pregnancy. We could not assess mortality outcomes relative to early gestational exposure because of missing dates of conception for many stillbirths. In this time-series study, population-level influenza circulation was not associated with short-term variation in rates of preterm birth, stillbirth, or perinatal death. © The Author 2016.

OBJECTIVE Despite improved perinatal survival following fetoscopic laser surgery (FLS) for twin twin transfusion syndrome (TTTS), prematurity remains an important contributor to perinatal mortality and morbidity. The objective of the study was to identify risk factors for complicated preterm delivery after FLS. STUDY DESIGN Retrospective cohort study of prospectively collected data on maternal/fetal demographics and pre-operative, operative and post-operative variables of 459 patients treated in 3 U.S. fetal centers. Multivariate linear regression was performed to identify significant risk factors associated with preterm delivery, which was cross-validated using K-fold method. Multivariate logistic regression was performed to identify risk factors for early vs. late preterm delivery based on median gestational age at delivery of 32 weeks. RESULTS There were significant differences in case selection and outcomes between the centers. After controlling for the center of surgery, a multivariate analysis indicated a lower maternal age at procedure, history of previous prematurity, shortened cervical length, use of amnioinfusion, 12 Fr cannula diameter, lack of a collagen plug placement and iatrogenic preterm premature rupture of membranes (iPPROM) were significantly associated with a lower gestational age at delivery. CONCLUSION Specific fetal/maternal and operative variables are associated with preterm delivery after FLS for the treatment of TTTS. Further studies to modify some of these variables may decrease the perinatal morbidity after laser therapy. PMID:24013922

Nitrergic system and plasmatic methylarginines: Evidence of their role in the perinatal programming of cardiovascular diseases.

Atherosclerosis, in turn preceded by endothelial dysfunction, underlies a series of important cardiovascular diseases. Reduced bioavailability of endothelial nitric oxide, by increasing vascular tone and promoting platelet aggregation, leukocyte adhesion, and smooth muscle cell proliferation, plays a key role in the onset of the majority of cardiovascular diseases. In addition, high blood levels of asymmetric dimethylarginine, a potent inhibitor of nitric oxide synthesis, are associated with future development of adverse cardiovascular events and cardiac death. Recent reports have demonstrated that another methylarginine, i.e., symmetric dimethylarginine, is also involved in the onset of endothelial dysfunction and hypertension. Almost a decade ago, prematurity at birth and intrauterine growth retardation were first associated with a potential negative influence on the cardiovascular apparatus, thus constituting risk factors or leading to early onset of cardiovascular diseases. This condition is referred to as cardiovascular perinatal programming. Accordingly, cardiovascular morbidity and mortality are higher among former preterm adults than in those born at term. The aim of this paper was to undertake a comprehensive literature review focusing on cellular and biochemical mechanisms resulting in both reduced nitric oxide bioavailability and increased methylarginine levels in subjects born preterm. Evidence of the involvement of these compounds in the perinatal programming of cardiovascular risk are also discussed. Copyright © 2015 Elsevier B.V. All rights reserved.

Current management of the infant who presents with neonatal encephalopathy.

Neonatal encephalopathy after perinatal hypoxic-ischemic insult is a major contributor to global child mortality and morbidity. Brain injury in term infants in response to hypoxic-ischemic insult is a complex process evolving over hours to days, which provides a unique window of opportunity for neuroprotective treatment interventions. Advances in neuroimaging, brain monitoring techniques, and tissue biomarkers have improved the ability to diagnose, monitor, and care for newborn infants with neonatal encephalopathy as well as predict their outcome. However, challenges remain in early identification of infants at risk for neonatal encephalopathy, determination of timing and extent of hypoxic-ischemic brain injury, as well as optimal management and treatment duration. Therapeutic hypothermia is the most promising neuroprotective intervention to date for infants with moderate to severe neonatal encephalopathy after perinatal asphyxia and has currently been incorporated in many neonatal intensive care units in developed countries. However, only 1 in 6 babies with encephalopathy will benefit from hypothermia therapy; many infants still develop significant adverse outcomes. To enhance the outcome, specific diagnostic predictors are needed to identify patients likely to benefit from hypothermia treatment. Studies are needed to determine the efficacy of combined therapeutic strategies with hypothermia therapy to achieve maximal neuroprotective effect. This review focuses on important concepts in the pathophysiology, diagnosis, and management of infants with neonatal encephalopathy due to perinatal asphyxia, including an overview of recently introduced novel therapies. © 2011 Published by Mosby, Inc.

To assess the effect of dietary patterns on all deaths and diabetes-related deaths in the Japanese Elderly Diabetes Intervention Trial (J-EDIT). We investigated relationships between that of overall mortality and dietary pattern, and diabetes-related deaths and dietary pattern as observed among 912 registered cases of the J-EDIT study, which is a prospective follow-up study of elderly Japanese type 2 diabetic patients. Factor analysis with the factor number 3 led to deriving three dietary patterns (healthy type, snack type and greasy type). The relationship between these patterns and overall mortality or diabetes-related death was investigated. Although not statistically significant, there was a lower tendency of overall mortality and diabetes-related deaths for the healthy type dietary pattern. When the tendencies of overall mortality were analyzed for "young-old," who are younger than 75 years-of age, and "old-old" of over 75 years-of-age, the mortality rate for the greasy type and healthy type dietary patterns were nearly the same and higher than the snack type dietary pattern in young-old. In contrast, in old-old, a higher mortality rate was reported for the greasy type dietary pattern and a lower mortality rate was reported for the healthy type dietary pattern. The hazard ratio by Cox regression analysis for greasy type to healthy type in old-old was 3.03 (P = 0.04, CI 1.07-8.57). Furthermore, in old-old, as vegetable consumption increased, the lower the tendency foroverall mortality, and the more fish that was consumed, the overall mortality significantly decreased (P = 0.020) in the tertile. The greasy type dietary pattern with an increased amount of sugar, fat and meat led to poor life prognosis for elderly Japanese type 2 diabetic patients. The healthy type dietary pattern rich in vegetable and fish, which is similar to the Mediterranean diet and Dietary Approach to Stop Hypertension diet, was suggested to improve life prognosis. © 2012 Japan Geriatrics Society.

Patterns of natural mortality in stream-living brown trout (Salmo trutta)

We tested the hypothesis that lifetime mortality patterns and their corresponding rates and causal factors differ among populations of stream-living salmonids. To this end, we examined the lifetime mortality patterns of several successive cohorts of two stream-living brown trout (Salmo trutta) populations in Spain and Denmark. In the southern population, we observed a consistent two-phase pattern, in which mortality was negligible during the first half of the lifetime and severe during the rest of the lifetime. In contrast, the northern population demonstrated a three-phase pattern with an earlier phase varying from negligible to severe, followed by a second stage of weak mortality, and lastly by a third life stage of severe mortality. Despite substantial differences in the mortality patterns between the two populations, the combined effect of recruitment (as a proxy of the density-dependent processes occurring during the lifetime) and mean body mass (as a proxy of growth experienced by individuals in a given cohort) explained c. 89% of the total lifetime mortality rates across cohorts and populations. A comparison with other published data on populations of stream-living brown trout within its native range highlighted lifetime mortality patterns of one, two, three and four phases, but also suggested that common patterns may occur in populations that experience similar individual growth and population density. ?? 2011 Blackwell Publishing Ltd.

Abstract Objective To present data from a 2008 infant mortality survey conducted in Jordan, Lebanon, the Syrian Arab Republic, the Gaza Strip and the West Bank and analyse infant mortality trends among Palestine refugees in 1995–2005. Methods Following the preceding birth technique, mothers who were registering a new birth were asked if the preceding child was alive or dead, the day the child was born and the date of birth of the neonate whose birth was being registered. From this information, neonatal, infant and early child mortality rates were estimated. The age at death for early child mortality was determined by the mean interval between successive births and the mean age of neonates at registration. Findings In 2005–2006, infant mortality among Palestine refugees ranged from 28 deaths per 100 000 live births in the Syrian Arab Republic to 19 in Lebanon. Thus, infant mortality in Palestine refugees is among the lowest in the Near East. However, infant mortality has stopped decreasing in recent years, although it remains at a level compatible with the attainment of Millennium Development Goal 4. Conclusion Largely owing to the primary health care provided by the United Nations Relief and Works Agency (UNRWA) for Palestine Refugees in the Near East and other entities, infant mortality among Palestine refugees had consistently decreased. However, it is no longer dropping. Measures to address the most likely reasons – early marriage and childbearing, poor socioeconomic conditions and limited access to good perinatal care – are needed.

Measures to address the most likely reasons - early marriage and childbearing, poor socioeconomic conditions and limited access to good perinatal care - are needed.

Several studies reported that primary care improves health outcomes for populations. The objective of this study was to examine the relationship between the supply of primary care physicians and population health outcomes in Korea. Data were extracted from the 2007 report of the Health Insurance Review, the 2005 report from the Korean National Statistical Office, and the 2008 Korean Community Health Survey. The dependent variables were age-adjusted all-cause and disease-specific mortality rates, and independent variables were the supply of primary care physicians, the ratio of primary care physicians to specialists, the number of beds, socioeconomic factors (unemployment rate, local tax, education), population (population size, proportion of the elderly over age 65), and health behaviors (smoking, exercise, using seat belts rates). We used multivariate linear regression as well as ANOVA and t tests. A higher number of primary care physicians was associated with lower all-cause mortality, cancer mortality, and cardiovascular mortality. However, the ratio of primary care physicians to specialists was not related to all-cause mortality. In addition, the relationship between socioeconomic variables and mortality rates was similar in strength to the relationship between the supply of primary care physicians and mortality rates. Accident mortality, suicide mortality, infection mortality, and perinatal mortality were not related to the supply of primary care physicians. The supply of primary care physicians is associated with improved health outcomes, especially in chronic diseases and cancer. However, other variables such as the socioeconomic factors and population factors seem to have a more significant influence on these outcomes.

The present study examined the effects of Delta(9)-tetrahydrocannabinol (Delta(9)-THC) when administered during the perinatal period on morphine self-administration in adulthood. To this end, pregnant Wistar rats were daily exposed to Delta(9)-THC from the fifth day of gestation up to pup weaning, when they were separated by gender and left to mature to be used for analyses of operant food- and morphine-reinforced behavior in a progressive ratio (PR) schedule. We also analyzed dopaminergic activity (DOPAC/DA) in reward-related structures during specific phases of the behavioral study. In both reinforcement paradigms, food and morphine, females always reached higher patterns of self-administration than males, but this occurred for the two treatment groups, Delta(9)-THC or vehicle. These higher patterns measured in females corresponded with a higher DOPAC/DA in the nucleus accumbens prior to the onset of morphine self-administration in comparison to males. Interestingly, DOPAC/DA was lower in Delta(9)-THC-exposed females compared to oil-exposed females and similar to oil- and Delta(9)-THC-exposed males. In addition, Delta(9)-THC-exposed females also exhibited a reduction in DOPAC/DA in the ventral tegmental area, which did not exist in males. All these changes, however, disappeared after 15 days of morphine self-administration and they did not reappear after 15 additional days of extinction of this response. Our data suggest that females are more vulnerable than males in a PR schedule for operant food and morphine self-administration; perinatal Delta(9)-THC exposure is not a factor influencing this vulnerability. The neurochemical analysis revealed that the activity of limbic dopaminergic neurons prior to morphine self-administration was higher in females than males, as well as that the perinatal Delta(9)-THC treatment reduced the activity of these neurons only in females, although this had no influence on morphine vulnerability in these animals.

The aim of this study was to investigate trajectories of sleep quality and associations with mood in the perinatal period. Although it is commonly accepted that subjective sleep quality declines during pregnancy and the transition to parenthood, some women may follow qualitatively distinct trajectories. Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). Data were collected from 293 women at four time points: during early pregnancy, at Time 1 (T1; < 22 w gestational age [GA]; late pregnancy, at Time 2 (T2; 32 w GA); during the postnatal period at Time 3 (T3; 3 mo postpartum); and Time 4 (T4; 6 mo postpartum). A group-based semiparametric mixture model was used to estimate patterns of sleep quality throughout the perinatal period. Four trajectory groups were identified, including patterns defined by high sleep quality throughout (21.5%), mild decrease in sleep quality (59.5%), significant decrease in sleep quality (12.3%) and a group with poor sleep quality throughout (6.7%). Women who had the worst sleep quality at Time 1 and those who experienced significant increases in sleep problems throughout pregnancy were also the groups who reported the highest levels of anxiety and depressive symptoms in early pregnancy and the lowest levels of social support. After controlling for covariates, the groups with worst subjective sleep quality during pregnancy were also the most likely to experience high symptoms of depression in the postpartum period. Most of the women in our sample reported mild sleep disturbances through the perinatal period. A subgroup of women reported a significant decline in sleep quality from early to late pregnancy and another reported poor subjective sleep quality throughout pregnancy; these groups had the greatest risk of experiencing high symptoms of depression in the postpartum period. © 2015 Associated Professional Sleep Societies, LLC.

The evidence on trajectories of perinatal depression is mostly based on studies composed of women at high risk for poor mental health. Research on maternal anxiety trajectories is also scarce. Using a large community cohort, the All Our Babies study, in Alberta, Canada, we examined trajectories of perinatal depressive and anxiety symptoms and compared characteristics of women across trajectories. Anxiety and depressive symptoms were measured at the second and third trimesters and at 4 and 12 months postpartum among 1,445 women recruited between May 2008 and December 2010. The state subscale of the Spielberger State-Trait Anxiety Inventory was used to measure anxiety symptoms, and depressive symptoms were measured with the Edinburgh Postnatal Depression Scale. Semiparametric group-based mixed modeling was performed to identify the optimal trajectory shape, number of groups, and proportion of the sample belonging to each trajectory. Model fit was evaluated using the Bayesian information criterion. Multinomial logistic regression analysis was conducted to compare characteristics across the trajectories. Five distinct trajectory groups with constant and variable patterns were identified for both depressive and anxiety symptoms: minimal, mild, antepartum, postpartum, and chronic. Common risk factors of depression and anxiety across groups with elevated symptoms were history of mental health issues (odds ratios [ORs] varied from 1.83 to 7.64), history of abuse/neglect (ORs varied from 1.67 to 8.97), and low social support (ORs varied from 1.64 to 11.37). The magnitude of the influence of the psychosocial risk factors was greater in the chronic group compared to others, suggesting a dose-related relationship. Heterogeneity of anxiety and depressive symptoms highlights the importance of multiple mental health assessments during the perinatal period. The patterns and intensity of postpartum depression differed between community and high-risk samples, underlining the significance of defining suitable cutoffs. Research to examine the impact of these trajectories on child outcomes is needed. © Copyright 2016 Physicians Postgraduate Press, Inc.

Invasive group A streptococci infections in pregnancy have historically led to severe maternal and neonatal morbidity and mortality. We are reporting a rare and novel case of successful treatment of third-trimester group A streptococci infection with early, aggressive intervention and maintenance of the pregnancy to term. A 35 year old woman initially presented with fever, flu-like symptoms, and preterm contractions at 34 weeks of gestation. She demonstrated signs of early stages of septic shock, ultimately attributed to group A streptococci bacteremia. Early, aggressive intervention allowed the pregnancy to continue until 38 weeks of gestation with normal maternal and neonatal outcomes. Early and aggressive treatment of invasive group A streptococci infection during pregnancy can potentially avoid severe maternal and perinatal morbidity and mortality with a successful continuation of pregnancy.

Induced abortion: epidemiological aspects.

Baird, D

1975-01-01

Sir Dugald Baird sketches the history of abortion legislation in Great Britain from the beginning of the century. In his views the 1967 Abortion Act has been one of the most important and beneficial pieces of social legislation enacted in Britain in the last 100 years. It has, however, brought problems both of administration in the hospitals and to individual doctors and nurses, particularly when the patients are young single women and even schoolgirls. One of the consequences of the Abortion Act has been a fall in maternal mortality and perinatal mortality rates. Abortion does not seem to be followed by serious emotional sequelae. Nevertheless recent changes in sexual mores have introduced new and serious social problems which are discussed in relation to the role of the doctor in his relationship with patients seeking abortion.

A population-based birth registry has been set up for the Arctic town of Moncegorsk in north-western Russia. In this investigation, the quality and the content of the registry are assessed and the perinatal mortality (PM) rates in the period 1973-97 estimated. Enrollment in the Kola Birth Registry (KBR) involved the retrospective inclusion of all births with at least 28 weeks of gestation in Moncegorsk in the period 1973-97. The data in the registry were assessed for data entry errors, completeness of data and population coverage. The annual PM rates were estimated for live- and stillborns with at least 28 weeks of gestation. The KBR contains detailed information about the newborn, delivery, pregnancy and mother for 21 214 births by women from Moncegorsk, covering at least 96% of all the births by the population in the period studied. No records were missing data for gender and birth date of the newborn, and more than 99.9% of the records contained data about gestational age and birthweight. Data concerning the mothers' employment were missing in 0.4% of the records. The annual PM rate fell from more than 20 to less than 10 deaths per 1000 births during this period. The KBR provides an extensive data source useful for case-control and register-based prospective studies, and constitutes the first such compilation in Russia. The homogeneity of the population in Moncegorsk makes it advantageous for epidemiological investigations. The PM rate in Moncegorsk was lower than the overall rate in Russia.

Delayed interval delivery in multiple gestations.

PubMed

Platt, J S; Rosa, C

1999-05-01

The incidence of higher-order gestations is increasing primarily as a result of menstrual cycle manipulation, with concomitant increased risk in maternal and fetal complications. Perinatal mortality rates range between 47 and 120 per 1000 births for twins and 93 to 203 per 1000 births for triplets. The critical period of perinatal mortality and morbidity is between weeks 23 and 28 of gestation. Attention has recently turned to methods of delaying the birth of second and higher order fetuses to improve newborn survival and decrease neonatal morbidity in these high-risk pregnancies. We report two cases of delayed interval delivery. Neither pregnancy involved a monochorionic/monoamniotic gestation. The first case was a twin gestation delivered at 21 weeks with an interval of 5 days and extreme prematurity of both twins. The second case was a triplet gestation delivered at 21 weeks with an interval of 5 days. Triplet A was stillborn; triplets B and C succumbed in extreme prematurity. Preterm labor in multiple gestations usually results in delivery of all fetuses. On occasion, the uterus will spontaneously cease to contract after the birth of one or more premature infants. Review of the literature now reports 48 twin pregnancies exposed to delayed interval delivery with 40 surviving infants of 96 fetuses. Whereas delaying the delivery of remaining fetuses improves their prognosis, there is currently no consensus regarding technique nor is there statistical significance in techniques currently used. Furthermore, study is indicated to reduce preterm birth and associated costs.

The purpose of this study was to determine the circumstances in which trial of scar is conducted in the obstetric unit of Tikur Anbessa Hospital, Addis Ababa, Ethiopia, and evaluate the safety of the undertaking in terms of maternal and perinatal morbidity and mortality. Between 11 September, 1991 to 10 September, 1992, 66 women with previous caesarean section were given a trial of scar. The main pre-requests to allow a trial of scar were: only one previous lower uterine segment section, a cephalic presentation with no disproportion in the current labour and, the presence of a functional operating theatre. Labour was being monitored by checking the uterine contractions by fundal palpation and counting the Foetal heart rate (FHR) using the Pinnard Stethoscope. Compatible blood was prior prepared in only 7 (10.6%) labours. Forty seven (71.2%) parturients delivered vaginally. In 19 (28.2%) an emergency repeat section was done for failure of progress in labour. In one (1.5%) patient, a uterine scar dehiscence was detected. The 5th minute APGAR score was 7/10 or more in 64 (94.1%) and 6/10 in 3 (4.5%) of 68 neonates. There was one prepartum intra-uterine foetal death and one neonatal death of a preterm baby making the perinatal mortality rate (PNMR) of 29.4 per thousand. There was no maternal death. In conclusion, this study demonstrates that a trial of scar was a safe procedure.

To examine the effects and safety of high-dose (compared with low-dose) oxytocin regimen for labor augmentation on perinatal outcomes. Data from the Consortium on Safe Labor were used. A total of 15,054 women from six hospitals were eligible for the analysis. Women were grouped based on their oxytocin starting dose and incremental dosing of 1, 2, and 4 milliunits/min. Duration of labor and a number of maternal and neonatal outcomes were compared among these three groups stratified by parity. Multivariable logistic regression and generalized linear mixed model were used to adjust for potential confounders. Oxytocin regimen did not affect the rate of cesarean delivery or other perinatal outcomes. Compared with 1 milliunit/min, the regimens starting with 2 milliunits/min and 4 milliunits/min reduced the duration of first stage by 0.8 hours (95% confidence interval 0.5-1.1) and 1.3 hours (1.0-1.7), respectively, in nulliparous women. No effect was observed on the second stage of labor. Similar patterns were observed in multiparous women. High-dose regimen was associated with a reduced risk of meconium stain, chorioamnionitis, and newborn fever in multiparous women. High-dose oxytocin regimen (starting dose at 4 milliunits/min and increment of 4 millliunits/min) is associated with a shorter duration of first-stage of labor for all parities without increasing the cesarean delivery rate or adversely affecting perinatal outcomes.

Thirty-three families, each with a premature infant born less than 33 gestational weeks, were observed in a longitudinal exploratory study. Infants were recruited in a neonatal intensive care unit, and follow-up visits took place at 4 months and 12 months of corrected age. The severity of the perinatal problems was evaluated using the Perinatal Risk Inventory (PERI; A.P. Scheiner & M.E. Sexton, 1991). At 4 months, mother-infant play interaction was observed and coded according to the CARE-index (P.M. Crittenden, 2003); at 12 months, the Strange Situation Procedure (SSP; M.D.S. Ainsworth, M.C. Blehar, E. Waters, & S. Wall, 1978) was administered. Results indicate a strong correlation between the severity of perinatal problems and the quality of attachment at 12 months. Based on the PERI, infants with high medical risks more frequently tended to be insecurely attached. There also was a significant correlation between insecure attachment and dyadic play interaction at 4 months (i.e., maternal controlling behavior and infant compulsive compliance). Moreover, specific dyadic interactive patterns could be identified as protective or as risk factors regarding the quality of attachment. Considering that attachment may have long-term influence on child development, these results underline the need for particular attention to risk factors regarding attachment among premature infants.

The women's professional help-seeking rate for perinatal depression is low, despite the prevalent and disabling nature of this condition. Therefore, new approaches should be implemented to increase women's access and utilization of treatment resources, namely e-mental health tools. This study aimed to characterize women's current pattern of use of online resources for mental heal issues and women's acceptance of e-mental health tools during the perinatal period, and to investigate its main determinants. This study used an online cross-sectional survey that was completed by 546 women during the perinatal period. 31.3% had prior knowledge of websites targeting mental health illness. Women presenting an actual need for help (i.e., a positive screen for depression) reported greater use of online resources and greater engagement in e-health behaviors related to mental health (d=0.46-0.61), and being more accepting of e-mental health tools, particularly of informative websites. Women's perceptions concerning the e-mental tools were found to predict their intentions to use them. The results seem to globally support Portuguese women's acceptance of e-mental health tools. To improve the level of acceptance, women should be involved as stakeholders in the development of new e-mental health tools and provided with specific information before their utilization.

Perinatal psychiatric episodes comprise various disorders and symptom severity, which are diagnosed and treated in multiple treatment settings. To date, no studies have quantified the incidence and prevalence of perinatal psychiatric episodes treated in primary and secondary care, which we aimed to do in the present study. We designed a descriptive prospective study and included information from Danish population registers to study first-time ever and recurrent psychiatric episodes during the perinatal period, including treatment at psychiatric facilities and general practitioners (GPs). This was done for all women who had records of one or more singleton births from 1998 until 2012. In total, we had information on 822 439 children born to 491 242 unique mothers. Results showed first-time psychiatric episodes treated at inpatient facilities were rare during pregnancy, but increased significantly shortly following childbirth (0.02 vs 0.25 per 1000 births). In comparison, first-time psychiatric episodes treated at outpatient facilities were more common, and showed little variation across pregnancy and postpartum. For every single birth resulting in postpartum episodes treated at inpatient psychiatric facilities, 2.5 births were followed by an episode treated at outpatient psychiatric facility and 12 births by GP-provided pharmacological treatment. We interpret our results the following way: treated severe and moderate psychiatric disorders have different risk patterns in relation to pregnancy and childbirth, which suggests differences in the underlying etiology. We further speculate varying treatment incidence and prevalence in pregnancy vs postpartum may indicate that the current Diagnostic and Statistical Manual of Mental Disorders-5 peripartum specifier not adequately describes at-risk periods across moderate and severe perinatal psychiatric episodes.

Regional Variation in Antenatal Corticosteroid Use: A Network-Level Quality Improvement Study

PubMed Central

Goldstein, B.A.; Tamaresis, J.; Kan, P.; Lee, H.C.

2015-01-01

BACKGROUND AND OBJECTIVES: Examination of regional care patterns in antenatal corticosteroid use (ACU) rates may be salient for the development of targeted interventions. Our objective was to assess network-level variation using California perinatal care regions as a proxy. We hypothesized that (1) significant variation in ACU exists within and between California perinatal care regions, and (2) lower performing regions exhibit greater NICU-level variability in ACU than higher performing regions. METHODS: We undertook cross-sectional analysis of 33 610 very low birth weight infants cared for at 120 hospitals in 11 California perinatal care regions from 2005 to 2011. We computed risk-adjusted median ACU rates and interquartile ranges (IQR) for each perinatal care region. The degree of variation was assessed using hierarchical multivariate regression analysis with NICU as a random effect and region as a fixed effect. RESULTS: From 2005 to 2011, mean ACU rates across California increased from 82% to 87.9%. Regional median (IQR) ACU rates ranged from 68.4% (24.3) to 92.9% (4.8). We found significant variation in ACU rates among regions (P < .0001). Compared with Level IV NICUs, care in a lower level of care was a strongly significant predictor of lower odds of receiving antenatal corticosteroids in a multilevel model (Level III, 0.65 [0.45–0.95]; Level II, 0.39 [0.24–0.64]; P < .001). Regions with lower performance in ACU exhibited greater variability in performance. CONCLUSIONS: We found significant variation in ACU rates among California perinatal regions. Regional quality improvement approaches may offer a new avenue to spread best practice. PMID:25601974

Newborn deaths account for 57% of deaths in children younger than 5 years in Pakistan. Although a large programme of trained lady health workers (LHWs) exists, the effectiveness of this training on newborn outcomes has not been studied. We aimed to evaluate the effectiveness of a community-based intervention package, principally delivered through LHWs working with traditional birth attendants and community health committees, for reduction of perinatal and neonatal mortality in a rural district of Pakistan. We undertook a cluster randomised trial between February, 2006, and March, 2008, in Hala and Matiari subdistricts, Pakistan. Catchment areas of primary care facilities and all affiliated LHWs were used to define clusters, which were allocated to intervention and control groups by restricted, stratified randomisation. The intervention package delivered by LHWs through group sessions consisted of promotion of antenatal care and maternal health education, use of clean delivery kits, facility births, immediate newborn care, identification of danger signs, and promotion of careseeking; control clusters received routine care. Independent data collectors undertook quarterly household surveillance to capture data for births, deaths, and household practices related to maternal and newborn care. Data collectors were masked to cluster allocation; those analysing data were not. The primary outcome was perinatal and all-cause neonatal mortality. Analysis was by intention to treat. This trial is registered, ISRCTN16247511. 16 clusters were assigned to intervention (23,353 households, 12,391 total births) and control groups (23,768 households, 11,443 total births). LHWs in the intervention clusters were able to undertake 4428 (63%) of 7084 planned group sessions, but were only able to visit 2943 neonates (24%) of a total 12,028 livebirths in their catchment villages. Stillbirths were reduced in intervention clusters (39·1 stillbirths per 1000 total births) compared with control (48·7 per 1000; risk ratio [RR] 0·79, 95% CI 0·68-0·92; p=0·006). The neonatal mortality rate was 43·0 deaths per 1000 livebirths in intervention clusters compared with 49·1 per 1000 in control groups (RR 0·85, 0·76-0·96; p=0·02). Our results support the scale-up of preventive and promotive maternal and newborn interventions through community health workers and emphasise the need for attention to issues of programme management and coverage for such initiatives to achieve maximum potential.

Association of bovine leptin polymorphisms with energy output and energy storage traits in progeny tested Holstein-Friesian dairy cattle sires

PubMed Central

2010-01-01

Background Leptin modulates appetite, energy expenditure and the reproductive axis by signalling via its receptor the status of body energy stores to the brain. The present study aimed to quantify the associations between 10 novel and known single nucleotide polymorphisms in genes coding for leptin and leptin receptor with performance traits in 848 Holstein-Friesian sires, estimated from performance of up to 43,117 daughter-parity records per sire. Results All single nucleotide polymorphisms were segregating in this sample population and none deviated (P > 0.05) from Hardy-Weinberg equilibrium. Complete linkage disequilibrium existed between the novel polymorphism LEP-1609, and the previously identified polymorphisms LEP-1457 and LEP-580. LEP-2470 associated (P < 0.05) with milk protein concentration and calf perinatal mortality. It had a tendency to associate with milk yield (P < 0.1). The G allele of LEP-1238 was associated (P < 0.05) with reduced milk fat concentration, reduced milk protein concentration, longer gestation length and tended to associate (P < 0.1) with an increase in calving difficulty, calf perinatal mortality and somatic cells in the milk. LEP-963 exhibited an association (P < 0.05) with milk fat concentration, milk protein concentration, calving difficulty and gestation length. It also tended to associate with milk yield (P < 0.1). The R25C SNP associated (P < 0.05) with milk fat concentration, milk protein concentration, calving difficulty and length of gestation. The T allele of the Y7F SNP significantly associated with reduced angularity (P < 0.01) and reduced milk protein yield (P < 0.05). There was also a tendency (P < 0.1) for Y7F to associate with increased body condition score, reduced milk yield and shorter gestation (P < 0.1). A80V associated with reduced survival in the herd (P < 0.05). Conclusions Several leptin polymorphisms (LEP-2470, LEP-1238, LEP-963, Y7F and R25C) associated with the energetically expensive process of lactogenesis. Only SNP Y7F associated with energy storage. Associations were also observed between leptin polymorphisms and calving difficulty, gestation length and calf perinatal mortality. The lack of an association between the leptin variants investigated with calving interval in this large data set would question the potential importance of these leptin variants, or indeed leptin, in selection for improved fertility in the Holstein-Friesian dairy cow.

Vaginal birth after one previous caesarean section in a tertiary institution in Nigeria.

Vaginal birth after one previous lower segment caesarean section represents one of the most significant and challenging issues in obstetric practice. A 5-year retrospective study was carried out at the University of Benin Teaching Hospital between January 1999 and December 2003, to determine the incidence, the maternal and fetal outcome following vaginal delivery after one previous caesarean section with a view to evaluating its safety and efficacy. There were 5234 deliveries, with 395 cases of one previous caesarean section, giving an incidence of 7.5%. The incidences of emergency caesarean section, elective caesarean section and spontaneous vaginal delivery following trial of vaginal delivery were 34.7%, 9.4% and 48.1%, respectively. During the study period there were 1317 cases of caesarean section, giving an incidence of 25.2% caesarean section rate. The incidence of one previous section among all caesarean section births was 30%. The major morbidity following vaginal delivery was uterine rupture with an incidence of 1.5% and hysterectomy of 0.8%. Three of the uterine ruptures occurred before admission because the patients laboured at home. One maternal death occurred as a result of uterine rupture and postpartum haemorrhage, giving a maternal mortality ratio of 19/100,000 and a case fatality rate of 0.3%. The corrected perinatal mortality rate was 15.2/1000, mainly from obstructed labour, abruptio placenta and fetal distress. Both maternal and fetal mortalities from vaginal birth after one previous section were significantly less than the respective overall maternal and fetal mortality from the institution. The 1-minute apgar score of babies delivered by elective section was significantly (P < 0.001) higher than the apgar score of babies delivered by emergency section and vaginally. There was only one patient with wound dehiscence at elective section without associated perinatal death. Vaginal delivery following caesarean section is relatively safe. However, women in developing countries will continue to require counselling to counter the myths of aversion to operative delivery even at the expense of losing their lives. Our hospitals should have adequate monitoring equipment for high-risk pregnancies so that patients and their babies can be assured of survival.

ABSTRACT OBJECTIVE The objective of this study was to test the validity of the pragmatic criteria of the definitions of neonatal near miss, extending them throughout the infant period, and to estimate the indicators of perinatal care in public maternity hospitals. METHODS A cohort of live births from six maternity hospitals in the municipalities of São Paulo, Niterói, and Rio de Janeiro, Brazil, was carried out in 2011. We carried out interviews and checked prenatal cards and medical records. We compared the pragmatic criteria (birth weight, gestational age, and 5’ Apgar score) of the definitions of near miss of Pileggi et al., Pileggi-Castro et al., Souza et al., and Silva et al. We calculated sensitivity, specificity (gold standard: infant mortality), percentage of deaths among newborns with life-threatening conditions, and rates of near miss, mortality, and severe outcomes per 1,000 live births. RESULTS A total 7,315 newborns were analyzed (completeness of information > 99%). The sensitivity of the definition of Pileggi-Castro et al. was higher, resulting in a higher number of cases of near miss, Souza et al. presented lower value, and Pileggi et al. and de Silva et al. presented intermediate values. There is an increase in sensitivity when the period goes from 0–6 to 0–27 days, and there is a decrease when it goes to 0–364 days. Specificities were high (≥ 97%) and above sensitivities (54% to 77%). One maternity hospital in São Paulo and one in Niterói presented, respectively, the lowest and highest rates of infant mortality, near miss, and frequency of births with life-threatening conditions, regardless of the definition. CONCLUSIONS The definitions of near miss based exclusively on pragmatic criteria are valid and can be used for monitoring purposes. Based on the perinatal literature, the cutoff points adopted by Silva et al. were more appropriate. Periodic studies could apply a more complete definition, incorporating clinical, laboratory, and management criteria, including congenital anomalies predictive of infant mortality. PMID:29211204

We hypothesized that patterns of elevated stroke mortality among those born in the United States Stroke Belt (SB) states also prevailed for mortality related to all-cause dementia or Alzheimer Disease. Cause-specific mortality (contributing cause of death, including underlying cause cases) rates in 2000 for United States-born African Americans and whites aged 65 to 89 years were calculated by linking national mortality records with population data based on race, sex, age, and birth state or state of residence in 2000. Birth in a SB state (NC, SC, GA, TN, AR, MS, or AL) was cross-classified against SB residence at the 2000 Census. Compared with those who were not born in the SB, odds of all-cause dementia mortality were significantly elevated by 29% for African Americans and 19% for whites born in the SB. These patterns prevailed among individuals who no longer lived in the SB at death. Patterns were similar for Alzheimer Disease-related mortality. Some non-SB states were also associated with significant elevations in dementia-related mortality. Dementia mortality rates follow geographic patterns similar to stroke mortality, with elevated rates among those born in the SB. This suggests important roles for geographically patterned childhood exposures in establishing cognitive reserve.

The birth rate in Belgium decreased between 1964 and 1975, after which the birth rate again began to increase. This increase was not enough, however, to justify classifying Belgium's population as expansive. The decrease in fertility was due mainly to a decrease in the fertility of women in the highest fertility age groups. This development began to spread into lower age groups but was reversed by trends toward more traditional family patterns. After 1961, couples showed a preference for remaining childless for the first several years following their marriage, for the 2 child family, and for longer birth intervals. The decrease in fertility was greater among those with larger families, among the inhabitants of Flanders, among Catholics, among women who didn't work outside the home, and among those in higher income groups. Belgium has a relatively high infant mortality rate. 80% of the infant deaths in Belgium are perinatal in nature, due mainly to sociocultural and socio-hygienic factors. Trends in fertility and mortality have led to an increase in the average age of the Belgian population, which could lead to future socioeconomic problems. Social and economic incentives for having children should be instituted in order to secure the stability of the Belgian population, without infringing on the freedom of women to choose to work and have children. This would include aid for families in which both parents work, and economic aid so that those families in which the woman remains at home can afford to have more children. It is recommended that 30-35% of Belgian families should have 3 children instead of 2, if socioeconomic stability is to be achieved.

Objective Infants from multiple pregnancies have higher rates of preterm birth, stillbirth and neonatal death and differences in multiple birth rates (MBR) exist between countries. We aimed to describe differences in MBR in Europe and to investigate the impact of these differences on adverse perinatal outcomes at a population level. Methods We used national aggregate birth data on multiple pregnancies, maternal age, gestational age (GA), stillbirth and neonatal death collected in the Euro-Peristat project (29 countries in 2010, N = 5 074 643 births). We also used European Society of Human Reproduction and Embryology (ESHRE) data on assisted conception and single embryo transfer (SET). The impact of MBR on outcomes was studied using meta-analysis techniques with random-effects models to derive pooled risk ratios (pRR) overall and for four groups of country defined by their MBR. We computed population attributable risks (PAR) for these groups. Results In 2010, the average MBR was 16.8 per 1000 women giving birth, ranging from 9.1 (Romania) to 26.5 (Cyprus). Compared to singletons, multiples had a nine-fold increased risk (pRR 9.4, 95% Cl 9.1–9.8) of preterm birth (<37 weeks GA), an almost 12-fold increased risk (pRR 11.7, 95% CI 11.0–12.4) of very preterm birth (<32 weeks GA). Pooled RR were 2.4 (95% Cl 1.5–3.6) for fetal mortality at or after 28 weeks GA and 7.0 (95% Cl 6.1–8.0) for neonatal mortality. PAR of neonatal death and very preterm birth were higher in countries with high MBR compared to low MBR (17.1% (95% CI 13.8–20.2) versus 9.8% (95% Cl 9.6–11.0) for neonatal death and 29.6% (96% CI 28.5–30.6) versus 17.5% (95% CI 15.7–18.3) for very preterm births, respectively). Conclusions Wide variations in MBR and their impact on population outcomes imply that efforts by countries to reduce MBR could improve perinatal outcomes, enabling better long-term child health.

Post-term pregnancy is an important factor in perinatal mortality and morbidity. Generally, to reduce perinatal mortality in pregnancy, the delivery is done before adverse perinatal morbidity occurs. To prevent prolonged pregnancy, labor is induced with chemical drugs and complementary therapies. Due to the side effects and contraindications of chemical medicine, the use of herbs has been investigated in the induction of labor in post-term pregnancy. This study was done to identify the effect of chamomile on inducing labor in women with post-term pregnancy of Shahid Akbarabadi hospital in Tehran in 2013. This double-blind clinical trial study was performed in Iran on 80 post-term pregnant women with a gestational age of 40 weeks or more, a single pregnancy, 18 - 35 years old, cephalic presentation, an estimated fetal weight of 2500 - 4000 grams, an absence of uterine contraction, a cervical Bishop score of less than 4, the safety of the membrane, and low-risk pregnancy; they were randomly assigned to one of two groups of 40 women. Each of the participants was given a bottle containing 42 capsules (500 mg each) and took 2 capsules every 8 hours. The data were collected through the questionnaire of demographic observational, and examinal characteristics. Descriptive statistics, independent samples t-test, and Fisher's exact test using SPSS (16/win) were used to determine and compare the effects of drugs on inducing labor in the groups. After a week of using the first dose, the results showed that in 92.5% of the chamomile group and 62.5% in the placebo group, delivery symptoms started after taking the oral capsules, and there were significant statistical differences between the two groups for the onset of labor (P = 0.003) There was a noticeable statistical difference between the two groups regarding the mean interval time to the onset of labor pain after taking the capsules (P = 0.000). In this study¸ chamomile stimulated labor in post-term pregnancy. With further studies, chamomile, which has no chemical side effects, can be suggested for stimulating labor in post-term pregnancy.

Auditing stillbirths at Lower Umfolozi War Memorial Regional Hospital: A 12-month review.

Although the total number of stillbirths worldwide was estimated at 2.6 million in 2009, there is currently a dearth of literature on stillbirths in developing countries and rural settings, where the majority of such births occur. The 'Hands Up' Mortality and Morbidity Extraction Tool (HUMMET), developed at Lower Umfolozi War Memorial Regional Hospital (LUWMRH) in 2010, outlines a systematic approach to summarising individual cases of adverse perinatal outcomes. To depict the HUMMET form by describing the detailed demographic and obstetric profile of patients who delivered a stillborn infant at LUWMRH, as well as risk factors associated with these stillbirths between 1 April 2014 and 31 March 2015. The findings add to a global initiative advanced by the Lancet series on stillbirths, aimed at raising awareness of stillbirth statistics in low- and middle-income countries. A total of 310 detailed stillbirth case summaries of 305 patients were collected during the study period, representing 90% of the total number of stillborn infants delivered at LUWMRH. A retrospective audit of the HUMMET forms was conducted and the cases were further summarised in a Microsoft Excel spreadsheet that allowed for a univariate analysis of the variables. The stillbirth rate at LUWMRH is much higher than that at other regional hospitals owing to the number of at-risk referrals and emergency cases from surrounding clinics and district hospitals. Referrals were from local clinics (49%) and district hospitals (45%), 35% of stillbirths were due to abruptio placentae and a large proportion were associated with gestational hypertension, pre-eclampsia and/or eclampsia. Avoidable factors were predominantly a late patient response to reduced fetal movements and delays in transfer to hospital. Twenty percent of stillbirths were associated with inappropriate monitoring or management of the obstetric condition at the district hospital. The HUMMET form provides a systematic approach to analysing cases of perinatal morbidity and mortality in line with the requirements of the Perinatal Problem Identification Programme database, but provides more details on the circumstances and contributing factors. A repeat audit is recommended to determine whether interventions have been effective.

Global mortality, disability, and the contribution of risk factors: Global Burden of Disease Study.

Prevention and control of disease and injury require information about the leading medical causes of illness and exposures or risk factors. The assessment of the public-health importance of these has been hampered by the lack of common methods to investigate the overall, worldwide burden. The Global Burden of Disease Study (GBD) provides a standardised approach to epidemiological assessment and uses a standard unit, the disability-adjusted life year (DALY), to aid comparisons. DALYs for each age-sex group in each GBD region for 107 disorders were calculated, based on the estimates of mortality by cause, incidence, average age of onset, duration, and disability severity. Estimates of the burden and prevalence of exposure in different regions of disorders attributable to malnutrition, poor water supply, sanitation and personal and domestic hygiene, unsafe sex, tobacco use, alcohol, occupation, hypertension, physical inactivity, use of illicit drugs, and air pollution were developed. Developed regions account for 11.6% of the worldwide burden from all causes of death and disability, and account for 90.2% of health expenditure worldwide. Communicable, maternal, perinatal, and nutritional disorders explain 43.9%; non-communicable causes 40.9%; injuries 15.1%; malignant neoplasms 5.1%; neuropsychiatric conditions 10.5%; and cardiovascular conditions 9.7% of DALYs worldwide. The ten leading specific causes of global DALYs are, in descending order, lower respiratory infections, diarrhoeal diseases, perinatal disorders, unipolar major depression, ischaemic heart disease, cerebrovascular disease, tuberculosis, measles, road-traffic accidents, and congenital anomalies. 15.9% of DALYs worldwide are attributable to childhood malnutrition and 6.8% to poor water, and sanitation and personal and domestic hygiene. The three leading contributors to the burden of disease are communicable and perinatal disorders affecting children. The substantial burdens of neuropsychiatric disorders and injuries are under-recognised. The epidemiological transition in terms of DALYs has progressed substantially in China, Latin America and the Caribbean, other Asia and islands, and the middle eastern crescent. If the burdens of disability and death are taken into account, our list differs substantially from other lists of the leading causes of death. DALYs provide a common metric to aid meaningful comparison of the burden of risk factors, diseases, and injuries.

Objectives We aimed to assess the prevalence of uterine rupture in Belgium and to evaluate risk factors, management and outcomes for mother and child. Design Nationwide population-based prospective cohort study. Setting Emergency obstetric care. Participation of 97% of maternity units covering 98.6% of the deliveries in Belgium. Participants All women with uterine rupture in Belgium between January 2012 and December 2013. 8 women were excluded because data collection forms were not returned. Results Data on 90 cases of confirmed uterine rupture were obtained, of which 73 had a previous Caesarean section (CS), representing an estimated prevalence of 3.6 (95% CI 2.9 to 4.4) per 10 000 deliveries overall and of 27 (95% CI 21 to 33) and 0.7 (95% CI 0.4 to 1.2) per 10 000 deliveries in women with and without previous CS, respectively. Rupture occurred during trial of labour after caesarean section (TOLAC) in 57 women (81.4%, 95% CI 68% to 88%), with a high rate of augmented (38.5%) and induced (29.8%) labour. All patients who underwent induction of labour had an unfavourable cervix at start of induction (Bishop Score ≤7 in 100%). Other uterine surgery was reported in the history of 22 cases (24%, 95% CI 17% to 34%), including 1 case of myomectomy, 3 cases of salpingectomy and 2 cases of hysteroscopic resection of a uterine septum. 14 cases ruptured in the absence of labour (15.6%, 95% CI 9.5% to 24.7%). No mothers died; 8 required hysterectomy (8.9%, 95% CI 4.6% to 16.6%). There were 10 perinatal deaths (perinatal mortality rate 117/1000 births, 95% CI 60 to 203) and perinatal asphyxia was observed in 29 infants (34.5%, 95% CI 25.2% to 45.1%). Conclusions The prevalence of uterine rupture in Belgium is similar to that in other Western countries. There is scope for improvement through the implementation of nationally adopted guidelines on TOLAC, to prevent use of unsafe procedures, and thereby reduce avoidable morbidity and mortality.

Introduction L’objectif était d’analyser les facteurs de risque de mortalité maternelle et périnatale de la césarienne à Lubumbashi, République Démocratique du Congo (RDC). Méthodes Étude multicentrique de 3643 césariennes réalisées entre le 1er janvier 2009 et le 31 décembre 2013 sur un total de 34199 accouchements dans cinq formations hospitalières de référence à Lubumbashi (RDC). Les données sociodémographiques, les indications, l’environnement obstétrical et la morbi-mortalité maternelles et périnatales ont été analysés au logiciel Epi Info 2011. Les fréquences calculées sont exprimées en pourcentage et les moyennes avec leurs écart-types. Le test de Chi-carré et le test exact de Fisher lorsque recommandés ont été utilisés pour la comparaison des fréquences. L’odds ratio a été calculé avec l’intervalle de confiance de 95% de Cornfield grâce à un modèle de régression logistique pour déterminer la puissance de facteurs de risque. Le seuil de signification a été fixé à p < 0,05. Résultats La fréquence de la césarienne était de 10,65%. L'âge moyen des césarisées était de 28,83±6,8 ans (extrêmes: 14 et 49 ans). La parité variait de 1 à 16 avec une moyenne de 2,6. De ces opérées, une sur neuf (10,9%) était porteuse d’un utérus cicatriciel de césarienne antérieure et 22,3% étaient des évacuées obstétricales. Les taux de létalité maternelle et périnatale étaient respectivement de 1,4% et 7,07% lors de la césarienne. L’analyse des facteurs de risque montre que la grande multiparité (≥5), l’absence de surveillance de la grossesse, le caractère urgent de l’indication opératoire influent significativement sur la mortalité maternelle. A ces facteurs s’ajoutent pour la mortalité périnatale l’âge maternel avancé (> 35 ans), l’évacuation comme mode d’admission et l’immaturité fœtale. Conclusion Cette étude montre que la césarienne dans nos conditions de travail est couplée à une forte mortalité maternelle et périnatale. Les facteurs de risque identifiés sont en grande partie évitables, surtout à tort ou à raison imputés à l’opération masquant ipso facto les circonstances souvent irrationnelles de sa pratique. Introduction The objective was to analyze risk factors for maternal and perinatal mortality among women undergoing cesarean section in Lubumbashi, Democratic Republic of Congo (DRC). Methods We conducted a multicenter study of 3643 women undergoing cesarean sections between 1 January 2009 and 31 December 2013 out of 34199 women delivering in five general referral hospitals in Lubumbashi (DRC). Sociodemographic data, indications, obstetrical environment as well as maternal and perinatal morbi-mortality were analyzed using Epi Info 2011 software. Computed frequencies were expressed in percentage and mean values were expressed in terms of standard deviations. Chi-square test and Fisher’s exact test, when recommended, were used to compare frequencies. The odds ratio was calculated using Cornfield 95% confidence interval based on a logistic regression model in order to determine the strength of risk factors. Threshold significance level was set at p < 0.05. Results The frequency of cesarean sections was 10.65%. The average age of women undergoing cesarean section was 28.83 ± 6.8 years (with a range from 14 to 49 years). Parity ranged from 1 to 16 with an average of 2.6. 1 out of 9 (10.9%) women undergoing cesarean section were patients with previous caesarean section uterine scar on the anterior wall of the uterus and 22.3% of women were patients with previous obstetric evaquation. Maternal and perinatal mortality rate was 1.4% and 7.07% during cesarean section respectively. The analysis of risk factors shows that the great multiparity (≥5), the absence of monitoring during pregnancy, the urgent nature of emergency surgery significantly affect maternal mortality. Other factors for perinatal mortality included advanced maternal age (>35 years), patients referral from one facility to another as a mode of admission and fetal immaturity. Conclusion This study shows that cesarean section in our working condition is associated to a significant maternal and perinatal mortality. Identified risk factors are largely preventable, because they are rightly or wrongly ascribed to cesarean section glossing over, ipso facto, the often irrational circumstances of its practice.

Unusually cold and dry winters increase mortality in Australia.

Seasonal patterns in mortality have been recognised for decades, with a marked excess of deaths in winter, yet our understanding of the causes of this phenomenon is not yet complete. Research has shown that low and high temperatures are associated with increased mortality independently of season; however, the impact of unseasonal weather on mortality has been less studied. In this study, we aimed to determine if unseasonal patterns in weather were associated with unseasonal patterns in mortality. We obtained daily temperature, humidity and mortality data from 1988 to 2009 for five major Australian cities with a range of climates. We split the seasonal patterns in temperature, humidity and mortality into their stationary and non-stationary parts. A stationary seasonal pattern is consistent from year-to-year, and a non-stationary pattern varies from year-to-year. We used Poisson regression to investigate associations between unseasonal weather and an unusual number of deaths. We found that deaths rates in Australia were 20-30% higher in winter than summer. The seasonal pattern of mortality was non-stationary, with much larger peaks in some winters. Winters that were colder or drier than a typical winter had significantly increased death risks in most cities. Conversely summers that were warmer or more humid than average showed no increase in death risks. Better understanding the occurrence and cause of seasonal variations in mortality will help with disease prevention and save lives. Copyright © 2014 Elsevier Inc. All rights reserved.

In this paper we describe health and morbidity characteristics of Bedouin women in southern Israel, based on papers published over the past 20 years. This is a unique population whose customs, tradition, singular circumstances as a population "in transit", and underprivileged socio-economic status are reflected in mental illness, pregnancy course, perinatal morbidity and mortality rates, and acute and chronic disease. Recognition of these characteristics can help the medical team treat various health problems in this population as well as other populations with similar characteristics.

Psychosocial stress in pregnancy and its relation to the onset of premature labour.

A modified life events inventory was presented over a four-month period to 132 consecutive women going into spontaneous labour in Hull and Manchester. Three study groups were identified according to the duration of pregnancy. The levels of psychosocial stress in pregnancy were found to be particularly high in the mothers whose babies were born preterm. Stressful events may precipitate preterm labour in some women. The concept of antenatal care may have to be broadened if the incidence of premature labour and resulting perinatal mortality are to be reduced.

Best Practice Guidelines for Monitoring Socioeconomic Inequalities in Health Status: Lessons from Scotland

PubMed Central

Frank, John; Haw, Sally

2011-01-01

Context In this article we present “best practice” guidelines for monitoring socioeconomic inequalities in health status in the general population, using routinely collected data. Methods First, we constructed a set of critical appraisal criteria to assess the utility of routinely collected outcomes for monitoring socioeconomic inequalities in population health status, using epidemiological principles to measure health status and quantify health inequalities. We then selected as case studies three recent “cutting-edge” reports on health inequalities from the Scottish government and assessed the extent to which each of the following outcomes met our critical appraisal criteria: natality (low birth weight rate, LBW), adult mortality (all-cause, coronary heart disease [CHD], alcohol-related, cancer, and healthy life expectancy at birth), cancer incidence, and mental health and well-being. Findings The critical appraisal criteria we derived were “completeness and accuracy of reporting”; “reversibility and sensitivity to intervention”; “avoidance of reverse causation”; and “statistical appropriateness.” Of these, the most commonly unmet criterion across the routinely collected outcomes was “reversibility and sensitivity to intervention.” The reasons were that most mortality events occur in later life and that the LBW rate has now become obsolete as a sole indicator of perinatal health. Other outcomes were also judged to fail other criteria, notably alcohol-related mortality after midlife (“avoidance of reverse causation”); all cancer sites’ incidence and mortality (statistical appropriateness due largely to heterogeneity of SEP gradients across different cancer sites, as well as long latency); and mental health and well-being (“uncertain reversibility and sensitivity to intervention”). Conclusions We conclude that even state-of-the-art data reports on health inequalities by SEP have only limited usefulness for most health and social policymakers because they focus on routinely collected outcomes that are not very sensitive to intervention. We argue that more “upstream” outcome measures are required, which occur earlier in the life course, can be changed within a half decade by feasible programs and policies of proven effectiveness, accurately reflect individuals’ future life-course chances and health status, and are strongly patterned by SEP.

ABSTRACT OBJECTIVE Analyze the trend of infant mortality in Rio Branco, state of Acre, from 1999 to 2015. METHODS An ecological observational study of a time series, in which data from deaths from the Information System on Mortality and Births of the Information System on Live Births were used. The annual percentage change was estimated using the Joinpoint software. RESULTS The infant mortality rate decreased from 26.99 in 1999 to 14.50 in 2015 per 1,000 live births, with an annual percentage change of -4.37 (95%CI -5.4– -3.4). When stratified by age components, the neonatal period presented an annual percentage change of -4.73 (95%CI -5.7– -3.7), and the post-neonatal period was -3.7 (95%CI -5.4– -2.0). Avoidability, avoidable causes and poorly defined causes showed a downward trend throughout the period and causes not clearly preventable showed an upward trend until 2008. The group of causes that contributed most to the infant deaths during the period studied was perinatal diseases, followed by malformations, infectious and parasitic diseases, and respiratory diseases. CONCLUSIONS Despite the decreasing trend in infant mortality rates in the capital compared to developed countries, it is relatively high. PMID:29641657

Background Screening and monitoring in pregnancy are strategies used by healthcare providers to identify high-risk pregnancies so that they can provide more targeted and appropriate treatment and follow-up care, and to monitor fetal well-being in both low- and high-risk pregnancies. The use of many of these techniques is controversial and their ability to detect fetal compromise often unknown. Theoretically, appropriate management of maternal and fetal risk factors and complications that are detected in pregnancy and labour could prevent a large proportion of the world's 3.2 million estimated annual stillbirths, as well as minimise maternal and neonatal morbidity and mortality. Methods The fourth in a series of papers assessing the evidence base for prevention of stillbirths, this paper reviews available published evidence for the impact of 14 screening and monitoring interventions in pregnancy on stillbirth, including identification and management of high-risk pregnancies, advanced monitoring techniques, and monitoring of labour. Using broad and specific strategies to search PubMed and the Cochrane Library, we identified 221 relevant reviews and studies testing screening and monitoring interventions during the antenatal and intrapartum periods and reporting stillbirth or perinatal mortality as an outcome. Results We found a dearth of rigorous evidence of direct impact of any of these screening procedures and interventions on stillbirth incidence. Observational studies testing some interventions, including fetal movement monitoring and Doppler monitoring, showed some evidence of impact on stillbirths in selected high-risk populations, but require larger rigourous trials to confirm impact. Other interventions, such as amniotic fluid assessment for oligohydramnios, appear predictive of stillbirth risk, but studies are lacking which assess the impact on perinatal mortality of subsequent intervention based on test findings. Few rigorous studies of cardiotocography have reported stillbirth outcomes, but steep declines in stillbirth rates have been observed in high-income settings such as the U.S., where cardiotocography is used in conjunction with Caesarean section for fetal distress. Conclusion There are numerous research gaps and large, adequately controlled trials are still needed for most of the interventions we considered. The impact of monitoring interventions on stillbirth relies on use of effective and timely intervention should problems be detected. Numerous studies indicated that positive tests were associated with increased perinatal mortality, but while some tests had good sensitivity in detecting distress, false-positive rates were high for most tests, and questions remain about optimal timing, frequency, and implications of testing. Few studies included assessments of impact of subsequent intervention needed before recommending particular monitoring strategies as a means to decrease stillbirth incidence. In high-income countries such as the US, observational evidence suggests that widespread use of cardiotocography with Caesarean section for fetal distress has led to significant declines in stillbirth rates. Efforts to increase availability of Caesarean section in low-/middle-income countries should be coupled with intrapartum monitoring technologies where resources and provider skills permit.

To examine how the relaxation of the one child policy and policies to reduce caesarean section rates might have affected trends over time in caesarean section rates and perinatal and pregnancy related mortality in China. Observational study. China's National Maternal Near Miss Surveillance System (NMNMSS). 6 838 582 births at 28 completed weeks or more of gestation or birth weight ≥1000 g in 438 hospitals in the NMNMSS between 2012 and 2016. Obstetric risk was defined using a modified Robson classification. The main outcome measures were changes in parity and age distributions and relative frequency of each Robson group, crude and adjusted trends over time in caesarean section rates within each risk category (using Poisson regression with a robust variance estimator), and trends in perinatal and pregnancy related mortality over time. Caesarean section rates declined steadily between 2012 and 2016 (crude relative risk 0.91, 95% confidence interval 0.89 to 0.93), reaching an overall hospital based rate of 41.1% in 2016. The relaxation of the one child policy was associated with an increase in the proportion of multiparous births (from 34.1% in 2012 to 46.7% in 2016), and births in women with a uterine scar nearly doubled (from 9.8% to 17.7% of all births). Taking account of these changes, the decline in caesarean sections was amplified over time (adjusted relative risk 0.82, 95% confidence interval 0.81 to 0.84). Caesarean sections declined noticeably in nulliparous women (0.75, 0.73 to 0.77) but also declined in multiparous women without a uterine scar (0.65, 0.62 to 0.77). The decrease in caesarean section rates was most pronounced in hospitals with the highest rates in 2012, consistent with the government's policy of targeting hospitals with the highest rates. Perinatal mortality declined from 10.1 to 7.2 per 1000 births over the same period (0.87, 0.83 to 0.91), and there was no change in pregnancy related mortality over time. China is the only country that has succeeded in reverting the rising trends in caesarean sections. China's success is remarkable given that the changes in obstetric risk associated with the relaxation of the one child policy would have led to an increase in the need for caesarean sections. China's experience suggests that change is possible when strategies are comprehensive and deal with the system level factors that underpin overuse as well as the various incentives at work during a clinical encounter.

Defining dietary guidelines requires a quantitative assessment of the influence of diet on the development of diseases. The aim of the study was to investigate how dietary patterns were associated with mortality in a general population sample of Switzerland. We included 15,936 participants from two population-based studies (National Research Program 1A (NRP1A) and Monitoring of Trends and Determinants in Cardiovascular Disease (MONICA)—1977 to 1993) who fully answered a simplified 24-h dietary recall. Mortality data were available through anonymous record linkage with the Swiss National Cohort (follow-up of up to 37.9 years). Multiple correspondence analysis and hierarchical clustering were used to define data-driven qualitative dietary patterns. Mortality hazard ratios were calculated for all-cause, cancer and cardiovascular mortality using Cox regression. Two patterns were characterized by a low dietary variety (“Sausage and Vegetables”, “Meat and Salad”), two by a higher variety (“Traditional”, “High-fiber foods”) and one by a high fish intake (“Fish”). Males with unhealthy lifestyle (smokers, low physical activity and high alcohol intake) were overrepresented in the low-variety patterns and underrepresented in the high-variety and “Fish” patterns. In multivariable-adjusted models, the “Fish” (hazard ratio = 0.82, 95% CI (0.68–0.99)) and “High-fiber foods” (0.85 (0.72–1.00)) patterns were associated with lower cancer mortality. In men, the “Fish” (0.73 (0.55–0.97)) and “Traditional” (0.76 (0.59–0.98)) patterns were associated with lower cardiovascular mortality. In summary, our results support the notion that dietary patterns affect mortality and that these patterns strongly cluster with other health determinants. PMID:29518908

This study aims at determining the prevalence of neonatal hypoglycemia and its underlying causes. In this prospective study 14168 newborns delivered in Tabriz Alzahra Hospital during 2 years were evaluated in regard to blood glucose level at first 24 h of life. Glucose oxidase method with 4-aminophenazone with a Greiner G-300 was the used method for determining the blood glucose level. Cases with blood glucose < 50 mg dL(-1) were considered as hypoglycemic newborns. Underlying causes of this condition, as well as the short-term mortality rate were determined. Prevalence of neonatal hypoglycemia was 0.4% (52 newborns). Underlying causes of hypoglycemia were prematurity (61.5%), diabetic mother (13.6%), septicemia (9.6%), perinatal asphyxia (9.6%), stress (3.8%) and neonatal hyperinsulinism (1.9%). The mortality rate was 53.8%, with prematurity as the leading cause of death.

maternal and perinatal morbidity and mortality rates in Cambodia are high. The provision of quality care by skilled birth attendants (SBAs) in a supportive working environment is an important strategy to reduce morbidity and mortality. There has been little emphasis on examining this issue in Cambodia. The objective of this study was to establish SBA reported practices during labour, birth and the immediate postpartum periods and the factors affecting this. a descriptive qualitative design was employed using in-depth interviews and focus group discussions with midwives, nurses and doctors with midwifery skills in two health centres and three referral hospitals in one province of Cambodia. Data were analysed using a thematic framework. SBA practice is not always consistent with evidence-based standards known to reduce morbidity and mortality. Ten inter-related themes emerged, which described patterns of SBA practice, were identified. These were: skills in the care of labouring women; provision of support in labour; interventions in the second stage of labour; management of the third stage of labour; cleanliness during birth; immediate care of the newborn infant and immediate postnatal care; lack of policy and authority; fear of litigation; workload and lack of human resources; and financial incentives and socio-economic influences. a gap exists between evidence-based standards and current SBA practice during labour, birth and the immediate postpartum care. This is largely driven by the lack of a supportive working environment. the findings of this research provide maternal health services, workforce planners and policy makers with valuable information to contribute to the continuous quality improvement of maternity care. The findings highlight implications for practice that may improve the quality of maternal health care. Recommendations for decision makers were made and further research is needed in order to develop theories and recommendations to improve SBA practice in Cambodia, to the benefit of the Cambodia women and newborn babies.

Factors Regulating Vagal Sensory Development: Potential Role in Obesities of Developmental Origin

Contributors to increased obesity in children may include perinatal under- or overnutrition. Humans and rodents raised under these conditions develop obesity, which like obesities of other etiologies has been associated with increased meal size. Since vagal sensory innervation of the gastrointestinal (GI) tract transmits satiation signals that regulate meal size, one mechanism through which abnormal perinatal nutrition could increase meal size is by altering vagal development, possibly by causing changes in the expression of factors that control it. Therefore, we have begun to characterize development of vagal innervation of the GI tract and the expression patterns and functions of the genes involved in this process. Important events in development of mouse vagal GI innervation occurred between midgestation and the second postnatal week, suggesting they could be vulnerable to effects of abnormal nutrition preor postnatally. One gene investigated was brain- derived neurotrophic factor (BDNF), which regulates survival of a subpopulation of vagal sensory neurons. BDNF was expressed in some developing stomach wall tissues innervated by vagal afferents. At birth, mice deficient in BDNF exhibited a 50% reduction of putative intraganglionic laminar ending mechanoreceptor precursors, and a 50% increase in axons that had exited fiber bundles. Additionally, BDNF was required for patterning of individual axons and fiber bundles in the antrum and differentiation of intramuscular array mechanoreceptors in the forestomach. It will be important to determine whether abnormal perinatal environments alter development of vagal sensory innervation of the GI tract, involving effects on expression of BDNF, or other factors regulating vagal development.

Evolution of aging: individual life history trade-offs and population heterogeneity account for mortality patterns across species.

A broad range of mortality patterns has been documented across species, some even including decreasing mortality over age. Whether there exist a common denominator to explain both similarities and differences in these mortality patterns remains an open question. The disposable soma theory, an evolutionary theory of aging, proposes that universal intracellular trade-offs between maintenance/lifespan and reproduction would drive aging across species. The disposable soma theory has provided numerous insights concerning aging processes in single individuals. Yet, which specific population mortality patterns it can lead to is still largely unexplored. In this article, we propose a model exploring the mortality patterns which emerge from an evolutionary process including only the disposable soma theory core principles. We adapt a well-known model of genomic evolution to show that mortality curves producing a kink or mid-life plateaus derive from a common minimal evolutionary framework. These mortality shapes qualitatively correspond to those of Drosophila melanogaster, Caenorhabditis elegans, medflies, yeasts and humans. Species evolved in silico especially differ in their population diversity of maintenance strategies, which itself emerges as an adaptation to the environment over generations. Based on this integrative framework, we also derive predictions and interpretations concerning the effects of diet changes and heat-shock treatments on mortality patterns. © 2014 The Authors.

Placental calcification is associated with an increased risk of perinatal morbidity and mortality. The subjectivity of current ultrasound methods of assessment of placental calcification indicates that a more objective method is required. The aim of this study was to correlate the percentage of calcification defined by the clinician using a new software tool for calculating the extent of placental calcification with traditional ultrasound methods and with pregnancy outcome. Ninety placental images were individually assessed. An upper threshold was defined, based on high intensity, to quantify calcification within the placenta. Output metrics were then produced including the overall percentage of calcification with respect to the total number of pixels within the region of interest. The results were correlated with traditional ultrasound methods of assessment of placental calcification and with pregnancy outcome. The results demonstrate a significant correlation between placental calcification, as defined using the software, and traditional methods of Grannum grading of placental calcification. Whilst correlation with perinatal outcome and cord pH was not significant as a result of small numbers, patients with placental calcification assessed using the computerized software at the upper quartile had higher rates of poor perinatal outcome when compared with those at the lower quartile (8/22 (36%) vs 3/23 (13%); P = 0.069). These results suggest that this computerized software tool has the potential to become an alternative method of assessing placental calcification. Copyright © 2012 ISUOG.

Severe preeclampsia is a disorder of pregnancy characterized by high blood pressure and significant proteinuria after 20 weeks gestation. Severe preeclampsia and eclampsia have considerable adverse impacts on maternal, fetal, and neonatal health especially in low-resource countries. Hypertensive disorders of pregnancy are the third leading cause of maternal deaths in Sub-Saharan Africa. Significant avoidable maternal and neonatal morbidity and mortality may result. This study aimed 1) to determine the incidence of severe preeclampsia/eclampsia in a low-resource setting; 2) to determine the maternal complications of severe preeclampsia/eclampsia in a low-resource setting; 3) to determine the perinatal outcomes of severe preeclampsia/eclampsia in a low-resource setting. This was a retrospective descriptive cohort study carried out at Mpilo Central Hospital, a tertiary teaching referral government hospital in a low-resource setting in Bulawayo, Zimbabwe. Data were obtained from the birth registers in labor ward, intensive care unit, and neonatal intensive care unit of patients who had a diagnosis of severe preeclampsia or eclampsia for the period January 1, 2016, to December 31, 2016. The case notes were retrieved and the demographic, clinical, and outcome data were gathered. There were 9,086 deliveries at the institution during the period January 1, 2016, to December 31, 2016. There were 121 cases of severe preeclampsia/eclampsia. The incidence of severe preeclampsia/eclampsia was 1.3% at Mpilo Central Hospital. The most common major complication was HELLP syndrome (9.1%). Maternal mortality was 1.7%. There were 127 babies born with six sets of twins, 49.6% of the babies were lost through stillbirths and early neonatal deaths. The incidence of severe preeclampsia/eclampsia at Mpilo Central Hospital was 1.3%. The most common maternal complication was hemolysis elevated liver enzymes low platelet syndrome. Maternal mortality was 1.7% due to acute renal failure. Nearly half (49.6%) of the babies born were lost to stillbirths and early neonatal deaths.

Objectives. We examined association between incidence rate of low birth weight in liveborn infants and maternal sociodemographic status in Tuzla Canton during 1992–1995 war in Bosnia and Herzegovina. Methods. The present study covers a 22-year period (1988–2009), including the war period (1992–1995), and we retrospectively collected data on a total of 108 316 liveborn infants and their mothers from three different socioeconomic periods: before (1988–1991), during (1992–1995), and after the war (1996–2009). Association between incidence rate of low birth weight in liveborn infants and maternal sociodemographic status were determined for each study period. Results. There were 23 194 live births in the prewar, 18 302 during the war, and 66 820 in the postwar period. Among the liveborn infants born during the war, 1373 (7.5%) had birth weight of <2500 g, which is significantly more in comparison with 851 (3.6%) liveborn infants in this birth weight group born before and 1864 (2.8%) after the war. We found the number of examinations during pregnancy was 1.8 per pregnant woman in the war period, which was low in comparison with the number of examinations before (4.6 per pregnant woman) and after (7.1 per pregnant woman) the war (P<.001 for both). Prewar perinatal mortality LBW infants of 6.2 per 1000 live births increased to 10.8 per 1000 live births during the war (P<.001), but after the war, perinatal mortality LBW infants (5.2‰) and early neonatal mortality (2.4‰) decreased. Conclusions. We found statistically significant association between low-birth-weight and maternal sociodemographic status in Tuzla Canton during 1992–1995 war in Bosnia and Herzegovina. PMID:21490700
