Abstract
BACKGROUND Advanced maternal-age pregnancy has become a serious public health problem in both developed and developing countries due to adverse birth outcomes for the mother, fetus, or newborn. However, there are limited studies conducted to identify determinants of advanced-age pregnancy in Ethiopia. Therefore, this study aimed to assess individual and community-level determinants of advanced age pregnancy in Ethiopia. METHODS This study was based on 2016 Ethiopian Demographic and Health Survey data. Three thousand two hundred ninety-two weighted samples of pregnant women were included in this analysis. A multilevel logistic regression model was conducted to assess the determinants of advanced-age pregnancy among the study participants in Ethiopia. RESULTS maternal age at first birth (AOR = 4.05, 95% CI: 1.77-9.22), level of maternal education [primary education 2.72 times (AOR = 2.27, 95 CI: 1.55-4.76) and secondary and above education (AOR = 5.65, 95% CI: 1.77-17.70)], having a history of alcohol (AOR = 11.8, 95% CI: 5.71-24.42), parity (AOR = 3.22, 95% CI: 2.69-3.84), number of household member (AOR = 1.22, 95% CI: 1.05-1.41), family planning unmet need for spacing of pregnancy (AOR = 4.79, 95% CI: 2.63-8.74), having sons/daughters elsewhere (AOR = 1.89, 95% CI: 1.22-2.94), had higher community poverty level (AOR = 2.37, 95% CI: 1.16-4.85), those had higher community unmet need for family planning (AOR = 5.19, 95% CI: 2.72-9.92) were more likely to have advanced age pregnancy. Whereas Living in an Emerging region (AOR = 0.29, 95% CI: 0.14-0.59) and living in a metropolitan city (AOR = 0.03, 95% CI: 0.03-0.38), were less likely to have advanced age pregnancy. CONCLUSIONS increased Maternal age at first birth, level of maternal education, history of alcohol drinking, increased number of parity and household members, family planning unmet need for spacing, had sons/daughters elsewhere, had higher community poverty level, those had higher community unmet need for family planning positively, whereas living in the emerging region and living in metropolitan's city was negatively affect advanced age pregnancy. Help women to have informed decision-making and create platforms to women have special care during this age of pregnancy. Empower women on family planning and socioeconomic status.

Abstract
INTRODUCTION Perinatal mortality remains a pressing concern, especially in lower and middle-income nations. Globally, 1 in 72 babies are stillborn. Despite advancements, the 2030 targets are challenging, notably in sub-Saharan Africa. Post-war Liberia saw a 14% spike in perinatal mortality between 2013 and 2020, indicating the urgency for in-depth study. OBJECTIVE The study aims to investigate the predictors of perinatal mortality in Liberia using 2013 and 2019-2020 Liberia Demographic and Health Survey datasets. METHODS In a two-stage cluster design from the Liberia Demographic and Health Survey, 6572 and 5285 respondents were analysed for 2013 and 2019-2020, respectively. Data included women aged 15-49 with pregnancy histories. Descriptive statistics was used to analyse the sociodemographic characteristics, the exposure to media and the maternal health services. Bivariate and multivariate logistic regressions were used to examine the predictors of perinatal mortality at a significance level of p value ≤0.05 and 95% CI. The data analysis was conducted in STATA V.14. RESULTS Perinatal mortality rates increased from 30.23 per 1000 births in 2013 to 42.05 in 2019-2020. In 2013, increasing age of respondents showed a reduced risk of perinatal mortality rate. In both years, having one to three children significantly reduced mortality risk (2013: adjusted OR (aOR) 0.30, 95% CI 0.14 to 0.64; 2019: aOR 0.24, 95% CI 0.11 to 0.54), compared with not having a child. Weekly radio listenership increased mortality risk (2013: aOR 1.36, 95% CI 0.99 to 1.89; 2019: aOR 1.86, 95% CI 1.35 to 2.57) compared with not listening at all. Longer pregnancy intervals (p<0.0001) and receiving 2+ tetanus injections (p=0.019) were protective across both periods. However, iron supplementation showed varied effects, reducing risk in 2013 (aOR 0.90, 95% CI 0.48 to 1.68) but increasing it in 2019 (aOR 2.10, 95% CI 0.90 to 4.92). CONCLUSION The study reports an alarming increase in Liberia's perinatal mortality from 2013 to 2019-2020. The findings show dynamic risk factors necessitating adaptable healthcare approaches, particularly during antenatal care. These adaptable approaches are crucial for refining health strategies in line with the Sustainable Development Goals, with emphasis on the integration of health, education, gender equality, sustainable livelihoods and global partnerships for effective health outcomes.

Abstract
Centers for Disease Control and Prevention data from 2020 demonstrate the continued upward trend in the mean age of pregnant individuals in the United States. Observational studies demonstrate that pregnancy in older individuals is associated with increased risks of adverse pregnancy outcomes-for both the pregnant patient and the fetus-that might differ from those found in younger pregnant populations, even in healthy individuals with no other comorbidities. There are several studies that suggest that advancing age at the time of pregnancy is associated with greater disparities in severe maternal morbidity and mortality. This document seeks to provide evidence-based clinical recommendations for minimizing adverse outcomes associated with pregnancy with anticipated delivery at an advanced maternal age. The importance and benefits of accessible health care from prepregnancy through postpartum care for all pregnant individuals cannot be overstated. However, this document focuses on and addresses the unique differences in pregnancy-related care for women and all those seeking obstetrical care with anticipated delivery at the age of 35 years or older within the framework of routine pregnancy care. This Obstetric Care Consensus document was developed using an a priori protocol in conjunction with the authors listed above.

Abstract
OBJECTIVES In the current study, we aimed to evaluate the effect of advanced maternal age on perinatal outcomes in nulliparous singleton pregnancy. METHODS The perinatal outcome data of 11,366 patients who gave birth between 2015 and 2020 were evaluated retrospectively. Patients were subgrouped according to their age as control group (C) (20-29 years), late advanced maternal age group (30-34 years), advanced maternal age group (35-39 years), and very advanced maternal age group (≥40 years). Multinomial logistic regression analyses were performed to test the possible independent role of maternal age as a risk factor for adverse pregnancy outcomes. RESULTS Statistically significant difference was observed between the control group and the other groups in terms of preterm delivery, preeclampsia, gestational diabetes mellitus (GDM), small gestational age (SGA), large gestational age (LGA), premature rupture of membranes (PROM), high birth weight (HBW), and perinatal mortality rates (p<0.05). An increased risk of the need for neonatal intensive care unit (NICU) and perinatal mortality was observed in groups over 35 years old. CONCLUSIONS Age poses a risk in terms of preterm delivery, preeclampsia, LGA, GDM, and HBW in the groups over 30 years of maternal age. The rates of PROM, NICU, and perinatal mortality increase in addition to those perinatal results in the groups above 35 years of maternal age.

The trend in delayed childbearing and its potential consequences on pregnancy outcomes: a single center 9-years retrospective cohort study in Hubei, China. BMC Pregnancy Childbirth 2022; 22:514. [PMID: 35751047 PMCID: PMC9233367 DOI: 10.1186/s12884-022-04807-8] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Accepted: 06/02/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Due to the advancement of modern societies, the proportion of women who delay childbearing until or beyond 30 years has dramatically increased in the last three decades and has been linked with adverse maternal-neonatal outcomes. OBJECTIVE To determine the trend in delayed childbearing and its negative impact on pregnancy outcomes. MATERIAL AND METHODS A tertiary hospital-based retrospective study was conducted in Wuhan University Renmin Hospital, Hubei Province, China, during the years 2011-2019. The joinpoint regression analysis was used to find a trend in the delayed childbearing and the multiple binary logistic regression model was used to estimate the association between maternal age and pregnancy outcomes. RESULTS Between 2011 and 2019, the trend in advanced maternal age (AMA ≥35 years) increased by 75% [AAPC 7.5% (95% CI: - 10.3, 28.9)]. Based on maternal education and occupation, trend in AMA increased by 130% [AAPC 11.8% (95% CI: 1.1, 23.7)] in women of higher education level, and 112.5% [AAPC 10.1% (95% CI: 9.4, 10.9)] in women of professional services. After adjusting for confounding factors, AMA was significantly associated with increased risk of gestational hypertension (aOR 1.5; 95% CI: 1.2, 2.1), preeclampsia (aOR 1.6; 95% CI: 1.4, 1.9), sever preeclampsia (aOR 1.7; 95% CI: 1.1, 2.6), placenta previa (aOR 1.8; 95% CI: 1.5, 2.2), gestational diabetes mellitus (aOR 2.5; 95% CI: 2.3, 2.9), preterm births (aOR 1.6; 95% CI: 1.4, 1.7), perinatal mortality (aOR 1.8; 95% CI: 1.3, 2.3), and low birth weight (aOR 1.3; 95% CI: 1.2, 1.4) compared with women aged < 30 years. CONCLUSION Our findings show a marked increase in delayed childbearing and its negative association with pregnancy outcomes.

Abstract
OBJECTIVE To evaluate the risk levels for maternal and perinatal complications at >=40, >=45, >50 years old compared to younger controls METHODS: Electronic databases were searched from their inception until March 2021. We included studies reporting pregnancy outcome in pregnant women 40, 45 and 50 years or older compared with controls at the time of delivery. Case reports, and case series were excluded. The primary outcome was the incidence of stillbirth. Meta-analysis was performed using the random effects model of DerSimonian and Laird, to produce summary treatment effects in terms of either a relative risk (RR) with 95% confidence interval (CI). Heterogeneity was measured using I-squared (Higgins I2 ). Subgroup analyses in women older than 45 years and in those older than 50 years were performed. RESULTS 27 studies, including 31,090,631, were included in the meta-analysis. The overall quality of the included studies was moderate to high. The vast majority of the included studies were retrospective cohort studies (21/27), four were population-based studies, and two were cross sectional studies. Women ≥ 40 years had significantly higher risk of stillbirth (RR 2.16, 95% CI 1.86 to 2.51), perinatal mortality, IUGR, neonatal death, admission to NICU, preeclampsia, preterm delivery, cesarean delivery, and maternal mortality compared to <40 yo women (RR 3.18, 95% CI 1.68 to 5.98). The increased risk for maternal mortality was 42.76 and 11.60 for women older than 50 years and for those older than 45 years, respectively, while those for stillbirth was 3.72 and 2.32. The risk of stillbirth and cesarean delivery was significantly higher in women >45 years compared to those aged 40-45, and in those >50 years compared to those aged 45-50. The risk of maternal mortality was significantly higher in women >50 years compared to those aged 40-45 (RR 60.40, 95% CI 13.28 to 274.74). CONCLUSIONS The risk of stillbirth, cesarean delivery, and maternal mortality increases with advancing maternal age. The risk ratio for maternal mortality was 3.18, 11.60, and 42.76 in women older than 40, older than 45, and older than 50 years, respectively. These data should be used when women with advanced maternal age are counselled regarding their risk in pregnancy.

Abstract
This study aimed to identify differences in the trends of artificial and spontaneous fetal mortality rates between working and jobless households depending on ages, periods, and birth cohorts in Japan. Vital Statistics data from 1995 to 2019 and age groups in 5–year increments from 15 to 19 years through 45 to 49 years were used. Bayesian age–period–cohort analysis was used to evaluate changes in each of the outcomes. As a result, the difference in maternal age–standardized rate of both the artificial and spontaneous fetal mortality rates between the two types of households decreased in the periods analyzed. However, there was a statistically significant difference in the mortality rate between jobless and working households, regardless of maternal ages, periods, and cohorts for the artificial fetal mortality rate. A statistically significant difference was also observed for the spontaneous fetal mortality rates in some maternal ages, periods, and cohorts. In addition, the trend of birth cohort effects was particularly different between the two types of households for both the artificial and spontaneous fetal mortality rates.

Abstract
INTRODUCTION The age at which women give birth is rising steadily in the western world. Advanced maternal age has been associated with adverse pregnancy outcomes. We assessed the association between advanced maternal age and the risk of adverse maternal and perinatal outcome in primigravid and multigravid women. MATERIAL AND METHODS The study was a population-based cohort study and included women giving birth between January 2000 and December 2018 using data from the Dutch perinatal registration of Perined. Women were divided into age groups. We compared outcomes between women of 40-44, 45-49, and over 50 years old (the study groups) with women of 25-29 years old (reference group), stratified for parity. We employed multivariable regression to correct for possible confounders including methods of conception, multiple pregnancies, ethnicity, and socio-economic status. Our primary outcomes were maternal and perinatal mortality. Secondary outcomes included common maternal and perinatal complications, as well as cesarean section rate. RESULTS A cohort of 3 700 326 women gave birth during the study period. Of these women, 3.2% were above 40 years of age. Maternal mortality was rare in all groups, but significantly higher in multigravid women over 50 years old. Perinatal mortality was significantly higher in all pregnancies of women over 40 years old, but not for primigravida over 50 years old. The most notable results with the steepest increase were in maternal complications. Both primigravida and multigravida over 40 years old were at a two times higher risk of perinatal mortality, cesarean section, gestational diabetes, hypertensive disorders, and a low Apgar score after 5 minutes. The risk for women over 45 was almost tripled for perinatal mortality and gestational diabetes and six times higher for cesarean section. Women over 50 years old had a seven times higher risk of cesarean section, a four times higher risk of gestational diabetes, postpartum hemorrhage, and neonatal intensive care unit admission, and a 10 times higher risk of hypertensive disorders. CONCLUSIONS The risk of adverse maternal and perinatal outcomes for women over 40 years old surges as age increases. A novel aspect was the consistent increased risks not only for primigravid women but also for multigravida.

Abstract
OBJECTIVES This study investigated differences in the perinatal mortality rate between white-collar and blue-collar workers. METHODS Data from the “Report of Vital Statistics: Occupational and Industrial Aspects” in Japan covering the period from 1995 to 2015 were used. Five-year maternal age groups from 15-19 years to 45-49 years were analyzed according to work type, and the perinatal mortality rate for each age group and the age-standardized perinatal mortality rate according to maternal age were calculated in each analyzed year. A Bayesian age-period-cohort analysis was used to estimate age, period, and cohort effects for the perinatal mortality rate according to work type. Moreover, the perinatal mortality rate ratios between types of workers were estimated for each age group, period, and cohort. RESULTS The estimated perinatal mortality rate ratios of blue-collar to white-collar workers were above 1 in most of the age groups and cohorts. The age effect for the perinatal mortality rate among white-collar workers was the largest in the 15-year to 19-year age group, whereas that among blue-collar workers was the largest in the 45-year to 49-year age group. Furthermore, the estimated perinatal rate ratio between white-collar and blue-collar workers tended to increase with maternal age. The magnitude of the decrease of the cohort effects on the perinatal mortality rate was rather larger in blue-collar workers in the cohorts born between 1946-1950 and 1996-2000. CONCLUSIONS The magnitude of the disparity markedly increased with maternal age. Thus, middle-aged blue-collar workers need more prenatal care and preventive measures for perinatal mortality than white-collar workers.

Abstract
Background The perinatal mortality rate in Ethiopia is among the highest in Sub Saharan Africa. The aim of this study was to identify the spatial patterns and determinants of perinatal mortality in the country using a national representative 2016 Ethiopia Demographic and Health Survey (EDHS) data. Methods The analysis was completed utilizing data from 2016 Ethiopian Demographic and Health Survey. This data captured the information of 5 years preceding the survey period. A total of 7230 women who at delivered at seven or more months gestational age nested within 622 enumeration areas (EAs) were used. Statistical analysis was performed by using STATA version 14.1, by considering the hierarchical nature of the data. Multilevel logistic regression models were fitted to identify community and individual-level factors associated with perinatal mortality. ArcGIS version 10.1 was used for spatial analysis. Moran’s, I statistics fitted to identify global autocorrelation and local autocorrelation was identified using SatSCan version 9.6. Results The spatial distribution of perinatal mortality in Ethiopia revealed a clustering pattern. The global Moran’s I value was 0.047 with p-value <0.001. Perinatal mortality was positively associated with the maternal age, being from rural residence, history of terminating a pregnancy, and place of delivery, while negatively associated with partners’ educational level, higher wealth index, longer birth interval, female being head of household and the number of antenatal care (ANC) follow up. Conclusions In Ethiopia, the perinatal mortality is high and had spatial variations across the country. Strengthening partner’s education, family planning for longer birth interval, ANC, and delivery services are essential to reduce perinatal mortality and achieve sustainable development goals in Ethiopia. Disparities in perinatal mortality rates should be addressed alongside efforts to address inequities in maternal and neonatal healthcare services all over the country.

Influence of Family Income Level on Obstetric and Perinatal Outcomes in Spain. SUSTAINABILITY 2020. [DOI: 10.3390/su12145523] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 11/17/2022]
Abstract
For pregnant women, having a low family income status is associated with late prenatal attendance and an increased risk of adverse outcomes during pregnancy, delivery, and immediately after delivery. However, the influence of the socioeconomic level on maternal and child health may be minimal as long as the health system model is able to neutralise health inequity. For this reason, the objective of this study is to determine the relationship between the socioeconomic level assessed through monthly household income and obstetric and perinatal outcomes in the Spanish Health System, where midwives play a relevant role. To meet this objective, a cross-sectional observational study aimed at women who have been mothers between 2013 and 2018 in Spain was developed. The final study population was 5942 women. No statistically significant differences with linear trend were found between income level and obstetric and perinatal outcomes after the adjustment by confounding factors (pregnancy composite morbidity, p = 0.447; delivery composite morbidity, p = 0.590; perinatal composite morbidity, p = 0.082; postpartum composite morbidity, p = 0.407). The main conclusion is that, in the current Spanish health system, household income as an indicator of socioeconomic status is not related to perinatal outcomes after the adjustment by confounding factors. These results are likely due to the public model of our health system that serves all citizens on equal footing, although other social and individual factors may have influenced these results

BMC Pediatr 2020; 20:142. [PMID: 32238144 PMCID: PMC7110778 DOI: 10.1186/s12887-020-02031-x] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/14/2019] [Accepted: 03/12/2020] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Globally, about 2.7 million neonates die annually and more than 99% of these deaths happened in developing countries. Although most neonatal deaths are preventable and attempts had been taken to tackle these deaths, an aggregate of 30 neonatal deaths per 1000 live births had been reported in Ethiopia. In this regard, identifying the predictors could be an important step. However, evidence on the incidence and predictors of neonatal mortality has been limited in Ethiopia, in the study area in particular. Even the available studies were limited in scope and were retrospective or cross section in nature. Thus, this study is aimed at assessing the incidence and predictors of neonatal mortality among neonates admitted in Amhara regional state referral hospitals, Ethiopia.. METHOD A multi center prospective follow up study was conducted on 612 neonates admitted in Amhara region referral hospitals from July 01 to August 30, 2018. A simple random sampling technique was used to select three of all referral hospitals in the study settings and all neonates admitted in the selected hospitals were included. Data were entered into Epi info version 7.0 and exported to STATA 14.0 for analysis. Cox proportional hazard regression model was fitted to identify predictors of neonatal mortality. Crude and Adjusted hazard ratio with 95% confidence interval was computed and variables' statistical significance was declared based on its AHR with 95% CI and p-value ≤0.05. RESULT Overall, 144 (18.6%) neonates died with a total person-time of 4177.803 neonate-days which is equivalent to the neonatal mortality rate of 186 per 1000 admitted neonates with 95% CI (157,219). The incidence rate of neonatal mortality was 27 per 1000 admitted neonates with 95%CI (23, 33). Maternal age ≥ 35 years (AHR = 2.60; 95%CI: 1.44, 4.72), mothers unable to read and write (AHR = 1.40; 95%CI: 1.23, 2.44), multiple pregnancy (AHR = 3.96; 95%CI: 2.10, 7.43) and positive maternal HIV status (AHR = 6.57; 95%CI: 2.53, 17.06) were predictors of neonatal mortality. CONCLUSION In this study, the neonatal mortality rate was higher than the national figure. Its most predictors were found to be modifiable. Thus, the stakeholders would better consider the aforementioned predictors to decrease this higher burden.

Abstract
Recently, advanced maternal age (AMA) has been increasing due to late marriage and assisted reproductive technology. AMA is high-risk pregnancy associated with the life-threatening diseases such as hypertensive disorders of pregnancy (HDP). Recently we have reported novel AMA model mice using aged spontaneous pregnant mice, and found that the phenotypes of AMA model mice reflect the same characteristics as human AMA. We have also demonstrated that atypical angiogenic factors profiles including soluble VEGF-R1 (sFlt-1) and placental growth factor in both AMA pregnant women and AMA model mice. VEGF-endothelin-1 system have been also known as one of HDP-associated factors, however, there has been few reports on the relation between VEGF-endothelin-1 system and AMA. In this study, we investigated the profiles of VEGF-endothelin-1 system using our model mice's samples. As a result, VEGF and endothelin-1 levels were not significantly different between AMA and young individuals. Our results indicated that the mechanisms of hypertension in AMA may differ from those in young individuals from the point of VEGF-endothelin-1 system.

Abstract
UNLABELLED Aim This explorative study aimed to investigate the association of residential greenness, traffic noise, and air pollution with birth outcomes in several Alpine areas with unique topography. METHODS We used data from two cross-sectional studies (UIT, n = 573 and BBT, n = 518) in the Tyrol Region (Austria/Italy). Only mothers who had lived in their current residence during the whole pregnancy were included. They completed a questionnaire, and medical records were used to draw data on birth weight, low birth weight (LBW), preterm birth, and small for gestational age (SGA). Normalized Difference Vegetation Index (NDVI) in the year of birth was assigned at the residential address as a measure of greenness. Road/railway traffic noise (Ldn) and air pollution (NO2) were calculated about 10 years after birth and used as surrogates for exposure levels during pregnancy. RESULTS In the UIT survey, higher NDVI500-m was consistently associated with lower odds for LBW and SGA, while an increase of Ldn was associated with higher odds for LBW. Other effect estimates were in the expected direction albeit non-significant. In the BBT survey, most findings were inconclusive (for NDVI) or present only in subgroups (for Ldn and NO2). CONCLUSION This study provides inconclusive evidence that the surrounding environment might be associated with birth outcomes in mountainous areas. Given the disparate associations across the study areas, further research in larger representative samples is warranted.

Abstract
BACKGROUND Perinatal mortality remains a major international problem responsible for nearly six million stillbirths and neonatal deaths. OBJECTIVES To estimate the perinatal mortality rate in Sana'a, Yemen and to identify risk factors for perinatal deaths. METHODS A community-based prospective cohort study was carried out between 2015 and 2016. Nine-hundred and eighty pregnant women were identified and followed up to 7 days following birth. A multi-stage cluster sampling was used to select participants from community households', residing in the five districts of the Sana'a City, Yemen. RESULTS Total of 952 pregnant women were tracked up to 7 days after giving birth. The perinatal mortality rate, the stillbirth rate and the early neonatal mortality rate, were 89.3 per 1000, 46.2 per 1000 and 45.2 per 1000, respectively. In multivariable analysis older age (35+ years) of mothers at birth (Relative Risk=2.83), teenage mothers' age at first pregnancy (<18 years) (Relative Risk=1.57), primipara mothers (Relative Risk=1.90), multi-nuclear family (Relative Risk=1.74), mud house (Relative Risk=2.02), mothers who underwent female genital mutilation (Relative Risk=2.92) and mothers who chewed khat (Relative Risk=1.60) were factors associated with increased risk of perinatal death, whereas a positive mother's tetanus vaccination status (Relative Risk=0.49) were significant protective factors against perinatal deaths. CONCLUSION Rates of perinatal mortality were higher in Sana'a City compared to perinatal mortality at the national level estimated by World Health Organization. It is imperative there be sustainable interventions in order to improve the country's maternal and newborn health.

Abstract
BACKGROUND Infant mortality is an indicator of child health, and an explanatory variable to reflect the socioeconomic development of a country. We aimed to examine the changes and trends of infant mortality in the European Union (EU) and its 28 member states in the 1994-2015 period. METHODS We extracted data of deaths in children aged less than one year between 1994 and 2015 from the Eurostat database. We analysed secular variation in the EU overall, by country and by geographical region using joinpoint regression analysis. We conducted additional analyses to examine neonatal and early neonatal mortality trends. RESULTS Infant mortality in the EU has declined significantly from 8,3 to 3,6 per 1,000 live births (annual percent change=-3,8%; 95% confidence interval, -4,1 to -3,6). Among EU countries, we found the highest mortality rates throughout the study period in Romania and Bulgaria, and the lowest rates in Scandinavian countries (Finland, Sweden). There were significant decreasing trends in every country of the EU, which were most pronounced in former Soviet Baltic states and Eastern European countries, and least pronounced in Western European countries. Mortality rates have increased significantly in Greece in the last years, and plateaued in the United Kingdom and Ireland. CONCLUSIONS Our findings, which are based on official data, provide consistent evidence that infant mortality has declined steadily in the EU and its member states in the past decades, most markedly in Eastern European countries and former Soviet Baltic states. However, rates have risen or levelled off in some western countries in the past few years.

Abstract
Recently, advanced maternal age (AMA) has increased in Western countries because of late marriage and advances in assisted reproductive technology. One major complication of AMA is hypertensive disorders of pregnancy (HDP). While clinical investigations into human AMA have been reported, there has been limited information obtained from basic research. In this investigation, we established the AMA mouse model using aged pregnant ICR mice. We demonstrated that the phenotypes of aged pregnant ICR mice reflect the same characteristics as human AMA. The significant findings of our investigation are as follows: (1) The AMA mouse model manifested the same complication phenotypes of human AMA, including maternal obesity, declining fertility, small for gestational age, and a higher rate of intrauterine fetal death; (2) The AMA mouse model exhibited an increasing systolic blood pressure at late gestation (108.2 ± 7.7 vs. 92.7 ± 5.7 mmHg, P < 0.01) that normalized after delivery similar to human HDP patients; and (3) While HDP and placental dysfunction are complicated, AMA mice and human HDP AMA patients manifested a low serum soluble fms-like tyrosine kinase-1 (sFlt-1) level in late gestation (AMA group vs. control group, mice, 16800.0 ± 10709.5 vs. 26611.9 ± 8702.0 pg/mL, respectively, P < 0.01; human, 8507.6 ± 3298.7 vs. 14816.9 ± 5413.5 pg/mL, respectively, P < 0.05). In conclusion, the aged pregnant mouse model resembled human AMA. The AMA mouse model was complicated with HDP despite the low serum sFlt-1 level. Our findings provide evidence that the serum sFlt-1 level does not necessarily reflect the conventional pathogenesis of HDP in aged human and murine pregnancies and may contribute to the future management of HDP in AMA.

Abstract
Background Pregnancy at advanced maternal age has become more common in both developed and developing countries over the last decades. The association between adverse perinatal outcomes and advanced maternal age has been a matter of controversy in several studies. The objective of this study is to investigate the impact of advanced maternal age on perinatal and neonatal outcomes of nulliparous singleton pregnancies. Methods Records of patients admitted to the Department of Obstetrics and Gynecology, University of Cukurova School of Medicine, between January 2011 and July 2015 for routine mid-trimester fetal ultrasonography were retrospectively reviewed. The control (age: 18–34 years), advanced maternal age (35–39 years), and very advanced maternal age (> 40 years) groups included 471, 399, and 87 women, respectively. Results Gestational diabetes, gestational hypertension, and cesarean delivery rates were more common in the very advanced maternal age group, with compared with the advanced maternal age and the younger age group. There were no significant differences in regarding rates of spontaneous preterm delivery before 34 weeks of gestation, prolonged rupture of membranes, large for gestational age infants, and operative vaginal delivery rates between the groups. Also, there were no significant differences regarding in APGAR scores, the rate of low birth weight infants, and neonatal morbidity rates between the groups. However, admission to the neonatal intensive care unit requirement was more common in the two advanced maternal age groups compared with the control group. Conclusion Advanced maternal age is a risk factor for gestational diabetes mellitus, gestational hypertension, preeclampsia, small for gestational age infants, spontaneous late preterm delivery, and cesarean section, with significant potential clinical implications.

Abstract
OBJECTIVE To compare perinatal outcomes between spontaneous conception and assisted reproductive technologies (ART) among patients of advanced maternal age. METHODS 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. RESULTS 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. CONCLUSIONS 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.

Abstract
BACKGROUND One of the United Nations' Millennium Development Goals of 2000 was to reduce maternal mortality by 75% in 15 y; however, this challenge was not met by many industrialized countries. As average maternal age continues to rise in these countries, associated potentially life-threatening severe maternal morbidity has been understudied. Our primary objective was to examine the associations between maternal age and severe maternal morbidities. The secondary objective was to compare these associations with those for adverse fetal/infant outcomes. METHODS AND FINDINGS This was a population-based retrospective cohort study, including all singleton births to women residing in Washington State, US, 1 January 2003-31 December 2013 (n = 828,269). We compared age-specific rates of maternal mortality/severe morbidity (e.g., obstetric shock) and adverse fetal/infant outcomes (e.g., perinatal death). Logistic regression was used to adjust for parity, body mass index, assisted conception, and other potential confounders. We compared crude odds ratios (ORs) and adjusted ORs (AORs) and risk differences and their 95% CIs. Severe maternal morbidity was significantly higher among teenage mothers than among those 25-29 y (crude OR = 1.5, 95% CI 1.5-1.6) and increased exponentially with maternal age over 39 y, from OR = 1.2 (95% CI 1.2-1.3) among women aged 35-39 y to OR = 5.4 (95% CI 2.4-12.5) among women aged ≥50 y. The elevated risk of severe morbidity among teen mothers disappeared after adjustment for confounders, except for maternal sepsis (AOR = 1.2, 95% CI 1.1-1.4). Adjusted rates of severe morbidity remained increased among mothers ≥35 y, namely, the rates of amniotic fluid embolism (AOR = 8.0, 95% CI 2.7-23.7) and obstetric shock (AOR = 2.9, 95% CI 1.3-6.6) among mothers ≥40 y, and renal failure (AOR = 15.9, 95% CI 4.8-52.0), complications of obstetric interventions (AOR = 4.7, 95% CI 2.3-9.5), and intensive care unit (ICU) admission (AOR = 4.8, 95% CI 2.0-11.9) among those 45-49 y. The adjusted risk difference in severe maternal morbidity compared to mothers 25-29 y was 0.9% (95% CI 0.7%-1.2%) for mothers 40-44 y, 1.6% (95% CI 0.7%-2.8%) for mothers 45-49 y, and 6.4% for mothers ≥50 y (95% CI 1.7%-18.2%). Similar associations were observed for fetal and infant outcomes; neonatal mortality was elevated in teen mothers (AOR = 1.5, 95% CI 1.2-1.7), while mothers over 29 y had higher risk of stillbirth. The rate of severe maternal morbidity among women over 49 y was higher than the rate of mortality/serious morbidity of their offspring. Despite the large sample size, statistical power was insufficient to examine the association between maternal age and maternal death or very rare severe morbidities. CONCLUSIONS Maternal age-specific incidence of severe morbidity varied by outcome. Older women (≥40 y) had significantly elevated rates of some of the most severe, potentially life-threatening morbidities, including renal failure, shock, acute cardiac morbidity, serious complications of obstetric interventions, and ICU admission. These results should improve counselling to women who contemplate delaying childbirth until their forties and provide useful information to their health care providers. This information is also useful for preventive strategies to lower maternal mortality and severe maternal morbidity in developed countries.

Abstract
OBJECTIVES To describe the effect of extremely advanced maternal age (EAMA) on maternal/neonatal outcomes. METHODS This was a case-control study in which 127 women ≥40 years at the time of delivery out of 2853 singleton hospital deliveries in Ondokuz Mayis University between 1 January 2008 and 31 August 2010 constituted the study group. One hundred and twenty-seven else were chosen randomly out of 2412, 21-35 years old women, via a computer system as controls. Demographic features of 254 mothers and infants as well as maternal and neonatal complications were recorded. RESULTS Mean maternal age was 41.5 ± 1.9 (40-49) years in EAMA group and 28.9 ± 4.2 (21-35) years in controls. Primigravidity was 19.6% in the EAMA group, whereas 37.8% in controls (p = 0.003). No difference was found between groups according to route of delivery, stillbirth, preterm birth, congenital abnormalities, gender of babies, NICU admission and respiratory problems (for all p > 0.05). A 5th min Apgar score <7 was more frequent in babies born to EAMA mothers compared to controls (9.8% versus 4.9%, p = 0.004). CONCLUSION The present study shows that EAMA mothers and their offsprings have similar peri and neonatal risks compared to younger mothers, except lower 5th minute Apgar scores. We conclude that with good perinatal care, EAMA women and their babies can pass through the perinatal period with similar risks of younger women.

Abstract
OBJECTIVE The objective of this study was to investigate whether moderately increased maternal age is associated with obstetric and neonatal outcome in a contemporary population, and to consider the possible role of co-morbidities in explaining any increased risk. STUDY DESIGN Secondary analysis of routinely collected data from a large maternity unit in London, UK. Data were available on 51,225 singleton deliveries (≥22 weeks) occurring to women aged ≥20 between 2004 and 2012. Modified Poisson regression was used to estimate risk ratios for the association between maternal age and obstetric and neonatal outcome (delivery type, postpartum haemorrhage, stillbirth, low birthweight, preterm birth, small for gestational age, neonatal unit admission), using the reference group 20-24 years. Population attributable fractions were calculated to quantify the population impact. RESULTS We found an association between increasing maternal age and major postpartum haemorrhage (≥1000ml blood loss) (RR 1.36 95% CI 1.18-1.57 for age 25-29 rising to 2.41 95% CI 2.02-2.88 for age ≥40). Similar trends were observed for caesarean delivery, most notably for elective caesareans (RR 1.64 95% CI 1.36-1.96 for age 25-29 rising to 4.94 95% CI 4.09-5.96 for age ≥40). There was evidence that parity modified this association, with a higher prevalence of elective caesarean delivery in older nulliparous women. Women aged ≥35 were at increased risk of low birthweight and preterm birth. We found no evidence that the risk of stillbirth, small for gestational age, or neonatal unit admission differed by maternal age. CONCLUSIONS Our results suggest a gradual increase in the risk of caesarean delivery and postpartum haemorrhage from age 25, persisting after taking into account maternal BMI, hypertension and diabetes. The risk of low birthweight and preterm birth was elevated in women over 35. Further research is needed to understand the reasons behind the high prevalence of elective caesarean delivery in nulliparous older mothers.

Abstract
Duchenne muscular dystrophy (DMD) is an X-linked recessive neuromuscular disease caused by mutation in the DMD gene. A 38-year-old woman was referred to our hospital with her son who was diagnosed with DMD. Multiplex PCR failed to detect DMD mutations in the affected child. The female carrier underwent preimplantation genetic diagnosis by linkage analysis and gender determination. Eight embryos were biopsied after in vitro fertilization. Two healthy embryos determined both as females (E1 and E3) were transferred. Although the paternal allele was absent in E3, it was considered to be a result of allele dropout for the STR-49 marker. Surprisingly, a female and a male baby were delivered at 38 gestational weeks, suggesting that E3 was a male embryo with the allele dropout occurring at the SRY gene. Exon 2 duplication was detected in the DMD patient and the carrier mother using next-generation sequencing and multiple ligation-dependent probe amplification. Next, we verified the duplication of exon 2 by real-time PCR, using a special primer at 3' of intron 1, very close to exon 2. Finally, we confirmed that both newborns inherited the normal allele, using quantitative real-time PCR and linkage analysis.
