ABSTRACT
Age-related ovarian hypofunction includes a decrease in follicle quantity and quality as well as alterations in the ovarian microenvironment，the mechanisms of which are mainly related to mitochondrial dysfunction，free radical and antioxidant systems，telomere and telomerase alterations，and apoptosis，and is one of the major factors contributing to infertility in advanced maternal age （AMA）. Despite the tremendous progress in assisted reproductive technology in recent decades，few breakthroughs have been made in alleviating age-related ovarian hypofunction and improving reproductive outcomes for AMA. In recent years，there has been an increasing number of studies on the multi-level and multi-targeted mechanisms of traditional Chinese medicine （TCM） to improve age-related ovarian hypofunction by modulating mitochondrial homeostasis，alleviating oxidative stress，and inhibiting apoptosis，while more high-quality randomized controlled trials have demonstrated the clinical efficacy of TCM in assisted reproductive technology. Given this，this article presented a systematic review of recent research and randomized controlled trials on the mechanism of Chinese medicine active ingredients，single Chinese medicine， and Chinese medicine compounds in delaying age-related ovarian hypofunction，to clarify the current status and shortcomings of the research. This paper provides medication management of TCM for effectively alleviating age-related ovarian hypofunction and improving reproductive outcomes for AMA.
ABSTRACT
Resumo As inovações científicas em torno do estudo de cromossomos humanos surgidas após a segunda metade do século XX consolidaram a inserção da genética na assistência em saúde, no que tange ao diagnóstico pré-natal. A associação entre idade materna e síndromes genéticas, proposta por pesquisadores da biomedicina, produziu determinações sobre risco, referidas a gestantes a partir de determinada idade. O artigo apresenta as concepções de risco em torno do que a biomedicina considera ser idade materna avançada de modo a configurar o que é classificado como gestação de risco. A análise documental em manuais médicos brasileiros e estrangeiros das especialidades obstetrícia e genética evidenciou diferentes concepções de risco em relação ao fator etário reprodutivo. A idade materna é um aspecto presente na obstetrícia enquanto fator de risco de doenças. Para a especialidade genética, a idade materna não é um fator central de risco reprodutivo. A pesquisa constatou que a classificação de uma idade materna ideal para gestar é relativa e suscetível a alterações, segundo o contexto sócio-histórico de cada sociedade.
Abstract Scientific innovations around the study of human chromosomes, which emerged after the mid 20th century, consolidated the incorporation of genetics in prenatal diagnosis. The link between maternal age and genetic syndromes, proposed by biomedical researchers, produced resolutions about risks to pregnant women of a certain age. The article presents biomedicine concepts for advanced maternal age classified as a risk pregnancy. The review of Brazilian and foreign medical manuals in obstetrics and genetics showed different conceptions of risk concerning the reproductive age factor. Maternal age is an aspect in obstetrics related to the risk of diseases. For genetic expertise, advanced maternal age is not a central factor of risk for reproduction. The research found that the classification of an ideal maternal age for pregnancy is relative and susceptible to changes according to the socio-historical context of each society.

Background@#For the past decade, advanced maternal age (AMA) became more common in developed and developing countries due to the postponement of pregnancy because of career goals, widespread use of family planning, and advances in assisted reproductive techniques. This increase bears an impact on maternal and perinatal outcomes. The link between AMA and adverse maternal, perinatal, and neonatal outcome showed contradicting results. This study was conducted to investigate the association between AMA and adverse outcomes among nulliparous, Filipino with singleton pregnancies who gave birth in a private tertiary hospital. @*Methodology@#Medical records of patients admitted for delivery between January 2015 and December 2019 were reviewed retrospectively. The control (20–34 years), AMA 35–39 years, very AMA 40–44 years, and extremely advanced maternal age (EAMA) 45 years and above groups included 206, 111, 18, and 2, respectively. @*Results@#Five-year total deliveries at a private tertiary hospital were 8495 with a prevalence of 38.9% (95% confidence interval CI: 33.6%–44.3%) for elderly Filipino primigravids. AMA is a risk factor for diabetes mellitus and small for gestational age newborn in all 3 advanced age groups. Pregnancy induced hypertension, having cesarean section, admission of newborn to neonatal intensive care unit, and administration of antibiotics were more common to AMA but same risk for EAMA. AMA predisposes to having oligohydramnios, placenta previa and preterm delivery but pregnancy at EAMA predisposes more complications in maternal and neonatal outcomes such as having polyhydramnios, abruptio placenta, postpartum hemorrhage, maternal and neonatal death, low Appearance Pulse Grimace Activity and Respiration score, and stillbirth. There is no noted association between AMA and large for gestational age newborn, having meconium staining and delivering by classical cesarean section. @*Conclusion@#AMA in Filipino gravida patients is markedly linked with adverse obstetrical, perinatal, and neonatal outcomes. This study confirms the current trend among women over 45 years that leads to more significant obstetric complications and neonatal morbidities.

Pregnancy OutcomeABSTRACT
Abstract Objective The present study aims to analyze adverse fetal or neonatal outcomes in women with gestational diabetes, including fetal death, preterm deliveries, birthweight, neonatal morbidity and mortality, as well as the synergic effect of concomitant pregnancy risk factors and poor obstetric outcomes, as advanced maternal age, maternal obesity and pre-eclampsia in their worsening. Methods The present cohort retrospective study included all pregnant women with gestational diabetes, with surveillance and childbirth at the Hospital da Senhora da Oliveira during the years of 2017 and 2018. The data were collected from the medical electronic records registered in health informatic programs Sclinico and Obscare, and statistical simple and multivariate analysis was done using IBM SPSS Statistics. Results The study participants included 301 pregnant women that contributed to 7.36% of the total institution childbirths of the same years, in a total of 300 live births. It was analyzed the influence of pre-eclampsia coexistence in neonatal morbidity (p = 0.004), in the occurrence of newborns of low and very low birthweight (p < 0.01) and in preterm deliveries (p < 0.01). The influence of maternal obesity (p = 0.270; p = 0.992; p = 0.684) and of advanced maternal age in these 3 outcomes was also analyzed (p = 0,806; p = 0.879; p = 0.985).Using a multivariate analysis, the only models with statistic significance to predict the three neonatal outcomes included only pre-eclampsia (p = 0.04; p < 0.01; p < 0.01). Conclusion Only coexistence of pre-eclampsia showed an association with adverse neonatal outcomes (neonatal morbidity, newborns of low and very low birthweight and preterm deliveries) and can be used as a predictor of them in women with gestational diabetes.
Resumo Objetivo O presente estudo tem como objetivo analisar desfechos fetais ou neonatais adversos em mulheres com diabetes gestacional, incluindo morte fetal, partos prematuros, peso ao nascimento, morbilidade neonatal e mortalidade, bem como o efeito sinérgico de fatores de risco e maus desfechos concomitantes da gravidez, como idade materna avançada, obesidade materna e pré-eclâmpsia no seu agravamento. Métodos O presente estudo retrospetivo de coorte incluiu todas as gestantes com diabetes gestacional, com vigilância e parto no Hospital da Senhora da Oliveira durante 2017 e 2018. Os dados foram obtidos dos registos clínicos eletrônicos dos programas informáticos de saúde Sclinico e Obscare, e a análise estatística simples e multivariada foi feita utilizando o IBM SPSS Statistics. Resultados Os participantes do estudo incluíram 301 gestantes que contribuíram para 7,36% do total de partos da instituição, num total de 300 nados vivos. Foi analisada a influência da coexistência de pré-eclâmpsia na morbilidade neonatal (p = 0,004), na ocorrência de recém-nascidos de baixo e muito baixo peso ao nascimento (p < 0,01) e em partos prematuros (p < 0,01). Também foi analisada a influência da obesidade materna (p = 0,270; p = 0,992; p = 0,684) e da idade materna avançada nesses 3 desfechos (p = 0,806; p = 0,879; p = 0.985).Usando uma análise multivariada, os únicos modelos com significância estatística para predizer os três desfechos neonatais incluíram apenas a pré-eclâmpsia (p = 0,04; p < 0,01; p < 0,01). Conclusão Apenas a coexistência de pré-eclâmpsia mostrou associação com desfechos neonatais adversos (morbilidade neonatal, recém-nascidos de baixo e muito baixo peso e partos prematuros) e pode ser utilizada como preditor destes em mulheres com diabetes gestacional.

Pregnancy at advanced maternal age (≥35 years) has become very common worldwide. Pre-eclampsia (PE) is a serious complication of hypertensive pregnancy that is associated with considerable morbidity and mortality to both the mother and foetus/newborn. This research aimed to inspect the prevalence of PE in a single hospital located in Jeddah, Saudi Arabia, and examine the influence of advanced maternal age (≥35 years) on the occurrence of PE in singleton deliveries. MethodsA retrospective study (January 2011 to December 2018) was carried out at King Abdulaziz University Hospital (KAUH), located in Jeddah, Saudi Arabia. Categorical variables were evaluated with χ² test. Odds ratio (OR) with 95% confidence intervals (95% CI) was used to estimate the comparative risk of developing PE (the outcome variable) according to the maternal age (the exposure variable) at the time of pregnancy. ResultsDuring the study period, 3942 singleton deliveries occurred at KAUH. The demographic characteristics (age and PE) of the study population are summarized in Table 1. Overall, there were 2426 deliveries with a maternal age <34 years (61.5%), whereas there were 1516 deliveries with a maternal age ≥35 years (38.5%). Only 167 deliveries had a diagnosis of PE, thus yielding an overall prevalence of 4.2% in this retrospective study. The percentages of PE cases in patients with maternal age <34 years and ≥35 years were 3.7% and 5.1%, respectively. Two-tailed Chi-square test of independence showed that there was a statistical significance between advanced maternal age and occurrence of PE (p=0.02). To examine the comparative risk of developing PE with relation to the maternal age, an OR analysis showed that patients with advanced maternal age (≥35 years) were 1.4 times more likely to develop PE during gestation when compared to patients with <34 years, and this comparative risk was substantial (OR: 1.4, 95% CI: 1.1-1.9, p=0.03). ConclusionsThe low prevalence of PE (3.9%) in our study was largely in agreement with the published regional and international figures. Advanced maternal age (≥35 years) is a statistically significant factor for developing PE during pregnancy.
ABSTRACT
Background: The objective of this study was to compare the adverse obstetric and perinatal outcome of pregnancies in women with advanced maternal age > 35 years with that of younger women in age group 20-34 years.Methods: A retrospective comparative study was carried out in department of obstetrics and gynecology at Adesh Medical College over the period of one year from June 2017 to June 2018. The obstetric and perinatal outcome of 100 women with advanced maternal age (study group) was compared with those of 100 younger women aged 20-34 years (control group).Results: Among antenatal complications, women of advanced maternal age had increased incidence of hypertensive disorder of pregnancy (26.6% versus 4.4%; p = 0.00009) and breech presentation (8.8% versus 1.1%; p = 0.04). The rate of caesarean delivery was significantly higher in advanced maternal age (28.8% versus 17.7%; p = 0.05). In perinatal outcome, older women had significantly higher incidence of perinatal death (7.7% versus 0%; p = 0.01).Conclusions: Thus, from this study, it can be concluded that advanced age women had higher incidence of hypertensive disorder of pregnancies and mal presentation, were more likely to deliver by caesarean section and had increased incidence of perinatal death.
ABSTRACT
Objective:To explore the risk of adverse pregnancy outcomes in the primiparas and the multiparas with advanced maternal age. Methods:Through a retrospective cohort study, 6 129 elderly women who gave birth to a single child from January 2014 to December 2016 in the International Peace Maternity and Child Health Hospital, Shanghai Jiao Tong University School of Medicine were collected to compare the differences in pregnancy outcomes between the primiparas and the multiparas (parity=2). Logistic regression analysis was used to evaluate the risk of adverse pregnancy outcomes in the two groups of pregnant women. Results:Compared with the multiparas, the primiparas with advanced maternal age had a higher risk of premature rupture of membranes (adjusted OR=1.35, 95% CI 1.18-1.54), preeclampsia/eclampsia (adjusted OR=1.99, 95% CI 1.45-2.73), gestational diabetes mellitus (adjusted OR=1.32, 95% CI 1.15-1.51), small-for-gestation age (adjusted OR=2.49, 95% CI 1.78-3.48), and cesarean section (adjusted OR=1.45, 95% CI 1.30-1.62). The birth weight of infants delivered by the primiparas was slightly lower than that of the multiparas. Conclusion:In the advanced maternal age women, primiparas have a higher risk of adverse perinatal outcomes than multiparas, such as premature rupture of membranes, preeclampsia/eclampsia, gestational diabetes mellitus, small-for-gestation age and cesarean section.
ABSTRACT
Resumen OBJETIVO: Describir los desenlaces maternos y perinatales en embarazadas de edad avanzada. MATERIALES Y MÉTODOS: Estudio de dos cohortes, prospectivo y retrospectivo efectuado con base en la información de expedientes clínicos de pacientes atendidas en el Complexo Hospitalario Universitario de Ourense entre 2017 y 2018. Se establecieron dos cohortes: la cohorte A con edad mayor o igual a 40 años y la cohorte B con edad menor de 40 años. Se realizaron pruebas paramétricas y no paramétricas para determinar la asociación potencial entre las variables de estudio (χ2, t de Student, U de Mann-Whitney). RESULTADOS: Las pacientes de la cohorte A (n = 207) tuvieron significación estadística: índice de masa corporal mayor al inicio del embarazo (p = 0.028), mayor cantidad de embarazos previos (p = 0.001), a expensas de mayor cantidad de abortos (p < 0.001), estados hipertensivos del embarazo (p = 0.03), prematurez (p = 0.009), retraso en el crecimiento intrauterino (p = 0.006), macrosomía fetal (p = 0.04), inducciones (p < 0.001), cesáreas programadas o intraparto y hemorragia posparto (p = 0.001). No se encontraron diferencias en la paridad, amenorrea al parto, diabetes pregestacional-gestacional, peso fetal medio, Apgar, pH de la arteria umbilical y cantidad de recién nacidos con requerimiento de ingreso a la unidad de Neonatología. CONCLUSIONES: La edad materna avanzada es un factor de riesgo importante de morbilidad materna y perinatal. La mayor tasa de complicaciones descritas refleja la importancia del control exhaustivo del embarazo y vigilancia periparto minuciosa.
Abstract OBJECTIVE: To describe the maternal and perinatal results in pregnant women with advanced age. MATERIALS AND METHODS: A cohort study was conducted with prospective follow-up and retrospective data collection of the Clinical History of the University Hospital Complex of Ourense between 2017 and 2018. Two cohorts were established, cohort A with age greater than and equal to 40 years and the cohort B with age under 40 years. Parametric and non-parametric tests were performed to determine the potential association between the study variables (Chi-Square, Student's T, Mann-Whitney U). RESULTS: The cohort A patients (n = 207) presented with statistical significance: body mass index higher at the beginning of pregnancy (p = 0.028), higher number of previous pregnancies (p = 0.001), but at the expense of a higher number of abortions (p <0.001), hypertensive states of pregnancy (p = 0.03), prematurity (p = 0.009), intrauterine growth retardation (p = 0.006), fetal macrosomia (p = 0.04), inductions (p < 0.001), of both scheduled and intrapartum caesarean sections and postpartum hemorrhage (p = 0.001). No differences were found in parity, amenorrhea at delivery, pregestational / gestational diabetes, mean fetal weight, Apgar score, umbilical artery pH and number of newborns who required admission to the Neonatal Unit. CONCLUSIONS: Advanced maternal age is an important risk factor for maternal and perinatal morbidity. The higher rate of complications described reflects the importance of thorough pregnancy control and careful peripartum surveillance.
ABSTRACT
RESUMEN Introducción: El diagnóstico prenatal de alteraciones cromosómicas en Cuba se inició en La Habana en 1984, mediante análisis del líquido amniótico obtenido por amniocentesis en el segundo trimestre del embarazo. En 1987 se introdujo el diagnóstico por análisis de vellosidades coriónicas en el primer trimestre, como parte de un subprograma dentro del Programa Nacional de Diagnóstico y Prevención de Enfermedades Genéticas dirigido por el Centro Nacional de Genética Médica. Objetivo: Demostrar que la edad materna avanzada sigue siendo la principal indicación de estudio citogenético en las gestantes de alto riesgo en la provincia de La Habana. Métodos: Se realizó un estudio descriptivo, retrospectivo y de corte longitudinal que abarcó 12 909 historias clínicas de gestantes a las que se realizaron amniocentesis, indicadas en la consulta del Centro Provincial de Genética Médica de la Habana, en el período comprendido entre enero 2007 y diciembre 2016. Se analizaron diferentes parámetros relacionados con la cantidad de casos por años según diferentes criterios y se calculó la sensibilidad, especificidad, valor predictivo positivo y valor predictivo negativo de la edad materna como predictor de la ocurrencia de anomalías cromosómicas. Resultados: El principal criterio de indicación del estudio invasivo lo constituyó la edad materna avanzada con 82 por ciento de los casos, mostrando una sensibilidad de 86 por ciento y una tasa de falsos positivos que alcanzó el 95,85 por ciento. Sería de utilidad actualizar el subprograma de diagnóstico prenatal mediante herramientas que permitan recalcular el riesgo a priori, a un riesgo individualizado y reclasificar la población de alto riesgo genético. Conclusiones: A partir del estudio realizado se puede concluir que la avanzada edad materna constituye el principal criterio de indicación para estudio citogenético por amniocentesis en las gestantes de alto riesgo de La Habana(AU)
ABSTRACT Introduction: The prenatal diagnosis of chromosomal abnormalities in Cuba began in Havana in 1984, by analyzing the amniotic fluid by amniocentesis in the second trimester of pregnancy. In 1987, diagnosis by chorionic villus analysis was introduced in the first trimester, as part of a subprogram within the National Program for the Diagnosis and Prevention of Genetic Diseases led by the National Center for Medical Genetics. Objective: To validate that advanced maternal age continues to be the main feature to propose a cytogenetic study in high-risk pregnant women in the province of Havana. Methods: A descriptive, retrospective, longitudinal-section study was conducted in 12,909 medical records of pregnant women who underwent amniocentesis, proposed in the consultation of Havana Provincial Center for Medical Genetics, from January 2007 to December 2016. Different parameters related to the number of cases per year were analyzed according to different criteria and sensitivity, specificity, positive predictive value and negative predictive value of maternal age were calculated as a predictor of the occurrence of chromosomal abnormalities. Results: The main criterion for indicating this invasive study was the advanced maternal age in 82 percent of cases, showing 86 percent of sensitivity and 95.85 percent false positive rate. It would be useful to update the prenatal diagnosis subprogram using tools that allow the risk to be recalculated a priori to an individualized risk and to reclassify the population in high genetic risk. Conclusions: From this study it can be concluded that advanced maternal age constitutes the main criterion for indicating amniocentesis cytogenetic study in high-risk pregnant women in Havana(AU)

RESUMEN Introducción: La pesquisa prenatal de anomalías cromosómicas, mediante el uso de marcadores epidemiológicos y ecográficos del primer trimestre permite identificar gestantes con riesgo incrementado de síndrome de Down. Objetivos: Analizar la edad materna, la translucencia nucal, el ductus venoso y el hueso nasal, durante el cribaje del primer trimestre, en las gestantes que se realizaron diagnóstico prenatal citogenético, con el fin de evaluar la efectividad del mismo en la detección temprana del síndrome Down y su utilidad para la reducción del número de pruebas invasivas. Métodos: Se realizó un estudio descriptivo retrospectivo de corte transversal y se analiza una muestra de 3439 gestantes a las que se realizó el estudio citogenético indicado en el Centro Provincial de Genética Médica de La Habana, en el período comprendido entre el 3 de enero de 2006 y el 30 de diciembre de 2008. Resultados: La edad materna avanzada mostró una sensibilidad de un 87 por ciento del test y una tasa de falsos positivos de 99 por ciento. La translucencia nucal se comportó con una sensibilidad de 10 por ciento. El hueso nasal no mostró asociación con los cariotipos positivos para síndrome de Down. Al no realizarse sistemáticamente la presencia del ductus venoso, no se pudo establecer una asociación estadística. La estimación de riesgo de síndrome de Down basada únicamente en la edad materna avanzada determina una alta tasa de falsos positivos. Por lo que este marcador, unido a la evaluación de los marcadores ecográficos del primer trimestre para recalcular el riesgo individual, puede aumentar la efectividad en el diagnóstico y disminuir el número de pruebas invasivas. Conclusiones: La estimación de riesgo de síndrome de Down basada únicamente en la edad materna avanzada determina una alta tasa de falsos positivos. Por lo que este marcador, unido a la evaluación de los marcadores ecográficos del primer trimestre para recalcular el riesgo individual, puede aumentar la efectividad en el diagnóstico y disminuir el número de pruebas invasivas(AU)
ABSTRACT Introduction: The prenatal investigation of chromosomal abnormalities through the use of epidemiological and echographic markers on the first trimester, allows to identify pregnant women with an increased risk of Down syndrome. Objectives: To analyze maternal age, nuchal translucency, venous ductus and nasal bone, during the first trimester screening, in pregnant women who underwent prenatal cytogenetic diagnosis, in order to evaluate effectiveness in early detection of Down syndrome and the value for reducing the number of invasive tests. Methods: A descriptive retrospective cross-sectional study was carried out and a sample of 3439 pregnant women was studied. The cytogenetic study ordered at Havana Provincial Center for Medical Genetics was carried out from January 3, 2006 to December 30, 2008. Results: Advanced maternal age showed 87 percent sensitivity and 99 percent of false positive rate. Nuchal translucency accounted 10 percent of sensitivity. The nasal bone showed no association with positive karyotypes for Down syndrome. A statistical association of the venous ductus presence could not be established since the search was not systematically. Conclusions: The estimation of Down syndrome risk based solely on advanced maternal age determines high false positive rate. Therefore, this marker, together with the evaluation of the first trimester ultrasound markers for recalculating the individual risk, can increase the diagnostic effectiveness and decrease the number of invasive tests(AU)

Background: Obstetric outcome in women with advanced maternal age (AMA) is not usually studied especially in India.Methods: This study was a case control study. The cases were pregnancy in 100 women at 40 years of age and beyond and there were two control arms of 100 each of ages 20-29 years and 30-39 years. The demography, maternal complications, delivery outcomes and neonatal outcomes were compared.Results: Women with AMA were mostly multiparous and had higher Body Mass Index (BMI). Hypertensive disease in pregnancy was more common in AMA but the difference was statistically significant. Women with AMA were more likely to have gestational diabetes (p ≤0.011), more likely to have anemia (p=0.038), more likely to have preterm birth (p=0.001), other medical complications compare to the control group (p=0.005). They were also more likely to have Lower Segment Caesarean Section (LSCS) (p ≤0.001) and have postpartum complications. The birth weight of the neonate was significantly decreased in the AMA group (p <0.001). The neonates were also more likely to be admitted to Neonatal Intensive Care Unit (NICU) (p ≤0.006).Conclusions: Adverse maternal and neonatal outcomes were seen despite individualized and optimal obstetric care. Thus, these women need preconceptional counselling.
ABSTRACT
Background: Advanced maternal age defined as age 35 years and older at estimated date of delivery has become increasingly common in last two to three decades. The International Federation of Gynaecology and Obstetrics in 1958 recommended that all women going through their first pregnancy over the age of 35 years should be considered high risk for pregnancy and included in this category 1.Methods: A one-year prospective observational study conducted in a tertiary care hospital after institutional ethical clearance. All 165 women above 35yrs who delivered during this period were taken as Cohort 1. Same number of women aged between 20 and 34 years were randomly selected as comparison group (Cohort 2). Both the groups were compared in terms of preexisting medical disorders, obstetrical morbidities, antenatal complications, intrapartum complications.Results: Older and younger women had similar antenatal booking, occupational and socioeconomic status. The main reason for pregnancy at advanced age group was late marriage. The risk of chronic hypertension, gestational diabetes mellitus, pre-existing medical disorders were higher in advanced maternal age.Conclusions: Increasing maternal age is associated with elevated risks for pregnancy complications. They are at high risk for gestational diabetes, cesarean section and to have low birth weight babies. Since these women are at higher risk of complications, they should be advised to adhere to frequent antenatal visits and close supervision.
ABSTRACT
This review highlights the challenges, priority areas of research and planning, strategies for regulation of services and the need to develop guidelines and laws for fertility treatments during mid-life. The success rate of all treatments is poor in advanced age women because of declining ovarian reserve and natural fertility. There is often a need of third-party involvement which has its own ethical, legal and medical issues. Welfare of children born to older women and early death of parents are important concerns. Most of the new techniques such as the pre-implantation genetic diagnosis, oocyte augmentation, use of stem cells or artificial gametes, ovarian tissue preservation and ovarian transplantation are directed to improve, preserve or replace the declining ovarian reserve. These techniques are costly and have limited availability, safety and efficacy data. Continued research and policies are required to keep pace with these techniques. The other important issues include the patients' personal autonomy and right of self-determination, welfare of offspring, public vs. private funding for research and development of new technologies vs. indiscriminate use of unproven technology. It is important that mid-life fertility is recognized as a distinct area of human reproduction requiring special considerations.
ABSTRACT
Objective To explore the risk factors for gestational diabetes mellitus (GDM ) in advanced maternal age (AMA) at the early stage of pregnancy .Methods A total of 1200 subjects with AMA were enrolled in this study as AMA group from Jun 2016 to Jul 2017 in Beijing Obstetrics and Gynecology Hospital of Capital Medical University .Each group was further divided according to OGTT results :GDM group and NGDM group .The risk factors of GDM were analyzed .Results The prevalence of GDM was 24.17%(290/1200) .The history of type 2 diabetes in first-degree relatives,pre-pregnancy BMI,TG,FPG,FIns,and HOMA-IR were significantly different in the two groups (P＜0.05) .Pearson correlation analysis showed that GDM was positively correlated with the history of type 2 diabetes in first-degree relatives,pre-pregnancy BMI,TG,FPG,FIns and HOMA-IR (r= 0.519,0.413,0.451, 0.625,0.531,0.214,P＜ 0.05) .Multivariate logistic regression analysis showed that history of type 2 diabetes in first-degree relatives,pre-pregnancy BMI,TG,FPG,FIns and HOMA-IR were independent risk factors for GDM (OR=1.635,1.133,2.153,2.418,1.390,1.901,P＜0.05) .Conclusion During early pregnancy in subjects with AMA,TG,FPG,FIns,history of type 2 diabetes in first-degree relatives,pre-pregnancy BMI were independent risk factors for GDM .
ABSTRACT
With the development of the social economy, people′s opinion of marriage and birth have changed, more and more women are pursuing a career and a higher level of education,combined with the development of medical technology especially the assisted reproductive technology, and the implementation of the "Two- Child Policy", so there is a phenomena of delayed childbearing in China, leading to an increasing number of advanced maternal age. Many studies have reported an association between advanced maternal age and a higher risk of adverse pregnancy and delivery outcomes, but some studies have shown contradictory findings. This paper aims to explore the targeted treatment and nursing measures on advanced maternal age, then reduce the occurrence of adverse outcomes and improve the level of perinatal health care of our country, through summarizing the adverse maternal and perinatal outcomes, the influencing factors of adverse outcomes on advanced maternal age.
ABSTRACT
This systematic review aimed to evaluate the efficacy and safety of assisted hatching (AH) performed in couples with advanced maternal age.We searched for randomized controlled trials (RCTs) in electronic databases,including MEDLINE,EMBASE and CENTRAL (from inception to January 2018);in addition,we hand-searched the reference lists of included studies and similar reviews.We included RCTs comparing AH versus no treatment (control).The meta-analysis was performed by RevMan 5.3 software.The search retrieved 943 records and 8 RCTs were included,comprising 870 cycles (n=440 for AH,and n=430 for control).There was no significant difference in the rates of live birth (RR 0.88,95％ CI 0.65 to 1.18,3 RCTs,n=427,I2=0％),clinical pregnancy (RR 1.00,95％ CI 0.83 to 1.19,8 RCTs,n=870,I2=22％),implantation (RR 1.07,95％ CI 0.83 to 1.39,4 RCTs,n=1359,I2=0％),miscarriage (RR 1.13,95％ CI 0.66 to 1.94,2 RCTs,n=116,I2=0％) and multiple pregnancy (RR 0.89,95％ CI 0.31 to 2.52,1 RCT,n=97,I2=not applicable) between the treatment group and control group.No reasonable conclusions could be drawn regarding reproductive outcomes after AH in patients with advanced maternal age due to the small sample pooled in meta-analyses.Studies of high methodological quality and with adequate power are necessary to further investigate the value of AH in assisted conception of those patients.

ABSTRACT
Objective@#The elderly primigravid has inherent pregnancy risks which may have deleterious effects on both maternal and fetal outcomes. The purpose of this study is to review the obstetric and neonatal outcomes of singleton gestations among Filipino elderly primigravids who delivered in a tertiary government hospital from January 1, 2012 to December 31, 2016.@*Methods@#This is a retrospective cohort study of including 80 primigravid women aged 35 years and older (study group) and 160 primigravid women aged 20 to 34 years old (control group). Data was collected through review of hospital records, and data processing and analysis were carried out using the software, Stata 13. @*Results@#A total of 24,751 deliveries were attended to for the five-year period covered, giving the elderly primigravids a prevalence of 6.91%, with a mean age of 38 ± 2.63 years (range 35-43). Significantly, more women in the elderly group delivered at less than 36 weeks age of gestation, delivered abdominally, and had a history of infertility and important co-morbid conditions. No significant difference in the neonatal outcomes were noted between the two groups. @*Conclusion@#It can be suggested that there was no noted difference in terms of the maternal and neonatal outcomes between elderly primigravids than otherwise. Nevertheless, inherent differences between the study groups may be clinically important in customizing the management of these women.

Pregnancy OutcomeABSTRACT
PURPOSE: To identify the potential risk factors for preterm birth (PTB) in women with advanced maternal age in the Korean population. METHODS: We selected the data of 531 pregnant women and singletons in the Korean Preterm Collaborate Network Study. Among the data, we analyzed variables related to demographic characteristics, lifestyle factors, and delivery information. Maternal age was divided into two groups: younger ( < 35 years) and advanced (≥35 years). Multiple logistic regression analysis was performed to identify the potential risk factors for PTB in advanced maternal age. RESULTS: In advanced maternal age, education level, occupation, passive smoking, iron intake, and parity showed significant differences between term birth and PTB. In particular, women who were exposed to passive smoking (odds ratio [OR]=2.83, confidence interval [CI]=1.14~7.04) and had folic acid intake during pregnancy (OR=2.67, CI=1.11~6.43) were at a significantly increased risk of PTB, after adjusting for all variables. CONCLUSION: This study indicates that smoking and lifestyle factors are the potential risk factors for PTB in advanced maternal age.

Introducción: el embarazo en edades extremas de la vida constituye un riesgo innegable. Objetivo: describir los resultados maternos y perinatales en gestantes con avanzada edad. Métodos: se realizó una investigación de desarrollo, observacional, descriptivo, de corte transversal, en pacientes ingresadas en el servicio de Obstetricia del Hospital General Docente Mártires del 9 de Abril, de Sagua La Grande, en la provincia Villa Clara, Cuba, desde el 1ro de octubre de 2011 hasta el 30 de septiembre de 2015. La muestra la constituyeron 372 gestantes de 35 o más años de edad con gestaciones mayores de 22 semanas, que tuvieron su parto en la institución. Resultados: predominó el grupo etario de 35 a 39 años (87,1 por ciento). Las secundíparas representaron 46,3 por ciento. La vaginitis, la obesidad y la anemia fueron las enfermedades asociadas representaron 78,5 por ciento, 45,7 por ciento y 22,8 por ciento, respectivamente. La enfermedad hipertensiva gestacional (19,1 por ciento) y el oligohidramnios (17,7 por ciento) fueron las patologías más frecuentemente encontradas. Casi la totalidad de las gestantes logró el parto a término (97,6 por ciento). El inicio espontaneo del trabajo de parto ocurrió en 63,2 por ciento. La indicación de cesárea resultó en 40,1 por ciento. 88,2 por ciento de los neonatos fue normopeso y 94,8 por ciento tuvo buen Apgar al nacer. La mortalidad fetal fue de 2,2 por ciento. La hiperbilirrubinemia (2,4 por ciento) y las malformaciones congénitas (2,2 por ciento) fueron las morbilidades neonatales mayormente encontradas. 79 por ciento tuvo un puerperio fisiológico. Conclusiones: la edad materna avanzada incrementó la cifra de partos distócicos e influyó negativamente en los indicadores de morbimortalidad perinatal. Existe una tendencia al incremento de partos en edades avanzadas en esta localidad(AU)
Introduction: pregnancy in the extreme ages of life is an undeniable risk. Objective: describe the maternal and perinatal outcomes in pregnant women with advanced age. Methods: an observational, descriptive, cross-sectional study was carried out in patients admitted to the Obstetrics Service of the General Teaching Hospital in Sagua la Grande, Villa Clara, Cuba from 1st October 2011 to September 30, 2015. The sample consisted of 372 pregnant women aged 35 years or older with gestations older than 22 weeks who had their deliveries in the institution. Results: the predominant age group was 35 to 39 years (87.1 percent). Women having their second delivery accounted for 46.3 percent. Vaginitis, obesity and anemia were associated diseases presented by 78.5 percent, 45.7 percent and 22.8 percent respectively. Gestational hypertensive disease (19.1 percent) and oligohydramnios (17.7 percent) were the most frequently pathologies. Almost all of the pregnant women achieved full term delivery (97.6 percent). The spontaneous onset of labor occurred in 63.2 percent. The cesarean indication was 40.1 percent. 88.2 percent of the infants were normal and 94.8 percent had good Apgar at birth. Fetal mortality was 2.2 percent. Hyperbilirubinemia (2.4 percent) and congenital malformations (2.2 percent) were the most common neonatal morbidity. 79 percent had a physiological puerperium. Conclusions: advanced maternal age increased the number of distal births and had a negative influence on the indicators of perinatal morbidity and mortality. There is a tendency to increase births in advanced ages in this locality(AU)
