The decision to postpone parenting has gained momentum in recent years, a shift driven by evolving social dynamics and improved access to fertility treatments. Despite their increasing prevalence, pregnancies at advanced maternal ages are associated with increased risks of adverse maternal and neonatal outcomes. This article addresses the association between advanced maternal age and hypertensive disorders of pregnancies (HDPs), which are more prevalent and a significant cause of maternal morbidity and mortality in this population. This review explores the biological mechanisms and age-related risk factors that underpin this increased susceptibility and offers practical management strategies that can be implemented prior to, as well as during, each stage of pregnancy to mitigate the incidence and severity of HDPs in this group. Lastly, this review acknowledges both the short-term and long-term postpartum implications of HDPs in women of advanced maternal age.

Objective: To investigate prematurity rate in women aged ≥45 carrying a singleton pregnancy. Other maternal and neonatal outcomes are also described. Design: Retrospective cohort study. Setting: Women delivering a singleton pregnancy at a single tertiary medical center. Population: The study included all women aged 45 years and over who delivered at 20 weeks gestation or beyond over a 9-year period from May 2000 to May 2009. Methods: Women aged 45 years and over were identified. The study group was compared to a control group of women <40 years with singleton pregnancies conceived by in vitro fertilization (IVF) who delivered during the same time period. Main Outcome Measure(s): Maternal complications during pregnancy and neonatal outcome. Results: During the study period 278 women ≥45 years delivered a singleton pregnancy. The control group included 304 women. The rate of delivery before 37 weeks as well as before 32 weeks were very high in our study group (18.7 vs. 10.9%, p = 0.009 and 5.4 vs. 2.0%, p = 0.04, respectively). In multivariate analysis, older maternal age was not independently related to prematurity. Chronic hypertension (HTN) was found to be a major risk factor associated with prematurity in advanced maternal age. Conclusions: Women ≥45-years-old with a singleton pregnancy carry a higher risk of maternal and perinatal complications. Preterm birth is a significant complication in this age group and is associated with preexisting chronic HTN.

Objective: To examine long-term behavioral and neurodevelopmental outcome of children born growth restricted and exposed to hypertension in utero at 9 years of age. Methods: Somatic growth and neurocognitive outcomes were evaluated at age 9–10 years of age in 42 children born with intra uterine growth restriction (IUGR) after pregnancies complicated by hypertensive disorder (17 with maternal preeclampsia and 25 after gestational hypertension). This study group was compared to a control group of 78 IUGR children born after normotensive pregnancy. Results: Only weight was found to be significantly lower in the hypertensive-IUGR group, versus the normotensive IUGR children. No significant differences were found in any of the neurocognitive parameters including IQ, school achievements, and neurodevelopmental score at age 9–10 years. Conclusion: IUGR is a well known risk factor for later cognitive difficulties but maternal hypertensive disorder does not seem to add significantly to this risk.

Objective. To investigate maternal and neonatal outcome of pregnant women infected with H1N1 influenza virus Methods. We prospectively followed all pregnant women hospitalized with positive H1N1 influenza virus nasal polymerase chain reaction tests between September 2009 and April 2010. Maternal and neonatal complications were recorded. Results. Twenty-four women positive for H1N1 were hospitalized. Only 2 women suffered from asthma, all others had no co-morbidities. Most women were in the third trimester (14 women, 58%). Common presenting symptoms were dyspnea (83%) and Fever (79%). Eleven women (46%) had pneumonia/Adult Respiratory Distress syndrome (ARDS) on chest X-rays. Six women were actively delivered due to maternal or fetal distress. Gestational age at delivery for these women was significantly lower (34 weeks vs. 39 weeks, p = 0.005). Of women delivered, five were admitted to intensive care units (ICU), three needed mechanical ventilation, and one tracheostomy. Patients admitted to ICU had significantly higher white blood cell (WBC) and C-reactive protein (CRP) levels (p < 0.01, p < 0.01, respectively). The main neonatal complication was prematurity where delivery was indicated. Conclusions. H1N1 flu pandemic has the potential of causing serious maternal morbidity during pregnancy. ARDS, elevated WBC and CRP levels correlate with more severe cases. Prematurity is associated with severity of maternal disease.

The objective of this study was to examine the rate of respiratory morbidity in neonates delivered by elective cesarean delivery (ECD) at term, with a definite confirmation of gestational age (GA) by 1st-trimester ultrasound. Consecutive women carrying a singleton pregnancy and undergoing ECD at term (>38 1/7 weeks), confirmed by 1st-trimester ultrasound, were included in the study group. Multiple gestations, cesarean section (CS) in labor, CS performed after rupture of membranes and induced deliveries were excluded. The control group included women with a singleton pregnancy at term (>38 1/7 weeks) who delivered spontaneously. This group of women was randomly selected during the study period. The study group included 277 women delivered by ECD. The control group consisted of 311 women. Five newborns in the study group and none in the control group were admitted to the neonatal intensive care unit (NICU) due to respiratory disorders (p < 0.02). Excluding diabetic women did not change the results. On multivariate analysis, no other factors were found to independently influence the risk of respiratory complications. In our study, the rate of respiratory morbidity was found to be significantly higher in neonates delivered by ECD compared to those delivered vaginally. The fact that GA was confirmed by 1st-trimester ultrasound makes iatrogenic prematurity an unlikely sole cause for this excess morbidity.
