Is advanced maternal age associated with placental vascular malperfusion? A prospective study from a single tertiary center.

PURPOSE: Pregnancy at advanced maternal age (AMA) has become more common. There has been concern regarding the adverse effect deferring pregnancy might have on pregnancy outcomes. We aimed to prospectively study the effect of AMA on placental pathology. METHODS: A prospective case-control study was performed in a single university center. Placental histopathology, maternal demographics, labor characteristics, and neonatal outcomes of pregnancies with AMA were collected and compared to matched controls. We defined AMA as maternal age > 35 years at delivery. In attempt to isolate the effect of maternal age, we excluded cases complicated by preterm birth, hypertensive disorders, diabetes mellitus, small for gestational age, and congenital/genetic anomalies. RESULTS: The study group included 110 AMA patients that were matched with controls. The groups did not differ in maternal demographics, but the AMA group had a higher rate of assisted reproductive technologies (ART) as compared to the control group (p < 0.001). Placentas in the AMA group were characterized by a higher rate of maternal vascular lesions (MVM) (39.1% vs. 24.5%, p = 0.003), but not fetal vascular malperfusion lesions (p = 0.576). In multivariable analysis maternal age was associated with placental MVM lesions independent of all other maternal demographics (aOR 1.18 95% CI 1.06-3.17). Neonatal outcomes did not significantly differ between the groups. CONCLUSIONS: After excluding all background morbidities-AMA was associated with a higher rate of placental MVM lesions vs. controls. These findings suggest an independent effect of AMA on placental function. Large prospective trials are needed to study the clinical importance of these findings.

Endometrial thickness of less than 7.5 mm is associated with obstetric complications in fresh IVF cycles: a retrospective cohort study.

RESEARCH QUESTION: Does endometrial thickness affect the occurrence of obstetric complications in fresh IVF cycles? DESIGN: We conducted a retrospective cohort study that included all singleton deliveries resulting from fresh embryo transfers in a single centre between 2008 and 2014. Obstetric complications, i.e. preeclampsia, placental abruption, placenta previa, small for gestational age and preterm delivery, in singleton live births were compared among patients with an endometrial thickness of less than 7.5 mm and 7.5 mm or over on day of HCG triggering. We adjusted for confounders, including maternal age, body mass index, smoking, peak oestradiol, parity, chronic hypertension, pre-gestational diabetes, gestational diabetes, vanishing twin, inherited or acquired thrombophilia, and past pregnancy complications. RESULTS: A total of 5546 fresh embryo transfer cycles were carried out during the study period, of which 864 singleton deliveries met inclusion criteria. After adjusting for potential confounders, an endometrial thickness of less than 7.5 mm was found to be associated with increased risk for adverse obstetric outcome (adjusted OR 1.53; 95% CI 1.03 to 2.42; P = 0.04) even after excluding patients with prior pregnancy complications (adjusted OR 2.2; 95% CI 1.05 to 4.59; P = 0.035). CONCLUSIONS: Our results demonstrated that a thin endometrial lining was associated with obstetric complications that might be related to poor placentation. These findings should be validated in large prospective cohort studies.

Smartphone-based counseling and support platform and the effect on postpartum lactation: a randomized controlled trial.

BACKGROUND: Human milk lactation provides health benefits for both the mother and infant. Patients commonly report stopping breastfeeding sooner than they planned. Interventions with proper accessible counseling and support to the mother can potentially increase lactation rates and duration. OBJECTIVE: This study aimed to investigate the impact of introducing a smartphone-based daily feedback and counseling platform between women after delivery and a multidisciplinary lactation support team on lactation rates and various maternal and neonatal outcomes. Counseling was provided via a specifically developed application from a multidisciplinary team (obstetricians, nurses, lactation counselors, and psychologist) in an attempt to assist and counsel to maintain lactation. STUDY DESIGN: This was a prospective, single-center, randomized controlled trial. Women planning to lactate were recruited at postpartum day 1 and were randomized to (1) routine lactation counseling and support (control group) or (2) additional daily detailed counseling and feedback on lactation from the team via the application (App group). The primary outcome was partial or full lactation at 3 months after delivery. The secondary outcomes included lactation at additional time points up to 6 months after delivery. The study was adequately powered to detect a 15% difference in the primary outcome. RESULTS: A total of 197 patients were recruited, 97 in the App group and 100 in the control group. The 2 groups did not differ in any background or delivery characteristics. The App group showed higher rates of lactation 6 weeks after delivery (96.9% vs 82.0%; P<.001) and 3 months after delivery (81.4% vs 69.0%; P=.049) than the control group. Patients in the App group reported excellent satisfaction from the use of the application and their overall postnatal care. CONCLUSION: Our study has provided further information on the growing efficacy of technology platforms in obstetrical care. The introduction of a smartphone-based daily feedback and counseling platform between postpartum patients and a multidisciplinary lactation support team increased the lactation rates after delivery with excellent patient satisfaction.
