Objective

It has been suggested that induction of labour before 42 weeks of pregnancy prevents foetal complications. To evaluate the maternal and foetal outcomes of induced and spontaneous labour beyond gestational week 41 + 0.

Study design

We conducted a register-based nationwide cohort study that included pregnant women who were delivered in Sweden in 2016–2021. Women were classified into two groups: induction of labour (IOL) or spontaneous onset of labour (SOL). Maternal and foetal outcomes after IOL in gestational week 41 were compared with SOL in gestational week 41 and 42.

Results

Comparison between the IOL (n = 23,772) and SOL (n = 62,611) groups in gestational weeks 41 showed that various parameters were higher in the IOL group: caesarean deliveries (12.3 % and 4.6 %, P < 0.001), vacuum extraction (8.7 % and 6.9 %, P < 0.001), blood loss of > 1000 ml during labour (11 % vs 8.3 %, P < 0.001). The risks were remained significant even after adjusting for potential confounders (caesarean delivery: aOR 2.36; 95 % CI, 2.23–2.50, vacuum delivery: aOR 1.09; 95 % CI, 1.03–1.16, P = 0.002, and blood loss of >1000 ml: aOR 1.25; 95 % CI 1.18–1.31). The proportions of stillbirths (0.07 % and 0.18, P < 0.001), and newborns with apgar scores < 4 at five minutes (0.4 % vs 0.3 %, P < 0.001), were also higher in the IOL group. The risk of stillbirth after IOL in gestational week 41 was increased relative to SOL in the same week and remained high after adjusting for potential confounders (aOR 1.75; 95 % CI 1.07–2.80, P = 0.025).

The IOL group in gestational weeks 41 comprised a higher proportion of caesarean deliveries (12.3 % and 8.5 %, P < 0.001), but a lower (8.7 % and 9.7 %, P = 0.006) proportion of deliveries by vacuum extraction than the SOL group (n = 4548) in week 42.

Conclusions

Inducing labour at gestational week 41 in women with prolonged pregnancies may have adverse effects on foetal and maternal outcomes compared to those who experience spontaneous labour onset at the same gestational age. The risk of negative foetal outcomes after induction at week 41 appears similar to that in women who give birth after spontaneous labour at week 42.

Objectives

The Philippines has at least 25,000 stillbirth or intrauterine fetal demise (IUFD) cases every year. Despite its burden, there is scarce information on IUFD epidemiology in the Philippines. Hence, this study reported the epidemiology and placental pathology of IUFD in a tertiary hospital in the Philippines.

Study design

This cross-sectional study analyzed second- and third-trimester IUFD cases at the Philippine General Hospital from 2012 to 2021. We reviewed maternal sociodemographic and clinical characteristics and evaluated placental pathology. All statistical tests were done with GraphPad Prism software version 8.0.

Results

We recorded 947 (2.28 %) cases of IUFD out of 41,562 obstetric deliveries from 2012 to 2021. Out of 947 IUFD cases, 532 had placental pathology reports. Second-trimester IUFD cases showed higher rates of no antenatal care (42.86 %) compared to third-trimester cases (10.61 %). Hypertensive disorders were more common in third-trimester IUFD. Infarcts (23.34 %), calcifications (4.12 %), and hemorrhages/hematomas (3.00 %) were the most prevalent placental abnormalities. While these abnormalities were more common in third-trimester IUFD, placental and fetal membrane infections like chorioamnionitis were more frequent in second-trimester IUFD.

Conclusion

The results highlighted the differences in maternal sociodemographic and clinical characteristics, and placental pathology between second- and third-trimester cases of IUFD. These observations revealed distinct pathological processes and potential etiologies contributing to IUFD in the Philippines.

Background

Antiphospholipid Syndrome (APS) is a systemic autoimmune thrombophilic condition characterized by obstetric manifestations, including pregnancy loss, preeclampsia and fetal growth restriction. Early diagnosis and management are key to improve maternal and neonatal outcomes.

Objective

The aim of this study is to assess the perinatal outcomes in APS, the development of various adverse pregnancy outcomes (APO), and their association with specific antibody profiles.

Material methods

This observational study was carried out on booked cases of singleton pregnancy and diagnosed cases of primary APS in our High-Risk Pregnancy (HRP) clinic from January 2018 to December 2022 after approval from institutional ethics committee. Forty-three confirmed cases of primary APS were enrolled and started on low-dose aspirin and low-molecular-weight heparin (LMWH) as per the patient's body weight after confirmation of fetal heart activity radiologically until 36 weeks of gestation as a standard of care.

Results

Forty patients (93 %) had obstetric APS, and three patients (7 %) had thrombotic APS. During the course of the current pregnancy, adverse pregnancy outcomes (APO) developed in 12 (30 %) out of 40 cases of obstetric APS and in all 3 patients with thrombotic APS. Preeclampsia was seen in 11 (25.5 %), FGR in 12 (27.9 %), and preterm birth in 7 (16.2 %) cases. Patients with an antibody profile showing the presence of Anti-β2 GP-I positivity and ACL positivity had fewer APOs (20 % and 29 %) in comparison to patients with a LA and triple positive antibody profile (55 % and 50 %).

Conclusion

Treatment of pregnant women with APS causes significant improvement in the live birth rate. The late pregnancy complications like preeclampsia, FGR, and premature birth, occurring despite treatment still remains a challenge and emphasizes the need for stringent antepartum surveillance and timely delivery.

Although posthumous reproduction (PHR) is viewed unfavorably by some, it may be a desirable option for subjects whose partners died before they could complete their family planning. With particular regard to posthumous embryo implantation, questions arise regarding the definition of "conception" when a couple undergoes in vitro fertilization while both are alive, but the embryo is implanted in a woman's womb after one parent has died. In accordance with Italian Law 40/2004, access to medically assisted reproduction is contingent upon the survival of both partners in a couple. The legislative prohibition remains in effect unless the application of the reproductive technique has already resulted in the formation of embryos, and implantation is permitted to uphold "the rights of all the subjects involved, including the conceived", as stated in Article 1 of Law 40/2004. Since the enactment of the legislation, a number of Italian courts have issued rulings on PHR on a case-by-case basis. Recent government guidelines in Italy have sought to balance these considerations, giving due weight to the will of the woman, the potential unborn child, and the previous consent of the donor partner.

Cesarean section (C-section) delivery is associated with a higher risk of respiratory problems in newborns, particularly if performed electively at 37 weeks. This risk is greater than with spontaneous or induced labor but diminishes as gestation advances. To lower the incidence of respiratory issues in newborns, it is vital to promote natural labor, avoid unnecessary C-sections, and offer thorough prenatal care. Healthcare providers and expectant mothers should assess the risks and benefits of elective C-sections carefully. By advocating for natural labor and reducing unnecessary C-sections, the occurrence of respiratory problems in newborns can be decreased. Adequate prenatal care and monitoring are crucial for identifying and managing potential risk factors for respiratory diseases in newborns. It is crucial for healthcare professionals to educate expectant mothers about the risks of elective C-sections and the advantages of allowing labor to progress naturally. By fostering transparent communication and collaborative decision-making between healthcare providers and pregnant women, well-informed choices can be made that prioritize the health of both the mother and the baby. Furthermore, ongoing research and advancements in medical technology can improve our understanding of how delivery methods affect newborn respiratory health, ultimately leading to better outcomes and care practices in the future.

Childhood obesity represents a pressing global public health concern due to its widespread prevalence and its close connection to early-life exposure to risk factors. The onset of obesity is contingent upon the interplay of genetic composition, lifestyle choices, and environmental as well as nutritional elements encountered during both fetal development and early childhood. This paper critically examines research discoveries in this area and concisely outlines the influence of breastfeeding on genetic predispositions associated with childhood obesity. Studies have demonstrated that breastfeeding has the potential to reduce childhood obesity by impacting anthropometric indicators. Moreover, the duration of breastfeeding is directly correlated with the degree to which it alters the risk of childhood obesity. Current explorations into the link between genetic factors transmitted through breast milk and childhood obesity predominantly focus on genes like FTO, Leptin, RXRα, PPAR-γ, and others. Numerous research endeavors have suggested that an extended period of exclusive breastfeeding is tied to a diminished likelihood of childhood obesity, particularly if sustained during the initial six months. The duration of breastfeeding also correlates with gene methylation, which could serve as the epigenetic mechanism underpinning breastfeeding's preventative influence against obesity. In summary, the thorough evaluation presented in this review underscores the intricate nature of the association between breastfeeding, genetic factors, and childhood obesity, providing valuable insights for future research efforts and policy formulation.

Women of childbearing age frequently express a desire for pregnancy even after a diagnosis of breast cancer and after undergoing treatment. The average age of primiparous women is rising and gynecologists and oncologists are faced with inquiries about pursuing childbearing after the diagnosis of breast cancer. We present a case of a 39 year old women who came to our clinic in 39th week of gestation, gave vaginal birth to a vigorous neonatus and underwent into dyspnea just two hours after the delivery. She voluntarily disclosed her advanced stage of breast cancer diagnosis, as she feared it could lead to the termination of her pregnancy. After she was released from the hospital, she did not attend any follow-up appointments at our clinic, hence we have no knowledge whether she contacted her oncologist or the outcome of her primary disease.
