Sine Berntsen, Anja Pinborg
Increase in success rates with frozen embryo transfer (FET) and reduced risk of ovarian hyperstimulation syndrome (OHSS) and multiple pregnancies has lead to a steady rise in FET. Further, FET is associated with lower risk of prematurity and low birth weight in singletons, when compared with fresh transfer. However, there is a growing concern of increased risk of large for gestational (LGA) and/or macrosomic children after FET. Macrosomic/LGA births have a higher risk of cesarean section, fetal hypoxia and stillbirth...

Cesarean sections have been associated in the literature with poorer newborn health, particularly with a higher incidence of respiratory morbidity. Most studies suffer, however, from potential omitted variable bias, as they are based on simple comparisons of mothers who give birth vaginally and those who give birth by cesarean section. We try to overcome this limitation and provide credible causal evidence by using variation in the probability of having a c-section that is arguably unrelated to maternal and fetal characteristics: variation by time of day...

OBJECTIVE: Although uterine didelphys per se is not associated with an impaired ability to conceive, the association between uterine anomalies and gestational trophoblastic neoplasia (GTN) remains unclear. The management of chemotherapy-resistant GTN in women with uterine didelphys raises a new issue regarding whether to perform a hemi-hysterectomy. CASE REPORT: A 23-year-old, gravida 1, para 0 Japanese woman was referred with a failed intermittent cervical dilatation for hematometra...

In the United States, women are routinely forced to undergo cesarean sections, episiotomies, and the use of forceps, despite their desire to attempt natural vaginal delivery. Yet, the current American legal system does little to provide redress for women coerced to undergo certain medical procedures during childbirth. Courts and physicians alike are prepared to override a woman's choice of childbirth procedure if they believe this choice poses risks to the fetus, and both give little value to the woman's right to bodily autonomy...

Previous studies have revealed significant differences in microbiome compositions between infants delivered via cesarean section (C-section) and natural vaginal birth. However, the importance of the delivery mode in the first days of life remains unclear. Importantly, this stage is minimally affected by infant feeding. Here, we used a metagenomic sequencing technique to characterize the meconium microbiome from the feces of a Chinese cohort of vaginally and C-section-delivered infants, including in vitro fertilization (IVF) newborns, during the first 24 h after birth...

BACKGROUND: Escalation in the global rates of labour interventions, particularly cesarean section and oxytocin augmentation, has renewed interest in a better understanding of natural labour progression. Methodological advancements in statistical and computational techniques addressing the limitations of pioneer studies have led to novel findings and triggered a re-evaluation of current labour practices. As part of the World Health Organization's Better Outcomes in Labour Difficulty (BOLD) project, which aimed to develop a new labour monitoring-to-action tool, we examined the patterns of labour progression as depicted by cervical dilatation over time in a cohort of women in Nigeria and Uganda who gave birth vaginally following a spontaneous labour onset...

When physicians performed cesarean sections in the nineteenth century, they customarily sought agreement from all present before proceeding. In contrast, after the introduction of electronic fetal monitoring in the late 1960s, obstetricians obtained permission for a cesarean by offering a choice that ensured consent-give birth by cesarean or give birth vaginally to a damaged or dead baby. This article argues that the manner in which physicians obtained consent for cesareans in the nineteenth century was one factor that kept the cesarean rate low, while the manner in which physicians obtained consent in the late twentieth and early twenty-first centuries was one factor driving up the cesarean rate...

Progesterone is an essential hormone that induces deep immune adaptations favoring pregnancy maintenance. We aimed at evaluating the effects of progesterone on the synthesis of pro- and anti-inflammatory cytokines by mononuclear cells isolated from human placental blood stimulated with lipopolysaccharide, emulating an infection-inflammation environment. Mononuclear cells isolated form human placental blood were obtained from nine women undergoing elective cesarean delivery at term (not in labor), isolated by density gradient sedimentation, cultured and co-stimulated with lipopolysaccharide (500 ng/ml) from Escherichia coli in the presence or not of progesterone (0...

Cesarean (C-section) delivery, recently shown to cause excess weight gain in mice, perturbs human neonatal gut microbiota development due to the lack of natural mother-to-newborn transfer of microbes. Neonates excrete first the in-utero intestinal content (referred to as meconium) hours after birth, followed by intestinal contents reflective of extra-uterine exposure (referred to as transition stool) 2 to 3 days after birth. It is not clear when the effect of C-section on the neonatal gut microbiota emerges...

REVIEW

One out of seven of all parturients and one out of five primigravid women deliver by caesarean section. Of four women having undergone caesarean section, three will give birth vaginally, provided that the indication for surgery has been temporary by nature. Spontaneous beginning of labor and a previous vaginal delivery improve the chances of succesful of vaginal delivery. Rupture of the uterus in subsequent pregnancies is the most feared sequel to a caesarean section, with an occurrence of 0.2 to 1.5%. Delivery by caesarean is indicated in case of previous rupture of the uterus, hysterotomy through vertical incision, and more than two previous caesarean sections...

Female sterilization procedures include postpartum partial salpingectomy via cesarean or minilaparotomy incision, interval laparoscopic procedures, or hysteroscopic placement of microinserts. Rates of failure and serious complications are low and comparable among the various methods. A hysteroscopic procedure requires a 3-month confirmatory hysterosalpingogram before it is considered effective for contraception. Hysteroscopic sterilization has been shown to be associated with a higher reoperation rate than laparoscopic procedures...

RATIONALE: Primary myelofibrosis is encountered with the myeloproliferative diseases and is the least prevalent among women of childbearing age. The prognosis is guided by pancytopenia, leukemic transformation and thrombosis which are the dominant complications. PATIENT CONCERNS: Data regarding protocol management during pregnancy in the context of myelofibrosis are insufficient. Fewer than ten cases have been described until now and half of this cases have resulted in fetal death due to placental infarction during the second and third trimesters...

BACKGROUND/AIMS: "Gentle" or "natural" cesarean sections are implemented to improve parental satisfaction. The objective of this study was to investigate whether there is a need for adopting such a gentle approach. METHODS: We recruited those with low-risk pregnancies scheduled for elective cesarean delivery at term. Three questionnaires were administered to both partners: prior to delivery, 2-5 days after delivery, and 6 weeks postpartum. Questionnaires assessed the couple's expectations, fears, and satisfaction prior to and after cesarean section...

Task sharing, the involvement of non-specialists (non-physician clinicians or non-specialist physicians) in performing tasks originally reserved for surgeons and anesthesiologists, can be a potent strategy in bridging the vast human resource gap in surgery and anesthesia and bringing needed surgical care to the district level especially in low-resource countries. Although a common practice, the idea of assigning advanced tasks to less-specialized workers remains a subject of controversy. In order to optimize its benefits, it is helpful to understand the current task sharing landscape, its challenges, and its promise...
