Abstract

ObjectiveCurrent data on the role of the umbilical cord in pregnancy complications are conflicting; estimates of the proportion of stillbirths due to cord problems range from 3.4 to 26.7%. A systematic review and meta-analysis were undertaken to determine which umbilical cord abnormalities are associated with stillbirth and related adverse pregnancy outcomes.MethodsMEDLINE, EMBASE, CINAHL and Google Scholar were searched from 1960 to present day. Reference lists of included studies and grey literature were also searched. Cohort, cross-sectional, or case-control studies of singleton pregnancies after 20 weeks' gestation that reported the frequency of umbilical cord characteristics or cord abnormalities and their relationship to stillbirth or other adverse outcomes were included. Quality of included studies was assessed using NIH quality assessment tools. Analyses were performed in STATA.ResultsThis review included 145 studies. Nuchal cords were present in 22% of births (95% CI 19, 25); multiple loops of cord were present in 4% (95% CI 3, 5) and true knots of the cord in 1% (95% CI 0, 1) of births. There was no evidence for an association between stillbirth and any nuchal cord (OR 1.11, 95% CI 0.62, 1.98). Comparing multiple loops of nuchal cord to single loops or no loop gave an OR of 2.36 (95% CI 0.99, 5.62). We were not able to look at the effect of tight or loose nuchal loops. The likelihood of stillbirth was significantly higher with a true cord knot (OR 4.65, 95% CI 2.09, 10.37).ConclusionsTrue umbilical cord knots are associated with increased risk of stillbirth; the incidence of stillbirth is higher with multiple nuchal loops compared to single nuchal cords. No studies reported the combined effects of multiple umbilical cord abnormalities. Our analyses suggest specific avenues for future research.

27. Assessment of Uterine Contraction and Atonic Bleeding during the Third Stage of Labor Using Shear Wave Elastography.

Abstract

Objective: This study aimed to clarify the relationship between fluctuations in uterine stiffness during the third stage of labor and blood loss upon placenta delivery using shear wave elastography. Methods: This prospective cohort study enrolled consecutive singleton pregnant women above 37 weeks of gestation who delivered infants transvaginally at a single perinatal center. Shear wave velocities (SWV) were continuously measured during the third stage of transvaginal labor using transabdominal ultrasound and these values were compared between groups with large (≥500 g) and small amounts of bleeding during this stage. Results: In total, 8 cases of large bleeding and 47 cases of small bleeding were compared. The large amount of bleeding group had a significantly lower median of minimum SWV values (0.97 [0.52–1.01] m/s than the small amount of bleeding group (1.25 [1.04–1.48] m/s p = 0.02). However, no significant differences were observed between the two groups in terms of median, mean, and maximum SWV values. The time from delivery of the infant to placental delivery was significantly longer in the large amount of bleeding group (median time: 370.5 s vs. 274 s, p < 0.05). Conclusion: Ultrasound quantification of uterine stiffness using shear wave elastography demonstrated that uterine contractions may influence the biological hemostasis of the uterus during the third stage of labor. Baseline uterine stiffness was weak and a longer duration of placental separation might be associated with cases of large amounts of bleeding during this stage. [ABSTRACT FROM AUTHOR]

Abstract

Aim: In Japan, unlike Western countries, tocolytic agents are administered in long‐term protocols to treat threatened preterm labor. Evaluating the side effects of this practice is crucial. We examined whether ritodrine hydrochloride had been administered in cases of maternal death, aiming to investigate any relationship between ritodrine administration and maternal death. Methods: This retrospective cohort study used reports of maternal deaths from multiple institutions in Japan between 2010 and 2020. Data on the reported cases were retrospectively analyzed, and data on the route of administration, administered dose, and clinical findings, including causes of maternal death, were extracted. The amount of tocolytic agents was compared between maternal deaths with ritodrine administration and those without. Results: A total of 390 maternal deaths were reported to the Maternal Death Exploratory Committee in Japan during the study period. Ritodrine hydrochloride was administered in 32 of these cases. The frequencies (n) and median doses (range) of oral or intravenous ritodrine hydrochloride were 34.4% (11) and 945 (5–2100) mg and 84.4% (27) and 4032 (50–18 680) mg, respectively. Frequencies of perinatal cardiomyopathy, cerebral hemorrhage, diabetic ketoacidosis, and pulmonary edema as causes of maternal death were significantly higher with ritodrine administration than without it. Conclusions: Our results suggest a relationship between long‐term administration of ritodrine hydrochloride and an increased risk of maternal death due to perinatal cardiomyopathy, cerebral hemorrhage, diabetic ketoacidosis, and pulmonary edema. In cases where ritodrine should be administered to prevent preterm labor, careful management and monitoring of maternal symptoms are required. [ABSTRACT FROM AUTHOR]

29. The plans for Tokyo Bay: the challenge of urban policy, 1950s–1990s.

Author

Hasegawa, Junichi

Abstract

At the conclusion of the 1950s in Japan, plans to reclaim and develop Tokyo Bay were proposed by the Japan Housing Corporation's president and a private think tank on economic affairs. The vision was incompatible with dispersion, the basic direction of the state's policy, so it was quickly rejected, but its legacy lived on as the trans-Tokyo Bay highway in 1997. This article argues that the lack of an effective national policy led to contradictory initiatives and divisions among the stakeholders, leaving open the way for the large-scale reclamation and development of Tokyo Bay.
