Emanuel Friedman published his original labor curve showing the expected progression of normal labor in 1955, and that for multiparous patients in 1956.2,3 He plotted the individual labor progression of 500 nulliparous laboring women from a single center to calculate the average progression of labor. In his cohort, 70% of whom were between 20 and 30 years old, many were Caucasian, and 55% of women were delivered via forceps. Dr. Friedman classically identified the second stage of labor starting at 4cm dilatation. Since the mid-20th century, many practice patterns have changed, and today’s population of women delivering in the United States is diverse and, on average, older and heavier than in 1955; therefore, use of the traditional labor curve has been questioned. The investigators in this study performed a secondary analysis of data from a multicenter cohort of 26,838 patients with singleton gestation, spontaneous labor, and normal outcomes. Using a sophisticated statistical approach Zhang et al. produced a modern labor curve.","PeriodicalId":114053,"journal":{"name":"50 Studies Every Obstetrician-Gynecologist Should Know","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117214692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a South Australian population cohort study of 308,974 spontaneous and assisted pregnancies between 1986 and 2002 in women over age 20, assisted conceptions were associated with an increased risk of birth defects, including cerebral palsy, compared to spontaneous conceptions in fertile women (adjusted odds ratio 1.28, 95% confidence interval 1.16–1.41). However, when examining in vitro fertilization and intracytoplasmic sperm injection (ICSI) pregnancies, only ICSI with fresh transfer remained associated with an increased risk of birth defects compared to spontaneous conceptions in fertile women in adjusted models. These findings suggest that while patients should be counseled regarding the potential increased risk of birth defects with ART procedures such as ICSI, more research is needed regarding the impact of infertility itself and specific ART interventions on neonatal outcomes.","PeriodicalId":114053,"journal":{"name":"50 Studies Every Obstetrician-Gynecologist Should Know","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125437939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the 15,841 women who had standard screening and cell-free DNA analysis with neonatal outcome data, there were 68 chromosomal abnormalities (1 in 236). Of these, 38 were Trisomy 21 (1 in 417). Cell-free DNA analysis had a higher area under the curve (AUC) for trisomy 21, compared to standard screening (0.999 vs. 0.958, p = 0.001). Cell-free DNA analysis also had greater sensitivity, specificity, and positive predictive value compared to standard screening for trisomy 21, 18, and 13.

This multicenter prospective cohort study of over 30,000 cesarean deliveries demonstrates that risks of cesarean delivery increase sequentially, even in the absence of placenta accreta. The most dramatic increase is noted in the high rates of accreta with placenta previa and multiple cesarean deliveries, greater than 40% with 3 of more cesarean deliveries. This review highlights the key findings, methodology, and impact of this landmark study. It discusses other studies that continue to verify these results as well as contextualize them in the management of placenta accreta with developing centers of excellence.
