The literature suggests an increased risk of chromosomal aberration, as well as pathogenic copy number variations (CNVs) on chromosomal microarray, for fetuses with NT between 3.0 and 3.4 mm. The aim of this study was to describe genetic findings of fetuses with NT between 3.0 and 3.4 mm in the first trimester. The secondary objective was to describe ultrasound findings and adverse outcomes for these fetuses.

In a pregnancy cohort (2015–2021) and a cohort of women of childbearing age (2021 and 2018), we defined three 90-day time periods: (1) first trimester, (2) preconceptional period (days 180–90 before pregnancy), and (3) January 01, 2021, and March 31, 2021 (women of childbearing age).

We quantified the exposure prevalence to each individual teratogen, and to valproate during pregnancy by calendar year to compare its use before and after the introduction of a pregnancy prevention program (2018).

The choice of planned mode of delivery in twin gestations and intrapartum clinical management are still debated with many discrepancies between countries and centers.&lt;/p&gt;&lt;p&gt;A lot of factors influence the physician's recommendation for mode of delivery in a twin gestation. In high income countries there seems to be consensus that vaginal delivery is a reasonable and likely the preferred option for delivery in near term uncomplicated twin pregnancies with the first twin in a vertex presentation.&lt;span&gt;&lt;sup&gt;1, 2&lt;/sup&gt;&lt;/span&gt; For many years it has been assumed that trial of labor (TOL) with the second twin being in a non-vertex presentation is associated with a higher maternal and neonatal risk, including an increased risk of combined delivery, and hence maternal and neonatal morbidity. However, more recent research has identified other independent risk factors such as higher gestational age, nulliparity, and the use of medical induction of labor. Several studies have now confirmed that TOL in twin pregnancies is a safe option, irrespective of second twin presentation if certain well-defined criteria are met, including a recent ultrasound regarding fetal position and estimated fetal weight focusing on weight con- or dis-cordance, and with the appropriate infrastructure and clinical expertise being accessible on labor ward. A sub-analysis of The Twin Birth Study, however, found that transverse/oblique lie of twin B after the birth of twin A was a risk factor for combined delivery and combined delivery a risk factor for adverse neonatal outcome.&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt; In this context it is important to remember that the majority of second twins present in a vertex position and that up to one tenth of second twins in non-vertex presentation experience a spontaneous version during labor affecting the likelihood of successful vaginal delivery.&lt;span&gt;&lt;sup&gt;3&lt;/sup&gt;&lt;/span&gt; Still, up to 4% of women opting for vaginal twin delivery ends up with “the worst of two worlds” going through a combined delivery with the burden of undergoing a vaginal delivery followed by an emergency cesarean section with its inborn risks.

In the latter period, the FBS frequency was lower (8.2% vs. 11.9% [&lt;i&gt;p&lt;/i&gt; &lt; 0.001]), and the proportion of acidemia at FBS was higher, both among sampled fetuses (12.5% vs. 7.1% [&lt;i&gt;p&lt;/i&gt; &lt; 0.001]), and in the total population (1.0% vs. 0.8% [&lt;i&gt;p&lt;/i&gt; = 0.022]). Immediate cesareans in general anesthesia due to fetal distress were more frequent among sampled fetuses (3.1% vs. 2.0% [&lt;i&gt;p&lt;/i&gt; = 0.006]) but not among nonsampled fetuses (0.4 vs. 0.4%). Incidence of Apgar scores &lt; 4 at 5 min was unchanged after FBS (&lt;i&gt;p&lt;/i&gt; = 0.66) but higher among nonsampled newborns (0.2 vs. 0.1 [&lt;i&gt;p&lt;/i&gt; = 0.033]). Apgar scores &lt;7 at 5 min were more frequent among both sampled and nonsampled groups.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Conclusions&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;After implementation of a revised CTG classification and a differently calibrated lactate meter in Sweden, the use of FBS was substantially lower.

Using serial intrapartum examinations of laboring women in Moshi, northern Tanzania, Bagandanshwa et al. demonstrate the association persistent fetal occipito-posterior (OP) position has with prolonged labor, and a higher incidence of operative (almost exclusively cesarean) deliveries.&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt; However, there are some interpretations and assumptions that should be scrutinized.&lt;/p&gt;&lt;p&gt;The introduction draws attention to the high incidence of persistent OP position in the population studied, compared to “white”/“European” parturients. The authors explain that the observed difference is by virtue of the single ethnicity of their study population being “black African women,” and that the anthropoid-shaped pelvis is more common in “Black African women.” The supporting radiological investigation cited is a study by Handa et al., studying magnetic resonance imaging (MRI) to compare pelvic dimensions in a sample of (self-reporting) African-American and white women. However, Handa states not to “use previously described categories to classify pelvic type in our research because those categories are founded on qualitative comparisons rather than quantitative measures.” Though differences observed between 40 racialized female cadavers in South Africa are cited, ignored is the study that finds one single anthropoid pelvis among 47 South African Zulu parturients.&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt; No other pelvic surveys from the African continent are mentioned. Despite literature that casts doubt upon its usefulness,&lt;span&gt;&lt;sup&gt;3&lt;/sup&gt;&lt;/span&gt; Bagandanshwa et al. assume that anthropoid proportions for the entire population of the “black” African continent are equal to the 40% found in the 121 “negro female” skeletons surveyed by Caldwell and Moloy. A questionable assumption, given the “one-drop rule” of racial categorization that operated in the USA prior to 1938, supported by genetic studies demonstrating up to 24% European ancestry among African Americans. Based on mtDNA haplotypes, African Americans share minimal ancestry with East Africans.&lt;span&gt;&lt;sup&gt;4&lt;/sup&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;The study by Bagandanshwa et al. involves “only one ethnicity.” I question whether this single sample is representative of the several thousand ethnicities within the African continent alone. The greatest genetic variation between groups on the planet is found in Africa.&lt;/p&gt;&lt;p&gt;Bagandanshwa et al. do not provide radiological evidence to support persistent OP position in labor due to the anthropoid pelvic shape alone. Little is offered to the reader regarding the labors conducted at Moshi. Other than the absence of regional analgesia, little is documented regarding the parturient's mobility, doula support, and one-to-one midwifery care, all of which have been shown to reduce complications associated with persistent OP position in labor.
