A vanishing twin (VT) occurs in up to 30% of early diagnosed twin pregnancies and is associated with an increased risk of fetal aneuploidy. Here, we describe our experience in a large VT population of 847 patients that underwent noninvasive prenatal testing (NIPT) for common fetal trisomies over a three-year period. All patients underwent an ultrasound examination prior to NIPT. Two comparison populations were included, namely, the singleton (n = 105,560) and the viable multiple gestation pregnancy samples (n = 9691) collected over the same period. All NIPT samples in the VT population received a result, of which 14 were high-risk for trisomy 21 (1.6%), nine for trisomy 18 (1.1%), and six for trisomy 13 (0.7%). Diagnostic testing confirmed the presence of trisomy 21 in 6/12 samples, giving a positive predictive value of 50%. One trisomy 18 case and no trisomy 13 cases were confirmed. The time between fetal demise and NIPT sampling did not appear to affect the number of true- or false-positive cases. In conclusion, NIPT is an effective screening method for trisomy 21 in the surviving fetus(es) in VT pregnancies. For trisomies 18 and 13, a positive NIPT should be interpreted carefully and ultrasound monitoring is preferrable over invasive diagnostic testing.

INTRODUCTION: In the most recent recommendations of the International Federation of Gynecology and Obstetrics (FIGO), a chapter was dedicated to the physiological approach and to the description of fetal mechanisms developed to respond to hypoxia. Our objective was to classify the type of hypoxia in the case of metabolic acidemia and to describe the order of appearance of fetal heart rate abnormalities in cases of gradually evolving hypoxia. MATERIAL AND METHODS: 132 neonates born between 2018 and 2020 with acidemia were included. We excluded preterm birth, fetuses with congenital anomaly and twin pregnancies. Intrapartum cardiotocography traces were assigned to one of these four types of labor hypoxia: acute, subacute, gradually evolving and chronic hypoxia. For gradually evolving hypoxia, fetal heart rate abnormalities were described according to the FIGO classification. RESULTS: 36 cardiotocography traces (27.3%) were classified as acute hypoxia, 14 (10.6%) as subacute hypoxia, and 3 (3.2%) as chronic hypoxia; gradually evolving hypoxia occurred in 62 cases (47%). In 77.4% of cases of gradually evolving hypoxia, deceleration was the first anomaly to appear, with loss of variability and bradycardia appearing later. Increased fetal heart rate was observed immediately after late deceleration in 46.8% of cases and was followed by a loss of variability or saltatory rhythm in 37.1% of cases. CONCLUSIONS: In cases of metabolic acidemia at term, the most frequent situation observed was gradually evolving hypoxia, with an initial occurrence of decelerations. The sequence of fetal heart rate modifications was variable.

INTRODUCTION: Female malignancies can require complex surgeries with expert techniques. A French certification of competence in gynecological cancer surgery has been elaborated in 2021 to certify specialized surgeons. For trainees, this would require a practical curriculum (number of rotations in certain departments), a surgical logbook and the theoretical European exam. The objective of our work was to interrogate trainees in gynecology and obstetrics on their oncological training and their opinion on the certification. MATERIAL AND METHODS: We conducted a national French prospective, observational study, using a web-based questionnaire from 06/2021-02/2022. All trainees were interrogated on their overall training in gynecological oncology. The opinion on the certification was assessed for the sub-group willing to specialize in oncological surgical gynecology. RESULTS: One hundred and twenty-five responded, and 66.1% wanted to specialize in surgical oncology. Many had completed one rotation in a specialized gynecological oncology center (45.3%) and in digestive surgery (48.8%). Concerning the theoretical training, 92% of the respondents believed it to be insufficient. Eighty participants (64%) wished to specialize in oncological surgical gynecology and were interrogated on the certification. The majority (65%) thought the three criteria were difficult to achieve but adequate. The most difficult criterium was the practical curriculum (70.5%) followed by the surgical logbook (55.1%) due to inequalities of training amongst French regions. CONCLUSION: Trainees in gynecology and obstetrics seem ready to take a specialized certification in surgical gynecological oncology to improve patient care. However, they expressed concerns due the disparities amongst regions in accessing certain specialized departments.
