Cervical cerclage for prevention of preterm birth: the results from A 20-year cohort.

Cerclages can be used to prevent preterm birth, although their effectiveness and safety is disputed. We aimed to describe obstetric outcomes after cerclage procedures. We included 156 singleton pregnancies and six multiple pregnancies. In singleton pregnancies with history-indicated, short cervix-indicated and emergency cerclages, respectively 84.6, 76.5 and 43.8% resulted in late preterm or term deliveries. In singletons, the following complications were reported: excessive bleeding in one emergency cerclage procedure and three re-cerclage procedures in the history-indicated cerclage group. No perioperative rupture of membranes occurred in singletons. When comparing results of experienced and less-experienced gynaecologists, a remarkably smaller take home child rate was observed for singletons treated by less-experienced gynaecologists: 90.7% and 94.4% for the two experienced gynaecologist as compared to 85.0% for the group of less-experienced gynaecologists. In conclusion, cerclages in singletons result in few cerclage-associated complications and a high take home child rate, when performed by experienced gynaecologists. Impact statementWhat is already known on this subject? Prematurity is the leading cause of perinatal and neonatal mortality and morbidity worldwide. Cervical cerclages can be used to prevent preterm birth, although their effectiveness and safety is disputed.What the results of this study add? In our cohort study, singleton pregnancies with cerclages seem to have satisfactory obstetric outcomes. We found a very low prevalence of cerclage-associated complications in singleton pregnancies, for both history-indicated, short cervix-indicated and emergency cerclages. Additionally, take home child rates in singleton pregnancies were remarkably higher when cerclage procedures were performed by experienced gynaecologists, compared to less experienced gynaecologists.What the implications are of these findings for clinical practice and/or further research? Based on the observed difference in take home child rates, we advise all cerclage procedures to be performed by experienced gynaecologists only. This may mean that women with an indication for cerclage will be referred to a more experienced colleague, either in the same, or in another hospital. To ensure treatment by an experienced gynaecologist, simulation-based training could also provide a solution.

Absence of menstruation in female athletes: why they do not seek help.

BACKGROUND: It is known that amenorrhea is highly prevalent among female athletes. However, a large percentage of them do not seek help if this complaint occurs. We performed this study to gain more insight into the reasons why female athletes do not seek help when experiencing amenorrhea and how care for these women could be improved. METHOD: Qualitative focus group research. Female athletes were approached to take part in a focus group. They were asked about the main reasons for not reporting amenorrhea and how care for amenorrhea, in their opinion, would ideally be organised. The women were asked to make a list of their top five reasons for both subjects and discuss this among their peers. RESULTS: According to the participants, the five main reasons for not reporting the amenorrhea were: (1) normalizing of the subject, (2) the absence of menstruation is not perceived as a problem by the athletes themselves, (3) experienced shame and taboo, (4) prioritisation of sports performance, and (5) denial. Factors to improve care around menstrual cycle problems in female athletes were: (1) informing athletes, coaches, trainers and mentors, (2) informing doctors, (3) conducting more research on long-term consequences, (4) breaking the taboo on menstrual problems, and (5) having a multidisciplinary collaboration between different specialisms. CONCLUSION: By informing athletes, coaches, trainers, and mentors about menstrual cycle problems in athletes, more awareness among those groups can be created. According to the athletes, more research is needed on the long-term consequences of amenorrhea in sports, to enable them to make a better assessment of their possible future health risks. Women experience a taboo on discussing menstrual problems; role models discussing the problem may help in decreasing the taboo. A multidisciplinary collaboration of health care providers may improve care around female athletes with menstrual problems.

[Relative Energy Deficiency in Sports]. / Relatieve energiedeficiëntie bij sporters.

Relative Energy Deficiency in Sports, RED-S, caused by reduced energy availability can lead to a variety of symptoms. Both male and female athletes on all performance levels and ages are at risk of developing RED-S.Case 1 describes a patient with a low energy availability due to a disturbed energy balance with increased training intensity. She presented herself with an amenorrhea, one of the possible symptoms in women. Case 2 describes a patient with fatigue due to low energy availability, caused by an underlying eating disorder. Distincting RED-S from an eating disorder is difficult due to overlapping symptoms, but important given the difference in treatment. Altogether, RED-S can disrupt various body functions, therefore early recognition is desirable. Early recognition may prevent short- and long-term effects and reduce recovery time. Increasing awareness and knowledge on this topic is of great importance.

Simulation-based training of vaginal twin delivery for experienced gynaecologists: Useful or not?

OBJECTIVE: It is important to train clinicians to maintain and optimise maternal and neonatal outcomes after vaginal twin delivery. Simulation-based training provides opportunities for training in a realistic way without harming patients. The aim of this study is to evaluate the effect of simulation-based training concerning twin vaginal delivery on knowledge and comfort of obstetrician-gynaecologists. STUDY DESIGN: Obstetrician-gynaecologists participated in a twin vaginal delivery simulation between March 2018 and May 2019. Simulation-based training consisted of standardized patient interviews, didactic sessions and three different simulation-based scenarios: internal podalic version and breech extraction, assisted vaginal delivery and vaginal breech delivery with problems of aftercoming head. Pre- and posttraining, participants were asked to fill out questionnaires exploring knowledge concerning vertex-vertex twin deliveries and vertex-nonvertex twin deliveries, level of comfort performing various obstetric manoeuvres and counselling on mode of delivery for women pregnant with twins. Our primary outcome of interest was a change in knowledge or comfort surrounding vaginal twin delivery after completion of the simulation-based training. RESULTS: The estimated median number of vaginal twin deliveries performed by the participating thirty-four obstetrician-gynaecologists was 50 (IQR 20-100). Significant improvements were seen in knowledge regarding twin deliveries with vertex-nonvertex presentation (p < 0.01). In two of three questions regarding twin delivery with vertex-vertex presentation significant improvements were seen as well (p < 0.01). Before training, 40.6% of participants felt comfortable to perform internal podalic version compared to 91.2% afterwards (p < 0.01). Comfort with breech extraction increased from 69.7% to 97.1% pre- and posttraining, respectively (p < 0.01). Before training only 55.9% would strongly counsel patients towards vaginal twin delivery as opposed to 73.5% after training (p = 0.07). CONCLUSIONS: Simulation-based training results in beneficial effects on knowledge and comfort concerning vaginal twin deliveries for obstetrician-gynaecologists. This training suggested a potential impact on provider practice with a more favourable attitude towards twin vaginal birth.

[Breech delivery 'on all fours']. / Stuitbevalling in 'all fours'-positie.

Since the publication of the results of the Term Breech Trial (TBT) in 2000 the number of planned Caesarean sections for breech presentation has increased dramatically, at the expense of vaginal breech deliveries. The favourable effect of a planned Caesarean section for breech presentation on perinatal outcomes described in the TBT could not, however, be reproduced in later trials. A planned Caesarean section does carry an increased risk of maternal complications; furthermore, a previous Caesarean section leads to higher risks for both mother and child in any subsequent pregnancy. A recent prospective study advocates vaginal breech delivery 'on all fours', a position in which the mother leans on her hands and knees during delivery. A vaginal breech delivery in this position seems to be just as safe for the child as a planned Caesarean section, while a vaginal delivery is safer for the mother than a Caesarean section. This article describes two uncomplicated vaginal breech deliveries in the all fours position.

Comparison of planned caesarean delivery and planned vaginal delivery in women with a twin pregnancy: A nation wide cohort study.

OBJECTIVE: To compare, in women with twin pregnancy with the first twin in cephalic position, neonatal morbidity and mortality rates after planned caesarean delivery (CD) versus planned vaginal delivery (VD). STUDY DESIGN: A nationwide cohort study on women pregnant with twins and the first child in cephalic position, who delivered between 32 + 0-41 + 0 weeks between 2000 and 2012 in the Netherlands, using multivariate logistic regression analysis to compare neonatal morbidity and mortality according to planned delivery mode, and looking at subgroups 32 + 0-36 + 6 and 37 + 0-41 + 0 weeks. RESULTS: We included 21,107 women, of whom 1384 (6.6%) had a planned CD. Of the 19,723 women (93.4%) who had a planned VD, 19.7% delivered by intrapartum CD. We found no significant differences in 'any mortality' (aOR planned CD vs. planned VD 1.34 (95% CI 0.63-2.60)), the outcome 'Apgar score (AS) < 4 or death within 28 days' (aOR 1.28 (95% CI 0.77-2.11) or asphyxia-related morbidity (aOR 0.57 (95% CI 0.32-1.03)). After planned CD more prematurity-related morbidity (aOR 1.55 (95% CI 1.21-1.98)), other morbidity (aOR 1.50 (95% CI 1.26-1.78)) and 'any morbidity or mortality' (aOR 1.41 (95% CI 1.20-1.66) was noted. Trauma-associated morbidity was absent after planned CD and occurred 45 times (0.2%) after planned VD. Before 36 + 6 weeks, planned CD resulted in more perinatal mortality (aOR 2.10 (95% CI 0.92-4.76)), while asphyxia-related morbidity did not differ (aOR 0.80 (95% CI 0.41-1.54). Planned CD resulted in more 'any morbidity or mortality' (aOR 1.52 (95% CI 1.25-1.84)), 'AS < 4 or death within 28 days' (aOR 1.77 (95% CI 1.02-3.09)), prematurity-related morbidity (aOR 1.73 (95% CI 1.34-2.23)), and 'other morbidity' (aOR 1.56 (95% CI 1.28-1.90)). After 37 weeks, no significance differences in mortality, 'any morbidity or mortality <28 days' (aOR 0.96 (95% CI 1 (0.67-1.38)), or 'AS < 4 or death within 28 days' (aOR 0.41 (95% CI (0.10-1.70)) were found. There was less asphyxia-related morbidity after planned CD (aOR 0.24 (95% CI 0.06-1.002)). CONCLUSION: Planned VD results in comparable neonatal outcomes as planned CD for twin pregnancy with the first twin in cephalic position, even with a low intrapartum CD rate of 19.7%. At term, a planned CD may result in less asphyxia- and trauma-related outcomes.

Neurodevelopmental outcome of twins at two years of age according to the planned mode of delivery.

OBJECTIVES: To determine neurodevelopment at two years in twins. METHODS: At two years of age, all twins ≥32 weeks, delivered in our center and not randomized in the Twin Birth Study, underwent a neurodevelopment screen using the Ages and Stages Questionnaire (ASQ). Children with ≥1 abnormal ASQ domain score were evaluated by a pediatrician. Results were documented according to a planned cesarean section (PCS) or a planned vaginal delivery (PVD). RESULTS: An ASQ was obtained from 185 children (67%). No significant differences in percentages of abnormal scores were found between the PCS group and the PVD group or between twins A and B. Pediatric assessment revealed three children with a neurodevelopmental delay. Five other children were already under pediatric or general practitioner care for other reasons. One child with a congenital anomaly was born by a PCS, two twins A and five twins B were born in the PVD group. CONCLUSION: ASQ screening revealed no significant differences in abnormal neurodevelopment in twins at two years of age according to the mode of delivery. Pediatric assessment suggested an increased incidence for abnormal neurodevelopment in twins B born by PVD.

Clinical indicators associated with the mode of twin delivery: an analysis of 22,712 twin pairs.

OBJECTIVE: To identify clinical indicators associated with the planned and actual mode of delivery in women with a twin pregnancy. STUDY DESIGN: We performed a retrospective cohort study in women with a twin pregnancy who delivered at a gestational age of 32+0-41+0 weeks and days between 2000 and 2008 in the Netherlands. Data were obtained from a nationwide database. We identified maternal, pregnancy-related, fetal, neonatal and hospital-related indicators that were associated with planned cesarean section (CS) and, for women with planned vaginal delivery (VD), for intrapartum CS. The associations between indicators and mode of delivery were studied with uni- and multivariate logistic regression analyses. RESULTS: We included 22,712 women with a twin pregnancy, of whom 4,310 women (19.0%) had a planned CS. Of the 18,402 women who had a planned VD, 14,034 (76.3%) delivered vaginally, 3,545 (19.3%) had an intrapartum CS, while 823 (4.5%) delivered twin A vaginally and twin B by intrapartum CS. The clinical indicators for a planned CS and an intrapartum CS were comparable: non-cephalic position of both twins (aOR 25.32; 95% CI 22.50-28.50, and aOR 21.94; 95% CI 18.67-25.78, respectively), non-cephalic position of twin A only (aOR 21.67 95% CI 19.12-24.34, and aOR 13.71; 95% CI 11.75-16.00, respectively), previous CS (aOR 3.69; 95% CI 3.12-4.36, and aOR 7.00; 95% CI 5.77-8.49, respectively), nulliparity (aOR 1.51; 95% CI 1.32-1.72, and aOR 4.20; 95% CI 3.67-4.81, respectively), maternal age ≥41 years (aOR 3.00; 95% CI 2.14-4.22, and aOR 2.50; 95% CI 1.75-3.59, respectively), and pre-eclampsia (aOR 2.12; 95% CI 1.83-2.46, and aOR 1.34; 95% CI 1.16-1.56, respectively). CONCLUSION: Both planned and intrapartum CS in twins had comparable predictors: non-cephalic position of both twins or twin A only, previous CS, nulliparity, advanced maternal age, and pre-eclampsia.

[Vaginal delivery safe for twins starting at 32 weeks?]. / Vaginale baring veilig voor tweeling vanaf 32 weken?

Compared with other countries, the elective caesarean section rate for twins is relatively low in the Netherlands. Worldwide, there is an increasing trend toward performing more elective caesarean sections for women with a twin pregnancy at term, be it for twins with the first child in breech or in cephalic presentation. The results of the 'Twin Birth Study' indicate that a planned caesarean section does not improve outcome as compared with planned vaginal birth for twins with the first child in cephalic position beyond 32 weeks gestation. During the study, an experienced obstetrician was present during planned vaginal delivery and there was a possibility of performing a secondary caesarean section within 30 minutes. This study provides an additional argument to guarantee the aforementioned conditions in all hospitals where women plan to deliver their twins vaginally. However, the definition of an experienced obstetrician is subject to debate.
