[Ready to Care for Pregnant Women with Breech Presentation? - Results from an Online Survey for Midwives and Midwifery Students in Germany, Austria, and Switzerland]. / Bereit für die Betreuung von Schwangeren mit Beckenendlage? ­ Ergebnisse aus einer Onlinebefragung für Hebammen und werdende Hebammen in Deutschland, Österreich und der Schweiz.

The vaginal birth of breech presentation is an option for pregnant women supported by current German and international guidelines when favorable conditions and appropriately trained personnel are available. According to midwifery laws in the D-A-CH region, midwives should be able to provide care for a vaginal breech birth in emergencies. Therefore, imparting skills for breech delivery is enshrined in the curriculum for midwifery students. This study evaluated the knowledge and training needs of midwives and midwifery students in the German-speaking region. In May 2022, experiences, specific knowledge, and further training needs regarding vaginal breech birth were assessed through an online survey. Analysis of 467 questionnaires showed that only 30% of respondents currently attend vaginal breech births in their professional environment, but 50% would like to offer this service. 94% of respondents indicated that they would feel more confident if regular training opportunities, particularly simulations and virtual offerings, were provided for vaginal breech birth. However, currently only 10% of respondents receive regular training opportunities for vaginal breech births. The results suggest an increased provision of training opportunities for vaginal breech births to enhance midwives' safety in managing such births.

Lost in translation: Unveiling medical students' untold errors of medical history documentation.

OBJECTIVE: The accurate documentation of a medical history interview is an important goal in medical education. As students' documentation of medical history interviews is mostly decentralised on the wards, a systematic assessment of documentation quality is missing. We therefore evaluated the extent of details missed in students' medical history reports in a standardised setting. METHODS: In this prospective, observational study, 123 of 380 students (32.4%) participated in an Objective Structured Clinical Examination (OSCE) regarding history taking and documentation. Based on the interviews and nine deductively selected main categories, a categorical system was established using a summarising qualitative content analysis. The items in the transcripts (defined as ground truth) and in students' reports were labelled and assigned to the correct subcategory. The ground truth and students' reports were compared to quantify students' documentation completeness. RESULTS: Next to the nine deductively selected main categories, 61 subcategories were defined. A total of 8943 items were labelled in the 123 interview transcripts (ground truth), compared with 5870 items labelled in students' reports (65.6% completeness of students' reports compared with ground truth). The main category personal details overlapped with 94.2% between students' report and ground truth in contrast to the main category with the highest discrepancy, allergy, with 41.1% overlap. Pertinent negative items and non-numerical quantifications were often missed. CONCLUSIONS: Medical students show incomplete documentation of medical history interviews. Therefore, accurate documentation should be taught as an important goal in medical education.

Changes in the rate of preterm infants during the COVID-19 pandemic Lockdown Period-data from a large tertiary German University Center.

PURPOSE: After living with the COVID-19 pandemic for more than 2 years, the impact of lockdown measures on preterm birth rates is inconsistent according to data from different countries. In this study, rates of preterm-born infants during the time of COVID-19-related lockdowns were analyzed in a tertiary perinatal center at Munich University, Germany. METHODS: We analyzed the number of preterm births, infants, and stillbirths before 37 weeks of gestation during the German COVID-19 lockdown period compared to the same time periods in the years 2018 and 2019 combined. Additionally, we expanded the analysis to Pre- and Post-Lockdown Periods in 2020 compared to the respective control periods in the years 2018 and 2019. RESULTS: Our database shows a reduction in the rate of preterm infants during the COVID-19 lockdown period (18.6%) compared to the combined control periods in 2018 and 2019 (23.2%, p = 0.027). This was mainly based on a reduced rate of preterm multiples during the lockdown period (12.8% vs. 28.9%, p = 0.003) followed by a reversed effect showing a threefold rise in multiple births after the lockdown. In singletons, the rate of preterm births was not reduced during the lockdown. The rate of stillbirths was not affected by the lockdown measures as compared to the control period (0.9% vs. 0.7%, p = 0.750). CONCLUSION: During the COVID-19 pandemic lockdown period, we found a reduced rate of preterm-born infants compared to a combined control period in the years 2018 and 2019 in our large tertiary University Center in Germany. Due to the predominant reduction in preterm multiples, we postulate that less physical activity might have led to the protective effect by lockdown measures.

Presentation of ventriculomegaly at 11-14 weeks of gestation: An analysis of longitudinal data.

OBJECTIVES: The aim of this study was to examine the value of the sonographic measurements of the choroid plexus and the lateral ventricles at 11-14 gestational weeks in fetuses that had the diagnosis of second-trimester ventriculomegaly (VM) as a clinical reference. METHODS: The standard axial plane used for biparietal diameter measurement from 2D stored images in the first trimester was used to calculate the ratio between the choroid plexus and lateral ventricle diameter (PDVDR), the choroid plexus and lateral ventricle length (PLVLR) and the choroid plexus and lateral ventricle area (PAVAR) in 100 normal and 15 fetuses diagnosed with second-trimester VM. RESULTS: In fetuses with VM, the measurements of PDVDR, PLVLR and PAVAR were all significantly smaller compared to normal fetuses (p = < 0.001, <0.001, <0.01). Four out of seven cases with mild VM had measurements below the 5th percentile (57%). 75% of cases with moderate or severe VM had at least one measurement below the 5th percentile. CONCLUSIONS: Since the axial plane of the fetal head is obtained in all first-trimester routine screenings, the measurements of PDVDR, PLVLR and PAVAR could easily be integrated into routine examinations for an early detection of VM.

Pelvic inlet area is associated with birth mode.

INTRODUCTION: To determine whether a pelvis is wide enough for spontaneous delivery has long been the subject of obstetric research. A number of variables have been proposed as predictors, all with limited accuracy. In this study, we use a novel three-dimensional (3D) method to measure the female pelvis and assess which pelvic features influence birth mode. We compare the 3D pelvic morphology of women who delivered vaginally, women who had cesarean sections, and nulliparous women. The aim of this study is to identify differences in pelvic morphology between these groups. MATERIAL AND METHODS: This observational study included women aged 50 years and older who underwent a CT scan of the pelvis for any medical indication. We recorded biometric data including height, weight, and age, and obtained the obstetric history. The bony pelvis was extracted from the CT scans and reconstructed in three dimensions. By placing 274 landmarks on each surface model, the pelvises were measured in detail. The pelvic inlet was measured using 32 landmarks. The trial was registered at the German Clinical Trials Register DRKS (DRKS00017690). RESULTS: For this study, 206 women were screened. Exclusion criteria were foreign material in the bony pelvis, unknown birth mode, and exclusively preterm births. Women who had both a vaginal birth and a cesarean section were excluded from the group comparison. We compared the pelvises of 177 women between three groups divided by obstetric history: vaginal births only (n = 118), cesarean sections only (n = 21), and nulliparous women (n = 38). The inlet area was significantly smaller in the cesarean section group (mean = 126.3 cm2 ) compared with the vaginal birth group (mean = 134.9 cm2 , p = 0.002). The nulliparous women were used as a control group: there was no statistically significant difference in pelvic inlet area between the nulliparous and vaginal birth groups. CONCLUSIONS: By placing 274 landmarks on a pelvis reconstructed in 3D, a very precise measurement of the morphology of the pelvis is possible. We identified a significant difference in pelvic inlet area between women with vaginal delivery and those with cesarean section. A unique feature of this study is the method of measurement of the bony pelvis that goes beyond linear distance measurements as used in previous pelvimetric studies.

Online medical history taking course: Opportunities and limitations in comparison to traditional bedside teaching.

Objective: Obtaining a systematic medical history (MH) from a patient is a core competency in medical education and plays a vital role in the diagnosis of diseases. At the Faculty of Medicine at LMU Munich, students have their first course in MH taking during their second year. Due to the COVID-19 pandemic, the traditional bedside MH taking course had to be transformed into an online course (OC). Our objectives were to implement an online MH taking course, to evaluate its feasibility and to compare the evaluation results to a historic cohort that had undertaken the traditional bedside teaching course (BTC). Methods: 874 second-year students participated in the OC (BTC=827). After teaching the theoretical background via asynchronous online lectures, students participated in a practical exercise with fellow students using the video communication platform Zoom where they were able to practice taking a MH on the basis of fictitious, text-based patient cases. Students were then asked to evaluate the course through a standardized online survey with 31 questions on teaching quality and self-perceived learning success, which had also been used in previous years. The survey results were compared to the results of the historic cohort using the Mann-Whitney U test. Results: A total of n=162 students (18.5%) evaluated the OC. In the historic cohort, n=252 (30.5%) completed the survey. 85.3% of the OC respondents thought that the atmosphere during the practical exercise was productive and 83.0% greatly appreciated the flexibility in terms of time management. Moreover, they appreciated the online resources as well as having the opportunity to undertake a MH taking course during the COVID-19 pandemic. 27.7% of the respondents thought that traditional BTCs should be supplemented through more online activities in the future. With respect to the ability of independently taking a MH upon completion of the course, the OC was rated significantly lower relative to the BTC (mean OC=2.4, SD=±1.1 vs. mean BTC=1.9, SD=±1.1 (1=strongly agree; 5=strongly disagree); p<0.0001). Conclusion: OCs are a feasible format and seem to convey the theory and practical implementation in a peer-exercise format of MH taking to medical students. The theoretical background can be acquired with great flexibility. Nevertheless, the students' self-appraisal suggested that the traditional teaching format was more effective at teaching MH taking skills. Thus, we propose a blended learning concept, combining elements of both formats. In this context, we suggest prospective, randomized trials to evaluate blended learning approaches.

Antenatal predictors of stem cell content for successful umbilical cord blood donation.

PURPOSE: The most important HLA-independent factor for the selection of cord blood units (CBU) for hematopoietic stem cell transplantation is the total nucleated cell (TNC) count over 150 × 107 as a surrogate marker for stem cell content. The purpose of this prospective study was to define prenatal clinical predictors for TNC count that would help to identify successful CBU donors before the onset of active labor. METHODS: This was a prospective analysis of 594 CBUs, collected from all eligible term singleton pregnancies at Basel University Hospital between 4/2015 and 9/2016 analyzing several maternal and fetal factors. The impact of these factors on TNC count (< 150 × 107 cells vs. ≥ 150 × 107 cells) of the CBUs was modeled in a multivariate analysis. RESULTS: A total of 114 (19.2%) CBUs had a TNC count of ≥ 150 × 107. In a ROC analysis there was no significant difference between the AUC of all prenatal factors (AUC 0.62) and estimated fetal birth weight by ultrasound alone (AUC 0.62). For women planning a trial of labor a recruitment cut-off at an estimated birth weight of 3300 g would allow 72.6% of all donors with sufficient TNC count to be recruited and 22.8% of all collected CBUs would have a sufficient TNC count for banking. For women planning for elective CS a cut-off of 3400 g would allow 71.4% of all donors with sufficient TNC count to be recruited and 22.7% of all collected CBUs would have sufficient TNC count for banking. CONCLUSION: The estimated fetal birth weight within 2 weeks of delivery by ultrasound as single parameter can be considered at the time of recruitment to estimate the chances of a successful CBU donation.

Simulation of an impacted fetal head extraction during cesarean section: description of the creation and evaluation of a new training program.

Background Although cesarean sections at full dilatation are increasing, training in delivering a deeply impacted fetal head is lacking among obstetricians. The purpose of the study was to implement and evaluate a theoretical and simulation-based training program for this obstetrical emergency. Methods We developed a training program consisting of a theoretical introduction presenting a clinical algorithm, developed on the basis of the available literature, followed by a simulation session. We used the Kirkpatrick's framework to evaluate the program. A questionnaire was distributed, directly before, immediately and 6 weeks after the training. Self-perceived competencies were evaluated on a 6-point Likert scale. Pre- and post-test differences in the Likert scale were measured with the Wilcoxon signed rank test. Additionally, the training sessions were video recorded and rated with a checklist in relation to how well the algorithm was followed. Results Eleven residents and eight senior physicians took part to the training. More than 40% of participants experienced a comparable situation after the course during clinical work. Their knowledge and self-perceived competencies improved immediately after the training program and 6 weeks later. Major improvements were seen in the awareness of the algorithm and in the confidence in performing the reverse breech extraction (14.3% of the participants felt confident with the maneuver in the pre-training assessment compared with 66.7% 6 week post-training). Conclusion Our theoretical and simulation-based training program was successful in improving knowledge and confidence of the participants in delivering a deeply impacted fetal head during a cesarean section performed at full dilation.

Improved Detection Rate of Ovarian Cancer Using a 2-Step Triage Model of the Risk of Malignancy Index and Expert Sonography in an Outpatient Screening Setting.

OBJECTIVE: Preoperative assessment of adnexal masses with ultrasound has been shown to be time-, cost-effective, and specific. When used in combination with the menopausal status and the tumor marker CA125, the risk of malignancy index (RMI) can be calculated, allowing appropriate preoperative triage of patients to a gynecologist or a gynecological oncologist. Moreover, it allows for accurate planning of the required surgical procedure (laparoscopy vs laparotomy). METHODS: A large general gynecologic ultrasonic database retrospectively identified 5218 patients for a 14-year period who presented to the outpatient clinic with an adnexal mass. Additional data (menopausal status, histology, CA125 values) were available in 1108 of these patients. Sensitivity, specificity, positive predictive value, and negative predictive value were calculated. The results were then compared with previously published data from a large Australian gynecological cancer center (GCC, n = 204). RESULTS: With the use of an RMI cutoff of 200, malignant ovarian tumors were correctly triaged to a gynecologic oncologist in 123 of 172 cases, leading to a sensitivity of 72% and specificity of 92% in our general outpatient clinic population compared with a sensitivity of 84% and a specificity of 77% in the GCC high-risk population. The negative predictive value was 95% compared with only 85% in the GCC cohort. We hypothesize that improvement of the overall detection rate of malignancy could be improved from 72% to 85% using a 2-step model, referring patients with an ultrasonic score of 3 to an experienced sonographer who uses pattern recognition. CONCLUSIONS: The RMI is an easy and reliable tool for the accurate triage of adnexal masses. Its value is higher in an unselected gynecological outpatient setting. Our proposed 2-step model including expert pattern recognition could influence particularly the detection rate in borderline and early-stage ovarian cancers and overcome the limitations of the tumor marker CA125.

Unresponsive primipara after rupture of membranes.

Amniotic fluid embolism, also called anaphylactoid syndrome of pregnancy, is a rare but severe problem in obstetrics. It occurs in 8/100,000 births and the maternal mortality is up to 90%. We report the case of a patient with amniotic fluid embolism who was transferred to our hospital. The initial presentation was an unresponsive patient after spontaneous rupture of the membranes. The massive hypotension and coagulopathy as well as fetal bradycardia of 60 bpm led, after stabilisation of the mother, to an emergency caesarean section. The neonate expired hours later, despite neonatological intensive care. During the operation, we had to deal with massive bleeding due to the coagulopathy. Through interdisciplinary teamwork including Bakri postpartum balloon insertion through the obstetrics team, uterine artery embolism by the interventional radiologists and transfusion of blood products, the maternal life was saved and the patient was discharged 9 days after admission.

A new era in prenatal care: non-invasive prenatal testing in Switzerland.

QUESTIONS UNDER STUDY: Prenatal care has been significantly influenced by the introduction of non-invasive prenatal testing (NIPT) for aneuploidies in 2012. The aim of this study was to describe the current impact of NIPT on prenatal care. METHODS: We performed a retrospective data analysis including all women with singleton pregnancies who presented for first trimester screening (FTS) between 1 October 2011 and 30 March 2013 and those seeking NIPT. According to the results of FTS the women were categorised into three risk groups: low risk for aneuploidy (<1:300), intermediate risk (1:300-1:50) and high risk (>1:50). They were counselled about the available options for invasive prenatal testing (IPT) and NIPT available at the time of FTS. The nine months before and after the introduction of NIPT were evaluated regarding further testing after FTS. RESULTS: In total, 951 women were included: 505 examinations (group 1) were carried out before NIPT became available, 446 (group 2) thereafter. In group 2, 9.0% (40/446) had NIPT. Here, 60.0% (24/40) had a low risk according to FTS. In group 2 there was an increase of 3.6% of additional prenatal tests after FTS. The greatest increase was noted in the intermediate-risk category (10.7%). The number of invasive prenatal tests decreased by 67.4%. CONCLUSIONS: We observed a notable increase in prenatal testing after the implementation of NIPT. NIPT is an additional test for women who need more reassurance. Since the options for pregnant women become more complex and the costs of NIPT are high, prenatal counselling has become more challenging.
