RESUMO

This position paper describes clinically important, practical aspects of cervical pessary treatment. Transvaginal ultrasound is standard for the assessment of cervical length and selection of patients who may benefit from pessary treatment. Similar to other treatment modalities, the clinical use and placement of pessaries requires regular training. This training is essential for proper pessary placement in patients in emergency situations to prevent preterm delivery and optimize neonatal outcomes. Consequently, pessaries should only be applied by healthcare professionals who are not only familiar with the clinical implications of preterm birth as a syndrome but are also trained in the practical application of the devices. The following statements on the clinical use of pessary application and its removal serve as an addendum to the recently published German S2-consensus guideline on the prevention and treatment of preterm birth.

RESUMO

Germany faces the challenge of enforcing the academization of midwifery training in the upcoming months in order to comply with Directive 2013/55/EU. This paper outlines the related developments and challenges. At the moment, midwifery training in Germany is still predominantly carried out in technical colleges. In 2019, less than 20% of midwifery training places were college-based. The current standard training is a dual training system which combines vocational training with academic-based courses, but this approach will no longer be feasible once the EU directive has been fully implemented. Although the existing draft legislation completely transfers midwifery training to institutions of higher education, various aspects of this concept have remained vague and do not take account of the laws on higher education in the individual federal states. Moreover, if midwifery training is to be provided by both universities and colleges, this will lead to quite different levels of academization within a relatively small professional group. The concept that universities offer primary qualifications comes closest to the required quality standards for professional, science-based, practical and evidence-based midwifery training.

RESUMO

OBJECTIVE: To examine the effectiveness of the first and second cervical length measurement in the prediction of preterm delivery in symptomatic women with twin pregnancies. METHODS: Retrospective study at the perinatal unit at the University Hospital of Tuebingen, Germany which included women with twin gestations with painful and regular uterine contractions at 24+0 to 33+6 weeks of gestation. The cervical length was measurement at the time of admission and several days later after cessation of the contractions. Treatment included administration of tocolytics (usually oral nifedipine) for no more than 48 hours, and administration of steroids if the cervical length is 25mm or less. The first cervical length measurements were clustered into five groups: measurements of less than 10 mm, between 10.0 and 14.9 mm, between 15.0 and 19.9 mm, between 20.0 and 24.9 mm, and 25 mm or greater. For each group, we calculated the test performance of the cervical length measurements for a delivery within the subsequent seven days and before 34 weeks. To examine the impact of the second cervical length measurement, we used a regression analysis to predict preterm delivery within the next seven days after the second measurement. RESULTS: Our study population consisted of 257 pregnancies. Median maternal and gestational age at the time of admission was 32.0 years and 29.9 weeks' gestation, respectively. 80.2% of the pregnancies were dichorionic-diamniotic. Preterm birth within seven days of admission occurred in 23 (8.9%) pregnancies. 82 (32.9%) patients delivered prior to 34 weeks' gestation. Median cervical length for the entire study population was 17.0 mm. In the cervical length groups <10 mm, 10.0-14.9 mm, 15.0-19.9 mm, 20.0-24.9 mm, and >25.0 mm, delivery within seven days after the initial examination occurred in 29.0%, 10.6%, 4.2%, 6.3% and 0%, respectively. There was a weak but significant association between the cervical length measurements at the time of admission and the time interval between admission and delivery (difference = 27.9 + 0.58 * cervical length, p=0.003, r=0.184). CONCLUSION: We have found that the cervical length can be helpful predicting preterm delivery within seven days of presentation in symptomatic women with twin gestations. However, the test performance is relatively weak. This article is protected by copyright. All rights reserved.

RESUMO

OBJECTIVE: To examine the blood flow in the splenic artery as marker for materno-fetal transmission at about 20 weeks following a maternal first-trimester primary CMV infection. METHODS: This is a retrospective study at the prenatal medicine unit at University of Tuebingen, Germany. Women were included who underwent an amniocentesis to examine the fetal infection status following a maternal primary CMV infection in the first trimester. In all cases, amniocentesis was done at about 20 weeks and at least 6 weeks after the maternal infection. As part of the detailed ultrasound examination prior to each amniocentesis, we examined the peak systolic velocity flow (PSV) and the pulsatility index (PI) of the splenic artery. Measurements were transformed into MoMs according to the normal curves of Ebbing et al. RESULTS: 81 Women fulfilled the inclusion criteria. Maternal and gestational age was 31.9 years and 20.6 weeks' gestation. Maternal-fetal transmission occurred in 13 of the cases. In fetuses without and with a CMV infection, mean PI was 0.98 MoM and 0.89 (p = 0.081). Mean PSV was significantly higher in the group of infected fetuses than in those without (1.24 vs. 0.94 MoM, p = 0.026). CONCLUSION: The PSV may be a marker for maternal-fetal CMV transmission following a first-trimester maternal infection.

RESUMO

PURPOSE: To characterize and understand the demographics (age and body mass index, BMI) of a cohort of women who delivered at a single institution over an 11-year period. The purpose of this analysis is to look for effects over time of demographic characteristics on mode of delivery. METHODS: Retrospective analysis of singleton deliveries between 2004-2014, n = 27,729; level 1 perinatal center, university hospital setting. Data were extracted from the digital birth registry. All statistical analyses were done using R version 3.5.1. Variables analyzed were: age, BMI, and mode of delivery (in the current and any prior pregnancies). RESULTS: Mean age increased from 31.1 ± 5.2 years in 2004 to 31.5 ± 5.0 years in 2014 (p < 0.001, eta2 = 0.0006). Mean BMI before pregnancy increased from 23.7 ± 4.5 to 24.7 ± 5.2 kg/m2. Mean BMI at delivery increased from 28.5 ± 4.7 to 29.6 ± 5.2 kg/m2 (p < 0.001, eta2 = 0.0049). Regarding maternal age, patients with elective Cesarean section (CS) (32.5 ± 5.3 years), emergency CS (31.6 ± 5.6 years) and CS in labor (31.4 ± 5.3 years) were older compared to those with spontaneous (31.0 ± 5.2 years) or instrument-assisted vaginal delivery such as vacuum (31.0 ± 5.0 years) and forceps (30.2 ± 5.4 years). Among the multiparous patients, the mode of delivery in prior pregnancies is the variable with the greatest effect on the mode of delivery in any subsequent pregnancies. The mode of delivery was: spontaneous (55.5%), vaginal operative including vacuum and forceps (8.8%), and Cesarean section (35.7%). CONCLUSIONS: Increase of age and BMI over years is significant, but very small and in a range which seems not clinically relevant. Previous births have the strongest effects on mode of delivery in the current pregnancy.

RESUMO

PURPOSE: It was the aim to evaluate the personal preference of mode of delivery and to analyze differences between medical professionals and non-medical professionals. Interest in participating in a risk stratification system was evaluated. We hypothesized that gaining information about risk stratification provided in the survey could potentially change participants' decision regarding the preferred mode of delivery; therefore, subjects were asked twice (before and after providing information). METHODS: Five cohorts [four professionals (MP) including participants of the German Urogynecology Congress 2017, employees of two major university hospitals in Germany, and members of the German Society of Gynecology and Obstetrics, and one non-professional group (NP) including pregnant women] were invited online to participate in this survey. RESULTS: Vaginal delivery was the preferred mode of delivery in both groups (MP 90.4% vs. NP 88.8%; p = 0.429). MP are more likely to opt for CS due to concerns regarding pelvic floor disorders (MP 56.6% vs. NP 9.1%; p < 0.001). Likewise, parity and prior experienced CS (pCS) had a significant impact on the decision towards vaginal delivery (parity MP OR 7.5 95% CI 4.6-12.3, NP OR 9.3 95% CI 1.9-44.2; (pCS) MP OR 0.12 95% CI 0.07-0.19, NP OR 0.05 95% CI 0.01-0.25). There is great interest in participating in risk stratification systems in the majority of participants (68.9%). CONCLUSIONS: MP and NP prefer vaginal birth for themselves or their partners. Within the group that opted for CS, MP were significantly more often concerned about pelvic floor disorders. Future prevention aspects might include education about pelvic floor disorders.

RESUMO

OBJECTIVE: To compare several strategies for second trimester labor induction for termination of pregnancy (TOP) using misoprostol and mifepristone and to determine which one is more effective in accelerating the time to delivery. METHOD: This was a retrospective study in which pregnancies that underwent second and third trimester TOP due to fetal anomalies between 2007 and 2017 were classified into a group that received misoprostol alone, a group that received mifepristone followed by misoprostol on the same day, one where misoprostol was given 1 day after mifepristone and one where the medications were administered 2 days apart. The primary outcome measure was the induction to delivery interval. RESULTS: 481 pregnancies fulfilled the inclusion criteria. In 140 cases, mifepristone was not administered. 341 women received mifepristone prior to induction, which was administered on the day of induction in 85 cases, and 1 or 2 days prior to induction in 140 and 19 cases. Median time interval between first induction and delivery was 15.0 (IQR 10.0-24.1) h in case no mifepristone was given and 13.2 (9.7-18.2) h if mifepristone was given on the same day and 9.3 (6.6-14.9) and 10.5 (7.2-22.3) h, if mifepristone was given 1 or 2 days prior to induction. After 24 h, the proportion of terminated pregnancies in each of the four groups was 75.0, 83.5, 93.2 and 78.9%. CONCLUSION: A 1 day interval between mifepristone and misoprostol is more effective in second and third trimester TOP compared to other strategies in terms of reducing the induction to abortion interval.

RESUMO

OBJECTIVE: To determine whether screening for trisomy 21 based on first-trimester combined screening (FTCS) with assessment of nasal bone (NB), tricuspid flow (TCF), and ductus venosus flow (DVF) results in similar false-positive rates compared to ultrasound and cell-free DNA (cfDNA) screening. METHODS: This is a subanalysis of a prospective randomized controlled trial which was performed between October 2015 and December 2016. Pregnant women with a normal first-trimester ultrasound examination at 11 to 13 weeks' gestation were randomized into two groups: (1) FTCS with assessment of the NB, TCF, and DVF (extended FTCS [eFTCS]), and (2) ultrasound + cfDNA screening. The false-positive rate in screening for trisomy 21 was defined as the primary outcome parameter. RESULTS: The study population consisted of 688 women in each study arm. In the eFTCS group, the median delta fetal nuchal translucency thickness (NT) was 0.0 mm, free beta-hCG and PAPP-A were 0.96 and 1.11 MoM, and NB, TCF, and DVF PIV were abnormal in 0.9, 0.6, and 7.0% cases. In the ultrasound + cfDNA group, the median delta NT was 0.0 mm. In 10 pregnancies the cfDNA analysis was uninformative and the risk of trisomy 21 was based on eFTCS. There were no false-positive cases in the ultrasound + cfDNA group, whereas the false-positive rates were between 0.9 and 2.2% with eFTCS. CONCLUSION: Screening for trisomy 21 based on ultrasound + cfDNA has a lower false-positive rate than screening based on eFTCS.

RESUMO

PURPOSE: To determine the false-positive rates (FPR) associated with screening for trisomy 18/13 using first-trimester combined screening (FTCS) and an ultrasound plus cfDNA-based approach (US-cfDNA), which includes a detailed ultrasound examination, a cfDNA analysis and a FTCS reflex backup test for cases with uninformative results. METHODS: This is a sub-analysis of a randomized controlled trial, which was performed between 2015 and 2016. Pregnant women with a normal first-trimester ultrasound examination at 11-13 weeks' gestation (NT < 3.5 mm, no anomalies) were randomized into two groups: FTCS and US-cfDNA screening. The overall FPR in screening for trisomies 18/13 and 21 was compared with the FPR in screening for trisomy 21 alone. Pregnancies were considered screen positive if the risk for trisomy 21 was 1:100 and for trisomy 18 and 13, 1:20 each. RESULTS: The study population consisted of 688 pregnancies in each study arm. In the FCTS group, median delta NT was 0.0 mm, free beta-hCG and PAPP-A 0.96 and 1.11 MoM. In the US-cfDNA group, median delta NT was 0.0 mm. In 10 pregnancies, the cfDNA analysis was uninformative. In the FTCS and in the US-cfDNA group, the FPR in screening for trisomy 21 was 2.5% and 0%. In both groups, the overall FPR was not increased by adding screening algorithms for trisomies 18 and 13. CONCLUSION: In conclusion, the addition of screening for trisomies 18 and 13 to screening for trisomy 21 does not significantly change FPR. This is true for both the FTCS and the US-cfDNA-based approach.

RESUMO

BACKGROUND: The preterm birth rate in Germany has remained unchanged at 8-9% since 2009. Preterm birth is the most common cause of neonatal morbidity and mortality. In the absence of a causal treatment, it is important to lower the risk of preterm birth by preventive measures in prenatal outpatient care. METHODS: This review is based on pertinent publications from the years 2000-2019 that were retrieved by a selective search in PubMed. RESULTS: The clinical risk factors for preterm birth-known mainly from retrospective cohort studies-include previous preterm birth (adjusted odds ratio [aOR]: 3.6), multiple pregnancy (relative risk [RR]: 7.7), nicotine consumption (aOR: 1.7), and a short uterine cervix, i.e., <25 mm in the second trimester (aOR: 6.9). In women with a short cervix, vaginally administered progesterone significantly lowers the preterm birth rate (22.5% vs. 14.1% for birth before 33 weeks of gestation, RR: 0.62; 95% confidence interval [0.47; 0.81]). Nicotine abstinence is associated with a lower pre- term birth rate as well (aOR: 0.91; [0.88; 0,.94]), while working more than 40 hours per week (aOR: 1.25; [1,.01; 1,.54]) and heavy lifting during pregnancy (hazard ratio [HR]: 1.43; [1.13; 1.80]) are associated with a higher preterm birth rate. Avoidance of physical exertion, or bed rest, in the face of impending preterm birth does not lower the preterm birth rate, but it does increase the risk of complications, such as thromboembolism. CONCLUSION: The meticulous assessment and elimination of treatable risk factors at the outset of ambulatory prenatal care can help lower the preterm birth rate. Further velopment of causally directed treat- ments (e.g., changes of relevant environmental and epigenetic factors).

RESUMO

Introduction This study investigates whether the time of diagnosis of foetal trisomy 21/18/13 and the frequency of termination of pregnancy have changed in the past 10 years. Material and Methods Retrospective study at the Tübingen University Centre for Women's Health in which the cases with ante- and postnatal diagnosis of trisomy were investigated. A prerequisite was that the patients be examined in the antenatal medicine department. The time of diagnosis, the frequency of termination of pregnancy and the gestational age in the case of a termination were assessed. Results Between 2007 and 2017, trisomy 21/18/13 was diagnosed in 498 foetuses and newborns. In 311 of the foetuses or newborns, trisomy 21 was identified; in 134, trisomy 18; and in 53, trisomy 13. The median gestational age at diagnosis in the case of foetuses with trisomy 21 was between 14.4 and 13.6 weeks of pregnancy. The rate of pregnancy terminations increased slightly from 66.7% between 2007 and 2010 to 75.5% between 2015 and 2017. The median gestational age at the time of termination remained constant at 14.9 and 15.0 weeks of pregnancy respectively. The median gestational age at diagnosis in the case of foetuses with trisomy 18/13 was between 13.6 and 14.6 weeks of pregnancy during the examination period. The percentages of affected pregnancies which were terminated in the three time periods increased slightly from 57.4 to 69.0%. The gestational age remained unchanged in this case at 15.0 and 15.1 weeks of pregnancy respectively. Conclusion The time of intrauterine diagnosis of trisomy 21/18/13 has not changed in the past 10 years. The frequency of termination of a pregnancy increased slightly and the time of termination remained unchanged.

RESUMO

Rhabdomyolysis is a rare clinical condition resulting from severe muscle damage that can cause potentially life-threatening complications. Amongst other causes, muscle compression due to patient positioning during prolonged surgery may result in extensive skeletal muscle breakdown. We report on a 39-year-old nulligravida who developed rhabdomyolysis after prolonged laparoscopic surgery for cervical cancer and adhesions due to deep infiltrating endometriosis. Minimally invasive surgical procedures offer major advantages in gynecologic cancer surgery, and preventive methods provide effective pressure reduction and play a crucial role in avoiding physical harm after surgical positioning. Nevertheless, a combination of surgical and patient-related risk factors may increase the risk of postsurgical onset of rhabdomyolysis. Immediate referral to a specialist center is necessary to ensure prevention of serious complications.

RESUMO

Purpose: Recently, alterations in maternal lipid metabolism were associated with gestational diabetes mellitus (GDM). However, detailed plasma lipid profiles and their relevance for placental and fetal metabolism are currently not understood. Methods: Maternal and placental lipid profiles were characterized in women with GDM and women with normal glucose tolerance (NGT). Inflammatory gene expression was compared in placentas and primary term trophoblasts between the groups. In addition, trophoblasts were stimulated with nonesterified fatty acids (NEFAs), and effects on gene expression were quantified. Finally, placental macrophage content and cord blood concentrations of inflammatory parameters and NEFAs were compared between women with GDM and women with NGT with similar body mass index (BMI). Results: Palmitate and stearate levels were elevated in both maternal plasma and placental tissue of women with GDM. Placental GDM-associated elevations of IL6, IL8, and TLR2 expression were reflected in trophoblasts derived from women with GDM. Stimulation of primary trophoblasts with palmitate led to increased mRNA expression and protein release of the cytokine IL6 and the chemokine IL8. In line with this, elevated amounts of CD68-positive cells were quantified in the placental tissue of women with GDM. No GDM-associated elevations in a range of inflammatory parameters and NEFAs in cord blood of NGT vs GDM neonates was found. Conclusions: GDM, independently of BMI, altered maternal plasma NEFAs and the placental lipid profile. GDM was associated with trophoblast and whole-placenta lipoinflammation; however, this was not accompanied by elevated concentrations of inflammatory cytokines or NEFAs in neonatal cord blood.

RESUMO

PURPOSE: Pregnancy-associated breast cancer (PABC) is considered the second most common malignancy affecting pregnancy. The limited knowledge as to long-term survival is nonuniform. This retrospective study aims to contribute by a follow-up of pregnancies of breast cancer patients treated at a single university centre with focus on maternal long-term survival in relation to time point of diagnosis (before, during, and after pregnancy). METHODS: Data of 25 patients were reviewed for the period between 2000 and 2009 in relation to their neonatal and maternal outcome parameters as well as their maternal breast cancer outcomes by assessing maternal mortality at annual intervals up to a maximum of 10 years follow-up. RESULTS: Median age at diagnosis was 33 years. Maternal survival rate of the total collective came to 76% after 5 years and to 68% after 10 years. The newborns were healthy, 22% of them presented with a 1'Apgar score 5-7. Preterm delivery occurred in 53%. PABC significantly affected maternal survival compared to the national breast cancer cohort at 5 years and barely significantly at 10 years, with highly significant (p < 0.003) to significant (p < 0.01) effects at 5 and 10 years, respectively, for PABC diagnosed during and after pregnancy. CONCLUSIONS: The present findings on survival rates suggest that maternal medical assessment at the beginning of and during further course of pregnancy should include a scrutinized thorough breast examination. Conveying/delivering special competences to monitor these high-risk pregnancies at the interface of oncological care should be considered an obligatory part of academic medical education, obstetrical training and interprofessional midwifery education.

RESUMO

OBJECTIVE: To examine whether in fetuses with trisomy 21 (T21), the ductus venosus (DV) flow differs in presence of a major cardiac defect (congenital cardiac defect [CHD]) and whether this affects the risk distribution in first trimester screening for T21. METHODS: This retrospective study included pregnant women who underwent first trimester screening. This involves an examination of the crown-rump length, the nuchal translucency, the ductus venosus (DV) flow, and the heart. Three groups of fetuses were examined: euploid without CHD, T21 with CHD, and T21 without CHD. We examined the DV pulsatility index for veins, the direction of the a-wave, and ratios of velocities: v/S, v/D, a/S, a/D, and S/D. RESULTS: The study population consisted of 410 euploid fetuses and 136 with T21 (51 with CHD and 85 without CHD). In the 3 groups, the a-wave was reversed in 3.2%, 66.7%, and 57.6%. The DV flow ratios in T21 with and without CDH were significantly different compared with normal fetuses. When comparing the ratios between the 2 T21 groups, only the a/S and a/D ratio were significantly different. The risk distributions in screening for T21 with and without CDH were similar. CONCLUSION: There are some small differences in the DV flow of T21 fetuses with and without CHD, but they are not clinically useful.

RESUMO

The number of pregnancies complicated by gestational diabetes (GDM) is increasing worldwide. To identify novel characteristics of GDM, we studied miRNA profiles of maternal and fetal whole blood cells (WBCs) from GDM and normal glucose tolerant (NGT) pregnant women matched for body mass index and maternal age. After adjustment for maternal weight gain and pregnancy week, we identified 29 mature micro-RNAs (miRNAs) up-regulated in GDM, one of which, i.e., miRNA-340, was validated by qPCR. mRNA and protein expression of PAIP1, a miRNA-340 target gene, was found down-regulated in GDM women, accordingly. In lymphocytes derived from the mothers' blood and treated in vitro, insulin increased and glucose reduced miRNA-340 expression. In fetal cord blood samples, no associations of miRNA-340 with maternal GDM were observed. Our results provide evidence for insulin-induced epigenetic, i.e., miRNA-dependent, programming of maternal WBCs in GDM.
