Vaginal dinoprostone insert compared with two different oral misoprostol regimens for labor induction in nulliparous and multiparous women.

INTRODUCTION: Labor induction exhibits considerable variations in protocols and medication regimens. Limited studies compare vaginal dinoprostone inserts with different oral misoprostol dosages, considering parity influence. This study explores the distinctions among 10 mg vaginal dinoprostone inserts and oral misoprostol 25 µg every 2 and every 4 h for labor induction, stratified by parity. MATERIAL AND METHODS: This retrospective cohort study involved 607 participants across two hospitals. The primary outcome, time from induction to delivery, and secondary outcomes, including mode of delivery and maternal and fetal safety, were assessed. RESULTS: Patient characteristics revealed differences in indication for labor induction, with the dinoprostone cohort having fewer post-term and premature rupture of membranes cases but more intrauterine growth restriction/small-for-gestational age. Both oral misoprostol regimens showed a shorter time to delivery interval compared to the dinoprostone cohort (median: 1380 min [IQR 1381.0] and 1127.0 min [IQR 1214.0] vs 1631.5 [IQR 1736.2], p < 0.001 and p = 0.014). Only the difference between oral misoprostol q2h and vaginal dinoprostone remained significant for nulliparous but not multiparous women, losing significance over all the population after adjusting for confounding factors. The proportion of women giving birth within 24 h did not significantly differ between misoprostol q2h and dinoprostone after adjusting for confounders. When comparing misoprostol q4h with dinoprostone after confounder adjustment, an increased time to delivery interval for misoprostol q4h was found (p = 0.001). Both oral misoprostol regimens exhibited fewer meconium-stained liquor (miso q4h: OR 0.44, miso q2h: OR 0.34) and cesarean sections (miso q4h: OR 0.48, miso q2h: OR 0.53) compared to dinoprostone, even after adjustment for confounders. CONCLUSIONS: Our study suggests that oral misoprostol 25 µg q4h is less effective than 10 mg vaginal dinoprostone for labor induction if parity and indication for induction are adjusted for, particularly in multiparous women. In terms of side effects, oral misoprostol regimens seem superior to vaginal dinoprostone. Our data support the individualized use of different agents for labor induction according to parity, indication for induction, bishop score, and women's preference.

The Bern Birth Cohort (BeBiCo) to study the development of the infant intestinal microbiota in a high-resource setting in Switzerland: rationale, design, and methods.

BACKGROUND: Microbiota composition is fundamental to human health with the intestinal microbiota undergoing critical changes within the first two years of life. The developing intestinal microbiota is shaped by maternal seeding, breast milk and its complex constituents, other nutrients, and the environment. Understanding microbiota-dependent pathologies requires a profound understanding of the early development of the healthy infant microbiota. METHODS: Two hundred and fifty healthy pregnant women (≥20 weeks of gestation) from the greater Bern area will be enrolled at Bern University hospital's maternity department. Participants will be followed as mother-baby pairs at delivery, week(s) 1, 2, 6, 10, 14, 24, 36, 48, 96, and at years 5 and 10 after birth. Clinical parameters describing infant growth and development, morbidity, and allergic conditions as well as socio-economic, nutritional, and epidemiological data will be documented. Neuro-developmental outcomes and behavior will be assessed by child behavior checklists at and beyond 2 years of age. Maternal stool, milk, skin and vaginal swabs, infant stool, and skin swabs will be collected at enrolment and at follow-up visits. For the primary outcome, the trajectory of the infant intestinal microbiota will be characterized by 16S and metagenomic sequencing regarding composition, metabolic potential, and stability during the first 2 years of life. Secondary outcomes will assess the cellular and chemical composition of maternal milk, the impact of nutrition and environment on microbiota development, the maternal microbiome transfer at vaginal or caesarean birth and thereafter on the infant, and correlate parameters of microbiota and maternal milk on infant growth, development, health, and mental well-being. DISCUSSION: The Bern birth cohort study will provide a detailed description and normal ranges of the trajectory of microbiota maturation in a high-resource setting. These data will be compared to data from low-resource settings such as from the Zimbabwe-College of Health-Sciences-Birth-Cohort study. Prospective bio-sampling and data collection will allow studying the association of the microbiota with common childhood conditions concerning allergies, obesity, neuro-developmental outcomes , and behaviour. Trial registration The trial has been registered at www. CLINICALTRIALS: gov , Identifier: NCT04447742.

Cervico-vaginal placental α-macroglobulin-1 combined with cervical length for the prediction of preterm birth in women with threatened preterm labor.

INTRODUCTION: Preterm birth is a major cause of neonatal morbidity and mortality. There is an urgent need to accurately predict imminent delivery to enable necessary interventions such as tocolytic, glucocorticoid, and magnesium sulfate administration. We aimed to evaluate placental α-macroglobulin-1 as a new diagnostic marker in the prediction of preterm birth. MATERIAL AND METHODS: We performed a prospective observational trial in women with intact membranes between 24+0 and 36+6 weeks of gestation. We included both women with and without threatened preterm labor symptoms. We evaluated the test performance of placental α-macroglobulin-1 measurements in cervicovaginal fluid regarding three different presentation-to-delivery intervals: ≤2, ≤7, ≤14 days. In addition, we calculated placental α-macroglobulin-1 performance in combination with other prognostic factors such as ultrasonographic cervical length measurements. RESULTS: We included 126 women in the study. We detected high specificity (97%-98%) and negative predictive value (89%-97%) for placental α-macroglobulin-1 at all time intervals. We assessed placental α-macroglobulin-1 in combination with cervical length measurements (≤15 mm) in the sub-group of women presenting with threatened preterm labor symptoms (n = 63) and detected high positive predictive values (100%) for 7- and 14-day presentation-to-delivery intervals. CONCLUSIONS: Our study provides evidence that placental α-macroglobulin-1 testing in cervicovaginal fluid, in combination with cervical length measurements, accurately predicts preterm birth in women with preterm labor symptoms. This novel test combination may be used clinically to triage women presenting with threatened preterm labor, avoiding overtreatment and unnecessary hospitalizations.

Minimally invasive surgery does not impair overall survival in stage IIIC endometrial cancer patients.

PURPOSE: We aimed to evaluate weather survival is impaired in stage IIIC endometrial cancer patients treated with minimally invasive surgery as compared to laparotomy. METHODS: We analyzed surgical data and oncologic outcome of histologically proven stage IIIC endometrial cancer patients who were treated at our institution via laparotomy or via laparoscopic surgery. All the patients underwent a systematic pelvic and para-aortic lymphadenectomy and a complete tumor resection. Perioperative morbidity and overall survival of the patients subjected to the two surgical approaches were compared. RESULTS: Sixty-six patients with stage IIIC endometrial cancer were identified. Of these, 15 patients were operated via laparotomy and 51 via laparoscopy. The two groups were similar with regards to median age at diagnosis, BMI, histotype, number of affected lymph nodes, and median maximal diameter of the affected lymph nodes. Patients undergoing laparoscopic surgery had fewer perioperative complications, a smaller estimated blood loss, and were subjected less frequently to transfusions. Overall survival at 60 months of follow-up did not differ between the two groups. At uni- and multivariate analysis, surgical approach did not affect survival. Only age was a variable associated with overall survival. CONCLUSIONS: Minimally invasive surgery has better perioperative outcomes and does not impair survival in stage IIIC endometrial cancer patients. Age at diagnosis is the only factor independently affecting survival.

Misoprostol vaginal insert versus misoprostol vaginal tablets for the induction of labour: a cohort study.

BACKGROUND: Misoprostol vaginal insert for induction of labor has been recently reported to be superior to dinoprostone vaginal insert in a phase III trial, but has never been compared to vaginal misoprostol in another galenic form. The aim of this study was to compare misoprostol vaginal insert (MVI) with misoprostol vaginal tablets (MVT) for induction of labor in term pregnancies. METHODS: In this retrospective cohort study we compared 200 consecutive women induced with 200-µg misoprostol 24-h vaginal insert (Misodel®) with a historical control of 200 women induced with Misoprostol 25-µg vaginal tablets (Cytotec®) every 4-6 h. Main outcomes variables included induction-to-delivery interval, vaginal delivery within 24-h, incidence of tachysystole, mode of delivery, and neonatal outcome. A subanalysis in the MVI group was performed in order to identify predictive factors for tachysistole and vaginal delivery within 24 h. RESULTS: The time from induction to vaginal delivery was 1048 ± 814 min in the MVI group and 1510 ± 1043 min in the MVT group (p < 0.001). Vaginal delivery within 24-h occurred in 127 (63.5%) patients of the MVI group and in 110 (55%) patients of the MVT group (p < 0.001). Tachysystole was more common in the MVI group (36% vs. 18%; p < 0.001). However, no significant predictors of uterine tachysystole in MVI group have been identified in crude and fully adjusted logistic regression models. Bishop score was the only predictor for vaginal delivery within 24 h (p < 0.001) in MVI group. Caesarean delivery rate (27% vs. 20%) and vaginal-operative deliveries (15.5% vs. 15.5%) did not differ significantly between the two groups. Neonatal outcomes were similar in both groups. CONCLUSIONS: MVI achieves a more vaginal delivery rate within 24 h and Tachysystole events compared to MVT. However, no differences in caesarean section, operative vaginal delivery, and neonatal outcomes are reported. No predictors of tachysistole after MVI administration have been identified. Bishop score and parity are the only predictors of vaginal delivery within 24 h after MVI administration.

SARS-CoV-2 replicates in the placenta after maternal infection during pregnancy.

Objectives: Pregnant women are at increased risk for severe SARS-CoV-2 infection and adverse neonatal outcome, primarily preterm birth and stillbirth. Our study aimed to investigate to which extent SARS-CoV-2 affects placental tissue and if viral replication within the placenta is evident, thus if there is a correlation between placental damage and adverse pregnancy outcome such as stillbirth. Methods: We prospectively collected placentas from 61 SARS-CoV-2 infected pregnant women and 10 controls. Histopathological, immunohistochemical, and in situ hybridization studies were performed on all placentas with antibodies for SARS-CoV-2 proteins, ACE2, various immune cells, and inflammatory markers or probes for SARS-CoV-2 genes and an antisense strand. Results: The measured scores of SARS-CoV-2 glycoprotein, nucleocapsid, and antisense strand indicating replication correlated with both the severity of maternal symptoms and presence of stillbirth. Specifically, 15/61 placentas exhibited replication, while the three cases with stillbirth had high or maximal replication scores. ACE2-H-score was significantly higher in COVID-19 patients, while the expression of various immune cells did not differ statistically. In multivariate analysis, presence of maternal comorbidities correlated with presence of severe COVID-19 infection. Conclusion: We report evidence of active in vivo SARS-CoV-2 replication in the placenta after maternal infection in pregnancy in a case-control setting in a large population. Intensity of placental viral replication as well as viral levels were higher in women with severe or critical COVID-19 disease, supporting the rationale that severity of maternal SARS-CoV-2 infection could correlate with the severity of placentitis. Replication was maximal in cases of stillbirth, which suggests direct placental involvement in the pathophysiology of this dramatic outcome. Continuing to advocate for preventive measures against COVID-19 during pregnancy, including (re)vaccination, as well as appropriately counseling women with diagnosed infection, are of utter importance.

Introducing Artificial Intelligence in Interpretation of Foetal Cardiotocography: Medical Dataset Curation and Preliminary Coding-An Interdisciplinary Project.

Artificial intelligence (AI) is gaining increasing interest in the field of medicine because of its capacity to process big data and pattern recognition. Cardiotocography (CTG) is widely used for the assessment of foetal well-being and uterine contractions during pregnancy and labour. It is characterised by inter- and intraobserver variability in interpretation, which depends on the observers' experience. Artificial intelligence (AI)-assisted interpretation could improve its quality and, thus, intrapartal care. Cardiotocography (CTG) raw signals from labouring women were extracted from the database at the University Hospital of Bern between 2006 and 2019. Later, they were matched with the corresponding foetal outcomes, namely arterial umbilical cord pH and 5-min APGAR score. Excluded were deliveries where data were incomplete, as well as multiple births. Clinical data were grouped regarding foetal pH and APGAR score at 5 min after delivery. Physiological foetal pH was defined as 7.15 and above, and a 5-min APGAR score was considered physiologic when reaching ≥7. With these groups, the algorithm was trained to predict foetal hypoxia. Raw data from 19,399 CTG recordings could be exported. This was accomplished by manually searching the patient's identification numbers (PIDs) and extracting the corresponding raw data from each episode. For some patients, only one episode per pregnancy could be found, whereas for others, up to ten episodes were available. Initially, 3400 corresponding clinical outcomes were found for the 19,399 CTGs (17.52%). Due to the small size, this dataset was rejected, and a new search strategy was elaborated. After further matching and curation, 6141 (31.65%) paired data samples could be extracted (cardiotocography raw data and corresponding maternal and foetal outcomes). Of these, half will be used to train artificial intelligence (AI) algorithms, whereas the other half will be used for analysis of efficacy. Complete data could only be found for one-third of the available population. Yet, to our knowledge, this is the most exhaustive and second-largest cardiotocography database worldwide, which can be used for computer analysis and programming. A further enrichment of the database is planned.

Neurodevelopmental outcomes of infants after in utero exposure to SARS-CoV-2 or mRNA COVID-19 vaccine compared to unexposed infants: a COVI-PREG prospective cohort study.

OBJECTIVES: Data are lacking regarding the long-term consequences of SARS-CoV-2 and COVID-19 mRNA vaccine on infants exposed in utero. We aimed to evaluate the neurodevelopment of infants exposed prenatally to SARS-CoV-2 or mRNA-COVID-19 vaccine during pregnancy at 12 months after birth. METHODS: Infants born from mothers exposed to SARS-CoV-2 or mRNA-COVID-19 vaccine during pregnancy, or unexposed to either the virus or the vaccine were enrolled from 2021 to 2023. Infants with prenatal exposure to the virus or vaccine were compared to infants without prenatal exposure to the virus and/or vaccine. Parents received a neurodevelopmental questionnaire (ASQ-3) at 12 months after birth assessing 5 subdomains: communication, gross motor, fine motor, problem solving and personal social development. A low score was defined as <2 standard deviations below the normative mean in at least one of the subdomains. RESULTS: A total of 330 infants were included (76 in the SARS-CoV-2 group; 153 in the mRNA-COVID-19 vaccine group; 101 in the reference group). In utero exposure to SARS-CoV-2 or mRNA-COVID-19 vaccine were not associated with an increased risk of a low score for at least one subdomain compared to the reference group. The crude odds ratios were 1.16 (95% confidence interval [CI] 0.59-2.28) and 1.04 (95% CI 0.58-1.86), respectively. Results remained consistent in the multivariate analysis, showing no increased risk of a low score for at least one subdomain for infants exposed to SARS-CoV-2 or mRNA-COVID-19 vaccine, compared to the reference group. The adjusted odds ratios were 1.74 (95% CI 0.76-3.99) and 0.76 (95% CI 0.39-1.49), respectively. CONCLUSION: In utero exposure to SARS-CoV-2 or mRNA-COVID-19 vaccine was not associated with an increased risk of a low score for at least one ASQ-3 subdomain at 12 months after birth. Additional studies are needed to confirm our results, especially longer-term evaluation of infant development.

Artificial intelligence and machine learning in cardiotocography: A scoping review.

INTRODUCTION: Artificial intelligence (AI) is gaining more interest in the field of medicine due to its capacity to learn patterns directly from data. This becomes interesting for the field of cardiotocography (CTG) interpretation, since it promises to remove existing biases and improve the well-known issues of inter- and intra-observer variability. MATERIAL AND METHODS: The objective of this study was to map current knowledge in AI-assisted interpretation of CTG tracings and thus, to present different approaches with their strengths, gaps, and limitations. The search was performed on Ovid Medline and PubMed databases. The Preferred Reporting Items for Systematic Reviews and meta-Analysis for Scoping Reviews (PRISMA-ScR) guidelines were followed. RESULTS: We summarized 40 different studies investigating at least one algorithm or system to classify CTG tracings. In addition, the Oxford Sonicaid system is presented because of its wide use in clinical practice. CONCLUSIONS: There are several promising approaches in this area, but none of them has gained big acceptance in clinical practice. Further investigation and refinement of the algorithms and features are needed to achieve a validated decision-support system. For this purpose, larger quantities of curated and labeled data may be necessary.

Risk of congenital malformation after first trimester mRNA COVID-19 vaccine exposure in pregnancy: the COVI-PREG prospective cohort.

OBJECTIVES: This study aimed to evaluate the risk of congenital malformation among pregnant women exposed to the mRNA COVID-19 vaccines during the first trimester of pregnancy, which is a developmental period where the foetus is at risk of teratogenicity. METHODS: Pregnant women were prospectively enrolled from March 2021 to March 2022, at the time of COVID-19 vaccination. Pregnant women exposed to at least one dose of mRNA COVID-19 vaccine from conception to 11 weeks of gestations and 6 days were compared with pregnant women exposed to the vaccine from 12 weeks to the end of pregnancy. The primary outcome was a confirmed congenital malformation at birth. RESULTS: A total of 1450 pregnant women were enrolled including 124 in the first trimester and 1326 in the second and third trimester. The overall proportion of congenital malformation was 0.81% (n = 1/124; 95% CI: 0.02-4.41) and 0.83% (n = 11/1326; 95% CI: 0.41-1.48) among pregnant exposed to the COVID-19 vaccine during the first and second/third trimester, respectively. First trimester exposure was not associated with a higher risk of congenital malformation with a relative risk of 0.89 (95% CI: 0.12-6.80) with no significant changes after adjustment through exploratory analysis. CONCLUSIONS: Pregnant women exposed to mRNA COVID-19 vaccine before 12 weeks of gestation did not have an increased risk of congenital malformation compared with women exposed outside the teratogenic window. Because vaccination is safe and effective, emphasis must be placed on promoting vaccination during pregnancy.

Maternal and perinatal outcomes following pre-Delta, Delta, and Omicron SARS-CoV-2 variants infection among unvaccinated pregnant women in France and Switzerland: a prospective cohort study using the COVI-PREG registry.

Background: SARS-CoV-2 positive pregnant women are at higher risk of adverse outcomes, but little evidence is available on how variants impact that risk. We aim to evaluate maternal and perinatal outcomes among unvaccinated pregnant women that tested positive for SARS-CoV-2, stratified by pre-Delta, Delta, and Omicron periods. Methods: This prospective study enrolled women from March 2020 to September 2022. Exposure to the different SARS-CoV-2 variants was defined by their periods of predominance. The primary outcome was severe maternal adverse outcome defined as either intensive care unit admission, acute respiratory distress syndrome, advanced oxygen supplementation, or maternal death. The secondary outcomes were preterm birth and other perinatal outcomes. Findings: Overall, 1402, 262, and 391 SARS-CoV-2 positive pregnant women were enrolled during the pre-Delta, Delta, and Omicron periods respectively. Severe maternal adverse outcome was reported in 3.4% (n = 947/1402; 95% confidence intervals (95%CI) 2.5-4.5), 6.5% (n = 7/262; 95%CI 3.8-10.2), and 1.0% (n = 4/391; 95%CI 0.3-2.6) of women during the pre-Delta, Delta, and Omicron periods. The risk of severe maternal adverse outcome was higher during the Delta vs pre-Delta period (adjusted risk ratio (aRR) = 1.8; 95%CI 1.1-3.2) and lower during the Omicron vs pre-Delta period (aRR = 0.3; 95%CI, 0.1-0.8). The risks of hospitalization for COVID-19 were 12.6% (n = 176/1402; 95%CI 10.9-14.4), 17.2% (n = 45/262; 95%CI 12.8-22.3), and 12.5% (n = 49/391; 95%CI 9.4-16.2), during the pre-Delta, Delta, and Omicron period, respectively. Pregnancy complications occurred after SARS-CoV-2 exposure in 30.0% (n = 363/1212; 95%CI 27.4-32.6), 35.2% (n = 83/236; 95%CI 29.1-41.6), and 30.3% (n = 105/347; 95%CI 25.5-35.4) of patients during the pre-Delta, Delta, and Omicron periods, respectively. Stillbirths were reported in 0.5% (n = 6/1159; 95%CI 0.2-1.1), 2.8% (n = 6/210; 95%CI 1.0-6.0), and 0.9% (n = 2/213; 95%CI 0.1-3.4) or patients during the pre-Delta, Delta, and Omicron periods respectively. Interpretation: The Delta period was associated with a higher risk of severe maternal adverse outcome and the Omicron period with a lower risk of severe adverse outcome compared to pre-Delta era. The reported risk of hospitalization was high during the Omicron period and should not be trivialized. Funding: Swiss Federal Office of Public Health, Fondation CHUV.

Gestational diabetes is associated with SARS-CoV-2 infection during pregnancy: A case-control study.

AIM: Individuals with SARS-CoV-2 infection and (pre-existing) diabetes, including pregnant women, present with more severe morbidity, as compared to non-diabetic subjects. To date, evidence is limited concerning the role of gestational diabetes (GDM) in severity of SARS-CoV-2 infection during pregnancy, or vice versa. The aim of our study was to investigate the prevalence of GDM in a SARS-CoV-2 infected pregnant population and evaluate risk factors for and from severe infection in these patients. METHODS: A case-control study with prospective data collection for the case group and 1:2 matching with historical controls based on parity, BMI and ethnicity was conducted (n = 224). GDM screening was performed at 26 weeks' gestation. Multivariate binary logistic regression analysis was performed to assess risk factors for GDM and inpatient COVID-19 management. RESULTS: 34.6% of the patients in the case group suffered from GDM, vs. 16.1% in the control group (p = 0.002). 35.7% patients were diagnosed with GDM after, vs. 33.3% before SARS-CoV-2 infection (OR (95%CI) 1.11(0.40-3.08), p = 0.84), with no correlation between time point of infection and GDM diagnosis. SARS-CoV-2 (OR (95%CI) 2.79 (1.42, 5.47), p = 0.003) and BMI (OR (95%CI) 1.12 (1.05, 1.19), p = 0.001) were significant independent risk factors for GDM. CONCLUSION: Data suggests that GDM increases the risk of infection in SARS-CoV-2 infected pregnant women. Meanwhile, SARS-CoV-2 during pregnancy might increase the risk of developing GDM. Vaccination and caution in using protective measures should be recommended to pregnant women, particularly when suffering from GDM.

Low placental weight and altered metabolic scaling after severe acute respiratory syndrome coronavirus type 2 infection during pregnancy: a prospective multicentric study.

OBJECTIVES: A higher risk of adverse pregnancy outcomes is associated with SARS-CoV-2 infection; this could be partially explained by an altered placental function. Because histopathology is often unspecific, we aimed to assess placental weight, birthweight/placental weight (b/p) ratio, and the metabolic scaling exponent ß, an indicator of normal fetal-placental growth, to analyze placental function. METHODS: We included 153 singleton pregnancies with SARS-CoV-2-positive PCR result who delivered at three referring hospitals in Switzerland. Placental weight and b/p ratio were compared to published reference charts. Logistic regression analysis investigated the role of time of infection and other confounding factors on placental weight. The scaling exponent ß was compared to the reference value of 0.75. RESULTS: Placental weight was inferior or equal to the tenth centile in 42.5% (65 of 153) and to the third centile in 19% (29 of 153) of the cases. The risk of low placental weight was not influenced by the trimester in which infection occurred. The b/p ratio was >50th centile in 80.4% (123 of 153) of the cases. The incidence of foetal growth restriction, preeclampsia, and gestational diabetes was 11.8% (18 of 153), 3.3% (5 of 153), and 19.6% (30 of 153). Linear regression modelling revealed a pathologic metabolic scaling exponent ß of 0.871 ± 0.064 (R2 = 0.56). DISCUSSION: SARS-CoV-2 infection during pregnancy was associated with a higher incidence of low placental weight, an increased b/p ratio, and an abnormal scaling exponent ß in our cohort. This could be particularly relevant for the still controversial issue of an increased stillbirth rate in SARS-CoV-2 infection during pregnancy. In this regard, intensified foetal surveillance should be mandatory in these pregnancies.

Mental health in pregnant individuals during the COVID-19 pandemic based on a Swiss online survey.

The aim of our study was to evaluate the mental health of pregnant individuals during the early COVID-19 pandemic and the potential factors associated. A Swiss online survey was proposed to individuals who gave birth during the pandemic period from March 2020. The Edinburgh Postnatal Depression Scale (EPDS), Generalized Anxiety Disorder 7 questions (GAD-7), and Impact Event Scale-Revised (IES-R) were evaluated and used to defined mental health impairment as a composite outcome. From October, 2020 to February, 2021, 736 participants responded. The anxiety GAD-7 score was moderate in 9.6% and severe in 2.0%. The EPDS was moderate in 21.5% and severe in 32.9%. The IES-R was moderate in 10.3% and severe in 3.9%. Mental health impairment was reported in 37.0%. The association between the risk of mental health impairment and foreign nationality was significant (OR = 1.48; 95%CI [1.06-2.05]) as well as fetal and pregnancy worries because of coronavirus (OR = 1.46; 95% CI [1.08-1.98]) and 1.65; 95% CI [1.22-2.24]). Adjusted ORs were significant for foreign nationality (aOR = 1.51; 95%CI [1.07-2.13]) and pregnancy worries because of coronavirus (aOR = 1.62; 95%CI [1.10-2.40]). Pregnant people and especially foreign national have a high risk of mental health impairment during the pandemic.

Obstetrical and Fertility Outcomes Following Transcatheter Pelvic Arterial Embolization for Postpartum Hemorrhage: A Cohort Follow-Up Study.

Objectives: Management of severe postpartum hemorrhage (PPH) includes transcatheter pelvic arterial embolization (TAE). Data regarding subsequent fertility and obstetrical outcomes is limited, as most fertility outcomes derive from TAE in uterine fibroma. The purpose of our study was to evaluate the long-term outcomes of patients undergoing TAE, particularly concerning subsequent fertility and following pregnancies. Material and methods: We included 28 patients who underwent TAE for PPH at our institution between 2009 and 2018 in a retrospective cohort study. Data were assessed by reviewing patients' charts and by contacting the patients. Results: Ten patients had prophylactic balloon occlusion before cesarean section because of anticipated PPH, with planned hysterectomy by placenta increta/percreta. All these patients were excluded from the analysis regarding fertility. 16 (73%) patients reported having regular menstruation after TAE. In total, 11 women had no desire for subsequent pregnancy. Seven of the remaining 11 patients (63.6%) had a total of 13 spontaneous pregnancies, nine of these resulted in miscarriages. Four patients delivered a live baby (36.4%). Two of these (50%) had recurrent PPH and treatment was conservative. Of the patients with infertility (n = 4, 36.4%), two (18.1%) underwent assisted infertility treatment without success. Conclusion: Our study suggests that the fertility of patients undergoing TAE due to PPH is limited. In women who conceive, the risk for first trimester miscarriage as well as recurrent PPH seems to be increased. If this is a consequence of the underlying cause of PPH or the TAE remains unknown. Larger follow-up cohorts are needed. In the meantime, patients who desire pregnancy after TAE should be counseled accordingly.

Evaluation of a Wearable System for Fetal ECG Monitoring Using Cooperative Sensors.

Fetal electrocardiography (fECG) has gotten widespread interest in the last years as technology for fetal monitoring. Compared to cardiotocography (CTG), the current state of the art, it can be designed in smaller formfactor and is thus suited for long-term and unsupervised monitoring. In the present study we evaluated a wearable system which is based on CSEM's cooperative sensors, a versatile technology that allows for the measurement of multiple biosignals and an easy integration into a garment or patch. The system was tested on 25 patients with singleton pregnancies and an age of gestation ≥ 37 weeks. To reject unreliable fetal heart rate (fHR) estimations, the signal processing algorithm provides a signal quality index. In 12 out of 21 patients available for analysis, a good performance of fHR estimations was obtained with a mean absolute error < 5 bpm and an acceptance rate >70%. However, the remaining 9 patients showed low acceptance rates and high errors. Besides investigating the source of these high errors, future work includes the investigating improved signal processing algorithms, different body positions and the use of dry electrodes. Clinical Relevance - The aim of this work is to develop a wearable system that can be offered in hospitals as an alternative to cardiotocography, or as a home monitoring tool for at risk fetuses, in the era of evolving telemedicine.

COVID-19 mRNA vaccine in pregnancy: Results of the Swiss COVI-PREG registry, an observational prospective cohort study.

Background: Pregnant individuals with coronavirus disease 2019 (COVID-19) are at increased risk of severe disease, prematurity, and stillbirth. In March 2021, vaccination for at risk pregnant women was recommended in Switzerland, expanding this to all pregnant women in May 2021. Our aim was to assess the safety of mRNA COVID-19 vaccines in pregnancy. Methods: This multicentre prospective cohort study describes early adverse events and perinatal outcomes in pregnant women who received at least one dose of mRNA vaccine between March 1st and December 27th, 2021 in Switzerland, using the COVI-PREG registry. Early adverse events were collected at least one month following vaccine administration. Pregnancy and neonatal outcomes were extracted from medical records using the maternity discharge letters providing follow-up information up to 5 days after birth. Findings: Of 1012 vaccinated women, 894 (88·3%) received both injections during pregnancy, with BNT162b2 (n = 271) or mRNA-1273 (n = 623) vaccines. Local events (mainly local pain) were reported in 81·3% and 80·5% after the first and second doses. Rates of systemic reactions (mainly fatigue and headache) were similar after the first dose and most frequent after the second dose of mRNA-1273. Of the 1012 women, four (0·4%; 95%CI [0·1-1·0]) severe early adverse events occurred: pulmonary embolism, preterm premature rupture of membranes, isolated fever with hospitalisation, and herpes zoster. Of 107 patients vaccinated before 14 weeks, one (0·9%; 95%CI [0·0-5·1]) early spontaneous abortions was reported (8 weeks). Of 228 vaccinated before 20 weeks one (0·4%; 95%CI [0·0-2·4]) late spontaneous abortion was reported (16 weeks). Of 513 women exposed before 37 weeks, 33 (6·4%; 95%CI [4·5-8·9]) delivered preterm. Among 530 patients exposed in pregnancy, no stillbirth was reported and 25 (4·7%; 95%CI [3·0-6·8]) neonates were admitted to intensive care unit. Interpretation: Frequent local and systemic effects were described after exposure to mRNA COVID-19 vaccines during pregnancy but severe events were rare. Women vaccinated during pregnancy did not experience higher adverse pregnancy or neonatal outcomes when compared to historical data on background risks in the obstetric population. Funding: This research was funded by a grant from the Swiss Federal Office of Public Health and the CHUV Foundation.

Artificial Intelligence for Hospital Health Care: Application Cases and Answers to Challenges in European Hospitals.

The development and implementation of artificial intelligence (AI) applications in health care contexts is a concurrent research and management question. Especially for hospitals, the expectations regarding improved efficiency and effectiveness by the introduction of novel AI applications are huge. However, experiences with real-life AI use cases are still scarce. As a first step towards structuring and comparing such experiences, this paper is presenting a comparative approach from nine European hospitals and eleven different use cases with possible application areas and benefits of hospital AI technologies. This is structured as a current review and opinion article from a diverse range of researchers and health care professionals. This contributes to important improvement options also for pandemic crises challenges, e.g., the current COVID-19 situation. The expected advantages as well as challenges regarding data protection, privacy, or human acceptance are reported. Altogether, the diversity of application cases is a core characteristic of AI applications in hospitals, and this requires a specific approach for successful implementation in the health care sector. This can include specialized solutions for hospitals regarding human-computer interaction, data management, and communication in AI implementation projects.

Unilateral versus bilateral lymph-nodal metastases and oncologic outcome in vulvar cancer patients.

PURPOSE: To evaluate the difference in oncologic outcome between vulvar cancer patients with uni- and bilateral inguino-femoral lymph nodal involvement and to identify factors affecting their oncologic outcome MATERIALS AND METHODS: Patients who underwent inguino-femoral lymphadenectomy for vulvar cancer were classified into three groups according to their lymph nodal status at the histology analysis (negative, positive one side, positive bilaterally). PFS and OS survival were calculated using the Kaplan-Meier method. Univariate and multivariate analyses were performed to analyze factors predicting overall survival and progression-free survival. Multivariable models were used for variables reporting a p value ≤ 0.1 at the univariate analysis. p values ≤ 0.05 were considered statistically significant. RESULTS: One hundred and forty-six patients were considered for the analysis. Patients with bilaterally negative lymph nodes had significantly longer PFS and OS as compared to patients with unilateral and bilateral involvement. Patients with unilateral lymph nodal involvement had better PFS than patients with bilateral lymph nodal involvement. Among these patients, the difference in the OS approached but did not reach statistical significance. At the multivariate analysis, the tumor size affected PFS and lymph nodal involvement affected OS. CONCLUSION: Vulvar cancer patients with bilateral positive lymph nodes have worse oncologic outcome as compared to patients with unilateral lymph nodal involvement; similarly, patients with unilateral lymph nodal involvement have worse oncological outcome as compared to patients with bilateral negative lymph nodes. Furthermore, tumor size and lymph nodal status are independent factors predicting recurrence rate and overall survival, respectively.

Obstetric complications after laparoscopic excision of posterior deep infiltrating endometriosis: a case-control study.

OBJECTIVE: To study obstetric outcomes and complications in women with previously excised posterior deep infiltrating endometriosis (DIE) in comparison with women without endometriosis. DESIGN: Matched case-control study. SETTING: Tertiary-level academic center. PATIENT(S): All surgeries for endometriosis performed in the Department of Gynecology and Gynecological Oncology, University of Bern between March 2004 and July 2015, were assessed. Inclusion criteria included complete laparoscopic excision of posterior DIE. Exclusion criteria included concomitant hysterectomies, refusal to participate, and patients lost to follow-up. Each subsequent pregnancy was matched to three controls by maternal age, parity, history of cesarean, and mode of conception. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Obstetric complications. RESULT(S): Among 841 patients with surgically diagnosed endometriosis, 125 satisfied the inclusion and exclusion criteria. Of these, 73 pregnancies resulted, although a further 11 patients were excluded owing to early miscarriages or extrauterine pregnancies. The final study cohort included 62 singleton pregnancies matched to 186 controls. The analysis identified an increased risk of placenta previa, gestational hypertension, and intrauterine growth restriction for the case group. The possibility of successful vaginal delivery was similar between groups. Moreover, no significant increase in risk of maternal and neonatal delivery complications, except for a slightly higher postpartum blood loss in the case group, was observed. CONCLUSION(S): Despite previous surgical excision, women with history of DIE present a higher risk of placenta previa, gestational hypertonia, and intrauterine growth restriction during pregnancy. Previous surgery for DIE does not seem to predispose to failed vaginal delivery.
