Relation between socioeconomic status and maternal serum lipids to infant lipid concentrations and anthropometry in the first year of life.

PURPOSE: The physical health and development of an individual are influenced by multiple parameters and shaped by internal and external factors during pregnancy. However, it is unclear whether there is an association between maternal lipid concentrations in the third trimester of pregnancy and infant serum lipids as well as anthropometric growth, and whether these factors are influenced by the socioeconomic status (SES) of the mothers. METHODS: Between 2011 and 2021, 982 mother-child pairs were recruited in the LIFE-Child study. To investigate the influence of prenatal factors, pregnant women at the 24th and 36th week of gestation as well as children at the age of 3, 6 and 12 months were examined and serum lipids determined. Socioeconomic status (SES) was assessed using the validated Winkler Index. RESULTS: A higher maternal BMI was associated with a significantly lower Winkler score and a higher infant weight, height, head circumference and BMI from birth up to the 4th-5th week of life. In addition, the Winkler Index correlates with maternal HDL cholesterol and ApoA1 levels. There was no relation between the delivery mode and the maternal BMI or SES. For the maternal HDL cholesterol concentration in the third trimester, an inverse relation to children's height, weight, head circumference and BMI up to the first year of life as well as the chest and abdominal circumference to an age of 3 months was found. Children born to mothers with dyslipidemia in pregnancy tended to have a worse lipid profile than those born to normolipidemic mothers. CONCLUSION: Serum lipid concentrations and anthropometric parameters of children in the first year of life are affected by multiple factors like maternal BMI, lipid levels and SES.

Anatomy of the fetal membranes: insights from spinning disk confocal microscopy.

PURPOSE: The fetal membranes are essential for the maintenance of pregnancy, and their integrity until parturition is critical for both fetal and maternal health. Preterm premature rupture of the membranes (pPROM) is known to be an indicator of preterm birth, but the underlying architectural and mechanical changes that lead to fetal membrane failure are not yet fully understood. The aim of this study was to gain new insights into the anatomy of the fetal membrane and to establish a tissue processing and staining protocol suitable for future prospective cohort studies. METHODS: In this proof of principle study, we collected fetal membranes from women undergoing vaginal delivery or cesarean section. Small membrane sections were then fixed, stained for nucleic acids, actin, and collagen using fluorescent probes, and subsequently imaged in three dimensions using a spinning disk confocal microscope. RESULTS: Four fetal membranes of different types were successfully processed and imaged after establishing a suitable protocol. Cellular and nuclear outlines are clearly visible in all cases, especially in the uppermost membrane layer. Focal membrane (micro) fractures could be identified in several samples. CONCLUSION: The presented method proves to be well suited to determine whether and how the occurrence of membrane (micro) fractures and cellular jamming correlate with the timing of membrane rupture and the mode of delivery. In future measurements, this method could be combined with mechanical probing techniques to compare optical and mechanical sample information.

Pregnancy induces retinal microvascular changes indicating cardio-metabolic stress.

We performed longitudinal examinations of the arterial retinal microvasculature using Adaptive Optics Retinal Imaging in a 30-year-old healthy woman with twin pregnancy from the 23rd week of gestation (wog) to three days postpartum. Two blinded graders recorded the average wall-to-lumen ratio (WLR) of the examined retinal artery. There was a significant increase in the mean WLR over the course of pregnancy followed by a decreasing WLR from the 37th wog. The demonstrated changes in WLR may be an expression of vascular remodeling and adaptation to volume load which indicates that pregnancy can be viewed as a cardiovascular stress test.

Mechanics of vaginal breech birth: Factors influencing obstetric maneuver rate, duration of active second stage of labor, and neonatal outcome.

BACKGROUND: We investigated possible parameters that could predict the need for obstetric maneuvers, the duration of the active second stage of labor (i.e., the duration of active pushing), and short-term neonatal outcome in vaginal breech births. MATERIALS AND METHODS: We performed a retrospective analysis of 268 successful singleton vaginal breech births in women without previous vaginal births from January 2015 to August 2022. Multivariable regression was used to investigate associations between maternal and fetal characteristics (including antepartum magnetic resonance (MR) pelvimetry) with obstetric maneuvers, the duration of active second stage of labor, pH values, and admission to the neonatal unit. Models for the prediction of obstetric maneuvers were built and internally validated. RESULTS: Obstetric maneuvers were performed in a total of 130 women (48.5%). A total of 32 neonates (11.9%) had to be admitted to the neonatal unit. The intertuberous distance (ITD) (p < 0.001), epidural analgesia (p < 0.001), and birthweight (p = 0.026) were associated with the duration of active second stage of labor. ITD (p = 0.028) and birthweight (p = 0.011) were also independently associated with admission to the neonatal unit, while pH values below 7.10 dropped significantly (p = 0.0034) if ITD was ≥13 cm. Furthermore, ITD (p < 0.001) and biparietal diameter (p = 0.002) were independent predictors for obstetric maneuvers. CONCLUSIONS: ITD is independently associated with the duration of active second stage of labor. Thus, it can predict suboptimal birth mechanics in the last stage of birth, which may lead to the need for obstetric maneuvers, lower arterial pH values, and admission to the neonatal unit. Consequently, MR pelvimetry gives additional information for practitioners and birthing people preferring a vaginal breech birth.

Novel Three-Dimensional Body Scan Anthropometry versus MR-Pelvimetry for Vaginal Breech Delivery Assessment.

In this prospective, monocentric study, we investigated the potency of a novel three-dimensional (3D) body scanner for external pelvic assessment in birth planning for intended vaginal breech delivery. Between April 2021 and June 2022, 73 singleton pregnancies with intended vaginal birth from breech presentation (>36.0 weeks of gestation) were measured using a pelvimeter by Martin, a three-dimensional body scanner, and MR-pelvimetry. Measures were related to vaginal birth and intrapartum cesarean section. A total of 26 outer pelvic dimensions and 7 inner pelvic measurements were determined. The rate of successful vaginal breech delivery was 56.9%. The AUC (area under the curve) of the obstetric conjugate (OC) measured by MRI for predicting the primary outcome was 0.62 (OR 0.63; p = 0.22), adjusted for neonatal birth weight 0.66 (OR 0.60; p = 0.19). Of the 22 measured 3D body scanner values, the ratio of waist girth to maternal height showed the best prediction (AUC = 0.71; OR 1.27; p = 0.015). The best predictive pelvimeter value was the distantia spinarum with an AUC of 0.65 (OR = 0.80). The 3D body scanner technique is at least equal to predict successful vaginal breech delivery compared to MRI diagnostics. Further large-scale, prospective studies are needed to verify these results.

Course of an unplanned and unexpected pregnancy in a 39 year-old patient with Complex bladder extrophy: a case report.

BACKGROUND: With improved operative techniques pregnancy rates have been rising in patients with anomalies of the extrophy-epispadias-complex, including also female patients with bladder extrophy. Specific risks around pregnancy need to be addressed sufficiently beforehand. CASE PRESENTATION: An unplanned pregnancy was detected at 34 weeks in a 39-year old White female patient with former complex bladder extrophy. Decades after her operation she had not received any follow-up medical care and believed to be unable to conceive due to her anomaly. Thus no contraceptive matters were taken. The patient had lived in a stable relationship with regular sexual intercourse for many years. Until 34 weeks the pregnancy was uncomplicated, but then uterine prolapse and signs of beginning pre-eclampsia appeared, and a healthy girl was born with cesarean section. CONCLUSION: As patients with bladder extrophy and other anomalies from the extrophy-epispadias-complex reach adolescence/adulthood, they need continuous medical follow-up and transition of care to adult surgery and gynecology in order to address specific aspects of sexual health, reproduction, contraception, and also cancer screening. In the presented case lack of transition of care resulted in an unplanned and complicated pregnancy.

Bone turnover in lactating and nonlactating women.

PURPOSE: During lactation, bone turnover increases, reflecting the mobilization of Calcium from maternal skeletal stores and resulting in bone loss. However, mechanisms are not yet fully understood, and previous studies have been comparatively small. We aim to assess bone metabolism during lactation by comparing bone-metabolism-related-parameters between large cohorts of lactating and nonlactating women. METHODS: In a retrospective cohort study, we recruited 779 postpartum women and 742 healthy, nonpregnant, nonlactating controls. Postpartum women were examined 3 and 6 months after delivery and retrospectively assigned to either the exclusively breastfeeding (exc-bf) group if they had exclusively breastfed or the nonexclusively breastfeeding (nonexc-bf) group if they had not exclusively breastfed up to the respective visit. Serum levels of PTH, Estradiol, total Calcium, Phosphate, and bone turnover markers (ßCTX, P1NP, Osteocalcin) were compared between the groups. RESULTS: Bone turnover markers were significantly increased in exc-bf and nonexc-bf women compared with the controls (all ps < .001). ßCTX was approximately twice as high in exc-bf women than in the controls. PTH levels were marginally higher in exc-bf (p < .001) and nonexc-bf women (p = .003) compared with the controls (6 months). Estradiol was suppressed in exc-bf women compared with the controls (p < .001, 3 months). CONCLUSION: Exc-bf and even nonexc-bf states are characterized by an increase in bone formation and resorption markers. The PTH data distribution of exc-bf, nonexc-bf, and control groups in the underpart of the reference range suggest that lactational bone loss is relatively independent of PTH.

Association between TGFß1 Levels in Cord Blood and Weight Progress in the First Year of Life.

Transforming growth factor beta-1 (TGFß1) is an adipokine secreted from adipose tissue, placental tissue and immune cells with a role in cell proliferation, cell apoptosis and angiogenic proliferation. The role of TGFß1 in pregnancy and child growth and the source of cord TGFß1 are yet unknown. In this study, we sought to clarify the correlation of TGFß1 levels with parameters of intrauterine growth and child growth during the first year of life, and to determine whether their source is primarily of fetal or maternal origin. Serum samples and anthropometric measurements were obtained from the LIFE Child cohort of 79 healthy mother-child pairs. Measurements were conducted using enzyme-linked immunosorbent assays. Statistical analyses including Mann-Whitney U-test, correlation analyses and linear regression analyses were performed using GraphPad Prism and R. TGFß1 levels were significantly higher in cord than in maternal serum, suggesting a fetal origin. Multivariate regression analyses revealed strong positive associations between cord TGFß1 levels at birth and child weight at U6. Furthermore, cord TGFß1 was significantly correlated with child weight at approximately one year of age. An increase of 10,000 pg/mL in cord TGFß1 concentrations at birth was associated with a higher body weight of 201 g at roughly one year of age when adjusted for sex.

[Acute Fatty Liver of Pregnancy - Case Series]. / Akute Schwangerschaftsfettleber ­ Fallserie einer seltenen Schwangerschaftskomplikation.

With a prevalence of 0,01-0,03%, acute fatty liver in pregnancy (AFLP) is a rare and dangerous complication of pregnancy and is difficult to distinguish from other, sometimes more common, pregnancy diseases such as HELLP syndrome, aHUS and TTP because of its mostly non-specific symptoms. Due to its rarity, AFLP is often not obvious to the obstetrician as a possible differential diagnosis. Yet early diagnosis and the fastest possible delivery is the only causal therapy and is important for the mortality rate. In the present manuscript, the pathophysiology, diagnosis and therapy of acute fatty liver in pregnancy are highlighted for the clinical routine based on case descriptions from three university hospitals, and reference is made to possible findings that are helpful in establishing the diagnosis. The angiogenic preeclampsia marker sFlt-1 plays a role and provides new opportunities to consider pathophysiological approaches.

[Birth in the Midwife-Led Delivery Room of a Perinatal Center - Learning Curve, Outcomes and Benchmark]. / Geburt im hebammengeleiteten Kreißsaal eines Perinatalzentrums ­ Lernkurve, Ergebnisse und Benchmark.

INTRODUCTION: Most births in Germany take place in a clinical setting. Midwife-led units have been offered in Germany since 2003 as an addition to the primarily physician-led obstetric care. The purpose of this study was to analyze differences regarding medical parameters between a midwife-led and a primarily physician-led unit in a level 1 perinatal center. MATERIAL AND METHODS: Between 12/2020 and 12/2021, all births begun in the midwife-led unit were retrospectively analyzed and compared to a physician-led control cohort. Outcome measures were defined as obstetric interventions, delivery mode and duration, delivery position, and maternal and neonatal outcome. RESULTS: The percentage of deliveries started in the midwife-led unit out of the total birth rate was 4.8% (n=132). Most transfers were made for more effective analgesia (52.6%). Among medically indicated transfers (n=30, 39.5%), transfers due to CTG abnormalities and failure to progress in labor after rupture of membranes predominated. 43.9% (n=58) of patients gave birth successfully in the midwife-led unit. The rate of episiotomy was significantly higher in the primarily physician-led unit compared to the successful midwife-led unit (p=0.019). CONCLUSION: Birth in a midwife-led unit within a perinatal center can be considered an equivalent alternative to primarily physician-led birth for low-risk pregnant women.

Interteam PERINAT - interprofessional team collaboration in undergraduate midwifery and medical education in the context of obstetric emergencies: Presentation of simulation scenarios and empirical evaluation results.

To promote the expansion of interprofessional training objectives in the curriculum of health professions curriculum at the Medical Faculty, University of Leipzig, the interprofessional teaching project between the Department of Obstetrics, the Skills and Simulation Centre and the School of Midwifery was selected to promote innovative teaching projects, supported by the University of Leipzig [https://www.stil.uni-leipzig.de/] grant "StiL - Studying in Leipzig". Using scenarios with simulated patients, students were to recall and apply theoretically learned procedures and immediate measures in an obstetric emergency under supervision and to communicate these clearly in the team. Final-year medical students from the Medical Faculty (n=15) and midwifery students (n=17) from the vocational school went through teaching situations together, in which two simulation scenarios (shoulder dystocia and postpartum haemorrhage) were implemented. The aim of the project was to integrate interprofessional collaboration into training and to learn together under simulated conditions in the Skills and Simulation Center protected environment. The following questions was intended to be clarified in the project in addition to the establishment of a sub-professional teaching unit What do students benefit most from in interprofessional teaching units? Are there differences between midwifery and medical students? Is the learning success the same for team-communicative and professional learning goals? To clarify the questions, an evaluation was carried out using an exploratory questionnaire with a Likert scale. All students particularly liked the exchange and contact with other professional groups, the communicative aspect and situational action in unforeseen emergency situations. The participants stated that they had benefited from both interprofessional teaching units, in terms of team communication as well as in professional terms. However, medical students experienced significantly higher cognitive overload regarding prior acquired knowledge compared to vocational midwifery students. Overall, the team communication learning objectives were more difficult to fulfill.

Adipokines in Pregnancy: A Systematic Review of Clinical Data.

Adipokines are signaling proteins involved in metabolic, endocrinological, vascular and immunogenic processes. Associations of various adipokines with not only insulin resistance but also with increased insulin sensitivity, increased systolic blood pressure, and atherosclerosis highlight the significance of adipokines in several components of metabolic syndrome and metabolic diseases in general. As pregnancy presents a unique metabolic state, the role of adipokines in pregnancy, and even in various pregnancy complications, appears to be key to elucidating these metabolic processes. Many studies in recent years have attempted to clarify the role of adipokines in pregnancy and gestational pathologies. In this review, we aim to investigate the changes in maternal adipokine levels in physiological gestation, as well as the association of adipokines with pregnancy pathologies, such as gestational diabetes mellitus (GDM) and preeclampsia (PE). Furthermore, we will analyze the association of adipokines in both maternal serum and cord blood with parameters of intrauterine growth and various pregnancy outcomes.

Protocol for the Phase 2 EDELIFE Trial Investigating the Efficacy and Safety of Intra-Amniotic ER004 Administration to Male Subjects with X-Linked Hypohidrotic Ectodermal Dysplasia.

X-linked hypohidrotic ectodermal dysplasia (XLHED) is a rare genetic disorder characte-rised by abnormal development of the skin and its appendages, such as hair and sweat glands, the teeth, and mucous glands of the airways, resulting in serious, sometimes life-threatening complications like hyperthermia or recurrent respiratory infections. It is caused by pathogenic variants of the ectodysplasin A gene (EDA). Most affected males are hemizygous for EDA null mutations that lead to the absence or inactivity of the signalling protein ectodysplasin A1 (EDA1) and, thus, to the full-blown phenotype with inability to perspire and few if any teeth. There are currently no long-term treatment options for XLHED. ER004 represents a first-in-class protein replacement molecule designed for specific, high-affinity binding to the endogenous EDA1 receptor (EDAR). Its proposed mechanism of action is the replacement of missing EDA1 in yet unborn patients with XLHED. Once bound to EDAR, ER004 activates the EDA/NFκB signalling pathway, which triggers the transcription of genes involved in the normal development of multiple tissues. Following preclinical studies, named-patient use cases demonstrated significant potential of ER004 in affected males treated in utero during the late second and third trimesters of pregnancy. In order to confirm these results, we started the EDELIFE trial, a prospective, open-label, genotype-match controlled, multicentre clinical study to investigate the efficacy and safety of intra-amniotic ER004 administration as a prenatal treatment for male subjects with XLHED. This article summarises the rationale, the study protocol, ethical issues of the trial, and potential pitfalls.

Oral hygiene and oral health behavior, periodontal complaints and oral health-related quality of life in pregnant women.

OBJECTIVES: This questionnaire-based cross-sectional study aimed in the evaluation of oral hygiene and oral health behavior, periodontal complaints and oral health-related quality of life (OHRQoL) in pregnant women in southwest-Saxony, Germany. MATERIALS AND METHODS: Consecutive patients attending the clinics for Obstetrics and Gynecology, Heinrich-Braun-Klinikum Zwickau, Germany, were recruited in the years 2020 and 2021. The evaluation consisted of three parts: (I) dental and oral hygiene behavior, (II) periodontal complaints and (III) German short form of oral health impact profile (OHIP G14) to assess OHRQoL. RESULTS: 853 out of 1056 participants were included in the study. The pregnant women reported that they have received information on oral health during pregnancy more often from gynecologists than from dentists. Slightly more than half of the participants (51.5%) rated to regularly undergo a professional tooth cleaning. Similarly, nearly half of the women stated to perform interdental cleaning (55.8%). The most common periodontal complaint was bleeding of the gums (45.4%). The OHIP G14 findings of all questions as well as sum scores showed a median of 0. Regression analysis revealed that regular professional tooth cleaning was a predictor of better OHRQoL (ß - 0.698, CI95 0.049-1.299; p < 0.04). CONCLUSION: Oral hygiene and oral health behavior of pregnant women in southwest-Saxony requires improvement. While the overall OHRQoL of the cohort was not reduced, professional tooth cleaning and thus professional preventive measures can support OHRQoL during pregnancy. Improved interdisciplinary oral health care concepts for pregnant women should be fostered. These concepts can also positively influence OHRQoL issues.

Course and prediction of body image dissatisfaction during pregnancy: a prospective study.

BACKGROUND: During pregnancy, women`s bodies undergo rapid changes in body weight and body size within a relatively short period of time. Pregnancy may therefore be associated with an increased vulnerability for the development of body image dissatisfaction that has been linked to adverse health outcomes for mother and child. The present study aims to examine changes in body image during pregnancy as well as predictors of body image dissatisfaction. This is the first study using a tailored, multidimensional measure of body image especially developed for the pregnant population. METHODS: A prospective longitudinal design with a quantitative approach was applied. Healthy pregnant women (N = 222) were assessed using standardized instruments at two time points (T1: 18th-22th week of gestation, T2: 33th-37th week of gestation). The impact of demographic, weight- and health-related, behavioral, and psychological factors assessed at T1 on body image dissatisfaction at T1 and T2 was examined using stepwise linear regression analyses. RESULTS: T-tests for paired samples revealed that dissatisfaction with strength-related aspects of body image, dissatisfaction with body parts, and concerns about sexual attractiveness increased significantly from the middle to the end of pregnancy. In contrast, preoccupation with appearance, dissatisfaction with complexion, and prioritization of appearance over function were significantly reduced over time. Stepwise linear regression analyses revealed that factors influencing body image depend on the component of body image investigated. Overall, a low level of self-esteem and a high level of pregnancy-specific worries were risk factors for several components of body image dissatisfaction. Besides these, poor sleep quality, low levels of physical activity, disturbed eating behavior, and higher levels of BMI and weight gain were significant predictors. CONCLUSIONS: The results highlight the multidimensional nature of body image and show positive as well as negative changes during pregnancy. Overall, modifiable psychological, behavioral, and weight-related factors appear relevant to the extent of body image dissatisfaction.

Neonatal admission rate after vaginal breech delivery.

OBJECTIVES: The safest mode of delivery for fetuses in breech presentations is still an ongoing debate. The aim of this study was to analyze neonatal admission rates after vaginal breech delivery and compare it to other modes of delivery in order to counsel pregnant women with breech presentation adequately. METHODS: We performed a retrospective monocentric analysis of all deliveries with singleton pregnancies in breech presentation > 36.0 weeks of gestation between 01/2018-12/2019. Short-term neonatal morbidity data was collected for vaginal delivery and primary as well as secondary cesarean sections from breech presentations. RESULTS: A total of n=41/482 (8.5%) neonates had to be admitted to NICU: vaginal breech delivery n=18/153 (11.8%), primary cesarean section n=9/101 (8.9%, OR 0.73; CI 0.32-1.70; p=0.47), secondary cesarean section n=10/76 (13.2%, OR 1.14; CI 0.50-2.60, p=0.76) and vaginal vertex delivery n=4/152 (2.6%, OR 0.20; CI 0.06-0.51; p=0.005). There was no significant difference in transfer to NICU between all breech position delivery modes. Despite significantly lower pH and 5' APGAR values after vaginal delivery, neonates delivered by primary cesarean section and NICU admission had to be treated there significantly longer (mean 80.9 vs. 174.0 h). No significant difference in terms of ventilation parameters and infections were found between the vaginal delivery, primary and secondary cesarean section from breech presentation. CONCLUSIONS: Vaginal breech delivery does not result in a higher neonatal admission rate in comparison to primary and secondary section. In contrast, there is a shorter NICU duration in case of neonatal admission after vaginal delivery.

Intrahepatic cholestasis of pregnancy resistant to both therapeutic plasma exchange and albumin dialysis.

Intrahepatic cholestasis in pregnancy (ICP) represents, depending on its severity, a serious risk for the fetus. Those cases with unusually high bile acid levels may be resistant to pharmaceutical treatment and can be treated with plasma exchange or albumin dialysis. However, the success rate of these therapeutic options and the factors influencing therapeutic response are unknown. Furthermore, if these options fail to improve ICP and serum bile acid levels are very high (>200 µm/L), there are no clear recommendations when delivery should be planned. Here, we report a patient with severe ICP resistant to both therapeutic plasma exchange and albumin dialysis. Caesarean section was performed at 32 weeks of gestation followed by rapid remission of ICP.

Umbilical Cord Teratoma Presenting as Ruptured Omphalocele.

Congenital mature teratomas of the umbilical cord are extremely rare. We report on a girl who presented with a ruptured omphalocele and a 7 cm mass connected to the umbilicus, which we resected on the first day of life. Histology revealed mature umbilical cord teratoma . On the 29th day of life, a secondary laparotomy was necessary to address the associated intestinal malformations (megaduodenum, stenotic small bowel with duplication and malrotation). After a prolonged hospital stay, we discharged the patient in age-appropriate conditions. Antenatal diagnosis of an umbilical cord tumor can be challenging in the presence of an omphalocele. Given the high prevalence of associated malformations, the finding of umbilical cord teratoma should be followed by a detailed and comprehensive neonatal workup for additional abnormalities.

sFlt-1/PlGF ratio for prediction of preeclampsia in clinical routine: A pragmatic real-world analysis of healthcare resource utilisation.

BACKGROUND: We investigated the impact of the soluble fms-like tyrosine kinase 1 (sFlt-1)/placental growth factor (PlGF) ratio to predict short-term risk of preeclampsia on clinical utility and healthcare resource utilisation using real-world data (RWD), and compared findings with health economic modelling from previous studies. METHODS AND FINDINGS: This retrospective analysis compared data from the German population of a multicentre clinical study (PROGNOSIS, n = 203; sFlt-1/PlGF ratio blinded and unavailable for decision-making) with RWD from University Hospital Leipzig, Germany (n = 281; sFlt-1/PlGF ratio used to guide clinical decision-making). A subgroup of the RWD cohort with the same inclusion criteria as the PROGNOSIS trial (RWD prediction only, n = 99) was also included. sFlt-1/PlGF ratio was measured using fully automated Elecsys® sFlt-1 and PlGF immunoassays (cobas e analyser; Roche Diagnostics). A similar proportion of women in the RWD and PROGNOSIS cohorts experienced preeclampsia (14.95% vs. 13.79%; p = 0.7938); a smaller proportion of women in the RWD prediction only cohort experienced preeclampsia versus PROGNOSIS (6.06%; p = 0.0526). In women with preeclampsia, median gestational age at delivery (weeks) was comparable in the RWD and PROGNOSIS cohorts (34.0 vs. 34.3, p = 0.5895), but significantly reduced in the RWD prediction only cohort versus PROGNOSIS (27.1, p = 0.0038). sFlt-1/PlGF ratio at baseline visit was not statistically significantly different for the RWD and PROGNOSIS cohorts, irrespective of preeclampsia outcome. Hospitalisations for confirmed preeclampsia were significantly shorter in the RWD cohort versus PROGNOSIS (median 1 vs. 4 days, p = 0.0093); there was no significant difference between RWD prediction only and PROGNOSIS (3 days, p = 0.9638). All-cause hospitalisations were significantly shorter in the RWD (median 1 day; p<0.0001) and RWD prediction only (1 day; p<0.0001) cohorts versus PROGNOSIS (3 days). CONCLUSIONS: This study supports the findings of previous studies, showing that routine clinical use of the sFlt-1/PlGF ratio may result in shorter duration of hospitalisations, with potential economic benefits.
