Prediction of intrapartum caesarean section in vaginal breech birth: development of models for nulliparous and multiparous women.

OBJECTIVES: To develop prediction models for intrapartum caesarean section in vaginal breech birth. METHODS: This single-center cohort-study included 262 nulliparous and 230 multiparous women attempting vaginal breech birth. For both groups, we developed and (internally) validated three models for the prediction of intrapartum cesarean section. RESULTS: The prediction model for nulliparous women (AUC: 0.67) included epidural analgesia (aOR 2.14; p=0.01), maternal height (aOR 0.64 per 10 cm; p=0.08), birthweight ≥3.8 kg (aOR 2.45; p=0.03) and an interaction term describing the effect of OC if birthweight is ≥3.8 kg (aOR 0.24; p=0.04). An alternative model for nulliparous women which, instead of birthweight, included fetal abdominal circumference with a cut-off at 34 cm (aOR 1.93; p=0.04), showed similar performance (AUC: 0.68). The prediction model for multiparous women (AUC: 0.77) included prelabor rupture of membranes (aOR 0.31; p=0.03), epidural analgesia (aOR 2.42; p=0.07), maternal BMI (aOR 2.92 per 10 kg/m2; p=0.01) and maternal age (aOR 3.17 per decade; p=0.06). CONCLUSIONS: Our prediction models show the most relevant risk factors associated with intrapartum cesarean section in vaginal breech birth for both nulliparous and multiparous women. Importantly, this study clarifies the role of the OC by showing that this parameter is only associated with intrapartum cesarean section if birthweight is above 3.8 kg (or abdominal circumference is above 34 cm). Conversely, knowing the OC when the birthweight is less than 3.8 kg (or abdominal circumference is less than 34 cm) did not improve prediction of this surgical outcome.

Acute Aortic Dissection during Pregnancy: Hideous Clinical Quandaries with Young Lives on the Line-The Role of Hereditary Genetic Syndromes.

Objective: Acute aortic dissection is a rare but frequently fatal aortic catastrophe with high morbidity and mortality. Especially in pregnant patients, acute dissection is often misdiagnosed putting two lives on the line. Due to its scarcity, only case reports have been reported. The aim of this study is to analyze the time of aortic dissection during the course of pregnancy and the outcome of emergency surgery in pregnant women with and without hereditary connective tissue disorder. Methods: We retrospectively reviewed all acute aortic dissections (type A and B) who underwent emergency aortic surgery at our institution between 1994 and 2022 and identified 13 patients with acute aortic dissection during pregnancy or directly postpartum. Mann-Whitney U and Fisher's exact tests were used for statistical analysis. Results: Of the 13 included patients, 5 had a genetic syndrome. These patients were significantly younger at the time of dissection and at an earlier stage of pregnancy (second trimester). Even though operative and in-house mortality was zero, we lost one patient on postoperative day 14 due to rupture of the aortic root after transfer to another hospital. Survival of neonates was 77% including two aborted pregnancies. Conclusions: Surgical treatment of acute aortic dissection during pregnancy can be performed with excellent operative mortality for the mothers and satisfying survival of their neonates. In patients with genetic syndrome, dissection occurs during the early second trimester, whereas non-syndromic patients experience acute dissection in the late third trimester. Long-term follow-up is essential for timely re-intervention, if needed.

The trajectory of body image dissatisfaction during pregnancy and postpartum and its relationship to Body-Mass-Index.

BACKGROUND: During pregnancy, women's bodies undergo rapid body weight and size changes within a relatively short period. Pregnancy may therefore, be associated with an increased vulnerability for developing body image dissatisfaction linked to adverse health outcomes for the mother (e.g., depression, eating disorders) and child (e.g., impaired self-regulation, childhood obesity). The present study aims to examine the prevalence and trajectories of body image dissatisfaction during pregnancy and postpartum and its relationship to pre-pregnancy BMI. This is the first study that investigates prevalence rates of body image dissatisfaction not only ante- but also postpartum, and that compares trajectories of women with normal weight and overweight. METHODS: A prospective longitudinal design with a quantitative approach was applied. Healthy pregnant women (N = 136) answered paper-pencil or online questionnaires at four time points (18th-22nd and 33rd-37th week of gestation, 3 and 6 months postpartum). Body image dissatisfaction was assessed using the German version of the Body Shape Questionnaire (BSQ) and the Eating Disorder Examination Questionnaire (EDE-Q). Both questionnaires are considered reliable and valid measures of several aspects of body image, and the BSQ allows for calculating prevalence rates by providing cut-off values. Using not just one but two body image questionnaires, trajectories of body image dissatisfaction can be compared. Pre-pregnancy BMI was assessed retrospectively via self-reported weight and height. RESULTS: The proportion of women reporting elevated levels of body image dissatisfaction was 6.6% (n = 9) in the second trimester, 2.9% (n = 4) in the third trimester, 11.0% (n = 15) three months postpartum, and 10.3% (n = 14) six months postpartum. Repeated measures ANOVA revealed that body image dissatisfaction significantly decreased from pre-pregnancy to pregnancy, remained stable during pregnancy, and returned to pre-pregnancy levels three to six months postpartum. Mixed between-within ANOVA showed that the overweight/obese group reported significantly higher levels of body image dissatisfaction at each measurement point except during the third trimester than women in the normal weight group. Significant but small interaction effects between time and pre-pregnancy BMI were found. CONCLUSIONS: The results revealed that approximately every tenth woman is affected by body image dissatisfaction after childbirth. Women with a higher BMI level before pregnancy are particularly at risk of experiencing body image dissatisfaction. Healthcare providers should screen for body image dissatisfaction, in particular after childbirth, and inform affected women about possible adverse health outcomes and treatment options. Study limitations concern the drop-out rate of 51.4% and the retrospective and self-reported assessment of pre-pregnancy BMI. Future studies should include additional assessment points in the first trimester and more than six months postpartum and try to include a matched control group of non-pregnant women to compare prevalence rates and trajectory of body image dissatisfaction.

Significance of the sFlt-1/PlGF Ratio in Certain Cohorts - What Needs to be Considered?

The sFlt-1/PlGF ratio is an established tool in clinical practice, where it is part of a diagnostic algorithm and informs the prognosis of preeclampsia (PE). Maternal and gestational comorbidities can affect the performance of the sFlt-1/PlGF ratio and its constituent elements, and a good understanding of the potential pitfalls is required. The objective of this paper was to provide a current narrative review of the literature on the diagnostic and predictive performance of the sFlt-1/PlGF ratio in specific patient cohorts. Potential factors which can negatively affect the clinical interpretability and applicability of the sFlt-1/PlGF ratio include chronic kidney disease, twin pregnancy, and maternal obesity. Pathophysiological mechanisms related to these factors and disorders can result in different concentrations of sFlt-1 and/or PlGF in maternal blood, meaning that the use of standard cut-off values in specific cohorts can lead to errors. To what extent the cut-off values should be adapted in certain patient cohorts can only be clarified in large prospective cohort studies. This applies to the use of the ratio both for diagnosis and prognosis.

[Oncological Disease and Pregnancy Denial: Psychological Support and Interdisciplinary Collaboration]. / Onkologische Erkrankung und Verleugnung einer Schwangerschaft: Psychologische Begleitung und interdisziplinäre Zusammenarbeit.

In the following casuistry, a denied advanced pregnancy was discovered during the diagnosis of an oncological disease. Faced with a life-threatening condition, the patient urged late termination of the pregnancy and was introduced to psychological counselling in order to find a viable and ethically justifiable solution. Strategies for crisis intervention and supportive approaches in the patient's care as well as interdisciplinary collaboration are presented and discussed.

A Single-Centre Retrospective Analysis of Pregnancies with Placenta Accreta Spectrum (PAS): From One-Step Surgery towards Two-Step Surgical Approach.

Background: Placenta accreta spectrum (PAS) can be the cause of major morbidity and its optimal management is still controversial. The aim of this study was to compare the traditional one-step surgery with a two-step surgical approach in which the placenta is left in situ and the second final operation is delayed to minimise blood loss. Methods: We conducted a single-centre retrospective cohort study including all patients managed for PAS between 2007 and 2023. The number of units of red blood cells (RBCs) needed during surgery was the primary outcome used to compare these two approaches. Results: A total of 43 cases were included in this analysis. Twenty of these were managed with the delayed two-step surgical approach, whereas 23 received one-step surgery. The median estimated blood loss during surgery was 2000 mL and 2800 mL for two-step and one-step surgery, respectively (p = 0.095). In the two-step surgical approach, the median number of RBC units transfused during surgery was significantly lower (p = 0.049) and the odds ratio for needing more than four units of RBCs was 0.28 (95%-CI: 0.08-0.98, p = 0.043). A longer interval between the caesarean section and the second operation showed a trend toward lower blood loss (p = 0.065) and was associated with a significantly lower number of RBC units needed during surgery (p = 0.019). Conclusions: Two-step surgery for the treatment of PAS was safe in our cohort and could lead to a reduction in blood transfusion. Leaving the placenta in situ and delaying the final operation represents a possible alternative to traditional caesarean hysterectomy.

LMWH prevents thromboinflammation in the placenta via HBEGF-AKT signaling.

ABSTRACT: Low molecular weight heparins (LMWH) are used to prevent or treat thromboembolic events during pregnancy. Although studies suggest an overall protective effect of LMWH in preeclampsia (PE), their use in PE remains controversial. LMWH may convey beneficial effects in PE independent of their anticoagulant activity, possibly by inhibiting inflammation. Here, we evaluated whether LMWH inhibit placental thromboinflammation and trophoblast NLRP3 inflammasome activation. Using an established procoagulant extracellular vesicle-induced and platelet-dependent PE-like mouse model, we show that LMWH reduces pregnancy loss and trophoblast inflammasome activation, restores altered trophoblast differentiation, and improves trophoblast proliferation in vivo and in vitro. Moreover, LMWH inhibits platelet-independent trophoblast NLRP3 (NLR family pyrin domain containing 3) inflammasome activation. Mechanistically, LMWH activates via heparin-binding epidermal growth factor (HBEGF) signaling the PI3-kinase-AKT pathway in trophoblasts, thus preventing inflammasome activation. In human PE placental explants, inflammasome activation and PI3-kinase-AKT signaling events were reduced with LMWH treatment compared with those without LMWH treatment. Thus, LMWH inhibits sterile inflammation via the HBEGF signaling pathway in trophoblasts and ameliorates PE-associated complications. These findings suggest that drugs targeting the inflammasome may be evaluated in PE and identify a signaling mechanism through which LMWH ameliorates PE, thus providing a rationale for the use of LMWH in PE.

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.

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.

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.

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.

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.

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.

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.

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.

[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.

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.
