ABSTRACT
BACKGROUND/AIM: The aim of the present retrospective study was to examine the efficiency and safety of the induction of labor with Misoprostol, administered either vaginally or orally. PATIENTS AND METHODS: This retrospective cohort study included pregnant women with a gestational age of ≥36 +0 weeks and a singleton pregnancy who underwent induction of labor with Misoprostol as vaginal insert or as tablet (oral) between January 2014 and January 2019 at the Department of Obstetrics and Gynecology of the University Hospital of Cologne. The objective of this study was to analyze the time until delivery and the maternal and neonatal outcomes. RESULTS: A total of 1,511 patients were included in this retrospective analysis, of whom 1,035 patients (68.5%) underwent induction of labor with a misoprostol vaginal insert (MVI) and 476 (31.5%) with tablets (oral misoprostol: OM). MVI significantly shortened the time from application to delivery (p<0.001) in comparison to OM, reduced the need for epidural anesthesia (EA) (p=0.018) without an increase in caesarean sections (CS) (p=1), ventouse deliveries (VD) (p=0.715), maternal birth injuries or a reduced neonatal outcome (APGAR-Score, umbilical cord pH). CONCLUSION: MVI is superior to OM in terms of efficiency (primary outcome: time from application to delivery) and is equally safe (primary outcome: CS rate). Our study, along with existing literature, highlights the need for further research, particularly regarding neonatal outcomes. Additionally, it underscores the importance of careful consideration when inducing labor and ensuring informed consent.

The complete genome of the potential probiotic Lactiplantibacillus plantarum strain beLP1, isolated from kimchi in South Korea, was sequenced using Illumina and PacBio technologies. The genome comprises one circular chromosome and one plasmid without antimicrobial resistance genes.
ABSTRACT
BACKGROUND/AIM: At the beginning of the 21st century, obstetric medicine took a turn from interventional to restrictive in low-risk birth. The present study examined the changes in peripartum management over the past 20 years at the Women's University Hospital Cologne. The attitudes of the becoming mother and physicians towards anesthesia, episiotomy, and vaginal-operative deliveries were compared and the factors influencing the duration of birth over the past 20 years were examined. PATIENTS AND METHODS: In this retrospective study, the low-risk singleton birth of 955 in 2000/2001 and 944 births in 2018 at the Women's University Hospital Cologne were analyzed. RESULTS: The age of women who tended to give birth has significantly increased at present compared to 20 years ago. In 2018, labor was induced significantly more often than in 2000/2001. The rate of vaginal operative deliveries has fluctuated between 15% and 20% in the last 20 years. Forceps are no longer used. The use of episiotomy has taken a fundamental turn in the last 20 years. Prophylactic episiotomy is not performed anymore, most vaginal operative deliveries take place without the episiotomy. The birth duration has been significantly shortened at present compared to 20 years ago. CONCLUSION: Pregnancy and childbirth over the last years are not considered as a disease, but as a natural course, and the trend of minimizing interventions in low-risk delivery has a positive effect on childbirth.

BACKGROUND/AIM: Due to still controversial discussion regarding appropriate termination of low-risk singleton pregnancies beyond term, this retrospective study aimed to evaluate maternal and perinatal outcomes depending on gestational age and obstetric management. PATIENTS AND METHODS: This is a retrospective cohort analysis including 3.242 low-risk singleton deliveries at the Department of Obstetrics of the University Hospital of Cologne between 2017 and 2022. According to current national guidelines, the cohort was subdivided into three gestational groups, group 1: 40+0-40+6 weeks, group 2: 40+7-40+10 weeks and group 3>40+10 weeks. RESULTS: In our cohort, advanced gestational age was associated with higher rates of secondary caesarean sections, lower rates of spontaneous vaginal deliveries, higher rates of meconium-stained amniotic fluid and depressed neonates with APGAR < 7 after 5 min. Analyzing obstetric management, induction of labor significantly increased the rate of secondary sections and reduced the rate of spontaneous deliveries, while the percentage of assistant vaginal deliveries was independent from obstetric management and gestational age. Induction of labor also significantly enhanced the need for tocolytic subpartu and epidural anesthesia and caused higher rates of abnormalities in cardiotocography (CTG), which also resulted in more frequent fetal scalp blood testing; however, the rate of fetal acidosis was independent of both obstetric management and gestational age. CONCLUSION: Our study supports expectant management of low-risk pregnancies beyond term, as induction of labor increased the rate of secondary sections and did not improve perinatal outcome.

BACKGROUND/AIM: Due to better career opportunities for women and a shift in sex roles, as well as improved reproductive medicine, the age of women who conceive children is rising. A variety of maternal risks and complications that may occur during pregnancy or childbirth in women with advanced maternal age has been examined and reported controversial results. The present study focused on controversial and debatable conclusions regarding the impact of advanced maternal age on maternal and neonatal outcomes. PATIENTS AND METHODS: Data from 8,523 patients, who gave singleton birth at the Women's University Hospital Cologne between 2014 and 2018, were subdivided into two groups: those with maternal age ≥40 years and those <40, and analyzed. RESULTS: A significantly higher rate of C-section, more preterm births, more low birth weight, and higher incidence of retained placenta were observed in women older than or equal to 40. There were no significant differences regarding postpartum hemorrhage and fetal position. Younger patients tend to have more birth injuries and use more epidural administration. The evaluation of neonatal outcomes using fetal base-excess, birth pH, and Apgar score showed no significant clinical differences. CONCLUSION: More antenatal complications could be identified in patients with advanced maternal age. Nonetheless, the neonatal outcomes were comparable and no severe complications in women with advanced maternal age were observed. These findings are due to a well standardized management system for women with risk pregnancies. This encourages better monitoring and care of pregnant women with risk factors.

The endothelial phenotype of tumor blood vessels differs from the liver and forms an important base for endothelium-specific targeting by antibody-coated nanoparticles. Although differences of shear stress and ligand avidity can modulate the nanoparticle binding to endothelium, these mechanisms are still poorly studied. This study analyzed the binding of antibody-coated nanoparticles to tumor and liver endothelium under controlled flow conditions and verified this binding in tumor models in vivo. Binding of anti-CD146-coated nanoparticles, but not of antibody was significantly reduced under increased wall shear stress and the degree of nanoparticle binding correlated with the avidity of the coating. The intravascular wall shear stress favors nanoparticle binding at the site of higher avidity of endothelial epitope which additionally promotes the selectivity to tumor endothelium. After intravenous application in vivo, pegylated self-coated nanoparticles showed specific binding to tumor endothelium, whereas the nanoparticle binding to the liver endothelium was very low. This study provides a rationale that selective binding of mAb-coated nanoparticles to tumor endothelium is achieved by two factors: higher expression of endothelial epitope and higher nanoparticle shearing from liver endothelium. The combination of endothelial marker targeting and the use of shear stress-controlled nanoparticle capture can be used for selective intratumoral drug delivery.
