Introduction: Breastfeeding to strengthen the immune system suggests allergy prevention as a possible option. The connection between breastfeeding and the development of atopic-allergic diseases is being discussed. The primary aim of this work was to investigate an association of the first early skin-to-skin contact following cesarean section with the development of atopic diseases within the 1st year of life., Methods: The present study was conducted as a bicentric prospective cohort study in central Germany with a 15-month recruitment period. Data collection was by telephone interviews with a follow-up of 12 months. The statistical evaluation procedure was based on a hierarchical test of the association of early skin-to-skin contact between mother and child with the two main outcome measures. The primary outcome is the duration of breastfeeding. The second outcome is the onset of atopic-allergic disease within the 1st year of life., Results: Mothers breastfed longer if they had skin-to-skin contact within the first 30 minutes postpartum [χ²(df=5) = 19.020, p=0.002], if they breastfed their newborns early immediately after birth (p<0.001), and if the first skin-to-skin contact lasted more than one hour [χ²(df=4) = 19.617, p<0.001]. Regarding atopic-allergic diseases, no significant effects of skin-to-skin contact were found in relation to disease development. Regarding breastfeeding, no significant effects of atopic-allergic diseases could be detected either., Conclusions: The results of this study reflect the benefits of skin-to-skin contact in the context of breastfeeding and atopic disease. The current scientific knowledge regarding skin contact and the development of atopic-allergic diseases should be extended and deepened., Competing Interests: The authors have completed and submitted the ICMJE Form for Disclosure of Potential Conflicts of Interest and none was reported., (© 2024 Stephan Y. et al.)

An ideal wound dressing not only needs to absorb excess exudate but should also allow for a moist wound-healing environment as well as being mechanically strong. Such a dressing can be achieved by combining both a natural (alginate) and synthetic (poly(ethylene glycol) polymer. Interestingly, using an electron beam on (meth)acrylated polymers allows their covalent crosslinking without the use of toxic photo-initiators. The goal of this work was to crosslink alginate at different methacrylation degrees (26.1 and 53.5% of the repeating units) with diacrylated poly(ethylene glycol) (PEGDA) using electron-beam irradiation at different doses to create strong, transparent hydrogels. Infrared spectroscopy showed that both polymers were homogeneously distributed within the irradiated hydrogel. Rheology showed that the addition of PEGDA into alginate with a high degree of methacrylation and a polymer concentration of 6 wt/v% improved the storage modulus up to 15,867 ± 1102 Pa. Gel fractions > 90% and swelling ratios ranging from 10 to 250 times its own weight were obtained. It was observed that the higher the storage modulus, the more limited the swelling ratio due to a more crosslinked network. Finally, all species were highly transparent, with transmittance values > 80%. This may be beneficial for the visual inspection of healing progression. Furthermore, these polymers may eventually be used as carriers of photosensitizers, which is favorable in applications such as photodynamic therapy.

Myasthenia gravis is an autoimmune disease with a range of clinical presentations which manifest as combinations of weakness of the ocular, bulbar, and respiratory muscle groups and muscles of the extremities. Young women of reproductive age are most commonly affected. Preconception planning, the impact of pregnancy, prepartum management, drug therapy in pregnancy, myasthenic and cholinergic crises, fetal monitoring, peripartum management including analgesia and anesthesia during labor and cesarean section as well as neonatal management and neonatal myasthenia gravis are described here and the appropriate recommendations are given., Competing Interests: Conflict of Interest/Interessenkonflikt The authors declare that they have no conflict of interest./Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (The Author(s).

The incidence of chronic inflammatory bowel disease (chronic IBD) in persons of reproductive age is high. Chronic IBD does not typically lead to impaired fertility. Nevertheless, the percentage of women suffering from chronic IBD who have children is lower than that of the general population, due to self-imposed childlessness. Providing women with open, unbiased information and, if necessary, helping them to overcome baseless fears should therefore be an essential part of preconception counseling. With the exception of methotrexate, most standard drugs can and should be continued during pregnancy. If the pregnancy occurs during an inactive phase of disease, the rate of complications in pregnancy should, in principle, not be higher than normal. Nevertheless, pregnant women with chronic IBD are classed as high-risk pregnancies. Organ screening in accordance with DEGUM II criteria should be carried out in every case, and women must be monitored for the potential development of placental insufficiency. Any flare-ups which occur during pregnancy should be treated in full. Vaginal delivery can be considered if there is no perianal manifestation of disease; however, the individual risk must be carefully weighed up., Competing Interests: Conflict of Interest/Interessenkonflikt The authors declare that they have no conflict of interest./Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (The Author(s).

Photodynamic treatment is a promising tool for the therapy of multidrug-resistant bacteria. In this study, we highlight photosensitizer-loaded hydrogels as an application system for infected wounds. The poly(ethylene glycol) diacrylate-based and electron beam-polymerized hydrogels were mechanically stable and transparent. They were loaded with two photoactive, porphyrin-based drugs - tetrakis(1 methylpyridinium-4-yl)porphyrin p -toluenesulfonate (TMPyP) and tetrahydroporphyrin - p toluenesulfonate (THPTS). The hydrogels released a sufficient amount of the photosensitizers (up to 300 μmol l -1 ), relevant for efficiency. The antimicrobial effectivity of loaded hydrogels was investigated in a tissue-like system as well as in a liquid system against a multiresistant Escherichia coli . In both systems, light induced eradication was possible. In contrast, hydrogels alone showed only minor antimicrobial activity. Furthermore, the loaded hydrogels were successfully tested against seven multidrug-resistant bacterial strains, namely Enterococcus faecium , Staphylococcus aureus , Klebsiella pneumonia , Acinetobacter baumannii , Pseudomonas aeruginosa , Escherichia coli and Achromobacter xylosoxidans . The eradication of these pathogens, except A. xylosoxidans , was successfully demonstrated. In general, TMPyP-loaded hydrogels were more effective than THPTS-loaded ones. Nevertheless, both photosensitizers displayed effectivity against all investigated bacteria strains. Taken together, our data demonstrate that photosensitizer-loaded hydrogels are a promising new tool to improve the treatment of wounds infected with problematic bacterial pathogens., Competing Interests: There are no conflicts to declare., (This journal is © The Royal Society of Chemistry.)

A major goal of membrane science is the improvement of the membrane performance and the reduction of fouling effects, which occur during most aqueous filtration applications. Increasing the surface hydrophilicity can improve the membrane performance (in case of aqueous media) and decelerates membrane fouling. In this study, a PES microfiltration membrane (14,600 L m -2 h -1 bar -1 ) was hydrophilized using a hydrophilic surface coating based on amide functionalities, converting the hydrophobic membrane surface (water contact angle, WCA: ~90°) into an extremely hydrophilic one (WCA: ~30°). The amide layer was created by first immobilizing piperazine to the membrane surface via electron beam irradiation. Subsequently, a reaction with 1,3,5-benzenetricarbonyl trichloride (TMC) was applied to generate an amide structure. The presented approach resulted in a hydrophilic membrane surface, while maintaining permeance of the membrane without pore blocking. All membranes were investigated regarding their permeance, porosity, average pore size, morphology (SEM), chemical composition (XPS), and wettability. Soxhlet extraction was carried out to demonstrate the stability of the applied coating. The improvement of the modified membranes was demonstrated using dead-end filtration of algae solutions. After three fouling cycles, about 60% of the initial permeance remain for the modified membranes, while only ~25% remain for the reference.

In this study, we highlight hydrogels prepared by electron-beam polymerization. In general, the electron-beam-polymerized hydrogels showed improved mechanical and optical transmittances compared to the conventional UV-cured hydrogels. They were more elastic and had a higher crosslinking density. Additionally, they were transparent over a broader wavelength range. The dependence of the mechanical and optical properties of the hydrogels on the number of single differential and total irradiation doses was analyzed in detail. The hydrogels were prepared for usage as a drug delivery material with methylene blue as a drug model. In the first set of experiments, methylene blue was loaded reversibly after the hydrogel synthesis. Electron-beam-polymerized hydrogels incorporated twice as much methylene blue compared to the UV-polymerized gels. Furthermore, the release of the model drug was found to depend on the crosslinking degree of the hydrogels. In addition, electron-beam polymerization enabled the irreversible binding of the drug molecules if they were mixed with monomers before polymerization.

Purpose: To provide real-world evidence using misoprostol vaginal insert (MVI) for induction of labor in nulliparous and parous women at two German Level I Centers in a prospective observational study., Methods: Between 1 August 2014 and 1 October 2015, eligible pregnant women (≥ 36 + 0 weeks of gestation) requiring labor induction were treated with MVI. Endpoints included time to and mode of delivery rates of tocolysis use, tachysystole, uterine hypertonus or uterine hyperstimulation syndrome and newborn outcomes., Results: Of the 354 women enrolled, 68.9% (244/354) achieved vaginal delivery (nulliparous, 139/232 [59.9%]; parous 105/122 [86.1%]; p < 0.001). Median time from MVI administration to vaginal delivery was 14.0 h (nulliparous, 14.5 h; parous, 11.9 h; p < 0.001). A total of 205/244 (84.0%) and 228/244 (93.4%) women achieved a vaginal delivery within 24 h and 30 h, respectively. The most common indications for cesarean delivery were pathologic cardiotocography (nulliparous, 41/232 [17.4%]; parous, 13/122 [10.7%]; p = 0.081) and arrested labor (dilation or descent; nulliparous, 45/232 [19.4%], parous, 3/122 [2.5%]; p ≤ 0.001). A total of 24.3% of women experienced uterine tachysystole and 9.6% experienced uterine tachysystole with fetal heart rate involvement, neither of which were significantly different for nulliparous and parous women. In total, 42/345 (12.2%) of the neonates had an arterial pH < 7.15 and 12/345 3.5% had a 5-min Apgar score ≤ 7., Conclusion: When clinically indicated, MVI was efficient and safe for induction of labor in women with an unfavorable cervix. Women, however, should be counseled regarding the risk of uterine tachysystole prior to labor induction with MVI.

Purpose: This is an official interdisciplinary guideline, published and coordinated by the German Society of Gynaecology and Obstetrics (DGGG), the Austrian Society of Gynaecology and Obstetrics (OEGGG) and the Swiss Society of Gynaecology and Obstetrics (SGGG). The guideline was developed for use in German-speaking countries and is backed by the German Society of Anaesthesiology and Intensive Medicine (DGAI), the Society of Thrombosis and Haemostasis Research (GTH) and the German Association of Midwives. The aim is to provide a consensus-based overview of the diagnosis and management of peripartum bleeding obtained from an evaluation of the relevant literature., Methods: This S2k guideline was developed from the structured consensus of representative members of the various professional associations and professions commissioned by the Guideline Commission of the DGGG., Recommendations: The guideline encompasses recommendations on definitions, risk stratification, prevention and management.

Background: The combination of the qualitative fetal fibronectin test and cervical length measurement has a high negative predictive value for preterm birth within 7 days; however, positive prediction is poor. A new bedside quantitative fetal fibronectin test showed potential additional value over the conventional qualitative test, but there is limited evidence on the combination with cervical length measurement., Objective: The purpose of this study was to compare quantitative fetal fibronectin and qualitative fetal fibronectin testing in the prediction of spontaneous preterm birth within 7 days in symptomatic women who undergo cervical length measurement., Study Design: We performed a European multicenter cohort study in 10 perinatal centers in 5 countries. Women between 24 and 34 weeks of gestation with signs of active labor and intact membranes underwent quantitative fibronectin testing and cervical length measurement. We assessed the risk of preterm birth within 7 days in predefined strata based on fibronectin concentration and cervical length., Results: Of 455 women who were included in the study, 48 women (11%) delivered within 7 days. A combination of cervical length and qualitative fibronectin resulted in the identification of 246 women who were at low risk: 164 women with a cervix between 15 and 30 mm and a negative fibronectin test (<50 ng/mL; preterm birth rate, 2%) and 82 women with a cervix at >30 mm (preterm birth rate, 2%). Use of quantitative fibronectin alone resulted in a predicted risk of preterm birth within 7 days that ranged from 2% in the group with the lowest fibronectin level (<10 ng/mL) to 38% in the group with the highest fibronectin level (>500 ng/mL), with similar accuracy as that of the combination of cervical length and qualitative fibronectin. Combining cervical length and quantitative fibronectin resulted in the identification of an additional 19 women at low risk (preterm birth rate, 5%), using a threshold of 10 ng/mL in women with a cervix at <15 mm, and 6 women at high risk (preterm birth rate, 33%) using a threshold of >500 ng/mL in women with a cervix at >30 mm., Conclusion: In women with threatened preterm birth, quantitative fibronectin testing alone performs equal to the combination of cervical length and qualitative fibronectin. Possibly, the combination of quantitative fibronectin testing and cervical length increases this predictive capacity. Cost-effectiveness analysis and the availability of these tests in a local setting should determine the final choice., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Worldwide, post-partum haemorrhage (PHH) remains one of the leading causes for maternal mortality. The German Society of Gynaecology and Obstetrics, the German Midwifes' Society, the German Society of Thrombosis and Haemostasis and the German Society of Anaesthesiology and Intensive Care updated the former guideline. The resulting recommendations are the results of a structured literature search and a formal consensus process and contain all aspects of PPH including diagnosis, causes, risk factors and therapy. Key aspect of the anaesthesiological and haemostatic therapies is the development of an interdisciplinary standard operating procedure containing medical options related to the bleeding's cause and severity as well as the surgical option. For suspected PPH, this guideline emphasizes clinical and laboratory-based diagnostics, as only those will enable an early identification of the bleeding's causes and the resulting causative therapy. Recommendations cover evidence-based application of uterotonics for atony as well as tranexamic acid, calcium, factor concentrates and blood products. Additionally, recommendations are given on the topics of cell salvage, controlled hypotension and restrictive transfusion triggers., (© Georg Thieme Verlag Stuttgart · New York.)
