Aim: To evaluate obstetric outcomes in embryo transfer (ET) during estrogen with progestin hormone replacement therapy (HRT) cycles using assisted reproductive technology (ART). Methods: Of the 118 singleton pregnancies conceived with ART and delivered between January 2015 and December 2017, we reviewed the data of 87 cases that had information on HRT at the time of ET. Data on pregnancy outcomes included the presence of small for gestational age fetuses, hypertensive disorders of pregnancy, placenta previa (including low-lying placenta), placental abruption and placenta accreta spectrum (including placenta accreta, placenta increta and placenta percreta). We investigated the relationship between HRT cycles and adverse placental outcomes (placenta accreta spectrum, placental abruption, placenta previa, hypertensive disorders of pregnancy and small for gestational age fetuses). We then analyzed the associations that correlated with adverse placental outcomes. Results: Patients with ET during HRT cycles were more likely to have placenta accreta spectrum. During the study period, 87 out of 118 singleton live births using ART had information on HRT (60 HRT cycles and 27 ovulation cycles). The incidence of placenta accreta spectrum was significantly higher in the HRT cycle group than in the ovulation cycle group (HRT cycle, 31.7% [19 of 60] vs ovulation cycle, 7.4% [2 of 27]; P < 0.01). Conclusion: The obstetric outcomes occurring in pregnancies involving HRT use may differ among ET cycles. ET during HRT cycles were associated with adverse obstetric outcomes due to placenta accreta spectrum. The potential interaction between HRT cycles and adverse placental events is novel and warrants further investigation.

We developed a microfibrous poly(L-lactic acid) (PLLA) nerve conduit with a three-layered structure to simultaneously enhance nerve regeneration and prevent adhesion of surrounding tissue. The inner layer was composed of PLLA microfiber containing 25% elastin-laminin mimetic protein (AG73-(VPGIG)30) that promotes neurite outgrowth. The thickest middle layer was constructed of pure PLLA microfibers that impart the large mechanical strength to the conduit. A 10% poly(ethylene glycol) was added to the outer layer to prevent the adhesion with the surrounding tissue. The AG73-(VPGIG)30 compositing of an elastin-like repetitive sequence (VPGIG)30 and a laminin-derived sequence (RKRLQVQLSIRT: AG73) was biosynthesized using Escherichia coli. The PLLA microfibrous conduits were fabricated using an electrospinning procedure. AG73-(VPGIG)30 was successfully mixed in the PLLA microfibers, and the PLLA/AG73-(VPGIG)30 microfibers were stable under physiological conditions. The PLLA/AG73-(VPGIG)30 microfibers enhanced adhesion and neurite outgrowth of PC12 cells. The electrospun microfibrous conduit with a three-layered structure was implanted for bridging a 2.0-cm gap in the tibial nerve of a rabbit. Two months after implantation, no adhesion of surrounding tissue was observed, and the action potential was slightly improved in the nerve conduit with the PLLA/AG73-(VPGIG)30 inner layer.

Aim: Hypertensive disorders of pregnancy (HDP) are serious conditions that occur in 5-10% of pregnancies. Maternal factors, such as maternal age, obesity, and renal disease, have been described as risk factors. In order to extract the background lifestyle and gynecological characteristics for HDP, we conducted a prospective cohort study. Methods: Pregnant participants were administered a questionnaire on characteristics, menstrual abnormalities and lifestyle factors. The women were followed individually until 1-month postpartum. We used medical records to examine the relationship between menstrual abnormalities and the onset of HDP. Results: We collected data from 193 pregnant women, and excluding 3 who had miscarriage, examined the records of 190. A total of 26 patients developed HDP, of which 10 had early-onset HDP and 16 had late-onset HDP. Although there was no significant association between HDP and dysmenorrhea just prior to pregnancy, there was a significant increase in the incidence of HDP in patients who experienced dysmenorrhea around the age of 20 years (odds ratio 4.362 [95% CI 1.61-11.81]). Conclusion: We found that patients with a history of dysmenorrhea around the age of 20 years have a significantly higher risk of developing HDP. Although dysmenorrhea in young adulthood is ameliorated, it may become apparent as a perinatal disease when a physical load such as pregnancy is applied.

Dieser Beitrag beschäftigt sich mit der Rezeption Jacob Böhmes in dem emblematischen Erbauungsliteratur des niederländischen Dichters Jan Luyken. In seinem Werk Jezus en de Ziel verwendet Luyken, ohne Böhme namentlich zu erwähnen, in erheblichem Maße Passagen aus dessen Schriften. Auf der Basis seiner Kenntnis der mittelalterlichen Mystik, besonders Eckharts und Taulers rezipiert Luyken sowohl Böhmes Gedankengut als auch seine Terminologie. Er verbindet vor allem Böhmes Christologie und Sophiologie mit seinem eigenen Zentralthema, der Pilgerfahrt der Seele zum Himmel. Nach seiner Auffassung soll die Seele in den Himmel gelangen, wobei der Himmel in der Seele selbst liegt. Diese neuartige Konzeption der Pilgerfahrt der Seele ist stark von seiner Böhme-Rezeption beeinflusst.
