RESUMEN
BACKGROUND: Aneurysmal subarachnoid hemorrhage (SAH) often leads to poor outcome. The aim of the study was to assess platelet function in patients after SAH. METHODS: In this prospective observational study in patients suffering from SAH, platelet count and aggregability were assessed by multiple electrode aggregometry (MEA) over 14 days. RESULTS: In 12 of 18 patients, cerebral vasospasms (CVS) were diagnosed; of those, five developed delayed cerebral ischemia (DCI). We observed a significant increase in the platelet count compared to baseline from day 8 onwards (p < 0.037) and, in patients with CVS and DCI, a significant difference in outcome classified by the mRS (p = 0.047). Repeated measures ANOVA determined no differences in platelet aggregability in patients with or without CVS/DCI. CONCLUSIONS: Besides an increase in platelet count, we detected no increase in platelet aggregability. Nevertheless, patients after SAH may have increased platelet aggregability, which is not reflected by MEA.

BACKGROUND: Since 2009, IPF patients across Europe are recruited into the eurIPFreg, providing epidemiological data and biomaterials for translational research. METHODS: The registry data are based on patient and physician baseline and follow-up questionnaires, comprising 1700 parameters. The mid- to long-term objectives of the registry are to provide clues for a better understanding of IPF phenotype sub-clusters, triggering factors and aggravating conditions, regional and environmental characteristics, and of disease behavior and management. RESULTS: This paper describes baseline data of 525 IPF subjects recruited from 11/2009 until 10/2016. IPF patients had a mean age of 68.1 years, and seeked medical advice due to insidious dyspnea (90.1%), fatigue (69.2%), and dry coughing (53.2%). A surgical lung biopsy was performed in 32% in 2009, but in only 8% of the cases in 2016, possibly due to increased numbers of cryobiopsy. At the time of inclusion in the eurIPFreg, FVC was 68.4% ± 22.6% of predicted value, DLco ranged at 42.1% ± 17.8% of predicted value (mean value ± SD). Signs of pulmonary hypertension were found in 16.8%. Steroids, immunosuppressants and N-Acetylcysteine declined since 2009, and were replaced by antifibrotics, under which patients showed improved survival (p = 0.001). CONCLUSIONS: Our data provide important insights into baseline characteristics, diagnostic and management changes as well as outcome data in European IPF patients over time. TRIAL REGISTRATION: The eurIPFreg and eurIPFbank are listed in ClinicalTrials.gov( NCT02951416 ).

INTRODUCTION: 3-4% of pregnant women present with a fetal breech position at term. National societies regard vaginal breech delivery as a safe option, but only for a specific and thoroughly counseled group of patients. To avoid adverse outcome, many practitioners recommend elective cesarean section once their patients go past the estimated due date. Since encompassing evidence is missing, the evaluation on this common clinical practice is needed. OBJECTIVE: This study compares the short-term maternal and fetal outcome in intended vaginally breech deliveries before the estimated due date (until 40 0/7 weeks of gestation) to the outcome of deliveries carried out past the estimated due date (later than 40 0/7 weeks of gestation). METHODS: This prospective cohort study includes 827 women who presented for an intended vaginal breech delivery of a singleton at our perinatal center between January 2010 and December 2016. RESULTS: 447 patients (54%) delivered before or at their estimated due date, 380 (46%) of pregnancies continued after the estimated due date. Comparing both groups, no significant difference in maternal and neonatal short-term mortality and morbidity was found. The rate of caesarian sections was increased in the group of patients, who delivered later than 40 1/7 weeks of gestation. Here, the likelihood for delivery maneuvers was also increased. CONCLUSION: This study provides evidence, that an elective cesarean section for breech presentations at term is not obligatory when the estimated due date has passed in singleton pregnancy.

INTRODUCTION: The best way to deliver a term breech infant is still a much discussed topic among obstetricians. The question whether nulliparity should be considered an exclusion criterion for an intended vaginal breech delivery is not fully answered. OBJECTIVE: We compared maternal and neonatal outcome of intended vaginal breech deliveries of nulliparous versus multiparous women at term. STUDY DESIGN: We conducted a prospective case-control study between January 2004 and December 2016. 1046 women expecting singletons at term with favorable pelvic measurements were enrolled in the study. RESULTS: Neonatal morbidity and mortality was not significantly different in deliveries of nulliparous (n = 647) versus multiparous (n = 399) women. Nulliparous women had a significantly higher rate of a cesarean section during labor than multiparous women. Maternal birth-injury rates and the use of epidural anesthesia were significantly higher comparing vaginal births of nulliparous (n = 384) versus multiparous (n = 331) women. CONCLUSION: Nulliparity seems not be an exclusion criterion for intended vaginal breech birth at term. It is still important to inform the women of an increased risk of a cesarean section during labor. A clinical management built on this evidence might reduce negative implications for future pregnancies.

Tick-borne encephalitis (TBE) is an emerging infectious disease in large parts of Europe and Asia. Whereas other members of the Flaviviridae family can harm fetal development, there are only very few reports on TBE virus (TBEV) infections during pregnancy. Thus, the implications for fetal health remain largely unknown. In this study, we present detailed pre- and postnatal health assessment of three children in the context of severe maternal TBEV infection during pregnancy. Following acute TBEV infection of the mothers, intrauterine growth and development of all children were assessed by repetitive prenatal ultrasound. Postnatal examinations included clinical and virological analyses over a follow-up period of 18 months. Prenatally, no signs of intrauterine growth restrictions were observed. All neonates were delivered at term. Umbilical cord blood of the newborns tested negative for TBEV RNA. Virus-specific IgG antibodies were positive at birth but negative at 9 and 11 months of age. Importantly, IgM antibodies remained negative throughout the period of observation. Taken together, these clinical and virological data strongly suggest that fetal TBEV infection did not occur, despite severe manifestations in the mothers.

INTRODUCTION: Vaginal delivery out of a breech presentation in pregnancies at term are being re-implemented into clinical practice. Still, recommendations regarding exclusion criteria leading to caesarean sections are based on expert opinions, not on evidence-based guidelines. The difference in perinatal outcome and course of delivery in births with babies in frank breech position and babies in incomplete or complete breech presentation never has been investigated in a large patient cohort. OBJECTIVE: To compare perinatal outcome of vaginally intended breech deliveries between births out of frank breech position and incomplete/complete breech presentation. DESIGN: Prospective cohort study. SAMPLE: 884 women at term with a singleton in frank breech presentation (FB) and 284 women with incomplete or complete breech presentation (CB) intending vaginal birth between January 2004 and December 2018. METHODS: Maternal and fetal outcome was compared between groups using Pearson's Chi Square test. Birth duration parameters were analysed using logistic regression. RESULTS: There were no differences in cesarean section rates (FB: 25.1%, CB 22.2%, p = 0.317). Short-term fetal morbidity did not differ between groups (FB: 2.5%, CB: 2.8%, p = 0.761). In vaginal deliveries the necessity to perform manual assistance was significantly more frequent in deliveries of infants in CB (FB: 39.9%, CB: 51.6%, p = 0.0013). Cord loops (FB: 10.1%, CB: 18.0%, p = 0.0004) and cesarean sections necessary because of cord prolapses (FB: 1.4%, CB 8.1%, p = 0.005) were significantly more often in deliveries with babies in CB. CONCLUSION: This study provides evidence, that perinatal morbidity is not associated with the fetal leg posture in vaginally intended breech deliveries. The higher risk for the need of manual assistance during vaginal birth in deliveries of babies out of complete or incomplete breech presentation suggests that obstetrical departments re-implementing the vaginal breech in their repertoire might start with births of babies out of frank breech presentation.

INTRODUCTION: The clinical management of breech presentations at term is still a controversially discussed issue among clinicians. Clear predictive criteria for planned vaginal breech deliveries are desperately needed to prevent adverse fetal and maternal outcomes and to reduce elective cesarean section rates. The green-top guideline considers an estimated birth weight of 3.8 kg or more an indication to plan a cesarean section despite the lack of respective evidence. OBJECTIVE: To compare maternal and neonatal outcome of vaginal intended breech deliveries of births with children with a birth weight of 2.5 kg- 3.79 kg and children with a birth weight of 3.8 kg and more. DESIGN: Prospective cohort study. SAMPLE: All vaginal intended deliveries out of a breech position of newborns weighing between 2.5 kg and 4.5 kg at the Obstetrics department at Goethe University Hospital Frankfurt from January 2004 until December 2016. METHODS: Neonatal and maternal outcome of a light weight group (LWG) (< 3.8 kg) was compared to and a high weight group (HWG) (≥ 3.8 kg) using Pearson's Chi Square test and Fishers exact test. A logistic regression analysis was performed to detect an association between cesarean section rates, fetal outcome and the birth weight. RESULTS: No difference in neonatal morbidity was detected between the HWG (1.8%, n = 166) and the LWG (2.6%, n = 888). Cesarean section rate was significantly higher in the HWG with 45.2% in comparison to 28.8% in the LWG with an odds ratio of 1.57 (95% CI 1.29-1.91, p<0.0001). In vaginal deliveries, a high birth weight was not associated with an increased risk of maternal birth injuries (LWG in vaginal deliveries: 74.3%, HWG in vaginal deliveries: 73.6%; p = 0.887; OR = 1.9 (95% CI 0.9-1.1)). CONCLUSION: A fetal weight above 3.79 kg does not predict increased maternal or infant morbidity after delivery from breech presentation at term. Neither the literature nor our analyses document evidence for threshold of estimated birth weight that is associated with maternal and/or infant morbidity. However, patients should be informed about an increased likelihood of cesarean sections during labor when attempting vaginal birth from breech position at term in order to reach an informed shared decision concerning the birth strategy. Further investigations in multi center settings are needed to advance international guidelines on vaginal breech deliveries in the context of estimated birth weight and its impact on perinatal outcome.
