Purpose of review This review summarizes recent progress in our understanding how environmental adjuvants promote the development of asthma. Recent findings Asthma is a heterogeneous set of lung pathologies with overlapping features. Human studies and animal models suggest that exposure to different environmental adjuvants activate distinct immune pathways, which in turn give rise to distinct forms, or endotypes, of allergic asthma. Depending on their concentrations, inhaled TLR ligands can activate either type 2 inflammation, or Th17 differentiation, along with regulatory responses that function to attenuate inflammation. By contrast, a different category of environmental adjuvants, proteases, activate distinct immune pathways and prime predominantly type 2 immune responses. Asthma is not a single disease, but rather a group of pathologies with overlapping features. Different endotypes of asthma likely arise from perturbations of distinct immunologic pathways during allergic sensitization.Background Limited data are available on the impact of a specialized extracorporeal membrane oxygenation (ECMO) team on clinical outcomes in patients with acute myocardial infarction (AMI) complicated by cardiogenic shock (CS). WNK-IN-11 mw This study evaluated whether specialized ECMO team is associated with improved in-hospital mortality in AMI patients undergoing veno-arterial (VA) ECMO. Methods A total of 255 AMI patients who underwent VA-ECMO were included. In January 2014, a multidisciplinary ECMO team was founded at our institution. Eligible patients were classified into a pre-ECMO team group (n = 131) and a post-ECMO team group (n = 124). The primary outcome was in-hospital mortality. Results In-hospital mortality (pre-ECMO team vs. post-ECMO team, 54.2% vs. 33.9%; p = 0.002) and cardiac intensive care unit mortality (pre-ECMO team vs. post-ECMO team, 51.9% vs. 30.6%; p = 0.001) were significantly lower after the implementation of a multidisciplinary ECMO team. On multivariable logistic regression model, implementation of the multidisciplinary ECMO team was associated with reduction of in-hospital mortality [odds ratio 0.37, 95% confidence interval (CI) 0.20-0.67; p = 0.001]. Incidence of all-cause mortality [58.3% vs. 35.2%; hazard ratio (HR) 0.49, 95% CI 0.34-0.72; p less then 0.001) and readmission due to heart failure (28.2% vs. 6.4%; HR 0.21, 95% CI 0.08-0.58; p = 0.003) at 6 months of follow-up were also significantly lower in the post-ECMO team group than in the pre-ECMO team group. Conclusions Implementation of a multidisciplinary ECMO team was associated with improved clinical outcomes in AMI patients complicated by CS. Our data support that a specialized ECMO team is indispensable for improving outcomes in patients with AMI complicated by CS.Transition is the structured crossing over of an adolescent patient from treatment by a pediatrician to that by an adult doctor. The transition falls in a difficult phase of life that includes the end of puberty, finding a job, obtaining training, gaining increasing autonomy, and "cutting off" from parents and the parents' home. In this article, problems with transition are explained with a focus on patients with chronic inflammatory bowel diseases. Structured transition programs are presented.There are different groups of patients who transfer to the adult care system adolescents with diseases that are well known (1) or unknown (2) in adult medicine and adolescents with disabilities who are treated in social pediatric centers (SPZ) (3). For the final group there are currently no adequate treatment structures in the adult care. Medical centers for adults with intellectual and multiple disabilities (MZEB) are currently being established. In all groups transition is understood as a dynamic process in which the patient, the parents, as well as the pediatric, adolescent and adult caregivers/physicians are involved. This generally runs over a long period of time and does not rely solely on a passive handover or transfer. Cancellation of therapy with subsequent problems is very common in this phase and sometimes very harmful for the affected patient. Structured cross-sector and cross-indication transition programs with case management elements, such as the Berlin Transition Program (BTP), offer support of patients in this phase of life and can prevent the consequences of inadequate adherence to therapy. The German Society for Pediatric and Adolescent Medicine (DGKJ), the German Society for Internal Medicine (DGIM), and the German Society for Neurology (DGN) have established a transition working group that supports the BTP.Background Fetal growth restriction often results from poor placental function and is a major cause of stillbirth. Clinically, fetal growth restriction is difficult to diagnose and currently has no effective treatment. Trophoblasts are unique placental cells that form the feto-maternal interface and facilitate nutrient and gas exchange. Fetal growth restriction is linked to inadequate trophoblast function. However, our understanding of the mechanisms underlying this dysfunction are poor, in part because of our inability to isolate and study the trophoblast stem cells from which mature trophoblasts arise in pathologic pregnancies. Methods Cells isolated from first-trimester placentae using the Hoechst side-population technique were propagated or differentiated into mature trophoblasts. Side-population trophoblasts were isolated from normal third-trimester and growth restricted placentae using the same technique. First and third-trimester side-population trophoblasts were compared by microarray analysis. Results First-trimester side-population trophoblasts could be propagated in an undifferentiated state or differentiated, via intermediate cytotrophoblasts, into syncytiotrophoblast or extravillous trophoblasts. Using the same technique, side-population trophoblasts could be isolated from term placentae for the first time, demonstrating that while they were present at consistent levels throughout gestation (~3·5%), side-population trophoblasts were significantly depleted in growth restricted pregnancies (0·32%). Conclusions Our novel method of isolating a population of human trophoblast stem cell-like cells directly from human placental tissue throughout gestation provides the first insights into trophoblast dysfunction in pregnancy pathologies. The depletion of side-population trophoblasts in growth restricted placentae may contribute to poor placental function.
