Correlation between different CMR criteria varied from moderate to very strong. In multivariate binary logistic regression analysis with CMR and non-CMR parameters, independent positive predictors for a (L)PV were familial cardiomyopathy, trabecular mass, and meeting Petersen criteria in ≥2 out of 3 long axis views, while left bundle branch block and hypertension were negative predictors. The ROC-curve of this multivariate model had an area under the curve of 0.89 (95%CI 0.82-0.97). Conclusion CMR criteria together with family history help to distinguish those patients in whom a (L)PV can be identified, consequently leading to referral for genetic diagnostics and cascade screening.Objective This study aimed to identify outcome determinants for extracorporeal membrane oxygenation (ECMO) as a bridge to lung transplantation (BTT) at our institution. Methods This retrospective single-center study reviewed patients on ECMO between 2010 and 2018 and compared clinical characteristics between patients who underwent successful-BTT and those who did not. Additionally, we examined differences between actively vs. emergently listed patients and reasons for failure-to-list. Results 76 patients were placed on ECMO with the intent to bridge to transplant. Of those, 42 were actively on the waitlist (AWL) prior to ECMO initiation, 20 were emergently evaluated and waitlisted (EWL) after ECMO initiation, and 14 failed-to-list. Of the 62 listed patients, 42 (68%) were successfully transplanted. Risk factors of failed-BTT included RV dysfunction prior to ECMO initiation, longer ECMO duration, reduced mobility status, shorter stature, higher prevalence of blood type B, worse kidney and liver function, and increased transfusion requirements. The number of patients transitioned to central VA-ECMO was higher in the failed-BTT group. Thirty-day survival post-transplantation was 98%, with 90% successfully discharged; 1-year survival conditional upon discharge was 97%. AWL and EWL groups had comparable outcomes. Reasons for failure-to-list are not readily modifiable. Conclusions ECMO-BTT has become a viable option with satisfactory 1-year survival in patients with irreversible lung injury. Our results support rescue transplant for emergently evaluated and waitlisted patients on ECMO. Our data suggests that modification in national organ allocation policies especially as they pertain to high-acuity recipients with rare blood types and short stature could enhance successful outcome.Schizophrenia patients are at higher risk of engaging in violent behavior than the general population. Schizophrenia is also regarded as a highly heritable disorder. This study aims to analyze genome-wide the effect of SNPs on violence in schizophrenia. We recruited 205 subjects between the age of 18-75 from the Centre for Addiction and Mental Health (CAMH), who had a diagnosis of schizophrenia or schizoaffective disorder. We recorded physical, verbal and lifetime violence scores indicating any violent actions to inflict pain, bodily harm, or death on another individual from the standardized scale, Modified Overt Aggression Scale (MOAS). We genotyped each participant DNA using the Illumina Omni 2.5, and the SNPs were analyzed using the whole genome analysis tool-set, PLINK. We probed for single nucleotide polymorphisms (SNPs) correlated with violence in schizophrenia patients. We found one SNP (rs2188177) on chromosome 7 which showed a trend for association with physical violence (p = 7.80E-06). This study is the first of its kind to investigate genome-wide, the polymorphisms associated with violence in schizophrenia. The findings of this study may promote collaborative efforts to understand the genetic basis of violent behavior in psychosis.In this paper we explore the phenomenon of pleiotropy in neurodegenerative diseases, focusing on Alzheimer's disease (AD). We summarize the various techniques developed to investigate pleiotropy among traits, elaborating in the polygenic risk scores (PRS) analysis. PRS was designed to assess a cumulative effect of a large number of SNPs for association with a disease and, later for disease risk prediction. Since genetic predictions rely on heritability, we discuss SNP-based heritability from genome-wide association studies and its contribution to the prediction accuracy of PRS. We review work examining pleiotropy in neurodegenerative diseases and related phenotypes and biomarkers. Selleck XMU-MP-1 We conclude that the exploitation of pleiotropy may aid in the identification of novel genes and provide further insights in the disease mechanisms, and along with PRS analysis, may be advantageous for precision medicine.Dravet syndrome is a severe infantile-onset epileptic encephalopathy which begins with febrile seizures and is caused by heterozygous loss-of-function mutations of the voltage-gated sodium channel gene SCN1A. We designed a CRISPR-based gene therapy for Scn1a-haplodeficient mice using multiple guide RNAs (gRNAs) in the promoter regions together with the nuclease-deficient Cas9 fused to transcription activators (dCas9-VPR) to trigger the transcription of SCN1A or Scn1a in vitro. We tested the effect of this strategy in vivo using an adeno-associated virus (AAV) mediated system targeting inhibitory neurons and investigating febrile seizures and behavioral parameters. In both the human and mouse genes multiple guide RNAs (gRNAs) in the upstream, rather than downstream, promoter region showed high and synergistic activities to increase the transcription of SCN1A or Scn1a in cultured cells. Intravenous injections of AAV particles containing the optimal combination of 4 gRNAs into transgenic mice with Scn1a-haplodeficiency and inhibitory neuron-specific expression of dCas9-VPR at four weeks of age increased Nav1.1 expression in parvalbumin-positive GABAergic neurons, ameliorated their febrile seizures and improved their behavioral impairments. Although the usage of transgenic mice and rather modest improvements in seizures and abnormal behaviors hamper direct clinical application, our results indicate that the upregulation of Scn1a expression in the inhibitory neurons can significantly improve the phenotypes, even when applied after the juvenile stages. Our findings also suggest that the decrease in Nav1.1 is directly involved in the symptoms seen in adults with Dravet syndrome and open a way to improve this condition.Selleck XMU-MP-1
