There is growing consensus that outpatient health services for young people (aged 12-25 years) need to deliver trauma-informed care to ameliorate the effects of trauma, offer safe treatments, and avoid retraumatization. Trauma-informed care has become a familiar term for many professionals; however, its operating definition lacks clarity. MEDLINE, Embase, and PsycINFO were systematically searched to clarify what trauma-informed care is, and what it should achieve in these settings. We reviewed 3,381 unique records, of which 13 met criteria for inclusion. Content analysis identified 10 components of trauma-informed care as it has been operationalized in practice seven of these occurred at the system-level (interagency collaboration; service provider training; safety; leadership, governance and agency processes; youth and family/carer choice in care; cultural and gender sensitivity; youth and family/carer participation), and three involved trauma-specific clinical practices (screening and assessment; psychoeducation; therapeutic interventions). There is a need for greater consensus regarding an operating definition of trauma-informed care and further research into outcomes for young people and their families/carers.Continuous glucose monitoring (CGM) has become a widely used tool in the ambulatory setting for monitoring glucose levels, as well as detecting uncontrolled hyperglycemia, hypoglycemia, and glycemic variability. The accuracy of some CGM systems has recently improved to the point of manufacture with factory calibration and Food and Drug Administration clearance for nonadjunctive use to dose insulin. In this commentary, we analyze the answers to six questions about what is needed to bring CGM into the hospital as a reliable, safe, and effective tool. The evidence to date indicates that CGM offers promise as an effective tool for monitoring hospitalized patients. During the current coronavirus disease 2019 crisis, we hope to provide guidance to healthcare professionals, who are seeking to reduce exposure to SARS-Cov-2, as well as preserve invaluable personal protective equipment. In this commentary, we address who, what, where, when, why, and how CGM can be adopted for inpatient use.Background - Pulmonary vein isolation (PVI) is an effective treatment strategy for patients with atrial fibrillation (AF), but many experience AF recurrence and require repeat ablation procedures. The goal of this study was to develop and evaluate a methodology which combines machine learning (ML) and personalized computational modeling to predict, prior to PVI, which patients are most likely to experience AF recurrence after PVI. Methods - This single-center retrospective proof-of-concept study included 32 patients with documented paroxysmal AF who underwent PVI and had pre-procedural late gadolinium enhanced magnetic resonance imaging (LGE-MRI). For each patient, a personalized computational model of the left atrium simulated AF induction via rapid pacing. Features were derived from pre-PVI LGE-MRI images and from results of simulations (SimAF). The most predictive features were used as input to a quadratic discriminant analysis ML classifier, which was trained, optimized, and evaluated with 10-fold nested cross validation to predict the probability of AF recurrence post-PVI. Results - In our cohort, the ML classifier predicted probability of AF recurrence with an average validation sensitivity and specificity of 82% and 89%, respectively, and a validation AUC of 0.82. Dissecting the relative contributions of SimAF and raw images to the predictive capability of the ML classifier, we found that when only features from SimAF were used to train the ML classifier, its performance remained similar (validation AUC=0.81). However, when only features extracted from raw images were used for training, the validation AUC significantly decreased (0.47). Conclusions - ML and personalized computational modeling can be used together to accurately predict, using only pre-PVI LGE-MRI scans as input, whether a patient is likely to experience AF recurrence following PVI, even when the patient cohort is small.Background - Mutations in the gene encoding the sodium channel Nav1.5 cause various cardiac arrhythmias. This variety may arise from different determinants of Nav1.5 expression between cardiomyocyte domains. At the lateral membrane and T-tubules, Nav1.5 localization and function remain insufficiently characterized. Methods - We used novel single-molecule localization microscopy (SMLM) and computational modeling to define nanoscale features of Nav1.5 localization and distribution at the lateral membrane (LM), the LM groove, and T-tubules (TT) in cardiomyocytes from wild-type (N = 3), dystrophin-deficient (mdx; N = 3) mice, and mice expressing C-terminally truncated Nav1.5 (ΔSIV; N = 3). We moreover assessed TT sodium current by recording whole-cell sodium currents in control (N = 5) and detubulated (N = 5) wild-type cardiomyocytes. Results - We show that Nav1.5 organizes as distinct clusters in the groove and T-tubules which density, distribution, and organization partially depend on SIV and dystrophin. We found that overall reduction in Nav1.5 expression in mdx and ΔSIV cells results in a non-uniform re-distribution with Nav1.5 being specifically reduced at the groove of ΔSIV and increased in T-tubules of mdx cardiomyocytes. A TT sodium current could however not be demonstrated. Conclusions - Nav1.5 mutations may site-specifically affect Nav1.5 localization and distribution at the lateral membrane and T-tubules, depending on site-specific interacting proteins. selleck kinase inhibitor Future research efforts should elucidate the functional consequences of this redistribution.This work expanded the knowledge of the molecular mechanisms underlying LC progression by exploring the role of miR-892a in the viability of TU212 and M4E cells. The results showed that miR-892a, which exhibited elevated expression in LC cells and tissue specimens of patients with LC, exerted an inhibitory effect on Dicer expression, whereas silencing of miR-892a in TU212 and M4E cells hindered cell proliferation and growth and promoted apoptosis. Furthermore, miR-892a was demonstrated to directly target Dicer 3'-UTR and inhibit its expression. These findings demonstrated that miR-892a acted as an LC oncogene via its action on Dicer, which further confirmed that miR-892a can serve as a diagnostic indicator or promising agent for LC treatment.
