FLT3 mutations, which are found in a third of patients with acute myeloid leukemia (AML), are associated with poor prognosis. Responses to currently available FLT3 inhibitors in AML patients are typically transient and followed by disease recurrence. Thus, FLT3 inhibitors with new inhibitory mechanisms are needed to improve therapeutic outcomes. AMG925 is a novel, potent, small-molecule dual inhibitor of FLT3 and CDK4/6. In this study. we determined the antileukemic effects and mechanisms of action of AMG925 in AML cell lines and primary samples, in particular AML stem/progenitor cells. AMG925 inhibited cell growth and promoted apoptosis in AML cells with or without FLT3 mutations. Reverse-phase protein array profiling confirmed its on-target effects on FLT3-CDK4/6-regulated pathways and identified unrevealed signaling network alterations in AML blasts and stem/progenitor cells in response to AMG925. Mass cytometry identified pathways that may confer resistance to AMG925 in phenotypically defined AML stem/progenitor cells and demonstrated that combined blockade of FLT3-CDK4/6 and AKT/mTOR signaling facilitated stem cell death. Our findings provide a rationale for the mechanism-based inhibition of FLT3-CDK4/6 and for combinatorial approaches to improve the efficacy of FLT3 inhibition in both FLT3 wild-type and FLT3-mutated AML.

This study aims to test whether health workers experiencing both depression, anxiety and burnout would show severer burnout symptoms, and the potential moderating effect of anxiety and depression on mindfulness improving burnout.

This study was conducted in a comprehensive hospital of China in 2016. Debio 0123 A total of 924 healthcare professionals were included in this cross-sectional study with a response rate of 82.0%. Maslach Burnout Inventory, Patient Health Questionnaire-9, Generalized Anxiety Disorder, Perceived Stress Scale and Short Inventory of Mindfulness Capability were used to measure burnout, depression, anxiety, perceived stress and mindfulness. Univariate analysis, correlation analysis, mediation analysis and moderated mediation analysis were conducted.

Burnout and anxiety group (BA) and burnout and depression group (BD) reported significantly higher burnout scores compared to the burnout-only group (BO) (59.90 ± 15.700, 56.20 ± 13.190, and 49.99 ± 11.955, respectively). Perceived stress was a mediator between mindfulness and occupational burnout, and depression and anxiety significantly moderated the mediation path between mindfulness and occupational burnout (β for stress in moderated mediation models with depression and anxiety respectively β = 1.8088, p < 0.001, and β = 1.7908, p < 0.001). For participants who experienced a high level of depression, less occupational burnout was reduced as mindfulness increased. Indirect effect of mindfulness reducing occupational burnout was greater among participants who experienced less anxiety.

Depression and anxiety weakened the mindfulness ability on relieving occupational burnout, which could be the potential mechanism of the worsening effect of depression and anxiety.

This paper aims to build upon previous work to definitivelyestablish in vitro models of murinepseudoglandular stage lung development. These can be easily translated to human fetal lung samples to allow the investigation of lung development in physiologic and pathologic conditions.

Lungs were harvested from mouse embryos at E12.5 and cultured in three different settings, i.e., whole lung culture, mesenchyme-freeepithelium culture, and organoid culture. For the whole lung culture, extracted lungs were embedded in Matrigel and incubated on permeable filters. Separately, distal epithelial tips were isolated by firstlyremoving mesothelial and mesenchymal cells, and then severing the tips from the airway tubes. These were thencultured either in branch-promoting or self-renewing conditions.

Cultured whole lungs underwent branching morphogenesis similarly to native lungs. Real-time qPCR analysis demonstrated expression of key genes essential for lung bud formation. The culture condition for epithelial tips was optimized by testing different concentrations of FGF10 and CHIR99021 and evaluating branching formation. The epithelial rudiments in self-renewing conditions formed spherical 3D structures with homogeneous Sox9 expression.

We report efficient protocols for ex vivo culture systems of pseudoglandular stage mouse embryonic lungs. These models can be applied to human samples and could be useful topaediatric surgeons to investigate normal lung development, understand the pathogenesis of congenital lung diseases, and explore novel therapeutic strategies.

Gastroschisis is an index neonatal malformation with an increasing incidence from earlier decades. The aim of this study was to investigate regional variations in patient demographics, outcomes, and costs in gastroschisis.

The 2016 kid's inpatient database (KID) obtained from the Healthcare Cost and Utilization Project (HCUP) was used to obtain gastroschisis birth, demographic, and outcome data across four U.S. geographical regions Northeast, Midwest, South, and West. Categorical variables were analyzed with Pearson's Chi-squared test. Odds ratios (OR) with 95% confidence intervals (CI) were reported for variables with significance (p < 0.05). Appropriate logistic regressions were used for comparing categorical, cardinal, and continuous data.

2043 gastroschisis cases were obtained from the 2016 KID database with a weighted incidence of 5.1 per 10,000 live births. Incidence of gastroschisis across regions was similar when controlling for a number of hospitals reporting to KID. Prematurity was common, with 59% (1204) of neonates with gastroschisis born at less than 37weeks.
