We describe a Lean based Quality Improvement Project (QIP) to improve the defect rate of breast magnetic resonance imaging (MRI) studies by developing a MRI Technologist Breast Sub-specialization Program. Key stakeholders (physician and technologist) drove the QIP. Both the overall defect rate and the callback rate (severe defects requiring patients return for repeat imaging) were measured over a 2-month period as 17% and 6%, respectively. Lean visualization tools of Pareto Chart & Fishbone Diagram identified lack of multiple trends, but discerned that most defect causes were within the responsibility of the technologists...

Exercise promotes learning and memory formation. These effects depend on increases in hippocampal BDNF, a growth factor associated with cognitive improvement and the alleviation of depression symptoms. Identifying molecules that are produced during exercise and that mediate hippocampal Bdnf expression will allow us to harness the therapeutic potential of exercise. Here, we report that an endogenous molecule produced during exercise in male mice induces the Mus musculus Bdnf gene and promotes learning and memory formation...

The role of intravenous (IV) or nebulised magnesium sulphate (MgSO4 ) in the treatment of severe acute asthma in adults is unclear. A controversy exists regarding its efficacy. In children MgSO4 has a more evident clinical effect, but the child population has not been considered in this work. The applicability of the results from randomized clinical trials (RCTs) involving MgSO4 in adult population is questioned in the optimal treatment of asthma exacerbations. According to the newest guidelines from the Global Initiative for Asthma (GINA), optimal treatment in the emergency department (ED) is based on short-acting beta2 -agonists (SABA), oral or IV corticosteroids (CS), short acting muscarinic antagonists (SAMA) and the controlled oxygen therapy...

Chronic stress promotes depression in some individuals, but has no effect in others. Susceptible individuals exhibit social avoidance and anxious behavior and ultimately develop depression, whereas resilient individuals live normally. Exercise counteracts the effects of stress. Our objective was to examine whether lactate, a metabolite produced during exercise and known to reproduce specific brain exercise-related changes, promotes resilience to stress and acts as an antidepressant. To determine whether lactate promotes resilience to stress, male C57BL/6 mice experienced daily defeat by a CD-1 aggressor, for 10 days...

Deregulation of the RAS GTPase cycle due to mutations in the three RAS genes is commonly associated with cancer development. Protein tyrosine phosphatase SHP2 promotes RAF-to-MAPK signaling pathway and is an essential factor in RAS-driven oncogenesis. Despite the emergence of SHP2 inhibitors for the treatment of cancers harbouring mutant KRAS, the mechanism underlying SHP2 activation of KRAS signaling remains unclear. Here we report tyrosyl-phosphorylation of endogenous RAS and demonstrate that KRAS phosphorylation via Src on Tyr32 and Tyr64 alters the conformation of switch I and II regions, which stalls multiple steps of the GTPase cycle and impairs binding to effectors...

OBJECTIVE: Multiple sclerosis (MS) is an inflammatory and autoimmune disease associated with the imbalance of cytokines secreted from CD4+ T cells. Studies have shown that vitamin A and its active derivatives are able to modulate the immune system in MS patients. The aim of the present study was to investigate the effect of supplementation of retinyl palmitate (RP), the dietary form of vitamin A, on pro- and anti-inflammatory cytokines in the plasma and supernatants of cultured peripheral blood mononuclear cells (PBMCs) of MS patients...

MYC amplification is common in Group 3 medulloblastoma and is associated with poor survival. Group 3 and Group 4 medulloblastomas are also known to have elevated levels of histone H3-lysine 27-tri-methylation (H3K27me3), at least in part due to high expression of the H3K27 methyltransferase enhancer of zest homologue 2 (EZH2), which can be regulated by MYC. We therefore examined whether MYC expression is associated with elevated EZH2 and H3K27me3 in medulloblastoma, and if high-MYC medulloblastomas are particularly sensitive to pharmacological EZH2 blockade...

Background: European trials using procalcitonin (PCT)-guided antibiotic therapy for patients with lower respiratory tract infections (LRTIs) have demonstrated significant reductions in antibiotic use without increasing adverse outcomes. Few studies have examined PCT for LRTIs in the United States. Methods: In this study, we evaluated whether a PCT algorithm would reduce antibiotic exposure in patients with LRTI in a US hospital. We conducted a controlled pre-post trial comparing an intervention group of PCT-guided antibiotic therapy to a control group of usual care...

Kawasaki disease (KD) is an acute, systemic vasculitis and occurs mainly in childhood. Interleukin-6 (IL-6) is a pleiotropic cytokine synthesized predominantly by neutrophils and monocytes/macrophages and plays an important role in systemic inflammatory disease. However, a little information is currently available on the relationship of serum IL-6 with conventional inflammatory mediators, clinical classification, IVIG response and coronary artery aneurysm (CAA). 165 Chinese children with KD were enrolled and divided into six subgroups, including complete KD, incomplete KD, IVIG-responsive KD, IVIG-nonresponsive KD, coronary artery noninvolvement KD and coronary artery involvement KD...

Dysbiosis, or imbalance in the gut microbiome, has been implicated in auto-immune, inflammatory, neurological diseases as well as in cancers. More recently it has also been shown to be associated with ocular diseases. In the present study, the association of gut microbiome dysbiosis with bacterial Keratitis, an inflammatory eye disease which significantly contributes to corneal blindness, was investigated. Bacterial and fungal gut microbiomes were analysed using fecal samples of healthy controls (HC, n = 21) and bacterial Keratitis patients (BK, n = 19)...

BACKGROUND & AIMS: Vitamin A is considered as a supplement that effect on autoimmune diseases. We aimed to systematically review the effect of vitamin A on cytokines in patients with autoimmune disease. METHODS: Two researchers searched Scopus and PubMed until May 2018. Researchers extracted data from 6 eligible published papers. Extracted data included the gene expression of the inflammatory and anti-inflammatory cytokines. RESULTS: Fixed effect analysis of the WMD (95% CI) of the changes in gene expression showed that gene expression of the inflammatory (IL-17, IFN-γ and T-bet) and anti-inflammatory (TGF-β and FOXP3) cytokines significantly decreased and increased due to vitamin A supplementation in patients with autoimmune (Multiple sclerosis and atherosclerosis) diseases...
