AKT-mTORC1 (mammalian target of rapamycin complex 1) signaling pathway plays a critical role in tumorigenesis and can be targeted by rapamycin. However, the underlying mechanism of how long noncoding RNA (lncRNAs) regulate the AKT-mTORC1 pathway remains unclear. EPIC1 (epigenetically-induced lncRNA 1) is a Myc-binding lncRNA, which has been previously demonstrated to be overexpressed in multiple cancer types. In a pathway analysis including 4962 cancer patients, we observed that lncRNA EPIC1 expression was positively correlated with the AKT-mTORC1 signaling pathway in more than 10 cancer types, including breast and ovarian cancers. RNA-seq analysis of breast and ovarian cancer cells demonstrated that EPIC1-knockdown led to the downregulation of genes in the AKT-mTORC1 signaling pathway. In MCF-7, OVCAR4, and A2780cis cell lines, EPIC1 knockdown and overexpression, respectively, inhibited and activated phosphorylated AKT and the downstream phosphorylation levels of 4EBP1 and S6K. Further knockdown of Myc abolished the EPIC1's regulation of AKT-mTORC1 signaling; suggested that the regulation of phosphorylation level of AKT, 4EBP1, and S6K by EPIC1 depended on the expression of Myc. Moreover, EPIC1 overexpressed MCF-7, A2780cis, and OVCAR4 cells treated with rapamycin showed a significant decreasing in rapamycin mediated inhibition of p-S6K and p-S6 comparing with the control group. In addition, Colony Formation assay and MTT assay indicated that EPIC1 overexpression led to rapamycin resistance in breast and ovarian cancer cell lines. Our results demonstrated the lncRNA EPIC1 expression activated the AKT-mTORC1 signaling pathway through Myc and led to rapamycin resistance in breast and ovarian cancer.
To assess computerised tomography (CT) use and the risk of intracranial haemorrhage (ICH) in children with bleeding disorders following a head trauma.

Design Multicentre prospective observational study.

10 paediatric emergency departments (ED) in Australia and New Zealand.

Children <18 years with and without bleeding disorders assessed in ED following head trauma between April 2011 and November 2014.

Data collection of patient characteristics, management and outcomes.

Rate of CT use and frequency of ICH on CT.

Of 20 137 patients overall, 103 (0.5%) had a congenital or acquired bleeding disorder. CT use was higher in these patients compared with children without bleeding disorders (30.1 vs. 10.4%; rate ratio 2.91 95% CI 2.16-3.91). Only one of 31 (3.2%) children who underwent CT in the ED had an ICH. This patient rapidly deteriorated in the ED on arrival and required neurosurgery. None of the patients with bleeding disorders who did not have a CT obtained in the ED or had an initial negative CT had evidence of ICH on follow up.

Although children with a bleeding disorder and a head trauma more often received a CT scan in the ED, their risk of ICH seemed low and appeared associated with post-traumatic clinical findings. Selective CT use combined with observation may be cautiously considered in these children based on clinical presentation and severity of bleeding disorder.

We evaluated the efficacy of an innovative model to eliminate HCV infection in a high-risk population of PWUD in a service for substance use disorder (SUD). Between January 2018 and December 2018, we conducted a prospective, interventional, before and after study, based on audits performed by Infectious Diseases physicians in a SUD facility in Piedimonte Matese, in southern Italy, to improve the knowledge about HCV infection; a shared protocol for screening and linkage to care of patients was implemented. The pre-intervention period was defined as January-December 2017 and the post-intervention period as January-December 2018. The subjects followed up at SUD facility in the pre-intervention and post-intervention periods were 318 and 275, respectively. learn more Compared with the pre-intervention period, the number of anti-HCV-positive subjects tested for HCV RNA was higher in the post-intervention period (91% vs 27%, P less then .0001), as was the number who started directly acting antivirals (DAAs). Of the 18 HCV RNA-positive subjects in the pre-intervention period, only 3 (16.6%) started DAA, a percentage decisively lower than that observed after the start of the programme, 63 (84%) of 75 subjects (P less then .0001), and all obtained SVR. The data were similar for people who inject drugs (PWID) and non-PWID sub-populations. The use of our innovative model with close interaction between the Infectious Disease Unit and the SUD facility determined a significant increase in HCV RNA testing, linkage to care and the start of DAA in the PWUD population.The pathogenesis of ulcerative colitis (UC) is to be further investigated. House dust mites (HDM) are highly associated with the pathogenesis of immune inflammation in the body. This study aims to investigate the role of enolase (one of the HDM-derived proteins)-specific cross Abs in the induction of UC-like inflammation. The enolase specific IgG (EsIgG) was identified in UC patients by mass spectrometry. Mice were treated with EsIgG to induce inflammation in the colon mucosa. EsIgG was detected in the serum and the colon tissues of UC patients, which was positively correlated with the polymorphonuclear neutrophil (PMN) counts in the blood and colon tissues of UC patients. EsIgG formed immune complexes with the constitutive enolase in the UC colon epithelium that activated complement, induced epithelial cell apoptosis, compromised epithelial barrier functions, and resulted in UC-like inflammation in the mouse colon. In summary, UC patients have high serum levels of Abs against HDM-derived enolase and intestinal epithelial cell-derived enolase.
