Sarcopenia is a prevalent and costly disease associated with serious negative health outcomes, and its prevalence will further grow as the percentage of elderly rises. Healthcare professionals play a crucial role in the prevention, identification and management of sarcopenia and in promoting the well-being of elders. Awareness and knowledge are the prerequisite and basis for these actions.The objective of the review was to summarize available publications to identify the healthcare professionals' awareness and knowledge about sarcopenia, and to identify knowledge gaps that interventions could address.The scoping review will be performed based on the Scoping Review guidelines published by JBI in Australia.Six electronic databases, including PubMed, Embase, CINAHL, Web of Science, Cochrane Library and CNKI were searched systematically. Two researchers independently screened the retrieved articles and extracted the information.A total of 6 studies were identified, including 5 quantitative studies and 1 qualitative study. These studies mainly were conducted in Australia, Netherlands and Brazil, and none from Asia. The awareness and knowledge of healthcare professionals about sarcopenia varied in different studies. With exception of one study conducted in oncology clinicians, other studies suggested that awareness and knowledge among healthcare professionals was incomplete and limited.The relatively few studies indicated that healthcare professionals had low awareness and limited knowledge of sarcopenia, which could influence and hinder the diagnosis and treatment of sarcopenia in practice. Future researches should develop a rigorously tested and valid sarcopenia knowledge assessment tool and researches conducted in larger samples are needed.

Long non-coding RNAs (lncRNAs) CRNDE has been identified as a tumor oncogene in glioma. However, its clinical significance and prognostic value in glioma have not been investigated until now. The aim of this study was to explore CRNDE expression levels and evaluated its clinical significance in glioma patients.Expression levels of lncRNA CRNDE in 164 glioma specimens were determined by quantitative real-time PCR (qRT-PCR). The chi-square test was used to explore CRNDE expression with respect to clinicopathological parameters. The overall survival was analyzed by log-rank test, and survival curves were plotted according to Kaplan-Meier. Univariate and multivariate analyses were performed to analyze the prognostic significance of CRNDE expression.Compared with nonneoplastic brain tissues, the expression level of CRNDE was significantly increased in glioma tissues (p0.01). CRNDE upregulation was correlated with larger tumor size (p = 0.011), higher WHO grade (p = 0.001), and recurrence (p = 0.008). Also, survival analysis proved that up-regulated CRNDE expression was associated with poor overall survival of glioma patients (p0.001). The multivariate Cox regression analysis indicated that CRNDE expression was an independent prognostic factor for overall survival.These results indicated that lncRNA CRNDE was associated with tumor progression and could be an independent prognostic factor for glioma patients.
