Pain can be managed using various pharmacological and/or non-pharmacological strategies, which can be delivered by healthcare providers or parents. The aim of this study is to assess the attitude of mothers toward their children's pain and its management. A descriptive cross-sectional web-based study was conducted using a developed self-reported questionnaire, from March 2018 to April 2018. Participants involved were Arabic-speaking mothers of children aged between 0 and 12. The data collected included pharmacological and non-pharmacological treatment methodologies utilized to treat pain and the mothers' attitude towards pain management. Statistical Package for Social Sciences, version 25 was applied to analyze the data, and descriptive statistics were performed. As per the results of this study, the most common site of children's pain as reported by the mothers was mouth/throat (211; 52.9%), abdomen (199; 49.9%), followeenting educational and awareness programs about the management of child pain could play a major role in making the parents understand the impacts of their misconceptions.Circular RNAs (circRNAs) are a class of non-coding RNAs that form a covalently closed loop. A number of functions and mechanisms of action for circRNAs have been reported, including as miRNA sponge, exerting transcriptional and translational regulation, interacting with proteins, and coding for peptides. CircRNA dysregulation has also been implicated in many cancers, such as breast cancer. Their relatively high stability and presence in bodily fluids makes cancer-associated circRNAs promising candidates as a new biomarker. In this review, we summarize the research undertaken on circRNAs associated with breast cancer, discuss circRNAs as biomarkers, and present circRNA-based therapeutic approaches.Hypoxia is a key characteristic of tumor tissue.
