Here, we are committed to explore the diagnostic and prognostic value of serum exosomal XIST secreted by tumour cells to predict recurrence in patients with triple-negative breast cancer (TNBC). Significant increments in XIST and exo-XIST from tumour tissues and blood serum were found in reoccurring TNBC patients by comparison with non-recurrences. Levels of serum exo-XIST were only significantly increased in TNBC recurrence and no association with other clinicopathological parameters. Additionally, serum exo-XIST levels could be served as an assessment of change in the load of triple-negative breast cancer. Expressions of exo-XIST were markedly decreased after resection of the primary breast tumours and obviously elevated at the time of recurrence. Finally, an obvious association was identified between serum exo-XIST levels and a poorer overall survival (OS) in TNBC patients. Levels of serum exo-XIST may serve as a diagnostic and prognostic biomarker to predict the recurrent TNBC-loading status.Nursing and nurses have become reliant on qualitative methods to understand the meaning of nursing care, and many nurse researchers use Heideggerian Interpretivist phenomenology approaches. Often these nurses are unaware of Martin Heidegger's role in the German National Socialist Party of the 1930s and his allegiance to fascist ideology. We ask can a bad person have good ideas? In line with pragmatic thinkers such as Richard Rorty, we argue that instead of value judgements on people and their ideas, nurses should consider ideas as a product of a historical/social and political time and space. In urging a critical political engagement, we argue for a Husserlian approach. In opposition to Heidegger's interpretivist phenomenology approach, in which the hegemony of the day is integral to the phenomena bei
