(1) Background: While the association between nurse mental health and quality and safety of patient care delivery was well documented pre-pandemic, fewer research studies have examined this relationship in the context of COVID-19. This study examines the impact of various mental health symptoms experienced by nurses on quality and safety before and during the COVID-19 pandemic; (2) Methods: A secondary analysis of cross-sectional survey data from 4729 and 3585 nurses in one Canadian province between December 2019 and June-July 2020 was conducted. Data were analyzed using between group difference tests and logistic regression; (3) Results: Compared to pre-COVID-19, during COVID-19 nurses reported a higher safety grade, a greater likelihood of recommending their units for care and lower quality of nursing care. Most mental health symptoms were higher during COVID-19 and higher levels of mental health symptoms were correlated with lower ratings of quality and safety both pre- and during COVID-19; (4) Conclusion: Mental health symptoms have implications for nurses’ quality and safety of patient care delivery, with the association between mental health symptoms and quality and safety following a dose–response relationship before and during COVID-19. These findings suggest that it is worthwhile for nurse mental health symptoms to be included as hospital level performance metrics.

In this rapidly developing new media era, a variety of social media is popping up. This paper takes Xiaohongshu as a case study to investigate the correlation between Xiaohongshu development and female users as well as analyse its impact on female construction. Based on data evaluation and literature research, the paper discusses the historical origin, development process and current situation of Xiaohongshu. According to the results, as one of the most popular apps in China, the success of Xiaohongshu is closely related to women, which also promotes women's construction. It also confirms that the success of a media or a platform is based on the user's grasp. These results shed light on how social media affected gender construction.
