Nurses often face a variety of work-related and life-related stresses that make them more prone to symptoms of post-traumatic stress disorder (PTSD), yet the underlying mechanism of this association is poorly understood. To address this research gap, we investigated the mediating role of maladaptive cognitive emotion regulation strategies in the relationship between perceived stress and PTSD symptoms, and explored whether psychological capital could moderate the direct or indirect effects between perceived stress and PTSD symptoms. Nurses (N = 723) completed a questionnaire about perceived stress, PTSD symptoms, maladaptive cognitive emotion regulation strategies and psychological capital. After controlling for gender, age and work department, perceived stress was positively correlated with PTSD symptoms. Maladaptive cognitive emotion regulation strategies partially mediated this relationship. Psychological capital moderates the effects of perceived stress and maladaptive cognitive emotion regulation strategies on PTSD symptoms. Specifically, the positive correlation between perceived stress and PTSD symptoms was stronger among nurses with low levels of psychological capital than among nurses with high levels of psychological capital. At the same time, the positive correlation between maladaptive cognitive emotion regulation strategies and PTSD symptoms was stronger in nurses with a low level of psychological capital. Therefore, cognitive strategies and interventions oriented toward psychological capital may alleviate the PTSD symptoms of nurses in stressful situations.

BackgroundStatistics indicate that the morbidity of breast cancer is increasing globally, and its (overall figures) incidence has now surpassed that of lung cancer for the first time. The relation between a whole dietary pattern, rather than of a single food or nutrient, and breast cancer (BC) should be examined for findings to capture the complexities of diet and the potential for synergism between dietary components. Hence, the effects of dietary patterns on breast cancer have recently attracted increasing attention.ObjectiveTo systematically review the effects of dietary patterns on breast cancer risk, prognosis, and quality of life in survivors.MethodsThis systematic review was conducted following PRISMA guidelines and was registered in PROSPERO. Data from Ovid, China Biomedical Literature Database, Wanfang Data Knowledge Service Platform, CNKI, PubMed, Weipu, The Cochrane Library, Duxiu Data, ProQuest, Embase, Web of Science, and Scopus Database were retrieved and evaluated.ResultsA total of 47 studies that investigated the association between eating patterns and breast cancer were identified. Ten studies evaluated the effect of the model on treatment outcome and prognosis of breast cancer and two cross-sectional studies examined the influence of dietary patterns on quality of life. The resulting favorable dietary patterns were shown to regulate metabolic biomarkers, antioxidants, anti-inflammatory agents, and protective genes, and inhibit cell proliferation and invasion.ConclusionNumerous studies have examined the effects of healthy eating, plant-based, anti-inflammation, low-fat, and other favorable dietary patterns in relation to breast cancer. However, few studies reported significant associations and the studies had limitations, suggesting that the current findings should be interpreted with caution.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/, CRD4202 2350171.

Aims To investigate the association between professionalism and social media competence among Chinese mainland nursing undergraduates. Design This study employed a cross‐sectional descriptive correlation design. Participants From June to July 2021, 797 nursing students from four nursing colleges in Jiangsu Province, China, were chosen using stratified cluster sampling. Methods The questionnaire included the Chinese version of the Nursing Professionalism Scale and the Social Media Competency Scale. The association between professionalism and social media competency was examined using Pearson's correlation analysis. Results The professionalism of nursing undergraduates (average scores:70.44 ± 8.82) was at a medium level. Social media self‐efficacy, performance expectancy, facilitating conditions and social influence (3.76 ± 0.75, 3.87 ± 0.60, 3.53 ± 0.69, 3.41 ± 0.76) were at a medium–high level, while social media experience and effort expectancy (3.03 ± 0.72, 2.60 ± 0.59) were at medium and low levels. Among nursing undergraduates, professionalism was related to social media competence, among which, professionalism was positively correlated with social media self‐efficacy (r = 0.40, p < 0.01), social media experience (r = 0.50, p < 0.01), performance expectancy (r = 0.34, p < 0.01), facilitating conditions (r = 0.41, p < 0.01), but negatively correlated with effort expectancy (r = −0.10, p < 0.01). Conclusion The professionalism of nursing undergraduates is related to social media. The scores of social media self‐efficacy, social media experience, performance expectancy and facilitating conditions of nursing students with high professionalism were higher than those of nursing students with low professionalism. Impact This study suggests that developing a course on health communication on social media can help nursing students improve their professionalism. Patient or Public Contribution Participants completed a survey via the online survey platform Wenjuangxing.

Nurses often face a variety of nursing-related stresses, making them more prone to symptoms of posttraumatic stress disorder (PTSD). We aimed to explore symptom characteristics, influencing factors, and their predictive value for PTSD in nurses, so as to prevent the occurrence of PTSD in nurses. This was a cross-sectional study conducted in two tertiary hospitals in Yangzhou. A total of 1290 valid questionnaires were received in our study, and 190 nurses (14.7%) were positive for PTSD symptoms. The results show that individuals with higher scores on the Perceived Stress Scale-10 (PSS-10), Patient Health Questionnaire-15 (PHQ-15), Generalized Anxiety Disorder Scale-7 (GAD-7), and maladaptive cognitive emotion regulation strategies questionnaire (maladaptive CERS) were more likely to experience PTSD symptoms, whereas those with lower scores on the Perceived Social Support Scale (PSSS) were more likely to experience PTSD symptoms. Compared with the PSS-10, PHQ-15, and PSSS, GAD-7 and maladaptive CERS had higher predictive value. This study provided the optimal threshold of relevant factors that may have a positive effect on the prevention of PTSD symptoms. This has guiding implications for active prevention and intervention in some institutions.
