Fatigue as a Cause of Professional Dissatisfaction Among Chinese Nurses in Intensive Care Unit During COVID-19 Pandemic.

Aim: To clarify the mediating role of burnout and the moderating role of turnover intention in the association between fatigue and job satisfaction among Chinese nurses in intensive care units (ICU) during the COVID-19 pandemic. Methods: A cross-sectional survey of fifteen provinces in China was conducted, using an online questionnaire, from December 2020 to January 2021, during the COVID-19 pandemic. A total of 374 ICU nurses (effective response rate: 71.37%) provided sufficient responses. Sociodemographic factors, job demographic factors, fatigue, burnout, job satisfaction, and turnover intention were assessed using questionnaires. General linear modeling (GLM), hierarchical linear regression (HLR) analysis, and generalized additive modeling (GAM) were performed to examine all the considered research hypotheses. Results: Fatigue was found to be negatively and significantly associated with job satisfaction. Moreover, burnout played a partial mediating role and turnover intention played a moderating role in the relationship between fatigue and job satisfaction. Conclusion: Over time, a state of physical and mental exhaustion and work weariness among Chinese ICU nurses potentially results in job burnout and consequently promotes the level of job dissatisfaction. The results also found that turnover intention played a moderating role in the relationship between burnout and job satisfaction. Specific policies could be considered to eliminate nurses' fatigue and negative attitudes during times of public health emergencies.

Current Status of Intergroup Threats Perceived by Chinese Physicians and Its Association with Organizational Psychology, Behavior, and Well-Being during the COVID-19 Pandemic: A Cross-Sectional Survey.

(1) Background: Chinese physicians have encountered serious physical and verbal attacks in recent decades due to poor patient−physician relationships, leading to a broad spectrum of negative consequences. This study aims to assess the status of intergroup threats perceived by physicians and explore its association with organizational psychology, behavior, and well-being during the COVID-19 pandemic. (2) Methods: We conducted a cross-sectional online survey with physicians from November to December 2020 in three provinces: Heilongjiang Province, Henan Province, and Zhejiang Province, in China. A total of 604 physicians were recruited to complete an anonymous questionnaire. There were 423 valid questionnaires. (3) Results: We developed a 25-item intergroup threat scale with four dimensions: interest damage, performance impairment, value derogation, and unjust sentiment. Internal consistency reliability analyses showed that the four dimensions and overall scale exhibited high internal consistency (0.756−0.947). Additionally, the average scores for physicians' perceived overall intergroup threat, interest damage, performance impairment, value derogation, and unjust sentiment were 4.35 ± 0.51, 4.24 ± 0.73, 4.33 ± 0.58, 4.22 ± 0.65, and 4.53 ± 0.55, respectively. Moreover, this study shows that the intergroup threats perceived positively by physicians were associated with psychological stress (ß = 0.270, p < 0.01), emotional exhaustion (ß = 0.351, p < 0.01), turnover intention (ß = 0.268, p < 0.01), and defensive medical behavior (ß = 0.224, p < 0.01), and were negatively associated with job satisfaction (ß = −0.194, p < 0.01) and subjective well-being (ß = −0.245, p < 0.01). (4) Conclusions: The newly developed scale in this study is a reliable tool for measuring intergroup threats perceived by Chinese physicians. Physicians in China were suffering high-level intergroup threats during the anti-COVID-19 pandemic, which has a significant impact on damage to organizational psychology, behavior, and well-being. Intergroup threats perceived by physicians not only enlarged the risk of emotional exhaustion and psychological stress but also threatened organizational well-being. Moreover, greater intergroup threats were associated with a lower job satisfaction, more frequent defensive medical behavior, and a higher turnover intention for physicians. The results of this study suggest that essential intervention and governance measures should be considered to protect physicians' well-being and benefits in China, which are urgently needed.

Can resilience promote calling among Chinese nurses in intensive care units during the COVID-19 pandemic? The mediating role of thriving at work and moderating role of ethical leadership.

Background: Nurses working in the intensive care unit (ICU) clung tenaciously to their job during the COVID-19 pandemic in spite of enduring stressed psychological and physical effects as a result of providing nursing care for the infected patients, which indicates that they possessed a high degree of professionalism and career calling. The aim of this study was to explain the associations between resilience, thriving at work, and ethical leadership influencing the calling of ICU nurses. Methods: From December 2020 to January 2021 during the COVID-19 pandemic, a cross-sectional survey of 15 provinces in China was conducted using an online questionnaire. A total of 340 ICU nurses (effective response rate: 64.89%) completed sufficient responses to be used in the study. Sociodemographic factors, job demographic factors, resilience, calling, thriving at work, and ethical leadership were assessed using the questionnaire. General linear modeling (GLM), hierarchical linear regression (HLR) analysis, and generalized additive model (GAM) were performed to examine all the considered research hypotheses. Results: Resilience was positively and significantly associated with calling. Moreover, thriving at work partially mediated the relationship between resilience and calling. The indirect effect of resilience on calling was 0.204 (p < 0.0001), and the direct effect of resilience on calling through thriving at work was 0.215 (p < 0.0001). The total effect of resilience on calling was 0.419 (p < 0.0001). In addition, ethical leadership played a moderating role in the relationship between resilience and calling (ß = 0.16, p < 0.05). Conclusion: Greater resilience can positively predict increased calling among Chinese ICU nurses during the COVID-19 pandemic. Moreover, thriving at work is a mechanism that partly transmits the positive effects of resilience on calling. Overall, nurses possessing greater resilience tend to maintain thriving at work in the face of such adversity, further resulting in subsequently increased calling. Besides, findings suggest that there is stronger influence of resilience on calling among nurses working in an organization managed by an ethical leader. The current findings may offer two insights for nursing practitioners and policymakers in the postpandemic world. First, resilience training and intervention are necessary to foster nurses' sense of thriving at work in the nursing industry, further promoting career calling. Second, better training and effort on the development of ethical leadership for leaders in nursing practice are essential to encourage followers to engage in social learning of ethical behaviors and abiding by normatively appropriate conduct, further enacting prosocial values and expressing moral emotions.

Association Between Self-Perceived Stigma and Quality of Life Among Urban Chinese Older Adults: The Moderating Role of Attitude Toward Own Aging and Traditionality.

BACKGROUND: Ageism is a global challenge, which leads to a range of adverse outcomes for elderly people worldwide, which maybe more severe among urban older adults in a competitive society. However, how self-perceived ageism influences the quality of life in a sample of urban older adults remains inconclusive. OBJECTIVES: The current study aims to assess the status of self-perceived stigma among urban Chinese older adults, identify its relationship with quality of life, and further explore whether both attitude toward own aging and traditionality moderate this relationship. MATERIALS AND METHODS: Primary data were collected through cross-sectional surveys among urban older adults in three provinces of China from October 2019 to December 2020. A total of 764 urban older adults were valid participants (effective response rate = 81.28%) and completed questionnaires via anonymous face-to-face interviews. Socio-demographic factors, self-perceived stigma, attitude toward own aging, traditionality, and quality of life were assessed using questionnaires that included the Self-perceived Stigma, Attitude Toward Own Aging, Traditionality, and SF-8 Scales. RESULTS: For urban Chinese older adults, the average score of self-perceived stigma was 2.041 ± 0.726. Self-perceived stigma (ß = -0.391, p < 0.05) and attitude toward own aging (ß = -0.211, p < 0.05) both influenced quality of life. Additionally, attitude toward own aging (ß = -0.530, p < 0.05) and traditionality (ß = -0.525, p < 0.05) moderated the association between self-perceived stigma and quality of life. Simple slope analysis revealed that when the level of negative attitude toward own aging and traditionality was higher, the strength of the influence of self-perceived stigma on quality of life was stronger. CONCLUSION: Urban Chinese older adults were aware of the self-perceived stigma, which contributes to decreased quality of life. Attitude toward own aging and traditionality could moderate the association between self-perceived stigma and quality of life. When negative attitudes toward own aging and traditionality are higher, self-perceived stigma has a greater effect on the quality of life. More interventions related to relieving self-perceived stigma, traditionality, and negative attitude toward own aging should be considered to build a new modern society that emphasizes health, friendliness, well-being, and dignity for all ages.

Characteristics of Agraphia in Chinese Patients with Alzheimer's Disease and Amnestic Mild Cognitive Impairment.

BACKGROUND: Patients with Alzheimer's disease (AD) manifest progressive decline in writing abilities. Most studies on agraphia in AD have been performed in the alphabetic system, such as English. However, these findings may not be applicable to other written language systems. The unique features of the Chinese written script could affect the patterns of agraphia in Chinese AD patients. The aim of this study was to explore the features of writing errors in Chinese patients with AD and amnestic mild cognitive impairment (a-MCI), as well as to study the relationship between their writing errors and neuropsychological functions. METHODS: In this study, we performed an observational study in a group of subjects including 17 AD patients, 14 patients with a-MCI, and 16 elderly healthy controls. We analyzed the writing errors in these subjects and also studied the relationship between their writing errors and neuropsychological functions. RESULTS: Our study showed that in patients whose mother tongue is Chinese, writing ability was comparatively well preserved in the MCI phase but significantly impaired when the disease progressed to the stage of AD. The writing errors showed corresponding increase with the severity of cognition decline, both in the types of errors and rate of occurrence. Analysis of the writing errors showed that word substitution and unintelligible words were the most frequent error types that occurred in all the three study groups. The occurrence rate of unintelligible words was significantly higher in the AD group compared with the a-MCI group (P = 0.024) and control group (P = 0.018). In addition, the occurrence rates of word substitution were also significantly higher in AD (P = 0.013) and a-MCI groups (P = 0.037) than that of control group. However, errors such as totally no response, visuospatial impairment, paragraph agraphia, ideograph, and perseverative writing errors were only seen in AD group. Besides, we also found a high occurrence rate of visuoconstructional errors (13.3%) in our AD group. CONCLUSIONS: Our study confirmed that agraphia is an important feature in patients with AD. The writing error profile in patients whose native language is Chinese was unique compared to patients using the alphabetic language system.

[The adolescent physical exercise behavior-psychological measurement scale on the Chinese version and its reliability and validity study].

OBJECTIVE: To develop a suitable physical exercise behavior-psychological scale for the Chinese adolescents and to evaluate its validity and reliability. METHODS: A total of 3600 junior students were recruited and tested through multistage sampling method. Reliability was assessed, using Cronbach's α and split-half reliability; while exploratory factor analysis and confirmatory factor analysis were used to test its validity, with entries-dimension correlation coefficient (IIC), correlation coefficient between the scores and the dimension, the dimension of correlation coefficient test content validity. RESULTS: The internal consistency reliabilities for total scale score (Cronbach's α = 0.888), Cronbach's α of four domains were 0.880, 0.706, 0.552 and 0.839, respectively. The four-domain split-efficacy reliabilities were ranged between 0.559 and 0.876. Data from the exploratory factor analysis revealed the following dimensions: the entries were all inclusive; the cumulative contribution rate was more than 40%. RESULTS: from the confirmatory factor analysis showed that the absolute fit measures of GFI = 0.972, AGFI = 0.958, RMSEA = 0.032 (90%CI: 0.030 - 0.034) could satisfy the condition while the model fit was better. The results of IIC showed: in the four dimensions, and the contained entries between Spearman correlation coefficient range were 0.396 - 0.700, 0.470 - 0.709, 0.696 - 0.771 and 0.665 - 0.813, while other dimensions from weak to moderate relationships, the r value range was from 0.386 to 0.935. With the change of the phase changing process, decision balance, self-efficacy scores were differently prompting the health-related intervention periodically and pertinently. CONCLUSION: The reliability and validity of the 'Adolescent physical exercise behavior-psychological scales (Chinese version) ' were good, and could be used to measure the adolescent's physical training behavior-psychological conditions.

THAP11, a novel binding protein of PCBP1, negatively regulates CD44 alternative splicing and cell invasion in a human hepatoma cell line.

THAP11 is an essential factor involved in ES cell pluripotency and cell growth. Here, we identified THAP11 as a novel physiological binding partner of PCBP1. In HepG2 cells, THAP11 overexpression inhibited CD44 v6 expression and cell invasion. However, when deleting the binding domain with PCBP1 or endogenous PCBP1 was knocked down, THAP11 failed to inhibit CD44 v6 expression, indicating that THAP11 regulates CD44 v6 expression through interacting with PCBP1. In HCC patients, the expression of THAP11 mRNA significantly correlated with PCBP1 mRNA expression. Our results suggest a novel role of THAP11 in CD44 alternative splicing and hepatoma invasion.

PCBP-1 regulates alternative splicing of the CD44 gene and inhibits invasion in human hepatoma cell line HepG2 cells.

BACKGROUND: PCBP1 (or alpha CP1 or hnRNP E1), a member of the PCBP family, is widely expressed in many human tissues and involved in regulation of transcription, transportation process, and function of RNA molecules. However, the role of PCBP1 in CD44 variants splicing still remains elusive. RESULTS: We found that enforced PCBP1 expression inhibited CD44 variants expression including v3, v5, v6, v8, and v10 in HepG2 cells, and knockdown of endogenous PCBP1 induced these variants splicing. Invasion assay suggested that PCBP1 played a negative role in tumor invasion and re-expression of v6 partly reversed the inhibition effect by PCBP1. A correlation of PCBP1 down-regulation and v6 up-regulation was detected in primary HCC tissues. CONCLUSIONS: We first characterized PCBP1 as a negative regulator of CD44 variants splicing in HepG2 cells, and loss of PCBP1 in human hepatic tumor contributes to the formation of a metastatic phenotype.
