RESUMEN

OBJECTIVE: To investigate the relationship between work readiness and work well-being for newly graduated nurses and the mediating role of emotional labor and psychological capital in this relationship. METHODS: A cross-sectional survey was conducted in mainland China. A total of 478 newly graduated nurses completed the Work Readiness Scale, Emotional Labour Scale, Psychological Capital Questionnaire, and Work Well-being Scale. Descriptive statistical methods, Pearson correlation analysis, and a structural equation model were used to analyze the available data. RESULTS: Newly graduated nurses' work readiness was significantly positively correlated with work well-being (r = 0.21, p < 0.01), deep acting (r = 0.11, p < 0.05), and psychological capital (r = 0.18, p < 0.01). Emotional labor and psychological capital partially mediated the relationship between work readiness and work well-being. Additionally, emotional labor and psychological capital had a chain-mediating effect on the association. CONCLUSIONS AND CLINICAL RELEVANCE: Work readiness not only affects newly graduated nurses' work well-being directly but also indirectly through emotional labor and psychological capital. These results provide theoretical support and guidance for the study and improvement of newly graduated nurses' work well-being and emphasize the importance of intervention measures to improve work readiness and psychological capital and the adoption of deep-acting emotional-labor strategies.

RESUMEN

INTRODUCTION: Influenza infections are challenging to monitor at the population level due to many mild and asymptomatic cases and similar symptoms to other common circulating respiratory diseases, including COVID-19. Methods for tracking cases outside of typical reporting infrastructure could improve monitoring of influenza transmission dynamics. Influenza shedding into wastewater represents a promising source of information where quantification is unbiased by testing or treatment-seeking behaviours. METHODS: We quantified influenza A and B virus loads from influent at Switzerland's three largest wastewater treatment plants, serving about 14% of the Swiss population (1.2 million individuals). We estimated trends in infection incidence and the effective reproductive number (Re) in these catchments during a 2021/22 epidemic and compared our estimates to typical influenza surveillance data. RESULTS: Wastewater data captured the same overall trends in infection incidence as laboratory-confirmed case data at the catchment level. However, the wastewater data were more sensitive in capturing a transient peak in incidence in December 2021 than the case data. The Re estimated from the wastewater data was roughly at or below the epidemic threshold of 1 during work-from-home measures in December 2021 but increased to at or above the epidemic threshold in two of the three catchments after the relaxation of these measures. The third catchment yielded qualitatively the same results but with wider confidence intervals. The confirmed case data at the catchment level yielded comparatively less precise R_e estimates before and during the work-from-home period, with confidence intervals that included one before and during the work-from-home period. DISCUSSION: Overall, we show that influenza RNA in wastewater can help monitor nationwide influenza transmission dynamics. Based on this research, we developed an online dashboard for ongoing wastewater-based influenza surveillance in Switzerland.

RESUMEN

BACKGROUND: The level of nurses' job performance has always been of great concern, which not only represents the level of nursing service quality but is also closely related to patients' treatment and prognosis. The aim of this study was to analyze the relationship between perceived organizational justice and job performance and to explore the mediating role of organizational climate and job embeddedness among young Chinese nurses. METHODS: A cross-sectional survey of 1136 young nurses was conducted between March and May 2023 using convenience sampling. Data were collected using the Job Performance Scale, Organizational Justice Assessment Scale, Nursing Organizational Climate Scale, and Job Embeddedness Scale, and the resulting data were analyzed using SPSS 25.0 and AMOS 26.0. RESULTS: There was a significant positive correlation between job performance and perceived organizational justice (r = 0.477, p < 0.01), organizational climate (r = 0.500, p < 0.01), and job embeddedness (r = 0.476, p < 0.01). Organizational climate and job embeddedness acted as chain mediators between perceived organizational justice and job performance. The total effect of perceived organizational justice on job performance (ß = 0.513) consisted of a direct effect (ß = 0.311) as well as an indirect effect (ß = 0.202) mediated through organizational climate and job embeddedness, with the mediating effect accounting for 39.38% of the total effect. CONCLUSIONS: Organizational climate and job embeddedness play a chain mediating role between perceived organizational justice and job performance, so hospital managers should pay attention to the level of perceived organizational justice among young nurses, and develop a series of targeted measures to improve their job performance using organizational climate and job embeddedness as entry points.

RESUMEN

BACKGROUND: New nurses are prone to workplace deviant behavior in the constrained hospital environment, which will not only directly affect the safety of patients, but also reduce the work efficiency of nurses and bring negative results to the hospital. The purpose of this study was to investigate the relationship between perceived organizational justice, emotional labor, psychological capital, and workplace deviant behavior of new nurses. METHODS: A cross-sectional study was used in this study. A survey was conducted in 5 hospitals in Henan Province, Chain from February to April 2023. The sample size was 546. The questionnaire included general information, perceived organizational justice scale, emotional labor scale, psychological capital scale, and workplace deviant behavior scale. SPSS 26.0 and PROCESS Macro were used for data analysis. PROCESS Model 4 and Model 14 were used to verify the model. RESULTS: This study displays that perceived organizational justice was negatively correlated with emotional labor and workplace deviant behavior, and emotional labor was positively correlated with workplace deviant behavior. Meanwhile, emotional labor plays a partial mediating role between perceived organizational justice and workplace deviant behavior, accounting for 32.7% of the total effect. Moreover, the path of emotional labor on workplace deviant behavior is moderated by psychological capital. CONCLUSION: This study further understood the workplace deviant behavior of new nurses, and provided a new perspective for solving this problem. Nurse managers can reduce workplace deviant behavior by enhancing the perceived organizational justice and psychological capital of new nurses and improving emotional labor.

RESUMEN

BACKGROUND: As a common psychological problem in cancer patients, illness uncertainty has attracted wide attention from scholars. Some studies have pointed out that the level of social support may affect illness uncertainty in patients with cancer, but the results of these studies remain controversial. OBJECTIVE: The aim of this study was to evaluate the correlation between illness uncertainty and social support in patients with cancer using meta-analysis. METHODS: PubMed, Web of Science, EMBASE, EBSCO, Cochrane Library, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, and VIP Citation Database were searched for articles published up to 2022. The screening of the literature, data extraction, and quality assessment of the included studies were performed independently by 2 researchers. Stata 17.0 software was used to analyze the overall and moderation effects. RESULTS: Notably, 41 studies involving 5403 patients were included. The results showed that the illness uncertainty of adults with cancer was moderately negatively correlated with social support (r = -0.33). Country, publication year, cancer type, and instrument used to measure social support moderated the association between illness uncertainty and social support. CONCLUSION: Improving the level of social support can reduce illness uncertainty experienced by adults with cancer to a certain extent. IMPLICATIONS FOR PRACTICE: This review provides a clear direction for implementing precise interventions to reduce illness uncertainty among adults with cancer. Furthermore, patients with cancer with high morbidity and mortality rates deserve greater attention from healthcare personnel and family caregivers.

RESUMEN

Background & Aim: Non-suicidal self-injury (NSSI) in adolescents is a serious public health issue influenced by the interaction of multiple factors. The purpose of this study was to investigate the multiple mediating roles of alexithymia and self-esteem in the association between bullying victimization and NSSI in a sample of Chinese adolescents. Methods: A survey of 1299 adolescents from two public middle schools in Henan Province, China, was undertaken. Data were collected using the Chinese version of the Delaware bullying victimization scale-student (DBVS-S), the Toronto Alexithymia-20 Scale (TAS-20-C), the Rosenberg self-esteem scale (RSES), and the adolescent self-injury questionnaire. Besides, we performed a structural equation modeling (SEM) with latent variables using AMOS 26.0 to examine the relationship between variables and the mediating effects. Results: The SEM analysis found that not only can bullying victimization directly impact NSSI, but that alexithymia and self-esteem have a chain mediating effect in the association between bullying victimization and NSSI. This mediating effect contributed 22.47% to the total effect. Conclusion: These findings validate bullying victimization, alexithymia, and low self-esteem are important variables that affect NSSI among Chinese adolescents. Educators need to implement some prevention and intervention strategies to ameliorate the campus atmosphere and adolescents' mental health aimed at avoiding NSSI behavior in adolescence.

RESUMEN

During the SARS-CoV-2 pandemic, many countries directed substantial resources toward genomic surveillance to detect and track viral variants. There is a debate over how much sequencing effort is necessary in national surveillance programs for SARS-CoV-2 and future pandemic threats. We aimed to investigate the effect of reduced sequencing on surveillance outcomes in a large genomic data set from Switzerland, comprising more than 143k sequences. We employed a uniform downsampling strategy using 100 iterations each to investigate the effects of fewer available sequences on the surveillance outcomes: (i) first detection of variants of concern (VOCs), (ii) speed of introduction of VOCs, (iii) diversity of lineages, (iv) first cluster detection of VOCs, (v) density of active clusters, and (vi) geographic spread of clusters. The impact of downsampling on VOC detection is disparate for the three VOC lineages, but many outcomes including introduction and cluster detection could be recapitulated even with only 35% of the original sequencing effort. The effect on the observed speed of introduction and first detection of clusters was more sensitive to reduced sequencing effort for some VOCs, in particular Omicron and Delta, respectively. A genomic surveillance program needs a balance between societal benefits and costs. While the overall national dynamics of the pandemic could be recapitulated by a reduced sequencing effort, the effect is strongly lineage-dependent-something that is unknown at the time of sequencing-and comes at the cost of accuracy, in particular for tracking the emergence of potential VOCs.IMPORTANCESwitzerland had one of the most comprehensive genomic surveillance systems during the COVID-19 pandemic. Such programs need to strike a balance between societal benefits and program costs. Our study aims to answer the question: How would surveillance outcomes have changed had we sequenced less? We find that some outcomes but also certain viral lineages are more affected than others by sequencing less. However, sequencing to around a third of the original effort still captured many important outcomes for the variants of concern such as their first detection but affected more strongly other measures like the detection of first transmission clusters for some lineages. Our work highlights the importance of setting predefined targets for a national genomic surveillance program based on which sequencing effort should be determined. Additionally, the use of a centralized surveillance platform facilitates aggregating data on a national level for rapid public health responses as well as post-analyses.

RESUMEN

Objective: Many studies have explored the relationship between childhood trauma and internet addiction from different theoretical perspectives; however, the results have been inconsistent. The purpose of this meta-analysis was to examine the relationship between childhood trauma and internet addiction. Methods: The PubMed, Web of Science, Embase, CNKI, Wanfang and VIP electronic databases were searched to identify studies examining the correlation between childhood trauma and adolescent internet addiction. The databases were searched from inception to December 31, 2022. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias of the included studies. Then, Stata 17.0 software was used to perform meta-analysis. Results: This study was registered on PROSPERO (CRD42023388699). A total of 19 studies involving 21,398 adolescents were included in this meta-analysis. The random effects model was used for pooled analysis, and the results revealed a strong positive association between childhood trauma and internet addiction (r = 0.395, 95% CI [0.345, 0.442]). The relationship between childhood trauma and internet addiction was moderated by sample size, survey area, and internet addiction measurement tools. There were significant differences between the associations based on the various child trauma measurement tools and study quality scores. However, interstudy heterogeneity was not significantly affected by study year, sample source, or participant age. Conclusion: Internet addiction is positively correlated with childhood trauma. Therefore, it is extremely important for parents to provide a good growth environment during childhood to enhance the physical and mental development of adolescents. A warm family atmosphere helps individuals develop a healthy personality, thereby reducing or preventing the occurrence of internet addiction. Due to the limited number and low quality of the included studies, the above conclusions need to be verified by additional high-quality studies.

RESUMEN

WHAT IS KNOWN ABOUT THE SUBJECT?: Loneliness is common among young and middle-aged stroke survivors. It not only hinders the recovery of their neurological and physical functions but also increases the risk of stroke recurrence, disability, and even death. Improving the mental health of young and middle-aged stroke survivors is of utmost importance. However, previous research has not yet investigated the impact of interpersonal sensitivity and resilience on the relationship between stigma and feelings of loneliness. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: This study confirms that stigma has a positive impact on loneliness among young and middle-aged stroke survivors. Interpersonal sensitivity partially mediates the relationship between stigma and loneliness, and resilience plays a moderating role in the mediating mechanism. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Mental health nurses can formulate nursing interventions to reduce loneliness of young and middle-aged stroke survivors with the goals of improving stigma, reducing interpersonal sensitivity and cultivating resilience. ABSTRACT: Introduction Previous studies have not explored the impact of interpersonal sensitivity and resilience on the relationship between stigma and loneliness. However, improving the resilience of young and middle-aged stroke survivors and increasing their social participation is of great significance for reducing patients' loneliness of patients and promoting their physical and mental rehabilitation. Aims To investigate the influence of stigma, interpersonal sensitivity and resilience on loneliness among young and middle-aged stroke survivors. Methods A cross-sectional design was used to collect data. A total of 330 participants completed measures of stigma, resilience, interpersonal sensitivity and loneliness. The descriptive statistical approach, Pearson's correlation analysis and Hayes' PROCESS Macro Model 4 and 7 in regression analysis were used to analyse the available data. Results The results revealed that young and middle-aged stroke survivors' stigma, resilience, interpersonal sensitivity and loneliness were significantly correlated between every two variables, with coefficients ranging between -0.157 and 0.682. Interpersonal sensitivity played a partial mediating role in stigma and loneliness, accounting for 63.27% of the total effect; This process was moderated by resilience. Discussion Stigma positively predicts participants' loneliness. As a mediating mechanism with moderating, interpersonal sensitivity and resilience further explain how stigma affects loneliness. Implications for Practice Understanding this mechanism is of guiding significance to reduce loneliness of young and middle-aged stroke patients and promote their physical and mental rehabilitation.

RESUMEN

Ribonucleic acids (RNAs) enable disease-related gene inhibition, expression, and editing and represent promising therapeutics in various diseases. The efficacy of RNA relies heavily on the presence of a secure and effective delivery system. Herein, we found that RNA could be hydrophobized by cationic lipid and ionizable lipid and conveniently coassemble with amphiphilic polymer to achieve micelle-like nanoparticles (MNP). The results of the study indicate that MNP exhibits a high level of efficiency in delivering RNA. Besides, the MNP encapsulating siRNA that targets CD47 and PD-L1 remarkably blocked these immune checkpoints in a melanoma tumor model and elicited a robust immune response. Moreover, the MNP encapsulating the mRNA of OVA achieved antigen translation and presentation, leading to an effective antitumor immunoprophylaxis outcome against OVA-expressing melanoma model. Our findings suggest that RNA hydrophobization could serve as a viable approach for delivering RNA, thereby facilitating the exploration of RNA therapy in disease treatment.

RESUMEN

OBJECTIVE: A systematic review and meta-analysis was performed to identify the factors related to cancer death anxiety based on available evidence. DESIGN: This systematic review and meta-analysis followed the PRISMA 2020 guidelines. METHODS: Seven databases were searched to identify studies on the relationships of cancer death anxiety with demographic characteristics, disease factors and psychosocial factors from inception to May 2023. The Agency for Medical Research and Quality (AHRQ) scale was used to evaluate the quality of the included studies. After two researchers independently completed the literature search, data extraction and quality evaluation, meta-analysis was conducted by using RevMan5.3 and Stata 17.0 software. RESULTS: In total, 52 studies were included in this review. The results revealed that there were positive correlations of death anxiety with female sex, the symptom burden, anxiety levels, depression levels, fear of recurrence, attachment avoidance, psychological distress, resignation and confrontation coping. Death anxiety was negatively correlated with age, education level, ability to perform daily activities, self-esteem, spiritual well-being, sense of meaning in life, resilience, quality of life, social support and religious beliefs. CONCLUSIONS: Our results can inform the design of interventions to address death anxiety and improve the overall quality of life of cancer patients. Healthcare professionals should promptly identify and focus on death anxiety in high-risk populations of cancer patients. RELEVANCE TO CLINICAL PRACTICE: Cancer patients commonly experience death anxiety, and this anxiety has a nonnegligible impact on patients' mental health and overall quality of life. This study can inform the development of interventions by clinical healthcare professionals. NO PATIENT OR PUBLIC CONTRIBUTION: This was a meta-analysis based on data from previous studies.

RESUMEN

Autophagy is a conservative self-degradation system, which includes the two major processes of enveloping abnormal proteins, organelles and other macromolecules, and transferring them into lysosomes for the subsequent degradation. It holds the stability of the intracellular environment under stress. So far, three types of autophagy have been found: microautophagy, chaperone-mediated autophagy and macroautophagy. Many diseases have the pathological process of autophagy dysfunction, such as nervous system diseases. Pyroptosis is one kind of programmed cell death mediated by gasdermin (GSDM). In this process of pyroptosis, the activated caspase-3, caspase-4/5/11, or caspase-1 cleaves GSDM into the N-terminal pore-forming domain (PFD). The oligomer of PFD combines with the cell membrane to form membrane holes, thus leading to pyroptosis. Pyroptosis plays a key role in multiple tissues and organs. Many studies have revealed that autophagy and pyroptosis participate in the nervous system, but the mechanisms need to be fully clarified. Here, we focused on the recent articles on the role and mechanism of pyroptosis and autophagy in the pathological processes of the nervous system.

RESUMEN

BACKGROUND: With the continuous improvement of people's health needs, the public's requirements for medical care are also getting higher and higher. Work engagement is a positive psychological state related to the work. It is very important to maintain nurses' work engagement, however, due to many factors, the level of nurses' work engagement is not high and nursing managers should identify the influencing factors of work engagement, and take positive measures to fully improve nurses' work engagement. OBJECTIVES: To explore the influence of compassion fatigue, professional identity and sense of coherence on nurses' work engagement. METHODS: From January 2022 to June 2022, convenience sampling was used to select clinical nurses from 9 tertiary hospitals in Henan Province of China as the research objects for a questionnaire survey. Statistical methods included descriptive statistical analysis, Pearson correlation analysis and the PROCESS Macro Model 4 and 7 in regression analysis. RESULTS: The results showed that compassion fatigue was significantly negatively correlated with sense of coherence, professional identity and work engagement (P<0.01), professional identity was significantly positively correlated with sense of coherence and work engagement (P<0.01), and there was a significant positive correlation between sense of coherence and work engagement (P<0.01). Professional identity played a partial mediating role between compassion fatigue and work engagement, accounting for 46.40% of the total effect; meanwhile, sense of coherence moderated the effect of compassion fatigue on professional identity and formed a moderated mediation model. CONCLUSIONS: Compassion fatigue has a negative predictive effect on nurses' work engagement. Professional identity and sense of coherence further explained the relationship of compassion fatigue on compassion fatigue and work engagement through mediating and moderating effects.

RESUMEN

In this study, the authors provide results of the precisely synchronized triggering of an intense electron beam accelerator (IEBA). The trigger generator was composed of a fractional-turn ratio saturable-pulse transformer and a compact six-stage Marx generator. The main switch of the IEBA was a corona-stabilized triggered switch (CSTS) based on the stabilized corona mechanism. The output voltage of a single IEBA exceeded 500 kV with less than 4 ns of jitter on a 50 Ω dummy load. We also conducted an experiment on the synchronous triggering of two IEBAs by using two independent trigger generators. The synchronization-related jitter was 6.1 ns, while the average time difference was 1.3 ns. We used this to attempt to trigger two parallel IEBAs by using a single trigger generator. The results showed a reduction in the synchronization-related jitter of 31% to 4.2 ns. The designs of the CSTS and the trigger generator guaranteed a precisely synchronous trigger by using a single trigger generator. Thus, the proposed method appears to be promising for accurately and synchronously triggering multiple IEBAs by using a single trigger generator. This provides an effective method to generate pulses with high power.

RESUMEN

Efficiently reawakening immune cells, including T cells and macrophages, to eliminate tumor cells is a promising strategy for cancer treatment, but remains a huge challenge nowadays. Herein, a nanoassembly formed by doxorubicin (DOX)-conjugated polyphosphoester (PP-(hDOX)) and CD47-targeting siRNA (siCD47) via electrostatic and π-π stacking interactions, termed as PP-(hDOX&siCD47), was developed to reawaken the T cell and macrophage-mediated anticancer activity. The PP-(hDOX&siCD47) could efficiently blockade antiphagocytic signal by downregulation of CD47 expression to reactive macrophage-mediated anticancer immunotherapy. Moreover, the conjugated DOX of PP-(hDOX&siCD47) can perform the chemotherapy towards tumor cells and also elicit the T cell-mediated anticancer immune response via immunogenic cell death (ICD) effect. Therefore, the PP-(hDOX&siCD47) treatment could significantly increase M1-like macrophages proportion and tumor infiltration of CD8+ T cells, while the proportions of regulatory T cells (Treg) and myeloid-derived suppressor cells (MDSC) were considerably reduced in tumor tissue, eventually achieving significantly tumor growth inhibition. Overall, this study provides a simple siRNA and DOX codelivery approach to simultaneously elicit the macrophage- and T cell-mediated anticancer immune response for cancer therapy.

RESUMEN

Acute kidney injury (AKI) is closely associated with the overproduction of reactive oxygen species (ROS), which can cause multiple organ dysfunctions without timely treatment. However, only supportive treatments are currently available for AKI in clinics. Here, we developed nanomaterials of hyperbranched polyphosphoester (PPE) containing abundant thioether (S-PPE NP) and thioketal bonds (TK-PPE NP). Our data demonstrates that S-PPE NP exhibits an excellent capability of absorbing and scavenging multiple types of ROS, including H2O2, •OH, and •O2-, via thioether oxidation to sulfone or sulfoxide; it was also determined that S-PPE NP efficiently eliminates intracellular ROS, thus preventing cellular damage. Moreover, S-PPE NP was able to efficiently accumulate in the injured kidneys of AKI-bearing mice. As a result, the administration of S-PPE NP provided a superior therapeutic effect in AKI-bearing mice by downregulating ROS- and inflammation-related signaling pathways, thus reducing cell apoptosis. This thioether-containing polymer represents a promising broad-spectrum ROS scavenger that can be used for effective AKI treatments.

RESUMEN

The nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome is an important part of the natural immune system that plays an important role in many diseases. Estrogen is a sex hormone that plays an important role in controlling reproduction and regulates many physiological and pathological processes. Recent studies have indicated that estrogen is associated with disease progression. Estrogen can ameliorate some diseases (e. g, sepsis, mood disturbances, cerebral ischemia, some hepatopathy, Parkinson's disease, amyotrophic lateral sclerosis, inflammatory bowel disease, spinal cord injury, multiple sclerosis, myocardial ischemia/reperfusion injury, osteoarthritis, and renal fibrosis) by inhibiting the NLRP3 inflammasome. Estrogen can also promote the development of diseases (e.g., ovarian endometriosis, dry eye disease, and systemic lupus erythematosus) by upregulating the NLRP3 inflammasome. In addition, estrogen has a dual effect on the development of cancers and asthma. However, the mechanism of these effects is not summarized. This article reviewed the progress in understanding the effects of estrogen on the NLRP3 inflammasome and its mechanisms in recent years to provide a theoretical basis for an in-depth study.

RESUMEN

BACKGROUND & AIMS: Diabetes may perceive or experience varying degrees of stigma and psychological distress. The association between diabetes-related stigma and psychological distress has been examined in many studies, but no research has used a quantitative synthesis method to investigate the severity of this association and the moderators of the relationship. Thus, we conducted a meta-analysis to quantitatively integrate previous findings to identify the magnitude of the association between stigma and psychological distress among people with diabetes. REVIEW METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines, we systematically searched four English academic databases (PubMed, Embase, Web of Science, and PsycINFO) and three Chinese databases (China National Knowledge Infrastructure [CNKI], WANFANG Data, China Science and Technology Journal Database [VIP]). The databases were searched from the inception of each database to the end of March 2023. The pooled correlation coefficient of the association between stigma and psychological distress among people with diabetes was calculated by a random effects model using Stata software (version 17.0), and several moderators that impacted this relationship were identified. RESULTS: Eligible studies (N = 19) with a total of 12,777 participants were analysed. The pooled correlation was high between diabetes-related stigma and psychological distress (r = 0.50, 95% CI: [0.43-0.57]). Moreover, the association was moderated by the diabetes stigma measurement tools and diabetes distress measurement tools used. However, the relationship was not moderated by type of diabetes, age, gender, geographical location, or type of stigma. CONCLUSIONS: The results of the meta-analysis showed that stigma is strongly related to psychological distress among people with diabetes. Longitudinal or experimental research should be expanded in the future to further identify the causal pathways in the relationship between diabetes stigma and diabetes distress.

RESUMEN

AIM: This study aims to explore the effect of organizational justice on young nurses' turnover intention and the roles of organizational climate and emotional labour in this relationship. BACKGROUND: The shortage of nursing resources has become a growing problem in countries worldwide. As the main representatives of the nursing force, young nurses have high turnover intentions, which aggravates the possibility of nursing shortages. As an important variable affecting the turnover intention of young nurses, the mechanism underlying the impact of organizational justice should be studied in depth. DESIGN: A descriptive cross-sectional design was employed. METHODS: From November to December 2022, an online questionnaire survey was conducted among 1160 young clinical nurses from 5 hospitals in Henan Province, China. The scales used in this study include the organizational justice scale, the turnover intention scale, the organizational climate scale and the emotional labour scale. AMOS 26.0 was used for model drawing and mediation path testing, and SPSS 25.0 was used for data analysis. This study complies with the STROBE Statement of Observational Studies. RESULTS: In general, the young nurses surveyed had high turnover intentions (14.82+/-4.44). Organizational justice has a negative predictive effect on young nurses' turnover intention (r = -0.465, P<0.01). Organizational climate and emotional labour play a chain mediating role in the relationship between organizational justice and young nurses' turnover intention (ß = -0.051). CONCLUSIONS: Organizational justice is significantly related to the turnover intention of young nurses, and organizational climate and emotional labour play a chain mediating role in the relationship between organizational justice and turnover intention. Therefore, nursing managers should pay attention not only to organizational justice but also to the influence of organizational climate and emotional labour on the turnover intention of young nurses.

RESUMEN

AIMS: This study aimed to investigate the associations between perfectionism and undergraduate nursing students' academic procrastination, the mediating effects of self-efficacy and the moderating role of resilience. DESIGN: A cross-sectional survey. METHODS: The survey was conducted from March to May 2022 with a sample of 587 undergraduate nursing students in two undergraduate universities in China. A descriptive statistical approach, Pearson's correlation analysis and the Hayes' PROCESS Macro model 4 and 14 were used to analyse the available data. RESULTS: Adaptive perfectionism and maladaptive perfectionism negatively and positively predicted academic procrastination in nursing undergraduates, respectively. Self-efficacy played a partially mediating role in the association between adaptive perfectionism and academic procrastination. Furthermore, resilience played a moderating role in the association between adaptive perfectionism and academic procrastination. CONCLUSIONS: Maladaptive perfectionism and low levels of resilience and self-efficacy may increase the risk of academic procrastination among nursing undergraduates. Nursing educators can take measures to decrease the risk of academic procrastination among nursing undergraduate students by guiding them to cultivate adaptive perfectionism tendencies and improve their self-efficacy and resilience. IMPACT: The findings of this study can be used to develop targeted coping and prevention measures for nursing educators to reduce the incidence of academic procrastination among nursing undergraduates. PATIENT OR PUBLIC CONTRIBUTION: Five hundred eighty-seven undergraduate nursing students from two undergraduate universities participated in the study and responded to questions on perfectionism and academic procrastination, etc.
