ABSTRACT
OBJECTIVE: The traumatic experience of cancer, in addition to its negative impact on breast cancer patients, can also bring about positive change, i.e., post-traumatic growth (PTG). PTG can help boost patients' confidence in their fight against the disease and improve their adherence to treatment, thereby facilitating their recovery. The study aimed to investigate the effect of perceived stress on the PTG of patients undergoing postoperative chemotherapy for breast cancer and to examine the roles of rumination and self-efficacy between two. METHODS: The data was collected using a cross-sectional design. From December 2021 to October 2022, a total of 306 breast cancer patients who had undergone chemotherapy following surgery and met the inclusion and exclusion criteria were selected from three tertiary-level A hospitals in Henan Province, China. We conducted descriptive analysis, Pearson correlation analysis, and a regression analysis using PROCESS Macro Model 80 to explore the relationships among perceived stress, rumination, self-efficacy, and PTG. RESULTS: Perceived stress of patients undergoing postoperative chemotherapy for breast cancer had a negative predictive effect on PTG (r = -0.340, P < 0.01); Rumination and self-efficacy played a partial mediating effect between perceived stress and PTG, accounting for 45.25% of the total effect. CONCLUSIONS: Clinical nursing staff could promote PTG by strengthening psychological assessment and timely psychological intervention for patients with high perceived stress levels, encourage patients to adopt a positive way of thinking about illness and improve their self-efficacy level, so as to improve their PTG level.

Amdoparvoviruses infect various carnivores, including mustelids, canids, skunks, and felids. Aleutian mink disease virus (AMDV) belongs to the prototypical species Amdoparvovirus carnivoran1. Here, we identified a novel amdoparvovirus in farmed Asian badgers (Meles meles), and we named this virus "Meles meles amdoparvovirus" (MMADV). A total of 146 clinical samples were collected from 134 individual badgers, and 30.6% (41/134) of the sampled badgers tested positive for amdoparvovirus by PCR. Viral DNA was detected in feces, blood, spleen, liver, lung, and adipose tissue from these animals. Viral sequences from eight samples were determined, five of which represented nearly full-length genome sequences (4,237-4,265 nt). Six serum samples tested positive by PCR, CIEP, and IAT, four of which had high antibody titers (> 512) against AMDV-G. Twenty-six of the 41 amdoparvovirus-positive badgers showed signs of illness, and necropsy revealed lesions in their organs. Sequence comparisons and phylogenetic analysis of the viral NS1 and VP2 genes of these badger amdoparvoviruses showed that their NS1 proteins shared 62.6%-88.8% sequence identity with known amdoparvoviruses, and they clustered phylogenetically into two related clades. The VP2 proteins shared 76.6%-97.2% identity and clustered into two clades, one of which included raccoon dog and arctic fox amdoparvovirus (RFAV), and the other of which did not include other known amdoparvoviruses. According to the NS1-protein-based criterion for parvovirus species demarcation, the MMADV isolate from farm YS should be classified as a member of a new species of the genus Amdoparvovirus. In summary, we have discovered a novel MMADV and other badger amdoparvoviruses that naturally infect Asian badgers and are possibly pathogenic in badgers.

OBJECTIVES: Diabetic ketoacidosis (DKA) is a serious complication in patients treated with sodium-glucose co-transporter 2 inhibitors (SGLT2i). The aim of this study was to investigate the relationship between SGLT2i and the risk of DKA, and to identify high-risk groups and characteristics that should be emphasised. METHODS: A retrospective case series study was conducted to collect medical records of inpatients diagnosed with DKA and using SGLT2i before the onset of the disease from September 2022 to September 2023 in a tertiary hospital in Shanghai. Cases that met the inclusion criteria were retrieved through the electronic medical record system. Information was collected to compare the risk of DKA in patients with different characteristics. RESULTS: A total of 21 patients (12 men and 9 women) met the criteria for SGLT2i-associated DKA. The mean diabetes duration was 10.4 years, with 47.6% (10/21) of patients diagnosed with euglycaemic DKA. The drug treatment regimen most commonly used was the combination of SGLT2i and metformin, representing 52.4% (11/21) of cases. The most common clinical symptoms were nausea, vomiting, abdominal pain and malaise. Common predisposing factors were acute infections, acute pancreatitis (predominantly hyperlipidaemic type), dietary inappropriateness, acute cardiovascular and cerebrovascular events and surgery. 71.4% of patients (15/21) had multiple risk factors. CONCLUSION: The use of SGLT2i in diabetic patients is associated with an increased risk of DKA, particularly in the presence of predisposing factors such as infection. Furthermore, long diabetes duration, decreased pancreatic ß-cell function and the combined use of metformin may also contribute to the risk of DKA in patients treated with SGLT2i. The findings of this study provide valuable insights for better identification and management of DKA risks associated with SGLT2i in clinical practice.
ABSTRACT
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.
ABSTRACT
To explore whether granulosa cell (GC)-derived exosomes (GC-Exos) and follicular fluid-derived exosomes (FF-Exos) have functional similarities in follicle development and to establish relevant experiments to validate whether GC-Exos could serve as a potential substitute for follicular fluid-derived exosomes to improve folliculogenesis. GC-Exos were characterized. MicroRNA (miRNA) profiles of exosomes from human GCs and follicular fluid were analyzed in depth. The signature was associated with folliculogenesis, such as phosphatidylinositol 3 kinases-protein kinase B signal pathway, mammalian target of rapamycin signal pathway, mitogen-activated protein kinase signal pathway, Wnt signal pathway, and cyclic adenosine monophosphate signal pathway. A total of five prominent miRNAs were found to regulate the above five signaling pathways. These miRNAs include miRNA-486-5p, miRNA-10b-5p, miRNA-100-5p, miRNA-99a-5p, and miRNA-21-5p. The exosomes from GCs and follicular fluid were investigated to explore the effect on folliculogenesis by injecting exosomes into older mice. The proportion of follicles at each stage is counted to help us understand folliculogenesis. Exosomes derived from GCs were isolated successfully. miRNA profiles demonstrated a remarkable overlap between the miRNA profiles of FF-Exos and GC-Exos. The shared miRNA signature exhibited a positive influence on follicle development and activation. Furthermore, exosomes derived from GCs and follicular fluid promoted folliculogenesis in older female mice. Exosomes derived from GCs had similar miRNA profiles and follicle-promoting functions as follicular fluid exosomes. Consequently, GC-Exos are promising for replacing FF-Exos and developing new commercial reagents to improve female fertility.

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.
ABSTRACT
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.
ABSTRACT
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.

AIM: The aim of this study was to examine the chain mediating effects of self-efficacy and positive coping style on the relationship between parenting style and learning motivation in Chinese nursing students. BACKGROUND: Despite the abundance of literature that focuses on learning motivation, there is a lack of research that accurately and thoroughly examines the factors that influence learning motivation among nursing students. DESIGN: This study involved a cross-sectional design. METHODS: In total, 677 Chinese undergraduate nursing students completed the parental bonding instrument, the general self-efficacy scale, the simplified coping style questionnaire, and the learning motivation scale. A structural equation model was performed with AMOS 26.0 to explore the influence paths of variables and the mediating effects of self-efficacy and coping style. RESULTS: Parental care positively predicted intrinsic learning motivation directly or indirectly through the mediating effects of self-efficacy (B = 0.17, 95% CI: 0.12-0.23) and positive coping style (B = 0.03, 95% CI: 0.01-0.06), and this mediating effect contributed 54.06% of the total effect. Parental encouraging autonomy positively predicted intrinsic learning motivation indirectly through the mediating effects of self-efficacy (B = 0.17, 95% CI: 0.12-0.24) and positive coping style (B = 0.03, 95% CI: 0.01-0.06), and this mediating effect contributed 71.42% of the total effect. Parental control negatively influenced intrinsic learning motivation directly or indirectly through the mediating effects of self-efficacy (B = -0.10, 95% CI: -0.15 to -0.04) and positive coping style (B = -0.02, 95% CI: -0.05 to -0.01), and this mediating effect contributed 42.85% of the total effect. CONCLUSION: Parents should provide more care and autonomy to nursing students and reduce control over them. Nurse educators should consider targeted improvement strategies to improve the level of self-efficacy and positive coping style of nursing undergraduates to enable them to maintain a more intrinsic learning motivation.

ABSTRACT
Taurine, a sulfur-containing amino acid, has a wide range of biological effects, such as bile salt formation, osmotic regulation, oxidative stress inhibition, immunomodulation and neuromodulation. Taurine has been proved to be synthesized and abundant in male reproductive organs. Recently, accumulating data showed that taurine has a potential protective effect on reproductive function of male animals. In physiology, taurine can promote the endocrine function of the hypothalamus-pituitary-testis (HPT) axis, testicular tissue development, spermatogenesis and maturation, delay the aging of testicular structure and function, maintain the homeostasis of the testicular environment, and enhance sexual ability. In pathology, taurine supplement may be beneficial to alleviate pathological damage of male reproductive system, including oxidative damage of sperm preservation in vitro, testicular reperfusion injury and diabetes -induced reproductive complications. In addition, taurine acts as a protective agent against toxic damage to the male reproductive system by exogenous substances (e.g., therapeutic drugs, environmental pollutants, radiation). Related mechanisms include reduced oxidative stress, increased antioxidant capacity, inhibited inflammation and apoptosis, restored the secretory activity of the HPT axis, reduced chromosomal variation, enhanced sperm mitochondrial energy metabolism, cell membrane stabilization effect, etc. Therefore, this article reviewed the protective effect of taurine on male reproductive function and its detailed mechanism, in order to provide reference for further research and clinical application.

Interleukin 22 (IL-22) has an important role in colorectal tumorigenesis and many colorectal diseases such as inflammatory bowel disease and certain infections. However, the regulation of IL-22 production in the intestinal system is still unclear. Here, we present evidence that butyrophilin-like protein 2 (BTNL2) is required for colorectal IL-22 production, and BTNL2 knockout mice show decreased colonic tumorigenesis and more severe colitis phenotypes than control mice due to defective production of IL-22. Mechanistically, BTNL2 acts on group 3 innate lymphoid cells (ILC3s), CD4+ T cells, and γδ T cells to promote the production of IL-22. Importantly, we find that a monoclonal antibody against BTNL2 attenuates colorectal tumorigenesis in mice and that the mBTNL2-Fc recombinant protein has a therapeutic effect in a dextran sulfate sodium (DSS)-induced colitis model. This study not only identifies a regulatory mechanism of IL-22 production in the colorectal system but also provides a potential therapeutic target for the treatment of human colorectal cancer and inflammatory bowel diseases.

This study aimed to explore the effect of prosocial behaviours on Chinese undergraduate nursing students' subjective well-being (SWB) and examine the roles of psychological resilience and coping styles. The sample for this study included 683 nursing students from two undergraduate universities in Henan Province, China. SWB, prosocial behaviours, psychological resilience, and coping styles were assessed by the Index of Well-Being, the Prosocial Behavioural Tendency Scale, the Connor-Davidson Resilience Scale, and the Simplified Coping Style Questionnaire, respectively. We adopted Pearson's correlation analysis and the PROCESS Macro Model 81 in regression analysis to explore the relationships among prosocial behaviours, psychological resilience, coping styles, and SWB. Prosocial behaviours of undergraduate nursing students had a positive predictive effect on SWB; psychological resilience and coping styles both were the mediating variable between prosocial behaviours and undergraduate nursing students' SWB; psychological resilience and coping styles played a chain mediating role between the prosocial behaviours and SWB of undergraduate nursing students. The results indicated that prosocial behaviours not only directly affected the SWB of undergraduate nursing students but also affected the SWB of undergraduate nursing students via psychological resilience and coping styles. These results offer certain theoretical support and guidance for the research and improvement of undergraduate nursing students' SWB and emphasize the importance of interventions to increase prosocial behaviours, improve psychological resilience, promote positive coping styles, and address negative coping styles.

BACKGROUND: In the information age, the use of the internet and multimedia tools has large effects on the life of middle school students. Improper use of the internet may result in internet addiction (IA). Thus, actively exploring the factors influencing adolescent and the mechanism of addiction as well as promoting adolescent physical and mental health and academic development are priorities that families, schools, and society urgently need to address. AIM: To explore the effect of childhood trauma on adolescent IA and to consider the roles of loneliness and negative coping styles. METHODS: A total of 11310 students from six junior high schools in Henan, China, completed the child trauma questionnaire, IA test, loneliness scale, and simple coping style questionnaire. In addition, data were collected from 1044 adolescents with childhood trauma for analysis with IBM SPSS 26.0 and AMOS 28.0; we examined the relationships among childhood trauma, IA, loneliness, and negative coping styles. RESULTS: We found that childhood trauma not only directly affected adolescents' IA but also affected IA through loneliness and negative coping styles. CONCLUSION: Therefore, this study has theoretical implications regarding adolescent mental health and may inform interventions for IA.
ABSTRACT
BACKGROUND: How to kindle the learning enthusiasm of nursing students and reduce the incidence of academic procrastination is an important factor in reducing student attrition and improving the quality of nursing education. OBJECTIVES: To investigate the mediating role of coping style and resilience on the association between parenting styles and academic procrastination among nursing undergraduates. METHODS: A cross-sectional study of 683 nursing undergraduates was conducted in China from March to May 2022. Parenting styles, coping style, resilience, and academic procrastination were measured using questionnaires. Descriptive analysis, Pearson's correlation analysis and Hayes' PROCESS Macro in SPSS 25.0 were used to test the model. RESULTS: Positive parenting style had a significantly direct effect on academic procrastination and through three significantly indirect pathways: (1) through positive coping style (B = - 0.048, 95% CI: - 0.074 to - 0.025), accounting for 14.71% of the total effect; (2) through negative coping style (B = - 0.044, 95% CI: - 0.071 to - 0.021), accounting for 13.64% of the total effect; and (3) through resilience (B = - 0.074, 95% CI: - 0.107 to - 0.044), accounting for 22.82% of the total effect. Moreover, negative parenting style had a significantly direct effect on academic procrastination and through two significantly indirect pathways: (1) through negative coping style (B = 0.056, 95% CI: 0.032 to 0.086), accounting for 21.73% of the total effect, and (2) through resilience (B = 0.028, 95% CI: 0.004 to 0.055), accounting for 10.93% of the total effect. CONCLUSIONS: Intervention measures to reduce the academic procrastination of nursing undergraduates should include the evaluations of coping styles and resilience of nursing students and cultivation strategies to promote their positive coping styles and resilience.
ABSTRACT
Background: Previous studies have not investigated the role of resilience and coping style on the association between maladaptive perfectionism and academic procrastination among nursing undergraduates. However, how to mobilize the learning enthusiasm of nursing students and reduce the incidence of academic procrastination is an important factor to reduce nursing loss and improve nursing quality. Objectives: To investigate the influence of maladaptive perfectionism, resilience and coping style on academic procrastination among Chinese undergraduate nursing students. Methods: A cross-sectional study was conducted. A convenience sampling method was used to select 665 nursing undergraduates from March to May 2022 in China. Maladaptive perfectionism, coping style, resilience, and academic procrastination were measured using questionnaires. The descriptive analysis, Pearson's correlation analysis and the Hayes' PROCESS Macro in SPSS 25.0 were used to test the model. Results: The results showed that nursing undergraduates' maladaptive perfectionism, resilience, positive coping style and academic procrastination were significantly correlated between every two variables, with coefficients ranging between -0.290 and 0.584. In addition, resilience played a partial mediating role in maladaptive perfectionism and academic procrastination, accounting for 15.70% of the total effect; in the meantime, this process was moderated by positive coping style. Conclusion: Maladaptive perfectionism positively predicted nursing undergraduates' academic procrastination; as a mediating mechanism with moderating, resilience and positive coping style further explained how maladaptive perfectionism promoted the academic procrastination of nursing undergraduates. Understanding this mechanism is of great significance for nursing educators to reduce the risk of academic procrastination in nursing undergraduates.
ABSTRACT
Tissue and organ ischemia can lead to cell trauma, tissue necrosis, irreversible damage, and death. While intended to reverse ischemia, reperfusion can further aggravate an ischemic injury (ischemia-reperfusion injury, I/R injury) through a range of pathologic processes. An I/R injury to one organ can also harm other organs, leading to systemic multiorgan failure. A type of carotenoid, lycopene, has been shown to treat and prevent many diseases (e.g., rheumatoid arthritis, cancer, diabetes, osteoporosis, male infertility, neurodegenerative diseases, and cardiovascular disease), making it a hot research topic in health care. Some recent researches have suggested that lycopene can evidently ameliorate ischemic and I/R injuries to many organs, but few clinical studies are available. Therefore, it is essential to review the effects of lycopene on ischemic and I/R injuries to different organs, which may help further research into its potential clinical applications.

Posttraumatic growth (PTG) has been correlated with coping style among patients with breast cancer. However, to date, there is no consensus on the extent to which coping style is associated with PTG in patients with breast cancer. Therefore, we performed a meta-analysis to quantitatively synthesize previous findings. Based on the PRISMA method, this study employed a random effects model using the Stata software (version 16.0) to calculate the pooled correlation coefficient and examined a range of moderators: cancer stage, publication type, participants' age, and coping style measurement tools. Relevant studies, published from inception to 9 March 2022, were identified through a systematic search in PubMed, Embase, Web of Science, PsycINFO, WANFANG DATA, Chinese National Knowledge Infrastructure (CNKI), and China Science and Technology Journal Database (VIP) databases. Finally, 20 studies involving 3,571 breast cancer patients were included in this investigation. The results showed a high positive relation between confrontation coping and PTG and a moderate positive relation between avoidance coping and PTG (confrontation: r = 0.456; avoidance: r = 0.291). Additionally, a moderate negative relation was identified between acceptance-resignation coping and PTG (r = -0.289). Publication type and coping style measurement tools moderated the relation between coping style and PTG among breast cancer patients. The findings indicated that breast cancer patients should either confront the disease or avoid coping with it according to their disease state, which would facilitate better growth. More studies, especially, large prospective studies, are warranted to verify our findings.
