RESUMEN
Background: This study aims to analyze the relationship between psychological resilience, perceived organizational support, and intention to stay among nurses. Additionally, it explores the mediating role of perceived organizational support in the relationship between psychological resilience and nurses' intention to stay. Methods: A cross-sectional survey was conducted between August and September 2023, involving 1,402 nurses from five Grade 3A hospitals in Guangdong. The survey utilized several instruments, including the General Information Questionnaire (GIQ), the Chinese version of the Connor-Davidson Resilience Scale (CD-RISC), the Chinese version of the Perceived Organizational Support Scale (POSS), and the Chinese version of the Intention to Stay Scale (ITSS). The obtained data were analyzed using descriptive statistics and Pearson's correlation coefficient, while the mediating effect of perceived organizational support was assessed using the PROCESS macro mediation model in SPSS. Results: The overall mean score for psychological resilience among nurses in the five Grade 3A hospitals in Guangdong was 60.54 ± 19.17, the overall mean score for perceived organizational support was 45.77 ± 11.49, and the mean score for intention to stay was 20.82 ± 4.65. The results of the statistical analysis revealed positive correlations between psychological resilience and intention to stay (r = 0.388, p < 0.01), between perceived organizational support and psychological resilience (r = 0.570, p < 0.01), and between perceived organizational support and intention to stay (r = 0.550, p < 0.01). Additionally, perceived organizational support was found to mediate the relationship between psychological resilience and intention to stay, with a mediation effect value of 0.067, accounting for 71.28% of the total effect. Conclusion: Psychological resilience of nursing staff directly impacts their intention to stay and indirectly influences their caring behaviors, with perceived organizational support serving as a key mediator in both relationships. Therefore, nursing managers should implement targeted interventions to enhance nurses' psychological resilience and perceived organizational support. Strengthening these factors can significantly increase nurses' intention to stay in their jobs, improve the quality of care, and contribute to building a strong and stable nursing workforce.
RESUMEN
AIM: We aimed to examine the relationships among nurses' career compromise, job satisfaction, and turnover intention and the mediating role of job satisfaction in the relationship between career compromise and turnover intention. BACKGROUND: Nurses are prone to career compromise when there is a discrepancy between the reality of their job and their personal career expectations due to personal or family factors. High levels of career compromise may have a significant impact on turnover intentions through low job satisfaction, thereby affecting the stability of the nursing workforce. There is a paucity of research on the impact of nurses' career compromise on turnover intentions. METHOD: This was a cross-sectional research design of nurses in hospitals in Guangdong Province using a convenience sampling method. The Career Compromise Scale (CCS), Job Satisfaction Scale (JSS), and Turnover Intention Scale (TIS) were used. The obtained data were analyzed through descriptive statistics, Spearman's correlation coefficient, and the mediating effect of perceived organizational support was tested through the PROCESS macro mediation model in SPSS. RESULTS: Data from 821 nurses who met the inclusion criteria were analyzed. The total score of nurses' turnover intention was 14.68 ± 4.32. Spearman's correlation analysis showed that career compromise was negatively correlated with job satisfaction (r = -0.594, p < 0.01), job satisfaction was negatively correlated with turnover intention (r = -0.471, p < 0.01), and career compromise was positively correlated with turnover intention (r = 0.544, p < 0.01). The mediating effect of job satisfaction on the relationship between career compromise and turnover intention has been demonstrated. The mediating effect is significant, with a value of 0.056, representing 25.71% of the total effect. CONCLUSIONS: The turnover intention of nurses in Guangdong Province is high. Job satisfaction mediated the relationship between career compromise and turnover intention. This study further enriches JD-R theory and COR theory and provides new perspectives for nurse managers to develop intervention strategies to stabilize the nursing workforce and reduce turnover.

Objective: To investigate the current status of psychological resilience, insomnia and negative emotions among nurses in Guangdong Province, China. And to explore the effects of the interaction between psychological resilience and insomnia on negative emotions. Methods: A cross-sectional survey method was used to select 1874 nurses in Guangdong Province from February 2023 to April 2023 for the survey. The Chinese version of the Psychological Resilience Scale (PRS), Insomnia Severity Index (ISI), Depression Anxiety and Stress Scale-21(DASS-21)were used in this study. We use SPSS 26.0 for statistical analysis. A simple effect analysis was established to analyze the association between psychological resilience, insomnia and negative emotions by using psychological resilience, insomnia and the interaction term. Results: The overall PRS and ISI scores were (59.79 ± 17.29) and (9.83 ± 5.97). The scores of DASS-21 each dimension were (8.19 ± 9.02) for depression emotion,(7.93 ± 7.66) for anxiety emotion and (10.58 ± 9.77) for stress emotion. The results of the interaction effect analysis indicated that psychological resilience and insomnia exhibited statistically significant differences in the between-subjects effect test for depression emotion (r2 = 0.136, P<0.01), anxiety emotion (r2 = 0.127, P<0.01), and stress emotion (r2 = 0.142, P<0.01). Conclusion: The nurses exhibited moderate levels of psychological resilience. Most of them have varying degrees of insomnia, with majority being classified as mild insomnia. Additionally, they demonstrated varying degrees of negative emotions. There was a negative correlation between psychological resilience and insomnia. Psychological resilience was negatively correlated with depression, anxiety and stress emotions. Insomnia was positively correlated with depression, anxiety and stress emotions. Furthermore, the interaction between psychological resilience and insomnia had an effect on all three dimensions of negative emotions. Consequently, hospital administrators may implement efficacious intervention strategies such as cognitive behavioral therapy and improving workplace climate in a timely manner according to the different psychological tolerance and severity of insomnia of nurses in order to reduce the occurrence of negative emotions among nurses and improve their mental health.
RESUMEN
Cold stress severely restricts plant development, causing significant agricultural losses. We found a critical transcription factor network in Medicago ruthenica was involved in plant adaptation to low-temperature. APETALA2/ethylene responsive factor (AP2/ERF) transcription factor MrERF039 was transcriptionally induced by cold stress in M. ruthenica. Overexpression of MrERF039 significantly increased the glucose and maltose content, thereby improving the tolerance of M. ruthenica. MrERF039 could bind to the DRE cis-acting element in the MrCAS15A promoter. Additionally, the methyl group of the 14th amino acid in MrERF039 was required for binding. Transcriptome analysis showed that MrERF039 acted as a sugar molecular switch, regulating numerous sugar transporters and sugar metabolism-related genes. In addition, we found that MrERF039 could directly regulate ß-amylase gene, UDP glycosyltransferase gene, and C2H2 zinc finger protein gene expression. In conclusion, these findings suggest that high expression of MrERF039 can significantly improve the cold tolerance of M. ruthenica root tissues during cold acclimation. Our results provide a new theoretical basis and candidate genes for breeding new legume forage varieties with high resistance.

Introduction: Pfeiffer syndrome is a rare genetic disorder characterized by craniosynostosis, broad thumbs and big toes, and partial syndactyly of the hands and feet. This case report presents the case of a girl diagnosed with type 2 Pfeiffer syndrome who experienced severe obstructive sleep apnea (OSA). Case report: The patient had been using an oropharyngeal airway since the age of 4 months due to snoring and witnessed apnea during sleep. At 11 months old, she was referred to our sleep clinic because of growth limitation and gross motor ability issues. Polysomnography (PSG) showed severe obstructive hypopnea before any treatment, and revealed severe central sleep apnea with the oropharyngeal airway in place. Positive airway pressure (PAP) therapy was initiated, which improved both her sleep and gross motor ability. Conclusion: This case report emphasizes the importance of thorough sleep studies for diagnosing sleep and breathing disorders in Pfeiffer syndrome patients and highlights the effectiveness of PAP therapy in managing these conditions.
RESUMEN
BACKGROUND: Behcet's disease and Sjogren's syndrome is an autoimmune disorder from which many systems of the body can suffer. Here we reported a patient with a history of Behcet's disease and Sjogren's syndrome in which REM sleep behavior disorder (RBD) was then detected by polysomnographic (PSG) monitoring. CASE PRESENTATION: A 68-year-old male patient with a history of Behcet's disease and Sjogren's syndrome was diagnosed with RBD by clinical examination and video-PSG, and he also underwent a multiple sleep latency test and cerebral magnetic resonance imaging. The patient had a history of Behcet's disease for 20 years and Sjogren's syndrome for 2 years. The cerebral magnetic resonance imaging also suggested cerebral demyelination and mild cortical atrophy, with cognitive dysfunction by a score of 28 on the mini-mental state examination (MMSE) and a score of 22 on the Montreal cognitive assessment (MoCA). CONCLUSION: RBD is common in the elderly population and is significantly related to α-synucleinopathy. Combining the decline in neuro-cognition and mild cortical atrophy, presentation of RBD in this patient could indicate an underlying α-synucleinopathy neurodegenerative disorder in the future. Considering the role of inflammation in the pathogenesis of α-synucleinopathy and a common shared HLA allelic genes in RBD and Sjogren's syndrome, it is suggested that a physiological process which is related to neuroinflammation may be involved in the pathogenesis of RBD.
RESUMEN
OBJECTIVE: To investigate and analysis the prevalence and risk factors of snoring and excessive daytime sleepiness among male pilots. METHODS: 1108 subjects were derived from a random sample of pilots. They were asked to answer the questions from a questionnaire concerning their snoring and daytime sleepiness, etc. 1054 questionnaire were available for evaluation. RESULTS: The overall prevalence of snoring among male pilots was 51.04% (538/1054), while moderate and severe snorers accounted for 26.28% (227/1054). The prevalence of snoring among male pilots aged over 30 yr was 63.68% (426/669). The prevalence and severity of snoring increase with age and BMI. Age, overweight and obesity, alcohol ingestion and family history of snoring were associated with the prevalence and severity of snoring. There was significant difference in Epworth sleepiness scale scores among without snoring group and various severity of snoring groups (chi2 = 16.948, P < 0.05). CONCLUSION: The prevalence of snoring is high in male pilots. The Epworth sleepiness scale score increase with increasing degree of snoring. Doctors should pay more attention to snoring in male pilot.

OBJECTIVE: To assess the diagnostic value of oxygen saturation combined with airflow (OF) monitoring for diagnosis of obstructive sleep apnea hypopnea syndrome (OSAHS). METHODS: Sixty-two subjects including suspected OSAHS and non-snorers underwent overnight polysomnography (PSG) and OF monitoring simultaneously in sleep laboratory. The apnea-hypopnea index (AHI), lowest oxygen saturation (LSaO(2)), and oxygen desaturation index (ODI) recorded by OF were compared with those recorded by PSG. The AHI and ODI data that showed skew distribution underwent square root transformation to approximate to normal distribution. Pair t test was used for difference hypothesis test. The agreement between the two measures was analyzed using Bland-Altman plot. RESULTS: Forty-five of the 62 subjects were diagnosed as with OSAHS based on PSG with the mean AHI value of (40 +/- 27) events per hour. The mean AHI values derived from OF (OF-AHI) and PSG (PSG-AHI) according to total sleep time were (28 +/- 26) and (29 +/- 28) times per hour respectively, and those after square root transformation were (4.6 +/- 2.7) and (4.7 +/- 2.7) times per hour respectively (P = 0.08). The mean LSaO(2) derived from OF (OF-LSaO(2)) was (82 +/- 11)%, not significantly different from that derived from PSG (PSG-LSaO(2)) [(82 +/- 10)%, P = 0.65]. The ODI derived from OF (OF-ODI) after square root transformation was (3.0 +/- 2.4) times/h, significantly lower than that derived from PSG (PSG-ODI) after square root transformation [(4.0 +/- 2.9) times/h, P = 0.00]. The Bland-Altman plot revealed a good agreement between the OF-AHI and PSG-AHI in non-OSAHS people and patients with mild OSAHS (P = 0.28), however, the OF-AHI was lower than PSG-AHI (P = 0.00) in the patients with moderate to severe OSAHS. There was no significant difference between OF-LSaO(2) and PSG-LSaO2 (P = 0.65). CONCLUSIONS: There is a good agreement between OF and PSG for AHI and LSaO(2). OF can be used to screen patients with suspected OSAHS in high risk population. However, OF tends to underestimate the AHI in moderate to severe OSAHS so additional manual analysis is necessary to confirm the diagnosis.
