Aim. To explore the mediating effect of psychological empowerment in the association between transformational leadership and organizational citizenship behaviors in nursing context. Background. Healthcare organizations worldwide are facing unprecedented challenges, necessitating effective leadership strategies to ensure quality patient care and organizational success. Transformational leadership has emerged as a tool to promote positive workplace behaviors, including organizational citizenship behaviors, among nursing staff. However, the mediating role of psychological empowerment in this relationship remains underexplored. Methods. A cross-sectional survey was conducted from March 2023 until August 2023 involving 305 registered nurses at King Khalid Hospital to investigate the relationship among transformational leadership, psychological empowerment, and organizational citizenship behaviors. Validated scales were used to assess these variables. A single mediation analysis was conducted through processing macro version 3.5 model 4. Results. This study found a strong positive association between transformational leadership and both psychological empowerment (r = 0.507, ) and organizational citizenship behaviors (r = 0.445, ) among nursing staff. Additionally, psychological empowerment partially mediated the relationship between transformational leadership and organizational citizenship behaviors, with a significant indirect effect (B = 0.110, CI: 0.058–0.166). Conclusions. Transformational leadership positively impacted nurses’ feelings of empowerment, which then led to higher exhibition of organizational citizenship behaviors. Implications for Nursing Management. Leadership development programs should prioritize the cultivation of transformational leadership qualities and support the psychological empowerment of nursing staff. This approach can enhance organizational effectiveness, foster positive workplace environments, and improve patient outcomes.

Universities and colleges play a pivotal role in the pursuit of a future that is sustainable through their pedagogical efforts and the execution of state-of-the-art research endeavors aimed at mitigating the effects of climate change. Higher Education Institutions (HEIs) serve as crucial catalysts in advancing sustainable development. HEIs are increasingly embracing precise measures to reduce their carbon footprint (CF) while also educating students on global sustainability. These nano-methods provide a quantitative framework for assessing a campus's sustainability efforts in line with Green Campus (GC) initiatives to lower carbon emissions align with GC goals. This study employs K-means clustering to analyze the integration of green and low-carbon principles in higher education political and ideological studies. Its goal is to identify patterns, assess teaching effectiveness, and improve sustainability education, aligning with Green Campus initiatives to enhance institutional contributions to sustainable growth through informed pedagogical strategies. Input data includes curriculum content, teaching methods, student engagement, and institutional goals related to sustainability. Seeking to improve sustainability education align with Green Campus initiatives, higher education can strategically enhance their contributions to long-term sustainability and growth through effective pedagogical approaches. Cluster 3 has the lowest WCSS value of 1200, indicating tighter cohesion and less variability within this cluster compared to Cluster 1 (1500) and Cluster 2 (1800). Cluster 3 stands out with the highest silhouette score of 0.7, suggesting well-defined and distinct clusters, while Cluster 2 has the lowest score of 0.4, indicating some overlap or ambiguity in data points. Cluster 1 has the lowest Davies-Bouldin Index of 0.4, implying better separation between clusters compared to Cluster 2 (0.6) and Cluster 3 (0.5). Cluster 3 is well-defined and cohesive, showing strong integration of green practices. Cluster 1 displays good separation and cohesion, while Cluster 2 requires refinement due to potential overlap in sustainability integration.

Aim. The studys aim was to examine the relationship between transformational leadership, organizational justice, and nurses quality of work life. Background. There is an increasing emphasis on the welfare of nurses and their influence on healthcare services. There is a dearth of comprehensive studies on the influence of transformational leadership and justice within organizations on work-related quality of life. Understanding these connections is critical for improving workplace dynamics and fostering nurse well-being. Methods. This cross-sectional research included a convenience sample of nurses working in a general hospital. The data were obtained through self-report questionnaires encompassing three reliable and validated scales: the global transformational leadership scale, organizational justice scale, and quality of nursing work-life scale. The data were then analyzed with SPSS 23 and statistical methods (descriptive statistics, Pearson correlation coefficient, and hierarchical linear regression). This study adhered to the STROBE guidelines. Results. A sum of 527 out of 566 nurses responded to the questionnaires (response rate=93.1). The nurses had a high perception of transformational leadership behaviors but had a more moderate view of organizational fairness and the quality of their nursing work life. Transformational leadership was significantly associated with organizational fairness. Also, a positive relationship was found between transformational leadership, justice within organizations, and nurses quality of work life. Conclusions. Nurses who consider their leaders as transformative and have the sense of a fair organizational climate are more likely to have higher levels of quality of work life. Implications for Nursing Management. Nurse managers should strive to develop transformational leadership behaviors and promote organizational justice to enhance the well-being and satisfaction of nurses in their work environments.

Introduction: Exopolysaccharides (EPSs) derived from marine microorganisms are a newly recognized reservoir of bioactive therapeutic compoundsMaterial and methods: We isolated a high EPS-yielding bacterial strain from the Red Sea, identified as Bacillus rugosus SYG20. Its purified EPS (EPSR9) contains 45.33% uronic acid, 9.98% sulfate groups, and 5.40% N-acetyl glucosamine. The HPLC chromatogram revealed four monosaccharides - glucose, xylose, galacturonic acid, and arabinose, in a distinct molar ratio of 2:3:1:1. EPSR9 showed a wide array of bioactivities.Results: It displayed antioxidant activity with an IC50 of 25.6 μg/ml in the DPPH assay and a total antioxidant capacity (TAC) of 417.77μg/ml equivalent AAE and 62.67 μg/ml equivalent AAE in Ferric reducing antioxidant power (FRAP) assays. It exhibited substantial anti-inflammatory properties. The anticoagulant effect of the EPS was demonstrated by a dose-dependent increase in prothrombin time. The scratch assay resulted in a 72.66% increase in wound closure, promoting in vitro wound healing after 48 h. Anti-obesity activity was evidenced by 83.8% lipase inhibition at 1000 μg/ml with IC50 of 107.73μg/ml. EPSR9 demonstrated inhibitory effects on α-amylase with an IC50 value of 14.37μg/ml and α-glucosidase with an IC50 value of 26.73 μg/ml, highlighting its potential as an anti-diabetic agent. Then, EPS showed bactericidal properties with MBC/MIC≤2 against both G+ve and G-ve bacteria, Staphylococcus aureus , Enterococcus faecalis (MIC=3.9μg/ml), Salmonella typhi, and Helicobacter pylori.Conclusions: The marine EPSR9 exhibited considerable potential for pharmaceutical applications as a multi-bioactive microbial metabolite. Its in vivo potency and mechanisms of action warrant further investigation.

Ventilator weaning is a process of discontinuing mechanical ventilation and transitioning patients to independent breathing after a period of mechanical support. Weaning outcomes among the critically ill in intensive care units (ICUs) vary significantly among individuals, leading to considerable variation in healthcare costs, length of hospital stay, morbidity and mortality. Addressing psychosocial aspects of care can improve weaning outcomes. This study aimed to determine the effect of psychosocial factors (social support, family/significant other support, ability to communicate) on weaning outcome within intensive care patients. This research hypothesized that psychological and social factors play a role in determining ventilator weaning outcomes among ICU patients. This study used a longitudinal, retrospective research design to analyze positive and negative psychosocial predictors of ventilator weaning outcomes. Data collection methods include interviews and questionnaires with patients and their families, as well as clinical data from the patient's medical records. presence of anxiety, depression, and hallucinations, have a negative relationship with weaning outcomes regarding a patient's psychological characteristics (r_s = -0.207, -0.163, -0.158), while communication with a patient during mechanical ventilation have a positive relationship with weaning outcomes regarding a patient's psychological characteristics (r_s = 0.152; p ≤ 0.05). Moreover patients who have fear during weaning trials, feeling neglected, and feeling insecurity have a negative relationship with weaning outcomes while gaining family support during mechanical ventilation have a positive relationship with weaning outcomes (rs = 0.144; p ≤ 0.05).Significance of results, the findings suggests that psychosocial factors, such as anxiety, depression, patient's perception of their illness, motivation to wean, and family involvement can influence the success of ventilator weaning among patients in ICUs.
