Workload, Fatigue, and Cognitive Performance in University Hospital Nurses: A Cross-Sectional Study
Get PDFIntroduction: As the largest workforce in the healthcare industry, nurses are essential to maintaining patient safety. Personal and environmental factors, including high demands, irregular work hours, and large workloads, make nurses vulnerable to fatigue.Methods: The study involved 60 participants using several tools for data collection, including the NASA Task Load Index (NASA-TLX) to assess workload, the Swedish Occupational Fatigue Inventory (SOFI) to measured fatigue, heart rate variability (HRV) measurements to evaluated autonomic nervous system activity, electroencephalogram (EEG) analyzed for cognitive functions, and the Psychomotor Vigilance Test (PVT) to assessed cognitive performance.Results: The findings revealed that the nurses experienced high subjective workloads, particularly related to mental, physical, and temporal demands. Fatigue, especially in terms of energy depletion and sleepiness, was significantly reported. HRV data indicated a shift toward parasympathetic dominance after each shift, while EEG results showed decreased theta and alpha wave activity, suggesting increased fatigue. The PVT results showed slower reaction times and more lapses in performance, especially after night shifts, indicating cognitive impairment due to fatigue.Conclusions: These results highlight the considerable impact of high workloads, shift work, and fatigue on the health and performance of nurses. The study suggests that healthcare institutions should implement strategies to reduce workload, manage fatigue, and improve recovery to maintain optimal cognitive performance and overall well-being of nursing staff. These findings can inform policies aimed at improving working conditions and ensuring better care delivery in hospital settings

The Effect of Leadership Antecedents on School Leaders’ Decision-Making: The Mediating Role of Strategic Thinking
Get PDFIntroduction: Educational leadership today faces mounting complexity, requiring school leaders to make rapid yet well-reasoned decisions that influence institutional success. Existing leadership development programmes, such as the National Professional Qualification for Educational Leadership (NPQEL), emphasise strategic thinking and performance; however, the specific psychological and behavioural traits that underpin decision-making remain underexplored. This study aims to investigate how self-efficacy (a psychological trait) and ambidextrous leadership (a behavioural trait) influence school leaders’ decision-making, with strategic thinking examined as a mediating cognitive process. Grounded in Social Cognitive Theory and Trait Theory, the research addresses a key gap in understanding how internal beliefs and adaptive leadership behaviours translate into decision-making competence through strategic cognition. Methods: A quantitative research design was employed using Partial Least Squares Structural Equation Modelling (PLS-SEM). The sample comprised 275 school leaders across Malaysia who completed the NPQEL programme between 2018 and 2020. Data were analysed to test both direct effects and mediating pathways within a hypothesised structural model. Results: The findings indicate that both self-efficacy and ambidextrous leadership significantly predict decision-making capability. Importantly, strategic thinking was found to partially mediate these relationships, suggesting that school leaders with greater emotional and behavioural adaptability leverage strategic cognition to make more effective decisions. These results reinforce the necessity for leadership programmes to move beyond technical training by incorporating strategies that foster psychological resilience and strategic cognitive development. Conclusion: The study contributes to the theoretical advancement of educational leadership by integrating emotional, behavioural, and cognitive dimensions into a unified model of decision-making. Practically, it offers evidence-based insights for policymakers and educational institutions to enhance leadership preparation for complexity, ambiguity, and outcome-driven environments
A Literature Review on ARV Adherence, CD4 Count, and Menstrual Disorders in HIV-Infected Women
Get PDFHIV/AIDS remains a critical global health challenge, with women of reproductive age constituting a significant proportion of the affected population. The interplay between antiretroviral therapy (ART) regimens, medication adherence, psychological stress levels, CD4 cell counts, and menstrual health is complex and multifaceted. This systematic review synthesizes findings from eight studies published between 2015 and 2025, exploring how different ART regimens, particularly Dolutegravir-based (DTG) versus Efavirenz-based (EFV) affect immunological and reproductive outcomes in women living with HIV. The review highlights that regimen type, adherence to medication, and psychological stress significantly mediate CD4 count fluctuations and menstrual disturbances, including irregular cycles and amenorrhea. Furthermore, CD4 count acts as a mediating variable in the relationship between ART, stress, and menstrual health. Evidence suggests that DTG regimens are associated with better immune profiles and fewer reproductive side effects, whereas stress and poor adherence exacerbate immunosuppression and reproductive dysfunction. These findings underscore the need for integrated, gender-sensitive healthcare approaches that address immunological, psychological, and reproductive health in women with HIV
