Driven by the need for remote learning, the COVID-19 pandemic led to the rise of use of videoconferencing tools. Scholars began noticing an emerging phenomenon of feeling tired and exhausted during virtual meetings. This study determined the predictors of videoconference or Zoom fatigue among nursing students in a large, private, non-sectarian university in the Philippines. This cross-sectional online survey involves 597 nursing students in the Philippines using the Zoom Exhaustion and Fatigue Scale. Multiple linear regression analysis was used to examine predictors of videoconference fatigue. Results indicated that nursing students experienced high levels of videoconference fatigue. Gender, self-reported academic performance, Internet connection stability, attitude toward videoconferencing, frequency, and duration of videoconferences predicted videoconference fatigue. The regression model explained 25.3% of the variances of the videoconference fatigue. Videoconference fatigue is relatively prevalent and may be taking its toll on nursing students. Developing strategic interventions that can protect or mitigate the impact of fatigue during virtual meetings is needed.

Purpose: The purpose of this longitudinal prospective study was to assess changes in fatigue and quality of life for a 6-week course of radiotherapy. Method: A descriptive and longitudinal design was used to this study. Twenty-three subjects receiving radiotherapy from a radiotherapy clinic of a general hospital completed the questionnaires. Fatigue was measured using Lee's scale(1999) and quality of life using Yang's scale(2002) weekly for 6 weeks. Result: Fatigue significantly increased(F=6.043, p=.000), and quality of life significantly decreased (F=3.938, p=.003) and physical symptoms also significantly increased(F=2.432, p=.039) during a 6-week radiotherapy. Multiple regression analysis revealed that fatigue at the first week and physical symptoms at the 6th week were the significant affecting variables(60.1% of the variance) on fatigue. And 63.2% of the variance in quality of life was explained by quality of life and fatigue at the first week and body weight change for 6 weeks radiotherapy. Conclusion: Based on these results, the fatigue and quality of life at the beginning time of radiotherapy have a lasting impact throughout the course of treatment. It suggests that nurses provide patients with information about the occurrence of fatigue during radiotherapy and the practical methods of intervening physical symptoms.

Purpose: The purpose of this study was to describe the impact of fatigue and distress on self-efficacy among breast cancer survivors and to provide a base for development of nursing intervention strategy to improve self-efficacy. Methods: A descriptive research design was used. The subjects were 158 patients who were either being treated or were receiving follow-up care at a university breast center in D City from May 30 to August 30, 2014. Structured questionnaires, Revised Piper Fatigue Scale, Distress Thermometer, and Self-Efficacy Scale for Self-Management of Breast Cancer were used to measure fatigue, distress, and self-efficacy. Data were analyzed using t-test, ANOVA, Pearson's correlation coefficients, and multiple regressions. Results: The mean scores of fatigue, distress, and self-efficacy were 3.83, 4.31, and 3.77, respectively. There were significant differences among participants in terms of educational background, current treatment methods, perceived health status, economic burden for fatigue and perceived health status for distress. Self-efficacy was impacted by age, educational background, marital status, average monthly income, perceived health status, and medical expenses. Fatigue, age, and the burden on medical expense had the most impact on self-efficacy, accounting for 17% of the variance. Conclusion: Fatigue should be managed to improve self-efficacy of breast cancer survivors. Therefore, nursing programs designed to decrease fatigue may be helpful.

Purpose: This study aimed to identify the prevalence of fatigue and its associated factors leading to the fatigue among Korean commercial airline pilots. Methods: An anonymous, web-based questionnaire collecting data on sleep related characteristics was completed by airline pilots. The final 1,029 samples of completed questionnaires were analyzed. The association of the risk factors with fatigue was determined using logistic regression analysis. Results: The prevalence of fatigue was 60% (Fatigue Severity Scale index≥3.2), disturbed sleep 28% (Pittsburgh Sleep Quality Index≥9), daytime sleepiness 17% (Epworth Sleepiness Scale≥10), and sleep apnea (Berlin Questionnaire≥2) 11%. The fully adjusted logistic regression showed that quality of life (odds ratio [OR]=0.16, confidence interval [CI]=0.11-0.24), daytime sleepiness (OR=1.26, CI=1.18-1.34), sleep quality (OR=1.44, CI=1.29-1.61), mental workload (OR=1.10, CI=1.05-1.14), vigorous physical activity (OR=0.82, CI=0.72-0.92), late starts (OR=1.25, CI=1.06-1.46) and average weekly flying hours (OR=1.02, CI=1.00-1.03) were associated with higher levels of fatigue. Conclusion: Lower quality of life, disturbed sleep, more subjective sleepiness, shorter sleep duration, higher mental workload, less vigorous physical activity, frequent late starts, and longer flying hour were shown to be risk factors for fatigue in airline pilots. These findings should be taken into account in the development of sleep and fatigue countermeasures for airline pilots.

Purpose: Reported insomnia and decreased sleep quality are common among older adults. The purpose of this study was to identify factors contributing to insomnia and decreased sleep quality among elderly persons living within a community. The data will be verified with Actigraph which is a non-invasive measurement of rest/activity cycles. Methods: 137 participants over 65 years old were recruited from a senior welfare center. Their mean age was $74.07{\pm}5.18years$ old and majority was women (69.3%). The quality and quantity of nighttime sleep were assessed using Varren-synder-Halper Sleep Scale and a sleep log. Depression and fatigue were assessed using Geriatric Depression Scale Short Form and Fatigue Severity Scale, respectively. Pain was assessed using 11-point Numeric rating scale. An actigraph was used to verify the self-reported sleep. Results: Ninety-two participants (67.2%) reported insomnia. Sixty-eight subjects (49.6%) reported good sleep. Of the participants, 56.2% reported depression and 33.6% reported fatigue. In logistic regression, depression was related to insomnia (OR=3.09, p=.003). Sleep quality was related to depression (OR=2.13, p=.045) and fatigue (OR=2.24, p=.044). The data from the Sleep logs correlated with data obtained from the actigraph. Conclusion: Depression significantly influenced insomnia and sleep quality whereas fatigue only influenced sleep quality. Thus, depression and fatigue should be closely monitored among elderly persons with sleep disturbances.

Purpose: This study aimed to evaluate nutritional status and fatigue, and to identify the relationship between nutritional status and fatigue in gynecological cancer patients receiving chemotherapy. Methods: Participants were 106 outpatients who had uterine, ovary, or breast cancer and a descriptive cross-sectional design was used. Nutritional indicators including biochemical and anthropometric measures, the Subjective Global Assessment (SGA) scale, and the Piper's Revised Fatigue Scale were completed. Results: About thirty-nine percent of the patients were malnourished based on the SGA. Serum hemoglobin and total lymphocyte levels were less than the normal ranges, although anthropometrics were normal. The women experienced moderate fatigue with a mean score of $5.84{\pm}2.00$. Nutritional status was significantly different by age, education, employment status, and monthly income. The women also had different nutritional status and fatigue depending on the type of cancer and chemotherapy. Fatigue was significantly related to SGA scores, serum hemoglobin, triceps skinfold thickness and mid-arm muscle circumference. Conclusion: The results of this study highlight an urgent need to provide adequate nutritional support and fatigue management with individualized strategies for gynecological cancer patients on chemotherapy.

Purpose: The purpose of this study was to identify the relationship between energy intake and fatigue in cancer patients receiving chemotherapy. Methods: A total of 106 subjects had participated in this study. Data were collected at a university hospital in D city from September 1st to November 10th, 2010. Energy intake including carbohydrates, protein and fat was measured by scale and analyzed using Can Pro 3.0 program. Fatigue level was measured by the Revised Piper Fatigue Scale. Data were analyzed using descriptive analysis, t-test, ANOVA and Pearson correlation coefficient with SPSS/WIN 15.0. Results: The mean calorie intake during chemotherapy was $906.53{\pm}201.28Kcal/day$ which was 45.3% of the recommended daily calorie intake. The mean of protein intake level was $43.62{\pm}11.13g/day$, and it was low compared to the recommended daily protein intake. Calories, carbohydrates, and protein levels on 3rd day after chemotherapy were significantly lower than those of 2nd day after chemotherapy (p<.001). The fatigue level during chemotherapy was $5.77{\pm}0.77$ which was moderate level of fatigue. There was a significant negative interrelation between energy intake and fatigue. Conclusion: Theses results suggested that nursing approaches to encourage dietary intake may be helpful to reduce fatigue for cancer patients receiving chemotherapy.

Purpose: This study aimed to investigate sleep, fatigue, and the level of health promoting behaviors in Korean army soldiers. The factors influencing on health promoting behaviors of soldiers were also identified. Methods: A cross-sectional descriptive survey design was used. Data was collected from 269 soldiers in four military units of Korea in July 2015. Verran and Snyder-Halpern Sleep Scale, Fatigue Severity Scale, and Health Promoting Lifestyle Profile-II were used. Results: The health promoting behaviors were significantly different by perceived health status (p<.001) and presence of fatigue (p<.001). There were significant correlations between quality of sleep, fatigue, and health promoting behaviors of the subjects. In a multiple linear regression analysis, the level of health promoting behaviors were lower in the subjects with high level of fatigue (p<.001) and with fair perceived health status (p=.003). Conclusion: In order to increase health promoting behaviors of soldiers, it takes into account of soldiers' fatigue and perceived health status. Environmental arrangement for soldiers for the break time is needed urgently to decrease their fatigue as well as to improve their sleep quality.
