[The relationship between depression, perceived stress, fatigue and anger in clinical nurses].

PURPOSE: The purpose of this study was to identify the relationship between depression, perceived stress, fatigue and anger in clinical nurses. METHOD: A descriptive survey was conducted using a convenient sample. Data was collected by questionnaires from four hundred clinical nurses who worked at a university hospital. Radloff's CES-D for depression, Cohen, Kamarck & Mermelstein's Perceived Stress Scale, VAS for Fatigue, and Spielberger's STAXI for anger were used. The data was analyzed using the pearson correlation coefficient, students' t-test, ANOVA, and stepwise multiple regression with SPSS/WIN 12.0. RESULT: The depression of clinical nurses showed a significantly positive correlation to perceived stress(r=.360, p=.000), mental fatigue(r=.471, p=.000), physical fatigue(r=.350, p=.000), trait anger(r=.370, p=.000), anger-in expression(r=.231, p=.000), and anger-control expression(r=.120, p=.016). There was a negative correlation between depression and age(r=-.146, p=.003). The mean score of depression of nurses, 26, was a very high score and 40.8% of clinical nurses were included in a depression group. The main significant predictors influencing depression of clinical nurses were mental fatigue, trait anger, perceived stress, anger-in expression, and state anger, which explained about 32.7%. CONCLUSION: These results indicate that clinical nurses with a high degree of perceived stress, mental fatigue and anger-in expression are likely to be depressed.

The impact of a stage-matched intervention to promote exercise behavior in participants with type 2 diabetes.

This study was designed to develop and evaluate a stage-matched intervention (SMI) in Korean participants with type 2 Diabetes. The SMI was based on main constructs derived from the Transtheoretical Model match to the individual's stages of readiness for exercise behavior. The SMI was developed according to the results of the content validity tested by an expert group (n = 9). A control group pre- and post-test design was used for evaluating the impact of the SMI: the intervention group (n = 22) participated in the SMI for 3 months, while the control group (n = 23) received usual educational advice. The intervention group, compared to the control group, showed significant improvements in stages of change for exercise behavior (p < 0.001), physical activity levels (p < 0.001), and reductions in FBS (p < 0.05) and HbA(1)c (p < 0.05). This study yielded evidence for the beneficial impact of the SMI in participants with type 2 Diabetes.

Sex differences in immune responses and immune reactivity to stress in adolescents.

The immune system is the body's major defense mechanism against disease. However, psychosocial factors, such as stress, can modulate various immune responses. Although they have been examined in adult humans and other animals, sex differences in immune responses and immune reactivity to stress have rarely been examined in adolescents, particularly comparing healthy and asthmatic adolescents. In 151 healthy and asthmatic high school adolescents (91 females and 60 males), natural killer cell (NK) cytotoxicity, polymorphonuclear leukocyte (PMN) superoxide release, lymphocyte proliferative responses, and CD subsets were measured twice: once during mid-semester and again during final examinations. There was little difference in these measures between healthy and asthmatic adolescents. Similarly, only sex difference was noted in NK cytotoxicity at a 25:1 effector-to-target cell ratio, with males showing significantly higher responses than females. For PMN superoxide release, females significantly increased their responses during final examinations, whereas males demonstrated no changes. For lymphocyte proliferative responses, both females and males increased their responses during final examinations, but the magnitude of increase was much greater in males. Furthermore, racial comparisons indicated that African American adolescents (n = 16), as compared with Caucasian adolescents (n = 128), had significantly higher responses in PMN superoxide release to N-Formyl-Met-Leu-Phe (FMLP) activation during mid-semester and lymphocyte proliferative responses at both time points. Nevertheless, the overall findings indicate limited differences in immune responses and immune reactivity to stress in adolescents between males and females, healthy and asthmatic adolescents, and Caucasians and African Americans. However, further investigations with larger samples are warranted.

Development and validation of a computerized exercise intervention program for patients with type 2 diabetes mellitus in Korea.

This study was designed to develop and validate a computerized exercise intervention program using the transtheoretical model (TTM) for Korean patients with type 2 diabetes mellitus (DM). This computerized program was web-based and developed by designing a flow chart. An expert group (n=24), who validated the content of the computerized program, produced a mean score for the evaluation scale of 4.25 (SD.56). Of the patients (n=28) with type 2 DM who participated in clinical validity testing of the program, the mean score for the satisfaction scale was 4.82 (SD.12). In the validation of the program, significant differences between baseline and after-intervention were observed in the stage of readiness for exercise (Z=-3.78, p < 0.001), physical activity (Z=-2.33, p < 0.05), blood glucose profiles [FBS (Z=-2.84, p < 0.01), pc 2 hr. glucose (Z=-2.33, p < 0.05), HbA1c (Z=-2.77, p < 0.01)], and VO2max (Z=-2.52, p < 0.01). The study confirmed that the computerized program could be used to construct a database and continue to provide follow-up intervention for patients in all stages.

Cardiopulmonary responses and adherence to exercise in women newly diagnosed with breast cancer undergoing adjuvant therapy.

Cardiopulmonary responses to an 8-week moderate-intensity aerobic exercise intervention and adherence to exercise during and after intervention were assessed in 41 women newly diagnosed with breast cancer undergoing adjuvant therapy. The intervention was primarily aimed at minimizing deconditioning. Women were randomly assigned to the intervention or control group, completed graded exercise tests before and after intervention, and encouraged to continue their exercise postintervention. Over time, only the intervention group showed significant decreases in resting heart rate, resting systolic blood pressure (SBP), P <.05 each, and maximum SBP, P <.02, and an increase in VO2 peak, P <.001, although resting SBP was higher in the intervention group at both timepoints, P <.05. The adherence rate to 8-week exercise intervention was 78.3% with average weekly attendance of 2.4 sessions and 42.7 minutes (27.8 minutes within target heart rate) exercise per session. Overall physical activity levels over 16 weeks postintervention did not differ between 2 groups. However, the within-group analysis indicated that only the intervention group showed a significant increase in voluntary activity, P < .02, and energy expenditure, P < .02, and a decrease in sedentary activity, P < .02. These findings indicate that moderate-intensity aerobic exercise is beneficial in reducing deconditioning of cardiopulmonary responses in newly diagnosed breast cancer women undergoing adjuvant therapy.

Utility of a Web-based intervention for individuals with type 2 diabetes: the impact on physical activity levels and glycemic control.

Despite the numerous benefits of physical activity for patients with diabetes, most healthcare providers in busy clinical settings rarely find time to counsel their patients about it. A Web-based program for healthcare providers can be used as an effective counseling tool, when strategies are outlined for specific stages of readiness for physical activity. Seventy-three adults with type 2 diabetes were randomly assigned to Web-based intervention, printed-material intervention, or usual care. After 12 weeks, the effects of the interventions on physical activity, fasting blood sugar, and glycosylated hemoglobin were evaluated. Both Web-based and printed material intervention, compared with usual care, were effective in increasing physical activity (P < .001) and decreasing fasting blood sugar (P<.01) and glycosylated hemoglobin (P < .01). Post hoc analysis for change scores indicated significant differences between Web-based intervention and usual care and between printed material intervention and usual care, but not between web-based and printed material intervention. The findings of this study support the value of Web-based and printed material interventions in healthcare counseling. With increasing Web access, the effectiveness of Web-based programs offered directly to patients needs to be tested.
