Background: It is important for medical staffs to understand the state of stress of patients with cancer. The authors investigated stress assessment in patients with lung cancer undergoing chemotherapy. Materials and Method: Salivary cortisol and α-amylase were measured as stress markers before and after chemotherapy in 10 patients. Emotional status was assessed using the Profile of Mood States (POMS) questionnaire, and Quality of Life (QOL) was assessed using the Functional Assessment of Cancer Therapy-Lung (FACT-L) questionnaire. Results: No significant differences were found between the before and after chemotherapy in salivary levels of cortisol or α-amylase, the POMS and QOL scores. The salivary cortisol levels correlated with the POMS subscales of anger-hostility, and confusion. A negative correlation was observed between the salivary cortisol level and the QOL full score. The FACT-L full score correlated with the POMS subscales of depression-dejection, fatigue, and confusion. Conclusions: Measurements of salivary stress markers are noninvasive and may be useful for assessing the stress state of the patient

Objective: As it is important for medical staff to understand the stress state of patients with cancer, this study investigated the stress state in patients with lung cancer undergoing chemotherapy using salivary biomarkers and questionnaires. Materials and Methods: The subjects included 19 men and 9 women, with a mean age of 66.1 ± 7.1 years who received chemotherapy for lung cancer. Salivary samples of the participants were collected before and the 7 day after chemotherapy. Simultaneously, they completed the POMS (profile of mood states) and QOL (quality of life) questionnaires. The salivary cortisol and secretory IgA as stress markers were measured by enzyme immunoassay. Results: The salivary secretory IgA level was significantly higher at the 7th day after chemotherapy than before chemotherapy (p < 0.05), although the salivary cortisol level did not change. The tension-anxiety score, which is one of POMS subclasses, and total mood disturbance score were lower at day 7 of chemotherapy than before chemotherapy (p < 0.05), although no correlations were observed between POMS scores and salivary markers. However, a negative correlation was observed between the salivary cortisol level and the QOL full score (r= -0.411, p < 0.05). Conclusion: Measurement of salivary stress markers is noninvasive and may be useful for assessing the stress state of the patients

BACKGROUND High levels of physical activity improve the prognosis and quality of life (QOL) for patients undergoing hemodialysis (HD). The aims of this study were to measure physical activity using a pedometer and to explain the relationship between physical activity and clinical outcomes in HD patients. METHODS The study population comprised 38 patients (17 men and 21 women; mean age: 56.1 years; range, 41–69 years) who underwent HD 3 days/week. Physical activity was measured with a pedometer. The relationships between the clinical data and levels of physical activity were examined. RESULTS The mean number of steps taken per day for 1 week was 4,157.4 ± 2,068.1, and the mean value for all‐consumption calories per day for 1 week was 1,623.0 ± 240.5 kcal. The mean daily value for all‐consumption calories showed positive correlations with basal metabolic calorie and serum creatinine levels, as well as the Physical Functioning score in the Kidney Disease Quality of Life‐Short Form instrument (KDQOL‐SF), whereas it showed negative correlations with the levels of total cholesterol and low‐density lipoprotein (LDL) cholesterol and the cardiothoracic ratio. The mean calorie consumption by action, subtracting basic metabolism calories from all‐consumption calories, also showed positive correlations with the number of steps and the Physical Functioning score in the KDQOL‐SF, while it showed negative correlations with the total cholesterol and LDL cholesterol levels. CONCLUSIONS The parameter of all‐consumption calories per day, measured with a pedometer, is useful for evaluating the levels of physical activity of HD patients and for formulating exercise recommendations.
