This study aimed to clarify the effects of carbohydrate mouth rinse on exercise performance. We examined the effect of mouth rinse on fatigability. Thirty healthy male college students completed three trials with non mouth rinse (CON), mouth rinse intervention of 6% glucose (GMR), and artificial sweetener (PLA). Handgrip exercise was performed as a fatigue task. The subjects performed a 10-seconds maximal voluntary contraction (MVC) followed by a 40% MVC rhythmic grasping movement for 14 per minutes, followed by a 4-seconds rest. This set of exercises was performed for a total of ten sets. Mouth rinse was performed from the 5th set to the 10th set. The subjects were divided into three groups: L, M, and S, according to the degree of decrease in MVC due to fatigue in CON. The effect was evaluated using the rate of change in MVC after the mouth rinse. The evaluation was performed for each trail and group. In the L group, mouth rinse significantly improved the rate of change of MVC compared with the other trials (GMR vs. CON: P = 0.002; PLA vs. CON: P = 0.042). A significant trend was observed in the M (GMR vs. CON: P = 0.062), but not in the S. In conclusion, the effects of mouth rinse differed depending on fatigability in isometric hand grip performance, with mouth rinse inhibiting the decrease of motor fatigue. In addition, it was suggested that the sweetness of carbohydrates may have an effect on mouth rinse.

Objective: To clarify factors related to emotional instability in spouses of cancer patients receiving palliative chemotherapy. Methods: Semi-structured interviews were conducted with spouses of cancer patients receiving palliative chemotherapy, and the obtained data were qualitatively and inductively analyzed. Results: Through analysis, 9 related factors were identified: “realizing the severity of the situation when receiving an explanation of the pathological condition”, “an unclear prognosis”, “fear of losing any treatments”, “being pressed for treatment-related decision-making”, “increased daily burdens by the care”, “collapse the visions of the family future”, “communication with medical professionals”,“candid dialogues with the patient”, and “relationships with others”. Conclusion: It may be important for nurses to help families of cancer patients realistically manage their situation without excessive confusion, even when they experience emotional instability, and spend meaningful time with patients as an outcome of treatment, with an understanding of these related factors on such emotional instability.
