The objective of our study was to clarify the impact of adverse events associated with the initial course of outpatient chemotherapy on the quality of life of breast cancer patients. We conducted a survey to assess the quality of life in 48 breast cancer patients before and after receiving their first course of outpatient chemotherapy at Gifu Municipal Hospital. Patients completed the European Quality of Life 5 Dimensions and Quality of Life Questionnaire for Cancer Patients Treated with Anticancer Drugs before and after 1 course of outpatient chemotherapy. European Quality of Life 5 Dimensions utility value and Quality of Life Questionnaire for Cancer Patients Treated with Anticancer Drugs total score decreased significantly after chemotherapy (p<0.001 and p = 0.018, respectively). The mean scores for the activity, physical condition, and psychological condition subscales of the Quality of Life Questionnaire for Cancer Patients Treated with Anticancer Drugs decreased significantly after chemotherapy (p = 0.003, p<0.001, and p = 0.032, respectively), whereas the social relationships score increased significantly (p<0.001). Furthermore, in the evaluation of quality of life according to individual adverse events, the decrease in quality of life after chemotherapy in terms of the European Quality of Life 5 Dimensions utility value and the Quality of Life Questionnaire for Cancer Patients Treated with Anticancer Drugs total score was greater in anorexic patients than in non-anorexic patients (p = 0.009 and p<0.001, respectively). This suggests that anorexia greatly reduces quality of life. Our findings reveal that anticancer drug-related adverse events, particularly anorexia, reduce overall quality of life following the first course of outpatient chemotherapy in current breast cancer patients. These findings are extremely useful and important in understanding the impact of anticancer drug-related adverse events on quality of life.

The authors previously reported that an extract from Zingiber officinale, traditionally eaten along with raw fish and used in traditional Chinese medicine, effectively destroyed Anisakis larvae in vitro. In this study, we analyzed the effective components of ginger rhizomes. Methanol extracts were fractionated after first being treated with HCl at pH 3, then with NaHCO3 at pH 10, and, finally, with NaOH at pH 13 (fraction 1). In general, this fraction is rich in neutral substances. [6]-Shogaol and [6]-gingerol, known neutral components of ginger rhizomes, were detected using gas chromatography and were found to be the most prevalent components in the fraction, occurring in quantities that resulted in a dose-dependent killing efficacy. Authentic [6]-shogaol and [6]-gingerol could kill Anisakis larvae at a minimal effective dose of 62.5 and 250 micrograms/ml, respectively. However, the concentration of [6]-gingerol in fraction 1 was greater than 20 times that of [6]-shogaol, making the former the most active component in the fraction. Furthermore, synergistic effects between [6]-gingerol and a small amount of [6]-shogaol were observed. Pyrantel pamoate, an available antinematodal drug, had no lethal effect, even at a concentration of 1 mg/ml. In saline solution containing [6]-shogaol (62.5 micrograms/ml), greater than 90% of larvae lost spontaneous movement within 4 h and were destroyed completely within 16 h. Microscopical examinations showed destruction of the digestive tract and disturbances of culticulae.

The results indicated that the presence of hyponatremia or hypokalemia increases the risk of falls.

BackgroundIn recent years, cancer chemotherapy is being conducted at outpatient clinics, wherein pharmacists are involved with patient guidance and management of adverse events as experts in medication therapy. Therefore, we clarified the influence of interventions by pharmacists during counseling of patients with cancer on patients’ quality of life.MethodsTo determine this influence, we conducted a survey to assess the quality of life of 39 patients with breast cancer who underwent their initial course of outpatient cancer chemotherapy at Gifu Municipal Hospital. A quality of life survey was conducted before the 1st, 2nd, and 3rd courses of treatment and was based on a method obtained from a survey paper entitled, “Quality of Life Questionnaire for Cancer Patients Treated with Anticancer Drugs.”ResultsTwenty patients were assigned to the intervention group, which received pharmacist counseling, and nineteen patients were assigned to the non-intervention group, which received no pharmacist counseling. Both groups were compared immediately before the 1st course and 2nd course. Regarding the subscale of social relationships, a significant difference was observed for malaise (p = 0.043), with the non-intervention group experiencing them to a greater degree than the intervention group. Regarding the change between immediately before the 1st course and the 3rd course, a significant difference was observed in the subscale of social relationships for nausea (p = 0.017), with the non-intervention group experiencing it to a greater degree than the intervention group.ConclusionsThe results suggest that receiving pharmacists’ guidance on adverse events and individually adjusted prescriptions tailored to address the occurrence of adverse events improved the treatment environment and enhanced the quality of life in the intervention group. These findings are beneficial in maintaining patients’ quality of life during cancer treatment.Trial registrationNo. UMIN000027171, Registration date: Apr 27, 2017. Retrospectively registered.
