RESUMEN
An 82-year-old woman visited our hospital complaining of a rapidly growing hemorrhagic mass with ulceration of the right breast. A CT scan revealed a circumscribed, lobulated mass of approximately 14 cm diameter, with coarse calcifications, which had invaded the skin and major pectoral muscle and with metastasis in the both lungs. She underwent a total mastectomy with major pectoral mastectomy. The pathological findings were spindle cell carcinoma admixed with chondroid metaplasia and an osteoid-like appearance; therefore, metaplastic breast cancer was diagnosed. Biweekly drip infusion of immune checkpoints inhibitor were administered as immunotherapy, which yielded a complete response of lung matastasis. Administration of monthly immune checkpoints inhibitor resulted in no recurrence for 3 years after the operation. Accumulation of further similar cases and development of a novel effective treatment are desired.

PURPOSE: Low physical function can be effectively improved via intradialytic exercise. However, the association between the effects of intradialytic exercise on physical function and malnutrition severity has not been studied extensively. This study aimed to investigate the impact of nutritional status severity on physical function in patients undergoing hemodialysis with low physical function to whom intradialytic exercise was prescribed. METHODS: The participants were patients with decreased mobility [walking speed < 1.0 m/s and/or Short Physical Performance Battery (SPPB) < 12] who had been undergoing hemodialysis thrice a week for 6 months and performing intradialytic exercise program. Patients were divided into groups based on the Geriatric Nutritional Risk Index (GNRI) [Non-malnutrition group (GNRI > 98), Gentle/slim malnutrition group (GNRI ≤ 98, GNRI ≥ 92), Mild malnutrition group (GNRI < 92, GNRI ≥ 82), Severe malnutrition group (GNRI < 82)]. The primary outcomes were Grip strength, isometric knee extension strength (IKES), SPPB, and 10-m walking speed measured at baseline and at 6 months. Statistical analyses were performed using a linear mixed-effects model with the intention-to-treat analysis, including within-group analysis and between-group comparison. RESULTS: A total of 805 participants were included in the study. Within-group comparisons showed significantly improved IKES, 10-m walking speed, and SPPB improved, except in the Severe malnutrition group. Grip strength significantly improved in the Gentle/slim and mild malnutrition groups. Between-group comparison with controls showed that the improvement in Grip strength was significantly bigger in the Gentle/slim malnutrition group [0.98 (0.15 to 1.82) kg] than in the non-malnutrition group. However, IKES in the Severe malnutrition group [- 5.14 (- 9.18 to - 1.10) %] less significantly improve than that in the non-malnutrition group. No significant differences were found in the other indices. CONCLUSION: In patients with severe malnutrition, the changes in IKES scores resulting from Intradialytic exercise were significantly smaller than those observed in non-malnourished patients. Therefore, it is necessary to initiate suitable nutritional and exercise therapy based on the severity of malnutrition.

PURPOSE: Exercise therapy is a crucial intervention for improving health-related quality of life (HRQOL) in patients undergoing haemodialysis. However, factors that improve HRQOL by improving physical function and dialysis-related symptoms remain unknown. This study aimed to examine the physical function parameters and dialysis-related symptoms that improve HRQOL following intradialytic exercise. METHODS: This multicentre cohort study included 596 patients who participated in an intradialytic exercise program three times per week for a period of 6 months, which comprised of stretching and resistance training. EuroQol 5 dimensions 5-level (EQ5D-5L), grip strength, isometric knee extension strength, 10-m walking speed, Short Physical Performance Battery (SPPB), and improvement in dialysis-related symptoms were measured at the baseline and post-intervention. A linear mixed model was used to analyse the effects of improved physical function and dialysis-related symptoms on improvements in EQ5D-5L. RESULTS: As a physical function index affecting ΔEQ5D-5L, only SPPB showed a significant increase in ΔEQ5D-5L compared with the non-improved group [difference in ΔEQ5D-5L, 0.05 (0.004 to 0.092) point; p < 0.05]). In addition, dialysis-related symptoms with Improved physical conditions [difference in ΔEQ5D-5L, 0.07 (0.02 to 0.13) point] and an Extended walking distance [difference in ΔEQ5D-5L was 0.07 (0.01 to 0.12) point] significantly influenced ΔEQ5D-5L (p < 0.05, both). CONCLUSIONS: The improvements observed in the SPPB scores and self-percieved physical fitness and ambulation range, attributable to intradialytic exercise, may potentially improve HRQOL.
