Is Phase Angle Useful in Screening for Sarcopenia in Patients with Hematologic Malignancies?

The purposes of this study were to investigate the relationship between sarcopenia and phase angle (PhA), and to examine whether PhA cutoff values can be used to identify sarcopenia in patients with hematologic malignancies. The study population comprised 108 patients with hematologic malignancies who were admitted for chemotherapy, and were undergoing rehabilitation for exercise therapy. The diagnostic criteria for sarcopenia were determined according to the Asian Working Group for Sarcopenia 2019. Muscle strength, endurance, and body composition (including PhA), were assessed. Logistic regression and receiver operating characteristic (ROC) curve analyses were performed to investigate associations between sarcopenia and PhA, and to determine cutoff values. Sarcopenia was found in 17.6% of the participants. PhA was significantly associated with sarcopenia (p < 0.01). The areas under the curve were 0.84 for the males and 0.87 for the females, and the cutoff values were 4.75° for the males (sensitivity 69%, specificity 83%) and 3.95° for the females (sensitivity 78%, specificity 85%). Our results suggest that PhA, which can be measured noninvasively, objectively, and rapidly, can be used as a screening tool for sarcopenia in patients with hematologic malignancies.

Impact of Sarcopenia on Outcome of Exercise Therapy in Older Non-Hodgkin Lymphoma Patients.

PURPOSE: The aim of this study was to investigate the effects of exercise therapy on physical function and quality of life (QOL) in older patients with non-Hodgkin lymphoma undergoing inpatient chemotherapy, including differences between patients with and without sarcopenia. METHODS: Thirty-one inpatients aged 70 years or older participated in this study. Grip and knee extensor strength, 6-minute walking test, body composition, nutritional status, fatigue and health-related QOL at admission and discharge were compared. In addition, the patients were classified into sarcopenic and non-sarcopenic groups, and a comparison between admission and discharge and 2-way ANOVA were performed. RESULTS: Overall, grip strength and skeletal muscle mass were significantly lower at discharge than at admission (P < .05); however, QOL significantly improved (P < .05). In the non-sarcopenia group, grip strength, right knee extension muscle strength, and skeletal muscle mass were all significantly lower at discharge than at admission (P < .05); however, this was not the case in the sarcopenia group. In terms of QOL, improvements were observed in different items in the non-sarcopenia and sarcopenia groups. There was a significant interaction between admission to discharge time period and sarcopenia regarding left grip strength, right knee extensor strength, and QOL. CONCLUSION: Exercise therapy is effective in improving QOL in older non-Hodgkin lymphoma patients undergoing inpatient chemotherapy. However, the effect of exercise therapy and optimal exercise load may differ between non-sarcopenia and sarcopenia patients. Therefore, it is necessary to consider exercise therapy in the future, taking into account the presence or absence of sarcopenia.

Balance Function Required for Bathing Independence in Patients with Stroke and Hip Fracture.

Objectives: Little attention has been paid to the relationship between balance function and bathing independence. This research aimed to determine the degree of balance function needed by patients with stroke and patients with hip fracture (hereinafter referred to as patients with stroke and hip fracture) to bathe independently. Methods: Retrospective data analysis was performed on 59 patients with hip fracture and 201 patients with stroke. Logistic regression was performed to determine whether bathing independence was associated with the Berg Balance Scale (BBS) in patients with stroke and hip fracture. A receiver operating characteristic curve was generated to calculate cutoff values. Results: The BBS was significantly associated with bathing independence in patients with stroke and hip fracture. The calculated BBS cutoff value was 48 points for those with stroke (sensitivity, 84.7%; specificity, 79.1%) and 43 points for those with hip fracture (sensitivity, 81.3%; specificity, 77.8%). Conclusions: Balance function was independently associated with bathing independence. The level of balance function required for bathing independence may be lower for patients with hip fracture than for those with stroke. This could be a simple and useful indicator for rehabilitation professionals to interpret BBS results when conducting bathing interventions.

The effect of combined risk factors on breast cancer-related lymphedema: a study using decision trees.

BACKGROUND: The effect of combined risk factors on breast cancer-related lymphedema (BCRL) development has not yet been investigated. This study aimed to determine the combination of risk factors associated with BCRL development in patients who underwent breast cancer resection, including axillary lymph node dissection (ALND). METHODS: The participants included 129 women who were diagnosed with early-stage breast cancer and underwent breast cancer resection in this retrospective observational study. We performed a decision tree analysis to detect the combination of risk factors associated with BCRL development using age, body mass index (BMI), surgical side, mastectomy, the extent of ALND, and adjuvant therapy (chemotherapy, hormone therapy, and radiation therapy). RESULTS: Of the 129 participants, 11 (8.5%) developed BCRL. Postoperative chemotherapy was the optimal variable selected to classify patients who developed BCRL and those who did not. In participants with postoperative chemotherapy, the extent of ALND was selected as the second layer of the decision tree. When ALND was at level 3, BMI was selected as the third layer. We found that BCRL incidence was 44.4% in individuals with a BMI of 23.0 or higher. CONCLUSIONS: The combination of postoperative chemotherapy, level 3 ALND, and BMI of 23.0 or higher may further increase the risk of developing BCRL. The decision tree model will enable the identification of patients with a high risk of developing BCRL, and thus, preventive intervention, careful monitoring, and early treatment will be possible.

Physical function, nutritional status, and quality of life before and after chemotherapy in patients with malignant lymphoma.

This study investigates the efficacy of and gender differences in exercise therapy in patients with malignant lymphoma undergoing chemotherapy. Twenty-six patients (13 men, 13 women) received physical therapy (based on the Borg Scale 13) during hospitalization. Physical function was measured using grip and knee extension strength, 6-minute walking distance, and body composition; nutritional status assessed via Mini Nutritional Assessment (MNA®); and serum albumin levels analyzed. Fatigue was evaluated using the Brief Fatigue Inventory, and health-related quality of life was assessed with the Medical Outcome Study 36-Item Short-Form Health Survey (SF-36v2). The analysis of all patients indicated that the right grip strength, skeletal muscle mass, skeletal muscle index, and leg muscle mass significantly decreased, whereas the serum albumin level, MNA® score, and scores of many items of the SF-36v2 significantly increased after chemotherapy. In a gender-specific analysis, only men showed significant declines in the skeletal muscle mass and skeletal muscle index, and improvement in the MNA® score after chemotherapy. In the SF-36v2, there were significant improvements in general health and physical component summary scores among men, and general health and mental component summary scores among women. Exercise therapy at a Borg Scale intensity of 13 may not prevent muscle mass decline in patients with malignant lymphoma, especially male patients. In addition, this study revealed that there is a gender difference in the effect of exercise therapy on quality of life. Thus, gender should be considered in exercise therapy for patients with malignant lymphoma.

Differences in the Relationships Between Muscle Strength, Muscle Mass, Balance Function, and Quality of Life for Middle-Aged and Older Breast Cancer Survivors.

PURPOSE: The purpose of this study was to investigate the differences in muscle strength, muscle mass, balance function, and quality of life (QOL) among middle-aged breast cancer survivors (BCSs) and older BCSs. METHODS: The study included 53 middle-aged (<65 years old) BCSs and 49 older (≥65 years old) BCSs. Muscle strength was evaluated via handgrip and knee extensor strength, and muscle mass was assessed using a body composition test. Balance function was assessed using the Timed Up and Go test and the body sway test. QOL was assessed using the Medical Outcome Study 36-item Short-Form Health Survey. RESULTS: The older BCSs had significantly lower right grip strength, right knee extension strength, and muscle mass (P < .05) than the middle-aged BCSs. In addition, the body sway test showed that older BCSs had a significant increase in the length of center of pressure compared to middle-aged BCSs (P < .05). Older BCSs showed significantly lower physical functioning subscales in QOL compared to middle-aged BCSs (P < .05). The associations among muscle strength, muscle mass and QOL were more significantly observed in the older BCSs (P < .05). Furthermore, a significant correlation between QOL and balance function was observed in the older BCSs, but not in the middle-aged BCSs (P < .05). CONCLUSION: There may be associations among muscle strength, muscle mass, balance and QOL in older BCSs, but not in middle-aged BCSs. We believe that the findings of this study will be relevant in the context of planning rehabilitation for older BCSs.

Relationship between Activities of Daily Living of Home-Based Rehabilitation Users and Caregiver Burden-Induced Depression: A Retrospective Study.

This study was aimed at determining the cutoff values of activities of daily living (ADL) and the combination of related factors associated with high caregiver burden that induces depression among caregivers. The study participants included 50 pairs of home-based rehabilitation users and their primary caregivers. They were classified into two groups: high-burden and low-burden groups according to the short version of the Japanese version of the Zarit Caregiver Burden Interview score of ≥13 or ≤12, respectively. The cutoff values of ADL and the combination of related factors associated with high caregiver burden were examined using the receiver operating characteristic curve and decision tree analyses. The cutoff value associated with high caregiver burden was 5 points for the controlling bladder item of the Barthel index (BI) (sensitivity: 90%, specificity: 70%). Regarding the decision tree, the controlling bladder item of BI (≤5 or 10 points) was selected as the first layer and the recipient's age (≤78 or ≥79 years) as the second layer. High caregiver burden was identified in 85.7% of the caregivers in whom the score of controlling bladder of BI was ≤5 points and the patient was aged ≤78 years. A score of ≤5 points for the controlling bladder item of BI along with young recipient age was associated with high caregiver burden that induces depression among caregivers. This approach is useful to identify caregivers with high caregiver burden who are at risk for depression.

Effect of life-space mobility on subjective well-being in aged home-based rehabilitation users with different levels of independence in activities of daily living.

[Purpose] The relationship between quality of life and life-space mobility in community-dwelling older adults has recently been reported. The present study aimed to elucidate this relationship in home-based rehabilitation users with limited life-space mobility and loss of independence in activities of daily living. [Participants and Methods] The study population comprised 33 home-based rehabilitation users. The participants were expected to have a wide range of the level of independence in activities of daily living; therefore, they were categorized into three groups according to the Barthel Index score: independent (95-100 points), moderately disabled (90-65 points), and severely disabled (60-0 points) groups. We examined the relationships among the Philadelphia Geriatric Center Morale Scale, Life-Space Assessment, and Barthel Index scores and age. [Results] We detected a strong positive correlation between the Philadelphia Geriatric Center Morale Scale and Life-Space Assessment scores in the independent group; however, no significant correlations were observed in the moderately and severely disabled groups. [Conclusion] Our findings suggest a relationship between subjective well-being and life-space mobility in home-based rehabilitation users who are mostly independent in activities of daily living. However, owing to the small sample size and characteristics of the scales used in this study, further studies are warranted to verify these results.

Physical therapy for multiple myeloma patients with severely hindered daily living activities due to bone lesions: a report of two cases.

[Purpose] Physical therapy for patients with multiple myeloma requires appropriate exercise intensity and risk management due to osteolytic lesions. However, the optimal strategy for setting exercise intensity remains unclear. We report cases in which physical therapy was performed using the Borg scale and the Common Terminology Criteria for Adverse Events v4.0 as indicators of improvement in the performance of activities of daily living without causing adverse events. [Participants and Methods] Two patients with multiple myeloma, whose performance status was 4, underwent resistance training of the upper and lower limbs and activities of daily living practice in stages according to their functional status. Each exercise was performed for 20 to 40 minutes twice a day for 6 days a week. The exercise intensity was set to 13 on the Borg scale as a guide, and the allowable bone pain was up to Grade 1 according to Common Terminology Criteria for Adverse Events v4.0. [Results] No adverse events occurred in either patient, and the performance status improved to 1 or 2. Subsequently, autologous peripheral hematopoietic stem cell transplantation was performed. [Conclusion] Physical therapy with exercise intensity set to 13 on the Borg scale and Grade 1 per Common Terminology Criteria for Adverse Events v4.0 may safely improve the performance of activities of daily living of patients with multiple myeloma.

Weight Loss Intervention before Cord Blood Transplantation in an Obese Patient with Acute Myeloid Leukemia: A Case Study.

BACKGROUND: A severely obese woman (39.8 kg/m2) with relapsed acute myeloid leukemia was admitted to our hospital to undergo salvage chemotherapy followed by cord blood transplantation (CBT). CASE: During the salvage chemotherapy period, a 70-day weight loss program addressing diet and exercise was administered. After the 70-day intervention, the patient's body weight and body fat mass had decreased (8.6% and 15.0%, respectively) without any adverse events. The number of available cord blood units with total nucleated cells per body weight greater than 2 × 107/kg was zero at admission and two after weight loss; therefore, CBT could be performed. DISCUSSION: Considering this case, we suggest that a weight loss program combining exercise and nutrition therapy may help patients scheduled for hematopoietic stem cell transplantation by focusing on risk management.
