Physical Therapy in Patients with Cancer

Physical therapists often treat cancer patients. Cancer treatment includes chemotherapy, radiotherapy, and surgery, which are being continuously developed and thus increase survival of patients with each cancer diagnosis. More specifically, 5-year survival rates increase with each cancer diagnosis. Cancer patients have many problems including muscle weakness, pulmonary dysfunction, fatigue, and pain. In the end, patients with cancer tend to have a decline in activities of daily living (ADL) and quality of life (QOL). Additionally, cancer patients often have progressive disease, depression, and anxiety. Physical therapy often helps patients regain strength and physical function and improve their QOL and independence of daily living that they may have lost due to cancer or its treatment. Physical therapy has an important role in increasing physical function of cancer patients, cancer survivors, and children with cancer. In the future, physical therapy may be progressively needed for management of cancer patients

Understanding Cachexia, Sarcopenia, and Physical Exercise in Patients with Cancer

Many patients with cancer experience muscle wasting and weakness. Muscle wasting in patients with cancer can be caused by cachexia and sarcopenia. Both cachexia and sarcopenia involve inflammation and oxidative stress. However, they differ in the underlying mechanisms that lead to muscle wasting. Cachexia involves the release of inflammatory cytokines due to cancer, while sarcopenia involves inflammation due to aging. Physical exercise has shown effectiveness for improving physical function, ability, and quality of life (QOL) in patients with cancer cachexia. On the other hand, no studies have investigated the relationship between physical exercise and sarcopenia in elderly patients with cancer. Previous studies showed effectiveness for improving physical function in elderly patients with cancer. In the future, more studies are required on physical exercise in sarcopenic elderly patients with cancer

The benefit of exercise in patients who undergo allogeneic hematopoietic stem cell transplantation

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is increasingly used in the treatment of hematologic cancers such as leukemias, lymphomas, and myeloma and for other hematologic disorders such as primary immunodeficiency, aplastic anemia, and myelodysplasia. Allo-HSCT entails a conditioning regimen of frequent high-dose chemotherapy in combination with total body irradiation, followed by infusion of donor-harvested bone marrow or peripheral blood stem cells. As an aggressive and demanding medical therapy that profoundly impacts patient quality of life (QOL), allo-HSCT is associated with numerous treatment-related physical, psychological, and psychosocial side effects. The procedure can result in decreased respiratory and balance function, skeletal muscle strength, and exercise capacity. Thus, as physical exercise has been shown to positively affect physical and psychosocial function and QOL in allo-HSCT patients, it is a recommended intervention for improving essential functions and offsetting lost exercise capacity after the procedure. Furthermore, recent evidence has shown that physical exercise can influence survival rate and mortality in allo-HSCT patients. This review provides an overview of the current research on the effectiveness of physical exercise for allo-HSCT patients

Voluntary cough intensity and its influencing factors differ by sex in community-dwelling adults

Background: Cough peak flow (CPF) is widely used for measuring voluntary cough intensity. However, the respective factors that affect CPF are not known. The aim of this study was to determine the factors affecting CPF by sex in community-dwelling adults. Method: We recruited participants using posters exhibited at a public gymnasium. Participation was voluntary, and all participants provided informed consent. Nonsmoking community residents (102 males, 49.6 ± 20.2 years of age; 101 females, 51.4 ± 18.4 years of age) participated in this study. The main outcome measures were sex differences in CPF, respiratory function, respiratory muscle strength, thorax extension, and grip strength. Factors affecting CPF by sex were analyzed using multiple regression analysis. Results: All parameters were higher in men than in women. CPF was affected by thorax expansion at the tenth rib, inspiratory muscle strength and forced expiration in 1 s in men, and thorax expansion at the tenth rib, inspiratory reserve volume, and expiratory muscle power in women. A weak negative correlation was observed between CPF and age ( p = −0.24, p < 0.05) in women. Conclusions: The factors affecting CPF differed by sex in community-dwelling adults. Clinical Trial Number: UMIN00002391

Relationship between the Difference in Oxygenated Hemoglobin Concentration Changes in the Left and Right Prefrontal Cortex and Cognitive Function during Moderate-Intensity Aerobic Exercise

Previous studies have indicated that changes in oxygenated hemoglobin concentration (O2Hb) in the prefrontal cortex (PFC) are associated with changes in cognitive function. Therefore, the present study aimed to explore the effect of differences in O2Hb levels in the left and right PFC (L-PFC and R-PFC, respectively) on cognitive function after exercise. This study included 12 healthy male college students. The exercise regimen consisted of 4 min of warm-up and rest each, followed by 20 min of moderate-intensity exercise and 20 min of post-exercise rest. Participants underwent the 2-back cognitive test thrice (pre-exercise, post-exercise, and after the 20 min post-exercise rest period), and their reaction times were recorded. O2Hb levels in the PFC were monitored using functional near-infrared spectroscopy. We analyzed the correlations between changes in post-exercise reaction times and differences in peak O2Hb levels (L-PFC minus R-PFC), area under the curve for O2Hb changes, and increases in the O2Hb slope during exercise. Peak O2Hb, area under the curve (AUC) for O2Hb change, and increase in the slope of O2Hb were significantly correlated with changes in reaction time. These findings provide insight into the mechanism by which O2Hb differences between the L-PFC and R-PFC affect cognitive function

Relationship between Nutrition-Related Problems and Falls in Hemodialysis Patients: A Narrative Review

Falls are a social problem that increase healthcare costs. Hemodialysis (HD) patients need to avoid falling because fractures increase their risk of death. Nutritional problems such as frailty, sarcopenia, undernutrition, protein-energy wasting (PEW), and cachexia may increase the risk of falls and fractures in patients with HD. This review aimed to summarize the impact of frailty, sarcopenia, undernutrition, PEW, and cachexia on falls in HD patients. The reported global incidence of falls in HD patients is 0.85&ndash;1.60 falls per patient per year. HD patients fall frequently, but few reports have investigated the relationship between nutrition-related problems and falls. Several studies reported that frailty and undernutrition increase the risk of falls in HD patients. Nutritional therapy may help to prevent falls in HD patients. HD patients&rsquo; falls are caused by nutritional problems such as iatrogenic and non-iatrogenic factors. Falls increase a person&rsquo;s fear of falling, reducing physical activity, which then causes muscle weakness and further decreased physical activity; this cycle can cause multiple falls. Further research is necessary to clarify the relationships between falls and sarcopenia, cachexia, and PEW. Routine clinical assessments of nutrition-related problems are crucial to prevent falls in HD patients
