The program incorporates “Simple exercises to replace lymphatic drainage” based on lymphatic flow. The purpose of this study was to consider the feasibility of continuing this program. <strong>Methods:</strong> The participants were patients in the early stages of secondary lower-limb lymphedema after gynecological cancer surgery and lymphedema therapists with more than five years of experience. Patients continued self-care at home after being briefed on the program, and they were analyzed on their self-care continuity status one month later based on a self-administered questionnaire survey and self-care notes. We interviewed the lymphedema therapists about this program to discuss the feasibility of continuing it and obtain feedback. <strong>Results:</strong> The patients who participated in the study were six women who underwent surgery with lymph node dissection for gynecological cancer. The therapists were five nurses and one occupational therapist. The patient understood the importance of all items in the self-care. “Observation,” “Touching,” and “Skin care” were relatively easy to continue. “Lymph drainage” and “Exercise” were continued with “Simple exercises to replace lymphatic drainage”. “Other exercises” were able to continue by adding distance and time to daily activities. Furthermore, “Measurement” and “Recording” became a burden and were difficult to continue. Nonetheless, this program was generally approved by the lymphedema therapists. They also pointed out the content and format of the self-care notes as improvements. <strong>Conclusions: </strong>We found that the self-care supporting program that incorporated “Simple exercises to replace lymphatic drainage” might be feasible to continue self-care for patients with early stages of secondary lower-limb lymphedema. Furthermore, we found that we needed to improve the “Measurement” and “Recording” sections of this program.展开更多

Early or first-episode psychosis patients can be especially vulnerable to physical health, psychological and social consequences of antipsychotic medication weight gain. The aim of this paper is to review diet and exercise lifestyle interventions employed to address these issues. Method: A review of research evidence on lifestyle interventions (diet and exercise) for individuals with early or first-episode psychosis (2000 to 2020) was undertaken. An internet-based literature search employed Medline, PsycINFO, Embase, PubMed and Web of Science. Results: Nine studies meeting the criteria were identified: comprising of three exercise intervention studies, one diet intervention study, and five combined diet and exercise intervention studies. Only one study used a RCT design with prior power analysis to determine participant numbers, two had a RCT design, two had a comparison group and four had no control group. Overall, these studies show that exercise and diet focused interventions may provide beneficial physical and mental health outcomes, but participant engagement and behaviour change may be difficult to achieve in early or first-episode psychosis due to individual factors associated with the experience of psychosis and medication prescribed, and health service related factors. Conclusion: There is a need for evidence-based lifestyle programmes in early or first-episode psychosis that includes individually targeted evidence based exercise and diet interventions. Further appropriately powered RCTs are required to strengthen the evidence base.展开更多
