Exercise Training for Improving Patient-Reported Outcomes in Patients With Advanced-Stage Cancer: A Systematic Review and Meta-Analysis.

CONTEXT: Patients with advanced-stage cancer often suffer many physical and psychological symptoms. Exercise has been shown to improve quality of life (QoL), decrease cancer-related symptoms, and maintain or improve functional status in cancer survivors or patients with early stage cancer. However, the effect of exercise on these outcomes in patients with advanced-stage cancer is unclear. OBJECTIVES: This meta-analysis aimed to assess the effectiveness of exercise interventions for patients with advanced-stage cancer in improving cancer-related symptoms and functional status outcomes. METHODS: We conducted a comprehensive literature search in PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and Web of Science from their inception to February 3, 2019, to include randomized controlled trials (RCTs) comparing exercise and usual care for improving outcomes in patients with advanced-stage cancer. Two reviewers independently screened the studies, extracted data of interest, and assessed the risk of bias of individual RCTs using the Cochrane Handbook, Version 5.1.0. RESULTS: About 15 RCTs enrolling 1208 patients were included. Compared with usual care, exercise showed a significant improvement in QoL (standardized mean difference [SMD] 0.22; 95% CI 0.06-0.38; P = 0.009), fatigue (SMD -0.25; 95% CI -0.45 to -0.04; P = 0.02), insomnia (SMD -0.36; 95% CI -0.56 to -0.17; P = 0.0002), physical function (SMD 0.22; 95% CI 0.05-0.38; P = 0.009), social function (SMD 0.18; 95% CI 0.02-0.34; P = 0.03), and dyspnea reduction (SMD -0.18; 95% CI -0.34 to -0.01; P = 0.03). CONCLUSION: Exercise serves as an effective intervention to improve QoL and alleviate fatigue, insomnia, dyspnea, and physical and social functions for patients with advanced-stage cancer.

A facile solution route to deposit TiO2 nanowire arrays on arbitrary substrates.

A facile solution-based technique was developed to grow vertically aligned TiO2 nanowires with predominantly anatase phase on arbitrary substrates of stainless steel, glass, silicon wafer and carbon cloth at the low temperature of 80 °C and in an open atmosphere.
