Music interventions for chemotherapy-induced nausea and vomiting: a systematic review and meta-analysis.

BACKGROUND: Chemotherapy-induced nausea and vomiting (CINV) is the most common and severe side effects brought by chemotherapeutics. The role of music interventions in relieving CINV is uncertain. The aim of this systematic review was to test the effects of music interventions on three categories of CINV. METHODS: A systematic search was conducted in Cochrane Central Register of Controlled Trials (CENTRAL), Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed, EMBASE, China National Knowledge Infrastructure (CNKI), WanFang, and Chinese Biomedical Database (CBM) in order to capture randomized controlled trials (RCTs) investigating the comparative efficacy of music interventions and others. Two investigators screened, sorted, and extracted the data, and appraised the risk of bias. All statistical analyses were performed using RevMan 5.3 software. RESULTS: The literature search yielded 608 studies of which only ten RCTs fulfilled the eligibility criteria with 632 patients retrieved. Although the duration, the frequency of interventions, and the type of selected music varied across studies, commonly used elements included music listening. Results showed that music interventions were associated with reducing the incidence of anticipatory CINV and lowering the severity of delayed vomiting (MD = - 0.65, 95% CI = - 1.08 to - 0.23). However, strongly controversial results existed in terms of reducing the incidence of acute and delayed CINV, the severity of acute CINV, the severity of delayed nausea, and improving patients' quality of life. CONCLUSIONS: Music interventions may effectively reduce the incidence of anticipatory CINV and relieve the severity of delayed vomiting in patients with chemotherapy based on limited data. However, the conclusion should be interpreted with caution and further research is required to design with large-scale and rigorous methods.

A survey of overall life satisfaction and its association with breast diseases in Chinese women.

To investigate the association between overall life satisfaction and healthy lifestyle, knowledge of breast cancer, physical examination, and detection rate of breast cancer and benign breast disease in Chinese women. In a multicentered breast disease screening program in China, we enrolled 33,057 women aged 45-65 years without prior diagnosis of breast cancer. After completing an epidemiological questionnaire, all participants were examined by clinical breast examination, breast ultrasound, and mammography independently. All breast cancer cases and a selected sample of benign breast diseases were confirmed pathologically. Univariate and multivariate odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to estimate the association between life satisfaction and lifestyle, knowledge of breast cancer, physical examination, and detection rate of breast diseases. Overall life satisfaction was positively associated with women's healthy lifestyle. Compared with less satisfied women, satisfied women were less likely to be smokers (OR = 0.54; 95% CI: 0.47-0.62), have more exercise (OR = 1.49; 95% CI: 1.26-1.75), eat less fried (OR = 0.60; 95% CI: 0.50-0.71), smoked (OR = 0.54, 95% CI: 0.47-0.63), pickled (OR = 0.66, 95% CI: 0.55-0.79), and grilled (OR = 0.63, 95% CI: 0.54-0.74) foods. Satisfied women were more likely to have knowledge of breast cancer (OR = 1.48, 95% CI: 1.29-1.70), and have regular physical examinations (OR = 1.11, 95% CI: 1.01-1.12). Compared to less satisfied women, we found significantly lower detection rate of benign breast diseases (OR = 0.90, 95% CI: 0.82-0.99), and lower but nonsignificant detection rate of breast cancer (OR = 0.66, 95% CI: 0.35-1.25) in satisfied women. Women with a higher overall life satisfaction are more likely to have healthy lifestyle, knowledge of breast cancer, and regular physical examination, thus resulting in a lower detection rate of breast diseases in screening.
