Among women, breast cancer is the most commonly diagnosed cancer worldwide. Sleep problems impair 40–70% of breast cancer survivors. This randomized controlled trial evaluates the effect of auricular acupuncture on sleep quality in breast cancer survivors suffering from insomnia. Fifty-two female breast cancer survivors with insomnia (mean age 55.73 ± 8.10 years) were randomized either to 10 treatments of auricular acupuncture within five weeks (n = 26), or to a single session of psychoeducation plus an insomnia advice booklet (n = 26). The primary outcome was sleep quality (measured by the Pittsburgh Sleep Quality Index) at week 5. Secondary outcomes were inflammation parameter (interleukin-6), stress, anxiety, depression, quality of life, and fatigue at week 5, and sleep quality, stress, anxiety, depression, quality of life, and fatigue 17 and 29 weeks after randomization. Intention-to-treat analysis showed a significantly stronger increase in sleep quality in the auricular acupuncture group compared to the psychoeducation group (p = 0.031; η²p = 0.094) at week 5. Furthermore, auricular acupuncture improved stress (p = 0.030; η²p = 0.094), anxiety (p = 0.001; η²p = 0.192), and fatigue (p = 0.006; η²p = 0.148) at week 5 compared to psychoeducation. No significant group difference was found concerning the other outcomes at week 5, or in any outcome at week 17 or week 29. No serious adverse events occurred during the study period. In conclusion, a semi-standardized group auricular acupuncture might be an effective and safe intervention in treating insomnia in breast cancer survivors in the short term, and may reduce stress, anxiety, and fatigue as well. Long-term effects remain questionable.

Background Cardiovascular diseases ( CVDs ) and their risk factors need guideline‐oriented treatment to provide the best benefit for patients. These guidelines include recommendations for regular checkups, realized by general medical practitioners. In addition, individuals with CVD or CVD risk factors tend to use complementary methods for their condition. There is limited information on the association between complementary healthcare utilization and the adherence to recommended conventional health care. Methods and Results In this cross‐sectional analysis of the nationally representative 2017 National Health Interview Survey (n=26 742; response rate 80.7%) we examined the prevalence of conventional and complementary healthcare utilization within the past 12 months in individuals with CVD and/or CVD risk factors and the interactions between the two categories of health care. Of all participants, 38.1% reported risk factors for CVD and 11.4% a CVD diagnosis (groups show an overlap). Overall prevalence of visits to conventional and complementary medicine providers and the use of mind–body medicine was high within the population analyzed. Individuals with CVD and/or CVD risk factors using complementary health care were as likely or more likely to consult general practitioners ( CVD : adjusted odds ratio [aOR], 1.17; 95% CI, 0.93–1.47; CVD risk: aOR, 1.21; 95% CI , 1.05–1.39) and medical specialists ( CVD : aOR, 1.38; 95% CI , 1.17–1.64; CVD risk: aOR, 1.42; 95% CI , 1.28–1.58) than those not using complementary health care. Those using complementary health care were as likely to adhere to medical checkup as those not using complementary health care. Conclusions Complementary healthcare utilization use was not associated with a reduced adherence to conventional health care and recommended checkups. The potential positive association of complementary and conventional healthcare utilization needs to be confirmed in further studies.
