Background Previous clinical trials have demonstrated that both acupuncture and sham acupuncture exert significant, non-specific effects on treatment outcomes when compared to no-treatment controls. A recently developed framework (mechanisms in orthodox and complementary and alternative medicine—MOCAM) suggests that the non-specific effects of acupuncture originate from multiple domains (e.g. patient characteristics, acupuncturist skill/technique, the patient–acupuncturist relationship, and the acupuncture environment). However, it remains to be determined precisely how these domains influence the non-specific effects of treatment among patients receiving acupuncture and sham acupuncture in clinical trials. Therefore, we conducted a systematic review to synthesize existing qualitative evidence on how trial participants randomized to acupuncture and sham acupuncture groups experience non-specific effects, regardless of the types of medical condition investigated. Methods This systematic review included primary qualitative studies embedded in randomized controlled trials designed to investigate acupuncture or sham acupuncture interventions. Eligible studies published in English were derived from a search of five international databases. The methodological quality of included studies was evaluated using the Critical Appraisal Skills Programme (CASP) tool. Using a framework synthesis approach, the identified MOCAM framework was adapted based on the synthesis of the available qualitative evidence. Results A total of 20 studies of high methodological quality were included. Our proposed model indicated that the effects of acupuncture may be increased by maintaining a professional status, applying a holistic treatment approach, practicing empathy, and providing patients with an appropriate explanation of the theory behind acupuncture and sham acupuncture. From the patient’s perspective, the efficacy of treatment can be increased by following the lifestyle modification advice provided by acupuncturists, maintaining a positive attitude toward treatment efficacy, actively engaging with acupuncturists during consultation, and making behavioral changes based on experience gained during the trial. Conclusion The results of this study may provide a basis for improving and standardizing key components of non-specific effects in acupuncture treatment, and for improving the isolation of specific effects in future clinical trials involving acupuncture and sham acupuncture.

AbstractOpen-label placebos (OLPs) are placebos without deception in the sense that patients know that they are receiving a placebo. The objective of our study is to systematically review and analyze the effect of OLPs in comparison to no treatment in clinical trials. A systematic literature search was carried out in February 2020. Randomized controlled trials of any medical condition or mental disorder comparing OLPs to no treatment were included. Data extraction and risk of bias rating were independently assessed. 1246 records were screened and thirteen studies were included into the systematic review. Eleven trials were eligible for meta-analysis. These trials assessed effects of OLPs on back pain, cancer-related fatigue, attention deficit hyperactivity disorder, allergic rhinitis, major depression, irritable bowel syndrome and menopausal hot flushes. Risk of bias was moderate among all studies. We found a significant overall effect (standardized mean difference = 0.72, 95% Cl 0.39–1.05, p < 0.0001, I2 = 76%) of OLP. Thus, OLPs appear to be a promising treatment in different conditions but the respective research is in its infancy. More research is needed, especially with respect to different medical and mental disorders and instructions accompanying the OLP administration as well as the role of expectations and mindsets.

IntroductionCommunity advisory boards (CABs) continue to gain wide use and acceptance in global health research including in HIV clinical trials. They provide means through which community concerns regarding the trial can be considered by the research team, and provide an important platform of communication between the researchers and the community about study goals. Therefore, this systematic review protocol will guide the review of qualitative evidence on the ethical roles of CABs in HIV clinical trials based on the three fundamental ethical principles: respect for the person, beneficence and justice.Methods and analysisThis systematic review of qualitative evidence will involve searching four medical databases: PubMed, ScienceDirect, CINAHL and Cochrane Library. Additionally, other relevant evidence will be obtained through hand searching and grey literature. Searches will be limited to studies published in the English language from 1989 (the year that CABs were first established in HIV clinical trials) to 2019. Articles searched will be screened by two independent authors based on inclusion and exclusion criteria. Included articles will be appraised for quality using the Critical Appraisal Skills Programme checklist and followed by qualitative data extraction. Findings will be analysed based on the meta-aggregative approach with the aid of EPPI-Reviewer 4 web-based software.Ethics and disseminationEthical approval does not apply to this review. Data will be disseminated through scientific conferences and peer-reviewed journals to inform policies and stake-holders about the ethical role of CABs.PROSPERO registration numberCRD42019133787.

Background. Insomnia is a prominent complaint of cancer patients that can significantly affect their quality of life and symptoms related to sleep quality. Conventional drug approaches have a low rate of success in alleviating those suffering insomnia. The aim of this systematic review was to assess the efficacy of acupuncture in the management of cancer-related insomnia. Methods. A total of 12 databases were searched from their inception through January 2016 without language restriction. Randomized controlled trials (RCTs) and quasi-RCTs were included if acupuncture was used as the sole intervention or as an adjunct to another standard treatment for any cancer-related insomnia. The data extraction and the risk of bias assessments were performed by 2 independent reviewers. Results. Of the 90 studies screened, 6 RCTs were included. The risk of bias was generally unclear or low. Three RCTs showed equivalent effects on the Pittsburgh Sleep Quality Index and 2 RCTs showed the similar effects on response rate to those of conventional drugs at the end of treatment. The other RCT showed acupuncture was better than hormone therapy in the numbers of hours slept each night and number of times woken up each night. The 3 weeks of follow-up in 2 RCTs showed superior effects of acupuncture compared with conventional drugs, and a meta-analysis showed significant effects of acupuncture. Two RCTs tested the effects of acupuncture on cancer-related insomnia compared with sham acupuncture. One RCT showed favourable effects, while the other trial failed to do so. Conclusion. There is a low level of evidence that acupuncture may be superior to sham acupuncture, drugs or hormones therapy. However, the number of studies and effect size are small for clinical significance. Further clinical trials are warranted.

The aim of this systematic review was to summarize randomized clinical trials (RCTs) assessing the effectiveness of acupuncture as published in Korean literature. Systematic searches were conducted on eight Korean medical databases. Manual searches were also conducted through eight major Korean medical journals. The methodological quality was assessed using a Jadad score. Studies evaluating needle acupuncture or auricular acupuncture (AA) with or without electrical stimulation were considered if they were sham or placebo-controlled or controlled against a comparative intervention. We also excluded acupuncture as an adjuvant to other treatments and other forms of acupuncture were excluded. Seven hundred and nine possibly relevant studies were identified and 10 RCTs were included. The methodological quality of the trials was generally poor. Manual acupuncture was compared to placebo acupuncture in four studies of patients with chronic low back pain, shoulder pain, premenstrual syndrome and allergic rhinitis. Three studies tested AA (two trials) and electroacupuncture (one trial) against no treatment, while three trials compared acupuncture with other active therapeutic controls. The methodological limitations of the included trials make their contribution to the current clinical evidence of acupuncture somewhat limited. The trial for premenstrual syndrome, shoulder pain and chronic low back pain added a limited contribution among those included RCTs. However, well-designed RCTs of acupuncture with a rigorous methodology are in progress or have been completed in Korea and will contribute to establish or contribute to the current progress of research in this field.

Background: Radiation-induced xerostomia is one of the most common symptoms experienced by cancer patients. The aim of our study is to evaluate the preventive and therapeutic effect of acupuncture for radiation-induced xerostomia in cancer patients. Methods: Eight databases were searched for all published randomized clinical trials (RCTs) on acupuncture for radiation-induced xerostomia in cancer patients up to December 31, 2019. Manual searching included other conference abstracts and reference lists. Meta-analysis was conducted using Revman V.5.3, and risks of bias for included studies was assessed following the Cochrane Handbook. Results: Eight clinical trials (725 participants) were analyzed, and 3 were included in a meta-analysis. All included trials had a high risk of bias, such as selection, performance, and detection bias. Analysis indicated favorable effects of acupuncture regarding the improvement of xerostomia symptoms (MD −3.05, P = 0.02, 95% CI −5.58 to −0.52), compared with sham acupuncture. There were no significant differences between real acupuncture and sham acupuncture regarding the stimulated salivary flow rate (MD 0.37, P = 0.08, 95% CI −0.05 to 0.79) and unstimulated salivary flow rate (MD 0.09, P = 0.12, 95% CI −0.02 to 0.21), which were whole salivary flow rate. Compared with no acupuncture (standard oral care, usual care, or no treatment), acupuncture produced a significant improvement in patient-reported xerostomia, without causing serious adverse effects. However, a Grading of Recommended Assessments analysis revealed that the quality of all acupuncture outcome measures was low. Conclusion: The present meta-analysis and systematic review suggests that acupuncture is effective at improving xerostomia symptoms in cancer patients but not at objective salivary flow measurements. The evidence is still limited due to the low quality of the published studies.

Background. Idiopathic pulmonary fibrosis (IPF) is a major global health problem. The prevalence of the disease appears to be increasing. There is no curative therapy for IPF except lung transplantation. Chinese herbal medicines (CHMs) are showing promise for treatment of IPF. However, their effectiveness and safety are still unclear and deserve further investigation. The aim of this systematic review is to access the efficacy and safety of CHMs in treating IPF. Methods. The protocol of this review is registered at PROSPERO. We searched seven main databases for randomized clinical trials (RCTs) on CHMs for IPF from their inception to June 4, 2018. The methodological quality of RCTs was assessed using the Cochrane risk of bias tool. All trials included were analyzed according to the criteria of the Cochrane Handbook. Review Manager 5.3, R-3.5.2 software, and Grade pro GDT web solution were used for data synthesis and analysis. Results. Thirteen randomized clinical trials enrolling 733 patients were included. All trials included had clear outcome indicators. The methodological quality of included trials was generally “poor.” Few trials reported methods of randomization. One trial on Xuefu-zhuyu capsule assessed rate of acute exacerbation and mortality after treatment for 72 weeks and found no statistically significant difference between two groups. This meta-analysis demonstrated a significant improvement in QOL of IPF patients when CHMs was applied or combined with conventional medicine treatment. 6MWT was significantly improved in IPF patients after using CHMs or combined with conventional medicine treatment. CHMs treatment also had a certain improvement in TLC and DLCO, but the effect on FVC was not significant. Besides, CHMs failed to provide benefits in terms of PaO2. The reported adverse events were not obvious and severe. Conclusions. Some CHMs seem effective and safe as alternative remedies for patients with IPF, suggesting that further study of CHMs in the treatment of IPF is warranted. Although this systematic review suggests that CHMs may have positive effect on quality of life, 6-minute walk test distance, and lung function (TLC, DLOC%) and seem to be relatively safe during the course of treatment, the results must be treated with great caution because of the methodological flaws of the included trials. Long-term and high-quality trials are needed in the future to provide clear evidence for the use of CHMs.
