Adverse Events of Auricular Therapy: A Systematic Review

The aim of this study was to systematically evaluate the literature on adverse events associated with auricular therapy (AT). Case reports, case series, surveys, and all types of clinical trials reporting adverse events of AT were included. Relevant articles were mainly retrieved from 13 electronic databases and seven Chinese journals on complementary medicine. AT-related adverse events were reported in 32 randomized controlled trials, five uncontrolled clinical trials, four case reports, and two controlled clinical trials. For auricular acupuncture, the most frequently reported adverse events were tenderness or pain at insertion, dizziness, local discomfort, minor bleeding and nausea, and so forth. For auricular acupressure, local skin irritation and discomfort, mild tenderness or pain, and dizziness were commonly reported. Skin irritation, local discomfort, and pain were detected in auricular electroacupuncture, and minor infection was identified in auricular bloodletting therapy. Most of these events were transient, mild, and tolerable, and no serious adverse events were identified. Our findings provide preliminary evidence that AT is a relatively safe approach. Considering the patients safety, prospective or retrospective surveys are needed in future research to gather practitioner-reported and patient-reported adverse events on AT, and the quality of adverse events reporting in future AT trials should be improved.

Acupuncture-Point Stimulation for Postoperative Pain Control: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

The purpose of this study was to evaluate the effectiveness of Acupuncture-point stimulation (APS) in postoperative pain control compared with sham/placebo acupuncture or standard treatments (usual care or no treatment). Only randomized controlled trials (RCTs) were included. Meta-analysis results indicated that APS interventions improved VAS scores significantly and also reduced total morphine consumption. No serious APS-related adverse effects (AEs) were reported. There is Level I evidence for the effectiveness of body points plaster therapy and Level II evidence for body points electroacupuncture (EA), body points acupressure, body points APS for abdominal surgery patients, auricular points seed embedding, manual auricular acupuncture, and auricular EA. We obtained Level III evidence for body points APS in patients who underwent cardiac surgery and cesarean section and for auricular-point stimulation in patients who underwent abdominal surgery. There is insufficient evidence to conclude that APS is an effective postoperative pain therapy in surgical patients, although the evidence does support the conclusion that APS can reduce analgesic requirements without AEs. The best level of evidence was not adequate in most subgroups. Some limitations of this study may have affected the results, possibly leading to an overestimation of APS effects.

Auricular therapy for chronic pain management in adults: A synthesis of evidence.

OBJECTIVE To evaluate the efficacy and safety of auricular therapy (AT) on chronic pain. METHODS A systematic review. Randomized controlled trials investigating AT for chronic pain were retrieved and RevMan 5.3 was used for meta-analysis. RESULTS Fifteen trials were included. The overall assessment indicated that AT could be a promising intervention for chronic pain relief. Meta-analyses showed that AT decreased pain intensity, especially for chronic low back pain and chronic tension headache. The lasting effect of AT was not obvious, and it began to diminish 3 months after the completion of treatment. CONCLUSIONS AT may positively control pain intensity for patients with chronic pain. However, due to the significant heterogeneity and methodological flaws identified in the analyzed trials, the current evidence on AT for chronic pain management is still uncertain. More rigorously designed large-scale randomized controlled trials are required to evaluate the efficacy of AT for patients with chronic pain.

Sham Acupressure Controls Used in Randomized Controlled Trials: A Systematic Review and Critique

Objectives To explore the commonly utilized sham acupressure procedures in existing acupressure trials, and to assess whether different types of sham interventions yield different therapeutic outcomes, and, as far as possible, to identify directions for the future development of an adequate sham acupressure method. Methods Randomized controlled trials comparing true acupressure with sham interventions were included. Thirteen electronic databases were adopted to locate relevant studies from inception to July 3, 2014. Meanwhile, eight Chinese journals on complementary and alternative medicine were manually searched to locate eligible articles. In addition, eligible studies listed in the reference lists of the included papers and other related systematic reviews on acupressure were also screened to further search any potentially eligible trials. Methodological quality of the included studies was evaluated using the risk of bias assessment tool developed by the Cochrane Back Review Group. Descriptive analysis was adopted to summarize the therapeutic outcomes. Results Sixty-six studies with 7265 participants were included. Methodological quality of the included trials was generally satisfactory. Six types of sham acupressure approaches were identified and “non-acupoint” stimulation was the most frequently utilized sham point while an acupressure device was the most commonly used approach for administering sham treatments. Acupressure therapy was a beneficial approach in managing a variety of health problems and the therapeutic effect was found to be more effective in the true acupressure groups than that in the sham comparative groups. No clear association could be identified between different sham acupressure modalities and the reported treatment outcomes. Conclusions A great diversity of sham acupressure controls have been used in clinical practice and research. A solid conclusion whether different sham alternatives are related to different treatment outcomes cannot be derived because of significant clinical heterogeneity among the analyzed trials. Non-acupoints are generally recommended but the definite locations should be identified with caution. For studies using single sham acupoints on hands or legs, it is suggested to apply identical acupressure devices on the same acupoint as in the active intervention without any stimulation. While for studies on pain, stimulation of sham acupoints should be avoided.

Current Evidence on Auricular Therapy for Chemotherapy-Induced Nausea and Vomiting in Cancer Patients: A Systematic Review of Randomized Controlled Trials

Auricular therapy (AT) has been historically viewed as a convenient approach adjunct to pharmacological therapy for cancer patients with chemotherapy-induced nausea and vomiting (CINV). The aim of this study was to assess the evidence of the therapeutic effect of AT for CINV management in cancer patients. Relevant randomized controlled trials were retrieved from 12 electronic databases without language restrictions. Meanwhile, manual search was conducted for Chinese journals on complementary medicine published within the last five years, and the reference lists of included studies were also checked to identify any possible eligible studies. Twenty-one studies with 1713 participants were included. The effect rate of AT for managing acute CINV ranged from 44.44% to 93.33% in the intervention groups and 15% to 91.67% in the control groups. For delayed CINV, it was 62.96% to 100% and 25% to 100%, respectively. AT seems to be a promising approach in managing CINV. However, the level of evidence was low and the definite effect cannot be concluded as there were significant methodological flaws identified in the analyzed studies. The implications drawn from the 21 studies put some clues for future practice in this area including the need to conduct more rigorously designed randomized controlled trials.

Assessment of Breathlessness in Lung Cancer: Psychometric Properties of the Dyspnea-12 Questionnaire

CONTEXT The Dyspnea-12 (D-12) Questionnaire is a well-validated instrument in respiratory illnesses for breathlessness assessment, but its psychometric properties have not been tested in lung cancer. OBJECTIVE To demonstrate the psychometric properties of the D-12 in lung cancer patients. METHODS Baseline data from a lung cancer feasibility trial were adopted for this analysis. D-12 and a series of patient-reported tools, including five Numeric Rating Scales (NRS), the Hospital Anxiety and Depression Scale (HADS), and the Lung Cancer Symptom Scale (LCSS), were used for the psychometric assessment. Spearmans correlation coefficients (rs) were used to estimate the convergent validity of the D-12 with the NRS, HADS, and LCSS. Exploratory factor analysis was performed to examine construct validity. Reliability was tested by Cronbachs alpha and item-to-total correlations. D-12 score difference between patients with or without anxiety, depression, and chronic obstructive pulmonary disease (COPD) was explored to identify its discriminate performance. RESULTS One hundred and one lung cancer patients were included. There were significantly positive correlations between the D-12 and the HADS, LCSS, and NRS measuring breathlessness severity and its associated affective distress. Factor analysis clearly identified two components (physical and emotional) of the D-12. Cronbachs alpha for D-12 total, physical, and emotional subscales was 0.95, 0.92, and 0.94, respectively. Patients with anxiety or depression demonstrated significantly higher D-12 scores than those without it, and patients with COPD reported significantly more severe breathlessness than those without COPD. CONCLUSION The D-12 is a valid and reliable self-reported questionnaire for use in breathlessness assessment in lung cancer patients.

Current Research Status of Palliative Care in Mainland China

Objectives: This study aimed to obtain an overview of the current research status of palliative care in Mainland China and identify research directions for future studies by characterizing palliative care studies conducted among patients with any life-limiting illness in Mainland China and published in a peer-reviewed journal before November 2016. Methods: A review guide with 7 categories was initially developed based on existing international palliative care definitions and guidelines through content analysis. Ten databases were used to identify relevant studies from the inception of online cataloging to November 2016. Studies conducted in Mainland China and their research topic that fell within one of the categories of the review guide were included for further analysis. Descriptive analysis was adopted to summarize the relevant findings. Results: 54 studies found to be relevant were included for the analysis. Three studies on “palliative care education and training” (category 1) asserted that education and training programs were scant in Mainland China and that only 1 program had been devised within the health-care context of Shanghai. Five studies on “palliative care screening and timely identification” (category 2) highlighted the absence of early screening criteria or checklists and referral procedures for palliative care. Thirty-one studies on “palliative care needs assessment (n = 12/31) and implementation (n = 19/31)” (category 3) were identified, and various methodological flaws were observed in most of these included studies. Twelve studies on “advanced decision-making” (category 4) were identified, all of which focused on investigating the attitudes of patients with cancer, their families, and/or health-care professionals toward advanced decision-making only. The percentage of patients, family members, and health-care professionals who held positive attitudes toward advanced decision-making were varied and suboptimal, particularly for family members (51.4%-58.0%). Five studies on “caring for patients at the end of life” (category 5) were identified, and the experience of health-care professionals in caring for those patients was explored. No studies relating to “death and bereavement care” (Category 6) and “psychological support for palliative care providers” (Category 7) were identified. Conclusion: The current research status of palliative care in Mainland China remains at an early stage with minimal palliative care services used. Although several knowledge gaps were identified, the first step, which should be addressed, is assessing the palliative care needs. An appropriate and ongoing needs assessment could provide important information for constructing comprehensive education and training programs of palliative care, identifying prognostic factors of timely palliative care referral, and developing evidence-based and tailored palliative care services.

Warm-needle moxibustion for spasticity after stroke: A systematic review of randomized controlled trials

BACKGROUND Spasticity is a common post-stroke complication, and it results in substantial deterioration in the quality of life of patients. Although potential positive effects of warm-needle moxibustion on spasticity after stroke have been observed, evidence on its definitive effect remains uncertain. OBJECTIVES This study aimed to summarize clinical evidence pertaining to therapeutic effects and safety of warm-needle moxibustion for treating spasticity after stroke. DESIGN Randomized controlled trials were reviewed systematically on the basis of the Cochrane Handbook for Systematic Reviews of Interventions. The report follows the PRISMA statement. METHODS Ten electronic databases (PubMed, CENTRAL, EMBASE, AMED, CINAHL, Web of Science, CBM, CNKI, WanFang, and VIP) were explored, and articles were retrieved manually from two Chinese journals (The Journal of Traditional Chinese Medicine and Zhong Guo Zhen Jiu) through retrospective search. Randomized controlled trials with warm-needle moxibustion as treatment intervention for patients with limb spasm after stroke were included in this review. The risk of bias assessment tool was utilized in accordance with Cochrane Handbook 5.1.0. All included studies reported spasm effect as primary outcome. Effect size was estimated using relative risk, standardized mean difference, or mean difference with a corresponding 95% confidence interval. Review Manager 5.3 was utilized for meta-analysis. RESULTS Twelve randomized controlled trials with certain methodological flaws and risk of bias were included, and they involved a total of 878 participants. Warm-needle moxibustion was found to be superior to electroacupuncture or acupuncture in reducing spasm and in promoting motor function and daily living activities. Pooled results for spasm effect and motor function were significant when warm-needle moxibustion was compared with electroacupuncture or acupuncture. A comparison of daily living activities indicated significant differences between warm-needle moxibustion and electroacupuncture. However, no difference was observed between warm-needle moxibustion and acupuncture. CONCLUSIONS Warm-needle moxibustion may be a promising intervention to reduce limb spasm as well as improve motor function and daily living activities for stroke patients with spasticity. However, evidence was not conclusive. Rigorously designed randomized controlled trials with sample sizes larger than that in the included trials should be conducted for verification.

Auricular therapy for lactation: A systematic review

BACKGROUND Support for breastfeeding has been a matter of considerable interest in healthcare. In the field of traditional and complementary medicine, the effectiveness of auricular therapy on lactation has been investigated by several clinical studies. AIM AND OBJECTIVES This review was mainly performed to assess the current evidence of auricular therapy on lactation. The objectives were to assess the current evidence of AT for lactation, examine the intervention protocols and outcome measures adopted by the studies included, and inform clinical application and future research in this area. STUDY DESIGN Systematic review. METHOD Narrative synthesis methodology was used to incorporate diverse forms of evidence within this systematic review. RESULTS Twenty-three randomized controlled trials and three non-randomized controlled trials were identified, of which 25 studies applied auricular acupressure with vaccaria seeds as the sole form of auricular therapy. Relative risks calculated on the onset of lactation and milk production are all less than 1. These results indicate that women in the auricular therapy group lactated earlier than their counterparts in the control group and the risk of low milk production was reduced while on auricular therapy. Absolute risk differences showed magnitude of effect ranging from small to medium. Standardized mean differences calculated on serum prolactin data generally favor auricular therapy over routine care. Overall, mothers treated by auricular therapy exhibited better lactation outcomes. CONCLUSION The available data show evidence of benefits for postpartum lactation from auricular therapy. However, research using a more stringent design, standardized protocol, and valid outcome measures are warranted before it can be considered to be evidence-based practice. Issues from the current studies are highlighted and may serve to inform future trials.

Acupoints Stimulation for Anxiety and Depression in Cancer Patients: A Quantitative Synthesis of Randomized Controlled Trials

This study aims at concluding the current evidence on the therapeutic effects of acupoints stimulation for cancer patients with anxiety and depression. Randomized controlled trials using acupoints stimulation for relieving anxiety and/or depression in cancer patients were searched, and 11 studies were finally included, of which eight trials compared acupoints stimulation with standard methods of treatment/care, and acupoints stimulation showed significantly better effects in improving depression than using standard methods of treatment/care. Four studies compared true acupoints stimulation with sham methods, and no significant differences can be found between groups for either depression or anxiety, although the pooled effects still favored true intervention. For the five studies that evaluated sleep quality, the results were conflicting, with three supporting the superiority of acupoints stimulation in improving sleep quality and two demonstrating no differences across groups. Acupoints stimulation seems to be an effective approach in relieving depression and anxiety in cancer patients, and placebo effects may partially contribute to the benefits. However, the evidence is not conclusive due to the limited number of included studies and the clinical heterogeneity identified among trials. More rigorous designed randomized, sham-controlled studies are necessary in future research.
