Abstract: The present systematic review and meta-analysis was undertaken to evaluate the effects of acupuncture in women with breast cancer (BC), focusing on patient-reported outcomes (PROs). Methods: A comprehensive literature search was carried out for randomized controlled trials (RCTs) reporting PROs in BC patients with treatment-related symptoms after undergoing acupuncture for at least four weeks. Literature screening, data extraction, and risk bias assessment were independently carried out by two researchers. Results: Out of the 2, 524 identified studies, 29 studies representing 33 articles were included in this meta-analysis. At the end of treatment (EOT), the acupuncture patients’ quality of life (QoL) was measured by the QLQ-C30 QoL subscale, the Functional Assessment of Cancer Therapy-Endocrine Symptoms (FACT-ES), the Functional Assessment of Cancer Therapy–General/Breast (FACT-G/B), and the Menopause-Specific Quality of Life Questionnaire (MENQOL), which depicted a significant improvement. The use of acupuncture in BC patients lead to a considerable reduction in the scores of all subscales of the Brief Pain Inventory-Short Form (BPI-SF) and Visual Analog Scale (VAS) measuring pain. Moreover, patients treated with acupuncture were more likely to experience improvements in hot flashes scores, fatigue, sleep disturbance, and anxiety compared to those in the control group, while the improvements in depression were comparable across both groups. Long-term follow-up results were similar to the EOT results. Conclusions: Current evidence suggests that acupuncture might improve BC treatment-related symptoms measured with PROs including QoL, pain, fatigue, hot flashes, sleep disturbance and anxiety. However, a number of included studies report limited amounts of certain subgroup settings, thus more rigorous, well-designed and larger RCTs are needed to confirm our results.
PURPOSE: Cancer-related fatigue (CRF) is a common symptom among patients with cancer. The efficacy of placebo, however, was never the main objective of any meta-analysis. Predicting the efficacy of placebo may facilitate researchers in designing future clinical trials for the treatment of CRF.
METHODS: We performed a systematic review searching for prospective clinical trials comparing any treatment versus placebo for the treatment of CRF. We included studies that enrolled patients with any primary site of neoplasia and any stage of cancer. We excluded all studies that assessed fatigue related to any treatment. The primary endpoint of this study is the mean effect of placebo on fatigue according to the Functional Assessment of Chronic Illness (FACIT-F) and Brief Fatigue Inventory (BFI) scales. The secondary endpoint was the proportion of patients who reported improvement in fatigue (response rate).
RESULTS: We found 520 studies, and 29 studies with 3758 participants were included in the meta-analysis. Placebo had a mean effect of + 4.88 (95%CI + 2.45 to + 7.29) using the FACIT-F scale, although it was statistically worse than the interventions studied (p = 0.005). Using the BFI scale, placebo had an average effect of + 0.64 (95%CI + 0.02 to + 1.30), although it was also worse than the other interventions studied (p = 0.002). In terms of the response rate, 29% (95%CI 25-32%) of patients taking a placebo reported a significant improvement in CRF compared with 36% of patients treated with other interventions (p = 0.030).
CONCLUSIONS: Placebo treatments had a significant effect on CRF, and predicting these effects may help design future studies for CRF.
Background. Anorexia nervosa (AN) is a disabling, deadly and costly mental disorder. Until recently, treatment recommendations were based on expert opinion and limited evidence. The aim of this systematic review is to synthesise recent evidence on established and emerging AN treatments and to forecast trends for future developments. Methods. We systematically review trials of established treatments and associated process outcome studies from the last 5 years, published since a previous review in this journal. ‘Established’ treatments were those that are widely used in AN, recommended by guidelines and/or have been tested in at least one large randomised controlled trial. Secondly, we summarise emerging treatments for AN, i.e. those that have only been (or are currently being) tested in proof-of concept, feasibility or pilot trials. Results. We identified 19 published trials of established treatments (15 of high or moderate quality), mostly assessing psychological therapies (<i>n</i> = 17). We also found 11 published trials of emerging treatments, and a total of 34 registered, as yet unpublished trials. Promising emerging treatments include cognitive remediation therapy, exposure therapy and non-invasive neuromodulation. Conclusions. Evidence generation on the treatment of AN has dramatically accelerated, with our understanding of the role of family-based approaches for adolescents more nuanced and a range of psychological approaches available for the treatment of adults. Evidence on emerging treatments and from forthcoming trials suggests that there is a shift towards more targeted brain-based interventions. Future studies need to focus on elucidating mechanisms of action of treatments and what works best for whom. (PsycInfo Database Record (c) 2021 APA, all rights reserved)
OBJECTIVE: To critically assess the effectiveness and safety of acupuncture for treating hot flashes (HFs) among breast cancer (BC) patients, and to get much more highly compelling evidence then to guide clinical practice.
METHODS: Comprehensive systematic literature searches were carried out for identifying randomized controlled trials and observational studies (OSs) published before January 2015. The meta-analysis (MA) was performed by Review Manager 5 software if data could be merged routinely, if not descriptions would be given.
RESULTS: A total of 18 studies were eligible ultimately. With respect to HFs frequency, the MA during treatment showed a significant difference (MD = -1.78, 95% confidence intervals [95% CIs]: -3.42--0.14), but no statistical differences were observed when posttreatment or follow-up period. While electroacupuncture versus applied relaxation, they both helped to promote HFs markedly but did not reveal statistically significance between them. Referring to Kupperman's index, all the treatment brought out great assistance when compared with baseline conditions, and there was significant difference between real acupuncture sham acupuncture (posttreatment: MD = -4.40, 95% CI: -6.77--2.03; follow-up: MD = -4.30, 95% CI: -6.52--2.08). In terms of OS, 7 prospective single arm studies focused on exploring the efficacy of traditional acupuncture, and all revealed moderate or great benefit for BC patients suffering from HFs.
CONCLUSIONS: Acupuncture still appeared to be an efficacious therapeutic strategy, especially for the less/no side effects. Because of its widespread acceptance and encouraging effectiveness for improving HFs, much more high-quality studies are in need urgently.
BACKGROUND: Hip osteoarthritis (OA) is a major cause of pain and functional limitation. Few hip OA treatments have been evaluated for safety and effectiveness. Acupuncture is a traditional Chinese medical therapy which aims to treat disease by inserting very thin needles at specific points on the body.
OBJECTIVES: To assess the benefits and harms of acupuncture in patients with hip OA.
SEARCH METHODS: We searched Cochrane CENTRAL, MEDLINE, and Embase all through March 2018.
SELECTION CRITERIA: We included randomized controlled trials (RCTs) that compared acupuncture with sham acupuncture, another active treatment, or no specific treatment; and RCTs that evaluated acupuncture as an addition to another treatment. Major outcomes were pain and function at the short term (i.e. < 3 months after randomization) and adverse events.
DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane.
MAIN RESULTS: Six RCTs with 413 participants were included. Four RCTs included only people with OA of the hip, and two included a mix of people with OA of the hip and knee. All RCTs included primarily older participants, with a mean age range from 61 to 67 years, and a mean duration of hip OA pain from two to eight years. Approximately two-thirds of participants were women. Two RCTs compared acupuncture versus sham acupuncture; the other four RCTs were not blinded. All results were evaluated at short term (i.e. four to nine weeks after randomization).In the two RCTs that compared acupuncture to sham acupuncture, the sham acupuncture control interventions were judged believable, but each sham acupuncture intervention was also judged to have a risk of weak acupuncture-specific effects, due to placement of non-penetrating needles at the correct acupuncture points in one RCT, and the use of penetrating needles not inserted at the correct points in the other RCT. For these two sham-controlled RCTs, the risk of bias was low for all outcomes.The combined analysis of two sham-controlled RCTs gave moderate quality evidence of little or no effect in reduction in pain for acupuncture relative to sham acupuncture. Due to the small sample sizes in the studies, the confidence interval includes both the possibility of moderate benefit and the possibility of no effect of acupuncture (120 participants; Standardized Mean Difference (SMD) -0.13, (95% Confidence Interval (CI) -0.49 to 0.22); 2.1 points greater improvement with acupuncture compared to sham acupuncture on 100 point scale (i.e., absolute percent change -2.1% (95% CI -7.9% to 3.6%)); relative percent change -4.1% (95% CI -15.6% to 7.0%)). Estimates of effect were similar for function (120 participants; SMD -0.15, (95% CI -0.51 to 0.21)). No pooled estimate, representative of the two sham-controlled RCTs, could be calculated or reported for the quality of life outcome.The four other RCTs were unblinded comparative effectiveness RCTs, which compared (additional) acupuncture to four different active control treatments.There was low quality evidence that addition of acupuncture to the routine primary care that RCT participants were receiving from their physicians was associated with statistically significant and clinically relevant benefits, compared to the routine primary physician care alone, in pain (1 RCT; 137 participants; mean percent difference -22.9% (95% CI -29.2% to -16.6%); relative percent difference -46.5% (95% CI -59.3% to -33.7%)) and function (mean percent difference -19.0% (95% CI -24.41 to -13.59); relative percent difference -38.6% (95% CI -49.6% to -27.6%)). There was no statistically significant difference for mental quality of life and acupuncture showed a small, significant benefit for physical quality of life.The effects of acupuncture compared with either advice plus exercise or NSAIDs are uncertain.We are also uncertain whether acupuncture plus patient education improves pain, function, and quality of life, when compared to patient education alone.In general, the overall quality of the evidence for the four comparative effectiveness RCTs was low to very low, mainly due to the potential for biased reporting of patient-assessed outcomes due to lack of blinding and sparse data.Information on safety was reported in four RCTs. Two RCTs reported minor side effects of acupuncture, which were primarily minor bruising, bleeding, or pain at needle insertion sites. Four RCTs reported on adverse events, and none reported any serious adverse events attributed to acupuncture.
AUTHORS' CONCLUSIONS: Acupuncture probably has little or no effect in reducing pain or improving function relative to sham acupuncture in people with hip osteoarthritis. Due to the small sample size in the studies, the confidence intervals include both the possibility of moderate benefits and the possibility of no effect of acupuncture. One unblinded trial found that acupuncture as an addition to routine primary physician care was associated with benefits on pain and function. However, these reported benefits are likely due at least partially to RCT participants' greater expectations of benefit from acupuncture. Possible side effects associated with acupuncture treatment were minor.
Despite wide use in clinical practice, acupuncture remains a controversial treatment for chronic pain. Our objective was to update an individual patient data meta-analysis to determine the effect size of acupuncture for 4 chronic pain conditions. We searched MEDLINE and the Cochrane Central Registry of Controlled Trials randomized trials published up until December 31, 2015. We included randomized trials of acupuncture needling versus either sham acupuncture or no acupuncture control for nonspecific musculoskeletal pain, osteoarthritis, chronic headache, or shoulder pain. Trials were only included if allocation concealment was unambiguously determined to be adequate. Raw data were obtained from study authors and entered into an individual patient data meta-analysis. The main outcome measures were pain and function. An additional 13 trials were identified, with data received for a total of 20,827 patients from 39 trials. Acupuncture was superior to sham as well as no acupuncture control for each pain condition (all <i>P</i> < .001) with differences between groups close to .5 SDs compared with no acupuncture control and close to .2 SDs compared with sham. We also found clear evidence that the effects of acupuncture persist over time with only a small decrease, approximately 15%, in treatment effect at 1 year. In secondary analyses, we found no obvious association between trial outcome and characteristics of acupuncture treatment, but effect sizes of acupuncture were associated with the type of control group, with smaller effects sizes for sham controlled trials that used a penetrating needle for sham, and for trials that had high intensity of intervention in the control arm. We conclude that acupuncture is effective for the treatment of chronic pain, with treatment effects persisting over time. Although factors in addition to the specific effects of needling at correct acupuncture point locations are important contributors to the treatment effect, decreases in pain after acupuncture cannot be explained solely in terms of placebo effects. Variations in the effect size of acupuncture in different trials are driven predominantly by differences in treatments received by the control group rather than by differences in the characteristics of acupuncture treatment. PERSPECTIVE: Acupuncture is effective for the treatment of chronic musculoskeletal, headache, and osteoarthritis pain. Treatment effects of acupuncture persist over time and cannot be explained solely in terms of placebo effects. Referral for a course of acupuncture treatment is a reasonable option for a patient with chronic pain. (PsycInfo Database Record (c) 2022 APA, all rights reserved)
IMPORTANCE: Acupuncture can help reduce unpleasant side effects associated with endocrine therapy for breast cancer. Nevertheless, comprehensive evaluation of current evidence from randomized controlled trials(RCTs) is lacking.
OBJECTIVE: To estimate the efficacy of acupuncture for the reduction of hormone therapy-related side effects in breast cancer patients.
EVIDENCE REVIEW: RCTs of acupuncture in breast cancer patients that examined reductions in hormone therapy-related side effects were retrieved from PubMed, EMBASE, Web of Science, Ovid MEDLINE, and Cochrane Library databases through April 2016. The quality of the included studies was evaluated according to the 5.2 Cochrane Handbook standards, and CONSORT and STRICTA (Revised Standards for Reporting Interventions in Clinical Trials of Acupuncture) statements.
INTERVENTION: Interventions included conventional acupuncture treatment compared with no treatment, placebo, or conventional pharmaceutical medication. Major outcome measures were the alleviation of frequency and symptoms and the presence of hormone therapy-related side effects. Findings/Results. A total of 17 RCTs, including a total of 810 breast cancer patients were examined. The methodological quality of the trials was relatively rigorous in terms of randomization, blinding, and sources of bias. Compared with control therapies, the pooled results suggested that acupuncture had moderate effects in improving stiffness. No significant differences were observed in hot flashes, fatigue, pain, gastrointestinal symptoms, Kupperman index, general well-being, physical well-being, tumor necrosis factor (TNF), and interleukin (IL).
CONCLUSIONS: Acupuncture therapy appears to be potentially useful in relieving functional stiffness. However, further large-sample trials with evidence-based design are still needed to confirm these findings.
CONTEXT: Most cancer patients suffer from both the disease itself and symptoms induced by conventional treatment. Available literature on the clinical effects on cancer patients of acupuncture, Tuina, Tai Chi, Qigong, and Traditional Chinese Medicine Five-Element Music Therapy (TCM-FEMT) reports controversial results. OBJECTIVES: The primary objective of this meta-analysis was to evaluate the effect of acupuncture, Tuina, Tai Chi, Qigong, and TCM-FEMT on various symptoms and quality of life (QOL) in patients with cancer; risk of bias for the selected trials also was assessed. METHODS: Studies were identified by searching electronic databases (MEDLINE via both PubMed and Ovid, Cochrane Central, China National Knowledge Infrastructure, Chinese Scientific Journal Database, China Biology Medicine, and Wanfang Database). All randomized controlled trials (RCTs) using acupuncture, Tuina, Tai Chi, Qigong, or TCM-FEMT published before October 2, 2014, were selected, regardless of whether the article was published in Chinese or English. RESULTS: We identified 67 RCTs (5465 patients) that met our inclusion criteria to perform this meta-analysis. Analysis results showed that a significant combined effect was observed for QOL change in patients with terminal cancer in favor of acupuncture and Tuina (Cohen's d: 0.21–4.55, <i>P</i> < 0.05), whereas Tai Chi and Qigong had no effect on QOL of breast cancer survivors (<i>P</i> > 0.05). The meta-analysis also demonstrated that acupuncture produced small-to-large effects on adverse symptoms including pain, fatigue, sleep disturbance, and some gastrointestinal discomfort; however, no significant effect was found on the frequency of hot flashes (Cohen's d = −0.02; 95% CI = −1.49 to 1.45; <i>P</i> = 0.97; I² = 36%) and mood distress (<i>P</i> > 0.05). Tuina relieved gastrointestinal discomfort. TCM-FEMT lowered depression level. Tai Chi improved vital capacity of breast cancer patients. High risk of bias was present in 74.63% of the selected RCTs. Major sources of risk of bias were lack of blinding, allocation concealment, and incomplete outcome data. CONCLUSION: Taken together, although there are some clear limitations regarding the body of research reviewed in this study, a tentative conclusion can be reached that acupuncture, Tuina, Tai Chi, Qigong, or TCM-FEMT represent beneficial adjunctive therapies. Future study reporting in this field should be improved regarding both method and content of interventions and research methods. (PsycInfo Database Record (c) 2021 APA, all rights reserved)
Background and objective: Communication between patients and health care practitioners is expected to benefit health outcomes. The objective of this review was to assess the effects of experimentally varied communication on clinical patients’ pain. Databases and data treatment: We searched in July 2012, 11 databases supplemented with forward and backward searches for (quasi-) randomized controlled trials in which face-to-face communication was manipulated. We updated in June 2015 using the four most relevant databases (CINAHL, Cochrane Central, Psychinfo, PubMed). RESULTS: Fifty-one studies covering 5079 patients were included. The interventions were separated into three categories: cognitive care, emotional care, procedural preparation. In all but five studies the outcome concerned acute pain. We found that, in general, communication has a small effect on (acute) pain. The 19 cognitive care studies showed that a positive suggestion may reduce pain, whereas a negative suggestion may increase pain, but effects are small. The 14 emotional care studies showed no evidence of a direct effect on pain, although four studies showed a tendency for emotional care lowering patients’ pain. Some of the 23 procedural preparation interventions showed a weak to moderate effect on lowering pain. CONCLUSIONS: Different types of communication have a significant but small effect on (acute) pain. Positive suggestions and informational preparation seem to lower patients’ pain. Communication interventions show a large variety in quality, complexity and methodological rigour; they often used multiple components and it remains unclear what the effective elements of communication are. Future research is warranted to identify the effective components. (PsycInfo Database Record (c) 2021 APA, all rights reserved)
