Background. Knee osteoarthritis (KOA) seriously affects people’s life. Therefore, it has already become a worldwide health concern. Moxibustion has a significant clinical effect on KOA. This systematic review and meta-analysis is performed to renew previous studies and strictly evaluate the quality of RCT and thus test the effect and safety of moxibustion for KOA. Objective. To evaluate the effectiveness and safety of moxibustion treatment for alleviating pain and improving lower limb function for patients with KOA. Materials and Methods. CNKI (1979∼2019), CBM (1979∼2019), VIP (1989∼2019), WF (1998∼2019), PubMed (1966∼2019), Embase (1980∼2019), Cochrane Library, and Web of Science (1900∼2019) were all retrieved by a computer from their inception to June 02, 2019, replenished by manual retrieval of relevant bibliographies. Randomized controlled trials (RCTs) were included if moxibustion was compared to western medicine or negative control (placebo moxibustion or no treatment or UC) for treating KOA. The primary outcomes were the total effect and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC scale). The secondary outcomes include VAS, Symptom score, Lysholm score, and Lequesne score. RCTs were collected, and the quality of evidence was evaluated by using the Jadad scale and Cochrane risk assessment tools. We used RevMan5.3.0 software for meta-analysis. Results. A total of 39 RCTs were included, including 3293 patients. In the assessment of the quality, the evidence differs from low to high based on the Cochrane Bias Evaluation Tools and Jadad scale. Fourteen trials were of high quality, ten were of moderate quality, and 15 were of low quality. Therefore, the quality of the included studies was moderate. In this study, there were 66.67% of the literature, and only 17.95% of the literature correctly reported randomized grouping and allocation of hidden information, respectively. In adverse reactions, only 13 trials included were reported in the study. The main adverse reactions of moxibustion are burns and blisters, whereas the western medicine group was in epigastric discomfort. As for the total effective rate, the meta-analysis of 27 RCTs showed a significant effect of moxibustion VS western medicine (RR = 1.20, 95% CI = 1.16 to 1.25, I2 = 45%, P=0.007); as for the WOMAC scale, the subgroup meta-analysis of 13 trials showed that there was a statistically significant effect of moxibustion VS western medicine (MD = −11.08, 95% CI = −11.72 to −10.44, I2 = 98%, P<0.00001) and 2 trials on moxibustion VS negative control (MD = −8.38, 95% CI = −12.69 to −4.06, I2 = 0%, P=0.77); as for the VAS score, the meta-analysis of 6 trials showed that there was a significant effect of moxibustion VS western medicine (MD = −2.12, 95% CI = −2.30 to −1.93, I2 = 98%, P<0.00001); as for the symptom score, the meta-analysis of 7 trials showed that there was a significant effect of moxibustion VS western medicine (MD = −0.81, 95% CI = −1.24 to −0.37, I2 = 50%, P=0.06); as for the Lysholm score, the meta-analysis of 5 trials showed that there was a significant effect of moxibustion VS western medicine (MD = 7.61, 95% CI = 6.04 to 9.17, I2 = 95%, P<0.00001); and as for the Lequesne score, the meta-analysis of 3 trials showed that there was a significant effect of moxibustion VS western medicine (MD = 3.29, 95% CI = 2.93 to 3.65, I2 = 99%, P<0.00001). Conclusion. Moxibustion treatment for KOA is more effective than the positive control (western medicine) or negative control (placebo moxibustion or no treatment or UC), and there were fewer adverse reactions to moxibustion. Due to the universally low quality of the eligible trials, it still needs further large-scale and high-quality randomized controlled trials to verify the effectiveness and safety of moxibustion in the treatment of KOA.

BACKGROUND: Neuropathic pain (NP) encompasses many difficult-to-treat disorders. There are few head-to-head, comparative, randomized controlled trials (RCTs) of drugs for NP in different analgesic categories, or of different drugs within a category, despite many placebo-controlled RCTs for individual agents. Well-designed head-to-head comparative trials are an effective way to determine the relative efficacy and safety of a new drug.OBJECTIVE: To perform a systematic review of head-to-head RCTs of oral analgesics in NP.METHODS: A systematic review of RCTs involving NP patients was performed, of which head-to-head comparative trials were selected. Reference lists from published systematic reviews were searched. These studies were rated according to the Jadad scale for quality.RESULTS AND CONCLUSIONS: Twenty-seven such trials were identified. Seventeen were comparisons of different analgesics, and 10 were of different drugs within an analgesic class. Important information was obtained about the relative efficacy and safety of drugs in different categories and within a category. Some significant differences between active treatments were reported. Trial inadequacies were identified. More and improved head-to-head RCTs are needed to inform clinical choices.

Oncology Treatment

Cancer affects more than 19.3 million people and has become the second leading cause of death worldwide. Chemo- and radiotherapy, the most common procedures in these patients, often produce unpleasant treatment-related side effects that have a direct impact on the quality of life of these patients. However, innovative therapeutic strategies such as probiotics are being implemented to manage these complications. Thus, this study aimed to evaluate the efficacy of probiotics supplements as a therapeutic strategy in adult oncology treatment-related side effects. A systematic review of randomized controlled trials was conducted in PubMed, Scielo, ProQuest and OVID databases up to and including January 2021, following the PRISMA guidelines. The quality of the included studies was assessed by the Jadad Scale. Twenty clinical trials published between 1988 and 2020 were included in this review. Seventeen studies (85%) revealed predominantly positive results when using probiotics to reduce the incidence of treatment-related side effects in oncology patients, while three studies (15%) reported no impact in their findings. This study sheds some light on the significance of chemotherapy and radiotherapy in altering the composition of gut microbiota, where probiotic strains may play an important role in preventing or mitigating treatment-related side effects.

Acupoint Stimulation

Objective. To investigate the effect of auricular acupoint stimulation on overweight and obese adults. Methods. We searched databases including PubMed, EMBASE, Allied and Complementary Medicine Database, National Knowledge Infrastructure, and the PerioPath Index to Taiwan Periodical Literature. The modified Jadad scale was used to assess study quality. We investigated the effect of auricular acupoint stimulation on anthropometric measurements. Results. Eighteen randomized controlled trials (RCTs) were included in our systematic review. Thirteen RCTs were pooled in a meta-analysis that revealed a significant reduction in body weight (BW) with a mean difference (MD) of -1.21 kg and a 95% confidence interval (CI) from -1.94 to -0.47 with a heterogeneity of I2 = 88%. Significant decreases in body mass index (BMI; MD: -0.57 kg/m2; 95% CI -0.82 to -0.33; I2 = 78%), body fat (BF; MD: -0.83%; 95% CI -1.43 to -0.24; I2 = 0%), and waist circumference (WC; MD: -1.75 cm; 95% CI -2.95 to -0.55; I2 = 87%) were also revealed. Conclusions. This meta-analysis shows that auricular acupoint stimulation improves physical anthropometric parameters including BW, BMI, BF, and WC in overweight and obese adults. These methods are less effective on hip circumference and waist-to-hip ratio.

Abstract. In randomized controlled trials (RCTs), a common strategy to increase power to detect a treatment effect is adjustment for baseline covariates. However, adjustment with partly missing covariates, where complete cases are only used, is inefficient. We consider different alternatives in trials with discrete-time survival data, where subjects are measured in discrete-time intervals while they may experience an event at any point in time. The results of a Monte Carlo simulation study, as well as a case study of randomized trials in smokers with attention deficit hyperactivity disorder (ADHD), indicated that single and multiple imputation methods outperform the other methods and increase precision in estimating the treatment effect. Missing indicator method, which uses a dummy variable in the statistical model to indicate whether the value for that variable is missing and sets the same value to all missing values, is comparable to imputation methods. Nevertheless, the power level to detect the treatment effect based on missing indicator method is marginally lower than the imputation methods, particularly when the missingness depends on the outcome. In conclusion, it appears that imputation of partly missing (baseline) covariates should be preferred in the analysis of discrete-time survival data.
