  • This study aimed to compare the disinfectant ability of chlorhexidine (CHX) gel and sodium hypochlorite (NaOCl). Systematic searches were conducted from inception until December 8th, 2022 (MEDLINE/PubMed, Cochrane Library, Web of Science, Scopus, Embase, and Grey Literature databases). Only randomized clinical trials were included. The revised Cochrane risk of bias tools for randomized trials were used to assess the quality of studies. Meta-analyses were performed. The overall quality of evidence was assessed through the Grading of Recommendations Assessment, Development, and Evaluation tool. Six studies were included. Five had a low risk of bias and 1 had some concerns. Three studies assessed bacterial reduction. Two were included in the meta-analysis for bacterial reduction (mean difference, 75.03 [confidence interval, CI, -271.15, 421.22], p = 0.67; I2 = 74%); and 3 in the meta-analysis for cultivable bacteria after chemomechanical preparation (odds ratio, 1.03 [CI, 0.20, 5.31], P = 0.98; I2 = 49%). Five studies assessed endotoxin reduction. Three were included in a meta-analysis (mean difference, 20.59 [CI, -36.41, 77.59], p = 0.48; I2 = 74%). There seems to be no difference in the disinfectant ability of CHX gel and NaOCl, but further research is necessary.

  • The purpose of this study was to evaluate the evidence supporting the effectiveness of moxibustion treatment for osteoarthritis. There were 9 databases used to retrieve randomized controlled trials (RCTs) that used moxibustion as treatment for osteoarthritis. The quality of methodology for the RCTs was assessed using the Cochrane Risk of Bias tool [Review Manager (RevMan) Version 5.3 Windows, The Nordic Cochrane Centre, Copenhagen, Denmark]. The inclusion criteria for this review was met by 27 RCTs. All studies were conducted in China. A 4-week moxibustion treatment period was the most common. EX-LE4 and SP10 and GB34 acupoints were most frequently selected in the treatment of osteoarthritis. The most commonly used evaluation index was the visual analog scale (VAS). All studies, including a meta-analysis showed that moxibustion treatments were statistically significantly effective at treating knee osteoarthritis. However, well-designed randomized RCTs without a high risk of bias should be designed in the future.

  • Objectives : This study aimed to verify the clinical effectiveness of Baduanjin for shoulder pain. Methods : We searched 10 electronic databases (PubMed, EMBASE, Cochrane Library, CAJ, KISS, KISTI, KMBASE, RISS, NDSL, and OASIS) up to May 2020. We included randomized controlled trials (RCTs) using Baduanjin for shoulder pain. The methodological quality of each RCT was assessed using the Cochrane risk of bias tool. Results : As a result of the search, a total of 6 RCTs were eligible for analysis. Of these 6 studies, one applied Baduanjin alone and 5 cases used Baduanjin in combination with other treatments, such as acupuncture or electroacupuncture. Except for 2 studies, descriptive analysis was performed without meta-analysis due to the high level of heterogeneity between studies. A high risk of bias was observed in all studies. Conclusions : When considering the results of the included papers, there was limited information derived on the therapeutic effect of using Baduanjin as a single intervention, but the results showed significant effectiveness when Baduanjin was combined with other oriental interventions, such as acupuncture and electroacupuncture, in the clinical field. Although all RCTs included in the analysis were biased to CAJ and the number was limited, this study was conducted in accordance with the methodological process of systematic literature reviews and revealed the clinical effects of Baduanjin on shoulder pain.

  • Objectives To evaluate the evidence supporting the effectiveness of Bee Venom therapy for traumatic injury. Methods We conducted search across 3 electronic databases (Pubmed, CAJ and Oasis) to find clinical trials that used Bee Venom therapy as treatment for traumatic injury. The methodological quality of RCTs (Randomized controlled clinical trials) were assessed using the Cochrane Risk of Bias (RoB) tool, while NRCTs (Non-Randomized controlled clinical trials) were assessed using the Cochrane Risk of Bias Assessment tool for Non-randomized Study (RoBANS) tool. Results Among 87 articles that were searched, 10 RCTs and 19 NRCTs were finally selected. Among 19 selected studies, all studies showed that Bee Venom therapy has significant effect on traumatic injury. Conclusions Our systematic review found encouraging but limited evidence of Bee Venom therapy for traumatic injury. We recommend clinical trials which compare the effectiveness of Bee Venom therapy with other pharmacopuncture therapies to clarify the effectiveness of Bee Venom therapy from other pharmacopuncture therapies.

  • Objectives: The purpose of this study is to review clinical studies and investigate the efficacy and safety of oriental medicine on memory in menopausal women. Methods: 'menopause', 'memory', 'oriental medicine' were searched on 4 online databases (Cochrane Library, Pubmed, CNKI, OASIS). Randomized controlled trials (RCTs) that evaluated menopausal memory with oriental medicine treatment were included. The methodological quality of each RCT was assessed by using Cochrane risk of bias tool. Results: 8 RCTs were selected among 1067 articles. The overall risk of bias was evaluated as uncertain. 5 studies showed that oriental medicine alone was significant effective, but 1 long-term study with the same oriental medicine did not sustain the effect, and 2 studied were not statistically significant. Conclusions: Oriental medicine can be an effective option for improving memory in menopausal women. but considering the small number and quality of studies, inconsistent and insufficient evidence, further well-designed studies are needed to confirm the efficacy and safety of this treatment.

  • Objectives : The aim of this study is to assess the quantity and quality of randomized controlled clinical trials(RCTs) published in the journal of oriental rehabilitation medicine(JORM). Methods : After searching RCTs from all the articles published in the JORM from the inception(1991) to Oct, 2012, quantity assessment were made on the study design, sample size, main intervention, intervention versus control design and medical condition. Quality assessment were made on the cochrane risk of bias(RoB) check list. Assessment was performed by 2 independent reviewers and disagreement was discussed based on concensus of all authors. Results : Among the 1013 articles, total 59 RCTs were published. First RCT was published in 1994. 49 RCTs were parallel 2-arm designed. Average sample size was 35.1 per study and 16.3 per arm. The most common medical condition is musculoskeletal disease(30.5%). Quality from cochrane RoB was generally low. Conclusions : Though RCTs published in JORM were increasing, the quality remains low. Researchers should make a effort to follow the RoB checklists and improve the quantity and quality of studies.

  • Purpose: The purpose of this study was to examine the effectiveness of non-pharmacological interventions for reducing perioperative anxiety in children undergoing surgery. Methods: A systematic review of randomized controlled trials (RCTs) with the primary outcome of children's perioperative anxiety was conducted. The literature search was performed using various databases, including Cochrane Library, CINAHL, EMBASE, PubMed, and Korean electronic databases with confined to RCTs between 2000 and 2020. A total of sixteen studies were suitable the inclusion criteria and were systematically reviewed. The bias risk of randomized studies was evaluated using Cochrane's risk of bias tool. For the meta-analysis, RevMan 5.4 was used to analyze effect sizes of interventional factors. Results: Finally, twelve RCTs studies were used for meta-analysis. The non-pharmacological interventions implemented to reduce perioperative anxiety in children were therapeutic play, clown therapy and information provision. First, therapeutic play had a significant effect on reducing preoperative anxiety, with an effect size of -1.46 (95% CI=-1.78~-1.14). Second, clown therapy had a significant effect on reducing preoperative anxiety, with an effect size of -0.97 (95% CI=-1.45~-0.49). Finally, the provision of information had a significant effect on reducing preoperative anxiety, with an effect size of -0.75 (95% CI=-0.99~-0.51). Conclusion: This meta-analysis suggests that non-pharmaceutical interventions provide effective methods of reducing perioperative anxiety in children. Therefore, the findings verify evidence that various non-pharmacological interventions are effective means for reducing children's preoperative anxiety.

  • Purpose : Exercise may prevent the worsening of chronic kidney disease (CKD) and progression of cardiovascular diseases in patients with CKD. This review aims to identify the best type of exercise modality and summarizes the beneficial effects of exercise on physical and renal function among older adults with pre-dialysis CKD. Methods : A systematic search of PubMed, Embase, CINAHL, Cochrane Library, Web of Science, SCOPUS, and domestic database was performed for randomized controlled trials (RCTs) assessing the effect of exercise intervention on older adults with pre-dialysis CKD published until February 2023. A random-effects meta-analysis was conducted. The risk of bias was assessed using a Cochrane tool for assessing the risk of bias in RCTs (RoB 2.0). Results : The systematic review included 11 RCTs (n = 591, average age 60.2-76), of which 8 could be included for meta-analysis. Exercise was significant in increasing peak oxygen consumption and knee muscle strength among physical functions, and also in improving glomerular filtration rate among kidney functions. Conclusion : Exercise has beneficial effects on physical and renal function among older adults with pre-dialysis CKD. In the future, it is necessary to verify the effectiveness of exercise by subdividing it by type, intensity, duration, and delivery.

  • Objectives: The purpose of this study was to assess the effects of moxibustion treatment for Cardiac arrhythmia through a systematic review. Methods: Electronic database including Cochrane library, Pubmed, China National Knowledge Infrastructure, Embase, DBpia, and Korean studies Information Service System were searched by combining the keywords such as "arrhythmias", "cardiac arrhythmias", "心律失常", "moxibustion" and "艾灸". Through the searching, 5 randomized controlled trials(RCTs) were included except animal testing and cellular experiment etc. The quality of each RCTs was assessed using the Cochrane risk of bias tool. Results: We included 5RCTs involving 468 participants. Two RCTs compared moxibustion versus conventional treatment, another RCT compared moxibustion plus acupuncture versus conventional treatment, another RCT compared moxibustion plus herbal medicine verus conventional treatment, the other RCT compared moxibustion plus herbal medicine and ointment versus conventional treatment. These studies were evaluated by the efficacy rate of treatments. Studies measured outcomes in efficacy, heart rate, electrocardiogram and symptoms. Each of 5 trials statistically showed a significant differences in efficacy rate. One study reported about side effects and another study reported about complications. The overall risk of bias was unclear in 5 studies. Conclusions: The evidence suggests that moxibustion treatment may help to reduce cardiac arrhythmia, however, it is limited, low-certainty and we cannot rule out benefits or risks with this treatment. High-quality studies that report adverse effects are needed.

  • Objectives: The purpose of this review is to overview the studies of traditional herbal medicine for chronic pelvic inflammatory disease. Methods: We searched relevant studies using seven databases (The Journal of Korean obstetrics & gynecology, National Digital Science Library (NDSL), Research Information Sharing Service (RISS), Oriental Medicine Advanced Searching Integrated System (OASIS), Pubmed, Cochrane, Chinese National Knowledge Infrastructure (CNKI)). Data retrieval was carried out on April 5, 2021 and the papers published from January 1, 2015 to March 31, 2021 were included. The risk of bias was assessed by using Cochrane's risk of bias tool. Results: 524 studies were searched in domestic and foreign databases, and 7 studies were finally selected. In all studies, the treatment group was treated with oral traditional herbal medicine and the control group was treated with western medicine. Although the evaluation index was slightly different for each study, all studies used total efficacy rate index. In all 7 studies, the treatment group was more effective than the control group. Conclusions: Traditional herbal medicine can be an effective option in treating chronic pelvic inflammatory disease. Further high quality studies which include large number should be carried out to confirm the evidence and safety of traditional herbal medicine treatment.
