Objective: The aim of this research was to investigate the current status and limitations of the clinical use of a pulse tonometry device (PTD). Methods: We searched online medical databases, including Oriental Medicine Advanced Searching Integrated System (OASIS), Research Information Sharing Service (RISS), DataBase Periodical Information Academic (DBpia) and PubMed, for clinical studies of metabolic diseases that used PTD. We selected articles on the clinical application of the PTD but excluded duplicate articles, clinical studies without the PTD, and non-clinical studies. In the first screening, 551 articles were selected. Ultimately, we found 10 articles and classified the articles according to the following diseases: hyperlipidemia, diabetes, overweight and obesity, hypertension, and metabolic disease. Results: Of the 10 selected articles, 4 were focused on hypertension. Two articles were focused on overweight or obesity and two articles were focused on the metabolic disease. Conclusions: This study was the first attempt to conduct a systematic review on clinical studies of metabolic disease using the PTD as a primary outcome. We suggest that the standard of pulse wave parameters and operating procedures for the PTD should be further developed. The results of this study are expected to be used as basic information for the planning and progression of clinical studies of metabolic syndrome using PTD.

The purpose of this review is to examine the performance of attachments used in implant-supported overdenture (IOD) in both clinical and in vitro settings and report the compiled findings, comparisons, and trends in the research literature. Articles published in PubMed on IOD attachment systems and performance were reviewed. Non-original articles were excluded. For each article included, the type of study, number of implants, number of attachment systems, and study outcome were recorded. Of the 283 articles found, 158 met the inclusion criteria. Ninety-four articles were clinical studies and 64 articles were in vitro studies. Studies on retention were the most common for in vitro studies, and four or more attachment systems were compared in most articles with significant differences in outcome. A clinical outcome of one attachment system was most common for clinical studies, while most studies had neutral outcomes overall. Ball attachment was the most commonly tested IOD attachment system. The trend in the literature showed that there is a large discrepancy between the study designs and outcomes between the clinical and the in vitro studies for IOD. Further clinical studies that can validate in vitro research should be encouraged to address this discrepancy between the two areas.

Objectives The goal of this review is to investigate clinical and experimental studies on external application treatment for atopic dermatitis in Korean literature and to propose for the better method of clinical studies in order to seek more effective treatment. Methods Electronic researches were performed with KTKP, OASIS, National Assembly Library, Korean Medicine Database, KISS, DBpia, and KISTI. Results and Conclusions In Twenty six studies, the numbers of clinical and experimental studies are respectively 10 (38.46%) and 16 (61.54%). The numbers of studies that used herbal complex were 20 (76.92%), and out of that, 6 studies had used a single herbal medicine (23.08%). The external application with oriental medicine for the atopic dermatitis used with Phellodendri Cortex (7), Sophorae Radix (6), Scutellariae Radix (6), Lonicerae Flos (5), Coptidis Rhizoma (5) and so on. Among the clinical studies, the 5 studies were double-blind and randomized-controlled study (50%). The numbers of studies that used Hanifin and Rajka Diagnostic Criteria (1980) were 6 (60%), and that used the Diagnostic Criteria in Korean Atopic Dermatitis (2005) were 4 (40%). Among the clinical studies, categories to evaluate of atopic dermatitis are respectively SCORAD Index (80%), Total IgE (80%), Eosinophil count (70%) and so on. All of the clinical studies (100%) showed a statistically significant decline in atopic dermatitis according to the SCORAD Index, Modified SCORAD Index, the Clinic index score. Among the experimental studies, the numbers of studies that used NC/Nga mice were 9 (56.25%), and out of that 5 studies used BALB/c mice (31.25%). Most of the studies (68.75%) used DNCB as allergy inducing materials. The scales for evaluation of atopic dermatitis were Clinical skin severity score, Histopathologic examination, Immunohematologic examination, safety test and so on. In 12 cases (75%) of experimental studies, the IgE level of experimental group showed a statistically significant decline after using external application. In 8 study cases (50%), Clinical skin severity score of experimental group showed a statistically significant decline after using external application.

Objectives : This study reviewed existing studies on clinical examination of Korean medicine to investigate the trends and gaps of existing research on clinical performance examination (CPX) or objective structured clinical examination (OSCE) in Korean medicine education. Methods : We conducted a scoping review according to the five steps suggested by Arksey and O'Malley. Six databases(RISS, OASIS, KMBASE, KISS, ScienceON, and DBpia) were searched and studies published from 2012 to July 15, 2022 were considered. The subjects of the study were limited to domestic studies about OSCE or CPX conducted in Korean medicine education. Results : Among the 25 selected papers, 17 studies implemented OSCE or CPX in practice. Those studies were conducted in 8 clinical departments and 9 of them used standardized patients. All 14 survey studies reported positive answers in satisfaction, efficacy, and self-assessment. OSCE, CPX scoring items were developed by modifying existing tools or developing through expert surveys or through literature review and significant cases. Conclusions : This study is expected to be used as basic data for following studies and promote clinical examination. From now on, the colleges of Korean medicine should proceed research on large-scale students about extended subjects through various research methods to obtain objective results that can be generalized and acquire validity and reliability. In order to promote such research, it is necessary to induce cooperation from institutions related to Korean Medicine and local universities to develop modules, implement, and conduct post-evaluation.

Objectives The goal of this review was to investigate clinical, experimental and literature studies of Korean medicine on atopic dermatitis (AD) of Korean children in Korean medicine literature, seeking for the better research methods for more effective treatments. Methods Electronic investigations were practiced on AKOP (The Association of Korean Oriental Pediatrics, http://www.akop.or.kr) to collect theses which were published by J Pediatr Korean Med. The key word 'Atopy' was used for searching to ensure that every related thesis was collected. The publication date was limited from 1996 to 2016. The selected literatures were assessed mainly according to distributions of study type, publication year, scale, treatment and its efficacy. Results 55 papers were selected from 59 studies. In these collected 55 related theses, there were 29 experimental studies (52.73%), 18 clinical studies (32.73%), 8 review studies (14.55%). In the 29 experimental studies, there were 20 studies (68.97%) using NC/Nga mouse as subjects. The mite antigen was used to trigger AD by 8 studies (27.59%). The studies have been utilizing DNCB and DNFB instead of mite antigen since 2011. All the experimental studies showed that the Korean medicine was effective in AD. In total 18 clinical studies, 3 studies (16.67%) were case reports, only 1 thesis (5.56%) was conducted by case control study and the rest were case series studies. 7 studies (38.89%) of 18 studies diagnosed AD according to Hanifin and Rajka's diagnostic criteria (1980), only 1 study (5.56%) according to the Korean standard and the rest 10 studies (55.56%) didn't mention diagnostic criteria. 12 clinical studies (66.67%) showed efficacy in treating AD. There were 10 studies (55.56%) only employing internal treatments and 1 thesis (5.56%) didn't mention the exact prescription. Naesowhajungtang-kamibang, Saenghyeoryunbue-um were used 3 times (16.67%) as the internal medicine respectively. 5 theses (27.78%) were combined with acupuncture therapy. Hegu (LI4), Sanyinjiao (SP6) were used in 4 theses, and Taichong (LR3), Quchi (LI11), Zusanli (ST36) in 3 theses. The number of acupoints chosen from The Spleen meridian of Foot-Taiyin was the largest. There were 8 review theses. 2 were about the foreign oriental medicine, 3 were about the external medicine or external treatment methods, and 3 other studies were about severity scoring systems, the methodological study in the latest clinical study, overview for pattern and results of herbal medicine-derived AD clinical researches. Conclusions The experimental studies and clinical studies showed the effectiveness of Korean medicine treatments. However, this study still needs improving by conducting more comparative studies and using better research methods, in order to find more effective treatments to improve clinical efficacy.

Objectives: To review and analyze clinical and preclinical evidence of effectiveness, safety, and underlying mechanisms of yokukansan (YKS), a herbal medicine, in alleviating aggression. Methods: Classical records on YKS were searched in the Korean Traditional Medicine Knowledge Database (KTMKD). By searching five electronic databases, prospective clinical studies and preclinical studies of YKS for alleviating aggression/agitation published up to March 30, 2021 were included. Results: Only two classical records on YKS were found from the KTMKD. A total of 11 clinical studies and 15 preclinical studies were found from the five electronic databases. Among 11 clinical studies, seven enrolled patients with dementia and four enrolled patients with other neuropsychiatric disorders. Most clinical studies reported significant improvement in one or more outcomes related to aggression in the YKS group after treatment. Among 15 preclinical studies, all studies except two reported a significant decrease in aggression/agitation-related behavior of YKS or yokukansankachimpihange. Suggested underlying mechanisms of YKS or yokukansankachimpihange for aggression/agitation in these studies included regulation of serotonin receptor, amelioration of abnormal glucocorticoid level related to the hypothalamic-pituitary-adrenal axis, regulation of orexin secretion, amelioration of degeneration in brain cells including glia cells, and suppression of excessive glutamatergic or dopaminergic activity. Conclusions: There were some clinical and preclinical evidence supporting the effectiveness and safety of YKS for alleviating aggression. Given that aggression is the most frequent and destructive symptoms of behavioral and psychological symptoms of dementia, applicability of YKS as a herbal medicine should be further investigated in future high-quality research.

Objectives: The purpose of this systematic review was to understand clinical usefulness of Emotional Freedom Techniques (EFT) on students' mental health. Methods: Ten databases were included to extract clinical studies on effects of EFT intervention with students. Characteristics of selected studies were described, and biases were assessed with Risk of Bias (RoB) or Risk of Bias Assessment for Non-Randomized Studies (RoBANS). Results: A total of 14 clinical trials were extracted for analysis. There were 8 randomized-controlled trials (RCTs), 2 non-randomized-controlled trials (nRCTs), and 4 before-after studies. EFT have significant clinical usefulness in public speaking anxiety, test anxiety, stress, depression, learning related emotions, adolescent anxiety, and eating issues. The risk of selection bias in most studies was high or uncertain. Conclusions: EFT is an effective clinical technique for managing students' mental health issues. However, the included studies have been conducted with relatively poor quality and small sample size. Clinical trials with high quality study design and well-designed EFT education programs are needed to generalize clinical usefulness.

Objectives : This study aimed to investigate both cancer patients' willingness to participate (WTP) in clinical trials and its associated factors. Methods : We searched MEDLINE (PubMed) for studies that had investigated cancer patients' WTP in clinical trials. Search terms included 'willingness to participate', 'cancer' and 'trial'. Studies published within the last five years up to July 26, 2016 were potentially eligible. Results : Of 44 initial hits, 14 studies (12 quantitative and 2 qualitative) were included. Two out of the 14 studies investigated WTP in an acupuncture trial. Study designs, such as WTP measurement methods, investigation settings, and type of cancer, varied. The proportion of participants with a WTP was widely distributed between the studies (median 48.6 %, range 11.1 % to 88.3 %). Factors associated with WTP included various socio-demographic factors, clinical factors, participants' knowledge/attitudes toward clinical trials, travel distance, information from physicians, and trust toward physicians. Conclusion : WTP and its associated factors were variable across the reviewed studies, which might be due to different research methods and contexts. Whether or not common factors associated with cancer patients' WTP in clinical trials exist remains unclear and thus warrants further research.

Objectives : The results from randomized controlled trials on traditional medicine have been negative or ambiguous. The appropriateness of the research methodology started to be questioned. However, the research methodology appropriate for studying traditional medicine has not been well-established. This study aims to explore the appropriate research methodologies for clinical studies on acupuncture. Methods : Clinical researches evaluating the efficacy and effectiveness of acupuncture for back pain were systematically searched and evaluated focusing on research methodology. The acupuncture treatment protocol is evaluated by 9 items which is individual treatment based on diagnosis, combining proximal and distal acupoints, exact location of acupoint, De Qi, adequate stimulation, duration of acupuncture, treatment sessions, treatment interval, and establishing relationship between patients and doctors. Results : Systematic review of acupuncture researches on low back pain suggested that observational studies and pragmatic trials rather than explanatory studies could incorporate these elements. Qualitative studies also could help understanding complex characteristics of acupuncture treatment which could not be evaluated by quantitative studies. Conclusions : In designing clinical researches on acupuncture, various study designs, especially observational study and pragmatic study, should be considered according to research objectives and subjects. The efforts to incorporate the core characteristics of acupuncture practiced in everyday clinical setting are also essential.
