  • The quality of subgroup analyses (SGAs) in chronic non-cancer pain trials is uncertain. The purpose of this study was to address this issue. We conducted a comprehensive search in MEDLINE and EMBASE from January 2012 to September 2018 to identify eligible trials. Two pairs of reviewers assessed the quality of the SGAs and the credibility of subgroup claims using the 10 criteria developed by Sun et al. in 2012. The associations between the quality of the SGAs and the studies' characteristics including risk of bias, funding sources, sample size, and the latest impact factor, were assessed using multivariable logistic regression. Our search retrieved 3,401 articles of which 66 were eligible. The total number of SGAs was 177 of which 52 (29.4%) made a subgroup claim. Of these, only 15 (8.5%) were evaluated as being of high quality. Among the 30 SGAs that claimed subgroup effects using an appropriate method of performing interaction tests, the credibility of only 5 were assessed as high. None of the subgroup claims met all the credibility criteria. No significant association was found between the quality of SGAs and the studies' characteristics. The quality of the SGAs performed in chronic pain trials was poor. To enhance the quality of SGAs, scholars should consider the developed criteria when designing and conducting trials, particularly those which need to be specified a priori.

  • Combining multiple classifiers to obtain improved performance over the individual classifier has been a widely used technique. The task of constructing a multiple classifier system(MCS) contains two different Issues how to generate a diverse set of base-level classifiers and how to combine their predictions. In this paper, we review the characteristics of existing multiple classifier systems : Bagging, Boosting, and Slaking. For document classification, we propose new MCSs such as Stacked Bagging, Stacked Boosting, Bagged Stacking, Boosted Stacking. These MCSs are a sort of hybrid MCSs that combine advantages of existing MCSs such as Bugging, Boosting, and Stacking. We conducted some experiments of document classification to evaluate the performances of the proposed schemes on MEDLINE, Usenet news, and Web document collections. The result of experiments demonstrate the superiority of our hybrid MCSs over the existing ones.

  • Purpose is to systematically examine the factors related to patient safety nursing of nursing university students in a convergent and complex aspect and to identify the effect size through meta-analysis. The research method used PRISMA(Preferred Reporting Items for Systematic Reviews and Meta-Analyses). Medline, Embases, CINAHL, DBpia, Research Information Service System (Riss), and Korean Studies Information Service (Kiss) were used, while overseas databases were searched using MeSH terms and Emtrees. The search term was [(patient safety or patient harm or safety management) and (students, nursing)] or [(patient safety or patient harm or safety management) and (education, nursing, graduate)].The research found that nursing performance, knowledge, attitude, self-confidence, recognition, and cognition were found to be relevant factors in the order of confidence, attitude, recognition, and knowledge.

  • This study aimed to investigate the latest trends in the relationship between atopic dermatitis(AD) and psychological factors(PF) and to examine it in korean medicine. We searched MEDLINE for this analysis with the title "atopic dermatitis" AND ("psychology" OR "psychological" OR "mental" OR "emotion" OR "anxiety" OR "depression") in recent 5 years and searched OASIS on the title "atopy" OR "psychology" OR "emotion" from 2002 to 2017. We selected 23 papers on MEDLINE, 7 papers on OASIS. In western medicine, Stress causes changes in the adrenal nerves, endocrine, and immunological mechanisms and exacerbates dermatitis, which is explained by HPA axis and sympathetic nerve axis, neurogenic inflammation, and cholinergic signals. In Korean medicine, Stress(神) exacerbates AD by affecting the five organs, especially the heart(心), causing inflammation(火熱). We studied the link between AD and PF in Western and Korean medicine. More research is needed in the future.

  • The purpose of this study is to explore practical methods of interlibrary loan system, linked with information retrieval system. The process and current status of interlibrary loan was investigated and analyzed at medical libraries in this study. In order to find the way of utilizing data from information retrieval and document request at the same time, the author tries to develop a way of linking PubMed, Union Catalog and ILL system. This study shows that hit record of information retrieval was saved in type of MEDLINE, XMLJSGML and reused for document delivery services. It seems to be efficient that the maintenance of Union Catalog was managed by all of member libraries, and data were retrieved at server and client side at once. In addition, it was found that user information can be checked by the IP and ILL system can be used for requested document by the saved result.

  • PURPOSE: This study analyzed the trends and characteristics of shoulder rehabilitation research through keyword analysis, and their relationships were modeled using text mining techniques. METHODS: Abstract data of 10,121 articles in which abstracts were registered on the MEDLINE of PubMed with 'shoulder' and 'rehabilitation' as keywords were collected using python. By analyzing the frequency of words, 10 keywords were selected in the order of the highest frequency. Word-embedding was performed using the word2vec technique to analyze the similarity of words. In addition, the groups were classified and analyzed based on the distance (cosine similarity) through the t-SNE technique. RESULTS: The number of studies related to shoulder rehabilitation is increasing year after year, keywords most frequently used in relation to shoulder rehabilitation studies are 'patient', 'pain', and 'treatment'. The word2vec results showed that the words were highly correlated with 12 keywords from studies related to shoulder rehabilitation. Furthermore, through t-SNE, the keywords of the studies were divided into 5 groups. CONCLUSION: This study was the first study to model the keywords and their relationships that make up the abstracts of research in the MEDLINE of Pub Med related to 'shoulder' and 'rehabilitation' using text-mining techniques. The results of this study will help increase the diversifying research topics of shoulder rehabilitation studies to be conducted in the future.

  • The availability and use (citedness) of Korean medical journals are measured based on the bibliometric data of 82 journals evaluated by the Korean Association of Medical Journal Editors between 1997 and 1999. A Korean medical journal is held on the average by one half of Korean medical libraries investigated. Only 10 journals (12.2%) are covered in any of 36 abstract and index databases in the field of medicine searchable through DIALOG. The journal self-citation rate is 3.402%. 1.092% of papers are cited at least once by SCI journal papers within 3 years after publication. The average SCI impact factor of Korean medical journals is 0.111, However, the impact factor of MEDLINE or SCISearch journals is 10 times higher. The results show that the Korean medical journals are not easily available domestically and internationally. They are hardly cited by Korean colleagues or by foreign scholars either.

  • To verify the association between GSTM1/GSTT1 gene polymorphisms and susceptibility to autoimmune diseases in Asian population. 18 published reports cited in EMBASE, Google, KISS, MEDLINE and PubMed up to December 2015 were collected for a meta-analysis. The GSTM1/GSTT1 polymorphism for null and present type were analysed separately. The significant association was found between the GST polymorphism and autoimmune diseases in an overall population (GSTM1, OR=1.334, 95% CI=1.137-1.567, p=0.000; GSTT1, OR=1.212, 95% CI=1.012-1.452, p=0.037). Asian population showed the significant association of GSTM1 in the autoimmune diseases, especially vitiligo and atopic dermatitis but non-significant association of GSTT1 in RA and SLE. The GSTM1 null and the GSTT1 present type showed the association with autoimmune diseases in Asian population. The null type frequency of the combination of GSTM1-GSTT1 polymorphism in autoimmune diseases in Asian population was higher than that of the control group. This result indicated that null type of GSTM1-GSTT1 combination can be a risk factor of autoimmune diseases in Asian population.

  • The purpose of this study was to determine the trends of research on the effects of psychosocial intervention related to children with epilepsy. 454 articles were retrieved from databases (Ovid-MEDLINE, EMBASE, PubMed, CINAHL, The Cochrane library, KMbase, and Koreamed), and 7 articles met our criterias. Interventions were classified into four categories: education; counseling; cognitive-behavioral therapy; and physical activity. The target outcomes of the interventions were quite diverse. Each intervention showed some benefits for epilepsy-related health outcomes, but each study had methodological weaknesses, including incomplete information, poorly defined or validated outcome measures, small sample sizes, and design limitations.

  • The purpose of the this study was to provide objective evidence through a systematic review and meta-analysis regarding the effects of self-management in knee osteoarthritis. Articles published between 1999 and 2013 from periodicals indexed Ovid Medline, CINAHL, PubMed, RISS, KISS and other databases were selected, using the following key words: Osteoarthriti* OR OA, self-(management OR care OR help). A selection of 11 studies(7 randomized controlled trials and 4 quasi-experimental interventions that were used were exercise, education, massage and self-help group. As a result of mera-analysis, self-management significantly effected pain, physical function, activities of daily living, and self-efficacy. In particular, self-management showed great effect on ADL, and moderate effect on pain and physical function. Based upon these result, it is necessary to develop a standardized self-management program for knee osteoarthritis patients.
