  • Silanized-hydroxypropyl methylcellulose (Si-HPMC)/phase transformed calcium phosphate (PTCP) composites are prepared to purpose application of injectable bone cements with enhanced biocompatibility. The crystal structure and chemical state of the synthesized PTCP and Si-HPMC as solid and liquid phase of the composite cements were measured by XRD and FT-IR. The handling and mechanical properties of cements were measured by injectability tests and three-point bending tests. The in-vitro mechanical properties, XRD, and SEM results of bone cements were showed that enhanced hardening behavior was an inherent function of bone cements after in-vitro test. The cytotoxicity result of bone cements also was showed enhanced biocompatibility. Therefore, these injectable cements had potential be used as calcium phosphate cements for biomedical applications.

  • Purpose: The purpose of this study is to identify effects of the variables of Health Action Process Approach (HAPA) Model on physical activity. Methods: This study has conducted a systematic literature review and meta-analysis. Sixteen articles were searched through electronic databases (PsycINFO, PubMed, CINAHL, Web of science, Science Direct, RISS, KMBASE, KoreaMed, KISS, DBpia) and additional journals from 2000 to July, 2017. To estimate the effect size (ES), the meta-analysis of the studies was performed by using Comprehensive Meta-Analysis programs. Results: The overall effect size of the variables of HAPA on physical activity was median (ES=.28). Of the core variables of HAPA model, action control (ES=.43) showed the largest effect size, followed by coping self-efficacy (ES=.31) and planning (ES=.31).Additional variables were identified as preparatory behavior (ES=.39) and past physical activity (ES=.24). Through the moderator effect analysis, the effect size was higher in the volitional phase than in the motivational phase, and higher in the healthy group than in the patient group. The higher the proportion of males and the lower the age, the larger the effect size. Conclusion: This finding shows empirical evidence that all core variables of the HAPA model are useful for predicting physical activity. We propose the use of the HAPA model to develop physical activity promotion intervention.

  • Purpose: Extracorporeal life support (ECLS) is a term used to describe a number of modalities including extracorporeal membrane oxygenation (ECMO) to support cardiac and/or pulmonary systems. The purpose of this study is to review the available evidence regarding the effect of ECLS in patients with acute poisoning. Methods: Electronic literature searches with PubMed, Embase, Cochrane library, and KoreaMed were conducted for identification of relevant studies addressing ECLS in treatment of acute poisoning. The literature search was conducted by two investigators in March, 2016 with publication language restricted to English and Korean. The toxic substance, technique of ECLS, and final outcome of each case were analyzed. Results: The final analysis included 64 articles including 55 case reports. There were no articles classified according to a high level of evidence such as randomized trial and prospective cohort study. ECLS treatment was used in the management of patients poisoned with 36 unique substances. Venovenous ECMO was performed in 4 cases. Among the reported cases, 10 patients died despite treatment with ECLS. Conclusion: Evidence supporting ECLS for patients with acute poisoning is inadequate. However, many case reports suggest that early consideration of ECLS in poisoned patients with refractory cardiac arrest or hemodynamic compromise refractory to standard therapies may be beneficial.

  • Purpose: The purpose of this study was to evaluate the usefulness of intravenous lipid emulsion as well as adverse events in acute poisoning patients. Methods: Literature was accessed through PubMed, EMBASE, Cochrane library, Web of science, and KoreaMed. All forms of literatures relevant to human use of intravenous lipid emulsion for acute poisoning were included. Cases reports or letters without description of clinical outcomes for each case were excluded. The literature search was conducted by two investigators in March, 2015, with publication language restricted to English and Korean. The effect, onset time, and adverse event of lipid emulsion and final outcome of each case were analyzed. Results: Eighty-one published articles were included, excluding articles whose title and abstract were not relevant to this study. No articles were classified as high level of evidence. Sixty-eight case reports were identified, consisting of 25 local anesthetics and 43 other drugs, such as tricyclic antidepressants and calcium channel blockers. Although most cases described significant clinical improvements, some of them showed no beneficial effect or worsening of clinical course. Several adverse events including hyperamylasemia and laboratory interference were reported. Conclusion: Although there were many case reports illustrating successful use of lipid for various drug poisonings, the effect cannot be estimated due to significant possibility of publication bias. Therefore, lipids might be considered in severe hemodynamic instability resulting from lipophilic drug poisoning, however further studies should follow to establish the use of lipid as the standard of care.

  • Purpose: This study was conducted to evaluate the clinical efficacy of pharmacologic treatment of amatoxin poisoning patients. Methods: Literature was accessed through PubMed, EMBASE, Cochrane library, KoreaMed, KISS and KMBASE. Studies relevant to human use of pharmacologic therapy including silymarin, penicillin and N-acetylcysteine (NAC) for amanita poisoning were included. Case reports, letters, editorials and papers with insufficient information were excluded. Comparison of clinical outcomes (especially mortality and liver transplantation rate) in each study was analyzed. Results: The final analysis included 13 retrospective studies. None of these studies showed direct comparisons of individual agents. Among 12 studies comparing silymarin vs penicillin, eight showed clinical superiority of silymarin. Among eight studies comparing silymarin with NAC, six showed clinical superiority of silymarin. Among seven studies of NAC vs penicillin, five showed clinical superiority of NAC. Conclusion: This systematic review suggested that clinical superiority of various pharmacological agents used to treat amatoxin poisoning is debatable. Nevertheless, the available evidence suggests it is reasonable to consider combinations of multiple agents for patients with amanita poisoning. Further studies are required to establish a treatment regimen for amanita poisoning.

  • Purpose: Unbalanced diets and decreased physical activity have contributed to increased prevalence of obesity and metabolic syndrome in adolescents. We have performed a systematic review and data analysis to examine the association between dietary pattern and metabolic syndrome risk factors in adolescents. Methods: We searched the PubMed and BioMedLib databases for appropriate articles published during the past 10 years and selected 6 articles. The studies reviewed applied factor analysis or cluster analysis to extract dietary patterns. For data analysis, we examined the association between dietary patterns and the prevalence of metabolic syndrome risk factors using data of 3,168 adolescents (13 to 18 years) obtained from 4 consecutive Korean Nutrition Health and Nutrition Examination Surveys (1998, 2001, 2005, and 2007 to 2009). Results: Our systematic review confirmed that western dietary patterns are positively associated with metabolic syndrome risk factors such as obesity and elevated triglycerides, while traditional dietary patterns were negatively associated. Data analysis found that the number of adolescents aged 16 to 18 years who had "Rice & Kimchi" dietary pattern decreased, while the number having western dietary patterns increased during the 1998 to 2009 time frame. There were no changes in the dietary patterns in adolescents aged 13 to 15 years. The risk of elevated serum triglycerides and reduced serum high density lipoprotein cholesterol was high in the "Rice & Kimchi" dietary pattern compared to the other dietary pattern groups. Conclusion: Because adolescents' dietary patterns are changing continuously and have long-term effects, further studies on the dietary patterns of adolescents and their health effects into adulthood are necessary.

  • Background: This study aimed to evaluate the mechanical, biological, and esthetic stability of a zirconium abutment according to evidence-based dentistry. Main text: An electronic search was performed. Domestic studies were found using the keywords "zirconia abutments" and "zirconium abutment" in KMbase, KoreaMed, and the National Assembly Library, and international studies were found using the same keywords in PubMed. All identified studies were divided by evidence level from the viewpoint of the research type utilizing the evidence-based review manual. A total of 102 domestic studies (with Korean language) were found, and 9 of these studies were selected. In these nine studies, 3 had evidence level 3 and 6 had evidence level 4. A total of 97 international studies (with English language) were found, and 19 were selected. Among these 19 studies, 5 had evidence level 2 and 7 had evidence level 3, whereas the remainder had evidence level 4. According to the studies, zirconium abutments are mechanically, biologically, and esthetically stable, but the evidence level of these studies is low, and the follow-up duration is no longer than 5 years. Conclusions: All examined studies verified the mechanical stability of zirconium abutments for a period no longer than 5 years. Therefore, a long-term clinical observation is needed. Zirconium abutments are thought to be biologically stable, but they are not superior to titanium abutments. As the esthetic stability of such abutments had a low evidence level in the studies that examined here, a much higher evidence level is needed.
