Factors Affecting Verbal Agitation in Dementia Patients Living in Nursing Homes, South Korea  [PDF]
Eun Kyung Kim, Heeok Park
Open Journal of Nursing (OJN) , 2018, DOI: 10.4236/ojn.2018.86028
The purpose of this study using secondary data analysis was to identify factors affecting verbal agitation in patients with dementia staying at nursing home. This study is a secondary analysis of an existing original quantitative data set (n = 193). A total of 166 subjects’ data were included in this current study after 27 subjects’ data were excluded from the original data because they did not appear verbal agitation. Multiple regression analyses identified hallucination (β = 0.27), total number of physiologic discomforts (β = 0.19) and pain (β = 0.17) as significant predictors of verbal agitation and these factors explained 27.8% of the variance in the model. The findings of this study showed that hallucination, total number of physiologic discomforts and pain with dementia need to be considered when intervention programs to control verbal agitation in patients with dementia were developed.

Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.211012

The objective of this study was to illustrate the relationship between optimism and defense mechanism in Korean college students. 332 student participants from “A” University in Korea completed questionnaires from the Ewah defense mechanism and optimism measurement tool. This study analyzed the culled data and revealed general patterns of optimism and defense mechanism, as well as patterns based on gender. In addition, the study analyzed differences in defense mechanism, dictated by one’s optimism level. Frequency, percentage, mean, standard deviation, and t-test were analyzed using SPSS 21.0. The results demonstrated that the operating defense mechanism in Korean college students were different for males and females in the categories of show-off, passive aggressive, denial, and identification. However, the level of optimism was identical for both genders. Defensive mechanisms based on optimism levels also varied significantly in controlling, distortion, altruism, humor, sublimation, and rationalization categories.

Open Journal of Nephrology (OJNeph) , 2014, DOI: 10.4236/ojneph.2014.41003

Background: Cardiovascular disease and sudden cardiac death are common in hemodialysis patients. These cardiac complications are often associated with prolonged QTc interval (QTc) and QTc dispersion (QTcd). Subclinical hypothyroidism (SH) can alter autonomic modulation of heart rate and cause increased inhomogeneity of ventricular recovery time. We aimed to evaluate the relationship between thyroid hormone levels and QTc and QTcd in non-diabetic hemodialysis patients. Methods: We enrolled 29 non-diabetic hemodialysis patients without thyroid disease. After each hemodialysis session, a 12-lead ECG was recorded. Before each hemodialysis session, routine laboratory tests and measurement of thyroid hormone levels were performed. Patients were divided into 2 groups according to QTc (group 1 QTc < 430 ms, group 2 QTc ≥ 430 ms). We examined the relationship between QTc or QTcd and thyroid hormone in the respective groups and then compared the results from the 2 groups. Results: The mean age was 54.06 ± 14.72 years and the means of QTc and QTcd were 433.82 ± 22.03 ms, 59.10 ± 28.29 ms, respectively. Homocysteine levels were significant higher in group 2 than group 1 (p < 0.05) and QTcd was comparable between groups. In group 1, QTc and QTcd were not significant correlated with TSH, T3, fT4 and biochemical parameters. In group 2, QTc was significant positively correlated with TSH (p < 0.05) and QTcd was

Eun-Kyung Kim,Jina Choo
International Journal of Environmental Research and Public Health , 2012, DOI: 10.3390/ijerph9010212
Abstract: To explore the prevalence of secondhand tobacco smoke (SHS) exposure of college students at two locations, i.e., on campus and in the home, and to identify factors associated with SHS exposure at each location, a preliminary cross-sectional study was conducted on 1754 nonsmoking students from two universities in Korea. In total, 83.1% were exposed to SHS at least once a week on campus or at home; the average SHS exposure was 3.4 times per week. Specifically, 79.7% and 23.5% were exposed to SHS on campus and in the home, respectively. On campus, SHS exposure was significantly more prevalent in freshmen and sophomore students. In the home, SHS exposure was significantly more prevalent among females, those with smokers in their families, and those who rated their health as poor. SHS exposure was common among nonsmoking college students, with more than two-thirds exposed on campus. The prevalence of SHS exposure was greater on campus than in the home; the factors associated with SHS exposure were location-specific.

Amal Kumar Ghimeray, Ha Youn Lee, Young Hoon Kim, Eun Kyung Ryu, Moon Sik Chang
Technology and Investment (TI) , 2015, DOI: 10.4236/ti.2015.62011
Abstract: In this study, we aimed to observe the cytotoxicity, antioxidant and anti-inflammatory activity of Rhododendron brachycarpum extract (RbE) in RAW 264.7 macrophage cell in vitro and the anti-inflammatory or soothing effect of RbE formulated cream (Multicalm-RHTM) on experimentally induced acute irritated skin in healthy subjects in vivo. In vitro study revealed that RbE significantly inhibited NO and ROS generation in a dose dependent manner without cytotoxicity. In clinical test, Multicalm-RHTM cream siginificantly reduced the SLS-enduced erythema after D5 compared to that of placebo. Overall, it can be concluded that the RbE is a non-cytotoxic, antioxidant and anti-irritant agent which can be used as a potent functional ingredient in cosmetics. Likewise, the in vivo clinical study shows that Multicalm-RHTM cream which contains 3% RbE can be used as an effective skin soothing agent.

BMC Cancer , 2012, DOI: 10.1186/1471-2407-12-164
Abstract: The anti-angiogenic effects of IDR-E804 were examined by assessing the proliferation, migration and capillary tube formation of HUVECs were induced by vascular endothelial growth factor (VEGF) with or without various concentrations of IDR-E804. The inhibitory effect of IDR-E804 angiogenesis and tumor growth in vivo was also investigated in Balb/c mice subcutaneously transplanted with CT-26 colon cancer cells.IDR-E804 significantly decreased proliferation, migration and tube formation of vascular endothelial growth factor VEGF-treated HUVECs. These effects were accompanied by decreased phosphorylation of VEGF receptor (VEGFR)-2, AKT and extracellular signal regulated kinase in VEGF-treated HUVECs. Intratumor injections of IDR-E804 inhibited the growth of subcutaneously inoculated CT-26 allografts in syngenic mice. Immunohistochemistry revealed a decreased CD31 microvessel density index and Ki-67 proliferative index, but an increased apoptosis index in IDR-E804-treated tumors.These data revealed that IDR-E804 is an inhibitor of angiogenesis and also provide evidence for the efficacy of IDR-E804 for anti-tumor therapies.

Kyung Won Park, Eun-Joo Kim, Hwan Joo, Sung-Man Jeon, Seong-Ho Choi, Jay C. Kwon, Byoung Gwon Kim, Jae Woo Kim
International Journal of Clinical Medicine (IJCM) , 2012, DOI: 10.4236/ijcm.2012.35068
Abstract: Background: Mild cognitive impairment (MCI) is a heterogeneous condition with a variety of clinical outcomes, the presence of which correlates with risk of Alzheimer’s disease as well as pre-clinical stages of other dementia subtypes. The aims of this study were to assess the specific patterns of cognitive profiles and to identify changes from baseline to 24 weeks in patients with MCI using detailed neuropsychological testing. Methods: We consecutively recruited 120 MCI patients at baseline according to the Petersen’s clinical diagnostic criteria, who were admitted to the Dementia and Memory Clinics. We analyzed patients who fulfilled both inclusion and exclusion criteria for MCI and classified them into four subtypes according to deficits in major cognitive domains; amnestic MCI single domain (aMCI-s), amnestic multiple domain MCI (aMCI-m), non-amnestic single domain MCI (naMCI-s) and non-amnestic multiple domain MCI (naMCI-m). Four groups of MCI were evaluated by a detailed neuropsychological battery test. Results: 83 patients with MCI at the 24-week follow-up were classified into four subtypes. The most frequent subtype was amnestic multi-domain MCI, with the frequency of MCI subtypes as follows: aMCI-s (n = 21, 25.3%), aMCI-m (n = 53, 63.9%), naMCI-s (n = 5, 6.0%) and naMCI-m (n = 4, 4.8%). In the major cognitive items of the SNSB-D, there were significant changes between the initial and follow-up tests in the domains of language, memory and the fron-tal/executive function (p < 0.05), except for attention, in all MCI patient subtypes. At 24-weeks follow-up, the conversion rate to Alzheimer’s disease was 2.4% (n = 2) from a subtype of amnestic multi-domain MCI. Conclusions: Our study revealed the most frequent subtype of MCI to be multiple domain amnestic MCI, with this subtype having a higher tendency of conversion to Alzheimer’s disease.

Jeongsoo Lee, Kyung-Tai Lee, Sungmin Ahn, Seunghwan Lee, Dajeong Lim, Eun-Seok Cho, Young-Ju Kim, Kyung-Seok Kim, Hailu Dadi, Tae-Hun Kim
Open Journal of Animal Sciences (OJAS) , 2012, DOI: 10.4236/ojas.2012.24030
Abstract: In this study, we analyzed complete mtDNA sequences variation and genetic relationship among taurine, indicine and Bison groups. In total, 107 sequences from different breeds, 45 European (45 Italian), 16 Middle East Asian (seven Iranian and nine Iraqi), 41 Northeast Asian (34 Korean and seven Japanese), two Nellore (Bos indicus) and two American Bison bison (Ame. bison) were obtained from Gen-Bank database. One Korean Hanwoo (Bos taurus) sequence was generated using the SOLiDTM System. In total, 1370 polymorphic sites, representing 8.39% of the complete 107 mtDNA sequences (16,338 bp) were detected and of these, 1186 parsimony informative polymorphic sites were identified. Neighbor-joining tree indicated that Korean, Japanese, Iranian, Iraqi, and Italian cattle were closely related to one another, but are separated from B. Bison. The B. taurus mtDNA polymorphism was greater in the D-loop than in the other regions. The ATP8, ND3, ND5, and ND6 regions were also quite parsimony informative, similar to Cyt b. In addition, this study revealed a distinct genetic difference between Korean cattle and B. indicus.
