Background:
and Purpose Treatments for neuromyelitis optica spectrum disorder (NMOSD) such as eculizumab, ravulizumab, satralizumab, and inebilizumab have significantly advanced relapse prevention, but they remain expensive. Rituximab is an off-label yet popular alternative that offers a cost-effective solution, but its real-world efficacy needs better quantification for guiding the application of newer approved NMOSD treatments (ANTs). This study aimed to determine real-world rituximab failure rates to anticipate the demand for ANTs and aid in resource allocation.
Methods:
We conducted a nationwide retrospective study involving 605 aquaporin-4-antibody-positive NMOSD patients from 22 centers in South Korea that assessed the efficacy and safety of rituximab over a median follow-up of 47 months.
Results:
The 605 patients treated with rituximab included 525 (87%) who received continuous therapy throughout the follow-up period (median=47 months, interquartile range=15–87 months). During this period, 117 patients (19%) experienced at least 1 relapse. Notably, 68 of these patients (11% of the total cohort) experienced multiple relapses or at least 1 severe relapse.Additionally, 2% of the patients discontinued rituximab due to adverse events, which included severe infusion reactions, neutropenia, and infections.
Conclusions
This study has confirmed the efficacy of rituximab in treating NMOSD, as evidenced by an 87% continuation rate among patients over a 4-year follow-up period. Nevertheless, the occurrence of at least one relapse in 19% of the cohort, including 11% who experienced multiple or severe relapses, and a 2% discontinuation rate due to adverse events highlight the urgent need for alternative therapeutic options.

Journal of Korean Academy of Community Health Nursing 2018;29(4):530-538
PURPOSE: This study tried to identify changes in family burden after the introduction of the long-term care insurance and to examine the factors influencing subjective and objective caring burden and depression of family caregivers of elders receiving home-based long-term care. METHODS: Data were collected from 203 family caregivers of elders from August 1 to 31, 2015 using questionnaires. They were analyzed in descriptive statistics, t test, ANOVA test, and multiple regression analysis. RESULTS: The mean score of depression was 7.24, which suggested mild depression level. The subjective family burden was 2.71 and the objective burden 3.04. The factors affecting depression included subjective burden (t=5.08, p < .001), objective burden (t=2.80, p=.006), time of elderly care per day (t=−3.61, p < .001), caregiving duration (t=3.33, p=.001), age (t=3.13, p=.002), family relationship (t=2.48, p=.014), and economic status (t=1.99, p=.047). CONCLUSION: The family burden was most important influencing factor on caregiver's depression. Therefore, services and supports to alleviate caregivers' burden in the home-based care should be added to long-term care.

Korean Journal of Health Promotion 2016;16(1):1-10
BACKGROUND: According to the 2013 statistics, The prevalence rate of depression of women was twice compare to man. Especially, about 53% of depression patients were women over age 40. So this study was conducted to analyze whether women's depression is influenced by their socio-demographic characteristics, life stress, and social support. METHODS: This study was a descriptive survey, and data were collected during the period from the 1st to 31st of August in 2015, using a self-reporting questionnaire from 196 women aged between 40 and 60 who were sampled from an urban area through convenient sampling. RESULTS: First, among the sub-factors of life stress, health-related & role conflict stress were highest. And life stress was higher when social support was low. Second, social support was higher when exercise was done regularly. Lastly, the results of structural equation modeling analysis showed that life stress and social support had a significant effect on depression. Life stress had a significant direct effect on social support, and social support had a significant direct effect on depression. Life stress had an indirect effect on depression through the medium of social support, and their explanatory power was R2=0.68 and R2=0.64, respectively. CONCLUSIONS: This study confirmed that depression was in a very close relationship with life stress and social support. This finding suggests that future health policies for managing middle-aged women's depression should focus on reducing life stress and reinforcing their social support.

PURPOSE: This study attempted to investigate the prevalence and related factors of Clonorchiasis among five major riverside residents in South Korea. METHODS: This study is descriptive research, nationwide survey, and the subjects are 23,492 residents selected by convenience sampling. Data collection was conducted between March 1 and June 30, 2011, and stool collection and questionnaire survey were conducted by affiliated public health centers in 38 cities and Gun's. RESULTS: The prevalence rates of Clonorchiasis in the five major riversides were as follows: the Guem River 15.2%; the Nakdong River 11.9%; the Seomjin River 10.9%; the Han River 5.7%; and the Yeongsan River 3.9%. The prevalence rates were shown to be significantly high among people who had highly frequent experiences of eating and cooking freshwater raw fish, were diagnosed with liver and/or biliary tract diseases, and drank less than once a month. CONCLUSION: These results suggest that it is necessary to improve awareness of Clonorchiasis and provide intensive public health education for the riverside residents. And the target groups should be set up by reflecting the characteristics of at-risk groups, and it is necessary to prepare customized strategies for prevention and management of Clonorchiasis.

Asian Nursing Research 2016;10(3):182-188
PURPOSE: The purpose of this study was to find the relationship and conceptual model of discrimination, stress, support, and depression among the elderly in South Korea. METHODS: This was a cross-sectional descriptive study involving 207 community-dwelling elders. Data were collected through questionnaires from May 5 to May 31, 2014 in community senior centers, and analyzed using descriptive statistics, t test, analysis of variance, Scheffè test, and structural equation modeling. RESULTS: There were significant effects of discrimination on stress, support on stress and stress on depression. Moreover, there were two significant indirect effects observed between discrimination and depression, and between support and depression. For each indirect effect, the mediating factor was stress. Additionally, there was no direct effect between discrimination and depression or support. CONCLUSIONS: This study found that social support and discrimination had indirect effects on depression through stress. More specifically, decreased stress led to a reduction of depression. Therefore, social support based on a thorough understanding of stress is very important for caring elderly who are depressive.
