PURPOSE: The objective of this study was to analyze effect size of the intervention studies for posttraumatic growth in patients with cancer. METHODS: A total of 871 studies published between 2000 and 2014 were identified by searching Ovid-Medline, CINAHL, PubMed, Scopus, PsycARTICLES, Cochrane library, RISS, and KISS. 15 studies were selected for inclusion in the meta-analysis. Data were analyzed using the Comprehensive Meta-Analysis (CMA) Ver. 3 program and the effect sizes were shown using Hedges's g score. RESULTS: Intervention studies included 5 studies on Cognitive Behavioral Stress Management (CBSM), 4 studies for Mindfulness-Based Stress Reduction (MBSR), 2 studies for couple-based intervention, and 1 study each for health coaching, building resilience, yoga and painting intervention. The overall controlled effect size was 0.335 (95% CI=0.231, 0.438), using a fixed effects model. The most effective intervention was the couple-based intervention (0.368, 95% CI=-0.146, 0.883), followed by MBSR (0.340, 95% CI=0.172, 0.508) and CBSM (0.314, 95% CI=0.139, 0.490). CONCLUSION: Cancer is one of the most significant traumatic events that affect patients' lives, a few cancer patients have been known to have posttraumatic growth. Therefore it is necessary to consider nursing interventions to increase posttraumatic growth for cancer patients such as couple-based intervention, MBSR and CBSM.

PURPOSE: This study was designed to investigate the difference of oral mucositis in hospitalized cancer patients receiving chemotherapy according to characteristics. METHODS: Data were collected from March 1 to April 25 2012 using questionnaires, and the participants were 177. The Oral Assessment Guide (OAG) by observation and The Oral Mucositis Daily Questionnaire (OMDQ) by self-report were used to measure oral mucositis. The data were analyzed using SPSS 18.0. RESULTS: Moderate to severe oral mucositis measured by OAG observation were 94.9% in hospitalized cancer patients receiving chemotherapy, frequently complaints of mouth and throat soreness measured by OMDQ was 42.4%, and intensity of mouth and throat soreness measured by OMDQ was 0.65 out of 10. There were statistically significant differences in the prevalence of oral mucositis according to nutrition state, frequency of chemotherapy, experience of oral examination, combination treatment, and number of chemotherapeutic agents. CONCLUSION: Many hospitalized cancer patients receiving chemotherapy experienced oral mucositis. Cancer patients receiving chemotherapy with poor nutritional status, more frequent chemotherapy and combination treatments should have a more meticulous oral care. So there needs to be an appropriate assessment tool and prevention protocol for oral mucositis that considers related factors.

Purpose: This study was conducted to develop a predictive model for happiness of students in general high schools.The study was based on the theory of happiness integration and the literature review. Methods: Data were collected using a convenience sample of 231 first and second grade students in five general high schools in D city and K Province. The exogenous variables were optimism as personality factors, parenting attitude, academic stress and friend’s support as happiness. The endogenous variables were self-esteem and resilience as mediating variables, and happiness of students in general high schools. Data collection was done from March 14 to March 28, 2019. The AMOS 22.0 and SPSS programs were used to verify the validity of confirmatory factor analysis and hypothesis models. Results: The factors that have the greatest influence on happiness of high school students are self-esteem and resilience. The explanatory power of happiness by these variables was 98.1%. The individual mediating effect and double mediation effect of these variables were found to be significant. Conclusion As student's optimistic personality, parent's positive parenting attitude, and friend’s support improve student's self-esteem and resilience, ultimately positively affecting high school students' happiness, so it is necessary to consider these factors and try to develop a happiness improvement program.

PURPOSE: The purpose of this study was to identify the level of post-traumatic growth (PTG) and the factors affecting the PTG of cancer survivors. METHODS: Data were collected from 147 cancer patients who were admitted to hospital to two hospitals, P and B city during July and September, 2017 using the PTG Inventory, Multidimensional Scale Perceived Social Support, Event-Related Rumination Inventory, Korean Cancer Coping Questionnaire, Resilience Scale, and Self-Esteem Scale. Data were analyzed using t-tests, ANOVA, Pearson-correlation coefficient, and multiple regression. RESULTS: The mean score for PTG in cancer survivors was 3.20 points. PTG had significant correlation with social support, deliberate rumination, coping, and resilience. Factors that had an influence on PTG in multiple regression were social support (β=0.25, p<001), personal coping (β=0.22, p=.008), resilience (β=0.21, p=.006), recognizing the need for religion (β=0.17, p=.015), religion (β=0.17 p=.011), and deliberate rumination (β=.15, p=.022). These factors explained 60.0% of the variance in the PTG of cancer patients. CONCLUSION: In order to effectively promote PTG of cancer survivors, it is necessary to develop and apply programs that can improve social support, coping (personal), resilience, religion, and deliberate rumination.

BACKGROUND: Infiltration of eosinophils and activated T cells into the airway is a characteristic feature of allergic inflammation such as asthma. IL-4 has been shown to mediate adhesion of eosinophils and T cells to endothelial cells by inducing VCAM-1 expression on endothelial surface. IL-13 shares a number of biologic properties with IL-4. OBJECTIVE: We aimed to investigate the effects of IL-13 on the adhesion of eosinophils to human umbilical vein endothelial cells (HUVEC) and on the expression of VCAM-1 in HUVEC. METHOD: HUVEC was incubated for 24h with IL-13 (10ng/ml), IL-4 (10ng/ml) and TNF-a (10ng/ml). Surface expression of VCAM-1 in HUVEC was detected using irnmuno-cytochemical stain and reverse transcription-polymearse chain reaction (RT-PCR), and the adhesion of eosinophils to HUVEC was quantitated using eosinophil peroxidase (EPO) assay. RESULTS: The VCAM-1 expression on IL-13-treated HUVEC increased more than in the expression on medium-treated HUVEC (p<0.05). The adhesion of eosinophil to IL-13- treated HUVEC also increased more than in the adhesion to medium-treated HUVEC (p<0.05). The VCAM-1 expression was synergistically induced by TNF-a and IL-13 (p<0.05). IL-13 induced VCAM-1 expression and adhesion of eosinophils to HUVEC, similar to IL-4. IL-13 also induced VCAM-1 mRNA expression, with greater expression than with medium and TNF-a(p<0.05). IL-13-induced surface VCAM-1 was associated with expression of mRNA transcripts and adhesion of eosinophils to HUVEC(r=0.89, r=0.93, p<0.05). CONCLUSION: These findings demonstrate that IL-13 stimulates HUVEC to express surface VCAM-1 and has a possible role in promoting VCAM-1/VLA-4 dependent accumulation of eosinophils during allergic and other inflammatory responses.

We report a caae of hepatic and intestinal infestation with paragonimus wewstermani complicating abscess formation. The pathway by which the paragonimus westermani reaehea liver and intestine is not well understood. However, there was possiblity that it may become lodged in other organs that the lung because of polonged larval migrations through the diaphragm or into various sites in the abdomen. The patient, 52-year-old female gave a history of having reyeatedly consumed raw crabs. An x-ray film of the chest showed clear lunga Skin test for paragonimus-westermani was positive. Abdominal ultrasonogram showed enlargement of the liver with multiple hypoechoic lesiona ERCP revealed multiple ie lesions in the right lobe of the liver. Abdaminal CT showed multifocal abscess cavities with slight rim enhancements. Above meetioned diagnostic procedures suggested liver abscess or hepatoma. Then, an exploratory laparotomy was done for a definite diagnosis, Frozen biopsy, from liver and surgically exe mass from ileocecal region revealed extrpulmonary paragnomiasis involving liver and cecum. Thus, the patient was treated with prasiquantel. Three months later, abdominal ultrasonogram demonstrated slight enlargement of the liver but no evidence of abnormal mass like lesions.
