Factors Affecting Job Satisfaction of Immigrant Korean Nurses.

PURPOSE: An increasing number of foreign-born nurses are working in the United States. Nurses' job satisfaction is a critical issue for quality patient care. The purpose of this study was to examine factors affecting the job satisfaction of immigrant Korean nurses. DESIGN: We used a cross-sectional mailed survey design. A convenience sample (n = 105) of members of the Greater New York Korean Nurses Association currently working or had previously worked in the United States completed the questionnaires. We used hierarchical regression to test the effects of acculturation and life satisfaction on job satisfaction. RESULTS: Most participants were female (n = 98, 93.3%) aged 27 to 70 years (mean = 52.27 years, SD = 10.67). In the regression model, life satisfaction, self-esteem, and perceived stress predicted job satisfaction (F = 5.127, p < .001) and explained 44.5% of the variance of job satisfaction. DISCUSSION AND CONCLUSION: U.S. nurses need to gain insight into factors influencing job satisfaction in Korean nurses to promote retention and quality care.

Social Network Analysis of Elders' Health Literacy and their Use of Online Health Information.

OBJECTIVES: Utilizing social network analysis, this study aimed to analyze the main keywords in the literature regarding the health literacy of and the use of online health information by aged persons over 65. METHODS: Medical Subject Heading keywords were extracted from articles on the PubMed database of the National Library of Medicine. For health literacy, 110 articles out of 361 were initially extracted. Seventy-one keywords out of 1,021 were finally selected after removing repeated keywords and applying pruning. Regarding the use of online health information, 19 articles out of 26 were selected. One hundred forty-four keywords were initially extracted. After removing the repeated keywords, 74 keywords were finally selected. RESULTS: Health literacy was found to be strongly connected with 'Health knowledge, attitudes, practices' and 'Patient education as topic.' 'Computer literacy' had strong connections with 'Internet' and 'Attitude towards computers.' 'Computer literacy' was connected to 'Health literacy,' and was studied according to the parameters 'Attitude towards health' and 'Patient education as topic.' The use of online health information was strongly connected with 'Health knowledge, attitudes, practices,' 'Consumer health information,' 'Patient education as topic,' etc. In the network, 'Computer literacy' was connected with 'Health education,' 'Patient satisfaction,' 'Self-efficacy,' 'Attitude to computer,' etc. CONCLUSIONS: Research on older citizens' health literacy and their use of online health information was conducted together with study of computer literacy, patient education, attitude towards health, health education, patient satisfaction, etc. In particular, self-efficacy was noted as an important keyword. Further research should be conducted to identify the effective outcomes of self-efficacy in the area of interest.

The epigenetic silencing of LIMS2 in gastric cancer and its inhibitory effect on cell migration.

Recent finding has shown that LIMS2 (also known as PINCH2) functions as a natural regulator of the LIMS1-ILK-parvin complex formation and is associated with cell spreading and migration via integrins at focal adhesions. Here, we report for the first time the epigenetic silencing of LIMS2 in gastric tumors. Downregulation of LIMS2 was detected in 91% (10 of 11) of gastric cancer cell lines by real-time quantitative RT-PCR and 80% (8 of 10) of the LIMS2-downregulated cell lines were associated with CpG island hypermethylation at a 5'-upstream region of LIMS2. Furthermore, LIMS2 was restored in its non-expressing cell lines after treatment with 5-Aza-dC and/or trichostatin A. Loss of expression of LIMS2 was also detected in 53% (51 of 96) of primary gastric tumors. This decrease in expression level significantly correlated with an increase of the CpG island hypermethylation. In addition, the methylation status in any normal-appearing gastric tissues was gradually increased in an age-dependent manner, suggesting that the positive methylation in normal-appearing gastric mucosa can be due to 'field cancerization effect' as an early event in gastric carcinogenesis. Moreover, the transient transfection of LIMS2-siRNA significantly stimulated cell migration in gastric cancer cells but had no effects on cell growth. These results suggest that the frequent inactivation of LIMS2 by epigenetic alteration in gastric cancer may be important in tumor progression events, such as invasion and metastasis. Thus, LIMS2 may be useful as a molecular biomarker and a therapeutic target by increasing its expression and activity in gastric cancer.
