OBJECTIVES: Refugees from North Korea are at risk of a range of mental health problems, posing urgent problems to their care. A review of research on mental health prevalence and services can indicate directions for further study. METHODS: The authors administered a Delphi survey to 16 professionals who are working for North Korean refugees, including professors and field workers. The collected data was analyzed by descriptive statistics including mean and standard deviation and verified with content validity ratio. RESULTS: The results are as follows: 1) The most serious problem in the research area is the importance of quantitative research rather than qualitative for North Korean refugees, who are often very negative and uncooperative with questionnaires. 2) There is a great need to develop competence of mental health professionals who are working for North Korean refugees. 3) Most participants agreed to the necessity of longitudinal study to define the factors facilitating successful adaptation among North Korean refugees. CONCLUSION: The following are our recommendations: 1) Appropriate measurements for North Korean refugees need to be developed reflecting their uniqueness. 2) Research of North Koreans has inherent selection bias. 3) It is essential to provide primary education on mental health to North Korean refugees.

Background: Needle insertion for spinal anesthesia using the Taylor approach is challenging as the L5-S1 space is difficult to locate from the surface anatomy. In this study, we suggest the use of three-dimensional (3D) pelvis computed tomography (CT) to assist anesthesiologists in locating the needle insertion point. By comparing the success rate of 3D pelvis CT-assisted Taylor approach to that of other approaches in the existing literatures, we suggest this technique as an alternative method for subarachnoid block in the L5-S1 space. Methods: In this retrospective observational study, we reviewed the records of hip arthroplasty using the 3D pelvis CT-assisted Taylor approach. An imaginary guidance line was created from the intersection point of the midline and intercristal line on the posterior view of the 3D pelvis CT to the ideal skin insertion point for Taylor approach. The primary outcome was the success rate. The secondary outcomes included the angle between the intercristal line and the guidance line, and the length of the guidance line and the distance between the ideal needle insertion point and the L5-S1 space. Results: We reviewed the records of the 276 patients who underwent hip arthroplasty using 3D CT-assisted Taylor approach. In this cohort, the 3D CT-assisted Taylor approach in L5-S1 subarachnoid block failed in only 25/276 patients. The success rate of 3D CT-assisted Taylor approach was 90.9%. Conclusions A 3D pelvis CT-assisted Taylor approach of spinal anesthesia can be an alternative method for subarachnoid block in the L5-S1 space with an acceptable success rate.

Background: This study aimed to investigate the association between e-cigarette (EC) use and development of acute severe pneumonia in the Korean population using a national database. Methods: We conducted a retrospective analysis using linkage of data between the Korean National Health and Nutrition Examination Survey (KNHANES) and the National Health Insurance Service (NHIS) administrative claims database. The primary endpoint of this study was development of severe pneumonia requiring hospital admission according to EC use during the study period. The secondary endpoints were in-hospital mortality, intensive care unit (ICU) admission, ventilator care, and days of hospital stay. Results: The final analysis included 28,950 individuals, of which 578 (2.0%) were EC users.EC users were younger and more often male than non-EC users. The EC users showed higher level of education and household income and had fewer comorbidities. Severe pneumonia was noted in 37 of 28,372 non-EC users (0.13%), but there were no occurrences of severe pneumonia in EC users. The incidence of pneumonia occurrence was not different between the two groups (P = 1.000). Conclusions Since e-cigarette or vaping use-associated lung injury (EVALI) is most likely included in acute severe pneumonia occurring within 3 months of EC use, it is considered that there might be no EVALI patients in Korea during the investigation period. A large-scale, prospective study is necessary to evaluate the association between EC use and acute lung injury.
