Purpose:
The authors aimed to identify the factors affecting interhospital transfer (“transfer”) of severe pediatric patients who visited to an emergency department (ED).
Methods:
Using the Korean National ED Information System, we analyzed high-acuity patients aged 18 years or younger who visited EDs of local or regional emergency centers nationwide. The high acuity was defined as a Korean Triage and Acuity Scale 1-2. To investigate the factors associated with transfer, a multilevel modeling was selected, examining independent variables at both individual- and hospital-levels with transfer as a dependent variable.
Results:
A model consisting of variables at individual- and hospital-levels showed the factors as follows: mode of arrival(self-transport: odds ratio, 0.48 [95% confidence interval, 0.38-0.61]; other ambulances: 0.41 [0.24-0.71]; compared with firehouse ambulance), visit at 18:00-07:59 (0.75 [0.64-0.88]), intentional injury (1.59 [1.03-2.47]; compared with non-injury), decreased level of consciousness (drowsy: 1.94 [1.33-2.84]; stupor: 4.08 [2.99-5.57]; coma: 1.81 [1.26-2.60]; compared with alert), severe illness diagnosis (1.49 [1.12-1.98]), the number of all beds in EDs (1.02 [1.01-1.04]), and acceptance for treatment (0.92 [0.87-0.98]; with increment of 1%).
Conclusion
This study confirms that both individual-level and hospital-level factors affect the transfer risk of severe pediatric patients in EDs. The study suggests the needs for direct transportation to specialized pediatric treatment facilities, and concentrated support for the pediatric emergency medical centers and pediatric trauma centers.

OBJECTIVES: The objective of this study is to investigate associations between contextual characteristics and unmet healthcare needs in South Korea after accounting for individual factors. METHODS: The present study used data from the 2012 Korean Community Health Survey (KCHS) of 228 902 adults residing within 253 municipal districts in South Korea. A multilevel analysis was conducted to investigate how contextual characteristics, defined by variables that describe the regional deprivation, degree of urbanity, and healthcare supply, are associated with unmet needs after controlling for individual-level variables. RESULTS: Of the surveyed Korean adults, 12.1% reported experiencing unmet healthcare needs in the past. This figure varied with the 253 districts surveyed, ranging from 2.6% to 26.2%. A multilevel analysis found that the association between contextual characteristics and unmet needs varied according to the factors that caused the unmet needs. The degree of urbanity was associated with unmet need due to "financial burden" (odds ratio [OR], 0.53; 95% confidence interval [CI], 0.42 to 0.66 for rural vs. metropolitan), but not unmet need due to "service not available when needed." There were no significant associations between these unmet need measures and regional deprivation. Among individual-level variables, income level showed the highest association with unmet need due to "financial burden" (OR, 5.63; 95% CI, 4.76 to 6.66), while employment status showed a strong association with unmet need due to "service not available when needed." CONCLUSIONS: Our finding suggests that different policy interventions should be considered for each at-risk population group to address the root cause of unmet healthcare needs.

PURPOSE: We evaluated the effect of human parathyroid hormone (hPTH) on the engraftment and/or in vivo expansion of hematopoietic stem cells in an umbilical cord blood (UCB)-xenotransplantation model. In addition, we assessed its effect on the expression of cell adhesion molecules. MATERIALS AND METHODS: Female NOD/SCID mice received sublethal total body irradiation with a single dose of 250 cGy. Eighteen to 24 hours after irradiation, 1x107 human UCB-derived mononuclear cells (MNCs) and 5x106 human UCB-derived mesenchymal stem cells (MSCs) were infused via the tail vein. Mice were randomly divided into three groups: Group 1 mice received MNCs only, Group 2 received MNCs only and were then treated with hPTH, Group 3 mice received MNCs and MSCs, and were treated with hPTH. RESULTS: Engraftment was achieved in all the mice. Bone marrow cellularity was approximately 20% in Group 1, but 70-80% in the hPTH treated groups. Transplantation of MNCs together with MSCs had no additional effect on bone marrow cellularity. However, the proportion of human CD13 and CD33 myeloid progenitor cells was higher in Group 3, while the proportion of human CD34 did not differ significantly between the three groups. The proportion of CXCR4 cells in Group 3 was larger than in Groups 1 and 2 but without statistical significance. CONCLUSION: We have demonstrated a positive effect of hPTH on stem cell proliferation and a possible synergistic effect of MSCs and hPTH on the proportion of human hematopoietic progenitor cells, in a xenotransplantation model. Clinical trials of the use of hPTH after stem cell transplantation should be considered.

Journal of the Korean Society of Emergency Medicine 2020;31(1):88-98
Objective:
The Public Health Disaster Response Team (PHDRT) has been organized by the Community Health Center since 2016 under the National Disaster Response Frame. They are mobilized when a Mass-Casualty-Incident is expected to occur. This study sheds light on the disaster medical system by analyzing the awareness of the PHDRT on the disaster medical management capacity.
Methods:
To develop the questionnaire, a literature review was conducted. The questionnaire was distributed and obtained after inspecting the survey questionnaire filled out by the PHDRT. There were 254 samples. The data were analyzed using descriptive statistics, t-test, ANOVA, and multiple regression.
Results:
Research has proven that the awareness of the disaster medical management capacity was 3.11 (rating 1-5). In detail, organizational capacity received the highest agreement score (3.54±0.84), while the budget and organization management was below the midpoint (2.73±0.83). Significant positive correlations were found between the capacity components, particularly the organizational capacity and cooperation system (r=0.71, P<0.01). The awareness was significantly different according to sex, age, job (type), total career, and task weight. The factors influencing the awareness of disaster medical management capacity included age, total career, and task weight.
Conclusion
The findings from awareness analysis suggest that national and systemic supports, as well as personal efforts, are necessary to strengthen the disaster medical management capacity.

Human infection by Rhodococcus species is rare and mostly limited to immunocompromised hosts such as patients infected with the human immunodeficiency virus (HIV) or organ transplant recipients. The most common strain is R. equi, and the most common clinical presentation is pulmonary infection, reported in 80% of Rhodococcus spp. infections. The central nervous system is an uncommon infection site. We report a case of a patient with pneumonia, brain abscess, and recurrent meningitis caused by Rhodococcus spp. He initially presented with pneumonia with necrosis, which progressed to brain abscess and recurrent meningitis. Rhodococcus spp. was identified from the cerobrospinal fluid (CSF) collected during his fourth hospital admission. Despite prolonged treatment with appropriate antibiotics, meningitis recurred three times. Finally, in order to administer antibiotics directly into the CSF and bypass the blood-brain barrier, an Ommaya reservoir was inserted for administration of 90 days of intrathecal vancomycin and amikacin in conjunction with intravenous and oral antibiotics; the patient was finally cured with this treatment regimen.

PURPOSE: The aim of this study was to examine the effects of long-term endurance exercise and natural fermented vinegar on body composition and cardiopulmonary function of 50-aged postmenopausal women. METHODS: Subjects were divided into four groups (sedentary group, aerobic exercise group, natural fermented vinegar group, and aerobic exercise plus natural fermented vinegar group) to perform natural fermented vinegar intake or aerobic exercise for 8 weeks. Body weight, body composition, cardio-pulmonary function test, and blood concentration of glucose, lipid profiles, aspartate aminotransferase, and alanine aminotransferase were measured. RESULTS: The results showed that natural fermented vinegar or aerobic exercise training for 8 weeks no significantly improved body weight control and body composition. However, natural fermented vinegar plus aerobic exercise training for 8 weeks significantly improved cardiopulmonary function. CONCLUSION: These results suggest that natural fermented vinegar plus aerobic exercise training has a significant effect on anti-fatigue.
