Is it reasonable emergency department doctor must activate the whole trauma team if they meet the patients who fell above 20 feet?

Objective@#Many trauma centers use their own criteria for major trauma patients, and these criteria are organized according to physiological causes and their related mechanisms. Mechanism related criteria have high sensitivity but low specificity. We confirmed 20 feet as a single factor for trauma team activation criteria. @*Methods@#This study was retrospectively conducted in the Pusan National University Hospital trauma center, which is a level 1 trauma center in Busan. Patients were grouped as group 1, a fall from less than 20 feet; and group 2, a fall from more than 20 feet. We compare the two groups of prognostic factors using logistic regression analysis. @*Results@#The relationship between the height of the fall and the patient’s prognosis showed a positive relationship on the logistic regression analysis. Yet the cut-off value of a 20 foot height showed poor predictive power for the patient’s prognosis. @*Conclusion@#In conclusion, as trauma team activation criteria, a 20 foot height seems to be a reasonable aspect of patients’ clinical prognosis between above 20 feet and below 20 feet. Yet it seems to be controversial as a cut-off value. Thus, more studies will be needed to identify a specific height for trauma team activation.

Seroprevalence of Surface Antigen and Antibody Positive Rate of Hepatitis B Virus in Low-Income People

BACKGROUND: The purpose of this study was to provide health screening for low-income people and early diagnosis and treatment for health risk factors and diseases for the promotion of the health of vulnerable people. This study was also aimed toward the implementation of a comprehensive cancer health screening system to improve quality of life.METHODS: This study was conducted in 1,546 subjects aged >40 years who underwent free cancer screening between February and December 2017 in the Jeollanam-do region. In the first, we performed a survey HBsAg, Anti-HBs, 54 peoples with hepatitis B abnormalities were checked to secondary screening, HBeAg/Anti-HBe, HBV DNA.RESULTS: The overall HBsAb total seropositivity rate was 59.8% (924/1,546), and the HBsAb total seronegativity rate was 40.2% (622/1,546). The HBsAg total seropositivity rate was 3.8% (58/1,546) overall, 1.7% (26/1,546) in the men, and 2.1% (32/1,546) in the women. The HBeAg seropositivity rate was 11.1% (6/54) in the second hepatitis B screening.CONCLUSION: We found that the positivity and negativity rates of HBsAb (Anti-HBs) were similar to those reported in other studies, but the positivity rate of HBeAg was slightly higher in the second hepatitis screening. In future surveys, factors must be analyzed, including an additional investigation of the related health risk factors to confirm the factors that affect diagnosis and initial evaluation results.

Development and Effects of Social Learning Theory Based Eye-Health Program for Preschoolers

PURPOSE: The purpose of this study was to develop an eye-health program based on social learning theory (EPST) of preschoolers and evaluate its effectiveness. METHODS: A nonequivalent control group pre-post test design was utilized and 141 six-year-old preschoolers and their parents participated (experimental group=69, control group=72) in the study. The EPST in this study included eye-health education and eye exercises. Attention, memory, replay, motivation, reinforcement, and self-efficacy were used as interventional strategies. To examine the effectiveness of EPST, proficiency in eye-health activities, refractive power, and visual acuity were measured before and after the intervention. Data were analyzed with SPSS WIN 21.0 using the Shapiro-Wilk test, χ2-test, Mann-Whitney U test and Wilcoxon signed rank test. RESULTS: Following the intervention, eye-health activities, refractive power, and visual acuity significantly improved in the experimental group compared to the control group. CONCLUSION: The results of this study suggest that EPST is effective in improving eye-health activities, refractive power, and visual acuity in preschoolers, and its wider implementation in educational institutions will promise improved eye-health among preschoolers.
