Purpose: The purpose of this study was to identify the influencing factors on Predictors of depression in disability with hearing impairment. Methods: Data from the secondary data (The 2014 National Survey of the Disabled Persons) were obtained, and subjects of hearing impaired 190,323 who responded certainly yes or no answer to the question were selected. x2 and t-test analysis were used to compare the potential predictors between depression and non-depression group. Significant factors were entered in Logistic regression analysis to identify the predictors of depression. Results: The prevalence of depression was 5.7% (n=10,769) in disability with hearing impairment. Life satisfaction, go out alone, subjective economic status, medical examination, level of disability, disability aids from social services, satisfaction of leisure activities, awareness of discrimination, disability awareness in healthcare provider, hearing aids use and age were shown significant differences in depression and non-depression. Life satisfaction (OR=11.04 [10.20~11.96]) and go out alone (OR=3.52 [3.22~3.83]) were found to be the most influential risk factors for depression in disability with hearing impairment. Conclusion To prevent depression in disability with hearing impairment, affected factors such as life and leisure activities satisfaction, level of physical dependence, economic status, hearing aids, and social inequalities should be monitored.

Objective: We aimed to determine the characteristics of in-hospital cardiac arrest (IHCA) patients, as well as the factors influencing survival to discharge and good neurologic outcome. Methods: We examined patients who experienced IHCA from January 1, 2011, to December 31, 2013, in Soonchunhyang University Seoul Hospital. They were divided into a survival group and non-survival group. The patient characteristics, including age, sex, comorbid disease, arrest time, arrest location, witnessed arrest, monitoring, arrest cause, arrest rhythm, and cardiopulmonary resuscitation (CPR) duration, were compared between the groups. Moreover, we assessed the factors associated with survival to discharge and good neurologic outcomes by using multivariate logistic regression analysis. Results: In total, 453 patients of IHCA were observed. The comorbidities in the survival group included neurologic disease (P < 0.001), arrhythmia (P = 0.001), and myocardial infarction (P = 0.032), pneumonia (P = 0.016). Other characteristics included cardiac arrest at daytime (P = 0.032), cardiogenic arrest cause (P = 0.019), and CPR duration < 15 minutes (P < 0.001). The factors associated with survival to discharge included comorbid neurologic disease (odds ratio [OR], 2.191; P = 0.031), arrhythmia (OR, 3.027; P = 0.009), pneumonia (OR, 3.243; P = 0.002), and CPR duration < 15 minutes (OR, 9.638; P < 0.001). The factors influencing good neurologic outcomes included age < 65 years (OR, 3.158; P = 0.007), comorbid disease as arrhythmia (OR, 4.921; P = 0.001), pneumonia (OR, 4.551; P = 0.001), hypotension (OR, 4.264; P = 0.021), and CPR duration < 15 minutes (OR, 6.652; P = 0.001). Conclusion The factors influencing survival to discharge and good neurologic outcomes among IHCA patients included comorbidities, arrest cause, and CPR duration.

Purpose: The aims of this systematic review were to identify the study protocol of Virtual Reality Therapy (VRT) and review the effect of VRT among patients with Post-Traumatic Stress Disorder (PTSD). Methods: This review followed the guideline of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A systematic literature search was conducted using 12 electronic databases including gray literature with no limit of publication year. Search terms included relevant terms regarding “PTSD”, “trauma”, and “VRT”. Among 265 studies extracted through PRISMA, 20 studies were selected and evaluated for quality assessment using the Risk of Bias tool of Cochrane’s collaboration. Results: The majority of the literature focused on combat veterans and war situations (95%).Usually, each session usually took 60~120 minutes of VRT in 10~20 sessions for 5~10 weeks. The VRT equipment and contents were individually designed considering patients’ traumatic experiences. Most of the studies reported the positive effects associated to reduced levels of PTSD (80%) and related symptoms, such as, depression (45%) and anxiety (25%). Conclusion Based on our findings, further studies are required to evaluate VRT in people with PTSD, after improving study design and standardizing protocols.

Amitraz is acaricidal and insecticidal pesticide used worldwide to control ticks and mites in plants and animals. Amitraz poisoning is characterized by clinical toxidrome such as central nervous system, respiratory depression, bradycardia, hypotension, hypothermia, and hyperglycemia. Toxic mechanism of amitraz is mainly alpha2-agonistic function and poisonings may occur by any route. Such clinical symptoms and signs of acute amitraz poisoning were possible to be thought as a toxidrome of acute organophosphate poisoning. We reported a 68-year-old woman that initially was misdiagnosed as acute organophosphate poisoning on the ground of symptoms and signs of mental change, respiratory depression, bradycardia, and hypotension. However, the serum level of pseudocholinesterase level at emergency room admission was within normal level and a vacant bottle of amitraz pesticide was founded around the yard of the patient. The patient was totally recovered from acute amitraz poisoning 2 days later after mechanical ventilation and conservative cares including atropine injection.

PURPOSE: This study was done to develop and validate a measure to evaluate the Korean version of psychological insulin resistance (K-PIR) in patients with diabetes in Korea. METHODS: Items were initially generated from literature reviews and interviews with 19 patients with diabetes. The content validity of the items was evaluated by experts. Participants were 424 patients with diabetes recruited through convenience sampling. A cross-sectional survey was designed for item-analysis, exploratory factor analysis with principal axis factoring, and confirmatory factor analysis. Cronbach's alpha was calculated to measure the internal consistency. RESULTS: For the 24 items of the Korean version of psychological insulin resistance, six items were eliminated because of low correlation with the other items. Exploratory factor analysis with 18-item showed that two factors (psycho-cognitive factor and supportive factor) explained 41.8% of the variance, and the factor structure of K-PIR model had a good fit. Internal consistency of K-PIR with 18 items revealed good reliability. CONCLUSION: The findings show that the K-PIR is reliable for measuring the psychological resistance to insulin therapy for Korean patients with diabetes. However, further study is needed to evaluate the validation because the proportion of variation of K-PIR was low in this study.

PURPOSE: The aim of this study was to determine the relationship between the injury severity and pain intensity according to age in patients with extremity injuries. METHODS: Adult patients with an extremity injury who visited the emergency department (ED) from June 1, 2016 to November 31, 2016 were analyzed retrospectively. The major injury was defined as structural damage below the muscle layer, such as muscle, ligament, and bone. Minor injury group and major injury group were separated according to this definition. The relationship of age and pain score assessed with the numerical rating scale (NRS) with the injury severity was analyzed. RESULTS: Of a total of 1,441 patients, the number of patients with a minor and major injury was 854 (59.3%) and 587 (40.7%), respectively. The proportion of patients aged 65 and older was 6.1% and 25.7% in the minor and major injury group, respectively. Age and NRS scale showed significantly positive associations with the injury severity (p < 0.001). In all NRS scores, the overall proportion of major injuries in the older age group was higher than that in the younger age group. Regardless of the younger ( < 65 years) or older (≥65 years) age group, the NRS score was positively related to the injury severity (young age group [odds ratio, 3.944]; older age group [odds ratio, 5.754]). CONCLUSION: The pain intensity is positively related to the severity of injury regardless of age. The pain intensity is the important factor of a patient assessment and treatment in the emergency department.

PURPOSE: The aim of this study was to compare the effects of breast milk (BM) feeding with those of maternal cow milk (CM) restriction and extensively hydrolyzed CM formula feeding on the duration of CM allergy as well as changes in specific immunoglobulin E (IgE) levels in infants with CM allergy. METHODS: Children diagnosed with CM allergy before 12 months age and BM fed were included retrospectively. CM allergy was diagnosed by CM specific IgE over 0.35 kU/L and 1) obvious clinical symptoms, 2) a suspicious history with positive provocation test, or 3) CM specific IgE over the 95% positive predictive value and subsequent documented report of clinical symptoms. The patients were classified into three groups by feeding regimen: BM group, extensively hydrolyzed formula (eHF) group, or mixed feeding (MF) group. Analysis of the groups regarding the duration of food allergy and changes in CM specific IgE was then performed. RESULTS: Forty-six children were included. Twenty-four children were in the BM group, 13 children were in the eHF group, and 9 children comprised the MF group. Thirteen patients reached tolerance. The means of the tolerance age were 69.7+/-5.4 months in the BM group, 36.6+/-4.6 months in the eHF group, and 38.2+/-7.9 months in the MF group. The survival curves of tolerance showed significant difference among the three groups (P=0.04). CM specific IgE levels measured at a second time period were 9.6 kU/L (interquartile range, 3.6-44.2) in the BM group, 2.0 kU/L (1.0-18.0) in the eHF group, and 4.8 kU/L (0.2-10.4) in the MF group (P=0.04). CONCLUSION: Feeding regimen influences the duration of CM allergy. Exclusively BM-fed children achieved tolerance later than eHF-fed children. Prospective and randomized controlled studies are required.

PURPOSE: In elderly and patients with underlying diseases, mortality rate is increased when compared to rib fractures which occurred in other patients. Because there is a shortage of emergency physicians or real-time consultation with radiologists in many countries, it is necessary to receive a formal image reading remotely from an expert. We suggested the use of iPad in X-ray reading and compared the diagnostic validity of iPad, which was highly portable, with that of liquid crystal display (LCD) monitor. METHODS: Fifty four X-ray cases of rib fracture and 54 cases without rib fracture were randomized and reviewed by 10 emergency physicians. A total of 108 cases were divided 1st to 54th and 55th to 108th. Two sessions were separated with a four-week interval. If the reviewer interpreted the 1st to 54th with iPad, they did 55th to 108th with LCD monitor. Reviewers reported the presence of rib fracture, the number of fractured ribs, and diagnostic confidence of 5-scale. RESULTS: The interobserver agreement among reviewers in LCD and iPad was 0.551, 0.524 in Fleiss-kappa value. The intraobserver agreement between tools for each reviewer was 0.410-0.859 (Mean=0.628+/-0.150). Reviewers showed sensitivity over 0.810 regardless of the tool; 0.810- 0.966 (Mean=0.879+/- 0.054) in LCD, 0.828-1.000 (Mean=0.898+/-0.052) in iPad. The specificity was 0.520- 0.860 (Mean=0.750+/-0.117) in LCD and 0.560-0.880 (Mean=0.708+/-0.111) in iPad. Therefore, remote consultation of X-ray by iPad with a specialist was possible with minimized temporal and spatial limits in the emergency room. CONCLUSION: In our study, there was no statistical difference in the diagnosis of rib fracture by X-ray via iPad or LCD. Therefore, remote consultation of X-ray by iPad with a specialist in the emergency room was possible, with temporal and spatial limits by iPad.

OBJECTIVES: Despite the importance of the protection of patients' health information in clinical settings, little is known about the awareness of this concept in nursing students due to the lack of a suitable measurement tool. Hence, this study attempted to redevelop the Patients' Health Information Protection Awareness Scale, and evaluate its construct validity and reliability for nursing students. METHODS: A cross-sectional descriptive study was conducted. Nursing students who were in their 3rd and 4th year were recruited from 10 universities in Korea to assess the construct validity, and 30 experts (27 nurses and 3 faculty members) participated in the content validation process. RESULTS: The content validity assessment indicated that 23 items were ideal. The assessment of construct validity using exploratory factor analysis revealed three factors: communication, management, and referrals. They together accounted for 54.1% of the variance in scale scores. The three-factor scale had good fit in the confirmatory factor analysis. Scale reliability was confirmed, with a Cronbach's alpha of 0.94 for all items. CONCLUSIONS: This study was the first attempt to redevelop the Patients' Health Information Protection Awareness Scale for student nurses. The 23-item scale was shown to be a reliable and valid tool. It facilitates the assessment of nursing students' awareness of patient information protection. Academic nursing programs and health organizations can use its scores to implement adequate education plans to safeguard information in nursing students.
