ABSTRACT
Background@#This study was conducted to identify the association between sleep duration and suicidal ideation among farmers in Korea. @*Methods@#We used Safety for Agricultural Injuries of Farmers cohort data collected from September 2015 to June 2018, which was an agricultural survey on the health and behaviors of adult farmers in Jeju island, Korea. @*Results@#A total of 964 participants were included in the analysis, and 3.7% of them were identified with having suicidal ideation. The frequencies of average daily sleep duration of 8 h (long sleep) were 24.4%, 70%, and 5.6%, respectively. Multivariate analyses revealed that short sleep duration was significantly associated with suicidal ideation compared with normal sleep duration (odds ratio = 2.49, 95% confidence interval = 1.07–5.77). @*Conclusion@#Our findings suggest that short sleep duration in farmers result in higher suicidal ideation. Because individuals who have suicidal ideation often commit suicide, careful monitoring is required to prevent suicide in farmers with short sleep duration.
ABSTRACT
Arachnoid web is a very rare disease that occurs when the normal flow of cerebrospinal fluid is disturbed due to abnormal formation of the arachnoid membrane in the arachnoid space. Consequently, symptoms appear in the form of various myelopathies, such as loss of strength and sensation in the upper and lower extremities, or bladder control disorders. In general, surgical treatment can be considered if symptoms are exhibited. Arachnoid web requires a high consideration of appropriate diagnosis and treatment methods. However, due to its extremely rare occurrence in actual clinical practice, it is difficult to differentiate from other diseases such as herniated intervertebral disc or subdural tumor causing spinal myelopathy. This would effectively lead to a completely different direction of treatment. To date, there have been no case reports of Arachnoid web in Korea, except for collecting and reporting the focal anterior displacement of the thoracic spine, which is a similar lesion in the spinal cord. This article therefore provides information through case reports and literature review.
ABSTRACT
Objective@#This study aimed to determine whether there is a difference in mortality and medical resource utilization between geriatric (aged ≥65 years) and super-geriatric patients (aged ≥80 years) with traumatic brain injury (TBI). @*Methods@#We obtained comprehensive data (demographics, injury characteristics, injury severities, and outcomes) of geriatric and super-geriatric TBI patients from an emergency department-based injury surveillance system database from 2011 to 2016. Multivariate logistic regression analysis was performed to compare the mortality and nonroutine discharge (NRDC) status between both groups. @*Results@#Among 442,533 TBI patients, 48,624 were older than 65 years. A total of 48,446 patients (37,140 geriatric and 11,306 super-geriatric) without exclusion criteria were included in the final analysis. Both overall in-hospital mortality (adjusted odds ratio, 1.88; 95% confidence interval [CI], 1.28 to 2.74; P=0.001) and NRDC (adjusted odds ratio, 1.35; 95% CI, 1.07 to 1.71; P=0.011) were significantly higher in the super-geriatric group. In the stratified analysis, there were no significant differences in NRDC rate for all stratifications of treatment timing (emergency department vs. ward admission), but mortality remained to be significant for all stratifications. @*Conclusion@#Super-geriatric TBI patients showed a significantly higher risk-adjusted overall mortality and more inadequate medical resource utilization than did geriatric TBI patients. However, super-geriatric patients were more likely to undergo NRDC after admission; thus, further research about age-related health inequalities is needed in the treatment of super-geriatric patients.

ABSTRACT
Background@#We aimed to investigate the prevalence of low back pain (LBP) and its associated agricultural work-related, biomechanical factors among this population. @*Methods@#We analyzed initial survey data from the Safety for Agricultural Injury of Farmers cohort study involving adult farmers in Jeju Island. The prevalence of LBP was calculated with associated factors. @*Results@#In total, 1,209 participants were included in the analysis. The overall prevalence of LBP was 23.7%. Significant associations for LBP were the type of farming activity, length of farming career, prior agricultural injury within 1 year, and stress levels. Multivariate logistic regression analysis revealed three biomechanical factors significantly related to LBP: repetitive use of particular body parts; the inappropriate posture of the lower back and neck. @*Conclusions@#Some occupational, and biomechanical risk factors contribute to LBP. Therefore, postural education, injury prevention education, and psychological support will be needed to prevent LBP.
ABSTRACT
OBJECTIVE: This study aimed to achieve expert consensus for the evaluation of Emergency medical system operation fund (EMSOF) support projects using the Delphi method in Korea. METHODS: The Delphi study was performed in June 2018. Experts who are members of the policy committee of the Korean Society of Emergency Medicine (KSEM) participated in the study. Respondents were asked to express their level of agreement of appropriateness for the following 6 categories for 21 projects: project contents, amount of support, indicators, performance, overall evaluation, and need to maintain. With a possible score of 9 points, the project categories were classified into 3 groups, inappropriate, moderate and appropriate, based on the median score of the respondents' ratings in each question. RESULTS: Sixteen of the 18 policy committee members participated in the survey. Their average professional work years were 8.2 years. All 21 projects were evaluated as appropriate for content. Amount of support and indicators were evaluated as moderate. Only 5 out of the 21 projects were evaluated as having appropriate indicators. No projects were evaluated as ineffective. Comprehensive evaluation of the projects was evaluated as moderate, and no project was evaluated as inappropriate in fund support. CONCLUSION: Overall, the contents of the EMSOF assistance project were rated high; however, there was a disagreement on the amount of support and evaluation indicators for each project. The results of this study are expected to be used as basic data to improve the use of EMSOF.

OBJECTIVE: The aim of this study was to investigate the interpersonal violence (IPV) epidemiology and mortality according to the violence victim-perpetrator relationships. METHODS: A retrospective cross-sectional study was done using the comprehensive data of the emergency department (ED)-based Jeju Injury Surveillance System from all EDs in Jeju Island. The demographic characteristics of the victims, the types of perpetrators (spouse, family members, acquaintance, and stranger), injury characteristics and clinical outcomes from the injury were collected. The IPV epidemiology was reported by descriptive statistics. Multivariate Poisson regression was used to analyze the association between the mortality and violence victim-perpetrator relationships. RESULTS: Among the 23,508 violent injury patients enrolled from January 1, 2008, and December 31 of 2016, 19,879 (84.6%) were analyzed; 16 (0.08%) died at the ED. The types of perpetrators were the spouse (10.1%), family members (3.9%), acquaintances (43.4%), and strangers (42.7%). The mortality of the violence victims was increased significantly by the spouse (incidence rate ratio [IRR], 6.336; P=0.043) or family members (IRR, 11.089; P=0.016) compared to strangers. On the other hand, there was no difference between the acquaintances and strangers. CONCLUSION: The epidemiology and mortality of IPV were associated with the violence victim-perpetrator relationships. Therefore, it is necessary to develop and apply prevention programs considering these differences, particularly for intimidate/ family violence because of its high fatality.

PURPOSE: Providing proper emergency medical services (EMS) for domestic or international visitors to popular destinations is becoming increasingly important. Jeju Island is the most visited spot in South Korea. The number of people visiting Jeju Island has increased every year, and this was over ten times the registered population on Jeju Island. The purpose of this study was to describe EMS use behavior and to estimate demand for EMS for visitors on Jeju Island. METHODS: A retrospective observational study was conducted on Jeju Island, with 580,000 citizens. EMS is a fire-based system with a single tiered intermediate service level by a single centralized dispatch center, 29 ambulances, and approximately 130 EMS providers. We collected all ambulance run-sheet data, which included comprehensive information as well as patients' address identification, monthly number of visitors, and census data of Jeju Island from January, 2010 to December, 2012. RESULTS: Among 90,674 EMS transports, 7,209 (8%) were excluded because of unknown address of patients, and of all 83,456 (100%) patients using EMS, 9,733 (12%) were visitors and 73,732 (88%) were residents. The percentage of females was higher for visitors than residents (45% vs. 43%, p<0.001) and the mean age was younger in visitors (38+/-19 vs. 54+/-22, p<0.001). Injury was much higher for visitors than residents (63% vs. 38%, p<0.001). The estimated monthly number of EMS use per 10,000 people was 3.7 (95% CI 3.5 to 3.9) in visitors and 35.7 (95% CI 34.9 to 36.5) in residents, with a ratio of 0.104 (95% CI 0.099 to 0.108). The trend of ratio by year was not significant (p=0.630). The correlation between monthly EMS use in visitors and monthly number of unregistered population was significant (Pearson's correlation 0.844). CONCLUSION: Determining EMS use behavior and the demand of EMS in visitors is a critical task. Our results are of interest in preparing and providing the provision of EMS for visitors.

Multinucleated giant cells (MGCs) are a prominent characteristic of granulomatous inflammation including tuberculosis. The present study was performed to investigate the characteristics and distribution pattern of intracellular and cell surface glycoconjugates of the MGCs in human pulmonary tubercles using lectin histochemistry. The cytoplasmic staining patterns could be divided into three groups. First, VVL, LCA and SBA showed intense reactivity in the great majority of the MGCs. Second, BS -I, DBA, WGA, PNA, ECL, PHA -L and PHA -E also showed positive staining in the cytoplasm of many MGCs, but the reaction patterns were not uniform. Third, the other group (BS -I - B4 and UEA -I) exhibited very weak or no staining in the cytoplasm. With regard to the membranous staining, the lectin binding patterns could be divided into two groups. First, WGA, ECL, PHA -L & PHA -E showed intense membranous staining. Second, the other lectins (BS -I, BS -I -B4, DBA, VVL, LCA, PNA, SBA and UEA -I) did not show any membranous staining. There was no significant difference in lectin binding patterns between the two types of MGCs. Our results demonstrated the characterization of glycoconjugates expressed in the MGCs in human pulmonary tubercles.
