Purpose: The National Emergency Medical Center has been running a project for the storage and delivery of antidotes for acute poisoning patients of the Department of Health and Welfare, Korea. This study analyzed the results of this project over the past two years. Methods: The requests received by the National Emergency Medical Center and the data on the delivery process were analyzed. Results: This study analyzed a total of 121 patients with acute poisoning, who were requested to receive an antidote reserved at 20 key hospitals in 2015-2017, and whose age was $52.3{\pm}23.5\;years$; old; 54 were women. Intentional poisoning were 58.7%, and the home was the most common place of exposure (66.9%). The toxic substances were chemicals (32.2%), pesticides (27.3%), medicines (24.8%), and snake venom (4.1%). The patient's poison severity score was $2.4{\pm}0.7$ (median 3) indicating moderate-to-severe toxicity. Antidote administration was the cases treated in key hospitals 67.8% (82/121), in which transferred patients accounted for 57.3% (47/82). After receiving an antidote request from a hospital other than the key hospitals, the median was 75.5 minutes (range 10 to 242 minutes) until the antidote reached the patient, and an average of 81.5 minutes was required. The results of emergency care were intensive care unit (70.3%), general wards (13.2%), death (10.7%), and discharge from emergency department (5.0%). Conclusion: This study showed that the characteristics of acute poisoning patients treated with an antidote were different from previous reports of poisoned patients in the emergency department, and basic data on the time required for delivery from key hospitals was different.

Objective. Failure of first-line anti-tumor necrosis factor (TNF) agents in in rheumatoid arthritis patients leads to decisions among second-line biologic agents. To better inform these decisions, the therapeutic effectiveness of rituximab is compared with other second-line biologic agents in this observational study. Methods. Between November 2011 and December 2014, study subjects were observed for 12 month periods. Patients with an inadequate response to initial anti-TNF agent received either rituximab or alternative anti-TNF agents (adalimumab/etanercept/infliximab) based on the preference of patients and physicians. The efficacy end point of this study was the change in 28-joint count Disease Activity Score (DAS28) at six and 12 months from baseline. Safety data were also collected. Results. Ninety patients were enrolled in the study. DAS28 at six months did not change significantly whether the patients were treated with rituximab or alternative anti-TNF agents in intention-to-treat analysis (n=34, $-1.63{\pm}0.30$ vs. n=31, $-2.05{\pm}0.34$) and standard population set analysis (n=31, $-1.51{\pm}0.29$ vs. n=24, $-2.21{\pm}0.34$). Similarly, the change in DAS28 at 12 months did not reach statistical significance ($-1.82{\pm}0.35$ in the rituximab vs. $-2.34{\pm}0.44$ in the alternative anti-TNF agents, p=0.2390). Furthermore, the incidences of adverse events were similar between two groups (23.5% for rituximab group vs. 25.8% for alternative anti-TNF agents group, p=0.7851). Conclusion. Despite the limitations of our study, switching to rituximab or alternative anti-TNF agents after failure of the initial TNF antagonist showed no significant therapeutic difference in DAS28 reduction.

Cytotechnologists evaluate and analyze disorders of cells that constitute the human body, and are involved in the primary assessment of diverse diseases, including cancer. However, the employment conditions and workload of cytotechnologists are poorly understood. This study was undertaken to provide basic data for establishing the criteria for quality control certification factors based on the scope of effective task performance of cytotechnologists, and to provide results of their workload analysis according to the type of medical institution. The study was conducted by enrolling certified cytotechnologists working at various nationwide medical institutions. Our analysis revealed that 178 personnel (72.7%) were involved in primary screening of samples. On an average, the daily number of primary screening of samples performed per cytotechnologist (76 respondents) was determined to be 75.4 chapters (16.8 chapters/hours) at the university hospital level, 72.4 chapters (18.6 chapters/hours) at the general hospital level, and 231 chapters (32.6 chapters/hours) at professional trust institutions. Our results indicate the necessity to establish a consultant with the Korean Cell Pathology Association, to enable finding solutions to solve existing issues by establishing accurate standard guidelines for assessing cell screening.

Citizen participation and Living Lab are attracting interest as one of the major strategies for the success of smart cities. In a Living Lab, citizens, who are the end-users of technology, participate in the search for alternatives to define and solve problems and repeat experiments to verify alternatives in a circular process. The purpose of this research was to present an operating model of a citizen-participating online community platform to improve urban problems, implement and test it, and show its applicability. To this end, an operation model of a citizen-participating online community platform was proposed to improve urban problems. An online platform was designed and implemented to reflect the functions pursued by the operation model. Finally, a pilot test for the function was performed using the Oma Elementary School case located in Ilsan, Goyang-si, Gyeonggi-do. The operating model was designed with the city's pedestrian environment and children. As a result, the sharing and communicating process of urban issues among community members worked appropriately according to the designed intention. The Living Lab coordinator could visualize and view urban issues posted by users on a map based on location information. Visualizing the urban problem as a heat map confirmed that urban problems were concentrated in a specific area.

Spinal metastases can present with varying degrees of mechanical instability. The Spinal Instability Neoplastic Score (SINS) was developed as a tool to assess spinal neoplastic-related instability while helping to guide referrals among oncology specialists. Some previous papers suggested that the SINS was accurate and reliable, while others disagreed with this opinion. We performed a systematic review regarding the SINS to evaluate its accuracy and precision in predicting vertebral compression fractures (VCFs). The 21 included studies investigated a total of 2118 patients. Thirteen studies dealt with the accuracy of SINS to predict post-radiotherapy VCFs, and eight dealt with the precision. Among 13 studies, 11 agreed that the SINS categories showed statistically significant accuracy in predicting VCF. Among eight studies, body collapse was effective for predicting VCFs in six studies, and alignment and bone lesion in two studies. Location has no statistical significance in predicting VCFs in any of the eight studies. The precision of SINS categories was substantial to excellent in six of eight studies. Among the six components of the SINS, the majority of the included studies reported that location showed near perfect agreement; body collapse, alignment, and posterolateral involvement showed moderate agreement; and bone lesion showed fair agreement. Bone lesion showed significant accuracy in predicting VCFs in half of eight studies, but displayed fair reliability in five of seven studies. Although location was indicated as having near perfect reliability, the component showed no accuracy for predicting VCFs in any of the studies and deleting or modifying the item needs to be considered. The SINS system may be accurate and reliable in predicting the occurrence of post-radiotherapy VCFs for spinal metastasis. Some components seem to be substantially weak and need to be revised.
There will be many changes in job consciousness and job satisfaction due to changes in various job fields and social interests, and it is necessary to manage them efficiently for the organization to continue to grow. By analyzing factors influencing job satisfaction by occupation, the study intended to provide the necessary data for an efficient management plan. 400 Employees working at S tertiary hospital in Seoul from April 1st to April 15th, 2015 were targeted. An analysis of the validity and reliability of the influencing factors was conducted, and the allied health profession which showed the highest level of satisfaction in overall job satisfaction and influencing factors were identified. It was found that achievement, compensation and working environment in the medical doctor profession, achievement, compensation and job stability in the nursing profession, achievement and working environment in the allied health profession, achievement, interpersonal relationships, working environment, and job stability in the administrative profession, were the main influencing factors for job satisfaction. It can be seen that not only motivation factors but also hygiene factors affect job satisfaction. To increase the level of satisfaction, it is judged that systematic management of hygiene factors as well as motivation factors is necessary.

Background: In this study, we aimed to investigate the interaction effects of individual socioeconomic status and regional deprivation on the onset of diabetes complications and diabetes-related hospitalization among type 2 diabetes patients. Methods: Korean National Health Insurance Service National Sample Cohort data from 2002 to 2013 were used. A total of 50,954 patients newly diagnosed with type 2 diabetes from 2004 to 2012 and aged 30 years or above were included. We classified patients into six groups according to individual income level and neighborhood deprivation: 'high in advantaged,' 'high in disadvantaged,' 'middle in advantaged,' 'middle in disadvantaged,' 'low in advantaged,' and 'low in disadvantaged.' We calculated hazard ratios (HR) of onset of diabetes complication and diabetes-related hospitalization using the Cox proportional hazard model, with the reference group as diabetes patients with high income in advantaged regions. Results: In terms of the interaction effects of individual income level and regional socioeconomic level, even with the same low individual income level, the group with a high regional socioeconomic level (low in advantaged) showed low HRs for the onset of diabetes complication (HR, 1.04; 95% confidence interval [CI], 1.00-1.08) compared to the 'low in disadvantaged' group (HR, 1.10; 95% CI, 1.05-1.16). In addition, the 'high in advantaged' group showed slightly higher HRs for the onset of diabetes complication (HR, 1.06; 95% CI, 1.00-1.11) compared to the 'low in advantaged' and it appeared to be associated with slight mitigation of the risk of diabetes complication. For the low-income level, the patients in disadvantaged regions showed the highest HRs for diabetes-related hospitalization (HR, 1.29; 95% CI, 1.19-1.41) compared to the other groups. Conclusion: Although we need to perform further investigations to reveal the mechanisms that led to our results, interaction effects individual socioeconomic status and regional deprivation might be associated with on onset of diabetes complications and diabetes-related hospitalization among type 2 diabetes patients.

Background and Objectives The quality of life after thyroidectomy, such as voice change, is considered to be as important as control of the disease. In this study, we aimed to evaluate changes in both subjective and objective voice parameters after thyroidectomy resulting in normal morbidity of the vocal cords. Materials and Method In this prospective cohort study, 204 patients who underwent thyroidectomy with or without central neck dissection at a single referral center from Feb 2015 to Aug 2016 were enrolled. All patients underwent prospective voice evaluations including both subjective and objective assessments preoperatively and then at 2 weeks, 3, 6, and 12 months postoperatively. Temporal changes of the voice parameters were analyzed. Results Values of the subjective assessment tool worsened during the early postoperative follow-up period and did not recover to the preoperative values at 12 months postoperatively. The maximal phonation time gradually decreased, whereas most objective parameters, including maximal vocal pitch (MVP), reached preoperative values at 3-6 months postoperatively. The initial decrease in MVP was significantly greater in patients undergoing total thyroidectomy, and their MVP recovery time was faster than that of patients undergoing lobectomy (p=0.001). Patients whose external branch of the superior laryngeal nerve was confirmed intact by electroidentification showed no difference in recovery speed compared with patients without electroindentification (p=0.102), although the initial decrease in MVP was lower with electroidentification. Conclusion Subjective assessment in voice quality and maximal phonation time after thyroidectomy did not show recovery to preoperative values. Aggravation of MVP was associated with surgical extent and electroidentification.

Objectives: This study aims to analyze the medical record of eight cases of polycystic ovary syndrome (PCOS) in a local Korean medicine clinic, in order to provide evidence on Korean medicine treatment of PCOS and to suggest the direction of future studies. Methods: The medical records of eight cases diagnosed with PCOS based on 2003 Rotterdam Criteria and whose total testosterone level was 0.53 ng/ml and over were retrospectively analyzed. The primary outcome was total testosterone level, and the secondary outcomes included luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels, LH/FSH ratio, weight, last mentrual period (LMP), numerical rating scale (NRS) score of dysmenorrhea, and other associated symptoms pre- and post-treatment. Korean medicine treatment consists of the complex herbal prescription consisting of Yukmijihwang-tang, Baekho-tang, Daesiho-tang, and Gyejibokryeong-hwan, modified according to symptoms; acupuncture and electroacupuncture on 中脘 (CV12), 下脘 (CV10), 關元 (CV4), 石門 (CV5), 合谷 (LI4), 太衝 (LR3), 三陰交 (SP6), and 懸鍾 (GB39); and indirect moxibustion on 神闕 (CV8). Results: The average total testosterone level lowered statistically significantly after the treatment. The average FSH and LH levels lowered with insignificance, while the average LH/FSH ratio and weight lowered statistically significantly. During the treatment period of three to six months, every patient had the menstrual cycle shortened except for one case; and two cases with infertility problem succeeded in being pregnant. There was no adverse event. Conclusions: The Korean medicine treatment was found effective in treating PCOS, especially regarding hyperandrogenism, amenorrhea or oligomenorrhea, and infertility.
Background: In this study, we present recent trends in heart valve surgery in Korea through analyses of data from the Korea Heart Valve Surgery Registry (KHVSR). Methods: We enrolled 8,981 patients who were registered in the KHVSR from 2017 to 2020. Yearly trends in patients' baseline characteristics, surgical profiles, and early mortality rates were explored. The observed/expected mortality ratio (O/E ratio), calculated from the actual mortality in the KHVSR and the predicted mortality estimated using the EuroSCORE II, was also analyzed. Results: The proportion of aortic valve surgery significantly increased from 56.8% in 2017 to 60.3% in 2020. The proportion of all combined procedures and minimally invasive surgery significantly increased over the 4-year study period. The operative mortality rate was 2.9% in the entire cohort, while mitral valve repair showed the lowest mortality risk (0.9%). The mortality rates of isolated aortic valve replacement (AVR) significantly decreased from 2.1% in 2017 to 0.8% in 2020 (p=0.016). Overall, the O/E ratio was 0.784 (95% confidence interval [CI], 0.677-0.902) demonstrating significantly lower actual mortality risks than expected based on the EuroSCORE II. In particular, the O/E ratios were as low as 0.364 (95% CI, 0.208-0.591) for isolated AVR. Conclusion: The recent data from the KHVSR showed increasing trends for complex procedures and minimally invasive surgery in heart valve surgery in Korea, and demonstrated remarkably low risks of operative mortality.
