OBJECTIVE: To analyze the available data on the anti-anger effects of herbal medicines (HMs) as well as their underlying mechanisms in rat models. METHODS: From 6 electronic databases [PubMed, EMBASE, China National Knowledge Infrastructure (CNKI), Wanfang, Oriental Medicine Advanced Searching Integrated System (OASIS), and Research Information Sharing Service (RISS)], relevant animal experiments were searched by using "anger," "rats," and "animal" as search keywords. The last search was conducted on November 22, 2019, and all experiments involving rat models of anger and treatment using HMs published until the date of the search were considered. RESULTS: A total of 24 studies with 16 kinds of HMs were included. Most studies have used the "tail irritating method" and "social isolation and resident intruder" method to establish anger models. According to the included studies, the therapeutic mechanisms of HMs for anger regulation and important herbs by their frequency and/or preclinical evidence mainly incladed regulation of hemorheology (Bupleuri Radix, Paeoniae Radix Alba, and Glycyrrhizae Radix), regulation of sex hormones (Bupleuri Radix, Cyperi Rhizoma, and Paeoniae Radix Alba), regulation of neurotransmitters (Cyperi Rhizoma), regulation of anger-related genes (Bupleuri Radix, Glycyrrhizae Radix, and Paeoniae Radix Alba), and other effects. Overall, Liver (Gan) qi-smoothing herbs including Bupleuri Radix and Cyperi Rhizoma were the most frequently used. CONCLUSIONS This review found the frequent methods to establish an anger model, and major mechanisms of anti-anger effects of HMs. Interestingly, some Liver qi-smoothing herbs have been frequently used to investigate the anti-anger effects of HM. These findings provide insight into the role and relevance of HMs in the field of anger management.

Background: With increasing economic evaluation studies on the treatment of or screening tools for liver diseases that cause hepatocellular carcinoma (HCC), interest in the analysis of the medical utilization and costs of HCC treatment is increasing. Therefore, we aimed to estimate the medical utilization and costs of HCC patients, and calculate the cost of main procedures for HCC treatment, including liver transplant (LT), hepatic resection (HR), radiofrequency ablation (RFA), and transarterial chemoembolization (TACE). Methods: We analyzed claim data from January to December 2018 from the Health Insurance and Review and Assessment Service–National Patient Sample (HIRA-NPS-2018) dataset, including data of patients diagnosed with HCC (Korean Standard Classification of Diseases code C22.0) who had at least one inpatient claim for HCC. Results: A total of 715 HCC patients were identified. In 2018, the yearly average medical cost per HCC patient was ₩18,460K (thousand), of which ₩14,870K was attributed to HCC. Among the total medical costs of HCC patients, the inpatient cost accounted for the largest portion of both the total medical and HCC-related costs. The major procedures of HCC treatment occurred most frequently in the order of TACE, RFA, HR, and LT. The average medical cost per treatment episode was the highest for LT (₩87,280K), followed by HR (₩10,026K), TACE (₩4,047K), and RFA (₩2,927K). Conclusion By identifying the medical costs of HCC patients and the costs of the main procedures of HCC treatment, our results provide basic information that could be utilized for cost estimation in liver disease-related economic evaluation studies.

OBJECTIVE: This study evaluated whether emergency medical service (EMS) use was associated with early arrival and admission for definitive care among intracerebral hemorrhage (ICH) patients. METHODS: Patients with ICH were enrolled from 29 hospitals between November 2007 and December 2012, excluding those patients with subarachnoid hemorrhage, traumatic ICH, and missing information. The patients were divided into four groups based on visit type to the definitive hospital emergency department (ED): direct visit by EMS (EMS-direct), direct visit without EMS (non-EMS-direct), transferred from a primary hospital by EMS (EMS-transfer), and transferred from a primary hospital without EMS (non-EMS-transfer). The outcomes were the proportions of participants within early (<1 hr) definitive hospital ED arrival from symptom onset (pS2ED) and those within early (<4 hr) admission from symptom onset (pS2AD). Adjusted odds ratios were calculated to determine the association between EMS use and outcomes with and without inter-hospital transfer. RESULTS: A total of 6,564 patients were enrolled. The adjusted odds ratios (95% confidence intervals) for pS2ED were 22.95 (17.73–29.72), 1.11 (0.67–1.84), and 7.95 (6.04–10.46) and those for pS2AD were 5.56 (4.70–6.56), 0.96 (0.71–1.30), and 2.35 (1.94–2.84) for the EMS-direct, EMS-transfer, and non-EMS-direct groups compared with the non-EMS-transfer group, respectively. Through the interaction model, EMS use was significantly associated with early arrival and admission among direct visiting patients but not with transferred patients. CONCLUSION: EMS use was significantly associated with shorter time intervals from symptom onset to arrival and admission at a definitive care hospital. However, the effect disappeared when patients were transferred from a primary hospital.

The shock index (SI), modified shock index (MSI), and age multiplied by SI (Age SI) are used to assess the severity and predict the mortality of trauma patients, but their validity for geriatric patients is controversial. The purpose of this investigation was to assess predictive value of the SI, MSI, and Age SI for geriatric trauma patients. We used the Emergency Department-based Injury In-depth Surveillance (EDIIS), which has data from 20 EDs across Korea. Patients older than 65 years who had traumatic injuries from January 2008 to December 2013 were enrolled. We compared in-hospital and ED mortality of groups categorized as stable and unstable according to indexes. We also assessed their predictive power of each index by calculating the area under the each receiver operating characteristic (AUROC) curve. A total of 45,880 cases were included. The percentage of cases classified as unstable was greater among non-survivors than survivors for the SI (36.6% vs. 1.8%, P < 0.001), the MSI (38.6% vs. 2.2%, P < 0.001), and the Age SI (69.4% vs. 21.3%, P < 0.001). Non-survivors had higher median values than survivors on the SI (0.84 vs. 0.57, P < 0.001), MSI (0.79 vs. 1.14, P < 0.001), and Age SI (64.0 vs. 41.5, P < 0.001). The predictive power of the Age SI for in-hospital mortality was higher than SI (AUROC: 0.740 vs. 0.674, P < 0.001) or MSI (0.682, P < 0.001) in geriatric trauma patients.

INTRODUCTIONEffective mentoring helps interns in the early stages of their medical career to reach personal and professional goals. This study investigated the mentoring experience of Korean interns during medical internship and evaluated mentoring effects to facilitate the development of future mentoring programmes.

METHODSParticipants were interns being trained at Chonnam National University Hospital, South Korea, in 2011. Interns were asked to complete a questionnaire about their mentoring experiences and job satisfaction.

RESULTSA total of 61 medical interns participated in the study, giving a response rate of 70.1%. Among these interns, 26 (42.6%) had mentoring experiences, with an average of 2.3 ± 1.9 mentors per mentee. Mentees usually discussed career planning and concerns regarding their personal and social lives with their mentors. Perceived quality of the mentor was significantly more important for male mentees than for female mentees. Female interns without a mentor made significantly less effort to seek a mentor than their male counterparts. Having and not having a mentor resulted in significant differences in the interns' job satisfaction.

CONCLUSIONFewer than half of the medical interns had mentoring experiences. Results suggest that the mentoring relationship may be less satisfying and more challenging for female interns. Effective mentoring may not only help interns plan their medical career, but also increase job satisfaction. Mentoring programmes during medical internship should be expanded and supported, as it is the initial step in a medical career.

This study aimed to describe the characteristics of out-of-hospital cardiac arrest (OHCA) according to specific activity types at the time of event and to determine the association between activities and outcomes according to activity type at the time of event occurrence of OHCA. A nationwide OHCA cohort database, compiled from January 2008 to December 2010 and consisting of hospital chart reviews and ambulance run sheet data, was used. Activity group was categorized as one of the following types: paid work activity (PWA), sports/leisure/education (SLE), routine life (RL), moving activity (MA), medical care (MC), other specific activity (OSA), and unknown activity. The main outcome was survival to discharge. Multivariate logistic analysis for outcomes was used adjusted for potential risk factors (reference = RL group). Of the 72,256 OHCAs, 44,537 cases were finally analyzed. The activities were RL (63.7%), PWA (3.1%), SLE (2.7%), MA (2.0%), MC (4.3%), OSA (2.2%), and unknown (21.9%). Survival to discharge rate for total patients was 3.5%. For survival to discharge, the adjusted odds ratios (95% confidence intervals) were 1.42 (1.06-1.90) in the SLE group and 1.62 (1.22-2.15) in PWA group compared with RL group. In conclusion, the SLE and PWA groups show higher survival to discharge rates than the routine life activity group.

PURPOSE: This study was designed to determine the epidemiological and clinical characteristics of patients suspected or confirmed with to be infected by the pandemic 2009 H1N1 virus in one emergency medical center. METHODS: This was a prospective observational study. It was conducted between September 1 and November 30, 2009 in one tertiary academic emergency department. We recorded clinical and epidemiologic features of patients infected by the pandemic 2009 H1N1 virus. A follow-up telephone survey was done to determine the final outcome of infection. This survey was conducted by ED personnel 1 week after the initial visit. Multivariate logistic regression analysis was done for the association between disposition or H1N1 influenza diagnosis and potential predictors. RESULTS: During the study period, a total 5,317 patients visited the influenza clinical center of our emergency department. Among them, 1,472 patients (27.7%) were confirmed as influenza A by RT-PCR methods. Among RT-PCR positive patients, 90 (1.7%) were admitted to the ward and 7 to the intensive care unit. Five patients needed mechanical ventilation and one patient was diagnosed as ARDS; the ARDS patient fully recovered. There was no mortality caused by H1N1. The median age of confirmed patients was 9 years (range, 1 month~81 years); 825 patients (56.1%) were male. Incident rates for common symptoms were: fever (92.8%), cough (84.1%), and rhinorrhea (44.0%) by. A total of 40.3% (593/1472) patients were of pre-school age (range, 1 month~7 years, median 4 years). In young patients, clinical characteristics were similar to those of adults. Male, young age, contact history, lack of seasonal influenza vaccination, chronic renal failure, malignancy, and pregnancy were significantly associated with a confirmed diagnosis of H1N1. Hypertension, chronic renal failure, malignancy, neurologic disease, dyspnea, seizure, vomiting, and chest pain were also associated with risk of admission to the hospital. CONCLUSION: Surveillance of H1N1 virus cases shows that the majority of those infected have a mild illness. The 2009 H1N1 virus is common among individuals of pre-school age. Few H1N1-related severe illnesses occur in young individuals.

BACKGROUND AND OBJECTIVES: Arrhythmia is known to be a major cause of death in acute myocardial infarction (AMI). Reperfusion arrhythmias (RA) may also occur during angioplasty or thrombolysis. As yet, the clinical significances of RA and angiographic characteristics of the patients who develop RA during primary angioplasty and stenting are not clearly defined. METHODS: The study group consisted of 60 patients treated with primary angioplasty or stenting for AMI (angioplasty 13, stenting 47 patients). The patients were classified into 2 groups according to RA [RA (-) N=36/RA(+) N=24]: demographic and angiographic characteristics including time to reperfusion and incidence of pre-infarct angina were analyzed. RESULTS: The RA occurred in 40% of patients undergoing primary angioplasty or stenting (24/60 patients). The minor arrhythmias were more common after reperfusion (transient bradycardia 14, accelerated idioventricular rhythm 11, premature ventricular contraction 4 cases): major arrhythmias were uncommon (ventricular tachycardia/fibrillation 5, asystole 1 case). In the two groups, baseline clinical characteristics were similar except for pain to reperfusion time [RA (-): RA (+)=490.8+/-291.7: 252.9+/-109.2 minutes, P=0.001]. There was a trend toward a greater incidence of RA in the right coronary infarct-related artery [RA (-): RA (+)=16.7: 41.7%, P=NS]. The RA occurred in totally occluded artery (TIMI 0) with a giant thrombus and first ballooning in 19/24 patients (79.2%). The RA disappeared with conservative managements including pacemaker insertion and cardiopulmonary resuscitation and there were no differences in major adverse cardiac events in the two groups during follow-up. CONCLUSIONS: These findings suggest that the RA are frequent events during primary angioplasty but unrelated to clinical and angiographic characteristics except for reperfusion time and do not influence short-term prognosis in AMI.
