PURPOSE: The purpose of this study was to investigate the casual relationship between nurses' mentoring and turnover intention and to verify the goodness of fit between a hypothetical model and actual data in order to suggest an adequate model. METHODS: The survey was conducted with 434 nurses working in general hospitals in Seoul. Data were collected during February 2013, and analyzed with SPSS Windows 18.0 and AMOS 7.0. RESULTS: Mentoring was found to have a direct effect on decrease in role stress. Role stress had a direct effect on increase in burnout and mentoring, with role stress as a mediator, there was an indirect effect on burnout. Burnout had a direct effect on increase in turnover intention, and role stress, with burnout as a mediator, and mentoring, through role stress and burnout, an indirect effect was found on increase in turnover intention. CONCLUSION: The results of this study indicate that nursing managers should put effort into reducing role stress and burnout, while seeking to establish a more efficient mentoring system so that for nurses, there will be a lowering of turnover intention.

BACKGROUND: Microchimerism detected after solid organ transplatnation has been reported to be associated with improved graft survival with some controversies. However, the effect of pretransplantation microchimerism on the graft survival has not been studied to date. The aim of this study was to investigate the effect of pretransplantation fetomaternal microchimerism on the graft survival in renal transplantation. METHODS: A total of 27 cases of renal transplantation performed between mother and child pairs during the period from 1996 to 2004 at the Seoul National University Hospital were studied retrospectively. Presence of pretransplantation fetomaternal microchimerism was detected using DNA samples extracted from peripheral blood collected before the operation. Microchimerism for the HLA-DRB1 gene of non-inherited maternal antigen was detected using nested PCR-single strand conformation polymorphism (SSCP) method. The function and survival of allograft was compared between the groups with and without microchimerism. RESULTS: Microchimerism was detected in 10 (37%) of the 27 cases. In the group with microchimerism, serum creatinine levels at one and three years after transplantation tended to be lower in the patients with microchimerism than in those without microchimerism (one year, 1.1 vs 1.3 mg/dL, P=0.133; three years, 1.2 vs 1.5 mg/dL, P=0.083). The rejection free survival tended to be longer in the patients with microchimerism than in those without microchimerism (113.5 vs 72.5 months, P=0.146). CONCLUSIONS: This study was limited by small number of cases, and an extended study on a larger number of patients is needed to clarify the role of pretransplantation fetomaternal microchimerism on allograft survival.

Objective:
The development of individual subtypes based on biomarkers offers a cost-effective and timely avenue to comprehending individual differences pertaining to mental health, independent from individuals’ subjective insights. Incorporating 2-channel electroencephalography (EEG) and photoplethysmogram (PPG), we sought to establish a subtype classification system with clinical relevance.
Methods:
One hundred healthy participants and 99 patients with psychiatric disorders were recruited. Classification thresholds were determined using the EEG and PPG data from 2,278 individuals without mental disorders, serving to classify subtypes in our sample of 199 participants. Multivariate analysis of variance was applied to examine psychological distinctions among these subtypes. K-means clustering was employed to verify the classification system.
Results:
The distribution of subtypes differed between healthy participants and those with psychiatric disorders. Cognitive abilities were contingent upon brain subtypes, while mind subtypes exhibited significant differences in symptom severity, overall health, and cognitive stress. K-means clustering revealed that the results of our theory-based classification and data-driven classification are comparable. The synergistic assessment of both brain and mind subtypes was also explored.
Conclusion
Our subtype classification system offers a concise means to access individuals’ mental health. The utilization of EEG and PPG signals for subtype classification offers potential for the future of digital mental healthcare.

By comparing the data of prospectively and retrospectively enrolled cohorts, we evaluated whether the prospective cohort represented all patients in the retrospective cohort. The prospectively enrolled subjects were older and had lower CD4+ T cell counts, higher viral load. In addition, the initial antiretroviral treatment regimen of the prospective cohort consisted of less integrase strand transfer inhibitor-containing regimens. The 20-year survival rate was 51.8% in the prospective cohort and 84.6% in the retrospective cohort, respectively (P = 0.844). This study suggests the prospective cohort study may not represent all patients.

Background:
We investigated cardiovascular disease (CVD), risk factors for CVD, and applicability of the three known CVD risk equations in the Korean human immunodeficiency virus/ Acquired Immune Deficiency Syndrome (HIV/AIDS) cohort.
Materials and Methods:
The study parcitipants were HIV-infected patients in a Korean HIV/ AIDS cohort enrolled from 19 hospitals between 2006 and 2017. Data collected at entry to the cohort were analyzed. The 5-year CVD risk in each participant was calculated using three CVD risk equations: reduced CVD prediction model of HIV-specific data collection on adverse effects of anti-HIV drugs (R-DAD), Framingham general CVD risk score (FRS), and Korean Coronary Heart Disease Risk Score (KRS).
Results:
CVD events were observed in 11 of 586 HIV-infected patients during a 5-year (median) follow-up period. The incidence of CVD was 4.11 per 1,000 person-years. Older age (64 vs. 41 years, P = 0.005) and diabetes mellitus (45.5% vs. 6.4%, P <0.001) were more frequent in patients with CVD. Using R-DAD, FRS, and KRS, 1.9%, 2.4%, and 0.7% of patients, respectively, were considered to have a very high risk (≥10%) of 5-year CVD. The discriminatory capacities of the three prediction models were good, with c-statistic values of 0.829 (P <0.001) for R-DAD, 0.824 (P <0.001) for FRS, and 0.850 (P = 0.001) for KRS.
Conclusion
The FRS, R-DAD, and KRS performed well in the Korean HIV/AIDS cohort. A larger cohort and a longer period of follow-up may be necessary to demonstrate the risk factors and develop an independent CVD risk prediction model specific to Korean patients with HIV.

Herpes simplex virus type 2 (HSV2) meningitis primarily develops during or following a primary genital HSV2 infection that was acquired from sexual contact or through the birth canal during delivery from mother. We describe a 15 year old virgin without history of previous herpes simplex infection who developed 2 episodes of HSV2 meningitis. Although recurrent meningitis due to HSV is primarily seen in young or sexually active adults. HSV2 meningitis should be in the differential diagnosis of recurrent meningitis in adolescent patients.

BACKGROUND AND OBJECTIVES: The aim of this study was to determine the efficacy of induction chemotherapy with docetaxel and platinum in patients with hypopharyngeal carcinoma. SUBJECTS AND METHOD: The medical records of 66 patients who were diagnosed with hypopharyngeal carcinoma at our department from January 1996 to December 2008 were reviewed and retrospectively analyzed. The patients were divided into four groups according to treatment method: Group I was treated with radiation and induction chemotherapy consist of docetaxel and platinum (27); Group II was treated with surgery and induction chemotherapy consist of docetaxel and platinum (28), Group III was treated with radiation and induction chemotherapy consist of 5-FU and platinum (9) and Group IV was treated with surgery and induction chemotherapy consist of 5-FU and platinum (2). A total of 186 chemotherapy cycles were administered to patients and most of the patients received at least 2 cycles. RESULTS: The T-stage distribution at diagnosis was 7.5%, 42.4%, 28.8%, and 21.2% for T1, T2, T3, and T4, respectively. The N-stage distribution at diagnosis was 48.5%, 22.7%, 10.6%, 15.2%, and 9.1% for N0, N1, N2a, N2b, and N2c, respectively. The overall 3-year survival rate was 44.3%. The 3-year survival rate of each group was 42.6% in Group I, 54.8% in Group II, and 11.1% in Group III. There was no significant difference in survival between Groups I and III (p=0.074). There was no difference in sex, age, and N stage for 3-year survival rate. CONCLUSION: Although any valid conclusions could not be drawn because of the small number of patients examined here, induction chemotherapy consisting of docetaxel and platinum may improve the outcome of patients with hypopharyngeal carcinoma.

OBJECTIVES: To manage evidence-based diseases, it is important to identify the characteristics of patients in each country.METHODS: The Korea HIV/AIDS Cohort Study seeks to identify the epidemiological characteristics of 1,442 Korean individuals with human immunodeficiency virus (HIV) infection (12% of Korean individuals with HIV infection in 2017) who visited 21 university hospitals nationwide. The descriptive statistics were presented using the Korea HIV/AIDS cohort data (2006-2016).RESULTS: Men accounted for 93.3% of the total number of respondents, and approximately 55.8% of respondents reported having an acute infection symptom. According to the transmission route, infection caused by sexual contact accounted for 94.4%, of which 60.4% were caused by sexual contact with the same sex or both males and females. Participants repeatedly answered the survey to decrease depression and anxiety scores. Of the total participants, 89.1% received antiretroviral therapy (ART). In the initial ART, 95.3% of patients were treated based on the recommendation. The median CD4 T-cell count at the time of diagnosis was 229.5 and improved to 331 after the initial ART. Of the patients, 16.6% and 9.4% had tuberculosis and syphilis, respectively, and 26.7% had pneumocystis pneumonia. In the medical history, sexually transmitted infectious diseases showed the highest prevalence, followed by endocrine diseases. The main reasons for termination were loss to follow-up (29.9%) and withdrawal of consent (18.7%).CONCLUSIONS: Early diagnosis and ART should be performed at an appropriate time to prevent the development of new infection.

The number of persons infected by HIV/AIDS has consistently increased in Korea since the first case of HIV/AIDS infection in 1985 and reached 15,208 by 2016. About 1,100 new patients with HIV/ AIDS infections have emerged every year since 2013. In Korea, the Korea HIV/AIDS Cohort Study was established for the evidenced-based prevention, treatment, and effective management of patients infected with human immunodeficiency virus (HIV) in December 2006. This study monitored 1,438 patients, who accounted for about 10% of all patients with HIV/AIDS in Korea, for 10 years with the following aims: (1) to develop an administrative system for the establishment of a HIV/AIDS cohort-based study; (2) to standardize methodologies and the case report forms; and (3) to standardize multi-cohort data and develop a data cleaning method. This study aims to monitor at least 1,000 patients (excluding those for whom investigation had been completed) per year (estimated number of patients who can be monitored by January 2018: 939). By December 2016, the sex distribution was 93.3% for men, and 6.7% for women (gender ratio, 13.9:1.0), and 98.9% of all participants were Korean. More than 50.0% of the participants were confirmed as HIV positive after 2006. This study reports competitive, long-term research that aimed to develop policies for the prevention of chronic infectious diseases for patients with HIV. The data collected over the last decade will be used to develop indices for HIV treatment and health promotion.
