BACKGROUND: Alcohol has much effect on our lives as a taste food that people in almost all of the world generally have had. The effects of alcohol cause social problems as well as physical and psychological problems. Recently, interest about drinkirg increasingly rises as the rate of drinking accident increases in Korea. For this, our study examined the amount of alcohol consumption and early at-risk alcohol intake. METHODS: The prepared questionnaire was presented to subjects who were employees in Inchon . The anonymous, self-administered questionnaire was composed of questionnaire concerning alcohol consumption, early at-risk alcohol intake and doctor's role in drinking behaviour. RESULTS: Among 305 subjects, there were 189 (62%) men, 116 (38%) women whose mean age was 37. 9years. 87(28.5%)subjects were classified as high alcohol group and 218(71.5%) low alcohol group. High alcohol group was defined as early at-risk alcohol intake for men who were consuming 135g of alcohol per day, 630 per week and for women 90g per day, 270g per week. Low alcohol group was defined as early at-risk alcohol intake for men whose consumption was 90g per day, 450 per week and for women 45g per day, 270g per week . Mean alcohol consumption of drinker was 158.9g per week. 3 days per week people should not drink in order to avoid risk Although 54% of respondents thought doctors should ask about their drinkirg habits, only 16.4% of respondents reported ever being asked about alcohol intake on the subject. CONCLUSION: Early at-risk drinking subject in the study was much more than those suggested by NIH(National Institutes of Health). We conclude that primary care physicians should take more interest in screening, treating and preventing alcohol related problems and advise and educate patients to cut down or quit drinking.

Purpose: : This study aims to assess the extent of work value, psychological ownership, the nursing work environment, and retention intention, examine the correlation between these variables, and identify the factors that influence retention intention. The goal is to provide foundational data to enhance retention intention.Method : The study involved 159 nurses employed at a tertiary general hospital and a general hospital. Data were gathered through structured questionnaires and analyzed using an independent t-test, one-way ANOVA, Scheffé test, Pearson correlation coefficient, and multiple regression analysis with a simultaneous stepwise method, all conducted using the SPSS 26.0 software. Results: : The intention to remain in the profession was found to have a positive correlation with work value (r = .45, p ＜ .001), psychological ownership (r = .37, p ＜ .001), and the nursing work environment (r = .27, p = .001). Significant factors influencing the intention to stay included total clinical career (β = .17, p = .016), work value (β = .38, p ＜ .001), and psychological ownership (β = .19, p = .020). These variables accounted for 24.1% of the variance in the intention to remain in the profession (F = 17.71, p ＜ .001). Conclusion To enhance the intention of hospital staff to remain in their positions, it is crucial to identify and bolster positive psychological competencies, such as a sense of work value and psychological ownership.

Background: Although Korea ranks first in the suicide rate of elderly individuals, there is limited research on those who attempt suicide, with preventive measures largely based on population-based studies. We compared the demographic and clinical characteristics of elderly individuals who attempted suicide with those of younger adults who visited the emergency department after suicide attempts and identified the factors associated with lethality in the former group. Methods: Individuals who visited the emergency department after a suicide attempt from April 1, 2017, to January 31, 2020, were included. Participants were classified into two groups according to age (elderly, ≥65 years; adult, 18–64 years). Among the 779 adult patients, 123 were elderly. We conducted a chi-square test to compare the demographic and clinical features between these groups and a logistic regression analysis to identify the risk factors for lethality in the elderly group. Results: Most elderly participants were men, with no prior psychiatric history or suicide attempts, and had a higher prevalence of underlying medical conditions and attributed their attempts to physical illnesses. Being sober and planning suicide occurred more frequently in this group. In the elderly group, factors that increased the mortality rate were biological male sex (p<0.05), being accompanied by family members (p<0.05), and poisoning as a suicide method (p<0.01). Conclusion Suicide attempts in elderly individuals have different characteristics from those in younger adults and are associated with physical illness. Suicides in the former group are unpredictable, deliberate, and fatal. Therefore, tailored prevention and intervention strategies addressing the characteristics of those who are elderly and attempt suicide are required.

PURPOSE: Neonatal lupus is characterized by congenital complete heart block(CCHB), cutaneous rash, and laboratory abnormalities in infants born to mothers with systemic lupus erythematosus(SLE). This study aims to examine the incidence of CCHB and clinical outcome in neonates born to mothers with SLE. METHODS: The study group consisted of 49 neonates, born from 57 pregnancies of 55 women with SLE, diagnosed at Hanyang University Hospital for the period between January 1997 and January 2005. Clinical and laboratory data were retrospectively identified from medical record. RESULTS: There were 5(8.8 percent) spontaneous abortions and one(1.8 percent) still births among 57 pregnancies of 55 mothers. Of 49 live births, 15(26.3 percent) were premature and eight(12.3 percent) were small for their gestational age. There was one(1.8 percent) CCHB suspected during pregnancy on fetal echocardiograpy in a fetus of mother with systemic lupus erythematosus and the fetus was not born by artificial abortion because of mother. There was no CCHB among EKG findings of 49 newborns. Laboratory testing showed hematologic abnormalities among 25.6 percent(10/39) of the babies. 5.1 percent(2/39) and 7.7 percent(3/39) of them were diagnosed as neutropenia, and thrombocytopenia was seen respectively. Anti-SSA(Ro) and antiphospholipid antibodies were predictive factors for prematurity(P=0.003, P=0.049). Anticardiolipin antibodies were predictive factors for ventilatory care(P=0.018). CONCLUSION: The incidence of CCHB among neonates born to mothers with SLE, which was measured in this study, was lower than that in earlier studies. A high incidence of hematologic abnormalities was found in our study. It is suggested that careful examination should be made of skin for the diagnosis of neonatal lupus.

Purpose: Respiratory virus infection is a common cause of hospitalization in children. Rapid testing for respiratory viruses, such as the FilmArray method, can be clinically useful. However, insufficient evidence exists to support its use in standard clinical care. Methods: We retrospectively analyzed data from children under 18 years old who received the multiplex real-time polymerase chain reaction array (multiplex RT-PCR) method in 2017 and by FilmArray respiratory panel (FilmArray RP) in 2018. Results: Between January, 2017 and December, 2018, we reviewed data from 1,480 hospitalized children. The number of children with virus detection in respiratory viral PCR was 523 in the multiplex RT-PCR method and 419 in the FilmArray method. Seasonal virus outbreak patterns were similar to those of Korea Centers for Disease Control and Prevention in both groups. There was no difference between the 2 groups in the mean length of hospital stay. The time from admission to isolation by influenza infection was significantly shorter in the FilmArray group than in the multiplex RT-PCR group among patients who were not diagnosed with influenza infection by rapid antigen test at the time of admission. Conclusion The use of FilmArray method for respiratory viruses did not diminish length of hospital stay. However, the FilmArray method may quickly detect the prevalence of respiratory infection and aid in clinical treatment. In addition, it was related with a reduced time from admission to isolation by influenza infection in hospitalized children who were not identified with influenza infection by rapid antigen test at the time of admission.

Skin fibrotic disorders are understood to develop under the influence of various cytokines, such as transforming growth factor(TGF)-beta1, connective tissue growth factor(CTGF) and vascular endothelial growth factor (VEGF). To establish an appropriate animal model of skin fibrosis by exogenous application of growth factors, the author investigated the in vivo effects of growth factors by injecting recombinant TGF-beta1 protein and pCMV- Flag5-CTGF into the subcutaneous tissue of Sprague- Dawley rats. A single application of TGF-beta1 protein and CTGF DNA resulted in the formation of transient granulation tissue. Immunohistochemical finding showed increased expression of TGF-beta1 protein after injection of pCMV-Flag5-CTGF. In situ hybridization analysis revealed the expression of CTGF mRNA after injection of TGF-beta1 protein. VEGF expression was not affected by the TGF-beta1 and CTGF injection. These findings suggest TGF-beta1 and CTGF are deeply related with skin fibrosis and it appears that TGF-beta1 may cause the induction of CTGF expression. The animal model on skin fibrosis by exogenous application of TGF-beta1 protein and CTGF DNA developed in this study may be useful for future studies on fibrotic disorders.

Background and Objectives: Mesenchymal stem cells (MSCs) elicit therapeutic effects against liver fibrosis in animal models. Human liver stem cells (HLSCs) are cells isolated from human liver tissue that have mesenchymal morphology and express MSC markers. HLSCs also possess intrahepatic stem cell properties. We introduce a rat model of liver fibrosis and trans-portal transplantation of HLSC to demonstrate alleviation of liver fibrosis. Methods: and Results: Liver fibrosis was induced by intraperitoneal injection of Carbon tetrachloride (CCl 4 ). Sprague Dawley rats underwent simultaneous partial hepatectomy of the left hepatic lobe and HLSC transplantation via the portal vein. Gross appearance of the liver observed following CCl 4 injection showed cholestasis and surface nodularity. Sirius red staining revealed deposition of collagen fibers in the extracellular matrix (ECM). Following HLSC transplantation, human albumin secreting cells were detected by immunohistochemistry in liver specimens. Quantitative measurements of fibrosis area stained by Sirius red were compared between baseline and post-HLSC transplant (1×10 7 cells) following 10 weeks of CCl 4treatment liver specimens. Fibrosis area (p＜0.05), serum markers of liver inflammation and fibrosis (AST, ALT levels and APRI, p＜0.05) significantly decreased from baseline after HLSC transplantation. RNA expression in liver tissues revealed significant decrease in tissue inhibitor of matrix metalloproteinase 1 (TIMP1), TIMP2 expression and increase in hepatocyte growth factor expression following HLSC transplantation (p＜0.05). Conclusions HLSC transplantation effectively reduced the area of liver fibrosis with increased expression of factors promoting ECM degradation. These findings suggest the potential therapeutic role of HLSCs in various liver diseases presenting with liver fibrosis.
