Purpose: The purpose of this study was to identify the fall risk factors and to evaluate the effectiveness of the Morse Fall Scale(MFS) as an assessment tool among hospitalized inpatients. Methods: The medical records of a total of 294 patients who admitted to hospital from January 1 to December 31, 2010 were reviewed. One hundred forth seven patients who had experienced fall were matched with 147 patients who have never experienced fall. The fall information was obtained from electronic medical records and fall reports. Results: There were significant differences in visual disturbances, pain, emotional disturbances, sleep disorder, urination problems and elimination disorder at admission between fallers and non-fallers. Patients who had higher MFS scores at admission were more likely to fall as compared to the patients with lower MFS scores. When falls did occur, these occurred within five days following admission, in the patient room, among patients with alert mental status, and among patients who were ambulant with some assistance. Conclusion: The findings of this study support the need of using risk assessment tool for predicting risk for falls. This finding can be used as a useful resource to develop nursing intervention strategies for fall prevention at the hospital.

Purpose: The objectives of this study were to determine the prevalence, incidence, duration and risk factors for delirium following liver transplantation while the patients were in the acute stage and admitted to the intensive care unit. Method: A retrospective chart review of 106 patients who had liver transplantation was conducted. A delirium risk factor checklist was used, to collect preoperative and postoperative data. Descriptive analysis, t-test, x2-test, and logistic regression analyses were used for data analysis. Results: The post-transplantation incidence of delirium was 29.3% (n=31). Multivariate analysis revealed that risk factors were preoperative conditions in the patients including spontaneous bacterial peritonitis, hepatorenal syndrome, and postoperative laboratory test results, such as hyperbilirubinemia. Conclusion: Therefore, a daily delirium risk factor assessment should be conducted before liver transplantation as a way to identify risk of delirium after the liver transplantation and to effectively manage delirium when it occurs.

The goal of this study was to examine which factors influence consumers' demands to reveal the identity of GMO(Genetically Modified Organism) food, risk perception, and decision-making to purchase it. Consumers perceived its risk, and demanded labeling to identify it. Not many consumers wanted to buy GMO food. The results also revealed as follows. First, the level of demand to label for identifying GMO food were high among female consumers, consumers with negative attitude, and consumers severly perceived its risk. The level of perceived risk was high among consumers who were old and had high income, exercised their own healthy programs, showed negative attitude toward GMO food, and demanded strongly for labelling. Second, old consumers, consumers with high income, consumers concerning more about health, consumers with negative attitude and strong demand to label for identifying GMO food were more likely to perceive risk highly for GMO food. Third, consumers' attitudes and the level of perceived risks for GMO food significantly influenced the decision-making to purchase GMO food. However, other variables turned out not to affect consumers' decision-making to purchase it.

Purpose: Early sexual intercourse is associated with poor health outcomes in adolescents. It is known that sexual intercourse coincides with other health risk behaviors such as smoking, drinking, and using drugs. The purpose of this study is to identify the relationships between sexual intercourse and health risk behaviors among Korean and US adolescents using nationally representative data. Methods: Data were collected from the 2011 Korea Youth Risk Behavior Web-based Survey (29,676 students) and 2011 Youth Risk Behavior Surveillance System (10,135 high school students). Logistic regression analysis was performed. Results: In Korea, students who had sexual intercourse accounted for 7.0% in total. Among these, 9.7% were male and 4.2% were female students. In the US, a total of 51.3% students had sexual intercourse, and the proportion of the US male (49.3%) and female (53.4%) students who had sexual intercourse was similar. Korean and US students who experienced sexual intercourse were more likely to smoke, drink alcohol, and use drugs. Conclusion: Since the results of this study show the relationships between sexual intercourse and health risk behaviors, it is necessary to develop comprehensive sex education programs with effective strategies to reduce health risk behaviors in adolescents.

Objectives: To identify simultaneous behavioral changes in alcohol consumption, smoking, and weight using a fixed-effect model and to characterize their associations with disease status. Methods: This study included 7 000 529 individuals who participated in the national biennial health-screening program every 2 years from 2009 to 2016 and were aged 40 or more. We reconstructed the data into an individual-level panel dataset with 4 waves. We used a fixed-effect model for smoking, heavy alcohol drinking, and overweight. The independent variables were sex, age, lifestyle factors, insurance contribution, employment status, and disease status. Results: Becoming a high-risk drinker and losing weight were associated with initiation or resumption of smoking. Initiation or resumption of smoking and weight gain were associated with non-high-risk drinkers becoming high-risk drinkers. Smoking cessation and becoming a high-risk drinker were associated with normal-weight participants becoming overweight. Participants with newly acquired diabetes mellitus, ischemic heart disease, stroke, and cancer tended to stop smoking, discontinue high-risk drinking, and return to a normal weight. Conclusions: These results obtained using a large-scale population-based database documented interactions among lifestyle factors over time.

Liver cancer is the fourth leading cause of death worldwide. Well-known risk factors include hepatitis B virus and hepatitis C virus, along with exposure to aflatoxins, excessive alcohol consumption, obesity, and type 2 diabetes. Genomic variants play a crucial role in mediating the associations between these risk factors and liver cancer. However, the specific variants involved in this process remain under-explored. This study utilized a bioinformatics approach to identify genetic variants associated with liver cancer from various continents. Single-nucleotide polymorphisms associated with liver cancer were retrieved from the genome-wide association studies catalog. Prioritization was then performed using functional annotation with HaploReg v4.1 and the Ensembl database. The prevalence and allele frequencies of each variant were evaluated using Pearson correlation coefficients. Two variants, rs2294915 and rs2896019, encoded by the PNPLA3 gene, were found to be highly expressed in the liver tissue, as well as in the skin, cell-cultured fibroblasts, and adipose-subcutaneous tissue, all of which contribute to the risk of liver cancer. We further found that these two SNPs (rs2294915 and rs2896019) were positively correlated with the prevalence rate. Positive associations with the prevalence rate were more frequent in East Asian and African populations. We highlight the utility of this population-specific PNPLA3 genetic variant for genetic association studies and for the early prognosis and treatment of liver cancer. This study highlights the potential of integrating genomic databases with bioinformatic analysis to identify genetic variations involved in the pathogenesis of liver cancer. The genetic variants investigated in this study are likely to predispose to liver cancer and could affect its progression and aggressiveness. We recommend future research prioritizing the validation of these variations in clinical settings.

Objective: The purpose of this study is to identify the incidence risk of cardiovascular disease (CVD) in the workplace, and to suggest the prediction models for level of CVD incidence risk. Background: CVD can be caused by various factors related to personal habits such as diet and exercise, or genetics. However it can also be caused and aggravated by work, making the elimination of such risk factors at work crucial disease (KOSHA, 2013). Method: The distribution of CVD risk assessment levels of 162 workers was compared with the acquired medical examination data to discuss the necessity of assigning additional risk factors. Two alternative risk assessment models were given to enhance the accuracy of the evaluation; adjusting risk scores given in the KOSHA GUIDE H-1-2013 (alternative 1) and building a matrix of KOSHA GUIDE H-1-2013 and risk assessment results based on work condition levels (alternative 2). To verify the suggested models, medical examination results of 12 workers approved of convalescence were referred to. Results: The second alternative showed more relevance between the results and workers approved of convalescence in predicting the risk group when applied to actual heath examination data from the approved workers. The power of description of the new method for determining the risk of CVD incidence, 83.3%, is higher than that of KOSHA GUIDE H-1-2013, 25%. Conclusion: Results of this study imply that more approved workers had been from unmanaged normal groups than managed risk groups, raising the importance of CVD management. Application: The new prediction model considering working time and shift work developed in this study is expected to be a fundamental data for risk analysis and management of CVD in the workplace.
