PURPOSE: The purpose of this study was to identify the level of distress and quality of life (QoL) in esophageal cancer patients, and to identify the factors influencing QoL METHODS: A sample of 103 patients who have esophageal cancer were included in a descriptive study. The instruments used were the Distress Thermometer and Problem List, and the Functional Assessment of Cancer Therapy-General (FACT-G) version 4. RESULTS: The mean distress score of the subjects was 4.06±2.04 out of 10. The total mean score of quality of life was 66.39±12.86 out of 108, the highest category was physical well-being with a mean item score of 21.78±5.51, the lowest was emotional well-being with a mean item score of 14.69±3.68. The levels of distress and QoL were negatively correlated (r=−.61, p<.001). Stepwise regression analysis revealed that the QoL of the patients was explained by type of treatment and distress. These variables explained 35% of the variance in QoL. CONCLUSION: The QoL of patients with esophageal cancer was relatively low, and the type of treatment and distress was the most important factor affecting quality of life. Thus, to improve the QoL of patients with esophageal cancer, it is important to assess their distress and to provide appropriate interventions.

Human mitochondrial DNA (mtDNA) is generally used to identify highly degraded forensic samples, particularly when the extracted DNA is not sufficient for nuclear DNA analysis. However, direct sequencing, the most widely used mtDNA analysis method, is laborious and time-consuming, and precludes the simultaneous analysis of many samples. Here, we describe a rapid and simple screening method for mtDNA analysis in Koreans using single base extension (SBE) methods. Sixteen highly polymorphic mtDNA SNPs from the control region were selected, and a multiplex SBE system was constructed to analyze them. Because the developed system consists of two duplex PCRs, which produce small amplicons with fewer than 270 bp, it works well with highly degraded samples such as old skeletal remains. Using this multiplex SBE system, 145 different haplotypes were expected to be observed from 593 unrelated Koreans. Seventy-three haplotypes were expected to be observed only once, and the most frequent haplotype was expected to occur 80 times. Since the mean number of pairwise differences was estimated to be 4.55, the developed system could be useful to exclude samples that do not match evidence and reference samples. Therefore, the multiplex SBE system used in this study will be a useful tool to analyze many samples simultaneously and to efficiently screen out non-matching mtDNA sequences in forensic casework.

Purpose: The diagnostic usefulness of fetal echocardiography in congenital heart disease is well known. One of the indications for fetal echocardiography is presence of extracardiac anomalies and such coexistent congenital heart disease may have important implications for obstetric and neonatal management. MATERIALS AND METHODS: 496 women with singleton pegnancies with amgenital anomalies that underwent penatal care and follow-up in Severance Hospital for 5 years from 1991 to 1995 were evaluated for the incidence of congenital heart disease. RESULTS: The incidence of congenital heart disease in fetuses with the associated extracardiac anomalies were as follows; central nervous system 6.9%(11/160), gastro-intestinal system 10.7%(8/75), genito-urinary sysem 4.7%(4/85), others 5.6%(4/72). Thirty-one of eighty-ane fetuses with congenital heart disease were found to have the associated extracardidac anomalies and ten of them chenoscenal abnormalities. CONCLUSION: We recommend that fetuses with congenital extracardiac anomalies sbould be checked for the presence of congenital heart disease and chmmosomal abnormalities, if needed.

OBJECTIVES: Angiotensin-converting enzyme (ACE) gene polymorphism has been reported to be associated with depression and therapeutic outcome in depression. The purpose of this study was to determine whether ACE gene polymorphism is associated with seasonal variation in mood and behavior in a young Korean college student sample. METHODS: 297 young Korean medical students were recruited in this study. All subjects were free of major medical and psychiatric problems. They were genotyped for the ACE gene polymorphism and evaluated the seasonal variation in mood and behavior by the Seasonality Pattern Assessment Questionnaire (SPAQ). RESULTS: Global Seasonality Score (GSS) of SPAQ between three genotypes were not different. However, comparison of the group that showed seasonality of mood and behavior during winter with the group that did not showed seasonality indicated significant difference in genotype distribution (chi-square=6.79, p=0.034). The D allele non-carrier (II genotype) frequency was significantly higher in winter seasonality group than non-seasonality group (chi-square=6.59, p=0.010; odds ratio [OR]=2.27, 95% confidence interval [CI] 1.20-4.28). CONCLUSION: These results suggest that the ACE gene polymorphism is related to winter-type seasonality in a Korean population.

PURPOSE: The purpose of this study was to confirm the influence of hematoonchology unit nurses' positive psychological capital and death awareness on their terminal care performance. METHODS: This descriptive study data were collected from self-reported questionnaire filled by 127 oncology nurses at a tertiary hospital in Seoul, Korea. The variables were positive psychological capital, death awareness, and terminal care performance. Data were analyzed using SPSS version 22.0 software. RESULTS: The participants scored 3.93±0.83 on positive psychological capital, 3.68±0.99 on death awareness and 2.86±0.65 on terminal care performance. The three variables were positively correlated. The factors affecting the nurses' terminal care performance were hope and resilience in the subcategory of positive psychological capital and experience of death of family members, relatives or friends within the past year; The explanatory power was 32.1%. CONCLUSION: It is necessary to develop educational programs to foster hope, resilience, etc. in hematooncology unit nurses to improve their quality of terminal care performance.

Purpose: This study aimed to examine the predictive factors of COVID-19 vaccination behavior by evaluating the moderating effect of perceived behavioral control on the theory of planned behavior. Methods: Data were collected from August 6 to August 31, 2022 from 235 college students (aged 20~29 years) across 12 universities using a structured web-based survey. Statistical analyses were conducted using the SPSS and AMOS software. Results: Attitudes toward COVID-19 vaccination, subjective norms, and intention to be vaccinated significantly influenced COVID-19 vaccination behavior. Attitudes and subjective norms indirectly affected COVID-19 vaccination behavior through intention to vaccinate, whereas intention to vaccinate had a direct effect. The moderating effect of perceived behavioral control on the relationship between subjective norms and intention to vaccinate was significant. Conclusion Interventions that foster a positive attitude toward COVID-19 vaccination and bolster subjective norms and perceived behavioral control can boost the intention to be vaccinated and facilitate the uptake of COVID-19 vaccination.

The Sertoli-Leydig cell tumor is a rare sex cord stromal tumor of the ovary, accounting for less than 0.5% of all primary ovarian neoplasm. This tumor is the most common type of all virilizing ovarian tumors. However, only one-third of patients develop virilization. Recently, we experienced a case of intermediately differentiated Sertoli-Leydig cell tumor with amenorrhea and so we present it with brief review of literature.

BACKGROUND: Lower back pain (LBP) is the most common musculoskeletal disease in adults over the age of 50. LBP is associated with physical activity and mental health such as depression or suicidal thoughts. We aimed to analyze the association between LBP and mental health and that between physical activity and depressive mood in LBP patients among Korean adults over the age of 50.METHODS: We included 2,681 adults in the analysis, who participated in the 2013 Korean National Health and Nutrition Examination Survey, and used a t-test, logistic regression analysis, and chi-squared test via complex sampling. We analyzed the association between LBP and mental health, various kinds of physical activity, and depressive mood after adjusting for confounding factors.RESULTS: Poor mental health (perception of stress, diagnosis of depression, depressive mood, suicidal thoughts, and suicide attempts) were significantly associated with LBP. The LBP group was 2.077 times more likely to be diagnosed with depression and was 4.666 times more likely to have suicidal thoughts than the control group. Exercise, such as walking, was associated with a reduced risk of depressive mood in subjects with LBP.CONCLUSION: LBP patients were at high risk of being diagnosed with depression, experiencing suicidal thoughts and depressive mood, and attempting suicide. In LBP patients, walking was associated with a reduced depressive mood.

BACKGROUND: Causal hypotheses suggest that alcohol-related disorders may also cause psychiatric disorders and problems, or vice versa. The association between alcohol consumption and mental health is important from both research and therapeutic viewpoints. Therefore, we aimed to analyze the association between alcohol consumption and mental health (perceived stress, depressive mood, suicidal ideation, quality of life) in Korean adults over 19 years old.METHODS: We finally included 5,399 adults who had participated in the Korean National Health and Nutrition Examination Survey in 2015, and analyzed the association between alcohol consumption and mental health, using logistic regression.RESULTS: Perceived stress was associated with alcohol consumption in problem drinkers (odds ratio [OR]=1.35, 95% confidence interval [CI]=1.13–1.61). Depressive mood was associated with alcohol consumption in moderate and problem drinkers (OR=0.90, 95% CI=0.71–1.11 and OR=1.35, 95% CI=1.06–1.70, respectively). Suicidal ideation was not associated with alcohol consumption in moderate and problem drinkers (P=0.063 and P=0.068, respectively). Quality of life was associated with alcohol consumption in moderate and problem drinkers (OR=0.48, 95% CI=0.41–0.57 and OR=0.77, 95% CI=0.66–0.92, respectively).CONCLUSION: We found that moderate drinkers have a lower risk of depressive mood and a higher quality of life as compared to low drinkers. However, problem drinkers have a higher quality of life but a higher risk of perceived stress and depressive mood as compared to low drinkers.
