PURPOSE: The purpose of the present study was to identify prevalence of excessive daytime sleepiness(EDS) and its associations with sleep habits, sleep problems, depression, subjective health status and obesity in community dwelling adults. METHOD: Data was collected from adults aged 20-59 years by random sampling. Subjects completed a questionnaire which was composed of the Epworth Sleepiness Scale, Center for Epidemiologic Studies Depression Scale, and questions that included items about sleep habits, sleep problems, subjective health status and sociodemographic characteristics. Height and weight were measured for calculation of body mass index. The statistical analyses was based on 3,302 adults (51.5% males and 48.5% females). Descriptive statistics, univariate logistic regression and multiple logistic regression were used. RESULT: The prevalence of EDS was 17.1%. Multiple logistic regression showed that the associated factors of EDS were depression, obesity, dissatisfaction with sleep time, irregular sleep, and habitual snoring. Depression was the most significant associated factor(adjusted odds ratio for severe depression=2.27, 95% Confidence Interval=1.73-2.96). CONCLUSION: EDS is a common symptom in adults. Our finding suggested that persons with a complaint of EDS should be completely assessed for depression and obesity as well as sleep problems.

Chronic obstructive pulmonary disease (COPD) is characterized by persistent airflow limitation that is usually progressive. It is a major cause of morbidity and mortality worldwide, leading to substantial and increasing economic and social burden. Palliative care for COPD patients aims to reduce symptoms and exacerbations and improve exercise tolerance and quality of life. It is difficult to make a prognosis for COPD patients due to the variable illness trajectory and advanced care of patients. However, severity of breathlessness, assessment of lung function impairment, and frequency of exacerbations can help to identify palliative care needs and determine effective methods to mitigate symptoms, which is discussed in this paper. In these patients, it is recommended to provide individualized palliative care along with curative/restorative care at the onset of COPD symptoms. Before launching a palliative care system in Korea, it is necessary to prepare pulmonary rehabilitation resources, patient-centered communication, timely palliative responsiveness, and a program for effective advanced care planning. A multidisciplinary approach involving collaboration with not only the respiratory and palliative care teams but also primary care offers a new model of care for these patients and should be considered with a priority.

Depression is a commonly encountered condition in the primary care that indicates low mood, loss of energy, sadness, loss of pleasure, sleep disorders or poor appetite, fatigue, and poor concentration. Of all the patients visiting the primary care, screening tests should be considered for the high-risk group and diagnosed using the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The purpose of treatment should be to assess and prevent the risk of suicides and administer medications, psychotherapy, and counseling to alleviate depression and restore daily life. Antidepressants are selected based on the comorbidities, side effects, and preferences of patients. These should be administered for a sufficient duration, followed by gradual reduction of the dosage and subsequent discontinuation of the drug. Counseling or psychotherapy may be considered for the treatment of depression. Primary care physicians should be skilled for screening, diagnosis, treatment, and counseling. Efficient treatment of depression in the primary care requires collaboration with the caregivers, psychiatrists, and nurse practitioners for assistance in its management.

Purpose: D-dimer levels are known to be associated with poor outcomes in patients with various cancers, but their significance at the end of life remains unclear. This study investigated D-dimer levels as a prognostic indicator for terminal cancer patients in the last hours of life. Methods: The retrospective study was conducted at a palliative care unit of a tertiary cancer center, using a database to analyze the records of patients treated from January 1, 2010 to December 31, 2018. In total, 67 terminal cancer patients with available data on Ddimer levels were included. Patients’ demographic data, clinical information, and laboratory values, including D-dimer levels, were collected. Survival was analyzed using the Kaplan– Meier method and the log-rank test. A Cox proportional-hazards model was used to identify prognostic factors of poor survival. Results: The most common site of cancer was the lung (32.8%) and the median survival time was 5 days. Most laboratory results, particularly D-dimer levels, deviated from the normal range. Patients with high D-dimer levels had a significantly shorter survival time than those with low D-dimer levels (4 days vs. 7 days; P=0.012). In the Cox regression analysis, only a high D-dimer level was identified as a predictor of a poor prognosis (hazard ratio, 1.83; 95% confidence interval, 1.09~3.07). Conclusion Our results suggest that at the very end of life, D-dimer levels may serve as a prognostic factor for survival in cancer patients.

Background: The factors associated with sleep disorder are controversial. This study aimed to evaluate the prevalence of sleep disorder and the factors associated with sleep disorder among Korean adult cancer survivors. Methods: In this cross-sectional study, we collected data on sleep problems as outcome variables, and sociodemographic and clinical information as predictor variables from cancer survivors at two university-affiliated hospitals. Sleep disorder was defined as “a difficulty in sleep initiation or sleep maintenance at least 3 times a week that started after a cancer diagnosis.” Multiple logistic regression analysis was performed with odds ratios (OR) and 95% confidence intervals (95% CI) to evaluate the factors associated with sleep disorder. Results: The participants were 1,893 Korean cancer survivors (mean age, 58.1 years; females 68.0%). The prevalence of sleep disorder among male and female cancer survivors were 16.5% and 20.3%, respectively. An increase of age by 1-year was associated with a 1.04 (95% CI, 1.01–1.07; P=0.011) times higher risk of sleep disorder in males, while an inverse association was found in females. In female survivors, high fear of cancer recurrence (FCR), high anxiety, menopause, and high EuroQol Visual Analog Scale were associated with 1.45 (95% CI, 1.06–1.98; P=0.020), 1.78 (95% CI, 1.25–2.55; P=0.002), 1.70 (95% CI, 1.08–2.67; P=0.022), and 0.59 (95% CI, 0.43–0.82; P=0.002) times higher risk of sleep disorder, respectively. In male survivors, living with a spouse/or partner was associated with 57% (95% CI, 0.20–0.95; P=0.036) lower risk of sleep disorder. Analyses of cancer sites showed that the factors associated with sleep disorder varied across cancer sites. Conclusion One-fifth of adult cancer survivors had sleep disorder. Age, menopausal status, FCR, anxiety, living with a spouse or partner, and quality of life were independently associated with sleep disorder in Korean cancer survivors.

Background: Alloantibodies against red blood cells (RBC) found in pregnant women can cause hemolytic disease in the fetus and newborn (HDFN). Therefore, checking and carefully observing the mother’s unexpected alloantibodies is essential during pregnancy. This study examined the frequency of unexpected antibodies according to the department. Methods: For patients who visited the authors’ hospital from December 31, 2020 to May 1, 2023 the results of RBC antibody screening and unexpected antibody identification tests were collected and classified according to the department. The antibody screening test was detected with Qwalys-3 DIAGAST, Loos Cedex, France) equipment using ABS HEMASCREEN (DIAGAST), and the antibody identification test was performed using the Resolve panel (Ortho-Clinical Diagnostics, San Diego, USA). The difference in frequency of each antibody according to the patient group was tested using Pearson’s chi-square test and Fisher’s exact test according to the relative frequency. Results: Among 46,193 patients who underwent unexpected antibody screening, 9,531 were obstetrics, and 18,313 were infertility centers. One hundred and seventy-seven patients underwent the unexpected antibody identification test: 57 obstetrics patients, 42 infertility center patients, and 78 positive patients who visited other departments.One hundred and ninety-three antibodies were identified, and there was no significant difference in the positive rate of unexpected antibodies by department. The antibody identified with the highest frequency was anti-M (18.1%) followed by anti-E (13.5%). Conclusion In the East Asian population, anti-M is frequently reported, causing clinical problems. Anti-M was also commonly observed in this study; so, the clinical features should be carefully observed if anti-M is identified.

PURPOSE: Seoul National University College of Medicine (SNUMC) introduced a multiple mini-interview (MMI) to assess the noncognitive ability of applicants in 2013. This study aims to examine whether students differ with regard to their personal career values and academic achievements by admission type. METHODS: We administered a survey about career values and self-perception of competencies. We then compared the survey results and academic achievements by admission type. Finally, the correlation coefficient between MMI score and academic achievement was calculated in the MMI group. The data were analyzed by t-test and correlation analysis. RESULTS: There was no statistically significant difference in career values between groups. For self-perception of competency, only the 'interact in heterogeneous groups' domain was higher for those who entered through the MMI. The MMI group had a higher and broader level of academic achievement. Within the MMI group, there was a significant correlation between grade point average and MMI station scores. CONCLUSION: The characteristics of students who entered through the MMI were more in accordance with the goals of SNUMC and the competency of future doctors. Considering the unique feature of premedical academic achievement, this result implies that such students have superior noncognitive abilities, such as self-development and internal motivation. How these differences change subsequently remains to be seen.

Lung cancer survivors need to undergo continuous care by primary care physicians after acute treatment. The health problems of lung cancer survivors are associated with their treatment: for example, severe pain, respiratory difficulty, poor quality of life, or pneumonitis. They also have various comorbidities, such as stroke, myocardial infarction, arrhythmia, chronic obstructive pulmonary disease, or psychological problems. Surveillance of lung cancer survivors is based on an annual chest CT with routine physical examination. Incidence of second primary cancer in lung cancer survivors is reported to increase in the remnant lung, head and neck, kidney, bladder, thyroid, stomach, and breast. Therefore, lung cancer survivors need to undergo regular health examination for early detection of cancer. Smoking status, weight change, drinking behavior, and vaccination, especially influenza and pneumococcal vaccination, should be assessed whenever the patient meets a clinician. The primary care physician would be expected to take on the role of managing the health problems of Korean lung cancer survivors comprehensively, including physical and psychosocial problems, from screening to survivorship care.

BACKGROUND: Being underweight has been related to health risks. However, little is known about the relationship between suicidal ideation and attempting to lose weight. This study was conducted to examine if there is an association between suicidal ideation and attempting to lose weight among underweight adults. METHODS: A cross-sectional study of 1,122 underweight adults (range, 19 to 69 years) was conducted based on the Korea National Health and Nutrition Examination Survey, 2007-2012. We examined suicidal ideation, doctor-diagnosed depression, depressive mood, stress, physical activity, health-related behavior, comorbidity, and socioeconomic status by weight loss attempts. Logistic regression analysis was performed to examine the association between suicidal ideation and weight loss attempts. The following covariates were controlled for: age, sex, physical activity, alcohol problem, marital status, education, income, occupation, self-perception of body image, chronic disease, and body mass index. RESULTS: There were 101 subjects in the weight loss attempt group and 1,021 in the non-attempt group. The attempt group had a higher risk of suicidal ideation (odds ratio [OR], 2.47; 95% confidence interval [CI], 1.35 to 4.53) and depressive symptoms (OR, 2.17; 95% CI, 1.19 to 3.98). After depressive symptoms were added to the covariates, the risk of suicidal ideation was also significant (OR 2.11, 95% CI: 1.03 to 4.35). The two groups did not significantly differ in doctor-diagnosed depression and stress. CONCLUSION: Weight loss attempts were associated with suicidal ideation in underweight Korean adults.

BACKGROUND: The aim of this study was to compare breast and cervical cancer screening rates between female cancer survivors and a population without cancer to identify factors related to cervical and breast cancer screening in cancer survivors. METHODS: We included 17,765 adults (738 cancer survivors and 17,027 individuals without cancer) in this study, all of whom who were 30 years of age or older and participated in the Fourth and Fifth Korean National Health and Nutritional Examination Surveys from 2007–2012. Multiple logistic regression analysis was performed to identify factors related to cervical and breast cancer screening uptake in female cancer survivors. RESULTS: The screening rate for breast cancer was 56.6%, which was higher than that in the non-cancer control group (P=0.001). The screening rate for cervical cancer was 51.4%, which was not different from that of the non-cancer control group. In terms of breast cancer screening, cancer survivors showed no significant difference in the rate of screening 5 years after their cancer diagnosis. However, cervical cancer survivors were less likely to have cervical cancer screening 10 years after their cancer diagnosis. There was no significant association between cancer screening and sociodemographic factors. CONCLUSION: Breast and cervical cancer screening rates in Korean female cancer survivors are low. Secondary primary cancer screening of female cancer survivors needs to be planned in a comprehensive manner, with the consideration of influences beyond sociodemographic factors.
