To assess the association between oral health and general health, this study examined the relationship between chewing difficulty and twelve chronic health conditions such as hypertension, hyperlipidemia, diabetes, cerebro- and cardiovascular disease, musculoskeletal disease, respiratory disease, eye/nose/throat disease, stomach/intestinal ulcer, renal dysfunction, thyroid disease, depression, and cancer in Korea. The study population was 3,066 elders aged 65 years old and more from the fourth Korean National Health and Nutrition Examination Survey. Chewing difficulty was measured on a 5-point Likert scale. Chronic conditions were assessed by self-reported questionnaire. Confounders were age, gender, education, income, smoking, drinking, and obesity. Chi-square test, general linear model, and multiple logistic regression model were done with complex sampling design. Musculoskeletal disease (adjusted odds ratio=1.33), respiratory disease (adjusted odds ratio=1.52), and cancer (adjusted odds ratio=1.58) were independently associated with chewing difficulty. Multiple chronic conditions with more than 4 chronic disease showed significant association with chewing difficulty (adjusted odds ratio=1.37).

Background: Aging societies face social problems of increased medical expenses for older adults due to increased geriatric diseases. This study aims to analyze the relationship between the state change of multiple chronic conditions (MCC) and out-of-pocket medical expenses in the elderly aged 60 or older. Methods: The 2014-2018 Korean Longitudinal Study of Aging data were used for 2,202 elderly people. Four status change groups were established according to the change in the number of chronic diseases. The association between the change of MCC and the out-of-pocket medical cost was analyzed using the generalized estimating equation model analysis. Results: The average out-of-pocket total medical costs were 1,384,900 won for participants with MCC and 542,700 won for those without MCC, which was a statistically significant difference (p<0.0001). Compared to the reference group (simple chronic disease, SCD→SCD), the change in multiple chronic conditions significantly increased the total out-of-pocket medical expenses in MCC→MCC and SCD→MCC groups (MCC→MCC: 𝛽=0.8260, p<0.0001; SCD→MCC: 𝛽=0.6607, p<0.0001). Conclusion: In this study, it was confirmed that the prevalence of MCC increased with age, and the out-of-pocket medical cost increased in the case of MCC. Continuity of treatment can be achieved for patients with MCC, and the system and management of treatment for MCC are required to receive appropriate treatment.

Purpose: Workers with chronic health problems find it difficult to maintain their work because of socioeconomic difficulties. The purpose of this study was to evaluate the relationships between physical, ergonomic, and mental health hazards in the workplace and chronic health problems of Korean workers. Methods: A total of 28,807 wage workers participated in the study and were selected using the Fifth Korean Working Conditions Survey (2017). Multiple logistic regression analysis was used to determine the associations between physical, ergonomic, and mental health hazards and chronic health problems. Results: Of the participants, 1,220 (4.23%) had chronic health problems. Even after adjusting the general characteristics, vibration, noise, high temperature, low temperature, dust, chemical and cigarette smoke, fatigue and painful posture, dragging or pushing or moving of heavy objects, repetitive hand or arm movements, working with a computer or smartphone, use of internet or e-mail, and anxiety situations increased the risk of chronic health problems. Conclusion: The study reaffirms that exposure of physical, ergonomic, and mental health hazards in the workplace significantly increases the risk of chronic health problems.

Korean Red Ginseng (KRG) plays a key role in heme oxygenase (HO)-1 induction under physical and moderate oxidative stress conditions. The transient and mild induction of HO-1 is beneficial for cell protection, mitochondrial function, regeneration, and intercellular communication. However, chronic HO-1 overexpression is detrimental in severely injured regions. Thus, in a chronic pathological state, diminishing HO-1-mediated ferroptosis is beneficial for a therapeutic approach. The molecular mechanisms by which KRG protects various cell types in the central nervous system have not yet been established, especially in terms of HO-1-mediated mitochondrial functions. Therefore, in this review, we discuss the multiple roles of KRG in the regulation of astrocytic HO-1 under pathophysiological conditions. More specifically, we discuss the role of the KRG-mediated astrocytic HO-1 pathway in regulating mitochondrial functions in acute and chronic neurodegenerative diseases as well as physiological conditions.

CD4 and CD8 T cells are key players in the immune response against both pathogenic infections and cancer. CD4 T cells provide help to CD8 T cells via multiple mechanisms, including licensing dendritic cells (DCs), co-stimulation, and cytokine production. During acute infection and vaccination, CD4 T cell help is important for the development of CD8 T cell memory. However, during chronic viral infection and cancer, CD4 helper T cells are critical for the sustained effector CD8 T cell response, through a variety of mechanisms. In this review, we focus on T cell responses in conditions of chronic Ag stimulation, such as chronic viral infection and cancer. In particular, we address the significant role of CD4 T cell help in promoting effector CD8 T cell responses, emerging techniques that can be utilized to further our understanding of how these interactions may take place in the context of tertiary lymphoid structures, and how this key information can be harnessed for therapeutic utility against cancer.

Few studies have been conducted on the detailed routes of medical care utilization under the National Health Insurance. This study was undertaken to identify the utilization patte군 of health care facilities among industrial workers and their dependents. One of the largest health insurance association was purposively chosen for this objective. The association had 345, 757 members as of 31 December, 1990. The study sample of 297, 948 subjects have been drawn from the membership pool on the basis of their continuous membership status during 1 January through 31 December 1990. This study has tried to identify differential utilization patterns between acute and chronic conditions, and among standard income classes. All the diagnoses were recoded in a manner to achieve the objective of this study. As for acute diseases, most age group had used one medical facility as much as by 60% except the age group of 1-4, This young age group had used over three different health facilities as much as by 10.9-15.8%. The finding suggests that some policy measures by sought for remedying the excessive/inappropriate use of services. In addition, mid-income classes(between 17 and 48) were more likely to use multiple sources of care than lower income classes(between 1 and 16) and upper income classes(above 49). This study has revealed that chronic cases are more likely to pursue multiple sources of care, however those with chronic conditions tend to use single health facility more than those with acute conditions(67.9% versus 52.4%). As many as 12.2% have visited more than three health facilities in chronic conditions, but 5.9% for acute conditions. The most likely source of care was primary clinics for both acute and chronic conditions. Compared with the role of general hospital, small-size hospitals found to play a minimal role in the care and referral of patients. This indicates the need of strengthening the function of small-size hospitals. While a minor cross utilization of western medicine and pharmacy was noted, no significant boundary crossing was identified between western medicine and oriental medicine, or between pharmacy and oriental medicine. It is too early to confirm that whether there is substitutability or cross utilization among these alternative sources of care. A further study is needed to identify these relationship.

Objectives : This study investigated the effects of social support and chronic medical conditions on depressive symptoms in elderly people living alone in a rural community. Methods : Sociodemographic information on 173 subjects aged 65 years or older who lived alone in a rural community and were recipients of National Basic Livelihood Security was collected and analyzed. All participants completed the Korean Form of the Geriatric Depression Scale and the Lubben Social Network Scale. Additionally, the current prevalence of chronic medical conditions that interfere with the activities of daily living was examined. Multiple logistic regression analysis was conducted to analyze the associations of social support and chronic medical conditions with depressive symptoms. Results : Social support(odds ratio: OR, 0.96; 95% confidence interval: 95% CI, 0.92-0.99) and chronic medical conditions(OR, 1.59; 95% CI, 1.23-2.05) were significantly associated with depressive symptoms in all subjects. When analyzed by gender, social support served as a protective factor against depressive symptoms in elderly men only(OR, 0.91; 95% CI, 0.83-0.99), and chronic medical conditions increased the risk of depressive symptoms in elderly women only(OR, 1.74; 95% CI, 1.26-2.40). Furthermore, osteoarthritis and lumbar pain were risk factors for depressive symptoms in all subjects(OR, 2.24; 95% CI, 1.10-4.56 and OR, 2.10; 95% CI, 1.08-4.12) and in elderly women(OR, 4.07; 95% CI, 1.68-9.84 and OR, 3.34; 95% CI, 1.47-7.57), respectively. Conclusion : This study indicates that improving the social support and managing the chronic medical conditions of elderly people living alone are important for the prevention of depression in this population. Additionally, the present results suggest that it is necessary to establish different depression-prevention strategies for elderly men and women living alone.

The study was to examine the relationships among health promoting lifestyle, level of anxiety, and perceived health status and to reveal those variables. affecting health promoting lifestyle in Korean immigrants in the United States. The subjects were 425 adults chosen from Korean religious and social organizations located in New York from April 25th through July 5th. 1996. Data analyses were conducted by using Pearson correlation coefficients, t-test, ANOVA, and stepwise multiple regression. The results were as follows : Health promoting lifestyle was significantly different according to age, religion. occupation, and the length of residence in the US. Those insured and those with no chronic conditions revealed a significantly higher score in health promoting lifestyle. Significant differences in the level of anxiety were found according to education, marital status, occupation, family income, and the length of residence. Those with no chronic conditions experienced a significantly lower level of anxiety. In the subscales of the health promoting lifestyle profile, self-actualization and interpersonal relationship revealed higher scores, whereas the scores of stress management, health responsibility, and exercise were lower. Those subjects whose perceived health status was very good, showed the lowest level of anxiety and the highest score on the health promoting lifestyle profile. Negative correlations were observed between the health promoting lifestyle profile and the level of anxiety, and between the perceived health status and the level of anxiety. Health promoting lifestyle was significantly predicted by the level of anxiety(22.0%), age(2.0%), health insurance(1.1%), respectively.
