As the elderly population increases, they are increasingly affected by oral health problems. Therefore, efforts are being made to improve the oral health of older people, alleviate mental discomfort, and reduce unmet dental needs. This study was conducted to confirm the relationship between the National Health Insurance Elderly Denture Coverage and the unmet dental need for the edentulous elderly, as part of the protection policy. We analyzed the 2011 and 2013 Community Health Survey data of the edentulous elderly, aged 75 years or older, before 2012. In order to more precisely confirm the effects of the denture donation policy on unmet dental care, basic life recipients who were subject to the free elderly prosthetic project were excluded from the analysis. The final analysis included 20,400 subjects. According to our investigation of the factors that affect the unmet dental needs of the elderly, the National Health Insurance Elderly Denture Coverage did not affect unmet dental needs. The statistically significant variables that affected the unmet dental needs of the elderly were education and income levels, which are representative socioeconomic status variables. The lower the level of education, the unhealthier the dental care experience, and income levels showed a similar tendency. The elderly who have a low socioeconomic status are more likely to experience unmet dental needs because they lack the knowledge and socioeconomic ability to pay for dental care. Therefore, the policy for health protection of the entire elderly population should be continuously expanded. In addition, the socioeconomically vulnerable groups may have health problems due to the restriction of medical use, which may lead to quality of life deterioration.

OBJECTIVES: To investigate compliance of hypertension patients using modified Theory of Reasoned Action(TRA). METHODS: The data were collected for 7-12 April 1997, by interviewing 190 hypertension patients in Hwachon, Kangwon-do. The analytical techniques employed include contingency table analysis and logit analysis. RESULTS: 15.1% of patients were unaware of the fact that he/she has hypertension and 11.2% did not know that he/she should take drug. 26.8% of patients took drug continuously, 20.1% had drug intermittently, and 53.1% had never have treatment. In the contingency table analysis, several variables were found to be significantly related to patient compliance. They included variables for attitude towards the consequences of taking drugs, normative beliefs, systolic BP at the enrollment, knowledge of how to take hypertensive drugs, variables for general health behavior and experience with having health worker's home visit. The logit analysis was performed by two steps. First step uses experience with drug treatment of hypertension as the dependent variable, and second step uses continuity of treatment. Included in the predictors that are significantly related to the former analysis are subjected norms produced by combining normative beliefs and motivation to comply, knowledge of how to take hypertensive drugs, and opinion about natural recovery of diseases. The only significant determinant of continuous treatment was knowledge of how to take hypertensive drugs. CONCLUSIONS: The results of analysis suggest the usefulness of TRA as a framework for the study of compliance of hypertensive patients. The findings have some practical implication as well. One is that efforts for enhancing compliance should be directed not only patients but also to other persons influencing patient's attitude and behavior. It also suggest that correct understanding of hypertension treatment is essential to perform the appropriate patient role.

Background: and Purpose: Choline alfoscerate (CA) is an acetylcholine precursor known for its beneficial effect on cognition in patient with Alzheimer’s disease dementia (ADD).However, there is little evidence of its effects in patients with mild cognitive impairment (MCI). We assessed the influence of CA on the progression from MCI to all-cause dementia or ADD in three observational Korean databases using a Common Data Model (CDM). Methods: Patients who were diagnosed with MCI and were aged over 60 years were included.After propensity score matching, 3,062 matched pairs patients using CA use and those not using CA were included. The Cox regression model was used to analyze the hazard ratio (HR) of CA use for conversion from MCI to all-cause dementia or ADD. Subgroup analyses were performed based on sex, acetylcholine esterase inhibitor (AchEI) use, and donepezil use. Results: A meta-analysis across three hospitals revealed that CA use was not associated with the progression from MCI to all-cause dementia (hazard ratio [HR], 0.93; 95% confidence interval [CI], 0.59–1.26) or ADD (HR, 1.05; 95% CI, 0.51–1.59). Subgroup analyses revealed that CA use was not related to progression to all-cause dementia or ADD when stratified by sex, AchEI use, and donepezil use. Conclusions In this multicenter cohort study based on the Observational Medical Outcomes Partnership CDM real-world data, no association was noted between CA use and disease progression from MCI to all-cause dementia or ADD.

Background: and Purpose Previous research on patients with acute ischemic stroke (AIS) has shown a 0.5% incidence of major gastrointestinal bleeding (GIB) requiring blood transfusion during hospitalization. The existing literature has insufficiently explored the long-term incidence in this population despite the decremental impact of GIB on stroke outcomes. Methods: We analyzed the data from a cohort of patients with AIS admitted to 14 hospitals as part of a nationwide multicenter prospective stroke registry between 2011 and 2013. These patients were followed up for up to 6 years. The occurrence of major GIB events, defined as GIB necessitating at least two units of blood transfusion, was tracked using the National Health Insurance Service claims data. Results: Among 10,818 patients with AIS (male, 59%; mean age, 68±13 years), 947 (8.8%) experienced 1,224 episodes of major GIB over a median follow-up duration of 3.1 years. Remarkably, 20% of 947 patients experienced multiple episodes of major GIB. The incidence peaked in the first month after AIS, reaching 19.2 per 100 person-years, and gradually decreased to approximately one-sixth of this rate by the 2nd year with subsequent stabilization. Multivariable analysis identified the following predictors of major GIB: anemia, estimated glomerular filtration rate <60 mL/min/1.73 m2 , and a 3-month modified Rankin Scale score of ≥4. Conclusion Patients with AIS are susceptible to major GIB, particularly in the first month after the onset of AIS, with the risk decreasing thereafter. Implementing preventive strategies may be important, especially for patients with anemia and impaired renal function at stroke onset and those with a disabling stroke.
