BACKGROUND: Aging can serve as an underlying mechanism of chronic obstructive pulmonary disease (COPD). Also, smoking, which is the most common cause of COPD, is responsible for the systemic manifestations of the disease, independently from the lung function alterations. The purpose of this study was to analyze the effect of aging on the occurrence of cigarette smoking induced COPD. METHODS: For this analysis, we evaluated smoking status by a lifestyle intervention program and measured the occurrence of COPD by the Korea National Health and Nutrition Examination Survey (KNHANES) from 2005 to 2015. RESULTS: Aging and smoking were significantly effected on the lung function of COPD patients. Especially, the smoking duration is exaggerated in the presence of old age for older COPD patients. CONCLUSION The result showed that COPD patients exhibit aging and smoking duration related severity. The prevalence of COPD kept increasing internationally. Knowing the risk factor of COPD quantitatively and finding out the interaction among risk factors could be valuable predictors for preventing COPD.

PURPOSE: This study was designed to develop quality outcome indicators for nursing homes and community-based home care that would contribute to an appropriate evaluation and improvement of quality of long term care in Korea. METHODS: The preliminary quality indicators of long term care were developed from a literature review and clinical expert panel. A content validity testing was done using a panel of experts who were selected from academic and clinical field of long-term care. The final quality indicators were confirmed after application in four nursing homes and four home care agencies to test clinical validity. RESULTS: The preliminary quality indicators consisted of 3 domains and 19 indicators. The final quality indicators were composed of 4 domains and 17 indicators. CONCLUSION: This study demonstrated the feasibility of outcome quality indicators in long term care. These quality indicators can be effectively used to evaluate the quality of nursing home and home care and to improve the quality of care in the Korean long-term care system.

PURPOSE: Understanding changes in pathogen and pneumonia prevalence among pediatric pneumonia patients is important for the prevention of infectious diseases. METHODS: We retrospectively analyzed data of children younger than 18 years diagnosed with pneumonia at 117 Emergency Departments in Korea between 2007 and 2014. RESULTS: Over the study period, 329,380 pediatric cases of pneumonia were identified. The most frequent age group was 1–3 years old (48.6%) and the next was less than 12 months of age (17.4%). Based on International Classification of Diseases, 10th revision diagnostic codes, confirmed cases of viral pneumonia comprised 8.4% of all cases, pneumonia due to Mycoplasma pneumoniae comprised 3.8% and confirmed cases of bacterial pneumonia 1.3%. The prevalence of confirmed bacterial pneumonia decreased from 3.07% in 2007 and 4.01% in 2008 to 0.65% in 2014. The yearly rate of pneumococcal pneumonia also decreased from 0.47% in 2007 to 0.08% in 2014. A periodic prevalence of M. pneumoniae pneumonia (MP) was identified. CONCLUSION: The increased number of patients with pneumonia, bacterial pneumonia, pleural effusion, and empyema in 2011 and 2013–2014 resulted from an MP epidemic. We provide evidence that the frequency of confirmed cases of bacterial pneumonia and pneumococcal pneumonia has declined from 2007 to 2014, which can simultaneously reflect the effectiveness of the pneumococcal conjugate vaccine.

Purpose: With the rapid expansion of the field of interventional neuroradiology (INR) and the diverse background of aspiring neuro-interventionists, there is an ever increasing need to establish consensus criteria for training and accreditation in INR. Materials and Methods: We performed a survey to explore the current state of criteria for training and accreditation in INR. The questionnaire consisting of 11 questions was emailed to the members of World Federation of Interventional and Therapeutic Neuroradiology (WFITN) worldwide. It was focused on the training charter, training program, qualifying examination, and education after training program as perceived by practitioners in each country. Results: A total of 52 WFITN members in 19 countries responded to the questionnaire. There was a huge variation internationally and nationally due to the unique situation and challenges in each country and institution. Criteria for training and accreditation in INR were well established in some countries of Europe, North America, and Asia but not specified in other countries. Conclusion It is critical to establish consensus criteria for training and accreditation in INR in order to ensure safe practice and continued expansion and development of INR as a specialty.

BACKGROUND: Reducing the gaps in health inequality at a regional level and improving health equity have been emphasized in Korea, it is essential to accurately measure the burden of disease by region. This study aimed to estimate years of life lost (YLLs) in 17 Si and Do of Korea from 1997 to 2015 and determine the trends of regional differences in health status and disease structure. METHODS: YLL was calculated by subtracting the age at death from the life expectancy. Data on the region, gender, and age-stratified cause-specific death were obtained from the Korean Statistical Information Service of Statistics Korea. RESULTS: Age-standardized YLLs per 100,000 population decreased by year in all regions from 1997 to 2015 by 27.4% (27.5% for men; 27.2% for women). Despite the decline in YLLs, the regions with the highest and lowest YLLs did not change between 1997 and 2015. The diseases showing regional differences were caused by injury, often classified as avoidable mortality. We also confirmed that YLLs were higher in the regions with a higher deprivation index. CONCLUSION The present study identified that YLLs differed by regions in Korea with specific causes. The findings of this study can be used by decision-makers to prioritize the reduction of regional gaps in premature deaths.

Delayed ischemic stroke associated with intractable vasospasm after clipping of unruptured intracranial aneurysms (UIAs) has been rarely reported. We report a patient with delayed ischemic stroke associated with intractable vasospasm following UIA clipping. A middle-aged female underwent surgery for unruptured middle cerebral artery bifurcation aneurysms. The patient tolerated the neurosurgical procedure well. Seven days postoperatively, the headache was unbearable; a postcraniotomy headache persisted and abruptly presented with global aphasia and right-sided hemiplegia after a nap. Emergency digital subtraction angiography showed severe luminal narrowing with segmental vasoconstriction, consistent with severe vasospasm. The patient’s neurological deficit improved after chemical angioplasty. Neurosurgeons should pay close attention to this treatable/preventive entity after neurological deterioration following UIA clipping, even in patients without subarachnoid hemorrhage.

Purpose: We applied a low-dose fluoroscopic protocol in routine diagnostic cerebral angiography and evaluated the feasibility of the protocol. Materials and Methods: We retrospectively reviewed a total of 60 patients who underwent diagnostic cerebral angiography for various neurovascular diseases from September to November 2019. Routine protocols were used for patients in the first phase and low-dose protocols in the second phase. We compared radiation dose, fluoroscopy time, and complications between groups. Results: Age, diseases, and operators were not significantly different between the two groups. The mean fluoroscopy dose significantly decreased by 52% in the low-dose group (3.09 vs. 6.38 Gy·cm2 ); however, the total dose was not significantly different between the two groups (34.07 vs. 33.70 Gy·cm2 ). The total fluoroscopic time was slightly longer in the low-dose group, but the difference was not statistically significant (12.2. vs. 12.5 minutes). In all patients, angiography was successfully performed without complications. Conclusion The low-dose fluoroscopy protocol is feasible to apply for diagnostic cerebral angiography in that this protocol could significantly reduce the fluoroscopic dose.
