This study is to understand the status of influenza vaccination in patients with chronic obstructive pulmonary disease and to analyze factors affecting vaccination behavior. The aim of this study was to investigate the factors influencing influenza vaccination among Chronic Obstructive Pulmonary Disease (COPD) patients over 40 years, sociodemographic characteristics and health behaviors. Data of 2,370 adults of over 40 years who answered to the survey on National Health and Nutrition and influenza vaccination from 2014 to 2018 was used and analyzed. Overall influenza vaccination rate was 59.2%. Logistic regression analysis revealed that factors influencing on influenza vaccination were over 65 age, a low income, Never/past smoker, experience of health screening. It is needed to seek a strategy to develop a vaccination program in consideration of factors associated with influenza vaccination among COPD patient over 40 years.

This study presents a systematic literature review aimed at integrating and analyzing the research findings regarding the components of various self-care intervention programs conducted for individuals with chronic obstructive pulmonary disease (COPD) both domestically and internationally. The paper selection criteria were established based on materials from PubMed, CINAHL, EMBASE, /MEDLINE, RISS, DBpia, KISS, and KMbase databases, covering the period from January 1, 2000, to September 30, 2022. The inclusion criteria included controlled pre-post experimental study designs. A total of 23 studies were included in this systematic review. The intervention-related factors examined included the sample size, type of intervention mediator, intervention frequency, and duration. Additionally, factors associated with intervention effects, such as measurement tools and variables, were analyzed. The findings of the analysis support the notion that self-care intervention programs for COPD can contribute to the prevention of symptom exacerbation and hospital readmissions among patients. Consequently, the development of a tailored self-care intervention program specifically designed for COPD patients in South Korea is warranted, considering aspects such as patient accessibility, convenience, and motivation for long-term sustainability.

D-dimer is a fibrin degradation product (FDP), a small protein fragment present in the blood after a blood clot is degraded by fibrinolysis. D-dimer concentration is widely used for determining thrombosis and thromboembolism. Because one major cause of thromboembolism is congestive heart failure in human, we investigated the degree and risk of thromboembolism in dogs with different stage of congestive heart failure caused by chronic mitral valvular insufficiency (CMVI). The plasma level of d-dimer was evaluated in 20 healthy dogs and 30 dogs with different stage of congestive heart failure caused by CMVI. The d-dimer concentrations were measured by a commercialized assay kit. The plasma levels of d-dimer were not significantly different between healthy and CMVI dogs. Furthermore, there was no association of d-dimer concentrations to left atrium to aorta (LA/Ao) ratio, left ventricular dimension at diastole to aorta (LVIDd/Ao) ratio and severity of heart failure in our study population. Our study results implied that the degree of thromboembolism in canine heart failure might be minimal or the plasma d-dimer test might not be reliable for detecting thromboembolism in dogs.

본 논문에서는 호흡 연동 장치와 EBT로부터 획득한 폐실질 영상에 대하여 동적 윤곽선 모델 방법과 영역 성장법을 이용하여 폐실질 영역을 검출하였다. 그런 다음 , 검출된 폐실질 영역내에서의 각종 정량적 요소들을 도출하여 농도 분포 곡선에대한 분석을 하였다. 동적 윤곽선 모델방법에서 페실질 영역의 낮은 휘도 준위와 폐의 윤곽선 벡터 방향을 고려한 에너지 함수를 제안하였다. 그리고 폐실질 영역 성장법에서는 폐실질 영역내의 분포한 공기 성분에 대한 화소를 확장시켜 효과적으로 폐실질 영역을 검출하였다. 추출된 폐실질 영역내의 빈도 분포 곡선을 분석하여 정상군과 비교한 결과 만성 폐쇄성 폐질환자에서는 정상인에 비하여 평균 농도,최대 빈도 농도, 최대 상승 기울기 농도가 낮았으며, 농도 분포곡선은 더 낮은 쪽으로 이동하였음을 알 수 있었다. 또한, 특발성 폐섬유증 환자에서는 평균 농도, 최대 빈도 농도, 최대 상승 기울기 농도가 모두 증가되었고 농도 분포 곡선은 더 높은쪽으로 이동하였다. 폐실질 영역을 추출하여 히스토그램 분포에 대한 정량적 분석을 함으로써 정상인으로부터 만성 폐쇄성 질환자의 폐섬유증 환자를 구분할 수 있었다.
