  • The purpose of this study was to develop a basic framework and criteria for evaluation of quality care provided to patients with the attributes of disease in the home care nursing field, and to provide measurement tools for home health care in the future. The study design was a developmental study for evaluation of hospital-based HCN(home care nursing) in Korea. The study process was as follows: a home care nursing study team of College of Nursing. Yonsei University reviewed the nursing records of 47 patients who were enrolled at Yonsei University Medical Center Home Care Center in March, 1995. Twenty-five patients were insured at that time, were selected from 47 patients receiving home care service for study feasibility with six disease groups; Caesarean Section (C/S), simple nephrectomy, Liver cirrhosis(LC), chronic obstructive pulmonary disease(COPD), Lung cancer or cerebrovascular accident(CVA). In this study, the following items were selected : First step : Preliminary study 1. Criteria and items were selected on the basis of related literature on each disease area. 2. Items were identified by home care nurses. 3. A physician in charge reviewed the criteria and content of selected items. 4. Items were revised through preliminary study offered to both HCN patients and discharged patients from the home care center. Second step : Pretest 1. To verify the content of the items, a pretest was conducted with 18 patients of which there were three patients in each of the six selected disease groups. Third step : Test of reliability and validity of tools 1. Using the collected data from 25 patients with either cis, Simple nephrectomy, LC, COPD, Lung cancer, or CVA. the final items were revised through a panel discussion among experts in medical care who were researchers, doctors, or nurses. 2. Reliability and validity of the completed tool were verified with both inpatients and HCN patients in each of field for researches. The study results are as follows: 1. Standard for discharge with HCN referral The referral standard for home care, which included criteria for discharge with HCN referral and criteria leaving the hospital were established. These were developed through content analysis from the results of an open-ended questionnaire to related doctors concerning characteristic for discharge with HCN referral for each of the disease groups. The final criteria was decided by discussion among the researchers. 2. Instrument for measurement of health statusPatient health status was measured pre and post home care by direct observation and interview with an open-ended questionnaire which consisted of 61 items based on Gorden's nursing diagnosis classification. These included seven items on health knowledge and health management, eight items on nutrition and metabolism, three items on elimination, five items on activity and exercise, seven items on perception and cognition, three items on sleep and rest, three items on self-perception, three items on role and interpersonal relations, five items on sexuality and reproduction, five items on coping and stress, four items on value and religion, three items on family. and three items on facilities and environment. 3. Instrument for measurement of self-care The instrument for self-care measurement was classified with scales according to the attributes of the disease. Each scale measured understanding level and practice level by a Yes or No scale. Understanding level was measured by interview but practice level was measured by both observation and interview. Items for self-care measurement included 14 for patients with a CVA, five for women who had a cis, ten for patients with lung cancer, 12 for patients with COPD, five for patients with a simple nephrectomy, and 11 for patients with LC. 4. Record for follow-up management This included (1) OPD visit sheet, (2) ER visit form, (3) complications problem form, (4) readmission sheet. and (5) visit note for others medical centers which included visit date, reason for visit, patient name, caregivers, sex, age, time and cost required for visit, and traffic expenses, that is, there were open-end items that investigated OPD visits, emergency room visits, the problem and solution of complications, readmissions and visits to other medical institution to measure health problems and expenditures during the follow up period. 5. Instrument to measure patients satisfaction The satisfaction measurement instrument by Reisseer(1975) was referred to for the development of a tool to measure patient home care satisfaction. The instrument was an open-ended questionnaire which consisted of 11 domains; treatment, nursing care, information, time consumption, accessibility, rapidity, treatment skill, service relevance, attitude, satisfaction factors, dissatisfaction factors, overall satisfaction about nursing care, and others. In conclusion, Five evaluation instruments were developed for home care nursing. These were (1)standard for discharge with HCN referral. (2)instrument for measurement of health status, (3)instrument for measurement of self-care. (4)record for follow-up management, and (5)instrument to measure patient satisfaction. Also, the five instruments can be used to evaluate the effectiveness of the service to assure quality. Further research is needed to increase the reliability and validity of instrument through a community-based HCN evaluation.

  • Background: The causes of exertional desaturation in patients with COPD can be multifactorial. We aimed to investigate factors predict exertional desaturation in patients with moderate to severe COPD. Methods: We tested 51 consecutive patients with stable COPD (FEV1/FVC, $40{\pm}13%$ predicted). Patients performed a six minute walk test (6MWT). Pulse oxymetric saturation (SpO2) and pulse rate were recorded. Results: Oxygen desaturation was found in 15 subjects after 6MWT, while 36 subjects were not desaturated. Lung diffusing capacity was significantly lower in desaturation (DS) group ($62{\pm}18%$ predicted) compared with not desaturated (ND) group ($84{\pm}20$, p<0.01). However there was no statistical difference of FEV1/FVC ratio or residual volume between two groups. The pulse rate change was significantly higher in the desaturated compared with the not desaturated group. Six minute walking distance, subjective dyspnea scale, airflow obstruction, and residual volume did not predict exertional oxygen desaturation. Independent factors assessed by multiple logistic regression revealed that a pulse rate increment (odd ratio [OR], 1.19; 95% confidence interval [CI], 1.01~1.40; p=0.02), a decrease in baseline PaO2 (OR, 1.105; 95% CI, 1.003~1.218; p=0.04) and a decrease in lung diffusing capacity (OR, 1.10; 95% CI, 1.01~1.19; p=0.01) were significantly associated with oxygen desaturation. Receiver operator characteristic (ROC) analysis showed that an absolute increment in pulse rate of 16/min gave optimal discrimination between desaturated and not desaturated patients after 6MWT. Conclusion: Pulse rate increment and diffusion capacity can predict exertional oxygen desaturation in stable COPD patients with moderate to severe airflow obstruction.

  • 초미세먼지 (particulate matter 2.5, $PM_{2.5}$)는 분진의 입경이 2.5 이하의 보다 작은 크기의 미세한 입자들을 말하는데, 미세먼지와 달리 대기 중에서 제거가 어렵고 기도나 코 점막에서 걸러지지 않으며, 호흡 시 폐포까지 직접 침투하기 때문에 장기간 노출될 경우, 폐 기능 감소, COPD (chronic obstructive pulmonary disease) 증가, 폐암 발생증가가 있다고 알려져 있다. 현재 국내외에서 초미세먼지에 대해 다양한 연구가 이루어지고 있는데, 초미세먼지의 농도는 기상인자 (풍속, 강우량, 일사량 등)에 영향을 받는 것으로 알려져 있으며, 이산화질소, 오존, 이산화황, 미세먼지 등 대기물질의 농도에도 영향을 받는 것으로 알려져 있다. 특히 우리나라는 점차 증가하고 있는 자동차 수나 오염원으로 인한 초미세먼지외에도 중국으로부터 유입되는 초미세먼지 또한 고려되어야 하는 대상이므로 기상인자 중 풍향과 풍속 또한 어느 정도 큰 영향을 미칠 것으로 판단되며 인접 지역에 대한 영양 또한 고려되어야 할 것이다. 본 연구에서는 초미세먼지 농도에 영향을 미치는 유의한 대기물질 및 기상자료와 초미세먼지 농도의 지역적 특성을 고려한 공간자기상관 행렬에 기초한 공간패널모형을 소개하였고 이를 서울 25개 구에서 관측된 초미세먼지 자료에 적용하였다. 또한 초미세먼지와 대기오염물질의 농도를 통해 서울시에서 발생한 호흡기 질환 환자 수를 분석하여 그의 위해성을 확인하였다.

  • 연구배경 및 목적 : 기류가역성의 유무와 정도의 평가는 기도질환 환자의 진단 및 치료에 있어서 매우 중요하지만, 기관지확장제 사용 후 기류 가역성을 관찰하기 위한 적절한 폐기능 검사 시간과 폐활량 측정치의 변화에 대한 연구는 매우 적다. 따라서 본 연구는 기관지확장제 사용 후 시간에 따른 폐활량 측정치의 변화를 분석하고자 하였다. 방 법 : 천식 환자 15명을 대상으로 salbutamol $200{\mu}g$을 일 회 흡입 후 15, 30, 45, 60분에 mini-Wright 유량측정기 및 폐활량검사를 이용하여 기관지확장제 반응을 측정하였다. 결 과 : $FEV_1$ 과 FVC의 평균값은 기관지확장제 사용 후 60분에 가장 높게 관찰 되었다. 폐활량 측정치 및 mini-Wright유량측정계의 두 측정치에서 PEF의 평균값은 기관지확장제 사용 후 45분에 가장 높게 관찰되었다. 결 론 : 이상의 결과로서 기류폐색이 의심되는 환자에서 기류가역성을 평가할 때 salbutamol 사용 후 15분 보다는 45분 내지 60분에 PEF 또는 $FEV_1$을 측정하는 것이 기관지확장제 반응을 적절히 평가할 것으로 사료된다.

  • Objectives: In this study, an evaluation of the working environment of furnace workers was performed and the work-relatedness of the occupational diseases were examined Methods: In this study, two electric furnaces at a single casting business site producing manganese-based iron alloy were selected, and occupational exposures to hazardous substances were evaluated for furnace workers and furnace worker assistants. Results: As a result, total dust concentration were $0.407{\sim}3.001mg/m^3$ and respirable dust concentration were $0.196{\sim}0.584mg/m^3$. The highest concentration of crystalline silica was $0.079mg/m^3$ In the case of Masato and Sosuckwhoi crystalline silica, they contained 90.85% and 4.17% respectively. Manganese concentration was the highest at a $0.205mg/m^3$ maximum. The average of black carbon is $11.56{\mu}g/m^3$ and the maximum concentration is $604.23{\mu}g/m^3$. PAHs concentration was the highest at a $78.301{\mu}g/m^3$ of naphthalene. The concentration of carbon monoxide was 18.82 ppm(total average 3.89 ppm) during pouring, and the maximum is 131 ppm. The formaldehyde concentration was 0.003 to 0.007 ppm. Conclusions: It seems that conditions in the past were worse, since casting has recently been performed only twice per day for about 20 minutes, reducing the amount of pouring, and local exhaust systems have been installed one-by-one. In addition, it was judged that the past exposure levels were higher considering the points measured on the back-side due to the risk of damage to the individual samples. It was found that operators could be exposed to high concentrations of crystalline silica, and that they were also exposed to high concentrations of metal(fume) and carbon monoxide during pouring. Therefore, there is a risk that occupational diseases such as lung cancer and COPD may occur with long-term work in such a process.

  • Background: Chest tube drainage (CTD) is an indication for the treatment of pneumothorax, hemothroax and is used after a thoracic surgery. But, in the case of incomplete lung expansion, and/or persistent air leak from CTD, medical or surgical thoracoscopy or, if that is unavailable, limited thoracotomy, should be considered. We evaluate the efficacy of bronchoscopic injection of ethanolamine to control the persistent air leak in patients with CTD. Methods: Patients who had persistent or prolonged air leak from CTD were included, consecutively. We directly injected 1.0 mL solution of 5% ethanolamine oleate into a subsegmental or its distal bronchus, where it is a probable air leakage site, 1 to 21 times using an injection needle through a fiberoptic bronchoscope. Results: A total of 15 patients were enrolled; 14 cases of spontaneous pneumothorax [idiopathic 9, chronic obstructive pulmonary disease (COPD) 3, post-tuberculosis 2] and one case of empyema associated with broncho-pleural fistula. Of these, five were patients with persistent air leak from CTD, just after a surgical therapy, wedge resection with plication for blebs or bullae. With an ethanolamine injection therapy, 12 were successful but three (idiopathic, COPD and post-tuberculosis) failed, and were followed by a surgery (2 cases) or pleurodesis (1 case). Some adverse reactions, such as fever, chest pain and increased radiographic opacities occurred transiently, but resolved without any further events. With success, the time from the procedure to discharge was about 3 days (median). Conclusion: Bronchoscopic ethanolamine injection therapy may be partially useful in controlling air leakage, and reducing the hospital stay in patients with persistent air leak from CTD.

  • 연구배경: 만성폐쇄성폐질환의 대부분은 흡연과 연관되어 발생하지만 흡연자의 약 10~20%에서만 만성폐쇄성폐 질환이 발생하는 현상은 질환의 발생에 개체의 유전적인 소인이 관여함을 시사한다. 저자들은 ${\alpha}1-antitrypsin$ 단백질을 암호화하는 SERPINA1 유전자의 다형성에 따른 만성폐쇄성폐질환의 위험도를 조사하였다. 방 법: 경북대학교병원 호흡기내과에서 만성폐쇄성폐질환으로 진단 받은 93명의 환자와 112명의 정상인을 대상으로 하였다. SERPINA1 유전자의 $M1_{val}$, $M1_{Ala}$, M2, S와 Z 대립유전자(allele)는 중합효소연쇄반응과 restriction fragment length polymorphism을 이용하여 조사하였다. 결 과: 환자군과 대조군 모두에서 S 및 Z allele은 없었으며, $M1_{Val}$ allele의 빈도는 환자군에서 유의하게 낮았다(73.6% vs. 82.7%, p=0.03). $M1_{Val}/M1_{Val}$ 유전자형인 경우에 비해 M2 혹은 $M1_{Ala}$ allele을 갖는 유전자형인 경우 만성 폐쇄성폐질환의 대응비는 1.86 (95% CI: 1.02~3.41, p=0.04)으로 유의하게 높았다. M2 allele 갖는 유전자형인 경우 대응비는 1.77 (95% CI: 0.96~3.27, p=0.07)이었으며, 연령에 따라 구분한 경우 64세 미만에서는 M2 allele을 갖는 경우 대응비가 3.09 (95% CI: 1.16~8.21, p=0.02)로 유의하게 높았다. 결 론: SERPINA1 유전자의 유전자형은 만성폐쇄성폐질환의 위험도를 결정하는 인자로 생각되나, 보다 많은 예를 대상으로 한 연구가 필요할 것으로 생각된다.

  • Background: MicroRNAs (miRNAs) have demonstrated their potential as biomarkers for lung cancer diagnosis. In recent years, miRNAs have been found in body fluids such as serum, plasma, urine and saliva. Circulating miRNAs are highly stable and resistant to RNase activity along with, extreme pH and temperatures in serum and plasma. In this study, we investigated serum miRNA profiles that can be used as a diagnostic biomarker of non-small cell lung cancer (NSCLC). Methods: We compared the expression profile of miRNAs in the plasma of patients diagnosed with lung cancer using an miRNA microarray. The data from this assay were validated by quantitative real-time PCR (qRT-PCR). Results: Six miRNAs were overexpressed and three miRNAs were underexpressed in both tissue and serum from squamous cell carcinoma (SCC) patients. Sixteen miRNAs were overexpressed and twenty two miRNAs were underexpressed in both tissue and serum from adenocarcinoma (AC) patients. Of the four miRNAs chosen for qRT-PCR analysis, the expression of miR-23a was consistent with microarray results from AC patients. Receiver operating characteristic (ROC) curve analyses were done and revealed that the level of serum miR-23a was a potential marker for discriminating AC patients from chronic obstructive pulmonary disease (COPD) patients. Conclusion: Although a small number of patients were examined, the results from our study suggest that serum miR-23a can be used in the diagnosis of AC.
