The problems of health in poor peoples are various and difficult things to solve it. They are highly susceptible to chronic disease because of bad environment and It is hard to access to medical services because of their Socio-demographic status. Therefore, it is important to address the problem of prevention of chronic disease and health promotion aspect. The purpose of this study was to determine the relationships among the health status, health behaviors and health practices of poor people in urban slum area. The subject of this study were 298 poor peoples who live in poor area in Daegu metropolitan city and they were asked to answer the survey questionnaires modified for Korean from behavioral risk factor surveillance system of Centers for Disease Control and Prevention USA. The result of the study were as follows； (1) There were significant relationships between health status (prevalence of chronic disease and perceived general health) and socio-demographic factor such as occupation, existence of spouse, number of family educational level, type of medical security. (2) There were some relationships between health risk behaviors such as smoking, drinking and obesity and health status of subject especially in female obesity.(3) There were relationships among health concern activity, prevalence of chronic disease and some social factor such as educational level and occupation. (4) There were relationships among health practice, health concern activity, health status and socio-demographic factors of subject. This study suggest that health status, socio-demographic status, health concerns and health promotion activity of study populations were associated and It is very important things supporting the poor people in the level of community and nation to practice healthy behaviors themselves.

Purpose: The study was done to compare quality of life by gender, and to identify factors which explain quality of life in individuals with coronary artery disease. Methods: For the survey, 91 individuals (53 men and 38 women) agreed to participate in the study. Cardiovascular risk factors, systolic blood pressure, body mass index, total cholesterol, triglyceride, high density lipoprotein-cholesterol, and low density lipoprotein-cholesterol, health behavior as well as quality of life, were measured. Descriptive statistics, t-test, correlation and hierarchical multiple regression with SPSS WIN 12.0 were used to analyze the data. Results: Significant gender differences were found for education, smoking status, chronic disease, perceived health status, and quality of life within sub-dimensions. Hierarchical regression analysis showed gender (men), age, perceived health status, cardiovascular risk scores, and health behaviors together explained 40.2% (adjusted $R^2$) of variance in quality of life. Conclusion: As the factors explaining quality of me in individuals with coronary artery disease have been identified as gender (men), age, perceived health status, and health behaviors, health promotion programs designed for this population should focus on these factors for effective behavioral modification, and consequent improvement in quality of life.

Objective : Burr hole drainage has been widely used to treat chronic subdural hematoma (CSDH). However, the incidence of recurrent CSDH varies from 3.7 to 30% after surgery. The authors attempted to elucidate the risk factors associated with the recurrence of CSDH in one burr hole drainage technique. Methods : A total of 255 consecutive cases who underwent one burr hole drainage for CSDH were included in this study. Twenty-four patients (9.4%) underwent a repeated operation because of the recurrence of CSDH. We analyzed retrospectively the demographic, clinical and radiologic factors associated with the recurrence of CSDH. Results : In this study, two risk factors were found to be independently associated with the recurrence of CSDH. The incidence of CSDH recurrence in the high- and mixed-density groups was significantly higher than those in the low- and iso-density groups (p<0.001). Bleeding tendency such as in leukemia, liver disease and chronic renal failure was also significantly associated with recurrence of CSDH (p=0.037). Conclusion : These results suggest that high- and mixed- density shown on computed tomographic scan was closely relates with a high incidence of recurrence. Therefore, the operation could be delayed in those cases unless severe symptoms or signs are present. Reoperation using the previous burr hole site is a preferred modality to treat the recurrent CSDH.

Background: Hepatic steatosis measured with controlled attenuation parameter (CAP) using transient elastography predicts metabolic syndrome in the general population. We investigated whether CAP predicted metabolic syndrome in chronic kidney disease patients. Methods: CAP was measured with transient elastography in 465 predialysis chronic kidney disease patients (mean age, 57.5 years). Results: The median CAP value was 239 (202-274) dB/m. In 195 (41.9%) patients with metabolic syndrome, diabetes mellitus was more prevalent (105 [53.8%] vs. 71 [26.3%], P < 0.001), with significantly increased urine albumin-to-creatinine ratio (184 [38-706] vs. 56 [16-408] mg/g Cr, P = 0.003), high sensitivity C-reactive protein levels (5.4 [1.4-28.2] vs. 1.7 [0.6-9.9] mg/L, P < 0.001), and CAP (248 [210-302] vs. 226 [196-259] dB/m, P < 0.001). In multiple linear regression analysis, CAP was independently related to body mass index (${\beta}=0.742$, P < 0.001), triglyceride levels (${\beta}=2.034$, P < 0.001), estimated glomerular filtration rate (${\beta}=0.316$, P = 0.001), serum albumin (${\beta}=1.386$, P < 0.001), alanine aminotransferase (${\beta}=0.064$, P = 0.029), and total bilirubin (${\beta}=-0.881$, P = 0.009). In multiple logistic regression analysis, increased CAP was independently associated with increased metabolic syndrome risk (per 10 dB/m increase; odds ratio, 1.093; 95% confidence interval, 1.009-1.183; P = 0.029) even after adjusting for multiple confounding factors. Conclusion: Increased CAP measured with transient elastography significantly correlated with and could predict increased metabolic syndrome risk in chronic kidney disease patients.

Background: A diabetic foot is the most common cause of non-traumatic lower extremity amputations (LEA). The study seeks to assess the risk factors of amputation in patients with diabetic foot ulcers (DFU). Methods: The study was conducted on 351 patients with DFUs from January 2010 to December 2018. Their demographic characteristics, disease history, laboratory data, ankle-brachial index, Wagner classification, osteomyelitis, sarcopenia index, and ulcer sizes were considered as variables to predict outcome. A chi-square test and multivariate logistic regression analysis were performed to test the relationship of the data gathered. Additionally, the subjects were divided into two groups based on their amputation surgery. Results: Out of the 351 subjects, 170 required LEA. The mean age of the subjects was 61 years and the mean duration of diabetes was 15 years; there was no significant difference between the two groups in terms of these averages. Osteomyelitis (hazard ratio [HR], 6.164; 95% confidence interval [CI], 3.561-10.671), lesion on percutaneous transluminal angioplasty (HR, 2.494; 95% CI, 1.087-5.721), estimated glomerular filtration rate (eGFR; HR, 0.99; 95% CI, 0.981-0.999), ulcer size (HR, 1.247; 95% CI, 1.107-1.405), and forefoot ulcer location (HR, 2.475; 95% CI, 0.224-0.73) were associated with risk of amputation. Conclusion: Osteomyelitis, peripheral artery disease, chronic kidney disease, ulcer size, and forefoot ulcer location were risk factors for amputation in diabetic foot patients. Further investigation would contribute to the establishment of a diabetic foot risk stratification system for Koreans, allowing for optimal individualized treatment.

Purpose : Preeclampsia(PE) is a pregnancy-specific disease which is characterized by hypertension and proteinuria. This disease occurs in about 2-8 % of pregnancies in developing countries and remains among the major causes of maternal and neonatal mortality and morbidity throughout the world. Although the causes of PE are not fully understood, the infection has been considered as the main risk factor for this diseases. Periodontal disease may provide a chronic burden of endotoxin and inflammatory cytokines and the disease has been considered as risk factors of systemic illnesses including cardiovascular disease, atherosclerosis, and cerebrovascular ischemia. So, studies performed over the last 15 years have suggested that periodontal disease may be associated with adverse pregnancy outcomes such as PE. However, this association has not been found in all populations. The aim of this review article was to evaluate whether periodontal status and the presence of specific periodontal pathogens may influence the incidence of PE. Methods : Many research articles searched at the electronic databases(MEDLINE; 2000 to July 2017) including search term as periodontal disease and preeclampsia. Result : There were 10 case-control studies and 5 cohort studies meeting our inclusion criteria. The results showed that maternal periodontitis (adjusted odds ratio: 1.5 to 9.3) was associated with preeclampsia in 15 epidemiological studies. Conclusion : It is clear that maternal periodontitis is a risk factor associated with preeclampsia, emphasizing the importance of periodontal care in prenatal programs.

Purpose: The purpose of this study is to identify risk factors of accidental falls by age in the Korean elderly. Methods: The study subjects included 10,242 community-dwelling elders aged 65 or over. The data were analyzed by logistic regression analysis. Results: The risk factors of accidental falls in the younger old group (aged 65~74) include fear of falling (OR=16.28, 95% CI: 12.03~22.03), depression (OR=1.24, 95% CI: 1.06~1.44), and hearing impairment (OR=1.20, 95% CI: 1.01~1.43). The risk factors of accidental falls in the older old group (aged 75~84) include fear of falling (OR=11.54, 95% CI: 7.04~18.93), muscle strength (OR=1.36, 95% CI: 1.15~1.60), number of chronic disease (OR=1.65, 95% CI: 1.09~2.50), and presence of spouse (OR=1.27, 95% CI: 1.06~1.51). The risk factors of accidental falls in the oldest old group (aged 85 years old or older) include fear of falling (OR=8.05, 95% CI: 1.85~34.98) and exercise (OR=2.91, 95% CI: 1.36~6.24). Fear of falling is defined as a common factor in the all age groups. Conclusion: Different strategies should be developed for age groups to prevent elderly falls with understanding of contributing factors of falls in each group.

Due to its efficacy and tolerability, low dose oral methotrexate (MTX) therapy has been widely used for treatment of rheumatoid arthritis (RA). However, it can rarely cause serious, life-threatening hematologic toxicities, such as pancytopenia. We report here on two patients with chronic kidney disease (CKD), who developed severe pancytopenia after 5 years (cumulative dose 1,240 mg) and 4 years (cumulative dose 1,320 mg) of low dose MTX therapy for treatment of RA, respectively. Both patients presented with renal insufficiency, hypoalbuminemia, concurrent use of nonsteroidal anti-inflammatory drugs, and elevated mean corpuscular volume of red blood cells (RECs), all of which are known as risk factors of MTX-induced pancytopenia. Despite receiving treatment, which included REC and platelet transfusions, antibiotic therapy, granulocyte colony stimulating factor, and leucovorin rescue, one patient died of sepsis. Based on our case study, prompt investigation of risk factors associated with MTX toxicity is required for all patients receiving MTX therapy. MTX treatment, even at a low dose, should be discontinued in patients with advanced CKD.

연구배경: 골다공증은 만성폐쇄성폐질환 환자의 중요한 동반질환 중 하나이다. 저자들은 COPD 환자에서 골다공증의 유병률과 위험인자를 알아 보고자 하였다. 방 법: 안정 상태인 COPD 환자 51명과 이들과 나이와 성별을 일치시킨 대조군 41명에서 요추골과 대퇴골의 골밀도를 측정하였다. 임상기록과 검사결과를 검토하여, COPD 환자에서 골다공의 위험인자를 분석하였다. 결 과: COPD 환자에서, T점수가 -2.5 이하인, 골다공증의 유병률은 47%였고, 대조군에서 32%였다. 특히 대퇴골목의 T점수를 기준으로 한 골다공증의 유병률은 COPD 환자에서 대조군에 비해 유의하게 높았다(26% vs. 5%; p=0.006). COPD 환자의 요추와(p=0.025) 대퇴골목의 평균 T 점수는 대조군보다 유의하게 낮았다(p=0.001). COPD 환자에서 $FEV_1$의 정상예측치에 대한 비율과(p=0.019; odds ratio [OR], 0.955; 95% confidence interval [CI], 0.919-0.993) 연령이 골다공증 발생과 관련된 독립적인 위험인자였다(p=0.024; OR, 1.144; 95% CI, 1.018-1.287). 결 론: COPD 환자에서 골다공증의 유병률은 연령과 성별을 일치시킨 대조군보다 높다. 특히 대퇴골의 T점수가 요추보다 COPD 환자와 대조군의 골밀도의 차이를 더 분명하게 보여 주었다. COPD 환자에서 $FEV_1$이 낮을수록, 나이가 많을수록 골다공증 발생 위험이 크게 증가한다.
