1.Purpose Stroke is the most frequent cause of mortality and morbidity rate in Korea with ischemic heart disease and cancer. Recent recurrence rate of stroke is high, but little attention had been given to the features of its' cause. The purpose of this studies is to examine the hematologic states in Korean normal adults through premature-examination of stroke(PES). 2.Method The study group consisted of 326 cases that they had no significant results by CT through premature examination of stroke(PES) in Cheonan oriental hospital of Daejeon university. We tested RBC, hemoglobin, hematocrit, WBC, PT, PTT, PLT, total protein, albumin, total bilirubin, direct bilirubin, GOT, GPT, $\gamma$-GTP, total cholesterol, triglyceride, HDL-C, glucose, BUN, creatinine, Na, K and evaluated by cross sectional study. 3.Result In the PES, there were many patients with low RBC(11%), shorten PT(26.7%), delayed PTT(19.3%), high TP, GPT, ${\gamma}$ -GTP(respective1y 16.9%, 14.4%, 13.5%), high cholesterol level and triglyceride level(respectively 18.7%, 28.2%). We didn't found significant cases in hemoglobin, hematocrit, WBC, PLT, albumin, total bilirubin, direct bilirubin, GOT, HDL-C, glucose, BUN, creatinine, Na, K. 4.Conclusion In this study, we demonstrated that short PT, high triglyceride level are special views in PES. Also prospective studies are needed continuously to search the preventing methods of the CVA.

Insufficient vitamin D intake is a major health problem around the world. Recently, many studies have suggested that vitamin D intake may influence insulin resistance. However, little is known about the association between vitamin D and diabetes mellitus. The aim of this study was to investigate the association between serum 25-hydroxy vitamin D (25(OH)D) levels and diabetes mellitus in Korean adults. This study was a cross-sectional analysis of 3,686 participants of the Korean National Health and Nutrition Examination Survey (KNHANES) 2013~2014 aged 19 years and higher. The results showed that the mean serum 25-hydroxy vitamin D (25(OH)D) level in Korean adults was 16.77 ng/mL, and 74.2% of them had an insufficient serum 25-hydroxy vitamin D (25(OH)D) level (below 20 ng/mL). In normal and pre-diabetic groups, the serum 25-hydroxy vitamin D (25(OH)D) level significantly increased with age (P<0.001), but there was no significant difference relative to age in the diabetic group. Low vitamin D levels (25-hydroxy vitamin D < 10 ng/mL) were associated with increased fasting blood glucose levels, compared with optimal vitamin D levels (25-hydroxy vitamin D > 30 ng/mL), after adjusting for variables that may affect fasting blood glucose, but this result was not significant. In conclusion, although no significant association was observed between diabetes prevalence and vitamin D levels in this study, further studies are needed because the effect of vitamin D on diabetes remains controversial. This nutrient plays a crucial role in the body, and levels are insufficient in the Korean population.

Purpose: This study aims to determine obstetrics nurses knowledge, attitude, and practice about breast cancer and breast self-examination (BSE), and to contribute to the early detection of breast cancer during breastfeeding periods. Methods: For the survey, 163 individuals (obstetric nurses) were chosen by convenience sampling and agreed to participate in the study. Their knowledge, attitude, and practice about breast cancer and BSE. Results: Knowledge and attitude averaged $70.45{\pm}10.90$ (of 100) and $3.64{\pm}0.27$ (of 5), respectively. While most nurses (99%) recognized the importance of BSE, only 58.9% experienced BSE. BSE practice level averaged $8.35{\pm}1.96$ (of 12). Only 20.2% had recommended BSE to their clients. Practice level varied significantly for different marital status, breastfeeding experience, and education, while knowledge and attitude remained independent. Nurses who had experienced mammogram or breast ultrasonogram themselves scored higher in knowledge. Attitude was higher for nurses who received recommendation for BSE, performed BSE, received BSE education, or recommended BSE to clients. Practice level was higher for nurses who received BSE education or willing to perform BSE in future. Practice level had a positive correlation with attitude but no correlation to knowledge. Conclusion: Obstetric nurses need continuing education for practicing BSE. Practical BSE education can not only promote preventive behavior of nurses, but it can also improve the breast health management of obstetrical clients.

Background: We evaluated the association of blood pressure (BP) with blood levels of cadmium, lead, and cadmium and lead together (cadmium + lead) in a representative sample of adolescents from Korea. Methods: We used 2010-2016 data from the Korean National Health and Nutrition Examination Survey. This cross-sectional study enrolled adolescents aged at 10-18 years-old who completed a health examination survey and had blood measurements of lead and cadmium. The association of adjusted mean differences in diastolic and systolic BP with doubling of blood lead and cadmium were estimated by regression of BP against ${\log}_2$-transformed blood metals and their quartiles after covariate adjustment. Adjusted odds ratio for prehypertension were calculated for ${\log}_2$-transformed blood levels of lead and cadmium and their quartiles. Results: Our analysis of adolescents in Korea indicated that blood levels of lead and cadmium were not significantly associated with increased BP or risk of prehypertension. However, the cadmium + lead level was associated with prehypertension. Previous studies showed that blood levels of lead and cadmium were associated with increased BP and risk of hypertension in adult populations. We found no such association in Korean adolescents. Conclusion: We found that the cadmium + lead level was associated with prehypertension. The differences between adults and adolescents are because adolescents generally have lower levels of these blood metals or because adolescents only rarely have hypertension.

Objectives: In this study, both subjective and objective levels of oral health were used to identify the relationship between oral health inequalities. Methods: Korean National Health and Nutritional Examination Survey data from 2013 to 2015 were combined to create an analysis plan. Oral health questions categorized as subjective oral health conditions and oral health-related diseases used dental tissue disease status as data measured by the Community Periodical Index(CPI) and decayed, missing, filled teeth(DMFT) experience. Other data on oral health behaviors such as toothache experience, the frequency of toothbrush use, chewing problems, oral examination status, and unmet dental care needs were classified and analyzed according to the socioeconomic level. Data were analyzed using frequency and cross analyses, and the statistical significance level was set at 0.05. Results: It was found that higher the economic and educational level, better was the subjective oral health, lower the CPI, lower the experience of toothache, higher the frequency of toothbrush use, lower the number of people having chewing problems, and higher the frequency of oral checkups. Conclusions: Oral health inequality exists among social classes. It is suggested that continuous research and efforts be carried out to promote oral health while considering socioeconomic and educational levels. Further, active government efforts will be needed to address polarization by social class.

Background: It is important to investigate patient satisfaction to improve the quality of healthcare. Among the many factors that affect patient satisfaction, perceived health status has been considered as one of the major factors. Therefore, we investigated patient satisfaction through patient experience in outpatient settings according to perceived health status. Methods: This cross-sectional study using questionnaires of patient experience and perceived health status from the Korean National Health and Nutrition Examination Survey 2015 included 4267 people aged over 19 years who met the inclusion criteria. Perceived health status was classified into three: good, fair, and poor. Questions about patient experience consisted of four items: doctor spending enough time with patients, doctor providing easy-to-understand explanation, doctor giving opportunity to ask questions or raise concerns, and doctor involving patient in decisions about care or treatment. Patient experience was classified into two: satisfied and non-satisfied. A multivariate regression model was used to analyze the data. Results: In the good perceived health status group, level of satisfaction was 79.2%, 88.5%, 83.3% and 87.2%, respectively for the four items targeting patient experience. In the poor group, level of satisfaction was 76%, 84.9%, 79.5%, and 83.1%, respectively for the four items. In multivariate logistic regression analyses, the odds ratios of good perceived health status group were 1.775 (1.347-2.338), 1.946 (1.356-2.793), 1.652 (1.218-2.240), and 1.665 (1.193-2.323) compared with the poor group. Conclusion: Perceived health status is associated with patient satisfaction. In particular, the better the perceived health status, the better the patient satisfaction through patient experience.

This study was conducted to analyze the relationship between the levels of lead (Pb) exposure and cardiovascular disease (CVD) in Korean adult women. We used cross-sectional data on blood lead and self-reported diagnoses of ischemic heart disease (IHD), stroke and hypertension in a subsample of 1.821 adults 19 years and older who participated in the 2017 Korea National Health and Nutrition Examination Survey (KNHANES). CVD and blood Pb concentrations were analyzed through logistic regression analysis, and correlations between factors were confirmed using the pearson correlation coefficient. An increase of blood Pb was associated with an increased risk of IHD (OR 5.68, 95% CI 1.01-17.51) and hypertension (OR 3.37, 95% CI 2.24-5.07) only in women. Additionally, there was a correlation between blood Pb and nutrient intake. This suggest that blood Pb levels may be used as a key predictor of CVD development, and that women are more susceptable to IHD and hypertension associated with Pb exposure.

Background: Breast cancer is the most common type of cancer in women throughout the world. However, in comparison with Western women, it presents relatively early in women of Asian ethnicity. Early menarche, late menopause, use of OCP's, family history of benign or malignant breast disease, exposure to radiation and BMI in the under-weight range are well known risk factors for the development of breast cancer in premenopausal women. Early detection with the use of breast self-examination (BSE) and breast cancer screening programs can lead to a reduction in the mortality rates due to breast cancer. The aim of our study was to assess the risk factors for breast cancer among young women and to emphasize the importance of early screening among them. Materials and Methods: We conducted a cross-sectional study among women aged 18 to 25 using a self-administered questionnaire. Data was collected over a period of 6 months from June to December, 2014. A total of 300 young women selected randomly from Dow Medical College and various departments of Karachi University successfully completed the survey. Results: Respondents were 18-25 years of age (mean age=21.5). Out of the 300 young females, 90 (30%) had at least one risk factor, 90 (30%) had two, 40 (13%) had three, 8 (2.7%) had four, 2 (0.7%) had five while one female was found to have six positive risk factors for breast cancer. Some 66 women (22%) experienced symptoms of breast cancer such as non-cyclical pain and lumps. While 222 women (74%) had never performed breast self-examination, 22 (7.3%) had had a breast examination done by a health professional while 32 (10.7%) had participated in breast screening programs. A total of 223 (74.3%) women considered breast cancer screening important for young women. Conclusions: The percentage of young women with risk factors for breast cancer was found to be alarmingly high. Therefore, screening for breast cancer should start at an early age especially in high risk groups. Awareness about breast self-examination should be emphasized. Moreover, screening programs should be started to ensure early detection and reduction of mortality rates caused by breast cancer also in young Pakistani females.

Purpose: The purpose of this study is to evaluate the relationship between removable denture and depression. This study aims to investigate the relationship between depression and each group by dividing them into a group that were using removable dentures and a group that needed removable dentures but were not using removable dentures. Materials and methods: This study was conducted using raw data from the 7th Korea National Health and Nutrition Examination Survey (KNHNES). By using variables related to the state of the prosthesis and the need for prosthesis among oral examination data, the oral examination data were classified into two groups; group using removable denture and group in need of removable dentures. In addition, the variables of depression were classified into normal (0-4), mild depression (5-9), moderate depression (10-19), and severe depression (20-27) using the values of PHQ-9. For statistical analysis, logistic regression analysis was performed using SAS 9.4. Results: In the group in need of removable dentures, the risk of severe depression was statistically and significantly higher than the group using removable dentures. Conclusion: In patient who have lost multiple teeth, rehabilitation of the missing area with removable dental prosthesis is expected to decrease the occurrence of severe depression.

Background To minimize the inflammatory reaction and improve healing, a new modified dermal substitute composed of an atelocollagen, chondroitin-6-sulfate, and amniotic membrane (AM) was applied to full-thickness skin defects in a pig. Atelocollagen was extracted from bovine skin, and two modified dermal substitutes were generated according to the cross-linking type. Methods The AM-collagen dermal substitutes were characterized and compared with currently used dermal substitutes in a pig skin defect model. There were five experimental groups: dehydrothermal (DHT) cross-linking atelocollagen with the AM on the top (AM-DHT), DHT and chemical cross-linking atelocollagen with the AM on the top (AM-DHT/chemical), Terudermis, Integra, and AlloDerm. After $3{\times}3cm$ full-thickness skin defects on the back of a pig were created, each dermal substitutes dermal substitutes was randomly grafted on the defects. Two weeks after grafting, autologous partial-thickness skin was over-grafted on the neodermis. The take rate of the dermal substitutes, skin, and histological sections were all assessed at 1, 2, and 4 weeks postoperatively. Results More rapid healing and a higher take rate were evident in the AM-DHT and Terudermis groups. Histological examination revealed fewer inflammatory cells and more fibroblast hyperplasia in these two groups. Four weeks after surgery, the amount of newly formed collagen was significantly more appropriate in the AM-DHT group. Conclusions These observations provide supporting evidence that a newly developed amniotic-collagen dermal substitute may inhibit inflammatory reactions and promote wound healing.
