Several studies about hospital malnutrition have been reported that about more than 40% of hospitalized patients are having nutritional risk factors and hospital malnutrition presents a high prevalence. People in a more severe nutritional status ended up with a longer length of hospital stay and higher hospital cost. Nutrition screening tools identify individuals who are malnourished or at risk of becoming malnourished and who may benefit from nutritional support. For the early detection and treatment of malnourished hospital patients , few valid screening instruments fur Koreans exist. Therefore, the aim of this study was to develop a simple, reliable and valid malnutrition screening tool that could be used at hospital admission to identify adult patients at risk of malnutrition using medical electrical record data. Two hundred and one patients of the university affiliated medical center were assessed on nutritional status and classified as well nourished, moderately or severely malnourished by a Patient-Generated subjective global assessment (PG-SGA) being chosen as the 'gold standard' for defining malnutrition. The combination of nutrition screening questions with the highest sensitivity and specificity at prediction PG-SGA was termed the nutrition screening index (NSI). Odd ratio, and binary logistic regression were used to predict the best nutritional status predictors. Based on regression coefficient score, albumin less than 3.5 g/dl, body mass index (BMI) less than $18.5kg/m^2$, total lymphocyte count less than 900 and age over 65 were determined as the best set of NSI. By using best nutritional predictors receiver operating characteristic curve with the area under the curve, sensitivity and 1-specificity were analyzed to determine the best optimal cut-off point to decide normal or abnormal in nutritional status. Therefore simple and beneficial NSI was developed for identifying patients with severe malnutrition. Using NSI, nutritional information of the severe malnutrition patient should be shared with physicians and they should be cared for by clinical dietitians to improve their nutritional status.

Objectives: We developed the predictive model for the incidence of colon cancer by utilizing the health screening data of the National Health Insurance in Korea. We also explored the characteristics of the high risk group for colon cancer. Methods: The predictive model was used to determine those people who have a high risk for colon cancer within 2 years of their NHI health screening, and we excluded the people who had already been treated for cancer or who were cancer patient. The study population is the insured of the NHI, aged 40 or over and they had undergone health screening from the year 2000 to 2004, according to NHI health screening formula. We performed logistic regression analysis and used SAS Enterprise Miner 4.1. Results: This study shows that there exists a higher rate of colon cancer in males than females. Also, for the population in their 60s, the incidence rate of colon cancer is much higher by 5.36 times than that for those people in their 40s. Amongst the behavioral factors, heavy drinking is the most important determinant of the colon cancer incidence (7.39 times in males and 21.51 times in females). Conclusions: Our study confirms that the major influencing factors for the incidence of colon cancer are drinking, lack of exercise, a medical history of colon polypus and a family history of colon cancer. As a result, we can choose the group that is at a high risk for colon cancer and provide customized medical information and selective management services according to their characteristics.

Background: Breast cancer is the commonest type of cancer among women, and in Malaysia 50-60% of the new cases are being detected at late stages. Do age, education level, income, ethnicity, relationship with breast cancer patients and knowledge of breast cancer risk factors influence breast screening practices? This study revealed interesting but significant differences. Objectives: To assess the knowledge of breast cancer risk factors and early detection measures among women in a high risk group. Materials and Methods: A cross sectional survey of one hundred and thirty one women relatives of breast cancer patients was carried out. Participants were selected through purposive sampling, during hospital visits. A self-administered questionnaire was used for data collection. Results: The majority of the respondents (71%) had poor knowledge of the risk factors for breast cancer. Income, relationship with a patient and practise of breast cancer screening predicted performance of mammography, $R^2$=0.467, F=12.568, p<0.0001. Conclusions: The finding shows inadequate knowledge of breast cancer risk factors and poor cancer screening practise among women with family history of breast cancer. Poor knowledge and practise of breast screening are likely to lead to late stage presentation of breast cancer disease. Some important predictors of breast cancer screening behaviour among women with positive family history of breast cancer were identified. An understanding of the strengths and significance of the association between these factors and breast screening behaviour is vital for developing more targeted breast health promotion.

Objective : Post-traumatic stress disorder (PTSD) is a group of diseases that are observed in patients who had experienced a serious trauma or accident. However, some experienced it even after only a mild traumatic brain injury (TBI), and they are easily ignored due to the relatively favorable course of mild TBI. Herein, the authors investigated the incidence of PTSD in mild TBI using brief neuropsychological screening test (PTSD checklist, PCL). Methods : This study was conducted on patients with mild TBI (Glasgow coma scale ${\geq}13$) who were admitted from January 2012 to December 2012. As for PCL, it was done on patients who showed no difficulties in communication upon admission and agreed to participate in this study. By using sum of PCL, the patients were divided into high-risk group and low-risk group. PTSD was diagnosed as the three major symptoms of PTSD according to the Diagnostic and Statistical Manual of Mental Disorders, fourth-edifion. Results : A total of 314 TBI patients were admitted and 71 of them met the criteria and were included in this study. The mean age was 52.9 years-old (range : 15--94). The mean PCL score was 28.8 (range : 17--68), and 10 patients were classified as high-risk group. During follow-up, 2 patients (2.7%) of high risk group, were confirmed as PTSD and there was no patient who was suspected of PTSD in the low-risk group (p=0.017). Conclusion : PTSD is observed 2.8% in mild TBI. Although PTSD after mild TBI is rare, PCL could be considered as a useful tool for screening of PTSD after mild TBI.

Objectives : DAMA cases were analyzed to examine what the main casual factors of DAMA were and how to deal with these cases effectively in hospital with the DAMA interdisciplinary team including medical social worker whose role is to perform psycho-social assessment, family counsel, to evaluate family's DAMA need. Patients and Methods : The content analysis of medical record and social work record were reviewed in 37 cases referred by medical doctor to DAMA team. These cases were reported by patients' self discharge request or family's request for discharge from September 1998 to February 2000. The DAMA team consists of Assistant Director of Hospital as team leader, medical staff in-charge, social worker, QI nurse, other staff members who are not involved in direct treatment for patient, and administrative clerk. Results : The results of content analysis are as follows : 1) The most causal factors of DAMA consist of combination of more than 2 factors. 2) The major decision-maker is revealed to be son and daughter of patient. 3) In 59.4% of cases, family was not informed of patients' prognosis, alternatives, the consequence of DAMA at all. 4) In cases of DAMA report, the rapid intervention of social worker is carried out. Conclusion : In this study, we propose the interdisciplinary team approach to make decision legitimately and ethically for DAMA. The suggestions from this study are as follows : 1) To deal with DAMA case properly, the interdisciplinary team approach should be considered. 2) The criteria for DAMA case should be formed carefully. For the explicit selection of DAMA case, preliminary system for high-risk patient screening is recommended. 3) The medical social worker is available for the psycho-social problems of the patient once family members. For the effective family counselling, discharge planning and nursing home placement, the participation of medical social worker should be mandatory.

In view of funding crunches and inadequate manpower in cytology in developing countries like India, single lifetime screening for cervical cancer has been suggested. In this study, an attempt was made to cscreening to make it more effective for early detection. Cytological data were derived from the ongoing routine cervical cytology screening program for women attending Gynaecology Out Patient Department of Queen Mary's Hospital of K.G.Medical University, Lucknow, India during a span of 35 years (April 1971 - December 2005). Cervical smears in a total of 38,256 women were cytologically evaluated. The frequencies of squamous intraepithelial lesions of cervix (SIL) and carcinoma cervix were found to be 7.0% and 0.6%, respectively, in the series. Predisposing factors related to cervical carcinogenesis were analyzed in detail to establish the most vulnerable groups of women for single life time screening. The incidence of SIL and carcinoma cervix was found to be maximal in women above the age of 40 years irrespective of parity and in multiparous women (with three or more children) irrespective of age. The incidence of cervical cytopathologies was significantly higher in symptomatic women, the frequency of SIL being alarmingly higher in women complaining of contact bleeding and that of carcinoma cervix in older women with postmenopausal bleeding. It is consequently felt that single life time screening must include the three groups of women delineated above. Such selective screening appears to be the most economical, cost effective and feasible approach to affordably control the menace of cervical cancer in developing countries like India.

MDCT의 등장과 함께 병적 증상이 없는 개인이 조기검진을 위해 CT검사를 하는 예가 꾸준히 증가하고 있다. 이러한 검사의 임상적 효용성과 방사선에 의한 암 발생위험에 대한 여러 가지 논란을 살펴보았다. 1. 저선량흉부CT(LDCT)를 이용한 폐암의 조기 검진 효용성을 보기 위해 설계된 무작위배정대조검사(randomized controlled trial)인 NLST(National Lung Screening Trial)의 분석 결과, CT선별검사가 선별검사를 하지 않은 그룹의 사망률 1.67%를 1.33%로, 20% (p=0.004) 감소시키는 것으로 나타났다. CT선별검사군에서 양성결과를 보인 사람의 96.4%는 위양성(false-positive)이었다. 그리고 방사선에 의한 폐암의 ERR (excess radiation risk)은 다른 고형암과는 달리 나이와 함께 감소하지 않으며, 더욱이 흡연 위험과 방사선 위험이 상승작용을 하여 폐암 검진 대상인 고위험군에게 더욱 위험할 수 있는 것으로 평가되었다. 따라서 방사선에 의한 위험이 NLST에서 관측한 이득을 상쇄할 수도 있다. 아직은 최적의 전략이 확립되지 않은 상태이므로 임상에서 광범위하게 적용하기에는 한계가 있다. 2. 대장CT검사(CT colonography)는 10 mm보다 큰 용종의 검출에는 정확도가 뛰어나지만 이보다 작은 경우에는 민감도와 특이도가 급격히 감소하고, 용종이 발견되어 제거하고자 하는 경우 다시 기존의 대장내시경을 이용해야 하는 불편함이 있다. 현재 대장CT검사 1회 시행의 평균유효선량은 약 8-10 $mS{\nu}$로 보고되어, 만약 이 검사가 많은 사람들을 대상으로 일상적으로 행해지면 공중보건에 영향을 미칠 수 있다. 따라서 집단검진 방법으로 정착하기 위해서 는 용종 크기 6-10 mm 범위에서 높은 민감도와 특이도를 확립하고, 하제를 사용하지 않는 방법을 개발하여야 하며, 선량을 더 감소시킬 수 있는 최적화된 전략을 세워 표준화하여야만 한다. 3. 전신CT검사는 그 효용성이 검증된 선행연구가 없는 상태이다. 이 검사는 약 90%의 검사자들에게서 최소한 하나 이상의 이상소견을 확인하였지만 그 중 약 2%만이 임상적으로 중요한 질환으로 판명되었다. 전신CT검사 1회 시행으로 인한 평균유효선량은 약 12 $mS{\nu}$이며 45세부터 75세까지 매년 검사를 받는 경우 LAR (lifetime attributable risk)이 1.9%로 보고되었다. 현재 의학계의 어떤 단체도 이 검사를 권고하고 있지 않다. 현재까지 CT선별검사는 정당화에 대한 충분한 논의를 위해 심도 있는 다양한 연구가 필요하며 최적화된 프로토콜이 확립된 후 이용하는 것이 바람직하다.

Purpose: Nutritional status and support in critically ill patients are important factors in determining patient recovery and prognosis. The aim of this study was to analyze the early nutritional status and the methods of nutritional support in critically ill patients with acute poisoning and to evaluate the effect of nutritional status on prognosis. Methods: A retrospective study was conducted in tertiary care teaching hospital from January 2018 to December 2020. in an emergency department of university hospital, 220 patients who were stayed more than 2 days of poisoning in intensive care unit were enrolled. Results: 155 (70.5%) of patients with acute poisoning had low-risk in nutritional risk screening (NRS). Patients with malignancy had higher NRS (low risk 5.2%, moderate risk 18.5%, high risk 13.2%, p=0.024). Patients of 91.4% supplied nutrition via oral route or enteral route. Parenteral route for starting method of nutritional support were higher in patients with acute poisoning of herbicide or pesticide (medicine 3.2%, herbicide 13.8%, pesticide 22.2%, p=0.000). In multivariate logistic regression analysis, herbicide or pesticide intoxication, higher risk in NRS and sequential organ failure assessment over 4.5 were affecting factor on poor recovery at discharge. Conclusion: NRS in patients intoxicated with herbicide or pesticide were higher than that in patients intoxicated with medicine intoxication. Enteral nutrition in patients intoxicated with herbicide or pesticide was less common. Initial NRS was correlated with recovery at discharge in patient with intoxication. It is expected to be helpful in finding patients with high-risk nutritional status in acute poisoning patients and establishing a treatment plan that can actively implement nutritional support.
