Objective : In this study, we focused on estimating the burden of premature death in Korea caused by smoking using the YLL(years of life lost due to premature death) measurement. Methods : First, we determined parameters: such as age-specific standard life expectancy, age on death, sex, and cause of death by analyzing the national death certificate data and life table collected during 1997. These were provided by the National Statistical Office. Secondly, we estimated the age group- specific years of life lost due to premature death by employing the standard expected years of life lost(SEYLL) measurement. Thirdly, the burden of premature death caused by smoking was estimated using the YLLs measurement which was developed by the global burden of disease study group. Fourthly, We calculated the risk related to smoking using the population attributable risk. Results : The following results were obtained in this study: 1) Premature death that is attributable to smoking in males could be prevented in 60.9%(513,582 person-year) by non-smoking. 2) The burden of premature death by smoking for female was prevented to 17.7%(513,582 person-year) by non-smoking. Conclusion : We found that the YLL method employed in this study was appropriate in quantifying the burden of premature death. This provides a rational basis for planning a national health policy regarding premature deaths caused by smoking and other related risk factors.

Objective : To estimate the burden of diseases in Korea especially caused by major cancers using the YLL(years of life lost due to premature death) measurement. Methods : First, we determined the parameters: such as age-specific standard life expectancy, age on death, sex, cause of death by analyzing the national death certificate data and life table collected during 1996 provided by the National Statistical Office. Secondly, we estimated the age group-specific YLL by employing standard expected years of life lost(SEYLL). Thirdly, final burden of disease due to premature death was estimated by using YLLs measurement which developed by global burden of disease study group. Results : The burden of premature death by cancer for male was attributed mainly to liver cancer(514.5 person-year), stomach cancer(436.4 person-year), and lung cancer(367.7 person-year). Each of these cancers was responsible for the loss of over 100 person-year based on our YLL measurement. The burden of premature death by cancer for female was attributed mainly to liver cancer(135.1 person-year), stomach cancer(252.1 person-year), and lung cancer(121.8 person-year). Each of these cancers was responsible for the loss of over 100 person year based on our YLL measurement. Conclusion : We found the YLL method employed in this study was appropriate to quantify the burden of premature death. Thereby, it would provide a rational bases to plan a national health policy regarding premature death caused by cancer.

Objectives: We examined the association between social expenditures of the local government and the mortality level in Korea, 2004 to 2010. Methods: We used social expenditure data of 230 local governments during 2004 to 2010 from the Social Expenditure Database prepared by the Korean Institute for Health and Social Affairs. Fixed effect panel data regression analysis was adopted to look for associations between social expenditures and age-standardized mortality and the premature death index. Results: Social expenditures of local governments per capita was not significantly associated with standardized mortality but was associated with the premature death index (decline of 1.0 [for males] and 0.5 [for females] for each expenditure of 100 000 Korean won, i.e., approximately 100 US dollar). As an index of the voluntary effort of local governments, the self-managed project ratio was associated with a decline in the standardized mortality in females (decline of 0.4 for each increase of 1%). The share of health care was not significant. Conclusions: There were associations between social expenditures of the local government and the mortality level in Korea. In particular, social expenditures per capita were significantly associated with a decline in premature death. However, the voluntary efforts of local governments were not significantly related to the decline in premature death.

Purpose: To investigate the effectiveness of transient intubation for surfactant administration and extubated to nasal continuous positive pressure (INSURE) for treatment of respiratory distress syndrome (RDS) and to identify the factors associated with INSURE failure in extremely premature infants. Methods: Eighty-four infants with gestational age less than 28 weeks treated with surfactant administration for RDS for 8 years were included. Perinatal and neonatal characteristics were retrospectively reviewed, and major pulmonary outcomes such as duration of mechanical ventilation (MV) and bronchopulmonary dysplasia (BPD) plus death at 36-week postmenstrual age (PMA) were compared between INSURE (n=48) and prolonged MV groups (n=36). The factors associated with INSURE failure were determined. Results: Duration of MV and the occurrence of BPD at 36-week PMA were significantly lower in INSURE group than in prolonged MV group (P<0.05), but BPD plus death at 36-week PMA was not significantly different between the 2 groups. In a multivariate analysis, a reduced duration of MV was only significantly associated with INSURE (P=0.001). During the study period, duration of MV significantly decreased over time with an increasing rate of INSURE application (P<0.05), and BPD plus death at 36-week PMA also tended to decrease over time. A low arterial-alveolar oxygen tension ratio (a/APO2 ratio) was a significant predictor for INSURE failure (P=0.001). Conclusion: INSURE was the noninvasive ventilation strategy in the treatment of RDS to reduce MV duration in extremely premature infants with gestational age less than 28 weeks.

To help the interpretation of causes of death, it is critical that the background incidence of factors contributing to death be recorded and archived. Information was gathered from the control groups of 19 rat carcinogenicity studies. All cases of death occurring within the 2-year period were reviewed. Out of 1124 males and 1084 females, 720 male (64.1%) and 689 female (63.6%) decedents were recorded. There was no difference in the probability of survival between two sexes. Analysis of factors contributing to death revealed that 400 males (48.7%) had neoplastic changes, 189 males (23.0%) had non-neoplastic lesions, and 232 males (28.3%) died from unknown causes. In females, these figures were 627 (76.4%), 62 (7.6%) and 132 (16.0%), for neoplastic, non-neoplastic and unknown findings, respectively. It could be suggested that the risk of death by non-neoplastic reasons was higher in the males than in the females, whereas females were more likely to be affected by tumours. In the neoplastic causes of death, pituitary tumours were the most common in both sexes, followed by mammary tumours in females, and haemopoietic tumours in males. In non-neoplastic cause of death, renal diseases were the most common in both sexes, followed by skin diseases and cardiovascular diseases in males, and skin diseases and poditis in males. A relatively large number of animals (28.3% in males and 16.0% in females) were found dead, without any significant clinical or histologically identifiable cause. Most of the animals with pituitary tumours were killed in extremis and the proportion of females (70.1%) being greater than males (46.8%). There were no case which died by accident, and also only minimal incidence which died by bleeding procedures.

Background: Cancer is recently one of the major concerns of the public health both in the world and Iran. To inform priorities for cancer control, this study estimated years of potential life lost (YPLL) and productivity losses due to cancer-related premature mortality in Iran in 2012. Materials and Methods: The number of cancer deaths by sex for all cancers and the ten leading causes of cancer deaths in Iran in 2012 were obtained from the GLOBOCAN database. The life expectancy method and the human capital approach were used to estimate the YPLL and the value of productivity lost due to cancer-related premature mortality. Results: There were 53,350 cancer-related deaths in Iran. We estimated that these cancer deaths resulted in 1,112,680 YPLL in total, 563,332 (50.6%) in males and 549,348 (49.4%) in females. The top 10 ranked cancers accounted for 75% of total death and 70% of total YPLL in the males and 69% for both death and YPLL in the females. The largest contributors for YPLL in the two genders were stomach and breast cancers, respectively. The total cost of lost productivity due to cancer-related premature mortality discounted at 3% rate in Iran, was US$ 1.93 billion. The most costly cancer for the males was stomach, while for the females it was breast cancer. The percentage of the total costs that were attributable to the top 10 cancers was 67% in the males and 71% in the females. Conclusions: The YPLL and productivity losses due to cancer-related premature mortality are substantial in Iran. Setting resource allocation priorities to cancers that occur in younger working-age individuals (such as brain and central nervous system) and/or cancers with high incidence and mortality rates (such as stomach and breast) could potentially decrease the productivity losses and the YPLL to a great extent in Iran.

Over a 3 year period, 10 premature infants with less than 37 weeks of gestational age underwent ductal ligation for patent ductus arteriosus. No patient died during operations which were done at a mean age of 30 days. One late death at 2 months after operation was not directly attributed to operative procedure. Follow-ups were done in 9 survived patients from 2 to 26 months. Results suggest that surgical ligation is a feasible and effective method for treating symptomatic premature infants with patent ductus arteriosus.

Advances in neonatal care system and research have resulted in an increased survival rate among low birth weight infants in the industrialized countries. Recent Korean neonatal mortality and morbidity statistics, and current status of Korean neonatal intensive care facilities were reviewed here for the sake of future improvement and research. Morbidity statistics revealed that perinatal diseases accounted for 80％ of the death of premature infants implying the possibility of its reduction by the vigorous prenatal care service in future.On the basis of extensive studies of nutritional support and growth rate of premature infants, commercial formulas for premature infants have been developed and various aspects of feeding techniques are standardized. However, problem of growth deficit of premature infants remains unsolved as medical problem. NICU specialists are challenged with the tasks of prenatal education or provision of care that minimizes the neurodevelopmental problems seen in preterm infants, various short-term outcome researches have been reported and those are reviewed here to promote research interest in the field of neonatal nursing. Systemic long-term outcome studies are also awaited in Korea for the formulation of welfare policy in future. Nursing science has to embrace all these interdisciplinary studies as their own research field in collaboration with neonatologist, nutritionist, rehabilitation therapist, social workers and teachers.
