RESUMEN

Background@#Although neuromyelitis optica spectrum disorder (NMOSD) is known to be a rare disease, its prevalence and incidence have not yet been studied in Korea. We performed a population-based study to examine the prevalence and incidence of NMOSD in Korea using data from the Korean National Health Insurance (NHI) claims database. @*Methods@#Data from 2013 to 2017 were obtained, with a washout period set as 2013 and 2014. The prevalence and incidence of NMOSD in 2016 and 2017 were calculated using population census data. Subjects were divided into 5 groups at 15-year intervals, depending on the age at which the diagnostic code was entered. The relative risk (RR) for each age group was compared with the oldest (≥ 60 years) age group. @*Results@#The overall prevalence was estimated to be 3.36 and 3.56 per 100,000 individuals, with an incidence of 0.41 and 0.65 per 100,000 individuals-year in 2016 and 2017, respectively. The mean age was 43.08 (standard deviation, 14.56) years, and the ratio of male to females was 1:4.7. The incidence was higher in female individuals aged between 30 and 59 years (RR, 2.8–3.05; P < 0.05). @*Conclusion@#Nationwide prevalence of NMOSD in Korea was 3.36 and 3.56/100,000 and its incidence was 0.41 and 0.65/100,000-year in 2016 and 2017 respectively.

RESUMEN

OBJECTIVE: To determine the prevalence of osteoporosis (OP) and osteoporotic vertebral fracture (OVF) in people with Parkinson’s disease (PD) in Korea and its association with socioeconomic status.METHODS: Using Health Insurance Review and Assessment Service-National Inpatient Sample (HIRA-NIS) data from 2009 to 2013, we estimated the annual prevalence of PD, OP, and OVF and investigated its association with socioeconomic status using data from National Health Insurance (NHI) beneficiaries and Medical Aid (MA) recipients. This study was supported by research funding from Korean Society for Bone and Mineral Research 2015. There were no study-specific biases related to conflicts of interest.RESULTS: The number of PD patients in the HIRA-NIS increased each year from 2009 to 2013. Among patients with PD, the standardized prevalence rates of OP and OVF increased from 2009 to 2013; from 23.2 to 27.8 and from 2.8 to 4.2, respectively. Among patients with PD with OP, the prevalence of OVF were 12.2% and 15.1% in 2009 and 2013, respectively. The standardized prevalence rates of PD with OP and PD with OVF were significantly higher in MA recipients than in NHI beneficiaries.CONCLUSION: The prevalence of PD both with OP and with OVF increased and the prevalence was higher in MA recipients than in NHI beneficiaries. These findings may suggest that age over 65 years, female and low income may be a significant factor related to PD occurring with OP and OVF.

RESUMEN

BACKGROUND: Pediatric palliative care (PPC) is the active total care of children suffering from life-threatening illnesses. Palliative care includes symptom management, psychosocial support, and end-of-life care. Despite significant advances in disease diagnosis and treatment, resources for PPC of children with serious illnesses are limited in Korea. This study aimed to investigate the scale, time trends, disease composition, regional distribution, and unmet needs of children dying from complex chronic conditions (CCCs). METHODS: We examined available information on children who died of CCCs from 2005 to 2014 using the cause of death statistics in Korea. RESULTS: There were 36,808 cases of pediatric deaths in Korea during that 10-year period, one-third (12,515 cases, 34.0%) of which were due to CCCs. In 2014, there were 1,044 cases of pediatric deaths due to CCCs (9.8 deaths per 100,000 children) in Korea. The rate of pediatric deaths due to CCCs has declined over this 10-year period. Among CCCs, malignancy was the most common cause of death overall, as well as in children and adolescents, whereas neonatal disorders were the most common cause of death in infants. Although over 1,000 children die from chronic illnesses each year, there are no hospitals or institutes in Korea that meet the minimum standards for specialized PPC. CONCLUSION: To improve the quality of life of children suffering from CCCs and to support their families who face enormous distress, children with CCCs should be able to access adequate palliative care services. Health authorities should consider supporting the establishment of PPC centers and increasing PPC accessibility in Korea.

RESUMEN

BACKGROUND AND PURPOSE: There have been a few national population-based epidemiological studies of myasthenia gravis (MG) with wide variation of incidence and prevalence rates worldwide. Herein we report the first nationwide population-based epidemiological study of MG in Korea. METHODS: We attempted to estimate the incidence and prevalence rates of MG using the Korean National Health Insurance claims database for 2010 to 2013. Cases with MG were defined as those having claim records with a principal diagnosis of MG and the prescription of acetylcholinesterase inhibitors or immunosuppressive agents including corticosteroids and azathioprine within 2 years after the diagnosis. The year 2010 was set as a washout period, such that patients were defined as incident cases if their first records of MG were observed in 2011. RESULTS: In 2011 there were 1,236 incident cases, and the standardized incidence rate was 2.44 per 100,000 person-years. The standardized prevalence rates were 9.67 and 10.66 per 100,000 persons in 2010 and 2011, respectively. The incidence and prevalence rates peaked in the elderly population aged 60 to 69 years for both sexes. CONCLUSIONS: This is one of the largest national population-based epidemiological studies of MG, and it has confirmed the high incidence and prevalence rates of MG in the elderly population of South Korea.

RESUMEN

The aim of this study was to investigate the whole picture regarding pregnancy, prenatal care, obstetrical complications, and delivery among disabled pregnant women in Korea. Using the data of National Health Insurance Corporation, we extracted the data of women who terminated pregnancy including delivery and abortion from January 1, 2010 to December 31, 2010. Pearson's chi-square test and Student-t test were conducted to examine the difference between disabled women and non-disabled women. Also, to define the factors affecting inadequate prenatal care, logistic regression was performed. The total number of pregnancy were 463,847; disabled women was 2,968 (0.6%) and 460,879 (99.4%) were by non-disabled women. Abortion rates (27.6%), Cesarean section rate (54.5%), and the rate of receiving inadequate prenatal care (17.0%), and the rate of being experienced at least one obstetrical complication (11.3%) among disabled women were higher than those among non-disabled women (P < 0.001). Beneficiaries of Medical Aid (OR, 2.21) (P < 0.001) and severe disabled women (OR, 1.46) (P = 0.002) were more likely to receive inadequate prenatal care. In conclusion, disabled women are more vulnerable in pregnancy, prenatal care and delivery. Therefore, the government and society should pay more attention to disabled pregnant women to ensure they have a safe pregnancy period up until the delivery.

RESUMEN

OBJECTIVES: Pregnant women in rural areas do not have access to sufficient obstetric services in their own communities due to the shortage of obstetricians. Therefore, most of these women must seek obstetrician outside of their communities. The purpose of this study was to investigate the relationship between obstetric complications and accessibility to local obstetric care in Korea. METHODS: This study was an ecological study in which the unit of analysis was an administrative district. Using Korea National Health Insurance Corporation data, the total number of deliveries and the delivery proportion within and outside of the community from 2001 to 2008 were calculated for 232 administrative districts nationwide. Three outflow levels were categorized based on each district's out-of-community delivery proportion: high outflow (upper one third), moderate outflow (middle one third), and low outflow (lower one third). In addition, three obstetric complication rates (the rate of complications following abortion, ectopic and molar pregnancy, the abortion rate, and the eclampsia rate) were calculated for the 232 districts. One-way ANOVA and multivariate linear regression were used to evaluate obstetric complications among the three outflow levels. RESULTS: The high outflow districts had higher rates of eclampsia and complications following abortion, ectopic, and molar pregnancy compared to the other districts (ANOVA, p<0.05). However, there was no significant difference in the abortion rate among the three groups. Multiple linear regression analysis showed that high outflow districts were statistically significant in the rate of complications following abortion, ectopic and molar pregnancy and eclampsia rate after adjusting for local tax per capita (p<0.01). CONCLUSION: These results indicate that poor access to local obstetric care correlate with poor obstetric outcomes (delayed or excessive bleeding, embolism, genital tract or pelvic infection, shock or other complications following abortion and ectopic or molar pregnancy, or eclampsia).

RESUMEN

BACKGROUNDS: To investigate the physical functioning state of the rural aged people and its related factors. METHODS: 458 older people aged 65 years or older living in a rural area were interviewed fromAug. 6 to Aug. 9, 2003. Socioeconomic characteristics, structural and functional social supports, chronic disease, stress, and obesity(using body mass index) were included to explore their influencing physical functioning. Physical functioning was measured by Physical Functioning(PF) scale constructed by 2-factor(mobility and self-care). Cronbach's alpha of social support and PF scales were 0.91, 0.89 respectively. After univariate analysis, multiple regression analysis was conducted to identify major contributing factors to physical functioning. RESULTS: 1) Person of younger age, higher education level, having job, higher economic status were more likely to show a higher degree of physical functioning in both male and female. 2) In those who having spouse, the physical functioning scores were significantly higher. And the aged people with high social support got higher physical functioning score. 3) In male with diabetes, physical functioning score were significantly lower. In female with arthritis, physical functioning score were significantly lower. 4) For the aged people which having higher stress, the physical function wasn't good. 5) In multiple regression analysis, for both male and female, physical functioning of those who have no job, lower social support, higher stress was bad. In male with chronic disease and female with arthritis, the physical functional score was lower. CONCLUSION: The physical functioning of some rural aged people were affected by various factors such as social, psychological, economic and physical factors. So diverse policy and programwill be necessary for improve physical functioning of rural older people.

RESUMEN

BACKGROUNDS: It is to find out ins and outs of falls, and then to study risky factors that are preventable. METHODS: Total 260 elderly people living in Nonsan who are 60 years old and over were analyzed for data. Stereotyped of those are populational, social specific, physical functions, and basis diseases. And concerning falls, it was analyzed if they have had experience of up to 5 times within 3 years recently. RESULTS: The analyzed are total 260 people, men 112(43%), and women 148(57%). And the ones who answered they have had experience of falls are 108(41.6%), men 31(28.7%), and women 77(71.3%), showing a distinguishable difference between two groups. Women have had more experience than men have(p<0.001), and according to their age, the average age of those experienced falls showed to be higher than the one of those who have not(p=0.036). And according to their education, the ones who did not go to any schools have had more experience than those who did, showing the education has something to do with falls(p<0.001). The mean mass index(p=0.043) and average weight(p=0.023) also showed a mere difference between the group of the people who have had experience and the one of those who have not. Taking into account the fact that there were more women in the group who have had experienced falls, it is shown that there is nothing practical to pay attention to. In Activity of Daily Living(ADL) the experienced is 10.8(+/-4.2), and the unexperienced 9.1(+/-3.1), showing a mere difference between two groups(p<0.000). Concerning chronic diseases, there was no difference between those two groups, but individual patient histories showed that the experienced group had less rheumatic trouble than the unexpedenced(p=0.033). Looking at the difference of the causes for the falls according to their gender, the range of their movements(p=0.043), illumination(p=0.012), influence of alcoho1(p=0.001), and the shoes when they were falling down(p<0.001), the first aid treatments after falls(p=0.014), and influence of medications(p<0.001) showed a mere difference between men and women, while did not show any difference in seasons, time of falls, places, and the descriptions of the surfaces of the places. The mean number of falls within recent 3 years of the experienced was 1.79 times, and the comparison of the relation between the frequency and the causes of falls was done between the ones with experience of I fall, and the ones with experience of more twice falls. The average height(p=0.046) was much higher thai those with experience of more than 2 falls. There was also a mere difference between two groups in movements(p=0.009), illumination(p=0.005), influence of alcohol(p=0.003), the shoes (p=0.048), and first aid treatments after falls(p<0.001). CONCLUSION: The group with higher risk rate includes women, age, poor education, skinny physical figures, and lack of ability to act in daily life. Therefore, those results should be considered when a preventive program of falls for elderly people is designed.

RESUMEN

The objectives of this study were to develop optimal analytic methods for detecting urinary 2-thiothiazolidine-4-carboxylic acid (TTCA) and thiocarbamide simultaneously and to evaluate the usefulness of these metabolites to a biological exposure index (BEI) for carbon disulfide (CS2) exposure. For this experiment, synthesized TTCA and thiocarbamide were used. The synthesized TTCA was identified by infrared spectrophotometer, nuclear magnetic resonance spectrometer and thin layer chromatography. The recovery rates of both metabolites were calculated to find the optimum analytical method. The amounts of urinary TTCA and thiocarbamide were measured by using an ultraviolet detector connected to high performance liquid chromatography (HPLC) after the administration of CS2 (350, 700 mg/kg) into Sprague-Dawley rats intraperitoneally. The maximum absorbance wave lengths for TTCA and thiocarbamide were 272 and 236 nm, respectively. Ethyl acetate extraction with NaCl as a salting-out reagent was used as a simultaneous extraction method for these metabolites. HPLC conditions for these metabolites included using a NH2 column, 50 mM KH2PO4: acetonitrile (85:15) and pH 3. Excreted amounts of urinary TTCA and thiocarbamide were increased significantly following CS2 administration. TTCA, which was already adopted as a BEI for CS2 by the American Conference of Governmental Industrial Hygienists (ACGIH), seems to be a more useful BEI for CS2 exposure than thiocarbamide. However further studies are needed to increase analytical efficiency before thiocarbamide can be adopted as a BEI and to apply this analytic method for simultaneous analysis of these metabolites in workers exposed to CS2.
