Objectives: The purpose of this study is to analyze agricultural accident and disease using statistical data and materials about National Survey for Health & Nutrition in 2001 and to provide fundamental materials for studies about farmers' health and safety, decision of priority about research and policy. Results: Diagnosed chronic disease prevalence is 72.4% in farmer/fisher group, 49.8% in non farmer/fisher group. The chronic disease prevalence of musculoskeletal disease, circulatory disease, and gastroenteric disease is 46.5%, 18.2%, and 17.9% in farmer/fisher group respectively. The prevalence of musculoskeletal disease in farmer/fisher is 2.4 times higher than non farmer/fisher. This result shows that it need to evaluation for risk factors of musculoskeletal disease preferentially. Lifetime accident/poisoning rate is 18.2% In farmer/fisher group and 13.3% in non farmer/fisher group. The types of accidents were fracture>sprain>contusion and the reasons of accidents were traffic accident>falling/sliding. Conclusions: "Bad or very bad" response of farmer/fisher is almost 2 times higher than non farmer/fisher group. The rate of smoking and no exercising in farmer/fisher group is higher than non farmer/fisher group.

Background : ATS(American Thoracic Society) defined new guidelines for COPD(chronic obstructive lung disease) in April 2001, following the results of the global initiative for chronic obstructive lung disease. The most important concept of COPD is an airflow limitation which is not fully reversible compared to bronchial asthma(BA). The criteria for COPD are postbronchodilator $FEV_1$ less than 80% of the predicted value and an $FEV_1$ per FVC ratio less than 70%. The global initiative for asthma(GINA) study defined asthma, which included immune-mediated chronic airway inflammatory airway disease, and found that airflow limitation was wide spread, variable and often completely reversible. Taken together COPD and BA may be combined in airflow limitation. This study was designed to evaluate the prevalence of BA in patients with COPD of moderate to severe airflow limitation. Methods : COPD was diagnosed by symptoms and spirometry according to ATS guidelines. Enrolled subjects were examined for peak flow meters(PFM), sputum eosinophils and eosinophil cationic protein(ECP) levels, serum total IgE with allergy skin prick test, and methacholine bronchial provocation test(MBPT). Results : About 27% of COPD patients with moderate to severe airflow limitation were combined with BA. There was significantly decreased response to PFM in severe COPD. However, there was no significant relationship between BA and COPD according to the degree of severity. The BA combined with COPD group showed significantly high eosinophil counts and ECP level in induced sputum. However, neutrophil counts in induced sputum showed significant elevation in the pure COPD group. Conclusion : Twenty-seven percent of COPD patients with moderate to severe ventilation disorder were combined with BA, but there were no significant differences according to the degree of severity.
Objectives: Insomnia is not only the most common sleep-related disorder, but also is one of the most important. Knowledge of the comorbidities of insomnia is essential for proper treatment including pharmacological and non-pharmacological methods to prevent disease chronification. This study aimed to determine sleep clinic patients' knowledge of insomnia. Methods: This study recruited 44 patients (24 males and 20 females; mean age $54.11{\pm}16.30years$) from the sleep clinic at National Center for Mental Health. All subjects were asked to complete a self-report questionnaire about their reasons for visiting a sleep clinic and about their knowledge of treatment and comorbidities of insomnia. Results: The reasons for visiting the sleep clinic were insomnia symptoms of daytime sleepiness, irregular sleeping time, nightmares, snoring, and sleep apnea, in that order. Of the responders, 72.7% had a comorbidity of insomnia, and 22.7% showed high-risk alcohol use. In addition, 70.5% of responders chose pharmacological treatment of insomnia as the first option and reported collection of information about treatment of insomnia mainly from the internet and medical staff. More than half (52.3%) of the respondents reported that they had never heard about non-pharmacological treatments of insomnia such as cognitive behavioral treatment (CBT-I) or light therapy. The response rate about comorbidities of varied, with 75% of responders reporting knowledge of the relation between insomnia and depression, but only 38.6% stating awareness of the relation between insomnia and alcohol use disorder. Of the total responders, 68.2% were worried about hypnotics for insomnia treatment, and 70% were concerned about drug dependence. Conclusion: This study showed that patients at a sleep clinic had limited knowledge about insomnia. It is necessary to develop standardized insomnia treatment guidelines and educational handbooks for those suffering from insomnia. In addition, evaluation of alcohol use disorders is essential in the initial assessment of sleep disorders.

Objectives : A growing body of evidence links type 2 diabetes (T2D) with a neurodegenerative disease (ND) such as Alzheimer's disease and Parkinson's disease. The purpose of this study is to investigate the relationship between NDs and the development of T2D by comparing the incidence of T2D in a group of various NDs (ND group) and control group. Methods : A population-based 10-year follow-up study was conducted using the Korean National Health Information Database for 2002-2015. We used a retrospective cohort study design to investigate the association of ND with T2D occurrence. The study population included ND (n=8,814) and control (n=37,970) groups, all aged 60 years or over. The Kaplan-Meier method was used to estimate the risk of developing T2D as a function of time. Cox proportional hazards regression models were used to evaluate the relationship between ND and T2D. Results : T2D was developed in a significantly higher percentage of patients in the ND group (53.6%) than in the control group (44.7%). The ND group increased the risk of T2D (HR, 1.43; 95% CI, 1.38-1.47). About one-third of patients in both groups were additionally diagnosed with another ND before the occurrence of T2D during a 10-year follow-up period. When compared to those who did not have another ND during the follow-up period, the incidence of T2D in those who were additionally diagnosed with another ND was higher in both the ND and control groups. Conclusions : The ND group had about 1.4 times higher risk of developing T2D than the control group. Our results showed a positive association between ND and T2D.
Liver transplantation is definitive treatment for the patients suffering from hepatitis, severe liver cirrhosis and liver cancer. In these patients, systemic infections under immunosuppression may occur easily. Therefore, primary object of dental treatments before liver transplantation is absolute removal of oral infection source. In addition, comprehensive dental management plan is essential for success of liver transplantation. The present study has been performed to investigate decayed, missing and filled permanent teeth index(DMFT index), degree of oral hygiene, past medical history, need of dental treatment, completion of dental treatment need and time interval between dental visit and operation date of liver transplantation in liver transplant candidates. Obtained results were as follows; 1. Decayed teeth of the patients were 2.68, missing teeth were 4.02 and filled teeth were 3.42. DMFT index was 10.12. 2. Twenty percents of patients showed moderate to severe food impactions, 42.2% of patients had moderate to heavy calculus and 37.8% of patients displayed gingival inflammation with swelling. 3. Patients needed periodontal treatments more than any other dental treatments. Periodontal treatments were needed for 88.9% of patients, operative & endodontic treatments were 46.7% of patients and 33.3% of patients needed for oral & maxillofacial surgical treatments. 4. Among 90 patients, time interval between scheduled operation date of liver transplantation and dental visit was within 2 weeks for 32.2% of patients, within 1 week for 20.0% of patients. In conclusion, most liver transplant candidates needed dental treatments for removal of potential infection sources. However because of insufficient interval between dental visit and operation date, they had taken liver transplantation procedures without comprehensive dental management. Development of preventive and comprehensive dental management program is mandatory for these patients. Cooperative interdisciplinary management will play a positive role for successful liver transplantation.
As a test for diagnosing fatty liver, recently, ultrasound and blood exam are being performed simultaneously. In particular, in the case of high-sensitivity C-reactive protein in blood exam, it is used as an index indicating the level of inflammation in various parts of the body as well as cardiovascular diseases. Thus, this study was conducted to analyze the association between metabolic syndrome components, liver function, and high-sensitivity C-reactive protein levels according to the degree of nonalcoholic fatty liver, and use it as a clinical indicator for fatty liver diagnosis. Metabolic syndrome components, liver function and high-sensitivity C-reactive protein blood test values analyzed from 1,139 men and women over 20 years of age with nonalcoholic fatty liver in abdominal ultrasonography from March 2021 to August 2021 at the Korea Association of Health Promotion, Gwangju-Jeonnam Branch. Analyzed for all men and women, the blood test values for subjects with mild fatty liver were AST 30 U/L, ALT 32.1 U/L, γ-GTP 41.2 IU/L, and hs-CRP 0.14 mg/dL. These values were lower than the blood test values of subjects with moderate fatty liver (AST 38 U/L, ALT 47.6 U/L, γ-GTP 54.9 IU/L, hs-CRP 0.22 mg/dL) and was statistically significant (p<0.001). In this case of high-sensitivity C-reactive protein test, it is statistically significant, showing higher values in Subjects with moderate fatty liver than Subjects with mild fatty liver. thus, it is considered that hs-CRP can be used as clinical data for the prevention and management of fatty liver.
Asbestos has been actively used for various places. Since it was designated as the first grade carcinogen in the 1970s, strict regulations on using asbestos has been implemented globally. Considering long-term latent periods between asbestos exposure and environmental diseases, we analyze the time lag between asbestos consumption and the incidence of mesothelioma in Korea and estimate the long-run relationship. In addition, we conduct a comparative analysis on the effectiveness of asbestos regulations in the United Kingdom and the United States, which have accumulated long-term time-series observations. The latent period analysis indicates that the consumption of asbestos and the incidence of the disease are highly correlated in all three countries, being long-term lags of more than 30 years. Also, we find a long-run equilibrium relationship between asbestos consumption and the incidence of mesothelioma in the presence of long-term lags between the variables in all three countries. Furthermore, using a distributed lag model, asbestos consumption has statistically significant positive effects on mesothelioma with a long-term lag.

Purpose: Physical activity (PA) has a beneficial effect on the prevention of arteriosclerosis in healthy adults. The purpose of this study was to analyze the relationship between PA measured using an accelerometer and arterial stiffness in healthy Korean adults. Methods: This study involved 87 subjects (36.8% women) aged 20-64 years. PA was evaluated using an accelerometer (wGT3X-BT, ActiGraph, Florida, USA) for 7 days. Based on the results of the accelerometer measurement, subjects were classified into active and inactive groups according to the World Health Organization (WHO) PA guidelines. The brachial-ankle pulse wave velocity (baPWV) and ankle-brachial index (ABI) to assess arterial stiffness were measured by a non-invasive vascular screening device (VP-1000 Plus, Omron). Results: The average age of the study subjects was 47.7 ± 11.3 years and the WHO PA guideline achievement rate was 29.9%. There was no significant difference in arterial stiffness (baPWV and ABI) between the active and inactive groups. In females, the time spent in light PA were positively correlated with ABI (r = 0.396; p < 0.05) and the number of sedentary bouts over 50 minutes was inversely correlated with ABI (r = -0.402; p < 0.05). However, there was no significant correlation between PA and arterial stiffness in males. Conclusions: The results of this study suggest that light PA and sedentary behavior have a positive correlation with arterial stiffness in females.
Purpose : IgA nephropathy (IgAN) is the most commonly occurring form of chronic glomerulonephritis in pediatric cases. Human leukocyte antigen (HLA) genes have been implicated in various inflammatory and autoimmune diseases. The present study was conducted to investigate the association between 2 single nucleotide polymorphisms (SNPs) of the HLA-G gene and childhood IgAN. Methods : The authors analyzed and compared $HLA-G$ gene SNPs (rs1736936 and rs2735022) in 174 patients with childhood IgAN and in 438 healthy controls. In addition, IgAN patients were dichotomized and compared with respect to proteinuria (< and >$4mg/m^2/hour$), the presence or absence of podocyte foot process effacement, and the presence of pathologically early and advanced disease markers such as interstitial fibrosis, tubular atrophy, or global sclerosis. Results : No significant SNP frequency differences were observed for the $HLA-G$ gene between IgAN patients and the control group. Moreover, no significantly associated SNP was observed with the presence of proteinuria, podocyte foot process effacement, or pathologically advanced markers. However, the haplotype, composed of rs1736936 and rs2735022, showed a significant association with the susceptibility to develop childhood IgAN (haplotype T/C: dominant model, $P$=0.049; haplotype C/T: recessive model, $P$=0.030). Conclusion : Our results indicate that rs1736936 and rs2735022 as the $HLA-G$ gene promoter haplotype might be associated with the susceptibility to develop childhood IgAN in the Korean population.
Hepatomegaly and liver dysfunction might develop in patients with diabetes mellitus due to glycogen deposition or nonalcoholic steatohepatitis. We experienced a case of hepatic glycogenosis in a patient with type 1 diabetes mellitus who presented with recurrent hypoglycemia, suggesting impairment of glycogenolysis and gluconeogenesis. A 10-year-old girl with a 4-year history of type 1 diabetes mellitus was admitted because of recurrent hypoglycemia and abdominal pain in the right upper quadrant. She had Cushingoid features and hepatomegaly that extended 6 cm below the right costal margin. Laboratory data and radiologic examination revealed elevated liver enzyme levels due to fatty liver. Periodic acid-Schiff (PAS) staining revealed intense glycogen deposition in the cytoplasm of the hepatocytes and PAS reactivity was lost with diastase treatment. At 2 months after administration of glucagon injection and uncooked cornstarch between meals and at bedtime, the hypoglycemic episodes and liver dysfunction improved. It is important to distinguish hepatic glycogenosis from steatohepatitis, because it is possible to prevent excessive hepatic glycogen storage in hepatic glycogenosis cases by strictly controlling blood glucose level and by glucagon administration. To prevent severe hypoglycemic symptoms accompanied by hepatic glycogenosis, we suggest that uncooked cornstarch, which is effective in maintaining blood glucose level, can also be administered.
