ABSTRACT

Objective@#There are animal models associating dopamine dysfunction with behavioral impairments that model attention deficit hyperactivity disorder (ADHD). Erythropoietin (EPO) has trophic effects on dopaminergic neurons. The aim of this study was to examine the EPO plasma levels and determine whether there was any correlation between plasma EPO levels and clinical characteristics of ADHD. @*Methods@#Plasma EPO levels were measured in 78 drug-naïve children with ADHD and in 81 healthy children. The severity of ADHD symptoms was determined by scores on the Korean ADHD Rating Scale (K-ARS) in ADHD children and healthy controls. @*Results@#The difference between median plasma EPO levels in ADHD children and in healthy controls was not statistically significant. Adjusting for age and sex, a linear regression analysis showed that inattention score was significantly higher in the second highest tertile of plasma EPO compared to those in the lowest tertile. Hyperactivity-impulsivity score was significantly higher in the highest tertile of plasma EPO compared to those in the lowest tertile. Moreover, total K-ARS scores were significantly higher in the second highest tertile of plasma EPO compared to those in the lowest tertile. @*Conclusion@#These findings suggest that plasma EPO levels were related to some ADHD symptoms, which could be used in the monitoring of the disorder.

ABSTRACT

Objectives@#This study investigated the effects of comorbid sleep disorders (SD) on the incidence of cardiovascular complications among newly-diagnosed hypertension (HTN) patients. @*Methods@#As study population, 124 057 newly-diagnosed essential HTN patients aged 30 or older, without cardiovascular complications at diagnosis with HTN, were selected from the National Health Insurance Service-National Sample Cohort. The incidence of cardiovascular complications was calculated, Cox proportional-hazards regression model was used to analyze the risk of complications, and the population attributable fraction (PAF) for cardiovascular complications of having comorbid SD at HTN diagnosis was calculated. @*Results@#Over 10 years, 32 275 patients (26.0%) developed cardiovascular complications. In HTN patients with comorbid SD at diagnosis of HTN, the incidence of cardiovascular complications (78.3/1000 person-years; 95% confidence interval [CI], 75.8 to 80.9) was higher than in those without comorbid SD (58.6/1000 person-years; 95% CI, 57.9 to 59.3) and the risk of cardiovascular complications was 1.21 times higher (95% CI, 1.17 to 1.25), adjusting for age, gender, income, area of residence, and comorbid diabetes mellitus. The PAF of having comorbid SD at diagnosis of HTN for the incidence of cardiovascular complications was 2.07% (95% CI, 1.69 to 2.44). @*Conclusions@#Newly-diagnosed essential HTN patients aged 30 or older who had comorbid SD at the time of their HTN diagnosis had a higher incidence of cardiovascular complications than those without comorbid SD. Age, gender, income, area of residence, and comorbid diabetes mellitus had a significant effect on the incidence of cardiovascular complications. Approximately 2% of cardiovascular complications were found to occur due to the presence of SD.

ABSTRACT

Background@#and PurposeThis study was designed to investigate differences in the final recommended pressure setting between that derived from an autotitrating continuous positive airway pressure (APAP) device and manual in-laboratory continuous positive airway pressure (CPAP) titration, as well as the factors that influence pressure differences in patients with obstructive sleep apnea (OSA). @*Methods@#This study enrolled 50 patients with OSA. All patients underwent both APAP titration and manual CPAP titration. We obtained the average device pressure ≤90% of the time (APAP90) from the downloaded manual for the APAP machine and the optimal pressure obtained by manual CPAP titration (CPAPmanual). We placed the subjects into three groups based on the pressure difference (ΔP) obtained by subtracting CPAPmanual from APAP90: 1) Prequal (ΔP=0), 2) CPAPmanual+ (ΔP ≤−1), and 3) APAP90+ (ΔP ≥1). Regression analysis was conducted to identify predictive factors associated with ΔP. @*Results@#The values of APAP90 and CPAPmanual were 9.50±3.03 cmH2O and 9.48±2.71 cmH2O (mean±SD), respectively (p=0.95). The Prequal, CPAPmanual+, and APAP90+ groups comprised 9 (18%), 23 (46%), and 18 (36%) subjects, respectively. Regression analyses revealed that male sex [β=3.539, 95% confidence interval (CI)=0.040–7.039], body mass index (BMI) (β=0.186, 95% CI=0.020–0.352), and average usage per day (β=0.768, 95% CI=0.077–1.459) were associated with ΔP. @*Conclusions@#While the mean pressure in the overall cohort did not differ significantly between APAP90 and CPAPmanual, there was a discordance majority showing different single pressures obtained when applying the two titration methods. Being Male, having an increased BMI, and having an increased average usage per day of APAP were significantly correlated with increased ΔP in this study.

ABSTRACT

Background@#In Korea, the Korean Community-based Noncommunicable Disease Prevention and Control Program (KCNPC) was implemented in 2012 for the management of patients with chronic diseases. Nineteen primary care clinics, public health centers, and education and consulting centers (ECCs) participated in the implementation of this program. This study assessed the effectiveness of this chronic disease control model by comparing mortality rate and the incidence of complications between patients participating in the KCNPC program and a control group. @*Methods@#Using data from the National Health Insurance Service and data from hypertension and diabetes patients registered with 19 ECCs between January 1, 2010 and December 31, 2012, hypertension and diabetes patients who had been treated at a clinic were selected. The final analysis included 252,900 patients, with the intervention group and control group having 126,450 patients each. Survival for the two groups was analyzed using the Kaplan-Meier method. Complications were analyzed using the Cox proportional hazards model. @*Results@#The 5-year survival rate in the intervention group (0.88) was higher than that in the control group (0.86). Cox proportional hazards analysis showed that the intervention group had lower risk for mortality (0.84; 95% confidence interval [CI], 0.82–0.86) compared to the control group. Hospitalization due to complications and the proportional risk of hospitalization were also lower in the intervention group. @*Conclusion@#The KCNPC model for prevention and control of chronic disease in Korea was found to be effective for hypertension and diabetes patients. Therefore, the KCNPC will be necessary to strengthen the capabilities of local communities, primary medical institutions, and individuals for prevention and control of chronic disease. Expanding the efficient prevention and control policies of the KCNPC to a nationwide scale may be effective as has been demonstrated through limited implementation in some regions.

ABSTRACT

BACKGROUND AND OBJECTIVES: This study aims to evaluate the usefulness of customized vestibular exercise through literature review. MATERIALS AND METHOD: We searched several literature database such as Ovid-MEDLINE, Ovid-EMBASE, and Cochrane Library etc., with the following inclusion criteria: 1) studies of patients with dizziness and balance disorders, 2) studies in which a customized vestibular exercise was performed, and 3) studies in which one or more of the appropriate medical outcomes have been reported. At the same time, we excluded the following: 1) non-human studies and pre-clinical studies, 2) non-original articles, for example, non-systematic reviews, editorial, letter and opinion pieces, 3) research not published in Korean and English, 4) grey literature (thesis, congress or conference materials, abstract etc.), and 5) case studies. Finally, 10 studies were selected and analyzed. RESULTS: The safety of customized vestibular exercise was reported in three documents which reported no side effects related to the procedure. The effectiveness of customized vestibular exercise was proven by the assessment of symptom change, functional change, and other physiological measures based on a total of 10 randomized clinical trial studies. CONCLUSION: For patients with vestibular dysfunction, a customized vestibular exercise can be a safe and effective technique for improving dizziness and balance function.

ABSTRACT

PURPOSE: Anaphylaxis is an acute, life-threatening systemic reaction which should be treated by epinephrine, and patients should be prescribed epinephrine auto-injector after the event. The purpose of this study was to investigate the clinical features of pediatric anaphylaxis, including the rate of using epinephrine at hospital and prescribing epinephrine auto-injector. METHODS: We performed a retrospective study of 68 anaphylactic patients at in-hospital, out-hospital, and Emergency Department of Soonchunhyang University Cheonan Hospital, Cheonan, Korea, who were under 15 years of age, from January 2013 through December 2014. We reviewed their clinical features, doctor's treatment methods, rate of follow-up and prescribing epinephrine auto-injectors. RESULTS: Causes of anaphylaxis were food (76.5%), drug (10.3%), and idiopathic (13.2%). The involved organs were the skin (86.8%), respiratory tract (80.9%), cardiovascular system (23.5%), and gastrointestinal tract (17.7%). Patients were treated with systemic steroids (91.2%), antihistamines (88.2%), and epinephrine (75.0%). Fifty-three patients (77.9%) revisited our pediatric allergy clinic and epinephrine auto-injectors were prescribed for 25 patients (36.8%). CONCLUSION: Physicians should make an effort to use epinephrine as an initial treatment of anaphylaxis, to prescribe epinephrine auto-injectors, and to give proper information about disease.

ABSTRACT

BACKGROUND AND PURPOSE: There has been no nationwide population-based study of the prevalence of self-perceived snoring/apnea in Korean adolescents. The purpose of this study was to estimate prevalence of self-perceived snoring/apnea in Korean high-school students and to evaluate their association with daytime sleepiness. METHODS: An online survey was used to investigate 12,672 students at 75 high schools across the 15 nationwide districts of South Korea. The variables were obtained using a self-reported questionnaire. The students answered questions about self-perceived snoring/apnea during the past 30 days. Daytime sleepiness was measured using a validated Korean version of the Epworth Sleepiness Scale, which was modified for adolescents. Covariates were the sex, school grade, frequency of self-perceived snoring/apnea, body mass index, sleep duration during a school day, and subjective perception of sleep duration. RESULTS: The prevalence of self-perceived snoring/apnea was 22.8% (26.4% for males vs. 18.8% for females, p<0.001) and 9.2% (10.5% for males vs. 7.7% for females, p<0.001). Obesity was significantly associated with self-perceived snoring [odds ratio (OR)=2.18, 95% confidence interval (CI)=1.94–2.46] and apnea (OR=1.57, 95% CI=1.33–1.86). Multivariate analysis showed that any frequency of self-perceived snoring/apnea was significantly associated with excessive daytime sleepiness (EDS). The OR of EDS increased significantly with the frequency of snoring and apnea. Female, sleep duration of <5 hours during a school day, and subjective perceptions of insufficient and considerable sleep durations were also significantly associated with EDS. CONCLUSIONS: The prevalence of self-perceived snoring/apnea was significantly higher in students who were male and obese. Students with self-perceived snoring/apnea exhibited more significant EDS and an increased risk of EDS as the frequency of snoring and apnea increased.

ABSTRACT

BACKGROUND/AIMS: To investigate the effects of esomeprazole and rebamipide combination therapy on symptomatic improvement in patients with reflux esophagitis. METHODS: A total of 501 patients with reflux esophagitis were randomized into one of the following two treatment regimens: 40 mg esomeprazole plus 300 mg rebamipide daily (combination therapy group) or 40 mg esomeprazole daily (monotherapy group). We used a symptom questionnaire that evaluated heartburn, acid regurgitation, and four upper gastrointestinal symptoms. The primary efficacy end point was the mean decrease in the total symptom score. RESULTS: The mean decreases in the total symptom score at 4 weeks were estimated to be −18.1±13.8 in the combination therapy group and −15.1±11.9 in the monotherapy group (p=0.011). Changes in reflux symptoms from baseline after 4 weeks of treatment were −8.4±6.6 in the combination therapy group and −6.8±5.9 in the monotherapy group (p=0.009). CONCLUSIONS: Over a 4-week treatment course, esomeprazole and rebamipide combination therapy was more effective in decreasing the symptoms of reflux esophagitis than esomeprazole monotherapy.

ABSTRACT

BACKGROUND AND PURPOSE: Sleep need differs between individuals, and so the same duration of sleep will lead to sleep insufficiency in some individuals but not others. The aim of this study was to determine the separate and combined associations of both sleep duration and unmet sleep need with excessive daytime sleepiness (EDS) in Korean adults. METHODS: The participants comprised 2,769 Korean adults aged 19 years or older. They completed questionnaires about their sleep habits over the previous month. The question regarding sleep need was "How much sleep do you need to be at your best during the day?" Unmet sleep need was calculated as sleep need minus habitual sleep duration. Participants with a score of >10 on the Epworth Sleepiness Scale were considered to have EDS. RESULTS: The overall prevalence of EDS was 11.9%. Approximately one-third of the participants (31.9%) reported not getting at least 7 hours of sleep. An unmet sleep need of >0 hours was present in 30.2% of the participants. An adjusted multivariate logistic regression analysis revealed a significant excess risk of EDS in the groups with unmet sleep needs of ≥2 hours [odds ratio (OR), 1.80; 95% confidence interval (CI), 1.27-2.54] and 0.01-2 hours (OR, 1.42; 95% CI, 1.02-1.98). However, habitual sleep duration was not significantly related to EDS. CONCLUSIONS: EDS was found to be associated with unmet sleep need but not with habitual sleep duration when both factors were examined together. We suggest that individual unmet sleep need is more important than habitual sleep duration in terms of the relation to EDS.

ABSTRACT

BACKGROUND: The present study investigated the prevalence of depressive symptoms in older Koreans and identified associations between depressive symptoms and occupational factors. METHODS: Data from the Korean National Health and Nutrition Examination Survey V (2010–2012) were used to analyze 7320 participants aged 55 years or older. Complex sample logistic regression analysis was performed after adjusting general characteristics to determine associations between depressive symptoms and occupational factors. RESULTS: Among older Korean men, the prevalence of depressive symptoms in the employed and the non-employed groups were 9.9 % and 13.7 %, respectively. Employment status was significantly associated with depressive symptoms after adjusting for general factors (OR: 0.69, 95 % CI: 0.49–0.97). Among older Korean women, the prevalence of depressive symptoms in the employed and the non-employed groups were 17.4 % and 20.3 %, respectively, but employment status was not significantly associated with depressive symptoms. Second skill level occupational groups (clerks, plant and machine operators) in particular showed significantly lower prevalence of depressive symptoms than the non-employed group of men (9.3 % vs 13.7 %). By occupation type, the odds ratios were 0.31 (95 % CI: 0.10–0.97, clerks) and 0.47 (95 % CI: 0.23–0.86, plant and machine operators) adjusting for general factors. CONCLUSIONS: The employed group showed lower late-life depressive symptom prevalence than the non-employed group among older Korean men. In addition some second skill level occupations (clerks, plant and machine operators) were significantly associated with a lower risk of depressive symptoms after adjusting for general factors in older Korean men.

ABSTRACT

OBJECTIVE: Onion and garlic are a commonly consumed food in the Korean population. But these food materials have rarely been studied for their allergenic potentials. We analyzed the sensitization rate of garlic and onion using multiple allergen simultaneous test (MAST)-immunoblot assay. METHODS: From January 2009 to December 2013, we analyzed the results of the MAST immunoblot assay performed in 2,691 allergy patients at Soonchunhyang University Cheonan Hospital, retrospectively. RESULTS: Among 2,691 patients, 1,063 were under 18 years old, and 1,628 were over 18 years old. In the all age groups, 29 patients (1.08%) were positive to garlic, 54 patients (2.01%) were positive to onion and one patient was positive to garlic and onion and others. A total of 84 patients (3.12%) were positive to garlic or onions. In infants under the age of 2 years, garlic was the seventh and onion was the nineteenth common food allergen, and onion was more common than rice. While getting older, the sensitization rate of garlic decreased (P<0.001), but onion increased (P<0.01). CONCLUSION: Using one of the semi-quantitative methods, MAST immunoblot assay, we realized that the sensitization rate of garlic was higher than rice or wheat in infants. We presume further studies on the role of garlic and onion in food allergy are needed.

ABSTRACT

OBJECTIVES: We examined the trends in prevalence, awareness, treatment, and control of hypertension in Korea as a basis for improving hypertension control programs. METHODS: 12 598 participants of the Korean National Health and Nutrition Examination Survey were included in this study. Weighted linear regression to test time trends from 2007 to 2011 was performed. RESULTS: The prevalence of hypertension was 20.7% in 2007, 29.4% in 2009, and 26.2% in 2011. Awareness of hypertension was 64.8% in 2007 and 61.1% in 2011. Awareness in those aged 65 and over was greater than in younger groups (age 19 to 44 and 45 to 64; p<0.001). The treatment rates were 58.4% in 2007 and 56.8% in 2011. The treatment rate was greater for those 65 and over than for younger age groups (p<0.001). The percentage of controlled hypertension was 37.6% in 2011. The percentage of controlled hypertension in those 65 and over was higher than in younger age groups (p<0.001). The treatment-control rates were 65.9% in 2007 and 67.7% in 2011. The prevalence of hypertension was higher in the males (p<0.001), while the awareness (p<0.001), treatment (p<0.001), and control (p<0.001) rates were higher in the females. CONCLUSIONS: The prevalence of hypertension was increasing and the hypertension awareness, treatment, and control rates were low in younger age groups and males.

ABSTRACT

Recently, Sejong City had been in the center of a policy dispute about city planning in Korea. Although Sejong City was chosen to be a new Multifunctional Administrative City in 2006, politicians continued to challenge the decision at the city level from 2009 upto 2010.This study aims to investigate what influences, such as the policy dispute, impacted the health behaviors and the mental health of local people. We used the survey data from the Community Health Survey in 2008, 2009, 2010, and 2011 and compared the results through logistic regression analysis and direct standardization. Data were gathered from residents in Chungcheongnam-do, the province where Sejong City is located. Data from residents of four other provinces were used as a control: Gangwon-do, Gyeongsangbuk-do, Jeonlanam-do, and Gyeonggi-do. We found a significant increase in smoking and drinking rates in the residents of Chungcheongnam-do, which are indicators of health behaviors, in the year of 2009 when the Sejong City dispute erupted. It appears that controversial changes in government policy could have negative influences on local people. Therefore, we need proper measures to prevent them.

ABSTRACT

BACKGROUND/AIMS: The most important adverse effect of azathioprine (AZA) is bone marrow toxicity (BMT). Many physicians have preferred a gradual dose increment (GDI) policy for the prevention of BMT. The aim of this study was to evaluate the efficacy of GDI for the prevention of AZA-induced BMT in inflammatory bowel disease (IBD) patients. METHODS: The medical records of IBD patients who received AZA in 6 university hospitals were reviewed. The patients were divided into two groups: the GDI group (initial dose or =2 mg/kg). RESULTS: A total of 308 patients were enrolled (male to female ratio, 1:2.3; mean age, 34.91+/-14.19 years; ulcerative colitis, 43.5%; Crohn's disease, 55.2%; and intermediate colitis, 1.3%). The overall incidence of BMT was 16.2% (50/308). BMT developed most frequently between fourth to eighth week (26%, 13/50). The rate of BMT of the non-GDI group was significantly higher than that of the GDI group (27.5%, 11/40 vs. 14.6%, 39/268, P=0.038). A multivariate analysis showed that the only factor related to BMT was a non-GDI policy (P=0.036; odds ratio, 2.41; 95% confidence interval, 1.06-5.49). CONCLUSIONS: A GDI policy could be useful for reducing AZA-induced BMT in Korean IBD patients.

ABSTRACT

OBJECTIVE: A number of studies have reported association between Toxoplasma gondii (T. gondii) and Chlamydia infection and the risk of schizophrenia. The aim of the present study was to compare the prevalence of T. gondii and Chlamydia infection between the schizophrenia and normal control subjects and to compare the clinical features between seropositive and seronegative schizophrenia patients. METHODS: The rate of serum reactivity to T. gondii, Chlamydia trachomatis (C. trachomatis), Chlamydia pneumonia in 96 schizophrenia and 50 control subjects was investigated using enzyme-linked immunosorbent assay and indirect fluorescent antibody technique. The clinical symptoms of the schizophrenia patients were scored with Positive and Negative Syndrome Scale and a comparative analysis was carried out. RESULTS: A significant positive association between immunoglobulin G (IgG) antibodies to T. gondii and C. trachomatis in schizophrenia was found, and the odds ratio of schizophrenia associated with IgG antibody was found to be 3.22 and 2.86, respectively. The Toxoplasma-seropositive schizophrenia patient had higher score on the negative subscale N1 and N7 and general psychopathology subscale G13, while C. trachomatis-seropositive schizophrenia patient had higher score on the general psychopathology subscale G10. CONCLUSION: The results from the present study suggest significant association between T. gondii, C. trachomatis infection and schizophrenia. In future, further studies are needed to elucidate the correlation between the two types of infection and schizophrenia.

ABSTRACT

OBJECTIVE: The study aimed to determine which factors influence the occurrence of cardio-cerebrovascular diseases. The researchers analyzed differences in health behaviors and social strata according to each type of cardio-cerebrovascular disease, examined regional characteristics and compared the study's results with the past research data. METHODS: In statistical analysis, multiple logistic regression was conducted by utilizing the raw data obtained from the 2010 Chungcheongnam-do Community Health Survey. RESULTS: The results showed that cardio-cerebrovascular diseases were influenced by alcohol consumption, obesity and monthly income.

ABSTRACT

The etiology of Crohn's disease, which is a chronic inflammatory condition that potentially involves any location of the alimentary tract from the mouth to the anus, is unknown. However, there is strong evidence that vascular damage could play a role in the pathogenesis of Crohn's disease. Crohn's disease is mediated by multifocal gastrointestinal infarctions, which occur at an early stage in the disease process. Persistent activation of coagulation in patients with Crohn's disease has been shown. In contrast, hemophilia is an inherited disorder of coagulation. The deficiencies of clotting factors usually involve occult or overt bleeding. The pathogenic mechanisms of Crohn's disease and hemophilia are incompatible. An association between Crohn's disease and hemophilia has not been reported in Korea. We managed 21- and 33-year-old men with Crohn's disease associated with hemophilia, who presented with hematochezia.
