Abstract Dermatophytosis includes all fungal infections caused by dermatophytes in humans. Some risk factors for the development of subtypes of dermatophytosis have been studied; however, large-scale epidemiologic studies on risk factors for total dermatophytosis are scarce. We investigated the risk factors of dermatophytosis using a nationwide study. Total 4,532,655 subjects with dermatophytosis aged between 20 to 40 years were examined using data from the Korean National Health Insurance Service from 2009 to 2018. Women showed a lower risk of development of dermatophytosis compared to men (hazard ratio [HR], 0.848; 95% confidence interval [CI], 0.843–0.853). Subjects with elevated waist circumference (HR, 1.057; 95% CI, 1.048–1.065), heavy drinking (HR, 1.053; 95% CI, 1044–1.061), engaging in mild-to-heavy exercise (HR, 1.071; 95% CI, 1.064–1.077) had a higher risk of dermatophytosis. In addition, subjects with body mass index (BMI) of more than 30 kg/m2 exhibited a higher risk of dermatophytosis (HR, 1.36; 95% CI, 1.342–1.378) compared to those with BMIs in the range of 18.5 to 23 kg/m2. In this study, the risk of developing dermatophytosis significantly increased in individuals with elevated waist circumference or high BMI. Lifestyle modifications, including weight management, are suggested to be important in preventing dermatophytosis.

AbstractKey PointsQuestionWhat is the relationship between the previously known risk factors and occurrence of carpal tunnel syndrome (CTS)?FindingsIn this retrospective population-based cohort study that included 512,942 participants sampled from the Korean National Health Insurance System database, we determined the following known risk factors were related to the occurrence of CTS: the age of 40s, female, being overweight, diabetes, rheumatoid arthritis, gout, and Raynaud’s syndrome. However, ESRD, hypothyroidism and smoking were not correlated with CTS occurrence.ImplicationsWe identified the age of 40s, female, overweight, diabetes, rheumatoid arthritis, gout, and Raynaud’s syndrome as risk factors for the occurrence of CTS.AbstractImportanceThere have been few large-scale studies that have included a risk factor analysis for CTS. No prior study has investigated and validated the relationship between the occurrence of CTS and known risk factors using nationwide health care database.ObjectiveTo confirm the actual risk factors for CTS out of various known risk factorsDesignWe conducted this study using a retrospective cohort model based on the combined two databases of the Korean National Health Insurance System; the national periodic health screening program database from 2002–2003 and health insurance database of reimbursement claims from 2003 through 2013.SettingA population-based retrospective cohort study.ParticipantsFirst, we randomly sampled 514,795 patients who represented 10% of the 5,147,950 people who took part in periodic health screenings in 2002–2003. Existing CTS patients were excluded from this group. Therefore, this study finally included 512,942 participants and followed up their medical records from 2003–2013.Main Outcomes and MeasuresDesired outcomes were the incidence rate of CTS in patients with various risk factors and the hazard ratios of risk factors affecting the disease’s occurrence.ResultsThe incidence of CTS was highest in patients in the age of 40s, in the moderate obesity group, in females, and in patients with diabetes mellitus (DM). The hazard ratio analysis revealed that the following risk factors were strongly related to the occurrence of CTS: age of 40s, female, obesity, DM, rheumatoid arthritis, gout, and Raynaud’s syndrome. However, ESRD, hypothyroidism and smoking were not correlated with CTS occurrence.Conclusions and RelevanceIn our large-scale cohort study, risk factors such as being in one’s 40s, obesity, being female, suffering from DM, and rheumatoid arthritis were reaffirmed as those of CTS occurrence.

Context: There has been an increasing interest in epidemiological and clinical studies concerning the role of uric acid in cardiometabolic diseases, especially in children and adolescents. However, these potential relationships remain undiscovered; accordingly, its pathophysiological mechanisms remain unrecognized. This study aimed to assess the potential association between Serum Uric Acid (SUA) levels and cardiometabolic risk factors in a population-based sample of Iranian children and adolescents. Objectives: This study aimed to assess the potential association between Serum Uric Acid (SUA) levels and cardiometabolic risk factors in a population-based sample of Iranian children and adolescents. Methods: The data of 595 individuals aged 7-18 years were assessed in this research. Anthropometric measurements and laboratory tests were performed according to standardized protocols. Results: The Mean±SD age of the 595 explored students was 12.39±3.07 years. The overall Mean±SD SUA level of the study participants was measured as 4.22±1.13 mg/dL, with significant gender-wise differences (4.04±0.97 mg/dL vs 4.38±1.24 mg/dL, respectively; P<0.05). The prevalence of hyperuricemia based on the 90th percentile of SUA levels was equal to 10.6%. There was a positive association between SUA levels and abdominal obesity (waist circumference: ≥90th percentile) [Odds Ratio (OR): 1.54; 95% Confidence Interval (CI): 1.26 to 1.86] and general obesity [gender-specific Body Mass Index (BMI) for >95th percentile] (OR: 2.32; 95% CI: 1.74 to 3.11). Conclusions: This study suggested BMI and waist circumference as cardiometabolic risk factors, i.e. significantly associated with SUA levels in children and adolescents.

Abstract Evidence shows that chronic rhinosinusitis (CRS) is associated with prior presence of autoimmune diseases; however, large-scale population-based studies in the literature are limited. We conducted a population-based case–control study investigating the association between CRS and premorbid autoimmune diseases by using the National Health Insurance Research Database in Taiwan. The CRS group included adult patients newly diagnosed with CRS between 2001 and 2013. The date of diagnosis was defined as the index date. The comparison group included individuals without CRS, with 1:4 frequency matching for gender, age, and index year. Premorbid diseases were forward traced to 1996. Univariate and multivariate logistic regression was performed to estimate odds ratios (ORs) and 95% confidence intervals. The CRS group consisted of 30,611 patients, and the comparison group consisted of 122,444 individuals. Patients with CRS had a higher significant association with premorbid autoimmune diseases (adjusted OR 1.39 [1.28–1.50]). Specifically, patients with CRS had a higher significant association with ankylosing spondylitis, polymyositis, psoriasis, rheumatoid arthritis, sicca syndrome, and systemic lupus erythematosus (adjusted OR 1.49 [1.34–1.67], 3.47 [1.12–10.8], 1.22 [1.04–1.43], 1.60 [1.31–1.96], 2.10 [1.63–2.72], and 1.69 [1.26–2.25]). In subgroup analysis, CRS with and without nasal polyps demonstrated a significant association with premorbid autoimmune diseases (adjusted OR 1.34 [1.14–1.58] and 1.50 [1.38–1.62]). In addition, CRS with fungal and non-fungal infections also demonstrated a significant association with premorbid autoimmune diseases (adjusted OR 2.02 [1.72–2.49] and 1.39 [1.28–1.51]). In conclusion, a significant association between CRS and premorbid autoimmune diseases has been identified. These underlying mechanisms need further investigation.

Abstract Purpose The association between height and the risk of developing primary brain malignancy remains unclear. We evaluated the association between height and risk of primary brain malignancy based on a nationwide population-based database of Koreans. Methods Using data from the Korean National Health Insurance System cohort, 6,833,744 people over 20 years of age that underwent regular national health examination were followed from January 2009 until the end of 2017. We documented 4,771 cases of primary brain malignancy based on an ICD-10 code of C71 during the median follow-up period of 7.30 years and 49,877,983 person-years. Results When dividing the population into quartiles of height for each age group and sex, people within the highest height quartile had a significantly higher risk of brain malignancy, compared to those within the lowest height quartile (HR 1.21 CI 1.18–1.32) after adjusting for potential confounders. We also found that the risk of primary brain malignancy increased in proportion with the quartile increase in height. After analyzing subgroups based on older age (≥ 65) and sex, we found positive relationships between height and primary brain malignancy in all subgroups. Conclusions This study is the first to suggest that height is associated with increased risk of primary brain malignancy in the East-Asian population. Further prospective and larger studies with precise designs are needed to validate our findings.

Introduction Assessing the risk factors for and consequences of infection with SARS-CoV-2 during pregnancy is essential to guide clinical guidelines and care. Previous studies on the influence of SARS-CoV-2 infection in pregnancy have been among hospitalised patients, which may have exaggerated risk estimates of severe outcomes because all cases of SARS-CoV-2 infection in the pregnant population were not included. The objectives of this study were to identify risk factors for and outcomes after SARS-CoV-2 infection in pregnancy independent of severity of infection in a universally tested population, and to identify risk factors for and outcomes after severe infection requiring hospital admission. Material and Methods This was a prospective population-based cohort study in Denmark using data from the Danish National Patient Register and Danish Microbiology Database and prospectively registered data from medical records. We included all pregnancies between March 1 and October 31, 2020 and compared women with a positive SARS-CoV-2 test during pregnancy to non-infected pregnant women. Cases of SARS-CoV-2 infection in pregnancy were both identified prospectively and through register linkage to secure that all cases were identified and that cases were pregnant during infection. Main outcome measures were pregnancy, delivery, maternal, and neonatal outcomes. Severe infection was defined as hospital admission due to COVID-19. Results Among 82 682 pregnancies, 418 women had SARS-CoV-2 infection during pregnancy, corresponding to an incidence of 5.1 per 1000 pregnancies, 23 (5.5%) of which required hospital admission due to COVID-19. Risk factors for infection were asthma (OR 2.19 [1.41-3.41]) and being foreign born (OR 2.12 [1.70-2.64]). Risk factors for hospital admission due to COVID-19 included obesity (OR 2.74 [1.00-7.51]), smoking (OR 4.69 [1.58-13.90]), infection after gestational age (GA) 22 weeks (GA 22-27 weeks: OR 3.77 [1.16-12.29]; GA 28-36 weeks: OR 4.76 [1.60-14.12]) and having asthma (OR 4.53 [1.39-14.79]). We found no difference in any obstetric or neonatal outcomes. Conclusions Only 1 in 20 women with SARS-CoV-2 infection during pregnancy require admission to hospital due to COVID-19. And severe outcomes of SARS-CoV-2 infection in pregnancy are rare.

Abstract Background The rapidly increasing coincidence of thyroid cancer and metabolic syndrome (MS) in recent decades suggests an association between the two disorders. To investigate this association, we conducted a nationwide study of a large-scale patient cohort. Methods Between 2009 and 2011, data were collected by the Korean National Health Insurance Service for 4,658,473 persons aged 40–70 years without thyroid cancer. During the 6-year follow-up period, participants were monitored for the development of thyroid cancer. The relative risks and incidences of thyroid cancer were calculated using multivariate Cox proportional hazards regression analyses after adjusting for age and body mass index. Results At the end of the study, 47,325 subjects (1.0%) were newly diagnosed with thyroid cancer. The risk of thyroid cancer was significantly elevated in men and women with MS or MS components, except for hyperglycaemia (p = 0.723) or hypertriglyceridemia (p = 0.211) in men. The incidence of thyroid cancer per 10,000 person-years in individuals with MS was significantly higher in men (6.2, p < 0.001) and women (21.3, p < 0.001) compared to those without MS. Additionally, the risk of thyroid cancer increased significantly with an increasing number of MS components even in individuals with only one or two MS components. Conclusions MS and its components were significantly associated with increased risk of developing thyroid cancer. Patients with MS or MS components should be regularly screened for thyroid cancer to enable swift therapeutic response in this at-risk population.

When studying the range of toxic substances triggering dementia, special attention should be paid to the materials used in dental practice, particularly to dental fillings containing amalgam. This necessitated conducting large-scale epidemiologic studies. The aim of our research was to determine the risk factors for developing dementia when filling materials containing amalgam are used in dental practice. In order to achieve the set goals, the following tasks were undertaken: (1) The social and demographic characteristics of the examined patients were studied; (2) the spectrum of concomitant somatic diseases was determined in patients of different gender and age; and (3) the relationship between dementia incidence and the volume of dental filling material containing amalgam was identified in patients with different somatic diseases. In general, the research conducted did not reveal any direct relationship between the development of dementia and the volume of filling material containing amalgam. However, among the people with dementia, there were persons for whom its progression was accelerated in cases where a large volume of dental filling material containing amalgam was present.

Abstract Epidemiologic studies of childhood leukemia have made limited use of tumor genetic characteristics, which may be related to disease etiology. We characterized the cytogenetics of 543 childhood leukemia patients (0–14 years of age) enrolled in the Northern California Childhood Leukemia Study, an approximately population-based study comprised primarily of Hispanics (42%) and non-Hispanic whites (41%), and compared the cytogenetic profiles between these two ethnic groups. Subjects were classified by immunophenotypes, conventional cytogenetic characteristics, and fluorescence in situ hybridization findings. The abnormalities most frequently observed among all patients were pseudodiploidy and high hyperdiploidy (51–67 chromosomes) (27% and 25%, respectively). No ethnic differences in the frequency of 11q23/MLL rearrangements were observed between Hispanics and non-Hispanic whites. Among B lineage ALL patients without 11q23/MLL rearrangements, the percentage of TEL-AML1 translocations was significantly lower in Hispanics (13%) than in non-Hispanic whites (24%; P = 0.01). This is the first large study to compare frequencies of cytogenetic events of primarily Hispanic and non-Hispanic white childhood leukemia patients. Our data suggest some cytogenetic characteristics likely differ between non-Hispanic whites and Hispanics. The mechanistic basis for the two-fold variation in frequency of TEL-AML1 may be due to ethnic-specific risk factors or genetics and should be explored further. Owing to the heterogeneity of leukemia in children, it is possible that cytogenetic subgroups may have distinct etiologies and risk factors which otherwise would be overlooked with the broad leukemia subtypes (e.g. ALL, AML) presently used in epidemiologic analyses.

Background: The prevalence of obesity, one risk factor for developing the metabolic syndrome (MS), has increased during the last decades. It has therefore been assumed that the prevalence of MS would also increase. Aims: The aim was to analyse the prevalence of MS and its risk factors in a middle-aged Swedish population. Methods: Data were obtained between 2003 and 2004 from a random population based sample of 502 men and 505 women, 45–69 years old. Measures of plasma glucose, serum lipids, blood pressure, weight, height, waist circumference and self-reported data concerning presence of disease, medication and lifestyle were obtained. Results: The prevalence of MS was 14.8% among men and 15.3% among women, with an increase by age among women only, 10% to 25% ( p = 0.029). Among individuals with MS the most frequent risk factor was large waist circumference, present in 85% of men and 99% of women, followed by high blood pressure, high triglycerides, high glucose and HDL cholesterol (38% and 47% respectively). Conclusion: The prevalence of MS was 15%, increasing with age only among women. Overweight was a dominant characteristic, and only half of the individuals with MS had glucose/HDL cholesterol levels beyond defined cut points of the syndrome.
