ABSTRACT

Background@#Atopic dermatitis (AD) is a heterogeneous disease with different age of onset, disease course, clinical symptoms, severity, and risk of comorbidity. The characteristics of children with AD also vary by age or country. However, little is known about the clinical characteristics of AD in Korean school-aged children and adolescents. Furthermore, there are few studies on phenotypic differences according to onset age. This study aimed to explore the clinical characteristics and phenotypes according to onset age and severity of AD in children and adolescents in Korea. @*Methods@#AD patients aged 6–18 years who presented to 18 hospitals nationwide were surveyed.The patients were examined for disease severity by pediatric allergy specialists, and data on history of other allergic diseases, familial allergy history, onset age, trigger factors, lesion sites,treatment history and quality of life were collected. The results of the patient’s allergy test were also analyzed. The patients were classified into infancy-onset (< 2 years of age), preschoolonset (2–5 years of age), and childhood-onset (≥ 6 years of age) groups. Study population was analyzed for clinical features according to onset-age groups and severity groups. @*Results@#A total of 258 patients with a mean age of 10.62 ± 3.18 years were included in the study. Infancy-onset group accounted for about 60% of all patients and presented significantly more other allergic diseases, such as allergic rhinitis and asthma (P = 0.002 and P = 0.001, respectively). Food allergy symptoms and diagnoses were highly relevant to both earlier onset and more severe group. Inhalant allergen sensitization was significantly associated with both infancy-onset group and severe group (P = 0.012 and P = 0.024, respectively). A family history of food allergies was significantly associated with infancyonset group (P = 0.036). Severe group was significantly associated with a family history of AD, especially a paternal history of AD (P = 0.048 and P = 0.004, respectively). Facial (periorbital, ear, and cheek) lesions, periauricular fissures, hand/foot eczema, and xerosis were associated with infancy-onset group. The earlier the onset of AD, the poorer the quality of life (P = 0.038). Systemic immunosuppressants were used in only 9.6% of the patients in the severe group. @*Conclusion@#This study analyzed the clinical features of AD in Korean children and adolescents through a multicenter nationwide study and demonstrated the phenotypic differences according to onset age and severity. Considering the findings that the early-onset group is more severe and accompanied by more systemic allergic diseases, early management should be emphasized in young children and infants.

ABSTRACT

Asthma is a heterogeneous disease whose development is shaped by a variety of environmental and genetic factors. While several recent studies suggest that microbial dysbiosis in the gut may promote asthma, little is known about the relationship between the recently discovered lung microbiome and asthma. Innate lymphoid cells (ILCs) have also been shown recently to participate in asthma. To investigate the relationship between the lung microbiome, ILCs, and asthma, we recruited 23 healthy controls (HC), 42 patients with non-severe asthma, and 32 patients with severe asthma. Flow cytometry analysis showed severe asthma associated with fewer natural cytotoxicity receptor (NCR) + ILC3s in the lung.Similar changes in other ILC subsets, macrophages, and monocytes were not observed. The asthma patients did not differ from the HC in terms of the alpha and beta-diversity of the lung and gut microbiomes. However, lung function correlated positively with both NCR + ILC3 frequencies and microbial diversity in the lung. Sputum NCR + ILC3 frequencies correlated positively with lung microbiome diversity in the HC, but this relationship was inversed in severe asthma. Together, these data suggest that airway NCR + ILC3s may contribute to a healthy commensal diversity and normal lung function.

ABSTRACT

Background@#This study aims to identify the differences between climacteric symptoms, climacteric symptoms management, and well-being according to the D-type personality, and to determine the degree of influence of the D-type personality on the well-being. @*Methods@#A correlational, cross-sectional research design was used with 169 middle-aged women. Data collection was performed using a structured questionnaire between July and August 2020. Data analyses included descriptive statistics, independent t-test, one-way ANOVA, X2 -test, ANCOVA, Pearson’s correlation coefficient, and hierarchical regression analysis were performed with the SPSS WIN 27.0 program. @*Results@#Type-D personality was identified in 34.3%. Type D women had significantly higher climacteric symptoms, lower climacteric symptoms management and well-being compared with non-type D women. In addition, type D personality had the strongest association with well-being among middle-aged women, followed by climacteric symptoms and climacteric symptoms management. @*Conclusions@#Interventions that reflect climacteric symptoms and climacteric symptoms management, including type-D personality, may help enhance well-being for middle-aged women in nursing practice.

ABSTRACT

Objective@#Medication beliefs are a significant determinant of medication adherence in chronic illness. This study aimed to identify demographic, clinical, and medication-related factors associated with medication beliefs in patients with Parkinson’s disease (PD). @*Methods@#We used a descriptive cross-sectional design with a convenience sample of 173 PD patients who had been taking antiparkinson drugs for more than one year. @*Results@#The subjects who believed PD medication was more necessary had more severe illness, younger age of onset, longer illness duration, and longer duration of levodopa therapy. They had higher levels of non-motor symptoms and depression, number of medication uses, number of drugs, and levodopa equivalent dose, and they reported fluctuation of motor symptoms and dyskinesia. The subjects who used catechol-O-methyltransferase (COMT) inhibitors, dopamine agonists, amantadine, and monoamine oxidase-B (MAO-B) inhibitors had significantly higher necessity scores than those who did not use them. The subjects who had higher concerns about PD medications had higher levels of non-motor symptoms and depression. The subjects using amantadine and anticholinergics had significantly higher concern scores than those who did not use them. Positive necessity-concerns differentials were associated with severe illness, the presence of motor fluctuation and dyskinesia, and the use of COMT inhibitors. Based on stepwise multiple regression, the most significant factors influencing necessity beliefs were severe illness, followed by depression and motor fluctuation. @*Conclusion@#Severe illness, higher levels of depression, and motor fluctuation are independent factors influencing patients’ beliefs regarding medication necessity. Therefore, these characteristics should be considered in medication belief assessment and interventions for PD patients.

ABSTRACT

Background/Aims@#Coronary endothelial and microvascular function play important roles in cardiovascular disease. We aimed to evaluate the effect of ticagrelor on coronary artery function and tested the antiplatelet effect of low dose ticagrelor in East-Asian patients. @*Methods@#Sixty-one consecutive patients with non-significant coronary disease were included in the study. Initially, patients were randomized in 1:1:1 ratio to receive drugs: ticagrelor 90 mg twice a day (bid; n = 22), ticagrelor 45 mg bid (n = 19) or clopidogrel 75 mg once a day (qd; n = 20) and then divided into two groups (ticagrelor vs clopidogrel) for evaluation of coronary artery function, and three groups for evaluation of antiplatelet function. Endothelial dysfunction was measured by coronary flow reserve (CFR), and changes in the levels of asymmetric dimethylarginine (ADMA), cluster of differentiation (CD) 40 ligand, and P-selectin. Microvascular function was evaluated as index of microvascular resistance (IMR). Platelet reactivity was assessed by VerifyNow P2Y12 assay. @*Results@#The levels of CFR, ADMA, and CD 40 ligand were not different between the two groups. However, P-selectin was lower in the ticagrelor group compared with clopidogrel group. IMR was significantly lower in the ticagrelor group compared with clopidogrel group (median, 15.0 [interquartile range, 12.0 to 21.0] vs. 47.5 [23.0 to 67.5], p = 0.014). There was significant difference in platelet inhibition among the three groups (ticagrelor 90 mg bid vs. ticagrelor 45 mg bid vs. clopidogrel 75 mg qd; 85.57 ± 47.63 vs. 120.33 ± 51.09 vs. 256.42 ± 55.10, p < 0.001) @*Conclusions@#It is hypothesized that ticagrelor might ameliorate the coronary microvascular function. When compared with clopidogrel, low dose ticagrelor exhibited satisfactory antiplatelet effect in the present study.

ABSTRACT

Purpose@#Key Foods refers to foods that have a high contribution in the nutrient intake of individuals, and exert important effects on their health. This study was undertaken to identify Korean Key Foods, using data from the 7th Korea National Health and Nutrition Examination Survey (KNHNES). @*Methods@#The data source for the extraction of Key Foods was the 24-hour dietary survey data obtained from the 7th KNHNES (2016–2018), and 21,271 subjects were evaluated. A total of 17 nutrients were selected as the key nutrients for identifying the Key Foods, including energy, carbohydrates, protein, lipid, dietary fiber, calcium, phosphorus, iron, sodium, potassium, vitamin A, thiamin, riboflavin, niacin, vitamin C, cholesterol, and sugars. The nutrient consumption approach was applied to generate a list of potential Key Foods. Foods included in 85% of the cumulative intake contribution from one or more key nutrients, were subsequently selected as Key Foods. @*Results@#Of the 1,728 foods consumed by survey respondents, we extracted 728 Key Foods. These Key Foods explained 94% key nutrient intakes of the subjects. Based on the contribution rate to key nutrient intake, the top 10 Key Foods identified were multigrain rice (5.32%), plain white rice (4.23%), milk (3.3%), cabbage kimchi (2.82%), grilled pork belly (1.56%), apples (1.52%), fried eggs (1.49%), cereal (1.36%), instant coffee mix (1.21%), and sweet potatoes (1.12%). These 10 foods accounted for 23.93% total key nutrient intake of the survey respondents. @*Conclusion@#Seven hundred and twenty-eight foods were extracted and identified as the 2020 Korean Key Foods. These Key Foods can be considered the priority foods to be analyzed for establishing a national nutrient database.

ABSTRACT

Purpose@#Congenital pulmonary airway malformation (CPAM) is a rare developmental abnormality of the lungs. We investigated clinical characteristics of CPAM based on patient age at diagnosis. @*Methods@#In this retrospective study, we analyzed the medical records of 51 patients diagnosed with CPAM at Pusan National University Hospital between January 2000 and December 2019. @*Results@#We investigated 39 children and 12 adults. The mean age at the diagnosis of the patients was 15.9± 14.3 years. The mean ages of children and adults at the time of diagnosis of CPAM were 6.8± 5.8 years and 31.2± 10.2 years, respectively. Among the 51 patients investigated, 20 (39%) were asymptomatic and 31 (61%) showed clinical symptoms, such as dry cough, recurrent respiratory infections, and dyspnea at the time of diagnosis. Notably, clinical symptoms at diagnosis were observed in 28 children (72%) and in only 3 adults (25%) (P= 0.006), and children were more symptomatic than adults. Children with large cysts tended to be more symptomatic than those with small cysts (P< 0.001). Combined anomalies were detected in 12 patients (23%). Patients with cystic lesions in the right lower lobe of the lung showed a higher prevalence of combined anomalies (P= 0.015). Surgical resection was performed in 40 patients (78%), and all patients showed good prognosis. @*Conclusion@#This study revealed that the presence of clinical symptoms of CPAM differed between children and adults, depending on the age at diagnosis and that patients with cysts in the right lower lobe of the lungs tended to show a higher prevalence of combined anomalies.

ABSTRACT

Objectives@#The purpose of the present study was to examine the relationship between the chronotype and the burnout, so we investigated the mediating effects of the mediators such as perceived stress, stress response, and depression. @*Methods@#Employees working at Incheon Customs conducted a mental health self-examination through the internet. Among them, 174 people who agreed to the mental health survey participated in the study. Participants completed questionnaires including Composite Scale of Morningness (CSM), Center for Epidemiological Studies-Depression Scale (CES-D), Perceived Stress Scale (PSS), Stress Response Inventory (SRI), Maslach Burnout Inventory-General Survey (MBI-GS). @*Results@#Our results showed a higher degree of CES-D, SRI, exhaustion, and cynicism in evening and intermediate type compared to morning type, and a higher degree of professional efficacy in morning type compared to intermediate type. CSM was shown to have a direct effect on exhaustion and indirect effect through CES-D and SRI. CSM also had a direct effect on professional efficacy and had an indirect effect through the CES-D. However, CSM was found to have only indirect effects through the SRI for Cynicism. @*Conclusions@#In this study, individuals with evening type tend to experience a high degree of burnout (exhaustion, cynicism and professional efficacy) through the mediation effect of depression and stress response. Further study is necessary to reveal the effect of management of the depression and stress response in the employee with evening type.

ABSTRACT

Purpose@#This study was undertaken to develop a nutrition quotient for elementary school children (NQ-C) for evaluating the overall dietary quality and eating behaviors. @*Methods@#The NQ-C was developed by implementing 3 stages: item generation, item reduction, and validation. Candidate food behavior checklist (FBC) items of the NQ-C were derived from systematic literature reviews, expert in-depth interviews, statistical analyses of the fifth Korean National Health and Nutrition Examination Survey data, and national nutrition policies and recommendations. For the pilot survey, 260 elementary school students (128 second graders and 132 fifth graders) completed self-administered questionnaires as well as 24-hour dietary intakes, with the help of their parents and survey team staff, if required. Based on the pilot survey results, expert reviews, and priorities of national nutrition policy and recommendations, checklist items were reduced from 41 to 24. A total of 20 items for NQ-C were finally selected from results generated from 1,144 nationwide samples surveyed. Construct validity of the NQ-C was assessed using the confirmatory factor analysis, LInear Structural RELations. @*Results@#Analyses of the exploratory factors of NQ-C identified that 5 dimensions of diet (balance, diversity, moderation, practice and environment) accounted for 46.2% of the total variance. Standardized path coefficients were used as weights of the items. The NQ-C and 5-factor scores of the subjects were calculated using the obtained weights of the FBC items. @*Conclusion@#Our data indicates that NQ-C is a useful and suitable instrument for assessing nutrition adequacy, dietary quality, and eating behaviors of Korean elementary school children.

ABSTRACT

Purpose@#Trauma is the leading cause of death and disability in children. We aimed to compare the clinical characteristics of children with trauma and disease. @*Methods@#We reviewed the medical records of children (< 19 years) who visited the emergency department of Pusan National University Hospital from 2016 through 2018. Data on the age, age group, sex, details of trauma or disease, severe trauma or disease (Korean Triage Acuity Scale 1-2), hospitalization rate (overall and intensive care unit [ICU]), hospital length of stay, in-hospital mortality, and the Injury Severity Score were compared between the children with trauma and those with disease. @*Results@#In a total of 10,205 children, 3,028 (29.7%) had trauma. The children with trauma were older than those with disease (median age, 78.5 months [interquartile range, 35.0-165.0] vs. 49.0 [16.0-120.0]; P < 0.001). Boys were more common in the former group than the latter (63.7% vs. 56.3%; P < 0.001). The most common injury mechanism was traffic accident (16.0%), followed by fall and foreign body. The overall hospitalization rate was higher in the children with disease (17.1% vs. 35.9%; P < 0.001). However, the children with trauma underwent more frequent ICU hospitalization, and showed higher in-hospital mortality rate and longer hospital length of stay than those with disease (all P < 0.001). The children with severe trauma showed higher median age, percentage of boys, in-hospital mortality, and ICU hospitalization rate, and longer hospital length of stay than those with severe disease (all P < 0.001). @*Conclusion@#Children with trauma tend to be older, and their condition may be more critical in severity than those with disease. This difference is more prominent in those with severe trauma or disease.

ABSTRACT

Nonautoimmune hyperthyroidism is a very rare cause of congenital hyperthyroidism that is usually caused by an activating mutation in the thyroid-stimulating hormone receptor (TSHR) gene. In this report, we describe a case of nonautoimmune hyperthyroidism in a patient with TSHR mutation. Our patient was the younger of a set of twins born at 36 weeks and 6 days of gestation. The patient was noted to be more irritable than the older twin at 80 days of age, and the mother was taking methimazole for Graves’ disease that had been diagnosed 12 years prior. Therefore, a thyroid function test was conducted for the patient. The results revealed subclinical hyperthyroidism, and tests of antithyroglobulin antibody, antithyroid peroxidase antibody, and anti-thyroid-stimulating hormone (TSH) receptor antibody were all negative. During follow-up, at around 4 months of age, free T4 increased to 2.89 ng/dL, and TSH was still low at 0.01 μIU/mL; therefore, 3 mg/day of methimazole was initiated. Whole-exome sequencing showed a heterozygous variant of c.1800C>T (p.Ala627Val) in the TSHR gene. Testing in the family confirmed an identical variant in the patient's mother, leading to diagnosis of familial nonautoimmune hyperthyroidism inherited in an autosomal dominant pattern. This is the second report of A627V confirmed as a germline variant.
