Background: Research has reported that atopic dermatitis degrades the quality of life of adults in their 20s and 30s. This study, therefore, explored factors associated with improvement of atopic dermatitis in adults in their 20s and 30s. Methods: Three hundred and forty-eight adults who had been diagnosed with atopic dermatitis (recovery group, 146; atopic group, 202) in the Korean National Health and Nutrition Examination Survey (2016–2018) were selected for this study. Complex sample descriptive, crosstab, and logistic analyses were used to identify significant factors associated with improvement of atopic dermatitis in adults in terms of sociodemographic characteristics, lifestyle, mental health, and physical activity. Results: Among several sociodemographic characteristics, the significant factors were age, sex, and marital status. When these factors were included as covariates in logistic regression models, adults were more likely to be in the recovery group if they thought positively about their health condition, if their stress recognition was low, and if they had enough sleep time during the week. Furthermore, adults were more likely to be in the recovery group if they were engaged in high- and moderate-intensity activities at work and leisure. Conclusion This study showed that positive mental health, sufficient sleep time, and high- and middle-intensity activities are important factors associated with improvement of atopic dermatitis in adults in their 20s and 30s. We expect that these findings will help improve the quality of life in young working adults who suffer from atopic dermatitis.

This study assesses the fertilization and blastocyst-forming rate in mice cumulus-oocyte complexes (COCs) after the exposure of human ovarian endometriotic fluid. Endometriotic fluid was obtained from a single patient by aspiration at the time of a laparoscopic cystectomy and serially diluted. COCs were obtained from 46-week-old female BDF1 mice. After exposure to ovarian endometriotic fluid for five minutes, the COCs were washed three times and the oocytes were then fertilized by mice sperm. The fertilization and blastocyst formation rate and the proportion of hatching/hatched blastocyst in the four treatment groups were not inferior to those in non-exposure group.

OBJECTIVES: Childhood depressive disorder one of the most prevalent chronic health conditions affecting school aged children. The objective of this study was to examine the prevalence and epidemiological characteristics of childhood depressive disorder in Korea. METHODS: In this study, a survey was conducted of elementary school children in the Cheonan area from September 2009 to August 2010. A total of 12,084 children were included in the analyses. The primary measure of depression was the 27-item Kovacs' Children's Depression Inventory (CDI), the Korean Dupaul attention-deficit hyperactivity disorder Rating Scales (K-ARS), Autism Spectrum Screening Questionnaire (ASSQ) and Restless Legs Syndrome Questionnaire (RLSQ) were also administered. RESULTS: The prevalence rate of childhood depressive disorder was 3.07%. The mean age was 9.21+/-1.81 years for the control group (5,969 male, 6,054 female) and 9.91+/-1.83 years for the depression group (CDI score> or =22 ; 159 male, 210 female). Age, height, weight, and economic status were similar for the two groups. However, there were statistically significant differences in the distribution of sex. The distribution of school grade also differed between the two groups. Scores for CDI, K-ARS, and ASSQ in the depressive group were higher than those of the control group. CONCLUSIONS: This is the first large-scale population-based study to report on the prevalence of childhood depressive disorder in South Korea. Increased rates of childhood depressive disorder, as reported by primary caretakers, might reflect the increasing negative impact of environmental risk factors on neurobehavioral health. Longitudinal study of the prevalence of childhood depressive disorder should be considered for further evaluation.

BACKGROUND: The associations of vitamin D deficiency with various clinical conditions highlighted the importance of vitamin D testing. Currently, clinicians measure only the total 25-hydroxyvitamin D [25(OH)D] concentration, regardless of its bioavailability. We aimed to determine the effect of vitamin D-binding protein (VDBP) on 25(OH)D bioavailability. METHODS: Serum samples were collected from 60 healthy controls, 50 pregnant women, and 50 patients in intensive care units (ICUs). Total 25(OH)D was quantified by liquid chromatography with tandem mass spectrometry, and VDBP levels were determined by using an ELISA kit (R&D Systems, USA). The bioavailable 25(OH)D levels were calculated by using total 25(OH)D, VDBP, and albumin concentrations. RESULTS: In comparison with healthy controls, the total 25(OH)D concentration was significantly lower in ICU patients (median, 11.65 vs 18.25 ng/mL; P<0.00001), but no significant difference was noted between pregnant women (18.25 ng/mL) and healthy controls. The VDBP level was significantly lower in ICU patients (95.58 vs 167.18 µg/mL, P=0.0002) and higher in pregnant women (225.01 vs 167.18 µg/mL, P=0.008) compared with healthy controls. Nonetheless, the calculated bioavailable 25(OH)D levels of ICU patients and pregnant women were significantly lower than those of healthy controls (1.97 and 1.93 ng/mL vs 2.56 ng/mL; P=0.0073 and 0.0027). CONCLUSIONS: A single marker of the total 25(OH)D level is not sufficient to accurately evaluate vitamin D status, especially in pregnant women. In cases where VDBP concentrations may be altered, VDBP measurements and bioavailable 25(OH)D calculations may help to determine vitamin D status accurately.

PURPOSE: Transforming growth factor-beta1 (TGF-beta1) has an important role in the pathogenesis of renal damage; it enhances extracellular matrix production. Urinary TGF-beta1 excretion has been shown to be significantly increased in patients with IgA nephropathy. The aim of the present study was to evaluate the effect of spironolactone on urinary TGF-beta1 levels in patients with IgA nephropathy. METHODS: TGF-beta1 was measured by enzyme-linked immunosorbent assay in random urine specimens from 35 patients with IgA nephropathy. The patients were assigned to a spironolactone group, prednisolone group or losartan group. They were treated over an 8-week period. Urine samples were tested at the beginning and the end of the treatment period. RESULTS: The patients with IgA nephropathy (n=35) had a higher urinary excretion of TGF-beta1 than normal controls (n=13). Urinary TGF-beta1 excretion was positively correlated with proteinuria and pathological grading but not with serum creatinine. After 8 weeks of treatment, losartan (n=13) and prednisolone (n=11) therapy induced a significant reduction in both urinary protein and TGF-beta1 excretion. After treatment with spironolactone (n=11), urinary protein and TGF-beta1 excretion were decreased. However, the decrease was not statistically significant. There was a significant correlation between the urinary TGF-beta1 excretion and the serum aldosterone (r=0.84; p<0.01); however, treatment with spironolactone abolished this correlation. CONCLUSION: This study provides evidence that endogenous aldosterone influences urinary TGF-beta1 excretion in patients with IgA nephropathy.

BACKGROUND: Soluble suppression of tumorigenicity 2 (sST2) has emerged as a novel biomarker for heart failure, and serum sST2 concentrations could be increased in inflammatory diseases. We explored whether sST2 is related to cardiac dysfunction/failure and has a prognostic role in patients with suspected sepsis. METHODS: In a total of 397 patients with suspected sepsis, sST2 concentrations were measured by using the Presage ST2 Assay (Critical Diagnostics, USA). sST2 concentrations were analyzed according to procalcitonin (PCT) concentrations, cardiovascular subscores of the sepsis-related organ failure assessment (SOFA) score, and clinical outcomes. RESULTS: sST2 concentrations were increased significantly according to the five groups of PCT concentrations and cardiovascular subscores of the SOFA score (P<0.000001 and P=0.036, respectively). In-hospital mortality was significantly higher among patients with sST2 concentrations above 35 ng/mL (P=0.0213) and among patients with increased concentrations of both sST2 and PCT (P=0.0028). CONCLUSIONS: sST2 seems to be related to both cardiac dysfunction/failure and severity in sepsis. Measurement of sST2 and PCT in combination would be useful for risk stratification and prognosis prediction in patients with suspected sepsis.

PURPOSE: Cockroach feces are known to be rich in IgE-reactive components. Various protease allergens were identified by proteomic analysis of German cockroach fecal extract in a previous study. In this study, we characterized a novel allergen, a chymotrypsin-like serine protease. METHODS: A cDNA sequence homologous to chymotrypsin was obtained by analysis of German cockroach expressed sequence tag (EST) clones. The recombinant chymotrypsins from the German cockroach and house dust mite (Der f 6) were expressed in Escherichia coli using the pEXP5NT/TOPO vector system, and their allergenicity was investigated by ELISA. RESULTS: The deduced amino acid sequence of German cockroach chymotrypsin showed 32.7 to 43.1% identity with mite group 3 (trypsin) and group 6 (chymotrypsin) allergens. Sera from 8 of 28 German cockroach allergy subjects (28.6%) showed IgE binding to the recombinant protein. IgE binding to the recombinant cockroach chymotrypsin was inhibited by house dust mite chymotrypsin Der f 6, while it minimally inhibited the German cockroach whole body extract. CONCLUSIONS: A novel allergen homologous to chymotrypsin was identified from the German cockroach and was cross-reactive with Der f 6.

The purpose of this study was to compare the nutritional status of children aged 5 or under and women aged 20 to 34 years between the Republic of Korea (South Korea) and the Democratic Peoples' Republic of Korea (DPRK: North Korea). For the source of nutritional status of North Koreans, the DPRK 2004 Nutrition Assessment-Report of Survey Results was used. As the comparable data of South Koreans, the anthropometric data for children and women were obtained from the reports of the Korean Pediatric Society and the Korean Agency for Technology and Standards, respectively. The blood hemoglobin data of South Korean women were obtained from the data file of the 2001 National Health and Nutrition Survey and analyzed. In regard to the North Korea, the prevalence of underweight (weight for age Z-score <-2.0) in children under 12 months was about 10~15%, and thereafter progressively increased until 30 to 35 months reaching 30%. In South Korea, the prevalence of underweight was less than 3% in most age groups both in boys and girls. In North Korea, the prevalence of stunting (height for age Z-score <-2.0) reached 20% in children under 12 months and increased with age over the level of 50% in children aged 54 to 59 months. In South Korea, the prevalence of stunting was less than 3% in children under 12 months and was less than 10% throughout the age groups. Maternal protein-energy malnutrition and anemia were assessed for the women aged 20 to 34 years using mid-upper arm circumference (< 22.5 cm) and blood hemoglobin level (< 12 g/DL), respectively. The prevalence of protein-energy malnutrition was 39.6%, 30.7%, 31.7% in North Korea and 12.5%, 5.0%, 1.5% in South Korea for the women in 20~24, 25~29, 30~34 years, respectively. The prevalence of anemia in the North Korean women was about 34~36% while that in the South Korean women was 15~18%. In conclusion, the disparity of nutritional status in early childhood and maternity between South Korea and North Korea is so huge that active and well-planned nutrition support policy and programs for women and children in North Korea is imperative to prepare for the future unified nation.

OBJECTIVE: Mid-sized hospital websites were assessed to examine how their attributes influence outcome indicators as a potential marketing strategy. Specifically, the website attributes considered were accessibility, content sufficiency, and layout design, while outcome indicators were evaluated, based on satisfaction with the website, intention to revisit the website, and intention to recommend the hospital. METHODS: Five representative websites were selected according to their ranks derived from major ranking sites. The diversity of the websites were emphasized. Then, a questionnaire survey was conducted on 74 respondents. Collected data was analyzed, using frequency, correlation, and repeated measures analysis of variance. RESULTS: All three attributes were related to satisfaction with the website; in addition, both content sufficiency and layout design were significantly related to the intention to revisit. As for the intention to recommend the hospital, only the content sufficiency was significant. In particular, the sufficiencies on 'disease or symptoms' and 'question and answer' were important to all three outcome indicators. CONCLUSION: The websites serve as a marketing tool in managing mid-sized hospitals. Well-designed websites containing sufficient contents facilitate visitor's satisfaction and intention to revisit the website, as well as furthering their intention to recommend the hospital.
