Prolonged skin inflammation is caused by disrupted skin barrier resulting in chronic inflammatory diseases such as atopic dermatitis. As a potent natural product with anti-inflammatory property, Aster glehni (A. glehni) is a traditional edible herb and has been used to treat diabetes or colitis-associated colon cancer. In present study, we figured out an additional effect of A. glehni ethanol extract (AGE) in pro-inflammatory cytokines-stimulated human keratinocytes. Mixture of tumor necrosis factor-alpha (TNF-α) and interferongamma (IFN-γ) was used to induce inflammatory responses in the HaCaT keratinocytes. AGE suppressed activation of ERK mitogen-activated protein kinase, nuclear factor (NF)-κB, and signal transducer and activator of transcription 1 and 3 (STAT1 and STAT3). The treatment of AGE inhibited mRNA expressions of proinflammatory cytokines in TNF-α and IFN-γ-stimulated HaCaT cells. Also, AGE induced up-regulated expressions of skin barrier molecules like filaggrin, loricrin, or ZO-1. We evaluated the effects of AGE on protein or mRNA expression levels using western blot or qRT-PCR, respectively. Taken together, these results suggest that the treatment of AGE exerts anti-inflammatory effect on keratinocytes through suppressing inflammatory signaling pathways and up-regulating skin molecules in HaCaT keratinocytes.

Accurate occupation classification is essential in various fields, including policy development and epidemiological studies. This study aims to develop an occupation classification model based on DistilKoBERT.

Objectives: This study aimed to propose an efficient mental health service plan to be implemented during epidemics by identifying the mental health characteristics of people who have returned from countries with large-scale coronavirus disease-2019 (COVID-19) outbreaks. Methods: We analyzed the mental health evaluation scale data submitted by 504 quarantined people who had returned from countries hit by the COVID-19 pandemic from January to April 2020 through a government support project. Results: The average age of the study group was 35.6±8.72 years, and males accounted for 67.1% and females 32.9% of the total subjects. The screening score for post-traumatic stress disorder was met by 12.1% of the subjects. Moderate to high level of depression and anxiety symptoms were seen in 10.7% and 7.0%, respectively. Also, 2.2% of the group complained of clinical level somatization symptoms, and 1.4% were evaluated as being at a high risk of suicide. The average scores and the proportion of subjects at high risk on all scales were significantly higher in female than in male. In a comparison by age, the average score of post-traumatic stress symptoms was significantly higher in subjects in their 20s than those in their 50s, and the proportion of the subjects at high risk for post-traumatic stress symptoms also showed a significant variation between age groups. However, there were no significant differences by age with respect to depression, anxiety, somatic symptoms, and suicidal tendencies. Conclusion During an epidemic, the mental health problems of people may increase, and the risk appears to be higher in female and young adults. Therefore, in addition to strong protection policies, a customized support system for each target group is required.

Background: Although respiratory tract infection is one of the most important factors triggering acute exacerbation of chronic obstructive pulmonary disease (AE-COPD), limited data are available to suggest an epidemiologic pattern of microbiology in South Korea. Methods: A multicenter observational study was conducted between January 2015 and December 2018 across 28 hospitals in South Korea. Adult patients with moderate-to-severe acute exacerbations of COPD were eligible to participate in the present study. The participants underwent all conventional tests to identify etiology of microbial pathogenesis. The primary outcome was the percentage of different microbiological pathogens causing AE-COPD. A comparative microbiological analysis of the patients with overlapping asthma–COPD (ACO) and pure COPD was performed. Results: We included 1,186 patients with AE-COPD. Patients with pure COPD constituted 87.9% and those with ACO accounted for 12.1%. Nearly half of the patients used an inhaled corticosteroid-containing regimen and one-fifth used systemic corticosteroids. Respiratory pathogens were found in 55.3% of all such patients. Bacteria and viruses were detected in 33% and 33.2%, respectively. Bacterial and viral coinfections were found in 10.9%. The most frequently detected bacteria were Pseudomonas aeruginosa (9.8%), and the most frequently detected virus was influenza A (10.4%). Multiple bacterial infections were more likely to appear in ACO than in pure COPD (8.3% vs. 3.6%, p=0.016). Conclusion Distinct microbiological patterns were identified in patients with moderate-to-severe AE-COPD in South Korea. These findings may improve evidence-based management of patients with AE-COPD and represent the basis for further studies investigating infectious pathogens in patients with COPD.
