Objective: Perinatal depression often remains undertreated due to concerns about antidepressant exposure during fertility treatment, pregnancy, or breastfeeding. Non-pharmacological, home-based interventions such as transcranial direct current stimulation (tDCS) present a promising alternative; however, real-world evidence in perinatal populations remains limited. Methods: This prospective observational study included 38 women who received infertility, pregnancy, or postpartum treatment at four hospitals in South Korea. Participants self-administered anodal tDCS targeting the left dorsolateral prefrontal cortex for 20–28 sessions over 4 weeks. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D) at baseline and weeks 2, 4, and 8. Subjective health perception was measured at baseline using a 5-point Likert scale. Results: Time had a significant effect on depressive symptoms (Wald χ2=90.75, p<0.001), with the largest reduction observed during the first 2 weeks. The CES-D scores remained significantly lower than baseline at week 8, 4 weeks after treatment ended. Subjective health perception was significantly associated with baseline depression severity (Wald χ2=26.41, p<0.001), and its interaction with time was also significant (Wald χ2=320.18, p<0.001). Participants with poorer perceived health (scores 4–5) experienced greater depressive symptom reductions than those with more favorable perceptions (scores 1–2). Conclusion Home-based tDCS was feasible and associated with clinically meaningful improvement in depressive symptoms among perinatal women. Those who initially perceived their health more negatively showed greater response, suggesting subjective health perception may serve as a useful moderator and potential marker to inform personalized treatment strategies.

The emergence of livestock-associated (LA)-methicillin-resistant Staphylococcus aureus (MRSA) in livestock animal has become a significant zoonotic concern. In the present study, we investigated nationwide prevalence of LA-MRSA across pork production chain including pig farms, slaughterhouses, and retail markets. A total of 40 MRSA strains were isolated during the investigation and the overall prevalence of MRSA was 3.4% (n = 37), 0.6% (n = 2), and 0.4% (n = 1) in pig farms, slaughterhouses, and retail markets, respectively. Multilocus sequence typing analyses revealed that the 2 most significant clonal lineages in pork production chain in Korea were ST398 (n = 25) and ST541 (n = 6). All of the 40 MRSA isolates were further characterized to investigate key genotypic and phenotypic correlates associated with the emergence and spread of clonal complex 398 (CC398; ST398, and ST541) LA-MRSA. Although the prevalence of swine-associated MRSA was still relatively low and mostly restricted to pig farms, multidrug-resistant CC398 LA-MRSA isolates with new spa types (t18102 and t18103) were identified as a major clonal lineage. The CC398 LA-MRSA strains tended to exhibit increased levels of multiple drug resistance (MDR) phenotype compared with non-CC398 MRSA strains. Of note, in comparison with non-CC398 MRSA isolates, CC398 LA-MRSA isolates exhibited significantly enhanced tetracycline (TET) and zinc resistance. These findings suggested that co-selection pressure associated with MDR phenotype, especially TET resistance, and zinc resistance may have played a significant role in the emergence and persistence of CC398 LA-MRSA in pig farms in Korea.

The emergence and prevalence of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible S. aureus (MSSA) in livestock animals have become a worldwide public health concern. While the prevalence and genetic profiles of MRSA strains in pigs and pork meat have been actively studied, livestock-associated MSSA strains have only been characterized in a few small-scale studies. In this investigation, we assessed the nationwide prevalence of MSSA in the Korean pig production chain, including pig farms, slaughterhouses, and retail markets. Among the 41 MSSA strains, the predominant clonal lineages were sequence type (ST) 398 (n = 15, 37%) and ST5 (n = 13, 32%). Although the overall prevalence of MSSA (2.58%) was low and mostly restricted to pig farms, ST398 MSSA strains showed higher level of multidrug resistance phenotype versus non-ST398 MSSA strains. In addition to the MDR phenotype, all of the ST398 MSSA strains exhibited resistance to tetracycline as they harbored the tet(K), tet(L), and/or tet(M) genes. However, ST398 MSSA strains did not exhibit increased resistance to zinc compared with the non-ST398 strains. This study is the first to provide evidence of ST398 MSSA emergence in livestock animals in Korea. Further studies are necessary to elucidate the potential of ST398 MSSA strains for human transmission. Our findings suggest that the MDR phenotype and high levels of tetracycline resistance may have played an important role in the emergence and prevalence of ST398 MSSA in pig farms in Korea.

OBJECTIVES: This study was aimed to identify the socioeconomic factors, health behavior factors and dietary patterns that have an influence on the periodontal disease in adults. METHODS: This study used data collected from the fifth Korea National Health and Nutrition Examination Survey (NHANES V-1). The final sample included 2,386 subjects who were 30-59 years old and who had completed the necessary health examinations, the health behaviors survey and nutrition survey. RESULTS: Eleven dietary patterns emerged from the factor analysis with different factor loading. After controlling for potential confounders, multiple logistic regression analysis of the dietary patterns showed that 'legumes/mixed grains' and 'instant foods' affected the periodontal disease. Lower consumption of 'legumes/mixed grains' and higher consumption of 'instant foods' were significantly associated only with an increased risk of periodontal disease. CONCLUSIONS: In the light of the results of this study, it appears pretty likely that the risk of developing periodontal disease can be reduced by changing a person's dietary patterns.

PURPOSE: This study aimed to examine the relationship between parent's history of allergic disease and children's atopic dermatitis. METHODS: Data from the 2011 Research on the Current Status of Atopic Disease with Elementary Schools and Kindergartens in Suwon were used for analysis. Among 20,052 persons consenting to the survey, 18,943 who had answered parent's history were included in the study. RESULTS: The prevalence of father, mother, and parent's allergic disease history were 8.5%, 9.5%, and 2.3%, respective. The children with atopic dermatitis comprised 15.1% of the study population. In multivariate analysis, gender, weight at birth, the practice of breast-feeding, father's educational level, the presence of chemical products in the inside, and the presence of mold were significant risk factors for children's atopic dermatitis. The multivariate-adjusted odds ratio for the occurrence of children's atopic dermatitis was 3.19 (95% confidence interval, 2.57-3.95) when subjects with and without parent's history were compared. CONCLUSION: When fathers have a history of allergic disease, children tend to have atopic dermatitis.
