Cavernous lymphangiomas, characterized by the cystic enlargement of lymphatic vessels in the dermis and subcutaneous tissue, are rarely reported in the scalp. We present the case of a 6-month-old male infant with occipital scalp swelling, whose ultrasonographic examination identified a multiseptated hypoechoic mass in the subcutaneous layer. Histologically, the tumor exhibited irregular, dilated spaces lined with a single layer of endothelial cells, showing D2-40 positivity. This represents a rare case of pediatric cavernous lymphangioma of the scalp, accompanied by a literature review.

Objective: Recently, various mental health promotion programs using virtual reality (VR) technology have been tried in the psychiatric field. Considering the importance of mental health in pregnant women, VR-assisted mental health promotion programs for pregnant women are needed to be developed. This study aimed to prospectively investigate the efficacy of a VR-assisted mental health promotion program for pregnant women. Methods: Fifty-five pregnant women were participated in this study. Mental health states such as depression, anxiety, perceived stress, and quality of life were assessed by Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), Perceived Stress Scale, and World Health Organization Quality of Life Scale Abbreviated Version (WHOQOL-BREF) before and after using VR program treatment. Based on the mental health types of pregnant women classified by cluster analysis, the effects of the VR program were analyzed by paired t test and Wilcoxon signed rank test. Results: The VR program significantly reduced PHQ-9 (p = 0.033) and GAD-7 (p = 0.046) scores, and significantly increased WHOQOL-BREF (p = 0.026) score of the participants. Additionally, when classifying the mental health types of pregnant women, the VR program was significantly effective to improve depression, anxiety, and quality of life in the most severe group based on the cluster analysis. Conclusion The results of this study suggest that VR program may be effective to improve the mental health of pregnant women. Particularly, VR programs for the high-risk group of depression might be the most effective. Therefore, VR-assisted mental health promotion programs could be useful for managing the mental health in pregnant women.

Background: The coronavirus disease 2019 (COVID-19) pandemic has significantly impacted global infrastructure. We surveyed laboratories to analyze the changes in testing methods and procedures to improve future pandemic preparedness. Methods: This study surveyed laboratory physicians and technologists in South Korea and analyzed responses from 126 of 323 institutions. The survey was conducted in May 2023 using the proficiency test of the Korean Association of External Quality Assessment Service and examined the diagnostic procedures, personnel, equipment, and quality control. The survey comprised 15 questions covering respondent demographics, public-private proficiency projects, COVID-19 testing procedures, and laboratory status. Results: Of the 126 laboratories, 66.7% performed bacterial smear and culture, 65.9% had biosafety level 2 facilities, and 39.7% had separate nucleic acid extraction areas. Furthermore, 98.4% of the laboratories had biological safety cabinets, the median number of PCR machines was four units, and 77.8% had autoclaves. The median numbers of personnel managing and conducting tests were one and three, respectively. Additionally, 88.1% of the laboratories found the COVID-19 proficiency test helpful, with key benefits in terms of accuracy and skill improvement. COVID-19 tests were primarily used for symptomatic or contact person testing, pre-admission screening, and periodic proactive testing. Specialized testing laboratories conducted up to 50,000 tests daily, and tertiary hospitals conducted up to 1,500 tests.Emergency, pooled, and rapid antigen tests were widely used. Most respondents wanted future tests for respiratory viruses, bacteria, and viral diarrhea, indicating a willingness to participate. Conclusion Aggressive testing and collaboration between health agencies and laboratories are crucial for managing emerging diseases. Systematic preparations are essential to maintain and strengthen laboratory capabilities for future infectious disease outbreaks.

As South Korea transitions into a super-aged society, addressing the challenges of aging through tailored nutritional strategies is becoming increasingly critical. This study developed a hemp seed soup designed for the elderly, using the functional benefits of hemp, a nutrient-dense ingredient rich in dietary proteins, essential fatty acids, polyphenols, and antioxidants. Soups were formulated with varying levels of hemp seed powder (0% (CS), 25% (HS25S), 50% (HS50S), and 75% (HS75S)), to address the dietary needs and physiological characteristics of the elderly, including mastication and swallowing difficulties. Increasing the hemp seed powder levels significantly enhanced the crude protein, total polyphenol, and flavonoid contents while improving the antioxidant activities, as assessed by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging assays. HS75S exhibited the highest nutritional values and antioxidant activity. By contrast, food texture analysis showed that the viscosity decreased at higher hemp seed concentrations, with HS25S and HS50S demonstrating favorable textures for elderly consumption.Consumer acceptance testing identified HS50S as the most preferred sample, scoring highest in flavor, texture, and overall acceptability. This study highlights the potential of hemp seeds as a functional ingredient in developing nutritious and elderly-friendly food products. The hemp seed soup, with its enhanced protein, antioxidant properties, and tailored texture, offers a promising solution to improve the nutritional status and health of the elderly. Future studies should explore the long-term health benefits of hemp seed soup and its integration with other functional ingredients to optimize the sensory and nutritional properties.
