Purpose: Neonatal nurses are expected to have clinical competency to provide qualified and safe care for high-risk infants. An educational intervention to enhance nurses’ clinical competence is often a priority in the nursing field. This study was conducted to explore nurses’ perceived importance and performance confidence of nursing care activities in neonatal intensive care units. Methods: One hundred forty-one neonatal nurses from seven hospitals across South Korea participated in the online survey study. The scale of neonatal nursing care activity consisted of 8 subdomains including professional practice (assessment, diagnosis, planning, intervention, evaluation, education, research, and leadership). The Importance-Performance Matrix was used to analyze the importance of and confident performance in each of the nursing subdomains. Results: Both importance and performance confidence increased as nurses’ age (p=.042 and p<.001) and clinical experience (p=.004 and p<.001). Participants scored relatively higher in importance and performance confidence in the professional practice subdomains (assessment, intervention, evaluation), but scored lower in the education and research subdomains. Conclusion To provide evidence-based nursing care for high-risk infants in neonatal intensive care units, educational interventions should be developed to support nurses based on the findings of the research.

Acquired hemophilia is a rare disorder associated with fatal bleeding caused by the development of autoantibodies against factor VIII. Here, we report the cases of two young women with acquired hemophilia who presented with massive internal hemorrhage and purpura. Both patients were successfully treated with combination therapy including factor VIII or factor VIII bypassing agent, immunosuppressants, and therapeutic plasmapheresis.

The aim of this report was to discuss the development and content of a guide on clinical performance and basic clinical skills for medical students. We published the first edition of this guide in 2010 and will publish the second edition in 2016. Initially, we took a survey on important clinical presentations and fundamental clinical and technical skills in 41 medical schools in Korea. Ultimately, we chose 80 core clinical presentations and 56 clinical skills. In the guide to basic clinical skills, we described the physical examination and technical skills according to the preprocedural preparation, procedure, and postprocedural process. In the guide on clinical performance, we reviewed patient encounters-from history taking and the physical examination to patient education. We included communication skills, principles of patient safety, and clinical reasoning schemes into the guides. In total, 43 academic faculty members helped develop the basic clinical skills guide, 75 participated in establishing the clinical performance guide, and 16 advisors from 14 medical specialty societies contributed to the guide. These guides can help medical students approach patients holistically and safely.

In this study, we developed the disc-type bio-cartilage reconstruction strategies for transplantable hyaline cartilage for reconstructive surgery using 3D-cell sheet culture of human bone marrow stromal cells and human costal chondrocytes. We compared chondrogenesis efficiency between different chondrogenic-induction methods such as micromass culture, pellet culture, and 3D-cell sheet culture. Among them, the 3D-cell sheet culture resulted in the best chondrogenesis with the disc-type bio-cartilage (>12 mm diameter in size) in vitro, but sometimes spontaneous curling and contraction of 3D-cell sheet culture resulted in the formation of bead-type cartilage, which was prevented by type I collagen coating or by culturing on amniotic membrane. Previously, it was reported that tissue-engineered cartilage reconstructed in vitro does not maintain its cartilage phenotype after transplantation but tends to transform to other tissue type such as bone or connective tissue. However, the disc-type bio-cartilage of 3D-cell sheet culture maintained its hyaline cartilage phenotype even after exposure to the osteogenic-induction condition in vitro for 3 weeks or after the transplantation for 4 weeks in mouse subcutaneous. Collectively, the disc-type bio-cartilage with 12 mm diameter can be reproducibly reconstructed by the 3D-cell sheet culture, whose hyaline cartilage phenotype and shape can be maintained under the osteogenic-induction condition as well as after the transplantation. This disc-type bio-cartilage can be proposed for the application to reconstructive surgery and repair of disc-type cartilage such as mandibular cartilage and digits.

Background: The human lung serves as a niche for a unique and dynamic bacterial community related to the development and aggravation of multiple respiratory diseases. Therefore, identifying the microbiome status is crucial to maintaining the microecological balance and maximizing the therapeutic effect on lung diseases. Therefore, we investigated the histological type-based differences in the lung microbiomes of patients with lung cancer. Methods: We performed 16S rRNA sequencing to evaluate the respiratory tract microbiome present in bronchoalveolar lavage fluid. Patients with non-small cell lung cancer were stratified based on two main subtypes of lung cancer: adenocarcinoma and squamous cell carcinoma (SqCC). Results: Among the 84 patients analyzed, 64 (76.2%) had adenocarcinoma, and 20 (23.8%) had SqCC. The α- and β-diversities showed significant differences between the two groups (p=0.004 for Chao1, p=0.001 for Simpson index, and p=0.011 for PERMANOVA). Actinomyces graevenitzii was dominant in the SqCC group (linear discriminant analysis [LDA] score, 2.46); the populations of Haemophilus parainfluenza (LDA score, 4.08), Neisseria subflava (LDA score, 4.07), Porphyromonas endodontalis (LDA score, 3.88), and Fusobacterium nucleatum (LDA score, 3.72) were significantly higher in the adenocarcinoma group. Conclusion Microbiome diversity is crucial for maintaining homeostasis in the lung environment, and dysbiosis may be related to the development and prognosis of lung cancer. The mortality rate was high, and the microbiome was not diverse in SqCC. Further large-scale studies are required to investigate the role of the microbiome in the development of different lung cancer types.

Pruritus (itching) is classically defined as an unpleasant cutaneous sensation that leads to scratching behavior. Although the scientific criteria of classification for pruritic diseases are not clear, it can be divided as acute or chronic by duration of symptoms. In this study, we investigated whether skin injury caused by chemical (contact hypersensitivity, CHS) or physical (skin-scratching stimulation, SSS) stimuli causes initial pruritus and analyzed gene expression profiles systemically to determine how changes in skin gene expression in the affected area are related to itching. In both CHS and SSS, we ranked the Gene Ontology Biological Process terms that are generally associated with changes. The factors associated with upregulation were keratinization, inflammatory response and neutrophil chemotaxis. The Kyoto Encyclopedia of Genes and Genomes pathway shows the difference of immune system, cell growth and death, signaling molecules and interactions, and signal transduction pathways. Il1a , Il1b and Il22 were upregulated in the CHS, and Tnf, Tnfrsf1b, Il1b, Il1r1 and Il6 were upregulated in the SSS. Trpc1 channel genes were observed in representative itching-related candidate genes. By comparing and analyzing RNA-sequencing data obtained from the skin tissue of each animal model in these characteristic stages, it is possible to find useful diagnostic markers for the treatment of itching, to diagnose itching causes and to apply customized treatment.
