Purpose: This study aimed to develop a comprehensive practical guide for enteral nutrition (EN) designed to enhance patient safety and reduce complications in Korea. Under the leadership of the Korean Society for Parenteral and Enteral Nutrition (KSPEN), the initiative sought to standardize EN procedures, improve decision-making, and promote effective multidisciplinary communication. Methods: The KSPEN EN committee identified key questions related to EN practices and organized them into seven sections such as prescribing, delivery route selection, formula preparation, administration, and quality management. Twenty-one experts, selected based on their expertise, conducted a thorough literature review to formulate evidence-based recommendations. Drafts underwent peer review both within and across disciplines, with final revisions completed by the KSPEN Guideline Committee. The guide, which will be published in three installments, addresses critical elements of EN therapy and safety protocols. Results: The practical guide recommends that EN orders include detailed elements and advocates the use of electronic medical records for communication. Standardized prescription forms and supplementary safety measures are outlined. Review frequency is adjusted according to patient condition—daily for critically ill or unstable patients and as dictated by institutional protocols for stable patients. Evidence indicates that adherence to these protocols reduces mortality, complications, and prescription errors. Conclusion The KSPEN practical guide offers a robust framework for the safe delivery of EN tailored to Korea’s healthcare context. It emphasizes standardized protocols and interdisciplinary collaboration to improve nutritional outcomes, patient safety, and operational efficiency. Rigorous implementation and monitoring of adherence are critical for its success.

Background: Although nail psoriasis is a common manifestation among patients with psoriasis, large-scale research exploring the association between nail psoriasis lesions and their intra-nail locations has not been conducted. This study is necessary to elucidate the shared pathophysiology among various phenotypes of nail psoriasis. Objective: We aimed to understand the association between nail psoriasis lesions and analyze their intra-nail locations. Methods: We obtained a total of 5,602 cropped fingernail images from 636 patients with psoriasis. We employed the Computer Vision Annotation Tool to annotate the intra-nail locations of nail psoriasis lesions. We computed χ 2 statistic to examine the relationship between nail psoriasis lesions and conducted an analysis of their intra-nail locations. Results: Based on the number of lesions, nail pitting was the most common, followed by leukonychia, with the red spots in the lunula being the rarest. We elucidated the associations between different nail psoriasis lesions, pinpointing a significant association between onycholysis and oil spots (χ 2 statistic=1,623.88), followed by onycholysis-subungual hyperkeratosis (1,607.50), and subungual hyperkeratosis-oil spots (985.76). A spatial relationship was observed between onycholysis and oil spots, with the intra-nail location of onycholysis being more distal compared to the nearest oil spots. A distribution pattern of nail psoriasis was also demonstrated, where nail matrix lesions were primarily located at the center of the nail, and nail bed lesions were predominantly located near the lateral nail folds. Conclusion This study represents a pioneering analysis of the intra-nail location of nail psoriasis lesions, revealing substantial associations and spatial relationships between different lesions.

Background: Despite various therapeutic modalities for keloids have been introduced; however, their therapeutic effects are limited. Therefore, the development of a new approach for inhibiting collagen production by scar fibroblasts is needed. Objective: To investigate the effect of electrical stimulation using a low-frequency and low-intensity alternating current on collagen and MMP-1 levels in human dermal fibroblasts. Methods: Low-frequency (20 kHz) and low-intensity (1 V/cm) electrical stimulations were applied to primary dermal fibroblasts. The production of type I procollagen and expression of matrix metalloproteinase-1 were evaluated. Transcriptomic analyses were conducted to explore the possible modes of action of electrical stimulation. Results: Electrical stimulation effectively suppressed type I procollagen production and increased MMP-1 expression. In addition, transcriptomic analyses revealed that electrical stimulation altered the gene expression associated with membrane permeability and the structure of cellular membranes. Validation using real-time polymerase chain reaction revealed that electrical stimulation significantly altered the expression of mechanosensitive ion channels (PIEZO2) and membrane-bound protein organizing caveolae (CAVIN2). Conclusion Electrical stimulation using low-frequency and low-intensity alternating currents effectively modulates extracellular matrix homeostasis by altering the cellular membrane structure and function. Our findings suggest a promising therapeutic approach for the management of keloids and hypertrophic scars.

Background: The Korean government is implementing policy to reduce medical costs and improve treatment related for human immunodeficiency virus (HIV) patients. The level of cost reduction and the benefits provided vary depending on how individuals with HIV utilize the system. This study aims to determine exact HIV prevalence by analyzing healthcare utilization patterns and examining differences in healthcare usage based on how individuals pay for their medical expenses. Materials and Methods: We analyzed National Health Insurance Service (NHIS) claims data from 2002 to 2021. From a total of 106,675 individuals with at least one HIV-related claim, 22,779 participants were selected for this study. Results: Data from Korea Disease Control and Prevention Agency annual reports indicated that 93% of HIV patients were male, while NHIS data showed 84%. In the analysis of those exempted from registration, it was found that the registration rate for female patients is notably low, with adults between the ages of 20 and 40 making up 80% of the total. The registration rate in Gangwon State was lower than Seoul. The treatment experience rate was much higher in the registered group (93.0%) than the unregistered group (4.9%). Also, there was a big difference in treatment continuity rates: 76.2% for registered individuals and 2.8% for non-registered individuals. Conclusion The exempt calculation system for health insurance improves HIV care. However, those diagnosed anonymously or with reduced medical costs may be less likely to continue HIV treatment, so a new policy is needed to ensure anonymity and treatment continuity.

Myxoinflammatory fibroblastic sarcoma (MIFS) is a rare, low-grade soft tissue neoplasm that typically arises in the extremities. A 72-yearold woman presented with recurrent masses on her left forearm. Four years prior, she underwent an excisional biopsy, diagnosed as MIFS, followed by wide excision and split-thickness skin graft coverage. Preoperative magnetic resonance imaging was conducted for the recurrent mass, revealing multiple tumors invading the flexor digitorum profundus (FDP) muscle and fascia. The tumors including most of the FDP muscle were therefore excised. The third flexor digitorum superficialis (FDS) tendon was harvested, divided in half, and connected to the second and fifth FDP tendons. The same procedure was performed for the third and fourth FDP tendons with fourth FDS tendon. An anterolateral thigh free flap was used to reconstruct the skin and soft tissue defect of the left forearm. Adjuvant radiation therapy was performed. At 12 weeks postoperatively, the patient exhibited no wound complications and achieved spontaneous partial flexion of the metacarpophalangeal and proximal interphalangeal joints.
