Background: Various strategies are being explored to improve outcomes in advanced ovarian cancer. This study evaluated the survival outcomes of a sequential treatment strategy comprising dose-dense weekly chemotherapy, selective adjuvant radiotherapy, and poly(ADP-ribose) polymerase (PARP) inhibitor maintenance following primary debulking surgery. Methods: We retrospectively reviewed 12 patients with newly diagnosed advanced high-grade serous ovarian cancer (HGSOC) who underwent a sequential treatment strategy (debulking surgery followed by dose-dense chemotherapy, selective adjuvant radiotherapy, and PARP inhibitor maintenance) at Kosin University Gospel Hospital between December 2019 and March 2023. Survival outcomes were analyzed using the Kaplan-Meier method, and treatment-related adverse effects were evaluated. Results: All 12 patients achieved complete remission after the sequential treatment strategy. At the cutoff date (June 20, 2025), all patients were alive, with a median follow-up duration of 48.1 months (range, 28.7–66.5 months). The median progression-free survival (PFS) was 43.8 months. Acute toxicities, including bone marrow suppression and alopecia, were transient and manageable. Peripheral neuropathy and extremity edema were observed as persistent late toxicities. Conclusions This study highlights promising outcomes with a multimodal sequential treatment strategy in newly diagnosed advanced HGSOC. All patients remained alive at the time of analysis, and the median PFS reached 43.8 months, suggesting a potential benefit of this sequential approach compared with conventional treatment strategies. Prospective studies are warranted to validate these findings.

Bowel preparation is a key determinant of colonoscopy quality; however, inadequate cleansing remains common among patients with overlapping clinical and logistical barriers. In routine practice, preparation failure may prolong procedures, reduce diagnostic confidence, and necessitate early repeat colonoscopy. We review major society guidelines and selected studies addressing bowel preparation in inflammatory bowel disease (IBD), chronic kidney disease (CKD), older adults, chronic constipation, and hospitalized patients. Across these settings, the most consistently supported measures include split-dose administration, completion of the final dose close to the time of colonoscopy in accordance with local fasting and sedation policies, and structured patient instructions reinforced through follow-up communication. A standardized assessment of preparation quality is recommended to support quality improvement and appropriate follow-up. Risk stratification can help identify patients who may benefit from intensified preparation pathways, including those with prior inadequate preparation, severe constipation, frailty, or inpatient status. Safety considerations are particularly important in CKD, in which oral sodium phosphate should be avoided and magnesium-containing agents used cautiously; polyethylene glycol-based solutions are generally preferred. In IBD, regimen selection should also consider endoscopic interpretability because sodium phosphate preparations have been associated with preparation-related mucosal abnormalities that may confound the assessment of subtle inflammatory findings. Among hospitalized patients, system-level barriers often predominate, and protocolized pathways may improve workflow and patient comfort while maintaining cleansing effectiveness. We propose a practical, risk-stratified approach to regimen selection, timing, rescue strategies, and safety monitoring that can be implemented in high-volume clinical practice.

Background: Despite advancements in laboratory animal facility management, pinworm infections remain a persistent issue in immunodeficient mouse colonies. Rapid diagnosis and treatment are crucial to mitigating potential scientific and economic consequences. Effective control requires both the administration of anthelmintic agents and rigorous environmental decontamination. However, the safety and efficacy of these treatments in genetically modified mouse models remains uncertain.Case presentation Aspiculuris tetraptera infestation was identified in multiple immunodeficient mouse models housed in a laboratory facility. Diagnosis was confirmed through fecal flotation for egg detection and necropsy for adult worm examination in the large intestines. Mice received three subcutaneous ivermectin injections at two-week intervals, coupled with environmental decontamination using ivermectin spray for four consecutive weeks. Following treatment, all colonies tested negative for A. tetraptera without any mortality. Conclusions A combination of subcutaneous ivermectin injection and environmental spray application effectively eradicated A. tetraptera infestation in immunodeficient mouse colonies. The treatment protocol led to the complete elimination of eggs and adult worms, offering a practical strategy for managing pinworm infections in genetically modified mouse models. Limitations include the small sample size, and the lack of a comprehensive evaluation of physiological and metabolic safety in immunodeficient mice. Further validation will be required to confirm the broader applicability of this approach.

BACKGROUND/OBJECTIVES: Dietary supplement use is common among breast cancer survivors, but studies on Asian populations remain limited. This study investigated dietary supplement use among Korean breast cancer survivors, distinguishing between vitamin/ mineral (VM) and non-vitaminon-mineral (NVNM) supplements. SUBJECTS/METHODS: This cross-sectional study included 1,136 stage I–III breast cancer survivors from 12 Korean hospitals, who survived more than 6 mon post-surgery. The participants completed a questionnaire on post-diagnostic dietary supplement use. Stepwise logistic regression was applied, calculating odds ratios (ORs) and 95% confidence intervals (CIs) to identify the demographic and clinical factors associated with VM and NVNM use. RESULTS: Seventy percent of survivors reported supplement use, with 25% using a single product. The most common VM supplements were multivitamins/minerals, vitamin D, and vitamin C, while the most common NVNM supplements included omega-3 fatty acids, probiotics, and ginseng. Survivors with higher education and greater physical activity were more likely to use VM supplements (ORs [95% CIs], 2.74 [1.76–4.25] for college graduates or above vs. middle school or below; 1.38 [1.02–1.88] for the most active group vs. the least active group). NVNM use was associated with higher education, greater physical activity levels, and a history of smoking (ORs [95% CIs], 2.29 [1.46–3.58] for college graduates or above vs. middle school or below; 1.52 [1.13–2.06] for the most active group vs. the least active group; 2.00 [1.23–3.25] for ever smokers vs. never smokers). Survivors who had undergone chemotherapy were also more likely to use NVNM supplements than those who had not (OR [95% CI], 1.37 [1.02–1.84]). CONCLUSION Seventy percent of Korean breast cancer survivors used dietary supplements in this study. VM use was associated with higher education and physical activity, while higher NVNM use was associated with higher education, greater physical activity, a history of smoking, and chemotherapy.

BACKGROUND/OBJECTIVES: This study evaluated the anti-adipogenic effects of skim milk hydrolysate with alcalase and prozyme (SMH-AP) in 3T3-L1 cells and identified its bioactive peptides.MATERIALS/METHODS: After adipogenic differentiation, 3T3-L1 adipocytes were treated with SMH-AP. RESULTS: SMH-AP, produced via sequential hydrolysis with Alcalase and Prozyme, significantly inhibited lipid accumulation and modulated adipogenic and lipogenic biomarkers. It downregulated CCAAT/enhancer-binding protein (C/EBP) β, C/EBPα, peroxisome proliferator-activated receptor gamma, and sterol regulatory element-binding protein (SREBP) 1c, while upregulating Krüppel-like factor 2. SMH-AP suppressed the cholesterogenic markers (SREBP2 and 3-hydroxy-3-methylglutaryl-coenzyme A reductase) and activated AMP-activated protein kinase alpha, which phosphorylated acetyl-CoA carboxylase and activated hormone-sensitive lipase.Molecular analysis confirmed extensive proteolysis into small, cell-permeable peptides (~330 Da). Liquid chromatography–mass spectrometry/mass spectrometry identified Ala–Val–Pro– Tyr–Pro and Gly–Leu–Pro–Gln–Glu as major bioactive peptides. CONCLUSION These findings suggest that SMH-AP may serve as a promising functional food ingredient for preventing obesity.

Background: A systematic evaluation of potential living liver donors is essential to ensure donor safety and optimize recipient outcomes in living donor liver transplantation (LDLT). This study aimed to assess donor acceptance rates and reasons for disqualification among individuals evaluated for LDLT at a high-volume transplant center over a one-year period. Methods: We retrospectively reviewed 1,087 potential living liver donors who presented for LDLT evaluation in 2023. Of these, 991 candidates advanced beyond the initial screening (Stage 1) and underwent comprehensive clinical, imaging, and pathological assessments (Stages 2 and 3). Candidates who discontinued after Stage 1 were excluded due to the absence of documented reasons for non-progression. Results: Among the 991 candidates who proceeded beyond initial screening, 473 (47.7%) completed the full donor evaluation, of whom 466 were judged to be suitable donors. Among suitable donors, 384 (82.4%) proceeded to donor hepatectomy, whereas 82 did not, primarily due to recipient-related factors such as clinical deterioration or withdrawal of consent. Donor ineligibility was determined in 422 candidates (42.6%), most commonly due to inadequate remnant liver volume (52.8%), hepatic steatosis (20.6%), and insufficient graft size (10.2%). Among candidates undergoing Stage 2 evaluation, 162 (16.3%) failed to meet steatosis criteria; 126 were excluded solely for steatosis and advised weight reduction, and 39 subsequently became eligible and successfully donated. Conclusion In this high-volume LDLT center, donor disqualification was primarily driven by remnant liver volume and hepatic steatosis. Targeted interventions such as weight reduction enabled successful donation in a subset of initially ineligible candidates, underscoring the importance of individualized donor evaluation and pre-donation optimization.

Purpose: Due to its rarity, treatment guidelines for appendiceal cancer have traditionally followed those established for colorectal cancer, despite showing distinct histologic and clinical features. This study aimed to compare the clinicopathologic characteristics and long-term oncologic outcomes of appendiceal cancer with those of right-sided colon cancers. Methods: We retrospectively reviewed the records of patients with stage I–III appendiceal, cecal, or ascending colon cancer who underwent curative resection between 2010 and 2020 at our center. A 1:3:3 exact matching for age, sex, TNM stage, and adjuvant chemotherapy was performed. Survival outcomes were analyzed using the Kaplan-Meier and Cox regression methods. Results: Overall, 245 patients with appendiceal cancer (n = 35), ascending colon cancer (n = 105), and cecal cancer (n = 105) were analyzed. Appendiceal cancer exhibited a higher proportion of T4 tumors and fewer harvested lymph nodes compared with ascending or cecal cancers. The mean follow-up duration was 9.5 years. The 5- and 10-year overall survival rates were lower in appendiceal cancer (66.2% and 52.9%) than in ascending (91.2% and 78.4%) or cecal cancer (88.5% and 78.3%). Similarly, the 10-year disease-free survival rate was lower in appendiceal cancer (59.2%) compared with ascending (83.1%) and cecal cancers (78.4%). Cox regression analysis identified age (≥65 years), perforation, nodal metastasis, and lymphovascular invasion as independent predictors of poor prognosis. Conclusion Appendiceal cancer exhibited significantly worse long-term survival compared to cecal or ascending colon cancer. Tumor perforation, nodal metastasis, and lymphovascular invasion were adverse prognostic factors for overall and disease-free survival.

Phyllodes tumors are rare biphasic fibroepithelial breast neoplasms classified as benign, borderline, or malignant. Despite their rarity, malignant variants carry higher risks of recurrence and metastasis. This review synthesizes current evidence on their clinical, histopathological, and molecular characteristics, including treatment strategies and prognostic factors, emphasizing tailored management. We performed a comprehensive literature review to summarize knowledge on clinical presentation, imaging, histopathological features, surgical treatment, adjuvant therapy, and outcomes. Recent genomic and molecular research was also evaluated to identify future directions. Persistent challenges include a lack of consensus on optimal surgical margins, adjuvant radiotherapy, and follow-up protocols, highlighting the need for larger, high-quality studies. Advances in molecular profiling suggest potential for targeted therapies, especially in aggressive or metastatic cases. Due to clinical heterogeneity and the limited accuracy of core biopsies, definitive grading based on surgical histopathology remains essential for treatment planning. This review offers an updated perspective on phyllodes tumor management, identifies critical gaps, and suggests priorities for future research.

Purpose: We investigated the antiadhesive effects of lidocaine, methylene blue, and atorvastatin, with a focus on preventing remote adhesions in a rat model of postoperative adhesions. Methods: Models were assigned to either the control group (saline infusion only) or treatment groups (group L, lidocaine;group M, methylene blue; or group S, atorvastatin). Adhesions were induced by intestinal or abdominal wall injuries. The rats were sacrificed 2 weeks after surgery. Results: The number of remote adhesions was markedly lower in groups L, M, and S than in the control group. The macroscopic adhesion score was substantially lower in groups L, M, and S than in the control group. Acute and chronic inflammation, as well as fibrosis scores, were also markedly lower in groups L, M, and S than in the control group. IL-1βlevels were considerably reduced in groups L, M, and S at 2 hours after surgery and remained substantially lower in group S at 48 hours. IL-6 levels were markedly reduced in groups M and S at 2 hours and in all treatment groups at 48 hours than in the control group. Conclusion Intraperitoneal administration of lidocaine, methylene blue, and atorvastatin effectively reduced remote adhesion formation, macroscopic and microscopic adhesion scores, and inflammatory cytokine levels in a rat adhesion model.

Purpose: Although host body composition, nutritional and systemic inflammatory status have been suggested to have an impact on prognosis in patients with colorectal cancer (CRC), their impact on patients with stage IV CRC remains unclear.This study investigated the prognostic effects of those parameters in patients initially diagnosed with stage IV CRC who underwent surgery. Methods: Patients with stage IV CRC who underwent surgery were selected. Preoperative computed tomography images were evaluated for skeletal muscle index, skeletal muscle density (SMD), visceral fat area (VFA), and subcutaneous fat area (SFA). For nutritional status and systemic inflammation, prognostic nutritional index (PNI), neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR) were used. The Cox proportional hazard model was used to evaluate the prognostic significance of progression-free survival (PFS) after adjustment for the other covariates in the model. Results: Data of 134 patients with stage IV CRC who underwent surgery between January 2005 and February 2014 were included. SMD, VFA, SFA, PNI, NLR, LMR, and PLR were associated with PFS in the univariable analysis. In the multivariable analysis, SFA (hazard ratio [HR], 0.612; 95% confidence interval [CI], 0.389–0.961; P = 0.033), and PNI (HR, 0.536; 95% CI, 0.345–0.832; P = 0.005) were identified to be independent prognostic factors for PFS. Conclusion SFA and PNI both demonstrated prognostic significance in patients with stage IV CRC. Accordingly, we believe further studies are warranted to determine whether incorporating these factors can aid in surgical decision-making for stage IV CRC patients.
