Over the past two decades, experimental and clinical evidence has established the interleukin-23 (IL-23)/interleukin-17 (IL-17) axis as a key mediator of psoriatic inflammation. IL-23, primarily derived from activated dendritic cells, supports the survival and pathogenic function of type 17 immune cells, which subsequently release IL-17A, IL-17F, and IL-22 to promote keratinocyte activation and recruit inflammatory leukocytes. These mechanistic insights have directly translated into the development of highly effective biologic therapies targeting IL-17 or IL-23, substantially improving the management of psoriasis. Beyond injectable biologics, growing efforts to overcome limitations related to long-term adherence, cost, and accessibility have accelerated the development of non-injectable therapeutic approaches. Oral and topical small-molecule agents, including selective tyrosine kinase 2 (TYK2) inhibitors and IL-23 receptor antagonists, are now broadening the therapeutic options. At the same time, progress in molecular engineering, artificial intelligence–guided protein design, and spatial multi-omic technologies are refining therapeutic discovery and enabling more precise targeting of pathogenic immune circuits. In this review, we outline the current understanding of the IL-23/IL-17 pathway in psoriasis pathogenesis and provide a critical overview of approved and emerging therapies directed at this pathway. We also address key biological and translational challenges, including tissue-specific cytokine functions, interspecies differences, and long-term safety considerations, and discuss how these factors may inform future strategies for precision immunotherapy in psoriasis.

Purpose: Limited treatment options exist for patients with metastatic castration-resistant prostate cancer (mCRPC) after the failure of taxane-based chemotherapy and novel hormonal therapy. Here, we report the safety and efficacy of ifosfamide and mesna in patients with mCRPC after the failure of taxane-based chemotherapy and novel hormonal therapy (NCT06236789). Materials and Methods: Patients with histologically confirmed prostate cancer who had failed taxane-based chemotherapy and novel hormonal therapy received ifosfamide 2,500 mg/m2 and mesna 1,500 mg/m2 on days 1–3, repeated every 21 days. Safety, objective response rate, disease control rate, reduction in serum prostate-specific antigen (PSA) concentration by >50% (PSA50) or >90% (PSA90), radiographic progression-free survival (rPFS), and overall survival (OS) were analyzed. Results: A total of 47 patients with mCRPC were included in the study. The median number of lines of treatment was 5 (range, 3 to 7). All patients were previously administered docetaxel and novel hormonal therapies including abiraterone (51.1%) and/or enzalutamide (61.7%). Thirty-eight patients (80.9%) were administered cabazitaxel. The objective response and disease control rates were 21.3% and 80.9%, respectively. PSA50 and PSA90 were achieved in 31.9% and 10.6%, respectively. During a median follow-up duration of 54.3 months, rPFS and OS were 5.0 and 9.0 months, respectively. All the patients experienced treatment-related adverse events of any grades; however, no new safety signs were detected. Genomic biomarker analysis revealed that alterations in the TP53 pathway were associated with inferior rPFS and OS. Conclusion Ifosfamide and mesna showed appreciable efficacy and manageable safety profiles in heavily treated patients with mCRPC.

Reference management software (RMS) represents a cornerstone of modern academic writing and publishing. For decades, programs such as EndNote, Zotero, and Mendeley have played central roles in facilitating citation organization, bibliography formatting, and collaborative scholarship. Although each platform has introduced unique innovations, persistent limitations remain, particularly with respect to usability, accessibility, and accuracy. In parallel, the rise of generative artificial intelligence has introduced an unprecedented challenge: the inadvertent inclusion of fabricated or incorrect references mistakenly incorporated into manuscripts. This phenomenon has exposed a critical limitation of traditional RMS platforms, namely their inability to verify reference authenticity. Against this backdrop, new solutions have emerged. One such example is CiteWell (https://citewell.org/), an artificial intelligence (AI)-era RMS that introduces several notable innovations, including PubMed-integrated verification, an intuitive interface for new users, customizable journal-specific styles, and multilingual accessibility. This review provides a comprehensive historical overview of RMS, evaluates the strengths and weaknesses of major platforms, and positions emerging AI-based tools as a new paradigm that combines traditional reference management with essential safeguards for contemporary academic challenges.

The fundamental principles for treating ankle fractures, as with other intra-articular fractures, are anatomical reduction and stable internal fixation. Despite successful reduction, between 14% and 40% of patients continue to experience persistent pain or unsatisfactory functional outcomes. Furthermore, approximately 1% of patients progress to post-traumatic arthritis, necessitating further surgical intervention. Ankle fractures are frequently accompanied by intra-articular injuries, including osteochondral lesions, ligament tears, and syndesmosis injuries. Arthroscopy is becoming increasingly prevalent in managing acute ankle fractures by assessing intra-articular damage and facilitating accurate reduction. This review examined the role and indications for arthroscopy in ankle fractures, particularly emphasizing its benefits in diagnosing and managing associated injuries, including osteochondral lesions, syndesmosis, and deltoid ligament injuries. Furthermore, arthroscopy facilitates fracture reduction, offering a minimally invasive approach with a shorter recovery period and enhanced visualization. Its use extends to pediatric fractures and complex cases such as Maisonneuve and calcaneal fractures, potentially improving outcomes while minimizing complications. Understanding the evolving indications and benefits of arthroscopy for ankle fractures can lead to improved clinical outcomes and reduced complications.

Purpose: The aim of this study was to compare local recurrence (LR) rates in patients with ductal carcinoma in situ (DCIS) at the surgical margins after breast-conserving surgery (BCS). Methods: This single-center, retrospective study included patients diagnosed with invasive ductal carcinoma (IDC) who underwent BCS at National Cancer Center between 2014 and 2020. Patients with DCIS at the surgical margin were eligible for inclusion. Those who did not undergo re-excision received whole-breast radiotherapy with an escalated tumor bed boost of 15 Gy in five fractions. The 5-year breast cancer recurrence rates were estimated using the Kaplan-Meier method, and prognostic factors were evaluated using univariate and multivariate Cox proportional hazards regression models. Results: Among the 235 eligible patients, 115 underwent re-excision (Re-excision + group), and 120 did not (Re-excision − group). With a median follow-up of 5.0 years (range, 3.1–6.6 years), the 5-year LR rate was 6.1% in the Re-excision + group and 5.8% in the Re-excision − group (log-rank p = 0.9). Re-excision was not significantly associated with differences in LR rates in multivariate analysis. Conclusion In cases where DCIS was present at the surgical margin after BCS, re-excision was not associated with a lower LR rate compared with dose-escalated radiotherapy.This study did not assess late radiation-related toxicities, such as breast fibrosis, which are important considerations for treatment decision-making. These findings should be interpreted with caution because of the retrospective design and limited event rate. Further prospective studies are warranted to determine optimal management strategies.
