Article Abstract

Introduction: Enfortumab vedotin (EV) and Erdafitinib are effective therapeutic drugs for bladder cancer patients following post-chemotherapy and immunotherapy. This study assessed adverse drug reactions (ADRs) from both drugs, comparing their safety profiles to guide clinical use.

Methods: A retrospective descriptive analysis was conducted on ADR reports for EV and Erdafitinib from the World Health Organization (WHO)-VigiAccess database. Data on patient demographics, system organ classes (SOCs), global patient regions, symptoms, and ADRs frequencies were analyzed and compared.

Results: As of 2024, 3,438 ADR reports were identified (2,257 for EV and 1,181 for Erdafitinib). The number of adverse reaction reports for EV is significantly higher than that for Erdafitinib. Among them, the SOC with the most adverse signals is gastrointestinal disorders, with the top five reports being nausea, gastrointestinal disorders, dry mouth, abdominal pain, and diarrhea. The top five reported adverse events (AEs) for EV are as follows: skin and subcutaneous tissue disorders (20.70%), general disorders and administration site conditions (14.23%), nervous system disorders (11.12%), gastrointestinal disorders (7.78%), and metabolism and nutrition disorders (6.47%). In contrast, the top five AEs for Erdafitinib are: general disorders and administration site conditions (25.36%), skin and subcutaneous tissue disorders (10.94%), gastrointestinal disorders (10.19%), eye disorders (9.21%), and injury poisoning and procedural complications (7.31%).

Conclusion: Our study identified and compared potential and novel ADRs between EV and Erdafitinib, providing key insights into their safety profiles and highlighting the need for personalized treatment strategies based on individual patient risk factors.

Peptide-based drugs possess several advantages, including high specificity, low immunogenicity, minimal accumulation, and fewer drug-drug interactions, making them a novel and efficient therapeutic class for various diseases. In recent years, peptide-based drugs have shown great potential and broad application prospects in the treatment of oral infectious diseases, tissue injury and repair, tumors, and complex oral mucosal disorders, acting either through direct mechanisms or indirect modulation. Oral administration remains the preferred route due to its non-invasive, painless nature and ease of management; however, gastrointestinal pH can inactivate or even degrade peptide drugs.

Objectives: Recent evidence suggests that the gut may be a primary site of metformin action. However, studies on the effects of metformin on gut microbiota remain limited, and its impact on gut microbial metabolites such as short-/medium-chain fatty acids is unclear. This study aims to investigate the effects of metformin on gut microbiota, short-/medium-chain fatty acids, and associated metabolic benefits in high-fat diet rats.

Kommerell's diverticulum (KD) combined with a right-sided aortic arch (RAA) and an aberrant left subclavian artery (ALSA) is a rare congenital vascular anomaly causing significant compressive dysphagia. Treatment options, including open surgery, thoracic endovascular aortic repair and hybrid approaches, are debated due to anatomical complexities. We report a 48-year-old female with dysphagia from symptomatic KD, RAA and ALSA, clearly delineated by preoperative computed tomography angiography.

Background: Cancer of unknown primary (CUP) is a challenging malignancy characterized by metastatic tumors with an unidentified primary site, even after extensive pathological and radiographic evaluation. Recent advancements in gene expression profiling and comprehensive genomic profiling (CGP) using next-generation sequencing (NGS) have enabled the identification of potential tissue origins, thereby facilitating personalized treatment strategies. Although most cases of CUP present as adenocarcinomas or poorly differentiated tumors, the treatment remains largely empirical, with limited success from molecularly tailored therapies.

Objectives: To study the impact of SURF4 expression level on long-term prognosis of gastric cancer (GC) and biological behaviors of GC cells.

Methods: SURF4 expression level in GC and its association with long-term patient prognosis were analyzed using publicly available databases and in 155 GC patients with low and high SURF4 expressions detected immunohistochemically. The Cox proportional hazard model and Kaplan-Meier survival curves were used to analyze independent prognostic predictors of GC and the 5-year survival rate of the patients with different SURF4 expression levels.
