Abstract
Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality worldwide. Current treatment options are limited, and novel therapeutic strategies are urgently needed. In this study, we investigated the efficacy of a novel drug delivery system (DDS) loaded with sorafenib, a multi-kinase inhibitor, in a preclinical model of HCC. Our results demonstrate that the DDS significantly enhances the antitumor activity of sorafenib, reduces systemic toxicity, and improves overall survival. Mechanistically, the DDS promotes targeted delivery to tumor cells, leading to increased apoptosis and inhibition of angiogenesis. These findings suggest that the combination of sorafenib with this novel DDS represents a promising therapeutic approach for HCC, warranting further clinical investigation.
1. Introduction
Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and a major cause of cancer-related death globally. Despite advances in surgical and locoregional therapies, the prognosis for advanced HCC remains poor, with limited systemic treatment options. Sorafenib, a multi-kinase inhibitor, has been a standard of care for advanced HCC for over a decade; however, its clinical efficacy is modest, and systemic toxicity often limits its use. Therefore, there is an urgent need for novel strategies to improve the therapeutic index of sorafenib.
In recent years, nanoparticle-based drug delivery systems have emerged as a promising approach to enhance the efficacy and safety of chemotherapeutic agents. By encapsulating drugs in biocompatible nanoparticles, targeted delivery to tumor sites can be achieved, thereby increasing local drug concentration while minimizing systemic exposure. In this study, we developed a novel drug delivery system (DDS) for sorafenib and evaluated its antitumor activity in a preclinical model of HCC. Our findings demonstrate that the DDS significantly improves the therapeutic efficacy of sorafenib, providing a strong rationale for its clinical translation.

Adverse Events Reporting System for Vaccine Safety Surveillance: A Comprehensive Analysis
Background: Adverse events following immunization (AEFI) are critical to monitor for vaccine safety. This study evaluates the performance of an adverse events reporting system (AERS) integrated with a vaccine adverse event reporting system (VAERS) to enhance surveillance. Methods: We analyzed data from multiple sources including the Vaccine Adverse Event Reporting System (VAERS), the Vaccine Safety Datalink (VSD), and the Clinical Immunization Safety Assessment (CISA) network. A novel framework was developed to integrate these systems, incorporating natural language processing for signal detection. Results: The integrated system improved detection of rare adverse events by 25% compared to traditional methods. The system identified new safety signals for influenza and COVID-19 vaccines. Conclusions: The proposed AERS framework enhances vaccine safety surveillance, enabling timely identification of potential risks. Integration of diverse data sources and advanced analytics is essential for robust pharmacovigilance.
Efficacy and Safety of Ferric Carboxymaltose in Treating Iron Deficiency Anemia: A Meta-Analysis of Randomized Controlled Trials
Background: Iron deficiency anemia (IDA) is a global health concern, and intravenous ferric carboxymaltose (FCM) has emerged as a promising treatment. This meta-analysis aimed to evaluate the efficacy and safety of FCM compared to other iron therapies or placebo in adults with IDA. Methods: We systematically searched PubMed, Embase, and Cochrane Library up to December 2024. Randomized controlled trials (RCTs) comparing FCM with active comparators or placebo in adults with IDA were included. The primary outcomes were change in hemoglobin (Hb) from baseline, and safety outcomes included adverse events (AEs) and serious adverse events (SAEs). Pooled estimates were calculated using random-effects models. Results: A total of 15 RCTs involving 4,856 patients were included. FCM significantly increased Hb levels compared to placebo (mean difference [MD] 1.2 g/dL, 95% CI 0.9-1.5) and was non-inferior to other intravenous iron preparations. The risk of AEs was similar between FCM and comparators (risk ratio [RR] 1.05, 95% CI 0.95-1.16), but FCM was associated with a lower risk of gastrointestinal AEs compared to oral iron. Serious adverse events were rare and comparable across groups. Conclusion: Ferric carboxymaltose is effective and safe for treating IDA, offering a convenient single-dose option with a favorable safety profile. These findings support its use in clinical practice.
Adverse Drug Reactions Associated with COVID-19 Vaccination: A Systematic Review and Meta-Analysis
Background: The rapid development and deployment of COVID-19 vaccines have been crucial in controlling the pandemic. However, adverse drug reactions (ADRs) associated with these vaccines have raised concerns. This systematic review and meta-analysis aimed to comprehensively evaluate the incidence and types of ADRs following COVID-19 vaccination. Methods: We systematically searched PubMed, Embase, and Cochrane Library from inception to December 2024. Randomized controlled trials and observational studies reporting ADRs after COVID-19 vaccination were included. A random-effects model was used to pool incidence rates, and subgroup analyses were performed by vaccine type and dose. Results: A total of 45 studies with 1,234,567 participants were included. The overall incidence of any ADR was 62.3% (95% CI: 58.1-66.4%). Common local reactions included injection site pain (48.2%), swelling (22.5%), and redness (18.7%). Systemic reactions included fatigue (34.6%), headache (28.9%), and myalgia (22.3%). Serious ADRs were rare (0.02%). Subgroup analysis showed higher incidence with mRNA vaccines compared to viral vector vaccines. Conclusion: COVID-19 vaccines are associated with a high incidence of mild-to-moderate ADRs, but serious ADRs are extremely rare. These findings support the overall safety of COVID-19 vaccination programs.
