Immunotherapy that activates the host immune system to reverse immunosuppression has emerged as a new generation of cancer treatment in both preclinical studies and clinical trials. Although immunotherapy has shown significant achievements in the treatment of various cancers, it faces challenges that limit its further evolution such as poor permeation and modest responsiveness. The development of nanoparticle drug delivery system has provided an opportunity to overcome these drawbacks and to achieve optimized immunotherapy. Based on the research of our group, we here introduce the new strategies being employed using nanoscale intelligent drug delivery systems to enhance the effects of cancer immunotherapy. We also provide a perspective on the further possible application of nanoparticles in more effective antitumor immunotherapy.

The pursuit of linear dosage in pharmacy: reservoir-based drug delivery systems from macro to micro scale.
Expert Opin Drug Deliv
January 2025
Vladimir Zelman Center for Neurobiology and Brain Rehabilitation, Moscow, Russia.
Introduction: The pursuit of linear dosage in pharmacy is essential for achieving consistent therapeutic release and enhancing patient compliance. This review provides a comprehensive summary of zero-order drug delivery systems, with a particular focus on reservoir-based systems emanated from different microfabrication technologies.
Areas Covered: The consideration of recent advances in drug delivery systems is given to encompass the key areas including the importance of achieving a constant drug release rate for therapeutic applications.
Characterization of lamotrigine disposition changes during and after pregnancy in women with epilepsy.
Pharmacotherapy
January 2025
Department of Experimental and Clinical Pharmacology, University of Minnesota, Minneapolis, Minnesota, USA.
Background: Lamotrigine clearance can change drastically in pregnant women with epilepsy (PWWE) making it difficult to assess the need for dosing adjustments. Our objective was to characterize lamotrigine pharmacokinetics in PWWE during pregnancy and postpartum along with a control group of nonpregnant women with epilepsy (NPWWE).
Methods: The Maternal Outcomes and Neurodevelopmental Effects of Antiepileptic Drugs (MONEAD) study was a prospective, observational, 20 site, cohort study conducted in the United States (December 2012 and February 2016).
Charge Regulation-Enhanced Type I Photosensitizer-Loaded Hydrogel Dressing for Hypoxic Bacterial Inhibition and Biofilm Elimination.
ACS Nano
January 2025
State Key Laboratory of Fine Chemicals, College of Materials Science and Engineering, Shenzhen University, Shenzhen 518055, China.
Biofilm-induced chronic bacterial infections represent a significant challenge in modern medicine due to their resistance to conventional antibiotic treatments. Although photodynamic therapy (PDT) has emerged as a promising antibiotic-free antibacterial strategy, the hypoxic condition within biofilms and the lack of an effective local drug delivery system have limited the clinical effectiveness of photosensitizer (PS) agents. Herein, we propose a type of charge regulation-enhanced type I PS-loaded hydrogel dressing for treating biofilm infection.

Syreon Research Institute, Budapest, Hungary.
Background: Non-adherence to medication remains a persistent and significant challenge, with profound implications for patient outcomes and the long-term sustainability of healthcare systems. Two decades ago, the World Health Organization (WHO) dedicated its seminal report to adherence to long-term therapies, catalysing notable changes that advanced both research and practice in medication adherence. The aim of this paper was to identify the most important progress made over the last 2 decades in medication adherence management and to initiate a discussion on future objectives, suggesting priority targets for the next 20 years.

Front Microbiol
December 2024
Department of Laboratory Medicine, Guangdong Provincial Hospital of Chinese Medicine, Zhuhai, China.
Background: Previous microbiological investigations have demonstrated a significant correlation between complex (CKC) infection and mastitis. Recent studies have confirmed the existence of the CKC, with () identified as the primary infectious agent. Examining the incidence of CKC in cases of severe non-lactational mastitis, alongside the clinical characteristics of infected patients, as well as evaluating the drug sensitivity testing protocols for CKC, can provide a more robust foundation for the diagnosis and treatment of CKC infections.
