In vivo pharmacokinetic study and PBPK modeling: Comparison between 3D-printed nanocrystals and solid dispersions.

The solubility of drugs remains one of the most challenging aspects of formulation development. Several technologies exist to enhance the properties of poorly soluble drugs, with nanocrystal (NC) and solid dispersion (SD) technologies being among the most important. This work compared NCs and SDs under identical conditions using albendazole as a model drug and 3D printing technology as the delivery method.

Validation of a Questionnaire to Assess the Usability of and User Experience with Mobile Health Applications.

Background/objectives: The growing use of mobile health (mHealth) applications needs reliable tools to assess their usability and user experience in clinical practice to improve the digital health (eHealth) interventions and ensure engagement, as higher engagement is often linked to increased efficacy of healthcare interventions. This study aimed to validate the patient Satisfaction and Usability with APPs questionnaire (pSUAPP), a multidimensional tool designed for the comprehensive assessment of mHealth applications, particularly for the integrated follow-up of patients with chronic diseases.

Methods: A validation study was conducted between August and December 2022 with 85 participants from two hospitals in Spain, who completed the pSUAPP questionnaire, comprising 27 Likert-like items across four dimensions: first contact, registration, features and overall experience, and 1 open question.

Targeted lung cancer screening in the age of immunotherapies and targeted therapies - an economic evaluation for Australia.

Background: The cost-effectiveness of different lung cancer screening strategies has been evaluated from an Australian public health system perspective using static models. In addition, the impact of novel therapies, including immunotherapies and targeted therapies, on the cost-effectiveness of lung cancer screening has not yet been evaluated comprehensively. We evaluated the benefits, harms and cost-effectiveness of a targeted national lung screening program in Australia, accounting for the increasing uptake of novel therapies, which informed the lung cancer screening recommendations of the Australian Medical Services Advisory Committee (MSAC).

3D-Printed Plasmonic Nanocomposites: VAT Photopolymerization for Photothermal-Controlled Drug Release.

Background: Gold nanoparticles can generate heat upon exposure to radiation due to their plasmonic properties, which depend on particle size and shape. This enables precise control over the release of active substances from polymeric pharmaceutical formulations, minimizing side effects and premature release. The technology of 3D printing, especially vat photopolymerization, is valuable for integrating nanoparticles into complex formulations.

Modeling and evaluation of ivermectin release kinetics from 3D-printed tablets.

This study focused on evaluating the influence of geometric dimensions on the drug release kinetics of 3D-printed tablets. An ink based on Gelucire 50/13 was prepared to print ivermectin-loaded tablets. The ink was characterized physicochemically and tablet dissolution tests were carried out.
