Self-management eHealth solutions for menopause - a systematic scoping review.

OBJECTIVE: The purpose of this scoping review was to highlight the current scientific evidence on eHealth-based information tools for menopause in terms of quality, requirements and previous intervention outcomes. METHODS: We systematically searched electronic databases (Embase, CINAHL, Cochrane Library, Global Health Database [Ovid], Web of Science, ClinicalTrials.gov [NLM], LIVIVO Search Portal [ZB MED] and Google Scholar) from 1974 to March 2022 for relevant records. RESULTS: Our search yielded 1773 records, of which 28 met our inclusion criteria. Thirteen of 28 selected studies were cross-sectional with qualitative content analysis of websites about menopause; 9 studies were cohort studies examining the impact of an eHealth intervention; two studies were randomized controlled trials comparing eHealth tools with conventional ones; and four studies were non-systematic literature reviews. CONCLUSION: This scoping review highlights the potential of eHealth-based information tools for the management of menopause and shows that most eHealth-based information tools are inadequate in terms of readability and the balanced view on information. Providers of eHealth-based information tools should pay attention to a participatory design, readability, balance of content and the use of multimedia tools for information delivery to improve understanding.

Effects of shape and structure of a new 3D-printed personalized bioresorbable tracheal stent on fit and biocompatibility in a rabbit model.

To date, several types of airway stents are available to treat central airway obstructions. However, the ideal stent that can overcome anatomical, mechanical and microbiological issues is still awaited. In addition, therapeutic effect and self-elimination of these stents are desirable properties, which pose an additional challenge for development and manufacturing. We aimed to create a prototype bioresorbable tracheal stent with acceptable clinical tolerance, fit and biocompatibility, that could be tested in a rabbit model and in the future be further optimized to enable drug-elution and ensure local therapeutic effect. Twenty-one New Zealand White Rabbits received five different types of bioresorbable tracheal stents, 3D-printed from poly(D,L-lactide-co-ε-caprolactone) metacrylates. Various configurations were tested for their functionality and improved until the best performing prototype could undergo detailed in vivo assessment, regarding clinical tolerance, migration and biocompatibility. Previously tested types of 3D printed stents in our preliminary study required improvement due to several problems, mainly related to breakage, unreliable stability and/or migration within the trachea. Abandoned or refined pre-prototypes were not analyzed in a comparative way. The final best performing prototype stent (GSP2 (Group Stent Prototype 2), n = 8) allowed a transoral application mode and showed good clinical tolerance, minimal migration and acceptable biocompatibility. The good performance of stent type GSP2 was attributed to the helix-shaped surface structure, which was therefore regarded as a key-feature. This prototype stent offers the possibility for further research in a large animal model to confirm the promising data and assess other properties such as bioresorption.

Digital Light 3D Printed Bioresorbable and NIR-Responsive Devices with Photothermal and Shape-Memory Functions.

Digital light processing (DLP) 3D printing is a promising technique for the rapid manufacturing of customized medical devices with high precision. To be successfully translated to a clinical setting, challenges in the development of suitable photopolymerizable materials have yet to be overcome. Besides biocompatibility, it is often desirable for the printed devices to be biodegradable, elastic, and with a therapeutic function. Here, a multifunctional DLP printed material system based on the composite of gold nanorods and polyester copolymer is reported. The material demonstrates robust near-infrared (NIR) responsiveness, allowing rapid and stable photothermal effect leading to the time-dependent cell death. NIR light-triggerable shape transformation is demonstrated, resulting in a facilitated insertion and expansion of DLP printed stent ex vivo. The proposed strategy opens a promising avenue for the design of multifunctional therapeutic devices based on nanoparticle-polymer composites.
