    Intraperitoneal surgical mesh implantation is required for laparoscopic ventral hernia repair. Composite meshes are well known in animal models and human practice. The aim of our study is to compare the biological behaviour of two different textured siliconecovered polypropylene meshes. Transmural abdominal wall defect was created in 40 rabbits and treated as follows: In 20 animals a polypropylene mesh with a laminar silicone covering (LSPP) and in the rest a macroporous textured mesh knitted of silicone-impregnated polypropylene filaments (MSPP) was applied. One and three weeks after implantation we evaluated the intraperitoneal adhesion formation of the mesh macroscopically, histologically and immunohistochemically to detect the reactive cells, especially inflammatory, endothelial and mesothelial cells, as well as their proliferative activity, and with Scanning Electron microscopy to visualize the surface of the meshes. The adhesion formation caused by the composites showed no statistical difference after one week although in the three weeks old samples the LSPP adhesion was significantly weaker than that of MSPP. As complications, serome formation in both groups, fistulas, abscesses, and sc. haematoma in the LSPP group were found. Only in MSPP containing tissues was the decrease of Ki-67 positive proliferating cells significant. A significant increase in VEGF expressing cells was observed only in MSPP containing three week old samples, suggesting better regulation of vascular growth in tissues surrounding the implants. In one week old specimens we observed an irregular proliferation of cytokeratin containing mesothelial cells in both group. The intraperitoneal surface of MSPP mesh was covered with neoperitoneum, while it was not regurarly seen on LSPP mesh after three week.

    Background: Wearable devices such as smart watches already collect and monitor our data on physical activity, sleep time, and even vital signs. One of the groups where this monitoring can be most useful are older people, firstly due to its growing weight in the population and secondly due to its greater fragility and vulnerability. Objective: The purpose of this review is to know the scope in the scientific literature in relation to the use and impact of portable devices with artificial intelligence support in the care of elderly people. Methods: A scoping review was conducted on PubMed, including English articles published between 2017 and 2023, following Joanna Briggs Institute (JBI) guidelines and the Prisma ScR checklist. A narrative synthesis of the included articles was performed. Results: A total of 141 articles addressing the research topic were found, of which 25 met the inclusion criteria. The countries with the most publications are the United States (n=6) followed by Korea and Spain (n=4) each. The most investigated geriatric syndrome was falls (72%). None of the publications considered the ethical implications of using these devices. Only 2 papers were elaborated by nurses. Thirteen clinical trials reported high positive impacts, 10 studies reported minor positive impacts. Conclusions: Most studies demonstrate the effectiveness of this technology for monitoring and its usefulness in elderly care. Falls prevention and detection are the most researched areas, greater ethical analysis of the impact of these devices and nursing involving in research is necessary.
