Nasal care in intensive care unit patients.
Intensive & critical care nursing, 2017Co-Authors: Orhan Ozturan, Erol Senturk, Meryem Iraz, Ayşe Nur Ceylan, Kadir Idin, Remzi Dogan, Yavuz Selim YıldırımAbstract:Abstract Purpose The aim of this study was to investigate nasal hygiene in intensive care patients and improve patient care using isotonic saline nasal Spray. Material and methods In the study group, over a period of ten days saline nasal Spray was administered four times daily. Nasal treatment was not given to the control group. Each patient was examined with a flexible nasopharyngoscope before and after the treatment and a nasal culture was taken. Results In the study group, the secretion score (1- absent; 2- serosal; 3- seropurulent and 4- purulent) mean value improved from 1.9 to 1.4. In the control group, the secretion score mean value had risen from 1.7 to 3.1. At the beginning of the study, there was no difference in secretion scores between the groups, but on the tenth day a statistically significant difference was found. Conclusion The use of saline nasal Spray in this group of intensive care patients was found to be effective in achieving nasal hygiene.

On the emergence of antibacterial and antiviral copper cold Spray coatings.
Journal of biological engineering, 2021Co-Authors: Bryer C. Sousa, Matthew A. Gleason, Christopher J Massar, Danielle L CoteAbstract:In this literature review, the antipathogenic properties and contact-mediated antibacterial and antiviral performance of copper cold Spray surfaces are assessed and compared with alternative antimicrobial Materials that are able to kill and/or inactivate infectious agents via direct contact. Discussion is also provided concerning the suitability of copper cold Spray Material consolidations as biocidal and viricidal surfaces that retain long-term functionality as a preventative measure against fomite transmission of pathogenic agents and hospital-acquired infections from contaminated high-touch surfaces. Numerable alternative antimicrobial coatings and surfaces that do not rely upon the oligodynamic action of copper are detailed. Given the ongoing need for recognition of said alternative antimicrobial Materials by authoritative agencies, such as the U.S. Environmental Protection Agency, the relevant literature on non-copper-based antipathogenic coatings and surfaces are then described. Furthermore, a wide-ranging take on antipathogenic copper cold Spray coatings are provided and consideration is given to the distinctive grain-boundary mediated copper ion diffusion pathways found in optimizable, highly deformed, copper cold Spray Material consolidations that enable pathogen inactivation on surfaces from direct contact. To conclude this literature review, analysis of how copper cold Spray coatings can be employed as a preventative measure against COVID-19 was also presented in light of on-going debates surrounding SARS-CoV-2's non-primary, but non-negligible, secondary transmission pathway, and also presented in conjunction with the inevitability that future pathogens, which will be responsible for forthcoming global pandemics, may spread even more readily via fomite pathways too.

Understanding the Antipathogenic Performance of Nanostructured and Conventional Copper Cold Spray Material Consolidations and Coated Surfaces
Crystals, 2020Co-Authors: Bryer C. Sousa, Kristin L. Sundberg, Matthew A. Gleason, Danielle CoteAbstract:The role of high strain rate and severe plastic deformation, microstructure, electrochemical behavior, surface chemistry and surface roughness were characterized for two copper cold Spray Material consolidations, which were produced from conventionally gas-atomized copper powder as well as Spray-dried copper feedstock, during the course of this work. The motivation underpinning this work centers upon the development of a more robust understanding of the microstructural features and properties of the conventional copper and nanostructured copper coatings as they relate to antipathogenic contact killing and inactivation applications. Prior work has demonstrated greater antipathogenic efficacy with respect to the nanostructured coating versus the conventional coating. Thus, microstructural analysis was performed in order to establish differences between the two coatings that their respective pathogen kill rates could be attributed to. Results from advanced laser-induced projectile impact testing, X-ray diffraction, scanning electron microscopy, electron backscatter diffraction, scanning transmission microscopy, nanoindentation, energy-dispersive X-ray spectroscopy, nanoindentation, confocal microscopy, atomic force microscopy, linear polarization, X-ray photoelectron spectroscopy, electrochemical impedance spectroscopy and copper ion release assaying were performed during the course of this research.
