Impact of artificial accelerated ageing of PVC surfaces and surface degradation on disinfectant efficacy.

Background: Standardized efficacy surface tests for disinfectants are performed on pristine surfaces. There is a growing interest in understanding the impact of surface ageing on disinfectant activity, owing for example to the increased usage of ultraviolet (UV) radiation and oxidative chemistries for surface decontamination. This acknowledges that general surface 'wear and tear' following UV radiation and oxidative biocide exposure may impact biocidal product efficacy.

NOAC Therapy According to CHA2DS2-VASc Without Atrial Fibrillation: A Systematic Review.

According to Quality-Adjusted Life Expectancy, novel oral anticoagulant therapy is preferred when the stroke risk is higher than 0.9% per year. CHA2DS2-VASc is a tool to select those patients at high risk for stroke due to atherosclerosis and atrial cardiopathy, who could benefit from anticoagulation even in sinus rhythm.

Freeze/Thaw Resistance of Mortar with Recycled Tyre Waste at Varying Particle Sizes.

There is a growing concern for finding alternative solutions to construction materials in order to minimise their environmental impact as well as enhancing their service life. This study investigated the durability of cementitious mortars prepared by replacing fine aggregate (sand) with recycled tyre shreds and crumbs, aiming at providing an alternative outlet to tyre waste disposal. Tyre shreds obtained at different particle sizes, from fibres of 0.

Continuous Cold Flow Device Following Total Knee Arthroplasty: Myths and Reality.

: To assess the effect of continuous cold flow (CCF) therapy on pain reduction, opioid consumption, fast recovery, less perioperative bleeding and patient satisfaction in patients undergoing a total knee arthroplasty. : Patients affected by knee osteoarthritis between September 2020 and February 2022 were enrolled in this case-control study. Patients were randomly divided into two groups ( = 50, each): the study group received postoperative CCF therapy while the control group was treated by cold pack (gel ice).
