A quality improvement study on the reduction of central venous catheter-associated bloodstream infections by use of self-disinfecting venous access c…

2020

Background Contamination of the catheter hub is an important source of central line-associated bloodstream infections (CLABSI); catheter hub caps incorporating a 70% isopropyl alcohol aim are designed to reduce contamination and hence CLABSI rates. Supporting data in high-risk hematological and oncological patients on the clinical effectiveness of this approach are sparse. Methods We conducted a before-after single center study accompanying the introduction of such caps at our department. Retrospective data from the year prior to the introduction were compared to 1 year of prospective data. Results The control and antiseptic barrier cap (ABC) groups consisted of 309 and 289 patients present…

RECYCLING SPENT COFFEE WASTE FOR INNOVATIVE THERMO-PLASTERS: DEVELOPMENT OF A PROTOTYPE

2022

This paper presents an experimental study aimed at testing the real energy performance of a thermo-plaster prototype made of an ordinary mortar boosted by various percentages of spent coffee ground. That is one of the wastes of the brewing process that are usually disposed of in landfill with great concerns for the possible environmental footprint due to its organic nature and possible harmful components. In this paper, the mortar was manufactured froman ordinary Portland cement and sand, partially substituted by the waste. Specimens characterization is briefly outlined and a careful examination of the thermal properties is carried out. A plastering prototype was manufactured and placed in …

Bond strength of lithium disilicate after cleaning methods of the remaining hydrofluoric acid

2020

Background Complex implant treatments have steadily increased within implant prosthodontics. Based on the lower implant mobility, implant impressions need high accuracy in the model transfer to receive a high passive fit within the final prosthodontic restoration. To analyze the accurate 3-dimensional (3D) inter-implant-positions, a reference point is indispensable. However, there is no reference in the patients mouth, so the aim of the present study was to develop a new method based on a custom-made-measuring-aid (CMA) to assess the inter implant dimensions (InID) in patients. Material and Methods Initially an implant master model (IMM/patient equivalent) was digitized by computed tomograp…

Why adopt ISO 9001 certification in hospitals? A case study of external triggers and sensemaking in an emergency department in Norway

2017

Abstract Background Certification and accreditation are widely used to achieve quality and safety in health care but are also questioned regarding their assumed effects. This is a challenge for policymakers and managers, since adoption of these regimes can have a circumstantial impact upon organizations. This study’s aim was to explore how external conditions catalyzed and triggered organizational change and internal sensemaking processes as part of an ISO 9001 certification process. Methods The study applied an explanatory single-case design, using a narrative approach, to retrospectively follow a sensemaking process in an emergency department in a Norwegian hospital undergoing ISO 9001 ce…

ChemInform Abstract: Bubble Fractionation of Enantiomers from Solution Using Molecularly Imprinted Polymers as Collectors.

2010

Adsorptive bubble separation methods have been used to enrich components from both heterogeneous and homogeneous solutions. These methods are particularly effective for processing large solution volumes at low cost. Previous work demonstrated that chiral, surface-active collectors could be used to enrich enantiomers from homogeneous solution in a foam fractionation process. In a significant extension of this work, the use of highly selective molecularly imprinted polymers (MIPs) and heterogeneous solutions for the bubble flotation of enantiomers was evaluated. The high selectivity and ease of recycling of the MIP make this a potentially powerful approach for process-scale separations from l…

Systematic review with radiomics quality score of cholangiocarcinoma: an EuSoMII Radiomics Auditing Group Initiative

2023

Abstract Objectives To systematically review current research applications of radiomics in patients with cholangiocarcinoma and to assess the quality of CT and MRI radiomics studies. Methods A systematic search was conducted on PubMed/Medline, Web of Science, and Scopus databases to identify original studies assessing radiomics of cholangiocarcinoma on CT and/or MRI. Three readers with different experience levels independently assessed quality of the studies using the radiomics quality score (RQS). Subgroup analyses were performed according to journal type, year of publication, quartile and impact factor (from the Journal Citation Report database), type of cholangiocarcinoma, imaging modali…
