Specialized nursing terminology for the care of people with COVID-19.

Objective: To create specialized nursing terminology for the care of people with COVID-19.

Methods: Methodological study, carried out based on the identification of concepts related to the care of the person with the infection, present in the official guidelines of the Brazilian Ministry of Health; the concepts were validated by three specialist nurses; and a cross-mapping of the extracted concepts was done with CIPE® 2019 primitive concepts.

Results: Out of 436 unique concepts, being 399 of these validated; of these, 70.

The polytetrafluoroethylene (PTFE) channel model of cyclic-buildup biofilm and traditional biofilm: The impact of friction, and detergent on cleaning and subsequent high-level disinfection.

Objective: To evaluate the efficacy of detergent and friction on removal of traditional biofilm and cyclic-buildup biofilm (CBB) from polytetrafluoroethylene (PTFE) channels and to evaluate the efficacy of glutaraldehyde to kill residual bacteria after cleaning.

Methods: PTFE channels were exposed to artificial test soil containing 108 CFU/mL of Pseudomonas aeruginosa and Enterococcus faecalis, followed by full cleaning and high-level disinfection (HLD) for five repeated rounds to establish CBB. For traditional biofilm, the HLD step was omitted.

A novel polytetrafluoroethylene-channel model, which simulates low levels of culturable bacteria in buildup biofilm after repeated endoscope reprocessing.

Background And Aims: Clinical studies have shown variable culture results from flexible endoscope channels possibly because of low levels of bacteria that are difficult to extract. The aim of this study was to develop a simulated-use buildup biofilm (BBF) model that mimics low levels of viable bacteria after repeated rounds of aldehyde fixation and accumulation.

Methods: New endoscope channels were exposed to 8 days of repeated rounds of biofilm formation using ATS2015 containing Enterococcus faecalis and Pseudomonas aeruginosa, rinsing, fixation with glutaraldehyde, and rinsing.

Evaluation of the effectiveness of manual and automated dialyzers reprocessing after multiple reuses.

A cross-sectional study was conducted to evaluate the effectiveness of manual and automated dialyzer reprocessing. Dialyzers were filled with fluid thioglycollate medium from blood and dialysate chambers after being reprocessed and chemically sterilized with 0.2% peracetic acid.

Efficacy and effectiveness of alcohol in the disinfection of semi-critical materials: a systematic review.

Objective: to assess the efficacy and the effectiveness of 60-80% alcohol (v/v) in the disinfection of semi-critical materials which were either previously cleaned or not.

Method: studies obtained from BIREME, IBECS, MEDLINE, ScIELO, PubMed, Ask Medline web portals, and references from other studies. Criteria were created to assess the methodological quality of articles.

Effectiveness of flexible gastrointestinal endoscope reprocessing.

The practice of reprocessing endoscopes and its effectiveness was evaluated in 37 services. Contamination of at least 1 endoscope could be identified in 34 (91.6%) of 37 services.

Analysis of the air/water channels of gastrointestinal endoscopies as a risk factor for the transmission of microorganisms among patients.

Background: For the effective reprocessing of gastrointestinal endoscopes, contaminants must be removed from the entire surface. However, these devices have long and narrow channels that can make this process difficult.

Methods: In this cross-sectional study, the staff assigned to reprocess gastroscopes and colonoscopes in 37 services located throughout Brazil completed a questionnaire regarding reprocessing practices geared toward the channels in these devices.
