Effects of Pancreatic Fistula After Minimally Invasive and Open Pancreatoduodenectomy.

Importance: Postoperative pancreatic fistulas (POPF) are the biggest contributor to surgical morbidity and mortality after pancreatoduodenectomy. The impact of POPF could be influenced by the surgical approach.

Objective: To assess the clinical impact of POPF in patients undergoing minimally invasive pancreatoduodenectomy (MIPD) and open pancreatoduodenectomy (OPD).

The Evolution of Active Learning in Response to the Pandemic: The Role of Technology.

Active learning has consistently played a significant role in education. Through interactive tasks, group projects, and a variety of engaging activities, students are encouraged to forge connections with the subject matter. However, the pandemic has necessitated that educators adapt and refine their active learning techniques to accommodate the online environment.

COI Barcodes combined with multilocus data for representative Aporia taxa shed light on speciation in the high altitude Irano-Turanian mountain plateaus (Lepidoptera: Pieridae).

Even though the high plateaus of Qinghai-Tibet and Iran share many faunal elements, the historical biogeography of the species present in this area are not very well understood. We present a complete COI barcode library for Aporia Hübner and a first comprehensive phylogeny for the genus including all known species and majority of subspecies using ten available genes (COI-COII, ND1, ND5, Cytb, EF-1a, Wg, 16S, 28S-D2/D3 and 28S-D8). We then focus on A.

Protein detection by fluorescence of manually cleaned high-speed dental handpieces.

We analyzed the effectiveness of manual cleaning protocols performed on high-speed dental handpieces, using protein identification by fluorescence. Although one protocol was able to able to lower the amount of protein, >40% of the handpieces showed amounts of residual protein at unacceptable levels.

Impact of negative pressure system on microbiological air quality in a Central Sterile Supply Department.

Objective: Guidelines recommend that the cleaning area in a Central Sterile Supply Department (CSSD) maintain a negative pressure of the environmental air, but how much this system can impact the contamination of the air by bioaerosols in the area is not known. The objective of this study was to assess the impact of negative pressure on CSSD by evaluating the microbiological air quality of this sector.

Methods: Microbiological air samples were collected in two CSSD in the same hospital: one with and one without a negative air pressure system.

Review: Trends in Processing Prion-Contaminated Surgical Instruments.

This review sought to provide an overview of proposed methods and protocols for processing surgical instruments contaminated with prions. A search of PubMed was conducted to identify studies published between January 1, 2012, and January 2, 2019, with no language restrictions and using varying combinations of the following terms: prions (Medical Subject Heading [MeSH]) OR decontamination (MeSH) OR cleaning OR disinfection OR sterilization. Articles were excluded if they did not involve medical device surfaces or describe the processing protocol.

The Effect of Brush Motion and Rinsing When Manually Cleaning Cannulated Medical Devices.

Cleaning cannulated medical devices can be challenging for perioperative and sterile processing department personnel. We performed a laboratory experimental study to evaluate differences in cleaning effectiveness using either a back-and-forth or helical spinning brushing motion and the effect of rinsing the bristles at each reintroduction of the brush in the lumen. We also tested the lumen cleanliness after high-pressure water cleansing without brushing.

False positive results of Bowie and Dick type test used for hospital steam sterilizer with slower come-up ramps: A case study.

Objective: To determine if the standardized B&D type test for hospital steam sterilizer is correctly indicating cycle failures in slower come-up ramps cycles.

Methods: Two commercially available B&D type test were challenged in a quality control sterilizer. A common failure was simulated in triplicate cycles, using a standardized cycle configuration, and then compared to triplicate cycles of a common cycle configuration.

: Recovery of Microorganisms in Nonsterile, Reusable, Loaned Orthopedic Implants.

Currently, there are two orthopedic implant types: (1) Sterile implants (e.g., joint prostheses) are distributed in a ready-for-use sterile fashion, and (2) nonsterile implants (e.

Norovirus recovery from floors and air after various decontamination protocols.

Background: The dispersal of airborne norovirus (NoV) particles from the floor after contamination with faeces or vomit is a challenge for infection control, as this pathogen is infectious at low doses. Therefore, it is imperative to establish a safe protocol for floor decontamination.

Aim: To assess the presence of residual NoV-GII particles on floors and airborne particles following various floor decontamination procedures.

[Written tests analysis under the principles of authentic assessment. A comparative study of written tests of medical and other undergraduate programs].

Background: Learning assessment has great impact in students' achievement. However, it is one of the least intervened and researched areas in higher education institutions, all over the world.

Aim: To compare the written tests applied to students of three health science undergraduate programs (Speech Therapy, Medical Technology and Nursing), with the written tests of three programs of other areas (Business and Administration, Psychology and Bioengineering).

Manual and Automated Cleaning Are Equally Effective for the Removal of Organic Contaminants From Laparoscopic Instruments.

OBJECTIVE To compare the effectiveness of manual and automated methods for cleaning laparoscopic instruments. DESIGN Experimental laboratory study. METHODS We evaluated 4 methods of cleaning laparoscopic instruments: (1) manual-only cleaning and rinsing with potable tap water; (2) manual cleaning and rinsing with potable tap water, followed by ultrasonic cleaning without rinsing; (3) manual cleaning and rinsing with potable tap water followed by ultrasonic cleaning and rinsing with potable tap water; and (4) manual cleaning and rinsing with potable tap water, followed by ultrasonic cleaning and rinsing: first with potable tap water and then with sterile distilled water.

The practice of disinfection of high-speed handpieces with 70% w/v alcohol: An evaluation.

A high-speed handpiece is used in several dental procedures and the official recommendation for safe decontamination consists of rinsing with water, washing with detergent, mechanical friction, and sterilization; however, many professionals only apply 70% w/v alcohol without also cleaning the tool between patients. We performed an analysis of high-speed handpieces reprocessed only with 70% w/v alcohol and found that the methods used in clinical practice are not safe.

The samples were enamelled surfaces, intentionally contaminated with Serratia marcescens microorganisms ATCC 14756 106 CFU/mL with 10% of human saliva added, and were submitted to the procedure of disinfection WITHOUT previous cleaning.

[Temperature and humidity in the storage area of sterile materials: a literature review].

The recommendations for temperature (T°) and relative humidity (RU) for the storage of sterilized materials in Sterilization Central Supply (SCS) vary according to different sources, and are not based on theoretical frameworks or experiments. The practice shows difficulties in controlling these parameters, leading to doubts regarding the maintenance of the sterility of these materials. This article proposed, through a literature review, to identify and analyze the recommendations for T° and RU for the sterile storage area.
