Prospective cohort study to evaluate premedication with simethicone and n-acetilcysteine for upper diagnostic gastrointestinal endoscopy.

Introduction: The use of premedication for upper gastrointestinal endoscopy (UGE) is not widely established in western countries. The primary aim of the study was to compare gastric visibility according to the total visibility score (TVS). The secondary aim was to assess complications, diagnostic yield, endoscopic procedure time, sedation dose and patient satisfaction.

A First Assessment of an Aerodynamic Barrier Layer for Filtering Airborne Hygroscopic Particles.

In this work, consideration is given to an aerodynamic concept to boost the filtration in face masks of airborne hygroscopic particles such as those caused by an infected person when coughs or sneezes. Nowadays, increasing the filtration efficiency of face masks implies either increasing the number of crisscrossing fiber layers or decreasing the equivalent hydraulic diameter of the pore, however, both measures are in clear detriment of its breathability. Here, a novel strategy is proposed in which the filtration of an airborne particle is boosted by increasing its diameter.

The mechanical effect of moisturization on airborne COVID-19 transmission and its potential use as control technique.

Mounting evidence from scientific community seems to suggest that COVID-19 virus can potentially spread by airborne transmission. As a result, methods and techniques for preventing environmental contagious, such as ventilation or air filtration have been proposed. Here, it is investigated the effect of moisturization on airborne COVID-19 transmission from a mechanical point of view in which comparatively large water droplets promote the growth -by collision and coalescence, of suspended airborne COVID-19 and then accelerating its gravitational settling.

Randomized clinical trial to assess the mPADSS scale in recovery and home discharge after endoscopy.

Background: current clinical practice guidelines recommend the use of objective scales as a criterion for post-endoscopy sedation discharge.

Objective: to assess the recovery time, complications and patient satisfaction level using the mPADSS scale.

Material And Methods: demographic data and medical history were collected.
