Terminology behaviour in the context of coronavirus disease

The main objective of this mixed research, qualitative and quantitative, was to analyze the characteristics of the neologisms coined in the context of the coronavirus disease. For this purpose, the researcher worked with a corpus made up of 831 coronavirus neologisms extracted from Hispanic journalistic sources, dictionaries on COVID-19 and neology observatories. The results obtained allowed the following conclusions to be drawn: The coronavirus neology has a high percentage of expressive neologisms with great thematic dispersion. Neologisms based on total or partial blending were the privileged resource in the coining of expressive coronavirus neologisms. The systematic instability of the coronavirus neology was reflected in the considerable denominative variation existing in the two types of neology, in the variety of methods for coining neologisms used for the same referent and in the different thematic nodes in which these variants appear. © Copyright 2022 by the Infectious Diseases and Clinical Microbiology Specialty Society of Turkey.

THE LEARNING OF CHEMISTRY WITH THE SUPPORT OF ICT: NEED OR OPPORTUNITY

Due to the duration of the COVID-19 pandemic, Cuban Higher Education has had to accelerate the development of remote teaching through the EVEA platform. In the case of the Chemistry Degree at the University of Havana, a specialty with a highly experimental component, this has been a great challenge. The transformations carried out for the learning of Organic Chemistry in a remote way are studied. A mixed research strategy was used, integrating theoretical and empirical methods with the aim of evaluating what was done as a pedagogical innovation and to propose actions for its improvement. The actions taken and the behavior of the students regarding the new learning strategy are discussed. Through a survey, the students' criteria are evaluated in relation to technological and connectivity aspects, training aspects, didactic aspects and communication aspects. In general, satisfactory results were obtained and the students valued the experience positively. It reflects on the actions carried out that as good practices can be generalized and the necessary improvements to be made in the use of ICT for learning the Organic Chemistry.

MEDIIK: Design and Manufacturing of an Emergency Ventilator against COVID-19 Pandemic

Herein we describe the modular design and manufacturing of an emergency ventilator based on cyclical compression of a resuscitation bag to face the COVID-19 pandemic. This was done to mitigate the staggering conditions to supply these medical devices under challenging scenarios of need and logistics. The design is based on international standards and commissions for medical electrical equipment, particular requirements for basic safety, electromagnetic compatibility, and essential performance of critical care and emergency ventilators. The modular design is capable of providing four ventilation modes: volume/pressure mandatory ventilation and volume/pressure assisted ventilation. After testing with artificial lungs, calibration, and validation instruments it was found that the main ventilation parameters achieved are: maximum tidal volume of 700 mL, maximum pressure of 50 cmH2O, inspiration/expiration ratio up to 1:4 at 30 breaths per minute. The MEDIIK designation is derived from the mayan word ik' which means wind. © 2021 ACM.

Pharmacokinetic interactions of azithromycin and clinical implication

Introduction: The severe acute respiratory syndrome (due to COVID-19) is currently the leading cause of death in Peru, so effective and safe drugs are required to mitigate the disease. A bibliographic search was carried out in SciELO and PubMed/Medline, 37 of 58 articles on the topic were selected. Objectives: Review and integrate the information on the pharmacokinetic interactions of azithromycin that are prescribed in the outpatient treatment of COVID-19 in Peru, and evaluate their clinical implication. Development: Azithromycin is used in COVID-19, due to its anti-inflammatory activity, by inhibiting interleukins (IL1, 6, 8 and TNF-α), and intracellular adhesion molecules 1 (ICAM1), and by inducing the production of type I interferon (IFN-α, IFN-β) and III (IFN-λ) in cells of patients with chronic obstructive pulmonary disease. The three-arm, randomized and open-label studies indicate that azithromycin does not cause changes in the pharmacokinetic parameters of ivermectin, sildenafil, rupatadine, and desloratadine, single-center, open-label, non-fasting, and two-period studies show that azithromycin influences the pharmacokinetic parameters of venetoclax and psychotropics. Conclusions: Based on the evidence from the reviewed and integrated clinical studies, it is concluded that these are limited and of little clinical relevance, however, it is proposed to use the antibiotic under the scientific criteria of the doctor, to avoid pharmacokinetic interactions and adverse reactions of drugs. © 2021, Editorial Ciencias Medicas.
