Screening of Impulse Control Disorders and Addictions

Introduction: The questionnaire for the screening of impulse control disorders and addictions is a screening scale of eight specific behaviors. Its validation and use is due to the need for a brief and reliable instrument for clinical screening in Cuba. Objective: Describe the results of research in which the questionnaire for the screening of impulse control disorders and addictions in Cuba has been used. Methods: A qualitative phenomenological study was carried out based on the documentary review and content analysis of the four research in which the questionnaire for the screening of impulse control disorders and addictions in Cuba was used Results: In the validation process, a Cronbach's alpha of 0.7502 and higher than 0.7 was obtained for all scales. Risk behaviors related to videogames were identified in about 25% of the participants, and the existence of a positive correlation between addictive risk and emotional dysregulation was verified. During the COVID-19 pandemic, men in the highest risk categories predominated in the alcohol abuse/dependence scale (70.8%).Conclusions: Between 2018 and 2022, four research was carried out in Cuba using the questionnaire for the screening of impulse control disorders and addictions. They included validation based on its adaptation to the Cuban sociocultural context, its use as a baseline in preventive interventions, and as an evaluation technique in a secondary level health care consultation © Este material es publicado según los términos de la Licencia Creative Commons Atribución–NoComercial 4.0.

Teaching Microextraction Techniques During COVID-19 Pandemic through Remote Lab Strategy

Since the appearance of the COVID-19 pandemic and its subsequent stage, the changes produced in the chemistry teaching process have allowed educators to use a wide range of strategies, methodologies, and tools to promote student learning. To carry out laboratory practices, some strategies reported include the use of simulators and educational software, as well as the development of remote lab activities. In recent years, the teaching of microextraction techniques and the greening of the sample treatment process represent an important topic in instrumental analytical chemistry courses, incorporating green chemistry topics in the curricula. In this context, a hands-on activity through a kit of materials, equipment, and reagents delivered to students for teaching microextraction techniques during the pandemic's learning conditions is presented. The activity was designed to extract a food coloring dye applying four microextraction techniques, including solid-phase extraction (SPE), solid-phase microextraction (SPME), in-tube solid-phase microextraction (IT-SPME), and micro polymeric magnetized bar adsorptive extraction (μ-PMBAE). Finally, for quantitative analysis, a colorimetry and absorbance-based experiment through image acquisitions and RGB analysis was used. The experiments were applied as extracurricular activities, and students' feedback was fruitful due to the enthusiasm that it produced in them to carry out laboratory tasks after so much time of confinement. Among the successful points of the activity, it is possible to mention the ease of carrying out the experiments from home and the application of green sample treatment techniques that minimize the use of materials and reagents. © 2023 American Chemical Society and Division of Chemical Education, Inc.

Teaching Instrumental Analytical Chemistry in the Framework of COVID-19: Experiences and Outlook

Significant changes in the teaching-learning process have occurred since the appearance of the COVID-19 pandemic caused by the SARS-CoV 2 coronavirus, due to the limited mobility and closure of university education centers. In this context, essential challenges were presented for teachers and to finish the academic courses by addressing the programmatic;contents without undermining the learning quality. Likewise,en the teaching of upper-division undergraduate. subjects with a high academic load in laboratory practices represents a greater difficulty, since these competencies are acquired in the classroom teaching system. In this communication, the authors present the experiences, difficulties, and results obtained in the teaching of instrumental' analytical chemistry and its applications for biological samples analysis, focused on the access to technology, learning of practical;skills, and evaluation of student learning of a public university, in the context of COVID-19 disease.
