RESUMO

Introduction: The COVID-19 pandemic has accelerated universities' adaptation process toward online education, and it is necessary to know the students' attitudes toward this online education. Objective: To describe the evolution of the attitude toward online education among social science students at a public university in Peru in the academic year 2020, in the context of the COVID-19 pandemic. Methods: The study uses a quantitative approach, a descriptive level, a non-experimental design, and a longitudinal trend. The sample consisted of 1063 students at the beginning of the class period, 908 during the classes, and 1026 at the end of the class period. The questionnaire for data collection was the Attitude scale toward online education for university students during the COVID-19 pandemic. The data was collected using Google Forms. Results: As a result, the attitude towards online education was predominantly weak negative at the beginning (51.1 %) and during the classes (49.1 %), and weak positive (48.1 %) at the end of the class period. The changes were not significant when comparing the three moments, the levels of attitude toward, intention to adopt, ease of use, technical and pedagogical support, stressors, and need for online education (p-value <0.05). Conclusion: The evolution of the attitude towards online education in the sample had a non-significant positive trend. In the initial and process stages, a weak negative attitude prevailed due to the institution's inexperience and poor digital infrastructure; in the end, the attitude became weak and positive due to the adaptation and need for online education.

RESUMO

Background: climate change is a reality, and more and more people are becoming aware of this global problem, which has generated anxiety in some populations. To validate a short survey to assess eco-anxiety in adults in South America. Methods: It is an instrumental study, and the validation was based on a previous survey, which had six questions and was generated by 217 respondents in the USA in 2021. These questions were subjected to a validation process with expert judgment, pilot and application, and then statistics were obtained. It was validated with 1907 people in six countries in South America, where the mean, standard deviation, skewness and kurtosis were adequate. Results: The initial confirmatory factorial model obtained unsatisfactory goodness-of-fit indices, so the indices were modified through a re-specification, where two items were eliminated, after which adequate values were obtained (χ2 = 22.34, df = 2, p = 0.00; RMR = 0.020; GFI = 0.990; CFI = 0.990; TLI = 0.990; and RMSEA = 0.070). Finally, the overall Cronbach's α was calculated to be 0.88 (95% CI = 0.86-0.89). Conclusions: The test was validated in a large South American population and found that only four questions can efficiently measure anxiety about the effects of climate change. The instrument can be used with other tests to screen different age groups, ethnicities and realities.

RESUMO

Objective: The current study's objective is to characterize a new throm-bin-like enzyme called TLBro that was obtained from Bothrops roedingeris snake from a biochemical and hemostatic perspective. Methodology: One chromatographic step was used to purify it, producing the serine protease TLBro. Molecular mass was estimated by SDS-PAGE to be between reduced and unreduced by 35 kDa. Tryptic peptide sequencing using Swiss Prot provided the complete amino acid sequence. Expasy.org by conducting a search that is limited to Crotalinae snake serine proteases and displaying a high degree of amino acid sequence. Results: Ser (182) is inhibited by phenylmethylsulfonyl fluoride (PMSF), and TLBro demonstrated the presence of Asp (88) residues. It also deduced the positions of His (43) and Ser (182) in the set of three coordinated amino acids in serine proteases. It was discovered that this substrate had high specificity for BANA, Michaelis-Menten behavior with KM 0 point85 mM and Vmax 1 point89 nmoles -NA/L/min, and high stability between temperatures (15 to 70°C) and pHs (2 point0 to 10 point0). According to doses and incubation times, TLBro degraded fibrin preferentially on the B-chain; additionally, its activities were significantly diminished after preincubation with divalent ions (Zn2 and Cd2). When incubated with PMSF, a particular serine protease inhibitor, enzymatic activities and platelet aggregation were inhibited. Conclusion: The findings revealed distinct structural and functional differences between the serine proteases, adding to the information and assisting in the improvement of the structure-function relationship.

RESUMO

Introduction: The publication of articles on the circular economy has different associated factors to explain the citations registered in the Web of Science. Method: Articles from the publishers Elsevier, MDPI, Taylor & Francis, Wiley, and Springer Nature were evaluated. Results: It was expected that the older the article was, the more citations it had received, but this was not always the case. It was also recognized that there was a lower number of citations if the articles were too large or if they had too many references. Discussion: This analysis helps to establish the factors that must be addressed in order to publish in journals that have a high citation rate. Conclusion: Based on speci?c articles and with speci?c references, it will be possible to increase the probability of citations.

RESUMO

Sustainability may be at risk in a population that has altered health, according to Sustainable Development Goal 3 (SDG 3): Health and well-being. The ongoing conflict between Russia and Ukraine could jeopardize SDG 3, specifically the mental health of the population. The present study sought to determine the association between severe anxiety, depression and stress in population of 13 Latin American countries according to fear about the war conflict. It was a cross-sectional, analytical and multicenter study. Anxiety, depression and stress were measured with the DASS-21 test (Cronbach's Alpha: 0.97) and fear due to an armed crisis with a questionnaire already validated in Latin America (Cronbach's Alpha: 0.92), which was also adjusted for sex, age, education level and country of residence. Descriptive and analytical statistics were obtained. Of the 2,626 respondents, the main fear was that weapons of mass destruction would be used. In the multivariate models, strong associations were found between fear of a possible world-scale armed conflict and having severe or very severe levels of anxiety (aPR: 1.97; 95% CI: 1.64-2.36; value of p <0.001), depression (aPR: 1.91; 95% CI: 1.54-2.36; value of p <0.001) or stress (aPR: 2.05; 95% CI: 1.63-2.57; value of p <0.001). Sustainability linked to SDG 3, specifically mental health, is affected by this type of significant events, given the possible global war crisis that could trigger major events, even more so if added to the deterioration already experienced by COVID-19 in the Latin American region, insecurity and constant political uncertainty.

RESUMO

Introduction: Latin America was the region most affected by COVID-19 in the second quarter of 2020, and consequently, the impact on mental health requires evaluation. The aim of this study was to assess the risk of post-traumatic stress disorder (PTSD) caused by bereavement due to COVID-19 in 12 countries in Latin America. Methods: The current study was an analytical cross-sectional study. Validated tests were applied for PTSD, depression, anxiety, and stress (DASS-21), questions about the respondent's condition or their environment, and demographic questions, as well as the length of the mourning period of suffering. Results: The outcomes demonstrated that the PTSD risk increased for women (p < 0.001), when a friend or acquaintance had COVID-19 (p = 0.002), when a close relative died from COVID-19 (p = 0.010), having severe depression (p <0.001), severe anxiety (p <0.001), severe stress (p <0.001), residing in Chile (p <0.001), Paraguay (p <0.001), Bolivia (p <0.001), Costa Rica (p <0.001) or El Salvador (p = 0.005). On the other hand, there was less risk of PTSD at an older age (p <0.001) or if respondents had a sentimental partner (p = 0.025). In the case of severe PTSD, there was a greater gender risk for women (p <0.001), a close relative dying from COVID-19 (p = 0.017), having severe depression (p <0.001), severe anxiety (p <0.001), severe stress (p <0.001), residing in Chile (p <0.001), Paraguay (p <0.001), Bolivia (p <0.001) and Costa Rica (p = 0.002). It was also observed that there was less risk of severe PTSD at an older age demographic (p <0.001). Discussion: It can be concluded that the percentages of PTSD are high in its clinical presentation as severe, especially among Latin American women.

RESUMO

The COVID-19 pandemic has affected and afflicted human lives and been a transformative catalyst leading to closure of many companies, disrupting mental health, and reducing access to food and exacerbating food insecurity. This presents an opportunity to reflect on and examine genetically modified (GM) foods and their effective legislative regulation for the benefit of consumers. This review presents a detailed analysis of GM foods' regulation in Peru and the analysis of certain specific cases that show the need for greater regulation of the industry.

RESUMO

The hospitality industry worldwide is suffering under the COVID-19 pandemic. Drawing on the transactional theory of stress and coping, this study aims to investigate when hospitality workers' COVID-19 risk perception affects their likelihood of having depressive symptoms. Using data from 211 hospitality workers in 76 hotels in Peru, we examined the effects of perceived COVID-19 risk on the likelihood of experiencing depressive symptoms. We posited that this relationship is moderated by the workers' environment at work (job satisfaction) and at home (the number of children). The results indicate that job satisfaction weakens the link between hospitality workers' COVID-19 risk perception and their likelihood of depressive symptoms while the number of children exacerbates this link. We discuss the implications of our findings for research on COVID-19 risk perception and offer practical implications for hospitality workers under COVID-19 crisis.

RESUMO

The COVID-19 epidemic has spawned an "infodemic," with excessive and unfounded information that hinders an appropriate public health response. This perspective describes a selection of COVID-19 fake news that originated in Peru and the government's response to this information. Unlike other countries, Peru was relatively successful in controlling the infodemic possibly because of the implementation of prison sentences for persons who created and shared fake news. We believe that similar actions by other countries in collaboration with social media companies may offer a solution to the infodemic problem.

RESUMO

Aim: This paper examines the barriers in Peruvian community pharmacies for cosmetovigilance practice. Methods: It was obtained information from the pharmacists of 81 community pharmacies in 2 districts in Lima, Peru. For reliability's evaluation, it was used SPSS software V.24. The validity of construct, discriminant validity and, internal consistency by the composite reliability was analyzed with structural equation modelling using partial least square using SmartPLS 3 software. Results: 81 questionnaires self-administered anonymous were completed (response rate = 51.9%). Average of years of working in community pharmacies was more than 6.36 years (SD: 4.63). More than 70% of the participating pharmacists chose the "strongly agree" and "agree" alternative for items about barriers that included: Lack of time, National health system structure in general and My interest to report adverse reaction by cosmetics. About daily activities, more than 70% of the participants chose the "strongly agree" and "agree" alternative for items that included "Rarely I explain to users about adverse reaction with cosmetics use" and "Rarely I have material to inform to users about adverse reaction with cosmetics use". The composite reliability for each latent variable was Resources: 0,766; Interest: 0862; Regulation: 0.815 and Cosmetovigilance Practice: 0.909. Conclusion: The need of the implementation of cosme to vigilance practice is an issue of public health to take responsibility for care customers against cosmetic damage


Objetivo: Este artículo examina las barreras en las farmacias comunitarias en Perú para la práctica de la cosmetovigilancia. Métodos: Se obtuvo información de los farmacéuticos de 81 farmacias comunitarias de 2 distritos de Lima, Perú. Para la evaluación de la fiabilidad, se utilizó el software SPSS V.24. La validez de la variable, la validez discriminante y la consistencia interna de la fiabilidad compuesta se analizaron con el modelado de ecuaciones estructurales usando mínimos cuadrados parciales utilizando el software SmartPLS 3. Resultados: 81 cuestionarios auto-administrados anónimos se completaron (tasa de respuesta = 51,9%). El promedio de años de trabajo en farmacias comunitarias fue más de 6,36 años (DE: 4,63). Más del 70% de los farmacéuticos participantes optó por la alternativa "totalmente de acuerdo" y "de acuerdo" para temas relacionados con las barreras que incluían: Falta de tiempo, estructura del sistema nacional de salud en general e interés en el reporte de reacciones adversas por cosméticos. Acerca de las actividades cotidianas, más del 70% de los participantes eligieron la alternativa "totalmente de acuerdo" y "de acuerdo" para artículos que incluyeron "Rara vez explico a los usuarios sobre la reacción adversa con el uso de cosméticos" y "Raramente tengo material para informar a los usuarios sobre la reacción adversa con el uso de cosméticos". La fiabilidad compuesta para cada variable latente fue Recursos: 0,766; Interés: 0862; Reglamento: 0.815 y Práctica de cosmetovigilancia: 0.909. Conclusión: La necesidad de la implementación de la práctica de cosmetovigilancia es una cuestión de salud pública para asumir la responsabilidad de los clientes de cuidado contra los daños cosméticos
