In this study, we aimed at analyzing the associations between transmission of and deaths caused by SARS-CoV-2 and meteorological variables, such as average temperature, minimum temperature, maximum temperature, and precipitation. Two outcome measures were considered, with the first aiming to study SARS-CoV-2 infections and the second aiming to study COVID-19 mortality. Daily data as well as data on SARS-CoV-2 infections and COVID-19 mortality obtained between December 1, 2019 and March 28, 2020 were collected from weather stations around the world. The country's population density and time of exposure to the disease were used as control variables. Finally, a month dummy variable was added. Daily data by country were analyzed using the panel data model. An increase in the average daily temperature by one degree Fahrenheit reduced the number of cases by approximately 6.4 cases/day. There was a negative correlation between the average temperature per country and the number of cases of SARS-CoV-2 infections. This association remained strong even with the incorporation of additional variables and controls (maximum temperature, average temperature, minimum temperature, and precipitation) and fixed country effects. There was a positive correlation between precipitation and SARS-CoV-2 transmission. Countries with higher rainfall measurements showed an increase in disease transmission. For each

Background: The aggravation of environmental problems has led companies to seek the development and commercialization of green products. Some companies mislead their stakeholders through a phenomenon called greenwashing.Results: This paper aims to explore the phenomenon of greenwashing through a systematic literature review in search of its main concepts and typologies in the past 10 years. This research has followed the proceedings of a systematic review of the literature, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We identified a major classification of greenwashing: firm-level executional, firm-level claim, product-level executional, and product-level claim. Conclusion:It was possible to highlight and catalog the types of the phenomenon. A structure based on such type has been observed in the literature.

Resumo O objetivo desse estudo foi identificar quais categorias de lixo urbano apresentam associação com casos de dengue e, em seguida, avaliar o impacto da coleta de lixo sobre os casos da doença na cidade do Recife. Foram utilizados dados da pesagem categorizada de lixo, juntamente com os casos confirmados de dengue no município. Os dados foram analisados através do coeficiente de correlação de Pearson para as treze categorias de lixo, seguido pela Regressão Linear Multivariada, selecionando as variáveis pelo método de “stepwise”. Identificou-se a existência de correlação negativa entre o total de casos de dengue em sete categorias: lixo domiciliar (r = -0,835), resíduos diferenciados (r = -0,835), resíduos de operações especiais (r = -0,711), entulhos (r = -0,687), coleta seletiva (r = -0,425) e pneus (r = -0,423). O modelo de regressão foi capaz de explicar 75% da variação, apontando que um incremento de 1.000 toneladas na coleta de lixo doméstico proporciona uma redução de 0,032 casos de dengue enquanto que o mesmo incremento na coleta de pneus é capaz de reduzir 0,465 casos da doença. Os resultados demonstram que a coleta de lixo possui um forte impacto negativo nos casos de dengue e podem ser adotados como estratégia de prevenção pelos governos municipais.

Background The determinants of access to immunizers are still poorly understood, leading to questions about which criteria were considered in this distribution. Given the above, the present study aimed to analyze the determinants of access to the SARS-CoV-2 vaccine by different countries. Methods The study covered 189 countries using data from different public databases, and collected until February 19, 2021. We used eight explanatory variables: gross domestic product (GDP), extreme poverty, human development index (HDI), life expectancy, median age, coronavirus disease 2019 (COVID-19) cases, COVID-19 tests, and COVID-19 deaths. The endogenous variables were total vaccine doses, vaccine doses per thousand, and days of vaccination. The structural equation modeling (SEM) technique was applied to establish the causal relationship between the country's COVID-19 impact, socioeconomic variables, and vaccine access. To support SEM, we used confirmatory factor analysis, t-test, and Pearson's correlation. Results We collected the sample on February 19, and to date, 80 countries (42.1%) had already received a batch of immunizers against COVID-19. The countries with first access to the vaccine (e.g., number of days elapsed since they took the first dose) were the United Kingdom (68), China (68), Russia (66), and Israel (62). The countries receiving the highest doses were the United States, China, India, and Israel. The countries with extreme poverty had lower access to vaccines and the richer countries gained priority access. Countries most affected by COVID (deaths and cases) also received immunizers earlier and in greater volumes. Unfortunately, similar to other vaccines, indicators, such as income, poverty, and human development, influence vaccines' access. Thus affecting the population of vulnerable and less protected countries. Therefore, global initiatives for the equitable distribution of COVID need to be discussed and encouraged. Conclusions Determinants of vaccine distribution consider the impact of the disease in the country and are also affected by favorable socioeconomic indicators. The COVID-19 vaccines need to be accessible to all affected countries, regardless of their social hands.

Mild Cognitive Impairment is characterized as an intermediate form between age-related change and dementia. For the elderly, autonomy and independence are related to the ability to remain active in conducting their social activities and, for this to occur, communication is fundamental in this process.Objective:To assess the association between communication and the abilities of elderly people with mild cognitive impairment to perform instrumental activities of daily living.Methods:A cross-sectional, quantitative, analytical, correlational study was conducted at the Open University of the Third Age (UnATI), a program of the Federal University of Pernambuco. This study included 92 people, comprising 46 elderly with mild cognitive impairment and a caregiver or family member who met the inclusion criteria. The elderly were asked to complete a sociodemographic questionnaire and Lawton-Brody’s Instrumental Activities of Daily Living Scale. The caregivers were asked to complete the Functional Assessment of Communication Skills. The following variables were studied: social communication skills and instrumental activities of daily living. Data were stored in an Excel® 2007 spreadsheet, and the Pearson correlation test was used for the statistical analysis.Results:There were statistically significant correlations in four domains of social communication: referring to family members by name (p=0.0033); requesting information about people or events (p=0.0355); understanding conversations in a noisy environment (p=0.0448); and understanding what they watch on television or listen to on the radio (p=0.0127).Conclusion:Changes in the communication of elderly people with mild cognitive impairment interfere with their ability to perform instrumental activities autonomously and independently.
