Genetic risk ,COPD ,COVID-19 - Abstract
People with chronic obstructive pulmonary disease (COPD) constitute one of COVID-19 risk groups for poor prognosis upon infection. Variability in predisposition and clinical response to COVID-19 exist but our understanding of these factors in the COPD population is limited. This study explored the genetic background as a possible answer to COVID-19 infection response heterogeneity, either for the poor prognosis in people with COPD or across healthy worldwide populations. Significant SNPs (susceptibility: rs286914/rs123297601–3; severity: rs657152/rs113859424) were selected from the literature and their allelic frequencies5,6 used to calculate the probability of having multiple risk alleles in both our COPD cohort and each worldwide population. A polygenic risk analysis was conducted in the COPD cohort for the two mentioned phenotypes, and for hospitalization and survival to COVID-19 infection. No differences in genetic risk for COVID-19 susceptibility, hospitalization, severity or survival were found between people with COPD and the control group (all p-values>0.01), either considering risk alleles individually, allelic combinations or polygenic risk scores. Alternatively, all populations, even those with European ancestry (Portuguese/Spanish/Italian), showed significant differences from the European population in genetic risk for COVID-19 susceptibility and severity (all p-values

People with chronic obstructive pulmonary disease (COPD) constitute one of COVID-19 risk groups. Variability in predisposition and clinical response to COVID-19 exist but our understanding of these factors in the COPD population is limited. This study explored the genetic background as a possible answer to COVID-19 infection response heterogeneity, either for the poor prognosis in people with COPD or across worldwide populations. Our cohort comprises 255 people with COPD (66±9 years; 72% male; FEV1 53.01±20.31% predicted) and 243 controls (67±10 years; 80% male; FEV1 100.46±19.19% predicted) clinically characterized and genotyped using saliva samples. COVID-19 associated SNPs (susceptibility: rs286914 and rs12329760; and severity: rs657152 and rs11385942) were assessed in our cohort and in the major world populations. Allelic frequencies were used to calculate the probability of having multiple risk alleles. Polygenic risk analysis was also conducted, in our cohort, for the two mentioned phenotypes (susceptibility and severity). No differences in genetic risk for COVID-19 susceptibility or severity were found between people with COPD and the control group (all p-values>0.01), either considering risk alleles individually, allelic combinations or polygenic risk scores. All populations, even those sharing European ancestry (Portuguese, Spanish and Italian), showed significant differences from the European (all p-values

Alternatively, all populations, even those with European ancestry (Portuguese, Spanish and Italian), showed significant differences from the European population in genetic risk for COVID-19 susceptibility and severity (all p-values < 0.0001). Our results indicated a low genetic contribution for COVID-19 infection predisposition or worse outcomes in people with COPD. Also, our study unveiled a high genetic heterogeneity across major world populations for the same alleles, even within European subpopulations. published

- Abstract
The waste management and the role of waste pickers as environmental agents have been gaining prominence in recent years due to the sanction of Brazilian National Policy of Solid Waste. The objective of this paper is to verify the economic development promoted by the improvement in the income of the population of the Structural Administrative Region, in Distrito Federal, which provided a decrease in the Gini index. Besides, also this paper has as objective, to analyze the conditions of waste pickers organized in associations and cooperatives in the process of waste management. In order to reach this purpose, we used as a basis the District Search Household Sampling - PDAD held by CODEPLAN in 2004 and 2011. Based on data presented in PDAD 2004 and 2011, it was found an improvement in family income of the population, resident at Structural region. These results were represented by the decrease of the families with income until two minimum wages and the increase of the families with incomes of two to five minimum wages. However, by restricting this research to waste pickers, it was found that they have income near to one minimum wage monthly. [ABSTRACT FROM AUTHOR]

- Abstract
Objectives: Life events have important effects on psychological well-being. Yet, studies have mainly focused on exploring the impact of traumatic and negative experiences on health and well-being, with positive events receiving marginal attention. In this study, we investigated the association between negative and positive life events, cognitive performance and psychological status in older individuals., Method: A cross-sectional approach with a sample of 97 community-dwelling adults, recruited from a network of 23 centres/institutions in Northern Portugal, and aged between 56 and 85 years, was conducted. All participants were evaluated through a battery of tests assessing for depressive mood, perceived stress, and cognitive functioning. Life events were measured using the Lifetime Experiences Scale (LIFES) which covers 75 life experiences organized in eight domains., Results: A total of 95.9% of the participants reported more positive life events than negative throughout life. Participants reporting more positive experiences had lower scores in the depressive mood and perceived stress measures. At the domain-level of LIFES scale, more negative experiences in the Work and Health domains were associated with a depressed mood and more perceived stress. Significant positive associations were found between positive life experiences and most cognitive measures, after controlling for sex, education, age and depressive symptoms. Namely, more positive experiences at School, Leisure, and Living conditions were positively associated with better performance across cognitive tests., Discussion: This study adds important evidence on the association between of life events, both negative and positive experiences, on cognition and psychological well-being, providing a more balanced view of the field., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2021 Published by Elsevier Inc.)
