Mortality from COVID-19 in Brazil : analysis of death’s civil registry from 2020 January to 2021 February

Objetivo: analisar a evolução da mortalidade por COVID-19 no período de janeiro de 2020 a fevereiro de 2021 no Brasil. Métodos. Dados sobre todos os óbitos foram obtidos do Portal da Transparência, alimentado continuamente pelos cartórios civis do país. Foi considerado óbito por COVID-19 quando havia citação de COVID-19, coronavírus ou novo coronavírus como causa de óbito. As taxas de mortalidade por COVID-19 foram padronizadas por sexo e faixa etária, conforme estimativa populacional para 2020. Mortalidade por COVID-19 proporcional foi calculada por faixa etária e região, conforme o sexo. Mortalidade geral proporcional foi calculada por local de falecimento e região, conforme causa do óbito. Resultados. Dos 1.596.130 óbitos registrados, 16% tiveram COVID-19 como causa básica, a taxa de mortalidade no Brasil foi de 119,9 por 100 mil habitantes, chegando a 410,5 em Roraima para o sexo masculino. Altas taxas foram encontradas principalmente na região Norte e as menores na região Nordeste. A maior proporção foi entre 70 e 79 anos de idade. A morte por COVID-19 em domicílio atingiu 3,8% dos óbitos na região Norte e 3,4% no Nordeste. Conclusões. O uso de dados do registro civil é de grande importância para o monitoramento atualizado da mortalidade por COVID-19, demonstrando que o país enfrenta, em 2021, aumento de óbitos e agravamento da pandemia.Objective: to analyze the evolution of mortality due to COVID-19 in the period from January 2020 to February 2021 in Brazil. Methods. Data on all deaths were obtained from the transparency portal, continuously fed by the country's civil registry offices. It was considered death by COVID-19 when there were citations of COVID-19, coronavirus or new coronavirus in the cause of death. Mortality rates for COVID-19 were standardized by sex and age group, according to a population estimate for 2020. Proportional COVID-19 mortality was calculated by age group and region, according to sex. General proportional mortality was calculated by place of death and region, according to the cause of death. Results. Of the 1,596,130 deaths recorded, 16% had COVID-19 as a basic cause, the mortality rate in Brazil was 119.9 per 100 thousand inhabitants, reaching 410.5 in Roraima for men. High rates were found mainly in the North and lowest in the Northeast. The highest proportion was between 70 and 79 years of age. Death by COVID-19 at home reached 3.8% of deaths in the North and 3.4% in the Northeast. Conclusions. The use of civil registry data is of great importance for a timely monitoring of COVID-19 mortality, thus showing the country faces, in 2021, an increase in deaths, worsening the pandemic

Trends in COVID-19 case-fatality rates in Brazilian public hospitals : a longitudinal cohort of 398,063 hospital admissions from 1st March to 3rd October 2020

Almost 200,000 deaths from COVID-19 were reported in Brazil in 2020. The case fatality rate of a new infectious disease can vary by different risk factors and over time. We analysed the trends and associated factors of COVID-19 case fatality rates in Brazilian public hospital admissions during the first wave of the pandemic

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic.

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
