The dataset provides the age and sex structure of hospitalized COVID-19 deaths, and frequent updates are made publicly available by the Ministry of Health (https://opendatasus.saude.gov.br/nl/dataset). Fundao Oswaldo Cruz. Second, in contrast to DT19 and DT20, the method based on the difference in life expectancy between 2019 and 2020 makes no assumption about independence of causes of death (that is, that the risks of dying from other causes are unaffected by the addition or elimination of COVID-19 mortality), an assumption that was almost certainly violated during the pandemic. First, we obtained mid-year population projections for 20182020 and abridged life tables estimated for 20002020 by state, age and sex from the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatstica, or IBGE, in Portuguese) (https://www.ibge.gov.br/en/statistics/social/population/18176-population-projection.html).

Expected Impact : Applicants are expected to define, calculate, explain and achieve ambitious and credible impacts in terms of conservation benefit, ensuring at the same time long term sustainability and . First, as our main specification, we constructed period life tables that considered deaths by state, sex and age group. Manag. We did not make any corrections for the under-registration of deaths.

Preparation of pressure sensitive adhesives from post-consumer superabsorbent polymers. We found a 15.3% and 15.1% decrease in GWP when replacing the industrial route with either the 1min or 2min sonication scenario, respectively, and an impressive 21.5% decrease when sonication was avoided altogether. Chem. Liang, L. et al. The main results presented in the text are based on differences between the 2019 and 2020 life tables, for two primary reasons. Noymer, A. We estimate a decline in 2020 life expectancy at birth (e0) of 1.3 years, a mortality level not seen since 2014.

Death rates from non-COVID-19 causes in 2020 likely changed between 2019 and 2020, decreasing for some causes (for example, from reduced exposure to other infections) and increasing in others (for example, from delayed or foregone healthcare or overburdening of the healthcare system).

Moreover, the route involving just decrosslinking and esterification (i.e., no sonication) has the potential to be industrially scalable, providing a sustainable solution to a longstanding waste problem. LIFE - Support for applicants (europa.eu) Teikti paraik ia. We showed that a largely unmitigated pandemic, in a context of local inequalities, resulted in a high and unequal mortality burden.

Syntheses of pressure-sensitive adhesives from petroleum feedstocks (industrial approach) compared to waste diaper-based feedstock (open-loop recycling).

More specifically, we compared four different cradle-to-product LCA scenarios: poly(2-ethylhexylacrylate) production in the conventional industrial approach and three variations of the recycling process: (i) sonicating the 2.5% w/v polymer solution for 1min, (ii) sonicating the 5.0% w/v polymer solution for 2min, and (iii) no sonication of the 5% w/v polymer solution. Correspondence to Second, we calculated cause-deleted life tables for 2020 (DT20), which examine the consequences of eliminating COVID-19 mortality from 2020 deaths44. Vaupel, J.

To avoid inconsistencies between life tables estimated for 2019 and 2020, we applied the same methodology to 2019. Brazil has been heavily affected by coronavirus disease 2019 (COVID-19). Here, chemical transformations are used to convert waste polymers into other value-added materials, delaying their entry into the waste stream. Projects focussing exclusively on governance are excluded from this Call topic and covered by the related Call topic LIFE-2021-SAP-NAT-GOV. Sci. Different PSAs were targeted simply by varying the sonication times. Ching, T. W. et al. In both countries, the pandemic response in 2020 was disparate regionally, with lamentable national coordination3,4, resulting in a high and unequal mortality burden5,6. b, Estimated change in e65 in 2020 based on the difference from life tables calculated for 2019 and 2020 by state and sex.

In summary, the death toll of COVID-19 in Brazil has been catastrophic. Public Health 17, 4322 (2020). The South was the last region to be severely hit by COVID-19 in 2020 (ref. For 2019 and 2020, our estimates include deaths from all causes registered in the Mortality Information System. Third, because local health authorities have 60 d to report deaths from any cause, delayed death registration might be an issue in 2021, and, thus, for the first 4 months of 2021, we used confirmed COVID-19 deaths as reported by Brasil.io, which compiles epidemiological bulletins from the 27 state health departments. 8,17). Report 19: the potential impact of the COVID-19 epidemic on HIV, TB and malaria in low- and middle-income countries. Because in-hospital COVID-19 deaths represent 89% of all COVID-19 deaths reported in 2021, we use them to proxy for the agesex distributions of all COVID-19 deaths. Sonication has previously been used to chain-shorten high-molar mass polymers with various backbone architectures31,32, including polyacrylic acid33, and has been used at scale34.

Combined, these data indicate that open-loop recycling of the superabsorbent poly(acrylic acid) to synthesize PSAs is both energetically and environmentally favorable compared to petroleum-derived syntheses in our assessment.

Here we report an open-loop recycling method for these materials that involves (i) decrosslinking via hydrolysis, (ii) an optional chain-shortening via sonication, and (iii) functionalizing via Fischer esterification.

Child immunization was reduced, particularly among impoverished children in the North region29. (In contrast to this assumption, the potential dependence between COVID-19 and other causes might lead to modified probabilities of dying from other causes if COVID-19 were eliminated or added as a cause of death.) CAS FaterSMART. Degrad. DT19 and DT20 assess the effect of including and excluding, respectively, only deaths for which COVID-19 was listed as the underlying cause on the death certificate.

The aim of the project is the conservation of Caretta caretta, in the western Mediterranean basin, from threats related to human disturbance in the nesting sites. Assuming that death rates would have been equal to 2019 all-cause rates in the absence of COVID-19, COVID-19 deaths in 2021 have already reduced e0 in 2021 by 1.8 years, which is slightly larger than the reduction estimated for 2020 under similar assumptions.
