Mortalidade na area da Unidade Sanitaria Murialdo, Porto Alegre, RS, 1987

Dada a importância do conhecimento da situação de saúde a nível local, objetivou-se caracterizar a mortalidade na área da Unidade Sanitária Murialdo na zona leste de Porto Alegre, Brasil. Através da revisão dos atestados de óbito, obteve-se um coeficiente de mortalidade geral (4,83/1.000 habitantes) inferior ao da cidade (6,63/1.000) e do estado (6,43/1.000) e um coeficiente de mortalidade infantil (20,99/1.000 menores de um ano) superior ao de Porto Alegre (19,94/1.000) porém inferior ao do Rio Grande do Sul (22,01/1.000). A mortalidade proporcional é maior em estratos mais jovens que a verificada em Porto Alegre e no Rio Grande do Sul, predominando os óbitos por doenças crônico-degenerativas. Há um pequeno excesso de óbitos no inverno. Enfatiza-se a necessidade da unidade sanitária continuar desenvolvendo atividades preventivas.Mortality was investigated in tire area of tire "Murialdo Sanitary Unit" through 1987's death certificates. This is a local health system of Porto Alegre, capital of Rio Grande do Sul, the southeast state of Brazil. The general mortality rate (4,83/1.000 habitants) of this area was lower than that of the city (6,63/1.000) and of the State (6,43/1.000). The infant mortality rate (20,99/1.000 habitants less than 1 year of age) was higher than that of Porto Alegre (19,49/1.000), but lower than that of Rio Grande do Sul State (22,01/1.000). There is proportionally greater mortality among the young of this area in comparison with Porto Alegre and the Rio Grande do Sul. The predominating causes of death are chronic degenerative diseases. There is a small seasonal excess of death in the winter. These facts stress the need for a continued development of the preventive activities of the "Sanitary Unit”

Rapid and Repetitive Inactivation of SARS‐CoV‐2 and Human Coronavirus on Self‐Disinfecting Anionic Polymers

Abstract While the ongoing COVID‐19 pandemic affirms an urgent global need for effective vaccines as second and third infection waves are spreading worldwide and generating new mutant virus strains, it has also revealed the importance of mitigating the transmission of SARS‐CoV‐2 through the introduction of restrictive social practices. Here, it is demonstrated that an architecturally‐ and chemically‐diverse family of nanostructured anionic polymers yield a rapid and continuous disinfecting alternative to inactivate coronaviruses and prevent their transmission from contact with contaminated surfaces. Operating on a dramatic pH‐drop mechanism along the polymer/pathogen interface, polymers of this archetype inactivate the SARS‐CoV‐2 virus, as well as a human coronavirus surrogate (HCoV‐229E), to the minimum detection limit within minutes. Application of these anionic polymers to frequently touched surfaces in medical, educational, and public‐transportation facilities, or personal protection equipment, can provide rapid and repetitive protection without detrimental health or environmental complications
