Humanity eradicated smallpox 45 years ago. 
It’s a story worth remembering

The US filmmaker Neil Halloran is known for short documentaries that combine illuminating data visualisation with powerful storytelling. In his latest work, The Plea, Halloran explores how smallpox went from perhaps the deadliest infectious disease in human history to a fading memory. The film provides a brief history of smallpox from ancient Egypt to today – almost five decades since the last known smallpox death – replete with charts and graphics that put the vast devastation of the virus into perspective/.../

TThis is a great data-driven short documentary by Neil Halloran about how smallpox was eradicated from the face of the Earth. And what it took was humanity, through the use of science & humanitarianism, answering its own plea for something to be done about it.

See also How smallpox claimed its final victim (I’d never heard this story before watching Halloran’s video), How Children Took the Smallpox Vaccine Around the World, and No One Knows What’s Inside the Smallpox Vaccine./.../

Um dos primeiros cientistas brasileiros à frente da coordenação dos programas de imunização da Organização Pan-Americana de Saúde (OPAS), o epidemiologista Ciro de Quadros faleceu na tarde da quarta-feira, 29 de maio, em Washington, nos Estados Unidos. Nascido em Rio Pardo (RS) em 30/01/1940, Quadros ingressou no curso de Medicina da antiga Escola Católica de Medicina da Santa Casa da Misericórdia de Porto Alegre, atual Universidade Federal de Ciências da Saúde de Porto Alegre (UFCSPA). Ao se formar, foi contratado pela Fundação SESP para trabalhar em Pernambuco e, posteriormente, no Pará.

Recebeu da Organização Mundial da Saúde (OMS) o título de “Herói das Américas em Saúde Pública”. Fez parte do Grupo de trabalho da SSMA do RS, na época em que apresentei a proposta de trabalhar também no controle de Doenças Crònicas ("Não Transmissíveis")

#AEON - The entangled brain

Luiz Pessoa is director of Maryland Neuroimaging Center, principal investigator at the Laboratory of Cognition and Emotion, and professor of psychology at the University of Maryland. He is the author of The Cognitive-Emotional Brain (2013) and The Entangled Brain (2022).

When thousands of starlings swoop and swirl in the evening sky, creating patterns called murmurations, no single bird is choreographing this aerial ballet. Each bird follows simple rules of interaction with its closest neighbours, yet out of these local interactions emerges a complex, coordinated dance that can respond swiftly to predators and environmental changes. This same principle of emergence – where sophisticated behaviours arise not from central control but from the interactions themselves – appears across nature and human society./.../  

............................   

In the end, we need to stop seeking simple explanations for complex mind-brain processes, whether they are viewed as healthy or unhealthy. That’s perhaps the most general implication of the entangled brain view: that the functions of the brain, like the murmurations of starlings, are more complicated and more mysterious than its component parts.

# Visita do Dr. Luiz Maria Cabrera Yordi

Hoje tivemos a gratíssima visita de nosso velho amigo e colega Radiologista e Hemodinamicista. Além da amizade, deu-nos durante muitos anos apoio na investigação radiológica de nossos pacientes cardiopatas ou com suspeita de problemas cardiovasculares. Deixou a prática médica antes de nos, e se dedica a atividades agro-pastoriz no interior do Estado. Foi tão bom nosso encontro que esqueci de documentá-lo com uma foto que vai ficar para a próxima vez.
