 3.097 - AMICOR (25)

Reencontrei (07/08/2022) o buquê que em 1987 ela tinha na mão. Imagem já publicada no AMICOR 3.074 do meio do mês de março do corrente ano.

King's Williams Island Finland 1987 - colhendo flores silvestres...

O jardim, era de fato uma reserva ecológica, agreste numa ilha fronteiriça a Helsinki. As flores silvestre que colhemos eu guardei , e até algum tempo se conservavam (secas) protegidas por um plástico. Espero pode reencontrá-las, mesmo que não consiga mais encontrar quem as colheu.

#Fibrose Endomiocárdica
Ao encontrar artigo recente sobre esta doeneça, lembrei de um caso semelhante que esteve sob meus cuidados, em abril de 1960, enquanto Residente chefe no Serviço do Professor Eduardo Záccaro Faraco, da Cátedra de Terapêutica Clínica da Faculdade de Medicina da UFRGS.
Como a Enfermaria 38o da Santa Casa de Misericórdia (Pavilhão Cristo Redentor, 6o. andar) cuidava somente de homens, para que tivéssemos também experiência com pacientes femininas, cuidávamos também das pacientes da Enfermaria 02 (4o. andar) do Professor Thomaz Mariante.
Na época Dra. Valderês A. Robinson Achutti, minha esposa, estava cursando o último ano do Curso Médico, e no ano seguinte me acompanhou na Residência Médica.
A paciente era uma jovem de 27 anos, auxiliar de enfermagem, que notara os primeiros sintomas há quatro meses. Não conseguíamos enquadrar o caso em nenhuma nosologia comumente conhecida. Material do exame pos-mortem, também enviado aos dr. Davis e Saffir (autoridades mundiais no assunto) confirmou a raridade do caso.
Desta entidade mórbida, este foi considerado como o primeiro caso diagnosticado no Brasil, e foi publicado nos Arquivos Brasileiros de Cardiologia, e na revista Cor et Vasa (Elsevie - Amsterdam).
Mais detalhes relacionados com o título, mas de acesso restrito. (solicitar)
Agradecimentos à família da paciente, e aos co-autores do artigo, mesmo depois de 64 anos passados.

  • Endomyocardial fibrosis remains an important cause of restrictive cardiomyopathy despite the unsolved questions regarding the cause and therapeutic strategies. Worldwide prevalence is estimated at 10 to 12 million in 2008.1 Echocardiography is the standard modality for endomyocardial fibrosis diagnosis. Ventricular endocardial fibrosis with organized thrombus is the hallmark of advanced disease.2

In this case, a 70-year-old male patient was admitted with symptoms of right heart failure. ECG demonstrated atrial fibrillation and right bundle-branch block. Transthoracic, 2-dimensional, and 3-dimensional transesophageal echocardiography evidenced obliteration of the right ventricular (RV) apex, severe right atrial enlargement with a prominent aneurysm of fossa ovalis, and inferior vena cava dilatation (Figure, Movies I and II in the Data Supplement). Myocardial contrast echocardiography revealed marked RV apex and subtle left ventricular apex subendocardial delayed perfusion and a small perfusion defect over the RV endocardium (Figure, Movie III in the Data Supplement). Late gadolinium enhancement cardiac magnetic resonance imaging showed mild RV systolic dysfunction, apical thickening and obliteration, hypoperfusion at rest, and typical late double V enhancement, compatible with subendocardial fibrosis and thrombus (Figure, Movie IV in the Data Supplement). Left ventricular early involvement was demonstrated by the presence of hypoperfusion at rest and late subendocardial enhancement in its apex and apical lateral segment, as well as involvement of the mitral valve (Figure, Movie IV in the Data Supplement).

Growing Support for a Muon Collider
Support for a plan to build the world’s first muon collider is mounting in the US particle physics community, Elizabeth Gibney reports for Nature. At last month’s Snowmass conference, advocates for the idea were even selling muon-themed t-shirts. Muons offer an especially rich vein for particle physics research because understanding their properties could help uphold or disprove the Standard Model, Natalie Wolchover reported for Quanta last year.


The Itsy Bitsy Dream State
New research suggests that jumping spiders experience something like REM sleep and may even dream, reports Betsy Mason for Scientific American. Scientists observed the arachnids twitching slightly while they slept, just like restless kittens or puppies. Studying the sleeping habits of invertebrates like spiders has helped researchers come to understand that sleep probably evolved before animal brains did, as Veronique Greenwood reported for Quanta last year. Previous studies have also hinted that arachnids lead surprisingly complex interior lives. In a Quanta story from 2017, Joshua Sokol wrote about how spiderwebs can function as an extension of a spider’s cognition.

#Professor Luiz Eduardo Robinson Achutti


Lançamento da Exposição Quando um Livro se torna Álbum de Família 

Em 2015, o fotógrafo/antropólogo Luiz Eduardo Robinson Achutti recebeu uma mensagem enigmática em sua rede social: “Você tem a minha história!”. A mensagem havia sido enviada por uma jovem de 20 anos, até então “desconhecida”.

A interpelação, intempestiva, ficou em suspenso. 

Mas insistiu, retornando de tempos em tempos, como nossas lembranças. 
A jovem persistente, Diênnifer, foi retratada por Achutti com 1 ano de idade, no colo de seus pais, enquanto ele fotografava a primeira experiência de coleta seletiva de material reciclado do Brasil.  As fotos eram parte do trabalho de sua dissertação de mestrado que teve lugar na Vila Dique, em Porto Alegre/RS.

Para Diênnifer e seus familiares, os retratos que compõem o livro oriundo da dissertação de Achutti transformaram-se em fotos de família. As fotografias digitais eram um futuro nada previsível. Não chegara a época dos celulares com câmeras e dos selfies em número infinito. Ser fotografado ou revelar uma foto era um luxo. Ainda mais onde o  “lixo” tinha por objetivo transformar-se em renda. E, por que não, em memória.

Diênnifer buscou Achutti mais de duas décadas depois, atualizando um encontro, uma história, uma memória, uma narrativa. Ou fotoetnografia, conceito cunhado pelo fotógrafo quando da elaboração deste trabalho, em que a imagem compõe a narrativa. 
Muitas histórias e memórias foram lembradas posteriormente ao encontro virtual. Histórias individuais e coletivas que se entrecruzam e que se presentificaram neste trabalho. Memórias que contam muitas vidas: do jovem fotógrafo, de um bebê, de um pai, de uma mãe, de trabalhadores, de uma comunidade, de uma cidade, de um país. 
O Museu das Memórias (In)Possíveis, fazendo jus ao seu caráter, acompanhou o reencontro de Achutti com Diênnifer em 2019, razão dessa exposição. Esse (re)encontro não se deu apenas entre os dois, mas com muitos outros que fizeram e começaram a compor outras narrativas e memórias. Diênnifer revelou com seu ato que também tinha a história de Achutti, assim como ela supunha que ele tinha a dela. E, com essa exposição, você soma-se a nós podendo, então, contá-la.

Volcanoes’ Harmful Vaping
Scientists have now determined that the underwater volcanic eruption in Tonga earlier this year delivered an astonishing 160,900 tons of water vapor to the stratosphere — water vapor that could intensify global warming for years to come, reports Harry Baker for Live Science. This year’s Tonga eruption also cracked open some mysteries about Earth’s past volcanic events. Back in 1883, a volcano on the island of Krakatoa erupted and caused worldwide tsunamis — just as the recent Tonga eruption did. This time, however, geophysicists were finally able to learn how volcanic eruptions cause tsunamis on that global scale, as Robin George Andrews reported for Quanta.

You Are Not the Supreme
In 2019, Google announced that they had achieved quantum supremacy with a calculation that no ordinary computer could match. Researchers in China have now shown that an ordinary computer can do it within hours, reports Adrian Cho for Science. Google’s claim was controversial from the start. Researchers at IBM and others rejected that Google had proved true quantum supremacy, as Kevin Hartnett covered for Quanta in 2019.

#UNITED NATIONS

United Nations Secretary-General Antonio Guterres announced this week that he will attend a ceremony marking the 77th anniversary of the world's first atomic bombing in Japan as Russia's assault on Ukraine and tensions in the Middle East and Korea raise the threat of nuclear weapons use to a level not seen since the end of the Cold War. "Today, humanity is just one misunderstanding, one miscalculation away from nuclear annihilation," Guterres warned at the opening of a nuclear non-proliferation treaty meeting in New York.
