#Omicron 35 mutaciones
#Lambda 14 mutaciones
#Delta 9 mutaciones
#Mu 9 mutaciones
De todas estas la mas contagiosa es Delta, y tiene 9 mutaciones, tener mas no es sinónimo de ser peor.
Acá una parte de las mutaciones 👇👇👇
Lo único que tenemos que ver es si es mas contagiosa, con eso es suficiente para ser peor
Acá la otra parte de las mutaciones 👇👇👇
Cuando digo es que suficiente para que sea peor con solo ser mas contagiosa es porque aún manteniendo la tasa de letalidad, al infectar mas gente proporcionalmente irán mas al hospital y fallecerían mas personas.

Quand on entend le porte-parole du Gouvernement qualifier le début de la 5ème vague de "fulgurant", je me dis que :
(a) pas grande chose d'apprise après deux ans de pandémie
(b) faire un peu de maths de base, ne leur fera pas de mal

Nous sommes un certain nombre à dire depuis l'été dernier "que nous vivons encore et toujours dans une période de pandémie et qu'il serait une erreur de considérer qu’elle est sur le déclin, que le pire est derrière nous". La lecture est surtout en terme des tendances globales🔽
On disait aussi "ns restons sur une compréhension approximative du #SARSCOV2 au niveau biologique & socio comportementale, qui malgré le travail exceptionnel des scientifiques du monde entier, présente tjs des aspects imprédictibles, qu’il faut accepter avec humilité, patience"🔽

Boas notícias:
🔹Vacinas SEGUEM PROTEGENDO contra as versões da variante #Delta (AY.4.2, "Delta Plus" e outras), as variantes #Lambda, #Mu e A.30
🔹Publicado na @NEJM os dados da @pfizer em crianças de 5-11 anos

Venha conferir esse e mais dados no fio! 🧶👇
Um estudo da Dinamarca🇩🇰 demonstrou que, após 2 meses da dose 2 e em comparação com a linhagem B.1 (D614G), a AY.4.2 teve uma redução de 2,3x nos títulos medianos de neutralização, não sendo mais resistente à neutralização em relação a outras versões circulantes da #Delta
Já a variante B.1.617.2 + E484K mostrou uma redução de 4,2x na neutralização, porém é uma variante com menor predominância do que outras versões da #Delta. Essa redução não é superior ao que vemos com a #Beta a qual sabemos que as vacinas geram proteção medrxiv.org/content/10.110…

Muita gente ficou surpresa com as notícias referentes a C.1.2, uma variante possível aumento na transmissão e com algum escape imunológico anunciada pelo Inst. Nacional de Doenças Transmissíveis da 🇿🇦 e da Plataforma de Inov.e Seq. de Pesq. KwaZulu-Natal

Acompanha 🧶👇
RESUMO:
🔹Variante com características preocupantes, mas que não tem circulação global
🔹Nada nos diz que vacinas não abrangeriam ela
🔹Mais um indicativo de que o vírus está se adaptando
🔹A desigualdade de distr. de 💉 no 🌎 É UM PROBLEMÃO
🔹💉E 😷pelo amor de Deus

Detalhes👇
Não é segredo, nem novidade, que a permanência desse estado de transmissão elevado, que é construído por vários fatores, (baixa cobertura 💉, falta de adesão adequada a medidas como uso de 😷, p.ex), gera um risco de vermos novas variantes surgirem

#COVID19 Une grande difficulté face est de comprendre que cette viralité touche nos modes de vie bien au delà d'une courte période, la plus visible celle des pics. C'est une nouvelle réalité qui doit aller avec une autre pédagogie dans un monde globalisé, interconnecté #Thread
Si nous voulons retrouver de l'apaisement face aux montées des extrémismes, manipulations, un effort d'explication est indispensable pour sortir de NOS certitudes. Le #COVID19 a encore des zones d'ombre, c'est un défi pour la science qui avance à grands pas pour le comprendre /↩️

As atenções voltadas para a #Delta, e precisam estar. A #Delta já é a variante de predominância global, e aqui no 🇧🇷, temos a #Gama até o momento predominante. Será que a #Delta predominaria sobre a #Gama?

Não sabemos, mas pode ter mais "competidoras" nessa história 🧶👇
Ainda em Março/21, eu fiz um fio de um brilhante trabalho de vigilância da @fiocruz mostrando que a #Gama (que nos referíamos como P.1 naquele momento) poderia estar sofrendo adaptações em virtude do seu amplo espalhamento no país

Uma breve revisão de porque uma transmissão acelerada tem relação com um risco aumentado em vermos mais variantes surgirem, e dentre elas, alguma(s) que possa(m) nos preocupar

BREAKING🔔 The 3rd preprint from G2P-Japan - we elucidated the evolution and virological phenotype of #Lambda variant (aka C.37 lineage). Lambda is resistant to vaccine-induced antiviral immunity. Please retweet 1/3
biorxiv.org/content/10.110…
Mutational anaysis showed that a large deletion in the N-terminal domain of the Lambda spike protein (246-253 residues) is responsible for the resiscence to neutralizing antibodies. 2/3
Moreover, #L452Q mutation in Lambda increases viral infectivity, like the case of #L452R mutation, a characteristic of #Delta. Our data suggest that 1) increasing viral infectivity and 2) evading antiviral immunity are crucial for the efficient spread in the human population 3/3

What is Lambda variant?

C.37 - known as Lambda variant is believed to have originated in Peru and deemed “variant of interest” by @WHO June 14.

“There is currently limited evidence available about this variant,” Dr. Alicia Demirjian of PHE told the @BBCNews.

#COVID19 #Lambda
The Lambda strain is puzzling @WHO after spreading to 30 countries in four weeks.

“Lambda has a unique pattern of seven mutations in the spike protein that the virus uses to infect human cells,” Jeff Barrett of British Covid-19 Genomics told Financial Times

#COVID19 #Lambda
While the strain is deemed highly transmissible, the @WHO stresses “further studies are required to validate continued effectiveness of vaccines,” against Lambda strain.

Canadian health officials say as of July 8, 11 cases of the Covid-19 mutation have been reported.

Ich verlange von niemanden komplette soziale Isolation.
Ich persönlich hatte seit Beginn der Pandemie konstant soziale Kontakte.
Nur eben: nur eine Hand voll in Präsenz.
Alle möglichst Einzeln, auch nicht alle in einer Woche.
Damit, falls doch was passiert, alles übersichtlich bleibt.
Zudem Kontakttagebuch. Mein Maximum war 3 Personen über zwei Wochen. Wobei zwei davon ein Bett teilen.
Was auch immer geht: telefonieren. Online spielen. Aber das ist eh meine gängige Kommunikation mit Menschen, die weiter weg wohnen. War ich also schon vor der Pandemie gewohnt.

Un pequeño hilo 🧵 para descansar un poco de la #Deltamanía 🦠😉y seguir explorando el alfabeto griego de Variantes:

👉🏻Hablemos de #LambdaVariant Λ, también llamada #andina por haber sido detectada inicialmente en Perú🇵🇪, y de la q aún sabemos poco
1/10
#VarianteAndina #Lambda Image
🦠Empezando por aclarar q entre más oportunidad le demos al virus de seguir replicándose, y al hacerlo encontrar mutaciones q le dan ventaja (infección, escape, virulencia), seguirá retando nuestras medidas de mitigación:

Así q urge ponerle al virus barreras ➡️: 💉+😷+ 🌬
2/ Image
Esta variante Λ se detectó desde 2020 en Perú🇵🇪,…y ya está presente en al menos 31 países, entre los que está México

Importante mencionar q sabemos menos de las variantes detectadas en regiones donde la secuenciación genómica no es tan amplía…

Preprint (no revisado por pares aún) de nuestro trabajo sobre eficacia de anticuerpos neutralizantes generados por #CoronaVac (75 muestras) frente a variantes #Lambda (C37), #Gamma (P1) y #Alpha (B117) de #SARSCoV2 #Sinovac
📣medrxiv.org/content/10.110…
Variante #Gamma (preocupación) posee 11 mutaciones incluyendo algunas en el sitio de unión al receptor (RBD) asociadas con un incremento en la unión al receptor ACE2 y la infectividad (N501Y) o a la reducción en la eficacia de anticuerpos neutralizantes (K417T and E484K)
Variante #Lambda (interés) tiene un patrón único de 7 mutaciones (Δ246-252, G75V, T76I, L452Q, F490S, D614G, T859N)

I know "serverless" is sometimes called out as a buzzword, but the model #AWS #Lambda introduced quite literally changed my career (and consequently, my life). (Thread)
A few years ago, I started an open source security auditing tool called CloudSploit. It got a lot of users, but many were asking me if I could offer a hosted version as an API (and they were willing to pay for it!).
I had some experience with server side dev, but CloudSploit had unique challenges. It would have to horizontally scale out / back very quickly as it was running these security scans. I built a quick set of services using EC2, but it quickly became expensive and hard to manage.

What are some database engines that works great with serverless architecture?

#database #CodeNewbie #Serverless #javascript
Note to Self: MongoDB can be used with serverless functions by caching the initial connection.
database engines were designed much before the serverless architecture was a thing.

a connection to the database is always persistent. meaning, it lasts for a really long time.
also, there is a limit(imposed by DBaaS provider) on how many connections a database can have at any given timestamp.

a lambda function is invoked every time a client(generally, browsers) creates a connection. this means a new connection to the database as well.
