Our latest paper describing #universal #CoV vaccine that can protect against #MERSCoV and #SARSCoV is now out⁩ in #preprint@YaleMed⁩ ⁦

Short thread 👇🏼

“Vaccine-mediated protection against merbecovirus and sarbecovirus challenge in mice” biorxiv.org/content/10.110…
We were interested in developing vaccination strategies against highly pathogenic human #coronaviruses with epidemic potential. Our previous studies, and those of others, defined the #RBD as a major target of neutralizing antibodies.
We therefore looked to #ferritin nanoparticles as a scaffold to display genetically divergent RBDs from both Group 2c merbecoviruses (#MERSCoV) and Group 2b sarbecoviruses (#SARSCoV , #SARSlike viruses, and #SARSCoV2). Our vaccines elicited broad binding antibodies in mice.

„Ambitionierte Athleten vernachlässigen oft die bei einem Infekt nötige körperliche Schonung, was im Verlauf wiederholt zu der Frage nach einer möglichen Myokarditis führt.“ ⬇️
„Wer bei einer #COVID19 Infektion durchpowert, scheint ein deutlich höheres Risiko zu haben, Long COVID
zu bekommen", so Professor Danny Altmann vom Imperial College London. Auch Menschen mit milderen Symptomen können #LongCovid entwickeln, vor allem wenn sie sich nicht ausruhen, was erklären könnte, warum so viele Betroffene jung und gesund sind.“

En ik word nog steeds bozer, om niet te zeggen, woedend, @ArmandGirbes, want het is niet zo dat we als artsen bij alles wat we niet weten, lijdzaam afwachten totdat de heilige Cochrane er een antwoord op heeft. Integendeel.

Je bent nota bene hoogleraar intensive care en klinisch farmacoloog. Dus ik mag enig kritisch denkvermogen verwachten.

En dus wijs ik je op de definitie voor evidence based medicine zelf:

pubmed.ncbi.nlm.nih.gov/26934549/
'Evidence-based medicine is the integration of individual clinical expertise with the best available research evidence.'

Mijn 'clinicial expertise' vereiste dat ik het gezicht van mensen moet kunnen zien, en mensen dat van mij.

Gerade wieder viel Interesse an #Schnelltesten & neuen #SARSCoV2 #COVID19 Varianten: Zeigt, wie wichtig kontinuierliche Validierung von Diagnostika weiterhin bleibt. Unser Zentrum @gcevd @Hopitaux_unige führt seit 2020 kontinuierlich dazu Studien durch zusammen mit @FINDdx & @WHO
Diagnostik ist ein vernachlässigter Aspekt in der Kontrolle neuartiger Krankheiten, Studien dazu haben nur geringe Chance hoch publiziert zu werden, Drittmittel dafür gering, Expertise, die man für gute Diagnostik braucht, wird unterschätzt & fehlt oft massiv in Expertenpanels
Dabei ist Diagnostik DER Schlüssel, Fälle einer neuen Infektionskrankheit sofort zuverlässig zu erkennen. Wie fragil die diagnostische Kapazität schnell wird, hat sich Anfang 2020 gezeigt, asl plötzlich extrem viele Proben getestet werden mussten, aber es an allem fehlte.

Hohe Zahlen an Neu- und Reinfektionen durch #omicron werden sich nicht verhindern lassen. Diese werden zwangsläufig in 15-30 % zu
#LongCovid #LongCovidKids führen.
Orientierend an #SARSCoV müssen wir in bis zu 30 % mit Chronifizierungen im Sinne von #MECFS rechnen.
Dies ist verbunden mit einem hohen Anteil an Erwerbsunfähigkeiten. Monate- oder lebenslang. Behinderung führt zu Armut!
Unter der Annahme dieser Fakten gibt es aktuell kein besser angelegtes Geld als in Therapiestudien zu #LongCovid investiertes. @BMBF_Bund @BMG_Bund
Es gibt keine wirksame Prävention von #LongCovid. Bisher ist unklar, wie häufig wir es bei Geimpften/Geboosterten sehen werden. Es gibt für Long COVID nur ein Konzept:
Alles in die Entwicklung einer oder mehrerer wirksamen Therapien investieren!

Rutte and Dutch parliament continue to cover up their crimes against humanity with scandal. They cower behind incompetence to mask malice and absolve themselves from responsibility, shifting blame to the people. We need to put to words the montrosity happening in real time 🧵
The hospitals and intensive care capacity has already been reached; they are by definition at #codezwart and will soon be rationing care, if not already behind closed doors. 🧵2

Dutch Parliament is now steering towards excess mortality; thanks to delayed and inconsistent reporting, they can hide actual deaths due to #covid19. An extra 3,000 deaths from this wave alone, half of which could have been prevented with timely booster shots, is acceptable. 🧵3 ImageImage

Este artículo plantea 2 preguntas:
1. ¿Se notificaron brotes similares de neumonía atípica, incluso en un nivel menor, entre el SARS del 2004 y el COVID-19 en 2019/20 en China?
2. De dónde provenía el beta-coronavirus más estrechamente relacionado hasta la fecha ➡️
con el #SARSCoV2 a nivel de secuencia del genoma de la cepa RaTG13 (CoV4991), que se tomó una muestra de un murciélago de herradura en la provincia de Yunnan?.

Análisis filogenético y de recombinación de virus similares al #SARSCoV2
La mayoría de los análisis se centra en RdRp como un gen conservado en una región que se cree que es menos propensa a la recombinación. Sin embargo, el análisis de identidad de nucleótidos y la filogenia ➡️
específica de genes revelan una recombinación desenfrenada entre los #SARSrCoV. La recombinación no solo puede dar como resultado una incongruencia filogenética, sino que también puede confundir las relaciones evolutivas cuando los eventos de recombinación ➡️
no se identifican fácilmente. En el caso de los virus similares al #SARSCoV2 como el #RmYN02 y #RacCS203, un árbol RdRp no sugiere una relación particularmente estrecha. Sin embargo, comparten un evento de recombinación de "S", lo que sugiere un ancestro común muy reciente. ➡️ Image

When were the first human #coronaviruses (CoVs) discovered and studied?

How were these viruses associated with human #disease?

It's time to learn our history about human CoVs, and the scientists and volunteers that allowed us to identify this new group of viruses.

A THREAD.
Mid-sixties: HCoV-229E and HCoV-OC43 were identified.

2. McIntosh et al. (1967)
3. Tyrrell et al. (1965).

Healthy HUMAN volunteers were infected to demonstrate that 229E and OC43 resulted in a common cold.

The @SwissScience_TF proposes to halve confirmed #SARSCoV2 cases every two weeks to reach less than 500 cases in January. What does this mean regarding the reproduction number? A thread about doubling times and half-lifes of #SARSCoV. (1/n)
The figure (in German) shows the relationship between the reproduction number and the time in which the number of new #SARSCoV infections double (red) and reduce by 50% (green). (2/n)
In early March 2020, the virus spread uncontrolled in Switzerland with a reproduction number of 2.8 which corresponds to a doubling time of 3 days. (3/n)

A short thread on PCR #SARSCoV2 There’s been a lot of discussion recently about the use of PCR (Polymerase Chain Reaction) for the diagnosis of #SARSCoV2 infection, and the interpretation of its results. 1/n
Hopefully, this thread can provide some background and context for those who are not familiar with the technique. PCR has become the cornerstone of molecular diagnostics in virology, and is, simply put, a technique for amplifying DNA (and indirectly RNA). 2/n
It can be used for straightforward detection purposes i.e. to provide a qualitative yes/no answer. Alternatively, it can be used to provide a quantitative result, i.e. to tell us how much of something is present. 3/n

PROBLEMÁTICA ACTUAL ❗❗🗣️ Yo, @EchinusMelo soy becaria posdoctoral en el extranjero por @Conacyt_MX . Nuestro compromiso es cumplir con actividades en programas de posgrado nacionales. Para que se libere nuestra beca debemos probar que regresamos al país y que trabajamos 6 meses
Cómo lo comprobamos? 1) Nos piden copia de TODO el pasaporte o un registro de entradas y salidas por migración. Y debemos probar ingresos recibidos por 6 meses, sin importar si lo expide @Uber o @LaCasaDeTonoMx (100% fans).
Debido a la pandemia/cuarentena, pedimos a @Conacyt_MX que nos diera la liberación de beca al terminar nuestra estancia y que no nos pudiera estos comprobantes que, a nuestro parecer, son inútiles si quieren evitar la famosa #FugaDeCerebros
