Globuli ab Geburt: Im neuen @derspiegel berichte ich, wie junge Eltern (und Kinder) zur #Homöopathie getrieben werden - teils sogar, wenn sie ihr ablehnend gegenüberstehen. Ab morgen im Kiosk, jetzt schon online: spiegel.de/gesundheit/elt… 1/ 
"Der Patient fühlt sich wohl und empathisch mitgenommen": Auch wissenschaftsaffine Ärzte rechtfertigen den Einsatz als #Placebo. Erhalten Menschen ohne aufgeklärte Einwilligung #Homöopathie, widerspreche es den Grundfesten der modernen Medizinethik, sagt eine Medizinethikerin. 2/
Erstmals distanziert sich der Deutsche #Hebammen-Verband klar von der #Homöopathie: "Es gibt keinerlei Evidenz für diese Methode", Mütter müssten hierüber aufgeklärt werden. In der Geburtshilfe sei lange nur mit Erfahrungswissen gearbeitet worden - das solle sich nun ändern. 3/
Mega Thread - The Childhood Vaccine Placebo Myth
Is a true saline placebo used w/ the 💉’s on the childhood schedule?
All evidence I’ve provided is directly from the manufacturers insert or safety reports. This is not my opinion so take it up with FDA & Pharma if you’re mad.

In the @COMPASSPathway trial the 25mg vs 1mg (=placebo) #Psilocybin difference is not only significant statistically, but also clinically. On the MADRS the 'minimal important difference' is ~3-6 points (tinyurl.com/5apzv8h8), the 25mg dose meets this criteria (more context 👇)
The 'minimal important difference' sounds like a low bar to cross, but actually most #antidepressants fail to do so relative to #placebo, tinyurl.com/yut6xyhd - thank you @PloederlM for your work on this, would love to hear your take on this trial!
Lack of blinding remains an issue, but the dose-response relationship should alleviate this concern. As I argued before, #psychedelics macrodose trials most likely will always lack blinding due to obvious drug effects, it is the nature of the intervention.

Despite the importance of #blinding in medical research, most trials don't assess blinding integrity, partially because there is no method to adjust trial results for blinding integrity... until now! New preprint with implications for #microdose and #psychedelic research 🧪🧵👇
First, we define activated expectancy bias (AEB), which is an uneven distribution of expectancy effects between treatment arms due to patients recognizing their treatment allocation. AEB can be viewed as residual expectancy bias not eliminated by the trial’s blinding procedure.
The main idea behind AEB is that if treatment allocation can be deduced by participants, then, treatment expectancy can bias the outcomes in the same manner as it biases non-blinded trials, for example as in open-label trials.

@ASlavitt , can you get some clarity on a group of people that is small in number regarding #BoosterShots . I'm a #Pfizervaccine trial participant who was vaccinated fully by Sept 2020, and now I'm a booster trial participant. I'm pretty sure I'm in placebo group for booster

Is placebo effect as powerful as some suggest?
Not really.
But it's surprisingly consistent, & that has important implications in medicine.

Even then, the importance of suggestion/placebos/bedside manner/whatever you call it was known to be tremendously important.

Most of us who have prescribed antidepressants for thousands of patients have heard hundreds of them report transformed lives. “It is as if I walked out of a dark room into sunlight” “All of a sudden I can experience pleasure again”
But perhaps the effectiveness is an illusion. The improvement of patients taking #placebo is barely better than that for those taking antidepressants.

It took a while to digest the details of over 600 pages, but here is my review and comparative analysis of the #ACTT2 trial that compared #baricitinib vs. #placebo among patients receiving #remdesivir for #COVID19!

The idea of using #baricitinib (aka Bari) for #COVID19 is in this commentary in .@TheLancet from Feb. when Peter Richardson & Co working .@benevolent_ai .@ucl searched drugs and noted that #bari could block inflammation & viral endocytosis.
