🆘 Our work over the past few years has shown that COVID-19 in pregnancy is a serious problem that requires serious public health and medical consideration.

Excellent thread on the paper out this week in Nature suggesting COVID mRNA vaccines may support the immune system in responding to cancer ⬇️
I will try to do a tweetorial about this paper when I have more energy but this is really important data. It looks (tentatively, preliminarily) that COVID-19 mRNA vaccines might significantly enhance the effectiveness of cancer immunotherapy (subject to many caveats).

Government shutdown means many CDC experts are skipping a pivotal meeting on infectious disease
An annual conference about infectious diseases is seeing a dramatic attendance decline, in part because Centers for Disease Control and Prevention experts can’t participate.

Before prescribing leucovorin, doctors would first need to determine whether a patient suffered from the deficiency, Dr. Kesselheim said. How they would arrive at that diagnosis short of a risky, expensive spinal tap was not clear, he said.

Indeed, untreated fever in pregnancy is linked to miscarriage, birth defects, and preterm birth. Unmanaged pain in pregnancy is linked to high blood pressure, anxiety, and depression which are all bad for both mom and baby.
So yes, “toughing it out” and avoiding meds in pregnancy is dangerous.

I’m only now watching longer clips of Trump’s autism disinfo presser and… it’s crazier than I realized? He was unable even to say “acetaminophen” or come up with the word “rubella”; cited his feelings as the basis for changes; and said pregs women should “tough it out,” which is actually dangerous

ACOG and all other professional societies continue to affirm the safety of using Tylenol, also known as as acetaminophen or paracetamol, in pregnancy to treat pain and fever during pregnancy.
ACOG reaffirms that acetaminophen is safe for managing pain and fever during pregnancy. No reputable studies support suggestions like those in HHS’s recent announcement linking acetaminophen use in pregnancy to autism; in fact, high-quality studies show no such risk. https://bit.ly/47Wxc59
