Measles Could Go “Viral” When America was great and measles was common, the US Public Health Service published a weekly report on infections like cholera, plague, and measles. Here is a photo of a 1938 measles report. This is what will happen if immunization rates fall below herd immunity levels.

In 2023, guns continued to be the top cause of death for children. More than cancer. More than car accidents. More than sudden unexplained infant death (SUID). Gun deaths are 100% preventable.

Measles is a vaccine preventable disease. My condolences to the family bearing this tragic loss.

Hey! Along with millions of other people across the US, this is MY family’s fall 2025 flu vaccine we are putting at risk here! www.nytimes.com/2025/02/26/u...

Best to prevent obesity in children. We are not there yet. In the meantime, this placebo controlled trial of a GLP1 receptor agonist is good news. Nice summary below.

Indirect (facility and admin) costs are real. For 70 years, the US biomedical research enterprise has been structured on recovery of these institutional expenditures. Reduction of indirect costs recovery to 15% will cripple US biomedical research for decades. www.science.org/content/arti...

Great advice herein. As a pediatric gastroenterologist, I can especially endorse: "trust your gut"!

It is easy to understand the benefit of a new cure for cancer. It feels like a miracle. Vaccines are different. We will never know if one of us, or one of our loved ones, has been saved from death or severe illness by a vaccine. That's prevention. And it is no less a miracle than a cure for cancer.

According to US News, I am still a practicing doc, living in Gainesville FL, practicing in Columbus OH, and holding hospital privileges in nearby West Virginia hospitals. I remain on insurance rolls and appointments are available! Other than living in Gainesville, none of this is true!

Recruit more physicians and scientists to the clean air of the BlueSky, friends!

It was the CDC's communications that alerted the medical community to the dramatic national increase in M. pneumonia infections this fall. These alerts appropriately reshaped clinicians' approach to management of children and adults with respiratory symptoms. www.sciencefriday.com/segments/wal...

Pediatric gastroenterology colleagues, take note. Fascinating to think of the future of non-invasive ways to monitor our IBD patients for relapse - kind of like a DAILY calprotectin!

This seems to be a very practical resource. Love it. Important as the body of evidence linking consumption of ultra processed foods to adverse health outcomes is increasingly robust.

Microbiome analysis from over 21,000 vegans, vegetarians, and omnivores reveals microbe signatures associated with each diet type. Microbes found in diets rich in plant-based foods were associated with favorable markers of cardiometabolic health! www.nature.com/articles/s41...

Whooping cough (pertussis) cases 5x higher this year than last! A combo of factors: * normal cyclical swings in infexns * pandemic changes in behavior (masking, distancing), now w/ rebound in cases - although we’re seeing decreases in RSV this year so I’m skeptical * decreased vaxx rates 🧪🩺🛟

Whooping cough, a vaccine preventable disease, on the rise in 2024.

Latest from the NRMP: percentage of pediatric gastroenterology fellowship positions filled this year (81.1%) is modestly improved over last year, still below historical highs of upper 90s.

Great to see the American Board of Pediatrics @abpeds.bsky.social here!

See my adjacent post for reminder about measles in the US. CDC Director Cohen is right in her warnings… @statnews.bsky.social

The measles vaccine is highly effective in preventing illness, reducing hospitalizations, and preventing death. See graphic from N Engl J Med 2019: 381: 349. Nearly 0.5 million US cases/yr before vaccination. "Those who cannot remember the past are condemned to repeat it." - G. Santayana (1905)

See retractions in 4 year old with "walking pneumonia". Walking pneumonia often = Mycoplasma pneumoniae pneumonia. Not always.

Fun to return to Nationwide Children’s Hospital yesterday to hear an update from NIDDK Director, Dr. Griffen Rodgers, as he gave the the annual John Barnard, MD Lecture.
