From eczema to hay fever, kids with allergic conditions might be on track to develop others down the road, a new study finds. The study, published in the journal Pediatrics, looked at the electronic medical records of nearly 220,000 children in the US who were screened between 1999 and 2020. The results provide evidence for a recognized trend called the allergic march, a natural progression of allergy-related diseases from infancy through childhood, at the largest scale yet.

Eczema in young babies could be a sign that a child will go on to develop more allergies. New research, published Tuesday in the journal Pediatrics, confirms a phenomenon known as the “allergic march” — a pattern that describes the way allergies tend to develop and progress in children, beginning in infancy through age 3.

Yesterday in Pediatrics researchers mined vaccine records of 16,365 US children ages 19 to 35 months in 2019 to determine how many complete the seven common multidose vaccine series given in infancy and early childhood. They found 1 in 6 US children had incomplete vaccine series. Currently the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices recommends several vaccine series, each consisting of 1 to 4 doses, to protect against 15 diseases in the first 2 years of a child's life.

Tattoos are considered to be among the oldest forms of art, dating back thousands of years and practiced by many cultures across human history. Now some researchers believe the next generation of tattoos will be about more than just markings – by helping keep tabs on our health. (Bresnahan, 7/26)
