Evidence strengthens autism’s link to maternal obesity, diabetes

In a study published online in Autism Research, researchers from the Division of Biostatistics and Epidemiology show they can use electronic medical records and birth information to verify and strengthen an already suspected link between autistic children and pregnant mothers with obesity and diabetes. According to study data, pregnant mothers with obesity or gestational diabetes were 1.5 times more likely to have a child with an autism spectrum disorder (ASD) compared to mothers of children without developmental disorders. The increased risk of ASD for pregnant mothers with both obesity and gestational diabetes was two-fold.

“Without placing any burden on study participants or the costs of developing an epidemiologic study from scratch, we can use the vast amounts of data already collected for clinical purposes to conduct broad population-based studies on this link to autism. We are very excited about the future studies we can do with this ability,” says Katherine Bowers, PhD, MPH, the study’s senior author.

Exposure to high levels of small particle air pollution linked to higher preterm birth risk

Cincinnati Children’s researchers find that exposure to high levels of small particle air pollution is associated with an increased risk of preterm birth, according to a new study published online in the journal Environmental Health. “We estimate that decreasing the amount of particulate matter in the air below the EPA’s standard threshold could decrease preterm birth in women exposed to high levels of small particulates by about 17 percent, which corresponds to a 2.22 percent decrease in the preterm birth rate in the population as a whole,” says physician-researcher Emily DeFranco, DO, with the Center for the Prevention of Preterm Birth.

Preterm birth rates were higher among mothers exposed to high levels of airborne particle pollution above the EPA standard, as well as among mothers 40 or older, black mothers, and women with no prenatal care or with lower education level.

Molecule Identified that Appears to Fuel Genetic Disease

Published in Stem Cell Reports, Cincinnati Children’s researchers report identifying a molecular target and experimental treatment strategy for DNA repair defects behind Fanconi anemia.

Newly Discovered Cell Type Helps Explain Cause of Dangerous Food Allergies

A study led by researchers in the Division of Allergy and Immunology. reports findings that offer insight into new therapeutic strategies and diagnostics for severe food allergies triggered by immunoglobin E (IgE). The study, published in the journal Immunity, reveals the discovery of IL-9-producing mucosal mast (MM9) cells that produce large amounts of an inflammatory protein, interleukin 9 (IL-9), known to amplify anaphylactic shock in response to certain foods. “Our study suggests that although you need to have some level of IgE to trigger a food allergy response, you also have to produce MMC9 cells to get a severe response and anaphylaxis,” says Yui-Hsi Wang, PhD, the study’s co-first author. “Without these cells you will not get severe food allergies.”

The Untold Story of a New Asthma Drug

When the FDA approved the drug mepolizumab on November 4th to help treat severe asthma, it was a blip on the radar screen of health industry news. The medication targets a subset of asthma patients (ages 12 and up) whose current drug regimens are insufficient to control their condition.

Absent from official press announcements about mepolizumab’s approval on Nov. 4 are the many years of research and testing by countless physicians and scientists at institutions around the world. Cincinnati Children’s and its Division of Allergy and Immunology were key parts to this effort.

Genetic Test Could Help Doctors Time Delicate Births

Doctors may soon have a new tool to help them time births in the case of delicate, pre-mature babies. A study led by researchers at Cincinnati Children’s Perinatal Institute have identified a way to test RNA and specific genetic signatures in amniotic fluid to see whether fetal lungs – and potentially other organs – are mature enough for a safe and viable delivery. “This will allow pediatricians and neonatologists to prepare for the various neonatal morbidities these preterm infants may face, and allow obstetricians to better weigh risks to the baby when making decisions about preterm delivery,” says Beena Kamath-Rayne, MD, MPH, one of the study’s lead authors. The findings are published in BMC Medical Genomics.
