An inspiration-off attractor supports the robust and flexible control of breathing

Breathing is a fundamental motor rhythm necessary to sustain life. The rhythm and pattern of breathing arises from the coordination of a rostrocaudally extended ventral respiratory column (VRC) in the medulla. Although recurrent excitation is sufficient for rhythmic bursting in r...

Influenza A virus infection induces immune dysregulation in the placenta and fetus without vertical transmission in nonhuman primates

Influenza A virus (IAV) infection during pregnancy is associated with stillbirth and preterm birth. We hypothesized that maternal IAV infection disrupts placental and fetal immune networks in ways that correlate with disease severity. Pregnant pigtail macaques were inoculated wit...

Predicting Underweight Status in Infants With Cleft Lip and/or Palate in 10 US Children's Hospitals

ObjectiveTo develop and compare models predicting which infants with cleft lip and/or palate (CL/P) will be underweight at 4 months, using multicenter electronic health record data.DesignUsing data from birth to 3 months, we evaluated 63 anthropometric, clinical, healthcare-utili...

Intra-individual variability of urinary non-persistent chemical concentrations during pregnancy in the ECHO Cohort

Studies of prenatal exposure to non-persistent chemicals often assume biomarker measurements from a single urine sample can represent exposure pregnancy. The validity of this assumption depends on biomarker concentration variability across gestation, which is not well-characteriz...

Alzheimer’s disease neuropathological characterization of the dog brain and relationship to biofluid biomarkers and cognitive function

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder affecting more than 55 million people worldwide and is characterized by cognitive decline, amyloid-beta (Aβ) plaques, and neurofibrillary tangles. Although transgenic rodent models have advanced understanding of...

Parental Refusal of the Best Treatment: Nudges and Trust in Pediatrics

More effective and less toxic therapies are welcomed by clinicians and families and are the rationale and raison d'être for well-designed clinical trials. This is especially true for life-threatening diseases like childhood cancer. When parents opt for an existing and good treatm...

Adaptive Behavior Development and Autism Outcomes: A Comparison of Elevated- and Low-Likelihood Cohorts

Children born low-birth-weight (LBW) or with autistic siblings may show differences in their developmental trajectories, including higher rates of autism and lower levels of adaptive behavior skills. Parsing out developmental differences in these groups could help hone screening...
