Effects of Overweight and Obesity in Pregnancy on Health of the Offspring.

Endocrinol Metab Clin North Am 2020 Jun 16;49(2):251-263. Epub 2020 Apr 16.

Mayo Clinic, 200 First Street Southwest, Rochester, MN 59505, USA.

Overweight and obesity in pregnancy confer a wide range of risks on mother, fetus, and offspring throughout their lives. In addition to compounding many common pregnancy complications, including both iatrogenic preterm delivery and cesarean delivery, obesity is associated with multiple fetal anomalies, metabolic sequelae including diabetes and obesity, allergy and asthma, attention-deficit disorder, and likely many other challenges for the offspring. As targeted interventions are being developed, encouraging solid nutrition and exercise in women of childbearing age may stave off risks and mitigate obesity in the next generation. Read More

Maternal diesel particle exposure promotes offspring asthma through NK cell-derived granzyme B.

J Clin Invest 2020 May 14. Epub 2020 May 14.

Division of Allergy and Clinical Immunology, National Jewish Health, Denver, United States of America.

Mothers living near high-traffic roads before or during pregnancy have increased odds of having children with asthma. Mechanisms are unknown. Using a mouse model, here we showed that maternal exposure to diesel exhaust particles (DEP) predisposed offspring to allergic airway disease/AAD (murine counterpart of human asthma) through programming of their NK cells; predisposition to AAD did not develop in 'DEP' pups that lacked NK cells and was induced in normal pups receiving NK cells from wild type 'DEP' pups.

Vitamin D insufficiency during pregnancy is widespread. The effects of active vitamin D on the human placenta in vivo are unknown. We test the hypotheses that 25(OH) D sufficiency (arbitrarily defined as 25(OH)D ≥ 32 ng/mL) modulates placental structure and function in vivo in a population of women whose offspring are at risk for childhood asthma, and that placental pathology is more common in offspring that evolve asthma at age three.

Establishing a high microbial load maternal-offspring asthma model in adult mice.

Int Immunopharmacol 2020 Apr 3;83:106453. Epub 2020 Apr 3.

Department of Respiratory and Critical Care Medicine, The Fifth Affiliated Hospital of Sun Yat-Sen University, Zhuhai, Guangdong 519000, PR China. Electronic address:

Background: Although it is widely accepted that the "hygiene hypothesis" explains the increased incidence of asthma, the lack of suitable animal models hinders further in-depth studies of the underlying molecular immune mechanisms. Therefore, we aimed to develop a robust mouse asthma model to investigate the role of bacteria in preventing asthma.

Methods: BALB/c female mice were fed a mixture of eight common bacterial lysates (BL; Broncho-Vaxom®) and a commercial probiotic (Bifidobacterium tetravaccine tablets) at different concentrations before and during pregnancy to simulate different microbial load levels. Read More

Mediation of firearm violence and preterm birth by pregnancy complications and health behaviors: Addressing structural and post-exposure confounding.

Am J Epidemiol 2020 Mar 27. Epub 2020 Mar 27.

Division of Epidemiology & Biostatistics, School of Public Health, University of California, Berkeley, Berkeley, California.

Firearm violence may indirectly affect health among pregnant women living in neighborhoods where it is endemic. We used birth, death, emergency department, and hospitalization data from California from 2007-2011 to estimate the association between living in a neighborhood with high firearm violence and preterm delivery, and assessed whether there was mediation by diagnoses of pregnancy complications and health behaviors during pregnancy. We used an ensemble machine learning algorithm to predict the propensity for neighborhoods to be classified as high firearm violence. Read More

Association Between Maternal Exposure to Magnetic Field Nonionizing Radiation During Pregnancy and Risk of Attention-Deficit/Hyperactivity Disorder in Offspring in a Longitudinal Birth Cohort.

JAMA Netw Open 2020 Mar 2;3(3):e201417. Epub 2020 Mar 2.

Division of Research, Kaiser Foundation Research Institute, Kaiser Permanente, Oakland, California.

Importance: An association between maternal exposure to magnetic field (MF) nonionizing radiation during pregnancy and the risk of attention-deficit/hyperactivity disorder (ADHD) has been reported in both animal and human studies.

Objectives: To determine whether maternal exposure to high levels of MF nonionizing radiation is associated with an increased risk of ADHD in offspring by using more accurate measurements of MF nonionizing radiation levels and physician-diagnosed ADHD, rather than self-reports, and to determine whether the association differs for the subtypes of ADHD with or without immune-related comorbidities.

Design, Setting, And Participants: A longitudinal birth cohort study was conducted at Kaiser Permanente Northern California among 1482 mother-child pairs whose mothers were participants of an existing birth cohort and whose level of exposure to MF nonionizing radiation was captured during pregnancy in 2 studies conducted from October 1, 1996, to October 31, 1998, and from May 1, 2006, to February 29, 2012.
