Brain & AgingFeeling Fine in Pregnancy Was No Shield Against Dirty Air's Link to Postpartum Depression
Among 475 Mexico City mothers, each 5 microgram per cubic meter rise in fine-particle pollution during pregnancy tracked with 2.67 times the risk of depression symptoms that first appeared after birth. The link was stronger in women who reported little stress.
InvestigationsIn Cancer Alley, the Most Polluted Air Came With More Than Four Times the Odds of a Newborn Heart Defect
Among Louisiana mothers without private insurance, the heaviest modeled industrial air toxics tracked with 4.29 times the odds of a baby born with a heart defect. The scientist who led the work says Tulane gagged her pollution research.
Brain & AgingA Protein That Should Surge Before Birth Went Flat in Pregnancies Later Linked to Childhood ADHD
Each standard-deviation drop in third-trimester placental growth factor came with 2.6 times the odds of a later ADHD diagnosis, and the signal held even after researchers accounted for preeclampsia, growth restriction, and early preterm birth.
Metabolic & WeightForever Chemicals, Pregnancy, and the Vitamin That Might Decide Who Gets Hurt
Early-pregnancy PFAS tracked with gestational diabetes in a 420-woman China cohort, but almost entirely in mothers already low on vitamin D. A 5,229-pregnancy US analysis found no added risk at all. The gap between them may come down to one cheap blood test.
Brain & AgingThey Measured the Forever Chemicals in the Umbilical Cord Itself. The Babies With the Most Scored Lower at Two.
Scientists skipped the usual stand-in and measured the forever chemicals in the umbilical cord blood itself. By age two, the babies carrying more of them scored lower on communication and motor development, and the companies that made these chemicals knew the risk for decades.
InvestigationsMonths Before Officials Told Pregnant Women the COVID Shot Was Safe, Fauci Privately Flagged a Theoretical First-Trimester Miscarriage Risk
Senators Ron Johnson and Rand Paul pulled the first messages off Fauci's government iPhone: a January 2021 chain in which he privately flagged a theoretical first-trimester miscarriage risk, months before official guidance told pregnant women the shot carried no such concern.
InvestigationsPregnant Women's Blood Pressure Registers Every Smoke Day. A Federal Rule Lets States Erase Those Days From the Record.
On heavy smoke days, adults' systolic pressure ran nearly 4 mmHg higher; across eight southwestern states, gestational smoke exposure raised the odds of gestational hypertension 12 percent. Since 2016, regulators have won EPA approval to erase wildfire smoke from the Clean Air Act record in more tha
Brain & AgingYour First Pregnancy Rewires the Brain for One Baby. Your Second Rewires It for the Chaos of Two.
Amsterdam researchers scanned 110 women and found each pregnancy leaves its own mark, and the brain changes tied to maternal depression showed up months earlier the second time around.
CancerPregnancy Stations Killer T Cells in the Milk Ducts, and a Decade Later They Haven't Left
Melbourne researchers found that pregnancy stations killer T cells in the milk ducts, where they persist for at least a decade and track with better breast cancer outcomes. Now the race is on to summon them with a hormone shot instead of a pregnancy.
