Placental transport mechanism could guide safer biologic medicines during pregnancy

Biologic medicines have transformed the treatment of cancer, autoimmune diseases, migraine, inflammatory disorders and many other conditions. Yet their growing use among women of reproductive age constitutes a major clinical challenge because therapeutic IgG antibodies are actively transported across the placenta to the developing fetus. Evidence supporting the safe use of such therapeutics during pregnancy remains limited.

For the tiniest patients, new tech brings clearer MRI images

Some of medicine’s smallest patients can present its biggest imaging challenges. An infant’s heart can be as small as a walnut, beating rapidly inside a body that will change dramatically as the child grows. Yet much of the equipment used in MRI comes in standard sizes better suited to adult bodies, and customized versions can cost thousands of dollars and take months or even years to manufacture.

Microplastics cross placenta-like barrier and disrupt key pregnancy hormones in new cell model study

Tiny, near-invisible fragments of plastic shed from the products we use every day through sunlight and mechanical wear have been quietly working their way deep into the human body. Microplastics have already been found in the human brain, semen and even the placenta. A recent study investigated how these micro- and nanoplastics (MNPs) might move through the placenta and whether they affect a baby’s development.
