An experimental therapy that cleared Zika virus from the blood of pregnant monkeys did not stop the virus from crossing into the amniotic fluid and infecting the fetus, researchers reported in Nature Communications. Researchers will now modify the antibodies so that they can cross the placental barrier and protect the fetus, said lead author Diogo Magnani.

Today, April 25, is World Malaria Day, and the international health community is renewing its commitment to prevention and treatment through research and drug development. Malaria cases fell by at least 75% in 57 countries from 2000 to 2015.
Columbia University researchers have developed a novel technique to regenerate damaged heart tissue using extracellular vesicles secreted by cardiomyocytes. The findings, reported in the journal Nature Biomedical Engineering, could help scientists develop new treatments for cardiac medical conditions.
Magellan Health's pharmacy benefit management division Magellan Rx reported that its hemophilia management program has resulted in reduced potential waste, with no reports of breakthrough bleeding among patients who had dose reductions.
Researchers found that time of day does not affect the results of cosyntropin (ACTH) stimulation tests in patients with adrenal insufficiency. A single serum cortisol assessment one hour after ACTH administration gives the most accurate results, the authors said, adding that prospective studies of larger populations are needed to confirm their findings.
In nine countries in sub-Saharan Africa, almost 1 in 4 blood donors from 2000 to 2017 tested positive for Plasmodium parasites, according to a review of data from 26 studies. The rate varied by country from zero to 74%.
British researchers analyzed odors from the used socks of children with and without malaria in western Kenya to determine what compounds might be attractive to Anopheles mosquitoes.
