Imaging tech produces real-time 3D maps of uterine contractions during labor WUSTLmedschool NatureComms
"There are all kinds of obstetrics and gynecological conditions that are associated with uterine contractions, but we don't have very accurate ways of measuring them," said senior author Yong Wang, Ph.D., an associate professor of obstetrics & gynecology, of electrical & systems engineering, of radiology, and of biomedical engineering.
Researchers at Washington University School of Medicine in St. Louis have developed a new imaging method to produce detailed 3D maps of uterine contractions in real time. The technology could help define the progression of healthy labor and identify when problems may be developing, such as in preterm labor or labor arrest. Shown is a video clip of the left and right view of the real-time progression of a single uterine contraction during normal labor.
The study included patients who were giving birth for the first time and some who had given birth before. The researchers found that patients who had not given birth before had longer contractions with more variation compared with patients who previously had given birth. This is indicative of a possible memory effect of the uterus. In those who previously have given birth, the uterus appears to remember its past labor experience and has more efficient and productive contractions.

Researchers identify novel genes that may increase risk for schizophreniaResearchers have identified two previously unknown genes linked to schizophrenia and newly implicated a third gene as carrying risk for both schizophrenia and autism. Led by the Icahn School of Medicine at Mount Sinai, the multi-center study further demonstrated that the schizophrenia risk conferred by these rare damaging variants is conserved across ethnicities. The study may also point to new therapeutics.
