A new study published today -- World Prematurity Day -- in the American Journal of Obstetrics & Gynecology provides additional support for treatment with vaginal progesterone to reduce the risk of preterm birth, neonatal complications and infant death in pregnant women with a short cervix. A shortened cervix is the most powerful predictor of preterm birth.
While simulation platforms have been used to train surgeons before they enter an actual operating room (OR), few studies have evaluated how well trainees transfer those skills from the simulator to the OR. Now, a study led by Rensselaer Polytechnic Institute that used noninvasive brain imaging to evaluate brain activity has found that simulator-trained medical students successfully transferred those skills to operating on cadavers and were faster than peers who had no simulator training.
A new discovery may one day lead to natural anticavity products, researchers report. The scientists from West China School of Stomatology and Academic Centre for Dentistry Amsterdam have figured out the main active ingredient of Galla Chinensis, a natural herb, and further improved its anti-caries efficacy. The finding is published in The Open Dentistry Journal.
Scientists have elucidated the Zika burden in a Brazilian metropolis. Their data indicate: the outbreak may be coming to an end and further outbreaks in the region seem unlikely. The study has also provided new evidence supporting the link between Zika infection during pregnancy and malformations in newborns. A third finding is important with regard to intervention measures: Zika virus infection predominantly affects poor regions.
Patients experience pain and discomfort during active orthodontic treatment with fixed appliances. It can vary from person to person and is influenced by certain factors such as age, gender, previous pain experiences, stress or anxiety, and type of appliance.
General practitioners trained in compression ultrasonography accurately diagnose deep vein thrombosis.
Pam Silver's research team reports in Molecular Cell two new types of kill switches that address these challenges. The new kill switches are self-sufficient and highly stable in bacterial populations that evolve, and they last over many generations. They can ensure that only bacteria with intact synthetic gene circuits survive, or confine bacteria to a target environment at 37°C (body temperature) while inducing them to die at lower temperatures, as demonstrated during bacterial exit from a mouse intestinal tract.
Birth defects in babies born infected with Zika virus remain a major health concern. Now, scientists suggest the possibility that some women in high-risk Zika regions may already be protected and not know it. New research in PLOS Pathogens on Nov. 16, performed in mice, shows women who develop symptom-free Zika infections may be able to acquire immunity that would protect them from future infections and their offspring in a future pregnancy.
Researchers at The University of Texas at Austin are developing a new tool for liquid biopsy that can detect RNA biomarkers from cancer cells in a patient's blood much more accurately and completely than other existing methods. This could soon provide doctors with a more complete picture of an individual's disease, improving their chances of finding the best treatment, while also sparing patients the pain, inconvenience and long wait times associated with surgical biopsies.
A new computational model of heart tissue allows researchers to estimate the probability of rare heartbeat irregularities that can cause sudden cardiac death. The model, developed by Mark Walker and colleagues from Johns Hopkins University, Baltimore, and IBM Research, Yorktown Heights, N.Y., is presented in PLOS Computational Biology.
