ART Embryo Transfers to Gestational Carriers Increased Chances of Pregnancy
NEW ORLEANS — Assisted reproductive technology (ART) cycles with an embryo transfer to a gestational carrier increased the likelihood of pregnancy and live birth, an analysis of national data from 2014 to 2020 showed. In over 1 million ART cycles with an embryo transfer, those with a gestational carrier were more likely to result in […]
FDA Advisors Back Fecal Microbiome Treatment for Recurrent C. Diff
An FDA advisory board recommended the agency approve a fecal microbiota transfer (FMT) product for recurrent Clostridium difficile infections. By a vote of 13-4 on Thursday, the Vaccines and Related Biological Products Advisory Committee (VRBPAC), said RBX2660 was effective for treating patients with recurrent C. diff infections who failed first-line antimicrobial therapy. Safety landed in […]
Longer Ischemia Time Not Tied to Higher Complication Rate in Free-Tissue Transfer
DALLAS – Prolonged ischemic time for free-tissue transfer in head and neck (H&N) reconstruction was not linked with intraoperative or postoperative complications, a researcher reported here. Among patients in the quartile of fastest times — a mean of 104 minutes of ischemic time in the free flap surgery — the postop complication rate was 21.3%, […]
Research finds key advances towards reducing the cost of plant improvement
Crop improvement often involves the transfer of genetic material from one organism to another to produce a valuable trait. Some major examples of crops with these so-called “transgenes” include disease-resistant cotton and beta-carotene-enhanced golden rice. However, when foreign DNA is introduced into a host organism, a natural defensive response in plants is to repress or […]
