The incidence and outcome of patients who undergo therapeutic hypothermia (TH) after toxin-induced cardiac arrest (TICA) is not previously described. Our study aimed to describe the incidence, epidemiologic characteristics, and outcomes of patients who experience TICA in a dedicated clinical pathway for post-cardiac arrest care between November 2007 and February 2013. All patients were treated in an evidencebased clinical pathway that included TH. Database and medical records were independently reviewed by investigators to ascertain TICA. TICA was defined as cardiac arrest (CA) directly and immediately caused by a xenobiotic exposure. All patients were enrolled at Carolinas Medical Center, an urban 874-bed teaching hospital that serves as a regional cardiac resuscitation center. All patients were adult victims of cardiac arrest who had obtained return of spontaneous circulation and were enrolled in a clinical pathway for post-cardiac arrest care that included TH. Three hundred eighty-nine patients underwent treatment following CA during the study period and 48 (12 %) were deemed TICA. Patients who suffered TICA were slightly younger, less likely to have an initial shockable rhythm, and less likely to receive bystander CPR as compared to non-toxic cases. TICA accounted for a significant proportion of patients in this study. Additional, larger studies are needed to fully elucidate the optimal role for TH in TICA.
The Formosan subterranean termite, Coptotermes formosanus Shiraki, and the eastern subterranean termite, Reticulitermes flavipes (Kollar) (Isoptera: Rhinotermitidae), are well known for their destruction of human dwellings and flora in the tropics and subtropics. A method to deliver foreign genes into termite cell cultures would provide a controlled environment to facilitate the study of key regulatory functions at the molecular and cellular level. Here a method for the establishment and cryopreservation of primary embryonic termite cell cultures is described. Evidence is presented of viral-mediated gene transfer in these cells and foreign gene expression using a recombinant vesicular stomatitis virus vector.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
