Stroke Telemedicine for Arizona Rural Residents, the Legacy Telestroke Study.

Background: Efficacy of telemedicine for stroke was first established by the Stroke Team Remote Evaluation Using a Digital Observation Camera (STRokE DOC) trials in California and Arizona. Following these randomized controlled trials, the Stroke Telemedicine for Arizona Rural Residents (STARR) network was the first telestroke network to be established in Arizona. It consisted of a 7 spoke 1 hub telestroke system, and it was designed to serve rural, remote, or neurologically underserved communities.

Chromatic Bacteria - A Broad Host-Range Plasmid and Chromosomal Insertion Toolbox for Fluorescent Protein Expression in Bacteria.

Differential fluorescent labeling of bacteria has become instrumental for many aspects of microbiological research, such as the study of biofilm formation, bacterial individuality, evolution, and bacterial behavior in complex environments. We designed a variety of plasmids, each bearing one of eight unique, constitutively expressed fluorescent protein genes in conjunction with one of four different antibiotic resistance combinations. The fluorophores mTagBFP2, mTurquoise2, sGFP2, mClover3, sYFP2, mOrange2, mScarlet-I, and mCardinal, encoding for blue, cyan, green, green-yellow, yellow, orange, red, and far-red fluorescent proteins, respectively, were combined with selectable markers conferring tetracycline, gentamicin, kanamycin, and/or chloramphenicol resistance.

Comparison of Stroke Outcomes of Hub and Spoke Hospital Treated Patients in Mayo Clinic Telestroke Program.

Purpose: To examine telemedicine as it applies to acute ischemic stroke care at a spoke hospital and the effect on patient outcomes, including the timeliness of response, quality of care, safety, morbidity, and mortality when compared to standard hub hospital stroke center care.

Methods: Retrospective review of prospectively entered quality/performance stroke/telestroke patient catalog data were completed for 1000 adult patients who presented with an acute ischemic stroke to the Mayo Clinic Hospitals (500 patients) or to one of thirteen Mayo Clinic affiliated telestroke spoke hospitals in the regions (500 patients). The primary outcome of interest was the percentage of accurate decision making for eligibility of IV alteplase administration assessed by blinded adjudication and the secondary outcomes pertained to complications, discharge parameters, and standard quality metrics.
