TL;DR: Among patients with acute stroke who had last been known to be well 6 to 24 hours earlier and who had a mismatch between clinical deficit and infarct, outcomes for disability at 90 days were better with thrombectomy plus standard care than with standard care alone.
Journal ArticleDOI
Emergence of Ceftazidime-Avibactam Resistance Due to Plasmid-Borne blaKPC-3 Mutations during Treatment of Carbapenem-Resistant Klebsiella pneumoniae Infections.
Ryan K. Shields,Liang Chen,Shaoji Cheng,Kalyan D. Chavda,Ellen G. Press,Avin C. Snyder,Ruchi Pandey,Yohei Doi,Barry N. Kreiswirth,M. Hong Nguyen,Cornelius J. Clancy +10 more
TL;DR: The development of resistance-conferring blaKPC-3 mutations in K. pneumoniae within 10 to 19 days of ceftazidime-avibactam exposure is troubling, but clinical impact may be ameliorated if carbapenem susceptibility is restored in certain isolates.
Journal ArticleDOI
Clinical Outcomes, Drug Toxicity, and Emergence of Ceftazidime-Avibactam Resistance Among Patients Treated for Carbapenem-Resistant Enterobacteriaceae Infections.
Ryan K. Shields,Brian A. Potoski,Ghady Haidar,Binghua Hao,Yohei Doi,Liang Chen,Ellen G. Press,Barry N. Kreiswirth,Cornelius J. Clancy,M. Hong Nguyen +9 more
TL;DR: Thirty-seven carbapenem-resistant Enterobacteriaceae-infected patients treated with ceftazidime-avibactam showed clinical success and survival rates and resistance was detected in 30% (3/10) of microbiologic failures.
Journal ArticleDOI
Ceftazidime-Avibactam Is Superior to Other Treatment Regimens against Carbapenem-Resistant Klebsiella pneumoniae Bacteremia.
Ryan K. Shields,M. Hong Nguyen,Liang Chen,Ellen G. Press,Brian A. Potoski,Rachel V Marini,Yohei Doi,Barry N. Kreiswirth,Cornelius J. Clancy +8 more
TL;DR: There are no data comparing outcomes of patients treated with ceftazidime-avibactam versus comparators for carbapenem-resistant Enterobacteriaceae infections and across treatment groups, there were no differences in underlying diseases, severity of illness, source of bacteremia, or strain characteristics.
Journal ArticleDOI
Colistin-Resistant Acinetobacter baumannii: Beyond Carbapenem Resistance
Zubair A. Qureshi,Lauren E. Hittle,Jessica A. O'Hara,Jesabel I. Rivera,Alveena Syed,Ryan K. Shields,Anthony W. Pasculle,Robert K. Ernst,Yohei Doi +8 more
TL;DR: Colistin-resistant A. baumannii occurred almost exclusively among patients who had received CMS for treatment of carbapenem-resistant, colist in-susceptible, and -resistant isolates, suggesting evolution of resistance during CMS therapy.
