Frail (PF) had...
After BNT162b2 messenger RNA vaccination, antibody levels to spike, receptor-binding domain, and virus neutralization were examined in 149 nursing home residents 110 healthcare worker controls. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-naive residents' median post-second vaccine dose titers are one-quarter that of SARS-CoV-2-naive workers.
Nursing home (NH) residents have borne a disproportionate share of SARS-CoV-2 morbidity and mortality. Vaccines limited hospitalisation death from earlier variants in this vulnerable population. With the rise Omicron future variants, it is vital to sustain broaden vaccine-induced protection. We examined effect boosting with BNT162b2 mRNA vaccine on humoral immunity Omicron-specific neutralising activity among NH healthcare workers (HCWs). longitudinally enrolled 85 (median age 77) 48 HCWs...
Introduction of monovalent COVID-19 mRNA vaccines in late 2020 helped to mitigate disproportionate COVID-19-related morbidity and mortality U.S. nursing homes (1); however, reduced effectiveness during the period Omicron variant predominance led recommendations for booster doses with bivalent that include an BA.4/BA.5 spike protein component broaden immune response improve vaccine against circulating variants (2). Recent studies suggest provide substantial additional protection SARS-CoV-2...
Healthcare personnel often use incorrect technique for donning and doffing of personal protective equipment (PPE).We tested the hypothesis that medical students receive insufficient training on correct methods PPE.We conducted a cross-sectional survey clinical rotations at two teaching hospitals to determine type they received in PPE technique. The performed simulations contaminated removal with fluorescent lotion gloves were assessed skin and/or clothing contamination. To obtain additional...
Burkholderia multivorans is a significant health threat to persons with cystic fibrosis (CF). Infections are difficult treat as this pathogen inherently resistant multiple antibiotics. Susceptibility testing of isolates obtained from CF respiratory cultures revealed that single agents selected different antibiotic classes were unable inhibit growth. However, all found be susceptible ceftazidime when combined the novel non-β-lactam β-lactamase inhibitor, avibactam (all minimum inhibitor...
Abstract Previously, by targeting penicillin-binding protein 3, Pseudomonas-derived cephalosporinase (PDC), and MurA with ceftazidime-avibactam-fosfomycin, antimicrobial susceptibility was restored among multidrug-resistant (MDR) Pseudomonas aeruginosa. Herein, ceftazidime-avibactam-fosfomycin combination therapy against MDR P. aeruginosa clinical isolate CL232 further evaluated. Checkerboard analysis revealed synergy between ceftazidime-avibactam fosfomycin. Accordingly, the resistance...
Bivalent SARS-CoV-2 vaccines were developed to counter increasing susceptibility emerging variants. We evaluated the durability of immunity and protection following first bivalent vaccination among nursing home residents. anti-spike neutralization titers from blood in 653 community residents before after each monovalent booster, a vaccine. Concurrent clinical outcomes using electronic health record data separate cohort 3783 Veterans Affairs (VA) homes who had received at least primary series...
We analyzed carbapenem-resistant Enterobacteriaceae (CRE) trends among patients from the US Veterans Health Administration (VHA). After emergence of CRE in eastern United States, resistance rates remained stable Klebsiella pneumoniae but increased Enterobacter cloacae complex, suggesting a "second epidemic". VHA offers vantage point for monitoring nationwide trends.
