ABSTRACT
BACKGROUND: We evaluated pre- and postimplementation of Virtuo on outcome in patients with gram-negative bacteremia using a quasiexperimental time-in-motion design. METHODS: Becton Dickinson BACTEC™ 9000 series (Bactec) (2018) and Virtuo system (2020) were utilized in a decentralized and centralized process, respectively. Data collected in August-December in 2018 and 2020 were analyzed with SPSS (ver 28). RESULTS: For 185 patients in each time period, patient age, gender, length of hospitalization were not different. However, blood culture (BC) volume was significantly lower in 2020 (7.1 ± 2.6 mL) compared to 2018 (8.9 ± 1.9 mL). Time from BC draw and time from pathogen identification (ID) to treatment change were both significantly faster in 2020 (52.9 ± 38.3 hours; 15.1 ± 27.4 hours), compared to 2018 (65.0 ± 46.3 hours; 23.8 ± 33.8), respectively. CONCLUSIONS: Replacement of decentralized Bactec with centralized Virtuo, resulted in significant improvement in management of patients gram-negative bacteremia.

INTRODUCTION: Coccidioidomycosis is most often an asymptomatic or mild self-limited respiratory infection, but in rare cases it can become disseminated and cause severe disease. CASE PRESENTATION: A 29-year-old man who was originally from Thailand and had been living in Arizona for 2 years presented with intermittent fevers, fatigue, and other nonspecific symptoms, including abdominal pain, nonbloody diarrhea, and pruritic rash. Initial laboratory values showed significant peripheral eosinophilia. Extensive evaluation revealed possible Strongyloides species infection. Shortly after, Coccidioidies species fungemia was found. Fevers and symptoms resolved after adequate treatment. DISCUSSION: Disseminated coccidioidomycosis with fungemia is very rare in immunocompetent individuals. Co-infection with Stronglyloides species is only reported in two other case reports. CONCLUSIONS: We report this case to raise awareness of a rare infection. In adequate epidemiological circumstances, co-infections Coccidioides and Strongyloides species should be considered in presence of fever and eosinophilia.

Endogenous bacterial endophthalmitis (EBE) is a rare but vision-threatening complication of bacteria spreading contiguously through the blood-ocular border. The condition is frequently associated with a poor visual prognosis and has even resulted in death. We present a case of a 48-year-old female with bilateral endogenous methicillin-resistant Staphylococcus aureus (MRSA)endophthalmitis further complicated by septic emboli, endocarditis, osteomyelitis, and septic polyarthralgia. Her vision did not return despite aggressive antibiotic therapy and urgent bilateral vitrectomy. This case presents an interesting and rare clinical vignette resulting in infection and damage of multiple organ systems that required aggressive management and carefully orchestrated multidisciplinary care.
