Synergistic effect of myocardial injury and mid-regional proAdrenomedullin elevation in determining clinical outcomes of SARS-CoV-2 patients.

Objective: Coronavirus disease 2019 (COVID-19) is a systemic disease induced by SARS-CoV-2 causing myocardial injury. To date, there are few data on the correlation between mid-regional proAdrenomedullin (MR-proADM) and myocardial injury. The aim of this study was to evaluate whether the association of myocardial injury and elevated mid-regional proAdrenomedullin values could predict mortality of SARS-CoV-2 patients, to offer the best management to COVID-19 patients. Materials and methods: All patients hospitalized for SARS-CoV-2 infection at the COVID-19 Center of the Campus Bio-Medico of Rome University were included between October 2020 and March 2021 and were retrospectively analyzed. Myocardial injury was defined as rising and/or fall of cardiac hs Troponin I values with at least one value above the 99th percentile of the upper reference limit (≥15.6 ng/L in women and ≥34.2 ng/L in men). The primary outcome was 30-day mortality. Secondary outcomes were the comparison of MR-proADM, CRP, ferritin, and PCT as diagnostic and prognostic biomarkers of myocardial injury. Additionally, we analyzed the development of ARDS, the need for ICU transfer, and length of stay (LOS). Results: A total of 161 patients were included in this study. Of these, 58 (36.0%) presented myocardial injury at admission. An MR-proADM value ≥ 1.19 nmol/L was defined as the optimal cut-off to identify patients with myocardial injury (sensitivity 81.0% and specificity 73.5%). A total of 121 patients (75.2%) developed ARDS, which was significantly more frequent among patients with myocardial injury (86.2 vs. 68.9%, p = 0.015). The overall 30-day mortality was 21%. Patients with myocardial injury presented significantly higher mortality compared to those without the same (46.6 vs. 6.8%, p < 0.001). When dividing the entire study population into four groups, based on the presence of myocardial injury and MR-proADM values, those patients with both myocardial injury and MR-proADM ≥ 1.19 nmol/L presented the highest mortality (53.2%, p < 0.001). The combination of myocardial injury and MR-proADM values ≥ 1.19 nmol/L was an independent predictor of death (OR = 7.82, 95% CI = 2.87-21.30; p < 0.001). Conclusion: The study is focused on the correlation between myocardial injury and MR-proADM. Myocardial injury induced by SARS-CoV-2 is strongly associated with high MR-proADM values and mortality.

Pediatric Antimicrobial Stewardship: State of the Art.

PURPOSE OF REVIEW: We aim to systematically review the literature on the effectiveness of pediatric antimicrobial stewardship programs (ASPs) and antimicrobial stewardship (AS) strategies in the United States (US) inpatient setting. Furthermore, we review current gaps and challenges for unique pediatric populations and those in ambulatory settings. RECENT FINDINGS: Misuse and overuse of antimicrobials have been identified as key factors for antimicrobial resistance (AR). Multiple professional organizations support the implementation of hospital-based ASPs to decrease antimicrobial consumption, improve patient outcomes, and reduce healthcare costs. There is limited data on the effectiveness of inpatient pediatric ASPs and AS strategies in unique populations. Furthermore, there is a paucity of evidence on ASPs in ambulatory settings. This review contributes to the growing body of evidence that supports the use of pediatric ASPs to optimize antimicrobial therapy in the inpatient setting as well as in unique patient populations and ambulatory settings. Active stewardship is critical and antimicrobial consumption is a key outcome metric for programs.

Performance of a Novel Antipseudomonal Antibiotic Consumption Metric Among Academic Medical Centers in the United States.

A metric was developed to identify hospital proportion of carbapenem consumption (PoCC) among antipseudomonal antibiotics. The PoCC varied significantly among academic medical centers by Census Bureau geographic division after adjusting for patient mix. This metric may be useful in identifying disproportionate carbapenem use and potential carbapenem overuse. Infect Control Hosp Epidemiol 2018;39:229-232.

Are gym surfaces reservoirs for Staphylococcus aureus? A point prevalence survey.

We sought to identify staphylococcal contamination of gymnasium surfaces. Various environmental surfaces were cultured at a university fitness center. Ten out of 99 samples yielded Staphylococcus aureus, all of which were methicillin-susceptible. Gym surfaces may be colonized with staphylococci and could play a role in community transmission of staphylococcal species.
