Does the use of new cephalosporins follow the authorised, financed and approved indications? A study of their use in routine clinical practice in a tertiary hospital.

OBJECTIVES: To evaluate the appropriateness of ceftazidime-avibactam (C-A), ceftolozane-tazobactam (C-T) and ceftaroline prescriptions according to European Medicines Agency (EMA)/Spanish Agency of Medicines and Medical Devices (AEMPS) approved indications, financed indications in the Spanish health system and hospital Infection Commission (IC) recommendations in a tertiary hospital. METHODS: Observational, descriptive and retrospective study of inpatients aged ≥18 years, who were prescribed the above-mentioned antimicrobials during the period January-December 2020. Variables obtained were demographic (sex and age), pharmacological (antibiotic, use - empiric or targeted, indication) and microbiological (sensitivity testing and antibiotic tested) data. RESULTS: A total of 79 patients were included. C-A (n=40): 67.5% of patients were male, with a mean age of 61 (range 22-87) years. Empiric treatment was applied in 30% of the cases (n=12). De-escalation in 33.33% of individuals. Sensitivity testing was done in 92.86% of patients, including C-A in 57.69% of them. C-T (n=19): 89.47% of patients were male, with a mean age of 65 (range 18-82) years. An empiric approach was followed in 5.26% of subjects; de-escalation was performed in all cases due to culture with multidrug-resistant (MDR) Pseudomonas aeruginosa. Sensitivity testing was carried out in 100% of patients, including C-T in 26.32% of them. Ceftaroline (n=20): 70% of patients were male, with a mean age of 55.5 (range 23-79) years. Empiric treatment was applied to 30% of cases. In 50% of these subjects de-escalation was done. Sensitivity testing was done in 92.85% of them, but in none with ceftaroline. Regarding the percentage of appropriateness: approved EMA/AEMPS indications: C-A: 100%; C-T: 84.21%; ceftaroline: 75%; financed indications in the Spanish health system: C-A: 85%; C-T: 100%; ceftaroline: 15%; IC: C-A: 60%; C-T: 57.9%; ceftaroline: 15%. CONCLUSIONS: Our results highlight the importance of stewardship programmes in the decision-making process and in the follow-up of patients with infections caused by MDR microorganisms.

Clot Stiffness Measured By Seer Sonorheometry As a Marker Of Poor Prognosis In Hospitalized COVID-19 Patients.

A high risk of thrombotic complications has been observed among severely ill COVID-19 patients. Viscoelastic tests (VET) have shown a hypercoagulable profile in these patients, although so far there is no clear evidence on the use of these tools as predictors of risk in the clinical course of patients. In this study we aimed to evaluate the association between Quantra® sonorheometry VET parameters, standard coagulation tests and inflammatory markers in 69 patients with COVID-19 on hospital admission with disease severity and outcome. Inflammatory markers were elevated in a high percentage of patients, as were coagulation-related parameters such as fibrinogen and D-dimer levels. Quantra® sonorheometry analysis revealed increased clot stiffness (CS), especially due to increased fibrinogen contribution (FCS) in 63.7%. Analysis of clot stability to lysis (CSL) on the Quantra showed a value of 100%, suggesting hypofibrinolysis, in 32.4%. Age > 65 years, elevated values of fibrinogen, D-dimer, LDH, increased CS and CSL were significantly associated with worsening disease. The combination of elevated FCS and D-dimer values showed a particularly high prognostic value in distinguishing patients with severe symptomatology. In conclusion, FCS measured by Quantra® system and its combination with D-dimer could be established as a powerful tool to identify poor prognosis in COVID-19 patients on hospital admission.

The effects of an intervention to improve mental health during the COVID-19 quarantine: comparison with a COVID control group, and a pre-COVID intervention group.

ObjectiveThe COVID-19 pandemic has constituted an unprecedented challenge to society and science and it has provided an unexpected opportunity to explore the effects of a positive intervention in times of adversity and confinement. The goal was to evaluate the effects of a theory driven group intervention to cultivate mental health and flourishing. Design: A pre post design with three groups (151 individuals) was conducted, including an experimental group that received the intervention during the pandemic, a pre-COVID intervention group, and a COVID control group. Main Outcome Measures: Based on Keyes' concept of positive mental health, measures of subjective, psychological and social well-being were obtained, as well as an indicator of psychological distress (GHQ12). Results: Intervention groups showed an increase in well-being and the COVID control group a decrease. Change scores revealed significant differences. Overall percentage of individuals at risk of ill health in baseline was 25.2%, but after the intervention, the COVID control group reached 64.1%. Conclusions: Despite the limitations, the present findings suggest that interventions to sustain and improve mental health in times of crisis and adversity can be an effective approach.

IL-6 and Other Biomarkers associated with Poor Prognosis in a Cohort of Hospitalized Patients with COVID-19 in Madrid.

OBJECTIVES: There are several published works on the prognostic value of biomarkers in relation to the severity or fatal outcome of coronavirus disease 2019 (COVID-19). In Spain, the second European country in incidence of the disease at the time of data collection, there are few studies that include both laboratory parameters and clinical parameters. Our aim is to study the relationship of a wide series of biomarkers with admission to intensive care and death in a hospital in the Autonomous Community of Madrid (Spain), with special attention to IL-6 due to its role in the systemic inflammatory response associated with a worse prognosis of the disease. METHODS: Data were collected from 546 hospitalized patients with COVID-19. All of them had IL-6 results, in addition to other biochemical and haematological parameters. The difference of the medians for the selected parameters between the groups (ICU vs non-ICU, dead vs survivors) was studied using a Mann-Whitney analysis. The independent variables that predicted death were studied using a Cox proportional hazard regression model. RESULTS: Higher age and blood concentrations of ALT, creatinine, CK, cTnI, LDH, NT-proBNP, CRP, IL-6, leucocyte count and D-dimer together with lower blood concentrations of albumin and lymphocyte count were associated with mortality in univariate analysis. Age, LDH, IL-6 and lymphocyte count remained associated with death in multivariate analysis. CONCLUSIONS: Age, LDH, IL-6 and lymphocyte count, as independent predictors of death, could be used to establish more aggressive therapies in COVID-19 patients.
