Outcomes of corticosteroid therapy in patients with viral community-acquired pneumonia.

AIM: The objective of this study was to assess the therapeutic effects of corticosteroids in adult patients hospitalized with viral community-acquired pneumonia. METHODS: This is a retrospective analysis of data collected prospectively from November 1996 to June 2024. All adult patients with viral community-acquired pneumonia were enrolled. The primary outcome was 30-day mortality. Secondary outcomes included all-cause in-hospital mortality, ICU admission, length of ICU and hospital stay, mechanical ventilation, and 1-year mortality. Propensity score matching (PSM) was used to obtain balance among the baseline variables in the two groups. RESULTS: Of the 524 patients with viral pneumonia, 30 (6%) received corticosteroids and 494 (94%) did not. Patients were primarily male (n = 299, 57%), with a median [Q1-Q3] age of 66.9 [55-81] years. The 3:1 propensity matching procedure identified 90 patients not treated with corticosteroid (CS-) as controls. After PSM, no difference in 30-day mortality was found [7% (95%CI 1 to 22%) vs. 4% (95%CI 1 to 11%), p = 0.639]. The risk of death at 30 days did not differ significantly in unmatched and matched cohorts [Hazard Ratio (HR) 1.33 (0.32-5.63), p = 0.695 vs. HR 1.51 (0.28-8.27), p = 0.632, respectively]. Nor were differences found in hospital length of stay, ICU admission and length of stay, or mechanical ventilation requirement and duration between matched and unmatched CS + and CS-. CONCLUSIONS: There were no significant differences in the primary and secondary outcomes regarding the use of corticosteroids in patients with viral pneumonia.

Generalized music therapy to reduce neuroactive drug needs in critically ill patients. Study protocol for a randomized trial.

BACKGROUND: Critically ill patients are exposed to several physical and emotional stressors, needing analgesic and sedative drugs to tolerate invasive procedures and the harsh intensive care unit (ICU) environment. However, this pharmacological therapy presents several side effects: guidelines suggest using a light sedation target, keeping critically ill patients calm, conscious, and cooperative. Personalized music therapy (MT) can reduce stress and anxiety, decreasing the need for drugs. The aim of the current investigation is to compare different approaches for MT in the ICU: a personalized approach, with music selected by patients/families and listened through headphones, or a generalized approach, with ambient music chosen by a music therapist and transmitted through speakers. PRIMARY OUTCOME: number of days "free from neuroactive drugs" in the first 28 days after ICU admission. SECONDARY OUTCOMES: total amount of neuroactive drugs (midazolam, propofol, morphine, fentanyl, haloperidol), stress during ICU stay (sleep at night, anxiety and agitation, use of physical restraints, stressors evaluated at discharge), the feasibility of generalized MT (interruptions requested by staff members and patients/families). METHODS: Randomized, controlled trial with three groups of critically ill adults: a control group, without MT; a personalized MT group, with music for at least 2 h per day; a generalized MT group, with music for 12.5 h/day, subdivided into fifteen 50-min periods. DISCUSSION: One hundred fifty-three patients are expected to be enrolled. This publication presents the rationale and the study methods, particularly the strategies used to build the generalized MT playlist. From a preliminary analysis, generalized MT seems feasible in the ICU and is positively received by staff members, critically ill patients, and families.

New Guidelines for Severe Community-acquired Pneumonia.

In 2023, the new European guidelines on severe community-acquired pneumonia, providing clinical practice recommendations for the management of this life-threatening infection, characterized by a high burden of mortality, morbidity, and costs for the society. This review article aims to summarize the principal evidence related to eight different questions covered in the guidelines, by also highlighting the future perspectives for research activity.

Retrospective analysis of bacteraemia due to extended-spectrum beta-lactamase-producing Enterobacterales: the challenge of healthcare-associated infections.

Objectives: Healthcare-associated bacteraemia is defined as bacteraemia diagnosed ≤48 h after hospital admission in patients recently exposed to healthcare procedures or settings. It differs from hospital-acquired bacteraemia, which is diagnosed >48 h after hospital admission. Healthcare-associated bacteraemia is reported increasingly, often due to resistant pathogens including extended-spectrum beta-lactamase (ESBL) producers, representing a challenge to empirical treatment. This study aimed to assess the appropriateness of empirical treatment for ESBL bacteraemia at the authors' centre, to perform a descriptive analysis according to the mode of infection acquisition (community-acquired, healthcare-associated, hospital-acquired), and to assess the risk factors for mortality. Methods: A retrospective study on patients with ESBL bacteraemia was undertaken. Results: In total, 129 consecutive cases of bacteraemia due to ESBL producers were included in this study. Compared with community- and hospital-acquired bacteraemia, healthcare-associated bacteraemia affected older patients (P=0.001) and patients with higher Charlson Comorbidity Index scores (P=0.007), and was more frequently associated with piperacillin-tazobactam resistance (P=0.025) and multi-drug resistance (P=0.026). Overall, ineffective empirical treatment was common (42%). Factors associated with 30-day mortality were septic shock [odds ratio (OR) 7.096, 95% confidence interval (CI) 2.58-24.58], high Pitt score (OR 6.636, 95% CI 1.71-23.62) and unknown source of bacteraemia (OR 19.28, 95% CI 2.80-30.70). Conclusions: Antimicrobial stewardship interventions focusing on both in-hospital and community settings are advocated to better manage healthcare-associated infections due to ESBL producers.

Elevated Troponin in Patients With Coronavirus Disease 2019: Possible Mechanisms.

Coronavirus disease 2019 (COVID-19) is a pandemic that has affected more than 1.8 million people worldwide, overwhelmed health care systems owing to the high proportion of critical presentations, and resulted in more than 100,000 deaths. Since the first data analyses in China, elevated cardiac troponin has been noted in a substantial proportion of patients, implicating myocardial injury as a possible pathogenic mechanism contributing to severe illness and mortality. Accordingly, high troponin levels are associated with increased mortality in patients with COVID-19. This brief review explores the available evidence regarding the association between COVID-19 and myocardial injury.
