Introduction: The use of selective digestive decontamination (SDD) in critically ill patients remains controversial. The impact of antimicrobial resistance varies according to multiple factors attributed to the type of patient and the characteristics of intensive care units (ICU).
Aim of the study: to describe the effect of the implementation of a selective digestive decontamination protocol on the incidence of nosocomial infections and colonization of multidrug-resistant organisms (MDRO) in an intensive care unit.
Materials and methods: Prospective observational study in a general ICU of a University Hospital. All patients admitted for 2 years (divided into 1-year periods) before and after the implementation of the SDD were included. This intervention was performed in all patients who received invasive mechanical ventilation in the second period. Incidence density rates were determined for all nosocomial infections (per days of stay) and device-associated infections (per days of use), and risk ratio (RR) were calculated with 95% confidence intervals. Microbiological surveillance of the colonization status of patients was performed on admission and on a weekly basis. A univariate analysis was performed for comparison between groups. A p<0.05 was considered significant.
Results: A total of 1532 patients were included in the pre-intervention period (pre-SDD) and 1734 in the post-intervention period (post-SDD). The incidence of all infections decreased [9.21 vs 6.54 per days of stay; RR: 0,71 (0,428 – 1,172), p=0,16], although not significantly. Both catheter-related bacteremias and all catheter-related bacteremias together (primary and secondary) were significantly reduced [4.49 vs 0.71 per 1000 days of use; RR: 0,157 (0,017 – 0,723), p=0,006]. The colonization rates by MDRO also decreased (3.26% vs 2.36%), but not significantly.
Conclusions: Implementation of SDD significantly decreased the number of catheter-related bacteraemias, without an increase in MDRO colonization.

Introduction: End-stage heart failure due to dilated cardiomyopathy remains a major indication for advanced mechanical circulatory support and heart transplantation. Left ventricular assist devices have emerged as a vital bridge to transplant, improving survival and functional status. However, right ventricular failure following LVAD implantation is a significant and potentially fatal complication, requiring careful management to optimize outcomes.
Case presentation: We present the case of a 46-year-old male with post-myocarditis dilated cardiomyopathy, severely reduced left ventricular ejection fraction (21%), severe functional mitral and tricuspid regurgitation, and NYHA class IV heart failure. Despite optimal medical therapy, including inotropic support, the patient progressed to multiorgan dysfunction necessitating renal replacement therapy. A HeartMate 3 LVAD was implanted as a bridge to transplantation. The postoperative course was complicated by severe right ventricular failure, requiring prolonged inotropic support and careful hemodynamic management. Despite these challenges, the patient successfully underwent orthotopic heart transplantation. His postoperative evolution was favorable, with stable graft function and good clinical recovery documented during follow-up.
Conclusion: Right ventricular failure remains a major complication following LVAD implantation, significantly impacting outcomes. While LVADs have revolutionized the management of end-stage heart failure, heart transplantation continues to represent the definitive therapy offering superior long-term survival.

Aim of the study: The rupture of delayed formed splenic pseudoaneurysms after pediatric blunt splenic injuries undergoing nonoperative management (NOM) can be life-threatening. We aimed to identify the sub-phenotypes predicting delayed splenic pseudoaneurysm formation following pediatric blunt splenic injury using latent class analysis (LCA).
Material and Methods: In this retrospective observational study conducted using a multicenter cohort of pediatric trauma patients, we included pediatric patients (aged ≤16 years) who sustained blunt splenic injuries and underwent NOM from 2008 to 2019. LCA was performed using clinically important variables, and 2–5 sub-phenotypes were identified. The optimal number of sub-phenotypes was determined on the basis of clinical importance and Bayesian information criterion. The association between sub-phenotyping and delayed splenic pseudoaneurysm formation was analyzed using univariate logistic regression analysis with odds ratios (ORs) and 95% confidence intervals (CIs).
Results: The LCA included 434 patients and identified three optimal sub-phenotypes. Contrast extravasation (CE) of initial CT in the spleen was observed in 22 patients (68.8%) in Sub-phenotype 1, 49 patients (25.7%) in Sub-phenotype 2, and 22 patients (10.4%) in Sub-phenotype 3 (p = 0.007). Delayed splenic pseudoaneurysm was observed in 46 patients (10.6%), including seven patients (21.9%) in Sub-phenotype 1, 25 patients (13.1%) in Sub-phenotype 2, and 14 patients (6.6%) in Sub-phenotype 3 (p = 0.01). Logistic regression analysis for delayed splenic pseudoaneurysm formation using Sub-phenotype 3 as the reference revealed an OR (95% CI) of 3.94 (1.45–10.7) in Sub-phenotype 1 and 2.12 (1.07–4.21) in Sub-phenotype 2.
Conclusions: The LCA identified three sub-phenotypes showing statistically significant differences for delayed splenic pseudoaneurysm formation. Our findings suggest that cases with CE on initial CT imaging may be at increased risk of delayed splenic pseudoaneurysm formation.

At the heart of biomedical publishing integrity lies peer review—long regarded as the “gold standard” of scientific validation. Yet, despite its foundational role, peer review today reveals critical shortcomings: inconsistency, lack of transparency, slow turnaround, and susceptibility to bias. As the scientific landscape evolves with rising submission volumes, data complexity, and urgency for rapid knowledge dissemination, it is no longer enough to refine peer review; it must be reimagined.
As editors and long-time participants in academic publishing, we have consistently faced the challenges of writing, reviewing, and managing peer evaluations. Identifying qualified reviewers and synthesizing their feedback into fair editorial decisions remains a formidable task. This editorial outlines our concerns and envisions how artificial intelligence (AI) can enhance—not replace—peer review in medicine. Over 90% of the initial text was generated with ChatGPT Scholar using structured prompts; it has since been extensively revised by the authors. [More]

Introduction: There is limited information about trends in mortality of intensive care unit (ICU) patients with Coronavirus Disease-2019 (COVID-19) throughout the entire pandemic period.
Aim: We compared the ICU mortality among the four consecutive waves of the pandemic, according to the virus variant predominance.
Methods: This is a retrospective study of prospectively collected data extracted from our COVID-19 clinical database. All adult patients with confirmed SARS-CoV-2 infection, consecutively admitted to our ICU from March 2020 through April 2022, were included. For the analysis we used the dates of the four periods of the pandemic, according to the predominance of different SARS-CoV-2 variants in Greece. Kaplan-Meier and Cox proportional hazards analyses were used.
Results: In total, 805 patients [median (IQR) age 67 (56-76) years, 68% males] were included. APACHE II, Charlson, and SOFA scores were 14 (11-19), 3 (2-5) and 7 (4-9), respectively; 674 (84%) patients required invasive mechanical ventilation. ICU length of stay was 15 (8-29) days, and mechanical ventilation duration was 11 (4-24) days. ICU and hospital mortality was 48% and 54%, respectively. Kaplan-Meier survival curves revealed no significant differences in ICU mortality among the four waves. Age, malignancy, chronic pulmonary disease and SOFA score were independent predictors of ICU mortality, but the pandemic waves themselves were not. Age had a significant impact on ICU mortality across all waves.
Conclusion: The effect of COVID-19 wave (and consequently of the SARS- CoV-2 variant) on ICU mortality seems to be trivial, and therefore our focus should be shifted to other risk factors, such as age and comorbidities. These findings along with those of other studies could be useful for modelling the evolution of future outbreaks.

DOI: 10.2478/jccm-2025-0033

Objective: This study investigated whether incidental hyperglycemia serves as an independent risk factor for myocardial infarction (MI) among non-diabetic patients in the emergency department.
Methods: A retrospective case-control study analyzed data from one thousand non-diabetic patients aged 18-85 years who visited the emergency department during January through October two thousand twenty-four Patients were classified into two equal groups based on their random blood glucose levels: patients with glucose levels above 140 mg/dL formed the hyperglycemia group and patients with glucose levels below 140 mg/dL belonged to the normoglycemia group. The analysis employed logistic regression to assess how hyperglycemia related to MI while controlling for various demographic and clinical variables.
Results: The incidence of MI was found in 61.4% of patients with hyperglycemia but only in 25.8% of patients with normoglycemia. Multivariable analysis revealed that incidental hyperglycemia increased the odds of MI by 2.42 times. The risk was higher among male patients and further increased when glucose levels exceeded 180 mg/dL.
Conclusions: Non-diabetic emergency department patients who experience incidental hyperglycemia show a high risk of developing MI. The evaluation of cardiovascular risk should begin with emergency physicians, who should consider elevated random blood glucose as a potential marker for identifying patients likely to benefit from early assessment and follow-up.

Introduction: COVID-19 pneumonia manifests with a wide range of clinical symptoms, from minor flu-like signs to multi-organ failure. Chest computed tomography (CT) is the most effective imaging method for assessing the extent of the pulmonary lesions and correlates with disease severity. Increased workloads during the COVID-19 pandemic led to the development of various artificial intelligence tools to enable quicker diagnoses and quantitative evaluations of the lesions.
Aim of the study: This study aims to analyse the correlation between lung lesions identified on CT scans and the biological inflammatory markers assessed, to establish the survival rate among patients.
Methods: This retrospective study included 120 patients diagnosed with moderate to severe COVID-19 pneumonia who were admitted to the intensive care unit and the internal medicine department between September 2020 and October 2021. Each patient underwent a chest CT scan, which was subsequently analysed by two radiologists and an AI post-processing software. On the same day, blood was collected from the patients to determine inflammatory markers. The markers analysed in this study include the neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio, platelet-lymphocyte ratio, systemic immune-inflammatory index, systemic inflammation response index, systemic inflammation index, and serum interleukin-6 value.
Results: There were strong and very strong correlations between the derived inflammatory markers, interleukin-6, and the CT severity scores obtained by the AI algorithm (r=0.851, p<0.001 in the case of NLR). Higher values of the inflammatory markers and high lung opacity scores correlated with a decreased survival rate. Crazy paving was also associated with an increased risk of mortality (OR=2.89, p=0.006).
Conclusions: AI-based chest CT analysis plays a crucial role in assessing patients with COVID-19 pneumonia. When combined with inflammatory markers, it provides a reliable and objective method for evaluating COVID-19 pneumonia, enhancing the accuracy of diagnosis.

Acute respiratory distress syndrome (ARDS) is a severe inflammatory reaction in the lungs caused by sudden pulmonary and systemic injuries. Clinically, this diverse syndrome is marked by sudden hypoxemic respiratory failure and the presence of bilateral lung infiltrates visible on a chest X-ray. ARDS management remains largely supportive, with a focus on optimizing mechanical ventilation strategies and addressing the underlying causes of lung injury. The current pharmacological approach for ARDS primarily focuses on corticosteroids, neuromuscular blocking agents, and beta-2 agonists, however, none has been definitively proven to be consistently effective in improving clinical outcomes. This review summarizes the latest evidence regarding the effectiveness and limitations of these pharmacological interventions, identifying key areas where further research is needed.

Introduction: Hemoptysis is a commonly encountered diagnosis caused by blood originating from the respiratory tract. Current pharmacological guideline recommendations for treatment do not exist. Tranexamic acid is a synthetic anti-fibrinolytic used in the management of various bleeding complications. Tranexamic acid has gained popularity for the treatment of hemoptysis with limited side effect knowledge. Our aim is to describe the clinical characteristics of patients receiving nebulized tranexamic acid for hemoptysis and compare clinical outcomes to those of patients receiving supportive care.
Materials and Methods: This is a retrospective descriptive analysis performed in medical and ICU units at three tertiary hospitals. All patients were hospitalized with hemoptysis between January 1st, 2018 – December 31st, 2021. Demographic information, severity variables, and clinical outcomes were collected from medical records. For statistical analysis, we used t-test for continuous variables, chi-square or fishers’ exact test for categorical variables, and propensity analysis to adjust for disease severity and underlying medical conditions.
Results: 488 patients were identified; 96 received tranexamic acid. There were slightly more smokers in the no TXA group (p = 0.04) but otherwise the two groups were similar in terms of demographic characteristics. The average length of hospital and ICU stay, need for mechanical ventilation or bronchoscopy, and mortality were significantly higher in the tranexamic acid group (p<0.01). The propensity analysis showed higher odds of death with nebulized tranexamic acid use, OR 2.51 (1.56-4.02).
Conclusions: There appears to be an indication bias for tranexamic acid based on disease severity without an obvious improvement in clinical outcomes. Our analysis suggests that nebulized tranexamic acid for hemoptysis may be potentially harmful, and further larger prospective research is warranted.
