This study investigates the impact of age and mean ICP on the shape and amplitude of ICP pulse waveform in traumatic brain injury (TBI). Additionally, it explores the association between morphological parameters and mortality after TBI. ICP recordings from 183 TBI patients (median age: 50 (30, 61) years) from the CENTER-TBI database were retrospectively analyzed. ICP morphology was assessed using the artificial intelligence-based pulse shape index (PSI) and peak-to-peak amplitude of ICP pulse waveform (AmpICP). The impact of mean ICP, age, and their interaction on PSI and AmpICP were estimated using factorial ANOVA. To account for influence of disturbance in the intracranial volume on AmpICP and PSI, a multiple regression analysis was performed using age, mean ICP, and the Rotterdam CT score as explanatory variables. The associations of AmpICP and PSI with six-month mortality were assessed using the area under the ROC curve (AUC). Age had a predominant influence on PSI (p < 0.01), accounting for 33.1% of its variance, while mean ICP explained 6.6% (p < 0.01). Conversely, mean ICP primarily affected AmpICP (p < 0.01), explaining 22.8% of its variance, with age contributing 8.0% (p < 0.01). A combined effect of age and mean ICP on AmpICP (p = 0.01) explained 11.7% of its variance but did not influence PSI. After accounting for Rotterdam CT score, the results remained consistent, indicating that advanced age has the strongest impact on PSI (β = 0.342, p < 0.01) while elevated mean ICP has dominant influence on AmpICP (β = 0.522, p < 0.01). Both AmpICP and PSI were moderately associated with mortality (AUC: 0.76 and 0.71, respectively). AmpICP and PSI capture distinct aspects of cerebrospinal compliance. PSI appears to reflect age-related stiffening of the cerebrovascular system, while AmpICP, influenced by mean ICP, indicates acute volume compensatory changes. Combined, they provide a more comprehensive assessment of cerebrospinal volume–pressure compensation. Both morphological metrics are associated with mortality after TBI. As cerebrospinal compliance declines with age, older TBI patients become more susceptible to uncontrolled rises in ICP, which can worsen their outcome.","PeriodicalId":10811,"journal":{"name":"Critical Care","volume":"180 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143434987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study represents a significant advancement in understanding acute kidney injury (AKI) in sepsis through urinary proteomics, offering promising insights to improve early recognition, predict responses to therapy, and implement or develop targeted treatment strategies. However, some aspects of the study warrant further discussion.</p><p>The observation that bacterial infections were more common in AKI-SP2, whereas COVID-19 predominated in AKI-SP1, supports the phenotype of endothelial dysfunction and inflammation. However, this raises the question of whether AKI-SP2 represents a distinct AKI sub-phenotype or reflects endothelial dysfunction typically associated with bacterial sepsis. Additionally, the observed overlap of proteins associated with AKI-SP2 and those linked to the risk of renal replacement therapy (RRT) raises the question of whether AKI-SP2 represents a distinct sub-phenotype or reflects a continuum of severe AKI. Clarification of this overlap could enhance our biological understanding of these processes. Moreover, the finding that urinary proteomic profiles of AKI-SP1 were largely similar to those of non-AKI patients suggests the need to refine diagnostic thresholds or explore alternative biomarker panels to improve classification accuracy. Addressing this issue may require the use of more specific biomarkers directly associated with the pathophysiological mechanisms of AKI to improve patient phenotyping. Given the study’s emphasis on urinary proteomics, defining sub-phenotypes directly from urinary proteomic data seems feasible, potentially yielding kidney-specific classifications that more accurately reflect local injury processes, which could enable tailored therapeutic strategies.</p><p>The timing of sample collection from patients with sepsis remains a significant challenge as the onset and progression of critical symptoms can vary widely between individuals. This variability is influenced by patient-related factors, type of pathogen involved, and specific organs affected. Given the dynamic progression of sepsis, aligning sample collection more precisely with the timing of sepsis onset could reduce variability and improve data consistency; however, this remains an extremely challenging, if not impossible, task. Alternatively, patients could be aligned based on the onset of AKI as defined by the KDIGO guidelines [2] or using predictive or functional AKI biomarkers such as Cystatin C rather than ICU admission, which may provide a more clinically relevant timeline for analysis, reduce inter-patient variability, and provide a clearer picture of AKI-related changes in urinary proteomic profiles as AKI evolves.

Over the years our perception and our understanding of the pathophysiology of HAI as evolved but the treatment remains basically limited to antimicrobial therapy [1]. In critically ill patients, there is evidence that the alteration of the interaction between the immune system and the microbiota could promotes the occurrence of HAI [1]. Accordingly, limiting microbiota injuries during the ICU stays could be a major mean to prevent HAI.</p><p>Nowadays, it is well established that all the epithelia are colonized by a diverse and dynamic living ecosystem composed of microorganisms, viruses and fungi. The microbiota, referring to the different communities of bacteria living symbiotically with our epithelia, participate to the proper development and functioning of our metabolic pathways (i.e. cognitive and immunity development) through a constant crosstalk between host and bacteria [2]. These microbiotas are constitutive of the human being [3,4,5]. We are not only a multicellular eukaryotes organism but a holobiont, an assemblage of different species of organisms, a <i>Homo microbicus.</i> [2, 6]</p><p>Healthy microbiota promotes host defense effectors, plays the role of a physical and functional barriers and inhibits the growth of pathogenic bacteria [7]. Conversely, altered microbiota (i.e. dysbiosis) plays an important role on the pathophysiology of immune and inflammatory disease: skin microbiotal dysbiosis is associated with the onset of atopic dermatitis, alteration of lung microbiota may be associated with asthma development and/or hospital-acquired pneumonia and gut microbiota dysbiosis plays a predominant role in Crohn’s disease [1, 8] Immunity and microbiota are interdependent, thus the alteration of one could lead to the alteration of the other [9].</p><p>Critically ill patients are exposed to conditions that impaired one or more physiologic functions commonly referred as acute injury (i.e. acute lung injury, acute kidneys injury). These injuries could result of either the direct hit of the organ or the consequences of an acute systemic response leading to potential complications and worsened outcomes.</p><p>As for other organs, the function of microbiota could be impaired in case of acute injury and strained its resilience. In critically ills patients, several factors, some intrinsic, some related to the underlying disease or iatrogenic, may promote dysbiosis (decrease in bacterial diversity, loss of commensal bacteria and increase of pathogenic bacterial inoculum) [1]. Accordingly, the alteration of lung microbiota is associated with the development of hospital-acquired pneumonia and acute respiratory syndrome [1]. Likewise, gut microbiota dysbiosis promotes colitis and play a role in acute kidneys injury [10].</p><p>These considerations lead us to propose the term of acut","PeriodicalId":10811,"journal":{"name":"Critical Care","volume":"15 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143401652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While several mortality risk factors have been described, a comprehensive synthesis is lacking. We conducted a meta-analysis of studies investigating mortality risk factors in Pertussis infections and validated those factors in a large cohort. Observational studies published in English were systematically searched in PubMed, EMBASE, and LiSSa databases from 01/2000 to 06/2024. The search yielded 816 unique citations. The primary outcome was mortality before discharge from the Pediatric Intensive Care Unit (PICU). Two independent reviewers assessed the risk of bias and extracted data. A REML-random effect model was used to calculate pooled prevalence and conduct the analysis. The identified risk factors were subsequently evaluated in a monocentric cohort of patients admitted to a tertiary hospital’s PICU for severe pertussis between January 1996 and December 2020. Data analysis was conducted between June and August 2024. Seventeen studies, including 2,725 patients, met the inclusion criteria. The pooled prevalence of mechanical ventilation, continuous renal replacement therapy, and Extracorporeal Membrane Oxygenation support were 55% (95% CI: 40–70; I2 = 98), 15% (95% CI: 3–27; I2 = 95), and 8% (95% CI: 3–12; I2 = 93), respectively.

In our retrospective cohort study of patients with sepsis and haematological malignancies, we fitted a single mixed effects multivariable logistic regression model to identify risk factors for mortality. In this model we included an interaction term between leukopenia and haematological malignancy (leukopenia x HM status), each coded as a binary variable, with leukopenia defined as total white cell count < 1.0 × 10<sup>9</sup> cells/L. In our model output we report the marginal effect of neutropenia in the presence or absence of haematological malignancy. This choice was made for interpretability and clinical relevance. For clinicians, the impact of neutropenia on mortality risk for septic patients with haematological malignancy is important to guide prognostication, escalation of treatment, and recognition of non-neutropenic patients in local guidelines for management of sepsis.</p><p>As noted by Caibao and colleagues, we further observed that leukopenia was associated with mortality in a univariable model, both in the presence and absence of haematological malignancy, but not in a multivariable model. Formal assessment of collinearity was performed using variance inflation factor (VIF) and all included variables had VIF < 10. This indicates that while crude mortality was higher in the neutropenic group, after adjustment for confounders including age, illness severity and year of admission, this was non-significant. Our findings are in keeping with previous studies reporting that neutropenia alone is not necessarily predictive of mortality after confounders including illness severity are accounted for [3, 4].</p><p>The complex relationship between leukopenia and mortality in septic patients with haematological malignancies warrants further study.
