Overall, NRS reduces the work of breathing and relieves dyspnea in many patients with ARF, sometimes avoiding the need for intubation and invasive mechanical ventilation with variable efficacy across diverse clinical scenarios. Nonetheless, prolonged exposure to NRS in the presence of sustained high respiratory drive and effort can result in respiratory muscle fatigue, cardiovascular collapse, and impaired oxygen delivery to vital organs, leading to poor outcomes in patients who ultimately fail NRS and require intubation. Assessment of patients’ baseline characteristics before starting NRS, close physiological monitoring to evaluate patients’ response to respiratory support, adjustment of device settings and interface, and, most importantly, early identification of failure or of paramount importance to avoid the negative consequences of delayed intubation. This review highlights the role of respiratory monitoring across various modalities of NRS in patients with ARF including dyspnea, general respiratory parameters, measures of drive and effort, and lung imaging. It includes technical specificities related to the target population and emphasizes the importance of clinicians’ physiological understanding and tailoring clinical decisions to individual patients’ needs.","PeriodicalId":10811,"journal":{"name":"Critical Care","volume":"27 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143805774","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}

Current epidemiological data of LA patients requiring intensive care unit (ICU) admission are limited. This multicentre retrospective study included adults admitted to 24 ICUs in France between January 2010 and December 2020. Risk factors for mortality were identified by multivariate analysis. A propensity score was used to adjust for confounders related to the presence of portal vein thrombosis. 335 patients were enrolled. The median age was 66 years [53–73] and 68% were male. Commons comorbidities included diabetes (29.9%) and cancer or haematological disease. Septic shock was the main reason for admission (58%). The median SAPS2 score at ICU admission was 42 [31–53] and the SOFA score was 6 [3–9]. The putative origin of LA was biliary (31%), while 40% were cryptogenic. Most patients (60%) had a solitary LA, involving the right lobe (38.8%), with a median diameter of 67 mm [47–91]. Associated portal vein thrombosis (PVT) was present in 13.4% of cases. Microbiological documentation was obtained in 82% of patients, showing gram-negative bacilli (59.7%), mainly Escherichia coli (19.6%) and Klebsiella spp. (19.1%), and gram-positive cocci (29.6%), mainly Streptococcus spp. (17.1%). Drainage was performed in 62% of cases, 40% within 48 h. The median duration of antibiotic therapy was 35 days [21–42]. During hospitalisation, 62% of patients required vasopressors and 29% required mechanical ventilation. In-ICU mortality was 11.6%. Multivariate analysis showed that organ dysfunction illustrated by SOFA score (HR 3.45 [1.95–6.09], p < 0.001) and PVT (HR 3.14 [1.54–6.39], p = 0.001) were significant risk factors for mortality. Drainage was not associated with improved short-term survival (HR 1.22 [0.65–2.72], p = 0.52).

Early detection is crucial, as delays in treatment substantially increase the risk of fatal outcomes with each passing hour. However, no specific molecular marker or definitive blood test for sepsis detection exists.&lt;/p&gt;&lt;p&gt;Early warning scores (EWS), such as the National Early Warning Score (NEWS), are widely used in hospitals to identify clinical deterioration. In general hospital wards, sepsis detection relies primarily on intermittent vital sign measurements, including heart rate (HR), blood pressure (BP), and body temperature, with less frequent monitoring of oxygen saturation (SpO&lt;sub&gt;2&lt;/sub&gt;) and respiratory rate (RR). However, these measurements are typically taken only a few times daily, creating a gap where early signs of deterioration may go unnoticed—especially at night or in outpatient settings.&lt;/p&gt;&lt;p&gt;A recent study demonstrated that an electronic alert system integrating qSOFA components, refreshing electronic medical records (EMRs) every four hours, significantly reduced 90-day in-hospital mortality [1]. This underscores the potential of continuous sepsis screening via biosensors as a valuable strategy for improving patient safety and reducing sepsis-related mortality.&lt;/p&gt;&lt;h3&gt;The emergence of wearable biosensors for sepsis detection&lt;/h3&gt;&lt;p&gt;Advancements in wearable and wireless sensors now allow real-time, continuous monitoring of vital signs. These cost-effective solutions enhance patient observation and facilitate early intervention by triggering alarms when physiological parameters indicate potential deterioration. However, ensuring high data quality, system interoperability, and intelligent alerting remains challenging.&lt;/p&gt;&lt;p&gt;Several wearable biosensors have shown promising results. Most available devices are still limited in how many parameters they can measure accurately. Additionally, many devices require adhesive electrodes on the chest or additional sensors for measuring temperature in the armpit or SpO&lt;sub&gt;2&lt;/sub&gt; at the fingertip. These features often reduce patient comfort and adherence to continuous monitoring.&lt;/p&gt;&lt;p&gt;Biosensors must be minimally invasive and comfortable to wear for extended periods for optimal patient acceptance. Current wrist-worn biosensors offer a promising solution by providing high-quality data on vital parameters necessary for calculating the NEWS2 score, which the British NHS endorses as an improvement over the original NEWS.

We aimed to discuss mentalisation, a process already known to psychotherapists but less so to critical care clinicians [3]. The main point of our commentary was to explore the possible role of mentalisation in the highly emotive environment of ICU, as a tool in conflict prevention and resolution. You are very right to point out that the actual impact of the process on outcomes is far from evidenced-based; however, being curious about one’s own reactions and endeavouring to understand the reactions of others is an attitude with strong face validity and hence conceptually attractive. Yet, robust scientific evaluation is needed to ensure that the anticipated benefits materialise and are not offset by unanticipated consequences.&lt;/p&gt;&lt;p&gt;We completely agree with your second comment on the importance of culturally competent communication in ICU. Indeed, in an increasingly diverse world, ICU patient and family communication must incorporate skills that accommodate the language, ethnicity and religious differences that exist. Logically, the capacity to understand other people’s intentional or inner mental states while acknowledging one’s own (mentalisation) would improve with increased cross-cultural awareness. Despite the implicit link, this positive association between cultural competence and improved patient/ family outcomes is also lacking [4]. It is obvious that the impact of such educational interventions (cultural competence, mentalisation techniques) requires better quality studies in order to provide robust conclusions about their effectiveness.&lt;/p&gt;&lt;p&gt;No datasets were generated or analysed during the current study.&lt;/p&gt;&lt;ol data-track-component=\"outbound reference\" data-track-context=\"references section\"&gt;&lt;li data-counter=\"1.\"&gt;&lt;p&gt;Vahedian-Azimi A.

[1] regarding our study [2] on “Time to positivity (TTP) as a predictor of catheter-related bacteremia and mortality in &lt;i&gt;Pseudomonas aeruginosa&lt;/i&gt; bloodstream infections (PAE-BSI)”. Their insights highlight important aspects that warrant further discussion, particularly regarding additional variables that could influence the TTP, and about long-term outcome.&lt;/p&gt;&lt;p&gt;In response to the first point, we acknowledge the potential influence of resistance on TTP. We found that susceptible &lt;i&gt;P. aeruginosa&lt;/i&gt; strains had a significantly shorter TTP (Table 1). Moreover, this property was consistent across all antibiotic families. Since no clinically relevant TTP cut-off for predicting resistance was identified, this data was not included in the main article due to length limitation. This finding supports that resistant strains may decelerate their replication rates because resistance mechanisms affect one or more metabolic pathways involved in bacterial replication. A previous study in &lt;i&gt;Staphylococcus aureus&lt;/i&gt; bacteremia also demonstrated shorter TTP for methicillin-susceptible strains compared to methicillin-resistant ones [3]. However, we have to recognize that other studies focused in Enterobacterales and other non-fermenting gram-negative bacilli have shown contradictory results [4, 5].&lt;/p&gt;&lt;figure&gt;&lt;figcaption&gt;&lt;b data-test=\"table-caption\"&gt;Table 1 Factors associated with shorter TTP.

Although the role of host immunity seems reasonable, our data (Table 1) did not support this statement. In the univariable analysis, chronic kidney disease (CKD) in hemodialysis, neutropenia and corticosteroid therapy were significantly associated with shorter TTP. However, no one was finally included in the multivariable analysis. In the case of CKD in hemodialysis the reason to be excluded is that the majority of these cases were catheter-related bacteremia that is a significant determinant of shorter TTP. Neutropenia reduces the host capacity to clear bacteria from infected tissue resulting in higher bacterial loads in the bloodstream and corticosteroid therapy impair the reticuloendothelial system located at the liver and the spleen, both responsible of rapid bacterial clearance from the blood [6, 7]. Therefore, weak immune system increases the inoculum at the infectious foci and that is the variable superior in the multivariable analysis. According to our findings, we have summarized the main determinants of TTP in Fig. 1.&lt;/p&gt;&lt;figure&gt;&lt;figcaption&gt;&lt;b data-test=\"figure-caption-text\"&gt;Fig. 1&lt;/b&gt;&lt;/figcaption&gt;&lt;pictu","PeriodicalId":10811,"journal":{"name":"Critical Care","volume":"39 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744826","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 incidence of weaning-induced pulmonary oedema (WIPO) is poorly documented and shows huge variations. Our study aims to investigate the incidence and risk factors for WIPO during weaning from mechanical ventilation in general critically ill patients. This multicentre study was conducted in France, Italy, and India. Adult critically ill patients receiving invasive ventilation were included once a spontaneous breathing trial (SBT) was performed. The SBT technique could be either T-piece or pressure support mode with (PSV-PEEP) or without positive end expiratory pressure (PEEP) (PSV-ZEEP). A consensual diagnosis of WIPO was made a posteriori by five experts who analysed changes observed during the SBT that were retrospectively recorded. From July 2019 to February 2021, 634 SBTs were performed in 500 patients from 13 ICUs. Weaning success occurred in 417 patients (66%) and weaning failure in 217 (34%). Weaning was short in 414 (83%) of SBTs, difficult in 47 (9%) SBTs, and prolonged in 39 (8%) SBTs. WIPO was diagnosed in 79 (12%) cases, which accounted for 36% of the 217 weaning failures. WIPO occurred in 54/358 (15%) of T-piece SBT, in 7/84 (8%) of PSV-PEEP SBT (p = 0.072 vs. T-piece), and in 18/192 (9%) of PSV-ZEEP SBT (p = 0.002 vs. T-piece). In multilevel logistic regression analysis including 202 weaning failures from 149 different patients, COPD, and previous cardiomyopathy were identified as independent risk factors associated with WIPO. In general ICU patients, WIPO accounts for 36% of weaning failure cases. Previous heart disease and COPD are two independent risk factors for developing WIPO during the weaning process.

At least one third of the survivors develop psychological disorder, including anxiety, depression or post-traumatic stress disorder [1]. There is also evidence that the relatives can suffer from emotional distress during and after the ICU stay of their loved one, leading to the so-called post-intensive care syndrome-family [2]. The burden is also considerable for relatives of patients who die in ICU, leading potentially to a complicated bereavement.&lt;/p&gt;&lt;p&gt;Patient- and family-cantered care in ICU is a holistic model of health care recognizing the importance of a humanized environment to improve recovery, in which psychologists may play a key role [3]. In 2021, the French government asked the scientific societies to draw up an overview of the presence of psychologists in ICUs. A national decree was also published in April 26th, 2022, recommanding the presence of psychologists in French ICUs (https://www.legifrance.gouv.fr/eli/decret/2022/4/26/SSAH2206984D/jo/texte). However, how this decree is translated into practice is unknown. (https://igas.gouv.fr/L-offre-de-soins-critiques-reponse-au-besoin-courant-et-aux-situations). In this context, the aim of the present study was to describe the presence of psychologists in French ICUs and to identify the potential obstacles to their effective integration in ICU teams.&lt;/p&gt;&lt;p&gt;A questionnaire was designed by the Patients and Relatives Working Group of the French Society of Intensive Care Medicine (SRLF). The first question was &lt;i&gt;“Does your ICU team include a dedicated psychologist caring for patients and relatives?”&lt;/i&gt;. In case of positive answer, the next question was &lt;i&gt;“What proportion of his working time is dedicated to ICU?”&lt;/i&gt;. In case of negative answer, two further questions were asked: “&lt;i&gt;Do you have access to psychologists from other departments in your hospital?”&lt;/i&gt; and &lt;i&gt;“What are the main barriers preventing the inclusion of a psychologist in your ICU team?”.&lt;/i&gt; The following barriers were explored: 1) no financial resources, 2) hospital management decision, 3) no interest.\u0000&lt;/p&gt;&lt;p&gt;The survey was conducted between January and December 2023. A total of 322 ICUs were identified, representing approximately 90% of all the ICUs in the country. The medical director and/or the head nurse of each ICU were contacted by telephone or email. Twenty ICUs did not respond (response rate: 302/322, 97%). The characteristics of the participating ICUs are described in Table 1.

This study aims to further compare the taxonomic and functional characteristics of gut microbiomes between ICU staff and non-medical individuals using metagenomic sequencing. A prospective cross-sectional cohort study was conducted, fecal samples from 39 individuals in each group—ICU staff and non-medical subjects were analyzed using metagenomic sequencing. PERMANOVA (using the adonis function) was employed to analyze the genus-level profiles and assess the impact of individual parameters on the gut microbiome. Multiple databases were utilized to annotate and compare the functional differences in gut microbiomes between the two groups. We observed that ICU staff exhibited a significant decrease in gut microbiome diversity, characterized by a marked decline in Actinobacteria and a substantial increase in Bacteroides and Bacteroidaceae. CAZy annotation revealed a notable increase in carbohydrate-active enzymes within the ICU staff cohort. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis further indicated an elevated risk of endocrine and metabolic disorders, along with enhanced glycan biosynthesis and metabolism. Additionally, KEGG pathway enrichment analysis highlighted significant enrichment in cancer-related pathways. Analysis using the Virulence Factor Database (VFDB) showed a higher abundance of virulence factors associated with immune modulation, invasion, and antimicrobial activity/competitive advantage among ICU staff. Notably, no discernible difference in the presence of antibiotic resistance genes within the gut microbiomes was observed between the two groups. Importantly, all aforementioned differences demonstrated clear gender disparities. Our findings indicated that ICU staff exhibited a reduction in gut microbiome diversity which was associated with an increase in virulence factors and carbohydrate-active enzymes, as well as with a heightened susceptibility to endocrine and metabolic diseases and cancers.","PeriodicalId":10811,"journal":{"name":"Critical Care","volume":"96 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744823","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}

Death from hemorrhage occurs rapidly after the initial trauma, in most cases before the patient has had a chance to reach a hospital. Thus, the development of adjuvant drugs that would increase the survival of injured patients is necessary. Among the many avenues of research in this area, one is to improve cell survival during tissue hypoxia. During hemorrhagic shock, oxygen delivery to cells decreases and, despite increased oxygen extraction, anaerobic metabolism occurs, leading to acidosis, coagulopathy, apoptosis, and organ dysfunction. We selected six treatments that may help cells cope with this situation and could be used as adjuvant therapies during the initial resuscitation of severe trauma patients, including out-of-hospital settings: niacin, thiazolidinediones, prolyl hydroxylase domain inhibitors, O-GlcNAcylation stimulation, histone deacetylase inhibitors, and adenosine–lidocaine–magnesium solution. For each treatment, the biological mechanism involved and a systematic review of its interest in hemorrhagic shock (preclinical data and human clinical trials) are presented. Promising molecules, some of which are already used in humans for other indications, give us hope for human clinical trials in the field of hemorrhagic shock in the near future.","PeriodicalId":10811,"journal":{"name":"Critical Care","volume":"11 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143734011","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}
