After adjusting for confounders, LA had a greater effect on AKI risk in SS patients (hazard ratio (HR) = 1.056 versus 1.05 in HS), whereas LA more strongly influenced IMR in HS patients (HR = 1.115 vs 1.08 in SS). The safe LA thresholds, where HR = 1, were 2.083 mmol/L for SS and 2.31 mmol/L for HS. KM analysis demonstrated significant differences in cumulative AKI incidence and IMR among different LA levels (Log-rank P < .001). In HS patients, AKI risk increased linearly with rising LA, reflecting cumulative hypoperfusion. In SS patients, AKI risk rose sharply at lower LA levels, likely due to the inflammatory cytokine storm. ROC analysis showed that LA improved the predictive performance of the Acute Physiology Score III (APSIII) and the Simplified Acute Physiology Score II (SAPSII), particularly in HS patients. The change in area under the curve (ΔAUC) of SAPSII for predicting IMR was +0.042 in HS and +0.013 in SS.ConclusionsLA is a key predictor of AKI risk and prognosis in HS or SS patients, and its impact is heterogeneous among different populations, suggesting that individualized monitoring thresholds are needed.</p>","PeriodicalId":16307,"journal":{"name":"Journal of Intensive Care Medicine","volume":" ","pages":"830-844"},"PeriodicalIF":2.3,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145944535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study intentionally used a broader CT-based definition encompassing necrotizing pneumonia, lung abscess and necrotizing cavitation to capture the clinically relevant spectrum of destructive pulmonary complications observed in critically ill ECMO patients.

The high proportion of viral pneumonia, particularly COVID-19, concomitant thromboembolic events, corticosteroid exposure and severe ventilation/perfusion abnormalities likely contributed to the high incidence of necrotic complications observed in our cohort.

The objective of this study was to evaluate the efficacy and safety of enteral clonidine in the transition from dexmedetomidine for agitation and sedation in the intensive care unit (ICU).Materials and MethodsThis was a single-center, retrospective cohort study of adult patients admitted to an ICU at UMass Memorial Medical Center between May 1, 2022 to April 30, 2023 who received enteral clonidine for the indication of weaning dexmedetomidine. The primary outcome was discontinuation of dexmedetomidine within 24 h of starting enteral clonidine. A priori risk factors for the primary outcome included duration of dexmedetomidine prior to clonidine initiation, clonidine total daily dose, average Richmond Agitation-Sedation Scale (RASS) and Sequential Organ Failure Assessment (SOFA) scores, history of a psychiatric disorder, intubation at time of clonidine initiation, and being on additional sedation agents at the time of clonidine initiation. Safety outcomes included the incidence of bradycardia, hypotension, and withdrawal.ResultsSeventy-three patients were included. The primary outcome of dexmedetomidine discontinuation within 24 h occurred in 38 patients (52%). Multivariable logistic regression analysis of the a priori risk factors indicated that non-intubated patients at the time of clonidine initiation were significantly more likely to achieve the primary outcome (OR 4.27, 95% CI 1.04-17.62, p = 0.04). Incidence of bradycardia (5% clonidine vs 16% dexmedetomidine, p = 0.04) and withdrawal (0% vs 49%, p < 0.0001) were higher while patients were on dexmedetomidine.ConclusionsClonidine was efficacious in weaning dexmedetomidine within 24 h in 52% of patients; however, the ideal dose and period for initiation remains unclear.

Traditional coagulation assays such as prothrombin time (PT) and activated partial thromboplastin time (aPTT) primarily assess the initiation of clot formation but fail to capture the dynamic balance between procoagulant and anticoagulant forces. The thrombin generation (TG) assay provides a more comprehensive evaluation of coagulation, incorporating both propagation and decay phases, and may offer additional insight into sepsis-associated coagulopathy. This study investigated the diagnostic and prognostic utility of TG parameters across graded stages of DIC in septic intensive care unit (ICU) patients.MethodsIn this prospective observational study, 53 adult septic ICU patients contributed 151 plasma samples obtained longitudinally. Patients were classified as non-DIC, non-overt DIC, or overt DIC according to International Society on Thrombosis and Haemostasis criteria. Standard coagulation parameters and TG profiles were measured. Associations with DIC severity were examined using cumulative link mixed models with patient-level random effects. Sensitivity analyses explored transition-specific TG behavior. ICU mortality was evaluated using multivariable logistic regression and ROC analysis.ResultsIn univariate analyses, both conventional coagulation markers and TG parameters were associated with increasing DIC severity. In the final multivariable model, prolonged PT and aPTT, elevated D-dimer, and lower platelet count were the strongest independent predictors of DIC severity, whereas StartTail provided complementary kinetic information. Longitudinal analyses demonstrated progressive prolongation of StartTail and attenuation of reverse velocity index with advancing DIC stage and increasing SOFA scores, indicating worsening dysregulation of thrombin inactivation.ConclusionTG parameters, particularly late-phase kinetic features, reflect dynamic and stage-specific dysregulation of coagulation in sepsis-associated DIC.

The inflammatory response following TBI plays a crucial role in patient outcomes, presenting both protective and potentially detrimental effects. This narrative review examines the current evidence regarding the role of nutritional supplements in modulating the inflammatory response after TBI. Recent research has demonstrated that various nutritional interventions, including probiotics, immunonutrition formulas, vitamin D, and taurine supplementation, can significantly influence inflammatory markers and clinical outcomes. Probiotics have shown particular promise in reducing inflammatory mediators and infection rates, while also decreasing hospital and ICU length of stay. Immunonutrition, especially through vitamin D supplementation, demonstrates significant effects on consciousness levels and ventilation requirements. The timing of nutritional intervention emerges as critical, with the early post-injury period (24-72 h) representing a crucial window for therapeutic intervention. The gut-brain axis appears central to these effects, with nutritional supplements potentially modulating both central and systemic inflammatory responses. While these interventions show promising results in reducing inflammatory markers and improving short-term outcomes, their impact on mortality rates remains limited. Future research should focus on optimizing nutritional protocols, understanding individual patient factors, and investigating long-term functional outcomes.
