Background: Acute kidney injury (AKI) is a hidden complication among children within pediatric intensive care units (PICU).

Aim: To evaluate the early predictive and diagnostic value of Urinary [TIMP-2][IGFBP7] to detect AKI in PICU patients.

Methods: A case-control study was conducted on 112 children (72 admitted to PICU and 40 healthy controls) Urinary [TIMP-2][IGFBP7] was measured within 24 hours of PICU admission.

Results: Acute kidney injury developed in 52 (72.2%) out of 72 critically ill patients. The AKI group had significantly higher serum creatinine, CRP, and pediatric sequential organ failure assessment score (pSOFA) score (p = 0.001, 0.01, and 0.001, respectively) and significantly lower estimated creatinine clearance (eCCl) (p = 0.001). Urinary [TIMP-2][IGFBP7] was significantly higher in the AKI group as compared with the non-AKI group (p = 0.007). The duration of the PICU stay was 1.8-fold higher in the AKI group (p = 0.004). At the time of study enrollment, 7 (13.5%) patients had normal initial eCCl. 26 patients (50.0%) fulfilled the "Risk," 18 patients (34.6%) the "Injury," 1 patient (1.9%) the "Failure" and 0 patient (0%) the "Loss" criteria. Nine (17%) patients progressed to the next higher pediatrics risk, injury, failure, loss, end-stage renal disease (pRIFLE) stage. Urinary [TIMP-2][IGFBP7] was significantly higher in the "Failure" stage followed by "Injury," stage then the "Risk," stage (p = 0.001). Hypovolemia/dehydration had the highest [TIMP-2][IGFBP7] values followed by sepsis. Urinary [TIMP-2][IGFBP7] was significantly increased in mechanically ventilated and patients who received inotropic medications.

Conclusions: [TIMP-2]·[IGFBP7] was higher in AKI patients compared with non-AKI ones especially cases with hypovolemia and sepsis. It may predict severe morbidity and mortality because its higher levels in mechanically ventilated children and those on positive inotropic support.

Objectives: To study the efficacy of polymyxin B hemoperfusion in addition to standard care for sepsis treatment.

Materials and methods: Fifty sepsis patients (mean age 54.26 ± 14.64 years; 68% males) were randomized to either the case group (n = 25; receiving Polymyxin B hemoperfusion in addition to standard ICU care) or the control group (n = 25; receiving standard ICU care only). The patients were followed up at frequent intervals of 6, 12, 24, 48, and 72 hours. A last follow-up on day 7 was done. The duration of the ICU stay and survival until day 7 were recorded. Changes in clinical and biochemical parameters were also noted and compared.

Results: Mean sequential organ failure assessment (SOFA) scores at admission were 3.44 ± 1.00 and 2.80 ± 0.82, respectively, in cases and controls. Cases as compared to controls showed faster, and sustainable improvement. No significant difference between the two groups was seen for mortality at day 7.

Conclusion: Polymyxin B hemoperfusion tends to show a faster recovery and a non-significant trend towards reduced mortality in ICU-admitted sepsis patients.

Background: The classification of Berlin definition is based on the PaO₂/FiO₂ ratio, which has been found to have a poor association with mortality. Airway pressures reflect lung compliance and the settings of mechanical ventilators. In this study, we aimed to investigate the change in the severity of COVID-19-associated acute respiratory distress syndrome (ARDS) classification using [PaO₂/FiO₂ × PEEP] (P/FP) ratio compared to the traditional P/F ratio, and whether the P/FP ratio improves the predictive validity of in-hospital mortality.

Methods: Our study sample included patients from the OXIVA-CARDS study. In this secondary analysis, we examined the oxygenation index and oxygen saturation index in relation to the P/FP ratio, as well as the risk of P/FP in mortality. We used Pearson's correlation to assess the relationships between various parameters. Receiver operating characteristic analysis with Youden's index was used to compare the prognostic value of the oxygenation index (OI), oxygen saturation index (OSI), P/F ratio, P/FP ratio, and SaO₂/FiO₂ ratio for predicting overall mortality. Multiple logistic regression was also performed to determine the impact of mean airway pressure (Pmean), S/F ratio, OI, and P/FP ratio on mortality.

Results: A total of 201 patients (with 1543 measurements) were included in the analysis. Overall, 522 (34%) were reclassified into either more or less severe categories. Patients who were classified as having severe ARDS based on the P/FP ratio had significantly lower P/FP ratio, oxygenation index, and A-a O2 gradient as compared to those classified as having severe ARDS based on the P/F ratio (p < 0.05) at all levels of ARDS severity. On multivariate regression analysis, only the OI significantly impacted mortality (p < 0.05).

Conclusion: We observed that the oxygen index and oxygen saturation index were more sensitive than the PaO_2/FiO₂ ratio and P/FP ratio. Additionally, only the oxygenation index had a significant impact on mortality. By including airway pressures in the calculation of the OI, its predictive ability is enhanced compared to using the S/F ratio, P/F ratio, or P/FP ratio.

Highlights: The sensitivity of mortality by including Pmean is higher as compared to when only PEEP is taken into consideration. P/FP is a weak predictor of mortality as compared to OI and OSI.

Introduction: The care of critically ill patients involves communication and shared decision-making with families and determination of goals of care. Analyzing these aspects through electronic health records (EHRs) can support research in ICUs, associating them with outcomes. This review aims to explore studies that examine these topics.

Methods: A scoping review was conducted through a systematic literature search of articles in PubMed, Web of Science, and Embase databases using MESH terms up to 2024, conducted in ICU settings, focusing on communication with families, shared decision-making, goals, and end-of-life care.

Results: A total of 10 articles were included, divided into themes: Records and family, and records in quality improvement projects. Variables based on records with common characteristics were identified. Outcome analysis was performed through questionnaires to family members, healthcare professionals or by analyzing care processes. The studies revealed associations between family members' perceptions and mental health symptoms and documented elements such as communication, therapeutic limitations, social and spiritual support. Studies evaluating quality communication improvement projects did not show significant impact on documented care, except for those that assessed improvements based on palliative care.

Conclusion: The analysis of documented care for critically ill patients can be conducted from various perspectives. Processes amenable to improvement, such as communication with family members, definition of goals of care, limitations, shared decision-making, evaluated through EHRs, are associated with mental health symptoms and perceptions of families of critically ill patients. Documentation-based studies can contribute to improvements in patient- and family-centered care in the ICU.

Background: This study examines the trends of procalcitonin (PCT), neutrophil-to-lymphocyte ratio (NLR), and sequential organ failure assessment (SOFA) scores in intensive care unit (ICU) sepsis patients from different infection sources. Elevations in PCT and NLR reflect infection severity and predict sepsis prognosis. Combining them may enhance diagnostic accuracy and prognostic capabilities, despite variations in cut-off values. The study emphasizes the significance of these biomarkers in improving sepsis management and patient outcomes.

Materials and methods: This was a prospective observation study of ICU sepsis patients from different infection sources. Procalcitonin and NLR levels were measured on days 0, 2, and 4 of admission. Sequential organ failure assessment scores on these days were also analyzed. The cut-off values were obtained for predicting the prognosis of sepsis ICU patients.

Results: The study included 100 sepsis patients with an equal distribution of males and females and a mean age of 72 years. Procalcitonin showed a significant decrease over time, while NLR initially increased before decreasing on day 4, and SOFA scores showed no significant changes. Deceased patients had significantly higher PCT and SOFA scores on days 2 and 4. Receiver operating characteristic curve analysis showed promising predictive results for PCT on day 4 and SOFA scores on days 2 and 4.

Conclusion: Understanding the trends of PCT and NLR concerning the infection source can provide deeper insights into their diagnostic and prognostic capabilities. This comparative analysis of PCT, NLR, and SOFA score trends contributes to the improvement of patient outcomes through accurate assessment of sepsis severity and progression, early diagnosis, and timely intervention.

Background: Sepsis, a life-threatening condition characterized by a dysregulated immune response to infection, remains a significant clinical challenge globally. This study aims to enhance the predictive accuracy of existing sepsis severity scores by developing augmented versions of the SOFA and SAPS-III models, termed Pro-SOFA and Pro-SAPS, through the integration of biomarkers procalcitonin (PCT), neutrophil-to-lymphocyte ratio (NLR), and C-reactive protein (CRP).

Methods: This prospective observational study was conducted in the medical ICU of a tertiary care hospital in southern India from August 2022 to December 2023. A total of 301 adult patients suspected or confirmed to have sepsis were assessed for eligibility, with 171 patients completing the study. Demographic and clinical data were collected; SOFA and SAPS-III scores were calculated and augmented with PCT, NLR, and CRP to develop Pro-SOFA and Pro-SAPS models. The performance of these models was evaluated using Brier scores, AUC, and net reclassification index (NRI).

Results: The augmented Pro-SOFA and Pro-SAPS models demonstrated superior predictive accuracy compared to their original counterparts. The Brier scores for Pro-SOFA and Pro-SAPS were 0.181 and 0.165, respectively, indicating better calibration than the original scores. The Pro-SAPS showed significant improvement over the original SAPS-III score (NRI = 0.50, SE = 0.14, p < 0.01). Similarly, Pro-SOFA outperformed the original SOFA (NRI = 0.49, SE = 0.13, p < 0.01).

Conclusion and clinical significance: Integrating PCT, CRP, and NLR with SOFA and SAPS-III scores to develop Pro-SOFA and Pro-SAPS significantly improves the predictive accuracy for sepsis mortality and can thus potentially improve sepsis outcomes.
