- Abstract
BACKGROUND: Data on long-term outcomes after sepsis-associated critical illness have mostly come from small cohort studies, with no information about the incidence of new disability. We investigated whether sepsis-associated critical illness was independently associated with new disability at 6 months after ICU admission compared with other types of critical illness. METHODS: We conducted a secondary analysis of a multicenter, prospective cohort study in six metropolitan intensive care units in Australia. Adult patients were eligible if they had been admitted to the ICU and received more than 24 h of mechanical ventilation. There was no intervention. RESULTS: The primary outcome was new disability measured with the WHO Disability Assessment Schedule 2.0 (WHODAS) 12 level score compared between baseline and 6 months. Between enrollment and follow-up at 6 months, 222/888 (25%) patients died, 100 (35.5%) with sepsis and 122 (20.1%) without sepsis (P < 0.001). Among survivors, there was no difference for the incidence of new disability at 6 months with or without sepsis, 42/106 (39.6%) and 106/300 (35.3%) (RD, 0.00 (- 10.29 to 10.40), P = 0.995), respectively. In addition, there was no difference in the severity of disability, health-related quality of life, anxiety and depression, post-traumatic stress, return to work, financial distress or cognitive function. CONCLUSIONS: Compared to mechanically ventilated patients of similar acuity and length of stay without sepsis, patients with sepsis admitted to ICU have an increased risk of death, but survivors have a similar risk of new disability at 6 months.

- Abstract
Receptor-interacting serine/threonine-protein kinase 1 (RIPK1) has a crucial role in cell death and inflammation. A promising approach to develop novel inhibitors of RIPK1 mediated necroptosis is to mix the different binding modes of the known RIPK1 inhibitors into one molecule. Herein we report the synthesis and biological evaluation of novel mixed type inhibitors. Using Eclitasertib as a starting point, and applying our previous, published knowledge regarding cyclic malonamides, we successfully identified a library of active compounds. The active enantiomer of the most balanced and promising compound was subjected to pharmacokinetics and in vivo hypothermia study in mice., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

- Abstract
Receptor-interacting serine/threonine-protein kinase 1 (RIPK1) plays a key role in cell death and inflammation. RIPK1 is a well-established therapeutic target, due to the presence of a unique kinase-regulating allosteric pocket, which enables selective inhibition. Herein we used GSK2982772 as our starting point in our discovery campaign. Applying isosteric replacement, we successfully identified the malonamide scaffold, instead of the well-established serine template. Further structural optimization led to the design and synthesis of a series of analog inhibitors. The enantiomers of the most promising compound were tested on 97 different kinases. The active enantiomer proved to be kinase selective., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

- Abstract
Objectives: The 12-item World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) provides a standardised method for measuring health and disability. This study aimed to determine its reliability, validity and responsiveness and to establish the minimum clinically important difference (MCID) in critically ill patients. Design: Prospective, multicentre cohort study. Setting: Intensive care units of six metropolitan hospitals. Participants: Adults mechanically ventilated for > 24 hours. Main outcome measures: Reliability was assessed by measuring internal consistency. Construct validity was assessed by comparing WHODAS 2.0 scores at 6 months with the EuroQoL visual analogue scale (EQ VAS) and Lawton Instrumental Activities of Daily Living (IADL) scale scores. Responsiveness was evaluated by assessing change over time, effect sizes, and percentage of patients showing no change. The MCID was calculated using both anchor and distribution-based methods with triangulation of results. Main results: A baseline and 6-month WHODAS 2.0 score were available for 448 patients. The WHODAS 2.0 demonstrated good correlation between items with no evidence of item redundancy. Cronbach α coefficient was 0.91 and average split-half coefficient was 0.91. There was a moderate correlation between the WHODAS 2.0 and the EQ VAS scores ( r = -0.72; P < 0.001) and between the WHODAS 2.0 and the Lawton IADL scores ( r = -0.66; P < 0.001) at 6 months. The effect sizes for change in the WHODAS 2.0 score from baseline to 3 months and from 3 to 6 months were low. Ceiling effects were not present and floor effects were present at baseline only. The final MCID estimate was 10%. Conclusion: The 12-item WHODAS 2.0 is a reliable, valid and responsive measure of disability in critically ill patients. A change in the total WHODAS 2.0 score of 10% represents the MCID., Competing Interests: None declared., (© 2021 College of Intensive Care Medicine of Australia and New Zealand.)

- Abstract
Background: Establishing sequela following critical illness is a public health priority; however, recruitment and retention of this cohort make assessing functional outcomes difficult. Completing patient-reported outcome measures (PROMs) via telephone may improve participant and researcher involvement; however, there is little evidence regarding the correlation of PROMs to performance-based outcome measures in critical care survivors., Objectives: The objective of this study was to assess the relationship between self-reported and performance-based measures of function in survivors of critical illness., Methods: This was a nested cohort study of patients enrolled within a previously published study determining predictors of disability-free survival. Spearman's correlation (r
s ) was calculated between four performance-based outcomes (the Functional Independence Measure [FIM], 6-min walk distance [6MWD], Functional Reach Test [FRT], and grip strength) that were collected during a home visit 6 months following their intensive care unit admission, with two commonly used PROMs (World Health Organization Disability Assessment Scale 2.0 12 Level [WHODAS 2.0] and EuroQol-5 Dimension-5 Level [EQ-5D-5L]) obtained via phone interview (via the PREDICT study) at the same time point., Results: There were 38 PROMs obtained from 40 recruited patients (mean age = 59.8 ± 16 yrs, M:F = 24:16). All 40 completed the FIM and grip strength, 37 the 6MWD, and 39 the FRT. A strong correlation was found between the primary outcome of the WHODAS 2.0 with all performance-based outcomes apart from grip strength where a moderate correlation was identified. Although strong correlations were also established between the EQ-5D-5L utility score and the FIM, 6MWD, and FRT, it only correlated weakly with grip strength. The EQ-5D overall global health rating only had very weak to moderate correlations with the performance-based outcomes., Conclusion: The WHODAS 2.0 correlated stronger across multiple performance-based outcome measures of functional recovery and is recommended for use in survivors of critical illness., (Copyright © 2022 Australian College of Critical Care Nurses Ltd.

- Abstract
Purpose: To compare the effect of conservative vs. liberal oxygen therapy in mechanically ventilated adults in the intensive care unit (ICU) with non-hypoxic ischemic encephalopathy (HIE) acute brain pathologies., Materials and Methods: Post-hoc analysis of data from 217 patients with non-HIE acute brain pathologies included in the ICU Randomized Trial Comparing Two Approaches to OXygen therapy (ICU-ROX)., Results: Patients allocated to conservative oxygen spent less time with oxygen saturation ≥ 97% (50.5 [interquartile range (IQR), 18.5-119] vs. 82 h [IQR, 38-164], absolute difference, -31.5 h; 95%CI, -59.6 to -3.4). At 180 days, 38 of 110 conservative oxygen patients (34.5%) and 28 of 104 liberal oxygen patients (26.9%) had died (absolute difference, 7.6 percentage points; 95%CI, -4.7 to 19.9 percentage points; P = 0.23; interaction P = 0.02 for non-HIE acute brain pathologies vs. HIE; interaction P = 0.53 for non-HIE acute brain pathologies vs. non-neurological conditions)., Conclusions: In this post-hoc analysis, patients admitted to the ICU with non-HIE acute brain pathologies treated with conservative oxygen therapy did not have significantly lower mortality than those treated with liberal oxygen. A trial with adequate statistical power is needed to determine whether our day 180 mortality point estimate of treatment effect favoring liberal oxygen therapy indicates a true effect., (Copyright © 2022 Elsevier Inc.
