ReviewMachine learning for predicting mortality in adult critically ill patients with Sepsis: A systematic review.
Various Machine Learning (ML) models have been used to predict sepsis-associated mortality. We conducted a systematic review to evaluate the methodologies employed in studies to predict mortality among patients with sepsis. ⋯ ML models demonstrate a modest improvement in predicting sepsis-associated mortality. The certainty of these findings remains low due to the high risk of bias and significant heterogeneity. Studies should include comprehensive methodological details on calibration and hyperparameter selection, adopt a standardized definition of sepsis, and conduct multicenter prospective designs along with external validations.

Observational StudyPharmacokinetic Factors Associated With Early Meropenem Target Attainment in Pediatric Severe Sepsis.
To determine the frequency of early meropenem concentration target attainment (TA) in critically ill children with severe sepsis; to explore clinical, therapeutic, and pharmacokinetic factors associated with TA; and to assess how fluid resuscitation and volume status relate to early TA. ⋯ Eight of 29 pediatric patients with early severe sepsis did not meet the selected TA threshold within the first 24 hours of meropenem therapy. Higher clearance was associated with failure to meet targets. Identifying patients likely to have higher meropenem clearance could help with dosing regimens.

Sepsis is a potentially life-threatening condition that eventually causes multiorgan dysfunction in critically ill patients. Acute kidney injury (AKI) is a severe life-threatening complication of sepsis, a condition termed sepsis-induced AKI (S-AKI), with poor clinical outcomes and high mortality rates. Inflammatory and immunological responses are important variables in S-AKI. This study aimed to examine the relationship of rs1518111 polymorphism in the interleukin-10 ( IL-10 ) gene and serum/urine IL-10 levels with sepsis-induced AKI in critically ill patients in the intensive care unit (ICU). ⋯ rs1518111 polymorphism in the IL-10 gene is a risk factor for sepsis-induced AKI in the ICU. Serum/urine IL-10 levels may be used as predictors of S-AKI in critically ill patients with sepsis, thereby improving early management.

Central venous saturation (ScvO 2 ) can guide resuscitation of children with septic shock. The normal range of ScvO 2 is typically considered as 0.70-0.80, but has not been established in children with cancer. Children with cancer are particularly prone to develop sepsis due to their immunosuppressive therapy, and usually have a permanent central venous catheter, making ScvO 2 readily available. We aimed to investigate normal values of ScvO 2 in clinically stable children with cancer, and the association between ScvO 2 , hemoglobin, and lactate. ⋯ The study revealed that a substantial portion of clinically stable childhood cancer patients exhibited ScvO 2 levels below the typical reference value of 0.70, suggesting that these children may have inherently lower baseline ScvO 2 levels. This should be kept in mind when evaluating children with cancer for septic shock, emphasizing the importance of tailored assessments in this population. Further understanding of baseline ScvO 2 abnormalities may be helpful if ScvO 2 is used to guide resuscitation.

Background : Previous preclinical studies have demonstrated a pathobiome after traumatic injury; however, the impact of postinjury sepsis on gut epithelial permeability and bacterial translocation remains unknown. We hypothesized that polytrauma with postinjury pneumonia would result in impaired gut permeability leading to specific blood microbiome arrays. Methods : Male and proestrus female Sprague-Dawley rats were subjected to either polytrauma (PT), PT plus 2-hours daily chronic restraint stress (PT/CS), PT with postinjury day 1 inoculation with pseudomonas pneumonia (PT + PNA), PT/CS + PNA, or naive controls. ⋯ Females PT/CS + PNA had a significant abundance of Staphylococcus at day 2 and Streptococcus at day 7 in the blood biome compared to male counterparts ( P < 0.05). Conclusion : Multicompartmental trauma with postinjury pneumonia results in increased intestinal permeability and bacteremia with a unique blood biome, with sexual dimorphisms evident in the blood biome composition. These findings suggest that postinjury sepsis has clinical significance and could influence outcomes after severe trauma and critical illness.
