Host Response Stratification in Malarial and Non-malarial Sepsis: A Prospective, Multicenter Analysis From Uganda.
Globally, the burden of sepsis is highest in malaria endemic areas of sub-Saharan Africa. The influence of malaria on biological heterogeneity inherent to sepsis in this setting is poorly understood. We sought to determine shared and distinct features of the host response in malarial and non-malarial sepsis in sub-Saharan Africa. ⋯ Host responses are largely conserved in malarial and non-malarial sepsis but may be distinguished by a signature of relative immunosuppression in the former. Further investigations are needed to differentiate mechanisms of malarial and non-malarial sepsis, with the goal of informing pathogen-stratified and pathogen-agnostic treatment strategies.

Prediction of Intensive Care Length of Stay for Surviving and Nonsurviving Patients Using Deep Learning.
Length of stay (LOS) models support evaluating ICU care; however, current benchmarking models fail to consider differences in LOS between surviving and nonsurviving patients, which can lead to biased predictions toward the surviving population. We aim to develop a model addressing this as well as documentation bias to improve ICU benchmarking. ⋯ This novel LOS model represents a step forward in achieving more equitable benchmarking across diverse ICU settings with varying risk profiles.

Association of Omega-3 Status With Long-Term Risk of Hospitalization for Sepsis.
Sepsis is a life-threatening condition characterized by a dysregulated host response to infection. Despite decades of clinical trials, there are no specific treatments; care of the nearly 50 million annual cases worldwide is limited to antimicrobials and supportive measures. A primary prevention strategy may therefore be of value. We hypothesized that higher premorbid omega-3 fatty acid levels would be associated with a reduced incidence of sepsis. ⋯ In this population-based cohort study, baseline eO3I was inversely associated with subsequent sepsis incidence. Given that omega-3 levels can be increased with dietary supplementation, primary prevention should be explored to mitigate the burden of sepsis.
