Article Abstract
Background: Early diagnosis, precise antimicrobial treatment and subsequent patient stratification can improve sepsis outcomes. Circulating biomarkers such as plasma microRNAs (miRNAs) have proven to be surrogates for diagnosis, severity and case management of infections. The expression of four selected miRNAs (miR-146-3p, miR-147b, miR-155 and miR-223) was validated for their prognostic and diagnostic potential in a clinically defined cohort of patients with sepsis and septic shock.
Methods: The expression of plasma miRNAs was quantified by quantitative PCR (qPCR) in patients with bacterial sepsis (n = 78), in patients with septic shock (n = 52) and in patients with dengue haemorrhagic fever (DHF; n = 69) and in healthy controls (n = 82).
Results: The expression of studied miRNA was significantly increased in patients with bacterial sepsis and septic shock. The plasma miR-147b was able to differentiate bacterial sepsis from non-sepsis and septic shock (AUC = 0.77 and 0.8, respectively, p≤ 0.05), while the combination of plasma miR-147b and procalcitonin (PCT) predicted septic shock (AUC = 0.86, p≤ 0.05).
Conclusions: The plasma miR-147b may be an useful biomarker independently or in combination with PCT to support clinical diagnosis of sepsis and equally prognosis of patients with septic shock.

Extracorporeal blood purification (EBP) is an emerging technique for reducing elevated levels of inflammatory mediators and/or endotoxins in critically ill patients with sepsis or other hyperinflammatory conditions. The oXiris filter combines endotoxin adsorption, cytokine adsorption, hemofiltration and anti-thrombosis, and an emerging body of evidence demonstrates its use in critical care patients with hyperinflammatory conditions and acute kidney injury (AKI). A group of Asia-Pacific experts convened to formulate consensus statements for the use of the oXiris filter based on a comprehensive review of publications.

Objective: To review the timing of death in children with sepsis referred for intensive care, 2018-2023, and compare with our previous 2005-2011 practice. We hypothesized that most deaths occur within 24 hours of referral to the PICU, with many before PICU admission.
Design, Setting, And Patients: We reviewed referrals to the Children's Acute Transport Service (CATS), North Thames regional pediatric intensive care transport service in the United Kingdom, between January 2018 and March 2023.
From Evidence to Bedside: The Role of Short-Acting β-Blockers in Sepsis Care.

Sepsis remains a leading cause of critical illness and mortality worldwide, driven by a dysregulated host response to infection and often complicated by persistent tachycardia and cardiovascular dysfunction. Increasing evidence implicates excessive sympathetic activation as a contributor to sepsis-related hemodynamic instability and myocardial injury, prompting growing interest in the use of β-adrenergic blockade as a therapeutic adjunct. This review synthesizes current data on the safety and efficacy of short-acting, cardioselective β-blockers (BBs), particularly esmolol and landiolol, in septic shock.

Objective: Vitamin C has been linked to alterations in platelet count and aggregation behavior. Given recent findings suggesting an association between vitamin C and adverse outcomes in patients with septic shock, we aimed to investigate whether vitamin C influences mortality in septic patients through its impact on platelets.
Design: Post hoc analysis of the Lessening Organ Dysfunction With Vitamin C (LOVIT) randomized trial (clinicaltrials.

Background: Shock, characterised by circulatory hypoperfusion and cellular hypoxia, represents a critical medical condition requiring immediate attention. Despite its significance, there are limited data on shock incidence and outcomes, particularly within the context of Thailand.
Objectives: This retrospective observational study aimed to investigate the incidence, management and outcomes of shock patients admitted to the internal medicine department of Siriraj Hospital, a referral university hospital in Bangkok, Thailand.
