Background: Sepsis has a high prevalence, mortality-rate and cost. Sepsis patients usually enter the hospital through the Emergency Department (ED). Process or structural issues related to care may affect outcome.
Methods: Multi-centered retrospective observational cohort study using administrative databases to identify adult patients (> = 18 years) with sepsis and severe sepsis admitted to Alberta Health Services Calgary zone adult multisystem intensive care units (ICU) through the ED between January 1, 2006 and September 30, 2009. We examined the association between ICU occupancy and hospital outcome. We explored other associations of hospital outcome including the effect of ED wait time, admission from ED during weekdays versus weekends and ED admission during the day versus at night.
Results: One thousand and seven hundred seventy patients were admitted to hospital via ED, 1036 (58.5 %) with sepsis and 734 (41.5 %) with severe sepsis. In patients with sepsis, ICU occupancy > 90 % was associated with an increase in hospital mortality even after adjusting for age, sex, triage level, Charlson index, time of first ED physician assessment and ICU admission. No differences in hospital mortality were found for patients who waited more than 7 h, were admitted during the day versus night or weekdays versus weekends.
Conclusions: In patients with sepsis admitted via the ED, increased ICU occupancy was associated with higher in-hospital mortality.

Impact of hemoadsorption with CytoSorb® on meropenem and piperacillin exposure in critically ill patients in a post-CKRT setup: a single-center, retrospective data analysis.

Purpose: CytoSorb® (CS) adsorbent is a hemoadsorption filter for extracorporeal blood purification often integrated into continuous kidney replacement therapy (CKRT). It is primarily used in critically ill patients with sepsis and related conditions, including cytokine storms and systemic inflammatory responses. Up to now, there is no evidence nor recommendation for the use of CS filters in sepsis (22).

Background: The pathogenesis of sepsis is thought to be linked to a dysregulated immune response, particularly that involving neutrophils. We have developed a granulocyte adsorption column as a "decoy organ," which relocates the massive inflammation in organs in the body to a blood purification column. This study was conducted to assess the safety and experimental effectiveness of granulocyte monocyte adsorption apheresis-direct hemoperfusion (G1-DHP) in the treatment of patients with sepsis, using a prospective, multicenter design.

Background: Management of persistent inflammation, immunosuppression, and catabolism syndrome (PICS) after sepsis remains challenging for patients in the intensive care unit, experiencing poor quality of life and death. However, immune-cell signatures in patients with PICS after sepsis remain unclear.
Methods: We determined immune-cell signatures of PICS after sepsis at single-cell resolution.

Introduction: While various factors leading to prolonged length of stay (LOS) have been identified for emergency general surgery (EGS), there is limited literature on specific factors for individual emergent specialties. This study aimed to identify patient factors and in-hospital complications associated with prolonged LOS for gastrointestinal (GI) and non-GI-related EGS presentations in a low-resource setting.
Methods: Data from 2010 to 2019 were retrieved from one of the largest tertiary care centers in Pakistan.

Sepsis is a common systemic infectious disease followed by extremely high incidence and mortality with no effective treatment and clinical drugs. As a key mediator involved in infection and immunity, it has been reported that sepsis patients are accompanied by increased heat shock protein 70 (HSP70). Trained immunity is a novel innate immunity approach that can be activated by β-glucan to fight against sepsis.
