Definition of sepsis and septic shock

PURPOSE: Nowadays, it is largely accepted that albumin should not be used in hypoalbuminemia or for nutritional purpose. The most discussed indication of albumin at present is the resuscitation in shock states, especially distributive shocks such as septic shock. The main evidence-based indication is also liver disease. In this review, we provided updated evidence-based instruction for definite and potential indications of albumin administration in clinical practice, with appropriate dosing and duration...

OBJECTIVES: This study aimed to assess the diagnostic, risk stratification, and prognostic capabilities of apelin-13 and APJ in comparison to procalcitonin (PCT) for septic patients presenting to the emergency department (ED). METHODS: Two hundred and thirty-eight patients meeting the Third International Consensus Definition (Sepsis-3) criteria were enrolled from Beijing Chaoyang Hospital's ED, along with a control group of forty healthy individuals. Patients were categorized into two groups based on disease severity: those with sepsis or septic shock...

BACKGROUND: Escherichia coli is the most frequent cause of bloodstream infections (BSIs). About one-third of patients with BSIs due to E coli develop sepsis or shock. The objective of this study is to characterise the microbiological features of E coli blood isolates causing sepsis or septic shock to provide exploratory information for future diagnostic, preventive, or therapeutic interventions. METHODS: E coli blood isolates from a multicentre cross-sectional study of patients older than 14 years presenting with sepsis or septic shock (according to the Third International Consensus Definitions for Sepsis and Septic Shock criteria) from hospitals in Spain between Oct 4, 2016, and Oct 15, 2017, were studied by whole-genome sequencing...

BACKGROUND: Since the 1990's attempts to favorably modulate nitric oxide (NO) have been unsuccessful. We hypothesized that because NO is lipophilic it would preferentially localize into intravascularly infused hydrophobic nanoparticles, thereby reducing its bioavailability and adverse effects without inhibiting its production. We aimed to determine the efficacy and safety of intravenous infusion of a fluid comprised of hydrophobic phospholipid nanoparticles (VBI-S) that reversibly absorb NO in the treatment of hypotension of patients in severe septic shock...

Background and Objectives : According to the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3), sepsis is defined as "life-threatening organ dysfunction caused by a dysregulated host response to infection". The increased presence of free radicals causes an increase in oxidative stress. Vitamin C is an essential water-soluble vitamin with antioxidant activity and immunoregulatory effects that plays a potential role in the treatment of bacterial infections. Our aim was to evaluate the effectiveness of adding vitamin C to the conventional treatment of sepsis to decrease its mortality rate...

Worldwide, sepsis is a well-recognized cause of death. Acute kidney injury (AKI) may be related to sepsis in up to 70% of AKI cases. Sepsis-associated AKI (SA-AKI) is defined as the presence of AKI according to the Kidney Disease: Improving Global Outcomes criteria in the context of sepsis. SA-AKI is categorized into early, which presents during the first 48 h of sepsis, and late, presenting between 48 h and 7 days of sepsis. SA-AKI is associated with a worse prognosis among patients with sepsis. However, there are different SA-AKI phenotypes as well as different pathophysiological pathways of SA-AKI...

BACKGROUND: Tuberculous sepsis is uncommon in individuals without human immunodeficiency virus (HIV) infection, and some patients may not exhibit clinical signs and symptoms of suspected sepsis upon admission, leading to delayed diagnosis and treatment. CASE PRESENTATION: This report present the case of a 60-year-old female patient who presented with erythema, edema, and pain in her right upper limb accompanied by fever and chills. Further evaluation revealed multiple intermuscular abscesses caused by suspected gram-positive bacteria...

BACKGROUND: The Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is highly transmissible but causes less severe disease compared to other variants. However, its association with sepsis incidence and outcomes is unclear. This study aimed to investigate the incidence of Omicron-associated sepsis, as per the Sepsis 3.0 definition, in hospitalized patients, and to explore its relationship with clinical characteristics and prognosis. METHODS: This multicenter retrospective study included adults hospitalized with confirmed SARS-CoV-2 infection across six tertiary hospitals in Guangzhou, China from November 2022 to January 2023...

BACKGROUND: Paediatric sepsis is the leading cause of death in children under 5 years. No studies have evaluated the application of the Surviving Sepsis Campaign 2020 (SSC-2020) guidelines in paediatric emergency departments (PEDs). OBJECTIVE: To assess physician adherence to the SSC-2020 fluid resuscitation guidelines in children with suspected septic shock in PEDs. METHODS: This was a prospective multicentre observational study conducted in 21 French hospitals over 5 sequential weeks, between November 2021 and March 2022...

BACKGROUND: Data to support the use of specific vasopressors in septic shock are limited. Since angiotensin II (AT2) was approved by the Food and Drug Administration in 2017, multiple mechanistically distinct vasopressors are available to treat septic shock, but minimal data exist regarding which patients are most likely to benefit from each agent. Renin and dipeptidyl peptidase 3 (DPP3) are components of the renin-angiotensin-aldosterone system which have been shown to outperform lactate in predicting sepsis prognosis, and preliminary data suggest they could prove useful as biomarkers to guide AT2 use in septic shock...

The main clinical research advances of critical care in 2023 includes: new trials of Chinese herbal medicine, hydroxocobalamin (vitamin B12), methylene blue as well glucocorticoids have shown the potential to improve outcomes of patients with sepsis and septic shock; international committees launched new global definition and managing recommendations for acute respiratory distress syndrome (ARDS). Besides, a cluster of new evidences has emerged in many aspects as following: fluid control strategy in sepsis (restrictive/liberative), antibiotic infusion strategy (continuous/intermittent), oxygen-saturation targets for mechanical ventilation (conservative/liberative), blood pressure targets after resuscitation from out-of-hospital cardiac arrest (hypotension/hypertension), blood pressure targets after successful stroke thrombectomy (intensive/conventional), and nutritional support strategies (low protein-calories/conventional protein-calories, fasting/persistent feeding before extubation)...

Sex differences in the in-hospital management of sepsis exist. Previous studies either included patients with sepsis that was defined using previous definitions of sepsis or evaluated the 3-h bundle therapy. Therefore, this study sought to assess sex differences in 1-h bundle therapy and in-hospital management among patients with sepsis and septic shock, defined according to the Sepsis-3 definitions. This observational study used data from Korean Shock Society (KoSS) registry, a prospective multicenter sepsis registry...

BACKGROUND AND OBJECTIVE: The diagnosis of infection, to diagnose septic shock, has been qualified by leukocyte counts and protein biomarkers. Septic shock mortality is persistently high (20%-50%), and rising in the long term. The definition of sepsis does not include leukocyte count, and lymphopenia has been associated with its mortality in the short term. Immunosuppression and increased mortality in the long term due to sepsis have not been demonstrated. The aim is to relate the occurrence of lymphopenia and its lack of recovery during septic shock with mortality at 2 years...

Arterial-enteric fistulas occur from a multitude of causes, especially following surgical manipulation of vasculature. The development of an iliac artery-enteric fistula (IEF) occurs rarely in patients with failed pancreatic transplants. IEFs warrant urgent intervention due to the high mortality from hemorrhagic and septic shock. The diagnosis can be delayed by a lack of suspicion, the low sensitivity of diagnostic tests, and the nonspecific signs of fistulas on computed tomography. The management of IEFs is adapted from guidelines for arterial-enteric fistulas of other causes, with little consensus on ideal vascular reconstruction and postoperative antimicrobial management...

BACKGROUND: The early identification of sepsis presenting a high risk of deterioration is a daily challenge to optimise patient pathway. This is all the most crucial in the prehospital setting to optimize triage and admission into the appropriate unit: emergency department (ED) or intensive care unit (ICU). We report the association between the prehospital National Early Warning Score 2 (NEWS-2) and in-hospital, 30 and 90-day mortality of SS patients cared for in the pre-hospital setting by a mobile ICU (MICU)...

IMPORTANCE: The Society of Critical Care Medicine Pediatric Sepsis Definition Task Force sought to develop and validate new clinical criteria for pediatric sepsis and septic shock using measures of organ dysfunction through a data-driven approach. OBJECTIVE: To derive and validate novel criteria for pediatric sepsis and septic shock across differently resourced settings. DESIGN, SETTING, AND PARTICIPANTS: Multicenter, international, retrospective cohort study in 10 health systems in the US, Colombia, Bangladesh, China, and Kenya, 3 of which were used as external validation sites...

IMPORTANCE: Sepsis is a leading cause of death among children worldwide. Current pediatric-specific criteria for sepsis were published in 2005 based on expert opinion. In 2016, the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) defined sepsis as life-threatening organ dysfunction caused by a dysregulated host response to infection, but it excluded children. OBJECTIVE: To update and evaluate criteria for sepsis and septic shock in children...

BACKGROUND: Neonatal sepsis remains a leading cause of mortality in neonatal units. Neonatologist-performed echocardiography (NPE) offers the potential for early detection of sepsis-associated cardiovascular dysfunction. This review examines available echocardiographic findings in septic neonates. METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we systematically reviewed prospective observational, cross-sectional, case control, and cohort studies on septic newborns with echocardiographic assessments from PubMed, Scopus and Embase...

BACKGROUND: The Sepsis-3 guidelines have incorporated serum lactate levels of >2 mmol/L in septic shock definition to account for higher observed mortality. Further evidence is needed to support this threshold in cirrhosis, as well as target mean arterial pressure (MAP) during resuscitation. METHODS: This observational cohort study investigated the association between initial serum lactate and resuscitation MAP levels on in-hospital mortality in patients with and without cirrhosis...

Dealing with acute cholecystitis in high-risk, critically ill, and unfit-for-surgery patients is frequent during daily practice and requires complex management. Several procedures exist to postpone and/or prevent surgical intervention in those patients who temporarily or definitively cannot undergo surgery. After a systematic review of the literature, an expert panel from the Italian Society of Emergency Surgery and Trauma (SICUT) discussed the different issues and statements in subsequent rounds. The final version of the statements was discussed during the annual meeting in Rome (September 2022)...
