Evolution of Muscle Function, Breathlessness and Quality of Life Following Intra or Extra-Abdominal...
SepsisSeptic ShockSepsis is organ dysfunction secondary to an inappropriate host response to infection. In the most severe cases, circulatory failure necessitating the introduction of vasopressor therapy is called septic shock. Sepsis and septic shock are life-threatening systemic organ dysfunctions requiring hospitalization in a critical care unit. According to several studies, sepsis accounts for around 30% of patients in these units. In this patient population, mortality in the critical care unit or in hospital is 25.8% and 35.3% respectively. Among the organ dysfunctions associated with sepsis, striated skeletal muscle damage is frequent and possibly severe. The literature refers to this as sepsis-induced myopathy, and describes three main mechanisms: mitochondrial dysfunction, exacerbated proteolysis and altered muscle membrane excitability. Of all the striated skeletal muscles that can be affected, the diaphragm and the muscles of the thoracic and abdominal wall play a major role in breathing. The diaphragm remains the main muscle involved in breathing. Its physiology is twofold. Firstly, through its contraction, the diaphragm is responsible for the lateral movement of the lower ribs, thus increasing the transverse diameter of the thorax. This first action is commonly referred to as "insertional". At the same time, lowering the phrenic center of the diaphragm increases abdominal pressure. Its distinctive upwardly convex domed appearance means that it is intimately in contact with both the chest wall and the abdominal cavity. This particular area of contact is called the apposition zone. It is on this zone, under the action of the abdominal compartment, that positive pressure also generates an outward thrust from the medial face of the lower ribs, a second action commonly referred to as "appositional". A number of studies, including that carried out by our team (US_DIAMONDS, NCT 02474797), have identified a high prevalence of diaphragmatic damage in patients with sepsis or septic shock. This can be as high as 60%. This diaphragmatic dysfunction would then be associated with a higher mortality rate in hospital and at D90 of discharge. The clinical evolution of post-resuscitation patients remains a little-studied subject. However, patients may present muscle dysfunctions in the longer term after a stay in intensive care. In our study, we demonstrated that less than half of patients recovered from diaphragmatic dysfunction on discharge from the critical care unit. In addition, Borges RC et al. found a significant decrease in the cross-sectional area of the rectus femoris at discharge, compared with the same measurement taken at D+2 of admission to the critical care unit. Finally, the impact of muscle dysfunction on dyspnoea during sepsis and after its resolution is uncertain. Similarly, the impact of muscle dysfunction and dyspnoea on quality of life is unknown. Sepsis is associated with muscle dysfunction of multiple mechanisms. The aim of this study is to assess the immediate and longer-term impact of muscle dysfunction on muscle, dyspnea and quality of life in patients with abdominal sepsis ("Abdominal sepsis" group) and patients with extra-abdominal sepsis ("Extra-abdominal" group). Depending on the location of sepsis, this study will enable us to assess and potentially confirm the preferential effect of abdominal sepsis on diaphragm function.
Reducing Empiric VAncomycin Use in Pediatric Suspected Sepsis
SepsisSepsis Mrsa6 moreThe goal of this quasi-experimental interventional study is to determine the effectiveness of a multifaceted stewardship intervention in reducing overall vancomycin use in five tertiary care Pediatric Intensive Care Units (PICU). There are two groups of subjects in this study: PICU clinicians/sepsis stakeholders and patients admitted to one of the participating PICUs during the study period. The intervention will at a minimum include: Implementation of a clinical guideline indicating when vancomycin should and should not be used Unit-level feedback on overall vancomycin use within and across centers Clinician education.
Effect of Kangaroo Care on Heart Rate Variability in Late-onset Neonatal Sepsis
Late-Onset Neonatal SepsisBackground: Neonatal sepsis is the leading cause of mortality in preterm newborns. The autonomic nervous system modulates the response to sepsis through the cholinergic anti-inflammatory reflex. However, premature neonates exhibit immaturity of the autonomic nervous system, which could increase the risk of sepsis. Kangaroo Care (skin-to-skin contact) may promote autonomic nervous system modulation and maturation in preterm newborns with sepsis. The objective of this study is to determine the effect of Kangaroo Care on heart rate variability in preterm newborns with late-onset clinical sepsis. Methods: A cross-over randomized clinical trial will be conducted, including 20 preterm infants with late-onset sepsis. The autonomic nervous system will be assessed using heart rate variability analysis. The study interventions consist of routine care in an incubator and Kangaroo Care. Randomization will be performed using a four-block permuted design for the two intervention sequences AB: Kangaroo Care - incubator care, or BA: incubator care - Kangaroo Care. Heart rate variability will be recorded using a Polar Rs800 monitor and analyzed with Kubios software. Discussion: This study will provide information on the relationship between Kangaroo Care and autonomic nervous system activity in preterm neonates with late-onset sepsis. These data will contribute to the understanding of the cholinergic anti-inflammatory reflex in neonates and the capacity of skin-to-skin contact to modulate autonomic activity in neonatal infection. Thus, the study seeks to provide initial evidence for the use of skin-to-skin contact as a non-pharmacological therapeutic intervention in neonatal sepsis.

SepsisPneumonia2 moreAn adaptive platform trial to compare effectiveness of different care models to prevent readmissions for patients hospitalized with sepsis or lower respiratory tract infection. The primary outcome is number of days spent at home within 90 days after hospital discharge.
Precision Exercise to Improve Outcomes in Sepsis
SepsisThe goal of this interventional clinical research study is to assess the efficacy of a 12-week precision exercise training intervention to improve exercise tolerance in sepsis survivors. The main question it aims to answer is does a 12-week precision exercise training program improve constant load exercise time in sepsis survivors? Participants will: Answer questionnaires related to patient reported outcomes and give a blood sample Perform a constant load exercise test Complete 12-weeks (3 x per week, 36 session in total) of precision exercise training consisting of individualized, nonlinear periodized strength and aerobic exercise training. Researchers will compare the exercise group to an attention control group of sepsis survivors who do not receive exercise training but instead undergo usual care procedures and receive general lifestyle advice 1x per week.
Machine Learning Sepsis Alert Notification Using Clinical Data
SepsisSevere Sepsis1 moreMachine learning is a powerful method to create clinical decision support (CDS) tools, when training labels reflect the desired alert behavior. In our Phase I work for this project, we developed HindSight, an encoding software that was designed to examine discharged patients' electronic health records (EHRs), identify clinicians' sepsis treatment decisions and patient outcomes, and pass those labeled outcomes and treatment decisions to an online algorithm for retraining of our machine-learning-based CDS tool for real-time sepsis alert notification, InSight. HindSight improved the performance of InSight sepsis alerts in retrospective work. In this study, we propose to assess the clinical utility of HindSight by conducting a multicenter prospective randomized controlled trial (RCT) for more accurate sepsis alerts.
Use of Procalcitonin, a Blood Test to Guide Antibiotic Therapy for Sepsis in Adults
SepsisTrial design: Randomised controlled, two-arm, parallel, clinical trial to assess the efficacy and safety of sequential daily procalcitonin assessments to guide de-escalation of empirical antibiotic therapy in adult patients with sepsis. Trial settings Trial site is Chattogram Medical College Hospital (CMCH), Bangladesh. CMCH is tertiary care hospital with undergraduate and postgraduate teaching facilities. This tertiary hospital receives referrals from urban and rural areas of southern Bangladesh and has basic facilities for intensive care and haemodialysis. Trial Participants: Male or female hospitalised patients, 16-65 years of age, with confirmed or suspected sepsis Patients (Total 532) will be 1:1 randomised to either: Intervention arm: daily measurement of serum procalcitonin concentrations to guide de-escalation of antibiotics (Intervention arm: 266), or Control arm: standard of practice to guide de-escalation of antibiotics without procalcitonin assessments (Control arm: 266). Patients will be followed-up until ICU discharge and/or hospital discharge with an additional follow-up at 28 days after discharge.

Effect of the 1-hour Sepsis Bundle on In-hospital Mortality in Patients With Sepsis in the Emergency...
SepsisReducing the mortality and morbidity of sepsis is a worldwide priority for almost 20 years. Since an observational study in the NY state, which reported in-hospital mortality increased, associated with each supplemental hour to complete the sepsis bundle, SSC guidelines have decided in 2018 to recommend a short timeframe of 1-h to complete the sepsis bundle. This new recommendation is vividly debated due to a lack of evidences of its relevance. No trial has ever studied a sepsis intervention when applied as early as Emergency Department ED triage (newly recommended 1-h sepsis bundle consider time zero as time of ED triage). The aim of this trial is to demonstrate that the early implementation at ED triage of the 1-hour bundle by ED physicians improves in-hospital mortality in patients with sepsis, and therefore provides the required robust evidence for the SSC guidance to enhance physicians and stakeholder adherence. This is a superiority, international multicenter, open trial with a stepped wedge randomisation. All centers will recruit adult emergency patients with suspicion of sepsis as defined by a suspicion of infection and suspicion of life threatening organ dysfunction (quick SOFA or SOFA ≥ 2, hypotension or hyperlactatemia). According to the center period, the management of sepsis patients will be based either following the current recommended 1-hour sepsis bundle (intervention group) or at the discretion of the treating ED physician as in current routine practice (control group). There is no intervention that is "added" by the research.
GM-CSF for Reversal of immunopAralysis in pediatriC sEpsis-induced MODS Study
Pediatric Sepsis-induced MODSThis study is an open-label, multi-center, interventional trial in which children with sepsis-induced MODS undergo surveillance immune function testing beginning on Day 2 of MODS. Those children who demonstrate immunoparalysis (TNF-alpha response <200 pg/ml) will receive a 7-day course of GM-CSF at a dose of 125 or 250 mcg/m2/day by either the intravenous (IV) or subcutaneous (SQ) route. The goal of the study is to establish the dose and route of delivery that results in resolution of immunoparalysis (TNF-alpha response >=200 pg/ml) by the morning after the 3rd scheduled dose with persistent resolution of immunoparalysis on the morning after the 7th scheduled dose. Resolution of immunoparalysis in 8 out of the first 10 subjects in a study treatment arm represents a successful dose and route. The goal of this study will be achieved through the following Specific Aims: Specific Aim 1. Establish the immunologic efficacy of GM-CSF administered by the IV and SQ routes in children with immunoparalysis in the setting of sepsis-induced MODS. Specific Aim 2. Estimate the pharmacokinetic parameters by the IV and SQ GM-CSF administered in pediatric sepsis-induced MODS. Specific Aim 3. Demonstrate the feasibility of screening, enrollment, drug delivery, and sample collection for a multi-center immunostimulation trial in children with sepsis-induced MODS.
Early Administration of Vitamin C in Patients With Sepsis or Septic Shock in Emergency Departments...
SepsisSeptic Shock2 moreIn this clinical trial the effect of early administration of Vitamin C is investigated in patients admitted at the emergency department with sepsis or septic shock. When a patient has sepsis, his/her body is causing damage to its own tissues and organs as result of an infection. This can lead to septic shock. The patient has a low blood pressure, his/her organs stop working and the patient may even die. The aim of this trial is to investigate the efficiency of Vitamin C in sepsis and septic shock. Vitamin C is a vitamin present in various foods and has been approved as dietary supplement by the Belgian authorities. Over the years it has been proven that Vitamin C is very safe. In addition, several studies have shown that Vitamin C can also have a protective effect. It can reduce organ damage and increase survival rates. Although several studies suggest that Vitamin C can help fight sepsis, it is not yet used in practice. This Belgian trial, in which several hospitals participate, hopes to provide a clear answer to the question: "Should Vitamin C be administered to patients admitted in an emergency department with sepsis or septic shock?"
