Active clinical trials for "Critical Illness"

The purpose of this study is to pilot data for a systematic molecular characterization of pathophysiologic perturbations incurred by snake envenomation and compare this to other inflammatory physiologic states such as trauma and sepsis. This sub-study will analyze samples of participants enrolled under the parent study "Surgical Critical Care Initiative Tissue and Data Acquisition Protocol".

In critically ill patients, the small bowel permeability is increased, leading to bacterial translocation, and systemic inflammatory response syndrome. Plasma citrulline is a validated biomarker of functional enterocyte mass. Lipopolysaccharide (LPS) is a part of Gram negative bacteria, and plasma LPS concentration is a biomarker of bacterial translocation. The link between plasma citrulline and LPS in the critically ill is unknown. Investigators hypothesize that patients presenting with low plasma citrulline concentration, with presumed altered small bowel function, would have an increased phenomenon of bacterial translocation, and increased plasma LPS concentration. Investigators aimed to evaluate the link between plasma citrulline and LPS concentrations in critically ill patients at the time of ICU admission.

Critically ill patients with body mass index (BMI) inferior to 20 kg/m2 have worse outcomes compared to normal and overweight patients. The impact nutrition therapy in this population is not yet stablished. There is a concern that too low caloric intake might worse their malnutrition; on the other hand, overfeeding is always a risk with serious consequences. The hypothesis of this study is that nutritional support, especially caloric and protein intake, can influence the outcome of underweight critically ill patients.

The objective of this study is to describe the pharmacokinetics of standard doses of caspofungin in critically ill patients.

Measure the lung strain in different tidal volume in ADRS patients to find the relationship between tidal volume and lung strain and find the most suitable tidal volume for each patient.

In critical illness, patients are highly stressed and should have elevated cortisol (stress hormone) secretion to adapt to stress. Dysfunction of this system is referred to as critical illness-related corticosteroid insufficiency. Free cortisol (unbound form) which is mainly responsible for its physiologic function is difficult to measure. We hypothesized that the salivary cortisol, which can be obtained by noninvasive methods, can more accurately evaluate adrenal function of critically ill patients.

The purpose of this study is to determine how often ventilator associated pneumonia happens in the current intensive care units, and how types of endotracheal tube affect its occurrence.

This is a prospective observational single-center study in which the association of Protein-Energy Adequacy and 28-Days of Mortality among critically ill patients with Acute Kidney Injury, AKI will be investigated. The association of Protein-Energy adequacy with a length of ICU and hospital stay, total ventilator, and inotropic drug days among critically ill patients with AKI also will be investigated.

In this prospective longitudinal cohort the investigators reported the clinical, and biological characteristics of all critically ill patients admitted in the pediatric intensive care unit (PICU) of Bicêtre Hospital during the 2019 coronavirus disease (COVID-19) pandemics. Patients were older than 37 weeks of gestational age. No upper limit was set as the unit was transiently converted into a pediatric "adult COVID-19" intensive care unit.

Survivors of critical illness may suffer from persistent physical, cognitive and mental impairments, such as muscle weakness, dysfunction in the memory and executive domains, post-traumatic stress disorders, depression, and anxiety. This syndrome is referred to as Post Intensive Care Syndrome (PICS). This study aims to assess the frequency of impairments, their evolution over time, and to understand the pathogenetic mechanisms and the association between long-term sequelae and acute care events.
