Filter by:This study is intended to clinically verify Monocyte Distribution Width (MDW) parameter of DxH 900 Hematology Analyzer for use in early detection and risk assessment of sepsis, severe sepsis, and septic shock in critically ill patients in Emergency Department (ED). This study is also aimed to provide study supporting data for the product to be marketed in China.
The object of the scientific research is the characterization of the pharmacokinetic profile and the investigation of factors of pharmacokinetic variability of amikacin and vacnomycin in critically ill patients with a diagnosis of sepsis-like condition (SIRS), hospital-acquired sepsis and/or septic shock and who are on extracorporeal therapy with Cytosorb® and Oxiris® adsorbents.
The purpose of this study is to determine whether additional investigations used in other parts of healthcare can be used in the Emergency Department to identify critically ill patients quicker than usual care.
This is a single-center retrospective study conducted at Mercy hospital, aiming to investigate the correlation between changes in hemoglobin (Hb) levels and the volume of vascular refill administered during the first 48 hours.
Sepsis is a serious health problem with a very high mortality in the ICU. The most important treatment for sepsis is the fastest possible antibiotic therapy. The identification of the pathogen responsible for sepsis is essential to propose an appropriate antibiotic treatment. However, the diagnosis of bacteremia by blood culture requires an average delay of 48 to 72 hours. The new test proposed by OCEAN Dx makes it possible to identify a bacteremia in a few hours. The main objective of the study is to evaluate the performance of the rapid identification test for bacteremia proposed by OCEAN Dx compared to a classic diagnostic strategy using blood cultures.
The goal of this prospective observational study is to develop and utilize an Artificial Intelligence (AI) model for the prediction of postoperative sepsis in patients undergoing abdominal surgery. The main questions it aims to answer are: 1. Can a remote AI-driven monitoring system accurately predict sepsis risk in postoperative patients? 2. How effectively can this system integrate and analyze multimodal data for early sepsis detection in the surgical ward? Participants are equipped with non-invasive PPG-based wearable devices to continuously monitor vital signs and collect high-quality clinical data. This data, along with demographic and laboratory information from the Electronic Health Record (EHR) of the hospital, are used for AI model development and validation.
Acute kidney injury (AKI) is a common complication among patient admitted in the hospital worldwide, with estimates of prevalence ranging from less than 1% to 66%.1, 2 In critically ill patients approximately 49% were acute kidney injury network (AKIN) stage 3 which required intensive care unit (ICU) admission, kidney replacement therapy (KRT), and is associated with higher mortality rate.3 Sepsis-associated acute kidney injury (S-AKI) is a frequent complication in critically ill patient and is associated with high morbidity and mortality. S-AKI is defined as AKI in presence of sepsis without other significant contributing factors or simultaneous presence of both Sepsis-3 definition and Kidney Disease Improving Global Outcomes (KDIGO) criteria for AKI. 4, 5 Multicentre studies show that 30-60% of critically ill patient having AKI, and approximately 10-15% require KRT.6 Both Online-hemodiafiltration (OL-HDF) which is convection-based hemodiafiltration and conventional intermittent hemodialysis (IHD) which is diffusion-based hemodialysis are modalities of KRT that can be used to treat AKI in sepsis.7 Conventional intermittent hemodialysis (IHD) involves the removal of waste products and excess fluids from the blood by using a semipermeable membrane that acts as an artificial kidney. However, IHD has limitations in removing certain larger solutes, such as cytokines, which are involved in the inflammatory response associated with sepsis. In contrast, OL-HDF is a more advanced form of hemodialysis (HD) that combines convective clearance with diffusive clearance, resulting in more efficient removal of larger solutes.8 Several studies have suggested that OL-HDF may have advantages over conventional HD in the management of sepsis-associated AKI.9 Some studies found that OL-HDF was associated with improved patient survival and lower incidence of dialysis dependence compared to conventional IHD. Additionally, some studies have suggested that OL-HDF may have anti-inflammatory effects, which could be beneficial in sepsis.9-11 Some observational studies have shown that OL-HDF provide benefit over IHD including, a reduction in the length of ICU stay and a decrease in inflammatory surrogate markers. However, the effect of OL-HDF in improving survival has not yet been established. 1, 7, 9 Some studies have shown that sustained low-efficiency dialysis (SLED) may has advantage in hospital survival in over the continuous veno-venous hemofiltration (CVVH) modality.12 While there are several extracorporeal treatment modalities for AKI in critically ill patients but no randomized study has yet demonstrated a survival benefit over another. A prospective and comparative study between IHD and OL-HDF groups showed no significant difference in mortality between the groups. However, a significant benefit in terms of a reduced length of ICU stays and vasopressor free day was found in the OL-HDF group.13 The past studies show that CRP and IL-6 levels increase in patients treated with IHD and remain stable in patients treated with OL-HDF, with a statistically significant difference. 14 In AKI patient, our aim is to remove small molecules such as uremic toxin or metabolic abnormalities. In chronic kidney disease, the benefit of high flux dialyser or OL-HDF to remove middle to large molecule such as ß2-microglobulin and others chronic inflammation molecules and cytokines through a combination of diffusion-based and convection-based techniques are well-known. These cytokines including C-reactive protein (CRP), interleukin 6 (IL-6), interleukin 10 (IL-10), procalcitonin (PCT), which are commonly elevated in AKI patient, have been shown to be significantly reduced by using hemodiafiltration techniques. 9, 15 However, the benefits of removing middle molecule and inflammatory makers in the acute setting such as AKI in critically ill patient remain controversial.11, 16, 17 Therefore, this study aims to verify the benefit of convection-based treatment in reducing inflammatory molecule such as CRP over diffusion-based treatment in both critically-ill and standard AKI patients. However, it is important to note that OL-HDF requires specialized equipment and may be more complex to administer compared to conventional IHD. Additionally, it is generally more expensive. Therefore, the choice of KRT modality in sepsis-associated AKI should be based on careful consideration of the individual patient's clinical status and available resources.7 It is important to note that every patient's condition is unique and requires individualized treatment, so the specific choice of KRT modality should be made in consultation with a healthcare professional.
Sepsis is one of the main causes of mortality and morbidity in an ICU setting, while the responsible microorganisms most frequently isolated are multidrug-resistant gram-negative bacteria. Aminoglycoseides (AG) seem to be particularly effective in dealing with these microbes, however their potential toxicity, especially nephrotoxicity, often makes them an unsuitable treatment option. This becomes particularly evident in patients with already impaired renal function, a common occurrence in septic patients requiring ICU treatment. AG are bacteriocidal antibiotics the efficiency of which depends on the maximum concentration in patients' serum (Cpeak). Pathophysiological changes in critically ill patients, result in significant distribution of the drug extravascullary resulting in a decreased concentration of the biologically active component. On the other hand, impaired renal clearance results in high serum drug levels (C trough) making the desired once-daily administration not always achieved. The purpose of this study is to test the hypothesis of successful clearance of AG after achieving satisfactory serum levels and therefore their maximum effect minimizing potential toxicity, by using continuous veno-venous haemodiafiltration in patients with sepsis or septic shock and impaired renal function. This way, the aforementioned antibiotics could become a more frequent and potentially earlier choice for physicians in the treatment of sepsis and septic shock patients from multidrug-resistant microbes.
Sepsis is a disruption of homeostasis in the human body in response to bloodstream infection and is associated with a high risk of mortality. Worldwide, sepsis is affecting approximately 30 million people and resulting in six million deaths. Blood culture is a specific blood sample used to identifying microbial agent (bacterium or yeast) and determine the sensitivity of these microorganisms to antibiotics and antifungals. Any delay in identifying the microorganism and/or determining the AST (antibiotic susceptibility testing) has a direct impact on the administration of appropriate antibiotic treatment and, consequently, on mortality of the patient. The faster the diagnosis, the faster the antibiotic treatment will be adapted, the higher the survival rate/probability of patients, and the lower the ecological impact. In routine, clinical microbiology laboratories currently use 2 automatized techniques: MALDI-TOF MS® for microorganisms identification and VITEK2® method for AST determination. Based on a proteomic approach, the IDBIORIV method is a rapid method (90 minutes) in comparison of current methods (24/48 hours) able to identifying a large panel of 113 pathogens and determine the antibiotic resistance profile of 49 species for 4 classes of antibiotics (Beta-lactams, Aminosides, Glycopeptides, Colistin). The main objective of this study is to evaluate the performance of the IDBIORIV method in pathogen identification and antibiotic susceptibility testing in comparison with current methods of analysis of positive blood cultures used at the microbiology laboratory of the Hospices Civils de Lyon, in a real clinical situation, over a 2-year period.
29.3% of bacteremias in intensive care units (ICU) are linked to vascular devices, with a significant proportion related to central venous catheters, and an influence on both morbility and mortality. It is now accepted that microbiological biofilm plays a key role on both bacterial and fungal development on inner surface of vascular devices but there is yet a lack of clinical relevant data documenting a causal relation between biofilm formation and bacteremias. We assume that a more precise characterization of central venous catheter-deposited biofilm could help us better understand invasive medical device-related healthcare infections in critically ill patients.
