the study aims to examine the validity of combined end-expiratory and end-inspiratory occlusion test and tidal volume challenge test for prediction of fluid responsiveness in immediate post-cardiac surgery patients
During cardiorenal syndrome type 1 (CRS1) vascular congestion is the major contributor to worsening renal function, but promoting decongestion with routine clinical evaluation is ineffective in some patients. The venous evaluation by ultrasound (VExUS) may optimize its management when evaluating for improvement in kidney function and other metrics related to decongestion.
Fluid overload is a common feature of diseases such as heart failure and kidney injury, which can lead to pulmonary edema or even death if not treated in time. In order to rapidly relieve fluid overload in patients, a wearable filtrating artificial kidney device was developed. The purpose of this study is to evaluation of the precision, security, and operability of wearable filtrating artificial kidney device for on-site medical rescue.
The aim of this feasibility study is to determine whether an alert embedded within the electronic health record (EHR) causes clinicians to enrol patients into a randomised controlled trial (RCT) comparing oral fluid restriction versus no restriction in patients admitted to hospital with fluid overload. One of the main causes of fluid overload is heart failure where there is a lack of strong evidence to support the effectiveness of oral fluid restriction in the acute setting. This causes significant variation in clinical practice where decisions on whether or not to impose a restriction in oral fluid intake is based on the preference of the treating clinician rather than robust evidence from research. THIRST Alert is a pragmatic randomised controlled trial (RCT), embedded in the EHR, which seeks to determine whether a computerised alert for the clinical team can change clinician behaviour during routine NHS care at University College London Hospitals NHS Foundation Trust (UCLH). Patients with suspected fluid overload will be identified based on the prescription of intravenous furosemide, a medication used to stimulate diuresis (increased urine output) to remove excess fluid. A repeat prescription of intravenous furosemide within the first 48 hours of an unplanned admission will trigger the alert. A clinician from the treating team will then be asked to consider enrolling the patient into the RCT if they judge that oral fluid restriction might be beneficial but they have uncertainty about this (clinical equipoise). Enrolled patients will be randomised to either oral fluid restriction of 1 litre per day or no fluid restriction. This will then be actioned through documenting as part of the clinical plan in the patients record and then communicated to the patient and the rest of the clinical team, including nursing staff. The study will record the number of patients recruited into the trial and the effect of the alert on enrolled patients' subsequent oral fluid intake. There are no additional tests or follow up for patients and the trial finishes on discharge from the study site. All trial outcomes will use data collected from routine care and the study is supported by the UCLH Biomedical Research Centre, funded by NIHR.
In Intensive Care Unit (ICU) patients with acute kidney injury (AKI) and treated with renal replacement therapy (RRT) often present a fluid overload which is associated with morbidity (mechanical ventilation duration increase, kidney recovery decrease) and mortality. Patients' prognostic could be improved by correcting the fluid overload with net ultrafiltration (UFnet) however it may lead to harmful iatrogenic hypovolemia responsible of deleterious ischemic lesions. In usual practice, UF net prescription are variable and there are different international recommendations. Some observational studies suggest that using a UFnet between 1 et 1.75 mL/kg/h in fluid overloaded patient decrease mortality. Fluid overload increases morbidity and mortality, particularly in RRT. Studies without RRT argue for an efficacy of management by decreasing the fluid overload .Cohort studies suggest to use a moderate UFnet instead of a low UFnet. Some data from studies on early versus late RRT that relate the fluid balance or correct the fluid overload during the early strategy argue for a beneficial effect of an early deresuscitation strategy Consequently, the impact of a moderate UFnet (to decrease the fluid overload) compared to a low UFnet (to stabilize the fluid overload) in a randomized interventional study could be assessed. The study hypothesis is that : an early fluid overload deresuscitation protocol with a high UFnet (2 ml/kg/h) targeting both the negativation of cumulated fluid balance to reach a dry weight and the maintenance of tissue perfusion. Compared to fluid overload deresuscitation protocol with a low UFnet (between 0 and 1 ml/kg/h) to reach a stabilization of cumulated fluid balance without monitoring the tissue perfusion. could improve overall, renal, hemodynamic and respiratory prognosis in fluid overloaded patients with renal replacement therapy in ICU
To assess the discriminative properties of pleural fluid (PF) N-terminal-proB-type-natriuretic-peptide (NTproBNP) levels in identifying heart failure (HF)-associated pleural effusions (PE).
Acute microcirculatory perfusion disturbances is common in critical illness and associated with increased morbidity and mortality. Recent findings by our group showed that microcirculatory perfusion is disturbed during cardiac surgery with cardiopulmonary bypass (CPB) and remain disturbed up to 72 (seventy two) hours after surgery. A cardiopulmonary bypass is a machine which takes over heart and lung function, during the procedure. The disturbed microcirculation is associated with organ dysfunction induced by cardiac surgery using CPB, which is frequently seen (up to forty two percent, 42%) and results in a six-fold increase in mortality rate. The underlying cause of disturbed microcirculation is a higher endothelial permeability and vascular leakage and are a consequence of systemic inflammation, hemodilution (dilution of blood), hypothermia and hemolysis (breakdown of red blood cells). To gain the knowledge regarding disturbed microcirculation the investigators previously showed that hemodilution attributes to this disturbed perfusion. Hemodilution lowers colloid oncotic pressure (COP). Also, COP is affected by free hemoglobin, which increases with hemolysis and attributes to a disturbed microcirculation following CPB. This is interesting, as to the best of our knowledge, the effect of minimizing hemodilution and hemolysis during cardiac surgery on the microcirculatory perfusion has never been investigated, but could be the key factor in reducing organ dysfunction.

Researchers from the University of Michigan and Northwestern University are studying people's experiences with swelling caused by Nephrotic Syndrome. Interviews with patients (child and adult) and parents of young children will be conducted. The information collected from the interviews will be used to develop a survey to use when testing new medications for Nephrotic Syndrome. Please consider participating in a 1-hour long interview with the Prepare-NS research study to discuss children and adults experiences with swelling.
