Filter by:Objective: This study aims to use machine learning methods to establish an optimal model for predicting serum vancomycin trough concentrations in critically ill patients. Methods: This is a single-center, retrospective study. Data on serum vancomycin concentration in the Critical Care Database of Peking Union Medical College Hospital were screened and extracted to construct a prediction model using machine learning methods. The MIMIC-IV (Medical Information Mart for Intensive Care) database will be further used for external verification of the constructed model. The study has been approved by the Medical Ethics Committee of Peking Union Medical College Hospital (K24C1161).
The goal of this clinical trial is to investigate the effects of nutrition therapy guided by indirect calorimetry and nitrogen balance among critically ill patients with acute kidney injury. The main question it aims to answer whether nutrition therapy guided by indirect calorimetry and nitrogen balance could improve 28 days mortality among critically ill patients with acute kidney injury or not. type of study: clinical trial Participants will be provided enteral or parenteral nutrition after randomization(48-72 days after admissions) with total energy guided by indirect calorimetry measurements and total protein by nitrogen balance with maximum of 1.3 gram per kilogram per day for total of 14 days If there is a comparison group: Researchers will compare with the control groups (nutrition therapy provided by physician using clinical equation of choice or judgements to see if participants were provided with these interventions, their 28 days mortalities would be better
Rationale: A significant proportion of patients admitted to the Intensive Care Unit (ICU) is unable to fully recover, even when the initial cause of their illness has been treated. Inadequate dietary intake prior to admission and during the recovery phase may leave patients in a frail physical state, limiting rehabilitation potential. Commonly used methods to assess nutritional intake and nutritional status are highly impacted by various disease-related confounders and reporting bias. We hypothesise that a combined assessment of biomarkers in plasma and urine may provide a more accurate overview of nutritional status at ICU-admission. Objective: Main: Assess nutrition-related biomarkers in plasma and urine samples at ICU admission Secondary: Identify the number of micronutrient deficiencies at ICU admission Compare biomarker profile and dietary intake of short and long-stay ICU patients at baseline Compare subjective dietary intake, nutritional status and muscle thickness between patients with and without micronutrient deficiencies at baseline Study design: Observational study Study population: Adult patients admitted to the ICU. Two groups will be recruited: patients with a short length of stay (<48 hours) and patients with a longer length of stay (≥48 hours). Main study parameters: Biomarker status in blood and urine at ICU admission. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: In addition to standard care ICU treatment, the following measurements will be performed: - Within 24 hours after admission blood and urine samples will be collected from existing venous line and urinary catheter - Within 72 hours an ultrasound measurement of the upper leg will be performed. - During ICU stay, when the patient is capable to do so, they will be asked to complete a retrospective dietary intake assessment. The risks and negative effects of these tests are limited. However, this study asks for a time investment and physical and mental effort of the patients.
Overarching hypothesis In critically ill adults enteral feeding in a diurnal intermittent pattern improves patient centred outcomes. Research questions for this study Are the same derangements in metabolic and hormonal function observed in healthy volunteers when fed continuously via a nasogastric tube observed in critically ill patients and can those derangements be mitigated by intermittent diurnal feeding? Aim of this study Assess the effect of an enteral nutrition regimen mimicking the usual diurnal meal pattern on hormonal profile and metabolism in critically ill adults. This will generate novel and important proof of concept data and support progression to a clinical trial integrating investigation of physiological responses and patient centred outcomes. Objectives of this study Laboratory: Characterise patterns of hormone, lipid and metabolite response to intermittent diurnal feeding in critically ill adults. Clinical: assess feasibility, tolerability (vomiting and gastric residual volume) and efficacy (calorie delivery) of intermittent diurnal feeding in critically ill adults.
Critically ill patients are known to develop serious nutritional deterioration during the course of their disease. They develop, from the beginning, a multifactorial protein malnutrition that relates to a poor clinical course and the development of weakness. Due to the increased protein catabolism in this type of patient, there is a rapid degradation of muscle mass and loss of functional proteins, and therefore nutritional support is mandatory. Indeed, achieving a high protein intake may promote a better evolution of the critically ill patient, i.e., maintenance of muscle protein, less deterioration of muscle strength, lower Intensive care unit-acquired weakness (ICUAW), lower mortality, decrease in the number of infections, decrease in days on mechanical ventilation, and days of hospital stay and in ICU. The goal of this clinical trial is to compare the appearance and degree of ICUAW in critically ill patients receiving invasive mechanical ventilation treated with two different doses of protein (1.5 g/kg/day vs.1.0 g/kg/day).
Critical illness-related corticosteroid insufficiency (CIRCI), a term coined since 2008 by Society of Critical Care Medicine (SCCM), and is characterized by inflammation resulting from inadequate intracellular glucocorticoid-mediated anti-inflammatory activity leading to increased morbidity and mortality in Intensive Care Unit (ICU) patients.1 Severe Sepsis with shock is a common reason for admission to ICU/hospital and may require ionotropic support.2 The current guidelines from SCCM in 2017 suggest using either random cortisol of < 10 ug/dL (<276 nmol/L) or change in cortisol at 60 min after cosyntropin (250 µg) administration from baseline cortisol of <9 µg/dl (<248 nmol/L) to assess of presence of CRCI and recommend use of hydrocortisone in these patients.3 There have been studies done to look at baseline cortisol in patient with severe pneumonia requiring ICU and they have found cortisol level of < 15 ug/dl (<414 nmol/L) can predict CIRCI.4 However, there is no study on assessment of baseline random cortisol levels in patients with septic shock in our local population. The current guidance from Surviving Sepsis campaign suggests a more clinical approach of adding IV corticosteroids only if there is ongoing requirement for vasopressors, which is a new change in contrast to 2016 guidelines.5 This study aims to look the available mean baseline cortisol in these patients to create a reference data for local population.
This is a Pilot study designed to set up for an randomized clinical trial (RCT) comparing the SeND Home pathway to a standard of care nutrition delivery in critically ill older adult trauma patients. Subjects will be randomized 3:1 to either SeND Home precision nutrition pathway or control arm. Subjects randomized to the SeND Home arm will receive oral nutrition supplements (ONS) up to 3 times per day while in the hospital and for 4 weeks after discharge. Subjects in the standard of care arm will receive normal nutrition recommendations from their clinical providers. Participants in both groups will undergo non-invasive tests that measure how much energy (calories) they are using, body composition, and muscle mass.

Introduction: Venous thrombosis (VTE), including both deep vein thrombosis (DVT) and pulmonary embolism (PE) remains a frequent complication in patients admitted to the Intensive Care Unit (ICU). Multiple prediction models for estimating the risk of VTE have been developed. However, many models have not been externally validated. The aim of this study is to perform a comprehensive external validation of pre-existing prediction models for predicting the risk of in-hospital VTE in critically ill patients. In case current risk assessment models fail, the investigators aim to additionally develop and internally validate a new risk prediction model. Methods: During the first phase of the study the investigators will perform external validation of existing prediction models. The performance, discrimination, calibration and clinical usefulness of the models will be evaluated. In the second phase of the study, in case performance of current risk assessment models is deemed insufficient for clinical application, the investigators will develop a model for predicting the risk of in-hospital VTE in critically ill patients. A multivariable prediction model will be constructed using a combination of predefined candidate predictors. This model will be internally validated and performance will be compared with performance of existing VTE risk prediction models. Dissemination: This protocol will be published online. This study will be reported according to the Transparent reporting of a multivariable prediction model for individual prognosis or diagnosis (TRIPOD) statement and this study will be submitted to a peer-reviewed journal for publication.
