18 Clinical Trials for Various Conditions
The goal of this study is to develop a non-invasive test to diagnose intensive care unit (ICU) acquired weakness that can be administered to both responsive and non-responsive patients. Study participation will involve the measurement of muscle fatigue during a single 30 minute session. Skeletal muscle will be stimulated with an FDA approved clinical electrical stimulator and accelerations will be passively recorded with an accelerometer.
ICU-acquired weakness represents a common and often devastating disease process which affects greater than 50% of critically ill patients. This pathogenesis of this acquired disease is multifactorial and results in variable severity, ranging from mild, transient to severe, permanent dysfunction of peripheral nerves in additional to muscle. In affected patients, weakness may persist for months to years after the acute phase of their illness, and has been implicated as a major contributor to decreased functional status and quality of life. Muscle ultrasound has been validated for assessment of muscle size as well as diagnosis of myopathic and neuropathic changes in patients with other known neuromuscular diseases. The use of muscle ultrasound or other imaging modalities for diagnosis or monitoring of ICU-acquired weakness has not been studied, although a single study using muscle ultrasound has shown significant change in muscle size in ICU patients receiving high dose corticosteroids and a prolonged course of paralytic agents. The investigators plan to use multiple modalities to examine skeletal muscle catabolism, function, and structure in patients during critical illness and recovery. The investigators will combine physical exam, hand grip dynamometry, electrophysiologic studies, serum biomarkers, muscle biopsies, and muscle ultrasound to assess a group of critically ill patients during their hospital stay. The investigators will obtain additional data, including neuropsychiatric assessments, severity of illness scores, administration of potentially harmful medications, and pertinent daily laboratory data. This study will last approximately 12 months.
To better understand ICU-acquired weakness in patients requiring mechanical ventilation in the Intensive Care Unit.
Every patient admitted to the Intensive Care Unit (ICU) is at risk of developing "Intensive Care Unit Acquired Weakness" (ICUAW). ICUAW is associated with increased rate of mortality, prolonged duration of mechanical ventilation, ICU and hospital stay, rehabilitation time, and reduced quality of life. Currently, there is no effective treatment for ICUAW. Health Discovery Labs is conducting a research study to evaluate the safety of using an innovative experimental medical device in ICU settings that could mitigate ICUAW. This study is meant to demonstrate whether this new device interferes with standard ICU monitors.
The overarching goal of the proposed study is to determine the trajectories of physical recovery and cellular markers involved with the underlying failure to recover muscle after critical illness, while exploring which characteristics are associated with sustained physical disability. This proposal will examine muscle pathophysiology carefully aligned with physical function outcomes in order to longitudinally assess the recovery, or failed recovery, of muscle function in participants after critical illness: 1. to examine the recovery of muscle and physical function in ICU survivors through longitudinal assessments 2. to investigate the underlying cellular markers and mechanisms of muscle recovery in ICU survivors 3. to determine which cellular markers contribute to physical disability in ICU survivors up to 1 year after hospital admission
The purpose of this study is to evaluate the efficacy, safety, and pharmacokinetics (PK) of FDY-5301 compared to placebo in major trauma ICU patients at risk of intensive care unit acquired weakness (ICUAW)
Critically ill patients in the intensive care unit are known to lose muscle mass and function at a rapid rate. Currently, there is a global recognition and shift in the ICU culture to reduce sedation and encourage exercise and mobilization early during the ICU stay. Functional stimulation assisted supine cycling can be applied to patients in the bed and does not require patient participation. This study seeks to evaluate the effect of conventional exercise and early mobilization in combination with functional stimulation assisted supine cycling applied early during the ICU on muscle mass, strength, and physical function, as well as patient-reported disability as compared to conventional exercise and early mobilization alone.
The overarching goal of this study is to support the "real world" assessment of strategies used to foster adoption of several highly efficacious evidence-based practices in healthcare systems that provide care to critically ill adults with known health disparities. Investigators will specifically evaluate two discrete strategies grounded in behavioral economic and implementation science theory (i.e., real-time audit and feedback and registered nurse implementation facilitation) to increase adoption of the ABCDEF bundle in critically ill adults.
Older ICU survivors with ICU acquired weakness (ICUAW) are malnourished, sarcopenic, and functionally debilitated as a consequence of the high burden of comorbidities common in the elderly. To address the sequalae of critical illnesses, the investigators will perform a trial incorporating an intervention that combines mobility-based physical rehabilitation (MRP), high protein supplementation (HPRO), and neuromuscular electric stimulation (NMES). The investigators will then assess both clinical and functional outcomes and determine the relationship of disability with systemic inflammation.
Multicenter, prospective, randomized controlled trial providing mobile health supported physical rehabilitation to 120 patients who have been critically ill with COVID-19 and who complete at least one exercise session.
Background \& Significance. Children with congenital heart disease (CHD) have experienced improved postoperative survival shifting the focus away from minimizing mortality to curtailing morbidities. Critical illness following cardiac surgery induces catabolism which may impact functional status. Catabolism, a state in which protein breakdown exceeds protein synthesis, can lead to lean body mass (LBM) breakdown. LBM loss has been associated with poor clinical outcomes. Muscle ultrasound (mUS) has been utilized to measure LBM changes and the functional status score (FSS) was developed to assess functional status changes in children following hospitalization. The ability to identify LBM loss acutely and its association with FSS changes may lead to earlier interventions to preserve LBM and aid in outcome prediction. Specific Aims \& Hypotheses. Specific Aim 1 is to identify the percent change in LBM by mUS during the first postoperative week in children following complex cardiac surgery. Specific Aim 2 is to evaluate the relationship between percent change in LBM during the first postoperative week and the FSS at discharge and 6 and 12-month follow-up in children with CHD following complex cardiac surgery. The investigators hypothesize children with CHD following complex cardiac surgery will experience a decline in LBM and that there is a direct relationship between the change in LBM and postoperative FSS follow-up. Study Design \& Methods. The investigators are conducting a single-center, prospective, observational cohort study. Consecutive children (\> 3 months and \< 18 years of age) with CHD undergoing biventricular conversion will be enrolled. Patients will undergo a baseline mUS and FSS at the time of the index operation. Interval mUS will be obtained on the third and seventh postoperative day. Discharge mUS and FSS will be obtained and a remote FSS will be requested by the family at 6 and 12-months postoperatively. Demographics, pertinent laboratory, concomitant medications, nutrition and ultrasound variables will be collected. Outcomes. The primary outcomes will be change in LBM during the first postoperative week and change in FSS at 6 and 12-month follow-up in children following complex cardiac surgery. Change in LBM will be defined as a percent change in cross-sectional area of the quadriceps muscle layer thickness (QMLT). Change in FSS will be significant if the score drops 3 points or more from baseline at postoperative follow-up.
Critically-ill patients with liver disease are at high risk of developing sarcopenia and intensive care unit (ICU)-acquired weakness, which are associated with mortality and other poor outcomes. Early physical rehabilitation has shown benefit in ICU settings, but has not been studied in ICU patients with acute and chronic liver failure. Cycle ergometry, or stationary cycling in passive and active modes, may be especially beneficial to such patients due to their high prevalence of severe physical deconditioning and variable mentation. The aim of this study is to examine the feasibility, safety, and benefit of cycle ergometry over standard physical and occupational therapy (PT/OT) in critically-ill patients who have acute or chronic liver disease.
The investigators propose to conduct a randomized, control trial of β-hydroxy-β-methylbutyrate (HMB) supplementation in elderly patients (≥65 years of age) with acute respiratory failure, who are identified at high risk for malnutrition by ICU-specific nutritional risk scores. Patients will receive either 3g of HMB daily, or control, daily until day 28 following randomization (even if discharged).The investigators will measure functional outcomes using standard, validated measures prior and after discharge.
Elderly patients who experience a prolonged ICU stay are at high risk for developing post intensive care unit syndrome (PICS), a serious medical condition manifested by loss of muscle mass, weakness, malnutrition and neurocognitive decline. PICS often leads to chronic disability, prolonged mechanical ventilation and the need for costly extended stays in long term care facilities (LTCs). The investigators' preliminary study shows attempts at rehabilitating patients who have already developed PICS are minimally effective, resulting in only modest improvements in functionality. This project will determine the effects of mobility-based physical rehabilitation (MPR) combined with neuromuscular electric stimulation (NMES) and high protein supplementation (HPRO) early in a patients ICU stay on preventing PICS related musculoskeletal and functional deficits, and improving clinical outcomes.
Patients who are admitted to the intensive care unit and require mechanical ventilation frequently develop profound respiratory and limb muscle weakness. Studies show that the development of weakness during the ICU stay results in poor outcomes. Currently there are no treatments for this muscle weakness, but it has been suggested that this weakness might improve with physical therapy. Electrical stimulation is a method to provide direct stimulation to the muscles potentially enhancing function and improving strength. The purpose of this study is to test the hypothesis that neuromuscular electrical stimulation of the quadriceps muscle will improve muscle strength in patients who are critically ill on mechanical ventilation.
To study all ICU patients with an independent baseline functional status , who experience a critical illness requiring intubation and mechanical ventilation evaluating long-term cognitive and executive function and long term cost effectiveness in survivors who required mechanical ventilation.
To study all ICU patients with an independent baseline functional status, who experience a critical illness requiring intubation and mechanical ventilation, evaluating the role of protocol-directed, early physical and occupational therapy on the incidence of critical illness associated functional debilitation. Our goal is to hasten the recovery of independent physical functioning as well as to reduce ICU delirium in the group of patients who begin this intervention from the earliest hours of ventilator dependence.
This study seeks to define the morbidity of critical care polyneuropathy and to confirm that this diagnosis is, in fact, independently associated with increased mortality. Secondary information regarding the reasons for ICU readmission in patients with weakness may help in formulating cogent discharge strategies for these patients. Measurement of weakness using handgrip strength may provide a useful surrogate marker for weakness that may be more easily and uniformly applied. Primary hypothesis: * The development of ICU-associated weakness is independently associated with excess attributable mortality. Secondary hypothesis: * The development of ICU-associated weakness is associated with an increased need for ICU readmission. * Readmission to the ICU will be a result of the development of recurrent respiratory failure or insufficiency * Handgrip strength testing will detect ICU-associated weakness with an equivalent sensitivity as the comprehensive bedside muscle strength exam.
