Filter by:Prone positioning is a well studied and validated treatment for severe acute respiratory distress syndrome (ARDS), however there are no randomized studies on the use of prone positioning in the non-intubated patient. It is unknown if this intervention would be helpful in preventing further respiratory deterioration in terms of increasing supplemental oxygen requirements, endotracheal intubation, and ICU admission. The Awake Prone Position for Early hypoxemia in COVID-19 (APPEX-19) Study is a pragmatic adaptive randomized controlled unblinded trial. APPEX-19 randomizes non-ICU patients with COVID-19 or who are under evaluation for COVID-19 to lie in a prone position (i.e, with their stomach and chest facing down) or to usual care.
The main purpose of this study will be to evaluate the prognostic value at 3 months of life of brain perfusion MRI determined by Arterial Spin Labeling technique in the first week of life of term newborns with hypoxic-ischemic encephalopathy requiring management in neonatal intensive care unit.
To test the accuracy of a non-invasive blood oxygen saturation monitor which is placed on a subject with profound hypoxia.
Due to age-related effects, the bone and cardiovascular health are damaged. Physical exercise and in particular the strength training has been proposed as a fundamental tool to these pathologies, especially in the elderly. On the other hand, the use of normobaric hypoxia combined with exercise could have a beneficial synergistic effect on disease prevention and the quality of life of the elderly. Therefore, the general objective of this project is to analyze the effects of different methods of strength training combined with conditions of normobaric hypoxia on the bone and cardiovascular health of the elderly. This general objective is specified in the following specific objectives: - To analyze the effects of circuit training with elastic bands on bone mineral density and bone remodelling markers of elderly, under normoxic and normobaric hypoxic conditions. - To analyze the effects of circuit training with elastic bands on biochemical parameters, inflammatory, endothelial and clinical markers just like cardiovascular risk level of elderly, under normoxic and normobaric hypoxic conditions. - To analyze the effects of circuit training with elastic bands on body composition and functional capacity of elderly, under normoxic and normobaric hypoxic conditions. - To analyze the effects of whole-body vibration training on bone mineral density and bone remodelling markers of elderly, under normoxic and normobaric hypoxic conditions. - To analyze the effects of whole-body vibration training on biochemical parameters, inflammatory, endothelial and clinical markers just like cardiovascular risk level of elderly, under normoxic and normobaric hypoxic conditions. - To analyze the effects of whole-body vibration training on body composition and functional capacity of elderly, under normoxic and normobaric hypoxic conditions. - To compare the effects of circuit training with elastic bands versus whole-body vibration training on bone and cardiovascular health of elderly, under normoxic and normobaric hypoxic conditions. - To value the normobaric hypoxic environment efficacy on bone and cardiovascular health of elderly subjected to circuit training with elastic bands and whole-body vibration training. We hypothesize that bone and cardiovascular health will improve in the participants subjected to both resistance training, but greater improved may be found when these protocol are combined with normobaric hypoxia.
Admission into a pediatric intensive care unit (PICU) is a highly stressful experience for child and family. High levels of stress can negatively impact outcomes, yet non-pharmacological interventions to decrease stress in the PICU are severely lacking. This is a prospective, single-arm feasibility trial that will explore the feasibility and acceptability of a music therapy intervention to decrease stress in the PICU among families of children receiving invasive or noninvasive mechanical ventilation. Objectives: The aims of this study are to: 1) Assess the feasibility of implementing a music therapy intervention in the PICU among children receiving invasive or non-invasive mechanical ventilation; 2) Determine the acceptability of the music therapy intervention in the ICU among caregivers, patients, and pediatric and cardiac ICU staff; 3) Explore the variability in child and caregiver stress outcomes throughout ICU admission. Hypothesis: The music therapy intervention will be feasible, as determined by recruitment, retention, protocol adherence, and data collection rates, and will be acceptable to participants and to PICU staff. Sample: This study will recruit 20 families that include children aged 2 months - 17 years old admitted with an expected length of ICU stay greater than 72 hours. Of these 20 families, the investigators will specifically recruit 10 families whose child is admitted for a hypoxic brain injury. Eligible children are receiving either noninvasive mechanical ventilation (i.e., continuous or bilevel positive airway pressure), invasive mechanical ventilation, or have an established tracheostomy tube and with escalated support settings. One primary caregiver will be enrolled along with the child admitted into the ICU.
The overall objective of this project is to investigate the effectiveness of Acute Intermittent Hypoxia (AIH), to improve muscle strength and activity level in individuals with relapsing-remitting MS.
Brain tumor surgery is commonly associated with different degrees of preoperative intracranial hypertension and surrounding tumor edema, elicited by tumor underlying pathophysiology. During craniotomy for brain tumor resection maintenance of hemodynamic stability and intracranial homoeostasis is of paramount importance. Disordered hemodynamics or adverse stress may activate the immune inflammation or neuroendocrine responses and lead to a surge of inflammatory mediators and stress hormones, which are implicated in secondary brain insults. Adverse physiological responses caused by intraoperative disordered hemodynamics or surgery-related damage, may lead to some secondary brain injury (such as cerebral edema or cerebral hemorrhage), aggravating damage to brain tissue and affecting the recovery from anesthesia, cognition and prognosis in patients. Prevention of secondary brain injury is a key-endpoint to improve clinical outcomes in glioma patients undergoing craniotomy. Alpha2-adrenoceptor agonists have been widely used for sedation, analgesia and anti-sympathetic actions for many years, but the definite evidence of their potential use as neuroprotectants has so far been confined to animal studies, yet the findings are inconsistent. Dexmedetomidine (DEX) has been demonstrated to be a new type a2 adrenergic receptor (a2-AR) agonist, which can selectively bind with the a1 and a2 adrenergic receptor, and playing a dual role by restraining the activity of sympathetic nervous and stimulating the vagus nerve. Dexmedetomidine (DEX) also plays an important role in in inhibiting inflammatory and neuroendocrine responses. Animal experiments showed that the right must have a dexmedetomidine neuro-protective effect. However, the brain-protective effect of dexmedetomidine in anesthesia of craniotomy resection of glioma has not been reported. Thus, the aim of this study was to explore the effect of dexmedetomidine on perioperative brain protection, as well as cerebral oxygenation and metabolic status aiming to provide a basis for clinical rational drug use in patients undergoing craniotomy resection of glioma.
The purpose of this study is to evaluate the safety and the tolerability of CL2020 cells in hypoxic ischemic encephalopathy neonates with hypothermia therapy. In addition, we will evaluate the efficacy of CL2020 cells for infant development.
The primary purpose of this observational study was to determine if pRBC transfusions decrease the frequency of intermittent hypoxia events in very low birth weight infants (VLBW) during the first six weeks of life. The impact on non-pRBC transfusions on the frequency of intermittent hypoxia was also assessed.
The investigators designed a cross-over, randomized trial to assess the physiological effects of helmet pressure support ventilation (PSV) and continuous positive airway pressure (CPAP) as compared to high-flow nasal cannula during the early phase of acute hypoxemic respiratory failure
