The purpose of this protocol is to investigate the role of expired non-metabolic carbon dioxide in the relationship between fatigability and recovery and the response to aerobic exercise training in healthy individuals. Both fatigability and recovery are profoundly influenced by mitochondrial energetics which can be inhibited by ionic by-product accumulation during exercise. Buffering mechanisms of these fatigue-inducing ions releases non-metabolic carbon dioxide (CO2) that can be measured as expired CO2 (VCO2) during cardiopulmonary exercise testing (CPET), however the role of non-metabolic VCO2 in the relationship between fatigability and recovery has yet to be investigated. Furthermore, this study aims to identify the how the patterns of proteins in healthy individuals respond to aerobic exercise training (e.g. stationary cycling) over approximately one month. The underlying mechanisms of recovery after physical activity, including mechanisms or biological pathways that could be highlighted by analysis of proteins in urine, could add to scientific knowledge regarding physical activity tolerance and potential exercise interventions. This knowledge could eventually assist with designing precise and personalized exercise interventions to improve physical activity performance. The investigators hypothesize that 1) non-metabolic CO2 will be at least moderately associated with the inverse relationship between fatigability and recovery; and 2) highly active adults, compared to sedentary individuals, will exhibit differential proteomic patterns in response to an initial acute bout and subsequent repeated bouts of aerobic exercise.
Several studies have shown cognitive impairment such as memory, perception and learning skill during ascent to high altitudes. However, few studies have directly investigated the effect of high altitudes exposure on attention—a high-level cognitive function. Remote ischemic conditioning (RIC) is a noninvasive and easy‐to‐use neuroprotective strategy, It has been proven to be an effective strategy for neuroprotection in ischemic stroke and chronic cerebral ischemia patients.
COPD is underdiagnosed and spirometry is not widely available in primary care settings. This study explore the value of PUMA´s questionnaire in a case finding strategy to detect patients to perform spirometry in a real world scenario of primary care health venues.
Lung Protective Ventilation strategy (LPV) with low tidal volume and adequate positive end-expiratory pressure is recommended for not only patients with acute respiratory distress syndrome (ARDS) but also those without ARDS too. From previous studies, adherence to LPV strategy reported is only 40% and data is limited in surgical patients. The investigators aim to describe ventilation management and find out the adherence rate to LPV strategy applied to surgical patients admitted to the surgical intensive care unit (SICU) and their associated outcomes.
Back pain is often accompanied by changes in function. The performance of individuals with their backs on their wills may become more functional. It is believed that the test will present good to excellent reliability in individuals with chronic back pain. From this, it can be used in the clinic to verify the functional capacity of these individuals.
Background: O-GlcNAcase (OGA) is a brain enzyme. It may play a role in brain disorders like Alzheimer s disease. Researchers want to see if a new drug can be used with positron emission tomography (PET) scans to show OGA better. Researchers want to learn more about how it acts in healthy people. Objectives: To test if the new drug [18F]OGA-1 can measure its receptor. To determine whether the same results occur when scanning a person twice. Eligibility: Healthy adults age 18 and older who are already enrolled in a separate protocol. Design: Some participants will have 1 whole-body PET scan during one 4-hour visit to the clinic. Some will have 2-3 brain scans (PET and MRI) over 2-3 days. For the PET scan, a needle will guide a thin plastic tube (IV catheter) into an arm vein. A small amount of radioactive chemical will be injected through the catheter. The needle will be removed. Only the catheter will be left in the vein. Another IV catheter may be placed to draw blood. Blood pressure, heart rate, and breathing rate will be measured. Participants will have an electrocardiogram. Participants will lie on a bed that slides in and out of the donut-shaped scanner. The scan will last 2-3 hours. For brain PET scan, participants will wear a plastic mask to keep their head still. For magnetic resonance imaging (MRI) scan, participants will lie on a table. The table slides in and out of the MRI scanner. This is a metal cylinder in a strong magnetic field. Participants will be in the scanner up to 1 hour.
The relationship between the target effect site concentration of remifentanil and the pupil diameter and reactivity in response to a standard noxious stimulus in cardiac surgery during extra corporeal circulation will be evaluated.
This study compares the use of self-fixating mesh to mesh fixation with tackers in the management of inguinal hernia by laparoscopic method. Half of the participants in the study will be treated using self-fixating mesh, while the other half will be treated using conventional mesh fixed with tackers.
Evaluation of the benefit effects of Peri-Operative analgesia by Continuous Bilateral Erector Spinae Plane block(ESP) for Open Cardiac Surgery: A case series prospective study with a comparison a retrospective case series (Before and after)
The NutriNet-Santé study was set up to investigate nutrition and health relationships. Specifically, it was the first web-based cohort worldwide on such a large scale (n=160 000 as of 2017) focused on the complex link between nutrition and health status. It is characterized by a very detailed assessment of nutritional exposure and dietary behavior.
