Filter by:Brief Summary Cerebral Autoregulation is a well known physiological response to blood pressure changes to maintain the cerebral perfusion. The critically ill patients are submitted to different situations that can impair the cerebral autoregulation as sepsis, sedation drugs and mechanical ventilation. The delirium on ICU has been described as a bad prognosis factor, increasing the mortality and length of stay. The physiopathology of delirium has been related to cerebral perfusion. The delirium has been related to long term cognitive impairment. Material and Methods: This is a physiological prospective study that will be done in a 14 bed medical-surgical ICU. The investigators will enroll 100 ventilated patients, septic and non-septic. The investigators will measure cerebral autoregulation every 48-72 hours from admission on ICU. Neurological biomarkers (Neurological Specific Enolase, S100 beta and Vascular Endothelial Growing Factor) will be done at inclusion, 72 hours and 7 days. Clinical data, delirium presence, analytic data and ventilatory parameters will be registered every day. At hospital discharge, a psychologist will do a cognitive evaluation using specific tests. The cognitive evaluation will be repeated at 3, 6 and 12 months. Anticipate results: Some items like mechanical ventilation, sepsis and sedation can impair cerebral autoregulation. The impairment of cerebral autoregulation is related to delirium in ICU and long cognitive impairment.
This pilot clinical trial studies radioembolization and ipilimumab in treating patients with uveal melanoma with liver metastases. Radioembolization kills tumor cells by blocking the blood flow to the tumor and keeping radioactive substances near the tumor. Monoclonal antibodies, such as ipilimumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving radioembolization together with ipilimumab may kill more tumor cells in patients with uveal melanoma
Background: - Near-infrared spectroscopy (NIRS) is a functional imaging technique that can be uses light to study brain function while allowing for movement. To look at blood flow in the brain, NIRS uses a low-power light source with detectors that see how the light changes as it passes through brain tissue. Brain blood flow can indicate which parts of the brain are active during different tasks. Researchers want to study children with attention deficit hyperactivity disorder (ADHD) and autism spectrum disorders (ASD) and will use NIRS to compare the blood flow in the brain of children with ADHD and ASD with that of typically developing children. Objectives: - To see how well NIRS can detect changes in brain blood flow during tests of thinking and memory in children. - To compare blood flow in the brains of typically developing children and those with ADHD or ASD. Eligibility: - Children between 4 and 8 years of age with ASD, ADHD, or children with no psychiatric diagnoses. Design: - Participants will be screened for eligibility. Those who are taking stimulant medication for ADHD or ASD will need to stop taking it for 3 days before the study visit. - After participating in a screening assessment, all participants will have one study visit. At this visit, they will have be asked to complete two tasks during a NIRS scan. For both tasks, they will react to images on a computer screen. This visit will last about 2 hours. - This is a testing study only. No blood or other samples will be needed for this study.
To make reading this consent form easier, the word "participant" refers to you or your child (if a minor) throughout the consent form. This research is being done to study the effects of an eighteen-session strengthening program and to see if there is a relationship between the female athletes improving their landing techniques which has been proven to decrease anterior cruciate ligament injuries. Participants have been asked to take part in a research study because you are a female athlete involved in a sport that has an increased anterior cruciate ligament injury rate. The purpose of this research study is to find out if an eighteen-session strengthening program will decrease your anterior cruciate ligament injury rate. There will be approximately ninety-four (94) people in this research study at Henry Ford Health System (HFHS).
To determine if the EndoBarrier safely and effectively improves glycemic control in obese subjects with type 2 diabetes
The purpose of this study is to determine whether staining of the gastric mucosa increases the number of detected (pre)malignant foci of intestinal and diffuse type gastric cancer, in first degree relatives of individuals with familial gastric cancer.
This study is being done to compare the two anesthesia techniques which are commonly used in the formation of arteriovenous fistulas: local anesthesia and regional anesthesia. Local anesthesia means that, your doctor will inject numbing medication directly into the tissue or part of your body where the surgery will be done. In this case, the numbing medication will be injected directly into the area where your fistula will be made. In regional anesthesia, the numbing medication will be injected around the nerve (part of the body that gives sensation) for your arm, to make the entire arm numb. The purpose of this study is to compare the three month success rates of AV fistulae created by the two anesthesia techniques.
This is a prospective double-blind randomized phase II clinical trial, with two groups of intervention (one with administration of N-acetylcysteine and the other with administration of methylprednisolone), and one group of placebo. The purpose of this study is to investigate the role of N-acetylcysteine and Methylprednisolone in the modulation of warm ischemia of the liver during hepatic resection. In fact to avoid massive blood loss in liver surgery, continuous or intermittent vascular clamping of the hepatic hilum ('Pringle maneuver') is generally used with good results. However, as a consequence, ischemia and subsequent reperfusion result in complex metabolic, immunological, and microvascular changes, which together might contribute to hepatocellular damage and dysfunction. This phenomenon, known as ischemia-reperfusion (IR) injury of the liver, is a complex multi-path process leading to the activation of some inflammatory pathways. Any patient candidate to liver resection will be enrolled in the study based on the aforementioned criteria. The primary objective of the study is to assess the real efficacy of Methylprednisolone and N-acetylcysteine in reducing the secondary damage from ischemia reperfusion injury in liver resection and in reducing inflammatory response. Secondary objective of the study is whether the reduction of ischemia-reperfusion injury results in: lower incidence of postoperative liver failure, improvement of postoperative liver function, and reduction of blood components transfusions. The randomization will be done the day before the operation. The drugs will be prepared in a blind fashion by the hospital pharmacy. The hospital pharmacy will provide to each patient a drip to make bolus of about an hour before the start of the liver resection and a syringe pump for an infusion of approximately 6 hours. If the patient is enrolled and randomized in the placebo arm, he/she will receive 250 ml of glucose 5% plus the infusion of 100 ml of glucose 5% If the patient is randomized in the Methylprednisolone arm, he/she will receive a dose of 500 mg in 250 ml of glucose 5% plus 100 mg of glucose 5%. If the patient is randomized in the N-acetylcysteine arm, he/she will receive a dose of 150 mg/kg in 250 ml of glucose 5% plus N-acetylcysteine 50 mg/kg in 100 ml glucose 5%. Systematic sampling of liver function tests will be done the day before the operation, at the end of the operation, as well as in postoperative day 1, 3, 5 and 7.
A prospective, multicenter, uncontrolled study to evaluate the safety and efficacy of the Cardiapex percutaneous trans-apical access and closure system. The Cardiapex device intended for percutaneous access and closure of the left ventricular apex in conjunction with transapical Transcatheter Aortic Valve Implantation (TAVI).
Assessment of the effect of hyperoxia and hypertonic saline on survival in patients with septic shock Hyperoxia and hypertonic saline may have beneficial effects on organ perfusion and oxygenation and may reduce the organ failure occurences. To date, only scarce data are available. Side effects are not well described. Therefore we designed a randomized clinical trial in order to assess the early administration of hypertonic saline and oxygen in the very early beginning of septic shock.
