Filter by:The study is to investigate the feasibility and safety of autologous umbilical cord blood transfusion to treat the newborn infants with presence of clinical indications of neonatal hypoxic-ischemia encephalopathy (HIE) and anemia. Umbilical cord blood (UCB) is collected following labor and is transfused intravenously within 48 hours after the birth. Newborn infant without UCB available recieves the standard care will be enrolled as control group. Following the autologous UCB transfusion in the study group or standard care in the control group, HIE subjects will be followed for 2 years for survival and neurodevelopmental outcomes and anemia subjects will be followed for 6 months to assess the survival and change of hematocrit and hemoglobin levels.
Patients with advanced chronic liver diseases treated at the Vienna General Hospital of the Medical University of Vienna will be offered to participate in this prospective observational trial. Clinical parameters and laboratory parameters will be recorded for all patients and patients will undergo a regular follow-up schedule with clinical visits at the Vienna General Hospital. This study is linked to a biobank with serum/plasma, ascitic fluid, urine, GI tract mucosal biopsies, liver biopsies and stool collected from the study participants.
Constipated patients often have mental problems such as depression and anxiety due to difficult defecation. Our previous studies have proved the efficacy of FMT treating constipation. Meanwhile it is believed that mental diseases are correlated to gut microbiota. This trial is based on the theory of the gut-brain-microbiota axis. Patients with constipation, depression and/or anxiety are performed FMT, laboratory, imaging and microbiota examinations, and clinical follow-up, to observe the clinical efficiency of FMT and the potential role of gut microbiome in these gut-brain disorders.
to examine the relationship between repeated concussions and late decline of brain function. In addition, all participants agreeing to participate in the study will be asked to will their brains to The Krembil Neuroscience Centre Concussion Project at the Toronto Western Hospital with the consent and full knowledge of their families and doctors. However, it is possible to participate in the research without agreeing to a brain donation. The Project Team is specifically attempting a clinical-MRI-brain tissue research analysis to determine the exact mechanism of the damage to brain tissue following repeated concussions. This condition is known as chronic traumatic encephalopathy (CTE), and shows an abnormal protein in the brain called tau-protein.
Citicoline, is a naturally occurring compound and an intermediate in the metabolism of phosphatidylcholine. Phosphatidylcholine is an important component of the phospholipids of the cell membranes. Citicoline is composed of two molecules: cyti¬dine and choline. Both these molecules enter the brain separately and by passing through the blood-brain barrier where they act as substrates for intracellular synthesis of CDP-choline . This drug has been widely used in adults who suffer from acute ischemic strokes for than 4 decades with good results and has been proved to have a very good safety profile as well. It has various therapeutic effects at several stages of the ischemic cascade in acute ischemic stroke. 1. It stabilizes cell membranes by increasing phosphatidylcholine and sphingomyelin synthesis and by inhibiting the release of free fatty acids . By protecting membranes, citicoline inhibits glutamate release during ischemia. In an experimental model of ischemia in the rat, citicoline treatment decreased glutamate levels and stroke size. 2. Citicoline favors the synthesis of nucleic acids, proteins, acetylcholine and other neurotransmitters, and decreases free radical formation Therefore, citicoline simultaneously inhibits different steps of the ischemic cascade protecting the injured tissue against early and delayed mechanisms responsible for ischemic brain injury. 3. citicoline may facilitate recovery by enhancing synaptic outgrowth and increased neuroplasticity with decrease of neurologic deficits and improvement of behavioral performance. Considering these pharmacologic properties of citicoline, we are planning to see its effects in newborns who have HIE which causes a global acute ischemic changes in developing brain.
Neonatal hypoxic-ischemic encephalopathy (HIE) is a major cause of death or long-term disability in infants born at term in the western world, affecting about 1-4 per 1.000 life births and consequently about 5-20.000 infants per year in Europe. Hypothermic treatment became the only established therapy to improve outcome after perinatal hypoxic-ischemic insults. Despite hypothermia and neonatal intensive care, 45-50% of affected children die or suffer from long-term neurodevelopmental impairment. Additional neuroprotective interventions, beside hypothermia, are warranted to further improve their outcome. Allopurinol is a xanthine oxidase inhibitor and reduces the production of oxygen radicals and brain damage in experimental, animal, and early human studies of ischemia and reperfusion. This project aims to evaluate the efficacy and safety of allopurinol administered immediately after birth to near-term infants with HIE in addition to hypothermic treatment.
The purpose of this study is to develop a database containing clinical and laboratory information for patients with Leigh syndrome. The goal is to provide a greater understanding of Leigh syndrome allowing further characterization of this disease.
The purpose of this study is to investigate the efficacy and safety of umbilical cord milking in depressed neonates at birth for prevention of hypoxic ischemic encephalopathy.
The current standard of care for patients with HE includes non-absorbable disaccharides(lactulose);The chemical name for lactulose is 4-O-β-D-galactopyranosyl-D-fructofuranose.The exact mode of action by lactulose is thought to be the conversion to lactic acid and acetic acid by colonic bacteria resulting in acidification of the gut lumen. This favors conversion of ammonia (NH3) to ammonium (NH4+), which is relatively membrane impermeable; therefore, less ammonia is absorbed by the colon. Gut acidification inhibits ammoniagenic coliform bacteria, leading to increased levels of nonammoniagenic lactobacilli. Nonabsorbable disaccharides also work as a cathartic, clearing the gut of ammonia before it can be absorbed.
This study evaluates the safety, feasibility and usability of a SaeboGlove rehabilitation device in the treatment of patients who have reduced ability to open their hand due to weakness after an acute stroke.
