Treatment of Neonatal Encephalopathy With Oral Sildenafil Suspension to Repair Brain Injury Secondary...
Neonatal EncephalopathyAround the time of birth, some babies experience a condition called asphyxia, which means that their brain and other organs do not receive enough blood and/or oxygen to work properly. This life-threatening condition accounts for nearly 1 out of 4 deaths of all babies around the world, and often leads to severe brain damage, cerebral palsy, epilepsy, and trouble with learning and functioning in everyday life. At this time, no treatment is available to repair the brain damage caused by asphyxia. Excitingly, a drug called sildenafil (Viagra®) is already given safely to babies who suffer from increased blood pressure in their lungs' vessels. Recent studies using a laboratory model of asphyxia at birth suggest that sildenafil may also repair the brain damage caused by asphyxia. Similarly, recent small studies have shown that it is both feasible and safe to give sildenafil to human babies, who suffered from asphyxia at birth. These studies also highlight the first promising signs that sildenafil may improve how the brains of these babies work, which is consistent with the abovementioned laboratory studies. On the basis of these previous researches, the investigators predict that sildenafil can repair the damage to a baby's brain. The investigators will test whether sildenafil can be safely given to a large group of human babies who suffer from asphyxia at birth, and will confirm whether sildenafil improves or not how their brains and hearts/lungs work. This project will enable to determine whether sildenafil is a promising treatment for repairing brain damage in babies who suffer from asphyxia at birth. This project may also provide new solutions for these babies to improve their future life.
Respiratory Muscle Training in Acquired Brain Injury Patients.
Respiratory DiseaseMuscle Weakness3 moreBackground: Respiratory health problems are one of the main causes of morbidity and mortality in adult people with acquired brain injury (ABI). The influence of respiratory muscle training has not yet been studied in this population group. The objective of the study was to evaluate and compare the efficacy of two protocols with respiratory muscle training, inspiratory muscle training vs expiratory muscle training, to improve respiratory strength and pulmonary function in adults with CP. Methods: The study is a controlled, randomised, double-blind trial and with allocation concealment. 26 ABI patients will be recruited and randomly distributed in the inspiratory muscle training group (IMT) and the expiratory muscle training group (EMT). Over an 8-week period an IMT or EMT protocol was followed 5 days/week, 5 series of 1-minute with 1-minute rest between them. IMT trained with a load of 50% of the maximum inspiratory pressure (MIP) and EMT with 50% of the maximum expiratory pressure (MEP). Respiratory strength and pulmonary function were evaluated.
FFP In Traumatic BRAin INjury (FIT-BRAIN) Trial
Moderate to Severe Traumatic Brain InjuryThe goal of this clinical trial is to learn about treatment with fresh frozen plasma (FFP) in individuals with moderate to severe traumatic brain injury. The two main question[s]it aims to answer are: Is the FFP treatment safe? Does the FFP treatment impact the 24-hour and 6-month outcomes, intensive-care free days, mortality, and hospital brain and physical function at discharge. Patients with moderate to severe TBI will randomly receive either: Standard of care treatment Standard of care treatment + 2 units of FFP. Researchers will compare participants receiving standard of care treatment to those receiving experimental fresh frozen plasma (FFP) treatment to see if the FFP is safe and beneficial to participant outcomes.
Long Term Efficacy and Tolerability of AP707 in Patients With Chronic Pain Due to Central Neuropathy...
PainPain Syndrome12 moreOver the last years a rising medical need for treatment of chronic pain was identified. Based on previous findings indicating the pain modulating effects of cannabinoids in chronic pain disorders, this clinical trial investigates the long term efficacy and tolerability of the THC-focused nano endocannabinoid system modulator AP707 in patients with chronic pain disorders due to central neuropathy of any genesis. Patients receive AP707 or placebo over the course of 14 weeks as an add-on to the standard of care. Changes in pain intensity, quality of life and sleep and others measures are monitored through different scales to assess the efficacy of AP707 in patients with chronic pain due to central neuropathy of any genesis.
Use of Cerebral Biomarkers in Minor Traumatic Brain Injury in the Emergency Unit
Brain InjuriesTraumatic3 moreThe use of serum biomarkers in the setting of the emergency department (ED) has been well characterized over the years as an adjunctive tool for the clinician in the setting of complex decision making. In this regard, the serum dosage of glial fibrillary acidic protein (GFAP) and ubiquitin C-terminal hydrolase L1 (UCH-L1) has been evaluated in a series of successful multicenter prospective studies as a potentially useful marker of, respectively, glial and neuronal damage in the setting of mild traumatic brain injury (mTBI), which is defined as a brain injury (concussion) secondary to trauma with a GCS (Glasgow coma scale) score of 13-15. It seems that both markers are detectable in serum less than 1 hour after the traumatic event, with highest levels appearing at around 2 hours, and are capable of distinguishing between patients with traumatic brain injury from those without acute brain injury after trauma. Furthermore, they seem to possess a high negative predictive value for detection of intracranial injuries at head CT-scan as well as the need of neurosurgical intervention after head trauma. Mild traumatic brain injury is one of the most frequent chief-complaints for patients presenting to emergency departments worldwide. At present, head CT scan is the gold standard diagnostic test for the identification of potentially life-threatening intra-cranial injuries. Although effective in the identification of serious lesions which might require neurosurgical intervention or in-hospital prolonged observation, the extensive use of head CT scan in mTBI has been questioned due to the potential risks related to radiation exposure, as well as unnecessary deployment of ED resources and increased costs, considering that the prevalence of CT-detected intra-cranial injury in mTBI is around 5-10%. For this reason, a number of international clinical guidelines suggest several Clinical Decision Rules (CDR) and algorithms to guide the clinician in the correct management of these patients, in particular in the difficult feat of identifying those patients who don't need to perform neuroradiological evaluation (CT scan or MRI) in the setting of the ED, without the risk to overlook potentially fatal brain injuries. The adjunctive role of these biomarkers has been well characterized in the setting of mTBI. It seems they correlate well with neurological damage as well as with the presence of CT abnormalities, and it seems that they might perform better than clinical evaluation alone. Nonetheless, according to current international guidelines and several systematic reviews and meta-analysis, patients who present with mTBI and risk factors for bleeding and delayed bleeding (such as known coagulopathy, patients on blood thinners or advanced age), need to perform CT scan plus clinical observation or even serial CT scans when the risk of delayed bleeding is considered to be high according to clinical evaluation of the ED physician and according to local standard-of-care and clinical practice. The execution of serial CT scans can be time consuming, expensive for the health-care services, and might pose a significant radiological risk for patients; furthermore, this risk might be unjustified considering that the prevalence of development of late intra-cranial bleeding in patients with risk factors who perform a second head CT scan during observation in the ED is considered to be around 2%. Nonetheless, in this category of patients, clinical observation and the repetition of a second head CT scan is felt to be the safest course of action for patients in order not to overlook potentially fatal injuries. Ideally, a clinical decision algorithm which takes into consideration a serum biomarker with a high negative predictive value for brain injury might aid the clinician to reduce the number of useless CT scans, therefore reducing the observation time in the ED as well as the exposure to ionizing radiations for the patients, while not increasing the number of missed delayed bleedings. At present, the role of GFAP and UCH-L1 in the risk stratification of patients with risk factors for delayed cerebral bleeding after mTBI has not been evaluated yet.
the Effects of Hyperbaric Oxygen on Non-acute Traumatic Brain Injury
Traumatic Brain InjuryTraumatic brain injury (TBI) continues to be a major cause of death and disability throughout the world. The reduced cerebral blood flow secondary to the direct trauma-induced damage deregulates cerebral metabolism and depletes energy stores within the brain. Diffusion barriers to the cellular delivery of oxygen develop and persist. Besides, TBI often leads to intracranial hypertension, which in turn exacerbates diffusion disorders, further reducing cerebral oxygenation, and deteriorates the injury. By increasing the partial pressure of oxygen in blood, reducing intracranial pressure and cerebral edema, Hyperbaric oxygen therapy (HBO2) has been used in early treatment of TBI. However, due to the different severity of TBI, the clinical situation of early insult is complex and unpredictable, ordinarily there was a time delay between TBI and onset of HBO2 treatment averaging more than 2 weeks, especially in patients with severe TBI. Whether the delayed intervention is still effective is controversial.

Ketamine in Severe Traumatic Brain Injury
Traumatic Brain InjuryTraumatic EncephalopathyTraumatic brain injury (TBI) accounts for approximately 2.5 million visits to emergency departments in the United States each year. After decades of research, management strategies for severe TBI (sTBI) patients are still evolving. Optimizing intracranial pressure (ICP) and cerebral perfusion pressure (CPP) are paramount in the management of these patients and placement of these monitors is the current standard-of-care. However, monitoring brain oxygenation (PbtO2) with invasive intraparenchymal monitors is currently under investigation in the management of severe TBI and placement of these monitors is gaining widespread use. This has opened the door for the use of tiered therapy to optimize ICP and PbtO2 simultaneously. Current evidence indicates that correction of ICP, CPP and PbtO2 in sTBI requires optimized analgesia and sedation. Ketamine is one of the few drugs available that has both sedative and analgesic properties and does not commonly compromise respiratory drive like opioids and sedative-hypnotics. However, traditionally, ketamine has been viewed as contraindicated in the setting of TBI due to concerns for elevation in ICP. Yet, new data has cast this long-held assumption into significant doubt. Hence the present pilot study will characterize the neurophysiological response to a single dose of ketamine in critically-ill TBI patient with ICP and PbtO2 monitoring.
