Active clinical trials for "Trauma, Nervous System"

The on-boarding of unregulatable trauma in the United States has reached 20%, which is 1/5 of the population. A population of this magnitude, by definition has now reached an epidemic classification. The population with chronic illness as stated: PTSD, Chronic Depression, MS, HIV, and SARS-CoV-2- Long Haulers Syndrome. These chronic conditions/illnesses many lead to death and are often the cause or perpetuate unregulated trauma and create an unstable population. Psychiatrists have testified before congress that the SSSRI medications are not fully functional cures and are not working for patients. Enchanced Psilocybin micro-dosing at the levels of 0.15g. ranging to 0.33g. every other day an 0.50g. for monthly maintenance of neural pathway production is proving to shave back the highjacked nervous system, thus stopping or rerouting the ruminating neurotransmitters, by rerouting thru new neural pathways. The body has a additional natural pathway in place then to decrease/stop these thoughts by have open pathways to process the thought differently. Serotonin is a neurotransmitter and which is the most famous of all the neurotransmitters. Serotonin is very similar in its compound structure to the plant medicine family of psilocybin, serotonin and psilocybin work very similarly with the 5h2A receptor in the human cortex ( the outer cortex of the brain ). Enhanced Microdosing of psilocybin at the levels of 0.15 to 0.33 and of 1 gram to 1.5 grams monthly for maintenance of the newly opened neural pathways is postulated to be a mental health game changer. Psilocybin helps shave back the highjacked nervous system which is a condition known as the diagnosis (SSD) Somatic Symptom Disorder. This research is believed accurate by proof on previous studies to process the subconscious held in the subconscious and shave back the somatic feelings resulting from the trauma of the individuals who have on-boarded chronic disease(s) of Trauma,PTSD, Unregulated Chronic Depression, MS, Cancer, HIV, and SARS-CoV-2- Long Haulers Syndrome.

To investigate the pharmacodynamics of light chain of NFL in patients with out-of hospital cardiac arrest after successful resuscitation and determine the difference in the serum levels of NFL in patients with favorable neurological outcome compared to those with non-favorable neurological outcome.

The 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 objective of this study is to evaluate the safety and performance of occipito-cervico-thoracic spine surgery using posterior fixation as measured by reported complications, radiographic outcomes, and patients reported outcomes (PROs).This study is being undertaken to identify possible residual risks and to clarify mid-to long-term clinical performance that may affect the benefit/risk ratio of posterior fixation systems.

Both HIV infection and Covid-19 are associated to cognitive and psychiatric impairment, like anxiety and depression. These disturbs are well-known in HIV infection and partially characterized in Covid-19.

Hyponatremia occurs frequently in patients with acute brain injury in the days to weeks following injury, and may contribute to adverse outcome. In addition, hyponatremia can aggravate neurologic dysfunction, complicate neurological assessments, and contribute to neurologic symptoms such as gait dysfunction that can impair efforts at mobilization and rehabilitation. Strict normonatremia (serum Na levels between 135 and 145 meq/dl) is the goal in most patients with acute brain injury. SIADH is the most frequent cause of hyponatremia in patients with neurological injury; however, treatment with fluid restriction is often difficult or contra-indicated, for example in patients with subarachnoid hemorrhage (SAH) where intravascular hypovolemia can trigger vasospasms. The aim of this project is to test Tolvaptan, an ADH antagonist, as a treatment in selected patients with acute brain injury who have developed SIADH.

Muscle weakness is one of the most common and debilitating symptoms following a Spinal Cord Injury (SCI). Strength training is recommended as an effective means to increase muscular strength and improve function for individuals with long term SCI. In contrast, the strength training guidance for those with a recent (<1 year) SCI is lacking. Therefore, this study aims to investigate the feasibility of a method of upper limb strengthening - Progressive Resistance Training (PRT) and its impact upon muscle strength and function.

Delirium and acute neurocognitive impairment are increasingly observed in adult and pediatric patients with COVID-19. Prospective clinical studies combining clinical and laboratory examinations including specific biomarkers of neuroaxonal injury were not performed for COVID-19. The value of biomarkers of neuroaxonal injury was proven in preliminary studies. These biomarkers could thus contribute to the systematic detection of neurocognitive impairment in patients with COVID-19. Due to worldwide increasing numbers of hospitalized patients with COVID-19, biomarkers of neuroaxonal injury are highly valuable to detect and monitor cognitive impairment, especially with regard to limited resources available to perform time-consuming brain imaging. Biomarkers of neuroaxonal injury are therefore not only of great interest to detect neurocognitive impairment but also to quantify the severity of brain injury in patients with COVID-19.

Aortic dissection is a life-threatening condition and a consequence of a tear of the innermost of the three aortic layers- the intima. When a tear occurs, blood surges through the tear and causes the flow of blood between the aortic layers, causing a "false lumen". This causes a weakening of the aortic wall and hinders the blood from reaching its target organs and life saving emergent surgery is performed as routine. Approximately 20% of patients undergoing acute type a aortic dissection (ATAAD) surgery suffer from postoperative neurological injuries and It has been demonstrated that neurological injuries account for 10-15% of in-hospital deaths. In association with other cardiac procedures where the left side of the heart is opened and air may be trapped within the arterial circulation, carbon dioxide flooding is used to displace open air from the surgical wound. In comparison to air, carbon dioxide is significantly more soluble in blood and may therefore decrease the risk of air embolism. In cardiac surgery, carbon dioxide flooding has been demonstrated to reduce levels of biomarkers of cerebral injury, but carbon dioxide is not routinely employed in ATAAD surgery and has not been studied in association with these procedures. The hypothesis is that carbon dioxide flooding reduces cerebral air embolism and the aim of this project is to evaluate whether carbon dioxide flooding may reduce neurological injuries following ATAAD surgery. This is a prospective, randomized, controlled, patient- and reviewer blinded interventional study. Patients will be randomized to undergo surgery with carbon-dioxide flooding at 5L/min to the open chest cavity or conventional surgery without carbon dioxide flooding. Remaining aspects of the procedure will be identical. The patient, external statistician and the reviewer analyzing the primary endpoints will be blinded for the randomization arms. The study will assess the following endpoints: Primary outcomes: Presence, number and volume of ischaemic lesions observed using magnetic resonance imaging (MRI) after ATAAD surgery. Secondary outcomes: Clinical signs of neurological injury. Levels of biomarkers of neurological injury (S100B, neuron specific enolase (NSE) , neurofilament protein (NFL), Glial fibrillary acid protein (GFAP) , Ubiquitin carboxyl-terminal hydrolase L1 (UCH-L1) and Tau-protein (TAU)) before and after surgery. Quality of life, postoperative recovery and neurological function after ATAAD surgery. Primary outcomes in relation to retrograde cerebral perfusion. Start of inclusion is anticipated to start Jan 1st, 2022. The writing of a manuscript describing the study methods and study objectives is expected to be started in 2021 and the final manuscript is expected to be written during 2025. An interim analysis of the primary endpoints and the safety arm will be performed after 40 patients have been randomized. An external statistician together with the principle investigator will hereafter decide for the study to be continued or terminated due to harms, futility or superiority. The safety arm will include intraoperative mortality, in-hospital mortality, re-operation for bleeding, stroke, myocardial infarction or other thromboembolic events. Update August 2023: Interim analyses were performed after 40 study participants had been included. Results from the interim analyses raised important questions which need to be assessed by a Data Safety and Monitoring Board (DSMB). Since there are no documented harmful effects of the intervention, a DSMB was not appointed before initiation of the trial. The study was suspended on Aug 18th 2023. A DSMB will be appointed, analyze the interim analyses, collect necessary additional information and make a recommendation to the PI whether the study is may proceed or is to be terminated prematurely.

The safety and efficacy of MK0724 will be assessed in patients with acute middle cerebral artery stroke using the Action Reach Arm Test (ARAT). This test allows measurement of a specific functional deficit and subsequent recovery correlating with the specific area of stroke in the brain.
