NCT06144359
Concussions in sports are a major public health problem because of their frequency, and are often underdiagnosed because of an unspecific clinical picture or sometimes masked by the concussion itself. Support data has been constantly evolving in recent years, including the last publication of the Berlin Consensus in 2016 specifying support in the field. However, to date, there is no tool to predict the severity of a concussion or to predict when it will return to play objectively and reliably. Brain MRI done after the head injury is most often normal. However, previous studies agree that there is a persistent electrophysiologic disturbance several weeks after the injury, and the specific pathophysiology of white matter changes after a head injury remains controversial. Diffusion tensor imaging (DTI), in addition to morphological sequences, is capable of assessing white matter microstructure and fibrous tract integrity or not. Several parameters, such as the seemingly normal white matter fractional anisotropy (FA) coefficient, the mean diffusivity and the radial diffusivity, may be altered in the aftermath of a concussion, indicating axonal damage not visible on conventional MRI sequences. Previous studies have evaluated these parameters with sometimes contradictory results: some have found an increase in AF in specific regions such as the cortico-spinal tract and the corpus callosum, others have found a decrease in AF. So far, assessment of a player's condition on and off the field after a head injury has been based on clinical criteria alone, sometimes far too subjective. The player may choose to mask their symptoms to allow them to return to the game faster, or feign more than they have. Once pathologies such as bone fractures or intracranial hematomas are ruled out by conventional imaging, there is no longer any tool for a more accurate diagnosis of possible microstructural alterations of brain tissue and for monitoring of the patient. The advent of new MRI techniques such as diffusion imaging, and particularly diffusion tensor imaging (DTI), is a promising tool to better understand white matter involvement in diffuse axonal lesions.
NCT06143501
This research project delves into the critical role of gut immunity in the occurrence and progression of acute graft-versus-host disease (aGVHD) post allogeneic hematopoietic stem cell transplantation (allo-HSCT). Addressing the current gaps in understanding the involvement of intestinal microbiota, metabolites, and cellular metabolism in clinical aGVHD, the study involves comprehensive analyses on 200 allo-HSCT patients and 50 healthy volunteers. By scrutinizing changes in gut microbiota, metabolites, and immune cell metabolism, the research aims to shed light on their roles in allo-HSCT and their correlation with post-transplant complications. The findings are poised to offer crucial insights for diagnosing and prognosticating complications following transplantation.
NCT03994887
General anesthesia (GA) is a state of loss of consciousness induced by anesthetic products. In a GA, two classes of products are usually used: on the one hand, hypnotics that are responsible for the sleep component (hypnosis) and memory loss (amnesia), and on the other hand opioids that have an analgesic role. The doses of hypnotic and morphine necessary to achieve this state of loss of consciousness and lack of response to painful stimulation vary from subject to subject, and during surgery depending on the intensity of the stimulus, requiring permanent adaptation to avoid overdose or underdosing, responsible for morbidity. Several monitors of the hypnotic component have been developed in recent years, which can now be used routinely, such as the Bispectral Index (BIS) or Spectral Entropy. However, there is currently no clinically validated technique for monitoring pain or the effect of opioids in the operating room. Spectral analysis of the electroencephalogram (EEG) revealed a significant decrease (-30%) in alpha spectral power, observed specifically in painful experimental conditions in healthy awake subjects. On the other hand, a painful experience is accompanied by transient changes in various parameters under vegetative control, whether cardiovascular, cutaneous or pupillary, essentially underpinned by the activation of the sympathetic system. The investigators hypothesize that a real-time dynamic analysis of the spectral power of EEG combined with that of cardiovascular vegetative parameters, cutaneous conductance and pupillary diameter is likely to be a marker of nociception under GA.

NCT03249207
This phase III trial will establish whether IL-1Ra, with sub-cutaneous (SC) administration twice daily for up to 21 days post aneurysmal subarachnoid haemorrhage (aSAH), improves clinical outcome as measured by ordinal shift in mRS at 6 months. Patients with SAH transferred to a neurosurgical centre will be identified and approached for study participation. Following consent, patients will be randomised to receive either IL-1Ra or placebo for a maximum of 21 days from onset of symptoms. Patients who are found to be non-aneurysmal following randomisation will be withdrawn from the study treatment. Blood samples for plasma IL-6 will be obtained prior to randomisation and at day 3-5 post randomisation for IL-6 \& IL-1 measurement. Safety will be measured at 30 days post randomisation and outcome assessed at 6 months post randomisation.

NCT00680264
The purpose of this study is to determine the radiographic and clinical outcomes of Scoliosis surgical and non-operative treatment in patients with Cerebral Palsy.
NCT04429256
Mycobacterium chimaera infections have occurred in post-cardiac surgery patients in association with contaminated cardiac bypass heater-cooler devices. So far optimal therapeutical concepts are not clear. At the University Hospital Basel Mycobacterium chimaera- infected protheses are replaced to decrease pathogenic burden and to support antibiotic long- term treatment. This study is to analyze the efficacy of this therapeutic approach.
NCT05658861
Cow's milk contains two types of β-casein: A1 and A2. The μ-opioid peptide BCM-7 is released from A1 but not from A2. BCM-7 is associated with slower gastrointestinal transit and hence increased gastrointestinal transit times. Lactose maldigesters reported an increase in abdominal pain due to consumption of milk containing A1 beta-casein as compared to milk containing only A2 beta-casein. The hypothesis of this study is that the differential abdominal pain is due to the differential gastric transit. This is a double-blinded, randomized, controlled trial conducted to determine if the transit of A1 β-casein milk is modified in the stomach as compared to milk with only A2 β-casein.
NCT05811728
Aim of the present study is to evaluate the effect of low-level laser therapy on bone quality and quantity with orthodontic tooth movement.
NCT06141213
This observational study aims to recruit pregnant women between 18 to 24 weeks of gestation to investigate the relationship between amniotic membrane thickness and fetal chromosomal abnormalities. The primary objectives are to establish whether a correlation exists between the measured thickness of the amniotic membrane and the presence of chromosomal abnormalities in the fetus, and to determine a cutoff value for amniotic membrane thickness that could indicate an increased risk of such abnormalities. Additionally, the study seeks to assess whether the inclusion of amniotic membrane thickness as a biomarker can enhance the detection rate of non-invasive prenatal testing (NIPT) and nuchal translucency (NT) for chromosomal abnormalities.
NCT06134726
the investigators study aimed to evaluate temporomandibular joint involvement in rheumatoid arthritis patients and healthy individuals 142 participants were recruited in two groups: 72 patients with Rheumatoid Arthritis (RA), and 70 healthy controls. All participants were tested for seropositivity of rheumatoid factor and anticitrullinated protein antibodies. TMD diagnosis was determined according to the standardized and validated diagnostic criteria for TMD (DC/TMD): myalgia, arthralgia, articular disc, displacement, degenerative joint disease, and headache attributed to TMD. Bruxism, a probable sleep and/or awake bruxism diagnosis was determined based on self-report and several clinical findings.

NCT06141044
Postoperative pancreatic fistula (POPF) is a major source of morbidity and mortality after pancreatic resection, especially after distal pancreatectomy (PD). Today, POPF remains one of the main causes of hospital length of stay and healthcare costs. Numerous surgical techniques have been tested to reduce its incidence without success, so the current standard for the management of POPF, and the avoidance of associated complications, is intraoperative drain placement. However, surgically placed drains are not without risk. In recent years many studies, mostly retrospective, have attempted to determine whether omission of prophylactic drainage is associated with increased morbidity. These studies suggest that patients may benefit from not having a drain placed. This evidence challenges standard practice and the debate of whether or not to place a drain after distal pancreatectomy remains open. The investigators designed a prospective multicentre randomised non-inferiority study to determine whether prophylactic intraoperative drainage is associated with a lower morbidity rate after distal pancreatectomy.

NCT04488315
According to recent studies, patients following craniotomy suffer more than minimal pain; two-thirds of patients experienced moderate to severe pain. Postoperative pain most often occurs within 48 hours after surgery. Local infiltration of anesthesia is the most simple and effective analgesia. However, the analgesic effect only lasts for a short-time after surgery, and it cannot adequately meet the needs of postoperative analgesia after craniotomy. Several studies have shown that the mixture of dexamethasone with local anesthetics could reduce the postoperative pain scores better than local anesthetics alone. Lipid microsphere is a relatively new drug delivery system. It is an artificial lipid emulsion. Studies have shown that dexamethasone lipid microsphere, the dexamethasone palmitate emulsion (D-PAL emulsion), has stronger anti-inflammatory effect than dexamethasone. Therefore, the investigators hypothesize that the pre-emptive scalp infiltration with dexamethasone lipid microsphere plus ropivacaine could achieve superior postoperative pain-relief compared to ropivacaine alone for patients undergoing craniotomy.
