Effect of Xenon on Brain Injury After Aneurysmal Subarachnoid Hemorrhage
Subarachnoid HemorrhageAneurysmal5 moreAn investigator-initiated clinical drug study Main Objective: To explore neuroprotective properties of xenon in patients after aneurysmal subarachnoid hemorrhage (SAH). Primary endpoint: Global fractional anisotropy of white matter of diffusion tensor imaging (DTI). Hypothesis: White matter damage is less severe in xenon treated patients, i.e. global fractional anisotropy is significantly higher in the xenon group than in the control group as assessed with the 1st magnetic resonance imaging (MRI). After confirmation of aSAH and obtaining a signed assent subjects will be randomized to the following groups: Control group: Standard of Care (SOC) group: Air/oxygen and Normothermia 36.5-37.5°C; Xenon group: Normothermia 36.5-37.5°C +Xenon inhalation in air/oxygen for 24 hours. Brain magnetic resonance imaging techniques will be undertaken to evaluate the effects of the intervention on white and grey matter damage and neuronal loss. Neurological outcome will be evaluated at 3, 12 and 24 months after onset of aSAH symptoms Investigational drug/treatment, dose and mode of administration: 50±2 % end tidal concentration of inhaled xenon in oxygen/air. Comparative drug(s)/placebo/treatment, dose and mode of administration: Standard of care treatment according to local and international consensus reports. Duration of treatment: 24 hours Assessments: Baseline data Information that characterizes the participant's condition prior to initiation of experimental treatment is obtained as soon as is clinically reasonable. These include participant demographics, medical history, vital signs, oxygen saturation, and concentration of oxygen administered. Acute data The collected information will contain quantitative and qualitative data of aSAH patients, as recommended by recent recommendations of the working group on subject characteristics, and including all relevant Common Data Elements (CDE) can be applied. Specific definitions, measurements tools, and references regarding each SAH CDE can be found on the weblink here: https://www.commondataelements.ninds.nih.gov/SAH.aspx#tab=Data_Standards.
RCT Evaluating Standardized Counseling on Early Discontinuation for Irregular Bleeding in Nexplanon...
Birth ControlContraception2 moreClinician counseling for implant users should involve an explanation of the likelihood of irregular bleeding and the possibility of continued or frequent bleeding throughout three years of use. If that counseling does not provide specifics of the actual distribution of bleeding patterns described in published literature, there remains the real possibility of biased or directed counseling, leading to an inaccurate and exaggerated expectation of potential bleeding changes. This study aims to evaluate if a standardized script accompanied by a visual aid regarding expected bleeding profiles, with intention to remove any possibility of negative or positive framing, could change users' expectations and satisfaction with their method, leading to lower discontinuation rates.

S100B Kinetic During the Occurrence and Treatment of Delayed Cerebral Ischaemia After a Subarachnoid...
Subarachnoid HemorrhageNearly half of the survivors of subarachnoid haemorrhage (SAH) retain irreversible neurological damage resulting from the early lesions associated with the initial bleeding, and the occurrence of possible delayed cerebral ischaemia (DCI). The early diagnosis of the occurrence of an DCI is therefore a major challenge in order to optimise management before irreversible lesions are formed. However, the means of diagnosis are often not available, and up to a third of DCI are discovered on follow-up images when the lesions are already present. Among the markers of brain injury, S100 calcium-binding protein B (S100B) is an astrocyte protein released into the bloodstream at the time of the appearance of a brain lesion. Its short half-life makes it a prime candidate for patient follow-up to diagnose a new ischemic lesion and assess the effectiveness of its management. Among the elements at the origin of DCI, the occurrence of proximal vasospasm is the main element on which we can have a therapeutic action. The strategy implemented in the department consists of performing a mechanical angioplasty when proximal vasospasm is detected with a decrease in downstream cerebral perfusion. Nevertheless the benefit of this therapeutic action is discussed and there is currently no early marker of the effectiveness of this procedure.
