This study is a retrospective study trying to find the predictive factors for medullary thyroid aggressiveness in terms of tumor metastasis and patients' survival.
Stroke is worldwide the second most common cause of death following heart attack and the leading cause of disability. Post-stroke fatigue (PSF) is a common complication after stroke and can be defined as 'an overwhelming exhaustion or tiredness, not related to exertion, which does not typically improve with rest'. Fatigue following stroke can be divided into early (< 3 months) and late (> 3 months) fatigue. PSF can have a considerable impact on a person's everyday activities and quality of life, participation in the rehabilitation process and levels of caregiver burden. Yet no efficient treatment exists to prevent or cure PSF because the pathophysiology remains unclear and seems to be multifaceted. Autonomic dysfunction is a common complication after stroke, associated with higher morbidity and mortality. An easy tool to measure the function of the autonomic nervous system (ANS) is heart rate variability (HRV), which is defined as the beat-to-beat variation of the heart rate (= interbeat interval (IBI)). It is the result of alterations in the sympathetic and parasympathetic nervous system. In recent systematic reviews, authors stipulate that HRV can be regarded as a prognostic factor for short- and long-term stroke outcomes. HRV can be derived from 24 hours, 5 minutes (short-term) and < 5 minutes (ultra-short-term) measurements by applying time-domain and frequency-domain indices. Autonomic dysfunction has been related to chronic fatigue syndrome, in addition to fatigue in multiple sclerosis, Parkinson's disease and myasthenia gravis. However, to the best of our knowledge, the relationship between autonomic dysfunction and PSF has not yet been fully investigated. Fatigue is also common in cardiovascular diseases, especially in patients with heart failure (HF). HF can contribute to fatigue after stroke, independently of stroke. Cardiac complications after acute ischemic stroke (AIS), such as arrhythmias, cardiac dysfunction and myocardial injury, are frequent. The so-called 'stroke-heart syndrome', a concept introduced in 2018, describes a broad spectrum of cardiac changes observed in 10-20% of patients with AIS within the first month after stroke onset, with a peak in the first 72 hours. A dysregulation in the neural-cardiac control after stroke is suspected to be the cause of the cascade leading to cardiac complications, in which autonomic dysfunction and inflammation seem to be part of the underlying mechanism. Based on previous studies and by analogy with other neurological diseases, the investigators hypothesize that autonomic dysfunction following AIS contributes to PSF and that patients presenting heart failure as a complication following AIS have an increased risk of PSF. To confirm this hypothesis, the investigators will conduct a prospective, interventional study where patients who are hospitalized at the Stroke Unit, within 72 hours after stroke symptom onset, will be included. Evaluation will take place of (a) the relationship between autonomic dysfunction (HRV) and early and late PSF, and of (b) the relationship between cardiac dysfunction and early PSF and late PSF. There will also be an investigation into following elements: - the association between early and late PSF and (a) certain inflammatory markers at admission (CRP, NLR), (b) stroke localization and (c) baseline imaging markers of brain frailty. - the role of pre-existing fatigue + pre-existing or post-stroke newly diagnosed cognitive impairment, depression and sleep disturbances on the course of PSF.
The goal of the study is to determine the benefit of using an ECochG-based corrective action guide during cochlear implant surgery compared to the traditional surgical approach without ECochG surveillance and guidance.
The COMPRESSED project is a descriptive, bi-centric and non-invasive study carried out by the CERIAH - IDA - Institut Pasteur and the Haute École Léonard de Vinci in Brussels on volunteer participants identified in two groups : - be subject to high exposure to compressed sound, as defined by professional participation in events on broadcast platforms using sound signal processing systems, over the last 3 years, - be subject to moderate or limited exposure to compressed and manipulated sound, equivalent to that of a student following certain distance learning courses. on a videoconferencing platform, alternating with other face-to-face courses, with the ability to listen during breaks, which have been taught for a maximum of 2 years. The main objective of the COMPRESSED study is to evaluate the auditory effects of exposure to manipulated sounds (compression, filtering, equalisation, accentuation, etc.) from sound distribution platforms on the auditory system of participants who are regularly exposed to these sounds as a result of their professional activity.
Arthroscopical reconstruction of the volar and dorsal part of the scapholunate ligament as treatment for complete scapholunate ligament injury, but reducible carpal malalignment. This prospective study aims to evaluate the clinical and functional outcome of this technique on the short and middle term
The goal of this clinical trial is to evaluate two treatment strategies in patients with chronic atrial fibrillation and heart failure, who are eligible for atrial fibrillation ablation. Patients will be randomized to either atrial fibrillation ablation or to implantation of a pacemaker with conduction system pacing followed by atrioventricular node ablation. The effect of treatment allocation on total mortality, cardiovascular hospitalization and heart failure hospitalization will be compared.
This study was designed to compare the efficacy and safety of I-DXd with treatment of physician's choice in participants with relapsed small cell lung cancer (SCLC).
The goal of this observational study is to learn more about the effect of obstetric epidural anesthesia on regional lung ventilation in healthy parturient women. The main question it aims to answer is whether the initiation or epidural analgesia improves or not regional lung ventilation in healthy women at term during labor. Participants will be subject to measurements of pulmonary impedance by electric impedance tomography before and after the start of epidural analgesia. No change will be applied to clinical care as a result of this measurement.
The goal of this clinical trial is to investigate the short-term effect of a structured, combined postural control and gaze stabilisation protocol (VIS-REHAB protocol) in a group of vestibular-impaired children of different age categories (3-17 years). The main questions it aims to answer are: - What is the short-term effect of the VIS-REHAB protocol? - What are the most important factors that may influence the effect of and outcome after application of the VIS-REHAB protocol? The participant will undergo both an active rehabilitation program (VIS-REHAB protocol) and a period during which physical therapy is discontinued (CTRL protocol).: - VIS-REHAB protocol: Postural control (static and dynamic postural stability exercises), gaze stability exercises (oculomotor function and VOR-exercises) & general gross motor training with focus on gaze stability and postural control. Researchers will compare the VIS-REHAB protocol with receiving no therapy (CTRL protocol) to evaluate potential enhancements in postural stability, gaze stability, motor performance and quality of life.
In this trial, the investigators introduce two internet-based psychological methods to meet the currently unmet medical need to cope with Fear of Cancer Recurrence (FCR) beyond the acute phase of cancer treatment: internet-based emotional freedom techniques (iEFT) and internet-based mindfulness intervention (iMMI). The primary aim of this trial is to examine the efficacy of Internet-Based Emotional Freedom Techniques (iEFT) and Internet-Based Mindfulness Meditation Intervention (iMMI) to alleviate Fear of Cancer Recurrence (FCR) in cancer survivors, as determined through the Fear of Cancer Recurrence Inventory (FCRI) in cancer survivors. To translate a statistically significant effect on FCR into a clinically significant change, the investigators would need to detect a between-group difference in mean FCRI at T1 of 10 points using an independent samples t-test (two experimental groups are compared against a single wait-list control). When the application of iEFT and/or iMMI appears effective to reduce FCR, these self-help methods could be implemented in clinical settings. The use of these low cost interventions with a low threshold, by an internet-based approach, will facilitate a potential implementation in clinical practice.
