NCT ID: NCT06331780 Recruiting - Clinical trials for Accommodation Disorder

Refractive Status and Accommodation Response Under Different Experimental Conditions.

Start date: February 22, 2024
Phase: N/A
Study type: Interventional

Eye Care Professionals (ECPs) massively use auto-refractors during the patient journey to measure the objective refractive error: starting point of the subjective eye refraction. These devices provide objective information about the refractive and accommodative state of the eye, useful for the ECP to perform a complete eyesight test. Auto-refractor data for the distance vision are repeatable and accurate but near vision information are not enough reliable to build an accurate near vision routine exam. Previous internal studies, with auto refractors currently on the market, have shown that, during accommodation measurements, a large proportion of participants had a lower accommodative response than expected.

NCT ID: NCT06328075 Recruiting - Clinical trials for Amyloid Cardiomyopathy

Artificial Intelligence to Assist the Echocardiographic Identification of Transthyretin Cardiac Amyloidosis

AI-ATTR-ECHO
Start date: January 1, 2022
Phase:
Study type: Observational

The goal of this study is to develop an algorithm using artificial intelligence (AI) to assist identification of potential ATTR-CM cases using routine transthoracic echocardiography. The main questions it aims to answer are: - is the algorithm able to diagnose ATTR-CM - is the algorithm able to diagnose different types of ATTR-CM (ATTRv, ATTRwt) This is a non interventional study. Participant' echocardiographies will be, after deidentification, used to train, valid and test the algorithm.

NCT ID: NCT06324968 Recruiting - Sjogren's Syndrome Clinical Trials

Ro60 Expression in Macrophages in Sjogren's Disease

RoMioSS
Start date: February 9, 2024
Phase: N/A
Study type: Interventional

Context: The Ro60 protein associates with YRNAs (or RNYs) to form the RoRNP complex, which regulates RNA surveillance and maturation. It is hypothesized that its impairment by nuclear penetration of the anti-Ro60 autoantibodies, would deregulate the anti-inflammatory response in monocytes/macrophages (Mo/Mp) in patients with Sjögren's disease (SD).

NCT ID: NCT06320639 Recruiting - Clinical trials for Neurocognitive Disorders

DRIVing Simulator and People With NeuroCognitive Disorders

DRIVS-NCD
Start date: October 3, 2023
Phase:
Study type: Observational

The ageing of the population is leading to an increasing number of older drivers on the roads. At the same time, the proportion of older people with pathological ageing and neurocognitive disorders (NCD) is increasing. In terms of road safety, this raises the question of whether these drivers should continue to drive or not. People with NCDs may not be aware of the presence, extent and progression of their cognitive impairment and the impact it can have on daily life, including driving. Despite their loss of autonomy and medical advice, 22% of people with major NCD continue to drive. In addition, the presence of minor NCD also puts people at a higher risk of road accidents. However, several studies demonstrated that an NCD does not lead to a systematic and immediate impairment of driving ability and abruptly stopping driving leads to health problems, such as the risk of depression and greatly reduces quality of life. It is therefore relevant to focus research on driving with people with NCD in order to have a reliable indicator of the person's abilities and the impact of their cognitive impairment on driving activity. The proposed study seeks to meet this need by studying the performance of people with NCD on a driving station (mini-simulator) while assessing their ability to evaluate their performance. To achieve this goal, people with NCDs will perform tasks on a driving simulator. In addition, after each task on the driving simulator, they will answer questions about how they evaluate their own driving. Two assessors will observe the participants' driving and will estimate their driving performance. By comparing the driver's self-assessment with the assessors' assessment, an "awareness score of driving ability" will be calculated to determine whether the driver correctly assessed his or her performance. Another project already underway aims to collect similar data from people without a diagnosis of NCDs (control group). The principal objective of the present study is to compare the driving performance in a simulator and the awareness of driving ability of people with NCDs with those of a control group. Secondary objectives are : 1. to measure driving performance in a simulator and awareness of driving abilities (i.e. self-assessment skills) of people with NCDs. 2. to analyse driving performance and awareness of driving abilities according to the diagnosis and severity of the disorder (i.e. minor or major neurocognitive disorders). 3. to establish a methodology to identify a driver at risk of dangerous driving. It is mainly an exploratory study however some hypotheses can be made : - The driving performance and awareness of driving skills of people with NCDs are poorer compared to those of older, control individuals. - Individuals' driving performance and awareness of driving ability are lower in the presence of major NCDs compared to minor NCDs.

NCT ID: NCT06320496 Recruiting - Clinical trials for Children With Cerebral Palsy

Evaluation of the Effect of a Physical Activity Recovery Stay

Start date: March 22, 2022
Phase:
Study type: Observational

A WHO study in 2020 revealed that 81% of adolescents (aged 11-17) do not respect the recommendation of one hour of moderate physical activity per day. In the context of disability, many factors impose limits on physical activity. While the pathology itself induces limitations and restrictions (prolonged sitting time, assisted movement, etc.), organizational constraints also apply to both children and parents, who have to divide their time between work, school and therapeutic care, which is sometimes numerous and varied over the course of a single week. These limitations generate stress and fatigue, and prolonged sedentary periods lead children with chronic illnesses, rare diseases or disabilities into a process of physical deconditioning. The accumulation of sedentary time is detrimental to cardiovascular and metabolic health. To combat this deconditioning, the 2008 National Physical Activity and Sport Plan (PNAPS) sets out the main guidelines for treatment and implementation. The plan explains that "for patients with chronic illnesses, rare diseases or disabilities, the aim is to encourage care and guidance towards Adapted Physical Activity (APA). The attending physician will be able to identify local therapeutic education programs, rehabilitation services and "sport-santé" offers, to improve access for these patients to supervised local programs". In addition, the plan suggests "developing APA programs in healthcare establishments to enable people with chronic illnesses, rare diseases or disabilities to access health education incorporating practical sessions". In line with this plan, an exercise reconditioning program has been set up at our facility. This three-month stay includes children with a variety of pathologies, but with a common feature of physical deconditioning.

NCT ID: NCT06320288 Recruiting - Clinical trials for Children With Cerebral Palsy

Analysis of Trunk and Center of Mass Control Development During Gait in Children With Cerebral Palsy (VERTEBRAL)

VERTEBRAL
Start date: September 20, 2023
Phase:
Study type: Observational

During the acquisition of posturokinetic abilities such as walking, postural control of the trunk is of paramount importance. Indeed, its development is strongly linked to the overall motor function of children. In cerebral palsy (CP), a term that refers to a set of motor disorders following a perinatal lesion, deficits in axial control are present from early childhood. These deficits are strongly correlated with the functional deficits observed in this population. In particular, during walking, deviations of the trunk (amplitudes, accelerations) are observed in the three planes of space. While recent literature increasingly questions the impact of trunk control deficit on the walking of children with CP, elements are still missing for a holistic understanding of the interaction between locomotor and postural disorders in children with CP. In particular, no study has focused on the deviations of trunk control and the center of mass (which is a global indicator of balance strategies) during the development and maturation of walking in children with CP. Therefore, the primary objective of this cross-sectional observational study will be to characterize the development of trunk control and center of mass during walking in children with CP.

NCT ID: NCT06318923 Recruiting - Multiple Sclerosis Clinical Trials

Social and Moral Cognition in Multiple Sclerosis

COSMOS
Start date: December 19, 2023
Phase: N/A
Study type: Interventional

Multiple Sclerosis (MS) is a chronic, progressive disease that affects young adults (aged between 20 and 40) and has a major impact on patients' quality of life. Cognitive disorders in MS are common, affecting 40-60% of patients. Among these disorders, the presence of social cognition disorders is common. Within social cognition, the moral judgment has been an object of research in order to understand the determinants of moral decision-making: how and why individuals make moral choices with regard to a set of prescriptions and social norms. Compared to control subjects, MS patients show a decrease in moral permissiveness, as well as an increase in moral relativity and emotional reactivity. Thus, it would seem that MS patients issue more deontological choices (lower moral permissiveness). Given that these patients also exhibit empathy deficits and higher alexithymia, these patterns are surprising. Indeed, in other clinical populations, low empathic abilities and high alexithymia are linked to utilitarian rather than deontological moral judgments. The objective of this project is to analyze the process of decision-making carried out by patients during moral dilemma situations in comparison with control individuals and verify whether the presence of a positivity bias could explain the more deontological choices made by some patients. Indeed, some work has shown that older individuals make more deontological moral judgments than younger adults. These results are also observed with young individuals when their future temporal perspectives have been experimentally constrained.

NCT ID: NCT06318780 Recruiting - Aortic Diseases Clinical Trials

Concordance of Three Imaging Methods by Dynamic CT, Contrast Ultrasound and CT Angiography in the Characterization of Endoleaks in Patients With an Aortic Endoprosthesis

LEAKDYN
Start date: February 28, 2024
Phase: N/A
Study type: Interventional

Among patients who have undergone EVAR, there is a significant risk of 20-50% endoleak. These endoleaks often require secondary interventions to reduce the risk of expansion or rupture. Currently, three-phase CT angiography and CEUS ultrasound are recommended in the post-operative monitoring of EVAR but these remain limited in characterizing the type and source of endoleak. In this study the investigators will study the interest of d-CTA for a better detection and characterization of endoleaks.

NCT ID: NCT06318767 Recruiting - Clinical trials for Peripheral Artery Disease

Predictive Value of Systolic Rise Time of the Plantar Arch on the Risk of Major Adverse Limb Events (MALE) and Major Adverse Cardiovascular Events (MACE) in Peripheral Artery Disease (PAD) at Critical Ischaemia Stage

TAMIS
Start date: March 4, 2024
Phase: N/A
Study type: Interventional

Peripheral artery disease (PAD), vascular disease of atheromatous origin, is a frequent pathology, with a steady and significant increase in prevalence over the last decades. It has various symptoms ranging from mild arterial claudication to critical limb ischemia. The critical ischaemia stage in PAD is defined by rest pain or trophic disorders and is a special situation because of the number of cardiovascular deaths at 1 year (25%), 60% at 5 years and acute ischaemic recurrence at 1 year (25%). It is a medico-surgical pathology. A haemodynamic marker is needed to monitor patients, as it is predictive of limb progression, cardiovascular events and mortality. The Systolic Rise Time (SRT) of the plantar footpad is a recently described haemodynamic measurement of proven value in the diagnosis of PAD. The aim of this study is to show the prognostic value of the Systolic Rise Time on Major Adverse Limb Events (MALE).

NCT ID: NCT06318689 Recruiting - Clinical trials for Cardiac Surgical Procedures

In Situ Exploration of Vascular Function in Vasoplegic Shock Following Cardiac Surgery With Cardiopulmonary Bypass

Vaso-shock
Start date: February 5, 2024
Phase:
Study type: Observational [Patient Registry]

The goal of this observational study is to assess in situ vascular function, glycocalyx and microcirculation in postoperative vasoplegic shock following cardiac surgery with cardiopulmonary bypass. The main question is to investigate the relationship between NO-dependent vasomotor reserve and the presence of vasoplegic shock following cardiac surgery with cardiopulmonary bypass. Participants will have two visits, during which a number of non-invasive examinations will be carried out to study glycocalyx, microcirculation and vascular function. Biological and morphological data will be collected up to 3 months after inclusion, as well as information on treatments administered and outcome. Researchers will compare a group of patients with vasoplegic shock against a group without vasoplegic shock in order to study possible alterations in function in the vasoplegic shock group.
