NCT ID: NCT06347302 Not yet recruiting - Clinical trials for Rhegmatogenous Retinal Detachments

Study of Vitreoretinal Molecular Changes During Rhegmatogenous Retinal Detachment

LIPIDRET
Start date: April 2024
Phase: N/A
Study type: Interventional

Retinal detachment is a condition with an estimated incidence of between 9.5 and 18.2 cases per 100,000 individuals. It is an ophthalmological emergency that threatens visual acuity and requires surgery. However, despite satisfactory post-operative anatomical results, vitreoretinal proliferation and photoreceptor death can still have a negative impact on visual prognosis. These complications are still not fully understood. A previous study carried out by the Eye, Nutrition and Cell Signalling team at the CSGA, comparing mouse models of retinal detachment with healthy control retinas, revealed an increase in pro-inflammatory cytokines and a change in retinal lipid abundance in detached retinas. However, these results have yet to be confirmed in humans. Our main hypothesis is that the vitreous content of omega-3 PUFAs and proteins is altered during the onset of retinal detachment, since it reflects both intraocular inflammation and photoreceptor apoptosis. We therefore wish to demonstrate that the protein and PUFA contents of the vitreous humour are different between eyes with retinal detachment and eyes not affected by retinal detachment after macular surgery (epiretinal membrane or macular hole). We would like to show that the vitreous PUFA content is lower in the macular surgery group due to the absence of photoreceptor apoptosis and the absence of dehiscence causing communication between the subretinal space (photoreceptors whose membranes are very rich in PUFAs) and the vitreous space. We also hope to identify changes in the protein composition of vitreous fluid in patients with retinal detachment, with overexpression of proteins involved in inflammation pathways. In addition, we hypothesise that retinal omega-3 PUFA content is a factor influencing retino-vitreal proliferation and functional and anatomical recovery from retinal detachment. To this end, we will study the correlation between retinal PUFA-3 content and the clinical presentation and postoperative course of retinal detachment. Finally, with the aim of identifying a serum marker for the prognostic evaluation of retinal detachment, we will use as a candidate a biomarker of retinal omega-3 PUFA content that we have developed in an Age-Related Macular Degeneration (AMD) model. We will analyse the correlation between this biomarker and levels of omega-3 PUFAs measured directly in the retina. To do this, we will analyse intraoperative samples of vitreous humour, sub-retinal fluid and retinal fluid from patients undergoing vitrectomy for retinal detachment in the Ophthalmology Department of the Dijon University Hospital. A group of control patients will consist of patients operated on by vitrectomy for macular surgery (epiretinal membrane or macular hole) for whom a vitreous humour sample will also be taken. Clinical information on the characteristics of the retinal detachment will be collected. During the consultation, the patient will be questioned about any history of dyslipidaemia and any current treatment, including the use of lipid-enriched food supplements. Post-operative follow-up with prospective collection of clinical and paraclinical data on anatomical and functional evolution will be carried out up to 6 months after the occurrence of retinal detachment. A blood sample will be taken to establish a lipid profile in all patients. We will thus gain a better understanding of the changes in lipid and protein content in the vitreous humour, sub-retinal fluid and retina, and the demonstration of a link between the initial presentation and the postoperative anatomical and functional evolution of retinal detachment. This will provide a better understanding of the lipid-dependent mechanisms linked to inflammation and photoreceptor degeneration during retinal detachment, and will ultimately make it possible to develop new therapeutic strategies to improve visual prognosis.

NCT ID: NCT06330467 Not yet recruiting - Clinical trials for Dissociative Disorder

Prevalence of Dissociative Identity Disorder in At-risk Outpatient Groups Reporting Childhood Trauma.

IDENTITY
Start date: April 1, 2024
Phase: N/A
Study type: Interventional

The investigators will study the prevalence of dissociative identity disorder (DID) in three populations at risk in cases of childhood psychotrauma : patients with a diagnosis of borderline personality, patients with a diagnosis of functional dissociative crises (FDC) and patients with early psychosis. The investigators will also study the prevalence of other dissociative disorders and the frequency of complex post-traumatic stress disorder. The investigators will also look for correlations between the type of maltreatment in childhood, the age of onset of trauma and the type of diagnosis of dissociative disorders. The investigators hope to include 150 borderline patients, 150 FDC patients and 50 early psychosis patients. Data collection will be done via a psychometric administration of 7 self-completion questionnaires as well as the completion of the SCID-D semi-structured interview.

NCT ID: NCT06294847 Not yet recruiting - Retinal Detachment Clinical Trials

Ursodeoxycholic Acid (UDCA) as a Neuroprotective Adjuvant Treatment to Rhegmatogenous Retinal Detachment Surgery

UDCA
Start date: April 2024
Phase: Phase 3
Study type: Interventional

This study is indicated for patients with extended rhegmatogenous retinal detachment (RRD) (≥ 2 quadrants) with macula OFF lasting 7 days or less, pseudophakic or aphakic, and scheduled to undergo surgical intervention with vitrectomy and gas tamponade in one of the ophthalmology departments participating in the study. The main objective is to assess the effectiveness of UDCA in visual acuity recovery at 3 months (i.e., the difference between preoperative visual acuity and visual acuity 3 months after surgery) in pseudophakic or aphakic patients who have undergone successful surgical intervention (reattachment of the retina) through vitrectomy and gas tamponade following rhegmatogenous retinal detachment (RRD). 120 patients will be enrolled and randomized in two groups: - the experimental arm "UDCA Group," with oral administration of ursodeoxycholic acid (Ursolvan®) - the control group "Placebo Group," with oral administration of the placebo.

Psychoneuromentalism Disorder: A Medical Condition That Affects People With Psychological Impairments From Health Issues

PNMD
Start date: January 21, 2024
Phase: Early Phase 1
Study type: Interventional

Psychoneuromentalism Disorder is a disorder arising in the mind; that is related to the mental and emotional state of a person. It is the science of mental life. The body has a natural design to heal itself. This is a mental phenomena that cannot be explained, until now. Psychoneuromentalism Disorder is a new condition resulting from behavioral impairments, neurodiversity, and neurobehavioral dysfunctions that are related to the mental and emotional state of a participant.

NCT ID: NCT06194760 Active, not recruiting - Retinal Detachment Clinical Trials

Evaluation of Vitrectomy With ILM Peeling in Myopic Macular Hole With Only Posterior Retinal Detachment

Start date: January 1, 2022
Phase: N/A
Study type: Interventional

Retinal detachment (RD) resulting from the macular hole (MH), also known as MH-induced RD (MHRD), most commonly occurs in eyes with high myopia and results in irreversible visual disorders. Although ILM peeling for MHRD reportedly achieves a high retinal reattachment rate that ranges from 70% to 100%, the MH closure rate is relatively low, ranging from 10% to 70%.

NCT ID: NCT06166914 Completed - Retinal Detachment Clinical Trials

NCT ID: NCT06145971 Not yet recruiting - Insomnia Clinical Trials

Assessing the Impact of Brief CBTi on Dissociative Seizures: SCED

CBTi 4 DS:SCED
Start date: January 6, 2024
Phase: N/A
Study type: Interventional

Some people experience a temporary change in behaviour and consciousness, that often involves a collapse and/or shaking limb movements. These are referred to as 'Dissociative seizures'. Those who experience such seizures have been found to also display high levels of dissociation, which can be described as a change in your conscious experience and may include gaps in your memory for events. It is thought that people who experience dissociative seizures also often have difficulties with their sleep. Having difficulties with sleep may make these seizures and the amount of dissociation an individual experiences worse. Greater dissociation may be additionally linked to worsening dissociative seizures. A psychological treatment for sleep difficulties called Cognitive Behavioural Therapy for Insomnia (CBTi), has been found to be effective in reducing sleep difficulties. The main questions this study aims to answer are: 1. Does brief CBTi (bCBTi) improve sleep difficulties in those with dissociative seizures? 2. Does bCBTi reduce the frequency of dissociative seizures? 3. Does bCBTi reduce self-reported levels of dissociation in participants? 4. Does improving sleep difficulties lead to improvements in quality of life, mood and anxiety levels? 5. Is bCBTi a feasible intervention to administer in an inpatient setting? This study will investigate whether improving sleep by administering a brief version of CBTi leads to an improvement in levels of dissociation and dissociative seizure frequency. It will also investigate whether brief CBTi is a feasible treatment method for sleep difficulties in an inpatient setting. Participants who have dissociative seizures and sleep difficulties that could be diagnosed as insomnia will be randomly assigned to a baseline phase of 5, 7 or 9 days, where they will fill out daily questionnaires on their sleep, dissociation and number of seizures. They will then begin a 10-day intervention phase where they will attend two sessions of brief CBTi, whilst also completing daily measures. This will allow us to see whether their scores on the sleep and dissociation measures improve when the intervention begins. Participants will be asked to wear an Actiwatch during the night, to gather information on their movement levels during the night. Information on changes in quality of life, mood and anxiety levels following the sleep intervention will also be collected.

NCT ID: NCT06056596 Recruiting - Retinal Detachment Clinical Trials

Lamivudine and Plasma Markers of Inflammation in Retinal Detachment

Start date: January 30, 2024
Phase: Early Phase 1
Study type: Interventional

The goal of this clinical trial is to test whether an oral medication (lamivudine) enters the eye and reduces blood markers of inflammation in people who undergo retinal detachment surgery (pars plana vitrectomy). Participants will take the study medication or placebo, and the researchers will measure blood markers of inflammation before and after surgery. The researchers will also measure the amount of medication in the blood and fluid inside the participant's eye (which is collected during surgery).
