NCT ID: NCT05139732 Completed - Paralysis Clinical Trials

Exploring Functional Paralysis With Advanced Magnetic Resonance Modalities

Start date: November 4, 2022
Phase:
Study type: Observational [Patient Registry]

In functional neurological disorder (FND), neurological symptoms are present, such as paralysis, weakness and disturbed sensation of limbs, although clinically no abnormalities can be found. It is a poorly understood disorder with uncertain diagnosis, treatment and prognosis. In this study, the subtype functional paralysis is investigated with advanced neuroimaging techniques that go beyond standard clinical examinations. In previous research on FND, healthy volunteers have generally been used as a control group. However, since people with functional paralysis have similar symptoms to people with spinal cord injuries (SCI), it is intended to compare the three groups to find similarities and differences. With the proposed methods, the goal is to gain a detailed understanding of FND regarding nerve cell metabolism, diffusion pathways and neuronal networks involved in cognitive processes such as motor inhibition (reaction or no reaction depending on situation). Neurophysiological data, clinical assessments and questionnaires are carried out in addition to Magnetic Resonance Imaging (MRI). The aim is to enrol 75 participants in this study, i.e. 25 people with FND, 25 people with SCI and 25 healthy control subjects. The overall goal of the study is to find markers for FND for use in future studies to improve diagnosis and individualise therapy recommendation for both people with SCI and people with FND. Therefore, this study is a relevant step to understand FND and to diagnose this specific disease using objective MRI based diagnostic tools.

NCT ID: NCT04891991 Completed - Retinal Detachment Clinical Trials

Intravitreal Infliximab for Proliferative Vitreoretinopathy

FIXER
Start date: November 26, 2021
Phase: Phase 2
Study type: Interventional

Proliferative vitreoretinopathy (PVR) is the most common cause for failure of rhegmatogenous retinal detachment repair and is characterized by the growth and contraction of cellular membranes within the vitreous cavity on both sides of the retinal surface as well as intraretinal fibrosis. Multiple therapeutic agents have been tried as an adjunctive to retinal detachment surgery for PVR with no consistent efficacy. Tumor necrosis factor-α (TNF-α), which is a prominent inflammatory cytokine, is secreted in response to trauma, infection, and inflammation. It is a key mediator of ocular inflammation and its interactions with the retinal pigment epithelium (RPE) cell contribute to the initiation of PVR. This may occur through the action of TNF-α on the RPE cells inducing changes in cellular morphologies that lead to the formation of fibroblastic cells. Infliximab (Remicade; Janssen Biotech, Horsham, PA, USA) is a mouse-human chimeric antibody that neutralizes the biological activity of TNF-α by high-affinity binding to the soluble and transmembrane forms of TNF-α, therefore preventing the effective binding of TNF-α with its receptors. Infliximab is used in the treatment of various ocular and systemic inflammatory conditions. Furthermore, intravitreal infliximab has been used for the treatment of various ocular diseases and has proven to be generally safe for the short term in inflammatory ocular conditions. A recent study showed that intravitreal infliximab can inhibit the development of PVR and reduce levels of cytokines in an experimental dispase-induced PVR model. The purpose of this randomized controlled trial is to evaluate the efficacy of intravitreal infliximab injection as an adjunct to pars plana vitrectomy in the treatment of PVR associated with primary rhegmatogenous retinal detachment.

NCT ID: NCT04168255 Completed - Retinal Detachment Clinical Trials

Double Retinal Tamponade for Retinal Detachment With PVR and Inferior Breaks.

IRB
Start date: October 1, 2017
Phase: N/A
Study type: Interventional

Purpose To evaluate the efficacy of perfluorocarbone liquids (PFCLs) for tamponading lower retinal breaks to achieve retinal reattachment in eyes of retinal detachment with proliferative vitreoretinopathy (PVR) and inferior breaks. Patients and methods The study was prospective non comparative interventional study. It included thirty eyes of 30 patients suffering from retinal detachment with proliferative vitreoretinopathy and inferior breaks attending the ophthalmology department at Minia University Hospital. The mean age was 50.2± 10.63 years, 18 females and 12 males. Double retinal tamponade procedure were done and the patients were followed for one year. The primary outcome was to achieve successful retinal reattachment and the secondary outcome is to achieve improvement in the postoperative visual acuity.

NCT ID: NCT04139746 Completed - Retina Detachment Clinical Trials

Pneumatic Retinopexy for Severe Bullous Retinal Detachment

Start date: March 1, 2017
Phase: N/A
Study type: Interventional

To compare the efficacy and safety outcomes of scleral buckling (SB) and drainage-injection-pneumoretinopexy (DIP), a modified pneumatic retinopexy technique, in which, before injecting the gas, the drainage of the subretinal fluid is performed with a simultaneous injection of balanced salt solution (BSS) in the vitreous chamber, for the treatment of severe superior bullous rhegmatogenous retinal detachment (SBRD).

NCT ID: NCT04127526 Completed - Psychosis Clinical Trials

Psychological Therapy for Dissociation, Trauma and Voices: A Single Case Experimental Design

CONNECT
Start date: September 11, 2019
Phase: N/A
Study type: Interventional

Connection to Environment with Cognitive Therapy (CONNECT): A Single-Case Experimental Design Exploring Dissociative Experiences and Voices Emerging empirical evidence has suggested that dissociation is a robust determinant of voice-hearing in psychosis, and that dissociation mediates the link between trauma and voices. Despite the emerging evidence-base, targeted therapeutic interventions focusing on dissociation remain largely untested. The aim of the current study is to investigate whether targeting dissociation leads to improvements in distressing voices in people with a history of trauma. This will be done by delivering an eight session intervention called 'CONNECT' to six individuals within the Glasgow Psychological Trauma Service (GPTS) who hear voices, have experienced trauma and are dissociating. The intervention will focus on learning strategies to manage dissociation. It is hypothesised that reduced levels of dissociation will be associated with reduction in the frequency and distress associated with hearing voices. This study will use a randomized multiple baseline single-case experimental design, meaning that participants will be randomly allocated to a baseline of two, three or four weeks and then will begin eight weeks of Connection to Environment Cognitive Therapy (CONNECT). As well as daily measures during baseline and intervention phases, there will be four assessment points (baseline, pre-intervention, post-intervention and follow-up). The study will take approximately three months plus follow-up one month after therapy ends. Individual levels of dissociation and voices will be compared during baseline and intervention periods using visual analysis and Tau-U. This study will contribute to the evidence-based for dissociation interventions targeting distressing voices among this population. It serves to investigate the proposed mechanism in a clinical population using a therapeutic intervention. It will therefore inform clinicians of the effectiveness and feasibility of using such strategies in clinical practice and may have good generalizability to practice.
