Feasibility and Utility of Artificial Intelligence (AI) / Machine Learning (ML) - Driven Advanced...
CholecystitisCholelithiasis1 moreThe goal of this study is to evaluate the utility and efficacy of an artificial intelligence (AI) model at identifying structures and phases of surgery compared to traditional white light assessment by trained surgeons. Surgeons will perform the procedure in their standard practice, while the AI model analyzes data from the laparoscopic camera. Surgeons will be asked to audibly state when they identify structures and enter different phases of the surgical procedure. The AI will not alter the surgeon's view or be visible to the surgeon, and the surgeon will perform the procedure in the exact same fashion as they typically do.

An Open-Label Tolerability and Exploratory Efficacy Study of Zonisamide for Dyskinesias in Parkinson's...
Parkinson DiseaseParkinsonism1 moreIn this 12-week, open-label pilot study, the investigators will enroll 20 subjects with Parkinson's Disease to determine if two doses of Zonisamide are tolerable and demonstrate clinical benefit for Dyskinesias. The primary outcome measure is tolerability, as determined by number of subjects able to complete the study on their originally assigned dosage. Secondary outcome measures will use the Unified Dyskinesia Rating Scale (UDysRS), comprised of an Objective Section and a Historical Section, to compare baseline to 6 and 12-week measurements. Additional analysis of the effect of Zonisamide on quality of life will be measured by the Parkinson's Disease Quality of Life Questionnaire (PDQ-39).
High Resolution Micro OCT Imaging
Cystic FibrosisCOPD3 moreThe purpose of this study is to learn about using the imaging to make images of the lungs and nose with the long-term goal of the research leading to potential treatments and new therapies for patients with cystic fibrosis.
Multiple Breath Washout, a Clinimetric Dataset
Cystic FibrosisPrimary Ciliary Dyskinesia4 moreMonitoring patients with chronic, inflammatory airways disease particularly in the early stages is hampered by the relative insensitivity of current outcome measures to detect subtle changes. Multiple breath washout is a potential sensitive test that is a useful readout of disease at these early stages but it lacks standardisation and knowledge of variability with reference to standard lung function measures. This is a Cross sectional and longitudinal observation study. The hypothesis is that multiple breath washout-derived indices will provide a robust signal of gas mixing inhomogeneity, correlating with conventional measures of airway disease severity. Multiple breath washout performed on different devices will generate indices which correlate but differ in value.
Defining the Genetic Etiology of Suppurative Lung Disease in Children and Adults
Primary Ciliary DyskinesiaPrimary Immune Deficiency1 moreThe investigators will utilize a systematic approach for the diagnostic evaluation of patients to identify characteristics which may distinguish between Primary Immunodeficiency (PID) disorders versus Primary Ciliary Dyskinesia (PCD).

DCP (RaDiCo Cohort) (RaDiCo-DCP)
Primary Ciliary DyskinesiaPrimary Ciliary Dyskinesias (PCD) are rare, autosomal recessive respiratory diseases, due to a defect in mucociliary clearance linked to abnormalities in the structure and/or function of the cilia. The variety of ciliary abnormalities identified reflects the genetic heterogeneity of PCDs. The thirty or so genes currently implicated explain the pathology in about half of the patients. PCDs are characterized by recurrent infections of the upper (rhinosinusitis) and lower (bronchitis) airways, beginning in early childhood and progressing respectively to nasal polyposis and bronchial dilatation. In half of the cases, there is a lateralization defect of the organs (situs inversus) corresponding to Kartagener's syndrome. There is more frequent infertility in men (immobility of spermatozoa) than in women (miscarriages and tubal pregnancies). About a third of patients progress to respiratory failure. The identification of predictive factors of severity, specific to PCDs, would improve patient care. It is also important to assess the quality of life of patients with PCD, particularly at the ENT level. Data from prevalent patients are currently integrated into three separate and complementary databases: the "e-RespiRare" database, the "DCP Cils" database and the "DCP genes" database. The first step is therefore to constitute the RaDiCo-DCP database which will include data from prevalent and incident patients whose diagnosis of PCD is certain. The cohort aims to improve the routine care of PCD patients, in particular by highlighting predictive factors of severity, allowing early and personalized care, to assess the social impact (quality of life) and medical conditions of ENT impairment, as well as adult infertility, to finely characterize the ciliary phenotype. The study also aims to search for new DCP genes and to allow genotype/phenotype correlation studies.
Subthalamic Nucleus Stimulation With Directional Leads on Patients With Parkinson Disease at Fluctuations...
Parkinson DiseaseSubthalamic Nucleus Stimulation1 morePatients with subthalamic nucleus have to go through a lot of examinations and tests, before and after surgery which is difficult, sometimes painful, for the patient. The investigators used to chose the best plot of the leads for stimulation by a procedure long and exhausting for the patient and the examinator. The investigators can chose the plot using a software (Guide Xt), which can delete the exhausting test. The investigators would like to study the non inferiority of this tool to choose the best plot .
The Ear-Nose-Throat (ENT) Prospective International Cohort of PCD Patients (EPIC-PCD)
Primary Ciliary DyskinesiaKartagener SyndromeThe Ear-Nose-Throat (ENT) Prospective International Cohort of patients with Primary Ciliary Dyskinesia (EPIC-PCD) is a prospective observational clinical cohort study, set up as a multinational multi-centre study. It is embedded into routine patient care of participating reference centres for PCD and patients keep being managed according to local procedures and guidelines.
