NCT ID: NCT05942677 Active, not recruiting - Clinical trials for Flat Colorectal Lesion

Comparison of Flat Colorectal Lesion Detection by Artificial Intelligence-assisted Colonoscopy Versus Endoscopists

AIChallengeMed
Start date: January 1, 2022
Phase:
Study type: Observational

The development of artificial intelligence (AI) systems in the field of colorectal endoscopy is currently booming, colorectal cancer being, by its frequency and severity, a real public health problem. In terms of image analysis, AI is indeed able to perform many tasks simultaneously (lesion detection, classification, and segmentation) and to combine them. Lesion detection is thus the starting point of the whole chain to choose at the end the most appropriate treatment for the patient. Large-scale studies have demonstrated the superiority of artificial intelligence-assisted detection over the usual detection by gastroenterologists, mainly for the detection of sub-centimeter polyps. However, the investigators have shown that a recent computer-aided detection system (CADe) such as the ENDO-AID software in combination with the EVIS X1 video column (Olympus, Tokyo, Japan) may present difficulties in the detection of flat lesions such as sessile serrated lesions (SSLs) and non-granular laterally spreading tumors (LST-NGs). This represents a major challenge because in addition to their shape being difficult to identify for the human eye in practice and where AI assistance would be of great value, these rare lesions are associated with advanced histology. In addition, the investigators recently described the case of a worrisome false negative of AI-assisted colonoscopy, which failed to detect a flat adenocarcinoma in the transverse colon. Therefore, it is important to measure the false negative rate of AI detection based on the macroscopic shape of the lesion. Comparing this rate to the human endoscopist's false negatives would improve the performance of AI for this specific lesion subtype in the future.

NCT ID: NCT05930769 Active, not recruiting - Myoma;Uterus Clinical Trials

Retrospective Study on the Evaluation of the Impact of Augmented Reality Usage in Gynecological Laparoscopy on Patients Operated Between 2017 and 2021 (ImpactRA)

ImpactRA
Start date: June 1, 2022
Phase:
Study type: Observational

ImpactRA is an observational retrospective study. The management of the patient is not modified by this study. This study will be carried out based on the already existing data of the gynecological ward of CHU Clermont-Ferrand between 2016 and 2021. During this period of time, 17 patients have undergone laparoscopy, with surgical indication of myomectomy or adenomyomectomy, aided by augmented reality (AR). The investigators compared these 17 patients that underwent surgery with AR with 17 control patients that underwent the same surgery with the same indication but without AR.

NCT ID: NCT05927454 Active, not recruiting - Clinical trials for Still's Disease, Adult-Onset

Acostill ( RaDiCo Cohort) (RaDiCo Acostill)

Acostill
Start date: July 11, 2017
Phase:
Study type: Observational

Adult Onset Still Disease (AOSD) and Systemic onset Juvenile Idiopathic Arthritis (SoJIA) are two rare multifactorial diseases associated with systemic inflammation. These two forms AOSD and SoJIA are considered to be two facets of the same syndrome, combining four cardinal symptoms [hectic fever> 39 °, arthralgia or arthritis, skin rash, a leukocyte formula with more than 80% of neutrophils]; lymphadenopathy and splenomegaly may also be found. There is an important biological inflammatory syndrome with elevation of the reactive C protein, of serum ferritin with a dramatic drop in the glycosylated fraction. The incidence of the disease is low, around 0.1/100,000 for adults and 0.6/100,000 for children. Its prevalence is approximately 1 to 3/100,000 and 3/100,000 for children, so there are approximately 500 to 1,500 adults and 450 children affected in France. It is subdivided into pediatric and adult forms according to the age of onset before or after 16 years. The prognosis of the disease is functional and vital. Macrophage activation syndrome (SAM) is frequently associated with either the onset of the disease or the initiation of treatment or concomitantly with viral reactivation. The course over time has mainly been studied in children and is variable: regression, course by flare-ups with term regression and chronic joint development. In adults we can also observe these 3 evolutionary modes. However, differences seem to exist between AOSD and SoJIA. The various clinical questions posed by this disease are as follows: - Why does it differentially affect two age groups of the population? - Why is the clinical expression heterogeneous with pure systemic or articular forms, the frequency of SAM, and rare organ damage? - Why is the evolution over time different with resolving monocyclic forms or polycyclic forms and sometimes chronic evolutions? These differences could be explained by distinct underlying pathogenic mechanisms. But at present, the pathophysiology of this entity remains unknown, although several hypotheses can be formulated involving several pathophysiological pathways. The pathogenesis of Still's disease has not yet been elucidated but there is a significant inflammatory reaction without the production of autoantibodies, which makes this disease a form of autoinflammatory syndrome with abnormalities of the innate immunity (activation of macrophages, strong elevations of pro-inflammatory cytokines: interleukins 1 and 18, possible abnormalities of inflammasomes and NK cells). The treatment is based on anti-inflammatory drugs, corticosteroids with the usefulness of methotrexate and anti-TNF in the event of significant joint damage. Interleukin 1 and 6 inhibitors have been shown to be effective in this disease. In adults and children, there are forms that are refractory to treatment, with a risk of AA amyloidosis for these patients. The expected outcomes of this work are to improve knowledge of Still disease and patient management on the following aspects: - Comparison of pediatric and adult forms (which has never been done on a large number of patients), - Better understanding of the pathogenic mechanisms of the disease, - The identification of early diagnostic/prognostic markers, - The possibility of promoting the evaluation of new therapies to come thanks to the constitution of an active file of patients with a standardized follow-up. The ACOSTILL study group is thus a unique collaboration of adult clinicians (rheumatologists and internists) and pediatricians, who have decided to unite their efforts to increase knowledge about the pathogenesis of Still disease in order to better understand the disease and improve care pathways. Many of them participated in the development of the national diagnostic and care protocol published in 2018.

NCT ID: NCT05917509 Active, not recruiting - HIV Infections Clinical Trials

A Study to Evaluate the Efficacy, Safety, Participant Choice and Preference of an Oral Once-daily Regimen or a Long-acting Injectable Regimen Every Two Months for Treatment of Human Immunodeficiency Virus (HIV-1) in Adults Who Have Not Previously Taken Antiretroviral Therapy

VOLITION
Start date: July 6, 2023
Phase: Phase 3
Study type: Interventional

This is a multicentre study carried out in participants living with human immunodeficiency virus type 1 (HIV-1) who have not previously been treated with any antiretroviral therapies. The study will investigate two 2-drug regimens for the treatment of HIV-1: a fixed-dose combination oral tablet of dolutegravir/lamivudine (DTG/3TC) and cabotegravir plus rilpivirine long-acting agents (CAB + RPV LA). All participants will initially receive DTG/3TC once daily, and once virologic suppression is attained (plasma HIV-1 <50 c/mL), participants will be offered a choice to switch to CAB + RPV LA or to continue taking oral DTG/3TC. This study will provide important data on the efficacy, safety, implementation effectiveness, and patient-reported outcomes of these two regimens in a study where participants have the option to choose between them based on individual preference. The aim of the study is to evaluate the antiviral effectiveness at 11 months after switching to CAB+RPV LA following initial virologic suppression on DTG/3TC and to provide data on how long it takes participants to suppress their viral load on DTG/3TC.

NCT ID: NCT05910164 Active, not recruiting - Clinical trials for Patient Satisfaction

Patient Preference Between a Prefilled Syringe or a Prefilled Pen Device for Administration of Pegfilgrastim

PELGRAZ
Start date: June 9, 2023
Phase:
Study type: Observational

Febrile neutropenia (NF) is a common serious complication of cancer chemotherapy. Outpatient management of chemotherapy treatments is made essential by the volume of patients treated, respect for their quality of life and the lack of hospitalization resources. The prevention of NF is well documented and its success depends on the risks of developing NF related to the type of chemotherapy protocol used and the profile of the patient and his disease. Pegfilgrastim (G-CSF, biosimilar medicine) injection has been shown to prevent (febrile) neutropenia. It is routinely prescribed on an outpatient basis for patients treated with chemotherapy (CT), several thousand times a year in our geographical area. In order to take into account patient preferences and help clinical decision-making, this study will be conducted on the basis of self-administered questionnaires. The aim of the research is to assess patient preference for receiving administration of PELGRAZ (Accord Healthcare) using a prefilled syringe or a prefilled pen device. In a second step, this study will evaluate the learning of the patient and his autonomy during a pen self-injection guided by a nurse.
