Start date: May 21, 2021
Phase: N/A
Study type: Interventional

Hepatocellular carcinoma treated by laparotomy or laparoscopic Multicenter prospective, open, superiority, controlled, randomized, clinical trial The primary objective of the study will be to demonstrate the superiority of the laparoscopic approach over the open approach in reducing postoperative morbidity in HCC patients. Postoperative morbidity will be assessed using the Comprehensive Complication Index (CCI) within 90 days postoperatively or at any time during hospitalization

NCT ID: NCT04791696 Completed - Clinical trials for Corneal Transplant Rejection

Risk Factors for Human Corneal Graft Failure : a Monocentric Retrospective Observational Cohort

Start date: April 1, 2020
Phase:
Study type: Observational

Keratoplasty is one of the most common grafts and penetrating keratoplasty is still the technique most used in the world, ahead of lamellar grafts, and is estimated to represent 70% of the total. Graft rejection is still the main cause of failure of this type of surgery, to the extent that nearly a third of all patients will in some way be affected by rejection in due course. Numerous risk factors for rejection have been identified, whether related to the donor, the recipient, or the surgical procedure itself. In addition, many of the studies performed have used univariate analysis only, and yet there is a strong case for multivariate analysis, given the wide range of factors that need to be examined. This study seeks to analyze the rejection rates and the survival of penetrating keratoplasty for a group of patients from Montpellier Hospital (France).

NCT ID: NCT04791644 Recruiting - Lynch Syndrome Clinical Trials

Faecal Microbiota Characterization in Lynch Syndrome (LS) Patients With or Without Colorectal Neoplasia

Microbiote
Start date: April 20, 2021
Phase:
Study type: Observational [Patient Registry]

Colorectal cancer (CRC) is the second cause of cancer-related death in western countries. CRC prevention and screening are major public health issues. Better knowledge of colorectal carcinogenesis could lead to better prevention. Gut microbiota (GM) is a complex community of bacteria, fungi, protozoa, viruses and bacteriophages which live in a symbiotic and epigenetic relationship with the host. GM can promote either digestive health or CRC through inflammatory and proliferative effects. Lynch syndrome (LS) is the most common familial CRC syndrome with a lifetime CRC risk of 52% in women and 69% in men. The risk of CRC depends upon type of altered mismatch-repair gene and environmental factors (diet, exercise, obesity, tobacco and alcohol intake, etc.). Regular surveillance including annual or biannual colonoscopy is recommended in LS patients. Chemoprevention has the potential to represent a cost-effective intervention in these high-risk patients and could allow a delay in colonoscopy surveillance. Regular low dose aspirin use is associated with a 20 to 30% reduction in the risk of sporadic colonic adenomas and CRC. The real benefit of aspirin is still to be consolidated. AAS-Lynch trial is an ongoing prospective multicenter (n=37), double-blind, placebo-controlled, randomized clinical trial, designed to investigate whether daily aspirin, at a dose of 100 or 300 mg compared with placebo, would decrease the occurrence or recurrence of colorectal adenomas in LS patients. The primary endpoint is the number of patients with at least one adenoma detected by chromo-endoscopy 48 months after initial colon clearance. At randomization and at the end of study, stool collection, blood collection, quality of life questionnaire, validated food frequency questionnaire (SU-VI-MAX2) and physical activity questionnaire are performed. The ongoing AAS-Lynch study allow accessing to a unique fecal collection in very well characterized LS patients including a comprehensive dietary evaluation at high risk for colorectal neoplasia and planned colonoscopy surveillance during a 48 months follow-up, exposed or not exposed to chronic low dose aspirin. The expertise of the scientific consortium with state of the art microbiota analysis, the comprehensive collection of data and the prospective design of the study will allow the evaluation of the true role of gut microbiota in CRC carcinogenesis.

NCT ID: NCT04791488 Recruiting - Clinical trials for Decompression Sickness

Impact of Hyperoxia and Involvement of the Immune System in Diving Accident

OXYDIVE
Start date: March 30, 2022
Phase: N/A
Study type: Interventional

The impact of oxygen therapy in many pathologies has been subject of recent work, arguing both favourable and harmful effects. Consequently, one can wonder about the influence of hyperoxic gas mixture during diving on the genesis of decompression sickness, but also about the systematic application of normobaric and hyperbaric oxygen in case of proven decompression sickness. In mammals, normoxic concentrations have been redefined at 20-100 mbars at the extracellular level and below 10 mbars in the mitochondria. Under hyperbaric conditions, most of the oxygen being dissolved in blood plasma, a state of hyperoxia is established which escapes the usual delivery and regulation system represented by red blood cells. The results of our team's previous work suggest a specific effect of diving on the levels of circulating mitochondrial DNA (mtDNA), suggesting cellular destruction linked to hyperoxia/hyperbaria. In fact, our studies, carried out on both animals and human divers, have shown that diving accident leads to an increase in mtDNA levels and an immune reaction through the mobilisation of leukocytes. The main objective of this study is to compare the influence of oxygen partial pressure levels on the evolution of clinical and biological variables during hyperbaric oxygen therapy sessions in healthy versus injured divers.

NCT ID: NCT04791462 Completed - Osteoarthritis Clinical Trials

COVID-19 in Osteoarthritis Patients

Start date: March 10, 2021
Phase:
Study type: Observational

While the coronavirus pandemic has spread rapidly around the world, it has generated a considerable degree of fear, concern and anxiety among the population in general and among certain groups in particular, such as older persons. Initial findings from studies in China indicated the presence of moderate to severe psychological impact in a significant proportion of individuals and an increased prevalence of post-traumatic stress symptoms. It should also be noted that other types of symptoms, such as anxiety and depression, appeared to persist over time and to a greater extent. Osteoarthritis can develop in any joint, but most often affects the knees, hands and hips. People with osteoarthritis are often older and sometimes more frail than the general population. The main recommendations for non-drug treatment of osteoarthritis include education, physical activity and structured exercise programmes with or without weight reduction. Due to the confinement associated with COVID-19, many patients have had to stop exercise/physical activity and postpone prosthetic surgery. Apart from the context of delay in surgery, there is little data available on the impact of the pandemic on people with arthritis. Several questions are therefore still pending concerning the impact of the pandemic on these patients. The investigators hypothesise that the following therapeutic modalities have been disrupted during this period: access to care, scheduling of prosthetic surgery, consumption of painkillers or NSAIDs, recourse to physical activities, recourse to physiotherapy sessions, weight changes, level of pain.... Our objective is to evaluate the physical, social, psychological and behavioural consequences of the COVID-19 pandemic in a cohort of osteoarthritis patients.

NCT ID: NCT04791280 Recruiting - Systemic Sclerosis Clinical Trials

Study of the Intestinal Microbiota of Patients With Systemic Sclerosis

SCLEROMICROBIO
Start date: March 31, 2021
Phase:
Study type: Observational

The term gut microbiota describes the entire intestinal microbial communities. Studies have established the important role played by the gut microbiome in modulating vital functions of the healthy host. The physiological effects of the microbiota for the host are, for the most part, beneficial. In several pathologies, an imbalance in the composition of the microbiota has been demonstrated. Systemic sclerosis is an autoimmune, disorder of the connective tissue, characterized by vascular lesions, immunological abnormalities, and fibrosis of skin and internal organs As in many inflammatory diseases, there are painful digestive manifestations in systemic scleroderma that affect up to 90% of patients. The exact pathophysiology of the digestive involvement in systemic sclerosis is uncertain. The digestive manifestations of systemic sclerosis are frequent and can affect the entire digestive system. However, there are few studies of the intestinal microbiota in this disease, which seems to be part of the same continuum of diseases with abnormalities of innate immunity. By analogy with chronic inflammatory bowel diseases, particularly Crohn's disease, we have raised the question of the existence of dysbiosis during scleroderma which could lead to episodes of acute, severe and recurrent inflammation of the peritoneum under the influence of triggering factors. The long-term prospects would be to look for ways to prevent attacks or to treat them more rapidly and effectively by using therapeutic targets in the intestinal microbiota. The study population will be seen in the usual care setting, identically to all patients with systemic sclerosis treated in the department. In case of an inflammatory disease outbreak, and depending on its severity, the patient will be seen again in consultation or hospitalized. Appropriate complementary examinations (biology, imaging, endoscopy) will be carried out and the treatment adapted.

NCT ID: NCT04791241 Completed - Clinical trials for Acute Respiratory Failure

A Check-list Including Lung Ultrasound for ED Patients With ARF

CHECKIRA-COVID
Start date: March 3, 2021
Phase: N/A
Study type: Interventional

The aim of the study is to evaluate if a check-list including lung ultrasonography can help to identify the etiology of the acute respiratory failure of patients managed at the emergency room. Adult patients admitted to the emergency room for acute respiratory failure will be offered the study. The emergency physician will perform a systematic examination using a checklist, including pulmonary embolism prediction scores, structured clinical examination and lung ultrasound, in order to establish a diagnostic hypothesis. A diagnostic hypothesis will be made after completion of the checklist. The emergency physician can perform additional examinations and treatment after completion of the checklist. The final diagnosis will be checked by an adjudication committee which will have all the documents established during the emergency room consultation and any hospitalization following this hospitalization. The main outcome will be the concordance rate between the diagnosis after the check-list and the final diagnosis.

NCT ID: NCT04791189 Not yet recruiting - Clinical trials for Juvenile Idiopathic Arthritis

Survey on the Expectations of Adolescents With Juvenile Idiopathic Arthritis (JIA) Regarding Knowledge and Communication With Health Care Professionals in the Field of Sexual Health, and Their Parents' Views on the Subject. (SNAPS-JIA)

SNAPS-JIA
Start date: May 2021
Phase:
Study type: Observational

Sexual health is a legitimate area to explore in the care of these patients, as it has such an impact on quality of life. However, addressing sexual health in a situation of chronic disease confronts the double societal taboo of disease and sexuality. Health professionals are uncomfortable because they are not trained to talk about the subject, especially in the presence of parents and with a teenager they have watched grow up. In this context, a needs survey among juvenile idiopathic arthritis (JIA) patients and the point of view of their parents in the field of sexual health seems necessary. Main objective: To determine the expectations of adolescents (aged 10-19 years) with juvenile idiopathic arthritis regarding knowledge and communication with health care professionals in the field of sexual health.

NCT ID: NCT04791163 Completed - Clinical trials for Lower Limb Amputation Above Knee (Injury)

Above-knee Socket Evaluation : Sub-ischial vs Ischial Containment

P20-EMBSUBI
Start date: April 15, 2021
Phase: N/A
Study type: Interventional

Socket is key to provide comfort and function to lower limb amputees. A new socket, the sub-ischial socket, will be compared to "traditional" ischial containment sockets, based on comfort self-evaluation, and locomotor capacities.

NCT ID: NCT04791150 Recruiting - Arthritis Clinical Trials

Rheumatologic Adverse Events and Cancer Immunotherapy

Start date: May 7, 2021
Phase: N/A
Study type: Interventional

In this study, every patient with cancer who is going to be treated by immunotherapy will fill in a form. In this form, we try to determine if he presents rheumatologic complications of his immunotherapy. If the patient answers yes to one question on the form, the patient will be see in rheumatologic consultation to explore his clinical signs. The number of patients referred in consultation thanks to this questionnaire will be compared to the number of patients who would have been spontaneously referred by the oncologist. The aim of this questionnaire is to optimise the management of rheumatological effects secondary to immunotherapy.
