There are about 36633 clinical studies being (or have been) conducted in France. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Microbial communities are key components of human environment. Consequently, human gut microbiome have been extensively studied providing a better understanding of the relations between bacterial populations and host physiology. However, a typical analysis tends to elude the complexity of the mixes in term of species, strains, as well as extra-chromosomal DNA molecules such as and phages. MetaKids project aims at bringing, at an unprecedented resolution, a new view of those populations and the internal relationships during human gut establishment, a crucial step with long-term impacts on host health. This project relies on the ability of Meta3C, a newly technique developed in the lab, to identify the bacterial host genomes of the different phages the investigators will detect thanks to the physical collision these molecules experience. Given the role that human gut phages may play in shaping the development of host microbiomes, their potential for application is of great interest.
Some patients with dry eye may have severe disabling neuropathic pain. They describe spontaneous pain, dysesthesia, hyperalgesia or even allodynia. It is classical to note an important discordance between the high intensity of the symptoms and the poverty of the clinical signs. These pains are often unrecognized and therefore often not sufficiently treated. A significant impact on patient's quality of life may occur. The concept of ocular neuropathic pain being relatively recent, few studies have focused on the subject at present. Our study aims to shed light on these pains in patients consulting for dry eyes at the Ophthalmological Foundation A. de Rothschild. The objective of our study is to describe precisely the characteristics of neuropathic eye pain and the visual, general and psychological repercussions in these patients.
Current curative treatment of digestive peritoneal carcinomatosis consists of complete cytoreduction surgery associated with intraperitoneal chemotherapy. This treatment has important limits: a high morbimortality and the impossibility of repeating the sessions. The majority of patients are therefore treated with systemic chemotherapy, which despite its progress, remains palliative. Pressurized Intraperitoneal aerosol chemotherapy (PIPAC) has many advantages: under laparoscopy, low morbidity, good intratumoral penetration of cytotoxics, possibility of repeating the sessions and low financial cost. Therefore, the investigator propose a phase 1 study, in colorectal and stomach cancer, with oxaliplatin doses escalation in Pressurized Intraperitoneal aerosol chemotherapy. It would allow a better tumor response, with potentially few risks and thus improve survival in patients with digestive peritoneal carcinoses, increasing access to cytoreductive surgery.
The objective of the study is to generate safety and performance data for the 4Tech TriCinch Coil System in symptomatic patients suffering from significant functional tricuspid regurgitation with annular dilatation. The TriCinch Coil System is a percutaneous catheter-based medical device for tricuspid valve repair.
In rheumatoid arthritis (RA) the clinical response to anti-TNFα is related to an increase in the number or in the function of Treg lymphocytes in the peripheral blood of patients. This observation suggests the central role of Tregs in homeostasis of the immune response during RA. In the literature the Tregs frequency and phenotype in the peripheral blood are well documented, however the analyses done on the Tregs in inflamed environment are still fragmentary or disparate. In this project Tregs phenotype as well as expression of several transcripts will be analysed in order to better characterize the Treg cell subsets within the synovial fluid. Moreover, the local inflammatory cytokines (TNF, IL-6 and IL-1) may affect both the phenotype and the suppressive function of these Tregs and a comparison between peripheral and tissue Tregs will allow us to better understand the cause of functional loss. Outcomes: Primary outcome: Identification and characterization of the Tregs subpopulation present in the synovial fluid for RA patients suffering an episode of acute arthritis. Secondary outcomes: compare the phenotypic and expression profile of the Tregs present in the synovial fluid with the Tregs present in the peripheral blood of RA patients suffering from an episode of acute arthritis.
Segmental overgrowth disorders are rare conditions characterised by abnormal growth which is usually asymmetric and confined to discrete parts of the body. We and others have identified mosaic activating mutations in the p110α catalytic subunit of phosphatidylinositol-3-kinase (PI3K; encoded by the PIK3CA gene) in a subset of overgrowth disorders. The PI3K-AKT-mTOR is a critical signalling pathway, which regulates cellular growth, proliferation and survival. Activating mutations in PIK3CA lead to increased activation of the PI3K-AKT-mTORC1 axis, which in turn promotes excessive growth in affected tissue. The PIK3CA-related overgrowth spectrum is wide, and depends upon the timing of the founder mutation in embryogenesis, and potentially upon the exact mutation. Clinical presentation ranges from isolated enlargement of a digit, to extensive overgrowth of limbs, abdomen and in some cases the brain, and may be accompanied by vascular or lymphatic malformations. Associated morbidity can be profound, with functional impairment, debilitating haemorrhages and thromboses, coupled with neurological sequelae and, in some cases, death. At present, serial debulking surgery is the only available therapeutic option. The identification of gain-of-function mutations in PI3K has raised the possibility of treatment with drugs that inhibit PIK3CA (the p110 alpha catalytic subunit of PI3K). Taselisib is a selective inhibitor of class I PI3Ks and has direct inhibitory activity of the p110α isoform with a Kiapp value of 0.29 nmol/l.
This was a phase II, randomized, placebo-controlled, double-blind study to evaluate the efficacy and safety of Semorinemab in participants with prodromal to mild Alzheimer's disease. An optional 96-week open-label extension period was available to participants who completed the double-blind treatment period and who, in the judgment of the investigator, would potentially benefit from open-label Semorinemab treatment.
The dorsolateral prefrontal cortex (DLPFC) plays a key part in emotional processing and regulation. Emotions continually influence other cognitive functions such as attentional resources .Emotions also influence a subject's automatic physiological responses . Transcranial direct current stimulation (tDCS) is an innovative neuro-modulation treatment, often used in major depression. Various studies have shown that it is possible to modulate emotional processing in healthy subjects, however the impact of this modulation on attentional resources and physiological responses has not been studied. Also, the mechanisms of action of the tDCS on emotional processing are still unclear. It is necessary to explore the modulation of the DLPFC in healthy subjects in order to better understand the network and mechanisms at stake in the processes. Thus, investigators plan to study the modulation of the DLPFC (left and right) by tDCS (anode, cathode and placebo) on the processing of emotions and the impact on attentional resources, and physiological responses.
This study will evaluate the safety and efficacy of relamorelin compared to placebo in participants with diabetic gastroparesis. Participants will report daily severity scores of their diabetic gastroparesis symptoms.
A majority of people undergoing rehabilitation following a stroke have a deficit of the dorsal flexors of the foot. The implementation of rehabilitation techniques in accordance with the recommendations of learned societies is not sufficient to compensate for this deficit. Also Kinesio Taping's method of Dr. Kenzo Kase has caught our attention by its action on muscle, joint, circulatory and pain functions. The use of taping would increase the duration of stimulation of the muscles of the dorsiflexors of the foot which would facilitate the motor recovery. Data from the literature do not support the conclusion that taping is effective, but no studies evaluating the efficacy of this technique in the foot-lift deficiency of the hemiplegic patient have been found. The investigators hypothesize that the use of taping in conjunction with common rehabilitation for hemiplegic patients following a stroke improves the stimulation of the muscles of the dorsiflexors of the foot with a positive impact on the walking.
