Glaucoma is one of the leading causes of blindness in the world. The key to prevention of visual loss from glaucoma is early detection of the disease or its progression and timely treatment. The proposed study will investigate the role of various tests in improving detection of disease progression in advanced glaucoma. Evaluation of the peripheral field of vision (visual field examination) remains the current standard for detection of progression in glaucoma. However, there is a lot of variability or inconsistency in eyes with advanced glaucoma, which could make it difficult to detect worsening of glaucoma with visual fields. The optic nerve demonstrates significant damage in such eyes and hence oftentimes repeat imaging of the optic nerve head is not helpful for detection of change. Therefore, imaging of the central retina (the innermost sensitive tissue lining the inside of the eye), called macula, has been proposed to supplant imaging of the nerve in eyes with severe glaucoma. The macula aids in detailed central vision. Since the macular retinal neural cells are the last ones to be affected in glaucoma, measurement of macular retinal thickness could provide significant information with regard to the course of glaucoma. In the proposed study, glaucoma patients will be tested and followed with various measurements done with newer versions of optical coherence tomography (OCT) imaging and visual field machines. The patients will undergo repeat imaging and visual field testing every 6 months over the course of 5 years. Rates of change will be estimated. We will explore if changes in various outcome measures derived from imaging are correlated with the corresponding visual field changes in glaucoma, and whether the former can be used as an alternative method for detecting simultaneous or subsequent glaucoma progression. The hypothesis for this proposed research is that macular OCT parameters are valid structural measures that can be used especially in advanced disease to follow the course of glaucoma.
The aim of this study is to determine the activity, to assess the safety and tolerance of BKM120 in adult patients with recurrent or metastatic head and neck cancer progressive under platin and cetuximab-based chemotherapy.
The purpose of this study is to find out more about some of the unusual chemicals (called oligosaccharides) that can occur naturally as a result of processes in the body. Researchers want to look at how these chemicals change with time and how they change between different patients with MPSIVA. These unusual chemicals were recently discovered in the urine from patients with MPSIVA. The investigators would like to study these chemicals before a specific enzyme replacement therapy is used. If the investigators understand how these chemicals change, the investigators may be able to use them to monitor this condition in the near future as well as help doctors know whether certain therapies work well in their patients.
Bronchopulmonary infection is the most common and serious complication in the evolutionary course of cystic fibrosis (CF). Administration of antibiotics adapted to infecting pathogens is one of the key issues for its management. However, more than half of patients with CF have chronic respiratory infections for which infectious agent remains unknown leading to empirical antibiotic therapies that are not adapted to the causative agents. Recently, new technologies have been applied for the description and characterization of microbial agents in CF patients including molecular biology techniques that allowed us to detect and to identify new and/or emerging pathogens. Moreover, more sophisticated molecular techniques such as pyrosequencing and PCR amplification and cloning lead us to demonstrate the huge microbial diversity associated with chronic bronchopulmonary infections in this population. Otherwise, a metagenomic approach revealed the extraordinary complexity of the respiratory flora in these patients and, somewhat unexpected, abundance of anaerobes, viruses, and bacteriophages. In addition, it has been shown that some antibiotics commonly used in clinical practice for the treatment of respiratory infections were able to induce these bacteriophages, suggesting the existence of lateral gene transfer by transduction. The human microbiome is the set of microbial communities associated with the human body and represents all living microorganisms in the body. Its role in the immunity development has recently been demonstrated suggesting that changes in this ecosystem play a critical role in evolution of several human diseases. For example, in obesity it has been shown that there is a relationship between the intestinal human microbiota and nutritional and metabolic status of the hosts and specific alterations of these intestinal microbiota may represent a metagenomic signature of this disease. Evolution of the respiratory microbiota in patients with cystic fibrosis, whose nutritional status is often impaired (chronic malnutrition due to disorder of digestive absorption) and receiving regular antibiotic treatments remains unknown to date. Characterization of this ecosystem and its role is a critical step to understand the evolutionary course of the disease. The main objective of this seminal study is to describe and to characterize the respiratory microbiota from sputum samples obtained from a limited number of selected patients with CF from 5 regional care centers (CRCM) from South of France (Mucomed network) (2 patients per center : 6 adults and 4 children), with similar clinical, microbiological and functional status before and after a cure of antibiotics. Different microbiological tools will be used including axenic culture systems, co-culture on amoebae in order to to isolate and to identify the microbial communities. Identification of bacteria will be done using MALDI-TOF mass spectrometry and/or molecular techniques. Moreover, 16S rRNA PCR amplification followed by cloning and sequencing of PCR products from the same sputum sample will be carried out to identify and to compare the bacterial species identified using molecular methods. In a second step, once the respiratory microbiota was characterized, it will be interesting to develop a dedicated microarray that will allow to detect all the bacteria identified in the first stage of the project and to assess its relevance on a larger cohort of patients with CF by studying the correlation between the respiratory microbiota and clinical status of patients according to the prescribed antibiotic treatments. This study will open new clinical perspectives and will help us to determine the potential role of antibiotics on the microbiota evolution during treatment according to regional health care practices. This will contribute to better understand the role of the microbiota in the evolution of these chronic respiratory infections. It could be the first step for innovative therapeutic strategies, taking into account the balance of complex microbial flora and possibly evolving according to antibiotic therapies. It could also form part of a larger preventive strategy against transmission of specific pathogens in CF.
The purpose of this study is to determine whether Tcelna (imilecleucel-T, autologous T-Cell Immunotherapy) is effective in the treatment of secondary progressive multiple sclerosis (SPMS).
The purpose of this study is to examine whether an magnetic resonance imaging (MRI) -guided treatment strategy based on a predefined treatment algorithm can prevent progression of erosive joint damage, increase remission rate and improve functional level in the short and long term in patients with rheumatoid arthritis (RA).
The need for new technologies and devices in the field of neurosurgery is well established. In April 2013, FDA cleared NeuroBlate™ System, minimally invasive robotic laser thermotherapy tool. It employs a pulsed surgical laser to deliver targeted energy to abnormal brain tissue caused by tumors and lesions. This post-marketing, multi-center study will include patients with metastatic tumors who failed stereotactic radiosurgery and are already scheduled for NeuroBlate procedure. The study will collect clinical outcome, Quality of Life (QoL) and, where feasible, healthcare utilization data for publication.
Alzheimers disease (AD) is the most common course of cognitive decline and thereby the course of more than half of all cases of dementia. A proper AD diagnosis is rested on a number of examinations and tests, which combined can make AD diagnosis likely. But no single test or examination can unambiguous determine whether the patient has AD or not. Comparatively no examination or test can with accuracy predict whether a healthy person or a person with only mild cognitive (MCI)impairment in time will evolve AD. Quantitative Electroencephalography (qEEG), cerebrospinal fluid (CSF) biomarkers, linear CT analyses and Timed Up and Go - Dual Task (TUG-DT) are relatively inexpensive and and widely available diagnostic methods, which have the potential to diagnose AD at an early stage in a reliable accurate way. But they also have the potential to predict which patients diagnosed with MCI have particular risk of developing dementia. The purpose of the study is to investigate the relations between qEEG, CSF biomarkers, CT analyses and TUG-DT outcome and clinical features in healthy persons as well as patients with MCI and AD Furthermore to investigate whether qEEG or CSF biomarkers can predict which patients with MCI will in time evolve AD.
The purpose of this study is to assess whether in a population of patients with advanced colorectal cancer for which no known effective therapy is available, measuring the spontaneous evolution of tumoral metabolic progression index by serial FGD PET-CT and Diffusion MRI can show that tumor growth rate is related to the patient's outcome, and that serial FDG PET-CT and Diffusion MRI are able to measure it.
