There are about 103 clinical studies being (or have been) conducted in Martinique. 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.
In postoperative pleuro-pulmonary surgery, the monitoring of the appearance of complications is guided, depending on the centres, by the systematic daily performance or, in the event of a call point, by chest x-ray at the patient's bed until the drains are ablative. This repeated performance of radiographs results in irradiation of patients but also of medical staff and a significant cost. In the thoracic study, ultrasound imaging is a fast, cost-effective, non-irradiating solution that can be performed at the patient's bedside. It could guide the performance of chest x-ray, limit their number, with increased clinical relevance.
Rheumatoid arthritis is a genuine systemic disease associated with diffuse interstitial pneumopathy and bronchial disorders. According to the literature review, the prevalence of PID on thoracic CT scan is one-third of patients. Diffuse interstitial pneumopathy is responsible for a significant morbidity and mortality, is currently under-diagnosed and its treatment is poorly codified. The lung seems to have a central role in the genesis of rheumatoid arthritis. It also appears that some subtypes of anti citrullinated peptide antibodies are preferentially present in the lungs. The hypothesis behind our project is that one or more subtypes of anti citrullinated peptide antibodies with a preferential tropism for the lung would attack the parenchyma and pulmonary airways. Currently, there are no data on interstitial pneumopathy in black and Afro-Caribbean subjects with rheumatoid arthritis.
Retrospective observational comparative and multicentric study of the microenvironment of HPV-induced head and neck cancers, with comparison between West Indies and Metropolitan populations, and therapeutic implications. This assessment is carried out by in situ multiparametric study with multiple immunofluorescence staining for cluster of differentiation 3, cluster of differentiation 4, cluster of differentiation 8, PROGRAMMED DEATH-1, PROGRAMMED DEATH-L1, PROGRAMMED DEATH-L2, cytokeratin and cluster of differentiation 68 and automated reading. HPV genotypes will be characterized. Learning these techniques will allow me to promote them in West Indies on my way back, and they may be applicable to other HPV-induced cancers.
In 2004 an ASAS for the Assessment of SpondyloArthritis International Society decided to work to improve the criteria for classification of spondyloarthropathies to allow for early diagnosis, Nuclear magnetic resonance imaging (MRI). This approach led to the publication in 2009 of the classification criteria for spondylarthritis, in particular axial spondyloarthritis, as well as a proposal to modify the classification of criteria defined by Mr. Amor (AMOR) and European Spondylarthropathy Study Group (ESSG) criteria, taking into account the potential abnormalities visible in Magnetic Resonance Imaging Nuclear (MRI). The performance (specificity, sensitivity, positive and negative predictive values) of the ASAS criteria was then prospectively tested on a sample of the Metropolitan Caucasian population and this systematic study allowed to estimate the performance of the ASAS criteria in the usual framework Of the French Liberal Rheumatology Consultation. Note that this approach is exposed to a criticism of "circular" approach, indeed the expert who is the gold standard for the diagnosis, uses more or less consciously "criteria" based on the presence of such and such sign, then checks in this selected population the diagnostic validity of these signs. However, no data on the performance of ASAS criteria are available in populations of African descent.
Data extraction from bacteriological laboratory of Martinique University hospital to determine the frequency and the distribution of nosocomial infections due to Achromobacter xylosoxidans (ACHX), an emerging multi-resistant environmental bacteria. The specific tropical environment and climatic conditions in Martinique may favor ACHX development and the investigators suppose that this new opportunistic pathogen can represent a danger for hospitalized patients. The aim of our study is to describe the most affected population and try to identify the main environmental sources of contamination.
In France, suicide behaviours are a major public health concern that triggered the creation in 2013 of a National Observatory of Suicide. In continental France, the "Algos" protocol was found to be effective for the prevention of suicide attempts reiterations. This protocol is based on a procedure that keeps telephone and postal contacts with the suicide attempter and allows, via an algorithm, to assess the risk of suicide attempt recurrence, in order to intervene if necessary. Nevertheless, Algos does not involve primary care health practitioners, who could add a substantial additional efficacy, especially if they intervene downstream and in supplement to Algos. In addition, this kind of protocol has never been evaluated in the French overseas territories.
pulmonary arterial hypertension (PAH) has been reported with a prevalence of approximately 30% in adult sickle cell disease (SCD) patients, with an increased mortality in SCD patients with PAH, compared with those without PAH. The identification of several hemolysis biomarkers such as lactate dehydrogenase, bilirubin, reticulocytes or hemoglobin level, has clearly documented a link between hemolysis and PAH. However, other physiopathological mechanisms may be involved to explain PAH in these patients, such as pulmonary thromboembolism, pulmonary fibrosis or left heart diastolic and / or systolic dysfunction. The investigators suggest studying HTAP in patient's presenting the most frequent both drepanocytic syndromes, SS and SC and homogeneous in their medical coverage and the association between HTAP risk and specific SCD complications.
The frequency of cardiac amyloidosis among patients presenting with a so-called left ventricular hypertrophy remains unknown. This problem is especially relevant in the Caribbean's, where an amyloidosis-prone mutation of transthyretin gene might be frequent.
In oncology a number of supportive care therapies are proposed to patients. This study will identify the different therapies and prioritize these therapies from the patients' perspectives. This study will provide a framework for optimizing supportive care strategies and identifying those therapies that need to be validated by clinical trials.
Alzheimer's disease (AD) is a neurodegenerative disease leading to one of the most common forms of dementia in humans and memory disorder is one of the first symptoms that lead to diagnosis.
