There are about 26 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.
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.
The primary aim of this study is to estimate the frequency and to characterize clinically atypical parkinsonism in the French West Indies and Guyana.
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 diagnosis and the follow-up of the patients reached of SLA is centralized, since a few years, at the the Caribbean Reference center of the rare neurological diseases (CERCA labélisé in 2006) in Martinique and at the Unity of coverage of the neuromuscular Diseases, SLA and the rare neurological diseases (create in 2010) in Guadeloupe. Several phenotypic characteristics seemed to us to take out again data collected during the follow-up of the patients (26 in Guadeloupe, since the creation of the unity) in particular patients' high proportion of exceptionally long evolution (more than 10 years). Besides, we diagnosed several cases (10 cases in Guadeloupe since 2000) of association SLA- Parkinsonien Syndrome. This association, considered as exceptional could establish a particular phenotypic entity which we would like to describe. We are interested also originally geographical of the patients, with the hypothesis that he could exist in the Antilles one or several geographical isolates of the disease allowing to lead a étiologique investigation in search of a possible genetic or environmental cause.
Hereditary (familial) amyloidosis arising from the misfolding of a mutated or variant transthyretin, is the most frequent form of amyloid cardiomyopathy in the Caribbean basin. Affected organs invariably harbor extracellular amyloid deposits in the myocardium. Circulating or pre-fibrillar amyloidogenic proteins are implicated in the disruption of cell function. Our aim is to demonstrate that transthyretin mediated amyloid disease alter the mitochondrial function of cardiac cells.
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.
The purpose of this study is to provide a surveillance system to monitor changes in the rate of mother to child HIV transmission and preventive practices in France and especially to identify the occurrence of toxicity in children exposed perinatally to antiretroviral drugs.
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.
Postural changes are commonly used as therapeutic maneuver to enhance or reduce cerebral perfusion. For instance, in acute stroke, the patient can be positioned in head down tilt position so as to increase perfusion of cerebral tissues perfusion. In During stroke and in hypertensive patients and during stroke, varying degrees a various loss of cerebral autoregulation is loss are usually observed. The aim of this study is to assess cerebral perfusion with ASL perfusion in human subjects in different conditions: healthy, hypertensive and stroke.
