There are about 62 clinical studies being (or have been) conducted in Guadeloupe. 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.
The timing of renal replacement therapy (RRT) in the context of severe acute kidney injury (AKI) is one the most debated issues in critical care medicine. The Artificial Kidney Initiation in Kidney Injury (AKIKI) was the first large prospective multicenter randomized trial published on this topic. This study (published in the New England Journal of Medicine, July 2017) showed no significant difference between an early and delayed RRT initiation strategy in term of mortality. Nearly 50% of patients escaped RRT in the delayed strategy and this strategy was associated with less catheter-related infections and faster renal function recovery. Two (serum urea concentration >40 mmol/l and oliguria/anuria for more than 72 hours) of the 5 criteria which mandated RRT in the delayed strategy are still open to debate since they have never been shown to put patient at danger. To go further into our investigation of RRT criteria, the investigators designed a study that would compare the "delayed strategy" used in AKIKI that can now be considered as "standard" with another in which RRT is delayed for a longer period in the absence of a life-threatening complication (such as hyperkalemia or severe overload pulmonary edema).
The aim of this proposal is to evaluate the causal relationship between Zika virus (ZIKV) infections in pregnancy and congenital malformations. The study will estimate the absolute and relative risks of congenital malformations and other adverse outcomes of pregnancy among women who become infected with ZIKV during pregnancy compared to uninfected pregnant women, also leading to further validation of the Congenital Zika Syndrome.
Chlordecone is known to induce liver damage in rat and mice but no data exists in human being. However chlordecone was used until 1993 in French West Indies for banana fields, it is important to test what damage can be induced now, for patients exposed. We should consider chlordecone as a potential cofactor of liver fibrosis. So we have chosen to compare two populations of chronic hepatitis B, C or alcoholic, with cirrhosis or without fibrosis due to active hepatitis, who had been exposed to chlordecone.
Despite important advances in the current understanding of sickle cell vaso-occlusion, the basis of its control and prevention remain partially unknown. The primary purpose is to test the hypothesis of a control of the sickle cell vaso-cocclusive (VOC) process by the anti band 3 antibodies by assessing the level of these antibodies in the steady state and during the crises in SCA patients. To assess the relationship between the level of band 3 antibodies, the oxidation status, the expression of microparticles and the hemorheological alterations of the sickle red cells (SS RBs), the severity of VOC.
Type 2 diabetes is a major problem of public health in the French West Indies, with an estimated prevalence of 8%, twice more than in France. In Guadeloupe, according to the statistical data of hospital morbidity in 2004, 2643 hospital stays were diagnosed with diabetes. These cases mainly concerned woman (62%) and the elderly, from 45 to 74 years old (67%). The main objective of this research is to describe the insulin protocol used in Guadeloupe for treated type 2 diabetes patients and their characteristics: - The duration of the type 2 diabetes - Time elapsing between the diagnosis and the treatment by insulin - Where the follow up care took place - Existence of complications Secondary objectives were to describe the link between the HbA1c rate and the insulin therapy protocol. And also to present the main inconveniences expressed by patients and their degree of autonomy.
The purpose of this study is to compare the efficiency of conversion to IUI and IVF in patients with a poor ovarian response to stimulation
Approximately 50 to 60% of ICU patients are subjected to invasive mechanical ventilation-through a tracheal tube. Extubation consists of a key moment for the patient on the road to recovery (1). The extubation failure, is a major disease event. The incidence of extubation failure vary between studies between 10% and 20% of ventilated patients over 48 hours, it is therefore a significant risk including at the individual level. Ultimately, it is observed higher mortality for patients with unsuccessful extubation and this independently of their overall severity (2,3). Among the complications associated with extubation failure observed the occurrence of nosocomial pneumonia. Large-scale epidemiological data, covering nearly half of French ICUs found a risk of nosocomial pneumonia multiplied by a factor of 3 in case of extubation failure. Observing this strong association between nosocomial pneumonia and extubation failure does not presage a causal link. In all cases the onset of pneumonia probably involved in the morbidity and mortality of patients undergoing a failed extubation(4). Prevention of inhalation may limit congestion and bronchial and lung infection, and thereby reduce the risk of extubation failure. Indeed, the primary pathophysiologic mechanism responsible for nosocomial bronchopulmonary infection is inhalation of oropharyngeal and digestive secretions (5). This risk of inhalation during intubation motivates the implementation of fasting prior to general anesthesia for elective surgery patients. Indeed, it is recommended to respect a 6-hour fast for solids and 2 hours for liquid (water, fruit juices without pulp, tea or coffee without milk) in this situation (9). Although the situations are very different from the context of programmed anesthesia and extubation followed by a possible emergency reintubation on failure of extubation in the context of resuscitation, fasting appears as a potential means of limit the inhalation during the period of risk posed extubation and reintubation eventual resuscitation. Nevertheless, it is doubtful of the effectiveness of the single fasting to ensure gastric emptiness during the period of extubation. Indeed, a very large proportion of patients presents the delayed gastric emptying causing prolonged gastric fluid stasis. (10). Fasting and aspiration of gastric contents through a stomach tube has not, to our knowledge, never been rigorously evaluated in the ICU extubation. Moreover, the setting of fasting patients is likely to induce significant side effects first and foremost, a charge extra care for paramedics. The other major effect is the calorie deficit induced potential source of infectious complications and a delay in extubation.
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 project aims at developing and structuring a network of clinicians, pathologists, and scientists, from the "Grand Ouest" area, most of them already involved in prostate cancer management and research. Patients treated by radical prostatectomy will be recruited within the ReSCaP network of clinicians, with centralized database and standardized bio-resource collection, including prostate and adipose tissue samples. Seven clinical centers will participate to the network, 6 recruiting mainly Caucasian patients, and 1 from the French West Indies recruiting mainly African Caribbean patients. After 18 months, 1000 patients will be included. The main goal is to study the relationships between adipose tissue/lipids and prostate cancer aggressiveness. In fact, adipose tissue is likely to be involved in cancer progression at many levels: abdominal obesity has been associated with aggressive disease, and poly-unsaturated fatty acids (PUFAs), as well as cytokines produced by adipocytes (adipokines) have an impact on cancer cells growth and migration in vitro. Moreover, adipose tissue is the preferential site of storage of persistent organic pollutants with estrogenic properties, which could impact cancer progression. The study will analyze the association between adipose tissue (distant from the prostate) composition and cancer aggressiveness. Among the 1000 patients, 100 aggressive tumors will be selected according to the d'Amico criteria (Gleason score 8 or more and/or pT3 tumors). They will be matched with 100 potentially indolent prostate cancers (Gleason 6 or less, and PSA less than 10, and pT2 stage on the surgical specimen). These 200 adipose tissue samples will be analyzed for 1/ the lipid profile, including the fatty acid composition, particularly PUFAs, that reflects past dietary fat intake, 2/ adipokine expression, and 3/ tissue concentrations of persistent organic pollutants belonging to the class of organochlorine pesticides with hormone-like activity.
