Filter by:This study was aimed to conduct a 3-year perspective study to observe the immunological effect of one-dose mumps-containing vaccine, monitor the incidence of mumps in vaccinated population aged 3-7 years，and provide basis for adjusting MMR immunization strategy in Jiangsu province, China.
This study is part of a larger prospective cohort study (JOKA), designed to study the incidence and etiological spectrum of febrile illness occurring during a travel to the tropics, as well as clinical course, care, treatment and outcome of these febrile illness episodes. Its objective is to evaluate the clinical use of malaria rapid diagnostic tests (RDT) by travelers or their peers during travel, as a decision aid for the management of febrile illness in the tropics. If the study demonstrates that malaria can be ruled out safely by travelers themselves using a RDT, a combination of self/peer testing with SBET may become an alternative to antimalarial chemoprophylaxis in travel medicine.

Filter paper blood spots and paired serology are used in addition to routine post-travel evaluation, to study the incidence and etiological spectrum of febrile illness occurring during travel to the tropics. The study will yield valuable and prospective data of incidence rate, the clinical and etiological spectrum, clinical course and outcome of febrile illness during (and post-)travel in a prospective cohorts of travelers. This knowledge may lead to better pre-travel advice.
Levels of PCT (a marker of bacterial infection) are highest during sepsis: in fact, PCT is normally produced by the C cells in the thyroid gland. PCT was initially studied by Assicot1 for distinguishing between bacterial meningitis and viral meningitis. The CALC-I gene codes for PCT. In the absence of infection, the extrathyroid mRNA expression of the CALC-I gene is repressed, and expression is restricted to neuroendocrine thyroid and pulmonary cells. Infection induces the ubiquitous expression of the CALC-I gene. PCT is not transformed into calcitonin in parenchymatous tissues. In a context of sepsis, the whole body acts as a neuroendocrine gland. Sepsis upregulates PCT mRNA expression much more than that of other cytokines. PCT is used in critical care departments as a diagnostic marker, a guide to treatment (antibiotics are withdrawn if the level falls) and a prognostic marker. There are few data on the diagnostic use of PCT in an internal medicine department. The available studies yielded contradictory results and only one prospective study has been performed . The objective was to study PCT in non-infectious, inflammatory pathologies and to establish whether PCT could distinguish infections from other inflammatory pathologies in patients in an internal medicine department. In a ROC curve analysis, a PCT threshold of 0.35 µmol/l gave the greatest specificity (88%) and sensitivity (72%). Other studies have been performed but featured small sample sizes and a retrospective design. Of the various studies performed in internal medicine departments, none included patients presenting with a suspected bacterial infection (according to the clinician's interpretation) and lacking information on their bacterial status. In fact, these diagnoses are a core component of hospitalisation in internal medicine departments for fever or inflammatory syndrome. The investigators intend to include all patients, including those lacking information on their microbiological status).
Emergent and infectious diseases are a public health priority on Reunion Island. Amongst public health threats, the infection due to Coxiella burnetii (Q fever) seems to have appeared on Reunion island in 2007 with two hospitalised confirmed cases (one death) and one probable case with a goat farmer. According to the investigator, the diffusion of C. burnetti is more ancient and such diagnosis have been made in the last 30 years with 80 positive serologies identified between 2005 and 2011. Considering the high epidemic power of this disease, its often silent clinical expression and its life-threatening condition, the principal investigator wishes to perform a sero-epidemiological study in order to establish or to reject the risk of emergence of Q fever in Reunion island. The study will be performed on pregnant women because Q fever is responsible for particular complications during pregnancy and because the number of pregnancy followed on Reunion island is stable from one year to the other. The pregnant women population presenting the same exposure criteria as the general population, this population will be used to extrapolate to the general population of the island.
Based on the basic data of all patients foreseen for a local hyperthermia in the participating centers the failure rate (of the Celsius TCS Hyperthermia System) and the complication rate (injury to the patients) will be recorded.
This phase II trial studies how well obinutuzumab and lenalidomide work in treating patients with previously untreated stage II-IV grade 1-3a follicular lymphoma. Immunotherapy with obinutuzumab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as lenalidomide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving obinutuzumab and lenalidomide may work better in treating patients with previously untreated follicular lymphoma.
A point-of-care laboratory (POC) was set at North Hospital, Marseille, France for the diagnosis in less than two hours of traveller's fever caused by known pathogens, close to the reception of Emergency service. In this instance 30% of patients have no etiological diagnosis after the POC traveller's fever tests . The objective of this study is to implement a new diagnosis strategy relying on the hypothesis that a rectal swab would improve the etiological diagnosis of traveller's fever of at least 10%.
In patients with peritoneal metastases of colorectal cancer could be a radical removal of all tumor foci a significantly improved survival compared to a sole systemic chemotherapy are additionally achieved by a hyperthermic intraoperative chemotherapy (HIPEC).
The investigator will study the possibility of in situ heating of the liquid containing the chemotherapy, so as to avoid the need for an external pumping system with its complexity, and its associated risks and costs. The use of a heating cable (prototype hereinafter called Thermowire, made by the company EFS, which is in charge of its development) was patented and tested in pigs in two studies that included 15 animals altogether (in 7 of which the heating cable was used). The aim of the first study was the purely safety aspects, while the efficacy to obtain hyperthermia, the quality and the homogeneity of the hyperthermia and its effect on the tissue penetration of the chemotherapy were evaluated in a second study. The results obtained justify transfer to use in humans in the context of a clinical trial so as to obtain CE certification.
