There are about 36633 clinical studies being (or have been) conducted in France. 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 main aim of this study is to find out the safety, tolerability and pharmacokinetics (PK) of maribavir for the treatment of CMV infection in children and teenagers after HSCT or SOT and to identify the optimal dose of maribavir using a 200 milligrams (mg) adult tablet formulation or other formulation based on PK modeling. The participants will be treated with maribavir for 8 weeks. Participants need to visit their doctor during 12-week follow-up period.
Alpha-1 kinase (ALPK1) has been reported as a potential causative gene for ROSAH Syndrome. Genetic variants including T237M have been found in ROSAH Syndrome patients. Our in-house study has found that T237M mutation leads to hyperactivity of ALPK1, which may be the cause of the inflammatory syndromes found in ROSAH Syndrome patients. We hypothesize that T237M mutation ALPK1 cause ROSAH Syndrome and an ALPK1 inhibitor can be a potential therapy for treating this disease. To test our hypothesis, we designed an experiment in which ex vivo peripheral blood mononuclear cells (PBMCs) from ROSAH Syndrome patients will be exposed to a potent ALPK1 inhibitor (DF-003) or placebo. We expect to see downregulation of activated inflammatory genes, chemokine/cytokines and acute phase proteins in the ROSAH Syndrome patient samples that are exposed DF-003.
Urinary tract infections are very common in pediatrics. Urinary antibiotic prophylaxis is commonly used in children with malformative uropathies. Long-term, low-dose antibiotic prophylaxis with trimethoprim-sulfamethoxazole has been associated with a decrease in the number of urinary tract infections in susceptible children, but not systematically with a decrease in the risk of renal scarring (depending of uropathy stage). Long-term antibiotic prophylaxis has implications for the acquisition of antibiotic resistance. A child receiving antibiotic prophylaxis for urinary tract infection is around 6 times more likely to develop a multidrug-resistant infection. In the general population, the microbiota of children treated with curative antibiotics is less diverse in terms of species and strains. In addition, short-term compositional changes are observed between consecutive samples of children treated with antibiotics. The gut microbiota modulates the immune system, in particular via metabolites (SCFA, polysaccharide A) produced by bacteria that modify the expansion and function of regulatory T-cells. The disturbances of the intestinal microbiota play a role in the medium and long term on the acquisition of pathologies, such as atopy. The study authors wish to describe the intestinal microbiota of children with vesico-ureteral reflux treated long-term with trimethoprim-sulfamethoxazole and compared it those not receiving antibiotic prophylaxis and to healthy children.
The development of mobile applications ("mobile apps") is steadily increasing and appears to be a promising treatment method to help people change unwanted behaviors or maintain a regular relationship with the medical system. Mobile apps aimed at smoking cessation have been shown to be effective. However, if a treatment is not used regularly, it will not have the desired effect. The main objective of this study is to identify what makes a person decide to use a smoking cessation app and to do so regularly. The second objective is to determine what is necessary to achieve long-term change with a mobile app.
The risk of venous thromboembolism (VTE), which consists of deep vein thrombosis (DVT) and pulmonary embolism (PE), increases during pregnancy and most strikingly in the postpartum period (6 weeks after delivery). Extensive research efforts have led to the identification of many risk factors for VTE events. Examples of such factors include maternal characteristics (personal history of VTE, thrombophilia, obesity, race) and obstetrical characteristics (methods of delivery, pre-term delivery, growth retardation). These allow care providers to risk stratify women at the time of delivery into low, moderate and high-risk women, based on experts' opinion. Further, a risk score, which was recently developed and validated on English and Swedish populations, estimates the risk of postpartum VTE in individuals. Thromboprophylaxis (TPX) focuses on the use of short-term low-molecular-weight heparin (LMWH). LMWH is believed to reduce the risk of VTE by 50-70%, but the evidence is indirect, with a lack of large-scale randomized trial in the setting of the postpartum period. Further, LMWH is both inconvenient (subcutaneous injections) and possibly associated with haemorrhagic side effects. Alternative drugs do not exist, because direct oral anticoagulants (DOAC) and aspirin are not studied in this setting and because DOAC are contra-indicated in pregnancy and breastfeeding. Given the unclear balance of benefits and risks, current guidelines vary greatly in the proportion of women with recommended TPX. Gassmann et al. have recently demonstrated, among a cohort of parturients at the Geneva University Hospitals: a recommendation of postpartum TPX in 40.1% of women, with an estimated mean risk of postpartum VTE of 0.12%, according to the 2015 UK guidelines (RCOG), and a recommendation of postpartum TPX in 8.7% of women, with an estimated mean risk of postpartum VTE of 0.20%, according to the 2018 US guidance (ACOG).These low risks of VTE to trigger a recommendation of TPX use contrast with that of experts' opinions, which advocate for a threshold of VTE risk of 1-3% to recommend the use of TPX. Currently, all women delivering by C-section in Geneva receive TPX regardless of their VTE risk. This dramatic discrepancy of TPX guidance between guidelines, and between guidelines and individual experts, highlights the uncertainty in this setting. Womens' preferences would be critically important here, to guide a rationale and desired use of TPX. Quite surprisingly, such preferences have never been elicited, in spite of the very large number of births every year (5 and 4 million in Europe and the US, respectively). To inform prescription patterns of postpartum TPX, investigators propose to conduct this prospective study to elicit values and preferences of pregnant and postpartum women.
Proximal femur fractures (PFF) are a worldwide public health concern. A delay in the diagnosis and treatment worsens the prognosis. Inversion of grayscale is a tool available on most X-rays visualization software, and its use has been suggested to improve radiological diagnosis. The study aims to determine if using inverted grayscale radiography results in better diagnoses of PFF among medical students. Material and Methods. The investigators evaluated the detection of PFF by fifth-year medical students on a series of 30 pelvis X-rays. The series was composed of 20 X-rays with PFF and 10 X-rays without fracture. A first reading session was set up where X-rays were presented separately in conventional and inverted grayscale. A second session one month later showed both grayscale visualizations together (BIcontrast X-rays Analysis Method - BIXAM). X-rays' order of appearance was randomized. The investigators performed the same evaluation on senior orthopedic surgeons as a control. Finally, sensitivity, specificity, and accuracy were assessed for each method (conventional, inverted, and BIXAM) with the McNemar test. Subgroup analyses were performed on the fracture localization (femoral neck, trochanteric).
The aim of this study is to show the efficiency of a new infant formula containing fiber on the management of moderate to severe atopic dermatitis.
During weaning from mechanical ventilation, the shift from positive to negative pressure ventilation may be responsible for a cardiac dysfunction that can lead to the development of pulmonary oedema (weaning-induced pulmonary oedema, WIPO) and to the failure of spontaneous breathing trials. However, the incidence and risk factors for WIPO development are not well defined and have been investigated only by a few studies.
Managing patients with renal failure requires an understanding of the molecular mechanisms that lead to its occurrence (i.e. upstream of the disease), its worsening and its persistence (i.e. downstream), while also specifying the risk of worsening renal failure (risk stratification, intolerance to the treatment or complications (infectious, metabolic, cardiovascular, cancer…). Nephrogene 2.0 aims to study these different components of kidney, immune and solid organ transplantation (SOT)-related diseases.
