It was difficult to obtain clinical benefits through traditional chemotherapy and radiotherapy for the patients who have recurrence or metastasis tumor even though they have received first-line chemotherapy or combined radiotherapy before, but failed.The aim of this study was to evaluate the safety and efficacy of apatinib, an anti-angiogenesis drug, in the treatment of patients with advanced esophageal squamous cell carcinoma who had recurrence or metastasis after radical resection
Phase II Clinical Trial to Assess the dose-response and Efficacy of Umbilical Cord-derived Mesenchymal Stromal Cells (MSCs) in Severe Renal Systemic Lupus Erythematosus (SLE).
Of the 50,000 prostate cancers that occur each year in France, more than half will benefit from curative radiotherapy, alone or in combination with hormone therapy from 6 months to 3 years depending on the stage of the disease. At present, there are few ways to predict the response to this irradiation. Evaluating the early response of tumor tissue to irradiation could predict the final response to treatment. It is difficult to offer biopsies during treatment for reasons of patient comfort. This is why this study consists in analysing transcriptomic and protein responses (immunohistochemistry) to irradiation on ex vivo prostate explants. These explants will be irradiated after culture and the transcriptional and immunohistochemical changes analysed before and after irradiation to determine an early tumor tissue response profile to irradiation.
Vitreous fluid, containing 95% water, fills the space behind the lens. Its gelatinous consistency is due to the presence of hyaluronic acid, mucopolysaccharide and collagen fibers. With age, the collagen aggregates into parallel bundles, bound by cross links, leaving the pockets of liquid in the glass body. This redistribution is referred to as syneresis, which is found in 90% older than 40 years. After liquefaction, the vitreous enters the retroviral space and separates the posterior hyaloid membrane from the retina. When separating from the optical disk it forms an annular formation (Weiss ring) in front of the optical disc. These agglomerated collagen bundles (opacities) disperse the photons of light and are perceived by the patients as a "gray silhouette-like artifact". Two major interventions for these symptoms include Nd: YAG laser vitreolysis and vitrectomy. The less invasive method Nd: YAG laser increases the temperature of the opacity thus vaporizing them to smaller fragments that are easier to sediment onto the bottom of the vitreous cavity thereby relieving the symptoms.
Nephrology care continues to progress and recommendations are now focused on delaying as much as possible the need for renal replacement therapy ("intent-to-defer"strategy). Protein restriction is a valuable tool for stabilizing chronic kidney disease (CKD) and retarding the need for renal replacement therapy, but the best diet to be prescribed is still matter of discussion. This study is aimed at identifying implementation strategies for nutritional management of advanced CKD.
The aim of this multicenter, investigator-initiated, prospective, randomized, open-label, non-inferiority study is to evaluate a prednisone prescribing strategy, guided by eosinophil blood count compared to the standard (systematic) administration of corticosteroids, in patients with COPD exacerbation requiring ventilatory support. Patients fulfilling inclusion criteria and consenting to participate in the study, will be randomized through a random table generated electronically, to eosinophil-guided group or to control group. In the eosinophil-guided group, prednisone (1mg/kg/day for up to 5 days or during the hospital stay if less than 5 days) is administered only if the eosinophil count is >2%. If blood eosinophil count is ≤2%, no corticosteroids are given. In the control group: a treatment based on prednisone at a daily dose of 1 mg/kg will be routinely administered for a maximum of 5 days, or during the hospital stay, if it is less than 5 days. Corticosteroid treatment is taken in the morning in patients with NIV, and through the gastric tube in intubated patients. The hypothesis tested is a non-inferiority of the "eosinophil-guided strategy" compared to the standard strategy, with less exposure to corticosteroids. The primary endpoint is the proportion of unventilated patients at day 6 which is set to 50% in the control group. A pre-specified difference <10% would be a non-inferiority margin. Secondary endpoints are: Number of ICU days alive without ventilatory support within 28 days after recruitment, length of stay in intensive care Unit, the intubation rate in patients initially under NIV, Mortality in the ICU, Hospital mortality. Safety: New onset of diabetes or worsening of diabetes requiring the start or the increase in insulin therapy, Upper gastrointestinal bleeding (2 g drop of Hb requiring blood transfusion or fibroscopy), Uncontrolled hypertensive crisis requiring the introduction of new antihypertensives, ICU-acquired neuromyopathy, Nosocomial infection, Relapse rate / recurrence defined respectively by the rate of a new hospital consultation and/or admission in the week or the month following index hospitalization. Sample size calculation: In a non-inferiority study, with an incidence of the event (no ventilation at D6) of 50% in the control group ( with 10% of acceptable difference for non-inferiority), a power of 80% and alpha error <0.05, it would take 86 patients per arm by anticipating 2% of lost sight.
This study collects information about the safety and effect of portal vein stenting in gastrointestinal cancer patients with portal vein stenosis. This study may help researchers learn how long the portal vein stays open and free from blockage and the effects of portal vein stenting on patients' overall well-being.
Recent numbers display a 85% survival-rate in children after a very harmful disease such as cancer. However, the survivors still experience mild to severe side effects of the primary disease or treatment. A long time follow-up in the University Hospital of Ghent in children with cancer displays important long term side effects such as: reduced muscle strength; reduced endurance capacity; reduced exercise tolerance; fatigue; disturbed body composition with increased risk for obesity and/or diabetes and osteoporosis; and neuropathic damage and myopathy. These physical complaints have a significant impact on the activities and participation in daily living. The purpose of this interventional study is to create a rehabilitation program for children after acute cancer treatment. The goal is to minimalize the previous described long term side effects of the disease. The current study should allow us to determine the effects of the intervention at the level of functioning, activities and participation. In addition, we account for the environment and personal factors as described by the International Classification of Functioning, disability and health (ICF-criteria). The study population consists of children between 8 and 11 years and adolescents of 12 to 21 years old. All participants receive a multidisciplinary treatment for 4 months, guided by a team which includes: oncologist, rehabilitation doctor, physical therapist, dietitian, psychologist, and occupational therapist. At the beginning of the multidisciplinary program, the participants receive psychoeducation, diet advice, tips for participation, fatigue, and psychological well-being. In general, the rehabilitation program focusses on reintegration at school and leisure activity. After the first assessment, an individually adjusted physical program consisting of strength and endurance training will be made. This physical program will be executed 3 times a week, 2 times guided by a physical therapist at the University Hospital or at a private practice, and ones a week by themselves at home recorded by an activity tracker. Follow-up is foreseen on monthly basis. Participants will undergo assessment 3 times: 1) baseline (T0); 2) after 4 months treatment (T1); 3) after 1 year follow-up (T2). The purpose of this program is to encourage patients at risk for increasing their healthy habits, exercise and participation in order to decrease long-term (side) effects.
The purpose of this study is to test a pediatric narcolepsy patient reported outcomes tool to assess pediatric narcolepsy symptoms and their effect on daily functioning and quality of life. The goal is to develop a clinical survey that can improve the care of pediatric narcolepsy.
The role of the immune system in Idiopathic Nephrotic Syndrome (INS) of Minimal Change Disease (MCD), Mesangial proliferative Glomerulonephritis (MesGN) or Focal and Segmental Glomerulosclerosis (FSGS) has been widely investigated. However, among immune cell populations, a major player in disease pathogenesis was never found. The efficacy of B cell depleting therapy with anti-CD20 monoclonal antibodies suggests that B lymphocytes may play the pivotal role. Preliminary data suggest that memory B cells may be the responsible of the Nephrotic Syndrome (NS) relapse after rituximab treatment in in children with Steroid Dependent Nephrotic Syndrome (SDNS) or Frequently-Relapsin gnephrotic Syndrome (FRNS), enforcing the role of the B cell lineage in the disease pathogenesis. NS is a severe glomerular disease affecting more frequently children and young adult. It is characterized by edema, heavy proteinuria and hypoalbuminemia, the clinical counterpart of the alteration of the selective glomerular permeability barrier. Despite extensive investigation, the mechanism and the immune cell population responsible for the disruption of glomerular filtration barrier and, consequently, of the development of proteinuria is still not clearly defined. However, the efficacy of the different immunosuppressive approaches including prednisone and anti-CD20 antibodies in the treatment of NS strongly suggests a central role of the immune system, in particular the role of B cells in the pathogenesis SDNS. Recent evidence indicates that, after B cell depletion, the delayed reconstitution of the switched memory B cells in children with SDNS was significantly and independently protective against relapse. These results suggest that recovery of switched memory B-cells after anti-CD20 therapies could be a useful predictor of subsequent relapse of the NS in SDNS and FRNS patients, and that memory B-cells may play a role in the pathogenesis of SDNS or FRNS in children. The main aim of the present study is to determine whether reconstitution of different B-cell subpopulations can predict relapse after treatment with B-cell depleting antibodies in adult with NS, and whether specific B- or T-cell anomalies (as well as dysregulation of other circulating immune cell subsets) may play a role in the disease pathogenesis of SDNS and FRNS
