Filter by:Pediatric Crohn's Disease is a life long disease , presenting early in life.As such , it is imperative to be able to evaluate the risk for more severe disease and poorer outcomes when making the decision which therapies to offer our patients. These decisions should be based according to longer-term disease outcomes, such as whether they prevent disease relapse or prolong remission [10-12]. However, for the most part, previous studies were not designed to yield predictive parameters that could allow a clinician to differentiate which patients are at a higher risk for relapse, or more likely to to have serious attacks or complications of the disease or therapy. The ability to predict these risks would impact dramatically the way CD patients are treated, allowing the clinician to tailor therapy, both type and intensity, to each patient's individual risk for relapse and outcomes.In the present first phase of the study , we will attempt to identify factors that predict relapse of the disease, focusing on the use of calprotectin at onset and after clinical remission, and on the use of anti-glycan antibodies, as well as disease severity, site and phenotype.
Observational, prospective (1 year follow up), multicenter, non-interventional open label study in order to assess the factors that predict onset of mood disorders episodes (depression, mania, hypomania and mixed) in stabilized patients with bipolar disorder I or II in Spain. Other objectives are 1. to describe the clinical course of illness in a cohort of patients with TB I or II: duration, severity, polarity and seasonality 2. to describe clinical and functional situation of patients during the different phases, evaluating prognostic meaning of subsyndromal symptoms 3. to evaluate the economical impact on health service of these patients (hospitalization, primary care, treatments…). Target population is ambulatory bipolar I and II patients, clinically stabilized for at least the two months prior to recruitment and who had at least one acute episode (depressive, manic, hypomanic or mixed) within the year prior to recruitment. The primary endpoint is the onset of mood disorders episodes (depression, mania, hypomania and mixed) during the follow-up period and evaluation of which factors predict onset of mood episodes
Sometimes, cancer comes back after it has been successfully treated—a situation called recurrent cancer. When recurrent cancer is suspected, the standard approach to diagnosis is to perform a combination of imaging tests, such as x-rays, ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and nuclear medicine scans. Sometimes, however, after performing these tests it still may not be clear whether or not the cancer has come back. Some studies have shown that a diagnostic imaging test called Positron Emission Tomography/Computed Tomography (PET/CT) may be helpful in the diagnosis of recurrent lung, breast, head and neck, ovarian or esophageal cancer or lymphoma. However, it is not clear if PET/CT can offer better results than standard approaches to diagnosis. This feasibility study is needed to determine how common it is for a diagnosis of recurrent cancer to be unclear even after standard diagnostic imaging tests have been completed. If the enrollment goal is reached (~60 patients enrolled in 18 months), a larger clinical trial is being planned to determine if PET/CT is helpful in making the diagnosis of recurrent cancer in situations where standard imaging tests have not been helpful. It is also expected that the results of this feasibility study will help to define exactly which patients should be enrolled in this larger clinical trial of PET/CT.
There is evidence to support the use of melatonin, a natural health product, as an additional treatment aid for cancer patients. This study is designed to see if the daily ingestion of 20 milligrams of melatonin for one year can lower the incidence of developing lung cancer recurrence and/or death. Only patients with a diagnosis of non small cell lung cancer who are eligible for surgical resection can participate in the trial. The study will also be assessing for changes in quality of life, pain, fatigue, anxiety, sleep, and depression amongst the participants.
The aim of the trial is to demonstrate that 100 mg of oral minocycline twice daily reduces the conversion of CIS to McDonald Criteria MS (McDMS) by an absolute 25% as compared to placebo, over a 6 month follow-up period (primary outcome). A key secondary outcome is to confirm that this early treatment benefit is maintained at two years.
A Finnish Breast Cancer Group Study (BREX 01-2004). A multicenter phase III open randomised trial of the efficacy of exercise in the prevention of long-term adverse effects of adjuvant treatments and breast cancer recurrences in women with primary breast cancer. The aim of the study is to investigate whether regular exercise training could reduce the long-term side effects of adjuvant treatments of primary breast cancer and improve quality of life and well being.
The aim of the study is to define preferential sites of tumour recurrence by observing tracer uptake in the tumour in sequential PET images with 18F-fluoromethylcholine (and perfusion MR, see also below). Changes in the intensity of the tracer uptake in the tumour during and after the course of radiotherapy will be correlated with the site of tumour recurrence as will be assessed by conventional MRI. In due time, these results must enable clinicians to change their therapeutic approach of high-grade glioma.
The PRET study aims at comparing two types of coils used in the endovascular treatment of intracranial aneurysms. The first type made of platinum has been used for more than 15 years. The other, referred to as hydrocoil, containing in addition to platinum a polymer layer that expands when in contact with blood, has been in use since 2002. The hypothesis of the PRET study is that the newer hydrocoil will be more effective and yet as safe as the older platinum coil.
Varenicline (Chantix) is a smoking cessation treatment that was approved in 2006 by the FDA for treatment of nicotine dependence and may be particularly beneficial in smokers with schizophrenia or bipolar disorder. Early experience with varenicline indicates that it will be effective for smoking cessation in schizophrenia and in addition, has the potential to be therapeutic for cognitive dysfunction in this population. In addition, more data is needed to evaluate the safety, tolerability and effectiveness of Varenicline in people with bipolar disorder. To assess this possibility, we will evaluate the safety and efficacy of 12 months of varenicline in schizophrenia or bipolar disorder patients who are able to quit smoking in the short term with this treatment. To do so, we will enroll 324 smokers with schizophrenia or bipolar disorder from 6 mental health clinics in Massachusetts, New Hampshire, Michigan and Minnesota into an open, 12-week smoking cessation program that includes varenicline added to weekly group cognitive behavioral therapy (CBT). Those who achieve at least 2 weeks of continuous abstinence during the last 2 weeks of the open intervention will be randomized to the relapse prevention phase: a 40-week, double blind, placebo-controlled trial of varenicline at the dose used to quit smoking added to a tapering CBT schedule. Participants will then discontinue study medications and behavioral treatment and enter a 3-month follow up phase.
Despite extensive medical treatment, surgical resection is required in approximately 70% of the patients at some time. However, recurrence of the disease after operation occurs in the majority of patients and is a serious limitation of surgical management. Therapeutic options to maintain postoperative clinical remission are urgently needed. Several drugs including mesalazine, antibiotics (metronidazole, ornidazole) and azathioprine or 6-mercaptopurine have been studied in the past. But the efficacy is very limited (mesalazine), overshadowed by intolerability during long-term therapy (metronidazole, ornidazole) or inconclusive (azathioprine or 6-mercaptopurine). Research demonstrating the absence of inflammation in patients with diverting ileostomy and the clinical benefit of a postoperative antibiotic therapy using metronidazole or ornidazole implicates a role of the resident bacterial flora in the postoperative relapse. Ciprofloxacin has a broad antibacterial spectrum. More interestingly it also suppresses E. coli strains, which can be found in high numbers in early and chronic ileal lesions of Crohn's disease patients Ciprofloxacin has demonstrated beneficial effects in the therapy of inflammatory bowel diseases, but the available data of the effectiveness of ciprofloxacin allow only a very limited judgement of the safety and tolerability of a 6 months therapy of ciprofloxacin. Therefore an exploratory multicenter prospective, placebo-controlled trial is planned to analyze the safety and tolerability of a 6 months therapy with ciprofloxacin compared to placebo in 40 patients (randomly assigned in a 1:1 ratio) undergoing ileocecal resection (or resection of parts of the colon). If this therapeutic regimen demonstrates tolerability, a second larger study improving the superiority of ciprofloxacin versus placebo can be initiated.
