There are about 13332 clinical studies being (or have been) conducted in Netherlands. 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.
Rationale and objective: Based on the results of a pilot study, the objective of the present study is to evaluate whether buttermilk lower serum LDL cholesterol concentrations and can prevent the serum LDL cholesterol raising effects of eggs. Study Design: The study has a randomized placebo-controlled factorial 2x2 design. The total study duration is 14 weeks, consisting of a 2 weeks run-in period and a 12 weeks experimental period. Subjects will be stratified for age, gender and BMI over the experimental groups. Study population: One hundred and eight healthy male and female subjects, aged 18-70 years, with slightly elevated serum total cholesterol concentrations (5.5-8.0 mmol/l). Intervention: During the entire study period, volunteers are instructed to consume a diet according to the Dutch dietary guidelines (35 en% fat (10 en% saturated fat), 50-55 en% carbohydrates). During the two weeks run-in period all subjects will drink daily at lunch 100 mL skimmed milk. During the 12 weeks experimental period, a first group of subjects will continue drinking the skimmed milk (control group), while a second group will consume a low-fat buttermilk, a third group skimmed milk enriched with egg-yolk, and a fourth group egg-yolk incorporated into a low-fat buttermilk based beverage. The egg-yolk will be enriched in lutein. Whole egg consumption (others than provided by us) is not allowed during the entire study. Main study parameters/endpoints: Measurements will be performed during the run-in period (days 0, 11 and 14) and during the experimental period (days 56, 95 and 98). The main effects (egg-yolk and buttermilk consumption) will be calculated as the absolute differences between values obtained at the end of the experimental (average days 95 and 98) and run-in (average days 11 and 14) periods. The primary endpoint is the change in serum LDL cholesterol concentrations. Secondary endpoints are changes in serum total and HDL cholesterol, triacylglycerol, apoA-I, apoB and hsCRP concentrations.
The investigators hypothesize that certain mutations in the individual cancer genomes will predict response to Everolimus therapy. To identify possible genetic mutations that affect tumor response to Everolimus the investigators will obtain sequence analysis of tumors from all patients that will be treated with Everolimus in this study. Moreover, the investigators performed a systematic review of the currently available data to identify mutations that could be predictive for increased mTOR activity in cancer cells. These mutations have been described to lead to mTOR activation but their predictive value for response to Everolimus therapy remains unclear. The investigators will use the data generated in the investigators own prospective treatment study and the data from literature to select patients for entry into a second part of this trial. In this part the investigators want to test the hypothesis that selecting patients based on their specific genetic mutations increases the likelihood of response.
It is well known that metabolic responses to diet and drugs are affected by genetic and environmental factors. Still, a large part of differences in responses between individuals remains unexplained. To increase our understanding of individual differences, more and more attention is paid to the role of intestinal microbiota. Not only energy and glucose may be related to the microbiota, but also lipid metabolism. This is not surprising as lipid metabolism, glucose metabolism, and obesity are closely linked. There is substantial evidence from in particular animal studies that the gut microbiota is related to lipid and lipoprotein metabolism. However, there is less evidence to what extent modulation of the gut microbiota changes lipid and lipoprotein metabolism in humans.
The purpose of this study is to show the success of the AutoLog System in removing lipids to less than 10mg/dl in vivo. The Autolog registry has two objectives: 1. to determine the lipid removal capabilities of the Medtronic AutoLog System. 2. to obtain in vivo data on blood component removal and washing capabilities of the Medtronic AutoLog System.
This study will compare the efficacy, in terms of complete responses and overall survival, of inotuzumab ozogamicin versus investigator's choice of chemotherapy.
This was a multicenter, randomized, phase II study evaluating Everolimus or Pasireotide LAR alone or in combination in adult patients with advanced (unresectable or metastatic) neuroendocrine carcinoma of the lung and thymus
The primary goal of this study is to determine the neuroprotective qualities of long-term, in home, exercise therapy program in human PD patients. It is hypothesized that an exercise intervention might delay the onset of levo-dopa therapy (i.e. evidence for neuroprotection). The first part involves a pilot-study in which the feasibility of the intervention and outcome measures will be tested.
Persistent postsurgical abdominal pain (PPAP) is a very difficult to treat pain. This pain can persist for months or even years and significantly diminishes quality of life. The exact underlying cause for this pain persistence is still unclear, which makes its treatment still a challenge. The promising analgesic effects of Δ9-THC in previous research, plus the improved bioavailability of Namisol® in comparison with previous Δ9-THC substances form the basis of the present research proposal. The current study aims to investigate the analgesic efficacy of Namisol® as add-on analgesic during a long-term treatment (52 days) of persistent postsurgical abdominal pain.
Background An important part of individuals undergoing genetic counseling and/or testing for cancer experience psychosocial problems and worries during or after this process. Approximately 20% of these individuals experience serious problems, such as fear for cancer in themselves or their relatives, family communication problems, unresolved grief, problems in coping with the DNA-test-results, difficulties in choices with regard to DNA-testing, preventive surgeries, and concerns about insurance or work. Research shows that these problems are frequently undetected by the counselors. Within the limited available time of a counseling session, a lot of information should be given to the counselee. This information is mostly biomedical and provider driven. Therefore psychosocial issues can be underexposed. The use of a brief questionnaire, completed by the counselee prior to the counseling session, can serve as a tool for the counselor to screen and address the relevant psychosocial issues in a systematic manner. Therefore, in 2009-2010 the investigators have developed and validated the 'Signal-checklist' to identify relevant psychosocial problems frequently encountered in the cancer-genetics setting, and need for extra psychosocial services. This 'Signal-checklist' can serve as a tool in screening systematically for psychosocial issues, addressing these issues and directing appropriate referrals to extra psychosocial services. The Signal-Trial will be performed to evaluate the use and effectiveness of the checklist. Aim The aim of the trial is to evaluate the implementation of a short, self-developed cancer-genetics checklist; the 'Signal-checklist', as an aid in 1) facilitating communication on psychosocial issues during the genetic counseling session, 2) increasing counselors awareness of psychosocial problems of the counselee, and 3) improving the management of these psychosocial problems during and after the process of genetic counselling. Method This study is a collaboration between the family cancer clinics of the NKI-AVL and the UMCU. Individuals requesting genetic counseling for the high incidence of cancer in their family are invited to participate in the trial. Participants will be asked to complete the 'Signal checklist' prior to their counseling visit. Participants (N=264) will be randomly assigned to one of the two study arms. The intervention group will receive feed-back on the 'Signal-checklist', whereas the control group will not receive feed-back. Three weeks after the DNA-test disclosure session, participants will be asked to complete again the 'Signal-checklist' followed by a telephone call by their counselor. Again, the results of the 'Signal-checklist' will be available to the counselor for participants in the intervention group, but not for the control group. Both the genetic counseling session and telephone call will be audio taped. Furthermore, all participants will be asked to complete three questionnaires on the Internet (or by mail, if preferred); 1) before randomization (3 weeks prior to the counseling session), 2) three weeks after the counseling session, and 3) four months after the potential DNA-test result disclosure. These questionnaires include items on communication during genetic counseling, the need for professional psychosocial support, cancer worries, satisfaction with received care, and experiences with the use of the 'Signal-checklist'. The audio-tapes and completed questionnaires will be used to measure psychosocial problems of the counselees, the awareness of the counselors of these problems, and the management of these problems. Secondary analysis will be conducted to assess the need for extra psychosocial services, satisfaction with genetic counseling, feasibility of implementing the 'Signal-checklist' and decreasing psychosocial problems over time.
