Heavy menstrual bleeding (HMB) affects approximately one in four women and imposes considerable social, emotional, physical and economic burdens. Despite various treatment options available, endometrial ablation (Novasure) has emerged as a promising solution, with documented efficacy and high patient satisfaction rates. In the context of peri- and postoperative pain, research has reported that patients experienced less pain during the Novasure endometrial ablation procedure in comparison with two other systems. Moreover, postoperative pain rates were lower in patients treated with Novasure compared to another endometrial ablation device (ThermaChoice system). Nonetheless, it remains unclear how patients in detail experience the Novasure treatment. It is not clear which factors contribute to either a positive or a negative experience. Moreover, it is unknown if women wish more education before the procedure in order to feel well prepared for the procedure and possible post-procedural symptoms. Therefore, we want to investigate how women with heavy menstrual bleeding experience education about endometrial ablation (Novasure) treatment, the procedure itself and short-term care after treatment. In this randomized-controlled pilot study, the aim is : 1. To determine if educational videos that show experiences from women with HMB that were treated with Novasure endometrial ablation affect preoperative anxiety. 2. To assess if educational videos have an effect on preoperative need for information 3. To explore Novasure pre-, peri- and postoperative patient experiences 4. To define positive and negative factors related to Novasure endometrial ablation 5. To gain insight in factors that could improve patient satisfaction before, during and after Novasure endometrial ablation and to evaluate the educational videos.
Over the last decade many scientific articles have been published on motor learning in neurological and geriatric rehabilitation. To make the available findings comprehendible and clear for physiotherapists, a card set and website have been developed. The aim of this prospective study is to evaluate the use and experiences of the card set and website designed to aid the physiotherapist in decision making with regards to motor learning. The following research question is central to this evaluation: How are the developed card set and website used and experienced by physiotherapists in primary care during the treatment of patients with neurological or geriatric conditions?
Randomized placebo-controlled double-blind cross-over N=1 trial in adult male and female patients with UACR >20 mg/g (2.26 mg/mmol) with type 2 diabetes treated in primary or secondary healthcare. The goal of this clinical trial is to determine the individual response to the SGLT2 inhibitor dapagliflozin in urine albumin-to-creatinine ratio (UACR). Secondary objectives are to determine the individual response to dapagliflozin in systolic blood pressure, body weight, eGFR, and fasting plasma glucose. Participants will collect all study data in the comfort of their own environments: - First-morning void urine samples - Capillary blood samples - Blood pressure - Body weight Participants will be randomly assigned to a cross-over study consisting of two periods of 1-week treatment with dapagliflozin 10 mg/day and two periods of 1-week treatment with placebo in random order with a 1-week wash-out period between every treatment period to avoid cross-over effects.
Rationale: Currently baseline brain MRI (magnetic resonance imaging) with extended follow-up of pineal cysts is systematically performed in all new retinoblastoma (Rb) patients, because children with hereditary retinoblastoma have an increased risk of primitive neuroectodermal tumors (PNET) that are histopathologically identical to the retinal tumors (1). The prevalence of developing a PNET in combination with unilateral or bilateral hereditary Rb is 5-15% (2). Treatment is difficult and the prognosis is poor as only few survivors are reported. Only patients with small asymptomatic PNETs (<15 mm) are potentially curable. Objective: The main objective of this prospective multicenter study is to evaluate the current strategy of baseline MRI screening of the brain in newly diagnosed retinoblastoma patients, with extended follow-up of selected patients with simple and complicated pineal cysts. Study design: The investigators propose a prospective cohort study (part of a larger multicenter study) to investigate the diagnostic accuracy and survival of baseline MRI screening of the pineal gland in new patients with retinoblastoma, with extended follow-up of selected patients with pineal cysts for early detection of pineoblastoma. Study population: Within the European Retinoblastoma Imaging Collaboration (ERIC) about 150 new retinoblastoma patients are diagnosed every year. About 10 percent of all new retinoblastoma patients will be diagnosed at the VUmc. According to our sample size calculations the investigators will need 334 Rb patients. Main study parameters/endpoints: The primary endpoint of the study is pineoblastoma or supra- / parasellar PNET on MRI (index test). Because a gold standard will not be available, tumor cells in cerebrospinal fluid, histopathological confirmation, clinical disease progression during follow-up, and/or follow-up MRI diagnostics will be used as a composite reference standard in case of a positive index test and clinical diagnosis of pineoblastoma or supra- / parasellar PNET within one year of the last MRI will be used as a composite reference standard in case of a negative index test.
The goal of this study is to measure concentrations of the drug tacrolimus in both whole blood and within T lymphocytes. It will also learn on the correlation between the concentration in T lymphocytes and the effects of the drug. The main questions are: (i) What is the ratio between the tacrolimus concentration within T lymphocytes and in whole blood?; (ii) What is the correlation between tacrolimus concentrations and the effects of the drug? Participants will: - Receive standard clinical care; - Undergo two extra venipunctures for the collection of blood.
The goal of this randomized controlled trial is to test a brief psychological intervention that focusses on acceptance of stress in a student population. The main questions it aims to answer are: - Does this brief acceptance intervention increase the well-being of students in the short term? - By which mechanisms does this effect occur? - What are moderating factors of this effect? Half of the participants follow a one-hour intervention, which includes - psychoeducation and metaphors about stress and how acceptance can help to deal with it - experiential exercises - mindfulness meditation - mindfulness homework practice Students that receive the intervention will be compared to students that merely received psychoeducation about stress and acceptance to see if the intervention lead to larger increases in well-being.
This study has been previously registered with the National Trial Registry (NTR6267) that has been cancelled. The registered trial has been automatically transferred to a new "Landelijk Trial Register", which does not contain all correct information on the current study and where no corrections can be made. Hence, the current study has been registered again with ClinicalTrials.gov. The goal of this clinical trial is to study the effectiveness of an internet-based self-management intervention in adult patients with fibromyalgia. A randomized controlled trial (RCT) will be performed, in which 70 participants will be randomized to either the self-management intervention or a waitlist control condition (patients in the waitlist condition will receive the intervention after the intervention ends in the intervention group, i.e., after 6 months). The primary effect constitutes of the difference in change in pain coping between patients in the intervention and control condition from baseline to post-intervention. As secondary outcomes, a number of other psychological and physical outcome measures will be assessed (e.g., health-related quality of life, well-being, pain impact on daily life, pain cognitions). Also, cost-effectiveness of the intervention and the quality of the therapeutic relationship will be measured.
Venous thromboembolic Events (VTEs) are common in lung cancer patients with an incidence of >15%, requiring anticoagulant treatment or prophylaxis. Although direct acting oral anticoagulants (DOACs) are the agents of first choice due to ease and patient friendliness, these drugs are often avoided in cancer patients due to suspected pharmacokinetic drug-drug interactions with oncolytic drugs. Sotorasib is the first KRASG12C inhibitor that has been approved by the US [FDA] and EU [EMA] for the treatment of adult patients with KRAS G12C-mutated locally advanced or metastatic NSCLC. Sotorasib has a potential to cause CYP3A-mediated drug-drug interactions due to induction of CYP3A and inhibition of P-GP. Rivaroxaban is the most frequently prescribed DOAC in the Netherlands. As rivaroxaban is a substrate for this enzyme and efflux pump, sotorasib may increase or decrease the exposure to rivaroxaban and, thus, impact its benefit-to-risk ratio. To enable safe combination of sotorasib and rivaroxaban, it is pivotal to investigate the magnitude of the pharmacokinetic interaction between these drugs.
Rationale: In COVID19 single-targeted immunomodulation, mostly via an IL-6 receptor blocker, was used by a one-size fits all non-targeted approach. In future pandemics the same might occur. However, for individual patients, this might not yield optimal treatment. Objectives: This project aims to identify a way to individualize and target immunomodulation, using COVID19 as a testcase for the future. - Identify immunological pathways which are associated with outcome in C-ARDS. - Test whether an individualized biomarker-based approach has an effect on outcome and costs when using single-target immunomodulation in C-ARDS(Tocilizumab, Anakinra, etc.). - Explore whether other immunological pathways were present in patients with C-ARDS which could have been intervened with medication which is already available and has been described in ARDS or similar diseases. Study type: Retrospective observational multicenter study in the Netherlands. Study population: Adult patients (≥ 18 years) hospitalized and admitted to the ICU with COVID-19 and acute respiratory distress syndrome (ARDS) (i.e., receiving invasive mechanical ventilation) will be included. Intervention (if applicable): Not applicable (retrospective study design). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Given the retrospective nature of the study, no burden, risks or benefits for the patient are associated with participation. The target population of this study is specific to hospitalized patients with COVID-19.
