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.
The goal of this cross over study is to investigate the effect of short term time restricted eating (TRE) on the innate immune system in patients with a history of myocardial infarction.
Rationale: An adrenal crisis is an acute life-threatening event which may occur in patients with adrenal insufficiency. The initial emergency treatment consists of an intramuscular injection with 100 mg hydrocortisone administered by the patient or a bystander. The injection should be administered immediately. Although it is considered life-saving, it is not very patient-friendly, because of the several steps required for reconstitution, the intramuscular injection, the frequent presence of needle phobia, and pain at the injection site. Inhalation of predniso(lo)ne could be a more patient-friendly alternative. Objective: This study investigates the pharmacokinetics of nebulized prednisolone in two different dosages. Study design: Single-center, open-label study Study population: Healthy participants aged 18-75 years. Intervention (if applicable): Healthy volunteers receive a lower dose of nebulized prednisolone (46.75 mg).After a wash-out period of at least one week, each volunteer receives a higher dose of nebulized prednisolone (93.5 mg). Main study parameters/endpoints: To establish the time from nebulizing to maximum prednisolone concentration in serum and the area under the curve of prednisolone. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Participants are exposed to a single supraphysiological dose of glucocorticoids on two separate occasions. The risk of SAE is very limited. There is a small risk of an AE during blood sampling. If it is demonstrated that therapeutic plasma concentrations of prednisolone can be reached by nebulizing prednisolone, we intend to use the pharmacokinetic data to design and perform a clinical study with a dry-powder micronized prednisone inhalation. This would represent a novel and promising alternative treatment for an adrenal crisis. Patients with adrenal insufficiency could then be offered a much more patient-friendly and reliable alternative for intramuscular hydrocortisone injection.
Introduction: Complications of robotic-assisted total knee arthroplasty (TKA) seem to be rare and consist mainly of infections or fractures. In the Reinier Haga Orthopedisch Centrum (RHOC), postoperative bleeding is experienced to be a complication that often occurs, mainly at the tibial wounds of the registration pins used in robotic-assisted TKA. This often results in longer hospital stay and might interfere with the current fast track knee surgery by a delayed discharge. To overcome this complication, nowadays bone plugs are used in the two drill-holes. Currently, it is unknown whether these bone plugs reduces the incidence of postoperative bleeding. Objective: To evaluate the incidence of postoperative bleeding in patients that underwent a robotic-assisted TKA and received bone plugs in the two drill-holes in the tibia, compared to patients that underwent the same operation but did not receive bone plugs. Study design: Retrospective, inventory study Study population: All patients that underwent a robotic-assisted TKA in the RHOC from December 2020 till October 2022. Intervention: In the past, some patients that underwent a robotic-assisted TKA received a bone plug in the two tibial drill-holes. This bone is collected from the excess bone that is removed during the operation. Main study parameters/endpoints: Incidence of postoperative bleeding in both groups.
The purpose of this study is to assess the whole-body biodistribution and tumour uptake of 89Zr-S095012 in participants with solid tumours treated with S095012 (PD-L1x4-1BB bispecific antibody)
The goal of this observational pilot study is to evaluate the feasibility and accuracy of tracked ultrasound registration on patients undergoing abdominal cancer navigation surgery. The main research question is: Could tracked ultrasound be applied as an alternative to standard CBCT scanning in surgical navigation? Participants will undergo tracked ultrasound measurements of the pelvic bone on the operating room after patient anesthesia and before surgical incision.
In this study we aim to develop an automatic pelvic artery segmentation algorithm, which is required for future clinical implementation of US registration for surgical navigation. Various registration methods will be evaluated with the data of this study to obtain most optimal results. If automatic segmentation and registration is successful, the final accuracy of the developed US registration method for tumor tracking should be evaluated in future studies in patients eligible for surgical navigation. Eventually, we aim to replace the CBCT-scan with an automatic tracked US registration pipeline for a more efficient and accurate registration procedure, which could improve the applicability and accuracy of surgical navigation and patient outcomes.
Management of the neck in Wang cT1-T2N0 nasal vestibule carcinoma (NVC) has been an ongoing point of discussion. As the disease is rare publications are scarce and published regional recurrence rates vary widely between 0% up to 23%. In general, literature recommends adequate radiological neck staging followed by a watchful waiting policy, as overall regional recurrence rates are low (5-10%). However, according to recent findings, a subset of patients with large or voluminous cT1-T2N0 NVC is deemed at high risk of nodal involvement (20-40% regional recurrence) but receive no elective treatment, although it is well known that presence of nodal metastases impacts the prognosis of head and neck cancer (HNC) dramatically. Whereas elective neck dissection may be too aggressive, sentinel node biopsy (SNB) has been proven a reliable and safe alternative to bridge the gap between imaging and neck dissection. SNB is currently routinely employed in most HNC centres in the Netherlands and is considered state of the art care, but its application in HNC is limited to oral cavity carcinoma and squamous cell carcinoma of the skin. Following the observation of increased risk of (occult) nodal metastases and regional recurrence in bulky tumors, the sentinel node procedure seems ideally suited for cT1-T2N0 NVC patients. Its superficial tumor localization is easily accessible for peritumoral Tc-99m-nanocolloid-ICG tracer injection. The purpose of this prospective registration study is to document the clinical introduction of the sentinel node procedure for bulky nasal vestibule carcinoma in our centre by protocol, and to identify and address possible unexpected difficulties specific for this tumor site. Ultimately, the goal will be routine and wide implementation of SNB in the NVC subgroup known to be at risk of nodal involvement, as a means to improve regional disease staging and control. Objective: To prospectively document the introduction of the sentinel node procedure for bulky cT1-T2N0 nasal vestibule carcinoma in patients at risk of nodal involvement. Study design: Single centre prospective registration study. To be extended with a second centre. Study population: Patients with Wang cT1-T2N0 squamous cell carcinoma of the nasal vestibule, with tumor diameter ≥1.5 cm and/or tumor volume ≥1.5 cm3, with a WHO performance score of 2 or lower and no history of previous surgery or radiotherapy of the neck. Interventions: 1. Subcutaneous peritumoral radioactive tracer injection followed by lymphoscintigraphy and Single Photon Emission Computed Tomography (SPECT) imaging for sentinel lymph node visualization. 2. Surgical sentinel node biopsy and histopathological examination of harvested nodes following the abovementioned imaging. Main study parameters/endpoints: The primary endpoint of this study will be successful identification of sentinel nodes on lymphoscintigraphy and SPECT imaging. The procedure will be considered feasible when one or more sentinel nodes can be identified and localized in at least 7 out of the 10 patients..
The Value of Repeated BIOMarker Measurements During an SBT to Predict EXtubation Failure in Mechanically Ventilated ICU Patients
Chronic cancer-related fatigue (CCRF) is a disturbing condition that persists in up to 25% of cancer patients after completion of treatment. While mindfulness-based interventions are effective in relieving CCRF, these typically target the patient alone. Growing evidence suggests that including partners and targeting the dyadic context can increase and broaden the interventions' efficacy. The proposed study is a pilot trial testing the acceptability and potential efficacy of a mindfulness intervention directed at couples.
The goal of this randomised controlled trial is to study the (cost-)effectiveness of home-based hypnotherapy by self-exercises in children with functional abdominal pain (FAP) or irritable bowel syndrome (IBS) in primary care. The main questions it aims to answer are: - What is the effect of home-based hypnotherapy by self-exercises on adequate relief of abdominal pain and discomfort in addition to care as usual of general practitioners (GPs), compared to care as usual of GPs alone in children with FAP or IBS? - What is the effect of home-based hypnotherapy by self-exercises in addition to care as usual by GPs compared to care as usual of GPs alone in children with FAP or IBS on: - Frequency and intensity of abdominal pain and discomfort - Pain severity - Daily functioning and impact - Anxiety and depression - Pain beliefs - Sleep disturbances - School absence - Use of health care services, including GP visits and referrals to secondary care - Costs (healthcare and societal perspective) Participants in the intervention group will receive home-based hypnotherapy 5 times a week for approximately 15-20 minutes a day during 3 months in addition to care as usual by their GP according to the Dutch society of GPs' guideline for children with abdominal pain. Participants in the control group will receive care as usual by their GP according to the Dutch society of GPs' guideline for children with abdominal pain.
