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.
Chronic suppurative otitis media (CSOM) is characterized by intermittent or continuous otorrhea lasting for longer than 6 weeks. Most cases can be treated conservatively using antibiotic drops and oral antibiotics. However, some cases will not respond to conservative treatment and demonstrate persistant discharge. In these cases, especially if a CT-scan shows opacification of the mastoid air cells, a mastoidectomy can be considered as treatment modality. In recent years, obliteration of the mastoid cavity following mastoidectomy is gaining popularity. However, the effectiveness of obliterating the mastoid in comparison to mastoidectomy alone is uncertain for CSOM. In this retrospective cohort study, our aim is to compare mastoidectomy to mastoidectomy + mastoid obliteration in a cohort of patients suffering from CSOM with mastoid involvement. The hypothesis is that obliterating the mastoid cavity will result in a higher frequency of dry ears and in a lower frequency of revision surgeries.
In recent years, mastoid obliteration (MO) after mastoidectomy has gained popularity. However, the choice for obliteration material has been a point of discussion. Autologous materials have the advantage of being freely available without cost.Synthetic materials on the other hand have unlimited supply, hold volume over time and have no risk of donor site morbidity. Comparative studies between materials are rare and the few available were unable to ascertain superiority. Our hospital has been utilizing the same material for obliteration since 2011: S53P4 bioactive glass (BAG). It since has become our main operating procedure to obliterate the mastoid cavity with BAG granules following both canal wall up (CWU) and canal wall down (CWD) mastoidectomy. This bioactive glass has several important characteristics, such as the retaining of volume over time and antibacterial properties. An important factor when selecting obliteration material is safety. Data on this was reported in several studies, but unfortunately these studies only investigated short-term safety in small and selected cohorts of patients, often without comparison. Additionally, large studies with extensive follow-up are necessary to detect rare complications and long-term pitfalls. Therefore, the aim of this study is to determine the safety of BAG in a cohort that encompasses all cases that underwent CWU+MO and CWD+MO in our institute and compare these results to a non-obliteration cohort. The main outcomes are short- and long-term safety, as indicated by surgical complications in the first year following surgery and revision surgeries during follow-up, respectively. We compare the obliteration cohort to the non-obliteration cohort, hypothesizing that obliteration results in a comparable or lower rate of complications and revision surgeries
The goal of this two-armed randomized controlled trial is to investigate the effectiveness of a new, individually tailored, brief behavioral training for parents of children with behavioral difficulties in general practitioners' practices. The main questions the study aims to examine are: 1. The short-term effectiveness of a brief and individually-tailored, behavioral parent training program in primary care settings on the severity of four daily rated target behaviors in specific home situations, compared to care as usual (CAU). 2. The short-term effectiveness of the brief parent training compared to CAU on secondary outcome measures: severity of the same four daily rated target behaviors in other home situations, severity of child disruptive behaviors, number of child disruptive behaviors perceived as troublesome by the parents, overall impairment of child behavioral difficulties, impact of child behavioral difficulties on the relationship with parents, parenting behaviors, parenting stress and parenting self-efficacy. 3. The longer-term outcomes (three month follow-up) of the brief parent training program on primary and secondary outcomes. 4. The satisfaction and acceptability of the brief parent training program in primary care settings as perceived by parents and child mental health workers. Parents will be randomly assigned (simple and parallel randomization) to (a) the intervention condition in which parents receive three sessions of brief parent training and may receive CAU, or (b) the control condition in which parents may receive CAU. The brief parent training provides parents with individually tailored stimulus control and contingency management techniques to treat children's behavioral difficulties in two (bi)weekly training sessions of two hours and a third session of one hour in which the training will be evaluated and maintenance training will be provided. CAU may include any support or treatment as regularly provided by general practices, mental health care centers, schools and/or other organizations, except from pharmacological treatment for children's behavioral difficulties and/or behavioral parent training/support. CAU may also imply that there is no support or treatment. After the first posttreatment assessment (T1) parents in the control condition will be offered the brief parent training as well.
Post-Covid syndrome, also known as long Covid, is a clinical condition in which patients experience long term symptoms after Covid-19 infection. Treatment options for post-Covid are not effective. Therefore, there is an urgent need for a novel therapy. The first study results of HBOT in post-Covid patients are promising. Previous research from Israel has shown improvements in quality of life after HBOT. However, long term results are unknown. Therefore, this study aims to evaluate quality of life at one year after hyperbaric oxygen therapy in post-Covid patients with cognitive symptoms. It is hypothesized that quality of life at one year after HBOT is improved. Furthermore, this study aims to evaluate return to work after HBOT. To our knowledge this was not done before. An observational prospective cohort study will be conducted to answer the research questions. All post-Covid patients who are treated with hyperbaric oxygen therapy in participating centers, will be eligible for inclusion. Questionnaires and medical doctor consultations will be used in order to collect all data. There are no risks for participants, since only 7 questionnaires are not part of standard clinical care. The burden is approximately 40 minutes extra in total for participants, compared to standard clinical care.
The FAME-II trial was a prospective, multicenter, multinational, multi-continental, randomized clinical trial with an 'all comers' design. The overall purpose of the FAME-II trial was to compare the clinical outcomes, safety and cost-effectiveness of FFR-guided PCI plus optimal medical treatment (OMT) versus OMT alone in patients with stable coronary artery disease and in whom both PCI and medical treatment can be considered on the basis of the presently existing scientific evidence. FAME-II was conducted from 2009 to 2012 and 1-year, 2-year and 5-year results have been published. The purpose of this 10-Year Follow-up is to evaluate the 10-year major adverse cardiac event rate (MACE, defined as all-cause death, documented myocardial infarction, unplanned hospitalization leading to urgent revascularization). Patients will have to sign a specific informed consent for the present 10-year follow-up. This study will be conducted for about approximately 6 months.
This study is exploring whether it's possible to detect paragangliomas (a rare type of tumor) during minimally invasive surgery by using a technique called near-infrared fluorescence imaging, guided by a substance called indocyanine green (ICG). The goal is to see if this method can help surgeons identify and treat paragangliomas more accurately and during minimally invasive procedures.
The objective of this prospective, international cohort is to incorporate the low stable pressure (using Airseal Insufflator) approach and its associated parameters into the early rehabilitation program after colorectal surgery so as to shorten hospitalization up to the ambulatory care and reduce postoperative pain and opioid consumption.
This study assesses the amino acid concentrations in subject serum after intake of different types of proteins. The study is divided in two consecutive sub-studies. Subjects will be asked to ingest a specific protein blend each visit in a randomized order, after which blood will be drawn on 14 different time points. At least 48 hours will be kept between each visit, and the subjects receive a follow up call within 4-14 days after visit 4.
A substantial part of children/adolescents with anxiety or obsessive-compulsive disorder (AD/OCD) do not profit substantially from first-choice treatment (i.e., cognitive behavioral therapy; CBT). For them, no evidence-based treatment is available. The aim of this project is to evaluate and optimize a newly-developed personalized, short, and intensive exposure-based intervention, 'HANDS-ON', for 'treatment non-responders'. Collaboration with children, parents and teachers, guided exposure in a child's natural environment, personalized treatment goals and meaning/motivation are central principles. Methods: A multiple baseline single-case experimental design is used (qualitative and quantitative). Participants are children/adolescents (10-18 years; N=12) with an AD/OCD diagnosis for whom standard CBT did not lead to sufficient improvement. Children and parents are asked to complete questionnaires before, during, and after the treatment. Children, parents, and school professionals will be asked to participate in qualitative interviews to evaluate their experiences with the HANDS-ON treatment program.
The goal of this single centre cohort intervention study with historical controls, is to investigate the effect of implementing continuous antepartum electrophysiological CTG (eCTG) monitoring at the Obstetric High Care (OHC), on perinatal and maternal outcomes and obstetric care. The main aim is to investigate the effect of both monitoring methods on: - primary outcome: perinatal outcomes (a composite of perinatal mortality or major neonatal morbidity) until hospital discharge - secondary outcomes: Maternal mortality, neonatal morbidity, satisfaction for both patient and caregiver, duration of pregnancy, switch of monitoring method, duration of admission to the OHC, timing (planned or emergency) and number of obstetric interventions (such as caesarean section), and admission and duration of admission to the NICU (neonatal intensive care unit). Eligible women will be prospectively included in the cohort receiving standard treatment: CTG monitoring intermittent up to three times a day. From these eligible women, a random sample (464) of the prospective cohort (511) will be offered to receive a new monitoring method: 24/7 eCTG monitoring. In order to strengthen the comparison between the two groups (eCTG and standard treatment), additional data from 1400 women who received standard treatment in 2014-2019 will be collected retrospectively.
