NCT05490290
Rationale: Diagnostic medical imaging is essential in health care and guides patient management decisions. Rapid advances in imaging technology have enabled diagnosis at an early disease stage. Nevertheless, striving for early diagnosis leads to substantial overuse of diagnostic tests (too many tests are performed) and overdiagnosis (diagnosed abnormalities that are unlikely to affect a patient's health or well-being), with dire consequences to patient outcomes and health care costs. Computerized decision support systems (CDSS), such as the European Society of Radiology (ESR) iGuide, have been developed to guide referring physicians at the point of care. Objective: The overall objective of this project is to promote the appropriate, meaningful, value-based and personalized use of medical imaging. The specific objectives of this study are to evaluate the trends over time with implementation of a CDSS to guide imaging referrals (ESR iGuide) in key outcomes related to the appropriate use of diagnostic imaging tests, and to compare these trends between departments randomized between implementation of the active intervention (with decision support) and the control condition (no decision support). Study design: The study will be performed as a multi-center cluster randomized trial with departments acting as clusters combined with a before-after-revert design. Four hospitals with each 8 participating departments for a total of 32 clusters will be included in the study. All departments will start with the control condition. Subsequently, stratified per specialty (surgical vs non-surgical), half of the departments - chosen at random - will switch to the active intervention while the other half in the control condition. Study population: The study population consists of patients of eligible participating departments for whom a diagnostic imaging procedure is considered, and for whom a diagnostic imaging request is entered in a computerized order entry in such a form that it is registered by the CDSS. Intervention: The control condition will consist of computerized order entry with structured data entry of the clinical indication and tracking of the imaging exams requested. The CDSS is implemented but without decision support and physicians are blinded to these referral guidelines. Without their knowledge their imaging requests are categorized as appropriate, under certain conditions appropriate, or inappropriate. They receive no feedback to their requests. In the active intervention the CDSS is implemented with decision support. Physicians are made aware of the referral guidelines and appropriate exams are suggested. Their imaging requests are categorized as appropriate, under certain conditions appropriate, or inappropriate and feedback is provided. Physicians are able to change their request in response to the feedback. In the revert condition decision support is removed to study the sustainable educational effect of temporary use of the system. Main study parameters/endpoints: The primary outcome is the proportion of inappropriate diagnostic imaging exams requested per cluster (department). Inappropriateness is determined by the decision support system and is based on the ESR imaging referral guidelines. Secondary outcomes are the overall absolute number of imaging exams ordered (total and by exam type), estimated medical radiation from diagnostic imaging in investigated groups, and estimated medical costs for diagnostic imaging from the healthcare system perspective in investigated groups. Amendment November 2023: At Johannes Gutenberg University Mainz, the CDSS could not be integrated into the hospital's internal computerized order entry system as required for the study. Therefore, departments from this hospital were not eligible for inclusion. Therefore, and 24 instead of 32 departments were from three locations (Augsburg, Kiel, Lübeck) were randomized accordingly. In a qualitative description of the process of integrating the CDSS in the local hospitals, Mainz will still be included.
NCT05729802
The current pandemic has revealed in-person simulation training and evaluation is vulnerable to disruption, and alternatives are needed which allow remote evaluation. The recently developed Microsoft Hololens headset device allows interactable holograms to be inserted into a user's workspace (mixed reality) - permitting the augmentation of existing clinical and training spaces with holographic (i.e. virtual) patients via the prototype HoloSIM software. This study is the first known research initiative aiming to demonstrate the feasibility and effectiveness of mixed reality for acute medicine training and assessment at a distance. Space, time, personnel, pandemic, and cost constraints limit opportunities for high-fidelity simulation exercises for post-graduate trainees at Sunnybrook. By developing and demonstrating the effectiveness of this new training modality, increased simulation exercises will lead to a higher quality education experience, better functioning teams, and better patient outcomes.
NCT06795347
Children of parents with severe mental disorders have an increased risk of mental disorders themselves, with more than half of this population diagnosed with a mental health condition during their life time. Already during early childhood, the risk of a mental health diagnosis is elevated by a factor 2-5, compared to children of parents without severe mental disorders. This highlights the need for preventive interventions. Mental health during early childhood is inextricably linked with early parent-child interaction. Sensitive parenting plays a crucial role in the socio-emotional development of the child, and severe parental mental disorders may affect the quality of parent-child interaction. Therefore, we will test the effect of an intervention promoting sensitive parenting on mental health outcomes of 1-3 years old children of parents with severe mental disorders. The intervention will be tested in a randomized clinical trial comparing the intervention "Video-feedback Intervention to Promote Positive Parenting and Sensitive Discipline" (VIPP-SD) delivered online to Care As Usual. Our hypothesis is, that children in the Intervention Group will display lower levels of behavioral problems and increased attachment security compared to children in the Care As Usual Group. The study will be conducted in the department of Child and Adolescent Psychiatry, Mental Health Services in the Region of Southern Denmark. Participants are mothers with a diagnosis of schizophrenia, bipolar disorder, emotionally unstable personality disorder or moderate to severe depression living in the Region of Southern Denmark with their 1-3 years old child, and the father/cohabitating partner. Participants will be recruited via psychiatric outpatient clinics in the region or on the basis of information from health registers. The primary outcome of the study is child behavioral problems. Secondary child outcomes are attachment security and mental health. Parental outcomes are parental stress and quality of life. Child cognition, parental psychiatric symptoms, childhood trauma, sensitivity, parental reflective functioning and service use data are also assessed in the study. Data are collected at baseline as well as 5 and 11 months after randomization. All participants will have the opportunity to receive feedback on their child's cognitive functioning and mental health status at baseline and at the end of the study. After baseline assessments, participants will be randomized to either intervention or the control group. The intervention, VIPP-SD, is delivered online apart from the first session, which is conducted as a home visit. VIPP-SD is based on attachment and social learning theory. It is manualized and consists of 12 individual sessions alternating between video-recording of mother and child in pre-defined everyday situations and review/discussion of the video recordings with the mother/parents. Focus of the intervention is the childs signals and needs, and how to promote healthy socio-emotional development of the child. VIPP-SD will be carried out by health care professionals trained and certified in VIPP-SD. Participants who are randomized to the control condition, Care As Usual, will continue as they did before enrollment to the study. Care As Usual is defined as any kind of help and support related to the social-emotional development and mental wellbeing of the child in the municipality or mental health services.
NCT03220035
This phase II Pediatric MATCH trial studies how well vemurafenib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with BRAF V600 mutations that have spread to other places in the body (advanced) and have come back (recurrent) or do not respond to treatment (refractory). Vemurafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
NCT06794034
The purpose of this study is to compare the efficacy of taVNS versus sham stimulation in reduing depressive symptoms in patients with epilepsy.
NCT04312399
The influence of postmenopausal hormone treatment on dementia is not clear. Dysfunctions in the metabolism of amyloid in the disease of Alzheimer result in an elevated presence of degradation products in cerebrospinal fluid. The degradation products in blood will be analysed during the trial, to get better insight in menopause and the start of hormonal therapy. Postmenopausal women with and without history of breast cancer will be recruited for the trial.
NCT06794346
The aim of the study is to elucidate the role of testosterone treatment in postmenopausal women's sexual function and their therapeutic safety.

NCT06792292
Cancer can develop in the colon, or large bowel. Examination of the colon with a tube fitted with a camera is called a colonoscopy. Colonoscopy allows detection of small growths in the colon, called "polyps". Polyps can often be removed during colonoscopy. Some of these polyps are called adenomas and can become cancer after several years. A good colonoscopy aims to find and take out as many of these polyps as possible. A quality indication of colonoscopy is the "adenoma detection rate" (ADR). It should be high, meaning many polyps are detected and taken out. New artificial intelligence devices to assist colonoscopy seem to increase the ADR, and maybe help prevent cancer even better than normal colonoscopy. The goal of this clinical trial is to compare the ADR when using standard colonoscopy to the ADR with artificial intelligence (AI)-assisted colonoscopy.
NCT04248725
The E-TIPS trial will evaluate an evidence-based, telehealth pain self-management intervention compared to standard care (a waitlist) for chronic pain in adults with physical disabilities who are employed. Participants from anywhere in the US will be randomized to either E-TIPS, a cognitive-behavioral pain self-management intervention delivered by telephone, or a waitlist control. Outcomes, including pain interference, will be assessed at baseline, mid-treatment, post-treatment, and 6-month follow up.
NCT06496945
This study seeks to understand the effects of adult day programs on older adults, especially those with dementia, and their caregivers. A prospective cohort study will be conducted in the Canadian provinces of Alberta, British Columbia, Manitoba, and Ontario. Participants will be (1) older adults with dementia who attend a day program, and their caregivers, and (2) older adults with dementia in the community who do not attend a day program, and their caregivers. The objectives are to (1) evaluate the effects of day programs on attendee and caregiver outcomes, and (2) compare day program use patterns, attendee and caregiver social identities, day program characteristics, and day program outcomes between the 4 provinces, and (3) to explore what attendee and caregiver social identities and day program characteristics are associated with study outcomes, and with day program attendance/non-attendance.

NCT03075748
The outcomes from prior clinical evaluation of the study device, including successfully treating 99% (84/85) of the intended target vessels and 96% (27/28) limb patency observed at one year, demonstrate the potential benefits of the device. When contrasted with open repair's significant complication rates and branch fenestrated device's significant anatomic and logistic limitations, the potential risk of the proposed novel graft does not outweigh the potential benefit of widened anatomic availability and improved patency rates. Given the potential benefits, the investigators feel that it is justified to expose the target patient population to the potential risk. The non-clinical testing performed by Medtronic and the clinical results reported by Sanford Health show adequate safety of the device to support an early feasibility study. The investigators would like to perform an early feasibility study under a defined and controlled protocol to collect prospective preliminary safety and device functionality data. The investigators believe an early feasibility study is most appropriate for this novel approach. The limited sample size allows adequate patient data to be collected under a controlled protocol without exposing a large patient population to the risk associated with a novel device design.
NCT01285479
The purpose of the Multi-National Gilenya Pregnancy Exposure Registry in Multiple Sclerosis (MS) is to continuously monitor, evaluate, and assess for major and minor teratogenic effects in the offspring of women exposed to fingolimod before (up to 8 weeks before last menstrual period (LMP)) and during pregnancy in routine clinical practice. The overall aim is to collect and evaluate data on maternal, fetal, and infant outcomes and compare it with reference populations.
NCT06785545
It has been shown in the literature that urinary CA19-9 levels are associated with the degree of hydronephrosis and the anteroposterior diameter of the renal pelvis. Additionally, this marker has been reported as a potential indicator of kidney damage related to obstructive uropathies. A study conducted in our clinic, which has yet to be published, investigated CA19-9 levels in children with hydronephrosis of different etiologies. It found a statistically significant difference in CA19-9 levels between children with neurogenic and non-neurogenic lower urinary tract (LUT) dysfunction (Evaluation of Spot Urine Carbohydrate Antigen 19-9, Sodium, Potassium, and Creatinine Levels as Biomarkers for Differential Diagnosis of Hydronephrosis and Detection of Kidney Damage in Children Aged 0-16: A Prospective Study, Kütükoğlu et al.). Based on this, the hypothesis was formulated that urinary CA19-9 might be a potential biomarker for indicating neurological deficits in children presenting with LUT symptoms. Therefore, this study aimed to compare CA19-9 levels in a larger group of children with neurogenic and non-neurogenic LUT dysfunction.
NCT03994653
Approximately 7,400 new cases of ovarian cancer are diagnosed each year in the United Kingdom (UK), and with over 4,000 women dying from the disease each year it is a particularly lethal form of cancer. The symptoms for ovarian cancer are not well known and vague, and most women are diagnosed at a late stage when the cancer has already spread around the abdominal cavity with poor prognosis. Novel methods are needed to improve earlier detection and thereby improve survival from this disease. The Cancer Loyalty Card Study (CLOCS) proposes to use loyalty card data from two participating high street retailers to investigate purchase behaviour as an opportunity for cancer symptom surveillance. The investigators aim to conduct a case-control study of ovarian cancer patients matched with women without ovarian cancer and to explore public preferences for how to communicate potential outcomes of the commercial and health data linkages back to individuals. Eligible participants will be women in the UK who own at least one loyalty card with the participating high street retailers. Of these women, those who have been diagnosed with ovarian cancer are eligible to participate in the study as cases, while women who have not been diagnosed with ovarian cancer are eligible to participate as controls. Upon choosing to participate, all participants will be asked to complete a short questionnaire about well-established ovarian cancer risk factors and common symptoms either in the clinic (cases) or online/from a packet in the mail(controls). This information will be used in risk assessment for ovarian cancer of participants, which will be used at the analysis stage.
