NCT07328815
The goal of this randomized controlled trial is to evaluate whether behavioral nudges can reduce automation bias, the uncritical acceptance of automated output, in physicians using large language models (LLM) like ChatGPT-5.1 for clinical decision-making. The main question it aims to answer is: Does a dual-mechanism behavioral nudge intervention (baseline accuracy anchoring plus case-specific color-coded confidence signals) reduce physicians' uncritical acceptance of incorrect LLM recommendations? Researchers will compare physicians who receive LLM recommendations along with a behavioral nudge to those who receive LLM recommendations without the nudge to assess if the nudge reduces automation bias. Participants will: * Evaluate six clinical vignettes accompanied by LLM-generated recommendations (half containing deliberate, clinically significant errors). * Control group: Be able to view LLM recommendations in standard format without the nudge. * Treatment group: Be able to view ChatGPT's diagnostic accuracy on standard medical datasets as an initial anchor, then receive color-coded confidence signals alongside each recommendation (e.g., red for low confidence). * Have their responses evaluated by blinded reviewers using an expert-developed assessment rubric to detect uncritical acceptance of erroneous information.
NCT07082218
Following adolescent concussion, poor sleep health is common and relates to the development of persisting post-concussion symptoms, and uninjured adolescents (independent of concussion) also commonly experience sleep insufficiency. Given the sparse guidance that exists for clinicians to provide evidence-based sleep health recommendations for adolescents with a concussion, the primary objectives of this prospective randomized clinical trial of adolescents with a recent concussion are to discover if a multidimensional and prescriptive sleep health intervention leads to: 1) faster symptom resolution time, better sleep quality, or longer sleep duration; and 2) improved sleep habits, mental health, or academic engagement, relative to standard-of-care post-concussion sleep health guidance. Findings from this research will provide the basis for more precise sleep health recommendations for adolescents who experience a concussion.
NCT07639333
The aim of this study is to assess the impact of non-invasive prenatal testing right after an early isolated miscarriage on mental health and on the patient's subsequent care in the year following the miscarriage
NCT07001670
This randomized controlled clinical trial aims to evaluate the effects of an 8-week tele-yoga intervention in individuals with lung cancer who have undergone lung resection surgery. The intervention group will receive supervised yoga sessions via online synchronous video conferencing, while the control group will continue with standard post-operative care. The primary outcome is exercise capacity (6-minute walk test), with secondary outcomes including pulmonary function, respiratory and peripheral muscle strength, physical activity level, dyspnea, fatigue, sleep quality, anxiety and depression, and quality of life. It is hypothesized that tele-yoga will improve physical and psychological recovery post-surgery and may serve as a feasible home-based pulmonary rehabilitation alternative.
NCT07613671
Asthma is a chronic inflammatory disease of the airways that results in tissue remodeling, airflow limitation, and bronchial hyperresponsiveness. This study aims to evaluate the long-term effects of photobiomodulation using an LED vest in the management of pediatric asthma. It is a randomized clinical trial involving children aged 6 to 17 years diagnosed with mild to moderate asthma, divided into two groups: an intervention group (using a vest with active LEDs) and a control group (using the vest turned off, simulating the intervention without light emission). The methodology includes clinical and functional assessments such as spirometry, the Asthma Control Test (ACT), the GINA questionnaire, and the Incremental Step Test (IST), which measures exercise tolerance. Photobiomodulation through LEDs promotes cellular biostimulation without thermal effects, modulating inflammatory processes and optimizing tissue regeneration. It is expected that the LED vest will contribute to improving pulmonary function, enhancing quality of life, and complementing conventional treatments. This project aims to advance the clinical application of photobiomodulation as an accessible and effective therapeutic alternative for pediatric asthma.
NCT07606989
The goal of this observational study is to learn if whole-genome sequencing (WGS) can help find the genetic cause in fetuses with structural abnormalities that remain unexplained after standard genetic testing (such as karyotyping, chromosomal microarray, or whole-exome sequencing). It will also learn how WGS results may affect pregnancy management and family decision-making. The main questions it aims to answer are: How often does WGS identify a genetic cause in these fetuses? Does WGS find more genetic causes compared to standard genetic tests? Can combining WGS with other molecular analyses help discover new disease genes or pathways? Researchers will compare WGS results to results from standard genetic tests to see if WGS finds more genetic causes. Participants are pregnant women whose fetuses have structural abnormalities seen on ultrasound or MRI, with negative results from routine genetic testing. Participants will: Undergo an invasive procedure (such as amniocentesis) or provide postnatal samples as part of their regular medical care Allow the use of leftover samples for WGS and additional molecular studies Be followed until after delivery to collect information on pregnancy outcomes and neonatal health
NCT07160868
The OSADA (Obstructive Sleep Apnoea in Difficult Asthma) trial is an open-label, randomized control trial investigating the impact of diagnosing and treating obstructive sleep apnoea (OSA) on a asthma control in patients with difficult-to-control asthma. Participants will undergo home-based sleep studies to assess for OSA and are then allocated to one of three arms: 1) Patients with OSA treated with CPAP (intervention group), 2) Patients with OSA not treated for OSA (control group) and 3) Patients without OSA (reference group). The primary objective is to evaluate whether treating OSA improves asthma control, symptom burden, and quality of life compared to untreated OSA and to patients without OSA. Secondary outcomes include exacerbation rates, sleep quality, and healthcare utilization. This trial aims to clarify the contribution of OSA to poor asthma control and the potential benefits of integrated sleep and respiratory care in this complex population.
NCT06201832
Cardiac amyloidosis (CA) has recently been reported as a common cause of heart failure with preserved left ventricular ejection fraction (HFpEF), with a prevalence of 6% in elderly HFpEF patients. However, the diagnosis of CA is still challenging and requires multiple costly investigations. Regardless of the type of CA, TTR or AL, early diagnosis significantly improves prognosis. In this study, the investigators aimed to determine the prevalence of CA in Tunisian HFpEF patients and to identify clinical and ultrasound criteria predictive of CA.
NCT07011394
Asthma is a common inflammatory respiratory disease affecting 11% of Canadians, but its diagnosis remains challenging, leading to delays in treatment or overtreatment. Spirometry with a reversibility test and bronchial provocation testing (BPT), considered the gold standard, are the reference diagnostic methods. However, access to BPT is limited as it is performed in hospital settings. Type 2 inflammation biomarkers, the fractional exhaled nitric oxide (FeNO) and blood eosinophils (EOS), represent a potential alternative. In addition to their prognostic and theragnostic value, these markers predict a good response to inhaled corticosteroids in individuals aged ≥ 6 years with asthma. However, their use remains restricted to pulmonologists in specialized clinics and is not recommended as a diagnostic tool in Quebec. Despite studies demonstrating their diagnostic value in specialized settings, these tests remain underexplored in primary care and insufficiently studied in children under 12 years. The objective of ou study is to evaluate the relevance and performance of FeNO and blood eosinophils in the diagnosis of asthma in children referred in primary care with non-diagnostic spirometry.
NCT07558863
This study aims to investigate whether a class of diabetes medications called GLP-1 receptor agonists (GLP-1RA), specifically semaglutide or polyethylene glycol loxenatide, can improve heart-related nerve damage in people with type 2 diabetes. This heart-related nerve damage is known as diabetic cardiac autonomic neuropathy (DCAN), which can cause problems such as fast resting heart rate, low blood pressure upon standing, and in severe cases, heart attack or sudden death. In this study, 60 adults with type 2 diabetes (ages 18-80) will be randomly divided into two groups. One group will receive standard diabetes care only, while the other group will receive standard care plus a once-weekly injection of either semaglutide or polyethylene glycol loxenatide for 6 months. Participants will undergo tests before and after the treatment period, including blood tests and non-invasive heart function tests (24-hour heart rate variability monitoring and cardiac autonomic reflex tests). The main goal is to see whether GLP-1RA treatment improves heart rate variability, a key sign of heart nerve function. The study also looks at changes in body weight, blood sugar control, and insulin resistance. This research may help determine whether GLP-1RA medications can protect against or improve diabetic heart nerve damage, beyond their known benefits for blood sugar control.
NCT01639690
The patient has inherited ß-thalassemia major through the genes. These genes have mistakes in them, so the body cannot make normal red blood cells. Stem cells are made in the bone marrow. They are the earliest form of blood cells. This study is being done to see if the investigators can make the stem cells produce normal red blood cells and hemoglobin. The investigators do this by collecting the stem cells. The genes with mistakes are removed from the cells. These cells are then treated so they have the corrected gene for making normal hemoglobin. These treated cells are given back to the patient through an injection (shot) in the vein. This is also known as gene transfer. In order for the body to accept these cells, the patient will need to receive a low dose of a drug called busulfan. It is a drug that will prepare the body to receive the new stem cells. This study will let the investigators know: * If it is safe to give the patient the treated stem cells * If the treated stem cells will go into the bone marrow without causing side effects. Gene transfer has been used for the past five years. It has been successful in treating many blood disorders. At least 20 patients have received the type of treatment that the patient will get on this study. This treatment for B-thalassemia major was developed at Memorial Sloan Kettering (MSK). It was studied for a long time in the lab before being given to patients.
NCT04469439
This study will be a prospective, observational study of patients who undergo endoscopic sinus surgery for cystic fibrosis-related chronic rhinosinusitis (CRS). Individuals who do not undergo surgery but are treated medically for CRS will also be enrolled to serve as a control group. Outcomes analyzed will include pulmonary, quality of life, and others.
NCT03439865
The purpose of this pilot study is to explore wither ivacaftor in refractory CRS patients will demonstrate safety and tolerability; restore CFTR-mediated Cl- secretions as measured by EDSPD testing; produce detectable improvements in validated measures of CRS including the SNOT-22 questionnaire, Lund-MacKay CT scan grading, and Lund-Kennedy endoscopic scores; and provide beneficial effects on readily measured markers of sinonasal inflammation and infection (IP-10, IL-8, and Pseudomonas CFUs).
NCT07544199
In recent years, the growing awareness of the multifactorial nature of neurodevelopmental disorders has stimulated interest in transdiagnostic approaches aimed at investigating underlying etiological mechanisms beyond traditional diagnostic categories. In this context, the present study seeks to provide a transdiagnostic profiling of both domain-general cognitive functions (attention, working memory, executive control) and domain-specific functions (phonological awareness, rapid naming, vocabulary, reading) underlying the main neurodevelopmental disorders in a large sample of preschool and school-age children (3-11 years), through the use of CRAB (Computerized Reading-related Assessment Battery). CRAB is a digital platform specifically developed by SUPSI and the Université de Genève to integrate, within a single testing environment, the assessment of the main domain-general and domain-specific cognitive functions underlying neurodevelopmental disorders. In particular, participating families will receive an email containing a link to access the CRAB platform, which will not include their personal data but rather a code provided by the staff of IRCCS Medea. A screen will open displaying several game-like tasks designed to measure both domain-general and domain-specific cognitive functions, which must be completed by the participating subject. The main objective is to obtain a fine-grained and multidimensional mapping of cognitive profiles prior to the standard diagnostic process, in order to identify early patterns of (a)typical or at-risk functioning.
NCT07532876

The primary objective of this study is to evaluate a blood-based screening test for Colorectal Cancer (CRC).
NCT07516964
Nephrotic syndrome is a kidney condition that mainly affects children and is characterized by high levels of protein in the urine, low levels of protein in the blood, and swelling. While many children respond well to steroid treatment, a large proportion experience relapses or become dependent on therapy. In some cases, the disease does not respond to standard treatments and may progress to chronic kidney disease. Recent research suggests that, in addition to genetic factors, immune system mechanisms may play a key role in the development and progression of nephrotic syndrome. In particular, some patients produce autoantibodies against nephrin, an essential protein of the kidney filtration barrier. These autoantibodies may be associated with disease activity and treatment response. The aim of this study is to investigate the presence of anti-nephrin autoantibodies in children with nephrotic syndrome and to better understand their role in disease mechanisms and clinical outcomes.The study will also explore the presence of other autoantibodies targeting components of the glomerular filtration barrier. The study will use advanced laboratory techniques, including blood tests and detailed analysis of kidney biopsy samples, to identify these antibodies and their relationship with kidney structure and function. By integrating laboratory findings with clinical data, this study aims to improve the understanding of nephrotic syndrome and support the development of more personalized diagnostic and therapeutic strategies, with the goal of improving patient outcomes and reducing unnecessary or ineffective treatments.
