NCT04864691
Background The management of patients with symptomatic nonacute intracranial artery occlusion (sNA-ICAO), which is a special subset with high morbidity and a high probability of recurrent serious ischemic events despite standard medical therapy (SMT), has been clinically challenging. Some small-sample clinical studies have also discussed endovascular recanalization for sNA-ICAO; however, there is currently a lack of evidence from multicenter, prospective, large-sample cohort trials. The aim of our present study was to evaluate the technical feasibility and safety of endovascular recanalization for sNA-ICAO. Methods and analysis: Our group is currently undertaking a multisite, nonrandomized cohort, prospective registry study enrolling consecutive patients presenting with sNA-ICAO at 15 centers in China between May 1, 2020, and April 30, 2023. A cohort of patients who received SMT and a cohort of similar patients who received ER plus SMT were constructed and followed up for 2 years. The primary outcome is the composite of stroke/TIA within 2 years following enrollment and stroke/TIA ipsilateral to the target vessel. The secondary efficacy outcome includes the following two parts: 1) the incidence of stroke/TIA ipsilateral to the target vessel within 30 days and 90 days in both groups; 2) the all-cause mortality, mRS score, NIHSS score and cognitive function at 30 days, 90 days, 8 months, 12 months and 24 months for both groups, including the MRI, CTA/MRA, CTP or MRP results in patients with internal carotid artery or middle cerebral artery occlusion as well as CTA in patients with basilar or vertebral artery occlusion at 90 days, 12 months and 24 months. Descriptive statistics and linear/logistic multiple regression models will be generated. Clinical relevance will be measured as relative risk reduction, absolute risk reduction and the number needed to treat. Ethics and dissemination This study protocol was reviewed and approved primarily by Beijing Tiantan Hospital, the Capital Medical University Medical Ethics Committee, and the institutional review boards of all partner sites. The study is being externally monitored, and the results will be published in open-access peer-reviewed scientific journals and presented to academic and policy stakeholders.

NCT06087406
The purpose of this study is to determine the safety and tolerability of imvotamab in patients with moderate to severe rheumatoid arthritis who have failed prior therapies. Participants will be given imvotamab or placebo through a vein (i.e., intravenously). A placebo is a look-alike substance that contains no active drug
NCT06831578
The aim of this study is to compare the perioperative analgesic effect of ultrasound guided thoracic paravertebral block and ultrasound guided serratus anterior block in patients undergoing thoracotomy.
NCT06831708
This study is a randomized controlled trial designed to compare the effectiveness of two types of short-term psychotherapy-psychoanalytic therapy and Cognitive Behavioral Therapy (CBT)-in treating Generalized Anxiety Disorder (GAD). A total of 60 adult participants with a confirmed diagnosis of GAD will be enrolled and randomly assigned to one of three groups: one group will receive psychoanalytic therapy, a second group will receive CBT, and a third group will serve as a control (waiting list) group. Each treatment group will participate in 12 weekly sessions, with each session lasting 50 minutes. In the psychoanalytic therapy group, therapy will follow a standardized framework based on core psychoanalytic principles such as exploring unconscious conflicts, transference, and resistance. While this approach is flexible, all therapists will be trained and calibrated to apply these core principles consistently. In contrast, the Cognitive Behavioral Therapy (CBT) group will receive a structured, manualized intervention specifically designed for Generalized Anxiety Disorder (GAD). The control group will not receive any active psychotherapy during the study period but will continue to receive any standard care they are already using. The primary outcome of the study will be the change in anxiety symptoms measured by the Beck Anxiety Inventory (BAI) from before treatment to after the 12 sessions. Secondary outcomes will include measures of quality of life (using the World Health Organization Quality of Life Instrument \[WHOQOL-BREF\]), depressive symptoms (using the Beck Depression Inventory-II \[BDI-II\]), functional impairment (using the World Health Organization Disability Assessment Schedule II \[WHODAS II\]), the quality of the therapeutic relationship (using the Working Alliance Inventory \[WAI\]), and overall treatment satisfaction. The study is designed to be completed within a six-month period: one month for recruitment, one month for baseline assessments and clinical checks, and three months for the intervention. Data will be collected at baseline and immediately after the intervention, with the goal of analyzing and publishing the results as soon as possible following treatment completion. This study has received ethical approval from the Üsküdar University Ethics Committee and is intended to inform future research on effective treatments for Generalized Anxiety Disorder (GAD).
NCT06832020
Our interest in studying how pediatric patients develop after epilepsy surgery stems from the fact that difficult-to-control epilepsy causes changes in the brain's formation or functioning, leading some patients to experience slower development compared to others. By gaining a better understanding of how pediatrics patients fare after epilepsy surgery, specifically regarding their independence in daily activities (such as bathing or making the bed), their relationships with family and friends, their mobility, and their speech (whether it is understandable) we can learn more about patient recovery. The goal of this research is to determine whether, 4 years after epilepsy surgery, pediatrics patients show improvements in development. This study is important because it investigates what happens to the development of children who have undergone epilepsy surgery after a long period has passed since the procedure. Research focusing on long-term post-surgical outcomes is necessary, especially in pediatrics, as a brain is not fully developed and requires time to recover after surgery.
NCT06832267

NCT06740656
MEK inhibitors (trametinib, cobimetinib, selumetinib or binimetinib) have been used since 2016 to treat metastatic melanoma, by targeting the MAPK pathway Neuromuscular complications (neuropathy, myasthenia or myositis) have been reported in patients treated with MEK inhibitors. With the growing use of these new oncology therapies, neurologists, oncologists and other clinicians are likely to be increasingly confronted with MEK inhibitor-induced neuropathy, myasthenia or myositis. Yet, so far, these complications have only been documented in a few single case reports. Our aim was to characterize the neuromuscular complications associated with MEK inhibitors used either alone or in combination.
NCT06831799
Patients with red blood cell disorders (RBCDs), such as Sickle cell disease (SCD) and Thalassemia, are chronic, life-threatening conditions that can become multi-organ complications over time, and are likely at an increased risk of COVID-19-related complications. Patients at the highest risk include the elderly (\>50 in our population), those with a history of respiratory or cardiac disease and those with other comorbidities. Several patients affected by RBCDs undergo splenectomy as therapeutic option to improve their level of hemoglobin concentration. Splenectomized patients, or in the case of SCD with functional hyposplenism, are more vulnerable to bacterial infections / superinfections after viral infection. Acute pulmonary syndrome (ACS) is the main cause of morbidity in SCD in middle-high income countries, and is often triggered by infectious events. Currently, there is no literature on the subject. Thus, any recommendation available comes from the experience gained with previous Coronaviruses infections. Accordingly, the correct treatment and management of infection by Coronavirus SARS-COV-2 (COVID-19) in patients affected by RBCDs may be challenging given the rapid spread of the pandemic and limited literature so far, especially in some countries. Accordingly, there is an urgent need to pool evidence in a unique repository on patients affected by RBCDs and COVID-19 in order to reach critical numbers to facilitate the medical decision making process across Europe. The Registry on patients with rare RBCDs and COVID-19 is an initiative conceived in the core of the European Reference Network on Rare Hematological Diseases (ERN-EuroBloodNet, FPA 739541, www.eurobloodnet.eu) aiming at supporting medical practice of COVID-19 in these patients by gathering evidence on pediatric and adult COVID-19 confirmed cases in RBCDs across Europe.
NCT06557499
This investigation is designed to evaluate the performance rate of two polyurethane male condoms with different sizes and thicknesses versus a standard natural rubber latex (NRL) male condom. The purpose of this study is to see how well the experimental condoms perform compared to the latex rubber condom (for example, how often the different condom types break or slip off the penis). Sponsor also wants to find out how well couples like using the three condom types and whether they experience any problems when using the condoms (for example, irritation or discomfort).
NCT05841927
Neurodevelopmental disorders are a group of developmental disorders, including autism spectrum disorders (ASDs), attention deficit hyperactivity disorder (ADHD) and others, that begin at a developmental stage and severely affect the growth and development of the brain. Autism spectrum disorder (ASD) encompasses a group of neurodevelopmental syndromes characterized by deficits in social interaction and communication as well as repetitive behaviors and restricted interests. There is strong evidence for the involvement of inherited genetic factors in ASD (accounting for at least 80% of the variation in disease risk). There is strong evidence for the involvement of inherited genetic factors in ASD (accounting for at least 80% of the variation in disease risk). According to a meta-analysis, monogenic mutations in SHANK3, which encodes the major postsynaptic density (PSD) scaffolding protein at excitatory glutamatergic synapses, are found in approximately 0.69% of ASD cases and up to 2.12% of all moderate to profound intellectual disability cases. De novo mutations, interstitial deletions, and terminal deletions have been identified in ASD. Recent studies have shown that children with ASD have significantly lower levels of docosahexaenoic acid (DHA) than those without. Studies have shown that higher DHA intake reduces the risk of schizophrenia, bipolar disorder, depression, anxiety disorder, and conduct disorders. After DHA treatment, most children with ASD showed clinical and biochemical improvements, with increased DHA levels as measured by blood analysis and significant improvements in social scale scores in the supplement group. Moreover, increasing DHA levels in children with ADHD through dietary supplements can improve behavior, attention, literacy, cognitive problems, and working memory function. Therefore, for neurodevelopmental disorders, high DHA intake may be an important component of disease prevention.

The goal of this clinical trial is to compare in the pk/pd profiles of magisterial dexamfetamine and Tentin in adults with Attention Deficit Hyperactivity Disorder (ADHD). The main question\[s\] it aims to answer are: Q1: is there a difference between pk/pd profiles of the two forms of dexamfetamine? Q2: how does the pharmacokinetic variability influences the objective and subjective (side) effects experienced by adult patients with ADHD? Participants will: * take the Quantified behavior Test for analysis of objective effects. * undergo blood sampling for analysis of the plasma concentration of dexamphetamine. * undergo blood pressure and heart rate measurements. * fill out 4 types of questionnaires. Researchers will compare the outcomes between magisterial dexamphetamine and Tentin use in a crossover setting.
NCT06831656
Tetraselmis chuii (TetraSOD) is a marine microalgae that has been reported to improve antioxidant responses in human skeletal muscle cells treated with TetraSOD and to improve recovery from muscle damaging exercise in humans supplemented with TetraSOD. However, the effects of TetraSOD supplementation on endurance performance and physiology is less clear. This study assessed the effect of short-term TetraSOD supplementation on endurance performance and physiology in healthy adults.

The study aims to measure the effectiveness of social media in raising parental oral health awareness.
NCT06000787
The goal of the Molecular Characterization Trial (MCT) is to obtain biological specimens and data resources from patients enrolled on prospective trials, to ensure that the Harvard/UCSF ROBIN Center accomplishes its key objective of advancing our understanding of the biological mechanisms that underlie how radiation treats tumors but also can cause unwanted side effects. The MCT focuses on collection of research biospecimens before, during, and after radiation. Also critical to the MCT is the deep annotation of these research biospecimens with elements that complement each other to provide a holistic, detailed view of each patient. Annotated elements include those used in the past such as clinical and biological features but extend to factors we have so far neglected but must incorporate in the future such as dosimetry (precise anatomical measurement of radiation dose), artificial intelligence, computational biology, and natural language processing.
