Multicenter, randomized, 6-week, double-blind, placebo-controlled, parallel-group, Phase 2 study in subjects with LBDP.
NCT04940936
A Patient Decision Aid (PtDA) is developed during a workshop in close collaboration with selected patients. The PtDA is subsequently used in the consultation between patient and physician to facilitate their shared decision on the dose of stereotactic body radiation therapy (SBRT) for lung tumors located less than 1 cm from the thoracic wall. Hypothesis: The use of a PtDA will increase the extent of Shared Decision Making (SDM) during the consultation and result in patients being more directly involved in the planning of their treatment.

Background Bariatric surgery (BS) is an efficient treatment of severe obesity and diseases like female infertility. Almost half of the population having BS are women of reproductive age, and BMI above 35 kg/m2 and infertility even serve as eligibility for surgery. BS improves fertility, however with risk of adverse effects on maternal glucose regulation and fetal growth. Objective We hypothesize that pregnant women with BS have a higher frequency of both hypo- and hyperglycemia causing abnormal fetal growth, and that Roux-en-Y gastric bypass (RYGB) results in higher risk of hypoglycemia and larger glucose variability than sleeve gastrectomy (SG). Methods In this prospective, multicenter study, we will include 225 pregnant BMI, age, and parity-matched women from four obstetric departments: 75 with RYGB, 75 with SG and 75 without BS. Data include continuous glucose monitoring, activity tracking, blood sampling, questionnaires, and fetal growth. Discussion Knowledge on prevalence, clinical significance and treatment of maternal glucose excursions and fetal growth in pregnancy following BS are lacking. This study will help clinicians improve the care of pregnant women with BS and to guide women of reproductive age considering BS.

This phase II trial studies the effect of transarterial chemoembolization in treating patients with uveal melanoma that has spread to the liver (liver metastases). Transarterial chemoembolization involves the injection of a blocking agent (gelatin sponge, ethiodized oil) and a chemotherapy agent (carmustine) directly into the artery in the liver to treat liver cancers. Chemotherapy drugs, such as carmustine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. transarterial chemoembolization with carmustine in combination with ethiodized oil and gelatin sponge may help cause the tumors in the liver to shrink or disappear.

The aim of this study is to learn whether using MRI (magnetic resonance imaging) scans to plan radiotherapy is better than using CT (computed tomography) scans alone. The main questions it aims to answer is: * Can MRI scan images be adjusted to make the tumour and normal tissues easier to see? * Does adding MRI to a radiotherapy planning CT make the radiotherapy plan more precise? * Can MRI be used to adjust a radiotherapy plan during a course of treatment to make it more precise, and might that reduce the side effects? * Are there particular MRI scans that can predict how a tumour will respond to radiotherapy or how likely the patient is to have side effects? This study will assess current MRI scanning procedures and ensure these are adjusted to best suit radiotherapy planning. It will also provide pilot data evaluating: 1. MRI-adapted radiotherapy Usually, radiotherapy plans are based on a pre-treatment planning CT scan. Unless an issue is detected the patient would complete their whole course of radiotherapy on this plan. This does not account for changes in position/size/shape of the tumour that occur over the whole treatment course. Clinicians therefore increase the size of the tumour/target to account for these uncertainties, which can increase side effects. This study will assess the potential to reduce side effects from radiotherapy by using repeat MRI scans and replanning during the treatment course (MRI-adaptive radiotherapy). 2. Imaging biomarkers MRI sequences can be used to predict response to radiotherapy or chance of developing side effects. This study will identify potential MRI sequences that may be used as imaging biomarkers, to guide the development of future clinical trials. The study will be undertaken at SBUHB, lasting 4 years, and involving ≤15 healthy volunteers and ≤150 patients.

Hyperspectral retinal imaging is a non-invasive imaging modality in which a series of images of the retina are captured using light of different wavelengths. The resulting "hypercube" of data provides a wealth of information about the retinal structure. Our group has developed evidence supporting a role for this technology in the detection of retinal amyloid beta in Alzheimer's disease. We are undertaking further studies to establish the role of this method in the assessment of people with dementia, or those at risk of Alzheimer's disease. In addition, we wish to test whether the approach may have value in other forms of dementia or neurodegenerative disease such as Parkinson's disease, Lewy-Body dementia or vascular dementia.

The goal of this interventional study (clinical trial) is to learn if different breath-holding techniques, with and without extra oxygen, can improve the quality of abdominal Magnetic Resonance Imaging (MRI) images in healthy adults, ages 18-75. The main questions it aims to answer are: * Does breath-holding at end-expiration improve image quality in abdominal MRI scans? * Does adding oxygen while breath-holding further reduce motion artifacts in abdominal MRI scans? Researchers will compare breath-holding with and without oxygen to see if using oxygen improves image quality during MRI scans. Participants will: * Be pre-screened for MRI safety and trained on breath-hold procedures * Have one non-contrast abdominal MRI scan at the University of California San Francisco (UCSF) China Basin Imaging Center * Use two different breath-holding techniques during the scan, with and without oxygen * Complete one study visit lasting about 45 minutes to 1 hour
NCT07509606
Chronic obstructive pulmonary disease (COPD) is an irreversible disorder characterized by persistent airflow limitation and increased lung compliance. It leads to dyspnea, skeletal muscle dysfunction, impaired functional capacity, and reduced quality of life. Physical inactivity is considered a major contributor to symptom deterioration, the development of a vicious cycle, and ultimately increased mortality. According to the American College of Sports Medicine (ACSM), the American Thoracic Society (ATS), and the American Association of Cardiovascular and Pulmonary Rehabilitation (AACVPR), pulmonary rehabilitation should include aerobic and resistance exercise for at least 20 minutes per session, performed three to five times per week for a minimum of 12 weeks. Exercise intensity should be progressively increased to exceed 60% of peak oxygen uptake (VO₂peak), and patients are encouraged to maintain long-term exercise habits. However, there is still no consensus regarding the optimal initial intensity, progression strategy, and exercise duration. Previous studies have demonstrated that whole-body vibration (WBV) can improve lower extremity muscle strength, functional capacity, and quality of life in patients with COPD. However, its effects on lung function and the optimal training dose remain unclear. In addition, COPD also affects respiratory muscles, upper extremity strength and flexibility, as well as cardiac autonomic function. Therefore, the aim of this study is to investigate the effects of different WBV frequencies on lung function, respiratory muscle function, upper extremity strength and flexibility, and cardiac autonomic function, in order to determine the optimal training dose.

The discovery of the Mirror Neuron System (MNS) has promoted the development of rehabilitation techniques such as Action Observation Treatment (AOT) and Motor Imagery (MI). These are based on the principle that neural circuits active during execution, also activate during the observation or imagination of movements. These techniques have been found to be effective in several clinical populations including children with Cerebral Palsy (CP), the most common childhood-onset motor disorder. We hypothesize that a multimodal version of AOT, integrating not only visual stimuli (standard practice) but also auditory and tactile stimuli, could further enhance the activation of the MNS. In fact, everyday actions naturally involve multiple sensory channels, and evidence indicate that audio-visual action observation activates the MNS more intensely than visual stimuli alone, thus offering a potential improvement for CP rehabilitation. The primary aim of this observational pilot study, conducted at IRCCS Fondazione Stella Maris, is to verify whether a multisensory (=immersive) AO session - combining visual, auditory, and tactile stimuli - produces greater activation of the MNS, than a traditional session (visual AO alone). Neural correlates will be measured through high-density Electroencephalography (hdEEG), with a specific focus on the modulation of the sensorimotor mu rhythm. Twenty children and adolescents with CP, aged 7-25 years, and 20 typically developing (TD) aged-matched peers will be recruited in the study. The study also aims to assess the level of participants' attention during stimuli presentation through eye tracking, and to verify whether immersive AO can influence MI abilities, measured through specific tasks and questionnaires (i.e., Motor Imagery Questionnaire for Children (MIQ-C, aged 7-12) and the Motor Imagery Questionnaire - 3 (MIQ-3) for adolescent). In an initial phase of the study both questionnaires will be the validated in a separate sample of 120 TD Italian children and 120 Italian adolescents or adults. The absence of intellectual disability will be assessed using the age-appropriate version of Raven's Progressive Matrices test. Each participant will undergo two EEG sessions: the immersive session will consist of watching first-person videos accompanied by auditory stimuli consistent with the action and tactile stimuli provided by TouchDIVER Pro haptic gloves (Weart, CE-marked device), suitably adapted for the paediatric population. The traditional session will consist of watching videos without sounds or any tactile additional stimulus. The two sessions will be performed in a in random order. In both sessions, after the observation phase, participants will be asked to perform or imagine the same actions presented in the videos. During observation, eye movements and gaze behavior will be monitored using an eye tracking system. Throughout each session, cortical activity will be recorded using a 128-channel hdEEG net. The sessions will be video-recorded to accurately monitor participants motor behavior, response times, and compliance with the protocol. At the end of each EEG session, participants will be administered the MIQ-C or MIQ-3 questionnaire and a short task to assess MI abilities. In this task, participants will watch some of the videos previously used during the EEG session and will then be asked to imagine the same action. In this case, their imagery will be interrupted at specific time points, and they will be asked to select, from two images, the moment of the action corresponding to the point at which they were interrupted. Data analysis will examine within- and between-groups differences for the immersive AO vs the traditional AO. Correlation analysis will be also performed between neurophysiological data, attentional data, questionnaires, MI responses and standardized clinical assessments ( for the CP group), in order to understand how the participants' motor and cognitive abilities influence the activation of the circuits involved in the experimental tasks.
NCT07111663
This is an observational study in individuals with isolated (or primary) dystonia that involves more than one body region. The purpose of the study is to collect detailed information to help your physician and other researchers understand how dystonia impacts your and other patients' lives and how the disease changes over time. The study may also help researchers better understand the clinical scales that are commonly used to evaluate dystonia symptoms and how they affect various areas of life such as well-being, pain, relationships and social interactions, and progress over time. Because this is an observational study, you will not receive any interventional treatment in the study.

Patients with prostate cancer and pelvic lymph node involvement (cN1M0) identified on PSMA PET imaging represent a biologically aggressive yet potentially curable disease population. Contemporary management relies on multimodality treatment combining definitive radiotherapy to the prostate and pelvic lymph nodes with long-term androgen deprivation therapy (ADT), often intensified with androgen receptor pathway inhibitors. Despite these advances, a substantial proportion of patients still develop distant metastatic disease, highlighting the need to optimize local-regional treatment strategies in the era of molecular imaging. The introduction of PSMA PET has fundamentally altered staging accuracy in prostate cancer, enabling earlier and more precise detection of pelvic nodal disease. However, most existing evidence guiding radiotherapy dose prescription in node-positive prostate cancer originates from the pre-PSMA era. As a result, it remains unclear how best to integrate prostate-directed and nodal-directed dose escalation strategies when disease extent is defined by modern molecular imaging. In particular, it is unknown whether long-term disease control is primarily driven by durable intraprostatic tumor eradication, by aggressive treatment of involved lymph nodes, or by a combination of both. PRO-BOOST-N is a prospective, multicenter, randomized phase II/III clinical trial designed to address this critical evidence gap. The trial evaluates prostate-first versus combined prostate and nodal dose escalation strategies in patients with PSMA PET-staged node-positive (cN1M0) prostate cancer treated within a standardized ultrahypofractionated whole-pelvis radiotherapy framework. All enrolled patients indicated for definitive treatment undergo mandatory baseline PSMA PET/CT to confirm pelvic lymph node involvement and exclude distant metastatic disease. All patients receive a uniform radiotherapy backbone consisting of ultrahypofractionated whole-pelvis radiotherapy delivered in five fractions, combined with long-term ADT. Use of androgen receptor pathway inhibitors is permitted and encouraged according to contemporary clinical practice and local availability, ensuring the relevance of the trial to real-world treatment settings. Using a 2×2 factorial randomized design, PRO-BOOST-N evaluates two independent treatment factors. The primary randomized comparison assesses whether ablative prostate dose escalation improves oncologic outcomes compared with contemporary SBRT-based definitive prostate radiotherapy without additional boost. Prostate dose escalation may be delivered using one of three protocol-defined modalities-high-dose-rate brachytherapy, low-dose-rate brachytherapy, or single-fraction SBRT-according to institutional expertise. This comparison directly tests the hypothesis that durable intraprostatic disease control is the dominant determinant of long-term systemic disease suppression in node-positive prostate cancer. The key secondary, hierarchically tested comparison evaluates the role of nodal dose escalation by comparing two predefined dose levels delivered to PSMA PET-positive pelvic lymph nodes. These dose levels reflect intermediate versus higher nodal boost strategies based on biologically effective dose concepts specific to prostate cancer radiobiology. To ensure patient safety and protocol feasibility, organ-at-risk-driven nodal dose de-escalation is permitted within the higher-dose arm, without altering randomization assignment. The primary endpoint of the trial is metastasis-free survival. Secondary endpoints include overall survival, radiographic progression-free survival assessed primarily using PSMA PET imaging, intraprostatic and regional nodal control, time to castration-resistant prostate cancer, time to next systemic therapy, treatment-related toxicity graded according to CTCAE version 5.0, and patient-reported outcomes assessing urinary, bowel, sexual, and global quality of life. By prospectively and hierarchically evaluating prostate and nodal dose escalation strategies within a modern PSMA PET-guided and ultrahypofractionated radiotherapy platform, PRO-BOOST-N aims to define the optimal radiotherapy intensification approach for patients with node-positive prostate cancer. The results of this study are expected to directly inform clinical practice, guideline development, and future treatment individualization in the PSMA PET era.

Lewy Body Dementia (LBD) is the second most common form of degenerative dementia, affecting at least 2.4 million US adults, and the overwhelming majority of persons living with LBD (PLBD) are cared for by family caregivers. LBD caregiver strain: 1) exceeds that of non-LBD dementia caregivers; 2) worsens caregiver physical and mental health; and 3) increases the risk of PLBD hospitalization and institutionalization. LBD progression is complicated by combined motor, cognitive, and neuropsychiatric decline, and is punctuated by falls, infections, dehydration, and neuropsychiatric symptoms leading to acute healthcare utilization. Although family caregivers are uniquely positioned to identify and manage these challenges, which may avert emergency department visits and reduce morbidity, many caregivers lack the knowledge, skills, confidence, resources, and support to do so. The study team aims to 1) quantify the impact of PERSEVERE on caregiver knowledge, attitudes, mastery, and strain; 2) identify the intervention and mentor factors determining implementation fidelity; and 3) test the effects of PERSEVERE on PLBD quality of life and healthcare utilization. This will be accomplished in an NIH Behavioral Model Stage II national, randomized, attention-controlled, 12-week trial of PERSEVERE in 502 LBD caregivers in partnership with the Lewy Body Dementia Association, Parkinson's Foundation, and LBD Caregiver Advisors. The study team will match intervention arm caregivers with a trained peer mentor who will coach them through a modular, theory-based curriculum on LBD knowledge and social support. Attention-control participants will receive weekly, curated links to educational materials. The study team will identify immediate and delayed intervention effects, including mediators of strain at 12 weeks, and caregiver strain and PLBD outcomes at nine months. Implementation fidelity and PLBD healthcare utilization will be tracked biweekly. Qualitative methods will explore the intervention- and mentor-specific factors predicting fidelity, mentee outcomes, and retention. Remote recruitment, mentoring, and community engagement strategies will maximize accessibility and inclusion of underrepresented caregiver groups. Results will illuminate the extent to which leveraging prior LBD caregivers as expert interventionists can improve current caregiver outcomes, and in turn, PLBD outcomes. These results will inform future adaptation and dissemination of this model for other conditions.
NCT06738160
Introduction: Immunotherapy in combination with chemotherapy have been recommended as the first-line treatment of driver-negative advanced non-small cell lung cancer (NSCLC), but the efficacy is worse in NSCLC patients with bone metastases due to the immunosuppressive microenvironment. Studies have shown that not only the nuclear factor kappa-B ligand (RANKL) inhibitors but also Stereotactic Body Radiation Therapy (SBRT) play a significant role in improving the tumor immune microenvironment. Therefore, narlumosbart，a monoclonal antibody (mAb) targeting RANKL，in combination with SBRT may have synergistic effects and improve efficacy of immunotherapy and chemotherapy in driver-negative advanced NSCLC patients with bone metastases. Methods: This single-arm, single-center phase II clinical trial will enroll NSCLC patients with bone metastases who have not received any systemic therapy. Patients will receive narlumosbart and bone target lesion SBRT in combination with first-line treatment immunotherapy and chemotherapy after screening eligible subjects. Narlumosbart, 120mg/time, subcutaneous injection, is administered every 4 weeks. For the treatment of SBRT for bone metastases, the dose of 24Gy/3F is used for spinal metastases, and 30Gy/5F or 35Gy/5F is used for non-spinal lesions. Chemotherapy combined with immune checkpoint inhibitor therapy was used in accordance with the guidelines. The primary endpoint is to assess the objective response rate of NSCLC patients with bone metastases from narlumosbart combined with SBRT and first-line chemotherapy and immunotherapy. The secondary endpoints include progression-free survival, overall survival and safety. Sample size calculation used the Simon Two-Stage method. 9 patients will be enrolled in the first stage. If ≥ 2 patients achieve CR/PR, the second stage of enrollment will be performed. If only 2 patients \< achieve CR/PR, the trial will be terminated. In the second phase, 15 patients will be enrolled. 27 subjects will be enrolled in this project, considering the dropout rate of 10%. Wangjun Yan AND Zhengfei Zhu are the Co-Principal Investigators of this study.

Seminal studies in motor neuroscience involving healthy subjects have revealed time-locked changes in induced power within specific frequency bands. Brain recordings were shown to exhibit a gradual reduction in signal power, relative to baseline, in the mu and beta frequency bands during an action or during motor imagery: the event-related desynchronization (ERD). This is considered to reflect processes related to movement preparation and execution and is particularly pronounced in the contralateral sensorimotor cortex. Shortly following the completion of the task, a relative increase in power, the event-related synchronization (ERS), could be observed in the beta band. ERS is thought to reflect the re-establishment of inhibition in the same area. Ever since the characterization of the ERD and ERS phenomena, there has been little to no discussion in the field of non-invasive Brain Computer Interfaces (BCI) as to whether these features accurately capture the task-related modulations of brain activity. Recent studies in neurophysiology have demonstrated that the ERD and ERS patterns only emerge as a result of averaging signal power over multiple trials. On a single trial level, beta band activity occurs in short, transient events, bursts, rather than as sustained oscillations. This indicates that the ERD and ERS patterns reflect accumulated, time-varying changes in the burst probability during each trial. Thus, beta bursts may carry more behaviourally relevant information than averaged beta band power. Studies in humans involving arm movements have established a link between the timing of sensorimotor beta bursts and response times before movement, as well as behavioural errors post-movement. Beta burst activity in frontal areas has also been shown to correlate with movement cancellation and recent studies show that activity at the motor unit level also occurs in a transient manner, which is time-locked to sensorimotor beta bursts. Although beta burst rate has been shown to carry significant information, it still comprises a rather simplistic representation of the underlying activity. Indeed, complex burst waveforms are embedded in the raw signals, and can be characterized by a stereotypical average shape with large variability around it. The waveform features are neglected in standard BCI approaches, because conventional signal processing methods generally presuppose sustained, oscillatory and stationary signals, and are thus inherently unsuitable for analysing transient activity. In contrast to beta, activity in the mu frequency band is oscillatory even in single trials. This activity is typically analysed using time-frequency decomposition techniques, which assume that the underlying signal is sinusoidal. However, there is now growing consensus that oscillatory neural activity is often non-sinusoidal and that the raw waveform shape can be informative of movement. In this project, the design of a subject-specific neurophysiological model to guide motor BCI training will be optimized using Magnetic Resonance Imaging (MRI) and Magnetoencephalography (MEG) for high spatial and biophysical specificity in the experimental group. Anatomical MR volumes will be used to design and 3D-print an individual head cast that will be used in the MEG scanner to stabilize the head position and minimize movements. This high-precision approach (hpMEG) has been proven to significantly improve source localization up to the level of distinguishing laminar activity, which makes it superior to EEG recording technique. An individualized hpMEG approach, as well as the widely adopted EEG, will be used to study bursts of oscillatory activity in the beta and mu frequency bands related to motor imagery and motor execution. hpMEG will yield subject-specific models of motor imagery that will be used to constrain online decoding of EEG data. This approach will be applied and validated on a group of healthy adult subjects and will then be compared against another feasibility group of patients and age-matched healthy participants. The proposed approach will be compared with a classic EEG-based BCI approach. The information will be used to optimally guide subsequent EEG-based BCI training in the control group. After a thorough investigation in healthy subjects in this project, the feasibility of the approach will be evaluated in a few stroke patients with upper-limb motor deficits. Tasks 1.1 and 1.2 aim to develop subject-specific generative models decoding movement onset and offset, the type of movement, as well as finely discretized movement amplitude during both real and imagined wrist extensions/flexions. Task 1.2 investigates how lesions of patients alter our ability to decode attempted wrist movements.
