Clinical trials

Parkinsonism impairs upper airway and axial motor control, leading to disordered breathing, reduced speech volume, and ineffective cough. Symptoms are poorly addressed by current therapies. This randomized pilot trial tests whether a single session of acute intermittent hypercapnic hypoxia (AIHH) or hypercapnic normoxia (AIHN) improves upper airway and axial motor function in Parkinsonism, and explores biomarker correlates of intervention responsiveness.

This is a pilot RCT examining physical activity outcomes at 3 months across 3 conditions: use of large language model (LLM) fully self-directed; use of LLM with guidance; and use of online tools to help with sleep.

The purpose of this study is to determine whether changes in attention levels related to taking a single dose of a medication called methylphenidate, also known as Ritalin, affects responses to alcohol cues. The study will observe the effects of methylphenidate or a placebo on neural and craving responses to alcohol cues through fMRI and behavioral testing. Participants will be involved in one remote and two in-person sessions.

This study aims to determine analgesic and anti-inflammatory effects of dual-wavelength PBM in people with symptomatic knee OA.

This prospective, double-blinded, placebo-controlled study evaluates the efficacy of a 6000 mg transdermal CBD cream in adults with plantar fasciitis. Fifty participants will apply either CBD or placebo once daily for one month.

This study evaluates whether multiparametric chest magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI), performed without any contrast material, can distinguish malignant from benign lung lesions that were assigned Lung-RADS category 4 on a standard-of-care lung cancer screening low-dose CT. Participants who have a Lung-RADS 4 lesion on screening CT undergo one non-contrast research MRI of the chest at 3.0 Tesla. The MRI is added to standard care; no standard-of-care imaging, biopsy, or treatment is withheld or replaced, and the research MRI is not used for clinical decision making. Participants then continue routine clinical management, and the final nature of the lesion is established from pathology or microbiology when tissue is obtained, or otherwise from at least 24 months of clinical and imaging follow-up. The primary measure is the sensitivity and specificity of multiparametric MRI against that final diagnosis. Secondary measures include whether DWI alone performs as well as the full MRI protocol, how MRI compares with PET/CT in participants who had PET/CT as part of their care, and quantitative MRI thresholds (apparent diffusion coefficient, lesion-to-spinal-cord signal intensity ratio, native T1 and T2). This is an exploratory pilot and feasibility study. No formal power calculation was performed; the sample size is intended to support feasibility assessment, protocol optimization, and preliminary estimates of diagnostic performance.

Concussion and depression have long been recognized to be intertwined pathologies.1-3 Although female athletes are more likely to suffer from mental health symptoms than males athletes following a concussion,2 research in this area has been largely biased toward males.4 Recently functional MRI (fMRI) studies5 in concussed athletes have established that there are patterns of local alterations in neural connectivity in the frontal cortex that demonstrate anatomic congruency with transcranial magnetic stimulation (TMS) studies that mapped alternations in neural connectivity to functional and somatic symptoms.6 Thus, there is potential that TMS treatment could decrease both symptom profiles, revolutionizing comorbid treatment options. Possible Benefits: Previous studies have showed a 70% remission rate for depression symptoms. It is possible that participants could have improvement in depressive or concussive symptoms after the ONE-D TMS treatment.

Fibromyalgia (FM) is a chronic musculoskeletal pain disorder that afflicts up to 4% of the general population. The evaluation of pain mechanisms in FM has shown predominant central abnormalities and therefore has been designated as nociplastic pain syndrome. Rheumatoid arthritis (RA) is characterized by polyarthritis and pain from inflamed tissues, consistent with nociceptive pain. FM and RA patients may utilize overlapping pain mechanisms resulting in nociceptive and nociplastic pain.

Adverse outcomes in surgical sepsis patients are secondary to dysregulated emergency myelopoiesis, and expansion of myeloid-derived suppressor cells. Here we propose to determine the underlying mechanisms behind the increased expansion of these leukocyte populations and the underlying mechanisms that drive inflammation and immune suppression.

Supracondylar femur periprosthetic fractures about a total knee arthroplasty (TKA) are a catastrophic and challenging complication of TKA and unfortunately are increasing in incidence. Fixation of these fractures can be challenging due to altered anatomy for the TKA and the presence of the metallic femoral component and have a relatively high complication rate. As a result, some surgeons elect to treat these fractures with a distal femur replacement total knee arthroplasty (DFR). The purpose of this study is to prospectively evaluate periprosthetic femur fractures treated with ORIF or DFR and compare various outcomes measures (Get up and go times, KOOS Jr score)

This pilot study will investigate the potential efficacy of VM100, a nutritional supplement specifically formulated for patients with DMD, on quality of life and physical symptoms. Twenty patients (aged 8 an over) will be enrolled to undergo a 10-week placebo-controlled intervention with VM100. Outcomes will include validated questionnaires and qualitative interview to assess impact on mental, cognitive and mood related measures, as well as endurance and fatigue).

The goal of this phase I trial is to evaluate the toxicity and feasibility of a tumor-specific RNA-NP vaccine in patients with stage IIB-IV melanoma who have evidence of progressive disease by RECIST 1.1 criteria while receiving adjuvant aPD1 therapy, or those who progress within 6 months of completion of adjuvant treatment, or unresectable stage II soft tissue sarcoma or stage III-IV soft tissue sarcoma.

Our overarching goal is to adapt and test the PINPOINT intervention -PatIent Navigation for the Prevention of CervIcal CaNcer inTervention. We will test the PINPOINT intervention among patients with high-risk profiles for cervical cancer who do not meet the recommended screening for cervical cancer.

Project CONTINUITY (Connecting You to Care in the Community) was developed to increase adherence to cervical cancer screening regimens from initial screening to needed follow-up care by (1) providing personalized approaches to improve adherence through the combined use of patient choice for the initial screening method (Pap/HPV co-testing vs. HPV self-test collection), community clinical navigators and community health workers (CHWs), customized messages and support for patient portal access for test results and (2) implementing strategies to address social determinants of health (SDoH) that may influence an individual's ability to adhere to the screening regimen, with an initial focus on removing transportation barriers through the use of a mobile outreach clinics (MOC).

This is a pilot study in a small number of children and young adults with suspected recurrent/progressive medulloblastoma (MB) looking at the feasibility and safety of adoptive cell therapy plus PD-1 blockade.

This project uses a hybrid trial design to evaluate two biomedical interventions targeting the gut-brain axis. One intervention is portable Transcutaneous Vagus Nerve Stimulator, tVNS, that is hypothesized to stimulate the autonomic nervous system, resulting in decreased inflammation and improved cognition. The second intervention is a probiotic supplement intended to replace gut bacteria that are associated with dysbiosis in persons with HIV and alcohol consumption.

The goal of this behavioral, interventional clinical trial is to provide a specialized workshop training for dental providers (e.g., dentists, hygienists, assistants) to improve interactions with young children (2-10 years old) and parents/caregivers. The training is derived from a well-established behavior management program for preschoolers, Parent-Child Interaction Therapy (PCIT). The main questions it aims to answer are: * Change in behavior of dental providers * Acceptability of training by dental providers All participants will receive the same behavior training; however, one group will receive the training on a delayed schedule. Researchers will compare the immediate intervention and control group to see if the training was effective in the dental providers usage of skills.

The goal of this observational study is to evaluate respiratory and limb muscle properties in adults awaiting lung transplantation and determine how these measures relate to physical performance, symptoms, and recovery after transplantation. Respiratory and limb muscle weakness may contribute to impaired mobility, frailty, and delayed postoperative recovery, but their specific role in lung transplant candidates is not well understood. Participants will undergo muscle ultrasound imaging at weekly basis, respiratory and limb strength testing, physical performance assessments, and symptom questionnaires once before and after transplantation. Researchers will also collect information from medical records regarding intensive care unit stay, hospital length of stay, rehabilitation participation, and postoperative recovery outcomes.

The purpose of the research is to evaluate the feasibility and benefits of a six-week hybrid task-oriented resistance exercise program for older adults who have been recently discharged from home health care.

Brain network segregation, or independent functioning, declines with age and is associated with slower walking speed. Here, the investigators will determine the extent to which brain vestibular network segregation can be altered with bilateral vestibular cortical transcranial direct current stimulation (tDCS) in older adults with subjective cognitive decline. Participants will be randomly assigned to an active or sham stimulation condition. They will receive three, 20-minute sessions of tDCS while they are walking and performing cognitive tasks. MRI of the brain will be acquired before and after these three sessions.

The goal is to determine whether three months of at least three times / week of sensory flicker stimulation improves cognition, mobility, and affect in healthy older adults and older adults with and without Subjective Cognitive Decline (SCD). Investigators will also determine whether the intervention slows cortical thinning and declines in brain functional network segregation and changes in blood biomarkers of Alzheimer's Disease (AD).

Deep brain stimulation (DBS) of the thalamus is an effective treatment for medically refractory essential tremor (ET). DBS involves delivering continuous stimulation to the brain through electrodes permanently implanted in the thalamus. Despite proven effectiveness, the long-term benefit of DBS can wane over time (habituation) and side effects, including paresthesia and dysarthria, often limit the amplitude of the stimulation, resulting in suboptimal control of tremor. In clinical practice, many groups advise patients to switch their devices off at night to avoid habituation and reduce side effects. However, manually turning off the device at night can result in uncontrolled tremor when the patient moves at night. This study aims to develop an algorithm that automatically turns off stimulation when a patient is asleep, based on circadian brain signals. Turning off stimulation could potentially improve the therapy by limiting adverse effects, increasing efficacy, reducing the risk of habituation, and prolonging battery life. This study will evaluate the feasibility, safety, and tolerability of circadian adaptive DBS.

Stigma due to health conditions increases disease burden and adversely impacts health. The internalization of health-related stigma is associated with impaired mental health and quality of life. The current project will test the effects of a novel, transdiagnostic, group counseling intervention, and peer support, to determine the optimal method for helping patients cope with health-related stigma, reducing its internalization, and enhancing patient quality of life.

The goal of this clinical trial is to learn if AB-free kava works to improve mobility and physical function in older adults with sleep difficulties. It will also learn about the safety of AB-free kava. The main questions it aims to answer are: * Does AB-free kava improve physical function and/or mobility? * Does AB-free kava effect sleep, stress, or cellular signaling? Researchers will compare AB-free kava to a placebo (a look-alike substance that contains no drug) to see if AB-free kava works to improve mobility and physical functioning.

The goal of this clinical trial is to adapt, implement, and evaluate MyCarePulse and ASCENT patient navigator to overcome barriers to care among patients with cancer. The main hypotheses it aims to test are: * At the patient level, the intervention will result in higher levels of food security, self- efficacy for dietary behaviors, and higher diet quality than standard care. * At the provider level, the intervention will be feasible, acceptable, appropriate, and able to enhance individualized care for patient wellness. Researchers will compare cancer patients receiving the MyCarePulse and ASCENT patient navigator intervention to those receiving standard care, to see if the intervention improves food security, self-efficacy, and diet quality.
