This phase I/II trial studies the side effects of interstitial photodynamic therapy following palliative radiotherapy and how well it works in treating patients with inoperable malignant central airway obstruction. Patients who have advanced stage cancer tumors in the lung can often have the breathing passages to the lung partially or completely blocked. These tumors could be due to lung cancer or other cancers (e.g., renal, breast, kidney, etc.) that spread to the lung. This blockage puts the patient at a higher risk for respiratory failure, post-obstructive pneumonia, and prolonged hospitalizations. Treatment for these patients may include bronchoscopic intervention (such as mechanical removal, stenting, laser cauterization, or ballooning), radiation therapy with and without chemotherapy. While palliative x-ray radiotherapy may help in shrinking the tumor, high dose curative radiotherapy that can ablate (a localized, nonsurgical destruction) the tumor also has high risk to cause significant toxicity, including bleeding, abnormal connections or passageways between organs or vessels and abnormal scar tissue that can also produce airway obstruction. Photodynamic therapy (PDT) is another possible treatment that can provide local control of the tumor. PDT consists of injecting a light sensitive drug (photosensitizer, PS) into the vein, waiting for the PS to accumulate in the tumor, and then activating it with a red laser light. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Giving interstitial photodynamic therapy following palliative radiotherapy may improve tumor response and survival without the serious side effects that are associated with the typical high dose curative x-ray radiotherapy alone in patients with malignant central airway obstruction.

Stage 1: To select the optimal dose of naporafenib + trametinib to be studied in Stage 2. Stage 2: To compare progression free survival (PFS) and overall survival (OS) for patients with NRAS-mutant (NRASm) melanoma who are randomized to receive the combination of naporafenib + trametinib to that of patients who are randomized to physician's choice of therapy (dacarbazine, temozolomide, or trametinib monotherapy).

This is a multi-center, open-label, Phase 0 substudy designed to evaluate the localized pharmacodynamics (PD) of rilvegostomig, volrustomig, sabestomig, and AZD9592 within the tumor microenvironment (TME) when administered intratumorally in microdose quantities via the CIVO device in patients presenting with Head and Neck Squamous Cell Carcinoma (HNSCC) with a surface accessible lesion, who are scheduled for tumor and/or regional node dissection as part of their standard treatment. PD effects due to injected investigational agents, either as single agents or as AZD9592 drug combinations with the evaluated biologics, will be compared to those elicited by pembrolizumab alone, which will also be injected in microdose quantities via the CIVO device.

Purpose of research The purpose of this study was to demonstrate that polyethylene (Vitamin E-containing polyethylene), a newly introduced biomaterial for tibial inserts in hip replacement surgery and widely used clinically, but whose mid- to long-term clinical results are still unknown, is superior to conventional polyethylene in vivo. The aim of this project is to conduct an international multi-center joint research study to determine whether polyethylene wear debris production can be reduced in the future, using an in vivo polyethylene wear debris analysis method that the investigators developed as a method that can provide early feedback.

This is a prospective, observational study which is evaluating the obstetrical, neonatal, and cardiovascular outcomes of 1000 pregnant people with known heart disease to define how best to structure cardio-obstetrics care to optimize outcomes. Read Less

The purpose of this study is to look at how signals in the brain, body, and behavior relate to anxiety and memory function. This project seeks to develop the CAMERA (Context-Aware Multimodal Ecological Research and Assessment) platform, a state-of-the-art open multimodal hardware/software system for measuring human brain-behavior relationships. The R61 portion of the project is designed to develop the CAMERA platform, which will use multimodal, passive sensor data to predict anxiety-memory state in patients undergoing inpatient monitoring with intracranial electrodes for clinical epilepsy, as well as to build CAMERA's passive data framework and active data framework.

The goal of the study is to compare different types of high intensity circuit exercises over an 8-class training series in people with Parkinson disease. The main question it aims to answer is: -Does including arm and hand exercises with leg exercises improve reaction time, balance, functional measures, gait speed and quality of life? This group will be compared to a group that only does leg exercises. Participants will be asked to participate in 8 high intensity circuit exercise classes. Read Less

To assess the safety and tolerability of IVT GBS-06 vaccine administered as a single-dose regimen, at three dosage levels in healthy, non-pregnant, adult women of childbearing age (WOCBA). Read Less

The purpose of this study is to measure the incidences of pediatric emergence delirium between the group receiving Isoflurane and the group receiving Sevoflurane plus intravenous push dexmedetomidine. Read Less

The goal of this observational study is to find out what factors affect the health and risks in adults with glioblastoma (GBM), a grade 4 brain cancer. The main questions it aims to answer are: * How do genetic and immune system factors impact survival and quality of life in GBM patients? * What occupational and medical history factors are linked to the risk of getting GBM? Participants will: * Fill out an online survey about their medical history and lifestyle. Participants will have the chance to give a blood sample (from the outer arm) for genetic and immune system testing. Blood samples will be given using a home collection kit provided by the study team. Read Less

The goal of this survey is to assess several aspects related to patient preferences regarding interventions for alleviating tinnitus through invasive electrical brain stimulation (neuromodulation). This survey covers the acceptance of a surgically-placed brain implant, of its associated risks related to the neurosurgical procedure, usability considerations, and the willingness/ability to pay for such a treatment. Neurosoft Bioelectronics will use the collected patients' feedback and usability preferences data for the development of a novel minimally invasive brain implant aimed at alleviating tinnitus.

The major goal of this study is to evaluate a multi-component, multilevel HIV prevention intervention that targets theoretically-informed and empirically-identified barriers to and facilitators of both HIV testing and PEP/PrEP uptake by combining existing evidence-based and novel evidence-informed components and integrating them into a community-based organization's (CBO) standard of care (SOC) PEP/PrEP navigation program. The evaluation will apply use a 2x2 factorial design to randomize and follow for 18 months 480 PrEP-eligible Black MSM (aged 18-65) living in the NYC area to one of four combinations of interventions. The impact of the social/media campaign, delivered to both geographic (print media) and Black MSM communities (social media) and launched midway through recruitment, will be assessed through assessment of timing and length of exposure as covariates in analysis.
