Researchers are looking for new vaccines to prevent illnesses caused by a type of bacteria called Streptococcus pneumoniae. There are many different types of Streptococcus pneumoniae bacteria, called serotypes. Vaccines contain small parts of certain serotypes. These parts will not cause an infection but help the body create antibodies (proteins) to fight the bacteria. PREVNAR 20™ is a vaccine given to help to prevent disease from Streptococcus pneumoniae bacteria. Researchers designed a new vaccine, V118E, to help prevent disease from Streptococcus pneumoniae bacteria. The goal of this study is to learn how safe V118 formulation E is in Healthy Adults and how well people tolerate it.

This phase II trial studies how well nab-paclitaxel, durvalumab, and tremelimumab with or without personalized synthetic long peptide vaccine (neoantigen vaccine) works in treating patients with triple negative breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Chemotherapy drugs, such as nab-paclitaxel, 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. Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Vaccines made from peptides may help the body build an effective immune response to kill tumor cells. It is not yet known whether giving nab-paclitaxel, durvalumab, and tremelimumab with or without neoantigen vaccine will work better in treating patients with triple negative breast cancer.

This study evaluates a novel Virtual Reality (VR)-integrated visual feedback system designed to enhance limb propulsion during robot-assisted gait rehabilitation in individuals post-stroke. In collaboration with CUREXO, a rehabilitation robotics company, the system is embedded within the Morning Walk® end-effector robot and provides real-time visual feedback to facilitate symmetrical use of the paretic and non-paretic limbs. The goal is to address gait asymmetry commonly observed in hemiparetic stroke survivors by promoting improved paretic leg propulsion, which is a key contributor to forward movement during walking. A total of 30 participants (15 stroke, 15 healthy controls) aged 20 years or older will undergo single-session gait training using the VR-robot system. Participants will be assessed using spatiotemporal gait parameters, muscle activity, foot pressure, and vertical ground reaction forces. Additional safety measures-including a saddle-type weight support and real-time heart rate monitoring via smartwatch-are implemented to ensure a safe and controlled training environment. This study aims to test the feasibility and effectiveness of this VR-based system in improving gait symmetry and functional walking capacity in people recovering from stroke.

Ventilator associated events (VAE) is a quality metric defined by 48 hours of stability followed by 48 hours of escalation of ventilator settings within the ICU. VAE have been associated with poor outcomes and increases the cost of care, yet is not easy to avoid. Operationalizing all the standards of care known to improve outcomes of those requiring mechanical ventilation in the critical care environment requires a comprehensive approach. ICU teams are encouraged to follow best practice protocols to help liberate and prevent VAEs. Yet, compliance with protocols in most ICUs is suboptimal for multiple reasons. With the advent of computerized mechanical ventilators capable of streaming data from breath to breath and biomedical integration systems (BMDI) such as Capsule (UTMB's BMDI system), software systems have been developed to help identify variances in the standard of care. Automation in near real-time ventilator data feedback has been shown to reduce the incidences of VAEs. This quality improvement project will leverage Vyaire's Respiratory Knowledge Portal (RKP) to collect and store meaningful data regarding ventilator-associated events (VAE), alarm policy compliance, ventilator weaning, and lung protective analytics. Goals: 1. To collect quality metrics utilizing RKP from patients requiring mechanical ventilation over a 3-4-month period for a retrospective baseline analysis. 2. Provide the RKP tool to the ICU team to determine if the use of RKP's webportal and Messenger Zebra phone app improves quality of mechanical ventilation and outcomes. 3. To determine a return on investment (ROI) for a software system like RKP.

Weight loss surgery is very good at reducing body weight but it can also cause the loss of both muscle and strength. Some patients undergoing weight loss surgery do not achieve their weight loss goals and regain the weight they lost. When this occurs, the loss of muscle and strength combined with the regain of weight can impact the individual's quality of life and ability to remain active and mobile. The purpose of this study is to understand the behavioral, biological, and genetic factors that influence the success of weight loss surgery and its impact on muscle mass. Bariatric surgery patients participating in the trial will be monitored prior to, and for a year following weight loss surgery, with data collected about their eating habits, hand grip strength, and the loss of fat, muscle, and body weight following surgery. Some patients will be additionally invited to undergo detailed metabolic assessment, where we will measure how their body uses nutrients it consumes, the composition of their body (e.g. how much lean and fat tissue they have and where it is stored), identify the bacteria living in their gut, and determine their physical performance. In all patients a small sample of gut tissue will be collected at a routine endoscopy performed in advance of weight loss surgery to identify the expression (activity) of genes in their DNA. Healthy subjects will also be recruited to allow us to compare between healthy weight individuals and those undergoing weight loss surgery. On a single occasion, the healthy volunteers will undergo the same detailed metabolic assessment performed in patients as described above. We will not examine the bacteria living in the gut of the healthy volunteers, nor will we collect gut tissue from these individuals.

The study hypothesis is that BCG naïve non-muscle invasive bladder cancer (NMIBC) patients treated with intravesical Gemcitabine + Docetaxel (GEMDOCE) will result in a non-inferior event-free survival (EFS) compared to standard treatment with intravesical BCG. The purpose of this study is to test whether Gemcitabine + Docetaxel is a better or worse treatment than the usual BCG therapy approach. The primary objective of this study is to determine the event free survival (EFS) of BCG-naïve high grade non-muscle invasive bladder cancer patients treated with intravesical BCG vs Gemcitabine + Docetaxel. Secondary objectives are as follows: to compare changes in cancer-specific and bladder cancer-specific QOL from baseline to treatment between BCG-naïve high grade NMIBC patients receiving BCG and GEMDOCE, to determine the cystectomy free survival (CFS) of BCG-naïve high grade NMIBC patients treated with intravesical BCG vs GEMDOCE, to determine the progression free survival (PFS) of BCG-naïve high grade NMIBC patients treated with intravesical BCG vs GEMDOCE, and to determine the safety and toxicity of BCG-naïve high grade NMIBC patients treated with intravesical BCG vs GEMDOCE.

This phase I trial tests the safety, side effects, and best dose of ZEN003694 in combination with binimetinib in treating patients with solid tumors that carry RAS alterations and that have spread to other places in the body (advanced/metastatic) or cannot be removed by surgery (unresectable). ZEN003694 is an oral medication with potential anticancer activity. It is an inhibitor of a family of proteins called bromodomain and extra-terminal (BET) which play important role during development and cellular growth. ZEN003694 may stop the growth of tumor cells that produce BET. Binimetinib is in a class of medications called kinase inhibitors. It works by blocking the action proteins called MEK1 and MEK2, that signal cancer cells to multiply. It may help keep cancer cells from growing and spreading. There is pre-clinical evidence that using ZEN003694 and binimetinib together may shrink or stabilize cancers studied in this trial. There are two parts of this study; dose escalation and dose expansion. In the dose escalation part of this study, different people will get different doses of the study drugs ZEN003694 and binimetinib. In the dose expansion part of this study, the highest dose with manageable side effects will be given to additional people. This will help to understand the side effects that may happen with this drug combination.
