The purpose of this study is to conduct an early clinical evaluation of the Relay Branch System, which will provide initial insight into the clinical safety and function of the device. This Early Feasibility Study (EFS) will assess the safety and effectiveness of the device at the index procedure and at 30-day follow-up. The study will evaluate the delivery and deployment of the device, patency of branches and branch vessels, and exclusion of the aortic pathology. The data will help determine if modifications need to be made to the device, the procedural steps, operator technique, or the indications for use.

The purpose of this study is to evaluate the safety and efficacy of administering the medication capecitabine along with temozolomide when you start your monthly regimen of oral temozolomide for the treatment of your newly diagnosed glioblastoma multiforme (GBM). Capecitabine is an oral chemotherapy that is given to patients with other types of cancer. The study will evaluate whether the dosage of 1500 mg/m2 of capecitabine is tolerable after radiation, when taken along with temozolomide. It will also try to determine if the medication capecitabine helps patients respond to treatment for a longer period of time compared to just temozolomide alone, which is the standard of care.

After neoadjuvant chemotherapy, patients normally receive either conservative breast surgery or mastectomy followed by radiation therapy. Some patients achieve a complete response after neoadjuvant chemotherapy. Considering that radiation therapy is an effective treatment for subclinical microscopic disease, the question arises whether breast surgery before radiation therapy can be avoided in the subgroup of patients with complete response after neoadjuvant chemotherapy.

This will be a phase II single-arm clinical trial. The purpose of this study is to determine the feasibility of deescalating chemoradiation treatment based on mid-treatment tumor response determined by rapid nodal shrinkage and clearance of circulating HPV plasma tumor DNA . The primary objective of this study is to evaluate progression-free survival at 2 years.

Background: In people with multiple sclerosis (MS), brain and cerebrospinal fluid (CSF) biomarkers indicate inflammation or disease. Researchers want to see if 4 drugs given alone or combined affect MS biomarkers. They want to see if a change in biomarker levels can predict which drugs a person with MS might respond to. Objective: To see if signs of inflammation in CSF help predict a person s response to different drugs. Eligibility: People ages 18 and older who: Are in protocol 09-I-0032 Have progressive MS Can stand and walk a few steps Take an MS drug Design: Participants will be screened in protocol 09-I-0032. Participants will take 1 of the 4 study drugs. Researchers will call after 1 month to see how they are doing. Some will start a second drug. They may take each drug or combination for up to 18 months. Participants will have 2 visits a year for up to 6 years. Visits include: Medical history Physical exam Blood and heart tests X-rays and scans Eye exam and tear collection Lumbar puncture: A needle inserted between back bones removes some CSF. Lymphocytapheresis: Blood is removed through a needle in one arm and run through a machine. The blood is returned through a needle in the other arm. A sensor on the forehead records blood flow and oxygen use. Participants may get a device for testing at home. Participants will stop taking the drugs if they have taken 2 drugs together for 18 months or if they do not do well on the drugs. Participants will be called 3 months later to see how they are doing.

Use of Muscle relaxant and reversal with Sugammadex at end of airway procedures will reduce the time to extubation after end of procedure

Craniopharyngioma is a rare brain tumor that affects both children and adults. It arises in a region of the brain near the pituitary gland, visual pathways, and central blood vessels. Patients often present with headache, loss of vision or delayed growth. In some instances they may present with imbalance of water and salts in the body. The treatment for craniopharyngioma may be radical surgery or a combination of surgery and radiation therapy. In some instances surgery is not required. If the tumor cannot be completely removed, radiation therapy may be required. In this study we will use the most advanced form of proton therapy which is called intensity-modulated proton therapy. This is a newer form of radiation therapy which has a number of advantages over older forms of proton therapy and conventional radiation therapy using x-rays. The main goal of this study is to learn if proton therapy will effectively treat patients with craniopharyngioma brain tumors and reduce side effects compared to more traditional forms of radiation therapy.

Vast majority of patients with hepatocellular carcinoma (HCC) present with unresectable disease. In the last decade results of randomized trials and a subsequent metaanalyses established transarterial chemoembolization (TACE) or systemic chemotherapy (sorafenib) as standard of care. However, TACE alone is not a curative approach. The two year survival following TACE ranges from 31-63% with almost 100% patients developing disease progression after treatment. There is need to investigate additional therapeutic options that would consolidate the initial response to TACE. A recent metaanalyses concluded that addition of high dose radiation to TACE results in 10-35% improvement in two year overall survival. However as results of metaanalyses were based on studies with small sample size, unclear randomization procedure and heterogenous dose of radiation, the need for conducting a high quality randomized study was highlighted The present study is designed to investigate the role of high dose conformal radiation as consolidation therapy after TACE in patients with nonmetastatic unresectable HCC.

This study will be conducted in the ward of Taichung Veterans General Hospital. The patient with hyperglycemia in hospitalization will be enrolled by glucose management team.

This study consists of four parts, Parts A, B, C, and D. Part A is a single dose pharmacokinetic (PK) study in pediatric participants with Sickle Cell Disease ages 6 to 17 years. Part B is a multiple dose, safety, exploratory, efficacy, and PK study in adolescent participants with Sickle Cell Disease ages 12 to 17 years. Part C is a multiple dose, safety, tolerability, and PK study, which includes the assessment of hematological effects and the effect on TCD flow velocity of voxelotor in pediatric participants with Sickle Cell Disease ages 4 to 17 years. Part D is a multiple dose, safety, tolerability, and PK study, which examines the hematological effects of voxelotor in pediatric participants with Sickle Cell Disease ages 6 months to < 4 years.
