Polysomnography (PSG) and drug-induced sleep endoscopy (DISE) are widely used diagnostic studies for assessing obstructive sleep apnea (OSA) severity and collapse patterns of the upper airway anatomy during sleep. Hypoglossal nerve stimulation (HNS) therapy for obstructive sleep apnea suffers from variable response at the level of the soft palate. The Investigators propose a study examining the physiologic effect of ansa cervicalis stimulation (ACS) alone and in combination with HNS during PSG and DISE.

This phase I/II trial studies how well tiragolumab and atezolizumab works when given to children and adults with SMARCB1 or SMARCA4 deficient tumors that have either come back (relapsed) or do not respond to therapy (refractory). SMARCB1 or SMARCA4 deficiency means that tumor cells are missing the SMARCB1 and SMARCA4 genes, seen with some aggressive cancers that are typically hard to treat. Immunotherapy with monoclonal antibodies, such as tiragolumab and atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

This phase II/III compares the standard therapy (chemotherapy plus cetuximab) versus adding bevacizumab to standard chemotherapy, versus combination of just bevacizumab and atezolizumab in treating patients with head and neck cancer that has spread to other places in the body (metastatic or advanced stage) or has come back after prior treatment (recurrent). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of cancer cells. This may help keep cancer cells from growing. Cisplatin and carboplatin are in a class of chemotherapy medications known as platinum-containing compounds. They work by killing, stopping, or slowing the growth of cancer cells. Docetaxel is in a class of chemotherapy medications called taxanes. It stops cancer cells from growing and dividing and may kill them. The addition of bevacizumab to standard chemotherapy or combination therapy with bevacizumab and atezolizumab may be better than standard chemotherapy plus cetuximab in treating patients with recurrent/metastatic head and neck cancers.

The vast majority of individuals with heart failure do not participate in center based cardiac rehabilitation (CBCR). While steps to increase utilization of CBCR are important, many individuals will still not participate for a variety of reasons. This pilot randomized controlled trial is evaluating a home-based cardiac rehabilitation (HBCR) intervention delivered using a custom app and digital tools in patients with heart failure. After a brief roll-in period, participants are randomized to one of two groups: (1) control or (2) HBCR mobile health intervention. The intervention targets key health behaviors and includes traditional cardiac rehabilitation components. The study will assess the effect of the intervention on physical activity, quality of life, clinical events, and other outcomes.

This phase II/III trial compares the effect of adding chemotherapy before and after surgery versus after surgery alone (usual treatment) in treating patients with stage II-III gallbladder cancer. Chemotherapy drugs, such as gemcitabine and cisplatin, 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. Giving chemotherapy before surgery may make the tumor smaller; therefore, may reduce the extent of surgery. Additionally, it may make it easier for the surgeon to distinguish between normal and cancerous tissue. Giving chemotherapy after surgery may kill any remaining tumor cells. This study will determine whether giving chemotherapy before surgery increases the length of time before the cancer may return and whether it will increase a patient's life span compared to the usual approach.

Women are at increased risk for Alzheimer's disease (AD). Notably at menopause, some women experience a change in cognition. However, not all women experience negative effects of menopause on cognition. The cognitive changes that occur at menopause have not yet been connected to late life risk for pathological aging including AD. Thus, understanding the neurobiological factors related to individual differences in cognition at menopause is critical for understanding normal cognitive aging and for determining risk for pathological aging. The challenge in understanding the role of estrogen loss on the risk for AD is the long lag time between the hormonal changes at menopause and the clinical manifestations of AD. Thus, identifying how the hormone changes after menopause are related to AD risk will alter the risk calculus for postmenopausal women in the future. The novel study proposed here will examine an established AD-related neurotransmitter-based mechanism that may also underlie cognitive changes after menopause. The investigators propose that the change in the hormonal milieu at menopause interacts with the cholinergic system and other brain pathologies to influence a woman's risk for cognitive decline. Preclinical studies have shown that estrogen is necessary for normal cholinergic functioning and its withdrawal leads to cholinergic dysfunction and cognitive impairment. It is important to determine whether menopause-related cognitive changes correlate with both cholinergic functional integrity and established AD biomarkers that portend increased risk for late-life cognitive impairment or dementia. This study will examine brain functioning following cholinergic blockade to separate individuals into those who are able to compensate for the hormone change after menopause and those who are not. The investigators hypothesize women with poor compensation have increased sensitivity to cholinergic blockade by showing poor performance on a cognitive task, altered brain activation, and decreased basal forebrain cholinergic system (BFCS) volume. These cholinergic markers will be related to menopausal factors associated with poor cognition and biomarkers of AD. Specific Aim 1 is to examine cholinergic functional "integrity" by measuring working memory performance, functional brain activation, and BFCS structure in postmenopausal women. Specific Aim 2 will examine whether individual differences in menopause-relevant symptoms and known AD biomarkers are related to cognition and brain activation after anticholinergic challenge. The public health significance of this study is that it will identify individual difference factors that are associated with cognitive performance changes after menopause and their relationship to structural, functional, and biomarker evidence of risk for later life cognitive dysfunction. Knowledge of these factors will serve to advance personalized future risk-mitigation strategies for women including hormonal, medication, cognitive remediation, etc. that will be the subject of further research.

Infections of the pleural space are common, and patients require antibiotics and chest drain placement to evacuate the chest from the infected fluid. Chest drains can get blocked by the drainage fluid and material. For this reason, it is thought that flushing the chest drain with saline solution, can help maintain the patency of the tube. This proposed study will evaluate the impact of regular chest drain flushing on the length of time to chest tube removal and total hospitalization as well as improvement in chest imaging and the need for additional interventions on the infected space.

This phase II trial tests whether using genetic testing of tumor tissue to select the optimal treatment regimen works in treating patients with clear cell renal cell (kidney) cancer that has spread to other places in the body (advanced or metastatic). The current Food and Drug Administration (FDA)-approved regimens for advanced kidney cancer fall into two categories. One treatment combination includes two immunotherapy drugs (nivolumab plus ipilimumab), which are delivered by separate intravenous infusions into a vein. The other combination is one immunotherapy drug (nivolumab infusion) plus an oral pill taken by mouth (cabozantinib). Nivolumab and ipilimumab are "immunotherapies" which release the brakes of the immune system, thus allowing the patient's own immune system to better kill cancer cells. Cabozantinib is a "targeted therapy" specifically designed to block certain biological mechanisms needed for growth of cancer cells. In kidney cancer, cabozantinib blocks a tumor's blood supply. The genetic (DNA) makeup of the tumor may affect how well it responds to therapy. Testing the makeup (genes) of the tumor, may help match a treatment (from one of the above two treatment options) to the specific cancer and increase the chance that the disease will respond to treatment. The purpose of this study is to learn if genetic testing of tumor tissue may help doctors select the optimal treatment regimen to which advanced kidney cancer is more likely to respond.

The vast majority of cardiac rehabilitation eligible individuals do not participate in center based cardiac rehabilitation (CBCR). While steps to encourage participation in CBCR are important, many individuals will still not participate for a variety of reasons. This randomized controlled trial is evaluating a home-based cardiac rehabilitation (HBCR) intervention delivered using a custom app and digital tools in patients undergoing transcatheter heart valve interventions (THVIs). After a brief roll-in period, participants not intending to participate in CBCR are randomized to one of three groups: (1) control, (2) HBCR mobile health intervention with hands-off delivery, and (3) HBCR mobile health intervention with interactive delivery. Participants in the intervention groups (hands-off/interactive delivery) will also be randomized to continue the intervention for 12 weeks or 24 weeks. The intervention targets key health behaviors and includes traditional cardiac rehabilitation components. The study will assess the effect of the intervention on clinical events, physical activity, quality of life, and other outcomes. Those who intend to participate in CBCR will be followed in a registry.

The goal of this mechanistic clinical trial is to learn about the effects of medications called soluble guanylyl cyclase stimulators on vascular function and markers of kidney and brain injury in patients having heart surgery. The main questions it aims to answer are: 1. Does soluble guanylyl cyclase stimulation improve blood vessel function compared to placebo? 2. Does soluble guanylyl cyclase stimulation decrease markers of kidney injury and brain injury compared to placebo? Participants will be randomized to a soluble guanylyl cyclase stimulator called vericiguat or placebo, and researchers will compare vascular function and markers of brain and kidney injury to see if vericiguat improves vascular function and reduces markers of injury. This will provide important information to determine the underlying reasons that patients have some kidney and brain function problems after having heart surgery.

This phase III trial compares the combination of four drugs (daratumumab, bortezomib, lenalidomide and dexamethasone) to the use of a three drug combination (daratumumab, lenalidomide and dexamethasone). Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as lenalidomide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Daratumumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Anti-inflammatory drugs, such as dexamethasone lower the body's immune response and are used with other drugs in the treatment of some types of cancer. Adding bortezomib to daratumumab, lenalidomide, and dexamethasone may be more effective in shrinking the cancer or preventing it from returning, compared to continuing on daratumumab, lenalidomide, and dexamethasone.
