The goal of this observation study is to assess whether endoscopic ultrasound shear wave elastography (EUS-SWE) may be a useful tool for liver fibrosis screening in patients with elevated body mass index and non alcoholic fatty liver disease as compared to other non-invasive screening modalities, which have traditionally had less accurate results in this population. The main questions it aims to answer are: - Determine accuracy of EUS-SWE for liver fibrosis screening compared to other non-invasive scoring systems, such as the FIB-4 score and Fibroscan in patients with elevated body mass index - Establish optimal stiffness (kPa) cutoffs for liver fibrosis grading for EUS-SWE for this patient population in reference to the gold standard liver biopsy, as no standard cutoffs currently exist. Participants will undergo routine endoscopic ultrasound as part of their standard clinical care and indication. Participants are consented for the procedure and undergoing the shear wave elastography. In addition to their standard ultrasound test, it takes on average an extra 2-3 minutes to perform the shear wave elastography. The procedure itself adds no additional risk to the patient and does not expose them to radiation.

Postoperative pulmonary complications (PPCs) are a major cause of morbidity and mortality in surgical patients. National estimates suggest 1,062,000 PPCs per year, with 46,200 deaths, and 4.8 million additional days of hospitalization. The objective of the study is to develop and implement perioperative strategies to eliminate PPCs in abdominal surgery, the field with the largest absolute number of PPCs. We will conduct a randomized controlled pragmatic trial in 750 studied participants. The effectiveness of an individualized perioperative anesthesia-centered bundle will be compared to the usual anesthetic care in patients receiving open abdominal surgery. At the end of this project, the investigators expect to change clinical practice by establishing a new and clinically feasible anesthesia-centered strategy to reduce perioperative lung morbidity. The research will be conducted across 14 US academic centers, and will be funded by the National Institute of Health.

Laser treatment of hypertrophic burn scars has become increasingly popular for improving scarring in burn survivors. Despite its common use, there a gap in knowledge regrading randomized control trials that demonstrate whether the laser is beneficial. Such a trial is important because if it shows the laser does work, it would provide the evidence to make such treatments more accessible to all patients. Furthermore, there is no knowledge whether the burn injury used to remove tissue is beneficial or not. This study aims to evaluate the laser treatment, removal of similar tissue amounts with 0.5mm punch biopsies, to controls to fill this knowledge gap. The hypothesis is the laser is beneficial at improving patient's burn scars. Also the punch biopsies work better at improving scars by removing tissue without burning and injuring the surrounding tissue as the laser does. To evaluate these treatments (laser, punch biopsies, and no treatment), 3 small areas will be chosen in a study scar area that meets specific criteria to receive . Patients will still be able to receive laser and burn reconstruction procedures in all other areas not involving the study scar area that are clinically indicated. In the study, the scar will be evaluated with photographs, surveys, and tissue samples taken either while under anesthesia except for one set taken with numbing medicine. The tissue samples will be looked at under a microscope to see how the treatments change the scar tissue. The tissue will also have tests done to evaluate how the laser impacts genes from cells in the scar tissue. Lastly, to understand how reconstructive procedures (laser and surgical treatments) change a patient's quality of life, patients will be asked a limited set of questions to learn more how these procedures improve their lives.

Smokers living with HIV represent a major health disparity population in the United States and the world more generally. Major contributing factors to the maintenance and relapse of smoking among smokers living with HIV include increased exposure to multiple stressors associated with HIV, which often exacerbates anxiety/depression. In a previous project, the feasibility, acceptability, and initial efficacy of a 9-session, cognitive-behavioral-based intervention to address smoking cessation by reducing anxiety and depression via specific emotional vulnerabilities (anxiety sensitivity, distress tolerance, and anhedonia) was tested against an enhanced standard of care in a pilot randomized controlled trial (NCT01393301). It was found that when compared to a brief enhanced treatment as usual control, patients in the intervention achieved higher short-term and long-term smoking abstinence rates. In this project, the investigators seek to test this same intervention in a fully powered, 3-arm efficacy/effectiveness trial. The goal of this study is to randomize 180 smokers across three sites to test the efficacy/effectiveness of the intervention at increasing point prevalence abstinence by reducing anxiety and depression at a 1-month follow-up (the end of treatment timepoint/ approximately 1-month post quit day) and a 6-month follow-up (approximately 6-months post quit day).

Determining how memory T helper type 2 (Th2) initiate recall responses to aeroallergens has the potential to change the therapeutic approach to allergic asthma, the most common asthma subtype. ~5-10% of effector Th2 cells recruited into the lung give rise to long-lived tissue resident memory cells that are poised to respond upon allergen re-exposure.Consequently, targeting memory Th2 cell activation is an attractive therapeutic strategy. However, it is not well understood how allergen inhalation initiates a memory Th2 cell response in the lung. The focus of this new study on the role of lung-resident memory Th2 cells in orchestrating the recall response to allergen in the lung, including the recruitment and activation of circulating Th2 cells, is a natural, timely and exciting extension of the investigators' ongoing Allergen Challenge Protocol.

RBN-2397 inhibits PARP7, an enzyme that is switched on by cancer stresses, such as the toxins in cigarette smoke. Cancer cells use PARP7 to hide from the immune system by stopping the cell from sending a signal (Type 1 interferon) that tells the immune system that something is wrong and to kill the cell. RBN-2397 has been shown in animal studies to inhibit tumor growth and also shuts down the "don't kill me" signal the tumor is sending to evade the immune system. As a PARP7 inhibitor RBN-2397 is different from drugs inhibiting PARP1, PARP2 and PARP3 enzymes which are approved for the treatment of certain ovarian and breast cancers. The primary purpose of this study is to determine the maximum tolerated dose (MTD) of orally administered RBN-2397 in patients with advanced or metastatic solid tumors. This study will also evaluate the safety and tolerability of RBN-2397, examine the pharmacokinetics (PK) (measure how the body absorbs, breaks down and eliminates RBN-2397) and investigate whether it has antitumor activity in solid tumor cancers.

Fecal Incontinence (FI) affects 40 million Americans, predominantly women and elderly. It is a major health care burden, significantly impairs quality of life and psychosocial function. FI is characterized by multifactorial dysfunction including lumbosacral neuropathy, anorectal sensori-motor dysfunction, and abnormal pelvic floor-brain innervation. A critical barrier to progress in the treatment of FI is the lack of RCTs, absence of mechanistically based non-invasive therapies that modify disease, and a lack of understanding on how treatments affect pathophysiology of FI. Consequently, most current remedies remain ineffective. Our long-term goal is to address the problem of lack of effective treatments for FI by investigating treatments that modulate neuronal perturbations and thereby improve sensory and motor control, and to understand the neurobiologic basis of these treatments. Our central hypothesis is that a novel, non-invasive treatment consisting of Translumbosacral Neuromodulation Therapy (TNT), using repetitive magnetic stimulation, will significantly improve FI in the short-term and long-term, by enhancing neural excitability and inducing neuroplasticity. Our approach is based on compelling pilot study which showed that TNT at 1 Hz frequency, significantly improved FI, by enhancing bidirectional gut- brain signaling, anal sphincter strength and rectal sensation compared to 5 or 15 Hz. Our objectives are to 1) investigate the efficacy, safety and optimal dose of a new treatment, TNT, in a sham controlled, randomized dose-dependent study in 132 FI patients; 2) determine the mechanistic basis for TNT by assessing the efferent and afferent pelvic floor-brain signaling, and sensori-motor function; 3) identify the durability of treatment response and effects of TNT, and whether reinforcement TNT provides augmented improvement, by performing a long-term, sham controlled randomized trial. Our expected outcomes include the demonstration of TNT as a durable, efficacious, safe, mechanistically based, non-invasive, and low risk treatment for FI. The impact of our project includes a novel, disease modifying, non-invasive treatment, a scientific basis for this treatment, and improved understanding of the pathophysiology of FI and how TNT modifies bidirectional gut and brain axes and anorectal function. Ultimately, the knowledge generated by this project will provide new avenues for the development of innovative, evidence-based therapies for FI.

This research study is a Phase I clinical trial. Phase I clinical trials test the safety of an investigational intervention. Phase I studies also try to define the appropriate dose of the investigational therapy to use for further studies. "Investigational" means that the intervention is still being studied and that research doctors are trying to find out more about it. Retroperitoneal sarcomas are soft tissue tumors located at the far back of the abdomen. Typically, patients with retroperitoneal sarcomas either have surgery for the removal of their tumors alone, or have their tumors removed, followed by standard radiation therapy, or have pre-operative radiation followed by surgery. When conventional radiation therapy is delivered after surgery, it can damage normal tissue. In this study, you will undergo proton beam radiation therapy or IMRT before undergoing surgery for the removal of your tumor. Proton radiation and IMRT are FDA approved radiation delivery systems. Protons are tiny particles with positive charge that can be controlled to travel a certain distance and stop inside the body. In theory, this allows better control of where the radiation dose is delivered as compared to photons. Since proton radiation is more targeted, it may help to reduce unwanted side effects from radiation. In this study, a standard dose of radiation will be given to the majority of the tumor, while a simultaneously integrated boost of additional radiation will be given to certain areas of the tumor identified as higher risk. This means that a higher radiation dose will be given to the higher risk areas of the tumor. The purpose of this study is to determine the highest dose of radiation therapy with protons or IMRT that can be delivered safely in patients with retroperitoneal sarcomas and the effectiveness of proton beam radiation therapy as an intervention for patients with retroperitoneal sarcomas.
