The goal of this exploratory study is to test a mind-body interventional approach for the treatment of chronic migraines. The main goal is to obtain feasibility information on the protocol which has been used in other similar conditions. We will also evaluate multiple measurement tools in order to optimize a follow-up pilot study evaluating the impact of the protocol on migraines.
The goal of this study is to test a new way to improve sleep quality in persons living with mild cognitive impairment. The treatment combines a safe and gentle way to stimulate the brain, called transcranial magnetic stimulation, with a psychological treatment, called cognitive behavioral therapy for insomnia.
Acute myelogenous leukemia (AML) arises from leukemia stem cells that are difficult to eradicate and serve as a reservoir for disease relapse following chemotherapy. A promising area of investigation is the development of immunotherapeutic approaches that stimulate the immune system to recognize leukemia stem cells as foreign and eliminate them. The purpose of this research study is to determine the safety of the Dendritic Cell AML Fusion Vaccine (DC AML vaccine) after participants have achieved a remission with chemotherapy. In this clinical trial, patients are treated with a tumor vaccine alone following standard of care chemotherapy. The DC AML vaccine is an investigational agent that tries to help the immune system to recognize and fight against cancer cells. It is hoped that DC AML vaccine will prevent or delay the disease from coming back.
The investigators' goal is to conduct a prospective multicenter study to evaluate the yield and outcomes of screening of pancreas cancer in individuals who are at-risk for pancreatic cancer. We plan to use International Cancer of the Pancreas Screening (CAPS3) Consortium recommendations to standardize study population, screening methodology, and study outcomes.
The goal of this prospective observational cohort study is to validate a previously developed pancreatic cancer risk prediction algorith (the PRISM model) using electronic health records from the general population. The main questions it aims to answer are:
Will a pancreatic cancer risk model, developed on routine EHR data, reliably and accurately predict pancreatic cancer in real-time?
What is the average time from model deployment and risk prediction, to the date of pancreatic cancer development and what is the stage of pancreatic cancer at diagnosis? The risk model will be deployed on data from individuals eligible for the study. Each individual will be assigned a risk score and tracked over time to assess the model's discriminatory performance and calibration.
Prostate cancer is the most common cancer in American men. Surgical removal of the entire prostate (prostatectomy) is one option among the various ways to treat prostate cancer. The use of robot assistance for prostatectomy has become common place, but its effectiveness has not been compared to standard open prostatectomy in trials carried out at more than one medical institution in which participants are identified and followed forward in time. Robot assisted and standard open prostatectomy health related quality of life (HRQOL) outcomes have not been compared in a prospective, multi-centered study. Prostatectomy can have side effects that can change with time. This research study seeks to determine how common and how long-lasting such side effects are; to find out what features of individual men's cancers and what features of the treatments affect those side effects. This study also seeks to identify factors that affect the quality of prostate cancer care by looking at how satisfied men are with their prostate cancer care. Through these findings, this study aims to allow treatment side effects to be anticipated more accurately for individual patients, and to provide a means for determining the quality of prostate care.
Hallucinations are a core diagnostic feature of psychotic disorders. They involve different sensory modalities, including auditory, visual, olfactory, tactile, and gustatory hallucinations, among others. Hallucinations occur in multiple different neurological and psychiatric illnesses and can be refractory to existing treatments. Auditory hallucinations and visual hallucinations are found across diagnostic categories of psychotic disorders (schizophrenia, schizoaffective, bipolar disorder). Despite visual hallucinations being approximately half as frequent as auditory hallucinations, they almost always co-occur with auditory hallucinations, and are linked to a more severe psychopathological profile. Auditory and visual hallucinations at baseline also predict higher disability, risk of relapse and duration of psychosis after 1 and 2 years, especially when they occur in combination. Using a newly validated technique termed lesion network mapping, researchers demonstrated that focal brain lesions connected to the right superior temporal sulcus (rSTS) plays a causal role in the development of hallucinations. The rSTS receives convergent somatosensory, auditory, and visual inputs, and is regarded as a site for multimodal sensory integration. Here the investigators aim to answer the question whether noninvasive brain stimulation when optimally targeted to the rSTS can improve brain activity, sensory integration, and hallucinations.
Amyotrophic lateral sclerosis (ALS) has been traditionally considered incurable and untreatable. But starting in the 1990s with the introduction of Riluzole, therapies are being discovered and ultimately approved for slowing disease progression. Many pharmaceutical companies continue to seek new therapeutic approaches. One critical aspect of all clinical trials is the need track to progression sensitively to identify the impact of therapy. Tools to track ALS progression must be convenient, objective, require minimal training, be easily standardized, cost-efficient, and have the potential to be applied effectively at home. There has been a push to identify accurate, objective biomarkers of ALS progression. In this study, the investigators propose to use Electrical impedance myography (EIM) to evaluate the progression of the disease. Work has shown that the EIM 50 kilohertz (kHz) phase value from one or more muscles, followed sequentially, can serve as an effective overall biomarker for assessing the rate of ALS progression for a single person.
The investigators are trying to learn more about the cause of kidney diseases such as Focal Segmental Glomerulosclerosis (FSGS) and Nephrotic syndrome by studying genetics. The investigators are interested in discovering which genes play a role in causing a predisposition to FSGS/NS. The investigators also want to learn why FSGS/NS can run in families. Participation in our study involves a saliva sample and a urine sample that you can give from home. There is no cost to participate. All information is kept private and confidential. The investigators also like to include healthy volunteers (parents, spouses) if interested/available but of course this is completely optional.
Using indocyanine green (ICG) lymphography and lymphoscintigraphy with SPECT/CT imaging, the aim is to evaluate the anatomy of the lymphatic system pathway in two separate populations: healthy female volunteers and women with a history of breast cancer who did not develop lymphedema.
The investigators aim is to compare outcomes between an angled-tip guidewire and a straight-tip guidewire in cannulation of the common bile duct during ERCP. This is a randomized, controlled, single-blinded study. The primary outcome is success of cannulation and secondary outcomes are incidence of post-ERCP pancreatitis, procedure duration, and rate of complication between the angled wire and straight wire.
This is a randomized, double-blind, placebo-controlled trial to determine if administration of intravenous thiamine will lead to quicker resolution of acidosis in patients admitted to the hospital with diabetic ketoacidosis. The investigators will secondarily investigate whether thiamine improves cellular oxygen consumption, shortens intensive care unit (ICU) and hospital stay or decreases hospital resource utilization.
The purpose of this investigation is to evaluate how early biomarkers of infection and inflammation perform in identifying patients at risk for poor outcome in sepsis and septic shock.
The overall hypotheses of this project is that severe sepsis is associated with endothelial dysfunction; that endothelial dysfunction, in turn, is predictive of subsequent organ failure and death; and that protocolized resuscitation attenuates endothelial cell (EC) dysfunction and improves patient survival.
The purposes of the study are to 1) study alterations in the metabolomic profile of patients exposed to post-ischemic conditions and 2) study alterations in myocardial infarction size of patients exposed to post-ischemic conditioning.
Multiple agents have been studied to prevent radiocontrast nephropathy. One of these agents is N-Acetylcysteine. Previous trials to assess N-Acetylcysteine's efficacy in the prevention of contrast nephropathy have been promising. However, previous studies have limited applicability to the Emergency Department (ED) patient population for two reasons:
Many of the pretreatment strategies employed in these studies take several hours or even days to perform, which is not feasible in acutely ill ED patients.
Most of these studies were conducted in patients undergoing cardiac catheterization. This may be a very different population than patients in the ED undergoing abdominal or chest computed tomography.
The investigators wish to study the efficacy of N-acetylcysteine as an agent to prevent radiocontrast nephropathy in ED patients undergoing computerized tomography. The investigators propose a randomized, double-blind, controlled trial comparing saline hydration plus N-acetylcysteine versus saline hydration alone. The hypothesis of this study is that N-acetylcysteine with normal saline will be more effective than saline alone in the prevention of radiocontrast nephropathy.
The overall hypotheses of this project is that Near Infrared Spectroscopy (NIRS) can be used to identify morbidity, mortality, and resource utilization in patients with sepsis and septic shock.
The goal of this study is to compare the characteristics of echocardiography and different monitoring devices in shock patients, the relationship of device parameters to biomarkers associated with shock, and determine if these any of these add clinical utility when predicting the cause of shock. We will perform a prospective, observational study of patients found to have shock physiology in the ED and follow them to determine the final shock category and ultimate outcomes.
The overall goal of this multicenter project is to characterize the expected normal range of Peripheral IntraVenous Volume Analysis (PIVA) values during a euvolemic state, and how those ranges may be altered by comorbidities; the relationship between PIVA and intravenous volume administration during resuscitation of infected patients with presumed hypovolemia; and, the relationship between PIVA and volume decreases during diuresis in acute heart failure patients with hypervolemia.
The purpose of this study is to perform a pilot study to assess the potential use of Bevacizumab (a vascular endothelial growth factor (VEGF) inhibitor) in sepsis.
This research study is a Phase II clinical trial. Phase II clinical trials test the effectiveness of an investigational drug, which is cisplatin in this trial, to learn how well it works in treating a specific cancer. "Investigational" means that cisplatin is still being studied for use in this setting and that research doctors are trying to find out more about it-in this case, how effective cisplatin is for treating breast cancer in BRCA mutation carriers. It also means that the FDA has not yet approved cisplatin for your type of cancer. Cisplatin has been approved by the FDA for treatment of other cancers.
The purpose of this study is to evaluate cisplatin, a chemotherapy drug that has been shown to be active in the treatment of women with breast cancer and a BRCA mutation. In this study, we are comparing cisplatin to the standard chemotherapy, doxorubicin and cyclophosphamide ("AC") that you might receive if you did not participate in this study.
A multicenter, randomized, parallel-group, placebo-controlled, double-blind, Phase 1/2a clinical study to investigate the safety, tolerability, immunogenicity and exploratory efficacy of a vaccine regimen consisting of an Ad26.Mos4.HIV prime and a boost with Modified Vaccinia Ankara (MVA)-BN-HIV in combination with broadly neutralizing antibodies (bNAb) PGT121, PGDM1400, and VRC07-523LS in human immunodeficiency virus type 1 (HIV-1)-infected study participants on suppressive anti-retroviral therapy (ART).
This research study is for patients with metastatic breast cancer.
Metastatic means that the cancer has spread beyond the breast. In addition, through genetic testing of the blood or tumor, an altered gene has been found that suggests the tumor may not be able to repair its genetic material (DNA) when it becomes damaged.
This aspect of the cancer may cause it to be more sensitive - that is, more effectively killed by certain types of drugs such as the study agent being evaluated in this trial, Olaparib.
Olaparib is a type of drug known as a PARP inhibitor. Some types of breast cancer and ovarian cancer share some basic features that make them sensitive to similar treatments. Information from those other research studies suggests that this drug may help to treat metastatic breast cancer.
This study will evaluate whether olaparib is effective in breast cancer patients whose tumor has a mutation in one of the other genes that function with BRCA1 and BRCA2 to repair damaged DNA .This mutation may have been inherited from a parent, or may have developed only in the tumor.
This study will also evaluate whether olaparib is effective in breast cancer patients whose tumor has a mutation in BRCA1 or BRCA2 that was acquired by the tumor, but not inherited.
There is an increased risk of diastolic heart failure in post menopausal women. Estrogen plays a positive role in regulating molecular pathways in heart remodeling. Such pathways may work through purinergic signaling and its downstream effects on the heart's mitochondrial metabolism and angiogenic response to stress. Loss of estrogen functionality in post menopausal women may account for the increased risk of diastolic heart failure. The investigators will explore said pathways using cardiac tissue obtained from patients undergoing cardiac surgery.
The goal of this observational study is to learn the how to determine the mean arterial pressure(MAP) or blood pressure level to be maintained during non-cardiac surgery for optimal brain health in patients above the age of 60 undergoing major non-cardiac surgery. The main question[s] it aims to answer are:
Is there a way to tailor the blood pressure to be maintained in such patients during surgery for optimal brain health using non-invasive monitors that check the brains electrical activity, the electroencephalogram(EEG) monitor, and the brain's blood oxygen levels, the cerebral oximetry(CO) monitor?
How much does this optimal blood pressure level vary between patients?
Participants will be asked to:
Complete a questionnaire at the time they enroll into the study, as well as a daily questionnaire to help determine their level of thinking and brain health. This questionnaire will be administered by a member of the study team.
They will also have an EEG and CO monitoring sticker placed on their foreheads. This will be connected to a monitor that will collect this data just before, during, and after their surgery. The data collected through these monitors will help us with our study goals.
Primary high-risk human papillomavirus (HPV) testing has become first line screening for cervical cancer in high-income countries. The feasibility of this approach in low- and middle-income countries (LMICs) is less clear, as is the role of HPV testing among women living with human immunodeficiency virus (HIV). The proposed study seeks to evaluate the accuracy of cervical cancer screening algorithms using primary HPV testing followed by various forms of visual evaluation, including visual inspection with acetic acid (VIA), colposcopy and automated visual evaluation (AVE) for the detection of high-grade cervical dysplasia, using histology as the gold standard. We will validate the AmpFire Assay for HPV self-sampling in our setting. We will determine safe screening intervals in women living with HIV (WLHIV) in an HPV-based cervical cancer screening program and compare triage strategies for positive HPV results at WHO recommended screening intervals for WLHIV. We also seek to understand in-depth the attitudes, acceptability and preferences regarding cervical cancer screening, HPV testing, and self-sampling, for women in Botswana through interviews of a sub-set of women recruited for the cervical cancer screening study. Finally, we will analyze the cost of two-stage cervical cancer screening algorithms using high-risk HPV testing in Botswana.
This is a prospective cohort study of older patients receiving implantable cardioverter-defibrillators. The purpose of the TRACER-ICD study is to conduct a prospective cohort investigation with the goal of 500 patients age >65 receiving new primary prevention implantable cardioverter-defibrillators (ICDs). Patients will be followed quarterly for 18 months with interviews, electronic record review, and remote monitoring to characterize clinical and functional trajectories following device implantation, with permission for extended electronic follow-up for up to 10 years (Aim 1). This cohort will support validation and refinement of an established model for predicting personalized outcome profiles for ICD therapies and death (Aim 2). Lastly, we will combine electronic record review with semi-structured interviews with patients and physicians to evaluate physician and patient experiences with a prototype individualized shared decision-making (SDM) tool (Aim 3).
The investigators will assess the feasibility and validity of esophageal pressure measurements during one-lung ventilation in the lateral position for surgery by comparing to lung collapse estimated from electrical impedance tomography during a PEEP trial.
This research study is evaluating the use of Cardiac Magnetic Resonance Imaging (CMR) as a method of detecting early signs of damage to the heart that can be associated with anthracycline-based chemotherapy for the treatment of breast cancer.
Patients undergoing general anesthesia require mechanical ventilation (artificial delivery of air and oxygen to their lungs). It is well known that during mechanical ventilation so called atelectasis formation occurs. This is a condition characterized by partial or complete collapse of lung tissue that can result in a reduction in oxygen uptake through the lung. A known risk factor for atelectasis formation during mechanical ventilation is the utilization of high oxygen concentration as the oxygen molecules are absorbed in the lung, which then can lead to collapse of the tissue. Despite the proven association standard operating procedure at the end of anesthesia still requires utilization of 100% oxygen. Its justification is the goal to ensure sufficient oxygenation throughout the extubation phase. However, clinical observation doesn't show a lack of oxygenation in this phase but the patient is still exposed to the risk of atelectasis formation.
This study aims to investigate the hypothesis of whether the utilization of reduced oxygen concentration before extubation (70% compared to 100%) reduces atelectasis formation. Patients who participate in this study are randomly (i.e. by chance) assigned to either the control group receiving standard care (100% oxygen at the end of anesthesia), or the intervention group receiving 70% oxygen. Of note, this is still 3 times as much as when breathing "standard" room air, which has 21% oxygen. During the intervention, parameters such as the oxygen content in the blood (oxygen saturation, SpO2), heart rate and blood pressure are recorded and atelectasis formation is measured using a technique called electrical impedance tomography (EIT). EIT measurements are performed at designated timepoints during the procedure. Anesthesia care providers are asked to document procedural, patient and ventilator data in a questionnaire. Secondary outcomes are the homogeneity and distribution of air measured with EIT, as well as some clinical outcomes including post-extubation desaturation (<90% SpO2), incidence of re-intubation or non-invasive ventilation and the Post-anesthesia Care Unit (PACU) length of stay.
To determine if Mind Body Syndrome (MBS) therapy will reduce or eliminate pain in patients suffering from chronic pain syndromes without organic etiology.
The purpose of this study is to determine whether administration of a pectoral nerve blocks (Pecs I and II) with 0.25% bupivacaine are more effective as compared to placebo to provide analgesia for cardiac implantable electronic device (CIED) placement in cardiac electrophysiology lab
The purpose of this protocol is to investigate the effect of treatment with the study drug Liraglutide, a GLP-1 receptor agonist, on centers of the brain that control appetite and food intake.
The primary purpose of this phase 2a study is to compare the efficacy of abrocitinib to placebo in improving severe fatigue in non-hospitalized adults with symptomatic Post-COVID Condition (PCC) (also called Long COVID). We are also interested in learning if abrocitinib is effective in improving overall health status in people suffering from severe fatigue from PCC. Eligible participants with a confirmed history of COVID19 infection who also have PCC according to the World Health Organization definition, will be randomized to receive abrocitinib at a dose of 50 mg, 100 mg, or placebo by mouth daily for 12 weeks (84 days).
This research study is studying a cancer vaccine called Dendritic Cell/AML Fusion vaccine (DC/AML vaccine) as a possible treatment for Acute Myelogenous Leukemia (AML).
The interventions involved in this study are:
-Dendritic Cell/AML Fusion vaccine (DC/AML vaccine)
Anesthesia is crucial during upper GI endoscopy in order to improve the procedural conditions for the interventionist, increase the quality of examination and alleviate patient discomfort. However, sedation during endoscopy carries a serious risk of blood oxygen desaturation.
This study aims to investigate the hypothesis if the application of high-flow nasal oxygen (HFNO) during high-risk gastroscopy reduces the risk of blood oxygen levels to drop below a defined threshold. Enrolled patients will be randomly assigned to either the control group, receiving standard care during endoscopy, or the intervention group, receiving HFNO therapy during the procedure. Throughout the intervention, vital parameters will be recorded. Care providers will be asked to answer a questionnaire that specifically evaluates the effect of HFNO on patient safety and the procedure.

Scope maneuverability
Tool compatibility
Suction
Lavage
Safety
Image quality
Participants will undergo bronchoscopy with single use bronchoscopes.
The purpose of the project is to perform an RCT comparing patient satisfaction and outcome with or without the use of an expert panel. The purpose is also to create a registry to compare the effectiveness of decompression alone versus decompression with fusion for patients with degenerative grade I spondylolisthesis and symptomatic lumbar spinal stenosis. Primary analysis will focus on the patients' improvement from baseline patient-reported outcome questionnaires.
In addition, the SLIP II registry aims to (i) develop an algorithm which could identify cases in which surgical experts are likely to recommend one treatment (i.e. >80% of experts recommend one form of treatment) and (ii) develop a radiology-based machine learning algorithm that would prospectively classify patients as either 'stable' or 'unstable.'
In addition to patient reported outcomes, step counts will be collected in order to determine the correlation of step count with patient-reported outcomes (ODI and EQ-5D) and the need for re-operation.
This registry portion of the study aims to prospectively collect comparative data for these patients treated with either decompression alone or decompression with fusion.
This study will compare stereotactic body radiation therapy (SBRT) to trans-arterial chemoembolization (TACE) as a bridging strategy for patients with HCC undergoing liver transplantation. We propose that SBRT will be associated with longer time intervals between initial treatment and the need for retreatment, compared to TACE, as a "bridge" to liver transplantation in subjects with HCC.
High-dose interleukin 2 (Proleukin, Novartis) (IL-2) is approved by the U.S Food and Drug Administration (FDA) for the treatment of metastatic kidney cancer and is a standard treatment of this disease. At the present time, IL-2 is the only therapy for kidney cancer that can produce a remission of disease that lasts after treatment is completed. However, most patients who receive IL-2 do not benefit and all patients experience potentially dangerous side effects.
Recent research has suggested that certain patients may respond better to IL-2 than others. The Cytokine Working Group is currently conducting a clinical trial that aims to identify and confirm this research and narrow the application of IL-2 to those patients most likely to benefit.
The objective of this study is to determine whether a new minimally invasive method for in vivo measurement of cortical bone tissue properties can identify those who are at risk for fragility fractures of the hip and radius. The investigators hypothesis is that women with fragility fractures of the hip and radius have altered cortical bone tissue properties compared to non-fracture controls independent of standard clinical tests, such as bone mineral density (BMD) by dual-energy x-ray absorptiometry (DXA).
The study is designed to investigate the impact of three nights of sleep restricted to 4 hours per night, on the processing and regulation of emotional information compared to Insomnia Disorder and control. The investigators will address and attempt to answer two questions.
(i) How do three nights of reduced sleep or a diagnosis of Insomnia Disorder affect the processing and regulation of emotional information compared to typical, undisturbed sleep? (ii) What overlapping and distinct neural mechanisms are engaged and associated with behavioral effects when attempting to process and regulate emotions in a sleep restricted state or with a clinical diagnosis of Insomnia Disorder? This study will investigate sleep's role in emotion processing and regulation. The findings will help further understanding of the role of sleep in healthy emotional functioning.
The primary aim of the study is to assess the mobility dose in neurocritical care patients with ischemic stroke or intracranial hemorrhage and its effects on discharge disposition and patient outcomes. The investigators hypothesize that patients' mobilization dose in the intensive care unit (ICU) predicts discharge disposition, 90 day Barthel Index and other outcomes like muscle wasting (expressed as decrease in rectus femoris cross sectional area (RF-CSA) in the paretic and non-paretic limb measured by bedside ultrasound), and ICU length of stay (LOS).
This study is being done to see if nitrous oxide during vasectomy decreases pain and anxiety, and also assess whether patients have better satisfaction when they control their own level of nitrous oxide during the procedure. If we find that patients experience less pain or anxiety with nitrous oxide, it could be suggested that self-adjusted nitrous oxide (SANO) may be a useful tool for improving experience of care during vasectomy.
The goal of this research study is to determine whether hormonal therapies used early in the course of prostate cancer could increase the amount of Prostate-Specific Membrane Antigen (PSMA) as detected by PET/CT scans for participants with recurrent prostate cancer. This study will measure PSMA levels using standard PET/CT scans and participants will receive standard-of-care androgen receptor antagonist monotherapy.
The names of the treatment interventions involved in this study are:
Androgen receptor antagonist monotherapy.
PSMA PET/CT scan
It is expected that about 15 people will take part in this research study.
Participation in this research study is expected to last about 4 weeks.
