This project proposes to conduct the first study of the predictive utility of olfactory hedonic measurement for targeted psychosocial rehabilitation in schizophrenia. The information gathered from the project is of considerable public health relevance, in that, through simple, reliable olfactory assessment, it will provide knowledge about which individuals are most likely to benefit from these psychosocial interventions. Such information is crucial for tailoring existing interventions and developing new approaches to optimize outcomes in schizophrenia.
In this pilot study, the investigators aim to assess feasibility of subject identification and data collection, including specimen processing, as well as the rate of enrollment for a future, larger study of the effect of empiric antibiotics for all patients with advanced cirrhosis admitted to the hospital without an existing indication for new antibiotic use. Specifically, the investigators will assess the incidence of infection after the time of enrollment and associated outcomes. Subjects will be randomly assigned to receive antibiotics vs placebo.
Acute hypoxemia is common and deadly in resource variable settings. While studies in high income countries (HICs) have indicated a possible benefit to high flow oxygen as compared with standard flow oxygen, rigorous studies in low or lower middle income countries (LMICs) have not been performed. Studies in sepsis have demonstrated that interventions that improve outcomes in one context may actually be neutral or harmful in a different context.
The goal of this study is to test whether high flow oxygen results in better outcomes for hypoxemic adult patients, as compared with standard flow oxygen, in five LMIC hospitals. The main questions it aims to answer are:
For hypoxemic adults in these LMIC study settings, does high flow oxygen or standard flow oxygen result in lower mortality?
What are the facilitators and barriers to using high flow oxygen in these settings?
Does high flow or standard flow oxygen use more oxygen?
Participants will be randomized to receive either high flow oxygen through a large nasal cannula, or to receive standard flow oxygen, through nasal cannulas, face masks, or non-rebreather masks. Researchers will compare the outcomes for the two groups, to see if one group of patients has better outcomes than the other.
The study will also examine how much oxygen is used by the two patient groups, as well as other factors relevant to the feasibility of implementation of high flow oxygen in these sites.
The purpose of this pilot study is to assess the feasibility of delivering a multicomponent prehabilitation and measuring patient-centered outcomes in older adults undergoing major surgery.
In the PATHFINDER 2 trial, the study investigators will test the intraoperative EEG-guided multimodal general anesthesia (MMGA) management strategy in combination with a postoperative protocolized analgesic approach to:
reduce the incidence of perioperative neurocognitive dysfunction in cardiac surgical patients
ensure hemodynamic stability and decrease use of vasopressors in the operating rooms
reduce pain and opioid consumption postoperatively
The main purpose of this study is to learn about the influence of two different behavioral interventions (lasting 8 weeks) involving sleep for lowering blood pressure, and to study the mechanisms involved. There is research evidence that healthy sleep promotes heart-health and may decrease blood pressure, and that sensitivity to insufficient or disrupted sleep may be influenced by sex. This research will compare two interventions that are each designed to improve sleep health, and will investigate sex differences in response. The project includes 3 in-hospital stays with biological measurements to evaluate the underlying mechanisms associated with the effectiveness of two different blood pressure lowering behavioral interventions.
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.
The main purpose of this study is to learn how transcranial magnetic stimulation (TMS) helps improve negative symptoms of schizophrenia. These 'negative symptoms' include anhedonia (the inability to enjoy things), low motivation, and decreased facial expression.
TMS is a noninvasive way of stimulating the brain. TMS uses a magnetic field to cause changes in activity in the brain. The magnetic field is produced by a coil that is held next to the scalp. In this study we will be stimulating the brain to learn more about how TMS may improve these symptoms from schizophrenia.
The aim of this study is to assess the feasibility and acceptability (e.g., enrollment, adherence, retention, acceptability of procedures and interventions) of a pilot factorial study design that will help elucidate components of mind-body exercise interventions. The study involves completing a walking program, a mindful attention program, a walking program that includes mindful attention, or no program at all. A "pilot" study is a smaller study that helps researchers to understand whether the study design can be carried out and what participants think about the study.
The OPTIMIZE Trial compares whether iDose dashboard-driven infliximab dosing (iDose-driven dosing) is more effective and safer than standard infliximab dosing for inducing and maintaining disease remission in moderately to severely active CD.
The study is being conducted to learn why some patients with Benign Prostatic Hyperplasia (BPH) do not respond to a commonly used treatment drug, Finasteride. The hope is to find ways to predict which patients will not respond to Finasteride so that, in the future, these patients can be identified prior to offering this treatment and they can be offered alternative treatment strategies in its place. The aim is to see if noninvasive techniques such as MRI can detect inflammation of the prostate to assist with early detection of those who will and who will not respond to Finasteride.
Live donor kidney transplantation (LDKT) offers the most optimal survival and quality of life benefit for those with late-stage chronic kidney disease. However, minorities, especially blacks, are much less likely to receive LDKT than whites. Given the shortage of deceased donor organs, interventions expanding access to LDKT are needed, particularly for minority patients. House Calls (HC), an educational intervention developed by this study's PI has been shown to be an effective program for raising rates of live donation, especially for black patients. While the HC program has shown outstanding results, participant feedback suggested that follow-up may provide even more benefits. Previous research suggests that peer mentorship (PM) from former or current patients with ESRD may be effective in raising rates of living donation. As such, peer mentorship programs may act as an effective follow-up for HC participants. This study will examine the impact of the HC intervention combined with the peer mentorship program of the National Kidney Foundation on rates of live donor kidney transplantation.
Mania is a core symptom of bipolar disorder involving periods of euphoria. Decreased inhibitory control, increased risk-taking behaviors, and aberrant reward processing are some of the more recognized symptoms of bipolar disorder and are included in the diagnostic criteria for mania. Current drug therapies for mania are frequently intolerable, ineffective, and carry significant risk for side effects. Presently there are no neurobiologically informed therapies that treat or prevent mania. However, using a newly validated technique termed lesion network mapping, researchers demonstrated that focal brain lesions having a causal role in the development of mania in people without a psychiatric history can occur in different brain locations, such as the right orbitofrontal cortex (OFC), right dorsolateral prefrontal cortex (DLPFC), and right inferior temporal gyrus (ITG). This lesion network evidence converges with existing cross-sectional and longitudinal observations in bipolar mania that have identified specific disruptions in network communication between the amygdala and ventro-lateral prefrontal cortex. The OFC is associated with inhibitory control, risk-taking behavior, and reward learning which are major components of bipolar mania. Thus, the association between OFC with mania symptoms, inhibitory control, risk-taking behavior, and reward processing suggests that this region could be targeted using non-invasive brain stimulation.
This is a randomized, pilot interventional study in participants with visual field deficit (VFD) caused by cortical lesion. Damage to the primary visual cortex (V1) causes a contra-lesional, homonymous loss of conscious vision termed hemianopsia, the loss of one half of the visual field. The goal of this project is to elaborate and refine a rehabilitation protocol for VFD participants. It is hypothesized that visual restoration training using moving stimuli coupled with noninvasive current stimulation on the visual cortex will promote and speed up recovery of visual abilities within the blind field in VFD participants. Moreover, it is expected that visual recovery positively correlates with reduction of the blind field, as measured with traditional visual perimetry: the Humphrey visual field test. Finally, although results will vary among participants depending on the extension and severity of the cortical lesion, it is expected that a bigger increase in neural response to moving stimuli in the blind visual field in cortical motion area, for those participants who will show the largest behavioral improvement after training. The overarching goals for the study are as follows: Group 1 will test the basic effects of transcranial random noise stimulation (tRNS) coupled with visual training in stroke cohorts, including (i) both chronic and subacute VFD stroke participant, and (ii) longitudinal testing up to 6 months post-treatment. Group 2 will examine the effects of tRNS alone, without visual training, also including chronic and subacute VFD stroke participants and longitudinal testing.
To further understand the impact of acute sleep deprivation and recovery sleep on the processing of emotional information the investigators will address and attempt to answer three questions, (i) how both undisturbed sleep and sleep deprivation affect the processing and retrieval of emotional information, (ii) what neural and psychophysiological mechanisms are associated with these behavioral effects, and (iii) to explore the ability of recovery sleep to reverse the effects of sleep deprivation. Together, these studies will provide a greater breadth and depth of knowledge concerning sleep's role in emotion processing and regulation. Given the growing societal tendency to view sleep as unproductive-foregoing it to lengthen work days and increase social opportunities- such knowledge would be of practical importance for understanding the role of sleep in healthy emotional functioning, particular for individuals experiencing periods of increased stress and emotional distress (e.g., new parents, hospital staff, or combat troops).
To further understanding of the relationship between sleep and memory the investigators will address and attempt to answer three questions, (1) how memories evolve across wake and sleep, (2) how different aspects of this memory evolution are reflected both behaviorally and in the EEG signal, and (3) what stages and features of sleep affect memory evolution. Together, these studies will provide a greater breadth and depth of knowledge concerning sleep's role in memory consolidation. Such knowledge would be of practical importance for educational practices, whether in schools, on the job, or in the military, and would also provide valuable information to the fields of sleep medicine and psychiatry, where interactions between sleep disorders and cognitive functioning are of great importance.
The goal of this study to evaluate whether eliminating the use of non-depolarizing neuromuscular blocking agents (NMBA) for maintenance of general anesthesia reduces postoperative pulmonary complications in higher risk patients.
The aim of this study is to explore the relationship between cortical hyperexcitability, abnormalities of brain network function, and cognitive dysfunction in human patients with AD and whether administration of the antiepileptic medication levetiracetam (LEV) normalizes these measures and improves cognition.
This is a randomized controlled trial with a mixed method design to determine the impact of coaching on self-perceived medical errors, burnout, and resilience. The study team developed a novel coaching curriculum based in principles of positive psychology and self-reflection with the hypothesis that the coaching intervention will lead to decreased medical errors, decreased burnout, and increased resilience in trainee and faculty participants. Resident and fellow trainees as well as faculty members were recruited across departments and randomized to coaching or control. Faculty in the coaching arm were trained in coaching techniques and paired with a trainee coachee. Survey results as well as focus groups will be used to analyze the impact of the coaching program as compared to standard mentorship (control).
The main goal of this study is to determine whether there is a relationship between fremanezumab's ability to prevent migraine and improved sleep quality in migraine patients (fremanezumab is a FDA-approved humanized CGRP monoclonal antibody for the treatment of migraine).
This is a within-person study design that examines treatment effects (changes) using high-resolution assessments. To complete the study, each participant will be observed using daily assessments of migraine and sleep outcomes before treatment (baseline: 0 to 30 days), and at 1, 2, and 3 months after treatment (injection 1: days 31-60, injection 2: days 61-90, injection 3: days 91-120). In essence, this creates an interrupted time-series design where repeated interventions are introduced at fixed intervals.
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 study aims to evaluate the effectiveness of offering reimbursement for living donor lost wages on the rate of live donor kidney transplantation.
Brown fat is a type of fat, found in both children and adults, which can produce heat and regulate the body's metabolism and energy use. White fat is the more common type of fat which is used to store extra calories. Understanding more about differences between brown and white fat may allow us to develop new approaches to improve the body's metabolism.
The long-term goal of this proposal is to provide a pre-treatment evaluation that can assist in the rational selection of patients to undergo appropriate and definitive therapy for prostate cancer. In so doing, it may be possible to further improve the numbers and percentage of cancer patients who receive effective therapy that will cure the disease and maximize their quality of life following therapy.

Aim 3: To evaluate the accuracy of MRI in grading prostate cancer.
The investigators are studying the use of an advanced magnetic resonance imaging (MRI) technique for measuring blood flow into brain tumors. This technique does not use radioactive tracers, and it can provide high quality images that can be obtained in a standard MRI scanner.
This projects studies the role of tai chi exercise and wearable fitness trackers to promote physical activity in acute coronary syndrome (ACS) survivors.
The main purpose of this study is to test the safety of the dendritic cell/tumor fusion study vaccine in combination with a laboratory-made agent called Granulocyte Macrophage Colony Stimulating Factor (GM-CSF). Another purpose is to determine the type and severity of any side effects associated with this study vaccine. GM-CSF is similar to a substance in the body that stimulates the production of white blood cells. To create the study vaccine, cells will be removed from the participants tumor and fused with dendritic cells which are obtained from the participants blood. Dendritic cells are responsible for immune responses to "foreign" substances that enter the body. Animal studies have shown that these fused cells can stimulate powerful anti-tumor responses.

The purpose of this study is to determine if analysis of DNA and protein material found in urine will be useful in the detection of urothelial cancer of the bladder and kidney. This analysis may be helpful to determine if how a particular cancer will act regarding remission and recurrence
Chronic pain syndromes without identified organic etiology remain a challenge for physicians. Many syndromes, including back pain, are believed to have potential underlying psychological etiology; however, the exact link remains elusive. The goal of this study is to determine if mind body therapies can help people suffering from chronic back pain. The study is a randomized, partially blinded trial examining the effectiveness of Mind Body Syndrome Therapy (MBST) in reducing disability from back pain and alleviating back pain. The investigators will secondarily investigate whether MBST can improve participant quality of life and reduce the need for pain-related hospitalization. The design of the this study consists of 3 arms with one being the intervention (MBST), one being usual care, and one being a second mind-body intervention (active control). This education program consists of a series of personal interviews and group and/or individualized lectures/sessions. Participants will also be provided reading material to study during the intervention period, and asked to continue their usual care while going through the MBST program.
The goal of this study is to determine if a mind-body intervention can help people suffering from chronic back pain. The study is a randomized, partially blinded trial examining the effectiveness of a mind body intervention in reducing disability from back pain and alleviating back pain in participants as compared to usual care and an active control (second mind body intervention). The investigators will secondarily investigate whether the intervention alleviates anxiety related to the pain and other quality of life parameters.
The enhanced recovery after surgery (ERAS) pathway is a well-described evidence-based protocol to optimize patient post-operative recovery. Patients undergoing cesarean hysterectomies are a unique surgical population. These procedures are most commonly performed for patients with placenta accreta spectrum or severe postpartum hemorrhage. In recent studies examining the effectiveness of the ERAS pathway, post-operative cesarean patients experienced decreased average inpatient opioid exposure without an increase in pain scores, early mobilization and nutrition targets without increases in adverse outcomes after program implementation. Post-operative hysterectomy patients with gynecologic indications experienced shorter lengths of stay and decreased opioid consumption. Additionally, patients have significantly higher satisfaction scores. The investigators suspect that this population may also benefit similarly.
This research is a pre- and post- study to assess and describe surgical outcomes and parameters surrounding patients' post-operative recovery and experience before and after the ERAS pathway is implemented at a high volume placenta accreta spectrum Center of Excellence.
This prospective, open-label, randomized-controlled trial is designed to evaluate the use of the Traxi panniculus retractor-- a commercially available Class I FDA-exempt device will improve surgical outcomes, cardiopulmonary function, and provider/patient satisfaction in morbidly obese women undergoing cesarean delivery.
The participant is invited to take part in this study because they have chronic Graft versus Host Disease (cGVHD) that is not responding to standard treatment with steroids. This research study is a way of gaining new knowledge about the treatment of patients with cGVHD. This research study is evaluating a drug called abatacept.
Abatacept is a drug that alters and suppresses the immune system. Abatacept is approved by the Food and Drug Administration (FDA) for the treatment of moderate to severe active rheumatoid arthritis in adults and of severe juvenile idiopathic arthritis (JIA) in patients who have failed prior therapy with disease-modifying anti-rheumatic drugs (DMARDs). These are autoimmune conditions, ie caused by an overactive immune system that attacks normal tissues and organs. It is currently being tested in a variety of other autoimmune conditions. In this case it is considered experimental.
cGVHD is caused by the donor cells attacking various organs of the recipient. The investigators try to minimize this immune attack by using corticosteroids such as prednisone. In severe cases prednisone is not sufficient and other immunosuppressive medications are used in addition in order to more efficiently control cGVHD and to limit the dose and consequently the multiple side-effects of corticosteroids. This study is being done to determine if the use of abatacept is safe in patients with cGVHD and if it can facilitate a better control of cGVHD.
During this study the participants will be evaluated for side effects from the treatment with abatacept, and for response of the cGVHD to the treatment. There will be two groups of participants in the study. The first group will be treated at a relatively low dose of abatacept. If this is found to be safe then the second group will be treated at a higher dose. Three to four tablespoons of blood will be drawn at every 2 week visit in order to determine your blood counts, kidney and liver function. Some of the blood will be used in a research lab in order to study measures of your immune system and how they might be affected by the treatment.
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.
This is a developmental project with two phases. The first phase will adapt an existing web-based intervention to incorporate mind-body exercises to develop a multi-modal intervention to promote physical activity in patients with COPD and HF. The second phase will pilot test this new intervention in a longitudinal study (subjects randomized to intervention or usual care).
This study evaluates the effect of hypertonic saline 23.4% injection in fistulas or sinus tracts in adult patients with hidradenitis suppurativa.
The aim of this study is to assess the capability of a modified under bed weighing scale (contact-free unconstrained respiratory monitor, BSS) to predict postoperative pulmonary complications in high-risk surgical patients.
The study is designed to test the hypothesis that abnormal breathing measured by a modified under bed weighing scale predicts postoperative pulmonary complications within 7 days after surgery.
This study will examine the safety of clofarabine, TLI and ATG as a reduced conditioning regimen prior to allogeneic transplantation. The impact of the conditioning regimen on the presence of the circulating regulatory as compared to activated T cell populations will be assessed.The recovery of DC populations post-transplant will be examined, along with the effect of the regimen on disease free and overall survival.
The purpose of this pilot study is to test the study protocol for an RCT comparing IVF outcomes between day 3 and day 5 embryo transfer in patients with five or fewer embryos in a fresh embryo transfer in vitro fertilization (IVF) cycle. Information derived from this RCTwould allow us to maximize the chances of success for these patients undergoing IVF.
Despite growing evidence showing benefit (in both clinical and cost standpoints), only a small percentage of COPD patients with chronic hypercapnic respiratory failure are managed with nocturnal ventilatory support. There is uncertainty of the value of aggressive nocturnal ventilation, especially polysomnographic estimation of therapy and home transcutaneous CO2 tracking.
The driving goal behind this project is to develop and implement a streamlined and comprehensive program for nocturnal ventilator management of patients with advanced, hypercapnic COPD.
This is a pilot study evaluating the feasibility and acceptability of a non-pharmacological, mind-body intervention to improve sleep quality, including a preliminary evaluation of neurophysiological signals. The study involves 4 weeks of guided mind-body practice at home using a smartphone app during bedtime and pre/post in-lab sleep study visits.
The purpose of this study is to investigate whether speed-dependent measures of gait can be identified in patients with neurological conditions that affect gait, particularly in subjects with parkinsonian disorders.
This research study is evaluating the effect (good and bad) of a dendritic cell/tumor fusion vaccine in combination with the laboratory made agents GM-CSF and imiquimod on the participants immune system. Another purpose of this study is to determine the type and severity of any side effects associated with this new study vaccine. We will also be evaluating what effect the vaccine has on the participants cancer. Dendritic cell vaccines have already been tested in clinical trials involving participants with many different types of cancer. Dendritic cells are powerful immune-stimulating cells that are normally found in small amounts in the body and are responsible for immune responses against "foreign" substances that enter the body.
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.
