Clinical Trials

Description

Irritable bowel syndrome (IBS) is a chronic functional gastrointestinal disorder that generates a significant health care burden and is the most commonly diagnosed gastrointestinal condition. Nearly 12% of all patients in the United States seek medical care in primary care practice for IBS and it accounts for 3.1 million ambulatory care visits and 5.9 million prescriptions annually.

The pathophysiology of IBS is distinctly broad compared to other gastrointestinal conditions and includes abnormalities involving motility, visceral sensation, brain-gut interaction, and distress. Though patients with IBS often have a heterogeneous symptom profile, the predominant theme is the presence of abdominal pain or discomfort that is usually relieved by defecation. Host factors such as genetics, immune function, and psychological status, as well as environmental factors such as stress, recent infection, or treatment with antibiotics, could predispose to the development of chronic IBS symptoms. Due to a myriad of contributing factors, a single cause of IBS remains enigmatic. Despite the urgent need to develop better therapies, the high range of placebo response has made clinical trials challenging, ranging from 16.0 to 71.4% with a population-weighted average of 40.2%.

Recent studies have also shown alterations in gut immune response, and a disrupted intestinal and colonic microbiome in association with IBS. The current working hypothesis is that abnormal microbiota activate mucosal innate immune responses, which increase epithelial permeability, activate nociceptive sensory pathways, and dysregulate the enteric nervous system. Targeting the microbiota and gastrointestinal tract with live organisms is a promising approach, yet previous trials have yielded limited success due to empiric strain selection, small population size, and inadequate trial design to control for a high placebo response.

This protocol aims to assess the impact of a multi-strain consortia of 24 commensal organisms across 12 species with extensive strain-specific in vivo data, assessing a range of gastrointestinal symptoms without negatively altering the naive gut microbiota. High-throughput shotgun DNA sequencing will provide opportunity for '-omics'-based analyses of the gut microbiota, which can be augmented by the metabolite profiles resulting from total microbial activity in the gut. Since many of these metabolites are bioeffector molecules acting upon the host, such analysis can provide a direct measure of the consequences of microbial activity in the gut and provide a novel integrated data set for patients with IBS. Recruited subjects will also use a smart-phone application to report day to day gastrointestinal symptoms, a patient-centric hallmark of this chronic gut condition.

Probiotics are live microorganisms with a vast array of therapeutic potential for gastrointestinal disease. Several probiotics strains have shown beneficial outcomes in constipation-predominant IBS (IBS-C) patients, especially as an adjunct to conventional treatment. However, a number of controversial issues regarding the roles of probiotics in pathogenesis of IBS-C remain to be clarified, including precise mechanism of action.

This protocol aims to assess the impact of a mix of 24-beneficial strains on individual gastrointestinal symptoms specifically in a cohort of subjects with IBS-C or IBS-M.

Description

This double-blinded, placebo-control trial clinical trial aims to investigate the effect of IV oxytocin infusion on peri-operative opioid consumption following a minimally invasive hysterectomy under general anesthesia.

patients population will be women who have been scheduled for an elective, minimally invasive hysterectomy at Beth Israel Deaconness Medical Center.

We hypothesize that, compared to a placebo, exposure to intravenous (IV) oxytocin will reduce the amount of opioid consumption for women after a minimally invasive hysterectomy procedure.

Description

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.

Description

Our 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. Our 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.

Description

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.

Description

The purpose of the study is to determine the optimal surgical approach (ventral vs dorsal) for patients with multi-level cervical spondylotic myelopathy (CSM). There are no established guidelines for the management of patients with CSM, which represents the most common cause of spinal cord injury and dysfunction in the US and in the world.

This study aims to test the hypothesis that ventral surgery is associated with superior Short Form-36 physical component Score (SF-36 PCS) outcome at one year follow-up compared to dorsal approaches and that both ventral and dorsal surgery improve symptoms of spinal cord dysfunction measured using the modified Japanese Orthopedic Association Score (mJOA). A secondary hypothesis is that health resource utilization for ventral surgery, dorsal fusion, and laminoplasty surgery are different. A third hypothesis is that cervical sagittal balance post-operatively is a significant predictor of SF-36 PCS outcome.

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).

Description

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.

Description

This study aims to investigate the effect of a 15-minute meditation practice on sleep architecture and high-frequency Heart Rate Variability (HF-HRV), as well as cognitive performance after both a well-rested and sleep-deprived night.

Description

The objective of this study is to investigate a technique to monitor blood pressure in women undergoing cesarean delivery with suspected placenta accreta spectrum. To achieve this objective, the investigators plan to conduct a prospective, observational study with the following aims:

Specific Aim 1: Compare concordance between the systolic (SBP), diastolic (DBP), and mean arterial blood pressure (MAP) readings from the continuous non-invasive arterial blood pressure (CNAP) and IABP at several discrete points throughout the procedure

Specific Aim 2: Determine the feasibility of using CNAP to aid in decision making by examining the parameters of volume responsiveness and arterial elastance at several discrete points throughout the procedure.

The investigators hypothesize that the investigators can obtain similar blood pressure monitoring using CNAP as compared to the gold standard IABP in women undergoing cesarean delivery with suspected placenta accreta.

Description

Cesarean delivery has become the most common surgical procedure in the US. Non-steroidal anti-inflammatory drugs (NSAIDs) have been shown to improve the quality of post-cesarean analgesia and markedly reduce opioid consumption. The effect of NSAIDs on healthy volunteers results in inhibition of platelet aggregation and prolonged bleeding time. However, in the obstetric population, the presence and degree of platelet inhibition after NSAID exposure is less clear. The investigators plan to use Platelet Aggregometry and Thromboelastography (TEG) to evaluate the effect of ketorolac on platelets.

Description

This research study is a pilot study, which is the first time investigators are examining the effect of light alcohol consumption on sex hormones among postmenopausal women with estrogen receptor-positive (ER+) breast cancer taking an aromatase inhibitor

White grape juice

Description

The purpose of this research study is to determine the safety of CT-011 alone, as well as the combination of the Dendritic cell fusion vaccine and CT-011, after autologous stem cell transplantation (ASCT). We are also trying to find out what effect the combination has on the disease, including if it is more successful in preventing or delaying the disease from coming back, compared to treatment with autologous transplantation alone. ASCT is a standard therapy for multiple myeloma that is often successful in significantly decreasing the amount of cancer in the body. CT-011 is an investigational monoclonal antibody. Monoclonal antibodies are a type of drug given by infusion into a vein and are known to target specific cells (in this case, cells in the immune system). The dendritic cell fusion vaccine is an investigational agent that tries to help the immune system to recognize and fight against cancer cells. Unlike a standard vaccine that is used to prevent infections, cancer vaccines are being studied to see if they can fight cancers that are already in the body.

Description

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.

Description

This is a randomized, double-blind, placebo controlled study to investigate the effect of intravenous thiamine (vitamin B1) on lactate, cellular oxygen consumption, global oxygen consumption and biomarkers of neurologic injury after out-of-hospital cardiac arrest (OHCA). .

Description

This study is to evaluate whether thiamine can increase oxygen consumption and lower lactate in patients who initially survive an in-hospital cardiac arrest. Patients who are successfully resuscitated after an in-hospital cardiac arrest and who are on mechanical ventilation in the intensive care unit will be enrolled, and will get either thiamine or placebo. Their oxygen consumption and lactate will be measured at serial time points and compared between groups. The investigators' hypothesis is that thiamine will help restore the body's ability to metabolize oxygen normally (aerobic metabolism), leading to an increase in oxygen consumption and a decrease in lactate.

Description

Traditionally, the severity of a blockage (stenosis) in a coronary artery has been determined by visual angiographic assessment of the diameter of the artery at the level of a blockage compared to a normal healthy area of the same artery. With the advent of invasive physiological testing to assess coronary blood flow, multiple clinical trials have demonstrated a clinical benefit to a physiology-guided percutaneous coronary intervention (PCI) approach. However, despite this and the potential for significant variation in the interpretation of coronary artery stenosis severity by visual angiography alone to guide PCI, invasive physiologic indices remain significantly under-utilized.

The purpose of this study is to investigate the physiologic significance of coronary lesions deemed angiographically severe by visual estimation that are planned for PCI. The investigators plan to perform blinded physiologic assessment pre and post PCI. The primary aim of the study is to determine whether a subset of lesions visually estimated as severe by angiography treated with stent placement/PCI may in fact not be physiologically significant when assessed invasively, and thus PCI could safely be deferred in these patients. A secondary aim is to evaluate physiologic assessment post PCI to detect residual ischemia that could be utilized to optimize stent placement.

Description

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.

Description

This is a randomized, double-blind, placebo controlled study to investigate the effect of intravenous thiamine (vitamin B1) on renal function in septic shock.

Description

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.

Description

The primary objective of this study is to examine the safety and effectiveness of physician-modified endovascular grafts (PMEGs) for endovascular repair of complex aortic pathology in high-risk patients. The study is divided into three study arms based on the subject's aortic pathology: (1) Complex abdominal aortic aneurysm (AAA); (2) Thoracoabdominal aortic aneurysm; and (3) Aortic dissection.

Description

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).

Description

Acute pancreatitis (AP) represents a critical health concern nationwide, with estimated 274,000 admissions annually and at a cost of 2.6 billion dollars. Current treatment strategies for AP are limited to supportive care with fluid resuscitation, analgesia, nutrition and prevention of end organ damage. Abdominal pain is often the predominant symptom in patients with AP and is treated with analgesics. As there is currently no disease-specific medical treatment to change the natural history of pancreatitis, pain control remains central to the treatment of AP. Among the analgesics, opioids have been shown to be provide safe and effective pain control in patients with AP. Current literature shows that there is no difference in the risk of pancreatitis complications or clinically serious adverse events between opioids and other analgesia options. Among hospitalized AP patients, adequate pain control often requires the use of intravenous (IV) opiates in the first 24-48 hours, which can later be transitioned to oral (PO) opioids. While there are various methods of delivering opioid medications such as IV, PO, and transdermal to name a few, IV opioids are commonly administered, either on a scheduled and/or on an as needed (PRN) basis as directed by the attending physician. In contrast to the conventional, method of physician directed IV opioid delivery, patient-controlled analgesia (PCA) is a form of IV opioid medication delivery in which the patient can rapidly titrate the opioid dose to manage variable levels of pain. This modality of opioid administration is often preferred by patients and has been widely used in postsurgical and obstetric patients to effectively treat their pain. PCA allows for faster intervention on pain limiting time to treatment and peak pain levels and has also been shown to decrease total opioid dose. However, there is limited evidence in published literature assessing the feasibility of using PCA to treat the pain of AP or comparing its efficacy and safety profile compared to the more traditional physician directed analgesia. One retrospective study has shown that use of PCA was surprisingly associated with longer hospital stays and higher rates of outpatient opioid use when compared to routine physician-directed analgesia (PDA), however there are no prospective trials to study this comparison. Hence, in this study, the investigators will compare the effects of using PCA among patients with AP to that of conventional PDA.

Description

This protocol outlines a prospective study evaluating safety and clinical outcomes of magnetic resonance imaging (MRI) examinations performed on patients with cardiac implantable electrical devices (CIEDs) including pacemakers (PMs) and implantable cardioverter-defibrillators (ICDs). This prospective study aims to improve the evidence base regarding this common clinical scenario. Specifically, the investigators aim to address whether results of MRI in PM/ICD patients affect physician decision making related to clinical management strategy and planning treatment interventions. Further, this study will evaluate whether the results of MRI in these patients affects patient outcomes related to survival and adverse events during or after MRI scanning.

Description

The study is a randomized controlled trail with an observational arm and aims at collecting information on the prevalence of COVID 19 infection in seasoned yoga practitioners by comparing it with the prevalence of COVID-19 infection prevalence rates among age and gender matched control participants who do not practice yoga.

The study hypothesizes that yoga practice promotes protection and enhances recovery from the COVID-19 infection. To prove the hypothesis, the study investigators are collecting and comparing responses from seasoned yoga practitioners to age and gender matched controls participants (who do not practice yoga routinely) regarding their recovery from the COVID 19 infection. Based on validated questionnaires on perceived stress, anxiety, depression, well-being, mindfulness, joy disposition, and resilience in participants over the study duration, the investigators also collect information on participant's mental and emotional predispositions.

Description

The purpose of this study is to examine how acute nutritional challenges affect levels of several proteins involved in metabolism. These proteins will be measured in blood and fat tissue.

This study will have several aims.

One aim is to examine the effect of 72 hours of fasting on fibroblast growth factor-21 (FGF-21) levels. Participants will spend 3 days and nights in the Clinical Research Center at the Beth Israel Deaconess Medical Center in Boston, MA. Daily blood samples will be taken. Two fat samples will be taken prior to and at the end of the fast. A subset of participants will also have two MRIs, one prior to and one at the end of the fast. We will study healthy adults and obese adults with liver-biopsy-diagnosed non-alcoholic fatty liver disease (NAFLD). THIS STUDY ARM IS CURRENTLY NOT RECRUITING

Another aim is to examine the effect of low-calorie diet on FGF-21 levels. Subjects will follow a hypocaloric diet that will be designed to achieve 3-5% weight loss. We will enroll participants with liver-biopsy-diagnosed non-alcoholic fatty liver disease. Participants will report weekly to the Clinical Research Center at Beth Israel Deaconess Medical Center for weight measurements. Blood will be drawn before and after the weight loss. Participants will also have an MRI before and after the weight loss.

THIS ARM IS CURRENTLY NOT RECRUITING

Another aim of the study is to examine the effect of acute ingestion of glucose, fructose, and other sugars on serum FGF21 levels. Subjects in this study will be lean volunteers and individuals with metabolic syndrome.

Description

Goal of this project is to investigate whether increases in inflammation that result from common patterns of restricting sleep on week nights and catching up on sleep over the weekend are caused by disruption in the newly discovered inflammatory resolution pathways. These pathways are crucial in the active termination of the inflammatory response, and their disruption may contribute to ongoing unresolved inflammation, which has been observed not only during periods of sleep restriction, but also after recovery sleep has been obtained. If the hypothesis is true, it is possible that increasing the body's natural production of endogenous, inflammatory resolution mediators may provide a non-behavioral strategy to limit the inflammatory consequences in those undergoing periods of sleep restriction with intermittent recovery sleep.

Description

This study will examine the potential changes in the blood levels of a recently discovered metabolic regulator in response to changes in diet in healthy adults. Our hypothesis is that in healthy adults key regulatory factors involved in lipid oxidation will respond to changes in diet, particularly fasting and diet-induced ketosis.
