The purpose of the study is to evaluate a new radiotracer called 64Cu-FBP8 for PET-MR imaging of thrombosis. The tracer has the potential of detecting thrombosis anywhere in the body, for instance in the left atrial appendage of patients with atrial fibrillation, and thereby may provide a non-invasive alternative to the current standard-of-care methods.

The bedside use of ultrasound after central venous catheter (CVCs) insertion has lagged behind other applications in medicine, thus presenting an opportunity for innovative, evidence-based research that will influence clinician behavior. This research focuses on bedside ultrasound applications as an example, to evaluate clinical practice change. Chest radiographs are associated with delays in initiating time-critical interventions and present an unexamined opportunity for improving patient care by evaluating the use of ultrasound in lieu of chest radiographs after CVC insertion. Strategic interventions for implementation are needed to hasten the adoption of this clinical innovation (ultrasound guided CVC confirmation protocol) allowing them to de-implement chest xrays when no longer indicated.

The first objective of the study is to evaluate whether a novel bio-signature (derived from a wide range of pro- and anti-nociceptive IL-1 family cytokine activity) will predict pain experienced and also release of underlying endogenous opioid neurotransmitters during an experimental nociceptive pain challenge, which will be performed while simultaneously quantifying mu-opioid receptor activity in the brain via \[11C\]-carfentanil PET neuroimaging in healthy subjects. Another objective is to evaluate whether an anti-inflammatory drug that reduces activation of IL-1b (minocycline) will perturb the balance between pro- and anti-nociceptive IL-1 cytokines and effect a reduction in pain experienced (and endogenous opioids released) during the experimental, nociceptive pain challenge. A final objective is to evaluate performance characteristics (sensitivity, accuracy, dynamic range) of the biosignature for the purpose of predicting post-operative pain. Read Less

This study aims to predict and minimize post-discharge adverse events (AEs) during care transitions through early identification and escalation of patient-reported symptoms to inpatient and ambulatory clinicians by way of predictive algorithms and clinically integrated digital health apps. We will (1) develop and prospectively validate a predictive model of post-discharge AEs for patients with multiple chronic conditions (MCC); (2) combine, adapt, extend, and iteratively refine our EHR-integrated digital health infrastructure in a series of design sessions with patient and clinician participants; (3) conduct a RCT to evaluate the impact of ePRO monitoring on post-discharge AEs for MCC patients discharged from the general medicine service across Brigham Health; and (4) use mixed methods to evaluate barriers and facilitators of implementation and use as we develop a plan for sustainability, scale, and dissemination.

The primary aim of our pilot study is to determine whether fibrosis in the heart can be measured with \[68Ga\]CBP8, a positron emission tomography (PET) probe, using PET/magnetic resonance imaging (MRI) imaging, in 30 individuals with documented cardiac amyloidosis. The investigators will also enroll 15 individuals with recent myocardial infarction and 15 individuals with hypertrophic cardiomyopathy as positive controls for fibrosis, and the investigators will enroll 5 individuals without cardiovascular disease to undergo \[68Ga\]CBP8 PET/MRI imaging as a healthy control group. The primary hypothesis of this study is that \[68Ga\]CBP8 will bind to interstitial collagen and quantify myocardial fibrosis in patients with cardiac amyloidosis. The investigators hypothesize that \[68Ga\]CBP8 uptake will be greater in patients with cardiac amyloidosis, myocardial fibrosis, and hypertrophic cardiomyopathy than in healthy controls. Secondly, the investigators also hypothesize that \[68Ga\]CBP8 activity more strongly correlates with standard MRI measures in patients with recent myocardial infarction and hypertrophic cardiomyopathy (where extracellular expansion is caused by myocardial fibrosis/collagen deposition) than in patients with cardiac amyloidosis (where myocardial fibrosis is combined with infiltration).

Hysteroscopic surgery is widely used for the treatment of gynecological diseases, such as septum, synechiae, polyp and intrauterine fibroids. The complication rate is estimated as 0.22% and includes uterine perforation, massive bleeding, and fluid overload. Operative hysteroscopy intravascular absorption (OHIA) syndrome refers to fluid overload complications from operative hysteroscopies and is considered a major complication. Report describing the clinical association between irrigation fluid temperature to intravasation rate itself or the risk of fluid overload are limited mainly to theoretical models. Due to the aforementioned, we aim to evaluated the role of temperature on absorption of the irrigation solution in hysteroscopic surgery. Read Less

Several methods for closure of trocar wounds are known in laparoscopic surgery including mostly transcutaneous or subcuticular suture or adhesive paper tape. Studies comparing laparoscopic incision closure in bariatric population are limited .This is a prospective study that will be conducted in a single tertiary medical center. s obese population comprise most of our surgical candidates, and due to the aforementioned, the aim of our study is to compare the outcomes of both techniques in obese women.

The goal of this clinical trial is to learn about time restricted eating as a weight loss intervention in adults with obesity. The main questions it aims to answer are: 1. How does the timing of the eating window (early vs late time restricted eating) affect weight loss and changes in metabolic risk factors? 2. How does time restricted eating compare to standard of care (daily caloric restriction) for weight loss and changes in metabolic risk factors? Participants will be randomly assigned to either early time restricted eating, late time restricted eating, or daily caloric restriction. 1. They will be asked to follow the assigned dietary strategy for 1 year and will receive a group-based program for instruction and support. 2. They will be asked at several times during the year to have their weight and body composition measured, provide blood samples, track their food, and wear monitors for physical activity and sleep.

This is a randomized controlled trial to assess the effect of routine exercise counseling compared to the recommendation for postprandial ambulation on infant birthweight among pregnant people with gestational diabetes mellitus. The primary outcome is birthweight percentile for gestational age at delivery. Secondary outcomes include feasibility and acceptability, need for metformin or insulin for glycemic control, mode of delivery, neonatal hypoglycemia. Participants will be counseled to either complete 20 minutes of walking after meals, or be counseled with routine exercise counseling of 30 minutes of low-impact 5x a week. Their activity will be tracked by "FitBit" pedometers and uploaded via bluetooth to a database for review. They will continue to receive routine obstetric and diabetes care. Read Less

This study meets the NIH definition of a clinical trial, but is not a treatment study. Instead, the goal of this study is to investigate how hearing ourselves speak affects the planning and execution of speech movements. The study investigates this topic in both typical speakers and in patients with Deep Brain Stimulation (DBS) implants. The main questions it aims to answer are: * Does the way we hear our own speech while talking affect future speech movements? * Can the speech of DBS patients reveal which brain areas are involved in adjusting speech movements? Participants will read words, sentences, or series of random syllables from a computer monitor while their speech is being recorded. For some participants, an electrode cap is also used to record brain activity during these tasks. And for DBS patients, the tasks will be performed with the stimulator ON and with the stimulator OFF.

The purpose of this study is to develop a database containing clinical and laboratory information for patients with Leigh syndrome. The goal is to provide a greater understanding of Leigh syndrome allowing further characterization of this disease. Read Less

The objective of this study is to improve medication, symptom, and disease management of patients with hematological malignancies and multiple chronic conditions (2 or more conditions in addition to cancer) through care coordination between pharmacists working in oncology practices and those working in primary care or community practices (Pharmacists Coordinated care Oncology Model \[PCOM\]). This is a pilot study in which the investigators will examine the association between outcome measures, but the study design and sample size are insufficient to quantify the impact of OAA initiation or OAA adherence on adherence to chronic medications. This pilot study and data analyses are being done in preparation for a larger, controlled study. Read Less
