Filter by:Nonalcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease in the United States. The most advanced forms of NAFLD are associated with increased liver-related mortality and lower overall survival. The current standard of care for NAFLD is lifestyle changes through diet and exercise. The human genome and regulation of gene expression is influenced by physical activity. NAFLD is a prothrombotic state with derangements in all three phases of hemostasis leading to clinically important clotting events. Exercise can improve coagulation in healthy persons. In this proposal, we seek to begin a line of work to answer the question "Can lifestyle changes effectively mitigate the increased risk of clotting in patients with NAFLD?" focusing initially on the at-risk population genetically susceptible to advanced disease.
This study evaluates the efficacy, safety and tolerability of PBK-1701TC for bowel cleansing before colonoscopy. Half the participants will receive PBK-1701TC and while the other will receive standard oral preparation.
The aim of this study is to evaluate the potential improvement in colonoscopy procedure's outcomes when using the Pure-Vu System in hospitalized patients who are indicated for colonoscopy procedure.
The primary objective of this multicenter, prospective, randomized study is to evaluate the performance of Pure-Vu System in cleansing patients' colon who are indicated for a colonoscopy procedure using one of two different reduce bowel preparation regimes.in addition, the cecum intubation rate, time to cecum, total procedure time, and adverse event will be evaluated.
This study proposes to establish a CT radiomics-based prediction model for identifying metastasis of each station lymph nodes in gastric cancer.
Emergency laparotomies, which most often is performed due to high risk disease (bowel obstruction, ischemia, perforation, etc.), make up 11 % of surgical procedures in emergency surgical departments, however, give rise to 80 % of all postoperative complications. The 30-day mortality rates in relation to these emergent procedures have been reported between 14-30 %, with even higher numbers for frail and older patients. The specific reasons for these outcomes are not yet known, however, a combination of preexisting comorbidities, acute illness, sepsis, and the surgical stress response that arise during- and after the surgical procedure due to the activation of the immunological and humoral system, is most likely to blame. The complex endocrinological response and consequences of this response to emergency surgery are sparsely reported in the literature. The aim of this PHASE project is to evaluate and describe the temporal endocrine, endothelial and immunological changes after major emergency abdominal surgery, and to associate these changes with clinical postoperative outcomes.
This is a quality improvement health services study in the Division of Gastroenterology at Beth Israel Deaconess Medical Center (BIDMC).
This study aims to investigate how knowledge of gluten immunogenic peptide (GIP) levels in stool and urine affects subsequent adherence to a gluten-free diet. Half of the participants will receive results in real-time using a home device and the other half will store samples to be tested at the end of the 30 week study. Participants will also have a diet review with a dietitian at the beginning of the end of their study and be asked questions about their symptoms, gluten-free diet adherence and quality of life.
Irritable bowel syndrome (IBS) is a disorder of gastrointestinal function characterized by abdominal symptoms and pain associated with alterations in bowel habit. The condition impacts on the quality of life of at least 10% of the population, impacts on activities of daily living and is associated with considerable direct and indirect costs to the individual, the health system and society. The etiology of IBS appears multifactorial and several mechanisms, among them mucosal inflammation, abnormal intestinal motility, visceral hypersensitivity and psychological factors, appear to be involved. An underlying pathophysiology, namely Joint Hypermobility (JH) and Joint Hypermobility Syndrome (JHS), that we are going to study, have recently gained increasing attention in patients with functional bowel disease. One factor which was shown in previous IBS-studies to reduce abdominal symptoms is a FODMAP diet. To identify FGID patients which profit most from different diagnostics and therapies (such as FODMAP diet) we are going to carry out a study analyzing different subtypes of FGID (in particular IBS, FD, functional abdominal pain/bloating) for demographics, clinical diagnostics (e.g. nutrient challenge testing, microbiome testing, anorectal manometry and MR defecography), comorbidities (in particular JH, JHS and psychological comorbidities) and treatment.
Prospective study so as to evaluate CONECCT score to determine both histological tissue and therapeutic choice
