Filter by:In this project we aim to identify new biological markers by characterizing the response inflammation associated with the development and progression of M. abscessus lung disease in patients suffering from cystic fibrosis with the aim of increasing current knowledge available on the development and progression of lung disease.
Chronic constipation is a feature of children with cystic fibrosis (CF). This is postulated to be a result of inhibition of secretory activity of the gastrointestinal luminal cells due to ineffective chloride channel function. Typical laxatives that work as osmotic agents fail to produce adequate relief in this population. Maralixibat is a non-systemic bile acid transport inhibitor (IBATi) that acts by interrupting bile acid reabsorption in the ileum thus interrupting the normal enterohepatic circulation. This interruption results in a larger volume of bile acids reaching the colon and being excreted in stool. Bile acids are known to decrease bowel transit time, increase mucosal permeability and secretions, as well as alter gut microbiota resulting in diarrhea. The overarching hypothesis of the study is that Maralixibat will improve stool consistency in children (Age <18 years) with cystic fibrosis and constipation (Bristol Stool Scale <4). Specifically, we aim to test the hypothesis that IBATi improves the consistency of stool to Bristol scale >4 in children with CF and constipation. We will recruit a total of 20 patients with CF and constipation (defined as Bristol Stool Scale <4 for 1 week prior to enrollment while on a stable laxative regimen for at least 4 weeks.) Design is a 'Within-Subjects' study by which each enrolled patient will take Maralixibat for 2 weeks total in addition to their stable laxative regimen during the study. Stool consistency & ease of defecation will be recorded before and during the study period by families of enrolled patients via materials provided by the investigators. Stool consistency and ease of defecation will be compared before and after initiation of Maralixibat. The primary endpoint: Improvement in stool consistency to Bristol scale >4 in children with CF and constipation. The secondary endpoint: Improvement in ease of defecation in children with CF and constipation. This will be measured via survey using a standardized scale (Bristol Stool Scale) and questionnaires developed by the research team. Analysis will involve comparison of pre-intervention to post-intervention stool consistency & survey
This protocol is intended as a basket protocol designed to evaluate the use of Fibroblast Activating Protein (FAP) PET/CT in imaging the presence of fibrosis caused by a variety of medical conditions where fibrosis is believed to lead to pathological effects and poor prognosis.
The main objective of the study is to assess the potential of time-frequency representation and analysis of pulmonary sounds collected with an electronic stethoscope, as part of the routine monitoring of patients with cystic fibrosis, COPD or pulmonary fibrosis.
The purpose of this study is to work with patients diagnosed with end-stage liver disease to understand their perspectives on the Health at Home (H@H) Program, including desired outcomes and expectations, perceived barriers, and drivers. H@H is an emerging model of home-based care, designed to extend traditional, inpatient hospital care which may address these needs. Through H@H, acute medical care services as well as ancillary care such as rehabilitation therapy can be delivered in the home. The study is divided into three phases: Phase 1 occurs while the participant is an inpatient. Phase 2 is when the actual H@H program takes place as part of the participant's clinical care. The study team will not be involved in the Phase 2 - H@H program as it will be conducted by the clinical staff. Phase 3, at which point the participant enters a rehabilitation phase to transition the patient to self-management, involves a research jam session with the participant and caregiver to assess the value of the program.
This is an observational ambispective cohort study to validate the Baveno VI guideline and develop a new diagnostic model to screen high-risk varices (HRV) of liver cirrhosis using iLivTouch.
Proton pump inhibitors (PPIs) inappropriate use, in patients with cirrhosis, presents a significant clinical challenge. This study evaluates overprescription and misuse of PPIs in cirrhotic patients. The patterns of use of PPIs will be classified into two groups based on adherence to the proven indications: Group A: Inappropriate use of PPI, Group B: Appropriate use of PPI. We will estimate the prevalence of PPI misuse in cirrhotics and correlate it with different factors.
The goal of this clinical study is to evaluate the efficacy and safety of Longidaza®, lyophilizate for preparation of solution for injection, at a dose of 3000 IU compared to placebo in the treatment of adult patients with residual changes in the lungs after COVID-19 infection
OPAL is a multicenter observational study, following the natural disease trajectory of participants who have permanent damage to their liver caused by scarring, sometimes also referred to as liver cirrhosis. These participants will also have recently had an acute worsening of their liver disease, which is also known as a hepatic decompensating event, which has resulted in them being admitted to hospital or required them to seek medical attention as an outpatient.
Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease (NAFLD), a major global public health concern, is commonly associated with obesity, diabetes, and dyslipidemia. MASLD is currently the most common cause of chronic liver disease affecting about 80% of people with obesity, ranging from simple fat deposits in the liver to Metabolic Dysfunction-Associated Steatohepatitis (MASH), cellular injury, advanced fibrosis, cirrhosis, or hepatocellular carcinoma. Patients with MASH are also at risk for cardiovascular disease and mortality. There is no universally approved medication for MASH. Weight loss remains the cornerstone of MASH treatment. Patients meeting the inclusion and exclusion criteria and who give informed consent will be enrolled in the trial and undergo the baseline liver biopsy (if none available). Approximately 120 patients with MASH and liver fibrosis (F1-F4 in baseline liver biopsy) will be randomized in a 1:1 ratio to metabolic surgery or medical treatment (incretin-based therapies ± other medical therapies for MASH) and followed for 2 years at which time a repeat liver biopsy will be performed for the assessment of the primary end point.
