Filter by:It has been found that there is an association between prevalence of odontogenic infection and systemic diseases.Cirrhosis has also been associated with poor oral health status.Treating those patients accordingly can help in reducing the source of infection to some extent and may be associated with reduction in mortality.
In this study, MRI of the lungs of healthy volunteers and participants with cystic fibrosis (stable and participants initiating CFTR modulator treatment) will be performed over a period of 6 months to determine if lung MRI is able detect structural and functional abnormalities/changes in early cystic fibrosis disease. During the 6 month period, 3 study visits will occur. 70 subjects aged 6 and older will participate in this study. Xenon MRI is a non-invasive imaging technique that does not involve x-rays or ionizing radiation. Rather, this imaging method utilizes the same hardware and software principles that are used for conventional proton MRI of patients in a hospital.
This pilot study will evaluate conventional and investigational MR imaging and spectroscopic sequences and collect data to help plan more definitive future studies.
This is an open-label, randomized study comparing a monitored ketogenic diet intervention using standard ketogenic diet (SKD) and standard of care (SOC) dietary recommendations for 16 weeks. Subjects enrolled in the standard of care group will receive a voucher to Weight Watchers after study completion.
Cystic fibrosis related diabetes (CFRD) is a major factor of morbidity and mortality at all disease stages. Insulin deficiency has serious clinical consequences by increasing malnutrition, since protein and lipid catabolism is accelerated in chronic infections. Traditionally, insulin is injected before a meal. Yet, in these patients with highly varied and often staggered nutritional intakes, insulin injection can result in an increased risk of postprandial hypoglycaemia, all the more so as CF patients exhibit decreased glucagon secretion. Recent progress in the development of new insulins mimicking the physiological secretion more closely has led to ultra-fast insulins (fast aspart), allowing for postprandial hyperglycaemia to be better controlled. In Type 1 diabetics treated with basal-bolus, faster-acting aspart insulin injected after a meal enabled metabolic control comparable to injection of aspart insulin prior to the meal. Fast apart insulin is of particular interest with regard to CFRD, wherein postprandial hyperglycaemia occurs early. In CFRD, these insulins are likewise advantageous in that they can be injected after the meal, thus permitting more flexibility in patients with highly varied diets. Moreover, the insulin dose can be adapted depending on dietary intake, thus preventing hypoglycaemia secondary to highly-varied carbohydrate intakes. Due to its flexibility, this insulin therapy is likely to be better accepted by patients with cystic fibrosis.
The main aim of the study is to set up an observational cohort with NAFLD (Non-alcoholic fatty liver disease) at different stage of disease (from simple steatosis to cirrhosis and/or HCC-Hepatocellular carcinoma) and for comparative purpose a cohort of subjects with diabetes and/or obesity and/or other risk factors (i.e. psoriasis, IBD (inflammatory bowel disease), dyslipidemia) without NAFLD in order to have a clinical phenotypical characterization and the collection of biological specimens. We will collect clinical data, biological samples and imaging results in order to perform future cross-sectional studies and/or longitudinal studies for elucidating pathways of the disease and develop and validate biomarkers for diagnosis, prognosis and monitoring liver disease and comorbidities in order to contribute to precision medicine in this field.
This is a prospective, multicenter cohort study, which subjects were obese patients requiring bariatric surgery. This study aims to explore the the effectiveness of bariatric surgery for NAFLD/NASH with fribrosis, to explore the differences in the effectiveness among sleeve gastrostomy [SG], Roux-en-Y gastric bypass [RYGB], or one anastomosis gastric bypass [OAGB], and to explore the independent effectiveness of bariatric surgery in histological remission of NAFLD/NASH. The first stage of the cohort was started in 2020, named Base-NAFLD; In May 2024, based on Base-NAFLD, we plan to continue established a secondary cohort, named Base-NASH.
The purpose of the study is to see if imaging with fluorine-18 Fluorodeoxyglucose ([18F] FDG) and fluorine-18 Displacement Per Atom ([18F]DPA-714) using positron emission tomography and computed tomography (PET/CT) will show lung inflammation and fibrosis in patients diagnosed with idiopathic pulmonary fibrosis (IPF). This study may help physicians and researchers better understand how best to treat patients with IPF in the future.
The study aims to evaluate the effect of allogeneic mesenchymal stem cell therapy on patients who suffered from liver cirrhosis caused by Hepatitis B.
Pulmonary exacerbations (PEx) are key events that lead to a decline in health status among CF patients, with many never recovering to baseline health. With the advancement of new CFTR modulators and other therapies increasing the lifespan of those living with CF, it will become increasingly important to have better strategies to manage PEx in order to have better outcomes following treatment. PEx treatment decisions will need to take into consideration the increasing frequency of antimicrobial resistance bacteria and the need to treat multiple types of bacteria at once. The purpose of this study is to analyze sputum samples from CF subjects at the time of PEx in order to identify markers of antimicrobial resistant bacteria and see how those relate to treatment responses. CF patients will be recruited from patients followed by the Adult CF Program at National Jewish Health. Within 48 hours of admission to the hospital for treatment of a PEx, subjects will be enrolled and sputum will be collected. The sputum will be processed and analyzed for the presence of antimicrobial resistant bacteria. These results will be compared to clinical data, such as spirometry and frequency of hospitalizations.
