How to construct a novel, non-invasive, accurate, and convenient method to achieve prediction of hepatic venous pressure gradient (HVPG) is an important general problem in the management of portal hypertension in cirrhosis. We plan to investigate the ability of AI analysis of Ultrasound, computed tomography (CT) or magnetic resonance (MR) to establish a risk stratification system and perform tailored management for portal hypertension in cirrhosis.
Split-thickness skin graft (STSG) is one of the most common procedures performed in plastic surgery and dermatology. The donor site of skin grafting is expected to heal without scarring. However, hypertrophic scar formation is prevalent among STSG donor sites during scar maturation and has become a significant problem at present. Hypertrophic scar results in aesthetic, physical, functional, and psychological problems, leading to a dramatic impact on patients' quality of life ultimately. There are many current therapeutic approaches for preventing and treating hypertrophic scars; however, they remain clinically unsatisfactory because many treatments have been associated with high recurrent rates, high cost, and side effects. Currently, there are no gold standards for hypertrophic scar therapy. There are many attempts to develop new treatment options for the prevention and management of scarring that are acceptable to both physicians and patients. It has previously been shown that both edible bird's nest (EBN) extract and sericin have effectiveness in reducing scar development. They might be a suitable alternative option for scar prevention and could be used safely. Therefore, the sericin hydrogel sheet impregnated with EBN extract is developed as it is believed that the synergism of these combined compounds would be a great help to prevent the development of scars. This study aims to evaluate the efficacy and safety of sericin hydrogel sheet impregnated with EBN extract for the prevention of scar formation in patients with STSG donor sites.
This study is a prospective, multi-center and observational clinical study. Investigators would like to explore the optimal emergency endoscopy timing in cirrhosis patients with esophagogastric variceal bleeding (EGVB) by evaluating and comparing the efficacy and safety of emergency endoscopy performed at different times ( within 6 hours or between 6 and 24 hours after gastroenterologic consultation ) and its impact on the short-term prognosis.
The main objective of this cohort study is to determine genetic, clinical biologic and metabolic factors associated with patient heterogeneity in regards to severity of NAFLD at diagnosis as well as during the clinical course. - at diagnosis, with the aim to better characterize patients of different severity and improve our understanding of clinical and histological heterogeneity at diagnosis - during the clinical course to better understand and predict disease progression in terms notably of fibrosis progression and progression to cirrhosis
Diabetes affects half of cystic fibrosis patients aged 30 years and older. It develops asymptomatically for a long time. Also, two options are possible: start insulin treatment now with the additional constraints associated with cystic fibrosis or wait while monitoring the patient's clinical status and initiate insulin treatment when he has developed symptoms and therefore later. In practice, the choice between these two options takes place over two medical consultations without a formalized shared decision-making process between the doctor and the patient. Shared decision-making is a decision-making process in which the healthcare provider and the patient learn about patients care options and then deliberate to reach a common agreement on the decision taken. Shared decision-making seemed particularly relevant to us in cystic fibrosis where there are complex treatment options with variable short-, medium- and long-term side effects and where the disease and its treatments have a high impact on the patient's quality of life.
1. Objective The purpose of this study is to evaluate whether there is a significant difference of early rebleeding rate (within the first 5 days after esophageal variceal ligation), late rebleeding rate (more than 5 days until 28 days after esophageal variceal ligation), and convenience level between cirrhotic patients in early diet group versus late diet group. 2. Method This study is a single blind randomised clinical trial. Subjects will be selected based on inclusion and exclusion criteria, then the subjects will be randomly divided into 2 groups, the early diet group (clear fluid diet is initiated 1 hour after esophageal variceal ligation) and the late diet group (clear fluid diet is initiated 6 hours after esophageal variceal ligation). The intervention arm is the early diet group, while the control arm is the late diet group. The primary outcome is the early rebleeding rate. The secondary outcomes are late rebleeding rate and patient's convenience level which will be measured using Visual Analogue Scale (VAS). 3. Expected result The expected result is there will be no difference in early bleeding rate, late bleeding rate, and convenience level between early diet group versus late diet group.
Exercise helps people with CF lead long, fulfilling lives. Regular exercise reduces depression and fatigue, and may play a role in preventing exacerbation. However, little is known about exercise habits in adults with CF, or the barriers to exercise that they face. During the COVID-19 pandemic, lockdowns and social distancing saw gym memberships plummet; while sale of personal exercise technology, smart-watches, and interactive home equipment exploded. As this technology becomes more cost-effective and accessible, can it be leveraged to improve CF care? This study will examine barriers to exercise in CF and the role of smart devices in exercise. Adults with CF will participate in the Exercise Behaviors/Barriers Survey, followed by a qualitative discussion on attitudes toward exercise technology, and how CF impacts exercise. We anticipate that many perceived barriers will be universal (e.g. time), while others will be unique to CF. Participants will be fitted with wrist actigraphy (FitBit Inspire 2) to measure baseline exercise. They will receive access to three smartphone apps designed for home exercise, as well as an exercise website designed for the CF community (www.activate65.org), and receive weekly phone calls from the CF care team offering motivational interviewing. Actigraphy, heart and respiratory rate, and app usage will be analyzed. After four weeks, participants will no longer receive calls. Actigraphy will be monitored four additional weeks to determine if exercise is sustained. We anticipate that exercise will increase during the intervention period, and that some activity will be sustained in the follow up period. The findings of this study will pave the way for a larger trial using this "Team and Technology" approach to investigate clinical outcomes. This study highlights the critical and timely need to investigate the barriers to exercise in CF, and effective solutions to develop sustainable exercise habits using widely-available technology from home.
Thrombocytopenia is a frequent issue in patients with cirrhosis undergoing various types of procedures (e.g. liver biopsy, endoscopy and minor surgical interventions). Thrombocytopenia < 50*10^9/L increases the risk of perioperative and postoperative bleedning and might prevent patients with cirrhosis to undergo important procedures. Doptelet is a small molecular trombopoetin agonist, which results in proliferation and differentiation of megakaryocytes in the bone marrow resulting in increased levels of thrombocytes. It is given orally as a pill and is used to increase platelet count in patients with severe thrombocytopenia (< 50*10^9/L) and cirrhosis and thus not to normalize platelet count. This study investigates the safety and efficacy of Doptelet in patients with cirrhosis and thrombocytopenia (< 50*10^9/L) undergoing minor procedures like Transjugular Adjusted Liver Biopsy (TJALB) and gastroscopy.
Respiratory diseases (asthma, cystic fibrosis, COPD…) need for the diagnosis and the follow-up the use of pulmonary function tests. These technics which are used since the nineteenth century and their discovery by Hutchinson, are now currently performed in pediatrics hospitals but they require trained personnel. Spirometry can be a difficult technic, especially for children. The accuracy and repeatability depend on many factors: equipment, patient effort, supervision and encouragement of a technician. A longitudinal follow up of measures can be good especially in pediatric populations, where children have generally more difficulties recognising their symptoms. Cystic fibrosis is a severe genetic chronic disease, that affects 1/4500 birth in France. It's a multi system disease that affects the respiratory system, with a decline in lung function over the time and consecutive to pulmonary exacerbations, the digestive system (malabsorption of fat and vitamins) and the endocrine system (diabetes). Pulmonary function is an important clinical indicator of the health of individuals with cystic fibrosis. Close monitoring of patient health with daily recording of physical measurements and symptoms didn't have a negative impact, home spirometry function test could help detect earlier a decline of the lung function and pulmonary exacerbations. Frequent exacerbations are associated with morbidity, mortality, accelerated decline in lung function and a decreased quality of life. They are also a major driver of health costs.Their early detection is a goal. Children with cystic fibrosis have more difficulties recognizing symptoms of exacerbations. Few studies in pediatric showed a good observance in realizing home spirometry, especially in young patients and those living far from the hospital and with a good satisfaction. Daily monitoring of lung function is probably too tedious for children who already have lots of medication. Medical adhesion of adolescent's patients is often suboptimal, compared with younger patients. But it's during this period that the decline of the respiratory function is the most important, with its principal cause: pulmonary exacerbations. Frequent home pulmonary function test is possible and can improve medication adherence without adding too much time, but there was no change in the decline of the FEV1 and the number of pulmonary exacerbations. The association of home monitoring of lung function and a symptom questionary (cough, sputum and dyspnea) can predict exacerbation with a good specificity and sensibility. The Mir Spirobank Smart is a bluetooth connected device, permitting patients to realize spirometry at home with a smartphone. The accuracy of the Spirobank Smart compared with a spirometry in a hospital showed a good correlation (asthma and COPD population), if it's used by trained personnel. The aim of this study is to determine the feasibility of a home respiratory monitoring in a pediatric cohort of patients with cystic fibrosis and the satisfaction of the kids, the parents and the team of the CRCM.
