Imaging Sodium and Lymphatics in Lymphedema
Lymphedema of LegLymphedema2 moreRecent evidence supports lymphatic regulation of tissue sodium handling, however fundamental gaps persist in knowledge regarding the role of lymphatics in human diseases of sodium dysregulation. The goal of this work is to apply novel, noninvasive imaging tools to measure relationships between lymphatic function and tissue sodium in patients with well-characterized lymphedema. Findings are intended to inform mechanisms of lymphatic clearance of tissue sodium, and provide novel imaging biomarkers of lymphedema progression and treatment response.
Comparison of Pulmonary Telerehabilitation and Physical Activity Recommendations in Patients With...
COVID-19Pulmonary FibrosisRehabilitation plays a very important role in the management of patients with COVID-19, focusing on respiratory and motor functions, and therefore the importance of establishing treatment strategies to ensure optimal recovery of these patients has been emphasized. It has been stated that physical activity recommendations should be clarified for the management of symptoms associated with prolonged COVID-19 Syndrome and for the continuation of activities of daily living. It has been stated that after COVID-19 pneumonia, it is necessary to evaluate the physical functions of patients with long-term follow-up and to establish rehabilitation programs. The importance of being included in the rehabilitation program was emphasized, especially for patients with lung fibrosis. The primary aim of this study was to compare the effects of pulmonary telerehabilitation and physical activity recommendations on exercise capacity and peripheral muscle strength in patients with pulmonary fibrosis due to COVID-19. The secondary aim of this study is to compare the effects of pulmonary telerehabilitation and physical activity recommendations on symptoms, activity and participation in patients with pulmonary fibrosis due to COVID-19.

Volume Resuscitation in Cirrhosis With Sepsis Induced Hypotension
CirrhosisLiver2 moreIn critically ill patients with liver disease like cirrhosis or ACLF, fluid therapy needs to be instituted after identification of patients who will be fluid responsive and initiate appropriate inotropes early to prevent the mortality associated with fluid overload. The parameters and methodology used for assessing fluid responsiveness have been studied earlier, but the optimum method is not established. Existing recommendations based on data regarding fluid responsiveness and choice of fluid for resuscitation from intensive care units in general cannot be applied to those with liver disease as the hemodynamic alterations that occur with liver disease, presence of hypoalbuminemia at baseline and presence of cardiac dysfunction interfere with the conventional methods of fluid status assessment, fluid responsiveness as well as the response to different types of resuscitation fluids. Therefore the investigators attempt to compare various methods to estimate current intravascular volume status of patient which could be helpful in guiding fluid therapy.
Monocytes as Predictors of Cystic Fibrosis-related Bone Disease
Cystic FibrosisHypothesis: Circulating monocytes RANK and MCSF-R expression is predictive of Cystic Fibrosis-related Bone Disease. Study design: Single-center comparative cross-sectional study Population: Patients with a CFTR channel mutation causing cystic fibrosis consulting the Centre de Ressources et de Compétences de la Mucoviscidose (CRCM) at Reims University Hospital will be recruited. Healthy controls will be recruited from donors at the Etablissement Français du Sang Grand Est, Reims. Judgment criteria: - Main judgment criterion: X Expression level of CD115 (MCSF receptor) and CD265 (RANK) evaluated by flow cytometry receptors on the membranes of circulating monocytes. - Secondary judgment criteria: X Rate of circulating CD115 +, CD265 +, CD115 + / CD265 + monocytes X Number of multinucleated cells with more than 2 nuclei and with an actin ring observed under fluorescence microscopy after osteoclastic differentiation X Surface of dentin resorbed in vitro by osteoclasts during an osteoclastic functionality test on dentin X Serum S1P levels assayed by ELISA technique. Investigation plan: Any eligible patient will be offered to participate in the study during the consultation at the CRCM. If the patient agrees to participate in the study, he/she will be included. Participation in the study will not affect its coverage. Participation will lead to the collection of three tubes of whole blood additional to those used as part of usual care, as well as the collection of demographic data (age, sex, height, weight, body mass index), sports practice, clinical images and interpretation, medical history (diabetes, infectious status, bone metabolism disorders, drug treatments followed, psychiatric disorders). Any subsequent donor from the EFS GE collected under the ALC / PIL / DIR / AJR / FO / 606 agreement and presenting characteristics of age +/- 2 years and identical gender will then be included. Statistical analysis plan: Qualitative variables will be described in terms of number and percentage. The quantitative distribution variables according to the Normal law will be described in the form of mean +/- standard deviation or in the form of boxplots (median, quartiles, deciles) if a distribution not following the Normal law is observed. ANOVA test, non-parametric Wilcoxon signed-rank test or chi² test will be aplied depending on the application conditions. A value of p <0.05 will be considered statistically significant.
Coagulation Parameters With Albumin in Decompensated Cirrhosis (CoPA-D).
Decompensated CirrhosisAlbumin is commonly used plasma expander in patients of decompensated cirrhosis and has been found to have many beneficial effects, with few studies showing that maintenance of serum albumin levels above 3 g/dl has improved outcomes and mortality leading to widespread utilization in patients with cirrhosis of the liver. While 20% human albumin solution has been subject to in-depth analysis along several fronts, it's effects on coagulation parameters is unknown. With cirrhosis being a state of dysregulated clotting and bleeding, it is imperative to know the effects of such a widely used plasma expander on coagulation. The aim of this study is to evaluate the effects of albumin on coagulation parameters in patients of decompensated cirrhosis.
COVID-19 Antibody Responses In Cystic Fibrosis
Covid19Cystic FibrosisCoronavirus disease 2019 (COVID-19) which is caused by the virus SARS-CoV-2 has resulted in an ongoing global pandemic. It is unclear whether the relatively low number of reported cases of COVID-19 in people with CF (pwCF) is due to enhanced infection prevention practices or whether pwCF have protective genetic/immune factors. This study aims to prospectively assess the proportion of pwCF, including both adults and children with CF who have evidence of SARS-CoV-2 antibodies over a two-year period. This study will also examine whether pwCF who have antibodies for SARS-CoV-2 have a different clinical presentation and what impact this has on their CF disease. The proposed study will recruit pwCF from paediatric and adult CF centres throughout the United Kingdom. Serological testing to detect antibodies will be performed on blood samples taken at month 0, 6, 12, 18 and 24 with additional time-points if bloodwork is available via normal clinical care. Clinical data on, lung function, CF-related medical history, pulmonary exacerbations, antibiotic use, and microbiology and vaccination receipt, will be collected during routine clinical assessments. Associations will be examined between socio-demographic and clinical variables and serologic testing. The effects of SARS-CoV-2 infection on clinical outcomes and analyse end-points will be examined to explore any age-related or gender-based differences, as well as subgroup analysis of outcomes in lung-transplant recipients and pwCF receiving CFTR modulator therapies. As pwCF receive COVID-19 vaccination a comparison of the development and progression of anti-SARS-CoV-2 antibodies in pwCF following natural infection and vaccination SARS-CoV-2 over time will be performed.

Study of microRNAs in a Decompensated Cirrhosis
CirrhosisAcute DecompensationCirrhotic patients are at higher risk of sepsis due to impaired innate and adaptive immune responses. Septic complications represent a major issue in the management of cirrhotic patients, with a 1-month mortality rate of 23%, which increases to 80% at 3 months in case of associated organ failure. Delay to treatment initiation during a septic episode may increase the risk of complications and mortality of cirrhotic patients. However, the inappropriate use of antibiotics exposes cirrhotic patients to the risk of more severe infections due to multi-resistant organisms or fungi. The use of diagnostic markers for sepsis is limited in the context of cirrhosis because of the lack of hepatic synthesis of these markers on the one hand and non-specific inflammation related to cirrhosis on the other hand. Therefore, it is necessary to develop new tools for the early diagnosis of sepsis and appropriate management of cirrhotic patients. The interest of microRNAs (miRNAs) in the diagnosis and prognosis of septic shock has been reported in the general population. No studies have described circulating miRNAs or reported their interest in the diagnosis of sepsis in a population of cirrhotic patients with acute decompensation (AD). This preliminary study of 800 circulating miRNAs will be performed in a cohort of patients with acute cirrhosis decompensation, for whom the incidence of sepsis is estimated at 40%. The aim to evaluate the interest and feasibility of a larger study on the interest of circulating miRNAs in the early diagnosis of sepsis in cirrhotic patients. The long-term objective of this study is the development of biomarkers for the early management of cirrhotic patients with sepsis and the rationalization of antibiotic use to improve their prognosis.
