Healthcare-associated Links in Transmission of Nontuberculous Mycobacteria in Cystic Fibrosis
Cystic FibrosisNontuberculous Mycobacterium InfectionSources of NTM infection and modes of transmission among CF patients are poorly understood. Healthcare-associated transmission of NTM among CF patients has been suspected and is of growing concern for CF Centers. There is a need for a systematic evidence-based approach to investigating potential episodes of healthcare-associated transmission. Clusters of highly similar strains of NTM in CF patients cared for at the same CF Center may arise from healthcare sources including patient-to-patient transmission and/or acquisition from water sources within a healthcare setting. The primary objective of the study is to facilitate a standardized process by which CF Centers may perform data abstraction on patients identified with highly similar NTM isolates and determine if clustered NTM strains are related to strains isolated from healthcare setting water biofilm sources. HALT NTM is available to the entire CF Foundation Care Network, under a collaborative agreement, to initiate a standardized, independent, confidential, internal NTM outbreak investigation. Patients that are identified by whole genome sequencing as having highly similar NTM strains and receiving care in the same CF Care Center are eligible. The study's primary endpoint is to identify potential modes and sources of healthcare-associated acquisition of CF NTM, thereby revealing risk factors for NTM acquisition.

UAB HRFD Core Center: Core A: The Hepato/Renal Fibrocystic Diseases Translational Resource
Hepato/Renal Fibrocystic DiseaseAutosomal Recessive Polycystic Kidney Disease8 moreIn 2005, The University of Alabama at Birmingham established a NIDDK-funded, interdisciplinary center of excellence in PKD-related research, with specific emphasis on recessive PKD. In the previous Core Center award period, we developed a Core Resource to capture clinical and mutational data for ARPKD patients ("Core A: ARPKD Clinical and Genetic Resource", NCT00575705). However, studies in the last several years have demonstrated that ARPKD and other single gene disorders characterized by renal cystic disease and extra-renal phenotypes share numerous pathogenic features. In the current competitively- renewed Center, we have expanded this Core resource to include other hepato/renal fibrocystic diseases. Goals for the Core A: The Hepato/Renal Fibrocystic Diseases Translational Resource are: - Clinical Database: • Expand our comprehensive Clinical Database to include information from all patients who meet the inclusion criteria for hepato/renal fibrocystic diseases. - Mutational Database: Test children with ARPKD and other hepato/renal fibrocystic disease to identify genetic mutations, establish a DNA bank for patients with hepato/renal fibrocystic diseases and develop a Mutational Database. This Database will be capable of linking clinical and mutational information via a unique identifier in a searchable format to facilitate genetic research (e.g. genotype-phenotype correlations, new disease gene studies, and modifier gene studies), translational studies, and clinical trials. 3- Tissue Resource: Much of the research that is performed on diseases of the kidney, including recessive genetic diseases, requires human tissue from both affected as well as non-affected (controls) individuals. In this Core Resource, we are establishing an independent tissue resource which would supply investigators throughout North America with samples of hepato/renal fibrocystic disease affected tissues for studies of these disorders. 4- Educational Resource: Expand our multi-media, web-based resource to provide a reliable up-to-date, and comprehensive informational resource for ARPKD and Hepato/Renal Diseases families, their physicians, and genetic counselors. All the information regarding participation in "Core A: The Hepato/Renal Fibrocystic Diseases Translational Resource" is available at: http://www.arpkdstudies.uab.edu/.

Explanted Lung Tissues With Pulmonary Fibrosis
Pulmonary FibrosisThe goal of this study is to use the tissues from the explanted lungs in order to better study the cause of pulmonary fibrosis at a cellular level.

Analysis of Specimens From Individuals With Pulmonary Fibrosis
Pulmonary FibrosisHealthy Volunteers1 moreThe etiology of pulmonary fibrosis is unknown. Analyses of blood, genomic DNA, and specimens procured by bronchoscopy, lung biopsy, lung transplantation, clinically-indicated extra-pulmonary biopsies, or post-mortem examination from individuals with this disorder may contribute to our understanding of the pathogenic mechanisms of pulmonary fibrosis. The purpose of this protocol is to procure and analyze blood, genomic DNA, and specimens by bronchoscopy, lung biopsy, lung transplantation, extra-pulmonary biopsies, or post-mortem examination from subjects with pulmonary fibrosis. In addition, blood, genomic DNA, clinically-indicated extra-pulmonary biopsies, as well as bronchoscopy and post-mortem examination specimens may be procured and analyzed from relatives of subjects with hereditary forms of pulmonary fibrosis; blood, genomic DNA, and bronchoscopy specimens may be procured from healthy research volunteers....

Idiopathic Pulmonary Fibrosis and Serum Bank
Idiopathic Pulmonary FibrosisLung Diseases1 moreIdiopathic pulmonary fibrosis (IPF) is the most common form of chronic idiopathic diffuse interstitial lung disease (DILD) in adults. It is a fibroproliferative, irreversible disease of unknown cause, usually progressive, occurring mainly from the age of 60 and limited to the lungs. IPF is a serious disease with a median survival rate at diagnosis of 3 years. The aim of the study is to set up a biocollection of serum from patients in a context of idiopathic DILD and a possible or confirmed diagnosis of common interstitial lung disease by chest CT. Patients will be recruited at the consultations of the Rennes Rare Lung Disease Competence Centre. These will be patients in stable condition or in acute exacerbation of IPF.

Evaluation of Kidney Graft's Fibrosis With Real Time Shear-wave Elastography
Kidney GraftKidney graft's fibrosis is correlated with prognostic of kidney's graft, wathever the initial etiology. Actually, that evaluation is based on histologic score of Banff FI/AT (0 to III). It is obtained thanks to punction-biopsy, which is invasive and can lead complications. This exam is systematic on M3 of the transplantation. Tissue's fibrosis is a proliferation of extracellular matrix, leading to an increase of fibrosed tissue rigidity. Elastography is an ultrasound technique allowing evaluation of tissues' rigidity. The purpose is the validation of elastograhpy, innovative and non -invasive technique, and more specifically Shear Wave Elastography (SWE). For this, strain ratio (SR) could improve intra-operator variability and estimate fibrosis' degree of kidney's graft.

TIPS in Patients With Decompensated Liver Cirrhosis
Decompensated Liver CirrhosisThis is a single center patient registry of patients receiving a transjugular intrahepatic portosystemic shunt (TIPS) at Hannover Medical School. By collecting and analyzing clinical data as well as blood samples, the overall aim is to optimize TIPS therapy (e.g. specify selection criteria).

Predictive Properties of Myocardial Fibrosis Biomarkers on the Outcome of Atrial Fibrillation Ablation...
Women and Men Over 18 Years OldAF Ablation (ECS recommendation2020&ACS2014) Either for Paroxysmal AF Unresponsive to Anti-arrhythmic Treatment Either for Persisting Symptomatic AF1 moreAtrial fibrillation (AF) is the most common cardiac arrhythmia. As an independent predictor of cardiovascular mortality, particularly for stroke, its management is a real public health issue. AF is associated with diabetes, obesity, hypertension, heart failure and, occasionally, hyperthyroidism. Atrial fibrosis is one of the major players in the genesis and maintenance of AF. It has a strong impact on rhythmic prognosis and treatment success. Currently the AF ablation is the treatment recommended by the European Society of Cardiology (ESC) and by the American Society of Cardiology. The rate of AF recurrence is variable according to the patient characteristics and remains unfortunately today difficult to predict. Abnormal concentrations of circulating biomarkers reflecting the underlying pathophysiologic mechanisms of myocardial fibrosis could help to identify patients at higher risk of developing AF and/or AF recurrence after ablation. Thus, the development of simple, reliable and valid biological tests of atrial fibrosis would allow the clinicians i) to estimate the potential success of AF ablation; ii) to predict AF recurrence; iv) and to propose a AF personalized therapeutic approach. The main objective of PROFIB-AF study is to identify, among biological markers (ICTP, PICP, PIIINP, sRAGE, AGE, Galectin 3, sSt2, microRNAs) of myocardial fibrosis, those which can predict the recurrence risk after AF ablation.
