Microvascular Plug (MVP) for the Treatment of Pulmonary ArterioVenous Malformations (PAVMs)
The purpose of this study is to compare the use of the Micro Vascular Plug (MVP) system and other embolic devices in treatment of PAVMs. Pulmonary Arteriovenous Malformations (PAVMs) are abnormal connections between the pulmonary vein and the pulmonary artery. This affects blood flow between the heart and lungs which …

Maternal Perception of Fetal Movements Evaluation Using and Analyzing the Variables of Antepartum Computerized Cardiotocography: An Exploratory Study.
Several studies analysed the association of fetal movement counting with perinatal mortality and fetal outcomes. However, no one examined the relationship of the maternal perception of fetal movement with the fetal wellbeing quantifies through computerised cardiotocography. Our study evaluates the correlation between the maternal perception of fetal movement and antepartum …

Data will be collected from medical charts including, but not limited to: physical examinations, imaging studies, review of systems, age of diagnosis, quality of life surveys, growth delay assessment, metabolic control, dietary analysis, urine and blood labs, …
Non Inferiority Trial for Detection of nCOVID-19 Through Analysis of Exhaled Breath Aerosols
This study aims to evaluate several of Owlstone Medical's Breath Biopsy aerosol respiratory droplet capture techniques for the detection of nCOVID-19. These are single use disposable breath capture devices with removable filters and fitted PVA strip that directly sample exhaled breath aerosols and therefore, directly sample the primary transmission route …
Pilot Study to Evaluate Photoacoustic Imaging for Characterizing Breast Masses and Breast Tumor Response to Neoadjuvant Chemotherapy Pilot Study to Evaluate Photoacoustic Imaging for Characterizing Breast Masses and Breast Tumor Response to Neoadjuvant Chemotherapy
Our objective in this pilot study will be to identify PA parameters that can distinguish benign vs. malignant lesions, and also, if PA parameters change with within breast tumors during chemotherapy treatment over time.
COVID-19: Respiratory and Sleep Follow-up
The current project is a prospective, multicentric cohort study aiming at a multidisciplinary assessment (pulmonary, cardiometabolic, sleep and mental health) of the consequences of infection by SARS-CoV-2, 3 months after the diagnosis in order to better characterize these complications. 400 patients with a positive diagnosis of SARS-CoV-2 will be included …

Correlation Between Specific Gene Mutationand Local Immune Microenvironment and Immunotherapy Efficacy in NSCLC
Immunotherapy for PD-L1 positive patients is still ineffective in some patientswhich may be related to the complex immune microenvironment.In view of this bottleneck, further refinement of immunotyping and in-depth study of drug resistance mechanism are the most important tasks. In this observational study, we evaluated the difference of gene mutation …
