Risk of Recurrence of Cervical Artery Dissection During Pregnancy and Puerperium
Cervical artery dissection (CAD) accounts for about 2% of all strokes, and is a major cause of stroke in young people (about 15%). Many cases of CAD during pregnancy and puerperium have been described, suggesting that pregnancy and puerperium may be potential risk factors for CAD. The purpose of this …
Lung Microbiota Analysis in Critically Ill Patients Admitted to the Intensive Care Unit.
Our study aims to evaluate the relationship between the heterogeneity of pulmonary microbiota and clinical and outcome variables among critically ill patients admitted to the intensive care unit (ICU). In patients undergoing invasive mechanical ventilation, an aliquot of bronchoalveolar lavage (BAL) fluid will be used in the microbiology laboratory for …
Retrospective Chart Review Study of Patients With PIK3CA-Related Overgrowth Spectrum Who Have Received Alpelisib
The study is a site-based retrospective non-interventional medical chart review of pediatric and adult male and female patients with PIK3CA-Related Overgrowth Spectrum (PROS). Patient-level data are abstracted from medical charts of all eligible patients at all participating sites. Information from patients treated with alpelisib will be used to describe the …
Non-specific Back Pain and Spinal Manipulation
The main purpose of this study is to identify short-term predictors of positive responses to a spinal manipulation treatment. To do this, positive responses to treatment, characterized by improvement in pain score, functional capacity, as well as the global perceived change will be evaluated using single and multiple logistic regressions …
Soluble ST2 and Cardiovascular Outcome
Cardiac surgery induces hemodynamic stress on the myocardium, and this process can be associated with significant cardiovascular morbidity and mortality. Soluble suppression of tumorigenicity 2 (sST2) is biomarker of myocardial remodeling and fibrosis; however, little is known regarding their potential association with cardiovascular events. This study aimed to investigate the …
COVID-19 Associated Lymphopenia Pathogenesis Study in Blood (CALYPSO)
Background COVID-19 is an acute respiratory syndrome. One symptom of COVID-19 is a reduction in the number of cells called lymphocytes in the blood. Lymphocytes are a type of white blood cell that fights infections. With fewer lymphocytes, the body cannot effectively fight back against SARS CoV-2, the virus that …
Antigen Presentation and Lymphocyte Response in Parkinson's Disease
The way the immune system responds to certain PD-related proteins in PD donors compared to the way it responds in persons without or fewer PD related proteins is not well studied and this study aims to analyze the autoimmune response in each group. The study involves a one time visit …
Molecular Characteristics of Gastroesophageal Adenocarcinoma (MOCHA): A Prospective Feasibility Study
Researchers are looking to further our knowledge on disease biology and treatment selection for gastroesophageal adenocarcinoma. The purpose of this study is to see how useful it is to look for changes and characteristics in your genes (molecules that contain instructions for the development and functioning of the cells) and …
Vocal Feature Analysis Algorithm
This is an observational, prospective, non-randomized, non-significant risk study collecting voice recordings from subjects who are being tested for COVID-19 by laboratory analysis of specimens obtained by nasal or naso-pharyngeal (NP) swab. Patients record their voices through an app on their mobile phone. Patients and health care providers will be …
An Observational Cohort Trial of Outcomes and Antibody Responses Following Treatment With COVID19 Convalescent Plasma in Hospitalized COVID-19 Patients
This is an observational study designed to learn more about how COVID19 convalescent plasma works in patients with COVID19 compared to those patients who did not receive convalescent plasma treatment. Information about patient recovery will be collected from participants' electronic medical records to evaluate safety, clinical outcomes, and SARS-CoV2 antibody …
