Rapid Changes In Vascular Compliance Contribute To Cerebrovascular Adjustments During Vasovagal Syncope (Vvs), Aleena Sajid
Rapid Changes In Vascular Compliance Contribute To Cerebrovascular Adjustments During Vasovagal Syncope (Vvs), Aleena Sajid
Undergraduate Student Research Internships Conference
Background: The rapid reduction in arterial pressure (AP) during VVS is associated with a decline in diastolic cerebral blood velocity (CBV) and maintained systolic CBV. We tested the hypothesis that this response may represent increased cerebrovascular compliance (Ci) in the presence of rapid hypotension.
Methods: AP and CBV were recorded from 14 otherwise healthy patients (34 ± 11 years) at rest and during head-up tilt (80°, 5-28 min). Baseline, mid-tilt, and VVS were analyzed. Individual AP and CBV waveforms were input into a modified Windkessel model to calculate Ci.
Results: Upright posture resulted in a decrease in CBV (-9 ± …

Fibrosis is a progressive and typically irreversible disease process characterized by the excessive deposition of collagen in organs and in tissues of the musculoskeletal (MSK) system1,2. This process, which causes loss of organ and tissue function, can be initiated by micro-traumas3, an excessive and/or prolonged immune response1, the activation and proliferation of fibrosis-inducing progenitor cells4, and a pro-fibrotic extra-cellular microenvironment5. In parallel with the events that initiate fibrosis, genetic or environmental influences may cause cells and tissues to become predisposed to fibrosis development prior to initiation. This suggests that these …

Background: Acute respiratory distress syndrome (ARDS) is defined as severe lung dysfunction that occurs after an insult to the lung such as an infection. The lung dysfunction in ARDS is due to alterations to surfactant, a lipid-protein mixture coats the inside of the lung and …
