Background and Rationale:
T cells play a critical role in antiviral immunity, their level was dramatically reduced in COVID-19 patients. There is a negative correlation between T cell numbers and cytokines serum level in COVID-19 patients. In those patients, there is up-regulation of inflammatory
COVID-19 is a rapidly evolving pandemic with approximately 5% of all patients requiring admission to the intensive care unit. In critically ill patients infected with COVID-19, ARDS is found in 40%, more than 25% require continuous renal replacement therapy, and more than 10% develop vasodilatory
The clinical status of patients was evaluated before each pulse, including blood pressure monitoring, glucose level monitoring and symptoms of infection. HR and BP was measured continuously for 3 consecutive days (the day before, the day of IVMP and the day after IVMP) during 1st, 6th and 12th IVMP
Patients hospitalized with COVID-19 predominantly die of organ failure due to a surge of pro-inflammatory cytokines triggering the need for mechanical ventilation, often due to acute respiratory distress syndrome (ARDS). Known as a cytokine storm, the surge in cytokines is similar to the excessive
Rationale
1.1. Vasoplegia and cardiac surgery:
Vasoplegia Syndrome (VS), prevailing in about 20% of cardiac surgical procedures (1), is defined as low mean arterial pressure (MAP) with normal or high cardiac indices and which is resistant to treatment with the commonly used vasopressors. (2,3)
Severe obesity, afflicting ~8% of adolescents in the U.S., is a serious and challenging medical and public health problem. The number and levels of cardiovascular risk factors are considerably higher in the context of severe obesity compared to milder forms of obesity. Approximately 85% of youth
Stages of the study
The project will be carried out in 5 phases distributed in 3 continuous periods of time.
- Stage 1 - 2 month period (observational period).
- Collection of patient information for bundle/protocol development.
- Stage 2 - 3 month period.
- Protocol / bundle development according
Hypothesis
Stellate ganglion blockade in patients with moderate and severe brain damage:
1. Increases the diameter of the brain arteries and blood flow through the brain
2. Do not interfere with intracranial pressure
3. Reduces aseptic inflammatory reaction of the damaged brains measured by IL-6 and
Design: This is a single center, cross-sectional study of patients with multiple sclerosis, who will each, undergo both, [C-11]MRB-PET (norepinephrine transporter binding) and [F-18]PBR06-PET (microglial activation), in addition to 7 Tesla brain MRIs. Patients will also undergo cross-sectional
The proposed study will examine physiologic responses to acute psychological challenge in the laboratory among healthy adults. It is widely accepted that there is an increase in circulating markers of inflammation following a single bout of laboratory stress. This increase in systemic inflammation
Background: Risk of cardiovascular diseases (CVD) is significantly elevated in patients with chronic kidney disease (CKD). Arterial dysfunction is an important nontraditional CV risk factor gaining increased recognition in the field of nephrology. While many changes likely contribute to the
The primary effects of CytoSorb therapy, are, among many others, an improvement in hemodynamics, metobolism, and capillary integrity, with effects of adsorption seeming to reach far beyond mere cytokine adsorption.
Clinically, several publications have shown that certain patient populations benefit
