Active clinical trials for "COVID-19"

The purpose of this study is to perform a secondary analysis of pre-existing de-identified limited datasets obtained from sites participating in Tier 1 (STUDY20040154: Neurologic Manifestations of COVID 19 in Children) and Tier 2 (STUDY20040278: Neuro COVID - Outcomes). The data will be used to determine the prevalence and severity of neurological symptoms among patients requiring critical care admission for confirmed or suspected novel coronavirus (COVID-19) and to determine the predictors for limitation of care in the study population, as well as, the prognosis of neurologically injured patients admitted to the ICU during the COVID-19 crisis. This study is sponsored by the Pediatric Neurocritical Care Research Group (PNCRG) and sponsored and funded in part by the Neurocritical Care Society.

CON-VINCE (COvid-19 National survey for assessing VIral spread by Non-affected CarriErs) is a national, monocentric, and longitudinal study aiming to evaluate the spread dynamics of the COVID-19 disease within the Luxembourgish population. Participants who are clinically asymptomatic or present with only mild symptoms will be followed up longitudinally, regularly tested for SARS-CoV-2 by RT-PCR, antibody status, and subjected to an epidemiological, clinical and biological phenotyping to better understand the nature, dynamics of infectivity and spread of the virus in the population. CON-VINCE will also track the psychological and socio-economic impact of long-term containment measures on the general population.

This is a protocol-driven observational study of lung ultrasound and focused echocardiography images obtained in the Emergency Department (ED) and Intensive Care Unit (ICU) settings as a part of existing standard of care. The objectives of this study are as follows: To characterize various clinical and cardiopulmonary ultrasound findings and describe their relationship with the clinical course of patients with COVID-19 in the ED and ICU. To describe, develop, and validate a prediction tool that can accurately predict the need for invasive mechanical ventilation (IMV) and acute respiratory failure in COVID-19 patients using clinical, laboratory, and ultrasound data.

A number of clinical features suggest the possibility of dysautonomia in patients infected with SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2). At the same time, there is now strong experimental evidence that SARS-CoV-2 can cross the blood-brain barrier, probably via the olfactory nerves, and reach the brain stem, which is located in close proximity. Damage to the brainstem nuclei could explain the suspected dysautonomic episodes, but also the severity of respiratory distress in infected patients, and the difficulty of ventilatory withdrawal encountered in resuscitation, potentially through damage to the ventilation control and regulation centers located in the brainstem. The objective of this study is to record the long term variability in heart rate, reflecting autonomic balance, of patients screened positive for SARS-CoV-2 throughout their stay in conventional care units at the Saint-Etienne University Hospital, in order to see whether there is an autonomic imbalance at screening, whether the worsening of the autonomic imbalance precedes the worsening of the clinical condition, and how quickly the expected correction of the autonomic imbalance follows or precedes that of the disease.

In severe COVID-19 pulmonary failure, the profound hypoxemia is mainly related to pulmonary vasodilation with altered hypoxic pulmonary vasoconstriction (HPV). Besides prone positioning, other non-ventilatory strategies may reduce the intrapulmonary shunt. This study has investigated almitrine, a pharmacological option used in standard care to improve oxygenation. A case control series of mechanically ventilated confirmed COVID-19 patients was recorded. At stable ventilatory settings, consecutive patients received two doses of almitrine (4 and 12 mcg/kg/min) at 30-45 min interval each, and were compared to 7 "control" COVID-matched patients conventionally treated. The end-point was the reduction of intra-pulmonary shunt, with an increase in partial pressure of arterial oxygen (PaO2) and central venous oxygen saturation (ScvO2).

This study will study the potential utility of the Quantra QPlus System in patients inflicted with COVID-19 disease.

In a case-series analysis, up to 20 patients undergoing elective or urgent/emergent surgery that are COVID-19 positive will be approached for patient consent. OR PathTrac (RDB Bioinformatics, Omaha, NE 68154) collection kits will be utilized for sampling of 48 sampled time/locations per patient. Patient sampling locations will include the nasopharynx and oropharynx. Operating room environmental locations will include areas in the patient care arena such as the anesthesia machine. Samples of each location will be obtained before and after treatment with UV-C (Helios, Surfacide), germicidal, ultraviolet light and other infection control practices that are currently in place, such as utilization of preoperative chlorhexidine wipes, nasal iodine, improved hand hygiene, and improved vascular care. UV-C light for environmental cleaning is not regulated by the FDA. Samples will be processed by RT-PCR for presence of SARS-CoV-2 nucleic acid. Positive samples will be sent to Dr. Stanley Perlman's lab to assess viability. Samples will also be assessed for S. aureus as a process control. We will characterize the epidemiology of perioperative SARS-CoV-2 spread as a quality improvement initiative to improve our current perioperative infection control bundle and to serve as the platform for national dissemination of a perioperative COVID-19 defense strategy.

I. Study Design: This is a single-arm feasibility study to assess the safety and efficacy of anti-SARS-CoV-2 convalescent plasma (CP) in intubated, mechanically ventilated patients with confirmed COVID-19 pneumonia by chest X-ray or chest CT. hospitalized patients with acute respiratory symptoms between 3 and 7 days after the onset of symptoms, with COVID-19. II. Study Population: Population 1: Mechanically ventilated intubated COVID-19 patients aged 18 years or older. Population 2: Hospitalized COVID-19 patients aged ≥18 years of age with respiratory symptoms within 3 to 7 days from the beginning of illness. III. Study Agent: SARS-CoV-2 convalescent plasma (1-2 units; ~200-400 mL at neutralization antibody titer >1:160.

The objective of this study is to assess three configurations of two convolutional deep neural network architectures for the classification of COVID-19 PCX images.

Cross-sectional study based on a French national survey aimed to described and identify the most frequent symptoms of COVID-19 older patients.
