COVID-19 : Pulmonary Ultrasound in Primary Care

Covid19Pulmonary Infection2 more

COVID-19 infection are characterized by fever and signs of acute respiratory infection. A worsening of respiratory symptoms that can lead to respiratory failure. The decompensation can then be brutal and require rapid recourse to respiratory assistance. The contribution of clinical examination (auscultation and monitoring of oxygen saturation in particular) remains unsatisfactory in predicting an unfavorable course. The interest of pulmonary ultrasound is known in the management of pulmonary infections. However, estimating the severity of lung damage at an early stage could be of great help in monitoring and caring for patients. Ultrasound could meet this need in general practice, the chest scanner is often unavailable in these situations. Ultrasound signs are associated with severe forms. The contribution of pulmonary ultrasound seems particularly interesting in the context of the reassessment of patients during the worsening phase of symptoms (D5-D10). Estimate the prevalence of ultrasound signs in patients with an acute respiratory infection suspected or confirmed to be COVID-19, at the time of the worsening phase (between D5 and D10 of the onset of symptoms). The prevalence of ultrasound lung lesions under COVID-19 may be essential to consider the development of the ultrasound tool in primary care. Indeed, if the contribution of ultrasound is now recognized in intensive care or emergency, its place in general medicine still raises questions.

Driving Pressure And EFL in Adult Cardiac Surgery

Respiratory FailurePneumothorax4 more

During general anesthesia, functional residual capacity (FRC) is reduced. If the FRC is lower than the minimum volume required to maintain the opening of the airways, there is a derecruitment of the lung parenchyma, leading to the phenomenon of expiratory flow limitation (EFL). The Driving Pressure (DP) is the difference between the plateau pressure (Pplateau) and the Positive End-Expiratory Pressure (PEEP), and estimates the lung strain. The incidence of EFL and the importance of DP are not known in adult cardiac surgery, so it's necessary a study to assess both. The primary end-point of the study is to evaluate the correlation of DP and EFL with PPCs in adult cardiac surgery. The secondary end-point of the study is to evaluate: the mechanical ventilation time, the length of ICU and hospital stay, the rehospitalization and mortality. It will be a prospective, observational, non-pharmacological study. It will enroll 200 patients undergoing elective adult cardiac surgery.

A Study to Determine the Causes and Identify Increases in Influenza-Like Illness (ILI) in Mexico...

Influenza Nos or Influenza-like IllnessAcute Respiratory Infections

The purpose of this observational study is to characterize individuals in Mexico who seek medical care for influenza-like illness (ILI) and Severe Acute Respiratory Infection (SARI), describe seasonal pattern of the pathological agents associated with ILI and SARI and to identify changes in severity of disease caused by a specific agent.

Evaluation of Accuracy and Ease of Use of the FilmArray™ Respiratory Panel (RP EZ) in a CLIA-Waived...

Upper Respiratory Infections

The purpose of this study is to assess the accuracy and ease-of-use of a simplified FilmArray Respiratory Panel test (FilmArray RP EZ) when performed according to the manufacturer's instructions by personnel in laboratories holding Clinical Laboratory Improvement Amendments (CLIA) waivers (or equivalent) on nasopharyngeal swab samples obtained from volunteers with signs and/or symptoms of a respiratory infection. The study data will be used to support an application to the FDA for CLIA-waived categorization of FilmArray RP EZ. It is hypothesized that the results of the FilmArray RP EZ test performed in a laboratory with CLIA waiver with be 95% accurate when compared to FilmArray RP testing performed in a lab with a moderate or high complexity CLIA certification.

Oral Symptoms of COVID-19 Among Infected Medical Doctors

COVID-19 Respiratory Infection

Oral symptoms of corona virus disease have been reported by many studies. The lack of direct contact between the dentist and the patient during the active disease presented an obstacle to build a strong body of evidence. the aim of the study is to report the oral symptoms of COVID-19 and correlate the occurrence of these symptoms with various disease-related factors.

COVID-19 Infections and Mortality in Long-term Care Facilities During the First Wave

Covid19Death8 more

The medical charts of all COVID-19 cases (n=1200) from 17 long-term care facilities in Montreal, Canada will be reviewed, to compare patients who survived to patients who did not survive. Through multilevel logistic regression, the risk of death will be estimated for institutional predictors of mortality, while controlling for individual risk factors. Individual covariates include clinical features (age, sex, Charlston comorbidity index, SMAF autonomy score, severity criteria) and medical treatments (IV fluids, anticoagulation, oxygen, regular opiates, corticosteroids). Aggregate covariates include epidemiological data (attack rates, timing of outbreak) and institutional characteristics (number of beds, air exchange per hour, presence of a dedicated COVID-19 unit at the time of outbreak, staff compliance to infection control measures, staff infection rates, understaffing, proportion of semi-private rooms, proportion of wandering wards and other special units).

Gene Polymorphism of IL17 and IL 23

COVID-19 Respiratory Infection

rates are in such considerable amount among large population base. The pathogenesis of COVID-19 implicates a potent inflammatory response, involving a complex group of mediators including interleukins. These pleiotropic cytokines are secreted at the region of inflammation and released into the circulation by a variety of different cell types, including macrophages, lymphocytes, endothelial cells, epithelial cells during sepsis and acute organ injuries. There has recently found a number of studies reporting that the cytokine storms take part in the course of COVID-19

Wide Scale Monitoring for Acute Respiratory Infection Using a Mobile-Based Study Platform

Covid19Influenza3 more

This is a prospective observational study using a mobile study platform (app) that is designed for use on Android phones. Study participants will provide baseline demographic and medical information and report symptoms of respiratory infection on a weekly basis using the app. Participants will also report use of prevention techniques on the weekly survey. Mobility data will be collected passively using the sensors on the participant's smartphone, if the participant has granted the proper device permissions. The overall goals of the study are to track spread of coronavirus-like illness (CLI), influenza-like illness (ILI) and non-specific respiratory illness (NSRI) on a near-real time basis and identify specific behaviors associated with an increased or decreased risk of developing these conditions.
