Filter by:The COVID-19 pandemic is a novel medical challenge, particularly because of the systemic nature of this disease. Indeed, COVID-19 affects several organs and systems at once. The brain is affected in several ways: direct infection of nerve cells by SARS-CoV-2, inflammation of the central nervous system, severe systemic inflammation damaging nerve cells, global cerebral ischaemia related to respiratory failure, thromboembolic events related to increased intravascular coagulation and severe psychological stress. As a result, COVID-19 sometimes manifests as neurological and neuropsychiatric symptoms such as dizziness, sleep disturbances, cognitive deficits, delirium, or severe depression. Sudden loss of smell is a common symptom associated with COVID-19 and SARS-CoV-2 infection of neurons in the olfactory system has been reported in both hamsters and humans. The vast majority of COVID-19 patients recover their olfactory function within a few weeks. However, a significant minority of infected individuals (1 in 5 cases) still suffers from olfactory disorders (anosmia, hyposmia and/or parosmia) several months after the primary infection. These olfactory disorders are frequently associated with depressive behaviour and cognitive complaints. In PET scans, it is even possible to correlate this cognitive dysfunction with hypometabolism of certain brain regions, including the olfactory gyrus. This project proposes, during one year, to evaluate and follow the evolution of the olfactory capacities of patients suffering from persistent smell disorder since one year (+/- 4 months) following COVID-19. The issue is to study the link between viral persistence in the olfactory sensory organ, chronic inflammation, and central damage to the olfactory system. The follow-up of the evolution of olfactory and neurocognitive capacities, in an integrative way by means of molecular, physiological and behavioural approaches, will inform us on the specificities of "COVID-long" and on the level of peripheral and/or central damage of the olfactory system.
This is a prospective, observational cohort registry that aims to collect data on pulmonary structure and function in healthy people and those with respiratory disease, using structural and functional pulmonary 1H-MRI and hyperpolarized 129Xe-MRI. Outcome measures generated from MRI may include but are not limited to measures of regional ventilation, pulmonary microarchitecture, and regional gas exchange. Additionally, one of the goals of the registry is to facilitate the development of novel image analysis techniques that have not yet been invented. These data will be stored along with demographic data, clinical data, and pulmonary function testing (PFT) data. This is an open registry. Eligible local and international investigators/institutions can apply for access.
In this prospective study we extracted acoustic parameters using PRAAT from patient's attempt to phonate during the clinical evaluation using a digital smart device. From these parameters we attempted (1) to define which of the PRAAT acoustic features best help to discriminate patients with dysphagia (2) to develop algorithms using sophisticated ML techniques that best classify those i) with dysphagia and those ii ) at high risk of respiratory complications due to poor cough force.
The protocol, in accordance with the objectives of ORCHESTRA project - Work Package 2, aims at investigating the characteristics and determinants of COVID-19 long-term sequelae. This goal will be reached through the harmonization of follow-up strategies across the participating cohorts to allow a standardized collection of data on COVID-19 long-term sequelae. The result will be a platform including a set of data and biomaterials from large scale international cohorts, that will be uniformly recorded, prospectively tracked and analysed. The ultimate goal will be that of providing evidence to contribute to the optimization and improvement of the management and prevention of COVID-19 sequelae. The follow-up will be organized in multiple levels of tests, according to the capability of each cohort, and will include questionnaires to collect demographic, epidemiological and clinical data, physical examination, radiological exams and biological sampling. The long-term follow-up will also allow the assessment of long-term immunological response to SARS-CoV-2 infection and its association to the vaccination and to different treatment strategies, including monoclonal antibodies.
This observational study aim to characterise patients admitted to hospital with an acute respiratory condition, or acute worsening of their chronic lung condition. This will enable identification of predictors of future risk, as well as develop potential interventions targets.
This study is designed to test the efficacy and safety of combinations of two well-understood agents - famotidine and celecoxib in patients hospitalized with moderate-to-severe COVID-19 (based on World Health Organization [WHO] Ordinal Scale for Clinical Improvement). Both famotidine and celecoxib separately demonstrate clinical activity in mitigating COVID-19 disease symptoms or severity, and appear to have separate and complementary mechanisms of action.
Non-Invasive Positive Pressure Ventilation (NIPPV) provides un-synchronized positive pressure and considered to be superior to nCPAP in preventing extubation failure. Recently, Non-Invasive Ventilation Neurally-Adjusted Ventilatory Assist (NIV-NAVA) was introduced to NICU. NAVA is a ventilation mode that uses the electrical activity of the patient's diaphragm (Edi-signal) to guide both timing and magnitude of the support. However, it is unknown whether NIV-NAVA is superior to NIPPV in preventing extubation failure and preventing BPD. Hence, the investigators aim to compare the effect of NIPPV and NIV-NAVA on diaphragm function in premature infants with RDS or evolving BPD. Our hypothesis is that infants treated with NIV-NAVA will have improved diaphragmatic function and lung scoring.

This master protocol serves as a common reference for the inpatient and outpatient clinical studies that share common elements.
The objective of this study is to determine whether oral NAC is effective at attenuating COVID-19 disease symptom severity and duration of symptoms.
