Active clinical trials for "COVID-19"

Background: In 2019, a novel coronavirus (SARS-COV2) was detected in Wuhan, China as a cause of acute respiratory distress syndrome (COVID-19). Other previous coronaviruses (SARS and MERS) have caused respiratory sequelae (pulmonary fibrosis) demonstrable by tomography and lung function tests. These alterations have begun to be detected in patients who have survived COVID-19. Hypotheses: SARS-COV2 infection accelerates the deterioration of lung function in patients with Chronic Obstructive Pulmonary Disease (COPD). Objectives: To analyze the evolution of lung function in COPD patients diagnosed with COVID-19, while comparing it with COPD patients without COVID-19 disease. Methodology: Cohort study. The COPD-COVID-19 cohort will consist of the COPD population with and without COVID-19. Previous pulmonary function data will be collected and 2 prospective visits (baseline and follow-up) with clinical assessments and functional tests will be performed. In the event that the participant suffers from COVID-19 during the follow-up, an additional visit will be performed 3 months after the diagnosis, and the final visit will take place 12 months after this additional visit. Determinations: Study factor: diagnosis of COVID-19. Response variable: change in the forced expiratory volume in the first second (FEV1) measured at the start of the study and after 1 year of this first assessment, considering also the basal FEV1 (before March 2020). Other variables: socio-demographic, clinical, functional and treatment. Expected results: Greater decrease in FEV1 in COPD patients with COVID-19, Applicability and Relevance: The proactive detection of functional sequelae will allow early treatment, including pulmonary rehabilitation, with the aim of improving the quality of life of these patients.

The present prospective cohort study aims to assess factors associated with of one-year health-related quality of life and physical, cognitive and mental health outcomes among adult patients with mild COVID-19. Adult patients with symptomatic COVID-19 not requiring hospitalization will be followed through structured and centralized telephone interviews performed at 1, 3, 6, 9 and 12 months after enrollment.

Respiratory failure associated with Covid-19 can be expressed as acute respiratory distress syndrome (ARDS), which is an acute inflammatory lung injury,which generally requires the use of invasive mechanical ventilation (MV). There are inconclusive results regarding the potential lung recruitment in ARDS. Recently, a new index based on lung compliance has been described to directly quantify the potential for lung recruitment, called the recruitment-inflation index (R/I index). The objective of this study is to prospectively evaluate the recruitment capacity in patients with ARDS and ARDS-Covid-19.

The diaphragm is the fundamental muscle of the respiratory system. The diaphragmatic dysfunction is present in 60% of critical patients at hospital admission and up to 80% after prolonged mechanical ventilation and difficult weaning. Risk factors associated with diaphragm dysfunction and atrophy are sepsis, trauma, sedatives, steroids, and muscle relaxants. The main pathology characteristics of diaphragm biopsies of mechanically ventilated patients are atrophy and a reduction in contractility, determining an impact on the clinical outcome. Shi et al. found a higher section area of the diaphragm muscle fiber in biopsies of post mortem COVID-19 patients versus negative patients, independently from days of mechanical ventilation. The hypothesis of our study is to identify different clusters of pathological presentation in post-mortem COVID-19 mechanically ventilated patients.

To accurately describe the rehabilitation needs of individuals with post-COVID-19 syndrome up to 36 months after infection, allowing better diagnosis, triage and resource management. A major focus will be the impact on everyday life to return to normal activities.

During covid-19 pandemic an huge reorganization of all PiacenzaHospital was done to manage the increasing requests for hosptitalization. New nurses had to face first work experience in full pandemic Emergency. Altough even before the pandemic, being a newly graduated nurses was described as a stressful and isolating experience , we can't find studies in the literatureconcerning newly graduated and newly hired nurses during the pandemic pediod. The study purpose is to describe and analyze, trough a phenomenological research, the experience of these nurses.

DM2 is a major comorbidity of COVID-19. It has been observed that subjects with DM2 require more medical interventions, have a significantly higher mortality (7.8% versus 2.7%) and injuries of multiple organs that the individuals not diabetics. In situations of glycemic variability, phenomena of oxidative stress and activation of protein kinase C can be initiated , through the release of pro-inflammatory cytosines , which could induce microvascular damage .Patients with diabetes and COVID-19 were shown to be more likely to develop serious or critical illness with more complications, and to have higher incidence rates of antibiotic therapy, non-invasive and invasive mechanical ventilation, and death (11.1% vs. 4.1%).

This study aims to To study the prognostic value of LUS in COVID-19 patients. To assess the relation between Lung Ultrasonography Score and disease severity in COVID-19 Patients. To assess the relation between Lung Ultrasonography Score and mortality in COVID-19 patients.

The overall aim of this study is to measure how transmission of COVID-19 occurs in communities - including the role of super spreaders and/or identifying conditions that may increase transmission risk, with a focus on congregant situations. In order to identify how presence of symptoms and behavior affects the transmissibility of the virus, the investigators will measure SARS-CoV-2 in exhaled breath of asymptomatic and symptomatic persons using polyvinyl alcohol (PVA) test strips embedded in face masks (Face Mask Sampling- "FMS") - an innovative, non-invasive method for detection of SARS-CoV-2 in exhaled air.

The study aims to characterize the distributive pattern of viruses in upper airway and its relationship with influenza seasons, symptomatology and exposure setting. A total of 500 adults residing in Hong Kong would be recruited, who would complete a questionnaire and return self-collected nasal and throat swabs for metagenomic analyses.
