Filter by:Breath gas analysis is the evaluation of exhaled breath. It aims to evaluate the volatile organic compounds (VOCs) in exhaled breath. In this feasibility study it is intended to find specific peaks/pattern in exhaled breath indicating an infection with SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2).
As a direct consequence of the COVID-19 pandemic, it is assumed that the number of patients with COVID-19-related disabilities will increase significantly. Patients with mild, severe, and critical forms of the disease show long-term sequelae in different systems (respiratory, muscular, psychological, cognitive etc.). Persistent dyspnea is a frequently described symptom after the acute phase of the disease. Coupled with reduced oxygen saturation, an increased risk of developing lung fibrosis has been observed. Specialized rehabilitation medicine (e.g. pulmonary rehabilitation) might counteract these long-term consequences and therefore seems to be a promising approach to treat long-term COVID-19 consequences. Further, there is scarce evidence about COVID-19 specific rehabilitation contents. It was suggested to use treatment regimes in analogy to patients with idiopathic pulmonary fibrosis. There is evidence that pulmonary rehabilitation improves physical performance, quality of life and reduces anxiety and depression symptoms in patients with idiopathic pulmonary fibrosis and other chronic respiratory diseases. Since impairments related to idiopathic pulmonary fibrosis also play an important role in COVID-19, the aim of this study is to evaluate the short and medium-term effects of a standardized 3-week pulmonary rehabilitation program. The results will be analyzed within the two cohorts (mild/moderate and severe/critical COVID 19) as well as between the two cohorts for the primary outcome. Furthermore, the effects of pulmonary rehabilitation will be compared with a retrospective cohort of idiopathic pulmonary fibrosis.
Convalescent plasma has been shown to be safe and effective for treatment of several diseases. Preliminary data indicate that it is safe for treatment of COVID-19. We found that viremia upon admission identifies patients at 7 fold increased risk of admission to intensive care and 8 fold increased risk of death. CP treatment appeared to result in rapid viral clearance in a small case series. CP appeared to be well tolerated in a phase I study in which patients only received one dose of CP and a phase II study in which CP was given until viremia disappeared (unpublished data). Randomised controlled studies assessing the efficacy of CP are lacking and thus the efficacy of CP is unknown. Preliminary data indicate that treatment should be given early, prior to development of severe illness. Detection of viremia upon admission identifies a group at high risk of severe disease and death that has the most to benefit from CP. Phase II study data indicates that treatment should be given until SARS-CoV-2 is no longer detected in serum and the donor antibody neutralization titres should be ≥1/640. A randomised controlled trial in which viremic patients are treated with CP with the equivalent of an antibody titre ≥1/640 is thus required to determine if CP can be an effective COVID-19 treatment.
The goal of the project: to study the dynamics of the humoral and cellular immunity in patients after pneumonia caused by the SARS-CoV-2 virus at different time intervals, in order to predict the duration of immune protection
Some COVID-19 survivors may have respiratory and mental health sequelae, especially those who required hospitalization. The investigators hypothesize that the participation of a rehabilitation program composite by home-based respiratory physiotherapy and telephone-based psychological support will improve respiratory function, quality of life, and psychological status in severe COVID-19 patients.
Pronation seems feasible and effective in improving blood oxygenation in patients with COVID-19 pneumonia. Data are lacking on the effects of pronation on clinical outcome in this subset of patients.
The purpose of this trial is to compare 2 types of nasonasopharyngeal swabs (a new design to a conventional nylon-flocked nasopharyngeal swab) for effectiveness.
Aim of the study was to investigate the effects of the COVID-19 pandemic on individual and general sport activities in an effort to provide information for safe return to community sports.
This is a phase II, randomized, placebo-controlled, observer-blinded study of the safety and immunogenicity of SARS-CoV-2 messenger RNA (mRNA) vaccine (BNT162b2) in Chinese healthy population. After randomization, the trial for each participant will last for approximately 13 months. Screening period is 2 weeks prior to randomization (Day -14 to Day 0), and two doses of either SARS-CoV-2 vaccine (BNT162b2) or placebo will be given intramuscularly (IM) separated by 21 days.
The Investigators want to examine patients infected with SARS-CoV-2 for the phenomenon "Silent Hypoxia", which is clinically significant hypoxia without corresponding degree of dyspnea. The patient population is infected individuals without any serious symptoms and is at home. The participants will be equipped with a pulse oximeter and a PEF-measurement device. Four times daily the participants will register saturation, degree of dyspnea and PEF. If the participants experience desaturation or increasing dyspnea, physiotherapy is to be performed, and if that doesn't relieve symptoms or increase oxygen saturation, the hospital should be contacted for admission. The first part of this study is a feasibility study, and if found feasible, the investigators will expand the study to more participants.
