Filter by:Prone positioning improves oxygenation in patients with ARDS (1-3). Patients with severe ARDS due to COVID-19 are candidates for prone position. It should be started within 36-48 h and maintained 1, 3). Prone ventilationARDS based on a randomized trial that showed a mortality benefit (PROSEVA) (3). The improvement of oxygenation occurs by making ventilation more homogeneous, limiting ventilator-associated lung injury (4-6). Prone positioning was as effective in improving oxygenation, static respiratory system compliance (Crs) (7). Higher PEEP should be applied when there is a high recruitability potential of the lung. This study aimed to investigate whether prone positioning changes the recruitability position of the lung.in COVID-ARDS.
Vaccination is the best way to mitigate the coronavirus disease 2019 (COVID-19) pandemic, but the vaccine immunogenicity may be quite variable from person to person. There is increasing evidence suggesting that the gut microbiome is a major determinant of vaccine immunogenicity. Thus, the investigators investigated the relationship between gut microbiota and humoral immune response after COVID-19 vaccination.
To investigate the effects of lockdown in the Emergency Department in a tertiary health care hospital, Nuremberg, Germany.
Food supplements like curcumin and boswellia serrata have been used traditionally for anti-inflammatory purposes. A well-known problem of these substances in their natural form is the low bioavailability. Micellization of these substances has been shown to increase the bioavailability significantly and thereby the clinical efficacy. The clinical value of these micellized substances has been presented in numerous clinical studies and in particular in patients with acute COVID-19. This study aims to examine the effect of a mixture of micellized curcumin, boswellia serrata and ascorbic acid on patients with long COVID.
This is a randomized, double-blinded, and positive-controlled Phase IIb clinical trial of COVID-19 vaccine (CoronaVac®) manufactured by Sinovac Research & Development Co., Ltd.The purpose of this study is to evaluate the immunogenicity of using the high (1200SU) or medium (600SU) dose of CoronaVac® as the booster dose.
The primary objective of the study is to characterize the concentrations of casirivimab+imdevimab in serum over time after a single subcutaneous (SC) administration The secondary objectives of the study are: - To assess the safety and tolerability of SC or single administration of casirivimab+imdevimab - To assess the occurrence of grade ≥3 injection site reactions and grade ≥3 hypersensitivity reactions, in participants treated with SC doses of casirivimab+imdevimab - To assess the immunogenicity of casirivimab+imdevimab
Patients with severe Coronavirus Disease 2019 (Covid-19) pneumonia depending on mechanical ventilation are at risk of superinfections, especially infections of respiratory tract. This multicententer prospective observational study is focused on early diagnosis of respiratory tract superinfections and identification of risk factors (immunosuppressive therapy,...). Investigators will use bronchoalveolar lavage fluid (BALF) for Polymerase Chain Reaction (PCR) detection of pathogens and antigenic detection of mycoses. This project can support the routine use of BALF and PCR diagnostics for early detection of pathogens. Data will be compared with historical cohort of patients without routine BAL.
The primary objective is to assess the safety and tolerability of 2 different doses (10 or 30 mcg) of GRT-R910 when administered as a boost in healthy adults previously vaccinated with the AstraZeneca, Janssen/Johnson and Johnson, Moderna, or Pfizer/BioNTech COVID-19 vaccines.
This is a randomized, double-blind, parallel-controlled study, for evaluation of safety and immunogenicity of three doses of an inactivated COVID-19 vaccine (CoronaVac) in pulmonary tuberculosis patients aged 18-75 years. 200 tuberculosis patients and 40 healthy adults aged 18-75 years will be recruited in this study. Of them, 200 pulmonary tuberculosis patients will be randomized at a 1:1 ratio to receive two doses of standard dosage CoronaVac plus one dose of double dosage CoronaVac or two doses of standard dosage CoronaVac plus one dose of standard dosage CoronaVac at a schedule of 0, 28, 56 days, respectively. Other 40 healthy subjects served as an external control group will be vaccinated with two doses of standard dosage CoronaVac at a schedule of 0, 28 days. The occurrence of adverse events within 28 days after each dose vaccination and serious adverse events within 3 months after full vaccination will be observed. In addition, blood samples will be collected on day 0 before the first dose and 28 days and 3 months after the last dose vaccination in all participants and 28 days after second dose in pulmonary tuberculosis patients. Each subject will remain in this study for 5 months (healthy group) or 6 months (tuberculosis group).
To create and evaluate effective COVID-19 testing uptake strategies that focus on underserved individuals who are exposed but have not accessed testing, and underserved individuals who are not routinely tested because they are unaware of their exposure or risk status in order to increase testing among these populations and reduce Covid-19 related disparities.
