Filter by:The majority of ICU patients with COVID-19 show profound activation of coagulation, potentially resulting in thromboembolic events. In the treatment of these thromboembolic events it seemed that very high dosages of unfractionated heparin were necessary to achieve therapeutic values of aPTT and anti-Xa levels. The aim of this study is to explore whether heparin dosages are higher in COVID-19 patients compared to non-COVID-19 patients, to determine the correlation between aPTT and anti-Xa values and to explore possible causes for non-correlating aPTT and anti-Xa, including CRP and AT plasma levels.
This study is a multicenter, randomized, double blind, controlled, phase III clinical trial (Immunobridging Study) to evaluate the immunogenicity and safety of Vaksin Merah Putih - UA SARS-CoV-2 (Vero Cell Inactivated) in healthy populations aged 18 years and above. Vaksin Merah Putih - UA SARS-CoV-2 (Vero Cell Inactivated) is an inactivated vaccine made of SARS-CoV-2 virus isolated from a patient in Surabaya, composed with aluminium hydroxy gel, tween 80, and L-histidine, and this study will be the first phase III in human.
This study will be observational only. It will provide real-world evidence generated from a representative and large-scale COVID patient base. The adoption, pilot testing and use of NIH PROs among viral tested patients with research purpose on long COVID will be unique and innovative. With the existing and proven scientific rigor, NIH PRO system will be adopted, then modified and tailored to form the long hauler specific, comprehensive instrument, helping generalize future knowledge regarding COVID-infected patients.
Clinical trial with randomized allocation in two arms (BCG vaccine versus placebo) of volunteers at risk but not yet infected nor vaccinated against SARS-CoV-2. Initially will be evaluated whether BCG has a protective role against severe form of the disease. After participants are vaccinated against COVID-19, it will be evaluated whether BCG favors the vaccine's efficacy. Volunteers will be recruited in three Brazilian states, with at least 250 seronegative in each group. The BCG-trained immunity stimulus will be investigated by assessing cytokines at D0 and D60 in a subsample of 50 participants per group. Until being vaccinated against COVID-19, the participants will be followed for up to 6 months, with visits scheduled every 2 months for interviews and immunoglobulin G (IgG) anti-SARS-CoV-2 antibodies. Those who become symptomatic at any time during the follow-up will be guided and monitored remotely daily until the end of their clinical evolution. After being vaccinated against COVID-19, visits to participants will be adjusted for the time of vaccination (VD), 20 days after the 1st dose (P1) and at least 30 days (P2) after the 2nd dose, with the aim of comparing the efficacy of the anti-SARS-CoV-2 vaccine in the two groups in the short and medium term. The study's conclusions on the efficacy of BCG in preventing severe COVID-19 will be based on: incidence of SARS-Cov-2 infection (defined as the emergence of IgG over the follow-up period); incidence of illness by COVID-19 (defined as the presence of symptoms among infected participants); intensity and duration of symptoms between cases of COVID-19 and frequency and duration of hospitalizations for COVID-19 in each group. The occurrence, type, frequency and intensity of adverse effects associated with vaccination of adults with BCG will be reported. The study's conclusions regarding the effect of BCG on efficacy of vaccines against COVID-19 will be based on: frequency of anti-SARS-CoV-2 neutralizing antibodies after the vaccine' 1st and 2nd doses in both groups.
Jinzhen oral liquid and Jinhuaqinggan Granules were used in the treatment and the control group for 14 days, respectively, to evaluate the effect of Jinzhen oral liquid in treating children with novel coronavirus infection.
The main objective of this pilot study is to evaluate the impact of a self-management intervention using wearable biometric technology on post-COVID-19 syndrome. In addition, this pilot-study will provide information regarding validity, feasibility, patient compliance and satisfaction, valuable for the design of a future large-scale study.
Performance of the LumiraDx SARS-CoV-2 Ag ULTRA assay will be assessed by comparison to a reference method
Background: Currently in the world, 41% of children under 6 months are exclusively breastfed. The Covid-19 pandemic has had a major impact on breastfeeding.; Methods: A statistical analysis of linear regression, prolactin analysis in the 3rd trimester of pregnancy and 15 days 15 after delivery was performed in women with Covid- 19 infection and healthy, finally the rates of 16 breastfeeding were evaluated. The sample was made up of 680 pregnant women from the Valladolid 17 Health Area, central region of Spain.
This Phase Ⅱ/Ⅲ study is to evaluate whether or not there is a difference in time recovery of COVID-19 signs and symptoms through Day 29 between SIM0417/ritonavir and placebo.
The primary objective of the study is to evaluate the safety and tolerability of REGN14284 in healthy participants, as measured by all treatment-emergent adverse events (TEAEs) and treatment-emergent serious adverse events (SAEs). The secondary objectives of the study are: - To assess the concentration-time profile of REGN14284 in serum - To assess the immunogenicity of REGN14284
