Filter by:This first-in-human clinical trial is designed to evaluate the safety and immunogenicity of one administration of OVX033 coronavirus vaccine at different dose levels (100µg, 250µg and 500µg)
The patients with coronavirus infection usually have fever, respiratory symptoms, headache, toothache, muscle soreness, physical decline, and so on, while others are asymptomatic patients. It is urgent to find drugs to improve the long-term rehabilitation of symptomatic patients with coronavirus infection and decrease the duration of viral shedding in both symptomatic and asymptomatic patients. This study aims to investigate the efficacy and safety of Lianhua Qingwen capsules in patients with coronavirus infection. The duration of viral shedding and symptoms before discharge, as well as the negative conversion ratio and disappearance ratio of main symptoms after 7-day treatment, will be evaluated. 6-month follow-up will be performed to evaluate the effect of Lianhua Qingwen on all infection events and the long-term rehabilitation of the symptoms induced by coronavirus infection.
The patients with Omicron infection usually have fever, respiratory symptoms, tachycardia, headache, toothache, muscle soreness, physical decline, and so on, while others are asymptomatic patients. It is urgent to find drugs to improve the long-term rehabilitation of symptomatic patients with Omicron infection and decrease the duration of viral shedding in both symptomatic and asymptomatic patients. This study aims to investigate the efficacy and safety of Lianhua Qingke tablets in patients with Omicron infection. The duration of viral shedding and symptoms will be evaluated. 6-month follow-up will be performed to evaluate the effect of Lianhua Qingke on long-term rehabilitation of all symptoms induced by Omicron infection, as well as infection events.
Citizens who undergo testing for COVID-19 at one of two Testcenters in Copenhagen Captial Region will be invited to participate in the study. The participants will be randomized to either an oropharyngeal swap including the palatine tonsils OR an oropharyngeal swap without the palatine tonsils for SARS-CoV-2 testing. The swabs will be sent to the clinical microbiology laboratory for SARS-CoV-2 detection using RT-PCR. The diagnostic accuracy and SARS-CoV-2 viral load will be compared. The participants will be asked to complete a questionnaire regarding their symptoms.
Background: Influenza and coronavirus have been repeatedly causing pandemic recently. Like the Influenza A/H7N9 virus has caused five epidemics in China since its first detection in East China in 2013. In 2017, the previously low pathogenic avian influenza (LPAI) H7N9 virus underwent mutation in its haemagglutinin to give to a highly pathogenic avian influenza (HPAI) virus causing 32 human cases and potentially poses a threat to animal and human health. More recently, the SARS-CoV-2 pandemic has been heavily affecting the world. Therefore an effective risk assessment platform is urgently required for better pandemic preparation. Hypothesis: The tissue tropism and pathogenesis of a newly emerged infectious viruses, like the highlypathogenic influenza, like H7N9 and coronavirus, like SARS-CoV-2 would be different from that of their low pathogenic subtype and it would infect and replicate the human respiratory system more efficiently. Because of its resistance to oseltamivir for influenza and no effective antiviral for coronavirus, investigators therefore propose to set up an novel and effective risk assessment platform for emerging infectious viruses. Experimental Design: The tissue tropism and viral replication kinetics of a HPAI and LP influenza and coronavirus will be determined in ex vivo cultures of human brain and compared with their LP subtype. The replication competence and innate immune responses of influenza and coronavirus will be studied and compared with other LP virus in in vitro cultures of human brain cells and human microvascular endothelial cells (HMVEC) both isolated from human brain tissues. Expected outcomes: HPAI influenza and coronavirus particularly SARS-CoV-2 will infect and replicate the human brain tissues and cells more efficiently than their LP subtype. Besides, HPAI influenza and SARS-CoV-2 will induce dysregulated host innate immune response than the LP subtype.
COVID-19 is an infectious disease which presents a heterogenous clinical presentation. Recent investigations suggest that people who were infected by COVID-19 often develop physical disabilities (i.e. pain, fatigue), neurological complications and and mainly disorders of the respiratory system, such as respiratory muscle weakness after hospital discharge. Many therapeutic approaches such as transcranial direct current stimulation (tDCS) have been proposed to minimize functional and structural impairments. The aim of the present study is to evaluate the effects of inspiratory muscle training associated with stimulation of the diaphragmatic motor cortex through hd-tdcs in post-COVID-19 patients on inspiratory muscle strength, pulmonary function, inflammatory levels and functional capacity.
COVID-19 is an infectious disease which presents a heterogenous clinical presentation. Recent investigations suggest that people who were infected by COVID-19 often develop physical disabilities (i.e. pain, fatigue) and neurological complications after hospital discharge. Many therapeutic approaches such as transcranial direct current stimulation high definition (HD-tDCS) have been proposed to minimize functional and structural impairments. Recently, I electroencephalogram (EEG) has been used as predictor of HD-tDCS effectiveness in diverse neurological populations. However, evidences about this tool utilization as efficacy predictor of tDCS in COVID-19 people rest inconclusive. Thereby, our objective is to evaluate HD-tDCS efficacy on fatigue, pain and functional capacity of patients with COVID-19 chronic.
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.
Chinese herbal medicine Jing si herbal tea can effectively reduce the expression of SARS CoV2 in the throat of infected patients, provide medical discoveries, formulate effective isolation policies of hospitals and homes, count the virus retention, develop effective medical care and protection of medical personnel, and create a win-win situation.
Due to Covid-19, intensive care (ICU) patients are not allowed visitors or have severely restricted visiting. After being admitted to ICU most patients are unconscious or extremely weak and therefore cannot speak on a phone or video call to a family member. Before these visiting restrictions, family members of patients admitted to ICU as a result of being critically ill were already known to suffer significant psychological distress and may now face increased distress given they are unable to visit a loved one. Previous research demonstrates that keeping a paper diary has been found to be helpful for ICU patients and families. When lockdown measures were announced, NHS Scotland introduced video diaries as an emergency measure to try to support communication with families and reduce distress. vCreate is an NHS Trusted secure video messaging service that helps patients, families and clinical teams stay connected throughout their care journey. The use of video diaries may have a positive impact for family members but there is a risk that they could also have negative effects for some people. There is a need to explore both ICU healthcare professionals and family members' experiences of using video diaries. At the same time it is also important to test the feasibility and acceptability of measures of distress and psychological well-being on family members during and after their experience of video diaries. In doing so, some initial recommendations about video diaries can be made and a larger subsequent study planned to test their effect on family members and healthcare professionals.
