Filter by:The current Coronavirus Disease 2019 (COVID-19) pandemic continues to be a worldwide health emergency. To contain the spread of disease, high demands on testing availability and capacity are observed. Although polymerase chain reaction (PRC) is the golden standard method in detecting infection with COVID-19, the procedure is time consuming and requires healthcare personnel and laboratories. Rapid antigen tests, however, have several potential benefits including greater scalability and results are provided much quicker. So far, sampling for rapid antigen tests is predominantly performed by health care personnel. Though, the testing and analyzing procedure of an antigen test seems manageable by laymen but the validity of a self-performed rapid antigen test is sparsely examined. Thus, the investigators wish to conduct a study evaluating the diagnostic accuracy of self-performed rapid antigen test for detecting COVID-19 infection by comparing self-performed and healthcare-performed rapid antigen tests on the same individual while using a PCR tests as a control.
This is an open-label, dose-escalation phase I study to assess the safety and tolerability of siCoV/KK46 in healthy volunteers. The purpose of this study is to determine the maximum daily dose of siCoV/KK46 as a single agent in adult healthy participants. Based on preclinical data from this institution, the investigators hypothesize that SARS-CoV-2 inhibition with siCoV/KK46 could potentially reduce pulmonary inflammation, thereby improving COVID-19 patient outcomes.
COVID-19 is an acute respiratory disease caused by Severe Acute Respiratory Syndrome coronavirus (SARS-CoV). Synairgen is currently conducting a global Phase III clinical trial of SNG001 to determine efficacy and safety in patients hospitalised due to COVID-19 that receive oxygen therapy. The primary endpoint in the Phase III trial (SG018) is to evaluate recovery in patients hospitalised due to COVID-19 that require oxygen therapy after administration of SNG001 compared to placebo. The primary endpoint will be determined using the World Health Organization Ordinal Scale of Clinical Improvement (OSCI) score, which will be assessed daily. The OSCI will be used in two different ways during SG018. When the patients are in hospital, the clinical study staff will assess the patient via observation using the OSCI. However, when patients have been discharged from hospital, the clinical study staff will assess the OSCI by asking two questions, one regarding the presence of COVID-19 symptoms and the other regarding usual activities returning to baseline levels. The patient will be required to answer both questions with either a 'yes' or 'no' answer. Daily assessments of the OSCI will be conducted via video call or telephone call after discharge from hospital. The two questions asked of patients when OSCI is assessed after discharge from hospital have been added to trial SG018 to allow assessment of OSCI to continue throughout the trial. As these are new questions and the data from these is being used to assess the primary endpoint in trial SG018, their relevance, ease of understanding and clarity needs to be shown, which is why this interview study is being conducted. Having patients comment on these questions will ensure that the way the benefit of treatment is being measured in SG018 is done in a robust and patient-centred way. The main aims of this qualitative pilot study are to: 1. To confirm how relevant, clear and easy to understand the two additional OSCI questions asked about COVID-19 symptoms and levels of usual activity are when patients have been discharged from hospital. 2. To find out what other symptoms and experiences patients hospitalised for COVID-19 might have had to see if these are reflected in the questionnaires used in SG018.
This is a Phase II study with single-blinded safety phase followed by double-blinded randomization, placebo-controlled, of administration of a single dose by two different administration routes (intramuscular route or intranasal route), to evaluate immunogenicity and safety of the recombinant SARS-CoV-2 vaccine (AVX/COVID-12 vaccine) based a live Newcastle disease viral vector (rNDV) in 396 healthy subjects with evidence of prior immunity to SARS-CoV-2, followed by a booster response assessment with an intramuscular dose of COVID-19 vaccine (ChAdOx-1 -S[recombinant]) in subjects originally randomized to the placebo arm at several research sites in Mexico City.
COVID-19 cases are rising substantially in Jordan. Since this is a novel virus, there is still much to be investigated surrounding its pathophysiology in order to attempt to find suitable treatments or better decision-making in the prognosis of the disease. This project aims to identify if soluble angiotensin-converting enzyme (ACE2) can be used as a prognostic factor for COVID-19 severity, which will allow clinicians to manage COVID-19 cases more efficiently. ACE2 is of interest since the coronavirus enters host cells through ACE2 receptors. It can slo be hypothesized that the irus may also bind to soluble ACE2, but without mediating its effects. It si, therefore, expected that those with higher levels of ACE2 would more likely have milder disease. This can potentially help improve survival rate, allowing clinicians to identify the higher-risk patients and monitoring them more closely.
This is a retrospective observational study in the form of a cohort study evaluating the use of pre-operative imaging for the diagnosis of acute appendicitis in a tertiary centre during the first and second waves of the COVID-19 pandemic in the United Kingdom. The study group includes all patients who underwent emergency appendicectomy for suspected acute appendicitis between March 2020 and February 2021, while the control group includes all patients who underwent emergency appendicectomy for suspected acute appendicitis between March 2019 and February 2020. The final histology will be used as primary outcome, as the study hypothesis is that increasing the use of pre-operative imaging will reduce the negative appendicectomy rate.
Canine olfactive detection has proven its efficacy in numerous situations (explosives, drugs, bank notes…) including for early diagnosis of human diseases: various cancers, alert of diabetic or epileptic people in immediate alarm of crisis.
Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has already rapidly spread around the world as a pandemic after its first report in Wuhan, China on December 12th 2019 ( Holshue ML et al .,2019 ). As of December 27th 2020, there were more than 79.2 million confirmed cases and more than 1.7 million deaths caused by COVID-19 worldwide (WHO,2020). Migraine& tension headacheare considered one of the most disabling chronic neurological diseases, and patients with migraine or tension headache are particularly vulnerable to drastic negative impacts of the pandemic. From heightened levels of psychosocial stress, social isolation , disruption of sleep and dietary habits ,to several COVID-19-specific concerns. Normally, people with epilepsy (PWE)patients are very sensitive to different factors such as physical or emotional disturbances or environmental and lifestyle changes.Many factors can increase the risk of seizures,i.e., illness and fever, stressful events, sleep deprivation,changes in antiepileptic drugs (AED),use of proconvulsive treatments,to name a few.Some are unavoidable during a sociosanitary crisis like that currently being experienced. Because of the rapid increase of infections, Government enacted a national state of emergency, limiting public mobility and compelling home confinement and social isolation. This national lockdown, in addition to the direct effects of COVID-19, have dramatically altered the lifestyle and normal routines of the entire population.Therefore, in addition to the risk of neurological involvement that COVID-19 itself has, during the pandemic,different circumstances may negatively impact on seizure control in PWE.
Investigators aimed to evaluate the effectiveness of exercise programs given by synchronous and asynchronous telerehabilitation methods in patients after discharge from COVID-19.
Study objectives: To evaluate the immunogenicity and immunity persistence and safety of recombinant novel coronavirus vaccine (CHO cells) after booster immunization in populations vaccinated with two doses of marketed novel coronavirus inactivated vaccine (CoronaVac). Study method: For the subjects who have been vaccinated with two doses (the interval between two doses ≥ 3 weeks) of the novel coronavirus inactivated vaccine (CoronaVac) for 3 to 9 months, 1 dose of the recombinant novel coronavirus vaccine (CHO cells) was administered. Blood samples were collected before booster immunization, 14 days, 30 days and 180 days after booster immunization for neutralizing antibody detection. All AEs were collected within 1 month after the booster immunization. All SAEs were collected within 6 months after the booster immunization.
