Filter by:The clinical trial studies the human pathogen of SARS-CoV-2, with a specificity in the circulating Spike 2 protein in the human system. The clinical trial hypothesizes that SARS-CoV-2 human pathogen arises from immune attacks, underlying the severe physiological symptoms that can be lethal. It further hypothesizes that the vaccines do not deal with the Spike 2 protein that causes the immune attacks.
Background: CT has been used on a massive scale to help identify and investigate suspected or confirmed cases of COVID-19 pneumonia. This study aimed to assess the prognostic significance of the chest findings MSCT of Covid-19 patients and to determine if prognosis can rely on the initial CT imaging. Methods: The study design was retrospective cohort study. It was carried out on 300 patients presented to the chest outpatient clinics in Benha university hospitals and Elabbasyia chest hospital with clinical picture suggestive of COVID 19 infection. The CT finding were then compared to the short-term clinical outcome of the patients (1-3weeks), acquired from the hospital patient data archive. According to the progression of the respiratory symptoms (include; dyspnea, respiratory rate and O2 saturation), the short-term clinical outcome of the patients was classified into 4 groups; Group A: (mild cases), Group B: (moderate cases), Group C: (sever cases), and Group D: (fatality cases).
An open label, dose escalation, and dose expansion study to evaluate the safety, reactogenicity and immunogenicity of two SARS-CoV-2 DNA plasmid vaccine candidates, VB10.2129 (C1) and VB10.2210 (C2). tThree dose levels will be tested. IM administrations 21 days apart. Part 1 is a dose escalation phase and Part 2 is a dose expansion phase. In Part 2 a selected dose will be tested further in additional healty volunteers.
The aim is to compare the percentage of the different SARS-CoV2 lineages that are detected in wastewater samples with matched clinical samples. About 1,400 swab samples from patients living in Nice were tested by Biogroup between Oct 19th and Oct 23rd (Week 43 of 2020). The sequence of 81 PCR positive samples, corresponding to all samples that were unambiguously assigned to one of the wastewater catchment areas and their lineage was determined. These values were compared to values measured in wastewater.
Unlike other respiratory viruses such as influenza and RSV where the child is the essential reservoir and central vector of intrafamilial contamination, the child is likely to be a small player in the transmission of CoV2-CoRSA infection. This study aims to describe the age category of the first contact, within 14 days before the appearance of the first symptoms of the index case in order to describe the age categories of this first contaminant, globally, in the group of children and finally in the group of adults. This work is intended to provide food for discussion and to justify the distancing and containment measures imposed on children when their isolation has a deleterious impact that has now been established for some children.
The medical charts of all COVID-19 cases (n=1200) from 17 long-term care facilities in Montreal, Canada will be reviewed, to compare patients who survived to patients who did not survive. Through multilevel logistic regression, the risk of death will be estimated for institutional predictors of mortality, while controlling for individual risk factors. Individual covariates include clinical features (age, sex, Charlston comorbidity index, SMAF autonomy score, severity criteria) and medical treatments (IV fluids, anticoagulation, oxygen, regular opiates, corticosteroids). Aggregate covariates include epidemiological data (attack rates, timing of outbreak) and institutional characteristics (number of beds, air exchange per hour, presence of a dedicated COVID-19 unit at the time of outbreak, staff compliance to infection control measures, staff infection rates, understaffing, proportion of semi-private rooms, proportion of wandering wards and other special units).
To present the first admission chest computed tomography (CT) findings of patients followed up with a diagnosis of COVID-19, and to compare the two classification systems by evaluating these findings according to the BSTI and RSNA guidelines.
Unlike other respiratory viruses such as influenza and Respiratory Syncytial Virus (RSV) where the child is the essential reservoir and central vector of intrafamilial contamination, the child is likely to be a small player in the transmission of Severe Acute Respiratory Syndrome CoronaVirus 2 (SRAS-CoV2) infection. This study aims to describe the age category of the first contact, within 14 days before the appearance of the first symptoms of the index case in order to describe the age categories of this first contaminant, globally, in the group of children and finally in the group of adults. This work is intended to provide food for discussion and to justify the distancing and containment measures imposed on children when their isolation has a deleterious impact that has now been established for some children.
Respiratory infections such as colds, flu and pneumonia affect millions of people around the world every year. Most cases are mild, but some people become very unwell. Influenza ('flu') is one of the most common causes of lung infection. Seasonal flu affects between 10% and 46% of the population each year and causes around 12 deaths in every 100,000 people infected. In addition, both influenza and coronaviruses have caused pandemics in recent years, leading to severe disease in many people. Although flu vaccines are available, these need to change every year to overcome rapid changes in the virus and are not completely protective. This study aims to find and develop predictive tests to better understand how and when flu-like illness progresses to more severe disease. This may help to decide which people need to be admitted to hospital, and how their treatment needs to be increased or decreased during infection. The aim is to recruit 100 patients admitted to hospital due to a respiratory infection. It is voluntary to take part and participants can choose to withdraw at any time. The study will involve some blood and nose samples. This will be done on Day 0, Day 2 and Discharge from hospital, and an out-patient follow-up visit on Day 28. The data will be used to develop novel diagnostic tools to assist in rational treatment decisions that will benefit both individual patients and resource allocation. It will also establish research preparedness for upcoming pandemics.
There are still uncertainties about the existence of protective immunity and the duration of protective antibodies in patients infected with SARS-CoV-2. Serological testing is an appropriate tool for epidemiological investigations to assess the persistence of antibodies over time. The nature of the immune response induced by this virus is also poorly understood. This ancillary study aims at assessing the immunological characteristics of patients that participated in the NOSO-COR study at Hospices Civils de Lyon six and twelve months after the initial infectious episode. Two visits will be scheduled at 6 and 12 months (± 1 month) after the initial SARS-CoV-2 infectious episode, Blood, saliva and nasopharyngeal samples will be collected for seroprevalence and immunological investigation.
