Filter by:During the COVID-19 pandemic, testing primarily relied on the use of nasopharyngeal swabs to detect the SARS-CoV-2 virus, responsible for the disease. However, this technique has several limitations, including the variable quality of swabs, its invasive nature, and arbitrariness in the choice of the number of cycles. Furthermore, it does not allow for the detection of viral proteins. To overcome these limitations, researchers developed the eBAM-CoV test, patented for the detection of viral proteins in the exhaled air of COVID-19 patients. This portable device provides an immediate assessment of the "viral load" with both quantitative and qualitative results, showing promise for early virus detection. The researchers hypothesize that the eBAM-CoV test is likely to exhibit a satisfactory concordance with the reference RT-PCR test in the detection of COVID-19, especially among symptomatic patients or closed contacts.
Popular title: Clinical study of Omicron BA.4/5-Delta strain recombinant novel coronavirus protein vaccine (CHO cells). Purpose of the study: Main objectives: To evaluate the immunogenicity and safety of Omicron BA.4/5-Delta strain recombinant novel coronavirus protein vaccine (CHO cells) against the new coronavirus prototype strain and Omicron variant (XBB, BA.5, BF.7) after receiving 2 doses according to different immunization schedules in people aged 18 years and older. Secondary purposes: To evaluate the immune persistence of Omicron BA.4/5-Delta recombinant novel coronavirus protein vaccine (CHO cells) against the new coronavirus prototype strain and Omicron variant (XBB, BA.5, BF.7) after receiving 2 doses according to different immunization schedules in people aged 18 years and older. Overall design: Studies were randomized, double-blind, active-controlled study design. Study group: There were 160 participants aged 18 years and older, including 80 people aged 60 years and older. Study group：Among them, 80 subjects were from the "randomized, double-blind, active-controlled clinical study to evaluate the immunogenicity and safety of Omicron BA.4/5-Delta strain recombinant novel coronavirus protein vaccine (CHO cells) in people aged 18 years and older, protocol number: LKM-2023-NCV-02", 40 cases in the study group and 40 cases in the control group, and completed the second dose of vaccine at the 6th month visit to observe immunogenicity and safety. The remaining 80 subjects were randomly blinded to the 1:1 ratio into the research group and the control group and received 2 doses of the experimental vaccine according to the 0-1-month procedure to observe immunogenicity and safety.
Aerosol Generating Medical Procedures (AGMP) are procedures that have the potential to create tiny particles suspended in the air. These particles can contain germs such as viruses. The Coronavirus Disease 2019 (COVID-19) pandemic was caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Patients infected with SARS-CoV-2 experience unusually high rates of critical illness that needs advanced airway management and intensive care unit admission. Bag-valve-mask (BVM) ventilation, endotracheal Intubation (ETI) and chest compressions are sometimes required for critically ill COVID-19 patients, and may contribute to a high risk of infection amongst Health Care Workers (HCW). To lessen HCW risk during high-risk procedures, a device called an aerosol box has been developed to place over the head of the patient, shielding the provider's face from virus droplets suspended in the air. The purpose of this research study is to better understand how particles disperse during AGMPs, more specifically during the provision of cardiopulmonary resuscitation (CPR). The project team hopes what is learned from the project can help inform infection control measures. This could help make changes to the clinical environment and make it safer for HCW's. The investigators intend to explore how an aerosol box performs in reducing contamination of HCW's who perform critical airway interventions during resuscitation events.
The study aims to investigate the safety and immunogenicity of one dose vs two doses of a T-cell priming next-generation vaccine against Coronavirus disease.
An observational study is carried out in the university population of the University of Salamanca to know the impact of the COVID-19 pandemic and the influence of physical exercise on the severity of symptoms.
Contactless and widely available health monitoring technologies are of growing interest in the context of the worldwide COVID-19 pandemic. Remote photoplethysmography (rPPG) is a well-studied technology that interprets variations in skin colour related to blood flow which, when analysed with complex mathematical algorithm, generates vital sign readings. This technology has been refined and embedded in a smartphone app designed to acquire heart rate, respiratory rate and oxygen saturation using a front-facing smartphone camera. Preliminary data comparing the accuracy of smartphone rPPG readings with conventional vital sign monitor readings are promising; however, less than 5% of the population studied in the app development phase had oxygen saturation levels below 95% making it impossible to ensure reliability in these populations. The goal of this study is to compare readings acquired using this rPPG app with the readings from hospital grade, Health Canada approved vital signs monitors used in healthcare settings with a focus on subject with low oxygen saturations. We will also study other sociodemographic and clinical features that may influence the accuracy of the readings. This will be achieved by recruiting consenting adults presenting to care in acute care settings and a designated COVID outpatient clinic. Vital signs will be acquired using the rPPG app and conventional hospital vital sign monitors simultaneously. Readings will be repeated within 2-5 minutes when time permits. Statistical analysis will be performed to analyze the findings and determine the accuracy and precision of the rPPG app readings. It is expected that the vital sign readings acquired with the rPPG app will be almost identical to those acquired using hospital-grade monitors for all subjects regardless of age, gender, skin colour, COVID status and relevant comorbidities.
- Evaluation of the clinical presentation of COVID 19 pneumonia. - Identification the risk factors of severing COVID 19 pneumonia. - Evaluation of the outcome of the disease.
This is a cohort study of COVID-19 patients with hyperinflammation. It aims to determine the impact of adjunctive Tocilizumab (TCZ) to standard of care on the reduction of hyperinflammation-related mortality in COVID-19. Patients with COVID-19 are at high risk of life-threatening hyperinflammation and death. One in three COVID-19 patients admitted to ICU was found to develop life-threatening hyperinflammation. The risk of death when untreated is estimated to be 50-80%.
Using Laser light to detect COVID 19 virus particles in deep throat swab / nasal swab samples.
The current available diagnostic methods used for the detection of COVID-19 takes up to 4 hours. In some cases, these diagnostics tests make take up to a couple of days. As it is highly contagious, people who are in close contact with the infected person are at high risk of being infected. COVID-19 is transmitted through respiratory droplets produced when an infected person coughs or sneezes. The desire for rapid detection of COVID-19 has become an immediate necessity. The purpose of Kaligia Biosciences' saliva monitoring device (RBA-2) is to detect the presence of the COVID-19 virus in human saliva. The RBA-2 uses Raman Spectros-copy to detect the coronavirus. Once the sample is scanned successfully, the spectra contains the response of the component present in human saliva and provide results in a matter of minutes, rather than hours or days.
