Filter by:The aim of this project is to determine the effect of training given to children aged 11-14 on hand hygiene and mask use. In line with this general purpose, the hypotheses of the research are as follows: H0= Education given to children aged 11-14 on hand hygiene and mask use has no effect on children's hand hygiene and mask use behaviors. H1= With the education given to children aged 11-14 on hand hygiene and mask use, children will exhibit more correct hand hygiene and mask use behaviors.
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 Polymerase Chain Reaction (rRT-PCR) test is still the gold standard in the diagnosis of coronavirus disease. Health workers apply this procedure in a closed area, wearing personal protective equipment. Adolescents cannot be informed about the invasive procedure and it is difficult to communicate with them. Before the procedure, the effect on anxiety will be investigated by watching an informative video (containing information such as the materials used in the procedure, how long the procedure will take, how the sample will be taken, why healthcare workers wear personal protective equipment) prepared according to the developmental characteristics of the adolescents.
This trial is Stage 2 of a 2-part adaptive trial. The study aims to investigate the safety of 2 doses of a T-cell priming specific cocktail of Coronaviruses peptides mounted on a gold nanoparticle. Note: Stage 1 of the 2-part adaptive trial, testing a specifically selected mix of Dengue virus peptides, commenced Aug 2021. This is now in follow up (NCT04935801).
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.
The investigators aim to carry out a retrospective observational study, analysing lung ultrasound images from patients who have presented to A&E for routine diagnostic purposes (ruling out cardiogenic pulmonary oedema, Pulmonary embolism and pericardial effusions) and systematically assessing for abnormalities typical for COVID-19 infection (Pleural irregularities, B lines, consolidations, pleural effusions). Doing this, the investigators will also develop a suggestion for a standardised technique for lung ultrasound which can be transferred to other clinical settings (Intensive Care, Acute medical Unit) and could form the basis for an international standard. Thirdly, the investigators aim to correlate our findings to clinical severity judged by oxygenation status on arrival in ED. To the investigators' knowledge, this is the first study of this kind.
Lung ultrasound has been used to help diagnose COVID-19 as an alternative to CT scanning and chest X-ray. CT scanning is onerous and there are difficulties taking critically unwell patients there as well as decontamination issues. Chest X-ray misses up to 40% of COVID diagnoses. Although lung ultrasound can diagnose, the investigators do not know how long these lung ultrasound changes last. The investigators would like to follow up patients to characterise the pattern of changes and how long they last. This is particularly important given a potential second surge of COVID-19 is looming and the investigators would like to know if lung ultrasound changes are new or old in patients presenting during this second wave and in the future.
