Current virus detection methods often take significant time or can be limited in sensitivity, specificity or cost. There is therefore a need for diagnostic methods that are simple to use, sensitive, rapid and inexpensive. This is a proof of concept study to determine whether the OxDx system (a new a rapid pathogen identification technology) is able to detect and differentiate different viruses from nasopharyngeal swabs/aspirate specimens. The data collected will be used to "train" the algorithms to be able to accurately identify respiratory viruses. The accuracy with which the algorithms estimate the test dataset will be monitored at regular intervals during the training dataset collection period. The OxDx system is still under development, which means that it is still "learning". The system needs to see more information so that it can be sufficiently accurate to be used in clinical practice and should become more accurate in identifying these viruses as it sees more and more information from patients. This study will take place at Portsmouth Hospitals University NHS Trust and aims to recruit 1000 patients. To do this, we will recruit both adults and children who either present to the emergency department or are admitted to QAH with a clinical suspicion of a respiratory viral infection. All participants will have a nose and/or throat swab taken as part of their clinical assessment, and we would ask to take a further nasal swab for the purpose of the study. Research sampling will be combined with routine clinical samples where possible to reduce the frequency of testing. We will use most of the information to teach the system how to become more accurate at identifying respiratory viruses. We will keep the remaining information separate and use it to test how accurate the system is. All of the data will be kept securely. Basic information will be collected including age, gender, results of blood tests taken for clinical review, treatment and outcome data. No results from the swabs taken for the purpose of the study will be available to either the participant or the clinical team and the information will have no effect on patient care.
The purpose of this study is to detect the efficacy of intranasal dexmedetomidine as a premedication to general anesthesia in pediatric patients with respiratory comorbidities undergoing adenotonsillectomy.
This study aims to evaluate the diagnostic and prognostic performance of a novel mRNA diagnostic/prognostic classifier (interprets the expression of 29 host response mRNA biomarkers) from whole blood in adult patients presenting to emergency departments (ED) with suspected infection.
Streptococcus pneumoniae infections often cause serious health problems, especially in infants and the elderly. Failure to cover all polysaccharide types of vaccines is a greater problem for adults than for children. The purpose of this study was to preliminarily evaluate the safety and immunogenicity of a recombinant pneumococcal protein vaccine applied to adults aged 50 years and older to provide a basis for subsequent clinical trial design.
This is a multicenter, ambispective observational cohort study. The patients with corona virus disease 2019 (COVID-19) will be included in the study. The patients will be divided into 4 groups according to the treatment mode (Azvudine treatment group within 48 hours after the first positive for nucleic acid, Azvudine treatment group after 48 hours after the first positive for nucleic acid, short course of Azvudine treatment without nucleic acid turning negative, and the control group) . This study aims to analyze the efficacy and safety of Azvudine in the treatment of patients with COVID-19.
The Belgian Severe Acute Respiratory Infections network (BELSARI-net) was implemented during the influenza season 2011-2012 following the recommendations of the World Health Organization (WHO) to monitor severity of influenza viruses in hospitals. The network is composed of 6 hospitals throughout the country, two in each administrative region (Flanders, Wallonia and Brussels-Capital), and operates during the influenza epidemic period (from the last week of December or first/second week of January to the third/last week of April, depending on when influenza virus circulation is detected by the general population, based on the Influenza-like illness (ILI) network of general practitioners). Enrollment is performed for all cases matching the SARI case definition (based on WHO's case definition) and accepting to take part. A respiratory specimen is sampled systematically from each participant, and detailed clinico-epidemiological data, such as information on age, sex, symptoms and potential risk factors such as pregnancy or comorbidities (chronic respiratory diseases, asthma, chronic cardiovascular diseases, renal insufficiency, obesity, diabetes, hepatic or renal insufficiency, immunodeficiency, neuromuscular disease, pregnancy) is also collected. Participants are followed up during hospitalization for the occurrence of complications (detection of pneumonia based on chest radiography, development of acute respiratory distress syndrome (ARDS), requirement for respiratory assistance and/or for extracorporeal membrane oxygenation (ECMO), admission in intensive care unit (ICU)), or death (all-cause death). The current project includes all the samples received by the Belgian National Influenza Centre (NIC) during the influenza seasons 2011-2012 till 2019-2020.
Approximately 8% of all births occur between 30-36 weeks of gestation ('moderate-late' prematurity). Respiratory tract infections (RTI) and wheezing illnesses disproportionally affect preterm infants resulting in a 1.5-2 fold higher hospitalisation rate during the first years of life compared to term born children. Besides prematurity, several other postnatal modifiable influencing factors are associated with increased risk of respiratory morbidity and impaired pulmonary development. These factors include RTI, rapid weight gain, air pollution, tobacco smoke exposition, vitamin D deficiency, maternal stress and antibiotic usage. The investigators hypothesize that a follow-up program aiming at prevention of modifiable influencing factors can reduce respiratory morbidity in moderate and late prematurity. Objectives: To reduce respiratory disease burden in moderate-late preterm infants in the first 18 months of life
The goal of this observational study is to describe the immune signature of acute pulmonary infection.The main questions it aims to answer are: 1. Nasal mucosal immune response in patients with influenza infection 2. Difference of immune response between Viral sepsis and Bacterial sepsis 3. Immunological differences between Viral sepsis and Viral pneumonia
The present study aims to evaluate how commonly diagnostic tools employed in the preoperative evaluation of respiratory function in thoracic surgery can identify pathological alteration due to a previous SARS-CoV-2 infection. In particular, the investigators will gather information concerning imaging (lung ct and lung ultrasound), arterial blood gas analysis, and pulmonary function tests.
