The purpose of the study is to describe the rate of occurrence of clinical diagnosis of acute respiratory infection (an infection that affects normal breathing) and different types of respiratory pathogens (harmful organisms) of new respiratory infections in a population at high risk for severe illness.
This is a future-proof and randomized controlled clinical study on the clinical efficacy of graphene photothermal adjuvant therapy in Corona Virus Disease 2019(COVID-19) patients with mild symptoms. The objective is to examine the effect of graphene photothermal adjuvant therapy on the time line for such Corona Virus Disease 2019 patients to achieve a negative severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid test result, and their duration of disease. Patients who meet study criteria will be randomized into the Grapheme adjuvant therapy combined with conventional therapy group (treatment group) and the conventional therapy only group (control group). Contrasted to the control groups, the treatment groups will undergo 30-min of graphene adjuvant therapy every day for 7 d.
Primary Objective: -Estimate the hospital-associated healthcare resource use (HCRU), and associated costs, of RSV infection in children in comparison to the non-RSV control cohort (general population) and patients with rhinovirus infection. Secondary Objectives: - Describe demographic and clinical patient characteristics of RSV infected children. - Estimate and compare the incidence of RSV infection and acute respiratory infections (ARIs) in children. - Estimate the mortality associated with RSV infection in children. - Estimate the social economic burden of RSV infection in children in relation to parents staying home from work to care for their sick child (VAB leave) in comparison to non-RSV control cohort (i.e. parents to children in the general population). - Estimate the net days with VAB leave and the compensation disbursed (temporary parental benefit) associated with RSV infection in children. - Estimate the indirect costs that can be attributed to VAB leave. - Examine the medium- and long-term complications associated with an RSV diagnosis in children in comparison to the non-RSV control chart (general population) and patients with rhinovirus infection. - Examine and describe risk factors associated with an RSV infection in children - Estimate the healthcare resource use (HCRU), and associated costs, of RSV infection in children, for a subset of patients where primary care data is available, in comparison to the non-RSV control cohort (general population).
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.
The goal of this interventional study is to evaluate the pharmacokinetics, safety, and tolerability of 101-PGC-005 in healthy, adult, human subjects. The main question it aims to answer is what are the single and multi-dose PK properties of 101-PGC-005 in the systemic circulation Participants will receive a bolus injection of 101-PGC-005 administered intravenously once daily for 3 consecutive days. Blood and urine samples will be collected at predetermined timepoints for analysis.
Xlear have developed and patented a xylitol containing nasal spray for the treatment of upper-respiratory tract infections. The nasal spray is comprised of xylitol and GSE (Grapefruit Seed extract) which provides antibacterial properties as well as preventing viral adhesion in the nasal passage. Studies into Xlear's antiviral effects on SARS-CoV-2 are currently ongoing but hypothetically, a Xylitol Based Nasal spray may prove to be a useful and inexpensive treatment for COVID-19 infection.
The BK virus (BKV) belongs to the Polyomaviridae family. The primary infection, generally asymptomatic, occurs during childhood. The virus then persists in latent form in the body, mainly in the epithelial cells of the kidney and urinary tract. Cellular immunosuppression favors BKV replication. It is responsible for pathologies of the renal-urinary tract such as BKV-associated nephropathy (BKVAN) in kidney transplant recipients, hemorrhagic cystitis (HC) in hematopoietic stem cell (HSC) recipients or ureteral stenosis. To date, there is no specific antiviral treatment against BKV. The management of patients is essentially symptomatic and requires a multidisciplinary approach. It is therefore necessary to identify early prognostic markers for the occurrence of CH and to develop new therapeutic strategies.
The SARS-CoV-2 (Severe acute respiratory syndrome coronavirus type 2) infection was in 2020 responsible for new disease related chronic conditions which have been referred to as Post-COVID. To date it is still unknown how common this condition is and how it might effect the working of the Immune system. The aim of the study is therefore to monitor the onset of autoimmune diseases in a large observational study consisting of German health insurance data.
Kidney transplant recipients are at increased risk of infections, including Varicella-zoster virus (VZV) infections. Vaccination against VZV is routinely offered to all kidney transplant recipients and candidates in Denmark. In this exploratory observational study, the VZV specific immune response in kidney transplant candidates and recipients will be characterized at different time points in relation to transplantation, vaccination and infections. More knowledge on the immune reaction to transplantation, VZV vaccination and VZV infections may provide improved strategies for prevention and treatment of VZV infections in kidney transplant candidates and recipients.
