Filter by:There is no cure for cold or flu, most people recover in about within two weeks. Paracetamol may be used to reduce aches or treat fever, headache, or body aches. Antiviral solutions ranging from simple universal saline solutions to novel compounds have been proposed to provide a temporary barrier to prevent viral infection and propagation. The nasal spray "Humer Stop Virus" is indicated in patients presented with early symptoms of viral respiratory infection. This spray forms a protective barrier in the nasal mucosa which is the main entry of the upper air respiratory system viruses. The spray traps the viruses and helps the organism to eliminate them before they multiply themselves. This clinical investigation is conducted to assess the performance, clinical benefit and safety of this nasal spray in patients with early symptoms of acute respiratory disease whether or not infection is related to common cold, flu or COVID virus. Indeed, presence of early symptoms of acute respiratory infection does not always imply viral infectionAntigen self-tests are available to confirm viral infection with flu viruses or severe acute respiratory syndrome (SARS-CoV-2). However, influenza and other winter viruses are not systematically searched for in general population, because this is of neither collective nor individual interest. To be as pragmatic as possible, we chose to assess performance and safety of the nasal spray on intended users in real conditions. Patients with early symptoms of cold, flu or COVID, are enrolled regardless their PCR test positivity confirming viral infection at the time of enrollment. For study needs, the primary endpoint, which aims to assess the performance of the nasal spray in terms of stopping the viral infection, is assessed in a subgroup of patients with a positive PCR test with flu, COVID or common cold virus in the nasal sample collected at enrollment.
The purpose of the protocol is to study the pulmonary microbiome in patients who develop pneumonia.
The study titled " The Effect of Definitive Identification of Viral Etiology in Emergency Department Patients with Acute Respiratory Infection on Antibiotic Utilization (RADIATE)" aims to investigate the effectiveness of a rapid diagnostic approach in reducing unnecessary antibiotic use in the emergency department (ED) for patients presenting with acute respiratory illness (ARI) due to a virus. Using a prospective design, eligible participants are individuals who visit the ED with complaints related to acute respiratory illness. The study will employ a single-arm consecutive enrollment approach. The intervention involves the implementation of a rapid point-of-care multiplex polymerase chain reaction (PCR) test to promptly identify the viral cause of the infection. By utilizing a rapid diagnostic tool to identify viral etiology, the study aims to provide healthcare professionals in the ED with more accurate information to guide treatment decisions. Ultimately, the goal is to decrease the unnecessary use of antibiotics for ARI's due to a virus, which has several negative outcomes including promotion of antibiotic resistance, exacerbating ED length of stay and encouraging unnecessary additional diagnostic tests.
This is a prospective observational study using whole genome sequencing (WGS) to investigate whether new strains (other than the initially identified strain(s)) of M. avium are responsible for persistently culture positive sputum during treatment (refractory disease), or the reversion to culture positive sputum after prior conversion to negative. The study will further investigate for differences between participants living in the Toronto/York region versus participants living elsewhere. The primary goal of this prospective observational study is to understand why some patients with M. avium lung disease have persistent or recurrent M. avium in their sputum despite treatment. The aim is to understand whether it is usually due to treatment failure or new infection.
This study was set up because of an unusual increase in the number of cases of mycoplasma infections in France between June and November 2023. Clinical data from children with mycoplasma infections will be collected to characterise this infection and facilitate hospital management.
Severe bacterial infections are a worldwide scourge. However, the epidemiology of this type of infection varies over time. It is therefore essential to monitor them in order to prevent them more effectively. At this time, in France, no monitoring exists for this kind of infections.
The goal of this observational study is to investigate how bacterial populations from the intestine and mouth of patients change during the hospitalization period and evaluate if some populations of specific bacteria increase or decrease the risk of acquiring an infection or becoming colonized by pathogenic bacteria. Participants will have the following samples collected during enrollment: stool samples (maximum 2x/week), blood draws (1x/week), oral swab (1x/week).
Through contact with peers in daycare and (primary)school young children play a large role in spreading respiratory pathogens. In this study the investigators will investigate this transmission, the subsequent colonization and infection dynamics, and their association with clinical symptoms and local immune response through dense minimally-invasive sampling. This study will allow us a unique insight into the transmission-, infection-, and colonization-potential of the respiratory pathogens.
The purpose of this study is to evaluate the safety and immunogenicity an investigational messenger ribonucleic acid (mRN)A vaccine for the prevention of lower respiratory tract disease (LRTD) caused by respiratory syncytial virus (RSV) and/or human metapneumovirus (hMPV) in older adults. A single intramuscular (IM) injection of 3 to 4 different doses of the RSV/hMPV mRNA vaccine candidate formulated with 2 different lipid nanoparticles (LNP) will be administered to healthy participants aged 18 to 49 years and 60 years and older. Treatment: - RSV/hMPV mRNA / LNP 1 at 3-4 different doses or, - RSV/hMPV mRNA / LNP 2 at 3-4 difference doses or, - RSV mRNA / LNP 1 at 1 dose or, - hMPV mRNA / LNP 1 at 1 dose
Obesity is a life-threatening disease, defined by excessive fat accumulation that increases the risk of other diseases such as cardiovascular events, hypertension, diabetes and cancer. Obesity is also a risk factor for nosocomial infections and is associated with worse COVID-19 outcomes, although anthropometric measurements are not routinely recorded during hospitalization and lack of a registry data does not allow performing retrospective studies.Obesity is closely related to chronodisruption, characterized by deregulation of physiological and behavioral central and peripheral circadian rhythms contributing to the obesity-related metabolic impairment. Eating and sleeping time schedules are relevant synchronizers of humans' biological clock. Several studies suggest a role of dietary interventions in rewiring the circadian rhythm, with Mediterranean diet (MD) regulating nutritional patterns. Moreover, considering its positive impact on sleep quality, melatonin intake was suggested as a potential regulator of circadian rhythms. The relation between chronodisruption, obesity and infections has not been investigated, and a first proof of concept (Pilot study) will aim at investigating it. Three cohorts of obese patients with different aetiology (essential obesity, obesity with type 2 diabetes, genetic forms of obesity) and a cohort of lipodystrophic patients will be enrolled in the study, which is designed as a two-phases protocol. During the first phase (0-12 weeks (w)) patients will be subjected to dietary intervention with hypocaloric MD; in a second phase (12-24w), melatonin 1mg/die before sleep will be added to the hypocaloric MD. The susceptibility to infections will be investigated through the evaluation of 1) the number of events - i.e. flu- or flulike syndromes, skin, respiratory, digestive, urinary infections-per patient of the 4 groups and the blood assays to detect the infection with Epstein-Barr, Cytomegalovirus, Varicella, Measles and SARS-CoV-2 IgG and IgM; hepatitis C and hepatitis B core antibodies and Quantiferon TB Gold, 2) the clock genes rhythm and TLRs expression in patient immune cells at baseline, 12w and 24w.The mutual relationship between biomedical values, environmental and social conditions, and lifestyle habits will be evaluated by structured questionnaires. Validation of questionnaires to explore the susceptibility to infections is another delivery planned for the current study.
