Active clinical trials for "Respiratory Tract Infections"

Sputum specimens will be obtained from children < 2 years of age and processed by different mode for the HMPV, RSV, Pertussis, Influenza A, B, Parainfluenza 1,2,3, Adenovirus. Clinical and epidemiological data will also be obtained.

Emergency call centers are very solicited in epidemic situations. It is necessary to detect early Predictive Criteria of Severity in COVID respiratory infection to identify patients at risk of complication or aggravation from an emergency call center in order to adapt their orientation and their medical management.

Primary goal of this non-interventional study is to evaluate the change in level of allergen-specific IgE (EAST class) after allergen-specific immunotherapy with Pollinex Quattro with tree and/or grass pollen extracts and their mixtures under medial routine at adults with tree- and/or grass-medicated pollinosis.

The primary objective of this research is to exhaustively document the course and outcomes of hospitalization, labor, delivery, and early postpartum course of up to 15,000 mother-newborn pairs in settings where the occurrence of adverse outcomes is high. The Investigators will gather detailed laboratory, physiologic, and clinical information, and precisely characterize major adverse diagnoses and outcomes. The resulting high-quality, granular, and generalizable data will be used to develop new algorithms to signal actionable intrapartum diagnoses and prospectively stratify women according to their risk for adverse maternal and neonatal outcomes.

The purpose of this study is to validate and standardize bioelectrical impedance analysis (BIA, Maltron BioScan touch i8) for estimating body composition in hospitalized elderly patients with pneumonia. Body composition assessments with BIA and dual-energy x-ray absorptiometry (DXA,

Children in resource-limited settings who develop illness at night are often isolated from pre-emergency care, resulting in progression to an emergency because families are forced to wait until morning to seek care. This is especially true in Haiti based on needs assessments (INACT Part 1; INACT1) surrounding access to healthcare. This study (INACT Part 2; INACT2) seeks to improve access to care by establishing a health hotline (healthline) and mobile pharmacy for families with children who become ill at nighttime. The healthline will be staffed by medical professionals and will provide phone based assessment and treatment recommendations based on standard of care practices according to Haitian and WHO guidelines. The healthline will focus on pre-emergency patients (those without danger signs as defined by WHO guidelines). Emergent patients will be advised to bypass the healthline and seek immediate care at the nearest medical facility. In the event that a non-emergent patient requires access to basic medications or fluids and is logistically accessible, the mobile pharmacy service will be offered. The specific aims of the study are as follows: Aim I. Evaluate congruence between healthline assessment over the phone and in-person assessment of participants (patients using the healthline) 10 years of age and younger. The investigators hypothesize that in-person assessments based on WHO guidelines will be discordant with those made by the healthline because the physical aspects of the call-center assessment will be performed by an untrained parent/ guardian. The study focuses on acute diarrheal disease (ADD) and acute respiratory illness (ARI) but is not exclusive to these two chief complaints. Aim II: Identify determinants that correlate with seeking care at a medical facility over the 8-12 day follow up period after the initial call. The findings from this study will determine if a healthline model is a safe and accurate method of providing high quality access to nighttime healthcare, averting the progression of non-emergent cases to emergencies.

Clinical pneumonia is a leading cause of pediatric hospitalization. The etiology is generally bacterial or viral. Prompt and optimal treatment of pneumonia is critical to reduce mortality. However, adequate pneumonia management is hampered by: a) the lack of a diagnostic tool that can be used at point-of-care (POC) and promptly and accurately allow the diagnosis of bacterial disease and b) lack of a prognostic POC test to help triage children in need of intensive assistance. Antibiotic therapy is frequently overprescribed as a result of suspected bacterial infections resulting in development of antibiotic resistance. Conversely, in malaria-endemic areas, antibiotics may also be "underprescribed" and children with bacterial pneumonia sent home without antibiotic therapy, when the clinical pneumonia is mistakenly attributed to a co-existing malaria infection. The investigators previously identified combinations of protein with 96% sensitivity and 86% specificity for detecting bacterial disease in Mozambican children with clinical pneumonia. The investigators' prior work showed that it is possible to identify biosignatures for diagnosis and prognosis using few proteins. Recently, other authors also identified different accurate biosignatures (e.g., IP-10, TRAIL and CRP). In this study, the investigators propose to validate and improve upon previous biosignatures by testing prior combinations and seeking novel combinations of markers in 900 pediatric inpatients aged 2 months to 5 years with clinical pneumonia in The Gambia. The investigators will also use alternative case criteria and seek diagnostic and prognostic combination of markers. This study will be conducted in Basse, rural Gambia, in two hospitals associated with the Medical Research Council Unity The Gambia (MRCG). Approximately 900 pediatric patients with clinical pneumonia aged 2 months to 5 years of age will be enrolled. Patients will undergo standard of care test and will have blood proteins measured through Luminex®-based immunoassays. Results of this study may ultimately support future development of an accurate point-of-care test for bacterial disease to guide clinicians in choices of treatment and to assist in the prioritization of intensive care in resource-limited settings.

Retrospective analysis with subgroup evaluation Primary objectives of the data analysis study: 1 Retrospective analysis of the symptoms and quality of life data of patients with mild, acute (<96 hours) upper respiratory symptoms based on the results of standard health assessment questionnaires used at the institution, over a period of 10-15 days after the SARS CoV-2 PCR test. Secondary objectives 1 Retrospective assessment of the upper respiratory tract symptoms and quality of life and serological parameters of the contact persons with confirmed close exposure to SARS CoV-2 PCR positive patients (based on the results of the standard health assessment questionnaires used at the institution in the period of 10-15 days after the SARS CoV-2 PCR test) The retrospective analysis also includes an assessment of the pharmacological and supplementary therapies used in patients presenting with mild, acute (<96 hours) upper respiratory symptoms and SARS CoV-2 positive contacts, as well as the incidence of SARS CoV-2 virus infection in contacts confirmed by PCR test (based on values measured within 48 hours and 10-15 days later), and an analysis of patients' serological data.

The aim of this pilot study is to demonstrate the feasibility of viral biomolecular diagnosis in sputum compared to nasopharyngeal swab in cystic fibrosis acute respiratory infection.

This study will analyze gene expression data (HostDx Sepsis test) from blood samples collected from participants with suspected infections. The primary endpoint of the study is to prospectively validate the HostDx Sepsis test for infections. As a secondary endpoint the correlation of participant prognosis and gene expression results in the HostDx Sepsis test will be validated. Participants presenting to the emergency departments of enrolling sites with a suspected infection and 1 vital signs OR suspected sepsis and 2 vital sign changes as stated in the protocol are meeting enrollment criteria
