Active clinical trials for "Respiratory Tract Infections"

Performance evaluation of the BinaxNOW™ COVID-19 IgG Rapid Test Device (Professional Use) and with BinaxNOW™ COVID-19 Antibody Self Test wehn used with fingerstick capillary whole blood and plasma samples. The BinaxNOW™ Antibody Tests are lateral flow tests that measure SARS-CoV-2 IgG antibodies.

Influenza is a major cause of morbidity and mortality. The investigators first goal is to evaluate soluble HLA-G5 isoform serum level as a potential marker of greater risk of death from Influenza respiratory illness in adult and pediatric patients hospitalized in reanimation. Secondly, the investigators collected respiratory samples in order to study the transcriptomic profiles of influenza-infected patients with severe symptoms.

The investigators earlier clinical study in 754 young Finnish men demonstrated a significant negative association of serum 25-OHD concentration with acute respiratory tract infections. The present study aimed to determine whether vitamin D supplementation may decrease the incidence of acute respiratory tract infections.

The purpose of this study was to determine whether reduced exposure to indoor air pollution would reduce ALRI incidence in children <18 months of age. Households were randomized to receive a chimney stove (intervention group) or continue using an open fire for cooking and heating (control group).

We hypothesize the herbal preparation will enhance the preschoolers' immune response and when taken prophylactically for 12 weeks will decrease episodes of upper respiratory infections and gastroenteritis in the active versus the control group.

There is a growing body of data suggesting that vitamin D modulates the host's immune response to acute respiratory infection (ARI). The primary aim of this study is to determine whether maternal vitamin D3 supplementation versus placebo decreases the incidence rate of microbiologically confirmed viral-associated ARI among infants in Dhaka, Bangladesh. Secondary outcomes include: A) incidence of ARI associated with specific major pathogens, B) incidence of clinical ARI (without the need for positive microbiology), and C) quantitative density of pneumococcal carriage. Infants will be followed from birth until 6 months of life. Among infants who meet at least one of the specific case definitions for ARI (see 'Detailed Description' section), nasal swab specimens will be collected. Respiratory samples will be analyzed by real-time polymerase chain reaction (qPCR) to identify a 7-virus panel (influenza A and B, respiratory syncytial virus, human metapneumovirus, adenovirus, and parainfluenza types 1, 2, and 3) plus quantitative density of S. pneumonia.

Recurrent respiratory papillomatosis in children caused by HPV 6,11 can be a life threatening condition resulting in surgical interventions. The maturing and disintegrating papillomas are the sources for the subsequent HPV relapses and immunization might slow down or even prevent this ongoing process. After an initial immunological and ear-nose-throat (ENT) assessment children with at least 3 relapses in their patient history will be vaccinated with 4-valent HPV vaccine according to the following schedule: 0., 2., 6. months. It will be followed by an immunological and 3 ENT examinations to assess response to vaccination.

The aim was to study whether probiotic intervention has an impact on seasonal occurrence of upper respiratory and gastrointestinal infections in two different conscript groups. In a randomised, double-blinded, placebo controlled study a total of 983 healthy adults were enrolled from two intakes of conscripts. Conscripts were randomised to receive either a probiotic combination of Lactobacillus rhamnosus GG (LGG) and Bifidobacterium animalis ssp. lactis BB12 (BB12) or a control chewing tablet twice daily for 150 days (recruits) or for 90 days (reserve officer candidates). Clinical examinations were carried out and daily symptom diaries were collected. Outcome measures were the number of days with respiratory and gastrointestinal symptoms and symptom incidence, number and duration of infection episodes, number of antibiotic treatments received and number of days out of service because of the infection. Statistically no significant differences were found between the intervention groups either in the risk of symptom incidence or duration. However, probiotic intervention was associated with reduction of specific respiratory infection symptoms in military recruits, but not in reserve officer candidates. Probiotics did not significantly reduce overall respiratory and gastrointestinal infection morbidity.

The purpose of the study is to determine whether automated cuff pressure control results in a reduction in the proportion of patients developing ventilator associated respiratory infections during their stay in intensive care.

The Frazier Free Water Protocol (FFWP) using plain, thin (unmodified) water is an accepted method to increase fluid intake and hydration in older adults with disordered swallowing and dementia.This study aims to take an interdisciplinary approach to see if the FFWP with improved oral care can be introduced in a long term care (LTC) setting comparing an intervention group with a control group receiving standard oral care, to prevent respiratory infections.
