Filter by:In an effort to implement Choosing Wisely guidelines and decrease patient harm, we will implement and evaluate a clinician audit-feedback and behavioral "nudge" initiative to reduce low-value antibiotics for URIs. Using a quasi-experiment (pre-post) design, antibiotic prescriptions for URI at LAC+USC Urgent Care Center (intervention site) vs. Olive View-UCLA Urgent Care Center (control site) will used to test the effects of behavioral "nudge" on antibiotic prescribing.
The aim of the study is to measure the effect of wheat polysaccharides on the occurence of common cold (CC) in elderly during a 12-week consumption period.
The purpose of this study is to assess the accuracy and ease-of-use of a simplified FilmArray Respiratory Panel test (FilmArray RP EZ) when performed according to the manufacturer's instructions by personnel in laboratories holding Clinical Laboratory Improvement Amendments (CLIA) waivers (or equivalent) on nasopharyngeal swab samples obtained from volunteers with signs and/or symptoms of a respiratory infection. The study data will be used to support an application to the FDA for CLIA-waived categorization of FilmArray RP EZ. It is hypothesized that the results of the FilmArray RP EZ test performed in a laboratory with CLIA waiver with be 95% accurate when compared to FilmArray RP testing performed in a lab with a moderate or high complexity CLIA certification.
The hypothesis was to establish whether the use of PrevinC administered nasally 2-3 times a day will prevent upper respiratory infections in otherwise healthy adults working in child day care centers.
Poor Ecuadorian older people suffer from chronic dietary deficiencies of zinc, iron, copper, vitamins C, B6, B12, D, and folic acid. The investigators have previously shown that these deficiencies are associated with impaired immune function and increased incidence of respiratory infections (RI). The hypothesis is that correction of these specific nutrient deficiencies will improve immune response and thereby enhance resistance to respiratory infections. To test this hypothesis this study will evaluate the effect of supplementation with specific vitamins and minerals found to be deficient in poor elderly Ecuadorians on markers of immune function and the incidence of RI. A randomized, double-blind, placebo-controlled trial in 320 older people (≥65 y)will be carried out in Quito, Ecuador. Participants will receive multivitamin and mineral supplements or placebo tablets daily for 12 months. Nutrients will be provided at US Recommended Daily Allowance (RDA) levels, except for vitamin C and zinc doses, which will be 5 times and 1.25 times higher than the RDA, respectively. Incidence of respiratory infections (the primary outcome) will be assessed weekly by field nurses and physicians from the study team. Secondary outcomes include delayed-type hypersensitivity (DTH) skin test, cathelicidin production by mucosa respiratory cells, and serum C-reactive protein (CRP) as measures of immune function. Blood micronutrient levels and haemoglobin status will be collected as measures of adherence to the trial regimen. Incidence rate of RI and rate ratio (RR) will be calculated to quantify the effect of the intervention on the incidence of respiratory infection. This will be the first trial of its kind conducted specifically in a population of older people known to have poor micronutrient status. The findings of the study may be important for similar populations in other low- and middle-income countries.
To investigate the effect of milk-based formulas on infections and immune functions in healthy children.
The aim of the study was to assess the effectiveness of a hand-washing programme using hand sanitizer in the prevention of school absenteeism due to upper respiratory infections. Students in intervention classrooms used hand sanitizers at schools and a programme educational on hand hygiene. The investigators hypothesize that the use de hand sanitizers in elementary school will reduce absenteeism due to upper respiratory infections.
The purpose of the planned study is to investigate the effect of heat-treated lactobacilli on diarrhea outcome in healthy children 1-4 years old in a randomized, double-blind, placebo-controlled study.
This is an open label, in-use study to assess the warming sensation, acceptability and local tolerability of paracetamol 500 mg + pseudoephedrine 30 mg syrup, given as a single dose in subjects suffering from symptoms of an upper respiratory tract infection. The purpose is to evaluate the acceptability concerning a warming sensation effect and its potential benefit in the target population. The primary objective is to assess the warming sensation caused by the excipient IFF flavor 316 282, in a syrup containing paracetamol 500 mg + pseudoephedrine 30 mg per 30 ml syrup. The syrup contains (0.15% w/v) warming flavor. The Secondary Objectives are to assess subject acceptability of the syrup and the safety and tolerability of the syrup. The study will be run in fifty-six (56) subjects suffering from symptoms of an upper respiratory tract infection (URTI) for 7 days or less, e.g. nasal congestion associated with colds and flu symptoms such as pain, headache and/or fever. Subjects must have one or more symptoms per category: 1. mild to moderate body pain, headache, fever or sore throat 2. nasal congestion (blocked nose) with or without rhinorrhea (runny nose) or sneezing Adolescents will be included in the study population
