Active clinical trials for "Respiratory Tract Infections"

Our hypothesis - that 21 days of mountain spa rehabilitation with ubiquinol supplementation could to accelerate regeneration of patients with post-COVID-19 syndrome, based on the improving platelet mitochondrial bioenergetic, decreasing of oxidative stress and improving of antioxidants protections of patients with post-COVID-19 syndrome.

This trial is taking place in Los Angeles, CA among patients from primary care practices within the UCLA Health System. The study design is a parallel 2-arm trial. The parallel arms are 1) a reminder letter for the second dose of influenza vaccine (reminder messages sent via the patient portal) with a direct appointment scheduling link included in the reminder and 2) a reminder letter for the second dose of influenza vaccine, but no direct appointment scheduling link included.

Findings from an ongoing improvement project to improve antibiotic prescribing for children and adolescents for three acute respiratory tract infections (ARTIs: upper respiratory tract infection, acute bacterial sinusitis, and acute otitis media) among pediatric and family medicine clinics revealed performance gaps between the two primary care specialties. An improvement project was then set up to address the lower performance by family medicine clinics. Literature review revealed that, in general, quality improvement feedback was more effective if provided to individual clinicians rather than to a group of clinicians, but very limited data existed for antibiotic prescribing practices actually comparing individual clinician feedback to group (clinic-level) feedback. The hypothesis is that individual clinician data feedback is superior to group (clinic-level) feedback in improving antibiotic prescribing for ARTIs in children and adolescents by family medicine clinicians. The aim is to determine if there are significant differences for antibiotic prescribing for ARTIs and for broad spectrum antibiotic prescribing percentage between an intervention group and a comparator group of family medicine clinics after the intervention starting November 2015 and ending December 2018. A cluster randomized trial was designed for 39 family medicine clinics. The intervention group received clinician-level and clinic-level data feedback monthly, and the comparator group received clinic-level only feedback monthly.

This is a two-arm, randomized, open label, monocenter, controlled study to evaluate the safety and efficacy of Viusid plus Asbrip in patients with mild and moderate symptoms of respiratory illness caused by Coronavirus 2019 infection.

The purpose of this study is to evaluate the positivity rate of respiratory syncytial virus (RSV), influenza virus and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in high-risk participants presenting with acute respiratory infections (ARIs) in outpatient settings during the influenza/RSV season and to evaluate the association between lower respiratory tract disease (LRTD) and ARI-related hospitalization in participants positive for RSV.

The study will evaluate the change in gastrointestinal (GI) flora following probiotic supplementation, and expected to lead to an increase in the intestinal epithelial integrity and to improvement in its health. Concurrently with the reduction in the amount of toxins in the GI tract following an intensive exercise, a lower incidence of symptoms of discomfort will improve the quality of the training sessions which will be exhibited by an improvement in endurance capacity and in physiological responses to rigorous exercise. Half of the participants will receive probiotic supplement while the other half will receive a placebo.

Critically ill patients are often ventilated in dedicated critical care units to provide respiratory support. Despite best practice patients can often develop a condition called adult respiratory distress syndrome (ARDS), which is characterised by deterioration in their respiratory function, and changes on chest x-ray. The correct management for ARDS is identifying the underlying condition causing the deterioration and identifying appropriate targeted therapy. One such cause is pneumonia, caused by a bacterial infection in the lungs of a ventilated patient. The patients may have been ventilated due to pneumonia but they may also develop pneumonia whilst ventilated. Ventilator associated pneumonia (VAP) has significant mortality. Despite all the clinical and laboratory data at the investigators' disposal there remains great difficulty in the accurate diagnosis of pneumonia and therefore treatment is often given empirically. Therefore, there is an urgent clinical need for accurate methods to diagnose the presence of bacteria deep in the lung in ventilated critically ill patients. As such, the investigating team have developed and synthesised an imaging agent called BAC TWO. BAC TWO will be instilled directly into the lungs of 12 patients to assess whether it can label gram-negative bacteria in the human lung.

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.

Use of information campaigns and educational interventions directed to citizens and supported by physicians, aimed at promoting the appropriate use of medicines, have been evaluated by several studies with conflicting results. These interventions are potentially relevant, favouring the reduction of unnecessary use of medicines and related risks. Several studies have specifically evaluated the promotion of the appropriate use of antibiotics in adults and children, with variable results. A controlled study has been proposed to evaluate the feasibility and effectiveness of a multifaceted intervention aimed at reducing antibiotic prescription by increasing awareness on risks of their unnecessary use. Information has been provided to citizens through several media (posters, local TV, radio and newspapers, video terminals, websites of Local Health Authorities). Brochures with information on expected benefits and risks of antibiotics has also been available, either with direct access in waiting rooms and pharmacies or handed out and mediated by doctors. Physicians and pharmacists received specific data on local antibiotic resistance. A small group of representative doctors have also actively participated in defining the campaign key messages. A sample of general practitioners and paediatricians have been trained in patient counselling strategies. The information campaign has been implemented in two Provinces of Emilia-Romagna during the fall-winter season (November 2011-February 2012). Change in the overall prescribing rate of antibiotics (expressed as DDD per 1000 inhabitants/day) in the intervention area will be compared versus other areas in the same Region. Knowledge and attitudes of the general population will be evaluated through a phone and internet survey on a representative sample. This study could observe a reduction lower than 5% in the prescribing rate of antibiotics.

For most individuals, the lung has a remarkable ability to deal with exposure to a variety of inhaled bacteria. Some individuals, however, do have recurrent bacterial infections, usually in the form of acute or chronic bronchitis and, in some instances, pneumonia. The reasons for this variability in bacterial infections between otherwise healthy subjects, between types of lung disease, and within the same type of lung disease are poorly understood. Variability in susceptibility to bacterial infections is partially explained by differences in exposure to infectious agents, genetic susceptibility and innate (or early) immune responses. It is of interest that the incidence and severity of bacterial infections is greatest during the winter months. Other than viral infections, there are few variables that change with season. Vitamin D is one known immune modulator with a seasonal periodicity. The hypothesis of this study is that levels of vitamin D are an important determinant of the innate defense of the lung against inhaled bacteria. The investigators further postulate that vitamin D has effects on the innate immune function of both alveolar macrophages and lung epithelial cells.
