Active clinical trials for "Infections"

The objective of this study is to prevent reactivation of herpes zoster during the first year after transplant.

The study hypothesis is that the addition of Aurograb to standard vancomycin therapy will improve outcome in MRSA infection.

The PRIMAKid trial is a general practice based double-blind randomized placebo-controlled trial on the effectiveness and costs of combined influenza and pneumococcal vaccination in pre-school children with recurrent respiratory tract infections. A target number of 660 children aged 18-72 months with a history of two or more general practitioner attended episodes of RTI, are included. Exclusion criteria are diseases accompanied by a high risk of recurrent RTI and conditions chronically treated with corticosteroids. Over a period of 7 to 22 months follow-up, the number of febrile RTI-episodes as primary outcome is assessed, and as secondary outcomes the severity and length of febrile RTI-episodes, medical visits / interventions, health-related quality of life and productivity loss of parents.

the aim of the current study is to compare the effect of conventional facial PPE as 1)goggles + surgical masks, and 2)face shields + surgical masks versus 3)half-face and 4)full-face reusable respirators; on preoperative child's fear in the dental office.

The COSI BAIR trial will involve approximately 60 children, aged 5 to 8 years old, comprising a subset of participants from the Melbourne Infant Study BCG for Allergy and Infection Reduction (MIS BAIR) randomised controlled trial. The overall aim of this trial is to investigate the specific and heterologous effects of COVID-19 vaccination on immunity in children. COSI BAIR will aim to recruit its participants from the MIS BAIR Bacillus Calmette-Guérin (BCG)-naïve group. These children will be followed up until 28 days after their final Coronavirus Disease 2019 (COVID-19) vaccination. Venous blood samples will be collected at two study visits, at Murdoch Children's Research Institute (MCRI): Day 0 - baseline (day of COVID-19 vaccination #1), and Day 84 (28 days after COVID-19 vaccination #2).

This primary goal of this study is to assess whether patient whose parents watch a standardized digital video using the integrated digital approach during a routine office visit are more likely to accept a dose of HPV vaccine (1st, 2nd, or 3rd dose) compared to those not completing the program. The study team anticipates eligible patients in the intervention clinics to have higher rates of HPV vaccine acceptance (1st, 2nd, or 3rd doses) than patients in the usual care comparison clinics. Additionally, the study team is interested in determining the impact of the integrated system on clinical workflow by measuring the number of minutes of each patient office visit when using the system compared to the number of minutes of each visit in offices where the system is not used. Although this is a descriptive/exploratory aim, our expectation is that the THEO system will have minimal impact on patient flow.

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.

In this study we are trying to understand whether previous infection with a particular virus, namely cytomegalovirus (CMV), influences the ability of the immune system to respond to new infections or vaccinations with age.

Fluoroquinolones (FQ) are among pivotal antibiotic treatments in difficult-to-treat infections. Their efficacy has been shown to be linked to the ratio area under the curve (AUC) of their plasma concentrations over the minimum inhibitory concentration (MIC) of the bacteria treated. Eventually, Forrest et al., reported in gram-negative infections that an AUC/MIC above 125 conducted to a 80 to 90% clinical success whereas success decrease to 30 to 40% in patients with an AUC/MIC below this threshold. These results have been reproduced recently by Zelenitsky et al. in intensive care unit (ICU) patients with threshold similar to the one obtained by Forrest et al. Lastly, elevated concentrations of FQ should be related with the onset of adverse events. Thus, therapeutic drug monitoring (TDM) of FQ appears of potential interest, particularly in case of severe infections (intensive care unit (ICU) patients) or complicated and cost-related infections (osteoarticular infected (OAI) patients), with an increasing level of evidence of its use. However, FQ TDM requires access to the full AUC of the drug with the need of many samples drawn to patients. This appears to be irreconcilable with clinical practice but can be achieved using population pharmacokinetic (PkPop) modelling. PkPop allows estimating pharmacokinetic parameters of the drug by introducing covariates (demographic, biological, clinical…) and modelling inter-individual pharmacokinetic variability. The model created allows then accessing to individual parameters of patients and thus, estimating concentrations and AUC of the FQ. This approach may also be used in clinical practice to determine a limited sampling strategy allowing an adequate estimation of AUC with a minimum of samples.

The purpose of this study is to assess the serologic and cell-mediated immune response to licensed live attenuated influenza vaccine (LAIV) and inactivated influenza vaccine (IIV) in children 5-17 years old. The effects of prior infection and or prior season vaccination will be examined. Children will be followed during the influenza season to identify laboratory-confirmed influenza (i.e. vaccine failure).
