Filter by:The objective of our study is therefore to study the evolution of the respiratory microbiome of hospitalized newborns, its interaction with viral infections and their impacts on the evolution of newborns.
A single-center, randomized, open, single-dose, two-cycle, two-sequence, cross-over study was conducted to evaluate the effect of food on the pharmacokinetic characteristics of GST-HG171 in combination with Ritonavir.
This trial is taking place in Los Angeles, CA at 21 clinics within the UCLA Health System. The study design is a 3 arm randomized trial. Patients will be randomized into 1) receiving portal based reminder messages with a video from their PCP encouraging them to receive the influenza vaccine, 2) portal-based reminder messages with an infographic with the image of their PCP encouraging them to receive the influenza vaccine, or 3) the control group. Patients randomized to the intervention arms will receive reminders if they are due for influenza vaccine. Despite the Advisory Committee on Immunization Practices (ACIP) recommendation in 2010 that all people above 6 months of age should receive an annual flu vaccine, vaccination rates remain low: at 6m-4.9 yrs. (70%), 5-17.9 yrs. (56%), 18-64.9 yrs. (38%), and >65 yrs. (63%). The investigators will assess the effectiveness of MyChart R/R video messages and infographic messages as compared to the standard of care control (Health system messages).
The goal of this randomized non-pharmacological Intervention study is to evaluate the effects of probiotic supplements (Bifidobacterium breve M-16V, Bifidobacterium lactis HN019, Lactobacillus rhamnosus HN001) on children affected by upper respiratory tract infections. The main questions it aims to answer are: - probiotic formulation can reduce intensity and duration of fever in children affected by upper respiratory tract infections - probiotic formulation can influence the gut microbiota composition in children affected by upper respiratory tract infections Participants will be asked to take probiotic supplements or placebo for 14 days and to collect three fecal samples: before probiotic supplementation (T0), 14 days after probiotic supplementation (T1), and 12 months after the enrollment (T2).
Respiratory syncytial virus (RSV) infection and bacterial co-infection are the most common causes of pneumonia. Currently, there is no vaccine available for RSV prevention, and the use of the antiviral medication ribavirin is not widely recommended for children. Therefore, the primary treatment approach follows the general protocol for pneumonia, and oxygen therapy is recommended for all cases of pneumonia with respiratory failure. However, in children, the treatment of RSV and bacterial pneumonia remains supportive to prevent bacterial co-infection and respiratory failure. Probiotics have emerged as promising and safe options for supporting the treatment of acute respiratory tract infections (ARTIs) and reducing dependence on antibiotics in recent years. In this study, investigators propose that the direct administration of probiotics through a nasal spray can offer rapid and effective symptomatic treatment for children with pneumonia who require oxygen therapy due to RSV and bacterial co-infections. The aim of the study is to evaluate the effectiveness of nasal-spraying probiotics containing spores of two bacterial strains, Bacillus subtilis and Bacillus clausii (LiveSpo Navax), in preventing and supporting the treatment of severe pneumonia in children (who require oxygen therapy) caused by RSV infection and bacterial co-infection. Study population: The sample size was 100, and the study was conducted at the Vietnam National Children's Hospital. Description of Study Intervention: All 100 eligible patients were randomly divided into two groups (n = 50/each): Patients in the Control group received routine treatment and were administered 0.9% NaCl physiological saline 3 times/day, while the patients in the Navax group received LiveSpo Navax 3 times/day in addition to the same standard of care treatment. The standard treatment regimen typically lasts for 5-7 days, but its duration can be extended based on the severity of the patient's respiratory failure. Study duration: 12 months.
This Phase 2, randomized, observer-blind clinical study is evaluating 3 different priming and booster regimens with MF59-adjuvanted H5N8 and/or H5N6 cell culture-derived influenza vaccine (aH5N8c; aH5N6c). Approximately 480 healthy adult subjects are to be randomized into 1 of 3 possible treatment groups, stratified by age group (18-64 years and ≥65 years) and by poultry worker status (yes/no). Each subject will receive a priming influenza vaccine injection on Day 1 and Day 22 and a booster vaccination on Day 202. Subjects will be followed up for approximately 6 months after the booster injection. The primary immunogenicity analysis is based on antibody responses against H5N8 and H5N6 as measured by hemagglutination inhibition (HI) assay on Day 1, Day 22, Day 29, Day 43, Day 202, Day 209 (H5N8 only), and Day 223.
The study hypothesizes that SARS-CoV-2 vaccination poisoning hibernates in human host in Low Density Lipoprotein Cholesterol (LDL-C). The clinical trial is a follow-up from the intervention trial with NCT number NCT05711810. It tests the use of Atorvastatin Calcium Tablets for detoxification and prevention of blood acidification, and the use of the Chinese herb compounded Anti-Viral Granules for the detoxification in the endocrine system.
The goal of this clinical trial is to assess the immunogenicity, efficacy and safety of the Convacell vaccine in healthy adult volunteers aged 18 years and older. The main questions it aims to answer are: - To assess the immunogenicity and safety of single and double dose intramuscular administration of the Convacell vaccine; - To assess the epidemiological effectiveness of the Convacell vaccine in the prevention of SARS-CoV-2 infection and development of severe COVID-19 compared with placebo when single or double intramuscular injection.
This study was conducted to investigate the effects of daily supplementation of Allium Cepa L. Peel Heated Water Extract on Immunity Enhancement
Streptococcus pneumoniae infections often cause serious health problems, especially in infants and the elderly. Failure to cover all polysaccharide types of vaccines is a greater problem for adults than for children. The purpose of this study was to preliminarily evaluate the safety and immunogenicity of a recombinant pneumococcal protein vaccine applied to adults aged 50 years and older to provide a basis for subsequent clinical trial design.
