Filter by:The primary objective of this research is to exhaustively document the course and outcomes of hospitalization, labor, delivery, and early postpartum course of up to 15,000 mother-newborn pairs in settings where the occurrence of adverse outcomes is high. The Investigators will gather detailed laboratory, physiologic, and clinical information, and precisely characterize major adverse diagnoses and outcomes. The resulting high-quality, granular, and generalizable data will be used to develop new algorithms to signal actionable intrapartum diagnoses and prospectively stratify women according to their risk for adverse maternal and neonatal outcomes.
Bronchiolitis obliterans (BO) is the well-known manifestation of the chronic pulmonary graft-versus-host disease(GVHD) after allogeneic hematopoietic stem cell transplantation (HSCT). The pathophysiology of BO is, however, poorly known. The available data strongly support the role of respiratory viruses, in particular paramyxoviruses (parainfluenzae virus (PIV), respiratory syncytial virus, metapneumovirus). It is likely that the alloimmune response triggered by the respiratory virus is inadequate and leads to the peribronchiolar fibrotic process. The objective is to analyze the kinetics of profiles of the blood and respiratory host responses resulting from a high or low parainfluenza respiratory infection, in order to evaluate if the occurrence of a BO is associated with a specific signature We will evaluate the predictive signature of a BO after a parainfluenza virus infection by characterizing the differences between the patients evolving and those not evolving to a BO at 2 months after the infection.
This study will analyze gene expression and other laboratory data from biological samples collected from participants with suspected respiratory, urinary, intra-abdominal, and/or skin & soft tissue infections; or suspected sepsis of any cause.
Infections with Streptococcus pneumoniae often cause serious health problems, especially for infants and the elderly.Failure to cover all polysaccharide types is an even greater problem with adults than with children. The aim of the study is to preliminary evaluate the safety and immunogenicity of PBPV vaccine compared to placebo,in order to provide a basis for subsequent clinical trial design.
This phase 2b study will evaluate safety, tolerability, and immunogenicity of an RSV vaccine when given together with Tdap in approximately 710 healthy nonpregnant women 18 through 49 years of age. This study will evaluate non-inferiority of RSV vaccine when given with Tdap and vice-versa.
To evaluate the safety and efficacy of treatment of children with acute bacterial infection disease with Ceftriaxone Sodium and Sulbactam Sodium for Injection in the condition of widely used, and provide the basis of adjusting the dosage regimen for children in particular.
This Phase 2b study will evaluate the safety, tolerability, and immunogenicity of an RSV vaccine in pregnant participants who receive either one of 2 dose levels of the vaccine, formulated with or without aluminum hydroxide, or placebo, and investigate safety and characteristics of antibodies in their infants.
comparing the exercise induced immune response after two weeks on a low carbohydrate (ketogenic) diet with the response after two weeks on a high carbohydrate diet.
This study was performed in children with upper respiratory tract infections (acute ear infection, infection of the tonsils or throat, or bacterial inflammation of the bronchi) who needed treatment with an antibiotic (clarithromycin). The study investigated a new technology which delivers the antibiotic in a straw (dose sipping technology, DST) in comparison to a marketed syrup.
Clinical pneumonia is a leading cause of pediatric hospitalization. The etiology is generally bacterial or viral. Prompt and optimal treatment of pneumonia is critical to reduce mortality. However, adequate pneumonia management is hampered by: a) the lack of a diagnostic tool that can be used at point-of-care (POC) and promptly and accurately allow the diagnosis of bacterial disease and b) lack of a prognostic POC test to help triage children in need of intensive assistance. Antibiotic therapy is frequently overprescribed as a result of suspected bacterial infections resulting in development of antibiotic resistance. Conversely, in malaria-endemic areas, antibiotics may also be "underprescribed" and children with bacterial pneumonia sent home without antibiotic therapy, when the clinical pneumonia is mistakenly attributed to a co-existing malaria infection. The investigators previously identified combinations of protein with 96% sensitivity and 86% specificity for detecting bacterial disease in Mozambican children with clinical pneumonia. The investigators' prior work showed that it is possible to identify biosignatures for diagnosis and prognosis using few proteins. Recently, other authors also identified different accurate biosignatures (e.g., IP-10, TRAIL and CRP). In this study, the investigators propose to validate and improve upon previous biosignatures by testing prior combinations and seeking novel combinations of markers in 900 pediatric inpatients aged 2 months to 5 years with clinical pneumonia in The Gambia. The investigators will also use alternative case criteria and seek diagnostic and prognostic combination of markers. This study will be conducted in Basse, rural Gambia, in two hospitals associated with the Medical Research Council Unity The Gambia (MRCG). Approximately 900 pediatric patients with clinical pneumonia aged 2 months to 5 years of age will be enrolled. Patients will undergo standard of care test and will have blood proteins measured through Luminex®-based immunoassays. Results of this study may ultimately support future development of an accurate point-of-care test for bacterial disease to guide clinicians in choices of treatment and to assist in the prioritization of intensive care in resource-limited settings.
