HSV G207 in Children With Recurrent or Refractory Cerebellar Brain Tumors

This study is a clinical trial to determine the safety of inoculating G207 (an experimental virus therapy) into a recurrent or refractory cerebellar brain tumor. The safety of combining G207 with a single low dose of radiation, designed to enhance virus replication, tumor cell killing, and an anti-tumor immune response, will also be tested.

Genetic Determinants of the Antiviral Immune Response in Oceanian Populations

Oceania's populations, including Melanesians, are paying a heavy price for dengue fever, which has been circulating actively in the region since the Second World War. In New Caledonia (NC), the incidence of dengue fever is higher among municipalities predominantly populated by Melanesians, suggesting that Melanesians may have an increased susceptibility to symptomatic dengue fever. Differences in antiviral immune responses between populations of different geographical origins are partly the result of population-specific immune regulatory variants. In turn, viruses have imposed considerable selective pressure on human populations. Although crucial to understanding their susceptibility to viral infections, the genetic determinants of the antiviral immune response of Oceanians remain to be characterized. In this context, the hypothesis is that the genetic origin of Oceanians, and Melanesians in particular, has shaped their antiviral immune response and contributes to their greater susceptibility to certain viral infections. The aim is to characterize the immune response to pathogens affecting the New Caledonian population, and in particular to dengue virus, of Melanesian and European populations, and to identify its genetic determinants. It will be explored whether saliva can be used as a non-invasive sample to study the seroprevalence of dengue in Oceanian populations.

Effects of Photobiomodulation on the Innate Immune System of Neonates and Infants With Bronchiolitis

The innate immune response of children with acute viral bronchiolitis (AVB) caused by respiratory syncytial virus (RSV) in the acute phase and in the resolution phase, is marked by variations in inflammatory and anti-inflammatory mediators, where in the acute phase there is recruitment and activation of multiple cells of the immune system, with consequent increase in the expression of pro-inflammatory mediators. Evidence indicates that there is a considerable increase in tumor necrosis factor-alpha (TNF) , interleukine 6 (IL6), interleukine 1-beta, interleukine 8 (IL8) interleukine 10 (IL10), exposing to IL6, IL8 and IL-10 positively correlated with AVB severity. There are already reports that the transcutaneous application of photobiomodulation (PBM) reaches the lungs, producing positive responses in respiratory pathologies, both acute and chronic . Thus, PBM caused by the use of low-level laser may be a favorable resource to be used in the area of respiratory physiotherapy, specifically in neonatology and pediatrics, since there are studies in both experimental and human models that prove its action on lung cells, acting to reduce airway edema, reduce neutrophil migration to lung tissue and synthesize pro-inflammatory cytokines TNFalpha, IL6 and IL-10. In addition, it is a portable, practical, quick application, with minimal contraindications and possibly better tolerated by the neonatal and pediatric population.

The DETECT(Digital Engagement & Tracking for Early Control, & Treatment) Study

Develop an app-based nationwide study of individuals who routinely use a smartwatch or other wearable activity tracker to determine if individualized tracking of changes in heart rate, activity and sleep can provide an early indication of influenza-like illnesses (ILI) and possibly other viral infections.
