Study protocol for controlled human infection for penicillin G against Streptococcus pyogenes: a double-blinded, placebo-controlled, randomised trial to determine the minimum concentration required to prevent experimental pharyngitis (the CHIPS trial)Regular intramuscular benzathine penicillin G injections have been the cornerstone of rheumatic heart disease (RHD) secondary prophylaxis since the 1950s. As the pharmacological correlate of protection remains unknown, it is difficult to recommend changes to this established regimen. Determining the minimum effective penicillin exposure required to prevent Streptococcus pyogenes infection will accelerate development of new long-acting penicillins for RHD prevention as well as inform opportunities to improve existing regimens. The CHIPS trial will address this knowledge gap by directly testing protection afforded by different steady state plasma concentrations of penicillin in an established model of experimental human S. pyogenes pharyngitis.

Diet at birth is critical for healthy growth, independent of effects on the gut microbiotaColostrum is the first milk for a newborn. Its high content in microbiota shaping compounds and its intake at the time of gut microbiota seeding suggests colostrum may be critical in the establishment of a healthy microbiota. There is also accumulating evidence on the importance of the gut microbiota for healthy growth.

Safety and Tolerability of V114 Pneumococcal Vaccine in Infants: A Phase 3 StudyDisease caused by Streptococcus pneumoniae is associated with considerable morbidity and mortality in children. Pneumococcal conjugate vaccines are well tolerated and effective at reducing pneumococcal disease caused by vaccine serotypes. VAXNEUVANCE (V114) is a 15-valent PCV containing 13 serotypes in Prevnar 13, plus serotypes 22F and 33F. This large phase 3 study evaluated safety and tolerability of V114 in infants.

Child maltreatment data: A summary of progress, prospects and challengesIn 1996, the ISPCAN Working Group on Child Maltreatment Data (ISPCAN-WGCMD) was established to provide an international forum in which individuals, who deal with child maltreatment data in their respective professional roles, can share concerns and solutions.
