Voluntary alcohol binge-drinking in adolescent C57Bl6 mice induces delayed appearance of behavioural defects in both males and females.

Adolescence is a developmental period characterized by significant changes in brain architecture and behaviour. The immaturity of the adolescent brain is associated with heightened vulnerability to exogenous agents, including alcohol. Alcohol is the most consumed drug among teenagers, and binge-drinking during adolescence is a major public health concern.

Proteostasis is essential during cochlear development for neuron survival and hair cell polarity.

Protein homeostasis is essential to cell function, and a compromised ability to reduce the load of misfolded and aggregated proteins is linked to numerous age-related diseases, including hearing loss. Here, we show that altered proteostasis consequent to Elongator complex deficiency also impacts the proper development of the cochlea and results in deafness. In the absence of the catalytic subunit Elp3, differentiating spiral ganglion neurons display large aggresome-like structures and undergo apoptosis before birth.

Long-term Association of 13-Valent Pneumococcal Conjugate Vaccine Implementation With Rates of Community-Acquired Pneumonia in Children.

Importance: In several countries, 5 years after 13-valent pneumococcal conjugate vaccine (PCV13) implementation, serotype replacement has been reported for invasive pneumococcal disease, which raises concerns about the long-term outcome of PCV13 implementation. The long-term effect of vaccination on community-acquired pneumonia (CAP) remains unknown.

Objective: To assess the long-term outcome of PCV13 implementation on CAP in children.

Febrile urinary-tract infection due to extended-spectrum beta-lactamase-producing Enterobacteriaceae in children: A French prospective multicenter study.

Objectives: To assess the management of febrile urinary-tract infection (FUTIs) due to extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) in children, the Pediatric Infectious Diseases Group of the French Pediatric Society set up an active surveillance network in pediatric centers across France in 2014.

Materials And Methods: We prospectively analysed data from 2014 to 2016 for all children < 18 years old who received antibiotic treatment for FUTI due to ESBL-E in 24 pediatric centers. Baseline demographic, clinical features, microbiological data and antimicrobials prescribed were collected.

Bacterial meningitis antibiotic treatment.

The implementation of pneumococal conjugate vaccines (PCVs) 7 then 13 valent (Prevenar13 in 2010-2011 has significantly changed the profile of pneumococcal meningitis. Since 3 years, the National Pediatric Meningitis Network of the Pediatric Infectious Disease Group (GPIP) and the National Reference Centre of Pneumococci have reported no cases of meningitis due to pneumococcus resistant to third-generation cephalosporins (3GC): cefotaxime or ceftriaxone. In the light of these new data, vancomycin should no longer be prescribed at the initial phase of pneumococcal meningitis treatment (confirmed or only suspected) and this antibiotic should only be added when 3GC minimum inhibitory concentration of the strain isolated is greater than 0.
