Dynamics of the digestive acquisition of bacterial carriage and integron presence by French preterm newborns according to maternal colonization: The DAIR3N multicentric study.

Objectives: The study aimed to describe the dynamics and risk factors of Gram-negative bacteria (GNB) acquisition in preterm infants.

Methods: This prospective multicenter French study included mothers hospitalized for preterm delivery and their newborns, followed until hospital discharge. Maternal feces and vaginal fluids at delivery, and neonatal feces from birth to discharge were tested for cultivable GNB, potential acquired resistance, and integrons.

Staphylococcus capitis isolated from bloodstream infections: a nationwide 3-month survey in 38 neonatal intensive care units.

To increase the knowledge about S. capitis in the neonatal setting, we conducted a nationwide 3-month survey in 38 neonatal intensive care units (NICUs) covering 56.6% of French NICU beds.

Succinate-CoA ligase deficiency due to mutations in SUCLA2 and SUCLG1: phenotype and genotype correlations in 71 patients.

Background: The encephalomyopathic mtDNA depletion syndrome with methylmalonic aciduria is associated with deficiency of succinate-CoA ligase, caused by mutations in SUCLA2 or SUCLG1. We report here 25 new patients with succinate-CoA ligase deficiency, and review the clinical and molecular findings in these and 46 previously reported patients.

Patients And Results: Of the 71 patients, 50 had SUCLA2 mutations and 21 had SUCLG1 mutations.

Sonography-guided positioning of intravenous long lines in neonates.

Objective: In neonates, proper positioning of the tip of intravenous long lines (LL) is essential in order to prevent potential life-threatening complications. The gold standard for the evaluation of LL position in neonates is the chest X-ray with or without contrast. We performed a prospective study to assess the use of transthoracic ultrasonography (US) for the positioning of LL in neonates and to compare it to plain radiography.
