Mycobacterium chimaera, belonging to the Mycobacterium avium complex, is an opportunistic environmental mycobacterium which has been isolated from medical device water samples such as Heater Cooler Units (HCU). Laboratories currently use culture-based diagnostic methods to detect M. chimaera, but these take a long time to obtain results.

- This study investigates the effectiveness of two surfactant administration methods—INtubate-RECruit-SURfactant-Extubate (IN-REC-SUR-E) and less invasive surfactant administration (LISA)—on improving BPD-free survival in preterm infants with respiratory distress syndrome (RDS).
- A total of 382 preterm infants, born at 24-27 weeks' gestation and not intubated at birth, will be randomly assigned to either method within the first 24 hours of life. The primary outcome being measured is a combination of death or bronchopulmonary dysplasia (BPD) at 36 weeks' postmenstrual age.
Objectives: Seizures (SZ) are one of the main complications occurring in infants undergoing therapeutic hypothermia (TH) due to perinatal asphyxia (PA) and hypoxic ischemic encephalopathy (HIE). Phenobarbital (PB) is the first-line therapeutic strategy, although data on its potential side-effects need elucidation. We investigated whether: i) PB administration in PA-HIE TH-treated infants affects S100B urine levels, and ii) S100B could be a reliable early predictor of SZ.

Therefore, it would be informative to determine the spatial distribution of grey matter (GM) CBF in PT and full-term (FT) newborns at term-equivalent age (TEA) and to assess the relationship between the features of the CBF pattern and both prematurity and prematurity-related brain lesions. In this prospective study, we obtained measures of CBF in 66 PT (51 without and 15 with prematurity-related brain lesions) and 38 FT newborns through pseudo-continuous arterial spin labeling (pCASL) MRI acquired at TEA.

This study set out to investigate the presence of SARS-CoV-2 on surfaces near subjects receiving NIV in the ICU under controlled conditions (ie, use of dual-limb circuits, filters, adequate room ventilation).
Methods: This was a single-center, prospective, observational study in the ICU of a tertiary teaching hospital.
