Abstract
Respiratory Syncytial Virus (RSV) bronchiolitis is the leading cause of hospitalization in infants. The role of RSV load in disease severity is still debated. We present the interim results of a prospective monocentric study enrolling previously healthy infants hospitalized for RSV bronchiolitis, collecting nasopharyngeal aspirates every 48 h from admission to discharge, and evaluating RSV load dynamics in relation to clinical outcome measures of bronchiolitis severity, including: need, type and duration of oxygen therapy, length of hospitalization, and the bronchiolitis clinical score calculated at admission. The results showed that the highest viral replication occurs within the first 48 hours after admission, with a significant decrease at subsequent time points (p < 0.0001). Moreover, higher RSV-RNA values were associated with the need for oxygen therapy (p = 0.03), particularly high-flow nasal cannula type (p = 0.04), and longer duration of respiratory support (p = 0.04). Finally, higher RSV load values were correlated with lower white blood cells, especially lymphocyte counts and C-reactive protein levels (p = 0.03, p = 0.04, and p = 0.01, respectively), as well as with patients of a younger age (p = 0.02). These data suggest that RSV may actively contribute to the clinical severity of bronchiolitis, together with other potential non-viral factors.

Abstract
OBJECTIVE To determine what is known about the sleep experiences of mothers of hospitalized preterm infants. DATA SOURCES A literature search of PubMed and CINAHL was performed in February 2018. Additional articles were identified from reference lists. STUDY SELECTION Whittemore's integrative review methodology was used to synthesize existing literature; 17 articles met eligibility criteria. DATA EXTRACTION Data were reported in tabular format, including subjects, purpose, setting, interventions, sleep measurements, psychometric instruments, analyses, and results. DATA SYNTHESIS Overall, sleep is disrupted and of poor quality, and many mothers report insomnia with less total sleep time. Potential beneficial interventions include bright light therapy, relaxation guided imagery, and progressive muscle relaxation. CONCLUSION Although some interventions show promise, there are significant limitations. Future research should consider maternal/infant separation and milk expression.
