RESUMO
AIM: Due to the stress that is classically associated with the premature birth of a child, these parents may be prone to sleep disorders. The aim of this study was to compare sleep quality of preterm infants' parents with that of term infants' parents. METHODS: Prospective observational cohort study conducted at the University Hospital of Brest between January 2019 and January 2021. The primary outcome criterion was the score obtained by the parents on the Pittsburg Sleep Quality Index (PSQI) 6 months after their child's birth. Each parent was recruited in the days following their child's birth and completed the PSQI online. RESULTS: Overall, 316 parents were included. The median gestational age at birth was 34.3 (31.6-35.5) weeks in the preterm infant group and 39.7 (38.6-40.7) weeks in the term infant group. Of the 948 expected questionnaires, 771 were completed and collected. On average, 59% of the parents obtained a PSQI global score >5. Six months after birth, no differences were reported between parents of preterm and full-term infants. CONCLUSION: This study did not reveal any difference between sleep quality of preterm infants' parents and term infants' parents.

Habituation has been a topic of interest since the early 20th century. We summarise the characteristics of habituation, the proposed habituation mechanisms, the associated cortical responses and the link between habituation and cognitive development. Behavioural and neuroimaging studies have highlighted the early sensory abilities of foetuses and newborn infants, with preterm newborn infants exhibiting decreased habituation and dishabituation capabilities that increase their environmental vulnerability. Habituation provides a foundation for the learning and cognition on which higher functions are constructed. It has been suggested that it is efficient for predicting cognitive developmental outcomes in term and preterm newborn infants.

Pharmacokinetic modeling has often been applied to evaluate vancomycin pharmacokinetics in neonates. However, clinical application of the model-based personalized vancomycin therapy is still limited. The objective of the present study was to evaluate the clinical utility and safety of a model-based patient-tailored dose of vancomycin in neonates. A model-based vancomycin dosing calculator, developed from a population pharmacokinetic study, has been integrated into the routine clinical care in 3 neonatal intensive care units (Robert Debré, Cochin Port Royal, and Clocheville hospitals) between 2012 and 2014. The target attainment rate, defined as the percentage of patients with a first therapeutic drug monitoring serum vancomycin concentration achieving the target window of 15 to 25 mg/liter, was selected as an endpoint for evaluating the clinical utility. The safety evaluation was focused on nephrotoxicity. The clinical application of the model-based patient-tailored dose of vancomycin has been demonstrated in 190 neonates. The mean (standard deviation) gestational and postnatal ages of the study population were 31.1 (4.9) weeks and 16.7 (21.7) days, respectively. The target attainment rate increased from 41% to 72% without any case of vancomycin-related nephrotoxicity. This proof-of-concept study provides evidence for integrating model-based antimicrobial therapy in neonatal routine care.

AIM: Polysomnography is the gold standard for studying sleep, but it is complex to use, and this can be problematic in clinically unstable preterm infants. We evaluated the reliability of actigraphy and polysomnography in detecting sleep-wake patterns in newborn infants. METHODS: A prospective, monocentric study was conducted that measured the sleep patterns of 48 infants: 24 late preterm neonates born at 34-36 weeks of gestational age and 24 term neonates. We used both polysomnography and the Actiwatch Mini during a three-hour period and then compared the results from the two methods. RESULTS: The baseline measurements for the preterm and terms groups were as follows: gestational age (34.5 weeks and 39.2 weeks), birthweight (2368 g and 3393 g) and age (6.4 days and 0.72 days). With the Actiwatch Mini, sensitivity for the late preterm and full-term infants was 78% and 87% for the leg actigraph and 78% and 93% for the arm actigraph. For specificity, the respective figures were 42% and 31% for the leg and 34% and 20% for the arm. CONCLUSION: Actigraphy using the Actiwatch Mini was not a reliable method for measuring sleep patterns in healthy late preterm and term neonates a few days after birth.

In-line filtration is increasingly used in critically-ill infants but its benefits, by preventing micro-particle infusion in very preterm neonates, remain to be demonstrated. We conducted a randomized controlled trial among very preterm infants allocated to receive either in-line filtration of all the intra-venous lines or standard care without filters. The primary outcome was differences greater than 20% in the median changes in pro-inflammatory cytokine serum concentrations measured at day 3 and day 8 (+/-1) using a Luminex multianalytic profiling technique. Major neonatal complications were analyzed as secondary predefined outcomes. We randomized 146 infants, assigned to filter (n = 73) or control (n = 73) group. Difference over 20% in pro-inflammatory cytokine concentration between day 3 and day 8 was not found statistically different between the two groups, both in intent-to-treat (with imputation) and per protocol (without imputation) analyses. The incidences of most of neonatal complications were found to be similar. Hence, this trial did not evidence a beneficial effect of in-line filtration in very preterm infants on the inflammatory response syndrome and neonatal morbidities. These data should be interpreted according to local standards in infusion preparation and central line management.

BACKGROUND: Improving pain and stress assessments in neonates remains important in preventing the short- and long-term consequences. We aimed to identify the relationships between different pain assessment parameters by simultaneously measuring changes in cortical, autonomic, hormonal, physiological, and behavioral evoked responses to venepuncture in healthy, full-term neonates. METHODS: This observational, prospective study (ancillary to the ACTISUCROSE trial) included 113 healthy, 3-day old, full-term neonates who underwent venepuncture for systematic neonatal screening, from July to October 2013, in a tertiary-level maternity ward of a university hospital. During venepuncture, we simultaneously measured the cortical single-channel near-infrared spectroscopy (NIRS) signals, foot skin conductance, salivary cortisol, physiological responses, and behavioral (Neonatal Facial Coding System [NFCS]) evoked responses. RESULTS: Regarding the NIRS analysis, the highest correlation was between the NFCS at venepuncture and the change in NIRS integrated values of total hemoglobin (r=0.41, P<0.001) or oxygenated hemoglobin (r=0.27, P<0.001). The NFCS at venepuncture was moderately positively correlated with changes in salivary cortisol (r=0.42, P<0.001) and skin conductance (r=0.29, P<0.001). Salivary cortisol and skin conductance changes were not correlated; the latter parameters were not correlated with heart rate, respiratory rate, or SpO2. CONCLUSION: During venepuncture, NFCS was mildly or moderately correlated with salivary cortisol, skin conductance, and cortical NIRS changes.
RESUMO
OBJECTIVE: Sucrose administration and breastfeeding decrease behavioral expressions of pain in neonates. However, recent studies indicated that there is a persistent cortical response with sucrose. This study compared the efficacy of sucrose administration versus breastfeeding to decrease cortical responses to pain during venepuncture. PATIENTS AND METHODS: A randomized, prospective, controlled trial was conducted in a tertiary level maternity ward. Healthy, 3-day-old term neonates, undergoing venepuncture for neonatal screening, were randomly assigned to receive sucrose solution or be breastfed before venepuncture. Variations in the total hemoglobin concentration [HbT] in the contralateral somatosensory cortex were assessed with near infrared spectroscopy. The Neonatal Facial Coding System (NFCS) was used to assess reactions. RESULTS: There were 114 term neonates included, with 102 included for the primary outcome (breastfed group: 48; sucrose group: 54). Similar maximum increases in [HbT] were observed in both groups (mean±SD: sucrose group: 31.2±58.1 µmol/L; breastfed group: 38.9±61.4 µmol/L; P=0.70). Breastfed neonates presented more behavioral expressions that indicated pain compared with sucrose-administered neonates (46.8% vs. 26.8% of NFCS ≥1, P=0.04). The maximum increase in [HbT] was persistent, although newborn infants who did not express behavioral signs of pain had lower concentrations than neonates who did (mean±SD: 21.2±29.1 vs. 60.0±89.8 µmol/L, P<0.01). DISCUSSION: There was no difference in the cortical responses to pain during venepuncture in newborn infants who were administered sucrose versus those who were breastfed.

We describe the first case of sepsis due to a yet unnamed species of Dyella genus associated to gastrointestinal perforation in a premature newborn. The rarity of such environmental bacteria in human infection, their misidentification with classical methods and their antibiotic resistance represent real challenges for both microbiologists and clinicians.
