Abstract
Aim To investigate the ratio of cerebral tissue oxygenation index (cTOI) to peripheral muscle tissue oxygenation index (pTOI) measured by near-infrared spectroscopy (NIRS) in cardio-circulatory stable preterm neonates without signs of inflammation/infection on the first day after birth. Methods Observational study analysing secondary outcome parameters of the 'Avoiding Hypotension in Preterm Neonates (AHIP)' trial (ClinicalTrials.gov identifier: NCT01910467). Preterm neonates, who had cTOI and pTOI measurements during 24 h after birth, were included. In each neonate the mean of the cTOI/pTOI-ratio, cTOI, pTOI and routine monitoring parameters were calculated for each hour and for the 24-h measuring period. Courses of all measured parameters were analysed. Results Eighty-seven stable preterm neonates (33.1 [32.1-34.1] weeks of gestation) were included. The mean value over the 24-h measuring period for the cTOI/pTOI-ratio was 0.96 ± 0.02, for cTOI 70.1 ± 1.4 and for pTOI 73.4 ± 0.9. Routine monitoring parameters were in the normal ranges over 24 h. The courses of the cTOI/pTOI-ratio and cTOI showed significantly lower values from hour 5 to 15 compared to the first hours after birth. Heart rate decreased significantly over time, whereas mean arterial blood pressure increased significantly. pTOI, arterial oxygen saturation and body temperature showed no significant change over time. Conclusion We are the first to report on cTOI/pTOI-ratios for cardio-circulatory stable preterm neonates over a 24-h period after birth, showing significantly lower values from hour 5 to 15 compared to the first hours after birth.

Abstract
Background: Preterm birth is associated with increased stress of parents that might influence the parental-child interaction, thus potentially having influence on the neurobehavioral development of the preterm infants. However, little is known concerning the age dependency of parental stress after preterm birth. Objective: The aim of the present study was to examine the age dependency of stress in mothers and fathers after preterm birth and neonatal intensive care unit (NICU) admission of their infant. Methods: In a prospective observational pilot study 47 mothers and 47 fathers completed the parental stress scale:NICU (PSS:NICU) questionnaire within 72 h after delivery. This questionnaire measures parental stress after preterm birth with three subscales: "Looks and Behave" of the child, "Parental Role Alteration," and "Sights and Sounds." Stress levels of mothers and fathers were compared and correlated to the age of mothers and fathers, respectively. Results: Parental stress experience after preterm birth tended to be higher in mothers compared to fathers. Mothers showed a significant positive correlation of the "Sights and Sounds" scale and age, whereas fathers did not show any significant age dependency of stress. Conclusion: In mothers stress level increases with increasing maternal age after preterm birth and admission of their infant to NICU, whereas fathers did not show any significant age dependency of stress.

Abstract
This article provides a narrative review of lung-protective ventilatory strategies (LPVS) in intubated preterm infants with RDS. A description of strategies is followed by results on short-and long-term respiratory and neurodevelopmental outcomes. Strategies will include patient-triggered or synchronized ventilation, volume targeted ventilation, the technique of intubation, surfactant administration and rapid extubation to NCPAP (INSURE), the open lung concept, strategies of high-frequency ventilation, and permissive hypercapnia. Based on this review single recommendations on optimal LPVS cannot be made. Combinations of several strategies, individually applied, most probably minimize or avoid potential serious respiratory and cerebral complications like bronchopulmonary dysplasia and cerebral palsy.

Abstract
Background Preterm birth is known to be a stressful and anxious situation for parents, which might have long-term impact on the psychological health of mothers and even on the development of their preterm infants. Objective The Parental Stressor Scale: Neonatal Intensive Care Unit (PSS:NICU) was developed to assess parental stress after preterm birth through three subscales [1]. The aim of the present study was to examine the psychometric properties and the dimensionality of the German version of the PSS:NICU to develop a reliable German version of the PSS:NICU. Methods For the development (exploratory factor analysis) 100 parents of preterm infants answered the questionnaire. Results The Sights and Sounds subscale was removed from the German version of the PSS:NICU due to low number of items. A PSS NICU_German/2-scales was developed consisting of 2 subscales: Infant Behavior and Appearance (7 Items, Cronbach's α=0,82) and Parental Role Alteration (6 Items, Cronbach's α=0,87). Conclusions The PSS:NICU_German/2-scales is a reliable and economic scale for the assessment of parental stress after preterm birth.

Abstract
BACKGROUND Routine oropharyngeal suctioning in term vigorous neonates immediately after birth is a questionable practice. Current recommendations favor suctioning only in the presence of considerable obstruction due to secretions, blood or other matter. We aimed to analyze the influence of oropharyngeal suctioning on cerebral and peripheral muscle oxygenation in term neonates during transition immediately after birth. METHODS We included term neonates after elective cesarean section for this prospective observational study. Oropharyngeal suctioning was performed based on the clinicians' judgment of threatening airway obstruction. From a total of 138 enrolled neonates, 36 were suctioned and then compared to 36 controls matched for gestational age. Heart rate (HR) and pre/postductal arterial oxygen saturation (SpO2pre/SpO2post) were measured by pulse oximetry. Cerebral (rSO2brain) and pre/postductal peripheral muscle tissue oxygenation (rSO2pre/rSO2post) were measured by near infrared spectroscopy during the first 15min of life. RESULTS All neonates in both groups experienced normal postnatal transition with normal Apgar scores (Apgar 9/10/10) and with no events of apnea or bradycardia induced by suctioning. SpO2pre values were slightly lower at 2 and 4min after birth. Suctioning had no main and interaction effect on HR, SpO2post, rSO2brain, rSO2pre and rSO2post in the first 15min after birth. CONCLUSION In the present study we were able to show that, in term neonates, when correctly indicated, immediate postnatal oropharyngeal suctioning does not compromise cerebral and peripheral muscle tissue oxygenation. However, any suction maneuver must be performed with caution and strict indication during neonatal transition.
