RESUMEN
OBJECTIVE: To examine whether parenteral nutrition using a mixed lipid emulsion containing fish oil improves the neurodevelopmental outcomes of extremely low birth weight infants. STUDY DESIGN: The study is a secondary outcome analysis of a double-blind randomized trial of 230 extremely low birth weight infants performed at a single level IV neonatal care unit (Medical University Vienna; June 2012 to June 2015). Participants received either a mixed lipid emulsion composed of soybean oil, medium chain triglycerides, olive oil, and fish oil, or a soybean oil-based lipid emulsion for parenteral nutrition. Neurodevelopment of study participants was assessed at 12 and 24 months corrected age (August 2013 to October 2017) using the Bayley Scales of Infant-Toddler Development, third edition. RESULTS: At discharge, 206 of the 230 study participants were eligible. At 12 and 24 months corrected age, 174 of 206 (85%) and 164 of 206 (80%) infants were evaluated. At 12 months, there was no significant difference in cognitive (mixed lipid: median, 95 [IQR, 85-101]; soybean oil: median, 95 [IQR, 85-100]; P = .71), language (mixed lipid: median, 86 [IQR, 77-94], soybean oil: median, 89 [IQR, 79-94]; P = .48), or motor scores (mixed lipid: median, 88 [IQR, 76-94], soybean oil: median, 88 [IQR, 79-94]; P = .69). At 24 months, there was again no significant difference in cognitive (mixed lipid: median, 95 [IQR, 80-105], soybean oil: median, 95 [IQR, 90-105]; P = .17), language (mixed lipid: median, 89 [IQR, 75-97], soybean oil 89 [IQR, 77-100]; P = .54), and motor scores (mixed lipid: median, 94 [IQR, 82-103], soybean oil: median, 94 [IQR, 85-103]; P = .53). CONCLUSIONS: Parenteral nutrition using a mixed lipid emulsion containing fish oil did not improve neurodevelopment of extremely low birth weight infants at 12 and 24 months corrected age. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01585935.

Objective: Very low birthweight (VLBW) infants have an increased risk of mortality and frequently suffer from complications, which affects parental occupational balance. Occupational balance is the satisfaction with one's meaningful activities, which include everyday activities that people need to, want to, and are expected to do. In contrast to work-life balance, the construct of occupational balance addresses different activities equally and it applies to all persons, regardless of whether they are working or not. Parental occupational balance might be related to parents' and VLBW infants' health. Therefore, the objective of this study was to investigate associations between parental occupational balance, subjective health, and clinical characteristics of VLBW infants. Methods: A cross-sectional multicenter study was conducted in six Austrian neonatal intensive care units. Occupational balance and subjective health of parents of VLBW infants were assessed with six self-reported questionnaires. The following clinical characteristics of VLBW infants were extracted from medical records: gestational age, birthweight, Apgar scores, Clinical Risk for Babies II Score, and complications of prematurity. Spearman's rank coefficients were calculated. Results: In total, 270 parents, 168 (62%) female and their VLBW infants, 120 (44%) female, were included in this study. Parents' mean age was 33.7 (±6.0) years, mean gestational age of VLBW infants was 27 + 3 (±2) weeks. Associations between parental occupational balance, subjective health, and clinical characteristics of VLBW infants were identified (r s = 0.13 - 0.56; p ≤ 0.05), such as the correlation between occupational areas (r s = 0.22, p ≤ 0.01), occupational characteristics (r s = 0.17, p = 0.01), and occupational resilience (r s = 0.18, p ≤ 0.01) with bronchopulmonary dysplasia of VLBW infants. Conclusion: Occupational balance is associated with parents' and VLBW infants' health. Interventions to strengthen parental occupational balance might increase parental health and thereby also improve health and developmental outcomes of their VLBW infants.
RESUMEN
OBJECTIVE: The aim of the study was to determine the predictive power of the combined use of neurophysiological (amplitude-integrated electroencephalography [aEEG], near-infrared spectroscopy [NIRS]) methods and neuroimaging (magnetic resonance imaging [MRI]) for long-term outcome prediction in neonates with hypoxic-ischaemic encephalopathy (HIE). STUDY DESIGN: Prospective cohort study of 56 patients with moderate to severe HIE and hypothermia treatment at the Medical University of Vienna between 2008 and 2020. aEEG and NIRS were recorded continuously over a period of >4 days (102 h) starting at the initiation of hypothermia treatment, MRI was performed at a median age of 8 days. Receiver operating characteristic curves and area under the curve were calculated to evaluate the prognostic ability of aEEG, NIRS, and MRI parameters for outcome assessed via Bayley Scales of Infant Development 3rd edition at 2 years of age. RESULTS: Combined aEEG and MRI parameters showed highest predictive power regarding long-term outcome. The highest area under the curve values (0.96-0.99) were obtained for aEEG (combination of background pattern and sleep-wake cycling) between 66 and 102 h after initiation of hypothermia in combination with MRI findings. NIRS parameters did not differ significantly between infants with favourable and adverse outcome. CONCLUSIONS: Combined aEEG and MRI parameter scores were more predictive than single parameter scores. No further improvement was observed when combining aEEG/MRI with NIRS data.

BACKGROUND: Parents' meaningful activities (occupations) and occupational balance are relevant to neonatal care. Valid and reliable self-reported measurement instruments are needed to assess parents' occupational balance and to evaluate occupational balance interventions in neonatal care. The aims of this study were to develop a self-reported questionnaire on occupational balance in informal caregivers (OBI-Care) and to examine its measurement properties including construct validity and internal consistency. METHODS AND FINDINGS: A mixed method multicenter study design was employed. Items of the OBI-Care were created with parents of preterm infants based on qualitative research methods. Measurement properties were analyzed with quantitative data of parents of preterm infants. Construct validity was assessed by determining dimensionality, overall and item fit to a Rasch model, differential item functioning and threshold ordering. Internal consistency was examined by determining inter-item and item-total correlations, Cronbach's alpha and Rasch's person separation index. Fourteen parents participated in item creation. Measurement properties were explored in data of 304 parents. Twenty-two items, summarized in three subscales were compiled to the OBI-Care. Items showed an overall fit and except one item, an item fit to the Rasch model. There was no evidence of differential item functioning and all items displayed ordered thresholds. Each subscale had good values of person separation indices and Cronbach's alpha. CONCLUSIONS: The OBI-Care demonstrates construct validity and internal consistency and is thus a suitable measurement instrument to assess occupational balance of parents of preterm infants in neonatal care. OBI-Care is generic and can be applied in various health care settings.

BACKGROUND: The Bayley Scales of Infant and Toddler Development, third edition (Bayley-III) are widely used to assess the development of children born preterm. However, it is still unclear whether US norms are adequate for use in other populations. In 2014, the German version of the Bayley-III with German norms was published. OBJECTIVES: We aimed to compare the performance of very-preterm infants at one, two, and three years of age using the German versus US norms of the Bayley-III. METHODS: All children born prior to 32 weeks of gestational age during 2012 and 2015 and taking part in the follow-up program of the Medical University of Vienna were assessed and scored according to both German and US norms by two expert clinical psychologists at the age of one, two, and three years of age. RESULTS: In total, 843 tests were obtained from 450 children. When looking at scaled scores for cognitive, language, and motor outcomes, preterm children achieved significantly lower scores in nearly all subtests with the German as compared to the US norms. In addition, the proportion of impaired children scoring < 1 standard deviation (SD) and < 2 SD below the norm was significantly higher in nearly all subtests when using the German compared to the US norms (p < 0.05). CONCLUSIONS: Applying German and US norms of the Bayley-III leads to different outcomes in very-preterm children, and these differences are statistically significant and clinically relevant. Thus, comparisons of outcomes of very-preterm children using culturally specific norms are problematic, and these findings have to be considered.

INTRODUCTION: Parents have a major impact on the outcome of health care of preterm infants. Parents' engagement in meaningful activities could have an impact on their own health and wellbeing and therefore be relevant in neonatal intensive care. The aim of this study was to explore meaningful activities of parents of very low birth weight (VLBW) preterm infants with the purpose to further the understanding of their clinical relevance and to foster their consideration in clinical practice and research of neonatal intensive care. METHODS: A total of 36 parents of preterm infants born prior to complete 37 weeks of gestation with VLBW (≤1.500 grams) were asked to participate in a focus group interview. Interview transcripts were used to analyse the content of the focus group interviews using meaning condensation method by Steinar Kvale. RESULTS: Thirty-six parents participated in a total of twelve focus groups. Parents reported that the meaning of certain activities changed due to preterm birth. Meaningful activities, like bathing the baby and gardening, could foster a transition from a feeling of parental immaturity to a feeling of maturity, following health care instructions to possessing health care skills, and a functioning-only state to a balance of activities. CONCLUSIONS: In neonatal intensive care, nurses contribute to delivering parental education and thereby facilitate experiences of being a mature parent and of possessing health care skills. Occupational therapy could be used to help re-engage in meaningful activities and maintain a balance of activities in parents of VLBW preterm infants.
