ABSTRACT
BACKGROUND: Cystic periventricular leukomalacia (cPVL) is a strong indicator of subsequent motor and developmental impairments in premature infants. There is a paucity of publications on biomarkers of cPVL. OBJECTIVES: To determine C-reactive protein (CRP) levels during the first week of life of preterm infants who later developed cPVL and to identify the association between CRP levels with perinatal factors. METHODS: We retrospectively included infants ≤ 32 weeks gestation and/or birth weights ≤ 1500 grams; 17 with a cranial ultrasound diagnosis of cPVL and 54 with normal ultrasounds. Serum CRP levels were measured during days 1-7 (CRP1-7d) of life and subdivided into two timing groups: days 1-3 (CRP1-3d) and days 4-7 (CRP4-7d). RESULTS: The cPVL group had significantly higher mean CRP4-7d levels compared to controls (12.75 ± 21.2 vs. 2.23 ± 3.1, respectively, P = 0.03), while CRP1-3d levels were similar. CRP1-7d levels were significantly correlated with maximal fraction of inspired oxygen during the first 12 hours of life (FiO2-12h, r = 0.51, P < 0.001]. Additional risk factors were not associated with CRP levels. CONCLUSIONS: Our finding of elevated CRP4-7d levels and later development of cPVL supports earlier studies on the involvement of inflammation in the pathogenesis of cPVL. Whether CRP could serve as a biomarker of cPVL and its correlation with outcomes, awaits further trials. Furthermore, the correlation between FiO2-12h and CRP1-7d levels suggest that hypoxia and/or hyperoxia may serve as a trigger in the activation of inflammation during the first days of life of preterm infants.

LAY ABSTRACT: Children and youth with autism use screens in their daily lives and in their rehabilitation programs. Although parents and clinicians experience specific challenges when supporting positive screen time use of children and youth with autism, no detailed information for this group exists. Therefore, this study aimed to develop clear guidelines that are agreed by expert clinicians and parents of children and youth with autism. Using a method called Delphi, 30 experts-20 clinicians and 10 caregivers, who have experience working with or caring for children and youth with autism were invited to complete a series of three surveys. In each round, the experts had to rate their agreement with statements regarding screen time management. The agreement level was set to 75%. The final themes to be included in the guidelines were accepted by more than 75% of the panel. The final guidelines included six main sections: (1) general principles, (2) considerations for timing and content of leisure screen time use, (3) strategies for caregivers and clinicians to monitor and regulate screen time use, (4) behaviors to monitor for screen time overuse, (5) additional guidelines for clinicians, and (6) resources. The new guidelines developed in this study can provide potential guidance on how to further the development of digital citizenship for children and youth with autism and provide strategies to families to help manage screen time use.
