Article Citation - Scopus: 3The Effect of a Light-Dark Cycle on Premature Infants in the Neonatal Intensive Care Unit: a Randomized Controlled Study(W.B. Saunders, 2024) Olgun,A.B.; Yüksel,D.; Yardımcı,F.Purpose: To investigate potential differences in discharge time, feeding methods and amounts, daily weight gain, vital signs, pain, and comfort levels among preterm infants born at 28–32 weeks' gestation who were hospitalized in the neonatal intensive care unit during long-term follow-up while implementing a light-dark cycle. Design and methods: This is a randomized controlled study conducted with the support of a day-night cycle in premature infants born at 28–32 weeks' gestation and admitted to the neonatal intensive care unit of a teaching and research hospital affiliated with the Ministry of Health. The study compared the follow-up results from hospitalization to discharge over a period of 8 weeks. Results: 50% of premature infants admitted to the unit are multiple pregnancies. There was no significant difference in discharge weight, comfort level, pain level, vital signs of the infants included in the study (p > 0.05). The optimal development of infant feeding patterns was examinedand it was observed that the study group had significantly improved before the control group in terms of the time to switch to full enteral feeding and oral feeding (p < 0,05). The daily weight gain of the babies was examined, it was seen that the weight gain was higher in the study group compared to the control group (p < 0,05). The mean duration of hospitalization was compared, it was seen that the babies in the study group were discharged significantly earlier (p < 0,05). Conclusion: The study compared the long-term outcomes of premature babies hospitalized in neonatal intensive care and babies exposed to a light-dark cycle and regularly monitored in standard care. The results showed that the babies in the study group had higher daily weight gain and were discharged earlier than the control group. There were also no statistically significant differences in comfort and pain scores, vital signs or oxygen saturation between the study and control groups. Practice implications: A light-dark cycle was found to be a feasible and promising intervention for infants at 28–32 weeks' gestation. It was a nurse-led management of care that could be integrated into the usual care of 28–32-week-old babies in neonatal units. © 2024Article Citation - WoS: 5Citation - Scopus: 5The psychometric properties of the Turkish version of the Pre-sleep Arousal Scale(Springer Japan Kk, 2024) Turkarslan, Kutlu Kagan; Canel cinarbas, Deniz; Nicassio, Perry M.PurposeThe aim of the present study was to examine the psychometric properties of the Turkish version of the Pre-sleep Arousal Scale (PSAS), which measures pre-sleep arousal, a significant predictor of insomnia symptoms.Methods651 participants were recruited via social media and the Internet. Confirmatory factor analysis was conducted in the total sample (65.28% females; M-age1 = 28.09 & PLUSMN; 14.00). Convergent, divergent, incremental, and known-groups validity and internal consistency coefficients were assessed in a subsample of 556 participants (62.77% females; M-age2 = 29.25 & PLUSMN; 14.81). A second separate sample of 88 participants (80.68% females; M-age3 = 22.19 & PLUSMN; 4.98) was used to evaluate three-week test-retest reliability.ResultsThe results of factor analysis confirmed the two-factor structure of the Turkish PSAS with cognitive (PSAS-C) and somatic (PSAS-S), similar to the original scale. The correlations of the PSAS with convergent and divergent measures showed that the Turkish form had good convergent and acceptable divergent validity. PSAS-C and PSAS-S were able to explain an 18% additional variance in insomnia severity beyond depression and anxiety, an 18% additional variance in depression beyond insomnia severity, and a 35% additional variance in anxiety beyond insomnia severity. Moreover, insomnia patients had significantly higher PSAS-C and PSAS-S scores than good sleepers. Finally, the PSAS, PSAS-C, and PSAS-S had satisfactory internal consistency coefficients (& alpha; = 0.92, 0.91, and 0.86, respectively) and three-week test-retest correlations (ICC = 0.82, 0.82, and 0.71, respectively).ConclusionThe Turkish form of the PSAS was a valid and reliable measure of pre-sleep arousal and can be utilized in sleep studies.Article Citation - WoS: 7Citation - Scopus: 8Do Preterm Babies Sleep Differently Than Their Peers? Sleep Characteristics and Their Associations With Maternal Depression and Parenting Stress(Elsevier, 2022) Akkus, Pinar Zengin; Bahtiyar-Saygan, Bahar; Zengin Akkus, PınarObjectives: The findings regarding the association between prematurity, sleep problems, and maternal psychological well-being are mixed. This study examined preterm- and term-born infants' sleep patterns, ecology, and problems, in addition to the associations of these patterns with maternal parenting stress and depressive symptomatology. Methods: In total, 84 mothers of infants between 6 and 17 months of corrected age, in which 40 were preterm infants and 44 were healthy full-term infants, participated in the study. Children's sleep was evaluated by the Brief Infant Sleep Questionnaire. Maternal depressive symptoms were screened by the Edinburgh Postnatal Depression Scale. Maternal parenting stress was measured via the Parenting Stress Index-Short Form. Results: In preterm infants, lower total and nocturnal sleep duration and later falling asleep time were identified compared to term infants. Regarding sleep ecology, the percentages of poor sleepers, mother's perception of child's and her own sleep problems were similar in both groups. While the most common method of falling asleep was 'rocking the baby' in the preterm group, it was 'breastfeeding' in the term group. In both groups, the maternal perception of sleep problems positively predicted maternal parenting stress. Lastly, compared to good sleepers, higher maternal parenting stress, higher maternal perception of mother's and child's sleep problems, and lower infants' age were identified among poor sleepers. Conclusions: Despite many similarities in the sleep characteristics of preterm and term infants, several differences in sleep patterns and sleep ecology of preterm infants were identified. Since the maternal perception of sleep problems was found to predict parenting stress, guidance on infant sleep is suggested to support families. (C) 2022 Elsevier B.V. All rights reserved.
