IPSA Congress 2014 - Porto Alegre - Brazil - Sunday, September 29, 2013

It is my pleasure to present the
III Congress of the International Pediatric Sleep Association (IPSA) - Porto Alegre (Brazil) 3-5 December 2014.

The importance of sleep for health, learning and psychomotor development in infancy, childhood and adolescence has been emphasized in the pediatric research in the last two decades and it has become more and more evident that ensuring a good sleep during development is of key importance for a later healthy life.
The IPSA Congress is an influential forum for sleep practitioners from around the world to network and exchange views, whilst learning from world-class researchers about the latest scientific and clinical developments in the field.
The success of the last two Congresses in Rome 2010 and Manchester 2012 has highlighted the magnitude of Pediatric Sleep Medicine in the scientific community and we hope that the 2014 Congress will provide a perfect balance between didactic and practical needs, in order to provide the technical knowhow and up-to-date knowledge that will enable participants to improve their practice.
As traditional for IPSA, the most renowned International opinion leaders in the field of Pediatric Sleep Medicine speakers will join the Congress and will highlight the recent significant advances in both basic science and clinical sleep medicine during development.
I hope that the world paediatric sleep community will gather together in the lively city of Porto Alegre to celebrate the best clinical practice and the latest advances in Pediatric Sleep Medicine.

Propofol-remifentanil TCI sedation for oral surgery.

N Z Dent J. 2014 Sep;110(3):85-9

Authors: Nagels AJ, Bridgman JB, Bell SE, Chrisp DJ

BACKGROUND AND OBJECTIVES: To investigate the safety and efficacy of a propofol-remifentanil target controlled infusion (TCI) sedation technique for oral surgery.
METHODS: This prospective study involved patient and registered nurse (RN) questionnaires to assess the efficacy of sedation during surgery. Outpatients having dental extractions in a private office-based practice with TCI sedation were monitored with a Sleep Apnoea Monitor (SAM) to measure the number of Oxygen Desaturation Events (ODEs), defined as a drop in blood oxygenation to below 94%.
RESULTS: Patient- and RN-assessed questionnaires showed a high standard of perceived sedation efficacy, independent of patient BMI. The proportion of patients having one or more ODEs was greater in higher BMI categories: underweight (20.0%), normal (47.9%), overweight (68.2%) and obese (81.8%). The odds of at least one ODE was estimated to be 1.2 times greater for each unit increase in BMI (OR 1.2; 95% CI 1.1-1.3), and at a fixed BMI, the odds of at least one ODE was estimated to be 2.6 times as great for a male as a female (OR 2.6; 95% CI 1.2-5.52). Age, patient nervousness and American Society of Anesthesiologists (ASA) classification were not associated with ODEs.
CONCLUSIONS: The TCI technique had a high standard of efficacy, and there were no adverse safety outcomes. Higher BMI and male sex were found to be independently associated with predictors of ODEs during oral surgery under propofol-remifentanil TCI sedation.

[The influence of an improvement of body contact on regulatory disorders in infancy].

Z Kinder Jugendpsychiatr Psychother. 2014 Sep;42(5):301-13

Authors: Streit U, Nantke S, Jansen F, Wolf K, Gallasch M, Kohlmann T

OBJECTIVE: This study concerns the influence of an improvement of body contact on regulatory disorders in infancy. Two interventions were examined: 1. parent counseling on the subject of body contact; 2. practical training of body contact in connection with exposure. Both methods were supplemented by a video-based parent training.
METHODS: 20 infants with regulatory disorder were assigned to each treatment. Body and eye contact were examined by means of video ratings before and after treatment. In addition, we measured the daily amount of crying, sleeping, feeding, being fussy, and quiet play by means of an infant behavior diary.
RESULTS: Both interventions resulted in an improvement of body contact, though only in the group with practical training was this improvement stable after 3 months. Taking all 40 participating infants together, we found significant improvements for "fussiness," "sleep duration," "awake, quiet or playing," and a marginal significant intervention effect for the duration of crying. Both interventions showed that children who had markedly improved in body contact also improved with regard to the regulation problem. Finally, the practical training of body contact was superior to pure counseling respective to the fussiness of the infants and to their gaze contact.
CONCLUSIONS: Body contact can be improved through specific therapeutic interventions. Video-based parent training in combination with interventions aiming at an improvement of body contact have a positive effect on the regulation problem.

Insufficient sleep in adolescents and young adults: an update on causes and consequences.

Pediatrics. 2014 Sep;134(3):e921-32

Authors: Owens J, Adolescent Sleep Working Group, Committee on Adolescence

Chronic sleep loss and associated sleepiness and daytime impairments in adolescence are a serious threat to the academic success, health, and safety of our nation's youth and an important public health issue. Understanding the extent and potential short- and long-term repercussions of sleep restriction, as well as the unhealthy sleep practices and environmental factors that contribute to sleep loss in adolescents, is key in setting public policies to mitigate these effects and in counseling patients and families in the clinical setting. This report reviews the current literature on sleep patterns in adolescents, factors contributing to chronic sleep loss (ie, electronic media use, caffeine consumption), and health-related consequences, such as depression, increased obesity risk, and higher rates of drowsy driving accidents. The report also discusses the potential role of later school start times as a means of reducing adolescent sleepiness.

Cerebral oxygenation in preterm infants.

Pediatrics. 2014 Sep;134(3):435-45

Authors: Fyfe KL, Yiallourou SR, Wong FY, Odoi A, Walker AM, Horne RS

BACKGROUND AND OBJECTIVE: Prone sleeping is a major risk factor for sudden infant death syndrome (SIDS) and preterm infants are at significantly increased risk. In term infants, prone sleeping is associated with reduced mean arterial pressure (MAP) and cerebral tissue oxygenation index (TOI). However, little is known about the effects of sleeping position on TOI and MAP in preterm infants. We aimed to examine TOI and MAP in preterm infants after term-equivalent age, during the period of greatest SIDS risk.
METHODS: Thirty-five preterm and 17 term infants underwent daytime polysomnography, including measurement of TOI (NIRO-200 spectrophotometer, Hamamatsu Photonics KK, Japan) and MAP (Finapress Medical Systems, Amsterdam, Netherlands) at 2 to 4 weeks, 2 to 3 months, and 5 to 6 months postterm age. Infants slept prone and supine in active and quiet sleep. The effects of sleep state and position were determined by using 2-way repeated measures analysis of variance and of preterm birth by using 2-way analysis of variance.
RESULTS: In preterm infants, TOI was significantly lower when prone compared with supine in both sleep states at all ages (P < .05). Notably, TOI was significantly lower in preterm compared with term infants at 2 to 4 weeks, in both positions (P < .05), and at 2 to 3 months when prone (P < .001), in both sleep states. MAP was also lower in preterm infants in the prone position at 2 to 3 months (P < .01).
CONCLUSIONS: Cerebral oxygenation is reduced in the prone position in preterm infants and is lower compared with age-matched term infants, predominantly in the prone position when MAP is also reduced. This may contribute to their increased SIDS risk.

School start times for adolescents.

Pediatrics. 2014 Sep;134(3):642-9

Authors: Adolescent Sleep Working Group, Committee on Adolescence, Council on School Health

The American Academy of Pediatrics recognizes insufficient sleep in adolescents as an important public health issue that significantly affects the health and safety, as well as the academic success, of our nation's middle and high school students. Although a number of factors, including biological changes in sleep associated with puberty, lifestyle choices, and academic demands, negatively affect middle and high school students' ability to obtain sufficient sleep, the evidence strongly implicates earlier school start times (ie, before 8:30 am) as a key modifiable contributor to insufficient sleep, as well as circadian rhythm disruption, in this population. Furthermore, a substantial body of research has now demonstrated that delaying school start times is an effective countermeasure to chronic sleep loss and has a wide range of potential benefits to students with regard to physical and mental health, safety, and academic achievement. The American Academy of Pediatrics strongly supports the efforts of school districts to optimize sleep in students and urges high schools and middle schools to aim for start times that allow students the opportunity to achieve optimal levels of sleep (8.5-9.5 hours) and to improve physical (eg, reduced obesity risk) and mental (eg, lower rates of depression) health, safety (eg, drowsy driving crashes), academic performance, and quality of life.

Night-time experiences and daytime dissociation: a path analysis modeling study.

Psychiatry Res. 2014 May 15;216(2):236-41

Authors: van Heugten-van der Kloet D, Merckelbach H, Giesbrecht T, Broers N

Dissociative symptoms may be the by-products of a labile sleep-wake cycle (Koffel and Watson, 2009a). This may help to explain why dissociation overlaps with fantasy proneness and cognitive failures. Using path analysis, we tested to what extent data gathered in a nonclinical, predominantly female sample (N=139) supported two conceptual models. The first model assumes that unusual sleep experiences increase fantasy proneness and cognitive failures, which in turn encourage trait dissociation and reports of trauma. The second model assumes that trauma leads to dissociative experiences both directly and through its influence on sleep. In this cross-sectional design, the data were reasonably well described by both models. Importantly, in both models, unusual sleep experiences serve as antecedents of trait dissociation. Our analysis underlines the importance of unusual sleep experiences and may inspire treatment intervention focusing on sleep normalization.

Sleep EEG composition in the first three months of life in monozygotic and dizygotic twins.

Clin EEG Neurosci. 2014 Jul;45(3):193-200

Authors: Vucinovic M, Kardum G, Bonkovic M, Resic B, Ursic A, Vukovics J

We investigated genetic influence on sleep electroencephalogram (EEG) composition by a classical twin study of monozygotic (MZ) and dizygotic (DZ) twins in the first 3 months of life. Polysomnographic (PSG) recordings were obtained in 10 MZ and 20 DZ twin pairs in the 37th, 46th, and 52nd week of postmenstrual age (PMA). The EEG power spectra were generated on the basis of fast Fourier transformation (FFT). Genetic influence on active sleep/rapid eye movement (AS/REM)] and quiet sleep/non rapid eye movement (QS/NREM) sleep composition was estimated by calculating within pair concordance and the intraclass correlation coefficients (ICCs) for delta (0.5-3.5 Hz), theta (4-7.5 Hz), alpha (8-11.5 Hz), sigma (12-14 Hz), and beta (14.5-20 Hz) at central derivation. MZ twins show higher ICCs than DZ twins for alpha, sigma, and beta spectral powers during QS/NREM sleep in the 37th, 46th, and 52nd week PMA. However, there was no significant difference (P > .05) between the 2 types of twins in absolute differences of EEG spectral power of the alpha, beta, and sigma frequency ranges in the 37th, 46th, and 52nd week PMA. The greatest mean absolute difference within MZ and DZ twin pairs and also between MZ and DZ twin groups was identified in the delta frequency range. Our findings gave an indication of genetic influence on alpha, sigma, and beta frequency ranges in the QS/NREM sleep stage.
