Summary There are many unanswered questions about the population history of the Central and South Central Andes, particularly regarding the impact of large-scale societies, such as the Moche, Wari, Tiwanaku, and Inca. We assembled genome-wide data on 89 individuals dating from ∼9,000-500 years ago (BP), with a particular focus on the period of the rise and fall of state societies. Today’s genetic structure began to develop by 5,800 BP, followed by bi-directional gene flow between the North and South Highlands, and between the Highlands and Coast. We detect minimal admixture among neighboring groups between ∼2,000–500 BP, although we do detect cosmopolitanism (people of diverse ancestries living side-by-side) in the heartlands of the Tiwanaku and Inca polities. We also highlight cases of long-range mobility connecting the Andes to Argentina and the Northwest Andes to the Amazon Basin. Video Abstract

Narcolepsy, a chronic disorder of the sleep–wake cycle of multifactorial etiology, is characterized by excessive daytime sleepiness, often associated with cataplexy, hypnagogic/hypnopompic hallucinations and sleep paralysis. Both early clinical suspicion and therapeutic approach are essential for promotion of cognitive development and social integration of these children. The authors present a descriptive retrospective study of a series of eight children in whom symptoms first started between 6.8 and 10.5 years of age. Diagnostic delay ranged from 4 months to 2 years. One child had H1N1 flu vaccination eight months before the clinical onset. The first multiple sleep latency test was positive in 6 of 8 cases. All cases were treated with methylphenidate, and venlafaxine was associated in 4 of them. In one case the initial therapy was exclusively behavioral. In all cases, symptomatic improvement, better school performance and social integration were achieved after therapeutic adjustment.

Introduction: According to the Convention on the Rights of Children and the national standards of the Portuguese Directorate-General for Health, adolescents have the right to make decisions about their own health. The aim of this study was to identify the dynamics of the implementation of assent and informed consent in hospital settings.Material and Methods: Cross-sectional and multicentre study based on surveys, which included adolescents from 14 to 18 years and their parents. Heads of departments of Pediatrics and attending physicians were also interviewed.Results: 194 responses from adolescents and parents were collected, and 46 interviews were conducted with physicians and heads of department. Adolescents and parents consider participation in decision making important, but parents value their own participation significantly higher (91.7% vs 47.8%, p < 0.001 in the 14 - 15 year group, 91.8% vs 53, (89.6% vs 69.6%, p = 0.016 in the 14 - 15 year group, 91.8% vs 69.4%, p = 0.005 in the 16 - 17 years group). Information leaflets are difficult to understand by teenagers. The eight heads of department felt that doctors have awareness towards communication with teenagers but have little time available. Of the 38 attending physicians, 36 said they had learned from their older colleagues and confirmed gaps in postgraduate training.Discussion: This pioneering study in Portugal enabled the identification of areas that can be optimized, through health education programs for parents and adolescents, written information that is adequate to the different age groups, training in undergraduate education for medical students and also education in health institutions for professionals.Conclusion: Adolescents and parents, are unaware of legal and ethical standards for consent and assent. The implementation of the adolescents’ right to informed assent / informed consent was not observed. Our proposal is to implement local programs for adolescents and parents.
