Symptoms upon postural change and orthostatic hypotension in adolescents with concussion.

Objective: Concussion is associated with dysautonomia, altered blood pressure (BP) control, and may cause Orthostatic Hypotension (OH). We measured prevalence of OH using the 1-minute supine-to-standing OH Test in adolescents with concussion and controls.Participants: Adolescents within 10 days of injury (Concussion Group, n = 297, 15.0 ± 1.7 years, 59% male) were compared with controls (Control Group, n = 214, 15.0 ± 1.5 years, 58% male).Methods: BP, heart rate (HR), and complaints of lightheadedness/dizziness were measured after 2-minute supine and 1-minute standing. Control Group was assessed once. Concussion Group was assessed twice; (1) initial visit (mean 6.0 ± 3 days-since-injury) and (2) after clinical recovery (mean 46.3 ± 42 days-since-injury).Results: Initial visit; Concussion Group reported feeling lightheaded/dizzy on postural change more often than the Control Group (37% vs 4%, p < .001) but did not differ in meeting standard OH criteria (3% vs 5%, p = .32). Experiencing symptoms did not correlate with meeting OH criteria, but correlated with abnormal vestibulo-ocular reflex. After clinical recovery; Concussion Group did not differ in experiencing lightheaded/dizziness on postural change than controls (4%, p = .65).Conclusion: Adolescents commonly experience orthostatic intolerance after concussion without meeting the standard criteria for OH.

"When a Tihik drinks kaxmuk he neither has a father, nor a mother, or a brother": perceptions of Maxakali on the effects of sugarcane liquor consumption. / "Tihik quando bebe Kaxmuk não tem pai, nem mãe, nem irmão": Percepções sociais das consequências do uso da cachaça no povo indígena Maxakali/MG/Brasil.

This study explores one of the most interesting and least studied issues in Brazil: the consequences of complex and contradictory experiences by replacing the traditional drinks by cachaça, introduced through interethnic contact. Given the rarity of the study of Maxakali alcohol consumption in research, this study aims to understand, from the native's point of view, the negative aftereffect of alcohol consumption. Although anthropological studies emphasize functions of traditional and contemporary drinking as social "lubricants", social perceptions of the Maxakali highlight the problems of cachaça bought through interethnic contact. Symbols and meanings of these consequences were interpreted through their daily life histories, recorded by 21 leaders in focus group. Through the interethnic contact, some adaptations have occurred in the Maxakali alcohol use, with negative consequences for those who drink, their families, their villages and their community. In the world-of-life, these changes these changes can be seen through accidents, insults, marital disharmony, neglects, violent behavior, illness and death. This study's findings highlight the importance of producing comprehensive and in-depth knowledge in search of to identify vulnerable groups and to develop participatory solutions.

Este artigo explora um dos aspectos mais interessantes e menos estudados no Brasil: as consequências das experiências complexas e contraditórias da substituição total de bebidas tradicionais indígenas pela cachaça, introduzida pelo contato interétnico. Contribui com a carência de ampliação de estudos na temática, analisando as consequências negativas do uso de álcool Maxakali. Enquanto estudos antropológicos enfatizam funções do beber tradicional e contemporâneo como "lubrificantes" sociais, as percepções sociais Maxakali ressaltam consequências negativas do uso da cachaça vendida ou trocada no contato interétnico. Interpretou-se no cotidiano, símbolos e significados dessas consequências, narradas por 21 lideranças em grupos focais. Com a substituição da Kaxmuk pelos Maxakali, ocorreram adaptações surgidas pelo contato interétnico, com relações negativas para quem bebe, suas família, aldeia e comunidade. No mundo-da-vida, as consequências negativas apresentaram-se em forma de acidentes, desarmonias conjugais, negligências, além de comportamentos violentos, doenças e mortes. Este estudo reforça a importância de produção de conhecimentos aprofundados e abrangentes visando a identificação de grupos vulneráveis em busca de soluções participantes.
