As (des)construções identitárias: reflexões sobre os povos indígenas na Amazônia / Identity (de)constructions: reflections on indigenous peoples in the Amazon

Este trabalho visa provocar um debate sobre os processos identificatórios em relação às populações indígenas na Amazônia. A violência de atos discriminatórios que se opera em relação a essa parcela da população brasileira, está presente desde os tempos coloniais e continuam no presente. Neste recorte, representado pela história de Mary, uma indígena da etnia Tembé, no Estado do Pará, emerge de sua escuta singular, o conflituoso laço com o social dominador. Seguiremos o enfoque psicanalítico(AU)

Ritos de passagem: o lugar da adolescência nas sociedades indígenas Tembé Tenetehara e Kaxuyana / Rites of passage: the place of adolescence in Tembe Tenetehara and Kaxuyana indigenous societies

A puberdade representa uma experiência de rupturas e transformações, que pode causar conflitos. Nas sociedades indígenas Tembé e Kaxuyana nos Estados do Pará e Amapá, a chegada da puberdade é marcada por ritos de passagem que introduzem a criança no mundo adulto, sem a inserção na adolescência como definido na cultura ocidental do não índio. Os impasses parecem decorrer do choque entre seus códigos simbólicos com os do não índio. O texto propõe uma leitura sobre a puberdade dentro de uma perspectiva psicanalítica(AU)

The puberty is an experience about disruptions and transformations, which can cause conflictis. Among Tembé and Kauyana indigenous societies in the states of Pará and Amapa, the arrival of puberty is marked by rits of passage that introduce the child in the adult world, without the inclusion in adolescense as defined in western culture of non-indian. Deadloks appear during the clash between their symbolic codes with the non-indian. The text proposes a reflection on puberty within a psychoanalitc perspective(AU)

Does Caffeine Consumption Modify Cerebrospinal Fluid Amyloid-ß Levels in Patients with Alzheimer's Disease?

Caffeine may be protective against Alzheimer's disease (AD) by modulating amyloid-ß (Aß) metabolic pathways. The present work aimed to study a possible association of caffeine consumption with the cerebrospinal fluid (CSF) biomarkers, particularly Aß. The study included 88 patients with AD or mild cognitive impairment. The consumption of caffeine and theobromine was evaluated using a validated food questionnaire. Quantification of caffeine and main active metabolites was performed with liquid chromatography coupled to tandem mass spectrometry. The levels of A(1-42), total tau, and phosphorylated tau in the CSF were determined using sandwich ELISA methods and other Aß species, Aß(X-38), Aß(X-40), and Aß(X-42), with the MSD Aß Triplex assay. The concentration of caffeine was 0.79±1.15 µg/mL in the CSF and 1.20±1.88 µg/mL in the plasma. No correlation was found between caffeine consumption and Aß42 in the CSF. However, a significant positive correlation was found between the concentrations of theobromine, both in the CSF and in the plasma, with Aß42 in the CSF. Theobromine in the CSF was positively correlated with the levels of other xanthines in the CSF, but not in the plasma, suggesting that it may be formed by central metabolic pathways. In conclusion, caffeine consumption does not modify the levels of CSF biomarkers, and does not require to be controlled for when measuring CSF biomarkers in a clinical setting. Since theobromine is associated with a favorable Aß profile in the CSF, the possibility that it might have a protective role in AD should be further investigated.

Clinical manifestations associated with HTLV type I infection: a cross-sectional study.

Human T-lymphotropic virus type I (HTLV-I) causes HTLV-I-associated myelopathy/tropical spastic paraparesis and adult T cell leukemia in a small percentage of infected individuals. HTLV-I infection is increasingly associated with clinical manifestations. To determine the prevalence of clinical manifestations in HTLV-I infected individuals, we conducted a cross-sectional study of 115 HTLV-I-infected blood donors without myelopathy and 115 age- and sex-matched seronegative controls. Subjects answered a standardized questionnaire and underwent physical examination. Compared with controls, HTLV-I-infected subjects were more likely to report arm or leg weakness (OR = 3.8, 95% CI: 1.4-10.2; OR = 4.0, 95% CI: 1.6-9.8, respectively), hand or foot numbness (OR = 2.1, 95% CI: 1.1-3.9; OR = 4.8, 95% CI: 2.0-11.7, respectively), arthralgia (OR = 3.3, 95% CI: 1.7-6.4), nocturia (OR = 2.7, 95% CI: 1.04-6.8), erectile dysfunction (OR = 4.0, 95% CI: 1.6-9.8), and to have gingivitis (OR = 3.8, 95% CI: 1.8-7.9), periodontitis (OR = 10.0, 95% CI: 2.3-42.8), and dry oral mucosa (OR = 7.5, 95% CI: 1.7-32.8). HTLV-I infection is associated with a variety of clinical manifestations, which may occur in patients who have not developed myelopathy.
