A multinational, collaborative, biomedical investigation of the effects of hoasca (ayahuasca), a potent concoction of plant hallucinogens, was conducted in the Brazilian Amazon during the summer of 1993. This report describes the psychological assessment of 15 long-term members of a syncretic church that utilizes hoasca as a legal, psychoactive sacrament as well as 15 matched controls with no prior history of hoasca ingestion. Measures administered to both groups included structured psychiatric diagnostic interviews, personality testing, and neuropsychological evaluation. Phenomenological assessment of the altered state experience as well as semistructured and open-ended life story interviews were conducted with the long-term use hoasca group, but not the hoasca-naive control group. Salient findings included the remission of psychopathology following the initiation of hoasca use along with no evidence of personality or cognitive deterioration. Overall assessment revealed high functional status. Implications of this unusual phenomenon and need for further investigation are discussed.
Summary: Purpose:The worldwide prevalence of epilepsy is variable, estimated at 10//1,000 people, and access to treatment is also variable. Many people go untreated, particularly in resourcepoor countries.Objective: To estimate the prevalence of epilepsy and the proportion of people not receiving adequate treatment in different socioeconomic classes in Brazil, a resource-poor country.Methods: A door-to-door survey was conducted to assess the prevalence and treatment gap of epilepsy in three areas of two towns in Southeast Brazil with a total population of 96,300 people. A validated screening questionnaire for epilepsy (sensitivity 95.8%, specificity 97.8%) was used. A neurologist further ascertained positive cases. A validated instrument for socioeconomic classification was used.Results: Lifetime prevalence was 9.2/1,000 people [95% CI 8.4-10.0] and the prevalence of active epilepsy was 5.4/1,000 people. This was higher in the more deprived social classes (7.5/1,000 compared with 1.6/1,000 in the less deprived). Prevalence was also higher in elderly people (8.5/1,000). Thirty-eight percent of patients with active epilepsy had inadequate treatment (19% on no medication); the figures were similar in the different socioeconomic groups.Conclusion: The prevalence of epilepsy in Brazil is similar to other resource-poor countries, and the treatment gap is high. Epilepsy is more prevalent among less wealthy people and in elderly people. There is an urgent need for education in Brazil to inform people that epilepsy is a treatable, as well as preventable, condition.
OBJECTIVE:Depression is the most important neuropsychiatric complication in chronic kidney disease because it reduces quality of life and increases mortality. Evidence demonstrating the association between dialysis shift and depression is lacking; thus, obtaining such evidence was the main objective of this study.METHOD:This cross-sectional study included patients attending a hemodialysis program. Depression was diagnosed using Beck's Depression Inventory. Excessive daytime sleepiness was evaluated using the Epworth Sleepiness Scale.RESULTS:A total of 96 patients were enrolled (55 males, age 48±14 years). Depression and excessive daytime sleepiness were observed in 42.7% and 49% of the patients, respectively. When comparing variables among the three dialysis shifts, there were no differences in age, dialysis vintage, employment status, excessive daytime sleepiness, hemoglobin, phosphorus levels, or albumin levels. Patients in the morning shift were more likely to live in rural areas (p<0.0001), although patients in rural areas did not have a higher prevalence of depression (p = 0.30). Patients with depression were more likely to be dialyzed during the morning shift (p = 0.008). Independent risk factors for depression were age (p<0.03), lower levels of hemoglobin (p<0.01) and phosphorus (p<0.01), and dialysis during the morning shift (p = 0.0009). The hospitalization risk of depressive patients was 4.5 times higher than that of nondepressive patients (p<0.008).CONCLUSION:These data suggest that depression is associated with dialysis shift, higher levels of phosphorus, and lower levels of hemoglobin. The results highlight the need for randomized trials to determine whether this association occurs by chance or whether circadian rhythm disorders may play a role.
O estudo objetivou verificar a prevalência de alteração no desenvolvimento neuropsicomotor em lactentes inseridos nas creches públicas de João Pessoa, Paraíba, Brasil, e analisar fatores associados ao desenvolvimento infantil. Realizou-se um estudo seccional com o censo de crianças entre 6 e 18 meses de vida inseridas nas creches. O desenvolvimento infantil foi avaliado pelo Teste de Triagem de Denver II. Variáveis de natureza biológica, materna, social, demográfica e relativas à creche foram investigadas através de questionário e formulário. As associações foram ajustadas por regressão logística. A prevalência de alteração no desenvolvimento foi 52,7%. Associou-se à alteração no desenvolvimento a criança ter mais que 12 meses de idade (RC = 4,3), o parto vaginal (RC = 4,4), a fototerapia (RC = 7,9) e a creche não ter apoio da Estratégia Saúde da Família (RC = 2,9). Os achados sugerem que o desenvolvimento infantil é o reflexo das condições familiares, bem como da assistência recebida pelos serviços de educação e saúde.
