Défi verbal et auto-analgésie : une étude psychophysiologique chez les Quichuas

La douleur est une expérience humaine des plus universelles et d’une riche variabilité culturelle. Néanmoins, il y a peu d’études sur ce sujet en général et qui plus est, la recherche sur la douleur chez les Amérindiens est presque inexistante. L’expérience de douleur de quelques 28 millions d’Amérindiens en Amérique du Sud, dont les Quichuas (Inca), est encore méconnue. Cette recherche interdisciplinaire, psychophysiologique et anthropologique, vise deux buts : (1) Étudier les effets de type analgésique du défi verbal culturellement significatif chez les Quichuas ; et (2) Faire un survol de leur système de croyances concernant la douleur, leur façon de la percevoir, de la décrire, et de la contrôler. Pour le volet expérimental, on a recruté 40 hommes en bonne santé. Les volontaires étaient assignés de façon alternée soit au groupe expérimental (20) soit au groupe contrôle (20). On a enregistré chez eux les seuils de la douleur, et celui de la tolérance à la douleur. Chez le groupe expérimental, on a, de plus, mesuré le seuil de la tolérance à la douleur avec défi verbal. La douleur était provoquée par pression au temporal, et mesurée à l’aide d’un algésimètre. Après chaque seuil, on a administré une échelle visuelle analogique. Pour le deuxième volet de l’étude, un groupe de 40 participants (15 femmes et 25 hommes) a répondu verbalement à un questionnaire en quichua sur la nature de la douleur. Celui-ci touchait les notions de cause, de susceptibilité, les caractéristiques de la douleur, les syndromes douloureux, les méthodes de diagnostic et de traitement, ainsi que la prévention. Notre étude a révélé que les participants ayant reçu le défi verbal ont présenté une tolérance accrue à la douleur statistiquement significative. Les valeurs de l’échelle visuelle analogique ont aussi augmenté chez ce groupe, ce qui indique un état accru de conscience de la douleur. L’expérience de la douleur chez les Quichuas est complexe et les stratégies pour la combattre sont sophistiquées. Selon leur théorie, le vécu d’émotions intenses, dues à des évènements de la vie, à l’existence d’autres maladies qui affectent la personne de façon concomitante, et aux esprits présents dans la nature ou chez d’autres personnes joue un rôle dans l’origine, le diagnostic et le traitement de la douleur. Les Quichuas accordent une grande crédibilité à la biomédecine ainsi qu’à la médecine traditionnelle quichua. Ils perçoivent la famille et le voisinage comme étant des sources supplémentaires de soutien. Il ressort également que les Quichuas préfèrent un service de santé de type inclusif et pluraliste. En conclusion, cette étude a révélé que des mots culturellement significatifs ayant une connotation de défi semblent augmenter la tolérance à la douleur chez les Quichuas. Il s’agit de la première étude à documenter les effets analgésiques de la parole. D’autre part, cette étude souligne également la potentielle utilité clinique de connaître le système quichua de croyances entourant la douleur et le contrôle de cette dernière. Ceci s’avère particulièrement utile pour les cliniciens soucieux d’offrir des soins de santé de meilleure qualité, culturellement adaptés, dans les Andes.

Avaliação da autopercepção estética e qualidade de vida em pessoas vivendo com HIV/AIDS com síndrome lipodistrófica (SLD) em uso de antirretrovirais

Em 1996 com a introdução no Brasil da Highly Active Antiretroviral Therapy (HAART) melhorando a sobrevida e diminuindo o número de óbitos entre os portadores do HIV/Aids, surgem relatos de alterações metabólicas e morfológicas - Síndrome Lipodistrófica (SLD). Portanto, este estudo busca avaliar a partir da autopercepção estética de pessoas que vivem com HIV/AIDS (PVHA) em uso de terapia antirretroviral (TARV) o impacto da SLD na qualidade de vida. Pesquisa exploratória observacional com dados quantitativos e qualitativos, que contou com a multidisciplinaridade, a partir dos critérios de inclusão os voluntários eram captados pelo médico infectologista assistente. Foi realizada com base nos princípios da Resolução 196/96-CNP. A amostra foi composta por 48 PVHA, com idade entre 32 a 66 anos. 89,6% demonstraram interesse em mudar partes do corpo que perceberam enquanto alteradas ou comprometidas pela SLD, dado reforçado quando estes afirmam que se percebem (35,4%) e sentem (35,4%) que as outras pessoas os vêem de forma diferente. Quanto a qualidade de vida o domínio da espiritualidade, religião e crenças pessoais alcançou maior média (14,7) com DP 4,0 neste estudo. A pesquisa permitiu uma publicação internacional (Journal of Public Health and Epidemiology-JPHE) e várias participações com publicação em eventos (nacionais e internacionais). O estudo sugere que a infecção por HIV e a presença da SLD a partir da autopercepção dos sujeitos entrevistados pode afetar a qualidade de vida. E destaca a importância de ações que ressaltem o suporte social como motivador para o autocuidado

Neurocysticercosis: The enigmatic disease

Neurocysticercosis (NCC) is an infection of the central nervous system (CNS) caused by the metacestode larval form of the parasite Taenia sp. Many factors can contribute to the endemic nature of cysticercosis. The inflammatory process that occurs in the tissue surrounding the parasite and/or distal from it can result from several associated mechanisms and may be disproportionate with the number of cysts. This discrepancy may lead to difficulty with the proper diagnosis in people from low endemic regions or regions that lack laboratory resources. In the CNS, the cysticerci have two basic forms, isolated cysts (Cysticercus cellulosae = CC) and racemose cysts (Cysticercus racemosus = CR), and may be meningeal, parenchymal, or ventricular or have a mixed location. The clinical manifestations are based on two fundamental syndromes that may occur in isolation or be associated: epilepsy and intracranial hypertension. They may be asymptomatic, symptomatic or fatal; have an acute, sub-acute or chronic picture; or may be in remission or exacerbated. The cerebrospinal fluid (CSF) may be normal, even in patients with viable cysticerci, until the patients begin to exhibit the classical syndrome of NCC in the CSF, or show changes in one or more routine analysed parameters. Computed tomography (CT) and magnetic resonance imaging (MRI) have allowed non-invasive diagnoses, but can lead to false negatives. Treatment is a highly controversial issue and is characterised by individualised therapy sessions. Two drugs are commonly used, praziquantel (PZQ) and albendazole (ABZ). The choice of anti-inflammatory drugs includes steroids and dextrochlorpheniramine (DCP). Hydrocephalus is a common secondary effect of NCC. Surgical cases of hydrocephalus must be submitted to ventricle-peritoneal shunt (VPS) immediately before cysticidal treatment, and surgical extirpation of the cyst may lead to an absence of the surrounding inflammatory process. The progression of NCC may be simple or complicated, have remission with or without treatment and may exhibit symptoms that can disappear for long periods of time or persist until death. Unknown, neglected and controversial aspects of NCC, such as the impaired fourth ventricle syndrome, the presence of chronic brain oedema and psychic complaints, in addition to the lack of detectable glucose in the CSF and re-infection are discussed. © 2011 Bentham Science Publishers.

Variabilidade da frequência cardíaca como recurso em fisioterapia: análise de periódicos nacionais

INTRODUCTION: The autonomic nervous system (ANS) could be investigated in a noninvasive way by the heart rate variability analysis (HRV) which has contributed to several health areas such as physiotherapy. OBJECTIVE: To gather information regarding the use of HRV on physiotherapy aims at providing an update of the findings for the area on journals of national circulation. MATERIALS AND METHODS: The journals of national circulation classified as greater than B2 or B2 and with free access and complete texts in some internet sites were searched on 21 area WebQualis resulting on selection of Revista Brasileira de Fisioterapia, Fisioterapia e Pesquisa and Fisioterapia em Movimento using the keywords: autonomic nervous system, sympathetic nervous system, physiotherapy and heart rate variability. RESULTS: The search resulted in 19 articles being 17 clinical trials and two case reports. CONCLUSION: The HRV has been used as a resource of interventions evaluation, as pathological conditions common to clinical practice investigation and to physiological conditions interpretation in physiotherapy. The HRV is principally used to the cardiorespiratory specialty of physiotherapy.

Staphylococcal enterotoxins: molecular aspects and detection methods

Members of the Staphylococcus genus, especially Staphylococcus aureus, are the most common pathogens found in hospitals and in community-acquired infections. Some of their pathogenicity is associated with enzyme and toxin production. Until recently, S. aureus was the most studied species in the genus; however, in last few years, the rise of infections caused by coagulase-negative staphylococci has pointed out the need for further studies on virulence factors that have not yet been completely elucidated so as to better characterize the pathogenic potential of this group of microorganisms. Several staphylococcal species produce enterotoxins, a family of related proteins responsible for many diseases, such as the toxic-shock syndrome, septicemia and food poisoning. To this date, 23 different enterotoxin types have been identified besides toxic-shock syndrome toxin-1 (TSST-1), and they can be divided into five phylogenetic groups. The mechanism of action of these toxins includes superantigen activity and emetic properties, which can lead to biological effects of infection. Various methods can detect genes that encode enterotoxins and their production. Molecular methods are the most frequently used at present. This review article has the objective to describe aspects related to the classification, structure and regulation of enterotoxins and toxic-shock syndrome toxin-1 detection methods.

Consumo de alimentos de origem animal e câncer de boca e orofaringe

OBJETIVO: Avaliar a relação entre alimentos de origem animal e câncer de boca e orofaringe. MÉTODOS: Estudo caso-controle, de base hospitalar, pareado por sexo e idade (± 5 anos) com a coleta de dados realizada entre julho de 2006 e junho de 2008. A amostra foi composta por 296 pacientes com câncer de boca e orofaringe e 296 pacientes sem histórico de câncer atendidos em quatro hospitais da cidade de São Paulo (SP), Brasil. Foi aplicado um questionário semiestruturado, para a coleta de dados relativos à condição socioeconômica e aos hábitos deletérios (tabaco e bebidas alcoólicas). Para avaliação do consumo alimentar, utilizou-se um questionário de frequência alimentar qualitativo. A análise se deu por meio de modelos de regressão logística multivariada, que consideraram a hierarquia existente entre as características estudadas. RESULTADOS: Entre os alimentos de origem animal, o consumo frequente de carne bovina (OR = 2,73; IC95% = 1,27-5,87; P < 0,001), bacon (OR = 2,48; IC95% = 1,30-4,74; P < 0,001) e ovos (OR = 3,04; IC95% = 1,51-6,15; P < 0,001) estava relacionado ao aumento no risco de câncer de boca e orofaringe, tanto na análise univariada quanto na multivariada. Entre os laticínios, o leite apresentou efeito protetor contra a doença (OR = 0,41; IC95% = 0,21-0,82; P < 0,001). CONCLUSÕES: O presente estudo sustenta a hipótese de que alimentos de origem animal podem estar relacionados à etiologia do câncer de boca e orofaringe. Essa informação pode orientar políticas preventivas contra a doença, gerando benefícios para a saúde pública.

Sleep disorders in climacteric women

Introduction: This paper examines the various factors that contribute to the occurrence of sleep alterations during peri and post climacteric and thus produce significant imperil to women's quality of life. Among the probable causes of insomnia or sleep disorders associated to climacteric stand out the occurrence of vasomotor symptoms, depressive state and respiratory distress during sleep, such as sleep apnea, along with chronic pain, although psychosocial factors related to the climacteric bear major influence on such clinical status. Method: The bibliographic analysis was carried out using several electronic data base namely: Cochrane, Medline, Embase, Bni Plus, Biological Abstracts, Psycinfo, Web Of Science, Sigle, Dissertation Abstracts and ZETOC published in English, Spanish and Poruguese. The key terms used were: sleep, REM sleep, slow wave sleep polysomnography; electroencephalogram; sleep disturbances; disturbances of sleep onset and maintenance; excessive somnolence disturbances; climacteric; menopause; depression; neurobiology; biologic models; circadian rhythm; mental health and epidemiology. Case studies and letters to the editor were excluded. The summaries of the identified studies found in the data base were analyzed and assessed, and the data analyzed separately according to the subjective or objective criteria for data collection. Results: The climacteric transition constitutes a period of major risk for the development of depressive, vasomotor and insomnia symptoms although not caused solely by hypoestrogenism. The diagnostic methods used in the study of sleep disorders range from subjective assessment by means of response to specific questionnaires to the objective analysis of actigraphic or polissonographic daytime and nocturnal reports. Polissonographic studies of the whole night, performed at the laboratory, are the golden method of choice for diagnostic of sleep disorders. Studies point to the high prevalence of sleep disorders in the climacteric, especially insomnia, apnea and periodic movement of legs and also to the fact that this phase of life presents decrease in the quality of sleep. Women in peri and post climacteric show higher sleep latency and difficulty in its maintenance and refer being less satisfied with its quality even when compared to those who are not climacteric. Exception made to the vasomotor symptomatology, the other climacteric complaints such as mood disturbances, libido alterations, cognitive deficit, articular pain and sleep disorders are markedly associated to psychosocial factors, lifestyle and especially to women's perception of what the climacteric means to their lives. Conclusion: The analysis of the available studies revealed a proneness to deterioration of quality of life of climacteric women markedly in the sleep disturbances, depressed mood and anxiety domains and should not to be basically attributed to the climacteric. It is necessary that the professionals consider the need of assessment of such pathologies as complex phenomena and the literature lacks studies contemplating such dimensions.

The role of the experience and expression of anger in future cardiovascular profiles in young adolescents

Cardiovascular disease (CVD) is this nation's leading source of morbidity and mortality, with health disparities evident. Despite inconsistencies in the literature, there is a growing body of evidence that links anger and CV reactivity (CVR) to future CVD. Because CVD is a life-long process with beginnings in childhood, and because adolescents experience and express anger frequently, the need to understand the role that anger has in future CV profiles is important. If identifiable patterns are found, nursing interventions can be implemented at the most beneficial point in the lifespan. This study examined data collected as part of The Heartfelt Study (N = 374), which investigated anger in relation to 24-hour ambulatory blood pressure (BP) and CVR in a multi-ethnic (African, Hispanic, and European American) sample of adolescents (Time 1). This investigator conducted a follow-up for all The Heartfelt Study participants, 11 to 13 years old at the beginning of study, still in attendance at the middle school (N = 44) one year later (Time 2) to determine: (1) changes in anger over time were associated with changes in ambulatory CV profiles: systolic (SBP), diastolic (DBP), heart rate (HR), and pulse pressure (PP) over time; and (2) the extent to which CVR, initiated by talking about a recent anger-producing event, related to future ambulatory CV profiles. A mixed-effects regression for repeated measures was used to analyze the data and found that SBP reactivity at Time 1 was significantly (β = 0.2341, t = 5.91, p < 0.0001) associated with ambulatory SBP at Time 2 and PP reactivity at Time 1 was significantly (β = 0.1530, t = 5.70, p < 0.0001) associated with ambulatory PP at Time 2. Changes in anger over time were not associated with changes in ambulatory BP measures over time. Further research on anger and CVR among adolescents over longer periods of time is recommended. ^

Competencias y contenidos comunes de salud pública en los programas universitarios de grado: fisioterapia, terapia ocupacional, ciencias ambientales, odontología y veterinaria

Objetivo: Identificar competencias y contenidos básicos de salud pública para los programas de grado en fisioterapia, terapia ocupacional, ciencias ambientales, odontología y veterinaria, desde la perspectiva del profesorado de diversas universidades españolas. Método: En el contexto del II taller sobre contenidos de salud pública en los programas de grado (Mahón, 19-20 de septiembre de 2012), se organizaron cinco grupos de trabajo formados por 20 profesores/as de distintas universidades españolas, seleccionados de las guías docentes de salud pública y epidemiología publicadas en la página web de la Conferencia de Rectores de Universidades Españolas. Cada grupo trabajó sobre un grado y los resultados se discutieron en sesiones plenarias. Resultados: Para todas las titulaciones se identificaron actividades y competencias para las tres funciones esenciales de la salud pública. La mayoría de las competencias profesionales identificadas en cada uno de los grados correspondieron a la función «Valorar las necesidades de salud de la población». Los grupos de trabajo propusieron contenidos de epidemiología, introducción y conceptos de salud pública, intervención en salud pública, gestión sanitaria y políticas en salud. Las principales coincidencias en los contenidos de las titulaciones se dieron en los tres primeros. Conclusiones: Se han identificado competencias y contenidos de salud pública comunes a los distintos grados estudiados que pueden servir de punto de partida para iniciar una revisión más detallada de los programas de salud pública en los diferentes grados, y alcanzar un consenso sobre los contenidos comunes que debería incluir cada uno de ellos

Desigualdades de género en la investigación en salud pública y epidemiología en España (2007-2014)

Objetivo: Analizar las desigualdades de género en investigación en salud pública y epidemiología en España, en el periodo 2007-2014. Método: Estudio descriptivo según sexo de posiciones de liderazgo del Centro de Investigación Biomédica en Red (CIBER), especialmente en el área temática de epidemiología y salud pública (CIBERESP) en 2014; de sociedades científicas de salud pública (SESPAS) y epidemiología (SEE), 2009-2014; y de proyectos de investigación solicitados (13.320) y financiados (4699), e importes de convocatorias de Acción Estratégica en Salud (AES), 2007-2013. Resultados: Existe una clara infrarrepresentación de mujeres líderes y contratadas en investigación de excelencia en salud pública (CIBERESP), con predominio de los hombres en puestos de decisión. Aunque los proyectos de investigación de la Acción Estratégica en Salud (AES) liderados por mujeres han crecido ligeramente entre 2007 y 2013, entre los solicitados no alcanzan el 50%, con excepción de los de la Comisión de Salud Pública. La brecha de género es aún mayor en proyectos financiados. Los proyectos liderados por hombres tienen mayor probabilidad de obtener financiación, alcanzando el 29% en los de salud pública. Persiste una segregación horizontal de género en posiciones de reconocimiento científico en congresos de SESPAS y SEE. Conclusiones: La sobrerrepresentación de líderes masculinos en la investigación en salud pública en España debe entenderse como indicador y consecuencia del androcentrismo en las sociedades científicas y los grupos profesionales. Esta situación sexista pone en riesgo la existencia de productos y servicios innovadores desde la perspectiva de género que den respuestas a necesidades y demandas de toda la sociedad. Se necesitan más mujeres en investigación que tengan incorporada esta perspectiva.
