ABSTRACT

OBJECTIVE: To systematically review the effects (benefits and harms) of different types of physical exercise on insomnia outcomes in adult populations with no mood disorders. Objective and subjective sleep outcomes and related mismatches were analyzed. METHODS: Systematic review and meta-analysis. Quality of evidence was also examined. RESULTS: Six studies including 295 participants with insomnia diagnosis were selected. Yoga, Tai Chi, resistance exercise and aerobic exercise were used in protocols with different duration, intensity and frequency. Studies involved different populations, including inactive or sedentary individuals, older adults and postmenopausal women. Physical exercise improved subjective sleep quality (very low quality of evidence) and reduced insomnia severity (high quality of evidence). CONCLUSION: Findings suggest individualized physical exercise must be addressed to design optimal protocols, with standardized type, duration, intensity, and frequency. For the time being, physical exercise may be considered an alternative and/or ancillary therapeutic modality for patients diagnosed with insomnia. Physical exercise can be used to improve subjective complaints, but not objective sleep outcomes.

ABSTRACT

Understanding the motives influencing food intake is indispensable for effective dietary recommendations aimed at promoting healthy eating in an integrative way. The objective of this study was to evaluate food choice motives across two socioeconomically different cities in Brazil. A cross-sectional study with a convenience sample (n = 473) of adults living in both places was evaluated. Food choice motives were assessed by The Eating Motivation Survey (TEMS) with 15 dimensions, and economic classifications were made according to the Brazilian Economic Classification Criteria (CCEB). Data analysis used both a general linear model (GLM) and a Structural Equation Model (SEM) adjusted for age, ethnicity, income and educational degree. Participants were mainly women (74.6%) with a mean age of 36.6 years. Cities were not invariant (Δχ2 = 314.165, p < 0.001) and two distinct prediction models for food choice motives emerged. Fit indices indicate acceptable model fit for both low (CFI = 0.911; TLI = 0.898; RMSEA = 0.041) and high socioeconomic status groups (CFI = 0.808; TLI = 0.717; RMSEA = 0.081). Although cities differ in the prediction models for food choice motives, we demonstrated that there are two main networks of predictors: one related to social context predictors of food choice motives and another related to hedonic-oriented ones. Particularly, hedonic-oriented motives (i.e., pleasure) were the most relevant predictors to the group of high socioeconomic status followed by social context predictors (traditional eating and sociability). On the other hand, the group of low socioeconomic status had most of its predictors related to social context (i.e., visual appeal, traditional eating, sociability, social norms and social image) and also price, but this last one was the least important among the most important predictors.

ABSTRACT

OBJECTIVE:: To determine the prevalence of alpha 1-antitrypsin (AAT) deficiency (AATD), as well as allele frequency, in COPD patients in Brazil. METHODS:: This was a cross-sectional study involving 926 COPD patients 40 years of age or older, from five Brazilian states. All patients underwent determination of AAT levels in dried blood spot (DBS) samples by nephelometry. Those with DBS AAT levels ≤ 2.64 mg/dL underwent determination of serum AAT levels. Those with serum AAT levels of < 113 mg/dL underwent genotyping. In case of conflicting results, SERPINA1 gene sequencing was performed. RESULTS:: Of the 926 COPD patients studied, 85 had DBS AAT levels ≤ 2.64 mg/dL, and 24 (2.6% of the study sample) had serum AAT levels of < 113 mg/dL. Genotype distribution in this subset of 24 patients was as follows: PI*MS, in 3 (12.5%); PI*MZ, in 13 (54.2%); PI*SZ, in 1 (4.2%); PI*SS, in 1 (4.2%); and PI*ZZ, in 6 (25.0%). In the sample as a whole, the overall prevalence of AATD was 2.8% and the prevalence of the PI*ZZ genotype (severe AATD) was 0.8. CONCLUSIONS:: The prevalence of AATD in COPD patients in Brazil is similar to that found in most countries and reinforces the recommendation that AAT levels be measured in all COPD patients. OBJETIVO:: Determinar a prevalência da deficiência de alfa 1-antitripsina (AAT), bem como a frequência alélica, em pacientes com DPOC no Brasil. MÉTODOS:: Estudo transversal com 926 pacientes com DPOC, com 40 anos ou mais, oriundos de cinco estados brasileiros. Todos os pacientes foram submetidos a dosagem de AAT em amostras de sangue seco por meio de nefelometria. Aqueles em que a concentração de AAT no sangue seco foi ≤ 2,64 mg/dl foram submetidos a dosagem sérica de AAT. Aqueles em que a concentração sérica de AAT foi < 113 mg/dl foram submetidos a genotipagem. Quando os resultados foram discrepantes, foi realizado o sequenciamento do gene SERPINA1. Dos 926 pacientes com DPOC estudados, 85 apresentaram concentração de AAT em sangue seco ≤ 2,64 mg/dl, e 24 (2,6% da amostra) apresentaram concentração sérica de AAT < 113 mg/dl. A distribuição genotípica nesse subgrupo de 24 pacientes foi a seguinte: PI*MS, em 3 (12,5%); PI*MZ, em 13 (54,2%); PI*SZ, em 1 (4,2%); PI*SS, em 1 (4,2%); e PI*ZZ, em 6 (25,0%). Na amostra estudada, a prevalência global da deficiência de AAT foi de 2,8% e a prevalência do genótipo PI*ZZ (deficiência grave de AAT) foi de 0,8%. CONCLUSÕES:: A prevalência da deficiência de AAT em pacientes com DPOC no Brasil é semelhante àquela encontrada na maioria dos países e reforça a recomendação de que se deve medir a concentração de AAT em todos pacientes com DPOC.

ABSTRACT

OBJECTIVE: To validate and develop an immunonephelometric assay for the determination of alpha-1 antitrypsin (AAT) levels in dried blood spots from COPD patients in Brazil. METHODS: We determined AAT levels in serum samples and dried blood spots from 192 COPD patients. For the preparation of dried blood spots, a disk (diameter, 6 mm) was placed into a tube, eluted with 200 µL of PBS, and stored overnight at 4ºC. All of the samples were analyzed by immunonephelometry in duplicate. We used the bootstrap resampling method in order to determine a cut-off point for AAT levels in dried blood spots. RESULTS: The correlation coefficient between the AAT levels in serum samples and those in dried blood spots was r = 0.45. For dried blood spots, the cut-off value was 2.02 mg/dL (97% CI: 1.45-2.64 mg/dL), with a sensitivity, specificity, positive predictive value, and negative predictive value of 100%, 95.7%, 27.2%, and 100%, respectively. CONCLUSIONS: This method for the determination of AAT levels in dried blood spots appears to be a reliable screening tool for patients with AAT deficiency.

OBJETIVO: Validar e desenvolver um método de dosagem de alfa-1 antitripsina (AAT) por imunonefelometria em amostras de sangue em papel-filtro em pacientes com DPOC no Brasil. MÉTODOS: Amostras de soro e de sangue em papel-filtro de 192 pacientes com DPOC foram utilizadas para a dosagem de AAT. Para a preparação das amostras de sangue em papel-filtro, um disco do papel com diâmetro de 6 mm foi colocado em um tubo e eluído com 200 µL de PBS, permanecendo por toda a noite a 4ºC. Todas as amostras foram analisadas em duplicata por imunonefelometria. O método de reamostragem bootstrap foi utilizado para a determinação de um ponto de corte para o nível de AAT nas amostras de sangue em papel-filtro. RESULTADOS: O coeficiente de correlação entre os níveis de AAT em soro e em sangue em papel-filtro foi de r = 0,45. Para as amostras em papel-filtro, o ponto de corte foi de 2,02 mg/dL (IC97%: 1,45-2,64 mg/dL), com sensibilidade, especificidade, valor preditivo positivo e valor preditivo negativo de 100%, 95,7%, 27,2% e 100%, respectivamente. CONCLUSÕES: Este método de determinação dos níveis de AAT em sangue em papel-filtro se mostrou uma ferramenta confiável para o rastreamento de pacientes com deficiência de AAT. .

ABSTRACT

The present study aimed to translate the Parent Mealtime Action Scale (PMAS) into Portuguese and to evaluate the factorial structure and the psychometric characteristics of this version. Further, we investigated the associations between parent mealtime actions and the intake of fruits, vegetables and energy-dense foods in 6-10years-old children from São Paulo city, Brazil, controlling for potential confounding variables. A total of 582 parents (86% mothers) answered questions regarding their mealtime actions, their children's food intake, the characteristics of the family meals and their socioeconomic conditions. Factorial analyses grouped all of the 31 questions in the same factors as the original scale, except one item that was transferred to another dimension. Internal reliability and reproducibility analyses obtained satisfactory results. Children who ate fruits and vegetables more frequently had parents who often ate these foods and made them available; these parents also seldom offered their children special meals. Children who more often consumed energy-dense foods had parents who frequently ate this type of food and rarely set limits on its intake. The Portuguese version of the PMAS may be a good tool for evaluating the influence of parent mealtime actions on Brazilian children's food intake.

ABSTRACT

Early life stress is a strong predictor of future psychopathology during adulthood. The Early Trauma Inventory (ETI) was developed to detect the presence and impact of traumatic experiences that occurred up to 18 years of age. The ETI was translated and cross-culturally adapted and had its consistency evaluated. Victims of violence that met the inclusion and exclusion criteria were submitted to SCID-I and ETI. Ninety-one patients with post-traumatic stress disorder (PTSD) were included. Cronbach's alpha in the different domains varied from 0.595 to 0.793, and the total score was 0.878. Except for emotional abuse, most of the various domains displayed inter-item correlation rates of 0.51 to 0.99. The adapted version was useful for clinical and research purposes and showed good internal consistency and inter-item correlation. The ETI is a valid instrument with good consistency for evaluating history of childhood and adolescent trauma in adults.

ABSTRACT

As experiências traumáticas precoces são um fator de risco preditivo de problemas psicopatológicos futuros. O Early Trauma Inventory (ETI) é um instrumento que avalia em indivíduos adultos experiências traumáticas ocorridas antes dos 18 anos de idade. Tal instrumento foi traduzido, transculturalmente adaptado e sua consistência interna foi avaliada. Vítimas de violência que preencheram os critérios de inclusão e exclusão foram submetidas a uma entrevista diagnóstica (SCID-I) e ao ETI. Foram incluídos 91 pacientes com o transtorno do estresse pós-traumático (TEPT). O alfa de Cronbach nos diferentes domínios variou de 0,595-0,793, e o escore total foi de 0,878. A maior parte dos itens nos vários domínios, com exceção do abuso emocional, apresentou índices de correlação interitem entre 0,51-0,99. A versão adaptada foi útil tanto na clínica quanto na pesquisa. Apresentou boa consistência interna e na correlação interitem. O ETI é um instrumento válido, com boa consistência para se avaliar a presença de história de traumas precoces em indivíduos adultos.

ABSTRACT

O presente trabalho tem por objetivo verificar a influencia de atributos físicos na tomada de decisões sob condições de incerteza. O uso de barba tem uma importância dentro da história evolutiva da espécie humana, tendo um possível valor adaptativo desse traço no ambiente ancestral, moldado por seleção intra ou intersexual. Já a cor de pele pode ser um subproduto de coalizões que representam o modelo mental presente na história evolutiva do homem, assim como o uso de barba. Esta tese é composta de quatro estudos. O primeiro estudo retomou a pesquisa de Freedman (1969). Trata-se da parte relativa à aplicação da prancha IV, V e VII do Teste de Apercepção Temática (TAT) em que um grupo de controle (n=356) vê a prancha original, apresentando um homem idoso com semblante sério, perto de um homem jovem, com o rosto barbeado, também com o semblante sério (VII) ou uma mulher jovem ao lado de um homem jovem (prancha V) ou ainda uma mulher idosa de costas para um homem jovem (IV). O grupo experimental (n= 347) vê as mesmas pranchas, mas com uma barba desenhada no rosto do homem mais jovem em cada uma delas. No segundo Estudo, 1014 estudantes universitários avaliaram cada uma das pranchas com base em escalas de diferencial semântico utilizando um grupo de 26 atributos propostos por Muscarella (1990), divididos em cinco fatores. No Estudo I encontramos associações significantes entre a presença de barba e um maior status e percepção de dominância em relação aos modelos sem barba. Além disso, encontramos que a presença de agressividade nas histórias do TAT é associada com a diferença de status entre os personagens da prancha. No estudo II encontramos escores mais altos de atributos ligados a neotenia nas pranchas com o modelo jovem sem barba em relação aos modelos com barba. A presença de barba tende a aumentar a percepção de traços associados com masculinidade, (...)


... dominância, agressividade, força e autoconfiança. A partir desta hipótese esperávamos que homens exibindo atributos físicos associados com masculinidade, maturidade, dominância e status fossem avaliados como mais atraentes pelas mulheres, o que não ocorreu, dando suporte a hipótese de seleção intrasexual da barba. O Estudo III e IV mostra a influência da presença de barba e da cor de pele no processo decisório de funcionários e gerentes da área de Recursos Humanos. Encontramos que profissionais sem barba têm maior chance no mundo dos negócios brasileiro, sobretudo em profissões corporativas (Gerente Financeiro), devido a sua aparência menos intimidadora. Por outro lado, candidatos com barba foram preferidos em ocupações ditas "liberais" (Web Designer), onde características não conformistas e de maior dominância são mais comuns. Em relação à cor de pele, não foi encontrada nenhum tipo de preferência ou associação diferencial significante. É importante lembrar que, a longo prazo, o sucesso de uma pessoa é um fenômeno complexo multifatorial, mas não se descarta a relevância das primeiras impressões no processo decisório, através de representações sociais estereotipadas

ABSTRACT

0 objetivo da dissertação foi investigar a influência da barba na formação de primeiras impressões tendo por referencial teórico a perspectiva Evolucionista e o possível valor adaptativo deste traço no ambiente ancestral, moldado por seleção intra ou inter-sexual. O presente trabalho é composto de quatro estudos. Examinou-se o impacto de quatro tipos de pilosidade na percepção de homens adultos por 116 estudantes universitários de ambos os sexos, em relação a 12 qualidades pessoais (Estudo 1) e na ótica de 16 empregadores de sexo masculino, indicando potencial influência sobre decisões de contratação para diferentes papéis (Estudo 2). No terceiro estudo, retomou-se uma parte da pesquisa de Freedman (1969). Trata-se da parte relativa à aplicação da prancha VII do Teste de Apercepção Temática (TAT) em que um grupo de controle vê a prancha original, apresentando um homem idoso com semblante sério, perto de um homem jovem, com o rosto barbeado, também com o semblante sério. O grupo experimental vê a mesma prancha, mas com uma barba desenhada no rosto do homem mais jovem. Por fim, no Quarto Estudo, a partir da análise de conteúdo feita das entrevistas, foram elaboradas escalas de diferencial semântico utilizando os atributos mais significativos como âncoras, podendo-se assim estabelecer uma discussão entre os dados encontrados, a pesquisa de Freedman e as referências base deste estudo. No Estudo 1, encontramos que a presença de barba aumenta a percepção de idade em torno de 3,6 anos. A presença de barba tende a aumentar a percepção de traços associados com masculinidade, dominância, agressividade, força e autoconfiança. A partir desta hipótese esperávamos que homens exibindo atributos fisicos associados com masculinidade, maturidade, dominância e status fossem avaliados como...(AU)
