Efeitos da automonitoração sobre o comportamento de adesão a dois tipos de regras nutricionais em adultos com diabetes tipo 2

O diabetes mellitus é uma doença crônica de etiologia múltipla, cujo tratamento inclui mudanças no estilo de vida, onde a adoção de hábitos alimentares saudáveis é de suma importância para o controle da doença. No entanto, a adesão ao plano alimentar é um dos aspectos de maior desafio para o tratamento desta patologia. Esta pesquisa teve como objetivo comparar a eficácia do uso de procedimentos de automonitoração sobre o comportamento de adesão a dois tipos de regras nutricionais (Plano Alimentar – PA e Contagem Total de Carboidratos - CTC) em adultos com diabetes Tipo 2. Participaram quatro adultos inscritos no Programa HiperDia de uma Unidade Municipal de Saúde, na cidade de Belém, apresentando dificuldades de adesão à dieta. A coleta de dados aconteceu no laboratório de Patologia da Nutrição e em ambiente domiciliar dos participantes. O procedimento constou de: (1) Composição da amostra e entrevista para confirmação dos critérios de inclusão; (2) Caracterização da linha de base (LB) do comportamento alimentar; (3) Intervenção: Treino de Automonitoração (AM) com PA para dois participantes da Condição A (CTa) e com CTC para dois participantes da Condição B (CTb); (4) Reversão das condições de Treino; (5) Follow-up e (6) Entrevista Final. O Treino em AM incluiu a verificação da correspondência entre o registro do comportamento alimentar e as regras nutricionais; a análise dos custos e benefícios da emissão dos comportamentos de seguimento das regras estabelecidas; análises funcionais da emissão ou não do comportamento de seguir as regras e o planejamento das ações de adesão. O participante foi solicitado a registrar todas as refeições realizadas em intervalos de dois em dois dias a cada visita domiciliar da pesquisadora. Calculou-se o Índice de Adesão à Dieta (IAD) por dia de registro. Nos resultados, observou-se que, na linha de base os IADs de todos os participantes estavam abaixo de 50%. No entanto, após o Treino em AM, a média dos IADs obtidos pelos participantes quando submetidos ao PA foi igual a 62,49%, enquanto a obtida em CTC foi de 75,50%. Os valores absolutos dos IADs encontrados nos participantes da CTa foram maiores do que os IADs dos participantes da CTb. Todos os participantes, independente da condição, apresentaram aumento nos IADs ao serem comparados com a LB, com declínio após a suspensão da AM. Ao término da AM, dois participantes escolheram PA e dois a CTC para seguir o tratamento; entretanto, observou-se que todos mantiveram o seguimento do PA no follow-up. Inferiu-se que a CTC parece ser mais eficaz em instalar comportamentos alimentares adequados e o PA parece obter bons resultados na manutenção dos comportamentos instalados. Todos os participantes se encontravam com excesso de peso na LB, dois participantes reduziram o peso após a intervenção, mas todos mantiveram o diagnóstico nutricional da LB. Quanto à hemoglobina glicada, todos os participantes apresentavam valores acima de 6% durante a LB e, após a intervenção, três participantes reduziram esse valor. Discute-se a importância de nutricionistas auxiliarem o paciente a ficar sob o controle das mudanças observadas em seu repertório por meio da análise de contingências, prescrevendo um tratamento individualizado e para além do foco na doença.

Leprosy: a review of laboratory and therapeutic aspects - Part 2

Leprosy is a chronic infectious condition caused by Mycobacterium leprae(M. leprae). It is endemic in many regions of the world and a public health problem in Brazil. Additionally, it presents a wide spectrum of clinical manifestations, which are dependent on the interaction between M. leprae and host, and are related to the degree of immunity to the bacillus. The diagnosis of this disease is a clinical one. However, in some situations laboratory exams are necessary to confirm the diagnosis of leprosy or classify its clinical form. This article aims to update dermatologists on leprosy, through a review of complementary laboratory techniques that can be employed for the diagnosis of leprosy, including Mitsuda intradermal reaction, skin smear microscopy, histopathology, serology, immunohistochemistry, polymerase chain reaction, imaging tests, electromyography, and blood tests. It also aims to explain standard multidrug therapy regimens, the treatment of reactions and resistant cases, immunotherapy with bacillus Calmette-Guérin (BCG) vaccine and chemoprophylaxis.

Analysis of cardiopulmonary and metabolic variables measured during laboratory and sport-specific incremental tests for table tennis performance prediction

Purpose. - The purposes of this study were: i) to compare the physiological responses measured during a specific table tennis incremental test with the physiological responses measured during cycling, arm cranking, and treadmill running tests; and ii) to verify the accuracy of table tennis performance prediction based on the physiological responses from these tests.Methods. - Eleven national level male table tennis players participated in the study and undertook incremental tests using ergometers. Table tennis performance was defined as the ranking obtained during a simulated tournament between the participants.Results. - In general, peak values for physiological variables (e.g., (V) over dotO(2PEAK) and [La]PEAK) were significantly lower (P < 0.05) in the specific test (e.g., (V) over dotO(2PEAK) = 39.9 +/- 1.5 ml.kg(-1) per minute and [La]PEAK = 6.4 +/- 0.5 mmol.L-1) than during cycling (e.g., (V) over dotO(2PEAK) = 41.3 +/- 1.4 ml.kg(-1) per minute and [La]PEAK = 10.2 +/- 0.7 mmol.L-1) or running (e.g., (V) over dotO(2PEAK) = 43.9 +/- 1.5 ml.kg(-1) per minute and [La]PEAK = 10.0 +/- 0.7 mmol.L-1), but higher than during arm cranking (e.g., (V) over dotO(2PEAK) = 26.6 +/- 1.6 ml.kg(-1) per minute and [La]PEAK = 8.9 +/- 0.6 mmol.L-1). At respiratory compensation point intensity (RCP), only the variables measured on arm cranking were lower (P < 0.05) than on the other ergometers. Stepwise multiple regression analysis showed significant correlation between table tennis performance and lactate concentration ([La]) and also rate of perceived effort (RPE) at RCP during cycling (r = 0.89; P < 0.05).Conclusion. - In conclusion, the significant differences obtained between the specific and laboratory ergometers demonstrate the need to use a specific test to measure physiological parameters in table tennis and the physiological parameters measured, independent of the ergometer used, are unable to predict table tennis performance.

JUVENILE DEVELOPMENT OF DILOCARCINUS PAGEI STIMPSON, 1861 (BRACHYURA, TRICHODACTYLIDAE) REARED IN THE LABORATORY, WITH EMPHASIS ON SETAE MORPHOLOGY

The juvenile development of the freshwater crab Dilocarcinus pagei Stimpson, 1861 was studied under laboratory conditions, focusing on setae morphology. The ovigerous females were collected manually associated with water hyacinth at the Municipal Dam of Sao Jose do Rio Preto (Sao Paulo, Brazil). The specimens were raised in the laboratory under constant aeration, photoperiod (12: 12 h) and temperature (27 +/- 1 degrees C). Twelve juvenile stages were obtained with descriptions of the main morphological characters that allow their identification are presented. Fourteen types of setae were discovered: dentate, denticulate, serrulate, papposerrate, cuspidate, plumose, plumodenticulate, plumoserrulate, simple, pappose, brush, curved, nail and setules. The greatest diversity of setae was found on the mouth appendages, especially the maxillule. The gill ontogeny and sexual dimorphism becomes apparent from the second juvenile stage onwards. At the third juvenile stage, the carapace begins to exhibit a wider shape, becoming similar to that of the adults.

A laboratory evaluation of alcohols as attractants for the sandfly Lutzomyia longipalpis (Diptera: Psychodidae)

Background: The potential attraction from 1-octen-3-ol for sandflies has been documented; however, studies using other primary alcohols are limited.Findings: We used a wind tunnel to compare the activation and attractive behaviors in male and female Lutzomyia longipalpis using 1-octen-3-ol and three additional alcohols, 1-octanol, 1-heptanol and 1-nonanol at three different concentrations: neat (100%) and diluted in hexane (10% and 50%). The compounds 1-octen-3-ol and 1-nonanol induced a clear concentration-dependent activation and attraction response in females. In males, 1-octen-3-ol, 1-nonanol and 1-heptanol yielded the same results.Conclusions: L. longipalpis is attracted to 1-octen-3-ol, 1-nonanol and 1-heptanol, which are found in many plant volatiles.

Comparison of Nonmesonic Hypernuclear Decay Rates Computed in Laboratory and Center-of-Mass Coordinates

In this work we compute the one-nucleon-induced nonmesonic hypernuclear decay rates of He-5(Lambda), C-12(Lambda) and C-13(Lambda) using a formalism based on the independent particle shell model in terms of laboratory coordinates. To ascertain the correctness and precision of the method, these results are compared with those obtained using a formalism in terms of center-of-mass coordinates, which has been previously reported in the literature. The formalism in terms of laboratory coordinates will be useful in the shell-model approach to two-nucleon-induced transitions.

Laboratory testes with quality data in Dentistry

In laboratory tests, just following the manufacturer’s instructions of materials or equipments may not be enough to obtain reliable data. Thus, intra and inter-examiners studies may be required. The aim of this study was to illustrate the application of the Intraclass Correlation Coefficient (r) in a study related to the color changing and hardness of composite resin conducted by two examiners. The color and hardness of 10 specimens of composite resin were evaluated by a colorimetric spectrophotometer and hardness tester, respectively, at two different times. Two trained examiners performed two measurements with an interval of one week. Specimens were stored in artificial saliva at 37±1ºC for 7 days. The Intraclass Correlation was used for analysis of intra and inter-examiner reproducibility. The intra-examiner reproducibility was 0.79, 0.44 and 0.76 for L, a and b color coordinates for the examiner 1 and 0.84, 0.23, 0.21 for examiner 2. For hardness, r-values were 0.00 and 0.23 for the examiner 1 and 2, respectively, showing unsatisfactory agreement on color and hardness evaluation for both examiners. It was noted that only the observation of protocol for use of equipment and examiners training were not sufficient to collect reliable information. Thus, adjustments in the experimental protocol were made and devices were produced to standardize the measurements. The reproducibility study was performed again. For examiner 1, values as 0.90, 0.59 and 0.79 were verified for L, a and b coordinates and, for examiner 2 were obtained values of 0.90, 0.75, 0.95. In relation to hardness, r-values of 0.75 and 0.71 were obtained for examiners 1 and 2, respectively. The inter-examiner reproducibility was 0.86, 0.87, 0.91 for L, a and b coordinates and 0.79 for hardness. It was concluded that intra and inter-examiner calibration is essential for obtaining quality measurements in laboratory tests.
