ABSTRACT

Resumo Objetivo Compreender a percepção do acesso e da qualidade da alimentação para a população em situação de rua. Métodos Estudo descritivo qualitativo, realizado em um Centro de Referência da População de Rua na região centro-sul de Belo Horizonte (MG). Utilizou-se roteiro semiestruturado para a realização das entrevistas de 18 participantes. A coleta de dados ocorreu entre dezembro de 2020 e janeiro de 2021. A análise temática do material, proposta por Bardin, possibilitou a elaboração de três categorias empíricas. Resultados O público entrevistado era masculino, com idade média de 43 anos e tempo médio de situação de rua de 44,6 meses. O acesso à alimentação foi proveniente das doações de alimentos, refeições em instituições governamentais e aquisições ao dispor de renda. Foram relatadas dificuldades quanto à quantidade e qualidade dos alimentos, à aquisição das refeições nos fins de semana, aos sentimentos de medo e angústia perante a fome, à falta do alimento e pelo estigma social, agravados pela COVID-19. Conclusão Diante do cenário de iniquidades sociais, o direito ao acesso à alimentação não é garantido, sendo necessária a implementação de políticas públicas de proteção social que garantam os direitos básicos.

Abstract Objective To understand the perception of access to food and food quality for the street population. Methods This qualitative descriptive study was performed in a Reference Center for the Homeless Population in the south-central region of Belo Horizonte (MG). A semi-structured script was used to conduct interviews with 18 participants. Data collection occurred between December 2020 and January 2021. The thematic analysis of the material, as proposed by Bardin, made it possible to elaborate three empirical categories. Results The public interviewed was male, with a mean age of 43 years, and a mean time on the streets of 44.6 months. Access to food came from donations, meals at government institutions, and acquisition when income was available. Difficulties were reported regarding the quantity and quality of food, acquisition of meals on weekends, feelings of fear and anguish in the face of hunger, lack of food, and social stigma, which were aggravated by COVID-19. Conclusion As in this scenario of social inequalities the access to food is not guaranteed, implementing public policies of social protection is necessary to guarantee basic rights.

ABSTRACT

Upper and lower limbs can be affected by several diseases and changes related to current life habits, such as the sedentarism, technological advances, and even eating habits. This cross-sectional study investigated morphological adaptations of the biceps brachii muscle and the performance of the elbow flexors in healthy individuals in the early phase of aging. Thirty-two volunteers were separated according to age range (3rd, 4th, and 5th decades of life) and sex. Smaller diameters and subtypes of fibers were evaluated using muscle biopsies, and peak torque and total work were assessed using an isokinetic dynamometer. The variables were compared considering sex and decade, using mixed-effects linear models. The smaller diameter of all fiber types did not differ significantly between age groups for either sex. The proportion of oxidative fibers was reduced in male participants in the 4th (-20%) and 5th (-6%) decades of life compared to the 3rd decade, and there was an increase in the number of oxidative fibers in women from the 4th (+14%) to the 5th decade of life. There were no significant changes in the peak torque and total work between the analyzed age groups. The early phase of aging starts with alterations in the proportion of fibers, with a decrease in oxidative fibers in men and an increase in oxidative fibers in women. Smaller diameter, torque, and total work did not change over these decades of life.

ABSTRACT

Abstract Introduction: The number of kidney transplants (KTx) is increasing in Brazil and, consequently, the costs of this procedure increase the country's health budget. We retrospectively evaluated the data of kidney transplant procedures until hospital discharge, according to kidney function recovery after the procedure. Methods: Retrospective analysis of the non-sensitized, 1st KTx from deceased donors performed between Jan/2010 to Dec/2017. Results: Out of the 1300 KTx from deceased donors performed in this period, 730 patients were studied and divided into 3 groups: Immediate Renal Function (IRF) - decrease in serum creatinine ≥ 10% on two consecutive days; Delayed Graft Function (DGF) - decrease in serum creatinine <10% on two consecutive days, without the need for dialysis, and Dialysis (D) - need for dialysis during the first week. Patients in group D stayed longer in the hospital compared to DGF and IRF (21, 11 and 8 days respectively, p < 0.001). More D patients (21%) were admitted to the ICU and performed a greater number of laboratory tests (p < 0.001) and renal biopsies (p < 0.001), in addition to receiving a higher amount of immunosuppressants. Total hospital costs were higher in group D and DGF compared to IRF (U$ 7.021,48; U$ 3.603,42 and U$ 2.642,37 respectively, p < 0.001). Conclusion: The costs of the transplant procedure is impacted by the recovery of kidney function after the transplant. The reimbursement for each of these different kidney function outcomes should be individualized in order to cover their real costs.


Resumo Introdução: O número de transplantes renais (KTx, do inglês kidney transplant) está aumentando no Brasil e, consequentemente, os custos deste procedimento aumentam o orçamento de saúde do país. Avaliamos retrospectivamente dados dos procedimentos de transplantes renais até a alta hospitalar, de acordo com a recuperação da função renal após o procedimento. Métodos: Análise retrospectiva dos 1º KTx de doadores falecidos, não sensibilizados, realizados entre Jan/2010 a Dez/2017. Resultados: Dos 1300 KTx de doadores falecidos realizados neste período, 730 pacientes foram estudados e divididos em 3 grupos: Função Renal Imediata (FRI) - diminuição na creatinina sérica ≥ 10% em dois dias consecutivos; Função Retardada do Enxerto (FRE) - diminuição na creatinina sérica <10% em dois dias consecutivos, sem necessidade de diálise, e Diálise (D) - necessidade de diálise durante a primeira semana. Pacientes no grupo D permaneceram mais tempo no hospital em comparação com FRE e FRI (21, 11 e 8 dias dias respectivamente, p < 0,001). Mais pacientes do grupo D (21%) foram admitidos na UTI e realizaram um maior número de testes laboratoriais (p < 0,001) e biópsias renais (p < 0,001), além de receberem uma quantidade maior de imunossupressores. Os custos hospitalares totais foram mais elevados nos grupos D e FRE em comparação com FRI (U$ 7.021,48; U$ 3.603,42 e U$ 2.642,37 respectivamente, p < 0,001). Conclusão: Os custos do procedimento de transplante são impactados pela recuperação da função renal após o transplante. O reembolso para cada um desses diferentes desfechos da função renal deve ser individualizado a fim de cobrir seus custos reais.

ABSTRACT

O entendimento do processo saúde-doença muda com o tempo histórico, tendo seguido uma tendência a cada vez mais patologizar fenômenos antes tidos como naturais, abrindo caminho para um cenário de valorização de excessos. Diante disso e da importância de proteger as pessoas dos possíveis danos causados pelas intervenções médicas, surgiu a prevenção quaternária (P4), que versa sobre uma medicina menos iatrogênica, evitando sobrediagnóstico, sobremedicalização e intervenções desnecessárias. Contudo, na prática clínica, médicos encontram diversos entraves para a sua aplicação, sendo comum não utilizá-la, mesmo se tendo consciência de sua importância. Dentre essas barreiras, destacam-se a dificuldade de negar uma demanda ao paciente e de lidar com situações de discordância, a pouca destreza argumentativa, e o medo de deixar de fazer um diagnóstico ou de perder a confiança da relação. O presente ensaio discute técnicas de habilidades de comunicação, à luz da medicina centrada na pessoa, com o objetivo de auxiliar médicos e médicas diante dessas dificuldades. Partindo de situações cotidianas, foram buscadas respostas em referências científicas, como livros, artigos e manuais. Algumas dessas técnicas apresentadas são: como negar uma demanda, entender o desejo pessoal por uma intervenção médica, lidar com a divergência de ideias, explorar a experiência da não-concordância, desprescrever medicações e compartilhar as decisões. Espera-se que, a partir desta leitura, os profissionais se sintam mais preparados e motivados para nadar contra a corrente hegemônica das intervenções médicas desnecessárias, contribuindo para que a medicina avance no sentido de promover o melhor cuidado possível às pessoas, sobretudo, primeiro não lhes causando mal.


The understanding of the health-disease process changes over time. Nowadays, it is heading towards an increase in pathologizing phenomena previously considered to be natural and paves the way for a scenario of valuing the excesses. Therefore the importance of protecting people from possible damage caused by medical interventions, quaternary prevention (P4) emerged, advocating for a less iatrogenic medicine, avoiding overdiagnosis, overmedicalization, and unnecessary interventions. However, in clinical practice, doctors face several obstacles at the application of P4, so they frequently not use it, even though they are aware of its importance. Among these obstacles, we highlight the difficulty of denying a patient's demand, dealing with situations of disagreement, poor argumentative skills, and the fear of not making a diagnosis or losing the patient's confidence. This essay discusses communication skills techniques, taking account the person-centered medicine, aiming to assist doctors in the face of these difficulties. Starting from everyday situations, answers were sought in scientific references, such as books, articles and manuals. Some of the techniques presented are: how to deny a demand, how to understand the personal desire for a medical intervention, how to deal with the divergence of ideas, how to explore the experience of non-agreement, how to undeprescribe medications, and how to do share decision making. It is expected that, after this reading, professionals may feel more prepared and motivated to swim against the hegemonic tide of unnecessary medical interventions. This could help medicine to follow the "first, do no harm" principle and advance in order to promote the best possible care for people.


La comprensión del proceso salud-enfermedad cambia con el tiempo histórico, al haber seguido una tendencia a patologizar cada vez más los fenómenos que antes se consideraban naturales, abriendo el camino para un escenario de valoración de los excesos. Ante esto y la importancia de proteger a las personas de posibles daños causados por intervenciones médicas, surgió la Prevención Cuaternaria (P4), que trata de una medicina menos iatrogénica, evitando el sobrediagnóstico, la sobremedicalización y las intervenciones innecesarias. Sin embargo, en la práctica clínica, los médicos encuentran varios obstáculos para la aplicación de la P4, y es común no usarla, aunque sean conscientes de su importancia. Entre estos obstáculos, destacamos la dificultad de negar una demanda al paciente y de lidiar con situaciones de desacuerdo, la poca destreza argumentativa y el miedo de no hacer un diagnóstico o perder la confianza del paciente. Este ensayo analiza las técnicas de habilidades de comunicación, a la luz de la Medicina Centrada en la Persona, con el objetivo de ayudar a los médicos frente a estas dificultades. A partir de situaciones cotidianas, se buscaron respuestas en referencias científicas, como libros, artículos, manuales. Algunas de estas técnicas presentadas son: cómo negar una demanda, comprender el deseo personal de una intervención médica, lidiar con la divergencia de ideas, explorar la experiencia de no estar de acuerdo, desprescribir medicamentos y compartir decisiones. Se espera que, a partir de esta lectura, los profesionales se sientan más preparados y motivados para nadar contra la corriente hegemónica de intervenciones médicas innecesarias - haciendo honor a la máxima "lo primero es no hacer daño" - y así contribuir a que la medicina avance para promover la mejor atención posible para las personas.

ABSTRACT

This study aimed to estimate genetic parameters for simulated data of body weight (BW), abdominal width (AW), abdominal length (AL), and oviposition. Simulation was performed based on real data collected at apiaries in the region of Campo das Vertentes, Minas Gerais, Brazil. Genetic evaluations were performed using single- and two-trait models and (co)variance components were estimated by the restricted maximum likelihood method. The heritability for BW, AW, AL and oviposition were 0.54, 0.47, 0.31 and 0.66, respectively. Positive genetic correlations of high magnitude were obtained between BW and AW (0.80), BW and oviposition (0.69), AW and oviposition (0.82), and AL and oviposition (0.96). The genetic correlations between BW and AL (0.11) and between AW and AL (0.26) were considered moderate and low. In contrast, the phenotypic correlations were positive and high between BW and AW (0.97), BW and AL (0.96), and AW and AL (0.98). Phenotypic correlations of low magnitude and close to zero were obtained for oviposition with AL (0.02), AW (-0.02), and BW (-0.03). New studies involving these characteristics should be conducted on populations with biological data in order to evaluate the impact of selection on traits of economic interest.(AU)


Objetivou-se estimar parâmetros genéticos para dados simulados de peso corporal (PC), largura abdominal (LA), comprimento abdominal (CA) e oviposição (OV). A simulação foi conduzida com base em dados reais, coletados em apiários da região do Campo das Vertentes, Minas Gerais. As estimativas das análises genéticas foram realizadas por modelos uni e bicaracterísticos, sendo os componentes de (co) variância estimados pelo método da máxima verossimilhança restrita. As herdabilidades para PC, LA, CA e OV foram de 0,54, 0,47, 0,31 e 0,66 respectivamente. As correlações genéticas foram positivas e de alta magnitude para PC e LA (0,80), PC e OV (0,69), LA e OV (0,82) e CA e OV (0,96). Para PC e CA (0,11) e LA e CA (0,26), as correlações genéticas foram moderadas e de baixa magnitude. As correlações fenotípicas foram positivas e de alta magnitude para PC e LA (0,97), PC e CA (0,96) e LA e CA (0,98). Para OV e CA (0,02), OV e LA (-0,02) e OV e PC (-0,03), foram encontradas correlações fenotípicas de magnitude baixa e próximas de zero. Novos estudos devem ser realizados em populações com dados biológicos, a fim de se observar o impacto da seleção em características de interesse econômico.(AU)

ABSTRACT

This study aimed to describe the main behaviors of white-lipped peccaries (Tayassu pecari) expressed in a semi-intensive production system in Brazil. The behavioral activities of two groups of peccaries allocated in two paddocks were assessed, totaling 17 adult animals and eventual pups in different developmental stages. The animals were visually observed using the ad libitum sampling and scan sample methods during the adaptation and experimental phases, respectively. The animals were evaluated in the morning, afternoon, and at night. The behavioral activities observed by ad libitum sampling comprised feeding, pool contact, moving, staying inside the handling area, resting, mud bathing, mutual rubbing, rubbing, aggression, sexual behavior, copulation, foraging, breastfeeding, sleeping, territorial marking, interactions, birthing, gnawing, and other behaviors. All behaviors observed by the ad libitum sampling method were confirmed in the experimental period by scan sample, except for territorial marking and birthing. The effects of time of day were statistically significant (p <0.05) for eating, pool contact, movement, staying inside the handling area, resting, mud bathing and sleeping. These results contribute to the understanding of instinctive animal habits and to the development of nutritional, environmental and health management protocols that meet the requirements of peccaries.(AU)


Objetivou-se descrever os principais comportamentos que os queixadas (Tayassu pecari) expressam em sistema de produção semi-intensivo no Brasil, bem como suas diferenças de frequências comportamentais em função do período do dia. Foram avaliadas as atividades comportamentais de dois grupos de queixadas alocados em dois piquetes, totalizando 17 animais adultos e eventuais filhotes em diferentes estágios comportamentais. Na fase adaptativa e experimental os animais foram observados visualmente pelos métodos ad libitum e scan sample, respectivamente. Os animais foram avaliados nos períodos da manhã, tarde e noite. As atividades comportamentais observadas pelo método ad libitum foram alimentação, contato com a piscina, movimentação, interior do brete de manejo, descanso, lameando, esfregação mútua, esfregar-se, agressão, comportamento sexual, cópula, fuçando, amamentação, dormindo, marcando território, interações, manilha, parição, roendo e outros comportamentos. Todos os comportamentos observados pelo método ad libitum foram confirmados no período experimental scan sample, exceto para as variáveis marcando território e parição. O efeito do período do dia foi estatisticamente significativo (P<0,05) sobre as frequências dos comportamentos alimentação, contato com a piscina, movimentação, interior do brete de manejo, descanso, lameando e dormindo. Os resultados contribuem para a compreensão dos hábitos instintivos dos animais e, com isso, colaborar com a elaboração de protocolos de manejo nutricional, ambiental e sanitário, buscando-se suprir as necessidades dos queixadas. Futuras pesquisas envolvendo queixadas em cativeiro fomentarão os estudos voltados aos aspectos biológicos, conservacionistas e produtivos.(AU)

ABSTRACT

SUMMARY BACKGROUND Analyze how the COVID-19 (SARS-CoV-2) pandemic and its social restriction measures affect sleep quality and the immunological system. METHODS An integrative bibliographical review was carried out using scientific articles from the last five years, from the PUBMED databases, with the descriptors: Sleep; Quarantine; COVID-19; Immunity; Mental Health. Besides the books "Oxford textbook of sleep disorders", "Cellular and molecular immunology", and "Treaty of Infectology". RESULTS Sleep affects immunity. This happens through the regulation of immunological markers and their cells. Therefore, the COVID-19 pandemic can promote sleep disturbances and harm the immune system function. CONCLUSION Sleep exercises a direct influence on immunity maintenance and immunological response. Circadian rhythm alterations, associated with the psychological problems imposed by the COVID-19 pandemic compromise the quality of sleep and, for that reason, the immune system.


RESUMO OBJETIVOS Analisar como a pandemia de COVID-19 (Sars-CoV-2) e as medidas de restrição social afetam a qualidade do sono e o sistema imunológico. MÉTODOS Fez-se uma revisão bibliográfica integrativa usando-se artigos científicos dos últimos cinco anos, das bases de dados PubMed, com os descritores: Sono; Quarentena; COVID-19; Imunidade; Saúde mental. Além dos livros Oxford textbook of sleep disorders, Cellular and molecular immunology e Tratado de infectologia. RESULTADOS O sono afeta a imunidade. Isso se dá por meio da regulação de marcadores imunológicos e suas células. Dessa forma, a pandemia de COVID-19 pode corroborar distúrbios de sono e prejudicar o funcionamento do sistema imune. CONCLUSÃO O sono exerce influência direta na manutenção da imunidade e da resposta imunológica. A alteração do ritmo circadiano, atrelada aos problemas psicológicos impostos pela pandemia de COVID-19, compromete a qualidade do sono e, dessa forma, o sistema imune.

ABSTRACT

Introdução: O equilíbrio corporal pode ser afetado por déficits visuais, proprioceptivos e/ou vestibulares centrais ou periféricas. Dentre as afecções vestibulares periféricos, a Vertigem Postural Paroxística Benigna apresenta grande interesse em pesquisas que buscam responder suas apresentações clínicas em adultos e sua associação com a integralidade dos demais sistemas corporais. Objetivo: Analisar as respostas de adultos jovens assintomáticos submetidos à semiologia do sistema vestibular. Metodologia: Estudo quantitativo, transversal analítico e descritivo, onde foram utilizados os testes de equilíbrio estático, dinâmico e a manobra de DixHallpike, com amostra de 30 voluntários assintomáticos recrutados em uma instituição de ensino superior do município de Parnaíba/PI. Resultados: O teste de apoio unipodal (1,87 ± 0,346) foi negativo (p < 0,001) e no teste de Fukuda (1,20 ± 0,407) grande parte tiveram resultados positivos (p < 0,001). Os testes de Romberg (2,00 ± 0,000), Romberg-Barré (1,50 ± 0,509) e Babinski-Weil (1,37 ± 0,490) não foram significantes (p = 0,001). Para a Manobra de Dix-Hallpike observamos que os movimentos de sedestação para decúbito dorsal esquerdo e de decúbito dorsal para sedestação direito e esquerdo foram significativos (p < 0,001). Conclusão: Os adultos jovens assintomáticos podem apresentar resultados positivos em teste de equilíbrio e sintomas na manobra de Dix-Hallpike, confirmando a Vertigem Postural Paroxística Benigna.(AU)


Introduction: Body balance can be affected by visual deficits, proprioceptive and/or central or peripheral vestibular. Among the peripheral vestibular disorders, the Benign Paroxysmal Positional Vertigo presents great interest in research seeking to answer clinical presentations in adults and its association with the completion of other body systems. Objective: To analyze the responses of asymptomatic young adults with symptoms of the vestibular system. Methods: This was a quantitative, descriptive analytical cross-sectional, where we used the tests of static balance, dynamic and Dix-Hallpike, with a sample of 30 asymptomatic volunteers recruited in a higher education institution in the city of Parnaíba/PI, Brazil. Results: The one-leg supporting roll 1.87 ± 0.346) was negative (p < 0.001) and the test Fukuda (1.20 ± 0.407) were largely positive (p < 0.001). The Romberg test (2.00 ± 0.000) Romberg-Barré (1.50 ± 0.509) and Babinski-Weil (1,37 ± 0.490) were not significant (p = 0.001). For the Maneuver Dix-Hallpike we observed that the movements of the sitting position to the left supine and supine to right and left sedestation were significant (p < 0.001). Conclusion: Asymptomatic young adults may have positive results on balancing test and symptoms in the Dix-Hallpike, confirming the Benign Paroxysmal Positional Vertigo. (AU)

ABSTRACT

Myelomeningocele (MMC) is a neural tube defect that often causes spinal cord injury at the thoracolumbar region, as well as sensory and motor paralysis in the lower limbs. This leads to continuous use of a wheelchair and, consequently, a sedentary lifestyle, predisposition to muscle weakness, cardiovascular and respiratory disorders, obesity, and structural alterations in the spine. We assessed the respiratory function and shoulder strength of MMC participants who were wheelchair-users and had no respiratory complaints and compared them to healthy children and adolescents. MMC (n=10) and healthy (n=25) participants of both genders with a mean age of 12.45 years (SD=2.1) were assessed for weight, height, respiratory performance, and isometric peak for shoulder flexors, extensors, abductors, and adductors, using an isokinetic dynamometer. Medullary lesion, functional levels, and abnormal curvatures of the spine were assessed for MMC participants. The level of spinal cord injury for the majority of the MMC participants was high lumbar and they had scoliosis. MMC showed lower values for forced vital capacity, forced expiratory volume at the first second, forced expiratory flow (25-75%), maximal voluntary ventilation, and isometric peak for shoulder flexors and adductors compared to healthy participants. This indicated a decreased vital capacity, respiratory muscle endurance, and shoulder muscle strength.

ABSTRACT

Purpose: This cross-sectional study evaluates the impact of self-perceived malocclusion on oral health-related quality of life (OHRQoL) and also whether aesthetic self-assessment is similar to professional evaluation. Methods : this cross- sectional study gathered 63 adults aged 18­36 years (28.68 ± 4.99), 42 women and 21 men, with no history of orthodontic treatment. OHRQoL was evaluated using the Brazilian short version of the Oral Health Impact Profile questionnaire (OHIP- 14). Perception of malocclusion was evaluated using the aesthetic component of the Index of Complexity, Outcome and Need (ICON), socioeconomic status and the Economic Classification Criteria of Brazil. Statistical analysis was conducted using the Mann­Whitney test, Spearman correlations and Wilcoxon test, with p < 0.05. Results : the overall average score and standard deviation for OHIP-14 was 5.17 (± 6.50). There was a weak correlation between the aesthetic component perceived by the participants and their evaluation of quality of life. Only the psychological domains (psychological discomfort and psychological disability) showed significant poor correlations. Gender and socioeconomic status did not affect aesthetic perception of malocclusion and OHRQoL. There was a significant difference between the professional assessments and those of participants. Conclusion : significant weak correlations between self- erceived malocclusion and OHRQoL were found in participants who were not seeking orthodontic treatment; the greatest impacts were seen in the domains of psychological discomfort and psychological disability, and aesthetic self-perceived malocclusion was significantly less relevant than the professional evaluation in this studied group.


Objetivo: Este estudo transversal teve como objetivo avaliar o impacto da má oclusão autopercebida na qualidade de vida relacionada à saúde bucal (OHRQoL) e também avaliar se a autoavaliação estética é semelhante à avaliação profissional. Métodos : Foram avaliados 63 adultos com idades entre 18 e 36 anos (28,68 ± 4,99), 42 mulheres e 21 homens, sem histórico de tratamento ortodôntico. A OHRQoL foi avaliada utilizando a versão brasileira do questionário Oral Health Impact Profile (OHIP-14). A percepção da má oclusão foi avaliada utilizando-se o componente estético do Índice de Complexidade, Resultado e Necessidade (ICON) e o nível socioeconômico foi avaliado com os Critérios de Classificação Econômica do Brasil. A análise estatística foi realizada pelo teste de Mann-Whitney, correlações de Spearman e teste de Wilcoxon, com p<0,05. Resultados : A pontuação média geral e desvio padrão para o OHIP-14 foi de 5,17 (±6,50). Houve fraca correlação entre o componente estético percebido pelos participantes e a avaliação de sua OHRQoL. Apenas os domínios psicológicos (desconforto psicológico e incapacidade psicológica) apresentaram correlações significativas, porém pobres. O sexo e o nível socioeconômico não afetaram a percepção estética da má oclusão e a OHRQoL. Houve diferença significativa entre as avaliações profissionais e dos participantes. Conclusão : Correlações fracas e significativas entre a má-oclusão autopercebida e a OHRQoL foram encontradas em participantes que não procuravam tratamento ortodôntico, onde os maiores impactos foram observados nos domínios desconforto psicológico e incapacidade psicológica. A má-oclusão estética percebida pelos participantes foi significativamente menos relevante do que a avaliação profissional neste grupo estudado.

ABSTRACT

ABSTRACT Objective: This clinical study was conducted in order to evaluate force decay over time of latex and non-latex orthodontic intraoral elastics. Methods: Patients (n = 15) were evaluated using latex and non-latex elastics in the periods of : 0, 1, 3, 12 and 24 hours. The rubber bands were transferred to the testing machine (EMIC DL-500 MF), and force values were recorded after stretching the elastic to a length of 25mm. Paired t test was applied and analysis of variance (ANOVA) was used to evaluate the variation of force generated. LSD (Fisher's least significant difference) post-hoc test was thus employed. Results: As regards the initial forces (zero time), the values of force for non-latex elastic were slightly higher than for the latex elastic. In the subsequent times, the forces generated by the latex elastic showed higher values. Regarding the material degradation, at the end of 24 hours the highest percentage was observed for non-latex elastic. Conclusions: The latex elastics had a more stable behavior during the studied period, compared with non-latex.


RESUMO Objetivo: o objetivo deste estudo clínico foi avaliar e comparar o comportamento dos elásticos de látex e não látex quanto à perda de força ao longo do tempo. Método: os pacientes (n = 15) foram avaliados usando ambos os tipos de material (látex e não látex) em cada tempo: 0, 1, 3, 12 e 24 horas. Os elásticos foram transferidos para a máquina de ensaios mecânicos (EMIC DL-500 MF) e os valores de força foram registrados após a distensão dos elásticos a uma distância de 25 mm. Foi aplicado o teste t pareado, e a análise de variância (ANOVA) foi realizada para verificar a variação das forças geradas em todos os tempos estudados. Em seguida, o teste post-hoc LSD (Fisher's least significant difference) foi aplicado. Resultados: quanto às forças iniciais (tempo zero), os valores de força dos elásticos não látex foram ligeiramente maiores do que dos elásticos de látex. Nos tempos subsequentes, as forças geradas pelos elásticos de látex apresentaram valores superiores às geradas pelos elásticos não látex. Em relação à degradação do material, ao fim do período de 24 horas, o maior percentual foi observado pelos elásticos não látex. Conclusões: os elásticos de látex apresentaram comportamento mais estável durante o período de estudo, em comparação aos não látex.

ABSTRACT

ABSTRACT Objective: This cross-sectional observational study was designed to assess the biosafety conducts adopted by orthodontists, and possible differences regarding training time. Methods: Both the application of methods for sterilization/disinfection of instruments and materials, and the use of personal protective equipment (PPE) were collected through questionnaires via e-mail. Results: The questionnaires were answered by 90 orthodontists with a mean age of 37.19 ± 9.08 years and mean training time of 13.52 ± 6.84 years. Regarding orthodontic pliers, 63.23% use an autoclave, except 1 who does not perform any procedure. All participants use autoclave to sterilize instruments, and 95.6% of respondents perform cleaning with chemicals prior to sterilization. Most of them (65.56%) use an autoclave to sterilize orthodontic bands, with some still associating disinfection methods, while few (18.89%) do nothing at all. There was a high incidence of the answer "nothing" for the methods used for elastic, accessories, bandages, metal springs, and arches. All respondents use mask and gloves in attendance, 78.92% use aprons, 58.92% use protective goggles, and 50.01% use cap. Training time significantly influenced (p = 0.003) only the use of glutaraldehyde for sterilization/disinfection of pliers. Conclusions: The sterilization and cleaning of pliers, instruments, and bands, besides the use of PPE, received more uniform and positive responses, while other items suggest disagreements and possible failures. Only orthodontists trained for more than 13 years choose using glutaraldehyde for pliers sterilization/disinfection, the only adopted method with a significant difference in relation to training time.


RESUMO Objetivo: o presente estudo observacional transversal foi delineado para avaliar as condutas de biossegurança adotadas pelos ortodontistas, e as possíveis diferenças em função do tempo de formação. Métodos: tanto as técnicas de esterilização e desinfecção de instrumentais e materiais quanto o uso de equipamentos de proteção individual da equipe foram coletados por meio de questionários via e-mail. Resultados: os questionários foram respondidos por 90 ortodontistas, com idade média de 37,19 ± 9,08 anos e tempo médio de formação de 13,52 ± 6,84 anos. Quanto aos alicates ortodônticos, 63,23% usam autoclave, exceto aqueles que não realizam nenhum procedimento. Houve total abrangência no uso da esterilização do instrumental por autoclave, sendo que 95,6% realizam a limpeza com substâncias químicas previamente à esterilização. A maioria (65,56%) utiliza autoclave para a esterilização de anéis ortodônticos e alguns associam métodos de desinfecção, mas 18,89% nada fazem. Houve alta incidência da resposta "nada" para os métodos utilizados em elásticos, acessórios, ligaduras, molas e arcos. Todos os questionados utilizam máscara e luva no atendimento ortodôntico, 78,92% incluem o uso do avental, 58,92% usam óculos de proteção e 50,01% vestem o gorro (50,01%). O tempo de formação influenciou significativamente (p= 0,003) apenas no uso do glutaraldeído para esterilização e/ou desinfecção dos alicates. Conclusões: a esterilização e limpeza de alicates, instrumental de exame, aplicador de elásticos e anéis ortodônticos, além do uso de equipamentos de proteção individual, receberam respostas mais uniformes e positivas, enquanto os outros itens sugerem falhas. Apenas os ortodontistas formados há mais de treze anos optaram pelo uso do glutaraldeído para esterilização/desinfecção dos alicates ortodônticos, sendo a única conduta que mostrou diferença significativa em relação ao tempo de formação.

ABSTRACT

The aim was to study pregnant cervus in captivity, to obtain body morphometric data, serum progesterone concentrations, and pH of the vagina. Females of cervus (Cervus unicolor), (n=8) between 2 and 3 years old were used in November during breeding season. After sedation, in one collection, the following was measured: body weight 54.50 ± 18.70kg, body length 1.21 ± 0.16m, height at withers 0.75 ± 0.08m, thoracic perimeter 0.84 ± 0.12m, and body mass index 97.32 ± 10.50kg / m2. After sedation, blood samples were collected to measure progesterone concentration by radioimmunoassay and the use of an indicator tape to obtain the pH of the vagina was performed eight times at four day intervals in the eight females, in a total of 64 samples for each exam. Data were analyzed, and significance was at 5%. There were no differences (P> 0.05) between measurements for serum progesterone concentrations and pH of the vagina. The correlations between body weight, progesterone, pH, and body mass index were not significant (P> 0.05). There was no significant oscillation of progesterone concentration and pH of the vagina in the pregnancy period studied.

ABSTRACT

Aim: This study was conducted in order to evaluate and compare the behavior of latex and non-latex elastics, as the loss of strength over time in vitro. Methods: The study evaluated 15 of each elastic material for the pre-selected times: 0, 1, 3, 12 and 24 hours. The rubber bands were transferred to the testing machine (EMIC DL-500 MF). The force values were recorded after stretching the elastic to a length of 25mm. Independent t-test was applied. Analysis of variance (ANOVA) was used to check the variation of the forces generated between those determined times. To identify between which times the difference was present, Tukey post-hoc test was accomplished. Results: As regards the initial forces (zero time), the values of force for non-latex elastic were slightly higher than the latex elastic. In subsequent times, the forces generated by the latex elastic showed higher values. Regarding the material degradation, at the end of 24 hours the highest percentage was observed for non-latex elastic. Conclusion: The latex elastic had a more stable behavior during the studied period compared with non-latex. Thus, it is suggested that the non-latex elastics should be changed more frequently and that larger initial forces must be applied than the látex elastics

ABSTRACT

AIM: To investigate if there is agreement between measurement values obtained for Brazilian adults and the values recommended by Holdaway, Merrifield, Burstone, Steiner and Ricketts, for facial profile soft tissue analysis. METHODS: A sample of 30 cephalometric radiographs was used, consisting of 15 women and 15 men, aged 18 to 31 years, all exhibiting excellent occlusion and balanced facial profile. Comparisons were made with the measurement values proposed by the aforementioned authors using Student's t-test and to determine the correlation between the ANB and Â-H measurement values described by Holdaway, using Pearson's correlation coefficient. RESULTS: Among the measures evaluated, 4 showed statistically significant differences: Â.Z (Merrifield), S-LS and S-LI (Steiner), and E-LI (Ricketts) relative to the standards recommended by the authors. The measurement values advocated by Merrifield, Steiner and Ricketts showed statistical differences, and as for the Z-angle, Brazilians feature a slightly more convex profile, which appeared slightly concave according to Steiner, and according to the E-Plane (Ricketts), it meant an increased protrusion of the lower lip. CONCLUSION: It could be asserted that adult Brazilians have a slightly more convex facial profile than US standards, but these differences should be viewed with caution, as they are clinically unimportant (AU)

ABSTRACT

Tuberculous Meningitis (TBM) is a severe manifestation of tuberculosis that represents 1% of the cases of infection by Mycobacterium tuberculosis. Children are among the other age groups the most affected and when present, HIV-1 is responsible for poorer prognosis. It was carried out a search on the databases of Pubmed, Lilacs and Scielo, looking for articles that approach the principals news aspects of neurologic complications caused by TBM. The literature cite as major neurologic findings the hydrocephalus in approximately 80% patients, meningeal irritation, coma, seizures, intracranial pressure signs, cranial nerve palsy, hemiparesis and disorders in the movement. Neurologic sequelae occur in up to 50% of survivors and early diagnosis is crucial to reduce the occurrence of major functional losses. In this way, discussions presenting more specific methods for TBM as well as better assessment of the signs and symptoms of the disease is necessary for a better prognosis and lower mortality rate of these patients.


A meningite tuberculosa (MTB) é uma manifestação grave da tuberculose que representa 1% dos casos de infecção por Mycobacterium tuberculosis. As crianças estão as faixas etárias mais afetadas e quando presente, o HIV-1 é responsável pelo pior prognóstico. Foi realizada uma revisão de bancos de dados Pubmed, Lilacs e Scielo, à procura de artigos que abordem os principais aspectos das complicações neurológicas causadas pela MTB. Os principais achados neurológicos compreendem a hidrocefalia em aproximadamente 80% dos pacientes, irritação meníngea, coma, convulsões, sinais de pressão intracraniana, paralisia de nervo craniano, hemiparesia e distúrbios movimento. Sequelas neurológicas ocorrem em até 50% dos sobreviventes e o diagnóstico precoce é crucial para reduzir a ocorrência de perdas. Desta forma, as discussões apresentando métodos mais TBM, bem como uma melhor avaliação dos sinais e sintomas da doença é necessária para um melhor prognóstico e menor taxa de mortalidade desses pacientes.

ABSTRACT

A meningite bacteriana é uma afecção de grande significância devido a sua relação com alta mortalidade e morbidade na população neonatal a jovem. Devido a este fato é importante o conhecimento sobre esta doença e os seus principais agentes etiológicos. Com o objetivo de relatar os principais métodos de diagnóstico, assim como os principais agentes etiológicos envolvidos na fisiopatologia da meningite bacteriana em população jovem foi realizada uma busca por artigos publicados nos últimos 5 anos nas bases de dados Pubmed, Scielo, Bireme e Lilacs. A literatura atual aponta como microrganismos predominantes na incidência dessa doença a N. meningitidis S. pneumoniae, sendo as mais recorrentes na população de faixa etária entre 29 dias e 17 anos. Os fatores relacionados ao prognóstico estão intimamente relacionados com a distinção da classificação do agente etiológico em bacteriano ou viral, importante para a determinação da terapia adequada.


Bacterial meningitis is a highly significant disease due to its relationship with high mortality and morbidity in neonatal and young population. Due to this is important to know about this disease and its main etiological agents. In purpose to report the main diagnostic methods, as well as the main etiological agents involved in the pathophysiology of bacterial meningitis was conducted a search for articles published in the last five years in Pubmed, Scielo, Bireme and Lilacs. The current literature indicates N. meningitidis S. pneumoniae the most predominant microorganisms in the incidence of this disease between population aged between 29 days and 17 years. Factors related to prognosis are closely related to the classification distinction of the etiologic agent in bacterial or viral, important to determine the ap- propriate therapy.

ABSTRACT

O presente trabalho teve por objetivo avaliar a conversão alimentar (CA) por meio da inferência bayesiana considerando-se análises bivariadas. Foram utilizadas diferentes espécies animais de experimentos conduzidos na Universidade Federal de Viçosa, no estado de Minas Gerais, Brasil. O modelo proposto mostrou ser apropriado, uma vez que possibilitou a detecção de diferenças significativas entre níveis de fatores não detectados por procedimentos frequentistas em ANOVA tradicional, principalmente em pequenas amostras. No experimento com codornas, evidenciou-se que aves cujos níveis de proteína bruta eram de 23% e 29%, respectivamente, para machos e fêmeas, apresentaram uma melhor CA, de 2,83±0,03 e 2,66±0,03, respectivamente. No experimento com frangos, no grupo sem o aditivo antibiótico, a inclusão de 0,02% de extrato de ésteres naturais foi o que promoveu a melhor CA (1,72±0,01), e, de modo geral, o uso de antibiótico e a ausência de ésteres naturais promoveram CA de 1,63±0,02. Em caprinos, verificou-se que o aleitamento, seja com leite de cabra ou de vaca, promove igualmente uma melhor CA, respectivamente, no grupo de 60 e 90 dias, de 1,29±0,14 e 1,79±0,11, sugerindo que o aleitamento seja feito até os 60 dias. Em suínos, a dieta com maior nível de energia metabolizável e aminoácidos foi a que promoveu a melhor CA (2,86±0,07), quando comparada a uma dieta com nível nutricional mais baixo. Já o uso de enzimas na dieta com menor nível energético e de aminoácidos proporcionou resultado intermediário (2,90±007). Em bovinos, observou-se que o uso de 1% de concentrado na dieta promoveria uma melhor CA estimada de 7,33±0,35 entre os Nelores e que essa promoção seria de 7,40±0,58 entre os cruzados com o uso de 2% de concentrado na dieta.


The aim of this study was to evaluate the feed conversion (CA) by Bayesian inference in bivariate considering analyzes in real and simulated data. Different animal species experiments conducted at the Universidade Federal de Viçosa, state of Minas Gerais, Brazil are used. The proposed model proved to be appropriate once it enabled the detection of significant differences between levels of factors not detected by frequentist procedures with traditional ANOVA, especially in small samples. In the experiment with quails, it became clear that the birds' brute protein levels were 23% and 29%, respectively, for males and females, which presented better CA, 2.83±0.03 and 2.66±0.03, respectively. In the experiment with chickens, the group without additive antibiotic, including 0.02% extract natural esters promoted the best CA (1.72±0.01) and in general antibiotic absence of esters natural promoted 1.63±0.02 of the CA. In goats, it has been found that feeding milk from cows or goats also promotes better CA, respectively, in groups milked up to 60 and 90 days, being 1.29±0.14 and 1.79±0.11, suggesting that suckling done until 60 days. Pigs fed the highest level of metabolizable energy and aminoacids promoted the best CA (2.86±0.07) compared to a diet with lower nutritional level. But the use of enzymes in the diet with lower energy level and amino acid provided intermediate result (2.90±007). In cattle, it was observed that the use of 1% concentrate diet, CA, promotes a better estimate of 7.33±0.35 between Nellore and this promotion would be 7.40±0.58 between the cross breeds using 2% concentrate diet.
