Saúde física e emocional de cuidadores da cidade de Santa Cruz-RN: perfil epidemiológico e fatores associados

Taking care for an impaired elderly is a hard and costly task that could affect directly the caregiver health. The purpose of this study was to evaluate the physical and mental health of elderly caregivers from the city of Santa Cruz-RN and analyze the potential correlated factors through an observational analytic design of a crosssectional. A multidimensional questionnaire was used to evaluation of the social demographics characteristics and those related to the care activity, as well as the caregivers´ physical and mental health. It was realized a descriptive analyze using frequency distribution and measures of the central tendency and dispersion to description of the caregivers. To verify the magnitude of the association between the variables was used the bivariate analysis through the Pearson and Spearman correlations and qui-square test. To evaluation of the association of the correlated factors to the adverse outcome with the caregivers´ physical and mental health was made a multivariate analysis by logistic binary regression and multiple linear regression models. The final sample was constituted by 304 persons, mostly women with a mean age of 50.3 ±16.8 years. The principal factors related to the physical health were age, stress and life satisfaction. Be a male caregiver, caring for a little while the elderly with cognitive deficit and not been spouse were related to worse mental health. Have worse physical health, high stress, depressive symptomatology, burden and low levels of satisfaction were also related to the mental health. After adjust through multiple linear regression was observed R2 values of R2=0,21 for Stress, R2 =0,17 for Depressive Symptomatology, R2 =0,21 for Burden and R2 =0,16 for Satisfaction. The attainment of the factors associated with caregiver´s health can help in the elaboration of specifics politics witch the goal is the integral attention to the elderly and his caregiver. The inability of continuous taking care could result in adverse outcomes such as institutionalization, impairment and death

Engenharia nos sertões nordestinos: o Gargalheiras, a Barragem Marechal Dutra e a comunidade de Acari, 1909-1958

In Brazil, between the late nineteenth and early decades of the twentieth, polytechnic engineers assumed an important role in discussing the establishment of a modern country. The problem of drought in northeastern Brazil gave the professionals performance, within an interventional process more mounts, the conception plans and measures for the purposeful integration of the territory afflicted. With the foundation of Inspetoria de Obras Contra as Secas (IOCS), in 1909, the actions to combat drought and would be institutionalized, them, studies performed out by technical and scientific committees would be systematically applied in the Brazilian Northeast. So, This work was central objective understand the historical process inplantation of a whole infrastructure of modern character by professional technical and their consequences within the Northeast Geographic space, in specific, in the municipality of Acari in the State of Rio Grande do Norte, in the first half of the twentieth century. The politics of the government, through technical education and scientific engineers polytechnics, would emphasize, during the twentieth century, the building of dams, and irrigation canals, wells, railways, highways, between other elements, that would soon transform the physical space-northeast, specifically, the territory acariense. These works began to contribute to the setting of man backcountry their land, promote the regular practice of agriculture even in periods of drought and, the integration, especially, economic of territory acariense the other producing regions of Rio Grande do Norte and the Northeast as well as promoting the modification of the landscape of the world backcountry. These actions functioned as elements of modernity and progress that transformed the space by favoring by favoring the formation of urban networks (urban) in this space

Efeito in vitro da terapia fotodinâmica sobre bactérias orais em suspensão e na formação de biofilme : ensaio com azul de metileno e toluidina ativados por luz halógena

Photodynamic therapy (PDT) has been proposed as an alternative method for the treatment of biofilm-dependent oral diseases like dental caries. This therapy consists of simultaneous action of a visible light (L) and a photosensitizer (FS) in the presence of oxygen, which leads to production of different reactive oxygen species that can interact with the bacterial cell components, and promote cell death. This study aims to evaluate the antimicrobial action of PDT on oral bacteria in suspension, as well as the formation of mono and multi-species biofilms, in vitro, from a standard strain of Streptococcus mutans (ATCC 25175) and saliva samples, respectively. The dye methylene blue (MB) and toluidine blue (TB) were used at a concentration of 100 mg/ L and activated by halogen light (600 to 750 nm) from a modified hand held photopolymerizer (Ultralux ®, Dabi Atlante, Ribeirão Preto , São Paulo, Brazil.). Planktonic cultures were prepared and submitted to different experimental conditions: 1. PDT using TB 2. PDT using MB, 3. L+ FS- , 4. TB + L - ; 5. MB+ L-; 6. L- FS- (negative control) and 7. administration of 0.12% chlorhexidine digluconate (positive control) (Periogard ®, Colgate-Palmolive Company, New York, USA). The immediate and mediated action of PDT on bacterial suspensions, as well as its effect on biofilm formation were observed from the number of colony-forming units per milliliter (CFU/mL) and measures optical density (OD). The data were statistically analyzed using the Kruskal-Wallis and Mann-Whitney test for the significance level of 5%. According to the results, the PDT showed no antibacterial action on suspensions of S. mutans, regardless of the dye used. PDT with MB activated by halogen light was able to reduce 86.6% CFU/mL multi-species planktonic cultures, however, this reduction was not significant (p > 0.05). PDT showed antibacterial effect, mediate on multi-species planktonic cultures with TB (p < 0.001) and MB (p < 0.001), activated by halogen light. PDT was able to prevent the formation of multispecies biofilm, through the activation of TB by halogen light (p = 0.01). We conclude that activation of the dye toluidine blue and methylene blue, by halogen light (PDT) showed antimicrobial activity, compared to multi-species planktonic cultures prepared from saliva samples

Influência das condições de saúde bucal no desempenho das atividades diárias de adolescentes escolares

Instruments are used in odontology to measure the Quality of Life Related to Oral Health (OHRQoL) to scale how the oral condition interferes with functional areas, of the people s psychological and social life. This cross-sectional study, held in Natal/RN, with 215 students from the Federal Institute of Education, Science and Technology of Rio Grande do Norte (IFRN) has investigated the association between the performance of daily activities and oral health status of school adolescents from 15 to 19 years of age, through the normative index DMFT (permanent teeth decayed, missing and filled), CPI (Community Periodontal Index) and DAI (dental Aesthetic Index) and subjective questionnaire assessment of quality of life related oral health OIDP index (oral impacts on daily performance). It was also carried out the socioeconomic characteristics of students through IFRN own data. Concerning the analysis of data was performed a descriptive analysis of the variables by their absolute and relative frequencies and measures of central tendency. The chi-square test was used to assess the association between the dependent variable and the independent categorical variables and the Student t test for quantitative. It was also conducted a further multiple analysis out using Poisson regression with robust variance between the outcome "presence of impact" and the independent variables that showed p <0.20. It was used for all the statistical tests a significance level of 5%. Among the adolescents surveyed, 51.16% reported that at least one activity assessed by OIDP had hampered its implementation due to some dental problem. The difficulties were more pronounced in the activities of eating (31.6%), oral hygiene (25.6%) and smile (25.1%).The tooth position, followed by toothache, were the causes of the impacts reported by most teenagers. There was a significant association between the presence and impact of the presence of one or more decayed teeth (p = 0.012), the presence of gum bleeding (p = 0.012) and for orthodontic treatment (p = 0.003), independently of other variables. There was no significant association between oral health status and socioeconomic and demographic characteristics of the adolescents. The survey results showed that there is an association between oral health status of the population studied and reports of difficulties in carrying out daily activities evaluated. The worse the oral health status, the greater the impact of this condition on the adolescents quality of life

Utilizando Pesos estáticos e dinâmicos em sistemas multi-classificadores com diferentes níveis de diversidade

Although some individual techniques of supervised Machine Learning (ML), also known as classifiers, or algorithms of classification, to supply solutions that, most of the time, are considered efficient, have experimental results gotten with the use of large sets of pattern and/or that they have a expressive amount of irrelevant data or incomplete characteristic, that show a decrease in the efficiency of the precision of these techniques. In other words, such techniques can t do an recognition of patterns of an efficient form in complex problems. With the intention to get better performance and efficiency of these ML techniques, were thought about the idea to using some types of LM algorithms work jointly, thus origin to the term Multi-Classifier System (MCS). The MCS s presents, as component, different of LM algorithms, called of base classifiers, and realized a combination of results gotten for these algorithms to reach the final result. So that the MCS has a better performance that the base classifiers, the results gotten for each base classifier must present an certain diversity, in other words, a difference between the results gotten for each classifier that compose the system. It can be said that it does not make signification to have MCS s whose base classifiers have identical answers to the sames patterns. Although the MCS s present better results that the individually systems, has always the search to improve the results gotten for this type of system. Aim at this improvement and a better consistency in the results, as well as a larger diversity of the classifiers of a MCS, comes being recently searched methodologies that present as characteristic the use of weights, or confidence values. These weights can describe the importance that certain classifier supplied when associating with each pattern to a determined class. These weights still are used, in associate with the exits of the classifiers, during the process of recognition (use) of the MCS s. Exist different ways of calculating these weights and can be divided in two categories: the static weights and the dynamic weights. The first category of weights is characterizes for not having the modification of its values during the classification process, different it occurs with the second category, where the values suffers modifications during the classification process. In this work an analysis will be made to verify if the use of the weights, statics as much as dynamics, they can increase the perfomance of the MCS s in comparison with the individually systems. Moreover, will be made an analysis in the diversity gotten for the MCS s, for this mode verify if it has some relation between the use of the weights in the MCS s with different levels of diversity

Construct validity of a figure rating scale for Brazilian adolescents

Background: Figure rating scales were developed as a tool to determine body dissatisfaction in women, men, and children. However, it lacks in the literature the validation of the scale for body silhouettes previously adapted. We aimed to obtain evidence for construct validity of a figure rating scale for Brazilian adolescents.Methods: The study was carried out with adolescent students attending three public schools in an urban region of the municipality of Florianopolis in the State of Santa Catarina (SC). The sample comprised 232 10-19-year-old students, 106 of whom are boys and 126 girls, from the 5th series (i.e. year) of Primary School to the 3rd year of Secondary School. Data-gathering involved the application of an instrument containing 8 body figure drawings representing a range of children's and adolescents' body shapes, ranging from very slim (contour 1) to obese (contour 8). Weights and heights were also collected, and body mass index (BMI) was calculated later. BMI was analyzed as a continuous variable, using z-scores, and as a dichotomous categorical variable, representing a diagnosis of nutritional status (normal and overweight including obesity).Results: Results showed that both males and females with larger BMI z-scores chose larger body contours. Girls with higher BMI z-scores also show higher values of body image dissatisfaction.Conclusion: We provided the first evidence of validity for a figure rating scale for Brazilian adolescents.

Comunidade fitoplanctônica como discriminador ambiental em açude eutrófico tropical semiárido (Barragem Armando Ribeiro Gonçalves, RN) e divulgação científica para reflexão social

The knowledge of the phytoplankton community, as an integral and dynamic processes of eutrophication, provides information essential for proper management and handling. A growing problem of cyanobacteria in reservoirs around the world as a result of artificial eutrophication processes, generating a particular concern, because some species produce cyanotoxins, which can cause adverse effects on human health. The present work aims to characterize the spatial and temporal dynamics of phytoplankton, assessing their potential as ecological indicator of water quality in reservoirs semiarid region. The samples of water were collected monthly between 2009 and 2011, at three points along the dam Armando Ribeiro Gonçalves / RN. In each sample were measured physico - chemical analysis of water and biological components. We conducted a scientific dissemination activity, with distribution and reading primer on eutrophication, informative talk about water quality, questionnaires and performing a play in a public school in the city of Itajá / RN. The reservoir was considered eutrophic in three points, taking into account the values of chlorophyll -a and phosphorus, adopted to characterize eutrophic environments of semi-arid areas. High density of cyanobacteria, with a maximum value of 2.227.862 cél.ml- 1 and minimum of 43.456 cél.ml- 1 was recorded in lentic and semilêntico points throughout the study, exceeding the levels of drinking water (20.000 cél.ml- 1) established in 2.914/2011 Ordinance of the Ministry of Health of Brazil. All samples contained microcystin, and 44 % had values superiores1μg L- 1. The thermal pattern of the water column showed micro stratifications with differences of less than 1 ° C from five feet deep. The distribution pattern was the type profile clinogrado with oxygen deficit in the bottom of the reservoir. Oxiclina from 10 meters depth was observed during the rainy season (May-June) in the two years of study. The phytoplankton community was represented by 10 functional groups: S1, M, H1, Lo, P, F, Sn, P, W2 and R. The assessment of the ecological status of the system by the index Q showed poor water quality. The results of the study show that the vertical variations were less pronounced than the seasonal variations of cyanobacteria and phytoplankton community in general in the reservoir. The presence of cyanotoxins confirms the need for the monitoring of water quality and measures to reduce eutrophication in water supply reservoirs semiarid RN and demonstrates the challenge for water managers and health authorities to ensure water quality and consequently minimize risks to human health. Compared to the lecture, the primer was considered more efficient in sensitizing the participants, featuring a dynamic practice, differentiated learning, create opportunities for students to rethink attitudes of respect and care for the environment, and shall have the opportunity to learn the subject content from your reality and living environment. The knowledge generated from the activity of scientific were seen as essential for raising awareness of some of the region`s environmental problems , such as eutrophication

Alho em pó na alimentação alternativa de frangos de corte

O objetivo deste trabalho foi estudar o efeito da inclusão de alho em pó (Allium sativum) em rações para frangos, sobre desempenho, rendimento de carcaça e partes, peso de órgãos, níveis de colesterol e triacilgliceróis sangüíneos, e morfometria intestinal. Foram utilizados 720 pintainhos machos Cobb, com um dia de idade, distribuídos em blocos casualizados com seis tratamentos: ração sem promotor de crescimento (PC), sem anticoccidiano (AC) e com 0,00, 0,25, 0,50, 0,75 e 1,00% de alho; e ração com PC+AC, com quatro repetições de 30 aves cada. Peso, ganho de peso, consumo de ração, conversão alimentar e mortalidade foram obtidos aos 21 e 42 dias de idade. Aos 42 dias de idade foram abatidas 20 aves por tratamento para determinação do rendimento de carcaça e 4 aves para avaliação do peso de órgãos e morfometria intestinal. Sangue de 8 aves por tratamento foi colhido para determinação de colesterol e triacilgliceróis. em aves alimentadas até 42 dias de idade com ração sem promotor de crescimento e anticoccidiano, a inclusão de até 1,00% de alho em pó beneficiou a conversão alimentar e não alterou o rendimento de carcaça e partes, peso relativo dos órgãos, mucosa intestinal, nem os níveis séricos de colesterol e triacilgliceróis. O alho não substitui com eficiência o antibiótico usado como promotor de crescimento em rações de frangos.

Desempenho, características de carcaça e resultado econômico de cordeiros criados em creep feeding com silagem de grãos úmidos de milho

Objetivou-se, com este trabalho, estudar níveis de substituição (0; 50 e 100%) do milho grão seco moído pela silagem de grãos úmidos de milho na ração de cordeiros alimentados em creep feeding. Vinte e quatro cordeiros Suffolk foram avaliados quanto ao desempenho, pesos e rendimentos das carcaças. Também foi realizada uma análise econômica. As rações foram fornecidas ad libitum, sendo suas sobras pesadas para o cálculo do consumo médio por animal. Ao atingirem 28 kg de peso vivo, os cordeiros foram submetidos a jejum por 16 horas e, então, novamente pesados para se obter o peso vivo ao abate. Após o abate, os animais foram eviscerados para se obterem os pesos e rendimentos de carcaça quente. As carcaças permaneceram por 24 horas em câmara de refrigeração, sendo novamente pesadas para se obterem os rendimentos de carcaça fria e as perdas por resfriamento. Os resultados revelaram que não houve efeito dos níveis de substituição sobre ganho médio diário de peso vivo, idade ao abate, pesos e rendimentos das carcaças quentes e frias, indicando que a silagem de grãos úmidos de milho pode ser utilizada em substituição ao milho moído na alimentação de cordeiros. Como o peso ao abate foi pré-fixado, as variações nas idades ao abate fizeram com que essa variável exercesse influência sobre os desempenhos, pesos e rendimentos e, quanto maiores essas idades, piores os resultados dos parâmetros avaliados. O tratamento com 50% de silagem de grãos úmidos apresentou os melhores resultados econômicos e o tratamento sem silagem de grãos úmidos foi o de menor rentabilidade.

Medidas objetivas das carcaças e composição química do lombo de cordeiros alimentados e terminados com três níveis de proteína bruta em creep feeding

Objetivou-se avaliar o efeito de três níveis de proteína (15, 20 e 25% PB) na ração sobre as medidas objetivas das carcaças e do músculo Longissimus dorsi, os pesos e rendimentos dos cortes, além da composição química e maciez da carne de cordeiros Suffolk alimentados e terminados em creep feeding. Foram utilizados 15 cordeiros inteiros, originados de partos simples, abatidos ao atingirem peso vivo final de 28 kg. As carcaças foram mantidas em câmara de refrigeração a 5ºC, durante 24 horas, para registro das medidas objetivas, realizado após separação dos cortes comerciais, na meia-carcaça esquerda. A área do músculo Longissimus dorsi foi mensurada para determinação da área de olho de lombo (AOL cm²). No lombo esquerdo congelado, realizou-se a análise de composição química e, no direito, também congelado, o teste de maciez peloWarner Bratzler Shear Force. Os níveis de proteína bruta não influenciaram as medidas objetivas de carcaça nem as do músculo Longissimus dorsi. Houve efeito significativo para peso e rendimento da paleta, com superioridade para o tratamento contendo 25% de proteína bruta. Nas análises químicas do músculo Longissimus dorsi, observou-se efeito significativo para extrato etéreo, cinzas e maciez. No sistema de alimentação e terminação de cordeiros Suffolk em creep feeding, a ração formulada com farelo de soja como fonte protéica deve ser balanceada com 25% de proteína bruta por diminuir o teor de gordura e melhorar a maciez da carne e o peso e rendimento da paleta, sem afetar as medidas objetivas da carcaça, os demais pesos e os rendimentos dos cortes.

Silagem de grãos úmidos de milho na alimentação de frangos de corte

O objetivo deste trabalho foi avaliar a silagem de grãos úmidos de milho (SGUM) como ingrediente nas rações de frangos de corte, em substituição total aos grãos secos de milho (GSM), no desempenho, no rendimento da carcaça, no peso dos órgãos e na morfologia intestinal. No primeiro experimento, 600 pintainhos machos Ross foram distribuídos em blocos casualizados, com seis tratamentos (A: GSM de 1-42 dias; B: SGUM de 1-42 dias; C: SGUM de 1-7 dias e GSM de 8-42 dias; D: SGUM de 1-14 dias e GSM de 15-42 dias; E: SGUM de 1-21 dias e GSM de 22-42 dias; F: GSM + água de 1-42 dias), com quatro repetições, de 25 aves. No segundo experimento, foram utilizados 24 pintainhos machos Ross, distribuídos ao acaso, em dois tratamentos (com e sem SGUM) e 12 repetições cada. A SGUM até 21 dias de idade não interferiu no desempenho das aves e no rendimento de carcaça aos 42 dias de idade. Frangos alimentados com SGUM apresentaram maior peso relativo do fígado, menor largura das vilosidades do duodeno e íleo, maior altura de vilosidade no jejuno aos 21 dias, e menor profundidade de cripta no duodeno e no íleo aos 42 dias de idade. A SGUM pode ser considerada um ingrediente em dietas de frangos de corte até 21 dias de idade, por não interferir no peso final das aves, no rendimento de carcaça e peso dos órgãos.
