Perfil periodontal de pacientes portadores de alterações endócrino-metabólicas

Objective- Convinced that periodontium, many times, can show alterations in human health, the aim of these studies was to investigate the periodontal situation in patients with endocrine-metabolic disorders such as, Berardinelli-Seip Syndrome, hyperthyroidism, hypothyroidism and acromegaly. Methods- Eight patients with Berardinelli-Seip Syndrome, 16 acromegalics, 30 hypothyroids, 30 hyperthyroids, and a control group with 35 patients were evaluated. Clinical attachment loss, probing depth, gingival bleeding index, gingival overgrowth and Index of Decayed, Missing and Filled Teeth were measured in each patient. All ethical aspects were rigidly observed, being the study conducted after its approval by the University of Fortaleza Research Ethics Committee. Results- The presence of periodontitis was marked in hyperthyroids and in patients with Berardinelli-Seip Syndrome. Hypothyroids showed not much presence of periodontitis, while all acromegalics presented absence of periodontitis. Conclusions- The protective effect of periodontitis in acromegalic patients is a new finding, whose mechanisms are not yet clear, but may be related to the anabolic effects of growth hormone. The presence of periodontitis in Berardinelli-Seip Syndrome may occur due the early onset of diabetes. In hyperthyroids, the high prevalence of periodontitis could be linked to thyroid hormones effects on bone, explaining also the minor prevalence in hypothyroids

Desenvolvimento de um software de comunicação sem fio aplicado à instrumentação de unidade de elevação de petróleo tipo Plunger Lift

This dissertation aims to develop a software applied to a communication system for a wireless sensor network (WSN) for tracking analog and digital variables and control valve of the gas flow in artificial oil s elevation units, Plunger Lift type. The reason for this implementation is due to the fact that, in the studied plant configuration, the sensors communicate with the PLC (Programmable and Logic Controller) by the cables and pipelines, making any changes in that system, such as changing the layout of it, as well as inconveniences that arise from the nature of the site, such as the vicinity s animals presence that tend to destroy the cables for interconnection of sensors to the PLC. For software development, was used communication polling method via SMAC protocol (Simple Medium Access ControlIEEE 802.15.4 standard) in the CodeWarrior environment to which generated a firmware, loaded into the WSN s transceivers, present in the kit MC13193-EVK, (all items described above are owners of Freescale Semiconductors Inc.). The network monitoring and parameterization used in its application, was developed in LabVIEW software from National Instruments. The results were obtained through the observation of the network s behavior of sensors proposal, focusing on aspects such as: indoor and outdoor quantity of packages received and lost, general aspects of reliability in data transmission, coexistence with other types of wireless networks and power consumption under different operating conditions. The results were considered satisfactory, which showed the software efficiency in this communication system

Análise de desempenho de estratégias de retransmissão para o mecanismo HCCA do padrão de redes sem fio IEEE 802.11e

This paper presents the performanee analysis of traffie retransmission algorithms pro¬posed to the HCCA medium aeeess meehanism of IEEE 802.11 e standard applied to industrial environmen1. Due to the nature of this kind of environment, whieh has eleetro¬magnetic interferenee, and the wireless medium of IEEE 802.11 standard, suseeptible to such interferenee, plus the lack of retransmission meehanisms, refers to an impraetieable situation to ensure quality of service for real-time traffic, to whieh the IEEE 802.11 e stan¬dard is proposed and this environment requires. Thus, to solve this problem, this paper proposes a new approach that involves the ereation and evaluation of retransmission al-gorithms in order to ensure a levei of robustness, reliability and quality of serviee to the wireless communication in such environments. Thus, according to this approaeh, if there is a transmission error, the traffie scheduler is able to manage retransmissions to reeo¬ver data 10s1. The evaluation of the proposed approaeh is performed through simulations, where the retransmission algorithms are applied to different seenarios, whieh are abstrae¬tions of an industrial environment, and the results are obtained by using an own-developed network simulator and compared with eaeh other to assess whieh of the algorithms has better performanee in a pre-defined applieation

Wireless sensor networks are reality nowadays. The growing necessity of connectivity between existing industrial plant equipments pushes the research and development of several technologies. The IEEE 802.15.4 LR-WPAN comes as a low-cost and powersaving viable solution, which are important concerns while making decisions on remote sensoring projects. This study intends to propose a wireless communication system which makes possible the monitoring of analogic and/or digital variables (i. e., the pressure studied) involved on the artificial methods for oil and gas lifting. The main issues are: To develop a software based on SMAC Standard in order to create a wireless network to monitoring analogic and/or digital variables; To evaluate the communication link based on the number of lost packets tested in different environments (indoor and outdoor) and To propose an instrumentation system consisting of wireless devices

Jambolão (Syzygium cumini) desidratado por liofilização e secagem em leito de jorro: avaliação do impacto do processo de secagem e caracterização do potencial funcional do produto final

Tropical fruits have been extensively studied due to their functional potential attributed to the presence of natural bioactive compounds. The exotic fruit jambolan (Syzygium cumini) has been reported for its appreciable amount of phenolic compounds, especially anthocyanins and antioxidant capacity. Nevertheless, there are hardly any derived jambolan products in the Brazilian market. In addition to that, considerable volumes of fruit are lost due to their high perishability. Dried fruits have become an important fruit market segment due to its weight and volume reduction and decreased transportation and storage costs. Thus, this study evaluated the jambolan pulp submitted to spouted bed drying (JLJ) and lyophilization (JLI), besides assessing the drying impact on the final product. In order to achieve this, the process performance was calculated and compared, as well the physicochemical and bioactive characteristics (moisture, water activity (aw), solubility, hygroscopicity, density, color, structure through images obtained by scanning electron microscopy (SEM), concentration of bioactive (total phenolic compounds (TPC), anthocyanins, proanthocyanidins and ascorbic acid) and antioxidant activity. The results showed drying efficiency higher than 60% for both products and that JLJ group showed higher moisture and water activity when compared to the JLI group (p<0.05). The two types of drying were able to produce stable final product in the microbiological point of view, given that both showed aw < 0.6. The final products exhibited high solubility (73.7 to 81.6%) and low hygroscopicity (9.8 to 11.6%), desirable characteristics for dehydrated foods. Despite the losses caused by drying, the dried jambolan pulp by both methods showed high TPC (468.6 to 534.0 mg GAE/100g dm), anthocyanins (from 491.9 to 673.4 mg. eq. cyanidin-3-glicoside/100g dm), proanthocyanidins (66.9 to 76.6 mg QTE/g dm) and ascorbic acid (156.4 to 186.8 mg/100 g dm). Taken together, the results of this study reveal spouted dried and freeze dried jambolan pulp as bioactive-rich natural products with suitable physicochemical and functional characteristics to be used as food ingredients. The data also demonstrate the drying techniques as rational strategies for the exploitation of the exotic fruit jambolan

Cinge a musa o oráculo da tradição: revelações perenes da narrativa em contos de Perrault

Le présent ouvrage comprend des versions comparatives de neuf contes de Perrault, parmi les plus célèbres, publiés dans des éditions intégrales, au Brésil, entre 1934 et 2005. L analyse comparative donne la priorité à l identification des éléments relatifs à l oralité, comme ceux qui appartiennent, selon Ong (1998) et Havelock (1996), à des contextes de cultures antérieures à l épanouissement de l écriture et qui donc élaboraient ses propres structures de pensée et d expression pour interagir dans la vie pratique comme dans la création, dans la transmission et la manutention des coutumes et traditions. Issus des premiers récits, les contes de Perrault, traduits ou adaptés au Brésil, gardent en eux l esprit du langage narratif auquel l auteur français a consagré une attention spéciale, pour transposer dans l écrit quelques récits de la grande expérience humaine née dans le milieu populaire et qui désormais intègrent l espace de l écriture à chaque nouvelle version produite. Les bagages formulaires, comme les épithètes, les interventions du narrateur et la propre relation des signifations de l intrigue avec les structures de l imaginaire toujours présentes dans l humanité, démontrent le rapprochement entre l oralité et écriture. En suivant les discussions théoriques de Zumthor (1993, 1997, 2000) et par l interation du lecteur avec le texte, on constate que ces éléments relatifs à l oralité rendent possibl existence d une performance dans l écrit a partir des impressions cinesthésiques qui chaque lecture provoque chez le lecteur et récepteur d un texte narratif qui revendique, automatiquement, la construction d une ouvrage seulement possible à chaque instant de l interation, par le processus esthétique de la réception. Même au niveau d écrit, ou l intensité de sa présence est diminuée en raison de l absence d un corps physique qui transmet, qui développe, qui opere littéralement le texte par la voix et qui réunit l écoute et la vision de l auditeur, la performance produite s interpose entre le corps du lecteur qui agit sur le texte et en même temps reçoit les sensations lui permettant l expérience esthétique. Ainsi, dans l expérience de la lecture de Contes de Perrault est possible percevoir les éléments qui renvoient à la forme du conte de tradition populaire. Même déjà influencée par l écrit, le lecteur peut identifier, dans cette oeuvre, les possibilités determinantes de la dynamique perpétuel dans la transmission de ses textes: le plaisir de la pratique de l écoute des histoires contées oralement et le plaisir de la pratique de lectures silencieuses et solitaires. Dans ce chemin le lecteur devoit chercher les sens perdus, ici, rencontrés avec l aide des discours littéraires, linguistique, folklorique, anthropologique et psycanalytique sur la surface du texte narratif merveilleux. Outre cela, ces discours collaborent avec le lecteur qui retrouvent les voix emprisonnées par l écrit dans la virtualité et dans émergence d une performance

Impacto do Programa de Saúde da Família sobre indicadores de saúde bucal na população de Natal -RN

The aim of this study was to assess the impact of the Family Health Program (FHP) on a number of oral health indicators in the population of Natal, Brazil. The study is characterized as a quasi-random community intervention trial. The intervention is represented by the implementation of an Oral Health Team (OHT) in the FHP prior to the study. A total of 15 sectors covered by the FHP with OHT were randomly drawn and paired with another 15 sectors, based on socioeconomic criteria, not covered by the teams. A few sectors were lost over the course of the study, resulting in a final number of 22 sectors, 11 covered and 11 not covered. We divided the non-covered areas into two conditions, one in which we considered areas that had some type of assistance program such as the Community Agents Program (CAP), FHP without OHT, BHU (Basic Health Unit) or no assistance, and the other, in which we considered areas that had only BHU or no assistance. Community Health Agents (CHAs) and Dental Office Assistants (DOAs) applied a questionnaire-interview to the most qualified individual of the household and the data obtained per household were transformed into the individual data of 7186 persons. The results show no statistical difference between the oral health outcomes analyzed in the areas covered by OHT in the FHP and in non-covered areas that have some type of assistance program, with a number of indicators showing better conditions in the non-covered areas. When we considered the association between covered and non-covered areas under the second condition, we found a statistical difference in the coverage indicators. Better conditions were found in covered areas for indicators such as I have not been to the dentist in the last year with p < 0.001 and OR of 1.64 and I had no access to dental care with p < 0.001 and OR of 2.22. However, the results show no impact of FHP with OHT on preventive action indicators under both non-covered conditions. This can be clearly seen when we analyze the toothache variable, which showed no significant difference between covered and non-covered areas. This variable is one of the most sensitive when assessing oral health programs, with p of 0.430 under condition 1 and p of 0.038 under condition 2, with CI = 0.70-0.90. In the analysis of health indicators in children where the proportion of deaths in children under age 1, the rate of hospitalization for ARI (Acute Respiratory Infections) in those under age 5 and the proportion of individuals born underweight were considered, a better condition was found in all the outcomes for areas with FHP. Therefore, we can conclude that oral health in the FHP has little effect on oral health indicators, even though the strategy improves the general health conditions of the population, as, for example child health

Relação das condições socioeconômicas com as condições de saúde bucal em capitais brasileiras

Despite the improvement of Brazilian s living conditions in recent decades, this improvement occurred in a polarized way between groups of better social position. Then, there is still a health inequity´s panorama in Brazil which encompasses the oral health state. This panorama instigated the attainment of this ecological study that aimed to evaluate the relationship of socioeconomic conditions, and public health policies with oral health status in Brazilian capitals. Thus, we performed factor analysis and linear regression using oral health indicators collected from SB Brasil 2010, of socioeconomic conditions from Brazilian Census 2010 and related to water´s supply fluoridation from SISAGUA. Factor analysis with indicators of living conditions revealed two common factors, economic deprivation and socio-sanitary condition. Economic deprivation showed statistically significant positive correlation with DMFT 12 years (p= 0,03) and mean missing teeth (p = 0,002) and negative correlation with caries-free population (p=0,012). Socio-sanitary negatively correlated with DMFT (p <0,0001) and a positive correlation with caries-free population (p = 0.002). Fluoridated water had a significant association with DMFT (p <0,0001), mean missing teeth (p <0,0001) and caries free population (p <0.0001). Multiple linear regression analysis for the DMFT of capital was estimated by socio-sanitary condition and fluoridation, adjusted by economic deprivation, whereas the model for the mean missing teeth was estimated only by fluoridation and economic deprivation, and finally the model the rate for the population free of caries in Brazilian capitals was estimated by economic and socio-sanitary status adjusted fluoridated water supply. Therefore, factors related to living conditions and public policies are intrinsically linked to tooth decay issues. Thus, actions, beyond dental care assistance, must be development to impact positively in social and economic conditions, especially, between the most vulnerable populations

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

Nostalgia do espaço e do tempo: uma leitura da obra memorialística de Câmara Cascudo

This dissertation addresses the work of the memoirs of the potiguar writer Luís da Câmara Cascudo (1898 - 1986) from an integrated reading of four works that comprise: O Tempo e Eu (1968), Pequeno Manual do Doente Aprendiz (1969), Na Ronda do Tempo (1971) and Ontem (1972). Produced under the contingency of the modern movement and urban reform, memories Cascudo evoke the old landscapes of old, populated by those who belonged to the old romantic and provincial Natal that no longer exists, but which still survives in the idealized memory author and that is (re)constructed by him from a written permeated with touches of imagination and a sense of nostalgia. Seeking to analyze how is the process of building memoirist of Cascudo, as well as reflect on the role that memory plays in the (re)construction of a time and a lost space, we used the studies of Maurice Halbwachs (2006) and Ecléa Bosi (1994). Within this theoretical framework, we seek, above all, to understand not only how the lived experiences of Cascudo will work in this matter of his memory, but also as this will guide a writing that touches on the history and social frameworks of the past

Geração de padrão de marcha adaptável para uma órtese ativa de membros inferiores

Atualmente com o crescente aumento de dispositivos robóticos destinados para aplicação na área de mobilidade de pessoas que sofreram algum tipo de lesão medular, se faz necessário desenvolver novas ferramentas para tornar tais equipamentos mais adaptáveis, seguros e autônomos. Para que as órteses robóticas que auxiliam na locomoção de pessoas paraplégicas possam desempenhar sua função, estas devem ser capazes de reproduzir os movimentos perdidos com o máximo de fidelidade e segurança em ambientes que eventualmente possam conter obstáculos de diferentes tipos como buracos, escadas e calçadas. As órteses robóticas para membros inferiores têm a capacidade de caminhar, subir e descer degraus, todavia, esses movimentos, na maioria das vezes, não se adaptam ao ambiente, sendo assim, para uma órtese robótica que foi projetada para subir um degrau com uma determinada altura ao se deparar com um degrau maior provavelmente não conseguirá realizar essa tarefa com a mesma segurança. Para solucionar esse e outros problemas, esse trabalho apresenta um Sistema de Auxílio à Locomoção (SAL) dotado de um planejador de passos e um gerador de referências angulares com características antropomórficas para a órtese robótica Ortholeg. O SAL utiliza dados antropométricos do usuário para gerar um padrão de marcha personalizado, dessa forma, a órtese em questão é capaz de adaptar o tamanho do passo para não colidir com obstáculos presentes no ambiente e transpor buracos com diversos tamanhos, subir e descer escadas e calçadas com diferentes valores de altura e comprimento. Para desenvolver o sistema de auxílio à locomoção foram adaptadas técnicas de planejamento de caminho, usadas a princípio em robôs bípedes. São apresentados vários experimentos que mostram a órtese Ortholeg realizando alguns movimentos com características antropomórficas para diferentes distâncias de caminhada e três tipos de obstáculos: degrau, buraco e calçada. A autonomia adquirida com a utilização do sistema de planejamento apresentado facilita a utilização de órteses robóticas como também garante uma maior segurança ao usuário.

Ações de promoção em saúde bucal: um estudo com o povo indígena Tremembé, CE

Este trabalho aborda ações de promoção em saúde desenvolcidas no Projeto de Saúde Bucal com Povo Indígena Tremembé, Ceará, viabilizadas por uma parceria da Igreja Metodista, Universidade Federal do Rio Grande do Norte (UFRN) e Universidade Metodista de Piracicaba (UNIMEP). Pretendeu contribuir para a melhoria na qualidade da saúde bucal Tremembé valorizando etnoconhecimentos e saúde integral. A atuação priorizou Ações de Educação e Saúde utilizando um Levantamento Epidemiológico para o diagnóstico situacional de cárie e planejamento, e contemplou o Atendimento Odontológico. Nas Ações de Educação em Saúde utilizou-se a pedagogia da problematização através de Oficinas de Preservação em Saúde resultando na produção da Cartilha de Saúde Bucal Tremembé. Os dados epidemiológicos, com 102 indivíduos, obtidos através do índice CPO-D (dentes permanentes cariados, perdidos e obturados) foram organizados pelo programa Epi Info 6.04, em 4 grupos etários (até 24; 25-34; 35-44; 45›) resultando em médias que variaram de 9,5 a 20,9 respectivamente, evidenciando precária situação de saúde bucal. As ações de promoção em saúde contribuíram para consciência sanitária, no sentido da reivindicação dos direitos à saúde representada como um exercício da cidadania, bem como na busca pela autonomia em relação à prevenção de doenças bucais entre os Tremembé.

Biologia reprodutiva de Mimus gilvus (Aves: Mimidae) em área de restinga no nordeste do Brasil

The thrush beach, Mimus gilvus (Aves: Mimidae) is a passerine widely distributed in Central and South America. In Brazil occurs mainly in the areas of the resting and vegetation near the beach. In southeastern Brazil this species has disappeared, mainly due to urbanization. Many attributes of their reproductive biology are unknown, especially in relation to reproductive success. During the years 2010-2011, 2011-2012 and 2014-2015 were made visits to the area of restinga forest in Centro de Lançamento da Barreira do Inferno (CLBI), located between the cities of Natal and Parnamirim-RN (5 ° 54'S 35 ° 10'W ) where they were made systematic searches to trying describe reproductive biology of the characteristics of M. gilvus, estimate their reproductive success using the Mayfield method, and identify the main factors that influence their reproductive success in environment the resting. For this, forty fifth active nests monitored were used. Only during the breeding season of 2011-2012 and 2014-2015 were made systematic visits to the study area. The reproductive period ranged August to March. Clutch size ranged from two, three and six eggs (n = 22). Broods of two eggs were more common, with an average of eggs laid per nest of 2 ± 0,51 (n = 20 nests). The incubation period was approximately 13 ± 1,9 days (n = 11 nests). The period of stay of the nestlings was approximately 11 ± 1,6 days (n = 9 nests). With approximately 11 days old the nestlings were able to leave the nest. The apparent success was 37,8% and the success estimated by Mayfield method was 26,6%. Predation was the main cause of loss of nests in the study area. The daily survival rates (TDS) were obtained from 0,9593 incubation and 0,9313 for nestling period respectively. Survival estimates for each period was 0,5827 for incubation and 0,4571 for nestling period. The cumulative average rainfall for each month influenced negatively the hatching rates of M. gilvus nests. In addition, the number hatch eggs among the most rainy season (rainy season) and the period of lowest rainfall (dry season) were different. The number of lost nests of M. gilvus was lower in scrubs than cactus, which may account for the largest number of nests of this species found in scrubs. Survival rates in nestling period were lower compared with the incubation period. The fact that the survival rates nests of M. gilvus be lower in the nestling period compared to the incubation period may result from increased activity of adults during this phase of the nest, which in turn would increase predation rates. M. gilvus seems to avoid the rainy season during their reproduction, concentrated most of their nests in periods of low rainfall.
