Acidentes de Trabalho : análise em profissionais de enfermagem que atuam nas unidades de terapia intensiva e urgência Natal/RN

It is a descriptive-exploratory research, with a quantitative approach, aiming to characterize typical occupational accident suffered by the professionals from nursery group, in the Intensive Care Units and Emergency in a hospital in Natal-RN, trying to identify the factors that contribute to those accidents; to identify some information taken by those professionals related to the accident risks; to know the procedures taken after each accident. This sample is composed by 176 professionals that are 44 nurses and 132 nursing technicians/auxiliaries, collected from March to April 2010. The results related to the personal characterization of the nursery group showed that 31 (18.61%) are between the 36-40 years of age; 148 (84.09%) females and 96 (55.68%) had finished High School. Related to the professional characterization, 53 (30.11%) are nurses, and 123 (69.88%) nursing technicians and auxiliaries; 44 (25.00%) are working as nurses, and 132 (75.00%) as nursing technicians and auxiliaries; 45 (25.56%) are working in the nursery area between 15 to 20 years and 11 months; 53 (30.11%) are in this institution between 10 to 14 years and 11 months; 79 (44.88%) work in the ICU; 55 (31.25%) are working in this area from 1 to 4 years and 11 months; 110 (62.50%) like to work in this area; 161 (91.47%) work 30 to 40 hours per week; 90 (51,13%) have another employment. Related to knowledge about typical occupational accident, 167 (94.88%) said they know about it; 96 (54.54%) know the accident rules; 103 (58.52%) think it is important to talk about this subject in the nursery courses; 92 (52.27%) said this subject is important to be discussed in the work and 372 (87.73%) think education is necessary to reduce accident. Related to the data about accidents, 104 (59.09%) have suffered typical occupational accident, among them 69 (39.20%) have suffered it once; 47 (36.19%) did not register any accident; 60 (57.69%) were caring some patient during the accident; 47 (45.19%) of them occurred in the ICU; 50 (48.07%) professionals were working during the night period; 69 (66.34%) have suffered perforation; 86 (82.69%) had upper limbs affected; 64 (61.53%) were affected by needle; about the reason of the accident, 89 (60.54%) said it occurred due to carelessness. Related to the accident evolution, 88 (85.57%) did not need to remain off work after accident; 13 (81.25%) remained off work during 15 days; 87 (83.65%) had no sequelae and for 101 (97.11%) it was not necessary rehabilitation. We conclude that typical occupational accident can occur with young workers who admit a knowledge about the subject, however they do almost nothing to prevent it. We believe this research has contributed to the characterization of this kind of accident suffered by the nursery group of a public hospital in Natal, and it can stimulate the creation and reformulation of personal protection against typical occupational accident suffered by nursery professionals

Parâmetros genéticos para diferentes relações de peso ao nascer e à desmama em vacas da raça Nelore

O presente estudo foi desenvolvido com o objetivo de estimar herdabilidade e repetibilidade para diferentes medidas de eficiência produtiva de vacas e determinar a melhor maneira de calcular as relações de peso, visando a sua utilização como critério de seleção em rebanhos da raça Nelore. Os dados analisados são de animais da raça Nelore, pertencentes ao Projeto de Seleção das Raças Zebuínas e Caracu do Centro APTA Bovinos de Corte, do Instituto de Zootecnia de Sertãozinho. Os animais são selecionados para maior peso ao sobreano (rebanhos NeS e NeT, analisados como um único rebanho) e para peso ao sobreano próximo da média (NeC) do grupo de contemporâneos, desde 1980. As características utilizadas no estudo foram: 1) RPN = relação de peso ao nascer do bezerro / peso da vaca ao parto; 2) RPN2 = relação do peso ao nascer do bezerro / peso metabólico da vaca ao parto; 3) RPD = relação de peso à desmama do bezerro / peso da vaca à desmama; e 4) RPD2 = relação do peso à desmama do bezerro / peso metabólico da vaca à desmama. Os parâmetros genéticos foram estimados considerando dois arquivos: vacas com bezerros (CB) e vacas com e sem bezerros (SB). A RPN e a RPN2 foram calculadas somente no arquivo CB, enquanto que RPD e RPD2 foram calculadas em ambos os arquivos (CB e SB). Os parâmetros genéticos foram estimados pelo método da máxima verossimilhança restrita. As estimativas de herdabilidade para as características RPN; RPN2; RPD_CB; RPD2_CB; RPD_SB e RPD2_SB foram: 0,17±0,02; 0,16±0,02; 0,22±0,04; 0,19±0,03; 0,20±0,01 e 0,16±0,01, respectivamente. As repetibilidades estimadas variaram de 0,22 a 0,68. A utilização das relações de peso como critério de seleção deve promover, a longo prazo, melhorias na eficiência produtiva das vacas. As relações de peso têm sido consideradas apenas como informações para o descarte de vacas em alguns programas de seleção, mas poderiam ser incluídas em índices de seleção, principalmente quando calculada considerando o peso metabólico da vaca à desmama, incluindo tanto as vacas que desmamaram um bezerro, quanto aquelas que falharam em desmamar.

Aerofotos convencionais e imagens orbitais TM/LANDSAT no mapeamento morfopedológico em Santa Bárbara D'Oeste (SP)

Foram estudados, com o auxílio de fotografias aéreas, aspectos qualitativos e quantitativos do relevo e da rede de drenagem de solos de uma área de Santa Bárbara D'Oeste, SP. Esta região compreende 14.625 ha, onde foram selecionadas bacias hidrográficas de 3ª ordem de ramificação e amostras circulares de 5km². As unidades de mapeamento simples ou associações de solos são: Latossolo Vermelho Escuro, Podzólico, Litossolo + Podzólico, Terra Roxa Estruturada + Latossolo Roxo distrófico. Após a caracterização das feições fisiográficas, da área de ocorrência desses solos, foram realizados dois mapas morfopedológicos. No primeiro utilizou-se fotografias aéreas verticais pancromáticas na escala 1: 35.000 (data de 25/6/78) e no segundo imagens orbitais do sensor Thematic Mapper do LANDSAT-5, nas bandas 3, 4 e 5 e composição colorida 3/4/5 na escala 1: 100.000 (data de 12/9/91). As análises qualitativas e quantitativas do relevo (índice de declividade média) e rede de drenagem (densidade de drenagem, freqüência de rios, razão de textura) mostraram-se eficientes na diferenciação das unidades de solo estudadas, tanto em bacias hidrográficas como em amostras circulares. A utilização de fotografias aéreas, permitiu maior riqueza de detalhes na precisão dos limites das unidades de mapeamento e no maior número de unidades de mapeamento discriminadas em relação as imagens orbitais. A composição colorida 3/4/5 permitiu diferenciar os Latossolos argilosos dos Latossolos de textura média, assim como o Latossolo Húmico.

Força muscular respiratória, qualidade de vida e modulação autonômica da frequência cardíaca na distrofia miotônica

Background: The myotonic dystrophy (MD) is a multisystem neuromuscular disease that can affect the respiratory muscles and heart function, and cause impairment in quality of life. Objectives: Investigate the changes in respiratory muscle strength, health-related quality of life (HRQoL) and autonomic modulation heart rate (HR) in patients with MD. Methods: Twenty-three patients performed assessment of pulmonary function, sniff nasal inspiratory pressure (SNIP), the maximal inspiratory (MIP) and expiratory (MEP) pressure, and of HRQoL (SF-36 questionnaire). Of these patients, 17 underwent assessment of heart rate variability (HRV) at rest, in the supine and seated positions. Results: The values of respiratory muscle strength were 64, 70 and 80% of predicted for MEP, MIP, and SNIP, respectively. Significant differences were found in the SF-36 domains of physical functioning (58.7 ± 31,4 vs. 84.5 ± 23, p<0.01) and physical problems (43.4 ± 35.2 vs. 81.2 ± 34, p<0.001) when patients were compared with the reference values. Single linear regression analysis demonstrated that MIP explains 29% of the variance in physical functioning, 18% of physical problems and 20% of vitality. The HRV showed that from supine position to seated, HF decreased (0.43 x 0.30), and LF (0.57 x 0.70) and the LF/HF ratio (1.28 x 2.22) increased (p< 0.05). Compared to healthy persons, LF was lower in both male patients (2.68 x 2.99) and women (2.31 x 2.79) (p< 0.05). LF / HF ratio and LF were higher in men (5.52 x 1.5 and 0.8 x 0.6, p <0.05) and AF in women (0.43 x 0.21) (p< 0.05). There was positive correlation between the time of diagnosis and LF / HF ratio (r = 0.7, p <0.01). Conclusions: The expiratory muscle strength was reduced. The HRQoL was more impaired on the physical aspects and partly influenced by changes in inspiratory muscle strength. The HRV showed that may be sympathetic dysfunction in autonomic modulation of HR, although with normal adjustment of autonomic modulation during the change of posture. The parasympathetic modulation is higher in female patients and sympathetic tends to increase in patients with longer diagnosis

Hipossalivação e seus fatores de risco em idosos funcionalmente independentes e não institucionalizados

The aim of this study was to investigate the risk factors related to hyposalivation among non-institutionalized independently living elderly people, living in Natal-RN, Brazil. The study was a control-case type and the data collection was accomplished by carrying a questionnaire, oral examination and a non-stimulated and stimulated sialometry. The cases were identified by values of salivary flow rate <0,1mL/min and stimulated ≤ 0,5 mL/min, and the controls were by observing the values of sialometry that were bigger than the previously defined parameters. Age and gender were used as pairing variables. The data were analyzed using X2 (α = 0,05) and odds ratio. The sample was composed of 98,1% female and 1,9% male, with mean age 68. There was not association between hyposalivation and the following studied variables: income, schooling, profession, dwelling conditions, domiciliary density, illness, number of teeth and use of prothesis. However, a link was found between hyposalivation and smoking frequency in the passet (OR=5,14), indicating that, referring to elderly people, the tabagism frequency habit was a risk factor to the studied condition. Therefore, refering to non-institutionalized independently elderly people, economic-social-demographic conditions, general and bucal health, diet and habits such as alcoholism have been not risk factors to hyposalivation. However, people that have been smoking have more risk to have the studied conditions

Relação entre a doença periodontal e doença cardiovascular: há uma preocupação por parte dos que fazem clínica médica e odontológica na cidade de Natal?

The relationship between periodontal and cardiovascular diseases is a reality in the current days. The knowledge about the role of periodontal disease as a risk factor to cardiovascular disease from dentistry and physicians is very important to try to eliminate this risk factor. The aim of this work was to investigate, using a questionary, if physicians and dentistry are aware about this relationship and if they think that it is important. These forms were distributed in 4 groups: cardiologists (n=90), physicians from other specialist (POS) (n=110), periodontists (n=35) and dentistry from other specialist (DOE) (n=85). We had a loss off 32,4% of the total sample due to a lack of response of some professionals. Our results showed that all cardiologists, all dentists and 68,2% of POE said that they had gotten information about the relationship between periodontal and cardiovascular disease, and just 6 POS don t believe that this relationship can occur. When questioned if, even when a periodontal disease is diagnosed, there is a habit to treat or orient the patient for treatment, 29,5% of cardiologists answered no, 25,5% of POE also answered that they did not orient and only 1 DOE answered that he did not treat nor orient. All periodontists said that treat their patients when periodontal disease was identify. The physicians seem not to find important the relationship that exist between periodontal and cardiovascular diseases and the dentistry have shown a good knowledge about this subject. Maybe, if physicians and dentistry work together, the incidence of cardiovascular disease decreases

O papel das relações sociais e da atenção social durante tarefas cooperativas em Callithrix jacchus

Several studies on nonhuman primates show that the relationships between individuals strongly influence the expression of cooperative behavior, both in natural environment and in captivity settings. Recent studies suggest that cooperative breeders present outstanding performance in tasks involving social cognition, such as cooperative tasks with experimental apparatuses. In experimental research on this subject it is crucial to differentiate between real cooperation (or communicative cooperation, mediated by social attention) and by-product cooperation that results from simultaneous actions of individuals. The present study assessed, in Callithrix jacchus, a cooperative breeder species, if social relationships and social attention between subjects are important factors during performance in cooperative tasks. During the experimental procedure the animals participated in three different cooperative tasks: cooperation task, prosocial task and control task. Diverging from the literature, matrix correlation tests revealed no significant relationship between grooming or proximity and the execution of the tasks, suggesting that other factors such as age or hierarchy may have an effect on the performance in cooperative tasks in this species. There was also no relationship between the execution of the cooperative tasks and social glances, suggesting that there was no social attention during the tasks. Moreover, there were lower rates of social glances in the cooperative tasks as opposed to the control tasks. However, the small number of pulls in prosocial tasks suggests that the animals distinguished between tasks that benefited only a partner and tasks that generated benefits to themselves, choosing the latter. We conclude that, for the tasks presented in this study, we could neither detect the role of social relationships on the cooperative tasks nor assert that there were true cooperation and prosocial behavior

Obtenção e aplicação de sistemas microemulsionados na recuperação avançada de petróleo

Due to the need of increasing production in reservoirs that are going through production decline, methods of advanced recovery have frequently been used in the last years, as the use of conventional methods has not been successful in solving the problem of oil drifting. In this work, the efficiency of different microemulsionated systems in the flow of oil from cores from Assu and Botucatu formations. Regarding drifting tests, cores were calcinated at a temperature of 1000°C, for 18 hours, with the aim of eliminating any organic compound present in it, increasing the resultant permeability. Following, the cores were isolated with resin, resulting in test specimens with the following dimensions: 3.8 cm of diameter and 8.7 cm of length. Cores were saturated with brine, composed of aqueous 2 wt % KCl, and oil from Guamaré treatment station (Petrobras/RN). A pressure of 20 psi was used in all tests. After core saturation, brine was injected again, followed by oil at constant flow rate. The system S3 - surfactant (anionic surfactant of short chain), isoamillic alcohol, pine oil, and water - presented the best drift efficiency, 81.18%, while the system S1E commercial surfactant, ethyl alcohol, pine oil, and distilled water presented low drift efficiency, 44,68%

Análise bromatológica de carnes antes e após o processamento para obtenção de charque

The process of salting and drying in the sun is used to preserve meat since the beginning of civilization. There is evidence that this preservation technique has arisen in Egypt, between 4,000 and 5,000 years ago. In our country, according to literature, was the first industrial product that gave the appearance of beef jerky, beef being produced, where about 70% to 75% of the muscle is composed of water, where it will be around 45% as a final product, according to the law in his article RIISPOA No. 432 provides that the jerky should contain no more than this amount of moisture in the muscular portion, or more than 15% of total ash with tolerance of up to 5% variation . Besides this parameter, proteins, lipids, ash, and minerals were analyzed in samples before and after the manufacturing process to know the content of these nutrients. Since these are considered important in product quality, thus the concentration in these samples, respectively, in the flesh Front (CD and CHD) before and after the manufacturing process for humidity were respectively 75.28% and 47.38% , the protein was 14.17 and 22.20 g / 100 g sample, 6.360 and 4.251 of lipids g/100g of the sample, and the ashes 0.974 9.144 g/100g sample, minerals like calcium and 4.074 30 , 06 ppm, sódio0, 055 and 5.401 g / L, sodium chloride, 0.139 and 13.74 g / L, potassium 237.5 and 166.8 ppm, 1.721 and 3.295 ppm iron, 0.143 and 0.135 ppm phosphorus, zinc and 4.690 6.905 ppm; magnésio14, 63 e13, 75 ppm manganese .017 e0, 007ppm, copper 0.057 and 0.039 ppm in the case of needle-type meat (CPA and CHPA), 68.04% and 44.17%, protein 13 , 72, and 24.42 g/100g of sample, 1.137 in the ash and 12.68 g / 100g of sample, and the minerals calcium 17.11 and 12.89 ppm; sódio0, 123 and 4.871 g / L, sodium chloride 0.312 and 12.39 g / L, potassium 305.3 and 182.1 ppm; ferro1, 817 and 1.513 ppm, 0.273 and 0.139 ppm phosphorus, zinc 6.305 and 4.783 ppm, 27.95 and 15.85 ppm magnesium, manganese and 0.025 0.011 ppm, 0.057 and 0.143 ppm copper and chromium 0.014 and 0.068 ppm

Tireóide ectópica cervical lateral: Relato de caso e revisão da literatura

Tireóide ectópica é qualquer tecido tireoideano localizado fora de sua topografia habitual, podendo apresentar-se na linha mediana do pescoço ou, mais raramente, na região cervical lateral. Algumas teorias tentam explicar a origem do tecido tireoideano ectópico: 1. falha na descida da glândula; 2. seqüestro de nódulos tireoideanos; 3. presença de tecido tireoideano na cápsula de linfonodos cervicais; 4. formação teratomatosa; 5. Secundário a anomalias branquiais. Na abordagem diagnóstica, diversos exames têm sido utilizados, sendo o diagnóstico definitivo algumas vezes fornecido apenas pelo estudo histopatológico. Apesar das controvérsias em relação às abordagens terapêuticas apresentadas na literatura, é necessário um planejamento rigoroso para evitar iatrogenias. Conclui-se que a presença de tecido tireoideano ectópico deve ser lembrada no diagnóstico diferencial de massas cervicais laterais, e sua origem histológica considerada, sendo na maioria das vezes metástase de um carcinoma tireoideano oculto. Os autores relatam um caso de tecido tireoideano ectópico lateral no pescoço, em paciente do sexo feminino com bócio colóide mergulhante. Foram realizadas considerações importantes sobre dismorfogênese tireoideana, métodos diagnósticos e opções de tratamento, com revisão da literatura das últimas cinco décadas.

Detecção de áreas degradadas na sub-bacia hidrográfica do rio taperoá/pb, utilizando parâmetros físicos dos sensores modis/terra e tm/landsat

This study includes the results of the analysis of areas susceptible to degradation by remote sensing in semi-arid region, which is a matter of concern and affects the whole population and the catalyst of this process occurs by the deforestation of the savanna and improper practices by the use of soil. The objective of this research is to use biophysical parameters of the MODIS / Terra and images TM/Landsat-5 to determine areas susceptible to degradation in semi-arid Paraiba. The study area is located in the central interior of Paraíba, in the sub-basin of the River Taperoá, with average annual rainfall below 400 mm and average annual temperature of 28 ° C. To draw up the map of vegetation were used TM/Landsat-5 images, specifically, the composition 5R4G3B colored, commonly used for mapping land use. This map was produced by unsupervised classification by maximum likelihood. The legend corresponds to the following targets: savanna vegetation sparse and dense, riparian vegetation and exposed soil. The biophysical parameters used in the MODIS were emissivity, albedo and vegetation index for NDVI (NDVI). The GIS computer programs used were Modis Reprojections Tools and System Information Processing Georeferenced (SPRING), which was set up and worked the bank of information from sensors MODIS and TM and ArcGIS software for making maps more customizable. Initially, we evaluated the behavior of the vegetation emissivity by adapting equation Bastiaanssen on NDVI for spatialize emissivity and observe changes during the year 2006. The albedo was used to view your percentage of increase in the periods December 2003 and 2004. The image sensor of Landsat TM were used for the month of December 2005, according to the availability of images and in periods of low emissivity. For these applications were made in language programs for GIS Algebraic Space (LEGAL), which is a routine programming SPRING, which allows you to perform various types of algebras of spatial data and maps. For the detection of areas susceptible to environmental degradation took into account the behavior of the emissivity of the savanna that showed seasonal coinciding with the rainy season, reaching a maximum emissivity in the months April to July and in the remaining months of a low emissivity . With the images of the albedo of December 2003 and 2004, it was verified the percentage increase, which allowed the generation of two distinct classes: areas with increased variation percentage of 1 to 11.6% and the percentage change in areas with less than 1 % albedo. It was then possible to generate the map of susceptibility to environmental degradation, with the intersection of the class of exposed soil with varying percentage of the albedo, resulting in classes susceptibility to environmental degradation

Leite cru de quatro regiões leiteiras brasileiras: perspectivas de atendimento dos requisitos microbiológicos estabelecidos pela Instrução Normativa 51

Evidências que o leite produzido e consumido no Brasil nem sempre apresenta a qualidade desejada têm gerado a discussão e desenvolvimento de novas políticas de incentivo à produção leiteira, resultando no desenvolvimento do Programa Nacional de Melhoria da Qualidade do Leite. em complementação, em 2002 o Ministério da Agricultura publicou a Instrução Normativa 51 (IN51), com importantes inovações em relação à conservação e transporte do leite cru, além de estabelecimento de um padrão de qualidade para esse tipo de leite (10(6) UFC/mL), a ser implantado em diferentes prazos nas diferentes regiões do país, a partir de 2005. O presente trabalho teve como objetivo verificar se o leite cru produzido em quatro áreas de quatro estados produtores de leite no Brasil estaria, nesse momento, em condições de cumprir o estabelecido na IN 51, especialmente quanto ao atendimento dos padrões microbiológicos previstos. Amostras de leite cru, coletadas em 210 diferentes propriedades nas regiões de Viçosa, MG (47), Pelotas, RS (50), Londrina, PR (63) e Botucatu, SP (50), foram analisadas quanto aos níveis de contaminação por aeróbios mesófilos, utilizando o PetrifilmTM AC. Parcela significativa das amostras (48,6%) apresentaram contagens acima do determinado pela IN51, sendo 21,3% na região de Viçosa (MG), 56,0% na região de Pelotas (RS), 47,6% na região de Londrina (PR) e 68,0% na região de Botucatu (SP). Considerando as diferenças de cada região, foi possível observar a importância da refrigeração na conservação e transporte da produção, bem como da implantação de boas práticas e assistência técnica nas propriedades. Os resultados obtidos permitem concluir que a adequação às normas estabelecidas pela IN51 pode ser mais difícil em algumas regiões do que em outras, sendo fundamental a adoção da refrigeração na conservação e no transporte da produção, e de programas regionais de assistência a produtores leiteiros.

A saúde na percepção do adolescente

Na fase da adolescência, o indivíduo experimenta os melhores índices de saúde, os quais podem ser mantidos e/ou melhorados, dependendo da percepção e valorização dos mesmos, influenciando na sua qualidade de vida. O estudo avaliou a opinião de adolescentes (n=493) da Fundação Mirim do Município de Araçatuba - SP, quanto à saúde geral e bucal, bem como sua percepção sobre elas, por meio questionário semiestruturado, durante o ano letivo de 2006, já que os mesmos possuem acesso à atenção à saúde bucal e palestras sobre saúde. Dentre os entrevistados 34,5% conceituaram a saúde como coisa ou algo que precisa(mos) cuidar; 26,6%, como bem-estar; 18,1%, como a própria existência; e 14,5%, como ausência de doença. em relação aos conceitos de saúde bucal, 68,4% definiram como higiene; 16,2%, como aparência; e 15,5%, como ausência de doenças bucais. A percepção desses jovens quanto a sua saúde em geral foi para 46,5%, ótima, e 44,1%, boa, enquanto que a da sua saúde bucal foi para 53,6%, boa, e 24%, ótima. Pode-se concluir que os adolescentes têm uma ideia tanto sobre saúde geral como saúde bucal, porém a classificação é menor no que tange à saúde bucal, pois envolve aspectos afetivos, estéticos e sociais. Ademais, percebe-se a necessidade de programas educativo-preventivos direcionados a esse grupo.
