Nutrição da gestante portadora de anemia falciforme, complicações maternas e resultados perinatais

O prognóstico da gestação é influenciado pelo estado nutricional materno. Sabe-se que, desde a infância, as pessoas portadoras da doença falciforme apresentam crescimento deficiente. Pouco se conhece sobre a evolução do estado nutricional materno na anemia falciforme. O objetivo foi analisar o estado nutricional de gestantes portadoras de anemia falciforme, avaliando o ganho de peso, o consumo dietético materno e os resultados adversos maternos e perinatais. Métodos: Foram avaliadas 26 gestantes portadoras de anemia falciforme SS e 23 SC, a partir do início do pré-natal especializado até o puerpério. Como grupo controle foram utilizadas 63 gestantes, sem comorbidades. O estado nutricional das gestantes foi avaliado de acordo com índice de massa corporal, pré-gestacional e ao final da gravidez, bem como analisado o ganho de peso materno. O consumo dietético foi analisado utilizando-se questionário de frequência alimentar, em cada trimestre, caracterizando-se o valor energético total e a ingestão de macronutrientes e micronutrientes. As complicações maternas e perinatais foram investigadas. O nível de significância foi 0,05 (alfa=5%). Resultados: O IMC pré-gestacional foi significativamente menor no grupo SS (mediana 20,3 kg/m2) quando comparado com os grupos SC (22,7 kg/m2, p < 0,05) e controle (23,2 kg/m2, p < 0,05). O baixo peso pré-gestacional (IMC < 18,5 kg/m2) foi significativamente mais frequente no grupo SS (15,4%) quando comparado aos grupos SC (4,4%) e controle (1,6%, p=0,009). Ao final da gestação, o grupo SS apresentou menor IMC (mediana 23,1 kg/m2) quando comparado com o grupo SC (26,1 kg/m2, p < 0,05) e controle (28,5 kg/m2, p < 0,05). O ganho ponderal na gestação foi menor no grupo SS (mediana 8,0 kg) quando comparado com o grupo SC (11,9 kg, p < 0,05) e Controle (13,7 kg, p < 0,05). Na análise do consumo dietético no 2º trimestre, constatou-se que os grupos SS e SC apresentaram menor consumo de proteínas (medianas, 73 g/d e 69 g/d) quando comparados aos controles (96 g/d, p < 0,05); e o consumo de cálcio foi menor no grupo SS comparado ao controle (mediana, 410 vs. 748 g/d, p<0,05). No 3º trimestre, houve menor consumo de proteínas pelo grupo SS quando comparado com os controles (mediana, 68 g/d vs. 93 g/d, p < 0,05); o consumo de vitamina A foi menor no grupo SS quando comparado aos controles (mediana, 447 vs. 940 mcg/d, p < 0,05); o consumo de vitamina E foi menor no grupo SS (mediana, 6 mg/d) quando comparado aos grupos SC (10 mg/d) e controle (7 mg/d, p < 0,05). As complicações maternas mais frequentes foram: crise álgica, 58% no grupo SS e 44% no SC (p=NS); infecção urinária, 31% no SS e 17% no SC (p=NS); e infecção pulmonar, 35% no SS e 9% no SC (p=NS). Houve diferença significativa no diagnóstico de sofrimento fetal: SS (36%), SC (14%) e controle (13%, p=0,032). Resultados perinatais adversos foram mais frequentes nos grupos SS e SC quando comparados aos controles. Conclusões: O estado nutricional das gestantes portadoras de doença falciforme SS caracterizou-se pela desnutrição materna, com baixo ganho ponderal na gestação. O consumo dietético de macronutrientes demonstrou ingestão inadequada de proteínas nos 2º e 3º trimestres. As complicações maternas e resultados perinatais adversos foram eventos frequentes nas gestantes portadoras de doença falciforme

O ensino da comunicação na formação universitária em ciências da Nutrição: momento atual e sua evolução até aos dias de hoje

O percurso da crescente integração das ciências da comunicação no ensino das Ciências da Nutrição reflete a importância de dotar os nutricionistas de competências comunicacionais capazes de influenciar os comportamentos dos indivíduos e populações para escolhas alimentares mais conscientes e saudáveis. O presente texto pretende contextualizar a evolução da integração da área das ciências da comunicação no ensino das Ciências da Nutrição, tendo como caso de estudo as unidades curriculares de Comunicação e de Projeto de Comunicação, do 1º ciclo de estudos em Ciências da Nutrição da FCNAUP. Estas duas unidades curriculares, no âmbito das ciências da comunicação, são complementares, atuando de forma concertada. Face aos atuais desafios da comunicação na área da nutrição, as metodologias de ensino utilizadas nestas unidades curriculares têm procurado promover a realização de atividades pedagógicas muito diversificadas e em contexto real. Pretende-se que os futuros nutricionistas sejam capazes de utilizar formatos de comunicação e modelos de educação alimentar inovadores e, ao mesmo tempo, apelativos, com o objetivo final de tornarem a sua intervenção cada vez mais eficaz do ponto de vista da tomada de consciência para a mudança de comportamentos alimentares por parte da população.

A CONSTRUÇÃO DE UM DISCURSO SOBRE NUTRIÇÃO E SAÚDE CARDIOVASCULAR: ANÁLISE DA REVISTA SAÚDE É VITAL

A educação em saúde é um tema que requer atenção de todos. O cenário atual da qualidade de saúde da população nos convida a refletir sobre mudanças que visem a construir um panorama mais saudável. Conhecer a trajetória que o alimento, o corpo e a saúde percorreram no decorrer da história nos remete a necessidade de compreender as representações socioeconômicas e culturais que estes conquistaram e como se tornaram mercadorias altamente vendáveis e que despertam o desejo na sociedade de consumidores. Este trabalho tem por objetivo analisar as estratégias discursivas utilizadas nos textos publicados na seção nutrição da Revista Saúde é Vital, cuja temática seja nutrição e doenças cardiovasculares, no sentido de buscar entender como esse discurso construído pode contribuir com o processo de educação nutricional da população. Por meio da análise do discurso da missão, carta ao leitor, capas das revistas, índices de objetividade e subjetividade presentes nas matérias selecionadas constatou-se que as estratégias discursivas contribuem com o processo educativo. No entanto, para que a educação nutricional seja sólida faz-se necessário que o conhecimento não seja fragmentado. Educar não é informar. Educar é ensinar a pensar. Pensar não é ter as informações. Pensar é o que se faz com as informações.

Diagnósticos de enfermagem do domínio nutrição em pacientes submetidos à hemodiálise

The study aimed to analyze the nursing diagnoses of the nutrition domain from NANDA International in patients undergoing hemodialysis. This is a transversal study conducted in a university hospital in northeastern Brazil, with 50 hemodialysis patients. The data collection instrument was an interview form and a physical examination, in digital format, applied between the months of December 2013 to May 2014. Data analysis was divided into two stages. In the first, defining characteristics, related factors and risk factors were judged as to their presence by the researcher, according to the data collected. In the second stage, based on data from the first, diagnostic inference by experts was held. The results were organized in tables and analyzed using descriptive and inferential statistics for the diagnoses that showed higher frequencies than 50%. The project was approved by the Ethics Committee responsible for the research institution (protocol number 392 535), with Certificate Presentation to Ethics Assessment 18710613.4.00005537 number. The results indicate a median of 7 (± 1.51) nursing diagnoses of the nutrition domain per patient. Six diagnoses with greater frequency than 50% were identified, namely: Risk for electrolyte imbalance, Risk for unstable blood glucose level, Excess fluid volume, Readiness for enhanced fluid balance, Readiness for enhanced nutrition and Risk for deficient fluid volume. The defining characteristics, related and risk factors presented an average of 34.78 (± 6.86), 15.50 (± 3.40) and a median of 4 (± 1.93), respectively, and 11 of these components had statistically significant association with the respective diagnoses. Were identified associations between adventitious breath sounds, edema and pulmonary congestion with the diagnosis Excess fluid volume; Expressed desire to increase fluid balance with the nursing diagnosis Readiness for enhanced fluid balance; It feeds regularly, Attitude to food consistent with the health goals, Consume adequate food, expresses knowledge about healthy food choices, expresses desire to improve nutrition, expresses knowledge about liquid healthier choices and following appropriate standard supply with diagnosis Readiness for enhanced nutrition. It is concluded that the diagnosis of the nutrition domain related to electrolyte problems are prevalent in customer submitted to hemodialysis. The identification of these diagnoses contributes to the development of a plan of care targeted to the needs of these clients, providing better quality of life and advance in the practice of care

Riscos à saúde dos trabalhadores em unidade de alimentação e nutrição de um Hospital Universitário

The Food and Nutrition Units (FNU) are designed to produce food for healthy and/or sick communities and need to be done in a way to ensure the quality of foodstuffs that were produced. In these units, in the working environment, in general, there is excessive noise, heat and physical condition with many adaptations, presence of obstacles, inadequate flows, as well as the ways of the working organization may represent risks for workers health and lead to errors during production and/or distribution of food. The main goal of this study was to analyse the working processes in the Food Production Unit of the university’s hospital and identify the workers' health risk factors, using for this the knowledge of ergonomics, specifically the method of Ergonomic Work Analysis (EWA). After this analysis it was possible to develop proposals that will bring improvements to the working conditions, minimizing health risk factors during the process of meals production. It’s crucial to reassert this method considers the work activity performed in real time and highlights the importance of listening and the engagement of the workers in the changing process. It is a descriptive research with a qualitative approach. In the field research were collected demographics data, employment characteristics of the individuals (age, education, stocking sector, the total length of service and length of service in the industry) and data related to their usual work (task analysis, activity analysis and Analysis of the working environment) in the FNU. The instruments that were used in this study were document analysis, global and systematic observations and semi structured interviews in order to identify the main complaints related to those activities developed by them. The study was based on data for the analysis of Bardin, 2011, so the documents have been selected and including those that treat issues related to risks to workers' health were selected. The result of semi-structured interviews, global and systematic observations took place a confrontation of this material to the theoretical framework, held the inference and the interpretation of results the light of the knowledge of ergonomics and legislation. Issues related to the risks and the perception of workers has crafted a table showing the frequency of responses to the physical, chemical and biological and even the risk of accidents and was made a descriptive analysis. The results of this analysis indicated that the unit in question presents several problems ambience of jobs, both in terms of physical structure, but also in the organization of work. Non-conformities that leads to a favourable environment to the development of disease and injury hazards and compromising the quality of food produced. It is necessary to comply with legislation and that short, medium and long-term measures are taken to ensure the physical integrity of workers and improve the working environment.

Potencial do óleo de Aloysia citriodora Palau no controle de fitopatógenos e na indução de resistência ao tombamento de plântulas de feijão, pepino e beterraba

The crops are affected by pests and diseases that decrease productivity. Among them are the damping off of seedlings that can occur in pre and post-emergence. In bean crops, cucumber and beet these diseases occur, being caused by various pathogens, especialy fitopathogenic fungi. Several measures are used for the controle of such diseases, among them, is the chemical seed treatment fungicides. However, society has become increasingly concerned about the quality and food and environmental contamination, generation a growting search for sensitive products to humans and the environment. The use of essential oils to control plant pathogens is an example of alternative tested by science in the search for less aggressive technologies. This study aimed to evaluate the efficiency of the use of essential oil Aloysia citriodora, in control of pathogens causing damping off in beans, cucumber and beet. This thesis was divided in four chapters, the introductory first, and the other addressing the control of Pythium sp. in beans, Sclerotinia sclerotiorum on cucumber, and Fusarium sp. on beet. The methodology consisted of four experiments in each pathosystem, with all the work done at the Federal Technological University of Parana, Campus Dois Vizinhos. In the first experiment evaluated the fungistatic and fungicidal effect of the essential oil of A. citriodora on PDA in vitro in mycelial growth of pathogens studied. In the second experiment evaluated the in vitro effect of essential oil concentrations of A. citriodora in BD medium on microscope slides, on the germination of sporangia Pythium sp. and conidia Fusarium sp., and in Petri dishes with PDA medium, the sclerotia germination speed index of S. sclerotiorum. In the third experiment, we evaluated in germination test in paper roll (PR), the phytotoxic effect or not the use of essential oil concentrations of A. citriodora in dry bean seed, cucumber and beet. The variables used to assess this experiment were the germination percentage, mediun green mass per plant and average length of seedlings. In the fourth experiment we assessed the effect of treating bean seeds, cucumber and beet with essential oil contents of A. citriodora, seeds in their subsequent substrates contamined with pathogens studied, Pythium sp., S. sclerotiorum and Fusarium sp. In this experiment we used the following variables: percentage of emergence, percentage of post-emergence damping off, green average mass per plant, average length per plant and biochemical analyzes. The biochemistry of plant tissues evaluated were as follows: protein content, enzymatic activities of peroxidases, phenylalanine ammonia-liase (PAL), chitinases and β-1,3-glucanases. The in vitro results show that the essential oil has fungistatic and fungicidal effect on mycelial growth, on sporangia germination, conidia and sclerotia of the pathogens studied in this work, wich may be related to its major components, citral and limonene. The oil also exhibits low phytotoxicity to seeds of the species studied, only in beans decreases germination in most studied dosage (0,25%), cucumber also in the higher dosage (0,25%) reduce the length of seedlings, and beet there were no negative effects to the seedlings. In the test in substrate contaminated with the pathogens, the use of essential oil: increased germination and decreased post emergence damping off of beans seedlings; at a concentration of 0,0625% decreases post emergence damping off in cucumber. In biochemical analyzes found an increase in the enzymatic activity of peroxidases and β-1,3-glucanases on beans, and glucanases on cucumber, and increased enzyme activity of peroxidases on beet, showing action in resistance induction at damping off.

Chorume de suíno no controle da rizoctoniose em beterraba

The fungus Rhizoctonia solani is a soil borne pathogen that causes damage to various crops. The chemical control, when managed incorrectly, can be harmful to the environment, which makes the study of alternative control important. This study aimed to evaluate the ability of different doses of Liquid swine manure (LSM), with and without the retention of gases, at different soil pH levels, to control R. solani in beet. An inoculum of the fungus R. solani was on rice grains, which had been previously sterilised. The experiments were set up in a greenhouse in a completely randomised block design, arranged in a three-factor 2 x 2 x 5 scheme, comprising of soil pH levels (4.8 and 7.2) x with and without gas retention x LSM dose (0, 5, 10, 15 and 20%), with four replications per treatment. To setup the experiments, 4 kg of soil of each pH level were packed separately into plastic bags. Subsequently, the soil of each bag was infested with 15 g of fungus inoculum/kg of soil, and moistened as necessary. After seven days of infestation of the soil with the pathogen the different doses of LSM were incorporated separately into the bags, the bags designated as the gas retention treatment were closed, while those designated as the gas release treatment were left open. After seven days, part of the soil from each bag was packed separately into 16 cells of 128 cell Styrofoam trays, which were then seeded with two beet seeds per cell. The other part of the soil was placed in 2 litre pots, to conduct the quantification of microbial activity, through the method of CO2 release, 21 days after the experiment was setup. Seedling emergence and damping-off evaluations were performed daily for 21 days consecutively. The data was submitted to analysis of variance, and when significant were submitted to regression analysis or Tukey at 5% probability of error. The experiments were repeated twice. According to the results obtained, there was a suppressive effect of LSM on R. solani. For the variable emergence, the 10% dose of LSM resulted in the largest number of emerging plants in the two soil pH levels studied, whether or not gas was retained. Seedling dampingoff decreased with increasing volumes of LSM incorporated into the soil. The soil with the pH level of 7.2 presented less seedling damping-off than the soil with a pH level of 4.8. The retention of gases provided greater control of R. solani in the higher LSM doses and in soil with a pH level of 7.2. Also noted in this study that there was a significant increase in microbial activity with increasing doses of LSM when applied to soil with pH levels of 4.8 and 7.2. Based on these results, it was concluded that the 10% dose of LSM provided the best control of R. solani without harming seedling emergence.
