Avaliação das indicações de ceratoplastia penetrante no interior paulista

Objective: To determinate the corneal diagnoses of patients underwent Penetrating Keratoplasty (PK) in the university hospital of Sao Jose do Rio Preto, São Paulo, Brazil, and their relation to age group, gender and socioeconomic factors. Methods: Retrospective analysis of 1085 registration forms of patients underwent Penetrating Keratoplasty in the university hospital of Sao Jose do Rio Preto, São Paulo, Brazil, from 2000 to 2009. The surgical indications were then correlated to age group, gender and socioeconomic factors, by chi-square test. Results: Fifty-seven percent of all Penetrating Keratoplasties were performed in male patients, and the mean age was 52.3 years. Most surgeries (90.8%) occurred by means of public health care (SUS). The main diagnosis was leukoma (23%), representing 14% of the indications for PK in males and 9% in females. Leukoma was also the diagnosis in 40% of PK performed in patients older than 60 years and in 94.4% of these surgeries in public health care users. Conclusion: The main indication for Penetrating Keratoplasty was leukoma, predominating in males, ages above 60 years and in public health care users.

Distribuição espacial de Alabama argillacea (Hübner) (Lepidoptera: Noctuidae) em algodoeiro

O conhecimento do modelo de distribuição espacial de pragas na cultura é fundamental para estabelecer um plano adequado de amostragem seqüencial e, assim, permitir a correta utilização das estratégias de controle e a otimização das técnicas de amostragem. Esta pesquisa objetivou estudar a distribuição espacial de lagartas de Alabama argillacea (Hübner) na cultura do algodoeiro, cultivar CNPA ITA-90. A coleta de dados ocorreu durante o ano agrícola de 1998/99 na Fazenda Itamarati Sul S.A., localizada no município de Ponta Porã, MS, em três diferentes áreas de 10.000 m² cada uma. Cada área amostral foi composta de 100 parcelas com 100 m² cada. Foi realizada semanalmente a contagem das lagartas pequenas, médias e grandes, encontradas em cinco plantas por parcela. Os índices de agregação (razão variância/média e índice de Morisita), o teste de qui-quadrado com o ajuste dos valores encontrados e esperados às distribuições teóricas de freqüência (Poisson, binomial positiva e binomial negativa), mostraram que todos os estádios das lagartas estão distribuídos de acordo com o modelo de distribuição contagiosa, ajustando-se ao padrão da Distribuição Binomial Negativa durante todo o período de infestação.

Effect of insulin-like growth factor-1 during in vitro oocyte maturation and in vitro culture of bovine embryos

Avaliaram-se o efeito do IGF-I na maturação in vitro (MIV) (experimento I) e no desenvolvimento embrionário (DE) (experimento II) de oócitos bovinos fecundados in vitro, quanto às taxas de clivagem (TC), de blastocistos (TB) e de eclosão (TE). Para MIV, complexos cumulus-oócitos imaturos foram cultivados em meio TCM-199 suplementado com HEPES, bicarbonato e piruvato de sódio, aditivos, soro fetal bovino (meio B-199) e gonadotrofinas 14U/ml de PMSG e 7U/ml de hCG). Para o desenvolvimento embrionário, os oócitos/zigotos foram cultivados em meio B-199 com células epiteliais do oviduto bovino em suspensão sob óleo de silicone. As condições de cultivo in vitro para ambos os experimentos seguiram os tratamentos: 1- meio B-199 + 200 ng/ml IGF-I; 2- B-199 + 100 ng/ml IGF-I; 3- B-199 + 50 ng/ml IGF-I; 4- B-199 + 10 ng/ml IGF-I; 5- B-199 + 0 ng/ml IGF-I. Todas as culturas foram realizadas a 38,5° C em atmosfera com 5% de CO2 e os dados foram analisados pelo teste do qui-quadrado. No experimento I, não houve diferença (P>0,05) entre os tratamentos quanto às TC, TB e TE, quando o meio de MIV foi suplementado com IGF-I. No experimento II, a adição de IGF-I ao meio de DE resultou em aumento na TC (P<0,05) mas não influenciou a TB e a TE. A adição de 200 ng/ml de IGF-I ao meio DE melhorou a TC (71,1%) quando comparada com a TC dos grupos de 100 ng/ml de IGF-I (57,6%) ou controle (56,7%), entretanto não houve diferença quando comparada com a dos grupos de 50 ng/ml (69,4%) ou 10 ng/ml (73,1%) de IGF-I. Não houve efeito benéfico na adição de 10 a 200 ng/ml de IGF-I nos meios de MIV e de DE com relação ao desenvolvimento de embriões produzidos a partir de oócitos maturados e fecundados in vitro.

Fecundação in vitro de ovócitos bovinos com sêmen submetido a diferentes diluidores

O objetivo deste trabalho foi avaliar a influência do diluidor do sêmen no desenvolvimento in vitro de ovócitos bovinos após a maturação e fecundação in vitro. Ejaculado de um reprodutor foi fracionado e submetido a três diluidores: Lactose/gema de ovo (LG), Citrato/gema de ovo (CG) e Tris/gema de ovo (TG). Amostras deste material foram envasadas, congeladas e estocadas em N² e, posteriormente, descongeladas; a fração móvel foi separada por gradiente descontínuo de Percoll. A concentração espermática foi ajustada para 10 x 10(6)/mL e a capacitação espermática, induzida com 10 µg/mL de heparina. Após 24 horas de cultura para maturação in vitro, os ovócitos, aspirados de folículos ovarianos, foram inseminados com sêmen diluído em meio TALP e, após 48 horas de cultura, os zigotos foram transferidos para gotas de meio TCM 199, com 5% de soro fetal bovino, 5% de soro de vaca em estro e suspensão de células epiteliais do oviduto bovino, cobertas com óleo de silicone, e mantidos em cultura por nove dias. Todas as culturas foram realizadas a 38,5ºC em atmosfera com 5% de CO2. Os dados foram analisados pelo teste do qui-quadrado e houve diferença com relação à taxa de clivagem (TC), sendo as médias de 66,0; 69,3; e 54,4% para LG, CG e TG, respectivamente. Não houve diferença entre tratamentos com relação às taxas de mórulas/blastocistos ou de eclosão. O diluidor do sêmen não teve efeito sobre o desenvolvimento in vitro de embriões bovinos, embora a TC tenha sido afetada.

Professores de ciências naturais: necessidades formativas para ensinar a medir em trabalhos práticos e experimentais

This paper presents a research realized with Physics, Chemistry and Biology teachers, and it aimed to evaluate: 1) the development level of those teachers regarding the abilities that make possible to teach high school students about how to measure in practical and experimental work; 2) the formatives necessities regarding those abilities; and 3) the order of priority for teacher´s formation regarding those abilities. The study is based on the activity theory, from A. N. Leontiev (1983), since we considerer the teacher´s formation a kind of activity for which the category necessity is source of motivation and in which is a necessary condition for professionality and for the professional development. A questionnaire with open and closed questions was applied to 116 teachers during three pedagogic workshops realized to dynamize the science laboratory. The instrument allowed us to obtain the personal and professional profile of the participants, as well as their development level, their formative necessities and their order of priority about the teaching of the abilities related to the work of testing measuring hypothesis, regarding: a) to operationalize variables of a hypothesis in experimental work; b) to measure in practical and experimental work; c) to estimate possible measuring mistakes and use proper procedures to minimize them; d) to estimate the validity of a measuring; and e) to estimate the confiability of a measuring. The research results indicated some limitations of the teachers about their development level in all the analyzed abilities. More than 90% of the teachers considered those deficiencies as necessities of the continuing formation. Most of them (about 54%) expressed immediate priority for formation in each one of the abilities. From a correlation, using the statistic chi-square test, between the development level and the formative necessities for the five abilities, the obtained results allow us to assure that, for all those teaching abilities, there is a strong correlation between the development level and the formative necessity. This situation is symptomatic of the importance of approaching more the science teaching and the teacher´s formation on practical and experimental work in high school as key-component of scientific education in basic education. The obtained results can contribute, as subsidy, for continuing formation courses, having as base the necessities that constitute motivation elements of the teachers for professional development

A quantitative nature of somatic embryogenesis in soybean

The objectives of this research were to investigate the genetic parameters associated with the in vitro formation of somatic embryos in soybean and to determine the effect of light intensity on the embryogenic capability of F-1, F-2, and backcross (RC1P1 and RC1P2) progenies derived from crosses between embryogenic (IAS-5 and Embrapa-1) and nonembryogenic (Parana) cultivars. Immature cotyledons (4-6 mm in length) derived from the parental lines, F-1, F-2, RC1P1, and RC1P2 were grown for 90 d on the inductive N10 medium, after which the number of somatic embryos was recorded. Chi-square tests for goodness of fit showed that the genetic component of the somatic embryogenesis trait is controlled in a quantitative manner by approximately 10 genes. A normal distribution for somatic embryo formation in the F-2 generations was observed reinforcing the quantitative nature of the trait. Variation in light intensity (8-12 and 27-33 mu mol m(-2) s(-1)) had no effect on somatic embryo formation in the parental material tested.

Conhecimento dos enfermeiros do Hospital Universitário Onofre Lopes sobre sistematização da assistência de Enfermagem

Nursing as a profession goes in search on quality of their care through new frameworks, trying to break postures of the health care system so fragmented in the care. To change professional practices, it is necessary to build their own knowledge grounded on Nursing Care System. The aim of this study was to analyze the influence of nurses' knowledge on care systematization in nursing in the University Hospital Natal-RN. It is an analytical descriptive study carried out at the Onofre Lopes University Hospital (HUOL), Natal-RN, 2010, the sample was composed of 40 active nurses working in hospitalization units of the hospital, the inclusion criteria were being in the monthly scale sector and agree to participate in the study. The non-participant observation and another interview were used for collecting data, statistical analysis was descriptive and inferential with reliability test, Pearson test, chi-square and Fischer, the variables that correlated were analyzed in a model Multiple logistic , calculating odds ratio. The results were: predominance of female professionals (90%), predominantly in the age range 39-46 years (37.5%), nurses who have the undergraduate degree at the Federal University of Rio Grande do Norte (80%), and who have expertise training as a minimal degree (62.5%). Among the surveyed, the knowledge showed significance with the graduation time (p = 0.018) and time working in HUOL (p = 0.036). The majority of the professionals surveyed do not know which organ is responsible for the SAE legislation (52.5%), aware of the steps needed to build the nursing diagnosis (92.5%), understand the characteristics of nursing planning (90% ). However the same professionals do not perform physical examination in patients (50.0%) did not classify the clinical findings (68.4%), and identify the problems encountered as a classification (13.2%). The planning of nursing care is carried out by verbal order of nurses (82.5%), 41% of the professionals assess only the intervention stage, in other words, the actions taken. Regarding the practical application of nursing records 53% of nurses do not realize records, 30.8% is incomplete, the other held notes (p = 0.003). The nurses know the nursing process (90% of appropriate responses), despite the actions defined by the theory are not applied in practice. Investigators believe the condition of the hospital teacher (22.5%) could positively affect the implementation of the SAE associated with the interest of professionals (20%). Of the respondents, 17.5% accept as truth the lack of facilities to assist the SAE implementation in the hospital. It was concluded that nurses know the theory that underlies the SAE and the nursing process, but do not develop the service know as well, there is need for action to boost the SAE implementation as practice of nurses in the hospital investigated

Validation of microsatellite markers for assisted selection of soybean genotypes resistant to powdery mildew

Powdery mildew is one of the most serious diseases of soybean and is found in all producing countries. The purpose of this study was to validate microsatellite markers previously identified as associated with resistance to powdery mildew in soybean. The study was conducted in two F, parent populations with contrasting resistance to powdery mildew, In the analysis 10 SSR primers were used for the populations. and tour polymorphic markers were identified for cross I (MGBR95-20937 x IAC-Foscarin 31) and three for cross 2 (MGBR-46 x Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) 48). The Chi-square analysis of the phenotypic evaluation confirmed the expected segregation (3: 1) of a dominant gene related to resistance. The polymorphic markers also segregated as expected (1:2:1). The markers Sat 366 and Sat 393 in the crosses 1 and 2. respectively, located at 9.41 and 12.45 cM from the gene. were considered promising for marker-assisted selection for resistance to powdery mildew in soybean. at a selection efficiency of 92.7% and 60.3% respectively.

Marcadores RAPD para detecção de resistência à ferrugem-asiática-da-soja

Os objetivos deste trabalho foram confirmar a herança da resistência da PI 459025 (Rpp4) à ferrugem-asiática-da-soja e identificar marcadores moleculares do tipo RAPD, ligados a este gene de resistência, em populações de soja. Pelo cruzamento dos genitores contrastantes PI 459025 x Coodetec 208 obteve-se uma população, cujas populações das gerações F2 e F2:3 foram artificialmente infectadas e avaliadas quanto à reação ao fungo Phakopsora pachyrhizi, pelo tipo de lesão (RB - resistente e TAN - suscetível). Com os resultados da avaliação fenotípica, dois bulks foram obtidos com DNA de plantas homozigóticas resistentes e suscetíveis, respectivamente, pela análise de bulks segregantes. de 600 iniciadores RAPD aleatórios, foram identificados três com fragmentos polimórficos entre os bulks e parentais contrastantes quanto à resistência. Pela análise do qui-quadrado, confirmaram-se: a herança monogênica, com dominância completa quanto à resistência ao patógeno, e a segregação 3:1 para a presença de banda dos três marcadores. Os três marcadores são ligados respectivamente a 5,1, 6,3 e 14,7 cM de distância do loco de resistência, em fase de repulsão no grupo de ligação G, o que foi confirmado pela utilização do marcador microssatélite Satt288. Estes marcadores são promissores na seleção assistida para resistência à ferrugem-asiática-da-soja.

Atuação do enfermeiro na rede básica de saúde frente a gestante com infecção do trato urinário

The Urinary Tract Infection (UTI) in pregnancy is important as a consequence of the high incidence during the gestation. It is the third most common clinical complication in pregnancy affecting 10-12% of women whether prevalence is increasing in the first trimester of pregnancy, it may also contribute to maternal and infant mortality. Due the relevance for the results of obstetric and neonatal complications from UTI, these complications must be prevented, because it can lead to health hazards to pregnant women and newborns, producing a direct effect on morbidity and perinatal mortality. On this basis, it was defined as objectives of this research the identification of the profile of nurses from the Family Health Strategy (FHS) in the East and West Health Districts from the city of Natal / RN before the women with UTI and to verify the nurse performance during prenatal consultations. This is an exploratory study with a quantitative approach using a sample of 40 nurses active workers during this survey, it was approved by the Research Ethics Committee of the Universidade Federal do Rio Grande do Norte Protocol n0 232/10 P-CEP/UFRN and opinion n0 080/2011. The tool for data collection was a structured interview. The data collected were organized into an electronic database application Microsoft ® Excel 2007, exported and analyzed using the Statistical Package for Social Sciences (SPSS) version 17.0, and coded, tabulated and presented through tables and charts into their respective percentage distributions, using the descriptive and inferential statistical analysis, chi-square test and significance level of 5% (distribution in relative and absolute frequencies) in the independent variables. Therefore, it was observed from these results that the longer action of nurses in the FHS from the East and Weast health districts of the city of Natal/RN contributed to the development of a greater number of activities to control the incidence of UTI in women who are attended in the prenatal care service, proven by significance in statistics

Validação de conteúdo do instrumento para consulta de enfermagem na visita domiciliar às pessoas com lesão medular: um enfoque no autocuidado

This study aimed to validate the contents of an Instrument for Nursing Consultation in the Home Visit of people with Spinal Cord Injury (INCEVDOP-LM), based on the Self-Care Deficit Theory. The methodological development study was conducted with spinal cord injured (SCI) people ascribed in the Family Health Units the city of Natal/RN/Brazil, and with the nurses of these institutions. The study was conducted from Januray 2012 to January 2013 in two phases: the first aimed to identify the need for self-care of persons with SCI, and the second to develop and validate the INCEVDOP-LM. The first phase consisted of a census study of people with SCI living in Natal/RN. In the second phase, a non-probabilistic convencience sample of subjects was selected to form two groups: First stage - Group 1 of the first stage was comprised by 73 adults with SCI diagnosed with paraplegia or tetraplegia, with cognitive function preserved and that were registered to some family health unit; Group 2 of the Second phase was composed of six experts that were nurses with doctoral formation, scientific experience in the area of technology development or assistance to persons with SCI, and with publications in periodicals Qualis A2. Data collection of the first phase was conducted through home visits of people with SCI that responded three instruments: Questionnaire I (comprised of demographic and socioeconomic variables), The Competency Rating Scale for Self-care (ASA) and the Barthel Index (an instrument for evaluation of functional capacity). The research for the second phase was conducted in two stages: I-construction of the INCEVDOP LM; II-validation of the INCEVDOP-LM. The instrument and an evaluation form were forwarded to the experts for the validation. The correlations between the responses were analyzed by the Kappa test, with accepting values of>0.75. The evaluation criteria were: organization, clarity, simplicity, readability, appropriateness of vocabulary, objectivity, accuracy, reliability and suitability and the positive responses with frequency values of≥90% were considered excellent. The chi-square test was used to investigate the differences between proportions. The study attended to the principles of Human Rights CNS Resolution 196/96. Results were reported by means of four articles derived from the study. The findings indicate that the items that showed disagreement among experts (k=0.02) were diagnoses, interventions and evaluation of the nursing features pertaining to the domains of Nutrition, Hygiene, Elimination, Physical, Social and Psychological, and of the Ability to perform work activities feature. Agreement among the experts were reported for the other items, with kappa ranging from 0.72 to 1. After removing items with disagreement, all criteria achieved excellent rates and no significant differences were observed between the proportions of responses of evaluation of experts (p>0.05). We conclude that the instrument shows validity to serve as a guide for nurses to conduct a systematic consultation during the home visit to people with spinal cord injury, with emphasis on self-care. The instrument must go through other levels of validation when applied in the clinical setting

Fatores associados à efetividade da doação de órgãos e tecidos para transplantes

The transplantation of organs and tissues presents itself as an important therapeutic option, both from a medical standpoint, the social or economic. Thus, the identification of variables that can interfere in the effectiveness of organs and tissues donation for transplantation needs to be investigated adequately, because it stands before increasing index of chronic and degenerative diseases in the population, what makes the waiting list for transplantation grow disproportionately and patients come to death without the opportunity of realization the treatment due to a lack of donors. In this context, has defined as objective of this study evaluate the factors associated with the effectiveness of organs and tissues donation for transplantation. It is a evaluative research, quantitative, prospective, with longitudinal design, developed at Central of Catchment, Notification and organ donation for transplant, Organ Procurement Organization and in six accredited hospitals to collect and transplantation of organs and tissues, in Natal/RN, between august 2010 and february 2011, after the approval of the Research Ethics Committee, under No. 414/10 and CAAE 007.0.294.000-10. The probabilistic sample without replacement was composed of 65 potential donors. It was used as an instrument of data collection a structured script non-participant observation of checklist type. Data were analyzed using descriptive statistics and presented in tables, charts, graphs and figures. For this, was used Microsoft Excel 2007 and statistical program SPSS version 20.0. To check the level of significance was chosen by applying the chi-square test (χ2) and Mann Whitney and caselas for less than five, it is considered the Fisher exact test. It was adopted as the significance level p-value <0.05. Among the surveyed it was observed that most of the individuals were male (50,8%), in the age group 45 years (53,8%), mean age of 42,3 years, minimum 5 and maximum 73 years (± 17,32 years). Single / widowers / divorced (56,9%), with up to completed elementary school (60,0%) in the exercise of professional activity (86,2%), catholic (83,1%) and residents in metropolitan region of Natal (52,3%). Was obtained donation effectiveness of 27,7%. There was no statistical significance between structure and effectiveness of the donation, but were observed inadequacies in physical resources (36,9%), materials (30,8%), organizational structure (29,2%) and human resources (18,5%). In the process, the maintenance phase (p= 0.004), diagnosis of brain death (p= 0.032), family interview (p≤ 0.001) and documentation (p= 0.001) presented statistical significance with effectiveness. Thus, it is accepts the alternative hypothesis of the study, in which is evidenced that the adequacy of the factors related to structure and process is associated to effectiveness of organs and tissues donation for transplantation. In this way, the effectiveness of organ and tissue donation ends in an essential way the rapidity and accuracy with which the donation process is conducted, requiring appropriate structure, with appropriate physical and material resources and skilled human resources to optimize the reduction of time and the suffering of those waiting for an organ or tissue transplant queued in Brazil
