ABSTRACT Purpose Bladder endometriosis (BE) accounts for 84% of cases of urinary tract involvement. The use of cystoscopy for preoperative evaluation is limited. The aim of this study was to evaluate the accuracy of preoperative dynamic cystoscopy (DC) in patients undergoing surgery for deep endometriosis and to describe the main findings and their impact on surgical planning. Materials and Methods This cross-sectional observational study was conducted from January 2011 to March 2022. DC findings were divided into two groups according to the depth of involvement. To estimate sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), laparoscopic findings of bladder involvement and histopathological report were used as the gold standard. Results We included 157 patients in this study. 41 had abnormalities in DC. Of these, 39 had abnormalities that were confirmed intraoperatively. The sensitivity and specificity of the test were 58.21% and 97.78%, respectively. PPV was 95.12%, and NPV was 75.86%. The presence of any lesions in the DC had a diagnostic odds ratio (OR) of 61.28 for BE. Patients with BE type 2 had a higher rate of partial cystectomy than those with BE type 1 lesions (OR 9.72 CI 95% 1.9-49.1) Conclusion DC appears to be a highly specific test with lower sensitivity. DC abnormalities are associated with a higher ratio of bladder surgery for the treatment of deep endometriosis, and BE type 2 seems to be associated with a greater ratio (9.72) of partial cystectomy.

Abstract Objectives: The purpose of this study is to evaluate, over a simulated 5-year period, the effect of simulated gastric juice alternated with brushing on CAD-CAM monolithic materials considering microhardness, substance loss, flexural strength, and reliability of the materials. Methodology: Blocks from Lava Ultimate (LU), Vita Enamic (VE), IPS Empress CAD (EMP), IPS e.max CAD (EMAX), and Vita Suprinity (VS) were milled into cylinders and sliced into disks. The EMAX and VS were crystallized, and all specimens were polished with silicon carbide papers and allocated as follows: 1) artificial saliva + brushing or 2) simulated gastric juice (0.113% hydrochloric acid (HCl) solution in deionized water, pH 1.2) + brushing, simulating 1, 3, and 5 years of clinical function. Each year of clinical function was simulated by three repetitions of immersion for 3 hours in artificial saliva or simulated gastric juice followed by 1,217 brushing cycles. The microhardness and substance loss were evaluated at baseline (T0) and at each year by using a Vickers hardness tester and an analytical balance. The biaxial flexural strength (BFS) test was performed in a mechanical testing machine at the end of the 5th year. Weibull modulus was calculated from the BFS data. Results: The microhardness of the LU was not influenced by the treatment, whereas that of the other materials, in certain years, was significantly lower in the gastric juice + brushing groups in comparison with artificial saliva + brushing groups. In general, the materials did not present a significant change in microhardness over time, for either of the treatments. The LU alone showed greater substance loss in the gastric juice + brushing groups for every year. In both treatments, the LU, VE, and EMP exhibited a significant increase in the substance loss over time. The treatment did not affect the BFS of the materials. The gastric juice + brushing decreased the reliability of the VE. Conclusions: All materials were somehow impaired by the gastric juice + brushing in at least one of the evaluated parameters, except for the BFS. However, in a deeper analysis, the LU would be the least indicated materials, followed by VE, for patients with eating disorders.

Resumo Objetivo: Descrever e analisar o prognóstico de crianças ao longo do primeiro ano de vida com diagnóstico de hérnia diafragmática congênita admitidas entre 2005 e 2015 na Unidade de Terapia Intensiva Neonatal. Método: Em uma coorte retrospectiva estudamos 129 crianças com diagnóstico de hérnia diafragmática congênita. Foram analisados os fatores prognósticos onde as variáveis de exposição do pré-natal, parto e pós-natais foram associadas ao óbito no primeiro ano de vida. Calculamos a odds ratio (OR) e o intervalo de confiança (IC95%) para todas as variáveis estudadas, sendo utilizados os testes de qui-quadrado e o teste T Student. Resultados: Foram incluídos no estudo 129 crianças, internados de janeiro/2005 a dezembro/2015. Foram a óbito 79 (61%) pacientes, 50 sobreviveram e 33 tinham outras malformações associadas. Entre os fatores prognósticos foram significativos e aumentaram a chance de óbito a polidrâmnia (p = 0,001), idade gestacional do diagnóstico mais precoce (p = 0,004), anomalias congênitas associadas (OR: 3,013, p = 0,022), pO2 da primeira gasometria (p = 0,000), pCO2 da primeira gasometria (p = 0,000), presença de hipoplasia pulmonar (OR: 3,074, p = 0,000), uso de drogas vasoativas pré-operatórias (OR: 2,881, p = 0,000) e o uso de oxido nítrico (OR:1,739, p = 0,000). A presença de apenas intestinos no conteúdo da hérnia foi um fator protetor (OR: 0,615, p = 0,001). Conclusão: A mortalidade no primeiro ano de vida em portadores de hérnia diafragmática congênita, neste estudo, foi de 61% de 2005 a 2015. Entre os fatores prognósticos que demonstraram um efeito significativo, a hipoplasia pulmonar foi o de maior impacto.

Abstract Objective: To describe and analyze the prognosis of children during the first year of life with a diagnosis of congenital diaphragmatic hernia admitted between the years 2005 and 2015 in the Neonatal Intensive Care Unit. Method: In a retrospective cohort, 129 children with a diagnosis of congenital diaphragmatic hernia were studied. The prognostic factors were analyzed, whereupon prenatal, delivery, and postnatal exposure variables were associated with death during the first year of life. The odds ratio and the confidence interval (95% CI) were calculated for all the studied variables, using the chi-squared test and Student's t-test. Results: The study included 129 children hospitalized from January of 2005 to December of 2015. Seventy-nine (61%) patients died, 50 survived, and 33 had other associated malformations. Among the prognostic factors, the following were significant and increased the chance of death: polyhydramnios (p = 0.001), gestational age of the earliest diagnosis (p = 0.004), associated congenital abnormalities (OR: 3.013, p = 0.022), pO2 of the first gasometry (p = 0.000), pCO2 of the first gasometry (p = 0.000), presence of pulmonary hypoplasia (OR: 3.074, p = 0.000), use of preoperative vasoactive drugs (OR: 2.881, p = 0.000), and use of nitric oxide (OR: 1.739, p = 0.000). The presence of only intestines in the hernia content was a protective factor (OR: 0.615, p = 0.001). Conclusion: The mortality in the first year of life in patients with congenital diaphragmatic hernia in this study was 61% in the years 2005-2015. Among the prognostic factors that demonstrated a significant effect, pulmonary hypoplasia had the greatest impact.

ABSTRACT The present study had as the main objective the documentation and characterization of the different phenological stages, as well as the definition of the thermal requirements, of the atemoya tree for two agronomic seasons. From shoot development to senescence and beginning of the rest period eight main stages were described (shoot development, leaf development, shoot/bud growth, inflorescence appearance, flowering, fruit development, fruit maturity and senescence and the beginning of the rest period). The number of days and the thermal requirements for completing each phenological stage were different between the two agronomic seasons of the atemoya. The first and second agronomic season presented a period of 217 and 206 days, with thermal requirements of 2469 and 2302 degree days, respectively.

ABSTRACT Maize is one of the species with greater genetic diversity among cereals and possibly the most diverse crop species known. Accessing this variability is essential for maize breeding, allowing breeders to achieve progress of yield increasing, overcome environmental challenges or deal with pests and diseases. Among the maize diseases, southern rust is one of the most important, causing significant losses in yield and presenting severe epidemics worldwide. In the present study, the AFLP technique was applied to analyze population structure and genetic diversity among 145 tropical maize inbred lines, and to test for preliminary evidence of association between AFLP markers and the reaction to southern rust. Disease severity was evaluated in two crop seasons and the accessions were genotyped through AFLP using four primer combinations. The clusters obtained based on the Jaccard genetic distance and Ward’s hierarchical clustering and those achieved by structure simulations had high concordance and were capable of establish two big clusters, one predominantly of common maize and another of popcorn. The association analysis was performed using four different statistical models. The more complete model containing both population structure and genetic relatedness narrowed the number of significant associations, demonstrating its importance to control false associations. A total of 19 significant marker associations were identified from which three (EactMctg18, EactMctg205, EactMctg169) are interesting candidates for further investigations.

RESUMO: O objetivo desse estudo foi investigar a influência da adição dos prebióticos farelo de arroz, inulina e hi-maize, na sobrevivência de Lactobacillus acidophilus em micropartículas de alginato obtidas por gelificação externa seguida de liofilização. Analisou-se o tamanho das micropartículas, a viabilidade, em simulação gastrointestinal e estabilidade, durante armazenamento. O tamanho das micropartículas variou de 127.5µm a 234.6µm. As micropartículas adicionadas dos diferentes prebióticos demonstraram um aumento na proteção do microrganismo, que apresentou maior viabilidade frente à simulação gastrointestinal. Quanto ao armazenamento em diferentes condições, a 25ºC o tratamento farelo de arroz manteve os probióticos viáveis por 30 dias. Nas condições de armazenamento -18ºC e 7°C os tratamentos contendo os prebióticoshi-maize e farelo de arroz mantiveram os microrganismos probióticos viáveis por um período de 60 dias.

ABSTRACT: The aim of this study was to investigate the influence of the addition of prebiotics rice bran, inulin and hi-maize, on the survival of Lactobacillus acidophilus in alginate microparticles obtained by external ionic gelation followed by freeze-drying. The microparticles size ranged from 127.5μm to 234.6μm. Microparticles added from the different prebiotics demonstrated an increase in the protection of the microorganism, which presented greater viability against the gastrointestinal simulation. As for storage under different conditions, rice bran treatment at 25ºC kept probiotics viable for 30 days. Under storage conditions -18°C and 7°C, treatments containing prebiotics hi-maize and rice bran maintained viable probiotic microorganisms for a period of 60 days.

Resumo O objetivo do estudo foi avaliar a cultura de segurança do paciente e fatores associados em hospitais brasileiros com diferentes tipos de gestão: federal, estadual e privado. O desenho foi observacional transversal. Enviaram-se 1576 questionários aos profissionais de três hospitais do estado do Rio Grande do Norte, utilizando o Hospital Survey on Patient Safety Culture, adaptado para o Brasil, que mede 12 dimensões da cultura de segurança. As percepções são descritas através de uma nota geral (0 a 10) e dos percentuais de respostas positivas para estimar fortalezas e fragilidades em cada dimensão. A taxa de resposta foi de13,6% (n = 215). A segurança do paciente teve nota entre 7 e 10, para 78,1% dos respondentes, sendo a maior média das notas apresentada pelo hospital privado (8,32). O tipo de gestão hospitalar, unidade de serviço, cargo e quantidade de notificação de eventos adversos estiveram associados à nota geral da segurança do paciente (p < 0,001). Apenas o hospital privado apresentou fortalezas nas dimensões analisadas, enquanto que as fragilidades apareceram em todos os hospitais.

Abstract The scope of the study was to evaluate patient safety culture and associated factors in Brazilian hospitals with different types of management, namely federal, state and private hospitals. The design was cross-sectional and observational. A survey of 1576 professionals at three hospitals of Rio Grande do Norte state was performed using the Hospital Survey on Patient Safety Culture adapted for Brazil, which measures 12 dimensions of safety culture. Perceptions are described by attributing a general result (Range 0-10) and the percentage of positive responses to estimate their strengths and weaknesses. The response rate was 13.6% (n= 215). The patient safety coefficient was between 7 and 10 for 78.1% of the respondents, whereby the highest average grade was attributed to the private hospital (8.32). It has been estimated that the type of hospital management, unit service, position and number of adverse event notifications are associated with the overall patient safety grade (p <0.001). Only the private hospital had strengths in the dimensions analyzed, while the weaknesses appeared in all the hospitals.

OBJETIVO: Testar preditores do ritmo de intravasamento durante histeroscopia cirúrgica.MÉTODOS: Estudo prospectivo observacional (classificação: Canadian Task Force II-1) incluindo casos conduzidos em centro cirúrgico (n=200 mulheres; 22 a 86 anos de idade). Considerando os erros de aferição nas embalagens de solução de irrigação para calcular o balanço hídrico, nós testamos dois modelos de regressão linear múltipla: um para intravasamento total (mL) e outro para ritmo de intravasamento (mL.min-1). Os preditores testados (variáveis independentes) foram energia (mono/bipolar), permeabilidade tubária (com/sem ligadura tubária), histerometria (cm), status ovariano (idade≤50 anos), área de superfície corporal (m2), complexidade de cirurgia (com/sem miomectomia) e tempo de ressecção (min).RESULTADOS: O intravasamento médio foi significativamente maior quando miomectomia foi realizada (442±616 versus 223±332 mL, p<0,01). No modelo proposto para intravasamento total (R2 ajustado=0,44; p<0,01), os únicos preditores significativos foram miomectomia e tempo de duração (p<0,01). No modelo proposto para a taxa de intravasamento (R2=0,39; p<0,01), somente miomectomia e histerometria foram preditores significativos (p=0,02 e p<0,01, respectivamente).CONCLUSÕES: Não só a miomectomia mas também a histerometria são preditores significativo da taxa de intravasamento durante histeroscopia cirúrgica.

PURPOSE: To verify the predictors of intravasation rate during hysteroscopy.METHODS: Prospective observational study (Canadian Task Force classification II-1). All cases (n=200 women; 22 to 86 years old) were treated in an operating room setting. Considering respective bag overfill to calculate water balance, we tested two multiple linear regression models: one for total intravasation (mL) and the other for absorption rate (mL.min-1). The predictors tested (independent variables) were energy (mono/bipolar), tube patency (with/without tubal ligation), hysterometry (cm), age≤50 years, body surface area (m2), surgical complexity (with/without myomectomy) and duration (min).RESULTS: Mean intravasation was significantly higher when myomectomy was performed (442±616 versus 223±332 mL; p<0.01). In the proposed multiple linear regression models for total intravasation (adjusted R2=0.44; p<0.01), the only significant predictors were myomectomy and duration (p<0.01).In the proposed model for intravasation rate (R2=0.39; p<0.01), only myomectomy and hysterometry were significant predictors (p=0.02 and p<0.01, respectively).CONCLUSIONS: Not only myomectomy but also hysterometry were significant predictors of intravasation rate during operative hysteroscopy.

ABSTRACT: In this work, we present the results of verification of special neutron monitoring equipment for use in aircrew dosimetry inside aircraft. The equipment was precalibrated with conventional neutron sources in a National Standard Laboratory of the Institute for Radioprotection and Dosimetry (IRD, Brazil) and verified in a Cosmic Energy Reference Field (CERF), a special field from CERN (Centre Européan de Recherche Nucléaire), a facility that reproduces the shape of neutron field encountered in the atmosphere at aircraft altitudes. The equipment consists of a special neutron probe from Thermo Scientific with response up to 5 GeV neutrons and was verified with respect to ambient dose equivalent rate linearity and angular incidence. The results show the adequacy of the equipment for this type of measurement and the feasibility to use conventional neutron sources to calibrate this specific equipment, in the absence of access to the CERF field.

Objetivou-se com este estudo avaliar o desempenho e a qualidade dos ovos de codornas japonesas (Coturnix japonica) alimentadas com rações cotendo sorgo de baixo tanino em substituição ao milho. Foram utilizadas 210 codornas japonesas fêmeas com 65 dias de idade, distribuídas em delineamento inteiramente casualizado com cinco rações experimentais (0; 25; 50; 75 e 100% de sorgo em substituição ao milho) e seis repetições de sete aves. No experimento, cuja duração foi de 112 dias, não houve efeito significativo dos níveis de sorgo nas rações sobre nenhuma das características de produção. Com aumento dos níveis de sorgo na ração, houve redução linear da cor da gema e do custo da ração. O sorgo de baixo tanino pode substituir totalmente o milho em rações para codornas japonesas em postura.

The aim of this study was to evaluate performance and egg quality of Japanese quails (Coturnix japonica) fed rations with low-tannin sorghum replacing corn. Two hundred and ten 65-d female Japanese quails were distributed in a complete random design with five experimental rations (0, 25, 50, 75 and 100% replacement of corn by sorghum) and six replicates with seven birds. There was no significant effect of sorghum levels in the diets on any of the production characteristics in this experiment, which lasted for 112 days. As the levels of sorghum in the ration increased, yolk color and ration cost were reduced. Low-tannin sorghum can completely replace corn in rations for laying Japanese quails.

A substituição do milho pelo sorgo promove redução na pigmentação da gema dos ovos, sendo necessária a inclusão de fontes exógenas de pigmentantes. Objetivou-se com este estudo avaliar às características sensoriais dos ovos de codornas japonesas (Coturnix japonica (Temminck & Schlegel, 1849) alimentadas com rações formuladas com sorgo, em substituição total ao milho, com a inclusão de pigmentantes sintéticos amarelo (apocaroteno 10%) e vermelho (cantaxantina 10%) e selenometionina. Foram utilizados os seguintes tratamentos: T1: ração referência; T2: ração com sorgo (RS); T3: RS+apo-éster; T4: RS+apo-éster+cantaxantina e T5: RS+apo-éster+cantaxantina+selenometionina. Utilizaram-se 30 provadores não-treinados para avaliação quanto ao sabor do ovo e cor da gema, analisados pelo Teste de Comparação Pareada -Grau de diferença com 0,05 de probabilidade. Os dados ao serem analisados, utilizando a Tabela de Número Mínimo de Respostas Coincidentes, ao nível de 5% de significância, indicaram que os provadores detectaram diferença na intensidade de sabor e cor entre a amostra padrão e os tratamentos. O grau de diferença para o atributo sabor foi de intensidade leve entre a amostra padrão e os tratamentos T2, T4 e T5. Para o atributo cor, o grau de diferença foi considerado de intensidade leve a grande entre a amostra padrão e a dos tratamentos. Pode-se utilizar os pigmentantes sintéticos apoéster e cantaxantina associados com selenometionina em rações a base de sorgo para codornas japonesas.

Synthetic pigments from external sources are supplemented in sorghum replacement diets in the substitution for the corn diet of Japanese quails, in order to compensate the decrease in egg yolk color. The purpose of this research was to evaluate the effect of the following synthetic pigments: yellow (apo-ester), red (canthaxanthin), and selenomethionine on sensorial characteristics of eggs laid by Japanese quails fed ration formulated with sorghum, totally substituting a corn diet. The following treatments were used: T1-control diet; T2-sorghum diet (SD); T3-SD + apo-ester; T4-SD + apo-ester + canthaxanthin; T5-SD + apo-ester + canthaxanthin + selenomethionine. Thirty non-trained individuals evaluated egg flavor and yolk color. Average differences were accessed by a paired comparison test at the 5% significance level. Significant differences between the standard sample and treatment samples were observed for flavor and color characteristics of the egg, using a minimum number of coincident answers at the 5% significance level. The degree of flavor difference ranged from low intensity between the standard sample and treatment samples T2, T4, and T5. The degree of color difference ranged from moderate to high intensity between the standard sample and treatment samples. Synthetic pigments (apo-ester and canthaxanthin) associated with selenomethionine in sorghum based diets can be used for Japanese quails.
