ABSTRACT Objective To describe the most common sexual problems and changes experienced by male urological cancer survivors, focusing on evidence-based practices for assessment and intervention. Materials and Methods We search the PubMed, Embase, and SciELO databases between 1994 and 2022, using the following key words: “urological cancer”, “urological malignances”, “genitourinary cancer”, “male sexual health”, and “male sexual dysfunction”. Results This narrative review provides an overview of the current literature involving the impact of diagnosis and treatment of urological cancers on male sexual function. Male “genital” or “reproductive” tumors, such as prostate, penile, and testicular tumors, clearly appear to affect sexual function. However, tumors that do not involve genital parts of the body, such as the bladder and kidney, can also affect male sexual function. Conclusion Male sexual dysfunction is very common after urologic cancer diagnosis and treatment. Changes in body image and anatomical damage can be associated with impaired masculinity and sexual function, especially after prostate, penile or testicular cancer treatment. Moreover, anxiety, depression, and fear of recurrence have an impact on quality of life and sexual function regardless of the cancer location. Therefore, patients need be counseled about the likely changes in sexual function before treatment of any urological cancer.

Abstract Objective: To determinate the accuracy of computed tomography (CT) imaging assessed by deep neural networks for predicting the need for mechanical ventilation (MV) in patients hospitalized with severe acute respiratory syndrome due to coronavirus disease 2019 (COVID-19). Materials and Methods: This was a retrospective cohort study carried out at two hospitals in Brazil. We included CT scans from patients who were hospitalized due to severe acute respiratory syndrome and had COVID-19 confirmed by reverse transcriptionpolymerase chain reaction (RT-PCR). The training set consisted of chest CT examinations from 823 patients with COVID-19, of whom 93 required MV during hospitalization. We developed an artificial intelligence (AI) model based on convolutional neural networks. The performance of the AI model was evaluated by calculating its accuracy, sensitivity, specificity, and area under the receiver operating characteristic (ROC) curve. Results: For predicting the need for MV, the AI model had a sensitivity of 0.417 and a specificity of 0.860. The corresponding area under the ROC curve for the test set was 0.68. Conclusion: The high specificity of our AI model makes it able to reliably predict which patients will and will not need invasive ventilation. That makes this approach ideal for identifying high-risk patients and predicting the minimum number of ventilators and critical care beds that will be required.

Resumo Objetivo: Determinar a acurácia da tomografia computadorizada (TC), avaliada por redes neurais profundas, na ventilação mecânica, de pacientes hospitalizados por síndrome respiratória aguda grave por COVID-19. Materiais e Métodos: Trata-se de estudo de coorte retrospectivo, realizado em dois hospitais brasileiros. Foram incluídas TCs de pacientes hospitalizados por síndrome respiratória aguda grave e COVID-19 confirmada por RT-PCR. O treinamento consistiu em TC de tórax de 823 pacientes com COVID-19, dos quais 93 foram submetidos a ventilação mecânica na hospitalização. Nós desenvolvemos um modelo de inteligência artificial baseado em redes de convoluções neurais. A avaliação do desempenho do uso da inteligência artificial foi baseada no cálculo de acurácia, sensibilidade, especificidade e área sob a curva ROC. Resultados: A sensibilidade do modelo foi de 0,417 e a especificidade foi de 0,860. A área sob a curva ROC para o conjunto de teste foi de 0,68. Conclusão: Criamos um modelo de aprendizado de máquina com elevada especificidade, capaz de prever de forma confiável pacientes que não precisarão de ventilação mecânica. Isso significa que essa abordagem é ideal para prever com antecedência pacientes de alto risco e um número mínimo de equipamentos de ventilação e de leitos críticos.

resumo: Esta pesquisa propõe analisar a distribuição de momentos fletores devido à carga móvel entre longarinas de pontes curvas de concreto armado que passaram por um processo de alargamento da superestrutura. Como principais conclusões foi constatado que a redistribuição de momentos é tanto mais significativa quanto mais elevada for a rigidez dos alargamentos. Ademais também foi observado que a redistribuição induzida pela variação da rigidez está condicionada à posição do carregamento móvel, porém, em geral, resultam na migração de esforços para os trechos mais rígidos, aliviando as longarinas originais. Constatou-se ainda que a variação da curvatura pouco altera a redistribuição de esforços induzida pelo aumento da rigidez no alargamento. Ademais, as divergências entre os resultados do MEF e do Método V-Load para os modelos com rigidez variável não divergiram significativamente daqueles obtidos nos modelos de rigidez constante. Por fim, os Fatores de Modificação (FM) mostraram-se mais sensíveis à variação do raio de curvatura do que à resistência do concreto nos alargamentos.

abstract: The study proposes to analyze the distribution of bending moment due to live load in curved bridges that have undergone a process of widening, considering the influence of concrete’s strength variation. The results show that the bending moment redistribution is more significant the higher the stiffness in the widenings. In addition, the redistribution induced by the variation of stiffness depends on the live load positioning but, generally, it results in the migration of bending moments to the stiffer regions, relieving the original girders. The curvature did not significantly alter the response induced by the stiffening of the widened segments. Also, the divergences found between the MEF and the V-load Method results for models with uniform and variable stiffness were similar. Finally, the Modification Factors (MF) proved to be more sensitive to the influence of curvature than to the concrete strength in the widenings.

resumo: o presente estudo foca na análise paramétrica comparativa de pontes curvas utilizando utilizando longarinas retas e curvas pré-moldadas. As análises foram baseadas na distribuição transversal de momento fletor para a longarinas, na variação da curvatura da ponte e na relação desses parâmetros com os resultados obtidos em uma ponte reta. Foram desenvolvidos FEM 3D models com restrições nas posições transversais da carga-móvel e com dois tipos diferentes de modelos de carga: HL-93 e NBR 7187. Os resultados da análise paramétrica foram determinados utilizando o Fator de Modificação (FM) e o Fator de Distribuição de Momento Fletor (FDMF), calculadas a partir da análise estrutural de cada modelo na posição longitudinal do meio do vão. No âmbito global, contatou-se um aumento do momento fletor total nos modelos de ponte curva em relação à reta. Nos exemplos estudados, quanto maior o raio de curvatura, maior foi o momento fletor máximo no meio do vão da ponte. O valor de FM varia linearmente. Para as longarinas externas o FM aumenta com o aumento do L/R, já para as internas, o FM diminui com o aumento do L/R. Além disso, foi comprovada a ocorrência de “Load Shift” diferente do comportamento de corpo rígido, tendo em vista a variação diferenciada de momento fletor para a longarina externa G1 em relação a sua adjacente G2. Constatou-se uma diferença considerável de comportamento estrutural entre as longarinas retas e curvas, tendo em vista que nas SG ocorreu uma diferença significativa de FDMF entre a longarina G1 e a G2 para todas as curvaturas, o que não ocorreu para as CG. Para L/R=0.6, observou-se uma diferença de 17.8% no FDMF entre as longarinas G1 e G2 retas, já nas longarinas curvas, a diferença foi de apenas 6.6%.

abstract: The present study focuses on comparative parametric analysis of curved precast concrete bridges using straight and curved I-girders. The live load bending moment distribution for girders was studied using the bridge curvature and its relationship with the results obtained for a straight bridge. FEM 3D models were developed with restrictions on the transverse live load positions and with two different load models types: HL-93 (AASHTO) and TB-450 (NBR 7188, 2013). The parametric analysis results were calculated using the Modification Factor (MF) and the Bending Moment Distribution Factor (BMDF), calculated from the structural analysis of each model at the midspan. Globally, an increase was found in the total bending moment for the curved bridge models in relation to the straight bridge. In the examples herein studied, the larger the bending radius, the larger the maximal bending moment in the bridge center. For the external girders, the MF increases with the increase of the L/R. For the internal ones, the MF decreases with the increase of the L/R. In addition, the occurrence of “Load Shift” was different from the rigid body behavior, for there was demonstrated a different bending moment variation between external girder (G1) in relation to its adjacent (G2). Therefore, the structural behavior of straight (SG) and curved girders (CG) was analyzed, revealing that, in the SG, a significant gap occurred in the BMDF between G1 and G2 girders for all curvatures. For L/R = 0.6, it caused a difference of 17.8% in the BMDF between the G1 and G2 girders, while on the curved girders, a difference of only 6.6% was found.

Resumo A pulverização de herbicidas sobre a rebrota do eucalipto é uma prática comum no setor florestal. Entretanto, observa-se a necessidade de várias operações em uma mesma área para controle das brotações. Objetivou-se avaliar a eficiência dos herbicidas glyphosate e imazapyr, aplicados no fuste principal antes do corte raso das árvores, no controle de brotações de eucalipto. Foram implantados sete tratamentos representados por doses de 3,0; 4,0 e 5,0 mL/fuste de glyphosate (Gli-Up® 360 g i.a L-1) e das doses de 0,3; 0,5 e 0,7 mL/fuste de imazapyr (Chopper Florestal® 250 g i.a. L-1), além de um tratamento-testemunha. A aplicação dos herbicidas foi realizada em inserções feitas nos fustes das árvores. Aos 30 dias após aplicação dos herbicidas, realizou-se o corte das árvores. Aos 150 dias após o corte das árvores, foram realizadas avaliações do número de brotações por cepa, número de cepas com presença de brotações, altura e a eficiência de controle das brotações. A aplicação de glyphosate promoveu redução do vigor das brotações. Porém, observou-se emissão de brotações em pelo menos 80% das cepas avaliadas. A aplicação da dose de 3 mL de glyphosate promoveu porcentagens de 80% de eficiência de controle. Contudo, observou-se que operações de controle adicionais seriam necessárias. A aplicação de imazapyr mostrou-se ineficiente com controle inferior a 25%. Portanto, conclui-se que a aplicação de glyphosate no fuste da árvore em pré-corte reduz o vigor de brotações de eucalipto. Adicionalmente, a aplicação de imazapyr, nas doses e forma de aplicação testadas, não é recomendada para controle de brotações de eucalipto.

Abstract Herbicide spraying on eucalyptus regrowth prior to planting reform is a common practice in the forest sector. However, several operations are needed in the same area for an effective sprout control. The objective of this work was to evaluate the efficiency of the herbicides glyphosate and imazapyr, applied to the main stem before the harvesting of the tree to eucalyptus sprouts control. There were set up 7 treatments, with application of doses of 3.0; 4.0; and 5.0 mL/stem of glyphosate (Gli-Up® 360g i.a L-1) and doses of 0.3; 0.5; and 0.7 mL/stem of imazapyr (Chopper Florestal® 250g i.a. L-1), in addition to a control treatment. The herbicide spraying consisted of the directed spraying of the herbicides on incisions carried out on the stem of the trees. The harvest of the trees was carried out 30 days after the herbicide spraying. Assessments about the number of sprouts per stump were carried out, the number of stump with presence of coppice, height and control efficiency of the coppice 150 days after harvesting. The glyphosate spraying promoted reduction of the sprout development and vigor. However, even with this reduction, it was observed presence of sprouts in at least 80% of the assessed stumps. The spraying of the dose of 3 mL of glyphosate promoted values next to 80% of control efficiency. Nevertheless, it was observed that new control operations would be necessary. The spraying of imazapyr was inefficient with control efficiency values less than 25%. In conclusion, the application of glyphosate to the main stem before the harvesting of the tree presents reduction in the eucalyptus sprout development. Additionally, the application of imazapyr, in the doses and form application tested, is not recommended to eucalyptus sprout control.

ABSTRACT Purpose: To describe penile fracture (PF) findings with non-sexual etiology in a referral emergency hospital, with emphasis on demographic data, clinical and intraoperative findings and long-term outcomes. Materials and Methods: Patients with PF of non-sexual cause operated at our institution from January 2014 to January 2019 were submitted to surgical treatment and monitored for at least three months after surgery. Etiology of trauma, epidemiological and clinical presentation data, time to intervention and operative findings were reviewed retrospectively. The evaluation of postoperative erectile function was carried out by filling out the International Index of Erection Function - 5 (IIEF-5). The tool used to assess urinary function was the International Prostate Symptom Score (IPSS) questionnaire. Results: Of a total of 149 patients submitted to surgical treatment for PF, 18 (12%) reported non-sexual etiology. Twelve (66.6%) cases were due to penile manipulation through the act of bending the penis during morning erection, three (16.6%) when rolling over in bed with erect penis, one (5.5%) when embracing the wife during erection, one (5.5%) to laying on the partner with erect penis and the other (5.5%) when sitting on the toilet with an erection. Operative findings were unilateral corpus cavernosum injury in all cases. Only one (5.5%) patient had a partial urethral lesion. Follow-up time varied from 3 to 18 months (mean, 10.1 months). Three (16.6%) patients developed erectile dysfunction six months after surgery. However, all of them responded to treatment with IPDE-5 and reported improvement of erection, with no need for medication, on reevaluation after 18 months. One (5.5%) patient developed penile curvature < 30 degrees. Thirteen (72.2%) patients developed penile nodules. No patient presented voiding complaints during follow-up. Conclusions: PF is a rare urologic emergency, especially with the non-sexual etiology. However, PF should always be considered when the clinical presentation is suggestive, regardless of the etiology. Penile manipulation and roll over in bed were the most common non-sexual causes. These cases are related to low-energy traumas, usually leading to unilateral rupture of corpus cavernosum. Urethral involvement is uncommon but may be present. Early treatment has good long-term clinical outcome, especially when performed in specialized centers with extensive experience in FP.

RESUMO: Este artigo analisa o comportamento estrutural de blocos de concreto armado sobre estacas como fundações de aerogeradores onshore por meio de oito modelos baseados no Método dos Elementos Finitos. Foram adotadas como variáveis: o tipo de elemento finito utilizado; o tipo de representação do solo; e, a consideração ou não da resistência do solo sob a base do bloco. Os materiais foram tratados com modelos constitutivos de comportamento elástico linear. Os resultados de interesse foram: reações nas estacas; divisão do carregamento entre o solo e as estacas; deslocamento do bloco; tensões normais radiais e momentos fletores no bloco. Na comparação entre os modelos em elementos sólidos e elementos de casca foi observado que houve boa compatibilidade entre os valores encontrados, tais como divisão do carregamento entre solo e estacas. Em alguns modelos, as análises numéricas revelaram resultados que podem ser contra a segurança estrutural da fundação, quando não se considera a presença do solo sob a base do bloco.

ABSTRACT: This paper analyzes the structural behavior of reinforced concrete pile caps as onshore wind turbine foundations using eight models based on the finite element method (FEM). The variables adopted are: the type of finite element utilized; the soil representation; and, considering or not the soil under the pile cap base. All materials constituting the models were considered as linear elastic behavior. The results of interest are: reaction in piles; dividing the load between soil and piles; pile cap displacement; normal radial stress and bending moments in the pile cap. The models designed on solid elements and shell elements demonstrated good compatibility between the found values, such as dividing the load between soil and piles. In some models, the numerical analysis showed results against the structural safety of the foundation when the soil under the pile cap is not considered.

resumo: O presente estudo realiza uma avaliação crítica de critérios de projeto convencionalmente utilizados, consistindo em uma análise dos efeitos causados pela sequência construtiva, ou seja, incremento gradativo de carregamento e rigidez dos elementos com a evolução da construção, e pela interação solo-estrutura (ISE), representando o solo por molas lineares, em um edifício de alvenaria estrutural sobre estrutura de transição em concreto armado. Foi utilizado o modelo de barras equivalentes, desenvolvido por Nascimento Neto, para discretização da estrutura de transição e do primeiro pavimento em alvenaria, e o modelo de pórtico tridimensional específico para discretização dos demais pavimentos. Mediante quatro modelos de análises, foram avaliadas as distribuições das tensões na base das paredes, e os esforços e deslocamentos da estrutura de transição. Os resultados evidenciam que a introdução da ISE e do efeito construtivo provocam alívio ou possível necessidade de reforço em elementos dimensionados no Estado Limite Último (ELU) e no Estado Limite de Serviço (ELS), assim como uniformização de recalques.

abstract: The present study assesses conventionally used design standards, analyzing the effects caused by the construction loads, that is, a gradual increase in load and stiffness during construction, and soil-structure interaction (SSI), with soil represented by linear springs, in a structural masonry building over a support structure of reinforced concrete. The equivalent frame model, developed by Nascimento Neto, was used to simulate the support structure and the first masonry floor, and a specific three-dimensional frame model to simulate the other floors. Four analysis models were applied to assess stress distribution at the base of the walls, and the stresses and displacements of the support structure. The results show that introducing SSI and the construction loads causes relief or the possible need to reinforce elements designed in Ultimate Limit State (ULS) and Serviceability Limit State (SLS), as well as uniform settlement.

ABSTRACT Objective: To report our experience over the past 20 years in the diagnosis and surgical treatment of penile fracture (PF). Materials and methods: Between January 1997 and January 2017, patients with clinical diagnosis of PF were admitted to our facility and retrospectively assessed. Medical records were reviewed for clinical presentation, etiology and operative findings. Postoperative complications, sexual and urinary function were evaluated. Results: Sexual trauma was the main etiological factor, responsible for 255 cases (88.5%): 110 (43.1%) occurred with the “doggy style” position, 103 (40.3%) with “man on top” position, 31 (12.1%) with the “woman on top” position and 11 (4.3%) in other sexual positions. The most common findings in the clinical presentation were hematoma, in all cases and detumescence in 238 (82.6%). Unilateral corpus cavernosum injuries were found in 199 (69%) patients and bilateral in 89 (31%) patients. Urethral injuries were observed in 54 (18.7%) cases. Nine (14.7%) patients developed erectile dysfunction and eight (13.1%) had penile curvature. Only two (3.7%) patients had complications after urethral reconstruction. Conclusions: PF has typical clinical presentation and no need for additional tests in most cases. Hematoma and immediate penile detumescence are the most common clinical findings. Sexual activity was the most common cause. The ‘doggy style’ and ‘man-on-top’ was the most common positions and generally associated with more severe lesions. Concomitant urethral injury should be considered in cases of highenergy trauma. Surgical reconstruction produces satisfactory results, however, it can lead to complications, such as erectile dysfunction and penile curvature.

ABSTRACT Objective To present the evolution and the recent data on the etiology, diagnosis, management and outcomes of penile fracture (PF) with concomitant urethral injury. Materials and Methods We searched the Pubmed database between 1998 and 2019 using the following key words: “penile fracture”, “fracture of penis”, “trauma to penis”, “rupture of corpora cavernosa”, “urethral injury”, “urethral rupture” and “urethral reconstruction”. Results The incidence of urethral lesion in patients with PF varies by geographic region and etiology. Blood in the meatus, hematuria and voiding symptoms are highly indicative of urethral rupture. The diagnosis of PF is eminently clinical and complementary exams are not necessary. The treatment consists of urethral reconstruction and the most common complications found are urethral stenosis and urethrocutaneous fistula. Conclusion PF is an uncommon urological emergency, particularly in cases with urethral involvement. Urethral injury should be suspected in the presence of suggestive clinical signs, and diagnosis is usually clinical. Urgent urethral reconstruction is mandatory and produces satisfactory results with low levels of complications.

Resumo O conceito de Logística 4.0 é análogo ao da Indústria 4.0. Enquanto a Indústria 4.0 propõe uma mudança disruptiva na manufatura, a Logística 4.0 defende uma transformação na forma como as organizações compram, fabricam, vendem e entregam produtos. O objetivo deste artigo é identificar, nas empresas brasileiras, o grau de interesse no investimento em seis tecnologias emergentes aplicáveis à logística, de acordo com a literatura científica, bem como identificar a percepção atual da qualidade dos dados dessas empresas. Para atingir esses objetivos, foi realizada uma pesquisa online. A pesquisa mostrou que as tecnologias que mais interessam às empresas brasileiras são Internet das Coisas (IoT) e computação em nuvem, ambas com 82% de intenção de investimento. As duas tecnologias que menos interessam às empresas são crowdsourcing e impressão 3D, ambas com desinteresse de 68% pelos investimentos dos entrevistados.

RESUMO: Investigou-se a participação das mulheres nas práticas de criação animal em contextos de transição agroecológica, refletindo sobre os avanços e desafios na superação das desigualdades de gênero no meio rural. Realizaram-se entrevistas semiestruturadas e observação participante em nove propriedades de três municípios da Zona da Mata Mineira. As mulheres atuam na criação de diferentes espécies animais, participando do manejo, processamento e comercialização de produtos, contribuindo para diversificação dos alimentos, autoconsumo e geração de renda. A superação das desigualdades de gênero no contexto da agroecologia implica na visibilização do trabalho, conhecimento e protagonismo da agricultora, com a valorização econômica e acesso ao mercado através de políticas públicas coerentes com a realidade da produção animal na agricultura familiar agroecológica.

ABSTRACT: This study investigated the engagement of women in animal husbandry in agroecological transitions scenarios and reflects on the advancements and challenges encountered in overcoming gender inequalities in rural areas. Semi-structured interviews and participant observation were conducted in nine properties in three municipalities in the region of Zona da Mata of Minas Gerais State. Women are involved in husbandry of different animal species, and participate in the management, processing, and marketing of products, contributing to food diversification, self-consumption, and income generation. Overcoming gender inequality in an agroecological scenario requires making the work and knowledge of women farmers visible and increasing their prominence, while ensuring economic valuation of their work and access to the market through public policies aligned with the reality of animal production in agroecological family agriculture contexts.
