ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

Abstract Due to urban population growth, there is increasing pressure to utilize open spaces in urban centers, particularly in challenging areas like watercourses. However, traditional approaches such as canalization and drainage techniques have proven ineffective and unsustainable in the face of climate change challenges. This research aims to analyze the landscapes and multifunctionality of river environments in Angers, France, identifying their functions and historical evolution, considering the population contributions and the impact on quality of life. The research employed a geohistorical analysis to examine the social, economic, and environmental dimensions through the construction of a historical timeline depicting changes in the urban space influenced by the municipality’s watercourses (Quantitative analysis). Additionally, key actors’ actions were captured and discussed through interviews and questionnaires (Qualitative analysis). This comprehensive approach facilitated the analysis of the evolutionary process of urban rivers and the identification of their multifunctional use, contributing to urban sustainability. The implementation of green and blue infrastructures (GBIs) played a significant role in this process, and participatory interventions helped garner public support for reintegrating rivers into the urban landscape. The interviews highlighted that the successful implementation of multifunctional infrastructures relies not only on clear legislation but also on political will and the adoption of sustainable economic alternatives.

Resumo Devido ao crescimento populacional urbano, existe uma pressão crescente para utilizar espaços abertos em centros urbanos, especialmente em áreas desafiadoras como cursos d’água. No entanto, abordagens tradicionais, como canalização e técnicas de drenagem, têm se mostrado ineficazes e insustentáveis diante dos desafios das mudanças climáticas. Esta pesquisa tem como objetivo analisar as paisagens e a multifuncionalidade dos ambientes fluviais em Angers, na França, identificando suas funções e evolução histórica, considerando as contribuições da população e o impacto na qualidade de vida. A pesquisa utilizou uma análise geo-histórica para examinar as dimensões sociais, econômicas e ambientais por meio da construção de uma linha do tempo histórica que retrata as mudanças no espaço urbano influenciadas pelos cursos d’água do município (Análise quantitativa). Além disso, as ações dos principais atores foram capturadas e discutidas por meio de entrevistas e questionários (Análise qualitativa). Essa abordagem abrangente facilitou a análise do processo evolutivo dos rios urbanos e a identificação de seu uso multifuncional, contribuindo para a sustentabilidade urbana. A implementação de infraestruturas verdes e azuis (IVAs) desempenhou um papel significativo nesse processo, e intervenções participativas ajudaram a obter o apoio público para reintegrar os rios à paisagem urbana. As entrevistas destacaram que a implementação bem-sucedida de infraestruturas multifuncionais depende não apenas de legislação clara, mas também de vontade política e adoção de alternativas econômicas sustentáveis.

Abstract The aim of this study was to evaluate the osseointegration of a hydrophilic surface (blasting + acid etching + immersion in isotonic solution) in comparison with that of a control surface (blasting + acid etching) using an experimental model of low-density bone. To perform the study, 24 rabbits were submitted to the installation of 4 implants in the iliac bone bilaterally: 2 implants with a control surface and 2 implants with a hydrophilic surface. The rabbits were euthanized at 2, 4, and 8 weeks after implant installation. After euthanasia, one implant from each surface was used to perform the removal torque analysis, and the other implant was used for the execution of non-decalcified histological sections and evaluation of the bone implant contact (% BIC) as well as the fraction of bone tissue area between the implant threads (% BBT). The implants with a hydrophilic surface presented higher %BIC (42.92 ± 2.85% vs. 29.49 ± 10.27%) and % BBT (34.32 ± 8.52% vs. 23.20 ± 6.75%) (p < 0.05) in the 2-week period. Furthermore, the hydrophilic surface presented higher removal torque in the 8-week period (76.13 ± 16.00 Ncm2 vs. 52.77 ± 13.49 Ncm2) (p<0.05). Implants with a hydrophilic surface exhibited acceleration in the process of osseointegration, culminating in greater secondary stability in low-density bone than in implants with a control surface.

Resumo O objetivo deste estudo foi avaliar a osseointegração de uma superfície hidrofílica (jateamento + ataque ácido + imersão em solução isotônica) em comparação com uma superfície controle (jateamento + ataque ácido) usando um modelo experimental de osso de baixa densidade. Para realizar o estudo, 24 coelhos foram submetidos a instalação de 4 implantes bilateralmente no osso ilíaco: 2 implantes com superfície controle e 2 implantes com superfície hidrofílica. Os coelhos foram eutanasiados com 2, 4 e 8 semanas após a instalação dos implantes. Após a eutanásia, um implante de cada superfície foi usado para avaliar o torque de remoção, e o outro implante foi utilizado para execução de cortes histológicos não descalcificados e avaliação de contato osso implante (% BIC) bem como a fração da área tecido ósseo entre as roscas do implante (% BBT). Os implantes com superfície hidrofílica apresentaram maior %BIC (42.92 ± 2.85% vs. 29.49 ± 10.27%) e % BBT (34.32 ± 8.52% vs. 23.20 ± 6.75%) (p < 0.05) no período de 2 semanas. Além disso, a superfície hidrofílica apresentou maior torque de remoção no período de 8 semana (76.13 ± 16.00 Ncm2 vs. 52.77 ± 13.49 Ncm2) (p<0.05). Implantes com a superfície hidrofílica apresentaram aceleração no processo de osseointregração, culminando em melhor estabilidade secundária no osso de baixa densidade em relação a implantes com superfície controle.

RESUMO OBJETIVO Validar um conjunto de indicadores para monitoramento da qualidade dos procedimentos cirúrgicos no Sistema Único de Saúde (SUS). MÉTODOS Estudo de validação desenvolvido em 5 etapas: 1) revisão de literatura; 2) priorização de indicadores; 3) validação de conteúdo dos indicadores por método de consenso RAND/UCLA; 4) estudo piloto para análise da confiabilidade; e 5) desenvolvimento de instrutivo para tabulação dos indicadores de resultado para monitoramento via sistemas de informações oficiais. RESULTADOS A partir da revisão de literatura, foram identificados 217 indicadores de qualidade cirúrgica. Os indicadores excluídos foram: indicadores baseados em evidências científicas inferiores a 1A, similares, específicos, que correspondiam a eventos sentinelas; e aqueles que não se aplicavam ao contexto do SUS. Foram submetidos ao consenso de especialistas 26 indicadores com alto nível de evidência científica. Foram validados 22 indicadores, dos quais 14 indicadores de processo e 8 indicadores de resultado com índice de validação de conteúdo ≥80%. Dos indicadores de processo validados, 6 foram considerados confiáveis substancialmente (Coeficiente de Kappa entre 0,6 e 0,8; p < 0,05) e 2 tiveram confiabilidade quase perfeita (coeficiente de Kappa > 0,8, p < 0,05), quando analisada a concordância interavaliador. Foi possível mensurar e estabelecer mecanismo de tabulação para TabWin para 7 indicadores de resultado. CONCLUSÃO O estudo contribui com o desenvolvimento de um conjunto de indicadores cirúrgicos potencialmente eficazes para o monitoramento da qualidade do cuidado e segurança do paciente nos serviços hospitalares do SUS.

ABSTRACT OBJECTIVE To validate a set of indicators for monitoring the quality of surgical procedures in the Brazilian Unified Health System (SUS). METHODS Validation study developed in 5 stages: 1) literature review; 2) prioritization of indicators; 3) content validation of indicators by RAND/UCLA consensus method; 4) pilot study for reliability analysis; and 5) development of instruction for tabulation of outcome indicators for monitoring via official information systems. RESULTS From the literature review, 217 indicators of surgical quality were identified. The excluded indicators were: those based on scientific evidence lower than 1A, similar, specific, which corresponded to sentinel events; and those that did not apply to the SUS context. Twenty-six indicators with a high level of scientific evidence were submitted to expert consensus. Twenty-two indicators were validated, of which 14 process indicators and 8 outcome indicators with content validation index ≥80%. Of the validated process indicators, 6 were considered substantially reliable (Kappa coefficient between 0.6 and 0.8; p < 0.05) and 2 had almost perfect reliability (Kappa coefficient > 0.8, p < 0.05), when the inter-rater agreement was analyzed. One could measure and establish tabulation mechanism for TabWin for 7 outcome indicators. CONCLUSION The study contributes to the development of a set of potentially effective surgical indicators for monitoring the quality of care and patient safety in SUS hospital services.

Aim To evaluate the resistance of the union between a glass fiber post and radicular dentine after cleaning the root with 17% EDTA and filling with different endodontic cements. Methods Forty uniradicular bovine incisors were removed to obtain root lengths of 18 mm. Endodontic treatment was performed on all roots using different filling cements (zinc oxide and eugenol-based, OZE; cement based on epoxy resin, AH) and cleaning solutions (saline, SA or EDTA), which made it possible to obtain four groups: OZESA, OZEEDTA, AHSA and AHEDTA. Subsequently, 12 mm of filling material was removed from the roots, and they were prepared to receive fiber posts luted with resin cement. To execute the mechanical cycles (2x106 cycles, 90 N, 4 Hz), coronal reconstruction was performed with a silicon matrix. The roots were then sliced (2-mm thick) to perform the push-out test. The results were analyzed using analysis of variance (one factor and two factors) and Tukey’s test (α=0,05). Results Bond strength (Mpa) was significantly higher for OZEEDTA (9,18) and AHEDTA (8,70) than for OZESA (6,06) AHSA (8,7). OZEEDTA also presented the highest values in the cervical region (15,18) but was significantly lower in the apical region (2,99). However, AHEDTA had a homogeneous bond strength in all thirds. Conclusion Regardless of the endodontic cement used, EDTA was used as an irrigating solution, culminating in a higher bond strength between the glass fiber post and dentin.

RESUMO Esta pesquisa tem como objetivo compreender em que medida ocorrem ações de gaslighting no ambiente de trabalho. Para tal, elaboramos uma pesquisa empírica, na qual visitamos 37 empresas de diferentes portes, no Rio de Janeiro e em São Paulo, e entrevistamos 72 trabalhadores com diversos traços psicográficos. Essas entrevistas e nossas anotações de campo foram submetidas à Análise Crítica de Discurso. Identificamos duas categorias a priori (“gaslighting racial” e “gaslighting misógino”), duas emergentes (“gaslighting LGBTQIAP+-fóbico” e “gaslighting instrumental”), e construímos a axial, denominada “gaslighting pecuniário”. O campo revelou que gaslighting ocorre em todos os tipos de empresas pesquisadas e é uma estratégia de manipulação exercida por homens brancos heterossexuais não só sobre grupos não hegemônicos, mas contra seus pares. Este estudo traz como implicações gerenciais e à teoria a discussão e reflexão sobre como práticas discriminatórias têm sido naturalizadas e marginalizadas, não só no campo de estudos, mas na cultura organizacional.

ABSTRACT This research aims to understand the extent to which gaslighting actions occur in the work environment. To this end, we conducted an empirical survey, in which we visited 37 companies of different sizes, in Rio de Janeiro and São Paulo and interviewed 72 workers of different psychographic traits. These interviews and our field notes were subjected to Critical Discourse Analysis. We identified two categories a priori, (“racial gaslighting” and “misogynistic gaslighting”), two emerging ones (“LGBTQIAP + -phobic gaslighting” and “instrumental gaslighting”) and built the axial, called “pecuniary gaslighting”. The field revealed that gaslighting occurs in all types of companies and is a manipulation strategy exercised by heterosexual white men not only on non-hegemonic groups, but against their peers. This study brings as managerial implications and theory, the discussion and reflection on how discriminatory practices have been naturalized and marginalized, not only in the field of studies, but in the organizational culture.

Abstract As high-voltage circuit breakers (HVCBs) are responsible for switching off the load in the event of anomalies, they suffer various wear and tear, both on their main contacts and on the other actuation mechanisms. Not only load maneuvers but also weather conditions can bring factors that contribute to deterioration and, consequently, contribute to failures of this component that is so important for energy supply. Both failures and maintenance shutdowns generate costs for substations, something that could be minimized if there was monitoring of the condition of the HVCBs. This paper shows a methodology to analyze the vibration signal of HVCB in order to identify and quantify contact failures. The proposed methodology is verified through an experimental setup. The results show that it is possible not only to identify the fault but also to assess its intensity using vibration analysis.

Abstract Background Recent reports in the literature have indicated that infection by coronavirus disease 2019 (COVID-19) causes cardiac complications, such as heart failure, arrhythmia, myocardial infarction, and even fulminant myocarditis. These complications have been identified as the cause of death in some patients infected with SARS-CoV-2. Objectives To analyze echocardiographic and electrocardiographic changes, treatments used, and clinical outcomes in patients with myocarditis and COVID-19. Methods The items described for Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were followed. This review included articles in English, Portuguese, and Spanish that reported cardiac involvement, injury, or myocardial inflammation in patients who acquired COVID-19 (SARS-CoV-2). Results Five databases were consulted to find 1,726 articles. After applying the eligibility criteria, a total of 22 studies were considered qualified. ST-segment (section of the electrocardiogram corresponding the end of the S wave to the beginning of the T wave) elevation and tachyarrhythmia were the most common changes found in the electrocardiographic analysis of patients affected with COVID-19. Concerning echocardiography, there was a high frequency of decreased ejection fraction and occurrence of pericardial effusion. Conclusion This systematic review provides a potential tool for the analysis of cardiac changes and implications caused in patients affected by SARS-CoV-2 infection, with emphasis on the presence of tachyarrhythmia on electrocardiogram (ECG) and decreased ejection fraction on echocardiogram.

ABSTRACT Introduction: Sagittal balance was measured by Hardacker`s et al. using the occipital method COBB C1-C2, C2-C3, C3-C4, C4-C5, C5-C6, C6-C7 in a sample of asymptomatic patients without neck and shoulder pain. In other recent studies, measurements of cervical sagittal balance included several radiographic parameters. Objective: To compare the cervical sagittal balance in groups of patients with and without neck pain submitted to cervical radiography with the upper limbs in flexion. Methods: This is a cross-sectional, quantitative, prospective, descriptive study with radiographic analysis of 50 adults aged between 30 to 70 years old. The group was divided into Group 1: without neck pain, and Group 2: with neck pain. All answered a questionnaire about age and the presence or absence of neck pain. Exclusion criteria were: inadequate X-Ray image, deformity or previous spine surgery, limited shoulder mobility, and individuals younger than 30 and older than 70. The radiographic parameters evaluated were: COBB, TIA ( THORACIC INLET ANGLE), T1 SLOPE, NECKTILT, and COG-C7 with no neck pain. α = 5% (significance when p <0.05). Results: The MANN WHITNEY nonparametric test showed no significant differences between Cobb GROUPS (p= 0.7452), T1 SLOPE GROUPS (p=0.1410), NECKTILT GROUPS (p=0.0852) and GROUPS THORACIC INLET ANGLE (p=0.1789). Conclusion: There was a significant difference only between COG-C7 GROUPS (cm) (p=0.0013). The analysis of the obtained data showed statistical significance in the variation in the COG-C7 groups. Level of Evidence II; Prospective comparative study.

ABSTRACT Background: Determining the basic density of the wood is usually defined as a simple process, but it requires caution and the operator’s skill to avoid errors in the analysis. In addition, it involves sample preparation and time to saturate the wood until obtaining the dry sample mass. The development of alternative measurement techniques could reduce the time to obtain the results and provide reliable values. Therefore, this study aimed to develop multivariate models to estimate the basic density of native woods using near-infrared spectra (NIR). Basic densities were determined by the water immersion method, and the values were associated with NIR signatures. Spectra were directly collected on the wood transversal and radial faces with an integrating sphere. Partial least squares regression (PLS-R) was calibrated and validated to estimate basic density based on spectral signatures. Results: In the cross-validation and prediction of the models, the results were promising. The coefficients of determination varied from 0.87 to 0.93 with a standard error of 0.01 %. The partial least squares discriminant analysis (PLS-DA) efficiently classified the wood species. The ratio of performance to deviation obtained satisfactory values, a minimum of 2.81 and a maximum of 4.20. Conclusion: The statistical parameters of the models based on NIR spectra showed potential for density measurements in floors, furniture, and solid wood products.

Abstract The iAtlantic Project has established an international collaborative strategy to improve mapping and characterization of deep and open ocean ecosystems in understudied regions of the Atlantic and evaluate their health. In December 2022, the first iAtlantic expedition in the South Atlantic set off to map and explore seafloor ecosystems in the Santos Basin slope (200-1,000 m depths) in collaboration with the Petrobras ‘Santos Basin - Regional Characterization Project.’ The 17-day ‘iAtlantic_BR10-Petrobras’ cruise was conducted on board the research vessel NPqHOc Vital de Oliveira (Brazilian Navy) and performed (a) water column structure characterization, (b) seafloor morphology mapping, (c) description of benthic habitats and communities by seafloor imagery and biological/ geological sampling, and (d) ex-situ experiments to assess the functioning of sedimentary ecosystems and their responses to climate-related environmental changes. This study describes the rationale behind the iAtlantic_BR10-Petrobras cruise science plan, reports its sampling strategy and methods, and summarizes its collected data and preliminary results.

In recent years, there has been a growing interest in the search for metallic alloys with favorable mechanical and chemical characteristics that elicit a positive biological response. Among these alloys, β-Ti alloys have attracted significant attention due to their low elastic modulus and excellent biocompatibility. The addition of Nb contributes to stabilizing the β phase at room temperatures, leading to the transformation of β into β + α (β-isomorph). Additionally, despite Zr being commonly considered a neutral element, it can exhibit a β-stabilizing characteristic when combined with betagenic elements. Both Nb and Zr have been shown to effectively increase the lattice parameter of the β phase, which is advantageous for reducing the elastic modulus. The primary objective of this study was to characterize β-Ti alloys within the Ti-Nb-Zr system, specifically Ti-40Nb-20Zr, Ti-40Nb-30Zr, and Ti-40Nb-40Zr (wt.%) produced via arc furnace casting. The study aimed to investigate the influence of the proportion of β-stabilizing or betagenic elements on the microstructure and properties of the alloys, including Vickers microhardness and elastic modulus.

ABSTRACT Objective: to create and validate an app that establishes the diabetic foot risk degree by associating the patients’ health conditions. Methodology: a methodological study conducted between March 2019 and December 2021 in Crato - CE - Brazil, and divided into three phases: 1) Review of the national and international guidelines; 2) Creation of the educational technology; and 3) Face and content validation of the technology. This study followed the guidelines set forth in the Revised Standards for Quality Improvement Reporting Excellence guide. Results: in the review phase, similar content was identified between the guidelines for designing and organizing the content. The technology that was created enabled data collection, as well as diabetic foot risk assessment and classification. A total of 18 judges evaluated the instrument in the validation stage, obtaining a CVI value of 0.96. Conclusion: the study may contribute to improving the indicators referring to hospitalizations, amputations, reduced mobility, dependence, frailty and mortality resulting from diabetic foot.
