ABSTRACT: This study evaluated the effect of the co-feeding (C) period on the growth and survival of larvae of the yo-yo loach Botia lohachata ornamental species during the weaning period from live food (LF) to inert food (IF). The breeders were subjected to induced spawning using crude pituitary homogenate. A total of 2,400 larvae were used with an average initial weight of 0.39 ± 0.09 mg and an average total length of 4.08 ± 0.21 mm, from a single breeding pair. The live food was newly hatched nauplii of Artemia franciscana, and the inert diet was a commercial ration with 55% crude protein and two particle sizes (142-350 µm and 350-500 µm). As the first food, all larvae received A. franciscana during the first six days, except for the fasting (NC) and inert food (IF) groups. The following co-feeding strategies were employed: C4 = 4 days of co-feeding, C8 = 8 days of co-feeding, C12 = 12 days of co-feeding, and LF = Artemia during the entire experimental period. The longest period with live food promoted better larval growth rates. The specific growth rate of larvae fed live food during the entire period (LF) was higher than that of the other groups, followed by the co-feeding strategies. There was no effect (P > 0.01) on larval survival in the LF, C12, C8, and C4 groups, which ranged from 41% to 53% after 30 days. Treatment R resulted in high mortality and low growth, suggesting that live food should be the first food source for B. lohachata larvae. ABSTRACT cofeeding co feeding C (C yoyo yo (LF IF.

RESUMO: Este estudo teve como objetivo avaliar o efeito do período de co-alimentação (C) no crescimento e sobrevivência de larvas da espécie ornamental Botia lohachata durante o período de desmame de alimento vivo (LF) para alimento inerte (IF). Os reprodutores foram submetidos à desova induzida com homogeneizado de hipófise. Foram utilizadas 2.400 larvas com peso inicial médio de 0,39 ± 0,09 mg e comprimento total médio de 4,08 ± 0,21 mm, de um único casal reprodutor. O alimento vivo foi náuplios recém-eclodidos de Artemia franciscana, e a dieta inerte foi uma ração comercial com 55% de proteína bruta e dois tamanhos de partículas (142-350 µm e 350-500 µm). Como primeiro alimento, todas as larvas receberam A. franciscana durante os primeiros seis dias, exceto os grupos jejum (NC) e alimento inerte (IF). As seguintes estratégias de co-alimentação foram empregadas: C4 = 4 dias de co-alimentação, C8 = 8 dias de co-alimentação, C12 = 12 dias de co-alimentação e LF = Artemia durante todo o período experimental. O maior período com alimento vivo promoveu melhores taxas de crescimento larval. A taxa de crescimento específico das larvas alimentadas com ração viva durante todo o período (LF) foi maior que a dos demais grupos, seguida das estratégias de co-alimentação. Não houve efeito (P > 0,01) na sobrevivência larval nos grupos LF, C12, C8 e C4, que variou de 41% a 53% após 30 dias. O tratamento IN resultou em alta mortalidade e baixo crescimento, sugerindo que o alimento vivo deve ser a primeira fonte de alimento para as larvas de B. lohachata.

ABSTRACT. Combinations between crop intercropping and forage production in a no-tillage system are not well established for environments under low water retention and soil fertility conditions. Our study aimed to evaluate the potential interactions between soybean-grass intercropping with residual nitrogen in a no-tillage system. The experimental design was a randomized block with four replications in a subdivided plot scheme. The main plots in the summer season were: 1) soybean monoculture; 2) soybean - Aruana Guinea grass (Megathyrsus maximus cv. Aruana) intercropping, and 3) soybean - Congo grass (Urochloa ruziziensis cv. Comum) intercropping. The subplots were the nitrogen rates of 0, 50, 100, and 150 kg ha-1, applied as side-dressing in maize and grasses during the autumn-winter season. Here, the results of the summer seasons are shown. To do so, the parameters evaluated were soybean agronomic traits, dry biomass production, and macronutrient concentrations of plants intercropped. The main effects and interactions were studied. Our findings showed that soybean-Aruana Guinea grass intercropping is an alternative to no-tillage system implementation. Moreover, residual nitrogen from the autumn-winter season directly interfered with the dry biomass production of grasses intercropped with soybeans in the summer season. In short, the systems studied seem suitable for implementing a no-tillage system, which aims to neutralize degraded pastures and produce forage for ensilage. Despite the changes in macronutrient concentrations within the intercropping system and residual nitrogen, and among intercropped crops over the years, Congo grass intercropped with soybeans in the summer season showed great capacity for phosphorus, potassium, and magnesium cycling.

Abstract Grain boundaries are fundamental in the mechanical behavior of ultrafine grain materials, especially coincidence site lattice grain boundaries (CSL-GB). This research aims to identify the influence of CSL-GB on the hardness and electrical conductivity of a CuCrZr alloy subjected to rotary swaging after having undergone severe plastic deformation via equal channel angular pressing and aging. Vickers hardness was evaluated, and electrical conductivity was measured using the 4-point technique. The average grain size and CSL-GB distribution were identified using backscattered electron diffraction. Dislocation density was measured via X-ray diffraction. At the end of the swaging processing of CuCrZr alloy with preexistent ultrafine grains, the dislocation density ceases to be the significant influencer parameter on the modification of properties, and the grain boundaries pass to be more impacting. The reduction of CSL-GB and the concomitant increase in high-angle grain boundaries can decrease hardness and electrical conductivity. materials CSLGB. CSLGB CSL GB .

RESUMO Objetivo As infecções sexualmente transmissíveis (IST) afetam desproporcionalmente as mulheres trans e travestis (MTT), que muitas vezes não têm acesso a cuidados de saúde devido ao estigma e à discriminação. Descrevemos a abordagem e a metodologia de um estudo que investigou a prevalência de sífilis, HIV, hepatite A, B e C, Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT) e papilomavírus humano (HPV) entre as MTT, bem como seu conhecimento e percepção sobre a sífilis, para melhor as políticas para redução de IST nessa população vulnerável. Métodos: TransOdara foi um estudo multicêntrico, transversal, realizado em cinco capitais das principais regiões brasileiras entre dezembro de 2019 e julho de 2021. Mulheres autoidentificadas como mulheres trans ou travestis, com idade >18 anos, foram recrutadas usando respondent-driven sampling, após uma fase de pesquisa formativa. Responderam a um questionário conduzido por entrevistadoras. Foi oferecida consulta médica, com exame físico, e solicitou-se que fornecessem amostras de vários locais para detectar as IST citadas. Quando indicado e consentido, foram iniciadas a vacinação e o tratamento. Resultados: Foram recrutadas 1.317 participantes nos cinco locais de estudo: Campo Grande (n=181, 13,7%), Manaus (n=340, 25,8%), Porto Alegre (n=192, 14,6%), Salvador (n= =201, 15,3%) e São Paulo (n=403, 30,6%). O período de recrutamento variou em cada local em razão de restrições logísticas impostas pela pandemia de COVID-19. Conclusão: Apesar dos enormes desafios colocados pela ocorrência simultânea da pandemia da COVID-19 e do trabalho de campo dirigido a uma população vulnerabilizada e dispersa, o projeto TransOdara foi eficazmente implementado. As adversidades não impediram que mais de 1.300 mulheres trans e travestis tenham sido entrevistadas e testadas em meio a uma epidemia de tal magnitude que perturbou os serviços de saúde e os projetos de pesquisa no Brasil e no mundo.

ABSTRACT Objective Sexually transmitted infections (STIs) disproportionately affect transgender women and travestis (TGW), who often lack access to healthcare due to stigma and discrimination. We describe the approach and methodology of a study investigating the prevalence of syphilis, HIV, hepatitis A, B, and C, Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), and human papillomavirus (HPV) among TGW, as well as their knowledge and perceptions regarding syphilis, to better inform policies to curb STIs among this vulnerable population. Methods: TransOdara was a multicentric, cross-sectional study conducted among TGW in five capital cities from major Brazilian regions between December 2019 and July 2021. Self-identified transgender women and travestis aged >18 years were recruited using respondent-driven sampling after a qualitative formative phase, completed an interviewer-led questionnaire, were offered a physical examination, and were also asked to provide samples from multiple sites to detect various STIs, starting vaccination and treatment when indicated. Results: A total of 1,317 participants were recruited from the five study locations: Campo Grande (n=181, 13.7%), Manaus (n=340, 25.8%), Porto Alegre (n=192, 14.6%), Salvador (n=201, 15.3%), and São Paulo (n=403, 30.6%). The recruitment period varied at each study location due to logistic constraints imposed by the COVID-19 pandemic. Conclusion: Despite the enormous challenges posed by the co-occurrence of the COVID-19 pandemic and field work targeting a vulnerable, elusive, and scattered population, the TransOdara project has been effectively implemented. Caveats did not preclude 1,300 TGW from being interviewed and tested, amid a significant epidemic that disrupted health services and research projects in Brazil and worldwide.

ABSTRACT Background Ventilator-associated tracheobronchitis is a common condition among invasively ventilated patients in intensive care units, for which the best treatment strategy is currently unknown. We designed the VATICAN (Ventilator-Associated Tracheobronchitis Initiative to Conduct Antibiotic Evaluation) trial to assess whether a watchful waiting antibiotic treatment strategy is noninferior to routine antibiotic treatment for ventilator-associated tracheobronchitis regarding days free of mechanical ventilation. Methods VATICAN is a randomized, controlled, open-label, multicenter noninferiority trial. Patients with suspected ventilator-associated tracheobronchitis without evidence of ventilator-associated pneumonia or hemodynamic instability due to probable infection will be assigned to either a watchful waiting strategy, without antimicrobial administration for ventilator-associated tracheobronchitis and prescription of antimicrobials only in cases of ventilator-associated pneumonia, sepsis or septic shock, or another infectious diagnosis, or to a routine antimicrobial treatment strategy for seven days. The primary outcome will be mechanical ventilation-free days at 28 days, and a key secondary outcome will be ventilator-associated pneumonia-free survival. Through an intention-to-treat framework with a per-protocol sensitivity analysis, the primary outcome analysis will address noninferiority with a 20% margin, which translates to a 1.5 difference in ventilator-free days. Other analyses will follow a superiority analysis framework. Conclusion The VATICAN trial will follow all national and international ethical standards. We aim to publish the trial in a high-visibility general journal and present it at critical care and infectious disease conferences for dissemination. These results will likely be immediately applicable to the bedside upon trial completion and will provide information with a low risk of bias for guideline development.

RESUMO Contexto A traqueobronquite associada ao ventilador é uma condição comum entre pacientes ventilados invasivamente em unidades de terapia intensiva, para a qual se desconhece atualmente a melhor estratégia de tratamento. Desenhamos o estudo VATICAN (Ventilator-Associated Tracheobronchitis Initiative to Conduct Antibiotic Evaluation) para avaliar se uma estratégia de tratamento antibiótico de espera vigilante não é inferior ao tratamento antibiótico de rotina para traqueobronquite associada ao ventilador em relação aos dias sem ventilador mecânico. Métodos O VATICAN é um estudo randomizado, controlado, aberto e multicêntrico de não inferioridade. Os pacientes com suspeita de traqueobronquite associada ao ventilador sem evidência de pneumonia associada ao ventilador ou instabilidade hemodinâmica devido a uma provável infecção serão designados para uma estratégia de espera vigilante, sem administração profilática de antimicrobianos contra traqueobronquite associada ao ventilador e prescrição de antimicrobianos somente em casos de pneumonia associada ao ventilador, sepse ou choque séptico, ou outro diagnóstico infeccioso, ou para uma estratégia de tratamento antimicrobiano de rotina por 7 dias. O desfecho primário será o número de dias sem ventilador mecânico em 28 dias, e um desfecho secundário importante será a sobrevida sem pneumonia associada ao ventilador. Por meio de uma estrutura de intenção de tratar com análise de sensibilidade por protocolo, a análise do desfecho primário abordará a não inferioridade com margem de 20%, o que se traduz em uma diferença de 1,5 dia sem ventilador. Outras análises seguirão uma estrutura de análise de superioridade. Conclusão O VATICAN seguirá todos os padrões éticos nacionais e internacionais. O objetivo é publicar o estudo em um periódico geral de alta visibilidade e apresentá-lo em conferências de cuidados intensivos e doenças infecciosas para divulgação. Estes resultados provavelmente serão imediatamente aplicáveis à beira do leito após a conclusão do estudo e fornecerão informações com baixo risco de viés para o desenvolvimento de diretrizes. intensiva VentilatorAssociated Ventilator Associated Evaluation randomizado controlado séptico infeccioso 2 protocolo 20 20% 15 1 5 1, superioridade internacionais apresentálo apresentá lo divulgação diretrizes

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 The article discusses the opposition between public spaces and spaces of mobility based on the analysis of political performances during demonstrations that took place in the cities of Belo Horizonte and Rio de Janeiro in Brazil, between 2011 and 2014, years that preceded the sporting mega-events in the two cities. From the comparative and quantitative analysis of journalistic news, we identified the role of mobility as a central element in how political agendas were constructed in the local public sphere, regarding the construction of agendas and the creation of a spatiality for the structuring of political repertoires. Results indicate that public spaces of mobility became spaces where order was contested, while mobile practices became performances that aimed to produce ruptures in flows to produce visibility for political agendas. However, we found differences in the use of public spaces in Rio de Janeiro and Belo Horizonte, especially in terms of the number of demonstrations, the types of agents and the strategies used in demonstrations. Preliminary results suggest that the opposition between these forms of spatiality is quite fragile in understanding contemporary political manifestations.

Resumo O artigo discute a oposição entre espaços públicos e espaços de mobilidade a partir da análise das performances políticas durante manifestações que ocorreram nas cidades de Belo Horizonte e Rio de Janeiro no ciclo de protestos entre 2011 e 2014, no Brasil, período que antecedeu os megaeventos esportivos nas duas cidades. A partir da análise comparada e quantitativa de notícias jornalísticas, identificamos o papel da mobilidade como um elemento central na constituição de uma esfera pública local no que se refere à construção de agendas e na construção de uma espacialidade para a estruturação dos repertórios políticos. Os resultados indicam que os espaços públicos da mobilidade se transformaram em lugares de contestação da ordem, enquanto as práticas móveis se tornaram performances que visavam produzir rupturas nos fluxos para produzir visibilidade para as pautas políticas. No entanto, encontramos diferenças no uso dos espaços públicos cariocas e belo-horizontinos, especialmente em termos do número de manifestações, os tipos de agentes e das estratégias acionadas nos protestos. Indicações iniciais parecem evidenciar que a dicotomia entre estas formas de espacialidade é bastante frágil na compreensão das manifestações políticas contemporâneas.

ABSTRACT Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related mortality worldwide. The Brazilian Society of Hepatology (SBH) published in 2020 the updated recommendations for the diagnosis and treatment of HCC. Since then, new data have emerged in the literature, including new drugs approved for the systemic treatment of HCC that were not available at the time. The SBH board conducted an online single-topic meeting to discuss and review the recommendations on the systemic treatment of HCC. The invited experts were asked to conduct a systematic review of the literature on each topic related to systemic treatment and to present the summary data and recommendations during the meeting. All panelists gathered together for discussion of the topics and elaboration of the updated recommendations. The present document is the final version of the reviewed manuscript containing the recommendations of SBH and its aim is to assist healthcare professionals, policy-makers, and planners in Brazil and Latin America with systemic treatment decision-making of patients with HCC.

RESUMO O carcinoma hepatocelular (CHC) é uma das principais causas de mortalidade relacionada a câncer no Brasil e no mundo. A Sociedade Brasileira de Hepatologia (SBH) publicou em 2020 a atualização das recomendações da SBH para o diagnóstico e tratamento do CHC. Desde então, novas evidências científicas sobre o tratamento sistêmico do CHC foram relatadas na literatura médica, incluindo novos medicamentos aprovados que não estavam disponíveis na época do último consenso, levando a diretoria da SBH a promover uma reunião monotemática on-line para discutir e rever as recomendações sobre o tratamento sistêmico do CHC.

SUMMARY OBJECTIVE: This study aimed to evaluate the prevalence of ovarian hyperstimulation syndrome (OHSS) and associated risk factors in patients undergoing fertilization cycles at risk of OHSS (≥15 antral follicles or ≥15 oocytes aspirated) and submitted to cryopreservation of all embryos in the Human Reproduction Service of the Pérola Byington Hospital (Referral Center for Women's Health) in São Paulo, SP, Brazil. METHODS: This cross-sectional, institutional, descriptive study of secondary data from patients’ charts enrolled in the Assisted Reproduction Service of the Pérola Byington Hospital at risk of OHSS after controlled ovarian stimulation and submitted to cryopreservation of all embryos was conducted between January 2015 and September 2017. RESULTS: OHSS occurred in 47.5% of cycles, all with mild severity, and there were no moderate or severe cases of OHSS. CONCLUSION: The cryopreservation of all embryos is associated with a reduction in moderate and severe forms of OHSS. Risk factors for OHSS should be evaluated prior to initiation of treatment, with less intense stimulation protocols accordingly.

ABSTRACT BACKGROUND: Multimorbidity can influence intensive care unit (ICU) admissions and deaths due to coronavirus disease (COVID-19). OBJECTIVE: To analyze the association between multimorbidity, ICU admissions, and deaths due to COVID-19 in Brazil. DESIGN AND SETTING: This cross-sectional study was conducted using data from patients with severe acute respiratory syndrome (SARS) due to COVID-19 recorded in the Influenza Epidemiological Surveillance Information System (SIVEP-Gripe) in 2020. METHODS: Descriptive and stratified analyses of multimorbidity were performed based on sociodemographic, ventilatory support, and diagnostic variables. Poisson regression was used to estimate the prevalence ratios. RESULTS: We identified 671,593 cases of SARS caused by COVID-19, of which 62.4% had at least one morbidity. Multimorbidity was associated with male sex, age 60–70 and ≥ 80 years, brown and black skin color, elementary education and high school, ventilatory support, and altered radiologic exams. Moreover, all regions of the country and altered computed tomography due to COVID-19 or other diseases were associated with death; only the northeast region and higher education were associated with ICU admission. CONCLUSION: Our results showed an association between multimorbidity, ICU admission, and death in COVID-19 patients in Brazil. BACKGROUND (ICU COVID19. COVID19 COVID 19 .

ABSTRACT Objective To investigate the expression of human papillomavirus (HPV), p16, p53, and p63 in non-schistosomiasis-related squamous cell carcinoma of the bladder and to develop an accurate and automated tool to predict histological classification based on clinicopathological features. Methods Twenty-eight patients with primary bladder pure squamous cell carcinoma who underwent cystectomy or transurethral resection of bladder tumor (TURBT) for bladder cancer between January 2011 and July 2017 were evaluated. Clinical data and follow-up information were obtained from medical records. Formalin-fixed, paraffin-embedded surgical specimens were used for immunohistochemical staining for p16, p53, and p63. Human papillomavirus detection was evaluated by PCR. Statistical analysis was performed, and statistical significance was set at p<0.05. Finally, decision trees were built to classify patients’ prognostic features. Leave-one-out cross-validation was used to test the generalizability of the model. Results Neither direct HPV detection nor its indirect marker (p16 protein) was identified in most cases. The absence of p16 was correlated with less aggressive histological grading (p=0.040). The positive p16 staining detection found only in pT1 and pT2 cases in our sample suggests a possible role for this tumor suppressor protein in the initial stages of bladder squamous cell carcinoma. The decision trees constructed described the relationship between clinical features, such as hematuria/dysuria, the level of tumor invasion, HPV status, lymphovascular invasion, gender, age, compromised lymph nodes, and tumor degree differentiation, with high classification accuracy. Conclusion The algorithm classifier approach established decision pathways for semi-automatic tumor histological classification, laying the foundation for tailored semi-automated decision support systems for pathologists.
