Abstract Objective Evaluate the effect of combined training on body image (BI), body composition and functional capacity in patients with breast cancer. As also the relationship of BI with body composition and functional capacity. Methods This was a Controlled Clinical Trial study, this study including 26 patients with breast cancer (30 to 59 years). The training group (n = 13) underwent 12 weeks of training, including three 60-min sessions of aerobic exercise and resistance training, and two sessions of flexibility training per week; each flexibility exercise lasted 20s. The Control Group (n = 13) received only the standard hospital treatment. Participants were evaluated at baseline and after 12 weeks. BI (primary outcomes) was assessed using the Body Image After Breast Cancer Questionnaire; Body composition was estimated with the indicators: Body mass index; Weight, Waist hip Ratio; Waist height ratio; Conicity index; Reciprocal ponderal index; Percentage of fat; Circumference of the abdomen and waist; Functional capacity by cardiorespiratory fitness (cycle ergometer) and strength (manual dynamometer). The statistic was performed in the Biostatistics and Stata 14.0 (α = 5%). Results The patients in the training group showed a reduction in the limitation dimension (p = 0.036) on BI, However, an increase in waist circumference was observed in both groups. In addition an increase in VO2max (p < 0.001) and strength in the right (p = 0.005) and left arms (p = 0.033). Conclusion Combined training demonstrates to be an effective and non-pharmacological strategy to patients with breast cancer, with improvement on BI and functional capacity, changing related variables negatively when there is no physical training.

Abstract Hereditary transthyretin amyloidosis with peripheral neuropathy (ATTRv-PN) is an autosomal dominant inherited sensorimotor and autonomic polyneuropathy with over 130 pathogenic variants identified in the TTR gene. Hereditary transthyretin amyloidosis with peripheral neuropathy is a disabling, progressive and life-threatening genetic condition that leads to death in ~ 10 years if untreated. The prospects for ATTRv-PN have changed in the last decades, as it has become a treatable neuropathy. In addition to liver transplantation, initiated in 1990, there are now at least 3 drugs approved in many countries, including Brazil, and many more are being developed. The first Brazilian consensus on ATTRv-PN was held in the city of Fortaleza, Brazil, in June 2017. Given the new advances in the area over the last 5 years, the Peripheral Neuropathy Scientific Department of the Brazilian Academy of Neurology organized a second edition of the consensus. Each panelist was responsible for reviewing the literature and updating a section of the previous paper. Thereafter, the 18 panelists got together virtually after careful review of the draft, discussed each section of the text, and reached a consensus for the final version of the manuscript.

Resumo Polineuropatia amiloidótica familiar associada a transtirretina (ATTRv-PN) é uma polineuropatia sensitivo-motora e autonômica hereditária autossômica dominante com mais de 130 variantes patogênicas já identificadas no gene TTR. A ATTRv-PN é uma condição genética debilitante, progressiva e que ameaça a vida, levando à morte em ~ 10 anos se não for tratada. Nas últimas décadas, a ATTRv-PN se tornou uma neuropatia tratável. Além do transplante de fígado, iniciado em 1990, temos agora 3 medicamentos modificadores de doença aprovados em muitos países, incluindo o Brasil, e muitas outras medicações estão em desenvolvimento. O primeiro consenso brasileiro em ATTRv-PN foi realizado em Fortaleza em junho de 2017. Devido aos novos avanços nesta área nos últimos 5 anos, o Departamento Científico de Neuropatias Periféricas da Academia Brasileira de Neurologia organizou uma segunda edição do consenso. Cada panelista ficou responsável por rever a literatura e atualizar uma parte do manuscrito. Finalmente, os 18 panelistas se reuniram virtualmente após revisão da primeira versão, discutiram cada parte do artigo e chegaram a um consenso sobre a versão final do manuscrito.

A região do Araguaia foi atravessada por inúmeros conflitos desde a década de setenta que se configuraram como a Guerra do Araguaia. Nesse contexto, objetivamos demonstrar como camponeses dessa região se refizeram das inúmeras violências sofridas e se firmaram na luta por direitos sociais. Para tanto, apresentamos duas entrevistas trabalhadas por análise de conteúdo, evidenciando as diversas violências infringidas pelo Estado e suas formas de superação. Concluímos que o processo de reorganização psicossocial dos diversos traumas sofridos ocorre no campo da individualidade, faltando ainda um reconhecimento coletivo do Estado como repressor. contexto sociais tanto conteúdo superação individualidade repressor

The Araguaia region has been crossed by numerous conflicts since the 1970s, which became known as the Araguaia’s War. In From Witness of the ‘Araguaia War’ to the Struggle for Rights in the Brazilian Amazon, we aim to demonstrate how peasants in this region recovered from the countless violence suffered and established themselves in the struggle for social rights. We present two interviews worked through content analysis, highlighting the various forms of violence inflicted by the State and their ways of overcoming them. We conclude that the process of psychosocial reorganization of the various traumas suffered occurs in the field of individuality, still lacking a collective recognition of the State as a repressor. 1970s s Araguaias War Amazon rights analysis them individuality repressor

Abstract: The use of wood as a bioenergetic source requires knowledge of its technical properties. The rubber tree Hevea brasiliensis has an economic life cycle of 25 to 30 years in Brazil. It is used for extracting rubber and generating residual wood for fuel. Our goal was to characterize the wood quality of 10 clonal progenies as a source of raw material for bioenergy. Ten clonal progenies of 12-year-old Hevea brasiliensis from an experimental planting in Selvíria municipality were evaluated. Three trees per clone were evaluated for individual properties of Higher Heating Value, immediate chemical analysis, chemical composition, fiber dimensions, thermogravimetric analysis of wood under nitrogen atmosphere and Fourier Transform Infrared Spectroscopy analysis. We highlight clone IAC 311 for fuel because it presents elevated Higher Heating Value and fixed carbon and less volatile material. However, the other genetic materials studied also meet the specifications for energy use and can be highly viable given their physical, chemical, energy, and thermal properties.

Abstract The formation of biofilm on denture bases is a recurrent clinical problem that favors the development of denture stomatitis. The effectiveness of a hygiene protocol in a 3D-printed denture base resin is still uncertain. Objective To evaluate of the effectiveness of immersion, associated or not with brushing in a soap solution, on the biofilm control of a 3D-printed denture base resin. Methodology Specimens of denture base resins [Cosmos Denture (COS) and Classico (CLA/control)] were contaminated in vitro with Candida albicans and immersed in sodium hypochlorite 0.25% (SH, alkaline peroxide) AP, chlorhexidine digluconate 2% (CD or PBS-Control), associated or not with brushing with 0.78% Lifebuoy soap. Roughness was evaluated before and after brushing and immersion. The effectiveness of the protocols was assessed by CFU/mL, cellular metabolism (XTT), scanning electron microscopy (SEM), and confocal scanning laser microscopy. Data were analyzed by T student, ANOVA/Welch, and Tukey/Gomes–Howell pos-hoc tests (α = 0.05). Results CLA showed greater roughness than COS. CFU/mL and XTT were higher in COS resin with a higher hyphae formation. Immersion in SH and CD eliminated CFU/mL and reduced XTT for both resins, associated or not with brushing. AP reduced CFU/mL only when associated with brushing. Conclusions The biofilm on the 3D-printed resin was thicker and presumably more pathogenic, regardless of its smoother surface. Immersions in SH 0.25% and CD 2% are effective hygiene protocols for both resins, associated or not with brushing. AP should be recommended when associated with brushing with a Lifebuoy 0.78% solution.

Abstract Objective To present the update of the recommendations of the Brazilian College of Radiology and Diagnostic Imaging, the Brazilian Society of Mastology and the Brazilian Federation of Associations of Gynecology and Obstetrics for breast cancer screening in Brazil. Methods Scientific evidence published in Medline, EMBASE, Cochrane Library, EBSCO, CINAHL and Lilacs databases between January 2012 and July 2022 was searched. Recommendations were based on this evidence by consensus of the expert committee of the three entities. Recommendations Annual mammography screening is recommended for women at usual risk aged 40–74 years. Above 75 years, it should be reserved for those with a life expectancy greater than seven years. Women at higher than usual risk, including those with dense breasts, with a personal history of atypical lobular hyperplasia, classic lobular carcinoma in situ, atypical ductal hyperplasia, treatment for breast cancer or chest irradiation before age 30, or even, carriers of a genetic mutation or with a strong family history, benefit from complementary screening, and should be considered individually. Tomosynthesis is a form of mammography and should be considered in screening whenever accessible and available.

Abstract Objective: To present an update of the recommendations of the Brazilian College of Radiology and Diagnostic Imaging, the Brazilian Society of Mastology, and the Brazilian Federation of Gynecology and Obstetrics Associations for breast cancer screening in Brazil. Materials and Methods: Scientific evidence published between January 2012 and July 2022 was gathered from the following databases: Medline (PubMed); Excerpta Medica (Embase); Cochrane Library; Ebsco; Cumulative Index to Nursing and Allied Health Literature (Cinahl); and Latin-American and Caribbean Health Sciences Literature (Lilacs). Recommendations were based on that evidence and were arrived at by consensus of a joint committee of experts from the three entities. Recommendations: Annual mammographic screening is recommended for women between 40 and 74 years of age. For women at or above the age of 75, screening should be reserved for those with a life expectancy greater than seven years. Women at higher than average risk are considered by category: those with dense breasts; those with a personal history of atypical lobular hyperplasia, classical lobular carcinoma in situ, or atypical ductal hyperplasia; those previously treated for breast cancer; those having undergone thoracic radiotherapy before age 30; and those with a relevant genetic mutation or a strong family history. The benefits of complementary screening are also addressed according to the subcategories above. The use of tomosynthesis, which is an evolved form of mammography, should be considered in screening, whenever accessible and available.

Vanadis®8 is a high-value tool steel, that undergoes gas atomization and hot isostatic pressing during production , resulting in costly waste. Repurposing this waste material through powder metallurgy (PM) offers a cost-effective solution. This study explores the PM process applied to Vanadis®8 steel scraps, involving high energy ball milling, uniaxial pressing, and sintering. The final product and the as-received steel underwent heat treatments, including quenching and tempering. Microstructural evaluation employed X-ray diffraction and scanning electron microscopy, while physical evaluation entailed Archimedes density measurements. Mechanical analysis was carried out through microhardness and compression strength tests. Results revealed that optimal milling conditions were achieved at 30 hours with 400 rpm (s-1). Vanadis®8 steel produced through PM attained 85% densification compared to the as-received material (6.31 g/cm3). MC-type carbides were present in all evaluated conditions. Heat treatments improved mechanical values for all conditions, suggesting that PM-produced Vanadis®8 steel, subjected to quenching and tempering, presents a viable reuse option.

ABSTRACT Objective To describe the radiological characteristics of hepatocellular carcinoma (HCC) lesions that achieved a complete response following drug-eluting bead transarterial chemoembolization (DEB-TACE) preceding liver transplantation. Methods This single-center case-control study enrolled patients with hepatocellular carcinoma who underwent neoadjuvant DEB-TACE therapy, were followed up with contrast-enhanced magnetic resonance imaging or computed tomography, and were successively evaluated according to the modified Response Evaluation Criteria in Solid Tumors. The HCCs were divided into two groups based on their diameter (Group A: ≤3cm; Group B: 3cm). Viability was assessed using the Kaplan-Meier method according to tumor size categories. The relationship between tumor variables was analyzed using bivariate Cox regression. Results Three-hundred and twenty-eight patients with 667 hepatocellular carcinomas who underwent their first DEB-TACE session were enrolled. A total of 105 hepatocellular carcinomas in 59 patients exhibited complete response after the initial DEB-TACE session and were divided into Group A (92 HCCs) and Group B (13 HCCs). The diameter in Group A decreased significantly compared to the pre-procedure size until the second assessment (p<0.001), with no subsequent reduction in diameter, despite maintaining a complete response. In Group B, the reduction in diameter remained significant compared with the initial value until the sixth imaging evaluation (p=0.014). The average reduction was 45.1% for Group B and a maximum of 14.9% in Group A. Conclusion HCCs >3cm exhibited a greater reduction in size and a longer time to recurrence. HCCs ≤3cm had a shorter relapse time. The recurrence rates were similar. These findings may aid in planning for liver transplantation.

Abstract In view of the morphological similarity between gastrointestinal stromal tumors (GIST) and other sarcomas of the intestine of dogs, the aim was to carry out the histomorphological and immunohistochemical diagnosis of these tumors, associating breed, sex and age, location and tumor invasion. 217 cases were evaluated by histopathology and 36 diagnosed by immunohistochemistry were included (24 GIST and 12 other intestinal sarcomas). Mixed breed dogs were the most diagnosed with GIST, mainly elderly females (9.5±2.2 years); in the other intestinal sarcomas, crossbreeds and Dachshunds, males and females, were equally affected. The cecum was the most affected by GISTs, with tumor invasion of the intestinal layers in all cases. The small intestine was the most affected by the other intestinal sarcomas, with invasion of the layers in most of these tumors. GISTs expressed markers such as CD117 and DOG-1, unlike other intestinal sarcomas. GIST and other intestinal sarcomas denoted histomorphological and immunophenotypic characteristics similar to histopathology, justifying the association of immunohistochemistry for the definitive diagnosis.

Resumo Tendo em vista a semelhança morfológica entre tumores estromais gastrointestinais (GIST) e outros sarcomas do intestino de cães, objetivou-se realizar o diagnóstico histomorfológico e imunoistoquímico desses tumores, associando raça, sexo e idade, localização e invasão tumoral. Foram avaliados 217 casos por histopatologia e incluídos 36 diagnosticados por imuno-histoquímica (24 GIST e 12 outros sarcomas intestinais). Cães sem raça definida foram os mais diagnosticados com GIST, principalmente fêmeas idosas (9,5±2,2 anos); nos demais sarcomas intestinais, mestiços e Dachshunds, machos e fêmeas, foram igualmente acometidos. O ceco foi o mais acometido pelos GISTs, com invasão tumoral das camadas intestinais em todos os casos. O intestino delgado foi o mais acometido pelos demais sarcomas intestinais, com invasão das camadas na maioria desses tumores. GISTs expressaram marcadores como CD117 e DOG-1, ao contrário de outros sarcomas intestinais. O GIST e outros sarcomas intestinais denotaram características histomorfológicas e imunofenotípicas semelhantes à histopatologia, justificando a associação da imuno-histoquímica para o diagnóstico definitivo.

ABSTRACT In recent years, a disease called black crust has caused damage to rubber trees in Brazil, since it leads to rapid leaf fall and consequently low latex production. Until the 1990s, black crust was associated with the fungi Phyllachora huberi and Rosenscheldiella heveae, but in 2022, after analysis of samples collected in the states of Minas Gerais and São Paulo, different species of the fungus Cladosporium ssp. were isolated from rubber tree leaves showing black crust in their leaflets. After morphological and phylogenetic analysis, using partial sequences of ITS-5.8S rDNA, α-elongase and actin regions, the isolates were identified as Cladosporium pseudocladosporioides, C. tenuissimum, C. cladosporioides, C. perangustum and C. xanthochromaticum. Pathogenicity tests with these isolates, in a greenhouse, demonstrated rapid appearance of symptoms such as apical death, damage to stems, intense defoliation and presence of black crust on stems and leaves. All isolates were pathogenic but had variable aggressiveness. This is the first report of Cladosporium causing black crust on rubber trees in Brazil.

RESUMO Nos últimos anos, uma doença chamada crosta negra tem causado danos à seringueira no Brasil, pois esta doença causa a rápida queda das folhas e como consequência a baixa produção de látex. Até a década de 1990, a crosta negra era associada aos fungos Phyllachora huberi e Rosenscheldiella heveae, mas em 2022, após análise de amostras coletadas nos estados de Minas Gerais e São Paulo, diferentes espécies do fungo Cladosporium ssp. foram isoladas de folhas com crosta negra em folíolos de seringueira. Após análise morfológica e filogenética, com sequências parciais das regiões ITS-5.8S rDNA, α-elongase e actina, os isolados foram identificados como Cladosporium pseudocladosporioides, C. tenuissimum, C. cladosporioides, C. perangustum e C. xanthochromaticum. Testes de patogenicidade com estes isolados, em casa de vegetação, demonstraram o rápido aparecimento de sintomas como morte apical, danos aos caules, intensa desfolha e presença de crosta negra nos caules e folhas. Todos os isolados foram patogênicos, porém com agressividade variada. Este é o primeiro relato de Cladosporium ssp. causando crosta negra em seringueiras no Brasil.

ABSTRACT The main objective of this study was to evaluate the effects of phenotypic, genotypic, and auction characteristics that may influence the selling prices of bulls. Data from 1,540 Braford and 1,179 Brangus bulls sold at auctions in the state of Rio Grande do Sul, Brazil, were collected and evaluated individually. Body condition score (BCS), muscularity, frame, foreskin size, presence or absence of horns, and data regarding the auction such as name/venue, event edition, forms of payment, among others, were considered. Information such as weight at the time of sale, scrotal circumference (SC), expected profit differences, selection indexes, and date of birth were collected from the catalogs supplied at the auctions. To obtain the influence of the selected explanatory variables throughout the conditional distribution of bull prices, a quantile regression was used, and the quantiles were established as follows: 10th, 25th, 50th, 75th, and 90th. The buyers of Braford and Brangus bulls valued characteristics such as age, weight, and SC in relation to frame, muscularity, BCS, and foreskin size. In addition, the price behavior at different auctions was positively related to the operation time of the auction in this market and with the reputation of the seller. Regarding genetic variables of Brangus bulls, these had little or no influence on the selling price. There was a positive influence on the weaning index in the 90th quantile and on the final index in the 50th and 75th quantiles. Buyers of synthetic bull breeds at auctions value the phenotypic characteristics of bulls more than they do genetic characteristics, which may not reflect permanent gains in the cattle herd.

Abstract Background Despite no evidence showing benefits of hydroxychloroquine and chloroquine with or without azithromycin for COVID-19 treatment, these medications have been largely prescribed in Brazil. Objectives To assess outcomes, including in-hospital mortality, electrocardiographic abnormalities, hospital length-of-stay, admission to the intensive care unit, and need for dialysis and mechanical ventilation, in hospitalized COVID-19 patients who received chloroquine or hydroxychloroquine, and to compare outcomes between those patients and their matched controls. Methods A retrospective multicenter cohort study that included consecutive laboratory-confirmed COVID-19 patients from 37 Brazilian hospitals from March to September 2020. Propensity score was used to select matching controls by age, sex, cardiovascular comorbidities, and in-hospital use of corticosteroid. A p-value <0.05 was considered statistically significant. Results From 7,850 COVID-19 patients, 673 (8.6%) received hydroxychloroquine and 67 (0.9%) chloroquine. The median age in the study group was 60 years (46 - 71) and 59.1% were women. During hospitalization, 3.2% of patients presented side effects and 2.2% required therapy discontinuation. Electrocardiographic abnormalities were more prevalent in the chloroquine/hydroxychloroquine group (13.2% vs. 8.2%, p=0.01), and the long corrected QT interval was the main difference (3.6% vs. 0.4%, p<0.001). The median hospital length of stay was longer in the HCQ/CQ + AZT group than in controls (9.0 [5.0, 18.0] vs. 8.0 [4.0, 14.0] days). There was no statistical differences between groups in intensive care unit admission (35.1% vs. 32.0%; p=0.282), invasive mechanical ventilation support (27.0% vs. 22.3%; p=0.074) or mortality (18.9% vs. 18.0%; p=0.682). Conclusion COVID-19 patients treated with chloroquine or hydroxychloroquine had a longer hospital length of stay, when compared to matched controls. Intensive care unit admission, invasive mechanical ventilation, dialysis and in-hospital mortality were similar.

Resumo Fundamento Apesar da ausência de evidência mostrando benefícios da hidroxicloroquina e da cloroquina combinadas ou não à azitromicina no tratamento da covid-19, esses medicamentos têm sido amplamente prescritos no Brasil. Objetivos Avaliar desfechos, incluindo moralidade hospitalar, alterações eletrocardiográficas, tempo de internação, admissão na unidade de terapia intensiva, e necessidade de diálise e de ventilação mecânica em pacientes hospitalizados com covid-19 que receberam cloroquina ou hidroxicloroquina, e comparar os desfechos entre aqueles pacientes e seus controles pareados. Métodos Estudo multicêntrico retrospectivo do tipo coorte que incluiu pacientes com diagnóstico laboratorial de covid-19 de 37 hospitais no Brasil de março a setembro de 2020. Escore de propensão foi usado para selecionar controles pareados quanto a idade, sexo, comorbidades cardiovasculares, e uso de corticosteroides durante a internação. Um valor de p<0,05 foi considerado estatisticamente significativo. Resultados Dos 7850 pacientes com covid-19, 673 (8,6%) receberam hidroxicloroquina e 67 (0,9%) cloroquina. A idade mediana no grupo de estudo foi 60 (46-71) anos e 59,1% eram mulheres. Durante a internação, 3,2% dos pacientes apresentaram efeitos adversos e 2,2% necessitaram de interromper o tratamento. Alterações eletrocardiográficas foram mais prevalentes no grupo hidroxicloroquina/cloroquina (13,2% vs. 8,2%, p=0,01), e o prolongamento do intervalo QT corrigido foi a principal diferença (3,6% vs. 0,4%, p<0,001). O tempo mediano de internação hospitalar foi maior no grupo usando CQ/HCQ em relação aos controles (9,0 [5,0-18,0] vs. 8,0 [4,0-14,0] dias). Não houve diferenças estatisticamente significativas entre os grupos quanto a admissão na unidade de terapia intensiva (35,1% vs. 32,0%; p=0,282), ventilação mecânica invasiva (27,0% vs. 22,3%; p=0,074) ou mortalidade (18,9% vs. 18,0%; p=0,682). Conclusão Pacientes com covid-19 tratados com cloroquina ou hidroxicloroquina apresentaram maior tempo de internação hospitalar, em comparação aos controles. Não houve diferença em relação a admissão em unidade de terapia intensiva, necessidade de ventilação mecânica e mortalidade hospitalar.

Abstract The purpose of circular economy is to maximize resources efficiency. With the increase in consumption of raw materials, energy and waste generation, recycling is necessary for environmental and industrial reasons. Thus, the powder metallurgy, together with mechanical milling, stands as a new method for scraps recycling. This study aimed to produce UNS S31803 duplex stainless steel powders, with vanadium carbide (VC) addition as reinforcement, through mechanical milling. Different uniaxial compaction pressures (700, 800 and 900 MPa) were used, as well as sintering temperatures (1200, 1240 and 1280 °C) and times (1, 1.5 and 2 hours), in order to determine the best conditions. Particle size analysis, scanning electron microscopy and x-ray diffraction were used to characterize the powders. It was observed that the use of VC increased the comminution during the milling process, being obtained an average particle size of 42 μm. The highest density obtained was of 82% and hardness of 72%, in comparison with the steel from the manufacturing process. According to the analysis, it was verified that this method is viable, becoming an alternative route to reuse UNS S31803 duplex stainless steel scraps.
