Abstract This is an original article that addresses the healthcare workforce (HW) in Brazil, as well as comorbidities and mental health changes during the COVID-19 pandemic. This study was conducted by the Oswaldo Cruz Foundation and collected data through an online questionnaires from a total of 36,612 participants, health professionals (HP, with higher education level), and invisible healthcare workers (IHW, with a technical mid-level education). The overall prevalence of comorbidities in Brazil was 26.1% and 23.9%; the highest was arterial hypertension (27.4% and 31.9%), followed by obesity (18.4% and 15.1%), chronic respiratory diseases (15.7% and 12.9%), diabetes mellitus (10.3% and 10.4%), and depression/anxiety (9.1% and 11.7%), in the HW and IHW, respectively. The region with the highest frequency was the southeast, where the largest contingent of workers is located. The HW, affected with a high burden of non-communicable chronic diseases and exposed to SARS-CoV-2, proved to be vulnerable to illness and death. Mental symptoms and intense psychological suffering have been reported. These results allow us to estimate the impacts upon physical and mental health, as well as upon living and working conditions of the HW. The health and life of workers, leading role in facing health challenges of the pandemic, are a high priority in public policies.

ABSTRACT. This study aimed to evaluate the effects of different levels of dietary fiber on the performance and egg quality of laying hens at pre-laying and laying peak periods. The experimental period was divided into three periods: pre-laying (16 to 19 weeks of age), the start of laying (20 to 22 weeks of age) and laying peak (23 to 28 weeks of age). The experimental design was completely randomized with treatments constituted by five levels of fiber (2.00, 2.50, 3.00, 3.50, and 4.00%) in the diets, with five replicates (pens) of six birds each, totalling 180 hens. Performance and egg quality results were evaluated by polynomial regression at 5%. Fiber levels were not influenced (p >0.05) the first laying of the hens. However, levels above 2.50% of fiber provided worst (p <0.05) performance results, regardless of the period evaluated. Shortly after the start of laying, higher levels of fiber also caused a linear reduction (p <0.05) on egg weight and percentages of yolk and albumen, and an increase (p <0.05) on eggshells. Higher fiber levels caused a linear reduction (p <0.05) in the quality of the eggs, regardless of the period evaluated. It was concluded that the fiber levels did not influence the start period of the laying. Both pre-laying and start of the laying, levels above 2.5% of fiber caused a gradual worsening in performance. From the start of laying up to laying peak, levels above 2.5% of fiber also caused a gradual worsening in egg quality.

ABSTRACT The investigation aims to analyze the technical viability of addition the waste from the filter-press from the mineral coal treatment process (TFP) and bottom ash from a thermoelectric (CP), in ceramic paste on the laboratory scale. Physical-chemical characterization and waste classification tests were carried out. Subsequently, ten formulations were developed through the mixture design (DoE), incorporating these residues into a standard clay ceramic paste (STD). The samples were formed by extrusion without vacuum and subjected to heat treatment in an oven and fired in a muffle at 900 °C. The evaluated technological properties were: shrinkage of drying and firing, water absorption and mechanical resistance and, finally, efflorescence tests and phytotoxicological analysis were performed. The results of solid waste classification, indicated these as not being dangerous (Class II-B - inert). The technical analysis of the samples show that compared to the clay ceramic standard formulation (STD), the other mixtures obtained results within the technical parameters, which can later be carried out in an industrial scale test. Although the mechanical tests with waste incorporation were below the standard formulation (STD), a test on an industrial scale is not discarded. In the efflorescence test, it was observed that there was no presence of soluble salts. And finally, in the phyto-toxicological test, with Allium cepa L. of a formulation with aggregation of all raw materials, it presented a result marginally similar to the standard, proving itself capable of reproduction on an industrial scale.

RESUMO A investigação teve por objetivo analisar a viabilidade técnica de incorporação do resíduo proveniente do filtro prensa do processo de beneficiamento do carvão mineral (TFP) e de cinzas pesadas (CP) advindos de uma termoelétrica, em massa cerâmica na escala laboratorial. Foram realizados ensaios de caracterização físico-química e de classificação dos resíduos. Posteriormente foram desenvolvidas dez formulações através de planejamento experimental por delineamento de misturas simplex centroide, incorporando esses resíduos a uma massa padrão de cerâmica vermelha. Os corpos-de-prova foram conformados por extrusão sem vácuo e submetidos a tratamento térmico em estufa e queima em forno mufla a 900 °C. As propriedades tecnológicas avaliadas foram: retração térmica linear de secagem e de queima, absorção de água e resistência mecânica à compressão e por fim, foram realizados testes de eflorescência e análise fitotoxicológica. Os resultados de classificação dos resíduos, indicaram esses como não sendo perigoso – Classe II-B – inerte. Os testes físicos dos corpos-de-prova mostram que comparados a formulação base de cerâmica vermelha (STD), as demais formulações obtiveram resultados dentro dos parâmetros técnicos, que podem ser posteriormente realizados em um ensaio de escala industrial. Embora os ensaios mecânicos das provas com incorporação de resíduo ficaram abaixo da formulação base (STD), não se descarta uma prova em escala similar a industrial. No ensaio de eflorescência, observou-se que não houve presença de sais solúveis. E por fim, no ensaio fitotoxicológico, com Allium cepa L. de uma formulação com agregação de todas matérias-primas juntas, apresentou um resultado próximos ao padrão, se mostrando apto a reprodução em escala industrial.

Abstract A key issue in evaluating agricultural factor productivity in Brazil is the existing wide variation in farm sizes. In this study, we follow a quantile regression approach and use bootstrapping techniques to estimate a flexible production function to show that factor productivity does vary across and within land size groups. This happens not only because farms of different sizes use different input proportions but rather due to the existence of inter and intragroup farm-specific effects. Our results suggest that usual average measures of factor productivity of previous studies may then be poorly describing the Brazilian agriculture, likely leading to confounding conclusions. study groups farmspecific specific effects agriculture conclusions

Abstract Microalloyed steels have a maximum of 2% in alloying elements and are used in the automotive and petrochemical industries. The microstructure and mechanical properties of these steels depend on chemical composition, processing and addition of molybdenum, niobium, titanium and vanadium. To evaluate the molybdenum effect in microstructure and mechanical properties, two microalloyed steels, with similar levels of niobium, titanium and vanadium, were prepared and forged. The steels have 0.056 and 0.160 percent by weight of molybdenum. The bars were homogenized, quenched and tempered. The specimens were machined for tensile and impact tests, hardness and microstructural analyzes by confocal and scanning electron microscopy. The ThermoCalc software was used to evaluate the carbides characteristics. The results show that steel with 0.160% Mo presents greater amount of bainite and austenite retained. It’s possible that formation of carbides by the secondary hardening mechanism increase in mechanical strength and a reduction in toughness.

ABSTRACT. Phosphorus (P) is one of the most important elements used in fertilizing soils in tropical regions due to the low efficiency of phosphate fertilization. This work aimed to fractionate inorganic P (Pi) in tropical soils of different mineralogical compositions and to relate these fractions with their respective phosphate buffer capacity (PBC) indicators. The soils were characterized physically, chemically and mineralogically. Additionally, we evaluated the P concentration that remained in solution of soil after equilibrium was met; this was termed P remaining (P-rem). In general, the Pi fractions of soils did not correlate with the PBC indicators. The P-H2O fraction showed a negative correlation with the P-Al fraction. Ferric minerals did not influence P fixation. P-rem showed a strong correlation with the maximum P adsorption capacity, adsorption energy, and the amorphous and crystalline forms of Fe. The minerals of aluminum contributed the most to P fixation. P-rem was the best estimator of PBC. The soils with high, moderate and low rates of P fixation showed high amounts of the fractions P-Al, P-Ca, and P-Fe, respectively. The results showed that P fixation was influenced by the fractions of P in the soil, suggesting that the efficiency of phosphate fertilizers in tropical soils depends on the mineralogy of the clay fraction within those soils.

Resumo O conceito de recovery no campo da saúde mental, oriundo do movimento de pacientes e familiares nos países anglo-saxões, tornou-se relevante para a compreensão de práticas de cuidado, valorizando aquelas que incorporem o protagonismo dos usuários e uma dimensão crítica dos métodos de tratamento. Tendo como objetivo investigar as diferentes perspectivas nas quais o conceito vem sendo compreendido e experimentado no contexto da Reforma Psiquiátrica Brasileira, realizou-se uma revisão integrativa da literatura publicada no país sobre o recovery, tomando como critério de inclusão textos que relatam ou analisam experiências concretas de cuidado e que se definam como sendo ‘baseadas no recovery’. Após ampla busca, foram analisados 32 trabalhos, entre artigos, dissertações e teses. O termo recovery aparece na bibliografia brasileira de saúde mental a partir de 2011, e os trabalhos concentram-se notavelmente nos estados de São Paulo e Rio de Janeiro, ligados a instituições de ensino superior e pesquisa. Grande parte da produção não incorpora elementos-chave do conceito estudado, como o protagonismo de usuários, além de por vezes tomar recovery como sinônimo de reabilitação psicossocial. Apesar do avanço e da consolidação do campo da atenção psicossocial no país, a dimensão do protagonismo de usuários ainda é incipiente na experiência brasileira.

Abstract The concept of recovery in the field of mental health, originating from the movement of patients and families in Anglo-Saxon countries, has become relevant for the understanding of care practices, valuing those that incorporate the protagonism of users and a critical dimension of treatment methods. Aiming to investigate the different perspectives in which the concept has been understood and experienced in the context of the Brazilian Psychiatric Reform, an integrative review of the published literature in the country regarding recovery was carried out, taking as inclusion criteria texts that report or analyze concrete experiences of care and define themselves as ‘recovery based’. After an extensive search, 32 works were analyzed, including articles, dissertations and theses. The term recovery appears in the Brazilian mental health bibliography from 2011 onwards, and the works are notably concentrated in the states of São Paulo and Rio de Janeiro, linked to higher education and research institutions. Much of the production does not incorporate key elements of the concept studied, such as the role of users, in addition to sometimes taking recovery as a synonym for psychosocial rehabilitation. Despite the advancement and consolidation of the field of psychosocial care in the country, the dimension of the role of users is still incipient in the Brazilian experience.

Resumen El concepto de recovery en el campo de la salud mental, originario del movimiento de pacientes y familiares en los países anglosajones, se volvió relevante para la comprensión de las prácticas de cuidado, valorando aquellas que incorporan el protagonismo de los usuarios y una dimensión crítica de los métodos de tratamiento. Con el objetivo de investigar las diferentes perspectivas en que el concepto ha sido entendido y vivido en el contexto de la Reforma Psiquiátrica Brasileña, se realizó una revisión integradora de la literatura publicada en el país sobre el recovery, tomando como criterio de inclusión textos que informen o analicen experiencias concretas de cuidado y que se definen a sí mismas como ‘basadas en el recovery’. Luego de una extensa búsqueda, se analizaron 32 trabajos, entre artículos, disertaciones y tesis. El término recovery aparece en la bibliografía brasileña de salud mental a partir de 2011, y los trabajos se concentran notablemente en los estados de São Paulo y Rio de Janeiro, vinculados a instituciones de enseñanza superior y de investigación. Gran parte de la producción no incorpora elementos clave del concepto estudiado, como el protagonismo de los usuarios, además de tomar, en ocasiones, recovery como sinónimo de rehabilitación psicosocial. A pesar del avance y consolidación del campo de la atención psicosocial en el país, la dimensión del protagonismo de los usuarios aún es incipiente en la experiencia brasileña.

RESUMO Introdução: O uso de impressão em 3-D na área da saúde tem contribuído para o desenvolvimento de instrumentos e próteses. A impressão 3-D tem sido usada para o ensino de futuros profissionais. Para se alcançar uma boa peça em 3-D, é necessário ter imagens de alta qualidade, como aquelas geradas pelo exame de Tomografia Computadorizada (TC), que mostra a anatomia sob diferentes cortes e permite uma boa reconstrução de imagem. Objetivo: Propor um protocolo para a criação de arquivos digitais a partir de imagens de tomografia computadorizada a serem impressas em 3-D e usadas como modelo de material didático oftalmológico usando software de código aberto, InVesalius®, Bender® e Repetier-Host©. Métodos: Foram utilizadas imagens em formato DICOM provenientes de dois exames de tomografia computadorizada de órbitas para a impressão tridimensional. Para manuseio das imagens, foram utilizados o InVesalius®, versão 3.1.1, para delimitar e limpar a estrutura de interesse e também para converter em formato STL. O Blender®, versão 2.80 foi usado para refinamento. A imagem em STL foi então enviada para o programa Repetier-Host, versão 2.1.3, que divide a imagem em camadas e gera as instruções para impressão da peça em ácido polilático na impressora tridimensional. Resultados: As peças anatômicas impressas reproduziram de forma satisfatória a maioria das estruturas ósseas e musculares. No entanto, houve dificuldade durante a impressão das estruturas ósseas menores, como perda de estrutura óssea pequena, que não possuíam sustentação, por serem envoltas pelo músculo. Conclusão: Apesar das dificuldades encontradas na produção dessas peças de estudo, foi possível reproduzir estruturas com fidelidade, indicando que o protocolo proposto viabiliza a impressão de imagens oriundas da tomografia computadorizada para impressão tridimensional.

ABSTRACT Introduction: The use of tridimensional (3D) printing in healthcare has contributed to the development of instruments and implants. The 3D printing has also been used for teaching future professionals. In order to have a good 3D printed piece, it is necessary to have high quality images, such as the ones from Computerized Tomography (CT scan) exam, which shows the anatomy from different cuts and allows for a good image reconstruction. Purpose: To propose a protocol for creating digital files from computerized tomography images to be printed in 3D and used as didactic material in the ophthalmology field, using open-source software, InVesalius®, Blender® and Repetier-Host©. Methods: Two orbit CT scan exam images in the DICOM format were used to create the virtual file to be printed in 3D. To edit the images, the software InVesalius® (Version 3.1.1) was used to delimit and clean the structure of interest, and also to convert to STL format. The software Blender® (Version 2.80) was used to refine the image. The STL image was then sent to the Repetier-Host© (Version 2.1.3) software, which splits the image in layers and generates the instructions to print the piece in the 3D printer using the polymer polylactic acid (PLA). Results: The printed anatomical pieces printed reproduced most structures, both bone and soft structures, satisfactorily. However, there were some problems during printing, such as the loss of small bone structures, that are naturally surrounded by muscles due to the lack of support. Conclusion: Despite the difficulties faced during the production of the pieces, it was also possible to reproduce the anatomical structures adequately, which indicates that this protocol of 3D printing from medical images is viable.

RESUMO Diversas ações humanas têm causado degradação de solos e a revegetação dessas áreas é uma alternativa de recuperação. Contudo, em solos afetados por sais, é fundamental escolher espécies adequadas para a extração de sais do solo. Neste estudo o objetivo foi avaliar o desenvolvimento e a resposta de espécies arbóreo-arbustivas cultivadas em solo degradado por sais, estabelecidas isoladamente ou associadas à espécie fitoextratora de sais, por meio da produção de biomassa e extração de elementos pelas plantas. Um experimento de campo foi instalado em Serra Talhada-PE com oito tratamentos: 1) Atriplex nummularia Lindl., 2) Mimosa caesalpiniifolia Benth, 3) Leucaena leucocephala (Lam.) de Wit, 4) Azadirachta indica A. Juss, 5) A. nummularia + M. caesalpiniifolia, 6) A. nummularia + L. leucocephala e 7) A. nummularia + A. indica; em blocos casualizados com quatro repetições. Após 30 meses de cultivo, as plantas foram coletadas e pesadas, analisando-se teores de Na, K, Ca, Mg, Cl, P e N. Plantas de A. indica produziram mais biomassa total (10,75 kg planta-1), cerca de 15 vezes mais que M. caesalpiniifolia, ambas em cultivo associado com A. nummularia. Plantas de A. nummularia extraíram mais Na e Cl na matéria seca, com máximo de 124,70 e 166,79 g planta-1, respectivamente. A mais alta produção de biomassa vegetal (23,55 t ha-1) e extração total de elementos (1438,51 kg ha-1) foi no cultivo associado de A. nummularia e A. indica. O cultivo associado não diminuiu o potencial fitoextrator de A. nummularia, e pode ser utilizado em áreas sob recuperação.

ABSTRACT Anthropogenic actions have caused soil degradation and revegetation is a way to recover degraded soils. However, salt-affected soils require the use of suitable species to extract salts from the soil. This study investigated the growth of shrub and tree species in a soil degraded by salts, alone or associated with a phytoextraction salt species, evaluating plant biomass yield and extraction of elements by plants. A field experiment was assembled with eight treatments: 1) Atriplex nummularia Lindl., 2) Mimosa caesalpiniifolia Benth, 3) Leucaena leucocephala (Lam.) Wit, 4) Azadirachta indica A. Juss, 5) A. nummularia + M. caesalpiniifolia, 6) A. nummularia + L. leucocephala and 7) A. nummularia + A. indica; in randomized blocks with four replications. After 30 months of cultivation, plants were collected to measure biomass and concentrations of Na, K, Ca, Mg, Cl, P, and N. A. indica plants had the highest total biomass (10.75 kg plant-1), about 15 times more than M. caesalpiniifolia, both in associated cultivation with A. nummularia. A. nummularia plants extracted more Na and Cl in the dry matter, maximum of 124.70 and 166.79 g plant-1, respectively. The highest production of plant biomass (23.55 t ha-1) and total extraction of elements (1438.51 kg ha-1) were obtained by associated cultivation of A. nummularia and A. indica. Associated cultivation did not decrease the phytoextractor potential of Na and Cl by A. nummularia plants and it can be used to regenerate degraded areas.

Summary OBJECTIVE: This study aimed to compare the publications authored by plastic surgeons with those from other specialties’ surgeons on patient-reported outcomes of oncoplastic surgery. METHODS: A review was carried out on the Medline database, emcompassing five years (2015-2020). Studies about partial breast reconstruction after conservative treatment, immediate or delayed, by any technique, which presented patient-reported outcomes, were included. RESULTS: We found 292 articles, from which 142 met the eligibility criteria. Publications were stratified into groups 1 (plastic surgeons) and 2 (other surgical specialties), and also into groups A (only plastic surgeons), B (only other specialties) and C (both), and compared statistically. Most publications (60.6%) were attributed to specialties other than plastic surgery. Nineteen percent had only plastic surgeons as authors, 50% only other specialties’ surgeons, and 31% had both. There was no difference between groups regarding the impact factor of the journals in any of the stratifications, and the majority was published in journals with impact factor ≤2. CONCLUSION: In the last years, surgeons from specialties other than plastic surgery published more about the results of the oncoplastic surgery reported by the patients. There was no statistical difference between the groups regarding the impact factor of the journals.

ABSTRACT Introduction: Although treatment of head and neck cancer has evolved in recent years, it is still a challenge to preserve and restore facial symmetry afterward; this fact significantly compromises the quality of life of patients. In reconstructive surgery, autologous fat grafting has been used to treat volume and contour defects. The objective is to review the effects of fat grafting in patients with radiodermatitis due to head and neck cancer radiotherapy treatment. Methods: Literature review in PubMed and SciELO databases, looking for studies published in the last 20 years in Portuguese, English, or Spanish. The descriptors “adipose tissue”, “transplantation”, “neoplasms”, “head and neck neoplasms” and “radiotherapy” and the non-descriptive terms “fat grafting”, “fat transplantation” and “fat graft” were used. Results: Of 212 articles found, only seven complied with the eligibility criteria. Conclusion: The review suggests that fat grafting in head and neck cancer reconstruction is a safe treatment and optimizes aesthetic and functional results. Prospective studies are lacking for a better definition of techniques and results.
