ABSTRACT State parks are integral protection units created to protect ecosystems. However, anthropic activities may have been previously performed before their creation, forming transitional areas. Studies that evaluate the modifications of edaphic properties in these environments are scarce. The aim of this study was to evaluate the changes in soil properties and litter stock in areas of eucalyptus-forest ecotones. Litter stock (Stocklitter) and total soil organic carbon content and stock (TOCsoil), weighted mean diameter (MWD), origin of aggregates (biogenic or physicogenic) and respective content of total organic carbon (TOCBio and TOCPhy), total organic carbon (TOCAG), soil organic matter chemical fractions [fulvic acid (FAC), humic (HAC), and humin (HUMC)], and particulate, mineral-associated, free light and intra-aggregate light (POC, MAOC, FLFC, and ILFC) soil organic matter, fertility, and glomalin-related soil protein (GRSP) fractions were evaluated in aggregates (layer 0.00-0.10 m) in areas of eucalyptus-forest ecotone (Eco), preserved forest fragment (For), and eucalyptus plantation (Euc), in Nova Baden State Park, Lambari–MG. In the Euc and Eco areas, the highest Stocklitter content was found. Higher values of TOCsoil, TOCAG, GRSP, and MWD were observed in the Euc area. In the biogenic aggregates, the highest content of TOCBio, HAC, HUMC, POC, MAOC, FLFC, and ILFC was determined in detriment of the physicogenic ones. The dynamics of edaphic properties in the Eco area showed greater similarity with the For area than in the Euc area. In general, all vegetation covers contribute to the maintenance of soil quality.

ABSTRACT The erect prickly pear (Opuntia stricta Haw) is an important alternative used to feed ruminants during prolonged periods of drought. The objective of this research was to evaluate the effect of different types and concentrations of cytokinins on the morphophysiological aspects of in vitro multiplication of O. stricta. Segments of O. stricta were grown in liquid and semisolid Murashige and Skoog (MS) medium supplemented with 2.22 or 1.11 µM l-1 of 6-benzylaminopurine (BAP) and 1.11 µM l-1 meta-Topolin (mT). The experiment was conducted in a growth room at 25±2 °C over a period of 45 days. It were evaluated multiplication rate, shoot formation index, rooting and callus formation, fresh biomass, height, activity of antioxidant enzymes, and content of hydrogen peroxide and malondialdehyde. The experiment was carry out in a completely randomized design with six treatments and twelve replicates. The results showed that the consistency of the medium had influence on the shoots development and roots emission. The increase in BAP concentrations resulted in a reduction in the length and fresh biomass of the shoots and in the root system. The enzymatic activity and oxidative stress were inducted with the use of 6-benzylaminopurine. The micropropagation of O. stricta was improved with the use of mT, verified through shoot with better morphophysiological quality for acclimatization, with longer shoot length, rooting and reduction in the occurrence of hyperhydricity, a morphophysiological disorder that leads to large losses in micropropagation of this specie.

RESUMEN El nopal erecto (Opuntia stricta Haw) es una alternativa importante que se utiliza para alimentar a los rumiantes durante períodos prolongados de sequía. El objetivo de esta investigación fue evaluar el efecto de diferentes tipos y concentraciones de citoquininas en los aspectos morfofisiológicos de la multiplicación in vitro de O. stricta. Se cultivaron segmentos de O. stricta en medio de cultivo líquido y semisólido de Murashige y Skoog (MS) con 2.22 o 1.11 µM l-1 de 6-bencilaminopurina (BAP) y 1.11 µM l-1 de meta-Topolina (mT). El experimento se realizó en una sala de crecimiento a 25 ± 2 °C durante un período de 45 días. Se evaluaron la tasa de multiplicación, el índice de formación de brotes, la formación de raíces y callos, la biomasa fresca, la altura, la actividad de las enzimas antioxidantes y el contenido de peróxido de hidrógeno y malondialdehído. El experimento se realizó con un diseño completamente al azar con seis tratamientos y doce repeticiones. Los resultados mostraron que la consistencia del medio de cultivo influyó en el desarrollo de brotes y en la emisión de raíces. El aumento en las concentraciones de BAP resultó en una reducción en la longitud y la biomasa fresca de los brotes y en el sistema radicular. La actividad enzimática y el estrés oxidativo se indujeron con el uso de 6-bencilaminopurina. La micropropagación de O. stricta se mejoró con el uso de mT, verificado a través de brotes con mejor calidad morfofisiológica para la aclimatización con mayor longitud de brotes, enraizamiento y reducción en la aparición de hiperhidricidad, un trastorno morfofisiológico que conduce a grandes pérdidas de micropropagación de esta especie.

ABSTRACT Introduction: Breast cancer is the second most common type of cancer among women in Brazil. An estimated 59,700 new cases of breast cancer were reported in the 2018-2019 biennium. Breast reconstruction is a safe procedure, and various surgical procedures have been described, including conservative techniques and use of neighborhood flaps, alloplastic materials, and pedicled and microsurgical myocutaneous flaps. The objective of this study was to analyze cases of breast reconstruction after mastectomy for breast cancer performed over a period of 16 years. Methods: We reviewed the medical records of patients who underwent breast reconstruction after mastectomy for breast cancer between January 2002 and December 2017. Results: Within the study period, 586 patients underwent breast reconstruction. Breast reconstruction was performed with a transverse rectus abdominis myocutaneous muscle (TRAM) flap in 160 patients, with conservative techniques in 107 patients, with a latissimus dorsi myocutaneous flap (LDMF) in 156 patients, with prostheses in 113 patients, and secondarily in 50 patients. Before October 2007, the proportion of patients who underwent bilateral surgeries with a TRAM flap and LDMF was 30%, and since then, the percentage has increased to 83.3%. One or more types of complications occurred in 203 patients (34.64%) who underwent surgery, with a total of 335 complications . Most outpatient complications did not require surgical reassessment. Conclusion: The incidence of bilateral surgery increased, which is attributed to the increase in the number of prophylactic mastectomies in the contralateral breast and in the number of reconstructions using a LDMF compared with that using a TRAM flap. A significant increase in the number of reconstructions with silicone implants was also observed.

RESUMO Introdução: Câncer de mama é o segundo tipo mais comum de câncer entre mulheres no Brasil. Estimam-se 59.700 casos novos de câncer de mama para o biênio 2018-2019. Reconstrução mamária é um procedimento seguro e vários procedimentos cirúrgicos são descritos para sua realização: técnicas conservadoras, retalhos de vizinhança, materiais aloplásticos, retalhos miocutâneos pediculados e microcirúrgicos. O objetivo deste estudo foi analisar os casos de reconstrução mamária pós-mastectomia por câncer de mama, realizados em um período de 16 anos. Métodos: Foi realizada revisão de prontuários de pacientes submetidas à reconstrução mamária pós-mastectomia por câncer de mama, no período de janeiro de 2002 a dezembro de 2017. Resultados: No período analisado, 586 pacientes foram submetidas à reconstrução mamária. Em 160 pacientes a reconstrução mamária foi realizada com retalho miocutâneo do músculo retoabdominal (TRAM), 107 com técnicas conservadoras, 156 com retalho miocutâneo do músculo grande dorsal (RGD), 113 com próteses e 50 secundárias. Previamente a outubro de 2007, a porcentagem de pacientes submetidas a cirurgias bilaterais, somando-se TRAM e RGD, era de 30%, e a partir desse período a porcentagem passou para 83,3%. Houve algum tipo de complicação ou intercorrência em 203 (34,64%) pacientes operadas, totalizando de 335 complicações. Grande maioria apresentou intercorrências tratadas ambulatorialmente sem necessidade de reabordagem cirúrgica. Conclusão: Houve aumento da incidência de cirurgias bilaterais, fato atribuído ao aumento das mastectomias profiláticas na mama contralateral e aumento do número de reconstruções utilizando RGD em comparação com o TRAM, bem como o aumento significativo das reconstruções com implante de silicone.

Resumen: En | Texto: En | PDF: En

ABSTRACT Aiming to minimize the environmental pollution and reducing the production costs of the composite materials, the use of plant fibers improves their physical and mechanical properties. On the other hand, fibers have high water absorption, which may increase their volume and weaken the fiber/matrix interaction, affecting the mechanical features of the composites. Concerned with this problem, this research had the objective of making 3 and 10 millimeter-thick specimens, containing 23% (m/m) of Caroa fibers and 73% (m/m) of unsaturated polyester. Samples were withdrawn after 0, 2, 4, 7, 12 and 21 days of exposure at room temperature water (ASTM D570 − 98). Then, the test of tensile (ASTM D 3039), flexural (ASTM D 790-03) and impact (ASTM D 256) was realized and the mechanical properties were analyzed. The samples subjected to humidity had their fibers degraded and presented loss of mechanical properties, more significant in composite with 3 mm. For example, the reduction of the strengths tensile, after 21 days of test were 80% for composites with 3 mm and 60% for composites with 10 mm. Studies like this are important for long-term applications of such composites in humid environments.

RESUMO O crescimento dos centros urbanos no país demanda cada vez mais a adoção de novas opções de mobilidade, e diante desta necessidade foi elaborado e iniciado um projeto que visa construir um corredor fluvial de passageiros em uma parte do rio Capibaribe na cidade do Recife-PE. Para a implantação de um canal de navegação são necessárias dragagens de aprofundamento para definir uma geometria do leito do rio compatível com as necessidades das embarcações que irão percorrer o canal. O acompanhamento das dragagens se faz com os constantes levantamentos batimétricos de onde são retiradas as informações dos volumes de sedimentos dragados, tendo como objetivo também verificar o comportamento temporal dos processos de deposição e erosão. Nesse contexto, o trabalho teve como objetivo avaliar a geometria do leito do rio Capibaribe após as dragagens de aprofundamento, utilizando dados de levantamentos batimétricos em períodos distintos para confeccionar perfis longitudinais e transversais, e criar modelos digitais de profundidade para extração de informações sobre a deposição/agradação ou erosão/remoção de sedimentos e os seus respectivos volumes. O perfil primitivo do rio Capibaribe apresentou suave declividade e heterogeneidade nas formas do fundo, principalmente após o quilômetro cinco, com tendências de deposição/agradação a jusante da região de confluência com tributário advindo do açude de Apipucos e a montante dos trechos sinuosos, nos locais de alargamento da seção transversal, e a montante da bifurcação situada no quilometro nove. Os cenários após as dragagens de aprofundamento indicam locais com predominância dos processos erosivos e em outros, processos de sedimentação. Foram comparados os perfis longitudinais e transversais de duas áreas situadas no canal de navegação oeste, uma com 350 metros e outra com 1000 metros, onde se verificou que na área 1 a erosão/remoção de sedimentos superou a sedimentação/agradação, indicando a ocorrência de dragagens no intervalo entre os dois levantamentos associado aos processos naturais. Na área de estudo 2 o processo de sedimentação/agradação superou o de remoção/erosão, com um volume equivalente a uma camada de 1 cm de espessura. A agradação ocorreu de forma homogênea no canal de navegação, enquanto que a erosão localizou-se nas margens, mais intensamente na margem direita do rio.

ABSTRACT The growth of urban centers in the country are increasingly dependent on the adoption of new mobility options, and before this need was developed and initiated a project to build a river corridor passenger in a part of the Capibaribe River in the city of Recife-PE. For the implementation of a navigation channel deepening are needed dredging to define a geometry of the bed of the river compatible with the needs of ships that will traverse the channel. The monitoring of dredging is done with the constant bathymetric surveys where the information volumes of dredged sediments are removed, aiming to also check the temporal behavior of deposition and erosion processes. In this context, the work aimed to evaluate the geometry of the Capibaribe river bed after the deepening dredging, using data from bathymetric surveys at different times for making longitudinal and transverse profiles, and create digital models of depth to extract information about the deposition/aggradation or erosion/removing sediments and their respective volumes. Early Profile Capibaribe river showed mild slope and heterogeneity in the bottom of the form, especially after kilometer five, with trends of deposition/aggradation downstream of the confluence region with tax arising from the weir Apipucos and upstream of the winding sections in local enlargement of the cross section, and the amount of the fork located at kilometer nine. The scenarios after the dredging to deepen indicate places with predominance of erosion and other sedimentation processes. They compared the longitudinal and transverse profiles of two areas located in western shipping channel, one with 350 meters and over 1000 meters, where it was found that the area 1 to erosion/sediment removal exceeded sedimentation/aggradation, indicating the occurrence of dredging the interval between the two surveys linked to the natural processes. In the study area 2 the sedimentation/aggradation exceeded the removal/erosion, with a volume equivalent to 1 cm thickness. The aggradation occur homogeneously in the navigation channel, while erosion was located on the banks, more intensely on the right bank of the river.

RESULTADOS: Todos os itens foram considerados pertinentes ao construto e foi atingida boa equivalência semântica da versão. A análise fatorial exploratória demonstrou carga fatorial adequada de todos os itens e boa consistência interna, com a de Cronbach de 0,81. Foi evidenciada diferença significativa entre o escore final do CDDUX de crianças e seus pais. Não houve diferença do escore final do questionário em relação ao sexo ou à idade. CONCLUSÃO: A tradução e adaptação seguiram adequadamente as etapas propostas, com a equivalência sendo atingida de maneira satisfatória. O instrumento traduzido mostrou-se válido para avaliação da QV de crianças e adolescentes com DC.

ABSTRACT OBJECTIVE: To translate, cross-culturally adapt, and validate a specific questionnaire for the evaluation of celiac children and adolescents, the celiac disease DUX (CDDUX). METHODS: The steps suggested by Reichenheim and Moraes (2007) were followed to obtain conceptual, item, semantic, operational, and measurement equivalences. Four pediatric gastroenterologists; a researcher with tool validation background; three English teachers; and 33 celiac patients, aged 8-18 years, and their caregivers participated in the study. The scores of celiac patients and those obtained from their caregivers were compared. Among the patients, the scores were compared in relation to gender and age. RESULTS: All items were considered relevant to the construct and good semantic equivalence of the version was acquired. During measurement equivalence, the exploratory factor analysis showed appropriate weight of all items and good internal consistency, with Cronbach's a of 0.81. Significant difference was found among the final scores of children and their caregivers. There was no difference among the final scores in relation to gender or age. CONCLUSION: The questionnaire was translated and adapted according to all the proposed steps, with all equivalences adequately met. It is a valid tool to access the QoL of celiac children and adolescents in the translated language.

ABSTRACT Introduction: A mastectomy is the standard treatment for all types of breast cancer (CA). This disease, with the exception of non-melanoma skin cancers, ranks first cancers that affect women. Many are the possibilities for full mastectomy reconstruction, involving autologous flaps and implant placement. Advances in the use of these techniques have been refined over the years in order to provide excellent results.The aim of this study is to describe the technique of breast reconstruction with the fat dermal inferior pedicle flap associated with pectoral and analysis of postoperative results. Methods: Retrospective analysis of medical records of patients operated for treatment of breast cancer in the period 2008-2013, in the private practice of the author and all patients had tumors located in the upper quadrants were selected was performed. Results: Over this period, 210 patients underwent breast reconstruction. Of these, 17 (8.09%) underwent breast reconstruction by the proposed technique. Over this period, 210 patients underwent breast reconstruction. Of these, 17 (8.09%) underwent breast reconstruction by the proposed technique. Regarding postoperative complications, there was 1 case of skin necrosis and 1 case of asymmetry. Conclusions: Apart from technically simple and acceptable cosmetic results, the proposed flap does not result in donor site morbidity, prolonged recovery, muscle weakness with the advantage that, in most cases, be accomplished in a single operation.

RESUMO Introdução: A mastectomia é o tratamento padrão para todos os tipos de câncer (CA) de mama. Essa doença, com exceção dos cânceres de pele não melanoma, ocupa o primeiro lugar dos cânceres que acometem as mulheres. Muitas são as possibilidades de reconstrução para mastectomia total, envolvendo retalhos autólogos e colocação de implantes. Os avanços na utilização dessas técnicas têm sido aprimorado ao longo dos anos de forma a proporcionar excelentes resultados. O objetivo deste trabalho é a descrição da técnica de reconstrução mamária com retalho dermogorduroso de pedículo inferior associado ao músculo peitoral e análise dos resultados. Métodos: Foi realizada análise retrospectiva de prontuários das pacientes operadas para tratamento de câncer de mama, no período de 2008 a 2013, na clínica privada do autor. Foram selecionadas todas as pacientes que apresentavam tumores localizados nos quadrantes superiores. Resultados: No período analisado, 210 pacientes foram submetidas à reconstrução mamária. Destas, 17 (8,09 %) foram submetidas à reconstrução de mama pela técnica proposta. Com relação às complicações pós-operatórias, observou-se 1 caso de necrose da pele e 1 caso de assimetria. Conclusão: Além de tecnicamente simples e com resultados estéticos aceitáveis, o retalho proposto não acarreta em morbidade de sítio doador, recuperação prolongada, fraqueza muscular com a vantagem de, na maioria das vezes, ser realizado em um único tempo cirúrgico.

ABSTRACT Introduction: The transverse rectus abdominis muscle (TRAM) flap, described by Drever in 1977, was subsequently modified and since then, has rapidly become an important alternative for breast reconstructions. However, bulges and abdominal hernias in the donor area are some of the complications arising from the TRAM flap. This study proposes an alternative technique for the repair of the abdominal defect that minimizes complications and provides better results. Method: The retrospective included 120 women who underwent breast reconstruction with TRAM with placement of an abdominal mesh between May 2003 and November 2012, with follow-up of at least six months. Patients were divided into two groups: Group 1 (53 cases) underwent reconstruction with polypropylene mesh positioned between the aponeurotic layers of the external and internal oblique muscles and Group 2 (67 cases) underwent closure of the arcuate Douglas’ line and the remaining lower aponeurosis of the rectus abdominis muscle and reinforcement with mesh. Results: The patients were evaluated by the same surgeon, according to the same criteria. The rate of bulging was 18.9% in group 1 and 3% in group 2, a statistically significant difference. Bulges and hernias in the hypogastrium varied from 20% to 44% and 12.5% to 20% respectively, when closed primarily. When synthetic mesh was used, these percentages decreased to 1.5% to 6%. The technical improvement and comparison of results aims to minimize such complications. Conclusion: The technique described is advantageous in that, it significantly reduced the occurrence of the most common complication, and increased the aesthetic and functional satisfaction of the patients.

RESUMO Introdução: O retalho do músculo reto abdominal, descrito por Drever em 1977, foi posteriormente modificado e, desde então, se tornou rapidamente uma importante alternativa para reconstrução da mama. Dentre as complicações do TRAM, citam-se os abaulamentos e hérnias abdominais na área doadora. Este estudo vem propor uma técnica alternativa de reparo do defeito abdominal, com o objetivo de minimizar tais inconvenientes e proporcionar melhores resultados. Método: O estudo é de caráter retrospectivo, totalizando 120 mulheres submetidas à reconstrução mamária com TRAM com colocação de tela abdominal, e seguimento mínimo de seis meses, entre Maio de 2003 e Novembro de 2012. As pacientes foram divididas em dois grupos: Grupo 1 (53 casos) reconstruídos com tela de polipropileno posicionada entre os folhetos aponeuróticos dos músculos oblíquo externo e interno, e Grupo 2 (67 casos) realizado fechamento da linha arqueada de Douglas e o remanescente inferior da aponeurose do músculo reto abdominal e reforço com tela. Resultados: As pacientes foram avaliadas pelo mesmo cirurgião, obedecendo aos mesmos critérios. Os resultados obtidos foram 18,9% de abaulamentos no grupo 1 e 3% no grupo 2, estatisticamente significativo. Abaulamentos e hérnias no hipogástrio variam de 20% a 44% e 12,5% a 20% respectivamente, quando fechados primariamente. Quando associado a aplicações de telas sintéticas, esses percentuais diminuem para 1,5% a 6%. O aprimoramento técnico e a comparação de resultados têm a finalidade de minimizar tais complicações. Conclusão: A técnica descrita mostra-se vantajosa, pois permitiu significativa diminuição da complicação mais comum, permitindo satisfação estética e funcional das pacientes.

PURPOSE: A great number of small renal lesions have now been detected. Nowadays, partial nephrectomy has more frequently been adopted for surgical treatment of earlier stage disease. Previous studies have associated patient, institutional, and health care system factors with surgery type. The aim of this study was to compare the diagnosis and treatment of renal cell carcinoma (RCC) according to hospital type, public versus private, in our country. MATERIALS AND METHODS: We retrospectively evaluated 183 patients with RCC who underwent radical nephrectomy or nephron-sparing surgery between 2003 and 2007 in two hospitals, one private and one public. Patient demographic, clinical, surgery, and pathologic characteristics were analyzed. RESULTS: The radical nephrectomy rate was higher at the public hospital than at the private hospital (75% vs. 57%, p = 0.008). Overall, patients at the public hospital presented larger tumors than did the patients who were cared for privately. Furthermore, small renal masses were significantly more prevalent in private care (57.8% vs. 28.3%). Patients at the public hospital showed a higher incidence of capsular invasion (p = 0.008), perirenal fat invasion (p < 0.01), lymph node involvement (p < 0.001), and a lower incidence of initial tumors. pT1 tumors were reported in 41% of patients at the public hospital and in 72% at the private hospital (p < 0.001). CONCLUSION: Patients with RCC cared for at our public referral hospital showed a more advanced stage than RCC treated at the private institution.

INTRODUCTION: Chronic testicular pain remains an important challenge for urologists. Currently, the treatment plan is primarily empirical, with the first approach consisting of clinical measures. However, some patients remain in pain despite a conservative treatment protocol and, for them, it is possible to perform a surgical procedure that involves severing the scrotal and spermatic branches of the genitofemoral and ilioinguinal nerve fibers.
