ABSTRACT Differentiated thyroid carcinoma (DTC) accounts for most cases of thyroid cancer, and the heterogeneity of DTC requires that management decisions be taken by a multidisciplinary team involving endocrinologists, head and neck surgeons, nuclear medicine physicians, pathologists, radiologists, radiation oncologists, and medical oncologists. It is important for nonspecialists to recognize and refer patients with DTC who will benefit from a specialized approach. Recent advances in knowledge and changes in management of DTC call for the need to raise awareness on the part of these nonspecialist physicians, including general endocrinologists and medical oncologists at large. We provide an overview of diagnostic and therapeutic principles in DTC, especially those that bear direct implication on day-to-day management of these patients by generalists. Patients with DTC may be broadly categorized as having localized, locally persistent/recurrent, or metastatic disease. Current recommendations for DTC include a three-tiered system that classifies patients with localized disease into low, intermediate, or high risk of persistent or recurrent disease. Risk stratification should be performed at baseline and repeated on an ongoing basis, depending on clinical evolution. One of the overarching goals in the management of DTC is the need to personalize treatment by tailoring its modality and intensity according to ongoing prognostic stratification, evolving knowledge about the disease, and patient characteristics and preference. In metastatic disease that is refractory to radioactive iodine, thyroid tumors are being reclassified into molecular subtypes that better reflect their biological properties and for which molecular alterations can be targeted with specific agents.

ABSTRACT This work aimed to systematically review the literature to assess the effect of stretching on muscle strength in healthy people. The PubMed, Scopus and Scielo data sources were consulted, using the eligibility criteria: intervention with stretching and measurement of muscle strength performance in healthy people. Eighteen studies that met the criteria were included. The types of stretching used were continuous static 20%, intermittent static 60% and dynamic 20%. The types of strength evaluated were: maximum isometric strength (12.5%), maximum dynamic strength (66.66%) and muscle power (20.83%). 5.5% of the studies demonstrated increased muscle strength after stretching; 38.8% showed reduction after static stretching; 38.8% did not observe changes; and 16.6% had increased or reduced muscle strength depending on the type of stretching used. Based on the studies analyzed, performing static stretching prior to training, various manifestations of strength tended to reduce or not change muscle performance. It was not found a clear sign that the stretching performed before the strength training promotes an improvement in muscle performance.

RESUMO O presente trabalho teve por objetivo revisar sistematicamente a literatura, para avaliar o efeito do alongamento sobre a força muscular de pessoas saudáveis. Foram consultadas as fontes de dados: PubMed, Scopus e Scielo, utilizando-se os critérios de elegibilidade: intervenção com alongamento e medida de desempenho da força muscular, em pessoas saudáveis. Foram incluídos 18 estudos, que atenderam os critérios. Os tipos de alongamento utilizados foram o estático contínuo 20%, estático intermitente 60% e o dinâmico 20%. Os tipos de força avaliados foram: força máxima isométrica (12,5%), força máxima dinâmica (66,66%) e potência muscular (20,83%). 5,5% dos estudos demonstraram aumento da força muscular após o alongamento; 38,8% apresentaram redução, após o alongamento estático; 38,8% não observaram alteração; e 16,6% apresentaram aumento ou redução da força muscular dependendo do tipo de alongamento utilizado. Com base nos trabalhos analisados à realização de alongamento estático de forma prévia ao treinamento de diversas manifestações de força tenderam a reduzir ou não alterar o desempenho muscular. Não foi encontrada uma sinalização clara que o alongamento realizado antes do treino de força promova uma melhora de rendimento muscular.

Abstract Basic information about growth rate and response to silvicultural treatments on potential native species are bottlenecks for the wide use of these species for forest production. In this context, the objective of this work was to evaluate the silvicultural performance of four native species as a function of pruning intensity. The experimental design was completely randomized with ten replications and one plant per plot, in a 4 x 4 factorial scheme, four forest species, and four pruning intensities. At 30 and 42 months, height (H) and diameter at breast height (DBH) were evaluated, then the current annual increment (CAI) was calculated, as well as the mean annual increment (MAI) at 42 months. Guazuma ulmifolia showed higher growth in height and DBH compared to other species at both ages. The pruning resulted in a reduction of MAI in 0.15 cm. year-1 in DBH for every 25% of pruning intensity.

Abstract Acrocarpus fraxinifolius stands out due to its uses in the timber industry and rapid growth. However, information is scarce regarding its fertilization. We aim to understand how soil preparation and phosphorus doses affect A. fraxinifolius initial development. The experimental design used was a randomized block design in a 2 x 5 factorial scheme, consisting of two types of soil tillage (minimum and conventional) and five doses of phosphorus (P) (0, 50, 100, 150, and 200 g of simple superphosphate) with four replications, and plots formed by two plants. The measurement occurs at 30 and 210 days after planting, assessing the height and diameter at the stem height. Initially, the minimum tillage provided had a higher average height and diameter. However, conventional tillage, acidity correction, and fertilization with 108 g of simple superphosphate per plant resulted in Acrocarpus fraxinifolius plants with better growth at 210 days after planting.

Resumo O uso de polímeros hidrorretentores surge como uma alternativa para disponibilizar água de forma adequada na fase de implantação de povoamentos florestais, além de reter nutrientes necessários para o estabelecimento e desenvolvimento destes. No presente trabalho, objetivou-se avaliar o efeito do polímero hidrorretentor e a influência de diferentes doses de fertilização mineral no crescimento, teor e acúmulo de nutrientes do híbrido clonal de Eucalyptus urophylla x Eucalyptus grandis, na fase de implantação. O experimento foi realizado em delineamento de blocos casualizados completos, em esquema fatorial 2 x 5, sendo duas doses do polímero (0 e 1 g planta-1) e cinco combinações de fertilização mineral (N0P0K0, N0P1K0, N1P0K1, N1P1K1 e N2P2K2, correspondendo à dose de N (N0 = 0, N1 = 62 e N2 = 124 g do fertilizante por planta), P (P0 = 0, P1 = 75 e P2 = 150 g do fertilizante por planta) e K (K0 = 0, K1 = 62 e K2 = 124 g do fertilizante planta)), em três repetições com cinco plantas por parcela. As avaliações foram realizadas aos 30, 60, 120 e 150 dias pós-plantio, quando foram mensurados a altura total e o diâmetro do colo, além da análise química nutricional, aos 150 dias. A partir dos dados obtidos, observou-se que não houve interação entre o efeito do polímero e doses de fertilização mineral. Para o diâmetro do colo, o uso do polímero proporcionou maior crescimento às mudas somente nos 30 primeiros dias de avaliação, e para altura houve maior crescimento nas avaliações aos 30, 60 e 120 dias de plantio. Os tratamentos contendo fósforo (18% de P2O5) obtiveram maior incremento em diâmetro em relação aos demais nos primeiros 60 dias pós-plantio. Nas outras avaliações, a maior dose de fertilizante (N2P2K2) foi responsável pelo maior crescimento em diâmetro e altura. A maior dose de fertilização mineral promoveu maior acúmulo de NPK na parte aérea das plantas (caule, ramos e folhas). Portanto, o polímero proporcionou maior crescimento às mudas na fase inicial de desenvolvimento, e o fósforo se mostrou essencial para o crescimento em diâmetro e altura na fase de implantação do híbrido utilizado.

Abstract The use of water retaining polymer appears as an alternative to provide adequate water the phase of implantation the forest stands, further retaining nutrients necessary for the establishment and development of these. The objective of this study was to evaluate the effect of the water retaining polymer and influence of the different forms of mineral fertilization at growth, content and nutrient accumulation of a clonal hybrid of Eucalyptus urophylla x Eucalyptus grandis in the implantation phase. The experiment was carried out in a randomized complete block design at 2 x 5 factorial scheme, with two polymer doses (0 and 1 g plant-1) and five mineral fertilization combinations (N0P0K0, N0P1K0, N1P0K1, N1P1K1 e N2P2K2, corresponding to the dose of N (N0 = 0, N1 = 62 e N2 = 124 g of fertilizer per plant), P (P0 = 0, P1 = 75 e P2 = 150 g of fertilizer per plant) e K (K0 = 0, K1 = 62 e K2 = 124 g of fertilizer per plant)) in three replications with five plants per plot. The valuates were performed at 30, 60, 120 and 150 days post-planting, when total height and root collar diameter were measured, as well as nutritional chemical analysis, at 150 days. From the obtained data, observed that there was no interaction between the effect of the polymer and doses of mineral fertilization. For the root collar diameter use of the polymer only provided bigger growth seedlings at 30 days the evaluate, and for the height, there was greater growth in the valuates in the 30, 60 and 120 days of planting. The phosphorus treatments were obtained a bigger increment to the diameter in relation for the others 60 days after planting. These the other evaluations of higher fertilizer dosage (N2P2K2) was responsible for the greater growth in diameter and height. The higher dosage of mineral fertilization promoted greater accumulation at NPK in the aerial part of the plants (stem, branches e leaves). Therefore, the polymer gave a higher growth seedling in the initial phase development, and the phosphorus was shown to be essential for the growth in diameter and height in the phase of implantation of the hybrid used.
