ABSTRACT One of the challenges in the peach palm production system is the interpretation of leaf analyses and the adaptation of fertilization recommendations. Tools that enhance fertilizer use efficiency are therefore needed. This study aimed to establish norms for evaluating the nutrient status of peach palms using the Diagnosis and Recommendation Integrated System (DRIS) and to determine the adequate number of palm heart samples necessary for a more accurate assessment of productivity. Production, leaf nutrient content, and soil fertility data were collected from 102 commercial stands of peach palm in the Ribeira Valley, state of São Paulo, Brazil, between 2015 and 2020. Adequate number of individual samples (palm hearts) to be collected per stand for productivity assessment was estimated. DRIS norms were established by dividing the database into high-yield (reference population) and low-yield subpopulations, using average productivity as a criterion. By assuming an acceptable error of 5 to 10 % for the assessment of peach palm productivity, taking into account total palm heart weight and/or the weight of cylinders, respectively, 16 plants per stand should be sampled. DRIS was not sensitive enough to diagnose differences in the probability of positive response to fertilization; however, the P, K, Ca, Mg, S, B, Fe, Cu, Mn and Zn contents were positively correlated with the respective nutrient indices. recommendations needed (DRIS Production content Valley Paulo Brazil 201 2020 hearts estimated highyield high yield reference population lowyield low subpopulations criterion 1 andor or cylinders respectively sampled however P K Ca Mg S B Fe Cu indices 20 202 2

Abstract Professional drivers show a higher prevalence of obstructive sleep apnea (OSA) compared with the general population. OSA has been widely associated with an increased risk of traffic accidents. This article aims to investigate the presence of risk factors for OSA, its prevalence and the value of screening tools in a truck drivers’ cohort. Descriptive and analytical prospective study. Demographic, anthropometric, Epworth Sleepiness Scale, STOP-Bang and Berlin Questionnaire were used to select subjects with suspicion of OSA. Polysomnography (PSG) was performed in individuals with positive screening. Mean age was 44.6±7 years, mean body mass index was 28.7±4 kg/m². Of the 281 truck drivers screened, 88 were positive for potential OSA. Of these, 63 completed PSG study and the diagnosis was confirmed in 85.7% (prevalence of 19.2%). The following variables showed a positive correlation with the apnea-hypopnea index: neck circumference and STOP-Bang. The combination of a predominantly male population, obesity, age distribution and lifestyle could account for the high prevalence of OSA in this specific population. Questionnaires proved to be a valuable screening tool. Screening, treatment, and management of OSA should be a priority as a public safety policy.

Este artigo tem por objetivos investigar fatores de risco de SAOS, estimar a sua prevalência e o valor de instrumentos de rastreio numa amostra de motoristas de pesados. Estudo prospetivo descritivo e analítico. Rastreio realizado com recurso a dados demográficos, antropométricos, Escala de Sonolência de Epworth, STOP-Bang e Questionário de Berlim. Nos indivíduos com rastreio positivo foi realizada polissonografia (PSG). A idade média era de 44,6±7 anos, índice de massa corporal 28,7±4 kg/m². Dos 281 motoristas incluídos, 88 apresentavam risco elevado de SAOS. Destes, 63 realizaram PSG, com confirmação diagnóstica em 85,7% (prevalência de 19,2%). O perímetro cervical e STOP-Bang apresentaram correlação positiva com o índice de apneia-hipopneia. A combinação de género predominantemente masculino, obesidade, distribuição de idade e estilo de vida pode justificar a elevada prevalência de SAOS nesta população. O uso de questionários é uma medida eficaz de rastreio. Nos motoristas, o rastreio e tratamento de SAOS deveria ser uma medida de saúde pública prioritária.

ABSTRACT. This study aimed to evaluate the nutrition of commercial soybean crops in an agricultural frontier region using the diagnosis and recommendation integrated system (DRIS) and compositional nutrient diagnosis (CND) methods, as well as identify sufficiency ranges. The study was performed by collecting leaf samples (third trifoliate leaf without petiole) at flowering from commercial soybean crops in the states of Piauí and Maranhão, Brazil, and evaluating the crop yield by analyzing macro- and micronutrients in the plant tissue of 98 samples. The DRIS and CND methods were applied based on the cataloged data, followed by the generation of norms, analysis of relationships between yield and nutrients (selecting high-yield crops by the cumulative function of the data), generation of sufficiency ranges, and comparison of methods. The relationships obtained by the DRIS and CND indices with the yield and nutrients were significant, indicating that both methods can be employed for the evaluation of leaf nutrients in soybean. The sufficiency ranges from the DRIS and CND methods presented superior nutrient ranges in relation to the values proposed in the literature for macronutrients, except for nitrogen, and greater range amplitudes for micronutrients. ABSTRACT (DRIS (CND third petiole Maranhão Brazil macro 9 data norms selecting highyield high , data) significant macronutrients nitrogen

Abstract Choked banana presents closeness of petioles looks that allows the exit of the distal part of the inflorescence, but not the basal part is stuck up at the throat. The aim of this study was to avaluate the effect of choking on the growth of Musa spp. cv Nanica, as well as to investigate how the climatic variations and status nutritional of plants are associated whith this physiological disorder. The experiment was conducted in September/2018 in August/2019 in Registro, São Paulo state, Brazil. The experimental design adopted was completely randomized with two treatments and ten repetitions, in sub-divided plots over time (months). The evaluation consisted in determining the intensity of the symptom, number of leaves, plant height, hand number, stalk length, symptoms of nutritional deficiency and other abnormalities, leaf nutrient contents. Plant growth was not impacted by choking, only the hands number in the months of October/2018 and June/2019 to August/2019 (p< 0.05). Choking occurred throughout the year, with a predominance of severe symptoms of April in June due a redução da temperatura e radiation. The twisted fruits, united by fusion of floral parts and with different sizes occurred, respectively, in 21.67, 60.83 and 17.52% of the symptomatic plants, associated with the cool temperature during the differentiation of the female fruit. Choking and abnormalities in the bunch and fruits were associated with Zn deficiency (p< 0.05). The deficiency of Ca at low temperatures, the lower availability of radiation and the high relative humidity were also associated with the choking. The excess of P in the soil, as well, the adverse climatic conditions contributed to the limitation of these nutrients.

Resumen El arrepollamiento del banano ahogado acorta la distancia entre pecíolos de hojas alternas, lo que permite la salida de la parte distal de la inflorescencia; sin embargo, la parte basal se atasca en la garganta. Se evaluó el efecto del arrepollamiento en el crecimiento de Musa spp. cv Nanica (AAA) y la relación de las variaciones climáticas y el estado nutricional con este trastorno fisiológico fueron determinados. El experimento se llevó a cabo de septiembre 2018 a agosto 2019 en Registro, estado de São Paulo, Brasil. El diseño experimental fue completamente al azar con dos tratamientos y diez repeticiones, en parcelas subdivididas en el tiempo (meses). La evaluación consistió en determinar la intensidad del síntoma, número de hojas, altura de la planta, número de manos, longitud del tallo, síntomas de deficiencia nutricional y otras anomalías, contenido de nutrientes de las hojas. El crecimiento de las plantas no se vio afectado por el arrepollamiento, solo el número de manos en los meses de octubre 2018 y junio 2019 a agosto 2019 (p< 0.05). El arrepollamiento ocurrió durante todo el año, con predominio de síntomas severos de abril a junio debido a una reducción de la temperatura y radiación. Los frutos torcidos, unidos por fusión de partes florales y con diferentes tamaños ocurrieron, respectivamente, en 21.67, 60.83 y 17.52% de las plantas sintomáticas, asociados con la temperatura fresca durante la diferenciación de la fruta femenina. El arrepollamiento, así como anormalidades en el racimo y las frutas se relacionaron con deficiencia de Zn (p< 0.05). La deficiencia de Ca a bajas temperaturas, la menor disponibilidad de radiación y la alta humedad relativa también se asociaron con el arrepollamiento. El exceso de P en el suelo, así como las condiciones climáticas adversas contribuyeron a la limitación de estos nutrientes.

Abstract: Castleman Disease is a lymphoproliferative disorder that is classified clinically as unicentric or multicentric, and histologically as hyaline vascular variant or plasma cell variant. The unicentric Castleman Disease often presents as an incidental mediastinal mass, but the involvement of the pulmonary hilum is rare.

Resumo: A Doença de Castleman é uma doença linfoproliferativa, podendo classificar-se clinicamente como unicêntrica ou multicêntrica, e histologicamente como variante hialino-vascular ou variante de células plasmáticas. A Doença de Castleman unicêntrica apresenta-se frequentemente como uma massa mediastínica incidental, contudo o envolvimento pulmonar hilar é raro.

RESUMO: O plasma rico em plaquetas (PRP) consiste em uma alta concentração de plaquetas em um pequeno volume de plasma, sendo, em média, quatro vezes maior que a concentração sérica. O uso de PRP é justificado pela alta concentração de fatores de crescimento presentes em grânulos no interior das plaquetas, que possuem diversas funções como proliferação celular, quimiotaxia, angiogênese e diferenciação celular, que ampliam o poder de reparação tecidual. Há diversos protocolos para obtenção do PRP em equinos descritos na literatura, dentre os quais destacam-se os de dupla centrifugação, os automatizados e os filtros. Há diferenças substanciais no conteúdo do PRP dependendo do seu método de obtenção, principalmente no que se diz respeito à quantidade de leucócitos, plaquetas e concentração de fatores de crescimento. Sendo assim, o objetivo deste estudo foi comparar a utilização do concentrado de plaquetas obtido por protocolo de dupla centrifugação e o obtido pelo filtro E-PET (Equine Platelet Enhancement Therapy), levando-se em consideração a concentração plaquetária e leucocitária final, a quantificação de fatores de crescimento (TGFβ e PDGF-BB) e a facilidade de realização entre tais métodos. Utilizou-se nove animais para a obtenção de PRP por dupla centrifugação e através do filtro E-PET, não havendo diferença estatística (p>0,05) entre os métodos de obtenção em relação à concentração plaquetária e leucocitária, entretanto, houve diferença estatística (p=0,002; p=0,004, respectivamente) em relação a concentração de TGFβ e PDGF-BB. Dessa forma, concluiu-se que o filtro E-PET mostrou-se um método mais efetivo, sendo possível sua utilização à campo, além de proporcionar uma maior concentração de fatores de crescimento TGFβ e PDGF-BB.

ABSTRACT: The platelet-rich plasma (PRP) consists of a high concentration of platelets in a small volume of plasma, four times greater (average) than the serum concentration. The use of PRP is justified by the high concentration of growth factors present in granules in the platelets, which have several functions such as cell proliferation, chemotaxis, angiogenesis and differenciation, which extend the power of tissue repair. There are several protocols to obtain PRP in horses described in the literature, among which are highlighted the double centrifugation, automated and filters. There are substantial differences in the PRP content depending on its method of production, especially when it concerns the amount of leukocytes, platelets and concentration of growth factors. Thus, the aim of this study was to compare the use of platelet concentrates obtained by double centrifugation protocol and obtained by the filter E-PET (Equine Platelet Enhancement Therapy) taking into account the platelet and leukocyte final concentration, the quantification of growth factors (TGFβ and PDGF-BB) and the facility to do those methods. Nine horses were used to obtain PRP by double centrifugation and through the E-PET filter, with no statistical difference (p>0.05) between the methods relative to the platelet and leukocyte concentration; however, there was statistical difference (p=0.002 and p=0.004 respectively) compared with the concentration of TGFβ and PDGF-BB. It was concluded that the E-PET filter proved to be a more effective method possible to use in the field and to provide a higher concentration of growth factors (TGFβ and PDGF-BB).
