Abstract Frequency Selective Surfaces (FSS) are increasingly being used in telecommunications systems due to the numerous advantages presented by this sort of structure, among them low cost, ease of fabrication, and low profile stand out. This work reports the design, fabrication, and characterization of a multilayer frequency-selective absorber (FSA) for broadband operation. The proposed structure shows an absorption performance (operating in the frequency range between 2 GHz and 6 GHz) within the transmission band. The absorber consists of cascaded frequency selective surfaces, which are composed of both conductive square loops, which reflect incident signals, and resistive ones, which act as an absorbing layer. To verify the absorbing structure performance, full-wave numerical simulations and measurements are presented. The measured results are in good agreement with the numerical ones and show that the design performs absorption above 80% within the range of 2.48 GHz to 6.13 GHz, which verifies the project properties. Besides that, numerical results show that the proposed absorber has a proper response under oblique incidence up to 30°.

Abstract Healthcare workers present an increased risk of contagion for the SARS-CoV-2 virus due to their labor exposure. Here, we describe the clinical, laboratory, and immunological characteristics of healthcare workers, before vaccine application, exposed to SARS-CoV-2-infected patients. We collected sociodemographic, clinical, and laboratory information from 50 professionals who worked during the COVID-19 pandemic at the Clinical Hospital of the Northwest in Brazil. The results showed that most workers are women, over 50 years old, and worked as nursing technicians. Approximately 56% of workers were positive for a previous infection by RT-PCR and/or anti-SARS-CoV-2-immunoglobulin tests. Increased levels of hematocrit, neutrophils, NK lymphocytes, and fibrinogen, were found in positive healthcare workers, suggesting a light inflammatory status. The immunological findings showed an increase in IL-17 production and a Th2/Th17/Th22 profile followed by high serology for anti-SARS-CoV-2 IgM and IgG. Those data reveal the importance of studies with healthcare workers to investigate if the continuous exposition to the virus may result in chronic activation of the immune system and/or pulmonary inflammation in this target group.

RESUMO A irregularidade das chuvas na região semiárida do Brasil e do mundo exerce ação limitante na produção agrícola, em geral, inclusive das espécies frutíferas. Nessas condições, a irrigação é o insumo que mantém o sistema produtivo com viabilidade econômica e social. O estudo foi desenvolvido no período de 2012 a 2014, no município de Remígio, Estado da Paraíba, Brasil, com o objetivo de avaliar a produção de gravioleira ‘Morada’ cultivada em condições de sequeiro e irrigada, no solo sem e com cobertura morta em duas safras. Os tratamentos foram distribuídos em blocos casualizados com três repetições, em arranjo fatorial 2 × 3 × 2, relativos às plantas não irrigadas (lâmina de 0 mm) e irrigadas semanalmente (lâmina de 17,2 mm) no solo sem cobertura, com cobertura a partir de restos de culturas e com bagaço de sisal nas safras agrícolas de 2012/2013 e 2013/2014. No solo sem cobertura a irrigação elevou a produtividade de 5,3 para 34,7 t ha-1 na primeira safra e de 9,4 para 57,7 t ha-1 na segunda safra. O uso conjunto da irrigação e a cobertura com resíduo de sisal proporcionou as maiores produtividades. O uso do resíduo de sisal como cobertura morta aumentou o número e a massa média de frutos, a produção por planta e a produtividade da gravioleira ‘Morada’ em relação ao solo sem cobertura e coberto por resíduos culturais.
ABSTRACT Irregular rainfall in the semiarid region of Brazil and in the world exerts a limiting action on agricultural production, in general, including fruit species. Under these conditions, irrigation is the input that keeps the production system both economically and socially viable. This study was carried out from 2012 to 2014, in the municipality of Remígio, Paraíba State, Brazil, aiming at evaluating the production of ‘Morada’ soursop cultivated under rainfed and irrigated conditions, in soil with and without mulch, in two harvests. The treatments were distributed in randomized block design with three replicates in a 2 × 3 × 2 factorial scheme, corresponding to non-irrigated plants (0 mm water depth) and plants irrigated weekly (17.2 mm water depth) in soil without mulching, with cover crop residues, and with a sisal bagasse mulch in the 2012/2013 and 2013/2014 crop years. In the soil without mulching, irrigation increased yield from 5.3 to 34.7 t ha-1 in the first harvest and from 9.4 to 57.7 t ha-1 in the second harvest. The association between irrigation and mulch with sisal residue promoted the highest yield. The use of mulch of sisal residue increased the number and mean mass of fruits, production per plant and yield of ‘Morada’ soursop compared to the soil without mulch and covered by crop residues.

RESUMO Objetivo: Descrever as práticas de ressuscitação volêmica em unidades de terapia intensiva brasileiras e compará-las com as de outros países participantes do estudo Fluid-TRIPS. Métodos: Este foi um estudo observacional transversal, prospectivo e internacional, de uma amostra de conveniência de unidades de terapia intensiva de 27 países (inclusive o Brasil), com utilização da base de dados Fluid-TRIPS compilada em 2014. Descrevemos os padrões de ressuscitação volêmica utilizados no Brasil em comparação com os de outros países e identificamos os fatores associados com a escolha dos fluidos. Resultados: No dia do estudo, foram incluídos 3.214 pacientes do Brasil e 3.493 pacientes de outros países, dos quais, respectivamente, 16,1% e 26,8% (p < 0,001) receberam fluidos. A principal indicação para ressuscitação volêmica foi comprometimento da perfusão e/ou baixo débito cardíaco (Brasil 71,7% versus outros países 56,4%; p < 0,001). No Brasil, a percentagem de pacientes que receberam soluções cristaloides foi mais elevada (97,7% versus 76,8%; p < 0,001), e solução de cloreto de sódio a 0,9% foi o cristaloide mais comumente utilizado (62,5% versus 27,1%; p < 0,001). A análise multivariada sugeriu que os níveis de albumina se associaram com o uso tanto de cristaloides quanto de coloides, enquanto o tipo de prescritor dos fluidos se associou apenas com o uso de cristaloides. Conclusão: Nossos resultados sugerem que cristaloides são usados mais frequentemente do que coloides para ressuscitação no Brasil, e essa discrepância, em termos de frequências, é mais elevada do que em outros países. A solução de cloreto de sódio 0,9% foi o cristaloide mais frequentemente prescrito. Os níveis de albumina sérica e o tipo de prescritor de fluidos foram os fatores associados com a escolha de cristaloides ou coloides para a prescrição de fluidos.
Abstract Objective: To describe fluid resuscitation practices in Brazilian intensive care units and to compare them with those of other countries participating in the Fluid-TRIPS. Methods: This was a prospective, international, cross-sectional, observational study in a convenience sample of intensive care units in 27 countries (including Brazil) using the Fluid-TRIPS database compiled in 2014. We described the patterns of fluid resuscitation use in Brazil compared with those in other countries and identified the factors associated with fluid choice. Results: On the study day, 3,214 patients in Brazil and 3,493 patients in other countries were included, of whom 16.1% and 26.8% (p < 0.001) received fluids, respectively. The main indication for fluid resuscitation was impaired perfusion and/or low cardiac output (Brazil: 71.7% versus other countries: 56.4%, p < 0.001). In Brazil, the percentage of patients receiving crystalloid solutions was higher (97.7% versus 76.8%, p < 0.001), and 0.9% sodium chloride was the most commonly used crystalloid (62.5% versus 27.1%, p < 0.001). The multivariable analysis suggested that the albumin levels were associated with the use of both crystalloids and colloids, whereas the type of fluid prescriber was associated with crystalloid use only. Conclusion: Our results suggest that crystalloids are more frequently used than colloids for fluid resuscitation in Brazil, and this discrepancy in frequencies is higher than that in other countries. Sodium chloride (0.9%) was the crystalloid most commonly prescribed. Serum albumin levels and the type of fluid prescriber were the factors associated with the choice of crystalloids or colloids for fluid resuscitation.

OBJECTIVES: To prospectively evaluate demographic, anthropometric and health-related quality of life (HRQoL) in pediatric patients with laboratory-confirmed coronavirus disease 2019 (COVID-19) METHODS: This was a longitudinal observational study of surviving pediatric post-COVID-19 patients (n=53) and pediatric subjects without laboratory-confirmed COVID-19 included as controls (n=52) was performed. RESULTS: The median duration between COVID-19 diagnosis (n=53) and follow-up was 4.4 months (0.8-10.7). Twenty-three of 53 (43%) patients reported at least one persistent symptom at the longitudinal follow-up visit and 12/53 (23%) had long COVID-19, with at least one symptom lasting for >12 weeks. The most frequently reported symptoms at the longitudinal follow-up visit were headache (19%), severe recurrent headache (9%), tiredness (9%), dyspnea (8%), and concentration difficulty (4%). At the longitudinal follow-up visit, the frequencies of anemia (11% versus 0%, p=0.030), lymphopenia (42% versus 18%, p=0.020), C-reactive protein level of >30 mg/L (35% versus 0%, p=0.0001), and D-dimer level of >1000 ng/mL (43% versus 6%, p=0.0004) significantly reduced compared with baseline values. Chest X-ray abnormalities (11% versus 2%, p=0.178) and cardiac alterations on echocardiogram (33% versus 22%, p=0.462) were similar at both visits. Comparison of characteristic data between patients with COVID-19 at the longitudinal follow-up visit and controls showed similar age (p=0.962), proportion of male sex (p=0.907), ethnicity (p=0.566), family minimum monthly wage (p=0.664), body mass index (p=0.601), and pediatric pre-existing chronic conditions (p=1.000). The Pediatric Quality of Live Inventory 4.0 scores, median physical score (69 [0-100] versus 81 [34-100], p=0.012), and school score (60 [15-100] versus 70 [15-95], p=0.028) were significantly lower in pediatric patients with COVID-19 at the longitudinal follow-up visit than in controls. CONCLUSIONS: Pediatric patients with COVID-19 showed a longitudinal impact on HRQoL parameters, particularly in physical/school domains, reinforcing the need for a prospective multidisciplinary approach for these patients. These data highlight the importance of closer monitoring of children and adolescents by the clinical team after COVID-19.

Abstract Fifty-five watermelon accessions were inoculated in pots using Fusarium oxysporum f. sp. niveum chlamydospores in a completely randomized design with five replications. Among the 42 accessions that were resistant, twelve accessions with a mean score ≤1 were selected for morpho-agronomic characterization. ‘Sugar Baby’ and ‘Charleston Gray’ were used as controls. Field research was conducted over two production cycles in a randomized block design with three replications and five plants per plot. For the characterization 13 quantitative agronomic traits were used. The dissimilarity measures were obtained by the sum of the matrices of standardized mean Euclidean distance. Coefficients of variation ranged from 5.33% (number of days until 50% of plants with at least one female flower) and 17.20% (mass of characterized fruit). In the second cycle, a reduction in days was observed for the flowering. For soluble solids content, the accession BGH-UNIVASF 40 was statistically equal to the commercial cultivars in the second cycle. Accessions were grouped similarly using two grouping methods, Tocher and the farthest neighbor method. The most promising accessions were BGH-UNIVASF 40, 169, 177 and 210 for use in future hybridizations. BGH-UNIVASF 76, 128 and 185 (Citrullus lanatus var. citroides) can be used as resistant Fusarium wilt rootstocks.

RESUMO: A ingestão de corpos estranho de origem metálica e/ou pontiagudos desencadeia em bovinos, quadros de Reticuloperitonite Traumática e suas sequelas. Dentre as quais podemos destacar a retículo esplenite traumática cuja letalidade é elevada, embora a mesma apresente uma baixa frequência na clínica de ruminantes. Portanto, baseado na escassez de informações sobre esta enfermidade, este trabalho teve por objetivo avaliar os achados clínicos, laboratoriais, ultrassonográficos e anatomopatológicos de 30 bovinos adultos diagnosticados com retículo esplenite traumática. Os achados clínicos, ultrassonográfico e anatomopatológico foram analisados por meio de estatística descritiva, e os dados laboratoriais foram avaliados utilizando-se as medidas de tendência central. Clinicamente os animais apresentaram desidratação e alterações no comportamento, apetite e na motilidade ruminal. Os achados hematológicos revelaram leucocitose (37077.17±25004.59cell/μL) por neutrofilia com desvio à esquerda regenerativo e hiperfibrinogenemia (1130±364.98mg/dL). O exame ultrassonográfico possibilitou a visualização de filamentos móveis e ecogênicos que corresponderam à presença de aderências fibrinosas, observou-se também, deslocamento do retículo e irregularidade no seu contorno além das alterações na quantidade, padrão e amplitude das contrações reticulares. Permitiu ainda, a constatação de alterações esplênicas como abscessos que foram caracterizados como estruturas circulares de variados tamanhos delimitada por capsula contendo no seu interior conteúdo de ecogenicidade variável. Trombose da veia esplênica e dobramento do baço. Os resultados obtidos nesse trabalho, indicaram que a retículo esplenite traumática causa sinais clínicos inespecíficos, severas alterações laboratoriais e principalmente que a ultrassonografia é um método eficiente para o diagnóstico dessa enfermidade uma vez que as lesões anatomopatológicas confirmaram os achados ultrassonográficos.
ABSTRACT: Ingestion of metallic and/or sharp foreign bodies triggers cases of traumatic reticuloperitonitis and its sequelae in cattle. Among these sequelae, we can highlight traumatic reticulosplenitis, that has high mortality, although its frequency in the ruminant medicine is low. Therefore, based on the scarcity of information on this disease, the current study aimed to evaluate the clinical, laboratory, ultrasonographic, and pathological findings of 30 adult cattle diagnosed with traumatic reticulosplenitis. Clinical, ultrasound, and anatomopathological findings were analyzed using descriptive statistics and laboratory data were evaluated using measures of central tendency. Clinically the animals presented dehydration and alterations in behavior, appetite, and ruminal motility. Hematological findings revealed neutrophilic leukocytosis (37077.17±25004.59cell/μL) with regenerative left shift and hyperfibrinogenemia (1130±364.98mg/dL). The ultrasound examination enabled visualization of mobile and echogenic filaments that corresponded to the presence of fibrin adhesions. Displacement of the reticulum and irregularity in its contour, as well as alterations in the quantity, pattern, and amplitude of reticular contractions were also observed. Splenic alterations such as abscesses were found, characterized as circular structures of varying sizes delimited by capsules containing variable echogenicity. Splenic vein thrombosis and spleen folding were also observed. The results obtained in the current study indicated that traumatic reticulosplenitis causes nonspecific clinical signs, severe laboratory alterations and, mainly, that ultrasound is an efficient method for the diagnosis of this disease, since the anatomopathological lesions confirmed the ultrasound findings.

Abstract In this paper, a double layer stopband Frequency Selective Surface (FSS) for Ultra-Wide Band (UWB) applications is presented. The proposed FSS consists of two cascaded conventional FSS, one with double square loops and other with square loops. The − 10dB frequency band from 3.00 GHz to 11.64 GHz is achieved, with a fractional bandwidth of 149 %. Effects of angular stability and polarization independence over the frequency response are investigated and conclusions are presented. In order to show transmission performance, the FSS was simulated by ANSYS HFSS. The FSS shows angular stability and polarization independence in entire UWB band (3.10 – 10.60 GHz). A prototype was built and measurements were performed. A good agreement between simulated and measured results was observed.

ABSTRACT Prolactinomas are the most common pituitary adenomas (approximately 40% of cases), and they represent an important cause of hypogonadism and infertility in both sexes. The magnitude of prolactin (PRL) elevation can be useful in determining the etiology of hyperprolactinemia. Indeed, PRL levels > 250 ng/mL are highly suggestive of the presence of a prolactinoma. In contrast, most patients with stalk dysfunction, drug-induced hyperprolactinemia or systemic diseases present with PRL levels < 100 ng/mL. However, exceptions to these rules are not rare. On the other hand, among patients with macroprolactinomas (MACs), artificially low PRL levels may result from the so-called “hook effect”. Patients harboring cystic MACs may also present with a mild PRL elevation. The screening for macroprolactin is mostly indicated for asymptomatic patients and those with apparent idiopathic hyperprolactinemia. Dopamine agonists (DAs) are the treatment of choice for prolactinomas, particularly cabergoline, which is more effective and better tolerated than bromocriptine. After 2 years of successful treatment, DA withdrawal should be considered in all cases of microprolactinomas and in selected cases of MACs. In this publication, the goal of the Neuroendocrinology Department of the Brazilian Society of Endocrinology and Metabolism (SBEM) is to provide a review of the diagnosis and treatment of hyperprolactinemia and prolactinomas, emphasizing controversial issues regarding these topics. This review is based on data published in the literature and the authors' experience.

ABSTRACT: The aim of this research was to evaluate the effect of distinct levels of salinity on the evapotranspiration of the RB867515, RB855453, RB92579 and RB928064 sugarcane cultivars. The evapotranspiration was monitored during daytime period under meteorological conditions influenced, mainly by cloud variations. The salinity values were established by addition of 0, 50, 100 and 150 mM of Sodium Chloride (NaCl) to the nutrient solution, which was applied by fertigation, in such way that the electrical conductivity (EC) of the leached solution was near 3, 6, 10 and 13 dS m−1, respectively. The increase of the NaCl concentration in the nutrient solution affected, significantly and in a linear manner, the evapotranspiration of all sugarcane cultivars, such that the days with low cloud provided the highest evapotranspiration values and the greater reduction among salinity levels. Analysis of the evapotranspiration accumulated during the daytime period showed that there were no significant differences among sugarcane cultivars and that, under the highest atmospheric water demand, the evapotranspiration decreased 48.5 g plant−1 EC−1. This value represents the average reduction of 5.1% EC−1 when compared to the treatment without NaCl, considering data of all cultivars.

Abstract In this paper, we use a novel convoluted geometry to design a dual-band FSS with angular stability and independent polarization operation. The geometry allows the design of a dual-band FSS to block ISM and UNII radio bands. We performed a parametric study with the commercial software ANSYS HFSS. A prototype of our proposed FSS design was built and its transmission characteristics were measured and compared with simulated results. We observed good agreement between numerical and experimental results. The proposed FSS realized a dual-band response at the required bands and it had angular stability and polarization independence.

RESUMO Os escorpiões de interesse médico no Brasil pertencem ao gênero Tityus. Dentre eles, Tityus stigmurus é o principal responsável por picadas de escorpião na região Nordeste. Após uma picada, a peçonha de escorpião se distribui rapidamente para os órgãos, atingindo os rins depressa. Entretanto, há poucos trabalhos sobre fisiopatologia renal do envenenamento por escorpiões. Neste trabalho, avaliamos os efeitos da peçonha de T. stigmurus (TsV) sobre parâmetros renais em rins de ratos isolados. Ratos Wistar (n = 6), pesando 250-300 g, foram perfundidos com solução de Krebs-Henseleit contendo 6 g/100 mL de albumina de soro bovino. TsV nas concentrações de 0,3 e 1,0 μg/mL foi testado e os efeitos sobre a pressão de perfusão (PP), resistência vascular renal (RVR), fluxo urinário (FU), taxa de filtração glomerular (TFG) e excreção de eletrólitos foram analisados. Apenas na concentração de 1,0 μg/mL de TsV foram observados efeitos que aumentaram PP (controlePP40' = 92,7 ± 1,95; TsVPP40' = 182,0 ± 4,70 mmHg*, *p < 0,05), RVR (controleRVR40' = 3,28 ± 0,23 mmHg; TstRVR40' = 6,76 ± 0,45 mmHg*, *p < 0,05), FU (controleFU50' = 0,16 ± 0,04; TstFU50' = 0,60 ± 0,10 mL/g/min*, *p < 0,05), a TFG e excreção de eletrólitos, com alterações histológicas que indicam de lesão renal tubular. Em conclusão, peçonha de T. stigmurus induz um aumento transiente da PP com lesão tubular, ambos os quais conduzem a uma excreção elevada de eletrólitos.
ABSTRACT Scorpions belonging to the Tityus genus are of medical interest in Brazil. Among them, Tityus stigmurus is the main scorpion responsible for stings in the Northeast region. After a sting, the scorpion venom distributes rapidly to the organs, reaching the kidneys quickly. However, there are few studies concerning the renal pathophysiology of scorpion poisoning. In this study, we evaluated the effects of T. stigmurus venom (TsV) on renal parameters in isolated rat kidneys. Wistar rats (n = 6), weighing 250-300 g, were perfused with Krebs-Henseleit solution containing 6 g/100 mL bovine serum albumin. TsV at 0.3 and 1.0 μg/mL was tested, and the effects on perfusion pressure (PP), renal vascular resistance (RVR), urinary flow (UF), glomerular filtration rate (GFR), and electrolyte excretion were analyzed. Effects were observed only at TsV concentration of 1.0 μg/mL, which increased PP (controlPP40' = 92.7 ± 1.95; TsVPP40' = 182.0 ± 4.70* mmHg, *p < 0.05), RVR (controlRVR40' = 3.28 ± 0.23 mmHg; TstRVR40' = 6.76 ± 0.45* mmHg, *p < 0.05), UF (controlUF50' = 0.16 ± 0.04; TstUF50' = 0.60 ± 0.10* mL/g/min,*p < 0.05), GFR and electrolyte excretion, with histological changes that indicate renal tubular injury. In conclusion, T. stigmurus venom induces a transient increase in PP with tubular injury, both of which lead to an augmented electrolyte excretion.
