Avaliação da altura facial inferior após expansão rápida da maxila

Clinicians have worried about the effect the rapid maxillay expansion (RME) might have on the lower face height (LFH). This study cephalometrically evaluated the LFH after RME, using two kinds of palatal expanders (Haas–G1 and Hyrax–nG2). The sample contained 93 lateral cephalograms from 31 brasilian patients, 15 females and 16 males; with a mean age of 13.2 years, and a range of 9-16 years. The cephalograms were taken before disjunction (T1), immediately after disjunction (T2) and after leveling (T3). G1 and G2 experienced similar changes in N-Me. S-Go didn’t change, but both groups showed gradative increases of values in T2 and T3. G1 and G2 displayed increased anterior and posterior LFH (Me-PP and GO-PP) in T2 and T3. After using both types of palatal expanders showed statistically significant increases in anterior and posterior LFH.O aumento que ocorre na altura facial inferior (AFI) após expansão rápida da maxila (ERM) preocupa os pesquisadores. Este estudo avaliou a AFI após ERM com dois disjuntores palatinos (Haas–G1 e Hyrax–G2). A amostra continha 93 telerradiografias em norma lateral, de 31 pacientes brasileiros, 15 do sexo feminino e 16 do masculino, e faixa etária entre 9 e 16 anos de idade (média=13a2m). Cada indivíduo foi radiografado pré-disjunção (T1), pós-disjunção (T2) e ao final do nivelamento (T3). A variável N-Me modificou de forma semelhante nos dois grupos; e a grandeza S-Go, não variou nos grupos, porém, seus valores aumentaram gradativamente nas fases T2 e T3. As grandezas PP-Me e PP-Go, mostraram, para G1 e G2, aumento da AFI anterior e posterior em T2 e T3. A AFI anterior e posterior aumentou estatisticamente com os dois aparelhos

Efeito de diferentes proporções de moinha de café na composição de substratos alternativos para produção de mudas de pepino

One of the main factors related to the quality of edible vegetable seedlings is the type of substrate used. The growth variables of cucumber seedlings grown on alternative substrates to the commercial substrate, having increasing levels of coffee drying residues (chaff). The experiment was conducted under a completely randomized design with six treatments and ten replications, where: T1: commercial substrate (CS); T2: 0% chaff (CH) + 40% carbonized rice husk (CRH) + 15% coconut fiber (CF) + 5% eggshell (ES) + 40% CS; T3: 10% CH + 40% CRH + 15% CF + 5% ES + 30% CS; T4: 20% CH + 40% CRH + 15% CF + 5% ES + 20% CS; T5: 30% CH + 40% CRH + 15% CF + 5% ES + 10% CS; T6: 40% CH + 40% CRH + 15% CF + 5% ES + 0% CS. The variables evaluated were electrical conductivity of substrates, dry mass of the root system and the aerial part, seedling height, stem diameter and number of leaves. Increasing proportions of chaff also increase the electrical conductivity of the substrate. Proportions around 15 to 20% of chaff in the composition of the substrate present the highest values of stem diameter, dry mass of the root system and of the aerial part. Proportions up to 30% of the substrate constituted by 40% rice husk, 15% coconut fiber, 5% egg husk and 10% commercial substrate can also be used without loss in the growth variables of cucumber seedlings.Um dos principais fatores relacionados à qualidade das mudas de olerícolas é o tipo de substrato utilizado. Avaliaram-se as variáveis de crescimento de mudas de pepino produzidas em substratos com níveis crescentes de resíduo da secagem dos grãos de café (moinha) em substituição ao uso exclusivo do substrato comercial. O experimento foi realizado no delineamento inteiramente casualizado, com seis tratamentos e dez repetições,  sendo: T1: Substrato comercial (SC); T2: 0% de moinha (MO)+ 40% de casca de arroz carbonizada (CAC) + 15% de fibra de coco (FC) + 5% de casca de ovo (CO) + 40% de SC; T3: 10% de MO + 40% de CAC + 15% de FC + 5% de CO+ 30% de SC; T4: 20% de MO+ 40% de CAC+ 15% de FC + 5% de CO + 20% de SC ; T5: 30% de MO + 40% de CAC + 15% de FC + 5% de CO + 10% de SC; T6: 40% de MO + 40% de CAC + 15% de FC + 5% CO + 0% SC. Avaliou-se condutividade elétrica dos substratos, matéria seca do sistema radicular e parte aérea, altura de plântula, diâmetro de caule e número de folhas. Proporções crescentes de moinha acarretam no aumento da condutividade elétrica do substrato. Proporções em torno de 15 a 20% de moinha na composição do substrato apresentam os maiores valores de matéria seca da parte aérea, de raiz e diâmetro do caule. Proporções de até 30% de moinha em substrato composto por 40% de CAC, 15% de FC, 5% de CO e 10% de SC, também podem ser utilizados sem que haja prejuízo nas variáveis de crescimento de mudas de pepino

FONTES DE ADUBOS ORGÂNICOS NA PRODUÇÃO DE MUDAS DE PITAIA

A pitaia (Hylocereus undatus) é uma frutífera exótica que vem se popularizando perante os produtores brasileiros. Com isso, verificou-se a utilização de duas fontes de esterco animal, como tratamentos compostos de solo de barranco + esterco de curral (2:1), solo de barranco  + esterco suíno curtido (2:1) e solo de barranco, onde todos foram enriquecidos com a dose de 2Kg m-3 de superfosfato simples. O experimento foi realizado no Setor de Viveiricultura do Ifes- Campus Santa Teresa. Utilizou-se o delineamento inteiramente casualizado (DIC), com 5 repetições. Transcorridos 75 dias do plantio as mudas foram avaliadas considerando-se a parte aérea e o sistema radicular. Observou-se efeito significativo nos tratamentos aplicados para a produção de mudas de pitaia. Os tratamentos contendo esterco bovino e suíno se apresentaram superiores com relação ao número de brotos, altura de plantas e matéria seca de brotos, o que os indica  proporcionar o melhor desenvolvimento de mudas de pitaia, em virtude dos acréscimos nutricionais e nas características físicas do substrato

Clinical Spectrum of West Nile Virus Neuroinvasive Disease.

West Nile virus (WNV) is the most common arbovirus infection in the United States. The diagnosis requires consideration of not only a broad spectrum of presenting symptoms, ranging from a mild febrile illness to severe encephalitis and acute flaccid paralysis, but also public health risk factors and seasonality. There is no approved targeted therapy for WNV, so treatment relies on supportive care, management of neurologic sequelae and airway, treatment of other systems including the eye, and aggressive rehabilitation. Here, we describe a series of 3 cases of WNV encountered in September 2018 at one institution. First, we describe a case of WNV encephalitis with worsened dyskinesias and a relatively good recovery. Second, we describe a severe WNV encephalitis with overlying motor neuron involvement with a poor outcome. Finally, we describe a case of a WNV meningitis with significant bilateral chorioretinitis, an underappreciated complication of WNV infections. Through these cases, we review the epidemiology of WNV, risk factors for infection, the neurologic sequalae and long-term outcomes, and the importance of recognizing ocular involvement to prevent ophthalmologic complications

Posterior reversible encephalopathy syndrome is not associated with mutations in aquaporin-4

Posterior reversible encephalopathy syndrome (PRES) is characterized by acute reversible subcortical vasogenic edema that is typically bilateral and self-limiting. It preferentially affects posterior regions of the brain. Clinical manifestations include encephalopathy, seizures, headache, and cortical blindness. PRES may be precipitated by hypertensive crises such as eclampsia and by immunosuppressive agents. The pathophysiology of PRES is incompletely understood. Disordered cerebral autoregulation leading to protein and fluid extravasation is thought to be important.1 Other theories implicate endothelial dysfunction or vasospasm.

O objetivo do presente estudo foi identificar os fatores de risco presentes na incidência de lesões desportivas (LD), entre 307 alunos da Faculdade de Educação Física da ACM de Sorocaba; especificamente visou-se explorar associações entre LD, modalidade e região corporal afetada. Trata-se de investigação observacional, transversal, considerando como variáveis independentes sexo, idade, índice de massa corporal (IMC), período de curso, fase do curso e modalidade, e, como dependentes, as referências de LD ocorridas no período de duas semanas. Os dados de interesse foram coletados através de inquérito de morbidade referida. No plano analítico, associações foram testadas pelo teste do qui-quadrado e realizou-se análise multivariada segundo ajuste de modelo logístico. Os principais resultados revelaram: 1) predominância significativa de LD nos membros inferiores (MMII); 2) associação entre estiramento e entorse nos MMII; 3) incidência maior de LD no primeiro semestre comparado com o sétimo; e 4) sexo, idade, período e IMC não se configuraram como fator risco para LD.<br>This study is aimed at identifying risk factors for sports injuries (SI) in 307 students of a Physical Education School in Sorocaba, SP. Associations were explored between SI, sports modality, and body region affected. Investigation was observational, cross-sectional, independent variables being gender, age, body mass index (BMI), school period, course stage and modality; reports of SI occurring in the last two weeks were taken as dependent variables. SI data were collected by means of a morbidity questionnaire. Profile analysis was performed by c² test and multivariate analysis by logistic modeling. Main results indicated: 1) significant predominance of SI in lower limbs; 2) associations between strain and sprain in lower limbs; 3) higher incidence of SI during the first semester of school as compared to the seventh semester, and 4) gender, age and BMI did not show influence as risk factors for SI

Effect of aqueous extracts of Brachiaria decumbens on the development of ornamental pepper

The use of natural plant growth promoters can be an effective, sustainable, and low-cost alternative to reduce input costs for the production of ornamental pepper. Thus, the objective of this study was to evaluate the effect of Brachiaria decumbens aqueous extract on the growth of ornamental pepper (Capsicum frutescens). The experiment was carried out in the Plant Nursery sector of the Federal Institute of Espirito Santo (IFES), located in the municipality of Santa Teresa, in the Serrana region of the Espirito Santo State (Brazil). The study was conducted using a randomized block design (RBD) with four replicates in a 4×2 factorial scheme with four doses of the Brachiaria decumbens extract (0, 50, 75 and 100%) and two application methods (edaphic application or foliar sprays). The number of days to flowering, plant height, leaf number, fruit number, leaf area, fruit, root, shoot, and total dry mass were determined. According to the results, the variables number of fruits and root dry mass had no significant effect on the interaction, with the best results found with the edaphic application when compared to the foliar sprays. When considering interaction, the application of 100% of the extract reduced the number of days to flowering for both edaphic application and foliar sprays. For growth variables, this same dose promoted the best results for most of the variables. Based on the results, the edaphic application of B. decumbens at 100% dosage is recommended to reduce the number of days to flowering and promote better development of ornamental pepper

Reuse of agricultural waste as an alternative substrate in the production of eggplant (Solanum melongena L.) seedlings

Seedling formation is one of the most important phases for the eggplant crop cycle. One of the decisive factors for obtaining quality seedlings and the consequent increase in productivity is the type of substrate used. The objective of this research was to evaluate the growth of eggplant seedlings grown in alternative substrates with increasing levels of “moinha” (residue from the coffee dry milling process) replacing the commercial substrate. The experiment was carried out in a completely randomized design, with six treatments and ten replicates. The treatments were: T1: commercial substrate (control); T2: 0% moinha (MO) + 40% burnt rice husk (BRH) + 15% coconut fiber (CF) + 5% eggshell (ES) + 40% commercial substrate (CS); T3: 10% MO + 40% BRH + 15% CF + 5% ES + 30% CS; T4: 20% MO + 40% BRH + 15% CF + 5% ES + 20% CS ; T5: 30% MO + 40% BRH + 15% CF + 5% ES + 10% CS; T6: 40% MO + 40% BRH + 15% CF + 5% ES + 0% CS. The electrical conductivity of the substrates and the seedling total dry mass, plant height and stem diameter were evaluated. It is recommended to use the substrate containing 20% MO + 40% BRH + 15% CF + 5% ES + 20% CS
