ABSTRACT Effluent from fish farming with saline water is a source of water, also rich in organic matter and nutrients, that can be used in irrigation of cultivated plants and even fully or partially replace mineral fertilization. The objective was to evaluate the growth, biomass production and quality of P. maximum cultivars fertigated with fish farming effluent in a greenhouse experiment, using a randomized block design with eight replicates. Treatments were arranged in a split-split-plot scheme, with three irrigation managements in the plot (irrigation with public-supply water, irrigation with public-supply water + conventional fertilization, and irrigation with fish farming effluent), three cultivars of P. maximum (Tanzania, Mombasa, and Massai) in the sub-plot, and four cutting times in the sub-sub-plot (45, 90, 135, and 180 days after sowing). Plant height, number of tillers, production of fresh biomass, neutral detergent fiber, acid detergent fiber, ether extract, crude protein, dry matter, and mineral matter contents were analyzed. The highest growth, production, and quality of P. maximum grass occurs when irrigated with public-supply water and under conventional NPK fertilization. Fertigation with fish farming effluent reduces the growth and production of P. maximum grass, but allows obtaining better quality forage. It is possible to irrigate P. maximum grass using fish farming effluent with satisfactory yields. The growth of cv. Massai was more sensitive to irrigation with fish farming effluent than those of the cultivars Tanzania and Mombasa. nutrients fertilization P experiment replicates splitsplitplot split scheme publicsupply public supply effluent, , effluent) Tanzania, (Tanzania Mombasa subplot, subplot sub plot, sub-plot subsubplot 45, 45 (45 90 135 18 sowing. sowing . sowing) height tillers fiber extract protein analyzed forage yields cv 4 (4 9 13 1 (

ABSTRACT Hemangiomas are benign congenital vascular tumors that commonly arise in the head and neck regions. Although they present with indolent growth and involution in most cases, they can cause facial deformities. Hemangiomas have three subtypes: capillary, cavernous, and mixed. The cavernous type is most commonly observed on the lateral wall of the nose or the inferior turbinate. This report describes a case of cavernous hemangioma diagnosed in a rare location in the left retromaxillary masticatory space in a 67-year-old woman. Total excision of the lesion was performed with surgical treatment through the Caldwell-Luc access. Anatomopathological and immunohistochemical examinations suggested a malformative vascular lesion with a cavernous hemangioma pattern and without signs of malignancy. regions cases deformities subtypes capillary mixed turbinate 67yearold yearold 67 year old woman CaldwellLuc Caldwell Luc access malignancy 6

Abstract Background: Tele-cardiology tools are valuable strategies to improve risk stratification. Objective: We aimed to evaluate the accuracy of tele-electrocardiography (ECG) to predict abnormalities in screening echocardiography (echo) in primary care (PC). Methods: In 17 months, 6 health providers at 16 PC units were trained on simplified handheld echo protocols. Tele-ECGs were recorded for final diagnosis by a cardiologist. Consented patients with major ECG abnormalities by the Minnesota code, and a 1:5 sample of normal individuals underwent clinical questionnaire and screening echo interpreted remotely. Major heart disease was defined as moderate/severe valve disease, ventricular dysfunction/hypertrophy, pericardial effusion, or wall-motion abnormalities. Association between major ECG and echo abnormalities was assessed by logistic regression as follows: 1) unadjusted model; 2) model 1 adjusted for age/sex; 3) model 2 plus risk factors (hypertension/diabetes); 4) model 3 plus history of cardiovascular disease (Chagas/rheumatic heart disease/ischemic heart disease/stroke/heart failure). P-values < 0.05 were considered significant. Results: A total 1,411 patients underwent echo; 1,149 (81%) had major ECG abnormalities. Median age was 67 (IQR 60 to 74) years, and 51.4% were male. Major ECG abnormalities were associated with a 2.4-fold chance of major heart disease on echo in bivariate analysis (OR = 2.42 [95% CI 1.76 to 3.39]), and remained significant after adjustments in models (p < 0.001) 2 (OR = 2.57 [95% CI 1.84 to 3.65]), model 3 (OR = 2.52 [95% CI 1.80 to3.58]), and model 4 (OR = 2.23 [95%CI 1.59 to 3.19]). Age, male sex, heart failure, and ischemic heart disease were also independent predictors of major heart disease on echo. Conclusions: Tele-ECG abnormalities increased the likelihood of major heart disease on screening echo, even after adjustments for demographic and clinical variables.

Resumo Fundamento: As ferramentas de telecardiologia são estratégias valiosas para melhorar a estratificação de risco. Objetivo: Objetivamos avaliar a acurácia da tele-eletrocardiografia (ECG) para predizer anormalidades no ecocardiograma de rastreamento na atenção primária. Métodos: Em 17 meses, 6 profissionais de saúde em 16 unidades de atenção primária foram treinados em protocolos simplificados de ecocardiografia portátil. Tele-ECGs foram registrados para diagnóstico final por um cardiologista. Pacientes consentidos com anormalidades maiores no ECG pelo código de Minnesota e uma amostra 1:5 de indivíduos normais foram submetidos a um questionário clínico e ecocardiograma de rastreamento interpretado remotamente. A doença cardíaca grave foi definida como doença valvular moderada/grave, disfunção/hipertrofia ventricular, derrame pericárdico ou anormalidade da motilidade. A associação entre alterações maiores do ECG e anormalidades ecocardiográficas foi avaliada por regressão logística da seguinte forma: 1) modelo não ajustado; 2) modelo 1 ajustado por idade/sexo; 3) modelo 2 mais fatores de risco (hipertensão/diabetes); 4) modelo 3 mais história de doença cardiovascular (Chagas/cardiopatia reumática/cardiopatia isquêmica/AVC/insuficiência cardíaca). Foram considerados significativos valores de p < 0,05. Resultados: No total, 1.411 pacientes realizaram ecocardiograma, sendo 1.149 (81%) com anormalidades maiores no ECG. A idade mediana foi de 67 anos (intervalo interquartil de 60 a 74) e 51,4% eram do sexo masculino. As anormalidades maiores no ECG se associaram a uma chance 2,4 vezes maior de doença cardíaca grave no ecocardiograma de rastreamento na análise bivariada (OR = 2,42 [IC 95% 1,76 a 3,39]) e permaneceram significativas (p < 0,001) após ajustes no modelo 2 (OR = 2,57 [IC 95% 1,84 a 3,65]), modelo 3 (OR = 2,52 [IC 95% 1,80 a 3,58]) e modelo 4 (OR = 2,23 [IC 95% 1,59 a 3,19]). Idade, sexo masculino, insuficiência cardíaca e doença cardíaca isquêmica também foram preditores independentes de doença cardíaca grave no ecocardiograma. Conclusões: As anormalidades do tele-ECG aumentaram a probabilidade de doença cardíaca grave no ecocardiograma de rastreamento, mesmo após ajustes para variáveis demográficas e clínicas.

Abstract Objective To evaluate clinical characteristics and outcomes of COVID-19 patients infected with HIV, and to compare with a paired sample without HIV infection. Methods This is a substudy of a Brazilian multicentric cohort that comprised two periods (2020 and 2021). Data was obtained through the retrospective review of medical records. Primary outcomes were admission to the intensive care unit, invasive mechanical ventilation, and death. Patients with HIV and controls were matched for age, sex, number of comorbidities, and hospital of origin using the technique of propensity score matching (up to 4:1). They were compared using the Chi-Square or Fisher's Exact tests for categorical variables and the Wilcoxon for numerical variables. Results Throughout the study, 17,101 COVID-19 patients were hospitalized, and 130 (0.76%) of those were infected with HIV. The median age was 54 (IQR: 43.0;64.0) years in 2020 and 53 (IQR: 46.0;63.5) years in 2021, with a predominance of females in both periods. People Living with HIV (PLHIV) and their controls showed similar prevalence for admission to the ICU and invasive mechanical ventilation requirement in the two periods, with no significant differences. In 2020, in-hospital mortality was higher in the PLHIV compared to the controls (27.9% vs. 17.7%; p = 0.049), but there was no difference in mortality between groups in 2021 (25.0% vs. 25.1%; p > 0.999). Conclusions Our results reiterate that PLHIV were at higher risk of COVID-19 mortality in the early stages of the pandemic, however, this finding did not sustain in 2021, when the mortality rate is similar to the control group.

ABSTRACT Objective: To analyze the prevalence and factors associated with the lifestyle profile of public basic education teachers in Minas Gerais during the COVID-19 pandemic. Method: Epidemiological websurvey carried out with public basic education teachers in Minas Gerais. Data collection took place from August to September2020 via digital form. Anthropometric, sociodemographic, work, and lifestyle characteristics were evaluated. Poisson Regression was used. Results: 15,641 teachers participated and 31.1% had inadequate health habits. There was a higher prevalence among men (PR=1.38; 95%CI:1.31;1.45), older age (PR=1.20; 95%CI: 1.07;1.34), greater weekly workload (RP=1.10; 95%CI:1.03;1.17) and those dissatisfied with work (RP=1.21; 95%CI:1.15;1.27). As a protective factor, professors with longer teaching experience (RP=0.92; 95%CI:0.87;0.98) and those hired or appointed (PR=0.89; 95%CI:0.85) ;0.94). Conclusion: Lifestyle inadequacy was found among older male teachers, with longer working hours and job dissatisfaction.

Abstract Leptophlebiidae is the second most diverse family within Ephemeroptera, with species distributed across various States in Brazil, but with gaps in distribution records in others. Currently, nine species of Leptophlebiidae are recorded for the state of Piauí. Based on this information gap, the objective of this study was to present an updated species list of the family Leptophlebiidae new occurrence records and distributional sites for the state of Piauí, Brazil. By analyzing 447 specimens, we have significantly expanded our knowledge about the distribution of Leptophlebiidae species in the state of Piauí, increasing the recorded species from nine to 17. We have also added new occurrence records for six species and, for the first time, documented the presence of four genera. It is important to highlight that there is still an extensive area within the Cerrado and Brazilian semiarid regions where the occurrence of Ephemeroptera is unknown, confirming that the diversity in this area is underestimated and that knowledge of Ephemeroptera species and their distributions can expand with increased sampling efforts in the coming years, reducing the Linnean and Wallacean shortfall regarding this group. Our results also demonstrate the urgent need for inventories in the southern part of the state of Piauí, particularly in the sub-basins of the middle and upper Parnaíba river, which are considered suitable for monoculture expansion in Brazil.

Resumo Leptophlebiidae é a segunda família mais diversa de Ephemeroptera, com espécies distribuídas em vários estados do Brasil, mas com lacunas no registro de distribuição em outros. Por exemplo, no estado do Piauí tem registrado apenas nove espécies de Leptophlebiidae. Baseada nessa lacuna de informação, o objetivo deste estudo foi apresentar uma lista atualizada de espécies da família Leptophlebiidae, novos registros de ocorrência e sítios de distribuição para o estado do Piauí, Brasil. Ao analisar 447 exemplares, ampliamos significativamente nosso conhecimento sobre a distribuição das espécies de Leptophlebiidae no estado do Piauí, aumentando o número de espécies registradas de nove para 17. Também adicionamos novos registros de ocorrência para seis espécies e, pela primeira vez, documentamos a presença de quatro gêneros. Destacamos que ainda existe uma extensa área do Cerrado e semiárido brasileiro que se desconhece a ocorrência de Ephemeroptera, confirmando que a diversidade nessa área é subestimada e que o conhecimento sobre as espécies de Ephemeroptera e suas distribuições podem se expandir com o aumento do esforço amostral nos próximos anos, diminuindo as lacunas Lineana e Wallaceana sobre esse grupo. Nossos resultados também demonstram a necessidade emergencial de inventários no sul do Estado do Piauí, principalmente nas sub-bacias do médio e alto rio Parnaíba que é considerado adequado para a expansão da monocultura no Brasil.

ABSTRACT Water scarcity is one of the main problems in the Semiarid region of Brazil, which can be mitigated by water resource management strategies. The objective of this work was to classify waters of a watershed in the Semiarid region of Brazil and select the water attributes that most affect the quality of waters used for irrigation (QWI), using multivariate statistics. The study area was the Riacho da Bica watershed, which is between the municipalities of Portalegre and Viçosa, Rio Grande do Norte, Brazil. The QWI was determined using water samples from 15 collections carried out from 2016 to 2018, in five specific points of the watershed, starting in the spring and following the water course. The water attributes evaluated were: electrical conductivity (EC), potential hydrogen (pH), and sodium (Na+), potassium (K+), magnesium (Mg2+), calcium (Ca2+), carbonate (CO32-), chloride (Cl-), and bicarbonate (HCO3-) contents. The water quality data were subjected to multivariate statistics through factorial analysis (FA) and principal component analysis (PCA). The application of multivariate statistics through FA-PCA generated four principal components. The attributes that most explained the QWI variation were potassium, calcium, and pH for Factor 01, and sodium and RAS for Factor 02. The watershed waters were classified as low risk of salinity and medium risk of sodicity (C1S2) for irrigation purposes.

RESUMO A escassez hídrica se configura como um dos principais problemas do semiárido, devendo ser mitigado pelas estratégias de gestão dos recursos hídricos. O objetivo desse trabalho foi classificar a água e utilizar a estatística multivariada, como uma ferramenta para selecionar os atributos que possuem maior influência na qualidade da água utilizada para fins de irrigação, em uma microbacia hidrográfica do semiárido brasileiro. Á área de estudo está inserida na microbacia hidrográfica do Riacho da Bica, entre os municípios de Portalegre-RN e Viçosa-RN. A determinação da qualidade da água para fins de irrigação foi realizada por meio de quinze campanhas de coleta de amostras de água em cinco pontos específicos do Riacho da Bica, iniciando na nascente e seguindo o curso d’água, no período de 2016 a 2018, sendo avaliados atributos como condutividade elétrica (CE), potencial hidrogeniônico (pH), sódio (Na+), potássio (K+), magnésio (Mg2+), cálcio (Ca2+), carbonato (CO32-), cloreto (Cl-), bicarbonato (HCO3-). Os dados de qualidade de água foram submetidos a estatística multivariada com a realização da análise fatorial (AF) e a análise de componentes principais (ACP). A aplicação da estatística multivariada, gerou através da ACP/AF, quatro componentes principais. O pH, potássio e cálcio foram os atributos que mais explicam a qualidade da água para irrigação para o Fator 01, para o Fator 02 os atributos sódio e RAS. A água da microbacia hidrográfica foi classificada para fins de irrigação como baixo risco de salinidade e médio risco de sodicidade (C1S2).

RESUMEN Este estudio tuvo como objetivo evaluar el crecimiento, producción y nutrición de algodón de color natural (cultivar BRS Verde) regado con agua salina en diferentes etapas de crecimiento. El ensayo se realizó en un diseño de bloques al azar en el que los tratamientos consistieron en tres niveles de salinidad del agua de riego aplicados a lo largo del ciclo del cultivo o alternativamente en tres etapas de crecimiento. El agua de menor salinidad se extrajo del acuífero Arenito Açu en el estado de Rio Grande do Norte, Brasil; el agua de mayor salinidad se preparó para obtener una salinidad similar a la del agua extraída del acuífero Calcário Jandaíra, y la salinidad intermedia se obtuvo de la mezcla de volúmenes iguales de las aguas de menor y mayor salinidad. Se recomienda la aplicación de agua de menor salinidad en todas las etapas de crecimiento debido a los incrementos de aproximadamente 19% en el crecimiento del algodón y 40% en el rendimiento comparado con la aplicación de agua de intermedia o mayor salinidad. La aplicación de agua de menor salinidad en la etapa vegetativa y de agua de salinidad intermedia en las siguientes etapas es una alternativa al uso de agua de buena calidad durante todo el ciclo, a pesar de las disminuciones de alrededor de 7% en el crecimiento y 16% en el rendimiento. La nutrición de las plantas de algodón regadas con agua salina durante todo el ciclo o en algunas etapas de crecimiento estuvo marcada por un aumento de hasta un 86% en el contenido de sodio de la hoja de algodón, una disminución del contenido de potasio de la hoja de hasta un 21% y aumentos entre un 24 y 188% en el contenido de micronutrientes de las hojas cuando el agua de mayor salinidad reemplazó a la de menor salinidad.

ABSTRACT This study aimed to evaluate the growth, production, and nutrition of naturally colored cotton (cultivar BRS Verde) irrigated with saline water in different growth stages. The trial was conducted with a randomized block design in which the treatments consisted of three irrigation water salinity levels applied throughout the crop cycle or alternately in three growth stages. The lowest-salinity water was drawn from the Arenito Açu aquifer in the state of Rio Grande do Norte, Brazil; the highest-salinity water was prepared to obtain salinity similar to the water drawn from the Calcário Jandaíra aquifer, and an intermediate salinity was obtained from the mixture of equal volumes of the lowest and highest-salinity waters. The application of the lowest-salinity water is recommended in all growth stages due to the increases of about 19% in cotton growth and 40% in yield compared to the application of intermediate or highest-salinity water. The application of the lowest-salinity water in the vegetative stage and the intermediate-salinity water in the following stages is an alternative to using good quality water throughout the cycle, despite the decreases of about 7% in growth and 16% in yield. The nutrition of cotton plants irrigated with saline water throughout the cycle or in some growth stages was marked by an increase of up to 86% in the cotton leaf sodium content, a decrease in the leaf potassium content of up to 21% and increases between 24% and 188% in leaf micronutrient content when the highest-salinity water replaced that with the lowest salinity.

Resumo Investigou-se a associação entre o consumo de álcool pelos escolares com os conflitos familiares, supervisão dos pais e qualidade dos relacionamentos. Estudo transversal realizado com 1.265 adolescentes de 21 escolas. Foi utilizada a versão brasileira do Inventário de Triagem do Uso de Drogas/DUSI e estimadas prevalências absolutas e relativas para variáveis categóricas, e conduzidas análises bivariadas: teste Qui Quadrado de Pearson. Para magnitude da associação entre a variável dependente e independentes foram estimadas razões de prevalências por meio deregressão multivariável de Poisson. Houve associação do consumo de álcool com uso de drogas por familiares, discussões frequentes e desconhecimento dos pais sobre o que os adolescentes fazem. Supervisão familiar, bom relacionamento com pais/responsáveis, estabelecimento de vínculo familiar afetivo e ciência dos pais acerca do que os adolescentes fazem e onde estão, foram fatores de proteção para uso de álcool. Concluiu-se que a alta taxa de escolares que consomem álcool é preocupante, passível de complicações da saúde na sua integralidade, sendo fundamental relação familiar harmonizada. A implementação de práticas interventivas entre escola e Estratégia de Saúde da Família, podem contribuir no estabelecimento de vínculo protetivo.

Abstract The association between alcohol consumption by students with family conflicts, parental supervision and quality of relationships was investigated. A cross-sectional study was conducted with 1,265 adolescents from 21 schools. The Brazilian version of the Drug Use Screening Inventory/DUSI was used, and absolute and relative prevalence for categorical variables was estimated, while bivariate analyses and Pearson’s Chi Square test were conducted. For the magnitude of the association between the dependent and independent variables, prevalence ratios were estimated using Poisson multivariate regression. There was an association between alcohol consumption and drug use by family members, frequent discussions and parental lack of awareness about adolescents’ activities. Family supervision, a good relationship with parents/guardians, establishing an affective family bond and parents’ knowledge about teenagers’ whereabouts, were protective factors for alcohol use. The conclusion was that the high rate of schoolchildren who consume alcohol is worrying, liable to health complications in general, and a harmonized family relationship is fundamental. The implementation of measures of intervention between school and the Family Health Strategy, can contribute to the establishment of a protective bond.
