ABSTRACT Objective: This study aimed to evaluate whether the therapeutic use of caffeine for premature newborns is associated with changes in sleep habits and the presence of obstructive sleep apnea in childhood. Methods: This is a cross-sectional single-center study in which the caretakers of 87 children aged 5–10 years, born full-term or preterm, treated or not with caffeine in the neonatal period, answered questionnaires to screen for obstructive sleep apnea (Pediatric Obstructive Sleep Apnea Screening Tool [PosaST]) and to characterize the sleep habits (Children's Sleep Habits Questionnaire [CSHQ]) of their children. ANOVA and linear regression tests were performed to verify possible differences between the groups. Results: Children born prematurely who were treated with caffeine woke up significantly later on weekdays than those born at term (09h±00h58 and 07h43±1h15, respectively, p=0.022) and had longer total daily sleep time also compared to those born at term (10h24±1h08 and 09h29±1h08, respectively, p<0.001). There was no significant difference between the three groups in overall PosaST and CSHQ scores. Conclusions: Caffeine use in the neonatal period did not impair sleep habits later in life and did not lead to increased obstructive sleep apnea scores in prematurely born children compared to those born at term.

RESUMO Objetivo: Avaliar se o uso terapêutico de cafeína para recém-nascidos prematuros se associa a alterações nos hábitos de sono e à presença de apneia obstrutiva do sono na infância. Métodos: Este é um estudo unicêntrico transversal no qual os responsáveis por 87 crianças com idades entre cinco e dez anos, nascidas a termo ou pré-termo e tratadas ou não com cafeína no período neonatal responderam a questionários para triagem de apneia obstrutiva do sono (Pediatric Obstructive Sleep Apnea Screening Tool – PosaST) e para a caracterização dos hábitos de sono (Children's Sleep Habits Questionnaire – CSHQ) de seus filhos. Foram realizados testes de variância (ANOVA) e de regressão linear para verificar possíveis diferenças entre os grupos. Resultados: As crianças nascidas prematuras que foram tratadas com cafeína acordaram significativamente mais tarde nos dias de semana do que as nascidas a termo (09h±00h58 e 07h43±1h15, respectivamente, p=0,022) e tiveram maior tempo total de sono diário também comparadas às nascidas a termo (10h24±1h08 e 09h29±1h08, respectivamente, p<0,001). Não houve diferença significativa entre os três grupos na pontuação geral dos questionários PosaST e CSHQ. Conclusões: O uso de cafeína no período neonatal não prejudicou tardiamente os hábitos de sono e não levou ao aumento dos escores de apneia obstrutiva do sono de crianças nascidas prematuras quando comparadas com crianças nascidas a termo.

The main objective of this work was to develop and validate an analytical method using solid-liquid extraction and liquid chromatography coupled with mass spectrometry in tandem (LC-MS/MS) for the simultaneous determination of the herbicide 2-(2,4-dichlorophenoxy)acetic acid (2,4-D) and the insecticide fipronil and its degradation products, fipronil sulfone and fipronil sulfide in different types of soil from Brazil (Oxisol and Entisol). Solid-liquid extraction was performed in two cycles using 20 mL of dichloromethane per cycle and sonication. The extraction efficiency of 2,4-D was more influenced by soil composition than the other compounds. The limits of quantification of the method were between 0.015 and 0.75 mg kg-1 and recovery values from 61 to 118%, with a maximum relative standard deviation (RSD) value of 4%. The method was further applied to over 500 real soil and sediment samples. 2,4-D and fipronil concentrations varied from 0.03 to 1145 µg kg-1 and 1.1 to 282 µg kg-1, respectively.

ABSTRACT This experimental research aims to produce rice husk bio-concretes (RBCs) with a matrix of ternary mixtures of cement, rice husk ash and fly ash. The first step consisted in an evaluation of the influence of a superplasticizer additive and a polyfunctional additive on the rheological behavior of cementitious pastes. The purpose of this step was to test different levels of additives in order to develop a paste that, after adding high volumetric fractions of rice husk, allows obtaining RBCs that have adequate workability for compaction by mechanical vibration. A grinding and chemical treatment process was carried out on the rice husk to improve its adhesion with the matrix. The experimental results show that the PF type additive showed better compatibility with the ternary combination at an optimal content of 0.3%. Thus, the RBCs produced were cohesive, without segregation, with spreading of 210 ± 30 mm. The dry specific mass and compressive strength of the RBCs were determined after 28 days of age. Based on the results obtained, the BCCs presented specific mass between 1000 and 1300 kg/m3 and compressive strength higher than 8.0 MPa, indicating the possibility of use in the production of lightweight and load bearing panels.

RESUMO Esta pesquisa experimental tem como objetivo produzir bioconcretos de casca de arroz (BCCs) com uma matriz de misturas ternárias de cimento, cinza da casca de arroz e cinza volante. A primeira etapa consistiu na avaliação da influência de um aditivo superplastificante e um aditivo polifuncional no comportamento reológico de pastas cimentícias. O objetivo dessa etapa foi testar diferentes teores dos aditivos a fim de desenvolver uma pasta fluida que, após a adição de altas frações volumétricas de casca de arroz (CA), permita obter BCCs leves que possuam trabalhabilidade adequada para adensamento por vibração mecânica. Realizou-se uma trituração e um tratamento químico da CA, no intuito de melhorar sua aderência com a matriz. Os resultados experimentais mostram que o aditivo do tipo PF apresentou melhor compatibilidade com a matriz a um teor de 0,3%. Assim, os BCCs produzidos apresentaram-se coesos e sem segregação, com espalhamento de 210 ± 30 mm. A massa específica seca e a resistência à compressão foram determinadas aos 28 dias de idade. Com os resultados obtidos, os BCCs apresentaram massa específica entre 1000 e 1300 kg/m3 e resistência à compressão superiores a 8,0 MPa, indicando a possibilidade de utilização na produção de painéis leves e autoportantes.

Abstract Introduction: The association of diabetes with subclinical thyroid diseases may increase the risk of cardiovascular diseases. We analyzed the association of subclinical hypothyroidism, diabetes, and both diseases with carotid Intima-Media Thickness (cIMT) as a surrogate maker for early cardiovascular disease in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Methods: Cross-sectional analysis with data from the 3rd visit (2017‒2019). Linear regression models were used to evaluate the association of subclinical hypothyroidism, diabetes and of both diseases with a cIMT presented as Beta (95% Confidence Interval – 95% CI) without adjustment, with adjustment for sociodemographic variables (Model 1) and multivariable adjustment (Model 1 more cardiovascular risk factors). We also used logistic regression models to analyze the Odds Ratio (OR) and 95% CI for the association of both diseases using cIMT > P75%. Results: After the exclusion of patients with previous cardiovascular disease, 5,077 participants with no diseases, 1578 with diabetes, 662 with subclinical hypothyroidism, and 234 with both diseases were included in the analysis. Linear regression models showed an association of cIMT with only diabetes (β = 0.019; 95% CI 0.012 to 0.027; p < 0.0001) and subclinical hypothyroidism more diabetes (β = 0.03; 95% CI 0.010‒0.047, p < 0.0001). The logistic regression model reported an association between diabetes and CIMT higher than P75% (OR = 1.49, 95% CI 1.30‒1.71). No interaction between diabetes and subclinical hypothyroidism was detected using cIMT respectively as a continuous (p = 0.29) or as a categorical variable (p = 0.92). Discussion: Diabetes was associated with higher cIMT values. However, no additive effect of subclinical hypothyroidism associated with diabetes over cIMT was detected.

ABSTRACT Objective: To determine the relationship between psoriasis, thyroid-stimulating hormone (TSH), free thyroxine (FT4), free triodothyronine (FT3), thyroid peroxidase antibodies (TPOAb), and subclinical thyroid dysfunctions in middle-aged and older adults. Materials and methods: Cross-sectional analyses included a self-reported medical diagnosis of psoriasis and thyroid function from the 3rd visit (2017-2019) of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). TSH, FT4, and FT3 levels were analyzed as continuous variables and quintiles, and TPOAb positivity and subclinical hypothyroidism as a yes/no variable. Logistic regression models were built as crude and adjusted by main confounders (age, sex, education level, race/ethnicity, and smoking). Results: From 9,649 participants (52.3% women; 59.2 ± 8.7 years old), the prevalence of psoriasis was 2.8% (n = 270). TSH, FT4, TPOAb positivity, and subclinical hypothyroidism were not associated with psoriasis in the main analyses. In the stratified analysis, our findings showed positive associations of the lowest (OR = 2.01; 95% CI 1.05-3.84; p = 0.036) and the highest (OR = 2.13; 95% CI 1.12-4.05; p = 0.022) quintiles of FT4 and a protective association of TPOAb positivity (OR = 0.43; 95% CI 0.19-0.98; p = 0.046) with prevalent psoriasis in women. In the logistic regression for FT3, participants in the 1st quintile showed a statistically significant association with psoriasis for the whole sample (OR = 1.66; 95% CI 1.11-2.46; p = 0.013) and for men (OR = 2.25; 95% CI 1.25-4.04; p = 0.007) in the sex-stratified analysis. Conclusions: The present study showed that the association of FT4 levels with psoriasis are different according to sex, with a possible U-shaped curve in women but not in men. Although there were some associations of FT3 with psoriasis, they may be a consequence of non-thyroidal illness syndrome. Further prospective data may clarify the association of thyroid function and psoriasis.

Sugarcane is considered one of the greatest alternatives for the biofuels sector due to the high potential in the production of ethanol and its respective by-products. Processes of converting degraded pastures into sugarcane crops have been increasingly common in Brazil, as well as the use of pesticides to control plant diseases and pests in several crops. The objective of this work was to evaluate the occurrence of 2,4-D, ametryn, tebuthiuron, fipronil and its degradation products (fipronil sulfide and fipronil sulfone) in clay and sandy soils when applied to pasture and sugarcane management. Solid-liquid extraction and liquid chromatography coupled to mass spectrometry were used to quantify the compounds. The optimized method was validated with the following parameters: linear range from 0.5 to 300 µg L-1; linearity (r) > 0.99; precision with CV from 1.0 to 15.0%; accuracy of 60 to 117%, instrumental limit of detection (LOD) from 0.1 to 1.0 µg L-1 and instrumental limit of quantification (LOQ) of 0.5 µg L-1 for all pesticides, except 2,4-D (5.0 µg L-1). Pesticides concentrations of the experimental farms ranged from 0.1 to 266 µg kg-1, with the highest concentrations found in the months of pesticide’s application. The results showed the persistence of some pesticides in the soils even after months of use.

RESUMO Modelos de qualidade da água são frequentemente aplicados para apoiar as definições de planejamento e gestão de recursos hídricos. Este processo requer dados apropriados para calibrar e fazer o processo de verificação necessário para análise de validação. No entanto, em alguns estudos de caso, não há dados suficientes para executar um modelo complexo de qualidade da água, seja qual for o sistema de água, rio ou reservatório. No contexto de dados escassos, a busca por modelos simples de qualidade da água é uma alternativa para compreender o comportamento da qualidade da água. Nesta pesquisa, um modelo zero-dimensional não-permanente de qualidade de água foi desenvolvido e aplicado utilizando séries sintéticas de concentrações de fósforo para um reservatório brasileiro. Os resultados dos modelos zero-dimensionais desenvolvidos nesta pesquisa foram comparados aos resultados de um modelo tridimensional, a fim de verificar se esta metodologia pode ser uma alternativa mais simples ao modelo tridimensional complexo. Os resultados compatíveis dos modelos zero-dimensional (0D) e tridimensional (3D) mostram que os esquemas numéricos simplificados são importantes ferramentas potenciais a serem consideradas para a análise inicial da dinâmica da qualidade da água em reservatórios e para fins de gestão. hídricos validação entanto caso escassos zerodimensional zero dimensional nãopermanente permanente brasileiro zerodimensionais dimensionais 0D D (0D 3D (3D

ABSTRACT Water quality models are often applied to support the definitions for water resources planning and management. This process requires appropriate data to calibrate and make the required verification process for validation analysis. However, in some case studies, there is not enough data to run a complex water quality model whatever is the water system, being river or reservoir. In the context of scarce data, the search for a simple water quality model is an alternative to comprehend the water quality behavior of the water system. In this research, an unsteady zero-dimensional (0D) water quality model was developed and applied using synthetic series of phosphorus concentrations for a Brazilian reservoir. The results of the zero-dimensional models developed in this research were compared to the results of a three-dimensional water quality model, in order to verify if this methodology can be a simpler alternative to a complex three-dimensional model. The compatible results of the zero-dimensional (0D) and three-dimensional (3D) models show the simplified numerical schemes are important potential tools to be considered for initial analysis of water quality dynamics in reservoirs and for management purposes.

Abstract Aim: This study determined the energy expenditure and effort intensity of athletes during women's artistic gymnastics training sessions. Methods: Ten gymnasts (age 10.9 ± 1.7 years) performed a test to estimate the maximum rate of oxygen uptake (VO2max), during which the maximum heart rate (HRmax) was also obtained. The heart rate (HR) of these gymnasts was recorded during five training sessions and then used to estimate the exercise intensity and energy expenditure. Results: Mean duration of training sessions was 4.08 ± 0.42 h, with mean HR corresponding to 137 ± 8 bpm or 69.0 ± 3.5% of HRmax. Gymnasts spent less training time at 90-100% HRmax compared to the other HR ranges (p < 0.05). Time spent at 60-70% and 70-80% was higher compared to 80-90% HRmax (p = 0.012 and p = 0.001, respectively). The training impulse was 239.2 ± 35.4 AU. Estimated energy expenditure was 768.3 ± 168.5 kcal, metabolic rate was 3.1 ± 0.6 kcal/min, and the metabolic equivalent of task (MET) corresponded to 6.1 ± 0.6. Conclusion: Young gymnasts performed prolonged and moderate-intensity training sessions that generated high energetic demands. This information is beneficial to gymnasts since the coaching team can use the data to control the training load and prescribe a proper diet.

RESUMO Objetivos: descrever o clima organizacional percebido pelos enfermeiros de um hospital vinculado à Empresa Brasileira de Serviços Hospitalares e os motivos de intenção de rotatividade. Métodos: mistos, do tipo triangulação concomitante. Dados qualitativos analisados segundo o Discurso do Sujeito Coletivo; e dados quantitativos, análise descritiva, correlação de Pearson e regressão linear múltipla. A coleta de dados ocorreu mediante entrevista semiestruturada com 116 enfermeiros. Resultados: os discursos foram apresentados em cinco categorias: Apoio da chefia e organização; Recompensa; Conforto físico; Controle/pressão; e Coesão entre os colegas. Evidenciou-se que, com aumento do fator Recompensa, há uma diminuição da intenção de rotatividade; e, com a diminuição do Conforto físico, há um aumento da intenção de rotatividade. Conclusões: o clima organizacional percebido pelos enfermeiros encontra-se dicotomizado, e a intenção de rotatividade foi justificada, principalmente, por motivos pessoais. Acredita-se que isso decorra dos recentes processos de reorganização institucional e contratação de pessoal vivenciados.

ABSTRACT Objectives: to describe the organizational climate perceived by nurses of a hospital linked to the Brazilian Hospital Services Company and the reasons for the turnover intention. Methods: mixed, concomitant triangulation type. Qualitative data were analyzed according to the discourse of the collective subject, in addition to quantitative data analysis, descriptive analysis, Pearson correlation, and multiple linear regression. Data collection was carried through a semi-structured interview with 116 nurses. Results: the study presented the speeches in five categories: Leadership and organization support; Reward; Physical comfort; Control/pressure; and Cohesion among colleagues. It showed that, with increased Reward factor, there is a decrease in turnover intention; and, with decreased Physical comfort, there is an increase in turnover intention. Conclusions: there is a dichotomy in the organizational climate perceived by nurses, and personal reasons mainly justify the turnover intention. The reason could be the current processes of institutional reorganization and the hiring of experienced staff.

Abstract Objectives This analysis describes the protocol of a study with a case-cohort to design to prospectively evaluate the incidence of subclinical atherosclerosis and Cardiovascular Disease (CVD) in Chronic Inflammatory Disease (CID) participants compared to non-diseased ones. Methods A high-risk group for CID was defined based on data collected in all visits on self-reported medical diagnosis, use of medicines, and levels of high-sensitivity C-Reactive Protein >10 mg/L. The comparison group is the Aleatory Cohort Sample (ACS): a group with 10% of participants selected at baseline who represent the entire cohort. In both groups, specific biomarkers for DIC, markers of subclinical atherosclerosis, and CVD morbimortality will be tested using weighted Cox. Results The high-risk group (n = 2,949; aged 53.6 ± 9.2; 65.5% women) and the ACS (n=1543; 52.2±8.8; 54.1% women) were identified. Beyond being older and mostly women, participants in the high-risk group present low average income (29.1% vs. 24.8%, p < 0.0001), higher BMI (Kg/m2) (28.1 vs. 26.9, p < 0.0001), higher waist circumference (cm) (93.3 vs. 91, p < 0.0001), higher frequencies of hypertension (40.2% vs. 34.5%, p < 0.0001), diabetes (20.7% vs. 17%, p = 0.003) depression (5.8% vs. 3.9%, p = 0.007) and higher levels of GlycA a new inflammatory marker (p < 0.0001) compared to the ACS. Conclusions The high-risk group selected mostly women, older, lower-income/education, higher BMI, waist circumference, and of hypertension, diabetes, depression, and higher levels of GlycA when compared to the ACS. The strategy chosen to define the high-risk group seems adequate given that multiple sociodemographic and clinical characteristics are compatible with CID.

RESUMO Objetivo: verificar os fatores individuais, laborais e a região de atuação dos fonoaudiólogos atuantes no Brasil, com perfil em redes sociais e que as utilizam profissionalmente. Métodos: inquérito populacional via Web, realizado com fonoaudiólogos atuantes no Brasil no ano de 2020, por meio de um questionário on-line. O desfecho “Como você descreveria seu uso das mídias sociais?” foi recategorizado em “uso pessoal” e “uso profissional”. As frequências absolutas e relativas e análises multivariáveis ajustadas por Regressão de Poisson com variância robusta com seus respectivos intervalos de confiança de 95% são apresentados. Resultados: dos 442 entrevistados, 93,7% eram do sexo feminino, com média de idade de 38,0 anos (± 11,1). O desfecho “usar mídias sociais profissionalmente” foi encontrado em 64,7% dos entrevistados. Na análise multivariável, a relação de trabalho privada, idade entre 31 e 45 anos e mais de 26 anos de formação na graduação foram aspectos associados significantemente com o uso profissional das mídias sociais. Conclusão: aproximadamente dois terços dos fonoaudiólogos brasileiros com perfis em mídias sociais as utilizam profissionalmente, isso sugere a necessidade de reflexão e discussão sobre os caminhos desejáveis e aceitos em relação a adequada utilização destes meios para o trabalho.

ABSTRACT Purpose: to verify personal and work factors, and specialties of Brazilian speech-language therapists and audiologists who use social media profiles, professionally. Methods: an online questionnaire was used to carry out a population survey with working speech-language therapists and audiologists in Brazil, in 2020. The outcome of “How would you describe your use of social media?” was recategorized into “personal use” and “professional use”. Absolute and relative frequencies were calculated. Multivariate prevalence ratios were adjusted using the Poisson regression model with robust variance and 95% confidence intervals. Results: out of the 442 respondents, 93.7% were females, with a mean age of 38.0 years (± 11.1). The primary outcome, “professional use of social media”, occurred for 64.7% of the participants. In the multivariate analysis, private employment, participants in the 31-45 age range, and >26 years of work history after graduation were significantly associated with the professional use of social media. Conclusion: social media are used by approximately two-thirds of Brazilian speech-language therapists and audiologists. This finding suggests a need for reflection and discussion about the proper use of social media for work purposes.
