Abstract Background: Real-world, primary data on the treatment of psoriasis are scarce, especially concerning the role of soluble biomarkers as outcome predictors. Objective: The authors evaluated the utility of Th1/Th17 serum cytokines along with clinical characteristics as predictors of drug survival in the treatment of psoriasis. Methods: The authors consecutively included participants with moderate to severe psoriasis who were followed up for 6 years. Baseline interferon-α, tumor necrosis factor-α, and inter-leukin (IL)-2, IL-4, IL-6, IL-10, and IL-17A were measured using a cytometric bead array; clinical data were assessed. The authors calculated hazard ratios (HRs) for drug survival using a Cox proportional hazards model. Results: The authors included 262 patients, most of whom used systemic immunosuppressants or biologics. In the multivariate model, poor quality of life measured by the Dermatology Life Quality Index (HR = 1.04; 95% CI 1.01–1.07; p = 0.012) and elevated baseline IL-6 (HR = 1.99; 95% CI 1.29–3.08; p = 0.002) were associated with treatment interruption. Study limitations: The main limitation of any cohort study is the presence of confounders that could not be detected in clinical evaluation. Conclusions: Poor quality of life and elevated baseline serum IL-6 level predicted treatment interruption in patients with moderate to severe psoriasis. Although IL-6 is not the most important mediator of the inflammatory pathway in the skin environment, it is an interesting biomarker candidate for predicting psoriasis treatment response.

ABSTRACT Wild birds have great prominence in the transmission of diseases to humans, mainly due to their ease of access to human populations, raising concerns about the potential impact of that proximity on public health. The present study reports ARV and PBV occurrence in wild birds from an environmental protection area in the Amazon biome, in Pará state, Brazil. We obtained 155 fecal specimens from 47 species of wild birds for RNA extraction, ARV and PBV detection utilizing molecular methods, nucleotide sequencing, and phylogenetic analysis. ARV prevalence was 0.6% (1/155), being positive in an individual of Myrmotherula longipennis, and PBV prevalence was 1.29% (2/155), affecting two individuals of Guira guira. The PBV strains were assigned to genogroup I based on phylogenetic analysis, and they shared a strong phylogenetic link with strains isolated from different geographic locations. The ARV strain was more closely related to strains that had previously circulated in the same region. The presence of ARV and PBV in this habitat suggests that infection cycles of these agents occur naturally in the wild ecosystem, potentially triggering transmission events between bird species and humans. This is the first study on ARV detection in wild birds in Brazil and the first report on the occurrence of PBV in wild Guira guira. Additional studies are required to determine the epidemiology, origin, evolution, and emergence of new potentially pathogenic viruses in the Amazon.

RESUMO As aves silvestres têm grande destaque na transmissão de doenças ao homem, principalmente pela facilidade de acesso à população humana, levantando preocupações sobre o potencial impacto dessa proximidade no contexto da saúde pública. O presente estudo relata a ocorrência de ARV e PBV em aves silvestres de uma área de proteção ambiental no bioma Amazônico. Obtivemos 155 espécimes fecais de 47 espécies de aves silvestres, que foram submetidos a extração de RNA, detecção de ARV e PBV por técnicas moleculares, sequenciamento nucleotídico e análise filogenética. A prevalência de infecção por ARV foi 0,6% (1/155), sendo positivo em um indivíduo de Myrmotherula longipennis, e a prevalência de PBV foi 1,29% (2/155), afetando dois insdivíduos de Guira guira. A análise filogenética agrupou as cepas de PBV no genogrupo I, mostrando intensa relação filogenética com cepas isoladas de outras regiões geográficas. A cepa de ARV esteve mais relacionada filogeneticamente a cepas previamente circulantes na mesma região. Este é o primeiro estudo sobre detecção de ARV em aves silvestres no Brasil e o primeiro relato sobre a ocorrência de PBV em Guira guira. A circulação de ARV e PBV nesse ambiente demonstra que os ciclos desses agentes estão ocorrendo de forma natural no ecossistema silvestre, o que pode desencadear possíveis eventos de transmissão entre as espécies aviárias e humanos. Estudos adicionais são necessários para determinar a epidemiologia, origem, evolução e surgimento de novos vírus potencialmente patogênicos na Amazônia.

Abstract Large quantities of residual cooking oil are being increasingly generated in various sectors, as it is often improperly disposed of and causes serious environmental problems. A commonly used alternative is the use of lipases in enzymatic hydrolysis, since it is rather attractive to several sectors, in addition to allowing the use of products generated thereof, such as: free fatty acids, diacylglycerols, monoacylglycerols and free glycerol, moreover, it is capable of operating in mild temperature and pressure conditions. Therefore, the present study aimed to evaluate alternatives for the hydrolysis of residual frying oil by evaluating the efficiency of different types of supports and heating systems using free and immobilized forms of lipase from Burkholderia cepacia (BCL) and Porcine pancreas (PPL) as biocatalyst. Polyhydroxybutyrate (PHB), niobium oxide (Nb2O5) and chitosan (CHIT) were evaluated as support for immobilizing BCL and PPL lipases, and superior results were found regarding the hydrolytic activity of immobilization derivatives using PHB and Nb2O5. Among the heating systems under evaluation, the highest percentage of residual oil hydrolysis was found using the ultrasound system for both free and immobilized lipases, reaching 57.91% hydrolysis for lipases immobilized on Nb2O5 and 61.11% hydrolysis for the derivative immobilized on PHB. The operational stability of both biocatalysts was evaluated using similar half-life time values for both. Thus, it was observed that the ultrasound system was efficient in improving lipase performance in the hydrolysis of free fatty acids, once this unconventional heating system is quite promising for accelerating such enzymatic reactions.

ABSTRACT BACKGROUND: Specific types of violence such as intimate partner sexual violence and intimate partner homicide occur more frequently in rural areas. OBJECTIVE: This study aimed to systematically review the literature on the knowledge and attitudes of rural healthcare providers regarding cases of domestic violence against women. DESIGN AND SETTING: Systematic review developed at Universidade Federal de Uberlândia. METHODS: We conducted an electronic search of six databases, which only included observational studies, regardless of the year, language, or country of publication, except for studies that used secondary data and were exclusively qualitative. Two reviewers performed the selection, data extraction, and risk of bias assessment using a specific Joanna Briggs Institute tool. RESULTS: Six studies met the inclusion criteria. All the studies had a low risk of bias. Approximately 38% of these professionals identified injuries caused by violence in patients. When asked about knowing the correct attitude to take in cases of confirmed violence, between 12% and 64% of rural healthcare providers answered positively; most of them would refer to specialized institutions and promote victim empowerment and counseling. The number of professionals with an educational background in the field ranged from 16% to 98%. CONCLUSIONS: The evident disparity across studies shows that some professionals have suboptimal knowledge and require training to adopt the correct attitude when identifying female victims of domestic violence in clinical practice. SYSTEMATIC REVIEW REGISTRATION: This systematic review was registered in the Open Science Framework Database under the registration http://doi.org/10.17605/OSF.IO/B7Q6S.

ABSTRACT The aim of this article is to identify organizational strategies and operational challenges to implement the multidisciplinary work process of the Expanded Family Health and Primary Healthcare Center (NASF-AB) teams in the context of the COVID-19 pandemic in Brazil. This is an integrative review study in the LILACS and Science Direct databases, PubMed, Virtual Health Library (VHL), Scientific Electronic Library Online (SciELO), Google Scholar and document review of technical publications (protocols, technical notes, letters, ordinances) on the official website of the Brazilian Ministry of Health. Thirteen studies were included and no technical documents published by the Ministry of Health were located which dealt directly with the reorganization of the NASF-AB work process during the pandemic. It was evidenced that the elements that make up the teamwork process have been modified, such as interprofessional communication and collaboration, interdependence of actions and user-centered care. During the course of the pandemic, a predominance of managerial rationality was noted, with a greater focus on case screening and monitoring activities and clinical-assistance support to the detriment of technical-pedagogical support to Primary Care (PC) teams, characterizing an underutilization of the potential of the multiprofessional team within the scope of Primary Health Care.

RESUMO O objetivo deste artigo é identificar as estratégias para organização e os desafios operacionais para efetivar o processo de trabalho multiprofissional das equipes do Núcleo Ampliado de Saúde da Família e Atenção Básica (Nasf-AB) no contexto da pandemia da Covid-19 no Brasil. Trata-se de estudo de revisão integrativa nas bases de dados Lilacs, Science Direct, PubMed, Biblioteca Virtual em Saúde (BVS), Scientific Electronic Library Online (SciELO), Scholar Google e revisão documental de publicações técnicas (protocolos, notas técnicas, ofícios, portarias) no site oficial do Ministério da Saúde do Brasil. Foram incluídos 13 estudos e não foram localizados documentos técnicos publicados pelo Ministério da Saúde que tratassem diretamente sobre a reorganização do processo de trabalho do Nasf-AB durante a pandemia. Evidenciou-se que os elementos que compõem o processo de trabalho em equipe foram modificados, tais como comunicação e colaboração interprofissional, interdependência das ações e atenção centrada no usuário. No curso da pandemia, notou-se uma predominância da racionalidade gerencial, com maior foco em atividades de rastreio e monitoramento de casos e apoio clínico-assistencial, em detrimento de apoio técnico-pedagógico às equipes de AB, caracterizando um subaproveitamento das potencialidades da equipe multiprofissional no âmbito da Atenção Primária à Saúde.

Abstract Introduction: recent studies have suggested the use of neck circumference as a parameter capable of identifying risks of cardiometabolic complications and the accumulation of truncal fat caused by both antiretroviral therapy and the lifestyle of people with the human immunodeficiency virus (HIV). Objective: to investigate the relationship between neck circumference and anthropometric indicators and to assess cardiometabolic risk and truncal obesity through proposed cut-off points. Methods: cross-sectional study including 233 people with HIV. Demographic, socioeconomic, lifestyle and clinical data were collected using a structured questionnaire. The anthropometric evaluation included: weight, height, body mass index (BMI) measurements; waist (WC), neck (NC), arm and arm muscle circumferences; triceps and subscapular skinfolds and their sum. ROC curves were constructed to determine the accuracy of NC in predicting cardiometabolic risk in people living with HIV. Results: the sample was 57.5 % male, with a mean age of 38.4 years (95 % CI: 37.2-39.7 years). NC showed a positive and significant correlation with all anthropometric variables analyzed (p < 0.05), and a higher correlation strength with WC and BMI. The NC cut-off point selected as a predictor of risk of cardiac metabolic complications and truncal obesity in women was ≥ 32.4 cm, considering both WC and BMI. For men, the NC cut-off points were different when considering WC (≥ 39.6 cm) and BMI (≥ 38.1 cm) as a reference. It is worth noting that NC performed well in ROC curve analysis for men, while in women it was a poor performance. Conclusion: NC proved to be a promising indicator in the assessment of nutrition and health of people living with HIV, especially in men.

Resumen Introducción: estudios recientes han sugerido el uso de la circunferencia del cuello como parámetro capaz de identificar los riesgos de complicaciones cardiometabólicas y la acumulación de grasa troncal causados tanto por la terapia antirretroviral como por el estilo de vida de las personas con el virus de la inmunodeficiencia humana (VIH). Objetivo: investigar la relación entre la circunferencia del cuello y los indicadores antropométricos y evaluar el riesgo cardiometabólico y la obesidad troncal a través de los puntos de corte propuestos. Métodos: estudio transversal que incluyó a 233 personas con VIH. Se recogieron datos demográficos, socioeconómicos, de estilo de vida y clínicos mediante un cuestionario estructurado. La evaluación antropométrica incluyó: medidas de peso, altura, índice de masa corporal (IMC); circunferencias de cintura (CC), cuello (CN), brazo (CA) y músculo del brazo (MCB); pliegues cutáneos del tríceps y subescapular y su suma. Se construyeron curvas ROC para determinar la precisión de la CN en la predicción del riesgo cardiometabólico en personas que viven con el VIH. Resultados: el 57,5 % de la muestra eran varones, con una edad media de 38,4 años (IC 95 %: 37,2-39,7 años). La CN mostró una correlación positiva y significativa (p < 0,05) con todas las variables antropométricas analizadas, y una mayor fuerza de correlación con la CC y el IMC. El punto de corte de la CN seleccionado como predictor de riesgo de complicaciones metabólicas cardiacas y obesidad troncular en mujeres fue ≥ 32,4 cm, considerando tanto la CC como el IMC. En el caso de los hombres, los puntos de corte de la CN fueron diferentes al considerar como referencia la CC (≥ 39,6 cm) y el IMC (≥ 38,1 cm). Cabe destacar que la CN obtuvo buenos resultados en el análisis de la curva ROC en el caso de los hombres, mientras que en el de las mujeres fue deficiente. Conclusión: la CN demostró ser un indicador prometedor en la evaluación de la nutrición y la salud de las personas que viven con el VIH, especialmente en los hombres.

RESUMO O objetivo desse estudo foi comparar os efeitos do treinamento funcional (TF) orientado à velocidade (VOTF) e orientado à força (SOTF) em diferentes parâmetros de corrida de mudança de direção (COD), capacidade de salto e velocidade linear em jogadores de futebol sub-20. Para isso, 22 jogadores foram randomizados em dois grupos: VOFT e SOFT. Os participantes foram avaliados no momento pré e no momento pós-intervenção no teste de corrida em L para o lado direito (CODLD) e para o lado esquerdo (CODLE) para avaliar o COD veloz (≤ 90°) e no teste de ziguezague para avaliar o COD força (> 90°). Altura de salto foi aferida pelo salto com contramovimento (CMJ) e pelo salto de agachamento (SJ). A velocidade máxima foi avaliada pelo teste de sprint em 20 metros. O índice de déficit de mudança de direção (COD déficit) foi calculado para todos os testes de COD. Ambos os grupos apresentaram melhora significativa ao longo do tempo no CODLD, no ziguezague teste, no COD déficit de CODLD e no COD déficit do ziguezague. O teste de sprint em 20 metros, o CODLE e o COD déficit de CODLE não diferiram significativamente para nenhum grupo em nenhum momento. Apesar de não apresentar diferença estatisticamente significativa ao longo do tempo, o CMJ apresentou tamanho de efeito pequeno para o VOFT e SOFT. Enquanto o SJ apresentou tamanho de efeito moderado para o VOFT e pequeno para o SOFT. Além disso, não houve diferença significativa entre grupos para nenhuma variável. Portanto conclui-se que a aplicação de protocolos de TF orientados para velocidade ou força como forma complementar ao treinamento técnico tático, ao longo de quatro semanas, promove mudanças significativas em diferentes parâmetros de corrida COD em atletas de futebol sub-20.

ABSTRACT The aim of this study was to compare the effects of velocity-oriented (VOTF) and strength-oriented (SOTF) functional training (TF) on different parameters of running change of direction (COD), jumping ability and linear velocity in under-20 soccer players. For this, 22 players were randomly assigned to VOFT and SOFT groups. The participants were evaluated at the pre- and post-intervention moment in the L-running test to the right side (CODLD) and to the left side (CODLE) to evaluate the fast COD (≤ 90°) and in the zigzag test to evaluate the strength COD (> 90°). Jump height was measured by countermovement jump (CMJ) and squat jump (SJ). Maximum speed was assessed by the 20-meter sprint test. The change of direction deficit index (COD deficit) was calculated for all COD tests. Both groups showed significant improvement over time in CODLD, zigzag test, COD-deficit CODLD, and COD zigzag deficit. The 20-meter sprint test, CODLE, and COD-deficit CODLE did not differ significantly for either group at any time point. Despite not showing a statistically significant difference over time, CMJ had a small effect size for VOFT and SOFT. At the same time, the SJ showed a moderate effect size for VOFT and a small effect size for SOFT. Furthermore, there was no significant difference between groups for any variable. Therefore, it is concluded that the application of FT protocols oriented towards speed or strength as a complement to tactical technical training, over four weeks, promotes significant changes in different COD running parameters in under-20 soccer players.

RESUMO Diante da cronificação da infecção pelo HIV, fatores psicossociais surgem como potencializadores para elevação dos níveis de estresse nas PVHIV, bem como para o desequilíbrio imunológico e elevação da carga viral. O objetivo da presente pesquisa foi avaliar o nível de estresse, a contagem de linfócitos TCD4 + e a carga viral de pessoas vivendo com HIV submetidas a TARV, atendidas em um hospital público universitário. Tratou-se de um estudo observacional, transversal com 25 pacientes (40,76 anos± 9,88 anos) que vivem com HIV atendidos no ambulatório de um hospital público do Rio de Janeiro. Foi utilizado um questionário sociodemográfico para caracterização da amostra, o estresse foi avaliado através do Inventário de Sintomas de Stress de LIPP e observados exames laboratoriais recentes. Foi identificado estresse em 68% dos participantes, com predomínio de sintomas físicos e fase de resistência. Houve maior prevalência de estresse em pessoas com baixo nível socioeconômico, desemprego e diagnóstico recente. Não foram observados menores níveis de linfócitos TCD4 + ou maior carga viral nas pessoas com estresse.

ABSTRACT Given the chronicity of HIV infection, psychosocial factors emerge as potentiators for the elevation of stress levels in PLHIV, as well as for the immunological imbalance and elevation of the viral load. The present research objective was to evaluate the stress level, TCD4+ lymphocyte count and viral load of people living with HIV undergoing ART, treated at a public university hospital. This was an observational, cross-sectional research with 25 patients (40.76 years± 9.88 years) living with HIV treated at the outpatient clinic of a public hospital in Rio de Janeiro. A sociodemographic questionnaire was used to characterise the sample. Stress was evaluated through the LIPP Stress Symptom Inventory and observed in recent laboratory tests. Stress was identified in 68% of the participants, with a predominance of physical symptoms and a resistance phase. There was a higher prevalence of stress in people with low socioeconomic status, unemployment and recent diagnosis. Lower levels of CD4+ T lymphocytes or higher viral load were not observed in people with stress.

ABSTRACT High-throughput phenotyping (HTP) using vegetation indices (VIs) is an important data source for managing plant breeding programs and can be a promising tool in indirect selection. This study hypothesized that VIs are correlated with agronomic traits in corn, and therefore, HTP can be an auxiliary tool for selecting superior genotypes. The objectives were: i) to analyze the association between agronomic traits and VIs, and ii) to identify superior corn hybrids for the evaluated traits using multivariate techniques. Ten corn hybrids (AGRI 330, AGRI 340, FS575PWU, KTZ006VP3, MG545AW, MG580PW, MG711PW, MZ1780, MZ1952, and TROPI 102) were evaluated for plant height (PH), stem diameter (SD), and grain yield (GY). The VIs studied were NDVI, NDRE, EVI, GNDVI, SAVI, and MSAVI. Pearson’s correlation network was constructed to analyze the relationship between the variables, and a canonical analysis was performed to verify the inter-relationship between the variables and hybrids. The VIs evaluated are strongly positively correlated with each other and with PH. The most productive hybrids are MG545AW, FS575PWU and KTZ006VP3. Hybrid MZ1952 has higher correlations with VIs and PH. The findings reveal that VIs can be excellent auxiliary variables for selecting agronomically superior genotypes, being a promising alternative to increase corn breeding efficiency.

Abstract: Eucalyptus planted forests contribute to maximizing lumber production but problems such as longitudinal growth strain can negatively influence the quality of the products. Knowing dendrometric variables and wood properties can help in the prediction of longitudinal growth strain, mainly with the help of artificial intelligence. Thus, the aim of this research was to evaluate the use of artificial neural networks to predict longitudinal growth strain in Eucalyptus trees based on dendrometric variables, spacing between trees and wood density. The longitudinal growth strain was measured in trees of four Eucalyptus clones planted in three spacings. The diameter and height of each tree were measured. The basic wood density was determined. Artificial neural networks were used to estimate longitudinal growth strain as a function of dendrometric variables, tree spacing and wood density. The results showed that the artificial neural networks presented good results for training and validation, with most of them resulting in high correlation coefficient values. The trained artificial neural networks showed a correlation coefficient above 0,56. Artificial neural networks showed that the variables clone and basic wood density were the ones that most contributed to the prediction of longitudinal growth strain. On the other hand, the spacing between trees, the height of the tree and the diameter at breast height were not relevant to predict growth stresses.

ABSTRACT. This study aimed to perform a strategic diagnosis on a property specialized in breeding, rearing and finishing beef cattle in the southern region of Piauí. It was conducted at Agropecuária Alvorada, located in the countryside, municipality of Bom Jesus, PI, Brazil. The farm develops the full cycle of beef cattle production, which is divided into breeding, rearing and finishing. A SWOT analysis (which stands for Strengths, Weaknesses, Opportunities and Threats) was carried out, consisting of an assessment of the property’s internal and external environments. To evaluate the internal environment, an interview was held for data collection by means of questionnaires. The evaluation included: breeding management, sanitary management, nutritional management, infrastructure, workforce, technologies used in pasture formation, conservation and recovery, pasture management and zootechnical indices. To analyze the external environment, a group of people (experts) with deep knowledge of the subject addressed during the study was used as source of information. A matrix was generated with all the information from the SWOT analysis, strengths, weaknesses, opportunities and threats, culminating with the establishment of strategies to increase the productive efficiency of the cattle raising activity.

ABSTRACT Objective: To identify the presence of musculoskeletal pain during the working day among nursing professionals in material and sterilization centers. Method: A cross-sectional study with 36 nursing professionals who answered a questionnaire for personal characterization and diagnosis of musculoskeletal disorders and Corlett and Manenica's diagram of painful areas at the beginning and end of the working day. Frequency distribution analysis, Fisher's exact test and likelihood ratio were carried out. Results: The presence of pain was reported by 80.6% (n = 29) of the participants at the start of the working day and 94.4% (n = 34) at the end, and the prevalence of musculoskeletal disorders was 66.6% (n = 24). There was a statistically significant difference in the number of segments with pain between professionals with and without a diagnosis of musculoskeletal disorders, in the initial and final assessments. The lumbar spine had a higher prevalence of pain in both assessments. Conclusion: The prevalence of pain increased towards the end of the working day and indicates that there may be a relationship between the work process and the development of pain. It is important to identify working conditions that may contribute to the onset of pain and to adopt preventive measures.

RESUMEN Objetivo: Identificar la presencia de dolor musculoesquelético durante la jornada laboral entre los profesionales de enfermería de los centros de material y esterilización. Método: Estudio transversal con 36 profesionales de enfermería que respondieron a un cuestionario de caracterización personal y diagnóstico de trastornos musculoesqueléticos y al diagrama de Corlett y Manenica de zonas dolorosas al inicio y al final de la jornada laboral. Se analizaron la distribución de frecuencias, la prueba exacta de Fisher y los cocientes de probabilidad. Resultados: El 80,6% (n = 29) de los participantes declararon la presencia de dolor al inicio de la jornada laboral y el 94,4% (n = 34) al final, y la prevalencia de trastornos musculoesqueléticos fue del 66,6% (n = 24). Hubo una diferencia estadísticamente significativa en el número de segmentos con dolor entre los profesionales con y sin diagnóstico de trastornos musculoesqueléticos, en las evaluaciones inicial y final. La columna lumbar presentó una mayor prevalencia de dolor en ambas evaluaciones. Conclusión: La prevalencia de dolor aumentó hacia el final de la jornada laboral e indica que puede existir una relación entre el proceso de trabajo y el desarrollo de dolor. Es importante identificar las condiciones de trabajo que pueden contribuir a la aparición del dolor y adoptar medidas preventivas.

ABSTRACT Introduction: Surface treatment is an important technique to increase adhesion between implants and bones, improving its mechanical characteristics and consequently the patient’s comfort. Objectives: Ni-Cr alloys were the object of study in this work, with the purpose of analyzing and evaluating the effect of thin films deposition of titanium nitride via plasma, on its surface and comparing with cathodic cage (CC) and hollow cathode (HC) methods, for dental applications. Methods: Eighteen samples were prepared and the experiment was conducted in two steps: the pre-sputtering (1h, 350 °C, gases: Ar and H) and sputtering (4h, 450 °C, gases: Ar, Ni, and H). To characterize and compare the samples with those of reference, the Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Vickers Microhardness and wettability tests were used. Results: The results presented by SEM showed that during the surface treatment using CC, voids were formed, and using HC, the samples showed a more homogenous behavior. In microhardness tests, using a 25gf load, it was possible to observe that the HC method allowed an increase of 87% when compared to the reference and treated samples. Significance: Lastly, it can be concluded that both methods are suitable for Ni-Cr alloy surface treatment, and the HC technique, a method already used by dental professionals, presents better results due to the formation of a thicker film layer.
