Resumo Atécnica de vergamento da madeira por vaporização se apresenta como opção viável para projetos de estruturas curvilíneas, como as gridshells. Madeiras coníferas são comumente adotadas em estruturas de cobertura, pois além da desejada relação entre resistência mecânica e densidade, permitem o completo tratamento da seção transversal da peça. Entretanto, características como a predominância de alburno ou de cerne e a presença de defeitos são variáveis que afetam o desempenho estrutural. O objetivo deste estudo foi avaliar o limite de vergamento de lamelas de Acrocarpus flaxinifloius (cedro indiano) com raio de curvatura de 21 cm em diferentes espessuras. Também se investigou o impacto da predominância de alburno ou cerne e da presença de defeitos na força de vergamento. A literatura indica que a flexibilização plástica por vapor ocorre a 100°C, com 2,4 minutos para cada milímetro de espessura da lamela, parâmetros estes considerados neste estudo. A análise estatística indicou o limite de 8 mm de espessura para o vergamento das lamelas e a maior presença de alburno ou de cerne, bem como os defeitos da madeira, não afetou significativamente a força de vergamento. curvilíneas gridshells cobertura densidade peça Entretanto estrutural cedro indiano 2 espessuras 100C C 100 100°C 24 4 2, lamela 10 1

Abstract The technique of bending wood by vaporization presents itself as a viable option for curvilinear structural projects, such as gridshells. Coniferous woods are often used in roof structures because, in addition to the desired relationship between mechanical strength and density, they allow the complete treatment of the cross-section of the piece. However, characteristics such as the predominance of sapwood or heartwood and the presence of defects are variables that affect structural performance. The aim of this study was to evaluate the bending limit of Acrocarpus laxinifloius (Indian cedar) veneers with a bending radius of 21 cm at different thicknesses. The impact of the predominance of sapwood or heartwood and the presence of defects on the bending strength was also investigated. The literature indicates that plastic flexibilization by steam occurs at 100°C, with 2.4 minutes for each millimeter of lamella thickness, which were the parameters considered in this study. The statistical analysis indicated a thickness limit of 8 mm for the lamellae to bend and the greater presence of sapwood or heartwood, as well as wood defects, did not significantly affect the bending force. projects gridshells because density crosssection cross section piece However performance Indian cedar 2 thicknesses investigated 100C C 100 100°C 24 4 2. force 10 1

Abstract Introduction Juvenile nasopharyngeal angiofibroma (JNA) is a benign vascularized tumor that affects almost exclusively male adolescents. Surgery is the treatment of choice for JNA. Objectives The present study is a 42-year retrospective review of a series of JNA cases treated surgically without previous embolization. Methods The present is a retrospective, descriptive study based on medical records of 96 patients with JNA who underwent microscopic or endoscopic excision without previous embolization from 1978 to 2020 in a single institution. The patients were categorized according to the Andrews et al. stage, and data were collected on age, gender, tumor staging, surgical approach, affected side, and outcome. Results All patients were male, with an average age of 17 years. The predominant tumor stage consisted of type II, with 52.1%. A total of 33.3% of the patients were submitted to the microscopic technique and 66.7%, to the endonasal technique. The rate of intraoperative blood transfusion was of 17.7%. Conclusion The present study reinforces that resection of JNA in various stages is viable without previous artery embolization.

ABSTRACT The present study aimed to investigate the communication/training strategies and technological tools used by fitness coaches from Brazilian football teams during home-based training according to age categories (professional and youth), competitive level (1st, 2nd and 3rd/4th divisions) and sex (male and female). An online questionnaire was applied to collect data. Eighty-two fitness coaches from sixty-seven male and female football teams (professional and youth teams) answered the questionnaire. Message apps were the main communication route between fitness coaches and players during home-based training. Online spreadsheets were frequently used to control the training. Regarding equipment provided to players for training, 70.7% of male professional players used some equipment. In contrast, most female professional and youth players (both sexes) did not receive any equipment, respectively (p< 0.01). Male players who compete in the 1st and 2nd divisions received more equipment for training than those who compete in the 3rd and 4th divisions (p< 0.01). The main physical fitness variables trained by all players during home-based training were muscle strength, strength-endurance, and aerobic capacity. Training load and training response were applied through series/repetitions/time and effort perception scales, respectively. In conclusion, the financial differences between professional and youth teams and between males and females and competitive levels can induce different home-based training conditions in Brazilian football teams during lockdown-like situations, especially related to equipment available for training targeted physical qualities. Thus, players should be monitored closely during lockdown-like situations and provided appropriate support to facilitate their training.

Resumo Introdução: A doença renal crônica costuma ser assintomática e seu diagnóstico depende da realização de exames laboratoriais, com destaque para a creatinina sérica e pesquisa de proteinúria. Objetivo: Avaliar em uma amostra da população brasileira o conhecimento sobre o papel da creatinina sérica como marcador de função renal. Método: Estudo observacional transversal realizado na cidade de São Paulo (SP, Brasil), em que foi entrevistada uma população adulta aleatória. Resultados: Foram entrevistados 1138 indivíduos, com idade mediana de 36 anos (27–52); 55,1% do sexo feminino. Com relação ao marcador “creatinina”, 40,6% afirmaram que nunca realizaram tal dosagem. Quando questionados quanto ao conhecimento sobre a utilidade desse exame, somente 19,6% sabiam a sua função. As outras respostas foram “não sei” (71,6%), avaliar o funcionamento do coração (0,9%) e fígado (7,8%). Dos que afirmaram já terem realizado o exame de creatinina, somente 29,4% acertaram a função da creatinina. Ao dividir os grupos em “sabe” e “não sabe” a função da creatinina, percebeu-se diferença estatisticamente significante (p < 0,05) em relação ao grau de escolaridade, sexo feminino, ser aluno/trabalhador da saúde, ter dosado creatinina alguma vez, conhecer alguém com doença renal e maior idade. Na análise multivariada, a principal variável relacionada com conhecer a função da creatinina foi ter realizado o exame anteriormente (OR 5,16; IC 95% 3,16–8,43, p < 0,001). Conclusão: Há grande desconhecimento sobre a creatinina e seu uso em check-ups. Os resultados indicam que é necessário maior esforço por parte dos profissionais de saúde para divulgar o papel da creatinina sérica.

Abstract Introduction: Chronic kidney disease is usually asymptomatic, and its diagnosis depends on laboratory tests, with emphasis on serum creatinine and proteinuria. Objective: To assess knowledge on the role of serum creatinine as a biomarker of kidney function in a sample of the Brazilian population. Method: Cross-sectional observational study conducted in São Paulo (SP, Brazil), in which a random adult population was interviewed. Results: A total of 1138 subjects were interviewed, with a median age of 36 years old (27–52); 55.1% were female. Regarding the “creatinine” biomarker, 40.6% stated they had never performed such a test. When asked about their knowledge on the usefulness of this exam, only 19.6% knew its function. The other responses were “I don’t know” (71.6%), evaluating heart function (0.9%) and liver function (7.8%). Of those who reported they had already taken a creatinine test, only 29.4% correctly identified the role of creatinine. When dividing the groups into “knows” and “does not know” the function of creatinine, a statistically significant difference (p < 0.05) was observed regarding level of education, female sex, being a healthcare student/worker, having ever measured creatinine, knowing someone with kidney disease and older age. In the multivariate analysis, the main variable related to knowing the creatinine role was having previously taken the test (OR 5.16; 95% CI 3.16–8.43, p < 0.001). Conclusion: There is a significant lack of knowledge about creatinine and its use in checkups. The results indicate that greater efforts are needed from healthcare professionals to raise awareness on the role of serum creatinine.

A cardiomiopatia hipertrófica (CMH) é uma forma de doença do músculo cardíaco de causa genética, caracterizada pela hipertrofia das paredes ventriculares. O diagnóstico requer detecção por métodos de imagem (Ecocardiograma ou Ressonância Magnética Cardíaca) de qualquer segmento da parede do ventrículo esquerdo com espessura &gt; 15 mm, sem outra causa provável. A análise genética permite identificar mutações de genes codificantes de diferentes estruturas do sarcômero responsáveis pelo desenvolvimento da CMH em cerca de 60% dos casos, permitindo o rastreio de familiares e aconselhamento genético, como parte importante do manejo dos pacientes e familiares. Vários conceitos sobre a CMH foram recentemente revistos, incluindo sua prevalência de 1 em 250 indivíduos, não sendo, portanto, uma doença rara, mas subdiagnosticada. A vasta maioria dos pacientes é assintomática. Naqueles sintomáticos, a obstrução do trato de saída do ventrículo esquerdo (OTSVE) é o principal distúrbio responsável pelos sintomas, devendo-se investigar a sua presença em todos os casos. Naqueles em que o ecocardiograma em repouso ou com Manobra de Valsalva não detecta gradiente intraventricular significativo (&gt; 30 mmHg), devem ser submetidos à ecocardiografia com esforço físico para detecção da OTSVE.&nbsp;&nbsp; Pacientes com sintomas limitantes e grave OTSVE, refratários ao uso de betabloqueadores e verapamil, devem receber terapias de redução septal ou uso de novas drogas inibidoras da miosina cardíaca. Por fim, os pacientes adequadamente identificados com risco aumentado de morta súbita podem receber medida profilática com implante de cardiodesfibrilador implantável (CDI).

La miocardiopatía hipertrófica (MCH) es una forma de enfermedad cardíaca de origen genético, caracterizada por el engrosamiento de las paredes ventriculares. El diagnóstico requiere la detección mediante métodos de imagen (Ecocardiograma o Resonancia Magnética Cardíaca) que muestren algún segmento de la pared ventricular izquierda con un grosor &gt; 15 mm, sin otra causa probable. El análisis genético permite identificar mutaciones en genes que codifican diferentes estructuras del sarcómero responsables del desarrollo de la MCH en aproximadamente el 60% de los casos, lo que permite el tamizaje de familiares y el asesoramiento genético, como parte importante del manejo de pacientes y familiares. Varios conceptos sobre la MCH han sido revisados recientemente, incluida su prevalencia de 1 entre 250 individuos, por lo tanto, no es una enfermedad rara, sino subdiagnosticada. La gran mayoría de los pacientes son asintomáticos. En los casos sintomáticos, la obstrucción del tracto de salida ventricular izquierdo (TSVI) es el trastorno principal responsable de los síntomas, y su presencia debe investigarse en todos los casos. En aquellos en los que el ecocardiograma en reposo o la maniobra de Valsalva no detecta un gradiente intraventricular significativo (&gt; 30 mmHg), deben someterse a ecocardiografía de esfuerzo para detectar la obstrucción del TSVI. Los pacientes con síntomas limitantes y obstrucción grave del TSVI, refractarios al uso de betabloqueantes y verapamilo, deben recibir terapias de reducción septal o usar nuevos medicamentos inhibidores de la miosina cardíaca. Finalmente, los pacientes adecuadamente identificados con un riesgo aumentado de muerte súbita pueden recibir medidas profilácticas con el implante de un cardioversor-desfibrilador implantable (CDI).

Hypertrophic cardiomyopathy (HCM) is a form of genetically caused heart muscle disease, characterized by the thickening of the ventricular walls. Diagnosis requires detection through imaging methods (Echocardiogram or Cardiac Magnetic Resonance) showing any segment of the left ventricular wall with a thickness &gt; 15 mm, without any other probable cause. Genetic analysis allows the identification of mutations in genes encoding different structures of the sarcomere responsible for the development of HCM in about 60% of cases, enabling screening of family members and genetic counseling, as an important part of patient and family management. Several concepts about HCM have recently been reviewed, including its prevalence of 1 in 250 individuals, hence not a rare but rather underdiagnosed disease. The vast majority of patients are asymptomatic. In symptomatic cases, obstruction of the left ventricular outflow tract (LVOT) is the primary disorder responsible for symptoms, and its presence should be investigated in all cases. In those where resting echocardiogram or Valsalva maneuver does not detect significant intraventricular gradient (&gt; 30 mmHg), they should undergo stress echocardiography to detect LVOT obstruction. Patients with limiting symptoms and severe LVOT obstruction, refractory to beta-blockers and verapamil, should receive septal reduction therapies or use new drugs inhibiting cardiac myosin. Finally, appropriately identified patients at increased risk of sudden death may receive prophylactic measure with implantable cardioverter-defibrillator (ICD) implantation.

Abstract Background The SARS-CoV-2 outbreak has led to radical transformation in social, economic, and healthcare systems. This may lead to profound indirect consequences on clinical presentation and management of patients with ST-segment–elevation myocardial infarction. Objectives The objective of this study was to describe the characteristics, management, and outcomes of patients admitted with acute myocardial infarction with ST-segment elevation (STEMI), in two tertiary reference hospitals during the SARS-CoV-2 outbreak and compare them with patients admitted in the previous year. Methods We analyzed data from a multicenter STEMI registry from reference centers in the South Region of Brazil from March 2019 to May 2021. The beginning of the COVID-19 outbreak was considered to be March 2020 and compared to the same period in 2019. Only patients with STEMI submitted to primary percutaneous coronary intervention (PCI) were included in the analysis. Mortality rates were compared with chi-square test. All hypothesis tests had a two-sided significance level of 5%. Results A total of 1169 patients admitted with STEMI were enrolled in our registry, 635 of whom were admitted during the pandemic period. The mean age of our sample was 61.6 (± 12.4) years, and 66.7% of patients were male. Pain-to-door time and door-to-balloon time were longer during the pandemic period. However, there was no difference in mortality rates or major adverse cardiovascular outcomes (MACE). Conclusions We observed a stable incidence of STEMI cases in our registry during the SARS-CoV-2 outbreak with higher pain-to-door time and door-to-balloon time, without any influence on mortality rates however.

ABSTRACT. Bahiagrass (Paspalum notatum Flügge) is an important forage in South America and the United States because of its high palatability, resistance to trampling and grazing, and tolerance to cold, but it exhibits low seed yield and poor seed quality. Previous studies reported improvements in forage production and nutritive value in hybrids and ecotypes; however, information about seed yield and quality in forage bahiagrass is limited. This study aimed to characterize the seed yield and quality of nine P. notatum intraspecific hybrids and three controls: P. notatum ecotypes V4 and Bagual and cultivar Pensacola. Inflorescence density, 1,000-seed weight, seed yield and germination rate decreased in year 2 influenced by weather conditions and ergot. Seed yield ranged from 139 (Pensacola) to 1,158 (Bagual) kg ha-1 among all entries, where Bagual, C18, and V4 produced more than 974 kg ha-1, which was approximately seven times more than Pensacola. Bagual, C18, V4, 336, C15, 225, and D3 showed germination rates greater than 83%. In conclusion, Bagual had the highest seed yield and germination rate, whereas hybrids C18 and 336 showed high seed yield, 1,000-seed weight, and germination rate in both years. Bagual, C18, and 336 should be used in future breeding programs to improve seed production traits. Our study revealed that selection for seed production traits can result in improvements in seed yield and quality in bahiagrass.

RESUMO: A raiva é uma encefalite viral que acomete os mamíferos, incluindo humanos. O diagnóstico laboratorial rápido e eficaz do vírus da raiva é importante para a saúde pública. Este estudo teve como objetivo avaliar a viabilidade operacional, técnica e financeira da RT-qPCR em substituição à inoculação em camundongos para o diagnóstico da raiva na rotina laboratorial. Foram analisadas 316 amostras de cérebros de mamíferos, 121 positivas e 195 negativas, previamente diagnosticadas por imunofluorescência direta (IFD) e isolamento viral em camundongos, por inoculação intracerebral em camundongos. As amostras foram submetidas à técnica duplex TaqMan RT-qPCR. A precisão, sensibilidade e especificidade da RT-qPCR foram analisadas. Os custos para realizar a técnica de RT-qPCR foram analisados e comparados com o custo do isolamento viral em camundongos. Os resultados demostraram 99,37% de acurácia, 99,17% de sensibilidade e 99,49% de especificidade pela RT-qPCR quando relacionada aos resultados de IFD e isolamento viral em camundongos, que se mostrou uma técnica robusta e com repetibilidade. O tempo mínimo para diagnóstico positivo foi reduzido na RT-qPCR (1 dia) quando comparado ao isolamento viral em camundongos (9,64 dias), e com redução de 17,7% no custo pela técnica molecular. O presente estudo demonstrou que a técnica de biologia molecular é uma ferramenta eficiente para o diagnóstico da raiva na rotina laboratorial, podendo substituir o isolamento viral em camundongos.

ABSTRACT: Rabies is a viral encephalitis that affects mammals, including humans. Rapid and effective laboratory diagnosis of the rabies virus is critical for public health. This study evaluated the operational, technical, and financial viability of the RT-qPCR in replacement of inoculation in mice for diagnosing rabies in the laboratory routine. A total of 316 samples of mammalian brains were analyzed, 121 positives and 195 negatives, previously diagnosed by direct immunofluorescence (DIF) and mouse inoculation test (MIT). The samples were submitted to the duplex TaqMan RT-qPCR technique. The accuracy, sensitivity, and specificity of RT-qPCR were analyzed. We analyzed the costs for performing the RT-qPCR technique and compared it with the cost of MIT. The results showed 99.37% accuracy, 99.17% sensitivity, and 99.49% specificity by RT-qPCR when related to DIF and MIT results, which proved to be a robust and repeatable technique. The minimum time for a positive diagnosis was reduced in RT-qPCR (1 day) if compared to MIT (9.64 days), with a 17.7% reduction in the cost of the molecular technique. The present study demonstrated that the molecular biology technique is an efficient tool to diagnose rabies in the laboratory routine, being able to replace MIT.

RESUMO Introdução: O trauma atinge principalmente a população economicamente ativa, causando impacto social e econômico. O tratamento não operatório das lesões de órgãos sólidos tem como objetivo preservar a função do órgão, diminuindo a morbimortalidade envolvida nos tratamentos cirúrgicos. O objetivo do estudo foi demonstrar o perfil epidemiológico dos pacientes submetidos ao tratamento não operatório em um hospital de trauma, bem como avaliar o fatores associados ao óbito nesses pacientes. Métodos: Trata-se de uma coorte histórica de pacientes submetidos à tratamento não operatório de lesão de órgãos sólidos, em um hospital referência de trauma brasileiro, entre 2018 e 2022. Foram incluídos pacientes vítimas de trauma contuso e penetrante, analisando as características epidemiológicas, hemotransfusão e associação ou não com necessidade de abordagem cirúrgica. Resultados: Foram incluídos 365 pacientes no estudo. Trezentos e quarenta e três pacientes receberam alta (93,97%) e a taxa de sucesso no tratamento não operatório foi de de 84,6%. Houve associação entre o desfecho óbito e as seguintes lesões associadas: hemopneumotorax, fratura de esterno, dissecção de aorta e traumatismo crânio encefálico. Houve associação entre necessidade de transfusão e abordagem cirúrgica. Trinta e oito pacientes necessitaram de alguma abordagem cirúrgica. Conclusão: O perfil dos pacientes submetidos a TNO são homens jovens, vítimas de trauma contuso. O tratamento não operatório é seguro e apresenta alta taxa de sucesso.

ABSTRACT Introduction: Trauma primarily affects the economically active population, causing social and economic impact. The non-operative management of solid organ injuries aims to preserve organ function, reducing the morbidity and mortality associated with surgical interventions. The aim of study was to demonstrate the epidemiological profile of patients undergoing non-operative management in a trauma hospital and to evaluate factors associated with mortality in these patients. Methods: This is a historical cohort of patients undergoing non-operative management for solid organ injuries at a Brazilian trauma reference hospital between 2018 and 2022. Included were patients with blunt and penetrating trauma, analyzing epidemiological characteristics, blood transfusion, and association with the need for surgical intervention. Results: A total of 365 patients were included in the study. Three hundred and forty-three patients were discharged (93.97%), and the success rate of non-operative treatment was 84.6%. There was an association between mortality and the following associated injuries: hemothorax, sternal fracture, aortic dissection, and traumatic brain injury. There was an association between the need for transfusion and surgical intervention. Thirty-eight patients required some form of surgical intervention. Conclusion: The profile of patients undergoing non-operative treatment consists of young men who are victims of blunt trauma. Non-operative treatment is safe and has a high success rate.

Abstract Background A cost of illness (COI) study aims to evaluate the socioeconomic burden that an illness imposes on society as a whole. This study aimed to describe the resources used, patterns of care, direct cost, and loss of productivity due to systemic lupus erythematosus (SLE) in Brazil. Methods This 12-month, cross-sectional, COI study of patients with SLE (ACR 1997 Classification Criteria) collected data using patient interviews (questionnaires) and medical records, covering: SLE profile, resources used, morbidities, quality of life (12-Item Short Form Survey, SF-12), and loss of productivity. Patients were excluded if they were retired or on sick leave for another illness. Direct resources included health-related (consultations, tests, medications, hospitalization) or non-health-related (transportation, home adaptation, expenditure on caregivers) hospital resources. Costs were calculated using the unit value of each resource and the quantity consumed. A gamma regression model explored cost predictors for patients with SLE. Results Overall, 300 patients with SLE were included (92.3% female, mean [standard deviation (SD)] disease duration 11.8 [7.9] years), of which 100 patients (33.3%) were on SLE-related sick leave and 46 patients (15.3%) had stopped schooling. Mean (SD) travel time from home to a care facility was 4.4 (12.6) hours. Antimalarials were the most commonly used drugs (222 [74.0%]). A negative correlation was observed between SF-12 physical component and SLE Disease Activity Index (- 0.117, p = 0.042), Systemic Lupus International CollaboratingClinics/AmericanCollegeofRheumatology Damage Index (- 0.115, p = 0.046), medications/day for multiple co-morbidities (- 0.272, p < 0.001), SLE-specific drugs/day (- 0.113, p = 0.051), and lost productivity (- 0.570, p < 0.001). For the mental component, a negative correlation was observed with medications/day for multiple co-morbidities (- 0.272, p < 0.001), SLE-specific medications/day (- 0.113, p = 0.051), and missed appointments (- 0.232, p < 0.001). Mean total SLE cost was US$3,123.53/patient/year (median [interquartile range (IQR)] US$1,618.51 [$678.66, $4,601.29]). Main expenditure was medication, with a median (IQR) cost of US$910.62 ($460, $4,033.51). Mycophenolate increased costs by 3.664 times (p < 0.001), and inflammatory monitoring (erythrocyte sedimentation rate or C-reactive protein) reduced expenditure by 0.381 times (p < 0.001). Conclusion These results allowed access to care patterns, the median cost for patients with SLE in Brazil, and the differences across regions driven by biological, social, and behavioral factors. The cost of SLE provides an updated setting to support the decision-making process across the country.

Objective: The risk of suicide is higher among health care workers than other workers. This study investigated the association between social support and suicidal ideation and behavior during the COVID-19 pandemic among Brazilian health care workers. Methods: This study used data from 10,885 respondents to the first (time point 1 – between May and June of 2020) and second (time point 2 – between December 2020 and February 2021) cross-sectional online surveys about mental health and quality of life among Brazilian health care workers during the COVID-19 pandemic. The relationship between social support as the independent variable (time point 1) and suicidal ideation and behavior as the outcomes (time point 2) was investigated through logistic regression analysis. Results: Greater social support was associated with a significantly lower risk of reporting suicidal ideation and behavior in the month prior to follow-up assessment (adjusted OR: 0.71, 95%CI 0.66-0.76 and adjusted OR 0.61, 95%CI 0.54-0.68, respectively). These associations were independent of sex, age, feelings of loneliness, and self-reported psychiatric disorders. Conclusion: Social support is associated with a lower risk of suicidality among health care workers, and its protective role appears more closely related to suicidal behavior.
