ABSTRACT Objective To evaluate the in vitro and in vivo toxicities of polyethylene glycol-coated gold nanoparticles synthesized using a one-step process. Methods Gold nanoparticles were prepared via a co-precipitation method using polyethylene glycol, and the synthesis product was characterized. For the in vitro evaluation, a flow cytometry analysis with Annexin V and iodide propidium staining was used to assess cytotoxicity in MG-63 cells labeled with 10, 50, and 100µg/mL of nanoparticle concentration. For the in vivo evaluation, nanoparticles were administered intraperitoneally at a dose of 10mg/kg dose in 10-week-old mice. Toxicity was assessed 24 hours and 7 days after administration via histopathological analysis of various tissues, as well as through renal, hepatic, and hematopoietic evaluations. Results Synthesized nanoparticles exhibited different hydrodynamic sizes depending on the medium: 51.27±1.62nm in water and 268.12±28.45nm (0 hour) in culture medium. They demonstrated a maximum absorbance at 520nm and a zeta potential of -8.419mV. Cellular viability exceeded 90%, with less than 3% early apoptosis, 6% late apoptosis, and 1% necrosis across all labeling conditions, indicating minimal cytotoxicity differences. Histopathological analysis highlighted the accumulation of nanoparticles in the mesentery; however, no lesions or visible agglomeration was observed in the remaining tissues. Renal, hepatic, and hematopoietic analyses showed no significant differences at any time point. Conclusion Polyethylene glycol-coated gold nanoparticles exhibit extremely low toxicity and high biocompatibility, showing promise for future studies. glycolcoated glycol coated onestep one step process coprecipitation co precipitation characterized evaluation MG63 MG 63 MG-6 10 50 100µgmL µgmL 100µg mL µg concentration 10mgkg mgkg 10mg kg mg 10weekold weekold week old mice 2 tissues renal hepatic evaluations medium 5127162nm nm 51 27 1 62nm 268122845nm 268 12 28 45nm 0 ( hour 8.419mV. 8419mV mV 8 419mV -8.419mV 90 90% 3 apoptosis 6 conditions mesentery however Renal point biocompatibility studies MG6 MG- 5 26 8.419mV 9

Abstract The objective was to analyze the spatial distribution of pregnancy in children under 14 years and six months by Brazilian region and municipality and sociodemographic and health characteristics of pregnant women and live births. Ecological study analyzing the Live Birth Information System (SINASC) from 2011 to 2021 in three age groups (< 14 years and six months, 15-19 years, and 20 years and above) by demographic and birth variables. We applied the Global and Local Moran. A total of 127,022 live births to girls aged 10-14 years were identified during the period, most of whom were Black, 21.1% in common-law or married relationships, with a lower proportion of seven prenatal care appointments and enrollment in the first trimester, a higher proportion of low birth weight and low Apgar score, residing in the North and Northeast. The mean live birth rate for 10-to-14-year-old girls was significantly autocorrelated with space, especially in municipalities of the Midwest and North. Pregnancy from 10 to 14 years of age reveals several vulnerabilities suffered by these girls due to pregnancy at an early age, which is more common among Black women, with implications for morbimortality for them and their children and the presumed violence in these cases, including denied access to legal abortion.

Abstract Background Infantile epileptic spasms syndrome (IESS) is a rare but severe condition affecting children early and is usually secondary to an identifiable brain disorder. It is related to psychomotor deterioration in childhood and epilepsy in adult life. Treatment is challenging as infantile spasms may not respond to most antiseizure medication, and relapse is frequent. Objective To evaluate the literature regarding treatment of IESS and provide a practical guidance to a healthcare system with limited resources. Methods An expert committee from the Brazilian Society of Child Neurology reviewed and discussed relevant scientific evidence in the treatment of IESS regarding the drugs available in Brazil. Results Oral prednisolone and vigabatrin are the most common drugs used as first-line therapy; they are efficient and affordable therapy as both are available in the Brazilian unified health system (SUS, in the Portuguese acronym). Intramuscular adrenocorticotropic hormone (ACTH) presents similar efficacy as oral prednisolone but has a higher cost and is not available in Brazil. Other antiseizure medications such as topiramate, levetiracetam, or benzodiazepines have limited response and are prescribed as adjuvant therapy. If the health service has nutritionists, a ketogenic diet should be implemented for those not responding to hormonal and vigabatrin treatment. Epilepsy surgery is mainly indicated for patients with focal lesions that do not respond to pharmacological therapy. Conclusion Early treatment of IESS with efficient drugs is feasible in our country. Using standard protocols increases the odds of achieving complete cessation in a shorter time and decreases relapse.

Resumo Antecedentes A síndrome do espasmo epiléptico infantil (IESS) é uma condição rara, mas grave, que afeta crianças precocemente e geralmente é secundária a um distúrbio cerebral identificável, estando relacionada a deterioração psicomotora na infância e a epilepsia na vida adulta. O tratamento é desafiador, pois os espasmos infantis podem não responder à maioria dos medicamentos anticrises e as recidivas são frequentes. Objetivo Avaliar a literatura sobre o tratamento de IESS e fornecer uma orientação prática para um sistema de saúde com recursos limitados. Métodos Um comitê de especialistas da Sociedade Brasileira de Neurologia Infantil revisou e discutiu evidências científicas relevantes no tratamento da IESS em relação aos medicamentos disponíveis no Brasil. Resultados Prednisolona oral e vigabatrina são os fármacos mais comumente usados como terapia de primeira linha; são eficientes e acessíveis, já que ambos estão disponíveis no sistema único de saúde brasileiro (SUS). O ACTH intramuscular apresenta eficácia semelhante à prednisolona oral, mas tem custo mais elevado e não está disponível no Brasil. Outros medicamentos anticonvulsivos, como topiramato, levetiracetam ou benzodiazepínicos, têm resposta limitada e são prescritos como terapia adjuvante. Se o serviço de saúde tiver nutricionista, deve-se implementar dieta cetogênica para aqueles que não respondem ao tratamento hormonal e vigabatrina. A cirurgia de epilepsia é indicada principalmente para pacientes com lesões focais que não respondem à terapia farmacológica. Conclusão O tratamento precoce da IESS com fármacos eficazes é factível em nosso meio. O uso de protocolos padronizados aumenta as chances de alcançar a cessação completa em um tempo menor e diminui a recaída.

Abstract Ketogenic dietary therapies (KDTs) are a safe and effective treatment for pharmacoresistant epilepsy in children. There are four principal types of KDTs: the classic KD, the modified Atkins diet (MAD), the medium-chain triglyceride (MCT) diet, and the low glycemic index diet (LGID). The International Ketogenic Diet Study Group recommends managing KDTs in children with epilepsy. However, there are no guidelines that address the specific needs of the Brazilian population. Thus, the Brazilian Child Neurology Association elaborated on these recommendations with the goal of stimulating and expanding the use of the KD in Brazil.

Resumo As terapias dietéticas cetogênicas (TDC) são um tratamento seguro e eficaz para epilepsia farmacorresistente em crianças. Existem quatro tipos principais de TDCs: a dieta cetogênica (DC) clássica, a dieta de Atkins modificada (DAM), a dieta de triglicerídeos de cadeia média (DTCM) e a dieta de baixo índice glicêmico (DBIG). O Grupo Internacional de Estudos de Dietas Cetogênicas (International Ketogenic Diet Study Group) propõe recomendações para o manejo da DC em crianças com epilepsia. No entanto, faltam diretrizes que contemplem as necessidades específicas da população brasileira. Assim, a Associação Brasileira de Neurologia Infantil elaborou essas recomendações com o objetivo de estimular e expandir o uso da DC no Brasil.

Abstract This paper provides general expressions for Bartlett and Bartlett-type correction factors for the likelihood ratio and gradient statistics to test the dispersion parameter vector in heteroscedastic symmetric nonlinear models. This class of regression models is potentially useful to model data containing outlying observations. Furthermore, we develop Monte Carlo simulations to compare size and power of the proposed corrected tests to the original likelihood ratio, score, gradient tests, corrected score test, and bootstrap tests. Our simulation results favor the score and gradient corrected tests as well as the bootstrap tests. We also present an empirical application. Bartletttype type observations Furthermore application

ABSTRACT Prune belly syndrome is a rare congenital disease of unknown etiology that is present in one in every 40 thousand live births, and predominantly affects males, at a ratio of 4:1. In males, it presents with anomalies in the urinary system, absence of abdominal muscles, bilateral cryptorchidism, and infertility. In women, the syndrome has variable presentations, but fertility is preserved. Searching the medical literature, we found only one case of prune belly syndrome in pregnant women. Therefore, the patient in this report is the second case. She was primiparous, 25-years-old, with no abdominal muscles, severe congenital kyphoscoliosis, and pulmonary restriction. Elective cesarean section was performed at 37 weeks of gestation due to maternal risk of uterine rupture by transverse presentation and fetal risk of intrauterine growth restriction. The pre-anesthetic approach defined that general anesthesia might have more risks for the patient due to severe maternal lung disease compared to ultrasound-guided locoregional anesthesia. During prenatal care, there were some maternal complications, such as asthma exacerbations, abdominal pain, and constipation. The newborn was born small for gestational age and this can possibly be explained by maternal restrictive lung capacity. The newborn presented with Apgar score 8/9 and tachypnea, but improved after two hours of life.

Abstract Objectives To analyze the efficiency of a multigenic targeted massively parallel sequencing panel related to endocrine disorders for molecular diagnosis of patients assisted in a tertiary hospital involved in the training of medical faculty. Material and methods Retrospective analysis of the clinical diagnosis and genotype obtained from 272 patients in the Endocrine unit of a tertiary hospital was performed using a custom panel designed with 653 genes, most of them already associated with the phenotype (OMIM) and some candidate genes that englobes developmental, metabolic and adrenal diseases. The enriched DNA libraries were sequenced in NextSeq 500. Variants found were then classified according to ACMG/AMP criteria, with Varsome and InterVar. Results Three runs were performed; the mean coverage depth of the targeted regions in panel sequencing data was 249×, with at least 96.3% of the sequenced bases being covered more than 20-fold. The authors identified 66 LP/P variants (24%) and 27 VUS (10%). Considering the solved cases, 49 have developmental diseases, 12 have metabolic and 5 have adrenal diseases. Conclusion The application of a multigenic panel aids the training of medical faculty in an academic hospital by showing the picture of the molecular pathways behind each disorder. This may be particularly helpful in developmental disease cases. A precise genetic etiology provides an improvement in understanding the disease, guides decisions about prevention or treatment, and allows genetic counseling.

RESUMO Objetivo Avaliar a concordância entre instrumentos de avaliação quantitativa do palato duro. Método Este estudo transversal foi realizado com uma amostra de 30 crianças de 6 a 11 anos de Santa Maria, sul do Brasil. Os instrumentos de medidas do palato avaliados foram: paquímetro digital, utilizado diretamente na cavidade oral e em modelos de gesso, arco tridimensional Korkhaus, usado diretamente na cavidade oral e em modelos de gesso, e Dolphin Imaging Software utilizado para medições em tomografia computadorizada de feixe cônico (CBCT). A concordância entre os diferentes instrumentos foi avaliada por meio do Coeficiente de Correlação Intraclasse (ICC). Resultados As médias de todas as dimensões transversais obtidas pela tomografia computadorizada de feixe cônico foram menores do que as dos outros instrumentos - os valores de concordância na largura entre os caninos e na largura entre os primeiros molares foram baixos na comparação entre a tomografia computadorizada de feixe cônico e os demais instrumentos. Na largura entre o primeiro e o segundo pré-molar, todas as comparações apresentaram valores de concordância aceitáveis. Valores de concordância aceitáveis também foram obtidos ao comparar a profundidade do palato na região do segundo pré-molar com o uso de um divisor de arco dentro da cavidade oral e no gesso. Conclusão A maioria dos instrumentos apresentou concordância satisfatória nas medidas relacionadas ao plano transverso do palato duro. Porém, quando avaliado o plano vertical, apenas o divisor de arco aplicado tanto no gesso quanto na cavidade oral apresentou concordância ideal.

ABSTRACT Purpose To evaluate the agreement among instruments of the quantitative evaluation of hard palate. Methods This cross-sectional study was performed with a sample of 30 children aged 6 to 11 from Santa Maria, Southern Brazil. The instruments for palate measurements evaluated were: digital caliper, used directly in the oral cavity and in plaster casts, Korkhaus tridimensional bow, used directly in the oral cavity and in plaster casts, and Dolphin Imaging Software used for measurements in cone-beam computed tomography (CBCT). The agreement among different instruments was evaluated using the Intraclass Correlation Coefficient (ICC). Results The means of all transversal dimensions obtained by cone-beam computed tomography were lower than those of the other instruments - the agreement values in the width between the canines and in the width between the first molars were lower when comparing the cone-beam computed tomography and the other instruments. In the width between the first and second premolars, all comparisons showed acceptable agreement values. Good concordance values were obtained when comparing the palate depth at the second premolar region when using a bow divider inside the oral cavity and in the cast. Conclusion Most instruments presented satisfactory agreement in the measurements related to the transverse plane of the hard palate. However, when the vertical plane was evaluated, only the bow divider applied to both cast and oral cavity presented ideal agreement.

Resumen Introducción: la energía eólica ha crecido de forma acelerada en los últimos 20 años y los sitios para instalar parques eólicos se empiezan a agotar. Las turbinas eólicas de pequeña escala representan una alternativa viable, en particular en zonas boscosas: de bajo potencial eólico y alta turbulencia. Objetivo: presentar una revisión de los perfiles aerodinámicos para aerogeneradores de pequeña escala, para determinar su posible aplicación en zonas boscosas. Materiales y métodos: se efectúa una revisión literaria en las bases de datos Web of Science y Scopus, sobre turbinas eólicas de pequeña escala de eje horizontal, en las revistas Energy, Journal of Wind Engineering and Industrial Aerodynamics, Renewable and Sustainable Energy Reviews y Renewable Energy, entre otras. Se define una clasificación de tres grandes grupos para los perfiles aerodinámicos: de uso muy frecuente, de uso con frecuencia media y de uso con baja frecuencia. Resultados: los perfiles de uso muy frecuente son el SG6043, S809 y NACA0012, siendo el primero de ellos el que presenta mejor desempeño aerodinámico. A pesar de esto, otros perfiles como el SH3055 son ampliamente usados en turbinas eólicas de pequeña escala. Conclusiones: un perfil adecuado para una turbina eólica de pequeña escala para zonas boscosas debe ser diseñado para regulación por pérdida (stall) y poseer una alta robustez ante cambios de rugosidad superficial. El perfil con mayor potencial, según la literatura para esta aplicación, es el SG6043, siendo 110 % y 85 % más eficiente que NACA0012 y S809, respectivamente, para un Re de 2 x 105; empero, se requiere más investigación en temas como desempeño aerodinámico de los perfiles ante altos niveles de turbulencia.

Abstract Introduction: Wind energy has grown rapidly in the last 20 years and sites to install full-scale wind farms are starting to run out. Small-scale wind turbines represent a feasible alternative, particularly in forested areas of low wind potential and high turbulence. Objective: to present a review of the aerodynamic profiles for small-scale wind turbines, to determine their possible application in wooded areas. Materials and methods: a review of small-scale horizontal axis wind turbines is carried out using the Web of Science and Scopus databases mainly on the journals: Energy, Wind Engineering and Industrial Aerodynamics, Renewable and Sustainable Energy Reviews, and Renewable Energy. A classification of three large groups is defined for the aerodynamic profiles: very frequent use, medium frequency use and low frequency use. Results: the profiles of very frequent use are the SG6043, S809 and NACA0012, the first of them is the one having the best aerodynamic performance. Despite this, other profiles such as the SH3055 are widely used in the small-scale wind turbine field. Conclusions: a suitable profile for a small-scale wind turbine for forested areas should be designed for stall regulation and have low sensitivity against changes in surface roughness. The profile with the greatest potential, according to the literature for this application, is the SG6043, being 110 % y 85 % more efficient than NACA0012 and S809, respectively, for a Re of 2 x 105; however, more research is required on issues such as aerodynamic performance of the profiles at high levels of turbulence.

Resumo O estudo avaliou a qualidade da água potável de 45 escolas públicas na cidade de Curitiba, Brasil. Amostras de água foram coletadas de dois pontos diferentes de cada escola: o bebedouro utilizado pelos alunos (n = 45) e a torneira da cozinha (n = 45), totalizando 90 amostras. As amostras foram submetidas à análise de parâmetros legais: dosagem de cloro livre, contagem de bactérias heterotróficas, presença de coliformes totais e Escherichia coli. Além disso, a análise de enterococos também foi incluída como um indicador microbiológico complementar de contaminação fecal. As cepas de enterococos isolados foram identificadas e submetidas ao teste de sensibilidade a antibióticos. Em relação aos parâmetros legais, 35,5% (n = 16) das 45 escolas avaliadas não atenderam aos padrões de qualidade da água da legislação brasileira. Embora nenhuma das 90 amostras exibisse a presença de Escherichia coli, observou-se que 6,6% (n = 6) das amostras analisadas apresentaram contaminação por enterococos. No teste de sensibilidade aos antibióticos, as cepas isoladas demonstraram um comportamento semelhante, apresentando resistência a seis antibióticos e sensibilidade intermediária a um (estreptomicina). A água potável destinada ao consumo humano nas escolas públicas pode representar um risco à saúde dos estudantes, uma vez que a contaminação fecal por enterococos foi confirmada e considerada uma fonte de genes com resistência a antimicrobianos que podem ser facilmente disseminados para outras pessoas. Este estudo reforça a importância do monitoramento de indicadores microbiológicos complementares para garantir a qualidade da água, uma vez que a contaminação fecal foi detectada apenas quando parâmetros alternativos foram inseridos, enfatizando sua relevância para avaliar a água de maneira mais eficaz e salvaguardar a saúde pública.

Abstract The study evaluated the drinking water quality from 45 public schools in the city of Curitiba, Brazil. Water samples were harvested from two different points at each school: the first one, drinking fountain used by students (n=45) and the second, kitchen faucet (n=45), comprising 90 samples. The samples were submitted to analysis according to current legislation, such as: dosage of free chlorine; colony counts of heterotrophic bacteria; presence of total coliform bacteria and Escherichia coli. In addition, an enterococci analysis was also included as a complementary microbiological indicator of fecal contamination. The isolated strains of enterococci were identified and submitted to an antibiotic susceptibility test. In relation to the legal parameters, 35.5% (n=16) of the 45 schools evaluated did not meet the quality water standards set by the Brazilian legislation. Although none of the 90 samples exhibited the presence Escherichia coli, 6.6% (n=6) of the analyzed samples presented enterococci contamination. Regarding the antibiotic susceptibility test, the isolated strains demonstrated a similar behavior, became resistant to six antibiotics and had intermediate sensitivity to one (Streptomycin) of the nine antibiotics tested. The drinking water destined for human consumption in the public schools may pose health risks for students since the fecal contamination by enterococci was confirmed, and it could be observed that the water may be a source of genes from bacteria resistant to antimicrobials. This study reinforces the importance of monitoring complementary microbiological indicators to assure water quality, seeing that fecal contamination was detected only when alternative parameters were inserted, emphasizing the relevance of including microbiological indicators beyond what the legislation requires to evaluate the drinking water more effectively and to safeguard public health.

Abstract Clusia grandiflora belongs to an important botanical family which is known for its medicinal value, however there are few reports in literature about the species, highlighting the relevance of this study. Anatomical studies with leaves and stems were performed using traditional techniques. In this investigation it was identified particularities of the species such as the presence of vascular system arranged in an opened arc-shaped with the flexed ends towards the inside of the arch with accessory bundles in the petiole. In histochemical studies, performed with different reagents, alkaloids, phenols substances, carbohydrates and lipids were located. The cytotoxic activity of the extracts was performed by tetrazole salt and showed promising results for ethanolic extracts of stems (IC50 human colon cells of 24.30 μg/ mL) and leaves (IC50 ascites gastric cells of 44.15 μg/ mL), without cell membrane disruption of erythrocytes. The antibacterial activity was evaluated by tryptic soy agar and minimal inhibitory concentration assays and showed positive results for Pseudomonas aeruginosa and Escherichia coli, with better result for adventitious roots (32 μg/ mL and 16 μg/ mL, respectively), stems (64 μg/ mL and 32 μg/ mL, respectively) and leaves (64 μg/ mL and 32 μg/ mL, respectively) ethanolic extracts. Thus, these studies were able to characterize the species and show its potential as promising source of active substances.

OBJECTIVES: High-throughput sequencing of genomes, exomes, and disease-focused gene panels is becoming increasingly common for molecular diagnostics. However, identifying a single clinically relevant pathogenic variant among thousands of genetic polymorphisms is a challenging task. Publicly available genomic databases are useful resources to filter out common genetic variants present in the population and enable the identification of each disease-causing variant. Based on our experience applying these technologies at Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP), São Paulo, Brazil, we recognized that the Brazilian population is not adequately represented in widely available genomic databases. METHODS: Here, we took advantage of our 5-year experience as a high-throughput sequencing core facility focused on individuals with putative genetic disorders to build a genomic database that may serve as a more accurate reference for our patient population: SELAdb. RESULTS/CONCLUSIONS: Currently, our database comprises a final cohort of 523 unrelated individuals, including patients or family members managed by different clinics of HCFMUSP. We compared SELAdb with other publicly available genomic databases and demonstrated that this population is very heterogeneous, largely resembling Latin American individuals of mixed origin, rather than individuals of pure European ancestry. Interestingly, exclusively through SELAdb, we identified a spectrum of known and potentially novel pathogenic variants in genes associated with highly penetrant Mendelian disorders, illustrating that pathogenic variants circulating in the Brazilian population that is treated in our clinics are underrepresented in other population databases. SELAdb is freely available for public consultation at: http://intranet.fm.usp.br/sela

Abstract Purpose: To evaluate the efficacy of the cellulosic exopolysaccharide membrane (CEM) as a urethral reinforcement for urethrovesical anastomosis. Methods: Twenty eight rabbits were submitted to urethrovesical anastomosis with or without CEM reinforcement. The animals were divided into 4 groups: C7, CEM7, C14 and CEM14: (C= only anastomosis or CEM = anastomosis + CEM), evaluated after 7 weeks, and 14 weeks. The biointegration and biocompatibility of CEM were evaluated according to stenosis, fistula, urethral wall thickness, urethral epithelium, rate of inflammation and vascularization. Results: Between the two experimental groups, the difference in the number of stenosis or urinary fistula was not statistically significant. The morphometric analysis revealed preservation of urethral lumen, well adhered CEM without extrusion, a controlled inflammatory process and implant vascularization. The urothelium height remained constant over time after CEM reinforcement and the membrane wall was thicker, statistically, after 14 weeks. Conclusion: The absence of extrusion, stenosis or urinary fistula after 14 weeks of urethrovesical anastomosis demonstrates cellulosic exopolysaccharide membrane biocompatibility and biointegration with tendency to a thicker wall.

Resumo: A necessidade de monitoramento do mercado imobiliário como instrumento de avaliação da efetividade das políticas de planejamento urbano no território é etapa crucial para a boa gestão pública. Nesse sentido, o presente texto tem por objetivo construir o índice de preços para os imóveis transacionados no Distrito Federal entre 2003 e 2012 por meio do método de vendas repetidas. O índice proposto permite a avaliação de políticas públicas e seus impactos territoriais no preço dos bens imóveis, por meio do monitoramento contínuo da evolução dos preços de imóveis no Distrito Federal. Esse acompanhamento contínuo constitui-se em instrumento da política urbana no âmbito da capital federal, o qual servirá não somente para avaliação de políticas públicas, como também de operacionalização das mesmas, a partir da integração com instrumentos urbanísticos, tais como a outorga onerosa.

Abstract: The need for monitoring the real estate market to evaluate the effectiveness of urban planning policies in the territory is crucial step towards good governance, in this sense, this article aims to build the price index for properties transacted in Distrito Federal between 2003 and 2012 through the repeat sales method. The proposed index allows the evaluation of public policies and their territorial impact on the price of real estate, through the assessment of the evolution of real estate prices in the Distrito Federal. This continuous monitoring constitutes a tool of urban policy in the federal capital, which will serve not only for evaluation of public policies, as well as implementation of the same, from the integration with urban instruments, such as the onerous grant.
