This work aims to deposit silica (SiO2) on polyamide 6,6 fabrics by hybrid corona-dielectric barrier discharge plasma at atmospheric pressure. The reactor used, developed at the Laboratory of Plasma and Processes of the Aeronautics Institute of Technology (LPP/ITA), allows the treatment of fabric surfaces by activation and plasma deposition processes, aiming, in this order, the alteration of wettability and the deposition of silica on its surface, using a silicic acid solution (Si(OH)4) as a silica precursor. The morphology of the deposited films was evaluated by scanning electron microscopy (SEM). To identify the chemical modifications generated by the plasma treatment, the untreated and treated samples were analyzed by Fourier transform infrared spectroscopy with attenuated reflectance (FTIR-ATR) and Energy Dispersive Spectroscopy (EDS). The thermal behavior of the treated and untreated samples was evaluated by Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Additionally, X-ray diffraction (XRD) was also used to identify crystalline phases in the film. The results showed that plasma processing proved to be an effective technique for modifying the surface characteristics of polyamide 6,6.

Resumo A fertilização das figueiras é realizada por muitos produtores da região de Torres Novas de forma intuitiva, refletindo-se em baixas produções e baixa qualidade dos frutos. Atendendo a este problema, foi objetivo deste estudo avaliar a produção, o crescimento e a queda dos figos, comparando a fertilização que é realizada com base na intuição do agricultor (tradicional) com a fertilização que é baseada na produção esperada, na análise de solos e de folhas do ano anterior e nos valores de referência (racional). Os resultados indicaram que a fertilização racional teve uma significativa influência na produtividade das figueiras da cultivar ‘Preto de Torres Novas’ e ainda no crescimento em diâmetro dos figos, induzindo maior formação de frutos e reduzindo a queda dos mesmos. Já no caso da cultivar ‘Pingo de Mel’, nenhuma das modalidades de fertilização mostrou um efeito considerável na produtividade e no crescimento em diâmetro dos frutos em ambos os anos. Não houve diferenças significativas na evolução do número de figos vindimos/ramo em 2021. Verificou-se, no entanto, uma redução da queda dos figos em ambos os anos nas figueiras que foram sujeitas a uma fertilização racional. Este estudo foi realizado no âmbito do projeto GoFigo Produção, iniciativa 321, financiado pelo Programa de Desenvolvimento Rural 2014-2020 que teve como objetivo melhorar a qualidade dos pomares de figueiras através da modernização das técnicas utilizadas e da eficiente utilização do solo.

Abstract The fertilization of fig trees is carried out intuitively by many producers in Torres Novas region, resulting in both low yields and low fruit quality. The objective of this study was to evaluate production, growth and figs shedding by comparing the farmers’ traditional fertilization with the rational fertilization, i.e. fertilization based on the expected production and the soil and leaf analysis of the previous year. The results showed that rational fertilization had a major impact on the productivity on the Preto de Torres Novas' cultivar. The figs were larger in diameter and dropped less. In 'Pingo de Mel' cultivar, none of the different fertilization methods showed a different effect on productivity and growth in either years. There were no differences in the development of the number of figs harvested per branch in 2021. With rational fertilization, however, a decrease in fig drop was recorded in both years. This study was carried out as part of the GoFigo Producão project funded by Programa de Desenvolvimento Rural 2014-2020, which aimed to improve the quality of fig orchards through the modernization of the techniques used and the efficient use of the soil.

Abstract Objective: Congenital hyperinsulinism (CHI) is a heterogeneous genetic disease characterized by increased insulin secretion and causes persistent hypoglycemia in neonates and infants due to dysregulation of insulin secretion by pancreatic β cells. Babies with severe hypoglycemia and for whom medical treatment has been ineffective usually require surgical treatment with near-total pancreatectomy. To evaluate the clinical and surgical aspects affecting survival outcomes in babies diagnosed with CHI in a single tertiary care center. Methods: Retrospective Cohort study involving a single university tertiary center for the treatment of CHI. The authors study the demographics, clinical, laboratory, and surgical outcomes of this casuistic. Results: 61 % were female, 39 % male, Birth weight: 3576 g (±313); Age of onset of symptoms: from the 2nd hour of life to 28 days; Time between diagnosis and surgery ranged between 10 and 60 days; Medical clinical treatment, all patients received glucose solution with a continuous glucose infusion and diazoxide. 81 % of the patients used corticosteroids, 77 %. thiazide, 72 % octreotide, 27 % nifedipine; Neurological sequelae during development and growth: 54 % had some degree of delay in neuropsychomotor development, 27 % obesity. Surgery was performed open in 6 and 12 minimally invasive surgery (MIS). Histopathology: 2 focal and 16 diffuse, Length of stay (days) was lower in MIS (p < 0.05). Survival was 100 %. Conclusions: CHI is a rare and difficult-to-manage tumor that must be performed in a multidisciplinary and tertiary center. Most surgical results are good and the laparoscopic approach to disease has been the best choice for patients.

ABSTRACT Objective: To evaluate the clinical and radiographic response of pulp-dentin complex after selective caries removal with or without pulp lining in primary teeth. Material and Methods: Twenty-four primary molars with deep occlusal caries lesions and without pulpal alterations were selected from children, both genders, aged between 5 and 9 years old. After selective caries removal, the teeth were divided into three groups: without cavity liner (Group I), calcium hydroxide cement - CH (Group II), and Mineral trioxide aggregate - MTA (Group III). The final restoration was performed with resin-modified glass ionomer cement. Clinical and radiographic assessments were conducted at 6-month follow-up. The Kappa test determined intraexaminer reliability. Fisher's exact test evaluated intergroup comparisons (p<0.05). Results: All teeth showed clinical and radiographic success at the 6-month follow-up without statistically significant differences (p>0.05). Conclusion: Selective caries removal without cavity lining was acceptable for deep caries lesions in primary teeth.

Resumo Técnicas modernas de investigação não destrutiva e ferramentas computacionais para análise não linear permitem compreender o comportamento estrutural e danos em edifícios existentes, visando a menor intervenção possível. A intervenção cuidadosa e mínima é essencial para preservar a autenticidade do patrimônio cultural construído. Uma investigação de abordagem histórica, experimental e numérica foi realizada no Theatro Municipal do Rio de Janeiro, no Brasil, edifício de arquitetura eclética do início do século XX. Suas cúpulas e abóbada em alvenaria possuem pinturas de renomados artistas no intradorso e foram reforçadas na década de 1970. A metodologia adotada baseou-se na anamnese, caracterização e observação da estrutura por meio de ensaios não destrutivos e na avaliação de sua vulnerabilidade por análises não lineares de modelos numéricos calibrados. Diversas hipóteses de recalque diferencial sob ações gravitacionais foram investigadas, buscando reproduzir o padrão de fissuração e identificar as causas dos danos nas alvenarias antes do reforço. A análise não linear da estrutura permitiu avaliar as causas dos danos observados, estimar o nível de segurança, identificar as partes mais vulneráveis e caracterizar os mecanismos de colapso, além de demonstrar a eficácia das medidas de intervenção adotadas no passado. existentes possível construído histórica Janeiro Brasil XX 1970 baseouse baseou se anamnese calibrados investigadas reforço observados segurança colapso passado 197 19 1

Abstract Modern non-destructive investigation techniques and computational tools for nonlinear analysis allow understanding the structural behavior and damage of existing buildings, aiming at the least possible extent of intervention. Careful and minimal intervention is essential to preserve the authenticity of the built cultural heritage. An investigation with a historical, experimental, and numerical approach was carried out in the Theatro Municipal do Rio de Janeiro, in Brazil, a building with an eclectic architecture from the beginning of the twentieth century. Its masonry domes and vault have paintings by renowned artists on their intrados and were strengthened in the 1970s. The adopted methodology was based on anamnesis, characterization and observation of the structure employing non-destructive tests, and on the assessment of its vulnerability by nonlinear analyses of calibrated numerical models. Several hypotheses of differential settlement under gravitational actions were investigated, seeking to reproduce the cracking pattern and to identify the causes of damage to the masonry domes and vault before the strengthening. The nonlinear analysis of the structure allowed to evaluate the causes of the observed damage, assess the level of safety, identify the most vulnerable parts, and characterize the collapse mechanisms, in addition to demonstrating the efficiency of the intervention measures adopted in the past. nondestructive non destructive buildings heritage historical experimental Janeiro Brazil century 1970s s anamnesis tests models investigated strengthening safety parts mechanisms past

SUMMARY OBJECTIVE: The aim of this study was to compare the obstetric and perinatal complications in women who became pregnant with autologous oocytes and those who received donated oocytes (DO) in intracytoplasmic sperm injection cycles (ICSI). METHODS: A retrospective cohort study was carried out by collecting data from medical records between 2019 and 2022. Only patients who underwent ICSI in an induced cycle using their own or freshly DO, with male infertility factor and tubal factor, were included. RESULTS: A total of 120 patients were assessed, comprising 51 cases utilizing their own oocytes (control group) and 69 cases employing DO (study group). Patients receiving DO (n=69) exhibited a significantly higher mean age compared to those utilizing their own oocytes (n=51) (41.96±2.16 vs 38.54±1.42 years, p<0.001). There was no significant association between the source of oocytes and gestational age at delivery (p=0.296), birth weight (p=0.836), admission to neonatal intensive care unit (ICU) (p=0.120), or maternal admission to adult ICU (p=0.767). Additionally, the origin of oocytes did not demonstrate any significant association with the risk of pre-eclampsia (p=0.357), gestational diabetes mellitus (p=0.187), premature rupture of membranes (p=0.996), uterine atony (p=0.996), placenta previa (p=0.393), oligohydramnios (p=0.393), or gestational hypertension (p=0.393)." CONCLUSION: An increase in obstetric and perinatal complications was not observed in pregnancies with DO compared to pregnancies with autologous oocytes in women undergoing ICSI without prior comorbidities. Further studies with larger sample sizes are required to validate our findings. OBJECTIVE (DO ICSI. .

Abstract Cleft lip and palate are the most common congenital malformations in the craniofacial region, occurring at a rate of 1:700 births in Brazil. These conditions lead to functional impacts on patients, such as changes in breathing, teeth, speech, chewing, swallowing and sucking. Treatment begins with primary surgeries, including lip and palate repair, which aim to reconstruct the soft tissues. Secondary alveolar bone grafting (SABG) reconstructs the bone defect in the cleft region, with the main goal of supplying bone tissue to the cleft region and restore the continuity of the alveolar process. Objective: To measure the changes in cross-sectional areas (CSAs) and nasal volume in patients and their impact on the nasal cavity (NC) in the two-month postoperative period (PO2M). Methodology: This study included 15 patients with complete unilateral cleft lip and palate (U/CLP) indicated for alveolar bone grafting (ABG). Cone beam computed tomography scans obtained prior to SABG and at PO2M were compared. Nasal volumes and CSAs were measured by marking the masks delimiting the nasal cavity on CT scans using Mimics™ software. Results: NC volumes (total, right and left sides) were statistically lower at PO2M in patients with left-sided UCLP. In right-sided UCLP, these volumes were only significant for the total NC and left NC. The CSAs of the internal nasal valve in both groups showed significantly lower values compared to the preoperative period (p≤0.05). Conclusion: In the short term, alveolar bone graft surgery reduces the volume of nasal cavities and the cross-sectional areas of the right and left internal nasal valve as a whole, not only the cleft area where the graft material was placed. 1700 1 700 1:70 Brazil breathing teeth speech chewing sucking surgeries repair tissues (SABG process Objective crosssectional cross sectional (CSAs (NC twomonth two month PO2M.

ABSTRACT Introduction: The Karnofsky Performance Status (KPS) is one of the most widely used tools for assessing the prognosis of oncology patients, providing an estimate of treatment efficiency and survival. Despite this, it is commonly used in free translations without validation. The objective of the present study was to perform the cross-cultural adaptation of the KPS instrument to Brazilian Portuguese (KPS-BR) through the stages of conceptual, semantic, operational, measurement, and functional equivalences. Methods: To assess consistency, we used Cronbach’s alpha and kappa coefficients. The Chi-square test was performed to evaluate the association between scores and the number of deaths. The relationship with survival and mortality was explored with Kaplan-Meier curves. Results: A total of 316 patients participated in the study. The internal consistency analysis resulted in a Cronbach’s alpha coefficient of 0.9265. For the inter-rater analysis, the correlation coefficient was 1, as was the kappa coefficient, indicating perfect agreement between observers. The correlation coefficient between the KPS-BR scale in the test-retest was 0.8631. We observed a 100% death rate at KPS-BR scale score 20 and a gradual decrease as the KPS-BR scale score increases up to KPS-BR 40 (p<0.0001). Estimation of survival using the Kaplan-Meier method demonstrated an association between KPS-BR scale scores and survival (p<0.0001). Conclusion: The KPS-BR scale showed reliability and validity for the prognostic assessment of cancer patients, demonstrating a correlation with survival.

RESUMO Introdução: O Karnofsky Performance Status (KPS) é um dos instrumentos mais utilizados para avaliação do prognóstico do paciente oncológico proporcionando a estimativa de eficiência do tratamento e sobrevida. Apesar disso, é comumente utilizado em traduções livres e sem validação. O objetivo do presente estudo foi realizar a adaptação transcultural do instrumento KPS para o português do Brasil (KPS-BR) em suas etapas de equivalências de conceito, semântica, operacional, mensuração e funcional. Métodos: Para avaliação da consistência utilizamos os coeficientes alfa de Cronbach e kappa. Foi realizado o teste Qui-quadrado para avaliar a associação das pontuações e o número de óbitos. A relação com o tempo de sobrevida e a mortalidade foi explorada com curvas de Kaplan-Meier. Resultados: Um total de 316 pacientes participaram do estudo. A análise de consistência interna resultou em coeficiente de confiabilidade alfa de Cronbach de 0,9265. Para análise inter-aferidor, o coeficiente de correlação foi de 1, assim como o coeficiente kappa, indicando uma concordância perfeita entre os observadores. O coeficiente de correlação entre a escala KPS-BR no teste-reteste foi de 0,8631. Observamos uma taxa de 100% de óbitos na pontuação 20 da escala KPS-BR e uma diminuição gradual à medida que a pontuação da escala KPS-BR aumenta até KPS-BR 40 (p<0,0001). A estimativa da sobrevida pelo método Kaplan-Meier mostrou uma associação entre as pontuações da escala KPS-BR e a sobrevida (p<0,0001). Conclusão: A escala KPS-BR apresentou confiabilidade e validade para a avaliação prognóstica de pacientes com câncer, mostrando associação com a sobrevida.

RESUMO: O presente trabalho avaliou o crescimento das espécies Mytella guyanensis e Mytella strigata em cordas suspensas na Costa de Manguezais de Macromarés da Amazônia. Os mexilhões foram cultivados na densidade de 840 ind. m-1 de corda, com a mesma altura de valva (mm) e peso vivo (g) para ambas as espécies. O experimento ocorreu inteiramente casualizado, com dois tratamentos e 15 repetições. Foram encontradas diferenças significativas quanto ao crescimento (altura da concha e peso vivo) entre as espécies (P>0,05). A taxa de crescimento diário foi maior para a M. guyanensis do que para M. strigata. Ao final do ciclo de cultivo, apenas 451 ± 46 (59,9%) indivíduos de M. guyanensis atingiram o tamanho comercial por metro de corda comparado a 670 ± 73 (89,3%) indivíduos de M. strigata. As taxas de sobrevivência foram semelhantes. A salinidade e a temperatura aumentaram progressivamente ao longo do experimento com a redução das chuvas e ficaram dentro da faixa considerada ideal para essas espécies. Em conclusão, o cultivo de ambas as espécies de mexilhões foi viável em condições estuarinas influenciadas pelas macromarés, com taxas de sobrevivência e crescimento diário satisfatórios (altura de valva e peso).

ABSTRACT: The present study evaluated the growth of the species Mytella guyanensis and Mytella strigata on ropes suspended in Amazon Macrotidal Mangrove Coast. The mussels were farmed at a density of 840 ind. m-1 of rope, with the same shell height (mm) and live weight (g) for both species. The experiment was entirely randomized, with two treatments and 15 repetitions. Significant differences were reported regarding the growth (shell height and live weight) between the species (P>0.05). The daily growth rate was greater for M. guyanensis than for M. strigata. At the end of the cultivation cycle, only 451 ± 46 (59.9%) of M. guyanensis individuals reached commercial size per meter of rope compared to 670 ± 73 (89.3%) of M. strigata individuals. Survival rates were similar. Salinity and temperature increased progressively throughout the experiment with the reduction in rainfall and were within the range considered ideal for these species. In conclusion, the farming of both species of mussels was viable under estuarine conditions influenced by macrotides, with satisfactory survival rates and daily growth (shell height and weight).

Abstract Wooden breast (WB) is a myopathy characterized by functional changes and excessive hardness in chicken fillets. Alcalase, a proteinase capable of hydrolyzing meat proteins, has been shown to improve protein functionality and promote meat tenderization. This study evaluated the application of alcalase in the preparation of cooked and salted chicken breast from WB chicken fillets. WB fillets were divided into two groups: an enzyme-treated and an untreated (control) group. Enzyme-treated fillets had lower pH values, total and soluble collagen contents, collagen/protein ratio, and shear force than control. No changes in color, chemical composition, or water-holding capacity compared between groups was observed. After 2 days of storage, enzyme-treated fillets had lower lipid oxidation and total color change. Alcalase hydrolysis of WB fillets improved the tenderness and nutritional value of the cooked and salted chicken meat product. This strategy shows promise for minimizing economic losses caused by the WB myopathy.

RESUMO Objetivo: Avaliar a eficácia do envio de mensagens de texto na melhora da adesão ao tratamento oclusivo da ambliopia. O objetivo secundário foi correlacionar as respostas dadas no questionário autorreportado e os resultados obtidos no tratamento (melhora da acuidade visual). Métodos: Ensaio clínico prospectivo, mascarado e randomizado. Os pais ou responsáveis legais dos pacientes no grupo intervenção receberam mensagens de texto para lembrar a importância dos oclusores. O grupo controle não recebeu mensagens. Na avaliação geral após 3 a 6 meses, os responsáveis responderam a um questionário autorreportado para avaliar a aderência ao tratamento. Resultados: Foram incluídos 34 pacientes com idade média de 5,35 anos; 20 eram do grupo intervenção. A população do estudo foi considerada 50% pouco aderente ao tratamento, 29% com aderência média e 21% com boa aderência, de acordo com resultado do questionário autorreportado. Não houve diferença significativa entre os grupos estudados. Quando comparada a relação entre a melhora da acuidade visual com o valor médio do questionário autorreportado, foi observada associação significativa da melhora com a adesão ao tratamento (p=0,03). Conclusão: Este estudo não mostrou melhora da aderência ao tratamento oclusivo com o envio de mensagens de texto, como tinha sido observado em estudos anteriores para outros tratamentos. Foi identificada uma relação estatisticamente significativa entre a melhora na acuidade visual e boa aderência terapêutica medida pelo questionário autorreportado. Isso permite recomendar o uso do questionário autorreportado como uma forma simples de mensurar aderência ao tratamento e auxiliar nas decisões sobre estratégias a serem adotadas na continuidade do seguimento do paciente.

ABSTRACT Objective: To evaluate the effectiveness of text messaging in improving adherence to occlusion therapy for amblyopia. The secondary objective was to correlate the responses given in a self-reporting questionnaire with treatment outcome (improvement in visual acuity). Methods: This is a prospective, randomized, blinded clinical trial. The patients’ parents or legal guardians in the intervention group received text messages reminding them of the importance of patching. The control group received no text messages. At final evaluation, after a period of three to six months, the patients’ parents or legal guardians answered a self-reporting questionnaire to evaluate adherence to treatment. Results: The study included 34 patients with an average age of 5.35 years, 20 in the intervention group and 14 in the control group. According to the results of the self-reporting questionnaire, 50% of the study population was considered as having low adherence to treatment, 29% as having medium adherence, and 21% as having good adherence. There was no significant difference between trial groups. The comparison between an improvement in visual acuity and the mean value obtained in the self-reporting questionnaire showed a significant association between this improvement and adherence to treatment (p=0.03). Conclusion: The present study did not find a correlation between text messaging and an improvement in adherence to occlusion therapy, as shown by previous studies for different treatments. A statistically significant association was identified between an improvement in visual acuity and a good therapeutic adherence, as measured by the self-reporting questionnaire. This finding allows us to recommend using a self-reporting questionnaire as a simple method to measure adherence to treatment and help decisions about therapeutic strategies to be adopted in the patient's continuing treatment.

Abstract Chagas disease (CD) is caused by the protozoan Trypanosoma cruzi and affects about six to seven million individuals worldwide. The distribution of cases is concentrated mainly throughout Latin America, especially in rural areas. This study aims to evaluate microRNAs (miRNAs) as indicators in CD diagnosis for possible contributions to its management. This is a literature review study, carried out in the PubMed, SciELO, Bireme Library, NCBI, Science Direct, and Embase databases, through which a total of 12 articles were included for qualitative analysis. The discussion of this review was based on the thematic axes regarding the modulation of T. cruzi in the immune system and the expression of miRNAs, their production and action, the modulation mechanism of host gene expression, how they act as biomarkers, the importance of miRNAs in the diagnosis of CD, and how their regulation occurs in Chronic Chagas Cardiomyopathy (CCC). Moreover, T. cruzi infection is associated with the downregulation of several miRNAs, which directly related to the findings of hypertrophy and fibrosis. When quantified, these could be used as consistent indicators for CD to support the diagnosis of patients with CD complications, as well as a possible therapeutic target. However, the need for clinical studies that evaluate the usefulness of this biomarker in humans is emphasized, considering that in the present study, only experimental in vitro studies were evaluated, reflecting a lack of studies with practical applicability.
