Abstract Entecavir is an inhibitor of hepatitis B virus (HBV) DNA synthesis that has been widely prescribed in the treatment of chronic infections caused by the virus. Production of generic ETV drugs is an ongoing global endeavor, with particular significance for developing countries that rely on importing the expensive reference drug. ETV-excipient compatibility studies were conducted with the declared inputs in solid pharmaceutical formulations on the market through thermal analysis and HPLC techniques. Thermal analyses by TGA and DTA indicated compatibility of entecavir with the excipients microcrystalline cellulose, crospovidone, titanium dioxide, magnesium stearate, hypromellose, polyethylene glycol and povidone; this was confirmed via HPLC. Lactose monohydrate proved to be incompatible with ETV in thermal and chromatographic assays. The thermal analysis of marketed solid dosage forms revealed a predominance of the lactose monohydrate profile at the expense of ETV and other inputs in the TGA and DTA curves, due to its high content in the formulations; this makes the evidence of ETV-lactose chemical interaction even more important. Compatibility tests by HPLC showed no chemical interaction of ETV with the excipient mannitol, a soluble diluent proposed as a replacement for lactose monohydrate, with the same function in the formulation.

Plants of the genus Crotalaria are known for their antagonistic effect against nematodes. It has been found that pyrrolizidine alkaloids are the main metabolites involved in such antagonistic activity. Aiming at obtaining extracts with higher alkaloid content and enhanced potential for use as bionematicides, we investigated the chemical composition and nematicidal activity of extracts obtained from Crotalaria juncea and Crotalaria ochroleuca cultivated in vitro through micropropagation. Remarkably, extracts from the callus of C. ochroleuca (lethal concentration of 95% (LC95) = 157.7 μg mL-1) and C. juncea (LC95 = 189.9 μg mL-1) exhibited high toxicity against Meloidogyne javanica. The ultra performance liquid chromatography coupled to quadrupole time-of-flight with high mass spectrometry (UPLC-QTOF-MSE) analysis revealed the presence of pyrrolizidine alkaloids, flavones, flavone glycosides, and isoflavones. These findings highlight the potential of tissue culture to obtain extracts from Crotalaria species compared to conventionally cultivated plants and provide a higher concentration of metabolites with nematicidal effects, paving the way for sustainable agriculture.

Abstract Belonging to the Alismataceae family, Echinodorus macrophyllus, known in Brazil as “chapéu de couro”, is popular in the food industry, where it is used in teas and infusions. The objective of this study was to evaluate the active chemical compounds in the powder of E. macrophyllus leaves extracted by two different methods (Soxhlet [SXT] and ultrasound-assisted extraction [UAE]), quantify the total phenolic compound (TPC) and total flavonoid (TFC) content, and evaluate the antioxidant potential and larvicidal activity. The SXT extraction was the most efficient (6.05% yield). Analysis by thin-layer chromatography (TLC) and high-performance liquid chromatography with a diode array detector (HPLC-DAD) evidenced the presence of cinnamic acid derivatives, flavones, and flavanones in the extracts. The TPC was higher in the SXT extract (7.71±0.05 µg GAE/mL). However, there was no significant difference in TFC. The SXT extract exhibited greater antioxidant potential according to the ferric reducing antioxidant power (FRAP) method (IC50=3.37±0.45 µg/mL), while the UAE extract showed higher activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH) (IC50=42.16±5.79 µg/mL). Both extracts were nontoxic to Artemia salina, suggesting the potential health benefits of this plant, which is rich in phenolic compounds and diverse pharmacological properties.

This study evaluated the potential of naphthoxazoles derived from lapachol as fluorescent deoxyribonucleic acid (DNA) probes. We synthesized three 2-substituted naphthoxazoles: one with a phenyl group (LOX1), and two with 2-hydroxyphenyl (LOX2) and 4-fluorophenyl (LOX3) groups, respectively. The compounds were synthesized using the Debus-Radziszewski reaction between the lapachol and aldehydes. The quantum yield (Φf) was determined using the classical relative method with 4’,6-diamidino-2-phenylindole (DAPI) as the standard, and the fluorescence lifetime (τf) was measured with a lifetime fluorescence spectrometer. The naphthoxazoles exhibited low fluorescence emission and consequently low values of Φf in their free form, demonstrating behavior similar to that of DAPI. These compounds displayed notably large Stokes shifts (approximately 340 nm) and the τf in the nanosecond range. DNA binding studies were conducted by monitoring changes in the absorption properties of naphthoxazoles in the absence and presence of calf thymus DNA at different concentrations. The results indicated that naphthoxazoles interacted with DNA through groove binding. LOX2 exhibited a binding constant (Kb) of 2.70 × 104 M-1, indicating strong binding to the biomolecule. These findings underscore the potential of LOX1, LOX2, and LOX3 as candidates for use as fluorescent DNA probes.

ABSTRACT The aim of this study was to evaluate development in the following tree species: Acacia mangium Willd, Anadenanthera colubrina var. cebil (Griseb.) Altschu, Casuarina equisetifolia L. ex J. R. Forst. & G. Forst, Handroanthus impetiginosus (Mart. Ex DC.) Mattos, and Colubrina glandulosa subsp. reitzii (M.C.Johnst.) Borhidi under two water regimes in the Irrigated Perimeter of Baixo Acaraú, in the state of Ceará. The experiment was conducted over seven years, with the factors represented by water regimes, species and periods in an arrangement of split-split plots in a completely randomised design repeated over time with four replications of two plants each. The response variables were total height, diameter at breast height, volume, absolute growth rate in height and diameter, and current and average annual increase in volume. After seven years, the species Acacia mangium, Casuarina equisetifolia, Handroanthus impetiginosus, Anadenanthera colubrina and Colubrina glandulosa presented the following respective mean volumes: 0.62, 0.47, 0.45, 0.31 and 0.29 m3 irrespective of the water regime. Despite a reduction in the growth rates of the species during each period, they remained positive, and growth did not stop. The mean values for volume confirm that the species showed similar growth for the water regimes under study. An irrigated regime of up to one year is therefore suggested for cultivating these species in the Irrigated Perimeter of Baixo Acaraú, Ceará. Willd var Griseb. Griseb (Griseb.

RESUMO O processo de secagem é de suma importância para a manutenção da qualidade das sementes, onde a temperatura de condução deste processo exerce influência direta sobre a germinação e vigor, sobretudo para as espécies olerícolas que são colhidas com alto teor de água. O objetivo desta pesquisa foi determinar e modelar as curvas de secagem de sementes de jiló (cultivar Tinguá-verde-claro) nas temperaturas de 35, 38, 41 e 44 ºC, bem como avaliar a qualidade fisiológica das sementes após a secagem. Foi utilizado o delineamento inteiramente casualizado, sendo quatro temperaturas de secagem (35, 38, 41 e 44 ºC) com quatro repetições. Nove modelos matemáticos foram ajustados por meio de análise de regressão não linear pelo método de Gauss-Newton, e o grau de ajuste foi avaliado com base na magnitude do coeficiente de determinação (R2), teste qui-quadrado (χ2), erro médio relativo (P) e erro médio estimado (SE). A qualidade das sementes foi avaliada pelo teste de germinação (G), condutividade elétrica (CE) e envelhecimento acelerado (EA). O modelo ‘Midilli Modificado’ é o que melhor representa as curvas de secagem das sementes de jiló nas temperaturas estudadas. Sementes com maior germinação e vigor, ou seja, com menores valores de CE e maiores taxas de germinação após EA, são alcançadas através da secagem a 35 e 38 ºC. vigor água cultivar Tinguáverdeclaro Tinguá verde claro Tinguá-verde-claro 4 ºC casualizado (35 repetições GaussNewton, GaussNewton Gauss Newton, Newton Gauss-Newton R2, R2 R , (R2) quiquadrado qui quadrado χ2, χ2 χ (χ2) P (P SE.

ABSTRACT The drying process is paramount for maintaining seed quality, where the temperature during this process directly influences germination and vigor, especially for vegetable species harvested with high moisture content. This research aimed to determine and model the drying curves of S. aethiopicum (cultivar Tinguá-verde-claro) seeds at temperatures of 35, 38, 41, and 44 ºC, as well as to evaluate the physiological quality of the seeds after drying. A completely randomized design was used, with four drying temperatures (35, 38, 41, and 44 ºC) and four replicates. Nine mathematical models were fitted using the non-linear regression analysis by the Gauss-Newton method, and the goodness of fit was assessed based on the magnitude of the coefficient of determination (R2), chi-square test (χ2), relative mean error (P), and estimated mean error (SE). Seed quality was evaluated by germination test (G), electrical conductivity (EC), and accelerated aging (AA). The Modified Midilli model best represents the drying curves of S. aethiopicum seeds at the studied temperatures. Seeds with higher germination and vigor, meaning lower electrical conductivity values and higher germination rates after accelerated aging, are achieved through drying at 35 and 38 ºC. vigor content S cultivar Tinguáverdeclaro Tinguá verde claro Tinguá-verde-claro 41 4 ºC used (35 replicates nonlinear non linear GaussNewton Gauss Newton method R2, R2 R , (R2) chisquare chi square χ2, χ2 χ (χ2) P, P (P) SE.

Abstract Objective: To evaluate exclusive breastfeeding at discharge and hospital length-of-stay in pre-term infants undergoing or not the Kangaroo-Mother Care Method (KMC). Methods: A retrospective cohort study was conducted including preterm infants < 1800 g admitted to the neonatal unit of a KMC reference center. The infants were grouped into the KMC group and the non-KMC group. Multiple logistic and Poisson regressions were performed to evaluate the association between the KMC and two outcomes, exclusive breastfeeding at discharge, and hospital length-of-stay, adjusted for potential confounders. Results: 115 mother-infant dyads were included, 78 in the KMC group and 37 in the non-KMC group. In the bivariate analysis, the KMC group had a lower prevalence of maternal adverse conditions (6% vs. 32%, p < 0.001), a higher number of prenatal visits (median 6 vs. 3.5, p < 0.001), higher gestational ages (median 32 vs. 31 weeks, p < 0.05), higher birth weights (median 1530 vs. 1365 g, p < 0.01), a lower prevalence of necrotizing enterocolitis (3.8% vs. 16.2%, p < 0.05), parenteral nutrition (50% vs. 73%, p < 0.05), and deep vascular access (49.7% vs. 78.4%, p < 0.01), a higher prevalence of exclusive breastfeeding (65% vs. 8%, p < 0.001) and a shorter length of hospital stay (median 28 vs. 42 days, p < 0.001). In the multiple regression analysis, the KMC group was 23 times more likely to be exclusively breastfed at discharge (OR = 23.1; 95% CI = 4,85–109,93) and had a 19% reduction in the hospital length-of-stay (IDR = 0.81; 95% CI = 0.76–0.86) compared to the non-KMC group. Conclusions: The KMC is associated with better short-term neonatal outcomes and should be encouraged in all Brazilian maternity hospitals.

Abstract Objective: To investigate the effectiveness of linezolid and vancomycin for the treatment of nosocomial infections in children under 12 years old. Data sources: This is a systematic review in which five randomized clinical trials about the effectiveness of linezolid and vancomycin, involving a total of 429 children with nosocomial infections, were evaluated. They were searched in scientific databases: PubMed, Bvs, and SciELO. Summary of findings: The main nosocomial infections that affected children were bacteremia, skin, and soft tissue infections followed by nosocomial pneumonia. Most infections were caused by Gram-positive bacteria, which all studies showed infections caused by Staphylococcus aureus, with methicillin-resistant S. aureus (MRSA) and methicillin-resistant coagulase-negative staphylococci strains being isolated. Both linezolid and vancomycin showed high therapeutic efficacy against different types of nosocomial infections, ranging from 84.4% to 94% for linezolid and 76.9% to 90% for vancomycin. Patients receiving linezolid had lower rates of rash and red man syndrome compared to those receiving vancomycin. However, despite the adverse reactions, antimicrobials can be safely administered to children to treat nosocomial infections caused by resistant Gram-positive bacteria. Conclusion: Both linezolid and vancomycin showed good efficacy in the treatment of bacterial infections caused by resistant Gram-positive bacteria in hospitalized children. However, linezolid stands out regarding its pharmacological safety. Importantly, to strengthen this conclusion, further clinical trials are needed to provide additional evidence.

Abstract Introduction: Cardiovascular disease is an important cause of death among patients with chronic kidney disease (CKD). Valve calcification is a predictor of cardiovascular mortality and coronary artery disease. Objective: To assess heart valve disease frequency, associated factors, and progression in CKD patients. Methods: We conducted a retrospective study on 291 CKD patients at Hospital das Clínicas de Pernambuco. Inclusion criteria were age ≥ 18 with CKD and valve disease, while those on conservative management or with missing data were excluded. Clinical and laboratory variables were compared, and patients were categorized by dialysis duration (<5 years; 5–10 years; >10 years). Statistical tests, including chi-square, Fisher’s exact, ANOVA, and Kruskal-Wallis, were employed as needed. Simple and multivariate binary regression models were used to analyze valve disease associations with dialysis duration. Significance was defined as p < 0.05. Results: Mitral valve disease was present in 82.5% (240) of patients, followed by aortic valve disease (65.6%; 86). Over time, 106 (36.4%) patients developed valve disease. No significant association was found between aortic, pulmonary, mitral, or tricuspid valve disease and dialysis duration. Secondary hyperparathyroidism was the sole statistically significant factor for mitral valve disease in the regression model (OR 2.59 [95% CI: 1.09–6.18]; p = 0.031). Conclusion: CKD patients on renal replacement therapy exhibit a high frequency of valve disease, particularly mitral and aortic valve disease. However, no link was established between dialysis duration and valve disease occurrence or progression. Introduction CKD. .

ABSTRACT Purpouse: One of the many artificial intelligence based tools that has gained popularity is the Chat-Generative Pre-Trained Transformer (ChatGPT). Due to its popularity, incorrect information provided by ChatGPT will have an impact on patient misinformation. Furthermore, it may cause misconduct as ChatGPT can mislead physicians on the decision-making pathway. Therefore, the aim of this study is to evaluate the accuracy and reproducibility of ChatGPT answers regarding urological diagnoses. Materials and Methods: ChatGPT 3.5 version was used. The questions asked for the program involved Primary Megaureter (pMU), Enuresis and Vesicoureteral Reflux (VUR). There were three queries for each topic. The queries were inserted twice, and both responses were recorded to examine the reproducibility of ChatGPT's answers. Afterwards, both answers were combined. Finally, those rwere evaluated qualitatively by a board of three specialists. A descriptive analysis was performed. Results and Conclusion: ChatGPT simulated general knowledge on the researched topics. Regarding Enuresis, the provided definition was partially correct, as the generic response allowed for misinterpretation. For VUR, the response was considered appropriate. For pMU it was partially correct, lacking essential aspects of its definition such as the diameter of the dilatation of the ureter. Unnecessary exams were suggested, for Enuresis and pMU. Regarding the treatment of the conditions mentioned, it specified treatments for Enuresis that are ineffective, such as bladder training. Therefore, ChatGPT responses present a combination of accurate information, but also incomplete, ambiguous and, occasionally, misleading details.

ABSTRACT Objectives: To analyze brain death (BD) notifications received by Central de Transplantes (CET) in the state of Roraima (RR) from 2017 to 2021. Methods: This is a cross-sectional, quantitative, and observational study, where all notifications received by CET from 2017 to 2021 were analyzed, resulting in 120 patients from health the following centers: Hospital Geral de Roraima (HGR), Hospital Confederação Nacional das Cooperativas Médicas (UNIMED), Hospital da Criança Santo Antônio (HCSA), Hospital das Clínicas (HC), and Hospital Lotty Íris (HLI). The data were collected from the center’s data management system and passed on to the collection form developed by the researcher. Results: This study analyzed 119 notifications after excluding one due to conflicting data. There was a predominance of males (58%), with traumatic brain injury being the most frequent cause of BD. Six organ harvestings were carried out, all at the HGR. This study found no significant associations between organ procurement and sex, age, place of hospitalization, and year. Conclusion: There are considerable challenges concerning organ donation in RR, with a low uptake rate over five years. Only the HGR successfully carried out organ harvesting, while other reporting hospitals were unsuccessful. Improvements are needed, highlighting the importance of more studies for a more in-depth data analysis.

RESUMO Objetivos: Analisar as notificações de morte encefálica (ME) recebidas pela Central de Transplantes (CET) do estado de Roraima (RR) de 2017 a 2021. Métodos: Trata-se de estudo transversal, quantitativo e observacional no qual foram analisadas todas as notificações recebidas pela CET no período de 2017 a 2021, resultando em 120 pacientes, dos seguintes centros de saúde: Hospital Geral de Roraima (HGR), Hospital Confederação Nacional das Cooperativas Médicas (UNIMED), Hospital da Criança Santo Antônio (HCSA), Hospital das Clínicas (HC) e Hospital Lotty Íris (HLI). Os dados foram coletados do sistema de gerenciamento de dados da central e repassados para a ficha de coleta desenvolvida pela pesquisadora. Resultados: Este estudo analisou 119 notificações após a exclusão de uma devido a dados conflitantes. Houve predominância do sexo masculino (58%), com trauma cranioencefálico sendo a causa mais frequente de ME. Ao todo, foram realizadas seis captações de órgãos, todas no HGR. Este estudo não encontrou associações significativas entre a captação de órgãos e sexo, idade, local de internação e ano. Conclusão: Há grandes desafios em relação à doação de órgãos em RR, com uma taxa de captação baixa ao longo de 5 anos. Apenas o HGR obteve sucesso em realizar captações de órgãos, diferentemente de outros hospitais notificadores. São necessárias melhorias, destacando a importância de se realizarem mais estudos para uma análise mais aprofundada dos dados.

Abstract Biodiesel serves as a biodegradable, non-toxic, and renewable fuel option that offers an alternative to traditional fossil fuels. This study aimed to examine the impact of elevating biodiesel content to 20% and 50% within regular diesel, with a focus on comprehending how these fuel mixtures influence variations in soot composition using Raman spectroscopy. The soot samples under analysis originated from commercial S10 diesel, as well as fuel blends containing 20% and 50% portions of sunflower and macaúba biodiesel, whereupon the use of this methodology for these fuels characterizes the novelty of this work. The outcomes derived from analyzing the soot samples revealed distinct characteristics in the G, D1, D3, and D4 bands. The ratio between the intensities of these D and G bands is closely indicative of the soot's structure. Consequently, this ratio was analyzed in this investigation to assess the effects of biodiesel concentration and engine rotation speed on soot characteristics. The conclusions found in this study indicated that there was minimal variation in the spectral characteristics of the soot samples across the different fuels and varying engine speeds. As a result, it is inferred that increasing the proportion of biodiesel in commercial diesel S10 did not have a significant impact on the structural composition of soot. biodegradable nontoxic, nontoxic non toxic, toxic non-toxic 20 50 spectroscopy S S1 work D1 D3 soots s structure Consequently speeds result 2 5

Generalized anxiety disorder is a highly prevalent mental disorder. Previous data indicate that more than 18 million Brazilians suffer from this condition. Traditionally, generalized anxiety disorder has been considered a mild mental health disorder, despite its links to lower life expectancy, cardiovascular disease, and suicide. The aim of this article is to combine elements of systematic and critical reviews to produce a synthesis of the best evidence about generalized anxiety disorder treatment. Systematic reviews, meta-analyses, and randomized controlled trials were included. The descriptor used in the search was “generalized anxiety disorder,” which resulted in 4,860 articles and seven other studies, of which 59 were selected. Antidepressants and benzodiazepines were indicated, as was pregabalin, and atypical antipsychotics, such as quetiapine, have been studied. Individual cognitive behavior therapy (third wave) has proven effective. There is extensive literature on many effective treatments for generalized anxiety disorder. The present review summarizes the therapeutic possibilities, emphasizing those available in Brazil. Further studies are needed to compare other available medications, assess psychotherapies and new treatments in greater depth, as well as to assess the ideal duration of therapy.
