Abstract Background Treatment of atrial fibrillation (AF) with catheter ablation (CA) has evolved significantly. However, real-world data on long-term outcomes are limited, particularly in low- and middle-income countries. Objective This multicenter prospective cohort of consecutive patients aimed to evaluate the safety and efficacy of first-time CA for AF in Southern Brazil from 2009 to 2024. Methods The primary outcome was any atrial tachyarrhythmia (ATA) recurrence. Multivariable Cox proportional hazards model assessed independent predictors of recurrence. Results Among 1,043 patients (mean age 67.3 ± 11.3 years, 27.9% female), 75.5% had paroxysmal AF. At a median follow-up of 1.4 (1.0 - 3.4) years, 21.4% had ATA recurrence. Recurrence rates were 18.6% for paroxysmal and 29.8% for persistent AF, and 67.3% of events occurred within the first year after CA. Predictors of recurrence were persistent AF at baseline (hazard ratio [HR] 1.57, 95% confidence interval [CI] 1.15-2.13; p = 0.004), enlargement of left atrial diameter (HR 1.03, 95% CI 1.00-1.05; p = 0.033), and higher EHRA score of AF symptoms (HR 1.60, 95% CI 1.18-2.18; p = 0.003). Recurrence rates decreased over time according to the procedure’s calendar year, with a 9% relative reduction per consecutive year (HR 0.91; p < 0.001). There was a 2.1% rate of procedure-related adverse events. Conclusions In the largest cohort study of consecutive AF ablations in Latin America, predictors of ATA recurrence were related to later stages of AF. Complication and recurrence rates were comparable to those in high-income countries, underscoring the global applicability of CA for AF management.
Resumo Fundamento O tratamento da fibrilação atrial (FA) com ablação por cateter evoluiu significativamente. No entanto, dados do cenário clínico real em desfechos de longo prazo são limitados, particularmente em países de baixa e média renda. Objetivo Este estudo prospectivo, multicêntrico, do tipo coorte de pacientes consecutivos tem como objetivo avaliar a segurança da primeira ablação por cateter da FA na região sudeste do Brazil entre 2009 e 2024. Métodos O desfecho primário foi a recorrência de qualquer taquiarritmia atrial (TAA). O modelo de riscos proporcionais de Cox avaliou preditores independentes de recorrência. Resultados Entre 1043 pacientes (idade média 67,3 ± 11,3 anos, 27,9% mulheres), 75,5% apresentaram FA paroxística. Após um tempo mediano de acompanhamento de 1,4 (1,0 – 3,4) anos, 21,4% apresentaram recorrência de TAA. As taxas de recorrência foram de 18,6% para FA paroxística e de 29,8% para FA persistente; 67,3% dos eventos ocorreram no primeiro ano após a ablação por cateter. Preditores de recorrência foram FA persistente no basal [hazard ratio (HR) 1,57, Intervalo de Confiança (IC) 95% 1,15-2,13; p = 0,004), aumento do diâmetro atrial esquerdo (HR 1,03, IC95% 1,00-1,05; p = 0,033), e escore EHRA de sintomas de FA mais alto (HR 1,60, IC95% 1,18-2,18; p = 0,003). As taxas de recorrência diminuíram ao longo do tempo de acordo com o ano calendário do procedimento, com uma redução de 9% por ano consecutivo (HR 0,91; p < 0,001). Houve uma taxa de 2,1% de ocorrência de eventos adversos relacionados ao procedimento. Conclusão No maior estudo coorte de ablações consecutivas da FA da América Latina, preditores de recorrência de TAA se associaram com estágios mais avançados da FA. As taxas de complicação e de recorrência foram comparáveis às de países de alta renda, destacando a aplicabilidade global da ablação por cateter para o manejo da FA.

The rapid advance of nanotechnology has led to the proliferation of a wide range of water-soluble nanomaterials and therefore, a profound impact on the environment, underscoring the need to devise effective methods for isolating and confining these nanomaterials. This study presents the development of a highly effective system capable of removing and storing gold nanoparticles in solution using modified resins with different linking groups, such as tris(2-aminoethyl) amine, 3-mercaptopropionic acid, 11-mercaptoundecanoic acid, and L-cysteine. The catalytic properties of the resins functionalized with the thiol group containing gold nanoparticles were evaluated, using the reduction of the nitro compounds (3,5-dinitrosalicylic acid, 4-nitroguaiacol and 4-nitroaniline) as model reaction. Solid-phase organic synthesis was employed to prepare the modified resins and their interaction with gold nanoparticles was characterized using infrared spectroscopy, thermogravimetric analysis, field emission scanning electron microscopy-energy dispersive spectroscopy, and X-ray photoelectron spectroscopy. The removal capacity of the resins was evaluated using ultraviolet-visible optical emission spectroscopy and inductively coupled plasma techniques. Ultraviolet-visible technique was suitable to assess the catalytic properties of the functionalized resins containing gold nanoparticles. It was determined that the functionalized resins showed remarkable capacity for complex gold nanoparticles, removing them from the solution. The most significant removal was with 11-mercaptoundecanoic acid. watersoluble water soluble therefore environment groups tris2aminoethyl trisaminoethyl tris 2 aminoethyl tris(2-aminoethyl amine 3mercaptopropionic mercaptopropionic 3 acid 11mercaptoundecanoic mercaptoundecanoic 11 Lcysteine.

Lisdexamfetamine is a prodrug that is converted to d-amphetamine in the body, mainly used to treat attention deficit hyperactivity disorder in children and adults. Its mechanism involves the enhancement of neurotransmitters such as norepinephrine and dopamine, which are critical for attention and behavioral regulation. With the upcoming patent expiration of Vyvanse®, bioanalytical methods for the quantification of lisdexamfetamine in plasma are needed for use in pharmacokinetic studies. In this work, we developed and validated a sensitive bioanalytical method using liquid chromatography-tandem mass spectrometry (LC-MS/MS) for lisdexamfetamine quantification in human plasma. The method developed was performed for 4 min per sample and using the concentration range of 0.3-100 ng mL-1. Intra-batch, inter-batch and instrument reproducibility, the precision was lower than 10%. The results demonstrated that the method is rapid, sensitive, robust, and suitable for pharmacokinetic studies. damphetamine d amphetamine body adults dopamine regulation Vyvanse Vyvanse® studies work chromatographytandem chromatography tandem LCMS/MS LCMSMS LC MS/MS MS (LC-MS/MS 0.3100 03100 0.3 100 0 3 0.3-10 mL1. mL1 mL 1. 1 mL-1 Intrabatch, Intrabatch Intra batch, batch Intra-batch interbatch inter reproducibility 10 10% rapid robust LCMS MSMS 3100 0.310 0310 03 0. 0.3-1 mL- 310 0.31 031 0.3- 31

Abstract Objective: To describe the changes in alcohol and drug use by Brazilian adolescents during the COVID-19 pandemic (April-August 2021), and to analyze the relationship between alcohol use changes and psychiatric symptomatology. Methods: A secondary analysis with a longitudinal approach was performed with data from a cluster-randomized controlled trial, conductedin73publicmiddleschoolsinthreeBrazilian cities, to evaluate the effectiveness of a drug use prevention program. The sample included 535 students (61% girls; Mage = 15.2 years). Data were collected pre-intervention (February-March 2019), after 9 months (November-December 2019), and after 26 months (April-August 2021), when the students were in their first year of high school. The authors analyzed drug use prevalence (alcohol, binge drinking, tobacco, inhalants, marijuana, cocaine, and crack) in a lifetime, past year, and past month periods, and the association between alcohol use change subsamples with psychiatric symptoms. Logistic regressions were adjusted by sex, age, socioeconomic status, city, and group (control and intervention). Results: The present findings suggest that the COVID-19 pandemic led to a decrease in past-year substance use and in past-month substance use frequency, despite the gradually increased (but decelerating) prevalence of lifetime use. However, some adolescents initiated, maintained, or increased the frequency of their alcohol use. Mainly, they were more likely to present behavioral problems, as well as symptoms of inattentive hyperactivity, and peer and emotional problems. Conclusions: Despite the extensive decline in substance use during the pandemic period, these results suggest an association between previous mental health conditions and behavioral risk factors, leading to increased alcohol consumption and behavioral disorders manifestations.

RESUMEN Reportamos el caso de un hombre de 82 años residente de Iquitos, región amazónica del Perú, con una historia de tres meses de lesiones cutáneas dolorosas de leves a moderadas en la extremidad inferior derecha. El examen clínico reveló cuatro tumores en la tibia derecha, que exhibían crecimiento exofítico, apariencia verrugosa y ulceración. Se observaron dos nódulos subcutáneos. Se observó linfadenopatía inguinal agrandada. El examen histopatológico reveló un diagnóstico de melanoma. Este caso enfatiza la necesidad de una vigilancia integral y multidisciplinaria en regiones con datos limitados sobre melanoma que conducen a un subdiagnóstico de esta malignidad. Además, destaca la importancia de la prevención primaria como la protección solar en zonas tropicales para prevenir el melanoma cutáneo, abogando por aumentar la concienciación y las medidas preventivas.
ABSTRACT We report an 82-year-old male from Iquitos, Amazon region of Peru, with a three-month history of mild-to-moderate painful skin lesions on the right lower limb. The clinical examination revealed four tumors of the right shin, exhibiting exophytic growth, verrucose appearance, and ulceration. Two subcutaneous nodules were noted. Enlarged inguinal lymphadenopathy was observed. The histopathological examination revealed a diagnosis of melanoma. This case emphasizes the need for comprehensive and multidisciplinary surveillance in regions with limited melanoma data leading to a subdiagnosis of this malignancy. Also, it highlights the importance of primary prevention such as sun protection in tropical areas to prevent cutaneous melanoma, advocating for increasing awareness and preventive measures.

Hansen & Wunderlin (Apocynaceae) Lugar de estudio y fechas: Mérida, Yucatán, México, 2019 y 2020. Métodos: La floración se indujo exponiendo las plantas a temperaturas superiores a 32 °C. Las muestras de tejido vegetal se colectaron antes de la inducción de la floración y en plena floración, y se extrajeron con metanol. El análisis por Cromatografía de Gases-Espectrometría de Masas de la fracción soluble en diclorometano del extracto crudo permitió la detección y cuantificación de urechitol A. Resultados: La floración de P. andrieuxii tiene una influencia positiva en la producción de urechitol A en la raíz de la planta, observándose aumentos en el contenido del tri-nor-sesquiterpeno desde un mínimo de 43 hasta un máximo de 91 veces durante la floración de las plantas, tanto en plantas transformadas como silvestres. Conclusiones: P. andrieuxii percibe a las altas temperaturas como una señal ambiental importante para florecer; la floración influencia positivamente la producción de urechitol A en la raíz; la producción del tri-nor-sesquiterpeno es controlada por la planta.
Abstract Background: Pentalinon andrieuxii, is a medicinal plant used in Mayan folk medicine against leishmaniosis. It is an important source of terpenoids whose biosynthesis has been reported to be influenced by the ontogeny of the plant. Hypotheses: Flowering positively influences the production of urechitol A in Pentalinon andrieuxii. Studied species: Pentalinon andrieuxii (Müll. Arg.) B.F. Hansen & Wunderlin (Apocynaceae) Study site and dates: Mérida, Yucatán, Mexico, 2019 and 2020. Methods: Flowering was induced by exposing plants to temperatures above 32 °C. Plant tissue samples were collected before flowering induction and at full bloom and extracted with methanol. Analyses of the dichloromethane-soluble fraction of the crude extract by Gas Chromatography-Mass Spectrometry allowed the detection and quantification of urechitol A. Results: Flowering stage of P. andrieuxii has a positive influence on the production of urechitol A in the root of the plant, with the contents of the tri-nor-sesquiterpene increasing from a minimum of 43 to a maximum of 91 times during the flowering stage of plants, both transformed and wild type. Conclusions: P. andrieuxii perceives high temperatures as an important environmental cue to flower; flowering positively influences the production of urechitol A in the roots of the plant; production of the tri-nor-sesquiterpene is controlled by the plant.

Resumen Austrocylindropuntia pachypus (K.Schum.) Backeb. es un cactus endémico de Perú, cuya distribución conocida estaba restringida a las vertientes occidentales de La Libertad, Áncash y Lima. En base a expediciones botánicas por las estribaciones andinas de Ica, en este trabajo reportamos nuevas localidades con pequeñas poblaciones, lo que amplía en más de 260 km al sur la distribución conocida de A. pachypus. Además, en base a 42 registros georreferenciados, se amplía la información sobre sus localidades, poblaciones, distribución potencial, hábitats, amenazas y estado de conservación. El modelo de distribución potencial mostró altos niveles predictivos o de idoneidad con valores de AUC = 0.96 en base a siete variables climáticas, siendo Bio17, Bio2 y Bio7 las variables con mayor contribución; mostrando a Lambayeque, La Libertad, Áncash, Lima, Ica y Huancavelica los departamentos con mayores valores de idoneidad. Las poblaciones con mayor concentración de individuos, pero que a su vez se encuentran seriamente perturbadas por actividades antropogénicas, son las de los valles del río Chillón (Santa Rosa de Quives, Canta) y Rímac (Santa Eulalia, Huarochirí) en Lima. Asimismo, se estima que cerca del 70% de las poblaciones de A. pachypus se encuentran amenazadas por derechos mineros, extracción de hidrocarburos, sobrepastoreo y expansión urbana o agrícola, incrementando la fragmentación de sus hábitats, por lo que se propone categorizar a este cactus endémico como En Peligro (EN).
Abstract Austrocylindropuntia pachypus (K.Schum.) Backeb. is an endemic cactus of Peru, whose known distribution was restricted to the western slopes of La Libertad, Áncash, and Lima. Based on botanical expeditions along the Andean foothills of Ica, this study reports new localities with small populations, thereby extending the known distribution of A. pachypus by over 260 km to the south. Additionally, based on 42 georeferenced records, information on its localities, populations, potential distribution, habitats, threats, and conservation status is expanded. The potential distribution model exhibited high predictive or suitability levels with AUC values of 0.96 based on seven climatic variables, with Bio17, Bio2, and Bio7 being the most contributory variables; Lambayeque, La Libertad, Áncash, Lima, Ica, and Huancavelica demonstrated the highest suitability values. Populations with the highest concentration of individuals, yet significantly disturbed by anthropogenic activities, are those in the valleys of the Chillón River (Santa Rosa de Quives, Canta) and Rímac River (Santa Eulalia, Huarochirí) in Lima. Furthermore, it is estimated that approximately 70% of A. pachypus populations are threatened by mining rights, hydrocarbon extraction, overgrazing, and urban or agricultural expansion, exacerbating habitat fragmentation. Hence, it is proposed to categorize this endemic cactus as Endangered (EN).

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

Abstract This work presents the development of a refractive index sensing methodology for measuring carbon dioxide concentrations, considering the effect of temperature environment. We propose and demonstrate, using simulations, the use of tapered and coated Long Period Gratings as a way to enhance the refractive index sensitivity. In addition, artificial neural networks were used to improve the estimation of carbon dioxide concentration, considering the crosssensitivity effect with temperature. concentrations environment demonstrate simulations sensitivity addition concentration

ABSTRACT Objective: Patients with pediatric differentiated thyroid carcinoma (DTC) treated with radioiodine (RAI) therapy may experience long-term side effects, such as gonadal dysfunction. Therefore, it is crucial to understand the impact of this therapy on ovarian reserve and future pregnancy rates. Subjects and methods: Retrospective analysis of 64 female DTC survivors of childbearing age to assess the risk of infertility due to RAI performed before the age of 19 years. Results: Thirty-two out of the 64 DTC survivors had a history of at least one pregnancy during follow-up. No significant differences were observed between the cumulative RAI activity, treatment regimens (multiple versus single RAI treatment), age at first treatment, or presence of lymph node or distant metastases. Notably, the group without a history of pregnancy had a younger age at the time of diagnosis and larger tumors. Age at first pregnancy was slightly higher than that in the general population, but no increase in negative maternal or fetal outcomes was observed. Conclusions: The results of this study show little observational evidence suggesting important adverse effects of RAI on fertility or pregnancy outcomes among female survivors of childhood DTC. Still, studies including larger populations are warranted. Objective (DTC (RAI longterm long term dysfunction Therefore rates methods 6 1 years Results Thirtytwo Thirty two followup. followup follow up. up follow-up activity multiple , treatment) metastases Notably tumors population Conclusions Still warranted

It is essential to diversity energy sources for ensuring sustainability. While hydrogen is considered a promising energy storage medium, its potential hinges on the development of efficient photocatalysts for green production. In addressing this challenge, we evaluated the performance of a heterojunction system composed of non-stoichiometric molybdenum oxides (MoO3−x) and cadmium sulfide (CdS) quantum dots (QDs) for water splitting. MoO3−x were synthesized via gamma irradiation of the MoO3 in the presence of formic acid (FA), while CdS-MPA QDs were electrosynthesized. The heterojunction was formed through adsorption. The structural and electronic characterization revealed a progressive transformation from MoO3 to MoO3−x and MoO3−x/CdS-MPA QDs, demonstrating enhanced water-splitting performance. Upon evaluation, the study revealed a charge transfer mechanism, highlighting the significance of relative band positions between MoO3−x and CdS-MPA QDs in promoting eco-friendly hydrogen evolution and methanol processing. Thus, we suggest that the synergism between MoO3−x and CdS-MPA QDs semiconductors makes the heterojunction system a promising solution for photocatalytic production of hydrogen and oxygen. sustainability medium challenge nonstoichiometric non stoichiometric MoO3x MoOx x MoO (MoO3−x CdS (CdS (QDs splitting FA, FA , (FA) CdSMPA MPA electrosynthesized adsorption MoO3−x/CdSMPA MoO3xCdSMPA MoOxCdSMPA MoO3−x/CdS watersplitting evaluation mechanism ecofriendly eco friendly processing Thus oxygen (FA xCdSMPA MoO3xCdS MoOxCdS xCdS
