We report a facile hydrothermal method for the synthesis of niobium pentoxide (Nb2O5) under two different temperatures, 120 °C (Nb2O5-120) and 150 °C (Nb2O5-150). The obtained materials were characterized by structural, optical and morphological techniques. Also, the photocatalytic properties of the Nb2O5 samples were evaluated in two reactions under ultraviolet (UVC) irradiation: degradation of methylene blue (MB) and indigo carmine (IC) dyes; and esterification of free fatty acids (FFA) present in waste cooking oil (WCO). The Nb2O5 was formed at different temperatures of synthesis, and the increase in temperature did not cause significant changes in the structural and optical characteristics, but resulted in an increased surface area of the synthesized materials. Both synthesized materials showed excellent efficiency for dye photodegradation. The sample Nb2O5-150 presented the best performance for the MB photodegradation, with almost 85% of the removal efficiency. In this case, the adsorption of MB molecules on the surface of the material was high due to the favorable electrostatic interaction and also because of its high surface area. For the IC photodegradation, the adsorption was insignificant, and both samples presented approximately 100% of the removal efficiency. These materials were also promising for the reduction of free fat acids in waste oil by photoesterification. NbO Nb O (Nb2O5 12 C Nb2O5120 (Nb2O5-120 15 Nb2O5150. Nb2O5150 .

RESUMO RACIONAL: A incidência do câncer de esôfago é elevada em algumas regiões e o tratamento cirúrgico requer centros de referência com alto volume para viabilizar a cirurgia. OBJETIVOS: Avaliar os pacientes submetidos à esofagectomia minimamente invasiva, por toracoscopia na posição prona, para o tratamento do câncer de esôfago e conhecer a experiência adquirida ao longo do tempo em nosso serviço após a introdução desta técnica. MÉTODOS: De janeiro de 2012 a agosto de 2021, foram analisados retrospectivamente todos os pacientes submetidos à esofagectomia minimamente invasiva para câncer de esôfago. Para avaliar os fatores associados aos desfechos predefinidos de fístula, pneumonia e óbito intra-hospitalar, realizamos análises de regressão logística univariada e multivariada considerando a idade como fator importante. RESULTADOS: Foram estudados 66 pacientes, com idade média de 59,5 anos. O tipo histológico mais frequente foi carcinoma espinocelular (81,8%). A incidência de pneumonia pós-operatória e fístula foi de 38% e 33,3%, respectivamente. Oito pacientes morreram durante este período. A idade do paciente, os estágios T e N, o ano da realização do procedimento e o desenvolvimento de pneumonia pós-operatória foram fatores que influenciaram o óbito. Houve uma redução de 24% na chance de mortalidade, ano a ano, associada à curva de aprendizado do nosso serviço. CONCLUSÕES: O presente estudo mostrou a importância da experiência da equipe e da concentração do tratamento de pacientes com câncer de esôfago em centros de referência, possibilitando melhorar significativamente o resultado pós-operatório.

ABSTRACT BACKGROUND: The incidence of esophageal cancer is high in some regions and the surgical treatment requires reference centers, with high volume, to make surgery feasible. AIMS: To evaluate patients undergoing minimally invasive esophagectomy by thoracoscopy in prone position for the treatment of esophageal cancer and to recognize the experience acquired over time in our service after the introduction of this technique. METHODS: From January 2012 to August 2021, all patients who underwent the minimally invasive esophagectomy for esophageal cancer were retrospectively analyzed. In order to assess the factors associated with the predefined outcomes as fistula, pneumonia, and intrahospital death, we performed univariate and multivariate logistic regression analyses, accounting for age as an important factor. RESULTS: Sixty-six patients were studied, with mean age of 59.5 years. The main histological type was squamous cell carcinoma (81.8%). The incidence of postoperative pneumonia and fistula was 38% and 33.3%, respectively. Eight patients died during this period. The patient's age, T and N stages, the year the procedure was performed, and postoperative pneumonia development were factors that influenced postoperative death. There was a 24% reduction in the chance of mortality each year, associated with the learning curve of our service. CONCLUSIONS: The present study presented the importance of the team's experience and the concentration of the treatment of patients with esophageal cancer in reference centers, allowing to significantly improve the postoperative outcomes.

O novo ensino médio permite ao estudante, num currículo de vários tópicos, que escolha a área de ciência e tecnologia, onde estão presentes habilidades sobre radiações/radioatividade. Trata-se de um tema que envolve diversas aplicações para a sociedade, como para a área médica, onde é possível diagnosticar e tratar doenças, bem como aplicações industriais e a produção de energia elétrica livre da emissão de gases estufa. No entanto, a forma como a radiação ionizante tem sido tratada pela mídia tende a afastar o jovem estudante do ensino médio dessa área da ciência. Devido à importância do tema, este trabalho traz uma proposta alternativa para o novo ensino médio, onde o ensino vai se dar de uma forma crítica, relativamente aprofundada e não tendenciosa. O material pode ser acessado online através do link https://sites.google.com/unicamp.br/radschool/.

The new high school allows the student, in a curriculum of various topics, to choose the area of science and technology, where skills on radiation/radioactivity are present. It is an issue that involves several applications for society, such as for the medical area, where it is possible to diagnose and treat diseases, as well as industrial applications and the production of electricity free from the emission of greenhouse gases. However, the way in which ionizing radiation has been treated by the media tends to drive young high school students away from this area of science. Due to the importance of the theme, this work presents an alternative proposal for the new high school, where teaching will take place in a critical, relatively in-depth and non-biased way.

Abstract Introduction: With aging there are changes in the senses and consequently, alterations in the function of taste and smell that influence the decompensation of chronic diseases. Objective: Know the sensory function and its association with dependence to perform basic and instrumental daily life activities in older adults with chronic diseases. Methodology: Correlational study in a sample comprised by 96 participants. The Instruments used were: Snellen Letter, Manual Hearing meter, Semmes-Weinstein monofilament, flavor test, Basic Tastes, and Barthel Index. The statistic analysis implied the use of descriptive and inferential statistics, Spearman Correlation, and Mann-Whitney U Test. Results: Seventy one percent (71%) had visual impairment; 48% got normal hearing in the left ear and 43% in the right ear; 24% rated with tactile alteration in the left foot and 30% with tactile alteration in the right foot; 77% presented alteration of smell and taste. Forty percent (40%) had dependence on Basic Activities (ABVD by its acronym in Spanish) and 24% in Instrumental Activities (AIVD by its acronym in Spanish). The relationship between touch in both feet and auditory acuity was identified with ABVD (p= <.05). Age and AIVD (p= <.001), sharp touch in the left foot (p = <.031), auditory (p= <.005), smell (p= <.018), and taste (p=<.047). The dependence on ABVD had no difference in the test with eyeglasses (U= 146,000; p-754) and without eyeglasses (U= 127,500; p-079); AIVD with eyeglasses (U= 115,000; p-079) and without eyeglasses (U= 160,000; p-202). Conclusions: The greater the function in the touch and hearing senses, the less the dependence to perform ABVDs and the greater the functions in the touch, hearing, and smell senses, the less the dependence on AIVDs.

Resumen Los cambios estructurales y el grado de madurez de tres carbones colombianos de las provincias de Santander y Antioquia se estudiaron utilizando un método de ajuste de curva simple y rápido de los parámetros RBS (la distancia entre la banda G y la banda D), FWHM-G (ancho total en la mitad del máximo de la banda G) y AR (área del espectro Raman), obtenido por deconvolución y resolución de banda de los espectros Micro-Raman. Los resultados fueron comparados mediante análisis morfológicos y químicos utilizando un microscopio electrónico de barrido SEM acoplado con un detector EDS de rayos X de estado sólido. Se obtuvo un porcentaje de reflectancia de vitrinita (%Ro) de 4.3 %, 3.8 % y 0.07 %, un porcentaje de carbono por análisis EDS de 91.47 %, 87.78 %, 73.4 %, una descripción morfológica por análisis SEM presentando superficies lisa, rugosa y rugosa-grumosa y tamaño de poro entre 0.7 µm - 0.8 µm, 1.3 µm - 1.5µm y 0.2 µm - 0.7 µm para las muestras de tipo antracita, semi-antracita y bituminoso, respectivamente. Los resultados mostraron que, con base en este método, fue posible obtener un modelo que permite analizar y caracterizar rápidamente el carbón. Los resultados se comparan muy bien con los de los carbones colombianos normalizados por otros métodos para mejorar la precisión de la medición. Sin embargo, el método modificado no ofreció un ajuste apropiado para el carbón de rango inferior y produjo valores de reflectancia extremadamente bajos. Este efecto posiblemente esté relacionado con la estructura molecular de la materia orgánica en el carbón o la presencia de interferencia de fluorescencia.

Abstract The structural changes and the degree of maturity of three Colombian coals from the Santander and Antioquia provinces were studied using a simple and fast curve fitting method of the RBS parameters (the distance between band G and band D), FWHM - G (total width at half the maximum of the G band) and AR (area of the Raman spectrum), obtained by deconvolution and band resolution of the Micro-Raman spectra. The results were compared by morphological and chemical analysis using a SEM scanning electron microscope coupled with a solid state X - ray EDS detector. A percentage of vitrinite reflectance (% Ro) of 4.3 %, 3.8 % and 0.07 % was obtained, a percentage of carbon by EDS analysis of 91.47 %, 87.78 %, 73.4 %, a morphological description by SEM analysis presenting smooth, rough surfaces and rough-lumpy and pore size between 0.7 µm - 0.8 µm, 1.3 µm - 1.5 µm and 0.2 µm - 0.7 µm for the anthracite, semi-anthracite and bituminous samples, respectively. The results showed that based on this method, it was possible to obtain a model that allows to rapidly analyze and characterize the coal. The results compare very well to those of Colombian coals normalized by other methods to improve the precision of the measurement. The modified method, however, did not offer an appropriate fit for the lower range coal and produced extremely low reflectance values. This effect is possibly related with the molecular structure of organic matter in coal or the presence of fluorescence interference.

Resumo As mudanças estruturais e o grau de maturidade de três carvões colombianos das províncias de Santander e Antioquia foram estudados usando um método de ajuste de curva simples e rápido dos parâmetros RBS (a distância entre a banda G e a banda D), FWHM- G (largura total na metade do máximo da banda G) e AR (área do espectro Raman), obtidos por deconvolução e resolução de banda dos espectros Micro-Raman. Os resultados foram comparados por análises morfológicas e químicas em um microscópio eletrônico de varredura em MEV acoplado a um detector de EDS de raios-X de estado sólido. Uma porcentagem de refletância de vitrinita (% Ro) de 4.3 %, 3.8 % e 0.07 % foi obtida, uma porcentagem de carbono por análise EDS de 91.47 %, 87.78 %, 73.4 %, uma descrição morfológica por análise MEV apresentando superfícies lisas e rugosas e rugosidade e tamanho de poro entre 0.7 µm – 0.8 µm, 1.3 µm – 1.5 µm e 0.2 µm – 0.7 µm para as amostras de antracita, semiantracita e betuminosa, respectivamente. Os resultados mostraram que, com base neste método, foi possível obter um modelo que permite analisar e caracterizar rapidamente o carvão. Os resultados se comparam muito bem aos de carvões colombianos normalizados por outros métodos para melhorar a precisão da medição. No entanto, o método modificado não forneceu um ajuste apropriado para o carbono de faixa inferior e produziu valores de refletância extremamente baixos. Este efeito está possivelmente relacionado à estrutura molecular da matéria orgânica do carvão ou à presença de interferência de fluorescência.

Abstract INTRODUCTION: Trypanosoma cruzi (Tc) infection is usually acquired in childhood in endemic areas, leading to Chagas disease, which progresses to Chagas cardiomyopathy in 20-30% of infected individuals over decades. The pathogenesis of Chagas cardiomyopathy involves the host inflammatory response to T. cruzi, in which upstream caspase-1 activation prompts the cascade of inflammatory chemokines/cytokines, cardiac remodeling, and myocardial dysfunction. The aim of the present study was to examine the association of two caspase-1 single nucleotide polymorphisms (SNPs) with cardiomyopathy. METHODS: We recruited infected (Tc+, n = 149) and uninfected (Tc−, n = 87) participants in a hospital in Santa Cruz, Bolivia. Cardiac status was classified (I, II, III, IV) based on Chagas cardiomyopathy-associated electrocardiogram findings and ejection fractions on echocardiogram. Genotypes were determined using Taqman probes via reverse transcription-polymerase chain reaction of peripheral blood DNA. Genotype frequencies were analyzed according to three inheritance patterns (dominant, recessive, additive) using logistic regression adjusted for age and sex. RESULTS: The AA allele for the caspase-1 SNP rs501192 was more frequent in Tc+ cardiomyopathy (classes II, III, IV) patients compared to those with a normal cardiac status (class I) [odds ratio (OR) = −2.18, p = 0.117]. This trend approached statistical significant considering only Tc+ patients in class I and II (OR = −2.64, p = 0.064). CONCLUSIONS: Caspase-1 polymorphisms may play a role in Chagas cardiomyopathy development and could serve as markers to identify individuals at higher risk for priority treatment.

Resumen El gobierno de los Estados Unidos, bajo la idea de la defensa de los intereses de sus connacionales en México, a través de notas diplomáticas desconoció una parte del contenido de la prescripción I del artículo 27 de la Constitución de 1927, dando paso a un diferendo diplomático entre ambos países. Con base en lo anterior, nuestro propósito es observar la postura del gobierno estadounidense respecto a la aplicación del reparto agrario por parte del presidente Lázaro Cárdenas, en el valle del Yaqui, Sonora, y las respuestas del gobierno mexicano. Es un estudio histórico de las relaciones entre México y los Estados Unidos, entendidas como interacciones entre organizaciones formales en su esfera gubernamental (gobiernos, diplomacia). La investigación revela que el gobierno cardenista aceptó la intromisión diplomática estadounidense y el pago de las compensaciones a sus connacionales, a pesar de que la razón jurídica estaba del lado de México e incluso, en la legislación mexicana en materia agraria, estaba contemplado el pago de indemnizaciones a los propietarios mexicanos, incluidos los nacionalizados.

Abstract A series of diplomatic notes issued by the U.S. government invoked the defense of their citizens’ interests in Mexico to disavow the contents of the Article 27, Section 1 in the Mexican Constitution of 1927, causing a diplomatic differendum between both countries. Our goal is to examine the posture of the American government regarding the agricultural land distribution program established by the Mexican President Lázaro Cárdenas at the Yaqui River Valley, Sonora, and the replies by the Mexican government. This historical assay about the US-Mexico relationships reveals that Cárdenas accepted the American diplomacy intromission and the compensations granted to American citizens despite the legal reason was on the Mexican side. Even in the agrarian legislation it was contemplated the payment of compensations to the Mexican landowners, including the nationalized ones.

ABSTRACT Abstract: Overactive bladder syndrome is one of the lower urinary tract dysfunctions with the highest number of scientific publications over the past two decades. This shows the growing interest in better understanding this syndrome, which gathers symptoms of urinary urgency and increased daytime and nighttime voiding frequency, with or without urinary incontinence and results in a negative impact on the quality of life of approximately one out of six individuals – including both genders and almost all age groups. The possibility of establishing the diagnosis just from clinical data made patients' access to specialized care easier. Physiotherapy resources have been incorporated into the urological daily practice. A number of more selective antimuscarinic drugs with consequent lower adverse event rates were released. Recently, a new class of oral drugs, beta-adrenergic agonists has become part of the armamentarium for Overactive Bladder. Botulinum toxin injections in the bladder and sacral neuromodulation are routine modalities of treatment for refractory cases. During the 1st Latin-American Consultation on Overactive Bladder, a comprehensive review of the literature related to the evolution of the concept, epidemiology, diagnosis, and management was conducted. This text corresponds to the first part of the review Overactive Bladder 18-years.

ABSTRACT Traditionally, the treatment of overactive bladder syndrome has been based on the use of oral medications with the purpose of reestablishing the detrusor stability. The recent better understanding of the urothelial physiology fostered conceptual changes, and the oral anticholinergics – pillars of the overactive bladder pharmacotherapy – started to be not only recognized for their properties of inhibiting the detrusor contractile activity, but also their action on the bladder afference, and therefore, on the reduction of the symptoms that constitute the syndrome. Beta-adrenergic agonists, which were recently added to the list of drugs for the treatment of overactive bladder, still wait for a definitive positioning – as either a second-line therapy or an adjuvant to oral anticholinergics. Conservative treatment failure, whether due to unsatisfactory results or the presence of adverse side effects, define it as refractory overactive bladder. In this context, the intravesical injection of botulinum toxin type A emerged as an effective option for the existing gap between the primary measures and more complex procedures such as bladder augmentation. Sacral neuromodulation, described three decades ago, had its indication reinforced in this overactive bladder era. Likewise, the electric stimulation of the tibial nerve is now a minimally invasive alternative to treat those with refractory overactive bladder. The results of the systematic literature review on the oral pharmacological treatment and the treatment of refractory overactive bladder gave rise to this second part of the review article Overactive Bladder – 18 years, prepared during the 1st Latin-American Consultation on Overactive Bladder.

Abstract: En | Text: En | PDF: En

INTRODUCTION: Stroke in young adults has seldom been studied in a necropsy series. The objective of the present clinical necropsy-based investigation was to analyze stroke and its relationship with cardiovascular and renal pathology in young adults. MATERIALS AND METHODS:The protocols of 52 clinical necropsies with diagnoses of stroke in patients aged 18 - 49 years, performed between the years 1990-2006, were reviewed. RESULTS: Hemorrhagic stroke was diagnosed in 36 patients (69.3%), whereas the remaining 16 (30.7%) had ischemic stroke. Hypertensive cardiopathy was evident in 88.4% of the cases. Chronic renal pathology, directly or indirectly related to hypertension, was observed in 55.7% of the patients. Ischemic stroke as a result of occlusive atherosclerotic disease was seen in 50% of cases. Cardiogenic emboli were found in 25% of the cadavers. Hemorrhagic stroke was associated with hypertension in 43% of the cases, with ruptured vascular malformations in 29%, and coagulopathies in 17% of the cases. Hypertensive cardiopathy was present in patients with either ischemic or hemorrhagic stroke (81.2% and 91.6%, respectively). The most frequently observed renal ailments were chronic pyelonephritis (23%) and nephrosclerosis (21.1%). These were associated with ischemic stroke in 43.7%, and 12.5% of the cases, respectively, and with 13.8% and 25% of the hemorrhagic stroke cases. DISCUSSION: Hypertensive cardiopathy, occlusive atherosclerotic disease, chronic pyelonephritis and nephrosclerosis are among the pathophysiologycal mechanisms that apparently and eventually interact to induce a significant number of cases of stroke in young adults. A chronic systemic inflammatory state appears to be an important related condition because it possibly constitutes an accelerant of the pathophysiologycal process.
