APPLICATION OF MASS SPECTROMETRY WITH PAPER SPRAY IONIZATION AND THE OPLS-DA CHEMOMETRIC METHOD FOR THE DIAGNOSIS OF PROSTATE CANCER BY ANALYSIS OF URINE SAMPLES. In this study, paper spray ionization mass spectrometry (PSI-MS) allied to orthogonal projections on the latent structure-discrimination analysis (OPLS-DA) was employed to differentiate urine samples from patients with prostate cancer and control individuals (without prostate cancer). The parameters of sensitivity, specificity, efficiency and Matthew’s correlation coefficient determined to analyze the efficiency and quality of the OPLS-DA model obtained a value equal to 1, which means, respectively, that the model has a good performance to correctly classify true positive samples and true negatives. These results showed 100% correct classification of the samples from the training and test set, demonstrating a high efficiency of the OPLS-DA model when classifying all samples considered as belonging to the class of interest (urine from control patient) into class 1 and all samples considered as belonging to the non-interest class (urine from patients with prostate cancer) in class 0. This efficiency resulting from the application of this model suggests that the PSI-MS combined to OPLS-DA is a promisor approach for a rapid diagnosis of prostate cancer, via chemical fingerprints of urine samples.

Este volume surge como consequência direta do Simpósio internacional PAPER TRAILS: post-industrial histories, technical memories and art practices in Tomar que teve lugar em Tomar (Portugal) entre 25 e 27 de maio de 2022. Por sua vez, o simpósio insere-se num projeto homónimo concebido, em parceria com colaboradoras da École de Design et Haute École d’Art du Valais (EDHEA), no Centro de Tecnologia, Restauro e Valorização das Artes (TECHN&ART), uma unidade de Investigação e Desenvolvimento financiada pela Fundação para a Ciência e a Tecnologia (FCT) com a referência UID/05488/2020 e pertencente ao Instituto Politécnico de Tomar (IPT).

Se trata de exploraciones esenciales en torno al papel, su textura y las relaciones originadas a partir de su recorte y superposición en capas. Son obras minimalistas en su técnica que despliegan paisajes de formas plegadas y laminadas con profundidad y equilibrio que parten también del imaginario personal sobre la arquitectura. Las composiciones tienen un formato de 21x21 cm. Las mismas reglas operan en todas ellas: el orden y el número de capas, colores, etc., pero se recombinan en cada pieza de forma diferente. Las capas de papel se separan entre sí a unas distancias concretas y se unen de forma solidaria sólo por una pestaña en la parte superior, lo que permite una cierta libertad y tolerancia en la separación entre ellas, de forma que la percepción puede variar levemente en función del plegado o la curvatura del papel, incluso de las condiciones de humedad y atmosféricas.

Global warming is a result of the increased emission of greenhouse gases. The consequences of this climate change threaten society, biodiversity, food and resource availability. The consequences include an increased risk of cardiovascular (CV) disease and cardiovascular mortality.In this position paper, we summarize the data from the main studies that assess the risks of a temperature increase or heat waves in CV events (CV mortality, myocardial infarction, heart failure, stroke, and CV hospitalizations), as well as the data concerning air pollution as an enhancer of temperature-related CV risks. The data currently support global warming/heat waves (extreme temperatures) as cardiovascular threats. Achieving neutrality in emissions to prevent global warming is essential and it is likely to have an effect in the global health, including the cardiovascular health. Simultaneously, urgent steps are required to adapt the society and individuals to this new climatic context that is potentially harmful for cardiovascular health. Multidisciplinary teams should plan and intervene healthcare related to temperature changes and heat waves and advocate for a change in environmental health policy. Resumo: O aquecimento global é uma das consequências do aumento da emissão de gases com efeito de estufa. Essa consequência das alterações climáticas é uma ameaça à sociedade, à biodiversidade e à disponibilidade de recursos e alimentos. As consequências para a saúde do aquecimento global incluem o aumento do risco de doenças cardiovasculares (CV) e da mortalidade cardiovascular.Neste position paper resumimos os dados dos principais estudos que avaliam o risco do aumento de temperatura ou a exposição a ondas de calor nos eventos CV (mortalidade CV, enfarte do miocárdio, insuficiência cardíaca, acidente vascular cerebral e hospitalizações CV), assim como os dados relativos à poluição do ar como um potenciador dos riscos de eventos CV relacionados com o aumento da temperatura. Os dados atualmente disponíveis confirmam que o aquecimento global e as ondas de calor (temperaturas extremas) são ameaças cardiovasculares. Nesse contexto, a neutralidade nas emissões deve ser um objectivo prioritário, de modo a reduzir o aquecimento global e, desse modo, reduzir o seu impacto na saúde global, inclusive a saúde cardiovascular. Simultaneamente, deverão ser empregues medidas urgentes de adaptação setorial ao novo contexto climático, potencialmente mais nefasto para a saúde cardiovascular. Equipes multidisciplinares devem planear e intervir nos cuidados de saúde relacionados com o calor e discutir as políticas de saúde relacionadas com o ambiente.

The field of Cardio-Oncology has grown significantly, especially during the last decade. While awareness of cardiotoxicity due to cancer disease and/or therapies has greatly increased, much of the attention has focused on myocardial systolic disfunction and heart failure. However, coronary and structural heart disease are also a common issue in cancer patients and encompass the full spectrum of cardiotoxicity. While invasive percutaneous or surgical intervention, either is often needed or considered in cancer patients, limited evidence or guidelines are available for dealing with coronary or structural heart disease. The Society for Cardiovascular Angiography and Interventions consensus document published in 2016 is the most comprehensive document regarding this particular issue, but relevant evidence has emerged since, which render some of its considerations outdated. In addition to that, the recent 2022 ESC Guidelines on Cardio-Oncology only briefly discuss this topic.As a result, the Portuguese Association of Cardiovascular Intervention and the Cardio-Oncology Study Group of the Portuguese Society of Cardiology have partnered to produce a position paper to address the issue of cardiac intervention in cancer patients, focusing on percutaneous techniques. A brief review of available evidence is provided, followed by practical considerations. These are based both on the literature as well as accumulated experience with these types of patients, as the authors are either interventional cardiologists, cardiologists with experience in the field of Cardio-Oncology, or both. Resumo: A Cardio-Oncologia cresceu consideravelmente, particularmente ao longo da última década. Não obstante o aumento de sensibilização relativamente à cardiotoxicidade secundária ao cancro e/ou a terapêuticas oncológicas, muita da atenção tem-se focado na disfunção sistólica e insuficiência cardíaca. Todavia, a doença coronária e estrutural cardíaca representam também um desafio comum em doentes oncológicos, fazendo assim parte do abrangente conceito de Cardio-Oncologia. Apesar da necessidade de intervenção invasiva, percutânea ou cirúrgica ser frequentemente necessária ou considerada em doentes com cancro, é escassa a evidência ou recomendações relativas à doença coronária ou estrutural neste subgrupo. O documento de consenso da Society for Cardiovascular Angiography and Interventions, publicado em 2016, é a referência mais completa relativamente a esta problemática. Contudo, alguma evidência que entretanto surgiu torna necessária uma atualização. Adicionalmente, as recentes recomendações de 2022 em Cardio-Oncologia da Sociedade Europeia de Cardiologia abordam este assunto somente de forma muito sucinta.Por este motivo, a Associação Portuguesa de Intervenção Cardiovascular e o Grupo de Estudos de Cardio-Oncologia associaram-se para produzir um Artigo de Posição sobre Intervenção Cardíaca em doentes com cancro, com foco nas técnicas percutâneas. Procedeu-se a uma breve revisão da literatura, seguida de considerações práticas. Estas baseiam-se na evidência disponível, bem como na experiência acumulada dos autores, que são Cardiologistas de Intervenção, Cardiologistas dedicados à área da Cardio-Oncologia, ou ambos.

During the recycling of a cardboard box in the shape of a right prism with a square base to build a tetrahedron, there was the curious coincidence that the height of the first was equal to the inclined height of the second. After some bending and cutting on the prism, its dynamic conversion to the tetrahedron and vice versa was achieved. This fact motivated us to carry out a study on the meaningful learning of a small group of participants (N = 10) with minimum primary school education, regarding the volume of these two common geometric bodies. It was found that 70 % of the study population thought that the volumes were equal and that 100 % had forgotten the formula to calculate the volume of the tetrahedron. A template to build the model and a video to illustrate the mentioned transformation process are also presented.

As in other countries, In Brazil, new genetic materials of Eucalyptus spp. and their hybrids are multiplied through cloning. These materials, currently in experimental trials, must undergo several stages to select the best ones for pulp and paper production. Therefore, new studies on wood quality are essential. Therefore, this study aimed to group 11 clones of Eucalyptus spp. wood, from a clonal plantation in the municipality of Palmital, São Paulo State, for the production of paper and cellulose. For this purpose, four trees of each clone of 4-year-old Eucalyptus spp. were collected. From each tree, a log of 1 m in length was taken from the base of the tree, for the study of the characterization of the basic density and cellular dimensions of the wood. The results showed that there were significant differences between clones for basic density, fiber length, vessel element length and fiber wall thickness. The Runkel ratio, wall fraction and stiffness coefficient did not show significant differences between the different genotypes. From the results obtained, we can conclude that clones can be differentiated only by basic density, fiber length, vessel element length and fiber wall thickness. The Runkel index, flexibility coefficient and wall fraction of Eucalyptus spp. were more efficient to group the clones into two groups.

Occupational toxicology in the paper industry aims to study the occupational risks of exposure to chemical, physical and biological compounds used in the workplace, in addition to helping and preventing the possible appearance of adverse effects on the health of workers due to exposure to themselves. The pulp and paper industries use several chemical agents in the production of packaging, demanding attention to handling due to their toxic action, currently research in this area is scarce. In turn, this article sought to demonstrate, through questionnaires and chemical analysis, contamination by hydrochloric acid and sodium hydroxide in workers during their work activity in a paper industry located in southern Brazil. Seeking to increase the studies, the workers' knowledge about the agents was investigated, as well as the use of Personal Protective Equipment (PPE) and the contamination of these individuals with the aforementioned agents. To achieve these objectives, interviews were applied to employees from four different shifts and the clothes were analyzed after the end of the shift through titration and pHmetry analysis. The results of the analyzes showed a lack of awareness among the workers, evidence of contamination and traces of sodium hydroxide on the employees' clothing. These results imply reflection on the indispensability of personal protective equipment. Highlighting the need for the routine use of PPE, as well as offering the necessary qualification for workers, in order to prevent and minimize occupational accidents. [ABSTRACT FROM AUTHOR]

In recent years, technological development in analytical instrumentation has progressed vigorously, which has allowed the evolution of analytical techniques that play an indispensable role within society, highlighting mass spectrometry. Parallel to the technological advance of this technique, the development of new ionization methods that are simpler, faster, and allow direct analysis without the need for prior treatment or sample processing is underway. The methods of ambient ionization derived from paper spray have been developing rapidly in current days, mainly in the forensic field, due to the chemical modifications made in the paper substrate and the introduction of new types of organic materials that function as a probe/substrate to collect, store, and ionize the sample, then enabling more efficient and selective analyzes. This review highlights direct analyzes by applying paper spray ionization in the forensic field and some variations of this technique, including Thread Spray Ionization (TSI) when a fabric thread is used; Touch Spray Ionization (TSI), which uses materials such as metallic needles, medical swabs, and wooden sticks; Fiber Spray Ionization (FSI), which applies polymeric fibers as substrates.

ABSTRACT BACKGROUND: The concept introduced by protocols of enhanced recovery after surgery modifies perioperative traditional care in digestive surgery. The integration of these modern recommendations components during the perioperative period is of great importance to ensure fewer postoperative complications, reduced length of hospital stay, and decreased surgical costs. AIMS: To emphasize the most important points of a multimodal perioperative care protocol. METHODS: Careful analysis of each recommendation of both ERAS and ACERTO protocols, justifying their inclusion in the multimodal care recommended for digestive surgery patients. RESULTS: Enhanced recovery programs (ERPs) such as ERAS and ACERTO protocols are a cornerstone in modern perioperative care. Nutritional therapy is fundamental in digestive surgery, and thus, both preoperative and postoperative nutrition care are key to ensuring fewer postoperative complications and reducing the length of hospital stay. The concept of prehabilitation is another key element in ERPs. The handling of crystalloid fluids in a perfect balance is vital. Fluid overload can delay the recovery of patients and increase postoperative complications. Abbreviation of preoperative fasting for two hours before anesthesia is now accepted by various guidelines of both surgical and anesthesiology societies. Combined with early postoperative refeeding, these prescriptions are not only safe but can also enhance the recovery of patients undergoing digestive procedures. CONCLUSIONS: This position paper from the Brazilian College of Digestive Surgery strongly emphasizes that the implementation of ERPs in digestive surgery represents a paradigm shift in perioperative care, transcending traditional practices and embracing an intelligent approach to patient well-being.

Abstract Objective The purpose of the present study is to standardize and evaluate the use of the immunoglobulin G (IgG) antibody avidity test on blood samples from newborns collected on filter paper to perform the heel test aiming at its implementation in ongoing programs. Methods Blood samples from newborns were collected on filter paper simultaneously with the heel prick test. All samples were subjected to immunoglobulin M IgM and IgG enzyme-linked immunosorbent assays (ELISA). Peripheral blood was collected again in the traditional way and on filter paper from newborns with high IgG levels (33). Three types of techniques were performed, the standard for measuring IgG in serum, adapted for filter paper and the technique of IgG avidity in serum and on filter paper. The results of the avidity test were classified according to the Rahbari protocol. Results Among the 177 samples, 17 were collected in duplicate from the same child, 1 of peripheral blood and 1 on filter paper. In this analysis, 1 (5.88%) of the 17 samples collected in duplicate also exhibited low IgG avidity, suggesting congenital infection. In addition, the results obtained from serum and filter paper were in agreement, that is, 16 (94.12%) samples presented high avidity, with 100% agreement between the results obtained from serum and from filter paper. Conclusion The results of the present study indicate that the avidity test may be another valuable method for the diagnosis of congenital toxoplasmosis in newborns.

Este artigo tem por objetivo identificar os fatores que têm afetado as receitas das exportações de celulose e papel e papelão, no período de 2001 a 2020. Especificamente pretende-se quantificar as variações nas receitas provenientes da taxa de câmbio, do preço internacional e da quantidade exportada de celulose e de papel e papelão e identificar os principais eventos associados essas variações. Para tanto, utilizou-se o método diferencial-estrutural, conhecido como shift-share, que decompõe as variações da receita de exportação em efeitos parciais proporcionado por outras variáveis relacionadas. Os resultados mostram que mesmo quando os efeitos do preço internacional e a taxa de câmbio são desfavoráveis a quantidade exportada de celulose e de papel e papelão tem sido crescente, e proporcionando efeito total positivo nas receitas das exportações. Somente em quatro grandes momentos houve queda nas receitas das exportações destes produtos, momentos estes que coincidem com a ocorrência das seguintes crises: atentado a torres gêmeas (2002), crise do subprime (2008), crise política interna (2016) e pandemia (Covid-2019). ABSTRACT: This paper aims to identify the factors that have affected revenues from pulp and paper and paperboard exports, in the period from 2001 to 2020. Specifically, it intends to quantify the variations in revenues arising from the exchange rate, the international price and the exported quantity of Wood pulp and paperbord and identify the main events associate these variations. For this purpose, the differential-structural method, known as shift-share, was used, which breaks down changes in export revenue into partial effects provided by other related variables. The results show that even when the effects of the international price and the exchange rate are unfavorable, the exported quantity of woodpulp and paperboard has been increasing, providing a positive overall effect on export revenues. Only in four major moments were there decreases in revenues from exports of these products, moments that coincide with the occurrence of the following crises: attack on the twin towers (2002), subprime crisis (2008), internal political crisis (2016) and pandemic (Covid- 2019).
