Treatment And Follow-Up Guidelines For Multiple Brain Metastases: A Systematic Review
Brain metastases are a complication of primary cancer, representing the most
common type of brain tumor in adults. The management of multiple brain
metastases represents a clinical challenge worldwide in finding the optimal
treatment for patients considering various individual aspects. Managing
multiple metastases with stereotactic radiosurgery (SRS) is being increasingly
used because of quality of life and neurocognitive preservation, which do not
present such good outcomes when dealt with whole brain radiation therapy
(WBRT). After treatment, analyzing the progression of the disease still
represents a clinical issue, since it is difficult to determine a standard
schedule for image acquisition. A solution could be the applying artificial
intelligence, namely predictive models to forecast the incidence of new
metastases in post-treatment images. Although there aren't many works on this
subject, this could potentially bennefit medical professionals in early
decision of the best treatment approache
Multilingual Natural Language Processing Model for Radiology Reports -- The Summary is all you need!
The impression section of a radiology report summarizes important radiology
findings and plays a critical role in communicating these findings to
physicians. However, the preparation of these summaries is time-consuming and
error-prone for radiologists. Recently, numerous models for radiology report
summarization have been developed. Nevertheless, there is currently no model
that can summarize these reports in multiple languages. Such a model could
greatly improve future research and the development of Deep Learning models
that incorporate data from patients with different ethnic backgrounds. In this
study, the generation of radiology impressions in different languages was
automated by fine-tuning a model, publicly available, based on a multilingual
text-to-text Transformer to summarize findings available in English,
Portuguese, and German radiology reports. In a blind test, two board-certified
radiologists indicated that for at least 70% of the system-generated summaries,
the quality matched or exceeded the corresponding human-written summaries,
suggesting substantial clinical reliability. Furthermore, this study showed
that the multilingual model outperformed other models that specialized in
summarizing radiology reports in only one language, as well as models that were
not specifically designed for summarizing radiology reports, such as ChatGPT.Comment: Problems with the mode

LOCUS (LOng Covid-Understanding Symptoms, events and use of services in Portugal): A three-component study protocol
Study ProtocolApproximately 10% of patients experience symptoms of Post COVID-19 Condition (PCC) after a SARS-CoV-2 infection. Akin acute COVID-19, PCC may impact a multitude of organs and systems, such as the cardiovascular, respiratory, musculoskeletal, and neurological systems. The frequency and associated risk factors of PCC are still unclear among both community and hospital settings in individuals with a history of COVID-19. The LOCUS study was designed to clarify the PCC’s burden and associated risk factors. LOCUS is a multi-component study that encompasses three complementary building blocks. The “Cardiovascular and respiratory events following COVID-19” component is set to estimate the incidence of cardiovascular and respiratory events after COVID-19 in eight Portuguese hospitals via electronic health records consultation. The “Physical and mental symptoms following COVID-19” component aims to address the community prevalence of self-reported PCC symptoms through a questionnaire-based approach. Finally, the "Treating and living with Post COVID-19 Condition" component will employ semi-structured interviews and focus groups to characterise reported experiences of using or working in healthcare and community services for the treatment of PCC symptoms. This multi-component study represents an innovative approach to exploring the health consequences of PCC. Its results are expected to provide a key contribution to the optimisation of healthcare services design.This study is sponsored by Pfizer (grant code #68639655).info:eu-repo/semantics/publishedVersio
COMPARATIVE EVALUATION OF SKIN SUTURE IN RATS WITH POLYGLYCAPRONE 25 AND NYLON
ABSTRACT Currently, the market offers a wide variety of suture threads, made of materials with different structural and chemical properties. Among many other characteristics, they vary in origin, absorption or degradation, and structure. From this variety, the clinical doubt arises as to which material provides the patient with the best healing quality. Objective: This study aims to comparatively evaluate two different types of suture threads-Monocryl® (polyglycaprone 25) and Ethilon® (nylon)-regarding their ability to aid in tissue regeneration by a histological and immunohistochemical analysis of the skin of rats sutured with the aforementioned materials. Methods: This basic experimental study used 12 adult Wistar rats, randomly divided into three groups with four animals each and subjected to four longitudinal incisions under anesthesia. Each group corresponded to a postsurgical evaluation date (one, seven, and 14 days). Results: At 14 postoperative days, the studied groups had no histological difference. However, the use of nylon thread showed greater evidence of earlier fibrotic union. Conclusion: This study found no histological difference in healing 14 days after surgery among the techniques and the types of suture threads. Level of Evidence II, Therapeutic Studies
Wellbore integrity in a saline aquifer : experimental steel-cement interface degradation under supercritical CO2 conditions representative of Brazil’s Parana basin
From our work, significant progress has been made in understanding the degradation of cement-casing systems. The CO2 degradation process was evaluated in specimens with a large interfacial defect, such as large annular spaces, voids and/or channels, which may be the result of a poor cementing job. From the experiments showing no interfacial defect, no signs of degradation were observed, while from experiments showing interfacial defect, both the cement and steel undergo significant degradation. In the well casing, the CO2-rich brine affects the steel phase, leaching Fe2+ ions into solution and promoting FeCO3 precipitation on the material surface, while on the cement sheath, two processes are occurring: (i) the portlandite dissolution and (ii) the cement carbonation process. Then, iron (Fe2+) starts to migrate into the cement structure, compromising the material’s self-healing and pore-blocking features, while calcium (Ca2+) starts to compose the corrosion film from the formation of mixed carbonates (FexCayCO3) so reducing the corrosion layer’s protection. Finally, both ions (Ca2+ and Fe2+) become so abundant in the material vicinity that they may form calcium carbonate (CaCO3) on the corrosion layer and iron carbonate (FeCO3) in the cement matrix. Thus, from our results, the degradation mechanisms of the cement-casing system in CO2-rich brine was revised
DILEMAS DA EPISTEMOLOGIA AMBIENTAL
The perception crisis as part of the scientific knowledge crisis is expanded by inversions caused by merchandise development. They are interdependent dimensions of the environmental epistemology dilemmas which have been analyzed in this study, such as the customization of goods and the reification of people. These and other inversions obstruct the understanding of essential aspects relating to the current environmental issues, arising from a particular development model driven by production and consumption. Environmental epistemology is part of a science driven by the permanent conflict due to the inversion that maintains the inverted reality since the development of merchandise. Such science constitutes itself through interdisciplinary exercise, having in knowledge dialogue its own dynamism.A crise de percepção como parte da crise do conhecimento científico é expandida pelas inversões provocadas pelo desenvolvimento da mercadoria. São dimensões interdependentes dos dilemas da epistemologia ambiental analisadas por este texto, tais como a personalização das mercadorias e a coisificação das pessoas. Essas e outras inversões obstaculizam a compreensão de aspectos imprescindíveis, referentes à questão ambiental atual, advindos de um determinado modelo de desenvolvimento impulsionado pela produção e pelo consumo. A epistemologia ambiental é parte de uma ciência impulsionada pela conflituosidade permanente devido à inversão que mantém a realidade invertida desde o desenvolvimento da mercadoria. Tal ciência se constitui por intermédio do exercício interdisciplinar tendo no diálogo dos saberes o seu dinamismo

Practical Science and Environmental Education Workshop in Manaus, Brazil
It is an unequivocal fact that Amazonian tropical forest is the largest remaining primary forest in the world. The ecosystem in the region is e tremely comple with high biodiversity (Peres et al. 2010). Conservation and protection of the dynamic forest and river regions is e tremely important not only for the natural environments, but also for the economy and social dependence of benefits from such abundant natural environments. Important natural parameters that affect status of the natural environments include light (natural sunlight), soil, and water, which abundantly e ist in the Amazon region. Solar energy is the primary energy source for the majority of living organisms in both terrestrial and aquatic ecosystems, and drives the diurnal and seasonal cycles of biogeochemical processes (Monteith & Unsworth 2013). In particular, in situ light data remains one of the most underappreciated data measurements although having a significant impact on the physical, chemical and biological processes in the ecosystem (Johnsen 2012). Soil provides the fundamental basis for all terrestrial living organisms including the Amazonian forests as well as life-sustaining infrastructure for human society. Water is the most essential single entity to constitute all organisms from a single cell to the earth. Understanding of importance and roles of each factor and interaction of such comple dynamics in the natural environments can serve as fundamental platform for natural scientists, particularly for young scientists such as university students. The objective of this workshop was to provide hand- on scientific and environmental education for university students in Manaus, Amazonas, Brazil through practical field measurements using the three most important parameters in the natural ecosystem composed of natural sunlight, soil, and water. The workshop was divided into a series of lectures, in situ field sampling, and data processing, analysis and interpretation with the ultimate goal of empowering the undergraduate students with research-centered environmental education and e perience of developing international collaboration.departmental bulletin pape
