A Low-Cost Wearable Device to Estimate Body Temperature Based on Wrist Temperature.

The remote monitoring of vital signs and healthcare provision has become an urgent necessity due to the impact of the COVID-19 pandemic on the world. Blood oxygen level, heart rate, and body temperature data are crucial for managing the disease and ensuring timely medical care. This study proposes a low-cost wearable device employing non-contact sensors to monitor, process, and visualize critical variables, focusing on body temperature measurement as a key health indicator. The wearable device developed offers a non-invasive and continuous method to gather wrist and forehead temperature data. However, since there is a discrepancy between wrist and actual forehead temperature, this study incorporates statistical methods and machine learning to estimate the core forehead temperature from the wrist. This research collects 2130 samples from 30 volunteers, and both the statistical least squares method and machine learning via linear regression are applied to analyze these data. It is observed that all models achieve a significant fit, but the third-degree polynomial model stands out in both approaches. It achieves an R2 value of 0.9769 in the statistical analysis and 0.9791 in machine learning.

Conformação da 'moderna' enfermagem brasileira e interfaces com os Saberes Psi: um estudo historiográfico - 1932-1988 / Conformation of the 'modern' Brazilian nursing and interfaces with Psy Knowledge: a historiographical study - 1932-1988

RESUMO Neste estudo, objetivou-se descrever e analisar a circulação de Saberes Psi - Psicologia, Psicanálise e Psiquiatria - na 'Revista Brasileira de Enfermagem' entre 1932 e 1988. Metodologicamente, é uma pesquisa historiográfica cujas fontes primárias foram 59 textos da referida revista que abordaram o conhecimento mencionado. Os resultados indicaram que os Saberes Psi eram objetos de interesse daquele coletivo que passou a divulgá-los no periódico e a introduzi-los nos currículos das escolas de enfermagem. Foram apropriados para compor o processo de conformação da enfermeira moderna por, pelo menos, três mecanismos: 1) ensino de psicologia voltado para a formação moral e comportamental da enfermeira; 2) ensino de psicologia, para sua capacitação na assistência ao doente, além da saúde do corpo; e 3) ensino de psiquiatria, para capacitar a enfermeira no cuidado com o adoecimento mental. Notam-se, portanto, os Saberes Psi circulando no coletivo de pensamento dos autores que publicavam na revista e, concomitantemente, coadunando com o estilo de pensamento Nightingaleano de formação da enfermeira considerada ideal. Logo, tais Saberes aludiram à conformação daquilo que seria considerada a enfermagem 'moderna' brasileira.

ABSTRATCT This study aims to describe and analyze the circulation of Psy Knowledge - Psychology, Psychoanalysis, and Psychiatry - in the journal 'Revista Brasileira de Enfermagem', between 1932 and 1988. Methodologically, it is a historiographical research whose primary sources were 59 texts from the aforementioned journal that addressed such Knowledge. The results indicated that the Psy Knowledge were subjects of interest to that collective that started to publicize it, in the journal, and to introduce it in the curricula of the Nursing Schools. They were appropriated to compose the process of conformation of the modern nurse by, at least, three mechanisms, namely: 1) teaching of Psychology toward the moral and behavioral training of nurses; 2) teaching of Psychology for the training in patient care, in addition to health of the body; and 3) Psychiatry teaching to train nurses in caring for mental illness. Therefore, Psy Knowledge circulated in the thought collective of those authors who published in the journal and, concomitantly, in line with the Nightingale style of thought for the 'ideal' training of nurses. Hence, such Knowledge alluded to the conformation of what would be considered the 'modern' Brazilian nursing.

Towards implementing precision conservation practices in agricultural watersheds: A review of the use and prospects of spatial decision support systems and tools.

Agricultural nonpoint source (NPS) pollution leads to water quality degradation. While agriculture is faced with the challenge of feeding a growing population in a changing climate, farmers must also strive to minimize adverse impacts of agriculture on the environment. As a result, policies, and agri-environmental programs to promote agricultural conservation practices for controlling NPS pollution have been emerging. Despite progress, reducing NPS is a complex challenge that requires ongoing innovation and investment. A major challenge is to achieve an optimal spatial trade-off between the economic costs and positive environmental outcomes of conservation practices on complex agricultural landscapes. Geospatial systems and tools can help to address this challenge and enhance the effectiveness and efficiency of conservation efforts. However, using these tools for precision conservation is underexamined. This review paper aims to address this gap through a critical exploration of spatial decision support systems and tools to provide synthesized knowledge for implementing precision conservation practices. This paper proposes a conceptual framework to guide the implementation of precision conservation and identifies areas for further development of geospatial systems and tools on planning and assessment of precision conservation efforts. All of which will be helpful for decision-makers and watershed managers in determining the most effective approaches for precision conservation. Furthermore, this review highlights the need for further research and development towards establishing an integrated spatial decision support system framework, which can improve socio-economic, environmental, and ecological outcomes.

Situs inversus totalis: A challenge for cardiac resynchronization therapy.

Situs inversus totalis (SIT) is a congenital condition in which the major visceral organs are reversed or in a mirror image from their normal positions that affects one per 10,000 live births. It is associated with dextrocardia (DXC) in which the heart is located on the right side of the chest. We present a challenging cardiac resynchronization therapy (CRT) implantation in a 60-year-old man with SIT-DXC, heart failure, extreme bradycardia, wide QRS, and left ventricular (LV) dysfunction. The procedure was complex due to the mirror-image anatomy and the tortuous origin of the coronary sinus (CS) branches that required a subselection catheter for adequate lead implantation.

A Review of Cognitive Hybrid Radio Frequency/Visible Light Communication Systems for Wireless Sensor Networks.

The development and growth of Wireless Sensor Networks (WSNs) is significantly propelled by advances in Radio Frequency (RF) and Visible Light Communication (VLC) technologies. This paper endeavors to present a comprehensive review of the state-of-the-art in cognitive hybrid RF-VLC systems for WSNs, emphasizing the critical task of seamlessly integrating Cognitive Radio Sensor Networks (CRSNs) and VLC technologies. The central challenge addressed is the intricate landscape of this integration, characterized by notable trade-offs between performance and complexity, which escalate with the addition of more devices and increased data rates. This scenario necessitates the development of advanced cognitive radio strategies, potentially facilitated by Machine Learning (ML) and Deep Learning (DL) approaches, albeit introducing new complexities such as the necessity for pre-training with extensive datasets. The review scrutinizes the fundamental aspects of CRSNs and VLC, spotlighting key areas like Energy Efficient Resource Allocation, Industrial Scenarios, and Energy Harvesting, and explores the synergistic amalgamation of these technologies as a promising pathway for enhanced spectrum utilization and network performance. By delving into the integration of cognitive radio technology with visible light, this study furnishes valuable insights into the potential for innovative applications in wireless communication, presenting a balanced overview of the current advancements and prospective avenues in the field of cognitive hybrid RF/VLC systems.

Molecular variability of the Ancylostoma secreted Protein-2 (Aca-asp-2) gene from Ancylostoma caninum contributes to expand information on population genetic studies of hookworms.

Hookworm infection is a major public health problem in many regions of the world. Given the high levels of host morbidity and even mortality of the host caused by these infections, it is crucial to understand the genetic structure of hookworm populations. This understanding can provide insights into the ecology, transmission patterns, mechanisms of drug resistance, and the development of vaccines and immunotherapeutic strategies. Previously, we examined presumably neutral molecular markers, such as microsatellites and COI (Cytochrome C oxidase subunit 1) in Brazilian populations of Ancylostoma caninum. Here we analyze the molecular variability of a genomic fragment of the Aca-asp-2 (Ancylostoma secreted protein-2) gene from Ancylostoma caninum. This gene is a highly expressed and activated following the infection of the L3 larvae in the host. We obtained individuals of A. caninum from five different geographic locations in Brazil, sequenced and analyzed parts of the gene. The results revealed extensive polymorphism at this fragment, especially in the intronic region, indicating low selective pressure acting on these sequences. However, we also observed irregular distributions of nucleotides and polymorphisms in the coding region of this gene, resulting in the identification of 27 alleles. The data presented here contribute to expanding the understanding of population genetic studies of hookworms.

Candida palmioleophila: A New Emerging Threat in Brazil?

Human activity directly or indirectly causes climate change, promoting changes in the composition of the atmosphere. This change is beyond the variation of the natural climate. In this manner, climate change could create an environmental pressure which is enough to trigger new fungal diseases. In addition to climate alterations, the onset of the COVID-19 pandemic has also been associated with the emergence of fungal pathogens. Fungi showed that an inability to grow at high temperatures limits the capacity of fungi to infect mammals. However, fungi can develop thermotolerance, gradually adapting to rising temperatures due to climate change, and generating a greater number of disease-causing organisms. In the present study, we reported the detection and identification of Candida palmioleophila isolates recovered from raw sewage samples in Niteroi city, Rio de Janeiro State, Brazil, during a monitoring program for measuring SARS-CoV-2 presence and concentration. Using polyphasic taxonomy to identify the species and evaluating some virulence aspects of this species, such as biofilm formation and extracellular enzyme production, our data highlight this species as a possible emerging pathogen in Brazil, especially in the pandemic context.

Which one? A comparative study of traditional and sports uniforms on academic achievement, cognitive performance, playtime, bullying, and discrimination in adolescents: The Cogni-Action Project.

Objective: The aim of this study was to compare academic achievement, cognitive performance, playtime, bullying, and discrimination in adolescents according to traditional uniforms (TUs) and sports uniforms (SUs) worn at school, while simultaneously exploring the influence of the school vulnerability index. Methods: A total of 988 Chilean adolescents (52.6% boys) aged 10-14 years participated in this cross-sectional study. Academic achievement was evaluated by the average grade in maths, language, and science grades, while cognitive performance was assessed through eight cognitive tasks. TUs affecting physical activity, playtime, bullying, and discrimination were queried. Mixed model analyses were performed. Results: No differences were observed in academic achievement (TU: 5.4 ± 0.1 vs. SU: 5.5 ± 0.2, p = 0.785) or in cognitive performance (TU: 99.6 ± 0.8 vs. SU: 98.9 ± 1.8, p= 0.754) according to the school uniformtype. Moreover, 64.1 % of participants declared that wearing TU affects their physical activity (traditional uniforms: + 8 min and sports uniforms: + 20 min), and those who believed so spent more time playing than those who answered negatively (14.5 min, p = 0.012). Finally, adolescents wearing SU displayed a lower feeling of bullying and discrimination; this finding depended mainly on the school's vulnerability. Conclusion: It is concluded that wearing TU does not show an educational advantage at an academic and cognitive level that justifies its obligation. In addition, it could be suggested that schools consider adolescents' opinions in adopting a more comfortable uniform, such as the SU. This feasible and low-cost measure would help to increase adolescents' physical activity during the school day, and, contrary to belief, it would not be related to increased feelings of bullying and discrimination.

Suicide Attempt by Glass Shard Ingestion: A Case Report.

A 42-year-old man with schizophrenia and human immunodeficiency syndrome swallowed several glass shards in an attempted suicide. Two days later, he was admitted to the ER of the Florianópolis Hospital with a complaint of upper abdominal pain. The patient showed normal vital signs on physical examination; there was tenderness of palpation of the epigastrium. The investigation on admission included hemogram, CXR, abdominal X-ray, and upper GI scope. Radiographs showed several radiopaque image fragments in the stomach, as well as in the small and large intestines. Hemogram showed normal results. Upper gastrointestinal endoscopy found no signs of esophagogastroduodenal perforation; several glass shards were removed from the patient's stomach. The patient remained in the ward for four days and underwent continuous vital signs monitoring, serial physical examinations, hematimetric control, and daily imaging tests. He showed normal vital signs and progressive improvement of abdominal pain during hospitalization, although hematochezia episodes took place during defecation. The patient no longer complained of abdominal pain on the fifth hospitalization day; the complete removal of the glass fragments was confirmed through imaging examinations, and the patient was transferred to a specialized hospital in order to better treat his psychiatric condition.

Adoecimento Mental, Antipsiquiatria e Antidiagnóstico: Notas a Partir de Elso Arruda / Mental Illness, Anti-psychiatry, and Anti-diagnosis: Notes from Elso Arruda / Enfermedad Mental, Antipsiquiatría y Antidiagnóstico: Apuntamientos desde Elso Arruda

A conformação da Psicologia Clínica ocorreu por meio de tensionamentos produzidos por diferentes profissionais, envolvidos nas práxis da clínica psi, no país. Parte desses embates ressaltam a utilização de métodos e técnicas psicológicas, para solução de problemas de ajustamento, no campo Psi - Psiquiatria, Psicologia e Psicanálise. Esta pesquisa objetiva identificar e caracterizar tensionamentos no campo psi referentes à Psicologia Clínica a partir de publicações de um de seus personagens, Elso Arruda. Metodologicamente, essa é uma investigação sociobibliométrica, que se insere na interseção entre a História Social da Psicologia, a História da Psiquiatria e a História da Psicanálise. Para a análise do conteúdo das fontes primárias utilizamos o software Iramuteq. Os resultados sugerem que circularam, entre os saberes psi, discursos pró-reforma psiquiátrica, na década de 1960. As fontes indicam ainda uma mudança da noção de diagnóstico na clínica psi, norteada por uma proposta antipsiquiátrica e antidiagnóstica, bem como o uso da psicologia, da psicanálise e da fenomenologia existencial para compreender o indivíduo.

Clinical psychology's conformation occurred by tensions produced by different professionals involved into the praxis of Psy's clinic, in Brazil. Part of this struggle is related to psychological methods and techniques to solve adjustment problems in the Psy's field - Psychiatry, Psychology and Psychoanalysis. This research aims to identify and characterize those tensions related particularly to Clinical Psychology based on one of its characters, Elso Arruda. Methodologically, this is a socio-bibliometric investigation, which is inserted in the intersection between the Social History of Psychology, the History of Psychiatry and the History of Psychoanalysis. For the content analysis of the primary sources, we used the Iramuteq software. Our results suggest that, among the Psy knowledge in the 1960's, circulated proposals advocating psychiatric reform. Besides, these sources suggest a change in the notion of diagnosis guided by an antipsychiatric and antidiagnostic proposal, as well as the use of psychology, psychoanalysis, and existential phenomenology to understand the subject.

Sensitive fluorescent chemosensor for Hg(II) in aqueous solution using 4'-dimethylaminochalcone.

Mercury (Hg) is an element with high toxicity, especially to the nervous system, and fluorescent pigments are used to visualize dynamic processes in living cells. A little explored fluorescent core is chalcone. Herein, we synthesized chalcone (2E)-3-(4-(dimethylamino)phenyl)-1-phenylprop-2-en-1-one (8) and assessed its photophysical properties. Moreover, the application of this chemosensor in aqueous media shows a selective fluorescence quenching effect with Hg(II). The figures of merit for the chemosensor were calculated to be LOD = 136 nM and LOQ = 454 nM, as well as a stoichiometry of 1:1. Furthermore, the association constant (Ka) and fluorescence quenching constant (KSV) were calculated using the Benesi-Hildebrand and Stern-Volmer equations to be Ka= 9.08 × 104 and KSV= 1.60 × 105, respectively. Finally, by using a computational approach, we explain the interaction between chalcone (8) and Hg(II) and propose a potential quenching mechanism based on the blocking of photoinduced electron transfer.

Antiinflammatory activity of natural triterpenes-An overview from 2006 to 2021.

Terpenes are one of the most abundant classes of secondary metabolites produced by plants and can be divided based on the number of isoprene units (C5 ) in monoterpenes (2 units-C10 ), sesquiterpenes (3 units-C15 ), diterpenes (4 units-C20 ), triterpenes (6 units-C30 ), etc. Chemically, triterpenes are classified based on their structural skeleton including lanostanes, euphanes, cycloartanes, ursanes, oleananes, lupanes, tirucallanes, cucurbitanes, dammaranes, baccharanes, friedelanes, hopanes, serratanes etc. Additionally, glycosylated (saponins) or highly oxidated/degraded (limonoids) triterpenes could be found in nature. The antiinflammatory effect and action as immunomodulators of these secondary metabolites have been demonstrated in different studies. This review reports an overview of articles published in the last 15 years (from 2006 to 2021 using PubMed and SciFinder database) describing the antiinflammatory effects of different triterpenes with their presumed mechanism of action, suggesting that triterpenes could be appointed as natural products with future pharmaceutical applicability.

Historicizando a trajetória de um pioneiro: Reinier Johannes Antonius Rozestraten (1924-2008) / Historicizing a pioneer: Reinier Johannes Antonius Rozestraten (1924-2008)

As biografias têm ganhado espaço na História das Ciências, no geral e, em específico, na História da Psicologia. Elas têm permitido compreender a atuação de personagens relevantes na história da Psicologia, em diversos locais e, entre eles, no Brasil. Esteartigo se constitui como uma biografia de Reinier Johannes Antonius Rozestraten (1924-2008). A partir de fontes textuais (e.g., memoriais, relatórios, etc.) e orais (entrevista com ex-colegas e ex-alunos), apresentamos cidades pelas quais o biografado passou e parte de suas atividades vinculadas ao campo científico-profissional da Psicologia. As fontes foram analisadas a partir de seu conteúdo. Vemos um ator interessado em uma Psicologia científica, capaz de se envolver em questões aplicadas, do que a de uma personagem vinculada a uma teoria, em especial. Ademais, observamos uma atuação que concorreu à criação e desenvolvimento de Sociedades científico-profissionais. Assim, sua trajetória nos permite compreender os caminhos da Psicologia, no geral, e da Psicologia do Trânsito, em específico, no Brasil.

Biographies have calling attention in the History of Sciences, in general and, in particular, in the History of Psychology. They have allowed us to understand the role of relevant characters in the history Psychology, in different places and, among them, in Brazil. This article is a biography of Reinier Johannes Antonius Rozestraten (1924-2008). From textual (e.g., memorial, research reports, etc.) and oral sources (interview with colleagues and former students), we present cities through which he passed and part of his activities linked to the scientific-professional field of Psychology. Primary sources were analyzed from its contents. We note Rozestraten more interested in scientific psychology, capable of getting involved in applied issues, than that of acharacter linked to a theory, in particular. In addition, we observed an activity that contributed to the creation and development of various scientific-professional societies. Thus, its trajectory allows us to understand the paths of Psychology, in general, and of Traffic Psychology, in specific, in Brazil.

História e memória da profissão de psicólogo no Brasil: Legislações e contexto sócio-histórico(1940-1950) / History and memory of the profession of psychologist in Brazil: Legislation and sociohistorical context (1940-1950)

A formação do psicólogo, sua profissionalização e regulamentação da Psicologia são temáticas recorrentes de pesquisas e discussões, no Brasil. Nessa direção, objetivamos identificar e caracterizar condições do campo científico-profissional da Psicologia que estiveram envolvidas no processo da regulamentação da profissão entre as décadas de 1940 e 1950. Metodologicamente, esta é uma pesquisa na interlocução entre História Social da Psicologia e a História do Tempo Presente. As fontes primárias foram prioritariamente aqueles presentesno Dossiê Legislativo vinculado à proposição da Lei nº 4.119/62. Os resultados indicam a existência de condições típicas das comunidades científico-profissionais (e.g., sociedades, revistas, exercício profissional, etc.) antes da referida regulamentação. Tais condições respondiam ao projeto de “modernização” nacional a partir de aplicações e da formação de “especialistas” em Psicologia. Assim, o que nos parece é que, para que profissão e a formação fossem legisladas, parte das condições necessárias para sua existência já estavam presentes no país.

The training of psychologists, their professionalization and regulation of Psychology are recurrent themes of research and debates in Brazil. Therefore, we aim to identify and characterize conditions in the scientific-professional field of Psychology involved in the process of regulation of the profession between the 1940s and 1950s. Methodologically, this research operates in between Social History of Psychology and History of the Present Time. The primary sources were first and foremost those present inthe Law No. 4,119/62’s legislative process. The results indicate the existence of typical conditions of scientific-professional communities (e.g., societies, journals, professional practice, etc.) before the aforementioned regulation. Such conditions werealigned to the national “modernization” project with its applicationsand the training of “specialists” in Psychology. Thus, one would see that, for the profession and training to be legislated, part of the necessary conditions for its existence were already present in the country.
