RESUMO

Self-Sovereign Identity (SSI) is an identity model centered on the user. The user maintains and controls their data in this model. When a service provider requests data from the user, the user sends it directly to the service provider, bypassing third-party intermediaries. Thus, SSI reduces identity providers' involvement in the identification, authentication, and authorization, thereby increasing user privacy. Additionally, users can share portions of their personal information with service providers, significantly improving user privacy. This identity model has drawn the attention of researchers and organizations worldwide, resulting in an increase in both scientific and non-scientific literature on the subject. This study conducts a comprehensive and rigorous systematic review of the literature and a systematic mapping of theoretical and practical advances in SSI. We identified and analyzed evidence from reviewed materials to address four research questions, resulting in a novel SSI taxonomy used to categorize and review publications. Additionally, open challenges are discussed along with recommendations for future work.

RESUMO

Antecedentes y objetivo: El tratamiento del colesteatoma es quirúrgico en la mayoría de los casos. Cuando está indicado, es preferible optar por una técnica quirúrgica reconstructiva con el doble propósito de eliminar la enfermedad y preservar o mejorar la audición del paciente. En 2017 se publicó una nueva clasificación del colesteatoma por parte de la European Academy of Otology and Neuro-Otology/Japanese Otological Society (EAONO/JOS). El objetivo de este estudio es determinar la influencia que tanto la técnica quirúrgica empleada como la clasificación de la enfermedad tienen en los resultados auditivos de los pacientes. Materiales y métodos: Se realiza un estudio retrospectivo que incluye pacientes intervenidos de colesteatoma mediante una técnica reconstructiva entre 2012 y 2017. A partir de la tomografía computarizada (TC) prequirúrgica de cada paciente se estadifica la enfermedad según la clasificación de la EAONO/JOS. Los datos audiológicos obtenidos mediante audiometría tonal liminar (ATL) pre y postoperatoria son analizados en función de la técnica quirúrgica empleada y según el estadio de la enfermedad. Resultados: Se incluyen 143 pacientes con umbrales auditivos sin diferencias significativas antes de la cirugía. Al año de la intervención, el umbral medio auditivo (pure tone average [PTA]) aéreo y el umbral diferencial auditivo (UDA) medio mejoran significativamente (p=0,01 y p=0,001) en toda la muestra. Los pacientes intervenidos con técnica cerrada en dos tiempos presentan mejores resultados en el PTA aéreo postoperatorio y UDA medio posquirúrgico que los operados mediante técnica abierta (p=0,007 y p=0,014). El PTA aéreo postoperatorio y el UDA medio postoperatorio mejoran en los pacientes intervenidos con técnica cerrada en dos tiempos quirúrgicos (p=0,001 y p=0,013), en comparación con la audición previa que presentaban. El UDA medio postoperatorio también mejora significativamente en los pacientes operados mediante técnica abierta (p=0,008). Conclusiones: Todas las técnicas quirúrgicas reconstructivas producen una mejora significativa de la audición al año de la intervención. En nuestro estudio esta mejora es significativamente superior con una timpanoplastia con mastoidectomía cerrada en dos tiempos quirúrgicos.(AU)


Introduction and objective: The treatment of cholesteatoma is surgical in most cases. When it is indicated, it is preferable to choose a reconstructive surgical technique with the dual purpose of eradicating the disease and preserving or improving the patient's hearing. In 2017, the European Academy of Otology and Neuro-Otology/Japanese Otological Society (EAONO/JOS) published a new cholesteatoma classification. The aims of this study are to determine the influence of the surgical technique use and this classification on patient's hearing outcomes. Methods: A retrospective study that include patients who underwent reconstructive surgery of cholesteatoma between 2012 and 2017 is carried out. Based on pre-surgical computed tomography (CT) images, disease is staged according to the EAONO/JOS classification. Hearing outcomes obtained by pre and postoperative pure tone audiometry are analysed according to the surgical technique used and according to the stage of the disease. Results: 143 patients with no statistically significant differences in hearing thresholds before surgery are included. One year after surgery, all the patients’ airbone pure tone average (PTA) and mean differential auditory threshold have improved significantly (P = .01 and P = .001). Those patients who undergo tympanoplasty with two-stage canal wall up mastoidectomy presente better postsurgical air PTA and postsurgical mean differential auditory threshold outcomes (P=.007 and P=.014) than those patients who underwent tympanoplasty with canal wall down mastoidectomy. Moreover, the patients who underwent tympanoplasty with two-stage canal wall up mastoidectomy had improved airbone PTA and mean differential auditory threshold one year after the surgery with statistical significance (P=.001 and P=.013). The mean differential auditory threshold is also better (P=.008) in the patients who undergo tympanoplasty with canal wall down mastoidectomy one year after the procedure. Conclusions: Reconstructive surgical techniques improve hearing one year after surgery. In our study, this improvement is significantly greater with tympanoplasty with two-stage canal wall up mastoidectomy.(AU)

RESUMO

Los productos sanitarios abarcan un amplio rango de artículos imprescindibles en la asistencia sanitaria y cuidados de salud. En 2017 se aprobó un nuevo reglamento que los regula en la Unión Europea, y cuya entrada en vigor fue en 2021. En él se especifican su definición legal, su clasificación, sus procedimientos de evaluación de la conformidad, los requerimientos de las investigaciones clínicas que evalúan su seguridad y/o funcionamiento y su base de datos europea. Pese a los intentos por sistematizar la definición legal de producto sanitario en el nuevo reglamento, la determinación de la situación reglamentaria de los artículos conocidos como ‘productos frontera’, para los que diferentes normativas podrían ser de aplicación (como en la frontera con los complementos alimenticios, los cosméticos, los productos de cuidado personal, los biocidas, los equipos de protección individual y los productos de consumo), no está exenta de dificultades. Debido a su relevancia terapéutica, esta revisión profundiza en la frontera entre los medicamentos y los productos sanitarios, y se diferencia de aquellas presentaciones en que medicamentos y productos sanitarios se usan de manera conjunta, sin constituir frontera. Establecer unas definiciones actualizadas, fomentar la transparencia en el sector y prevenir los conflictos de interés, debe motivar a los agentes implicados a la revisión periódica de una normativa en un campo sometido a constante evolución y desarrollo tecnológico.(AU)


Medical devices cover a wide range of products essential for healthcare. In 2017 a new European regulation covering them was approved that fully applies from 2021 onwards. In it, their legal definition, classification, conformity assessment procedures, requirements for the clinical investigations that asses their safety and/or performance, and European database are specified. Despite the efforts for systematizing the legal definition of medical device in the new regulation, the determination of the legal status of devices known as ‘borderline products’, for which different regulations may apply (like in the borderline with food supplements, cosmetics, personal care products, biocides, personal protective equipment and consumer products), is not without difficulties. On account of their therapeutic significance, this review delves into the borderline between medicinal products and medical devices, and differentiates them from presentations where medicinal products and medical devices are used in combination, without constituting a borderline. Establishing updated definitions, promoting transparency in the sector and preventing conflicts of interest should motivate all stakeholders to the periodic review of the regulation in a field in continuous technological evolution and development.(AU)

RESUMO

BACKGROUND: The Peucedanum genus is the backbone member of Apiaceae, with many economically and medically important plants. Although the previous studies on Peucedanum provide us with a good research basis, there are still unclear phylogenetic relationships and many taxonomic problems in Peucedanum, and a robust phylogenetic framework of this genus still has not been obtained, which severely hampers the improvement and revision of taxonomic system for this genus. The plastid genomes possessing more variable characters have potential for reconstructing a robust phylogeny in plants. RESULTS: In the current study, we newly sequenced and assembled seven Peucedanum plastid genomes. Together with five previously published plastid genomes of Peucedanum, we performed a comprehensively comparative analyses for this genus. Twelve Peucedanum plastomes were similar in terms of genome structure, codon bias, RNA editing sites, and SSRs, but varied in genome size, gene content and arrangement, and border of SC/IR. Fifteen mutation hotspot regions were identified among plastid genomes that can serve as candidate DNA barcodes for species identification in Peucedanum. Our phylogenetic analyses based on plastid genomes generated a phylogeny with high supports and resolutions for Peucedanum that robustly supported the non-monophyly of genus Peucedanum. CONCLUSION: The plastid genomes of Peucedanum showed both conservation and diversity. The plastid genome data were efficient and powerful for improving the supports and resolutions of phylogeny for the complex Peucedanum genus. In summary, our study provides new sights into the plastid genome evolution, taxonomy, and phylogeny for Peucedanum species.

RESUMO

En el más reciente número de esta revista se publicó el estudio titulado "Lesiones papilares de mama: estudio clínico-patológico y sobrepronóstico en 144 casos de Medellín, Colombia", donde se hace un excelente acercamiento sobre este tipo de lesiones. Se conoce que las lesiones papilares de la mama son entidades poco frecuentes en la práctica cotidiana, con una representación del 10% de las entidades benignas y solo un 1% de las entidades malignas. Su manifestación clínica habitual es la secreción serosanguinolenta, unilateral, sin masas palpables y en los estudios de imagen suelen mostrarse como lesiones únicas o múltiples de localización retroareolar. El diagnostico anatomopatologico no es sencillo en estudios por punción, bien sea con aguja fina o por aguja gruesa y, por lo general, se requiere de la escisión de la lesión para obtener un diagnóstico más certero.

RESUMO

BACKGROUND: Elymus breviaristatus and Elymus sinosubmuticus are perennial herbs, not only morphologically similar but also sympatric distribution. The genome composition of E. sinosubmuticus has not been reported, and the relationship between E. sinosubmuticus and E. breviaristatus is still controversial. We performed artificial hybridization, genomic in situ hybridization, and phylogenetic analyses to clarify whether the two taxa were the same species. RESULTS: The high frequency bivalent (with an average of 20.62 bivalents per cell) at metaphase I of pollen mother cells of the artificial hybrids of E. breviaristatus (StYH) × E. sinosubmuticus was observed. It illustrated that E. sinosubmuticus was closely related to E. breviaristatus. Based on genomic in situ hybridization results, we confirmed that E. sinosubmuticus was an allohexaploid, and the genomic constitution was StYH. Phylogenetic analysis results also supported that this species contained St, Y, and H genomes. In their F1 hybrids, pollen activity was 53.90%, and the seed setting rate was 22.46%. Those indicated that the relationship between E. sinosubmuticus and E. breviaristatus is intersubspecific rather than interspecific, and it is reasonable to treated E. sinosubmuticus as the subspecies of E. breviaristatus. CONCLUSIONS: In all, the genomic constitutions of E. sinosubmuticus and E. breviaristatus were StYH, and they are species in the genus Campeiostachys. Because E. breviaristatus was treated as Campeistachys breviaristata, Elymus sinosubmuticus should be renamed Campeiostachys breviaristata (Keng) Y. H. Zhou, H. Q. Zhang et C. R. Yang subsp. sinosubmuticus (S. L. Chen) Y. H. Zhou, H. Q. Zhang et L. Tan.

RESUMO

Music style is one of the important labels for music classification, and the current music style classification methods extract features such as rhythm and timbre of music and use classifiers to achieve classification. The classification accuracy is not only affected by the classifier but also limited by the effect of music feature extraction, which leads to poor classification accuracy and stability. In response to the abovementioned defects, a deep-learning-based music style classification method will be studied. The music signal is framed using filters and Hamming windows, and the MFCC coefficient features of music are extracted by discrete Fourier transform. A convolutional recurrent neural network structure combining CNN and RNN is designed and trained to determine the parameters to achieve music style classification. Analysis of the simulation experimental data shows that the classification accuracy of the studied classification method is at least 93.3%, and the classification time overhead is significantly reduced, the classification results are stable, and the results are reliable.

RESUMO

Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-TOF MS) has proved effective for the identification of many arthropods. A total of 432 termite specimens were collected in Mali, Cote d'Ivoire, Togo, Senegal, Switzerland and France. Morphologically, 22 species were identified, including Ancistrotermes cavithorax, Amitermes evuncifer, Cryptotermes brevis, Cubitermes orthognathus, Kalotermes flavicollis, Macrotermes bellicosus, Macrotermes herus, Macrotermes ivorensis, Macrotermes subhyalinus, Microcerotermes parvus, Microtermes sp., Odontotermes latericius, Procubitermes sjostedti, Promirotermes holmgreni, Reticulitermes grassei, Reticulitermes lucifugus, Reticulitermes santonensis, Trinervitermes geminatus, Trinervitermes occidentalis, Trinervitermes togoensis, Trinervitermes sp., Trinervitermes trinervoides and Trinervitermes trinervius. Analysis of MALDI-TOF MS spectra profiles from termites revealed that all were of high quality, with intra-species reproducibility and inter-species specificity. Blind testing of the spectra of 389 termites against our updated database with the spectra of 43 specimens of different termite species revealed that all were correctly identified with log score values (LSVs) ranging from 1.65 to 2.851, mean 2.290 ± 0.225, median 2.299, and 98.4% (383) had LSVs > 1.8. This study is the first on the use of MALDI-TOF for termite identification and shows its importance as a tool for arthropod taxonomy and reinforces the idea that MALDI-TOF MS is a promising tool in the field of entomology.

RESUMO

BACKGROUND: Salvia macrosiphon is an aromatic perennial species of Lamiaceae family that grows naturally in different parts of Iran. This herb is widely used in folk and modern medicine. Although in Flora Iranica and Flora of Iran, no infraspecific taxonomic rank has been detected for S. macrosiphon, some infraspecific taxonomic ranks have been reported. In the current study, we evaluated the genetic diversity and structure of 11 populations of this species to detect inter and intrapopulation genetic diversity and to survey the possibility of infraspecific taxonomic ranks in this species. METHODS AND RESULTS: We utilized the modified C-TAB protocol for DNA extraction and amplified the genomes using several SCoT molecular markers. We calculated of genetic diversity and polymorphism parameters using GenAlex 6.4, Geno-Dive ver.2, PopGene, PopART and Structure 2.3.4. The parameters of genetic polymorphism differed between the populations. Moreover, a low rate of gene flow supported a moderate level of population's genetic diversity and differentiation. According to haplotypes network (TCS) analysis, a high level of genetic mutation has occurred among the individuals of some populations leading to high intrapopulation diversity. On the basis of structure analysis and Nei's genetic distance, the examined populations were classified into four genotypes. CONCLUSIONS: The clustering pattern of the populations in each group was not related to geographical distance or phytogeography. It seems that the wide geographic distribution, a small gene flow rate and the occurrence of a high level of genetic mutation lead to infraspecific genetic differentiation in the species and we suppose some infraspecific ranks exist for it.

RESUMO

Deep neural networks (DNNs) have been recently proposed for quartet tree phylogeny estimation. Here, we present a study evaluating recently trained DNNs in comparison to a collection of standard phylogeny estimation methods on a heterogeneous collection of datasets simulated under the same models that were used to train the DNNs, and also under similar conditions but with higher rates of evolution. Our study shows that using DNNs with quartet amalgamation is less accurate than several standard phylogeny estimation methods we explore (e.g., maximum likelihood and maximum parsimony). We further find that simple standard phylogeny estimation methods match or improve on DNNs for quartet accuracy, especially, but not exclusively, when used in a global manner (i.e., the tree on the full dataset is computed and then the induced quartet trees are extracted from the full tree). Thus, our study provides evidence that a major challenge impacting the utility of current DNNs for phylogeny estimation is their restriction to estimating quartet trees that must subsequently be combined into a tree on the full dataset. In contrast, global methods (i.e., those that estimate trees from the full set of sequences) are able to benefit from taxon sampling, and hence have higher accuracy on large datasets.

RESUMO

BACKGROUND: Nurse researchers are well poised to study the connection of the microbiome to health and disease. Evaluating published microbiome results can assist with study design and hypothesis generation. OBJECTIVES: This article aims to present and define important analysis considerations in microbiome study planning and to identify genera shared across studies despite methodological differences. This methods article will highlight a workflow that the nurse scientist can use to combine and evaluate taxonomy tables for microbiome study or research proposal planning. METHODS: We compiled taxonomy tables from 13 published gut microbiome studies that had used Ion Torrent sequencing technology. We searched for studies that had amplified multiple hypervariable (V) regions of the 16S rRNA gene when sequencing the bacteria from healthy gut samples. RESULTS: We obtained 15 taxonomy tables from the 13 studies, comprised of samples from four continents and eight V regions. Methodology among studies was highly variable, including differences in V regions amplified, geographic location, and population demographics. Nevertheless, of the 354 total genera identified from the 15 data sets, 25 were shared in all V regions and the four continents. When relative abundance differences across the V regions were compared, Dorea and Roseburia were statistically different. Taxonomy tables from Asian subjects had increased average abundances of Prevotella and lowered abundances of Bacteroides compared with the European, North American, and South American study subjects. DISCUSSION: Evaluating taxonomy tables from previously published literature is essential for study planning. The genera found from different V regions and continents highlight geography and V region as important variables to consider in microbiome study design. The 25 shared genera across the various studies may represent genera commonly found in healthy gut microbiomes. Understanding the factors that may affect the results from a variety of microbiome studies will allow nurse scientists to plan research proposals in an informed manner. This work presents a valuable framework for future cross-study comparisons conducted across the globe.

RESUMO

Mosquitoes (Diptera: Culicidae) are considered the group of insects that most impacts human health. Land use change, conversion of conserved sites into agricultural environments, urbanization, defaunation, and introduction of domestic animals can affect mosquito diversity positively or negatively, increasing the risk of transmission of zoonotic diseases. Here, we describe the diversity of adult mosquitoes in two environments (deciduous forest and anthropized zone) over 2 yr (2014-2016), using eight CDC traps at each site in three climatic seasons (rainy, cold, and dry). We captured 795 individuals belonging to 22 species. We constructed rank-abundance curves to determine spatial and temporal changes in the mosquito communities. We measured alpha diversity using the Shannon index (H'), Shannon exponential (eH) and Simpson dominance (Ds), and beta diversity using Jaccard's coefficient of similarity (Ij). The most abundant species were Culex quinquefasciatus (40.5%), Culex coronator (18.3%), and Anopheles pseudopunctipennis (12.4%). The highest mosquito diversity was in the deciduous forest during the rainy season. Beta diversity analysis showed that species overlap varied among climatic seasons, with the sites sharing 65% species during the rainy season, but only 33% of species during the dry season. We found differences in the diversity of mosquitoes at the two sites, and the mosquito assemblage of the anthropized zone was significantly different from that of the deciduous forest.
