Identification of Novel Bacterial Microproteins Encoded by Small Open Reading Frames Using a Computational Proteogenomics Workflow.

Genome annotation has historically ignored small open reading frames (smORFs), which encode a class of proteins shorter than 100 amino acids, collectively referred to as microproteins. This cutoff was established to avoid thousands of false positives due to limitations of pure genomics pipelines. Proteogenomics, a computational approach that combines genomics, transcriptomics, and proteomics, makes it possible to accurately identify these short sequences by overlaying different levels of omics evidence. In this chapter, we showcase the use of µProteInS, a bioinformatics pipeline developed for the identification of unannotated microproteins encoded by smORFs in bacteria. The workflow covers all the steps from quality control and transcriptome assembly to the scoring and post-processing of mass spectrometry data. Additionally, we provide an example on how to apply the pipeline's machine learning method to identify high-confidence spectra and pinpoint the most reliable identifications from large datasets.

Screening of Candida spp. in wastewater in Brazil during COVID-19 pandemic: workflow for monitoring fungal pathogens.

Fungal diseases are often linked to poverty, which is associated with poor hygiene and sanitation conditions that have been severely worsened by the COVID-19 pandemic. Moreover, COVID-19 patients are treated with Dexamethasone, a corticosteroid that promotes an immunosuppressive profile, making patients more susceptible to opportunistic fungal infections, such as those caused by Candida species. In this study, we analyzed the prevalence of Candida yeasts in wastewater samples collected to track viral genetic material during the COVID-19 pandemic and identified the yeasts using polyphasic taxonomy. Furthermore, we investigated the production of biofilm and hydrolytic enzymes, which are known virulence factors. Our findings revealed that all Candida species could form biofilms and exhibited moderate hydrolytic enzyme activity. We also proposed a workflow for monitoring wastewater using Colony PCR instead of conventional PCR, as this technique is fast, cost-effective, and reliable. This approach enhances the accurate taxonomic identification of yeasts in environmental samples, contributing to environmental monitoring as part of the One Health approach, which preconizes the monitoring of possible emergent pathogenic microorganisms, including fungi.

NP3 MS Workflow: An Open-Source Software System to Empower Natural Product-Based Drug Discovery Using Untargeted Metabolomics.

Natural products (or specialized metabolites) are historically the main source of new drugs. However, the current drug discovery pipelines require miniaturization and speeds that are incompatible with traditional natural product research methods, especially in the early stages of the research. This article introduces the NP3 MS Workflow, a robust open-source software system for liquid chromatography-tandem mass spectrometry (LC-MS/MS) untargeted metabolomic data processing and analysis, designed to rank bioactive natural products directly from complex mixtures of compounds, such as bioactive biota samples. NP3 MS Workflow allows minimal user intervention as well as customization of each step of LC-MS/MS data processing, with diagnostic statistics to allow interpretation and optimization of LC-MS/MS data processing by the user. NP3 MS Workflow adds improved computing of the MS2 spectra in an LC-MS/MS data set and provides tools for automatic [M + H]+ ion deconvolution using fragmentation rules; chemical structural annotation against MS2 databases; and relative quantification of the precursor ions for bioactivity correlation scoring. The software will be presented with case studies and comparisons with equivalent tools currently available. NP3 MS Workflow shows a robust and useful approach to select bioactive natural products from complex mixtures, improving the set of tools available for untargeted metabolomics. It can be easily integrated into natural product-based drug-discovery pipelines and to other fields of research at the interface of chemistry and biology.

Replacement of unsatisfactory ceramic veneers with the aid of a digital workflow.

This case report focuses on the replacement of ceramic laminate veneers with suboptimal marginal fit and design, employing a digital workflow and CAD-CAM technology. The patient, a woman in her 30s, expressed concerns about the appearance and hygiene challenges of her existing veneers. A comprehensive assessment, including clinical examination, facial photographs and intraoral scanning, was conducted. Utilising CAD software, facial photographs and 3D models merged to create a digital wax-up, crucial in designing suitable veneers and addressing issues like overcontouring and a poor emergence profile. Following the removal of old veneers, a mock-up was performed and approved. Preparations ensured space for restorations with well-defined margins. The final restorations, milled with Leucite-reinforced vitreous ceramic, were cemented. At the 1 year follow-up, improved aesthetics, gingival health and functional restorations were observed. This report highlights the efficacy of digital workflows in achieving consistent and aesthetically pleasing outcomes in ceramic laminate veneer replacement.

The role of intraoral scanning in the fully digital workflow for post and core restorations: A scoping review.

OBJECTIVE: This scoping review aimed to map the literature on the utilization of intraoral scanners (IOS) in fabricating post and core restorations. DATA: The study protocol is available at https://osf.io/ja9xh/. This scoping review followed Joanna Briggs Institute guidelines, and reporting was based on the checklist proposed by PRISMA-ScR. SOURCES: Searches were conducted in PubMed/MEDLINE, Web of Science, Scopus, and grey literature up to August 2023. RESULTS: A total of 455 studies were identified. After screening, 16 studies were deemed suitable for scoping review. Of these, 13 were in vitro studies, two were case reports, and one was a clinical study. Different IOS systems for scanning post spaces were evaluated, with Trios being most prevalent, followed by Prismescan. While most studies did not use any intraoral scanning devices, five studies reported the use of scan posts. Results regarding retention favored fully digital workflows. However, results about the adaptation and accuracy varied between included studies, highlighting the importance of standardized approaches. Future clinical studies should encompass variations in IOS systems, post space depths, scanner depth of field, light conditions, scan post utilization, operator experience, scanning time and strategy, and direct comparison with conventional techniques. CONCLUSION: IOS is increasingly important in capturing digital impressions for post spaces and provides valuable insights for clinicians and researchers. Although included studies, primarily in vitro, demonstrated promising results for the utilization of IOS systems in fully digital workflows for post and core restorations, further well-conducted studies, particularly clinical trials, are recommended due to data heterogeneity and limitations. CLINICAL SIGNIFICANCE: This mapping highlights the potential of modern IOS in fully digital workflows for post and core restorations. Despite promising results, challenges related to different variables associated with IOS require careful consideration. Standardization and additional clinical validation are essential for optimize IOS benefits in post and core restorations.

Examining evolutionary scale modeling-derived different-dimensional embeddings in the antimicrobial peptide classification through a KNIME workflow.

Molecular features play an important role in different bio-chem-informatics tasks, such as the Quantitative Structure-Activity Relationships (QSAR) modeling. Several pre-trained models have been recently created to be used in downstream tasks, either by fine-tuning a specific model or by extracting features to feed traditional classifiers. In this regard, a new family of Evolutionary Scale Modeling models (termed as ESM-2 models) was recently introduced, demonstrating outstanding results in protein structure prediction benchmarks. Herein, we studied the usefulness of the different-dimensional embeddings derived from the ESM-2 models to classify antimicrobial peptides (AMPs). To this end, we built a KNIME workflow to use the same modeling methodology across experiments in order to guarantee fair analyses. As a result, the 640- and 1280-dimensional embeddings derived from the 30- and 33-layer ESM-2 models, respectively, are the most valuable  since statistically better performances were achieved by the QSAR models built from them. We also fused features of the different ESM-2 models, and it was concluded that the fusion contributes to getting better QSAR models than using features of a single ESM-2 model. Frequency studies revealed that only a portion of the ESM-2 embeddings is valuable for modeling tasks since between 43% and 66% of the features were never used. Comparisons regarding state-of-the-art deep learning (DL) models confirm that when performing methodologically principled studies in the prediction of AMPs, non-DL based QSAR models yield comparable-to-superior performances to DL-based QSAR models. The developed KNIME workflow is available-freely at https://github.com/cicese-biocom/classification-QSAR-bioKom. This workflow can be valuable to avoid unfair comparisons regarding new computational methods, as well as to propose new non-DL based QSAR models.

Integrative open workflow for confident annotation and molecular networking of metabolomics MSE/DIA data.

Liquid chromatography coupled with high-resolution mass spectrometry data-independent acquisition (LC-HRMS/DIA), including MSE, enable comprehensive metabolomics analyses though they pose challenges for data processing with automatic annotation and molecular networking (MN) implementation. This motivated the present proposal, in which we introduce DIA-IntOpenStream, a new integrated workflow combining open-source software to streamline MSE data handling. It provides 'in-house' custom database construction, allows the conversion of raw MSE data to a universal format (.mzML) and leverages open software (MZmine 3 and MS-DIAL) all advantages for confident annotation and effective MN data interpretation. This pipeline significantly enhances the accessibility, reliability and reproducibility of complex MSE/DIA studies, overcoming previous limitations of proprietary software and non-universal MS data formats that restricted integrative analysis. We demonstrate the utility of DIA-IntOpenStream with two independent datasets: dataset 1 consists of new data from 60 plant extracts from the Ocotea genus; dataset 2 is a publicly available actinobacterial extract spiked with authentic standard for detailed comparative analysis with existing methods. This user-friendly pipeline enables broader adoption of cutting-edge MS tools and provides value to the scientific community. Overall, it holds promise for speeding up metabolite discoveries toward a more collaborative and open environment for research.

Disparities in the protagonism of oral health teams in the work process of Primary Healthcare / Disparidades do protagonismo das equipes de saúde bucal no processo de trabalho na APS

ABSTRACT OBJECTIVE Evaluate and compare the protagonism of Oral Health teams (OHt) in the teamwork process in Primary Healthcare (PHC) over five years and estimate the magnitude of disparities between Brazilian macro-regions. METHODS Ecological study that used secondary data extracted from the Sistema de Informação em Saúde para a Atenção Básica (SISAB - Health Information System for Primary Healthcare) from 2018 to 2022. Indicators were selected from a previously validated evaluative matrix, calculated from records in the Collective Activity Form on the degree of OHt's protagonism in team meetings and its degree of organization concerning the meeting agendas. A descriptive and amplitude analysis of the indicators' variation over time was carried out, and the disparity index was also calculated to estimate and compare the magnitude of differences between macro-regions in 2022. RESULTS In Brazil, between 3.06% and 4.04% of team meetings were led by OHt professionals. The Northeast and South regions had the highest (3.71% to 4.88%) and lowest proportions (1.21% to 2.48%), respectively. From 2018 to 2022, there was a reduction in the indicator of the "degree of protagonism of the OHt" in Brazil and macro-regions. The most frequent topics in meetings under OHt's responsibility were the work process (54.71% to 70.64%) and diagnosis and monitoring of the territory (33.49% to 54.48%). The most significant disparities between regions were observed for the indicator "degree of organization of the OHt concerning case discussion and singular therapeutic projects". CONCLUSIONS The protagonism of the OHt in the teamwork process in PHC is incipient and presents regional disparities, which challenges managers and OHt to break isolation and lack of integration, aiming to offer comprehensive and quality healthcare to the user of the Unified Health System (SUS).

CONCLUSÕES O protagonismo das eSB no processo de trabalho em equipe na APS é incipiente e apresenta disparidades regionais, o que desafia gestores e eSB para o rompimento do isolamento e da falta de integração, visando a oferta de atenção à saúde integral e de qualidade ao usuário do Sistema Único de Saúde (SUS).

Bridging the Gaps in Meta-Omic Analysis: Workflows and Reproducibility.

The past few years have seen significant advances in the study of complex microbial communities associated with the evolution of sequencing technologies and increasing adoption of whole genome shotgun sequencing methods over the once more traditional Amplicon-based methods. Although these advances have broadened the horizon of meta-omic analyses in planetary health, human health, and ecology from simple sample composition studies to comprehensive taxonomic and metabolic profiles, there are still significant challenges in processing these data. First, there is a widespread lack of standardization in data processing, including software choices and the ease of installing and running attendant software. This can lead to several inconsistencies, making comparing results across studies and reproducing original results difficult. We argue that these drawbacks are especially evident in metatranscriptomic analysis, with most analyses relying on ad hoc scripts instead of pipelines implemented in workflow managers. Additional challenges rely on integrating meta-omic data, since methods have to consider the biases in the library preparation and sequencing methods and the technical noise that can arise from it. Here, we critically discuss the current limitations in metagenomics and metatranscriptomics methods with a view to catalyze future innovations in the field of Planetary Health, ecology, and allied fields of life sciences. We highlight possible solutions for these constraints to bring about more standardization, with ease of installation, high performance, and reproducibility as guiding principles.

Development of a novel workflow method to characterize and validate clinical data quality acquired through the Veterinary Committee on Trauma registry.

OBJECTIVE: To generate and apply a novel workflow method to assess the quality of data from the Veterinary Committee on Trauma (VetCOT) registry. ANIMALS: Canine and feline trauma patient data entered by identified and verified Veterinary Trauma Centers into the VetCOT registry between April 2017-December 2018 were retrieved for analysis. METHODS: Analysis software (RVetQual) was created in the R programming language to compare 5,000 cases exported from the VetCOT registry with samples of original corresponding records from 6 veterinary trauma centers. In addition, an evaluation of the consistency and completeness of the trauma registry was conducted. RESULTS: The utilization of this analysis tool allowed an assessment of the VetCOT trauma registry. Some of the variables effecting the accuracy, consistency, and completeness of the VetCOT trauma registry were canine and feline age, weight, trauma time entered, and mismatches in blood glucose. However, the completeness of the database was minimally affected. CLINICAL RELEVANCE: RVetQual is an efficient, accessible, and adjustable tool that facilitates the assessment of the data quality of the VetCOT registry. Such an assessment can lead to improvement of the quality of information serving to guide further trauma patient care.

From Raw Data to FAIR Data: The FAIRification Workflow for Brazilian Tuberculosis Research.

Among the main factors that negatively influence the decision-making process, it is possible to highlight the low quality, availability, and integration of population health data. This study aims to highlight the difficulty of research based on tuberculosis data available in Brazil. The FAIR methodology is a solution for standardizing data and sharing information about the disease. All the main actors involved, including those who generate data and administrators of information systems, should be encouraged to know their strengths and weaknesses. Continuously fostering strategies to promote data quality is, therefore, a strong stimulus for strengthening national health information systems and can potentially benefit from recommendations on how to overcome the inherent limitations of these information systems. Data quality management in Brazilian tuberculosis information systems is still not carried out organized and systematically. According to the FAIR principles, the evaluation demonstrates only 37.75% of compliance.

Veneer tooth preparation utilizing a novel digital designed workflow: A case report.

OBJECTIVE: This article describes a technique to implement guided tooth preparation where the tooth is virtually prepared in the laboratory and preparation templates are created for chairside use. CLINICAL CONSIDERATIONS: Prior to any tooth preparation, patient records are acquired with an intra-oral scanner, both stump and final shades are selected, and digital photos are taken. These digital records are used in combination with digital laboratory tools to do the virtual preparation first, and then to provide chairside templates for guided tooth preparation. CONCLUSIONS: The traditional approach of tooth preparation has evolved from historically preparing a tooth without any pretreatment guidance to, more currently, preparing the tooth through a mock-up of the desired final restoration. The outcome of these traditional approaches is highly dependent on the operator's skills to produce a successful outcome, and often resulted in more tooth structure removal than necessary. However, CAD/CAM technology now offers a guided tooth approach to tooth preparation which minimizes tooth structure removal and provides an advantage to the beginner dentist. CLINICAL SIGNIFICANCE: This is a unique approach in digital restorative dentistry.

Experimental cystic echinococcosis as a proof of concept for the development of peptide-based vaccines following a novel rational workflow.

Vaccines are among the most important advances in medicine throughout the human history. However, conventional vaccines exhibit several drawbacks in terms of design and production costs. Peptide-based vaccines are attractive alternatives, since they can be designed mainly in silico, can be produced cheaply and safely, and are able to induce immune responses exclusively towards protective epitopes. Yet, a proper peptide design is needed, not only to generate peptide-specific immune responses, but also for them to recognize the native protein in the occurrence of a natural infection. Herein, we propose a rational workflow for developing peptide-based vaccines including novel steps that assure the cross-recognition of native proteins. In this regard, we increased the probability of generating efficient antibodies through the selection of linear B-cell epitopes free of post-translational modifications followed by analyzing the 3D-structure similarity between the peptide in-solution vs. within its parental native protein. As a proof of concept, this workflow was applied to a set of seven previously suggested potential protective antigens against the infection by Echinococcus granulosus sensu lato. Finally, two peptides were obtained showing the capacity to induce specific antibodies able to exert anti-parasite activities in different in vitro settings, as well as to provide significant protection in the murine model of secondary echinococcosis.

Full-mouth rehabilitation in a completely digital workflow using partially adhesive monolithic zirconia restorations.

OBJECTIVE: This clinical case describes a completely digital workflow using current digital technologies for a full-mouth adhesive rehabilitation with ultra-translucent multilayer zirconia restorations. CLINICAL CONSIDERATIONS: A healthy 60-year-old man with abfractions on all upper and lower molars and severe tooth wear underwent a full-mouth rehabilitation with laminate veneers and partial adhesive restorations. A proper zirconia bonding protocol was realized to provide a durable bond between the ultra-translucent zirconia and the resin cement. Furthermore, the implementation of a digital workflow enables the clinician to have an effective communication during treatment planning and simplify the clinical and laboratory procedures, providing the patient with long-term esthetic treatment and functional results. CONCLUSION: The implementation of a completely digital workflow and the use of ultra-translucent multilayer zirconia for indirect adhesive restorations can be an alternative with simplified and predictable procedures for patients with dental wear and teeth discolorations. CLINICAL SIGNIFICANCE: The digital workflow described is intended to facilitate the planning and execution of a full-mouth adhesive rehabilitation and demonstrates to clinicians a reliable zirconia bonding concept for minimally invasive anterior and posterior restorations.

Usado análisis cuantitativo utilizando estadística descriptiva y la análisis cualitativo basado en análisis de contenido y de la Fortalezas, Debilidades, Oportunidades, Amenazas. Resultados: el 44,4% de los hospitales cuenta con Centros de Evaluación de Tecnologías Sanitarias, mientras que el 91,7% de ellos tiene una Comisión de Estandarización de Productos de Salud formalmente constituída. Las variables observadas con mayor frecuencia: ausencia de procesos documentados, flujos indefinidos y falta de infraestructura. Conclusión: el proceso de incorporación de tecnologías ocurre de manera desigual. Los datos pueden contribuir a que la Empresa Brasileña de Servicios Hospitalarios reinicia estrategias e implemente acciones, a fin de apoyar a sus filiales en la constitución e implantación de estas instancias, fundamentales en el proceso de incorporación de tecnologías en el ámbito hospitalario.

CAD-CAM natural restorations-Reproducing nature using a digital workflow.

OBJECTIVES: Natural restorations combine digital workflow and shell technique to create CAD/CAM restorations with the form and texture of natural teeth. This case report describes an interdisciplinary digital workflow combined with CAD/CAM natural restorations to achieve the naturalness of an anterior rehabilitation. CLINICAL CONSIDERATIONS: A 38-year-old patient attended to the office with esthetic issues. An interdisciplinary treatment plan was conducted, which included periodontal surgery to recreate the gingival contour, associated with bleaching and manufacturing CAD/CAM ceramic veneers to return an optimal teeth surface texture and shape. CONCLUSIONS: The design and manufacturing of CAD/CAM natural restorations using a digital workflow allowed a predictable result and overcame the limitations of conventional shell technique. CLINICAL SIGNIFICANCE: Conventional shell technique is used to create restorations with the form and texture of natural teeth. This article presents a combination of the conventional shell technique with a digital workflow, facilitating the design and manufacturing of CAD/CAM natural restorations.
