A template wizard for the cocreation of machine-readable data-reporting to harmonize the evaluation of (nano)materials.

Making research data findable, accessible, interoperable and reusable (FAIR) is typically hampered by a lack of skills in technical aspects of data management by data generators and a lack of resources. We developed a Template Wizard for researchers to easily create templates suitable for consistently capturing data and metadata from their experiments. The templates are easy to use and enable the compilation of machine-readable metadata to accompany data generation and align them to existing community standards and databases, such as eNanoMapper, streamlining the adoption of the FAIR principles. These templates are citable objects and are available as online tools. The Template Wizard is designed to be user friendly and facilitates using and reusing existing templates for new projects or project extensions. The wizard is accompanied by an online template validator, which allows self-evaluation of the template (to ensure mapping to the data schema and machine readability of the captured data) and transformation by an open-source parser into machine-readable formats, compliant with the FAIR principles. The templates are based on extensive collective experience in nanosafety data collection and include over 60 harmonized data entry templates for physicochemical characterization and hazard assessment (cell viability, genotoxicity, environmental organism dose-response tests, omics), as well as exposure and release studies. The templates are generalizable across fields and have already been extended and adapted for microplastics and advanced materials research. The harmonized templates improve the reliability of interlaboratory comparisons, data reuse and meta-analyses and can facilitate the safety evaluation and regulation process for (nano) materials.

Health communication and shared decision-making between nurses and older adults in community setting: An integrative review.

AIM: To explore the role of health communication in Shared Decision-Making (SDM) between nursing staff and older people in the community setting. BACKGROUND: Society and healthcare services are marked by an exponentially ageing population, leading to a significant proportion of patients being older adults with highly demanding care needs. Scientific literature supports shared decision-making as a process that engages patients in their care. However, the increasing use of technology and the consequences of the COVID-19 pandemic have influenced how nurses communicate with older patients. Therefore, it is crucial to understand how to develop health communication to reach effective, shared decision-making processes. METHODS: Whittemore and Knafl's integrative review method, the literature search comprised five databases: PubMed, CINALH, Web of Science, Scopus and PsycINFO. RESULTS: The 12 included studies were synthesised into three study patterns: (1) nurse-older patient health communication relationship, (2) older patients' perspectives and (3) nontherapeutic communication in end-of-life care. CONCLUSION: This review underscored the crucial role of effective health communication in shaping SDM dynamics between nursing staff and older people in the community setting. Key elements included transparent information exchange, establishing trust and maintaining communication channels with informal caregiving networks. SDM actions were aligned with preserving older people's autonomy, but communication challenges persisted, particularly in end-of-life situations. Advanced care planning was recommended to address these shortcomings and improve communication among older people, healthcare professionals and families. IMPLICATIONS: Implementing educational measures based on verbal and nonverbal health communication in nursing training could be beneficial. Nursing research could continue to develop and refine specific communication strategies adapted to the social determinants of health for diverse clinical situations regarding older adults in the community setting. REPORTING METHOD: The authors have adhered to relevant EQUATOR guidelines through the PRISMA 2020 checklist. No Patient or Public Contribution.

[Multiform exudative erythema caused by hydroxychloroquine, diagnosed by epicutaneous tests: A case report]. / Eritema exudativo multiforme provocado por hidroxicloroquina, diagnosticado mediante pruebas epicutáneas: reporte de un caso.

INTRODUCTION: Multiform exudative erythema is a rare delayed hypersensitivity reaction associated with medications. The manifestations caused by hydroxychloroquine are exceptional; however, due to the increase in its prescription due to the recent SARS-CoV-2 pandemic, adverse reactions have been exacerbated. CASE REPORT: A 60-year-old female patient, who attended the Emergency Department for a picture of erythematous rash of one week of evolution, with involvement of the trunk, face and palms of the hands. Laboratory studies reported: leukocytosis with neutrophilia and lymphopenia, without eosinophilia or abnormal liver enzymes. The lesions continued to descend towards her extremities, with subsequent desquamation. She was prescribed prednisone 15 mg/24 h for three days, tapering to 10 mg/24 h, until her new assessment, in addition to antihistamines. Two days later, new macular lesions appeared in the presternal area and on the oral mucosa. Control laboratory studies did not show alterations. Skin biopsy reported: vacuolar interface dermatitis with spongiosis and parakeratosis, compatible with erythema multiforme. Epicutaneous tests were carried out with meloxicam and 30% hydroxychloroquine in water and vaseline, occluded for two days and interpreted at 48 and 96 hours, with a positive result for the latter. The diagnosis of multiform exudative erythema due to hydroxychloroquine was established. CONCLUSIONS: This study confirms the efficacy of patch tests in patients with delayed hypersensitivity reactions to hydroxychloroquine.

The State of the Art and Challenges of In Vitro Methods for Human Hazard Assessment of Nanomaterials in the Context of Safe-by-Design.

The Safe-by-Design (SbD) concept aims to facilitate the development of safer materials/products, safer production, and safer use and end-of-life by performing timely SbD interventions to reduce hazard, exposure, or both. Early hazard screening is a crucial first step in this process. In this review, for the first time, commonly used in vitro assays are evaluated for their suitability for SbD hazard testing of nanomaterials (NMs). The goal of SbD hazard testing is identifying hazard warnings in the early stages of innovation. For this purpose, assays should be simple, cost-effective, predictive, robust, and compatible. For several toxicological endpoints, there are indications that commonly used in vitro assays are able to predict hazard warnings. In addition to the evaluation of assays, this review provides insights into the effects of the choice of cell type, exposure and dispersion protocol, and the (in)accurate determination of dose delivered to cells on predictivity. Furthermore, compatibility of assays with challenging advanced materials and NMs released from nano-enabled products (NEPs) during the lifecycle is assessed, as these aspects are crucial for SbD hazard testing. To conclude, hazard screening of NMs is complex and joint efforts between innovators, scientists, and regulators are needed to further improve SbD hazard testing.

The Role of S. cerevisiae Sub1/PC4 in Transcription Elongation Depends on the C-Terminal Region and Is Independent of the ssDNA Binding Domain.

Saccharomyces cerevisiae Sub1 (ScSub1) has been defined as a transcriptional stimulatory protein due to its homology to the ssDNA binding domain (ssDBD) of human PC4 (hPC4). Recently, PC4/Sub1 orthologues have been elucidated in eukaryotes, prokaryotes, and bacteriophages with functions related to DNA metabolism. Additionally, ScSub1 contains a unique carboxyl-terminal region (CT) of unknown function up to date. Specifically, it has been shown that Sub1 is required for transcription activation, as well as other processes, throughout the transcription cycle. Despite the progress that has been made in understanding the mechanism underlying Sub1's functions, some questions remain unanswered. As a case in point: whether Sub1's roles in initiation and elongation are differentially predicated on distinct regions of the protein or how Sub1's functions are regulated. Here, we uncover some residues that are key for DNA-ScSub1 interaction in vivo, localized in the ssDBD, and required for Sub1 recruitment to promoters. Furthermore, using an array of genetic and molecular techniques, we demonstrate that the CT region is required for transcription elongation by RNA polymerase II (RNAPII). Altogether, our data indicate that Sub1 plays a dual role during transcription-in initiation through the ssDBD and in elongation through the CT region.

Safe(r) by design guidelines for the nanotechnology industry.

Expectations for safer and sustainable chemicals and products are growing to comply with the United Nations and European strategies for sustainability. The application of Safe(r) by Design (SbD) in nanotechnology implies an iterative process where functionality, human health and safety, environmental and economic impact and cost are assessed and balanced as early as possible in the innovation process and updated at each step. The EU H2020 NanoReg2 project was the first European project to implement SbD in six companies handling and/or manufacturing nanomaterials (NMs) and nano-enabled products (NEP). The results from this experience have been used to develop these guidelines on the practical application of SbD. The SbD approach foresees the identification, estimation, and reduction of human and environmental risks as early as possible in the development of a NM or NEP, and it is based on three pillars: (i) safer NMs and NEP; (ii) safer use and end of life and (iii) safer industrial production. The presented guidelines include a set of information and tools that will help deciding at each step of the innovation process whether to continue, apply SbD measures or carry out further tests to reduce uncertainty. It does not intend to be a prescriptive protocol where all suggested steps have to be followed to achieve a SbD NM/NEP or process. Rather, the guidelines are designed to identify risks at an early state and information to be considered to identify those risks. Each company adapts the approach to its specific needs and circumstances as company decisions influence the way forward.

[Peculiarities of allergy to plant foods in South-Eastern Spain]. / Peculiaridades de la alergia a los alimentos vegetales en el sureste de España.

Allergy to fruits and vegetables is the most common primary food allergy in Mediterranean countries, especially the lipid transfer proteins (LTPs) syndrome. This study is the first research that studies multiple clinical, allergological and therapeutics characteristics of allergies to plants in the South-East of Spain, and assessing whether these characteristics differ in emergency room or outpatient clinic. This is a prospective study of patients who consult for the first time for allergy to vegetables at Granada, Spain. We record demographic data, symptoms, allergological study and indicated therapy. The characteristics obtained agree with the current bibliographic except the higher prevalence than other areas of positive sensitization of Pru p 3, Cor a 9 and Ara h 9, which predisposes to severe allergic reactions. We conclude: Allergy to plant food in Granada is a more severe phenotype than other geographic areas from Spain, especially in young adults sensitized by different LTPs and pollinosis to olive pollen.

Regulation of Eukaryotic RNAPs Activities by Phosphorylation.

Evolutionarily conserved kinases and phosphatases regulate RNA polymerase II (RNAPII) transcript synthesis by modifying the phosphorylation status of the carboxyl-terminal domain (CTD) of Rpb1, the largest subunit of RNAPII. Proper levels of Rpb1-CTD phosphorylation are required for RNA co-transcriptional processing and to coordinate transcription with other nuclear processes, such as chromatin remodeling and histone modification. Whether other RNAPII subunits are phosphorylated and influences their role in gene expression is still an unanswered question. Much less is known about RNAPI and RNAPIII phosphorylation, whose subunits do not contain functional CTDs. However, diverse studies have reported that several RNAPI and RNAPIII subunits are susceptible to phosphorylation. Some of these phosphorylation sites are distributed within subunits common to all three RNAPs whereas others are only shared between RNAPI and RNAPIII. This suggests that the activities of all RNAPs might be finely modulated by phosphorylation events and raises the idea of a tight coordination between the three RNAPs. Supporting this view, the transcription by all RNAPs is regulated by signaling pathways that sense different environmental cues to adapt a global RNA transcriptional response. This review focuses on how the phosphorylation of RNAPs might regulate their function and we comment on the regulation by phosphorylation of some key transcription factors in the case of RNAPI and RNAPIII. Finally, we discuss the existence of possible common mechanisms that could coordinate their activities.

Integrative approach in a safe by design context combining risk, life cycle and socio-economic assessment for safer and sustainable nanomaterials.

Moving towards safe and sustainable innovations is an international policy ambition. In the on-hand manuscript, a concept combining safe by design and sustainability was implemented through the integration of human and environmental risk assessment, life cycle assessment as well as an assessment of the economic viability. The result is a nested and iterative process in form of a decision tree that integrates these three elements in order to achieve sustainable, safe and competitive materials, products or services. This approach, embedded into the stage-gate-model for safe by design, allows to reduce the uncertainty related to the assessment of risks and impacts by improving the quality of the data collected along each stage. In the second part of the manuscript, the application is shown for a case study dealing with the application of nanoparticles for Li-Ion batteries. One of the general conclusions out of this case study is that data gaps are a key aspect in view of the reliability of the results.

Indoor dispersion of airborne nano and fine particles: Main factors affecting spatial and temporal distribution in the frame of exposure modeling.

A particle exposure experiment inside a large climate-controlled chamber was conducted. Data on spatial and temporal distribution of nanoscale and fine aerosols in the range of mobility diameters 8-600 nm were collected with high resolution, for sodium chloride, fluorescein sodium, and silica particles. Exposure scenarios studied included constant and intermittent source emissions, different aggregation conditions, high (10 h-1 ) and low (3.5 h-1 ) air exchange rates (AERs) corresponding to chamber Reynolds number, respectively, equal to 1 × 105 and 3 × 104 . Results are presented and analyzed to highlight the main determinants of exposure and to determine whether the assumptions underlying two-box models hold under various scenarios. The main determinants of exposure found were the source generation rate and the ventilation rate. The effect of particles nature was indiscernible, and the decrease of airborne total number concentrations attributable to surface deposition was estimated lower than 2% when the source was active. A near-field/far-field structure of aerosol concentration was always observed for the AER = 10 h-1 but for AER = 3.5 h-1 , a single-field structure was found. The particle size distribution was always homogeneous in space but a general shift of particle diameter (-8% to +16%) was observed between scenarios in correlation with the AER and with the source position, presumably largely attributable to aggregation.

Source specific exposure and risk assessment for indoor aerosols.

Poor air quality is a leading contributor to the global disease burden and total number of deaths worldwide. Humans spend most of their time in built environments where the majority of the inhalation exposure occurs. Indoor Air Quality (IAQ) is challenged by outdoor air pollution entering indoors through ventilation and infiltration and by indoor emission sources. The aim of this study was to understand the current knowledge level and gaps regarding effective approaches to improve IAQ. Emission regulations currently focus on outdoor emissions, whereas quantitative understanding of emissions from indoor sources is generally lacking. Therefore, specific indoor sources need to be identified, characterized, and quantified according to their environmental and human health impact. The emission sources should be stored in terms of relevant metrics and statistics in an easily accessible format that is applicable for source specific exposure assessment by using mathematical mass balance modelings. This forms a foundation for comprehensive risk assessment and efficient interventions. For such a general exposure assessment model we need 1) systematic methods for indoor aerosol emission source assessment, 2) source emission documentation in terms of relevant a) aerosol metrics and b) biological metrics, 3) default model parameterization for predictive exposure modeling, 4) other needs related to aerosol characterization techniques and modeling methods. Such a general exposure assessment model can be applicable for private, public, and occupational indoor exposure assessment, making it a valuable tool for public health professionals, product safety designers, industrial hygienists, building scientists, and environmental consultants working in the field of IAQ and health.
