El pasado día 21 de junio se publica en el BOE el Real Decreto 524/2023, de 20 de junio, por el que se aprueba la Norma Básica de Protección Civil. Esta nueva norma deroga, con un plazo de 4 años, otra norma fundametal para la Seguridad y Salud de los trabajadores, la Norma Básica de Autoproteción (Real Decreto 393/2007). Esta derogación en diferido genera una gran incertidumbre para los Técnicos/as de Prevención.

Objective: This study aimed to assess the prevalence of respiratory symptoms among informal waste pickers in Colombia and identify the contributing demographic, environmental, and occupational risk factors. Methods: A cross-sectional study was conducted with 179 informal waste pickers from four Colombian cities. Respiratory symptoms and demographic data were collected through questionnaires. Statistical methods including logistic regression, principal component analysis (PCA), Random Forest modelling, and K-means clustering were applied to identify predictors and patterns related to respiratory health. Results: The most frequently reported symptoms were cough (46.8%), phlegm (18.4%), and shortness of breath (19.6%). Logistic regression identified age as a significant predictor of respiratory symptoms, while Random Forest analysis highlighted cough as the strongest predictor, followed by age, race, and education level. K-means clustering revealed three groups, with older workers showing the highest prevalence of symptoms. PCA indicated that respiratory symptoms and demographic factors explained significant variance in health outcomes. Conclusions: Informal waste pickers in Colombia are at elevated risk for respiratory health issues, particularly older workers exposed to prolonged occupational hazards. Targeted interventions, including improved use of protective measures and policies addressing informal work conditions, are needed to mitigate these risks and improve workers’ health and safety.

Dirofilaria repens is the leading cause of subcutaneous (dogs) and subcutaneous/ocular dirofilariosis (humans) in the Old World. Despite its rapid geographical spread, driven by climate change, the emergence of new invasive vectors (Aedes albopictus) and growing interest in its study due to the emergence of new cases in areas previously free of the parasite, amongst other factors, scientific research into this pathogen remains limited. This study provides the first longitudinal bibliometric analysis of global research on D. repens (1955–2025). Data from Web of Science and Scopus were processed using PRISMA and RAMIBS protocols, resulting in a normalized corpus of 624 documents analyzed via science mapping techniques. The field exhibits a sustained annual growth rate of 3.79%, transitioning into an exponential expansion phase in 2011. While Italy retains historical leadership, spatial analysis confirms a research displacement towards Central and Eastern Europe (Germany, Poland). Thematic evolution reveals a structural shift from isolated clinical case reports to a multidisciplinary ecosystem dominated by molecular epidemiology, vector competence, and surveillance. Dirofilaria repens has gone from being a minor and neglected issue to having a significant number of reports and studies subject to interest in addressing the disease that results from its infection in different hosts. However, the intellectual structure exposes an operational fragmentation between clinical medicine and medical entomology. Future research must overcome national silos and integrate reservoir management with vector control, transforming the current reactive approach into a predictive preventive system aligned with the One Health framework.

A complete pipeline for systematic bibliometric mapping of occupational health and safety (OHS) evidence. Starting from reference files exported from major bibliographic databases such as Web of Science, Scopus, PubMed, Dimensions, EBSCO, and others, 'orisma' automates ingestion, deduplication, relevance filtering, occupational risk category extraction, bibliometric analysis, and report generation. The package is related to bibliometric science mapping and evidence synthesis workflows described by Aria and Cuccurullo (2017) , Westgate (2019) , and Lajeunesse (2016) , but adds a domain-specific occupational safety and health layer. The package implements three original bibliometric indicators: (1) the Worker-Risk Disconnection Index (WRDI), measuring the proportion of studies that characterise an occupational risk without including direct worker exposure data; (2) the Risk Category Saturation Index (RCS), measuring the relative over- or under-representation of each risk category relative to a uniform baseline; and (3) the Material-Gap Profile (MGP), measuring the ratio between a material's known hazard potential and its coverage in the occupational health literature. Two additional preventive intelligence indicators are provided: (4) the Abstract Sufficiency Score (ASS, 0-5), a cumulative hierarchical index of the preventively useful information contained in an abstract; and (5) the Bridge Article Score (0-5), identifying studies that simultaneously address technology, hazardous agent, worker population, exposure measurement, and preventive recommendations. Risk categories are extracted using a built-in occupational risk dictionary of 58 categories anchored in ISO 45001:2018, INSST, NIOSH, and EU-OSHA frameworks, organised in six blocks: Safety, Industrial Hygiene, Ergonomics, Psychosociology, Biological Hazards, and Emerging Technologies. The dictionary is user-extensible. Outputs include bilingual HTML reports, occupational risk sheets, priority reading rankings, guided extraction matrices for systematic review, and reproducibility certificates with MD5 hashes.

Objectives. Professionals in the perfume industry are routinely exposed to numerous chemical substances during olfactory evaluations, some of which may pose inhalation hazards. Existing qualitative risk assessment tools, such as Control of Substances Hazardous to Health (COSHH) Essentials, provide approximate estimates and may not be well suited to industries with highly specific exposure conditions like perfumery. This study evaluates the applicability and limitations of COSHH Essentials in perfume laboratories and proposes an improved qualitative framework tailored to perfumers' exposure scenarios. Methods. A total of 626 substances from a perfumer's palette were assessed using COSHH Essentials, which classifies substances into risk levels based on hazard, volatility and quantity. A complementary method incorporating molecular-level hazard analysis, exposure patterns, occupational exposure limits and conservative inhalation dose estimations was developed. Statistical agreement between both methods was examined using Cohen's κ, and McNemar's test assessed significant differences. Results. COSHH Essentials identified 76 hazardous substances, while the enhanced method identified 81 substances, including five additional requiring local exhaust ventilation. Agreement was moderate (κ = 0.58; p = 0.031). Conclusion. COSHH Essentials provides a useful baseline but lacks the specificity needed in industries with intentional close-range exposure. The enhanced method enables more precise, context-sensitive assessment and better protection in fragrance laboratories.
