Analysis of Mental Health and Accelerated Use of Technologies: A Psychological Study among Chilean Workers

2026-07-09T23:24:58+00:00

Technostress is an emerging psychosocial risk associated with the accelerated adoption of technologies in the workplace. Although its impact on mental health has been documented in the educational sector, there is limited evidence in Chile regarding other occupational sectors. This study examined the relationship between technostress and mental health, specifically anxiety, depression, and stress, in 178 Chilean workers, using a cross-sectional correlational-predictive design. The Technostress Creators Scale, RED-TIC, and DASS-21 were administered, and mean comparisons, correlations, network analysis, and multiple regressions were performed. Sociodemographic differences were limited, with higher techno-insecurity observed in men and higher techno-intrusion among young workers and fee-based workers. Technostress manifestations showed moderate associations with mental health, exceeding those observed for technostress creators. Techno-intrusion predicted distress, while technological skepticism predicted depression. The findings suggest the need to incorporate technostress as a psychosocial risk and to further explore the mediation mechanisms among the variables.

Concentrate of Omega-3 Fatty Acids EPA and DHA Obtained by Winterization of Crude Anchovy Oil (Engraulis ringen)

2026-07-11T03:24:25+00:00

This study evaluated the production of a concentrate of omega-3 fatty acids EPA and DHA through the winterization of crude anchovy oil (Engraulis ringens). Two samples obtained from processing plants in Chimbote and Callao, Peru, were subjected to temperatures of 22, 10, 5, 0, and −5 °C for 96 h. Free acidity and iodine value were determined according to Peruvian technical standards, while the fatty acid profile was analyzed by gas chromatography. The samples treated at 0 and −5 °C crystallized completely and were therefore excluded from further analysis. The treatment at 5 °C produced the highest enrichment of EPA and DHA, reaching combined contents of 39.99% and 40.19% in the Chimbote and Callao samples, respectively. In addition, free acidity remained within regulatory limits, and the iodine value increased, confirming that winterization is an efficient alternative for concentrating omega-3 fatty acids while preserving oil quality.

Optimization of Temporary Shelter Locations Using Spatial Accessibility Analysis for Earthquake Response

2026-07-13T16:06:48+00:00

Earthquakes represent a significant threat to urban areas, where territorial vulnerability increases the risk to the population. The objective of this study was to optimize the location of temporary shelters through a spatial accessibility analysis to strengthen earthquake response. A quantitative, applied, non-experimental study was conducted using Geographic Information Systems (GIS), the Analytic Hierarchy Process (AHP), and multicriteria analysis. The model integrated variables related to seismic hazard, topography, geology, soil type, road accessibility, and population distribution to identify optimal shelter locations and evacuation routes. The results showed a predominance of areas with high and very high hazard levels, allowing the proposal of thirteen strategically distributed shelters. It is concluded that the integration of GIS and AHP constitutes an effective tool to support territorial planning and strengthen seismic risk management.

Structural Diversity and Chemical Space of Flavonoids Reported in Latin American Plant Resources: A Cheminformatics Study

2026-07-14T16:28:53+00:00

Flavonoids constitute a group of plant metabolites of high interest due to their structural diversity and the influence that their chemical modifications exert on their molecular properties. This study characterized the structural diversity and chemical space of flavonoids reported in Latin American plant resources through the integration and curation of open data from COCONUT and PubChem. The methodology was based on the construction of a regional corpus, its strict curation according to chemical consistency and biological origin, nominal integration with PubChem, and descriptive and multivariate analysis of physicochemical descriptors. The results showed a structurally heterogeneous set, with a predominance of methoxylated and glycosylated flavonoids, high chemical traceability between databases, and a discernible organization of the chemical space. Overall, this study provides a reproducible pathway for exploring Latin American natural metabolites using cheminformatics tools

Professional Competencies in Nursing Students: A Systematic Review

2026-07-21T00:32:40+00:00

The development of professional competencies is an essential component in the education of nursing students due to the growing demands of health systems. The objective of this systematic review was to synthesize the scientific evidence on professional competencies, the educational strategies used for their development, and the factors that favor or limit their consolidation. The review was conducted according to the PRISMA 2020 guidelines through searches in international databases and the application of previously established eligibility criteria. The studies analyzed show that clinical simulation, supervised practice, continuous feedback, and reflective learning strengthen clinical, communicative, ethical, and critical reasoning competencies. In addition, the quality of the clinical environment, teacher mentoring, and professional identity significantly influence competency development. It is concluded that competency-based education requires comprehensive pedagogical strategies and educational contexts that promote meaningful learning.

Credibility of Journalistic Information Disseminated on Digital Migrant Media Fanpages: Perception of Union Members

2026-07-28T00:34:46+00:00

The consolidation of digital migrant media has transformed the production and consumption of journalistic information, posing new challenges for credibility in digital environments. The objective of this study was to determine the relationship between journalistic information disseminated on fanpages of digital migrant media and the credibility perceived by union members. A quantitative, non-experimental, cross-sectional, and correlational study was conducted with 109 participants from the Workers’ Union of the National University of Santa. The information was obtained through a questionnaire validated by experts and with adequate reliability (α = 0.866). The results showed a high positive correlation between both variables (ρ = 0.722; p < 0.001), highlighting live streaming as the dimension with the strongest association with credibility. It is concluded that the quality of journalistic content constitutes an essential factor for strengthening trust in digital media.

Pharmaceutical Product Management Model in Healthcare Facilities: A Systematic Review

2026-07-24T04:02:24+00:00

Pharmaceutical product management is essential to the quality of healthcare, as it directly influences patient safety and therapeutic outcomes. This study presents a systematic review of pharmaceutical management models in healthcare facilities, examining their impact on medication availability, treatment adherence, and process efficiency. A total of 25 studies published between 2021 and 2025 in international databases were reviewed. The findings show that the most effective models integrate digital systems, continuous staff training, and quality standards, promoting the rational use of medicines and improved healthcare services.

Quality Problems in Family Medicine Services in Latin American Hospitals: A Systematic Review

2026-07-24T22:01:57+00:00

The research aimed to analyze quality-related problems in family medicine services in hospitals across Latin America. A systematic literature review was conducted following the PRISMA 2020 guidelines, with searches in indexed databases (Scopus, Web of Science, PubMed, and SciELO), resulting in the selection of 21 studies published between 2020 and 2024.
