Sex, Perceived Social Support, and Physical Activity as Correlates of Depressive Symptoms in Informal Caregivers: A Cross-Sectional Analysis of the Spanish National Health Survey 2023

Background/Objectives: Informal caregivers are at an increased risk of developing depressive symptoms; however, the combined role of sex, perceived social support (PSS), and physical activity (PA) in this population remains insufficiently characterized. This study aimed to descri...

Geotechnical Problems on Madeira Island: Slope Protection in Central Funchal—A Case Study

Volcanic islands are highly exposed to interacting geotechnical and hydrogeomorphological hazards, particularly where steep relief, intense rainfall, fractured volcanic rocks, and urban development coincide. This study analyzes the slope located along Avenida Sá Carneiro in centr...

Closed‐form solutions for dynamic punching shear assessment in flat slabs subjected to sudden column removal

Abstract Simplified closed‐form equations are commonly used in structural design to prevent punching shear failures of concrete flat slabs supported on columns in permanent and transient situations, whereas more advanced methods are generally used in verifications at accidental d...

Scale or market composition? Short-term rentals and residential rents in Spain

Purpose This study aims to examine whether short-term rental (STR) pressure is associated with residential rent growth uniformly across Spanish housing markets or whether the relationship depends on market composition and spatial scale. Design/methodology/approach The author comb...

Teachers’ Perceptions of Generative Artificial Intelligence in Early Childhood and Primary Education: Barriers, Ethical Concerns, and Perceived Impacts

The growing integration of Generative Artificial Intelligence (GAI) into education has intensified the need to understand teachers’ perceptions of its implementation in the early stages of schooling. This study aimed to examine the barriers, ethical concerns, and perceived impact...

A stochastic approach to optimising façade maintenance in healthcare buildings

Purpose Developing effective maintenance strategies is a major challenge for healthcare facility managers to ensure the ongoing operation of buildings. The aim of this research was to model the degradation of the façades of Healthcare Buildings, determining the best maintenance d...

Valorization of Hordeum vulgare Residues into Activated Carbon for Paracetamol Removal from Water

The presence of pharmaceutical compounds in aquatic systems represents a growing concern due to their persistence and potential adverse effects on ecosystems and human health. In this study, activated carbon obtained from Hordeum vulgare residues was developed and evaluated for t...

Metabolic Age as a Potential Marker of Cardiometabolic Vulnerability in Institutionalised Older Adults: A Cross-Sectional Study

Background/Objectives: Chronological age is a major determinant of cardiovascular risk and metabolic syndrome, but it may not accurately reflect biological ageing or cardiometabolic vulnerability. Metabolic age has emerged as a potential indicator of metabolic health, although it...

Is Coaches’ Perceived Team Performance Associated with Training Load and Fatigue in Spanish Semi-Professional Soccer?

Objectives: This study investigated the influence of coaches’ perceived team performance on training load and fatigue across the weekly microcycle in semi-professional soccer players. Methods: Twenty-four players were monitored over 183 training sessions during a 34-week competit...

Hydroalcoholic extraction and carbon-coated zero-valent iron nanoparticles: Comparative valorisation routes for olive mill wastewater

This study evaluated two valorisation routes for olive mill wastewater (OMW): hydroalcoholic extraction of a crude phenolic-rich fraction and hydrothermal carbonisation (HTC) to produce carbon-coated zero-valent iron nanoparticles (FeC 0 NPs). Their cradle-to-gate profiles were c...

Psychometric validation of the teachers’ responses to bullying questionnaire (TRBQ) among Spanish adolescents

Abstract Background Adolescents’ perceptions of teachers’ responses to bullying are relevant to understanding how adult intervention is experienced in school settings. Although the Teachers’ Responses to Bullying Questionnaire (TRBQ) has been validated in several countries, previ...

Longitudinal and reciprocal relationships between physical activity, physical fitness, executive functions, and arithmetic fluency in adolescents

Abstract Background The relationship between physical health and academic outcomes in adolescents is well-established, but the directionality and reciprocal nature of these associations remain unclear. Given the foundational role of mathematical skills in academic success, this s...

Spatial Variability and Magnitude of Soil Erosion in Vineyards Across Spain: Insights from Standardized ISUM Measurements

Soil erosion and sediment redistribution in vineyards often exceed tolerable thresholds, but comparative field measurements across regions remain limited because studies use different methods and sampling designs. This study assesses soil redistribution in vineyards using a commo...

Zileuton protects pancreatic stellate cells from oxidative stress and ferroptosis by modulating the Nrf2 pathway and mitochondrial activity

Abstract Lipoxygenases exhibit a leading role in cancer development and growth. Additionally, pancreatic stellate cells (PSCs) are pivotal in the formation of fibrotic tissue in pancreatic tumors. In this work, we have studied the effects of the 5-lipoxygenase (5-LOX) inhibitor,...

Effects of a multicomponent exercise programme including high-intensity interval training in institutionalised older adults with probable sarcopenia: a multicentre randomised controlled trial

Exercise is one of the most promising non-pharmacological interventions for maintaining or improving physical function in older age. Although high-intensity interval training (HIIT) is feasible and safe in older adults with frailty, its effects on institutionalised older adults w...

Association of Native American, European, and African Ancestry with CYP450 Pharmacogenetics and Metabolic Phenotypes in Admixed Latin American Populations from Ecuador and Nicaragua

Background/Objectives: Interethnic variability significantly influences drug response, highlighting the importance of assessing genomic ancestry for personalized medicine. Although Latin American populations are highly admixed, they remain underrepresented in pharmacogenetic rese...

Pharmacogenetic, Clinical, Prescribing, and Demographic Predictors of Sertraline Pharmacokinetics

Background: Interindividual variability in sertraline pharmacokinetics remains substantial, but the relative contributions of pharmacogenetic (PGx), demographic, clinical, and prescribing determinants have not been comprehensively evaluated in routine clinical practice. The study...

Consumer‐Orientation Effects in Sustainable Beer Valuation

ABSTRACT This paper examines whether consumers' valuation of a product‐level sustainability claim differs according to their beer‐consumption orientation. Using a discrete choice experiment with 1046 Spanish beer consumers, we estimate conditional logit and panel mixed logit mode...

Lifestyle and its relationship with health literacy, sense of coherence and sociodemographic factors in a Spanish primary care population: a multicenter cross-sectional study

Health behaviors are driven by a complex interplay of individual and structural factors. While health literacy and sense of coherence are widely studied as psychosocial enablers of healthy lifestyles, evidence comparing their impact against broader social determinants of health r...

Genetic Basis of Tobacco Use Disorder

Tobacco use disorder (TUD) is a complex multifactorial condition resulting from the interplay between nicotine-induced neurobiological adaptations, behavioral and learning processes, environmental influences, and individual genetic susceptibility. Genetic research has progressive...
