Beyond carrying capacity: A system dynamics reinterpretation of Calhoun’s Universe 25 experiment and its relevance to managed animal populations

Calhoun’s Universe 25 experiment remains a significant and contested case study of population growth, crowding, social disruption and reproductive decline in a protected mouse population. Although commonly interpreted as evidence of physical overpopulation, its central implicatio...

Association Between the GMI / HbA1c Ratio and Microvascular Complications in Type 1 Diabetes: A Multicenter Cross‐Sectional Study

ABSTRACT Objective To clarify whether the glucose management indicator (GMI)/glycated haemoglobin (HbA1c) ratio (GMI/HbA1c ratio) is an independent predictor of microvascular complications in Type 1 diabetes (T1D). Design and Methods Multicentre, cross‐sectional, observational st...

Machines that express emotions: from medical paternalism to machine paternalism?

Abstract: Introduction: Machines do not have emotions, but they can be programmed to express (to appear to have) certain emotions. In medicine, robots and AI machines are used that could express positive emotions (joy, compassion, hope, gratitude, inspiration or awe) and prioriti...

HIV-1 Drug Resistance in Mother–Infant Pairs in Southern Mozambique

This prospective nested cohort (EARTH) study evaluated drug resistance mutations and outcomes among 79 (31 with genetic results) early-treated Mozambican children living with HIV, followed for 50 months. Mortality reached 20.3%. Drug resistance mutations were detected in 58.1% of...

What are the knowledge, use, and perceived benefits and limitations of artificial intelligence chatbots among Italian nursing students? A cross-sectional multicentre study

Exploring students’ knowledge, use, and perceptions of Artificial Intelligence (AI) chatbots may inform strategies in the educational context. However, limited evidence is available on Italian nursing students, leaving this field largely unexplored. A cross-sectional online surve...

Clinical Complications of Fixed Anterior Prostheses After Traumatic Premature Loss of Primary Maxillary Incisors: A Retrospective Cohort Study

BACKGROUND/AIM: Premature loss of primary maxillary incisors after traumatic dental injuries may require secondary rehabilitation in preschool children. Evidence on complications associated with fixed anterior prostheses in this context remains limited. This retrospective cohort...

Dental trauma management knowledge among primary healthcare professionals in the Valencian Community, Spain: a cross-sectional study

Dental trauma represents one of the main dental emergencies, with a significant prevalence in both pediatric and adult populations. Primary healthcare settings constitute the first point of contact for patients experiencing dental trauma. This study aimed to assess the level of k...

Baseline Ferritin and Body Composition as Correlates of Longitudinal Metabolic Changes During an Energy-Restricted Mediterranean-Style Intervention Across Three Overweight Phlogistic-Related Clinical Conditions

Background/Objectives: Chronic inflammation accompanies obesity, but correlations of longitudinal changes during dietary follow-up remain unclear. We described inflammatory profiles and examined associations of baseline ferritin and body composition with changes during a 32-week...

Sense of Community, Intergenerational Interaction and Skill Development in Heritage Education: Evidence from Flamenco in Spain

Research on intangible cultural heritage in educational contexts has largely focused on symbolic, identity-related, and curricular values, paying limited attention to the social mechanisms that sustain its transmission as living heritage. In particular, empirical evidence on how...

Comparative aerodynamic performance assessment of NACA 2412 and NACA 0012 aerofoils with winglet integration: a computational study using MATLAB-CATIA-CFD framework

Winglets are aerodynamic devices that reduce induced drag by mitigating wingtip vortices, thereby improving aircraft fuel efficiency and overall performance. This study presents a comparative computational investigation of the aerodynamic performance of wings with NACA 2412 (camb...

Combinations of stepping intensity and daily step counts against all-cause and cardiovascular disease mortality: insights from a device-based prospective study

Objective Understanding the joint role of stepping intensity and step counts could inform pragmatic step-based physical activity strategies for premature mortality prevention. We examined the joint association of stepping intensity and daily step counts with all-cause mortality (...

Effects of a virtual reality training program on perceptual-motor performance and autonomic modulation in soccer goalkeepers

Immersive virtual reality (VR) may provide a controlled environment for perceptual-motor practice in soccer goalkeepers, although evidence for transfer and psychophysiological adaptation remains limited. This non-randomized controlled study examined 32 male youth goalkeepers: 20...

Implementing shared decision making in the everyday work of clinicians providing cardiovascular preventive care: evaluating the implementation of an electronic encounter tool in three U.S. healthcare systems

Shared decision making (SDM) is guideline-recommended for primary prevention of cardiovascular (CV) disease, but there are barriers to routine adoption of tools to promote SDM. This pragmatic trial evaluated the effect of tailored strategies on implementation of an SDM tool ( CV...

Clinical outcomes of stereotactic body radiotherapy in oligometastatic disease: a national real-world cohort study

Abstract Purpose We conducted the first multicentre Spanish real-world study assessing the efficacy and safety of stereotactic body radiotherapy (SBRT) in oligometastatic patients treated in routine clinical practice. Methods This retrospective, multicentre observational study in...

Effects of Physical Activity Interventions on Cognitive Flexibility in Children with ADHD: A Systematic Review

Background: Attention Deficit Hyperactivity Disorder (ADHD) is associated with impairments in executive functions, particularly cognitive flexibility, which may negatively affect academic performance, behavioral regulation, and daily adaptation in children. Physical activity has...

Long-term effects of cognitive-behavioral therapy for adults with ADHD: results from an 8-year randomized controlled trial follow-up

Abstract Background To evaluate the provisional long-term durability of group cognitive behavioral therapy (CBT) benefits 8 years post-baseline and to explore tentative associations between digital booster engagement and the maintenance of treatment gains in adults with ADHD. Met...

Placebo and nocebo effects on pain through the lens of the predictive brain: Neurobiological mechanisms and translational implications

Placebo and nocebo effects on pain provide a model for investigating how cognitive and contextual factors modulate the physiological processes underlying nociception and its regulation. However, existing accounts remain fragmented and lack a unifying mechanistic framework linking...

Geopolitical Risks and Fossil Fuel Returns during the Last Four Decades

Abstract This paper empirically investigates the directional predictability of geopolitical risks (distinguishing between geopolitical acts and threats) on the returns of fossil fuels (crude oil, coal, and natural gas) over the last four decades, from January 1984 to February 202...
