Article Abstract
This study explicates mechanisms of media campaign effectiveness in the context of children's physical activity. The authors' model expands the theory of planned behavior by integrating injunctive and descriptive norms into its normative mechanism. Analysis of a 3-wave nationally representative evaluation survey among 1,623 tweens indicates that campaign exposure is significantly related, but only indirectly, to both physical activity intention and physical activity behavior. Instead, campaign exposure seems more strongly related to perceived behavioral control and attitudes toward physical activity. By contrast, perceived behavioral control and descriptive norms are strongly related to behavioral intention. The findings suggest that integrating normative mechanisms with the theory of planned behavior can improve efforts to predict and explain a health behavior.

The emerging role of Nrf2 in heart failure: From cardioprotection to therapeutic approaches.
ESC Heart Fail
September 2025
Department of Clinical and Molecular Medicine, Sapienza University, Rome, Italy.
Heart failure (HF) is a multifactorial and pathophysiological complex syndrome, involving not only neurohormonal activation but also oxidative stress, chronic low-grade inflammation, and metabolic derangements. Central to the cellular defence against oxidative damage is nuclear factor erythroid 2-related factor 2 (Nrf2), a transcription factor that orchestrates antioxidant and cytoprotective responses. Preclinical in vitro and in vivo studies reveal that Nrf2 signalling is consistently impaired in HF, contributing to the progression of myocardial dysfunction.

Background: Poor hand dexterity may increase the risk of functional disability; however, few studies have examined the relationship between hand dexterity and incident functional disability. The aim of this study was to prospectively investigate the dose-response association of hand dexterity with incident functional disability in community-dwelling older adults.
Methods: This study included 1,069 older adults aged ≥65 years in Kasama City, Japan.
Is high specific surface area essential for anode catalyst supports in proton exchange membrane water electrolysis?

Dispersing iridium onto high-specific-surface-area supports is a widely adopted strategy to maximize iridium utilization in anode catalysts of proton exchange membrane water electrolysis (PEMWE). However, here we demonstrate that the overall cell performance, including initial efficiency and long-term stability, does not benefit from the typical high specific surface area of catalyst supports. The conventional understanding that high iridium utilization on high-specific-surface-area supports increases activity holds only in aqueous electrolytes, while under the typical working conditions of PEMWE, the mass transport within the anode catalyst layers plays a more significant role in the overall performance.

Background: The Scale for the Assessment and Rating of Ataxia (SARA) is the most used outcome measure in clinical trials for cerebellar ataxias. The minimal clinically important difference (MCID), a parameter used to assess meaningful change, is not clearly defined.
Objective: To help define MCID for SARA.

Multimorbidity of chronic diseases is one of the most common health issues among older adults, and the resulting demand for long-term medical care and management imposes a considerable burden on healthcare systems. Muscle strength, a core indicator of overall health status, is closely associated with the risk of developing multimorbidity of chronic diseases in older adults. Decline in muscle strength not only increases the risk of multimorbidity of chronic diseases but also interacts with it to exacerbate disease burden.
