Article Abstract
Background: With aging, a decline in intrinsic capacity can lead to functional impairments, thereby increasing the risk of adverse health outcomes.
Objectives: This study aims to explore the prediction of intrinsic capacity decline on adverse health outcomes, such as falls and disability, over the course of 1 year. By addressing the gap in longitudinal research on community populations in China, the study seeks to deepen the local understanding of healthy aging theory, providing theoretical support for the development of elderly health intervention strategies tailored to Chinese contexts.
Methods: A convenience sampling method was employed to select 248 community-dwelling elderly participants. Over a 1-year follow-up period, the outcomes of falls and disability were monitored. Logistic regression analysis was used to evaluate the relationship between intrinsic capacity and these outcomes.
Results: Among the 248 participants, 46 (19%) experienced falls, and 31 (12.8%) became disabled during the follow-up year. The locomotive dimension (OR = 25.87, 95% CI: 2.95-227.03), psychological dimension (OR = 25.29, 95% CI: 6.45-99.28), and sensory dimensions (OR = 10.75, 95% CI: 2.92-39.56) were identified as significant risk factors for falls. For disability, the locomotive dimension (OR = 4.15, 95% CI: 0.97-17.72), cognitive dimension (OR = 11.27, 95% CI: 3.51-36.18), and psychological dimension (OR = 4.58, 95% CI: 1.69-12.40) were significant risk factors.
Conclusion: Decline in intrinsic capacity serves as an independent predictor of both falls and disability among community-dwelling elderly individuals over the course of 1 year. Early identification of elderly individuals with decreased intrinsic capacity, along with targeted interventions based on different intrinsic capacity levels, can effectively reduce the incidence of falls and disability.

Ferric derisomaltose augments intrinsic skeletal muscle electron transport chain activity in heart failure: A FERRIC-HF II molecular substudy.

Aims: Skeletal muscle energetic augmentation might be a mechanism via which intravenous iron improves symptoms in heart failure, but no direct measurement of intrinsic mitochondrial function has been performed to support this notion. This molecular substudy of the FERRIC-HF II trial tested the hypothesis that ferric derisomaltose (FDI) would improve electron transport chain activity, given its high dependence on iron-sulfur clusters which facilitate electron transfer during oxidative phosphorylation.
Methods And Results: Vastus lateralis skeletal muscle biopsies were taken before and 2 weeks after randomization.

Background: Ageing in place has been promoted in the Netherlands to encourage optimal functional ability (FA) and independent living among older adults. FA is likely dependent on intrinsic capacity (IC), a composite measure of an individual's mental and physical capacities-and its interaction with the physical environment in which people live. This study aimed to examine the association between IC and FA, as well as to explore how the physical environment may modify this relationship in older adults.

The exponential growth of data in the information era has pushed conventional optical communication technology to its limitations, including inefficient spectral utilization, slow data rate, and inherent security vulnerabilities. Here, a transformative high-speed organic spectral wireless communication (SWC) technology enabled by a flexible, miniaturized, and high-performance organic hyperspectrometer is proposed that integrates ultrahigh-speed data transmission with hardware-level encryption. By synergistically combining organic photodetector arrays with tunable responsivities and spectral-tunable organic filters, the organic hyperspectrometer achieves a broad spectral detection range of 400 to 900 nm, resolution of 1.

Ammonium (NH) toxicity significantly limits nitrogen use efficiency (NUE) in agriculture. Nitrate (NO) supplementation mitigates this toxicity, with the anion channel SLAH3 playing a central role by mediating NO efflux to counteract NH-induced rhizosphere acidification. SLAH3, a plasma membrane protein with ten transmembrane domains and cytosolic N- and C-termini, is intrinsically silent.

Aramid films are potential separator candidates for high-safety lithium-ion batteries (LIBs) due to their inherent flame retardancy and outstanding thermal stability. However, both weak liquid electrolyte wettability and poor mechanical properties of aramid separators for lithium-ion batteries result in low ionic conductivity and unsatisfactory electrochemical performance for LIBs. Herein, a novel asymmetric porous composite separator composed of a relatively dense nanocellulose (CNC) layer and a porous poly(m-phenylene isophthalamide) (PMIA) supporting layer has been fabricated by using a water-induced phase conversion process.
