Systematic scoping review. Pressure injuries (PI) are a serious but mostly preventable complication associated with living with spinal cord injuries (SCI). This review aims to identify and summarize evidence concerning self-managed digital technologies for preventing PI in the SCI population. A systematic search was performed across seven databases—Embase, Medline, PsycInfo, Web of Science, Scopus, CENTRAL, and CINAHL. To be eligible, studies had to be peer-reviewed and report original findings on self-managed digital technologies for PI prevention in adults (≥18 years) with SCI. Supplementary searches were conducted using Google Scholar, PEDro, and citation tracking to locate relevant studies not identified by the systematic search. Data from the included studies were extracted and synthesized. The systematic search identified 9797 unique studies. After screening and excluding 8939 records at the title-and-abstract level, 858 full-text records were assessed, and 12 met the inclusion criteria. The included studies fell into categories: (i) technology-driven feedback systems that provide real-time pressure distribution data and (ii) digital self-management and educational systems aimed at improving adherence to PI-preventive measures. Feedback systems were associated with improved pressure-relieving behaviours, though adherence to reminder-based interventions remained a challenge. Digital self-management tools were shown to enhance knowledge and confidence related to PI prevention. Self-managed digital technologies increased awareness, confidence, and engagement in pressure relief behaviours among individuals with SCI. However, their direct impact on PI prevention remains inconclusive. Difficulties relating to adherence indicate that such technologies should complement, rather than replace, traditional prevention strategies.

The 4% Rule Revisited: A New Take On A Retirement Classic

Scoping review. Spasticity is a common and often challenging sequela of spinal cord injury (SCI) associated with pain, contractures, and reduced quality of life. While passive movement (PM) is primarily used to maintain joint mobility, clinical observations and participant reports suggest that both manual and automated techniques can contribute to the management of spasticity in SCI. However, the evidence base concerning PM’s impact on spasticity outcomes in SCI populations remains unclear. This review aims to identify the scope and synthesize the empirical evidence of PM interventions for managing spasticity in individuals with SCI. Seven databases (Embase, Medline, PsycInfo, Web of Science, Scopus, CENTRAL, and CINAHL) were systematically searched. Eligible studies were peer-reviewed, reported original data, included adult participants (≥18 years) with SCI, presented a therapeutic intervention consisting solely of PM techniques, and reported any spasticity outcome. Data were extracted and analyzed by two independent reviewers. The initial search identified 1628 unique studies, of which 13 were included for analysis. The PM interventions included passive cycling and robotic PM interventions (n = 8), continuous passive motion (n = 4), and manual passive range of motion (PROM) (n = 1). While a minority of studies demonstrated sustained improvements in spasticity outcomes, the majority reported short-term reductions observed in small sample groups, single-session experiments, or using suboptimal research designs. This review assembled the existing evidence on PM interventions for managing spasticity in individuals with SCI. Despite finding consistent short-term improvements, further high-quality research is needed to determine clinical efficacy and inform future rehabilitation practices.

Marine biological invasions are accelerating under the influence of global trade and climate change, posing one of the most pressing threats to ocean biodiversity. This review critically examines the genetic consequences of invasive species in marine ecosystems, with a focus on mechanisms such as hybridization, introgression, genetic homogenization, and population bottlenecks. Invasive species not only disrupt native gene pools through processes such as hybridization and genetic introgression but can also shift evolutionary pathways, reduce adaptive potential, and destabilize ecological networks.
