Cox regression analyses revealed that male sex (hazard ratio [HR] 1.32, 95% confidence interval [CI]: 1.25-1.39), advanced age (HR 8.54, 95% CI: 7.40-9.87 for ≥95 years vs. 65-69 years) and comorbidities such as neurological disorders (HR 1.87, 95% CI: 1.72-2.04), dementia (HR 1.69, 95% CI: 1.59-1.80), and congestive heart failure (HR 1.19, 95% CI: 1.12-1.27) were associated with increased PI risks. Conversely, antihyperlipidemic drugs may be associated with a lower PI risk (HR 0.69, 95% CI: 0.65-0.74). Due to data limitations, factors such as nutritional status, mobility, and caregiver support could not be evaluated. <b>Innovation:</b> This study is the first in Japan to leverage big data to identify high-risk groups for PIs, particularly among elderly individuals with specific comorbidities. This approach offers actionable insights into PI management, potentially enhancing care strategies and preventive guidelines. <b>Conclusion:</b> Male sex, advanced age, and comorbidities, including neurological disorders, dementia, psychosis, and congestive heart failure, were identified as primary PI risk factors. Conversely, antihyperlipidemic drug use may be associated with a lower PI risk.

In clinical scenarios with a segmental nerve gap where end-to-end coaptation without tension is not possible, a \"bridge\" or scaffold must be interposed to facilitate communication between the proximal and distal stumps to facilitate organized growth following Wallerian degeneration. A multitude of constructs have been created and studied to facilitate this regeneration. Among the three overall types of bridge employed in contemporary clinical care-conduit/scaffold, allograft, and autograft-each has significant downsides ranging from limited successful nerve ingrowth to donor site morbidity.

Ongoing studies have identified several promising modalities for nerve scaffolds to facilitate more efficient and effective neuronal outgrowth but still require further investigation.

Injuries can cause a dysregulated environment, resulting in chronic inflammation and inhibition of cell proliferation and migration, which delays recovery. Innovative approaches, such as three-dimensional (3D) bioprinting, can foster a controlled healing environment by promoting synergy between the skin microbiome and cells. <b>Recent Advances:</b> Traditional approaches to wound healing have focused on fostering an environment conducive to the interplay between cells, extracellular proteins, and growth factors. 3D bioprinting, a manufacturing technology with applications in tissue engineering, deposits biomaterial-based bioink containing living cells to fabricate custom-designed tissue scaffolds in a layer-by-layer fashion. This process controls the architecture and composition of a construct, producing multilayered and complex structures such as skin. <b>Critical Issues:</b> The selection of biomaterials for scaffolds has been a challenge when 3D skin tissue engineering. While prioritizing mechanical properties, current biomaterials often lack the ability to interact with environmental stimuli such as pH, temperature, or oxygen levels. Employing smart biomaterials that integrate bioactive molecules and adapt to external conditions could overcome these limitations. This innovation would enable scaffolds to create a sustainable wound-healing environment, fostering microbiome balance, reducing inflammation, and facilitating cellular recovery and tissue restoration, addressing critical gaps in existing wound care solutions. <b>Future Directions:</b> Novel bioink formulations for skin injury recovery are focused on improving long-term cell viability, proliferation, vascularization, and immune integration.
