Nursing Challenges in Pressure Injury Management: Global Prevalence Patterns and Projected Care Demands in Aging Populations

ABSTRACT

Aim

To assess the global burden of pressure injuries from 1990 to 2021 and project trends to 2050.

Design

A cross-sectional survey.

Methods

Using the Global Burden of Disease 2021 data from 204 countries (1990–2021), we performed a multilevel analysis incorporating age-period-cohort modelling, stochastic frontier analysis and Bayesian projections to 2050. Key metrics included age-standardised incidence rates, disability-adjusted life years and socio-demographic index stratification.

Results

Global incident cases increased by 160.3%, from 1.22 million to 3.18 million. By 2050, cases are expected to reach 8.4 million, with 72.4% in low-middle socio-demographic index areas. Mortality among those aged 95 and older may triple.

Conclusion

The study emphasises the need for global collaboration to address the burden of pressure injuries through equitable prevention and improved healthcare infrastructure, especially in ageing and resource-limited regions.

Implications for the Profession and/or Patient Care

The escalating global burden of pressure injuries in geriatric populations necessitates evidence-based approaches to optimise healthcare resource allocation and advance nursing-led prevention frameworks.

Reporting Method

The STROBE checklist guided reporting.

Patient or Public Contribution

Global Burden of Disease collaborators extracted the data and analysed it.

Evaluating the role of wound‐healing genes in conjunction with stool routine and serum tumor markers for colorectal cancer diagnosis and prognostic implications

Abstract

Colorectal cancer is a common malignant digestive tract tumour with high morbidity and mortality. Early detection, treatment and diagnosis are crucial for preventing and treating colorectal cancer, which develops through multi-stage accumulation and gene participation, affecting tumour marker levels. Chronic wounds can lead to the development of certain cancers, such as colorectal cancer. The prolonged inflammation and tissue repair caused by chronic wounds can trigger cellular changes, potentially promoting cancerous cell growth in the colon. The formation and progression of colorectal cancer involve changes in tumour markers, such as carcinoembryonic antigen (CEA), sugar chain antigen 19–9 (CA199) and CA125. This study explores the clinical application value of a stool routine combined with serum tumour marker detection in diagnosing colorectal cancer. The experiment team examined the clinical information of 56 colorectal cancer patients alongside a control group of 56 healthy patients. Distinct stool characteristics and heightened occult blood rates were evident in colorectal cancer cases. The combined approach integrating stool routine and serum tumour markers improved diagnostic accuracy, displaying enhanced sensitivity and specificity compared with individual markers or stool routines alone. Bioinformatics analysis indicated increased CEA and CA125 levels in colorectal cancer tissues versus normal tissues, hinting at potential prognostic implications. Exploring wound-healing genes like Vascular Endothelial Growth Factor A (VEGFA), Tumour Protein 53 (TP53) and Transforming Growth Factor Alpha (TGFA) revealed heightened expression in colorectal cancer, suggesting their potential role in disease progression. These markers showed associations with various immune cell types, suggesting their impact within the tumour microenvironment (p < 0.05). Single-cell RNA sequencing data highlighted varying CEA expressions across different cell populations in colorectal cancer. The findings indicated that integrating clinical assessments with accurate biomarkers may provide valuable insights into prognostic implications.
