- PURPOSE: The aim of this study was to investigate the prevalence and severity of incontinence-associated dermatitis (IAD) and associated factors in acute care settings in Southeast Norway.DESIGN: Descriptive, multisite epidemiologic survey.SUBJECTS AND SETTING: The study setting was 29 wards across 4 hospitals, in a hospital trust in the southeast of Norway. Data were collected from 340 patients (age ≥18 years). More than half (56.2%) were 70 years or older (median age category 70-79 years) and 53.3% were male.METHODS: Data collection was conducted in parallel with a pressure injury prevalence study undertaken in 2016. A modified Pressure Injury Prevalence Minimum Data Set, including documentation of fecal or urinary incontinence, use of indwelling fecal collection system or urinary catheter, and presence of IAD, was completed. RNs participating in the study were trained by the researchers on skin assessment and data extraction from the electronic medical record. Descriptive statistics were used for prevalence figures; the Kruskal-Wallis and χ tests were used to determine associated factors.RESULTS: Analysis revealed that 16.5% (56 out of 340) of the sample were incontinent. The prevalence of IAD in the total population was 7.6% (26 out of 340). The prevalence of IAD was 29% (16 out of 56) among patients with urinary or fecal incontinence. Of those identified with IAD, 5.2% (18 out of 340) had category 1 (red intact skin) and 2.4% (8 of 340) had category 2 (red skin with breakdown). Bivariate analysis revealed that fecal incontinence (P < .001), immobility (P < .01), and 70 years or older (P < .03) were associated with IAD.CONCLUSIONS: The overall prevalence (patients with and without incontinence) of IAD was lower than reported in prior studies; frequent use of indwelling urinary catheters and a relatively low prevalence of incontinence may explain this finding. Similar to prior studies, almost 1 in 3 patients who were incontinent suffered from IAD, showing a need for evidence-based guidelines to prevent IAD in hospitalized patients. Findings suggest that particular attention should be given to prevent IAD among patients with fecal incontinence patients, 70 years and older, and those with immobility.

- Stromal stiffening accompanies malignancy, compromises treatment and promotes tumour aggression. Clarifying the molecular nature and the factors that regulate stromal stiffening in tumours should identify biomarkers to stratify patients for therapy and interventions to improve outcome. We profiled lysyl hydroxylase-mediated and lysyl oxidase-mediated collagen crosslinks and quantified the greatest abundance of total and complex collagen crosslinks in aggressive human breast cancer subtypes with the stiffest stroma. These tissues harbour the highest number of tumour-associated macrophages, whose therapeutic ablation in experimental models reduced metastasis, and decreased collagen crosslinks and stromal stiffening. Epithelial-targeted expression of the crosslinking enzyme, lysyl oxidase, had no impact on collagen crosslinking in PyMT mammary tumours, whereas stromal cell targeting did. Stromal cells in microdissected human tumours expressed the highest level of collagen crosslinking enzymes. Immunohistochemical analysis of biopsies from a cohort of patients with breast cancer revealed that stromal expression of lysyl hydroxylase 2, an enzyme that induces hydroxylysine aldehyde-derived collagen crosslinks and stromal stiffening, correlated significantly with disease specific mortality. The findings link tissue inflammation, stromal cell-mediated collagen crosslinking and stiffening to tumour aggression and identify lysyl hydroxylase 2 as a stromal biomarker.
