To assess the association between educational level and cardiovascular age acceleration metric derived from ECG, and to determine whether this association is mediated by established cardiovascular disease (CVD) risk factors.

Prospective population-based cohort study (the Tromsø Study).

General population of the Tromsø municipality, Norway.

The study sample consisted of 4367 participants of the Tromsø Study, who took part in both Tromsø6 (2007–2008) and Tromsø7 (2015–2016), had a 12-lead ECG obtained at Tromsø7 and did not report a history of heart attack, stroke or atrial fibrillation.

-age, a biomarker of cardiovascular ageing, is defined as the difference (in years) between an individual’s ECG-predicted heart age and their chronological age. ECG-predicted heart age was estimated using a previously validated deep neural network.

Our findings indicate an inverse association between education and -age, with a regression coefficient per increment increase in education of –0.24 (95% CI –0.41 to –0.07) in the overall sample, –0.38 (95% CI –0.59 to –0.16) for women and –0.04 (95% CI –0.31 to 0.23) for men. Participants with the highest level of education (university/college for 4 or more years) had the lowest estimated -age with a regression coefficient of –0.69 years (95% CI –1.23 to –0.16) compared with the group with primary education for the overall sample, –1.05 years (95% CI –1.73 to –0.37) for women and –0.15 years (95% CI –1.03 to 0.73) for men. CVD risk factors mediated up to 75% of the association between overall education and -age, and 80% of the association among those with the highest education level (university/college for 4 or more years). Among women, 50% of the effect of overall education on -age was mediated by CVD risk factors, rising to 53% in the category with the highest level of education. However, in the subsample of men, there was no significant association between education and -age, and the mediation analysis produced natural direct and indirect effects pointing in opposite directions.

Cardiovascular ageing is inversely associated with educational level, an effect that appears to be largely mediated through established risk factors.

Few studies have investigated the prevalence of chronic wounds and the clinical and sociodemographic characteristics of hospitalised patients affected by them. Understanding these characteristics within the inpatient setting can support improved follow-up, inform care strategies, enhance quality and safety and reduce associated healthcare costs. This study aimed to determine the prevalence and the sociodemographic profile of adult inpatients with chronic wounds admitted to the eight hospitals of the Catalan Institute of Health between 2016 and 2020.

A descriptive, observational, cross-sectional and retrospective multicentre study was conducted using routinely collected clinical data from 1 January 2016 to 31 December 2020. The study encompassed hospital wards, step-down units and home hospitalisation services across eight public hospitals managed by the Catalan Institute of Health, the main public healthcare provider in Catalonia, Spain. The study included all patients aged 18 years or older who were hospitalised with chronic wounds during the study period. The main variables were nursing diagnoses of chronic wound types: pressure injuries (PIs), arterial ulcers (AUs), venous ulcers (VUs), mixed ulcers and diabetic foot ulcers (DFUs), as recorded in nursing electronic health records. Secondary variables included age, sex, reason for admission, unit of admission, hospital type, source of admission and discharge destination. A descriptive and comparative analysis was performed.

Among 796 698 hospitalised patients, 16 935 (2.1%) presented with at least one chronic wound. The most common types of chronic wounds were PIs and AUs. A slight decline in the prevalence of chronic wounds was observed over the study period. Cardiovascular and respiratory conditions were the leading causes of admission among these patients. AUs and DFUs were more prevalent in men, whereas VUs were more frequently observed in women. Patients with PIs had longer hospital stays, higher rates of intensive care unit admissions and increased in-hospital mortality. In contrast, patients with vascular ulcers more often required continued care after discharge (p

Chronic wounds continue to represent a significant healthcare challenge. It is essential to consider the clinical characteristics and health outcomes of hospitalised patients with chronic wounds in order to improve care quality and safety. Further research is warranted to explore the relationship between patient care complexity and the type of chronic wounds present.
