Evaluation of the impact of atherosclerotic cardiovascular disease (ASCVD), particularly polyvascular disease, on 30-day and 365-day mortality among intensive care unit (ICU) patients diagnosed with sepsis.

Retrospective cohort study.

This study was conducted using data from the Medical Information Mart for Intensive Care IV, a publicly available critical care database from a tertiary care hospital in the US.

A total of 7895 adult ICU patients with sepsis were included between 2008 and 2022. Among them, 3314 (41.97%) had ASCVD, defined by International Classification of Diseases (ICD) codes for coronary artery disease, peripheral artery disease or stroke.

The primary outcomes were all-cause mortality at 30 and 365 days following ICU admission.

ASCVD patients with a greater number of disease beds tend to be male, older, have lower body mass index, heart rates, mean blood pressure, respiratory rate and temperature, compared with non-ASCVD patients. Before propensity-score matching, patients with ASCVD (3314) had significantly higher 30-day (29.21% vs 24.14%, p

Integrated management of sepsis and ASCVD—using targeted interventions such as tailored pharmacotherapy and risk factor modification—may reduce mortality and morbidity in this high-risk population.

Despite growing concerns regarding the impact of smartphone use on adolescents' lifestyle, there is a notable lack of studies utilising national data to explore how smartphone use influences eating habits in this age group. We aimed to investigate the association between smartphone screen time and fast food intake using representative data from Korean adolescents.

Cross-sectional survey.

This cross-sectional analysis used data from the 2017 Korean Youth Risk Behavior Web-based Survey (KYRBS). We used Poisson regression to directly estimate prevalence ratios (PRs) rather than using logistic regression as odds ratios (ORs) tend to overestimate PRs when the outcome is common. Smartphone screen time was categorised into four groups based on the daily time spent using smartphones:

Data from 39 753 individuals were included.

The primary outcome was the frequency of fast food intake, assessed via a self-reported survey that asked: "In the past 7 days, how often did you eat fast food such as pizza, hamburgers, fried chicken, or drink carbonated beverages?". Participants were categorised into two groups based on their median intake: infrequent (≤2 times/week) and frequent (≥3 times/week).

Among 39 753 adolescents, 19 273 reported frequent fast food intake (10 162 (51.9%) boys, 9111 (45.1%) girls), while 20 480 reported infrequent intake (9409 (48.1%) boys, 11 071 (54.9%) girls). The probabilities that adolescents who used smartphones for 6 hours daily would have frequent fast food intake were 1.29 times (95% CI: 1.28 to 1.30) among boys, and 1.43 times (95% CI: 1.42 to 1.44) higher among girls, compared with adolescents who used smartphones for 2 hours daily.

The association between prolonged smartphone screen time and frequent fast food intake in adolescents suggests the need for targeted interventions addressing digital media use to promote healthier eating behaviors.
