AI Article Synopsis
- The study investigates long-term health outcomes of young patients (60 and under) with coronary artery disease, comparing two treatment strategies: CABG (coronary artery bypass grafting) and PCI (percutaneous coronary intervention).
- Results indicate that CABG is associated with lower all-cause death rates and fewer new revascularizations and hospital readmissions over a median follow-up of 9.3 years, although it had a higher risk of death/stroke in the first 30 days post-procedure.
- The findings suggest that for young patients with low-complexity coronary anatomy, CABG may offer better long-term health outcomes compared to PCI, despite an initial increase in short-term risks.
Article Abstract
Objectives: Age is an important factor weighing on revascularization decisions. We analysed long-term health outcomes of young patients with low-complexity coronary anatomy suitable for both coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI), according to revascularization strategy.
Methods: Patients 60 years old or less, undergoing invasive coronary angiography between January 2007 and December 2015, presenting with proximal left anterior descending artery involvement, left main or multivessel disease and a SYNTAX Score ≤22 were retrospectively selected. An inverse probability of treatment weight methodology generated a pseudopopulation with well-balanced characteristics, which was used to estimate the average treatment effect between PCI (n = 374) and CABG (n = 173).
Results: Mean age was 53 ± 7 years old, 27% had diabetes mellitus and 48% presented with an acute coronary syndrome. Mean SYNTAX score was 13.6 ± 4.9 and 68% underwent PCI as index revascularization strategy. In the weighed population, the adjusted hazard of the primary end-point of all-cause death at total follow-up (median 9.3 years; interquartile range 6.9-11.7) was 0.40 (95% confidence interval 0.19-0.7) for CABG vs PCI (incidence rate 5.8 vs 14.0 deaths/1000-person-years). Accounting for death as competing risk, the cumulative hazard of new revascularization (sub-distribution hazard ratio 0.72; 95% confidence interval 0.32-1.25) and any cause hospital readmission (sub-distribution hazard ratio 0.70; 95% confidence interval 0.41-1.07) were lower in CABG patients, as opposed to death/stroke rates at 30 days which were higher with CABG (0.3% vs 1.7%; risk ratio = 5.84).
Conclusions: In this quasi-experimental analysis of young patients with coronary artery disease and an equivalent indication for both PCI and CABG, long-term health outcomes were favourably associated with CABG, as compared to PCI. These observations support the need for dedicated randomized trials with longer follow-up in order to better inform lifetime treatment options.

Purpose: Congenital pseudarthrosis of the tibia (CPT) is a rare condition typically manifesting within the first decade of life. The primary objectives of surgical intervention for CPT include achieving long-term bony union of the tibia, preventing or minimizing limb length discrepancies (LLD), avoiding mechanical axis deviations of the tibia and adjacent joints, and preventing refracture. This study aims to conduct a systematic review of current treatment methods for CPT to determine the most effective non-surgical and surgical management strategies for pediatric patients with this condition.

Background: Psilocybin therapy (PT) produces rapid and persistent antidepressant effects in major depressive disorder (MDD). However, the long-term effects of PT have never been compared with gold-standard treatments for MDD such as pharmacotherapy or psychotherapy alone or in combination.
Methods: This is a 6-month follow-up study of a phase 2, double-blind, randomised, controlled trial involving patients with moderate-to-severe MDD.

Background: The WHO has highlighted that: "promotion of e-cigarettes has led to marked increases in e-cigarette use by children and adolescents." The long-term neuropsychiatric and psychological consequences of substance abuse in adolescence is well recognised. Limited data exists on the adolescent burden of vaping-related nicotine addiction and behavioural and/or psychological dependence to guide pharmacological or behavioural interventions to stop electronic cigarette usage.
