AI Article Synopsis
- The study conducted a meta-analysis on the outcomes of Ross/Ross-Konno procedures in neonates and infants, adhering to PRISMA guidelines and using various databases to gather relevant studies.
- The analysis included 587 patients and discovered an early mortality rate of 18.3% and a late mortality rate of 9.7%, with significant variability in outcomes among the studies.
- The findings indicate a notable risk associated with these procedures, emphasizing the need for skilled surgical practices and careful selection of patients, along with the call for further multicenter research.
Article Abstract
Objective: This study aims to perform a meta-analysis of early and late outcomes of the Ross/Ross-Konno procedures in neonates/infants.
Methods: A meta-analysis was performed in accordance with PRISMA guidelines. We used Ovid versions of MEDLINE/PubMed for relevant studies and included those that reported Ross/Ross-Konno operations in neonates/infants and at least one of the predetermined clinical outcomes. and double arcsine methods assessed the heterogeneity between pooled estimates. We used a random-effect model to account for heterogeneity with MetaXL. We calculated point estimates of a pooled estimates along with its 95% CI.
Results: 587 neonate/infant patients were included with median age of 87.5 days old. The follow-up range was five days to 23 years. Early mortality reported in 25 studies with pooled estimates of 18.3% (95% CI: 13.6%-23.5%). Estimates ranged from 0% to 50% with relatively substantial heterogeneity ( = .01, = 48.6%). Late mortality reported in 22 studies with pooled incidence of 9.7% (95% CI: 5.9%-14.3%). Estimates ranged from 0% to 53% with relatively substantial heterogeneity ( = .01, = 46.1%). Autograft reintervention reported in 18 studies with pooled estimate of 19.2% (95% CI: 7.3%-34.5%). Estimates ranged from 0% to 81.8% with high heterogeneity ( < .001, = 90.5%). Right ventricle-to-pulmonary artery conduit reintervention reported in 16 studies with pooled estimates of 32.0% (95% CI: 20.9%-44.12%). Estimates ranged from 0% to 92.3% with high heterogeneity ( < .001, = 75.9%).
Conclusions: The data suggest that the Ross/Ross-Konno procedure in neonates/infants still carries significant risk of early/late mortality and autograft/conduit reintervention. The high variability of results among centers confirms the need for surgical expertise and good patient selection. Prospective multicenter studies are warranted to investigate the rate of autograft reintervention and the impact on long-term survival in this specific population.

Background: Lecanemab, a novel humanized immunoglobulin G1 monoclonal antibody targeting both neurotoxic Aβ protofibrils and Aβ plaques, has demonstrated the ability to substantially reduce markers of amyloid and significantly slow clinical decline on multiple measures of cognition and function in early AD in phase 2 (Study 201) and phase 3 (Clarity AD) studies. In these clinical studies, several plasma biomarkers assessments (Aβ42/40 ratio, p-tau181, GFAP, and p-tau217) showed improvements comparing lecanemab with placebo. Herein, we utilized modelling and simulations to evaluate the long-term effects of lecanemab on biomarkers of neurodegeneration in plasma.

Purpose Of Review: Whether low birth weight (LBW) and preterm delivery (PD) are associated with the risk of developing celiac disease (CD) in children remains unclear. This systematic review and meta-analysis aimed to evaluate the association between LBW and PD with CD development in children.
Recent Findings: We searched PubMed, Embase, Scopus, Web of Science, and Google Scholar databases based on the Mesh terms to find observational studies that investigated the association of LBW and PD with CD development in children up to July 18, 2024.

Background: An estimated ∼40% of dementia cases are due to modifiable risk factors which can be targeted in lifestyle interventions. Effective interventions employ face-to-face delivery, making them resource-intensive and burdensome. Digital interventions offer scalability, accessibility and cost-effectiveness.

Background: Trans-radial coronary angiogram (TR-CAG) has gained popularity due to lower complication rates compared to transfemoral access. Operators can use either conventional catheters, such as Judkins, or single dedicated catheters, such as Tiger-II. This meta-analysis compared the safety and efficacy of Tiger-II versus Judkins catheters in TR-CAG.
