Patients And Methods: In-stent hemodynamics were studied by transesophageal echocardiography (TEE) in a group of 54 patients after left main coronary artery stenting, during a 6-month follow-up. TEE was performed within 24 hours after stenting and at 1- and 3-month follow-up. Pulsed wave and color Doppler signals were enhanced by IV administration of Levovist.
Results: Angiographic immediate success was obtained in all patients. No in-hospital death occurred. Ten patients (18.4%) complained of recurrent angina at the follow-up of 4.8 ± 1.2 months. Both TEE and coronary angiography confirmed in-stent restenosis in all. Thirty-nine patients (68.5%) remained symptoms free. Mean late loss in these patients was 0.69 ± 0.20 mm. A linear significant positive relation between mean late loss values and diastolic coronary velocity (r: 0.89, P < 0.001) was found. After 3- and 6-month follow-up, PDV showed a significant increase in comparison with basal values (0.7 ± 0.3 and 0.6 ± 0.26 vs. 0.32 ± 0.2 cm/sec, P < 0.01). All patients with restenosis showed a significant increase of diastolic coronary velocity in comparison with basal values (2.89 ± 0.25 cm/sec, P < 0.001).
Conclusion: TEE can predict the development of in-stent intimal hyperplasia in patients with unprotected left main coronary artery stenting.

The relationship between brain and visceral asymmetry: Evidence from situs inversus in humans.
Handb Clin Neurol

Department of Experimental Clinical and Health Psychology, Ghent University, Ghent, Belgium. Electronic address:
This review examines the relationship between visceral and brain asymmetry and explores whether their alignment observed in some vertebrate species also exists in humans. While the development of visceral and brain asymmetry may have occurred for different reasons, it is possible that the basic mechanisms for left-right differentiation of the visceral system were duplicated in the brain. We describe the main phenotypical anomalies and the general mechanism of left-right differentiation in vertebrates, followed by a systematic review of available human studies on behavioral and brain asymmetry in individuals with reversed visceral organization.

Importance: Outcomes in patients with diabetes after fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) using current-generation drug-eluting stents (DES) compared with coronary artery bypass grafting (CABG) are unknown.
Objectives: To investigate the relative treatment effect of PCI vs CABG according to diabetes status with respect to major adverse cardiac and cerebrovascular events (MACCE) at 3 years and to evaluate the impact of the SYNTAX score.
Design, Setting, And Participants: This is a prespecified subgroup analysis of the FAME (Fractional Flow Reserve vs Angiography for Multivessel Evaluation) 3 trial, an investigator-initiated, randomized clinical trial conducted at 48 centers worldwide.
Association of Diet and Waist-to-Hip Ratio With Brain Connectivity and Memory in Aging.
JAMA Netw Open
March 2025
Department of Psychiatry, University of Oxford, Oxford, United Kingdom.
Importance: Epidemiological studies suggest that lifestyle factors are associated with risk of dementia. However, few studies have examined the association of diet and waist to hip ratio (WHR) with hippocampus connectivity and cognitive health.
Objective: To ascertain how longitudinal changes in diet quality and WHR during midlife are associated with hippocampal connectivity and cognitive function in later life.

Objective: To investigate the potential impact of implementing alternatives to opioids (ALTOs) protocol in a community emergency department (ED) in North Texas. We hypothesize that the ALTO protocol is associated with decreased opioid utilization without affecting patient satisfaction to pain control and ED flow.
Design: A retrospective, single-center, cohort study.
COMPARISON OF STENT GEOMETRY ACHIEVED BY DIFFERENT SIDE-BRANCH BALLOONING TECHNIQUES FOR BIFURCATION PROVISIONAL STENTING: THE CRABBIS TRIAL.

Background: "Stepwise provisional stenting" is the most adopted approach for percutaneous coronary interventions (PCI) in bifurcation lesions. During these procedures, side-branch (SB) may deserve treatment, but the best ballooning technique is still undetermined.
Objectives: To compare the stent configurations obtained by two SB ballooning sequences after the main vessel (MV) stent implantation: proximal-optimization-technique (POT)+kissing-balloon-inflation+final POT (PKP) versus POT+isolated-SB-dilation+final POT (PSP).
