Ambulatory surgery for Moses™ holmium laser enucleation of the prostate A prospective, real-practice study from a single center.

Introduction: Use of ambulatory holmium laser enucleation of the prostate (HoLEP) is uncommon among Canadian urologists. Our objectives were to determine the feasibility (ambulatory success rate) and safety (early complication rate) of ambulatory HoLEP in a Canadian population.

Methods: We prospectively evaluated consecutive patients from June 2020 to May 2022 presenting for ambulatory HoLEP using Moses™ technology at our institution (MoLEP).

The effect of diabetes on surgical versus percutaneous left main revascularization outcomes: a systematic review and meta-analysis.

Background: The optimal method of coronary revascularization for diabetes mellitus (DM) patients with left main coronary artery disease (LMCAD) is controversial in the drug-eluting stent (DES) era.

Methods: We performed a systematic review and meta-analysis comparing DES-based percutaneous coronary intervention (PCI) to coronary artery bypass grafting (CABG) for LMCAD in DM patients and tested for effect measure modification (EMM) by diabetes for adverse events. We included all randomized controlled trials (RCTs) and observational studies comparing CABG to DES-based PCI including DM patients with LMCAD published up to March 1, 2021.

The feasibility, reliability, and incremental value of two-dimensional speckle-tracking for the detection of significant coronary stenosis after treadmill stress echocardiography.

Background: Two-dimensional speckle-tracking echocardiography (STE) may help detect coronary artery disease (CAD) when combined with dobutamine stress echocardiography. However, few studies have explored STE with exercise stress echocardiography (ESE). We aimed to evaluate the feasibility, reliability, and incremental value of STE combined with treadmill ESE compared to treadmill ESE alone to detect CAD.

Lessons from the implementation of developmental progress assessment: A scoping review.

Objectives: Educators and researchers recently implemented developmental progress assessment (DPA) in the context of competency-based education. To reap its anticipated benefits, much still remains to be understood about its implementation. In this study, we aimed to determine the nature and extent of the current evidence on DPA, in an effort to broaden our understanding of the major goals and intended outcomes of DPA as well as the lessons learned from how it has been executed in, or applied across, educational contexts.

Stimulus-evoked changes in cerebral vessel diameter: A study in healthy humans.

The high metabolic demand of neuronal tissue, coupled with its relatively low energy storage capacity, requires that increases in neuronal activation are quickly matched with increased blood flow to ensure efficient supply of oxygen and nutrients to the tissue. For this to occur, dilation of nearby arterioles must be coordinated with the dilation of larger upstream feeding arteries. As it stands, the exact spatial extent of such dilation in humans is unknown.

Increased BOLD activation in the left parahippocampal cortex after 1 year of medical school: an association with cumulative verbal memory learning.

Although several studies have shown left-right hippocampus asymmetry during learning, it is unclear whether such asymmetry also exists for the parahippocampal cortex, a structure within the limbic system that is also involved in memory and learning. Using a common mental navigation task known to activate the bilateral parahippocampal cortex, this study aimed at determining how BOLD activation in these two areas changes after 1 year of medical school, a program characterized by intensive verbal learning. Fifteen first-year medical students participated in this study and underwent two sessions of functional MRI, at a 1-year interval.
