Background: Electrographic flow (EGF) mapping allows for the visualization of global atrial wavefront propagations. One mechanism of initiation and maintenance of atrial fibrillation (AF) is stimulation from EGF-identified focal sources that serve as driver sites of fibrillatory conduction. Electrographic flow consistency (EGFC) further quantifies the concordance of observed wavefront patterns, indicating that a healthier substrate shows more organized wavefront propagation and higher EGFC.

Fertility preservation in female cancer patients: Surgical procedures.

Int J Gynaecol Obstet

January 2025

Department of Obstetrics and Gynecology, McGill University, Montreal, Quebec, Canada.

The surgical management of cancer patients wishing fertility preservation is multidisciplinary, involving surgeon, anesthetist, hematologist, and nursing and laboratory staff. Many oncology patients have a multitude of medical or surgical conditions that require careful planning of all therapy including surgical removal of reproductive material, either oocytes or ovarian tissue. The significant risks related to either transvaginal or abdominal surgery should be discussed and documented and the final decision to proceed must be balanced against the risks, including death.

RNA-specific nucleotidyltransferases (rNTrs) add nontemplated nucleotides to the 3 end of RNA. Two noncanonical rNTRs that are thought to be poly(A) polymerases (PAPs) have been identified in the mitochondria of trypanosomes - KPAP1 and KPAP2. KPAP1 is the primary polymerase that adds adenines (As) to trypanosome mitochondrial mRNA 3 tails, while KPAP2 is a non-essential putative polymerase whose role in the mitochondria is ambiguous.

Focusing on antimicrobial resistant infections -are we missing the forest for the trees and the patients for pathogens?

Front Antibiot

December 2023

Clinical Research Directorate, Frederick National Laboratory for Cancer Research, Frederick, MD, United States.

Antimicrobial resistance (AMR) is a challenge because it is associated with worse patient outcomes. To solve the problem will take development of interventions and policies which improve patient outcomes by prolonging survival, improving patient symptoms, function and quality of life. Logically, we should look to focusing resources in areas that would have the greatest impact on public health.

Clouds reduce downwelling longwave radiation over land in a warming climate.

Nature

January 2025

Department of Atmospheric and Oceanic Sciences, McGill University, Montreal, Quebec, Canada.

Clouds greatly influence the Earth's energy balance. Observationally constraining cloud radiative feedback, a notably uncertain climate feedback mechanism, is crucial for improving predictions of climate change but, so far, remains an elusive objective, and the feedback may be different over the ocean versus over land. Here we show a local negative surface longwave cloud feedback over land at the southern Great Plains site, constrained by direct long-term observation of spectrally resolved downwelling longwave radiance.
