Estimating greenhouse gas emissions from the health sector in Canada: Mind the gap.
Healthc Manage Forum
January 2025
University of Toronto, Toronto, Ontario, Canada.
Healthcare is a surprisingly large contributor to climate change, responsible for a significant quantity of global Greenhouse Gas (GHG) emissions. Global commitments to achieve "net zero" health systems, including by the federal government in Canada, suggest a growing need to understand and mobilize capacity for GHG emissions estimation across Canada's health sector. Our analysis highlights efforts by public sector healthcare organizations in Canada to estimate an increasingly broad scope of GHG emissions, building on longstanding efforts to report or reduce energy-related emissions from facilities.

Purpose: Build machine learning (ML) models able to predict pathological complete response (pCR) after neoadjuvant chemotherapy (NAC) in breast cancer (BC) patients based on conventional and radiomic signatures extracted from baseline [F]FDG PET/CT.
Material And Methods: Primary tumor and the most significant lymph node metastasis were manually segmented in baseline [F]FDG PET/CT of 52 newly diagnosed BC patients. Clinical parameters, NAC and conventional semiquantitative PET parameters were collected.
Multiple Protophilic Redox-Active Sites in Reticular Organic Skeletons for Superior Proton Storage.

Protons (H+) with the smallest size and fastest redox kinetics are regarded as competitive charge carriers in the booming Zn-organic batteries (ZOBs). Developing new H+-storage organic cathode materials with multiple ultralow-energy-barrier protophilic sites and super electron delocalization routes to propel superior ZOBs is crucial but still challenging. Here we design multiple protophilic redox-active reticular organic skeletons (ROSs) for activating better proton storage, triggered by intermolecular H-bonding and π-π stacking interactions between 2,6-diaminoanthraquinone and 2,4,6-triformylphloroglucinol nanofibrous polymer.

Commun Biol
January 2025
Institute of Automation, Chinese Academy of Sciences, Beijing, China.
Whether working memory (WM) is encoded by persistent activity using attractors or by dynamic activity using transient trajectories has been debated for decades in both experimental and modeling studies, and a consensus has not been reached. Even though many recurrent neural networks (RNNs) have been proposed to simulate WM, most networks are designed to match respective experimental observations and show either transient or persistent activities. Those few which consider networks with both activity patterns have not attempted to directly compare their memory capabilities.

Eur J Cardiovasc Nurs

Liverpool Centre for Cardiovascular Science, University of Liverpool, Liverpool John Moores University, and Liverpool Heart and Chest Hospital, Liverpool, UK.
Aim: (i) To explore the attitudes of patients with atrial fibrillation (AF) towards oral anti-coagulation (OAC) for stroke prevention post-intracerebral haemorrhage (ICH) and (ii) to explore factors that influence patients' decision-making process for stroke prevention.
Methods And Results: Patients with documented diagnosis of AF and history of a non-traumatic ICH, who were eligible for long-term OAC were recruited from eight hospitals in England, using purposive sampling. Data were collected using semi-structured interviews and analysed using Framework analysis.
