BMC Musculoskelet Disord

February 2024

Cumming School of Medicine, Health Sciences Centre, University of Calgary, 3330 Hospital Drive NW, Foothills campus, Calgary, AB, T2N 4N1, Canada.

Background: Decision aids can help patients set realistic expectations. In this study, we explored alternative presentations to visualise patient-reported outcomes (EQ-5D-5L) data within an online, individualized patient decision aid for total knee arthroplasty (TKA) that, in part, generates individualized comparisons based on age, sex and body mass index, to enhance usability prior to implementation into routine clinical practice.

Methods: We used data visualization techniques to modify the presentation of EQ-5D-5L outcomes data within the decision aid.

Article Synopsis
  • - The study examines the balance between sample size and scan time in neuroimaging, particularly in brain-wide association studies (BWAS) using fMRI, and finds that total scan duration significantly affects prediction accuracy, suggesting they can be interchangeable up to 20-30 minutes.
  • - As scan time increases, its relative benefits diminish compared to sample size, indicating that longer scan times should be considered, especially when accounting for participant-related costs like recruitment and non-imaging measures.
  • - The research highlights that conventional methods prioritize sample size over scan time, potentially leading to poorer prediction accuracies; thus, it provides recommendations for optimizing future study designs to make better resource use.

Purpose: The primary objective was to establish whether blood-based leucine-rich alpha-2-glycoprotein (LRG1) can predict outcomes in patients with locally advanced prostate cancer undergoing androgen-deprivation therapy (ADT) and radiotherapy (RT) and to determine how it may relate to 92 immune-oncology (I-O)-related proteins in this setting.

Methods: Baseline blood level of LRG1 from patients treated with ADT and RT enrolled in the CuPCa (n = 128) and IMRT (n = 81) studies was measured using ELISA. A longitudinal cohort with matched blood samples from start of ADT, start of RT, and end of RT protocol from 47 patients from the IMRT cohort was used to establish levels of I-O proteins by high-multiplexing Proximal Extension Assay by Olink Proteomics.

A Scalar Approach to Vaccination Ethics.

J Ethics

September 2023

Wellcome Centre for Ethics and Humanities, Big Data Institute, University of Oxford, Li Ka Shing Centre for Health Information and Discovery, Old Road Campus, Oxford, OX3 7LF UK.

Should people get vaccinated for the sake of others? What could ground-and limit-the normative claim that people ought to do so? In this paper, we propose a reasons-based consequentialist account of vaccination for the benefit of others. We outline eight harm-based and probabilistic factors that, we argue, give people moral reasons to get vaccinated. Instead of understanding other-directed vaccination in terms of binary moral duties (i.

Biomacromolecules

March 2024

Department of Chemical and Materials Engineering, Donadeo Innovation Centre for Engineering, University of Alberta, 9211-116 Street NW, Edmonton, AB T6G 1H9, Canada.

Article Synopsis
  • Beta cell replacement therapies in the subcutaneous space offer benefits like easier access, noninvasive monitoring, and simpler graft removal compared to other locations.
  • Research on prevascularized subcutaneous sites showed that the pre-formed blood vessel barriers help retain injected poly(ethylene oxide)s (PEOs) more effectively than unmodified sites.
  • Findings reveal that larger molecules (greater than 35 kDa) struggle to enter circulation from these sites, emphasizing the importance of molecular size for improving the survival of beta cell grafts.

Spatial confidence regions for combinations of excursion sets in image analysis.

J R Stat Soc Series B Stat Methodol

February 2024

Nuffield Department of Population Health, Big Data Institute, Li Ka Shing Centre for Health Information and Discovery, University of Oxford, Oxford, UK.

The analysis of excursion sets in imaging data is essential to a wide range of scientific disciplines such as neuroimaging, climatology, and cosmology. Despite growing literature, there is little published concerning the comparison of processes that have been sampled across the same spatial region but which reflect different study conditions. Given a set of asymptotically Gaussian random fields, each corresponding to a sample acquired for a different study condition, this work aims to provide confidence statements about the intersection, or union, of the excursion sets across all fields.

The linear mixed-effects model (LME) is a versatile approach to account for dependence among observations. Many large-scale neuroimaging datasets with complex designs have increased the need for LME; however LME has seldom been used in whole-brain imaging analyses due to its heavy computational requirements. In this paper, we introduce a fast and efficient mixed-effects algorithm (FEMA) that makes whole-brain vertex-wise, voxel-wise, and connectome-wide LME analyses in large samples possible.

The maintenance of genome stability is crucial for cell homeostasis and tissue integrity. Numerous human neuropathologies display chronic inflammation in the central nervous system, set against a backdrop of genome instability, implying a close interplay between the DNA damage and immune responses in the context of neurological disease. Dissecting the molecular mechanisms of this crosstalk is essential for holistic understanding of neuroinflammatory pathways in genome instability disorders.

DNA Methylation-Based Assessment of Cell Composition in Human Pancreas and Islets.

Diabetes

April 2024

Department of Developmental Biology and Cancer Research, The Institute for Medical Research Israel-Canada (IMRIC), Hebrew University-Hadassah Medical School, Jerusalem, Israel.

Assessment of pancreas cell type composition is crucial to the understanding of the genesis of diabetes. Current approaches use immunodetection of protein markers, for example, insulin as a marker of β-cells. A major limitation of these methods is that protein content varies in physiological and pathological conditions, complicating the extrapolation to actual cell number.

Article Synopsis
  • Immunotherapy using PD-(L)1 blockade is common for treating non-small cell lung cancer (NSCLC), but over 60% of initial responders develop acquired resistance.
  • Research indicates that this resistance is linked to differences in inflammation and interferon (IFN) signaling, with relapsed tumors showing varied expressions of IFNγ response genes.
  • Understanding the altered IFN response in these tumors may help develop new strategies to overcome resistance and improve treatment effectiveness.
