Faculty, Staff and Student Publications

Introduction: Pain following hepatectomy may delay recovery and increase opioid use. We tested the primary hypothesis that combining lidocaine and low-dose esketamine would reduce movement-evoked pain 24 h after hepatic resection. We also evaluated whether this approach reduced opioid consumption and improved quality of recovery.

Methods: Patients having elective hepatic resections were allocated randomly to receive lidocaine-esketamine or placebo from induction of anaesthesia until the end of surgery. After surgery, patients allocated to lidocaine-esketamine were given a continuous infusion of lidocaine with esketamine for 72 h. All patients received transversus abdominis plane blocks with ropivacaine 2 mg.kg-1 after induction of …

Jones, Robert Kob, Suzanne N. Morin, Girish N, Lucas B.R. Orssatto, Maria Pearson, Daniel Pinto, Esmee M. Reijnierse, Catherine M. Said, Mohamed Salem, Gary Skinner

Research outputs 2022 to 2026

Background: Remote methods may help older adults improve their physical function, but understanding the perspectives of experts who deliver this care is critical. This modified Delphi process aimed to develop expert consensus on effectiveness, feasibility and implementation of remote assessment and management of physical function in older adults. Methods: This online Delphi process included experts involved in supporting older adults to maintain or improve their health. The Round 1 survey presented 33 Delphi statements assessed using an 11-point Likert scale (0–10; ≥7 indicated agreement). Statements with strong (≥80 %), moderate (50–<80 %) and low (<50 %) agreement were accepted, revised, or rejected, respectively. Revised statements were presented in Round 2, and accepted statements were consolidated into key messages. Results: In total, 108 respondents (67 % female; mean [SD] age 41.4 [10.9] years) from 16 countries (five continents) completed Round 1. Fourteen statements were accepted (88–100 % agreement) and 10 were rejected (8–39 % agreement). The remaining nine statements (52–69 % agreement) were revised, and two new statements were developed for Round 2, which was completed by 89 (82 %) respondents. Five Round 2 statements were accepted (82–93 % agreement). Seven key messages were developed from 19 accepted statements, highlighting that remote care should be accessible to older adults with requisite capabilities, is feasible for older adults and health professionals with adequate support and training, and requires guidelines, policies, and further research to support wider adoption. Conclusions: The findings of this Delphi process can inform the implementation of remote care approaches for assessing and managing physical function in older adults.

Tau Seeds Induce Neurofibrillary Tangle Formation Across Brain Regions Via Individual-Specific Connectivity, Audrey J Weber, Bernard Ng, Kelsey M Greathouse, David A Bennett, Shinya Tasaki, Chris Gaiteri, Jeremy H Herskowitz

Faculty, Staff and Student Publications

The spread of tau pathology across the cerebral cortex is closely tied to cognitive decline in Alzheimer's disease (AD). To investigate mechanisms underlying tau spread, we measured bioactivity of tau seeds from inferior temporal gyrus (ITG) and superior frontal gyrus (SFG) synaptosomes in 128 individuals and demonstrated that tau seed bioactivity associates with tau phosphorylation, neurofibrillary tangles (NFTs), and cognitive impairment. Incorporating genotype data from the same individuals within a Mendelian randomization framework showed that tau seeds in ITG induce NFTs locally as well as drive tau seeds and NFTs in SFG. Integrating antemortem functional magnetic resonance imaging data from …

High-Order Brain Interactions During Ketamine-Induced State Changes: A Functional Marker Of Response In Late-Life Treatment-Resistant Depression?, Krisha Shah, Rubén Herzog, Alan C Swann, Brittany O'Brien, Rahul Balakrishnan, Sanjay J Mathew, Nicholas Murphy

Faculty, Staff and Students Publications

Ketamine is a fast-acting intervention for treatment-resistant depression (TRD), yet only a subset of patients show robust clinical response, and the underlying neural mechanisms remain unclear. High-order interactions (HOI) derived from multivariate information theory provide a framework for examining nonlinear dependencies among brain regions beyond pairwise connectivity. One such metric, the O-information, captures the balance between synergistic and redundant interactions across three or more variables. In this secondary analysis of a randomized, double-blind, midazolam-controlled trial (NCT02556606), we examined EEG-derived HOI in 30 late-life veterans with TRD following a single 40-minute intravenous infusion of ketamine (0.1, 0.25, 0.5 mg/kg; n = …
