Background: Although there is a known correlation between obesity and revision risk following total knee arthroplasty (TKA), there is an ongoing debate regarding the appropriateness of denying TKA solely based on the body mass index (BMI) of a patient. Our aim was to determine whether a patient's American Society of Anesthesiologists (ASA) class predicts their risks of early all-cause revision and revision for periprosthetic joint infection (PJI) following primary TKA, independent of their BMI.
Methods: Data from the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) were obtained regarding all patients who underwent primary TKA for osteoarthritis in Australia from January 1, 2015, to December 31, 2022.
Background: There is evidence that iron metabolism may play a role in the underlying pathophysiological mechanism of migraine. Studies using (=1/ ) relaxometry, a common MRI-based iron mapping technique, have reported increased values in various brain structures of migraineurs, indicating iron accumulation compared to healthy controls.
Purpose: To investigate whether there are short-term changes in during a migraine attack.
Background: The pathogenesis of spontaneous cervical artery dissection remains unclear, and no established predictors of recurrence exist. Our goal was to investigate the potential association between cervical artery tortuosity, a characteristic of patients with connective tissue disorder, and spontaneous cervical artery dissection.
Methods: The ReSect study (Risk Factors for Recurrent Cervical Artery Dissection) is an observational study that invited all spontaneous cervical artery dissection patients treated at the Innsbruck University Hospital between 1996 and 2018 for clinical and radiological follow-up.
Background: Given growing demand for hip and knee arthroplasty and unsustainable resource requirements, safe and efficient models of care are critical. This study aims to determine the impact on healthcare costs of implementing an enhanced short-stay model of care (ESS-MOC) for arthroplasty at a national level.
Methods: A budget impact analysis was conducted for the years 2023-2030 in the setting of Australian publicly and privately funded hospitals performing hip or knee arthroplasty.
Article Synopsis
- - The study investigates the urgent need for effective ways to diagnose and track Alzheimer’s disease (AD) by focusing on memory issues and brain changes, particularly in those with mild to moderate AD dementia (ADD).
- - Researchers followed 104 ADD patients over several years using MRI scans and cognitive tests to analyze brain structure and cognitive decline, finding a strong link between gray matter loss in the temporal lobe and difficulties with word learning.
- - The findings indicate that certain brain atrophy patterns, specifically in the temporal lobe, combined with specific cognitive test deficits, could help predict quicker cognitive decline in AD patients.
