Appropriateness of lumbar spine imaging in patients presenting to the emergency department with low back pain in a Western Australian tertiary hospital.
Intern Med J
January 2025
Preventive Medicine, Monash University, Melbourne, Victoria, Australia.
Background: The Australian Rheumatology Association identified the use of imaging in patients with low back pain without indication of serious pathology as a low-value practice.
Aims: To determine the appropriateness of diagnostic lumbar spine imaging requests in patients with low back pain presenting to a Western Australian hospital's emergency department.
Methods: We conducted a retrospective review of all adult patients (18 years and older) who presented with low back pain to the Fiona Stanley Hospital emergency department from 1 July 2020 to 31 December 2020.
Real-Time Subcutaneous Arterial Navigation for Thinning of an Anterolateral Thigh Flap Using Photoacoustic Imaging and Projection Mapping: A Case Report.

Thinning of anterolateral thigh flap is challenging. Anatomical studies have shown variations in arterial branching patterns in the subcutaneous layer, which were suspected to be the reason for the high frequency of thinning failures. We attempted to visualize subcutaneous arterial courses preoperatively and perform thinning of perforator flaps using this information appropriately.

As development of new oncology small molecule therapies is focused mainly on molecularly targeted agents, the dose selection paradigm has shifted from the maximum tolerated dose (MTD)-based approach traditionally utilized with cytotoxic drugs towards determining an optimal dose with long-term tolerability while maintaining efficacy. To assess overall tolerability in recently approved oncology small molecules, we surveyed 54 compounds approved by the FDA since March 2017 with respect to dose intensity, dose modifications, and treatment emergent adverse events (TEAEs). Of the 54 new molecular entities surveyed, only 15 were approved at a label dose equal to the MTD (Label Dose = MTD).

The mitochondrial outer membrane (OMM) β-barrel proteins link the mitochondrion with the cytosol, endoplasmic reticulum, and other cellular membranes, establishing cellular homeostasis. Their active insertion and assembly in the outer mitochondrial membrane is achieved in an energy-independent yet highly effective manner by the Sorting and Assembly Machinery (SAM) of the OMM. The core SAM constituent is the 16-stranded transmembrane β-barrel Sam50.
