Building capability and community through cyber-incident response exercises.

While a natural disaster or related threat may impact an organisation at some point, it is more likely (even inevitable) that it will be the victim of a cyber attack. The solution to being better prepared for these imminent attacks is to undertake more lightweight and frequent incident response (IR) exercises to help build capabilities and community through a tighter, recurring cycle of planning, conducting and assessing. To boost the facilitation of IR exercises, organisations must leverage the established relationships between business continuity management (BCM) or resilience staff (both of which are familiar with business continuity and disaster recovery exercises), and their information security office.

Ultrasensitive and multiplexed tracking of single cells using whole-body PET/CT.

In vivo molecular imaging tools are crucially important for elucidating how cells move through complex biological systems; however, achieving single-cell sensitivity over the entire body remains challenging. Here, we report a highly sensitive and multiplexed approach for tracking upward of 20 single cells simultaneously in the same subject using positron emission tomography (PET). The method relies on a statistical tracking algorithm (PEPT-EM) to achieve a sensitivity of 4 becquerel per cell and a streamlined workflow to reliably label single cells with over 50 becquerel per cell of F-fluorodeoxyglucose (FDG).

Focal Myositis of the Deltoid Muscle: The Role of Magnetic Resonance Imaging for Diagnosis.

Introduction: Focal myositis is a rare condition first described by Heffner et al., in 1977, as a self-limiting condition of unknown aetiology. It presents as an inflammatory pseudo tumour in skeletal muscle and can present diagnostic difficulty, being commonly mistaken for tissue of vascular, inflammatory, or neoplastic origin.

What are the medicolegal implications of virtual clinics?

Recently there has been increased interest in the use and development of virtual clinics, particularly in the wake of the COVID-19 pandemic. The need to provide clinical care, while minimising patient interaction, has led to wider adoption of both telephone and online consultations, with the potential complications and pitfalls that accompany such a change in practice. A literature search was performed using the Pubmed, MEDLINE and Embase databases, from database inception up to 25 January 2021.

The radiological findings in complex elbow fracture-dislocation injuries.

Elbow fracture-dislocation is a complex injury which can lead to significant bony and soft tissue damage. Surgical intervention is guided towards restoring joint stability, allowing early mobilization and preventing long-term joint stiffness. The most common types are posterolateral, posteromedial, Monteggia type (and variants), and anterior trans-olecranon fracture-dislocations.
