'Dear Doctor': a randomised controlled trial of a text message intervention to reduce burnout in trainee anaesthetists.

One in four doctors in training in the UK reports feeling 'burnt out' due to their work and similar figures are reported in other countries. This two-group non-blinded randomised controlled trial aimed to determine if a novel text message intervention could reduce burnout and increase well-being in UK trainee anaesthetists. A total of 279 trainee anaesthetists (Core Training Year 2, Specialty Training Years 3 or 4) were included.

Deformations and Ruptures in Human Lenses With Cortical Cataract Subjected to Ex Vivo Simulated Accommodation.

Purpose: Human cortical opacities are most commonly accompanied by changes in lens fiber structure in the equatorial region at the lens nucleus-cortex interface. Cortex and nucleus have different elastic properties, which change with age. We therefore subjected ex vivo lenses to simulated accommodation and studied the internal deformations to better understand the mechanism of cortical cataract formation.

Identifying the predictors of avoidable emergency department attendance after contact with the NHS 111 phone service: analysis of 16.6 million calls to 111 in England in 2015-2017.

Objectives: To measure the frequency of patients making avoidable emergency department (ED) attendances after contact with NHS 111 and to examine whether these attendances can be predicted reliably.

Design: Analysis of 16 563 946 calls made to 111, where each call was linked with a record of whether the patient attended ED within 24 hours.

Setting: All regions of England from March 2015 to October 2017.

Anterior lens capsule strains during simulated accommodation in porcine eyes.

Experimental protocols have been developed to measure the spatial variation of the mechanical strains induced in the lens capsule during ex vivo lens stretching. The paper describes the application of these protocols to porcine lenses. The deformations and mechanical strains developed in the anterior capsule during each experiment were determined using full field digital image correlation techniques, by means of a speckle pattern applied to the lens surface.

Equatorial wrinkles in the human lens capsule.

Equatorial wrinkles, or crenations, have been previously observed around the equator in coronal images of the human ocular lens. However, wrinkles are typically not apparent when the lens is viewed from saggital directions. In the current paper, the existence and geometry of these wrinkles is shown to be consistent with a mechanical model of the isolated lens, in which the capsule is held in a state of residual tension by a spatially uniform internal pressure.
