PURPOSE: To characterise the impact of monofocal soft contact lens (SCL) and bifocal SCLs on refractive error, depth of focus (DoF) and orientation of blur in the peripheral visual field. METHODS: Monofocal and two bifocal SCLs, Acuvue Bifocal (AVB, Johnson & Johnson) and Misight Dual Focus (DF, CooperVision) with +2.0 D add power were modelled using a ray tracing program (ZEMAX) based on their power maps. These SCLs were placed onto the anterior corneal surface of the simulated Atchison myopic eye model to correct for -3...

PURPOSE: Myopia progression is thought to involve biomechanical weakening of the sclera, which leads to irreversible deformations and axial elongation of the eye. Scleral crosslinking has been proposed as a potential treatment option for myopia control by strengthening the mechanically weakened sclera. The biomechanical mechanism by which the sclera weakens during myopia and strengthens after crosslinking is not fully understood. Here, we assess the effect of lens-induced myopia and exogenous crosslinking using genipin on the inelastic mechanical properties of the tree shrew sclera measured by cyclic tensile tests...

CASE REPORT: A 6-year-old speyed female Bull Arab-cross dog was found to have a small tonsillar nodule. Histological examination revealed a well-differentiated mast cell tumour (MCT). At initial staging, no evidence of concurrent cutaneous or visceral MCTs was found on a complete blood count, a single lateral thoracic radiograph, abdominal ultrasound or cytology of the spleen and regional lymph nodes. A diagnosis of primary tonsillar MCT was made. At 40 months postoperatively, the dog is alive with no evidence of gross tumour progression, in contrast to some previous reports of rapid disease progression and metastasis in dogs with primary oral MCTs...

BACKGROUND: Filaggrin is central to the pathogenesis of atopic dermatitis (AD). The cheeks are a common initiation site of infantile AD. Regional and temporal expression of levels of filaggrin degradation products (natural moisturising factors, NMF), activities of filaggrin processing enzymes (bleomycin hydrolase; BH and calpain-1; C-1) and plasmin, and corneocyte envelope (CE) maturity in early life are largely unknown. OBJECTIVES: We did a cross-sectional, observational study investigating regional and age dependent variations in NMF levels, activity of proteases and CE maturity in stratum corneum (SC) from infants to determine if these could explain the observed predilection sites for AD in early life...

Electrosurgery is widely used in various surgical operations. When tissue is cut with high-frequency current, the cell contents at the incision area evaporate and together with water and possible soot particles, form surgical smoke. The smoke contains cell metabolites, and therefore, possible biomarkers for cancer or bacterial infection. Thus, the analysis of surgical smoke could be used in intraoperative medical diagnostics. We present a method that can be used to detect the characteristics of various tissue types by means of differential ion mobility spectrometry (DMS) analysis of surgical smoke...

EDITORIAL
Rachel Mason Dentinger, Abigail Woods
Comparison between different animal species is omnipresent in the history of science and medicine but rarely subject to focussed historical analysis. The articles in the "Working Across Species" topical collection address this deficit by looking directly at the practical and epistemic work of cross-species comparison. Drawn from papers presented at a Wellcome-Trust-funded workshop in 2016, these papers investigate various ways that comparison has been made persuasive and successful, in multiple locations, by diverse disciplines, over the course of two centuries...

BACKGROUND: Numerous epidemiological studies among health care staff have documented associations of adverse psychosocial working conditions with poorer health-related outcomes, a reduced quality of patient care and intentions to leave the profession. The evidence for physician assistants in Germany remains limited though. METHODS: We surveyed a total of 994 physician assistants between September 2016 and April 2017. Psychosocial working conditions were measured by the established effort-reward imbalance (ERI) questionnaire and by a questionnaire specifically developed to capture psychosocial working conditions among physicians...
