Protocol for black student well-being study: a multi-site qualitative study on the mental health and well-being experiences of black UK university students.

Introduction: There is an increasing concern about the mental health and mental well-being of university students in the UK. Black university students who report a mental health condition are less likely to complete their course, achieve a first-class or upper second-class degree and progress to further education. This study will document black university students' accounts of their mental health experiences and perceptions of key turning points of biographical changes to their mental health as they move through the university life cycle.

Modelling multiple laser pulses for port wine stain treatment.

Many port wine stains (PWS) are still resistant to pulsed dye laser treatment. However, anecdotal information suggests that multiple-pulse laser irradiation improves patient outcome. Our aims in this note are to explain the underlying mechanism and estimate the possible thermal effects of multiple pulses in vascular structures typical of PWS.

Bioheat transfer analysis of cryogen spray cooling during laser treatment of port wine stains.

Background And Objective: The thermal response of port wine stain (PWS) skin to a combined treatment of pulsed laser irradiation and cryogen spray cooling (CSC) was analyzed through a series of simulations performed with a novel optical-thermal model that incorporates realistic tissue morphology.

Study Design/materials And Methods: The model consisted of (1) a three-dimensional reconstruction of a PWS biopsy, (2) a Monte Carlo optical model, (3) a finite difference heat transfer model, and (4) an Arrhenius thermal damage calculation. Simulations were performed for laser pulses of 0.

Modeling laser treatment of port wine stains with a computer-reconstructed biopsy.

Background And Objective: The efficacy of laser treatment of port wine stains (PWS) has been shown to be highly dependent on patient-specific vasculature. The effect of tissue structure on optical and thermal mechanisms was investigated for different pulse durations by using a novel theoretical model that incorporates tissue morphology reconstructed tomographically from a PWS biopsy.

Study Design/materials And Methods: An optical-thermal numerical model capable of simulating arbitrarily complex, three-dimensional tissue geometries was developed.
