The center of pressure (COP) position reflects a combination of proprioceptive, motor and mechanical function. As such, it can be used to quantify and characterize neurologic dysfunction. The aim of this study was to describe and quantify the movement of COP and its variability in healthy chondrodystrophoid dogs while walking to provide a baseline for comparison to dogs with spinal cord injury due to acute intervertebral disc herniations. Fifteen healthy adult chondrodystrophoid dogs were walked on an instrumented treadmill that recorded the location of each dog's COP as it walked...

BACKGROUND: Nowadays more and more employees are required to perform emotional labor (EL) which means that they need to express emotions set by the organizational procedures, simultaneously masking the true feelings. Employees, while performing emotional labor, choose between one of the two strategies (surface acting or deep acting) and this leads to e.g., burnout. As the performance of emotional labor and its consequences depend on the specification of work and chosen strategy, it was assumed that the consequences of EL may be different for workers in various occupations...

Spontaneous, acute, complete thoracolumbar spinal cord injury (TL-SCI) in dogs frequently results in permanent deficits modeling chronic paralysis in people. Recovery of walking without recovery of sensation has been interpreted in dogs as reflexive spinal walking. To evaluate this assumption, this study characterized the electrophysiological status of motor and sensory long tracts and local reflex circuitry in dogs with absent recovery of sensation after acute TL-SCI and correlated findings to gait scores...

CONTEXT: Burnout impacts adversely on professional and personal life, and holds implications for patient care. Current research on burnout mainly focuses on established general practitioners but it is unclear how early the signs of burnout really start. This work seeks to identify whether specific GP trainee groups are particularly at risk of burnout and the aspects of training they find stressful. METHODS: A longitudinal cohort study, collecting qualitative and quantitative data through a single mode of data collection (questionnaire) took place with trainees from all GP training years (ST1-3), across a vocational training scheme (n = 48)...
