The purpose of this study was to assess trends in ABOS part II candidate's operative management of geriatric (≥65 years) proximal humerus fractures over the 2010-2020 decade. ⋯ Despite the rapid growth of both the elderly population and related geriatric proximal humerus fractures, ABOS candidates are treating less with surgery. There has been approximately a 37% decrease in the total number of operatively treated proximal humerus fractures between the first and second half 2010-2020 decade. When operative treatment is performed, there is a trend towards ORIF over an arthroplasty. Trauma fellowship trained surgeons are less likely to perform an arthroplasty as compared to other subspecialties. The Southeast region is least likely to perform an arthroplasty as compared to the Midwest or Northeast.

Until now, it has remained difficult for doctors to make an informative decision as to which concentration of hypertonic saline (HTS) is more beneficial for patients with traumatic brain injury (TBI). We therefore investigate the effect of different concentrations of hypertonic saline on mortality and ICP lowering efficacy in this group of patients. ⋯ Among patients with TBI, the application of 5% HTS was associated with decreased all-cause mortality compared with mannitol and other concentration. Treatments with 10% and 15% HTS was more likely to decrease ICP compared with other fluids. More trials are needed to verify the current findings.

In this article we discuss the evolution of computers and the use of VR for trauma education. We reflect on available literature and share the lessons we learned. VR allows you to share your most interesting and rare patient cases with a bedside teaching experience. ⋯ Based on our experience we advise to limit VR educational sessions to a maximum of one hour. Although the VR techniques currently have some limitations, the quality and possibilities of this technique are rapidly improving. VR education will certainly be a part of trauma education in the future; Be prepared!

Traumatic brain injury (TBI) is the most significant cause of death and disability resulting from major trauma. The aim of this study is to describe the demographics of TBI patients, the current pathways of care and outcomes in the Republic of Ireland from 2014 to 2019. ⋯ This population-based study bench marks the 'as is' for patients with TBI in Ireland. We found that presently in Ireland, the mortality rate from severe TBI appears to be higher than that reported in international literature, and only a minority of severe TBI patients are brought directly from the incident to a neurosurgical centre. The new major trauma system should focus on providing effective and efficient access to neurosurgical, neuro-critical and neuro-rehabilitative care for patients who sustain TBI.

The mechanical properties and microstructure of brain tissue, as its two main physical parameters, could be affected by mechanical stimuli. In previous studies, microstructural alterations due to mechanical loading have received less attention than the mechanical properties of the tissue. Therefore, the current study aimed to investigate the effect of ex-vivo mechanical forces on the micro-architecture of brain tissue including axons and glial cells. ⋯ Moreover, the results revealed that in both loading steps, the maximum cell-cell distance occurred at 15% strain, and this distance decreased for higher strains. Since 15% strain is close to the previously reported brain injury threshold, this evidence could suggest that at higher strains, the axons start to rupture, causing a reduction in the displacement of glial cells. Accordingly, it was concluded that more attention to glial cells' architecture during mechanical loading may lead to introduce a new biomarker for brain injury.
