Multicenter Study Observational Study
Effect of regional trauma centralization on volume, injury severity and outcomes of injured patients admitted to trauma centres.
Centralization of complex healthcare services into specialist high-volume centres is believed to improve outcomes. For injured patients, few studies have evaluated the centralization of major trauma services. The aim of this study was to evaluate how a regional trauma network affected trends in admissions, case mix, and outcomes of injured patients. ⋯ MTC designation leads to an increased case volume with considerable implications for operating theatre capacity and bed occupancy. Although no mortality benefit was demonstrated within 6 months of establishing this trauma network, early detectable advantages included improved functional outcome at discharge.

The aim of this review is to introduce the topic of next-generation DNA sequencing, a new technology that is being introduced into clinical practice, and to explain the potential impact for breast cancer surgeons and the wider breast cancer multidisciplinary team. ⋯ The introduction of NGS will have a significant impact on breast cancer services in the near future. Speed of testing will improve in regions of the world where NGS is adopted in place of conventional sequencing, and, as costs decrease, genetic testing will also become accessible and realistic in less well funded health economies. This will create opportunities to improve patient treatment and challenges for the breast cancer multidisciplinary team.

There is a limited evidence base to guide surgeons on the ideal thickness of skin flaps during mastectomy. Here the literature relevant to optimizing mastectomy skin flap thickness is reviewed, including anatomical studies, oncological considerations, factors affecting viability, and the impact of surgical technique and adjuvant therapies. ⋯ The variable and unpredictable thickness of the breast subcutaneous layer means that a single specific universal thickness for mastectomy skin flaps cannot be recommended. It may be that the plane between the subdermal fat and breast parenchyma is a reasonable guide for mastectomy flap thickness, but this may not always correspond to a subcutaneous fascial layer.

Aromatase inhibitors (AIs) are central to the management of oestrogen receptor-positive breast cancer in the adjuvant and metastatic setting. Levels of circulating steroid hormones (SHs) were measured in patients established on AIs to investigate: the influence of body mass index (BMI) in both the adjuvant and metastatic setting; the class of AI utilized in the adjuvant setting (steroidal versus non-steroidal); and differences in SH levels between women treated adjuvantly and those receiving a second-line AI for locally advanced/metastatic disease. ⋯ Residual levels of SH were not significantly influenced by BMI. However, the significant differences in residual SH levels between the second-line and adjuvant AI cohort is of relevance in the context of resistance to AI therapy, and warrants further investigation.
