Slipping Through the Cracks? Concussion Management in Aotearoa New Zealand Secondary Schools.

Background: Concussion-related guidelines appear to be inconsistently implemented in secondary schools in Aotearoa New Zealand. The purpose of this qualitative Participatory Action Research study was to describe key school stakeholders' perceptions of their current concussion management processes.

Methods: Seventeen focus groups, two dyad, and nine individual interviews were conducted with stakeholders (n = 95) from six secondary schools and healthcare clinics, exploring their perceptions of barriers and facilitators to concussion management.

The Winchcombe meteorite, a unique and pristine witness from the outer solar system.

Direct links between carbonaceous chondrites and their parent bodies in the solar system are rare. The Winchcombe meteorite is the most accurately recorded carbonaceous chondrite fall. Its pre-atmospheric orbit and cosmic-ray exposure age confirm that it arrived on Earth shortly after ejection from a primitive asteroid.

The interaction of oestrogen receptor status and pathological features with adjuvant treatment in relation to survival in patients with operable breast cancer: a retrospective study of 2660 patients.

The oestrogen receptor (ER) status of 2660 patients with primary breast cancer has been related to the effect of different adjuvant systemic therapies on survival. However, as patients in the various treatment groups also had different prognostic features comparison between treatments was difficult. Over 90% of patients receiving tamoxifen (Tam) were postmenopausal compared with <20% of those receiving chemotherapy (CT).
