Small mammals (Rattus fuscipes, Mus musculus, Antechinus flavipes, Isoodon obesulus) were livetrapped
for 18 months prior to fuel reduction burning (FRB) in dry sclerophyll forest dominated by
Eucalyptus obliqua south of Adelaide. Although the fire prescription was hotter than that normally
conducted for a FRB in this habitat, the fire was of low intensity, removing most of the litter and
understorey but only singeing the canopy in a few places. Trapping continued for 16 months after the
burn, when the study site was destroyed by a wildfire (Ash Wednesday, 16 February 1983). No animals
were known to have died as a direct result of the FRB and little effect was observed on the population
dynamics of A. flavipes. However, numbers of R. fuscipes declined precipitously in the 3 months
following the FRB and remained at low levels with no summer recruitment of juveniles over the
following 16 months (2 summers) as there had been in the summer prior to the FRB. No movements
to unburned areas were recorded in either species after the FRB. There was no influx of M, musculus
after the fire and there was no marked affect on the population of I. obesulus.

Overwhelming evidence shows that overconsumption of meat is bad for human and environmental health and that moving towards a more plant-based diet is more sustainable. For instance, replacing beef with beans in the US could free up 42% of US cropland and reduce greenhouse gas emissions by 334 mmt, accomplishing 75% of the 2020 carbon reduction target. We summarise the evidence on how overconsumption of meat affects social, environmental and economic sustainability. We summarise the social, environmental and economic effectiveness of a range of dietary interventions that have been tested to date. Because meat eating is embedded within complex cultural, economic, and political systems, dietary shifts to reduce overconsumption are unlikely to happen quickly and a suite of sustained, context-specific interventions is likely to work better than brief, one-dimensional approaches. We conclude with key actions needed by global leaders in politics, industry and the health sector that could help aide this dietary transformation to benefit people and the planet.

Introduction There are 11 500 rectal cancers diagnosed annually in the UK. Although surgery remains the primary treatment, there is evidence that preoperative radiotherapy (RT) improves local recurrence rates. High-quality surgery in rectal cancer is equally important in minimising local recurrence. Advances in MRI-guided prediction of resection margin status and improvements in abdominoperineal excision of the rectum (APER) technique supports a reassessment of the contribution of preoperative RT. A more selective approach to RT may be appropriate given the associated toxicity. Methods and analysis This trial will explore the feasibility of a definitive trial evaluating the omission of RT in resectable low rectal cancer requiring APER. It will test the feasibility of randomising patients to (1) standard care (neoadjuvant long course RT±chemotherapy and APER, or (2) APER surgery alone for cT2/T3ab N0/1 low rectal cancer with clear predicted resection margins on MRI. RT schedule will be 45 Gy over 5 weeks as current standard, with restaging and surgery after 8–12 weeks. Recruitment will be for 24 months with a minimum 12-month follow-up. Objectives Objectives include testing the ability to recruit, consent and retain patients, to quantify the number of patients eligible for a definitive trial and to test feasibility of outcomes measures. These include locoregional recurrence rates, distance to circumferential resection margin, toxicity and surgical complications including perineal wound healing, quality of life and economic analysis. The quality of MRI staging, RT delivery and surgical specimen quality will be closely monitored. Ethics and dissemination The trial is approved by the Regional Ethics Committee and Health Research Authority (HRA) or equivalent. Written informed consent will be obtained. Serious adverse events will be reported to Swansea Trials Unit (STU), the ethics committee and trial sites. Trial results will be submitted for peer review publication and to trial participants.

Advanced Breast Cancer (ABC) is a treatable but still generally incurable disease. The goals of care are to optimize both length and quality of life. Due to continuous research, several advances have been made, particularly for the HER-2-positive and for Luminal-like subtypes. Notwithstanding these advances, median overall survival of patients with ABC is still only 2e3 years, although the range is wide, and survival may be longer for patients treated in specialized institutions. Implementation of current knowledge is highly variable among countries and within each country. The use of treatment guidelines has been associated with a significant improvement in survival. This has been achieved mainly in early breast cancer. For ABC, and particularly metastatic breast cancer (MBC), less level 1 evidence exists and only recently have international consensus guidelines been developed (ABC1 e). The ABC Consensus Conference was created by the European School of Oncology (ESO) with the ambitious goal of improving outcomes for all patients with advanced breast cancer. Backed by strong political advocacy, ABC guidelines are seeking to improve standards of care, to raise awareness about how to best meet to the needs of this underserved group of patients, and to identify research priorities so that clinical research is focused on the most important areas of unmet need. Following the work of the ESO-ABC Task Force, created in 2005, and the successful undertaking of the 1st International Consensus Guidelines Conference on ABC (ABC1), held in November 2011, the 2nd International Consensus Conference for Advanced Breast Cancer (ABC2) took place in Lisbon, Portugal, on ; peer-reviewed
