A tax on sugar sweetened beverages in Colombia: Estimating the impact on overweight and obesity prevalence across socio economic levels.
Colombia has a high prevalence of overweight (56%) and obesity (19%) among adults and is experiencing a growing trend in the prevalence of associated chronic conditions. Evidence suggests that sugar sweetened beverages (SSB) are associated to overweight/obesity, and that taxes on these beverages could reduce their associated health consequences. This paper assesses the potential effect of different levels of a SSB tax in Colombia on overweight and obesity prevalence. ⋯ The results of this study suggest that a SSB tax could reduce the overweight and obesity prevalence in Colombia, especially among lower SES households. This study shows that SSB taxes have a particularly beneficial effect in the most vulnerable population. Additional social and individual benefits, or individual costs arising from the tax are not assessed in this research, implying that even larger health gains could be observed.

Organs and organisations: Situating ethics in organ donation after circulatory death in the UK.
Controlled organ donation after circulatory death (DCD) has recently been revived in the UK, as part of attempts to increase organ donation rates. The re-introduction of DCD has subsequently become the focus of bioethical controversy, since it necessitates intervening in the care of dying patients to obtain quality donor organs. Transplant policy responses to these concerns have generated new legal and ethical guidelines to address uncertainties around DCD, producing claims that the UK has overcome' the ethical challenge of DCD. ⋯ I describe how these issues are worked-around by creating conditions to make DCD organisationally possible, and through the animation of standard procedures into acceptable forms of practice. I argue that ethics in DCD go far beyond normative bioethical principles, to encompass concerns around: the reputation of hospital Trusts, public perceptions of organ donation, the welfare of potential donor families, and challenges to the work of health professionals caring for dying patients. The paper enriches understanding of ethics in science and medicine by showing how ethics are assembled and negotiated as a practical-organisational concern, and calls for further examination of how DCD gets constructed as a potential problem and is made to happen in practice.

Structural stigma and the health and wellbeing of Australian LGB populations: Exploiting geographic variation in the results of the 2017 same-sex marriage plebiscite.
Lesbian, gay, or bisexual (LGB) people experience poorer life outcomes than heterosexual people, with ongoing debates about the aetiology of these differences. Minority stress theory draws attention to the importance of structural stigma, which concerns hostile social environments for sexual minorities that constrain their opportunity structures. Yet few studies have operationalised structural stigma and tested its influence, with most focusing on the US context; even fewer studies examine the underlying mechanisms. ⋯ These findings have significant implications for policy and practice, highlighting the need for interventions aimed at reducing community levels of structural stigma and increasing social support to LGB populations.
