RESUMO

Despite evidence that dietary population health interventions are effective and widely accepted, they remain the topic of intense debate centring on the appropriate role of the state. This review sought to identify how the role of the state in intervening in individuals' food practices is conceptualized across a wide range of literatures. We searched 10 databases and 4 journals for texts that debated dietary population health interventions designed to affect individuals' health-affecting food practices. Two co-authors independently screened these texts for eligibility relative to inclusion and exclusion criteria. Thirty-five texts formed our final corpus. Through critical reflexive thematic analysis (TA), we generated 6 themes and 2 subthemes concerning choice, responsibility for health, balancing benefits and burdens of intervention, the use of evidence, fairness, and the legitimacy of the state's actions. Our analysis found that narratives that aim to prevent effective regulation are entrenched in academic literatures. Discourses that emphasized liberty and personal responsibility framed poor health as the result of 'lifestyle choices'. Utilitarian, cost-benefit rationales pervaded arguments about how to best balance the benefits and burdens of state intervention. Claims about fairness and freedom were used to evoke powerful common meanings, and evidence was used politically to bolster interests, particularly those of the food industry. This review identifies and critically analyses key arguments for and against population dietary public health policies. Our findings should motivate public health researchers and practitioners to avoid unreflexively embracing framings that draw on the languages and logics of free market economics.

RESUMO

Some tobacco companies claim they are 'transforming' by adopting harm reduction goals or even seeking to achieve a 'smokefree' world. What characterises transformation and whether companies can or are transforming is unclear. Nevertheless, such claims are gaining traction. We critically investigated tobacco industry transformation by exploring the definition and criteria for evaluating transformation, and assessed whether transformation is occurring and feasible.Companies' transformation claims centre on increasing sales of new tobacco and nicotine products like e-cigarettes ('new products') with little attention to reducing sales of more hazardous smoked and oral products ('conventional products').We define a transforming tobacco company as one demonstrating substantial, rapid and verifiable progress towards eliminating the production and sale of conventional tobacco products within 5 years in all markets where it operates.We found no evidence any tobacco company is meeting the three essential criteria of rapidly progressing towards eliminating conventional products, ceasing to obstruct effective tobacco control measures and taking action to minimise smoking uptake and disparities. While some companies are developing new product portfolios, their actions are more consistent with profit maximisation than eliminating conventional product use. This approach is best described as 'pseudo-transformation', designed to delay implementation of effective tobacco control policies. In addition, our analysis suggests replacing conventional products with new nicotine products is unlikely to be a viable long-term business model.Public health practitioners should not rely on tobacco industry claims but should lead the transformation debate, establish credible definitions and criteria, and monitor and assess whether transformation is occurring.

RESUMO

The DUX4 transcription factor is normally expressed in the cleavage-stage embryo and regulates genes involved in embryonic genome activation. Misexpression of DUX4 in skeletal muscle, however, is toxic and causes facioscapulohumeral muscular dystrophy (FSHD). We recently showed DUX4-induced toxicity is due, in part, to the activation of the double-stranded RNA (dsRNA) response pathway and the accumulation of intranuclear dsRNA foci. Here, we determined the composition of DUX4-induced dsRNAs. We found that a subset of DUX4-induced dsRNAs originate from inverted Alu repeats embedded within the introns of DUX4-induced transcripts and from DUX4-induced dsRNA-forming intergenic transcripts enriched for endogenous retroviruses, Alu and LINE-1 elements. However, these repeat classes were also represented in dsRNAs from cells not expressing DUX4. In contrast, pericentric human satellite II (HSATII) repeats formed a class of dsRNA specific to the DUX4 expressing cells. Further investigation revealed that DUX4 can initiate the bidirectional transcription of normally heterochromatin-silenced HSATII repeats. DUX4-induced HSATII RNAs co-localized with DUX4-induced nuclear dsRNA foci and with intranuclear aggregation of EIF4A3 and ADAR1. Finally, gapmer-mediated knockdown of HSATII transcripts depleted DUX4-induced intranuclear ribonucleoprotein aggregates and decreased DUX4-induced cell death, suggesting that HSATII-formed dsRNAs contribute to DUX4 toxicity.
