- The vision of legendary criminologist Cesare Lombroso to use scientific theories of individual causes of crime as a basis for screening and prevention programmes targeting individuals at risk for future criminal behaviour has resurfaced, following advances in genetics, neuroscience and psychiatric epidemiology. This article analyses this idea and maps its ethical implications from a public health ethical standpoint. Twenty-seven variants of the new Lombrosian vision of forensic screening and prevention are distinguished, and some scientific and technical limitations are noted. Some lures, biases and structural factors, making the application of the Lombrosian idea likely in spite of weak evidence are pointed out and noted as a specific type of ethical aspect. Many classic and complex ethical challenges for health screening programmes are shown to apply to the identified variants and the choice between them, albeit with peculiar and often provoking variations. These variations are shown to actualize an underlying theoretical conundrum in need of further study, pertaining to the relationship between public health ethics and the ethics and values of criminal law policy.

A New Ethical Landscape of Prenatal Testing: Individualizing Choice to Serve Autonomy and Promote Public Health: A Radical Proposal
- 2015

Ingår i: Bioethics. - : Wiley. - 0269-9702 .- 1467-8519. ; 29:1, s. 36-45

Tidskriftsartikel (refereegranskat)abstract
- A new landscape of prenatal testing (PNT) is presently developing, including new techniques for risk-reducing, non-invasive sampling of foetal DNA and drastically enhanced possibilities of what may be rapidly and precisely analysed, surrounded by a growing commercial genetic testing industry and a general trend of individualization in healthcare policies. This article applies a set of established ethical notions from past debates on PNT for analysing PNT screening-programmes in this new situation. While some basic challenges of PNT stay untouched, the new development supports a radical individualization of how PNT screening is organized. This reformation is, at the same time, difficult to reconcile with responsible spending of resources in a publicly funded healthcare context. Thus, while the ethical imperative of individualization holds and applies to PNT, the new landscape of PNT provides reasons to start rolling back the type of mass-screening programmes currently established in many countries. Instead, more limited offers are suggested, based on considerations of severity of conditions and optimized to simultaneously serve reproductive autonomy and public health within an acceptable frame of priorities. The new landscape of PNT furthermore underscores the ethical importance of supporting and including people with disabilities. For the very same reason, no ban on what may be analysed using PNT in the new landscape should be applied, although private offers must, of course, conform to strict requirements of respecting reproductive autonomy and what that means in terms of counselling.

Tidskriftsartikel (refereegranskat)abstract
- There are a few things which are obviously a central part of everyone’s life, at all times, and all over the globe, and which are crucial for our wellbeing. Food is, like sex, such an essential ingredient of our life, an ingredient of what we expect of a good life. What is on our plates is always a result of nature and culture, to the extent that it may seem hard to find commonalities in our global diet. As academics we have asked different questions about food. For a long time these questions have been dominated by the quest to secure enough food and to improve what we have got. It is, however, noteworthy that we also always have asked the normative questions in relation to food: Is it right to eat this kind of food? Do we produce our food the right way? Is there injustice and bad power in the way we distribute the food? Are we lied to in regard to what is on our plate? When we enter the normative realm, we enter the realm of ethics, understood in a wide and comprehensive way. As all normative questions, we need to be well informed by knowledge about how the world is, and what is at stake and for whom. We call this food ethics. Food ethics raises issues and asks questions in relation to food all along the value chains. It also puts things into relation with each other. At the same time it disentangles complex heaps of factors and pieces of knowledge, and looks for guidance. It is issue driven, rather than interest driven. It unites scholars with farmers and fishermen, chefs with industry, consumers with lawyers, and food citizens with authorities. As a young field within academia it is important to guard against efforts to appropriate the field for narrow interests, and instead to combine the natural and social sciences in analysing and addressing the challenges. We do not necessarily call for the grand ethical theory that explains it all, but rather start with the simple things in a very complex overall picture. We want to draw attention to ethically significant facts, discuss problematic developments, point to genuine dilemmas, learn about food relevant contexts and history, and look for individual, professional and institutional responses to ethical challenges and issues. Thus, one of the missions of this new journal Food Ethics, is to widen the scope and the discussion on the topic, and to be inclusive in terms of who has something to contribute to the field. There is no escaping from confronting very complex issues when it comes to managing one of the most basic needs we all have, food. As editors of this new journal we maintain that food ethics deserves special and inter-disciplinary attention by researchers, that it is not sufficiently dealt with by what is currently known as bioethics, that it is intrinsically connected with the so-called grand societal challenges of our time, that it is a globally important field which demands particular attention to complexities and uncertainties, as much as it needs to be explicit about what values are at stake and for whom, and which normative principles it touches upon.

Evidence for wastewaters as environments where mobile antibiotic resistance genes emerge

Tidskriftsartikel (refereegranskat)abstract
- The emergence and spread of mobile antibiotic resistance genes (ARGs) in pathogens have become a serious threat to global health. Still little is known about where ARGs gain mobility in the first place. Here, we aimed to collect evidence indicating where such initial mobilization events of clinically relevant ARGs may have occurred. We found that the majority of previously identified origin species did not carry the mobilizing elements that likely enabled intracellular mobility of the ARGs, suggesting a necessary interplay between different bacteria. Analyses of a broad range of metagenomes revealed that wastewaters and wastewater-impacted environments had by far the highest abundance of both origin species and corresponding mobilizing elements. Most origin species were only occasionally detected in other environments. Co-occurrence of origin species and corresponding mobilizing elements were rare in human microbiota. Our results identify wastewaters and wastewater-impacted environments as plausible arenas for the initial mobilization of resistance genes.

- Seaweed is a promising sustainable source of vegan protein as its farming does not require arable land, pesticides/insecticides, nor freshwater supply. However, to be explored as a novel protein source the content and nutritional quality of protein in seaweed need to be improved. We assessed the influence of pH-shift processing on protein degree of hydrolysis (%DH), protein/peptide size distribution, accessibility, and cell bioavailability of Ulva fenestrata proteins after in vitro gastrointestinal digestion. pH-shift processing of Ulva, which concentrated its proteins 3.5-times, significantly improved the %DH from 27.7±2.6% to 35.7±2.1% and the amino acid accessibility from 56.9±4.1% to 72.7±0.6%. Due to the higher amino acid accessibility, the amount of most amino acids transported across the cell monolayers was higher in the protein extracts. Regarding bioavailability, both Ulva and protein extracts were as bioavailable as casein. The protein/peptide molecular size distribution after digestion did not disclose a clear association with bioavailability.

- Influenza A virus (IAV) has its natural reservoir in wild waterfowl, and emerging human IAVs often contain gene segments from avian viruses. The active drug metabolite of oseltamivir (oseltamivir carboxylate [OC]), stockpiled as Tamiflu for influenza pandemic preparedness, is not removed by conventional sewage treatment and has been detected in river water. There, it may exert evolutionary pressure on avian IAV in waterfowl, resulting in the development of resistant viral variants. A resistant avian IAV can circulate among wild birds only if resistance does not restrict viral fitness and if the resistant virus can persist without continuous drug pressure. In this in vivo mallard (Anas platyrhynchos) study, we tested whether an OC-resistant avian IAV (H1N1) strain with an H274Y mutation in the neuraminidase (NA-H274Y) could retain resistance while drug pressure was gradually removed. Successively infected mallards were exposed to decreasing levels of OC, and fecal samples were analyzed for the neuraminidase sequence and phenotypic resistance. No reversion to wild-type virus was observed during the experiment, which included 17 days of viral transmission among 10 ducks exposed to OC concentrations below resistance induction levels. We conclude that resistance in avian IAV that is induced by exposure of the natural host to OC can persist in the absence of the drug. Thus, there is a risk that human-pathogenic IAVs that evolve from IAVs circulating among wild birds may contain resistance mutations. An oseltamivir-resistant pandemic IAV would pose a substantial public health threat. Therefore, our observations underscore the need for prudent oseltamivir use, upgraded sewage treatment, and surveillance for resistant IAVs in wild birds.
