The global growing rates of cognitive decline and dementia, together with the absence of curative therapies for these conditions, support the interest in researching potential primary prevention interventions, with particular focus on dietary habits. The aim was to assess the association between polyphenol intake and 6-year change in cognitive function in the ‘Seguimiento Universidad de Navarra’ (SUN) Project, a Spanish prospective cohort study. Changes (final – initial) in cognitive function were evaluated in a subsample of 806 participants (mean age 66 (sd 5) years, 69·7 % male) of the SUN Project using the validated Spanish Telephone Interview for Cognitive Status-modified score. Polyphenol intake was derived from a validated semi-quantitative FFQ and matching food composition data from the Phenol-Explorer database. Multivariable linear regression models were used to evaluate the association between total polyphenol intake, polyphenol subclasses and cognitive changes. No significant association between total polyphenol intake and changes in cognitive function was found. However, a higher intake of lignans (βQuintile (Q) 5 v. Q1 0·81; 95 % CI 0·12, 1·51; Ptrend = 0·020) and stilbenes (βQ5 v. Q1 0·82; 95 % CI 0·15, 1·49; Ptrend = 0·028) was associated with more favourable changes in cognitive function over time, particularly with respect to immediate memory and language domains. Olive oil and nuts were the major sources of variability in lignan intake, and wine in stilbene intake. The results suggest that lignan and stilbene intake was associated with improvements in cognitive function.
To assess whether higher adherence to the traditional Mediterranean diet (MedDiet) was associated with lower consumption of ultra-processed foods (UPF) and lower free sugar intake.
Cross-sectional analysis of baseline information among participants in the SENDO project, a Spanish paediatric cohort. Dietary information was collected through a semi-quantitative FFQ. Food items were classified according to the NOVA classification. Adherence to the MedDiet was evaluated through the KIDMED index.
Three hundred eight-six children (52 % boys) with a mean age of 5·3 years old (sd 1·0) were included in the analysis.
74·4 % of the children had moderate adherence to the MedDiet (mean KIDMED score: 5·9 points; sd 1·7) and overall, 32·2 % of the total energy intake came from UPF. Each two additional points in the KIDMED score was associated with 3·1 % (95 % CI 2·1, 4·0) lower energy intake from UPF. Compared to those with low adherence to the MedDiet, children with medium and high adherence reported 5·0 % (95 % CI 2·2, 7·7) and 8·5 % (95 % CI 5·2, 11·9) lower energy intake from UPF, respectively. We also found that 71·6 % of the variability in free sugar intake was explained by the variability in UPF consumption.
Adherence to the traditional MedDiet was inversely associated with energy intake from UPF. Furthermore, most of the variability in free sugar intake was explained by the variability of UPF consumption. Public health strategies are needed to strengthen the adherence to the MedDiet in pre-schoolers while regulating the production, marketing and advertising of UPF.
In the conclusions, the book editors assess the existing national and international regulatory frameworks in the light of the five foundational principles that they identified by reading international bioethics law in conjunction with international human rights standards: (i) freedom of research; (ii) benefit sharing; (iii) solidarity; (iv) respect for dignity; and (v) the obligation to respect and to protect the rights and individual freedoms of others. Their analysis reveals four issues common to most national regulatory frameworks as well as the international framework: (i) The prohibition to create embryos for research embryos cannot be reconciled with the right to science and the rights of science; (ii) limitations to scientific freedom based on vague laws are not truly limitations “determined by law”; (iii) limitations to scientific freedom based on obsolete laws are not limitations accepted in a “democratic society”; (iv) ne plus ultra prohibitions breach the right of everyone to benefit from scientific and technological progress and the principle of benefit sharing. The editors conclude by sketching an international governance framework that promotes science and technological development while being mindful and respectful of international human rights standards, as well as the different sensitivities with which citizens from different parts of the world approach the question of human germline genome modification.
In this chapter, we review the key elements of the larger international and transnational framework within which the national legal regimes regulating human germline genome modification exist. Part I is a quick primer to international law and international human rights for the benefit of those who are not familiar with them. Part II presents the relevant norms of international bioethics law, including three main declarations adopted by UNESCO touching on human genome modification. It discusses also the relevant governance activities of the World Health Organization, Organisation for Economic Co-operation and Development and civil society, nationally and transnationally. Part III discusses relevant international human standards, and in particular the so-called ‘right to science’ and the ‘rights of science’. Finally, Part IV discusses how these rights can contribute to the emerging international regulatory framework. This chapter argues that, by itself, international bioethics law and its instruments provide a narrow and inadequate description of the range of human rights that must be taken into account in the conversation on the regulation of germline engineering. These instruments must be integrated with the broader international human rights law corpus. When they are integrated, five key principles emerge as foundations of the emerging regulatory framework: freedom of research; benefit sharing; solidarity; respect for dignity; and the obligation to respect and to protect the rights and individual freedoms of others.
In this Introduction (Chapter 1), we discuss the science of human genome modification in general, how it relates to human reproduction, and the specific advances that CRISPR/Cas 9 represents and the family of tools it has generated to date. We then explain the methodology we followed preparing this book, including how countries were selected and what we chose to focus on and why.
