Does a social/behavioural gradient in dental health exist among adults? A cross-sectional study

Objective To explore the potential presence of a social/behavioural gradient in dental health among Italian adults using a cross-sectional study. Methods Caries indices were recorded among 480 subjects (52.9% men, 47.1% women) who also completed a structured self-administered social and behavioural questionnaire. A social/behavioural gradient was generated as the sum of the worst circumstances recorded on the questionnaire (cariogenic diet, smoking, lowest occupational profile, brushing teeth < twice daily, lowest educational level, uneven dental examination attendance). Results Caries figures (DMFT) and the number of filled sound teeth (FS-T) were statistically significantly linked to the social/behavioural gradient (DMFT: χ(2)(9) = 20.17 p = 0.02, Z = 0.02 p = 0.99; FS-T: χ(2)(9) = 25.68 p < 0.01, Z = -4.31 p < 0.01). DMFT was statistically significantly associated with gender and with social and behavioural variables. FS-T was higher in women (p = 0.03) and was linked to smoking ( p < 0.01). Conclusions The proposed social/behavioural gradient demonstrated how subjects reporting the worst circumstances on the questionnaire exhibited the worst dental health. The use of the gradient demonstrates that health promotion and prevention cannot be compartmentalized

SUMOylation of the Forkhead Transcription Factor FOXL2 Promotes Its Stabilization/Activation through Transient Recruitment to PML Bodies

International audienceBACKGROUND: FOXL2 is a transcription factor essential for ovarian development and maintenance. It is mutated in the genetic condition called Blepharophimosis Ptosis Epicantus inversus Syndrome (BPES) and in cases of isolated premature ovarian failure. We and others have previously shown that FOXL2 undergoes several post-translational modifications. METHODS AND PRINCIPAL FINDINGS: Here, using cells in culture, we show that interference with FOXL2 SUMOylation leads to a robust inhibition of its transactivation ability, which correlates with a decreased stability. Interestingly, FOXL2 SUMOylation promotes its transient recruitment to subnuclear structures that we demonstrate to be PML (Promyelocytic Leukemia) Nuclear Bodies. Since PML bodies are known to be sites where post-translational modifications of nuclear factors take place, we used tandem mass spectrometry to identify new post-translational modifications of FOXL2. Specifically, we detected four phosphorylated, one sulfated and three acetylated sites. CONCLUSIONS: By analogy with other transcription factors, we propose that PML Nuclear Bodies might transiently recruit FOXL2 to the vicinity of locally concentrated enzymes that could be involved in the post-translational maturation of FOXL2. FOXL2 acetylation, sulfation, phosphorylation as well as other modifications yet to be discovered might alter the transactivation capacity of FOXL2 and/or its stability, thus modulating its global intracellular activity

Food sharing platforms: unlocking opportunities for digital impact reporting

Food waste prevention and reduction is considered one of the main challenges of our time. According to the UN Environment Programme, in 2019 about 931 million tonnes of food waste was generated, 61 per cent of which came from households, 26 per cent from food service and 13 per cent from retail (UNEP, 2021). In this scenario, food sharing and redistribution business models aiming at the re-use of surplus food for human consumption may represent an impactful tool to address this issue
