ABSTRACT
We conducted a systematic scoping review to map the available evidence on smoke-free or tobacco-free (SF/TF) university policies globally. We specifically looked at (i) how policies were developed and communicated and (ii) what indicators were used to evaluate their impact. We searched for peer-reviewed literature, published up to January 2020, across 10 multi-disciplinary databases. We followed a duplicate, independent data selection, and charting process. We inductively categorized the studies according to the research design and objective of 'process' and 'impact evaluation'. We identified 75 unique studies across 23 countries conducted between 1993 and 2019. Most studies were conducted in the United States (46/75, 61.3%), were based on quantitative research design and focused on impact evaluations; a third (n = 28) reported both process and impact evaluations (37.3%). Community engagement and multi-channel communication strategies were mostly used to disseminate SF/TF policies. The impact was determined by a wide range of indicators for knowledge, attitudes and behaviors related to policies. There is a mature, relevant body of literature describing the development and evaluation of SF/TF policies in universities. Future reviews could quantify the impact of the bans and may consider process indicators as moderating factors to explain the potential heterogeneity of results.

AIM OF THE STUDY: To valorize fish by-products oil by investigating its effects on dyslipidemia, hyperglycemia, reverse cholesterol transport and paraoxonase-1 activity in obese rat. METHODS: Sixteen male Wistar rats were fed a high fat diet. At 400 ± 10 g, obese rats were randomly divided into two groups: the first received 20% of sardine by-products oil and the second 20% of the edible portion oil. At d28, glycemia and serum lipids concentrations were estimated. High density lipoproteins (HDL2 and HDL3) were separated and their contents and composition in lipids and apolipoproteins were analyzed. Lecithin: cholesterol acyltransferase and paraoxonase-1 activities were assessed. RESULTS: In group which consumed sardine by-products oil, serum cholesterol and triacylglycerols were reduced (-8% and -36%, respectively). However, glycemia was similar. HDL3-phospholipids, HDL3-unesterified cholesterol and HDL3-apolipoproteins were decreased by 56%, 10% and 12%, respectively. Lecithin: cholesterol acyltransferase activity was increased by 35% and the content of HDL2-cholesteryl esters was elevated by 12%. Serum paraoxonase-1 activity was increased by 25%. CONCLUSION: In obese rat, sardine by-products oil may have a protective effect against cardiovascular risk by improving the anti-atherogenic metabolic pathway of cholesterol and triacylglycerols. This anti-atherogenic action is particularly enhanced by the increase in paraoxonase-1 activity which protects lipoproteins from oxidation.
