Effects of an educational planetary plate graphic on meat consumption in a Stanford University dining hall: a randomized controlled trial

Abstract Background Assess the impact of an educational Planetary Health Plate (PHP) graphic on meat-related dietary choices of Stanford University dining hall patrons using a randomized controlled trial crossover design. All patrons entering the dining hall during study periods were enrolled as participants. Control, n = 631; PHP, n = 547. Methods Compare dietary behavior without signage to behavior while exposed to PHP during four equivalent dinner meals. The primary outcome was total meat-dish weight adjusted for the number of people entering the dining hall. Secondary outcomes included the number of meat-dish servings and average meat-dish serving weight. Analysis using T-tests, Poisson generalized linear model. Results Differences in total meat-dish weight, (1.54 kg; 95% Confidence Interval [CI] = -4.41,1.33; P = .19) and average meat-dish serving weight (0.03 kg; 95% CI = 0.00, 0.06; P = .07) between PHP and control patrons did not reach significance. The rate at which PHP patrons took meat was significantly lower (Incidence Rate Ratio 0.80; 95% CI = 0.71, 0.91; P < .001). Conclusion Exposure to an educational plate graphic decreased the proportion of patrons taking meat but had no impact on total meat consumption or meat-dish serving weight. Statistical methods used in this study may inform future investigations on dietary change in the dining hall setting. Further research on the role of educational signage in influencing dietary behavior is warranted, with an aim to improve human health and environmental sustainability.

Applications of capillary electrophoresis to the analysis of compounds of clinical, forensic, cosmetological, environmental, nutritional and pharmaceutical importance

Since its inception in the 80's, capillary electrophoresis has matured into a well-established separation technique, actually encompassing a family of electrodriven techniques with distinct separation mechanisms and selectivity, performed in a single capillary column. In this work, the versatility of capillary electrophoresis in handling materials from a diversity of chemical classes and complex sample matrices is illustrated by representative applications in the clinical, forensic, cosmetological, environmental, nutritional and pharmaceutical areas, grouping together our own research interests and results

Analisi fitobatteriologiche, necessarie per i servizi fitosanitari regionali

The Legislative Decree n.214 dated 19-9-2005 introduced in Italy the Council Directive 2000/29/CE, as amended by the Council Directive 2002/89/CE. The aforesaid Decree enforced protective measures against the introduction and spread into the Community of organisms harmful to plants/plants products. In the annexes of the Decree, there are 20 phytopathogenic bacteria. The key measures foreseen in the Decree are strengthened plant health checks, carried out by the regional Plant Health Services (SFR) at the place of production and on imported/exported plants/plant products. In this respect, laboratory analyses are essential for the detection of latent infections. Currently, the analyses are carried out in laboratories belonging to SFR or, under the supervision of each SFR, in private or public laboratories. The Decree 214/2005 lays down a national laboratory network (art.53) to support SFR in performing their analyses. The network operates under the supervision of a central Phytosanitary Committee (art.52). In 2006, a special inquiry showed that SFR are characterised by different needs as they perform different bacteriological analyses for the crops grown in their areas and for the checks of other materials imported through the relevant points of entry. Nevertheless three quarantine bacteria resulted to be of common interest. The national laboratory network, laid down by the Decree 214/2005, should take into account the demand for analyses expressed by the SFR, that have already provided useful data regarding their bacteriological needs. This national laboratory network could provide the SFR with an effective support also in the control of regulated non quarantine pests
