Objectives. To evaluate the impact of a national law banning sales of competitive food and beverages (CF&B) in schools on the availability of CF&B sold at school kiosks. Methods. This study was uncontrolled before and after study. We evaluated public schools in Santiago de Chile (n = 21; 78% response rate) in 2014 and 2016 (6 months after the law came into force). Trained personnel collected data on calories, total sugars, saturated fat, and sodium from food labels. The outcome was the percentage of foods exceeding the cutoff levels defined in the law and the mean difference between 2014 and 2016. Results. Foods exceeding any cutoffs decreased from 90.4% in 2014 to 15.0% in 2016. Solid products had a substantial reduction in calories, sugar, saturated fat, and sodium. Liquid products had a reduction in calories, total sugar, and saturated fat, whereas sodium increased. This was a result of changes in product mix. Conclusions. A ban on sales of CF&B reduced the availability of CF&B at Santiago’s school kiosks. Further research should examine the impact of this ban on food intake and health outcomes.
BackgroundBacterial mediastinitis is a severe complication after open heart surgery. The infection causes prolonged hospitalization and an increased mortality risk. Observations from orthopaedic surgery showed that the suction catheter used during surgery is commonly contaminated with bacteria. The aim of this study was to describe the prevalence of suction catheter contamination in cardiac surgery and to study if suction time influences the contamination risk.MethodsFifty suction catheter tips were collected during 25 aortic valve replacement operations. The suction tip was exchanged once during the operation (after aortotomy closure). The tips were subjected to bacterial contamination analysis.ResultsIn 20 of the 25 investigated cases (80%), bacterial contamination was detected on one or both tips. The tip used during the beginning of the operation showed bacterial contamination in 13/25 cases (52%) and the second tip in 12/25 (48%). In 5/25 cases (20%) both tips were contaminated. There was no association between bacterial contamination and suction time. Coagulase-negative staphylococcus was the most commonly detected microorganism.ConclusionsThe suction device should be considered as a potential source of bacterial contamination in cardiac surgery. The results suggest that the suction catheter should be replaced before key moments like valve implantation and sternal closure.
