Elimination of Nitrates Contained in Leachate by Adsorption on Mixture Bentonite-Lime and Sodium Bentonite

In this work, we studied the elimination possibility of the nitrate content in leachate of a technical burying centre (Boumergued / Algeria) by  adsorption on sodium bentonite  of Maghnia and mixture bentonite-lime. The tests have been realized in synthetic solutions of distilled water. The adsorption results show rapid kinetics at the ends of a duration exceeding 2 hours to sodium bentonite, this time decreases to 20 minutes for the bentonite-lime mixture, with elimination rates equal to 45% and 96% respectively

Parasitisme dans la filière des produits de la pêche au Maroc : Éléments d'évaluation et de gestion du risque

Cet article décline, d’une part, une évaluation du risque parasitaire dans la filière des produits de la pêche au Maroc et, d’autre part, la détermination en rapport avec la gestion du risque, des implications pour l’autorité compétente nationale et les professionnels découlant des nouvelles dispositions de la réglementation européenne sur les parasites du poisson. Le risque a été évalué par l’étude des données historiques représentées par les notifications du système RASFF (Rapid Alert System for Food and Feed) ainsi que celles des services vétérinaires. Les nouvelles dispositions de la réglementation (règlement n°1276/2011 de la commission du 8 décembre 2011 modifiant l’annexe III du règlement (CE) n°853/2004 du Parlement européen et du Conseil) concerne les traitements visant à tuer les parasites viables dans les produits de la pêche destinés à la consommation humaine, lesquelles dispositions tiennent compte de l’avis scientifique de l’autorité européenne de sécurité des aliments (EFSA, 2010). Mots clés: Evaluation du risque, Parasite, Anisakis, Produits de la pêche, Maroc.   Abstract This article evaluates pest risk in the sector of fishery products in Morocco and its implications for the national authority and professionals, in regard to risk management, from the new provisions of the European regulations on fish parasites. The risk was evaluated by the study of historical data represented by the RASFF notifications (Rapid Alert System for Food and Feed) as well as from veterinary services. The new provisions of EU regulation (Regulation No 1276/2011 of the Commission of 8 December 2011 amending Annex III of Regulation (EC) No 853/2004 of the European Parliament and the Council) regarding the treatment to kill viable pests in fishery products intended for human consumption, which provisions take into account the scientific opinion from the European Food Safety Authority (EFSA, 2010). Keywords: Risk assessment, Parasitic, Anisakis, Fishery products, Morocco. &nbsp

Pancreatic surgery outcomes: multicentre prospective snapshot study in 67 countries

Background: Pancreatic surgery remains associated with high morbidity rates. Although postoperative mortality appears to have improved with specialization, the outcomes reported in the literature reflect the activity of highly specialized centres. The aim of this study was to evaluate the outcomes following pancreatic surgery worldwide.Methods: This was an international, prospective, multicentre, cross-sectional snapshot study of consecutive patients undergoing pancreatic operations worldwide in a 3-month interval in 2021. The primary outcome was postoperative mortality within 90 days of surgery. Multivariable logistic regression was used to explore relationships with Human Development Index (HDI) and other parameters.Results: A total of 4223 patients from 67 countries were analysed. A complication of any severity was detected in 68.7 percent of patients (2901 of 4223). Major complication rates (Clavien-Dindo grade at least IIIa) were 24, 18, and 27 percent, and mortality rates were 10, 5, and 5 per cent in low-to-middle-, high-, and very high-HDI countries respectively. The 90-day postoperative mortality rate was 5.4 per cent (229 of 4223) overall, but was significantly higher in the low-to-middle-HDI group (adjusted OR 2.88, 95 per cent c.i. 1.80 to 4.48). The overall failure-to-rescue rate was 21 percent; however, it was 41 per cent in low-to-middle-compared with 19 per cent in very high-HDI countries.Conclusion: Excess mortality in low-to-middle-HDI countries could be attributable to failure to rescue of patients from severe complications. The authors call for a collaborative response from international and regional associations of pancreatic surgeons to address management related to death from postoperative complications to tackle the global disparities in the outcomes of pancreatic surgery (NCT04652271; ISRCTN95140761)
