2015/16 seasonal vaccine effectiveness against hospitalisation with influenza a(H1N1)pdm09 and B among elderly people in Europe: Results from the I-MOVE+ project

We conducted a multicentre test-negative caseâ\u80\u93control study in 27 hospitals of 11 European countries to measure 2015/16 influenza vaccine effectiveness (IVE) against hospitalised influenza A(H1N1)pdm09 and B among people aged â\u89¥ 65 years. Patients swabbed within 7 days after onset of symptoms compatible with severe acute respiratory infection were included. Information on demographics, vaccination and underlying conditions was collected. Using logistic regression, we measured IVE adjusted for potential confounders. We included 355 influenza A(H1N1)pdm09 cases, 110 influenza B cases, and 1,274 controls. Adjusted IVE against influenza A(H1N1)pdm09 was 42% (95% confidence interval (CI): 22 to 57). It was 59% (95% CI: 23 to 78), 48% (95% CI: 5 to 71), 43% (95% CI: 8 to 65) and 39% (95% CI: 7 to 60) in patients with diabetes mellitus, cancer, lung and heart disease, respectively. Adjusted IVE against influenza B was 52% (95% CI: 24 to 70). It was 62% (95% CI: 5 to 85), 60% (95% CI: 18 to 80) and 36% (95% CI: -23 to 67) in patients with diabetes mellitus, lung and heart disease, respectively. 2015/16 IVE estimates against hospitalised influenza in elderly people was moderate against influenza A(H1N1)pdm09 and B, including among those with diabetes mellitus, cancer, lung or heart diseases

Safety assessment of the substance Ln 1,4-benzene dicarboxylic acid (with Ln = La, Eu, Gd, Tb) for use in food contact materials

The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel) assessed the safety of the additive Ln 1,4-benzene dicarboxylic acid (with Ln = La, Eu, Gd, Tb) for use in food contact materials. It is a family of mixtures combining the four lanthanides lanthanum (La), europium (Eu), gadolinium (Gd) and/or terbium (Tb) in different proportions as their 1,4-benzene dicarboxylate complexes, used as a taggant in plastics for authentication and traceability purposes. The powdered additive, not in nano form, is intended to be used at up to 100 mg/kg in polyethylene, polypropylene and polybutene. Materials and articles made of these plastics are intended for contact with all foods types at up to 4 h/100 degrees C or for long-term storage at ambient temperature. In tests with food simulants, migration of each Ln was below 5 mg/kg. The Panel considered that irrespective of the composition of the lanthanides, these would dissociate completely from the terephthalic acid salt under aqueous conditions. Evaluation of the genotoxicity studies provided on the individual complexes (La, Eu, Gd and Tb) and on their mixture, taken together with data available in the scientific literature, allows ruling out concern for genotoxicity. Consequently, the CEP Panel concluded that the substance Ln 1,4-benzene dicarboxylic acid (with Ln = La, Eu, Gd, Tb) does not raise a safety concern for the consumer under the proposed conditions of use and if the migration of the sum of the four lanthanides in ionic form does not exceed 50 mu g/kg food

Safety assessment of the active substance polyacrylic acid, sodium salt, cross-linked, for use in active food contact materials

The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of polyacrylic acid, sodium salt, cross-linked, FCM substance No 1015, which is intended to be used as a liquid absorber in the packaging of fresh or frozen foods such as meat, poultry and seafood as well as fresh fruits and vegetables. Specific migration tests were not performed due to the high absorption of liquids by the substance. The Panel noted that if polyacrylic acid, sodium salt, cross-linked is used not in direct contact with food and placed in a pad under conditions where its absorption capacity is not exceeded, then no migration is to be expected and therefore no exposure from the consumption of the packed food is expected. The Panel also considered that the non-cross-linked polymer and the cross-linkers do not raise a concern for genotoxicity. The CEP Panel concluded that the use of this polyacrylic acid, sodium salt, cross-linked, does not raise a safety concern when used in absorbent pads in the packaging of fresh or frozen foods. The absorbent pads must be used only under conditions in which the absorption capacity of the active substance is not exceeded and direct contact with food is excluded

Safety assessment of the substance, montmorillonite clay modified with hexadecyltrimethylammonium bromide, for use in food contact materials

The EFSA Panelon Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of montmorillonite clay modified with hexadecyltrimethylammonium bromide (HDTA) when used as an additive at up to |||| in polylactic acid (PLA) bottles intended for contact with water for long-term storage at ambient temperature or below. The modified clay, which 90% w/w of the particles have a dimension of 33.1m or less and the average size is 9m, has a layered structure with layers of a thickness below 100nm. When incorporated in PLA, nanosized layers can be dispersed in the matrix, but are not expected to migrate. Thermal degradation is not expected at the maximum manufacturing temperature. No loss of integrity of the PLA surface due to interaction with bottled water was observed. The overall migration was very low. No migration of HDTA was detected at the limit of detection |||||. Migration of aluminium was below or at the limit of detection |||||, which would conservatively correspond to approximately ||||. Comparative analysis of bottled water with and without the modified clay did not reveal additional peaks corresponding to impurities identified in the modifier and/or in the modified clay. Moreover, |||||, and the modifier HDTA have been evaluated and authorised. Therefore, the CEP Panelconcluded that the substance montmorillonite clay modified with HDTA bromide is not of safety concern for the consumer if the substance is used as an additive at up to |||| in PLA plastic bottles and other containers intended for long-term storage of water at ambient temperature or below, as requested by the applicant
