Use and understanding of nutrition information on food labels in six European countries

Aim: The goal of the study was to investigate the use of nutrition information on food labels and understanding of guideline daily amount (GDA) front-of-pack nutrition labels in six European countries. Subjects and methods: In-store observations and in-store interviews were conducted in major retailers in the UK (n = 2019), Sweden (n = 1858), France (n = 2337), Germany (n = 1963), Poland (n = 1800) and Hungary (n = 1804), supplemented by questionnaires filled out at home and returned (overall response rate 50.3%). Use of labels was measured by combining in-store observations and in-store interviews on concrete purchases in six product categories. Understanding of GDA front-of-pack nutrition labels was measured by a variety of tasks dealing with conceptual understanding, substantial understanding and health inferences. Demographics, nutrition knowledge and interest in healthy eating were measured as potential determinants. Results: Across six product categories, 16.8% of shoppers were found to have looked for nutrition information on the label, with the nutrition grid (table or list), GDA labels and the ingredients list as the main sources consulted and calories, fat and sugar the information most often looked for. Understanding of GDA labels was high in the UK, Sweden and Germany, and more limited in the other countries. Regression analysis showed that, in addition to country-specific differences, use and understanding are also affected by differences in interest in healthy eating and in nutrition knowledge and by social grade. Conclusion: Understanding of nutrition information seems to be more widespread than use, suggesting that lack of use is a question of not only understanding, but also motivation. Considerable national differences exist in both understanding and use, some of which may be attributed to different histories of the role of nutrition in the public debate

Service users’ first accounts of experiencing endings from a psychological service or therapy: a systematic review and meta-ethnographic synthesis

Purpose: To review and synthesis the qualitative literature on service users’ experiences of endings from a psychological service or therapy. Methods: A systematic search of the peer-reviewed literature was conducted. Studies were identified using specific inclusion criteria and included in the synthesis. A modified CASP tool was used to critically appraise the quality of the papers. A meta-ethnographic approach was used to synthesize the findings from the included studies. Results: Twelve papers were identified which met the inclusion criteria. The interpretation of findings suggested three key themes: anticipation of ending, service user control and sense of responsibility. Studies were geographically spread and of high quality. Conclusions: The review highlights the importance of service users’ perspectives in understanding the experiences of endings. The findings complement existing literature and provide new interpretations. Considerations for practice in the UK were limited however the review does provide directions for future research

Targeting Antibody Responses to the Membrane Proximal External Region of the Envelope Glycoprotein of Human Immunodeficiency Virus

Although human immunodeficiency type 1 (HIV-1) infection induces strong antibody responses to the viral envelope glycoprotein (Env) only a few of these antibodies possess the capacity to neutralize a broad range of strains. The induction of such antibodies represents an important goal in the development of a preventive vaccine against the infection. Among the broadly neutralizing monoclonal antibodies discovered so far, three (2F5, Z13 and 4E10) target the short and hidden membrane proximal external region (MPER) of the gp41 transmembrane protein. Antibody responses to MPER are rarely observed in HIV-infected individuals or after immunization with Env immunogens. To initiate antibody responses to MPER in its membrane-embedded native conformation, we generated expression plasmids encoding the membrane-anchored ectodomain of gp41 with N-terminal deletions of various sizes. Following transfection of these plasmids, the MPER domains are displayed on the cell surface and incorporated into HIV virus like particles (VLP). Transfected cells displaying MPER mutants bound as efficiently to both 2F5 and 4E10 as cells transfected with a plasmid encoding full-length Env. Mice immunized with VLPs containing the MPER mutants produced MPER-specific antibodies, the levels of which could be increased by the trimerization of the displayed proteins as well as by a DNA prime-VLP boost immunization strategy. Although 2F5 competed for binding to MPER with antibodies in sera of some of the immunized mice, neutralizing activity could not be detected. Whether this is due to inefficient binding of the induced antibodies to MPER in the context of wild type Env or whether the overall MPER-specific antibody response induced by the MPER display mutants is too low to reveal neutralizing activity, remains to be determined
